2011-10-15Fix indvars randomness by removing iteration over a map.Andrew Trick
I rewrote the algorithm a while back so it doesn't require map lookup, but neglected to change the data structure. This was caught by llvm-gcc self host, not because there's anything special about llvm-gcc, but because it is the only test for nondeterminism we currently have. Unit tests don't work well for everything; we should always try to have a nondeterminism stress test running.

2011-10-15Mark tADDrSPi as having side effects again.Jakob Stoklund Olesen
It really doesn't, but when r141929 removed the hasSideEffects flag from this instruction, it caused miscompilations. I am guessing that it got moved across a stack pointer update. Also clear isRematerializable after checking that this instruction is in fact never rematerialized in the nightly test suite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142030 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-15Thumb1 does not support dynamic stack realignment.Chad Rosier
rdar://10288916 is tracking this fix. In the past, instcombine and other passes were promoting alloca alignment past the natural alignment, resulting in dynamic stack realignment. Lang's work now prevents this from happening (LLVM commit r141599).
