Subject: contrib/regression/btest-gcc.sh: Handle multiple options.
X-Git-Tag: basepoints/gcc-15~4336
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0ca1e90ae1a3b0ecb4ae90f9b785e618b295a3ff;p=thirdparty%2Fgcc.git

contrib/regression/btest-gcc.sh: Handle multiple options.

This is a long-standing bug: passing "-j --add-passes-despite-regression"
or "--add-passes-despite-regression -j" caused the second option to be
treated as TARGET; the first non-option parameter.

	* btest-gcc.sh (Option handling): Handle multiple options.
