455 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
457 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
458 prevent compiler warning
460 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
462 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
463 moved to level 0 and declared as static. Also they are explicit
464 placed in access bank. This was necessery because some times they
465 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
466 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
467 optimizations. Currently only compare to unsigned char is implemented,
468 * src/pic16/gen.c: added fReturnIdx array,
469 * (struct resolvedIfx) is moved to gen.h and made public,
470 * (struct _G): added sregsAlloc and sregsAllocSet fields,
471 * (aopForSym): added an optimization to directly store in stack of
472 the operand of a SEND iCode,
473 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
474 but as registers instead (AOP_REG) using the fReturnIdx array,
475 * (pic16_freeAsmop): remove the freed register from the
477 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
479 * (pic16_popGetTempRegCond): changed function prototype, now
480 function takes also a bitVector argument v which holds the current
481 set of registers that are allocated for stack access by aopForSym,
482 registers allocated in aopForSym for accessing stack symbols are not
483 any more part of the functions usedRegs field,
484 * (genCall): some times aopOp is called for a stack variable to be
485 send, aopForSym might perform the push, if this is true make sure
486 that genCall doesn't push the variable twice by testing _G.resDirect,
487 * (genFunction): changed testing for unspecified interrupt number
488 from 256 to INTNO_UNSPEC,
489 * modified selection scheme of frame pointer generation. Previously
490 if function did use local registers a frame pointer was generated,
491 now a frame pointer is generated only if function has arguments
492 (that need PLUSW2 register access), or has stack arguments, or the
493 compiler is not instructed to omit the frame pointer,
494 * (genEndFunction): before restoring local registers that were saved
495 in the function preamble, also restore the registers that *might*
496 have been allocated for stack access,
497 * (genRet): removed some old comments,
498 * (genCmp, the active (RN's) version): added a call to the
499 pic16_genCmp_special function to perform the compare with a more
500 robust and optimized way,
501 * (genInline): a feature has been added in inline code generation,
502 which allows a wildcard variable substitution when writing inline
503 assembly. Code is incomplete and experimental therefore undocumented,
504 * (genCast): changed order of aopOp for result and right to allow
505 aopForSym to directly load the result if possible,
506 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
507 perform an optimized compare on some selected special occasions,
508 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
509 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
510 generate an IVT any more,
511 * src/pic16/main.c (pic16_optionsTable): added command line option
513 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
514 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
516 * src/pic16/NOTES: Raphael Neider added in list of active developers
517 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
518 jumptable_end to prevent bug #,
519 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
520 inCond and outCond fields,
521 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
522 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
523 turn off register spilling,
524 * (packRegsForOneUse): synced with other ports' versions although it
525 is not used currently,
526 * (pic16_packRegisters): added an optimization while reading
527 structure bitfields, some registers may be saved (malloc code is
528 decreased by 80 bytes)
530 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
532 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
533 left is a bitfield, if yes, then don't optimize assignment. Perhaps
534 this can be optimized more?
536 2005-03-10 Raphael Neider <rneider AT web.de>
538 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
539 genNearPointerGet): (hopefully) fixed access to bitfields via
540 pointers (p->bitN = x; and x = p->bitN; failed)

1175 generated for switch statements. For now you need to set the
1176 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1177 Now 4 algorithms for mcs51 jumptable generation are used:
1178 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1210 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1212 * added libc directory. The current version of LibC contains string
1213 functions, ctype functions and macros and some functions of the
1214 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1215 be extensively tested in the future. Standard disclaimer here.

1228 * (pic16_storeForReturn): optimized return of 0,
1229 * (genCmp): experimental code for new genCmp which uses PIC18's
1230 special compare&skip instructions. Initial tests fail some times
1231 with variables grater than 1 byte in size, so new code is disabled,
1232 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1234 * (genCast): began a fix to optimize the casting of a bit to another
1235 bit, now assigning a bitfield to another bitfield will fail, sorry,

1244 and 1 for banking instruction,
1245 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1246 caused stop processing pCodes after a inline assembly block,
1247 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1249 registers when it shouldn't,
1250 * src/pic16/ralloc.c (allocReg): add preliminary support for
1251 supporting a limited set of temporary registers,
1253 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1259 (genFunction): optimize RECEIVE iCodes in reentrant functions
1261 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4260 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4261 loaded with the linker search paths (-L arguments) and the libraries
4262 to be linked with the current source (-l arguments). Changes
4263 currently will affect only the pic16 port.
4264 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4265 include path the port specific paths and port specific libraries,
4266 * gplink command now contains the $3 argument,
4267 * src/pic16/device.h,
4268 * src/pic16/device.c,: structure PIC_device is made public and
4269 renamed to PIC16_device, the same for variable Pics which is renamed

4284 Documenting changes from previous commits.
4285 * configure.in (version 1.56),
4286 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4287 when generating output files to configure the pic16 library,
4288 but now I've commented it out, since gputils aren't installed in the
4289 SF compile farm, so library won't compile
4291 * device/lib/Makefile.in (version 1.56): initially I've added in
4292 target 'all' the prerequestive 'model-pic16' so it compiled the
4293 pic16 library, but now I've commented it out for the same reasons
4295 * added targets 'model-pic16' and 'objects-pic16' to compile the
4297 * added target 'port-specific-objects-pic16' to handle the
4298 generated libraries and copy them into the build/ directory
4299 * added target 'clean-intermediate-pic16' to clean intermediate
4300 files into pic16 directory
4301 * in target 'installdirs' added line to create directory pic16 in

4322 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4323 option so that it actually works. Made it specific to the z80, since
4324 the gbz80 doesn't have these kinds of I/O ports.
4326 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4328 * device/include/z180.h,

4352 via literal number. The symbol is placed in the corresponding
4353 position of the data ram
4354 * (pic16_dump_section): relocatable and absolute uninitialized
4355 data are now emitted in sorted order to reduce section naming,
4356 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4357 weren't marked as being in the access bank,

4550 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4552 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4553 (default behaviour).
4555 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4557 A python script to validate compiler diagnostic messages. It can be
4558 used to verify that sdcc complains about bad c source code and
4559 gives a good location of the error.
4560 * support/valdiag/Makefile,
4561 * support/valdiag/valdiag.py,
4562 * support/valdiag/tests/*

4579 Bug reported from Jesus Calvino-Fraga
4581 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4583 * sdcc.spec: updated
4584 * device/include/Makefile.in: don't install CVS directories
4585 * device/lib/Makefile.in: added removal of CVS directories after install
4586 * doc/Makefile: fixed install, added local_icons
4587 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4588 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4589 * src/ds390/gen.c (genRightShift): fixed bug #870788

4592 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4594 PIC16 port related changes:
4595 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4596 added variable stackPos,
4598 * gen.c: genCall, assignResultValue: added support for
4599 pushing/retrieving function parameters to/from stack,
4600 genFunction,genEndFunction: setup stack frame for the
4602 genAddrOf: will be changed according to bug 863624
4604 * added files genutils.c and genutils.h which contain gen*
4605 debugged and optimised functions extracted from gen.c
4607 * glue.c: added variable 'externs' which holds extern symbols,
4608 pic16emitRegularMap: is modified to properly handle relocatable
4609 symbols under the new scheme,
4610 pic16createInterruptVect: is modified
4611 pic16printPublics: is modified to emit 'global' assembler directives,
4612 added pic16_printExterns to print extern symbols,
4613 pic16glue: initializes stack/frame pointer in the beginning of
4614 the assembly output. Temporary hack, will be corrected later,
4615 because gplink yet does not support stack and SDCC does not
4616 yet support a type of crt0.o object to create the final binary.
4618 * Removed many lines that contain 8051 legacy code.
4619 * The code is finally placed under a 'code' directive.
4620 * Added port specific options.
4622 * _process_pragma: simplified since now we do not need *special*
4623 include file to define SFR registers. But a separate header
4624 will be needed. This will be developed later.
4625 * _pic16_parseOptions: added, parses port specific options:
4626 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4627 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4628 --preplace-udata-with=
4630 * _pic16_setDefaultOptions: modified to initialize section names,
4631 but hack is temporarly out of order since it needs improvement.
4632 * _pic16_genAssemblerPreamble: configuration words are emitted by
4633 their address instead of their name. This part is incomplete and
4634 supports only the 18Fxx2 devices. Other devices will emit an error
4635 during assembly since they do not contain the same set of config
4637 * _pic16_genIVT: is modified,
4639 * pcode.c: added definitions for some hardware registers that are needed
4641 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4642 All PCI entries are updated. Now LFSR is supported.
4643 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4644 * added pic16_newpCodeOpLit2 to support instructions with
4645 two literal arguments
4646 * pic16_pCode2str: corrected code that emits assembler instructions
4647 with two literal operands and those that have an access bit modifier
4648 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4649 this fixes a bug which caused some labels to be lost, when an
4650 assembler directive was added, i.e. banksel,
4651 * pic16_FixRegisterBanking: improved logic that causes the insertion
4653 * InlineFunction: functions that are called once, are not any more
4654 inlined. This can be a port option in the future,
4656 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4658 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4659 hold the corresponding uninitialized symbols,
4660 * pic16_allocProcessorRegister: registers have explicit marked the
4662 * pic16_allocInternalRegister: registers are explicit marked as
4664 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4665 processing list, so bit registers were lost,
4668 * ralloc.h: added field 'accessBank' and original symbol operand
4669 in register definition,
4670 * removed the field isMapped from register definition,
4672 ** Several functions have been removed from various sources:
4673 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4674 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4675 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4676 pic16_assignRelocatableRegisters
4678 ** others have been introduced:
4679 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4680 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4682 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4684 * support/scripts/inc2h.pl: changed definition of BIT_AT
4685 to emit 'sbit at' instead of 'bit at'. This was a request.
4687 PIC16 port related preliminary changes:
4688 * gen.c: prefixed function popRegFromString with
4689 pic16_ and all references to it corrected
4690 * pcode.c: all pic16_pc_* hardware registers prefixed
4691 with underscore (_),
4692 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4693 * ralloc.c: newReg(): when register is REG_SFR then
4694 set address to rIdx,
4695 pic16_allocProcessorRegister(): marks register wasUsed=0
4696 pic16_writeUsedRegs(): added a call to assign processor
4697 registers via pic16_assignFixedRegisters
4699 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4701 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4702 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4703 variables in unused register banks. Also the SSEG is placed
4704 wherever there is enough space for it, and IDATA can be anywhere
4705 in internal RAM. For now compile using -Wl-Y[stack_size].
4706 The mem file is different for this option as well, since it
4707 makes no sense of talking about DSEG lenght.
4709 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4711 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4712 in certain cases, e.g. when ROM assignment, patch provided
4713 from Albert den Haan.

5718 fetching of the pointer
5719 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5720 copied from genNearPointerSet()
5721 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5722 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5723 If they pop r0/r1 they must be called in the opposite order than aopOp().
5724 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5725 (resp. --stack-auto), prepared for --xstack

5736 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5738 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5739 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5740 type for bits was changed. It resulted in bit variables becoming
5741 global, which is not permitted in PIC 14 assembly output.
5743 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5745 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5758 A few small changes that speed up the peephole optimizer.
5762 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5764 Try to make the peephole optimizer smarter by maintaining
5765 an association between the assembly source code and the
5766 iCodes that originated them. Put this information to use
5767 with a new peephole rule condition "notVolatile" so that
5768 the rules can be aggressive yet still safe.
5773 * src/mcs51/peeph.def
5775 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5779 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5780 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5781 if the left or right operand symbols have the accuse flag set.
5783 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5785 Changed the type of the result of the ! (NOT) operator to char;
5786 previously it returned the same type as the source. This allows
5787 us to eliminate all the genFloatNot functions (all of its target
5788 implementations were very buggy) since !float can use the same
5791 * src/SDCCicode.c (ast2iCode): ! returns char
5792 * src/mcs51/gen.c (genNot, genNotFloat),
5793 * src/ds390/gen.c (genNot, genNotFloat),
5794 * src/z80/gen.c (genNot, genNotFloat),
5795 * src/pic/gen.c (genNot, genNotFloat),
5796 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
5798 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5800 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5801 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5802 during interrupts. Ensure WSAVE is located at a shared bank address.
5803 2. Fixed page selection in some places
5804 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5805 the registers name strings.
5806 4. Fixed "signed / unsigned compare" compiler warnings.
5807 5. The PIC port manages its own allocation of the general purpose
5808 registers, but makes no attempt to reuse them. As a result when
5809 compiling it soon runs out of general purpose registers. Some
5810 additional code was added to the files pcode.c and device.c to walk
5811 through the function call tree and rename the registers so that they
5821 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5822 genPlus() & genMinus() when the result is the same as left or right

5828 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5830 Made bitfield a distinct type from bit so that bitfields
5831 convert as per ANSI C and bits retain their traditional
5832 boolean style behaviour. Implemented bitfield support in
5840 * src/ds390/gen.c: bit v bitfield split
5841 * src/z80/gen.c: New support for bitfields
5842 * support/regression/tests/bitfields.c: reenabled z80,
5845 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5847 Rules 246.x, 247.x relate to bitfields, the others speed up
5848 access to xdata mapped I/O devices.
5850 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5852 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5854 Cleaned up genPackBits and genUnpackBits and added two helper
5855 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5856 for literal assignments in genPackBits (thanks to Frieder for
5862 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5864 Fixed bug #748310 (pointer to function type mishandled when the
5865 function name is omitted). Also fixed a SIGSEGV when a function
5866 attribute (reentrant, etc) is used on a non-function or on a
5867 function but misplaced before the parameter list.
5869 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5871 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5872 * support/Util/SDCCerr.h,
5873 * support/Util/SDCCerr.c: Added func attr misuse error msg

5894 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5896 Made the constant following the "interrupt" keyword optional. If
5897 omitted, the function will not automatically be given an entry
5898 in the interrupt vector table (similar to #pragma NOIV, but
5899 less syntacticly kludgy). The interrupt number is also now
5900 range checked. Also fixed a bug in the high order bit example

5914 * src/SDCCicode.c (operandOperation): rewritten some ops
5915 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5916 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5918 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5919 be re-activated by defining REDUCE_LITERALS)
5920 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5921 unsigned, but are signed by default
5922 * src/SDCCval.c (constVal): rearranged
5923 * src/SDCCval.c (valMod): preliminary fix
5924 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6430 added if/endif conditional macros to remove options help
6431 messages from optionsTable when a port is not configured, added
6432 support for the PIc16 port in the ports table, when executing
6433 the compiler with no port specified on command line, a default
6434 port is selected with the new macro DEFAULT_PORT which is
6435 defined in port.h, in setDefaultOptions() linkOptions is removed
6436 from initialization assignment, since now it is a set,
6437 parseCmdLine uses setParseWithComma for linkOptions, in
6438 linkEdit() linkOptions are accessed with new function indexSet()
6439 which returns the i'th item of a set variable. See SDCCset.c, in
6440 linkEdit() when calling buildCmdLine(), added linkOptions as
6441 last argument. Now users can pass arguments to gplink via the
6442 -Wl option, main() uses pic16glue() to glue up pic16 programs

6456 gpasm complaining and test the linkage with gplink, _linkCmd and
6457 _asmCmd changed to be more gplink and gpasm friendly
6458 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6459 produced an error when parsed, peep rule 12 is added to utilize
6460 movff, but it is commented out since the pCode does not support
6461 yet a command with 2 address arguments
6463 2003-05-18 <johan AT balder>
6465 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6490 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6492 2003-05-11 Borut Razem <borut.razem AT siol.net>
6494 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6495 the path of bin directory, so that PATH is the only env. variable, which has to be set

7500 * src/SDCCicode.c: fixed array add
7502 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7503 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7504 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7506 2003-01-04 <johan AT balder>
7508 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7510 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7511 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7513 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

7523 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7524 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7526 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7528 * in \sdcc\as\mcs51\ changed these files in order to create an
7529 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7530 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7531 following files to include the previous two files: aslink.dsp,
7532 Makefile.aslink, Makefile.bcc, and Makefile.in.
7534 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7535 .adb instead of .cdb
7537 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7539 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7540 value from option --iram-size.
7542 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7544 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7547 2002-09-18 <wiml AT hhhh.org>
7549 * SDCClrange.h: exposed setFromRange() and setToRange()
7550 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7551 packRegsForAccUse() (bug 542397)
7552 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7553 multiple times and emitting the fetch operations more than once
7554 added aopGetUsesAcc() function to allow binary operators to
7555 fetch their operands in the correct order; made genMinus() emit
7556 compact code for X = LITERAL - Y
7558 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7559 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7560 sprintf() in line 1267.
7562 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7563 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7566 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7567 Changes to aslink (All the changes are marked with 'JCF'):
7569 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7572 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7573 area BSEG. Also moves, if possible, the DATA area down into the internal
7574 ram so more space is available.
7576 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7579 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7580 not bytes. Function summary() which creates a memory usage summary
7581 file with extension .mem. Reports of overlaping stack and small stack
7582 size. If the space for the stack is less than 16 bytes aslink trows a
7585 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7586 the 8051. Option 'y' for memory summary output file.
7588 Changes to sdcc (All the changes are marked with 'JCF'):
7590 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7592 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7593 overlaying area for it (uses RegBankUsed[4]).
7595 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7596 bank zero as used by default. By default aslink locates the stack
7597 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7598 the creation of the .mem file. Delegates the allocation of data area
7599 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7600 the begining of the stack area to aslink.
7602 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7603 glue() in SDCCglue.c creates an area for it.
7605 2002-09-03 Borut Razem <borut.razem AT siol.net>
7606 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7607 sdcc/src/pic/glue.c:
7608 introduced atexit() handler for teporay files removal in case of
7609 errors, assertions, ...
7611 2002-08-29 Borut Razem <borut.razem AT siol.net>
7612 * sdcc/support/cpp2/auto-host_vc_in.h:
7613 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7614 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7615 Maybe there is a similar problem with BORLANDC? It should be checked!
7617 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7618 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7619 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7620 was not executed, and the compiler (cl) launched a warning:
7621 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7623 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7624 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7626 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7627 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7629 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7630 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7631 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7632 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7633 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7634 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7635 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7636 - added Release configuration in VS projects
7637 - review of compiler an linker options
7638 - VC .exe files are generated in bin_vc directory, not to interfere
7639 with binaries generated from other projects (cygwin, mingw, bcc ...)
7641 * sdcc/src/yacc.dsp: added
7643 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7644 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7645 and insert the version number definitions from .version
7647 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7649 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7650 added - genarate auto-host.h using auto-host_vc_in.h as template
7653 removed from CVS, generated automatically
7655 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7656 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7658 2002-08-11 Borut Razem <borut.razem AT siol.net>
7659 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7661 2002-08-10 Borut Razem <borut.razem AT siol.net>
7662 * src/SDCCmain.c (main):
7663 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7664 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7665 The consequence was that some temporary files were not removed.
7668 unification of code in functions tempfilename() and tempfile():
7669 function tempnam() is defined in Visual Studio 6.0 and .NET
7671 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7673 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7674 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7675 - removed compiler command line option /WX: Treats all warnings as errors
7676 - update a list of source files, included into the project
7678 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7679 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7680 changed project type to Generic Project so that can be correcly converted to VS.NET project
7682 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7684 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7686 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7688 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7689 added return 0 statements after assert() to make compiler happy
7691 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7692 added newline in the def file to keep MSC compiler satisfied
7694 * sdcc/src/z80/gen.c:
7695 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7696 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7697 - solved MSC error in function aopDump()
7699 * sdcc_vc.h: define PREFIX as "\\sdcc"
7701 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7702 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7705 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7706 - Rewrote the register banking algorithm.
7707 - Added pCode live-range analysis to registers (for now, only non-used and
7708 singly-used registers optimized away)
7710 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7712 * 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.

7741 2002-03-28 Johan Knol <johan AT balder>
7743 * src/SDCCval.c: fixed bug #532436
7745 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7747 Added "char *Processor" field to the port structure.
7750 Added -p option. Allows port dependent processor to be specified.
7753 Initialized the new field char *Processor field to NULL in all ports
7756 Compiler generated registers for interrupt context saving
7757 were not getting allocated.
7759 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7762 Fixed left shift. Will promote the left side of a left shift
7763 if a) left shifting more than size of operand or b) when assigned
7764 to something size > size of left side
7766 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7768 tons of changes. Register allocation has been
7769 rewritten. Added customization for the various PICs. Flow
7770 analysis is restructured. ...
7776 Added. device.c is a PIC port hack to accomodate variations
7779 2002-03-13 Michael Hope <michaelh AT vroom>
7781 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

7878 not really partof a loop , but live ranges used in these blocks should
7879 be live thru the entire loop, so set partOfLoop but don't add them to
