From svn r119726 (Sun, 10 Dec 2006) I am getting an ICE during
bootstrap on mipsel-linux. This is a new failure since Wed Dec 6
06:34:07 UTC 2006 (revision 119575) which bootstrapped and tested just
fine. I don't really want to do a regression hunt as bootstraps take 3
or 4 days for me. I will update and try it again.
Configured as: ../gcc/configure --with-arch=mips32 --with-float=soft
--disable-java-awt --without-x --disable-tls --enable-__cxa_atexit
--disable-jvmpi --disable-static --disable-libmudflap
--enable-languages=c,c++,java
The bootstrap compiler is GCC-4.0.2
In stage 2 (i.e. with the stage 1 compiler) I get an ICE:
