These functions are "shared" between integer and floating-point types, hence the directory name. They are used in several CLC internal functions such as __clc_ldexp. Note that clspv and spirv targets don't want to define these functions, so pre-processor macros replace calls to __clc_min with regular min, for example. This means they can use as much of the generic CLC source files as possible, but where CLC functions would usually call out to an external __clc_min symbol, they call out to an external min symbol. Then they opt out of defining __clc_min itself in their CLC builtins library. Preprocessor definitions for these targets have also been changed somewhat: what used to be CLC_SPIRV (the 32-bit target) is now CLC_SPIRV32, and CLC_SPIRV now represents either CLC_SPIRV32 or CLC_SPIRV64. Same goes for CLC_CLSPV. There are no differences (measured with llvm-diff) in any of the final builtins libraries for nvptx, amdgpu, or clspv. Neither are there differences in the SPIR-V targets' LLVM IR before it's actually lowered to SPIR-V.
