(#78653)"
This reverts commit 82bc33ea3f1a539be50ed46919dc53fc6b685da9.
Accidentally pushed unrelated changes.

Fix the bug where merge-fdata unconditionally outputs boltedcollection
line, regardless of whether input files have it set.
Test Plan:
Added bolt/test/X86/merge-fdata-nobat-mode.test which fails without this
fix.

Since Dexter no longer intends to build any code, the ShouldBuild
property in any Visual Studio project being run by Dexter should be
false to ensure that a build step is never invoked by Dexter, whether
the project has already been built or not.

The purpose of this example is to provide a case where the debugger /
debug info experience could be improved. A recent commit by clang
(0d2860b795879f4dd152963b52f969b53b136899) changed codegen such that it
changes how "small structs" are initialized, in a way that the debugger
is now able to correctly display the variable being targeted by this
test.
In order to keep the example relevant, i.e. failing, this commit makes
it so that the struct is now "big enough" to not trigger the new
codegen.

Currently if Dexter encounters a parser error with a command, the resulting
error message will refer to the most recently declared file (i.e. the source
file it is testing) rather than the file containing the command itself. This
patch fixes this so that parser errors point towards the correct location.

The issue with these test failures is that the dSYM was not being found
by lldb, which is why setting breakpoints was failing and lldb quit
without performing any steps. This change copies the dSYM to the same
temp directory that the executable is copied to.

The patch in https://reviews.llvm.org/D151465 broke greendragon, because

The optnone tests, following the removal of the Dexter builder in a
prior patch (45a40c16), are experiencing intermittent failures. This
patch marks them unsupported to be fixed in a new commit, rather than
reverting the Dexter patch.
|
|
This patch makes a further attempt to fix the tests broken by the
previous revision by ensuring that the command line for the modified
Dexter tests use -std=gnu++11, in keeping with the old build script.
This reverts commit 5647f2908de90fe07b0805e988cd2e91a1751928.

Re-application of the Dexter builder removal reversed due to continued
errors on the green dragon LLDB buildbot:
https://green.lab.llvm.org/green/view/LLDB/job/lldb-cmake/59716/
Cause of the error is unclear, but it looks as though there is some
unexpected non-determinism in the test failures.
This reverts commit 323270451d8db24f2c816f455b3d8f70f434286d.

Fixes a test which was broken on the green dragon buildbot, and further
failures on the SIE buildbot.
This reverts commit 8df9eff90ff8c79e3e508cce7fec1cd897487069.

The error message "Couldn't lookup symbols" emitted from IRExecutionUnit
is grammatically incorrect. "Lookup" is noun when spelled without a
space. Update the error message to use the verb "look up" instead.

& Revert "[Dexter] Fix incorrect substitution errors in clang-cl builder"
This reverts commits 262520a3c5450fd7f149438245b2aef12736347f,
and 0b72b71cd3c8ad824342c05bc6d9d64d87eeb81b.
Failures occurred on two buildbots, the SIE buildbot:
https://lab.llvm.org/buildbot/#/builders/216/builds/26006
And the green dragon buildbot:
https://green.lab.llvm.org/green/view/LLDB/job/lldb-cmake/59091
Errors appear to be related to incorrect tool substitution in the Dexter
test commands, and a currently unknown error with one of the general
debuginfo tests that uses Dexter.
|
|
Following 262520a3, tests on windows bots began failing due to an incorrect
substitution in the previous patch, where clang-cl was used instead of
clang_cl.
Also fixes an inconsistency in the builders used for some of the tests
in 'dexter-tests', where %clang++ was used for some tests and %clang for
tests that should have identical RUN lines.

See "discussion":
https://discourse.llvm.org/t/rfc-dexter-feature-removals/60462
This patch removes the builder functionality from Dexter, as it is an active
maintenance burden and is no longer required since Dexter is being invoked by
other test runners that can handle the build step better, and there has been no
objection that it is still needed.

This is an ongoing series of commits that are reformatting our
Python code. This catches the last of the python files to
reformat. Since they where so few I bunched them together.
Reformatting is done with `black`.
If you end up having problems merging this commit because you
have made changes to a python file, the best way to handle that
is to run git checkout --ours <yourfile> and then reformat it
with black.
If you run into any problems, post to discourse about it and
we will try to help.

Adds a pair of options for Dexter that allow the user to specify a
timeout duration. These options are:
* --timeout-total: Times out if the total run-time of the debugger session
exceeds <timeout-total> seconds.
* --timeout-breakpoint: Times out if the time without hitting a
breakpoint exceeds <timeout-breakpoint> seconds.

Adds a basic logging class to Dexter that uses the existing PrettyOutput
class for printing and supports 3 levels of verbosity (note, warning,
error). Intended to consolidate the logging logic for Dexter into one
place, removing the need for conditional log statements and making it
easier for us later if we wish to use a more complete logging class.

The Visual Studio debugger currently uses blocking calls to Go and

DexExpectStepOrder uses the line to expect a debugger step from the actual line
of the command in the Dexter source file. Now Dexter scripts have mainly moved
to thier own script files instead of the actual source, there should be a
option to override this behaviour to choose your own debugger step location.

The test case optnone-simple-functions.cpp is expected to be compiled
unoptimized even under -O2 because of attribute optnone. But this attribute is
missed for main function, and caused the fail in
https://lab.llvm.org/buildbot/#/builders/217/builds/14046 when it triggered
optimizations. This patch fixes that by adding attribute optnone to main
function.

The test dexter/feature_tests/commands/perfect/expect_step_kind/direction.cpp
was failing on a machine because __libc_start_call_main was not identified as a
"frame below main" (a frame we don't want to gather information from), causing
dexter to count one more step than expected in the test.
Add __libc_start_call_main to the list of "frames below main". There may
be a more robust way of doing this but this is a pragmatic solution we can
use for now.

The ArgumentPromotion pass uses Mem2Reg promotion at the end to cutting
down generated `alloca` instructions as well as meaningless `store`s and
this behavior can leave unused (dead) arguments. To eliminate the dead
arguments and therefore let the DeadCodeElimination remove becoming dead
inserted `GEP`s as well as `load`s and `cast`s in the callers, the
DeadArgumentElimination pass should be run after the ArgumentPromotion
one.

This test would previously expect one of the parameters to have
an incorrect DW_AT_location. Stepping through `fun` with a debugger
would then no reflect updates to one of the parameters.
With a recent change to Clang's DeadArgumentEliminationPass
(see `879f5118fc74657e4a5c4eff6810098e1eed75ac`) the generated
DWARF does not contain a location for `parama`, and stepping through
the function with `lldb` works as expected.

Summary:
This is an essential piece of infrastructure for us to be
continuously testing debug info with BOLT. We can't only make changes
to a test repo because we need to change debuginfo tests to call BOLT,
hence, this diff needs to sit in our opensource repo. But when upstreaming
to LLVM, this should be kept BOLT-only outside of LLVM. When upstreaming,
we need to git diff and check all folders that are being modified by our
commits and discard this one (and leave as an internal diff).
To test BOLT in debuginfo tests, configure it with -DLLVM_TEST_BOLT=ON.
Then run check-lldb and check-debuginfo.

One of the tests added in the recent floating point patch involves
string comparison against the debugger output; as DbgEng and LLDB have
different output, the test cannot pass against both of them, so disable
it on windows.
