I think essentially the code needs to know whenever frame pointers are used or not and then update (or not) rbp depending on that. Update compiler flags to explicitly set -f(no-)omit-frame-pointer, also add -D OMIT_FRAME_POINTER=1, the compile conditionally on OMIT_FRAME_POINTER? take care, Gerd -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
