2012-10-10hw: Added generic FIFO API.Peter A. G. Crosthwaite
Added a FIFO API that can be used to create and operate byte FIFOs. Signed-off-by: Peter A. G. Crosthwaite <peter.crosthwaite@petalogix.com>
2012-10-10stellaris: Removed SSI muxPeter A. G. Crosthwaite
Removed the explicit SSI mux and wired the CS line directly up to the SSI devices. Signed-off-by: Peter A. G. Crosthwaite <peter.crosthwaite@petalogix.com>
2012-10-10qdev: allow multiple qdev_init_gpio_in() callsPeter A. G. Crosthwaite
Allow multiple qdev_init_gpio_in() calls for the one device. The first call will define GPIOs 0-N-1, the next GPIOs N- ... . Allows different GPIOs to be handled with different handlers. Needed when two levels of the QOM class heirachy both define GPIO functionality, as a single GPIO handler with an index selecter is not possible. Signed-off-by: Peter A. G. Crosthwaite <peter.crosthwaite@petalogix.com> Reviewed-by: Peter Maydell <peter.maydell@linaro.org>
2012-10-10ssi: Added create_slave_no_init()Peter A. G. Crosthwaite
Slave creation function that can be used to create an SSI slave without qdev_init() being called. This give machine models a chance to set properties. Signed-off-by: Peter A. G. Crosthwaite <peter.crosthwaite@petalogix.com> Acked-by: Peter Maydell <peter.maydell@linaro.org>
2012-10-10ssi: Implemented CS behaviourPeter A. G. Crosthwaite
Added default CS behaviour for SSI slaves. SSI devices can set a property to enable CS behaviour which will create a GPIO on the device which is the CS. Tristating of the bus on SSI transfers is implemented. Signed-off-by: Peter A. G. Crosthwaite <peter.crosthwaite@petalogix.com> Acked-by: Peter Maydell <peter.maydell@linaro.org>
2012-10-10ssi: Support for multiple attached devicesPeter A. G. Crosthwaite
Removed assertion that only one device is attached to the SSI bus. When multiple devices are attached, all slaves have their transfer function called for transfers. Each device is responsible for knowing whether or not its CS is active, and if not returning 0. The returned data is the logical or of all responses from the (mulitple) devices.

2012-10-07qemu-barrier: Fix compilation on i386 hostsAurelien Jarno
Commit 1d31fca470648ec66afd8743491bfb5846306341 tried to fix bug introduced by 610b823ef66b993660f1ab1447a769f190e4f3b3 by including qemu-common.h, which breaks the build further. Include compiler.h instead, as suggested by Blue Swirl. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2012-10-07target-sparc: Optimize conditionals using SUBCCRichard Henderson
Aka "normal" comparisons. We now have the infrastructure to pass back non-boolean results from gen_compare. This will automatically get used by both branches and conditional moves. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-07target-sparc: Fall through from not-taken trapRichard Henderson
Now that we've cleaned up global temporary allocation, we can continue translating the fallthru path of a conditional trap. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-07target-sparc: Cleanup "global" temporary allocationRichard Henderson
There are 6 temporaries that disas_sparc_insn relies on having been allocated. Now that they are no longer referenced across branches, they need not be allocated as local temps. Move the allocation/free of these temporaries to make it clear that they are local to the translation of a single insn.

2012-10-07target-sparc: Move taddcctv and tsubcctv out of lineRichard Henderson
The branches around the exception are maintaining an otherwise unnecessary use of local temps for the cpu destination. Note that gen_op_t{add,sub}_cc were identical to gen_op_{add,sub}_cc. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-07target-sparc: Tidy TccRichard Henderson
Share more code between unconditional and conditional paths. Move the computation of the trap number into the conditional BB; avoid using temporaries that have gone out of scope (cpu_tmp32) or rely on local temps (cpu_dst). Fully fold the exception number when the trap number is %g0+imm. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-10-07target-sparc: Make CPU_LOG_INT useful by defaultRichard Henderson
No need for ifdefs when the log mask does just as well. No need to print pc/npc when we're dumping the whole cpu state. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-10-07target-sparc: Tidy cpu_dump_stateRichard Henderson

2012-10-07tcg: Remove redundant pointer from TCGContextStefan Weil
The pointer entry 'temps' always refers to the array entry 'static_temps'. Removing the pointer and renaming 'static_temps' to 'temps' reduces the size of TCGContext (4 or 8 byte) and allows better code generation.

2012-10-06qemu-barrier: Fix compilation on i386 hostsStefan Weil
Commit 610b823ef66b993660f1ab1447a769f190e4f3b3 uses QEMU_GNUC_PREREQ on i386 hosts. That macro is defined in qemu-common.h which is not always included before qemu-barrier.h, so compilation on i386 hosts was broken.
