Cleaning the stack by filtering the assembly

Published: Oct 6 2014

In order to help the SimGridMC state comparison code, I wrote a proof-of-concept LLVM pass which cleans each stack frame before using it. However, SimGridMC currently does not work properly when compiled with clang/LLVM. We can do the same thing by pre-processing the assembly generated by the compiler before passing it to the linker: this is done by inserting a script between the compiler and the assembler. This script will rewrite the generated assembly by prepending stack-cleaning code at the beginning of each function.
