This module defines the internal slices data fill pass. +//! The purpose of this pass is to fill out nested slice values represented by SSA array values. +//! "Filling out" a nested slice specifically refers to making a nested slice's internal slice types +//! match up in their size. This pass is necessary for dynamic array operations to work in ACIR gen +//! as we need to have a known size for any memory operations. As slice types do not carry a size we +//! need to make sure all nested internal slices have the same size in order to accurately +//! read from or write to a nested slice. This pass ultimately attaches dummy data to any smaller internal slice types. +//! +//! A simple example: +//! If we have a slice of the type [[Field]] which is of length 2. The internal slices themselves +//! could be of different sizes, such as 3 and 4. An array operation on this nested slice would look +//! something like below: +//! array_get [Field 3, [Field 1, Field 1, Field 1], Field 4, [Field 2, Field 2, Field 2, Field 2]], index Field v0 +//! Will get translated into a new instruction like such: +//! array_get [Field 3, [Field 1, Field 1, Field 1, Field 0], Field 4, [Field 2, Field 2, Field 2, Field 2]], index Field v0 +//! +//! +//! TODO(#3188): Currently the pass only works on a single flattened block. This should be updated in followup work. +//! The steps of the pass are as follows: +//! - Process each instruction of the block to collect relevant slice size information. We want to find the maximum size that a nested slice +//! potentially could be. Slices can potentially be set to larger array values or used in intrinsics that increase or shorten their size. +//! - Track all array constants and compute an initial map of their nested slice sizes. The slice sizes map is simply a map of an SSA array value +//! to its array size and then any child slice values that may exist. +//! - We also track a map to resolve a starting array constant to its final possible array value. This map is updated on the appropriate instructions +//! such as ArraySet or any slice intrinsics. +//! - On an ArrayGet operation add the resulting value as a possible child of the original slice. In SSA we will reuse the same memory block +//! for the nested slice and must account for an internal slice being fetched and set to a larger value, otherwise we may have an out of bounds error. +//! Also set the resulting fetched value to have the same internal slice size map as the children of the original array used in the operation. +//! - On an ArraySet operation we set the resulting value to have the same slice sizes map as the original array used in the operation. Like the result of +//! an ArrayGet we need to also add the `value` for an ArraySet as a possible child slice of the original array. +//! - For slice intrinsics we set the resulting value to have the same slice sizes map as the original array the same way as we do in an ArraySet. +//! However, with a slice intrinsic we also increase the size for the respective slice intrinsics. +//! We do not decrement the size on intrinsics that could remove values from a slice. This is because we could potentially go back to the smaller slice size, +//! not fill in the appropriate dummies and then get an out of bounds error later when executing the ACIR. We always want to compute +//! what a slice maximum size could be. +//! - Now we need to add each instruction back except with the updated original array values. +//! - Resolve the original slice value to what its final value would be using the previously computed map. +//! - Find the max size as each layer of the recursive nested slice type. +//! For instance in the example above we have a slice of depth 2 with the max sizes of [2, 4]. +//! - Follow the slice type to check whether the SSA value is under the specified max size. If a slice value +//! is under the max size we then attach dummy data. +//! - Construct a final nested slice with the now attached dummy data and replace the original array in the previously +//! saved ArrayGet and ArraySet instructions. + +use crate::ssa::{ + ir::{ + basic_block::BasicBlockId, + dfg::CallStack, + function::Function, + function_inserter::FunctionInserter, + instruction::{Instruction, InstructionId, Intrinsic}, + post_order::PostOrder, + types::Type, + value::{Value, ValueId}, + }, + ssa_gen::Ssa, +};

This module defines the internal slices data fill pass. -//! The purpose of this pass is to fill out nested slice values represented by SSA array values. -//! "Filling out" a nested slice specifically refers to making a nested slice's internal slice types -//! match up in their size. This pass is necessary for dynamic array operations to work in ACIR gen -//! as we need to have a known size for any memory operations. As slice types do not carry a size we -//! need to make sure all nested internal slices have the same size in order to accurately -//! read from or write to a nested slice. This pass ultimately attaches dummy data to any smaller internal slice types. -//! -//! A simple example: -//! If we have a slice of the type [[Field]] which is of length 2. The internal slices themselves -//! could be of different sizes, such as 3 and 4. An array operation on this nested slice would look -//! something like below: -//! array_get [Field 3, [Field 1, Field 1, Field 1], Field 4, [Field 2, Field 2, Field 2, Field 2]], index Field v0 -//! Will get translated into a new instruction like such: -//! array_get [Field 3, [Field 1, Field 1, Field 1, Field 0], Field 4, [Field 2, Field 2, Field 2, Field 2]], index Field v0 -//! -//! -//! TODO(#3188): Currently the pass only works on a single flattened block. This should be updated in followup work. -//! The steps of the pass are as follows: -//! - Process each instruction of the block to collect relevant slice size information. We want to find the maximum size that a nested slice -//! potentially could be. Slices can potentially be set to larger array values or used in intrinsics that increase or shorten their size. -//! - Track all array constants and compute an initial map of their nested slice sizes. The slice sizes map is simply a map of an SSA array value -//! to its array size and then any child slice values that may exist. -//! - We also track a map to resolve a starting array constant to its final possible array value. This map is updated on the appropriate instructions -//! such as ArraySet or any slice intrinsics. -//! - On an ArrayGet operation add the resulting value as a possible child of the original slice. In SSA we will reuse the same memory block -//! for the nested slice and must account for an internal slice being fetched and set to a larger value, otherwise we may have an out of bounds error. -//! Also set the resulting fetched value to have the same internal slice size map as the children of the original array used in the operation. -//! - On an ArraySet operation we set the resulting value to have the same slice sizes map as the original array used in the operation. Like the result of -//! an ArrayGet we need to also add the `value` for an ArraySet as a possible child slice of the original array. -//! - For slice intrinsics we set the resulting value to have the same slice sizes map as the original array the same way as we do in an ArraySet. -//! However, with a slice intrinsic we also increase the size for the respective slice intrinsics. -//! We do not decrement the size on intrinsics that could remove values from a slice. This is because we could potentially go back to the smaller slice size, -//! not fill in the appropriate dummies and then get an out of bounds error later when executing the ACIR. We always want to compute -//! what a slice maximum size could be. -//! - Now we need to add each instruction back except with the updated original array values. -//! - Resolve the original slice value to what its final value would be using the previously computed map. -//! - Find the max size as each layer of the recursive nested slice type. -//! For instance in the example above we have a slice of depth 2 with the max sizes of [2, 4]. -//! - Follow the slice type to check whether the SSA value is under the specified max size. If a slice value -//! is under the max size we then attach dummy data. -//! - Construct a final nested slice with the now attached dummy data and replace the original array in the previously -//! saved ArrayGet and ArraySet instructions. - -use crate::ssa::{ - ir::{ - basic_block::BasicBlockId, - dfg::CallStack, - function::Function, - function_inserter::FunctionInserter, - instruction::{Instruction, InstructionId, Intrinsic}, - post_order::PostOrder, - types::Type, - value::{Value, ValueId}, - }, - ssa_gen::Ssa, -};
