Subject: [PATCH 040/438] Reduce redundant basic blocks during code generation
 phase

here are many redundant basic blocks during code generation phase, which will
increase the size of LLVM-IR and impact the code generation efficiency. Adding
an optimization pass at the end of the linearizing phase to remove redundant basic blocks.

Issue: https://gitee.com/openharmony/arkcompiler_ets_runtime/issues/I7FHUM

Testing: test262/test262-aot/unittest/workload

Subject: [PATCH 048/438] Enhance type infer for array types

When declaring an array variable through the Array's method,
type information will be lost on IR even though there is a type annotation in source code.
We need to support this scenario.

Issue:
https://gitee.com/openharmony/arkcompiler_ets_runtime/issues/I7JNLD

Test:
typeinfer test

+# Circuit IR可视化工具开发说明
+
+若当前工具功能不满足开发者需求，开发者需增强工具能力，则可基于已有源码进行工具二次开发，编译打包生成自定义的工具。
+
+## 使用场景
+
+1. 编译打包发布工具
+
+2. 开发者需增强工具能力，进行二次开发
+
+## 工具开发
+
+### 环境说明
+
+系统：建议Ubuntu 20.04或者Windows 10
+
+### 约束
+
+nodejs v14.20.0
+
+#### 首次下载源码后安装依赖库：
+
+1.右键windows开始菜单，单击运行，输入cmd，单击确定。
+	
+2.在命令行中进入到circuit_viewer目录下，运行npm i安装依赖库，如下图所示：
+	
+![](../figures/install.png)
+
+#### 打包
+
+首次使用工具或本地代码有更新时，需在circuit_viewer目录下运行npm run dist打包源码，如下图所示：
+
+![](../figures/dist.png)
+
+打包成功后会生成dist/main.js文件
+
+#### 运行
+
+本地安装python3，在dist目录内运行python -m http.server启动web服务，如下图所示：
+
+![](../figures/start_web.png)
+
+打开chrome浏览器，访问127.0.0.1:8000，如下图所示：
+
+![](../figures/run.png)
+
+#### 发布
+
+将dist目录下的文件放到web服务器根目录，必要的文件列表如下：
+
+config.json ---- 配置节点和线的颜色
+favicon.ico ---- 页面打开后左上角的图标
+index.html ----- 页面入口文件
+main.js -------- 打包发布的工具主程序文件
+
+#### 开发
+
+源码中，engine目录为自研图形引擎，跟circuit ir相关文件有如下三个：
+
+1. 解析log文件：src/ir/LogParser.js
+
+2. 根据解析结果生成节点和线：src/ir/IrToPicture.js
+
+3. 可视化展示流图：src/ir/IrViewer.js
+
+开发者可以对以上三个文件进行二次开发，增强工具能力
+
+#### 调试
+
+1. 安装chrome浏览器
+
+2. 使用vscode打开工程，创建.vscode目录，新建launch.json(调试配置)，如下图：
+
+![](../figures/vscode_launch.png)
+
+3. 新建task.json(打包配置)，如下图：
+   
+![](../figures/vscode_task.png)
+
+4. 在vscode界面点击F5，将会自动打包和启动调试，在src的源码中可以下断点调试

+# Circuit IR可视化工具使用说明
+
+## 简介
+
+Circuit IR可视化工具支持将ark_aot_compiler命令行生成的log展示成流图，以便分析。
+
+### 使用说明
+
+生成log需要在ark_aot_compiler命令行后面添加参数：--compiler-log=all012 --log-level=info
+
+根据开发说明打包工具，并运行起来：
+
+[开发说明](./DEVELOP_zh.md)
+
+将log拖入浏览器窗口区域，等待解析完成，界面功能如下图所示：
+
+![](../figures/operate.png)
+
+节点颜色和选中节点后线的颜色可以在dist/config.json中配置
+
+拖动画面有3个方法：
+
+1，鼠标右键按住拖动
+
+2，鼠标滚轮上下滚动
+
+3，右侧和底部的滚动条
+
+## 注意
+
+暂无

+# Circuit Viewer可视化工具单元测试
+
+## 概述
+为了验证代码与设计相符合，跟踪需求和设计的实现，发现设计和需求中存在的错误。需要用单元测试检验被测代码的一个很小的、明确的功能是否正确。
+本文主要介绍Circuit Viewer可视化工具单元测试使用指导。

+						  └── README.md         # 指导文档    
+
+## 软件环境准备
+
+依赖版本：python3.8
+
+1.右键windows开始菜单，单击运行，输入cmd，单击确定。
+
+2.在命令行中进入到circuit_viewer\test目录下，安装依赖库命令如下：
+
+	pip install -r requirements.txt
+
+3.查看谷歌浏览器版本，此处得到浏览器版本为101.0.4951.67，查询网址如下：
+
+[查看浏览器版本](chrome://version/)
+
+4.由于浏览器版本为101.0.4951.67，查看驱动版本列表中是否有101.0.4951.67版本，若有可下载此版本驱动；若没有可下载101.0.4951最小版本，此处选择101.0.4951.15版本。进入版本系统选择列表后，选择win32（win系统不区分win32或win64）下载压缩包，下载地址如下：
+
+[驱动下载地址](http://npm.taobao.org/mirrors/chromedriver/)
+
+5.将解压缩获得的驱动文件放入python根目录下：
+
+## 使用说明
+
+在命令行中进入到circuit_viewer\test目录下：
+
+1.执行所有用例，命令为：
+
+	pytest -s -W ignore test_viewer.py
+
+2.执行单个用例,如test_start，命令为：
+
+	pytest -s -W ignore test_viewer.py::test_start

Subject: [PATCH 113/438] AOT Type-Based Polymorphic Property Access

1. Support polymorphic named property access in TSHCRLowering.
2. Merge the process of loading and storing as access.
3. Intruduce a new class ObjectAccessHelper to let TSHCRLowering pay more
   attention to the process of graph.
4. Triple improvement in micro polymorphism performance test. (250->80)

Issue: https://gitee.com/openharmony/arkcompiler_ets_runtime/issues/I7LEDD

Subject: [PATCH 155/438] [Feature] AOT compiler's code generator refactor.

AOT compiler's code generation module (LLVM-JIT) contains many redundant type-related logics,
which should be simplified and removed and refactored. By introducing const types variables
that can be reused during lowering-ops to make the lowering more clear and efficient.
Architecture refactoring and so that the code generator can emit more efficient and shorter
LLVM-IR that will improve the compilation time.

Testings: test262/test262aot/workload/ut

 =?UTF-8?q?=E6=A6=82=E7=8E=87=E5=87=BA=E7=8E=B0=E5=B4=A9=E6=BA=83?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

desc: allocation tracker低概率出现崩溃

reason:
当前逻辑是先stopAllocationTracker再stop定时器。可能存在stopAllocationTracker清除数据后又触发了定时器回调，这样又去访问数据，导致数组越界崩溃。

solu:
1.数组访问增加长度判断；
2.先停止定时器，再去触发stopAllocationTracker。

Current dumper dumps many details of objects, which should be simplified
and make the output contents more readable. Therefore, this pr cut some
redundant information when dumping.

Subject: [PATCH 199/438] Fix: concurrent marking may use inconsistent hclass

Issue:https://gitee.com/openharmony/arkcompiler_ets_runtime/issues/I7QZU8?from=project-issue
When main-thread transitions an object to a new hclass, concurrent
marking could load an incosistent hclass.

Subject: [PATCH 234/438] Eliminate HeapObject Check on the Elements of JSArray
 based on ElementsKind

1. If the PGO ElementsKind of a JSArray is OBJECT, and the named property of the JSArray element is loaded,
   the HeapObject check is not required.
2. The AOT stroing of OBJECT JSArray should be checked to prevent damage to the ElementsKind.

Issue: https://gitee.com/openharmony/arkcompiler_ets_runtime/issues/I7SHUY

From 3deaf264bce4c01aad958a566d64267086b238fa Mon Sep 17 00:00:00 2001
From: weng-xi <wengxi1@huawei.com>
Date: Thu, 17 Aug 2023 16:10:28 +0800
Subject: [PATCH 288/438] AOT supports typedarray types collected by PGO

1. Refactor pgo_type_infer using the strategy pattern.
2. Leverage typed array information collected by pgo, allowing JS files to enter the fast path for ldobjbyvalue.

Issue: https://gitee.com/openharmony/arkcompiler_ets_runtime/issues/I7U02G
Signed-off-by: weng-xi <wengxi1@huawei.com>

Subject: [PATCH 291/438] Bugfix in stable path of
 Array.prototype.[last]indexOf

Fixes a bug in the stable path of Array.prototype.indexOf and
Array.prototype.lastIndexOf where fromIndex is an Object with valueOf
and toString methods that have side effects to current array.

desc: 日历应用录制allocation时概率崩溃

solu:
由于AOT相关的对象类型，没有添加到DumpHeapSnapshot的类型判断里，导致当出现AOT_LITERAL_INFO类型时走到FATAL分支，从而崩溃。需要把缺失的判断类型补上。

desc: TakeHeapSnapShot数组相关性能优化二

solu:
对于array里的elements元素，其下标不以字符串的形式存在stringtable,而是直接存整数。这样可以减少生成文件shapshot的strings一栏的条目数，加快解析速度

Subject: [PATCH 328/438] Fix Serialization of AOT Method

1. After serialization and deserialization, the aot information on the method is lost, which prevents the optimized code from being executed.
2. Add test case.

From c9f42a0bc9bff016af2218b63dad967ffc3a256d Mon Sep 17 00:00:00 2001
From: wuzhefeng <wuzhefeng1@huawei.com>
Date: Sun, 20 Aug 2023 08:20:31 +0800
Subject: [PATCH 369/438] [Bug]: Fix the symbol section info (part-1)

The information of the symbols inside AOT-generated AN file should be fixed to support profiling tools parsing. After fixing the missing symbol information, the call-stack would display the functions' symbols in perf data.

+ * This module analyzes the tag distribution in a switch statement and decides
+ * the best strategy in terms of runtime performance to generate code for it.
+ * The generated code makes use of 3 code generation techniques:
+ *
+ * 1. cascade of if-then-else based on equality test
+ * 2. rangegoto
+ * 3. binary search
+ *
+ * 1 is applied only if the number of possibilities is <= 6.
+ * 2 corresponds to indexed jump, but it requires allocating an array
+ * initialized with the jump targets.  Since it causes memory usage overhead,
+ * rangegoto is used only if the density is higher than 0.7.
+ * If neither 1 nor 2 is applicable, 3 is applied in the form of a decision
+ * tree.  In this case, each test would split the tags into 2 halves.  For
+ * each half, the above algorithm is then applied recursively until the
+ * algorithm terminates.
+ *
+ * But we don't want to apply 3 right from the beginning if both 1 and 2 do not
+ * apply, because there may be regions that have density > 0.7.  Thus, the
+ * switch lowerer begins by finding clusters.  A cluster is defined to be a
+ * maximal range of tags whose density is > 0.7.
+ *
+ * In finding clusters, the original switch table is sorted and then each dense
+ * region is condensed into 1 switch item; in the switch_items table, each item // either corresponds to an original
+ * entry in the original switch table (pair's // second is 0), or to a dense region (pair's second gives the upper limit
+ * of the dense range).  The output code is generated based on the switch_items. See BuildCodeForSwitchItems() which is
+ * recursive.

+ * From "ARM Procedure Call Standard for ARM 64-bit Architecture"
+ *     ARM IHI 0055C_beta, 6th November 2013
+ * $ 5.1 machine Registers
+ * $ 5.1.1 General-Purpose Registers
+ *  <Table 2>                Note
+ *  SP       Stack Pointer
+ *  R30/LR   Link register   Stores the return address.
+ *                           We push it into stack along with FP on function
+ *                           entry using STP and restore it on function exit
+ *                           using LDP even if the function is a leaf (i.e.,
+ *                           it does not call any other function) because it
+ *                           is free (we have to store FP anyway).  So, if a
+ *                           function is a leaf, we may use it as a temporary
+ *                           register.
+ *  R29/FP   Frame Pointer
+ *  R19-R28  Callee-saved
+ *           registers
+ *  R18      Platform reg    Can we use it as a temporary register?
+ *  R16,R17  IP0,IP1         Maybe used as temporary registers. Should be
+ *                           given lower priorities. (i.e., we push them
+ *                           into the free register stack before the others)
+ *  R9-R15                   Temporary registers, caller-saved
+ *  Note:
+ *  R16 and R17 may be used by a linker as a scratch register between
+ *  a routine and any subroutine it calls. They can also be used within a
+ *  routine to hold intermediate values between subroutine calls.
+ *
+ *  The role of R18 is platform specific. If a platform ABI has need of
+ *  a dedicated general purpose register to carry inter-procedural state
+ *  (for example, the thread context) then it should use this register for
+ *  that purpose. If the platform ABI has no such requirements, then it should
+ *  use R18 as an additional temporary register. The platform ABI specification
+ *  must document the usage for this register.
+ *
+ *  A subroutine invocation must preserve the contents of the registers R19-R29
+ *  and SP. All 64 bits of each value stored in R19-R29 must be preserved, even
+ *  when using the ILP32 data model.
+ *
+ *  $ 5.1.2 SIMD and Floating-Point Registers
+ *
+ *  The first eight registers, V0-V7, are used to pass argument values into
+ *  a subroutine and to return result values from a function. They may also
+ *  be used to hold intermediate values within a routine.
+ *
+ *  V8-V15 must be preserved by a callee across subroutine calls; the
+ *  remaining registers do not need to be preserved( or caller-saved).
+ *  Additionally, only the bottom 64 bits of each value stored in V8-
+ *  V15 need to be preserved.

+   *  will be some 'base_slot_offset' + 'slot' off FP.
+   *  For simplification, entire 64bit register is spilled/filled.
+   *
+   *  For example, a virtual register home 'slot' on the stack is location 5.
+   *  This represents a 64bit slot (8bytes).  The base_slot_offset
+   *  from the base 'slot' determined by whoever is added, off FP.
+   *     stack address is  ( FP - (5 * 8) + base_slot_offset )
+   *  So the algorithm is simple, for each virtual register that is not
+   *  allocated, it has to have a home address on the stack (a slot).
+   *  A class variable is used, start from 0, increment by 1.
+   *  Since LiveInterval already represent unique regNO information,
+   *  just add a slot number to it.  Subsequent reference to a regNO
+   *  will either get an allocated physical register or a slot number
+   *  for computing the stack location.
+   *
+   *  This function will also determine the operand to be a def or use.
+   *  For def, spill instruction(s) is appended after the insn.
+   *  For use, spill instruction(s) is prepended before the insn.
+   *  Use FP - (slot# *8) for now.  Will recompute if base_slot_offset
+   *  is not 0.
+   *
+   *  The total number of slots used will be used to compute the stack
+   *  frame size.  This will require some interface external to LSRA.
+   *
+   *  For normal instruction, two spill regs should be enough.  The caller
+   *  controls which ones to use.
+   *  For more complex operations, need to break down the instruction.
+   *    eg.  store  v1 -> [v2 + v3]  // 3 regs needed
+   *         =>  p1 <- v2        // address part 1
+   *             p2 <- v3        // address part 2
+   *             p1 <- p1 + p2   // freeing up p2
+   *             p2 <- v1
+   *            store p2 -> [p1]
+   *      or we can allocate more registers to the spill register set
+   *  For store multiple, need to break it down into two or more instr.

+// This phase analyzes the defs and uses of ref pointers in the function and
+// performs the following modifications to the code:
+//
+// A. Insert a decref for the ref pointer before each of its definition.  If the
+// ref pointer is local (a localrefvar) and the analysis shows that it is the
+// first definition since entering the function, the decref will be omitted.
+//
+// B. At each statement that assigns a new value to a ref pointer, insert an
+// incref after the assignment. In cases where the incref has already been
+// performed when the assigned value is computed, it will not insert the incref.
+//
+// C. A localrefvar need to be cleaned up before function exit.  This clean-up
+// corresponds to performing a decref.  Instead of inserting a decref to clean up
+// each localrefvar, the cleanup for the localrefvars in the function is
+// represented aggregate via a call to the intrinsic CLEANUP_LOCALREFVARS
+// inserted before each return statement.  The localrefvars to be cleaned up
+// for each return statement are indicated as actual parameters in the
+// intrinsiccall statement. If a localrefvar's definition cannot reach a return
+// statement, it will not be included in the actual parameters. If the number
+// of localrefvar parameters in the intrinsiccall is more than
+// `kCleanupLocalRefVarsLimit`, the intrinsiccall will be omitted, in which
+// case the code generator will clean up all localrefvars.
+//
+// For C, analyzerc can try to do more optimization by inserting decrefs for
+// individual localrefvars earlier than the return statements.  This is done
+// when the placementRC flag is set to true. This optimization is performed by
+// calling PlacementRC::ApplySSUPre for all localrefvars.
+// Under placementRC, the CLEANUP_LOCALREFVARS intrinsiccall will still be
+// inserted for the decrefs being inserted before the return statement.
+//
+// When a formal parameter of ref type is ever assigned inside the function,
+// an incref for it needs to be inserted at function entry.  This is done
+// by the placementRC phase. For such formal parameters, placementRC phase will
+// also insert decref's to clean them up after their last use.
+//
+// If the return statement returns a ref pointer variable, an incref for it
+// needs to be effected. This is not handled by analyzerc, but is handled by
+// the rcLowering phase.
+//
+// This phase needs to be run before register promotion, because some alias
+// information is lost after a pointer is promoted to preg. Because it is run
+// after EPRE phase, there can be regassign's and regread's of ref type but
+// they will not cause decref or incref insertion.
+//
+// if number of live localrefvars is more than this limit at a return, we will
+// not insert the intrinsiccall to CLEANUP_LOCALREFVARS

+// statement; if it is a zero, then MCC_DecRef_NaiveRCFast could be removed.
+//
+// There are other conditions that the assertnonnull can be removed, e.g. if
+// the statement next to assertnonnull is an iread and the base is the
+// symbol assertnonnull is dealing with, then the assertnonnull can be removed,
+// because the exception will be thrown at this same place by iread, as the

+// This phase finds local ref pointer variables that are delegated and thus can
+// have their RC omitted.  This optimization is done on a per-SSA version basis.
+// As a result, an overall criterion is that the SSA version must not have
+// appeared as phi operand;
+//
+// There are two forms of delegation:
+//
+// Form A. The following conditions have to be satisfied for an SSA version to be
+// delegated:
+// (1) In the BB where it is defined, there is a last use of it as the assigned
+//     value in an assignment statement, which is either iassign or
+//     dassign-to-global, and the assignment statement is marked need_incref.
+// (2) Between its definition and last use, there is no statement that may
+//     potentially raise exception.
+// For each such case, the optimization is as follows:
+// (a) The SSA version is renamed to a new and unique preg with PTY_ptr type;
+//     this has the effect of eliminating its store and loads and its
+//     decref-before-return;
+// (b) The need_incref flag in the respective assignment statement is cleared.
+// The reference count correctness is maintained because the removed decref and
+// incref are for the same offect.
+//
+// Form B. An SSA version is determined to not need incref at its def and not
+// need decref when it becomes dead.  In this case, the SSA version is renamed
+// to a new and unique preg with PTY_ptr type as in (a) above.
+//
+// There are different ways to establish that an SSA version does not any RC:
+// B1: The SSA version is never dereferenced and never copied to another variable
+//     or passed on as a parameter.
+// B2: The RHS of its definition is iread of a final field with this as base or
+//     dread of a static final field.
+// B3: Within the SSA version's live range, there is no operation that can result
+//     in decref of any object.

+// 2. Process each node in the worklist. For any variable used in expression,
+//    mark the def stmt for the variable as needed and push expressions used
+//    by the def stmt to the worklist.
+// 3. When the worklist becomes empty, perform a pass over the program to delete
+//    statements that have not been marked as needed.
+//
+// The backward substitution optimization is also performed in this phase by
+// piggy-backing on Step 3.  In the pass over the program in Step 3, it counts
+// the number of uses for each variable version.  It also create a list of
+// backward substitution candidates, which are dassign statements of the form:
+//              x_i = y_j
+// where x is a local variable with no alias, and y_j is defined via the return
+// value of a call which is in the same BB.  Then,
+// 4. For each backward substitution candidate x_i = y_j, if the use count of y_j
+//    is 1, then replace the return value definition of y_j by x_i, and delete
+//    the statement x_i = y_j.
+// Before the hdse phase finishes, it performs 2 additional optimizations:
+// 5. When earlier deletion caused a try block to become empty, delete the empty
+//    try block while fixing up the CFG.
+// 6. Perform unreacble code analysis, delete the BBs found unreachable and fix
+//    up the CFG.

+// This phase builds the SSA form of a function. Before this we have got the dominator tree
+// and each bb's dominance frontiers. Then the algorithm follows this outline:
+//
+// Step 1: Inserting phi-node.
+// With dominance frontiers, we can determine more
+// precisely where phi-node might be needed. The basic idea is simple.
+// A definition of x in block b forces a phi-node at every node in b's
+// dominance frontiers. Since that phi-node is a new definition of x,
+// it may, in turn, force the insertion of additional phi-node.
+//
+// Step 2: Renaming.
+// Renames both definitions and uses of each symbol in
+// a preorder walk over the dominator tree. In each block, we first
+// rename the values defined by phi-node at the head of the block, then
+// visit each stmt in the block: we rewrite each uses of a symbol with current
+// SSA names(top of the stack which holds the current SSA version of the corresponding symbol),
+// then it creates a new SSA name for the result of the stmt.
+// This latter act makes the new name current. After all the stmts in the
+// block have been rewritten, we rewrite the appropriate phi-node's
+// parameters in each cfg successor of the block, using the current SSA names.
+// Finally, it recurs on any children of the block in the dominator tree. When it
+// returns from those recursive calls, we restores the stack of current SSA names to
+// the state that existed before the current block was visited.

+
+// This file defines the APIs that govern all messaging-styled output from
+// a running program under MAPLE, which can be a compiler or a runtime component.
+//
+// There are two overall classes of messages:
+//
+// (1) Those of interest only to developers, and thus should be suppressed in the
+// production release version of the software.  The message content will include
+// the source file and line number of the trigger point of the message.
+//
+// (2) Those intended to be visible to users of the software in general,  in
+// addition to the developers.
+//
+// Messages are divided into 6 types, or levels, from 0 to 5.  Conceptually,
+// the lower the level, the higher the frequency of occurrences, the larger the
+// output volume, the smaller the audience of interest and the more often they need
+// to be filtered out. In addition, the higher the level, the greater the severity.
+//
+// Level 0 (DBG) - These are messages for debugging purposes, used by the
+// developer during development to debug his code.
+//
+// Level 1 (LOG) - These are log messages, also for helping the developer in
+// debugging, but at a higher level of algorithmic operation.
+//
+// Level 2 (INFO) - These provide information that are of general usefulness in
+// the normal operation of the SW.
+//
+// Level 3 (WARN) - These provide warning messages.
+//
+// Level 4 (ERR) - These provide error messages.
+//
+// Level 5 (FATAL) - These indicate errors of such severity that the program r
+// execution cannot continue.
+//
+// DBG and LOG are only for developers' use.  INFO, WARN, ERR and FATAL are
+// intended for general visibility.  There is an additional type of ERR that
+// designate developer errors that arise out of checking code inserted by the
+// developers, which has the following 4 usage patterns:
+//
+// CHECK - If the specified program condition is not satisfied, output the error
+// message. The program will continue execution.
+//
+// DCHECK - Same as CHECK, but the check is suppressed in the release version of
+// the SW.
+//
+// CHECK_FATAL - If the specified program condition is not satisfied, output the error
+// message. The program will stop execution at that point.
+//
+// ASSERT - Same as CHECK_FATAL, but the check is suppressed in the release version of
+// the SW.
+//
+// The macro setting DEBUG=1 picks developer and DEBUG=0 picks release builds.
+//
+// the macro PRINT_LEVEL_DEV is a filter for DBG messages in developer builds.
+// When PRINT_LEVEL_DEV is set to kLlLog, DBG messages are not printed.
+//
+// Instantiated object c_logInfo, of class LogInfo, provides finer control of
+// the logging behavior during execution.  Use emitLogDevice() to change the
+// message destination.  Use setLogMode() to change the verbosity of the messages.
+//
+// In the case of DBG and LOG, the message needs to print the name of the SW
+// component as the volume of messages can be huge.  Use enum LOG_TAGS to define
+// the component ID and its name string.
+//
+// Since INFO, WARN, ERR and FATAL are for general consumption, each message
+// should provide an number code under enum LogNumberCode.
+//
+// Following are usage of logging actions supported:
+//
+// GDB,LOG,INFO,WARN,ERR,FATAL can be invoked as method.
+//   parameters:
+//     TAG
+//     formatted string
+//     variadic list
+//
+// CHECK,DCHECK,CHECK_FATAL,ASSERT also can be invoked as method.
+//   parameters:
+//     condition
+//     formatted string
+//     variadic list
+//
+// Each of the above are mapped to one of the following 3 methods in class LogInfo:
+//
+// EmitLogForDev() - for DBG and LOG
+//
+// EmitLogForUser() - for INFO, WARN, ERR and FATAL
+//
+// EmitErrorMessage() - for CHECK, DCHECK, CHECK_FATAL and ASSERT
+//
+// DBG and LOG send their messages to stdout, and provide additional date and time
+// information.  For the rest, the messages are sent to stderr.
+//
+// In debugging the program, the developer can set breakpoint in one of the above
+// 3 methods depending on the type of message. For ASSERT, abort() is called
+// instead of exit(1) so that the program will not completely exit, to allow the
+// developer to print stack trace and peruse the program environment at the point
+// of the assertion.

+// B. Build Call Graph.

+//    ii) Analysis each function in this module. For each call statement
+//        create a CGNode, and collect potential callee functions to
+//        generate Call Graph.
+// C. Find All Root Node for the Call Graph.
+// D. Construct SCC based on Tarjan Algorithm
+// E. Set compilation order as the bottom-up order of callgraph. So callee
+//    is always compiled before caller. This benefits those optimizations

+// Class Hierarchy Analysis
+// This phase is a foundation phase of compilation. This phase build
+// the class hierarchy for both this module and all modules it depends
+// on. So many phases rely on this phase's analysis result, such as
+// call graph, ssa and so on.
+// The main procedure shows as following.
+// A. Based on the information read from mplts, it collects all class that
+//    declared in modules. And creates a Klass for each class.
+// B. Fill class method info. Connect superclass<->subclass and
+//    interface->implementation edges.
+// C. Tag All Throwable class and its child class.
+// D. In the case of "class C implements B; interface B extends A;",
+//    we need to add a link between C and A. So we recursively traverse
+//    Klass and collect all interfaces it implements.
+// E. Topological Sort
+// F. Based on Topological Sort Order, for each virtual method in a class,
+//    we collect all its potential implementation. If the number of
+//    potential implementations is 1, it means all virtual calls to this
+//    method can be easily devirtualized.
