Subject: rs6000: fix power10_hw test
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7126583af5d29235584b51b3b05eeaba2adef024;p=gcc.git

rs6000: fix power10_hw test

The code snippet for this test was returning 1 if power10
instructions executed correctly. It should return 0 if the
test passes.

	* lib/target-supports.exp (check_power10_hw_available):
	Return 0 for passing test.
