This makes all allocation of memory for the interpreter which are long-lived be allocated in the one big allocation. This should fix any issues where we have memory leaking from collectible assemblies.

…aBuilder
Remove the unused InterpReloc struct, m_relocs member, and AddReloc
method from InterpMethodDataBuilder. The relocation application loop
in Finalize is also removed since there are no relocs to apply.
The MemPoolAllocator constructor parameter is removed since it was
only needed for the TArray<InterpReloc> member, and the datastructs.h
include is dropped as TArray is no longer used in the header.

Pull request overview

This PR refactors CoreCLR interpreter method compilation to place long-lived per-method data (bytecode header + bytecodes + method metadata + related structures) into a single allocation obtained via the JIT allocMem interface, with the goal of preventing leaks for collectible assemblies.

Changes:

  • Introduces InterpMethodDataBuilder to size/lay out a unified method-data allocation.
  • Switches InterpCompiler::CompileMethod to return bool and adds GetTotalAllocationSize/FinalizeMethodData to drive unified allocation and finalization.
  • Adds a new interpreter memory kind (IMK_MethodData) and updates allocator plumbing (MemPoolAllocator) and build inputs.

This makes all allocation of memory for the interpreter which are long-lived be allocated in the one big allocation. This should fix any issues where we have memory leaking from collectible assemblies.

Remove the unused InterpReloc struct, m_relocs member, and AddReloc
method from InterpMethodDataBuilder. The relocation application loop
in Finalize is also removed since there are no relocs to apply.
The MemPoolAllocator constructor parameter is removed since it was
only needed for the TArray<InterpReloc> member, and the datastructs.h
include is dropped as TArray is no longer used in the header.

Pull request overview

This PR refactors CoreCLR interpreter method compilation to place long-lived per-method data (bytecode header + bytecodes + method metadata + related structures) into a single allocation obtained via the JIT allocMem interface, with the goal of preventing leaks for collectible assemblies.

Changes:

  • Introduces InterpMethodDataBuilder to size/lay out a unified method-data allocation.
  • Switches InterpCompiler::CompileMethod to return bool and adds GetTotalAllocationSize/FinalizeMethodData to drive unified allocation and finalization.
  • Adds a new interpreter memory kind (IMK_MethodData) and updates allocator plumbing (MemPoolAllocator) and build inputs.

This makes all allocation of memory for the interpreter which are long-lived be allocated in the one big allocation. This should fix any issues where we have memory leaking from collectible assemblies.

…aBuilder
Remove the unused InterpReloc struct, m_relocs member, and AddReloc
method from InterpMethodDataBuilder. The relocation application loop
in Finalize is also removed since there are no relocs to apply.
The MemPoolAllocator constructor parameter is removed since it was
only needed for the TArray<InterpReloc> member, and the datastructs.h
include is dropped as TArray is no longer used in the header.

Pull request overview

This PR refactors CoreCLR interpreter method compilation to place long-lived per-method data (bytecode header + bytecodes + method metadata + related structures) into a single allocation obtained via the JIT allocMem interface, with the goal of preventing leaks for collectible assemblies.

Changes:

  • Introduces InterpMethodDataBuilder to size/lay out a unified method-data allocation.
  • Switches InterpCompiler::CompileMethod to return bool and adds GetTotalAllocationSize/FinalizeMethodData to drive unified allocation and finalization.
  • Adds a new interpreter memory kind (IMK_MethodData) and updates allocator plumbing (MemPoolAllocator) and build inputs.
