I previously fixed a bug with the patterns that generate TST. I added these testcases to make our regression testing more solid. They've been running on our internal branch for about a month. OK to commit to trunk? Cheers, Ian 2013-05-02 Ian Bolton <ian.bolton@arm.com> * gcc.target/aarch64/tst_1.c: New test. * gcc.target/aarch64/tst_2.c: Likewise
