...ve to give you a sad answer that: target specific intrinsic is not work. I tried target specific intrinsic. However, LLVM isolates backend and frontend, and there's no way to pass language level type information to backend code. Think about a program like this: struct strA { int a; } struct strB { int b; } int func() { struct strA a; struct strB b; a.a = 1; b.b = 2; bpf_output(gettype(a), &a); bpf_output(gettype(b), &b); return 0; } BPF backend can't (and needn't) tell the difference between local variables a and b in theory. In LLVM implementation, i...

If I change it to MVT::i32 the code works but instead of a single byte store (STRB) I get a word store (STR). How can I force the width of the store?

Hello community, I faced with bug in multithread environment in objective C code which using dispatch_async and block, __sync_add_and_fetch increments global variable. But in case of many..many threads> 5, after every __sync_add_and_fetch got damaged ... int32_t count = 0; ... int main(int argc, char *argv[]) {    for (i = 1; i < 32; ++i) {      ...         char* name;        

Hello, I'm just start learning R/S-Plus, so I think this 2 doubts is going to be too easy for you... 1) I couldn't discover what is the command for a concatenation of 2 variable strings. 2) For example, if I have three variable strings, and each one has the name of a variable in a data matrix: a<-V1 b<-V2 c<-V3 , is it possible to construct a command like this:
