2011-10-24[powerpc] crash trying to allocate memory in inferiorJoel Brobecker2-0/+6
Our testsuite noticed a crash when trying to call a function which requires GDB to allocate memory in the inferior. Typically, this happens when one of the parameters is a string. For instance, our testcase tries: (gdb) call debug.trace (me, "You") [1] 32737 segmentation fault /path/to/gdb What happens is that GDB sees the string, and thus tries to allocate memory for it in the inferior: > /* Allocate NBYTES of space in the inferior using the inferior's > malloc and return a value that is a pointer to the allocated > space. */ > > struct value * > value_allocate_space_in_inferior (int len) > { > struct objfile *objf; > struct value *val = find_function_in_inferior ("malloc", &objf); And find_function_in_inferior first searches the symtab in case we have debug info. But, in our case (bareboard powerpc), we don't, so it gets "malloc"'s address from the minimal symbols, and builds a value whose type is a TYPE_CODE_PTR, not a TYPE_CODE_FUNC. As a result, when we later try to make the call to malloc, we end up inside the powerpc tdep code that has: > do_ppc_sysv_return_value (struct gdbarch *gdbarch, struct type *func_type, [...] > if (func_type > && TYPE_CALLING_CONVENTION (func_type) == DW_CC_GDB_IBM_OpenCL) The problem is that func_type is not a TYPE_CODE_FUNC, and thus the type-specific kind is not TYPE_SPECIFIC_FUNC, and so we do TYPE_CALLING_CONVENTION is an invalid access. Interestingly, the other call to TYPE_CALLING_CONVENTION is correctly preceded by a check of the type's TYPE_CODE (making sure that it is TYPE_CODE_FUNC). gdb/ChangeLog: * ppc-sysv-tdep.c (do_ppc_sysv_return_value): Do not check FUNC_TYPE's calling convention if FUNC_TYPE is not a function.

2011-10-21[Ada] Fix number of lines in -ada-task-info outputJoel Brobecker5-2/+165
When using the new -ada-task-info command with an argument, the output would say that there are N entries in the returned table, (where N is the total number of tasks present in the inferior). But, in fact, the table would only contain at most 1 entry. This patch fixes this by properly computing the number of tasks being displayed before giving it to the uiout. gdb/ChangeLog: * ada-tasks.c (print_ada_task_info): Fix computation of number of tasks displayed in command output. gdb/testsuite/ChangeLog: * gdb.ada/mi_task_info/task_switch.adb: New file. * gdb.ada/mi_task_info.exp: New file.
