Branch Target Injection – "Return Trampoline" Method

Another mitigation method is the concept of "return trampoline," said Intel. This method uses a code sequence to replace indirect branches with a Return instruction, causing the speculative execution to "bounce" so that select binary files are protected from Spectre-powered attacks.

"Intel has worked with the various open source compilers to ensure support for the return trampoline, and with the OS vendors to ensure support for these techniques," said the white paper.
