However, this bug seems to have been the cause of #7192, because the graph-colouring allocator is more sensitive to having correct liveness information on jumps. compiler/cmm/CmmCallConv.hs | 6 +++--- compiler/cmm/CmmParse.y | 2 +- compiler/cmm/MkGraph.hs | 32 ++++++++------------------------ compiler/codeGen/StgCmmBind.hs | 21 +++++++++++---------- compiler/codeGen/StgCmmExpr.hs | 4 ++-- compiler/codeGen/StgCmmHeap.hs | 12 ++++-------- compiler/codeGen/StgCmmLayout.hs | 2 +- 7 files changed, 30 insertions(+), 49 deletions(-) Diff suppressed because of size.
