r242524 - in /trunk: include/ChangeLog include/...


Author: mark
Date: Wed Nov 16 23:09:27 2016
New Revision: 242524

URL: https://gcc.gnu.org/viewcvs?rev=242524&root=gcc&view=rev
Log:
libiberty: Add Rust symbol demangling.

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. Mark did the code formatting to
GNU style and integration into the gcc/libiberty build system and
testsuite.
