#     selftests/powerpc: Fix build failures with GCC 9
#     
#     GCC 9 fails to build some of the ptrace TM tests, with errors such as:
#     
#       ptrace-tm-spd-vsx.c: In function 'tm_spd_vsx':
#       ptrace-tm-spd-vsx.c:51:2: error: listing the stack pointer register 'r1' in a clobber list is deprecated [-Werror=deprecated]
#          51 |  asm __volatile__(
#             |  ^~~
#       ptrace-tm-spd-vsx.c:51:2: note: the value of the stack pointer after an 'asm' statement must be the same as it was before the statement
#     
#     Which is probably fair enough.
#     
#     Some of these inline asm blocks are doing quite a lot and are probably
#     pushing the boundaries of what's sane to do with inline asm, but they
#     shouldn't actually be returning with r1 modified.
#     
#     So drop r1 from the clobbers for now, we should probably rewrite them
#     to be real asm functions at some point.
