Darwin does not support gsplit-dwarf.
2018-08-18 Iain Sandoe <iain@sandoe.co.uk>
gcc/
* config/darwin.c (darwin_override_options): If -gsplit-dwarf is set,
emit a diagnostic that it is not supported and reset the option.
* config/darwin.h (DRIVER_SELF_SPECS): Note that gsplit-dwarf is not
supported and consume the option. (ASM_FINAL_SPEC): New.
gcc/testsuite
* g++.dg/debug/dwarf2/pr85302.C: Skip unsupported split DWARF
test on Darwin.
* g++.dg/debug/dwarf2/pr85302.C: Likewise.
* gcc.dg/lto/pr83719_0.c: Likewise.
