Yeah, preprocessed source plus g++ options are needed.
I don't know the libreoffice build system either, as last resort solution you
could try
mkdir ~/bin
cat > ~/bin/g++ <<\EOF
#!/bin/sh
mkdir -p /tmp/cmdlines/ 2>/dev/null
echo cwd is `pwd` cmdline "$@" >> /tmp/cmdlines/$$
exec /usr/bin/g++ "$@"
and run the build under PATH=~/bin:$PATH CXX=~/bin/g++ or so, then just
grep for the source file in question. If you hit it already once, supposedly
another make invocation wouldn't recompile everything, just a few sources and
ICE again.

Genius idea! Unfortunately the preprocessor output skeletoncommon.ii is more
than 2MB and so I can't attach it to this bug. I've put it here
http://benton.eu.com/skeletoncommon.ii
The command that produced it was:

We end up with:
(insn 38 73 40 5 (parallel [
(set (reg/f:SI 7 sp)
(plus:SI (reg/f:SI 7 sp)
(const_int 12 [0xc])))
(clobber (reg:CC 17 flags))
]) pr53602.ii:359 251 {*addsi_1}
(expr_list:REG_UNUSED (reg:CC 17 flags)
(expr_list:REG_ARGS_SIZE (const_int 0 [0])
(nil))))
(insn 40 38 41 5 (parallel [
(set (reg/f:SI 7 sp)
(plus:SI (reg/f:SI 7 sp)
(const_int -12 [0xfffffffffffffff4])))
(clobber (reg:CC 17 flags))
]) pr53602.ii:64 251 {*addsi_1}
(expr_list:REG_UNUSED (reg:CC 17 flags)
(expr_list:REG_ARGS_SIZE (const_int 12 [0xc])
(nil))))
(insn 41 40 42 5 (set (mem/f:SI (pre_dec:SI (reg/f:SI 7 sp)) [0 S4 A32])
(mem/f/c:SI (plus:SI (reg/f:SI 6 bp)
(const_int -12 [0xfffffffffffffff4])) [3 D.3489.pData+0 S4
A32])) pr53602.ii:64 43 {*pushsi2}
(expr_list:REG_ARGS_SIZE (const_int 16 [0x10])
(nil)))
before csa and csa obviously merges the two into sp += 0 that it wants to
delete.
force_move_args_size is called with prev == NULL (as it is at the start of a
bb). But apparently cleanup_cfg at the start of csa pass jump threaded the
call sequence starting at insn 41, so the two stack adjustments that cancel
each other end up the only insns in a bb. So we trigger:
/* ??? We *must* have a place, lest we ICE on the lost adjustment.
Options are: dummy clobber insn, nop, or prevent the removal of
the sp += 0 insn. Defer that decision until we can prove this
can actually happen. */
I guess if we proved that all the predecessors of the bb have the same current
REG_ARGS_SIZE, or all the successor have the same current REG_ARGS_SIZE, we
could avoid the note altogether. Or do one of the things the comment talks
about. Richard, can you please handle this?

Or perhaps just handle this particular case for now, when there has been jump
threading right after the sp adjustment sequence that cancelled each other.
Thus, if we reach end of bb after the insn without seeing a CALL or or throwing
insn and the bb has a single fallthru successor only, keep looking in the
successor bb.
