[LLVMdev] ScheduleDAGInstrs/R600 test potential issue with implicit defs
Hi Tom,
Thanks a lot for your explanations, now it makes a lot more sense ;)
I had a slightly closer look at the R600 packetizer, and the issue is
that the third LSHL instruction has both an implicit use and
*afterwards* an implicit def of T1_XYZW. The latter def causes the
current ScheduleDAGInstrs implementation to ignore the implicit use,
thus the ScheduleDAG only contains an

[LLVMdev] Weird problems with cos (was Re: [PATCH v3 2/3] R600: Add carry and borrow instructions. Use them to implement UADDO/USUBO)
Hi Tom, Matt,
I'm running into strange issues with the cos test (piglit
generated_tests/cl/builtin/math/builtin-float-cos-1.0.generated.c)
I have been seeing random failures (incorrect results) for some time and
tried to investigate. the weird part is that the failures are not 100%
reproducible, sometimes the tests pass, or partly pass
(it's usually float8 and float16 subtests that
