Features of the AIX® assembler

Features of AIX Assembler.

This section describes features of the AIX® assembler.

Multiple hardware architecture and implementation platform support
The assembler supports source programs containing instructions unique to any of the Power® and PowerPC® processor architectures.
Host machine independence and target environment indicator flag
The host machine is the hardware platform on which the assembler runs.
Mnemonics cross-reference
The assembler supports both PowerPC® and POWER® family mnemonics.
CPU ID definition
During the assembly process the assembler determines the smallest instruction set containing all the instructions and gives a CPU ID value indicating the instruction set.
Source language type
The assembler records the source language type.
Detection error conditions
An error is reported if the source program contains invalid instruction forms. Error occurs due to incompatibility between the POWER® family and PowerPC® architectures.
Warning messages
The warning messages are listed when the -w flag is used with the as command.
Special-purpose register changes and special-purpose register field handling
The special-purpose registers are defined in the POWER® family architecture.
