.SH NAME
|
|
llvm-cxxfilt \- LLVM symbol name demangler
|
|
.SH SYNOPSIS
|
|
.sp
|
|
\fBllvm\-cxxfilt\fP [\fIoptions\fP] [\fImangled names...\fP]
|
|
.SH DESCRIPTION
|
|
.sp
|
|
\fBllvm\-cxxfilt\fP is a symbol demangler that can be used as a replacement
|
|
for the GNU \fBc++filt\fP tool. It takes a series of symbol names and
|
|
prints their demangled form on the standard output stream. If a name cannot be
|
|
demangled, it is simply printed as is.
|
|
.sp
|
|
If no names are specified on the command\-line, names are read interactively from
|
|
the standard input stream. When reading names from standard input, each input
|
|
line is split on characters that are not part of valid Itanium name manglings,
|
|
i.e. characters that are not alphanumeric, \(aq.\(aq, \(aq$\(aq, or \(aq_\(aq. Separators between
|
|
names are copied to the output as is.
