Builder.position_at_beginning segfaults when called on empty basic block #10

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. create an empty basic block
2. create a Builder instance
3. call builder.position_at_beginning with the empty block
Or just apply the attached patch to testall.py

What is the expected output? What do you see instead?
Expected: Internal check if block is empty, then noop instead of
positioning before a non existing instruction
I get: segfault

What version of the product are you using? On what operating system?
subversion trunk r44, Ubuntu 8.04
