Subject: [PING][PATCH]: Fix PR rtl-optimization/29841: cfgbuild.c: control_flow_insn_p () .

REPOST with CC to gcc-patches@gcc.gnu.org . Sorry for inconvenience.

Hi,

This is a ping for patch at
http://gcc.gnu.org/ml/gcc-patches/2007-01/msg01220.html

Hi,

This patch was proposed by Jan Hubicka but wasn't committed because of some unknown reason. I bootstrapped/regtested it on x86-64 and took the liberty of submitting it here.
The patch forces any insn that has a barrier after it be control_flow_insn_p thus making it impossible for barrier to appear inside basic block.  An example of such insn is
(insn (trap_if (const_int 1))) on i586-pc-linux-gnu.
Jan, can you please check in the patch?

Thanks,

Maxim
