2011-06-03tcg: Fix unused-but-set-variable warningChristophe Fergeau
Based on a patch from Hans de Goede <hdegoede@redhat.com> This warning is new in gcc 4.6. Acked-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Christophe Fergeau <cfergeau@redhat.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-06-03tcg: If DEBUG_TCGV, distinguish TCGv_ptr from TCGv_i32/TCGv_i64Peter Maydell
When compiling with DEBUG_TCGV enabled, make the TCGv_ptr type distinct from TCGv_i32/TCGv_i64. This means that using an i32 or i64 TCG op to manipulate a TCGv_ptr will always be detected at compile time, rather than only if compiling on a host system with the other word size. NB: the tcg_add_ptr and tcg_sub_ptr macros have been removed as they were not used anywhere.

2011-06-03tcg/tcg-op.h: Fix prototypes for ld/st functions on 64 bit hostsPeter Maydell
The prototypes for the ld/st functions on a 64 bit host declared the address parameter as a TCGv_i64 rather than a TCGv_ptr. This worked OK (since the two are aliases), but needs to be fixed to allow extension of TCG type debugging to i64/i32/ptr mismatches.

2011-06-03s390x: fix cksm instructionAlexander Graf
The cksm instruction was implemented incorrectly, rendering UDP and TCP checksum calculation wrong, making an emulated s390x Linux guest break in most networking operations. This patch fixes odd end checksum calculation, takes the input register as input for the checksum and optimizes the overflow pieces by a bit. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-06-03s390x: free tmp explicitly in every opcode for disas_a5()Alexander Graf
The disas_a5() function provided a TCG tmp variable which was populated by the respective opcode implementations, but freed at the end of the function in generic code. That makes it really hard for code review, so let's move the freeing to the same scope as the actual allocation. Signed-off-by: Alexander Graf <agraf@suse.de>

2011-05-27virtio-serial: Clean up virtconsole detectionMarkus Armbruster
virtio-serial-bus needs to treat "virtconsole" devices specially. It uses VirtIOSerialPort member is_console to recognize them. It gets its value via property initialization. Cute hack, except it lets users mess with it: "-device virtconsole,is_console=0" isn't plugged into port 0 as it should. Move the flag to VirtIOSerialPortInfo.
