X-Git-Tag: basepoints/gcc-15~2947 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=846794ead2982fc85a3b1a83bbb831fa096b2b7c;p=thirdparty%2Fgcc.git Objective-C, Darwin: Fix a regression in handling bad receivers. This is seen on 32b hosts with a 64b multilib, and is an ICE when the build has checking enabled. The fix is to exit the routine early if the sender or receiver are already error_mark_node. gcc/objc/ChangeLog: * objc-next-runtime-abi-02.cc (build_v2_objc_method_fixup_call): Early exit for cases where the sender or receiver are known to be in error.
