* tcg: Don't declare TCG_TARGET_REG_BITS in tcg-target.hStefan Weil2011-10-011-1/+0
| | | | | | | | It is now declared for all tcg targets in tcg.h, so the tcg target specific declarations are redundant. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
* tcg/ppc/tcg-target.c: Avoid 'set but not used' gcc warningsPeter Maydell2011-09-011-10/+10
| | | | | | | | | Move the declaration and initialisation of some variables in tcg_out_qemu_ld and tcg_out_qemu_st inside CONFIG_SOFTMMU, to avoid the "variable set but not used" warning of gcc 4.6. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: malc <av1474@comtv.ru>

* tcg: Always define all of the TCGOpcode enum members.Richard Henderson2011-08-211-15/+16
| | | | | | | | | | | | 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>

* Delegate setup of TCG temporaries to targetsBlue Swirl2011-06-261-0/+2
| | | | | | | Delegate TCG temp_buf setup to targets, so that they can use a stack frame later instead. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
* cpu-exec.c: avoid AREG0 useBlue Swirl2011-06-261-3/+3
| | | | | | | | | | | | | | | | | 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. Compile the file without HELPER_CFLAGS. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
* TCG: Fix Darwin/ppc calling convention recognitionAndreas Färber2010-08-151-1/+1
| | | | | | | | | | | | 5da79c86a3744e3a901c7986c109dd06951befd2 broke compilation on Mac OS X v10.5 ppc. Apple's GCC 4.0.1 does not define _CALL_DARWIN. Recognize __APPLE__ again as well.

* tcg: Add TYPE parameter to tcg_out_mov.Richard Henderson2010-06-091-24/+24
| | | | | | | | | | | | | | 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>

* Split TLB addend and target_phys_addr_tPaul Brook2010-04-051-10/+2
| | | | | | | | | | | | | | 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.

* tcg: Disambiguate qemu_ld32u with 32-bit and 64-bit outputs.Richard Henderson2010-03-261-3/+3
| | | | | | | | | | | | | | | 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.
