News and articles from around the web
Nothing spotted this week.
On the mailing lists
Chris Bieneman reported back on the review managers' decision on adding a Bazel build configuration to the LLVM monorepo. A follow-up message provided more detail on the process that resulted in the decision to approve.
Kai Wang posted an RFC on permitting load/store/alloca for structs containing all scalable vectors.
Ondrej Sykora provided an update on proposals to implement the BHive methodology in llvm-exegesis, and is seeking feedback on the planned next steps.
Björn Pettersson summarised the current status of support for fixed point numbers in Clang/LLVM.
Haowei Wu initiated a discussion on merging llvm-elfabi with the llvm-ifs tool, linking to a draft merge plan.
John Byrd asked if any work had been done on using TableGen to help generate an emulator core.
LLVM GPU News Issue #8 is out.
Johannes Doerfert shared an RFC on adding an 'implements' attribute. This provides a way to replace a callee statically, inside the LLVM pipeline.
Stefan Gränitz proposes changing lli's default JIT engine to Orc rather than MCJIT.
Philipp Reames posted an RFC to change the referenceability attributes to imply point in time facts, and to re-infer stronger dereferenceability facts when needed. Respondents so far have supported the change, noting that the existing documented semantics aren't clear.
LLVM commits
Lit will now record test execution times and use that to determine the order tests are run in. 1d297f9.
Support for fixed-length vectors was added to the RISC-V calling convention. 0c5b789.
Support was added for
-fpatchable-fucntion-entryon RISC-V. 6ab8927.The OCaml bindings gained DebugInfo support. 506df1b.
Scalable-vector masked gather and scatter operations are now supported with the RISC-V vector extension. 0331399, 3495031.
The various LLVM sync-up calls are now documented. 64bb375.
Intrinsic overloading is now supported for unnamed types, fixing two bugs and laying more groundwork for full restrict. 04790d9.
VPlan gained plain text dumping, to further aid debugging. 93a9d2d.
The LangRef was expanded to describe the memory layout for vector types. 5737010.
Clang commits
-Bis no longer overloaded to perform GCC detection.--gcc-toolchainshould be used instead. 4c2da86, 94a793f.__rndrand__rndrrsintrinsics were added to AArch64 targets supporting Armv8.5-A random number instructions. ab86edb.Initial support was introduced for the OpenMP interop directive and use clause. 410f09a, c615927.
Other project commits
The MLIR memref dialect was created, and a number of operations from the std dialect were moved into it. e231070.
Helper functions used for the RISC-V
-msave-restoreoption were added to compiler-rt. b136a74.LLVM libc gained an implementation of
