Subject: [ARM][Testsuite]make dump_stack function call conditional in cold-lc.c
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ef0e3441246ee1dc01b3bf39622bc53644b181f8;p=gcc.git

[ARM][Testsuite]make dump_stack function call conditional in cold-lc.c

After r249013, die () and dump_stack () are both in cold section. This makes
the compiler generate bl instruction for the function call, instead of
honoring the -mlong-calls option.

This patch changes the dump_stack function call conditional, which fixes the
regression.

	* gcc.target/arm/cold-lc.c: Update coding style, call dump_stack
	conditionally.
