CXXFILT options

You can use the following options with CXXFILT.

SYMMAP | NOSYMMAP

Default: NOSYMMAP

Produces a symbol map on standard output. This map contains a list of the mangled names and their corresponding demangled names. The map only displays the first 40 bytes of each demangled name; it truncates the rest. Mangled names are not truncated.

If an input mangled name does not have a demangled version, the symbol mapping does not display it.

The symbol mapping is displayed after the end of the input stream is encountered, and after CXXFILT terminates.

SIDEBYSIDE | NOSIDEBYSIDE

Default: NOSIDEBYSIDE

Each mangled name that is encountered in the input stream is displayed beside its corresponding demangled name. If you do not specify this option, then only the demangled names are printed. In either case, trailing characters in the input name that are not part of a mangled name appear next to the demangled name. For example, if an extraneous xxxx is input with the mangled name pr__3FOOF, then the SIDEBYSIDE option would produce this result:

FOO::pr()        pr__3FOOFvxxxx

WIDTH(width) | NOWIDTH

Default: NOWIDTH

Prints demangled names in fields, width characters wide. If the name is shorter than width, it is padded on the right with blanks; if longer, it is truncated to width. The value of width must be greater than 0. If width is greater than the record width, then the output is wrapped.

REGULARNAME | NOREGULARNAME

Default: REGULARNAME

This option demangles regular names such as pr__3FOOFv to FOO:pr().

The mangled name that is supplied to CXXFILT is treated as a regular name by default. Specifying the NOREGULARNAME option will turn the default off. For example, specifying the CLASSNAME option without the NOREGULARNAME option will cause CXXFILT to treat the mangled name as either a regular name or stand-alone class name.

CLASSNAME | NOCLASSNAME

Default: NOCLASSNAME

This option demangles stand-alone class names such as Q2_1X1Y to X::Y.

To request that the mangled names be treated as stand-alone class names only, and never as a regular name, use both CLASSNAME and NOREGULARNAME.

SPECIALNAME | NOSPECIALNAME

Default: NOSPECIALNAME

This option demangles special names, such as compiler-generated symbol names; for example, __vft1X is demangled to X::virtual-fn-table-ptr.

To request that the mangled names be treated as special names only, and never as regular names, use CXXFILT (SPECIALNAME NOREGULARNAME.

Unknown type of name

If you cannot specify the type of name, use CXXFILT (SPECIALNAME CLASSNAME. This causes CXXFILT to attempt to demangle the name in the following order:

Regular name
Stand-alone class name
Special name
