Help: How to define vector element type bool (v8i1) in C builtin function hello everyone,I have defined intrinsic function like this: def int_mips_add_32 : GCCBuiltin<"__builtin_dongxin_add_32">, Intrinsic<[llvm_v4i32_ty], [llvm_v4i32_ty, llvm_v4i32_ty,llvm_v8i1_ty]>; Then I write a test code : typedef int v4i32 __attribute__ ((vector_size(16))); typedef bool v8i1

I'm unable to figure out how IR attributes can be added via the C++ API. I need to create a function like this:     %1 = call i64 @abi_call_test_tuple_2p(%struct.abi_tuple_2p* byval align 8 %v) Where a structure is being passed by value. I need to add the `byval` attribute somewhere (I'm not clear if this is on the function arguments or the type). I'm also uncertain of why that

Hi Everyone, I'm happy to say that we just got approval to open source the new C front-end for LLVM we've been working on. The goal of this work is to provide a high quality front-end for LLVM that is built with the same principles as the rest of LLVM (it is built as a set of reusable libraries, integrates well with rest of the LLVM architecture, same license, etc). Among other

Ok, I've been looking at this for hours and can't figure it out. I know I'm missing something obvious. I've been spending the past few days beefing up the vector support in the C Backend. This should help us debug vector code that's miscompiled. But gcc doesn't like this fragment: ((double *)(&llvm_cbe_r1147))[0u] = (((llvm_cbe_r1146__BITCAST_TEMPORARY.Int64 =

Hi Devs, Consider below testcase. $cat test.cpp #include <vector> #include<type_traits> typedef int _int4 __attribute__((vector_size(16))); typedef union{ int data[4]; struct {int x, y, z, w;}; _int4 vec; } int4; typedef int4 int3; int main() { static_assert(std::alignment_of<int4>::value <= alignof(max_align_t), "over aligned!"); } $clang++ -m32 error:

Hi All, If the target supports quad-register R0:R1:R2:R3 (Rn is 32-bit register), is it possible mapping quad-register to v4i32 so that the following example work? typedef int v4si __attribute__ ((vector_size (16))); void foo(v4si i) { v4si j = i; } I don't know how to write CallingConv.td to represent the concept of occupying quad-register R0:R1:R2:R3 once seeing

While solving a clang build issue with netpbm10 on fink darwin11, I noticed that clang seems to provide poor error messages compared to llvm-gcc. For llvm-gcc, we get the very helpful warning... libpbm3.c: In function 'packBitsWithMmxSse': libpbm3.c:120: warning: specifying vector types with __attribute__ ((mode)) is deprecated libpbm3.c:120: warning: use __attribute__ ((vector_size))

Hi all, I have a backend for an in house architecture, and would like to start working on support for vector datatypes and intrinsics. As I starter I would like to have vector code scalarized, as is done, e.g., for the Mips backend. However, I cannot find a way to force the instruction selector or type legalizer to scalarize the vectors (i.e., vector types and vector ops). Can anyone help me out?

Hey guys, There seems to be an inconsistency between mask operand types for the AVX512 intrinsics. The mask instruction intrinsics expect a v16i1 for the mask operands: > def int_x86_kadd_v16i1 : GCCBuiltin<"__builtin_ia32_kaddw">, > Intrinsic<[llvm_v16i1_ty], [llvm_v16i1_ty, llvm_v16i1_ty], > [IntrNoMem]>; But other

The following code causes opt to not terminate! With TOT this morning, and of a week ago: clang foo.c and clang -O1 foo.c work fine. clang -O2 foo.c and clang -O3 foo.c do not terminate. (At least after 10 minutes) If I generate the bit code (clang-cc -emit-llvmbc) and then run: opt -O3 foo.bc it does not terminate. //foo.c int get_id(int); typedef short

I finally got all of the 3DNow! instruction intrinsics and builtins into LLVM and Clang, however, while testing them, I've noticed that they produce incorrect results. For example: typedef float V2f __attribute__((vector_size(8))); int main() { V2f dest, a = {1.0, 3.0}, b = {10.0, 3.5}; dest = __builtin_ia32_pfadd(a, b); printf("(%f, %f)\n", dest[0], dest[1]); } Should

The following code is causing me problems in the Sparc back-end and I believe it's related to a lot of issues that I have, so I'd love to work out what I need to do to resolve this. I'm currently not making much headway into it. I'm going to try to simplify this to the core problem I can see and hope I haven't missed anything relevant. The original code I have is as follows:

Hello, I started working on adding vector support for the SELECT and CMP instructions in the codegen (bugs: 3384, 1784, 2314).  Currently, the codegen scalarizes vector CMPs into multiple scalar CMPs.  It is easy to add similar scalarization support to the SELECT instruction.  However, using multiple scalar operations is slower than using vector operations. In LLVM, vector-compare operations

Rob, Ahmed, and Jingu, [I'm sorry if my point of view is too x86 centric.] >>the tricky part about fixing it is the need to settle on a memory layout for these vectors >> (packed vs byte per i1; packed would be compatible with AVX512, I think). I agree with Ahmed here, in principle. It's actually more than that, since vector compare in AVX2 and below produces the same

GCCBuiltin just gives it a name for clang to lookup. Generally they match up with builtins that gcc also implements, but that's not a requirement. If you add a builtin with the same name to the builtin file in clang's include/clang/Basic/Builtins*.def then they will find each other. You can also just add a builtin to clang's builtin file and catch it in clang's

Hi Bruce, Thanks for response. I also think it is not good way. Do you have the other ways to legalize it?

> 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
