- Implement the visitor interface. This simplifies working with the AST, for example transformations into other IRs or collecting and analyzing various statistics. - Switch the explorer to use the visitor interface. - Add the reciprocal function name conversion for function names. - Some drive-by cosmetic fixes. --------- Signed-off-by: xermicus <bigcyrill@hotmail.com>
revive-explorer
The revive-explorer is a helper utility for exploring the compilers YUL lowering unit.
It analyzes a given shared objects from the debug dump and outputs:
- The count of each YUL statement translated.
- A per YUL statement break-down of bytecode size contributed per.
- Estimated
yul-phasercost parameters.
Example:
