If it is possible to add the functionality of these functions to a library: Where is this library and how can these functions be added? Is it correct that entries in IntrinsicsPowerPC.td and PPCInstrInfo.td files have to be done to make these new intrinsics known? "migrate_begin" is an instruction with a variable argument list. Is there some special handling necessary to add variable argument functions? I would be thankful for any hints regarding this PowerPC backen...

This looks OK to check in, do you have write access?

...[llvm_v8f32_ty, llvm_v8f32_ty], [IntrNoMem]>; is turned into maxpd256 :: Ext.T (V4Double -> V4Double -> LLVM.CodeGenFunction r V4Double) maxpd256 = Ext.intrinsic ExtX86.avx "max.pd.256" This works for the flat structure of IntrinsicsX86.td, but e.g. IntrinsicsPowerPC.td uses tablegen classes. Now I wonder whether it is better to use tablegen to generate the Haskell code. The tblgen man page says, that tablegen emits C++. This would not be a big problem, since I could let it write C++ code that in turn writes Haskell code. Unfortunately the section "...

Hi: I want add new Instrinsic for my target. So I first do some test.

...better support for adding target-specific intrinsics like this, and lots of examples. Mainline CVS now supports all of the altivec intrinsics, and a big chunk of the SSE ones (still in progress). Adding support for Direct3D shaders should be straight-forward. Take a look at llvm/include/llvm/IntrinsicsPowerPC.td for examples. Adding an intrinsic to LLVM now is just a matter of adding it to the include/llvm/Intrinsics*.td file and adding a line to your code generator .td file. > DSP and other scientific programs do not permuate the vectors as > frequent as 3D programs do.

Hello. I'm writing a back end for my research SIMD processor that has an assembly language that is blocked structured, with one-level loops. An example program with my assembly language: REPEAT_X_TIMES(Param2) R0 = LS[offset_A]; END_REPEAT; The LLVM code somewhat equivalent to the above ASM program is: vector.body: %index = phi i64 [

Hi, I might just be doing something stupid, but when I do $ cmake -DCMAKE_INSTALL_PREFIX=/usr/local/llvm-2.8 -DCMAKE_BUILD_TYPE=Release .. $ sudo make install I don't get the expected headers in /usr/local/llvm-2.8/include/llvm It is simply an empty directory. What am I doing wrong? This is on Mac OS X, CMake 2.8+ Kind regards, Samuel
