It is no longer necessary to get good performance, there is only a small speed difference between -O2 and -O3, so just stick to the default of -O2. This also fixes the stack space usage on parisc. The compiler was buggy for -O3 and used ~3KB of stack space for several functions. With -O2 the problem is completely resolved, and stack space is back to a few hundred bytes. Additionally, we get a large code size win on gcc: | Compiler | Before (Bytes) | After (Bytes) | Delta (Bytes) | |----------|----------------|---------------|---------------| | gcc-11 | 952754 | 738954 | -213800 | | clang-12 | 976290 | 938826 | -37464 | |
