-
+
make clean lib
-

2. How to compile an encoder executable:
make encoder
Make clean all ADDED_DEFINES+=_SYSTEM_IS_BIG_ENDIAN
To be able to use the test vectors with big endian CPU's the test programs
- need to be compiled in a different way. Note that the 16 bit input and output
- from the test programs will have the upper and lower bytes swapped with this setting.

-
* Added a new value list function 'exprValListGetNext' that can be used to
enumerate the items in a value list. Any of the items not needed (name,
value, or address) can be NULL. For example:
-
+
char *name;
EXPRTYPE val;
void *cookie;
-
+
cookie = exprValListGetNext(vlist, &name, &value, NULL, NULL);
while(cookie)
{
/* Do something with name and value */
cookie = exprValListGetNext(vlist, &name, &value, NULL, cookie);
}
-
+
You must make sure not to actually edit the returned name, because it is a
pointer into the value list to the name. This can also be used to have one
value list store globals. Global variables can be added to a value list, then
on each expression through the global list. This is useful especially if the
globals are not known at compile time, but can be adjusted by the user.
For example:
-
+
exprValList *globals;
exprValList *v1;
exprValList *v2;
char *name;
EXPRTYPE *addr;
void *cookie;
-
+
exprValListCreate(&globals);
/* Add variables to the list, perhaps read from a user file or something */
-
+
exprValListCreate(&v1);
cookie = exprValListGetNext(globals, &name, NULL, &addr, NULL);
while(cookie)
exprValListAddAddress(v1, name, addr);
cookie = exprValListGetNext(globals, &name, NULL, &addr, cookie);
}

---------------------
value. You must ensure that the stack variable exists as long as it is used
by the expression. This can permit, for example, a value name to be shared
with two different value lists like such:
-
+
EXPRTYPE global_value;
exprValListAddAddress(vlist, "global", &global_value);
exprValListAddAddress(vlist2, "global", &global_value);
-
+
Like this, the value can be directly accessed by the application, and each
value list will share it. This can also be used to replace code from this:
-
+
EXPRTYPE *a;
exprValListAdd(vlist, "var", 0.0);
exprValListGetAddress(vlist, "var", &a);
-
+
To look like this:
-
+
EXPRTYPE a;
exprValListAddAddress(vlist, "var", &a);
* Added a value list function exprValListSet to set the value of a variable
value of the item. You can still use the fast direct access method.
* Changed internal lists for function and value lists from binary trees to
linked lists.
