/* 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.
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.
