tree-flow.h (register_jump_thread): Pass vector of edges instead of each important edge.
* tree-flow.h (register_jump_thread): Pass vector of edges
instead of each important edge.
* tree-ssa-threadedge.c (thread_across_edge): Build the jump
thread path into a vector and pass that to register_jump_thread.
* tree-ssa-threadupdate.c (register_jump_thread): Conver the
passed in edge vector to the current 3-edge form.
