The Solaris Compact C Type Format, CTF, was introduced back in Solaris 9. It is the precursor to current GNU CTF, meant primarily for tools like the low-level debugger mdb or DTrace that would like to avoid the overhead of full DWARF-2 debugging information. However, for a long time creation required separate steps to convert DWARF information (version 2 only) to CTF in the input objects and later merge this into the final objects. The tools to do so were available, but they were barely documented and their use restricted to the core OS because of this difficulty. There's recently been a massive effort to simplify this and allow for wider adoption. The native linker has been extended to take GNU CTF info in the input objects and convert that to Solaris CTF itself. At the same time, the massively enhanced tools and the format itself are fully documented. To make this even simpler to use, this patch introduces a new -gsctf option to hide the details from users. At compile time, it just passes -gctf to the compiler, and at link time it invokes ld with -z ctf. Bootstrapped without regressions on i386-pc-solaris2.11 and sparc-sun-solaris2.11. 2025-11-23 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> gcc: * configure.ac (gcc_cv_ld_ctf): New check.
