This matches ld.bfd and ld.gold behavior. The change is simple enough
and avoid trouble to consumers (they don't have to change their Makefiles).
Side note: found while trying to build FreeBSD base system with lld.

Specifically, don't wrap between the {} of an empty constructor if the
"}" falls on column 81 and ConstructorInitializerAllOnOneLineOrOnePerLine
is set.
llvm-svn: 251406
Summary:
If this option is set, clang-format will always insert a line wrap, e.g.
before the first parameter of a function call unless all parameters fit
on the same line. This obviates the need to make a decision on the
alignment itself.
Use this style for Google's JavaScript style and add some minor tweaks
to correctly handle nested blocks etc. with it. Don't use this option
for for/while loops.

* Remove an unneccessary re-computaion on arch spec from the ELF file
* Use a local cache to optimize name based section lookups in symtab
parsing
* Optimize C++ method basename validation with replacing a regex with
hand written code
These modifications reduce the time required to parse the symtab from
large applications by ~25% (tested with LLDB as inferior)

Summary: After D13851 landed, we saw backend crashes when compiling the reduced test case included in this patch. The right fix seems to be to allow these vector types for expansion in instruction selection.

llvm-svn: 251401
Summary:
This change deprecates -m/+m dotest options (the options are still recognized but they print an
error message pointing to the new options) and adds a new lldb-mi test category instead. To just
run lldb-mi tests, use '-G lldb-mi'. To skip lldb-mi tests, use '--skip-category lldb-mi'. All
lldb-mi tests are marked as such using the getCategories method on the base MiTestCaseBase class
and the @lldbmi_test decorator is not needed. In case one still needs to annotate a specific test
function as an lldb-mi test, one can use the @add_test_categories(['lldb-mi']) decorator to
achieve that.

Summary:
Gdb-remote's async thread sent out the eBroadcastBitRunPacketSent message *before* actually
sending out the continue packet. Since it's this message the actually triggers the public state
transition, it could happen (and it did happen in TestAttachResume, which does an "process
interrupt" right after a continue) that we attempt to stop the inferior before it was actually
started (which obviously did not end well). This fixes the problem by moving the broadcast after
the packet was actually sent.

We want to insert no-op casts as close as possible to the def. This is
tricky when the cast is of a PHI node and the BasicBlocks between the
def and the use cannot hold any instructions. Iteratively walk EH pads
until we hit a non-EH pad.
This fixes PR25326.

The former syntax matches how the backend tablegen files represent

No functionality changed here, but the indentation is substantially
reduced and IMO the code is much easier to read. I've also added some
helpful comments.
This is just a clean-up I wrote while studying the code, and that has
been in my backlog for a while.

Use `getUnsignedMax` directly instead of special casing a wrapped
ConstantRange.
The previous code would have been "buggy" (and this would have been a
semantic change) if LLVM allowed !range metadata to denote full
ranges. E.g. in
%val = load i1, i1* %ptr, !range !{i1 1, i1 1} ;; == full set
ValueTracking would conclude that the high bit (IOW the only bit) in
%val was zero.
Since !range metadata does not allow empty or full ranges, this change
is just a minor stylistic improvement.

When taking the remainder of a value divided by a constant, visitREM()
attempts to convert the REM to a longer but faster sequence of instructions.
This conversion calls combine() on a speculative DIV instruction. Commit
rL250825 may cause this combine() to return a DIVREM, corrupting nearby nodes.
Flow eventually hits unreachable().
This patch adds a test case and a check to prevent visitREM() from trying
to convert the REM instruction in cases where a DIVREM is possible.

We've switched to Gold earlier because of a minor misconfiguration
of the BFD linker in Android NDK. It turns out, Gold has much bigger
problems:
https://sourceware.org/bugzilla/show_bug.cgi?id=19163
(a bug is actually in the android runtime loader, but it means that
gold does not work with android L and even M).
Switching back to BFD and adding a workaround by explicitly linking
libm to all tests.
