Hi Mikael and Harald,
- inline expansion is inhibited at -Os. But wouldn't it be good if we make this expansion also dependent on -ffrontend-optimize? (This was the case for rank-1 before your patch).
The original idea was to have -ffrontend-optimize as a check if anything went wrong with front-end optimization in particular - if the bug went away with -fno-frontend-optimize, we knew where to look (and I knew I had to look). So, probably better to not do this at -Os. One thought: Should we also do the inlining without optimization? Very nice set of patches! Best regards Thomas
