From: Paul Mundt Date: Thu, 12 Jul 2007 00:48:54 +0000 (+0900) Subject: sh: Don't let SH-4A clobber SH-4 CFLAGS. X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=aab1b16a61d653173b1c5f158c51ec08dd6605b0;p=linux-beck.git sh: Don't let SH-4A clobber SH-4 CFLAGS. Older compilers don't support the -m4a{,nofpu} flags, which has the side-effect of allowing FP operations to be emitted. Switch this to incremental tuning, so we at least have -m4-nofpu as a fallback for the gcc3 toolchains. Without this, certain modules emit references to __udivsi3_i4 and __sdivsi3_i4.
