Subject: [MIPS] Remove '-mno-explicit-relocs' option when CONFIG_BUILD_ELF64
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=8c67316e706cabc2145d6c8e97f0bd8f2a86d8a1;p=deliverable%2Flinux.git

[MIPS] Remove '-mno-explicit-relocs' option when CONFIG_BUILD_ELF64

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>.
