224 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
226 Enabled VPATH feature: changed nearly all Makefiles (149 files).
227 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
229 One basic decision: e.g. src/clean.mk includes further files. In order
230 to make this work there are two solutions:
231 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
232 run configure on them. This way they can use
233 'include $(srcdir)/port-clean.mk'
234 - always include clean.mk by the Makefile at the same level. To avoid
235 that `make clean` tries to include and build Makefile.dep the
236 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
237 implemented, because now even `make uninstall` doesn't create
238 Makefile.in. clean.mk could be eliminated by pasting it in
241 * debugger/mcs51/Makefile.in: build own objects from library sources
242 (SLIB, SDCC) in current directory
244 * configure, configure.in: renamed --disable-device-lib-build in
245 --disable-device-lib; added --enable-doc, the required tools are
246 searched by configure; added result message; the toolchain for the
247 belonging ports are now only built, if the port is enabled.
249 * support/regression/*: all output is written in directory gen, because
250 the fwk and ports directories don't livet in the build tree using vpath
252 * doc/sdccman.lyx: renamed --disable-device-lib-build to
253 --disable-device-lib, added --enable-doc, added section VPATH
255 * sim/ucsim/configure.in,
256 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
257 z80 are enabled by default
259 2006-04-24 Raphael Neider <rneider AT web.de>
261 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
262 to config word, "pic14_"-prefixed some extern functions
263 (pic14_emitConfigWord): emit __config directive(s) if assignment to
264 config word has been found
265 * src/pic/device.h: added prototypes
266 * src/pic/pcode.c: added "pic14_"-prefix where needed
267 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
269 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

283 fixes #1469504 and #1474602,
284 (pCodeRegOptimizeRegUsage): fixed typo in comment

530 implemented patch 1120823 Thanks to Willy De la Court (normal
531 interrupts need an interrupt number now if they are made critical),
532 and enabled nesting of critical functions though not for gbz80
533 (genCritical, genEndCritical): added functions
534 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
535 * src/z80/mappings.i: added "ei" to all mappings

542 archive with gcc 4.1 on mips and wrote the patch"
544 2006-03-16 Raphael Neider <rneider AT web.de>
546 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
547 the left operand is shorter than the result (c* = lit-c* + int),
549 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
552 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
554 * src/.version: increased version number to 2.5.5
555 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
556 linking is done manually in pic16 port's _linkEdit,
557 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
558 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
559 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
560 allocate asmop as AOP_ACC,
561 (aopForRemat): added parameter 'bool result' in function declaration,
562 (pic16_aopGet): return AOP_ACC when accessing WREG,

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

572 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
574 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
575 call to allocReg, not by manually allocating a new one,
576 (pic16_assignRegisters): now before going through the register
577 allocating functions mark all registers as free. This eliminates some
578 side effects resulting from peephole parser done earlier in the backbone
580 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
582 * src/SDCCicode.c (geniCodeLogic),

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

630 2006-03-06 Borut Razem <borut.razem AT siol.net>
632 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
633 made the linker quiet
635 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
637 * src/pic16/gen.c (genPcall): fixed bug #1443644
638 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
639 which dumps before the function entry point a data byte which represents
640 the number of the local variables used by the specified function, added
641 'xinst' for initial support for Extended Instruction Support,
642 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
643 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
644 port->fun_prefix anymore (may change later),
645 (genFunction, genEndFunction): do not store/restore local registers for
646 _main (this should take care the --main-return command line option in
648 (genOr): removed some legacy pic-port instructions,
649 * src/pic16/genarith.c (genAddLit): re-enabled old code because
650 performing operations with SFR's causes data to be written more than
651 once to each SFR. Perhaps SFRs should be handled in special cases...
652 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
654 * src/pic16/main.c (_process_pragma): stack bound checking did not take
655 into account for stack starting position,
656 (struct OPTIONS pic16_optionsTable): added command line argument
657 --extended or -y for Extended Instruction Support,
658 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
659 (deassignLRs): *** perhaps the most important change, old 'for' code
660 (commented out for reference), didn't account for some registers which
661 were left marked 'not free' after a pointer operation. The change
662 reduces register usage a lot in some cases

3043 * (struct resolvedIfx) is moved to gen.h and made public,
3044 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3045 * (aopForSym): added an optimization to directly store in stack of
3046 the operand of a SEND iCode,
3047 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3048 but as registers instead (AOP_REG) using the fReturnIdx array,
3049 * (pic16_freeAsmop): remove the freed register from the
3050 _G.sregsAlloc field,
3051 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3052 a compare of 'WREG',
3053 * (pic16_popGetTempRegCond): changed function prototype, now
3054 function takes also a bitVector argument v which holds the current
3055 set of registers that are allocated for stack access by aopForSym,
3056 registers allocated in aopForSym for accessing stack symbols are not
3057 any more part of the functions usedRegs field,
3058 * (genCall): some times aopOp is called for a stack variable to be
3059 send, aopForSym might perform the push, if this is true make sure
3060 that genCall doesn't push the variable twice by testing _G.resDirect,
3061 * (genFunction): changed testing for unspecified interrupt number
3062 from 256 to INTNO_UNSPEC,
3063 * modified selection scheme of frame pointer generation. Previously
3064 if function did use local registers a frame pointer was generated,
3065 now a frame pointer is generated only if function has arguments
3066 (that need PLUSW2 register access), or has stack arguments, or the
3067 compiler is not instructed to omit the frame pointer,
3068 * (genEndFunction): before restoring local registers that were saved
3069 in the function preamble, also restore the registers that *might*
3070 have been allocated for stack access,
3071 * (genRet): removed some old comments,
3072 * (genCmp, the active (RN's) version): added a call to the
3073 pic16_genCmp_special function to perform the compare with a more
3074 robust and optimized way,
3075 * (genInline): a feature has been added in inline code generation,
3076 which allows a wildcard variable substitution when writing inline
3077 assembly. Code is incomplete and experimental therefore undocumented,
3078 * (genCast): changed order of aopOp for result and right to allow
3079 aopForSym to directly load the result if possible,
3080 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3081 perform an optimized compare on some selected special occasions,
3082 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3083 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3084 generate an IVT any more,
3085 * src/pic16/main.c (pic16_optionsTable): added command line option
3087 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3088 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3090 * src/pic16/NOTES: Raphael Neider added in list of active developers
3091 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3092 jumptable_end to prevent bug #,
3093 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3094 inCond and outCond fields,
3095 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3096 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3097 turn off register spilling,
3098 * (packRegsForOneUse): synced with other ports' versions although it
3099 is not used currently,
3100 * (pic16_packRegisters): added an optimization while reading
3101 structure bitfields, some registers may be saved (malloc code is
3102 decreased by 80 bytes)
3104 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3106 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3107 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3108 this can be optimized more?
3110 2005-03-10 Raphael Neider <rneider AT web.de>
3112 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3113 genNearPointerGet): (hopefully) fixed access to bitfields via
3114 pointers (p->bitN = x; and x = p->bitN; failed)

3440 access stack and frame pointers. They are initially assigned to
3441 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
3442 accessing SFRs. Updated all occurences of modification of stack or
3443 frame pointer in gen.c and pcode.c,

3748 Adding support for replacing ljmps with sjmps in jumptables
3749 generated for switch statements. For now you need to set the
3750 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3751 Now 4 algorithms for mcs51 jumptable generation are used:
3752 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3753 addresses loaded pc-relative for up to 112 cases and stack-pushing
3754 target addresses loaded with offset from dptr for up to 256 cases.

3787 functions, ctype functions and macros and some functions of the
3788 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3789 be extensively tested in the future. Standard disclaimer here.

3803 * (genCmp): experimental code for new genCmp which uses PIC18's
3804 special compare&skip instructions. Initial tests fail some times
3805 with variables grater than 1 byte in size, so new code is disabled,
3806 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3808 * (genCast): began a fix to optimize the casting of a bit to another
3809 bit, now assigning a bitfield to another bitfield will fail, sorry,

3824 * src/pic16/ralloc.c (allocReg): add preliminary support for
3825 supporting a limited set of temporary registers,

6834 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6835 loaded with the linker search paths (-L arguments) and the libraries
6836 to be linked with the current source (-l arguments). Changes
6837 currently will affect only the pic16 port.
6838 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6839 include path the port specific paths and port specific libraries,
6840 * gplink command now contains the $3 argument,
6841 * src/pic16/device.h,
6842 * src/pic16/device.c,: structure PIC_device is made public and
6843 renamed to PIC16_device, the same for variable Pics which is renamed

6858 Documenting changes from previous commits.
6859 * configure.in (version 1.56),
6860 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6861 when generating output files to configure the pic16 library,
6862 but now I've commented it out, since gputils aren't installed in the
6863 SF compile farm, so library won't compile
6865 * device/lib/Makefile.in (version 1.56): initially I've added in
6866 target 'all' the prerequestive 'model-pic16' so it compiled the
6867 pic16 library, but now I've commented it out for the same reasons
6869 * added targets 'model-pic16' and 'objects-pic16' to compile the
6871 * added target 'port-specific-objects-pic16' to handle the
6872 generated libraries and copy them into the build/ directory
6873 * added target 'clean-intermediate-pic16' to clean intermediate
6874 files into pic16 directory
6875 * in target 'installdirs' added line to create directory pic16 in

6897 option so that it actually works. Made it specific to the z80, since
6898 the gbz80 doesn't have these kinds of I/O ports.
6900 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7124 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7126 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7127 (default behaviour).
7129 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7131 A python script to validate compiler diagnostic messages. It can be
7132 used to verify that sdcc complains about bad c source code and
7133 gives a good location of the error.
7134 * support/valdiag/Makefile,
7135 * support/valdiag/valdiag.py,
7136 * support/valdiag/tests/*

7153 Bug reported from Jesus Calvino-Fraga
7155 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7157 * sdcc.spec: updated
7158 * device/include/Makefile.in: don't install CVS directories
7159 * device/lib/Makefile.in: added removal of CVS directories after install
7160 * doc/Makefile: fixed install, added local_icons
7161 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7162 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7163 * src/ds390/gen.c (genRightShift): fixed bug #870788
7164 * src/SDCCast.c (decorateType): fixed bug #870781
7166 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7168 PIC16 port related changes:
7169 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7170 added variable stackPos,
7172 * gen.c: genCall, assignResultValue: added support for
7173 pushing/retrieving function parameters to/from stack,
7174 genFunction,genEndFunction: setup stack frame for the
7176 genAddrOf: will be changed according to bug 863624
7178 * added files genutils.c and genutils.h which contain gen*
7179 debugged and optimised functions extracted from gen.c
7181 * glue.c: added variable 'externs' which holds extern symbols,
7182 pic16emitRegularMap: is modified to properly handle relocatable
7183 symbols under the new scheme,
7184 pic16createInterruptVect: is modified
7185 pic16printPublics: is modified to emit 'global' assembler directives,
7186 added pic16_printExterns to print extern symbols,
7187 pic16glue: initializes stack/frame pointer in the beginning of
7188 the assembly output. Temporary hack, will be corrected later,
7189 because gplink yet does not support stack and SDCC does not
7190 yet support a type of crt0.o object to create the final binary.
7192 * Removed many lines that contain 8051 legacy code.
7193 * The code is finally placed under a 'code' directive.
7194 * Added port specific options.
7196 * _process_pragma: simplified since now we do not need *special*
7197 include file to define SFR registers. But a separate header
7198 will be needed. This will be developed later.
7199 * _pic16_parseOptions: added, parses port specific options:
7200 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7201 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7202 --preplace-udata-with=
7204 * _pic16_setDefaultOptions: modified to initialize section names,
7205 but hack is temporarly out of order since it needs improvement.
7206 * _pic16_genAssemblerPreamble: configuration words are emitted by
7207 their address instead of their name. This part is incomplete and
7208 supports only the 18Fxx2 devices. Other devices will emit an error
7209 during assembly since they do not contain the same set of config
7211 * _pic16_genIVT: is modified,
7213 * pcode.c: added definitions for some hardware registers that are needed
7215 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7216 All PCI entries are updated. Now LFSR is supported.
7217 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7218 * added pic16_newpCodeOpLit2 to support instructions with
7219 two literal arguments
7220 * pic16_pCode2str: corrected code that emits assembler instructions
7221 with two literal operands and those that have an access bit modifier
7222 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7223 this fixes a bug which caused some labels to be lost, when an
7224 assembler directive was added, i.e. banksel,
7225 * pic16_FixRegisterBanking: improved logic that causes the insertion
7227 * InlineFunction: functions that are called once, are not any more
7228 inlined. This can be a port option in the future,
7230 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7232 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7233 hold the corresponding uninitialized symbols,
7234 * pic16_allocProcessorRegister: registers have explicit marked the
7236 * pic16_allocInternalRegister: registers are explicit marked as
7238 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7239 processing list, so bit registers were lost,
7242 * ralloc.h: added field 'accessBank' and original symbol operand
7243 in register definition,
7244 * removed the field isMapped from register definition,
7246 ** Several functions have been removed from various sources:
7247 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7248 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7249 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7250 pic16_assignRelocatableRegisters
7252 ** others have been introduced:
7253 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7254 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7256 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7258 * support/scripts/inc2h.pl: changed definition of BIT_AT
7259 to emit 'sbit at' instead of 'bit at'. This was a request.
7261 PIC16 port related preliminary changes:
7262 * gen.c: prefixed function popRegFromString with
7263 pic16_ and all references to it corrected
7264 * pcode.c: all pic16_pc_* hardware registers prefixed
7265 with underscore (_),
7266 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7267 * ralloc.c: newReg(): when register is REG_SFR then
7268 set address to rIdx,
7269 pic16_allocProcessorRegister(): marks register wasUsed=0
7270 pic16_writeUsedRegs(): added a call to assign processor
7271 registers via pic16_assignFixedRegisters
7273 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7275 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7276 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7277 variables in unused register banks. Also the SSEG is placed
7278 wherever there is enough space for it, and IDATA can be anywhere
7279 in internal RAM. For now compile using -Wl-Y[stack_size].
7280 The mem file is different for this option as well, since it
7281 makes no sense of talking about DSEG lenght.
7283 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7285 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7286 in certain cases, e.g. when ROM assignment, patch provided
7287 from Albert den Haan.
7289 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8291 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8292 fetching of the pointer
8293 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8294 copied from genNearPointerSet()
8295 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8296 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8297 If they pop r0/r1 they must be called in the opposite order than aopOp().
8298 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8299 (resp. --stack-auto), prepared for --xstack

8310 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8312 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8313 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8314 type for bits was changed. It resulted in bit variables becoming
8315 global, which is not permitted in PIC 14 assembly output.
8317 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8319 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8332 A few small changes that speed up the peephole optimizer.
8336 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8338 Try to make the peephole optimizer smarter by maintaining
8339 an association between the assembly source code and the
8340 iCodes that originated them. Put this information to use
8341 with a new peephole rule condition "notVolatile" so that
8342 the rules can be aggressive yet still safe.
8347 * src/mcs51/peeph.def
8349 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8353 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8354 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8355 if the left or right operand symbols have the accuse flag set.
8357 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8359 Changed the type of the result of the ! (NOT) operator to char;
8360 previously it returned the same type as the source. This allows
8361 us to eliminate all the genFloatNot functions (all of its target
8362 implementations were very buggy) since !float can use the same
8365 * src/SDCCicode.c (ast2iCode): ! returns char

8367 * src/ds390/gen.c (genNot, genNotFloat),
8368 * src/z80/gen.c (genNot, genNotFloat),
8369 * src/pic/gen.c (genNot, genNotFloat),

8372 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8374 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8375 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8376 during interrupts. Ensure WSAVE is located at a shared bank address.
8377 2. Fixed page selection in some places
8378 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8379 the registers name strings.
8380 4. Fixed "signed / unsigned compare" compiler warnings.
8381 5. The PIC port manages its own allocation of the general purpose
8382 registers, but makes no attempt to reuse them. As a result when
8383 compiling it soon runs out of general purpose registers. Some
8384 additional code was added to the files pcode.c and device.c to walk
8385 through the function call tree and rename the registers so that they
8395 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8396 genPlus() & genMinus() when the result is the same as left or right
8398 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8402 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8404 Made bitfield a distinct type from bit so that bitfields
8405 convert as per ANSI C and bits retain their traditional
8406 boolean style behaviour. Implemented bitfield support in
8414 * src/ds390/gen.c: bit v bitfield split
8415 * src/z80/gen.c: New support for bitfields
8416 * support/regression/tests/bitfields.c: reenabled z80,
8419 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8421 Rules 246.x, 247.x relate to bitfields, the others speed up
8422 access to xdata mapped I/O devices.
8424 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8426 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8428 Cleaned up genPackBits and genUnpackBits and added two helper
8429 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8430 for literal assignments in genPackBits (thanks to Frieder for
8436 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8438 Fixed bug #748310 (pointer to function type mishandled when the
8439 function name is omitted). Also fixed a SIGSEGV when a function
8440 attribute (reentrant, etc) is used on a non-function or on a
8441 function but misplaced before the parameter list.
8443 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8445 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8446 * support/Util/SDCCerr.h,
8447 * support/Util/SDCCerr.c: Added func attr misuse error msg

8468 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8470 Made the constant following the "interrupt" keyword optional. If
8471 omitted, the function will not automatically be given an entry
8472 in the interrupt vector table (similar to #pragma NOIV, but
8473 less syntacticly kludgy). The interrupt number is also now
8474 range checked. Also fixed a bug in the high order bit example

8488 * src/SDCCicode.c (operandOperation): rewritten some ops
8489 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8490 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8492 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8493 be re-activated by defining REDUCE_LITERALS)
8494 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8495 unsigned, but are signed by default
8496 * src/SDCCval.c (constVal): rearranged
8497 * src/SDCCval.c (valMod): preliminary fix
8498 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8540 constants are unsigned; added recognition of "u" flag for unsigned
8541 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8542 * src/SDCCval.c (valDiv, valMod): fixed signdness
8543 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8544 signedness of modulo, left and right shift

9004 added if/endif conditional macros to remove options help
9005 messages from optionsTable when a port is not configured, added
9006 support for the PIc16 port in the ports table, when executing
9007 the compiler with no port specified on command line, a default
9008 port is selected with the new macro DEFAULT_PORT which is
9009 defined in port.h, in setDefaultOptions() linkOptions is removed
9010 from initialization assignment, since now it is a set,
9011 parseCmdLine uses setParseWithComma for linkOptions, in
9012 linkEdit() linkOptions are accessed with new function indexSet()
9013 which returns the i'th item of a set variable. See SDCCset.c, in
9014 linkEdit() when calling buildCmdLine(), added linkOptions as
9015 last argument. Now users can pass arguments to gplink via the
9016 -Wl option, main() uses pic16glue() to glue up pic16 programs

9030 gpasm complaining and test the linkage with gplink, _linkCmd and
9031 _asmCmd changed to be more gplink and gpasm friendly
9032 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9033 produced an error when parsed, peep rule 12 is added to utilize
9034 movff, but it is commented out since the pCode does not support
9035 yet a command with 2 address arguments
9037 2003-05-18 <johan AT balder>
9039 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9066 2003-05-11 Borut Razem <borut.razem AT siol.net>
9068 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10098 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10100 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10102 * in \sdcc\as\mcs51\ changed these files in order to create an
10103 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10104 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10105 following files to include the previous two files: aslink.dsp,
10106 Makefile.aslink, Makefile.bcc, and Makefile.in.
10108 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10109 .adb instead of .cdb
10111 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10113 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10114 value from option --iram-size.
10116 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10118 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10121 2002-09-18 <wiml AT hhhh.org>
10123 * SDCClrange.h: exposed setFromRange() and setToRange()
10124 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10125 packRegsForAccUse() (bug 542397)
10126 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10127 multiple times and emitting the fetch operations more than once
10128 added aopGetUsesAcc() function to allow binary operators to
10129 fetch their operands in the correct order; made genMinus() emit
10130 compact code for X = LITERAL - Y
10132 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10133 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10134 sprintf() in line 1267.
10136 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10137 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10140 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10141 Changes to aslink (All the changes are marked with 'JCF'):
10143 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10146 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10147 area BSEG. Also moves, if possible, the DATA area down into the internal
10148 ram so more space is available.
10150 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10153 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10154 not bytes. Function summary() which creates a memory usage summary
10155 file with extension .mem. Reports of overlaping stack and small stack
10156 size. If the space for the stack is less than 16 bytes aslink trows a
10159 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10160 the 8051. Option 'y' for memory summary output file.
10162 Changes to sdcc (All the changes are marked with 'JCF'):
10164 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10166 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10167 overlaying area for it (uses RegBankUsed[4]).
10169 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10170 bank zero as used by default. By default aslink locates the stack
10171 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10172 the creation of the .mem file. Delegates the allocation of data area
10173 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10174 the begining of the stack area to aslink.
10176 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10177 glue() in SDCCglue.c creates an area for it.
10179 2002-09-03 Borut Razem <borut.razem AT siol.net>
10180 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10181 sdcc/src/pic/glue.c:
10182 introduced atexit() handler for teporay files removal in case of
10183 errors, assertions, ...
10185 2002-08-29 Borut Razem <borut.razem AT siol.net>
10186 * sdcc/support/cpp2/auto-host_vc_in.h:
10187 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10188 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10189 Maybe there is a similar problem with BORLANDC? It should be checked!
10191 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10192 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10193 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10194 was not executed, and the compiler (cl) launched a warning:
10195 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10197 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10198 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10200 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10201 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10203 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10204 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10205 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10206 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10207 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10208 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10209 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10210 - added Release configuration in VS projects
10211 - review of compiler an linker options
10212 - VC .exe files are generated in bin_vc directory, not to interfere
10213 with binaries generated from other projects (cygwin, mingw, bcc ...)
10215 * sdcc/src/yacc.dsp: added
10217 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10218 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10219 and insert the version number definitions from .version
10221 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10223 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10224 added - genarate auto-host.h using auto-host_vc_in.h as template
10227 removed from CVS, generated automatically
10229 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10230 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10232 2002-08-11 Borut Razem <borut.razem AT siol.net>
10233 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10235 2002-08-10 Borut Razem <borut.razem AT siol.net>
10236 * src/SDCCmain.c (main):
10237 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10238 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10239 The consequence was that some temporary files were not removed.
10242 unification of code in functions tempfilename() and tempfile():
10243 function tempnam() is defined in Visual Studio 6.0 and .NET
10245 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10247 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10248 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10249 - removed compiler command line option /WX: Treats all warnings as errors
10250 - update a list of source files, included into the project
10252 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10253 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10254 changed project type to Generic Project so that can be correcly converted to VS.NET project
10256 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10258 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10260 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10262 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10263 added return 0 statements after assert() to make compiler happy
10265 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10266 added newline in the def file to keep MSC compiler satisfied
10268 * sdcc/src/z80/gen.c:
10269 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10270 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10271 - solved MSC error in function aopDump()
10273 * sdcc_vc.h: define PREFIX as "\\sdcc"
10275 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10276 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10279 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10280 - Rewrote the register banking algorithm.
10281 - Added pCode live-range analysis to registers (for now, only non-used and
10282 singly-used registers optimized away)
10284 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10286 * 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.

10315 2002-03-28 Johan Knol <johan AT balder>
10317 * src/SDCCval.c: fixed bug #532436
10319 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10321 Added "char *Processor" field to the port structure.
10324 Added -p option. Allows port dependent processor to be specified.
10327 Initialized the new field char *Processor field to NULL in all ports
10330 Compiler generated registers for interrupt context saving
10331 were not getting allocated.
10333 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10336 Fixed left shift. Will promote the left side of a left shift
10337 if a) left shifting more than size of operand or b) when assigned
10338 to something size > size of left side
10340 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10342 tons of changes. Register allocation has been
10343 rewritten. Added customization for the various PICs. Flow
10344 analysis is restructured. ...
10346 * src/pic/device.h:
10349 * src/pic/device.c:
10350 Added. device.c is a PIC port hack to accomodate variations

10355 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10357 2002-03-04 johanknol <johanknol AT manik>
10359 * /src/SDCCval.c: fixed
10361 const unsigned char arr[][2] = { { 0, 1 } };

10450 * sdcc/src/SDCCloop.c:
10451 Previous fix was not good. basic blocks that have "break" or "return" are
10452 not really partof a loop , but live ranges used in these blocks should
10453 be live thru the entire loop, so set partOfLoop but don't add them to
