2017-03-27cplus_demangle_fill_component: Handle DEMANGLE_COMPONENT_RVALUE_REFERENCEpalves
This patch almost a decade ago: ... 2007-08-31 Douglas Gregor <doug.gregor@gmail.com> * cp-demangle.c (d_dump): Handle DEMANGLE_COMPONENT_RVALUE_REFERENCE. (d_make_comp): Ditto. ... ... missed doing the same change to cplus_demangle_fill_component that was done to d_make_comp. I.e., teach it to only validate that we're not passing in a "right" subtree. GDB has recently (finally) learned about rvalue references, and a change to make it use cplus_demangle_fill_component more ran into an assertion because of this. (GDB is the only user of cplus_demangle_fill_component in both the gcc and binutils-gdb trees.) libiberty/ChangeLog: 2017-03-27 Pedro Alves <palves@redhat.com> * cp-demint.c (cplus_demangle_fill_component): Handle DEMANGLE_COMPONENT_RVALUE_REFERENCE. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@246502 138bc75d-0d04-0410-961f-82ee72b054a4
2017-03-13libiberty: Initialize d_printing in all cplus_demangle_fill_* functions.mark
While integrating the d_printing recursion guard change into gdb I noticed we forgot to initialize the demangle_component d_printing field in cplus_demangle_fill_{name,extended_operator,ctor,dtor}. As is done in cplus_demangle_fill_{component,builtin_type,operator}. It happened to work because in gcc all demangle_components were allocated through d_make_empty. But gdb has its own allocation mechanism (as might other users). libiberty/ChangeLog: * cp-demangle.c (cplus_demangle_fill_name): Initialize demangle_component d_printing.

Adds Rust symbol demangler. Rust mangles symbols using GNU_V3 style, adding a hash and various special character subtitutions. This adds a new rust style to cplus_demangle and adds 3 helper functions rust_demangle, rust_demangle_sym and rust_is_mangled. rust-demangle.c was written by David.

2016-11-15libiberty: demangler crash with missing :? or fold expression component.mark
When constructing an :? or fold expression that requires a third expression only the first and second were explicitly checked to not be NULL. Since the third expression is also required in these constructs it needs to be explicitly checked and rejected when missing. Otherwise the demangler will crash once it tries to d_print the NULL component. Added two examples to demangle-expected of strings that would crash before this fix. Found by American Fuzzy Lop (afl) fuzzer. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@242451 138bc75d-0d04-0410-961f-82ee72b054a4
2016-11-15libiberty: Fix some demangler crashes caused by reading past end of input.mark
In various situations the cplus_demangle () function could read past the end of input causing crashes. Add checks in various places to not advance the demangle string location and fail early when end of string is reached. Add various examples of input strings to the testsuite that would crash test-demangle before the fixes. Found by using the American Fuzzy Lop (afl) fuzzer. libiberty/ChangeLog: * cplus-dem.c (demangle_signature): After 'H', template function, no success and don't advance position if end of string reached. (demangle_template): After 'z', template name, return zero on premature end of string. (gnu_special): Guard strchr against searching for zero characters.
