[Instrumentor] Add "conversion" instruction instrumentation support
We now allow to have instrumentation opportunities for many instructions
(=opcodes) to bundle common classes together. Users can use filters on
the opcode, type-id, and size to statically select what they are
interested in.
[clang-format] Add a dependent build target to check-clang-format (#199169)
This makes check-clang-format automatically builds
clang-format-check-format, which checks that the new clang-format
doesn't break the existing format of the clang-format source.
[RISCV] Reserve all sub-registers of user reserved GPRs
When a GPR is reserved by the user (e.g., via `-mattr=+reserve-x27`)
or marked as constant, only the top-level register was being marked
reserved in `RISCVRegisterInfo::getReservedRegs`. Its sub-registers
(`X27_W` and `X27_H`) remained unreserved.
This broke `LiveIntervals` when register pressure tracking was enabled
by #115445. Because the sub-registers were not reserved, the register
unit was considered non-reserved, causing `LiveIntervals` to track its
liveness and crash in the Machine Verifier due to the reserved
register missing from basic block live-in lists.
Instead, we should ensure that reserving a register also reserves all
of its sub-registers, so that the register unit is correctly
identified as reserved and ignored by `LiveIntervals`.
Fixes #176227
[AIX][LLVM] Update the default code model for 64-bit
This changes the default code model on 64-bit to AIX.
For many applications, the existing small code model is simply
inadequate to build. Users often then end up relying on expensive linker
fixups (i.e. -Wl,-bigtoc) to work around the issue when they would have
been better served by moving to the larger code model. Our analysis
and benchmarking leads us to believe this's generally a net benefit to
users.
[lldb] Adjust TestFunctionTypes.py for arm64e (#199295)
Normally the open parens happen right before a.out, but on arm64e the
load address is placed there instead. So instead of:
$0 = 0x0000d00d (a.out...)
we instead have:
$0 = 0xcafed00d (actual=0x0000d00d a.out ...)
Revert "[AArch64] ConditionOptimizer: replace per-block DenseMap with ScopedHashTable traversal (#196746)" (#199288)
This reverts commit 371f57cd67a523d241678509f57d048d58417b87 due to

[libclc] Fix .cl tests in standalone build (#199164)
libclc standalone build puts libclc.bc in ${CMAKE_CURRENT_BINARY_DIR}/
${TARGET_TRIPLE} dir. check-libclc fails because .cl test is looking for
libclc in clang resource dir.
Fix them by adding `--libclc-lib=:{path}` flag for standalone build,
where `path` is path to libclc.bc.
Note: this flag is not used in in-tree build.

Introduce reference counters for SysV semaphores to fix the context
switch use-after-free after tsleep in sys_semget().
sys___semctl() has no such problems, because we do complete reload and
re-check of semaphore stuff, however I like to replace all of them
with the only "semaptr != sema[ix]" check. The semaphore was changed, go
to the beginning of sys___semctl() and acquire it again.
Note, seminfo.semmni only grows, so even if `sema' array was
re-allocated, the sema[ix] is still valid.

[Instrumentor] Improve stub printer (for C/C++ and value packs)
The stub printer now emits a helper header to deal with value packs (in
C and C++). We also make the files C/C++ compatible and use the proper
format strings for int32_t and int64_t.
[Instrumentor] Improve the config wizard script
This makes the config wizard script more generic as we grow
instrumentation opportunities. Better output, e.g., clear paths, are
also displayed now.
Prepared with Claude (AI) and tested by me afterwards.
