...hat const_cast? Also, the patch does not restore the TargetSubtargetInfo to its original state. So if you changed from Thumb to ARM mode, but not back to Thumb, the code emitter will generate broken machine code. Unfortunately, the TargetSubtargetInfo class does not expose a copy constructor or a setFeatureBits() method. Should it? Or should we expect the inline assembly to be responsible for restoring the mode itself?

I can only reproduce the issue when that code is inline assembly in a bitcode file. Attached is a bitcode file and Makefile to demonstrate. Calling 'make' will dump two object files 'c.o' and 'asm.o'. The former is created
