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-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 a02cbc7ffe529ed58b6bbe54652104fc2c88bd77 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc40x_defconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc40x_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_ppc40x_defconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/kernel/head_40x.S: Assembler messages: /kisskb/src/arch/powerpc/kernel/head_40x.S:802: Warning: invalid register expression INFO: Uncompressed kernel (size 0x5c799c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5c799c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5c799c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5b72bc) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5c799c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.4.0-rc2-ga02cbc7ffe52 Created: Wed Oct 30 02:41:51 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2871166 Bytes = 2803.87 KiB = 2.74 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.4.0-rc2-ga02cbc7ffe52 Created: Wed Oct 30 02:41:51 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2909551 Bytes = 2841.36 KiB = 2.77 MiB Load Address: 00600000 Entry Point: 00601860 Image Name: Linux-5.4.0-rc2-ga02cbc7ffe52 Created: Wed Oct 30 02:41:52 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2909852 Bytes = 2841.65 KiB = 2.78 MiB Load Address: 00600000 Entry Point: 00601ad4 Completed OK # rm -rf /kisskb/build/powerpc-next_ppc40x_defconfig_powerpc-gcc8 # Build took: 0:01:00.543646
