This changeset brings support for accesses like:
class Cls#(type TYPE1);
TYPE1::some_method();
endclass
It is done by delaying dot resolution on type parameters until they get
resolved by V3Param, and doing a more thorough reference skip.
Multiple tricks to reduce the size of class FileLine from 72 to 40
bytes:
- Reduce file name index from 32 to 16 bits. This still allows 64K
unique input files, which is hopefully enough.
- Intern message/warning enable bitset and use a 16-bit index, again
allowing 64K unique sets which is hopefully enough.
- Put the m_waive flag into the sign bit of one of the line numbers.
- Use explicit reference counting to avoid overhead of shared_ptr.
Added assertions to ensure interned data fits within it's index space.
This saves ~5-10% peak memory consumption at no measurable run-time cost
on various designs.
- Rename `--dump-treei` option to `--dumpi-tree`, which itself is now a
special case of `--dumpi-<tag>` where tag can be a magic word, or a
filename
- Control dumping via static `dump*()` functions, analogous to `debug()`
- Make dumping independent of the value of `debug()` (so dumping always
works even without the debug flag)
- Add separate `--dumpi-graph` for dumping V3Graphs, which is again a
special case of `--dumpi-<tag>`
- Alias `--dump-<tag>` to `--dumpi-<tag> 3` as before
Introduce the @astgen directives parsed by astgen, currently used for
the generation child node (operand) accessors. Please see the updated
internal documentation for details.
At the end of V3Param, fix up the module list to be topologically
sorted. We need to do this at the end as a later instantiation of a
recursive module might instantiate an earlier specialization, which we
cannot know until we processed everything. The rest of the compiler
depends on the module list being topologically sorted.
Fixes#3393
Rename AstNodeModule::hierName -> someInstanceName and explain that this
is only used for user messages.
Rename AstNode::locationStr -> instanceStr and simplify implementation.
In particular, do not report an instance if we can't find a reasonable
guess.
