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. # # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # <
