Gustavo Romero bb77c68dbd tests/tcg/aarch64: Use raw strings for regexes in test-mte.py
Use Python's raw string notation instead of string literals for regex so
it's not necessary to double backslashes when regex special forms are
used. Raw notation is preferred for regex and easier to read.

Gustavo Romero 06dd94e843 tests/tcg/aarch64: Extend MTE gdbstub tests to system mode
Extend MTE gdbstub tests to also run in system mode (share tests between
user mode and system mode). The tests will only run if a version of GDB
that supports MTE on baremetal is available in the test environment and
if available compiler supports the 'memtag' flag
(-march=armv8.5-a+memtag).

For the tests running in system mode, a page that supports MTE ops. is
necessary. Therefore, an MTE-enabled page is made available (mapped) in
the third 2 MB chunk of the second 1 GB space in the flat mapping set in
boot.S. A new binary, mte.S, is also introduced for the tests. It links
against boot.S and is executed by QEMU in system mode.

Ilya Leoshkevich 4d48c1bc07 tests/tcg: Factor out gdbstub test functions
Both the report() function as well as the initial gdbstub test sequence
are copy-pasted into ~10 files with slight modifications. This
indicates that they are indeed generic, so factor them out. While
at it, add a few newlines to make the formatting closer to PEP-8.

Alex Bennée a8fea70f65 tests/tcg: clean-up gdb confirm/pagination settings
We can do this all in the run-test.py script so remove the extraneous
bits from the individual tests which got copied from the original
non-CI gdb tests.

Alex Bennée 797920b952 target/arm: use official org.gnu.gdb.aarch64.sve layout for registers
While GDB can work with any XML description given to it there is
special handling for SVE registers on the GDB side which makes the
users life a little better. The changes aren't that major and all the
registers save the $vg reported the same. All that changes is:

  - report org.gnu.gdb.aarch64.sve
  - use gdb nomenclature for names and types
  - minor re-ordering of the types to match reference
  - re-enable ieee_half (as we know gdb supports it now)
  - $vg is now a 64 bit int
  - check $vN and $zN aliasing in test

Alex Bennée 744f1b0f68 tests/tcg: drop inferior.was_attached() test
This test seems flaky and reports attachment even when we failed to
negotiate the architecture. However the fetching of the guest
architecture will fail tripping up the gdb AttributeError which will
trigger our early no error status exit from the test

Alex Bennée d2fefdedd3 tests/tcg: better trap gdb failures
It seems older and non-multiarach aware GDBs might not fail gracefully
when faced with something they don't know. For example when faced with
a target XML for s390x the Ubuntu 18.04 gdb will generate an internal
fault and prompt for a core dump.

Work around this by invoking GDB in a more batch orientated way and
then trying to filter out between test failures and gdb failures.

Alex Bennée f4a23e1797 tests/tcg/aarch64: add test-sve-ioctl guest-debug test
This test exercises the gdbstub while runing the sve-iotcl test. I
haven't plubmed it into make system as we need a way of verifying if
gdb has the right support for SVE.

Alex Bennée cf58773f1c tests/tcg/aarch64: add a gdbstub testcase for SVE registers
A very simple test case which sets and reads SVE registers while
running a test case. We don't really need to compile a SVE binary for
this case but we will later so keep it simple for now.
