From: Scott Wood Date: Fri, 16 Aug 2013 00:19:10 +0000 (-0500) Subject: powerpc/e500: Set -mcpu flag for 32-bit e500 X-Git-Tag: v3.12-rc1~123^2~28^2~6 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=847f56b0cc2fe431a1272eb586e316ba2c02c55f;p=linux.git powerpc/e500: Set -mcpu flag for 32-bit e500 Unlike 64-bit, we don't currently support multiplatform between e500 and non-e500, so the -mcpu is not configurable at this time. -msoft-float is specified when testing for -mcpu=8540 because otherwise some older toolchains will fail with "error: E500 and FPRs not supported".
