            Bug ID: 60743
           Summary: build/genautomata uses 700 MB memory for ARM
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: bernd.edlinger at hotmail dot de

build/genautomata ../../gcc-4.9-trunk/gcc/config/arm/arm.md \
          insn-conditions.md > tmp-automata.c

=> uses way too much memory/takes too long to complete.

this was observed, when building a cross compiler for arm-linux-gnueabi
on a i686-pc-linux-gnu system.

This build-step used significantly less memory in the past.
