This changes GDB to use frame_info_ptr instead of frame_info * The substitution was done with multiple sequential `sed` commands: sed 's/^struct frame_info;/class frame_info_ptr;/' sed 's/struct frame_info \*/frame_info_ptr /g' - which left some issues in a few files, that were manually fixed. sed 's/\<frame_info \*/frame_info_ptr /g' sed 's/frame_info_ptr $/frame_info_ptr/g' - used to remove whitespace problems. The changed files were then manually checked and some 'sed' changes undone, some constructors and some gets were added, according to what made sense, and what Tromey originally did Co-Authored-By: Bruno Larsen <blarsen@redhat.com> Approved-by: Tom Tomey <tom@tromey.com>
