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 * 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 * 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 * Makefile.in (end.h): Use explicit ./ when running end. Sun May 19 21:05:31 1996 Rob Savoye * 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.
