--- Comment #9 from rvalue <i at rvalue dot moe> --- Hi Kito: Thank you for your follow-up patch! Confirmed that these patches do work. The test program compiles successfully with no `-misa-spec` flag or `-misa-spec=2.2` flag. But when I set `-misa-spec=20190608` or `-misa-spec=20191213`, it still fails. I think the file mentioned in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=104853#c7 is still buggy. Is there any future plan about this problem?
