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

1166 generated for switch statements. For now you need to set the
1167 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1168 Now 4 algorithms for mcs51 jumptable generation are used:
1169 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

1203 * added libc directory. The current version of LibC contains string
1204 functions, ctype functions and macros and some functions of the
1205 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1206 be extensively tested in the future. Standard disclaimer here.

1219 * (pic16_storeForReturn): optimized return of 0,
1220 * (genCmp): experimental code for new genCmp which uses PIC18's
1221 special compare&skip instructions. Initial tests fail some times
1222 with variables grater than 1 byte in size, so new code is disabled,
1223 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1225 * (genCast): began a fix to optimize the casting of a bit to another
1226 bit, now assigning a bitfield to another bitfield will fail, sorry,

1235 and 1 for banking instruction,
1236 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1237 caused stop processing pCodes after a inline assembly block,
1238 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1240 registers when it shouldn't,
1241 * src/pic16/ralloc.c (allocReg): add preliminary support for
1242 supporting a limited set of temporary registers,
1244 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1250 (genFunction): optimize RECEIVE iCodes in reentrant functions
1252 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4251 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4252 loaded with the linker search paths (-L arguments) and the libraries
4253 to be linked with the current source (-l arguments). Changes
4254 currently will affect only the pic16 port.
4255 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4256 include path the port specific paths and port specific libraries,
4257 * gplink command now contains the $3 argument,
4258 * src/pic16/device.h,
4259 * src/pic16/device.c,: structure PIC_device is made public and

4275 Documenting changes from previous commits.
4276 * configure.in (version 1.56),
4277 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4278 when generating output files to configure the pic16 library,
4279 but now I've commented it out, since gputils aren't installed in the
4280 SF compile farm, so library won't compile
4282 * device/lib/Makefile.in (version 1.56): initially I've added in
4283 target 'all' the prerequestive 'model-pic16' so it compiled the
4284 pic16 library, but now I've commented it out for the same reasons
4286 * added targets 'model-pic16' and 'objects-pic16' to compile the
4288 * added target 'port-specific-objects-pic16' to handle the
4289 generated libraries and copy them into the build/ directory
4290 * added target 'clean-intermediate-pic16' to clean intermediate
4291 files into pic16 directory
4292 * in target 'installdirs' added line to create directory pic16 in

4313 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4314 option so that it actually works. Made it specific to the z80, since
4315 the gbz80 doesn't have these kinds of I/O ports.
4317 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4319 * device/include/z180.h,

4343 via literal number. The symbol is placed in the corresponding
4344 position of the data ram
4345 * (pic16_dump_section): relocatable and absolute uninitialized
4346 data are now emitted in sorted order to reduce section naming,
4347 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4348 weren't marked as being in the access bank,

4541 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4543 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4544 (default behaviour).
4546 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4548 A python script to validate compiler diagnostic messages. It can be
4549 used to verify that sdcc complains about bad c source code and
4550 gives a good location of the error.
4551 * support/valdiag/Makefile,
4552 * support/valdiag/valdiag.py,

4572 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4574 * sdcc.spec: updated
4575 * device/include/Makefile.in: don't install CVS directories

4583 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4585 PIC16 port related changes:
4586 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4587 added variable stackPos,
4589 * gen.c: genCall, assignResultValue: added support for
4590 pushing/retrieving function parameters to/from stack,
4591 genFunction,genEndFunction: setup stack frame for the
4593 genAddrOf: will be changed according to bug 863624
4595 * added files genutils.c and genutils.h which contain gen*
4596 debugged and optimised functions extracted from gen.c
4598 * glue.c: added variable 'externs' which holds extern symbols,
4599 pic16emitRegularMap: is modified to properly handle relocatable
4600 symbols under the new scheme,
4601 pic16createInterruptVect: is modified
4602 pic16printPublics: is modified to emit 'global' assembler directives,
4603 added pic16_printExterns to print extern symbols,
4604 pic16glue: initializes stack/frame pointer in the beginning of
4605 the assembly output. Temporary hack, will be corrected later,
4606 because gplink yet does not support stack and SDCC does not
4607 yet support a type of crt0.o object to create the final binary.
4609 * Removed many lines that contain 8051 legacy code.
4610 * The code is finally placed under a 'code' directive.
4611 * Added port specific options.
4613 * _process_pragma: simplified since now we do not need *special*
4614 include file to define SFR registers. But a separate header
4615 will be needed. This will be developed later.
4616 * _pic16_parseOptions: added, parses port specific options:
4617 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4618 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4619 --preplace-udata-with=
4621 * _pic16_setDefaultOptions: modified to initialize section names,
4622 but hack is temporarly out of order since it needs improvement.
4623 * _pic16_genAssemblerPreamble: configuration words are emitted by
4624 their address instead of their name. This part is incomplete and
4625 supports only the 18Fxx2 devices. Other devices will emit an error
4626 during assembly since they do not contain the same set of config
4628 * _pic16_genIVT: is modified,
4630 * pcode.c: added definitions for some hardware registers that are needed
4632 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4633 All PCI entries are updated. Now LFSR is supported.
4634 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4635 * added pic16_newpCodeOpLit2 to support instructions with
4636 two literal arguments
4637 * pic16_pCode2str: corrected code that emits assembler instructions
4638 with two literal operands and those that have an access bit modifier
4639 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4640 this fixes a bug which caused some labels to be lost, when an
4641 assembler directive was added, i.e. banksel,
4642 * pic16_FixRegisterBanking: improved logic that causes the insertion
4644 * InlineFunction: functions that are called once, are not any more
4645 inlined. This can be a port option in the future,
4647 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4649 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4650 hold the corresponding uninitialized symbols,
4651 * pic16_allocProcessorRegister: registers have explicit marked the
4653 * pic16_allocInternalRegister: registers are explicit marked as
4655 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4656 processing list, so bit registers were lost,
4659 * ralloc.h: added field 'accessBank' and original symbol operand
4660 in register definition,
4661 * removed the field isMapped from register definition,
4663 ** Several functions have been removed from various sources:
4664 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4665 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4666 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4667 pic16_assignRelocatableRegisters
4669 ** others have been introduced:
4670 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4671 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4673 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4675 * support/scripts/inc2h.pl: changed definition of BIT_AT
4676 to emit 'sbit at' instead of 'bit at'. This was a request.
4678 PIC16 port related preliminary changes:
4679 * gen.c: prefixed function popRegFromString with
4680 pic16_ and all references to it corrected
4681 * pcode.c: all pic16_pc_* hardware registers prefixed
4682 with underscore (_),
4683 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4684 * ralloc.c: newReg(): when register is REG_SFR then
4685 set address to rIdx,
4686 pic16_allocProcessorRegister(): marks register wasUsed=0
4687 pic16_writeUsedRegs(): added a call to assign processor
4688 registers via pic16_assignFixedRegisters
4690 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4692 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4693 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4694 variables in unused register banks. Also the SSEG is placed
4695 wherever there is enough space for it, and IDATA can be anywhere
4696 in internal RAM. For now compile using -Wl-Y[stack_size].
4697 The mem file is different for this option as well, since it
4698 makes no sense of talking about DSEG lenght.
4700 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4702 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4703 in certain cases, e.g. when ROM assignment, patch provided
4704 from Albert den Haan.
4706 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5709 fetching of the pointer
5710 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5711 copied from genNearPointerSet()
5712 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5713 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5727 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5729 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5730 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5731 type for bits was changed. It resulted in bit variables becoming
5732 global, which is not permitted in PIC 14 assembly output.
5734 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5736 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5749 A few small changes that speed up the peephole optimizer.
5753 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5755 Try to make the peephole optimizer smarter by maintaining
5756 an association between the assembly source code and the
5757 iCodes that originated them. Put this information to use
5758 with a new peephole rule condition "notVolatile" so that
5759 the rules can be aggressive yet still safe.
5764 * src/mcs51/peeph.def
5766 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5770 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5771 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5772 if the left or right operand symbols have the accuse flag set.
5774 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5776 Changed the type of the result of the ! (NOT) operator to char;
5777 previously it returned the same type as the source. This allows
5778 us to eliminate all the genFloatNot functions (all of its target
5779 implementations were very buggy) since !float can use the same
5782 * src/SDCCicode.c (ast2iCode): ! returns char
5783 * src/mcs51/gen.c (genNot, genNotFloat),
5784 * src/ds390/gen.c (genNot, genNotFloat),
5785 * src/z80/gen.c (genNot, genNotFloat),
5786 * src/pic/gen.c (genNot, genNotFloat),
5787 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
5789 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5791 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5792 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5793 during interrupts. Ensure WSAVE is located at a shared bank address.
5794 2. Fixed page selection in some places
5795 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5796 the registers name strings.
5797 4. Fixed "signed / unsigned compare" compiler warnings.
5798 5. The PIC port manages its own allocation of the general purpose
5799 registers, but makes no attempt to reuse them. As a result when
5800 compiling it soon runs out of general purpose registers. Some
5801 additional code was added to the files pcode.c and device.c to walk
5802 through the function call tree and rename the registers so that they
5812 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5813 genPlus() & genMinus() when the result is the same as left or right
5815 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5819 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5821 Made bitfield a distinct type from bit so that bitfields
5822 convert as per ANSI C and bits retain their traditional
5823 boolean style behaviour. Implemented bitfield support in
5831 * src/ds390/gen.c: bit v bitfield split
5832 * src/z80/gen.c: New support for bitfields
5833 * support/regression/tests/bitfields.c: reenabled z80,
5836 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5838 Rules 246.x, 247.x relate to bitfields, the others speed up
5839 access to xdata mapped I/O devices.
5841 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5843 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5845 Cleaned up genPackBits and genUnpackBits and added two helper
5846 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5847 for literal assignments in genPackBits (thanks to Frieder for
5853 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5855 Fixed bug #748310 (pointer to function type mishandled when the
5856 function name is omitted). Also fixed a SIGSEGV when a function
5857 attribute (reentrant, etc) is used on a non-function or on a
5858 function but misplaced before the parameter list.
5860 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5862 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5863 * support/Util/SDCCerr.h,
5864 * support/Util/SDCCerr.c: Added func attr misuse error msg

5885 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5887 Made the constant following the "interrupt" keyword optional. If
5888 omitted, the function will not automatically be given an entry
5889 in the interrupt vector table (similar to #pragma NOIV, but
5890 less syntacticly kludgy). The interrupt number is also now
5891 range checked. Also fixed a bug in the high order bit example

5902 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5904 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
5905 * src/SDCCicode.c (operandOperation): rewritten some ops
5906 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5907 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5909 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5910 be re-activated by defining REDUCE_LITERALS)
5911 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5912 unsigned, but are signed by default
5913 * src/SDCCval.c (constVal): rearranged
5914 * src/SDCCval.c (valMod): preliminary fix
5915 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6421 added if/endif conditional macros to remove options help
6422 messages from optionsTable when a port is not configured, added
6423 support for the PIc16 port in the ports table, when executing
6424 the compiler with no port specified on command line, a default
6425 port is selected with the new macro DEFAULT_PORT which is
6426 defined in port.h, in setDefaultOptions() linkOptions is removed
6427 from initialization assignment, since now it is a set,
6428 parseCmdLine uses setParseWithComma for linkOptions, in
6429 linkEdit() linkOptions are accessed with new function indexSet()
6430 which returns the i'th item of a set variable. See SDCCset.c, in
6431 linkEdit() when calling buildCmdLine(), added linkOptions as
6432 last argument. Now users can pass arguments to gplink via the
6433 -Wl option, main() uses pic16glue() to glue up pic16 programs

6447 gpasm complaining and test the linkage with gplink, _linkCmd and
6448 _asmCmd changed to be more gplink and gpasm friendly
6449 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6450 produced an error when parsed, peep rule 12 is added to utilize
6451 movff, but it is commented out since the pCode does not support
6452 yet a command with 2 address arguments
6454 2003-05-18 <johan AT balder>
6456 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6483 2003-05-11 Borut Razem <borut.razem AT siol.net>
6485 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

7474 2003-01-07 <johan AT balder>
7476 * src/SDCCast.c (decorateType): fixed bug #600035
7478 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>

7489 2003-01-06 <johan AT balder>
7491 * src/SDCCicode.c: fixed array add
7493 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7494 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7495 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7497 2003-01-04 <johan AT balder>
7499 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7501 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7502 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7504 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7505 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

7511 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7512 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7514 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7515 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7517 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7519 * in \sdcc\as\mcs51\ changed these files in order to create an
7520 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7521 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7522 following files to include the previous two files: aslink.dsp,
7523 Makefile.aslink, Makefile.bcc, and Makefile.in.
7525 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7526 .adb instead of .cdb
7528 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7530 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7531 value from option --iram-size.
7533 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7535 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7538 2002-09-18 <wiml AT hhhh.org>
7540 * SDCClrange.h: exposed setFromRange() and setToRange()
7541 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7542 packRegsForAccUse() (bug 542397)
7543 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7544 multiple times and emitting the fetch operations more than once
7545 added aopGetUsesAcc() function to allow binary operators to
7546 fetch their operands in the correct order; made genMinus() emit
7547 compact code for X = LITERAL - Y
7549 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7550 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7551 sprintf() in line 1267.
7553 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7554 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7557 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7558 Changes to aslink (All the changes are marked with 'JCF'):
7560 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7563 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7564 area BSEG. Also moves, if possible, the DATA area down into the internal
7565 ram so more space is available.
7567 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7570 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7571 not bytes. Function summary() which creates a memory usage summary
7572 file with extension .mem. Reports of overlaping stack and small stack
7573 size. If the space for the stack is less than 16 bytes aslink trows a
7576 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7577 the 8051. Option 'y' for memory summary output file.
7579 Changes to sdcc (All the changes are marked with 'JCF'):
7581 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7583 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7584 overlaying area for it (uses RegBankUsed[4]).
7586 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7587 bank zero as used by default. By default aslink locates the stack
7588 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7589 the creation of the .mem file. Delegates the allocation of data area
7590 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7591 the begining of the stack area to aslink.
7593 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7594 glue() in SDCCglue.c creates an area for it.
7596 2002-09-03 Borut Razem <borut.razem AT siol.net>
7597 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7598 sdcc/src/pic/glue.c:
7599 introduced atexit() handler for teporay files removal in case of
7600 errors, assertions, ...
7602 2002-08-29 Borut Razem <borut.razem AT siol.net>
7603 * sdcc/support/cpp2/auto-host_vc_in.h:
7604 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7605 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7606 Maybe there is a similar problem with BORLANDC? It should be checked!
7608 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7609 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7610 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7611 was not executed, and the compiler (cl) launched a warning:
7612 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7614 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7615 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7617 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7618 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7620 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7621 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7622 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7623 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7624 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7625 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7626 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7627 - added Release configuration in VS projects
7628 - review of compiler an linker options
7629 - VC .exe files are generated in bin_vc directory, not to interfere
7630 with binaries generated from other projects (cygwin, mingw, bcc ...)
7632 * sdcc/src/yacc.dsp: added
7634 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7635 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7636 and insert the version number definitions from .version
7638 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7640 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7641 added - genarate auto-host.h using auto-host_vc_in.h as template
7644 removed from CVS, generated automatically
7646 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7647 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7649 2002-08-11 Borut Razem <borut.razem AT siol.net>
7650 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7652 2002-08-10 Borut Razem <borut.razem AT siol.net>
7653 * src/SDCCmain.c (main):
7654 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7655 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7656 The consequence was that some temporary files were not removed.
7659 unification of code in functions tempfilename() and tempfile():
7660 function tempnam() is defined in Visual Studio 6.0 and .NET
7662 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7664 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7665 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7666 - removed compiler command line option /WX: Treats all warnings as errors
7667 - update a list of source files, included into the project
7669 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7670 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7671 changed project type to Generic Project so that can be correcly converted to VS.NET project
7673 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7675 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7677 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7679 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7680 added return 0 statements after assert() to make compiler happy
7682 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7683 added newline in the def file to keep MSC compiler satisfied
7685 * sdcc/src/z80/gen.c:
7686 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7687 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7688 - solved MSC error in function aopDump()
7690 * sdcc_vc.h: define PREFIX as "\\sdcc"
7692 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7693 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7695 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7696 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7697 - Rewrote the register banking algorithm.
7698 - Added pCode live-range analysis to registers (for now, only non-used and
7699 singly-used registers optimized away)
7701 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7703 * 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.

7728 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7730 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7732 2002-03-28 Johan Knol <johan AT balder>
7734 * src/SDCCval.c: fixed bug #532436
7736 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7738 Added "char *Processor" field to the port structure.
7741 Added -p option. Allows port dependent processor to be specified.
7744 Initialized the new field char *Processor field to NULL in all ports
7747 Compiler generated registers for interrupt context saving
7748 were not getting allocated.
7750 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7753 Fixed left shift. Will promote the left side of a left shift
7754 if a) left shifting more than size of operand or b) when assigned
7755 to something size > size of left side
7757 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7759 tons of changes. Register allocation has been
7760 rewritten. Added customization for the various PICs. Flow
7761 analysis is restructured. ...
7767 Added. device.c is a PIC port hack to accomodate variations
7770 2002-03-13 Michael Hope <michaelh AT vroom>
7772 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7774 2002-03-04 johanknol <johanknol AT manik>
7776 * /src/SDCCval.c: fixed
7778 const unsigned char arr[][2] = { { 0, 1 } };
7779 t18.c:1: error: Initializer element is not constant
7781 2002-03-04 bela <bela AT manik>
7783 * /device/include/mcs51reg.h:
7784 ds89c420 register definition update
7786 2002-03-03 <johan AT FRIJA>

7865 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7867 * sdcc/src/SDCCloop.c:
7868 Previous fix was not good. basic blocks that have "break" or "return" are
7869 not really partof a loop , but live ranges used in these blocks should
7870 be live thru the entire loop, so set partOfLoop but don't add them to
7873 2002-02-21 <johan AT FRIJA>
7875 * src/SDCCcse.c: fixed bug #514308
7877 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
