- during diagnostics the string representation for root was empty
and now is `(root)`
- retrofitted all other namespace-qualified type naming to elide
prefixing with root
closes#2032
* Fix codegen for splat - instead of giving vectors of length N
to shufflevector for both of the operands, it gives vectors of length
1. The mask vector is the only one that needs N elements.
* Separate Splat into SplatSrc and SplatGen; the `len` is not needed
once it gets to codegen since it is redundant with the result type.
* Refactor compile error for wrong vector element type so that the
compile error message is not duplicated in zig source code
* Improve implementation to correctly handle comptime values such as
undefined and lazy values.
* Improve compile error for bad vector element type to point to the
correct place.
* Delete dead code.
* Modify behavior test to use an array cast instead of vector element
indexing since I'm merging this splat commit out-of-order from
Shawn's patch set.
* update documentation
- move `@shuffle` to be sorted alphabetically
- remove mention of LLVM
- minor clarifications & rewording
* introduce ir_resolve_vector_elem_type to avoid duplicate compile
error message and duplicate vector element checking logic
* rework ir_analyze_shuffle_vector to solve various issues
* improve `@shuffle` to allow implicit cast of arrays
* the shuffle tests weren't being run
I change the semantics of the mask operand, to make it a little more
flexible. There is no real danger in this because it is a compile-error
if you do it the LLVM way (and there is an appropiate error to tell you
this).
v2: avoid problems with double-free
* `await @asyncCall` generates better code. See #3065
* `@asyncCall` works with a real `@Frame(func)` in addition to
a byte slice. Closes#3072
* `@asyncCall` allows passing `{}` (a void value) as the result
pointer, which uses the result location inside the frame.
Closes#3068
* support `await @asyncCall` on a non-async function. This is in
preparation for safe recursion (#1006).
