which looks ok to me.
It already isn't, why is the alignment 8 if __alignof__
(GENOME_LOC_TYPE_2) is 1?
The aligns are printed in bits. It really is okay, as is the MEM.
Uff, I'm always confused by align being printed after the unit size.
As some digging shows, already GCC 1.35 had effectively the same code.
As soon as parameters are passed in registers GCC loads the parts fitting
into registers as full words. We could simply sorry() for these cases, as
they never worked correctly. Though I suppose that's quite unforgiving,
as most of the time (struct in question not passing page border) it works
fine.
We should warn, I think.
