Hi,
According to the C++ standard ยง17.4.3.4(2,3) the global new and delete
operator implementation can be replaced by the program. For example,
tcmalloc does redefine them. On ELF targets, it is currently OK if you
link libstc++ dynamically. However, if you try to link both tcmalloc
and stdc++

This patch fixes a bug in the vectorized pointer arithmetic in the forwprop

Although it seems to be impossible to create a vector of pointers with the

A few generated files were not mentioned in the generated_files

This changes the handling of SHLIB so that it is inlined into
DRIVER_DEFINES. This is ok because SHLIB is defined in a Makefile
fragment that is included by the generated Makefile.
The rationale for this is that it simplifies some .o targets, so that
we can share more code.

There is an order-only dependency in gcc/Makefile.in that tries to
build the generated files before compiling regular objects. However,
this appears too early, and so at the time it is seen by make,
GCOV_OBJS and GCOV_DUMP_OBJS have not yet been set.
This patch fixes the problem and prevents any

C_TREE_H. This is needed to avoid breaking this build with this
patch.
* Makefile.in (C_TREE_H): Reference c/c-tree.h.
* Make-lang.in (c/gccspec.o): Remove.
This adds the configury needed for automatic dependency tracking. It
also adds some bits to the Makefile so we can begin converting

This converts the ObjC front end.
Note that there is a latent possible bug in this code -- both ObjC and
ObjC++ define START_HDRS. Whichever is included last, wins; if they

eliminated by this series.

This also fixes a latent buglet in lto/Make-lang.in. lto_OBJS should
hold all the objects for a language, but LTO never defined this.
