1996-05-26 Changes from: David Mosberger-Tang <davidm@azstarnet.com>Fred Fish4-35/+6
* 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>
1996-05-20 * config/sparc/sparclite.mt: Add the sparc simulator.Rob Savoye1-1/+3

1996-05-15 * coffread.c (coff_symtab_read): Handle C_LABEL symbols likeJeff Law1-0/+2
C_STAT symbols. * h8300-tdep.c (h8300_pop_frame): Reset $sp and $pc correctly. Flush cached frames just before exiting. * remote-sim.c (gdbsim_resume): Complain if the program isn't being run. * config/h8300/tm-h8300.h (BELIEVE_PCC_PROMOTION): Define. Fix some bugs exposed by the testsuite. HMSE.
1996-05-15 * procfs.c (procfs_thread_alive procfs_stop): Make static.Stu Grossman1-0/+5

config/sparc/nm-sun4sol2.h config/sparc/sun4sol2.mh config/sparc/tm-sun4sol2.h: Use autoconf to config Solaris thread and pthread support, since pre-2.5 systems don't come with libthread_db.so.1. * procfs.c (info_proc): Use int instead of id_t. Old versions of Irix don't see to define this.
1996-05-13 SH3-E support from Allan Tajii <atajii@hmsi.com>:Stan Shebs1-9/+10
* sh-tdep.c (sh_reg_names, sh3_reg_names): Add empty names for float registers. (sh3e_reg_names): New register name array. (sh_processor_type_table): Add sh3e processor type. * config/sh/tm-sh.h (REGISTER_VIRTUAL_TYPE): Fix test. (REGISTER_NAMES, NUM_REGS, NUM_REALREGS, etc): Adjust for full set of registers. * remote-e7000.c (want_sh3, want_sh3_nopc): New globals.

1996-05-06 * fork-child.c (fork_inferior), inferior.h: init_trace_fun nowStu Grossman3-1/+17
returns a possibly modified pid. * inftarg.c (ptrace_him): Now returns pid; * m3-nat.c (m3_trace_him): Now returns pid; * infcmd.c (run_command): Minor cleanup. * infrun.c (wait_for_inferior): Add another check for one_stepped near where we read the pc to avoid erroneously setting random_signal for multi-threaded support. * procfs.c: Add support for Solaris LWPs. Remove def of LOSING_POLL. Many cleanups... Several workarounds for Solaris lossage. System call entry and exit are now handled by dynamically registered handlers. * (syscallname): Don't barf when handed an unknown syscall number. * (info_proc_syscalls): Ditto. * sol-thread.c: New file. Implements Solaris thread support. * symfile.c (symbol_file_add): Add call to target_new_objfile to notify target-dependent code about new symbol tables. * (clear_symtab_users): Call target_new_objfile to notify it of the removal of all symbol tables. * target.c (push_target): Make sure that to_close is non-zero before calling it. * target.h (target_new_objfile): Provide default. * config/alpha/nm-osf2.h: Define LOSING_POLL because this version of OSF can't hack using poll with /proc. * config/sparc/nm-sun4sol2.h (target_new_objfile): Define to be sol-thread-new-objfile. * config/sparc/sun4sol2.mh: Add sol-thread.o to NATDEFFILES, and add libthread_db.so.1 to NAT_CLIBS. * config/sparc/tm-sun4sol2.h: Define PIDGET, TIDGET, and target_pid_to_str.
1996-04-30Add bieginning of Solaris/PowerPC supportMichael Meissner5-1/+135
1996-04-28 Support for bi-endian remote breakpoints.Stan Shebs1-1/+3
* remote.c (big_break_insn, little_break_insn): New globals. (break_insn): Remove. (remote_insert_breakpoint, remote_remove_breakpoint): Use own code if REMOTE_BREAKPOINT defined, otherwise call memory breakpoint functions. * config/sh/tm-sh.h (REMOTE_BREAKPOINT): Remove. (BIG_REMOTE_BREAKPOINT, LITTLE_REMOTE_BREAKPOINT): Define.
1996-04-17 * corelow.c (add_to_thread_list): Make sure reg_sect is non-nullStu Grossman1-2/+2
before de-referencing it. Prevents deref of NULL pointer if core file lacks .reg section. * defs.h: Rename floatformat_{to from}_long_double to floatformat_{to from}_doublest. Get rid of FLOATFORMAT_{TO FROM}... macros. * findvar.c (extract_floating store_floating): Change all refs to FLOATFORMAT_{FROM TO}... to floatformat_{from to}_doublest. * utils.c: Change floatformat_{to from}_long_double to floatformat_{to from}_doublest cuz the new routines will use whatever size (double or long double) is appropriate. * config/i960/tm-i960.h (REGISTER_CONVERT_TO_VIRTUAL REGISTER_CONVERT_TO_RAW): Change FLOATFORMAT... macros to floatformat... routine calls.
1996-04-13 * remote-nindy.c (nindy_open): Acquire more target state so thatStu Grossman2-4/+8
user can attach to a previously running program. * (nindy_fetch_registers nindy_store_registers): Get rid of fp conversion code. That's all handled in {extract store}_floating now. * utils.c (floatformat_to_double): Don't bias exponent when handling zero's, denorms or NaNs. * config/i960/tm-i960.h (REGISTER_CONVERT_TO_VIRTUAL REGISTER_CONVERT_TO_RAW): Change to using DOUBLST and FLOATFORMAT_TO/FROM_DOUBLEST macros. * config/i960/tm-nindy960.h: Undefine REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW, and REGISTER_CONVERTIBLE. These are no longer necessary now that all the magic happens in extract/store_floating.
1996-04-12 * config/nm-m3.h (ATTACH_NO_WAIT): Define.Fred Fish1-0/+3
1996-04-11 * dcache.c: Add prototypes. Make many functions static.Stu Grossman1-0/+2
* (dcache_peek dcache_fetch dcache_poke): Make dcache_fetch and dcache_poke call dcache_xfer_memory directly in order to fix problems with turning off dcache. dcache_peek is now unnecessary, so it goes away. * defs.h: Define new macros HOST_{FLOAT DOUBLE LONG_DOUBLE}_FORMAT and TARGET_{FLOAT DOUBLE LONG_DOUBLE}_FORMAT to specify a pointer to a struct floatformat. This allows for better handling of targets whose floating point formats differ from the host by more than just byte order. * (floatformat_to_long_double floatformat_from_long_double): Prototypes for new functions in utils.c. * (floatformat_to_doublest floatformat_from_doublest): Prototypes for pointers to floating point conversion functions. The actual function uses either double or long double if the host supports it. * findvar.c (floatformat_to_doublest floatformat_from_doublest): Initialize to point at correct function depending on HAVE_LONG_DOUBLE. * (extract_floating store_floating): Rewrite. Now, if host fp format is the same as the target, we just do a copy. Otherwise, we call floatformat_{to from}_doublest. * remote-nindy.c (nindy_xfer_inferior_memory): Change param `write' to `should_write'. * utils.c (floatformat_to_long_double floatformat_from_long_double): New routines that implement long double versions of functions in libiberty/floatformat.c. * config/i960/tm-i960.h (TARGET_LONG_DOUBLE_FORMAT): Define this for i960 extended real (80 bit) numbers. * nindy-share/nindy.c (ninMemGet ninMemPut): Return number of bytes actually read or written.
