2012-10-19targphys.h: Don't define target_phys_addr_t for user-mode emulatorsPeter Maydell
Commit 4be403c accidentally defined the target_phys_addr_t type when building user-mode emulators. Since the type doesn't really make any sense except for system emulators, avoid defining it when building in user mode.

2012-10-19ui/vnc: Only report/use TIGHT_PNG encoding if enabled.Joel Martin
If TIGHT_PNG is not enabled by the --enable-vnc-png configure flag then do not report to the client that it is supported. Also, since TIGHT_PNG is the same as the TIGHT encoding but with the filter/copy replaced with PNG data, adding it to the supported encodings list when it is disabled will cause the TIGHT encoding to be used even though the client requested TIGHT_PNG.

2012-10-17target-arm/translate: Fix RRX operandsPeter Crosthwaite
Instructions that both use the RRX second operand and update CS were incorrect, as the Carry flag was updated too early. An example of such an instruction would be: ands r12,r13,RRX Ands, because of the "s" flag will update the carry flag. But the RRX second operand rotates through the C flag which should happen before the update. Fixed the ordering of the two, the old carry is read by "r13,RRX" before being updated.

2012-10-17tcg: Optimize half-dead add2/sub2Richard Henderson

2012-10-17tcg: Split out swap_commutative as a subroutineRichard Henderson
Reduces code duplication and prefers movcond d, c1, c2, const, s to movcond d, c1, c2, s, const It also prefers add r, r, c over add r, c, r when both inputs are known constants. This doesn't matter for true add, as we will fully constant fold that. But it matters for a follow-on patch using this routine for add2 which may not be fully foldable.

2012-10-17tcg-ia64: Implement depositRichard Henderson
Note that in the general reg=reg,reg case we're restricted to 16-bit insertions.
