...ose that all other tools, and especially LTO, would enable it. The savings are 20% of peak memory in LTO of clang itself. I could attach a patch, but first i’d really like to know if anyone is fundamentally opposed to this. I should note, a couple of issues have come up in the prototype. - llvm::getDISubprogram was walking the function body to find the subprogram. This is trivial to fix as functions now have !dbg on them. - The AsmPrinter is calling canBeOmittedFromSymbolTable on GlobalValue’s which then walks all their uses. I think this should be done earlier in codegen as an analysis whose results ar...
