[Bug target/28193] config/arm/arm.c:3140 ICE
--- 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. make[8]: Entering directory `/home/sjackman/src/toolchain/src/_build/arm-elf/thumb/pic/xip/newlib/libc/stdio' arm-elf-gcc -B/home/sjackman/src/toolchain/src/_build/arm-elf/newlib/ -isystem /home/sjackman/src/toolchain/src/_build/arm-elf/newlib/targ-include -isystem /home/sjackman/src/toolchain/src/newlib/libc/include -DPACKAGE_NAME=\newlib\ -DPACKAGE_TARNAME=\newlib\ -DPACKAGE_VERSION=\1.14.0\ -DPACKAGE_STRING=\newlib\1.14.0\ -DPACKAGE_BUGREPORT=\\ -I. -I../../../../../../../../newlib/libc/stdio -O2 -D__NO_SYSCALLS__ -DNO_FLOATING_POINT -DHAVE_FCNTL -DHAVE_NANOSLEEP -fno-builtin -O2 -g -O2 -mthumb -fPIC -msingle-pic-base -c -o lib_a-findfp.o `test -f 'findfp.c' || echo '../../../../../../../../newlib/libc/stdio/'`findfp.c ../../../../../../../../newlib/libc/stdio/findfp.c: In function 'std': ../../../../../../../../newlib/libc/stdio/findfp.c:61: internal compiler error:in thumb_find_work_register, at config/arm/arm.c:3173 Please submit a full bug report, with preprocessed source if appropriate.

--- Comment #3 from sjackman at gmail dot com 2006-06-28 20:51 --- I tried backporting thumb_compute_save_reg_mask from GCC 4.1.1 to GCC 4.0.3 without success. I'll try backporting this entire patch from svn. 2005-03-01 Nick Clifton [EMAIL PROTECTED] * config/arm/arm.c (thumb_find_work_register): Check all of the argument registers to see if they are free, and a couple of special cases where the last argument register but can be proved to be available during the function's prologue. (print_multi_reg, arm_compute_save_reg0_reg12_mask, output_return_instruction, emit_multi_reg_push, thumb_pushpop, thumb_unexpanded_epilogue): Use unsigned long as the type for the register bit-mask. (thumb_compute_save_reg_mask): Likewise. Also use thumb_find_work_register() to ensure that there is agreement about which work register is going to be used in the prologue. (thumb_output_function_prologue): Use unsigned long as the type for the register bit-mask. Also delay pushing the link register if other high registers are going to be pushed. (thumb_compute_save_reg_mask, emit_multi_reg_push, print_multi-reg, number_of_first_bit_set, thumb_pushpop): Remove redundant prototypes. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28193

--- Comment #4 from sjackman at gmail dot com 2006-06-28 22:30 --- I tried applying r95736 (2005-03-01 Nick Clifton) and r103151 (2005-08-16 Richard Earnshaw) against GCC 4.0.3. Both these patches apply cleanly (with offsets), but don't fix the problem compiling newlib. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28193
