Merge pull request #770 from whitequark/opt_expr_cmp 
opt_expr: refactor and improve simplification of comparisons
 2019-01-02 17:34:04 +01:00
whitequark bf8db55ef3 opt_expr: improve simplification of comparisons with large constants. 
The idea behind this simplification is that a N-bit signal X being
compared with an M-bit constant where M>N and the constant has Nth
or higher bit set, it either always succeeds or always fails.

However, the existing implementation only worked with one-hot signals
for some reason. It also printed incorrect messages.

This commit adjusts the simplification to have as much power as
possible, and fixes other bugs.

whitequark 9e9846a6ea opt_expr: refactor simplification of signed X>=0 and X<0. NFCI. 2019-01-02 03:01:25 +00:00
whitequark 8e53d2e0bf opt_expr: simplify any unsigned comparisons with all-0 and all-1. 
Before this commit, only unsigned comparisons with all-0 would be
simplified. This commit also makes the code handling such comparisons
to be more rigorous and not abort on unexpected input.

Merge pull request #724 from whitequark/equiv_opt 
equiv_opt: new command, for verifying optimization passes
 2018-12-16 15:54:26 +01:00
whitequark 7ff5a9db2d equiv_opt: pass -D EQUIV when techmapping. 
This allows avoiding techmap crashes e.g. because of large memories
in white-box cell models.

Merge pull request #679 from udif/pr_syntax_error 
More meaningful SystemVerilog/Verilog parser error messages
 2018-10-25 13:18:59 +02:00
Udi Finkelstein 536ae16c3a Rename the generic "Syntax error" message from the Verilog/SystemVerilog parser into unique, 
meaningful info on the error.
Also add 13 compilation examples that triggers each of these messages.
