Tool/software:
Hi TI,
I have a compiler failure building my C7X app, made of C++ code.
I was able to shrink the code to the following :
#include <c7x_scalable.h>
void test_func (const cfloat * RESTRICT X,cfloat * RESTRICT Y){for(uint32_t vt = 0u; vt < 10; vt++) Y[vt] = X[vt];}
void caller (const cfloat * RESTRICT const zi, cfloat * RESTRICT zo){test_func(zi, zo);}_
I compiled this with CGT 4.1.0 for C7X (DSP of J784S4).
With -DRESTRICT="", I have a compiler warning "advice #35000-D: (Performance) Consider adding the
restrict qualifier to the declaration of "Y" to improve loop performance."
With -DRESTRICT=restrict the compiler crashes if opt_level is 2 or 3 (OK with 0 or 1).
