1899 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1900 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1901 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1902 always available in leading double underscore form. The C99 support is
1903 mostly missing, but it's a start.
1904 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1905 reserved identifier "__data".

1983 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1985 * device/lib/printf_large.c: removed inline assembly for portability and
1986 readability. Use printf_fast if speed or size are more important.
1987 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1988 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1990 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1992 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1993 prevent compiler warning
1995 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1997 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1998 moved to level 0 and declared as static. Also they are explicit
1999 placed in access bank. This was necessery because some times they
2000 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2001 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2002 optimizations. Currently only compare to unsigned char is implemented,
2003 * src/pic16/gen.c: added fReturnIdx array,
2004 * (struct resolvedIfx) is moved to gen.h and made public,
2005 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2006 * (aopForSym): added an optimization to directly store in stack of
2007 the operand of a SEND iCode,
2008 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2009 but as registers instead (AOP_REG) using the fReturnIdx array,
2010 * (pic16_freeAsmop): remove the freed register from the
2011 _G.sregsAlloc field,
2012 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2013 a compare of 'WREG',
2014 * (pic16_popGetTempRegCond): changed function prototype, now
2015 function takes also a bitVector argument v which holds the current
2016 set of registers that are allocated for stack access by aopForSym,
2017 registers allocated in aopForSym for accessing stack symbols are not
2018 any more part of the functions usedRegs field,
2019 * (genCall): some times aopOp is called for a stack variable to be
2020 send, aopForSym might perform the push, if this is true make sure
2021 that genCall doesn't push the variable twice by testing _G.resDirect,
2022 * (genFunction): changed testing for unspecified interrupt number
2023 from 256 to INTNO_UNSPEC,
2024 * modified selection scheme of frame pointer generation. Previously
2025 if function did use local registers a frame pointer was generated,
2026 now a frame pointer is generated only if function has arguments
2027 (that need PLUSW2 register access), or has stack arguments, or the
2028 compiler is not instructed to omit the frame pointer,
2029 * (genEndFunction): before restoring local registers that were saved
2030 in the function preamble, also restore the registers that *might*
2031 have been allocated for stack access,
2032 * (genRet): removed some old comments,
2033 * (genCmp, the active (RN's) version): added a call to the
2034 pic16_genCmp_special function to perform the compare with a more
2035 robust and optimized way,
2036 * (genInline): a feature has been added in inline code generation,
2037 which allows a wildcard variable substitution when writing inline
2038 assembly. Code is incomplete and experimental therefore undocumented,
2039 * (genCast): changed order of aopOp for result and right to allow
2040 aopForSym to directly load the result if possible,
2041 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2042 perform an optimized compare on some selected special occasions,
2043 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2044 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2045 generate an IVT any more,
2046 * src/pic16/main.c (pic16_optionsTable): added command line option
2048 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2049 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2051 * src/pic16/NOTES: Raphael Neider added in list of active developers
2052 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2053 jumptable_end to prevent bug #,
2054 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2055 inCond and outCond fields,
2056 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2057 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2058 turn off register spilling,
2059 * (packRegsForOneUse): synced with other ports' versions although it
2060 is not used currently,
2061 * (pic16_packRegisters): added an optimization while reading
2062 structure bitfields, some registers may be saved (malloc code is
2063 decreased by 80 bytes)
2065 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2067 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2068 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2069 this can be optimized more?
2071 2005-03-10 Raphael Neider <rneider AT web.de>
2073 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2074 genNearPointerGet): (hopefully) fixed access to bitfields via
2075 pointers (p->bitN = x; and x = p->bitN; failed)

2709 Adding support for replacing ljmps with sjmps in jumptables
2710 generated for switch statements. For now you need to set the
2711 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2712 Now 4 algorithms for mcs51 jumptable generation are used:
2713 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2714 addresses loaded pc-relative for up to 112 cases and stack-pushing
2715 target addresses loaded with offset from dptr for up to 256 cases.

2745 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2747 * added libc directory. The current version of LibC contains string
2748 functions, ctype functions and macros and some functions of the
2749 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2750 be extensively tested in the future. Standard disclaimer here.
2751 Library is not automatically build yet. But one can build it by
2752 invoking 'make' inside the libc directory.

2763 * (pic16_storeForReturn): optimized return of 0,
2764 * (genCmp): experimental code for new genCmp which uses PIC18's
2765 special compare&skip instructions. Initial tests fail some times
2766 with variables grater than 1 byte in size, so new code is disabled,
2767 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2769 * (genCast): began a fix to optimize the casting of a bit to another
2770 bit, now assigning a bitfield to another bitfield will fail, sorry,

2779 and 1 for banking instruction,
2780 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2781 caused stop processing pCodes after a inline assembly block,
2782 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2784 registers when it shouldn't,
2785 * src/pic16/ralloc.c (allocReg): add preliminary support for
2786 supporting a limited set of temporary registers,
2788 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5676 2004-01-27 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5678 * ChangeLog: changed "@" to " AT " in hopes of reducing spam and
5679 virus/worm forged address usage.
5681 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
5683 Fixed promotion, it should be done on AST level:
5684 * src/SDCCast.c (addCast): added promotion to int
5685 (decorateType): updated call to upCast()
5686 * src/SDCCicode.c (geniCodeLeftShift): removed call to
5687 usualUnaryConversions()
5689 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
5691 * support/regression/tests/literalop.c (mulWrapper): Added a
5692 wrapper to remove integer overflow warnings.

5696 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
5699 * support/regression/generate-cases.py (main): Changed from inline
5702 * doc/Makefile (install): Changed to depth first to get rid of
5703 missing directory install warning.
5705 * as/Makefile (install-doc): Made work on Mac.
5707 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
5709 * src/SDCCast.c: added an additional type flow in decorateType() of
5710 opposite direction, see feature request #860006; it's enabled at runtime
5711 by setting the environment variable SDCC_NEWTYPEFLOW
5712 * src/SDCCast.h: changed prototype of decorateType()
5713 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
5714 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
5715 'char' to 'int' can be omitted, if both operands are 'unsigned char';
5716 see feature request #877103
5717 * src/SDCCval.c: updated call of decorateType()
5718 (valBitwise): fixed bug #882876
5719 (valMinus): added promotion
5720 (valLogicAndOr): result is unsigned
5721 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
5722 * src/SDCCsymt.c (computeType),
5723 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'

5745 * src/pic/ralloc.h: applied patch from Slade Rich;
5746 added support for multiple code pages and multiple RAM banks on the
5747 PIC 14 port. The ASM files now no longer simply assume all the
5748 code / RAM are in the same page / bank. This means the linker can
5749 safely allocate code/RAM of separate ASM files to different pages/banks.
5750 * doc/sdccman.lyx: added Slade's tips
5751 * src/mcs51/peeph.def: fixed bug #880768

5763 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
5764 strtof is not part of C89 and isn't included with Mac OS X.
5766 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5768 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

5793 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5795 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5796 loaded with the linker search paths (-L arguments) and the libraries
5797 to be linked with the current source (-l arguments). Changes
5798 currently will affect only the pic16 port.
5799 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5800 include path the port specific paths and port specific libraries,
5801 * gplink command now contains the $3 argument,
5802 * src/pic16/device.h,
5803 * src/pic16/device.c,: structure PIC_device is made public and
5804 renamed to PIC16_device, the same for variable Pics which is renamed

5819 Documenting changes from previous commits.
5820 * configure.in (version 1.56),
5821 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5822 when generating output files to configure the pic16 library,
5823 but now I've commented it out, since gputils aren't installed in the
5824 SF compile farm, so library won't compile
5826 * device/lib/Makefile.in (version 1.56): initially I've added in
5827 target 'all' the prerequestive 'model-pic16' so it compiled the
5828 pic16 library, but now I've commented it out for the same reasons
5830 * added targets 'model-pic16' and 'objects-pic16' to compile the
5832 * added target 'port-specific-objects-pic16' to handle the
5833 generated libraries and copy them into the build/ directory
5834 * added target 'clean-intermediate-pic16' to clean intermediate
5835 files into pic16 directory
5836 * in target 'installdirs' added line to create directory pic16 in
5837 the installation path
5839 * device/include/Makefile.in (version 1.11): in target 'install'
5840 added lines to copy all header files to installation path,
5841 * in target 'installdirs' added line create directory for pic16
5842 headers in the installation path

5857 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5858 option so that it actually works. Made it specific to the z80, since
5859 the gbz80 doesn't have these kinds of I/O ports.
5861 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5863 * device/include/z180.h,

5885 Mainly changes to support compilation of the device libraries
5886 * src/pic16/device.c: stack is allocated via symbol and not
5887 via literal number. The symbol is placed in the corresponding
5888 position of the data ram
5889 * (pic16_dump_section): relocatable and absolute uninitialized
5890 data are now emitted in sorted order to reduce section naming,
5891 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5892 weren't marked as being in the access bank,
5894 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5896 Added portion of GNU PIC Library under the directory
5897 device/include/pic16 and device/lib/pic16. These files
5898 contain the declarations of SFRs for the PIC18Fxx2 devices.
5899 The directory is initialized via configure from toplevel.
5901 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
5903 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

5929 all over. Telling LaTeX to be less strict with word spacing
5930 to better keep the right margin. Changed some notes about
5931 maintainance of the ports in section 3.2.1 - is it OK like this?
5933 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5973 * src/pic16/peeph.def: all peepholes with movff are commented out,
5974 because there is a problem in the pcode peep optimizer,
5975 * src/pic16/ralloc.c: the register allocator can now reuse local

6040 directive when no overlay data exist
6041 * (picglue): modified to emit uninitialized data segment
6042 according to udata_section_name

6114 Bug reported from Jesus Calvino-Fraga
6116 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6118 * sdcc.spec: updated
6119 * device/include/Makefile.in: don't install CVS directories
6120 * device/lib/Makefile.in: added removal of CVS directories after install
6121 * doc/Makefile: fixed install, added local_icons
6122 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6123 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6124 * src/ds390/gen.c (genRightShift): fixed bug #870788

6127 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6129 PIC16 port related changes:
6130 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6131 added variable stackPos,
6133 * gen.c: genCall, assignResultValue: added support for
6134 pushing/retrieving function parameters to/from stack,
6135 genFunction,genEndFunction: setup stack frame for the
6137 genAddrOf: will be changed according to bug 863624
6139 * added files genutils.c and genutils.h which contain gen*
6140 debugged and optimised functions extracted from gen.c
6142 * glue.c: added variable 'externs' which holds extern symbols,
6143 pic16emitRegularMap: is modified to properly handle relocatable
6144 symbols under the new scheme,
6145 pic16createInterruptVect: is modified
6146 pic16printPublics: is modified to emit 'global' assembler directives,
6147 added pic16_printExterns to print extern symbols,
6148 pic16glue: initializes stack/frame pointer in the beginning of
6149 the assembly output. Temporary hack, will be corrected later,
6150 because gplink yet does not support stack and SDCC does not
6151 yet support a type of crt0.o object to create the final binary.
6153 * Removed many lines that contain 8051 legacy code.
6154 * The code is finally placed under a 'code' directive.
6155 * Added port specific options.
6157 * _process_pragma: simplified since now we do not need *special*
6158 include file to define SFR registers. But a separate header
6159 will be needed. This will be developed later.
6160 * _pic16_parseOptions: added, parses port specific options:
6161 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6162 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6163 --preplace-udata-with=
6165 * _pic16_setDefaultOptions: modified to initialize section names,
6166 but hack is temporarly out of order since it needs improvement.
6167 * _pic16_genAssemblerPreamble: configuration words are emitted by
6168 their address instead of their name. This part is incomplete and
6169 supports only the 18Fxx2 devices. Other devices will emit an error
6170 during assembly since they do not contain the same set of config
6172 * _pic16_genIVT: is modified,
6174 * pcode.c: added definitions for some hardware registers that are needed
6176 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6177 All PCI entries are updated. Now LFSR is supported.
6178 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6179 * added pic16_newpCodeOpLit2 to support instructions with
6180 two literal arguments
6181 * pic16_pCode2str: corrected code that emits assembler instructions
6182 with two literal operands and those that have an access bit modifier
6183 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6184 this fixes a bug which caused some labels to be lost, when an
6185 assembler directive was added, i.e. banksel,
6186 * pic16_FixRegisterBanking: improved logic that causes the insertion
6188 * InlineFunction: functions that are called once, are not any more
6189 inlined. This can be a port option in the future,
6191 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6193 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6194 hold the corresponding uninitialized symbols,
6195 * pic16_allocProcessorRegister: registers have explicit marked the
6197 * pic16_allocInternalRegister: registers are explicit marked as
6199 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6200 processing list, so bit registers were lost,
6203 * ralloc.h: added field 'accessBank' and original symbol operand
6204 in register definition,
6205 * removed the field isMapped from register definition,
6207 ** Several functions have been removed from various sources:
6208 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6209 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6210 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6211 pic16_assignRelocatableRegisters
6213 ** others have been introduced:
6214 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6215 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6217 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6219 * support/scripts/inc2h.pl: changed definition of BIT_AT
6220 to emit 'sbit at' instead of 'bit at'. This was a request.
6222 PIC16 port related preliminary changes:
6223 * gen.c: prefixed function popRegFromString with
6224 pic16_ and all references to it corrected
6225 * pcode.c: all pic16_pc_* hardware registers prefixed
6226 with underscore (_),
6227 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6228 * ralloc.c: newReg(): when register is REG_SFR then
6229 set address to rIdx,
6230 pic16_allocProcessorRegister(): marks register wasUsed=0
6231 pic16_writeUsedRegs(): added a call to assign processor
6232 registers via pic16_assignFixedRegisters
6234 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6236 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6237 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6238 variables in unused register banks. Also the SSEG is placed
6239 wherever there is enough space for it, and IDATA can be anywhere
6240 in internal RAM. For now compile using -Wl-Y[stack_size].
6241 The mem file is different for this option as well, since it
6242 makes no sense of talking about DSEG lenght.
6244 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6246 * src/SDCClrange.c: fixed bug 869095 that caused segfault

6491 * src/SDCCast.c (decorateType): disabled a transformation I added in
6492 revision 1.188 (access to fields of a structure at an absolute address);
6493 it breaks with bitfields, extern declarations, and gcse analysis.
6494 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6495 could be assigned through a pointer, so don't complain.

6603 xdata initialization slightly shorter
6605 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7159 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
7160 refer to the const or volatile state of the pointer itself.

7252 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7253 fetching of the pointer
7254 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7255 copied from genNearPointerSet()
7256 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7257 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7273 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7274 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7275 type for bits was changed. It resulted in bit variables becoming
7276 global, which is not permitted in PIC 14 assembly output.
7278 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7280 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7293 A few small changes that speed up the peephole optimizer.
7297 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7299 Try to make the peephole optimizer smarter by maintaining
7300 an association between the assembly source code and the
7301 iCodes that originated them. Put this information to use
7302 with a new peephole rule condition "notVolatile" so that
7303 the rules can be aggressive yet still safe.
7308 * src/mcs51/peeph.def
7310 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7314 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7315 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7316 if the left or right operand symbols have the accuse flag set.
7318 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7320 Changed the type of the result of the ! (NOT) operator to char;
7321 previously it returned the same type as the source. This allows
7322 us to eliminate all the genFloatNot functions (all of its target
7323 implementations were very buggy) since !float can use the same
7326 * src/SDCCicode.c (ast2iCode): ! returns char

7335 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7336 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7337 during interrupts. Ensure WSAVE is located at a shared bank address.
7338 2. Fixed page selection in some places
7339 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7340 the registers name strings.
7341 4. Fixed "signed / unsigned compare" compiler warnings.
7342 5. The PIC port manages its own allocation of the general purpose
7343 registers, but makes no attempt to reuse them. As a result when
7344 compiling it soon runs out of general purpose registers. Some
7345 additional code was added to the files pcode.c and device.c to walk
7346 through the function call tree and rename the registers so that they
7356 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7357 genPlus() & genMinus() when the result is the same as left or right

7363 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7365 Made bitfield a distinct type from bit so that bitfields
7366 convert as per ANSI C and bits retain their traditional
7367 boolean style behaviour. Implemented bitfield support in
7375 * src/ds390/gen.c: bit v bitfield split
7376 * src/z80/gen.c: New support for bitfields
7377 * support/regression/tests/bitfields.c: reenabled z80,
7380 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7382 Rules 246.x, 247.x relate to bitfields, the others speed up
7383 access to xdata mapped I/O devices.
7385 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7387 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7389 Cleaned up genPackBits and genUnpackBits and added two helper
7390 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7391 for literal assignments in genPackBits (thanks to Frieder for
7397 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7399 Fixed bug #748310 (pointer to function type mishandled when the
7400 function name is omitted). Also fixed a SIGSEGV when a function
7401 attribute (reentrant, etc) is used on a non-function or on a
7402 function but misplaced before the parameter list.
7404 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7406 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7407 * support/Util/SDCCerr.h,

7429 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7431 Made the constant following the "interrupt" keyword optional. If
7432 omitted, the function will not automatically be given an entry
7433 in the interrupt vector table (similar to #pragma NOIV, but
7434 less syntacticly kludgy). The interrupt number is also now
7435 range checked. Also fixed a bug in the high order bit example

7443 * support/Util/SDCCerr.h
7446 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7449 * src/SDCCicode.c (operandOperation): rewritten some ops
7450 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7451 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7453 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7454 be re-activated by defining REDUCE_LITERALS)
7455 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7456 unsigned, but are signed by default
7457 * src/SDCCval.c (constVal): rearranged
7458 * src/SDCCval.c (valMod): preliminary fix
7459 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7501 constants are unsigned; added recognition of "u" flag for unsigned
7502 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7503 * src/SDCCval.c (valDiv, valMod): fixed signdness
7504 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7505 signedness of modulo, left and right shift

7964 * src/SDCCmain.c: linkOptions is changed to set *,
7965 added if/endif conditional macros to remove options help
7966 messages from optionsTable when a port is not configured, added
7967 support for the PIc16 port in the ports table, when executing
7968 the compiler with no port specified on command line, a default
7969 port is selected with the new macro DEFAULT_PORT which is
7970 defined in port.h, in setDefaultOptions() linkOptions is removed
7971 from initialization assignment, since now it is a set,
7972 parseCmdLine uses setParseWithComma for linkOptions, in
7973 linkEdit() linkOptions are accessed with new function indexSet()
7974 which returns the i'th item of a set variable. See SDCCset.c, in
7975 linkEdit() when calling buildCmdLine(), added linkOptions as
7976 last argument. Now users can pass arguments to gplink via the
7977 -Wl option, main() uses pic16glue() to glue up pic16 programs

7989 * src/pic16/glue.c: commented out some error producing lines
7990 * src/pic16/main.c: __config directives are commented out to stop
7991 gpasm complaining and test the linkage with gplink, _linkCmd and
7992 _asmCmd changed to be more gplink and gpasm friendly
7993 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7994 produced an error when parsed, peep rule 12 is added to utilize
7995 movff, but it is commented out since the pCode does not support
7996 yet a command with 2 address arguments
7998 2003-05-18 <johan AT balder>
8000 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8027 2003-05-11 Borut Razem <borut.razem AT siol.net>
8029 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8030 the path of bin directory, so that PATH is the only env. variable, which has to be set
8031 in case of standard installation.

9093 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9094 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9095 sprintf() in line 1267.
9097 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9098 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9101 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9102 Changes to aslink (All the changes are marked with 'JCF'):
9104 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9107 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9108 area BSEG. Also moves, if possible, the DATA area down into the internal
9109 ram so more space is available.
9111 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9114 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9115 not bytes. Function summary() which creates a memory usage summary
9116 file with extension .mem. Reports of overlaping stack and small stack
9117 size. If the space for the stack is less than 16 bytes aslink trows a
9120 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9121 the 8051. Option 'y' for memory summary output file.
9123 Changes to sdcc (All the changes are marked with 'JCF'):
9125 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9127 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9128 overlaying area for it (uses RegBankUsed[4]).
9130 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9131 bank zero as used by default. By default aslink locates the stack
9132 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9133 the creation of the .mem file. Delegates the allocation of data area
9134 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9135 the begining of the stack area to aslink.
9137 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9138 glue() in SDCCglue.c creates an area for it.
9140 2002-09-03 Borut Razem <borut.razem AT siol.net>
9141 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9142 sdcc/src/pic/glue.c:
9143 introduced atexit() handler for teporay files removal in case of
9144 errors, assertions, ...
9146 2002-08-29 Borut Razem <borut.razem AT siol.net>
9147 * sdcc/support/cpp2/auto-host_vc_in.h:
9148 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9149 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9150 Maybe there is a similar problem with BORLANDC? It should be checked!
9152 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9153 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9154 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9155 was not executed, and the compiler (cl) launched a warning:
9156 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9158 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9159 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9161 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9162 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9164 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9165 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9166 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9167 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9168 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9169 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9170 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9171 - added Release configuration in VS projects
9172 - review of compiler an linker options
9173 - VC .exe files are generated in bin_vc directory, not to interfere
9174 with binaries generated from other projects (cygwin, mingw, bcc ...)
9176 * sdcc/src/yacc.dsp: added
9178 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9179 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9180 and insert the version number definitions from .version
9182 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9184 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9185 added - genarate auto-host.h using auto-host_vc_in.h as template
9188 removed from CVS, generated automatically
9190 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9191 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9193 2002-08-11 Borut Razem <borut.razem AT siol.net>
9194 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9196 2002-08-10 Borut Razem <borut.razem AT siol.net>
9197 * src/SDCCmain.c (main):
9198 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9199 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9200 The consequence was that some temporary files were not removed.
9203 unification of code in functions tempfilename() and tempfile():
9204 function tempnam() is defined in Visual Studio 6.0 and .NET
9206 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9208 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9209 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9210 - removed compiler command line option /WX: Treats all warnings as errors
9211 - update a list of source files, included into the project
9213 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9214 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9215 changed project type to Generic Project so that can be correcly converted to VS.NET project
9217 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9219 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9221 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9223 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9224 added return 0 statements after assert() to make compiler happy
9226 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9227 added newline in the def file to keep MSC compiler satisfied
9229 * sdcc/src/z80/gen.c:
9230 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9231 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9232 - solved MSC error in function aopDump()
9234 * sdcc_vc.h: define PREFIX as "\\sdcc"
9236 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9237 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9240 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9241 - Rewrote the register banking algorithm.
9242 - Added pCode live-range analysis to registers (for now, only non-used and
9243 singly-used registers optimized away)
9245 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

9276 2002-03-28 Johan Knol <johan AT balder>
9278 * src/SDCCval.c: fixed bug #532436
9280 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9282 Added "char *Processor" field to the port structure.
9285 Added -p option. Allows port dependent processor to be specified.
9288 Initialized the new field char *Processor field to NULL in all ports
9291 Compiler generated registers for interrupt context saving
9292 were not getting allocated.
9294 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9297 Fixed left shift. Will promote the left side of a left shift
9298 if a) left shifting more than size of operand or b) when assigned
9299 to something size > size of left side
9301 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9303 tons of changes. Register allocation has been
9304 rewritten. Added customization for the various PICs. Flow

9409 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9411 * sdcc/src/SDCCloop.c:
9412 Previous fix was not good. basic blocks that have "break" or "return" are
9413 not really partof a loop , but live ranges used in these blocks should
9414 be live thru the entire loop, so set partOfLoop but don't add them to
9417 2002-02-21 <johan AT FRIJA>
9419 * src/SDCCcse.c: fixed bug #514308
9421 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9424 Fixed BUG #519583. If a conditional block ended in a return/break
9425 statement inside a loop, it was not being considered part of the loop.
9427 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9429 2002-02-10 Karl Bongers <karl AT turbobit.com>
9432 Fixed up SDCDB debugger somewhat. Updated debugger/README
9433 with lots of comments and notes.
9435 * device/examples/test2.c:
9436 Fix bug, "red" variable not being initialized(compiler complained).

9440 for use as a multiple module SDCDB test case.
9442 * sim/ucsim/cmd.src/cmdset.cc:
9443 Took out debug printfs in ucsim "next" command.
9446 Karl and Johan start ucsim XA support. Most dissassembly working,
9447 about 75% emulation done(plenty of work remaining).
9449 * sim/ucsim/z80.src:
9450 Add Z80 support to ucsim, add test-ucz80 regression test,
9451 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
