| 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... | |||
