[Qemu-devel] [PATCH 00/14] More gcc 4.6 warnings fixes

[Juan Quintela <quintela@redhat.com>]

Hi

This series fixes compilation of plain:

./configure

with gcc-4.6.0 on Fedora 15.

Notes:
- linuxload.c: why it define id_change if it never test its value?
  git log shows that it has been this way forever
- linux-user/syscall.c: do we want to return an error in the default case?
  my guess is yes, but ...
- mips: it puts 8 arguments on the stack, but do_syscall() only uses 6.
  at least some syscalls uses already 7 arguments, I guess this has never worked before.

- for this kind of warnings, I have added:
   (void)unused_var;
  We can remove the variable altogether, comment it, use __attribute__(no_warn_unused).

- linux-user, syscall for alpha.  can anyone check tat my s/arg1/how/
  is the right change.  Looking at the normal sigprocmask call
  emulation, it looks like my change is wright, but one never knows.

Later, Juan.


Juan Quintela (14):
  kvm: remove fop write only variable
  tcg: define and set call_type only when it is used
  flatload: memp was a write-only variable
  xen: pentry is not used in this function
  linuxload: id_change was a write only variable
  flatload: end_code was only used in a debug message
  alpha: fn2 was a write only variable
  syscall: really return ret code
  exec: last_first_tb was only used in !ONLY_USER case
  mips: we really need the extra arguments
  linux-user: fpu_save_addr is not used
  linux-user: syscall should use sanitized arg1
  alpha: disp12 is not used for USER emulation
  lsi53c895a: current_dev is not used
