Subject: Avoid dependence on libc headers in nvptx realloc.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=77d10a1b208d0e78ee638a49952276be9b830db4;p=gcc.git

Avoid dependence on libc headers in nvptx realloc.

	* config/nvptx/realloc.c: Include <stddef.h> instead of <stdlib.h>
	and <string.h>.
	(__nvptx_realloc): Call __builtin_memcpy instead of memcpy.
