ARMCC: VARIABLES GET LOCATED TO RW RATHER THAN ZIInformation in this article applies to:
QUESTIONFor the following example code: char test_array[8]; The linker reports these memory sizes RW data = 8 and ZI data = 0 While for: char test_array[9]; The linker reports these memory sizes RW data = 0 and ZI data = 9. Why is the latter in the ZI section but the former isn't? Is there a way to change the linker behaviour? ANSWERData objects smaller than 9 bytes get moved to the RW region for optimization reasons. This threshold can be controlled by the bss_threshold compiler switch. To enable this option in µVision please add the compiler switch in Options for Target — C/C++ — Misc Controls field. Example: --bss_threshold=0 Note:
