-Subject: [PATCH] regression 41xx: prevent unsafe-loop-optimizations build
- error
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Add -Wno-unsafe-loop-optimizations directive since regression_4100.c
-fails to build on some recent toolchains as GCC 7.3.0 and 7.4.0 with
-an error trace like below. Note building with GCC 8.2.1 does not
-reproduce the build issue.
-
-/path/to/optee_test/host/xtest/regression_4100.c: In function ‘convert_from_string’:
-/path/to/optee_test/host/xtest/regression_4100.c:448:8: error: missed loop optimization, the loop counter may overflow [-Werror=unsafe-loop-optimizations]
- while (spos) {
- ^
-/path/to/optee_test/host/xtest/regression_4100.c:455:6: error: missed loop optimization, the loop counter may overflow [-Werror=unsafe-loop-optimizations]
- if (!spos)
- ^
-
-The GNU Makefile build sequence defines -Wno-unsafe-loop-optimizations
-for the whole xtest sources while CMake build sequence defines it
-specifically for regression_4100.c among xtest source files.
