* cpu-exec: Purge all uses of ENV_GET_CPU()Peter Crosthwaite2015-07-091-1/+1
| | | | | | | | | | | | | | | | Remove un-needed usages of ENV_GET_CPU() by converting the APIs to use CPUState pointers and retrieving the env_ptr as minimally needed. Scripted conversion for target-* change: for I in target-*/cpu.h; do sed -i \ 's/\(^int cpu_[^_]*_exec(\)[^ ][^ ]* \*s);$/\1CPUState *cpu);/' \ $I; done Signed-off-by: Peter Crosthwaite <crosthwaite.peter@gmail.com> Signed-off-by: Andreas Färber <afaerber@suse.de>

* exec.c: Drop TARGET_HAS_ICE define and checksPeter Maydell2015-01-201-2/+0
| | | | | | | | | | | | | | The TARGET_HAS_ICE #define is intended to indicate whether a target-* guest CPU implementation supports the breakpoint handling. However, all our guest CPUs have that support (the only two which do not define TARGET_HAS_ICE are unicore32 and openrisc, and in both those cases the bp support is present and the lack of the #define is just a bug). So remove the #define entirely: all new guest CPU support should include breakpoint handling as part of the basic implementation.

* cpu: Move breakpoints field from CPU_COMMON to CPUStateAndreas Färber2014-03-131-1/+2
