Sensitive list "@ *" is not recognizable #173

Closed stitchlibar closed 3 years ago

stitchlibar commented 3 years ago

The app fails on @ , Parse error: unexpected token '' (Sym_aster)

always @ * begin a = b & c; end

Other commercial tool can parse it.

Thank you for pointing this out! 77ee49a80e9ea64988dae3750c20f5912d2a17ab should fix it.

Thanks. But when I build the latest release, it takes much longer time than before. And ghc used up all CPU resources.

Unfortunately, the parser is the slowest to compile out of sv2v's modules. My only suggestion for the moment is to let it run. I wouldn't be surprised if this could take a couple minutes on certain machines. However, you seem to have been able to compile that file in the past, and the recent changes should have made the situation any worse. I will still look into this further, because the slowdown appears to be much worse with GHC 9.X, which I would eventually like to upgrade to.

Please let me know if you were able to get that build to complete! I did just push a small change which should make recompilation more efficient (fewer threads) without making it slower. I've also started looking into the GHC 9.X issue, and it appears unrelated.

This has been fixed. And compile speed is back to normal.
