2093 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2095 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2097 * device/lib/printf_large.c: removed inline assembly for portability and
2098 readability. Use printf_fast if speed or size are more important.
2099 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2100 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2102 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2104 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2105 prevent compiler warning
2107 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2109 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2110 moved to level 0 and declared as static. Also they are explicit
2111 placed in access bank. This was necessery because some times they
2112 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2113 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2114 optimizations. Currently only compare to unsigned char is implemented,
2115 * src/pic16/gen.c: added fReturnIdx array,
2116 * (struct resolvedIfx) is moved to gen.h and made public,
2117 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2118 * (aopForSym): added an optimization to directly store in stack of
2119 the operand of a SEND iCode,
2120 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2121 but as registers instead (AOP_REG) using the fReturnIdx array,
2122 * (pic16_freeAsmop): remove the freed register from the
2123 _G.sregsAlloc field,
2124 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2125 a compare of 'WREG',
2126 * (pic16_popGetTempRegCond): changed function prototype, now
2127 function takes also a bitVector argument v which holds the current
2128 set of registers that are allocated for stack access by aopForSym,
2129 registers allocated in aopForSym for accessing stack symbols are not
2130 any more part of the functions usedRegs field,
2131 * (genCall): some times aopOp is called for a stack variable to be
2132 send, aopForSym might perform the push, if this is true make sure
2133 that genCall doesn't push the variable twice by testing _G.resDirect,
2134 * (genFunction): changed testing for unspecified interrupt number
2135 from 256 to INTNO_UNSPEC,
2136 * modified selection scheme of frame pointer generation. Previously
2137 if function did use local registers a frame pointer was generated,
2138 now a frame pointer is generated only if function has arguments
2139 (that need PLUSW2 register access), or has stack arguments, or the
2140 compiler is not instructed to omit the frame pointer,
2141 * (genEndFunction): before restoring local registers that were saved
2142 in the function preamble, also restore the registers that *might*
2143 have been allocated for stack access,
2144 * (genRet): removed some old comments,
2145 * (genCmp, the active (RN's) version): added a call to the
2146 pic16_genCmp_special function to perform the compare with a more
2147 robust and optimized way,
2148 * (genInline): a feature has been added in inline code generation,
2149 which allows a wildcard variable substitution when writing inline
2150 assembly. Code is incomplete and experimental therefore undocumented,
2151 * (genCast): changed order of aopOp for result and right to allow

2821 Adding support for replacing ljmps with sjmps in jumptables
2822 generated for switch statements. For now you need to set the
2823 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2824 Now 4 algorithms for mcs51 jumptable generation are used:
2825 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2826 addresses loaded pc-relative for up to 112 cases and stack-pushing
2827 target addresses loaded with offset from dptr for up to 256 cases.

2857 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2859 * added libc directory. The current version of LibC contains string
2860 functions, ctype functions and macros and some functions of the
2861 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2862 be extensively tested in the future. Standard disclaimer here.
2863 Library is not automatically build yet. But one can build it by
2864 invoking 'make' inside the libc directory.

2875 * (pic16_storeForReturn): optimized return of 0,
2876 * (genCmp): experimental code for new genCmp which uses PIC18's
2877 special compare&skip instructions. Initial tests fail some times
2878 with variables grater than 1 byte in size, so new code is disabled,
2879 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2881 * (genCast): began a fix to optimize the casting of a bit to another
2882 bit, now assigning a bitfield to another bitfield will fail, sorry,

2891 and 1 for banking instruction,
2892 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2893 caused stop processing pCodes after a inline assembly block,
2894 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2896 registers when it shouldn't,
2897 * src/pic16/ralloc.c (allocReg): add preliminary support for
2898 supporting a limited set of temporary registers,
2900 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5908 loaded with the linker search paths (-L arguments) and the libraries
5909 to be linked with the current source (-l arguments). Changes
5910 currently will affect only the pic16 port.
5911 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5912 include path the port specific paths and port specific libraries,
5913 * gplink command now contains the $3 argument,
5914 * src/pic16/device.h,

5931 Documenting changes from previous commits.
5932 * configure.in (version 1.56),
5933 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5934 when generating output files to configure the pic16 library,
5935 but now I've commented it out, since gputils aren't installed in the
5936 SF compile farm, so library won't compile
5938 * device/lib/Makefile.in (version 1.56): initially I've added in
5939 target 'all' the prerequestive 'model-pic16' so it compiled the
5940 pic16 library, but now I've commented it out for the same reasons
5942 * added targets 'model-pic16' and 'objects-pic16' to compile the
5944 * added target 'port-specific-objects-pic16' to handle the
5945 generated libraries and copy them into the build/ directory
5946 * added target 'clean-intermediate-pic16' to clean intermediate
5947 files into pic16 directory
5948 * in target 'installdirs' added line to create directory pic16 in

6193 * src/SDCCast.c (decorateType),
6194 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
6195 LEFT_OP (left shift)
6197 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6199 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6200 (default behaviour).
6202 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6204 A python script to validate compiler diagnostic messages. It can be
6205 used to verify that sdcc complains about bad c source code and
6206 gives a good location of the error.
6207 * support/valdiag/Makefile,
6208 * support/valdiag/valdiag.py,
6209 * support/valdiag/tests/*
6211 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6226 Bug reported from Jesus Calvino-Fraga
6228 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6230 * sdcc.spec: updated
6231 * device/include/Makefile.in: don't install CVS directories
6232 * device/lib/Makefile.in: added removal of CVS directories after install
6233 * doc/Makefile: fixed install, added local_icons
6234 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6235 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6236 * src/ds390/gen.c (genRightShift): fixed bug #870788

6239 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6241 PIC16 port related changes:
6242 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6243 added variable stackPos,
6245 * gen.c: genCall, assignResultValue: added support for
6246 pushing/retrieving function parameters to/from stack,
6247 genFunction,genEndFunction: setup stack frame for the
6249 genAddrOf: will be changed according to bug 863624
6251 * added files genutils.c and genutils.h which contain gen*
6252 debugged and optimised functions extracted from gen.c
6254 * glue.c: added variable 'externs' which holds extern symbols,
6255 pic16emitRegularMap: is modified to properly handle relocatable
6256 symbols under the new scheme,
6257 pic16createInterruptVect: is modified
6258 pic16printPublics: is modified to emit 'global' assembler directives,
6259 added pic16_printExterns to print extern symbols,
6260 pic16glue: initializes stack/frame pointer in the beginning of
6261 the assembly output. Temporary hack, will be corrected later,
6262 because gplink yet does not support stack and SDCC does not
6263 yet support a type of crt0.o object to create the final binary.
6265 * Removed many lines that contain 8051 legacy code.
6266 * The code is finally placed under a 'code' directive.
6267 * Added port specific options.
6269 * _process_pragma: simplified since now we do not need *special*
6270 include file to define SFR registers. But a separate header
6271 will be needed. This will be developed later.
6272 * _pic16_parseOptions: added, parses port specific options:
6273 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6274 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6275 --preplace-udata-with=
6277 * _pic16_setDefaultOptions: modified to initialize section names,
6278 but hack is temporarly out of order since it needs improvement.
6279 * _pic16_genAssemblerPreamble: configuration words are emitted by
6280 their address instead of their name. This part is incomplete and
6281 supports only the 18Fxx2 devices. Other devices will emit an error
6282 during assembly since they do not contain the same set of config
6284 * _pic16_genIVT: is modified,
6286 * pcode.c: added definitions for some hardware registers that are needed
6288 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6289 All PCI entries are updated. Now LFSR is supported.
6290 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6291 * added pic16_newpCodeOpLit2 to support instructions with
6292 two literal arguments
6293 * pic16_pCode2str: corrected code that emits assembler instructions
6294 with two literal operands and those that have an access bit modifier
6295 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6296 this fixes a bug which caused some labels to be lost, when an
6297 assembler directive was added, i.e. banksel,
6298 * pic16_FixRegisterBanking: improved logic that causes the insertion
6300 * InlineFunction: functions that are called once, are not any more
6301 inlined. This can be a port option in the future,
6303 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6305 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6306 hold the corresponding uninitialized symbols,
6307 * pic16_allocProcessorRegister: registers have explicit marked the
6309 * pic16_allocInternalRegister: registers are explicit marked as
6311 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6312 processing list, so bit registers were lost,
6315 * ralloc.h: added field 'accessBank' and original symbol operand
6316 in register definition,
6317 * removed the field isMapped from register definition,
6319 ** Several functions have been removed from various sources:
6320 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6321 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6322 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6323 pic16_assignRelocatableRegisters
6325 ** others have been introduced:
6326 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6327 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6329 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6331 * support/scripts/inc2h.pl: changed definition of BIT_AT
6332 to emit 'sbit at' instead of 'bit at'. This was a request.
6334 PIC16 port related preliminary changes:
6335 * gen.c: prefixed function popRegFromString with
6336 pic16_ and all references to it corrected
6337 * pcode.c: all pic16_pc_* hardware registers prefixed
6338 with underscore (_),
6339 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6340 * ralloc.c: newReg(): when register is REG_SFR then
6341 set address to rIdx,
6342 pic16_allocProcessorRegister(): marks register wasUsed=0
6343 pic16_writeUsedRegs(): added a call to assign processor
6344 registers via pic16_assignFixedRegisters
6346 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6348 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6349 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6350 variables in unused register banks. Also the SSEG is placed
6351 wherever there is enough space for it, and IDATA can be anywhere
6352 in internal RAM. For now compile using -Wl-Y[stack_size].
6353 The mem file is different for this option as well, since it
6354 makes no sense of talking about DSEG lenght.
6356 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6358 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6359 in certain cases, e.g. when ROM assignment, patch provided
6360 from Albert den Haan.
6362 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6601 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6603 * src/SDCCast.c (decorateType): disabled a transformation I added in
6604 revision 1.188 (access to fields of a structure at an absolute address);
6605 it breaks with bitfields, extern declarations, and gcse analysis.
6606 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6607 could be assigned through a pointer, so don't complain.
6608 * src/SDCCast.c (astErrors),
6610 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
6612 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

7363 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7364 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7365 fetching of the pointer
7366 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7367 copied from genNearPointerSet()
7368 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7369 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7370 If they pop r0/r1 they must be called in the opposite order than aopOp().
7371 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7372 (resp. --stack-auto), prepared for --xstack

7383 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7385 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7386 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7387 type for bits was changed. It resulted in bit variables becoming
7388 global, which is not permitted in PIC 14 assembly output.
7390 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7392 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7405 A few small changes that speed up the peephole optimizer.
7409 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7411 Try to make the peephole optimizer smarter by maintaining
7412 an association between the assembly source code and the
7413 iCodes that originated them. Put this information to use
7414 with a new peephole rule condition "notVolatile" so that
7415 the rules can be aggressive yet still safe.
7420 * src/mcs51/peeph.def
7422 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7426 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7427 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7428 if the left or right operand symbols have the accuse flag set.
7430 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7432 Changed the type of the result of the ! (NOT) operator to char;
7433 previously it returned the same type as the source. This allows
7434 us to eliminate all the genFloatNot functions (all of its target
7435 implementations were very buggy) since !float can use the same
7438 * src/SDCCicode.c (ast2iCode): ! returns char

7447 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7448 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7449 during interrupts. Ensure WSAVE is located at a shared bank address.
7450 2. Fixed page selection in some places
7451 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7452 the registers name strings.
7453 4. Fixed "signed / unsigned compare" compiler warnings.
7454 5. The PIC port manages its own allocation of the general purpose
7455 registers, but makes no attempt to reuse them. As a result when
7456 compiling it soon runs out of general purpose registers. Some
7457 additional code was added to the files pcode.c and device.c to walk
7458 through the function call tree and rename the registers so that they
7468 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7469 genPlus() & genMinus() when the result is the same as left or right

7475 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7477 Made bitfield a distinct type from bit so that bitfields
7478 convert as per ANSI C and bits retain their traditional
7479 boolean style behaviour. Implemented bitfield support in
7487 * src/ds390/gen.c: bit v bitfield split
7488 * src/z80/gen.c: New support for bitfields
7489 * support/regression/tests/bitfields.c: reenabled z80,
7492 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7494 Rules 246.x, 247.x relate to bitfields, the others speed up
7495 access to xdata mapped I/O devices.
7497 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7499 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7501 Cleaned up genPackBits and genUnpackBits and added two helper
7502 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7503 for literal assignments in genPackBits (thanks to Frieder for
7509 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7511 Fixed bug #748310 (pointer to function type mishandled when the
7512 function name is omitted). Also fixed a SIGSEGV when a function
7513 attribute (reentrant, etc) is used on a non-function or on a
7514 function but misplaced before the parameter list.
7516 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7518 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7519 * support/Util/SDCCerr.h,

7541 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7543 Made the constant following the "interrupt" keyword optional. If
7544 omitted, the function will not automatically be given an entry
7545 in the interrupt vector table (similar to #pragma NOIV, but
7546 less syntacticly kludgy). The interrupt number is also now
7547 range checked. Also fixed a bug in the high order bit example

7563 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7565 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7566 be re-activated by defining REDUCE_LITERALS)

8077 added if/endif conditional macros to remove options help
8078 messages from optionsTable when a port is not configured, added
8079 support for the PIc16 port in the ports table, when executing
8080 the compiler with no port specified on command line, a default
8081 port is selected with the new macro DEFAULT_PORT which is
8082 defined in port.h, in setDefaultOptions() linkOptions is removed
8083 from initialization assignment, since now it is a set,
8084 parseCmdLine uses setParseWithComma for linkOptions, in
8085 linkEdit() linkOptions are accessed with new function indexSet()
8086 which returns the i'th item of a set variable. See SDCCset.c, in
8087 linkEdit() when calling buildCmdLine(), added linkOptions as
8088 last argument. Now users can pass arguments to gplink via the
8089 -Wl option, main() uses pic16glue() to glue up pic16 programs

8103 gpasm complaining and test the linkage with gplink, _linkCmd and
8104 _asmCmd changed to be more gplink and gpasm friendly
8105 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8106 produced an error when parsed, peep rule 12 is added to utilize
8107 movff, but it is commented out since the pCode does not support
8108 yet a command with 2 address arguments
8110 2003-05-18 <johan AT balder>
8112 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9145 2003-01-06 <johan AT balder>
9147 * src/SDCCicode.c: fixed array add
9149 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9150 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9151 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9153 2003-01-04 <johan AT balder>
9155 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9157 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9158 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9160 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

9170 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9171 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9173 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9175 * in \sdcc\as\mcs51\ changed these files in order to create an
9176 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9177 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9178 following files to include the previous two files: aslink.dsp,
9179 Makefile.aslink, Makefile.bcc, and Makefile.in.
9181 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9182 .adb instead of .cdb
9184 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9186 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9187 value from option --iram-size.
9189 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9191 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9194 2002-09-18 <wiml AT hhhh.org>
9196 * SDCClrange.h: exposed setFromRange() and setToRange()
9197 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9198 packRegsForAccUse() (bug 542397)
9199 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9200 multiple times and emitting the fetch operations more than once
9201 added aopGetUsesAcc() function to allow binary operators to
9202 fetch their operands in the correct order; made genMinus() emit
9203 compact code for X = LITERAL - Y
9205 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9206 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9207 sprintf() in line 1267.
9209 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9210 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9213 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9214 Changes to aslink (All the changes are marked with 'JCF'):
9216 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9219 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9220 area BSEG. Also moves, if possible, the DATA area down into the internal
9221 ram so more space is available.
9223 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9226 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9227 not bytes. Function summary() which creates a memory usage summary
9228 file with extension .mem. Reports of overlaping stack and small stack
9229 size. If the space for the stack is less than 16 bytes aslink trows a
9232 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9233 the 8051. Option 'y' for memory summary output file.
9235 Changes to sdcc (All the changes are marked with 'JCF'):
9237 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9239 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9240 overlaying area for it (uses RegBankUsed[4]).
9242 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9243 bank zero as used by default. By default aslink locates the stack
9244 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9245 the creation of the .mem file. Delegates the allocation of data area
9246 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9247 the begining of the stack area to aslink.
9249 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9250 glue() in SDCCglue.c creates an area for it.
9252 2002-09-03 Borut Razem <borut.razem AT siol.net>
9253 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9254 sdcc/src/pic/glue.c:
9255 introduced atexit() handler for teporay files removal in case of
9256 errors, assertions, ...
9258 2002-08-29 Borut Razem <borut.razem AT siol.net>
9259 * sdcc/support/cpp2/auto-host_vc_in.h:
9260 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9261 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9262 Maybe there is a similar problem with BORLANDC? It should be checked!
9264 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9265 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9266 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9267 was not executed, and the compiler (cl) launched a warning:
9268 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9270 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9271 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9273 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9274 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9276 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9277 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9278 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9279 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9280 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9281 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9282 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9283 - added Release configuration in VS projects
9284 - review of compiler an linker options
9285 - VC .exe files are generated in bin_vc directory, not to interfere
9286 with binaries generated from other projects (cygwin, mingw, bcc ...)
9288 * sdcc/src/yacc.dsp: added
9290 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9291 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9292 and insert the version number definitions from .version
9294 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9296 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9297 added - genarate auto-host.h using auto-host_vc_in.h as template
9300 removed from CVS, generated automatically
9302 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9303 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9305 2002-08-11 Borut Razem <borut.razem AT siol.net>
9306 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9308 2002-08-10 Borut Razem <borut.razem AT siol.net>
9309 * src/SDCCmain.c (main):
9310 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9311 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9312 The consequence was that some temporary files were not removed.
9315 unification of code in functions tempfilename() and tempfile():
9316 function tempnam() is defined in Visual Studio 6.0 and .NET
9318 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9320 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9321 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9322 - removed compiler command line option /WX: Treats all warnings as errors
9323 - update a list of source files, included into the project
9325 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9326 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9327 changed project type to Generic Project so that can be correcly converted to VS.NET project
9329 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9331 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9333 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9335 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9336 added return 0 statements after assert() to make compiler happy
9338 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9339 added newline in the def file to keep MSC compiler satisfied
9341 * sdcc/src/z80/gen.c:
9342 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9343 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9344 - solved MSC error in function aopDump()
9346 * sdcc_vc.h: define PREFIX as "\\sdcc"
9348 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9349 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9351 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9352 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9353 - Rewrote the register banking algorithm.
9354 - Added pCode live-range analysis to registers (for now, only non-used and
9355 singly-used registers optimized away)
9357 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9359 * 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.

9386 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9388 2002-03-28 Johan Knol <johan AT balder>
9390 * src/SDCCval.c: fixed bug #532436
9392 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9394 Added "char *Processor" field to the port structure.
9397 Added -p option. Allows port dependent processor to be specified.
9400 Initialized the new field char *Processor field to NULL in all ports
9403 Compiler generated registers for interrupt context saving
9404 were not getting allocated.
9406 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9409 Fixed left shift. Will promote the left side of a left shift
9410 if a) left shifting more than size of operand or b) when assigned
9411 to something size > size of left side
9413 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9415 tons of changes. Register allocation has been
9416 rewritten. Added customization for the various PICs. Flow
9417 analysis is restructured. ...
9423 Added. device.c is a PIC port hack to accomodate variations
9426 2002-03-13 Michael Hope <michaelh AT vroom>
9428 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9430 2002-03-04 johanknol <johanknol AT manik>
9432 * /src/SDCCval.c: fixed
9434 const unsigned char arr[][2] = { { 0, 1 } };

9437 2002-03-04 bela <bela AT manik>
9439 * /device/include/mcs51reg.h:
9440 ds89c420 register definition update

9521 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9523 * sdcc/src/SDCCloop.c:
9524 Previous fix was not good. basic blocks that have "break" or "return" are
9525 not really partof a loop , but live ranges used in these blocks should
9526 be live thru the entire loop, so set partOfLoop but don't add them to
9529 2002-02-21 <johan AT FRIJA>
9531 * src/SDCCcse.c: fixed bug #514308
9533 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9536 Fixed BUG #519583. If a conditional block ended in a return/break
9537 statement inside a loop, it was not being considered part of the loop.
9539 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9541 2002-02-10 Karl Bongers <karl AT turbobit.com>
9544 Fixed up SDCDB debugger somewhat. Updated debugger/README
9545 with lots of comments and notes.
9547 * device/examples/test2.c:
9548 Fix bug, "red" variable not being initialized(compiler complained).
9550 * device/examples/Makefile, examples/test3.c:
9551 Add Makefile in device/examples folder, compiles test3.c
9552 for use as a multiple module SDCDB test case.
9554 * sim/ucsim/cmd.src/cmdset.cc:
9555 Took out debug printfs in ucsim "next" command.
9558 Karl and Johan start ucsim XA support. Most dissassembly working,
9559 about 75% emulation done(plenty of work remaining).
9561 * sim/ucsim/z80.src:
9562 Add Z80 support to ucsim, add test-ucz80 regression test,
9563 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
9564 Notice z80 compiler fails on examples/test3.c/crc code.
9566 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
