.bss
.bss
section.
.ltorg
GAS
maintains a separate literal pool for each section and each
sub-section. The .ltorg
directive will only affect the literal
pool of the current section and sub-section. At the end of assembly
all remaining, un-empty literal pools will automatically be dumped.
Note - older versions of GAS
would dump the current literal
pool any time a section change occurred. This is no longer done, since
it prevents accurate control of the placement of literal pools.
.pool
.req
register namefoo .req w0
.unreq
alias-namereq
directive. For example:
foo .req w0 .unreq foo
An error occurs if the name is undefined. Note - this pseudo op can be used to delete builtin in register name aliases (eg 'w0'). This should only be done if it is really necessary.
