abi_apple_x64.c (1131B)

      1 /* Apple x86_64 (Darwin) ABI dispatch.
      2  *
      3  * Darwin x86_64 ABI is identical to Linux SysV x86_64; this seam exists
      4  * so future divergences (alignment, struct passing edge cases) have a
      5  * place to live.  Today the vtable thinly delegates to the SysV
      6  * classifier and reuses its va_list_info. */
