Peter Collingbourne 2d928adf8a target/arm: Use TCF0 and TFSRE0 for unprivileged tag checks
Section D6.7 of the ARM ARM states:

For the purpose of determining Tag Check Fault handling, unprivileged
load and store instructions are treated as if executed at EL0 when
executed at either:
- EL1, when the Effective value of PSTATE.UAO is 0.
- EL2, when both the Effective value of HCR_EL2.{E2H, TGE} is {1, 1}
  and the Effective value of PSTATE.UAO is 0.

ARM has confirmed a defect in the pseudocode function
AArch64.TagCheckFault that makes it inconsistent with the above
wording. The remedy is to adjust references to PSTATE.EL in that
function to instead refer to AArch64.AccessUsesEL(acctype), so
that unprivileged instructions use SCTLR_EL1.TCF0 and TFSRE0_EL1.
The exception type for synchronous tag check faults remains unchanged.

This patch implements the described change by partially reverting
commits 50244cc76a and cc97b0019b.

Richard Henderson 519183d3fe target/arm: Speed up aarch64 TBL/TBX
Always perform one call instead of two for 16-byte operands.
Use byte loads/stores directly into the vector register file
instead of extractions and deposits to a 64-bit local variable.

In order to easily receive pointers into the vector register file,
convert the helper to the gvec out-of-line signature.  Move the
helper into vec_helper.c, where it can make use of H1 and clear_tail.

Thomas Huth ea1b90b4fc target/s390x/arch_dump: Fix warning for the name field in the PT_NOTE section
There is a compiler warning with GCC 9.3 when compiling with
the -fsanitize=thread compiler flag:

 In function 'strncpy',
    inlined from 's390x_write_elf64_notes' at ../target/s390x/arch_dump.c:219:9:
 /usr/include/x86_64-linux-gnu/bits/string_fortified.h:106:10: error:
  '__builtin_strncpy' specified bound 8 equals destination size
  [-Werror=stringop-truncation]

Since the name should always be NUL-terminated, let's use g_strlcpy() to
silence this warning. And while we're at it, also add an assert() to make
sure that the provided names always fit the size field (which is fine for
the current callers, the function is called once with "CORE" and once with
"LINUX" as a name).

Secure execution (aka protected virtualization) guests cannot be
migrated at the moment. If the unpack facility is provided in the cpu
model, a guest may choose to transition to secure mode, making the
guest unmigratable at that point in time. If the machine was explicitly
started with --only-migratable, we would get a failure only when the
guest actually tries to transition; instead, explicitly disallow the
unpack facility if --only-migratable was specified to avoid late
surprises.

Philippe Mathieu-Daudé cefd68f6b1 target/mips: Promote 128-bit multimedia registers as global ones
The cpu::mmr[] array contains the upper halves of 128-bit GPR
registers. While they are only used by the R5900 CPU, the
concept is generic and could be used by another MIPS implementation.

Rename 'cpu::mmr' as 'cpu::gpr_hi' and make them global.

When the code is similar to the GPR lower halves, move it
close by.

Commit 83be6b5412 ("Fix MSA instructions LD.<B|H|W|D> on big endian

without including it. This was not a problem because "tcg/tcg.h" is
pulled in by "exec/cpu_ldst.h". To be able to remove this header
there, we first need to include it here in op_helper.c, else we get:

Taylor Simpson 3e7a84eecc Hexagon build infrastructure
Add file to default-configs
Add hexagon to meson.build
Add hexagon to target/meson.build
Add target/hexagon/meson.build
Change scripts/qemu-binfmt-conf.sh

We can build a hexagon-linux-user target and run programs on
the Hexagon scalar core.  With hexagon-linux-clang installed,
"make check-tcg" will pass.

Helpers won't work if there are multiple definitions, so we override these
instructions using #define fGEN_TCG_<tag>.
