; GCC "intrinsics" file entry point. ; ; This is invoked to build support files for registering intrinsic ; functions within gcc. this code has a fair bit of target-specific ; code in it. it's not a general-purpose module yet. ; ; Copyright (C) 2000, 2009 Red Hat, Inc. ; This file is part of CGEN. ; ; This is a standalone script, we don't load anything until we parse the ; -s argument (keeps reliance off of environment variables, etc.). ; Load the various support routines. ; Fix up Scheme to be what we use (guile is always in flux). "/guile.scm""/read.scm""/intrinsics.scm""-K""isa""keep isa <isa> in intrinsics""-M""file""generate insns.md in <file>""-N""file""generate intrinsics.h in <file>""-P""file""generate intrinsic-protos.h in <file>""-T""file""generate intrinsic-testsuite.c in <file>"; Kept global so it's available to the other .scm files. "."; Scan argv for -s srcdir. ; We can't process any other args until we find the cgen source dir. ; The result is srcdir. ; We assume "-s" isn't the argument to another option. Unwise, yes. ; Alternatives are to require it to be the first argument or at least preceed ; any option with a "-s" argument, or to put knowledge of the common argument ; set and common argument parsing code in every top level file. "`-s srcdir' not present, can't load cgen""-s""missing srcdir arg to `-s'"; Main routine, parses options and calls generators. ; Find and set srcdir, then load all Scheme code. ; Drop the first argument, it is the script name (i.e. argv[0]).
