427 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
428 moved to level 0 and declared as static. Also they are explicit

444 * (pic16_popGetTempRegCond): changed function prototype, now
445 function takes also a bitVector argument v which holds the current
446 set of registers that are allocated for stack access by aopForSym,
447 registers allocated in aopForSym for accessing stack symbols are not
448 any more part of the functions usedRegs field,
449 * (genCall): some times aopOp is called for a stack variable to be
450 send, aopForSym might perform the push, if this is true make sure
451 that genCall doesn't push the variable twice by testing _G.resDirect,
452 * (genFunction): changed testing for unspecified interrupt number
453 from 256 to INTNO_UNSPEC,
454 * modified selection scheme of frame pointer generation. Previously
455 if function did use local registers a frame pointer was generated,
456 now a frame pointer is generated only if function has arguments
457 (that need PLUSW2 register access), or has stack arguments, or the
458 compiler is not instructed to omit the frame pointer,
459 * (genEndFunction): before restoring local registers that were saved
460 in the function preamble, also restore the registers that *might*
461 have been allocated for stack access,
462 * (genRet): removed some old comments,
463 * (genCmp, the active (RN's) version): added a call to the
464 pic16_genCmp_special function to perform the compare with a more
465 robust and optimized way,
466 * (genInline): a feature has been added in inline code generation,
467 which allows a wildcard variable substitution when writing inline
468 assembly. Code is incomplete and experimental therefore undocumented,
469 * (genCast): changed order of aopOp for result and right to allow
470 aopForSym to directly load the result if possible,
471 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
472 perform an optimized compare on some selected special occasions,
473 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
474 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
475 generate an IVT any more,
476 * src/pic16/main.c (pic16_optionsTable): added command line option
478 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
479 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
481 * src/pic16/NOTES: Raphael Neider added in list of active developers
482 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
483 jumptable_end to prevent bug #,
484 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
485 inCond and outCond fields,
486 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
487 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
488 turn off register spilling,
489 * (packRegsForOneUse): synced with other ports' versions although it
490 is not used currently,
491 * (pic16_packRegisters): added an optimization while reading
492 structure bitfields, some registers may be saved (malloc code is
493 decreased by 80 bytes)
495 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
497 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
498 left is a bitfield, if yes, then don't optimize assignment. Perhaps
499 this can be optimized more?
501 2005-03-10 Raphael Neider <rneider AT web.de>
503 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
504 genNearPointerGet): (hopefully) fixed access to bitfields via
505 pointers (p->bitN = x; and x = p->bitN; failed)

1140 generated for switch statements. For now you need to set the
1141 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1142 Now 4 algorithms for mcs51 jumptable generation are used:
1143 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1177 * added libc directory. The current version of LibC contains string
1178 functions, ctype functions and macros and some functions of the
1179 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1180 be extensively tested in the future. Standard disclaimer here.
1181 Library is not automatically build yet. But one can build it by

1193 * (pic16_storeForReturn): optimized return of 0,
1194 * (genCmp): experimental code for new genCmp which uses PIC18's
1195 special compare&skip instructions. Initial tests fail some times
1196 with variables grater than 1 byte in size, so new code is disabled,
1197 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1199 * (genCast): began a fix to optimize the casting of a bit to another
1200 bit, now assigning a bitfield to another bitfield will fail, sorry,

1209 and 1 for banking instruction,
1210 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1211 caused stop processing pCodes after a inline assembly block,
1212 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1214 registers when it shouldn't,
1215 * src/pic16/ralloc.c (allocReg): add preliminary support for
1216 supporting a limited set of temporary registers,
1218 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4226 loaded with the linker search paths (-L arguments) and the libraries
4227 to be linked with the current source (-l arguments). Changes
4228 currently will affect only the pic16 port.
4229 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4230 include path the port specific paths and port specific libraries,
4231 * gplink command now contains the $3 argument,
4232 * src/pic16/device.h,

4249 Documenting changes from previous commits.
4250 * configure.in (version 1.56),
4251 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4252 when generating output files to configure the pic16 library,
4253 but now I've commented it out, since gputils aren't installed in the
4254 SF compile farm, so library won't compile
4256 * device/lib/Makefile.in (version 1.56): initially I've added in
4257 target 'all' the prerequestive 'model-pic16' so it compiled the
4258 pic16 library, but now I've commented it out for the same reasons
4260 * added targets 'model-pic16' and 'objects-pic16' to compile the
4262 * added target 'port-specific-objects-pic16' to handle the
4263 generated libraries and copy them into the build/ directory
4264 * added target 'clean-intermediate-pic16' to clean intermediate
4265 files into pic16 directory
4266 * in target 'installdirs' added line to create directory pic16 in

4512 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
4513 LEFT_OP (left shift)
4515 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4517 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4518 (default behaviour).
4520 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4522 A python script to validate compiler diagnostic messages. It can be
4523 used to verify that sdcc complains about bad c source code and
4524 gives a good location of the error.
4525 * support/valdiag/Makefile,
4526 * support/valdiag/valdiag.py,
4527 * support/valdiag/tests/*

4544 Bug reported from Jesus Calvino-Fraga
4546 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4548 * sdcc.spec: updated
4549 * device/include/Makefile.in: don't install CVS directories
4550 * device/lib/Makefile.in: added removal of CVS directories after install
4551 * doc/Makefile: fixed install, added local_icons
4552 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4553 * src/mcs51/gen.c (genRightShift): fixed bug #870788

4557 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4559 PIC16 port related changes:
4560 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4561 added variable stackPos,
4563 * gen.c: genCall, assignResultValue: added support for
4564 pushing/retrieving function parameters to/from stack,
4565 genFunction,genEndFunction: setup stack frame for the
4567 genAddrOf: will be changed according to bug 863624
4569 * added files genutils.c and genutils.h which contain gen*
4570 debugged and optimised functions extracted from gen.c
4572 * glue.c: added variable 'externs' which holds extern symbols,
4573 pic16emitRegularMap: is modified to properly handle relocatable
4574 symbols under the new scheme,
4575 pic16createInterruptVect: is modified
4576 pic16printPublics: is modified to emit 'global' assembler directives,
4577 added pic16_printExterns to print extern symbols,
4578 pic16glue: initializes stack/frame pointer in the beginning of
4579 the assembly output. Temporary hack, will be corrected later,
4580 because gplink yet does not support stack and SDCC does not
4581 yet support a type of crt0.o object to create the final binary.
4583 * Removed many lines that contain 8051 legacy code.
4584 * The code is finally placed under a 'code' directive.
4585 * Added port specific options.
4587 * _process_pragma: simplified since now we do not need *special*
4588 include file to define SFR registers. But a separate header
4589 will be needed. This will be developed later.
4590 * _pic16_parseOptions: added, parses port specific options:
4591 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4592 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4593 --preplace-udata-with=
4595 * _pic16_setDefaultOptions: modified to initialize section names,
4596 but hack is temporarly out of order since it needs improvement.
4597 * _pic16_genAssemblerPreamble: configuration words are emitted by
4598 their address instead of their name. This part is incomplete and
4599 supports only the 18Fxx2 devices. Other devices will emit an error
4600 during assembly since they do not contain the same set of config
4602 * _pic16_genIVT: is modified,
4604 * pcode.c: added definitions for some hardware registers that are needed
4606 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4607 All PCI entries are updated. Now LFSR is supported.
4608 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4609 * added pic16_newpCodeOpLit2 to support instructions with
4610 two literal arguments
4611 * pic16_pCode2str: corrected code that emits assembler instructions
4612 with two literal operands and those that have an access bit modifier
4613 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4614 this fixes a bug which caused some labels to be lost, when an
4615 assembler directive was added, i.e. banksel,
4616 * pic16_FixRegisterBanking: improved logic that causes the insertion
4618 * InlineFunction: functions that are called once, are not any more
4619 inlined. This can be a port option in the future,
4621 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4623 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4624 hold the corresponding uninitialized symbols,
4625 * pic16_allocProcessorRegister: registers have explicit marked the
4627 * pic16_allocInternalRegister: registers are explicit marked as
4629 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4630 processing list, so bit registers were lost,
4633 * ralloc.h: added field 'accessBank' and original symbol operand
4634 in register definition,
4635 * removed the field isMapped from register definition,
4637 ** Several functions have been removed from various sources:
4638 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4639 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4640 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4641 pic16_assignRelocatableRegisters
4643 ** others have been introduced:
4644 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4645 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4647 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4649 * support/scripts/inc2h.pl: changed definition of BIT_AT
4650 to emit 'sbit at' instead of 'bit at'. This was a request.
4652 PIC16 port related preliminary changes:
4653 * gen.c: prefixed function popRegFromString with
4654 pic16_ and all references to it corrected
4655 * pcode.c: all pic16_pc_* hardware registers prefixed
4656 with underscore (_),
4657 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4658 * ralloc.c: newReg(): when register is REG_SFR then
4659 set address to rIdx,
4660 pic16_allocProcessorRegister(): marks register wasUsed=0
4661 pic16_writeUsedRegs(): added a call to assign processor
4662 registers via pic16_assignFixedRegisters
4664 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4666 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4667 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4668 variables in unused register banks. Also the SSEG is placed
4669 wherever there is enough space for it, and IDATA can be anywhere
4670 in internal RAM. For now compile using -Wl-Y[stack_size].
4671 The mem file is different for this option as well, since it
4672 makes no sense of talking about DSEG lenght.
4674 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4676 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4677 in certain cases, e.g. when ROM assignment, patch provided
4678 from Albert den Haan.
4680 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4919 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4921 * src/SDCCast.c (decorateType): disabled a transformation I added in
4922 revision 1.188 (access to fields of a structure at an absolute address);
4923 it breaks with bitfields, extern declarations, and gcse analysis.
4924 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4925 could be assigned through a pointer, so don't complain.
4926 * src/SDCCast.c (astErrors),
4928 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
4930 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

4936 pre-processor macro, i.e. -DMCU=p18f452
4937 * src/pic16/ralloc.c: renamed packRegisters to pic16_packRegisters,
4938 and modified to handle 'cast' icode similarly to '=' icode

5681 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5682 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5683 fetching of the pointer
5684 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5685 copied from genNearPointerSet()
5686 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5687 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5688 If they pop r0/r1 they must be called in the opposite order than aopOp().
5689 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"

5703 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5704 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5705 type for bits was changed. It resulted in bit variables becoming
5706 global, which is not permitted in PIC 14 assembly output.
5708 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5723 A few small changes that speed up the peephole optimizer.
5727 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5729 Try to make the peephole optimizer smarter by maintaining
5730 an association between the assembly source code and the
5731 iCodes that originated them. Put this information to use
5732 with a new peephole rule condition "notVolatile" so that
5733 the rules can be aggressive yet still safe.
5738 * src/mcs51/peeph.def
5740 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5744 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5745 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5746 if the left or right operand symbols have the accuse flag set.
5748 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5750 Changed the type of the result of the ! (NOT) operator to char;
5751 previously it returned the same type as the source. This allows
5752 us to eliminate all the genFloatNot functions (all of its target
5753 implementations were very buggy) since !float can use the same

5766 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5767 during interrupts. Ensure WSAVE is located at a shared bank address.
5768 2. Fixed page selection in some places
5769 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5770 the registers name strings.
5771 4. Fixed "signed / unsigned compare" compiler warnings.
5772 5. The PIC port manages its own allocation of the general purpose
5773 registers, but makes no attempt to reuse them. As a result when
5774 compiling it soon runs out of general purpose registers. Some
5775 additional code was added to the files pcode.c and device.c to walk
5776 through the function call tree and rename the registers so that they
5786 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5793 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5795 Made bitfield a distinct type from bit so that bitfields
5796 convert as per ANSI C and bits retain their traditional
5797 boolean style behaviour. Implemented bitfield support in
5805 * src/ds390/gen.c: bit v bitfield split
5806 * src/z80/gen.c: New support for bitfields
5807 * support/regression/tests/bitfields.c: reenabled z80,
5810 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5812 Rules 246.x, 247.x relate to bitfields, the others speed up
5813 access to xdata mapped I/O devices.
5815 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5817 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5819 Cleaned up genPackBits and genUnpackBits and added two helper
5820 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5821 for literal assignments in genPackBits (thanks to Frieder for
5827 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5829 Fixed bug #748310 (pointer to function type mishandled when the
5830 function name is omitted). Also fixed a SIGSEGV when a function
5831 attribute (reentrant, etc) is used on a non-function or on a
5832 function but misplaced before the parameter list.
5834 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5836 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5859 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5861 Made the constant following the "interrupt" keyword optional. If
5862 omitted, the function will not automatically be given an entry
5863 in the interrupt vector table (similar to #pragma NOIV, but
5864 less syntacticly kludgy). The interrupt number is also now
5865 range checked. Also fixed a bug in the high order bit example

6395 added if/endif conditional macros to remove options help
6396 messages from optionsTable when a port is not configured, added
6397 support for the PIc16 port in the ports table, when executing
6398 the compiler with no port specified on command line, a default
6399 port is selected with the new macro DEFAULT_PORT which is
6400 defined in port.h, in setDefaultOptions() linkOptions is removed
6401 from initialization assignment, since now it is a set,
6402 parseCmdLine uses setParseWithComma for linkOptions, in
6403 linkEdit() linkOptions are accessed with new function indexSet()
6404 which returns the i'th item of a set variable. See SDCCset.c, in
6405 linkEdit() when calling buildCmdLine(), added linkOptions as
6406 last argument. Now users can pass arguments to gplink via the
6407 -Wl option, main() uses pic16glue() to glue up pic16 programs

6421 gpasm complaining and test the linkage with gplink, _linkCmd and
6422 _asmCmd changed to be more gplink and gpasm friendly
6423 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6424 produced an error when parsed, peep rule 12 is added to utilize
6425 movff, but it is commented out since the pCode does not support
6426 yet a command with 2 address arguments
6428 2003-05-18 <johan AT balder>
6430 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7463 2003-01-06 <johan AT balder>
7465 * src/SDCCicode.c: fixed array add
7467 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7468 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7469 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7471 2003-01-04 <johan AT balder>
7473 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7475 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7476 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7478 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7479 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

7488 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7489 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7491 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7493 * in \sdcc\as\mcs51\ changed these files in order to create an
7494 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7495 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7496 following files to include the previous two files: aslink.dsp,
7497 Makefile.aslink, Makefile.bcc, and Makefile.in.
7499 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7500 .adb instead of .cdb
7502 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7504 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7505 value from option --iram-size.
7507 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7509 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7512 2002-09-18 <wiml AT hhhh.org>
7514 * SDCClrange.h: exposed setFromRange() and setToRange()
7515 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7516 packRegsForAccUse() (bug 542397)
7517 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7518 multiple times and emitting the fetch operations more than once
7519 added aopGetUsesAcc() function to allow binary operators to
7520 fetch their operands in the correct order; made genMinus() emit
7521 compact code for X = LITERAL - Y
7523 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7524 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7525 sprintf() in line 1267.
7527 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7528 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7531 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7532 Changes to aslink (All the changes are marked with 'JCF'):
7534 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7537 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7538 area BSEG. Also moves, if possible, the DATA area down into the internal
7539 ram so more space is available.
7541 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7544 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7545 not bytes. Function summary() which creates a memory usage summary
7546 file with extension .mem. Reports of overlaping stack and small stack
7547 size. If the space for the stack is less than 16 bytes aslink trows a
7550 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7551 the 8051. Option 'y' for memory summary output file.
7553 Changes to sdcc (All the changes are marked with 'JCF'):
7555 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7557 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7558 overlaying area for it (uses RegBankUsed[4]).
7560 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7561 bank zero as used by default. By default aslink locates the stack
7562 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7563 the creation of the .mem file. Delegates the allocation of data area
7564 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7565 the begining of the stack area to aslink.
7567 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7568 glue() in SDCCglue.c creates an area for it.
7570 2002-09-03 Borut Razem <borut.razem AT siol.net>
7571 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7572 sdcc/src/pic/glue.c:
7573 introduced atexit() handler for teporay files removal in case of
7574 errors, assertions, ...
7576 2002-08-29 Borut Razem <borut.razem AT siol.net>
7577 * sdcc/support/cpp2/auto-host_vc_in.h:
7578 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7579 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7580 Maybe there is a similar problem with BORLANDC? It should be checked!
7582 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7583 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7584 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7585 was not executed, and the compiler (cl) launched a warning:
7586 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7588 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7589 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7591 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7592 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7594 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7595 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7596 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7597 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7598 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7599 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7600 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7601 - added Release configuration in VS projects
7602 - review of compiler an linker options
7603 - VC .exe files are generated in bin_vc directory, not to interfere
7604 with binaries generated from other projects (cygwin, mingw, bcc ...)
7606 * sdcc/src/yacc.dsp: added
7608 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7609 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7610 and insert the version number definitions from .version
7612 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7614 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7615 added - genarate auto-host.h using auto-host_vc_in.h as template
7618 removed from CVS, generated automatically
7620 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7621 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7623 2002-08-11 Borut Razem <borut.razem AT siol.net>
7624 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7626 2002-08-10 Borut Razem <borut.razem AT siol.net>
7627 * src/SDCCmain.c (main):
7628 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7629 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7630 The consequence was that some temporary files were not removed.
7633 unification of code in functions tempfilename() and tempfile():
7634 function tempnam() is defined in Visual Studio 6.0 and .NET
7636 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7638 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7639 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7640 - removed compiler command line option /WX: Treats all warnings as errors
7641 - update a list of source files, included into the project
7643 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7644 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7645 changed project type to Generic Project so that can be correcly converted to VS.NET project
7647 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7649 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7651 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7653 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7654 added return 0 statements after assert() to make compiler happy
7656 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7657 added newline in the def file to keep MSC compiler satisfied
7659 * sdcc/src/z80/gen.c:
7660 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7661 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7662 - solved MSC error in function aopDump()
7664 * sdcc_vc.h: define PREFIX as "\\sdcc"
7666 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7667 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7670 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7671 - Rewrote the register banking algorithm.
7672 - Added pCode live-range analysis to registers (for now, only non-used and
7673 singly-used registers optimized away)
7675 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7677 * 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.

7704 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7706 2002-03-28 Johan Knol <johan AT balder>
7708 * src/SDCCval.c: fixed bug #532436
7710 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7712 Added "char *Processor" field to the port structure.
7715 Added -p option. Allows port dependent processor to be specified.
7718 Initialized the new field char *Processor field to NULL in all ports
7721 Compiler generated registers for interrupt context saving
7722 were not getting allocated.
7724 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7727 Fixed left shift. Will promote the left side of a left shift
7728 if a) left shifting more than size of operand or b) when assigned
7729 to something size > size of left side
7731 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7733 tons of changes. Register allocation has been
7734 rewritten. Added customization for the various PICs. Flow
7735 analysis is restructured. ...
7741 Added. device.c is a PIC port hack to accomodate variations
7744 2002-03-13 Michael Hope <michaelh AT vroom>
7746 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7748 2002-03-04 johanknol <johanknol AT manik>
7750 * /src/SDCCval.c: fixed
7752 const unsigned char arr[][2] = { { 0, 1 } };
7753 t18.c:1: error: Initializer element is not constant
7755 2002-03-04 bela <bela AT manik>
7757 * /device/include/mcs51reg.h:
7758 ds89c420 register definition update
7760 2002-03-03 <johan AT FRIJA>

7839 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7841 * sdcc/src/SDCCloop.c:
7842 Previous fix was not good. basic blocks that have "break" or "return" are
7843 not really partof a loop , but live ranges used in these blocks should
7844 be live thru the entire loop, so set partOfLoop but don't add them to
7847 2002-02-21 <johan AT FRIJA>
7849 * src/SDCCcse.c: fixed bug #514308
7851 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7854 Fixed BUG #519583. If a conditional block ended in a return/break
7855 statement inside a loop, it was not being considered part of the loop.
7857 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7859 2002-02-10 Karl Bongers <karl AT turbobit.com>
7862 Fixed up SDCDB debugger somewhat. Updated debugger/README
7863 with lots of comments and notes.
7865 * device/examples/test2.c:
7866 Fix bug, "red" variable not being initialized(compiler complained).
7868 * device/examples/Makefile, examples/test3.c:
7869 Add Makefile in device/examples folder, compiles test3.c
7870 for use as a multiple module SDCDB test case.
7872 * sim/ucsim/cmd.src/cmdset.cc:
7873 Took out debug printfs in ucsim "next" command.
7876 Karl and Johan start ucsim XA support. Most dissassembly working,
7877 about 75% emulation done(plenty of work remaining).
7879 * sim/ucsim/z80.src:
7880 Add Z80 support to ucsim, add test-ucz80 regression test,
7881 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
7882 Notice z80 compiler fails on examples/test3.c/crc code.
7884 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
7886 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
7887 Added support for --parms-in-bank1
7889 * src/ds390/peeph.def:
7890 added a few more peephole optimzations
7893 1) added __builtin_inp & __builtin_outp used to read in data of given length
7894 from a memory mapped port
