New Revision: 302488
URL: http://llvm.org/viewvc/llvm-project?rev=302488&view=rev
Log:
Fix GCC 7 test failures.
This patch fixes the test failures and unexpected passes that occur
when testing against GCC 7. Specifically:
* don't mark __gcd as always inline because it's a recursive function. GCC diagnoses this.
* don't XFAIL the aligned allocation tests. GCC 7 supports them but not the -faligned-allocation option.
* Work around gcc.gnu.org/PR78489 in variants constructors.
