2009-05-15fix ARMv7 data processing instructionsJuha Riihimäki
ARMv7 defines a new behavior for ARM data processing instructions compared to earlier architecture revisions; when the destination register is R15, a Branch and Exchange operation is executed rather than a simple Branch to the target address. This patch corrects the behavior of the emulation for the aforementioned operations. To be applied after applying the previous patch in this patch set.

Modernize parts of target-arm/translate.c in preparation for the modifications in the subsequent patch in this patch set. This is done in order to avoid writing new code to target-arm/translate.c that would use deprecated methods and/or variables.

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").
