Andi Kleen <andi-gcc at firstfloor dot org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |andi-gcc at firstfloor dot org --- Comment #4 from Andi Kleen <andi-gcc at firstfloor dot org> --- Perhaps using -Og (or -O1) if available? I actually like to use unoptimized stage1 gcc to debug things with gdb, The last time I checked the worst offenders were some of the C++ inlines not getting inlined, and especially the new RTL code very heavily relies on that. Perhaps just #define inline __attribute__((always_inline)) inline for stage1 would be good enough to fix the worst.
