2009-10-04tcg: add ext{8,16,32}u_i{32,64} TCG opsAurelien Jarno
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.

2009-04-13Add a --enable-debug-tcg option to configureaurel32
This patch allows DEBUG_TCGV to be defined (and also prevents NDEBUG from being defined) when passing an option to the configure script. This should help to prevent any accidental changes that enable DEBUG_TCGV in tcg/tcg.h from being committed in future, and may help to encourage testing with DEBUG_TCGV enabled.

2009-04-06tcg: add a CONST flag to TCG helpersaurel32

2009-04-05tcg/x86_64: optimize register allocation orderaurel32
The beginning of the register allocation order list on the TCG x86_64 target matches the list of clobbered registers. This means that when an helper is called, there is almost always clobbered registers that have to be spilled. The same way register %rsi and %rdi are at the top of the register allocation order list, while they can't be used for load/store operations. This means the data and/or address registers are very often %rsi and %rdi, and their values have to be spilled, and then moved back to another register. This patches changes to the allocation order to avoid those effects. It results in a 8% gain speed in qemu-x86_64 to compress a bzip2 file, and a 6% gain in qemu-system-mips64 to compile a small application.
