[libc++] Revert recent changes to __hash_table and ext/hash_map (#189427)
This reverts commits 30084d74765c and 5b8c17580482. The second commit
was landed without proper review: not by fault of the submitter, but
because I mistakenly thought this was modifying something else entirely
that is unsupported. The first commit must also be reverted because it
is a breaking change without the second commit.
This corresponds to PRs #183223 and #188660, see those for more details.
libkvm _kvm_ureadm: fix an integer overflow
this has been broken since the initial uvm supporT in 1998.
I suppose it was rare to use >2GB swap in that era.
[ELF] Optimize binary search in getSectionPiece (#187916)
Two optimizations to make getSectionPiece O(1) for common cases:
1. For non-string fixed-size merge sections, use direct computation
(offset / entsize) instead of binary search.
2. Pre-resolve piece indices for non-section Defined symbols during
splitSections. The piece index and intra-piece offset are packed
into Defined::value as ((pieceIdx+1) << 32) | intraPieceOffset,
replacing repeated binary searches (MarkLive, includeInSymtab,
getRelocTargetVA) with a single upfront resolution.
On x86-64, references to mergeable strings use local labels:
leaq .LC0(%rip), %rax # R_X86_64_PC32 .LC0-4
The relocations use non-section symbols and benefit from optimization 2.
On many other targets (e.g. AArch64), the addend is 0 and the assembler

[AArch64] Support TLS variables in debug info (#146572)
This adds an implementation of getDebugThreadLocalSymbol for AArch64 by
using AArch::S_DTPREL.
Fixes #83466
[LLD][AArch64] Handle R_AARCH64_TLS_DTPREL64 in non-alloc sections (#183962)
Clang plan to emit R_AARCH64_TLS_DTPREL64 in .debug_info (see PR
#146572). LLD currently fails to recognize this relocation.
This prevent the debugger from correctly locating TLS variables when
using the DWARF DW_OP_GNU_push_tls_address or DW_AT_location with DTPREL
offsets.
This patch adds support for R_AARCH64_TLS_DTPREL64, adds its mapping to
R_DTPREL.

[X86][APX] Remove NF entries in X86CompressEVEXTable (#189308)
NF (No-Flags) instructions should not compress to non-NF instructions,
as this would incorrectly modify flags behavior. The compression table
is only intended for encoding optimizations that preserve semantics.
This removes the incorrect NF entries that could have led to
miscompilation if the compression logic were applied.
nfs_nfsdserv.c: Fix handling of archive flag for mkdir
An NFSv4.1/4.2 client can set/clear the archive, hidden
and system flags when creating non-regular files, such
as directories.
Without this patch, the setting of va_flags causes an
EPERM failure, since they are specified for VOP_MKDIR(),
VOP_MKNOD() and VOP_SYMLINK().
This patch sets va_flags == VNOVAL for the above VOP_xxx()
calls and then sets/clears the flags after creation,
which fixes the problem.
This bug only affects the Windows NFSv4.1/4.2 client.

[CodeGenPrepare][NFC] Reland: Update the dominator tree instead of rebuilding it (#179040)
The original differential revision is https://reviews.llvm.org/D153638
Reverted in
https://github.com/llvm/llvm-project/commit/f5b5a30858f32e237636acd296b6d0f87c1dfe97
because of causing a clang crash.
This patch relands it with the crash fixed. Call `DTU->flush()` in each
iteration of `while (MadeChange)`
loop, flush all awaiting BasicBlocks deletion, and prevent iterator
invalidation.
[RISCV] Check hasVInstructions() rather than hasStdExtZbb() for UMAX/UMIN/SMAX/SMIN combines. (#189506)
The combines are related to combining min/max with vector reductions. I
don't think it matters if Zbb is enabled.
I did not merge this with other hasVInstructions() because I have a P
extension patch coming after this that will need to separate them.
