Fixing Go’ s Linker: An Unexpected Journey into ARM64, DWARF, and Linker Internals

摘要

We encountered an unusual problem recently at Uber with Golang™ debugging, as our engineers began transitioning to Apple® Silicon hardware, which uses the ARM64 Instruction Set Architecture (ISA), rather than the x86/AMD64 ISA many of us have been using for many years now. This required some rather complex debugging of the toolchain itself by Uber engineers.
