cf5ec6641e target/i386: implement F16C instructions
F16C only consists of two instructions, which are a bit peculiar
nevertheless.

First, they access only the low half of an YMM or XMM register for the
packed-half operand; the exact size still depends on the VEX.L flag.
This is similar to the existing avx_movx flag, but not exactly because
avx_movx is hardcoded to affect operand 2.  To this end I added a "ph"
format name; it's possible to reuse this approach for the VPMOVSX and
VPMOVZX instructions, though that would also require adding two more
formats for the low-quarter and low-eighth of an operand.

Second, VCVTPS2PH is somewhat weird because it *stores* the result of
the instruction into memory rather than loading it.

15b273f8e6 tests/tcg: move compiler tests to Makefiles
Further decoupling of tests/tcg from the main QEMU Makefile, and making

c6cf8a2052 tests/tcg: clean up calls to run-test
Almost all invocations of run-test have either "$* on $(TARGET_NAME)"
or "$< on $(TARGET_NAME)" as the last argument.  So provide a default
test name, while allowing an escape hatch for custom names.

As an additional simplification, remove the need to do shell quoting.

37b0dba45c tests/tcg: unify ppc64 and ppc64le Makefiles
Make tests/tcg/ppc64le include tests/tcg/ppc64 instead of duplicating

not vice versa, the tests have to be moved from tests/tcg/ppc64le/

a3e28f81fd tests: simplify Makefile invocation for tests/tcg
Remove the DOCKER_SCRIPT and TARGET variable from the Makefile invocation
for tests/tcg.  For DOCKER_SCRIPT, resolve the path to docker.py in configure;
for TARGET, move it to config-$(TARGET).mak and use a symbolic link to break
the cycle.

The symbolic link is still needed because tests/tcg includes dummy config files
for targets that are not buildable.  Once that is cleaned up, the symbolic link
will go away too.

duplication, but is a simpler approach because of test-avx's extra

If needed, a common library can be introduced later.

While at it, for consistency move all the -cpu max rules to the

950936681f target/i386: Make translator stop before the end of a page
Right now translator stops right *after* the end of a page, which
breaks reporting of fault locations when the last instruction of a
multi-insn translation block crosses a page boundary.

An implementation, like the one arm and s390x have, would require an
i386 length disassembler, which is burdensome to maintain. Another
alternative would be to single-step at the end of a guest page, but
this may come with a performance impact.

Fix by snapshotting disassembly state and restoring it after we figure
out we crossed a page boundary. This includes rolling back cc_op
updates and emitted ops.

15fc6badbd Hexagon (target/hexagon) fix bug in mem_noshuf load exception
The semantics of a mem_noshuf packet are that the store effectively
happens before the load.  However, in cases where the load raises an
exception, we cannot simply execute the store first.

This change adds a probe to check that the load will not raise an
exception before executing the store.

If the load is predicated, this requires special handling.  We check
the condition before performing the probe.  Since, we need the EA to
perform the check, we move the GET_EA portion inside CHECK_NOSHUF_PRED.

Test case added in tests/tcg/hexagon/mem_noshuf_exception.c

cab86dea1d Hexagon (target/hexagon) fix store w/mem_noshuf & predicated load
Call the CHECK_NOSHUF macro multiple times: once in the
fGEN_TCG_PRED_LOAD() and again in fLOAD().

Before this commit, a packet with a store and a predicated
load with mem_noshuf that gets encoded like this:

    { P0 = cmp.eq(R17,#0x0)
      memw(R18+#0x0) = R2
      if (!P0.new) R3 = memw(R17+#0x4) }

... would end up generating a branch over both the load
and the store like so:

    ...
    brcond_i32 loc17,$0x0,eq,$L1
    mov_i32 loc18,store_addr_1
    qemu_st_i32 store_val32_1,store_addr_1,leul,0
    qemu_ld_i32 loc16,loc7,leul,0
    set_label $L1
    ...

bb52a8a278 tests/tcg: compile system emulation tests as freestanding
System emulation tests do not run in a hosted environment, since they
do not link with libc.  They should only use freestanding headers
(float.h, limits.h, stdarg.h, stddef.h, stdbool.h, stdint.h,
stdalign.h, stdnoreturn.h) and should be compiled with -ffreestanding
in order to use the compiler implementation of those headers
rather than the one in libc.

Some tests are using inttypes.h instead of stdint.h, so fix that.

cd362defbb tests/tcg: merge configure.sh back into main configure script
tests/tcg/configure.sh has a complicated story.

In the beginning its code ran as part of the creation of config-target.mak
files, and that is where it placed the information on the target compiler.
However, probing for the buildability of TCG tests required multiple
inclusions of config-target.mak in the _main_ Makefile (not in
Makefile.target, which took care of building the QEMU executables in
the pre-Meson era), which polluted the namespace.

Thus, it was moved to a separate directory.  It created small config-*.mak
files in $(BUILD_DIR)/tests/tcg.  Those were also included multiple
times, but at least they were small and manageable; this was also an
important step in disentangling the TCG tests from Makefile.target.

Since then, Meson has allowed the configure script to go on a diet.
A few compilation tests survive (mostly for sanitizers) but these days
it mostly takes care of command line parsing, looking for tools, and
setting up the environment for Meson to do its stuff.

It's time to extend configure with the capability to build for more
than just one target: not just tests, but also firmware.  As a first
step, integrate all the logic to find cross compilers in the configure
script, and move tests/tcg/configure.sh back there (though as a
separate loop, not integrated in the one that generates target
configurations for Meson).

tests/tcg is actually very close to being buildable as a standalone
project, so I actually expect the compiler tests to move back to
tests/tcg, as a "configure" script of sorts which would run at Make
time after the docker images are built.  The GCC tree has a similar idea
of doing only bare-bones tree-wide configuration and leaving the rest
for Make time.

b17ab4705c target/arm: Fix sve2 ldnt1 and stnt1
For both ldnt1 and stnt1, the meaning of the Rn and Rm are different
from ld1 and st1: the vector and integer registers are reversed, and
the integer register 31 refers to XZR instead of SP.

Secondly, the 64-bit version of ldnt1 was being interpreted as
32-bit unpacked unscaled offset instead of 64-bit unscaled offset,
which discarded the upper 32 bits of the address coming from
the vector argument.

Thirdly, validate that the memory element size is in range for the
vector element size for ldnt1.  For ld1, we do this via independent
decode patterns, but for ldnt1 we need to do it manually.

d0a17829d0 tests/tcg: drop -cpu max from s390x sha512-mvx invocation
With -cpu max we get a warning:

  qemu-s390x: warning: 'msa5-base' requires 'kimd-sha-512'.

But dropping the -cpu max and it still runs fine.

2b4e8cf050 tests/tcg/s390x: Fix the exrl-trt* tests with Clang
The exrl-trt* tests use two pre-initialized variables for the
results of the assembly code:

    uint64_t r1 = 0xffffffffffffffffull;
    uint64_t r2 = 0xffffffffffffffffull;

But then the assembly code copies over the full contents
of the register into the output variable, without taking
care of this pre-initialized values:

        "    lgr %[r1],%%r1\n"
        "    lgr %[r2],%%r2\n"

The code then finally compares the register contents to
a value that apparently depends on the pre-initialized values:

    if (r2 != 0xffffffffffffffaaull) {
        write(1, "bad r2\n", 7);
        return 1;
    }

This all works with GCC, since the 0xffffffffffffffff got into
the r2 register there by accident, but it fails completely with
Clang.

Let's fix this by declaring the r1 and r2 variables as proper
register variables instead, so the pre-initialized values get
correctly passed into the inline assembly code.

f530ba8f8d tests/tcg/s390x: Fix mvc, mvo and pack tests with Clang
These instructions use addressing with a "base address", meaning
that if register r0 is used, it is always treated as zero, no matter
what value is stored in the register. So we have to make sure not
to use register r0 for these instructions in our tests. There was
no problem with GCC so far since it seems to always pick other
registers by default, but Clang likes to chose register r0, too,
so we have to use the "a" constraint to make sure that it does
not pick r0 here.
