That is what you think is important. To AVR users, compile time could
increase by 100% and they wouldn't care, but they do care when there is a
compiled code size regression of even 1%.
I was talking about code size, not compile time.
If you look at CSiBE, you can see how gcc improved for -Os over time:
2004-01-11 2007-04-01 diff
arm-elf 3850000 3570000 -7.3%
mips-elf 4010000 3830000 -4.5%
ppc-elf 3670000 3490000 -5%
sh-elf 3300000 3170000 -4%
2004-08-08 2006-12-17 diff
arm-linux 3420000 3370000 -1.5%
2004-12-05 2006-06-17 diff
bfin-elf 3140000 3120000 -1%
Maybe you can look at the development of code size of AVR over time,
and show a different trend, but I'd be surprised.
