'val
are used in the target of a signal assignment statement (#908). - Signals in packages are now dumped to the FST file (#901).

1.12.2
This is a minor release with an important compatibility fix for the latest LLVM version.

This is a minor bug fix release fixing the following issues:
- Fixed a crash when a process contains a
force
orrelease
assignment inside aprocess (all)
statement (#877). - Fixed a crash creating a waveform dump with

process (all)
assigns to a signal (#882). - Added a missing check for illegal assignment to external signal name outside a process (#884).
- Fixed a crash while printing diagnostic information when the simulation delta cycle limit is reached (#885).
