Subject: Use CONST_VECTOR_ELT instead of XVECEXP
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8eff75e0d2a3495c5bc182324644a080d47205ac;p=gcc.git

Use CONST_VECTOR_ELT instead of XVECEXP

This patch replaces target-independent uses of XVECEXP with uses
of CONST_VECTOR_ELT.  This kind of replacement isn't necessary
for code specific to targets other than AArch64.

	* simplify-rtx.c (simplify_const_binary_operation): Use
	CONST_VECTOR_ELT instead of XVECEXP.
