Vineet Gupta 67a9a71183 [ARC]PR 88409: miscompilation due to missing cc clobber in longlong.h macros ... simple test such as below was failing. | void main(int argc, char *argv[]) | { | size_t total_time = 115424; // expected 115.424 | double secs = (double)total_time/(double)1000; | printf("%s %d %lf\n", "secs", total_time, secs); // prints 113.504 | printf("%d\n", (size_t)secs); | } The printf eventually called into glibc stdlib/divrem.c:__mpn_divrem() which uses the __arc__ specific inline asm macros from longlong.h which were causing miscompilation. include/ 2019-03-28 Vineet Gupta <vgupta@synopsys.com> PR 89877 * longlong.h [__arc__] (add_ssaaaa): Add cc clobber (sub_ddmmss): Likewise.
