The idea is that the CC1 default for ELF should set dso_local on default visibility external linkage definitions in the default -mrelocation-model pic mode (-fpic/-fPIC) to match COFF/Mach-O and make output IR similar. The refactoring is made available by 2820a2ca3a0e69c3f301845420e0067ffff2251b. Currently only x86 supports local aliases. We move the decision to the driver. There are three CC1 states: * -fsemantic-interposition: make some linkages interposable and make default visibility external linkage definitions dso_preemptable. * (default): selected if the target supports .Lfoo$local: make default visibility external linkage definitions dso_local * -fhalf-no-semantic-interposition: if neither option is set or the target does not support .Lfoo$local: like -fno-semantic-interposition but local aliases are not used. So references can be interposed if not optimized out. Add -fhalf-no-semantic-interposition to a few tests using the half-based semantic interposition behavior. |
