This extension to Silver allows ableC extension writers to express complex ASTs by writing C code directly using its concrete syntax, instead of manually writing complex expressions over its abstract syntax. For example, the new Silver expression
ableC_Stmt {
int a = 1;
int b = 2;
return a + b;
}
is equivalent to writing
seqStmt(declStmt(variableDecls(...)), seqStmt(declStmt(variableDecls(...)), returnStmt(addExpr(...))))
This saves a tremendous amount to time for extension developers and signficantly lowers the bar to entry into these efforts.
