2009-03-29target-alpha: bug fix: avoid nop to override next instructionaurel32
While searching PC, always store the pc of a new instruction. Instructions that didn't generate tcg code (such as nop) prevented the next one to be referenced.

2008-11-18Refactor and enhance break/watchpoint API (Jan Kiszka)aliguori
This patch prepares the QEMU cpu_watchpoint/breakpoint API to allow the succeeding enhancements this series comes with. First of all, it overcomes MAX_BREAKPOINTS/MAX_WATCHPOINTS by switching to dynamically allocated data structures that are kept in linked lists. This also allows to return a stable reference to the related objects, required for later introduced x86 debug register support. Breakpoints and watchpoints are stored with their full information set and an additional flag field that makes them easily extensible for use beyond pure guest debugging.

2008-11-18Refactor translation block CPU state handling (Jan Kiszka)aliguori
This patch refactors the way the CPU state is handled that is associated with a TB. The basic motivation is to move more arch specific code out of generic files. Specifically the long #ifdef clutter in tb_find_fast() has to be overcome in order to avoid duplicating it for the gdb watchpoint fixes (patch "Restore pc on watchpoint hits").

2008-11-10target-alpha: fix cmpbge instructionaurel32
The cmpbge instruction should compare all 8 bytes of one 64-bit value with another. However, we were looping with a < 7 condition which was skipping the top byte. So if we were doing a compare where the top byte was important, we could get the wrong result (this notably breaks the strlen() function with certain sized strings).

2008-11-07target-alpha: fix locked loads/storesaurel32
Fix reading of cpu_lock in gen_qemu_stql_c, original patch from Laurent Desnogues. A new flag was added to gen_store_mem to allocate local temps instead of temps; this flag should be set when the tcg_gen_qemu_store callback uses brcond before using the temps or else liveness analysis will get rid of the temps. This also adds lock printing in cpu_dump_state which can help debug. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5645 c046a42c-6fe2-441c-8c8c-71466251a162
2008-11-06target-alpha: Fix ret instructionaurel32
Hopefully pine doesn't corrupt this patch, I've had problems recently. For an alpha "ret" instruction, of the type ret $26 The return was being ignored. This is because in translate.c register $26 (the return address) was being over-written with the current PC before it could be jumped to. Thus the ret was ignored. This patch just re-orders things so the return address is processed before it is over-written with the current PC.
