1993-04-23 * Merge in HPPA/BSD patches from Utah:Stu Grossman1-938/+0
* defs.h: Add const to 2nd arg of psignal prototype. * hppah-tdep.c: Renamed to hppa-tdep.c 'cuz it's common code with BSD now. * hppab-core.c: Deleted. No longer useful. * hppab-nat.c: #include more files. Use PT_WUREGS, not PT_WRITE_U. * hppab-tdep.c: Deleted. Supplanted by hppa-tdep.c. * config/pa/hppabsd.mh (NATDEPFILES): Remove hppab-core.o. * config/pa/hppabsd.mt (TDEPFILES): hppab-tdep.o => hppa-tdep.o * config/pa/hppahpux.mt (TDEPFILES): hppab-tdep.o => hppa-tdep.o * config/pa/xm-hppab.h: #define SET_STACK_LIMIT_HUGE.
1993-04-23 * Fix two bugs found by deja-gnu. One is the incorrect reportingStu Grossman1-10/+61
of the PC being in a stack dummy when looking at a core file without symbols. The other is the incorrect passing of char arguments during expression evaluation (ie: p foo('a','b') would mess up the passing of it's args because it wasn't coercing the char's to ints). * hppah-tdep.c: Rename global functions to have consistent hppa_ prefix. Make more functions static. Drop hp_ prefix from static functions. (hppa_push_arguments): Call value_arg_coerce to cast char to int args if necessary. (hppa_fix_call_dummy): Create this routine from FIX_CALL_DUMMY macro in tm-hppa.h. * inferior.h (PC_IN_CALL_DUMMY): Check for frame_address being valid (ie: != 0) before doing comparison against PC. * valops.c (call_function_by_hand): Adjust call to FIX_CALL_DUMMY to reflect new arguments. * config/pa/tm-hppa.h (POP_FRAME, PUSH_ARGUMENTS): Use new hppa_ prefix for func name. (FIX_CALL_DUMMY): Move code into hppah-tdep.c. * testsuite/gdb.t16/gdbme.c, testsuite/gdb.t17/gdbme.c: Add calls to malloc() so that we can test GDB eval of dynamically created arrays (like char strings in `print "foo"').
1993-01-15 * hppa-pinsn.c (print_insn): Use read_memory_integer, instead ofStu Grossman1-35/+40
read_memory to get byte order right. * hppah-tdep.c (find_unwind_info): Don't read in unwind info anymore. This is done in paread.c now. We expect unwind info to hang off of objfiles, and search all of the objfiles when until we find a match. * (skip_trampoline_code): Cast arg to target_read_memory. * objfiles.h (struct objfile): Add new field obj_private to hold per object file private data (unwind info in this case). * paread.c (read_unwind_info): New routine to read unwind info for the objfile. This data is hung off of obj_private. * tm-hppa.h: Define struct obj_unwind_info, to hold pointers to the unwind info for this objfile. Also define OBJ_UNWIND_INFO to make this easier to access.
1993-01-10 * blockframe.c (frameless_look_for_prologue): Correct theStu Grossman1-107/+158
comment. * gdbtypes.h, gdbtypes.c: Use const in decl of cplus_struct_default, now that pa-gas assembler has been fixed. * hppah-nat.c: Formatting. * hppah-tdep.c: Remove lots of useless externs for variables we don't use. * (find_unwind_entry): Speed up by using binary search, and a one entry cache. * (rp_saved): New routine to see what unwind info says about RP being saved on the stack frame. * (frame_saved_pc): Look for prologue to see if we need to examine the stack for the saved RP or not. * (init_extra_frame_info): Check for prologue, instead of framesize to determine if we are frameless or not. * (frame_chain_valid): Stop backtraces when we run into _start. * (push_dummy_frame): Reformat to make more readable. * (find_dummy_frame_regs): ditto. * (hp_pop_frame): ditto. * (hp_restore_pc_queue): small cleanup. * (hp_push_arguments): ditto. * (pa_do_registers_info): ditto. * (skip_prologue): New routine created from SKIP_PROLOGUE macro. * tm-hppa.h: Move contents of SKIP_PROLOGUE into hppah-tdep.c. * Define FRAME_CHAIN_VALID. * Turn on BELIEVE_PCC_PROMOTION so that we can access char args passed to functions. * paread.c (pa_symtab_read): Use new bfd conventions for accessing linker symbol table. * (pa_symfile_init): Access embedded STAB info via BFD section mechanism and related macros.
1992-12-29 * hppah-tdep.c (skip_trampoline_code): Use new macros forStu Grossman1-2/+2
accessing minimal symbol data. * infcmd.c (read_pc): Use #ifdef, not #if. * symfile.c (syms_from_objfile): Add CONST to decl for targets. * tm-hppa.h (FIX_CALL_DUMMY): Use new macros for accessing minimal symbol data.
1992-12-28 * hppah-tdep.c (frame_saved_pc): Use better test for outermostStu Grossman1-17/+198
frame. Use find_return_regnum to find the caller. * (find_unwind_entry): New routine to locate stack frame info associated with a procedure. This looks in the $UNWIND_START$ section in the SOM file. * (find_return_regnum): New routine. Uses find_unwind_entry() to figure out where the caller's return address is stored. * (find_proc_framesize): New routine. Uses find_unwind_entry() to figure out the frame size for a procedure. * (saved_pc_after_call): New routine, moved from tm-hppa.h. * (init_extra_frame_info): New routine. Corrects PC and FP for outermost frame if necessary. * (frame_chain): New routine, moved from tm-hppa.h. * (skip_trampoline_code): Handle computed function calls (ie: calls from $$dyncall). * (unwind_command): Temporary support function to allow user to control/observe aspects of the unwind (stack frame) info. * infcmd.c (read_pc): (Temporary), put a hack in to see if the PC was in a system call, if so, then read the PC from r31. * tm-hppah.h (SKIP_TRAMPOLINE_CODE, IN_SOLIB_TRAMPOLINE): Deal with extra arg for skip_trampoline_code(). * (INIT_EXTRA_FRAME_INFO): Define to point at subr (see above). * (FRAME_CHAIN, FRAME_CHAIN_VALID): Turn into real subroutines. * tm-hppa.h (SAVED_PC_AFTER_CALL): Turn into real subroutine.
1992-12-22 * hppa-pinsn.c (print_insn): Improve handling of be and bleStu Grossman1-954/+179
branch targets to compute target address using const from previous instruction if necessary. * Add `Q' operator to print out bit position field various instructions. * hppah-nat.c: #include sys/param.h, and sys/user.h. General cleanups, use new code from Utah. * (store_inferior_registers): Update to new code from Utah. * (initialize_kernel_u_addr): Re-enable decl of struct user u. * (fetch_register): Clear out priv level when reading PCs. * hppah-tdep.c: Get rid of gobs of KERNELDEBUG stuff. * Remove decl of errno, #include wait.h and target.h. * (frame_saved_pc): Check `flags' pseudo-register to see if we were inside of a kernel call. If so, then PC is in a different register. Also, mask out bottom two bits of all PCs so as not to confuse higher level code. * (push_dummy_frame): Create from #define in tm-hppa.h. * (find_dummy_frame_regs): Update from Utah. * (hp_pop_frame): Create from #define in tm-hppa.h. * (hp_restore_pc_queue): New, from Utah. * (hp_push_arguments): Big fixes from Utah. * (pa_do_registers_info, pa_print_registers): Only print out fp regs upon request. * (skip_trampoline_code): New routine to deal with stubs that live in nowhereland between callers and callees. * i860-tdep.c: Remove decl of attach_flag. * infrun.c (wait_for_inferior): Add new macro INSTRUCTION_NULLIFIED, which can tell if the instruction pointed at by PC will be nullified. If so, then step the target once more so as to avoid confusing the user. * (just before step_over_function:): Use stop_func_start, not stop_pc when checking for the existance of line number info. stop_func_start will reflect the proper address of the target routine, not of the stub that we may be traversing to get there. * tm-hppa.h: define SKIP_TRAMPOLINE_CODE and IN_SOLIB_TRAMPOLINE to deal with the stubs that PA compilers sometimes stick between callers and callees. Also, define FLAGS_REGNUM for access to the `flags' pseudo-reg. * (REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Use memcpy, not bcopy. * (CANNOT_STORE_REGISTER): New from Utah. Says that we can't write gr0, PC regs, and PSW! * (FRAME_FIND_SAVED_REGS): Bug fixes from Utah. * (PUSH_DUMMY_FRAME, POP_FRAME): Make into real routines in hppah-nat.c. * (CALL_DUMMY, FIX_CALL_DUMMY): Fixes from Utah. * Define struct unwind_table_entry. * valops.c (call_function_by_hand): Add another arg to FIX_CALL_DUMMY (under #ifdef GDB_TARGET_IS_HPPA). Why is this necessary?
1992-12-15* convex-xdep.c, hppab-nat.c, i860-tdep.c, infptrace.c: RemoveStu Grossman1-2/+1
decl for attach_flag, it now lives in inferior.h. * hppa-pinsn.c: Reformat opcode tables. Add function prototypes. Make most functions static. * hppah-nat.c: General cleanups, remove BSD specific code (since that all lives in hppab-nat.c). * hppah-tdep.c (frame_chain_valid), tm-hppa.h (FRAME_CHAIN): Change sense of test against inside_entry_file(). This fix is from U. of Utah. * tm-hppa.h (PUSH_DUMMY_FRAME, POP_FRAME): Use char * for 2nd arg to read/write_register_bytes().
