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).
* Case study: How does the ARM Compiler support unaligned accesses?

Update mscorlib facade to use the rewritten S.P.CoreLib
Indirectly we were building the mscorlib facade against the
pre-rewritten S.P.CoreLib which had more types in it that weren't
present after we rewrote the assembly. This change forces the
TargetPath to be the final output for S.P.CoreLib so the ProjectReference
pulls in the correct assembly and will give errors if there are
missing types when generating the facade.
ICloneable and and ResolveEventHandler were missing so including
those in the model.xml file.

But whenever CI is running and mounting a device, It will check the device is already mounted.

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.

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 silent bad codegen in signed comparison
While working on dotnet/coreclr#5956, I uncovered a silent bad codegen bug in signed
comparison. The way the code was written, we'd do an unsigned set after a
signed compare/jump from the high comparison. However, in this case, we
need to make sure that we are honoring the sign of the comparison done on
the high part of the operation, and the lo comparison would still want to
be an unsigned compare followed by an unsigned set. This change splits
comparisons into two cases: 1) A signed comparison where we have two jumps
for the high part (GT_GT, GT_LT, GT_GE, and GT_LE), which require a signed
set if the high comparisons are true, and an unsigned set if not, and 2)
An unsigned comparison, or a comparison where the sign does not matter for
the compare (GT_NE, GT_EQ), which just require an unsigned set for both
the high and lo operations (the code we already had in genCompareLong).
When we compare longs, we don't need to have both a jg/ja and a jne
instruction for the hi compare for the case where we enregister the result
of the compare, since the set will do the right thing. We only need to
check the lo halves if the hi halves were equal.
For long compares where the result isn't stored in a register, we need to use
signed jumps for the high comparison, and unsigned jumps for the low compare.
Currently, we generate a signed jump in the code for GT_JTRUE that is used by
both compares. This change modifies the logic for these compares/JTRUEs.
We separate the logic into genJTrueLong. In genJTrueLong, we use similar
logic as the legacy backend for the jumps, using a signed jump after the
high compare when we have signed operands, and unsigned jump when we have
a unsigned operands, and an unsigned jump for the low compare.
This change also modifies genJumpKindsForTreeLongHi, since it is now only
used for the uncontained case, where we need to jump to the bbJumpDest if
the compare is true, so we need to use the actual jump type, rather than
just checking for inequality (as inequality only tells us if we need to
check the low halves, not if the condition is true or not).
This change also adds test cases for the two silent bad codegen cases this
commit fixes.
