Currently, a warning is emitted if the -gctf command line option is specified for a non-C frontend. This warning is also used by the GCC testsuite framework - it skips adding -gctf to the list of debug flags for automated testing, if CTF is not supported for the frontend. The following warning, however, is not useful in case of LTO: "lto1: note: CTF debug info requested, but not supported for ‘GNU GIMPLE’ frontend" This patch disables the generation of the above warning for GNU GIMPLE. gcc/ChangeLog: * toplev.c (process_options): Do not warn for GNU GIMPLE. --- diff --git a/gcc/toplev.c b/gcc/toplev.c index ecb2b694970c..1bb1794be964 100644 --- a/gcc/toplev.c +++ b/gcc/toplev.c @@ -1408,14 +1408,16 @@ process_options (bool no_backend) debug_info_level = DINFO_LEVEL_NONE; } - /* CTF is supported for only C at this time. - Compiling with -flto results in frontend language of GNU GIMPLE. */ + /* CTF is supported for only C at this time. */ if (!lang_GNU_C () && ctf_debug_info_level > CTFINFO_LEVEL_NONE) { - inform (UNKNOWN_LOCATION, - "CTF debug info requested, but not supported for %qs frontend", - language_string); + /* Compiling with -flto results in frontend language of GNU GIMPLE.
