Subject: glapi: gl_SPARC_asm.py use argparse instead of getopt
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=86c9fb526ed9b0a68eb7bb29d661b7f61415d3f0;p=mesa.git

glapi: gl_SPARC_asm.py use argparse instead of getopt

Also drop -m switch, which only accepted a single value or raised an
error, and was unused in the makefile.
