* test: Pass commandline arguments to run_testTom Hughes2020-05-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | run_test is called by the "runtest" console command. Console commands can take arguments, so pass along the arguments to run_test to allow parameters to be passed to run_test. The following command was used for automatic replacement: git grep --name-only 'void run_test(void)' |\ xargs sed -i 's#void run_test(void)#void run_test(int argc, char **argv)##' BRANCH=none BUG=b:155897971 TEST=make buildall -j TEST=Build and flash flash_write_protect test > runtest 1 Signed-off-by: Tom Hughes <tomhughes@chromium.org> Change-Id: Ib20b955d5ec6b98f525c94c24aadefd7a6a320a5 Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/ec/+/2209418 Reviewed-by: Yicheng Li <yichengli@chromium.org> Commit-Queue: Yicheng Li <yichengli@chromium.org> Tested-by: Yicheng Li <yichengli@chromium.org>
* builtin: Introduce and use inttypes.hEvan Green2019-10-051-1/+1
| | | | | | | | | | | | | | | | | | | | | In order to pass the right printf format specifiers for certain types that are compiled both in 32-bit EC and 64-bit host environments, standard macros PRIx64 and PRId64 must be introduced. These specify the correct printf format specifier in the given compilation environment for printing a 64-bit value. On the host, inttypes.h already exists. Add an inttypes.h for the EC codebase so that these macros can be used where they're needed.
