2018-01-16mips: Tweak location of ';' in macrosEric Blake
It is more typical to provide the ';' by the caller of a macro than to embed it in the macro itself; this is because syntax highlight engines can get confused if a macro is called without a semicolon before the closing '}'.

2018-01-12i386/cpu/kvm: look at PMU's CPUID before setting MSRsJan Dakinevich
Certain PMU-related MSRs are not supported for CPUs with PMU architecture below version 2. KVM rejects any access to them (see intel_is_valid_msr_idx routine in KVM), and QEMU fails on the following assertion: kvm_put_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed. QEMU also could fail if KVM exposes less fixed counters then 3. It could happen if host system run inside another hypervisor, which is tweaking PMU-related CPUID. To prevent possible fail, number of fixed counters now is obtained in the same way as number of GP counters.

Refactor disas_thumb2_insn() so that it generates the code for raising an UNDEF exception for invalid insns, rather than returning a flag which the caller must check to see if it needs to generate the UNDEF code. This brings the function in to line with the behaviour of disas_thumb_insn() and disas_arm_insn().

2018-01-11target/arm: Fix stlxp for aarch64_beMichael Weiser
ldxp loads two consecutive doublewords from memory regardless of CPU endianness. On store, stlxp currently assumes to work with a 128bit value and consequently switches order in big-endian mode. With this change it packs the doublewords in reverse order in anticipation of the 128bit big-endian store operation interposing them so they end up in memory in the right order. This makes it work for both MTTCG and !MTTCG. It effectively implements the ARM ARM STLXP operation pseudo-code: data = if BigEndian() then el1:el2 else el2:el1; With this change an aarch64_be Linux 4.14.4 kernel succeeds to boot up in system emulation mode.

Add two debug-mode-only opcodes: - rfdd and rfdo do return from the debug mode, which is not emulated. Add three internal opcodes for full MMU: - hwwdtlba and hwwitlba are the internal opcodes that write a value into autoupdate DTLB or ITLB entry. - ldpte is internal opcode that loads PTE entry that covers the most recent page fault address.

2018-01-04target/m68k: fix gen_get_ccr()Laurent Vivier
As gen_helper_get_ccr() is able to compute CCR from cc_op and flags, we don't need to flush flags before to call it. flush_flags() and get_ccr() use COMPUTE_CCR() to compute flags. get_ccr() computes CCR value, whereas flush_flags update live cc_op and flags.

2017-12-29tcg: Dynamically allocate TCGOpsRichard Henderson
With no fixed array allocation, we can't overflow a buffer. This will be important as optimizations related to host vectors may expand the number of ops used. Use QTAILQ to link the ops together. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2017-12-27target/*helper: don't check retaddr before calling cpu_restore_stateAlex Bennée
cpu_restore_state officially supports being passed an address it can't resolve the state for. As a result the checks in the helpers are superfluous and can be removed. This makes the code consistent with other users of cpu_restore_state. Of course this does nothing to address what to do if cpu_restore_state can't resolve the state but so far it seems this is handled elsewhere. The change was made with included coccinelle script. Signed-off-by: Alex Bennée <alex.bennee@linaro.org> [rth: Fixed up comment indentation. Added second hunk to script to combine cpu_restore_state and cpu_loop_exit.] Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
