|
|
HP-PA calling conventions state:
|
|
|
|
1. an argument relocation stub is required whenever the callee and
|
|
caller argument relocation bits do not match exactly. The exception
|
|
to this rule is if either the caller or callee argument relocation
|
|
bit are 00 (do not relocate).
|
|
|
|
2. The linker can optionally add a symbol record for the stub so that
|
|
the stub can be reused. The symbol record will be the same as the
|
|
original export symbol record, except that the relocation bits will
|
|
reflect the input of the stub, the type would be STUB and the symbol
|
|
value will be the location of the relocation stub.
|
|
|
|
Other notes:
|
|
|
|
Stubs can be inserted *before* the section of the caller. The stubs
|
|
can be treated as calls to code that manipulates the arguments.
