not safe to return vector pointer
Hello All,
I recently upgraded from R-1.1.1 to R-1.2.2.
I have an R function that uses .Call() to
return a list from C code. The C code
has the form:
SEXP function(SEXP var)
{
SEXP rlist ;
PROTECT(rlist = NEW_LIST(3)) ;
VECTOR_PTR(rlist)[0] = NEW_INTEGER(1) ;
VECTOR_PTR(rlist)[1] = NEW_STRING(1) ;
...
UNPROTECT(1) ;
return(rlist) ;
}
When I try to .Call("function",...) from R I get
the following error message:
Error: not safe to return vector pointer
Why is it no longer safe to return a vector poi...

[LLVMdev] parallel loop metadata simplification
Hi,
I've been working on clang codegen for #pragma ivdep and creating the llvm.mem.parallel_loop_access metadata seems quite difficult. The main problem is that there are so many places where loads and stores are created and all of them need to be changed when emitting a parallel loop. Note that creating llvm.loop.parallel is not a problem.
One option is to modify IRBuilder to enable
