[LLVMdev] X86AsmPrinter + MASM and NASM backends
...pp files for how they are
written as examples.
3. Please #include X86ASmPrinter.h first in X86asmPrinter.cpp (see the
coding standard for justification). This will expose the fact that the
.h file needs some #includes to be self contained.
4. I think it would be a good idea to make the isScale/isMem methods
inline in the header file, even if that means more #includes are
needed in the .h file. These are pretty performance sensitive for the
printers, so it would be good for them to be inlined.
5. Please add #include guards around the headers (#ifndef XX_H/#define
XX_H),...

RFC: Interface user provided vector functions with the vectorizer.
For example, Type 2 case, scalar-foo used call by value while vector-foo used call by ref. The question Johannes is asking is whether we can decipher that after the fact, only by looking at the two function signatures, or need some more info (what kind, what's minimal)? I think we need to list up cases of interest, and for each vector ABI of interest, we need to work on the requirements and

[LLVMdev] X86AsmPrinter + MASM and NASM backends
I have "refactored" the X86AsmPrinter into a number of files ready for the MASM and NASM backends to be added.
There is a new namespace llvm::X86 to replace the anomonous namespace as this does not work accross mutiple .h and .cpp files. Other than that everything is pritty straight forward, t may possibly need tweeking though.
It has been built under MS VS2003, but I am not sure how

RFC: Interface user provided vector functions with the vectorizer.
...attached to each parameter and describes things like uniformity, linearity (with and without modifiers). The list of parameter types is then stored in the VectorFunctionShape:
struct VectorFunctionShape {
unsigned VF; // Vectorization factor
bool IsMasked;
bool IsScalable;
ISAKind ISA;
std::vector<ParamType> Parameters; };
Here OpenMP is used to classify the parameter types (OMP_*), but nothing prevents the ParamKind and the VectorFunctionShape to be extended to be able to handle other vector paradigms.
I think that we have to han...

[RFC] Supporting ARM's SVE in LLVM
...vector types without knowing their
exact length.
## IR Interface:
```cpp
static VectorType *get(Type *ELType, ElementCount EC);
// Legacy interface whilst code is migrated.
static VectorType *get(Type *ElType, unsigned NumEls, bool Scalable=false);
ElementCount getElementCount();
bool isScalable();
```
## IR Textual Form:
The textual IR for vectors becomes:
`<[n x] <m> x <type>>`
where `type` is the scalar type of each element, `m` corresponds to `Min` and
the optional string literal `n x ` signifies `Scalable` is *true* when present,
false otherwise. The textual...
