TODO

一如既往，主要在工具链领域耕耘。但由于工作忙碌在open source社区投入的时间减少了。

Blogging

不包括这篇总结，一共写了18篇文章。

• Understanding and improving Clang -ftime-report
• Natural loops
• lld 20 ELF changes
• Migrating comments to giscus
• Compiling C++ with the Clang API
• Relocation generation in assemblers
• LLVM integrated assembler: Improving MCExpr and MCValue
• LLVM integrated assembler: Improving expressions and relocations
• GCC 13.3.0 miscompiles LLVM
• LLVM integrated assembler: Engineering better fragments
• LLVM integrated assembler: Improving sections and symbols
• Understanding alignment - from source to object file
• Benchmarking compression programs
• lld 21 ELF changes
• Remarks on SFrame
• Stack walking: space and time trade-offs
• Sacramento游记
• Weak AVL Tree

llvm-project

• 翻新了integrated assembler，写了4篇相关的blog posts: https://maskray.me/blog/tags/assembler/

• Reviewed numerous patches. query is:pr created:>2025-01-01 reviewed-by:MaskRay => "989 Closed"

Linux kernel

贡献了两个commits，被引用了一次。

ccls

• clang.prependArgs
• 支持了LLVM 21和22

ELF specification

尝试推进compact section header table，没有取得共识。 一些成员希望采用general compression (like zstd)的方式，像SHF_COMPRESSED那样压缩section header table。包括我在内的另一些人不喜欢采用general compression。

Misc

Reported 6 feature requests or bugs to binutils.

• ld --build-id does not use symtab/strtab content
• gas: monolithic .sframe violates COMDAT group rule
• gas: Clarify whitespace between a label's symbol and its colon
• ld: Add --print-gc-sections=file
• ld riscv: Relocatable linking challenge with R_RISCV_ALIGN
• ld: add --why-live

旅行

• 第一次去：台南、西安、兰州、天水、Sacramento、Puerto Vallarta, Jalisco, Mexico、Mazatlán, Sinaloa, Mexico
• 曾经去过：台北(上一次是近11年前)、北京
