Well, I don't feel to be expert, but it looks like effect of the
FUNCTION_BOUNDARY change from 8 to 16. According to comments in defaults.h
this is required by C++ ABI as it does use the last bit of pointer for
different purposes, so now GCC limits the alignment to 2, not 1.
Concerning the padding comparison, I guess -falign-loops=0 -falign-jumps=0
is needed to avoid it.
Other bug, that makes me more nervous is target/6104. It is shame that -march=pentium4
appears to be seriously broken for FP. I was trying to debug this failure and it appears
to be generic reload problem, but I didn't find the exact cause :(
