Watson Zeng fa41ec052d tests: mem_alloc: workaround aggressive optimization As we don't use memory allocated in test_calloc, test_no_mem_malloc, and test_no_mem_realloc. malloc call can be optimized away (that really happens with ARC MWDT toolchain). That breaks the test. So disable optimization for these functions. Signed-off-by: Watson Zeng <zhiwei@synopsys.com>		2021-05-24 23:31:10 -04:00

Title: Kernel Access to Dynamic Memory Allocation functions provided by
Standard Libraries

Description:

This test verifies kernel access to the dynamic memory allocation functions
provided by standard C libraries supported in Zephyr:
NEWLIB and MINIMAL_LIB.
It is intended to catch issues in which a library is completely absent
or non-functional, and is NOT intended to be a comprehensive test suite
of all functionality provided by the libraries.

Building and Running Project:

This project outputs to the console.  It can be built and executed
on QEMU as follows:

    make run

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by outdated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info
