+Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
+
+	* gen-semantics.c: Make the my_index variable a macro MY_INDEX.
+
+	* ppc-instructions: Adjust so that references are to MY_INDEX and
+        not my_index.
+
+Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
+
+	* gen-idecode.c: Output the complete run_until_stop function
+        instead of just the code to handle a single instruction issue.
+	* : Have the generated idecode.c include inline.c (instead of psim.c).
+
+	* std-config.h: Change psim.c so that it isn't inlined (as this is
+        no longer needed).
+
+	* psim.c (run_until_stop): Delete the old run_until_stop function
+        instead calling the idecode_run and idecode_run_until_stop
+        functions that gen-idecode.c is now creating.
+
+Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
+
+	* dgen.c: Maintenance - update to use new features found in lf.c.
+
+	* filter_filename.c (filter_filename): Maintenance - make the
+        string constant.
+
+Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
+
+	* debug.c (TRACE, ITRACE, DTRACE): Have GCC instead of CPP
+        eliminate trace statements.
+
+	* debug.c: Change trace format so that it is consistent
+        (file:line-nr) with CC's error output.
+
+	* gen-itable.c (itable_c_insn): Add the source file name and
+        source line number to the instruction's informational entry.
+
+	* debug.c (ITRACE): Use the itable (and my_index) to get the
+        current instructions name and source line number.
+
+	* gen-semantics.c, gen-icache.c: Adjust generated ITRACE calls to
+        match new interface.
+
+	* emul_bugapi.c (emul_bugapi_instruction_call): Adjust
+        corresponding call to ITRACE so that it still matches.
+
+	* idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
+        of ITRACE.  The CPP line directives would have previously set the
+        line-nr and file name so ITRACE isn't needed.
+
+Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
+
+	* gen-idecode.c (print_jump_until_stop_body): New function and
+        idecode generation option.  Instead of generating and calling
+        separate functions containing the semantic and icache code
+        generate a single monolythic function and use goto's (and GCC's
+        indirect jump) to move between code blocks.
+
+	* Makefile.in: Add sim_jump flag to those passed to igen.
+
+	* configure.in: New option --enable-sim-jump (default disabled)
+
+	* ppc-instructions: Eliminate any uses of labels and goto's.
+        These result in duplicate declarations when a single flat function
+        is being create.
+
+	* ppc-opcode-jump: New file.  Set of opcode rules useful when
+        testing jumping idecodes.
+
+Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
+
+	* gen-idecode.c: Optionally include the semantic code for an
+        instruction in the function that is doing the decoding.
+
+	* igen.c: Add option (-C) to generate semantics in the instruction
+        decode functions.
+
+	* configure.in (--enable-sim-icache): Accept an option list such
+        as 1024,define.  Add a new choice to the list - semantic - which
+        will cause igen to generate instruction decode functions that
+        include the corresponding semantic code.
+
+Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
+
+	* configure.in: New option --enable-sim-line-nr (default enabled).
+        Enable/disable the inclusion of CPP line directives in the
+        generated files.  Such directives refer back to the source files
+        used when generating the simulator code.
+
+	* Makefile.in (sim_line_nr): Pass to igen.
+
+Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
+
+	* igen.c (main): Revamp the options so that more letters are
+        available.
+
+	* configure.in: Adjust to match igen's revamped options
+
+Sun Jul 21 21:18:05 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
+
+	* Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
+        that they use the same technique as igen (ie a dummy targets
+        tmp-pk and tmp-hw are created).
+
+Mon Jun 24 22:28:00 1996  Andrew Cagney  <cagney@kremvax.highland.com.au>
+
+	* Makefile.in (BUILD_CFLAGS): Include WARNING_CFLAGS.

+	* Makefile.in (filter.o): Adjust
+	* configure.in: Adjust filter flag so that default includes 32bit
+	and floating point.

+Wed Jun 26 12:50:33 1996  Michael Meissner  <meissner@tiktok.cygnus.com>
+
+	* configure.in: Check for whether the termios and termio
+	structures are really defined, and whether or not, they define the
+	c_line field.

+	* Makefile.in ({,TERMIO_}CFLAGS): Add TERMIO_CFLAGS options set by
