GNU Assembler 7–5
GAS and GLD Programming Considerations
You can use one or more of the following options:
The Alpha 21164 microprocessor family does not support any options for this
instruction.
The following table describes the arguments:
• hw_rei
hw_rei
This instruction generates a return from PALmode through the exception address
IPR.
• hw_rei_stall
hw_rei_stall
This instruction is the same as hw_rei except that it inhibits Istream fetch until the
hw_rei itself is issued.
This command applies only to the Alpha 21164 microprocessor family.
7.4 GAS and GLD Programming Considerations
If you create multiple object files that need to be linked together to build your image,
you want to avoid certain pitfalls.
The role of the linker (GLD) is to concatenate object files and resolve references
across object files. Thus, if you have multiple files that require explicit placement of
their code, you must perform a monolithic assembly of those object files.
Option Field Description
p PAL References a PAL_TEMP register
a ABX References an Abox register
i IBX References an Ibox register
Argument Description
ra Source
rc Index into the appropriate internal processor register set, or, for the
21164 microprocessor family, an index of the desired IPR
