ad5770eba4 organize behavior tests
* Identify the ones that are passing and stop skipping them.
 * Flatten out the main behavior.zig file and have each individual test
   disable itself if it is not passing.

8643591c9a CBE: split {clz,ctz,mod,popCount,byteSwap,bitReverse} by type
This also surfaces the fact that clz, ctz and popCount didn't actually
support 128 bit integers, despite what was claimed by
226fcd7c709ec664c5d883042cf7beb3026f66cb. This was partially hidden by
the fact that the test code for popCount only exercised 128 bit integers
in a comptime context. This commit duplicates that test case for runtime
ints too.

d0277a3d17 CBE: implement popCount, byteSwap, bitReverse for ints <= 128 bits
This folds the airCountZeroes() code from
226fcd7c709ec664c5d883042cf7beb3026f66cb back into airBuiltinCall(),
since most of these builtins happen to require the same arguments and
can be unified under a common function signature.

a005ac9d3c stage2: implement @popCount for SIMD vectors 2022-02-12 20:44:30 -07:00

93b854eb74 stage2: implement @ctz and @clz including SIMD
AIR:
 * `array_elem_val` is now allowed to be used with a vector as the array
   type.
 * New instructions: splat, vector_init

AstGen:
 * The splat ZIR instruction uses coerced_ty for the ResultLoc, avoiding
   an unnecessary `as` instruction, since the coercion will be performed
   in Sema.
 * Builtins that accept vectors now ignore the type parameter. Comment
   from this commit reproduced here:

   The accepted proposal #6835 tells us to remove the type parameter from
   these builtins. To stay source-compatible with stage1, we still observe
   the parameter here, but we do not encode it into the ZIR. To implement
   this proposal in stage2, only AstGen code will need to be changed.

Sema:
 * `clz` and `ctz` ZIR instructions are now handled by the same function
   which accept AIR tag and comptime eval function pointer to
   differentiate.
 * `@typeInfo` for vectors is implemented.
 * `@splat` is implemented. It takes advantage of `Value.Tag.repeated` 😎
 * `elemValue` is implemented for vectors, when the index is a scalar.
   Handling a vector index is still TODO.
 * Element-wise coercion is implemented for vectors. It could probably
   be optimized a bit, but it is at least complete & correct.
 * `Type.intInfo` supports vectors, returning int info for the element.
 * `Value.ctz` initial implementation. Needs work.
 * `Value.eql` is implemented for arrays and vectors.

LLVM backend:
 * Implement vector support when lowering `array_elem_val`.
 * Implement vector support when lowering `ctz` and `clz`.
 * Implement `splat` and `vector_init`.

Master branch added `try` to a bunch of testing function calls, and some
lines also had changed how to refer to the native architecture and other
`@import("builtin")` stuff.

4307436b99 move behavior tests from test/stage1/ to test/
And fix test cases to make them pass. This is in preparation for
starting to pass behavior tests with self-hosted.
