This partially - reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect - of those changes was accidental. - - * stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is - defined, make it an error to specify a single argument which is not - a frame number. - - * Makefile.in (version.c), main.c (print_gdb_version): Use - host_alias and target_alias, not host_canonical and - target_canonical, to print configuration. - -Wed Jan 26 10:57:21 1994 Jim Kingdon (kingdon@lioth.cygnus.com) - - * parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead - of builtin_type_long.

Deal with it. - - * paread.c (read_unwind_info): Just assign to objfile->obj_private, - not OBJ_UNWIND_INFO. Assigning to a cast is a GCC-ism which - the HP compiler in ANSI mode doesn't like. - - * main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it - based on USG, rather than defining HAVE_SIGSETMASK to an - expression containing defined. Having a macro used in #if expand - to an expression containing "defined" is undefined according to - ANSI, and the HP compiler in ANSI mode doesn't do what we wanted - it to. - -Mon Jan 24 20:51:29 1994 John Gilmore (gnu@cygnus.com) - - * sparc-nat.c (fetch_inferior_registers, store_inferior_registers): - Clean up the changes of 11 Jan, as recommended by Peter Schauer. - -Fri Jan 21 19:10:44 1994 Per Bothner (bothner@kalessin.cygnus.com) - - * ch-exp.y (match_string_literal): Allow a zero-length string. - * ch-lang.c (chill_printstr): Don't print zero-length string funny. - -Sat Jan 22 17:08:48 1994 Jim Kingdon (kingdon@lioth.cygnus.com) - - * i386aix-nat.c (i386_float_info): Reverse order of registers before - passing them to print_387_status. - (print_387_status): Don't subtract top from 7 before using it. - * i387-tdep.c: Remove comment about AIX wanting "top" subtracted - from 7; the above explains it. - -Sat Jan 22 20:25:11 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de) - - * mips-tdep.c (init_extra_frame_info): Use frame relative stack - pointer value when fixing up the frame at the start of a function. - -Sat Jan 22 12:29:13 1994 Stu Grossman (grossman at cygnus.com) - - * lynx-nat.c (fetch_core_registers): Load the I & L regs for the - Sparc from the stack. - -Sat Jan 22 08:30:42 1994 Jim Kingdon (kingdon@deneb.cygnus.com) - - * remote-mips.c (mips_initialize): Clear mips_initializing via - cleanup chain, not directly. - - * ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout - of -1 mean forever, like in the HAVE_SGTTY case.

This - * is most easily accomplished by a call to breakpoint(). Breakpoint() - * simulates a breakpoint by executing a trap #1. - * - * The external function exceptionHandler() is - * used to attach a specific handler to a specific 386 vector number. - * It should use the same privilege level it runs at. It should - * install it as an interrupt gate so that interrupts are masked - * while the handler runs. - * Also, need to assign exceptionHook and oldExceptionHook. - * - * Because gdb will sometimes write to the stack area to execute function - * calls, this program cannot rely on using the supervisor stack so it - * uses it's own stack area reserved in the int array remcomStack. - * - ************* - * - * The following gdb commands are supported: - * - * command function Return value - * - * g return the value of the CPU registers hex data or ENN - * G set the value of the CPU registers OK or ENN - * - * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN - * MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN - * - * c Resume at current address SNN ( signal NN) - * cAA..AA Continue at address AA..AA SNN - * - * s Step one instruction SNN - * sAA..AA Step one instruction from AA..AA SNN - * - * k kill - * - * ?

One, a - * call to set_debug_traps() is necessary in order to allow any breakpoints - * or error conditions to be properly intercepted and reported to gdb. - * Two, a breakpoint needs to be generated to begin communication. This - * is most easily accomplished by a call to breakpoint(). Breakpoint() - * simulates a breakpoint by executing a trap #1. The breakpoint instruction - * is hardwired to trap #1 because not to do so is a compatibility problem-- - * there either should be a standard breakpoint instruction, or the protocol - * should be extended to provide some means to communicate which breakpoint - * instruction is in use (or have the stub insert the breakpoint). - * - * Some explanation is probably necessary to explain how exceptions are - * handled. When an exception is encountered the 68000 pushes the current - * program counter and status register onto the supervisor stack and then - * transfers execution to a location specified in it's vector table. - * The handlers for the exception vectors are hardwired to jmp to an address - * given by the relation: (exception - 256) * 6. These are decending - * addresses starting from -6, -12, -18, ... By allowing 6 bytes for - * each entry, a jsr, jmp, bsr, ... can be used to enter the exception - * handler. Using a jsr to handle an exception has an added benefit of - * allowing a single handler to service several exceptions and use the - * return address as the key differentiation. The vector number can be - * computed from the return address by [ exception = (addr + 1530) / 6 ]. - * The sole purpose of the routine _catchException is to compute the - * exception number and push it on the stack in place of the return address. - * The external function exceptionHandler() is - * used to attach a specific handler to a specific m68k exception. - * For 68020 machines, the ability to have a return address around just - * so the vector can be determined is not necessary because the '020 pushes an - * extra word onto the stack containing the vector offset - * - * Because gdb will sometimes write to the stack area to execute function - * calls, this program cannot rely on using the supervisor stack so it - * uses it's own stack area reserved in the int array remcomStack. - * - ************* - * - * The following gdb commands are supported: - * - * command function Return value - * - * g return the value of the CPU registers hex data or ENN - * G set the value of the CPU registers OK or ENN - * - * mAA..AA,LLLL Read LLLL bytes at address AA..AA hex data or ENN - * MAA..AA,LLLL: Write LLLL bytes at address AA.AA OK or ENN - * - * c Resume at current address SNN ( signal NN) - * cAA..AA Continue at address AA..AA SNN - * - * s Step one instruction SNN - * sAA..AA Step one instruction from AA..AA SNN - * - * k kill - * - * ? What was the last sigval ? SNN (signal NN) - * - * All commands and responses are sent with a packet which includes a - * checksum. A packet consists of - * - * $<packet info>#<checksum>. - * - * where - * <packet info> :: <characters representing the command or response> - * <checksum> :: < two hex digits computed as modulo 256 sum of <packetinfo>> - * - * When a packet is received, it is first acknowledged with either '+' or '-'. - * '+' indicates a successful transfer. '-' indicates a failed transfer. - * - * Example: - * - * Host: Reply: - * $m0,10#2a +$00010203040506070809101112131415#42 - * - ****************************************************************************/ - -#include <stdio.h> -#include <string.h> -#include <setjmp.h> - -/************************************************************************ - * - * external low-level support routines - */ -typedef void (*ExceptionHook)(int); /* pointer to function with int parm */ -typedef void (*Function)(); /* pointer to a function */ - -extern putDebugChar(); /* write a single character */ -extern getDebugChar(); /* read and return a single char */ - -extern Function exceptionHandler(); /* assign an exception handler */ -extern ExceptionHook exceptionHook; /* hook variable for errors/exceptions */ - -/************************/ -/* FORWARD DECLARATIONS */ -/************************/ -static void -initializeRemcomErrorFrame (); - -/************************************************************************/ -/* BUFMAX defines the maximum number of characters in inbound/outbound buffers*/ -/* at least NUMREGBYTES*2 are needed for register packets */ -#define BUFMAX 400 - -static char initialized; /* boolean flag. != 0 means we've been initialized */ - -int remote_debug; -/* debug > 0 prints ill-formed commands in valid packets & checksum errors */ - -static const char hexchars[]="0123456789abcdef"; - -/* there are 180 bytes of registers on a 68020 w/68881 */ -/* many of the fpa registers are 12 byte (96 bit) registers */ -#define NUMREGBYTES 180 -enum regnames {D0,D1,D2,D3,D4,D5,D6,D7, - A0,A1,A2,A3,A4,A5,A6,A7, - PS,PC, - FP0,FP1,FP2,FP3,FP4,FP5,FP6,FP7, - FPCONTROL,FPSTATUS,FPIADDR - }; - - -/* We keep a whole frame cache here.

The documentation - indicates that this bit is 1 for a data packet, but the actual - board uses 1 for an acknowledgement. The value of the byte is - 0x40 + (ack ? 0x20 : 0) + (len >> 6) - (we always have 0 <= len < 1024). Acknowledgement packets do - not carry data, and must have a data length of 0. - - LEN1 This byte contains the lower six bits of the logical length of - the data section. The value is - 0x40 + (len & 0x3f) - - SEQ This byte contains the six bit sequence number of the packet. - The value is - 0x40 + seq - An acknowlegment packet contains the sequence number of the - packet being acknowledged plus 1 modulo 64. Data packets are - transmitted in sequence. There may only be one outstanding - unacknowledged data packet at a time. The sequence numbers - are independent in each direction. If an acknowledgement for - the previous packet is received (i.e., an acknowledgement with - the sequence number of the packet just sent) the packet just - sent should be retransmitted.
