242 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
244 Enabled VPATH feature: changed nearly all Makefiles (149 files).
245 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
247 One basic decision: e.g. src/clean.mk includes further files. In order
248 to make this work there are two solutions:
249 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
250 run configure on them. This way they can use
251 'include $(srcdir)/port-clean.mk'
252 - always include clean.mk by the Makefile at the same level. To avoid
253 that `make clean` tries to include and build Makefile.dep the
254 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
255 implemented, because now even `make uninstall` doesn't create
256 Makefile.in. clean.mk could be eliminated by pasting it in
259 * debugger/mcs51/Makefile.in: build own objects from library sources
260 (SLIB, SDCC) in current directory
262 * configure, configure.in: renamed --disable-device-lib-build in
263 --disable-device-lib; added --enable-doc, the required tools are
264 searched by configure; added result message; the toolchain for the
265 belonging ports are now only built, if the port is enabled.
267 * support/regression/*: all output is written in directory gen, because
268 the fwk and ports directories don't livet in the build tree using vpath
270 * doc/sdccman.lyx: renamed --disable-device-lib-build to
271 --disable-device-lib, added --enable-doc, added section VPATH
273 * sim/ucsim/configure.in,
274 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
275 z80 are enabled by default
277 2006-04-24 Raphael Neider <rneider AT web.de>
279 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
280 to config word, "pic14_"-prefixed some extern functions
281 (pic14_emitConfigWord): emit __config directive(s) if assignment to
282 config word has been found
283 * src/pic/device.h: added prototypes
284 * src/pic/pcode.c: added "pic14_"-prefix where needed
285 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
287 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
289 (pic14emitRegularMap): ignore config words,
290 (pic14createInterruptVect): moved generating __config directives away

547 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
548 implemented patch 1120823 Thanks to Willy De la Court (normal
549 interrupts need an interrupt number now if they are made critical),
550 and enabled nesting of critical functions though not for gbz80
551 (genCritical, genEndCritical): added functions
552 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
553 * src/z80/mappings.i: added "ei" to all mappings

559 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
560 archive with gcc 4.1 on mips and wrote the patch"
562 2006-03-16 Raphael Neider <rneider AT web.de>
564 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
565 the left operand is shorter than the result (c* = lit-c* + int),
567 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
570 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
572 * src/.version: increased version number to 2.5.5
573 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
574 linking is done manually in pic16 port's _linkEdit,
575 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
576 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
577 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
578 allocate asmop as AOP_ACC,
579 (aopForRemat): added parameter 'bool result' in function declaration,
580 (pic16_aopGet): return AOP_ACC when accessing WREG,

585 calling function in absolute addresses,
586 (genAssign): take into account AOP_ACC asmop,
587 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
588 * src/pic16/pcoderegs.c: some debug functions and lines added,

590 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
592 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
593 call to allocReg, not by manually allocating a new one,
594 (pic16_assignRegisters): now before going through the register
595 allocating functions mark all registers as free. This eliminates some
596 side effects resulting from peephole parser done earlier in the backbone
598 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

619 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
620 (aopForSym, aopOp): increment asmop.allocated if reused,
621 (freeAsmop): decrement asmop.allocated and check for zero instead of
623 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
624 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

656 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
657 which dumps before the function entry point a data byte which represents
658 the number of the local variables used by the specified function, added
659 'xinst' for initial support for Extended Instruction Support,
660 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
661 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
662 port->fun_prefix anymore (may change later),
663 (genFunction, genEndFunction): do not store/restore local registers for
664 _main (this should take care the --main-return command line option in
666 (genOr): removed some legacy pic-port instructions,
667 * src/pic16/genarith.c (genAddLit): re-enabled old code because
668 performing operations with SFR's causes data to be written more than
669 once to each SFR. Perhaps SFRs should be handled in special cases...
670 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
672 * src/pic16/main.c (_process_pragma): stack bound checking did not take
673 into account for stack starting position,
674 (struct OPTIONS pic16_optionsTable): added command line argument
675 --extended or -y for Extended Instruction Support,
676 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
677 (deassignLRs): *** perhaps the most important change, old 'for' code
678 (commented out for reference), didn't account for some registers which
679 were left marked 'not free' after a pointer operation. The change
680 reduces register usage a lot in some cases

3049 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3050 prevent compiler warning
3052 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3054 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3055 moved to level 0 and declared as static. Also they are explicit
3056 placed in access bank. This was necessery because some times they
3057 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3058 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3059 optimizations. Currently only compare to unsigned char is implemented,
3060 * src/pic16/gen.c: added fReturnIdx array,
3061 * (struct resolvedIfx) is moved to gen.h and made public,
3062 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3063 * (aopForSym): added an optimization to directly store in stack of
3064 the operand of a SEND iCode,
3065 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3066 but as registers instead (AOP_REG) using the fReturnIdx array,
3067 * (pic16_freeAsmop): remove the freed register from the
3068 _G.sregsAlloc field,
3069 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3070 a compare of 'WREG',
3071 * (pic16_popGetTempRegCond): changed function prototype, now
3072 function takes also a bitVector argument v which holds the current
3073 set of registers that are allocated for stack access by aopForSym,
3074 registers allocated in aopForSym for accessing stack symbols are not
3075 any more part of the functions usedRegs field,
3076 * (genCall): some times aopOp is called for a stack variable to be
3077 send, aopForSym might perform the push, if this is true make sure
3078 that genCall doesn't push the variable twice by testing _G.resDirect,
3079 * (genFunction): changed testing for unspecified interrupt number
3080 from 256 to INTNO_UNSPEC,
3081 * modified selection scheme of frame pointer generation. Previously
3082 if function did use local registers a frame pointer was generated,
3083 now a frame pointer is generated only if function has arguments
3084 (that need PLUSW2 register access), or has stack arguments, or the
3085 compiler is not instructed to omit the frame pointer,
3086 * (genEndFunction): before restoring local registers that were saved
3087 in the function preamble, also restore the registers that *might*
3088 have been allocated for stack access,
3089 * (genRet): removed some old comments,
3090 * (genCmp, the active (RN's) version): added a call to the
3091 pic16_genCmp_special function to perform the compare with a more
3092 robust and optimized way,
3093 * (genInline): a feature has been added in inline code generation,
3094 which allows a wildcard variable substitution when writing inline
3095 assembly. Code is incomplete and experimental therefore undocumented,
3096 * (genCast): changed order of aopOp for result and right to allow
3097 aopForSym to directly load the result if possible,
3098 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3099 perform an optimized compare on some selected special occasions,
3100 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3101 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3102 generate an IVT any more,
3103 * src/pic16/main.c (pic16_optionsTable): added command line option
3105 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3106 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3108 * src/pic16/NOTES: Raphael Neider added in list of active developers
3109 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3110 jumptable_end to prevent bug #,
3111 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3112 inCond and outCond fields,
3113 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3114 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3115 turn off register spilling,
3116 * (packRegsForOneUse): synced with other ports' versions although it
3117 is not used currently,
3118 * (pic16_packRegisters): added an optimization while reading
3119 structure bitfields, some registers may be saved (malloc code is
3120 decreased by 80 bytes)
3122 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3124 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3125 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3126 this can be optimized more?
3128 2005-03-10 Raphael Neider <rneider AT web.de>
3130 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3131 genNearPointerGet): (hopefully) fixed access to bitfields via
3132 pointers (p->bitN = x; and x = p->bitN; failed)

3458 access stack and frame pointers. They are initially assigned to
3459 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
3460 accessing SFRs. Updated all occurences of modification of stack or
3461 frame pointer in gen.c and pcode.c,
3462 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
3463 assigning of a literal value to pointers,

3767 generated for switch statements. For now you need to set the
3768 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3769 Now 4 algorithms for mcs51 jumptable generation are used:
3770 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3804 * added libc directory. The current version of LibC contains string
3805 functions, ctype functions and macros and some functions of the
3806 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3807 be extensively tested in the future. Standard disclaimer here.

3820 * (pic16_storeForReturn): optimized return of 0,
3821 * (genCmp): experimental code for new genCmp which uses PIC18's
3822 special compare&skip instructions. Initial tests fail some times
3823 with variables grater than 1 byte in size, so new code is disabled,
3824 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3826 * (genCast): began a fix to optimize the casting of a bit to another
3827 bit, now assigning a bitfield to another bitfield will fail, sorry,

3841 registers when it shouldn't,
3842 * src/pic16/ralloc.c (allocReg): add preliminary support for
3843 supporting a limited set of temporary registers,
3845 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6853 loaded with the linker search paths (-L arguments) and the libraries
6854 to be linked with the current source (-l arguments). Changes
6855 currently will affect only the pic16 port.
6856 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6857 include path the port specific paths and port specific libraries,
6858 * gplink command now contains the $3 argument,
6859 * src/pic16/device.h,

6876 Documenting changes from previous commits.
6877 * configure.in (version 1.56),
6878 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6879 when generating output files to configure the pic16 library,
6880 but now I've commented it out, since gputils aren't installed in the
6881 SF compile farm, so library won't compile
6883 * device/lib/Makefile.in (version 1.56): initially I've added in
6884 target 'all' the prerequestive 'model-pic16' so it compiled the
6885 pic16 library, but now I've commented it out for the same reasons
6887 * added targets 'model-pic16' and 'objects-pic16' to compile the
6889 * added target 'port-specific-objects-pic16' to handle the
6890 generated libraries and copy them into the build/ directory
6891 * added target 'clean-intermediate-pic16' to clean intermediate
6892 files into pic16 directory
6893 * in target 'installdirs' added line to create directory pic16 in

6915 option so that it actually works. Made it specific to the z80, since
6916 the gbz80 doesn't have these kinds of I/O ports.
6918 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7032 * src/pic16/ralloc.c: the register allocator can now reuse local
7033 function symbols for another function. This saves register usage.

7140 LEFT_OP (left shift)
7142 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7144 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7145 (default behaviour).
7147 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7149 A python script to validate compiler diagnostic messages. It can be
7150 used to verify that sdcc complains about bad c source code and
7151 gives a good location of the error.
7152 * support/valdiag/Makefile,
7153 * support/valdiag/valdiag.py,
7154 * support/valdiag/tests/*

7171 Bug reported from Jesus Calvino-Fraga
7173 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7175 * sdcc.spec: updated
7176 * device/include/Makefile.in: don't install CVS directories
7177 * device/lib/Makefile.in: added removal of CVS directories after install
7178 * doc/Makefile: fixed install, added local_icons
7179 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7180 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7181 * src/ds390/gen.c (genRightShift): fixed bug #870788
7182 * src/SDCCast.c (decorateType): fixed bug #870781
7184 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7186 PIC16 port related changes:
7187 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7188 added variable stackPos,
7190 * gen.c: genCall, assignResultValue: added support for
7191 pushing/retrieving function parameters to/from stack,
7192 genFunction,genEndFunction: setup stack frame for the
7194 genAddrOf: will be changed according to bug 863624
7196 * added files genutils.c and genutils.h which contain gen*
7197 debugged and optimised functions extracted from gen.c
7199 * glue.c: added variable 'externs' which holds extern symbols,
7200 pic16emitRegularMap: is modified to properly handle relocatable
7201 symbols under the new scheme,
7202 pic16createInterruptVect: is modified
7203 pic16printPublics: is modified to emit 'global' assembler directives,
7204 added pic16_printExterns to print extern symbols,
7205 pic16glue: initializes stack/frame pointer in the beginning of
7206 the assembly output. Temporary hack, will be corrected later,
7207 because gplink yet does not support stack and SDCC does not
7208 yet support a type of crt0.o object to create the final binary.
7210 * Removed many lines that contain 8051 legacy code.
7211 * The code is finally placed under a 'code' directive.
7212 * Added port specific options.
7214 * _process_pragma: simplified since now we do not need *special*
7215 include file to define SFR registers. But a separate header
7216 will be needed. This will be developed later.
7217 * _pic16_parseOptions: added, parses port specific options:
7218 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7219 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7220 --preplace-udata-with=
7222 * _pic16_setDefaultOptions: modified to initialize section names,
7223 but hack is temporarly out of order since it needs improvement.
7224 * _pic16_genAssemblerPreamble: configuration words are emitted by
7225 their address instead of their name. This part is incomplete and
7226 supports only the 18Fxx2 devices. Other devices will emit an error
7227 during assembly since they do not contain the same set of config
7229 * _pic16_genIVT: is modified,
7231 * pcode.c: added definitions for some hardware registers that are needed
7233 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7234 All PCI entries are updated. Now LFSR is supported.
7235 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7236 * added pic16_newpCodeOpLit2 to support instructions with
7237 two literal arguments
7238 * pic16_pCode2str: corrected code that emits assembler instructions
7239 with two literal operands and those that have an access bit modifier
7240 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7241 this fixes a bug which caused some labels to be lost, when an
7242 assembler directive was added, i.e. banksel,
7243 * pic16_FixRegisterBanking: improved logic that causes the insertion
7245 * InlineFunction: functions that are called once, are not any more
7246 inlined. This can be a port option in the future,
7248 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7250 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7251 hold the corresponding uninitialized symbols,
7252 * pic16_allocProcessorRegister: registers have explicit marked the
7254 * pic16_allocInternalRegister: registers are explicit marked as
7256 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7257 processing list, so bit registers were lost,
7260 * ralloc.h: added field 'accessBank' and original symbol operand
7261 in register definition,
7262 * removed the field isMapped from register definition,
7264 ** Several functions have been removed from various sources:
7265 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7266 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7267 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7268 pic16_assignRelocatableRegisters
7270 ** others have been introduced:
7271 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7272 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7274 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7276 * support/scripts/inc2h.pl: changed definition of BIT_AT
7277 to emit 'sbit at' instead of 'bit at'. This was a request.
7279 PIC16 port related preliminary changes:
7280 * gen.c: prefixed function popRegFromString with
7281 pic16_ and all references to it corrected
7282 * pcode.c: all pic16_pc_* hardware registers prefixed
7283 with underscore (_),
7284 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7285 * ralloc.c: newReg(): when register is REG_SFR then
7286 set address to rIdx,
7287 pic16_allocProcessorRegister(): marks register wasUsed=0
7288 pic16_writeUsedRegs(): added a call to assign processor
7289 registers via pic16_assignFixedRegisters
7291 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7293 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7294 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7295 variables in unused register banks. Also the SSEG is placed
7296 wherever there is enough space for it, and IDATA can be anywhere
7297 in internal RAM. For now compile using -Wl-Y[stack_size].
7298 The mem file is different for this option as well, since it
7299 makes no sense of talking about DSEG lenght.
7301 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7303 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7304 in certain cases, e.g. when ROM assignment, patch provided
7305 from Albert den Haan.
7307 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8309 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8310 fetching of the pointer
8311 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8312 copied from genNearPointerSet()
8313 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8314 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8315 If they pop r0/r1 they must be called in the opposite order than aopOp().
8316 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8317 (resp. --stack-auto), prepared for --xstack

8330 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8331 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8332 type for bits was changed. It resulted in bit variables becoming
8333 global, which is not permitted in PIC 14 assembly output.
8335 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8337 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8350 A few small changes that speed up the peephole optimizer.
8354 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8356 Try to make the peephole optimizer smarter by maintaining
8357 an association between the assembly source code and the
8358 iCodes that originated them. Put this information to use
8359 with a new peephole rule condition "notVolatile" so that
8360 the rules can be aggressive yet still safe.
8365 * src/mcs51/peeph.def
8367 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8371 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8372 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8373 if the left or right operand symbols have the accuse flag set.
8375 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8377 Changed the type of the result of the ! (NOT) operator to char;
8378 previously it returned the same type as the source. This allows
8379 us to eliminate all the genFloatNot functions (all of its target
8380 implementations were very buggy) since !float can use the same
8383 * src/SDCCicode.c (ast2iCode): ! returns char

8390 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8392 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8393 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8394 during interrupts. Ensure WSAVE is located at a shared bank address.
8395 2. Fixed page selection in some places
8396 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8397 the registers name strings.
8398 4. Fixed "signed / unsigned compare" compiler warnings.
8399 5. The PIC port manages its own allocation of the general purpose
8400 registers, but makes no attempt to reuse them. As a result when
8401 compiling it soon runs out of general purpose registers. Some
8402 additional code was added to the files pcode.c and device.c to walk
8403 through the function call tree and rename the registers so that they
8413 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8414 genPlus() & genMinus() when the result is the same as left or right

8420 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8422 Made bitfield a distinct type from bit so that bitfields
8423 convert as per ANSI C and bits retain their traditional
8424 boolean style behaviour. Implemented bitfield support in
8432 * src/ds390/gen.c: bit v bitfield split
8433 * src/z80/gen.c: New support for bitfields
8434 * support/regression/tests/bitfields.c: reenabled z80,
8437 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8439 Rules 246.x, 247.x relate to bitfields, the others speed up
8440 access to xdata mapped I/O devices.
8442 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8444 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8446 Cleaned up genPackBits and genUnpackBits and added two helper
8447 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8448 for literal assignments in genPackBits (thanks to Frieder for
8454 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8456 Fixed bug #748310 (pointer to function type mishandled when the
8457 function name is omitted). Also fixed a SIGSEGV when a function
8458 attribute (reentrant, etc) is used on a non-function or on a
8459 function but misplaced before the parameter list.
8461 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8463 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8464 * support/Util/SDCCerr.h,
8465 * support/Util/SDCCerr.c: Added func attr misuse error msg

8486 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8488 Made the constant following the "interrupt" keyword optional. If
8489 omitted, the function will not automatically be given an entry
8490 in the interrupt vector table (similar to #pragma NOIV, but
8491 less syntacticly kludgy). The interrupt number is also now
8492 range checked. Also fixed a bug in the high order bit example

8506 * src/SDCCicode.c (operandOperation): rewritten some ops
8507 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8508 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8510 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8511 be re-activated by defining REDUCE_LITERALS)
8512 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8513 unsigned, but are signed by default
8514 * src/SDCCval.c (constVal): rearranged
8515 * src/SDCCval.c (valMod): preliminary fix
8516 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9022 added if/endif conditional macros to remove options help
9023 messages from optionsTable when a port is not configured, added
9024 support for the PIc16 port in the ports table, when executing
9025 the compiler with no port specified on command line, a default
9026 port is selected with the new macro DEFAULT_PORT which is
9027 defined in port.h, in setDefaultOptions() linkOptions is removed
9028 from initialization assignment, since now it is a set,
9029 parseCmdLine uses setParseWithComma for linkOptions, in
9030 linkEdit() linkOptions are accessed with new function indexSet()
9031 which returns the i'th item of a set variable. See SDCCset.c, in
9032 linkEdit() when calling buildCmdLine(), added linkOptions as
9033 last argument. Now users can pass arguments to gplink via the
9034 -Wl option, main() uses pic16glue() to glue up pic16 programs

9048 gpasm complaining and test the linkage with gplink, _linkCmd and
9049 _asmCmd changed to be more gplink and gpasm friendly
9050 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9051 produced an error when parsed, peep rule 12 is added to utilize
9052 movff, but it is commented out since the pCode does not support
9053 yet a command with 2 address arguments
9055 2003-05-18 <johan AT balder>
9057 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9077 on entry now. Add tbreak. Other enhancements and fixes for use
9080 2003-05-12 Borut Razem <borut.razem AT siol.net>
9082 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9084 2003-05-11 Borut Razem <borut.razem AT siol.net>
9086 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9087 the path of bin directory, so that PATH is the only env. variable, which has to be set
9088 in case of standard installation.

10118 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10120 * in \sdcc\as\mcs51\ changed these files in order to create an
10121 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10122 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10123 following files to include the previous two files: aslink.dsp,
10124 Makefile.aslink, Makefile.bcc, and Makefile.in.
10126 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10127 .adb instead of .cdb
10129 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10131 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10132 value from option --iram-size.
10134 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10136 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10139 2002-09-18 <wiml AT hhhh.org>
10141 * SDCClrange.h: exposed setFromRange() and setToRange()
10142 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10143 packRegsForAccUse() (bug 542397)
10144 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10145 multiple times and emitting the fetch operations more than once
10146 added aopGetUsesAcc() function to allow binary operators to
10147 fetch their operands in the correct order; made genMinus() emit
10148 compact code for X = LITERAL - Y
10150 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10151 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10152 sprintf() in line 1267.
10154 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10155 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10158 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10159 Changes to aslink (All the changes are marked with 'JCF'):
10161 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10164 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10165 area BSEG. Also moves, if possible, the DATA area down into the internal
10166 ram so more space is available.
10168 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10171 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10172 not bytes. Function summary() which creates a memory usage summary
10173 file with extension .mem. Reports of overlaping stack and small stack
10174 size. If the space for the stack is less than 16 bytes aslink trows a
10177 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10178 the 8051. Option 'y' for memory summary output file.
10180 Changes to sdcc (All the changes are marked with 'JCF'):
10182 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10184 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10185 overlaying area for it (uses RegBankUsed[4]).
10187 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10188 bank zero as used by default. By default aslink locates the stack
10189 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10190 the creation of the .mem file. Delegates the allocation of data area
10191 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10192 the begining of the stack area to aslink.
10194 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10195 glue() in SDCCglue.c creates an area for it.
10197 2002-09-03 Borut Razem <borut.razem AT siol.net>
10198 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10199 sdcc/src/pic/glue.c:
10200 introduced atexit() handler for teporay files removal in case of
10201 errors, assertions, ...
10203 2002-08-29 Borut Razem <borut.razem AT siol.net>
10204 * sdcc/support/cpp2/auto-host_vc_in.h:
10205 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10206 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10207 Maybe there is a similar problem with BORLANDC? It should be checked!
10209 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10210 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10211 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10212 was not executed, and the compiler (cl) launched a warning:
10213 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10215 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10216 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10218 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10219 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10221 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10222 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10223 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10224 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10225 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10226 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10227 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10228 - added Release configuration in VS projects
10229 - review of compiler an linker options
10230 - VC .exe files are generated in bin_vc directory, not to interfere
10231 with binaries generated from other projects (cygwin, mingw, bcc ...)
10233 * sdcc/src/yacc.dsp: added
10235 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10236 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10237 and insert the version number definitions from .version
10239 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10241 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10242 added - genarate auto-host.h using auto-host_vc_in.h as template
10245 removed from CVS, generated automatically
10247 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10248 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10250 2002-08-11 Borut Razem <borut.razem AT siol.net>
10251 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10253 2002-08-10 Borut Razem <borut.razem AT siol.net>
10254 * src/SDCCmain.c (main):
10255 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10256 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10257 The consequence was that some temporary files were not removed.
10260 unification of code in functions tempfilename() and tempfile():
10261 function tempnam() is defined in Visual Studio 6.0 and .NET
10263 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10265 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10266 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10267 - removed compiler command line option /WX: Treats all warnings as errors
10268 - update a list of source files, included into the project
10270 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10271 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10272 changed project type to Generic Project so that can be correcly converted to VS.NET project
10274 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10276 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10278 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10280 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10281 added return 0 statements after assert() to make compiler happy
10283 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10284 added newline in the def file to keep MSC compiler satisfied
10286 * sdcc/src/z80/gen.c:
10287 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10288 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10289 - solved MSC error in function aopDump()
10291 * sdcc_vc.h: define PREFIX as "\\sdcc"
10293 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

10297 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10298 - Rewrote the register banking algorithm.
10299 - Added pCode live-range analysis to registers (for now, only non-used and
10300 singly-used registers optimized away)
10302 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10304 * 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.

10342 Added -p option. Allows port dependent processor to be specified.
10345 Initialized the new field char *Processor field to NULL in all ports
10348 Compiler generated registers for interrupt context saving
10349 were not getting allocated.
10351 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10354 Fixed left shift. Will promote the left side of a left shift
10355 if a) left shifting more than size of operand or b) when assigned
10356 to something size > size of left side
10358 2002-03-14 Scott Dattalo <scott AT dattalo.com>

10362 analysis is restructured. ...
10364 * src/pic/device.h:
10367 * src/pic/device.c:
10368 Added. device.c is a PIC port hack to accomodate variations

10373 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10375 2002-03-04 johanknol <johanknol AT manik>
10377 * /src/SDCCval.c: fixed
10379 const unsigned char arr[][2] = { { 0, 1 } };
