On my Linux/x86-64 system using --enable-checking=yes,rtl, I get a bootstrap
failure since revision 144100 - revision was good 144099.

+ * config/i386/i386.md (UNSPEC_MEMORY_BLOCKAGE): New constant.
+ (memory_blockage): New expander.
+ (*memory_blockage): New insn pattern.
+ * config/i386/i386.c (ix86_expand_prologue): Use memory_blockage
+ instead of general blockage at the end of function prologue when
+ frame pointer is used to access red zone area. Do not emit blockage
+ when profiling, it is emitted in generic code.
+ (ix86_expand_epilogue): Emit memory_blockage at the beginning of
+ function epilogue when frame pointer is used to access red zone area.

Compiler was bootstrapped with:
/cvs/gcc-svn/trunk/configure --prefix=/opt/gcc/4.4-devel
--enable-checking=yes,rtl --enable-decimal-float --enable-threads=posix
--enable-clocale=gnu --enable-ssp --disable-libssp
--enable-libstdcxx-allocator=new --enable-__cxa_atexit --enable-shared
--enable-languages=c,c++ --disable-multilib --with-system-zlib

Note: If you use --disable-checking, the bootstrap is successfull
