From 3b5c10724d7a0c29ae613bee7a0822131b06b5a8 Mon Sep 17 00:00:00 2001 From: Jan Kratochvil Date: Tue, 31 Jan 2017 01:00:51 +0000 Subject: [PATCH] libcc1 base API: add set_verbose and new version of compile for include/ChangeLog * gcc-interface.h (enum gcc_base_api_version): Add comment to GCC_FE_VERSION_1. (struct gcc_base_vtable): Rename compile to compile_v0. Update comment for compile. New methods set_verbose and compile. for libcc1/ChangeLog * libcc1.cc: Include intl.h. (struct libcc1): Add field verbose. (libcc1::libcc1): Initialize it. (libcc1_set_verbose): New function. (libcc1_set_arguments): Print messages for VERBOSE. (libcc1_compile): Remove parameter verbose. Use VERBOSE from SELF. (libcc1_compile_v0): New function. (vtable): Use libcc1_compile_v0 and add libcc1_compile and libcc1_set_verbose.
