History

Oren Ben Simhon fa582b075c Control-Flow Enforcement Technology - Shadow Stack support (LLVM side) Shadow stack solution introduces a new stack for return addresses only. The HW has a Shadow Stack Pointer (SSP) that points to the next return address. If we return to a different address, an exception is triggered. The shadow stack is managed using a series of intrinsics that are introduced in this patch as well as the new register (SSP). The intrinsics are mapped to new instruction set that implements CET mechanism. The patch also includes initial infrastructure support for IBT.

README

This directory contains tests for the MIR file format parser and printer. It
was necessary to split the tests across different targets as no single target
covers all features available in machine IR.

Tests for codegen passes should NOT be here but in test/CodeGen/sometarget. As
a rule of thumb this directory should only contain tests using
'llc -run-pass none'.
