simplify.cc: Fix mem leak 2025-05-10 17:10:47 +12:00
KrystalDelusion 547382504b
Update verilog_frontend.cc 
`read_verilog_file_list` should not try to read arguments as selection args.  Without this, trying to pass a file without a `-f|-F` flag is misleading, in the best case giving a warning about the selection not matching any module, or in worst case just doing nothing (if the filename is a valid selection).

Jannis Harder 0f13b55173 Liberty file caching with new `libcache` command 
This adds optional in-memory caching of parsed liberty files to speed up
flows that repeatedly parse the same liberty files. To avoid increasing
the memory overhead by default, the caching is disabled by default. The
caching can be controlled globally or on a per path basis using the new
`libcache` command, which also allows purging cached data.

simplify: Skip AST_PRIMITIVE in AST_CELLARRAY 
Otherwise the `AST_PRIMITIVE` simplifies to the corresponding function and is no longer caught by the check for `AST_PRIMITIVE`s, raising an assertion error instead of an input error.
Add bug4785.ys to tests/verilog to demonstrate.

aiger2: Resolve warnings 
- Remove unused statics CONST_FALSE and CONST_TRUE (which appear to have been folded into the `Index` declaration as CFALSE and CTRUE).
- Assign default value of EMPTY_LIT to `a` and `b` for comparison ops.
- Tag debug only variables with YS_MAYBE_UNUSED, don't assign unused variables (but continue to call the function because it moves the file pointer).

Reduce comparisons of size_t and int 
`Const::size()` returns int, so change iterators that use it to `auto` instead of `size_t`.
For cases where size is being explicitly cast to `int`, use the wrapper that we already have instead: `Yosys::GetSize()`.
