Raw Blame History

Tue Dec 3 11:54:37 1996 Rob Savoye <rob@chinadoll.cygnus.com>
* configure.in: Look for libtermcap.a.
* Makefile.in: Only link in -ltermcap if it exists.
* erc32.c: Update to version 2.6a. Fix uart handling.
* exec.c: Update to version 2.6a. Add sparclite support.
* float.c: Update to version 2.6a. Convert comments to
preprocessor warnings. Add __setfpucw() for i385 hosts so floating
point exceptions work on win32.
* func.c: Update to version 2.6a. Fix uart handling, add support
for user error traps.
* help.c: Update to version 2.6a. Add help note on user error
traps.
* interf.c: Update to version 2.6a. Fix uart handling, and add
sparclite support.
* examples/gccx: Use sparclite cross compiler, not native gcc.
* examples/srt0.S: Use "mov" rather than "wr" for manipulating
the psr register.
Mon Nov 25 08:28:10 1996 Fred Fish <fnf@cygnus.com>
* Makefile.in (run.o): Remove this rule, it hides the one in
../common/Make-common.in that correctly references the source
in the sibling ../common directory.
Wed Nov 20 01:30:12 1996 Doug Evans <dje@canuck.cygnus.com>
* Makefile.in: Delete stuff moved to ../common/Make-common.in.
(SIM_{OBJS,EXTRA_LIBS,EXTRA_LIBDEPS,EXTRA_ALL,EXTRA_INSTALL}): Define.
(SIM_{EXTRA_CLEAN,EXTRA_CFLAGS}): Define.
* configure.in: Simplify using macros in ../common/aclocal.m4.
Call AC_CHECK_HEADERS(stdlib.h).
* configure: Regenerated.
* config.in: New file.
* func.c (sim_set_callbacks): Delete, moved to
* interf.c (sim_set_callbacks): here.
(sim_callback): New global.
Rewrite all calls to printf_filtered to go through callback.
(sim_size,sim_trace): New functions.
(sim_{insert,remove}_breakpoint): #if 0 out.
* sis.c: #include "config.h". #include <stdlib.h> if present.
(main): Coerce fprintf arg to INIT_DISASSEMBLE_INFO to fprintf_ftype.
* sis.h: #include "callback.h".
* run.c: Deleted, using one in ../common now.
Thu Oct 3 16:12:03 1996 Jason Molenda (crash@godzilla.cygnus.co.jp)
* Makefile.in (clean): Move config.log to distclean.
Wed Oct 2 16:57:57 1996 Jason Molenda (crash@godzilla.cygnus.co.jp)
* Makefile.in (clean): Also remove config.log.
Sat Sep 14 00:00:46 1996 Ian Lance Taylor <ian@cygnus.com>
* Makefile.in (CC_FOR_BUILD): New variable.
(AR, AR_FLAGS, BISON, MAKEINFO): Remove duplicate variables.
(RANLIB, CC): Likewise.
(end): Use $(CC_FOR_BUILD), not $(CC).
* configure.in: Set CC_FOR_BUILD.
* configure: Rebuild.
Sun Sep 8 14:04:37 1996 Stu Grossman (grossman@critters.cygnus.com)
* erc32.c (port_init): Disable this for __GO32__ (got no pty's
there either...).
Mon Aug 12 17:04:58 1996 Stu Grossman (grossman@critters.cygnus.com)
* erc32.c: Don't include sys/ioctl.h or sys/file.h. They aren't
necessary.
* (port_init): Don't even *try* to open pty's under _WIN32.
* Use SIM_ADDR, not caddr_t for declaring vars that hold addresses.
* float.c: Get rid of #warning. Makes Microsoft C barf.
* interf.c (sim_open): Cast fprintf to (fprintf_ftype) to fix
compiler warning.
* (sim_load sim_create_inferior sim_read): Use prototypes only in
decls, not defs.
* Get rid of enum sim_stop. It's defined in remote-sim.h.
* (sim_stop_reason): Define SIGTRAP if _WIN32.
* sis.h: Include ansidecl.h and remote-sim.h.
Wed Jul 3 16:05:23 1996 Stu Grossman (grossman@critters.cygnus.com)
* erc32.c (mec_reset mec_read mec_write memory_read memory_write),
sis.h: Get rid of all uses of long long's.
* (close_port read_uart write_uart uarta_tx): Don't seg fault
when can't open pty's.
* exec.c: Add two new instructions: smul, and divscc.
* interf.c (flush_windows): New routine to flush the register
windows out to the stack just before returning to GDB. Makes
backtraces work much better.
Wed Jun 26 12:19:11 1996 Jason Molenda (crash@godzilla.cygnus.co.jp)
* Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir,
INSTALL_PROGRAM, INSTALL_DATA): Use autoconf-set values.
(docdir, oldincludedir): Removed.
* configure.in (AC_PREREQ): autoconf 2.5 or higher.
(AC_PROG_INSTALL): Added.
* configure: Rebuilt.
Mon Jun 24 14:19:07 1996 Ian Lance Taylor <ian@cygnus.com>
* configure.in: Call AC_PROG_CC before running configure.host.
* configure: Rebuild with autoconf 2.10.
Tue Jun 4 10:37:12 1996 Tom Tromey <tromey@csk3.cygnus.com>
* Makefile.in (install): Don't check to see if tooldir exists.
Make $(tooldir) and $(tooldir)/bin.
Mon Jun 3 12:33:38 1996 Ian Lance Taylor <ian@cygnus.com>
* Makefile.in (end.h): Use explicit ./ when running end.
Sun May 19 21:05:31 1996 Rob Savoye <rob@chinadoll.cygnus.com>
* func.c(bfd_load): Don't try to print the filename if the pfbd is
NULL.
* interf.c(sim_load): Pass the whole string, not just the first
byte.
Version 2.1 26-02-96
--------------------
* Fixed bug in "go" command.
version 2.0 05-02-96
--------------------
* Fixed bug in interrupt force register (erc32.c).
* Change file load function to use bfd_openr.
* SIS should now be endian independent.
version 1.8 24-11-95
--------------------
* Fixed FPU timing - some sequences of FPU instructions did not calculate
the resource dependencies right.
* Corrected STDFQ when qne = 0 (again!). The ftt is set to sequence_error
but no FPU trap is generated.
version 1.7.1 31-10-95
--------------------
* Corrected STDFQ when qne = 0. Now, a trap is immidiately generated but
the FPU stays in execute mode.
* Corrected JMPL and RETT timing (these instructions takes two cycles).
version 1.7 25-10-95
--------------------
* Interrupt during annuled instruction corrupted return address - fixed.
version 1.6.2 25-10-95
--------------------
* Added -DFAST_UART to Makefile
version 1.6.1 24-10-95
--------------------
* Fixed bug in STDFQ which caused bus error
version 1.6 02-10-95
--------------------
* Modified srt0.s to include code that initiates registers in IU and FPU
and initializes the data segment. The simulator 'load' command does not
longer initialize the data segment!
* Corrected MEC timer operation; scalers now divide the frequency by
(scaler_value + 1).
* MEC breakpoints are not checked during store operation
version 1.5 14-09-95
--------------------
* Fixed some bugs in the cycle counting for IU & FPU instructions.
* Fixed bug that allowed an annuled instruction to cause memory exception.
* The *ws parameter in mem.c should now contain the number of waitstates
required by the memory access (was total number of cycles).
* The supplied srt0.s now clears the BSS (thanks Joel).
version 1.4 22-08-95
--------------------
* Added a '-g' switch to enable/disable the GNU readline(), which cause
some problems on solaris 2.x machines.
* Enabled MEC watchpoint and breakpoint function to mem.c. Performance
may suffer a bit ...
NOTE: The UARTs are now connected to /dev/ttypc and /dev/ttypd.
version 1.3 26-07-95
--------------------
* Fixed bug in mulscc instruction (how could that ever have worked?)
* Fixed bug in UART B (flushed characters on UART A), thanks Paul.
version 1.2 13-07-95
--------------------
* Fixed bug in interrupt handling (wrong interrupt selected when more that
one interrupt pending)
* Fixed updating of condition codes during logical instructions (carry and
overflow were not reset)
* Fixed bug in WRTBR (tt field was wrongly over-written)
version 1.1 07-07-95
--------------------
* Fixed several bugs in the interrupt handler and callback routines.
