From: Jan Kratochvil Date: Tue, 31 Jan 2017 01:01:09 +0000 (+0000) Subject: libcc1 base API: bump set_arguments; add set_driver_filename, set_triplet_regexp X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5d1b2443237a407785f84be09909f93abdcfec48;p=gcc.git libcc1 base API: bump set_arguments; add set_driver_filename, set_triplet_regexp for include/ChangeLog * gcc-interface.h (enum gcc_base_api_version): Update comment for GCC_FE_VERSION_1. (struct gcc_base_vtable): Rename set_arguments to set_arguments_v0. Add set_arguments, set_triplet_regexp and set_driver_filename. for libcc1/ChangeLog * libcc1.cc (libcc1): Add class compiler with field compilerp, class compiler_triplet_regexp and class compiler_driver_filename. (libcc1::libcc1): Initialize compilerp. (libcc1::~libcc1): Delete compilerp. (libcc1::compiler::find, libcc1::compiler_triplet_regexp::find) (libcc1::compiler_driver_filename::find): New methods. (libcc1_set_arguments): Remove parameter triplet_regexp. (libcc1_set_triplet_regexp, libcc1_set_driver_filename) (libcc1_set_arguments_v0): New functions. (vtable): Use libcc1_set_arguments_v0, add libcc1_set_arguments, libcc1_set_triplet_regexp and libcc1_set_driver_filename.
