Reapply "[BOLT][BTI] Skip inlining BasicBlocks containing indirect tailcalls" (#169881)
This reverts commit 9bffb10e8b77b00033f2e997731193f81676cd60.
Fix: added assertions to the requirements of the test
--------
Original commit message:
In the Inliner pass, tailcalls are converted to calls in the inlined
BasicBlock. If the tailcall is indirect, the `BR` is converted to `BLR`.
These instructions require different BTI landing pads at their targets.
As the targets of indirect tailcalls are unknown, inlining such blocks
is unsound for BTI: they should be skipped instead.
[lldb-dap] Add data breakpoints for bytes (#167237)
This patch adds support for `dataBreakpointInfoBytes` capability from
DAP. You can test this feature in VSCode (`Add data breakpoint at
address` button in breakpoints tab).
[AArch64] Fix throughout of 64-bit SVE gather loads (#168572)
In the Neoverse N3 Software Optimisation Guide, SVE non termporal gather
load, vector+scalar 64-bit element size and gather load, vector + imm,
64-bit element size both show throughput of 4/5. However, it currently
shows as 2/3. This patch adds a new resource group in order to show the
correct throughput.
[libc] Add clock_gettime for Darwin (#167160)
This patch adds support for clock_gettime for Darwin. Darwin syscall
'gettimeofday' is used to query the time from the system.
Many headers in llvm-libc-types, namely clockid_t, struct_timespec,
struct_timeval, suseconds_t, time_t_32, time_t_64, are modified to
include
header guards as Darwin has its own implementation of primitive types.
[flang][OpenMP] Make OmpDirectiveSpecification::Flags an EnumSet (#169713)
The idea is that there can be multiple flags on a given directive. When
"Flags" was a simple enum, only one flag could have been set at a time.
[NFC] Remove deprecated Argument::getParamAlignment() declaration (#169911)
The implementation of Argument::getParamAlignment() was removed in
commit b55f83d013eff244f7cf6bfcd06f06f7c894ff28, but the declaration in
Argument.h was left behind. Remove it.
NFC.
[libc][test] split exit tests into two separate tests (#169820)
_Exit(3) is a fairly simple syscall wrapper whereas exit(3) calls
atexit-registered functions + whole lot of stuff that require support
for sync primitives.
Splitting the tests allows testing the former easily (especially for new
port projects)

[flang][OpenMP] Add lowering of subroutine calls in custom reduction combiners (#169808)
This patch adds support for lowering subroutine calls in custom
reduction combiners to MLIR.
[LLDB][PDB] Access object file through module (#169728)
When a PDB is loaded through `target symbols add <pdb-path>`, its
`m_objectfile_sp` is an `ObjectFilePDB` instead of `ObjectFilePECOFF`
(the debugged module). In both the native and DIA plugin, some paths
assumed that `m_objectfile_sp` is the debugged module. With this PR,
they go through `m_objfile_sp->GetModule()->GetObjectFile()`.
For the DIA plugin, this lead to an assertion failure
(https://github.com/llvm/llvm-project/issues/169628#issuecomment-3582555277)
and for both plugins, it meant that the symbol table wasn't loaded.
AMDGPU/GlobalISel: Report RegBankLegalize errors using reportGISelFailure
Use standard GlobalISel error reporting with reportGISelFailure
and pass returning false instead of llvm_unreachable.
Also enables -global-isel-abort=0 or 2 for -global-isel -new-reg-bank-select.
Note: new-reg-bank-select with abort 0 or 2 runs LCSSA,
while "intended use" without abort or with abort 1 does not run LCSSA.
GlobalISel: Stop using TPC to check if GlobalISelAbort is enabled
New pass manager does not use TargetPassConfig.
GlobalISel requires TargetPassConfig to reportGISelFailure,
and it only actual use is to check if GlobalISelAbort is enabled.
TargetPassConfig uses TargetMachine to check if GlobalISelAbort is
enabled, but TargetMachine is also available from MachineFunction.
[AArch64] Fix metrics of ASIMD instructions in Neoverse N3 (#169790)
Some ASIMD instructions in the Neoverse N3 scheduler model seem to have
been missed and have default definitions, which give them incorrect
latency and throughput. This patch fixes such instructions to match the
current N3 SWOG.
