Re: can't bootstrap current trunk: internal compiler error: in simplify_subreg,@simplify-rtx.c:4679
Hello,
the bootstrap failure you are seeing is caused by my decompose
multiword shift patch:
http://gcc.gnu.org/ml/gcc-patches/2007-08/msg00419.html
It is the same failure as reported by Andreas Tobler:
http://gcc.gnu.org/ml/gcc-patches/2007-08/msg00533.html
I don't have access to a sparc machine. Could you please test the
following patch?
The patch at least seems to fix it on a cross gcc.
Bye,
-Andreas-

Your patch does not fix it for me. It moves the error to another line: .../libgcc/../gcc/libgcc2.c: In function '__fixunssfdi': .../libgcc/../gcc/libgcc2.c:1348: internal compiler error: in simplify_subreg, at simplify-rtx.c:4674 Try: cc1 -fpreprocessed libgcc2.i -quiet -dumpbase libgcc2.c -mcpu=v9 -auxbase-strip _fixunssfdi.o -g -g -g -O2 -O2 -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -version -fkeep-inline-functions -fPIC -o libgcc2.s Thanks, --Kaveh -- Kaveh R.
