Tejas 1.5 has now been released with important bug fixes.

We had a big issue with dynamic executables (post Linux kernel version 4.4). We were not able to simulate arithmetic instructions because we were not getting them from PIN.

This was happening because the loader was changing the starting address of the text section. This issue has been fixed in the current release. Tejas should now be able to simulate dynamically linked executables. Of course, it will still not be able to simulate the instructions in the libraries (DLLs or shared objects) but the instructions in the main program will be simulated.
