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

Hello. When running clang in Debug mode, I am getting an assertion failure when parsing the following line: float ko = 0x1.1p0; Apparently, the recent changes in the use of StringRef haven't been propagated to all places. Please find attached the trivial patch. Cheers, Enea Zaffanella. -------------- next part -------------- An embedded and charset-unspecified text was scrubbed... Name:

I'm breaking this out from LLVM asserts thread. Here are all the assertions in APInt I consider should be recoverable: APInt::APInt: bitwidth too small Null pointer detected!

Yeah. That code has been there since r91421 and wouldn't have failed recently otherwise. Did something change on the host? -eric On Sep 20, 2011, at 11:27 AM, Jim Grosbach wrote: > The host c++ standard library is missing <utility>, it appears. > > > On Sep 20, 2011, at 11:22 AM, Galina Kistanova wrote: > >> Please use the correct link : >>

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 All, APFloat::fusedMultiplyAdd currently computes the wrong signed zero when small negative results are truncated back to zero in standard precision. The following snippet handles the signedness in fusedMultiplyAdd: /* If two numbers add (exactly) to zero, IEEE 754 decrees it is a positive zero unless rounding to minus infinity, except that adding two like-signed zeroes gives that

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

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

Hi Mehdi, Thanks for the feedback. I think the comment is fine - the problem is just that the original conditional didn't exactly match it. With the addition of the underflow check I believe the condition now matches the comment: The sign is only tweaked if the result of the addition is exactly zero, rather than a small result that truncates to zero.
