commit 2c29df25b7c2ff006b45afd80ee6dd734ebbd47c
Author: Sergio Durigan Junior <sergiodj@redhat.com>
Date: Sun Sep 11 16:53:09 2016 -0400
Fix false FAIL on gdb.base/stap-probe.exp, due to ICF optimization
GCC 6's ICF optimization pass is making the declaration of 'm1' and
'm2', on gdb.base/stap-probe.c, to be unified. However, this leads to
only one instance of the probe 'two' being created, which causes a
failure on the testsuite (which expects a multi-location breakpoint to
be inserted on the probe).
This patch fixes this failure by declaring a dummy variable on 'm1',
and using it as an argument to m1's version of probe 'two'. Since we
do not care about the contents of the functions nor about the
arguments of each probe 'two', this is OK.
gdb/testsuite/ChangeLog:
2016-09-11 Sergio Durigan Junior <sergiodj@redhat.com>
Jan Kratochvil <jan.kratochvil@redhat.com>
* gdb.base/stap-probe.c (m1): New variable 'dummy', necessary to
make m1's definition to be different from m2's. Use 'dummy' as an
argument for probe 'two'.

End of assembler dump.
The .exp patch is an obvious typo fix I think. The regex was written to
accept "ADDR in main" and I find it OK as checking .debug_line validity is not
the purpose of this testfile.
gcc-4.8.5-11.el7.x86_64 did not put the 'mov $0x0,%eax' instruction there at
all so there was no problem with .debug_line.

Fix missing files for ld when test suite not compiled in the source directory
This patch fixes an issues with six test suite expect files that do not
run correctly when the test suite is not built in the source directory. The
issue is these tests are not using the current "standard_testfile" call
but rather using the older set command to initialize the "testfile",
"srcfile" and "binprefix" variables or are missing the set for the
"binprefix" variable.

commit 981628a4af5f82a12351b9764437927d3a8c8169
Author: Tom Tromey <tom@tromey.com>
Date: Mon Oct 31 11:10:35 2016 -0600
Fix some error-handling bugs in python frame filters
While writing a Python frame filter, I found a few bugs in the current
frame filter code. In particular:
* One spot converts a Python long to a CORE_ADDR using PyLong_AsLong.
However, this can fail on overflow. I changed this to use
get_addr_from_python.
* Another spot is doing the same but with PyLong_AsUnsignedLongLong; I
changed this as well just for consistency.
* Converting line numbers can print "-1" if conversion from long
fails. This isn't fatal but just a bit ugly.
I've included a test case for the first issue. The line number one
didn't seem important enough to bother with.

get_addr_from_python. Check for errors when getting line number.
