make md_parse_option () take a const char *
This is mostly just adding const in many places, however there are a couple interesting things. We need to add casts in tc-s390.c and tc-cris.c because they have functions that assign to input_line_pointer an argument that sometimes comes from md_parse_option. Presumably this is safe because those targets never pass literals to md_parse_option (), but this code should probably be improved in the future. Also xtensa passes the argument to strtoll which is a rather odd function, it takes a const char * as argument and returns a pointer into that string as a char * through an out argument, but we can work around that by adding more variables. gas/ChangeLog: 2016-03-29 Trevor Saunders <tbsaunde+binutils@tbsaunde.org> * config/tc-aarch64.c (struct aarch64_long_option_table): Ad const qualifier. * config/tc-alpha.c (md_parse_option): Likewise. * config/tc-arc.c (md_parse_option): Likewise. * config/tc-arm.c (struct arm_long_option_table): Likewise.
