Alex Bennée 5842de5157 tests/tcg: skip the vma-pthread test on CI
We are getting a lot of failures that are not related to changes so
this could be a flaky test.

Ilya Leoshkevich d4846c33eb tests/tcg/multiarch: add vma-pthread.c
Add a test that locklessly changes and exercises page protection bits
from various threads. This helps catch race conditions in the VMA
handling.

Alex Bennée 2bc6c79417 tests/tcg: fix unused variable in linux-test
The latest hexagon compiler picks up that we never consume wcount.
Given the name of the #define that rcount checks against is WCOUNT_MAX
I figured the check just got missed.

Finish weaning user-only away from PageDesc.

Using an interval tree to track page permissions means that

Markus Armbruster 66997c42e0 cleanup: Tweak and re-run return_directly.cocci
Tweak the semantic patch to drop redundant parenthesis around the
return expression.

Coccinelle drops a comment in hw/rdma/vmw/pvrdma_cmd.c; restored
manually.

Coccinelle messes up vmdk_co_create(), not sure why.  Change dropped,
will be done manually in the next commit.

Line breaks in target/avr/cpu.h and hw/rdma/vmw/pvrdma_cmd.c tidied up
manually.

Whitespace in tools/virtiofsd/fuse_lowlevel.c tidied up manually.

checkpatch.pl complains "return of an errno should typically be -ve"
two times for hw/9pfs/9p-synth.c.  Preexisting, the patch merely makes
it visible to checkpatch.pl.

Paolo Bonzini 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.

The two more or less overlap, because CONFIG_LINUX is a requirement for Linux
user-mode emulation.  However, CONFIG_LINUX is technically a host symbol
that applies even to system emulation.  Defining CONFIG_LINUX_USER, and
CONFIG_BSD_USER for eventual future use, is cleaner.

We had some messy code to filter out stuff we can't build. Lets junk
that and simplify the logic by pushing some stuff into subdirs. In
particular we move:

  float_helpers into libs - not a standalone test
  linux-test into linux - so we only build on Linux hosts

This allows for at least some of the tests to be nominally usable
by *BSD user builds.

The check_aligned_anonymous_unfixed_mmaps and

memory access.

legacy code. As we no longer do quite so much needless memory access
we can also remove the hexagon timeout hack.

Peter Maydell a930cadd83 tests/tcg/multiarch/Makefile.target: Disable run-gdbstub-sha1 test
Disable the run-gdbstub-sha1 test: it provokes an internal error
assertion failure in Ubuntu gdb 8.1.1-0ubuntu1 (Ubuntu gdb
8.1-0ubuntu3.2 also has this assert but we were previously skipping
this test because it doesn't support connection over local domain
sockets) :

A problem internal to GDB has been detected,
further debugging may prove unreliable.

Richard Henderson 51f22c195b tests/tcg/linux-test: Adjust getsockname for musl
Unlike glibc, musl does not use transparent unions to hide
the different structures that overlap struct sockaddr.

Add an explicit cast to work around this.

Alex Bennée 8ec6f33151 tests/tcg: better detect confused gdb which can't connect
While we may gamely give the right information it can still confuse
the wide range of GDBs out there. For example ppc64abi32-linux-user
reports:

  warning: Selected architecture powerpc:common is not compatible with reported target architecture powerpc:common64
  warning: Architecture rejected target-supplied description

but still connects. Add a test for a 0 pc and exit early if that is
the case. This may actually be a bug we need to fix?

Alex Bennée df3ca22318 tests/tcg: add a multiarch linux-user gdb test
When the gdbstub code was converted to the new API we missed a few
snafus in the various guests. Add a simple gdb test script which can
be used on all our linux-user guests to check for obvious failures.

Alex Bennée b059a62bb6 tests/tcg: add generic version of float_convs
This is broadly similar to the existing fcvt test for ARM but using
the generic float testing framework. We should be able to pare down
the ARM fcvt test case to purely half-precision with or without the
Alt HP provision.
