            Bug ID: 67029
           Summary: gcc-5.2.0 unable to find a register to spill with O3
                    fsched-pressure fschedule-insns
           Product: gcc
           Version: 5.2.0
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---

I'm using gcc-5.2.0 with binutils-2.25 on an amd64 maschine.
While compiling the tor program in version 2.6.10 with CFLAS="-O3
-fsched-pressure -fschedule-insns" I'm hitting following error:

build log of tor-0.2.6.10 with gcc-4.9.3

I wanted to note that this is a regression, the project compiles fine with
gcc-4.9.3 and is seems similar to this bug

--- Comment #9 from vries at gcc dot gnu.org ---
I've done the same build using gcc-5-branch. There, stage2 genpreds also
depends on libstdc++.so.6, but no symbols from it are needed, and no version is
required, so the build doesn't break.

The problem is

/* The value of get_preferred_alternatives for the current instruction,
   supplemental to recog_data.  */
