Summary: Returns the size of a list. I have found this to be rather useful in some development for the AMDGPU backend where we could simplify our .td files by concatenating list<LLVMType> for complex intrinsics. Doing so requires us to compute the position argument for LLVMMatchType. Basically, the usage is in a pattern that looks somewhat like this: list<LLVMType> argtypes = !listconcat(base, [llvm_any_ty, LLVMMatchType<!size(base)>]); Change-Id: I360a0b000fd488d18bea412228230fd93722bd2c Reviewers: arsenm, craig.topper, tra, MartinO Subscribers: wdng, llvm-commits, tpr Differential Revision: https://reviews.llvm.org/D43553 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@325883 91177308-0d34-0410-b5e6-96231b3b80d8
