Description Dmitry Selyutin 2023-01-23 20:03:13 GMT
In order to allow clean and conscious versions for some algorithms, a proper label support is required. This would likely require two-stage assembly passes. We used to emulate labels in some tests or hard-code the branch locations; the time has come to support labels in a proper way.
Comment 1 Luke Kenneth Casson Leighton 2023-01-23 21:35:09 GMT
this should not be part of ISACaller because ISACaller is
a Simulator, not an Assembler Pre-Processor  it is binutils-like.
a separate function must be provided that can be used
(not part of ISACaller) if one is to be provided at all.

can you please cross-reference this bugreport to something so that
it is not "lost in noise". the ongoing nlnet milestone would do
in a pinch.  likewise the other one.
