Eli Friedman c0c182cce1 [llvm-cov] Rearrange entries in report index.
Files which don't contain any functions are likely useless; don't
include them in the main table. Put the links at the bottom of the
page, in case someone wants to figure out coverage for code inside
a macro.

Not sure if this is the best solution, but it seems like an
improvement.

Lang Hames 14a22a442d [RuntimeDyld][ORC] Add support for Thumb mode to RuntimeDyldMachOARM.
This patch adds support for thumb relocations to RuntimeDyldMachOARM, and adds
a target-specific flags field to JITSymbolFlags (so that on ARM we can record
whether each symbol is Thumb-mode code).

RuntimeDyldImpl::emitSection is modified to ensure that stubs memory is
correctly aligned based on the size returned by getStubAlignment().

Trying to keep this small to make it easy to merge to the 5.0 branch. We

Sanjay Patel c50e55d0e6 [InstCombine] narrow rotate left/right patterns to eliminate zext/trunc (PR34046)
I couldn't find any smaller folds to help the cases in:
https://bugs.llvm.org/show_bug.cgi?id=34046
after:
rL310141

The truncated rotate-by-variable patterns elude all of the existing transforms because 
of multiple uses and knowledge about demanded bits and knownbits that doesn't exist 
without the whole pattern. So we need an unfortunately large pattern match. But by 
simplifying this pattern in IR, the backend is already able to generate 
rolb/rolw/rorb/rorw for x86 using its existing rotate matching logic (although
there is a likely extraneous 'and' of the rotate amount). 

Note that rotate-by-constant doesn't have this problem - smaller folds should already 
produce the narrow IR ops.

Florian Hahn d68bc7ae8d [ARM] Emit error when ARM exec mode is not available.
Summary:
A similar error message has been removed from the ARMTargetMachineBase
constructor in r306939. With this patch, we generate an error message
for the example below, compiled with -mcpu=cortex-m0, which does not
have ARM execution mode.

    __attribute__((target("arm"))) int foo(int a, int b)
    {
        return a + b % a;
    }

    __attribute__((target("thumb"))) int bar(int a, int b)
    {
        return a + b % a;
    }

By adding this error message to ARMBaseTargetMachine::getSubtargetImpl,
we can deal with functions that set -thumb-mode in target-features.
At the moment it seems like Clang does not have access to target-feature
specific information, so adding the error message to the frontend will
be harder.

Erich Keane be89f4c565 Fix broken getAttributeSpellingListIndex for pragma attributes
We noticed when implementing a new pragma that the TableGen-generated function 
getAttributeSpellingListIndex() did not work for pragma attributes. It relies 
on the values in the enum AttributeList::Syntax and a new value 
AS_ContextSensitiveKeyword was added changing the value for AS_Pragma. 
Apparently no tests failed since no pragmas currently make use of the 
generated function.

To fix this we can move AS_Pragma back to the value that TableGen code expects. 
Also to prevent changes in the enum from breaking that routine again I added 
calls to getAttributeSpellingListIndex() in the unroll pragma code. That will 
cause some lit test failures if the order is changed. I added a comment to 
remind of this issue in the future.

This assumes we don’t need/want full TableGen support for 
AS_ContextSensitiveKeyword. It currently only appears in getAttrKind and no 
other TableGen-generated routines.

Tim Northover 9710338a56 Reapply Sema: allow imaginary constants via GNU extension if UDL overloads not present.
C++14 added user-defined literal support for complex numbers so that you
can write something like "complex<double> val = 2i". However, there is
an existing GNU extension supporting this syntax and interpreting the
result as a _Complex type.

This changes parsing so that such literals are interpreted in terms of
C++14's operators if an overload is present but otherwise falls back to
the original GNU extension.

(We now have more robust diagnostics for implicit conversions so the
libc++ test that caused the original revert still passes).

Florian Hahn fc4b3951e9 [ARM] Remove FeatureNoARM implies ModeThumb.
Summary:
By removing FeatureNoARM implies ModeThumb, we can detect cases where a
function's target-features contain -thumb-mode (enables ARM codegen for the
function), but the architecture does not support ARM mode. Previously, the
implication caused the FeatureNoARM bit to be cleared for functions with
-thumb-mode, making the assertion in ARMSubtarget::ARMSubtarget [1]
pointless for such functions.

This assertion is the only guard against generating ARM code for
architectures without ARM codegen support. Is there a place where we
could easily generate error messages for the user? At the moment, we
would generate ARM code for Thumb-only architectures. X86 has the same
behavior as ARM, as in it only has an assertion and no error message,
but I think for ARM an error message would be helpful. What do you
think?

For the example below, `llc -mtriple=armv7m-eabi test.ll -o -` will
generate ARM assembler (or fail with an assertion error with this patch).
Note that if we run the resulting assembler through llvm-mc, we get
an appropriate error message, but not when codegen is handled
through clang.

```
define void @bar() #0 {
entry:
  ret void
}

attributes #0 = { "target-features"="-thumb-mode" }
```

Benoit Belley d9017cc65e [Support] PR33388 - Fix formatv_object move constructor
formatv_object currently uses the implicitly defined move constructor,
but it is buggy. In typical use-cases, the problem doesn't show-up
because all calls to the move constructor are elided. Thus, the buggy
constructors are never invoked.

The issue especially shows-up when code is compiled using the
-fno-elide-constructors compiler flag. For instance, this is useful when
attempting to collect accurate code coverage statistics.

The exact issue is the following:

The Parameters data member is correctly moved, thus making the
parameters occupy a new memory location in the target
object. Unfortunately, the default copying of the Adapters blindly
copies the vector of pointers, leaving each of these pointers
referencing the parameters in the original object instead of the copied
one. These pointers quickly become dangling when the original object is
deleted. This quickly leads to crashes.

The solution is to update the Adapters pointers when performing a move.
The copy constructor isn't useful for format objects and can thus be
deleted.

This resolves PR33388.
