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.

2014-05-14savevm: Remove all the unneeded version_minimum_id_old (rest)Juan Quintela1-2/+0
After previous Peter patch, they are redundant. This way we don't assign them except when needed. Once there, there were lots of case where the ".fields" indentation was wrong: .fields = (VMStateField []) { and .fields = (VMStateField []) { Change all the combinations to: .fields = (VMStateField[]){ The biggest problem (appart from aesthetics) was that checkpatch complained when we copy&pasted the code from one place to another.

2014-04-17target-alpha: Remove cpu_unique, cpu_sysval, cpu_uspRichard Henderson1-19/+18
Technically, these variables could have been referenced both via offsets from env and as TCG registers, which would be illegal. Of course, that could only be done from PALcode, and ours doesn't do that. But honestly, these are used infrequently enough that they don't really need to be TCG registers. We wind up with exactly the same code if we follow the letter of the law and issue explicit ld/st. Signed-off-by: Richard Henderson <rth@twiddle.net>
