Subject: [PATCH 1/3] Remove '-mno-explicit-relocs' option when CONFIG_BUILD_ELF64
Date: Tue, 13 Feb 2007 10:18:07 +0100	[thread overview]
Message-ID: <11713582891191-git-send-email-fbuihuu@gmail.com> (raw)
In-Reply-To: <1171358289786-git-send-email-fbuihuu@gmail.com>

From: Franck Bui-Huu <fbuihuu@gmail.com>

This patch removes '-mno-explicit-relocs' usage when
CONFIG_BUILD_ELF64 is set since this option was only required
with the old hack to truncate addresses at the assembly level
where "-mabi=64 -Wa,-mabi=32" was used.

This should yield a small code size improvement for inline
assembly, where the R constraint is used.

The idea is coming from Maciej <macro@linux-mips.org>.
