Wei Mi 798e59b81f [SampleFDO] Add profile symbol list section to discriminate function being
cold versus function being newly added.

This is the second half of https://reviews.llvm.org/D66374.

Profile symbol list is the collection of function symbols showing up in
the binary which generates the current profile. It is used to discriminate
function being cold versus function being newly added. Profile symbol list
is only added for profile with ExtBinary format.

During profile use compilation, when profile-sample-accurate is enabled,
a function without profile will be regarded as cold only when it is
contained in that list.

Puyan Lotfi d719c50655 [llvm-ifs][IFS] llvm Interface Stubs merging + object file generation tool.
This tool merges interface stub files to produce a merged interface stub file
or a stub library. Currently it for stub library generation it can produce an
ELF .so stub file, or a TBD file (experimental). It will be used by the clang
-emit-interface-stubs compilation pipeline to merge and assemble the per-CU
stub files into a stub library.

The new IFS format is as follows:

--- !experimental-ifs-v1
IfsVersion:      1.0
Triple:          <llvm triple>
ObjectFileFormat: <ELF | TBD>
Symbols:
  _ZSymbolName: { Type: <type>, etc... }

Martin Storsjo 9438221785 [COFF] Add a ResourceSectionRef method for getting resource contents
This allows llvm-readobj to print the contents of each resource
when printing resources from an object file or executable, like it
already does for plain .res files.

This requires providing the whole COFFObjectFile to ResourceSectionRef.

This supports both object files and executables. For executables,
the DataRVA field is used as is to look up the right section.

For object files, ideally we would need to complete linking of them
and fix up all relocations to know what the DataRVA field would end up
being. In practice, the only thing that makes sense for an RVA field
is an ADDR32NB relocation. Thus, find a relocation pointing at this
field, verify that it has the expected type, locate the symbol it
points at, look up the section the symbol points at, and read from the
right offset in that section.

This works both for GNU windres object files (which use one single
.rsrc section, with all relocations against the base of the .rsrc
section, with the original value of the DataRVA field being the
offset of the data from the beginning of the .rsrc section) and
cvtres object files (with two separate .rsrc$01 and .rsrc$02 sections,
and one symbol per data entry, with the original pre-relocated DataRVA
field being set to zero).

Summary:
GNU --strip-unneeded strips debugging sections as well. Do that for llvm-objcopy as well.

Additionally, add a test that verifies we keep the .gnu_debuglink section. This apparently was not always the case, and I'm not sure which commit fixed it, but there doesn't appear to be any test coverage to make sure we continue to do so.

This fixes PR41043.

Summary:
The matchers for section/symbol related flags (e.g. `--keep-symbol=Name` or `--regex --keep-symbol=foo.*`) are currently just vectors that are matched linearlly. However, adding wildcard support would require negative matching too, e.g. a symbol should be removed if it matches a wildcard *but* doesn't match some other wildcard.

To make the next patch simpler, consolidate matching logic to a class defined in CopyConfig that takes care of matching.

George Rimar f0f38d9b9d [llvm-objdump] - Cleanup the error reporting.
The error reporting function are not consistent.

Before this change:

* They had inconsistent naming (e.g. 'error' vs 'report_error').
* Some of them reported the object name, others - dont.
* Some of them accepted the case when there was no error. (i.e. error code or Error had a success value).

This patch tries to cleanup it a bit.

It also renames report_error -> reportError, report_warning -> reportWarning
and removes a full stop from messages.

Summary:
rL367756 (f5c40cb) increases the dependency of LLVMOrcJIT on LLVMPasses.
In particular, symbols defined in LLVMPasses that are referenced by the
destructor of `PassBuilder` are now referenced by LLVMOrcJIT through
`Speculation.cpp.o`.

We believe that referencing symbols defined in LLVMPasses in the
destructor of `PassBuilder` is valid, and that adding to the set of such
symbols is legitimate. To support such cases, this patch adds LLVMPasses
to the set of libraries being linked when linking in LLVMOrcJIT causes
such symbols from LLVMPasses to be referenced.
