Hi; I'm afraid this fails to build for me when building
m68k-linux-user:
/root/qemu/linux-user/signal.c: In function 'target_rt_restore_ucontext':
/root/qemu/linux-user/signal.c:5079:5: error: 'err' may be used
uninitialized in this function [-Werror=uninitialized]
because the function never sets 'err' but then
returns it.
(32-bit, ARM, gcc 4.7.2. I don't know why the other
compilers don't spot this; perhaps they inline the
function and then figure out that the unused return
value isn't actually ever used.)
thanks
