A computer readable medium comprising instructions which, when executed by one or more hardware processors, causes performance of operations comprising: identifying a first virtual machine instruction generated during a code compilation process, the first virtual machine instruction comprising a particular operation operating on a first set of one or more parameters, wherein one or more first parameter types of the first set of one or more parameters are referenced by the first virtual machine instruction itself or are deductible by a virtual machine from previously executed instructions; determining whether there is information, stored external to and in association with the first virtual machine instruction, that references one or more parameter types of the first set of one or more parameters for overriding the one or more first parameter types of the first set of one or more parameters; responsive to determining that there is no information for overriding the one or more first parameter types of the first set of one or more parameters, processing the first virtual machine instruction based on the one or more first parameter types; identifying a second virtual machine instruction generated during the code compilation process, the second virtual machine instruction comprising the particular operation operating on a second set of one or more parameters, wherein one or more second parameter types of the second set of one or more parameters are referenced by the second virtual machine instruction itself or are deductible by the virtual machine from previously executed instructions; determining whether there is information, stored external to and in association with the second virtual machine instruction, that references one or more third parameter types of the second set of one or more parameters for overriding the one or more second parameter types of the second set of one or more parameters; and responsive to determining that there is information for overriding the one or more second parameter types of the second set of one or more parameters, processing the second virtual machine instruction based on the one or more third parameter types referenced by the information. identifying a first virtual machine instruction generated during a code compilation process, the first virtual machine instruction comprising a particular operation operating on a first set of one or more parameters, wherein one or more first parameter types of the first set of one or more parameters are referenced by the first virtual machine instruction itself or are deductible by a virtual machine from previously executed instructions; determining whether there is information, stored external to and in association with the first virtual machine instruction, that references one or more parameter types of the first set of one or more parameters for overriding the one or more first parameter types of the first set of one or more parameters; responsive to determining that there is no information for overriding the one or more first parameter types of the first set of one or more parameters, processing the first virtual machine instruction based on the one or more first parameter types; identifying a second virtual machine instruction generated during the code compilation process, the second virtual machine instruction comprising the particular operation operating on a second set of one or more parameters, wherein one or more second parameter types of the second set of one or more parameters are referenced by the second virtual machine instruction itself or are deductible by the virtual machine from previously executed instructions; determining whether there is information, stored external to and in association with the second virtual machine instruction, that references one or more third parameter types of the second set of one or more parameters for overriding the one or more second parameter types of the second set of one or more parameters; and responsive to determining that there is information for overriding the one or more second parameter types of the second set of one or more parameters, processing the second virtual machine instruction based on the one or more third parameter types referenced by the information.
