+Estimating stack usage +----------------------
isn't this usable for any target and not just omap3 ?
+With gcc 4.6 (and later) and the use of GNU cflow it is possible to estimate stack usage at various points in run sequence of SPL. The -fstack-usage option to gcc will produce '.su' files (such as arch/arm/cpu/armv7/syslib.su) that will give stack usage information and cflow can construct program flow. + +Must have gcc 4.6 or later, which supports -fstack-usage
tools/checkpatch.pl is also pretty useful and doesn't require any compile version
+$ for F in `cd spl; find -name *.su`; do \
- echo $F | sed -e 's/.su$/.c/'; done > used-spl.list
find spl -name '*.su' | sed -e 's:^spl/::' -e 's:[.]su$:.c:' > used-spl.list -mike
