Subject: [PATCH] gccrs: Minor tuning in AST dump
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Use parentheses to remove any ambiguities when dumping expressions with
unary ! and -.

gcc/rust/ChangeLog:
	* ast/rust-ast-dump.cc (Dump::visit): print parentheses around
	unique expression operand.
