Subject: [PATCH v3] RISC-V: Fixbug for f
The pattern mistakenly believes that fsflags can use immediate numbers,
but in fact it does not support it. Immediate numbers should use fsflagsi.
For example:
__builtin_riscv_fsflags(4);
The following error occurred.
/tmp/ccoWdWqT.s: Assembler messages:
/tmp/ccoWdWqT.s:14: Error: illegal operand
