* Fix indvars randomness by removing iteration over a map.Andrew Trick2011-10-151-12/+12
| | | | | | | | | | | | | | 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. Fixes PR11133: llvm-gcc self host .o mismatch after enable-iv-rewrite=false git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142036 91177308-0d34-0410-b5e6-96231b3b80d8
* Clear out the landing pad to call site map for each function.Bill Wendling2011-10-151-0/+1
| | | | | | | | This isn't put into the 'clear()' method because the information needs to stick around (at least for a little bit) after the selection DAG is built. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142032 91177308-0d34-0410-b5e6-96231b3b80d8
* Mark tADDrSPi as having side effects again.Jakob Stoklund Olesen2011-10-151-3/+3
| | | | | | | | | | | 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

* Thumb1 does not support dynamic stack realignment.Chad Rosier2011-10-151-0/+5
| | | | | | | | | | | 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). Now that this really shouldn't happen report a fatal error rather than silently generate bad code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142028 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | TableGen will mark any pattern-less instruction as having unmodeled side effects. This is extra bad for V_SET0 which gets rematerialized a lot.

* Add value numbers when spilling dead defs.Jakob Stoklund Olesen2011-10-142-1/+28
| | | | | | | | | | | | | | | | When spilling around an instruction with a dead def, remember to add a value number for the def. The missing value number wouldn't normally create problems since there would be an incoming live range as well. However, due to another bug we could spill a dead V_SET0 instruction which doesn't read any values. The missing value number caused an empty live range to be created which is dangerous since it doesn't interfere with anything. This fixes part of PR11125. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141923 91177308-0d34-0410-b5e6-96231b3b80d8
