+ * src/pic/pcodepeep.c,
+ * src/pic/pcoderegs.c,
+ * src/pic/ralloc.c,
+ * src/pic/ralloc.h: applied patch from Slade Rich;
+ added support for multiple code pages and multiple RAM banks on the
+ PIC 14 port. The ASM files now no longer simply assume all the
+ code / RAM are in the same page / bank. This means the linker can
+ safely allocate code/RAM of separate ASM files to different pages/banks.
+ * doc/sdccman.lyx: added Slade's tips

+
+2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
+
+ * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
+ loaded with the linker search paths (-L arguments) and the libraries
+ to be linked with the current source (-l arguments). Changes
+ currently will affect only the pic16 port.
+ * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
+ include path the port specific paths and port specific libraries,
+ * gplink command now contains the $3 argument,
+ * src/pic16/device.h,
+ * src/pic16/device.c,: structure PIC_device is made public and
+ renamed to PIC16_device, the same for variable Pics which is renamed
+ to Pics16. Updated all references to them.

+
+2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
+
+ Documenting changes from previous commits.
+ * configure.in (version 1.56),
+ * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
+ when generating output files to configure the pic16 library,
+ but now I've commented it out, since gputils aren't installed in the
+ SF compile farm, so library won't compile
+
+ * device/lib/Makefile.in (version 1.56): initially I've added in
+ target 'all' the prerequestive 'model-pic16' so it compiled the
+ pic16 library, but now I've commented it out for the same reasons
+ above,
+ * added targets 'model-pic16' and 'objects-pic16' to compile the
+ library
+ * added target 'port-specific-objects-pic16' to handle the
+ generated libraries and copy them into the build/ directory
+ * added target 'clean-intermediate-pic16' to clean intermediate
+ files into pic16 directory
+ * in target 'installdirs' added line to create directory pic16 in
+ the installation path
+
+ * device/include/Makefile.in (version 1.11): in target 'install'
+ added lines to copy all header files to installation path,
+ * in target 'installdirs' added line create directory for pic16
+ headers in the installation path
+

+2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
+
+ * src/z80/main.c (_parseOptions): fixed the portmode= command line
+ option so that it actually works. Made it specific to the z80, since
+ the gbz80 doesn't have these kinds of I/O ports.
+
+2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
+
+ * device/include/z180.h,

+
+2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

+
+2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
+
+ Mainly changes to support compilation of the device libraries
+ * src/pic16/device.c: stack is allocated via symbol and not
+ via literal number. The symbol is placed in the corresponding
+ position of the data ram
+ * (pic16_dump_section): relocatable and absolute uninitialized
+ data are now emitted in sorted order to reduce section naming,
+ * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
+ weren't marked as being in the access bank,
+
+2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
+
+ Added portion of GNU PIC Library under the directory
+ device/include/pic16 and device/lib/pic16. These files
+ contain the declarations of SFRs for the PIC18Fxx2 devices.
+ The directory is initialized via configure from toplevel.
+

+ doc/sdccman.lyx: upper case pragmas are deprecated
+
+2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
+
+ * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
+ in simpler and even better code
+
+2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
+
+ * src/SDCCicode.c (operandOperation): fixed bug #874819
+ * src/SDCCast.c (decorateType): fixed
+ char foo (unsigned long ul) { return ul > 0; }
+
+2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
+
+ * doc/sdccman.lyx: Moved and added some sections, small changes
+ all over. Telling LaTeX to be less strict with word spacing
+ to better keep the right margin. Changed some notes about
+ maintainance of the ports in section 3.2.1 - is it OK like this?
+
+2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
