The .md file defines ( mandatory ) "indirect_jump" which allows ( a certain kind of ) register as parameter. What is missing?
Either the pattern doesn't match indirect_jump, or the instruction
predicate returns zero, or the operand predicate returns zero.
Beyond that we don't have enough information to say.

Is there a way to find out what was the pattern? And if the operand predicate fails, shouldn't gcc attempt to reassign the ( register , "(reg:SI 52)" ) operand in order to satisfy the predicate?
