Simplifier failing to unbox join point
A consequence of the recent "silent superclass" patch is that T5113 performance test is failing badly:
=====> T5113(normal) 2794 of 3389 [0, 786, 0] cd ./perf/should_run && '/64playpen/simonmar/nightly/HEAD-cam-04-unx/x86_64-unknown-linux/inplace/bin/ghc-stage2' -fforce-recomp -dcore-lint -dcmm-lint -dno-debug-output -no-user-package-db -rtsopts -fno-ghci-history -o T5113 T5113.hs -O >T5113.comp.stderr 2>&1
cd ./perf/should_run && ./T5113 +RTS -V0 -tT5113.stats --machine-readable -RTS </dev/null >T5113.run.stdout 2>T5113.run.stderr
bytes allocated 822112880 is more than maximum allowed 9000000
*** unexpected failure for T5113(normal)My preliminary diagnosis is that it was only working nicely before by a fluke, and there's a problem here we must look at. In effect, because of a join point we are getting boxing and unboxing in an inner loop.
