LLVM/Clang/LLDB/LLD

本节内容来自 LLVM Weekly 第390期， Alex Bradbury 大哥持续稳定输出。

• A new book on LLVM has been published - Learn LLVM 12 by Kai Nacke. 大家支持正版。

• The thread suggesting a migration to Discourse has seen continued discussions. 主要是社区觉得 mailman 维护起来太困难了。但是又有一批人拒绝使用浏览器。所以各种讨论。

• LLVM GPU News Issue #14 is out.

• Kito Cheng posted an RFC on providing a #pragma to implement the riscv_vector.h contents, avoiding the parsing of ~60k lines. David Rector pointed to recent work to solve a similar problem in OpenCL.

• Initial GlobalISel infrastructure was added for M68k. 2193347.

• Relocation emission for RISC-V was refactored and improved, bringing it more closely in line with GNU as. bbea642.
