This is a NFC patch. This patch run a bulk update on CodeGen tests that are impacted by the true16 features. This patch applies: 1. duplicate GFX11plus runlines and apply them with "+mattr=+real-true16" and "+mattr=-real-true16" 2. update the test with the update script For some GISEL runlines, the current CodeGen do not fully support the true16 version. Still update the runlines, but comment out the failing one, and added a "FIXME-TRUE16" comment to that test for easier tracking. These test will be fixed in the following patches. This is in a transition state that we support both "+real-true16/-real-true16" in our code base. We plan to move to "+real-true16" as default, and finally remove "-real-true16" mode and test lines.
We should leave these for EXPENSIVE_CHECKS builds. Some of these were near the top of slowest tests.
This reverts commit ca33649abe5fad93c57afef54e43ed9b3249cd86.
This reverts commit e215a1e27d84adad2635a52393621eb4fa439dc9 as it broke both hip and openmp buildbots.
MSG_DEALLOC_VGPRS slows down very small waveslot limited kernels. It's been identified this message is only really needed for VGPR limited kernels. A kernel becomes VGPR limited if a total number of VGPRs per SIMD / number of used VGPRs is more than a number of wave slots.
Any SGPR read by a VALU can potentially obscure SALU writes to the same register. Insert s_wait_alu instructions to mitigate the hazard on affected paths. Compute a global cache of SGPRs with any VALU reads and use this to avoid inserting mitigation for SGPRs never accessed by VALUs. To avoid excessive search when compile time is priority implement secondary mode where all SALU writes are mitigated. Co-authored-by: Shilei Tian <shilei.tian@amd.com>
This reverts commit adaff46d087799072438dd744b038e6fd50a2d78. Drop the -O3 checks from default-attributes.hip. I don't know why they are different on some bots but reverting this is far too disruptive.
This reverts commits 677cc15e0ff2e0e6aa30538eb187990a6a8f53c0 and 78bc1b64a6dc3fb6191355a5e1b502be8b3668e7. The test CodeGenHIP/default-attributes.hip is failing on multiple bots even after the attempted fix including the following: - https://lab.llvm.org/buildbot/#/builders/3/builds/1473 - https://lab.llvm.org/buildbot/#/builders/65/builds/1380 - https://lab.llvm.org/buildbot/#/builders/161/builds/595 - https://lab.llvm.org/buildbot/#/builders/154/builds/1372 - https://lab.llvm.org/buildbot/#/builders/133/builds/1547 - https://lab.llvm.org/buildbot/#/builders/81/builds/755 - https://lab.llvm.org/buildbot/#/builders/40/builds/570 - https://lab.llvm.org/buildbot/#/builders/13/builds/748 - https://lab.llvm.org/buildbot/#/builders/12/builds/1845 - https://lab.llvm.org/buildbot/#/builders/11/builds/1695 - https://lab.llvm.org/buildbot/#/builders/190/builds/1829 - https://lab.llvm.org/buildbot/#/builders/193/builds/962 - https://lab.llvm.org/buildbot/#/builders/23/builds/991 - https://lab.llvm.org/buildbot/#/builders/144/builds/2256 - https://lab.llvm.org/buildbot/#/builders/46/builds/1614 These bots have been broken for a day, so reverting to get everything back to green.
Removing it from the codegen pipeline induces a lot of test churn because llc is no longer optimizing out implicit arguments to kernels. Mostly mechanical, but there are some creative test updates. I preferred to take the changes as-is in tests where the ABI isn't relevant. In cases where it's more relevant, or the optimize out logic was too ingrained in the test, I pre-run the optimization. Some cases manually add attributes to disable inputs.
