When using -linkshared, the external linker on ppc64x cannot always handle the direct branch to syscall.Syscall and similar similar functions when the offset is too far. Instead it should be done as a BL which can then be called through a procedure linkage table entry. This change removes functions Syscall, Syscall6, RawSyscall, RawSyscall6 from asm_linux_ppc64x.s and instead creates Go functions which call their corresponding functions in the syscall package. As Go functions, they can be inlined with the help of CL 147361. Fixes golang/go#16662 Change-Id: Ibd2b6ec15b0781c3d7db25e249a3ffc9e1c2884b Reviewed-on: https://go-review.googlesource.com/c/146518 Run-TryBot: Lynn Boger <laboger@linux.vnet.ibm.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Ian Lance Taylor <iant@golang.org> Reviewed-by: Tobias Klauser <tobias.klauser@gmail.com>
