+## BACKGROUND
+
+As a result of adopting [230524.1][230524.1], "Location
+Descriptions on the Stack," and other recent proposals in V6,
+we have some new class and form names in the DWARF spec:
+
+Classes:
+
+- exprval
+- exprloc
+- locexpr
+- loclist
+
+Form:
+
+- `DW_FORM_expression`
+
+Classes exprval and locexpr use `DW_FORM_expression` (which is
+a renaming of `DW_FORM_exprloc` from V5).
+
+Classes loclist and vallist use `DW_FORM_loclistx` (this last
+carried over from V5).
+
+Notice that the exprval and exprloc names indicate the
+representation first (expression) and the meaning second
+(val vs loc) while locexpr and loclist are the opposite.
+
+Further, `DW_FORM_expression` is rather long compared to the
+usual abbreviated spelling of other classes and forms.
+
+
+## PROPOSAL
+
+1) For the class names, adopt the order meaning then
+representation. That means change exprval to valexpr and
+exprloc to locexpr. The resulting set of names is: locexpr,
+loclist, valexpr and vallist.
+
+2) Rename `DW_FORM_expression` to `DW_FORM_expr`. The latter
+is more consistent with the abbreviation conventions in the
+classes that use it (locexpr, valexpr).
+
+3) Rename `DW_FORM_loclistx` to `DW_FORM_listx`. This better
+reflects the fact that that form is used with both value
+lists and location lists and not just locations.
+
+These are simple renamings only. `DW_FORM_expr` will use code
+0x18 (used by `DW_FORM_exprloc` in V5), and the two names can
+be treated as synonyms. Similarly `DW_FORM_listx` can use code
+0x22 (used by `DW_FORM_loclistx` in V5), and those two names
+can be treated as synonyms.
+
+Note that `DW_FORM_expression` is new in V6 and already
+defined as a renaming of `DW_FORM_exprloc`.
+
+Note that `DW_FORM_rnglistx` (carried over from V5) already
+follows the meaning then representation order and needs no
+change.
