The libgcc support shared library on modern GCC versions (11 and later) is called
libgcc_s.1.1.dylib
on all Darwin platforms. While alibgcc_s.1.dylib
is still provided for backward compatibility on Intel Darwin, it is not recommended to use it.On aarch64-darwin,
libgcc_s.1.dylib
is not provided at all, which is why this was special-cased in the build system. But actually, linking againstlibgcc_s.1.1.dylib
in all cases on Darwin is the right way to go.
