--- Comment #5 from Iain Sandoe <iains at gcc dot gnu.org> --- Created attachment 55523 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=55523&action=edit Patch for testing I tested this (by bootstrapping GCC with it) on x86_64 darwin21 with Xcode 14.3. FWIW; The reason I had not done this sooner, is that I do not have a sensible way to look up the SDK version at the moment (the second parameter), but AFAIK 0.0 is allowed as a "don't know", so we can improve on this at a later time Here, I will test on some earlier Darwin versions - but would welcome confirmation that it fixes the XC15 issue. ----- ``` COLLECT_GCC_OPTIONS='-B' 'gcc' '-o' 'hc' '-v' '-save-temps' '-mmacosx-version-min=12.0.0' '-nodefaultexport' '-mtune=core2' '-dumpdir' 'hc.' gcc/collect2 -syslibroot /Library/Developer/CommandLineTools/SDKs/MacOSX12.3.sdk/ -dynamic -arch x86_64 -platform_version macos 12.0.0 0.0 -o hc -Lgcc hc-hello.o -v -lemutls_w -lgcc -lSystem -no_compact_unwind collect2 version 14.0.0 20230707 (experimental) [remotes/home/master revision r14-2384-gbb3b9c1c3ba8] gcc/collect-ld -syslibroot /Library/Developer/CommandLineTools/SDKs/MacOSX12.3.sdk/ -dynamic -arch x86_64 -platform_version macos 12.0.0 0.0 -o hc -Lgcc hc-hello.o -v -lemutls_w -lgcc -lSystem -no_compact_unwind @(#)PROGRAM:ld PROJECT:ld64-857.1 ```
