block_end_with_jump to a block question

Hi,

I created a a few blocks using gcc_jit_function_new_block.
While I have a jit function param coming in as “index”.
But the “index” has a type as gcc_jit_lvalue, which cannot be consider as an integer, thus, I cannot do gcc_jit_block_end_with_jump( block, NULL, elem_block[index].
Is there a trick to do this?
Here’s the code.



gcc_jit_lvalue *dst_input = gcc_jit_function_new_local( func, NULL, char_ptr_ptr_type, "dst_input" ),

                   *src_val = gcc_jit_function_new_local( func, NULL, char_ptr_type, "src_val" ),

                   *src_loop = gcc_jit_function_new_local( func, NULL, char_ptr_type, "src_loop" ),

                   *index_val = gcc_jit_function_new_local( func, NULL, int_ptr_type, "index_val" ),

                   *disp_val = gcc_jit_function_new_local( func, NULL, sizet_ptr_type, "disp_val" ),

                   *maxdata_val = gcc_jit_function_new_local( func, NULL, sizet_ptr_type, "maxdata_val" );


    gcc_jit_block_add_assignment( block, NULL, dst_input, gcc_jit_param_as_rvalue( param[0] ) );

    gcc_jit_block_add_assignment( block, NULL, src_val, gcc_jit_param_as_rvalue( param[1] ) );

    gcc_jit_block_add_assignment( block, NULL, index_val, gcc_jit_param_as_rvalue( param[2] ) );

    gcc_jit_block_add_assignment( block, NULL, disp_val, gcc_jit_param_as_rvalue( param[3] ) );

    gcc_jit_block_add_assignment( block, NULL, maxdata_val, gcc_jit_param_as_rvalue( param[4] ) );


    gcc_jit_lvalue *dst_val = gcc_jit_context_new_array_access( ctxt, NULL, dst_input,

                                  gcc_jit_context_new_rvalue_from_int( ctxt, int_type, 0 ) ),

                   *index = gcc_jit_context_new_array_access( ctxt, NULL, index_val,

                                   gcc_jit_context_new_rvalue_from_int( ctxt, int_type, 0 ) ),

                   *disp = gcc_jit_context_new_array_access( ctxt, NULL, disp_val,

                               gcc_jit_context_new_rvalue_from_int( ctxt, int_type, 0 ) ),

                   *maxdata = gcc_jit_context_new_array_access( ctxt, NULL, maxdata_val,

                                  gcc_jit_context_new_rvalue_from_int( ctxt, int_type, 0 ) );


    gcc_jit_lvalue *count_val = gcc_jit_function_new_local( func, NULL, int_type, "elem_count" );


    gcc_jit_block *elem_block[desc_used],

                  *elem_exit_block[desc_used];

    int blockn = 0,

        nelem = 0;

    for( int i = 0; i <= desc_used; i++ ){

            char block_name[10];

            elem_block[nelem] = gcc_jit_function_new_block( func, itoa( blockn++, block_name, 10 ) );

            nelem++;

    }


    gcc_jit_block_end_with_jump( block, NULL, elem_block[index] );

The error from compiler is

error: array subscript is not an integer

 1183 |     gcc_jit_block_end_with_jump( block, NULL, elem_block[index] );

Thank you
