Re: Severe problems with vectorizing stuff in 4.0.3 HEAD
Yes, in fact that's *exactly* what GCC is assuming.
And it will be true for all code that GCC generates.
How can that possibly ever work? Is the assumption then
that the only code GCC will ever work with is code that
GCC compiled? In effect what this implies is that GCC
is re-defining the ABI. It also means it is impossible
for GCC to inter-operate with vendor supplied libraries
like libc. If I use a libc function that has a callback,
like ftw() or bsearch() or qsort(), then I cannot have
them call a function that was compiled with gcc, becasue
no ABI previously defined has made it a requirement for
every stack frame to be 16-byte aligned.
