1920 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1921 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1922 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1923 always available in leading double underscore form. The C99 support is

2004 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2006 * device/lib/printf_large.c: removed inline assembly for portability and
2007 readability. Use printf_fast if speed or size are more important.
2008 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2009 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2011 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2013 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2014 prevent compiler warning
2016 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2018 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2019 moved to level 0 and declared as static. Also they are explicit
2020 placed in access bank. This was necessery because some times they
2021 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2022 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2023 optimizations. Currently only compare to unsigned char is implemented,
2024 * src/pic16/gen.c: added fReturnIdx array,
2025 * (struct resolvedIfx) is moved to gen.h and made public,
2026 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2027 * (aopForSym): added an optimization to directly store in stack of
2028 the operand of a SEND iCode,
2029 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2030 but as registers instead (AOP_REG) using the fReturnIdx array,
2031 * (pic16_freeAsmop): remove the freed register from the
2032 _G.sregsAlloc field,
2033 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2034 a compare of 'WREG',
2035 * (pic16_popGetTempRegCond): changed function prototype, now
2036 function takes also a bitVector argument v which holds the current
2037 set of registers that are allocated for stack access by aopForSym,
2038 registers allocated in aopForSym for accessing stack symbols are not
2039 any more part of the functions usedRegs field,
2040 * (genCall): some times aopOp is called for a stack variable to be
2041 send, aopForSym might perform the push, if this is true make sure
2042 that genCall doesn't push the variable twice by testing _G.resDirect,
2043 * (genFunction): changed testing for unspecified interrupt number
2044 from 256 to INTNO_UNSPEC,
2045 * modified selection scheme of frame pointer generation. Previously
2046 if function did use local registers a frame pointer was generated,
2047 now a frame pointer is generated only if function has arguments
2048 (that need PLUSW2 register access), or has stack arguments, or the
2049 compiler is not instructed to omit the frame pointer,
2050 * (genEndFunction): before restoring local registers that were saved
2051 in the function preamble, also restore the registers that *might*
2052 have been allocated for stack access,
2053 * (genRet): removed some old comments,
2054 * (genCmp, the active (RN's) version): added a call to the
2055 pic16_genCmp_special function to perform the compare with a more
2056 robust and optimized way,
2057 * (genInline): a feature has been added in inline code generation,
2058 which allows a wildcard variable substitution when writing inline
2059 assembly. Code is incomplete and experimental therefore undocumented,
2060 * (genCast): changed order of aopOp for result and right to allow
2061 aopForSym to directly load the result if possible,
2062 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2063 perform an optimized compare on some selected special occasions,
2064 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2065 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2066 generate an IVT any more,
2067 * src/pic16/main.c (pic16_optionsTable): added command line option
2069 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2070 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2072 * src/pic16/NOTES: Raphael Neider added in list of active developers
2073 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2074 jumptable_end to prevent bug #,
2075 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2076 inCond and outCond fields,
2077 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2078 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2079 turn off register spilling,
2080 * (packRegsForOneUse): synced with other ports' versions although it
2081 is not used currently,
2082 * (pic16_packRegisters): added an optimization while reading
2083 structure bitfields, some registers may be saved (malloc code is
2084 decreased by 80 bytes)
2086 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2088 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2089 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2090 this can be optimized more?
2092 2005-03-10 Raphael Neider <rneider AT web.de>
2094 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2095 genNearPointerGet): (hopefully) fixed access to bitfields via
2096 pointers (p->bitN = x; and x = p->bitN; failed)
2098 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2142 to keep the correct label reference count when adding/removing references
2143 to labels. A peephole file using this is appended to patch #1144962.

2730 Adding support for replacing ljmps with sjmps in jumptables
2731 generated for switch statements. For now you need to set the
2732 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2733 Now 4 algorithms for mcs51 jumptable generation are used:
2734 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2735 addresses loaded pc-relative for up to 112 cases and stack-pushing
2736 target addresses loaded with offset from dptr for up to 256 cases.

2766 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2768 * added libc directory. The current version of LibC contains string
2769 functions, ctype functions and macros and some functions of the
2770 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2771 be extensively tested in the future. Standard disclaimer here.
2772 Library is not automatically build yet. But one can build it by
2773 invoking 'make' inside the libc directory.

2784 * (pic16_storeForReturn): optimized return of 0,
2785 * (genCmp): experimental code for new genCmp which uses PIC18's
2786 special compare&skip instructions. Initial tests fail some times
2787 with variables grater than 1 byte in size, so new code is disabled,
2788 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2790 * (genCast): began a fix to optimize the casting of a bit to another
2791 bit, now assigning a bitfield to another bitfield will fail, sorry,
2792 * src/pic16/main.c: disabled the use of lr-support feature,
2793 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2800 and 1 for banking instruction,
2801 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2802 caused stop processing pCodes after a inline assembly block,
2803 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2805 registers when it shouldn't,
2806 * src/pic16/ralloc.c (allocReg): add preliminary support for
2807 supporting a limited set of temporary registers,
2809 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2811 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

2815 (genFunction): optimize RECEIVE iCodes in reentrant functions
2817 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5814 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5816 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5817 loaded with the linker search paths (-L arguments) and the libraries
5818 to be linked with the current source (-l arguments). Changes
5819 currently will affect only the pic16 port.
5820 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5821 include path the port specific paths and port specific libraries,
5822 * gplink command now contains the $3 argument,
5823 * src/pic16/device.h,
5824 * src/pic16/device.c,: structure PIC_device is made public and
5825 renamed to PIC16_device, the same for variable Pics which is renamed

5840 Documenting changes from previous commits.
5841 * configure.in (version 1.56),
5842 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5843 when generating output files to configure the pic16 library,
5844 but now I've commented it out, since gputils aren't installed in the
5845 SF compile farm, so library won't compile
5847 * device/lib/Makefile.in (version 1.56): initially I've added in
5848 target 'all' the prerequestive 'model-pic16' so it compiled the
5849 pic16 library, but now I've commented it out for the same reasons
5851 * added targets 'model-pic16' and 'objects-pic16' to compile the
5853 * added target 'port-specific-objects-pic16' to handle the
5854 generated libraries and copy them into the build/ directory
5855 * added target 'clean-intermediate-pic16' to clean intermediate
5856 files into pic16 directory
5857 * in target 'installdirs' added line to create directory pic16 in

6170 the assembly output. Temporary hack, will be corrected later,
6171 because gplink yet does not support stack and SDCC does not
6172 yet support a type of crt0.o object to create the final binary.
6174 * Removed many lines that contain 8051 legacy code.
6175 * The code is finally placed under a 'code' directive.
6176 * Added port specific options.
6178 * _process_pragma: simplified since now we do not need *special*
6179 include file to define SFR registers. But a separate header
6180 will be needed. This will be developed later.
6181 * _pic16_parseOptions: added, parses port specific options:
6182 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6183 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6184 --preplace-udata-with=
6186 * _pic16_setDefaultOptions: modified to initialize section names,
6187 but hack is temporarly out of order since it needs improvement.
6188 * _pic16_genAssemblerPreamble: configuration words are emitted by
6189 their address instead of their name. This part is incomplete and
6190 supports only the 18Fxx2 devices. Other devices will emit an error
6191 during assembly since they do not contain the same set of config
6193 * _pic16_genIVT: is modified,
6195 * pcode.c: added definitions for some hardware registers that are needed
6197 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6198 All PCI entries are updated. Now LFSR is supported.
6199 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6200 * added pic16_newpCodeOpLit2 to support instructions with
6201 two literal arguments
6202 * pic16_pCode2str: corrected code that emits assembler instructions
6203 with two literal operands and those that have an access bit modifier
6204 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6205 this fixes a bug which caused some labels to be lost, when an
6206 assembler directive was added, i.e. banksel,
6207 * pic16_FixRegisterBanking: improved logic that causes the insertion
6209 * InlineFunction: functions that are called once, are not any more
6210 inlined. This can be a port option in the future,
6212 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6214 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6215 hold the corresponding uninitialized symbols,
6216 * pic16_allocProcessorRegister: registers have explicit marked the
6218 * pic16_allocInternalRegister: registers are explicit marked as
6220 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6221 processing list, so bit registers were lost,
6224 * ralloc.h: added field 'accessBank' and original symbol operand
6225 in register definition,
6226 * removed the field isMapped from register definition,
6228 ** Several functions have been removed from various sources:
6229 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6230 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6231 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6232 pic16_assignRelocatableRegisters
6234 ** others have been introduced:
6235 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6236 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6238 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6240 * support/scripts/inc2h.pl: changed definition of BIT_AT
6241 to emit 'sbit at' instead of 'bit at'. This was a request.
6243 PIC16 port related preliminary changes:
6244 * gen.c: prefixed function popRegFromString with
6245 pic16_ and all references to it corrected
6246 * pcode.c: all pic16_pc_* hardware registers prefixed
6247 with underscore (_),
6248 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6249 * ralloc.c: newReg(): when register is REG_SFR then
6250 set address to rIdx,
6251 pic16_allocProcessorRegister(): marks register wasUsed=0
6252 pic16_writeUsedRegs(): added a call to assign processor
6253 registers via pic16_assignFixedRegisters
6255 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6257 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6258 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6259 variables in unused register banks. Also the SSEG is placed
6260 wherever there is enough space for it, and IDATA can be anywhere
6261 in internal RAM. For now compile using -Wl-Y[stack_size].
6262 The mem file is different for this option as well, since it
6263 makes no sense of talking about DSEG lenght.
6265 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6267 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6268 in certain cases, e.g. when ROM assignment, patch provided
6269 from Albert den Haan.

6510 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6512 * src/SDCCast.c (decorateType): disabled a transformation I added in
6513 revision 1.188 (access to fields of a structure at an absolute address);
6514 it breaks with bitfields, extern declarations, and gcse analysis.
6515 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6516 could be assigned through a pointer, so don't complain.
6517 * src/SDCCast.c (astErrors),
6519 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

6621 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
6622 uninitialized variables) for the mcs51. Set environment variable
6623 SDCC_GENRAMCLEAR to test.
6624 xdata initialization slightly shorter
6626 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7157 support for standard C idiom of memory mapped variables; for
7158 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7159 to xdata int at 0x1234 tempvar = 1.

7273 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7274 fetching of the pointer
7275 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7276 copied from genNearPointerSet()
7277 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7278 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7294 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7295 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7296 type for bits was changed. It resulted in bit variables becoming
7297 global, which is not permitted in PIC 14 assembly output.
7299 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7301 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7314 A few small changes that speed up the peephole optimizer.
7318 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7320 Try to make the peephole optimizer smarter by maintaining
7321 an association between the assembly source code and the
7322 iCodes that originated them. Put this information to use
7323 with a new peephole rule condition "notVolatile" so that
7324 the rules can be aggressive yet still safe.
7329 * src/mcs51/peeph.def
7331 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7335 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7336 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7337 if the left or right operand symbols have the accuse flag set.
7339 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7341 Changed the type of the result of the ! (NOT) operator to char;
7342 previously it returned the same type as the source. This allows
7343 us to eliminate all the genFloatNot functions (all of its target
7344 implementations were very buggy) since !float can use the same
7347 * src/SDCCicode.c (ast2iCode): ! returns char

7356 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7357 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7358 during interrupts. Ensure WSAVE is located at a shared bank address.
7359 2. Fixed page selection in some places
7360 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7361 the registers name strings.
7362 4. Fixed "signed / unsigned compare" compiler warnings.
7363 5. The PIC port manages its own allocation of the general purpose
7364 registers, but makes no attempt to reuse them. As a result when
7365 compiling it soon runs out of general purpose registers. Some
7366 additional code was added to the files pcode.c and device.c to walk
7367 through the function call tree and rename the registers so that they
7377 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7384 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7386 Made bitfield a distinct type from bit so that bitfields
7387 convert as per ANSI C and bits retain their traditional
7388 boolean style behaviour. Implemented bitfield support in
7396 * src/ds390/gen.c: bit v bitfield split
7397 * src/z80/gen.c: New support for bitfields
7398 * support/regression/tests/bitfields.c: reenabled z80,
7401 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7403 Rules 246.x, 247.x relate to bitfields, the others speed up
7404 access to xdata mapped I/O devices.
7406 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7408 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7410 Cleaned up genPackBits and genUnpackBits and added two helper
7411 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7412 for literal assignments in genPackBits (thanks to Frieder for
7418 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7420 Fixed bug #748310 (pointer to function type mishandled when the
7421 function name is omitted). Also fixed a SIGSEGV when a function
7422 attribute (reentrant, etc) is used on a non-function or on a
7423 function but misplaced before the parameter list.
7425 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7427 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7428 * support/Util/SDCCerr.h,
7429 * support/Util/SDCCerr.c: Added func attr misuse error msg

7450 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7452 Made the constant following the "interrupt" keyword optional. If
7453 omitted, the function will not automatically be given an entry
7454 in the interrupt vector table (similar to #pragma NOIV, but
7455 less syntacticly kludgy). The interrupt number is also now
7456 range checked. Also fixed a bug in the high order bit example

7470 * src/SDCCicode.c (operandOperation): rewritten some ops
7471 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7472 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7474 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7475 be re-activated by defining REDUCE_LITERALS)
7476 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7477 unsigned, but are signed by default
7478 * src/SDCCval.c (constVal): rearranged
7479 * src/SDCCval.c (valMod): preliminary fix
7480 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7522 constants are unsigned; added recognition of "u" flag for unsigned
7523 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7524 * src/SDCCval.c (valDiv, valMod): fixed signdness
7525 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7526 signedness of modulo, left and right shift

7985 * src/SDCCmain.c: linkOptions is changed to set *,
7986 added if/endif conditional macros to remove options help
7987 messages from optionsTable when a port is not configured, added
7988 support for the PIc16 port in the ports table, when executing
7989 the compiler with no port specified on command line, a default
7990 port is selected with the new macro DEFAULT_PORT which is
7991 defined in port.h, in setDefaultOptions() linkOptions is removed
7992 from initialization assignment, since now it is a set,
7993 parseCmdLine uses setParseWithComma for linkOptions, in
7994 linkEdit() linkOptions are accessed with new function indexSet()
7995 which returns the i'th item of a set variable. See SDCCset.c, in
7996 linkEdit() when calling buildCmdLine(), added linkOptions as
7997 last argument. Now users can pass arguments to gplink via the
7998 -Wl option, main() uses pic16glue() to glue up pic16 programs

8010 * src/pic16/glue.c: commented out some error producing lines
8011 * src/pic16/main.c: __config directives are commented out to stop
8012 gpasm complaining and test the linkage with gplink, _linkCmd and
8013 _asmCmd changed to be more gplink and gpasm friendly
8014 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8015 produced an error when parsed, peep rule 12 is added to utilize
8016 movff, but it is commented out since the pCode does not support
8017 yet a command with 2 address arguments
8019 2003-05-18 <johan AT balder>
8021 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8046 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8048 2003-05-11 Borut Razem <borut.razem AT siol.net>
8050 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8051 the path of bin directory, so that PATH is the only env. variable, which has to be set
8052 in case of standard installation.
8053 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9087 following files to include the previous two files: aslink.dsp,
9088 Makefile.aslink, Makefile.bcc, and Makefile.in.
9090 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9091 .adb instead of .cdb
9093 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9095 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9096 value from option --iram-size.
9098 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9100 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9103 2002-09-18 <wiml AT hhhh.org>
9105 * SDCClrange.h: exposed setFromRange() and setToRange()
9106 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9107 packRegsForAccUse() (bug 542397)
9108 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9109 multiple times and emitting the fetch operations more than once
9110 added aopGetUsesAcc() function to allow binary operators to
9111 fetch their operands in the correct order; made genMinus() emit
9112 compact code for X = LITERAL - Y
9114 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9115 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9116 sprintf() in line 1267.
9118 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9119 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9122 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9123 Changes to aslink (All the changes are marked with 'JCF'):
9125 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9128 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9129 area BSEG. Also moves, if possible, the DATA area down into the internal
9130 ram so more space is available.
9132 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9135 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9136 not bytes. Function summary() which creates a memory usage summary
9137 file with extension .mem. Reports of overlaping stack and small stack
9138 size. If the space for the stack is less than 16 bytes aslink trows a
9141 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9142 the 8051. Option 'y' for memory summary output file.
9144 Changes to sdcc (All the changes are marked with 'JCF'):
9146 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9148 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9149 overlaying area for it (uses RegBankUsed[4]).
9151 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9152 bank zero as used by default. By default aslink locates the stack
9153 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9154 the creation of the .mem file. Delegates the allocation of data area
9155 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9156 the begining of the stack area to aslink.
9158 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9159 glue() in SDCCglue.c creates an area for it.
9161 2002-09-03 Borut Razem <borut.razem AT siol.net>
9162 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9163 sdcc/src/pic/glue.c:
9164 introduced atexit() handler for teporay files removal in case of
9165 errors, assertions, ...
9167 2002-08-29 Borut Razem <borut.razem AT siol.net>
9168 * sdcc/support/cpp2/auto-host_vc_in.h:
9169 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9170 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9171 Maybe there is a similar problem with BORLANDC? It should be checked!
9173 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9174 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9175 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9176 was not executed, and the compiler (cl) launched a warning:
9177 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9179 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9180 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9182 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9183 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9185 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9186 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9187 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9188 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9189 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9190 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9191 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9192 - added Release configuration in VS projects
9193 - review of compiler an linker options
9194 - VC .exe files are generated in bin_vc directory, not to interfere
9195 with binaries generated from other projects (cygwin, mingw, bcc ...)
9197 * sdcc/src/yacc.dsp: added
9199 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9200 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9201 and insert the version number definitions from .version
9203 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9205 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9206 added - genarate auto-host.h using auto-host_vc_in.h as template
9209 removed from CVS, generated automatically
9211 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9212 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9214 2002-08-11 Borut Razem <borut.razem AT siol.net>
9215 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9217 2002-08-10 Borut Razem <borut.razem AT siol.net>
9218 * src/SDCCmain.c (main):
9219 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9220 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9221 The consequence was that some temporary files were not removed.
9224 unification of code in functions tempfilename() and tempfile():
9225 function tempnam() is defined in Visual Studio 6.0 and .NET
9227 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9229 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9230 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9231 - removed compiler command line option /WX: Treats all warnings as errors
9232 - update a list of source files, included into the project
9234 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9235 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9236 changed project type to Generic Project so that can be correcly converted to VS.NET project
9238 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9240 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9242 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9244 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9245 added return 0 statements after assert() to make compiler happy
9247 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9248 added newline in the def file to keep MSC compiler satisfied
9250 * sdcc/src/z80/gen.c:
9251 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9252 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9253 - solved MSC error in function aopDump()
9255 * sdcc_vc.h: define PREFIX as "\\sdcc"
9257 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9258 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9297 2002-03-28 Johan Knol <johan AT balder>
9299 * src/SDCCval.c: fixed bug #532436
9301 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9303 Added "char *Processor" field to the port structure.
9306 Added -p option. Allows port dependent processor to be specified.
9309 Initialized the new field char *Processor field to NULL in all ports
9312 Compiler generated registers for interrupt context saving
9313 were not getting allocated.
9315 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9318 Fixed left shift. Will promote the left side of a left shift
9319 if a) left shifting more than size of operand or b) when assigned
9320 to something size > size of left side
9322 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9324 tons of changes. Register allocation has been
9325 rewritten. Added customization for the various PICs. Flow
9326 analysis is restructured. ...
9332 Added. device.c is a PIC port hack to accomodate variations
9335 2002-03-13 Michael Hope <michaelh AT vroom>
9337 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

9430 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9432 * sdcc/src/SDCCloop.c:
9433 Previous fix was not good. basic blocks that have "break" or "return" are
9434 not really partof a loop , but live ranges used in these blocks should
9435 be live thru the entire loop, so set partOfLoop but don't add them to
9438 2002-02-21 <johan AT FRIJA>
9440 * src/SDCCcse.c: fixed bug #514308
9442 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9445 Fixed BUG #519583. If a conditional block ended in a return/break
9446 statement inside a loop, it was not being considered part of the loop.
9448 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9450 2002-02-10 Karl Bongers <karl AT turbobit.com>
9453 Fixed up SDCDB debugger somewhat. Updated debugger/README
9454 with lots of comments and notes.
9456 * device/examples/test2.c:
9457 Fix bug, "red" variable not being initialized(compiler complained).
9459 * device/examples/Makefile, examples/test3.c:

9463 * sim/ucsim/cmd.src/cmdset.cc:
9464 Took out debug printfs in ucsim "next" command.
9467 Karl and Johan start ucsim XA support. Most dissassembly working,
9468 about 75% emulation done(plenty of work remaining).
9470 * sim/ucsim/z80.src:
9471 Add Z80 support to ucsim, add test-ucz80 regression test,
9472 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

9508 set preprocessor defines (depending on options)
9510 * src/SDCCicode.c, src/SDCCicode.h:
9511 changes made to handle multiple sends & receives
9514 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
