PR c++/54875 - Error with alias template that resolves to an enum
Consider this short example:
1 template<typename T>
2 using AddConst = T const;
3
4 enum FwdEnum : int;
5
6 int main() {
7 AddConst<FwdEnum> *ptr = nullptr;
8 }
At line 7, when we build the type for AddConst<FwdEnum> in
lookup_template_class_1, the resulting type is the enum FwdEnum. This
confuses lookup_template_class_1 near the if below, wrongly making it
taking the branch and thus calling tsubst_enum while it shouldn't:
if (TREE_CODE (t) == ENUMERAL_TYPE && !is_dependent_type)
/* Now that the type has been registered on the instantiations
list, we set up the enumerators. Because the enumeration
constants may involve the enumeration type itself, we make
sure to register the type first, and then create the
constants. That way, doing tsubst_expr for the enumeration
constants won't result in recursive calls here; we'll find
the instantiation and exit above. */
tsubst_enum (template_type, t, arglist);
Before the alias template feature, the only reason why TREE_CODE (t)
== ENUMERAL_TYPE would be true is when lookup_template_class_1 is
called for an enum that is a member of a class template. But that
condition can be also true for an alias template instantiation.
So I guess that condition should be changed to TREE_CODE
(template_type) == ENUMERAL_TYPE, to specifically detect the member
enum of a class template case. Note that for the alias template
instantiation case above, template_type points to a TEMPLATE_TYPE_PARM
which name is AddConst.
This is what the patchlet below does.
Bootstrapped and tested on x86_64-unknown-linux-gnu against trunk.

PR c++/54466 - ICE with alias template which type-id is const qualified
Consider this short example:
template<typename T>
struct X { };
template<typename T>
using Y = const X<T>;
using Z = Y<int>;
G++ crashes in lookup_class_template_1 while trying to build the alias
template instantiation Y<int>.
I think this is indirectly due to the fact that that
lookup_class_template_1 can now yield a const qualified type like
'const X<T>'.
As a consequence, the code in lookup_template_class_1 that was trying
to access the TYPE_STUB_DECL field of the result of
lookup_template_class_1 should now be adjusted to access the
TYPE_STUB_DECL of the main variant of the resulting type instead (and
that is TYPE_MAIN_DECL); because qualified types (constructed with
build_qualified_type) have their TYPE_STUB_DECL set to NULL.
Fixed thus and tested on x86_64-unknown-linux-gnu against trunk.

Instrument built-in memory access function calls
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;
