[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
