Subject: x86: Remove 32-bit sign extension in offset_in_range
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7a705315596cf5effe01de8c3ac2535687c5663d;p=binutils-gdb.git

x86: Remove 32-bit sign extension in offset_in_range

When encoding a 32-bit offset, there is no need to sign-extend it to 64
bits since only the lower 32 bits are used.

	* config/tc-i386.c (offset_in_range): Remove 32-bit sign
	extension.
