SubjectBig kernel size increase with gcc 3.4
Hello,

these figures speak for themselves:

text data bss dec hex filename
833352 47200 78884 959436 ea3cc linux-2.6.x/vmlinux_gcc331
877420 53212 78884 1009516 f676c linux-2.6.x/vmlinux_gcc34


- target is linux-2.6.0-test2-uc0 for m68knommu (full config
available on request);

- same optimization flags: -m5307 -O2 -fno-strict-aliasing
-fno-common -fno-builtin -fomit-frame-pointer

- same ColdFire GCC patches were used (I strongly doubt it
could be a back-end issue);

- gcc-3.3.1-20030720 VS gcc-3.4-20030806.

I can provide more datails if needed. Could be an inlining issue
of course.

Out of curiosity, it seems that the old 2.95.3 could finally be
sent to rest now:

text data bss dec hex filename
833352 47200 78884 959436 ea3cc linux-2.6.x/vmlinux_gcc331
857208 72800 60836 990844 f1e7c linux-2.6.x/vmlinux_gcc295
