| 9 | // This file defines the function verifier interface, that can be used for some | ||||
| 10 | // sanity checking of input to the system. | ||||
| 11 | // | ||||
| 12 | // Note that this does not provide full `Java style' security and verifications, | ||||
| 13 | // instead it just tries to ensure that code is well-formed. | ||||
| 14 | // | ||||
| 15 | // * Both of a binary operator's parameters are of the same type | ||||
| 16 | // * Verify that the indices of mem access instructions match other operands | ||||
| 17 | // * Verify that arithmetic and other things are only performed on first-class | ||||
| 18 | // types. Verify that shifts & logicals only happen on integrals f.e. | ||||
| 19 | // * All of the constants in a switch statement are of the correct type | ||||
| 20 | // * The code is in valid SSA form | ||||
| 21 | // * It should be illegal to put a label into any other type (like a structure) | ||||
| 22 | // or to return one. [except constant arrays!] | ||||
| 23 | // * Only phi nodes can be self referential: 'add i32 %0, %0 ; <int>:0' is bad | ||||
| 24 | // * PHI nodes must have an entry for each predecessor, with no extras. | ||||
| 25 | // * PHI nodes must be the first thing in a basic block, all grouped together | ||||
| 26 | // * PHI nodes must have at least one entry | ||||
| 27 | // * All basic blocks should only end with terminator insts, not contain them | ||||
| 28 | // * The entry node to a function must not have predecessors | ||||
| 29 | // * All Instructions must be embedded into a basic block | ||||
| 30 | // * Functions cannot take a void-typed parameter | ||||
| 31 | // * Verify that a function's argument list agrees with it's declared type. | ||||
| 32 | // * It is illegal to specify a name for a void value. | ||||
| 33 | // * It is illegal to have a internal global value with no initializer | ||||
| 34 | // * It is illegal to have a ret instruction that returns a value that does not | ||||
| 35 | // agree with the function return value type. | ||||
| 36 | // * Function call argument types match the function prototype | ||||
| 37 | // * A landing pad is defined by a landingpad instruction, and can be jumped to | ||||
| 38 | // only by the unwind edge of an invoke instruction. | ||||
| 39 | // * A landingpad instruction must be the first non-PHI instruction in the | ||||
| 40 | // block. | ||||
| 41 | // * Landingpad instructions must be in a function with a personality function. | ||||
| 42 | // * All other things that are tested by asserts spread about the code... | ||||
