2021-02-11m68k: MOVEC insn. should generate exception if wrong CR is accessedLucien Murray-Pitts
Add CPU class detection for each CR type in the m68k_move_to/from helpers, so that it throws and exception if an unsupported register is requested for that CPU class. Reclassified MOVEC insn. as only supported from 68010.

2021-02-11m68k: add missing BUSCR/PCR CR defines, and BUSCR/PCR/CAAR CR to ↵Lucien Murray-Pitts
m68k_move_to/from The BUSCR/PCR CR defines were missing for 68060, and the move_to/from helper functions were also missing a decode for the 68060 M68K_CR_CAAR CR register. Added missing defines, and respective decodes for all three CR registers to the helpers. Although this patch defines them, the implementation is empty in this patch and these registers will result in a cpu abort - which is the default prior to this patch. This patch aims to reach full coverage of all CR registers within the helpers.

2021-02-11m68k: cascade m68k_features by m680xx_cpu_initfn() to improve readabilityLucien Murray-Pitts
The m680XX_cpu_initfn functions have been rearranged to cascade starting from the base 68000, so that the 68010 then inherits from this, and so on until the 68060. This makes it simpler to track features since in most cases the m68k were product enhancements on each other, with only a few instructions being retired. Because each cpu class inherits the previous CPU class, then for example the 68020 also has the feature 68010, and 68000 and so on upto the 68060. - Added 68010 cpu class, and moved correct features into 68000/68010. - Added m68k_unset_feature to allow removing a feature in the inheritence Signed-off-by: Lucien Murray-Pitts <lucienmp.qemu@gmail.com> Reviewed-by: Laurent Vivier <laurent@vivier.eu> Signed-off-by: BALATON Zoltan <balaton@eik.bme.hu> Message-Id: <c652fe7537f8b4fe87a13ecbbc0ea751fb71532f.1612137712.git.balaton@eik.bme.hu> Signed-off-by: Laurent Vivier <laurent@vivier.eu>

2021-02-05cpu: tcg_ops: move to tcg-cpu-ops.h, keep a pointer in CPUClassClaudio Fontana
we cannot in principle make the TCG Operations field definitions conditional on CONFIG_TCG in code that is included by both common_ss and specific_ss modules. Therefore, what we can do safely to restrict the TCG fields to TCG-only builds, is to move all tcg cpu operations into a separate header file, which is only included by TCG, target-specific code. This leaves just a NULL pointer in the cpu.h for the non-TCG builds. This also tidies up the code in all targets a bit, having all TCG cpu operations neatly contained by a dedicated data struct.

2021-02-05target/arm: do not use cc->do_interrupt for KVM directlyClaudio Fontana
cc->do_interrupt is in theory a TCG callback used in accel/tcg only, to prepare the emulated architecture to take an interrupt as defined in the hardware specifications, but in reality the _do_interrupt style of functions in targets are also occasionally reused by KVM to prepare the architecture state in a similar way where userspace code has identified that it needs to deliver an exception to the guest. In the case of ARM, that includes: 1) the vcpu thread got a SIGBUS indicating a memory error, and we need to deliver a Synchronous External Abort to the guest to let it know about the error. 2) the kernel told us about a debug exception (breakpoint, watchpoint) but it is not for one of QEMU's own gdbstub breakpoints/watchpoints so it must be a breakpoint the guest itself has set up, therefore we need to deliver it to the guest. So in order to reuse code, the same arm_do_interrupt function is used. This is all fine, but we need to avoid calling it using the callback registered in CPUClass, since that one is now TCG-only. Fortunately this is easily solved by replacing calls to CPUClass::do_interrupt() with explicit calls to arm_do_interrupt().

2021-02-05tcg/tci: Make tci_tb_ptr thread-localRichard Henderson
Each thread must have its own pc, even under TCI. Remove the GETPC ifdef, because GETPC is always available for helpers, and thus is always required. Move the assignment under INDEX_op_call, because the value is only visible when we make a call to a helper function.

The configure option was backward, and we failed to pass the value on to meson.

2021-02-05tcg/aarch64: Do not convert TCGArg to temps that are not tempsRichard Henderson
Fixes INDEX_op_rotli_vec for aarch64 host, where the 3rd argument is an integer, not a temporary, which now tickles an assert added in e89b28a6350. Previously, the value computed into v2 would be garbage for rotli_vec, but as the value was unused it caused no harm. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
