This PR adds comprehensive XML documentation to the core LLVM IR generator classes in src/Xamarin.Android.Build.Tasks/Utilities/LlvmIrGenerator/.

Changes Made

Core Infrastructure Classes

  • LlvmIrArraySection.cs - Added documentation for array section base and generic classes used for organizing sectioned data arrays
  • LlvmIrBufferManager.cs - Added documentation for buffer allocation and management functiona 8000 lity for structure members requiring preallocated buffers
  • LlvmIrStringGroup.cs - Added documentation for string grouping functionality that organizes related strings in IR output
  • LlvmIrTypeCache.cs - Added documentation for attribute caching system that improves performance by avoiding repeated reflection calls
  • LlvmIrModuleTarget.cs - Added comprehensive documentation for the abstract base class that defines target architecture implementations

Data Layout Classes

  • LlvmIrDataLayout.cs - Added extensive documentation for:
    • LlvmIrDataLayoutField base class and common functionality
    • LlvmIrDataLayoutPointerSize for pointer specifications
    • LlvmIrDataLayoutTypeAlignment base class for type alignment
    • LlvmIrDataLayoutIntegerAlignment, LlvmIrDataLayoutVectorAlignment, LlvmIrDataLayoutFloatAlignment for specific type alignments
    • LlvmIrDataLayoutAggregateObjectAlignment for structure/array alignment
    • LlvmIrDataLayoutFunctionPointerAlignment for function pointer specifications
    • Related enums and support functionality

Target Architecture Classes

  • LlvmIrModuleAArch64.cs - Added documentation for ARM 64-bit target implementation with AArch64-specific data layout and attributes
  • LlvmIrModuleX64.cs - Added documentation for x86-64 target implementation with System V ABI compliance details
  • LlvmIrModuleX86.cs - Added documentation for x86 32-bit target implementation with i686-specific settings

Support Classes

  • NativeAssemblerContextDataProvider.cs - Added documentation for context data provider base class that enables dynamic data generation
  • FunctionAttributes.cs - Added documentation for function attribute base class and core methods (partial coverage)

Documentation Quality

All added documentation includes:

  • Comprehensive class summaries explaining purpose and functionality
  • Complete parameter documentation with types and descriptions
  • Return value documentation where applicable
  • Exception documentation for error conditions
  • References to LLVM IR specification and relevant ABIs where appropriate
  • Architecture-specific implementation details for target classes

Code Integrity

  • All changes build successfully with zero compilation errors
  • Only pre-existing warnings remain (unrelated to these documentation changes)
  • Documentation follows existing patterns and conventions in the codebase
  • Maintains consistency with C# XML documentation standards
  • No functional code changes - purely additive documentation

Example

Before:

abstract class LlvmIrModuleTarget
{
    public abstract LlvmIrDataLayout DataLayout { get; }
    public abstract string Triple { get; }
    // ...
}

After:

/// <summary>
/// Abstract base class for LLVM IR module targets that define architecture-specific code generation settings.
/// Each target architecture implements this class to provide specific data layout, triple, and compilation settings.
/// </summary>
abstract class LlvmIrModuleTarget
{
    /// <summary>
    /// Gets the data layout specification for this target architecture.
    /// </summary>
    public abstract LlvmIrDataLayout DataLayout { get; }
    /// <summary>
    /// Gets the LLVM target triple for this architecture.
    /// </summary>
    public abstract string Triple { get; }
    // ...
}

The LLVM IR generator infrastructure now has well-documented core classes that developers can easily understand, maintain, and extend.

Fixes #10284.
