2017-10-16linux-user: fix O_TMPFILE handlingRiku Voipio3-1/+14
Since O_TMPFILE might differ between guest and host, add it to the bitmask_transtbl. While at it, fix the definitions of O_DIRECTORY etc which should arm32 according to kernel sources. This fixes open14 and openat03 ltp testcases. Fixes: https://bugs.launchpad.net/qemu/+bug/1709170

2017-10-12nvic: Fix miscalculation of offsets into ITNS arrayPeter Maydell1-2/+2
This calculation of the first exception vector in the ITNS<n> register being accessed: int startvec = 32 * (offset - 0x380) + NVIC_FIRST_IRQ; is incorrect, because offset is in bytes, so we only want to multiply by 8. Spotted by Coverity (CID 1381484, CID 1381488), though it is not correct that it actually overflows the buffer, because we have a 'startvec + i < s->num_irq' guard.

2017-10-12target/arm: Implement SG instruction corner casesPeter Maydell1-1/+22
The common situation of the SG instruction is that it is executed from S&NSC memory by a CPU in NS state. That case is handled by v7m_handle_execute_nsc(). However the instruction also has defined behaviour in a couple of other cases: * SG instruction in NS memory (behaves as a NOP) * SG in S memory but CPU already secure (clears IT bits and does nothing else) * SG instruction in v8M without Security Extension (NOP) These can be implemented in translate.c.

2017-10-12target/arm: Support some Thumb insns being always unconditionalPeter Maydell1-1/+47
A few Thumb instructions are always unconditional even inside an IT block (as opposed to being UNPREDICTABLE if used inside an IT block): BKPT, the v8M SG instruction, and the A profile HLT (debug halt) instruction. This means we need to suppress the jump-over-instruction-on-condfail code generation (though the IT state still advances as usual and subsequent insns in the IT block may be conditional).

2017-10-12target-arm: Simplify insn_crosses_page()Peter Maydell1-21/+6
Recent changes have left insn_crosses_page() more complicated than it needed to be: * it's only called from thumb_tr_translate_insn() so we know for certain that we're looking at a Thumb insn * the caller's check for dc->pc >= dc->next_page_start - 3 means that dc->pc can't possibly be 4 aligned, so there's no need to check that (the check was partly there to ensure that we didn't treat an ARM insn as Thumb, I think) * we now have thumb_insn_is_16bit() which lets us do a precise check of the length of the next insn, rather than opencoding an inaccurate check Simplify it down to just loading the first half of the insn and calling thumb_insn_is_16bit() on it.

2017-10-12target/arm: Pull Thumb insn word loads up to top levelPeter Maydell1-70/+108
Refactor the Thumb decode to do the loads of the instruction words at the top level rather than only loading the second half of a 32-bit Thumb insn in the middle of the decode. This is simple apart from the awkward case of Thumb1, where the BL/BLX prefix and suffix instructions live in what in Thumb2 is the 32-bit insn space. To handle these we decode enough to identify whether we're looking at a prefix/suffix that we handle as a 16 bit insn, or a prefix that we're going to merge with the following suffix to consider as a 32 bit insn. The translation of the 16 bit cases then moves from disas_thumb2_insn() to disas_thumb_insn(). The refactoring has the benefit that we don't need to pass the CPUARMState* down into the decoder code any more, but the major reason for doing this is that some Thumb instructions must be always unconditional regardless of the IT state bits, so we need to know the whole insn before we emit the "skip this insn if the IT bits and cond state tell us to" code. (The always unconditional insns are BKPT, HLT and SG; the last of these is 32 bits.)

2017-10-12target-arm: Don't check for "Thumb2 or M profile" for not-Thumb1Peter Maydell1-2/+1
The code which implements the Thumb1 split BL/BLX instructions is guarded by a check on "not M or THUMB2". All we really need to check here is "not THUMB2" (and we assume that elsewhere too, eg in the ARCH(6T2) test that UNDEFs the Thumb2 insns). This doesn't change behaviour because all M profile cores have Thumb2 and so ARM_FEATURE_M implies ARM_FEATURE_THUMB2. (v6M implements a very restricted subset of Thumb2, but we can cross that bridge when we get to it with appropriate feature bits.)

2017-10-12target/arm: Implement secure function returnPeter Maydell3-10/+126
Secure function return happens when a non-secure function has been called using BLXNS and so has a particular magic LR value (either 0xfefffffe or 0xfeffffff). The function return via BX behaves specially when the new PC value is this magic value, in the same way that exception returns are handled. Adjust our BX excret guards so that they recognize the function return magic number as well, and perform the function-return unstacking in do_v7m_exception_exit().

Use logging module for the QMP debug messages. The only scripts that set debug=True are iotests.py and guestperf/engine.py, and they already call logging.basicConfig() to set up logging. Scripts that don't configure logging are safe as long as they don't need debugging output, because debug messages don't trigger the "No handlers could be found for logger" message from the Python logging module. Scripts that already configure logging but don't use debug=True (e.g. scripts/vm/basevm.py) will get QMP debugging enabled for free.
