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
