/* Target-dependent structure in gdbarch. */
gdb: rename gdbarch_tdep struct to fix g++ 4.8 build After the commit: commit 08106042d9f5fdff60c129bf33190639f1a98b2a Date: Thu May 19 13:20:17 2022 +0100 gdb: move the type cast into gdbarch_tdep GDB would no longer build using g++ 4.8. The issue appears to be some confusion caused by GDB having 'struct gdbarch_tdep', but also a templated function called 'gdbarch_tdep'. Prior to the above commit the gdbarch_tdep function was not templated, and this compiled just fine. Note that the above commit compiles just fine with later versions of g++, so this issue was clearly fixed at some point, though I've not tried to track down exactly when. In this commit I propose to fix the g++ 4.8 build problem by renaming 'struct gdbarch_tdep' to 'struct gdbarch_tdep_base'. This rename better represents that the struct is only ever used as a base class, and removes the overloading of the name, which allows GDB to build with g++ 4.8. I've also updated the comment on 'struct gdbarch_tdep_base' to fix a typo, and the comment on the 'gdbarch_tdep' function, to mention that in maintainer mode a run-time type check is performed.

Change GDB to use frame_info_ptr 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>
