NAS-140023 / 26.0.0-BETA.1 / Fix system version regex for apps min max version validation (#18314)
This commit fixes an issue where the SCALE version format changed from
XX.XX (25.04) to XX.X (26.0), breaking the version regex which required
exactly 2 digits after the first dot. This caused all catalog app
installs to fail on 26.x builds.
[AMDGPU] Remove extra pipes from load-saddr-offset-imm.ll (#183874)
This test uses opt to run instcombin and then pipes that into llc which
has its output piped into FileCheck. Before this patch, the test also
piped in the source file into llc as well, which caused issues with a
downstream test executor that executes the lines in bash. However, these
extra pipes don't make sense anyways, so remove them.
[clang] NFC: remove unused / untested workaround in pack deduction
This snippet was part of what was introduced in 130cc445e46836b28defdce03b1adfdb16ddcf41
However, none of the existing tests require it, including the tests added in
that commit.
One of those tests had a FIXME which was fixed when we switched
frelaxed-template-template-args on by default as well.
[CUDA] Allow `extern __shared__` on non-array types
NVCC allows `extern __shared__` on any type, not just incomplete arrays.
This is commonly used in CUDA libraries like NCCL to overlay a struct on
dynamically-allocated shared memory:
extern __shared__ ncclShmemData ncclShmem;
Previously, Clang rejected this with a hard error and did not add
`CUDASharedAttr` to the VarDecl. This caused a cascade: `IdentifyTarget()`
classified the variable as host-side, and any device code referencing it
got a spurious "reference to __host__ variable in __device__ function"
error.
Downgrade the error to a default-ignored warning (`-Wcuda-extern-shared`)
and always add `CUDASharedAttr` so the variable is correctly classified as
device-side. The old `err_cuda_extern_shared` is preserved for potential
future use.
[AMDGPU][SIInsertWaitcnts] Move VCCZ workaround code out of the way (#182619)
This is a cleanup patch that moves the VCCZ specific workaround code
from `SIInsertWaitcnts::insertWaitcntInBlock()` to a separate class and
refactors it a bit to make it easier to read.
The end result is a simpler `insertWaitcntInBlock()`.
Should be NFC.
skip fc.fc_hosts when writing empty scst.conf config
For hygiene reasons we now write an empty config on the STANDBY
node after SCST has been stopped. Avoid further fc calls in this
situation (could reload a kernel module).
[CIR][NFC] Move some builtin tests to the CodeGenBuitins folder (#183607)
This moves a few tests that were created in the wrong location. Also
changes the names of some test files to maintain consistency.
Fix profile metadata propagation in InstCombine select folding
Propagate profile metadata when folding select instructions with logical AND/OR conditions and when canonicalizing SPF to intrinsics. This fixes profile verification failures in Transforms/InstCombine/select-and-or.ll.
[SLP]Fix operand reordering when estimating profitability of operands
Need to swap operand for a single instruction, not for the the same lane
of the first and second instruction in the list
[CMake] Propagate dependencies to OBJECT libraries in `add_llvm_library` (#183541)
Previously, transitively inherited calls to
`target_include_directories(foo SYSTEM ...)` were being squashed into a
flat list of includes, effectively stripping off `-isystem` and
unintentionally forwarding warnings from such dependencies.
To correctly propagate `SYSTEM` dependencies, use
`target_link_libraries` to forward the parent target's link dependencies
to the OBJECT library (similar to the `_static` flow below). Unlike a
flat `target_include_directories`, this lets CMake resolve transitive
SYSTEM include directories through the proper dependency chain.
Note that `target_link_libraries` on an OBJECT library propagates all
usage requirements, not just includes. This also brings in transitive
`INTERFACE_COMPILE_DEFINITIONS`, `INTERFACE_COMPILE_OPTIONS`, and
`INTERFACE_COMPILE_FEATURES`. This is arguably more correct, as the
OBJECT library compiles the same sources and should see the same flags.
