             Bug #: 54490
           Summary: ICE: Spill failure in newlib build
    Classification: Unclassified
           Product: gcc
           Version: 4.7.1
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code, ra
          Severity: major
          Priority: P3
         Component: other
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: gjl@gcc.gnu.org
            Target: avr


../../gcc.gnu.org/gcc-4_7-branch/configure --target=avr
--prefix=/local/gnu/install/gcc-4.7 --disable-nls --with-dwarf2
--enable-languages=c,c++ --enable-target-optspace=yes --enable-checking=rtl,yes

For this configure, the build aborts with a spill fail ICE if newlib is in the
source path.  SVN is from today's (2012-09-05) gcc-4_7-branch

Reducing importance. I don't know of anyone building toolchains with the avr
target and using newlib as the C library. The avr-rtems target should be tried,
though.

I see hundreds of spill fails riunning the test suite -- with AVR-Libc.  Some
months ago, 2 or 3 pathological test cases failes with spill fails.  Now there
are hundreds of fails for simple test cases...

Still happening but on a different file. Preprocessed source attached.

xgcc (GCC) 4.8.0 20121103 (experimental) [trunk revision 193124]

Short command to go with preprocessed source:



/home/joel/v850/tools/b-gcc-svn-avr-rtems4.11/./gcc/xgcc
-B/home/joel/v850/tools/b-gcc-svn-avr-rtems4.11/./gcc/ -mmcu=avr25  -Os 
-mcall-prologues  -Wall -fno-builtin      -g -O2 -c t.c

Fails similarly at -O2 and -Os. Works at -O0.
