Thu Jul 25 19:41:31 1996 Fred Fish <fnf@cygnus.com> for a rather huge set of changes. I was going to put them here, but it made cvs dump core. :-(
1996-05-26 Changes from: David Mosberger-Tang <davidm@azstarnet.com>Fred Fish1-21/+126
* NEWS: Add Alpha Linux as a new native configuration. * mdebugread.c (parse_symbol): When we find a malloc() symbol with return type VOID, assume no debugging info is available for that object file and patch the return value into VOID *. Otherwise, operations requiring an implicit call to malloc() will fail. * infrun.c (wait_for_inferior): The criterion to detect entering a sigtramp handler is now: (a) the current pc is inside a sigtramp handler, (b) the previous pc is not in a sigtramp handler, and (c) the current stack pointer is "inner" than the old one. Condition (c) is new to avoid mistaking a return from a signal handler into sigtramp as a new sigtramp invocation. * dcache.c (struct dcache_block): Declare addr as CORE_ADDR. An int may not be big enough to hold an address. (dcache_hit): Ditto. (dcache_peek_byte): Fix indentation. * configure.in (alpha-*-linux*): Add target. * configure: Rebuild * config/alpha/tm-alpha.h (PROC_DESC_IS_DYN_SIGTRAMP): New macro. (SET_PROC_DESC_IS_DYN_SIGTRAMP): Ditto. (DYNAMIC_SIGTRAMP_OFFSET): Ditto. (SIGCONTEXT_ADDR): Ditto. (FRAME_PAST_SIGTRAMP_FRAME): Ditto. * config/alpha/alpha-linux.mh: New file. * config/alpha/alpha-linux.mt: Ditto. * config/alpha/nm-linux.h: Ditto. * config/alpha/tm-alphalinux.h: Ditto. * config/alpha/xm-alphalinux.h: Ditto. * config/alpha/xm-alphaosf.h: Renamed from xm-alpha.h. * config/alpha/alpha-osf1.mh (XM_FILE): Change from xm-alpha.h to xm-alphaosf.h. * config/alpha/alpha-osf2.mh: Ditto. * blockframe.c (find_pc_partial_function): Pass PC to SIGTRAMP_START and SIGTRAMP_END macros for the benefit of systems that detect sigtramp code via designated code sequences (as is the case for Linux/Alpha, for example). * config/i386/tm-i386bsd.h: Change SIGTRAMP_START and SIGTRAMP_END to ignore new PC argument. * config/m68k/tm-hp300bsd.h: Ditto. * config/vax/tm-vax.h: Ditto. * alpha-tdep.c (alpha_linux_sigtramp_offset): New function. (alpha_osf_skip_sigtramp_frame): Ditto. (push_sigtramp_desc): Ditto. (alpha_find_saved_regs): Use SIGCONTEXT_ADDR macro to extract sigcontext address from frame. (alpha_saved_pc_after_call): When in sigtramp, use alpha_frame_saved_pc() instead of read-register(). (after_prologue): When inside a dynamically generated sigtramp function, there is no prologue, so return address of first instruction. (alpha_in_prologue): Fix typo in comment. (find_proc_desc): Use macro DYNAMIC_SIGTRAMP_OFFSET to determine whether we're inside a dynamicaly generated sigtramp function. If so, create and push and appropriate procedure descriptor. (alpha_frame_chain): Use macro FRAME_PAST_SIGTRAMP_FRAME to obtain the frame past a sigtramp frame (if the current frame is indeed a sigtramp function). (init_extra_frame_info): Don't read next frame register off of stack-pointer when inside a dynamiccaly generated sigtramp. (alpha_pop_frame): Also unlink and destroy procedure descriptors created for dynamically generated sigtramp functions. * alpha-nat.c: When compiling under Linux, include <asm/reg.h> and <alpha/ptrace.h> instead of <machine/reg.h>
1995-12-02 * alpha-tdep.c (heuristic_proc_desc): Add heuristic toPeter Schauer1-1/+53
determine the return address register, needed for OSF/1-3.2C. * config/alpha/tm-alpha.h (T7_REGNUM, T9_REGNUM): Define.

and CORE_ADDR, respectively. * frame.h (FRAME, FRAME_INFO_ID, FRAME_ADDR): Remove. * blockframe.c (get_frame_info): Remove. * a29k-tdep.c, alpha-tdep.c, blockframe.c, breakpoint.c, breakpoint.h, energize.c, findvar.c, gdbtk.c, gould-pinsn.c, h8300-tdep.c, h8500-tdep.c, hppa-tdep.c, i386-tdep.c, i960-tdep.c, infcmd.c, inferior.h, infrun.c, m68k-tdep.c, m88k-tdep.c, mips-tdep.c, nindy-tdep.c, printcmd.c, pyr-tdep.c, rs6000-tdep.c, sh-tdep.c, sparc-tdep.c, stack.c, valops.c, z8k-tdep.c, config/a29k/tm-a29k.h, config/alpha/tm-alpha.h, config/gould/tm-pn.h, config/h8300/tm-h8300.h, config/h8500/tm-h8500.h, config/mips/tm-mips.h, config/ns32k/tm-merlin.h, config/ns32k/tm-umax.h, config/pyr/tm-pyr.h, config/sparc/tm-sparc.h): Replace FRAME with struct frame_info * everywhere, replace FRAME_ADDR with CORE_ADDR, rename variables consistently (using `frame' or `fi'), remove calls to get_frame_info and FRAME_INFO_ID, remove comments about FRAME and FRAME_ADDR cruftiness.
1994-10-08 The point of these changes is to avoid reading the frame pointerJim Kingdon1-2/+0
and stack pointer during stepping, to speed things up. A. Changes to not select a frame until we need a selected frame: * blockframe.c (flush_cached_frames): Call select_frame (NULL, -1). * infrun.c (wait_for_inferior): Move call to select_frame back to normal_stop. This reverts a change of 13 Apr 94 (it says Jeff Law, but the change was my idea); the only reason for that change was so we could save and restore the selected frame in wait_for_inferior, and now that flush_cached frames clears the selected frame, that should work OK now. B. Changes to not create a current_frame until we need one: * blockframe.c (get_current_frame): If current_frame is NULL, try to create an innermost frame. * sparc-tdep.c (sparc_pop_frame), infcmd.c (run-stack_dummy), infrun.c (wait_for_inferior), thread.c (thread_switch), convex-tdep.c (set_thread_command), a29k-tdep.c (pop_frame), alpha-tdep.c (alpha_pop_frame), convex-xdep.c (core_file_command), h8300-tdep.c (h8300_pop_frame), h8500-tdep.c (h8300_pop_frame), hppa-tdep.c (hppa_pop_frame), i386-tdep.c (i386_pop_frame), i960-tdep.c (pop_frame), m68k-tdep.c (m68k_pop_frame), mips-tdep.c (mips_pop_frame), rs6000-tdep.c (push_dummy_frame, pop_dummy_frame, pop_frame), sh-tdep.c (pop_frame), config/arm/tm-arm.h (POP_FRAME), config/convex/tm-convex.h (POP_FRAME), config/gould/tm-pn.h (POP_FRAME), config/ns32k/tm-merlin.h (POP_FRAME), config/ns32k/tm-umax.h (POP_FRAME), config/tahoe/tm-tahoe.h (POP_FRAME), config/vax/tm-vax.h (POP_FRAME): Don't call create_new_frame. * corelow.c (core_open), altos-xdep.c (core_file_command), arm-xdep.c (core_file_command), gould-xdep.c (core_file_command), m3-nat.c (select_thread), sun386-nat.c (core_file_command), umax-xdep.c (core_file_command): Don't call create_new_frame; do call flush_cached_frames. * blockframe.c (reinit_frame_cache): Don't call create_new_frame or select_frame. C. Changes to get rid of stop_frame_address and instead only fetch the frame pointer when we need it. * breakpoint.c (bpstat_stop_status): Remove argument frame_address; use FRAME_FP (get_current_frame ()). * infrun.c (wait_for_inferior): Don't pass frame pointer to bpstat_stop_status. * infrun.c (wait_for_inferior): Use FRAME_FP (get_current_frame ()) instead of stop_frame_address. * infrun.c (save_inferior_status, restore_inferior_status), inferior.h (struct inferior_status): Don't save and restore stop_frame_address. * inferior.h, infcmd.c, thread.c (thread_switch), m3-nat.c (select_thread): Remove stop_frame_address and uses thereof. D. Same thing for the stack pointer. * infrun.c (wait_for_inferior): Remove stop_sp and replace uses thereof with read_sp (). E. Change to eliminate one nasty little spot where we were wanting to know the frame pointer from before the current step (idea from GDB 3.5, which saved my ass, because my other ideas of how to fix it were very baroque). * infrun.c: Remove prev_frame_address. * infrun.c (wait_for_inferior, step_over_function): Use step_frame_address instead of prev_frame_address. F. Same basic idea for the stack pointer. * inferior.h, infcmd.c: New variable step_sp. * infcmd.c (step_1, until_next_command): Set it. * infrun.c: Remove prev_sp and replace uses by step_sp. * infrun.c (wait_for_inferior): If we get out of the step range, then set step_sp to the current stack pointer before we start going again.

1993-11-01Change the stream argument to _filtered to GDB_FILE *.Thomas Lord1-1/+1
Change all references to stdout/stderr to gdb_stdout/gdb_stderr. Replace all calls to stdio output functions with calls to corresponding _unfiltered functions (`fprintf_unfiltered') Replaced calls to fopen for output to gdb_fopen. Added sufficient goo to utils.c and defs.h to make the above work. The net effect is that stdio output functions are only directly used in utils.c. Elsewhere, the _unfiltered and _filtered functions and GDB_FILE type are used. In the near future, GDB_FILE will stop being equivalant to FILE. The semantics of some commands has changed in a very subtle way: called in the right context, they may cause new occurences of prompt_for_continue() behavior. The testsuite doesn't notice anything like this, though. Please respect this change by not reintroducing stdio output dependencies in the main body of gdb code. All output from commands should go to a GDB_FILE. Target-specific code can still use stdio directly to communicate with targets.
1993-10-22 * Makefile.in (init.c): Generate using the source, not munch. ThisJim Kingdon1-3/+0
cleans up all kinds of hassles (which nm to use in munch, etc). The new formatting conventions (mostly already followed) are that the name of the _initialize_* routines must start in column zero, and must not be inside #if. * munch: Removed. * Makefile.in: Remove references to munch. * serial.c, remote.c, infptrace.c, maint.c, convex-tdep.c, alpha-tdep.c, hp300ux-nat.c, hppab-nat.c, osfsolib.c, remote-es.c, procfs.c, remote-udi.c, ser-go32.c, ultra3-xdep.c, sh-tdep.c, i960-tdep.c, hppa-tdep.c, h8500-tdep.c, dpx2-nat.c, delta68-nat.c, z8k-tdep.c: Make sure the above conventions are followed. Make sure they are all declared as returning void. Clean up miscellaneous comments and such.
1993-10-11 * alpha-tdep.c (init_extra_frame_info): Remove kludge for gcc,Peter Schauer1-25/+5

Now that we have the bp_call_dummy breakpoint the call dummy code is no longer needed. PUSH_DUMMY_FRAME, PUSH_ARGUMENTS and FIX_CALL_DUMMY can be used to set up everything for the dummy. The breakpoint for the dummy is set at the entry point and thats it. * blockframe.c (inside_entry_file, inside_entry_func): Do not stop backtraces if pc is in the call dummy at the entry point. * infcmd.c (run_stack_dummy): Handle AT_ENTRY_POINT case.
