X-Git-Tag: binutils-2_29~578
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=27bfc1d1c2cbcafccddef51ef82b309ef147c4a8;p=external%2Fbinutils.git

Remove some uses of MAX_REGISTER_SIZE from mips-linux-tdep.c

gdb/
	* mips-linux-tdep.c (mips_supply_gregset): Use raw_supply_zeroed.
	(mips_supply_fpregset): Likewise.
	(mips64_supply_gregset): Likewise.
