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

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.

There are certainly enough people making commits that work with VS2015 but not VS2013 that the "would it be useful" question is pretty well answered. I've already brought up the idea on my team, as it's obviously coming and we need time to coordinate with internal consumers of the toolchain. --paulr From: llvm-dev [mailto:llvm-dev-bounces at lists.llvm.org] On Behalf Of Zachary

FWIW, no objections from me, after all I proposed this 3 months ago :) Probably Aaron Ballman should comment though since the primary objection last time was his.

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,

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, 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

There are not that many people making commits to working around MSVC 2013 as I think are claimed (there are certainly a lot of commits for working around MSVC in general, however). A quick search through the code base shows there are 8 instances where we've worked around MSVC 2013 issues (there may be more that someone worked around in an ad hoc manner and did not mark). We definitely had *a

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

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:
