1957 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1958 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1959 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1960 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1961 always available in leading double underscore form. The C99 support is

2040 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2042 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2044 * device/lib/printf_large.c: removed inline assembly for portability and
2045 readability. Use printf_fast if speed or size are more important.
2046 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2047 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2049 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2051 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2052 prevent compiler warning
2054 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2056 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2057 moved to level 0 and declared as static. Also they are explicit
2058 placed in access bank. This was necessery because some times they
2059 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2060 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2061 optimizations. Currently only compare to unsigned char is implemented,
2062 * src/pic16/gen.c: added fReturnIdx array,
2063 * (struct resolvedIfx) is moved to gen.h and made public,
2064 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2065 * (aopForSym): added an optimization to directly store in stack of
2066 the operand of a SEND iCode,
2067 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2068 but as registers instead (AOP_REG) using the fReturnIdx array,
2069 * (pic16_freeAsmop): remove the freed register from the
2070 _G.sregsAlloc field,
2071 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2072 a compare of 'WREG',
2073 * (pic16_popGetTempRegCond): changed function prototype, now
2074 function takes also a bitVector argument v which holds the current
2075 set of registers that are allocated for stack access by aopForSym,
2076 registers allocated in aopForSym for accessing stack symbols are not
2077 any more part of the functions usedRegs field,
2078 * (genCall): some times aopOp is called for a stack variable to be
2079 send, aopForSym might perform the push, if this is true make sure
2080 that genCall doesn't push the variable twice by testing _G.resDirect,
2081 * (genFunction): changed testing for unspecified interrupt number
2082 from 256 to INTNO_UNSPEC,
2083 * modified selection scheme of frame pointer generation. Previously
2084 if function did use local registers a frame pointer was generated,
2085 now a frame pointer is generated only if function has arguments
2086 (that need PLUSW2 register access), or has stack arguments, or the
2087 compiler is not instructed to omit the frame pointer,
2088 * (genEndFunction): before restoring local registers that were saved
2089 in the function preamble, also restore the registers that *might*
2090 have been allocated for stack access,
2091 * (genRet): removed some old comments,
2092 * (genCmp, the active (RN's) version): added a call to the
2093 pic16_genCmp_special function to perform the compare with a more
2094 robust and optimized way,
2095 * (genInline): a feature has been added in inline code generation,
2096 which allows a wildcard variable substitution when writing inline
2097 assembly. Code is incomplete and experimental therefore undocumented,
2098 * (genCast): changed order of aopOp for result and right to allow
2099 aopForSym to directly load the result if possible,
2100 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2101 perform an optimized compare on some selected special occasions,
2102 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2103 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2104 generate an IVT any more,
2105 * src/pic16/main.c (pic16_optionsTable): added command line option
2107 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2108 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2110 * src/pic16/NOTES: Raphael Neider added in list of active developers
2111 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2112 jumptable_end to prevent bug #,
2113 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2114 inCond and outCond fields,
2115 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2116 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2117 turn off register spilling,
2118 * (packRegsForOneUse): synced with other ports' versions although it
2119 is not used currently,
2120 * (pic16_packRegisters): added an optimization while reading
2121 structure bitfields, some registers may be saved (malloc code is
2122 decreased by 80 bytes)
2124 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2126 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2127 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2128 this can be optimized more?
2130 2005-03-10 Raphael Neider <rneider AT web.de>
2132 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2133 genNearPointerGet): (hopefully) fixed access to bitfields via
2134 pointers (p->bitN = x; and x = p->bitN; failed)
2136 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
2138 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

2768 Adding support for replacing ljmps with sjmps in jumptables
2769 generated for switch statements. For now you need to set the
2770 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2771 Now 4 algorithms for mcs51 jumptable generation are used:
2772 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2773 addresses loaded pc-relative for up to 112 cases and stack-pushing

2804 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2806 * added libc directory. The current version of LibC contains string
2807 functions, ctype functions and macros and some functions of the
2808 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2809 be extensively tested in the future. Standard disclaimer here.
2810 Library is not automatically build yet. But one can build it by
2811 invoking 'make' inside the libc directory.

2822 * (pic16_storeForReturn): optimized return of 0,
2823 * (genCmp): experimental code for new genCmp which uses PIC18's
2824 special compare&skip instructions. Initial tests fail some times
2825 with variables grater than 1 byte in size, so new code is disabled,
2826 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2828 * (genCast): began a fix to optimize the casting of a bit to another
2829 bit, now assigning a bitfield to another bitfield will fail, sorry,

2838 and 1 for banking instruction,
2839 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2840 caused stop processing pCodes after a inline assembly block,
2841 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2843 registers when it shouldn't,
2844 * src/pic16/ralloc.c (allocReg): add preliminary support for
2845 supporting a limited set of temporary registers,
2847 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2849 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2850 genDataPointerSet): ensure assignments always copy in MSB to LSB
2852 (loadRegFromAop): recognize CLRH optimization,
2853 (genFunction): optimize RECEIVE iCodes in reentrant functions
2855 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2857 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5855 loaded with the linker search paths (-L arguments) and the libraries
5856 to be linked with the current source (-l arguments). Changes
5857 currently will affect only the pic16 port.
5858 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5859 include path the port specific paths and port specific libraries,
5860 * gplink command now contains the $3 argument,
5861 * src/pic16/device.h,

5878 Documenting changes from previous commits.
5879 * configure.in (version 1.56),
5880 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5881 when generating output files to configure the pic16 library,
5882 but now I've commented it out, since gputils aren't installed in the
5883 SF compile farm, so library won't compile
5885 * device/lib/Makefile.in (version 1.56): initially I've added in
5886 target 'all' the prerequestive 'model-pic16' so it compiled the
5887 pic16 library, but now I've commented it out for the same reasons
5889 * added targets 'model-pic16' and 'objects-pic16' to compile the
5891 * added target 'port-specific-objects-pic16' to handle the
5892 generated libraries and copy them into the build/ directory
5893 * added target 'clean-intermediate-pic16' to clean intermediate
5894 files into pic16 directory
5895 * in target 'installdirs' added line to create directory pic16 in

6164 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
6166 * support/regression/tests/enum.c: added test for enum values that
6167 require at least 2 bytes of storage.
6169 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6171 * src/common.h: added ifndef/define/endif macros
6172 around the header file.
6173 Bug reported from Jesus Calvino-Fraga
6175 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6177 * sdcc.spec: updated
6178 * device/include/Makefile.in: don't install CVS directories
6179 * device/lib/Makefile.in: added removal of CVS directories after install
6180 * doc/Makefile: fixed install, added local_icons
6181 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6182 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6183 * src/ds390/gen.c (genRightShift): fixed bug #870788
6184 * src/SDCCast.c (decorateType): fixed bug #870781
6186 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6188 PIC16 port related changes:
6189 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6190 added variable stackPos,
6192 * gen.c: genCall, assignResultValue: added support for
6193 pushing/retrieving function parameters to/from stack,
6194 genFunction,genEndFunction: setup stack frame for the
6196 genAddrOf: will be changed according to bug 863624
6198 * added files genutils.c and genutils.h which contain gen*
6199 debugged and optimised functions extracted from gen.c
6201 * glue.c: added variable 'externs' which holds extern symbols,
6202 pic16emitRegularMap: is modified to properly handle relocatable
6203 symbols under the new scheme,
6204 pic16createInterruptVect: is modified
6205 pic16printPublics: is modified to emit 'global' assembler directives,
6206 added pic16_printExterns to print extern symbols,
6207 pic16glue: initializes stack/frame pointer in the beginning of
6208 the assembly output. Temporary hack, will be corrected later,
6209 because gplink yet does not support stack and SDCC does not
6210 yet support a type of crt0.o object to create the final binary.
6212 * Removed many lines that contain 8051 legacy code.
6213 * The code is finally placed under a 'code' directive.
6214 * Added port specific options.
6216 * _process_pragma: simplified since now we do not need *special*
6217 include file to define SFR registers. But a separate header
6218 will be needed. This will be developed later.
6219 * _pic16_parseOptions: added, parses port specific options:
6220 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6221 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6222 --preplace-udata-with=
6224 * _pic16_setDefaultOptions: modified to initialize section names,
6225 but hack is temporarly out of order since it needs improvement.
6226 * _pic16_genAssemblerPreamble: configuration words are emitted by
6227 their address instead of their name. This part is incomplete and
6228 supports only the 18Fxx2 devices. Other devices will emit an error
6229 during assembly since they do not contain the same set of config
6231 * _pic16_genIVT: is modified,
6233 * pcode.c: added definitions for some hardware registers that are needed
6235 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6236 All PCI entries are updated. Now LFSR is supported.
6237 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6238 * added pic16_newpCodeOpLit2 to support instructions with
6239 two literal arguments
6240 * pic16_pCode2str: corrected code that emits assembler instructions
6241 with two literal operands and those that have an access bit modifier
6242 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6243 this fixes a bug which caused some labels to be lost, when an
6244 assembler directive was added, i.e. banksel,
6245 * pic16_FixRegisterBanking: improved logic that causes the insertion
6247 * InlineFunction: functions that are called once, are not any more
6248 inlined. This can be a port option in the future,
6250 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6252 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6253 hold the corresponding uninitialized symbols,
6254 * pic16_allocProcessorRegister: registers have explicit marked the
6256 * pic16_allocInternalRegister: registers are explicit marked as
6258 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6259 processing list, so bit registers were lost,
6262 * ralloc.h: added field 'accessBank' and original symbol operand
6263 in register definition,
6264 * removed the field isMapped from register definition,
6266 ** Several functions have been removed from various sources:
6267 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6268 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6269 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6270 pic16_assignRelocatableRegisters
6272 ** others have been introduced:
6273 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6274 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6276 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6278 * support/scripts/inc2h.pl: changed definition of BIT_AT
6279 to emit 'sbit at' instead of 'bit at'. This was a request.
6281 PIC16 port related preliminary changes:
6282 * gen.c: prefixed function popRegFromString with
6283 pic16_ and all references to it corrected
6284 * pcode.c: all pic16_pc_* hardware registers prefixed
6285 with underscore (_),
6286 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6287 * ralloc.c: newReg(): when register is REG_SFR then
6288 set address to rIdx,
6289 pic16_allocProcessorRegister(): marks register wasUsed=0
6290 pic16_writeUsedRegs(): added a call to assign processor
6291 registers via pic16_assignFixedRegisters
6293 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6295 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6296 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6297 variables in unused register banks. Also the SSEG is placed
6298 wherever there is enough space for it, and IDATA can be anywhere
6299 in internal RAM. For now compile using -Wl-Y[stack_size].
6300 The mem file is different for this option as well, since it
6301 makes no sense of talking about DSEG lenght.
6303 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6305 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6306 in certain cases, e.g. when ROM assignment, patch provided
6307 from Albert den Haan.
6309 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6452 * src/mcs51/peephole.def,
6453 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

6465 multiply defined with mismatching "at" address.
6467 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6469 * src/ds390/main.c (PORT tininative_port): fixed bug #858416
6470 * src/SDCCglue.c (printChar, printIvalChar, emitStaticSeg),

6548 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6550 * src/SDCCast.c (decorateType): disabled a transformation I added in
6551 revision 1.188 (access to fields of a structure at an absolute address);
6552 it breaks with bitfields, extern declarations, and gcse analysis.
6553 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6554 could be assigned through a pointer, so don't complain.
6555 * src/SDCCast.c (astErrors),
6557 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7195 support for standard C idiom of memory mapped variables; for
7196 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7197 to xdata int at 0x1234 tempvar = 1.
7198 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7199 provided by Akiya ISHIDA

7215 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7217 Fixed bug #621531 (const & volatile confusion in the type chain).
7218 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
7219 refer to the const or volatile state of the pointer itself.

7284 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
7285 pcoderegs.h, ralloc.c, ralloc.h
7286 * main.c: added top header and GPL license notice

7310 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7311 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7312 fetching of the pointer
7313 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7314 copied from genNearPointerSet()
7315 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7316 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7317 If they pop r0/r1 they must be called in the opposite order than aopOp().
7318 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7319 (resp. --stack-auto), prepared for --xstack

7330 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7332 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7333 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7334 type for bits was changed. It resulted in bit variables becoming
7335 global, which is not permitted in PIC 14 assembly output.
7337 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7339 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7352 A few small changes that speed up the peephole optimizer.
7356 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7358 Try to make the peephole optimizer smarter by maintaining
7359 an association between the assembly source code and the
7360 iCodes that originated them. Put this information to use
7361 with a new peephole rule condition "notVolatile" so that
7362 the rules can be aggressive yet still safe.
7367 * src/mcs51/peeph.def
7369 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7373 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7374 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7375 if the left or right operand symbols have the accuse flag set.
7377 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7379 Changed the type of the result of the ! (NOT) operator to char;
7380 previously it returned the same type as the source. This allows
7381 us to eliminate all the genFloatNot functions (all of its target
7382 implementations were very buggy) since !float can use the same
7385 * src/SDCCicode.c (ast2iCode): ! returns char

7394 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7395 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7396 during interrupts. Ensure WSAVE is located at a shared bank address.
7397 2. Fixed page selection in some places
7398 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7399 the registers name strings.
7400 4. Fixed "signed / unsigned compare" compiler warnings.
7401 5. The PIC port manages its own allocation of the general purpose
7402 registers, but makes no attempt to reuse them. As a result when
7403 compiling it soon runs out of general purpose registers. Some
7404 additional code was added to the files pcode.c and device.c to walk
7405 through the function call tree and rename the registers so that they
7415 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7416 genPlus() & genMinus() when the result is the same as left or right
7418 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7422 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7424 Made bitfield a distinct type from bit so that bitfields
7425 convert as per ANSI C and bits retain their traditional
7426 boolean style behaviour. Implemented bitfield support in
7434 * src/ds390/gen.c: bit v bitfield split
7435 * src/z80/gen.c: New support for bitfields
7436 * support/regression/tests/bitfields.c: reenabled z80,
7439 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7441 Rules 246.x, 247.x relate to bitfields, the others speed up
7442 access to xdata mapped I/O devices.
7444 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7446 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7448 Cleaned up genPackBits and genUnpackBits and added two helper
7449 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7450 for literal assignments in genPackBits (thanks to Frieder for
7456 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7458 Fixed bug #748310 (pointer to function type mishandled when the
7459 function name is omitted). Also fixed a SIGSEGV when a function
7460 attribute (reentrant, etc) is used on a non-function or on a
7461 function but misplaced before the parameter list.
7463 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7465 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7466 * support/Util/SDCCerr.h,
7467 * support/Util/SDCCerr.c: Added func attr misuse error msg

7488 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7490 Made the constant following the "interrupt" keyword optional. If
7491 omitted, the function will not automatically be given an entry
7492 in the interrupt vector table (similar to #pragma NOIV, but
7493 less syntacticly kludgy). The interrupt number is also now
7494 range checked. Also fixed a bug in the high order bit example

7508 * src/SDCCicode.c (operandOperation): rewritten some ops
7509 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7510 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7512 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7513 be re-activated by defining REDUCE_LITERALS)
7514 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7515 unsigned, but are signed by default
7516 * src/SDCCval.c (constVal): rearranged
7517 * src/SDCCval.c (valMod): preliminary fix
7518 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8024 added if/endif conditional macros to remove options help
8025 messages from optionsTable when a port is not configured, added
8026 support for the PIc16 port in the ports table, when executing
8027 the compiler with no port specified on command line, a default
8028 port is selected with the new macro DEFAULT_PORT which is
8029 defined in port.h, in setDefaultOptions() linkOptions is removed
8030 from initialization assignment, since now it is a set,
8031 parseCmdLine uses setParseWithComma for linkOptions, in
8032 linkEdit() linkOptions are accessed with new function indexSet()
8033 which returns the i'th item of a set variable. See SDCCset.c, in
8034 linkEdit() when calling buildCmdLine(), added linkOptions as
8035 last argument. Now users can pass arguments to gplink via the
8036 -Wl option, main() uses pic16glue() to glue up pic16 programs

8050 gpasm complaining and test the linkage with gplink, _linkCmd and
8051 _asmCmd changed to be more gplink and gpasm friendly
8052 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8053 produced an error when parsed, peep rule 12 is added to utilize
8054 movff, but it is commented out since the pCode does not support
8055 yet a command with 2 address arguments
8057 2003-05-18 <johan AT balder>
8059 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8086 2003-05-11 Borut Razem <borut.razem AT siol.net>
8088 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9096 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9097 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9098 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9100 2003-01-04 <johan AT balder>
9102 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9104 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9105 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9107 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9108 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9109 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9111 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9112 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9114 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9115 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9117 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9118 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9120 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9122 * in \sdcc\as\mcs51\ changed these files in order to create an
9123 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9124 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9125 following files to include the previous two files: aslink.dsp,
9126 Makefile.aslink, Makefile.bcc, and Makefile.in.
9128 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9129 .adb instead of .cdb
9131 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9133 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9134 value from option --iram-size.
9136 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9138 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9141 2002-09-18 <wiml AT hhhh.org>
9143 * SDCClrange.h: exposed setFromRange() and setToRange()
9144 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9145 packRegsForAccUse() (bug 542397)
9146 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9147 multiple times and emitting the fetch operations more than once
9148 added aopGetUsesAcc() function to allow binary operators to
9149 fetch their operands in the correct order; made genMinus() emit
9150 compact code for X = LITERAL - Y
9152 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9153 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9154 sprintf() in line 1267.
9156 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9157 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9160 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9161 Changes to aslink (All the changes are marked with 'JCF'):
9163 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9166 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9167 area BSEG. Also moves, if possible, the DATA area down into the internal
9168 ram so more space is available.
9170 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9173 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9174 not bytes. Function summary() which creates a memory usage summary
9175 file with extension .mem. Reports of overlaping stack and small stack
9176 size. If the space for the stack is less than 16 bytes aslink trows a
9179 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9180 the 8051. Option 'y' for memory summary output file.
9182 Changes to sdcc (All the changes are marked with 'JCF'):
9184 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9186 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9187 overlaying area for it (uses RegBankUsed[4]).
9189 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9190 bank zero as used by default. By default aslink locates the stack
9191 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9192 the creation of the .mem file. Delegates the allocation of data area
9193 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9194 the begining of the stack area to aslink.
9196 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9197 glue() in SDCCglue.c creates an area for it.
9199 2002-09-03 Borut Razem <borut.razem AT siol.net>
9200 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9201 sdcc/src/pic/glue.c:
9202 introduced atexit() handler for teporay files removal in case of
9203 errors, assertions, ...
9205 2002-08-29 Borut Razem <borut.razem AT siol.net>
9206 * sdcc/support/cpp2/auto-host_vc_in.h:
9207 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9208 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9209 Maybe there is a similar problem with BORLANDC? It should be checked!
9211 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9212 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9213 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9214 was not executed, and the compiler (cl) launched a warning:
9215 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9217 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9218 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9220 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9221 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9223 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9224 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9225 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9226 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9227 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9228 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9229 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9230 - added Release configuration in VS projects
9231 - review of compiler an linker options
9232 - VC .exe files are generated in bin_vc directory, not to interfere
9233 with binaries generated from other projects (cygwin, mingw, bcc ...)
9235 * sdcc/src/yacc.dsp: added
9237 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9238 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9239 and insert the version number definitions from .version
9241 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9243 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9244 added - genarate auto-host.h using auto-host_vc_in.h as template
9247 removed from CVS, generated automatically
9249 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9250 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9252 2002-08-11 Borut Razem <borut.razem AT siol.net>
9253 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9255 2002-08-10 Borut Razem <borut.razem AT siol.net>
9256 * src/SDCCmain.c (main):
9257 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9258 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9259 The consequence was that some temporary files were not removed.
9262 unification of code in functions tempfilename() and tempfile():
9263 function tempnam() is defined in Visual Studio 6.0 and .NET
9265 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9267 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9268 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9269 - removed compiler command line option /WX: Treats all warnings as errors
9270 - update a list of source files, included into the project
9272 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9273 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9274 changed project type to Generic Project so that can be correcly converted to VS.NET project
9276 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9278 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9280 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9282 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9283 added return 0 statements after assert() to make compiler happy
9285 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9286 added newline in the def file to keep MSC compiler satisfied
9288 * sdcc/src/z80/gen.c:
9289 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9290 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9291 - solved MSC error in function aopDump()
9293 * sdcc_vc.h: define PREFIX as "\\sdcc"
9295 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9296 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9299 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9300 - Rewrote the register banking algorithm.
9301 - Added pCode live-range analysis to registers (for now, only non-used and
9302 singly-used registers optimized away)
9304 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9306 * 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.

9335 2002-03-28 Johan Knol <johan AT balder>
9337 * src/SDCCval.c: fixed bug #532436
9339 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9341 Added "char *Processor" field to the port structure.
9344 Added -p option. Allows port dependent processor to be specified.
9347 Initialized the new field char *Processor field to NULL in all ports
9350 Compiler generated registers for interrupt context saving
9351 were not getting allocated.
9353 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9356 Fixed left shift. Will promote the left side of a left shift
9357 if a) left shifting more than size of operand or b) when assigned
9358 to something size > size of left side
9360 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9362 tons of changes. Register allocation has been
9363 rewritten. Added customization for the various PICs. Flow
9364 analysis is restructured. ...
9370 Added. device.c is a PIC port hack to accomodate variations
9373 2002-03-13 Michael Hope <michaelh AT vroom>
9375 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

9384 2002-03-04 bela <bela AT manik>
9386 * /device/include/mcs51reg.h:
9387 ds89c420 register definition update

9468 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9470 * sdcc/src/SDCCloop.c:
9471 Previous fix was not good. basic blocks that have "break" or "return" are
9472 not really partof a loop , but live ranges used in these blocks should
9473 be live thru the entire loop, so set partOfLoop but don't add them to
9476 2002-02-21 <johan AT FRIJA>
9478 * src/SDCCcse.c: fixed bug #514308
9480 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9483 Fixed BUG #519583. If a conditional block ended in a return/break
9484 statement inside a loop, it was not being considered part of the loop.
9486 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9488 2002-02-10 Karl Bongers <karl AT turbobit.com>
9491 Fixed up SDCDB debugger somewhat. Updated debugger/README
9492 with lots of comments and notes.
9494 * device/examples/test2.c:
9495 Fix bug, "red" variable not being initialized(compiler complained).
9497 * device/examples/Makefile, examples/test3.c:
9498 Add Makefile in device/examples folder, compiles test3.c
9499 for use as a multiple module SDCDB test case.
9501 * sim/ucsim/cmd.src/cmdset.cc:
9502 Took out debug printfs in ucsim "next" command.
9505 Karl and Johan start ucsim XA support. Most dissassembly working,
9506 about 75% emulation done(plenty of work remaining).
9508 * sim/ucsim/z80.src:
9509 Add Z80 support to ucsim, add test-ucz80 regression test,
9510 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

9544 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
9545 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
9546 set preprocessor defines (depending on options)
9548 * src/SDCCicode.c, src/SDCCicode.h:
9549 changes made to handle multiple sends & receives
9552 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
