A host chardev could close just before the guest sends some data to be written. This will cause an -EPIPE error. This shouldn't be propagated to virtio-serial-bus. Ideally we should close the port once -EPIPE is received, but since the chardev interface doesn't return such meaningful values to its users, all we get is -1 for any kind of error. Just return 0 for now and wait for chardevs to return better error messages to act better on the return messages. Signed-off-by: NAmit Shah <amit.shah@redhat.com>

Both the signal thread (via sigwait()) and the cpu thread (via a normal signal handler) were attempting to catch SIG_IPI. This resulted in random freezes under Darwin. This patch separates SIG_IPI from the rest of the signals handled by the signal thread, because it is independently caught by the cpu thread.

Changes since v1: - take pthread_sigmask() out of the ifdef as it is now common to both parts. This fix effectively blocks, in the main thread, the signals handled by signalfd or the compatibility signal thread. This way, such signals are received synchronously in the main thread through sigfd_handler() instead of triggering the signal handler directly, asynchronously.

MIPS uses similar calling convention than ARM eabi, where when using 64-bit values some registers are skipped. This patch makes MIPS and ARM eabi share the argument reordering code. This affects ftruncate64, creating insane sized fails (or just failing). Cc: Wesley W. Terpstra <terpstra@debian.org> Signed-off-by: NRiku Voipio <riku.voipio@linaro.org>

As reported by Cédric VINCENT: The syscall #123 on SH4 should be "TARGET_NR_cacheflush" instead of "TARGET_NR_modify_ldt" [1]. The only consequence of this misnaming is that many "Unsupported syscall" warnings are issued when emulating JIT compilers.

Recent compilers look deep into cpu_exec, find longjmp as a noreturn function and decide to smash some stack variables as they won't be used again. This may lead to env becoming invalid after return from setjmp, causing crashes. Fix it by reloading env from cpu_single_env in that case.

The target-arm frontend's worst-case TCG ops per instr is 194 (and in general many of the "load multiple registers" ARM instructions generate more than 100 TCG ops). Raise MAX_OP_PER_INSTR accordingly to avoid possible buffer overruns. Since it doesn't make any sense for the "64 bit guest on 32 bit host" case to have a smaller limit than the normal case, we collapse the two cases back into each other again. (This increase costs us about 14K in extra static buffer space and 21K of extra margin at the end of a 32MB codegen buffer.)

When calculating the point at which we should not try to put another TB into the code gen buffer, we have to allow not just for OPC_MAX_SIZE but OPC_BUF_SIZE. This is because the target translate.c will only stop when an instruction has put it past the OPC_MAX_SIZE limit, so we have to include the MAX_OP_PER_INSTR margin which that final insn might have used.
