1981 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1983 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1984 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1986 One basic decision: e.g. src/clean.mk includes further files. In order
1987 to make this work there are two solutions:
1988 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1989 run configure on them. This way they can use
1990 'include $(srcdir)/port-clean.mk'
1991 - always include clean.mk by the Makefile at the same level. To avoid
1992 that `make clean` tries to include and build Makefile.dep the
1993 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1994 implemented, because now even `make uninstall` doesn't create
1995 Makefile.in. clean.mk could be eliminated by pasting it in
1998 * debugger/mcs51/Makefile.in: build own objects from library sources
1999 (SLIB, SDCC) in current directory
2001 * configure, configure.in: renamed --disable-device-lib-build in
2002 --disable-device-lib; added --enable-doc, the required tools are
2003 searched by configure; added result message; the toolchain for the
2004 belonging ports are now only built, if the port is enabled.
2006 * support/regression/*: all output is written in directory gen, because
2007 the fwk and ports directories don't livet in the build tree using vpath
2009 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2010 --disable-device-lib, added --enable-doc, added section VPATH
2012 * sim/ucsim/configure.in,
2013 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2014 z80 are enabled by default
2016 2006-04-24 Raphael Neider <rneider AT web.de>
2018 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2019 to config word, "pic14_"-prefixed some extern functions
2020 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2021 config word has been found
2022 * src/pic/device.h: added prototypes
2023 * src/pic/pcode.c: added "pic14_"-prefix where needed

2041 (pCodeRegOptimizeRegUsage): fixed typo in comment

2264 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
2266 * src/mcs51/gen.c (genCall): fixed bug 1457608
2268 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

2273 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
2275 * src/SDCCpeeph.c (operandsLiteral): new, added,

2287 implemented patch 1120823 Thanks to Willy De la Court (normal
2288 interrupts need an interrupt number now if they are made critical),
2289 and enabled nesting of critical functions though not for gbz80
2290 (genCritical, genEndCritical): added functions
2291 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2292 * src/z80/mappings.i: added "ei" to all mappings

2301 2006-03-16 Raphael Neider <rneider AT web.de>
2303 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
2304 the left operand is shorter than the result (c* = lit-c* + int),
2306 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2309 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2311 * src/.version: increased version number to 2.5.5
2312 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2313 linking is done manually in pic16 port's _linkEdit,
2314 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2315 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2316 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2317 allocate asmop as AOP_ACC,
2318 (aopForRemat): added parameter 'bool result' in function declaration,
2319 (pic16_aopGet): return AOP_ACC when accessing WREG,
2320 (pic16_popGetTempReg): minor modification,
2321 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2322 'pic16_allocWithIdx',

2324 calling function in absolute addresses,
2325 (genAssign): take into account AOP_ACC asmop,

2329 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2331 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2332 call to allocReg, not by manually allocating a new one,
2333 (pic16_assignRegisters): now before going through the register
2334 allocating functions mark all registers as free. This eliminates some
2335 side effects resulting from peephole parser done earlier in the backbone
2337 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
2339 * src/SDCCicode.c (geniCodeLogic),

2358 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
2359 (aopForSym, aopOp): increment asmop.allocated if reused,
2360 (freeAsmop): decrement asmop.allocated and check for zero instead of
2362 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2363 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
2364 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

2387 2006-03-06 Borut Razem <borut.razem AT siol.net>
2389 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2390 made the linker quiet
2392 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2394 * src/pic16/gen.c (genPcall): fixed bug #1443644
2395 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2396 which dumps before the function entry point a data byte which represents
2397 the number of the local variables used by the specified function, added
2398 'xinst' for initial support for Extended Instruction Support,
2399 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2400 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2401 port->fun_prefix anymore (may change later),
2402 (genFunction, genEndFunction): do not store/restore local registers for
2403 _main (this should take care the --main-return command line option in
2405 (genOr): removed some legacy pic-port instructions,
2406 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2407 performing operations with SFR's causes data to be written more than
2408 once to each SFR. Perhaps SFRs should be handled in special cases...
2409 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2411 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2412 into account for stack starting position,
2413 (struct OPTIONS pic16_optionsTable): added command line argument
2414 --extended or -y for Extended Instruction Support,
2415 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2416 (deassignLRs): *** perhaps the most important change, old 'for' code
2417 (commented out for reference), didn't account for some registers which
2418 were left marked 'not free' after a pointer operation. The change
2419 reduces register usage a lot in some cases
2421 2006-03-04 Borut Razem <borut.razem AT siol.net>
2423 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

4700 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4701 reserved identifier "__data".
4703 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

4747 immedDom() returning wrong block; probably fixes bug #1160833)
4749 2005-03-20 Borut Razem <borut.razem AT siol.net>
4751 * support/scripts/inc2h.pl: WIN32 port

4755 * device/lib/makefile.in: added abs.c and labs.c
4757 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4759 * device/include/stdint.h: added
4760 * device/lib/abs.c: added
4761 * device/lib/labs.c: added
4762 * device/include/stdlib.h: added abs() and labs() prototypes

4769 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4771 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed

4777 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4779 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4781 * device/lib/printf_large.c: removed inline assembly for portability and
4782 readability. Use printf_fast if speed or size are more important.
4783 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4784 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4786 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4788 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4789 prevent compiler warning
4791 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4793 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4794 moved to level 0 and declared as static. Also they are explicit
4795 placed in access bank. This was necessery because some times they
4796 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4797 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4798 optimizations. Currently only compare to unsigned char is implemented,
4799 * src/pic16/gen.c: added fReturnIdx array,
4800 * (struct resolvedIfx) is moved to gen.h and made public,
4801 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4802 * (aopForSym): added an optimization to directly store in stack of
4803 the operand of a SEND iCode,
4804 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4805 but as registers instead (AOP_REG) using the fReturnIdx array,
4806 * (pic16_freeAsmop): remove the freed register from the
4807 _G.sregsAlloc field,
4808 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4809 a compare of 'WREG',
4810 * (pic16_popGetTempRegCond): changed function prototype, now
4811 function takes also a bitVector argument v which holds the current
4812 set of registers that are allocated for stack access by aopForSym,
4813 registers allocated in aopForSym for accessing stack symbols are not
4814 any more part of the functions usedRegs field,
4815 * (genCall): some times aopOp is called for a stack variable to be
4816 send, aopForSym might perform the push, if this is true make sure
4817 that genCall doesn't push the variable twice by testing _G.resDirect,
4818 * (genFunction): changed testing for unspecified interrupt number
4819 from 256 to INTNO_UNSPEC,
4820 * modified selection scheme of frame pointer generation. Previously
4821 if function did use local registers a frame pointer was generated,
4822 now a frame pointer is generated only if function has arguments
4823 (that need PLUSW2 register access), or has stack arguments, or the
4824 compiler is not instructed to omit the frame pointer,
4825 * (genEndFunction): before restoring local registers that were saved
4826 in the function preamble, also restore the registers that *might*
4827 have been allocated for stack access,
4828 * (genRet): removed some old comments,
4829 * (genCmp, the active (RN's) version): added a call to the
4830 pic16_genCmp_special function to perform the compare with a more
4831 robust and optimized way,
4832 * (genInline): a feature has been added in inline code generation,
4833 which allows a wildcard variable substitution when writing inline
4834 assembly. Code is incomplete and experimental therefore undocumented,
4835 * (genCast): changed order of aopOp for result and right to allow
4836 aopForSym to directly load the result if possible,
4837 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4838 perform an optimized compare on some selected special occasions,
4839 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4840 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4841 generate an IVT any more,
4842 * src/pic16/main.c (pic16_optionsTable): added command line option
4844 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4845 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4847 * src/pic16/NOTES: Raphael Neider added in list of active developers
4848 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4849 jumptable_end to prevent bug #,
4850 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4851 inCond and outCond fields,
4852 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4853 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4854 turn off register spilling,
4855 * (packRegsForOneUse): synced with other ports' versions although it
4856 is not used currently,
4857 * (pic16_packRegisters): added an optimization while reading
4858 structure bitfields, some registers may be saved (malloc code is
4859 decreased by 80 bytes)
4861 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4863 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4864 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4865 this can be optimized more?
4867 2005-03-10 Raphael Neider <rneider AT web.de>
4869 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4870 genNearPointerGet): (hopefully) fixed access to bitfields via
4871 pointers (p->bitN = x; and x = p->bitN; failed)
4873 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5061 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5062 this might fix SIGSEGVs on MinGW...

5505 Adding support for replacing ljmps with sjmps in jumptables
5506 generated for switch statements. For now you need to set the
5507 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5508 Now 4 algorithms for mcs51 jumptable generation are used:
5509 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5510 addresses loaded pc-relative for up to 112 cases and stack-pushing
5511 target addresses loaded with offset from dptr for up to 256 cases.

5541 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5543 * added libc directory. The current version of LibC contains string
5544 functions, ctype functions and macros and some functions of the
5545 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5546 be extensively tested in the future. Standard disclaimer here.
5547 Library is not automatically build yet. But one can build it by
5548 invoking 'make' inside the libc directory.
5549 * added ADC library under libio. Preliminary version yet.

5558 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5559 * (pic16_storeForReturn): optimized return of 0,
5560 * (genCmp): experimental code for new genCmp which uses PIC18's
5561 special compare&skip instructions. Initial tests fail some times
5562 with variables grater than 1 byte in size, so new code is disabled,
5563 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5565 * (genCast): began a fix to optimize the casting of a bit to another
5566 bit, now assigning a bitfield to another bitfield will fail, sorry,
5567 * src/pic16/main.c: disabled the use of lr-support feature,
5568 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5571 bits with offset (case PO_GPR_BIT),
5572 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5574 * (isBankInstruction): modified to return 0 for no banking instruction,
5575 and 1 for banking instruction,
5576 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,

8589 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8591 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8592 loaded with the linker search paths (-L arguments) and the libraries
8593 to be linked with the current source (-l arguments). Changes
8594 currently will affect only the pic16 port.
8595 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8596 include path the port specific paths and port specific libraries,
8597 * gplink command now contains the $3 argument,
8598 * src/pic16/device.h,
8599 * src/pic16/device.c,: structure PIC_device is made public and
8600 renamed to PIC16_device, the same for variable Pics which is renamed

8615 Documenting changes from previous commits.
8616 * configure.in (version 1.56),
8617 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8618 when generating output files to configure the pic16 library,
8619 but now I've commented it out, since gputils aren't installed in the
8620 SF compile farm, so library won't compile
8622 * device/lib/Makefile.in (version 1.56): initially I've added in
8623 target 'all' the prerequestive 'model-pic16' so it compiled the
8624 pic16 library, but now I've commented it out for the same reasons
8626 * added targets 'model-pic16' and 'objects-pic16' to compile the
8628 * added target 'port-specific-objects-pic16' to handle the
8629 generated libraries and copy them into the build/ directory
8630 * added target 'clean-intermediate-pic16' to clean intermediate
8631 files into pic16 directory
8632 * in target 'installdirs' added line to create directory pic16 in
8633 the installation path
8635 * device/include/Makefile.in (version 1.11): in target 'install'
8636 added lines to copy all header files to installation path,
8637 * in target 'installdirs' added line create directory for pic16
8638 headers in the installation path

8653 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8654 option so that it actually works. Made it specific to the z80, since
8655 the gbz80 doesn't have these kinds of I/O ports.
8657 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8659 * device/include/z180.h,

8688 weren't marked as being in the access bank,
8690 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8692 Added portion of GNU PIC Library under the directory
8693 device/include/pic16 and device/lib/pic16. These files
8694 contain the declarations of SFRs for the PIC18Fxx2 devices.
8695 The directory is initialized via configure from toplevel.
8697 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

8725 all over. Telling LaTeX to be less strict with word spacing
8726 to better keep the right margin. Changed some notes about
8727 maintainance of the ports in section 3.2.1 - is it OK like this?
8729 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8769 * src/pic16/peeph.def: all peepholes with movff are commented out,
8770 because there is a problem in the pcode peep optimizer,
8771 * src/pic16/ralloc.c: the register allocator can now reuse local

8848 2004-01-07 Borut Razem <borut.razem AT siol.net>
8850 * support/scripts/sdcc.nsi: update PATH
8851 * support/scripts/sdcc.ico: craeted

8864 include information about variables allocated to the overlay
8867 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8869 * as/mcs51/lkmain.c: Help about -Y option

8881 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8883 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8884 (default behaviour).
8886 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8888 A python script to validate compiler diagnostic messages. It can be
8889 used to verify that sdcc complains about bad c source code and
8890 gives a good location of the error.
8891 * support/valdiag/Makefile,
8892 * support/valdiag/valdiag.py,
8893 * support/valdiag/tests/*
8895 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8908 * src/common.h: added ifndef/define/endif macros
8909 around the header file.
8910 Bug reported from Jesus Calvino-Fraga
8912 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8914 * sdcc.spec: updated
8915 * device/include/Makefile.in: don't install CVS directories
8916 * device/lib/Makefile.in: added removal of CVS directories after install
8917 * doc/Makefile: fixed install, added local_icons
8918 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8919 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8920 * src/ds390/gen.c (genRightShift): fixed bug #870788
8921 * src/SDCCast.c (decorateType): fixed bug #870781
8923 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8925 PIC16 port related changes:
8926 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8927 added variable stackPos,
8929 * gen.c: genCall, assignResultValue: added support for
8930 pushing/retrieving function parameters to/from stack,
8931 genFunction,genEndFunction: setup stack frame for the
8933 genAddrOf: will be changed according to bug 863624
8935 * added files genutils.c and genutils.h which contain gen*
8936 debugged and optimised functions extracted from gen.c
8938 * glue.c: added variable 'externs' which holds extern symbols,
8939 pic16emitRegularMap: is modified to properly handle relocatable
8940 symbols under the new scheme,
8941 pic16createInterruptVect: is modified
8942 pic16printPublics: is modified to emit 'global' assembler directives,
8943 added pic16_printExterns to print extern symbols,
8944 pic16glue: initializes stack/frame pointer in the beginning of
8945 the assembly output. Temporary hack, will be corrected later,
8946 because gplink yet does not support stack and SDCC does not
8947 yet support a type of crt0.o object to create the final binary.
8949 * Removed many lines that contain 8051 legacy code.
8950 * The code is finally placed under a 'code' directive.
8951 * Added port specific options.
8953 * _process_pragma: simplified since now we do not need *special*
8954 include file to define SFR registers. But a separate header
8955 will be needed. This will be developed later.
8956 * _pic16_parseOptions: added, parses port specific options:
8957 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8958 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8959 --preplace-udata-with=
8961 * _pic16_setDefaultOptions: modified to initialize section names,
8962 but hack is temporarly out of order since it needs improvement.
8963 * _pic16_genAssemblerPreamble: configuration words are emitted by
8964 their address instead of their name. This part is incomplete and
8965 supports only the 18Fxx2 devices. Other devices will emit an error
8966 during assembly since they do not contain the same set of config
8968 * _pic16_genIVT: is modified,
8970 * pcode.c: added definitions for some hardware registers that are needed
8972 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8973 All PCI entries are updated. Now LFSR is supported.
8974 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8975 * added pic16_newpCodeOpLit2 to support instructions with
8976 two literal arguments
8977 * pic16_pCode2str: corrected code that emits assembler instructions
8978 with two literal operands and those that have an access bit modifier
8979 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8980 this fixes a bug which caused some labels to be lost, when an
8981 assembler directive was added, i.e. banksel,
8982 * pic16_FixRegisterBanking: improved logic that causes the insertion
8984 * InlineFunction: functions that are called once, are not any more
8985 inlined. This can be a port option in the future,
8987 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8989 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8990 hold the corresponding uninitialized symbols,
8991 * pic16_allocProcessorRegister: registers have explicit marked the
8993 * pic16_allocInternalRegister: registers are explicit marked as
8995 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8996 processing list, so bit registers were lost,
8999 * ralloc.h: added field 'accessBank' and original symbol operand
9000 in register definition,
9001 * removed the field isMapped from register definition,
9003 ** Several functions have been removed from various sources:
9004 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9005 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9006 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9007 pic16_assignRelocatableRegisters
9009 ** others have been introduced:
9010 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9011 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9013 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9015 * support/scripts/inc2h.pl: changed definition of BIT_AT
9016 to emit 'sbit at' instead of 'bit at'. This was a request.
9018 PIC16 port related preliminary changes:
9019 * gen.c: prefixed function popRegFromString with
9020 pic16_ and all references to it corrected
9021 * pcode.c: all pic16_pc_* hardware registers prefixed
9022 with underscore (_),
9023 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9024 * ralloc.c: newReg(): when register is REG_SFR then
9025 set address to rIdx,
9026 pic16_allocProcessorRegister(): marks register wasUsed=0
9027 pic16_writeUsedRegs(): added a call to assign processor
9028 registers via pic16_assignFixedRegisters
9030 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9032 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9033 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9034 variables in unused register banks. Also the SSEG is placed
9035 wherever there is enough space for it, and IDATA can be anywhere
9036 in internal RAM. For now compile using -Wl-Y[stack_size].
9037 The mem file is different for this option as well, since it
9038 makes no sense of talking about DSEG lenght.
9040 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9042 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9043 in certain cases, e.g. when ROM assignment, patch provided
9044 from Albert den Haan.
9046 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9188 SDCC_NOGENRAMCLEAR to disable this.
9189 * src/mcs51/peephole.def,
9190 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
9191 (allows non-interrupt and interrupt code to safely compete for a resource
9192 without the non-interrupt code having to disable interrupts)
9194 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9196 * src/SDCCicode.c (geniCodeAdd),

9216 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9218 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165
9220 2003-12-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9289 it breaks with bitfields, extern declarations, and gcse analysis.
9290 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9291 could be assigned through a pointer, so don't complain.

9952 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9954 Fixed bug #621531 (const & volatile confusion in the type chain).
9955 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

10035 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10036 iCode properly now. Use getSize instead of nRegs since a & b
10037 aren't part of the nRegs tally.

10053 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10054 If they pop r0/r1 they must be called in the opposite order than aopOp().
10055 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10056 (resp. --stack-auto), prepared for --xstack

10069 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10070 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10071 type for bits was changed. It resulted in bit variables becoming
10072 global, which is not permitted in PIC 14 assembly output.
10074 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10076 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10078 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10080 Z80 and MCS51 linkers complaint if a public symbol is defined

10087 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10089 A few small changes that speed up the peephole optimizer.
10093 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10095 Try to make the peephole optimizer smarter by maintaining
10096 an association between the assembly source code and the
10097 iCodes that originated them. Put this information to use
10098 with a new peephole rule condition "notVolatile" so that
10099 the rules can be aggressive yet still safe.
10104 * src/mcs51/peeph.def
10106 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10110 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10111 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10112 if the left or right operand symbols have the accuse flag set.
10114 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10116 Changed the type of the result of the ! (NOT) operator to char;
10117 previously it returned the same type as the source. This allows
10118 us to eliminate all the genFloatNot functions (all of its target
10119 implementations were very buggy) since !float can use the same
10122 * src/SDCCicode.c (ast2iCode): ! returns char

10131 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10132 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10133 during interrupts. Ensure WSAVE is located at a shared bank address.
10134 2. Fixed page selection in some places
10135 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10136 the registers name strings.
10137 4. Fixed "signed / unsigned compare" compiler warnings.
10138 5. The PIC port manages its own allocation of the general purpose
10139 registers, but makes no attempt to reuse them. As a result when
10140 compiling it soon runs out of general purpose registers. Some
10141 additional code was added to the files pcode.c and device.c to walk
10142 through the function call tree and rename the registers so that they
10152 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10153 genPlus() & genMinus() when the result is the same as left or right

10159 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10161 Made bitfield a distinct type from bit so that bitfields
10162 convert as per ANSI C and bits retain their traditional
10163 boolean style behaviour. Implemented bitfield support in
10171 * src/ds390/gen.c: bit v bitfield split
10172 * src/z80/gen.c: New support for bitfields
10173 * support/regression/tests/bitfields.c: reenabled z80,
10176 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10178 Rules 246.x, 247.x relate to bitfields, the others speed up
10179 access to xdata mapped I/O devices.
10181 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10183 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10185 Cleaned up genPackBits and genUnpackBits and added two helper
10186 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10187 for literal assignments in genPackBits (thanks to Frieder for
10193 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10195 Fixed bug #748310 (pointer to function type mishandled when the
10196 function name is omitted). Also fixed a SIGSEGV when a function
10197 attribute (reentrant, etc) is used on a non-function or on a
10198 function but misplaced before the parameter list.

10227 Made the constant following the "interrupt" keyword optional. If
10228 omitted, the function will not automatically be given an entry
10229 in the interrupt vector table (similar to #pragma NOIV, but
10230 less syntacticly kludgy). The interrupt number is also now
10231 range checked. Also fixed a bug in the high order bit example

10761 added if/endif conditional macros to remove options help
10762 messages from optionsTable when a port is not configured, added
10763 support for the PIc16 port in the ports table, when executing
10764 the compiler with no port specified on command line, a default
10765 port is selected with the new macro DEFAULT_PORT which is
10766 defined in port.h, in setDefaultOptions() linkOptions is removed
10767 from initialization assignment, since now it is a set,
10768 parseCmdLine uses setParseWithComma for linkOptions, in
10769 linkEdit() linkOptions are accessed with new function indexSet()
10770 which returns the i'th item of a set variable. See SDCCset.c, in
10771 linkEdit() when calling buildCmdLine(), added linkOptions as
10772 last argument. Now users can pass arguments to gplink via the
10773 -Wl option, main() uses pic16glue() to glue up pic16 programs

10786 * src/pic16/main.c: __config directives are commented out to stop
10787 gpasm complaining and test the linkage with gplink, _linkCmd and
10788 _asmCmd changed to be more gplink and gpasm friendly
10789 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10790 produced an error when parsed, peep rule 12 is added to utilize
10791 movff, but it is commented out since the pCode does not support
10792 yet a command with 2 address arguments
10794 2003-05-18 <johan AT balder>
10796 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11857 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11859 * in /sdcc/as/mcs51/ changed these files in order to create an
11860 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11861 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11862 following files to include the previous two files: aslink.dsp,
11863 Makefile.aslink, Makefile.bcc, and Makefile.in.
11865 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11866 .adb instead of .cdb
11868 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11870 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11871 value from option --iram-size.
11873 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11875 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11878 2002-09-18 <wiml AT hhhh.org>
11880 * SDCClrange.h: exposed setFromRange() and setToRange()
11881 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11882 packRegsForAccUse() (bug 542397)
11883 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11884 multiple times and emitting the fetch operations more than once
11885 added aopGetUsesAcc() function to allow binary operators to
11886 fetch their operands in the correct order; made genMinus() emit
11887 compact code for X = LITERAL - Y
11889 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11890 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11891 sprintf() in line 1267.
11893 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11894 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11897 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11898 Changes to aslink (All the changes are marked with 'JCF'):
11900 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11903 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11904 area BSEG. Also moves, if possible, the DATA area down into the internal
11905 ram so more space is available.
11907 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11910 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11911 not bytes. Function summary() which creates a memory usage summary
11912 file with extension .mem. Reports of overlaping stack and small stack
11913 size. If the space for the stack is less than 16 bytes aslink trows a
11916 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11917 the 8051. Option 'y' for memory summary output file.
11919 Changes to sdcc (All the changes are marked with 'JCF'):
11921 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11923 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11924 overlaying area for it (uses RegBankUsed[4]).
11926 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11927 bank zero as used by default. By default aslink locates the stack
11928 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11929 the creation of the .mem file. Delegates the allocation of data area
11930 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11931 the begining of the stack area to aslink.
11933 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11934 glue() in SDCCglue.c creates an area for it.
11936 2002-09-03 Borut Razem <borut.razem AT siol.net>
11937 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11938 sdcc/src/pic/glue.c:
11939 introduced atexit() handler for teporay files removal in case of
11940 errors, assertions, ...
11942 2002-08-29 Borut Razem <borut.razem AT siol.net>
11943 * sdcc/support/cpp2/auto-host_vc_in.h:
11944 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11945 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11946 Maybe there is a similar problem with BORLANDC? It should be checked!
11948 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11949 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11950 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11951 was not executed, and the compiler (cl) launched a warning:
11952 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11954 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11955 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

11967 - added Release configuration in VS projects
11968 - review of compiler an linker options
11969 - VC .exe files are generated in bin_vc directory, not to interfere
11970 with binaries generated from other projects (cygwin, mingw, bcc ...)
11972 * sdcc/src/yacc.dsp: added
11974 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11975 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11976 and insert the version number definitions from .version
11978 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11980 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11981 added - genarate auto-host.h using auto-host_vc_in.h as template

11986 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11987 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11989 2002-08-11 Borut Razem <borut.razem AT siol.net>
11990 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11992 2002-08-10 Borut Razem <borut.razem AT siol.net>
11993 * src/SDCCmain.c (main):
11994 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11995 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11996 The consequence was that some temporary files were not removed.
11999 unification of code in functions tempfilename() and tempfile():
12000 function tempnam() is defined in Visual Studio 6.0 and .NET
12002 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12004 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12005 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12006 - removed compiler command line option /WX: Treats all warnings as errors
12007 - update a list of source files, included into the project
12009 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12010 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12011 changed project type to Generic Project so that can be correcly converted to VS.NET project
12013 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12015 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

12019 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12020 added return 0 statements after assert() to make compiler happy
12022 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12023 added newline in the def file to keep MSC compiler satisfied
12025 * sdcc/src/z80/gen.c:
12026 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12027 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12028 - solved MSC error in function aopDump()
12030 * sdcc_vc.h: define PREFIX as "\\sdcc"
12032 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

12207 * sdcc/src/SDCCloop.c:
12208 Previous fix was not good. basic blocks that have "break" or "return" are
12209 not really partof a loop , but live ranges used in these blocks should
