[cfe-dev] Default stack alignment for x86 changed

Thank you all for the useful replies. It then looks like the default
alignment of 4 is good for win32 as well.
The conclusion I have is that the ABI does not 'require' alignment of 8
bytes for doubles, but in order to ensure that code runs with no performance
loss on all processor types, even older Pentiums, it would be 'recommended'
to align them on multiples of 8 byte.

Regards,
Alpar
