When `FileAction` opens file with write access, it doesn't clear the
file nor append to the end of the file if it already exists. Instead, it
writes from cursor index 0.
For example, by using the settings `target.output-path` and
`target.error-path`, lldb will redirect process stdout/stderr to files.
It then calls this function to write to the files which the above
symptoms appear.
## Test
- Added unit test checking the file flags
- Added 2 api tests checking
- File content overwritten if the file path already exists
- Stdout and stderr redirection to the same file doesn't change its
behavior
Code cleanups for TableGen files, changes includes function names,
variable names and unused imports.

_TIED and _MASK_TIED pseudos have one less operand compared to other
pseudos, thus we shouldn't attach the same number of SchedRead for these
instructions.
I don't think we have a way to (explicitly) check scheduling classes. So
I only test this patch with existing tests.
add a unique and a sort option to the update_mc_test_check script.
These mc asm/dasm files are usually large in number of lines, and these
lines are mostly similar to each other. These options can be useful when
maintainer is merging or resolving conflicts by making the file
identifical
Also fixed a small issue in asm/dasm such that the auto generated header
line is
1. asm using ";" instead of "//" as comment marker
2. dasm using ";" instead of "#" as comment marker
If we have a minimum vlen, we were adjusting StackSize to change the
unit from vscale to bytes, and then calculating the required padding
size for alignment in bytes. However, we then used that padding size as
an offset in vscale units, resulting in misplaced stack objects.
While it would be possible to adjust the object offsets by dividing
AlignmentPadding by ST.getRealMinVLen() / RISCV::RVVBitsPerBlock, we can
simplify the calculation a bit if instead we adjust the alignment to be
in vscale units.
@topperc This fixes a bug I am seeing after #110312, but I am not 100%
certain I am understanding the code correctly, could you please see if
this makes sense to you?
Implement TrieRawHashMap can be used to store object with its associated
hash. User needs to supply a strong hashing function to guarantee the
uniqueness of the hash of the objects to be inserted. A hash collision
is not supported and will lead to error or failed to insert.
TrieRawHashMap is thread-safe and lock-free and can be used as
foundation data structure to implement a content addressible storage.
TrieRawHashMap owns the data stored in it and is designed to be:
* Fast to lookup.
* Fast to "insert" if the data has already been inserted.
* Can be used without lock and doesn't require any knowledge of the
participating threads or extra coordination between threads.
It is not currently designed to be used to insert unique new data with
high contention, due to the limitation on the memory allocator.
Fix bug that `mir-strip-debug` pass does not remove debug location from
bundled instructions.
Problem arises during testing that debug info does not affect
optimization passes output (`llvm-lit` with ` -Dllc="llc
-debugify-and-strip-all-safe"`), when pass operates on MIR with bundled
instructions + memory operands.
Let mir test check looks like:
```
CHECK-NEXT: BUNDLE {
CHECK-NEXT: $r3 = LD $r1, $r2 :: (load (s64) from %ir.a, !tbaa !2)
CHECK-NEXT: }
```
So as `mir-strip-debug` pass does not process bundled instructions,
running `llc -debugify-and-strip-all-safe` on the test will produce the
following output:
```
BUNDLE {
$r3 = LD $r1, $r2, debug-location !DILocation(line: 3, column: 1, scope: <0x608cb2b99b10>) :: (load (s64) from %ir.a, !tbaa !2)
}
```
And test will fail, but it shouldn't.
Seems like the root cause is that `mir-strip-debug` pass should remove
debug location from bundled instructions.

This patch adds assembly/disassembly for the following instructions:
FMMLA (widening, FP16 to FP32)
FMMLA (widening, FP8 to FP16)
FMMLA (widening, FP8 to FP32)
According to [1]

Only accumulate the codesize increase of functions that are actually
specialized, rather than for every candidate specialization that we
analyse.
This fixes a subtle bug where prior analysis of candidate
specializations that were deemed unprofitable could prevent subsequent
profitable candidates from being recognised.
Enable specialization on literal constant arguments by default in
Function Specialization.

This adds the `llvm.sincos` intrinsic, legalization, and lowering.
The `llvm.sincos` intrinsic takes a floating-point value and returns
both the sine and cosine (as a struct).
```
declare { float, float } @llvm.sincos.f32(float %Val)
declare { double, double } @llvm.sincos.f64(double %Val)
declare { x86_fp80, x86_fp80 } @llvm.sincos.f80(x86_fp80 %Val)
declare { fp128, fp128 } @llvm.sincos.f128(fp128 %Val)
declare { ppc_fp128, ppc_fp128 } @llvm.sincos.ppcf128(ppc_fp128 %Val)
declare { <4 x float>, <4 x float> } @llvm.sincos.v4f32(<4 x float> %Val)
```
The lowering is built on top of the existing FSINCOS ISD node, with
additional type legalization to allow for f16, f128, and vector values.
Fixes#62899
In this commit I have updated the list of options
to include any missing options and re-rordered
some of them to match the order in lit's --help.
Where there was a larger description in this document
I've used that instead of the --help description.
This *does not* include --use-unique-output-file-name
as this was only added recently and we are still
debating whether it will be kept.
AMD has it's own implementation of vector calls.
New vector calls are introduced in the library for exp10, log10, sincos and finite asin/acos

I received a report that the outliner drops memoperands and causes this
code to crash. Handle this by only copying the memoperand if it exists.
