However they should all return # to C with the value in r1 restored, so I think it's legitimate to say # r1 is not clobbered. # # As Segher points out, the r1 clobbers may have been added because of # the use of `or 1,1,1`, however that doesn't actually clobber r1. # # Segher also points out that some of these tests do clobber LR, because # they call functions, and that is not listed in the clobbers, so add # that where appropriate. # # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20191029095324.14669-1-mpe@ellerman.id.au # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 a02cbc7ffe529ed58b6bbe54652104fc2c88bd77 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_powerpc-allnoconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- allnoconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_powerpc-allnoconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:204:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] Completed OK # rm -rf /kisskb/build/powerpc-next_powerpc-allnoconfig_powerpc-gcc4.6 # Build took: 0:00:16.394953
