[Bug target/28193] config/arm/arm.c:3140 ICE

["sjackman at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #2 from sjackman at gmail dot com  2006-06-28 20:18 -------
This proposed patch does help. At the very least, it prevents the ICE on
compiling crtstuff.c while compiling the toolchain. However, with this patch
applied, I saw the same bug later while compiling newlib. As the comment in
thumb_find_work_register suggests, the real bug is probably in
thumb_compute_save_reg_mask.
