From c8fdd247255a3a027cd9f66dcf93e6847d1d2f85 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Wed, 2 May 2007 19:27:06 +0200 Subject: [PATCH] x86: Drop cc-options call for all options supported in gcc 3.2+ The kernel only supports gcc 3.2+ now so it doesn't make sense anymore to explicitely check for options this compiler version already has. This actually fixes a bug. The -mprefered-stack-boundary check never worked because gcc rightly complains CC arch/i386/kernel/asm-offsets.s cc1: -mpreferred-stack-boundary=2 is not between 4 and 12 We just never saw the error because of cc-options. I changed it to 4 to actually work. Tested by compiling i386 and x86-64 defconfig with gcc 3.2. Should speed up the build time a tiny bit and improve stack usage on i386 slightly.
