Fred Riss a4a00ced0c [lldb/Module] Allow for the creation of memory-only modules
Summary:
This patch extends the ModuleSpec class to include a
DataBufferSP which contains the module data. If this
data is provided, LLDB won't try to hit the filesystem
to create the Module, but use only the data stored in
the ModuleSpec.

Jonas Devlieghere cdc514e4c6 [lldb] Update header guards to be consistent and compliant with LLVM (NFC)
LLDB has a few different styles of header guards and they're not very
consistent because things get moved around or copy/pasted. This patch
unifies the header guards across LLDB and converts everything to match
LLVM's style.

Benjamin Kramer adcd026838 Make llvm::StringRef to std::string conversions explicit.
This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.

This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.

This doesn't actually modify StringRef yet, I'll do that in a follow-up.

Pavel Labath a2e270fa70 unittests: Use yaml2obj as a library instead of an external process
Summary:
Recently, yaml2obj has been turned into a library. This means we can use
it from our unit tests directly, instead of shelling out to an external
process. This patch does just that.

Greg Clayton 8a7779209d Include inlined functions when figuring out a contiguous address range
Checking this in for Antonio Afonso:

This diff changes the function LineEntry::GetSameLineContiguousAddressRange so that it also includes function calls that were inlined at the same line of code.

My motivation is to decrease the step over time of lines that heavly rely on inlined functions. I have multiple examples in the code base I work that makes a step over stop 20 or mote times internally. This can easly had up to step overs that take >500ms which I was able to lower to 25ms with this new strategy.

The reason the current code is not extending the address range beyond an inlined function is because when we resolve the symbol at the next address of the line entry we will get the entry line corresponding to where the original code for the inline function lives, making us barely extend the range. This then will end up on a step over having to stop multiple times everytime there's an inlined function.

To check if the range is an inlined function at that line I also get the block associated with the next address and check if there is a parent block with a call site at the line we're trying to extend.

To check this I created a new function in Block called GetContainingInlinedBlockWithCallSite that does exactly that. I also added a new function to Declaration for convinence of checking file/line named CompareFileAndLine.

To avoid potential issues when extending an address range I added an Extend function that extends the range by the AddressRange given as an argument. This function returns true to indicate sucess when the rage was agumented, false otherwise (e.g.: the ranges are not connected). The reason I do is to make sure that we're not just blindly extending complete_line_range by whatever GetByteSize() we got. If for some reason the ranges are not connected or overlap, or even 0, this could be an issue.

I also added a unit tests for this change and include the instructions on the test itself on how to generate the yaml file I use for testing.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Tim Hammerquist a6db41675c cmake + xcode: prevent gtests from using includes from project root
Summary:
At present, several gtests in the lldb open source codebase are using
#include statements rooted at $(SOURCE_ROOT)/${LLDB_PROJECT_ROOT}.

This patch cleans up this directory/include structure for both CMake and
Xcode build systems.
