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 v4i32. Any example that I can refer to? Thanks. Regards, chenwj -- Wei-Ren Chen (陳韋任) Homepage: https://people.cs.nct...

Hi Krzysztof, Thanks for response. The method is working almost of test cases which use load and store instructions connected with chain. There is other situation.

Hi Anton, I assume that's the same as the online demo's "Show LLVM C++ API code" option (http://llvm.org/demo/)? I've tried that with a structure containing four floating-point components but it also appears to add them individually using extract/insert. Maybe I have to try an array of floats...

Example below should be successfully compiled in any platform: typedef float v4sf __attribute__ ((vector_size(16))); void foo(v4sf *a) { (*a)[0] = 1; (*a)[3] = 2; } And we can get the IR mentioned before: %0 = load <4 x float>, <4 x float>* %a, align 16 %vecins1 = shufflevector <4 x float> <float 1.000000e+00, float undef, float undef, float 2.000000e+00&...

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 output (11, 6.5). However, it outputs different values depending on the optimization level. Generally one of them is correct, and the o...

...ucts aren't wrapped vectors; they wrap double or a pair of doubles, to get the size and alignment. Their only purpose is to be recognized by name by the front end and turned into a native register type. In gcc's arm_neon.h the user types aren't structs at all, they're defined using vector_size and the mangling is done as a special case. So I think there's no need to wrap these types in LLVM.
