[LLVMdev] IEEE 754-2008 | ISO/IEC TR 18037

LLVM does not support IEEE decimal-floating point.

If by “fixed point arithmetic” you are asking about associating a scale factor with a variable/value, and doing the correct scaling for arbitrary arithmetic… LLVM doesn’t do that either.  It’s a rare IR that even has the concept.  The OpenVMS GEM compilers supported it (along with other special features for COBOL), but I’m not aware of any others.

Does LLVM support decimal precision numbers supported? Also does it have Fixed point arithmetic?
