A SourceName can be a file or a function. It makes sense to attach this
information to a SourceCoverageView, seeing as views (1) already point
to the text corresponding to the relevant source code and (2) are
already used to render that text along with the SourceNames.
This is a nice cleanup which is independent of the upcoming html patch.
While we're at it, document the fields in SourceCoverageView.

Pull LineCoverageInfo out of SourceCoverageView and rename it so that it
doesn't conflict with another class of the same name in
CoverageSummaryInfo.h.
This cuts down on the amount of code we have to move into a `protected`
section of SourceCoverageView for the upcoming html patch. It also makes
the code a bit clearer: having two LineCoverageInfo's is strange.

32-bit Mach headers don't have reserved fields. When generating the
mapping for 32-bit headers leaving off the reserved field will result in
parse errors if the field is present in the yaml.
Added a CHECK-NOT line to ensure that mach_header.yaml isn't adding a
reserved field, and a test to ensure that the parser error gets hit with
32-bit headers.

This flag was introduced in r269655 with the new diagnostic handler for llc. Its
purpose was to keep the old behavior for some of the tests that didn't recover
well after an error. Those tests have been fixed, so now it's safe to remove the
flag entirely.
Fixes PR27759.

This patch changes single method of llvm-readobj.
It teaches SHT_GNU_verdef dumper to print version dependencies,
also it removes few fields from output that can be dumped with other keys
and slightly refactors code.
Testcase was also modified to match the changes.
Change is required for testcases of upcoming lld patches.

Try to be more clever about selecting the default format. When an existing
archive is used, use the type of the archive to determine the format. When
existing members are present, use the first member's format to determine the
format to use. If we are creating an empty archive (MRI mode) or are adding
non-object members, default to the current behaviour of using the host type due
to the lack of a better alternative. This aids in cross-compilation on Darwin
to non-Darwin platforms which rely on GNU format archives.

This change is motivated by an upcoming change to the metadata representation
used for CFI. The indirect function call checker needs type information for
external function declarations in order to correctly generate jump table
entries for such declarations. We currently associate such type information
with declarations using a global metadata node, but I plan [1] to move all
such metadata to global object attachments.
In bitcode, metadata attachments for function declarations appear in the
global metadata block. This seems reasonable to me because I expect metadata
attachments on declarations to be uncommon. In the long term I'd also expect
this to be the case for CFI, because we'd want to use some specialized bitcode
format for this metadata that could be read as part of the ThinLTO thin-link
phase, which would mean that it would not appear in the global metadata block.
To solve the lazy loaded metadata issue I was seeing with D20147, I use the
same bitcode representation for metadata attachments for global variables as I
do for function declarations. Since there's a use case for metadata attachments
in the global metadata block, we might as well use that representation for
global variables as well, at least until we have a mechanism for lazy loading
global variables.
In the assembly format, the metadata attachments appear after the "declare"
keyword in order to avoid a parsing ambiguity.

Just a follow on to r273207, I missed updating the printing of the fat magic
number when the universal file is a 64-bit universal file.

Otherwise it gets linked in by one of the dependencies of shared
libraries which may be too late and we end up with weird crashes in
std::call_once().

llvm-mc is a developer tool, as such it make sense for it to use new
features by default.
This doesn't change the user facing clang, which still defaults to non
relaxable relocations.
llvm-svn: 273014
This allows better catching of compiler errors since we can use
the override keyword to verify that methods are actually
overridden.
Also in this patch I've changed from storing a boolean Error
code everywhere to returning an llvm::Error, to propagate richer
error information up the call stack.

Summary:
The Mips implementation only covers the feature bits described by the ELF
e_flags so far. Mips stores additional feature bits such as MSA in the
.MIPS.abiflags section.
Also fixed a small bug this revealed where microMIPS wouldn't add the
EF_MIPS_MICROMIPS flag when using -filetype=obj.
