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/thread/m68k/syscall_cp.s | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) create mode 100644 src/thread/m68k/syscall_cp.s (limited to 'src/thread/m68k/syscall_cp.s') diff --git a/src/thread/m68k/syscall_cp.s b/src/thread/m68k/syscall_cp.s new file mode 100644 index 00000000..5628a896 --- /dev/null +++ b/src/thread/m68k/syscall_cp.s @@ -0,0 +1,26 @@ +.text +.global __cp_begin +.hidden __cp_begin +.global __cp_end +.hidden __cp_end +.global __cp_cancel +.hidden __cp_cancel +.hidden __cancel +.global __syscall_cp_asm +.hidden __syscall_cp_asm +.type __syscall_cp_asm,@function +__syscall_cp_asm: + movem.l %d2-%d5,-(%sp) + movea.l 20(%sp),%a0 +__cp_begin: + move.l (%a0),%d0 + bne __cp_cancel + movem.l 24(%sp),%d0-%d5/%a0 + trap #0 +__cp_end: + movem.l (%sp)+,%d2-%d5 + rts +__cp_cancel: + movem.l (%sp)+,%d2-%d5 + move.l __cancel-.-8,%a1 + jmp (%pc,%a1) -- cgit v1.2.3
