After editing src/assembler.c, run "lua etc/assembler-trees.lua" and this file will be edited automatically. This is the first example of a binary tree in this code, so let's explore them in general. The format of a tree node in memory is: left-node* right-node* node-key-cstring binary-data and the general algorithm is to compare the key you're looking for against node-key-cstring, and move to the node pointed to by left-node* or right-node* if the keys don't match. If your key sorts earlier than use left-node*, otherwise go to right-node*. When you find a node that matches your key, traverse-bintree gives you a pointer to the binary-data straight after the node-key-cstring. This data can contain anything you want: fixed length fields, executable code... in this case of this opcode tree, we store nothing. traverse-bintree is passed the maximum length of node-key-cstring, not including the zero, so the zero can be omitted if the string is at that maximum length. If the key isn't present in the tree, you'll eventually get to a node where the left-node* or right-node* pointer you'll need to follow is null (0000). traverse-bintree will give you the location of that pointer, so if you want to insert another node, you can write it to the heap and overwrite the pointer with the new node's location. This approach works even if the tree is completely empty and the pointer you've provided to the root node is null, since that pointer gets updated to point to the first node without needing any special logic. The ordering of nodes in memory is totally arbitrary, so for pre- prepared trees like this one we can have our own meaning for the order of the nodes. By ordering the opcodes by their byte value, we can find the byte by subtracting $asm from the binary-data pointer and dividing by seven (the size of each node). By multiplying the byte value by seven and adding to $disasm, we get the opcode name when disassembling too. ) $tree .$op-lth ( opcode tree ) $start $op-brk .$op-add .$op-dup $disasm [ BRK ] $asm $op-nop .$op-mul .$op-ovr [ NOP ] $op-lit [ 0000 ] [ 0000 ] [ LIT ] $op-pop [ 0000 ] [ 0000 ] [ POP ] $op-dup .$op-div .$op-eor [ DUP ] $op-swp [ 0000 ] [ 0000 ] [ SWP ] $op-ovr .$op-ora .$op-pek [ OVR ] $op-rot .$op-pop .$op-sft [ ROT ] $op-equ .$op-brk .$op-jnz [ EQU ] $op-neq [ 0000 ] [ 0000 ] [ NEQ ] $op-gth [ 0000 ] [ 0000 ] [ GTH ] $op-lth .$op-equ .$op-pok [ LTH ] $op-gts .$op-gth .$op-jmp [ GTS ] $op-lts [ 0000 ] [ 0000 ] [ LTS ] [ 0000 ] [ 0000 ] [ ??? ] [ 0000 ] [ 0000 ] [ ??? ] $op-pek [ 0000 ] [ 0000 ] [ PEK ] $op-pok .$op-nop .$op-sth [ POK ] $op-ldr .$op-jsr .$op-lit [ LDR ] $op-str [ 0000 ] [ 0000 ] [ STR ] $op-jmp [ 0000 ] [ 0000 ] [ JMP ] $op-jnz .$op-gts .$op-ldr [ JNZ ] $op-jsr [ 0000 ] [ 0000 ] [ JSR ] $op-sth .$op-rot .$op-sub [ STH ] $op-add [ 0000 ] .$op-and [ ADD ] $op-sub .$op-str .$op-swp [ SUB ] $op-mul .$op-lts .$op-neq [ MUL ] $op-div [ 0000 ] [ 0000 ] [ DIV ] $op-and [ 0000 ] [ 0000 ] [ AND ] $op-ora [ 0000 ] [ 0000 ] [ ORA ] $op-eor [ 0000 ] [ 0000 ] [ EOR ] $op-sft [ 0000 ] [ 0000 ] [ SFT ] @state-machine-pointers ( normal mode 00 ) .normal-root .normal-main ( macro definition 01 ) .macro-root .macro-main ( macro definition, contents ignored 02 ) .macro-root .ignore ( variable definition, expect field size 04 ) .variable-nul .variable-size ( variable definition, expect field name 08 ) .variable-root .variable-name ( reserved for future use 10 ) [ 0000 ] .ignore ( literal data 20 ) .normal-] .data-main ( reserved for future use 40 ) [ 0000 ] .ignore ( comment 80 ) .normal-) .ignore ( Next up, we have the tree of code corresponding to each token's first character.
