2015-08-18target-alpha: Use separate TCGv temporaries for the shadow registersRichard Henderson6-103/+134
This avoids having to manually swap them around when swapping to and from PALmode. We simply encode the shadow registers into the translation. The VMStateDescription version changes, because the meaning of "shadow" changes in the save file when in PALmode. It would be possible to fix this, but I don't think it's worth the effort.

2015-07-09cpu: Change cpu_exec_init() arg to cpu, not envPeter Crosthwaite1-1/+1
The callers (most of them in target-foo/cpu.c) to this function all have the cpu pointer handy. Just pass it to avoid an ENV_GET_CPU() from core code (in exec.c).

2015-07-09translate-all: Change tb_flush() env argument to cpuPeter Crosthwaite1-1/+1
All of the core-code usages of this API have the cpu pointer handy so pass it in. There are only 3 architecture specific usages (2 of which are commented out) which can just use ENV_GET_CPU() locally to get the cpu pointer. The reduces core code usage of the CPU env, which brings us closer to common-obj'ing these core files.

2015-07-09cpu: Add Error argument to cpu_exec_init()Bharata B Rao1-1/+1
Add an Error argument to cpu_exec_init() to let users collect the error. This is in preparation to change the CPU enumeration logic in cpu_exec_init(). With the new enumeration logic, cpu_exec_init() can fail if cpu_index values corresponding to max_cpus have already been handed out. Since all current callers of cpu_exec_init() are from instance_init, use error_abort Error argument to abort in case of an error.

disas does not need to access the CPU env for any reason. Change the APIs to accept CPU pointers instead. Small change pattern needs to be applied to all target translate.c.

2015-03-13tcg: Change translator-side labels to a pointerRichard Henderson1-2/+2
This is improved type checking for the translators -- it's no longer possible to accidentally swap arguments to the branch functions. Note that the code generating backends still manipulate labels as int. With notable exceptions, the scope of the change is just a few lines for each target, so it's not worth building extra machinery to do this change in per-target increments.

2015-01-20exec.c: Drop TARGET_HAS_ICE define and checksPeter Maydell1-2/+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.
