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.
