2017-04-21libiberty: Limit demangler maximum d_print_comp recursion call depth.Mark Wielaard2-3/+19
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. From-SVN: r247056
2017-04-21libiberty: Always return NULL if d_add_substitution fails.Mark Wielaard2-1/+7
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
2017-04-21libiberty: Don't update and remove did_subs field from demangler structs.Mark Wielaard3-12/+10
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. (d_template_param): Don't update did_subs. (d_substitution): Likewise. (d_checkpoint): Don't assign did_subs. (d_backtrack): Likewise. (cplus_demangle_init_info): Don't initialize did_subs.
