...did you change the default value for JumpTableDataSection? Jump
tables really should not go into .data. That is a security hole.
They should be read-only.
When you create global symbols for the jump tables, you specify a ".T"
name:
new ARMConstantPoolValue(".T", Num, ARMCP::CPDataSegmentJumpTable);
Why ".T"?
And, by the way, I noticed that you removed a "blank" comment line in
ARMISelLowering.h. I think I have done that myself, but I recently
discovered that the extra lines are intentional. Doxygen recognizes C+
