similar to: RFC: Constant folding math functions for long double

Hi Joerg, > IMO if constant folding of transcendental functions makes a significant difference for your program, you likely are doing something strange already. Alas it's not as simple as that. Currently, if you declare: std::uniform_real_distribution<float> x; LLVM emits two calls to logl() with constant arguments, a fdiv and a fptoui. Libc++'s implementation is consumed and

Hi, If you're interested, include/bits/random.tcc:3312 (std::generate_canonical()). I wish I could just point people at libc++, but that's outside of my control. As for fixing the library, that horse bolted some time ago.

Hi Neil, I admit that at this point I haven't considered the implications of the license MPFR is under, and at the moment I'm sticking my head in the sand until and unless we want to go down this path. My expectation is that we would use their exposed API - so we'd #include <mpfr.h> and use functions from there, linking against -lmpfr and -lgmp. I admit that this option would

Hello, I am trying to cross-compile libc++ from my x86_64 linux system to armv7hf. We have our own gcc compiler that we build with crosstools-ng (based on gcc 6.3.0) and I set my environment like this: CC=armv7a-plex-linux-gnueabihf-gcc CXX=armv7a-plex-linux-gnueabihf-g++ CFLAGS=-fPIC -DPIC -mfloat-abi=hard -march=armv7-a -Os -mfpu=vfpv3-d16 --sysroot=<path> CXXFLAGS=-fPIC -DPIC

I hear what you are saying about the accuracy. The problem, from my perspective, is trying to explain to users what they are going to get.

At first glance, it looks like long double functions (such as fabsl and friends) are missing from your sysroot's <math.h>. Does your target support long double at all? -Dimitry > On 6 Feb 2018, at 09:51, Tobias Hieta via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > Hello, > > I am trying to cross-compile libc++ from my x86_64 linux system to armv7hf.

Hello Dimitry and thanks for your answer. I am pretty sure it does indeed support long double. It's configured with vfpv3-d16 - but I noticed that c++config.h in gcc has _GLIBCXX__HAS_FABSL and friends are undefined. I think I need to look deeper at the configuration of our toolchain. long double support is required in libc++ then I gather? -- Tobias On Tue, Feb 6, 2018 at 11:47 AM,

Hi R-helpers, I need to read some file with different lines (I don't know the number of lines to skip) and I would like to find a way to start reading the data.frame from the word "source". ex: djhsafk asdfhkjash shdfjkash asfhjkash #those lines contain numbers and words, I want to skip then but they have different sizes asdfhjkash asdfhjksa source tret 2 res 3 Can

I need a little piece of advice concerning passing data frames into the functions. As I do a lot of similar fits at a time, I'd like to write a small function doing the fits for all relevant variables automatically. However, I usually get error messages of the following kind: (I present here a part of a test code). ##################################################### # Data set:

Hi, I have generated a profile likelihood for a parameter (x) and am trying to get 95% confidence limits by calculating the two points where the log likelihood (LogL) is 2 units less than the maximum LogL. I would like to do this by linear interpolation and so I have been trying to use the function approxfun which allows me to get a function to calculate LogL for any value of x within

I believe that once you have roaming profiles configured, all you need to do to configure folder redirection is set some registry keys. I'd like to turn that job over to our Windows sys admin. Can someone provide me with their favorite documentation for configuring folder redirection? Keep in mind I am passing this link along to a Windows sys admin. Our backend is samba 3.6.3 if it

Hello All, the patch below adds a target lowering hook to state that the target supports (or not) floating point exception behavior. The patch is small and contains one possible use for the hook (folding potentially exception raising fp operations). Any comments? Thanks Pedro -------------- next part -------------- An embedded and charset-unspecified text was scrubbed... Name: opensource1.txt

I assume you meant to ask for ports that *don’t* support floating point exceptions. To my knowledge, neither R600 nor NVPTX support floating point exceptions. —Owen > On Aug 8, 2014, at 2:41 PM, Eric Christopher <echristo at gmail.com> wrote: > > There's a lot of cut and paste in those routines.
