[Qemu-devel] [PATCH 00/14] preparation for autoconfy configure script

[Qemu-devel] [PATCH 00/14] preparation for autoconfy configure script

[Paolo Bonzini]

This is part two of the configure series.  It does various miscellaneous
changes to the configure script that make it possible to later handle
an autoconfy command-line.

Compared to the first submission, I simplified further the handling
of srcdir (patches 11 to 13).

Paolo Bonzini (14):
  default compilation tools to environment variables
  default make and install to environment variables
  move feature variables to the top
  fix sparse support (?)
  test cc with the complete set of chosen flags
  do not pass bogus $(SRC_PATH) include paths to cc during configure
  provide portable HOST_LONG_BITS test
  fix spelling of $pkg_config, move default together with other cross tools
  do not default to non-prefixed pkg-config when cross compiling
  reorganize sdl-config tests
  assume existence of "ln -sf"
  remove source_path_used
  move --srcdir detection earlier
  remove HOST_CC mention from roms/{sea,vga}bios/config.mak

[Qemu-devel] [PATCH 04/14] fix sparse support (?)

[Paolo Bonzini]

I didn't test with sparse, but the old code using += before a variable
was set was wrong.  Sparse support should probably be ripped out or
redone, but this at least keeps some sanity.

[Qemu-devel] [PATCH 05/14] test cc with the complete set of chosen flags

[Paolo Bonzini]

The "test the C compiler works ok" comes before a bunch of flags
are added for --cpu or just depending on the host.  It helps
debugging if the test is done after these flags are (unconditionally)
added.

[Qemu-devel] [PATCH 06/14] do not pass bogus $(SRC_PATH) include paths to cc during configure

[Paolo Bonzini]

Non-existent -I paths are dropped silently by the compiler, but still
it is not polite to pass bogus options.  Configure-time tests do not
need any include files from the source path, so only include -I flags
at make time (when they're properly expanded).

[Qemu-devel] [PATCH 07/14] provide portable HOST_LONG_BITS test

[Paolo Bonzini]

Do not hardcode the list of 64-bit CPUs.  Use sizeof(void *) to
compute it.  Renaming it to HOST_LONG_BITS to HOST_POINTER_BITS
is left for later.

The problem is not that 'ln -sf' would not exist, but rather that the
force of the '-f' flag is too weak to actually remove anything.

[Qemu-devel] [PATCH 12/14] simplify source_path handling

[Paolo Bonzini]

source_path_used is not necessary since we use mkdir -p and test -f.

Also, dirname returns "." if a path has no directory component,
as is the case for "sh configure".
