Move to cmake/options.cmake.

@2over12 thoughts on removing nvptx and wasm from cxx-common?

Is there a way to make this specific to a target?

Alternatively, can this be turned into a PR to sleigh?

I think there should be a $<INSTALL_INTERFACE:${CMAKE_INSTALL_INCLUDEDIR}>, given that GNUInstallDirs is included.

The $<INSTALL_INTERFACE> with the GNUInstallDirs is already implicitly adding when exporting the target, so you should be able to actually remove it from the target.

Why FoldBitCast in a ZExt case?

Why deleted? Does LLVM no longer support these in constant expressions?

Yeah, they are in the process of gutting the ConstantExpr functionality, this is what's left in LLVM 19: https://github.com/mrexodia/llvm-headers/blob/17bb678153ba1c5c87bb17f6cd36894cb88d5c0d/19.x/llvm/IR/Constants.h#L1101-L1159

Thinking about it, probably a bunch of cases could be merged as follows:
case llvm::Instruction::Foo:
...
case llvm::Instruction::Bar: {
if (auto op = llvm::dyn_cast<llvm::BinaryOperator>(...)) {
... = ConstantFoldBinaryOpOperands(

Probably should drop support for 15 and 16, especially if 17-related changes were made (e.g. dropping constant expression stuff).
