+/* Virtual memory address of the text section.

+   * OMAGIC and NMAGIC files:
+       (object files: text for "relocatable addr 0" right after the header)
+       start at 0, offset is EXEC_BYTES_SIZE, size as stated.
+   * The text address, offset, and size of ZMAGIC files depend
+     on the entry point of the file:
+     * entry point below TEXT_START_ADDR:
+       (hack for SunOS shared libraries)
+       start at 0, offset is 0, size as stated.
+     * If N_HEADER_IN_TEXT(x) is true (which defaults to being the
+       case when the entry point is EXEC_BYTES_SIZE or further into a page):
+       no padding is needed; text can start after exec header.  Sun
+       considers the text segment of such files to include the exec header;
+       for BFD's purposes, we don't, which makes more work for us.
+       start at TEXT_START_ADDR + EXEC_BYTES_SIZE, offset is EXEC_BYTES_SIZE,
+       size as stated minus EXEC_BYTES_SIZE.

+       aligned)): (padding is needed so that text can start at a page boundary)
+       start at TEXT_START_ADDR, offset TARGET_PAGE_SIZE, size as stated.
+
+    Specific configurations may want to hardwire N_HEADER_IN_TEXT,
+    for efficiency or to allow people to play games with the entry point.
+    In that case, you would #define N_HEADER_IN_TEXT(x) as 1 for sunos,
+    and as 0 for most other hosts (Sony News, Vax Ultrix, etc).

+    (The default is a heuristic that will break if people try changing
+    the entry point, perhaps with the ld -e flag.)
+
+    * QMAGIC is always like a ZMAGIC for which N_HEADER_IN_TEXT is true,

+/* RESTRICTIONS:
+
+   pstack currently works only on Linux, only on an x86 machine running
+   32 bit ELF binaries (64 bit not supported).  Also, for symbolic
+   information, you need to use a GNU compiler to generate your
+   program, and you can't strip symbols from the binaries.  For thread
+   information to be dumped, you have to use the debug-aware version
+   of libpthread.so.  (To check, run 'nm' on your libpthread.so, and
+   make sure that the symbol "__pthread_threads_debug" is defined.)
+
+   The details of pulling stuff out of ELF files and running through
+   program images is very platform specific, and I don't want to
+   try to support modes or machine types I can't test in or on.
+   If someone wants to generalize this to other architectures, I would
+   be happy to help and coordinate the activity.  Please send me whatever
+   changes you make to support these machines, so that I can own the
+   central font of all truth (at least as regards this program).
+
+   Thanks
