I've been unable to bootstrap llvm-gcc-4.0 or -4.2 for x86_64
for some weeks now. The current problem is this:

This is from the latest trunk. Is anyone else seeing this problem?

Can you add a - emit-llvm to the xgcc line and generate a reproducible test case? Please file a bugzilla report.

Could this be the problem? (iirc, it wants you to use eax = LEA rsi, rdi) -Chris>> I also see warnings like this: >> >> [x86_64-mod-dbg]: ./xgcc -B./ >> -B/install.modified.debug/x86_64-unknown-linux-gnu/x86_64-unknown- >> linux-gnu/bin/ >> -isystem /install.modified.debug/x86_64-unknown-linux-gnu/x86_64- >> unknown-linux-gnu/include >> -isystem /install.modified.debug/x86_64-unknown-linux-gnu/x86_64- >> unknown-linux-gnu/sys-include >> -L/tmp/ptmp/dag/build.llvm-gcc-4.0.modified.debug/x86_64-unknown- >> linux-gnu/gcc/../ld >> -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes >> -Wmissing-prototypes -Wold-style-definition -isystem ./include - >> fPIC -g >> -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -I. -I. >> -I/llvm-project.modified/llvm-gcc-4.0/trunk/gcc >> -I/llvm-project.modified/llvm-gcc-4.0/trunk/gcc/. >> -I/llvm-project.modified/llvm-gcc-4.0/trunk/gcc/../include >> -I/llvm-project.modified/llvm-gcc-4.0/trunk/gcc/../libcpp/include >> -I/llvm-project.modified/llvm/trunk/include >> -I/ptmp/dag/build.llvm.modified.debug/x86_64-unknown-linux-gnu/include >> -DL_absvdi2 -c /llvm-project.modified/llvm-gcc-4.0/trunk/gcc/ >> libgcc2.c -o >> libgcc/./_absvdi2.o >> [x86_64-mod-dbg]: WARNING: 128-bit integers not supported! >> >> This is from the latest trunk.
