900 placed in access bank. This was necessery because some times they
901 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
902 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
903 optimizations. Currently only compare to unsigned char is implemented,
904 * src/pic16/gen.c: added fReturnIdx array,
905 * (struct resolvedIfx) is moved to gen.h and made public,
906 * (struct _G): added sregsAlloc and sregsAllocSet fields,
907 * (aopForSym): added an optimization to directly store in stack of
908 the operand of a SEND iCode,
909 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
910 but as registers instead (AOP_REG) using the fReturnIdx array,
911 * (pic16_freeAsmop): remove the freed register from the
913 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
915 * (pic16_popGetTempRegCond): changed function prototype, now
916 function takes also a bitVector argument v which holds the current
917 set of registers that are allocated for stack access by aopForSym,
918 registers allocated in aopForSym for accessing stack symbols are not
919 any more part of the functions usedRegs field,
920 * (genCall): some times aopOp is called for a stack variable to be
921 send, aopForSym might perform the push, if this is true make sure
922 that genCall doesn't push the variable twice by testing _G.resDirect,
923 * (genFunction): changed testing for unspecified interrupt number
924 from 256 to INTNO_UNSPEC,
925 * modified selection scheme of frame pointer generation. Previously
926 if function did use local registers a frame pointer was generated,
927 now a frame pointer is generated only if function has arguments
928 (that need PLUSW2 register access), or has stack arguments, or the
929 compiler is not instructed to omit the frame pointer,
930 * (genEndFunction): before restoring local registers that were saved
931 in the function preamble, also restore the registers that *might*
932 have been allocated for stack access,
933 * (genRet): removed some old comments,
934 * (genCmp, the active (RN's) version): added a call to the
935 pic16_genCmp_special function to perform the compare with a more
936 robust and optimized way,
937 * (genInline): a feature has been added in inline code generation,
938 which allows a wildcard variable substitution when writing inline
939 assembly. Code is incomplete and experimental therefore undocumented,
940 * (genCast): changed order of aopOp for result and right to allow
941 aopForSym to directly load the result if possible,
942 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
943 perform an optimized compare on some selected special occasions,
944 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
945 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
946 generate an IVT any more,
947 * src/pic16/main.c (pic16_optionsTable): added command line option
949 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
950 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
952 * src/pic16/NOTES: Raphael Neider added in list of active developers
953 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
954 jumptable_end to prevent bug #,
955 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
956 inCond and outCond fields,
957 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
958 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
959 turn off register spilling,
960 * (packRegsForOneUse): synced with other ports' versions although it
961 is not used currently,
962 * (pic16_packRegisters): added an optimization while reading
963 structure bitfields, some registers may be saved (malloc code is
964 decreased by 80 bytes)
966 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
968 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
969 left is a bitfield, if yes, then don't optimize assignment. Perhaps
970 this can be optimized more?
972 2005-03-10 Raphael Neider <rneider AT web.de>
974 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
975 genNearPointerGet): (hopefully) fixed access to bitfields via
976 pointers (p->bitN = x; and x = p->bitN; failed)

1302 access stack and frame pointers. They are initially assigned to
1303 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
1304 accessing SFRs. Updated all occurences of modification of stack or
1305 frame pointer in gen.c and pcode.c,

1610 Adding support for replacing ljmps with sjmps in jumptables
1611 generated for switch statements. For now you need to set the
1612 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1613 Now 4 algorithms for mcs51 jumptable generation are used:
1614 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1615 addresses loaded pc-relative for up to 112 cases and stack-pushing
1616 target addresses loaded with offset from dptr for up to 256 cases.

1649 functions, ctype functions and macros and some functions of the
1650 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1651 be extensively tested in the future. Standard disclaimer here.

1666 special compare&skip instructions. Initial tests fail some times
1667 with variables grater than 1 byte in size, so new code is disabled,
1668 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1670 * (genCast): began a fix to optimize the casting of a bit to another
1671 bit, now assigning a bitfield to another bitfield will fail, sorry,

4697 loaded with the linker search paths (-L arguments) and the libraries
4698 to be linked with the current source (-l arguments). Changes
4699 currently will affect only the pic16 port.
4700 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4701 include path the port specific paths and port specific libraries,
4702 * gplink command now contains the $3 argument,
4703 * src/pic16/device.h,
4704 * src/pic16/device.c,: structure PIC_device is made public and
4705 renamed to PIC16_device, the same for variable Pics which is renamed

4720 Documenting changes from previous commits.
4721 * configure.in (version 1.56),
4722 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4723 when generating output files to configure the pic16 library,
4724 but now I've commented it out, since gputils aren't installed in the
4725 SF compile farm, so library won't compile
4727 * device/lib/Makefile.in (version 1.56): initially I've added in
4728 target 'all' the prerequestive 'model-pic16' so it compiled the
4729 pic16 library, but now I've commented it out for the same reasons
4731 * added targets 'model-pic16' and 'objects-pic16' to compile the
4733 * added target 'port-specific-objects-pic16' to handle the
4734 generated libraries and copy them into the build/ directory
4735 * added target 'clean-intermediate-pic16' to clean intermediate
4736 files into pic16 directory
4737 * in target 'installdirs' added line to create directory pic16 in

4759 option so that it actually works. Made it specific to the z80, since
4760 the gbz80 doesn't have these kinds of I/O ports.
4762 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4764 * device/include/z180.h,

4791 data are now emitted in sorted order to reduce section naming,
4792 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4793 weren't marked as being in the access bank,

4986 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4988 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4989 (default behaviour).
4991 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4993 A python script to validate compiler diagnostic messages. It can be
4994 used to verify that sdcc complains about bad c source code and
4995 gives a good location of the error.
4996 * support/valdiag/Makefile,
4997 * support/valdiag/valdiag.py,
4998 * support/valdiag/tests/*

5017 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5019 * sdcc.spec: updated
5020 * device/include/Makefile.in: don't install CVS directories
5021 * device/lib/Makefile.in: added removal of CVS directories after install
5022 * doc/Makefile: fixed install, added local_icons
5023 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5024 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5025 * src/ds390/gen.c (genRightShift): fixed bug #870788

5028 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5030 PIC16 port related changes:
5031 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5032 added variable stackPos,
5034 * gen.c: genCall, assignResultValue: added support for
5035 pushing/retrieving function parameters to/from stack,
5036 genFunction,genEndFunction: setup stack frame for the
5038 genAddrOf: will be changed according to bug 863624
5040 * added files genutils.c and genutils.h which contain gen*
5041 debugged and optimised functions extracted from gen.c
5043 * glue.c: added variable 'externs' which holds extern symbols,
5044 pic16emitRegularMap: is modified to properly handle relocatable
5045 symbols under the new scheme,
5046 pic16createInterruptVect: is modified
5047 pic16printPublics: is modified to emit 'global' assembler directives,
5048 added pic16_printExterns to print extern symbols,
5049 pic16glue: initializes stack/frame pointer in the beginning of
5050 the assembly output. Temporary hack, will be corrected later,
5051 because gplink yet does not support stack and SDCC does not
5052 yet support a type of crt0.o object to create the final binary.
5054 * Removed many lines that contain 8051 legacy code.
5055 * The code is finally placed under a 'code' directive.
5056 * Added port specific options.
5058 * _process_pragma: simplified since now we do not need *special*
5059 include file to define SFR registers. But a separate header
5060 will be needed. This will be developed later.
5061 * _pic16_parseOptions: added, parses port specific options:
5062 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5063 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5064 --preplace-udata-with=
5066 * _pic16_setDefaultOptions: modified to initialize section names,
5067 but hack is temporarly out of order since it needs improvement.
5068 * _pic16_genAssemblerPreamble: configuration words are emitted by
5069 their address instead of their name. This part is incomplete and
5070 supports only the 18Fxx2 devices. Other devices will emit an error
5071 during assembly since they do not contain the same set of config
5073 * _pic16_genIVT: is modified,
5075 * pcode.c: added definitions for some hardware registers that are needed
5077 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5078 All PCI entries are updated. Now LFSR is supported.
5079 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5080 * added pic16_newpCodeOpLit2 to support instructions with
5081 two literal arguments
5082 * pic16_pCode2str: corrected code that emits assembler instructions
5083 with two literal operands and those that have an access bit modifier
5084 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5085 this fixes a bug which caused some labels to be lost, when an
5086 assembler directive was added, i.e. banksel,
5087 * pic16_FixRegisterBanking: improved logic that causes the insertion
5089 * InlineFunction: functions that are called once, are not any more
5090 inlined. This can be a port option in the future,
5092 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5094 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5095 hold the corresponding uninitialized symbols,
5096 * pic16_allocProcessorRegister: registers have explicit marked the
5098 * pic16_allocInternalRegister: registers are explicit marked as
5100 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5101 processing list, so bit registers were lost,
5104 * ralloc.h: added field 'accessBank' and original symbol operand
5105 in register definition,
5106 * removed the field isMapped from register definition,
5108 ** Several functions have been removed from various sources:
5109 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5110 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5111 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5112 pic16_assignRelocatableRegisters
5114 ** others have been introduced:
5115 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5116 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5118 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5120 * support/scripts/inc2h.pl: changed definition of BIT_AT
5121 to emit 'sbit at' instead of 'bit at'. This was a request.
5123 PIC16 port related preliminary changes:
5124 * gen.c: prefixed function popRegFromString with
5125 pic16_ and all references to it corrected
5126 * pcode.c: all pic16_pc_* hardware registers prefixed
5127 with underscore (_),
5128 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5129 * ralloc.c: newReg(): when register is REG_SFR then
5130 set address to rIdx,
5131 pic16_allocProcessorRegister(): marks register wasUsed=0
5132 pic16_writeUsedRegs(): added a call to assign processor
5133 registers via pic16_assignFixedRegisters
5135 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5137 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5138 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5139 variables in unused register banks. Also the SSEG is placed
5140 wherever there is enough space for it, and IDATA can be anywhere
5141 in internal RAM. For now compile using -Wl-Y[stack_size].
5142 The mem file is different for this option as well, since it
5143 makes no sense of talking about DSEG lenght.
5145 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5147 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5148 in certain cases, e.g. when ROM assignment, patch provided
5149 from Albert den Haan.
5151 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6057 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6059 Fixed bug #621531 (const & volatile confusion in the type chain).
6060 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

6153 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6154 fetching of the pointer
6155 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6156 copied from genNearPointerSet()
6157 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6158 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
6159 If they pop r0/r1 they must be called in the opposite order than aopOp().
6160 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
6161 (resp. --stack-auto), prepared for --xstack

6172 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6174 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6175 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6176 type for bits was changed. It resulted in bit variables becoming
6177 global, which is not permitted in PIC 14 assembly output.
6179 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6181 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6192 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6194 A few small changes that speed up the peephole optimizer.
6198 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6200 Try to make the peephole optimizer smarter by maintaining
6201 an association between the assembly source code and the
6202 iCodes that originated them. Put this information to use
6203 with a new peephole rule condition "notVolatile" so that
6204 the rules can be aggressive yet still safe.
6209 * src/mcs51/peeph.def
6211 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6215 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6216 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6217 if the left or right operand symbols have the accuse flag set.
6219 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6221 Changed the type of the result of the ! (NOT) operator to char;
6222 previously it returned the same type as the source. This allows
6223 us to eliminate all the genFloatNot functions (all of its target
6224 implementations were very buggy) since !float can use the same
6227 * src/SDCCicode.c (ast2iCode): ! returns char
6228 * src/mcs51/gen.c (genNot, genNotFloat),
6229 * src/ds390/gen.c (genNot, genNotFloat),
6230 * src/z80/gen.c (genNot, genNotFloat),
6231 * src/pic/gen.c (genNot, genNotFloat),
6232 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
6234 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
6236 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6237 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6238 during interrupts. Ensure WSAVE is located at a shared bank address.
6239 2. Fixed page selection in some places
6240 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6241 the registers name strings.
6242 4. Fixed "signed / unsigned compare" compiler warnings.
6243 5. The PIC port manages its own allocation of the general purpose
6244 registers, but makes no attempt to reuse them. As a result when
6245 compiling it soon runs out of general purpose registers. Some
6246 additional code was added to the files pcode.c and device.c to walk
6247 through the function call tree and rename the registers so that they
6257 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6258 genPlus() & genMinus() when the result is the same as left or right
6260 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6264 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6266 Made bitfield a distinct type from bit so that bitfields
6267 convert as per ANSI C and bits retain their traditional
6268 boolean style behaviour. Implemented bitfield support in
6276 * src/ds390/gen.c: bit v bitfield split
6277 * src/z80/gen.c: New support for bitfields
6278 * support/regression/tests/bitfields.c: reenabled z80,
6281 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6283 Rules 246.x, 247.x relate to bitfields, the others speed up
6284 access to xdata mapped I/O devices.
6286 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6288 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6290 Cleaned up genPackBits and genUnpackBits and added two helper
6291 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6292 for literal assignments in genPackBits (thanks to Frieder for
6298 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6300 Fixed bug #748310 (pointer to function type mishandled when the
6301 function name is omitted). Also fixed a SIGSEGV when a function
6302 attribute (reentrant, etc) is used on a non-function or on a
6303 function but misplaced before the parameter list.
6305 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6307 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6308 * support/Util/SDCCerr.h,
6309 * support/Util/SDCCerr.c: Added func attr misuse error msg
6311 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
6313 Fixed bug #787649 by anonymous
6314 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

6330 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6332 Made the constant following the "interrupt" keyword optional. If
6333 omitted, the function will not automatically be given an entry
6334 in the interrupt vector table (similar to #pragma NOIV, but
6335 less syntacticly kludgy). The interrupt number is also now
6336 range checked. Also fixed a bug in the high order bit example

6350 * src/SDCCicode.c (operandOperation): rewritten some ops
6351 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6352 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6354 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6355 be re-activated by defining REDUCE_LITERALS)
6356 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6357 unsigned, but are signed by default
6358 * src/SDCCval.c (constVal): rearranged
6359 * src/SDCCval.c (valMod): preliminary fix
6360 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6402 constants are unsigned; added recognition of "u" flag for unsigned
6403 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
6404 * src/SDCCval.c (valDiv, valMod): fixed signdness
6405 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
6406 signedness of modulo, left and right shift

6866 added if/endif conditional macros to remove options help
6867 messages from optionsTable when a port is not configured, added
6868 support for the PIc16 port in the ports table, when executing
6869 the compiler with no port specified on command line, a default
6870 port is selected with the new macro DEFAULT_PORT which is
6871 defined in port.h, in setDefaultOptions() linkOptions is removed
6872 from initialization assignment, since now it is a set,
6873 parseCmdLine uses setParseWithComma for linkOptions, in
6874 linkEdit() linkOptions are accessed with new function indexSet()
6875 which returns the i'th item of a set variable. See SDCCset.c, in
6876 linkEdit() when calling buildCmdLine(), added linkOptions as
6877 last argument. Now users can pass arguments to gplink via the
6878 -Wl option, main() uses pic16glue() to glue up pic16 programs

6892 gpasm complaining and test the linkage with gplink, _linkCmd and
6893 _asmCmd changed to be more gplink and gpasm friendly
6894 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6895 produced an error when parsed, peep rule 12 is added to utilize
6896 movff, but it is commented out since the pCode does not support
6897 yet a command with 2 address arguments
6899 2003-05-18 <johan AT balder>
6901 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6928 2003-05-11 Borut Razem <borut.razem AT siol.net>
6930 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

7940 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7942 2003-01-04 <johan AT balder>
7944 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7946 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7947 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

7959 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7960 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7962 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7964 * in \sdcc\as\mcs51\ changed these files in order to create an
7965 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7966 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7967 following files to include the previous two files: aslink.dsp,
7968 Makefile.aslink, Makefile.bcc, and Makefile.in.
7970 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7971 .adb instead of .cdb
7973 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7975 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7976 value from option --iram-size.
7978 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7980 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7983 2002-09-18 <wiml AT hhhh.org>
7985 * SDCClrange.h: exposed setFromRange() and setToRange()
7986 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7987 packRegsForAccUse() (bug 542397)
7988 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7989 multiple times and emitting the fetch operations more than once
7990 added aopGetUsesAcc() function to allow binary operators to
7991 fetch their operands in the correct order; made genMinus() emit
7992 compact code for X = LITERAL - Y
7994 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7995 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7996 sprintf() in line 1267.
7998 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7999 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8002 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8003 Changes to aslink (All the changes are marked with 'JCF'):
8005 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8008 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8009 area BSEG. Also moves, if possible, the DATA area down into the internal
8010 ram so more space is available.
8012 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8015 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8016 not bytes. Function summary() which creates a memory usage summary
8017 file with extension .mem. Reports of overlaping stack and small stack
8018 size. If the space for the stack is less than 16 bytes aslink trows a
8021 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8022 the 8051. Option 'y' for memory summary output file.
8024 Changes to sdcc (All the changes are marked with 'JCF'):
8026 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8028 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8029 overlaying area for it (uses RegBankUsed[4]).
8031 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8032 bank zero as used by default. By default aslink locates the stack
8033 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8034 the creation of the .mem file. Delegates the allocation of data area
8035 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8036 the begining of the stack area to aslink.
8038 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8039 glue() in SDCCglue.c creates an area for it.
8041 2002-09-03 Borut Razem <borut.razem AT siol.net>
8042 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8043 sdcc/src/pic/glue.c:
8044 introduced atexit() handler for teporay files removal in case of
8045 errors, assertions, ...
8047 2002-08-29 Borut Razem <borut.razem AT siol.net>
8048 * sdcc/support/cpp2/auto-host_vc_in.h:
8049 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8050 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8051 Maybe there is a similar problem with BORLANDC? It should be checked!
8053 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8054 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8055 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8056 was not executed, and the compiler (cl) launched a warning:
8057 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8059 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8060 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8062 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8063 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8065 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8066 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8067 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8068 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8069 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8070 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8071 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8072 - added Release configuration in VS projects
8073 - review of compiler an linker options
8074 - VC .exe files are generated in bin_vc directory, not to interfere
8075 with binaries generated from other projects (cygwin, mingw, bcc ...)
8077 * sdcc/src/yacc.dsp: added
8079 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8080 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8081 and insert the version number definitions from .version
8083 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8085 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8086 added - genarate auto-host.h using auto-host_vc_in.h as template
8089 removed from CVS, generated automatically
8091 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8092 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8094 2002-08-11 Borut Razem <borut.razem AT siol.net>
8095 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8097 2002-08-10 Borut Razem <borut.razem AT siol.net>
8098 * src/SDCCmain.c (main):
8099 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8100 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8101 The consequence was that some temporary files were not removed.
8104 unification of code in functions tempfilename() and tempfile():
8105 function tempnam() is defined in Visual Studio 6.0 and .NET
8107 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8109 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8110 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8111 - removed compiler command line option /WX: Treats all warnings as errors
8112 - update a list of source files, included into the project
8114 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8115 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8116 changed project type to Generic Project so that can be correcly converted to VS.NET project
8118 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8120 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8122 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8124 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8125 added return 0 statements after assert() to make compiler happy
8127 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8128 added newline in the def file to keep MSC compiler satisfied
8130 * sdcc/src/z80/gen.c:
8131 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8132 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8133 - solved MSC error in function aopDump()
8135 * sdcc_vc.h: define PREFIX as "\\sdcc"
8137 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8138 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8140 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8141 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8142 - Rewrote the register banking algorithm.
8143 - Added pCode live-range analysis to registers (for now, only non-used and
8144 singly-used registers optimized away)
8146 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8148 * 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.

8177 2002-03-28 Johan Knol <johan AT balder>
8179 * src/SDCCval.c: fixed bug #532436
8181 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8183 Added "char *Processor" field to the port structure.
8186 Added -p option. Allows port dependent processor to be specified.
8189 Initialized the new field char *Processor field to NULL in all ports
8192 Compiler generated registers for interrupt context saving
8193 were not getting allocated.
8195 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8198 Fixed left shift. Will promote the left side of a left shift
8199 if a) left shifting more than size of operand or b) when assigned
8200 to something size > size of left side
8202 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8204 tons of changes. Register allocation has been
8205 rewritten. Added customization for the various PICs. Flow
8206 analysis is restructured. ...

8313 Previous fix was not good. basic blocks that have "break" or "return" are
8314 not really partof a loop , but live ranges used in these blocks should
8315 be live thru the entire loop, so set partOfLoop but don't add them to
8318 2002-02-21 <johan AT FRIJA>
8320 * src/SDCCcse.c: fixed bug #514308
8322 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
