[Qemu-devel] [RFC PATCH 0/6] Generate config_h from config.mak

[quintela@redhat.com]

From: Juan Quintela <quintela@redhat.com>

Hi

This patches apply on top of my previous series.
I generate $target_dir/config.h from $target_dir/config.mak

ToDo:
- generate config-host.h from config-host.mak
- USE_NPTL -> can I rename it to CONFIG_USE_NPTL?
- TARGET_ABI_MIPS{O32,N32,N64}.  Rest of architectures use names like:
  TARGET_ABI_MIPSN32 -> TARGET_MIPSN32
  TARGET_ABI_MIPSN64 -> TARGET_MIPSN64
  not sure how to do the TARGET_ABI_MIPSO32
  This one is only to have coherent options names, rest of architectures have
  enough with TARGET_ARCH, TARGET_ARCH2, TARGET_BASE_ARCH, TARGET_$ARCH_NAME
  TARGET_$BASE_ARCH_NAME

- TARGET_ARCH2 -> can we rename it to TARGET_SUBARCH or something more
  descriptive
- do we want TARGET_BASE_ARCH defined for .h files?
- move all CPPFLAGS/CFLAGS/LDFLAGS/LIBS to configure and export only this 4
  variables (both for config.mak and config-host.mak).  I don't think that
  this only 4 vars will be enough, but I am sure that we can export less
  than we have now.
- remove rest of intelligence (also known as ifs) possible from Makefile*
  and moved it back to ./configure
- once previous steps are done, be able to configure the devices using this
  (or similar mechanism)

Comments?

Later, Juan.


Juan Quintela (6):
  simplify TARGET_BASE_ARCH generation
  simplify TARGET_ARCH2 generation
  simplify TARGET_ABI_DIR generation
  rename s/config_mak/config_host_mak/ and s/config_h/config_host_h/
  Refactor config_softfloat selection in another list
  Generate $target_dir/config.h from $target_dir/config.mak
