Abstract
Computer systems and associated methods are disclosed for performing custom code transformations using a compiler that does not support the custom transformations. In embodiments, a wrapper program intercepts a command to the compiler. The wrapper program generates intermediate code using the compiler in accordance with the command. The wrapper program then performs the code transformations on the intermediate code using a code transformer, for example, by performing a search and replace operation to replace particular code sequences in the intermediate code. The wrapper program then generates the binary code from the transformed intermediate code in accordance with the command. In this manner, software may be compiled with the custom code transformations without extensive changes to the source code or the compiler. In one application, the technique may be used to build a hot patch that applies a security update to a software using the software's original compiler.
