Vl-stmt-atomicstmts

(vl-stmt-atomicstmts x) returns a flat list of all atomic statements in the statement x.

Signature

(vl-stmt-atomicstmts x) → stmts

Arguments

x — Guard (vl-stmt-p x).

Returns

stmts — Type (and (vl-stmtlist-p stmts) (vl-atomicstmtlist-p stmts)).

This is sometimes useful to avoid needing to write a mutually recursive function to walk over statements. For instance, if you want to look at all of the assignments anywhere within a statement, you can first grab all of the atomic statements, then filter it down to just the assignments, then process them.
