1964 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1965 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1966 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1967 always available in leading double underscore form. The C99 support is

2046 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2048 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2050 * device/lib/printf_large.c: removed inline assembly for portability and
2051 readability. Use printf_fast if speed or size are more important.
2052 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2053 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2055 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2057 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2058 prevent compiler warning
2060 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2062 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2063 moved to level 0 and declared as static. Also they are explicit
2064 placed in access bank. This was necessery because some times they
2065 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2066 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2067 optimizations. Currently only compare to unsigned char is implemented,
2068 * src/pic16/gen.c: added fReturnIdx array,
2069 * (struct resolvedIfx) is moved to gen.h and made public,
2070 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2071 * (aopForSym): added an optimization to directly store in stack of
2072 the operand of a SEND iCode,
2073 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2074 but as registers instead (AOP_REG) using the fReturnIdx array,
2075 * (pic16_freeAsmop): remove the freed register from the
2076 _G.sregsAlloc field,
2077 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2078 a compare of 'WREG',
2079 * (pic16_popGetTempRegCond): changed function prototype, now
2080 function takes also a bitVector argument v which holds the current
2081 set of registers that are allocated for stack access by aopForSym,
2082 registers allocated in aopForSym for accessing stack symbols are not
2083 any more part of the functions usedRegs field,
2084 * (genCall): some times aopOp is called for a stack variable to be
2085 send, aopForSym might perform the push, if this is true make sure
2086 that genCall doesn't push the variable twice by testing _G.resDirect,
2087 * (genFunction): changed testing for unspecified interrupt number
2088 from 256 to INTNO_UNSPEC,
2089 * modified selection scheme of frame pointer generation. Previously
2090 if function did use local registers a frame pointer was generated,
2091 now a frame pointer is generated only if function has arguments
2092 (that need PLUSW2 register access), or has stack arguments, or the
2093 compiler is not instructed to omit the frame pointer,
2094 * (genEndFunction): before restoring local registers that were saved
2095 in the function preamble, also restore the registers that *might*
2096 have been allocated for stack access,
2097 * (genRet): removed some old comments,
2098 * (genCmp, the active (RN's) version): added a call to the
2099 pic16_genCmp_special function to perform the compare with a more
2100 robust and optimized way,
2101 * (genInline): a feature has been added in inline code generation,
2102 which allows a wildcard variable substitution when writing inline
2103 assembly. Code is incomplete and experimental therefore undocumented,
2104 * (genCast): changed order of aopOp for result and right to allow
2105 aopForSym to directly load the result if possible,
2106 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2107 perform an optimized compare on some selected special occasions,
2108 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2109 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2110 generate an IVT any more,
2111 * src/pic16/main.c (pic16_optionsTable): added command line option
2113 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2114 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2116 * src/pic16/NOTES: Raphael Neider added in list of active developers
2117 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2118 jumptable_end to prevent bug #,
2119 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2120 inCond and outCond fields,
2121 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2122 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2123 turn off register spilling,
2124 * (packRegsForOneUse): synced with other ports' versions although it
2125 is not used currently,
2126 * (pic16_packRegisters): added an optimization while reading
2127 structure bitfields, some registers may be saved (malloc code is
2128 decreased by 80 bytes)
2130 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2132 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2133 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2134 this can be optimized more?
2136 2005-03-10 Raphael Neider <rneider AT web.de>
2138 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2139 genNearPointerGet): (hopefully) fixed access to bitfields via
2140 pointers (p->bitN = x; and x = p->bitN; failed)
2142 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
2144 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
2146 2005-03-09 Raphael Neider <rneider AT web.de>
2148 * src/SDCCopt.c (killDeadCode): fixed bug #1156016
2150 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
2152 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC
2153 * src/mcs51/ralloc.c (willCauseSpill): added check for REG_BIT type,

2774 Adding support for replacing ljmps with sjmps in jumptables
2775 generated for switch statements. For now you need to set the
2776 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2777 Now 4 algorithms for mcs51 jumptable generation are used:
2778 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2779 addresses loaded pc-relative for up to 112 cases and stack-pushing
2780 target addresses loaded with offset from dptr for up to 256 cases.

2810 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2812 * added libc directory. The current version of LibC contains string
2813 functions, ctype functions and macros and some functions of the
2814 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2815 be extensively tested in the future. Standard disclaimer here.
2816 Library is not automatically build yet. But one can build it by
2817 invoking 'make' inside the libc directory.

2828 * (pic16_storeForReturn): optimized return of 0,
2829 * (genCmp): experimental code for new genCmp which uses PIC18's
2830 special compare&skip instructions. Initial tests fail some times
2831 with variables grater than 1 byte in size, so new code is disabled,
2832 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2834 * (genCast): began a fix to optimize the casting of a bit to another
2835 bit, now assigning a bitfield to another bitfield will fail, sorry,

2844 and 1 for banking instruction,
2845 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2846 caused stop processing pCodes after a inline assembly block,
2847 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2848 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2849 registers when it shouldn't,
2850 * src/pic16/ralloc.c (allocReg): add preliminary support for
2851 supporting a limited set of temporary registers,
2853 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2855 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2856 genDataPointerSet): ensure assignments always copy in MSB to LSB
2858 (loadRegFromAop): recognize CLRH optimization,
2859 (genFunction): optimize RECEIVE iCodes in reentrant functions
2861 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2863 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5861 loaded with the linker search paths (-L arguments) and the libraries
5862 to be linked with the current source (-l arguments). Changes
5863 currently will affect only the pic16 port.
5864 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5865 include path the port specific paths and port specific libraries,
5866 * gplink command now contains the $3 argument,
5867 * src/pic16/device.h,

5884 Documenting changes from previous commits.
5885 * configure.in (version 1.56),
5886 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5887 when generating output files to configure the pic16 library,
5888 but now I've commented it out, since gputils aren't installed in the
5889 SF compile farm, so library won't compile
5891 * device/lib/Makefile.in (version 1.56): initially I've added in
5892 target 'all' the prerequestive 'model-pic16' so it compiled the
5893 pic16 library, but now I've commented it out for the same reasons
5895 * added targets 'model-pic16' and 'objects-pic16' to compile the
5897 * added target 'port-specific-objects-pic16' to handle the
5898 generated libraries and copy them into the build/ directory
5899 * added target 'clean-intermediate-pic16' to clean intermediate
5900 files into pic16 directory
5901 * in target 'installdirs' added line to create directory pic16 in

6166 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
6167 * src/SDCCsymt.c (newEnumType),
6169 * support/Util/SDCCerr.c,
6170 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
6172 * support/regression/tests/enum.c: added test for enum values that
6173 require at least 2 bytes of storage.
6175 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6177 * src/common.h: added ifndef/define/endif macros
6178 around the header file.
6179 Bug reported from Jesus Calvino-Fraga
6181 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6183 * sdcc.spec: updated
6184 * device/include/Makefile.in: don't install CVS directories
6185 * device/lib/Makefile.in: added removal of CVS directories after install
6186 * doc/Makefile: fixed install, added local_icons
6187 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6188 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6189 * src/ds390/gen.c (genRightShift): fixed bug #870788
6190 * src/SDCCast.c (decorateType): fixed bug #870781
6192 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6194 PIC16 port related changes:
6195 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6196 added variable stackPos,
6198 * gen.c: genCall, assignResultValue: added support for
6199 pushing/retrieving function parameters to/from stack,
6200 genFunction,genEndFunction: setup stack frame for the
6202 genAddrOf: will be changed according to bug 863624
6204 * added files genutils.c and genutils.h which contain gen*
6205 debugged and optimised functions extracted from gen.c
6207 * glue.c: added variable 'externs' which holds extern symbols,
6208 pic16emitRegularMap: is modified to properly handle relocatable
6209 symbols under the new scheme,
6210 pic16createInterruptVect: is modified
6211 pic16printPublics: is modified to emit 'global' assembler directives,
6212 added pic16_printExterns to print extern symbols,
6213 pic16glue: initializes stack/frame pointer in the beginning of
6214 the assembly output. Temporary hack, will be corrected later,
6215 because gplink yet does not support stack and SDCC does not
6216 yet support a type of crt0.o object to create the final binary.
6218 * Removed many lines that contain 8051 legacy code.
6219 * The code is finally placed under a 'code' directive.
6220 * Added port specific options.
6222 * _process_pragma: simplified since now we do not need *special*
6223 include file to define SFR registers. But a separate header
6224 will be needed. This will be developed later.
6225 * _pic16_parseOptions: added, parses port specific options:
6226 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6227 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6228 --preplace-udata-with=
6230 * _pic16_setDefaultOptions: modified to initialize section names,
6231 but hack is temporarly out of order since it needs improvement.
6232 * _pic16_genAssemblerPreamble: configuration words are emitted by
6233 their address instead of their name. This part is incomplete and
6234 supports only the 18Fxx2 devices. Other devices will emit an error
6235 during assembly since they do not contain the same set of config
6237 * _pic16_genIVT: is modified,
6239 * pcode.c: added definitions for some hardware registers that are needed
6241 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6242 All PCI entries are updated. Now LFSR is supported.
6243 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6244 * added pic16_newpCodeOpLit2 to support instructions with
6245 two literal arguments
6246 * pic16_pCode2str: corrected code that emits assembler instructions
6247 with two literal operands and those that have an access bit modifier
6248 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6249 this fixes a bug which caused some labels to be lost, when an
6250 assembler directive was added, i.e. banksel,
6251 * pic16_FixRegisterBanking: improved logic that causes the insertion
6253 * InlineFunction: functions that are called once, are not any more
6254 inlined. This can be a port option in the future,
6256 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6258 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6259 hold the corresponding uninitialized symbols,
6260 * pic16_allocProcessorRegister: registers have explicit marked the
6262 * pic16_allocInternalRegister: registers are explicit marked as
6264 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6265 processing list, so bit registers were lost,
6268 * ralloc.h: added field 'accessBank' and original symbol operand
6269 in register definition,
6270 * removed the field isMapped from register definition,
6272 ** Several functions have been removed from various sources:
6273 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6274 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6275 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6276 pic16_assignRelocatableRegisters
6278 ** others have been introduced:
6279 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6280 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6282 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6284 * support/scripts/inc2h.pl: changed definition of BIT_AT
6285 to emit 'sbit at' instead of 'bit at'. This was a request.
6287 PIC16 port related preliminary changes:
6288 * gen.c: prefixed function popRegFromString with
6289 pic16_ and all references to it corrected
6290 * pcode.c: all pic16_pc_* hardware registers prefixed
6291 with underscore (_),
6292 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6293 * ralloc.c: newReg(): when register is REG_SFR then
6294 set address to rIdx,
6295 pic16_allocProcessorRegister(): marks register wasUsed=0
6296 pic16_writeUsedRegs(): added a call to assign processor
6297 registers via pic16_assignFixedRegisters
6299 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6301 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6302 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6303 variables in unused register banks. Also the SSEG is placed
6304 wherever there is enough space for it, and IDATA can be anywhere
6305 in internal RAM. For now compile using -Wl-Y[stack_size].
6306 The mem file is different for this option as well, since it
6307 makes no sense of talking about DSEG lenght.
6309 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6311 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6312 in certain cases, e.g. when ROM assignment, patch provided
6313 from Albert den Haan.

6554 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6556 * src/SDCCast.c (decorateType): disabled a transformation I added in
6557 revision 1.188 (access to fields of a structure at an absolute address);
6558 it breaks with bitfields, extern declarations, and gcse analysis.
6559 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6560 could be assigned through a pointer, so don't complain.
6561 * src/SDCCast.c (astErrors),
6563 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7201 support for standard C idiom of memory mapped variables; for
7202 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7203 to xdata int at 0x1234 tempvar = 1.
7204 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7205 provided by Akiya ISHIDA

7221 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7223 Fixed bug #621531 (const & volatile confusion in the type chain).
7224 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

7316 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7317 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7318 fetching of the pointer
7319 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7320 copied from genNearPointerSet()
7321 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7322 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7336 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7338 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7339 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7340 type for bits was changed. It resulted in bit variables becoming
7341 global, which is not permitted in PIC 14 assembly output.
7343 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7345 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7358 A few small changes that speed up the peephole optimizer.
7362 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7364 Try to make the peephole optimizer smarter by maintaining
7365 an association between the assembly source code and the
7366 iCodes that originated them. Put this information to use
7367 with a new peephole rule condition "notVolatile" so that
7368 the rules can be aggressive yet still safe.
7373 * src/mcs51/peeph.def
7375 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7379 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7380 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7381 if the left or right operand symbols have the accuse flag set.
7383 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7385 Changed the type of the result of the ! (NOT) operator to char;
7386 previously it returned the same type as the source. This allows
7387 us to eliminate all the genFloatNot functions (all of its target
7388 implementations were very buggy) since !float can use the same
7391 * src/SDCCicode.c (ast2iCode): ! returns char

7400 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7401 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7402 during interrupts. Ensure WSAVE is located at a shared bank address.
7403 2. Fixed page selection in some places
7404 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7405 the registers name strings.
7406 4. Fixed "signed / unsigned compare" compiler warnings.
7407 5. The PIC port manages its own allocation of the general purpose
7408 registers, but makes no attempt to reuse them. As a result when
7409 compiling it soon runs out of general purpose registers. Some
7410 additional code was added to the files pcode.c and device.c to walk
7411 through the function call tree and rename the registers so that they
7421 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7422 genPlus() & genMinus() when the result is the same as left or right

7428 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7430 Made bitfield a distinct type from bit so that bitfields
7431 convert as per ANSI C and bits retain their traditional
7432 boolean style behaviour. Implemented bitfield support in
7440 * src/ds390/gen.c: bit v bitfield split
7441 * src/z80/gen.c: New support for bitfields
7442 * support/regression/tests/bitfields.c: reenabled z80,
7445 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7447 Rules 246.x, 247.x relate to bitfields, the others speed up
7448 access to xdata mapped I/O devices.
7450 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7452 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7454 Cleaned up genPackBits and genUnpackBits and added two helper
7455 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7456 for literal assignments in genPackBits (thanks to Frieder for
7462 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7464 Fixed bug #748310 (pointer to function type mishandled when the
7465 function name is omitted). Also fixed a SIGSEGV when a function
7466 attribute (reentrant, etc) is used on a non-function or on a
7467 function but misplaced before the parameter list.
7469 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7471 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7472 * support/Util/SDCCerr.h,
7473 * support/Util/SDCCerr.c: Added func attr misuse error msg

7494 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7496 Made the constant following the "interrupt" keyword optional. If
7497 omitted, the function will not automatically be given an entry
7498 in the interrupt vector table (similar to #pragma NOIV, but
7499 less syntacticly kludgy). The interrupt number is also now
7500 range checked. Also fixed a bug in the high order bit example

7514 * src/SDCCicode.c (operandOperation): rewritten some ops
7515 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7516 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7518 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7519 be re-activated by defining REDUCE_LITERALS)
7520 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7521 unsigned, but are signed by default
7522 * src/SDCCval.c (constVal): rearranged
7523 * src/SDCCval.c (valMod): preliminary fix
7524 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8030 added if/endif conditional macros to remove options help
8031 messages from optionsTable when a port is not configured, added
8032 support for the PIc16 port in the ports table, when executing
8033 the compiler with no port specified on command line, a default
8034 port is selected with the new macro DEFAULT_PORT which is
8035 defined in port.h, in setDefaultOptions() linkOptions is removed
8036 from initialization assignment, since now it is a set,
8037 parseCmdLine uses setParseWithComma for linkOptions, in
8038 linkEdit() linkOptions are accessed with new function indexSet()
8039 which returns the i'th item of a set variable. See SDCCset.c, in
8040 linkEdit() when calling buildCmdLine(), added linkOptions as
8041 last argument. Now users can pass arguments to gplink via the
8042 -Wl option, main() uses pic16glue() to glue up pic16 programs

8056 gpasm complaining and test the linkage with gplink, _linkCmd and
8057 _asmCmd changed to be more gplink and gpasm friendly
8058 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8059 produced an error when parsed, peep rule 12 is added to utilize
8060 movff, but it is commented out since the pCode does not support
8061 yet a command with 2 address arguments
8063 2003-05-18 <johan AT balder>
8065 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8092 2003-05-11 Borut Razem <borut.razem AT siol.net>
8094 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9094 2003-01-06 <karl AT turbobit.com>
9095 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
9098 2003-01-06 <johan AT balder>
9100 * src/SDCCicode.c: fixed array add
9102 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9103 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9104 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9106 2003-01-04 <johan AT balder>
9108 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9110 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9111 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9113 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9114 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9115 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9117 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9118 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9120 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9121 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9123 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9124 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9126 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9128 * in \sdcc\as\mcs51\ changed these files in order to create an
9129 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9130 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9131 following files to include the previous two files: aslink.dsp,
9132 Makefile.aslink, Makefile.bcc, and Makefile.in.
9134 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9135 .adb instead of .cdb
9137 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9139 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9140 value from option --iram-size.
9142 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9144 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9147 2002-09-18 <wiml AT hhhh.org>
9149 * SDCClrange.h: exposed setFromRange() and setToRange()
9150 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9151 packRegsForAccUse() (bug 542397)
9152 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9153 multiple times and emitting the fetch operations more than once
9154 added aopGetUsesAcc() function to allow binary operators to
9155 fetch their operands in the correct order; made genMinus() emit
9156 compact code for X = LITERAL - Y
9158 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9159 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9160 sprintf() in line 1267.
9162 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9163 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9166 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9167 Changes to aslink (All the changes are marked with 'JCF'):
9169 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9172 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9173 area BSEG. Also moves, if possible, the DATA area down into the internal
9174 ram so more space is available.
9176 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9179 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9180 not bytes. Function summary() which creates a memory usage summary
9181 file with extension .mem. Reports of overlaping stack and small stack
9182 size. If the space for the stack is less than 16 bytes aslink trows a
9185 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9186 the 8051. Option 'y' for memory summary output file.
9188 Changes to sdcc (All the changes are marked with 'JCF'):
9190 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9192 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9193 overlaying area for it (uses RegBankUsed[4]).
9195 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9196 bank zero as used by default. By default aslink locates the stack
9197 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9198 the creation of the .mem file. Delegates the allocation of data area
9199 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9200 the begining of the stack area to aslink.
9202 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9203 glue() in SDCCglue.c creates an area for it.
9205 2002-09-03 Borut Razem <borut.razem AT siol.net>
9206 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9207 sdcc/src/pic/glue.c:
9208 introduced atexit() handler for teporay files removal in case of
9209 errors, assertions, ...
9211 2002-08-29 Borut Razem <borut.razem AT siol.net>
9212 * sdcc/support/cpp2/auto-host_vc_in.h:
9213 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9214 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9215 Maybe there is a similar problem with BORLANDC? It should be checked!
9217 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9218 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9219 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9220 was not executed, and the compiler (cl) launched a warning:
9221 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9223 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9224 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9226 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9227 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
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 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9232 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9233 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9234 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9235 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9236 - added Release configuration in VS projects
9237 - review of compiler an linker options
9238 - VC .exe files are generated in bin_vc directory, not to interfere
9239 with binaries generated from other projects (cygwin, mingw, bcc ...)
9241 * sdcc/src/yacc.dsp: added
9243 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9244 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9245 and insert the version number definitions from .version
9247 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9249 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9250 added - genarate auto-host.h using auto-host_vc_in.h as template
9253 removed from CVS, generated automatically
9255 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9256 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9258 2002-08-11 Borut Razem <borut.razem AT siol.net>
9259 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9261 2002-08-10 Borut Razem <borut.razem AT siol.net>
9262 * src/SDCCmain.c (main):
9263 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9264 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9265 The consequence was that some temporary files were not removed.
9268 unification of code in functions tempfilename() and tempfile():
9269 function tempnam() is defined in Visual Studio 6.0 and .NET
9271 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9273 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9274 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9275 - removed compiler command line option /WX: Treats all warnings as errors
9276 - update a list of source files, included into the project
9278 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9279 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9280 changed project type to Generic Project so that can be correcly converted to VS.NET project
9282 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9284 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9286 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9288 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9289 added return 0 statements after assert() to make compiler happy
9291 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9292 added newline in the def file to keep MSC compiler satisfied
9294 * sdcc/src/z80/gen.c:
9295 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9296 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9297 - solved MSC error in function aopDump()
9299 * sdcc_vc.h: define PREFIX as "\\sdcc"
9301 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9302 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9341 2002-03-28 Johan Knol <johan AT balder>
9343 * src/SDCCval.c: fixed bug #532436
9345 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9347 Added "char *Processor" field to the port structure.
9350 Added -p option. Allows port dependent processor to be specified.
9353 Initialized the new field char *Processor field to NULL in all ports
9356 Compiler generated registers for interrupt context saving
9357 were not getting allocated.
9359 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9362 Fixed left shift. Will promote the left side of a left shift
9363 if a) left shifting more than size of operand or b) when assigned
9364 to something size > size of left side
9366 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9368 tons of changes. Register allocation has been
9369 rewritten. Added customization for the various PICs. Flow
9370 analysis is restructured. ...
9376 Added. device.c is a PIC port hack to accomodate variations
9379 2002-03-13 Michael Hope <michaelh AT vroom>
9381 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

9390 2002-03-04 bela <bela AT manik>
9392 * /device/include/mcs51reg.h:
9393 ds89c420 register definition update
9395 2002-03-03 <johan AT FRIJA>

9474 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9476 * sdcc/src/SDCCloop.c:
9477 Previous fix was not good. basic blocks that have "break" or "return" are
9478 not really partof a loop , but live ranges used in these blocks should
9479 be live thru the entire loop, so set partOfLoop but don't add them to
9482 2002-02-21 <johan AT FRIJA>
9484 * src/SDCCcse.c: fixed bug #514308
9486 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9489 Fixed BUG #519583. If a conditional block ended in a return/break
9490 statement inside a loop, it was not being considered part of the loop.
9492 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9494 2002-02-10 Karl Bongers <karl AT turbobit.com>
9497 Fixed up SDCDB debugger somewhat. Updated debugger/README
9498 with lots of comments and notes.
9500 * device/examples/test2.c:
9501 Fix bug, "red" variable not being initialized(compiler complained).
9503 * device/examples/Makefile, examples/test3.c:
9504 Add Makefile in device/examples folder, compiles test3.c
9505 for use as a multiple module SDCDB test case.
9507 * sim/ucsim/cmd.src/cmdset.cc:
9508 Took out debug printfs in ucsim "next" command.
9511 Karl and Johan start ucsim XA support. Most dissassembly working,
9512 about 75% emulation done(plenty of work remaining).
9514 * sim/ucsim/z80.src:
9515 Add Z80 support to ucsim, add test-ucz80 regression test,
9516 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
9517 Notice z80 compiler fails on examples/test3.c/crc code.

9535 2) ralloc can now allocate DPTR1 to some liveRanges
9537 * src/SDCCsymt.c, src/SDCCsymt.h:
9538 changes to handle multiple sends & receives
9541 added some pointer arithmetic optimization
9544 added some pointer arithmetic optimizations but not stable yet so not
9545 called from anywhere (will get this working shortly)
9547 * src/SDCCopt.c: fixed for multiple sends & receives
9550 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
9551 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
9552 set preprocessor defines (depending on options)
9554 * src/SDCCicode.c, src/SDCCicode.h:
9555 changes made to handle multiple sends & receives
9558 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
