C++ Mangled Symbol Names

iniTerm lists corresponding to these procedures, and places pointers (ctors and

dtors addresses) to them in the tandeminfo segment of the object file.

___INIT__ and __TERM__

Apart from the procedures from runtime-library, the user program itself might

contain procedures with these names (for example, __INIT__< name>). These

functions need not be called by the program explicitly; they are executed in

alphabetical order of the procedure names in case of __INIT__ procedures and

reverse alphabetic order in case of __TERM__ functions. The linker builds two

iniTerm lists corresponding to these procedures and places pointers (initz and

termz addresses) to them in the tandeminfo segment of the object file.

C++ Mangled Symbol Names

In order to identify to the linker a C++ function (other than one declared with extern

“c”), you must use the symbol’s mangled name. The linker does not make the

correspondence between unmangled and mangled names. For example, if

<symbolname> or <entrypoint> in the two previous subsections are in a C++

program, these values must be the mangled version of their source-code names.

How to Set Run-Time Attributes of Your Loadfile

At link time, the linker sets certain run-time attributes of the loadfile it is building to

default values, unless you override a default by inserting the -set attribute

<value> option.

See also Default Setting and Checking of File Attributes on page 2-19.

Each -set attribute option can affect only one attribute, so this option must be

re-inserted for each attribute that is changed. Permitted attributes are shown in the

following list, which summarizes the values that can be set. The linker places these

attribute values in the loadfile being linked in order to make them available to the

system at load time.

cppdialect

sets the C++ dialect of the output loadfile. The values are cppneutral or v2 or

v3.
