I have no idea what you mean by "segments in a compiler". Could you
elaborate?

Are you asking different phases of compilation?

I think you are ocnfusing your terms. A compiler is a program that compiles
a program into object code which is then linked into an executable by a
linker, sometimes by the compiler itself.

Just what is your question?

Segments are a platform-specific linkage concept, not a C++ concept.

Consult the reference documentation for your tools.

I think you are ocnfusing your terms. A compiler is a program that compiles
a program into object code which is then linked into an executable by a
linker, sometimes by the compiler itself.

That object code is typically organized into sections or segments.
Code goes into a code or "text" section, static read/write data into a
data section, data which can be initialized to zero bits into yet
another section and so on. A C++ compiler may use special sections due
to its linkage model for inline functions and other data which may be
generated more than once in different compilation units and have to be
merged. Special sections may be used for pointers to the constructor
and destructor stubs, so that when these are collected together into a
section, they form a table that can be iterated over to do the call-
outs. All of this is very platform-specific, of course.

Segments, in linking terminology, are a concept for organizing a
translation unit's code and data. This is not required by the C++
language, but added on by many compilers and linkers. There is no
official standard either.

Some common segments:
text -- could contain read only data.
code -- the executable code
read/write -- run-time variables
