to decrease sizeof(SymbolUnion) by 8 on ELF64 platforms. Symbols needing such information are typically 1% or fewer (5134 out of 560520 when linking clang, 19898 out of 5550705 when linking chrome). Storing them elsewhere can decrease memory usage and symbol initialization time. There is a ~0.8% saving on max RSS when linking a large program. Future direction: * Move some of dynsymIndex/verdefIndex/versionId to SymbolAux * Support mixed TLSDESC and TLS GD without increasing sizeof(SymbolUnion) Reviewed By: peter.smith Differential Revision: https://reviews.llvm.org/D116281 |

LLVM Linker (lld)
This directory and its subdirectories contain source code for the LLVM Linker, a modular cross platform linker which is built as part of the LLVM compiler infrastructure project.

Benchmarking
In order to make sure various developers can evaluate patches over the same tests, we create a collection of self contained programs.
