--- Comment #202 from John Paul Adrian Glaubitz <glaubitz at physik dot fu-berlin.de> ---
Adding "gcc/gimple-lower-bitint*" to "compare_exclusions" in configure.ac makes
the build pass the bootstrap comparison and completely succeed with LRA enabled
with the following patches applied:

- 58832
- 58833
- 58883
- 58905
- 59000

This is with late-combine disabled which I will enable now for the next test
build.
