Description
Once Opaque Pointers in QIR is resolved, the deprecated calls need to be replaced with the new versions:
| Old Name | New Name |
|---|---|
| LLVMBuildLoad | LLVMBuildLoad2 |
| LLVMBuildCall | LLVMBuildCall2 |
| LLVMBuildInvoke | LLVMBuildInvoke2 |
| LLVMBuildGEP | LLVMBuildGEP2 |
| LLVMBuildInBoundsGEP | LLVMBuildInBoundsGEP2 |
| LLVMBuildStructGEP | LLVMBuildStructGEP2 |
| LLVMBuildPtrDiff | LLVMBuildPtrDiff2 |
| LLVMConstGEP | LLVMConstGEP2 |
| LLVMConstInBoundsGEP | LLVMConstInBoundsGEP2 |
| LLVMAddAlias | LLVMAddAlias2 |
In preparation for this, we need to move PyQIR to LLVM 16 which should allow working with modules that can use both typed and opaque pointers. This should give us a working base from which others can migrate their tooling to support opaque pointers. We will need to design an API that allows us to turn on/off opaque pointers and use the appropriate LLVM calls depending on which API is being used.
