Programming / Re: Test build of GCC 4.7.3 available
« on: September 02, 2013, 06:56:28 pm »
Tested by running the FFMpeg FATE test-suite. With 4.4.6 and a P4 all tests pass. With a core2duo (now dead) and 4.4.6 there were perhaps a dozen failures, probably related to SSE3 alignment issues (possibly nasm bugs?). With 4.7.3 there were quite a few errors including hangs forcing me to kill the script.
To test, clone master, configure with something like configure --enable-gpl --disable-debug --disable-doc --samples=/fate.ffmpeg/fate-suite --enable-os2threads --cpu=i686
make && make fate-rsync && make fate.
Need the --cpu=i686 to pull in the GCC atomics. I'd guess the problems are alignment related but could be related to the GCC atomic operations.
