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/setjmp/m68k/longjmp.s | 14 ++++++++++++++ src/setjmp/m68k/setjmp.s | 18 ++++++++++++++++++ 2 files changed, 32 insertions(+) create mode 100644 src/setjmp/m68k/longjmp.s create mode 100644 src/setjmp/m68k/setjmp.s (limited to 'src/setjmp') diff --git a/src/setjmp/m68k/longjmp.s b/src/setjmp/m68k/longjmp.s new file mode 100644 index 00000000..cdb05fb5 --- /dev/null +++ b/src/setjmp/m68k/longjmp.s @@ -0,0 +1,14 @@ +.global _longjmp +.global longjmp +.type _longjmp,@function +.type longjmp,@function +_longjmp: +longjmp: + movea.l 4(%sp),%a0 + move.l 8(%sp),%d0 + bne 1f + move.l #1,%d0 +1: movem.l (%a0),%d2-%d7/%a2-%a7 + fmovem.x 52(%a0),%fp2-%fp7 + move.l 48(%a0),(%sp) + rts diff --git a/src/setjmp/m68k/setjmp.s b/src/setjmp/m68k/setjmp.s new file mode 100644 index 00000000..15e549b0 --- /dev/null +++ b/src/setjmp/m68k/setjmp.s @@ -0,0 +1,18 @@ +.global ___setjmp +.hidden ___setjmp +.global __setjmp +.global _setjmp +.global setjmp +.type __setjmp,@function +.type _setjmp,@function +.type setjmp,@function +___setjmp: +__setjmp: +_setjmp: +setjmp: + movea.l 4(%sp),%a0 + movem.l %d2-%d7/%a2-%a7,(%a0) + move.l (%sp),48(%a0) + fmovem.x %fp2-%fp7,52(%a0) + clr.l %d0 + rts -- cgit v1.2.1
