tokens: fix parallel builds
|
|
|
|
Currently, tokens.h and token_vars.h are each generated by a call to
|
|
mktokens, which means mktokens is called twice.
|
|
|
|
But mktokens generates both in a single run.
|
|
|
|
This means that, with a fast-enough machine, the call to mktokens that
|
|
generates tokens.h may finish before the call that generates
|
|
token_vars.h. Then tokens.h is transiently incomplete (it can even be
|
|
empty). By the time it is fully generated in the second run, a compile
|
|
job that ends up using token.h may have already started, and the source
|
|
file would include an in complete token.h and would be missing some
|
|
token definitions.
|
|
|
|
We fix that by making token.h a dependency of token_vars.h, with a
|
|
dummy recipe (to force it not being PHONY). The actual recipe is for
|
|
token_vars.h
