[Qemu-devel] [PATCH v3] qapi: Reduce Makefile boilerplate
Posted by Eric Blake 6 years, 10 months ago 
Adding a new qapi module had some rather tedious repetition to
wire it into Makefile, Makefile.objs, and .gitignore (for example,
see commit bf42508f and its followup b61acdec). For make, add some
indirection by taking advantage of GNU Make string processing to
expand a list of module names into all the required artifacts, so
that future additions of a new module need only touch the list of
module names.  And for gitignore, use globs to cover all generated
file names.

The list has to live in Makefile.objs, due to the way that
our unnest-vars macro slirps in that file without remembering
any definition of $(QAPI_MODULES) from Makefile.

v3: also tweak .gitignore [Dan]
v2: also condense Makefile.objs, prefer $(FOO:%=a%b) over
$(patsubst %,a%b,$(FOO))
