similar to: Opportunity to split store of shuffled vector.

> I may be missing something obvious, but what is `vector` defined as here? Can you provide a buildable example? Sorry, I should provide a cross-platform version using vector extension of frontend :) `vector int` is a vector extension on PowerPC, which is enabled if you set target to PowerPC platforms. Example below should be successfully compiled in any platform: typedef float v4sf

Canonicalizing to a masked store intrinsic is possible, but we might have to expand back to the load/shuffle/store sequence for targets that don't support masked store. And then you'd likely have to do the store splitting that I think is being requested for the original pattern anyway. But I'd like to step back to the premise - "LLVM seems to always generate vector instructions

Hal, Yes, speed is an important factor of making dicision. Here I just put the numerator into estimation, so it won't add any more instructions. A simple benchmark below keeps the same running time between the demo and current master: ``` float fdiv(unsigned int a, unsigned int b) { return (float)a / (float)b; } float m; __attribute__((noinline)) void foo() { m = 0.0; } int main() {

Hi there, I notice that our current implementation of fast division transformation (turn `a / b` into `a * (1/b)`) is worse in precision compared with GCC. Like this case in ppc64le:         float fdiv(unsigned int a, unsigned int b) {                 return (float)a / (float)b;         } Result of Clang -Ofast is 41A00001 (in Hex), while GCC produces 41A00000 which is the same as no

I'm also a strong proponent of not requiring the wrapper. The linear history piece was important enough to make the cost worth it.  The extra branches piece really isn't.  If someone creates a branch that's not supposed to exist, we just delete it. No big deal.  It will happen, but the cost is so low I don't worry about it. There's a bunch of things in our developer policy

Indeed. But the problem here is that Dinar is trying to keep information after a load/store is removed by instcombine For example: v4sf v = {p[0], p[1], p[2], p[3]}; v4sf v2 = shuffle(v, 0, 0, 2, 2); Some pass comes in and removes the p[3] and p[1]. Now you have smaller code, but lost the ability to use a vector load for all those values + shuffle. The code got scalarized because we lost the

Hi all: A short question: For example, a=[3,4,6,2,3], obviously the 3rd entry of the array has the maxium value, what I want is index of the maxium value: 3. is there a neat expression to get this index? Thank you! Best, Feng [[alternative HTML version deleted]]

Hi, there: As you all know, correlation is not a very robust procedure. Sometimes correlation could be driven by a few outliers. There are a few ways to improve the robustness of correlation (pearson correlation), either by outlier removal procedure, or resampling technique. I am wondering if there is any R package or R code that have incorporated outlier removal or resampling procedure in

I am not sure whether there is a bug. When I tested the example given for "glht" in the help, I entered the following error: Running commands: amod <- aov(minutes ~ blanket, data = recovery) rht <- glht(amod, linfct = mcp(blanket = "Dunnett"), alternative = "less") Errors are: Error in try(coef.(model)) : could not find function

Dear all, I'd like to change a point pattern to a grid of cells and use one of the variables as the output. e.g. The point pattern is of a window of (500*500) and several features such as pH, SoilType etc. I like to divide it into a grid with cell size 5*5, and use the mean of the point values falling inside the cell as the output. Is there any package in R working with this? Thanks in

Hi, While working on PR21780, I used "dereferenceable_or_null" metadata and I realized now that it is not correct for my solution to use this metadata type since it might point to an address that it is not dereferenceable but null. I think that we need another new metadata type, something like "dereferenceable" with that we could annotate any load (not just pointer type like

Hi all, The firmware I used is pa168s_iax2_us_151011.bin. My problem is the handset dial before I finished key in all the numbers, no matter how fast I managed to press the keys. It appeared it always dialed immediately, for example "011862", when I actually ment to dial 0118620xxxxxxxx. Thus left the remaining numbers "0xxxxxxxx" unsent. The handset had its dial plan

Hi, Following code snippet, running as non-root user, will throw up a 'Permission denied' RuntimeError. Could someone kindly guide me the correct way to handle LVM disk as non-root user? Cause as http://libguestfs.org homepage claims, "libguestfs doesn't need root permissions." A little confused somehow. import guestfs g = guestfs.GuestFS()
