It looks like m_graph.m_form is modified mid-way through the DCEPhase. I did + GraphForm originalForm = m_graph.m_form; if (m_graph.m_form == SSA) { // Need to process the graph in reverse DFS order, so that we get to the uses // of a node before we get to the node itself. Vector<BasicBlock*> depthFirst; m_graph.getBlocksInDepthFirstOrder(depthFirst); - for (unsigned i = depthFirst.size(); i--;) + for (unsigned i = depthFirst.size(); i--;) { fixupBlock(depthFirst[i]); + ASSERT(originalForm == m_graph.m_form); + } } else { RELEASE_ASSERT(m_graph.m_form == ThreadedCPS); - for (BlockIndex blockIndex = 0; blockIndex < m_graph.numBlocks(); ++blockIndex) + for (BlockIndex blockIndex = 0; blockIndex < m_graph.numBlocks(); ++blockIndex) { fixupBlock(m_graph.block(blockIndex)); + ASSERT(originalForm == m_graph.m_form); + } cleanVariables(m_graph.m_arguments); And I'm seeing this assertion being hit. Upon some investigation this is triggered by m_graph.dethread() added in the patch for the bug 130069.

Upon some investigation this is triggered by m_graph.dethread() added in the patch for the bug 130069. Thanks for finding this. I will fix the other patch before landing and add a test. We don't need this bug since this bug doesn't apply to ToT.

Yup.
