New description:
A recent commit d5c4d46a62ce6a0cfa6440344f707136eff18119 which adds a
second pass of CmmCommonBlockElim is observed to conflict with
GhcEnableTablesNextToCode=NO. When building stage2, ghc will produce an
"Each block should be reachable from only one ProcPoint" error and panic.
Original description below:
I'm compiling a recent commit (0017a7b618353bf984d701f6d8ee2810a425e5b3),
yet ghc always panics when ghc-stage1 is compiling ghc-prim. The error is
as follows:

I'm using the following build.mk for those builds here:
{{{
GhcEnableTablesNextToCode = NO
INTEGER_LIBRARY = integer-simple
SRC_HC_OPTS = -O -H64m
GhcStage1HcOpts = -O
GhcStage2HcOpts = -O2
GhcLibHcOpts = -O2
BUILD_PROF_LIBS = YES
SplitObjs = YES
SplitSections = NO
BUILD_SPHINX_HTML = YES
BUILD_SPHINX_PDF = NO
HADDOCK_DOCS = YES
EXTRA_HADDOCK_OPTS += --quickjump --hyperlinked-source
}}}
Still working to figure out a minimal combination of the build flags to
trigger a similar error. Meanwhile, has anyone seen a similar error for a
different commit/platform/build config?
