[Bug 250388] unable to make buildworld releng/12.1. clang always crashes

[Bug 250702] c++filt crashes on a particular symbol
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=250702
--- Comment #7 from Dimitry Andric ---
It's pretty interesting, when I use this simple little demangle.cpp program:
#include
#include
#include
static char *demangle_buf;
static size_t demangle_size = 2 * 1024;
static void demangle(const char *mangled_name)
{
int status;
char *demangled_name = abi::__cxa_demangle(mangled_name, demangle_buf,
_size, );
switch (status) {
case 0:
printf("%s -> %s\n", mangled_name, demangled_name);
break;
case -1:
printf("error: memory allocation failure while demangling %s\n",
mangled_name);
break;
case -2:
printf("error: %s is not a valid C++ mangled name\n", mangled_name);
break;
case -3:
printf("error: invalid argument(s) while demangling %s\n", mangled_name);
break;
default:
printf("error: unknown status %d while demangling %s\n", status,
mangled_name);
break;
}
}
int main(int argc, char *argv[])
{
if (argc <= 1) {
printf("Usage: %s mangled_name ...\n", argv[0]);
return 1;
}
if ((demangle_buf = (char *)malloc(demangle_size)) == NULL) {
printf("Unable to allocate memory for demangle buffer\n");
return 1;
}
for (int i = 1; i < argc; ++i) {
demangle(argv[i]);
}
free(demangle_buf);
return 0;
}
it works just fine on the identifier:
% ./demangle '_ZZ5func1vENK3$_0clEv'
_ZZ5func1vENK3$_0clEv -> func1(void)::$_0::operator()(void) const
However, it uses the *older* copy of elftoolchain's libelftc_dem_gnu3.c in
contrib/libcxxrt!
E.g. something has been broken in this area in more recent releases of
elftoolchain...

[Bug 250702] c++filt crashes on a particular symbol
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=250702
--- Comment #8 from Dimitry Andric ---
The simple case, e.g. '_ZZ5func1vENK3$_0clEv' has regressed with
https://sourceforge.net/p/elftoolchain/code/3531/ ("libelftc: revamped
demangler support for function return type"), aka
https://github.com/elftoolchain/elftoolchain/commit/68c2224b7 .
The https://sourceforge.net/p/elftoolchain/tickets/539/ has another example
however,
'_ZZN9libunwind17LocalAddressSpace18findUnwindSectionsEjRNS_18UnwindInfoSectionsEENUlP12dl_phdr_infojPvE_8__invokeES4_jS5_',
which GNU c++filt unpacks to
'libunwind::LocalAddressSpace::findUnwindSections(unsigned int,
libunwind::UnwindInfoSections&)::{lambda(dl_phdr_info*, unsigned int,
void*)#1}::__invoke(dl_phdr_info*, unsigned int, void*)'.
With the elftc demangler, before upstream r3531, it simply returns "not a valid
mangled name", while after upstream r3531, it asserts "(ddata->output.size >
0)".
What seems to happen is that r3531 added a cpp_demangle_data::cur_output
member, and this is being used for any cpp_demangle_push_str() call. When
cpp_demangle_read_sname() reads the '5func1' part of the original string, it
calls cpp_demangle_push_str to push the 'func1' name that it decodes, but at
that point cur_output is *not* pointing to ddata->output, which the assert
expects.

So far I've only been fixing assertions, which there are quite a few of. But unfortunately libelftc's demangler does not seem to implement any of the machinery to handle C++11 features, like unnamed types, lambda's etc. Adding these does not look trivial. -- You are receiving this mail because: You are the assignee for the bug. ___ freebsd-toolchain@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "freebsd-toolchain-unsubscr...@freebsd.org"
