2010-03-26tcg: Disambiguate qemu_ld32u with 32-bit and 64-bit outputs.Richard Henderson
Some targets (e.g. Alpha and MIPS64) need to keep 32-bit operands sign-extended in 64-bit registers (regardless of the "real" sign of the operand). For that, we need to be able to distinguish between a 32-bit load with a 32-bit result and a 32-bit load with a given extension to a 64-bit result. This distinction already exists for the ld* loads, but not the qemu_ld* loads. Reserve qemu_ld32u for 64-bit outputs and introduce qemu_ld32 for 32-bit outputs. Adjust all code generators to match.

2010-03-26tcg: Change TCGType to an enumeration.Richard Henderson
The TCGType name was already used consistently. Changing it to an enumeration instead of a set of defines aids debugging. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-03-26tcg: Use TCGCond where appropriate.Richard Henderson

2010-03-14tcg: declare internal helpers as const and pureAurelien Jarno
TCG internal helpers only access to the values passed in arguments, and do not modify the CPU internal state. Thus they can be declared as const and pure. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-03-14tcg: add div/rem 32-bit helpersAurelien Jarno
Some targets like ARM would benefit to use 32-bit helpers for div/rem/divu/remu. Create a #define for div2 so that targets can select between div, div2 and helper implementation. Use the helper version if none of the #define are present. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

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.

This patch removes useless type information in some calls to tcg_temp_local_new.
