It has a lot of diagnostics to catch errorsin PTX, which can be used to verify PTX output from llc.Set -DPXTAS_EXECUTABLE=/path/to/ptxas CMake option to enable it.If this option is not set, then ptxas is substituted to true whicheffectively disables all ptxas RUN lines.LLVM_PTXAS_EXECUTABLE environment variable takes precedence overthe CMake option, and allows to override ptxas executable that is used for LITwithout complete re-configuration.Differential Revision: https://reviews.llvm.org/D121727 List of files: /llvm-project-15.0.7/llvm/test/DebugInfo/NVPTX/debug-name-table.ll Wed, 27 Apr 2022 19:43:55 +0000 Andrew Savonichev <andrew.savonichev@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/DebugInfo/NVPTX/debug-name-table.ll#96e74870 [NVPTX] Fix LIT tests with default nameTableKindDefault nameTableKind results in the following DWARF section: .section .debug_pubnames { .b32 LpubNames_end0-LpubNames_start0 // Length of Public Names Info LpubNames_start0: [...] LpubNames_end0: }Without -mattr=+ptx75 ptxas complains about labels and labelexpressions:error : Feature 'labels1 - labels2 expression in .section' requiresPTX ISA .version 7.5 or latererror : Feature 'Defining labels in .section' requires PTX ISA.version 7.0 or laterThe patch modifies dbg-value-const-byref.ll to let it run without PTX7.5 (available from CUDA 11.0), and adds a new test just for thiscase.Differential revision: https://reviews.llvm.org/D124108 List of files: /llvm-project-15.0.7/llvm/test/DebugInfo/NVPTX/debug-name-table.ll Tue, 19 Apr 2022 17:01:14 +0000 Andrew Savonichev <andrew.savonichev@gmail.com>
