Hi Eric, As we discussed on IRC, I don't think there is any reason for the implementation of these methods to check these

This patch supplies software IEEE floating point support. The comment from the patch reproduced below says all there is to say. This patch contains the prior "cleanup" patch; please don't apply that one. Please let me know of any bugs. It is tested reasonably well, but until I put together random tests it's hard to have 100% confidence. Neil. /* A self-contained host- and

Hi, I'm trying to separate the Support, System, ADT and Config header files into the support module, per previous plans. However, APFloat.h is not self-contained: APFloat.h:105:43: error: llvm/Bitcode/SerializationFwd.h: No such file or directory APFloat.h:106:37: error: llvm/CodeGen/ValueTypes.h: No such file or directory As you can see, APFloat.h depends on things that are not in the ADT,

I know someone completed this but I''m not sure the hows and whats of it. Can someone put up a doc or email about this?

Hi, I've been playing around with the APFloat class lately and I came across behavior I was not expecting based on reading the implementation comments and I'm wondering if it's a bug or intentional. The behavior concerns converting an APFloat to a string and back again. In the implementation of ``APFloat::toString(...)`` you can specify ``FormatPrecision`` as 0. The method comments

I have found some internal test failures due to the wrong constant folding on ppc_fp128. As documented in APFloat::PPCDoubleDouble, APFloat doesn't support PowerPC double-double correctly < https://github.com/llvm-mirror/llvm/blob/492acdd450bcdf9837494d6da029ed064f14fc33/lib/Support/APFloat.cpp#L74 >. To support this, we need to add a second tuple of (sign, exponent, significand) to

Hi! I wonder why APFloat::convertToDouble asserts if it is not an APFloat::IEEEdouble while the name "convertToDouble" suggests that it converts when it is not a double. -Jochen

The conversion is to (host) double, as the name implies. Among APFloat types, that is only implemented for APFloat::IEEEdouble.

Hi @llvm, I stumbled over a strange behavior if a float containing a NaN is printed (e.g. in the clang rewriter). The local template method "append" in APFloat.cpp deduces the size from the char array, which for "NaN" is 4 (including the trailing zero). If APFloat::toString is called with a SmallString and then SmallString::str() is called, it returns "NaN\0". I
