915 genRightShift): fixed bug with non-constant bit shift stored to
916 a volatile result (SF Open Discussion forum thread #1616749).
917 Single byte case is not yet optimized.

2820 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2822 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2823 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2825 One basic decision: e.g. src/clean.mk includes further files. In order
2826 to make this work there are two solutions:
2827 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2828 run configure on them. This way they can use
2829 'include $(srcdir)/port-clean.mk'
2830 - always include clean.mk by the Makefile at the same level. To avoid
2831 that `make clean` tries to include and build Makefile.dep the
2832 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2833 implemented, because now even `make uninstall` doesn't create
2834 Makefile.in. clean.mk could be eliminated by pasting it in
2837 * debugger/mcs51/Makefile.in: build own objects from library sources
2838 (SLIB, SDCC) in current directory
2840 * configure, configure.in: renamed --disable-device-lib-build in
2841 --disable-device-lib; added --enable-doc, the required tools are
2842 searched by configure; added result message; the toolchain for the
2843 belonging ports are now only built, if the port is enabled.
2845 * support/regression/*: all output is written in directory gen, because
2846 the fwk and ports directories don't livet in the build tree using vpath
2848 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2849 --disable-device-lib, added --enable-doc, added section VPATH
2851 * sim/ucsim/configure.in,
2852 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2853 z80 are enabled by default
2855 2006-04-24 Raphael Neider <rneider AT web.de>
2857 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2858 to config word, "pic14_"-prefixed some extern functions
2859 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2860 config word has been found
2861 * src/pic/device.h: added prototypes
2862 * src/pic/pcode.c: added "pic14_"-prefix where needed
2863 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2865 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
2867 (pic14emitRegularMap): ignore config words,
2868 (pic14createInterruptVect): moved generating __config directives away

2871 2006-04-24 Borut Razem <borut.razem AT siol.net>

2875 2006-04-24 Raphael Neider <rneider AT web.de>
2877 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
2878 registers that have not been assigned proper liveranges,
2879 fixes #1469504 and #1474602,
2880 (pCodeRegOptimizeRegUsage): fixed typo in comment
2882 2006-04-24 Borut Razem <borut.razem AT siol.net>
2884 * device/examples/main8051.c: deleted - it was removed from CVS

3103 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
3105 * src/mcs51/gen.c (genCall): fixed bug 1457608
3107 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3112 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
3114 * src/SDCCpeeph.c (operandsLiteral): new, added,

3126 implemented patch 1120823 Thanks to Willy De la Court (normal
3127 interrupts need an interrupt number now if they are made critical),
3128 and enabled nesting of critical functions though not for gbz80
3129 (genCritical, genEndCritical): added functions
3130 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3131 * src/z80/mappings.i: added "ei" to all mappings

3140 2006-03-16 Raphael Neider <rneider AT web.de>
3142 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
3143 the left operand is shorter than the result (c* = lit-c* + int),
3145 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3148 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3150 * src/.version: increased version number to 2.5.5
3151 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3152 linking is done manually in pic16 port's _linkEdit,
3153 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3154 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3155 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3156 allocate asmop as AOP_ACC,
3157 (aopForRemat): added parameter 'bool result' in function declaration,
3158 (pic16_aopGet): return AOP_ACC when accessing WREG,
3159 (pic16_popGetTempReg): minor modification,
3160 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
3161 'pic16_allocWithIdx',
3162 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
3163 calling function in absolute addresses,
3164 (genAssign): take into account AOP_ACC asmop,

3168 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
3170 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3171 call to allocReg, not by manually allocating a new one,
3172 (pic16_assignRegisters): now before going through the register
3173 allocating functions mark all registers as free. This eliminates some
3174 side effects resulting from peephole parser done earlier in the backbone
3176 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
3178 * src/SDCCicode.c (geniCodeLogic),

3197 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
3198 (aopForSym, aopOp): increment asmop.allocated if reused,
3199 (freeAsmop): decrement asmop.allocated and check for zero instead of
3201 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
3202 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
3203 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

3226 2006-03-06 Borut Razem <borut.razem AT siol.net>
3228 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3229 made the linker quiet
3231 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
3233 * src/pic16/gen.c (genPcall): fixed bug #1443644
3234 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3235 which dumps before the function entry point a data byte which represents
3236 the number of the local variables used by the specified function, added
3237 'xinst' for initial support for Extended Instruction Support,
3238 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3239 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3240 port->fun_prefix anymore (may change later),
3241 (genFunction, genEndFunction): do not store/restore local registers for
3242 _main (this should take care the --main-return command line option in
3244 (genOr): removed some legacy pic-port instructions,
3245 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3246 performing operations with SFR's causes data to be written more than
3247 once to each SFR. Perhaps SFRs should be handled in special cases...
3248 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3250 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3251 into account for stack starting position,
3252 (struct OPTIONS pic16_optionsTable): added command line argument
3253 --extended or -y for Extended Instruction Support,
3254 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3255 (deassignLRs): *** perhaps the most important change, old 'for' code
3256 (commented out for reference), didn't account for some registers which
3257 were left marked 'not free' after a pointer operation. The change
3258 reduces register usage a lot in some cases
3260 2006-03-04 Borut Razem <borut.razem AT siol.net>
3262 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

5539 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5540 reserved identifier "__data".
5542 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

5586 immedDom() returning wrong block; probably fixes bug #1160833)
5588 2005-03-20 Borut Razem <borut.razem AT siol.net>
5590 * support/scripts/inc2h.pl: WIN32 port

5594 * device/lib/makefile.in: added abs.c and labs.c
5596 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
5598 * device/include/stdint.h: added
5599 * device/lib/abs.c: added
5600 * device/lib/labs.c: added
5601 * device/include/stdlib.h: added abs() and labs() prototypes

5616 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5618 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5620 * device/lib/printf_large.c: removed inline assembly for portability and
5621 readability. Use printf_fast if speed or size are more important.
5622 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5623 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5625 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5627 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5628 prevent compiler warning
5630 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5632 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5633 moved to level 0 and declared as static. Also they are explicit
5634 placed in access bank. This was necessery because some times they
5635 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5636 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5637 optimizations. Currently only compare to unsigned char is implemented,
5638 * src/pic16/gen.c: added fReturnIdx array,
5639 * (struct resolvedIfx) is moved to gen.h and made public,
5640 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5641 * (aopForSym): added an optimization to directly store in stack of
5642 the operand of a SEND iCode,
5643 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5644 but as registers instead (AOP_REG) using the fReturnIdx array,
5645 * (pic16_freeAsmop): remove the freed register from the
5646 _G.sregsAlloc field,
5647 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5648 a compare of 'WREG',
5649 * (pic16_popGetTempRegCond): changed function prototype, now
5650 function takes also a bitVector argument v which holds the current
5651 set of registers that are allocated for stack access by aopForSym,
5652 registers allocated in aopForSym for accessing stack symbols are not
5653 any more part of the functions usedRegs field,
5654 * (genCall): some times aopOp is called for a stack variable to be
5655 send, aopForSym might perform the push, if this is true make sure
5656 that genCall doesn't push the variable twice by testing _G.resDirect,
5657 * (genFunction): changed testing for unspecified interrupt number
5658 from 256 to INTNO_UNSPEC,
5659 * modified selection scheme of frame pointer generation. Previously
5660 if function did use local registers a frame pointer was generated,
5661 now a frame pointer is generated only if function has arguments
5662 (that need PLUSW2 register access), or has stack arguments, or the
5663 compiler is not instructed to omit the frame pointer,
5664 * (genEndFunction): before restoring local registers that were saved
5665 in the function preamble, also restore the registers that *might*
5666 have been allocated for stack access,
5667 * (genRet): removed some old comments,
5668 * (genCmp, the active (RN's) version): added a call to the
5669 pic16_genCmp_special function to perform the compare with a more
5670 robust and optimized way,
5671 * (genInline): a feature has been added in inline code generation,
5672 which allows a wildcard variable substitution when writing inline
5673 assembly. Code is incomplete and experimental therefore undocumented,
5674 * (genCast): changed order of aopOp for result and right to allow
5675 aopForSym to directly load the result if possible,
5676 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5677 perform an optimized compare on some selected special occasions,
5678 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5679 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5680 generate an IVT any more,
5681 * src/pic16/main.c (pic16_optionsTable): added command line option
5683 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5684 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5686 * src/pic16/NOTES: Raphael Neider added in list of active developers
5687 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5688 jumptable_end to prevent bug #,
5689 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5690 inCond and outCond fields,
5691 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5692 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5693 turn off register spilling,
5694 * (packRegsForOneUse): synced with other ports' versions although it
5695 is not used currently,
5696 * (pic16_packRegisters): added an optimization while reading
5697 structure bitfields, some registers may be saved (malloc code is
5698 decreased by 80 bytes)
5700 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5702 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5703 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5704 this can be optimized more?
5706 2005-03-10 Raphael Neider <rneider AT web.de>
5708 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5709 genNearPointerGet): (hopefully) fixed access to bitfields via
5710 pointers (p->bitN = x; and x = p->bitN; failed)
5712 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

6344 Adding support for replacing ljmps with sjmps in jumptables
6345 generated for switch statements. For now you need to set the
6346 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6347 Now 4 algorithms for mcs51 jumptable generation are used:
6348 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6349 addresses loaded pc-relative for up to 112 cases and stack-pushing
6350 target addresses loaded with offset from dptr for up to 256 cases.

6380 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6382 * added libc directory. The current version of LibC contains string
6383 functions, ctype functions and macros and some functions of the
6384 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6385 be extensively tested in the future. Standard disclaimer here.
6386 Library is not automatically build yet. But one can build it by
6387 invoking 'make' inside the libc directory.
6388 * added ADC library under libio. Preliminary version yet.
6390 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

6397 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6398 * (pic16_storeForReturn): optimized return of 0,
6399 * (genCmp): experimental code for new genCmp which uses PIC18's
6400 special compare&skip instructions. Initial tests fail some times
6401 with variables grater than 1 byte in size, so new code is disabled,
6402 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6404 * (genCast): began a fix to optimize the casting of a bit to another
6405 bit, now assigning a bitfield to another bitfield will fail, sorry,
6406 * src/pic16/main.c: disabled the use of lr-support feature,
6407 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

6410 bits with offset (case PO_GPR_BIT),
6411 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6413 * (isBankInstruction): modified to return 0 for no banking instruction,
6414 and 1 for banking instruction,
6415 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,

9428 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9430 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9431 loaded with the linker search paths (-L arguments) and the libraries
9432 to be linked with the current source (-l arguments). Changes
9433 currently will affect only the pic16 port.
9434 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9435 include path the port specific paths and port specific libraries,
9436 * gplink command now contains the $3 argument,
9437 * src/pic16/device.h,
9438 * src/pic16/device.c,: structure PIC_device is made public and
9439 renamed to PIC16_device, the same for variable Pics which is renamed

9454 Documenting changes from previous commits.
9455 * configure.in (version 1.56),
9456 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9457 when generating output files to configure the pic16 library,
9458 but now I've commented it out, since gputils aren't installed in the
9459 SF compile farm, so library won't compile
9461 * device/lib/Makefile.in (version 1.56): initially I've added in
9462 target 'all' the prerequestive 'model-pic16' so it compiled the
9463 pic16 library, but now I've commented it out for the same reasons
9465 * added targets 'model-pic16' and 'objects-pic16' to compile the
9467 * added target 'port-specific-objects-pic16' to handle the
9468 generated libraries and copy them into the build/ directory
9469 * added target 'clean-intermediate-pic16' to clean intermediate
9470 files into pic16 directory
9471 * in target 'installdirs' added line to create directory pic16 in
9472 the installation path
9474 * device/include/Makefile.in (version 1.11): in target 'install'
9475 added lines to copy all header files to installation path,
9476 * in target 'installdirs' added line create directory for pic16
9477 headers in the installation path

9492 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9493 option so that it actually works. Made it specific to the z80, since
9494 the gbz80 doesn't have these kinds of I/O ports.
9496 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9498 * device/include/z180.h,

9527 weren't marked as being in the access bank,
9529 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9531 Added portion of GNU PIC Library under the directory
9532 device/include/pic16 and device/lib/pic16. These files
9533 contain the declarations of SFRs for the PIC18Fxx2 devices.
9534 The directory is initialized via configure from toplevel.
9536 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

9564 all over. Telling LaTeX to be less strict with word spacing
9565 to better keep the right margin. Changed some notes about
9566 maintainance of the ports in section 3.2.1 - is it OK like this?
9568 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9605 UPPER for immediate operands,
9606 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9608 * src/pic16/peeph.def: all peepholes with movff are commented out,
9609 because there is a problem in the pcode peep optimizer,
9610 * src/pic16/ralloc.c: the register allocator can now reuse local

9647 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9650 * src/z80/main.c: added missed needLinkerScript flags (more than
9651 one port structure defined in these file)
9652 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

9675 directive when no overlay data exist
9676 * (picglue): modified to emit uninitialized data segment
9677 according to udata_section_name

9682 arguments via -W option
9683 * src/pic16/main.c: added $l in _asmCmd, changed extension for
9684 object file from '.rel' to '.o' in port->linker structure,

9687 2004-01-07 Borut Razem <borut.razem AT siol.net>
9689 * support/scripts/sdcc.nsi: update PATH
9690 * support/scripts/sdcc.ico: craeted

9703 include information about variables allocated to the overlay
9706 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9708 * as/mcs51/lkmain.c: Help about -Y option

9718 LEFT_OP (left shift)
9720 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9722 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9723 (default behaviour).
9725 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9727 A python script to validate compiler diagnostic messages. It can be
9728 used to verify that sdcc complains about bad c source code and
9729 gives a good location of the error.
9730 * support/valdiag/Makefile,
9731 * support/valdiag/valdiag.py,
9732 * support/valdiag/tests/*
9734 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9736 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

9747 * src/common.h: added ifndef/define/endif macros
9748 around the header file.
9749 Bug reported from Jesus Calvino-Fraga
9751 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9753 * sdcc.spec: updated
9754 * device/include/Makefile.in: don't install CVS directories
9755 * device/lib/Makefile.in: added removal of CVS directories after install
9756 * doc/Makefile: fixed install, added local_icons
9757 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9758 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9759 * src/ds390/gen.c (genRightShift): fixed bug #870788
9760 * src/SDCCast.c (decorateType): fixed bug #870781
9762 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9764 PIC16 port related changes:
9765 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9766 added variable stackPos,
9768 * gen.c: genCall, assignResultValue: added support for
9769 pushing/retrieving function parameters to/from stack,
9770 genFunction,genEndFunction: setup stack frame for the
9772 genAddrOf: will be changed according to bug 863624
9774 * added files genutils.c and genutils.h which contain gen*
9775 debugged and optimised functions extracted from gen.c
9777 * glue.c: added variable 'externs' which holds extern symbols,
9778 pic16emitRegularMap: is modified to properly handle relocatable
9779 symbols under the new scheme,
9780 pic16createInterruptVect: is modified
9781 pic16printPublics: is modified to emit 'global' assembler directives,
9782 added pic16_printExterns to print extern symbols,
9783 pic16glue: initializes stack/frame pointer in the beginning of
9784 the assembly output. Temporary hack, will be corrected later,
9785 because gplink yet does not support stack and SDCC does not
9786 yet support a type of crt0.o object to create the final binary.
9788 * Removed many lines that contain 8051 legacy code.
9789 * The code is finally placed under a 'code' directive.
9790 * Added port specific options.
9792 * _process_pragma: simplified since now we do not need *special*
9793 include file to define SFR registers. But a separate header
9794 will be needed. This will be developed later.
9795 * _pic16_parseOptions: added, parses port specific options:
9796 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9797 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9798 --preplace-udata-with=
9800 * _pic16_setDefaultOptions: modified to initialize section names,
9801 but hack is temporarly out of order since it needs improvement.
9802 * _pic16_genAssemblerPreamble: configuration words are emitted by
9803 their address instead of their name. This part is incomplete and
9804 supports only the 18Fxx2 devices. Other devices will emit an error
9805 during assembly since they do not contain the same set of config
9807 * _pic16_genIVT: is modified,
9809 * pcode.c: added definitions for some hardware registers that are needed
9811 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9812 All PCI entries are updated. Now LFSR is supported.
9813 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9814 * added pic16_newpCodeOpLit2 to support instructions with
9815 two literal arguments
9816 * pic16_pCode2str: corrected code that emits assembler instructions
9817 with two literal operands and those that have an access bit modifier
9818 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9819 this fixes a bug which caused some labels to be lost, when an
9820 assembler directive was added, i.e. banksel,
9821 * pic16_FixRegisterBanking: improved logic that causes the insertion
9823 * InlineFunction: functions that are called once, are not any more
9824 inlined. This can be a port option in the future,
9826 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9828 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9829 hold the corresponding uninitialized symbols,
9830 * pic16_allocProcessorRegister: registers have explicit marked the
9832 * pic16_allocInternalRegister: registers are explicit marked as
9834 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9835 processing list, so bit registers were lost,
9838 * ralloc.h: added field 'accessBank' and original symbol operand
9839 in register definition,
9840 * removed the field isMapped from register definition,
9842 ** Several functions have been removed from various sources:
9843 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9844 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9845 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9846 pic16_assignRelocatableRegisters
9848 ** others have been introduced:
9849 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9850 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9852 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9854 * support/scripts/inc2h.pl: changed definition of BIT_AT
9855 to emit 'sbit at' instead of 'bit at'. This was a request.
9857 PIC16 port related preliminary changes:
9858 * gen.c: prefixed function popRegFromString with
9859 pic16_ and all references to it corrected
9860 * pcode.c: all pic16_pc_* hardware registers prefixed
9861 with underscore (_),
9862 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9863 * ralloc.c: newReg(): when register is REG_SFR then
9864 set address to rIdx,
9865 pic16_allocProcessorRegister(): marks register wasUsed=0
9866 pic16_writeUsedRegs(): added a call to assign processor
9867 registers via pic16_assignFixedRegisters
9869 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9871 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9872 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9873 variables in unused register banks. Also the SSEG is placed
9874 wherever there is enough space for it, and IDATA can be anywhere
9875 in internal RAM. For now compile using -Wl-Y[stack_size].
9876 The mem file is different for this option as well, since it
9877 makes no sense of talking about DSEG lenght.
9879 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9881 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9882 in certain cases, e.g. when ROM assignment, patch provided
9883 from Albert den Haan.
9885 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10027 SDCC_NOGENRAMCLEAR to disable this.
10028 * src/mcs51/peephole.def,
10029 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
10030 (allows non-interrupt and interrupt code to safely compete for a resource
10031 without the non-interrupt code having to disable interrupts)

10128 it breaks with bitfields, extern declarations, and gcse analysis.
10129 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10130 could be assigned through a pointer, so don't complain.

10906 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10908 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10909 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10910 type for bits was changed. It resulted in bit variables becoming
10911 global, which is not permitted in PIC 14 assembly output.
10913 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10915 * doc/sdccman.lyx: various additions and updates. Rearranged sections

10926 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10928 A few small changes that speed up the peephole optimizer.
10932 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10934 Try to make the peephole optimizer smarter by maintaining
10935 an association between the assembly source code and the
10936 iCodes that originated them. Put this information to use
10937 with a new peephole rule condition "notVolatile" so that
10938 the rules can be aggressive yet still safe.
10943 * src/mcs51/peeph.def
10945 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10949 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10950 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10951 if the left or right operand symbols have the accuse flag set.
10953 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10955 Changed the type of the result of the ! (NOT) operator to char;
10956 previously it returned the same type as the source. This allows
10957 us to eliminate all the genFloatNot functions (all of its target
10958 implementations were very buggy) since !float can use the same
10961 * src/SDCCicode.c (ast2iCode): ! returns char

10970 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10971 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10972 during interrupts. Ensure WSAVE is located at a shared bank address.
10973 2. Fixed page selection in some places
10974 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10975 the registers name strings.
10976 4. Fixed "signed / unsigned compare" compiler warnings.
10977 5. The PIC port manages its own allocation of the general purpose
10978 registers, but makes no attempt to reuse them. As a result when
10979 compiling it soon runs out of general purpose registers. Some
10980 additional code was added to the files pcode.c and device.c to walk
10981 through the function call tree and rename the registers so that they
10991 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10992 genPlus() & genMinus() when the result is the same as left or right

10998 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11000 Made bitfield a distinct type from bit so that bitfields
11001 convert as per ANSI C and bits retain their traditional
11002 boolean style behaviour. Implemented bitfield support in
11010 * src/ds390/gen.c: bit v bitfield split
11011 * src/z80/gen.c: New support for bitfields
11012 * support/regression/tests/bitfields.c: reenabled z80,
11015 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11017 Rules 246.x, 247.x relate to bitfields, the others speed up
11018 access to xdata mapped I/O devices.
11020 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11022 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11024 Cleaned up genPackBits and genUnpackBits and added two helper
11025 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11026 for literal assignments in genPackBits (thanks to Frieder for
11032 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11034 Fixed bug #748310 (pointer to function type mishandled when the
11035 function name is omitted). Also fixed a SIGSEGV when a function
11036 attribute (reentrant, etc) is used on a non-function or on a
11037 function but misplaced before the parameter list.
11039 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed

11064 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11066 Made the constant following the "interrupt" keyword optional. If
11067 omitted, the function will not automatically be given an entry
11068 in the interrupt vector table (similar to #pragma NOIV, but
11069 less syntacticly kludgy). The interrupt number is also now
11070 range checked. Also fixed a bug in the high order bit example

11515 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
11516 is in parts still quite out of date, I did changes as far as I felt makes sense
11517 for a non-native english speaker.
11518 Please feel free to add to the manual or to correct my changes.
11519 * doc/Makefile: undid touching the date of intermediate tex files.
11521 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

11529 * device/lib/_mullong.c
11530 * device/lib/gbz80/mul.s
11531 * device/lib/gbz80/stubs.s
11532 * device/lib/z80/mul.s
11533 * device/lib/z80/stubs.s
11534 * src/SDCCsymt.c (initCSupport)
11536 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

11540 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
11541 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used

11546 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
11547 the regression tests I'm not brave enough to enable 245.b, 245.c
11548 * doc/sdccman.lyx: added latex preamble for hyperref package.
11549 Using pdflatex this will give you a hyperlinked pdf file with
11550 bookmarks. (prepend '%' before /usepackage if this breaks something)
11552 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

11590 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
11591 it can be defined with CFLAGS when running configure
11592 * src/SDCCmain.c: fixed compiling + linking with object files
11594 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

11599 * src/SDCCmain.c: linkOptions is changed to set *,
11600 added if/endif conditional macros to remove options help
11601 messages from optionsTable when a port is not configured, added
11602 support for the PIc16 port in the ports table, when executing
11603 the compiler with no port specified on command line, a default
11604 port is selected with the new macro DEFAULT_PORT which is
11605 defined in port.h, in setDefaultOptions() linkOptions is removed
11606 from initialization assignment, since now it is a set,
11607 parseCmdLine uses setParseWithComma for linkOptions, in
11608 linkEdit() linkOptions are accessed with new function indexSet()
11609 which returns the i'th item of a set variable. See SDCCset.c, in
11610 linkEdit() when calling buildCmdLine(), added linkOptions as
11611 last argument. Now users can pass arguments to gplink via the
11612 -Wl option, main() uses pic16glue() to glue up pic16 programs
11613 * src/SDCCpeeph.c: various changes to support pic16
11614 * src/SDCCset.c: added function void *indexSet(set *, int) to

11624 * src/pic16/glue.c: commented out some error producing lines
11625 * src/pic16/main.c: __config directives are commented out to stop
11626 gpasm complaining and test the linkage with gplink, _linkCmd and
11627 _asmCmd changed to be more gplink and gpasm friendly
11628 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11629 produced an error when parsed, peep rule 12 is added to utilize
11630 movff, but it is commented out since the pCode does not support
11631 yet a command with 2 address arguments
11633 2003-05-18 <johan AT balder>
11635 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12699 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12700 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12701 following files to include the previous two files: aslink.dsp,
12702 Makefile.aslink, Makefile.bcc, and Makefile.in.
12704 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12705 .adb instead of .cdb
12707 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12709 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12710 value from option --iram-size.
12712 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12714 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12717 2002-09-18 <wiml AT hhhh.org>
12719 * SDCClrange.h: exposed setFromRange() and setToRange()
12720 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12721 packRegsForAccUse() (bug 542397)
12722 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12723 multiple times and emitting the fetch operations more than once
12724 added aopGetUsesAcc() function to allow binary operators to
12725 fetch their operands in the correct order; made genMinus() emit
12726 compact code for X = LITERAL - Y
12728 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12729 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to

12732 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12733 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12736 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12737 Changes to aslink (All the changes are marked with 'JCF'):
12739 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12742 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12743 area BSEG. Also moves, if possible, the DATA area down into the internal
12744 ram so more space is available.
12746 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12749 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12750 not bytes. Function summary() which creates a memory usage summary
12751 file with extension .mem. Reports of overlaping stack and small stack
12752 size. If the space for the stack is less than 16 bytes aslink trows a
12755 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12756 the 8051. Option 'y' for memory summary output file.
12758 Changes to sdcc (All the changes are marked with 'JCF'):
12760 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12762 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12763 overlaying area for it (uses RegBankUsed[4]).
12765 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12766 bank zero as used by default. By default aslink locates the stack
12767 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12768 the creation of the .mem file. Delegates the allocation of data area
12769 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12770 the begining of the stack area to aslink.
12772 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12773 glue() in SDCCglue.c creates an area for it.
12775 2002-09-03 Borut Razem <borut.razem AT siol.net>
12776 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12777 sdcc/src/pic/glue.c:
12778 introduced atexit() handler for teporay files removal in case of
12779 errors, assertions, ...
12781 2002-08-29 Borut Razem <borut.razem AT siol.net>
12782 * sdcc/support/cpp2/auto-host_vc_in.h:
12783 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12784 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12785 Maybe there is a similar problem with BORLANDC? It should be checked!
12787 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12788 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12789 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12790 was not executed, and the compiler (cl) launched a warning:
12791 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12793 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12794 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

12797 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12799 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12800 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12801 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12802 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12803 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12804 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12805 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12806 - added Release configuration in VS projects
12807 - review of compiler an linker options
12808 - VC .exe files are generated in bin_vc directory, not to interfere
12809 with binaries generated from other projects (cygwin, mingw, bcc ...)
12811 * sdcc/src/yacc.dsp: added
12813 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12814 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12815 and insert the version number definitions from .version
12817 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12819 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12820 added - genarate auto-host.h using auto-host_vc_in.h as template
12823 removed from CVS, generated automatically
12825 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12826 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12828 2002-08-11 Borut Razem <borut.razem AT siol.net>
12829 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12831 2002-08-10 Borut Razem <borut.razem AT siol.net>
12832 * src/SDCCmain.c (main):
12833 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12834 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12835 The consequence was that some temporary files were not removed.
12838 unification of code in functions tempfilename() and tempfile():
12839 function tempnam() is defined in Visual Studio 6.0 and .NET
12841 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12843 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12844 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12845 - removed compiler command line option /WX: Treats all warnings as errors
12846 - update a list of source files, included into the project
12848 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12849 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12850 changed project type to Generic Project so that can be correcly converted to VS.NET project
12852 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12854 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12856 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12858 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12859 added return 0 statements after assert() to make compiler happy
12861 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12862 added newline in the def file to keep MSC compiler satisfied
12864 * sdcc/src/z80/gen.c:
12865 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12866 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12867 - solved MSC error in function aopDump()
12869 * sdcc_vc.h: define PREFIX as "\\sdcc"
12871 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

13044 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13046 * sdcc/src/SDCCloop.c:
13047 Previous fix was not good. basic blocks that have "break" or "return" are
13048 not really partof a loop , but live ranges used in these blocks should
13049 be live thru the entire loop, so set partOfLoop but don't add them to
13052 2002-02-21 <johan AT FRIJA>
13054 * src/SDCCcse.c: fixed bug #514308
13056 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
