From: Jan Beulich Date: Fri, 1 Jun 2018 06:39:08 +0000 (+0200) Subject: x86: simplify control register check X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4787f4a5860864337c4f1261713b9462b79ea16a;p=binutils-gdb.git x86: simplify control register check ... as is already done elsewhere: There's no need for the use of operand_type_equal() here - the bit identifying control registers isn't used for any other purposes. --- diff --git a/gas/ChangeLog b/gas/ChangeLog index 199a48d8303..fdf8b2b13ff 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,3 +1,8 @@ +2018-06-01 Jan Beulich + + * config/tc-i386.c (control): Delete. + (parse_real_register): Simply check "control" bit.
