65 /* analyse_stack uses the intermediate code created by parse.c to
66 * build a model of the JVM operand stack for the current method.
68 * The following checks are performed:
69 * - check for operand stack underflow (before each instruction)
70 * - check for operand stack overflow (after[1] each instruction)
71 * - check for matching stack depth at merging points
72 * - check for matching basic types[2] at merging points
73 * - check basic types for instruction input (except for BUILTIN*
74 * opcodes, INVOKE* opcodes and MULTIANEWARRAY)
76 * [1]) Checking this after the instruction should be ok. parse.c
77 * counts the number of required stack slots in such a way that it is
78 * only vital that we don't exceed `maxstack` at basic block
81 * [2]) 'basic types' means the distinction between INT, LONG, FLOAT,
82 * DOUBLE and ADDRESS types. Subtypes of INT and different ADDRESS
83 * types are not discerned.
