[Qemu-devel] [RFC PATCH v5 0/6] Shared Library Module Support

[Fam Zheng]

This series implements feature of shared object building as described in:

http://wiki.qemu.org/Features/Modules

It's achieved in three steps, with extra bonus to change curl and qed to shared
library modules in the end (only to demonstrate the usage, no "make install"
support of .so files yet).

v5: Keep foo.mo-objs idea for module objects.
    Unnest block-obj-m and common-obj-m in Makefile.target.
    Move add-modules to unnest-vars to be reused in Makefile.target.
    Use /dev/null to replace realpath for expand-objs.

v4: Added --enable-modules in the end of series.
    Make nested-vars and obj-base as arguemnts to unnest-vars.
    Take Paolo's idea in comments for v2 and switch back module objects syntax
    to:
        $(obj)/foo.mo : $(addprefix $(obj)/, bar.o biz.o qux.o)

    because this needs less duplication among Makefiles.

Fam Zheng (6):
  make.rule: fix $(obj) to a real relative path
  rule.mak: allow per object cflags and libs
  Makefile: introduce common-obj-m and block-obj-m for DSO
  module: implement module loading function
  configure: introduce --enable-modules
  block: build qed and curl as shared library
