I advise reviewing this whole comment, and the Linux port in general, for
whether it is still current.
I don't see the kernel port as of Linux 3.10, and Linux kernel policy as I
understand it is that new architectures are expected to use the generic
syscall interface, which only has rt_sigreturn. So, references to the old
non-realtime sigreturn are suspect for new architectures. Similarly,
references to glibc 2.1.2 are suspect for an architecture with no glibc
port as of 2.18. (If the Linux ABI isn't fully confirmed with the
upstream Linux kernel community, you might want to submit the non-Linux
parts of the GDB port and come back to the Linux parts later.)
Hi Joseph,
This part is based on our outdated glibc 2.5 porting,
and we are still working on glibc 2.18,
so I agree we withdraw this part in revised patch,
and come back when our glibc 2.18 porting is ready.
Thanks for pointing out this and the suggestions.
I will review the patch thoroughly again.
