Andrew Kelley	380c8ec2c9	implement runtime @byteSwap and other fixups ... * 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	2019-09-19 00:59:04 -04:00

Andrew Kelley	2038f4d45a	rework the implementation ... * 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	2019-09-18 16:15:19 -04:00
Shawn Landden	193604c837	stage1: add @shuffle() shufflevector support ... 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	2019-09-18 11:26:45 -04:00

Shawn Landden	0e3ca4c63e	Fix array->vector and vector->array for many types. Allow vector of bool. ... Vectors do not have the same packing as arrays, and just bitcasting is not the correct way to convert them.	2019-09-18 09:52:58 -04:00

LemonBoy	8fbae77770	Force LLVM to generate byte-aligned packed unions ... 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	2019-09-10 10:07:32 -04:00

Andrew Kelley	5c3a9a1a3e	improvements to @asyncCall ... * `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).	2019-08-31 18:50:16 -04:00
