/* 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 funcion
|
|
|
|
|
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.

|
|
|
|
|
|
|
|
|
|
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.
