2010-08-15TCG: Revert ppc64 tcg_out_movi32 changeAndreas Färber
3b6dac34161bc0a342336072643c2f6d17e0ec45 apparently broke the ppc64 TCG target compilation in the code path without guest base. Reverting this line fixes the build.

2010-06-16tcg: Optionally sign-extend 32-bit arguments for 64-bit hosts.Richard Henderson
Some hosts (amd64, ia64) have an ABI that ignores the high bits of the 64-bit register when passing 32-bit arguments. Others require the value to be properly sign-extended for the type. I.e. "int32_t" must be sign-extended and "uint32_t" must be zero-extended to 64-bits. To effect this, extend the "sizemask" parameter to tcg_gen_callN to include the signedness of the type of each parameter. If the tcg target requires it, extend each 32-bit argument into a 64-bit temp and pass that to the function call. This ABI feature is required by sparc64, ppc64 and s390x.

2010-06-09tcg: Add TYPE parameter to tcg_out_mov.Richard Henderson
Mirror tcg_out_movi in having a TYPE parameter. This allows x86_64 to perform the move at the proper width, which may elide a REX prefix. Introduce a TCG_TYPE_REG enumerator to represent the "native width" of the host register, and to distinguish the usage from "pointer data" as represented by the existing TCG_TYPE_PTR. Update all targets to match. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-04-05Split TLB addend and target_phys_addr_tPaul Brook
Historically the qemu tlb "addend" field was used for both RAM and IO accesses, so needed to be able to hold both host addresses (unsigned long) and guest physical addresses (target_phys_addr_t). However since the introduction of the iotlb field it has only been used for RAM accesses. This means we can change the type of addend to unsigned long, and remove associated hacks in the big-endian TCG backends. We can also remove the host dependence from target_phys_addr_t.

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.
