Subject: xtensa: Remove redundant use of 'n'-constraint for call insns
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=915d2ecffecf7eaf9f14a46aca322326e2882a60;p=thirdparty%2Fgcc.git

xtensa: Remove redundant use of 'n'-constraint for call insns

Because 'i'-constraint clearly includes 'n'.

gcc/ChangeLog:

	* config/xtensa/xtensa.md (call_internal, call_value_internal,
	sibcall_internal, sibcall_value_internal): Remove 'n'-constraint.
