The P constraint letter is supposed to match every constant which is

able to handle const_wide_int yet.  It works with predicates so the

Fix location of sizeof/alignof (PR c++/80016)

PR c++/80016 reports an issue with bizarre underlined range
for a complicated expression.

The root cause for the incorrect *starting* location of that range
is that alignof and sizeof expressions currently have
start == finish == caret at the opening parenthesis of the
expression.

locations for alignof and sizeof expressions.

libiberty: Limit demangler maximum d_print_comp recursion call depth.

The fix for PR demangler/70909 and 67264 (endless demangler recursion)
catches when a demangle_component is printed in a cycle. But that doesn't
protect the call stack blowing up from non-cyclic nested types printed
recursively through d_print_comp. This can happen by a (very) long mangled
string that simply creates a very deep pointer or qualifier chain. Limit
the recursive d_print_comp call depth for a d_print_info to 1K nested
types.

libiberty/ChangeLog:

        * cp-demangle.c (MAX_RECURSION_COUNT): New constant.
        (struct d_print_info): Add recursion field.
        (d_print_init): Initialize recursion.
        (d_print_comp): Check and update d_print_info recursion depth.

libiberty: Always return NULL if d_add_substitution fails.

d_add_substitution can fail for various reasons, like when the subs array
is full. If d_add_substitution fails d_substitution should return NULL
early and not try to continue. Every other call of d_add_substitution
is handled in the same way.

libiberty/ChangeLog:

* cp-demangle.c (d_substitution): Return NULL if d_add_substitution
fails.

From-SVN: r247055

libiberty: Don't update and remove did_subs field from demangler structs.

The d_info field did_subs was used for estimating the string output
size. It was no longer used when the malloc-less callback interface
was introduced in 2007 (svn r121305). But the field was still updated.
When backtracking was introduced in 2013 (svn r205292) did_subs was
also added to the d_info_checkpoint struct. But except for updating
the field it was still not used.

Since it is never used just stop updating the field and remove it
from the two structs.

libiberty/ChangeLog:

* cp-demangle.h (struct d_info): Remove did_subs field.
* cp-demangle.c (struct d_info_checkpoint): Likewise.
