10// This file defines the function verifier interface, that can be used for some
11// sanity checking of input to the system.
12//
13// Note that this does not provide full `Java style' security and verifications,
14// instead it just tries to ensure that code is well-formed.
15//
16// * Both of a binary operator's parameters are of the same type
17// * Verify that the indices of mem access instructions match other operands
18// * Verify that arithmetic and other things are only performed on first-class
19// types. Verify that shifts & logicals only happen on integrals f.e.
20// * All of the constants in a switch statement are of the correct type
21// * The code is in valid SSA form
22// * It should be illegal to put a label into any other type (like a structure)
23// or to return one. [except constant arrays!]
24// * Only phi nodes can be self referential: 'add i32 %0, %0 ; <int>:0' is bad
25// * PHI nodes must have an entry for each predecessor, with no extras.
26// * PHI nodes must be the first thing in a basic block, all grouped together
27// * PHI nodes must have at least one entry
28// * All basic blocks should only end with terminator insts, not contain them
29// * The entry node to a function must not have predecessors
30// * All Instructions must be embedded into a basic block
31// * Functions cannot take a void-typed parameter
32// * Verify that a function's argument list agrees with it's declared type.
33// * It is illegal to specify a name for a void value.
34// * It is illegal to have a internal global value with no initializer
35// * It is illegal to have a ret instruction that returns a value that does not
36// agree with the function return value type.
37// * Function call argument types match the function prototype
38// * A landing pad is defined by a landingpad instruction, and can be jumped to
39// only by the unwind edge of an invoke instruction.
40// * A landingpad instruction must be the first non-PHI instruction in the
41// block.
42// * Landingpad instructions must be in a function with a personality function.
43// * All other things that are tested by asserts spread about the code...
