The majority of code has not been ported to non-x86. To obtain a
healthy
base of compilable code, non-x86 platforms should be compatible
with x86
as much as possible, not the other way around.
It should be compatible where reasonable, but it doesn't make sense
to emulate all x86 peculiarities on non-x86. Otherwise e.g. "longint
shl 32" also has to be emulated as "shl 0" on ppc (rather than
setting the result to 0), all intermediate floating point
calculations have to be performed using soft float 80 bit math and
only the end result rounded back to 64/32 bit, etc.
I disagree that having "extended" bit compatible with the i386 is
required to be able to port most code. Extended, like comp, is an x86-
specific type and you only get approximate behaviour when using it on
other architectures (in case of comp the difference is at compile
time, due to comp being an integer rather than a floating point type
on non-i386).
