LLVM Adds Additional Protections For Arm's SLS Speculation Vulnerability Mitigation

Revealed earlier this year was the Arm Straight Line Speculation (SLS) vulnerability. SLS was a Google discovery for modern ARMv8 CPUs where speculative execution past unconditional changes in control flow could lead to information disclosure via side-channel analysis. Arm recommended compiler-based mitigations to insert speculation barriers after vulnerable instructions, which GCC and LLVM began adding opt-in protections right away. This weekend some additional SLS functionality was added for LLVM.

Arm Backporting SLS Vulnerability Mitigation To Existing GCC Releases

Back in June when Arm disclosed their Straight Line Speculation (SLS) vulnerability affecting their modern ARM processor designs there wasn't a whole lot of attention. It seems SLS is serious enough that Arm is working on bringing their compiler-based mitigations to existing GCC releases beyond it already being in the current development code.
