Walfred Tedeschi	3f2f6cb5e8	Adaptation of siginfo fixup for the new bnd fields New bnds fields will be always present for x86 architecture. 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. 2016-02-02 Walfred Tedeschi <walfred.tedeschi@intel.com> gdb/ChangeLog: * amd64-linux-siginfo.c (nat_siginfo_t, nat_sigval_t, nat_timeval): New types.

Andrew Burgess	37a8db1a33	gdb: Guard against undefined behaviour in mi-vla-fortran.exp 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.	10 years ago
Andrew Burgess	5fdf6324fa	gdb: New set/show max-value-size command. 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. gdb/ChangeLog: * value.c (max_value_size): New variable. (MIN_VALUE_FOR_MAX_VALUE_SIZE): New define. (show_max_value_size): New function. (check_type_length_before_alloc): New function. (allocate_value_contents): Call check_type_length_before_alloc.

Kevin Buettner	94715c1790	rx: Treat scalars larger than 8 bytes as aggregates in rx_push_dummy_call. This patch fixes the following failures (which are also GDB internal errors) for the -m64bit-doubles multilib: FAIL: gdb.base/callfuncs.exp: p t_double_complex_values(dc1, dc2) (GDB internal error) FAIL: gdb.base/callfuncs.exp: p t_double_complex_values(dc3, dc4) (GDB internal error) FAIL: gdb.base/callfuncs.exp: p t_double_complex_many_args(dc1, dc2, dc3, dc4, dc1, dc2, dc3, dc4, dc1, dc2, dc3, dc4, dc1, dc2, dc3, dc4) (GDB internal error) FAIL: gdb.base/callfuncs.exp: p t_double_complex_many_args(dc1, dc1, dc1, dc1, dc1, dc1, dc1, dc1, dc1, dc1, dc1, dc1, dc1, dc1, dc1, dc1) (GDB internal error) FAIL: gdb.base/callfuncs.exp: p t_long_double_complex_values(ldc1, ldc2) (GDB internal error) FAIL: gdb.base/callfuncs.exp: p t_long_double_complex_values(ldc3, ldc4) (GDB internal error) FAIL: gdb.base/callfuncs.exp: p t_long_double_complex_many_args(ldc1, ldc2, ldc3, ldc4, ldc1, ldc2, ldc3, ldc4, ldc1, ldc2, ldc3, ldc4, ldc1, ldc2, ldc3, ldc4) (GDB internal error) FAIL: gdb.base/callfuncs.exp: p t_long_double_complex_many_args(ldc1, ldc1, ldc1, ldc1, ldc1, ldc1, ldc1,ldc1, ldc1, ldc1, ldc1, ldc1, ldc1, ldc1, ldc1, ldc1) (GDB internal error) FAIL: gdb.base/callfuncs.exp: noproto: p t_double_complex_values(dc1, dc2) (GDB internal error) FAIL: gdb.base/callfuncs.exp: noproto: p t_double_complex_values(dc3, dc4) (GDB internal error) FAIL: gdb.base/callfuncs.exp: noproto: p t_double_complex_many_args(dc1, dc2, dc3, dc4, dc1, dc2, dc3, dc4, dc1, dc2, dc3, dc4, dc1, dc2, dc3, dc4) (GDB internal error) FAIL: gdb.base/callfuncs.exp: noproto: p t_double_complex_many_args(dc1, dc1, dc1, dc1, dc1, dc1, dc1, dc1, dc1, dc1, dc1, dc1, dc1, dc1, dc1, dc1) (GDB internal error) FAIL: gdb.base/callfuncs.exp: noproto: p t_long_double_complex_values(ldc1, ldc2) (GDB internal error) FAIL: gdb.base/callfuncs.exp: noproto: p t_long_double_complex_values(ldc3, ldc4) (GDB internal error) FAIL: gdb.base/callfuncs.exp: noproto: p t_long_double_complex_many_args(ldc1, ldc2, ldc3, ldc4, ldc1, ldc2, ldc3, ldc4, ldc1, ldc2, ldc3, ldc4, ldc1, ldc2, ldc3, ldc4) (GDB internal error) FAIL: gdb.base/callfuncs.exp: noproto: p t_long_double_complex_many_args(ldc1, ldc1, ldc1, ldc1, ldc1, ldc1, ldc1,ldc1, ldc1, ldc1, ldc1, ldc1, ldc1, ldc1, ldc1, ldc1) (GDB internal error) FAIL: gdb.base/varargs.exp: print find_max_double_real(4, dc1, dc2, dc3, dc4) (GDB internal error) FAIL: gdb.base/varargs.exp: print find_max_long_double_real(4, ldc1, ldc2, ldc3, ldc4) (GDB internal error) The assertion failure which is tripped is: gdb_assert (arg_size <= 4); While it may seem that the patch ought to disallow scalars larger than 4, scalars of size 8 are explicitly handled by the code elsewhere. This came up because gcc has a complex type that is 16 bytes in length when 64-bit doubles are used. gdb/ChangeLog: * rx-tdep.c (rx_push_dummy_call): Treat scalars larger than 8 bytes as aggregates.	10 years ago

Yao Qi	4d18591be9	Remove argument pc in get_next_pcs Nowadays, get_next_pcs in linux_target_ops has two parameters PC and REGCACHE. Parameter PC looks redundant because it can be go from REGCACHE. The patch is to remove PC from the arguments for various functions. gdb: 2016-01-26 Yao Qi <yao.qi@linaro.org> * arch/arm-get-next-pcs.c (thumb_deal_with_atomic_sequence_raw): Remove argument pc. Get pc by regcache_read_pc. Callers updated. (arm_deal_with_atomic_sequence_raw): Likewise. (thumb_get_next_pcs_raw): Likewise. (arm_get_next_pcs_raw): Likewise. (arm_get_next_pcs): Remove argument pc. Callers updated. * arch/arm-get-next-pcs.h (arm_get_next_pcs): Update declaration. gdb/gdbserver: 2016-01-26 Yao Qi <yao.qi@linaro.org> * linux-arm-low.c (arm_gdbserver_get_next_pcs): Remove argument pc. * linux-low.c (install_software_single_step_breakpoints): Don't call regcache_read_pc. * linux-low.h (struct linux_target_ops) <get_next_pcs>: Remove argument pc.	10 years ago
