5 gcc/
6 * config/arm/arm.c (arm_init_libfuncs): Change __gnu_f2h_ieee to
7 __aeabi_f2h, __gnu_f2h_alternative to __aeabi_f2h_alt, __gnu_h2f_ieee
8 to __aeabi_h2f, and __gnu_h2f_alternative to __aeabi_h2f_alt.
9 * config/arm/fp16.c (__gnu_f2h_internal): Change return type to
10 unsigned int. Change 'sign' variable likewise.
11 (__gnu_h2f_internal): Set to static inline.
12 Change return type to unsigned int. Change 'sign' variable likewise.
13 (ALIAS): New define.
14 (__gnu_f2h_ieee): Change unsigned short to unsigned int.
15 (__gnu_h2f_ieee): Likewise.
16 (__gnu_f2h_alternative): Likewise.
17 (__gnu_h2f_alternative): Likewise.
18 (__aeabi_f2h, __aeabi_h2f): New aliases.
19 (__aeabi_f2h_alt, __aeabi_h2f_alt): Likewise.
20 * config/arm/sfp-machine.h (__extendhfsf2): Set to __aeabi_h2f.
21 (__truncsfhf2): Set to __aeabi_f2h.

24 * g++.dg/ext/arm-fp16/arm-fp16-ops-5.C: Check for __aeabi_h2f
25 and __aeabi_f2h.
26 * g++.dg/ext/arm-fp16/arm-fp16-ops-6.C: Likewise.
27 * gcc.dg/torture/arm-fp16-ops-5.c: Likewise.
