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

1154 Adding support for replacing ljmps with sjmps in jumptables
1155 generated for switch statements. For now you need to set the
1156 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1157 Now 4 algorithms for mcs51 jumptable generation are used:
1158 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1159 addresses loaded pc-relative for up to 112 cases and stack-pushing
1160 target addresses loaded with offset from dptr for up to 256 cases.

1190 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1192 * added libc directory. The current version of LibC contains string
1193 functions, ctype functions and macros and some functions of the
1194 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1195 be extensively tested in the future. Standard disclaimer here.
1196 Library is not automatically build yet. But one can build it by

1208 * (pic16_storeForReturn): optimized return of 0,
1209 * (genCmp): experimental code for new genCmp which uses PIC18's
1210 special compare&skip instructions. Initial tests fail some times
1211 with variables grater than 1 byte in size, so new code is disabled,
1212 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1214 * (genCast): began a fix to optimize the casting of a bit to another
1215 bit, now assigning a bitfield to another bitfield will fail, sorry,

1224 and 1 for banking instruction,
1225 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1226 caused stop processing pCodes after a inline assembly block,
1227 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1229 registers when it shouldn't,
1230 * src/pic16/ralloc.c (allocReg): add preliminary support for
1231 supporting a limited set of temporary registers,
1233 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1239 (genFunction): optimize RECEIVE iCodes in reentrant functions
1241 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4241 loaded with the linker search paths (-L arguments) and the libraries
4242 to be linked with the current source (-l arguments). Changes
4243 currently will affect only the pic16 port.
4244 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4245 include path the port specific paths and port specific libraries,
4246 * gplink command now contains the $3 argument,
4247 * src/pic16/device.h,
4248 * src/pic16/device.c,: structure PIC_device is made public and
4249 renamed to PIC16_device, the same for variable Pics which is renamed

4264 Documenting changes from previous commits.
4265 * configure.in (version 1.56),
4266 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4267 when generating output files to configure the pic16 library,
4268 but now I've commented it out, since gputils aren't installed in the
4269 SF compile farm, so library won't compile
4271 * device/lib/Makefile.in (version 1.56): initially I've added in
4272 target 'all' the prerequestive 'model-pic16' so it compiled the
4273 pic16 library, but now I've commented it out for the same reasons
4275 * added targets 'model-pic16' and 'objects-pic16' to compile the
4277 * added target 'port-specific-objects-pic16' to handle the
4278 generated libraries and copy them into the build/ directory
4279 * added target 'clean-intermediate-pic16' to clean intermediate
4280 files into pic16 directory
4281 * in target 'installdirs' added line to create directory pic16 in

4303 option so that it actually works. Made it specific to the z80, since
4304 the gbz80 doesn't have these kinds of I/O ports.
4306 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4308 * device/include/z180.h,

4477 * src/z80/main.c: changed appropriately to configure
4478 needLinkerScript flag
4480 * src/pic16/gen.c (genAddrOf): fixed bug #863624
4481 * src/pic/glue.c: added variable udata_section_name to

4492 arguments via -W option
4493 * src/pic16/main.c: added $l in _asmCmd, changed extension for
4494 object file from '.rel' to '.o' in port->linker structure,
4495 changed size of fptr from 2 to 3 in port structure
4497 2004-01-07 Borut Razem <borut.razem AT siol.net>
4499 * support/scripts/sdcc.nsi: update PATH
4500 * support/scripts/sdcc.ico: craeted

4525 * support/valdiag/tests/overflow.c: added
4526 * src/SDCCast.c (decorateType),
4527 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
4528 LEFT_OP (left shift)
4530 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4532 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4533 (default behaviour).
4535 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4537 A python script to validate compiler diagnostic messages. It can be
4538 used to verify that sdcc complains about bad c source code and
4539 gives a good location of the error.
4540 * support/valdiag/Makefile,
4541 * support/valdiag/valdiag.py,
4542 * support/valdiag/tests/*
4544 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4557 * src/common.h: added ifndef/define/endif macros
4558 around the header file.
4559 Bug reported from Jesus Calvino-Fraga
4561 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4563 * sdcc.spec: updated
4564 * device/include/Makefile.in: don't install CVS directories
4565 * device/lib/Makefile.in: added removal of CVS directories after install
4566 * doc/Makefile: fixed install, added local_icons
4567 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4568 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4569 * src/ds390/gen.c (genRightShift): fixed bug #870788
4570 * src/SDCCast.c (decorateType): fixed bug #870781
4572 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4574 PIC16 port related changes:
4575 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4576 added variable stackPos,
4578 * gen.c: genCall, assignResultValue: added support for
4579 pushing/retrieving function parameters to/from stack,
4580 genFunction,genEndFunction: setup stack frame for the
4582 genAddrOf: will be changed according to bug 863624
4584 * added files genutils.c and genutils.h which contain gen*
4585 debugged and optimised functions extracted from gen.c
4587 * glue.c: added variable 'externs' which holds extern symbols,
4588 pic16emitRegularMap: is modified to properly handle relocatable
4589 symbols under the new scheme,
4590 pic16createInterruptVect: is modified
4591 pic16printPublics: is modified to emit 'global' assembler directives,
4592 added pic16_printExterns to print extern symbols,
4593 pic16glue: initializes stack/frame pointer in the beginning of
4594 the assembly output. Temporary hack, will be corrected later,
4595 because gplink yet does not support stack and SDCC does not
4596 yet support a type of crt0.o object to create the final binary.
4598 * Removed many lines that contain 8051 legacy code.
4599 * The code is finally placed under a 'code' directive.
4600 * Added port specific options.
4602 * _process_pragma: simplified since now we do not need *special*
4603 include file to define SFR registers. But a separate header
4604 will be needed. This will be developed later.
4605 * _pic16_parseOptions: added, parses port specific options:
4606 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4607 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4608 --preplace-udata-with=
4610 * _pic16_setDefaultOptions: modified to initialize section names,
4611 but hack is temporarly out of order since it needs improvement.
4612 * _pic16_genAssemblerPreamble: configuration words are emitted by
4613 their address instead of their name. This part is incomplete and
4614 supports only the 18Fxx2 devices. Other devices will emit an error
4615 during assembly since they do not contain the same set of config
4617 * _pic16_genIVT: is modified,
4619 * pcode.c: added definitions for some hardware registers that are needed
4621 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4622 All PCI entries are updated. Now LFSR is supported.
4623 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4624 * added pic16_newpCodeOpLit2 to support instructions with
4625 two literal arguments
4626 * pic16_pCode2str: corrected code that emits assembler instructions
4627 with two literal operands and those that have an access bit modifier
4628 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4629 this fixes a bug which caused some labels to be lost, when an
4630 assembler directive was added, i.e. banksel,
4631 * pic16_FixRegisterBanking: improved logic that causes the insertion
4633 * InlineFunction: functions that are called once, are not any more
4634 inlined. This can be a port option in the future,
4636 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4638 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4639 hold the corresponding uninitialized symbols,
4640 * pic16_allocProcessorRegister: registers have explicit marked the
4642 * pic16_allocInternalRegister: registers are explicit marked as
4644 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4645 processing list, so bit registers were lost,
4648 * ralloc.h: added field 'accessBank' and original symbol operand
4649 in register definition,
4650 * removed the field isMapped from register definition,
4652 ** Several functions have been removed from various sources:
4653 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4654 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4655 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4656 pic16_assignRelocatableRegisters
4658 ** others have been introduced:
4659 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4660 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4662 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4664 * support/scripts/inc2h.pl: changed definition of BIT_AT
4665 to emit 'sbit at' instead of 'bit at'. This was a request.
4667 PIC16 port related preliminary changes:
4668 * gen.c: prefixed function popRegFromString with
4669 pic16_ and all references to it corrected
4670 * pcode.c: all pic16_pc_* hardware registers prefixed
4671 with underscore (_),
4672 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4673 * ralloc.c: newReg(): when register is REG_SFR then
4674 set address to rIdx,
4675 pic16_allocProcessorRegister(): marks register wasUsed=0
4676 pic16_writeUsedRegs(): added a call to assign processor
4677 registers via pic16_assignFixedRegisters
4679 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4681 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4682 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4683 variables in unused register banks. Also the SSEG is placed
4684 wherever there is enough space for it, and IDATA can be anywhere
4685 in internal RAM. For now compile using -Wl-Y[stack_size].
4686 The mem file is different for this option as well, since it
4687 makes no sense of talking about DSEG lenght.
4689 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4691 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4692 in certain cases, e.g. when ROM assignment, patch provided
4693 from Albert den Haan.

4934 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4936 * src/SDCCast.c (decorateType): disabled a transformation I added in
4937 revision 1.188 (access to fields of a structure at an absolute address);
4938 it breaks with bitfields, extern declarations, and gcse analysis.
4939 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4940 could be assigned through a pointer, so don't complain.

5581 support for standard C idiom of memory mapped variables; for
5582 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5583 to xdata int at 0x1234 tempvar = 1.

5697 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5698 fetching of the pointer
5699 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5700 copied from genNearPointerSet()
5701 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5702 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5703 If they pop r0/r1 they must be called in the opposite order than aopOp().

5718 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5719 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5720 type for bits was changed. It resulted in bit variables becoming
5721 global, which is not permitted in PIC 14 assembly output.
5723 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5738 A few small changes that speed up the peephole optimizer.
5742 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5744 Try to make the peephole optimizer smarter by maintaining
5745 an association between the assembly source code and the
5746 iCodes that originated them. Put this information to use
5747 with a new peephole rule condition "notVolatile" so that
5748 the rules can be aggressive yet still safe.
5753 * src/mcs51/peeph.def
5755 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5759 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5760 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5761 if the left or right operand symbols have the accuse flag set.
5763 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5765 Changed the type of the result of the ! (NOT) operator to char;
5766 previously it returned the same type as the source. This allows
5767 us to eliminate all the genFloatNot functions (all of its target
5768 implementations were very buggy) since !float can use the same
5771 * src/SDCCicode.c (ast2iCode): ! returns char

5780 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5781 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5782 during interrupts. Ensure WSAVE is located at a shared bank address.
5783 2. Fixed page selection in some places
5784 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5785 the registers name strings.
5786 4. Fixed "signed / unsigned compare" compiler warnings.
5787 5. The PIC port manages its own allocation of the general purpose
5788 registers, but makes no attempt to reuse them. As a result when
5789 compiling it soon runs out of general purpose registers. Some
5790 additional code was added to the files pcode.c and device.c to walk
5791 through the function call tree and rename the registers so that they
5801 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5808 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5810 Made bitfield a distinct type from bit so that bitfields
5811 convert as per ANSI C and bits retain their traditional
5812 boolean style behaviour. Implemented bitfield support in
5820 * src/ds390/gen.c: bit v bitfield split
5821 * src/z80/gen.c: New support for bitfields
5822 * support/regression/tests/bitfields.c: reenabled z80,
5825 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5827 Rules 246.x, 247.x relate to bitfields, the others speed up
5828 access to xdata mapped I/O devices.
5830 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5832 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5834 Cleaned up genPackBits and genUnpackBits and added two helper
5835 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5836 for literal assignments in genPackBits (thanks to Frieder for
5842 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5844 Fixed bug #748310 (pointer to function type mishandled when the
5845 function name is omitted). Also fixed a SIGSEGV when a function
5846 attribute (reentrant, etc) is used on a non-function or on a
5847 function but misplaced before the parameter list.
5849 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5851 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5852 * support/Util/SDCCerr.h,

5874 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5876 Made the constant following the "interrupt" keyword optional. If
5877 omitted, the function will not automatically be given an entry
5878 in the interrupt vector table (similar to #pragma NOIV, but
5879 less syntacticly kludgy). The interrupt number is also now
5880 range checked. Also fixed a bug in the high order bit example

5946 constants are unsigned; added recognition of "u" flag for unsigned
5947 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5948 * src/SDCCval.c (valDiv, valMod): fixed signdness

6410 added if/endif conditional macros to remove options help
6411 messages from optionsTable when a port is not configured, added
6412 support for the PIc16 port in the ports table, when executing
6413 the compiler with no port specified on command line, a default
6414 port is selected with the new macro DEFAULT_PORT which is
6415 defined in port.h, in setDefaultOptions() linkOptions is removed
6416 from initialization assignment, since now it is a set,
6417 parseCmdLine uses setParseWithComma for linkOptions, in
6418 linkEdit() linkOptions are accessed with new function indexSet()
6419 which returns the i'th item of a set variable. See SDCCset.c, in
6420 linkEdit() when calling buildCmdLine(), added linkOptions as
6421 last argument. Now users can pass arguments to gplink via the
6422 -Wl option, main() uses pic16glue() to glue up pic16 programs

6436 gpasm complaining and test the linkage with gplink, _linkCmd and
6437 _asmCmd changed to be more gplink and gpasm friendly
6438 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6439 produced an error when parsed, peep rule 12 is added to utilize
6440 movff, but it is commented out since the pCode does not support
6441 yet a command with 2 address arguments
6443 2003-05-18 <johan AT balder>
6445 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7463 2003-01-07 <johan AT balder>
7465 * src/SDCCast.c (decorateType): fixed bug #600035
7467 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>

7478 2003-01-06 <johan AT balder>
7480 * src/SDCCicode.c: fixed array add
7482 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7483 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7484 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7486 2003-01-04 <johan AT balder>
7488 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7490 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7491 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7493 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7494 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

7500 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7501 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7503 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7504 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7506 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7508 * in \sdcc\as\mcs51\ changed these files in order to create an
7509 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7510 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7511 following files to include the previous two files: aslink.dsp,
7512 Makefile.aslink, Makefile.bcc, and Makefile.in.
7514 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7515 .adb instead of .cdb
7517 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7519 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7520 value from option --iram-size.
7522 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7524 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7527 2002-09-18 <wiml AT hhhh.org>
7529 * SDCClrange.h: exposed setFromRange() and setToRange()
7530 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7531 packRegsForAccUse() (bug 542397)
7532 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7533 multiple times and emitting the fetch operations more than once
7534 added aopGetUsesAcc() function to allow binary operators to
7535 fetch their operands in the correct order; made genMinus() emit
7536 compact code for X = LITERAL - Y
7538 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7539 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7540 sprintf() in line 1267.
7542 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7543 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7546 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7547 Changes to aslink (All the changes are marked with 'JCF'):
7549 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7552 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7553 area BSEG. Also moves, if possible, the DATA area down into the internal
7554 ram so more space is available.
7556 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7559 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7560 not bytes. Function summary() which creates a memory usage summary
7561 file with extension .mem. Reports of overlaping stack and small stack
7562 size. If the space for the stack is less than 16 bytes aslink trows a
7565 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7566 the 8051. Option 'y' for memory summary output file.
7568 Changes to sdcc (All the changes are marked with 'JCF'):
7570 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7572 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7573 overlaying area for it (uses RegBankUsed[4]).
7575 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7576 bank zero as used by default. By default aslink locates the stack
7577 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7578 the creation of the .mem file. Delegates the allocation of data area
7579 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7580 the begining of the stack area to aslink.
7582 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7583 glue() in SDCCglue.c creates an area for it.
7585 2002-09-03 Borut Razem <borut.razem AT siol.net>
7586 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7587 sdcc/src/pic/glue.c:
7588 introduced atexit() handler for teporay files removal in case of
7589 errors, assertions, ...
7591 2002-08-29 Borut Razem <borut.razem AT siol.net>
7592 * sdcc/support/cpp2/auto-host_vc_in.h:
7593 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7594 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7595 Maybe there is a similar problem with BORLANDC? It should be checked!
7597 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7598 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7599 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7600 was not executed, and the compiler (cl) launched a warning:
7601 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7603 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7604 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7606 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7607 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7609 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7610 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7611 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7612 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7613 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7614 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7615 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7616 - added Release configuration in VS projects
7617 - review of compiler an linker options
7618 - VC .exe files are generated in bin_vc directory, not to interfere
7619 with binaries generated from other projects (cygwin, mingw, bcc ...)
7621 * sdcc/src/yacc.dsp: added
7623 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7624 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7625 and insert the version number definitions from .version
7627 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7629 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7630 added - genarate auto-host.h using auto-host_vc_in.h as template
7633 removed from CVS, generated automatically
7635 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7636 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7638 2002-08-11 Borut Razem <borut.razem AT siol.net>
7639 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7641 2002-08-10 Borut Razem <borut.razem AT siol.net>
7642 * src/SDCCmain.c (main):
7643 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7644 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7645 The consequence was that some temporary files were not removed.
7648 unification of code in functions tempfilename() and tempfile():
7649 function tempnam() is defined in Visual Studio 6.0 and .NET
7651 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7653 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7654 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7655 - removed compiler command line option /WX: Treats all warnings as errors
7656 - update a list of source files, included into the project
7658 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7659 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7660 changed project type to Generic Project so that can be correcly converted to VS.NET project
7662 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7664 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7666 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7668 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7669 added return 0 statements after assert() to make compiler happy
7671 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7672 added newline in the def file to keep MSC compiler satisfied
7674 * sdcc/src/z80/gen.c:
7675 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7676 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7677 - solved MSC error in function aopDump()
7679 * sdcc_vc.h: define PREFIX as "\\sdcc"
7681 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7682 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7685 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7686 - Rewrote the register banking algorithm.
7687 - Added pCode live-range analysis to registers (for now, only non-used and
7688 singly-used registers optimized away)
7690 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7692 * 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.

7719 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7721 2002-03-28 Johan Knol <johan AT balder>
7723 * src/SDCCval.c: fixed bug #532436
7725 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7727 Added "char *Processor" field to the port structure.
7730 Added -p option. Allows port dependent processor to be specified.
7733 Initialized the new field char *Processor field to NULL in all ports
7736 Compiler generated registers for interrupt context saving
7737 were not getting allocated.
7739 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7742 Fixed left shift. Will promote the left side of a left shift
7743 if a) left shifting more than size of operand or b) when assigned
7744 to something size > size of left side
7746 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7748 tons of changes. Register allocation has been
7749 rewritten. Added customization for the various PICs. Flow
7750 analysis is restructured. ...
7756 Added. device.c is a PIC port hack to accomodate variations
7759 2002-03-13 Michael Hope <michaelh AT vroom>
7761 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7763 2002-03-04 johanknol <johanknol AT manik>
7765 * /src/SDCCval.c: fixed
7767 const unsigned char arr[][2] = { { 0, 1 } };
7768 t18.c:1: error: Initializer element is not constant
7770 2002-03-04 bela <bela AT manik>
7772 * /device/include/mcs51reg.h:
7773 ds89c420 register definition update

7854 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7856 * sdcc/src/SDCCloop.c:
7857 Previous fix was not good. basic blocks that have "break" or "return" are
7858 not really partof a loop , but live ranges used in these blocks should
7859 be live thru the entire loop, so set partOfLoop but don't add them to
7862 2002-02-21 <johan AT FRIJA>
7864 * src/SDCCcse.c: fixed bug #514308
7866 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7869 Fixed BUG #519583. If a conditional block ended in a return/break
7870 statement inside a loop, it was not being considered part of the loop.
7872 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7874 2002-02-10 Karl Bongers <karl AT turbobit.com>
7877 Fixed up SDCDB debugger somewhat. Updated debugger/README
7878 with lots of comments and notes.
7880 * device/examples/test2.c:
7881 Fix bug, "red" variable not being initialized(compiler complained).
