Module Name: src Committed By: rillig Date: Wed Jul 29 21:35:35 UTC 2020
Modified Files: src/usr.bin/make: var.c src/usr.bin/make/unit-tests: modmisc.exp modmisc.mk Log Message: make(1): remove unnecessary assignments to st->next No change in the size of the resulting binary. Apparently GCC already knew these assignments were redundant.
