2120 This causes the section <parameter>name</parameter> to load with its end
2121 address just below <parameter>addr</parameter>. Subsequent sections are
2122 loaded at progressively lower addresses. This may lead to inefficient file
2123 encoding for some targets. As of this writing, it will also almost
2124 certainly do the wrong thing for a raw target.

2128 This is useful for aligning a block of code with high memory. As an
2129 example, if the total size of a section is $100 bytes and a high address of
2130 $FE00 is specified, the section will actually load at $FD00.
