[Qemu-devel] [Bug 621780] Re: 160 unused but set variables in QEMU

[Peter Maydell]

We fixed all our unused-but-set compiler warnings some time before the
release of qemu 1.0, so I'm closing this bug as fixed.

Title:
  160 unused but set variables in QEMU

Status in QEMU:
  Fix Released

Bug description:
  I use gcc from SVN on my desktop:
  address@hidden:~/gits/qemu$ gcc -v
  Using built-in specs.
  COLLECT_GCC=gcc
  
COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/x86_64-unknown-linux-gnu/4.6.0/lto-wrapper
  Target: x86_64-unknown-linux-gnu
  Configured with: ./configure --enable-languages=c,c++
  Thread model: posix
  gcc version 4.6.0 20100726 (experimental) (GCC) 

  which enables a new warning, 'unused-but-set'.  Normally, this
  wouldn't be a big deal, just an annoyance, but since QEMU builds with
  -Werror, it causes problems.

  Easy enough to workaround with 'make -k'. To make it a bit easier on
  you, I ran 'make -k ; make -k &> make.txt', and attached that here, so
  you can easily find the 160 cases that should be fixed in qemu without
  needing gcc 4.6.
