10 | // This file defines the function verifier interface, that can be used for some | |||||
11 | // sanity checking of input to the system. | |||||
12 | // | |||||

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... | |||||
