One achitectural problem here is that GCC doesn't emit bytes. It emits ASCII
text, in the form of assembly instructions, and it's
not always easy to predict how they'll look by the time they've been through
the assembler and then had relocs applied by the
linker. (Indeed, to know what particular bytes you'd end up with you'd need to
do everything the assembler and linker does, which
is why we have an assembler and linker - the stuff GCC emits isn't directly
executable...)
Shouldn't this be done in the linker instead?
