phsauter 3618294bac peepopt: Add assert of consistent `shiftadd` data 2023-11-06 16:35:00 +01:00
Philippe Sauter b6df900bcc peepopt: Describe `shiftadd` rule in help message 2023-11-06 14:01:37 +01:00
phsauter 9ca57d9f13 peepopt: fix and refactor `shiftadd` 
- moved all selection and filtering logic to the match block
- applied less-verbose code suggestions
- removed constraint on number of bits in shift-amount
- added check for possible wrap-arround in the operation

Martin Povišer aa9b86aeec peepopt: Add left-shift 'shiftmul' variant 
Add a separate shiftmul pattern to match on left shifts which implement
demuxing. This mirrors the right shift pattern matcher but is probably
best kept separate instead of merging the two into a single matcher.
In any case the diff of the two matchers should be easily readable.

Martin Povišer 038a5e1ed4 peepopt: Support shift amounts zero-padded from below 
The `opt_expr` pass running before `peepopt` can interfere with the
detection of a shiftmul pattern due to some of the bottom bits of the
shift amount being replaced with constant zero. Extend the detection to
cover those situations as well.

No functional change intended.

Martin Povišer a0c3be3aae peepopt: Drop unused 'initbits' code 
Drop code that was once used by the 'dffmux' pattern but now is unused
after that pattern has been obsoleted by the 'opt_dff' pass.

KrystalDelusion 9465b2af95 Fitting help messages to 80 character width 
Uses the regex below to search (using vscode):
	^\t\tlog\("(.{10,}(?<!\\n)|.{81,}\\n)"\);

Finds any log messages double indented (which help messages are)
and checks if *either* there are is no newline character at the end,
*or* the number of characters before the newline is more than 80.

Marcelina Kościelnicka cf60699884 synth_ice40: Use opt_dff. 
The main part is converting ice40_dsp to recognize the new FF types
created in opt_dff instead of trying to recognize the mux patterns on
its own.

The fsm call has been moved upwards because the passes cannot deal with
$dffe/$sdff*, and other optimizations don't help it much anyway.

whitequark c8c3c7af87 Use [[maybe_unused]] instead of YS_ATTRIBUTE(unused). 
[[maybe_unused]] is available since C++17, so this commit adds
a polyfill YS_MAYBE_UNUSED. Once we require C++17 we can drop it.
