on the template class 'vec'.
This patch rewrites the old VEC macro-based interface into a new one
based on the template class 'vec'. The user-visible changes are
described in http://gcc.gnu.org/wiki/cxx-conversion/cxx-vec.
I have tested the patch pretty extensively:
- Regular bootstraps on x86_64, ppc, ia64, sparc and hppa.
- Bootstraps with --enable-checking=release
- Bootstraps with --enable-checking=gc,gcac
- Basic builds on all targets (using contrib/config-list.mk).
We no longer access the vectors via VEC_* macros. The pattern is
"VEC_operation (T, A, V, args)" becomes "V.operation (args)".
The only thing I could not do is create proper ctors and dtors for the
vec class. Since these vectors are stored in unions, we
have to keep them as PODs (C++03 does not allow non-PODs in unions).
This means that creation and destruction must be explicit. There is a
new method vec<type, allocation, layout>::create() and another vec<type,
allocation, layout>::destroy() to allocate the internal vector.
For vectors that must be pointers, there is a family of free functions
that implement the operations that need to tolerate NULL vectors.
These functions all start with the prefix 'vec_safe_'. See the wiki
page for details.
The gengtype change removes the special handling for VEC() that used
to exist in gengtype. Additionally, it allows gengtype to recognize
templates of more than one argument and introduces the concept of an
undefined type (useful for template arguments that may or may not be
types).
When a TYPE_UNDEFINED is reached, gengtype will ignore it if it
happens inside a type marked with GTY((user)). Otherwise, it will
emit an error.
Finally, gengtype rejects root types marked GTY((user)) that are not
first class pointers.

This patch instruments many memory access patterns through builtins.
Basically, for a call like:
__builtin_memset (from, 0, n_bytes);
the patch would only instrument the accesses at the beginning and at
the end of the memory region [from, from + n_bytes]. This is the
strategy used by the llvm implementation of asan.
This instrumentation is done for all the memory access builtin
functions that expose a well specified memory region -- one that
explicitly states the number of bytes accessed in the region.
A special treatment is used for __builtin_strlen. The patch
instruments the access to the first byte of its argument, as well as
the access to the byte (of the argument) at the offset returned by
strlen.
For the __sync_* and __atomic* calls the patch instruments the access
to the bytes pointed to by the argument.
While doing this, I have added a new parameter to build_check_stmt to
decide whether to insert the instrumentation code before or after the
statement iterator. This allows us to do away with the
gsi_{next,prev} dance we were doing in the callers of this function.
Tested by running cc1 -fasan on variations of simple programs like:
int
foo ()
{
char foo[10] = {0};
foo[0] = 't';
foo[1] = 'e';
foo[2] = 's';
foo[3] = 't';
int l = __builtin_strlen (foo);
int n = sizeof (foo);
__builtin_memset (&foo[4], 0, n - 4);
__sync_fetch_and_add (&foo[11], 1);
return l;
}
and by starring at the gimple output which for this function is:
;; Function foo (foo, funcdef_no=0, decl_uid=1714, cgraph_uid=0)
foo ()
{
int n;
int l;
char foo[10];
int D.1725;
char * D.1724;
int D.1723;
long unsigned int D.1722;
int D.1721;
long unsigned int D.1720;
