The '-coff' command line option has been removed. It was not used in any
test cases.
The patch reviewed by Michael Spencer.

This applies to __attribute__((pure)) as well, but 'const' is more interesting
because many of our builtins are marked 'const'.

Mark up additional instructions which are part of the function prologue as
MachineFrameSetup. These instructions are part of the function prologue,
emitted by the PEI pass to setup the stack for use in the activating frame.

The ARM::BLX instruction is an ARM mode instruction. The Windows on ARM target
is limited to Thumb instructions. Correctly use the thumb mode tBLXr
instruction. This would manifest as an errant write into the object file as the
instruction is 4-bytes in length rather than 2. The result would be a corrupted
object file that would eventually result in an executable that would crash at
runtime.

whether the definition of the template is visible rather than checking whether
the instantiated definition happens to be in an imported module.

If the source files referenced by a gcno file are missing, gcov
outputs a coverage file where every line is simply /*EOF*/. This also
occurs for lines in the coverage that are past the end of a file that
is found.
This change mimics gcov.
llvm-svn: 208149
In gcov, there's a -n/--no-output option, which disables the writing
of any .gcov files, so that it emits only the summary info on stdout.
This implements the same behaviour in llvm-cov.

Previously only the toplevel elements were expanded by expandElements().
Now we recursively call getReplacements() to expand input elements even
if they are in, say, in a group.

Summary:
Update our mangling to match the discussion on cxx-abi-dev.
This involves using a seq-id instead of an optional number.

This is similar to the getAlignment patch, but is done just for
completeness. It looks like we never call getSection on an alias. All the
tests still pass if the if is replaced with an assert.

Replace a large monolitic function, with per-table functions which all nicely
fit on my screen. I also added documentation to each function that describes
what kind of tables are generated and which information is contained and
switched to range based for loops. Finally, I run clang-format over the moved
code.
I spent a significant amount of time to understand this code when reasoning
about possible extensions to the diagnostic interface to support 'remark'
diagnostics. This change will definitely help such an implementation, but
already by itself it will save other people a lot of time when trying to
understand this functionality.
Even though the patch touches the full function, it is mostly mechanical. No
functional change intended. The generated tblgen files are identical.

Speculatively reverting due to a suspicious failure on a Windows
buildbot.
This reverts commit 10c37a012ea11596d44cd9059fe09c959caf30c8.

remove it from the list of unspilled registers. Otherwise the following
attempt to keep the stack aligned by picking an extra GPR register to
spill will not work as it picks up r11.

This makes it easier to see where a global ctor comes from, and it also makes
ASan's init order analyzer output easier to understand. gcc does this too,
but only in -fPIC mode for some reason. Don't do this for constructors with
explicit init priority.
Also prepend "sub_" before the 'I', that way regular constructors stay
lexicographically after symbols with init priority (because
ord('s') > ord('I')). gold seems to ignore the name of constructor symbols,
and ld only looks at the symbol if it includes an init priority, which this
patch doesn't change.

Summary:
When I initially introduced -pass-remarks, I thought it would be a
neat idea to make it additive. So, if one used it as:
$ llc -pass-remarks=inliner --pass-remarks=loop.*
the compiler would build the regular expression '(inliner)|(loop.*)'.
The more I think about it, the more I regret it. This is not how
other flags work. The standard semantics are right-to-left overrides.
This is how clang interprets -Rpass. And I think the two should be
compatible in this respect.

Reverting r208106 to reapply r208065 with a fix for the regression. The
issue was that the enum tried to be built even if the declaration hadn't
been constructed for debug info - presenting problems for enum templates
and typedefs of enums with names for linkage purposes.
Original commit message:
This regressed a little further 208055 though it was already a little
broken.
While the requiresCompleteType optimization should be implemented here.
Future (possibly near future) work.

BugReport doesn't take ownership of the bug type, so let the checker own the
the bug type. (Requires making the bug type mutable, which is icky, but which
is also what other checkers do.)
