[Qemu-devel] [PATCH v4 0/4] configure: clang 3.5.0 build fixes

[John Snow <jsnow@redhat.com>]

QEMU does not compile cleanly under clang 3.5.0.  These patches eliminate the
avalanche of warnings and make the build usable.

v4:
- Enable ccache workaround for configurations without -Werror,
  to suppress warnings as well.
- Removed optimization from cc_has_warning_flag()
- Renamed ccache variable to ccache_cpp2

v3:
- Drop tricore patch, it's already being worked on elsewhere.
- Factor out flag check test.

v2:
 - Stole the series from Stefan
 - No changes to the -nopie patch, which I think was fine.
 - Fixed the -Wno-unknown-attributes patch.
 - Added a tricore fix for -Wabsolute-value
 - Added a workaround to help suppress ccache warnings

The result is that you *should* be able to use clang 3.5.0 *with* ccache and
-Werror and produce all targets.

John Snow (3):
  configure: factor out supported flag check
  configure: silence glib unknown attribute __alloc_size__
  configure: Add workaround for ccache and clang

Stefan Hajnoczi (1):
  configure: handle clang -nopie argument warning
