BASEDIR was added by https://sourceware.org/ml/gdb-patches/2013-10/msg00587.html
in order to handle the different directory layout in serial testing
and parallel testing. BASEDIR is "gdb.base" in serial testing and is
"outputs/gdb.base/TESTNAME" in parallel testing. However, it doesn't
work if the GDBserver is in remote target, like this,
$ make check RUNTESTFLAGS='--target_board=remote-gdbserver-on-localhost foll-vfork.exp foll-exec.exp'
FAIL: gdb.base/foll-exec.exp: continue to first exec catchpoint (the program exited)
FAIL: gdb.base/foll-vfork.exp: exec: vfork and exec child follow, to main bp: continue to bp (the program exited)
FAIL: gdb.base/foll-vfork.exp: exec: vfork child follow, finish after tcatch vfork: finish (the program exited)
FAIL: gdb.base/foll-vfork.exp: exec: vfork relations in info inferiors: continue to bp (the program exited)
these tests fail because the executable can't be found. With target
board native-gdbserver, the program is spawned this way,
spawn ../gdbserver/gdbserver --once :2347 /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/gdb.base/foll-vfork
so BASEDIR is correct. However, with target board
remote-gdbserver-on-localhost, the program is spawned
spawn /usr/bin/ssh -l yao localhost /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/../gdbserver/gdbserver --once :2346 /scratch/yao/gdb/build-git/x86_64/gdb/testsuite/gdb.base/foll-vfork
so BASEDIR (either "gdb.base" or "outputs/gdb.base/TESTNAME") makes no
sense.
I had a fix that pass absolute directory to BASEDIR, but it assumes
that directory structure is the same on build and target, and it
doesn't work in remote host case. The current fix in this patch is
to get the directory from argv[0]. In any case, the program to be
exec'ed is at the same directory with the main program.
Note that these tests do "next N" to let program stop at the desired
line, but it is fragile, because GDB for different targets may skip
function prologue slightly differently, so I replace some of them by
"tbreak on LINE NUMBER and continue".

This change makes gas's notion of the msp430 dwarf2 address size match
that of gcc and gdb. This is needed so that the format of addresses
generated for DW_LNE_set_address in .debug_line will match the address
size for the compilation unit.
In gcc/config/msp430/msp430.h, it's set to 4:
#define DWARF2_ADDR_SIZE 4
Likewise in gdb/msp430-tdep.c:
set_gdbarch_dwarf2_addr_size (gdbarch, 4);
(As far as I can tell, however, GDB doesn't use this value when decoding
.debug_line. Instead, GDB uses the Pointer Size from the compilation
unit.)
readelf is able to seamlessly handle mismatches between these various
sizes by using the size of the DW_LNE_set_address instruction to
determine the address size. Another way to fix this problem is to
make GDB behave in a similar manner. In my opinion, GDB should detect
and inform the user about these mismatches; it's not clear to me if
it's correct for GDB to go ahead and read the address anyway when a
size mismatch is detected.
Without this change, addresses in .debug_line are encoded in two bytes
for some multilibs. When GDB reads the address for
DW_LNE_set_address, it uses the pointer size provided by the CU. When
these values don't match, GDB reads the wrong number of bytes. In the
cases that I've looked at, GDB is reading 4 bytes from a 2 byte
container, which results in a garbage address. GDB discards lines
which have a bogus address; the end result is that GDB records no line
number information for CUs which have a mismatch between the address
size (from the CU) and the format of the address used by
DW_LNE_set_address.

The calculation of the shift amount, used to insert fields into the
instruction buffer, is not correct when the following conditions are all
true:
- CGEN_INT_INSN_P is defined, and true.
- CGEN_INSN_LSB0_P is true
- Total instruction length is greater than the length of a single
instruction word (the instruction is made of multiple words)
- The word offset is non-zero (the field is outside the first word)
When the above conditions are all true, the calculated shift fails to
take account of the total instruction length.
After this commit the calculation of the shift amount is split into two
parts, first we calculate the shift required to get to BIT0 of the word
in which the field lives, then we calculate the shift required to place
the field within the instruction word.
The change in this commit only effects the CGEN_INT_INSN_P defined true
case, but changes the code for both CGEN_INSN_LSB0_P true, and false.
In the case of CGEN_INSN_LSB0_P being false, the code used to say:
shift = total_length - (word_offset + start + length);
Now it says:
shift_to_word = total_length - (word_offset + word_length);
shift_within_word = word_length - start - length;
shift = shift_to_word + shift_within_word;
From which we can see that in all cases the computed shift value should
be unchanged.
In the case of CGEN_INSN_LSB0_P being true, the code used to say:
shift = (word_offset + start + 1) - length;
Now it says:
shift_to_word = total_length - (word_offset + word_length);
shift_within_word = start + 1 - length;
shift = shift_to_word + shift_within_word;
In the case where 'total_length == word_length' AND 'word_offset ==
0' (which indicates an instruction of a single word), we see that the
computed shift value will be unchanged. However, when the total_length
and word_length are different, and the word_offset is non-zero then the
computed shift value will be different (and correct).

In commit 02a79b89fd some of the load
instructions with a zero offset (where the offset is not mentioned) were
marked as NO-DIS, meaning that the disassembler must display the offset,
even though it is zero.
This change seems a little strange to me as it was only applied to some
loads, not all, and the same change was not applied to the stores.
However, I'm reluctant to revert a specific change to the assembler,
when the output is obviously correct. With this commit then I simply
bring the expected assembler test results into line with what is
actually produced.

Fixup for compatibility layer 32bits has to be fixed.
It was added the nat_siginfo to serving as intermediate step
between kernel provided siginfo and the fix up routine.
When executing compat_siginfo_from_siginfo or
compat_x32_siginfo_from_siginfo first the buffer read from the kernel are
converted into the nat_signfo for homogenization, then the fields of
nat_siginfo are use to set the compat and compat_x32 siginfo fields.
In other to make this conversion independent of the system where gdb
is compiled the most complete version of the siginfo, named as native
siginfo, is used internally as an intermediate step.
Conversion using nat_siginfo is exemplified below:
compat_siginfo_from_siginfo or compat_x32_siginfo_from_siginfo:
buffer (from the kernel) -> nat_siginfo -> 32 / X32 siginfo
(memcpy) (field by field)
siginfo_from_compat_x32_siginfo or siginfo_from_compat_siginfo:
32 / X32 siginfo -> nat_siginfo -> buffer (to the kernel)
(field by field) (memcpy)
Caveat: No support for MPX on x32.

The test gdb.mi/mi-vla-fortran.exp reveals an issue with the DWARF
generated by gfortran.
In the test a pointer variable 'pvla2' is created:
real, pointer :: pvla2 (:, :)
Initially this variable will be unassociated, so something like this:
l = associated(pvla2)
should return false.
In the test gdb stops at a point _before_ pvla2 is associated with
anything, and we then try to print pvla2, the expectation is that gdb
should reply <not associated>.
The problem is that the data the DWARF directs gdb to read (to identify
if the variable is associated or not) is not initialised until the first
time pvla2 is accessed.
As a result gdb ends up reading uninitialised memory, sometimes this
uninitialised memory indicates the variable is associated (when it's
not). This first mistake can lead to a cascade of errors, reading
uninitialised memory, with the result that gdb builds an invalid type to
associate with the variable pvla2.
In some cases, this invalid type can be very large, which when we try to
print pvla2 causes gdb to allocate a large amount of memory.
A recent commit added a new gdb variable 'max-value-size', which
prevents gdb from allocating values of extreme size. As a result
directly trying to print pvla2 will now now error rather than allocate a
large amount of memory.
However, some of the later tests create a varobj for pvla2, and then
ask for the children of that varobj to be displayed. In the case where
an invalid type has been computed for pvla2 then the number of children
can be wrong, and very big, in which case trying to display all of these
children can cause gdb to consume an excessive amount of memory.
This commit first detects if printing pvla2 triggers the max-value-size
error, if it does then we avoid all the follow on tests relating to the
unassociated pvla2, which avoids the second error printing the varobj
children.
gdb/testsuite/ChangeLog:
* gdb.mi/mi-vla-fortran.exp: Add XFAIL for accessing unassociated
pointer. Don't perform further tests on the unassociated pointer
if the first test fails.
For languages with dynamic types, an incorrect program, or uninitialised
variables within a program, could result in an incorrect, overly large
type being associated with a value. Currently, attempting to print such
a variable will result in gdb trying to allocate an overly large buffer.
If this large memory allocation fails then the result can be gdb either
terminating, or (due to memory contention) becoming unresponsive for the
user.
A new user visible variable in gdb helps guard against such problems,
two new commands are available:
set max-value-size
show max-value-size
The 'max-value-size' is the maximum size of memory in bytes that gdb
will allocate for the contents of a value. Any attempt to allocate a
value with a size greater than this will result in an error. The
initial default for this limit is set at 64k, this is based on a similar
limit that exists within the ada specific code.
It is possible for the user to set max-value-size to unlimited, in which
case the old behaviour is restored.
