2688 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2690 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2691 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2693 One basic decision: e.g. src/clean.mk includes further files. In order
2694 to make this work there are two solutions:
2695 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2696 run configure on them. This way they can use
2697 'include $(srcdir)/port-clean.mk'
2698 - always include clean.mk by the Makefile at the same level. To avoid
2699 that `make clean` tries to include and build Makefile.dep the
2700 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2701 implemented, because now even `make uninstall` doesn't create
2702 Makefile.in. clean.mk could be eliminated by pasting it in
2705 * debugger/mcs51/Makefile.in: build own objects from library sources
2706 (SLIB, SDCC) in current directory
2708 * configure, configure.in: renamed --disable-device-lib-build in
2709 --disable-device-lib; added --enable-doc, the required tools are
2710 searched by configure; added result message; the toolchain for the
2711 belonging ports are now only built, if the port is enabled.
2713 * support/regression/*: all output is written in directory gen, because
2714 the fwk and ports directories don't livet in the build tree using vpath
2716 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2717 --disable-device-lib, added --enable-doc, added section VPATH
2719 * sim/ucsim/configure.in,
2720 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2721 z80 are enabled by default
2723 2006-04-24 Raphael Neider <rneider AT web.de>
2725 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2726 to config word, "pic14_"-prefixed some extern functions
2727 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2728 config word has been found
2729 * src/pic/device.h: added prototypes
2730 * src/pic/pcode.c: added "pic14_"-prefix where needed
2731 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2733 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

3021 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3022 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3023 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3024 allocate asmop as AOP_ACC,
3025 (aopForRemat): added parameter 'bool result' in function declaration,
3026 (pic16_aopGet): return AOP_ACC when accessing WREG,
3027 (pic16_popGetTempReg): minor modification,
3028 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
3029 'pic16_allocWithIdx',
3030 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
3031 calling function in absolute addresses,
3032 (genAssign): take into account AOP_ACC asmop,
3033 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
3034 * src/pic16/pcoderegs.c: some debug functions and lines added,
3035 * src/pic16/ralloc.c (decodeRegType): added but commented out,
3036 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
3038 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3039 call to allocReg, not by manually allocating a new one,
3040 (pic16_assignRegisters): now before going through the register
3041 allocating functions mark all registers as free. This eliminates some
3042 side effects resulting from peephole parser done earlier in the backbone
3044 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3065 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
3066 (aopForSym, aopOp): increment asmop.allocated if reused,
3067 (freeAsmop): decrement asmop.allocated and check for zero instead of
3069 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
3070 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

3092 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
3094 2006-03-06 Borut Razem <borut.razem AT siol.net>
3096 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3097 made the linker quiet
3099 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
3101 * src/pic16/gen.c (genPcall): fixed bug #1443644
3102 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3103 which dumps before the function entry point a data byte which represents
3104 the number of the local variables used by the specified function, added
3105 'xinst' for initial support for Extended Instruction Support,
3106 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3107 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3108 port->fun_prefix anymore (may change later),
3109 (genFunction, genEndFunction): do not store/restore local registers for
3110 _main (this should take care the --main-return command line option in
3112 (genOr): removed some legacy pic-port instructions,
3113 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3114 performing operations with SFR's causes data to be written more than
3115 once to each SFR. Perhaps SFRs should be handled in special cases...
3116 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3118 * src/pic16/main.c (_process_pragma): stack bound checking did not take

3121 --extended or -y for Extended Instruction Support,
3122 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3123 (deassignLRs): *** perhaps the most important change, old 'for' code
3124 (commented out for reference), didn't account for some registers which
3125 were left marked 'not free' after a pointer operation. The change
3126 reduces register usage a lot in some cases

5484 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5486 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5488 * device/lib/printf_large.c: removed inline assembly for portability and
5489 readability. Use printf_fast if speed or size are more important.
5490 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5491 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5493 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5495 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5496 prevent compiler warning
5498 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5500 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5501 moved to level 0 and declared as static. Also they are explicit
5502 placed in access bank. This was necessery because some times they
5503 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5504 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5505 optimizations. Currently only compare to unsigned char is implemented,
5506 * src/pic16/gen.c: added fReturnIdx array,
5507 * (struct resolvedIfx) is moved to gen.h and made public,
5508 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5509 * (aopForSym): added an optimization to directly store in stack of
5510 the operand of a SEND iCode,
5511 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5512 but as registers instead (AOP_REG) using the fReturnIdx array,
5513 * (pic16_freeAsmop): remove the freed register from the
5514 _G.sregsAlloc field,
5515 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5516 a compare of 'WREG',
5517 * (pic16_popGetTempRegCond): changed function prototype, now
5518 function takes also a bitVector argument v which holds the current
5519 set of registers that are allocated for stack access by aopForSym,
5520 registers allocated in aopForSym for accessing stack symbols are not
5521 any more part of the functions usedRegs field,
5522 * (genCall): some times aopOp is called for a stack variable to be
5523 send, aopForSym might perform the push, if this is true make sure
5524 that genCall doesn't push the variable twice by testing _G.resDirect,
5525 * (genFunction): changed testing for unspecified interrupt number
5526 from 256 to INTNO_UNSPEC,
5527 * modified selection scheme of frame pointer generation. Previously
5528 if function did use local registers a frame pointer was generated,
5529 now a frame pointer is generated only if function has arguments
5530 (that need PLUSW2 register access), or has stack arguments, or the
5531 compiler is not instructed to omit the frame pointer,
5532 * (genEndFunction): before restoring local registers that were saved
5533 in the function preamble, also restore the registers that *might*
5534 have been allocated for stack access,
5535 * (genRet): removed some old comments,
5536 * (genCmp, the active (RN's) version): added a call to the
5537 pic16_genCmp_special function to perform the compare with a more
5538 robust and optimized way,
5539 * (genInline): a feature has been added in inline code generation,
5540 which allows a wildcard variable substitution when writing inline
5541 assembly. Code is incomplete and experimental therefore undocumented,
5542 * (genCast): changed order of aopOp for result and right to allow
5543 aopForSym to directly load the result if possible,
5544 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,

6212 Adding support for replacing ljmps with sjmps in jumptables
6213 generated for switch statements. For now you need to set the
6214 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6215 Now 4 algorithms for mcs51 jumptable generation are used:
6216 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6217 addresses loaded pc-relative for up to 112 cases and stack-pushing
6218 target addresses loaded with offset from dptr for up to 256 cases.

6248 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6250 * added libc directory. The current version of LibC contains string
6251 functions, ctype functions and macros and some functions of the
6252 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6253 be extensively tested in the future. Standard disclaimer here.
6254 Library is not automatically build yet. But one can build it by
6255 invoking 'make' inside the libc directory.

6266 * (pic16_storeForReturn): optimized return of 0,
6267 * (genCmp): experimental code for new genCmp which uses PIC18's
6268 special compare&skip instructions. Initial tests fail some times
6269 with variables grater than 1 byte in size, so new code is disabled,
6270 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6272 * (genCast): began a fix to optimize the casting of a bit to another
6273 bit, now assigning a bitfield to another bitfield will fail, sorry,

6282 and 1 for banking instruction,
6283 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6284 caused stop processing pCodes after a inline assembly block,
6285 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

6287 registers when it shouldn't,
6288 * src/pic16/ralloc.c (allocReg): add preliminary support for
6289 supporting a limited set of temporary registers,
6291 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6297 (genFunction): optimize RECEIVE iCodes in reentrant functions
6299 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9299 loaded with the linker search paths (-L arguments) and the libraries
9300 to be linked with the current source (-l arguments). Changes
9301 currently will affect only the pic16 port.
9302 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9303 include path the port specific paths and port specific libraries,
9304 * gplink command now contains the $3 argument,
9305 * src/pic16/device.h,
9306 * src/pic16/device.c,: structure PIC_device is made public and
9307 renamed to PIC16_device, the same for variable Pics which is renamed

9322 Documenting changes from previous commits.
9323 * configure.in (version 1.56),
9324 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9325 when generating output files to configure the pic16 library,
9326 but now I've commented it out, since gputils aren't installed in the
9327 SF compile farm, so library won't compile
9329 * device/lib/Makefile.in (version 1.56): initially I've added in
9330 target 'all' the prerequestive 'model-pic16' so it compiled the
9331 pic16 library, but now I've commented it out for the same reasons
9333 * added targets 'model-pic16' and 'objects-pic16' to compile the
9335 * added target 'port-specific-objects-pic16' to handle the
9336 generated libraries and copy them into the build/ directory
9337 * added target 'clean-intermediate-pic16' to clean intermediate
9338 files into pic16 directory
9339 * in target 'installdirs' added line to create directory pic16 in
9340 the installation path

9343 added lines to copy all header files to installation path,
9344 * in target 'installdirs' added line create directory for pic16
9345 headers in the installation path

9550 arguments via -W option
9551 * src/pic16/main.c: added $l in _asmCmd, changed extension for
9552 object file from '.rel' to '.o' in port->linker structure,

9584 * src/SDCCast.c (decorateType),
9585 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
9586 LEFT_OP (left shift)
9588 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9590 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9591 (default behaviour).
9593 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9595 A python script to validate compiler diagnostic messages. It can be
9596 used to verify that sdcc complains about bad c source code and
9597 gives a good location of the error.
9598 * support/valdiag/Makefile,
9599 * support/valdiag/valdiag.py,
9600 * support/valdiag/tests/*

9615 * src/common.h: added ifndef/define/endif macros
9616 around the header file.
9617 Bug reported from Jesus Calvino-Fraga
9619 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9621 * sdcc.spec: updated
9622 * device/include/Makefile.in: don't install CVS directories
9623 * device/lib/Makefile.in: added removal of CVS directories after install
9624 * doc/Makefile: fixed install, added local_icons
9625 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9626 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9627 * src/ds390/gen.c (genRightShift): fixed bug #870788
9628 * src/SDCCast.c (decorateType): fixed bug #870781
9630 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9632 PIC16 port related changes:
9633 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9634 added variable stackPos,
9636 * gen.c: genCall, assignResultValue: added support for
9637 pushing/retrieving function parameters to/from stack,
9638 genFunction,genEndFunction: setup stack frame for the
9640 genAddrOf: will be changed according to bug 863624
9642 * added files genutils.c and genutils.h which contain gen*
9643 debugged and optimised functions extracted from gen.c
9645 * glue.c: added variable 'externs' which holds extern symbols,
9646 pic16emitRegularMap: is modified to properly handle relocatable
9647 symbols under the new scheme,
9648 pic16createInterruptVect: is modified
9649 pic16printPublics: is modified to emit 'global' assembler directives,
9650 added pic16_printExterns to print extern symbols,
9651 pic16glue: initializes stack/frame pointer in the beginning of
9652 the assembly output. Temporary hack, will be corrected later,
9653 because gplink yet does not support stack and SDCC does not
9654 yet support a type of crt0.o object to create the final binary.
9656 * Removed many lines that contain 8051 legacy code.
9657 * The code is finally placed under a 'code' directive.
9658 * Added port specific options.
9660 * _process_pragma: simplified since now we do not need *special*
9661 include file to define SFR registers. But a separate header
9662 will be needed. This will be developed later.
9663 * _pic16_parseOptions: added, parses port specific options:
9664 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9665 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9666 --preplace-udata-with=
9668 * _pic16_setDefaultOptions: modified to initialize section names,
9669 but hack is temporarly out of order since it needs improvement.
9670 * _pic16_genAssemblerPreamble: configuration words are emitted by
9671 their address instead of their name. This part is incomplete and
9672 supports only the 18Fxx2 devices. Other devices will emit an error
9673 during assembly since they do not contain the same set of config
9675 * _pic16_genIVT: is modified,
9677 * pcode.c: added definitions for some hardware registers that are needed
9679 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9680 All PCI entries are updated. Now LFSR is supported.
9681 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9682 * added pic16_newpCodeOpLit2 to support instructions with
9683 two literal arguments
9684 * pic16_pCode2str: corrected code that emits assembler instructions
9685 with two literal operands and those that have an access bit modifier
9686 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9687 this fixes a bug which caused some labels to be lost, when an
9688 assembler directive was added, i.e. banksel,
9689 * pic16_FixRegisterBanking: improved logic that causes the insertion
9691 * InlineFunction: functions that are called once, are not any more
9692 inlined. This can be a port option in the future,
9694 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9696 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9697 hold the corresponding uninitialized symbols,
9698 * pic16_allocProcessorRegister: registers have explicit marked the
9700 * pic16_allocInternalRegister: registers are explicit marked as
9702 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9703 processing list, so bit registers were lost,
9706 * ralloc.h: added field 'accessBank' and original symbol operand
9707 in register definition,
9708 * removed the field isMapped from register definition,
9710 ** Several functions have been removed from various sources:
9711 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9712 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9713 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9714 pic16_assignRelocatableRegisters
9716 ** others have been introduced:
9717 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9718 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9720 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9722 * support/scripts/inc2h.pl: changed definition of BIT_AT
9723 to emit 'sbit at' instead of 'bit at'. This was a request.
9725 PIC16 port related preliminary changes:
9726 * gen.c: prefixed function popRegFromString with
9727 pic16_ and all references to it corrected
9728 * pcode.c: all pic16_pc_* hardware registers prefixed
9729 with underscore (_),
9730 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9731 * ralloc.c: newReg(): when register is REG_SFR then
9732 set address to rIdx,
9733 pic16_allocProcessorRegister(): marks register wasUsed=0
9734 pic16_writeUsedRegs(): added a call to assign processor
9735 registers via pic16_assignFixedRegisters
9737 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9739 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9740 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9741 variables in unused register banks. Also the SSEG is placed
9742 wherever there is enough space for it, and IDATA can be anywhere
9743 in internal RAM. For now compile using -Wl-Y[stack_size].
9744 The mem file is different for this option as well, since it
9745 makes no sense of talking about DSEG lenght.
9747 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9749 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9750 in certain cases, e.g. when ROM assignment, patch provided
9751 from Albert den Haan.

9992 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9994 * src/SDCCast.c (decorateType): disabled a transformation I added in
9995 revision 1.188 (access to fields of a structure at an absolute address);
9996 it breaks with bitfields, extern declarations, and gcse analysis.
9997 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9998 could be assigned through a pointer, so don't complain.
9999 * src/SDCCast.c (astErrors),
10001 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
10003 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

10009 pre-processor macro, i.e. -DMCU=p18f452
10010 * src/pic16/ralloc.c: renamed packRegisters to pic16_packRegisters,
10011 and modified to handle 'cast' icode similarly to '=' icode
10012 * src/pic16/device.h (typedef struct PIC_device): added field

10659 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10661 Fixed bug #621531 (const & volatile confusion in the type chain).
10662 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10663 refer to the const or volatile state of the pointer itself.
10675 * src/pic16/ralloc.c
10676 * support/regression/tests/const.c
10678 2003-09-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

10741 * src/mcs51/gen.c (leftRightUseAcc),
10742 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10743 iCode properly now. Use getSize instead of nRegs since a & b

10758 copied from genNearPointerSet()
10759 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10760 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10761 If they pop r0/r1 they must be called in the opposite order than aopOp().
10762 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10763 (resp. --stack-auto), prepared for --xstack
10765 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10767 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10769 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>

10774 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10776 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10777 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10778 type for bits was changed. It resulted in bit variables becoming
10779 global, which is not permitted in PIC 14 assembly output.
10781 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10783 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10785 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10787 Z80 and MCS51 linkers complaint if a public symbol is defined
10788 in more than one library module:
10792 * as/mcs51/Makefile.in
10794 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10796 A few small changes that speed up the peephole optimizer.
10800 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10802 Try to make the peephole optimizer smarter by maintaining
10803 an association between the assembly source code and the
10804 iCodes that originated them. Put this information to use
10805 with a new peephole rule condition "notVolatile" so that
10806 the rules can be aggressive yet still safe.
10811 * src/mcs51/peeph.def
10813 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10817 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10818 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10819 if the left or right operand symbols have the accuse flag set.
10821 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10823 Changed the type of the result of the ! (NOT) operator to char;
10824 previously it returned the same type as the source. This allows
10825 us to eliminate all the genFloatNot functions (all of its target
10826 implementations were very buggy) since !float can use the same
10829 * src/SDCCicode.c (ast2iCode): ! returns char
10830 * src/mcs51/gen.c (genNot, genNotFloat),
10831 * src/ds390/gen.c (genNot, genNotFloat),
10832 * src/z80/gen.c (genNot, genNotFloat),
10833 * src/pic/gen.c (genNot, genNotFloat),
10834 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
10836 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
10838 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10839 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10840 during interrupts. Ensure WSAVE is located at a shared bank address.
10841 2. Fixed page selection in some places
10842 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10843 the registers name strings.
10844 4. Fixed "signed / unsigned compare" compiler warnings.
10845 5. The PIC port manages its own allocation of the general purpose
10846 registers, but makes no attempt to reuse them. As a result when
10847 compiling it soon runs out of general purpose registers. Some
10848 additional code was added to the files pcode.c and device.c to walk
10849 through the function call tree and rename the registers so that they
10859 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10860 genPlus() & genMinus() when the result is the same as left or right
10862 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10866 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10868 Made bitfield a distinct type from bit so that bitfields
10869 convert as per ANSI C and bits retain their traditional
10870 boolean style behaviour. Implemented bitfield support in
10878 * src/ds390/gen.c: bit v bitfield split
10879 * src/z80/gen.c: New support for bitfields
10880 * support/regression/tests/bitfields.c: reenabled z80,
10883 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10885 Rules 246.x, 247.x relate to bitfields, the others speed up
10886 access to xdata mapped I/O devices.
10888 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10890 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10892 Cleaned up genPackBits and genUnpackBits and added two helper
10893 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10894 for literal assignments in genPackBits (thanks to Frieder for
10900 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10902 Fixed bug #748310 (pointer to function type mishandled when the
10903 function name is omitted). Also fixed a SIGSEGV when a function
10904 attribute (reentrant, etc) is used on a non-function or on a
10905 function but misplaced before the parameter list.
10907 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10909 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10910 * support/Util/SDCCerr.h,
10911 * support/Util/SDCCerr.c: Added func attr misuse error msg
10913 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10915 Fixed bug #787649 by anonymous
10916 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10917 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10919 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10921 Fixed numerous bitfield problems.
10923 * src/SDCC.y: More bitfield related error checking

10932 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10934 Made the constant following the "interrupt" keyword optional. If
10935 omitted, the function will not automatically be given an entry
10936 in the interrupt vector table (similar to #pragma NOIV, but
10937 less syntacticly kludgy). The interrupt number is also now
10938 range checked. Also fixed a bug in the high order bit example

10954 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10956 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10957 be re-activated by defining REDUCE_LITERALS)
10958 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10959 unsigned, but are signed by default
10960 * src/SDCCval.c (constVal): rearranged
10961 * src/SDCCval.c (valMod): preliminary fix
10962 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11002 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11003 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11004 constants are unsigned; added recognition of "u" flag for unsigned
11005 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11006 * src/SDCCval.c (valDiv, valMod): fixed signdness

11468 added if/endif conditional macros to remove options help
11469 messages from optionsTable when a port is not configured, added
11470 support for the PIc16 port in the ports table, when executing
11471 the compiler with no port specified on command line, a default
11472 port is selected with the new macro DEFAULT_PORT which is
11473 defined in port.h, in setDefaultOptions() linkOptions is removed
11474 from initialization assignment, since now it is a set,
11475 parseCmdLine uses setParseWithComma for linkOptions, in
11476 linkEdit() linkOptions are accessed with new function indexSet()
11477 which returns the i'th item of a set variable. See SDCCset.c, in
11478 linkEdit() when calling buildCmdLine(), added linkOptions as
11479 last argument. Now users can pass arguments to gplink via the
11480 -Wl option, main() uses pic16glue() to glue up pic16 programs

11493 * src/pic16/main.c: __config directives are commented out to stop
11494 gpasm complaining and test the linkage with gplink, _linkCmd and
11495 _asmCmd changed to be more gplink and gpasm friendly
11496 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11497 produced an error when parsed, peep rule 12 is added to utilize
11498 movff, but it is commented out since the pCode does not support
11499 yet a command with 2 address arguments
11501 2003-05-18 <johan AT balder>
11503 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12540 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
12541 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests

12551 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12552 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

12558 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
12559 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12561 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12562 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12564 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12566 * in /sdcc/as/mcs51/ changed these files in order to create an
12567 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12568 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12569 following files to include the previous two files: aslink.dsp,
12570 Makefile.aslink, Makefile.bcc, and Makefile.in.
12572 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12573 .adb instead of .cdb
12575 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12577 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12578 value from option --iram-size.
12580 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12582 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12585 2002-09-18 <wiml AT hhhh.org>
12587 * SDCClrange.h: exposed setFromRange() and setToRange()
12588 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12589 packRegsForAccUse() (bug 542397)
12590 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12591 multiple times and emitting the fetch operations more than once
12592 added aopGetUsesAcc() function to allow binary operators to
12593 fetch their operands in the correct order; made genMinus() emit
12594 compact code for X = LITERAL - Y
12596 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12597 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12598 sprintf() in line 1267.
12600 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12601 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12604 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12605 Changes to aslink (All the changes are marked with 'JCF'):
12607 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12610 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12611 area BSEG. Also moves, if possible, the DATA area down into the internal
12612 ram so more space is available.
12614 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12617 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12618 not bytes. Function summary() which creates a memory usage summary
12619 file with extension .mem. Reports of overlaping stack and small stack
12620 size. If the space for the stack is less than 16 bytes aslink trows a
12623 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12624 the 8051. Option 'y' for memory summary output file.
12626 Changes to sdcc (All the changes are marked with 'JCF'):
12628 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12630 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12631 overlaying area for it (uses RegBankUsed[4]).
12633 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12634 bank zero as used by default. By default aslink locates the stack
12635 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12636 the creation of the .mem file. Delegates the allocation of data area
12637 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12638 the begining of the stack area to aslink.
12640 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12641 glue() in SDCCglue.c creates an area for it.
12643 2002-09-03 Borut Razem <borut.razem AT siol.net>
12644 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12645 sdcc/src/pic/glue.c:
12646 introduced atexit() handler for teporay files removal in case of
12647 errors, assertions, ...
12649 2002-08-29 Borut Razem <borut.razem AT siol.net>
12650 * sdcc/support/cpp2/auto-host_vc_in.h:
12651 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12652 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12653 Maybe there is a similar problem with BORLANDC? It should be checked!
12655 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12656 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12657 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12658 was not executed, and the compiler (cl) launched a warning:
12659 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12661 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12662 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12664 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12665 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12667 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12668 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12669 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12670 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12671 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12672 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12673 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12674 - added Release configuration in VS projects
12675 - review of compiler an linker options
12676 - VC .exe files are generated in bin_vc directory, not to interfere
12677 with binaries generated from other projects (cygwin, mingw, bcc ...)
12679 * sdcc/src/yacc.dsp: added
12681 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12682 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12683 and insert the version number definitions from .version
12685 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12687 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12688 added - genarate auto-host.h using auto-host_vc_in.h as template
12691 removed from CVS, generated automatically
12693 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12694 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12696 2002-08-11 Borut Razem <borut.razem AT siol.net>
12697 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12699 2002-08-10 Borut Razem <borut.razem AT siol.net>
12700 * src/SDCCmain.c (main):
12701 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12702 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12703 The consequence was that some temporary files were not removed.
12706 unification of code in functions tempfilename() and tempfile():
12707 function tempnam() is defined in Visual Studio 6.0 and .NET
12709 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12711 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12712 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12713 - removed compiler command line option /WX: Treats all warnings as errors
12714 - update a list of source files, included into the project
12716 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12717 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12718 changed project type to Generic Project so that can be correcly converted to VS.NET project
12720 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12722 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12724 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12726 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12727 added return 0 statements after assert() to make compiler happy
12729 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12730 added newline in the def file to keep MSC compiler satisfied
12732 * sdcc/src/z80/gen.c:
12733 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12734 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12735 - solved MSC error in function aopDump()
12737 * sdcc_vc.h: define PREFIX as "\\sdcc"
12739 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12740 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
12742 2002-06-22 Scott Dattalo <scott AT dattalo.com>
12743 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12744 - Rewrote the register banking algorithm.
12745 - Added pCode live-range analysis to registers (for now, only non-used and
12746 singly-used registers optimized away)
12748 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12750 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
12752 2002-05-10 Scott Dattalo <scott AT dattalo.com>
12753 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

12765 2002-04-15 Michael Hope <michaelh AT vroom>
12767 * device/lib/z80/printf.c (sprintf): Added.
12769 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
12771 * src/z80/peeph.def: Added transpose redundent load rule.
