/* Test the behaviour of gdb in the following situation, the dwarf debug
   information describes a parameter as being in a register but a more
   recent (inner) frame marks the register as being undefined.

   This can arrise if the dwarf producer has the location of a parameter in
   a callee clobbered register at the time of a call.  Older versions of
   gcc used to do this, newer versions seem to avoid this issue.

   Though it could be argued that such dwarf is incorrect, we would still
   like gdb to behave in a user friendly, and helpful way when presented
   with such dwarf.  */

/* There are 4 test cases in this assembler file.  In each case function
   main calls each test function in turn, each test case then calls the
   breakpt function.

   We don't actually pass any parameters around, we don't need to, instead
   the dwarf for each test function declares that the function has some
   parameters, and tells us which registers these parameters are in.  The
   breakpt function marks some of these registers as undefined.  The main
   function helpfully places some marker values into all the registers that
   are used as parameters so we can see if they ever get printed.

   We use gdb to break in the breakpt function for each of the 4 test
   cases, and then backtrace through the test function back to main.  In
   each case some or all of the parameters to the test function should be
   marked as optimized out, due to the breakpt function effectively
   clobbering them.

   The dwarf register numbering is different to the gdb register number.
   In some of the tests we rely on gdb behaviour of being able to specify a
   struct using a single register location, the structure will then "flow"
   into the next gdb register.  The initial register is specified using a
   dwarf register number, but the "next" register will depend on gdb
   register ordering.

   Exposing this internal gdb register numbering is really a gdb bug, the
   functionality for selecting the "next" register should be moved into
   target dependent code (such as AVR).  Right now we work around this
   bug in this test; if the bug is ever fixed this test is going to need
   some tweaking.

   The breakpt function always marks rcx, rsi, and rdi as undefined.

      register | dwarf | gdb   |         |
      name     | reg # | reg # | breakpt |
     ----------|-------|-------|---------|
        rdx    | 1     | 3     |         |
        rcx    | 2     | 2     | undef   |
        rbx    | 3     | 1     |         |
        rsi    | 4     | 4     | undef   |
        rdi    | 5     | 5     | undef   |

   We declare the test parameters to be in the register rdx, rcx, rbx, rsi,
   and rdi.  Of these, rdx and rbx are not traditionally used for parameter
   passing, but that really doesn't matter for this test.

   int_param_single_reg_loc: Passes 8-byte integer parameters in 8-byte
                             registers using DW_OP_regn style location
                             information.  The parameters are placed as
                             follows, operand0 (rcx), operand1 (rbx),
                             operand2 (rsi).  We expect operand0 and
                             operand2 to be marked as optimised out, but
                             operand1 to be valid.

   struct_param_single_reg_loc: Passes 16-byte structures in two 8-byte
                                registers using dwarf DW_OP_regn location
                                information to describe a single register,
                                gdb will assume that the structure flows
                                into the next sequential register.  The
                                parameters are placed as follows, operand0
                                (rbx/rcx), operand1 (rcx/rdx), and operand2
                                (rsi/rdi).  The reuse of rcx between
                                operand0 and operand1 is intentional.

   struct_param_two_reg_pieces: Passes 16-byte structure in two 8-byte
                                registers using dwarf DW_OP_piece based
                                location information to describe both
                                registers.  The parameters are placed as
                                follows, operand0 (rdx/rcx), operand1
                                (rcx/rbx), and operand2 (rsi/rdi).  The
                                reuse of rcx between operand0 and operand1
                                is intentional.

   int_param_two_reg_pieces: Passes 8-byte integer values in two 8-byte
                             registers with 4-bytes being placed in each
                             register, using dwarf DW_OP_piece based
                             location information to describe how the
                             parameters are split up.The parameters are
                             placed as follows, operand0 (rdx/rcx),
                             operand1 (rcx/rbx), and operand2 (rsi/rdi).
                             The reuse of rcx between operand0 and operand1
                             is intentional.
