[LLVMdev] Reg2mem: Identifying introduced memory locations (also, what happens to the phi nodes)
Hi.
Im exploring `opt -reg2mem` output for a simple C program (actually,
that is this snippet:
http://rosettacode.org/wiki/Dining_philosophers#C - compiled with
clang -O1) and got two questions regarding this pass.

pass, and which memory locations were present in the original program?
After a brief diffing of .ll files, I'd suppose that introduced
"alloca"...
