Hello, here's some more work on the x86_64-gnu glibc port. Large parts of glibc (almost all of it?) builds, in particular mach/subdir_lib builds cleanly.
Patch 6 is really unrelated to the rest of the changes, it's just a small thing that I've noticed while single-stepping through glibc startup, trying to understand which order things are getting called in, and from where. Patch 8/9 adds i386_fsgs_base_state to Mach headers. Does this look reasonable? I have not written an implementation. Any volunteers? :) Then patch 9/9 adds a fairly complete implementation of tls.h based on that API. It turned out that thread_state.h did not need large changes compared to the i386 version after all, so consider applying Flavio's patch ("Define PC, SP and SYSRETURN for hurd x86_64") instead of the version my patch adds (but keep the rest of my patch). I'm not super sure that the thing I've done with __libc_tls_initialized is correct / makes sense; please do take a look! Large parts remaining: * ucontext / sigcontext * intr_msg / signal trampoline Sergey
