450 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
451 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
452 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
453 immedDom() returning wrong block; probably fixes bug #1160833)
455 2005-03-20 Borut Razem <borut.razem AT siol.net>
457 * support/scripts/inc2h.pl: WIN32 port
459 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
461 * device/lib/makefile.in: added abs.c and labs.c
463 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
465 * device/include/stdint.h: added
466 * device/lib/abs.c: added
467 * device/lib/labs.c: added
468 * device/include/stdlib.h: added abs() and labs() prototypes
469 * device/lib/libsdcc.lib: added abs and labs
470 * device/include/float.h,
471 * device/lib/_fsmul.c,
472 * device/lib/printf_fast.c,
473 * device/lib/printf_tiny.c: updated comments
475 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
477 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
480 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
482 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
483 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
485 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
487 * device/lib/printf_large.c: removed inline assembly for portability and
488 readability. Use printf_fast if speed or size are more important.
489 * src/pic16/gen.c: removed conditions around use of DEBUGpc
490 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
492 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
494 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
495 prevent compiler warning
497 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
499 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
500 moved to level 0 and declared as static. Also they are explicit
501 placed in access bank. This was necessery because some times they
502 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
503 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
504 optimizations. Currently only compare to unsigned char is implemented,
505 * src/pic16/gen.c: added fReturnIdx array,
506 * (struct resolvedIfx) is moved to gen.h and made public,
507 * (struct _G): added sregsAlloc and sregsAllocSet fields,
508 * (aopForSym): added an optimization to directly store in stack of
509 the operand of a SEND iCode,
510 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
511 but as registers instead (AOP_REG) using the fReturnIdx array,
512 * (pic16_freeAsmop): remove the freed register from the
514 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
516 * (pic16_popGetTempRegCond): changed function prototype, now
517 function takes also a bitVector argument v which holds the current
518 set of registers that are allocated for stack access by aopForSym,
519 registers allocated in aopForSym for accessing stack symbols are not
520 any more part of the functions usedRegs field,
521 * (genCall): some times aopOp is called for a stack variable to be
522 send, aopForSym might perform the push, if this is true make sure
523 that genCall doesn't push the variable twice by testing _G.resDirect,
524 * (genFunction): changed testing for unspecified interrupt number
525 from 256 to INTNO_UNSPEC,
526 * modified selection scheme of frame pointer generation. Previously
527 if function did use local registers a frame pointer was generated,
528 now a frame pointer is generated only if function has arguments
529 (that need PLUSW2 register access), or has stack arguments, or the
530 compiler is not instructed to omit the frame pointer,
531 * (genEndFunction): before restoring local registers that were saved
532 in the function preamble, also restore the registers that *might*
533 have been allocated for stack access,
534 * (genRet): removed some old comments,
535 * (genCmp, the active (RN's) version): added a call to the
536 pic16_genCmp_special function to perform the compare with a more
537 robust and optimized way,
538 * (genInline): a feature has been added in inline code generation,
539 which allows a wildcard variable substitution when writing inline
540 assembly. Code is incomplete and experimental therefore undocumented,
541 * (genCast): changed order of aopOp for result and right to allow
542 aopForSym to directly load the result if possible,
543 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
544 perform an optimized compare on some selected special occasions,
545 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
546 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
547 generate an IVT any more,
548 * src/pic16/main.c (pic16_optionsTable): added command line option
550 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
551 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
553 * src/pic16/NOTES: Raphael Neider added in list of active developers
554 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
555 jumptable_end to prevent bug #,
556 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
557 inCond and outCond fields,
558 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
559 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
560 turn off register spilling,
561 * (packRegsForOneUse): synced with other ports' versions although it
562 is not used currently,
563 * (pic16_packRegisters): added an optimization while reading
564 structure bitfields, some registers may be saved (malloc code is
565 decreased by 80 bytes)
567 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
569 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
570 left is a bitfield, if yes, then don't optimize assignment. Perhaps
571 this can be optimized more?
573 2005-03-10 Raphael Neider <rneider AT web.de>
575 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
576 genNearPointerGet): (hopefully) fixed access to bitfields via
577 pointers (p->bitN = x; and x = p->bitN; failed)

623 to keep the correct label reference count when adding/removing references
624 to labels. A peephole file using this is appended to patch #1144962.

862 operands (genAddLit expects the iCode's operands to swapped as
863 well), fixed leftover bytes (crashed for short left operands)

1211 Adding support for replacing ljmps with sjmps in jumptables
1212 generated for switch statements. For now you need to set the
1213 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1214 Now 4 algorithms for mcs51 jumptable generation are used:
1215 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1216 addresses loaded pc-relative for up to 112 cases and stack-pushing
1217 target addresses loaded with offset from dptr for up to 256 cases.

1247 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1249 * added libc directory. The current version of LibC contains string
1250 functions, ctype functions and macros and some functions of the
1251 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1252 be extensively tested in the future. Standard disclaimer here.
1253 Library is not automatically build yet. But one can build it by

1265 * (pic16_storeForReturn): optimized return of 0,
1266 * (genCmp): experimental code for new genCmp which uses PIC18's
1267 special compare&skip instructions. Initial tests fail some times
1268 with variables grater than 1 byte in size, so new code is disabled,
1269 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1271 * (genCast): began a fix to optimize the casting of a bit to another
1272 bit, now assigning a bitfield to another bitfield will fail, sorry,

1281 and 1 for banking instruction,
1282 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1283 caused stop processing pCodes after a inline assembly block,
1284 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

1286 registers when it shouldn't,
1287 * src/pic16/ralloc.c (allocReg): add preliminary support for
1288 supporting a limited set of temporary registers,
1290 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1292 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

1296 (genFunction): optimize RECEIVE iCodes in reentrant functions
1298 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4295 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4297 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4298 loaded with the linker search paths (-L arguments) and the libraries
4299 to be linked with the current source (-l arguments). Changes
4300 currently will affect only the pic16 port.
4301 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4302 include path the port specific paths and port specific libraries,
4303 * gplink command now contains the $3 argument,
4304 * src/pic16/device.h,
4305 * src/pic16/device.c,: structure PIC_device is made public and
4306 renamed to PIC16_device, the same for variable Pics which is renamed

4321 Documenting changes from previous commits.
4322 * configure.in (version 1.56),
4323 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4324 when generating output files to configure the pic16 library,
4325 but now I've commented it out, since gputils aren't installed in the
4326 SF compile farm, so library won't compile
4328 * device/lib/Makefile.in (version 1.56): initially I've added in
4329 target 'all' the prerequestive 'model-pic16' so it compiled the
4330 pic16 library, but now I've commented it out for the same reasons
4332 * added targets 'model-pic16' and 'objects-pic16' to compile the
4334 * added target 'port-specific-objects-pic16' to handle the
4335 generated libraries and copy them into the build/ directory
4336 * added target 'clean-intermediate-pic16' to clean intermediate
4337 files into pic16 directory
4338 * in target 'installdirs' added line to create directory pic16 in
4339 the installation path

4342 added lines to copy all header files to installation path,
4343 * in target 'installdirs' added line create directory for pic16
4344 headers in the installation path

4359 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4360 option so that it actually works. Made it specific to the z80, since
4361 the gbz80 doesn't have these kinds of I/O ports.
4363 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4365 * device/include/z180.h,

4389 via literal number. The symbol is placed in the corresponding
4390 position of the data ram
4391 * (pic16_dump_section): relocatable and absolute uninitialized
4392 data are now emitted in sorted order to reduce section naming,
4393 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4394 weren't marked as being in the access bank,
4396 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4398 Added portion of GNU PIC Library under the directory
4399 device/include/pic16 and device/lib/pic16. These files
4400 contain the declarations of SFRs for the PIC18Fxx2 devices.
4401 The directory is initialized via configure from toplevel.

4472 UPPER for immediate operands,
4473 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4475 * src/pic16/peeph.def: all peepholes with movff are commented out,
4476 because there is a problem in the pcode peep optimizer,
4477 * src/pic16/ralloc.c: the register allocator can now reuse local
4478 function symbols for another function. This saves register usage.

4587 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4589 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4590 (default behaviour).
4592 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4594 A python script to validate compiler diagnostic messages. It can be
4595 used to verify that sdcc complains about bad c source code and
4596 gives a good location of the error.
4597 * support/valdiag/Makefile,
4598 * support/valdiag/valdiag.py,

4618 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4620 * sdcc.spec: updated
4621 * device/include/Makefile.in: don't install CVS directories
4622 * device/lib/Makefile.in: added removal of CVS directories after install
4623 * doc/Makefile: fixed install, added local_icons
4624 * sim/ucsim/gui.src/Makefile.in: fixed an old typo

4629 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4631 PIC16 port related changes:
4632 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4633 added variable stackPos,
4635 * gen.c: genCall, assignResultValue: added support for
4636 pushing/retrieving function parameters to/from stack,
4637 genFunction,genEndFunction: setup stack frame for the
4639 genAddrOf: will be changed according to bug 863624
4641 * added files genutils.c and genutils.h which contain gen*
4642 debugged and optimised functions extracted from gen.c
4644 * glue.c: added variable 'externs' which holds extern symbols,
4645 pic16emitRegularMap: is modified to properly handle relocatable
4646 symbols under the new scheme,
4647 pic16createInterruptVect: is modified
4648 pic16printPublics: is modified to emit 'global' assembler directives,
4649 added pic16_printExterns to print extern symbols,
4650 pic16glue: initializes stack/frame pointer in the beginning of
4651 the assembly output. Temporary hack, will be corrected later,
4652 because gplink yet does not support stack and SDCC does not
4653 yet support a type of crt0.o object to create the final binary.
4655 * Removed many lines that contain 8051 legacy code.
4656 * The code is finally placed under a 'code' directive.
4657 * Added port specific options.
4659 * _process_pragma: simplified since now we do not need *special*
4660 include file to define SFR registers. But a separate header
4661 will be needed. This will be developed later.
4662 * _pic16_parseOptions: added, parses port specific options:
4663 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4664 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4665 --preplace-udata-with=
4667 * _pic16_setDefaultOptions: modified to initialize section names,
4668 but hack is temporarly out of order since it needs improvement.
4669 * _pic16_genAssemblerPreamble: configuration words are emitted by
4670 their address instead of their name. This part is incomplete and
4671 supports only the 18Fxx2 devices. Other devices will emit an error
4672 during assembly since they do not contain the same set of config
4674 * _pic16_genIVT: is modified,
4676 * pcode.c: added definitions for some hardware registers that are needed
4678 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4679 All PCI entries are updated. Now LFSR is supported.
4680 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4681 * added pic16_newpCodeOpLit2 to support instructions with
4682 two literal arguments
4683 * pic16_pCode2str: corrected code that emits assembler instructions
4684 with two literal operands and those that have an access bit modifier
4685 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4686 this fixes a bug which caused some labels to be lost, when an
4687 assembler directive was added, i.e. banksel,
4688 * pic16_FixRegisterBanking: improved logic that causes the insertion
4690 * InlineFunction: functions that are called once, are not any more
4691 inlined. This can be a port option in the future,
4693 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4695 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4696 hold the corresponding uninitialized symbols,
4697 * pic16_allocProcessorRegister: registers have explicit marked the
4699 * pic16_allocInternalRegister: registers are explicit marked as
4701 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4702 processing list, so bit registers were lost,
4705 * ralloc.h: added field 'accessBank' and original symbol operand
4706 in register definition,
4707 * removed the field isMapped from register definition,
4709 ** Several functions have been removed from various sources:
4710 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4711 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4712 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4713 pic16_assignRelocatableRegisters
4715 ** others have been introduced:
4716 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4717 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4719 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4721 * support/scripts/inc2h.pl: changed definition of BIT_AT
4722 to emit 'sbit at' instead of 'bit at'. This was a request.
4724 PIC16 port related preliminary changes:
4725 * gen.c: prefixed function popRegFromString with
4726 pic16_ and all references to it corrected
4727 * pcode.c: all pic16_pc_* hardware registers prefixed
4728 with underscore (_),
4729 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4730 * ralloc.c: newReg(): when register is REG_SFR then
4731 set address to rIdx,
4732 pic16_allocProcessorRegister(): marks register wasUsed=0
4733 pic16_writeUsedRegs(): added a call to assign processor
4734 registers via pic16_assignFixedRegisters
4736 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4738 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4739 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4740 variables in unused register banks. Also the SSEG is placed
4741 wherever there is enough space for it, and IDATA can be anywhere
4742 in internal RAM. For now compile using -Wl-Y[stack_size].
4743 The mem file is different for this option as well, since it
4744 makes no sense of talking about DSEG lenght.
4746 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4748 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4749 in certain cases, e.g. when ROM assignment, patch provided
4750 from Albert den Haan.
4752 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4895 * src/mcs51/peephole.def,
4896 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

5638 support for standard C idiom of memory mapped variables; for
5639 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5640 to xdata int at 0x1234 tempvar = 1.
5641 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5642 provided by Akiya ISHIDA

5753 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5754 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5755 fetching of the pointer
5756 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5757 copied from genNearPointerSet()
5758 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5759 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5760 If they pop r0/r1 they must be called in the opposite order than aopOp().

5771 these ports have their own __sdcc_external_start()
5773 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5775 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5776 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5777 type for bits was changed. It resulted in bit variables becoming
5778 global, which is not permitted in PIC 14 assembly output.
5780 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5795 A few small changes that speed up the peephole optimizer.
5799 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5801 Try to make the peephole optimizer smarter by maintaining
5802 an association between the assembly source code and the
5803 iCodes that originated them. Put this information to use
5804 with a new peephole rule condition "notVolatile" so that
5805 the rules can be aggressive yet still safe.
5810 * src/mcs51/peeph.def
5812 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5816 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5817 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5818 if the left or right operand symbols have the accuse flag set.
5820 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5822 Changed the type of the result of the ! (NOT) operator to char;
5823 previously it returned the same type as the source. This allows
5824 us to eliminate all the genFloatNot functions (all of its target
5825 implementations were very buggy) since !float can use the same
5828 * src/SDCCicode.c (ast2iCode): ! returns char

5835 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5837 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5838 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5839 during interrupts. Ensure WSAVE is located at a shared bank address.
5840 2. Fixed page selection in some places
5841 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5842 the registers name strings.
5843 4. Fixed "signed / unsigned compare" compiler warnings.
5844 5. The PIC port manages its own allocation of the general purpose
5845 registers, but makes no attempt to reuse them. As a result when
5846 compiling it soon runs out of general purpose registers. Some
5847 additional code was added to the files pcode.c and device.c to walk
5848 through the function call tree and rename the registers so that they
5858 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5859 genPlus() & genMinus() when the result is the same as left or right

5865 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5867 Made bitfield a distinct type from bit so that bitfields
5868 convert as per ANSI C and bits retain their traditional
5869 boolean style behaviour. Implemented bitfield support in
5877 * src/ds390/gen.c: bit v bitfield split
5878 * src/z80/gen.c: New support for bitfields
5879 * support/regression/tests/bitfields.c: reenabled z80,
5882 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5884 Rules 246.x, 247.x relate to bitfields, the others speed up
5885 access to xdata mapped I/O devices.
5887 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5889 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5891 Cleaned up genPackBits and genUnpackBits and added two helper
5892 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5893 for literal assignments in genPackBits (thanks to Frieder for
5899 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5901 Fixed bug #748310 (pointer to function type mishandled when the
5902 function name is omitted). Also fixed a SIGSEGV when a function
5903 attribute (reentrant, etc) is used on a non-function or on a
5904 function but misplaced before the parameter list.
5906 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5908 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5909 * support/Util/SDCCerr.h,
5910 * support/Util/SDCCerr.c: Added func attr misuse error msg

5931 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5933 Made the constant following the "interrupt" keyword optional. If
5934 omitted, the function will not automatically be given an entry
5935 in the interrupt vector table (similar to #pragma NOIV, but
5936 less syntacticly kludgy). The interrupt number is also now
5937 range checked. Also fixed a bug in the high order bit example

5951 * src/SDCCicode.c (operandOperation): rewritten some ops
5952 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5953 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5955 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5956 be re-activated by defining REDUCE_LITERALS)

5958 unsigned, but are signed by default
5959 * src/SDCCval.c (constVal): rearranged
5960 * src/SDCCval.c (valMod): preliminary fix
5961 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6467 added if/endif conditional macros to remove options help
6468 messages from optionsTable when a port is not configured, added
6469 support for the PIc16 port in the ports table, when executing
6470 the compiler with no port specified on command line, a default
6471 port is selected with the new macro DEFAULT_PORT which is
6472 defined in port.h, in setDefaultOptions() linkOptions is removed
6473 from initialization assignment, since now it is a set,
6474 parseCmdLine uses setParseWithComma for linkOptions, in
6475 linkEdit() linkOptions are accessed with new function indexSet()
6476 which returns the i'th item of a set variable. See SDCCset.c, in
6477 linkEdit() when calling buildCmdLine(), added linkOptions as
6478 last argument. Now users can pass arguments to gplink via the
6479 -Wl option, main() uses pic16glue() to glue up pic16 programs

6492 * src/pic16/main.c: __config directives are commented out to stop
6493 gpasm complaining and test the linkage with gplink, _linkCmd and
6494 _asmCmd changed to be more gplink and gpasm friendly
6495 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6496 produced an error when parsed, peep rule 12 is added to utilize
6497 movff, but it is commented out since the pCode does not support
6498 yet a command with 2 address arguments
6500 2003-05-18 <johan AT balder>
6502 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7541 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7543 2003-01-04 <johan AT balder>
7545 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7547 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

7560 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7561 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7563 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7565 * in \sdcc\as\mcs51\ changed these files in order to create an
7566 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7567 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7568 following files to include the previous two files: aslink.dsp,
7569 Makefile.aslink, Makefile.bcc, and Makefile.in.
7571 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7572 .adb instead of .cdb
7574 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7576 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7577 value from option --iram-size.
7579 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7581 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7584 2002-09-18 <wiml AT hhhh.org>
7586 * SDCClrange.h: exposed setFromRange() and setToRange()
7587 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7588 packRegsForAccUse() (bug 542397)
7589 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7590 multiple times and emitting the fetch operations more than once
7591 added aopGetUsesAcc() function to allow binary operators to
7592 fetch their operands in the correct order; made genMinus() emit
7593 compact code for X = LITERAL - Y
7595 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7596 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7597 sprintf() in line 1267.
7599 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7600 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7603 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7604 Changes to aslink (All the changes are marked with 'JCF'):
7606 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7609 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7610 area BSEG. Also moves, if possible, the DATA area down into the internal
7611 ram so more space is available.
7613 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7616 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7617 not bytes. Function summary() which creates a memory usage summary
7618 file with extension .mem. Reports of overlaping stack and small stack
7619 size. If the space for the stack is less than 16 bytes aslink trows a
7622 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7623 the 8051. Option 'y' for memory summary output file.
7625 Changes to sdcc (All the changes are marked with 'JCF'):
7627 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7629 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7630 overlaying area for it (uses RegBankUsed[4]).
7632 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7633 bank zero as used by default. By default aslink locates the stack
7634 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7635 the creation of the .mem file. Delegates the allocation of data area
7636 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7637 the begining of the stack area to aslink.
7639 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7640 glue() in SDCCglue.c creates an area for it.
7642 2002-09-03 Borut Razem <borut.razem AT siol.net>
7643 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7644 sdcc/src/pic/glue.c:
7645 introduced atexit() handler for teporay files removal in case of
7646 errors, assertions, ...
7648 2002-08-29 Borut Razem <borut.razem AT siol.net>
7649 * sdcc/support/cpp2/auto-host_vc_in.h:
7650 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7651 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7652 Maybe there is a similar problem with BORLANDC? It should be checked!
7654 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7655 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7656 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7657 was not executed, and the compiler (cl) launched a warning:
7658 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7660 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7661 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7663 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7664 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7666 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7667 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7668 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7669 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7670 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7671 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7672 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7673 - added Release configuration in VS projects
7674 - review of compiler an linker options
7675 - VC .exe files are generated in bin_vc directory, not to interfere
7676 with binaries generated from other projects (cygwin, mingw, bcc ...)
7678 * sdcc/src/yacc.dsp: added
7680 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7681 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7682 and insert the version number definitions from .version
7684 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7686 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7687 added - genarate auto-host.h using auto-host_vc_in.h as template
7690 removed from CVS, generated automatically
7692 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7693 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7695 2002-08-11 Borut Razem <borut.razem AT siol.net>
7696 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7698 2002-08-10 Borut Razem <borut.razem AT siol.net>
7699 * src/SDCCmain.c (main):
7700 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7701 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7702 The consequence was that some temporary files were not removed.
7705 unification of code in functions tempfilename() and tempfile():
7706 function tempnam() is defined in Visual Studio 6.0 and .NET
7708 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7710 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7711 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7712 - removed compiler command line option /WX: Treats all warnings as errors
7713 - update a list of source files, included into the project
7715 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7716 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7717 changed project type to Generic Project so that can be correcly converted to VS.NET project
7719 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7721 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7723 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7725 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7726 added return 0 statements after assert() to make compiler happy
7728 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7729 added newline in the def file to keep MSC compiler satisfied
7731 * sdcc/src/z80/gen.c:
7732 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7733 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7734 - solved MSC error in function aopDump()
7736 * sdcc_vc.h: define PREFIX as "\\sdcc"
7738 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7739 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7741 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7742 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7743 - Rewrote the register banking algorithm.
7744 - Added pCode live-range analysis to registers (for now, only non-used and
7745 singly-used registers optimized away)
7747 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7749 * 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.

7778 2002-03-28 Johan Knol <johan AT balder>
7780 * src/SDCCval.c: fixed bug #532436
7782 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7784 Added "char *Processor" field to the port structure.
7787 Added -p option. Allows port dependent processor to be specified.
7790 Initialized the new field char *Processor field to NULL in all ports
7793 Compiler generated registers for interrupt context saving
7794 were not getting allocated.
7796 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7799 Fixed left shift. Will promote the left side of a left shift
7800 if a) left shifting more than size of operand or b) when assigned
7801 to something size > size of left side
7803 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7805 tons of changes. Register allocation has been
7806 rewritten. Added customization for the various PICs. Flow
7807 analysis is restructured. ...
7813 Added. device.c is a PIC port hack to accomodate variations
7816 2002-03-13 Michael Hope <michaelh AT vroom>
7818 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7820 2002-03-04 johanknol <johanknol AT manik>
