2013-04-15tcg-ppc64: Handle deposit of zeroRichard Henderson
The TCG optimizer does great work when inserting constants, being able to fold the open-coded deposit expansion to just an AND or an OR. Avoid a bit the regression caused by having the deposit opcode by expanding deposit of zero as an AND.

2013-04-15tcg-ppc64: Use ISEL for setcondRichard Henderson
There are a few simple special cases that should be handled first. Break these out to subroutines to avoid code duplication. Reviewed-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-04-15tcg-ppc64: Use MFOCRF instead of MFCRRichard Henderson
It takes half the cycles to read one CR register instead of all 8. This is a backward compatible addition to the ISA, so chips prior to Power 2.00 spec will simply continue to read the entire CR register.

2013-04-15tcg-ppc64: Cleanup i32 constants to tcg_out_cmpRichard Henderson

2013-04-15tcg-ppc64: Use TCGType throughout comparesRichard Henderson
The optimization/bug being fixed is that tcg_out_cmp was not applying the right type to loading a constant, in the case it can't be implemented directly. Rather than recomputing the TCGType enum from the arch64 bool, pass around the original TCGType throughout.

2013-04-15tcg-ppc64: Use I constraint for mulRichard Henderson
The mul_i32 pattern was loading non-16-bit constants into a register, when we can get the middle-end to do that for us. The mul_i64 pattern was not considering that MULLI takes 64-bit inputs. Reviewed-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-04-15tpm: reorganize headers and split hardware partPaolo Bonzini
The TPM subsystem does not have a full front-end/back-end separation. The sole available backend, tpm_passthrough, depends on the data structures of the sole available frontend, tpm_tis. However, we can at least try to split the user interface (tpm.c) from the implementation (hw/tpm). The patches makes tpm.c not include tpm_int.h, which is shared between tpm_tis.c and tpm_passthrough.c; instead it moves more stuff to tpm_backend.h.

2013-04-15qemu-char: another io_add_watch_poll fixPaolo Bonzini
After attaching the source, we have to remove the reference we hold to it, because we do not hold anymore a pointer to the source. If we do not do this, removing the source will not finalize it and will not drop the "real" I/O watch source. This showed up when backporting the new flow control patches to older versions of QEMU that still used select. The whole select then failed with EBADF (poll instead will reporting POLLNVAL on a single pollfd) and QEMU froze.
