2015-07-03Change the meaning of 'x' in a transformationBjörn Gustavsson
The purpose of this series of commits is to improve code generation for the Clang compiler. As a first step we want to change the meaning of 'x' in a transformation such as: operation Literal=q => move Literal x | operation x Currently, a plain 'x' means reg[0] or x(0), which is the first element in the X register array. That element is distinct from r(0) which is a variable in process_main(). Therefore, since r(0) and x(0) are currently distinct it is fine to use x(0) as a scratch register. However, in the next commit we will eliminate the separate variable for storing the contents of X register zero (thus, x(0) and r(0) will point to the same location in the X register array). Therefore, we must use another scratch register in transformation. Redefine a plain 'x' in a transformation to mean x(1023). Also define SCRATCH_X_REG so that we can refer to the register by name from C code.

2015-07-03beam_makeops: Eliminate crash because of unsafe packingBjörn Gustavsson
Consider an hypothetical instruction: do_something x x c The loader would crash if we tried to load an instance of the instruction with the last operand referencing a literal: {do_something,{x,0},{x,1},{literal,{a,b,c}}} Teach beam_makeops to turn off packing for such unsafe instructions.

2015-07-02Add a smoke test of erts_debug:df/1Björn Gustavsson
Run erts_debug:df/1 for all loaded modules. On my reasonably fast, modern computer this test case runs in approximately 10 seconds. To avoid spending many minutes running this test case on older computers, limit the running time to 20 seconds. While we are at it, remove all ?line macros.

causing the delete marked object to be left in the table after safe_fixtable(_,false) has returned. This is not super serious as the delete marked object is quite benign and will be deleted at the next unfix operation.
