Bug ID: 67267
Summary: demangler does not handle "sr" correctly
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ian at airs dot com
CC: gbenson at redhat dot com
Target Milestone: ---
I don't have the source for this, but g++ generated this symbol name:
_ZN9__gnu_cxx17__normal_iteratorIPK1EIN1F1G1HEESt6vectorIS5_SaIS5_EEEC2IPS5_EERKNS0_IT_NS_11__enable_ifIXsr3std10__are_sameISE_SD_EE7__valueESA_E1IEEE
The demangler failed to demangle it. However, this is a valid mangled name.
The demangler does not handle the sr correctly. It treats sr as a type
followed by a name. However, the description of sr is this:
<unresolved-name> ::= [gs] <base-unresolved-name>
::= sr <unresolved-type> <base-unresolved-name>
::= srN <unresolved-type> <unresolved-qualifier-level>+ E
<base-unresolved-name>
::= [gs] sr <unresolved-qualifier-level>+ E
<base-unresolved-name>
<unresolved-type> ::= <template-param>
::= <decltype>
::= <substitution>
<unresolved-qualifier-level> ::= <simple-id>
<simple-id> ::= <source-name> [ <template-args> ]
<base-unresolved-name> ::= <simple-id>
::= on <operator-name>
::= on <operator-name> <template-args>
::= dn <destructor-name>
In this mangled name the string following "sr" does not match
<unresolved-type>, so this is the <unresolved-qualifier-level>+ E case. The
demangler does not handle that case.
The correct demangling is something like
__gnu_cxx::__normal_iterator<E<F::G::H> const*, std::vector<E<F::G::H>,
std::allocator<E<F::G::H> > >
>::__normal_iterator<E<F::G::H>*>(__gnu_cxx::__normal_iterator<E<F::G::H>*,
__gnu_cxx::__enable_if<std::__are_same<E<F::G::H>*, E<F::G::H>*>::__value,
std::vector<E<F::G::H>, std::allocator<E<F::G::H> > > >::I> const&)
