[SPARC] Allow overaligned `alloca`s (#107223)

2024-11-03T15:53:03+00:00

SPARC ABI doesn't use stack realignment, so let LLVM know about it in
`SparcFrameLowering`. This has the side effect of making all overaligned
allocations go through `LowerDYNAMIC_STACKALLOC`, so implement the
missing logic there too for overaligned allocations.
This makes the SPARC backend not crash on overaligned `alloca`s and fix
https://github.com/llvm/llvm-project/issues/89569.

[NVPTX] support dynamic allocas with PTX alloca instruction (#84585)

2024-03-15T18:51:46+00:00

Add support for dynamically sized alloca instructions with the PTX
alloca instruction introduced in PTX 7.3 
([9.7.15.3. Stack Manipulation Instructions: alloca]
(https://docs.nvidia.com/cuda/parallel-thread-execution/index.html#stack-manipulation-instructions-alloca))

[CodeGen] Convert some tests to opaque pointers (NFC)

[Sparc] Convert tests to check 'target=sparc.*'

2022-12-01T19:41:30+00:00

Part of the project to eliminate special handling for triples in lit
expressions.

[NVPTX] Convert tests to check 'target=nvptx.*'

2022-12-01T17:01:48+00:00

Part of the project to eliminate special handling for triples in lit
expressions.

[NVPTX][tests] add "XFAIL: nvptx" for some tests

2022-04-26T14:26:56+00:00

Some tests failed for NVPTX target, but it seems that NVPTX will be
fixed and the tests will pass. So, just mark the tests as XFAIL

[CodeGen][test] XFAIL CodeGen/Generic/ForceStackAlign.ll on SPARC

2022-02-08T07:57:59+00:00

`CodeGen/Generic/ForceStackAlign.ll` `FAIL`s on SPARC like this:

  LLVM ERROR: Function "g" required stack re-alignment, but LLVM couldn't
handle it (probably because it has a dynamic alloca).

According to the comments in `llvm/lib/Target/Sparc/SparcFrameLowering.cpp`
(`SparcFrameLowering::emitPrologue`) and `SparcRegisterInfo.cpp`
(`SparcRegisterInfo::canRealignStack`) this isn't going to change any time
soon, so this patch `XFAIL`s the test.

Tested on `sparcv9-sun-solaris2.11`.

reland [IR] make -stack-alignment= into a module attr

2021-06-08T17:59:46+00:00

Relands commit 433c8d950cb3a1fa0977355ce0367e8c763a3f13 with fixes for
MIPS.

Similar to D102742, specifying the stack alignment via CodegenOpts means
that this flag gets dropped during LTO, unless the command line is
re-specified as a plugin opt. Instead, encode this information as a
module level attribute so that we don't have to expose this llvm
internal flag when linking the Linux kernel with LTO.

Looks like external dependencies might need a fix:
* https://github.com/llvm-hs/llvm-hs/issues/345
* https://github.com/halide/Halide/issues/6079
