CC llvm-dev ---------- Forwarded message ---------- Hello Duncan The size of ARM binaries created by clang has increased after r236642. Would you be able to find some time to look at my findings and share your thoughts about the problem, please? r236642 prevents emitting of temp label names into object files to save memory. This is fine, the label names do not appear in the resulting binaries. However, this creates some problems...

...d of MCSymbolData). As a result, during object emission we save ~6 pointers per MCSymbol, eliminate lookup indirection between MCSymbol and MCSymbolData, and avoid allocation overhead for MCSymbolData. I've measured ~4% memory savings on `llc` with this patch (using the same -flto -g input as r236642 and r236629 before it), dropping memory usage from 1058 MB down to 1017 MB. Before I clean this up and commit it (obviously in more incremental patches (and I'll do the same cleanup for MCSection)), I wanted to confirm the direction. -------------- next part -------------- A non-text attachme...
