From aab1b16a61d653173b1c5f158c51ec08dd6605b0 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Thu, 12 Jul 2007 09:48:54 +0900 Subject: [PATCH] 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.
