本节内容来自 LLVM Weekly 第 577 期， Alex Bradbury 大哥持续稳定输出。

• 如期而至： LLVM 19.1.7 was released.

• 组织形式随着组织规模要发展： Renato Golin, on behalf of a range of MLIR contributors, shared a proposed new governance model for MLIR.

• LLVM LTS 的概念呼之欲出： Maxim Kuvyrkov kicked off an RFC thread on the possibility of an LLVM long-term support release.

• 更严谨： Tom Stellard suggested requiring contributors have at least 3 commits and acks from 2 current committers in order to be granted commit access.

• 这缩写容易混淆啊： Jacques Pienaar started a second RFC thread on incubating the MLIR tensor compute primitives (TCP) dialect.

• 更厉害： Franklin Zhang proposed upstreaming enhancements to BOLT for Linux kernel AArch64, reporting improvements of 8% on an nginx benchmark.

• 高通的贡献产出很快： Assembler/disassembler support was added to the RISC-V backend for the Qualcomm Xqciint (interrupts) extension. 171d3ed.

• 更猛算力： LLVM can now detect if the host is an Apple M4. a082cc1.

• 更安全： Stack clash protection for dynamic alloca was implemented for RISC-V. 01d7f43.

• 更友好： LLVM's libc documentation was reorganised to be more beginner friendly. 692c77f.
