Subject: [PATCH v2] RISC-V: Bugfix for resolve_overloaded_builtin[PR113420]
From: xuli
v2:
Avoid internal ICE for the case below.
vint8mf8_t test_vle8_v_i8mf8_m(vbool64_t vm, const int32_t *rs1, size_t vl) {
return __riscv_vle8(vm, rs1, vl);
}
v1:
Change the hash value of overloaded intrinsic from considering
all parameter types to:
1. Encoding vector data type
2. In order to distinguish vle8_v_i8mf8_m(vbool64_t vm, const int8_t *rs1,
size_t vl)
and vle8_v_u8mf8_m(vbool64_t vm, const uint8_t *rs1, size_t vl), encode the
pointer type
3. In order to distinguish vfadd_vv_f32mf2_rm(vfloat32mf2_t vs2, vfloat32mf2_t
vs1, size_t vl)
and vfadd_vv_f32mf2(vfloat32mf2_t vs2, vfloat32mf2_t vs1, size_t vl), encode
the number of
parameters. The same goes for the vxrm intrinsics.
