ctf: Do not warn for CTF not supported for GNU GIMPLE
CTF is supported for C only. 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.
