Description Keith Rollin 2020-09-21 15:40:00 PDT
Factor out the common aspects of the build rules in Makefile.shared and the various Makefiles. This allows us to more easily see what's different between the various build targets, and to apply uniform changes across all of the targets.

David, I really did a number on your set-sanitizer-configuration target. I think that what remains is equivalent to what you'd been doing, but I didn't understand all of what you'd implemented, so I'm not sure.

This doesn't need to be @$(call build_target_for_each_module) as done in Makefile.shared?  Is that because we don't need to pass arguments?

I'm sorry, what does `[[ -t 1 ]]` do?!

> Makefile.shared:123
> +	@$(call set_webkit_configuration,--debug --force-optimization-level=O3)

This won't pass `--debug --force-optimization-level=O3` as a single string to the shell, will it?

Correct.

It checks to see if the specified file descriptor (in this case, stdout) is associated with a terminal.

No. I checked for that. `Make` performs a simply text replacement and then processes the resulting string.
