williamzhu17	bbd132f6ba	updated extract_reduce to not consider xnors	2025-04-01 10:10:06 -07:00
Jannis Harder	bc01468c75	read_liberty: Faster std::string construction in the liberty lexer ... This extends the `LibertyInputStream` added in the previous commit to allow arbitrary lookahead. Then this uses the lookahead to find the total length of the token within the input buffer, instead of consuming the token byte by byte while appending to a std::string. Constructing the std::string with the total length is known avoids any reallocations from growing std::string's buffer.	2025-04-01 14:12:12 +02:00
Jannis Harder	119e998f12	read_liberty: Faster input handling for the liberty lexer ... The lexer for liberty files was using istream's `get` and `unget` which are notorious for bad performance and that showed up during profiling. This replaces the direct `istream` use with a custom LibertyInputStream that does its own buffering to provide `get` and `unget` that behave the same way but are implemented with a fast path that is easy to inline and optimize.	2025-04-01 14:12:12 +02:00

Sean Luchen	23f59e0196	Support array ranges for identifiers in the Liberty parser. ... This change only handles the case `id : id[range] ;`.	2025-03-31 10:54:00 -07:00
Sean Luchen	ac1033ecd5	Factor parse_vector_range out into its own function. ... This also fixes the parsing a bit. It was consuming 1 fewer token than required.	2025-03-31 10:46:18 -07:00
