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. --- arch/m68k/crt_arch.h | 14 ++++++++++++++ 1 file changed, 14 insertions(+) create mode 100644 arch/m68k/crt_arch.h (limited to 'arch/m68k/crt_arch.h') diff --git a/arch/m68k/crt_arch.h b/arch/m68k/crt_arch.h new file mode 100644 index 00000000..48a42f29 --- /dev/null +++ b/arch/m68k/crt_arch.h @@ -0,0 +1,14 @@ +__asm__( +".text\n" +".weak _DYNAMIC \n" +".hidden _DYNAMIC \n" +".global " START "\n" +START ":\n" +" suba.l %fp,%fp \n" +" movea.l %sp,%a0 \n" +" lea _DYNAMIC-.-8,%a1 \n" +" pea (%pc,%a1) \n" +" pea (%a0) \n" +" lea " START "_c-.-8,%a1 \n" +" jsr (%pc,%a1) \n" +); -- cgit 1.4.1
