SymtabSection::emitStabs() writes the symbol table in the order of externalSymbols, which has the order of symtab->getSymbols(), which is just the order symbols are added to the symbol table. In practice, symbols in the symbol files of input .o files are sorted, but since that's not guaranteed we sort them in ObjFile::parseSymbols(). To make sure several symbols with the same address keep the order they're in the input file, we have to use stable_sort(). In practice, std::sort() on already-sorted inputs won't change the order of just adjacent elements, and while in theory std::sort() could use a random pivot, in practice the code should be deterministic as it was previously too. But now lld/test/MachO/stabs.s passes with LLVM_ENABLE_EXPENSIVE_CHECKS=ON (the last test that was failing with that set). Fixes a regression from D99972. While here, remove an empty section in stabs.s and move .subsections_via_symbols to the end where it usually is (this part no behavior change).

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.
