/* { dg-do run { target arm*-*-symbianelf* arm*-*-eabi* } } */ /* { dg-options "" } */ /* This file tests most of the non-C++ run-time helper functions described in Section 4 of the "Run-Time ABI for the ARM Architecture". These are basic tests; they do not try to validate all of the corner cases in these routines. The functions not tested here are: __aeabi_cdcmpeq __aeabi_cdcmple __aeabi_cdrcmple __aeabi_cfcmpeq __aeabi_cfcmple __aeabi_cfrcmple __aeabi_ldivmod __aeabi_uldivmod __aeabi_idivmod __aeabi_uidivmod These functions have non-standard calling conventions that would require the use of inline assembly to test. It would be good to add such tests, but they have not yet been implemented. There are also no tests for the "division by zero", "memory copying, clearing, and setting" functions. */ #include <stdio.h> #include <stdlib.h> #include <math.h> #define decl_float(code, type) \ extern type __aeabi_ ## code ## add (type, type); \ extern type __aeabi_ ## code ## div (type, type); \ extern type __aeabi_ ## code ## mul (type, type); \ extern type __aeabi_ ## code ## neg (type); \ extern type __aeabi_ ## code ## rsub (type, type); \ extern type __aeabi_ ## code ## sub (type, type); \ extern int __aeabi_ ## code ## cmpeq (type, type); \ extern int __aeabi_ ## code ## cmplt (type, type); \ extern int __aeabi_ ## code ## cmple (type, type); \ extern int __aeabi_ ## code ## cmpge (type, type); \ extern int __aeabi_ ## code ## cmpgt (type, type); \ extern int __aeabi_ ## code ## cmpun (type, type); \ extern int __aeabi_ ## code ## 2iz (type); \ extern unsigned int __aeabi_ ## code ## 2uiz (type); \ extern long long __aeabi_ ## code ## 2lz (type); \ extern unsigned long long __aeabi_ ## code ## 2ulz (type); \ extern type __aeabi_i2 ## code (int); \ extern type __aeabi_ui2 ## code (int); \ extern type __aeabi_l2 ## code (long long); \ extern type __aeabi_ul2 ## code (unsigned long long); \ \ type code ## zero = 0.0; \ type code ## one = 1.0; \ type code ## two = 2.0; \ type code ## four = 4.0; \ type code ## minus_one = -1.0; \ type code ## minus_two = -2.0; \ type code ## minus_four = -4.0; \ type code ## epsilon = 1E-32; \ type code ## NaN = 0.0 / 0.0; decl_float (d, double) decl_float (f, float) extern float __aeabi_d2f (double); extern double __aeabi_f2d (float); extern long long __aeabi_lmul (long long, long long); extern long long __aeabi_llsl (long long, int); extern long long __aeabi_llsr (long long, int); extern long long __aeabi_lasr (long long, int); extern int __aeabi_lcmp (long long, long long); extern int __aeabi_ulcmp (unsigned long long, unsigned long long); extern int __aeabi_idiv (int, int); extern unsigned int __aeabi_uidiv (unsigned int, unsigned int); extern int __eabi_uread4 (void *); extern int __eabi_uwrite4 (int, void *); extern long long __eabi_uread8 (void *); extern long long __eabi_uwrite8 (long long, void *); #define eq(a, b, type, abs, epsilon, format) \ { \ type a1; \ type b1; \ \ fprintf (stderr, "%d: Test %s == %s\n", __LINE__, #a, #b); \ a1 = a; \ b1 = b; \ if (abs (a1 - b1) > epsilon) \ { \ fprintf (stderr, "%d: " format " != " format "\n", \ __LINE__, a1, b1); \ abort (); \ } \ } #define ieq(a, b) eq (a, b, int, abs, 0, "%d") #define ueq(a, b) eq (a, b, unsigned int, abs, 0, "%u") #define leq(a, b) eq (a, b, long long, abs, 0, "%lld") #define uleq(a, b) eq (a, b, unsigned long long, abs, 0, "%llu") #define feq(a, b) eq (a, b, float, fabs, fepsilon, "%f") #define deq(a, b) eq (a, b, double, fabs, depsilon, "%g") int main () { unsigned char bytes[256]; int i; /* Table 2.
