2011-01-13[ia64-hpux] inferior function call supportJoel Brobecker1-0/+6
We have two stacks to deal with on ia64, when making a function call. The first is the usual stack frame, and the second is the register stack frame. On ia64-linux, the register frame is setup by adjusting the BSP register. Unfortunately for us, the HP-UX kernel does not allow the debugger to change the value of the BSP. To work around that limitation, the method I am using here is to push some assembly code on the stack. This assembly code contains, among other things, a call to the alloc insn, which sets up our frame for us. An extensive comment in ia64-hpux-tdep.c explains the entire procedure. Despite this approach, most of the code in ia64-tdep.c which sets up the function call is still applicable - and only a few things need to be done differently: For instance, instead of changing the BSP, we do nothing. We store the parameters at a different location, etc. So this patch also adjusts the inf-call code in ia64-tdep.c to make it a little more extensible: I create a new ia64_infcall_ops structure which allows an ABI to define how the few things that need to be differentiated. Another element that turned out to be necessary but is more of a detail is that the computation of the linkage pointer needs to be handled specially for symbols inside shared libraries. This is especially visible when calling malloc, which happens everytime memory needs to be allocated in inferior memory... The special treatment included again the necessity to use some routines only available on the host. So another target object TARGET_OBJECT_HPUX_SOLIB_GOT was created for that purpose. gdb/ChangeLog: * ia64-tdep.h (struct regcache): Forward declare. (struct ia64_infcall_ops): New struct type. (struct gdbarch_tdep): New fields "find_global_pointer_from_solib" and "infcall_ops". * ia64-tdep.c (ia64_find_global_pointer_from_dynamic_section): Renames ia64_find_global_pointer.

2011-01-13[ia64-hpux] unwinding bsp value from system callJoel Brobecker1-0/+3
This fixes unwinding from a thread that is stopped inside a system call. This can be seen when switching to a thread that is stopped doing a pthread_cond_wait, for instance... The comments inside the code should explain what is happening in our case (the HP-UX exception in the case of system calls): Under certain circumstances (program stopped inside syscall), the offset to apply to the current BSP in order to compute the previous BSP is not the usual CFM & 0x7f. We parts in this patch: 1. Figuring out that we are stopped inside a syscal: This requires a TT_LWP_RUREGS ttrace call, which is not directly possible from ia64-tdep.c. So use defined a new TARGET_OBJECT_HPUX_UREGS object to request it from the -nat side. 2. Add a gdbarch_tdep method that allows us to change the default behavior on ia64-hpux, permitting us to have a different "size of register frame" in that one particular case. gdb/ChangeLog: * target.h (enum target_object): Add TARGET_OBJECT_HPUX_UREGS. * ia64-tdep.h (struct frame_info): forward declaration. (struct gdbarch_tdep): Add field size_of_register_frame. * ia64-tdep.c (ia64_access_reg): Use tdep->size_of_register_frame to determine the size of the register frame.

2010-05-17Add reset_schedlock declaration in target.h.Joel Brobecker1-0/+2
This patches improves a couple of previous patches: - one that introduces reset_schedlock, but failed to add a declarationl; - one that was checked in to avoid a compilation failure due to that missing declaration. It also improves the declaration itself to better conform to our coding practices. Same for the comments. 2010-05-17 Joel Brobecker <brobecker@adacore.com> * target.h (reset_schedlock): Add declaration. * infrun.c (reset_schedlock): Add missing void in function profile. * target.c (target_mourn_inferior): Delete local declaration of reset_schedlock.
