Prioritize the constructor call of __local_xray_dyninit()
Summary:
For platforms without preinit support (such as NetBSD/amd64) the
initialization routine __xray_init() was called in non-deterministic order
compared to other constructors. This caused breakage failures
as xray routines attempted to execute code with assumption of
being initialized, which was no always true.

as it did not allow to specify this compiler extension.

[XRay] Update XRayRecord to support Custom/Typed Events
Summary:
This change cuts across LLVM and compiler-rt to add support for
rendering custom events in the XRayRecord type, to allow for including
user-provided annotations in the output YAML (as raw bytes).
This work enables us to add custom event and typed event records into
the `llvm::xray::Trace` type for user-provided events. This can then be
programmatically handled through the C++ API and can be included in some
of the tooling as well. For now we support printing the raw data we
encounter in the custom events in the converted output.
Future work will allow us to start interpreting these custom and typed
events through a yet-to-be-defined API for extending the trace analysis
library.

For the guards, it might be too conservative to use this variable, we can
instead use a more precise logic from LoopSafetyInfo. Currently it is only NFC
because `IsMemoryNotModified` is also conservatively set to `false` for all

@Y = global [400 x i16] zeroinitializer, align 1
define i16 @foo() {
entry:
br label %for.body
for.body: ; preds = %entry, %for.body
%i = phi i16 [ 0, %entry ], [ %inc, %for.body ]
%arrayidx = getelementptr inbounds [400 x i16], [400 x i16]* @Y, i16 0, i16 %i
store i16 0, i16* %arrayidx, align 1
%inc = add nuw nsw i16 %i, 1

Fix (and improve) the support for C99 variable length array types
Clang recently improved its DWARF support for C VLA types. The DWARF
now looks like this:
0x00000051: DW_TAG_variable [4]
DW_AT_location( fbreg -32 )
DW_AT_name( "__vla_expr" )
DW_AT_type( {0x000000d3} ( long unsigned int ) )
DW_AT_artificial( true )
...
0x000000da: DW_TAG_array_type [10] *
DW_AT_type( {0x000000cc} ( int ) )
0x000000df: DW_TAG_subrange_type [11]
DW_AT_type( {0x000000e9} ( __ARRAY_SIZE_TYPE__ ) )
DW_AT_count( {0x00000051} )
Without this patch LLDB will naively interpret the DIE offset 0x51 as
the static size of the array, which is clearly wrong. This patch
extends ValueObject::GetNumChildren to query the dynamic properties of
incomplete array types.
See the testcase for an example:
4 int foo(int a) {
5 int vla[a];
6 for (int i = 0; i < a; ++i)
7 vla[i] = i;

[Sanitizers] Disable SANITIZER_CAN_FAST_UNWIND on all SPARC targets
While testing my to-be-submitted Solaris sanitizer support on gcc mainline, I ran into
an issue on Solaris/SPARC (sparc-sun-solaris2.11). Initially libasan.so failed to link:
Undefined first referenced
symbol in file
__sanitizer::BufferedStackTrace::FastUnwindStack(unsigned long, unsigned long, unsigned long, unsigned long, unsigned int) /var/gcc/gcc-9.0.0-
20181024/11.5-gcc-gas/sparc-sun-solaris2.11/./libsanitizer/asan/.libs/libasan.so
This happens because SANITIZER_CAN_FAST_UNWIND is enabled on non-Linux
SPARC targets (cf. sanitizer_stacktrace.h), but the guard around the SPARCv8-only
definition in sanitizer_stacktrace_sparc.cc only works with clang:
clang predefines __sparcv8__ on non-Solaris, and __sparcv8 only on Solaris
gcc predefines __sparcv8 on Solaris, but __sparc_v8__ on non-Solaris
The attached patch allows for all three variants.
However, disabling SANITIZER_CAN_FAST_UNWIND on all SPARC targets
fixes a couple of testsuite failures in the Solaris asan testsuite, so for now it's better
to keep it disabled everywhere.
This allowed the libsanitizer build to complete and gave reasonable (though slightly
worse than on Solaris/x86) testsuite results.

[Sanitizers] Solaris largefile fixes
While testing the Solaris libsanitizer port on GCC mainline, I found that
I'd messed up
the largefile checks in various ways, some of which showed as compile failures
(wrong structure sizes and member offsets), others at runtime, some of those only
on sparc as a big-endian target.
This patch fixes all of them:
- OFF_T is now correctly defined for 32-bit largefile and traditional
environments, and 64-bit.
- The definition of __sanitizer_dirent now checks the correct conditionals.
- sanitizer_procmaps_solaris.cc undefines _FILE_OFFSET_BITS: before
Solaris 11.4 <procfs.h> doesn't even compile with largefile support
enabled, but the use at hand doesn't need it anyway while g++ 9 will
define _FILE_OFFSET_BITS=64 out of the box.
- With full largefile support enabled, one needs to use e.g. mmap64
instead of mmap; this is hidden behind macros.

[MergeICmps] Do not perform the transformation if GEP is used outside of block
Summary:
This patch prevents MergeICmps to performn the transformation if the address operand GEP of the load instruction has a use outside of the load's parent block. Without this patch, compiler crashes with the given test case because the use of `%first.i` is still around when the basic block is erased from https://github.com/llvm-mirror/llvm/blob/master/lib/Transforms/Scalar/MergeICmps.cpp#L620. I think checking `isUsedOutsideOfBlock` with `GEP` is the original intention of the code, as the checking for `LoadI` is already performed in the same function.
This patch is incomplete though, as this makes the pass overly conservative and fails the test `tuple-four-int8.ll`. I believe what needs to be done is checking if GEP has a use outside of block that is not the part of "Comparisons" chain. Submit the patch as of now to prevent compiler crash.

codesize). At -Oz, we can then increase code size by inlining small loops
