redo --ifchange CC hello.c
gcc -o $3 -c hello.c
Complicate the test build a bit to show unnecessary dependency re-checking. './redo -d test' reveals that we check and re-check things like CC and LD even when they're children of objects that don't need to be rebuilt, and who we've already checked earlier in the build cycle. We need to be a little smarter about pruning if we want dependency checking to be fast. 2010-11-12 22:15:34 -08:00			`redo --ifchange CC hello.c`
