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/ia64-linux/bin/ia64-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/ia64-linux/bin/ia64-linux-ld --version # < git log --format=%s --max-count=1 a02cbc7ffe529ed58b6bbe54652104fc2c88bd77 # < make -s -j 120 ARCH=ia64 O=/kisskb/build/powerpc-next_ia64-defconfig_ia64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/ia64-linux/bin/ia64-linux- defconfig # make -s -j 120 ARCH=ia64 O=/kisskb/build/powerpc-next_ia64-defconfig_ia64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/ia64-linux/bin/ia64-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] /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] /kisskb/src/mm/vmstat.c: In function 'sysctl_vm_numa_stat_handler': /kisskb/src/mm/vmstat.c:90:5: warning: 'oldval' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:338:21: note: 'pdeo' was declared here /kisskb/src/fs/udf/unicode.c: In function 'udf_name_conv_char': /kisskb/src/fs/udf/unicode.c:132:8: warning: 'c' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/nfs/read.c: In function 'nfs_read_completion': /kisskb/src/fs/nfs/read.c:196:5: warning: value computed is not used [-Wunused-value] /kisskb/src/fs/nfs/read.c: In function 'nfs_readpage': /kisskb/src/fs/nfs/read.c:352:2: warning: value computed is not used [-Wunused-value] /kisskb/src/mm/hugetlb.c: In function 'alloc_pool_huge_page': /kisskb/src/mm/hugetlb.c:1497:5: warning: 'page' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/nfsd/nfs4xdr.c: In function 'nfsd4_encode_components_esc': /kisskb/src/fs/nfsd/nfs4xdr.c:2076:9: warning: 'str' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/usb/core/devio.c: In function 'async_completed': /kisskb/src/drivers/usb/core/devio.c:625:23: warning: 'errno' may be used uninitialized in this function [-Wuninitialized] No errors detected in 21694 functions.
