All,

Attached is a small patch that primarily fixes the check for
the cmov instruction to support the GAS/USL syntax. Becuase
this file was also touched by my on-going SCO port, there is
a thunk in here that enabled hidden support for the native
LD, which supports it just fine.

["cmov.patch" (text/plain)]

2005-11-30  Kean Johnston  <jkj@sco.com>

	* config.in: HAVE_AS_IX86_CMOV_ATT_SYNTAX: Added.
	* configure.ac: SCO platforms support hidden attribute with their
	native linker.
	Check for USL/ATT cmov syntax as well as Sun syntax. Defines
	HAVE_AS_IX86_CMOV_ATT_SYNTAX if thats what the assembler supports.
