◆ buildNLA()
|
static |
Make an anchor for a non-local annotation.
Use the expanded path to build the module and name list in the anchor.

◆ drop()
| LogicalResult drop | ( | const AnnoPathValue & | target, |
| DictionaryAttr | anno, | ||
| ApplyState & | state | ||
| ) |
Just drop the annotation.
This is intended for Annotations which are known, but can be safely ignored.
Definition at line 231 of file LowerAnnotations.cpp.
◆ getAnnotationHandler()
|
static |
Lookup a record for a given annotation class.
Optionally, returns the record for "circuit.missing" if the record doesn't exist.
Definition at line 526 of file LowerAnnotations.cpp.
References circt::firrtl::annotationRecords.
◆ getAnnotationsFrom()

◆ stdResolveImpl()
|
static |
Implementation of standard resolution.
First parses the target path, then resolves it.
