* verilog: fix string literal regular expression.

A backslash was improperly quoted, causing string literal matching
to fail when the final token before a closing quote was an escaped
backslash.

Gary Wong 34a2abeddb verilog: fix parser "if" memory errors. 
Fix buggy memory allocation introduced in #5152:

1) clean up ast_stack to reflect AST node rearrangement when necessary,
to avoid dangling pointer;
2) call free_attr() on unused attribute list when no new syntax node is
created, to avoid leaking it.

Jannis Harder f019e44e74 verificsva: Support the followed-by operator in cover mode 
The implementation for the implication operator in cover mode actually
implements the followed-by operator, so we can re-use it unchanged.

It is not always the correct behavior for the implication operator in
cover mode, but a) it will only cause false positives not miss anything
so if the behavior is unexpected it will be visible in the produced
traces, b) it is unlikely to make a difference for most properties one
would practically use in cover mode, c) at least one other widely used
SVA implementations behaves the same way and d) it's not clear whether
we can fix this without rewriting most of verificsva.cc

Gary Wong 370d5871f4 verilog: implement SystemVerilog unique/unique0/priority if semantics. 
There are two elements involved:

1) Apply the relevant full_case and/or parallel_case attribute(s) to
the generated AST_CASE node(s), so that the existing AST frontend and
subsequent passes will generate RTLIL with appropriate behaviour.
(This is handled in the parser "if_attr" non-terminal.)

2) Rearrange the AST_CASE structure when necessary.  For "priority if"
(i.e., full_case), this requires only ensuring that directly nested
"else if" branches also inherit the full_case attribute.  For
"unique if" and "unique0 if" (i.e., parallel_case+full_case and
parallel_case alone), there are two steps:
    a) Flatten the AST_CASE structure such that any direct "else if"
    branches are mapped to additional AST_CONDs in the parent;
    b) Reverse the "direction" of the test: the constant 1 (true)
    is provided in the AST_CASE node, and the expression(s) in the
    if statement(s) are given in each AST_COND.  This is necessary
    because the constant 1, being the common factor, must occupy the
    shared AST_CASE position.
(This is handled in the parser "TOK_IF" expansion of behavioral_stmt.)

Observe that:
 * The generated AST has not been changed for bare "if"s (those
 without unique/priority).  This should minimise the risk of
 unexpected regressions.

 * It is possible that the flattening described in 2) a) above might
 affect the behaviour of expressions with side effects in "unique if"
 statements (consider "unique if( a ) ...; else if( b++ ) ...": if
 a is true, is b incremented?).  While it might be possible to provide
 precise semantics here, IEEE 1800-2012 12.4.2 seems to be deliberately
 vague ("In unique-if and unique0-if, the conditions may be evaluated
 and compared in any order[...] The presence of side effects in
 conditions may cause nondeterministic results.") and so it seems
 doubtful that there is benefit in Yosys providing stronger promises
 on the interpretation of questionable code.

 2025-05-23 15:55:45 +02:00
Gary Wong 9770ece187 Accept (and ignore) SystemVerilog unique/priority if. 
Add support to the "read_verilog -sv" parser to validate the
"unique", "unique0", and "priority" keywords in contexts where
they're legal according to 1800-2012 12.4.2.

This affects only the grammar accepted; the behaviour of conditionals
is not changed.  (But accepting this syntax will provide scope for
possible optimisations as future work.)

Three test cases ("unique_if", "unique_if_else", and
"unique_if_else_begin") verify that the keywords are accepted where
legal and rejected where illegal, as described in the final paragraph
of 12.4.2.

Update verilog_frontend.cc 
`read_verilog_file_list` should not try to read arguments as selection args.  Without this, trying to pass a file without a `-f|-F` flag is misleading, in the best case giving a warning about the selection not matching any module, or in worst case just doing nothing (if the filename is a valid selection).

Jannis Harder 0f13b55173 Liberty file caching with new `libcache` command 
This adds optional in-memory caching of parsed liberty files to speed up
flows that repeatedly parse the same liberty files. To avoid increasing
the memory overhead by default, the caching is disabled by default. The
caching can be controlled globally or on a per path basis using the new
`libcache` command, which also allows purging cached data.
