2013-10-10tcg-hppa: Remove tcg backendRichard Henderson
Signed-off-by: Richard Henderson <rth@twiddle.net>
2013-09-02exec: Split softmmu_defs.hRichard Henderson
The _cmmu helpers can be moved to exec-all.h. The helpers that are used from TCG will shortly need access to tcg_target_long so move their declarations into tcg.h. This requires minor include adjustments to all TCG backends. Reviewed-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Richard Henderson <rth@twiddle.net>

2012-10-06tcg: Add tcg_high_condRichard Henderson
The table that was recently added for hppa is generally usable. And with the renumbering of the TCG_COND constants it's not too difficult to compute rather than have a table. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2012-10-06tcg: Add TCG_COND_NEVER, TCG_COND_ALWAYSRichard Henderson
There are several cases that can be handled easier inside both translators and code generators if we have out-of-band values for conditions. It's easy enough to handle ALWAYS and NEVER in the natural way inside the tcg middle-end. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2012-10-06tcg: remove obsolete jmp opAurelien Jarno
The TCG jmp operation doesn't really make sense in the QEMU context, it is unused, it is not implemented by some targets, and it is wrongly implemented by some others. This patch simply removes it.

2012-09-22tcg: Remove tcg_target_get_call_iarg_regs_countStefan Weil
The TCG targets no longer need individual implementations. Since commit 6a18ae2d2947532d5c26439548afa0481c4529f9, 'flags' is no longer used in tcg_target_get_call_iarg_regs_count. The remaining tcg_target_get_call_iarg_regs_count is trivial and only called once. Therefore the patch eliminates it completely.

2012-03-18softmmu templates: optionally pass CPUState to memory access functionsBlue Swirl

2012-03-11tcg: Improve tcg_out_label and fix its usage for w64Stefan Weil
tcg_out_label is always called with a third argument of pointer type which was casted to tcg_target_long. These casts can be avoided by changing the prototype of tcg_out_label. There was also a cast to long. For most hosts with sizeof(long) == sizeof(tcg_target_long) == sizeof(void *) this did not matter, but for w64 it was wrong. This is fixed now.

2011-08-21tcg: Always define all of the TCGOpcode enum members.Richard Henderson
By always defining these symbols, we can eliminate a lot of ifdefs. To allow this to be checked reliably, the semantics of the TCG_TARGET_HAS_* macros must be changed from def/undef to true/false.

Add functions for synthetic operations: addi, mtctl, dep, shd, vshd, ori, andi, shifts, rotates, multiply, branches, setcond.
