420 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
422 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
423 moved to level 0 and declared as static. Also they are explicit
424 placed in access bank. This was necessery because some times they
425 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!

439 * (pic16_popGetTempRegCond): changed function prototype, now
440 function takes also a bitVector argument v which holds the current
441 set of registers that are allocated for stack access by aopForSym,
442 registers allocated in aopForSym for accessing stack symbols are not
443 any more part of the functions usedRegs field,
444 * (genCall): some times aopOp is called for a stack variable to be
445 send, aopForSym might perform the push, if this is true make sure
446 that genCall doesn't push the variable twice by testing _G.resDirect,
447 * (genFunction): changed testing for unspecified interrupt number
448 from 256 to INTNO_UNSPEC,
449 * modified selection scheme of frame pointer generation. Previously
450 if function did use local registers a frame pointer was generated,
451 now a frame pointer is generated only if function has arguments
452 (that need PLUSW2 register access), or has stack arguments, or the
453 compiler is not instructed to omit the frame pointer,
454 * (genEndFunction): before restoring local registers that were saved
455 in the function preamble, also restore the registers that *might*
456 have been allocated for stack access,
457 * (genRet): removed some old comments,
458 * (genCmp, the active (RN's) version): added a call to the
459 pic16_genCmp_special function to perform the compare with a more
460 robust and optimized way,
461 * (genInline): a feature has been added in inline code generation,
462 which allows a wildcard variable substitution when writing inline
463 assembly. Code is incomplete and experimental therefore undocumented,
464 * (genCast): changed order of aopOp for result and right to allow
465 aopForSym to directly load the result if possible,
466 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
467 perform an optimized compare on some selected special occasions,
468 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
469 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
470 generate an IVT any more,
471 * src/pic16/main.c (pic16_optionsTable): added command line option
473 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
474 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
476 * src/pic16/NOTES: Raphael Neider added in list of active developers
477 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
478 jumptable_end to prevent bug #,
479 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
480 inCond and outCond fields,
481 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
482 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
483 turn off register spilling,
484 * (packRegsForOneUse): synced with other ports' versions although it
485 is not used currently,
486 * (pic16_packRegisters): added an optimization while reading
487 structure bitfields, some registers may be saved (malloc code is
488 decreased by 80 bytes)
490 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
492 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
493 left is a bitfield, if yes, then don't optimize assignment. Perhaps
494 this can be optimized more?
496 2005-03-10 Raphael Neider <rneider AT web.de>
498 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
499 genNearPointerGet): (hopefully) fixed access to bitfields via
500 pointers (p->bitN = x; and x = p->bitN; failed)

1134 Adding support for replacing ljmps with sjmps in jumptables
1135 generated for switch statements. For now you need to set the
1136 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1137 Now 4 algorithms for mcs51 jumptable generation are used:
1138 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1139 addresses loaded pc-relative for up to 112 cases and stack-pushing
1140 target addresses loaded with offset from dptr for up to 256 cases.

1170 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1172 * added libc directory. The current version of LibC contains string
1173 functions, ctype functions and macros and some functions of the
1174 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1175 be extensively tested in the future. Standard disclaimer here.
1176 Library is not automatically build yet. But one can build it by
1177 invoking 'make' inside the libc directory.

1188 * (pic16_storeForReturn): optimized return of 0,
1189 * (genCmp): experimental code for new genCmp which uses PIC18's
1190 special compare&skip instructions. Initial tests fail some times
1191 with variables grater than 1 byte in size, so new code is disabled,
1192 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1194 * (genCast): began a fix to optimize the casting of a bit to another
1195 bit, now assigning a bitfield to another bitfield will fail, sorry,

1204 and 1 for banking instruction,
1205 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1206 caused stop processing pCodes after a inline assembly block,
1207 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1209 registers when it shouldn't,
1210 * src/pic16/ralloc.c (allocReg): add preliminary support for
1211 supporting a limited set of temporary registers,
1213 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1219 (genFunction): optimize RECEIVE iCodes in reentrant functions
1221 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4221 loaded with the linker search paths (-L arguments) and the libraries
4222 to be linked with the current source (-l arguments). Changes
4223 currently will affect only the pic16 port.
4224 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4225 include path the port specific paths and port specific libraries,
4226 * gplink command now contains the $3 argument,
4227 * src/pic16/device.h,

4244 Documenting changes from previous commits.
4245 * configure.in (version 1.56),
4246 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4247 when generating output files to configure the pic16 library,
4248 but now I've commented it out, since gputils aren't installed in the
4249 SF compile farm, so library won't compile
4251 * device/lib/Makefile.in (version 1.56): initially I've added in
4252 target 'all' the prerequestive 'model-pic16' so it compiled the
4253 pic16 library, but now I've commented it out for the same reasons
4255 * added targets 'model-pic16' and 'objects-pic16' to compile the
4257 * added target 'port-specific-objects-pic16' to handle the
4258 generated libraries and copy them into the build/ directory
4259 * added target 'clean-intermediate-pic16' to clean intermediate
4260 files into pic16 directory
4261 * in target 'installdirs' added line to create directory pic16 in

4265 added lines to copy all header files to installation path,
4266 * in target 'installdirs' added line create directory for pic16
4267 headers in the installation path

4472 arguments via -W option
4473 * src/pic16/main.c: added $l in _asmCmd, changed extension for
4474 object file from '.rel' to '.o' in port->linker structure,

4506 * src/SDCCast.c (decorateType),
4507 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
4508 LEFT_OP (left shift)
4510 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4512 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4513 (default behaviour).
4515 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4517 A python script to validate compiler diagnostic messages. It can be
4518 used to verify that sdcc complains about bad c source code and
4519 gives a good location of the error.
4520 * support/valdiag/Makefile,
4521 * support/valdiag/valdiag.py,
4522 * support/valdiag/tests/*

4539 Bug reported from Jesus Calvino-Fraga
4541 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4543 * sdcc.spec: updated
4544 * device/include/Makefile.in: don't install CVS directories
4545 * device/lib/Makefile.in: added removal of CVS directories after install
4546 * doc/Makefile: fixed install, added local_icons
4547 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4548 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4549 * src/ds390/gen.c (genRightShift): fixed bug #870788

4552 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4554 PIC16 port related changes:
4555 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4556 added variable stackPos,
4558 * gen.c: genCall, assignResultValue: added support for
4559 pushing/retrieving function parameters to/from stack,
4560 genFunction,genEndFunction: setup stack frame for the
4562 genAddrOf: will be changed according to bug 863624
4564 * added files genutils.c and genutils.h which contain gen*
4565 debugged and optimised functions extracted from gen.c
4567 * glue.c: added variable 'externs' which holds extern symbols,
4568 pic16emitRegularMap: is modified to properly handle relocatable
4569 symbols under the new scheme,
4570 pic16createInterruptVect: is modified
4571 pic16printPublics: is modified to emit 'global' assembler directives,
4572 added pic16_printExterns to print extern symbols,
4573 pic16glue: initializes stack/frame pointer in the beginning of
4574 the assembly output. Temporary hack, will be corrected later,
4575 because gplink yet does not support stack and SDCC does not
4576 yet support a type of crt0.o object to create the final binary.
4578 * Removed many lines that contain 8051 legacy code.
4579 * The code is finally placed under a 'code' directive.
4580 * Added port specific options.
4582 * _process_pragma: simplified since now we do not need *special*
4583 include file to define SFR registers. But a separate header
4584 will be needed. This will be developed later.
4585 * _pic16_parseOptions: added, parses port specific options:
4586 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4587 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4588 --preplace-udata-with=
4590 * _pic16_setDefaultOptions: modified to initialize section names,
4591 but hack is temporarly out of order since it needs improvement.
4592 * _pic16_genAssemblerPreamble: configuration words are emitted by
4593 their address instead of their name. This part is incomplete and
4594 supports only the 18Fxx2 devices. Other devices will emit an error
4595 during assembly since they do not contain the same set of config
4597 * _pic16_genIVT: is modified,
4599 * pcode.c: added definitions for some hardware registers that are needed
4601 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4602 All PCI entries are updated. Now LFSR is supported.
4603 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4604 * added pic16_newpCodeOpLit2 to support instructions with
4605 two literal arguments
4606 * pic16_pCode2str: corrected code that emits assembler instructions
4607 with two literal operands and those that have an access bit modifier
4608 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4609 this fixes a bug which caused some labels to be lost, when an
4610 assembler directive was added, i.e. banksel,
4611 * pic16_FixRegisterBanking: improved logic that causes the insertion
4613 * InlineFunction: functions that are called once, are not any more
4614 inlined. This can be a port option in the future,
4616 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4618 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4619 hold the corresponding uninitialized symbols,
4620 * pic16_allocProcessorRegister: registers have explicit marked the
4622 * pic16_allocInternalRegister: registers are explicit marked as
4624 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4625 processing list, so bit registers were lost,
4628 * ralloc.h: added field 'accessBank' and original symbol operand
4629 in register definition,
4630 * removed the field isMapped from register definition,
4632 ** Several functions have been removed from various sources:
4633 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4634 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4635 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4636 pic16_assignRelocatableRegisters
4638 ** others have been introduced:
4639 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4640 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4642 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4644 * support/scripts/inc2h.pl: changed definition of BIT_AT
4645 to emit 'sbit at' instead of 'bit at'. This was a request.
4647 PIC16 port related preliminary changes:
4648 * gen.c: prefixed function popRegFromString with
4649 pic16_ and all references to it corrected
4650 * pcode.c: all pic16_pc_* hardware registers prefixed
4651 with underscore (_),
4652 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4653 * ralloc.c: newReg(): when register is REG_SFR then
4654 set address to rIdx,
4655 pic16_allocProcessorRegister(): marks register wasUsed=0
4656 pic16_writeUsedRegs(): added a call to assign processor
4657 registers via pic16_assignFixedRegisters
4659 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4661 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4662 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4663 variables in unused register banks. Also the SSEG is placed
4664 wherever there is enough space for it, and IDATA can be anywhere
4665 in internal RAM. For now compile using -Wl-Y[stack_size].
4666 The mem file is different for this option as well, since it
4667 makes no sense of talking about DSEG lenght.
4669 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4671 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4672 in certain cases, e.g. when ROM assignment, patch provided
4673 from Albert den Haan.
4675 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4914 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4916 * src/SDCCast.c (decorateType): disabled a transformation I added in
4917 revision 1.188 (access to fields of a structure at an absolute address);
4918 it breaks with bitfields, extern declarations, and gcse analysis.
4919 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4920 could be assigned through a pointer, so don't complain.
4921 * src/SDCCast.c (astErrors),
4923 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
4925 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

4931 pre-processor macro, i.e. -DMCU=p18f452
4932 * src/pic16/ralloc.c: renamed packRegisters to pic16_packRegisters,
4933 and modified to handle 'cast' icode similarly to '=' icode

5676 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5677 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5678 fetching of the pointer
5679 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5680 copied from genNearPointerSet()
5681 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5682 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5683 If they pop r0/r1 they must be called in the opposite order than aopOp().
5684 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5685 (resp. --stack-auto), prepared for --xstack

5698 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5699 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5700 type for bits was changed. It resulted in bit variables becoming
5701 global, which is not permitted in PIC 14 assembly output.
5703 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5705 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5718 A few small changes that speed up the peephole optimizer.
5722 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5724 Try to make the peephole optimizer smarter by maintaining
5725 an association between the assembly source code and the
5726 iCodes that originated them. Put this information to use
5727 with a new peephole rule condition "notVolatile" so that
5728 the rules can be aggressive yet still safe.
5733 * src/mcs51/peeph.def
5735 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5739 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5740 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5741 if the left or right operand symbols have the accuse flag set.
5743 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5745 Changed the type of the result of the ! (NOT) operator to char;
5746 previously it returned the same type as the source. This allows
5747 us to eliminate all the genFloatNot functions (all of its target
5748 implementations were very buggy) since !float can use the same
5751 * src/SDCCicode.c (ast2iCode): ! returns char

5760 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5761 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5762 during interrupts. Ensure WSAVE is located at a shared bank address.
5763 2. Fixed page selection in some places
5764 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5765 the registers name strings.
5766 4. Fixed "signed / unsigned compare" compiler warnings.
5767 5. The PIC port manages its own allocation of the general purpose
5768 registers, but makes no attempt to reuse them. As a result when
5769 compiling it soon runs out of general purpose registers. Some
5770 additional code was added to the files pcode.c and device.c to walk
5771 through the function call tree and rename the registers so that they
5781 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5782 genPlus() & genMinus() when the result is the same as left or right

5788 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5790 Made bitfield a distinct type from bit so that bitfields
5791 convert as per ANSI C and bits retain their traditional
5792 boolean style behaviour. Implemented bitfield support in
5800 * src/ds390/gen.c: bit v bitfield split
5801 * src/z80/gen.c: New support for bitfields
5802 * support/regression/tests/bitfields.c: reenabled z80,
5805 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5807 Rules 246.x, 247.x relate to bitfields, the others speed up
5808 access to xdata mapped I/O devices.
5810 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5812 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5814 Cleaned up genPackBits and genUnpackBits and added two helper
5815 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5816 for literal assignments in genPackBits (thanks to Frieder for
5822 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5824 Fixed bug #748310 (pointer to function type mishandled when the
5825 function name is omitted). Also fixed a SIGSEGV when a function
5826 attribute (reentrant, etc) is used on a non-function or on a
5827 function but misplaced before the parameter list.
5829 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5831 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5832 * support/Util/SDCCerr.h,

5854 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5856 Made the constant following the "interrupt" keyword optional. If
5857 omitted, the function will not automatically be given an entry
5858 in the interrupt vector table (similar to #pragma NOIV, but
5859 less syntacticly kludgy). The interrupt number is also now
5860 range checked. Also fixed a bug in the high order bit example

6390 added if/endif conditional macros to remove options help
6391 messages from optionsTable when a port is not configured, added
6392 support for the PIc16 port in the ports table, when executing
6393 the compiler with no port specified on command line, a default
6394 port is selected with the new macro DEFAULT_PORT which is
6395 defined in port.h, in setDefaultOptions() linkOptions is removed
6396 from initialization assignment, since now it is a set,
6397 parseCmdLine uses setParseWithComma for linkOptions, in
6398 linkEdit() linkOptions are accessed with new function indexSet()
6399 which returns the i'th item of a set variable. See SDCCset.c, in
6400 linkEdit() when calling buildCmdLine(), added linkOptions as
6401 last argument. Now users can pass arguments to gplink via the
6402 -Wl option, main() uses pic16glue() to glue up pic16 programs

6416 gpasm complaining and test the linkage with gplink, _linkCmd and
6417 _asmCmd changed to be more gplink and gpasm friendly
6418 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6419 produced an error when parsed, peep rule 12 is added to utilize
6420 movff, but it is commented out since the pCode does not support
6421 yet a command with 2 address arguments
6423 2003-05-18 <johan AT balder>
6425 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7458 2003-01-06 <johan AT balder>
7460 * src/SDCCicode.c: fixed array add
7462 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7463 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7464 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7466 2003-01-04 <johan AT balder>
7468 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7470 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7471 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7473 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7474 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

7483 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7484 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7486 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7488 * in \sdcc\as\mcs51\ changed these files in order to create an
7489 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7490 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7491 following files to include the previous two files: aslink.dsp,
7492 Makefile.aslink, Makefile.bcc, and Makefile.in.
7494 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7495 .adb instead of .cdb
7497 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7499 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7500 value from option --iram-size.
7502 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7504 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7507 2002-09-18 <wiml AT hhhh.org>
7509 * SDCClrange.h: exposed setFromRange() and setToRange()
7510 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7511 packRegsForAccUse() (bug 542397)
7512 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7513 multiple times and emitting the fetch operations more than once
7514 added aopGetUsesAcc() function to allow binary operators to
7515 fetch their operands in the correct order; made genMinus() emit
7516 compact code for X = LITERAL - Y
7518 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7519 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7520 sprintf() in line 1267.
7522 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7523 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7526 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7527 Changes to aslink (All the changes are marked with 'JCF'):
7529 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7532 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7533 area BSEG. Also moves, if possible, the DATA area down into the internal
7534 ram so more space is available.
7536 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7539 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7540 not bytes. Function summary() which creates a memory usage summary
7541 file with extension .mem. Reports of overlaping stack and small stack
7542 size. If the space for the stack is less than 16 bytes aslink trows a
7545 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7546 the 8051. Option 'y' for memory summary output file.
7548 Changes to sdcc (All the changes are marked with 'JCF'):
7550 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7552 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7553 overlaying area for it (uses RegBankUsed[4]).
7555 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7556 bank zero as used by default. By default aslink locates the stack
7557 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7558 the creation of the .mem file. Delegates the allocation of data area
7559 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7560 the begining of the stack area to aslink.
7562 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7563 glue() in SDCCglue.c creates an area for it.
7565 2002-09-03 Borut Razem <borut.razem AT siol.net>
7566 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7567 sdcc/src/pic/glue.c:
7568 introduced atexit() handler for teporay files removal in case of
7569 errors, assertions, ...
7571 2002-08-29 Borut Razem <borut.razem AT siol.net>
7572 * sdcc/support/cpp2/auto-host_vc_in.h:
7573 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7574 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7575 Maybe there is a similar problem with BORLANDC? It should be checked!
7577 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7578 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7579 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7580 was not executed, and the compiler (cl) launched a warning:
7581 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7583 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7584 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7586 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7587 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7589 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7590 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7591 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7592 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7593 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7594 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7595 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7596 - added Release configuration in VS projects
7597 - review of compiler an linker options
7598 - VC .exe files are generated in bin_vc directory, not to interfere
7599 with binaries generated from other projects (cygwin, mingw, bcc ...)
7601 * sdcc/src/yacc.dsp: added
7603 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7604 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7605 and insert the version number definitions from .version
7607 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7609 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7610 added - genarate auto-host.h using auto-host_vc_in.h as template
7613 removed from CVS, generated automatically
7615 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7616 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7618 2002-08-11 Borut Razem <borut.razem AT siol.net>
7619 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7621 2002-08-10 Borut Razem <borut.razem AT siol.net>
7622 * src/SDCCmain.c (main):
7623 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7624 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7625 The consequence was that some temporary files were not removed.
7628 unification of code in functions tempfilename() and tempfile():
7629 function tempnam() is defined in Visual Studio 6.0 and .NET
7631 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7633 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7634 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7635 - removed compiler command line option /WX: Treats all warnings as errors
7636 - update a list of source files, included into the project
7638 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7639 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7640 changed project type to Generic Project so that can be correcly converted to VS.NET project
7642 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7644 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7646 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7648 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7649 added return 0 statements after assert() to make compiler happy
7651 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7652 added newline in the def file to keep MSC compiler satisfied
7654 * sdcc/src/z80/gen.c:
7655 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7656 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7657 - solved MSC error in function aopDump()
7659 * sdcc_vc.h: define PREFIX as "\\sdcc"
7661 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7662 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7665 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7666 - Rewrote the register banking algorithm.
7667 - Added pCode live-range analysis to registers (for now, only non-used and
7668 singly-used registers optimized away)
7670 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7672 * 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.

7697 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7699 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7701 2002-03-28 Johan Knol <johan AT balder>
7703 * src/SDCCval.c: fixed bug #532436
7705 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7707 Added "char *Processor" field to the port structure.
7710 Added -p option. Allows port dependent processor to be specified.
7713 Initialized the new field char *Processor field to NULL in all ports
7716 Compiler generated registers for interrupt context saving
7717 were not getting allocated.
7719 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7722 Fixed left shift. Will promote the left side of a left shift
7723 if a) left shifting more than size of operand or b) when assigned
7724 to something size > size of left side
7726 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7728 tons of changes. Register allocation has been
7729 rewritten. Added customization for the various PICs. Flow
7730 analysis is restructured. ...
7736 Added. device.c is a PIC port hack to accomodate variations
7739 2002-03-13 Michael Hope <michaelh AT vroom>
7741 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7743 2002-03-04 johanknol <johanknol AT manik>
7745 * /src/SDCCval.c: fixed
7747 const unsigned char arr[][2] = { { 0, 1 } };
7748 t18.c:1: error: Initializer element is not constant
7750 2002-03-04 bela <bela AT manik>
7752 * /device/include/mcs51reg.h:
7753 ds89c420 register definition update
7755 2002-03-03 <johan AT FRIJA>

7834 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7836 * sdcc/src/SDCCloop.c:
7837 Previous fix was not good. basic blocks that have "break" or "return" are
7838 not really partof a loop , but live ranges used in these blocks should
7839 be live thru the entire loop, so set partOfLoop but don't add them to
7842 2002-02-21 <johan AT FRIJA>
7844 * src/SDCCcse.c: fixed bug #514308
7846 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7849 Fixed BUG #519583. If a conditional block ended in a return/break
7850 statement inside a loop, it was not being considered part of the loop.
7852 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7854 2002-02-10 Karl Bongers <karl AT turbobit.com>
7857 Fixed up SDCDB debugger somewhat. Updated debugger/README
7858 with lots of comments and notes.
7860 * device/examples/test2.c:
7861 Fix bug, "red" variable not being initialized(compiler complained).
7863 * device/examples/Makefile, examples/test3.c:
7864 Add Makefile in device/examples folder, compiles test3.c
7865 for use as a multiple module SDCDB test case.
7867 * sim/ucsim/cmd.src/cmdset.cc:
7868 Took out debug printfs in ucsim "next" command.
7871 Karl and Johan start ucsim XA support. Most dissassembly working,
7872 about 75% emulation done(plenty of work remaining).
7874 * sim/ucsim/z80.src:
7875 Add Z80 support to ucsim, add test-ucz80 regression test,
7876 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
7877 Notice z80 compiler fails on examples/test3.c/crc code.
7879 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
7881 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
7882 Added support for --parms-in-bank1
7884 * src/ds390/peeph.def:
7885 added a few more peephole optimzations
7888 1) added __builtin_inp & __builtin_outp used to read in data of given length
7889 from a memory mapped port
