MIPS/GAS: Fix an ISA override not lifting ABI restrictionsbinutils-2_25-branch
Correct a regression introduced with commit 919731affbef ("Add MIPS
.module directive") causing code like:
.set mips3
dli $2, 0x9000000080000000
to fail assembly with the following error message produced:
Error: number (0x9000000080000000) larger than 32 bits
if built with `mips3' selected as the global ISA (e.g. `-march=mips3').
This is because a `.set' directive doing an ISA override does not lift
the ABI restriction on register sizes if the ISA remains unchanged.
Previously the directive always set register sizes from the ISA chosen,
which is what some code expects. Restore the old semantics then.
gas/
* config/tc-mips.c (code_option_type): New enum.
(parse_code_option): Return status indicating option type.
(s_mipsset): Update `parse_code_option' call site accordingly.
Always set register sizes from the ISA with ISA overrides.
(s_module): Update `parse_code_option' call site.
