2013-05-06darwin: warning resuming inferior after attachJoel Brobecker2-2/+33
This patch avoids a warning when resuming the execution of a program that we attached to. For instance: (gdb) attach 29989 (gdb) continue Continuing. warning: Mach error at "/[...]/darwin-nat.c:738" in function "darwin_resume_thread": (os/kern) failure (0x5) The warning is relatively harmless, but worrisome for the average user. The warning comes from the fact that darwin_wait recorded that the fake stop event corresponding to the suspend action was caused by the main thread being suspended on a SIGTRAP. As a result of this, when resuming the program's execution, we try to resume the thread's execution as well. This is where the issue occurs, as the thread was not in fact suspended, thus triggering the warning. gdb/ChangeLog: * darwin-nat.c (darwin_setup_fake_stop_event): New function. (darwin_attach): Adjust using darwin_setup_fake_stop_event.
2013-05-06darwin-nat: Print all hex values with 0x prefix.Joel Brobecker2-13/+18

2013-05-06darwin-nat.c: Do not use gdb_assert on system call outcomes.Joel Brobecker2-12/+63
There were many cases were we make a system call which could fail due to reasons outside of the debugger control. We should handle these situations a little more gracefully than triggering an internal error. gdb/ChangeLog: * darwin-nat.c (darwin_mourn_inferior): Replace call to gdb_assert by call to MACH_CHECK_ERROR. (darwin_attach_pid): Raise an error rather than a failed assertion when various system calls failed. Report a warning instead of raising a failed assertion when PREV_NOT is not NULL after call to mach_port_request_notification. (darwin_ptrace_me): Raise an error rather than a failed assertion when read returns nonzero.

2013-04-30Fix display of structures/bitfields in register description.Walfred Tedeschi5-1/+104
Add support for displaying structures and bitfields for registers when executing "maint print c-tdesc". This command is also used when converting the xml target description file into c file. Example of the behaviour is given below reporting a snipet of the xml file and a snippet of the c code generated. XML file contains: ... <union id="vecint"> <field name="v4" type="v4int8"/> <field name="v2" type="v2int16"/> </union> <struct id="struct1"> <field name="v4" type="v4int8"/> <field name="v2" type="v2int16"/> </struct> <struct id="struct2" size="8"> <field name="f1" start="0" end="34"/> <field name="f2" start="63" end="63"/> </struct> ... Setting this xml file as target description file and issuing the maintenance print c-tdesc the following output is obtained: feature = tdesc_create_feature (result, "extra"); field_type = tdesc_named_type (feature, "int8"); tdesc_create_vector (feature, "v4int8", field_type, 4); field_type = tdesc_named_type (feature, "int16"); tdesc_create_vector (feature, "v2int16", field_type, 2); type = tdesc_create_union (feature, "vecint"); field_type = tdesc_named_type (feature, "v4int8"); tdesc_add_field (type, "v4", field_type); field_type = tdesc_named_type (feature, "v2int16"); tdesc_add_field (type, "v2", field_type); C output is not supported type "struct1". This is finally the issue. 2013-03-27 Walfred Tedeschi <walfred.tedeschi@intel.com> * target-descriptions.c (maint_print_c_tdesc_cmd): Add case to parse structures as register types and bitfields. testsuite/ * gdb.xml/maint_print_struct.exp: New file. * gdb.xml/maint_print_struct.xml: New file.
