+ * amd64-linux-nat.c (amd64_linux_fetch_inferior_registers):
+ Check whether have_ptrace_getregset is TRIBOOL_TRUE explicitly.
+ (amd64_linux_store_inferior_registers): Likewise.
+ * arm-linux-nat.c (fetch_fpregister): Likewise.
+ (fetch_fpregs, store_fpregister): Likewise.
+ (store_fpregister, store_fpregs): Likewise.
+ (fetch_register, fetch_regs): Likewise.
+ (store_register, store_regs): Likewise.
+ (fetch_vfp_regs, store_vfp_regs): Likewise.
+ (arm_linux_read_description): Check have_ptrace_getregset is
+ TRIBOOL_UNKNOWN. Set have_ptrace_getregset to TRIBOOL_TRUE
+ or TRIBOOL_FALSE.
+ * i386-linux-nat.c (fetch_xstateregs): Check
+ have_ptrace_getregset is not TRIBOOL_TRUE.
+ (store_xstateregs): Likewise.
+ * linux-nat.c (have_ptrace_getregset): Change its type to
+ enum tribool.
+ * linux-nat.h (tribool): New enum.
+ * x86-linux-nat.c (x86_linux_read_description): Use enum tribool.
+ Check whether have_ptrace_getregset is TRIBOOL_TRUE.

* NEWS: Mention Sun's version of stabs is no longer supported.
