--- Comment #19 from Gary Funck <gary at intrepid dot com> 2012-08-12 18:30:25 UTC --- (In reply to comment #15) > Do we have a run-time testcase? I attached three compile-time test cases that check if the generated RTL refers to TImode values. The test cases are set up to only run on x86_64 and x86 targets. I confirmed that they work as expected on an x86_64 target (with and without the MAX_FIXED_MODE_SIZE patch). Not sure if it will work on x86 or not. The test case may have to be tweaked for x86. Is this sufficient? I don't know how a run-time test would demonstrate the use of TImode, except in the form of a benchmark.
