Fangrui Song	b279f6b098	[NVPTX,test] Change llc -march= to -mtriple= ... Similar to 806761a7629df268c8aed49657aeccffa6bca449 -mtriple= specifies the full target triple while -march= merely sets the architecture part of the default target triple (e.g. Windows, macOS), leaving a target triple which may not make sense. Therefore, -march= is error-prone and not recommended for tests without a target triple. The issue has been benign as we recognize nvptx{,64}-apple-darwin as ELF instead of rejecting it outrightly.	2024-12-15 10:45:11 -08:00
Joseph Huber	f4381d4644	[NVPTX] Add initial support for '.alias' in PTX ... This patch adds initial support for using aliases when targeting PTX. We perform a pretty strict conversion from the globals referenced to the expected output. as described in the PTX documentation at https://docs.nvidia.com/cuda/parallel-thread-execution/index.html#kernel-and-function-directives-alias These cannot currently be used due to a bug in the `nvlink` implementation that causes aliases to pruned functions to crash the linker.
