------- 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.
