Setting TMode bit for PseudoDisassembler

[bdemick]

I'm attempting to use the PseudoDisassembler to do some rapid instruction decoding, but can't seem to figure out how to properly set the PseudoDisassemblerContext to set the TMode bit for every invocation of the disassembler. I'm doing this in Python, but followed the DoThumbDisassemble.java example script.

disasm = PseudoDisassembler(currentProgram)    
ctx = PseudoDisassemblerContext(currentProgram.getProgramContext())    
tmodeReg = ctx.getRegister("TMode")    
thumbMode = RegisterValue(tmodeReg, BigInteger.ONE)    
ctx.setFutureRegisterValue(toAddr(0), currentProgram.maxAddress, thumbMode)    

# Then when disassembling...
pi = disasm.disassemble(addr, ctx, False)

However, this doesn't seem to have the desired effect, as it's definitely not disassembling in Thumb mode.

I didn't quite see an exact translation from the DoThumbDisassemble.java script, which uses the regular disassembly engine and not the PseudoDisassembler, so I'm fumbling around with the different API calls and not finding one that seems to allow me to globally set the TMode bit.

Any pointers on the right combination here?

This seems to have done the trick:

tmodeReg = currentProgram.getProgramContext().getRegister("TMode")
thumbMode = RegisterValue(tmodeReg, BigInteger.ONE)
currentProgram.getProgramContext().setDefaultDisassemblyContext(thumbMode)
disasm = PseudoDisassembler(currentProgram)
