2010-02-06tcg: generic support for conditional setRichard Henderson1-0/+3
Defines setcond_{i32,i64} and setcond2_i32 for 64-on-32-bit. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2009-10-04tcg: add ext{8,16,32}u_i{32,64} TCG opsAurelien Jarno1-0/+15
Currently zero extensions ops are implemented by a and op with a constant. This is then catched in some backend, and replaced by a zero extension instruction. While this works well on RISC machines, this adds a useless register move on non-RISC machines. Example on x86: ext16u_i32 r1, r2 is translated into mov %eax,%ebx movzwl %bx, %ebx while the optimized version should be: movzwl %ax, %ebx This patch adds ext{8,16,32}u_i{32,64} TCG ops that can be implemented in the backends to avoid emitting useless register moves.

2008-12-07Some cleanups after dyngen removalaurel321-4/+0
this patch removes some now unused things after dyngen removal. 1. dyngen-exec.h: op_param, op _jmp and some associated macros are now unused; 2. Makefile.target: tcg-dyngen is not needed anymore 2. tcg/tcg-op.h, tcg/tcg-opc.h: gen-op.h is dead 3. tcg.c: - INDEX_op_end is now the first op - CONFIG_DYNGEN_OP is never defined 4. tcg.h: dyngen_op not needed anymore 5. exec-all.h: remove some ASM macros.
