- Subject: Go patch committed: Don't generate range value for sink
This patch from Chris Manghane fixes a bug when the value in a range
clause is a sink variable. It's fixedbugs/bug454.go in the master Go
testsuite, and will appear in the gccgo testsuite in due course.
Bootstrapped and ran Go testsuite on x86_64-unknown-linux-gnu.
Committed to mainline and 4.8 branch.
