...s cannot be assembled later on (for instance with "llc") Yes, there are floating point values (such as NaNs) that cannot be expressed in decimal, and others that would require a prohibitively large number of digits. You don't want to do that. The code that writes out APFloats is in WriteConstantInt [sic] in VMCore/AsmWriter.cpp. It's not set up to do conversions separately from writing out, but you should be able to figure it out.

Hi guys Is some one able to explain me, why these errors emerge: gmake[2]: Entering directory `/usr/local/src/llvm/lib/VMCore' Compiling AsmWriter.cpp AsmWriter.cpp: In function `void WriteConstantInt(std::ostream&, const llvm::Constant*, bool, std::map<const llvm::Type*, std::string, std::less<const llvm::Type*>, std::allocator<std::pair<const llvm::Type* const, std::string> > >&, llvm::SlotCalculator*)': AsmWriter.cpp:255: error: ambiguous overload...

...Is it possible that when you configured/built gcc that it didn't find 64-bit integer support and disabled it or something? I really no nothing about internix so all I can do is speculate.
