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(

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]]

...> GenWidenVectorStores() -> FindMemType(). I've made a very small modification to enable support for widening stores to a larger type. Before spending more time on working on a generic solution I have a couple of questions: * Is there a way to setup LLVM to automatically convert vec3s to vec4s? * Is there interest in adding support for widened vector stores to a larger type?

I'm trying to debug a problem with our custom backend with using a tiered register allocation setup. Just a little background. My target uses vec4 32bit registers and I want to have three levels of registers setup. Each vec4 register can have two sub-regs of size vec2 32bit, and each sub-reg, has its own two sub-regs of 32bit each. So it looks like this, xyzw -> {xy, zw} -> {x, y, z,

Thanks, I think it can solve my problem. But please allow me to explain the hardware in detail. Hope there is more elegant way to solve it. The hardware is a "stream processor". That is, It processes samples one by one. Each sample is associated with several 128-bit four-element vector registers, namely: * input registers - the attributes of the sample, the values of the registers

Hello guys, Thanks for your help when you are busing. I am working on an open source project. It supports shader language and I want JIT feature, so LLVM is used. But now I find the ABI & Calling Convention did not co-work with MSVC. For example, following code I have: struct float4 { float x, y, z, w; }; struct float4x4 { float4 x, y, z, w; }; float4 fetch_vs( float4x4* mat

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,

Yes, it's a constant register. Because the instruction cannot contain an immediate value, a constant value may be stored in a constant register, and it's defined _before_ the program starts by

Hey, as some of you may know we're in process of experimenting with LLVM in Gallium3D (Mesa's new driver model), where LLVM would be used both in the software only (by just JIT executing shaders) and hardware (drivers will implement LLVM code-generators) cases. While the software only case is pretty straight forward I just realized I missed something in my initial evaluation. That
