* Added peer type resolution for arrays and vectors: the vector type is
selected.
* Fixed passing the lhs type or rhs type instead of the peer resolved
type when calling Value methods during analyzeArithmetic handling of
comptime expressions.
* `checkVectorizableBinaryOperands` now allows mixing vectors and
arrays, as long as one of the operands is a vector.
This matches stage1's handling of `^=` but apparently stage1 is
inconsistent and does not handle e.g. `*=`. stage2 now will always allow
mixing vector and array operands for all operations.
Although lazy_align is a different tag than integer values, it needs to
be hashed and equality-tested as if it were a simple integer. Otherwise
our basic data structure guarantees fall apart.
We are putting off actual optimization of floats because we have a
couple proposals being considered which would change how it works.
In the meantime, lowering optimized float mode to be the same as
strict is a perfectly legal way to implement the Zig language specification.
Otherwise, we risk tripping an assertion in `Type.errorSetNames()`
in case the inferred error set was not yet fully resolved. This so
far only surfaced when Dwarf triggers recursive analysis of an
error set as part of emitting debug info for an error union.
This implements the overflow arithmetic for unsigned and signed integers.
Meaning the following instructions:
- @addWithOverflow
- @subWithOverflow
- @shlWithOverflow
- @mulWithOverflow
Instead, we fallback to the old-fashioned stabs-based mechanism
until I add the missing mechanism for extracting and relocating
DWARF from relocatable object files and writing it into a dSYM
bundle.
continuation of #11093 to simplify testing IPC
* use cases
- get path to temporary directory
- get the test arguments inside test block for reusage
- build executables from text within test blocks, ie to test IPC
* missing conventions
- how to name and debug test cases
- where do simple+repititve build commands for testing belong
This file contains a collections of functions that may be useful for SIMD, such as generating a vector with a linear range of numbers starting at zero, joining two vectors together, getting the index of the first true in a vector of bools, etc.
Rather than creating an import for externs on updateDecl, we now
generate them when they're referenced. This is required so using @TypeOf(extern_fn())
will not emit the import into the binary (causing an incorrect function type index
as it won't be fully analyzed).
