you are right. vint8mf8_t test_vle8_v_i8mf8_m(vbool64_t vm, const int32_t *rs1, size_t vl) { return __riscv_vle8(vm, rs1, vl); } This will cause ICE. I tried clang and it will also cause ICE. xuli1@eswincomputing.com From: juzhe.zhong@rivai.ai Date: 2024-01-19 15:53 To: Li Xu; gcc-patches CC: kito.cheng; palmer; zhengyu; pan2.li; Li Xu Subject: Re: [PATCH] RISC-V: Bugfix for resolve_overloaded_builtin[PR113420] Could you add a test for vle with mask? For example: __riscv_vle8 which overload __riscv_vle8_v_i8mf8_m and __riscv_vle8_v_u8mf8_m You are using pointer type and mask type to resolve it. So this pointer type is expecting const int8_t or const uint8_t. Could you add test: 1.__riscv_vle8 (const int8_t *...) 2. __riscv_vle8 (const uint8_t *...) 3. __riscv_vle8 (const int32_t *...) ---> I worry this will cause ICE since pointer type doesn't match the expecting type, I wonder whether it will cause ICE while resolving API.

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.
