With tilepro support removal we can now simplify internal tile support by moving the directory structure to avoid the unnecessary directory levels in tile/tilegx both on generic and linux folders. Checked with a build for tilegx-linux-gnu and tilegx-linux-gnu-32 with and without the patch, there is no difference in generated binary with a dissassemble. * stdlib/bug-getcontext.c (do_test): Remove tilepro mention in comment. * sysdeps/tile/preconfigure: Remove tilegx folder. * sysdeps/tile/tilegx/Implies: Move definitions to ... * sysdeps/tile/Implies: ... here. * sysdeps/tile/tilegx/Makefile: Move rules to ... * sysdeps/tile/Makefile: ... here. * sysdeps/tile/tilegx/atomic-machine.h: Move definitions to ... * sysdeps/tile/atomic-machine.h: ... here. Add include guards. * sysdeps/tile/tilegx/bits/wordsize.h: Move to ... * sysdeps/tile/bits/wordsize.h: ... here. * sysdeps/tile/tilegx/*: Move to ... * sysdeps/tile/*: ... here. * sysdeps/tile/tilegx/tilegx32/Implies: Move to ... * sysdeps/tile/tilegx32/Implies: ... here. * sysdeps/tile/tilegx/tilegx64/Implies: Move to ... * sysdeps/tile/tilegx64/Implies: ... here. * sysdeps/unix/sysv/linux/tile/tilegx/Makefile: Move definitions to ... * sysdeps/unix/sysv/linux/tile/Makefile: ... here. * sysdeps/unix/sysv/linux/tile/tilegx/*: Move to ... * sysdeps/unix/sysv/linux/tile/*: ... here. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx32/*: Move to ... * sysdeps/unix/sysv/linux/tile/tilegx32/*: ... here. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/*: Move to ... * sysdeps/unix/sysv/linux/tile/tilegx64/*: ... here.
