From: Hirokazu Takata Date: Fri, 24 Feb 2006 21:03:50 +0000 (-0800) Subject: [PATCH] m32r: enable asm code optimization X-Git-Tag: v2.6.16-rc5~52 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cde05cf2145b0aa06dd61277060bfba5d38acb0b;p=linux-2.6 [PATCH] m32r: enable asm code optimization Add -O2 option to AFLAGS to enable asm code optimization for m32r. On m32r gas, "-m32r2 -O" option enables assembler's parallel code generation optimization for M32R2 ISA as a default. So, "-no-parallel" option is required explicitly for a cpu core with single instuction issuing, for example, VDEC2.
