[Bug c/41798] New: internal compiler error: in expand_scalar_variables_expr, at graphite.c:4295

[ronis at ronispc dot chem dot mcgill dot ca]

I'm building the git master of mesa on an i686-linux-gnu box (basically
slackware 12.2) using 
gcc configured/built with 

gcc -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../gcc/configure --host=i686-pc-linux-gnu --prefix=/usr
--with-gnu-as --enable-shared --with-gnu-ld --enable-threads=posix
--with-ecj-jar=/usr/share/java/ecj.jar
--enable-languages=c,c++,fortran,java,objc
Thread model: posix
gcc version 4.4.2 (GCC)

No CFLAGS or CXXFLAGS were set when I built gcc.

Make was building in mesa/progs/redbook when:


/usr/bin/gcc -save-temps -I../../include -march=native -msse2 -mfpmath=sse -O3
-ffast-math -funroll-loops -fomit-frame-pointer -floop-interchange

I'll attach the .i and .s files.

removing -floop- flags hides/removes the problem.

Removes the problem.  graphite.c code is only involved when the -floop-*
options are supplied.

Fixed in the Graphite branch.  I will do a merge back to trunk in the next
days.

Oh, well, this is reported against gcc4.4. 

I do not intend to fix graphite there anymore, as there are way too many
changes to backport.  You should try gcc 4.5 if you intend to use -floop-block.
