James, Thanks for your response. I'm working in LLVM 2.7 (I know, it's old) and the default behavior is already promote. This means that for example a call to DAGTypeLegalizer::getTypeAction(v3i32) in my case and I presume in ARM NEON returns TypeWidenVector. From here legalization calls WidenVectorOperand() to process the STORE node and follows the call chain I have on my original email

Hi, * Is there a way to setup LLVM to automatically convert vec3s to vec4s? Yes, if you specify v3i16 and friends as "promote" instead of "legal", llvm will promote it to a v4i16. The ARM NEON backend does this already. I'm surprised you haven't got this happening already as you mention that LLVM widens your loads to 4-element vectors. (this should happen during

I still haven't received any feedback on me adding support for widening of stores. Is there interest?

Thanks. Yes. Your approach can identify: Glaxy ace S 5830 and S 5830 Glaxy ace But you can not identify using same program: Iphone 4S 16 G Iphone 4S 16G How should I solve both in same time. Kind regards,Tammy [[alternative HTML version deleted]]

Hi, May be this helps: m1<- as.matrix(read.table(text=" y1 g24 y1 0 1 g24 1 0 ",sep="",header=TRUE)) m2<-as.matrix(read.table(text="y1 c1 c2 l17 ?y1 0 1 1 1 ?c1 1 0 1 1 ?c2 1 1 0 1 ?l17 1 1 1 0",sep="",header=TRUE)) m3<- as.matrix(read.table(text="y1 h4??? s2???? s30 ?y1 0 1 1 1 ?h4 1 0 1 1 ?s2 1 1 0 1 ?s30 1 1 1

I would like to know whether there is a faster way to do the below operation (updating vec1). My objective is to update the elements of a vector (vec1), where a particular element i is dependent on the previous one. I need to do this on vectors that are 1 million or longer and need to repeat that process several hundred times. The for loop works but is slow. If there is a faster way, please let

Hi, There is now an RFC for a roadmap to native vector predication support in LLVM and a prototype implementation:   https://reviews.llvm.org/D57504 The prototype demonstrates: -  Predicated vector intrinsics with an explicit mask and vector length parameter on IR level. -  First-class predicated SDNodes on ISel level. Mask and vector length are value operands. -  An incremental strategy

Hi, I'm almost there with my Yasm printer, however, I've stumbled upon this. Using this: ; ModuleID = 'data.u' %window = type { %visobj, %vec2, %vec2, %vec2, %string, %color, i32, i32, %string, %string, %string, i1, i1, i1, i1, i1, i1, i32, i8* } %visobj = type { %object, i1, i1, i1, i1, %color, %vec4, %vec4, %vec4, %vec4, i32, %mat4, %mat4, %mat4, %mat4, %material*,

Hi all, I am trying to generate LLVM IR that calls an external C++ function returning a structure by copy: vec3 vec3::Cross(const vec3& iV) const; Here is the LLVM IR that I am generating for win32 ABI, which says that the first parameter should be a pointer to the return value: %vec3 = type <{ float, float, float }> define void @CPP_Return_Struct(%vec3* %v1, %vec3* %v2) inlinehint

OpenGL shading language (GLSL) is like a C subset language, but it contains some special features, ex: native vector type & swizzle. In GLSL, you can declare vector types: void main() { vec4 a; vec3 b; vec2 c; } You can access the element of vector by using .xyzw, it means the 1st, 2nd, 3rd, 4th element of the vector are x, y, z, w. Ex: void main() { float f; vec4 a = vec4(1.0,

Hi all, I’m not sure if this is the right list, so apologies if not. Doing some profiling I noticed some of my hand-tuned matrix multiply code with NEON intrinsics was much slower through a C++ template wrapper vs calling the intrinsics function directly. It turned out clang/LLVM was unable to eliminate a temporary even though the case seemed quite straightforward. Unfortunately any loads

Hi Guys, I have a taget instruction which take a vec4 and returns a vec4.( say instruction “vec4:$dst mod( vec4:$src)" ) And I want to use it to match i an ir instruction/intrinsic function( say " float:$dst llvm.irmod( vec4:$src)" which takes a vec4, output a float. I think the procedure is: when I see the intrinsic llvm.irmod, I need to call "extractlt(

Simple one, have read and googled, still no luck! I want to create several empty vectors all of the same length. I would like multiple empty vectors (vec1, vec2, vec3) and want to create them all in one line. I've tried vec1,vec2,vec3 <- vector(length=5) and c(vec1,vec2,vec3) <- vector(length=5) and several other attempts but nothing seems to work ... suggestions? Thanks Jim

Hi all, I’ve narrowed down a problem in my code to the following test case: - - - - typedef struct {float v[2];} vec2; typedef struct {float v[3];} vec3; vec2 getVec2(); vec3 getVec3() { vec2 myVec = getVec2(); vec3 res; res.v[0] = myVec.v[0]; res.v[1] = myVec.v[1]; res.v[2] = 1; return res; } - - - - Compiling this with any level of optimization for arm64 gives incorrect code,
