 more undefined references to `GuestABI::Argument<X86PseudoInstABI, unsigned

I've implemented several customized pseudo-instructions on include/gem5/m5ops.h 
as follows:

bool PIMMultiplySize(sparse_mtx *A, sparse_mtx *B, sparse_mtx *C);
bool PIMAddSize(sparse_mtx *A, sparse_mtx *C);
bool PIMMergeSize(sparse_mtx *A, sparse_mtx *C, uint32_t num);
bool PIMMultiply(sparse_mtx *A, sparse_mtx *B, sparse_mtx *C);
bool PIMAdd(sparse_mtx *A, sparse_mtx *C);
bool PIMMerge(sparse_mtx *A, sparse_mtx *C, uint32_t num);
bool PIMGetSize(const char *file_path, uint32_t len, uint32_t *nrow,
    uint32_t *ncol);
bool PIMGetMatrix(uint32_t rpos, uint32_t cpos, void *mtx);
bool PIMGetMatrixSize(uint32_t rpos, uint32_t cpos, void *mtx);

And the simulator implementation is on arch/x86/pseudo_inst.hh as follows:

bool PIMMultiplySize(ThreadContext *tc, Addr A, Addr B, Addr C);
bool PIMAddSize(ThreadContext *tc, Addr A, Addr C);
bool PIMMergeSize(ThreadContext *tc, Addr Int, Addr C, uint32_t num);
bool PIMMultiply(ThreadContext *tc, Addr A, Addr B, Addr C);
bool PIMAdd(ThreadContext *tc, Addr A, Addr C);
bool PIMMerge(ThreadContext *tc, Addr Int, Addr C, uint32_t num);
bool PIMGetSize(ThreadContext *tc, Addr file_path, uint32_t len, Addr nrow,
    Addr ncol);
bool PIMGetMatrix(ThreadContext *tc, uint32_t rpos, uint32_t cpos, Addr mtx);
bool PIMGetMatrixSize(ThreadContext *tc, uint32_t rpos, uint32_t cpos,
    Addr mtx);

I'd like to know why this linking error happens. I didn't change anything on 
sim/guest_abi.hh, arch/x86/guest_abi.hh
