F-Lines can also be used to convert long calls or jumps to relative jumps or calls
which reduces the app's relocation table and hence the app’s size. See section
7.1 File Format
for a description of the relocation table.
8.6. Optimizing Code Space
One of the optimizations involves reducing the apps relocation table. All
references to an app’s global variables made by an app require a relocation entry
to be stored with the app. If there are multiple references to a particular global
variable in an app, the global references can be replaced with local pointers as
shown in the example below.
static WINDOW appW;
static WIN_RECT appWRect;
void AP_EventHandler(pFrame self, PEvent e) {
WINDOW *winPtr = &appW;
switch (e->command) {
case CM_START:
appWRect = *(e->info.startInfo.startRect);
if (WinOpen( winPtr, &appWRect, WF_TTY | WF_DUP_SCR))
WinClr( winPtr );
else
EV_quit();
break;
case CM_ACTIVATE:
EV_defaultHandler(e);
WinBeginPaint( winPtr );
WinActivate( winPtr );
WinStr( winPtr, "Just activated\n" );
break;
.
.
.
}
}
In the preceding example, since there were several references to the global
variable
appW
the pointer winPtr was initialized to the address of
appW
at the
entry point to the
AP_EventHandler
routine and used instead of &appW. Since
there was only one additional reference to
appWRect
an additional pointer to
access that global was not created.
