* global.c (build_insn_chain): Include insn that occur between
basic blocks.
Who approved this patch?
However, the reload_insn_chain actually needs the insns that appear
between basic blocks, in particular the labels in front of branch
tables. I added code here to check for insns that may be in front of a
basic block after scanning that block.
There are a lot of ways that I could have done this, for instance, I
could have just written in terms of the PREV_INSN as the old code was.
I think that in doing it the way that i have done it, it is obvious what
needs to be done if someone really does get rid of the branch tables
between the blocks.
Sure, but the code in build_insn_chain is now more convoluted than in the
original version (and twice as big). And, please, fix the formatting.
it was approved by seonbae, a register allocation reviewer.The
reason that it is longer is that it is more precise. The code to
properly handle subregs, as well as properly dealing with registers live
thru insns, accounts for most of the expansion over the old code.
formatting fixes committed as revision 129262.

That is fine, there are no top sets anymore.
the problem is the code that builds the reload insn chain. the new code
uses the cfg and does not add the label or the jump table that lives
between basic blocks to the chain. I will post a patch as soon as my
tests finish.

When I rewrote this code to use backward scanning rather than forwards
scanning, I converted it to properly use the cfg, since it is generally
considered outmoded to just scan the insns.
However, the reload_insn_chain actually needs the insns that appear
between basic blocks, in particular the labels in front of branch
tables. I added code here to check for insns that may be in front of a
basic block after scanning that block.
There are a lot of ways that I could have done this, for instance, I
could have just written in terms of the PREV_INSN as the old code was.
I think that in doing it the way that i have done it, it is obvious what
needs to be done if someone really does get rid of the branch tables
between the blocks.
This has been bootstrapped and regression tested on x86-{64,32} ppc-32,
and ia-64. However it is not clear to me how many platforms use this
kind of table branch. The bug appears to only be on the -march=i586, so
the reviewers may wish to comment on my choice of dg options on the test.
Ok to commit?

--- Comment #11 from ubizjak at gmail dot com 2007-10-10 07:59 --- (In reply to comment #9) Revision 128957 causes this regression. I can confirm that r128956 bootstraps OK when configured with --build=i386-pc-linux-gnu. Also, r128956 compiles and runs testcase from comment #8 without problems. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33676
