`llvm-bcanalyzer` prints out the stream type of the file it is

a stream type of "LLVM IR". However, any other bitstream format is

Add some checks for two other common bitstream formats: Clang AST

begin with 'DIAG'.

[PowerPC] fix incorrect vectorization of abs() on POWER9
Vectorized loops with abs() returns incorrect results on POWER9. This patch fixes it.
For example the following code returns negative result if input values are negative though it sums up the absolute value of the inputs.
int vpx_satd_c(const int16_t *coeff, int length) {
int satd = 0;
for (int i = 0; i < length; ++i) satd += abs(coeff[i]);
return satd;
}
This problem causes test failures for libvpx.
For vector absolute and vector absolute difference on POWER9, LLVM generates VABSDUW (Vector Absolute Difference Unsigned Word) instruction or variants.
Since these instructions are for unsigned integers, we need adjustment for signed integers.
For abs(sub(a, b)), we generate VABSDUW(a+0x80000000, b+0x80000000). Otherwise, abs(sub(-1, 0)) returns 0xFFFFFFFF(=-1) instead of 1. For abs(a), we generate VABSDUW(a+0x80000000, 0x80000000).

for functionality and performance comparison tests (and mostly for
-hwasan-mapping-offset=0 case).
The implementation is stripped down ASan one, picking only the relevant
parts in the following assumptions: shadow scale is fixed, the shadow
memory is dynamic, it is accessed via ifunc global, shadow memory address
rematerialization is suppressed.
Keep zero-based shadow memory for kernel (-hwasan-kernel option) and
calls instreumented case (-hwasan-instrument-with-calls option), which
essentially means that the generated code is not changed in these cases.

[X86] WaitPKG instructions
Three new instructions:
umonitor - Sets up a linear address range to be
monitored by hardware and activates the monitor.
The address range should be a writeback memory
caching type.
umwait - A hint that allows the processor to
stop instruction execution and enter an
implementation-dependent optimized state
until occurrence of a class of events.
tpause - Directs the processor to enter an
implementation-dependent optimized state
until the TSC reaches the value in EDX:EAX.
Also modifying the description of the mfence
instruction, as the rep prefix (0xF3) was allowed
before, which would conflict with umonitor during
disassembly.
Before:
$ echo 0xf3,0x0f,0xae,0xf0 | llvm-mc -disassemble
.text
mfence
After:
$ echo 0xf3,0x0f,0xae,0xf0 | llvm-mc -disassemble

[DAGCombine] (float)((int) f) --> ftrunc (PR36617)
This was originally committed at rL328921 and reverted at rL329920 to
investigate failures in Chrome. This time I've added to the ReleaseNotes
to warn users of the potential of exposing UB and let me repeat that
here for more exposure:
Optimization of floating-point casts is improved. This may cause surprising
results for code that is relying on undefined behavior. Code sanitizers can
be used to detect affected patterns such as this:
int main() {
float x =
4294967296.0f;
x = (float)((int)x);
printf("junk in the ftrunc: %f\n", x);
return 0;
}
$ clang -O1 ftrunc.c -fsanitize=undefined ; ./a.out
ftrunc.c:5:15: runtime error: 4.29497e+09 is outside the range of
representable values of type 'int'
junk in the ftrunc: 0.000000
Original commit message:
fptosi / fptoui round towards zero, and that's the same behavior as ISD::FTRUNC,
so replace a pair of casts with the equivalent node. We don't have to account for
special cases (NaN, INF) because out-of-range casts are undefined.

This patch adds the ability for the ObjectYAML DWARFEmitter to calculate

in the Compile Unit header.
The DIEFixupVisitor can be extended in the future to enable more complex
fix ups which will enable simplified YAML string representations.
This is also very useful when using the YAML format in unit tests
because you no longer need to know the length of the compile unit when
writing the YAML string.

can be wrong, and those are only generated by SDIVcc. Verification on
hardware shows that simply replacing SDIV with SDIVcc does not avoid
the bug with negative operands.
This reverts r283727.

[Sparc] Use synthetic instruction clr to zero register instead of sethi
Using `clr reg`/`mov %g0, reg`/`or %g0, %g0, reg` to zero a register

[AArch64][AsmParser] Extend RegOp with integrated 'shift/extend'.
Summary:
In some cases the shift/extend needs to be explicitly parsed together
with the register, rather than as a separate operand. This is needed
for addressing modes where the instruction as a whole dictates the
scaling/extend, rather than specific bits in the instruction.
By parsing them as a single operand, we avoid the need to pass an
extra operand in all CodeGen patterns (because all operands need to
have an associated value), and we avoid the need to update TableGen to
accept operands that have no associated bits in the instruction.
An added benefit of parsing them together is that the assembler
can give a sensible diagnostic if the scaling is not correct.
This is patch [2/4] in a series to add assembler/disassembler support for
SVE's contiguous LD1 (scalar+scalar) instructions:

AMDGPU: Legalize the operand of SI_INIT_M0
Summary:
This fixes a case where the argument to a sendmsg intrinsic
ends up in a VGPR, for whatever reason.
The underlying performance issue is that a multiplication that
can be an s_mul_i32 is instead needlessly generated as
v_mul_u32_u24, but this is not addressed by this patch.

[Sparc] Fix addressing mode when using 64-bit values in inline assembly
Summary:
If a 64-bit register is used as an operand in inline assembly together
with a memory reference, the memory addressing will be wrong. The
addressing will be a single reg, instead of reg+reg or reg+imm. This
will generate a bad offset value or an exception in printMemOperand().
For example:
```
long long int val = 5;
long long int mem;
__asm__ volatile ("std %1, %0":"=m"(mem):"r"(val));
```
becomes:
```
std %i0, [%i2+589833]
```
The problem is that SelectInlineAsmMemoryOperand() is never called for
the memory references if one of the operands is a 64-bit register.
By calling SelectInlineAsmMemoryOperands() in tryInlineAsm() the Sparc
version of SelectInlineAsmMemoryOperand() gets called for each memory
reference.

LowerTypeTests: Propagate symver directives

This change fixes https://crbug.com/834474, a build failure caused by
LowerTypeTests not preserving .symver symbol versioning directives for
exported functions. Emit symver information to ThinLTO summary data and
then propagate symver directives for exported functions to the merged
module.
Emitting symver information to the summaries increases the size of
intermediate build artifacts for a Chromium build by less than 0.2%.
