2012-10-08net: consolidate NetClientState header files into onePaolo Bonzini
This patch doesn't seem much useful alone, I must admit. However, it makes sense as part of the upcoming directory reorganization, where I want to have include/net/tap.h as the net<->hw interface for tap. Then having both net/tap.h and include/net/tap.h does not work. "Fixed" by moving all the init functions to a single header file net/clients.h. The patch also adopts a uniform style for including net/*.h files from net/*.c, without the net/ path.

2012-10-08rtl8139: implement 8139cp link statusJason Wang
Add a link status chang callback and change the link status bit in BMSR & MSR accordingly. Tested in Linux/Windows guests. The link status bit of MediaStatus is infered from BasicModeStatus, they are inverse. nc.link_down could not be migrated, this patch updates link_down in rtl8139_post_load() to keep it coincident with real link status.

Commit 1d31fca470648ec66afd8743491bfb5846306341 tried to fix bug introduced by 610b823ef66b993660f1ab1447a769f190e4f3b3 by including qemu-common.h, which breaks the build further. Include compiler.h instead, as suggested by Blue Swirl. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2012-10-07target-sparc: Optimize conditionals using SUBCCRichard Henderson
Aka "normal" comparisons. We now have the infrastructure to pass back non-boolean results from gen_compare. This will automatically get used by both branches and conditional moves. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-07target-sparc: Fall through from not-taken trapRichard Henderson
Now that we've cleaned up global temporary allocation, we can continue translating the fallthru path of a conditional trap. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-07target-sparc: Cleanup "global" temporary allocationRichard Henderson
There are 6 temporaries that disas_sparc_insn relies on having been allocated. Now that they are no longer referenced across branches, they need not be allocated as local temps. Move the allocation/free of these temporaries to make it clear that they are local to the translation of a single insn.

2012-10-07target-sparc: Move taddcctv and tsubcctv out of lineRichard Henderson

2012-10-07target-sparc: Tidy TccRichard Henderson
Share more code between unconditional and conditional paths. Move the computation of the trap number into the conditional BB; avoid using temporaries that have gone out of scope (cpu_tmp32) or rely on local temps (cpu_dst). Fully fold the exception number when the trap number is %g0+imm. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-10-07tcg: Remove redundant pointer from TCGContextStefan Weil

Commit 610b823ef66b993660f1ab1447a769f190e4f3b3 uses QEMU_GNUC_PREREQ on i386 hosts. That macro is defined in qemu-common.h which is not always included before qemu-barrier.h, so compilation on i386 hosts was broken.
