libclc: Update remainder
Previously this was failing conformance without -cl-denorms-are-zero
in the float case, and always failing in the double case.
libclc: Implement remainder with remquo
This fixes conformance failures for double and
without -cl-denorms-are-zero. Optimizations are
able to eliminate the unusued quo handling without
duplicating most of the code.
[AsmPrinter] Add generic support for verifying instruction sizes (#187703)
Many backends rely on TII reporting correct instruction sizes for MIR
level branch relaxation passes. Reporting a too small size can result in
MC fixup failures (or silent miscompiles for unvalidated fixups).
Some time ago I added validation to the PPC asm printer to verify that
the TII instruction size matches the actually emitted size. This was
very helpful to systematically fix all incorrectly reported instruction
sizes.
However, the same problem also exists in lots of other backends, so this
moves the validation into AsmPrinter, controlled by a new
getInstSizeVerifyMode() hook in TII, which is disabled by default.
The intention here is to gradually enable this validation for more
backends (which requires fixing them first).
[AMDGPU] Update test to match comment. NFC (#187273)
The comment says there shouldn't be any free registers, so update the
inline assembly to clobber all non-preserved SGPRs.
[clang-tidy] Correctly ignore function templates in derived-method-shadowing-base-method (#185741) (#185875)
This commit fixes a false positive in the
derived-method-shadowin-base-method clang-tidy check, as described in
[ticket 185741](https://github.com/llvm/llvm-project/issues/185741)
Fixes #185741

[BOLT] Remove some unused code (NFC) (#183880)
Remove some unused code in BOLT:
- `RewriteInstance::linkRuntime` is declared but not defined
- `BranchContext` typedef is never used
- `FuncBranchData::getBranch` is defined but never used
- `FuncBranchData::getDirectCallBranch` is defined but never used
Add special handling of TEST_SSH_HOSTBASED_AUTH=setupandrun.
This will MODIFY THE CONFIG OF THE SYSTEM IT IS RUNNING ON to enable
hostbased authentication to/from itself and run the hostbased tests. It
won't undo these changes, so don't do this on a system where this matters.
[X86] Emit user-friendly error for x86_fp80 with x87 disabled on x86_64 (#183932)
When compiling a function that uses `x86_fp80` on x86_64 with x87 disabled (`-mattr=-x87`), LLVM crashes with a cryptic internal error.
Fixes #182450
[flang][FIR] add a new fir.bitcast operation (#187793)
This patch introduces a new bitcast operation for integer, float,
character, and logical.
The main rational for it is that it is currently not possible to express
such bitcast in FIR without going trough memory and there is a need to
have some bitcast support when interfacing with the memref dialect where
one cannot use fir.char<> and fir.logical and must use the underlying
storage type. Using fir.convert is not a good idea because it is a
semantic cast and it will for instance normalize integers when
converting from/to logical.
This could also be used to simplify the implementation of TRANSFER for
the cases of simple scalars of those types.

[clang][Neon] Extract code shared by classic and CIR codegen (NFC) (#186448)
Extract intrinsic maps shared by the classic and CIR codegen into a new
header, AArch64CodeGenUtils.h, which is reused by both. This keeps the
implementations in sync and avoids code duplication.
The maps are moved without modification. The accompanying code (e.g.
`ARMVectorIntrinsicInfo`) is updated to follow Clang coding style
(CamelCase instead of the camelCase used in CIR).
