Description of problem: We would like to update you with a bug fix we have identified on the latest Btgeneric 5334 (ia32exec.bin) we have delivered you on Sep 15th â targeted for EL3 U4 â Bug description: the translator maintains processor ordering compatibility of the source IA-32 application by either using affinity solution or using strong order version of the load/store IPF instructions ( acquire-release versions of the load / store instructions ). We have identified a bug in one of the optimizations that in certain case the generated code did not use the acquire- release versions of the instructions when it actually needed to. The bug was discovered during a code review â we have not seen failures in our test environment due to this bug â even on MP systems running stress testing - Bug fix: the fix was by eliminating the problematic optimization Although this bug did not duplicate on real tests, we still highly recommend the fix Version-Release number of selected component (if applicable): 5334
i tried to attach the binary with the fix, but its size exceeds the limit. we sent the binary thru email to bennet and sdenham on Sep 28. Please let me know if it was not recevied.
We did receive the new binary; thanks. We are requesting that Intel shoulder the testing effort with this new binary (as with previous ones!). In particular, we request that you perform benchmark tests as well as gcc, glibc, and mozilla-type tests. Elena Zannoni has already spoken to Geoff Gustafson, Intel engineer onsite at RH, about testing; Geoff can repeat some of the simpler testing that we we (with gdb and a simple ia32 program (break main; run) but can't go too far beyond that. We've posted the latest rpms (ia32el-1.1-3 in dist-4E-lacd and ia32el-1.1-2.EL3 in dist-3.0E-lacd-U4) at the following locations: partners.redhat.com/6fc892da0b7d82b0ae10ab220aecd7b8/RHEL4-ia32el and partners.redhat.com/6fc892da0b7d82b0ae10ab220aecd7b8/RHEL3-ia32el Please grab these rpms and test as rigorously as possible by next Wednesday, 6 October. We're quickly approaching RHEL 4 Beta 2 package freezee and need to ensure that testing is done ASAP. Many thanks.
Latest packages are now ia32el-1.1-6.EL3 (for RHEL3 U4 lacd) and ia32el-1.1-7 (for RHEL4 lacd).
Can we close this bug?
Yes, I'm closing it.
