List of C intrinsics that are lowered to llvm.x86.* LLVM IR intrinsics
This bug is for tracking the effort of lowering all X86 C intrinsics to
target-independent LLVM IR, for all cases that it can be done reasonably.
The attached CSV file was created by Ayman Musa. It should contain a list of
all intrinsics which are lowered to calls to llvm.x86.* intrinsics.
The list was created by parsing the Clang tests.
All intrinsics that cannot be lowered to a reasonable LLVM-IR code such that
the semantics of the original function are easy to identify at Isel, are marked
as so.
Of the 3142 intrinsics functions that appear in the CSV:
- 139 were identified as *can* be lowered to target-independent IR
- 55 were identified as *cannot* be lowered to target-independent IR
- 2948 are TBD. (Yes, lots of more work ahead of us).</pre>
