New Revision: 228781
URL: http://svn.freebsd.org/changeset/base/228781
Log:
When building with clang, disable -Warray-bounds for sys/dev/asr/asr.c,
as it gets the following warning:
sys/dev/asr/asr.c:1836:29: warning: array index of '58' indexes past the end
of an array (that contains 1 element) [-Warray-bounds]
while ((len > 0) && (sg < &((PPRIVATE_SCSI_SCB_EXECUTE_MESSAGE)
^
sys/dev/asr/i2omsg.h:934:8: note: array 'Simple' declared here
I2O_SGE_SIMPLE_ELEMENT Simple[1];
^
This is a false positive, since I2O_SG_ELEMENT::Simple is not declared
as a C99 flexible array member, but in the old (but more portable) way.
At run-time, the proper number of array elements will hopefully have
been allocated.
