Subject: Darwin: Recognise -weak_framework in the driver [PR116237].
X-Git-Tag: basepoints/gcc-16~6750
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4cec7bc79db52bae159c3c60a415e2aea48051d8;p=thirdparty%2Fgcc.git

Darwin: Recognise -weak_framework in the driver [PR116237].

XCode compilers recognise the weak_framework linker option in the driver
and forward it.  This patch makes GCC adopt the same behaviour.

	PR target/116237

gcc/ChangeLog:

	* config/darwin.h (SUBTARGET_DRIVER_SELF_SPECS): Add a spec for
	weak_framework.
	* config/darwin.opt: Handle weak_framework driver option.
