| Affected Platform/Device: | default |
| Workaround: | This issue should not arise when using the 2.1.0.LTS (or later) version of the TI Arm Clang Compiler Tools since a fix to a related issue https://sir.ext.ti.com/jira/browse/EXT_EP-10829 will prevent the linker from failing due to this issue. |
| Description |
|
An externally defined symbol that is referenced from a static function or variable whose section is included in the reference graph should be included in the intermediate representation's symbol table that is presented to the link-time optimizer for recompilation. For example, if t1.c contains a static function definition that references RTS functions expf and logf and the address of the static function is made available in a data object that is externally accessible, then the expf and logf symbols should be recognized and included in t1.o's intermediate representation module as legitimate unresolved symbol references. |
