2016-03-01tcg: Add type for vCPU pointersLluís Vilanova
Adds the 'TCGv_env' type for pointers to 'CPUArchState' objects. The tracing infrastructure later needs to differentiate between regular pointers and pointers to vCPUs. Also changes all targets to use the new 'TCGv_env' type instead of the generic 'TCGv_ptr'. As of now, the change is merely cosmetic ('TCGv_env' translates into 'TCGv_ptr'), but that could change in the future to enforce the difference. Note that a 'TCGv_env' type (for 'CPUState') is not added, since all helpers currently receive the architecture-specific pointer ('CPUArchState').

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 Henderson
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.

Remove the custom qemu_assert() function defined by target-m68k/translate.c in favour of either using glib g_assert_not_reached() (for the genuinely can't-happen cases) or cpu_abort() (for the "this isn't implemented", in line with other unimplemented cases in the target). This has the benefit of silencing some clang warnings about variables used while uninitialized (which are emitted because clang can't figure out that qemu_assert(0, something) never returns.
