2012-10-19configure: Fix CONFIG_QEMU_HELPERDIR generationJan Kiszka
We need to evaluate $libexecdir in configure, otherwise we literally end up with "${prefix}/libexec" instead of the absolute path as CONFIG_QEMU_HELPERDIR. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2012-10-19qemu-options.hx: Change from recommending '?' to 'help'Peter Maydell
Update the -help output and documentation so that it recommends 'help' rather than '?' for the various "list valid values for this option" cases. '?' is deprecated (as it can fail confusingly if not quoted), so it's better to steer users towards 'help'. ('?' still works, for backwards compatibility.) This is the -help option part of the change otherwise done in commit c8057f9, since we are now past release 1.2 and free to change our help text without worrying about breaking libvirt.

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: 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.
