454 prevent compiler warning
456 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
458 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
459 moved to level 0 and declared as static. Also they are explicit
460 placed in access bank. This was necessery because some times they
461 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
462 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
463 optimizations. Currently only compare to unsigned char is implemented,
464 * src/pic16/gen.c: added fReturnIdx array,
465 * (struct resolvedIfx) is moved to gen.h and made public,
466 * (struct _G): added sregsAlloc and sregsAllocSet fields,
467 * (aopForSym): added an optimization to directly store in stack of
468 the operand of a SEND iCode,
469 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
470 but as registers instead (AOP_REG) using the fReturnIdx array,
471 * (pic16_freeAsmop): remove the freed register from the
473 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
475 * (pic16_popGetTempRegCond): changed function prototype, now
476 function takes also a bitVector argument v which holds the current
477 set of registers that are allocated for stack access by aopForSym,
478 registers allocated in aopForSym for accessing stack symbols are not
479 any more part of the functions usedRegs field,
480 * (genCall): some times aopOp is called for a stack variable to be
481 send, aopForSym might perform the push, if this is true make sure
482 that genCall doesn't push the variable twice by testing _G.resDirect,
483 * (genFunction): changed testing for unspecified interrupt number
484 from 256 to INTNO_UNSPEC,
485 * modified selection scheme of frame pointer generation. Previously
486 if function did use local registers a frame pointer was generated,
487 now a frame pointer is generated only if function has arguments
488 (that need PLUSW2 register access), or has stack arguments, or the
489 compiler is not instructed to omit the frame pointer,
490 * (genEndFunction): before restoring local registers that were saved
491 in the function preamble, also restore the registers that *might*
492 have been allocated for stack access,
493 * (genRet): removed some old comments,
494 * (genCmp, the active (RN's) version): added a call to the
495 pic16_genCmp_special function to perform the compare with a more
496 robust and optimized way,
497 * (genInline): a feature has been added in inline code generation,
498 which allows a wildcard variable substitution when writing inline
499 assembly. Code is incomplete and experimental therefore undocumented,
500 * (genCast): changed order of aopOp for result and right to allow
501 aopForSym to directly load the result if possible,
502 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
503 perform an optimized compare on some selected special occasions,
504 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
505 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
506 generate an IVT any more,
507 * src/pic16/main.c (pic16_optionsTable): added command line option
509 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
510 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
512 * src/pic16/NOTES: Raphael Neider added in list of active developers
513 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
514 jumptable_end to prevent bug #,
515 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
516 inCond and outCond fields,
517 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
518 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
519 turn off register spilling,
520 * (packRegsForOneUse): synced with other ports' versions although it
521 is not used currently,
522 * (pic16_packRegisters): added an optimization while reading
523 structure bitfields, some registers may be saved (malloc code is
524 decreased by 80 bytes)
526 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
528 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
529 left is a bitfield, if yes, then don't optimize assignment. Perhaps
530 this can be optimized more?
532 2005-03-10 Raphael Neider <rneider AT web.de>
534 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
535 genNearPointerGet): (hopefully) fixed access to bitfields via
536 pointers (p->bitN = x; and x = p->bitN; failed)

1170 Adding support for replacing ljmps with sjmps in jumptables
1171 generated for switch statements. For now you need to set the
1172 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1173 Now 4 algorithms for mcs51 jumptable generation are used:
1174 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1175 addresses loaded pc-relative for up to 112 cases and stack-pushing
1176 target addresses loaded with offset from dptr for up to 256 cases.

1206 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1208 * added libc directory. The current version of LibC contains string
1209 functions, ctype functions and macros and some functions of the
1210 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1211 be extensively tested in the future. Standard disclaimer here.
1212 Library is not automatically build yet. But one can build it by

1224 * (pic16_storeForReturn): optimized return of 0,
1225 * (genCmp): experimental code for new genCmp which uses PIC18's
1226 special compare&skip instructions. Initial tests fail some times
1227 with variables grater than 1 byte in size, so new code is disabled,
1228 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1230 * (genCast): began a fix to optimize the casting of a bit to another
1231 bit, now assigning a bitfield to another bitfield will fail, sorry,

1240 and 1 for banking instruction,
1241 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1242 caused stop processing pCodes after a inline assembly block,
1243 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1245 registers when it shouldn't,
1246 * src/pic16/ralloc.c (allocReg): add preliminary support for
1247 supporting a limited set of temporary registers,
1249 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1254 (loadRegFromAop): recognize CLRH optimization,
1255 (genFunction): optimize RECEIVE iCodes in reentrant functions
1257 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1259 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4256 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4257 loaded with the linker search paths (-L arguments) and the libraries
4258 to be linked with the current source (-l arguments). Changes
4259 currently will affect only the pic16 port.
4260 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4261 include path the port specific paths and port specific libraries,
4262 * gplink command now contains the $3 argument,
4263 * src/pic16/device.h,
4264 * src/pic16/device.c,: structure PIC_device is made public and
4265 renamed to PIC16_device, the same for variable Pics which is renamed

4280 Documenting changes from previous commits.
4281 * configure.in (version 1.56),
4282 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4283 when generating output files to configure the pic16 library,
4284 but now I've commented it out, since gputils aren't installed in the
4285 SF compile farm, so library won't compile
4287 * device/lib/Makefile.in (version 1.56): initially I've added in
4288 target 'all' the prerequestive 'model-pic16' so it compiled the
4289 pic16 library, but now I've commented it out for the same reasons
4291 * added targets 'model-pic16' and 'objects-pic16' to compile the
4293 * added target 'port-specific-objects-pic16' to handle the
4294 generated libraries and copy them into the build/ directory
4295 * added target 'clean-intermediate-pic16' to clean intermediate
4296 files into pic16 directory
4297 * in target 'installdirs' added line to create directory pic16 in

4318 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4319 option so that it actually works. Made it specific to the z80, since
4320 the gbz80 doesn't have these kinds of I/O ports.
4322 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4324 * device/include/z180.h,

4348 via literal number. The symbol is placed in the corresponding
4349 position of the data ram
4350 * (pic16_dump_section): relocatable and absolute uninitialized
4351 data are now emitted in sorted order to reduce section naming,
4352 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4353 weren't marked as being in the access bank,

4546 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4548 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4549 (default behaviour).
4551 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4553 A python script to validate compiler diagnostic messages. It can be
4554 used to verify that sdcc complains about bad c source code and
4555 gives a good location of the error.
4556 * support/valdiag/Makefile,
4557 * support/valdiag/valdiag.py,
4558 * support/valdiag/tests/*

4577 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4579 * sdcc.spec: updated
4580 * device/include/Makefile.in: don't install CVS directories
4581 * device/lib/Makefile.in: added removal of CVS directories after install
4582 * doc/Makefile: fixed install, added local_icons
4583 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4584 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4585 * src/ds390/gen.c (genRightShift): fixed bug #870788

4588 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4590 PIC16 port related changes:
4591 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4592 added variable stackPos,
4594 * gen.c: genCall, assignResultValue: added support for
4595 pushing/retrieving function parameters to/from stack,
4596 genFunction,genEndFunction: setup stack frame for the
4598 genAddrOf: will be changed according to bug 863624
4600 * added files genutils.c and genutils.h which contain gen*
4601 debugged and optimised functions extracted from gen.c
4603 * glue.c: added variable 'externs' which holds extern symbols,
4604 pic16emitRegularMap: is modified to properly handle relocatable
4605 symbols under the new scheme,
4606 pic16createInterruptVect: is modified
4607 pic16printPublics: is modified to emit 'global' assembler directives,
4608 added pic16_printExterns to print extern symbols,
4609 pic16glue: initializes stack/frame pointer in the beginning of
4610 the assembly output. Temporary hack, will be corrected later,
4611 because gplink yet does not support stack and SDCC does not
4612 yet support a type of crt0.o object to create the final binary.
4614 * Removed many lines that contain 8051 legacy code.
4615 * The code is finally placed under a 'code' directive.
4616 * Added port specific options.
4618 * _process_pragma: simplified since now we do not need *special*
4619 include file to define SFR registers. But a separate header
4620 will be needed. This will be developed later.
4621 * _pic16_parseOptions: added, parses port specific options:
4622 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4623 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4624 --preplace-udata-with=
4626 * _pic16_setDefaultOptions: modified to initialize section names,
4627 but hack is temporarly out of order since it needs improvement.
4628 * _pic16_genAssemblerPreamble: configuration words are emitted by
4629 their address instead of their name. This part is incomplete and
4630 supports only the 18Fxx2 devices. Other devices will emit an error
4631 during assembly since they do not contain the same set of config
4633 * _pic16_genIVT: is modified,
4635 * pcode.c: added definitions for some hardware registers that are needed
4637 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4638 All PCI entries are updated. Now LFSR is supported.
4639 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4640 * added pic16_newpCodeOpLit2 to support instructions with
4641 two literal arguments
4642 * pic16_pCode2str: corrected code that emits assembler instructions
4643 with two literal operands and those that have an access bit modifier
4644 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4645 this fixes a bug which caused some labels to be lost, when an
4646 assembler directive was added, i.e. banksel,
4647 * pic16_FixRegisterBanking: improved logic that causes the insertion
4649 * InlineFunction: functions that are called once, are not any more
4650 inlined. This can be a port option in the future,
4652 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4654 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4655 hold the corresponding uninitialized symbols,
4656 * pic16_allocProcessorRegister: registers have explicit marked the
4658 * pic16_allocInternalRegister: registers are explicit marked as
4660 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4661 processing list, so bit registers were lost,
4664 * ralloc.h: added field 'accessBank' and original symbol operand
4665 in register definition,
4666 * removed the field isMapped from register definition,
4668 ** Several functions have been removed from various sources:
4669 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4670 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4671 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4672 pic16_assignRelocatableRegisters
4674 ** others have been introduced:
4675 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4676 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4678 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4680 * support/scripts/inc2h.pl: changed definition of BIT_AT
4681 to emit 'sbit at' instead of 'bit at'. This was a request.
4683 PIC16 port related preliminary changes:
4684 * gen.c: prefixed function popRegFromString with
4685 pic16_ and all references to it corrected
4686 * pcode.c: all pic16_pc_* hardware registers prefixed
4687 with underscore (_),
4688 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4689 * ralloc.c: newReg(): when register is REG_SFR then
4690 set address to rIdx,
4691 pic16_allocProcessorRegister(): marks register wasUsed=0
4692 pic16_writeUsedRegs(): added a call to assign processor
4693 registers via pic16_assignFixedRegisters
4695 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4697 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4698 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4699 variables in unused register banks. Also the SSEG is placed
4700 wherever there is enough space for it, and IDATA can be anywhere
4701 in internal RAM. For now compile using -Wl-Y[stack_size].
4702 The mem file is different for this option as well, since it
4703 makes no sense of talking about DSEG lenght.
4705 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4707 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4708 in certain cases, e.g. when ROM assignment, patch provided
4709 from Albert den Haan.

5714 fetching of the pointer
5715 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5716 copied from genNearPointerSet()
5717 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5718 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5732 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5734 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5735 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5736 type for bits was changed. It resulted in bit variables becoming
5737 global, which is not permitted in PIC 14 assembly output.
5739 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5741 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5754 A few small changes that speed up the peephole optimizer.
5758 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5760 Try to make the peephole optimizer smarter by maintaining
5761 an association between the assembly source code and the
5762 iCodes that originated them. Put this information to use
5763 with a new peephole rule condition "notVolatile" so that
5764 the rules can be aggressive yet still safe.
5769 * src/mcs51/peeph.def
5771 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5775 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5776 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5777 if the left or right operand symbols have the accuse flag set.
5779 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5781 Changed the type of the result of the ! (NOT) operator to char;
5782 previously it returned the same type as the source. This allows
5783 us to eliminate all the genFloatNot functions (all of its target
5784 implementations were very buggy) since !float can use the same
5787 * src/SDCCicode.c (ast2iCode): ! returns char
5788 * src/mcs51/gen.c (genNot, genNotFloat),
5789 * src/ds390/gen.c (genNot, genNotFloat),
5790 * src/z80/gen.c (genNot, genNotFloat),
5791 * src/pic/gen.c (genNot, genNotFloat),
5792 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
5794 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5796 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5797 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5798 during interrupts. Ensure WSAVE is located at a shared bank address.
5799 2. Fixed page selection in some places
5800 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5801 the registers name strings.
5802 4. Fixed "signed / unsigned compare" compiler warnings.
5803 5. The PIC port manages its own allocation of the general purpose
5804 registers, but makes no attempt to reuse them. As a result when
5805 compiling it soon runs out of general purpose registers. Some
5806 additional code was added to the files pcode.c and device.c to walk
5807 through the function call tree and rename the registers so that they
5817 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5818 genPlus() & genMinus() when the result is the same as left or right
5820 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5824 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5826 Made bitfield a distinct type from bit so that bitfields
5827 convert as per ANSI C and bits retain their traditional
5828 boolean style behaviour. Implemented bitfield support in
5836 * src/ds390/gen.c: bit v bitfield split
5837 * src/z80/gen.c: New support for bitfields
5838 * support/regression/tests/bitfields.c: reenabled z80,
5841 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5843 Rules 246.x, 247.x relate to bitfields, the others speed up
5844 access to xdata mapped I/O devices.
5846 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5848 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5850 Cleaned up genPackBits and genUnpackBits and added two helper
5851 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5852 for literal assignments in genPackBits (thanks to Frieder for
5858 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5860 Fixed bug #748310 (pointer to function type mishandled when the
5861 function name is omitted). Also fixed a SIGSEGV when a function
5862 attribute (reentrant, etc) is used on a non-function or on a
5863 function but misplaced before the parameter list.
5865 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5867 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5868 * support/Util/SDCCerr.h,
5869 * support/Util/SDCCerr.c: Added func attr misuse error msg
5871 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5873 Fixed bug #787649 by anonymous
5874 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

5890 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5892 Made the constant following the "interrupt" keyword optional. If
5893 omitted, the function will not automatically be given an entry
5894 in the interrupt vector table (similar to #pragma NOIV, but
5895 less syntacticly kludgy). The interrupt number is also now
5896 range checked. Also fixed a bug in the high order bit example

5912 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5914 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5915 be re-activated by defining REDUCE_LITERALS)
5916 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5917 unsigned, but are signed by default
5918 * src/SDCCval.c (constVal): rearranged
5919 * src/SDCCval.c (valMod): preliminary fix
5920 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6426 added if/endif conditional macros to remove options help
6427 messages from optionsTable when a port is not configured, added
6428 support for the PIc16 port in the ports table, when executing
6429 the compiler with no port specified on command line, a default
6430 port is selected with the new macro DEFAULT_PORT which is
6431 defined in port.h, in setDefaultOptions() linkOptions is removed
6432 from initialization assignment, since now it is a set,
6433 parseCmdLine uses setParseWithComma for linkOptions, in
6434 linkEdit() linkOptions are accessed with new function indexSet()
6435 which returns the i'th item of a set variable. See SDCCset.c, in
6436 linkEdit() when calling buildCmdLine(), added linkOptions as
6437 last argument. Now users can pass arguments to gplink via the
6438 -Wl option, main() uses pic16glue() to glue up pic16 programs

6452 gpasm complaining and test the linkage with gplink, _linkCmd and
6453 _asmCmd changed to be more gplink and gpasm friendly
6454 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6455 produced an error when parsed, peep rule 12 is added to utilize
6456 movff, but it is commented out since the pCode does not support
6457 yet a command with 2 address arguments
6459 2003-05-18 <johan AT balder>
6461 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6484 2003-05-12 Borut Razem <borut.razem AT siol.net>
6486 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6488 2003-05-11 Borut Razem <borut.razem AT siol.net>
6490 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6491 the path of bin directory, so that PATH is the only env. variable, which has to be set
6492 in case of standard installation.

7496 * src/SDCCicode.c: fixed array add
7498 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7499 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7500 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7502 2003-01-04 <johan AT balder>
7504 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7506 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7507 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7509 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

7519 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7520 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7522 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7524 * in \sdcc\as\mcs51\ changed these files in order to create an
7525 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7526 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7527 following files to include the previous two files: aslink.dsp,
7528 Makefile.aslink, Makefile.bcc, and Makefile.in.
7530 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7531 .adb instead of .cdb
7533 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7535 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7536 value from option --iram-size.
7538 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7540 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7543 2002-09-18 <wiml AT hhhh.org>
7545 * SDCClrange.h: exposed setFromRange() and setToRange()
7546 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7547 packRegsForAccUse() (bug 542397)
7548 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7549 multiple times and emitting the fetch operations more than once
7550 added aopGetUsesAcc() function to allow binary operators to
7551 fetch their operands in the correct order; made genMinus() emit
7552 compact code for X = LITERAL - Y
7554 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7555 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7556 sprintf() in line 1267.
7558 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7559 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7562 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7563 Changes to aslink (All the changes are marked with 'JCF'):
7565 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7568 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7569 area BSEG. Also moves, if possible, the DATA area down into the internal
7570 ram so more space is available.
7572 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7575 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7576 not bytes. Function summary() which creates a memory usage summary
7577 file with extension .mem. Reports of overlaping stack and small stack
7578 size. If the space for the stack is less than 16 bytes aslink trows a
7581 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7582 the 8051. Option 'y' for memory summary output file.
7584 Changes to sdcc (All the changes are marked with 'JCF'):
7586 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7588 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7589 overlaying area for it (uses RegBankUsed[4]).
7591 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7592 bank zero as used by default. By default aslink locates the stack
7593 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7594 the creation of the .mem file. Delegates the allocation of data area
7595 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7596 the begining of the stack area to aslink.
7598 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7599 glue() in SDCCglue.c creates an area for it.
7601 2002-09-03 Borut Razem <borut.razem AT siol.net>
7602 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7603 sdcc/src/pic/glue.c:
7604 introduced atexit() handler for teporay files removal in case of
7605 errors, assertions, ...
7607 2002-08-29 Borut Razem <borut.razem AT siol.net>
7608 * sdcc/support/cpp2/auto-host_vc_in.h:
7609 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7610 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7611 Maybe there is a similar problem with BORLANDC? It should be checked!
7613 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7614 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7615 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7616 was not executed, and the compiler (cl) launched a warning:
7617 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7619 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7620 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7622 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7623 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7625 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7626 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7627 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7628 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7629 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7630 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7631 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7632 - added Release configuration in VS projects
7633 - review of compiler an linker options
7634 - VC .exe files are generated in bin_vc directory, not to interfere
7635 with binaries generated from other projects (cygwin, mingw, bcc ...)
7637 * sdcc/src/yacc.dsp: added
7639 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7640 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7641 and insert the version number definitions from .version
7643 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7645 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7646 added - genarate auto-host.h using auto-host_vc_in.h as template
7649 removed from CVS, generated automatically
7651 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7652 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7654 2002-08-11 Borut Razem <borut.razem AT siol.net>
7655 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7657 2002-08-10 Borut Razem <borut.razem AT siol.net>
7658 * src/SDCCmain.c (main):
7659 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7660 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7661 The consequence was that some temporary files were not removed.
7664 unification of code in functions tempfilename() and tempfile():
7665 function tempnam() is defined in Visual Studio 6.0 and .NET
7667 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7669 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7670 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7671 - removed compiler command line option /WX: Treats all warnings as errors
7672 - update a list of source files, included into the project
7674 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7675 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7676 changed project type to Generic Project so that can be correcly converted to VS.NET project
7678 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7680 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7682 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7684 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7685 added return 0 statements after assert() to make compiler happy
7687 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7688 added newline in the def file to keep MSC compiler satisfied
7690 * sdcc/src/z80/gen.c:
7691 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7692 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7693 - solved MSC error in function aopDump()
7695 * sdcc_vc.h: define PREFIX as "\\sdcc"
7697 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7698 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7704 singly-used registers optimized away)
7706 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7708 * 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.

7737 2002-03-28 Johan Knol <johan AT balder>
7739 * src/SDCCval.c: fixed bug #532436
7741 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7743 Added "char *Processor" field to the port structure.
7746 Added -p option. Allows port dependent processor to be specified.
7749 Initialized the new field char *Processor field to NULL in all ports
7752 Compiler generated registers for interrupt context saving
7753 were not getting allocated.
7755 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7758 Fixed left shift. Will promote the left side of a left shift
7759 if a) left shifting more than size of operand or b) when assigned
7760 to something size > size of left side
7762 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7764 tons of changes. Register allocation has been
7765 rewritten. Added customization for the various PICs. Flow
7766 analysis is restructured. ...
7772 Added. device.c is a PIC port hack to accomodate variations
7775 2002-03-13 Michael Hope <michaelh AT vroom>
7777 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

7874 not really partof a loop , but live ranges used in these blocks should
7875 be live thru the entire loop, so set partOfLoop but don't add them to
