From f81e44a0d96c88e052e51982f9fdd6fe0a212b46 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Thu, 14 Jun 2018 14:26:30 -0400 Subject: [PATCH] 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/atomic_arch.h | 8 + arch/m68k/bits/alltypes.h.in | 31 +++ arch/m68k/bits/endian.h | 1 +
