We need to ensure that StackSlotColoring.cpp does not reuse stack spill slots in functions that call "returns_twice" functions such as setjmp(), otherwise this can lead to miscompiled code, because a stack slot would be clobbered when it's still live. This was already handled correctly for functions that call setjmp() (though this wasn't covered by a test), but not for functions that invoke setjmp(). We fix this by changing callsFunctionThatReturnsTwice() to check for invoke instructions. This fixes PR18244. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199180 91177308-0d34-0410-b5e6-96231b3b80d8 |
