Subject: Define PC, SP and SYSRETURN for hurd x86_64
X-Git-Tag: glibc-2.38~555
X-Git-Url: https://sourceware.org/git/?a=commitdiff_plain;h=b5b27ff1519d6ca20efcec46bc26964e1c7da68a;p=glibc.git

Define PC, SP and SYSRETURN for hurd x86_64

Moved thread_state.h to x86 directory since we only need to customize
those 3 definitions.
