<p>6.4.1 Structure of Call Frame Information</p>
|
|||
|
|
<p>DWARF supports virtual unwinding by defining an architecture independent
|
|||
|
|
basis for recording how procedures save and restore registers during their
|
|||
|
|
lifetimes. This basis must be augmented on some machines with specific
|
|||
|
|
information that is defined by an architecture specific ABI authoring
|
|||
|
|
committee, a hardware vendor, or a compiler producer. The body defining a
|
|||
|
|
specific augmentation is referred to below as the “augmenter.”</p>
|
|||
|
|
<p>Abstractly, this mechanism describes a very large table that has the
|
|||
|
|
following structure:</p>
|
|||
|
|
<table>
|
|||
|
|
<tr>
|
|||
|
|
<th>LOC</th><th>CFA</th><th>R0</th><th>R1</th><td>...</td><th>RN</th>
|
|||
|
|
</tr>
|
|||
|
|
<tr>
|
|||
|
|
<th>L0</th> <td></td> <td></td> <td></td> <td></td> <td></td>
|
|||
|
|
</tr>
|
|||
|
|
<tr>
|
|||
|
|
<th>L1</th> <td></td> <td></td> <td></td> <td></td> <td></td>
|
|||
|
|
</tr>
|
|||
|
|
<tr>
|
|||
|
|
<td>...</td><td></td> <td></td> <td></td> <td></td> <td></td>
|
|||
|
|
</tr>
|
|||
|
|
<tr>
|
|||
|
|
<th>LN</th> <td></td> <td></td> <td></td> <td></td> <td></td>
|
|||
|
|
</tr>
|
|||
|
|
</table>
|
|||
|
|
<p>The first column indicates an address for every location that contains code
|
|||
|
|
in a program. (In shared objects, this is an object-relative offset.) The
|
|||
|
|
remaining columns contain virtual unwinding rules that are associated with
|
|||
|
|
the indicated location.</p>
|
|||
|
|
<p>The CFA column defines the rule which computes the Canonical Frame Address
|
|||
|
|
value; it may be either a register and a signed offset that are added
|
|||
|
|
together, or a DWARF expression that is evaluated.</p>
|
|||
|
|
<p>The remaining columns are labeled by register number. This includes some
|
|||
|
|
registers that have special designation on some architectures such as the PC
|
|||
|
|
and the stack pointer register. (The actual mapping of registers for a
|
|||
|
|
particular architecture is defined by the augmenter.) The register columns
|
|||
|
|
contain rules that describe whether a given register has been saved and the
|
|||
|
|
rule to find the value for the register in the previous frame.</p>
|
|||
|
|
<p>…</p>
|
|||
|
|
<p>This table would be extremely large if actually constructed as
|
|||
|
|
described. Most of the entries at any point in the table are identical to
|
|||
|
|
the ones above them. The whole table can be represented quite compactly by
|
|||
|
|
recording just the differences starting at the beginning address of each
|
|||
|
|
subroutine in the program.</p>
