<p>
This defines the register <tt>AL</tt> and assigns it values (with
<tt>DwarfRegNum</tt>) that are used by <tt>gcc</tt>, <tt>gdb</tt>, or a debug
-information writer (such as <tt>DwarfWriter</tt>
-in <tt>llvm/lib/CodeGen/AsmPrinter</tt>) to identify a register. For register
+information writer to identify a register. For register
<tt>AL</tt>, <tt>DwarfRegNum</tt> takes an array of 3 values representing 3
different modes: the first element is for X86-64, the second for exception
handling (EH) on X86-32, and the third is generic. -1 is a special Dwarf number
<li><tt>getCalleeSavedRegs</tt> — Returns a list of callee-saved registers
in the order of the desired callee-save stack frame offset.</li>
-<li><tt>getCalleeSavedRegClasses</tt> — Returns a list of preferred
- register classes with which to spill each callee saved register.</li>
-
<li><tt>getReservedRegs</tt> — Returns a bitset indexed by physical
register numbers, indicating if a particular register is unavailable.</li>
</p>
<ul>
-<li><tt>isMoveInstr</tt> — Return true if the instruction is a register to
- register move; false, otherwise.</li>
-
<li><tt>isLoadFromStackSlot</tt> — If the specified machine instruction is
a direct load from a stack slot, return the register number of the
destination and the <tt>FrameIndex</tt> of the stack slot.</li>
a direct store to a stack slot, return the register number of the
destination and the <tt>FrameIndex</tt> of the stack slot.</li>
