Richard Smith 05cdf4acf4 Consider reference, pointer, and pointer-to-member TemplateArguments to be different if they have different types.
For the Itanium ABI, this implements the mangling rule suggested in
https://github.com/itanium-cxx-abi/cxx-abi/issues/47, namely mangling
such template arguments as being cast to the parameter type in the case
where the template name is overloadable. This can cause a mangling
change for rare cases, where

 * the template argument declaration is converted from its declared type
   to the type of the template parameter, and
 * the template parameter either has a deduced type or is a parameter of
   a function template.

However, such changes are necessary to avoid mangling collisions. The
ABI changes can be reversed with -fclang-abi-compat=11 or earlier.

Re-commit with a fix for the regression introduced last time: don't
expect parameters and arguments to line up inside an <unresolved-name>
mangling.

Melanie Blower 320af6b138 Create SPIRABIInfo to enable SPIR_FUNC calling convention.
Background: Call to library arithmetic functions for div is emitted by the
compiler and it set wrong “C” calling convention for calls to these functions,
whereas library functions are declared with `spir_function` calling convention.
InstCombine optimization replaces such calls with “unreachable” instruction.
It looks like clang lacks SPIRABIInfo class which should specify default
calling conventions for “system” function calls. SPIR supports only
SPIR_FUNC and SPIR_KERNEL calling convention.

Jan Svoboda 6baa9769ed [clang][cli] Add flexible TableGen multiclass for boolean options
This introduces more flexible multiclass for declaring two flags controlling the same boolean keypath.

Compared to existing Opt{In,Out}FFlag multiclasses, the new syntax makes it easier to read option declarations and reason about the keypath.

This also makes specifying common properties of both flags possible.

I'm open to suggestions on the class names. Not 100% sure the benefits are worth the added complexity.

Andrzej Warzynski 764690b8a8 [clang] Remove `-triple` from the invocations of `flang-new -fc1`
This is just a small change in the Flang tool within libclangDriver.
Currently it passes `-triple` when calling `flang-new -fc1` for various
driver Jobs. As there is no support for code-generation, `-triple` is
not required and should remain unsupported. It is safe to remove it.

This hasn't been a problem as the affected driver Jobs are not yet
implemented or used. However, we will be adding support for them in the
near future and the fact `-triple` is added will become a problem.

Peter Waller 2315e9874c [AArch64][Driver][SVE] Push missing SVE feature error from driver to frontend
... and give more guidance to users.

If specifying -msve-vector-bits on a non-SVE target, clang would say:

    error: '-msve-vector-bits' is not supported without SVE enabled

1. The driver lacks logic for "implied features".
   This would result in this error being raised for -march=...+sve2,
   even though +sve2 implies +sve.

2. Feature implication is well modelled in LLVM, so push the error down
   the stack.

3. Hint to the user what flag they need to consider setting.

Now clang fails later, when the feature is used, saying:

  aarch64-sve-vector-bits.c:42:41: error: 'arm_sve_vector_bits' attribute is not supported on targets missing 'sve'; specify an appropriate -march= or -mcpu=
