Re: [PATCH] Support SPARSE in Makefile, better SPARSE_FLAGS

I know.  That's what I'm using in the wrapper (plus -m64 and some
warnings).  But it should be the default.  Until then, hassle-free
sparse support in the Makefile is only possible for the projects that
already know the architecture (e.g. the Linux kernel).

I think that's debatable.  It introduces main-compiler dependencies into
sparse which is undesirable.

I see sparse is already moving in this direction.  Right now, it's somewhere in
the middle, which is quite inconvenient.  It hardcodes gcc version numbers but
not the architecture.

A much simpler option would be to write a "sparsegcc" script which would
be invoked just like gcc, extract the appropriate macro information
based on options, and then invoke sparse.

I guess that's what cgcc is trying to be.  Since it also runs the compiler, no
special support for cgcc should be needed in Makefile other than using $(CC).
