8 of the 13 tests on Mac AArch64 labeled "OSX" fail prior to this PR. Here we fix the following: + Syscall success is indicated by the carry flag just like x86 Mac + Handle sigreturn with its extra parameters just like x86 Mac + Fix signal handler parameters + Fix stolen register support in signal contexts + Use MAP_JIT and pthread_jit_write_protect_np for +rwx gencode in tests + Use DYLD_LIBRARY_PATH on Mac in tests Now all 13 tests pass: --------------------------------------------------------------------------------------- ctest -j 5 -L OSX 1/13 Test #13: code_api|common.fib ................................

This is coming from the use of fxsaveq which is only supported by gas
2.16+. The inline asm ends up using your assembler rather than
CMAKE_ASM_COMPILER.
To fix, I would suggest replacing this line:
With this line:
And if your version of gas doesn't even support "rex64" (not sure when that
was added as a separate keyword) then this should always work:
Perhaps worth filing an Issue and fixing for real.
