From f81e44a0d96c88e052e51982f9fdd6fe0a212b46 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Thu, 14 Jun 2018 14:26:30 -0400 Subject: add m68k port three ABIs are supported: the default with 68881 80-bit fpu format and results returned in floating point registers, softfloat-only with the same format, and coldfire fpu with IEEE single/double only. only the first is tested at all, and only under qemu which has fpu emulation bugs. basic functionality smoke tests have been performed for the most common arch-specific breakage via libc-test and qemu user-level emulation. some sysvipc failures remain, but are shared with other big endian archs and will be fixed separately. --- src/internal/m68k/syscall.s | 9 +++++++++ 1 file changed, 9 insertions(+) create mode 100644 src/internal/m68k/syscall.s (limited to 'src/internal/m68k') diff --git a/src/internal/m68k/syscall.s b/src/internal/m68k/syscall.s new file mode 100644 index 00000000..9972a34d --- /dev/null +++ b/src/internal/m68k/syscall.s @@ -0,0 +1,9 @@ +.global __syscall +.hidden __syscall +.type __syscall,%function +__syscall: + movem.l %d2-%d5,-(%sp) + movem.l 20(%sp),%d0-%d5/%a0 + trap #0 + movem.l (%sp)+,%d2-%d5 + rts -- cgit v1.2.1
