[RISC-V] .insn directive does not support constant arg #97498

Closed charlie-rivos closed 2 months ago

charlie-rivos commented 3 months ago

GNU-as supports a constant value to the .insn assembler directive as of commit: https://github.com/bminor/binutils-gdb/commit/a262b82fdbf4cda3b0648b1adc32245ca3f78b7a. The RISC-V LLVM assembler currently only supports the .insn directive with in the form of .insn <type>, <operand1>, <operand2>. Can the form of .insn <value> also be supported by Clang?

These are in a PR against the asm manual, but it hasn't landed yet: https://github.com/riscv-non-isa/riscv-asm-manual/pull/106

I will push that through first then, thank you!
