Hi,
On -CURRENT buildkernel fails when WITH_CLANG_IS_CC declared with:
/usr/src/sys/modules/ath/../../dev/ath/if_ath_debug.c:184:24: error:
array index 21 is past the end of the array (which contains
21 elements) [-Werror,-Warray-bounds]
eds->ds_hw[20], eds->ds_hw[21]);
^ ~~
@/dev/ath/ath_hal/ah_desc.h:229:2: note: array 'ds_hw' declared here
uint32_t ds_hw[21]; /* includes buf/len */
^
1 error generated.
*** [if_ath_debug.o] Error code 1
Attached patch bumps array size to 22 in decleration which stops the error.
Sevan
