.SH NAME
powerpc_as \- assembler for PowerPC

.SH SYNOPSIS
as [options] argument ...

.SH DESCRIPTION
This assembler is made with the general framework
described in \fIuni_ass\fP(6).

.SH SYNTAX
Most 32-bit integer and floating point instructions are supported, but not many
short form instructions. Instructions which take 16-bit operands can additionally
use the following special functions:

.IP hi16[value], ha16[value]
Returns the high half of the value of the expression; if the value is not absolute,
also generates the appropriate fixup. Use of either of these \fImust\fR be followed,
in the next instruction, by the corresponding use of \fBlo16[]\fR. Use \fBhi16[]\fR
if the low half is going to interpret its payload as an unsigned value, and
\fBha16[]\fR if it will be interpreted as a signed value (so that the high half can
be adjusted to match).

.IP lo16[]
Returns the low half of the value of the expression. No fixup is generated. Use of
\fBlo16[]\fR must come in the instruction immediately after a use of \fBhi16[]\fR or
\fBha16[]\fR.
