Revision 9a9657568bfd89a258db643352e38b5decfd059a authored by Eric Anholt on 20 October 2016, 23:48:12 UTC, committed by popcornmix on 08 January 2017, 11:42:05 UTC
The loop is scanning until the original max_ip (size of the BO), but we want to not examine any code after the PROG_END's delay slots. There was a block trying to do that, except that we had some early continue statements if the signal wasn't a PROG_END or a BRANCH. The failure mode would be that a valid shader is rejected because some undefined memory after the PROG_END slots is parsed as a branch and the rest of its setup is illegal. I haven't seen this in the wild, but valgrind was complaining when about this up in the userland simulator mode.
