2013-08-29tcg-i386: Remove abort from GETPC_LDSTRichard Henderson
Indeed, remove it entirely and remove the is_tcg_gen_code check from GETPC_EXT. Fixes https://bugs.launchpad.net/qemu/+bug/1218098 wherein a call to a "normal" helper function performed a sequence of tail calls all the way into the memory helper functions, leading to a stack frame in which the memory helper function appeared to be called directly from tcg.

2013-08-27gtk: Remove unused include statements which are not portableStefan Weil
These include files don't exist for MinGW and are not needed for Linux (and hopefully for other hosts as well), so remove them. Signed-off-by: Stefan Weil <sw@weilnetz.de>

2013-08-27w32: Fix broken out-of-tree builds (missing version.o)Stefan Weil
Commit 0b516ef0dfad9a7b34c675c98e8ec92ab4d38466 added version.o to all executables, but broke out-of-tree builds: for those builds the pattern rule %.o: %.rc from rules.mak does not match, so version.o was no longer built. Adding explicit build rules fixes this. Reported-by: Michael Roth <mdroth@linux.vnet.ibm.com> Signed-off-by: Stefan Weil <sw@weilnetz.de> Tested-by: Michael Roth <mdroth@linux.vnet.ibm.com>
2013-08-26tcg-i386: Use new return-argument ld/st helpersRichard Henderson
Discontinue the jump-around-jump-to-jump scheme, trading it for a single immediate move instruction. The two extra jumps always consume 7 bytes, whereas the immediate move is either 5 or 7 bytes depending on where the code_gen_buffer gets located. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-08-26tcg: Tidy softmmu_template.hRichard Henderson
Avoid a loop in the tlb_fill path; the fill will either succeed or generate an exception. Inline the slow_ld/st function; it was a complete copy of the main helper except for the actual cross-page unaligned code, and the compiler was inlining it anyway. Add unlikely markers optimizing for the most common case of simple tlb miss. Make sure the compiler can optimize away the unaligned paths for a 1 byte access. Reviewed-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-08-26tcg: Add mmu helpers that take a return address argumentRichard Henderson
Allow the code that tcg generates to be less obtuse, passing in the return address directly instead of computing it in the helper. Maintain the old entrance point unchanged as an alternate entry point. Delete the helper_st*_cmmu prototypes; the implementations did not exist. Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-08-26tcg-i386: Tidy qemu_ld/st slow pathRichard Henderson
Use existing stack space for arguments; don't push/pop. Use less ifdefs and more C ifs. Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-08-26tcg: Tidy generated code for tcg_outNRichard Henderson
Aliasing was forcing s->code_ptr to be re-read after the store. Keep the pointer in a local variable to help the compiler. Signed-off-by: Richard Henderson <rth@twiddle.net>

2013-08-25virtio: virtqueue_get_avail_bytes: fix desc_pa when loop over the indirect ↵yinyin
descriptor table virtqueue_get_avail_bytes: when found a indirect desc, we need loop over it. /* loop over the indirect descriptor table */ indirect = 1; max = vring_desc_len(desc_pa, i) / sizeof(VRingDesc); num_bufs = i = 0; desc_pa = vring_desc_addr(desc_pa, i); But, It init i to 0, then use i to update desc_pa. so we will always get: desc_pa = vring_desc_addr(desc_pa, 0); the last two line should swap.

For compatibility, maintain an apparent bug where when using icount, if no vm_clock timer was set, qemu_clock_deadline would return INT32_MAX and always set an icount clock expiry about 2 seconds ahead.
