Other mature backends (i386, x86_64, arm64) all define PROMOTE_RET, which forces explicit sign/zero extension of narrow return types at the caller side. Without it, riscv64 relied on the assumption that RV64 registers are always sign-extended, which may not hold when interfacing with non-TCC compilers. Verified on Spacemit X100 (riscv64): self-compilation is self-consistent across 3 layers. test3 reference mismatch is expected — the test intentionally invokes UB via type-punned function pointers (csf macro). |
