* 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 docs for `@byteSwap`.
* fix hash & eql functions for ZigLLVMFnIdBswap not updated to
include vector len. this was causing incorrect bswap function
being called in unrelated code
* fix `@byteSwap` behavior tests only testing comptime and not
runtime operations
* implement runtime `@byteSwap`
* fix incorrect logic in ir_render_vector_to_array and
ir_render_array_to_vector with regards to whether or not to bitcast
* `@byteSwap` accepts an array operand which it will cast to vector
* simplify `@byteSwap` semantic analysis code and various fixes
* 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
* Add missing <stdint.h> include for uint8_t type declaration
* Add needed FreeBSD check to link to libpthread
* Apply patch to enable more tests in the FreeBSD CI
Sometimes the frontend and LLVM would disagree on the ABI alignment of a
packed union. Solve the problem by telling LLVM we're gonna manage the
struct layout by ourselves.
Closes#3184
- include native-target when native-target ∉ cross_targets
old behavior:
- do nothing when `-Dskip-non-native`
- never execute pkg tests for non-members of cross_targets
`zig build test-compare-panic`
Create basic tests to compare panic output. The address field
is replaced by a symbolic constant and each expected output is
specific to os. Tests will only run for explicitly defined
platforms.
