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/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 a02cbc7ffe529ed58b6bbe54652104fc2c88bd77 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_storcenter_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- storcenter_defconfig WARNING: unmet direct dependencies detected for PPC_INDIRECT_PCI Depends on [n]: PCI [=n] Selected by [y]: - MPC10X_BRIDGE [=y] WARNING: unmet direct dependencies detected for PPC_INDIRECT_PCI Depends on [n]: PCI [=n] Selected by [y]: - MPC10X_BRIDGE [=y] # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next_storcenter_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x4fe7b4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-5.4.0-rc2-ga02cbc7ffe52 Created: Wed Oct 30 01:54:00 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2608287 Bytes = 2547.16 KiB = 2.49 MiB Load Address: 00500000 Entry Point: 00500894 Completed OK # rm -rf /kisskb/build/powerpc-next_storcenter_defconfig_powerpc-gcc5 # Build took: 0:00:23.892680
