| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of manual copy loop to shift list elements. Decreases time spent in Tcl_ListObjReplace() from 5.2% to 1.7% of overall runtime of tclbench on a ppc 7455 (i.e. 200% speed increase). [Patch 1064243] * generic/tclHash.c: hoisted some constant pointer dereferences out of loops to eliminate redundant loads that the gcc optimizer didn't deal with. Decreases time spend in Tcl_FindHashEntry() by 10% over a full run of the tcl testuite on a ppc 7455. [Patch 1064243]

| | | | | | | | | | | | | | | | | | They still cannot be called (no change in functionality), but at least they now do exactly the same as the Tcl_(Find|Create)HashEntry macro's, so the confusion addressed in this Bug report is gone. (Backported from Tcl 8.6)

| | | | | | | | | | | | | | | | * generic/tclHash.c: Tcl_FindHashEntry() now calls Tcl_CreateHashEntry() with a newPtr set to NULL: this would have caused a segfault previously and eliminates duplicated code.
