Using the C7x compiler that comes with the J721E RTOS SDK, I got the following output compiling some of our code:
>>>> Optimizer terminated abnormally >>>> in function complexDivideRealConst() >>>> in file "benchmark_float.c" 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
This compiler version included with the SDK is "ti-cgt-c7000_3.0.0.STS".
I have managed to get a minimal reproduction case, as follows:
#include <c7x.h>
#include <stdint.h>
#define NUM_BATCHES 512
#define NUM_POINTS 512
static __SE_TEMPLATE_v1 divideSE;
static __SA_TEMPLATE_v1 divideSA;
// Ok for out to equal either dividend (destructive)
void complexDivideRealConst(float *dividend, uint32_t divisor, float *out)
{
__SE0_OPEN((void *)dividend, divideSE);
__SA0_OPEN(divideSA);
for(int i = 0; i < NUM_BATCHES * NUM_POINTS * 2 / 16; i++)
*__SA0ADV(float16, out) = __SE0ADV(float16) / divisor;
__SE0_CLOSE();
__SA0_CLOSE();
}
Which shows the problem when the following compilation command line:
/opt/ti-cgt-c7000_3.0.0.STS/bin/cl7x -c --c99 -O3 --issue_remarks --emit_warnings_as_errors -pden --abi=eabi --silicon_version=7100 --silicon_errata_i2117 -I/opt/ti-cgt-c7000_3.0.0.STS/include -D=C71="C71" -D=C7100 -D=__C7X_UNSTABLE_API -ppc --preproc_with_compile benchmark_float.c -fe benchmark_float.o
I'll attempt to attach the pre-processed output as requested (can't seem to do so here on initial post).
