Mostly 20 years ago, if I remember correctly, it was me who implemented the ptrace syscall in SuperH kernel, and put something to GDB for native debugging. It was under the GNU/Linux for SuperH Project. Me, Kaz Kojima, Toshinobu Sugioka, and Takashi Yoshii were all working together at that time. Before the ptrace system call, or any part of the kernel, as a start, I wrote my own initial program loader for SuperH which has GDB serial debug support. Then, I ported the kernel to SH-3. After my first submission of the patch to lkml, I realized that Kaz, Toshinobu, and Stuart Menefy were also having their own ports of SuperH. I managed to merge all efforts. I and Kaz designed the shared object ABI for SuperH, and implemented in glibc, gcc, binutils, and GDB. For all of GNU toolchain changes and glibc, I assigned my copyright to FSF. So did Kaz Kojima. After that, it was Toshinobu Sugioka who kept working the GDB patchset, as well as other patches to distribute his own RPM based distribution. Last year, I determined that the GDB patchset (of Adrian) was originally came from Toshinobu Sugioka, via Takashi Yoshii. So, I asked his copyright assignment to FSF. He did. It was handled with the ticket of [gnu.org #1227959]. I received the confrmation from FSF, in the message of: Date: Wed, 26 Jul 2017 10:06:13 -0400 Message-ID: ... which was also sent to GDB maintainers. --
