Hi all, I'm very new to R and I'm trying to construct a threaded binary tree using recursive functions. I'm very confused was wondering if anyone had any R sample code they would share. I've come across a lot of C++ code(nothing in R) and this is not helping. best, MK -- View this message in context:

...iven C like void atomic_foo(int *addr) { int oldval = *addr; do { newval = foo(oldval); } while (__c11_compare_exchange_weak(addr, &oldval, newval)); The cmpxchg representation would be something like: define void @atomic_foo(int *addr) { entry: %firstval = load i32* %addr br label %loop loop: %oldval = phi i32 [%firstval, %entry], [%wrongval, %loop] %newval = call i32 @foo(i32 %oldval) %res = cmpxchg weak i32* %addr, i32 %oldval, i32 %newval %wrongval = extractvalue { i32, i1 } %res, 0 %success =...

Perhaps I missed something but I don''t see an easy way to do this ? Basically just wanna hold some ui state in a cookie. Did I miss something obvious ?

Hi, I've been looking at improving atomicrmw & cmpxchg code more, particularly on architectures using the load-linked/store-conditional model. The summary is that current expansion for cmpxchg seems to happen too late for LLVM to make meaningful use of the opportunities it provides. I'd like to move it earlier and express it in terms of a first-class pair of "load linked"
