Sorry but I'm not very familiar with how we deal with CI failures. Should I revert the patch and reland it after fixing? Or I just push another patch to fix it? |
|
Yes the correct way is to revert the commit briefly mentioning the failure in the commit message (maybe just put a link to the build bot). And then reland later. |

#112143)" This reverts commit d8fadad. The commit breaks the following CI builds: - ppc64le-mlir-rhel-clang: https://lab.llvm.org/buildbot/#/builders/129/builds/7685 - ppc64le-flang-rhel-clang: https://lab.llvm.org/buildbot/#/builders/157/builds/10338
|
Reverted, will reland later after fixing the build error. |
|
I guess you have to replace std::reduce since this is apparently not supported on power pc. std::accumulate seems to have uses in llvm so I supposes this maybe the way to go. When you reland the PR it makes sense to add the commit hash of the original commit and of the revert commit to the commit message for transparency. |

This patch adds operand bundle support for `llvm.intr.assume`. This patch actually contains two parts: - `llvm.intr.assume` now accepts operand bundle related attributes and operands. `llvm.intr.assume` does not take constraint on the operand bundles, but obviously only a few set of operand bundles are meaningful. I plan to add some of those (e.g. `aligned` and `separate_storage` are what interest me but other people may be interested in other operand bundles as well) in future patches. - The definitions of `llvm.call`, `llvm.invoke`, and `llvm.call_intrinsic` actually define `op_bundle_tags` as an operation property. It turns out this approach would introduce some unnecessary burden if applied equally to the intrinsic operations because properties are not available through `Operation *` but we have to operate on `Operation *` during the import/export of intrinsics, so this PR changes it from a property to an array attribute. This patch relands commit d8fadad.
