The whole purpose of the op-builders is to factor out the main functionalities behind the current onnx parsers and put them in a separate set of files (under the folder ./src/op/builder/ ) so they could be reused in different parts of the application. That is this is mainly a refactoring task; the passing of the already existing unit and verify tests should be the proof that the refactoring left the integrity of mgr intact.

Pull request overview

This PR refactors the QuantizeLinear and DequantizeLinear ONNX parsers by extracting their core functionality into reusable op-builders under src/op/builder/. This is part of a larger effort to make operator building logic reusable across different parts of the application.

Changes:

  • Created new op-builder implementations for quantizelinear and dequantizelinear operations
  • Extracted common transformation logic into a shared template function for both quantize and dequantize operations
  • Refactored existing ONNX parsers to delegate to the new op-builders

When y_scale_lens[axis] equals 1 in blocked quantization mode, the calculation at line 106 results in division by zero (si - 1 = 0). This edge case should be handled, either by validating that si must be greater than 1 for blocked quantization, or by treating si = 1 as a special case that doesn't require block_size_max calculation.

Suggested change
float di = x_lens[axis];
float si = y_scale_lens[axis];
float di = x_lens[axis];
float si = y_scale_lens[axis];
if(si <= 1.0f)
{
MIGRAPHX_THROW(op_name + ": y_scale(shape: " + to_string_range(y_scale_lens) +
") must have size > 1 along provided axis(" + to_string(axis) +
") for block granularity");

minor: Can we rename this from ctx to context or tester? ctx is used for the gpu context in the rest of the codebase.
