+
+2004-01-14 Vangelis Rokas <vrokas@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

+
+ * 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@ivorytower.norman.ok.us>
+
+ * device/include/z180.h,

+
+2004-01-13 Vangelis Rokas <vrokas@otenet.gr>
+
+ Mainly changes to support compilation of the device libraries
+ * src/pic16/device.c: stack is allocated via symbol and not

+ 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@otenet.gr>
+
+ Added portion of GNU PIC Library under the directory
+ device/include/pic16 and device/lib/pic16. These files

+
+2004-01-06 Vangelis Rokas <vrokas@otenet.gr>

+
+2004-01-06 Vangelis Rokas <vrokas@otenet.gr>
+
+ PIC16 port related changes:
+ * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
+ added variable stackPos,
+
+ * gen.c: genCall, assignResultValue: added support for
+ pushing/retrieving function parameters to/from stack,
+ genFunction,genEndFunction: setup stack frame for the
+ generated function,
+ genAddrOf: will be changed according to bug 863624
+
+ * added files genutils.c and genutils.h which contain gen*
+ debugged and optimised functions extracted from gen.c
+
+ * glue.c: added variable 'externs' which holds extern symbols,
+ pic16emitRegularMap: is modified to properly handle relocatable
+ symbols under the new scheme,
+ pic16createInterruptVect: is modified
+ pic16printPublics: is modified to emit 'global' assembler directives,
+ added pic16_printExterns to print extern symbols,
+ pic16glue: initializes stack/frame pointer in the beginning of
+ the assembly output. Temporary hack, will be corrected later,
+ because gplink yet does not support stack and SDCC does not
+ yet support a type of crt0.o object to create the final binary.
+
+ * Removed many lines that contain 8051 legacy code.
+ * The code is finally placed under a 'code' directive.
+ * Added port specific options.
+
+ * _process_pragma: simplified since now we do not need *special*
+ include file to define SFR registers. But a separate header
+ will be needed. This will be developed later.
+ * _pic16_parseOptions: added, parses port specific options:
+ --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
+ --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
+ --preplace-udata-with=
+
+ * _pic16_setDefaultOptions: modified to initialize section names,
+ but hack is temporarly out of order since it needs improvement.
+ * _pic16_genAssemblerPreamble: configuration words are emitted by
+ their address instead of their name. This part is incomplete and
+ supports only the 18Fxx2 devices. Other devices will emit an error
+ during assembly since they do not contain the same set of config
+ registers
+ * _pic16_genIVT: is modified,
+
+ * pcode.c: added definitions for some hardware registers that are needed
+ for stack support
+ * added flag is2LitOp and variable pci_magic in pCodeInstruction.
+ All PCI entries are updated. Now LFSR is supported.
+ * Removed pic16_pciTRIS is mentioned by mdubuc in source
+ * added pic16_newpCodeOpLit2 to support instructions with
+ two literal arguments
+ * pic16_pCode2str: corrected code that emits assembler instructions
+ with two literal operands and those that have an access bit modifier
+ * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
+ this fixes a bug which caused some labels to be lost, when an
+ assembler directive was added, i.e. banksel,
+ * pic16_FixRegisterBanking: improved logic that causes the insertion
+ of bank switching,
+ * InlineFunction: functions that are called once, are not any more
+ inlined. This can be a port option in the future,
+
+ * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
+
+ * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
+ hold the corresponding uninitialized symbols,
+ * pic16_allocProcessorRegister: registers have explicit marked the
+ accessBank field,
+ * pic16_allocInternalRegister: registers are explicit marked as
+ not used,
+ * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
+ processing list, so bit registers were lost,
+ *
+
+ * ralloc.h: added field 'accessBank' and original symbol operand
+ in register definition,
+ * removed the field isMapped from register definition,
+
+ ** Several functions have been removed from various sources:
+ BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
+ pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
+ isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
+ pic16_assignRelocatableRegisters
+
+ ** others have been introduced:
+ pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
+ pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
+
+2004-01-05 Vangelis Rokas <vrokas@otenet.gr>
+
+ * support/scripts/inc2h.pl: changed definition of BIT_AT
+ to emit 'sbit at' instead of 'bit at'. This was a request.
+
+ PIC16 port related preliminary changes:
+ * gen.c: prefixed function popRegFromString with
+ pic16_ and all references to it corrected
+ * pcode.c: all pic16_pc_* hardware registers prefixed
+ with underscore (_),
+ pic16_popCopyGPR2Bit(): function sets register wasUsed=1
+ * ralloc.c: newReg(): when register is REG_SFR then
+ set address to rIdx,
+ pic16_allocProcessorRegister(): marks register wasUsed=0
+ pic16_writeUsedRegs(): added a call to assign processor
+ registers via pic16_assignFixedRegisters
+
+2004-01-04 Jesus Calvino-Fraga <jesusc@ece.ubc.ca>
+
+ * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
+ as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
+ variables in unused register banks. Also the SSEG is placed
+ wherever there is enough space for it, and IDATA can be anywhere
+ in internal RAM. For now compile using -Wl-Y[stack_size].
+ The mem file is different for this option as well, since it
+ makes no sense of talking about DSEG lenght.
+
+2004-01-02 Vangelis Rokas <vrokas@otenet.gr>
+
+ * src/SDCClrange.c: fixed bug 869095 that caused segfault
+ in certain cases, e.g. when ROM assignment, patch provided
+ from Albert den Haan.
+
+2004-01-01 Bernhard Held <bernhard@bernhardheld.de>

+ * src/SDCCloop.c (loopInvariants): Spill location of the
+ result operand should be recomputed if extracted from
+ a loop. Also, don't extract assignments of an iTemp
+ from a literal.
+ * src/SDCCast.c (isConformingBody): loop reversal should
+ not occur if the control variable is involved with a
+ relational operator.
