Subject: Makefile.tpl: disable -Werror for feedback stage [PR111663]
X-Git-Tag: basepoints/gcc-15~5700

Makefile.tpl: disable -Werror for feedback stage [PR111663]

Without the change profiled bootstrap fails for various warnings on
master branch as:

    $ ../gcc/configure
    $ make profiledbootstrap
    ...
    gcc/genmodes.cc: In function ‘int main(int, char**)’:
    gcc/genmodes.cc:2152:1: error: ‘gcc/build/genmodes.gcda’ profile count data file not found [-Werror=missing-profile]
    ...
    gcc/gengtype-parse.cc: In function ‘void parse_error(const char*, ...)’:
    gcc/gengtype-parse.cc:142:21: error: ‘%s’ directive argument is null [-Werror=format-overflow=]

The change removes -Werror just like autofeedback does today.

/

	PR bootstrap/111663
	* Makefile.tpl (STAGEfeedback_CONFIGURE_FLAGS): Disable -Werror.
	* Makefile.in: Regenerate.
