Subject: [testsuite] Add gcc.dg/ia64-sync-5.c
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6339f93279b24b5a61eeed2a5040b8b2a0d3ab42;p=gcc.git

[testsuite] Add gcc.dg/ia64-sync-5.c

There currently is no sync_char_short-enabled run test that tests
__sync_val_compare_and_swap.

Fix this by copying ia64-sync-3.c and modifying it for char/short.

Tested on x86_64.
