llvm-svn: 330070
Roman Tereshin [Fri, 13 Apr 2018 21:22:24 +0000 (21:22 +0000)]
[DebugInfo][OPT] Fixing a couple of DI duplication bugs of CloneModule
As demonstrated by the regression tests added in this patch, the
following cases are valid cases:
1. A Function with no DISubprogram attached, but various debug info
related to its instructions, coming, for instance, from an inlined
function, also defined somewhere else in the same module;
2. ... or coming exclusively from the functions inlined and eliminated
from the module entirely.
The ValueMap shared between CloneFunctionInto calls within CloneModule
needs to contain identity mappings for all of the DISubprogram's to
prevent them from being duplicated by MapMetadata / RemapInstruction
calls, this is achieved via DebugInfoFinder collecting all the
DISubprogram's. However, CloneFunctionInto was missing calls into
DebugInfoFinder for functions w/o DISubprogram's attached, but still
referring DISubprogram's from within (case 1). This patch fixes that.
The fix above, however, exposes another issue: if a module contains a
DISubprogram referenced only indirectly from other debug info
metadata, but not attached to any Function defined within the module
(case 2), cloning such a module causes a DICompileUnit duplication: it
will be moved in indirecty via a DISubprogram by DebugInfoFinder first
(because of the first bug fix described above), without being
self-mapped within the shared ValueMap, and then will be copied during
named metadata cloning. So this patch makes sure DebugInfoFinder
visits DICompileUnit's referenced from DISubprogram's as it goes w/o
re-processing llvm.dbg.cu list over and over again for every function
cloned, and makes sure that CloneFunctionInto self-maps
DICompileUnit's referenced from the entire function, not just its own
DISubprogram attached that may also be missing.
The most convenient way of tesing CloneModule I found is to rely on
CloneModule call from `opt -run-twice`, instead of writing tedious
unit tests. That feature has a couple of properties that makes it hard
to use for this purpose though:
1. CloneModule doesn't copy source filename, making `opt -run-twice`
report it as a difference.
2. `opt -run-twice` does the second run on the original module, not
its clone, making the result of cloning completely invisible in opt's
actual output with and without `-run-twice` both, which directly
contradicts `opt -run-twice`s own error message.
This patch fixes this as well.

Allow relative file paths when settings source breakpoints
Many IDEs set breakpoints using absolute paths and this causes problems when the full path of the source file path doesn't match what is in the debug info. This can be due to different build systems and do or do not resolve symlinks. This patch allows relative breakpoint to be set correctly without needing to do any target.source-map tricks. If IDEs want to, they can send down relative paths like:
./main.c
./src/main.c
src/main.c
foo/bar/src/main.c
I used the breakpoint resolver to match on the file basename and then we weed out anything whose relative paths don't match. This will be a huge improvement for IDEs as they can specify as much of a relative path as desired to uniquely identify a source file in the current project.

Prevent deadlock in OS Plugins
Summary:
When performing a synchronous resume, the API mutex is held until the
process is stopped. This is fine, except for when the OS plugins are processing
an event before the main thread is aware of it, in which case we end up with a
deadlock because in the internal thread we acquire a resource lock first, and
then wait for the API lock, while in the main thread we do the opposite, we
already hold the API mutex but are now waiting for the event mutex to handle
the event.
This patch fixes this by relaxing the need for the API lock in the OS plugins.
We can get away with this because we now this code is executed in the main
thread. As stated in the comment above, we just want to ensure nobody else
messes with the API while we're making a change. In theory it's possible that
the main thread would release the lock while we're executing the function, but
prevent this would require a more structural solution (which we want, but do
not have today).
The same workaround was already present, but this patch generalizes it to the
whole file.
This will allow me to re-land r329891.
