213 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
215 Enabled VPATH feature: changed nearly all Makefiles (149 files).
216 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
218 One basic decision: e.g. src/clean.mk includes further files. In order
219 to make this work there are two solutions:
220 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
221 run configure on them. This way they can use
222 'include $(srcdir)/port-clean.mk'
223 - always include clean.mk by the Makefile at the same level. To avoid
224 that `make clean` tries to include and build Makefile.dep the
225 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
226 implemented, because now even `make uninstall` doesn't create
227 Makefile.in. clean.mk could be eliminated by pasting it in
230 * debugger/mcs51/Makefile.in: build own objects from library sources
231 (SLIB, SDCC) in current directory
233 * configure, configure.in: renamed --disable-device-lib-build in
234 --disable-device-lib; added --enable-doc, the required tools are
235 searched by configure; added result message; the toolchain for the
236 belonging ports are now only built, if the port is enabled.
238 * support/regression/*: all output is written in directory gen, because
239 the fwk and ports directories don't livet in the build tree using vpath
241 * doc/sdccman.lyx: renamed --disable-device-lib-build to
242 --disable-device-lib, added --enable-doc, added section VPATH
244 * sim/ucsim/configure.in,
245 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
246 z80 are enabled by default
248 2006-04-24 Raphael Neider <rneider AT web.de>
250 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
251 to config word, "pic14_"-prefixed some extern functions
252 (pic14_emitConfigWord): emit __config directive(s) if assignment to
253 config word has been found
254 * src/pic/device.h: added prototypes
255 * src/pic/pcode.c: added "pic14_"-prefix where needed

258 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

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

530 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
531 archive with gcc 4.1 on mips and wrote the patch"
533 2006-03-16 Raphael Neider <rneider AT web.de>
535 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
536 the left operand is shorter than the result (c* = lit-c* + int),
538 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
541 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
543 * src/.version: increased version number to 2.5.5
544 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
545 linking is done manually in pic16 port's _linkEdit,
546 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
547 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
548 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
549 allocate asmop as AOP_ACC,
550 (aopForRemat): added parameter 'bool result' in function declaration,
551 (pic16_aopGet): return AOP_ACC when accessing WREG,

563 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
564 call to allocReg, not by manually allocating a new one,
565 (pic16_assignRegisters): now before going through the register
566 allocating functions mark all registers as free. This eliminates some
567 side effects resulting from peephole parser done earlier in the backbone
569 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
571 * src/SDCCicode.c (geniCodeLogic),

627 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
628 which dumps before the function entry point a data byte which represents
629 the number of the local variables used by the specified function, added
630 'xinst' for initial support for Extended Instruction Support,
631 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
632 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
633 port->fun_prefix anymore (may change later),
634 (genFunction, genEndFunction): do not store/restore local registers for
635 _main (this should take care the --main-return command line option in
637 (genOr): removed some legacy pic-port instructions,
638 * src/pic16/genarith.c (genAddLit): re-enabled old code because
639 performing operations with SFR's causes data to be written more than
640 once to each SFR. Perhaps SFRs should be handled in special cases...
641 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
643 * src/pic16/main.c (_process_pragma): stack bound checking did not take
644 into account for stack starting position,
645 (struct OPTIONS pic16_optionsTable): added command line argument
646 --extended or -y for Extended Instruction Support,
647 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
648 (deassignLRs): *** perhaps the most important change, old 'for' code
649 (commented out for reference), didn't account for some registers which
650 were left marked 'not free' after a pointer operation. The change
651 reduces register usage a lot in some cases

3042 * (pic16_popGetTempRegCond): changed function prototype, now
3043 function takes also a bitVector argument v which holds the current
3044 set of registers that are allocated for stack access by aopForSym,
3045 registers allocated in aopForSym for accessing stack symbols are not
3046 any more part of the functions usedRegs field,
3047 * (genCall): some times aopOp is called for a stack variable to be
3048 send, aopForSym might perform the push, if this is true make sure
3049 that genCall doesn't push the variable twice by testing _G.resDirect,
3050 * (genFunction): changed testing for unspecified interrupt number
3051 from 256 to INTNO_UNSPEC,
3052 * modified selection scheme of frame pointer generation. Previously
3053 if function did use local registers a frame pointer was generated,
3054 now a frame pointer is generated only if function has arguments
3055 (that need PLUSW2 register access), or has stack arguments, or the
3056 compiler is not instructed to omit the frame pointer,
3057 * (genEndFunction): before restoring local registers that were saved
3058 in the function preamble, also restore the registers that *might*
3059 have been allocated for stack access,
3060 * (genRet): removed some old comments,
3061 * (genCmp, the active (RN's) version): added a call to the
3062 pic16_genCmp_special function to perform the compare with a more
3063 robust and optimized way,
3064 * (genInline): a feature has been added in inline code generation,
3065 which allows a wildcard variable substitution when writing inline
3066 assembly. Code is incomplete and experimental therefore undocumented,
3067 * (genCast): changed order of aopOp for result and right to allow
3068 aopForSym to directly load the result if possible,
3069 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3070 perform an optimized compare on some selected special occasions,
3071 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3072 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3073 generate an IVT any more,
3074 * src/pic16/main.c (pic16_optionsTable): added command line option
3076 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3077 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3079 * src/pic16/NOTES: Raphael Neider added in list of active developers
3080 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3081 jumptable_end to prevent bug #,
3082 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3083 inCond and outCond fields,
3084 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3085 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3086 turn off register spilling,
3087 * (packRegsForOneUse): synced with other ports' versions although it
3088 is not used currently,
3089 * (pic16_packRegisters): added an optimization while reading
3090 structure bitfields, some registers may be saved (malloc code is
3091 decreased by 80 bytes)
3093 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3095 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3096 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3097 this can be optimized more?
3099 2005-03-10 Raphael Neider <rneider AT web.de>
3101 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3102 genNearPointerGet): (hopefully) fixed access to bitfields via
3103 pointers (p->bitN = x; and x = p->bitN; failed)

3428 pic16_framepnt_*, pic16_stack_*, pic1_frame_* pointer variables to
3429 access stack and frame pointers. They are initially assigned to
3430 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
3431 accessing SFRs. Updated all occurences of modification of stack or
3432 frame pointer in gen.c and pcode.c,
3433 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
3434 assigning of a literal value to pointers,

3462 to hold the condition bit)
3463 * added new version of genCmp (old code available via #define)
3464 * added new version of genShiftLeft/genShiftRight in a generic
3465 way, now supports shifting by negative values

3477 from Raphael Neider,
3478 * src/pic16/pcode.c (pic16_newpCodeOpLit): removed casting to char
3479 for 8-bit literals. This fixes some literal operands which are sign
3480 extended to 16-bits ints when instruction needs only 8-bits.

3737 Adding support for replacing ljmps with sjmps in jumptables
3738 generated for switch statements. For now you need to set the
3739 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3740 Now 4 algorithms for mcs51 jumptable generation are used:
3741 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3742 addresses loaded pc-relative for up to 112 cases and stack-pushing
3743 target addresses loaded with offset from dptr for up to 256 cases.

3775 * added libc directory. The current version of LibC contains string
3776 functions, ctype functions and macros and some functions of the
3777 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3778 be extensively tested in the future. Standard disclaimer here.

3791 * (pic16_storeForReturn): optimized return of 0,
3792 * (genCmp): experimental code for new genCmp which uses PIC18's
3793 special compare&skip instructions. Initial tests fail some times
3794 with variables grater than 1 byte in size, so new code is disabled,
3795 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3797 * (genCast): began a fix to optimize the casting of a bit to another
3798 bit, now assigning a bitfield to another bitfield will fail, sorry,

3807 and 1 for banking instruction,
3808 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3809 caused stop processing pCodes after a inline assembly block,
3810 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3812 registers when it shouldn't,
3813 * src/pic16/ralloc.c (allocReg): add preliminary support for
3814 supporting a limited set of temporary registers,
3816 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3822 (genFunction): optimize RECEIVE iCodes in reentrant functions
3824 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6821 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6823 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6824 loaded with the linker search paths (-L arguments) and the libraries
6825 to be linked with the current source (-l arguments). Changes
6826 currently will affect only the pic16 port.
6827 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6828 include path the port specific paths and port specific libraries,
6829 * gplink command now contains the $3 argument,
6830 * src/pic16/device.h,
6831 * src/pic16/device.c,: structure PIC_device is made public and
6832 renamed to PIC16_device, the same for variable Pics which is renamed

6847 Documenting changes from previous commits.
6848 * configure.in (version 1.56),
6849 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6850 when generating output files to configure the pic16 library,
6851 but now I've commented it out, since gputils aren't installed in the
6852 SF compile farm, so library won't compile
6854 * device/lib/Makefile.in (version 1.56): initially I've added in
6855 target 'all' the prerequestive 'model-pic16' so it compiled the
6856 pic16 library, but now I've commented it out for the same reasons
6858 * added targets 'model-pic16' and 'objects-pic16' to compile the
6860 * added target 'port-specific-objects-pic16' to handle the
6861 generated libraries and copy them into the build/ directory
6862 * added target 'clean-intermediate-pic16' to clean intermediate
6863 files into pic16 directory
6864 * in target 'installdirs' added line to create directory pic16 in

6885 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6886 option so that it actually works. Made it specific to the z80, since
6887 the gbz80 doesn't have these kinds of I/O ports.
6889 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6891 * device/include/z180.h,

6915 via literal number. The symbol is placed in the corresponding
6916 position of the data ram
6917 * (pic16_dump_section): relocatable and absolute uninitialized
6918 data are now emitted in sorted order to reduce section naming,
6919 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6920 weren't marked as being in the access bank,
6922 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6924 Added portion of GNU PIC Library under the directory
6925 device/include/pic16 and device/lib/pic16. These files
6926 contain the declarations of SFRs for the PIC18Fxx2 devices.
6927 The directory is initialized via configure from toplevel.

7113 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7115 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7116 (default behaviour).
7118 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7120 A python script to validate compiler diagnostic messages. It can be
7121 used to verify that sdcc complains about bad c source code and
7122 gives a good location of the error.
7123 * support/valdiag/Makefile,
7124 * support/valdiag/valdiag.py,
7125 * support/valdiag/tests/*

7144 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7146 * sdcc.spec: updated
7147 * device/include/Makefile.in: don't install CVS directories

7149 * doc/Makefile: fixed install, added local_icons
7150 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7151 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7152 * src/ds390/gen.c (genRightShift): fixed bug #870788

7155 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7157 PIC16 port related changes:
7158 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7159 added variable stackPos,
7161 * gen.c: genCall, assignResultValue: added support for
7162 pushing/retrieving function parameters to/from stack,
7163 genFunction,genEndFunction: setup stack frame for the
7165 genAddrOf: will be changed according to bug 863624
7167 * added files genutils.c and genutils.h which contain gen*
7168 debugged and optimised functions extracted from gen.c
7170 * glue.c: added variable 'externs' which holds extern symbols,
7171 pic16emitRegularMap: is modified to properly handle relocatable
7172 symbols under the new scheme,
7173 pic16createInterruptVect: is modified
7174 pic16printPublics: is modified to emit 'global' assembler directives,
7175 added pic16_printExterns to print extern symbols,
7176 pic16glue: initializes stack/frame pointer in the beginning of
7177 the assembly output. Temporary hack, will be corrected later,
7178 because gplink yet does not support stack and SDCC does not
7179 yet support a type of crt0.o object to create the final binary.
7181 * Removed many lines that contain 8051 legacy code.
7182 * The code is finally placed under a 'code' directive.
7183 * Added port specific options.
7185 * _process_pragma: simplified since now we do not need *special*
7186 include file to define SFR registers. But a separate header
7187 will be needed. This will be developed later.
7188 * _pic16_parseOptions: added, parses port specific options:
7189 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7190 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7191 --preplace-udata-with=
7193 * _pic16_setDefaultOptions: modified to initialize section names,
7194 but hack is temporarly out of order since it needs improvement.
7195 * _pic16_genAssemblerPreamble: configuration words are emitted by
7196 their address instead of their name. This part is incomplete and
7197 supports only the 18Fxx2 devices. Other devices will emit an error
7198 during assembly since they do not contain the same set of config
7200 * _pic16_genIVT: is modified,
7202 * pcode.c: added definitions for some hardware registers that are needed
7204 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7205 All PCI entries are updated. Now LFSR is supported.
7206 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7207 * added pic16_newpCodeOpLit2 to support instructions with
7208 two literal arguments
7209 * pic16_pCode2str: corrected code that emits assembler instructions
7210 with two literal operands and those that have an access bit modifier
7211 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7212 this fixes a bug which caused some labels to be lost, when an
7213 assembler directive was added, i.e. banksel,
7214 * pic16_FixRegisterBanking: improved logic that causes the insertion
7216 * InlineFunction: functions that are called once, are not any more
7217 inlined. This can be a port option in the future,
7219 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7221 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7222 hold the corresponding uninitialized symbols,
7223 * pic16_allocProcessorRegister: registers have explicit marked the
7225 * pic16_allocInternalRegister: registers are explicit marked as
7227 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7228 processing list, so bit registers were lost,
7231 * ralloc.h: added field 'accessBank' and original symbol operand
7232 in register definition,
7233 * removed the field isMapped from register definition,
7235 ** Several functions have been removed from various sources:
7236 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7237 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7238 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7239 pic16_assignRelocatableRegisters
7241 ** others have been introduced:
7242 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7243 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7245 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7247 * support/scripts/inc2h.pl: changed definition of BIT_AT
7248 to emit 'sbit at' instead of 'bit at'. This was a request.
7250 PIC16 port related preliminary changes:
7251 * gen.c: prefixed function popRegFromString with
7252 pic16_ and all references to it corrected
7253 * pcode.c: all pic16_pc_* hardware registers prefixed
7254 with underscore (_),
7255 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7256 * ralloc.c: newReg(): when register is REG_SFR then
7257 set address to rIdx,
7258 pic16_allocProcessorRegister(): marks register wasUsed=0
7259 pic16_writeUsedRegs(): added a call to assign processor
7260 registers via pic16_assignFixedRegisters
7262 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7264 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7265 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7266 variables in unused register banks. Also the SSEG is placed
7267 wherever there is enough space for it, and IDATA can be anywhere
7268 in internal RAM. For now compile using -Wl-Y[stack_size].
7269 The mem file is different for this option as well, since it
7270 makes no sense of talking about DSEG lenght.
7272 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7274 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7275 in certain cases, e.g. when ROM assignment, patch provided
7276 from Albert den Haan.

8281 fetching of the pointer
8282 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8283 copied from genNearPointerSet()
8284 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8285 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8286 If they pop r0/r1 they must be called in the opposite order than aopOp().
8287 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8288 (resp. --stack-auto), prepared for --xstack

8299 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8301 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8302 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8303 type for bits was changed. It resulted in bit variables becoming
8304 global, which is not permitted in PIC 14 assembly output.
8306 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8308 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8321 A few small changes that speed up the peephole optimizer.
8325 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8327 Try to make the peephole optimizer smarter by maintaining
8328 an association between the assembly source code and the
8329 iCodes that originated them. Put this information to use
8330 with a new peephole rule condition "notVolatile" so that
8331 the rules can be aggressive yet still safe.
8336 * src/mcs51/peeph.def
8338 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8342 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8343 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8344 if the left or right operand symbols have the accuse flag set.
8346 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8348 Changed the type of the result of the ! (NOT) operator to char;
8349 previously it returned the same type as the source. This allows
8350 us to eliminate all the genFloatNot functions (all of its target
8351 implementations were very buggy) since !float can use the same
8354 * src/SDCCicode.c (ast2iCode): ! returns char
8355 * src/mcs51/gen.c (genNot, genNotFloat),
8356 * src/ds390/gen.c (genNot, genNotFloat),
8357 * src/z80/gen.c (genNot, genNotFloat),
8358 * src/pic/gen.c (genNot, genNotFloat),
8359 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
8361 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8363 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8364 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8365 during interrupts. Ensure WSAVE is located at a shared bank address.
8366 2. Fixed page selection in some places
8367 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8368 the registers name strings.
8369 4. Fixed "signed / unsigned compare" compiler warnings.
8370 5. The PIC port manages its own allocation of the general purpose
8371 registers, but makes no attempt to reuse them. As a result when
8372 compiling it soon runs out of general purpose registers. Some
8373 additional code was added to the files pcode.c and device.c to walk
8374 through the function call tree and rename the registers so that they
8384 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8385 genPlus() & genMinus() when the result is the same as left or right
8387 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8391 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8393 Made bitfield a distinct type from bit so that bitfields
8394 convert as per ANSI C and bits retain their traditional
8395 boolean style behaviour. Implemented bitfield support in
8403 * src/ds390/gen.c: bit v bitfield split
8404 * src/z80/gen.c: New support for bitfields
8405 * support/regression/tests/bitfields.c: reenabled z80,
8408 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8410 Rules 246.x, 247.x relate to bitfields, the others speed up
8411 access to xdata mapped I/O devices.
8413 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8415 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8417 Cleaned up genPackBits and genUnpackBits and added two helper
8418 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8419 for literal assignments in genPackBits (thanks to Frieder for
8425 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8427 Fixed bug #748310 (pointer to function type mishandled when the
8428 function name is omitted). Also fixed a SIGSEGV when a function
8429 attribute (reentrant, etc) is used on a non-function or on a
8430 function but misplaced before the parameter list.
8432 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8434 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8435 * support/Util/SDCCerr.h,
8436 * support/Util/SDCCerr.c: Added func attr misuse error msg
8438 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8440 Fixed bug #787649 by anonymous
8441 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

8457 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8459 Made the constant following the "interrupt" keyword optional. If
8460 omitted, the function will not automatically be given an entry
8461 in the interrupt vector table (similar to #pragma NOIV, but
8462 less syntacticly kludgy). The interrupt number is also now
8463 range checked. Also fixed a bug in the high order bit example

8477 * src/SDCCicode.c (operandOperation): rewritten some ops
8478 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8479 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8481 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8482 be re-activated by defining REDUCE_LITERALS)
8483 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8484 unsigned, but are signed by default
8485 * src/SDCCval.c (constVal): rearranged
8486 * src/SDCCval.c (valMod): preliminary fix
8487 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8993 added if/endif conditional macros to remove options help
8994 messages from optionsTable when a port is not configured, added
8995 support for the PIc16 port in the ports table, when executing
8996 the compiler with no port specified on command line, a default
8997 port is selected with the new macro DEFAULT_PORT which is
8998 defined in port.h, in setDefaultOptions() linkOptions is removed
8999 from initialization assignment, since now it is a set,
9000 parseCmdLine uses setParseWithComma for linkOptions, in
9001 linkEdit() linkOptions are accessed with new function indexSet()
9002 which returns the i'th item of a set variable. See SDCCset.c, in
9003 linkEdit() when calling buildCmdLine(), added linkOptions as
9004 last argument. Now users can pass arguments to gplink via the
9005 -Wl option, main() uses pic16glue() to glue up pic16 programs

9019 gpasm complaining and test the linkage with gplink, _linkCmd and
9020 _asmCmd changed to be more gplink and gpasm friendly
9021 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9022 produced an error when parsed, peep rule 12 is added to utilize
9023 movff, but it is commented out since the pCode does not support
9024 yet a command with 2 address arguments
9026 2003-05-18 <johan AT balder>
9028 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9051 2003-05-12 Borut Razem <borut.razem AT siol.net>
9053 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9055 2003-05-11 Borut Razem <borut.razem AT siol.net>
9057 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9058 the path of bin directory, so that PATH is the only env. variable, which has to be set
9059 in case of standard installation.

10087 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10089 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10091 * in \sdcc\as\mcs51\ changed these files in order to create an
10092 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10093 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10094 following files to include the previous two files: aslink.dsp,
10095 Makefile.aslink, Makefile.bcc, and Makefile.in.
10097 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10098 .adb instead of .cdb
10100 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10102 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10103 value from option --iram-size.
10105 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10107 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10110 2002-09-18 <wiml AT hhhh.org>
10112 * SDCClrange.h: exposed setFromRange() and setToRange()
10113 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10114 packRegsForAccUse() (bug 542397)
10115 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10116 multiple times and emitting the fetch operations more than once
10117 added aopGetUsesAcc() function to allow binary operators to
10118 fetch their operands in the correct order; made genMinus() emit
10119 compact code for X = LITERAL - Y
10121 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10122 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10123 sprintf() in line 1267.
10125 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10126 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10129 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10130 Changes to aslink (All the changes are marked with 'JCF'):
10132 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10135 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10136 area BSEG. Also moves, if possible, the DATA area down into the internal
10137 ram so more space is available.
10139 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10142 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10143 not bytes. Function summary() which creates a memory usage summary
10144 file with extension .mem. Reports of overlaping stack and small stack
10145 size. If the space for the stack is less than 16 bytes aslink trows a
10148 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10149 the 8051. Option 'y' for memory summary output file.
10151 Changes to sdcc (All the changes are marked with 'JCF'):
10153 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10155 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10156 overlaying area for it (uses RegBankUsed[4]).
10158 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10159 bank zero as used by default. By default aslink locates the stack
10160 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10161 the creation of the .mem file. Delegates the allocation of data area
10162 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10163 the begining of the stack area to aslink.
10165 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10166 glue() in SDCCglue.c creates an area for it.
10168 2002-09-03 Borut Razem <borut.razem AT siol.net>
10169 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10170 sdcc/src/pic/glue.c:
10171 introduced atexit() handler for teporay files removal in case of
10172 errors, assertions, ...
10174 2002-08-29 Borut Razem <borut.razem AT siol.net>
10175 * sdcc/support/cpp2/auto-host_vc_in.h:
10176 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10177 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10178 Maybe there is a similar problem with BORLANDC? It should be checked!
10180 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10181 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10182 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10183 was not executed, and the compiler (cl) launched a warning:
10184 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10186 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10187 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10189 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10190 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10192 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10193 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10194 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10195 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10196 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10197 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10198 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10199 - added Release configuration in VS projects
10200 - review of compiler an linker options
10201 - VC .exe files are generated in bin_vc directory, not to interfere
10202 with binaries generated from other projects (cygwin, mingw, bcc ...)
10204 * sdcc/src/yacc.dsp: added
10206 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10207 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10208 and insert the version number definitions from .version
10210 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10212 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10213 added - genarate auto-host.h using auto-host_vc_in.h as template
10216 removed from CVS, generated automatically
10218 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10219 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10221 2002-08-11 Borut Razem <borut.razem AT siol.net>
10222 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10224 2002-08-10 Borut Razem <borut.razem AT siol.net>
10225 * src/SDCCmain.c (main):
10226 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10227 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10228 The consequence was that some temporary files were not removed.
10231 unification of code in functions tempfilename() and tempfile():
10232 function tempnam() is defined in Visual Studio 6.0 and .NET
10234 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10236 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10237 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10238 - removed compiler command line option /WX: Treats all warnings as errors
10239 - update a list of source files, included into the project
10241 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10242 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10243 changed project type to Generic Project so that can be correcly converted to VS.NET project
10245 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10247 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10249 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10251 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10252 added return 0 statements after assert() to make compiler happy
10254 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10255 added newline in the def file to keep MSC compiler satisfied
10257 * sdcc/src/z80/gen.c:
10258 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10259 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10260 - solved MSC error in function aopDump()
10262 * sdcc_vc.h: define PREFIX as "\\sdcc"
10264 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10265 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10268 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10269 - Rewrote the register banking algorithm.
10270 - Added pCode live-range analysis to registers (for now, only non-used and
10271 singly-used registers optimized away)
10273 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10275 * 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.

10302 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10304 2002-03-28 Johan Knol <johan AT balder>
10306 * src/SDCCval.c: fixed bug #532436
10308 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10310 Added "char *Processor" field to the port structure.
10313 Added -p option. Allows port dependent processor to be specified.
10316 Initialized the new field char *Processor field to NULL in all ports
10319 Compiler generated registers for interrupt context saving
10320 were not getting allocated.
10322 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10325 Fixed left shift. Will promote the left side of a left shift
10326 if a) left shifting more than size of operand or b) when assigned
10327 to something size > size of left side
10329 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10331 tons of changes. Register allocation has been
10332 rewritten. Added customization for the various PICs. Flow
10333 analysis is restructured. ...
10335 * src/pic/device.h:
10338 * src/pic/device.c:
10339 Added. device.c is a PIC port hack to accomodate variations
10342 2002-03-13 Michael Hope <michaelh AT vroom>
10344 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10346 2002-03-04 johanknol <johanknol AT manik>
10348 * /src/SDCCval.c: fixed
10350 const unsigned char arr[][2] = { { 0, 1 } };

10439 * sdcc/src/SDCCloop.c:
10440 Previous fix was not good. basic blocks that have "break" or "return" are
10441 not really partof a loop , but live ranges used in these blocks should
10442 be live thru the entire loop, so set partOfLoop but don't add them to
