Comment(by erikd):
The
[http://developer.apple.com/library/mac/#documentation/DeveloperTools/Conceptual/MachORuntime/Reference/reference.html
Mach-O documentation] suggests that the alignment is calculated by:
{{{
misalignment = (header.sizeofcmds + sizeof(header)) & 0xF;
return misalignment ? (16 - misalignment) : 0;
}}}
is all about finding the start of the actual code within the object file.
My reading of the ELF documentation suggests that the ELF version should
look like this:
{{{
misalignment = header.e_ehsize & 0xF;
return misalignment ? (16 - misalignment) : 0;}}}
}}}
but that still doesn't work. For all the ghc generated object files I've
seen the .text section immediately follows the `ELF` header whose size if
specified by e_ehsize.
