Support for injecting custom toolchain features #591
Description
There are situations where it is helpful to implement a toolchain feature for all toolchains that your project supports.
In our case, this was used for implementing different warning levels/groups that is compiler agnostic.
That allows us to have something like:
cc_library(
name = "foo",
srcs = ["foo.cpp"],
hdrs = ["foo.h"],
features = [
"safety_related_warnings",
],
)
cc_library(
name = "bar",
srcs = ["bar.cpp"],
hdrs = ["bar.h"],
features = [
"security_related_warnings",
],
)The main question for the maintainers would be, are you interested in that feature? Do you see this as something that we could add to toolchains_llvm? If yes just add a comment here and I would start working right away.
