Zachary Snow	52197df325	add bugpoint mode ... This mode reduces the size of test cases that encounter conversion errors or produce incorrect output. The logic developed slowly over the past three years. It is in a state that I find useful when fielding bug reports, but has some room for improvement in terms of constraints and filtering.	2024-06-19 23:06:34 -04:00

Zachary Snow	306d71334b	refactor sizing and truncation of integer literals ... - use iverilog's -gstrict-expr-width throughout test suite - add warnings for excess bits or padding zeroes in number literals - add new --oversized-numbers parameter to retain support for unsized numbers wider than 32 bits - localized use of oversized numbers to new truncate test suite which verifies the behavior of both modes, and compares against the known behavior of iverilog	2021-08-09 22:10:29 -06:00
