H.J. Lu <hjl.tools at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC|hjl at gcc dot gnu.org |hjl.tools at gmail dot com --- Comment #1 from H.J. Lu <hjl.tools at gmail dot com> --- Since /* Clear all scratch integer registers. */ #define clear_int_hardware_registers \ asm __volatile__ ("xor %%eax, %%eax\n\t" \ "xor %%edx, %%edx\n\t" \ "xor %%ecx, %%ecx\n\t" \ ::: "eax", "edx", "ecx"); /* Clear both hardware and register structs for integers, excluding the one used to return aggregate. */ #define clear_non_sret_int_registers \ clear_struct_registers \ clear_non_sret_int_hardware_registers #undef D #define D(I) { static struct S_ ## I s; current_test = I; struct_addr = (void*)&s; \ clear_non_sret_int_registers; \ s = WRAP_RET(f_ ## I) (); \ check_all(class_ ## I, sizeof(s)); \ } trash PIC register, iamcu tests should add -fno-PIC -no-pie.
