GCC trunk gets an internal compiler error when building SPEC CPU2000 test
416.gamess with "-O2 -fselective-scheduling2 -fsel-sched-pipelining
-funroll-all-loops" on powerpc64-linux, as demonstrated by a minimized testcase
that I'll attach to this PR.

The ICE occurs with a compiler built for powerpc64-linux but only for -m32 (the
default for my compiler), not for -m64. It does not occur for a powerpc-linux
compiler.

Also not reproducible on x86_64->ppc64 cross.
While codegen differences on ppc/ppc64/x86_64 cross are certainly surprising,
in the end this testcase most likely indicates a bug in sel-sched.

Reprodicible on x86_64->ppc64 cross with -fno-section-anchors appended to
command line. Native ppc64 compiler seems to not use section anchors on this
testcase.

The testcase with the options shown in the submitter's description compiles
cleanly with the current 4.4 branch and with GCC 4.4.1.

------- Comment #7 from abel at gcc dot gnu dot org 2009-12-24 08:18 -------
The problem here is in the incorrect handling of the transformation history.
When an insn is transformed (i.e. substituted/speculated), this is recorded so
that the insn could be found during upward code motion. Part of the data
recorded is the uid of insn on which the transformation happened. As this
second insn could get removed while filling a parallel group, and its
bookkeeping copy could be created, we need to undo the transformation while
moving through this copy instead of original insn. To do this, we also
maintain a bitmap of insn uids that could generate the copy (INSN_ORIGINATORS),
and we also check it on the copies. The actual bug was that the bitmap should
contain all "ancestor insns" of a copy, not only "parents", as the copy found
could originated from another copy (yes, I was stupid of not thinking about
this earlier). The alternate solution would be to make the search function
recurse on INSN_ORIGINATORS bitmap, but this one seemed clearer.
Patch by Alexander below, we would need to ask someone with access to ppc64 to
test it (as a part of combined patch fixing other sel-sched bugs) in addition
to our testing.
* sel-sched-ir.h (struct _sel_insn_data): Update comment.
* sel-sched.c (move_exprs_to_boundary): Transitively add all
originators' originators.

* sel-sched.c (try_replace_dest_reg): When chosen register

still check all original insns for validity of replacing destination
register. Set EXPR_TARGET_AVAILABLE to 1 before leaving function
in this case.
