* Special ".note" entry specifying the ABI version. See
* http://www.netbsd.org/Documentation/kernel/elf-notes.html
* for more information.
- *
- * For all arches except sparc, gcc emits the section directive for the
- * following struct with a PROGBITS type. However, newer versions of binutils
- * (after 2.16.90) require the section to be of NOTE type, to guarantee that the
- * .note.ABI-tag section correctly ends up in the first page of the final
- * executable.
- *
- * Unfortunately, there is no clean way to tell gcc to use another section type,
- * so this C file (or the C file that includes it) must be compiled in multiple
- * steps:
- *
- * - Compile the .c file to a .s file.
- * - Edit the .s file to change the 'progbits' type to 'note', for the section
- * directive that defines the .note.ABI-tag section.
- * - Compile the .s file to an object file.
- *
- * These steps are done in the invididual Makefiles for each applicable arch.
