Smali error with FRF83 #36

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What seems to be the problem? Getting issues rebuilding classes.dex file with 
smali v1.2.3.. Classes.dex is deodoxed from FRF83 Froyo 2.2. services.jar.

What is the exact smali/baksmali command that you ran?
java -Xmx512M -jar smali.jar classout/ -o new-classes.dex

What version are you using? v.1.2.3.

Please provide any additional information below: error messages, symptoms,
etc.

Did you modify the file at all?

Also, can you pastebin the snippet of smali code that it is complaining about?

Yes, file was modified here on statisbaricon.smalli to modify date text color 
to cyan:

    .line 60
    const/high16 v6, -0xff0001

I ran it without editing it and smali worked fine, but once edited to change 
color it errors. 

Attached if both the classout folder zipped. Unzip so you can run smali 
yourself and see it if gives you the error also. And attached is the 
statisbaricon.smali file where the code was changed.

This is the expected behavior. That instruction takes the specified short value 
(16 bits) and then shifts it left by 16 bits and loads it into the specified 
register. But the literal value you are trying to use can't fit into 16 bits, 
and so it (correctly) errors out.

The literal value for that instruction is limited to 16 bits, because anything 
more than 16 bits would get shifted off when the left shift is performed. This 
instruction can obviously only be used when the literal value you want only 
contains zeros in the low-order 16 bits. But for the cyan color, the low order 
16 bits are actually all 1s. So you can't use the const/high16 instruction.

Also: Why do you insist on using a negative value? Color codes are much easier 
to specify as a positive value. See my comments about this here:

If you want a cyan color (i.e. #00FFFF RGB), you should use

const v6, 0xff00ffff
