Subject: ivopts: Fix scan-assembler-not regexes for aarch64/sve test
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=7a1aea7e6a80c742e7e434c9a8e3501d109e0fbf;p=thirdparty%2Fgcc.git

ivopts: Fix scan-assembler-not regexes for aarch64/sve test

The test added by r16-1671-ge7ff8e8d77df74 passed despite using
regular expressions that would never match real assembly language
output from the compiler. Because the regular expressions were not
expected to match, and didn't, this was not noticeable; however,
it also made that part of the test useless.

The regular expressions have been fixed. Verified that the fixed
regular expressions do match assembly language output produced by
the compiler before the changes to ivopts in commit e7ff8e8d77d,
but do not match assembly language output produced by the compiler
after the changes to ivopts.

gcc/testsuite/ChangeLog:

	* gcc.target/aarch64/sve/adr_7.c: Fix regular expressions.
