Introduction: We would like to add new keyword to 'sdiv'\'udiv' instructions i.e. 'no-overflow'. This is the updated solution devised in the discussion: http://lists.llvm.org/pipermail/llvm-dev/2017-October/118257.html The proposed keywords: "nof" stands for 'no-overflow' Syntax: <result> = sdiv nof <ty> <op1>,

Introduction ========== We would like to add support for masked vector signed/unsigned integer division and remainder in the LLVM IR by introducing new target-independent intrinsics. This follows similar work which was done already for masked vector loads and stores - http://lists.llvm.org/pipermail/llvm-dev/2014-October/078059.html. Another relevant reference is the masked scatter/gather

I have a nice hierarchical table structure like this: divisions has_many groups groups belongs_to division has_many subgroups subgroups belongs_to group has_many units units belongs_to subgroup I have a report which is based on units, but i want to be able to filter the units by which subgroup, or which group, or which division. I also want to sort them by division.name,then group.name,

It seems division with numbers bigger than 10 000 000 doesn't work 20000000/21 [1] 952381 > 55555555/23 [1] 2415459 Thank you

lets say i have the following SQL in my database editor : When i paste it into rad rails i have to add quotes and the ''+'' symbol to the end of each line. It is very tedious. What is the best method? select timesheets.employee, sum(items.hours) as hours, sum(items.hours*timesheets.cost) as cost, sum(items.hours*timesheets.charge*decode(activities.chargetype,0,1,0)) as charge,

Andy - If you're not already following this closely, please start. We've gotten into fairly fundamental questions of what a patchpoint does. Filip, I think you've hit the nail on the head. What I'm thinking of as being patchpoints are not what you think they are. Part of that is that I've got a local change which adds a very similar construction (called

The file src/share/replaygain_synthesis/include/private/fast_float_math_hack.h redefines 'tanh' as 'tanhf'. This file is intended for Intel Compiler only, but it includes outdated mathf.h and doesn't work with current versions of ICC. The fixes are trivial though, and I compiled 2 versions of flac.exe: with this 'hack' turned off an on. The difference in decoding speed

Hello everyone, I am learning R since recently, and as a small exercise I wanted to write a recursive mergesort. I was extremely surprised to discover that my sorting, although operational, is deeply inefficient in time. Here is my code : > merge <- function(x,y){ > if (is.na(x[1])) return(y) > else if (is.na(y[1])) return(x) > else if (x[1]<y[1])

I'm still not convinced, but am not going to actively oppose it either. I'm leery of designing a solution with major assumptions we don't have data to backup. I worry your assumptions about

...n the problem with my development builds, for which I use a faster but less efficient compression for the included squashfs, so the images end up being around 1.2GiB in size. I haven't got a good sample size, but I'd say there seemed to be a 50% chance of isohybrid making the image size not divisible by 2048. If it's of any help, here are some examples of development builds's sizes before and after isohybrid post-processing: # Example 1 Before: 1263595520 After: 1266693120 which is divisible neither by 1024^2 nor 2048 # Example 2 Before: 1309853696 After: 1316044800 which is divisi...

Hi Team, I observer that division of __int128 bit is very heavy operation. It internally call a routine '__udivti3', which internally call ' __udivmodti4'. Due to it the overall performance is much much slower (almost 15 time slower than if I do it via a combination of 64-bit or microsoft '_udiv128'). Also what to know if I can directly call below routine directly from

Each Timesheet has an employee. An employee has a division and a location. I want to find all the timesheets with a status of 2. I then iterate over the timesheet collection and print the timesheet name, employee name, employee divison name, and employee location name. Like so: for t in Timesheet.find(:all,:conditions=>"status=2",:include=>:employee) puts timesheet.date

Dear R gurus. Is there an R function equivalent to octaves / (Right division) withouth forming the inverse of Y' using solve ? [snip - from octave docu] Right division. This is conceptually equivalent to the expression (inverse (y') * x')' but it is computed without forming the inverse of Y'. If the system is not square, or if the coefficient matrix

I was looking through the InstCombine pass, and I was wondering why signed division is not considered a valid operation to combine in the canEvaluateTruncated function. This means, given the following code: %conv = sext i16 %0 to i32 %conv1 = sext i16 %1 to i32 %div = sdiv i32 %conv, %conv1 %conv2 = trunc i32 %div to i16 * Assume %0 and %1 are registers created from simple 16-bit loads.
