Primary goal: good coverage of the backend code generators. The
|
||
|
|
following list was derived from the token list in SDCC.lex
|
||
|
|
|
||
|
|
Follows is a list of tokens and the test case that covers them. If no
|
||
|
|
case is listed then the token is not yet covered. Special cases are
|
||
|
|
listed under the token. If the token is listed as covered then the
|
||
|
|
special cases are also covered.
|
||
|
|
|
||
|
|
The cases generally assume that on stack local variables and
|
||
|
|
parameters are accessed using the same methods and hence doesn't test
|
||
|
|
stack based parameters.
