similar to: How to play Floating point numbers?

Hi all: I need an instruction that can convert decimal values into floating point numbers. i.e. say I have a decimal number 1110794174 (== 42355FBE in hex ) and (== 45.3435 as a float) essentially the mantissa and exponent representation needs to be used. Is there any way of doing this in llvm? Thanks and Regards -- -- Aparna Kotha Graduate Student Electrical and Computer Engineering

I'm saying at the IR level, not the C level. IR makes certain assumptions about the representation of floating point numbers. Nothing to do with C, I only used it as an example. - CL > On Apr 14, 2016, at 4:49 PM, Martin J.

My understanding is that this checks whether the bit width of the integer *type* fits in the bit width of the mantissa, not the bit width of the integer value. - CL > On Apr 14, 2016, at 6:02 PM, escha at apple.com wrote: > > We already do this to some extent; see this code in InstCombineCasts: > > // fpto{s/u}i({u/s}itofp(X)) --> X or zext(X) or sext(X) or trunc(X) > //

Re-ordered the reply, since it is easier to follow the thread when the replies are at the bottom.

Hi, I am not sure if this is just me using R (R-2.3.1 and R-2.4.0) in the wrong way or if there is a more serious bug. I was having problems getting some calculations to add up so I ran the following tests: > (2.34567 - 2.00000) == 0.34567 <------- should be true [1] FALSE > (2.23-2.00) == 0.23 <------- should be true [1] FALSE > 4-2==2 [1] TRUE > (4-2)==2 [1] TRUE >

Hi all, I need to convert a floating point value from Microsoft Basic format to IEEE format. There's a simple way to achieve this in R or I have to write my own function? (e.g. convert the C code below) thanks t #include <string.h> /* for strncpy */ int _fmsbintoieee(float *src4, float *dest4) { unsigned char *msbin = (unsigned char *)src4; unsigned char *ieee

Hi all, I'd like to make use of some specific x86 Streaming SIMD Extension instructions, but I don't know where to start. For instance the 'rcpps' instructions computes a low precision but fast reciprocal. I've noticed that LLVM supports intrinsics, but I couldn't find any information on how to use them. I've tried digging through the LLVM-GCC code but it's just

Hi Jean-Marc, As I told you, bank is a reserved keyword in Analog Devices compiler for Blackfin architecture. So we need to change the variables named bank to something else. Here's a patch that changes bank to bnk in the 3 concerned files. (Hope the format is OK) About my previous problems with the Blackfin: -> strange block repetition that could be cancelled by the AEC I was busy

I'm running into some pretty bad performance in llc.exe when compiling some large neural networks into code that contains some very large llvm::ConstantDataArrays, some are { size=102,760,448 }. There's a small about of actual code for processing the network, but the assembly is mostly global data. I'm finding that llc.exe memory spikes up around 30 gigabytes and the job takes 20-30

Hi, I'm seeing something that may be a bug in R's standalone math library, which is packaged by Debian as r-mathlib. I reported it to the Debian BTS as http://bugs.debian.org/657573 I'm using Debian squeeze, and the code was tested with r-mathlib 2.11.1-6 (default on stable) and 2.14.1-1 (from testing/unstable). I summarize this report below. The following code with the R math

Dear rsync people, I have just started using rsync for backups. I have had a couple of issues. Note I'm trying to use rsync as user using ssh between two machines both running Debian GNU/Linux potato (2.2r3). The local machine is currently running 2.4.6-1 and the remote 2.3.2-1.2. 1) When I run rsync with the vv option, stuff scrolls of my screen faster than I can read it. I was wondering if
