...illObjects - A set of frame indices represnting spill slots. typo represnting. Why does SpillObjects need to be a DenseSet? It seems that it is created in order. I think it can just be a vector which is looked up with a binary search. Instead of making CreateStackObject take a "bool isSpill", how about adding a new "CreateSpillStackObject"? That seems much nicer in the code than having: CreateStackObject(16, 16, /*isSpill*/false); everywhere. The number of places that create spill slots is pretty small compared to the number of "/*isSpill*/false"....

Attached is a patch to print asm comments for spill information. We've discussed the mechanisms before but I wanted to run the patch by everyone before I start to commit pieces. -Dave -------------- next part -------------- A non-text attachment was scrubbed...

Hello, I'm getting the "LLVM ERROR: ran out of registers during register allocation" error message for an out of tree target I'm developing. This is happening for the following piece of C code: struct ss { int a; int b; int c; }; void loop(struct ss *x, struct ss **y, int z) { int i; for (i=0; i<z; ++i) { x->c += y[i]->b; } } The problem relies in
