| Workaround: | use --opt_level=0 or 1 instead of 2

| Description |
|
With --opt_level=2, the optimizer generates "internal error" for arrays of pointers similar to below example: void foo(void) { char* argv[1]; parse_args(argv); }NOTE: earlier fix in CODEGEN-11223 missed a use case that this fix addresses. More details: static inline __erase_vector __parse_args(uint8_t* ptrInput, uint8_t* argv[])
{
/* code here */
}
Build it ... % cl2000 -@options.txt file.c "file.c", line 2639: warning #303-D: typedef name has already been declared (with same type) "file.c", line 2640: warning #303-D: typedef name has already been declared (with same type) "file.c", line 2679: warning #303-D: typedef name has already been declared (with same type) TP>> internal error: Bad kind: TYPE::type_pointed_to This is caused by a defect in the TI C/C++ Optimizer. TI Customer Support may be able to suggest a workaround to avoid this. Upgrading to the newest version of the compiler may fix this problem. Contact TI in the E2E support forums at http://e2e.ti.com under "Development Tools", "TI C/C++ Compiler". See the link titled "Submitting an issue". We need to see this ENTIRE error message and a complete, reproducible test case including ALL of the command-line options. Include the .pp file created by option --preproc_with_comment >> Compilation failure Replace that function with an extern declaration ... extern __erase_vector __parse_args(uint8_t* ptrInput, uint8_t* argv[]); ... and it builds clean. |
