-/*===============================================*/
-/*========== .lines SECTION DEFINITIONS =========*/
-/*===============================================*/
-/*
- The .lines section contains a sequence of line number tables. There is no
- record structure within the section. The start of the table for a routine
- is pointed to by the block record, and the end of the table is signaled by
- an escape code.
-
- A line number table is a sequence of bytes. The default entry contains a line
- number delta (-7..+7) in the high 4 bits and a pc delta (0..15) in the low 4
- bits. Special cases, including when one or both of the values is too large
- to fit in 4 bits and other special cases are handled through escape entries.
- Escape entries are identified by the value 0x8 in the high 4 bits. The low 4
- bits are occupied by a function code. Some escape entries are followed by
- additional arguments, which may be bytes, words, or longwords. This data is
- not aligned.
-
- The initial PC offset, file number and line number are zero. Normally, the
- table begins with a dst_ln_file escape which establishes the initial file
- and line number. All PC deltas are unsigned (thus the table is ordered by
- increasing PC); line number deltas are signed. The table ends with a
- dst_ln_end escape, which is followed by a final table entry whose PC delta
- gives the code size of the last statement.
-
- Escape Semantic
- --------- ------------------------------------------------------------
- file Changes file state. The current source file remains constant
- until another file escape. Though the line number state is
- also updated by a file escape, a file escape does NOT
- constitute a line table entry.
-
- statement Alters the statement number of the next table entry. By
- default, all table entries refer to the first statement on a
- line. Statement number one is the second statement, and so on.
-
- entry Identifies the next table entry as the position of an entry
- point for the current block. The PC position should follow
- any procedure prologue code. An argument specifies the entry
- number, which is keyed to the entry number of the corresponding
- .symbols ENTRY record.
-
- exit Identifies the next table entry as the last position within
- the current block before a procedure epiloge and subsequent
- procedure exit.
-
- gap By default, the executable code corresponding to a table entry
- is assumed to extend to the beginning of the next table entry.
- If this is not the case--there is a "hole" in the table--then
- a gap escape should follow the first table entry to specify
- where the code for that entry ends.

- * Type codes for loc strings. I'm not entirely certain about all of
- * these, but they seem to work.
- * troy@cbme.unsw.EDU.AU
- * If you find a variable whose location can't be decoded, you should
- * find out it's code using "dstdump -s filename". It will record an
- * entry for the variable, and give a text representation of what
- * the locstring means. Before that explaination there will be a
- * number. In the LOCSTRING table, that number will appear before
- * the start of the location string. Location string codes are
- * five bit codes with a 3 bit argument. Check the high 5 bits of
- * the one byte code, and figure out where it goes in here.
- * Then figure out exactly what the meaning is and code it in
- * dstread.c
- *
- * Note that ranged locs mean that the variable is in different locations
- * depending on the current PC. We ignore these because (a) gcc can't handle
- * them, and (b), If you don't use high levels of optimisation they won't
- * occur.

+// OBSOLETE an escape code.
+// OBSOLETE
+// OBSOLETE A line number table is a sequence of bytes. The default entry contains a line
+// OBSOLETE number delta (-7..+7) in the high 4 bits and a pc delta (0..15) in the low 4
+// OBSOLETE bits. Special cases, including when one or both of the values is too large
+// OBSOLETE to fit in 4 bits and other special cases are handled through escape entries.
+// OBSOLETE Escape entries are identified by the value 0x8 in the high 4 bits. The low 4
+// OBSOLETE bits are occupied by a function code. Some escape entries are followed by
+// OBSOLETE additional arguments, which may be bytes, words, or longwords. This data is
+// OBSOLETE not aligned.
+// OBSOLETE
+// OBSOLETE The initial PC offset, file number and line number are zero. Normally, the
+// OBSOLETE table begins with a dst_ln_file escape which establishes the initial file
+// OBSOLETE and line number. All PC deltas are unsigned (thus the table is ordered by
+// OBSOLETE increasing PC); line number deltas are signed. The table ends with a

+// OBSOLETE gives the code size of the last statement.

+// OBSOLETE until another file escape. Though the line number state is
+// OBSOLETE also updated by a file escape, a file escape does NOT
+// OBSOLETE constitute a line table entry.
+// OBSOLETE
+// OBSOLETE statement Alters the statement number of the next table entry. By
+// OBSOLETE default, all table entries refer to the first statement on a
+// OBSOLETE line. Statement number one is the second statement, and so on.
+// OBSOLETE
+// OBSOLETE entry Identifies the next table entry as the position of an entry

+// OBSOLETE number, which is keyed to the entry number of the corresponding
+// OBSOLETE .symbols ENTRY record.
+// OBSOLETE
+// OBSOLETE exit Identifies the next table entry as the last position within
+// OBSOLETE the current block before a procedure epiloge and subsequent
+// OBSOLETE procedure exit.
+// OBSOLETE
+// OBSOLETE gap By default, the executable code corresponding to a table entry
+// OBSOLETE is assumed to extend to the beginning of the next table entry.
+// OBSOLETE If this is not the case--there is a "hole" in the table--then
