2010-03-29tcg/mips: fix branch offset during retranslationAurelien Jarno
Branch offsets should only be overwritten during relocation, to support partial retranslation. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

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: Use TCGCond where appropriate.Richard Henderson
Use the TCGCond enumeration type in the brcond and setcond related prototypes in tcg-op.h and each code generator. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-03-26tcg: Name the opcode enumeration.Richard Henderson
Give the enumeration formed from tcg-opc.h a name: TCGOpcode. Use that enumeration type instead of "int" whereever appropriate. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-02-09tcg/mips: fix crash in tcg_out_qemu_ld()Aurelien Jarno
The address register is overriden when it corresponds to v0 and the fast path is taken, which leads to a crash. Fix that by using the a0 register instead. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2009-12-01tcg: initial mips supportAurelien Jarno
Based on a patch from Arnaud Patard (Rtp) <arnaud.patard@rtp-net.org> A few words about design choices: * Two registers, at and t0, are reserved for TCG internal use. They are useful for bswap and 64-bit ops. * Most ops supports a constant argument with value 0, which is actually mapped to the zero register. * While the at register is available for constant loading, ops only support a limited range of constants. TCG does a better job doing the register allocation and constant loading by itself. There are plenty of registers available anyway. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
