2012-03-18softmmu templates: optionally pass CPUState to memory access functionsBlue Swirl1-3/+47
Optionally, make memory access helpers take a parameter for CPUState instead of relying on global env. On most targets, perform simple moves to reorder registers. On i386, switch from regparm(3) calling convention to standard stack-based version. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-03-11tcg: Improve tcg_out_label and fix its usage for w64Stefan Weil1-3/+3
tcg_out_label is always called with a third argument of pointer type which was casted to tcg_target_long. These casts can be avoided by changing the prototype of tcg_out_label. There was also a cast to long. For most hosts with sizeof(long) == sizeof(tcg_target_long) == sizeof(void *) this did not matter, but for w64 it was wrong. This is fixed now.

2012-03-03w64: Change data type of parameters for flush_icache_rangeStefan Weil1-1/+2
The TCG targets i386 and tci needed a change of the function prototype for w64. This change is currently not needed for the other TCG targets, but it can be applied to avoid code differences.

2011-11-19tcg-sparc: Fix set-but-not used warnings.Richard Henderson1-4/+0
In both cases, val is computed, but then not used in the subsequent line, which then re-computes the quantity in a different type (int32_t vs unsigned long).

2011-08-21tcg: Always define all of the TCGOpcode enum members.Richard Henderson1-33/+35
By always defining these symbols, we can eliminate a lot of ifdefs. To allow this to be checked reliably, the semantics of the TCG_TARGET_HAS_* macros must be changed from def/undef to true/false. This allows even more ifdefs to be removed, converting them into C if statements. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-06-26TCG/Sparc64: use stack for TCG tempsBlue Swirl1-3/+4
Use stack instead of temp_buf array in CPUState for TCG temps. On Sparc64, stack pointer is not aligned but there is a fixed bias of 2047, so don't try to enforce alignment. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-06-26cpu-exec.c: avoid AREG0 useBlue Swirl1-2/+2
Make functions take a parameter for CPUState instead of relying on global env. Pass CPUState pointer to TCG prologue, which moves it to AREG0. Thanks to Peter Maydell and Laurent Desnogues for the ARM prologue change. Revert the hacks to avoid AREG0 use on Sparc hosts. Move cpu_has_work() and cpu_pc_from_tb() from exec.h to cpu.h.

2010-06-16tcg: Optionally sign-extend 32-bit arguments for 64-bit hosts.Richard Henderson1-0/+4
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 Henderson1-5/+5
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 Brook1-7/+1
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 Henderson1-1/+5
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.

2010-01-12tcg-sparc: Implement division properly.Richard Henderson2-30/+55
The {div,divu}2 opcodes are intended for systems for which the division instruction produces both quotient and remainder. Sparc is not such a system. Indeed, the remainder must be computed as quot = a / b rem = a - (quot * b) Split out a tcg_out_div32 function that properly initializes Y with the extension of the input to 64-bits. Discard the code that used the 64-bit DIVX on sparc9/sparcv8plus without extending the inputs to 64-bits. Implement remainders in terms of division followed by multiplication.
