https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114036 --- Comment #8 from GCC Commits --- The releases/gcc-11 branch has been updated by Iain D Sandoe : https://gcc.gnu.org/g:5feeb2ddc93de85dffd7d52119189cd63bccd40f commit r11-11405-g5feeb2ddc93de85dffd7d52119189cd63bccd40f Author: Iain Sandoe Date: Sun Mar 31 11:27:53 2024 +0100 testsuite, Darwin: Allow for an undefined symbol [PR114036]. Darwin's linker defaults to requiring all symbols to be defined at static link time (unless specifically noted or dynamic lookuo is enabled). For this test, we just need to note that the symbol is expected to be undefined. PR testsuite/114036 gcc/testsuite/ChangeLog: * gcc.misc-tests/gcov-14.c: Allow for 'Foo' to be undefined on Darwin link lines.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114036 --- Comment #3 from Francois-Xavier Coudert --- There's only one symbol we care about here, and its name is known, so I'll make a patch with your suggestion and test it.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114036 --- Comment #2 from Iain Sandoe --- if there are lots of symbols that need to be undefined .. then one can use an undefined symbols file. Of course, it does not work if we do not know the symbol names at build-time.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114036 --- Comment #1 from Iain Sandoe --- yeah, there is a better way to do this with ld64 (and presumably dyld-ld), my guess is that this is an anachronism from the ld_classic (v1) days. We can tell the linker it's OK for a symbol to be undefined - and then that makes it behave like the ELF case. "-Wl,-U,_symbol_name " is the incantation to do this - and AFAIK should work back to i686-darwin9 (which is the earliest I test these days).
