The pseudo operation: 1) symbol@h 2) symbol@ha 2) symbol@l and those for 64bit PowerPc architecture family are not documented. Those pseudo operation are used usually in a macro for loading and immediate operand of 32bit (or 64bit) into a machine register because it is not possible to do that with a single instruction on a RISC processor. Let me point out that analogous features are documented, for example, in the case of the V850 processor, so I really think that the same should be done for the PowerPc. Many thanks
These aren't pseudo-ops as such. These are part of the assembly language syntax which is not normally documented in the GAS manual for each target. This documentation can be obtained elsewhere. However, you may submit a patch. :-) Cheers, Ben
