2015-08-24tcg: Split trunc_shr_i32 opcode into extr[lh]_i64_i32Richard Henderson1-1/+2
Rather than allow arbitrary shift+trunc, only concern ourselves with low and high parts. This is all that was being used anyway. Signed-off-by: Richard Henderson <rth@twiddle.net>
2015-08-24tcg: rename trunc_shr_i32 into trunc_shr_i64_i32Aurelien Jarno1-1/+1
The op is sometimes named trunc_shr_i32 and sometimes trunc_shr_i64_i32, and the name in the README doesn't match the name offered to the frontends. Always use the long name to make it clear it is a size changing op. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Richard Henderson <rth@twiddle.net>
2015-06-03tcg: add TCG_TARGET_TLB_DISPLACEMENT_BITSPaolo Bonzini1-0/+1
This will be used to size the TLB when more than 8 MMU modes are used by the target. Limitations come from the limited size of the immediate fields (which sometimes, as in the case of Aarch64, extend to instructions that shift the immediate).

2014-04-16tcg-aarch64: Reuse LR in translated codeRichard Henderson1-15/+17
