proc.c (rb_proc_alloc): inline and move to vm.c
* proc.c (rb_proc_alloc): inline and move to vm.c (rb_proc_wrap): new wrapper function used by rb_proc_alloc (proc_dup): simplify alloc + copy + wrap operation [ruby-core:64994] * vm.c (rb_proc_alloc): new inline function (rb_vm_make_proc): call rb_proc_alloc * vm_core.h: remove rb_proc_alloc, add rb_proc_wrap * benchmark/bm_vm2_newlambda.rb: short test to show difference First we allocate and populate an rb_proc_t struct inline to avoid unnecessary zeroing of the large struct. Inlining speeds up callers as this takes many parameters to ensure correctness. We then call the new rb_proc_wrap function to create the object. rb_proc_wrap - wraps a rb_proc_t pointer as a Ruby object, but we only use it inside rb_proc_alloc. We must call this before the compiler may clobber VALUE parameters passed to rb_proc_alloc. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
