RISC-V: Implement the .SAT_TRUNC for scalar
This patch would like to implement the simple .SAT_TRUNC pattern
in the riscv backend. Aka:
Form 1:
#define DEF_SAT_U_TRUC_FMT_1(NT, WT) \
NT __attribute__((noinline)) \
sat_u_truc_##WT##_to_##NT##_fmt_1 (WT x) \
{ \
bool overflow = x > (WT)(NT)(-1); \
return ((NT)x) | (NT)-overflow; \
}
DEF_SAT_U_TRUC_FMT_1(uint32_t, uint64_t)
[ ... ]
But I haven't dug deeper than that.
