Proposed fix

Here is a proposed fix which implements: -fdump-lang-all, -fdump-lang-quad,
-fdump-lang-quad=3D, -fdump-lang-gimple, -fdump-lang-gimple=3D, -fm2-dump-f=
ilter=3D.

The filter must be a comma separated list which can take three forms: the f=
ull
decl textual name of a procedure, [libname.]module.ident or
[filename.]module.ident.

Currently it only filters on procedure names and regexp matching is not
implemented.  It would be straightforward to add regexp if required as a
followup also there could be a another option to walk the tree and dump out=
 all
dependants possibly.

An example of it usage:

$ gm2 hello3.mod -fdump-lang-all -fm2-whole-program -fm2-dump-filter=3D\
m2pim.Storage.ALLOCATE,\
m2pim.SysStorage.ALLOCATE,\
Storage_DEALLOCATE,NumberIO.HexToStr

$ ls -1r
a-hello3.mod.001l.quad
a-hello3.mod.002l.quad
a-hello3.mod.003l.quad
a-hello3.mod.002l.gimple
a-hello3.mod.001l.gimple
a-hello3.mod.004l.quad

Currently undergoing full bootstrapping testing.=
