2019-02-01arm: Clarify the logic of set_pc()Julia Suvorova
Until now, the set_pc logic was unclear, which raised questions about whether it should be used directly, applying a value to PC or adding additional checks, for example, set the Thumb bit in Arm cpu. Let's set the set_pc logic for “Configure the PC, as was done in the ELF file” and implement synchronize_with_tb hook for preserving PC to cpu_tb_exec.

2019-02-01target/arm/translate-a64: Fix mishandling of size in FCMLA decodePeter Maydell
In disas_simd_indexed(), for the case of "complex fp", each indexable element is a complex pair, so the total size is twice that indicated in the 'size' field in the encoding. We were trying to do this "double the size" operation with a left shift by 1, but this is incorrect because the 'size' field is a MO_8/MO_16/MO_32/MO_64 value, and doubling the size should be done by a simple increment. This meant we were mishandling FCMLA (by element) of values where the real and imaginary parts are 32-bit floats, and would incorrectly UNDEF this encoding. (No other insns take this code path, and for 16-bit floats it happens that 1 << 1 and 1 + 1 are both the same).

2019-01-29target/arm: Don't clear supported PMU events when initializing PMCEID1Aaron Lindsay OS
A bug was introduced during a respin of: commit 57a4a11b2b281bb548b419ca81bfafb214e4c77a target/arm: Add array for supported PMU events, generate PMCEID[01]_EL0 This patch introduced two calls to get_pmceid() during CPU initialization - one each for PMCEID0 and PMCEID1. In addition to building the register values, get_pmceid() clears an internal array mapping event numbers to their implementations (supported_event_map) before rebuilding it. This is an optimization since much of the logic is shared. However, since it was called twice, the contents of supported_event_map reflect only the events in PMCEID1 (the second call to get_pmceid()). Fix this bug by moving the initialization of PMCEID0 and PMCEID1 back into a single function call, and name it more appropriately since it is doing more than simply generating the contents of the PMCEID[01] registers.

2019-01-29target/arm: v8m: Ensure IDAU is respected if SAU is disabledThomas Roth
The current behavior of v8m_security_lookup in helper.c only checks whether the IDAU specifies a higher security if the SAU is enabled. If SAU.ALLNS is set to 1, this will lead to addresses being treated as non-secure, even though the IDAU indicates that they must be secure. This patch changes the behavior to also check the IDAU if the SAU is currently disabled. (This brings the behaviour here into line with the v8M Arm ARM SecurityCheck() pseudocode.)

2019-01-22target/microblaze: Switch to transaction_failed hookPeter Maydell
Switch the microblaze target from the old unassigned_access hook to the transaction_failed hook. The notable difference is that rather than it being called for all physical memory accesses which fail (including those made by DMA devices or by the gdbstub), it is only called for those made by the CPU via its MMU. For microblaze this makes no difference because none of the target CPU code needs to make loads or stores by physical address.

When compiling the ppc code with clang and -std=gnu99, there are a couple of warnings/errors like this one: CC ppc64-softmmu/hw/intc/xics.o In file included from hw/intc/xics.c:35: include/hw/ppc/xics.h:43:25: error: redefinition of typedef 'ICPState' is a C11 feature [-Werror,-Wtypedef-redefinition] typedef struct ICPState ICPState; ^ target/ppc/cpu.h:1181:25: note: previous definition is here typedef struct ICPState ICPState; ^ Work around the problems by including the proper headers in spapr.h and by using struct forward declarations in cpu.h.

2019-01-21target/arm: PMU: Add instruction and cycle eventsAaron Lindsay
The instruction event is only enabled when icount is used, cycles are always supported. Always defining get_cycle_count (but altering its behavior depending on CONFIG_USER_ONLY) allows us to remove some CONFIG_USER_ONLY #defines throughout the rest of the code.

2019-01-21target/arm: Add array for supported PMU events, generate PMCEID[01]_EL0Aaron Lindsay
This commit doesn't add any supported events, but provides the framework for adding them. We store the pm_event structs in a simple array, and provide the mapping from the event numbers to array indexes in the supported_event_map array. Because the value of PMCEID[01] depends upon which events are supported at runtime, generate it dynamically.
