— Move x86/ELF assembly back to Intel syntax
This used to be in Intel syntax, but was moved back to AT&T syntax for
consistency with the Mach-O version, where the assembler doesn't support
the Intel syntax properly. However, it makes more sense to use Intel
syntax where possible. (user: js, size: 3446) [annotate] [blame] [check-ins using]
