There was CMake code that would attempt to detect Python 3 even if
LLVM was configured with Python 2, but it messed with the environment
for the other LLVM projects. This commit removes this functionality
and just lkeaves a hard error if Python < 3 is detected and
debuginfo-tests are required.
First, add LLD as a dependency on Windows. The windows batch scripts
pass -fuse-ld=lld, so they need it.
Second, decode builder stdout/stderr even if the command fails.
Otherwise it gets printed as b'line 1\n\rline 2\n\r'.
Last, make the batch script one line less noisy. We might want to try to
do more here, though. It would be nice if we could get as close to
possible as lit, where you can literally copy & paste the failing
command to re-run it.
With the two changes above, now the feature tests that use clang++.bat
pass for me. The clang-cl_vs2015 ones still fail, and I'll fix them
separately.

LLDB already requires Python 3 on Windows, so I already configure it
that way. For some reason CMake fails to find the one that Visual Studio
automatically installs at this standard location:
C:/Program Files (x86)/Microsoft Visual Studio/Shared/Python37_64/python.exe
CMake prefers the python on path, which happens to be python 2.7.

This reverts commit cb935f3456.
Discussion in D68708 advises that green dragon is being briskly
refurbished, and it's good to have this patch up testing it.
Dexter (Debug Experience Tester) is a test-driver for our debug info
integration tests, reading a set of debug experience expectations and
comparing them with the actual behaviour of a program under a debugger.
More about Dexter can be found in the RFC:
http://lists.llvm.org/pipermail/llvm-dev/2019-October/135773.html
and the phab review in D68708. Not all the debuginfo tests have been
transformed into Dexter tests, and we look forwards to doing that
incrementally.
This commit mostly aims to flush out buildbots that are running
debuginfo-tests but don't have python 3 installed, possibly
green-dragon and some windows bots.
This is an initial prototype of how we can run debugger integration
tests on Windows. cdb and windbg share a command language and debugger
engine. Visual Studio has its own, but we should at least be able to use
cdb as the basis for optimized debug info integration tests.
There's a lot of work to do here still. For example:
- Make fewer assumptions about the SDK location
- Don't assume x64 (important, I need x86 testing)
- More environment isolation, have lit setup vcvars instead of passing
LIB and INCLUDE down.
- Write a .py file to replace the grep+sed RUN line
But, this seemed like a good enough concept to commit as is, since it's
useful to me already.

These sections will be retired. Also, explicitly list llvm-objdump
as a dependency. This should've been done in the previous commit,
but I failed to squash the two changes together.
Thanks to Adrian for pointing the first problem out in a comment.

Summary:
Add cmake and lit files needed to run these tests as an
external project. Also, copy test_debuginfo.pl from llvm/utils since
it's only used here. The copy in llvm/utils must be maintained as
long as bots continue to include debuginfo-tests in clang/test.
This patch depends on clang patch https://reviews.llvm.org/D41055.

This is still breaking greendragon.
At this point I give up until someone can fix the greendragon
bots, and I will probably abandon this effort in favor of using
a private github repository.

This was reverted due to the tests being run twice on some
build bots. Each run had a slightly different configuration
due to the way in which it was being invoked. This fixes
the problem (albeit in a somewhat hacky way). Hopefully in
the future we can get rid of the workflow of running
debuginfo-tests as part of clang, and then this hack can
go away.
llvm-svn: 318697
This is still broken because it causes certain tests to be
run twice with slightly different configurations, which is
wrong in some cases.
You can observe this by running:
ninja -nv check-all | grep debuginfo-tests
And seeing that it passes clang/test and clang/test/debuginfo-tests
to lit, which causes it to run debuginfo-tests twice. The fix is
going to involve either:
a) figuring out that we're running in this "deprecated" configuration,
and then deleting the clang/test/debuginfo-tests path, which should
cause it to behave identically to before, or:
b) make lit smart enough that it doesn't descend into a sub-suite if
that sub-suite already has a lit.cfg file.
llvm-svn: 318486
This was reverted due to some failures on specific darwin buildbots,
the issue being that the new lit configuration was not setting the
SDKROOT environment variable. We've tested a fix locally and confirmed
that it works, so this patch resubmits everything with the fix
applied.
llvm-svn: 318435
This reverts the aforementioned patch and 2 subsequent follow-ups,
as some buildbots are still failing 2 tests because of it.
Investigation is ongoing into the cause of the failures.
llvm-svn: 318112
Previously, debuginfo-tests was expected to be checked out into
clang/test and then the tests would automatically run as part of
check-clang. This is not a standard workflow for handling
external projects, and it brings with it some serious drawbacks
such as the inability to depend on things other than clang, which
we will need going forward.
The goal of this patch is to migrate towards a more standard
workflow. To ease the transition for build bot maintainers,
this patch tries not to break the existing workflow, but instead
simply deprecate it to give maintainers a chance to update
the build infrastructure.
