In the Gecko code we have a bunch of preprocessor conditions that help us conditionally compile code for specific platforms. These can get confusing so here is a handy-dandy table to help you keep them straight.

OS Windows OS X Linux-gtk Android iOS
Product Desktop B2G Desktop B2G Desktop B2G Mulet Fennec B2G B2GDROID iOS
XP_WIN ✓ ✓                  
XP_DARWIN     ✓ ✓             ✓
XP_MACOSX     ✓ ✓              
XP_IOS                     ✓
XP_UNIX     ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓
XP_LINUX         ✓ ✓ ✓ ✓ ✓ ✓  
ANDROID               ✓ ✓ ✓  
MOZ_B2G   ✓   ✓   ✓ ✓   ✓ ✓  
MOZ_B2GDROID                   ✓  
MOZ_MULET             ✓        
MOZ_WIDGET_GTK         ✓ ✓ ✓        
MOZ_WIDGET_ANDROID               ✓   ✓  
MOZ_WIDGET_GONK                 ✓    
MOZ_WIDGET_UIKIT                     ✓

Prefs files

Here is a similar table, but to see which prefs get used in which product:

OS Windows OS X Linux-gtk Android iOS
Product Desktop B2G Desktop B2G Desktop B2G Mulet Fennec B2G iOS
all.js ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓ ✓
firefox.js ✓   ✓   ✓   ✓      
mobile.js               ✓    
b2g.js   ✓   ✓   ✓ ✓   ✓  
mulet.js             ✓      

WARNING: Until bug 1174234 is resolved firefox.js prefs will override mulet.js prefs on Mulet.

Reftest conditions

Here is another table that tells you what conditions are true on various platforms for use in reftest.list conditions.

OS Windows OS X Linux-gtk Android iOS
Product Desktop B2G Desktop B2G Desktop B2G Mulet Fennec B2G iOS
B2G                 ✓  
B2GDT   ✓   ✓   ✓        
Android               ✓    
cocoaWidget     ✓ ✓            
gtkWidget         ✓ ✓ ✓      
qtWidget                    
winWidget ✓ ✓                
Mulet             ✓      

Mochitest conditions

Here is another table that tells you what different condition values are on various platforms for use in mochitest.ini/a11y.ini/chrome.ini/browser.ini conditions.

OS Windows OS X Linux-gtk Android iOS
Product Desktop B2G Desktop B2G Desktop B2G Mulet Fennec B2G iOS
os win ?? mac ?? linux ?? ?? android b2g ??
toolkit windows ?? cocoa ?? gtk2 or gtk3 ?? ?? android gonk ??
