This is an ABI breaking change, but
typedef int greg_t;
is not a useful definition on aarch64.
greg_t is usually used for defining gregset_t which is used
in mcontext_t. The general registers in mcontext_t can only
be accessed by target specific code and on aarch64 greg_t
is not needed for that so this change is not supposed to break
existing code, just fix the definition.
[BZ #18648]
* sysdeps/unix/sysv/linux/aarch64/sys/ucontext.h (greg_t): Change the
definition to elf_greg_t.
(Added another BZ entry that was missed in the previous commit).
This patch moves the AArch64 port to the main sysdeps hierarchy. The
move is essentially:
git mv ports/sysdeps/aarch64 sysdeps/aarch64
git mv ports/sysdeps/unix/sysv/linux/aarch64 sysdeps/unix/sysv/linux/aarch64
The README is updated and I've updated ChangeLog.aarch64 along the
lines of the ARM move. The AArch64 build has been tested to confirm
that there were no changes in objdump -dr output or the shared
objects.
