Marcelina Kościelnicka ef4ddfacf3 github actions: Test on several gcc and clang versions on Linux. 
Fixes #2776.

Marcelina Kościelnicka df2b79ca76 memory_share: Use Mem helpers. 2021-05-23 23:16:12 +02:00
Marcelina Kościelnicka afd5366fc2 extract_rdff: Add initvals parameter. 
This is not used yet, but will be needed when read port reset/initial
value support lands.

Marcelina Kościelnicka 33513d923a btor: Use is_mem_cell in one more place. 2021-05-23 20:34:52 +02:00
Marcelina Kościelnicka d905990d01 memory_share: Split off feedback path finding as a separate pass. 
memory_share is actually three passes in a trenchcoat.  Split off the
one that has the least in common with the other two as a separate pass.

Marcelina Kościelnicka c4cc888b2c kernel/rtlil: Extract some helpers for checking memory cell types. 
There will soon be more (versioned) memory cells, so handle passes that
only care if a cell is memory-related by a simple helper call instead of
a hardcoded list.

Rupert Swarbrick 3421979f00 Change the type of current_module to Module 
The current_module global is needed so that genRTLIL has somewhere to
put cells and wires that it generates as it makes sense of expressions
that it sees. However, that doesn't actually need to be an AstModule:
the Module base class is enough.

This patch should cause no functional change, but the point is that
it's now possible to call genRTLIL with a module that isn't an
AstModule as "current_module". This will be needed for 'bind' support.

Rupert Swarbrick 51ed4a7149 Use range-based for loop in AST::process 
No functional change: just get rid of the explicit iterator and
replace (*it)-> with child->. It's even the same number of characters,
but is hopefully a little easier to read.

Clarify bugpoint documentation regarding output

Clarify bugpoint documentation regarding output 
Bugpoint's current documentation does specify that the result of a run is stored as the current design,
however it's easy to skim over what that means in practice. 

Add a documentation comment to explain specifically that an after bugpoint `write_xyz` pass is required to save
the reduced design.
