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

  17 # Syntax:   gccas OPTIONS... [asm file]
