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. --- configure | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'configure') diff --git a/configure b/configure index 09a0c436..f940af9a 100755 --- a/configure +++ b/configure @@ -320,6 +320,7 @@ i?86*) ARCH=i386 ;; x86_64-x32*|x32*|x86_64*x32) ARCH=x32 ;; x86_64-nt64*) ARCH=nt64 ;; x86_64*) ARCH=x86_64 ;; +m68k*) ARCH=m68k ;; mips64*|mipsisa64*) ARCH=mips64 ;; mips*) ARCH=mips ;; microblaze*) ARCH=microblaze ;; @@ -641,6 +642,13 @@ if test "$ARCH" = "aarch64" ; then trycppif __AARCH64EB__ "$t" && SUBARCH=${SUBARCH}_be fi +if test "$ARCH" = "m68k" ; then +if trycppif "__HAVE_68881__" ; then : ; +elif trycppif "__mcffpu__" ; then SUBARCH="-fp64" +else SUBARCH="-sf" +fi +fi + if test "$ARCH" = "mips" ; then trycppif "__mips_isa_rev >= 6" "$t" && SUBARCH=${SUBARCH}r6 trycppif "_MIPSEL || __MIPSEL || __MIPSEL__" "$t" && SUBARCH=${SUBARCH}el -- cgit v1.2.1
