...s functionality has been moved to the opt tool. This was requested in PR872. The change reduces LLVM's Debug footprint by 36MB without any loss of functionality. To obtain analyze's old functionality, pass the -analyze switch to the opt tool. If you previously did this: analyze $FNAME -domset -disable-verify you would now do this: opt -analyze $FNAME -domset -disable-verify Pretty simple. Reid.

This was indeed a memory issue - the hard datasize limit on my freebsd box was 512 mb and this opt went over. Increasing hard limit fixed the problem. However, most unices have a 512mb limit - maybe insanely huge functions as this one should be automagically split somewhere?

After running through bugpoint, I get this reduced function You can reproduce the problem with: opt bugpoint-reduced-function.bc -break-crit-edges -adce -verify Bugpoint is currently trying to narrow down which block breaks this, but is so far failing. It seems to be running out of memory rather than failing on a particular block. This is on freebsd 5.4, X86, llvm is compiled with gcc 3.4.2

Several nasty sources of non-determinism in the compiler have been eliminated, including these passes: mem2reg, licm, domset, domtree, simplifycfg, inline, scalarevolutions, argpromotion. LLVM IR Size Reduction: 5. We've started to look at reducing the memory footprint of the various LLVM IR classes. The meta-bug PR388 now tracks various ideas for reducing the size of the LLVM IR: http://llvm.cs.uiuc...
