* configure.tgt: Fix i?86-*-linux* entry. * rt/sat_arithmetic.c (__hsail_sat_add_u32, __hsail_sat_add_u64, __hsail_sat_add_s32, __hsail_sat_add_s64): Use __builtin_add_overflow. (__hsail_sat_sub_u8, __hsail_sat_sub_u16): Remove pointless for overflow over maximum. (__hsail_sat_sub_u32, __hsail_sat_sub_u64, __hsail_sat_sub_s32, __hsail_sat_sub_s64): Use __builtin_sub_overflow. (__hsail_sat_mul_u32, __hsail_sat_mul_u64, __hsail_sat_mul_s32, __hsail_sat_mul_s64): Use __builtin_mul_overflow. * rt/arithmetic.c (__hsail_borrow_u32, __hsail_borrow_u64): Use __builtin_sub_overflow_p. (__hsail_carry_u32, __hsail_carry_u64): Use __builtin_add_overflow_p. * rt/misc.c (__hsail_groupbaseptr, __hsail_kernargbaseptr_u64): Cast pointers to uintptr_t first before casting to some other integral type. * rt/segment.c (__hsail_segmentp_private, __hsail_segmentp_group): Likewise. * rt/queue.c (__hsail_ldqueuereadindex, __hsail_ldqueuewriteindex, __hsail_addqueuewriteindex, __hsail_casqueuewriteindex, __hsail_stqueuereadindex, __hsail_stqueuewriteindex): Cast integral value to uintptr_t first before casting to pointer. * rt/workitems.c (__hsail_alloca_pop_frame): Cast memcpy first argument to void * to avoid warning.
