Adrian Prantl dce4a9aa59 Look for external types in all clang modules imported by the current symbol file.
This fixes a bug in -gmodules DWARF handling when debugging without a .dSYM bundle
that was particularly noticable when debugging LLVM itself.

Debugging without clang modules and DWO handling should be unaffected by this patch.

Pavel Labath b8318155eb Enable TestReadMemCString on non-darwin targets
The test works fine on linux, and I believe other targets should not
have an issue with as well. If they do, we can start blacklisting
instead of whitelisting.

The idea of using "-1" as the value of the pointer on non-apple targets
backfired, as it fails the "address != LLDB_INVALID_ADDRESS" test (-1 is
the value of LLDB_INVALID_ADDRESS).  However, it should be safe to use
0x100 for other targets as well. The first page of memory is generally
kept unreadable to catch null pointer dereferences.

Pavel Labath 3db29a1b3e Work around test failures on red-hat linux
Two tests were failing because the debugger was picking up multiply
defined internal symbols from the system libraries. This is a bug, as
there should be no ambiguity because the tests are defining variables
with should shadow these symbols, but lldb is not smart enough to figure
that out.

I work around the issue by renaming the variables in these tests, and in
exchange I create a self-contained test which reproduces the issue
without depending on the system libraries.

This increases the predictability of our test suite.

Davide Italiano 53cff5161c [testsuite] Remove testing failures vestiges.
Some tests are failing on macOS when building with the in-tree
clang, and this is because they're conditional on the version released.
Apple releases using a different versioning number, but as these are
conditional on clang < 7, they fail for clang ToT (which is 6.0).
As a general solution, we actually need either a mapping between
Apple internal release version and public ones.

That said, I discussed this with Fred , and Apple Clang 6.0 seems
to be old enough that we can remove this altogether (which means I
can delay implementing the general purpose solution for a bit).

Pavel Labath fd9a526a30 Makefile.rules: compile all tests with -fno-limit-debug-info
Summary:
This flag is on by default for darwin and freebsd, but off for linux.
Without it, clang will sometimes not emit debug info for types like
std::string. Whether it does this, and which tests will fail because of
that depends on the linux distro and c++ library version.

A bunch of tests were already setting these flags manually, but here
instead I take a whole sale approach and enable this flag for all tests.
Any test which does not want to have this flag (right now we have one
such test) can turn it off explicitly via
CFLAGS_EXTRAS+=$(LIMIT_DEBUG_INFO_FLAGS)

This fixes a bunch of data formatter tests on red-hat.

Pavel Labath d2cfe0e597 Fix floating point register write on new x86 linux kernels
Summary:
New linux kernels (on systems that support the XSAVES instruction) will
not update the inferior registers unless the corresponding flag in the
XSAVE header is set. Normally this flag will be set in our image of the
XSAVE area (since we obtained it from the kernel), but if the inferior
has never used the corresponding register set, the respective flag can
be clear.

This fixes the issue by making sure we explicitly set the flags
corresponding to the registers we modify. I don't try to precisely match
the flags to set on each write, as the rules could get quite complicated
-- I use a simpler over-approximation instead.

This was already caught by test_fp_register_write, but that was only
because the code that ran before main() did not use some of the register
sets. Since nothing in this test relies on being stopped in main(), I
modify the test to stop at the entry point instead, so we can be sure
the inferior did not have a chance to access these registers.

Summary:
This test was failing in various configurations on linux in a fairly
unpredictible way. The success depended on whether the c++ abi library
was linked in statically or not and how well was the linker able to
strip parts of it. This introduces additional code to the "dummmy" test
executable, which ensures that all parts of the library needed to
evaluate the expressions are always present.

Pavel Labath 881fe8ecb2 "Fix" concurrent events test for arm
Summary:
The test incremented an atomic varible to trigger the watchpoint event.
On arm64 this compiled to a ldaxr/stlxr loop, with the watchpoint being
triggered in the middle of the loop. Hitting the watchpoint resets the
exclusive monitor, and forces the process to loop one more time, hitting
the watchpoint again, etc.

While it would be nice if the debugger was able to resume from this
situation, this is not trivial, and is not what this test is about.
Therefore, I propose to change this to a simple store to a normal
variable (which should still trip the watchpoint everywhere, but without
atomic loops) and file a bug to investigate the possibilities of
handling the watchpoints in atomic loops in a more reasonable way.
