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 all, can I access the numeric limits of the llvm types, e.g. HalfTy, FloatTy, DoubleTy, etc. in a fashion like the std numeric_limits tool? std::numeric_limits<half>::min() std::numeric_limits<half>::max() In c++API, I want to initialize values and need to know the correct range for the llvm types.... Thx Alex

Good day, LLVMers! We are starting on our third (and hopefully last) round of testing for LLVM 3.0. Please visit: http://llvm.org/pre-releases/3.0/rc3/ for the sources. There are also binaries for Darwin up there, with more to come during the week. Please build this release candidate, test it out on your projects, and let us know if you find any regressions from the 2.9 release. Please keep

I've got comments on the code change. The test cases look ok, but I haven't fully checked the math on the half-values. I checked with reference to trunk top-of-tree at revision 156617. I have not compiled the code. lib/AsmParser/LLLexer.cpp Adds support to parse format: 0xH<hexdigits> Tha 0xH format should be described in LangRef.html alongside 0xK<hex> and

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

Hello, llvmdev! I'm using LLVM on OpenBSD. This project proactively advocates usage of 'secure' C apis, especially related to memory bounds checking. Thus using functions like sprintf/strcpy/etc usually spits out a linker warning in base toolchain like this one: /home/proger/dev/llvm/Debug+Asserts/lib/libclangFrontend.a(DocumentXML.o) (.text+0xc65): In function

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
