# Synopsis: This shell script is a replacement for the old "gccas" tool that
|
|
# existed in LLVM versions before 2.0. The functionality of gccas has
|
|
# now been moved to opt and llvm-as. This shell script provides
|
|
# backwards compatibility so build environments invoking gccas can
|
|
# still get the net effect of llvm-as/opt by running gccas.
|
|
#
|
|
# Syntax: gccas OPTIONS... [asm file]
