Massage code for clang-format

This change starts the process of updating the jit code to make it ready
for being formatted by clang-format. Changes mostly include reflowing
comments that go past our column limit and moving comments around ifdefs
so clang-format does not modify the indentation. Additionally, some
header files are manually reformatted for pointer alignment and marked
as clang-format off so that we do not lose the current formatting.

Geunsik Lim [Tue, 26 Jul 2016 03:59:47 +0000 (12:59 +0900)]
Linux/ARM: Fix +3000 bus errors of unit-test in case of O2/O3 levels (dotnet/coreclr#6379)

**PROBLEM**
This patch is to resolve +3000 bus errors that are generated whenever we use
the aggressive optimization levels of clang (issue dotnet/coreclr#5844 ).

When we enable the -O3 optimization level of the clang version(from clang 3.5
to clang 3.9(snapshot)), we have always got the lots of bus errors from the
coreCLR's unit tests. Actually, we can easily monitor SIGBUS signals (e.g.,
"misaligned memory access") with /proc/cpu/alignment facility in kernel space.
Using "echo 2 > /proc/cpu/alignment" makes Linux kernel fixes the problems
but the performance of the application will be degraded.
.source: http://lxr.free-electrons.com/source/Documentation/arm/mem_alignment

**VERSION 4**
. Use 'GET_UNALIGNED_VALXXX' macros in the CoreClr infra-structure without
  any need for ifdefs.

**VERSION 3**
.Apply this PR on only Linux/ARM for different system environment (Windows).

Here is .NET CI Report on Windows: Compile Error
error C2146: syntax error: missing ';' before identifier '__unaligned_int32'
(compiling source file D:\j\workspace\checked_windo---f6dc6fe4\src\jit\alloc.cpp)
[D:\j\workspace\checked_windo---f6dc6fe4\bin\obj\Windows_NT.x64.Checked\src\jit\
crossgen\clrjit_crossgen.vcxproj] Indication 1

**VERSION 2**
.Add UNALIGNED_ARM macro for handling ARM core specific optimization levels.
.Add RISC-based ARM core handling into the existing infra-structure of the
platform adaptation layer (PAL) for aggressive optimization cases on Linux/ARM.

**VERSION 1**
Basically, RISC-based ARM architecture requires aligned access with 4byte reads.
In order to support aggressive optimization levels such as O2/O3, let's use
attribute keyword of aligned(1) instead of using memcpy(2) in into
a properly aligned buffer or the packing attribute.

**BACKGROUND**
According to ARM information center(infocenter.arm.com), By default,
the ARM compiler expects normal C and C++ pointers to point
to an aligned word in memory. A type qualifier __packed is provided to
enable unaligned pointer access. If you want to define a pointer to a word
that can be at any address (that is, that can be at a non-natural alignment),
you must specify this using the __packed qualifier when defining the pointer:
__packed int *pi; // pointer to unaligned int

However, clang/llvm does not support the __packed qualifier such as
__attribute__((packed)) or __attribute__((packed, aligned(4)))

In -O0 (debug build) the innermost block is emitted as the following assembly,
which works properly:
 ldr r1, [r0, dotnet/coreclr#24]
 ldr r2, [r0, dotnet/coreclr#20]

In -O3 (release build) however the compiler realizes these fields are adjacent
and generates this assembly:
 ldrdeq  r2, r3, [r0, dotnet/coreclr#20]
Unfortunately, vldr/ldrdb instructions always generate an alignment fault
(in practice). It seems that clang uses ldrb instruction although GCC uses
ldr instruction because armv7 supports unaligned ldr instruction.

Note: If some arm architectures (e.g., Linux/ARM Emulator) does not support
unaligned ldr, this issue is not generated with aggressive optimization
levels (e.g., -O2 and -O3).

8 years agoJit: fix issues with optMethodFlags
Andy Ayers [Thu, 21 Jul 2016 07:34:25 +0000 (00:34 -0700)]
Jit: fix issues with optMethodFlags

Closes dotnet/coreclr#6368.

optMethodFlags is a member field of the Compiler object. It is used
during importation to flag IR that might benefit from earlyProp, and
used in earlyProp to skip execution if nothing is flagged. However,
there were a number of issues with the implementation.

First, the value was never initialized. So in CHK/DBG builds, it would
get set to 0xFFFFFFFF by the default allocator fill. In RELEASE builds
the value would be randomly set. This randomness could easily lead to
nondeterministic codegen in RELEASE. More on this subsequently.

Second, the value was not propagated during inlining. So if interesting
constructs only entered the root method via inlines, they potentially
might not trigger earlyProp.

Third, not all interesting constructs were flagged.

The JIT ORs flag values into optMethodFlags as it imports constructs
that should trigger earlyProp. It also re-uses the same compiler instance
in most cases. So, relatively quickly, even in release, all the relevant
flags end up set and earlyProp will always be run. Hence the window
for observing the nondeterministic is was limited to the first few
methods jitted by each compiler instance.

So to sum up: in DBG/CHK, early prop always runs, regardless of need.
In RELEASE, it runs unpredictably for the first few methods, then always
runs, regardless of need.

To see the nondeterminism in RELEASE, early methods would have to be free
of interesting constructs but pull them in via inlining (or contain
interesting constructs not currently flagged as such during importation).
This set of circumstances is evidently rare enough that the nondeterminism
has not been noted. Also, it is quite unlikely to lead to bad codegen,
just missed opportunities.

We might have caught this if we had reliable RELEASE/CHK diffing ready;
see for instance dotnet/coreclr#5063.

The fix is to initialize optMethodFlags to zero in compInit, and merge in
the inlinee's copy during fgInsertInlineeBlocks. Logging tracks when the
inlinee's copy causes a flag update.

This was tricky to test for diffs because in CHK all that should happen is
that we run earlyProp less often. So any diff in CHK is a missed case of
flagging during importation. I found once such case via SPMI where the array
index is a constant, and added constant indices to the flagging set.

Because I also set the block flag, this both caused earlyProp to run
and also look at that block; the latter has triggered a fair number of
diffs, almost all of them beneficial (0.42% improvement in SPMI), winners
outnumber losers by about 50:1.

A typical example of a diff is that the null check below is removed.

```asm
       mov      rcx, qword ptr [(reloc)]
       mov      edx, 4
       call     CORINFO_HELP_NEWARR_1_VC
**     mov      edx, dword ptr [rax+8]
       mov      byte  ptr [rax+16], 255
       mov      byte  ptr [rax+17], 254
```

With this change in place, earlyProp how runs selectively based on need in
all configurations. We're still running earlyProp in all the cases where it
can make a difference, and finding more improvements when it does run, but
we're not running it in cases where it can't.

8 years agoGCInfo: Support versioning.
Swaroop Sridhar [Fri, 15 Jul 2016 07:41:30 +0000 (00:41 -0700)]
GCInfo: Support versioning.

This change enables the VM to support multiple versions GCInfo concurrently.
This is necessary in light of upcoming work to add ReturnType and other
modifications to the GCInfo format -- so that existing ReadyToRun images
will continue to run correctly.

The version# is not stored in the GcInfo structure -- because it is
wasteful to store the version once for every method. Instead, it is
tracked per range-section of generated/loaded methods.

The GCInfo version is computed as:
1) The current GCINFO_VERSION for JITted and Ngened images
2) A function of the Ready-to-run major version stored in READYTORUN_HEADER
   for ready-to-run images. ReadyToRunJitManager::JitTokenToGCInfoVersion()
   provides the GcInfo version for any Method. Currently, there's only one
   version of GCInfo.

An abstraction GCInfoToken is added to the GcInfo interface, which tracks the
{GcInfo, Version} pair in-memory. Several GcInfo APIs are
modified to use GCInfoToken in place of GcInfo pointers.

Notes:
1) SOS GcDump: The GCDump API has separate dump routines for Header and the
pointer-liveness information (DumpGCTable and DumpGCHeader) each of which
advance a pointer to the GCInfo block. These APIs are not changed to
recieve a GCInfoToken in place of the GcInfo block pointer. Instead, they
recieve the GcInfo version at the time of construction.
2) Some routines that are specific to x86 gcInfo (ex: crackMethodInfoHdr)
are not yet updated to use versioning, since the development plan is to
update the Non-x86 GcInfo structure first.
3) The x86 specific structs defining GcInfo headers are moved to GcInfoTypes.h,
along with the non-x86 GcInfo type definitions.

Fix is_blittable partial specializations (dotnet/coreclr#6357)

The is_blittable partial specializations were defined using "class", privately
inheriting from std::true_type. This means the ::value member variable will
be inaccessible to most users of these types. Thus the type
``std::enable_if<is_blittable<T>::value>::type'' will always result in a
substitution failure with a compiler that respects accessibility in SFINAE.

This commit changes "class" to "struct" for these partial specializations
so they inherit publicly from std::true_type.
