2011-04-12target-arm: Detect tininess before rounding for FP operationsPeter Maydell1-0/+4
The ARM architecture mandates that we detect tininess before rounding, so set the softfloat fp_status up appropriately. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-04-12target-arm: Treat UNPREDICTABLE VTBL, VTBX case as UNDEFPeter Maydell1-1/+8

2011-04-12target-arm: Handle UNDEF cases for Neon 2 register misc formsPeter Maydell1-5/+16
Add missing UNDEF checks for Neon "two register miscellaneous" forms: * all instructions except VMOVN,VQMOVN must UNDEF if Q==1 && (Vd<0> == 1 || Vm<0> == 1) * VMOVN,VQMOVN,VCVT.F16.F32 UNDEF if Q == 1 || Vm<0> == 1 * VSHLL,VCVT.F32.F16 UNDEF if Q == 1 || Vd<0> == 1 (The only other UNDEF case is VZIP,VUZP if Q == 0 && size == 10, which we already handle.)

2011-04-12target-arm: Simplify checking of size field in Neon 2reg-misc formsPeter Maydell1-76/+179
Many of the Neon "2 register misc" instruction forms require invalid size fields to cause the instruction to UNDEF. Pull this information out into an array; this simplifies the code and also means we can do the check early and avoid the problem of leaking TCG temporaries in the illegal_op case.

For Neon "one register and a modified immediate value" forms, the combination op=1 cmode=1111 is unallocated and should UNDEF. All instructions of this form also UNDEF if Q == 1 and Vd<0> == 1.

2011-04-12target-arm: Collapse VSRI case into VSHL, VSLIPeter Maydell1-4/+0
Collapse some switch cases for VSRI into those for VSHL, VSLI, since the bodies are the same. (This is not completely obvious for the size < 3 case, but since for VSRI we know U=1 the GEN_NEON_INTEGER_OP() expansion is equivalent to the open-coded VSHL/VSLI case.)

2011-04-12Replace cpu_physical_memory_rw were possibleStefan Weil8-21/+19
Using cpu_physical_memory_read, cpu_physical_memory_write and ldub_phys improves readability and allows removing some type casts. lduw_phys and ldl_phys were not used because both require aligned addresses. Therefore it is not possible to simply replace existing calls by one of these functions. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-04-12cpu-common: Modify cpu_physical_memory_read and cpu_physical_memory_writeStefan Weil1-3/+3
A lot of calls don't operate on bytes but on words or on structured data. So instead of a pointer to uint8_t, a void pointer is the better choice. This allows removing many type casts. (Some very early implementations of memcpy used char pointers which were replaced by void pointers for the same reason).

2011-04-10arm: basic support for ARMv4/ARMv4T emulationDmitry Eremin-Solenikov3-12/+80
Currently target-arm/ assumes at least ARMv5 core. Add support for handling also ARMv4/ARMv4T. This changes the following instructions: BX(v4T and later) BKPT, BLX, CDP2, CLZ, LDC2, LDRD, MCRR, MCRR2, MRRC, MCRR, MRC2, MRRC, MRRC2, PLD QADD, QDADD, QDSUB, QSUB, STRD, SMLAxy, SMLALxy, SMLAWxy, SMULxy, SMULWxy, STC2 (v5 and later) All instructions that are "v5TE and later" are also bound to just v5, as that's how it was before. This patch doesn _not_ include disabling of cp15 access and base-updated data abort model (that will be required to emulate chips based on a ARM7TDMI), because: * no ARM7TDMI chips are currently emulated (or planned) * those features aren't strictly necessary for my purposes (SA-1 core emulation). All v5 models are handled as they are v5T. Internally we still have a check if the model is a v5(T) or v5TE, but as all emulated cores are v5TE, those two cases are simply aliased (for now). Patch is heavily based on patch by Filip Navara <filip.navara@gmail.com> which in turn is based on work by Ulrich Hecht <uli@suse.de> and Vincent Sanders <vince@kyllikki.org>.

2011-04-10vnc: tight: Fix crash after 2GB of outputMichael Tokarev2-4/+5
fix 2Gb integer overflow in in VNC tight and zlib encodings As found by Roland Dreier <roland@purestorage.com> (excellent catch!), when amount of VNC compressed data produced by zlib and sent to client exceeds 2Gb, integer overflow occurs because currently, we calculate amount of data produced at each step by comparing saved total_out with new total_out, and total_out is something which grows without bounds. Compare it with previous avail_out instead of total_out, and leave total_out alone. The same code is used in vnc-enc-tight.c and vnc-enc-zlib.c, so fix both cases. There, there's no actual need to save previous_out value, since capacity-offset (which is how that value is calculated) stays the same so it can be recalculated again after call to deflate(), but whole thing becomes less readable this way.
