2045 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2047 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2049 * device/lib/printf_large.c: removed inline assembly for portability and
2050 readability. Use printf_fast if speed or size are more important.
2051 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2052 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2054 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2056 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2057 prevent compiler warning
2059 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2061 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2062 moved to level 0 and declared as static. Also they are explicit
2063 placed in access bank. This was necessery because some times they
2064 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2065 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2066 optimizations. Currently only compare to unsigned char is implemented,
2067 * src/pic16/gen.c: added fReturnIdx array,
2068 * (struct resolvedIfx) is moved to gen.h and made public,
2069 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2070 * (aopForSym): added an optimization to directly store in stack of
2071 the operand of a SEND iCode,
2072 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2073 but as registers instead (AOP_REG) using the fReturnIdx array,
2074 * (pic16_freeAsmop): remove the freed register from the
2075 _G.sregsAlloc field,
2076 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2077 a compare of 'WREG',
2078 * (pic16_popGetTempRegCond): changed function prototype, now
2079 function takes also a bitVector argument v which holds the current
2080 set of registers that are allocated for stack access by aopForSym,
2081 registers allocated in aopForSym for accessing stack symbols are not
2082 any more part of the functions usedRegs field,
2083 * (genCall): some times aopOp is called for a stack variable to be
2084 send, aopForSym might perform the push, if this is true make sure
2085 that genCall doesn't push the variable twice by testing _G.resDirect,
2086 * (genFunction): changed testing for unspecified interrupt number
2087 from 256 to INTNO_UNSPEC,
2088 * modified selection scheme of frame pointer generation. Previously
2089 if function did use local registers a frame pointer was generated,
2090 now a frame pointer is generated only if function has arguments
2091 (that need PLUSW2 register access), or has stack arguments, or the
2092 compiler is not instructed to omit the frame pointer,
2093 * (genEndFunction): before restoring local registers that were saved
2094 in the function preamble, also restore the registers that *might*
2095 have been allocated for stack access,
2096 * (genRet): removed some old comments,
2097 * (genCmp, the active (RN's) version): added a call to the
2098 pic16_genCmp_special function to perform the compare with a more
2099 robust and optimized way,
2100 * (genInline): a feature has been added in inline code generation,
2101 which allows a wildcard variable substitution when writing inline
2102 assembly. Code is incomplete and experimental therefore undocumented,
2103 * (genCast): changed order of aopOp for result and right to allow
2104 aopForSym to directly load the result if possible,
2105 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2106 perform an optimized compare on some selected special occasions,
2107 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2108 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2109 generate an IVT any more,
2110 * src/pic16/main.c (pic16_optionsTable): added command line option
2112 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2113 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2115 * src/pic16/NOTES: Raphael Neider added in list of active developers
2116 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2117 jumptable_end to prevent bug #,
2118 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2119 inCond and outCond fields,
2120 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2121 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2122 turn off register spilling,
2123 * (packRegsForOneUse): synced with other ports' versions although it
2124 is not used currently,
2125 * (pic16_packRegisters): added an optimization while reading
2126 structure bitfields, some registers may be saved (malloc code is
2127 decreased by 80 bytes)
2129 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2131 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2132 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2133 this can be optimized more?
2135 2005-03-10 Raphael Neider <rneider AT web.de>
2137 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2138 genNearPointerGet): (hopefully) fixed access to bitfields via
2139 pointers (p->bitN = x; and x = p->bitN; failed)
2141 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
2143 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
2145 2005-03-09 Raphael Neider <rneider AT web.de>

2149 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
2151 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC
2152 * src/mcs51/ralloc.c (willCauseSpill): added check for REG_BIT type,

2773 Adding support for replacing ljmps with sjmps in jumptables
2774 generated for switch statements. For now you need to set the
2775 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2776 Now 4 algorithms for mcs51 jumptable generation are used:
2777 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2778 addresses loaded pc-relative for up to 112 cases and stack-pushing
2779 target addresses loaded with offset from dptr for up to 256 cases.

2809 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2811 * added libc directory. The current version of LibC contains string
2812 functions, ctype functions and macros and some functions of the
2813 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2814 be extensively tested in the future. Standard disclaimer here.
2815 Library is not automatically build yet. But one can build it by
2816 invoking 'make' inside the libc directory.

2827 * (pic16_storeForReturn): optimized return of 0,
2828 * (genCmp): experimental code for new genCmp which uses PIC18's
2829 special compare&skip instructions. Initial tests fail some times
2830 with variables grater than 1 byte in size, so new code is disabled,
2831 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2833 * (genCast): began a fix to optimize the casting of a bit to another
2834 bit, now assigning a bitfield to another bitfield will fail, sorry,

2843 and 1 for banking instruction,
2844 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2845 caused stop processing pCodes after a inline assembly block,
2846 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2847 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2848 registers when it shouldn't,
2849 * src/pic16/ralloc.c (allocReg): add preliminary support for
2850 supporting a limited set of temporary registers,
2852 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2854 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2855 genDataPointerSet): ensure assignments always copy in MSB to LSB
2857 (loadRegFromAop): recognize CLRH optimization,
2858 (genFunction): optimize RECEIVE iCodes in reentrant functions
2860 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2862 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5860 loaded with the linker search paths (-L arguments) and the libraries
5861 to be linked with the current source (-l arguments). Changes
5862 currently will affect only the pic16 port.
5863 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5864 include path the port specific paths and port specific libraries,
5865 * gplink command now contains the $3 argument,
5866 * src/pic16/device.h,

5883 Documenting changes from previous commits.
5884 * configure.in (version 1.56),
5885 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5886 when generating output files to configure the pic16 library,
5887 but now I've commented it out, since gputils aren't installed in the
5888 SF compile farm, so library won't compile
5890 * device/lib/Makefile.in (version 1.56): initially I've added in
5891 target 'all' the prerequestive 'model-pic16' so it compiled the
5892 pic16 library, but now I've commented it out for the same reasons
5894 * added targets 'model-pic16' and 'objects-pic16' to compile the
5896 * added target 'port-specific-objects-pic16' to handle the
5897 generated libraries and copy them into the build/ directory
5898 * added target 'clean-intermediate-pic16' to clean intermediate
5899 files into pic16 directory
5900 * in target 'installdirs' added line to create directory pic16 in

6165 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
6166 * src/SDCCsymt.c (newEnumType),
6168 * support/Util/SDCCerr.c,
6169 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
6171 * support/regression/tests/enum.c: added test for enum values that
6172 require at least 2 bytes of storage.
6174 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6176 * src/common.h: added ifndef/define/endif macros
6177 around the header file.
6178 Bug reported from Jesus Calvino-Fraga
6180 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6182 * sdcc.spec: updated
6183 * device/include/Makefile.in: don't install CVS directories
6184 * device/lib/Makefile.in: added removal of CVS directories after install
6185 * doc/Makefile: fixed install, added local_icons
6186 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6187 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6188 * src/ds390/gen.c (genRightShift): fixed bug #870788
6189 * src/SDCCast.c (decorateType): fixed bug #870781
6191 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6193 PIC16 port related changes:
6194 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6195 added variable stackPos,
6197 * gen.c: genCall, assignResultValue: added support for
6198 pushing/retrieving function parameters to/from stack,
6199 genFunction,genEndFunction: setup stack frame for the
6201 genAddrOf: will be changed according to bug 863624
6203 * added files genutils.c and genutils.h which contain gen*
6204 debugged and optimised functions extracted from gen.c
6206 * glue.c: added variable 'externs' which holds extern symbols,
6207 pic16emitRegularMap: is modified to properly handle relocatable
6208 symbols under the new scheme,
6209 pic16createInterruptVect: is modified
6210 pic16printPublics: is modified to emit 'global' assembler directives,
6211 added pic16_printExterns to print extern symbols,
6212 pic16glue: initializes stack/frame pointer in the beginning of
6213 the assembly output. Temporary hack, will be corrected later,
6214 because gplink yet does not support stack and SDCC does not
6215 yet support a type of crt0.o object to create the final binary.
6217 * Removed many lines that contain 8051 legacy code.
6218 * The code is finally placed under a 'code' directive.
6219 * Added port specific options.
6221 * _process_pragma: simplified since now we do not need *special*
6222 include file to define SFR registers. But a separate header
6223 will be needed. This will be developed later.
6224 * _pic16_parseOptions: added, parses port specific options:
6225 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6226 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6227 --preplace-udata-with=
6229 * _pic16_setDefaultOptions: modified to initialize section names,
6230 but hack is temporarly out of order since it needs improvement.
6231 * _pic16_genAssemblerPreamble: configuration words are emitted by
6232 their address instead of their name. This part is incomplete and
6233 supports only the 18Fxx2 devices. Other devices will emit an error
6234 during assembly since they do not contain the same set of config
6236 * _pic16_genIVT: is modified,
6238 * pcode.c: added definitions for some hardware registers that are needed
6240 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6241 All PCI entries are updated. Now LFSR is supported.
6242 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6243 * added pic16_newpCodeOpLit2 to support instructions with
6244 two literal arguments
6245 * pic16_pCode2str: corrected code that emits assembler instructions
6246 with two literal operands and those that have an access bit modifier
6247 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6248 this fixes a bug which caused some labels to be lost, when an
6249 assembler directive was added, i.e. banksel,
6250 * pic16_FixRegisterBanking: improved logic that causes the insertion
6252 * InlineFunction: functions that are called once, are not any more
6253 inlined. This can be a port option in the future,
6255 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6257 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6258 hold the corresponding uninitialized symbols,
6259 * pic16_allocProcessorRegister: registers have explicit marked the
6261 * pic16_allocInternalRegister: registers are explicit marked as
6263 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6264 processing list, so bit registers were lost,
6267 * ralloc.h: added field 'accessBank' and original symbol operand
6268 in register definition,
6269 * removed the field isMapped from register definition,
6271 ** Several functions have been removed from various sources:
6272 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6273 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6274 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6275 pic16_assignRelocatableRegisters
6277 ** others have been introduced:
6278 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6279 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6281 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6283 * support/scripts/inc2h.pl: changed definition of BIT_AT
6284 to emit 'sbit at' instead of 'bit at'. This was a request.
6286 PIC16 port related preliminary changes:
6287 * gen.c: prefixed function popRegFromString with
6288 pic16_ and all references to it corrected
6289 * pcode.c: all pic16_pc_* hardware registers prefixed
6290 with underscore (_),
6291 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6292 * ralloc.c: newReg(): when register is REG_SFR then
6293 set address to rIdx,
6294 pic16_allocProcessorRegister(): marks register wasUsed=0
6295 pic16_writeUsedRegs(): added a call to assign processor
6296 registers via pic16_assignFixedRegisters
6298 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6300 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6301 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6302 variables in unused register banks. Also the SSEG is placed
6303 wherever there is enough space for it, and IDATA can be anywhere
6304 in internal RAM. For now compile using -Wl-Y[stack_size].
6305 The mem file is different for this option as well, since it
6306 makes no sense of talking about DSEG lenght.
6308 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6310 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6311 in certain cases, e.g. when ROM assignment, patch provided
6312 from Albert den Haan.

6553 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6555 * src/SDCCast.c (decorateType): disabled a transformation I added in
6556 revision 1.188 (access to fields of a structure at an absolute address);
6557 it breaks with bitfields, extern declarations, and gcse analysis.
6558 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6559 could be assigned through a pointer, so don't complain.
6560 * src/SDCCast.c (astErrors),
6562 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7200 support for standard C idiom of memory mapped variables; for
7201 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7202 to xdata int at 0x1234 tempvar = 1.
7203 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7204 provided by Akiya ISHIDA

7220 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7222 Fixed bug #621531 (const & volatile confusion in the type chain).
7223 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

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

7335 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7337 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7338 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7339 type for bits was changed. It resulted in bit variables becoming
7340 global, which is not permitted in PIC 14 assembly output.
7342 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7344 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7357 A few small changes that speed up the peephole optimizer.
7361 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7363 Try to make the peephole optimizer smarter by maintaining
7364 an association between the assembly source code and the
7365 iCodes that originated them. Put this information to use
7366 with a new peephole rule condition "notVolatile" so that
7367 the rules can be aggressive yet still safe.
7372 * src/mcs51/peeph.def
7374 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7378 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7379 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7380 if the left or right operand symbols have the accuse flag set.
7382 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7384 Changed the type of the result of the ! (NOT) operator to char;
7385 previously it returned the same type as the source. This allows
7386 us to eliminate all the genFloatNot functions (all of its target
7387 implementations were very buggy) since !float can use the same

7399 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7400 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7401 during interrupts. Ensure WSAVE is located at a shared bank address.
7402 2. Fixed page selection in some places
7403 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7404 the registers name strings.
7405 4. Fixed "signed / unsigned compare" compiler warnings.
7406 5. The PIC port manages its own allocation of the general purpose
7407 registers, but makes no attempt to reuse them. As a result when
7408 compiling it soon runs out of general purpose registers. Some
7409 additional code was added to the files pcode.c and device.c to walk
7410 through the function call tree and rename the registers so that they
7420 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7421 genPlus() & genMinus() when the result is the same as left or right

7427 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7429 Made bitfield a distinct type from bit so that bitfields
7430 convert as per ANSI C and bits retain their traditional
7431 boolean style behaviour. Implemented bitfield support in
7439 * src/ds390/gen.c: bit v bitfield split
7440 * src/z80/gen.c: New support for bitfields
7441 * support/regression/tests/bitfields.c: reenabled z80,
7444 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7446 Rules 246.x, 247.x relate to bitfields, the others speed up
7447 access to xdata mapped I/O devices.
7449 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7451 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7453 Cleaned up genPackBits and genUnpackBits and added two helper
7454 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7455 for literal assignments in genPackBits (thanks to Frieder for
7461 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7463 Fixed bug #748310 (pointer to function type mishandled when the
7464 function name is omitted). Also fixed a SIGSEGV when a function
7465 attribute (reentrant, etc) is used on a non-function or on a
7466 function but misplaced before the parameter list.
7468 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7470 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7471 * support/Util/SDCCerr.h,

7493 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7495 Made the constant following the "interrupt" keyword optional. If
7496 omitted, the function will not automatically be given an entry
7497 in the interrupt vector table (similar to #pragma NOIV, but
7498 less syntacticly kludgy). The interrupt number is also now
7499 range checked. Also fixed a bug in the high order bit example

7513 * src/SDCCicode.c (operandOperation): rewritten some ops
7514 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7515 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7517 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7518 be re-activated by defining REDUCE_LITERALS)
7519 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7520 unsigned, but are signed by default
7521 * src/SDCCval.c (constVal): rearranged
7522 * src/SDCCval.c (valMod): preliminary fix
7523 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8029 added if/endif conditional macros to remove options help
8030 messages from optionsTable when a port is not configured, added
8031 support for the PIc16 port in the ports table, when executing
8032 the compiler with no port specified on command line, a default
8033 port is selected with the new macro DEFAULT_PORT which is
8034 defined in port.h, in setDefaultOptions() linkOptions is removed
8035 from initialization assignment, since now it is a set,
8036 parseCmdLine uses setParseWithComma for linkOptions, in
8037 linkEdit() linkOptions are accessed with new function indexSet()
8038 which returns the i'th item of a set variable. See SDCCset.c, in
8039 linkEdit() when calling buildCmdLine(), added linkOptions as
8040 last argument. Now users can pass arguments to gplink via the
8041 -Wl option, main() uses pic16glue() to glue up pic16 programs

8055 gpasm complaining and test the linkage with gplink, _linkCmd and
8056 _asmCmd changed to be more gplink and gpasm friendly
8057 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8058 produced an error when parsed, peep rule 12 is added to utilize
8059 movff, but it is commented out since the pCode does not support
8060 yet a command with 2 address arguments
8062 2003-05-18 <johan AT balder>
8064 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9093 2003-01-06 <karl AT turbobit.com>
9094 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
9097 2003-01-06 <johan AT balder>
9099 * src/SDCCicode.c: fixed array add
9101 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9102 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9103 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9105 2003-01-04 <johan AT balder>
9107 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9109 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9110 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9112 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9113 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9114 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9116 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9117 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9119 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9120 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9122 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9123 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9125 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9127 * in \sdcc\as\mcs51\ changed these files in order to create an
9128 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9129 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9130 following files to include the previous two files: aslink.dsp,
9131 Makefile.aslink, Makefile.bcc, and Makefile.in.
9133 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9134 .adb instead of .cdb
9136 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9138 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9139 value from option --iram-size.
9141 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9143 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9146 2002-09-18 <wiml AT hhhh.org>
9148 * SDCClrange.h: exposed setFromRange() and setToRange()
9149 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9150 packRegsForAccUse() (bug 542397)
9151 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9152 multiple times and emitting the fetch operations more than once
9153 added aopGetUsesAcc() function to allow binary operators to
9154 fetch their operands in the correct order; made genMinus() emit
9155 compact code for X = LITERAL - Y
9157 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9158 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9159 sprintf() in line 1267.
9161 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9162 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9165 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9166 Changes to aslink (All the changes are marked with 'JCF'):
9168 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9171 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9172 area BSEG. Also moves, if possible, the DATA area down into the internal
9173 ram so more space is available.
9175 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9178 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9179 not bytes. Function summary() which creates a memory usage summary
9180 file with extension .mem. Reports of overlaping stack and small stack
9181 size. If the space for the stack is less than 16 bytes aslink trows a
9184 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9185 the 8051. Option 'y' for memory summary output file.
9187 Changes to sdcc (All the changes are marked with 'JCF'):
9189 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9191 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9192 overlaying area for it (uses RegBankUsed[4]).
9194 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9195 bank zero as used by default. By default aslink locates the stack
9196 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9197 the creation of the .mem file. Delegates the allocation of data area
9198 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9199 the begining of the stack area to aslink.
9201 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9202 glue() in SDCCglue.c creates an area for it.
9204 2002-09-03 Borut Razem <borut.razem AT siol.net>
9205 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9206 sdcc/src/pic/glue.c:
9207 introduced atexit() handler for teporay files removal in case of
9208 errors, assertions, ...
9210 2002-08-29 Borut Razem <borut.razem AT siol.net>
9211 * sdcc/support/cpp2/auto-host_vc_in.h:
9212 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9213 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9214 Maybe there is a similar problem with BORLANDC? It should be checked!
9216 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9217 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9218 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9219 was not executed, and the compiler (cl) launched a warning:
9220 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9222 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9223 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9225 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9226 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9228 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9229 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9230 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9231 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9232 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9233 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9234 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9235 - added Release configuration in VS projects
9236 - review of compiler an linker options
9237 - VC .exe files are generated in bin_vc directory, not to interfere
9238 with binaries generated from other projects (cygwin, mingw, bcc ...)
9240 * sdcc/src/yacc.dsp: added
9242 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9243 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9244 and insert the version number definitions from .version
9246 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9248 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9249 added - genarate auto-host.h using auto-host_vc_in.h as template
9252 removed from CVS, generated automatically
9254 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9255 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9257 2002-08-11 Borut Razem <borut.razem AT siol.net>
9258 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9260 2002-08-10 Borut Razem <borut.razem AT siol.net>
9261 * src/SDCCmain.c (main):
9262 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9263 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9264 The consequence was that some temporary files were not removed.
9267 unification of code in functions tempfilename() and tempfile():
9268 function tempnam() is defined in Visual Studio 6.0 and .NET
9270 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9272 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9273 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9274 - removed compiler command line option /WX: Treats all warnings as errors
9275 - update a list of source files, included into the project
9277 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9278 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9279 changed project type to Generic Project so that can be correcly converted to VS.NET project
9281 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9283 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9285 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9287 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9288 added return 0 statements after assert() to make compiler happy
9290 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9291 added newline in the def file to keep MSC compiler satisfied
9293 * sdcc/src/z80/gen.c:
9294 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9295 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9296 - solved MSC error in function aopDump()
9298 * sdcc_vc.h: define PREFIX as "\\sdcc"
9300 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9301 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9304 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9305 - Rewrote the register banking algorithm.
9306 - Added pCode live-range analysis to registers (for now, only non-used and
9307 singly-used registers optimized away)
9309 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9311 * 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.

9338 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9340 2002-03-28 Johan Knol <johan AT balder>
9342 * src/SDCCval.c: fixed bug #532436
9344 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9346 Added "char *Processor" field to the port structure.
9349 Added -p option. Allows port dependent processor to be specified.
9352 Initialized the new field char *Processor field to NULL in all ports
9355 Compiler generated registers for interrupt context saving
9356 were not getting allocated.
9358 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9361 Fixed left shift. Will promote the left side of a left shift
9362 if a) left shifting more than size of operand or b) when assigned
9363 to something size > size of left side
9365 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9367 tons of changes. Register allocation has been
9368 rewritten. Added customization for the various PICs. Flow
9369 analysis is restructured. ...
9375 Added. device.c is a PIC port hack to accomodate variations
9378 2002-03-13 Michael Hope <michaelh AT vroom>
9380 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9382 2002-03-04 johanknol <johanknol AT manik>

9386 const unsigned char arr[][2] = { { 0, 1 } };
9387 t18.c:1: error: Initializer element is not constant
9389 2002-03-04 bela <bela AT manik>
9391 * /device/include/mcs51reg.h:
9392 ds89c420 register definition update
9394 2002-03-03 <johan AT FRIJA>

9473 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9475 * sdcc/src/SDCCloop.c:
9476 Previous fix was not good. basic blocks that have "break" or "return" are
9477 not really partof a loop , but live ranges used in these blocks should
9478 be live thru the entire loop, so set partOfLoop but don't add them to
9481 2002-02-21 <johan AT FRIJA>
9483 * src/SDCCcse.c: fixed bug #514308
9485 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9488 Fixed BUG #519583. If a conditional block ended in a return/break
9489 statement inside a loop, it was not being considered part of the loop.
9491 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9493 2002-02-10 Karl Bongers <karl AT turbobit.com>
9496 Fixed up SDCDB debugger somewhat. Updated debugger/README
9497 with lots of comments and notes.
9499 * device/examples/test2.c:
9500 Fix bug, "red" variable not being initialized(compiler complained).
9502 * device/examples/Makefile, examples/test3.c:
9503 Add Makefile in device/examples folder, compiles test3.c
9504 for use as a multiple module SDCDB test case.
9506 * sim/ucsim/cmd.src/cmdset.cc:
9507 Took out debug printfs in ucsim "next" command.
9510 Karl and Johan start ucsim XA support. Most dissassembly working,
9511 about 75% emulation done(plenty of work remaining).
9513 * sim/ucsim/z80.src:
9514 Add Z80 support to ucsim, add test-ucz80 regression test,
9515 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
9516 Notice z80 compiler fails on examples/test3.c/crc code.

9530 3) added __builtin_swapw swap bytes of a short
9532 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
9533 1) handle multiple send & receives from register bank1
9534 2) ralloc can now allocate DPTR1 to some liveRanges
9536 * src/SDCCsymt.c, src/SDCCsymt.h:
9537 changes to handle multiple sends & receives
9540 added some pointer arithmetic optimization
9543 added some pointer arithmetic optimizations but not stable yet so not
9544 called from anywhere (will get this working shortly)
9546 * src/SDCCopt.c: fixed for multiple sends & receives
9549 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
9550 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
9551 set preprocessor defines (depending on options)
9553 * src/SDCCicode.c, src/SDCCicode.h:
9554 changes made to handle multiple sends & receives
9557 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
