[KeyInstr] Add DISubprogram::keyInstructions bit (#144107) 2025-06-30T07:01:55+00:00 Orlando Cazalet-Hyams orlando.hyams@sony.com 2025-06-30T07:01:55+00:00 140e1894f245896752d06a7f5c405a465b492e73 Patch 1/4 adding bitcode support. Store whether or not a function is using Key Instructions in its DISubprogram so that we don't need to rely on the -mllvm flag -dwarf-use-key-instructions to determine whether or not to interpret Key Instructions metadata to decide is_stmt placement at DWARF emission time. This makes bitcode support simple and enables well defined mixing of non-key-instructions and key-instructions functions in an LTO context. This patch adds the bit (using DISubprogram::SubclassData1). PR 144104 and 144103 use it during DWARF emission. PR 44102 adds bitcode support. See pull request for overview of alternative attempts. 
Patch 1/4 adding bitcode support.

Store whether or not a function is using Key Instructions in its DISubprogram so
that we don't need to rely on the -mllvm flag -dwarf-use-key-instructions to
determine whether or not to interpret Key Instructions metadata to decide
is_stmt placement at DWARF emission time. This makes bitcode support simple and
enables well defined mixing of non-key-instructions and key-instructions
functions in an LTO context.

This patch adds the bit (using DISubprogram::SubclassData1).

PR 144104 and 144103 use it during DWARF emission.
PR 44102 adds bitcode
support.

Add AtomGroup and AtomRank to DILocation behind compile time flag
EXPERIMENTAL_KEY_INSTRUCTIONS which is controlled by cmake flag
LLVM_EXPERIMENTAL_KEY_INSTRUCTIONS.

Add IR read-write roundtrip test in a directory that is unsupported unless the
CMake flag is enabled.
