Hi,
gcc trunk has failed to build PowerPC64 kernels for a month or so. The issue
is in oprofile, which is common code but ends up being sucked into
arch/powerpc and therefore subject to the -Werror applied to arch/powerpc:
linux/arch/powerpc/oprofile/../../../drivers/oprofile/oprofile_stats.c: In
function ‘oprofile_create_stats_files’:
linux/arch/powerpc/oprofile/../../../drivers/oprofile/oprofile_stats.c:55:25:
error: ‘%d’ directive output may be truncated writing between 1 and 11 bytes
into a region of size 7 [-Werror=format-truncation=]
snprintf(buf, 10, "cpu%d", i);
^~
linux/arch/powerpc/oprofile/../../../drivers/oprofile/oprofile_stats.c:55:21:
note: using the range [1, -2147483648] for directive argument
snprintf(buf, 10, "cpu%d", i);
^~~~~~~
linux/arch/powerpc/oprofile/../../../drivers/oprofile/oprofile_stats.c:55:3:
note: format output between 5 and 15 bytes into a destination of size 10
snprintf(buf, 10, "cpu%d", i);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
