584 on rIfx (genCmp was broken)
586 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
588 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
589 * src/z80/main.c (_keywords[]),
590 * src/SDCCglobal.h (struct options),

677 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
679 * device/lib/printf_large.c: removed inline assembly for portability and
680 readability. Use printf_fast if speed or size are more important.
681 * src/pic16/gen.c: removed conditions around use of DEBUGpc
682 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
684 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
686 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
687 prevent compiler warning
689 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
691 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
692 moved to level 0 and declared as static. Also they are explicit
693 placed in access bank. This was necessery because some times they
694 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
695 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
696 optimizations. Currently only compare to unsigned char is implemented,
697 * src/pic16/gen.c: added fReturnIdx array,
698 * (struct resolvedIfx) is moved to gen.h and made public,
699 * (struct _G): added sregsAlloc and sregsAllocSet fields,
700 * (aopForSym): added an optimization to directly store in stack of
701 the operand of a SEND iCode,
702 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
703 but as registers instead (AOP_REG) using the fReturnIdx array,
704 * (pic16_freeAsmop): remove the freed register from the
706 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
708 * (pic16_popGetTempRegCond): changed function prototype, now
709 function takes also a bitVector argument v which holds the current
710 set of registers that are allocated for stack access by aopForSym,
711 registers allocated in aopForSym for accessing stack symbols are not
712 any more part of the functions usedRegs field,
713 * (genCall): some times aopOp is called for a stack variable to be
714 send, aopForSym might perform the push, if this is true make sure
715 that genCall doesn't push the variable twice by testing _G.resDirect,
716 * (genFunction): changed testing for unspecified interrupt number
717 from 256 to INTNO_UNSPEC,
718 * modified selection scheme of frame pointer generation. Previously
719 if function did use local registers a frame pointer was generated,
720 now a frame pointer is generated only if function has arguments
721 (that need PLUSW2 register access), or has stack arguments, or the
722 compiler is not instructed to omit the frame pointer,
723 * (genEndFunction): before restoring local registers that were saved
724 in the function preamble, also restore the registers that *might*
725 have been allocated for stack access,
726 * (genRet): removed some old comments,
727 * (genCmp, the active (RN's) version): added a call to the
728 pic16_genCmp_special function to perform the compare with a more
729 robust and optimized way,
730 * (genInline): a feature has been added in inline code generation,
731 which allows a wildcard variable substitution when writing inline
732 assembly. Code is incomplete and experimental therefore undocumented,
733 * (genCast): changed order of aopOp for result and right to allow
734 aopForSym to directly load the result if possible,
735 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
736 perform an optimized compare on some selected special occasions,
737 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
738 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
739 generate an IVT any more,
740 * src/pic16/main.c (pic16_optionsTable): added command line option
742 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
743 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
745 * src/pic16/NOTES: Raphael Neider added in list of active developers
746 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
747 jumptable_end to prevent bug #,
748 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
749 inCond and outCond fields,
750 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
751 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
752 turn off register spilling,
753 * (packRegsForOneUse): synced with other ports' versions although it
754 is not used currently,
755 * (pic16_packRegisters): added an optimization while reading
756 structure bitfields, some registers may be saved (malloc code is
757 decreased by 80 bytes)
759 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
761 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
762 left is a bitfield, if yes, then don't optimize assignment. Perhaps
763 this can be optimized more?
765 2005-03-10 Raphael Neider <rneider AT web.de>
767 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
768 genNearPointerGet): (hopefully) fixed access to bitfields via
769 pointers (p->bitN = x; and x = p->bitN; failed)
771 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
773 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

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

1403 Adding support for replacing ljmps with sjmps in jumptables
1404 generated for switch statements. For now you need to set the
1405 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1406 Now 4 algorithms for mcs51 jumptable generation are used:
1407 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1408 addresses loaded pc-relative for up to 112 cases and stack-pushing
1409 target addresses loaded with offset from dptr for up to 256 cases.

1439 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1441 * added libc directory. The current version of LibC contains string
1442 functions, ctype functions and macros and some functions of the
1443 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1444 be extensively tested in the future. Standard disclaimer here.
1445 Library is not automatically build yet. But one can build it by
1446 invoking 'make' inside the libc directory.
1447 * added ADC library under libio. Preliminary version yet.

1456 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1457 * (pic16_storeForReturn): optimized return of 0,
1458 * (genCmp): experimental code for new genCmp which uses PIC18's
1459 special compare&skip instructions. Initial tests fail some times
1460 with variables grater than 1 byte in size, so new code is disabled,
1461 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1463 * (genCast): began a fix to optimize the casting of a bit to another
1464 bit, now assigning a bitfield to another bitfield will fail, sorry,
1465 * src/pic16/main.c: disabled the use of lr-support feature,
1466 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

1469 bits with offset (case PO_GPR_BIT),
1470 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1472 * (isBankInstruction): modified to return 0 for no banking instruction,
1473 and 1 for banking instruction,
1474 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1475 caused stop processing pCodes after a inline assembly block,
1476 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1477 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1478 registers when it shouldn't,
1479 * src/pic16/ralloc.c (allocReg): add preliminary support for
1480 supporting a limited set of temporary registers,
1482 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1484 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1485 genDataPointerSet): ensure assignments always copy in MSB to LSB
1487 (loadRegFromAop): recognize CLRH optimization,
1488 (genFunction): optimize RECEIVE iCodes in reentrant functions
1490 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1492 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4439 * src/pic/ralloc.h: applied patch from Slade Rich;
4440 added support for multiple code pages and multiple RAM banks on the
4441 PIC 14 port. The ASM files now no longer simply assume all the
4442 code / RAM are in the same page / bank. This means the linker can
4443 safely allocate code/RAM of separate ASM files to different pages/banks.
4444 * doc/sdccman.lyx: added Slade's tips
4445 * src/mcs51/peeph.def: fixed bug #880768

4454 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
4457 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
4458 strtof is not part of C89 and isn't included with Mac OS X.
4460 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4462 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,
4463 shiftL2Left2Result): fixed bug #879326
4464 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY

4487 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4489 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4490 loaded with the linker search paths (-L arguments) and the libraries
4491 to be linked with the current source (-l arguments). Changes
4492 currently will affect only the pic16 port.
4493 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4494 include path the port specific paths and port specific libraries,
4495 * gplink command now contains the $3 argument,
4496 * src/pic16/device.h,
4497 * src/pic16/device.c,: structure PIC_device is made public and
4498 renamed to PIC16_device, the same for variable Pics which is renamed
4499 to Pics16. Updated all references to them.
4500 * src/pic16/glue.c (pic16glue): corrected bug with code
4501 initialization which bypassed the variable initializations block.

4511 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
4513 Documenting changes from previous commits.
4514 * configure.in (version 1.56),
4515 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4516 when generating output files to configure the pic16 library,
4517 but now I've commented it out, since gputils aren't installed in the
4518 SF compile farm, so library won't compile
4520 * device/lib/Makefile.in (version 1.56): initially I've added in
4521 target 'all' the prerequestive 'model-pic16' so it compiled the
4522 pic16 library, but now I've commented it out for the same reasons
4524 * added targets 'model-pic16' and 'objects-pic16' to compile the
4526 * added target 'port-specific-objects-pic16' to handle the
4527 generated libraries and copy them into the build/ directory
4528 * added target 'clean-intermediate-pic16' to clean intermediate
4529 files into pic16 directory
4530 * in target 'installdirs' added line to create directory pic16 in
4531 the installation path
4533 * device/include/Makefile.in (version 1.11): in target 'install'
4534 added lines to copy all header files to installation path,
4535 * in target 'installdirs' added line create directory for pic16
4536 headers in the installation path

4551 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4552 option so that it actually works. Made it specific to the z80, since
4553 the gbz80 doesn't have these kinds of I/O ports.
4555 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4557 * device/include/z180.h,

4570 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4572 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
4573 changed interrupt vector table generation to only emit declared vectors.

4579 Mainly changes to support compilation of the device libraries
4580 * src/pic16/device.c: stack is allocated via symbol and not
4581 via literal number. The symbol is placed in the corresponding
4582 position of the data ram
4583 * (pic16_dump_section): relocatable and absolute uninitialized
4584 data are now emitted in sorted order to reduce section naming,
4585 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4586 weren't marked as being in the access bank,
4588 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4590 Added portion of GNU PIC Library under the directory
4591 device/include/pic16 and device/lib/pic16. These files
4592 contain the declarations of SFRs for the PIC18Fxx2 devices.
4593 The directory is initialized via configure from toplevel.
4595 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4597 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
4598 the spilllocations to be compared correctly

4623 all over. Telling LaTeX to be less strict with word spacing
4624 to better keep the right margin. Changed some notes about
4625 maintainance of the ports in section 3.2.1 - is it OK like this?
4627 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4665 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4667 * src/pic16/peeph.def: all peepholes with movff are commented out,
4668 because there is a problem in the pcode peep optimizer,
4669 * src/pic16/ralloc.c: the register allocator can now reuse local

4784 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4786 A python script to validate compiler diagnostic messages. It can be
4787 used to verify that sdcc complains about bad c source code and
4788 gives a good location of the error.
4789 * support/valdiag/Makefile,
4790 * support/valdiag/valdiag.py,
4791 * support/valdiag/tests/*

4808 Bug reported from Jesus Calvino-Fraga
4810 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4812 * sdcc.spec: updated

4821 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4823 PIC16 port related changes:
4824 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4825 added variable stackPos,
4827 * gen.c: genCall, assignResultValue: added support for
4828 pushing/retrieving function parameters to/from stack,
4829 genFunction,genEndFunction: setup stack frame for the
4831 genAddrOf: will be changed according to bug 863624
4833 * added files genutils.c and genutils.h which contain gen*
4834 debugged and optimised functions extracted from gen.c
4836 * glue.c: added variable 'externs' which holds extern symbols,
4837 pic16emitRegularMap: is modified to properly handle relocatable
4838 symbols under the new scheme,
4839 pic16createInterruptVect: is modified
4840 pic16printPublics: is modified to emit 'global' assembler directives,
4841 added pic16_printExterns to print extern symbols,
4842 pic16glue: initializes stack/frame pointer in the beginning of
4843 the assembly output. Temporary hack, will be corrected later,
4844 because gplink yet does not support stack and SDCC does not
4845 yet support a type of crt0.o object to create the final binary.
4847 * Removed many lines that contain 8051 legacy code.
4848 * The code is finally placed under a 'code' directive.
4849 * Added port specific options.
4851 * _process_pragma: simplified since now we do not need *special*
4852 include file to define SFR registers. But a separate header
4853 will be needed. This will be developed later.
4854 * _pic16_parseOptions: added, parses port specific options:
4855 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4856 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4857 --preplace-udata-with=
4859 * _pic16_setDefaultOptions: modified to initialize section names,
4860 but hack is temporarly out of order since it needs improvement.
4861 * _pic16_genAssemblerPreamble: configuration words are emitted by
4862 their address instead of their name. This part is incomplete and
4863 supports only the 18Fxx2 devices. Other devices will emit an error
4864 during assembly since they do not contain the same set of config
4866 * _pic16_genIVT: is modified,
4868 * pcode.c: added definitions for some hardware registers that are needed
4870 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4871 All PCI entries are updated. Now LFSR is supported.
4872 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4873 * added pic16_newpCodeOpLit2 to support instructions with
4874 two literal arguments
4875 * pic16_pCode2str: corrected code that emits assembler instructions
4876 with two literal operands and those that have an access bit modifier
4877 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4878 this fixes a bug which caused some labels to be lost, when an
4879 assembler directive was added, i.e. banksel,
4880 * pic16_FixRegisterBanking: improved logic that causes the insertion
4882 * InlineFunction: functions that are called once, are not any more
4883 inlined. This can be a port option in the future,
4885 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4887 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4888 hold the corresponding uninitialized symbols,
4889 * pic16_allocProcessorRegister: registers have explicit marked the
4891 * pic16_allocInternalRegister: registers are explicit marked as
4893 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4894 processing list, so bit registers were lost,
4897 * ralloc.h: added field 'accessBank' and original symbol operand
4898 in register definition,
4899 * removed the field isMapped from register definition,
4901 ** Several functions have been removed from various sources:
4902 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4903 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4904 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4905 pic16_assignRelocatableRegisters
4907 ** others have been introduced:
4908 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4909 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4911 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4913 * support/scripts/inc2h.pl: changed definition of BIT_AT
4914 to emit 'sbit at' instead of 'bit at'. This was a request.
4916 PIC16 port related preliminary changes:
4917 * gen.c: prefixed function popRegFromString with
4918 pic16_ and all references to it corrected
4919 * pcode.c: all pic16_pc_* hardware registers prefixed
4920 with underscore (_),
4921 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4922 * ralloc.c: newReg(): when register is REG_SFR then
4923 set address to rIdx,
4924 pic16_allocProcessorRegister(): marks register wasUsed=0
4925 pic16_writeUsedRegs(): added a call to assign processor
4926 registers via pic16_assignFixedRegisters
4928 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4930 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4931 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4932 variables in unused register banks. Also the SSEG is placed
4933 wherever there is enough space for it, and IDATA can be anywhere
4934 in internal RAM. For now compile using -Wl-Y[stack_size].
4935 The mem file is different for this option as well, since it
4936 makes no sense of talking about DSEG lenght.
4938 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>

5931 and JUMPTABLE iCodes properly now (worked by accident before)
5932 * src/mcs51/gen.c (leftRightUseAcc),
5933 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
5934 iCode properly now. Use getSize instead of nRegs since a & b
5935 aren't part of the nRegs tally.
5937 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
5939 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

5945 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5946 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5947 fetching of the pointer
5948 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5949 copied from genNearPointerSet()
5950 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5951 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5952 If they pop r0/r1 they must be called in the opposite order than aopOp().
5953 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5954 (resp. --stack-auto), prepared for --xstack

5965 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5967 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5968 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5969 type for bits was changed. It resulted in bit variables becoming
5970 global, which is not permitted in PIC 14 assembly output.
5972 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5974 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5987 A few small changes that speed up the peephole optimizer.
5991 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5993 Try to make the peephole optimizer smarter by maintaining
5994 an association between the assembly source code and the
5995 iCodes that originated them. Put this information to use
5996 with a new peephole rule condition "notVolatile" so that
5997 the rules can be aggressive yet still safe.
6002 * src/mcs51/peeph.def
6004 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6008 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6009 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6010 if the left or right operand symbols have the accuse flag set.
6012 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6014 Changed the type of the result of the ! (NOT) operator to char;
6015 previously it returned the same type as the source. This allows
6016 us to eliminate all the genFloatNot functions (all of its target
6017 implementations were very buggy) since !float can use the same
6020 * src/SDCCicode.c (ast2iCode): ! returns char

6029 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6030 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6031 during interrupts. Ensure WSAVE is located at a shared bank address.
6032 2. Fixed page selection in some places
6033 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6034 the registers name strings.
6035 4. Fixed "signed / unsigned compare" compiler warnings.
6036 5. The PIC port manages its own allocation of the general purpose
6037 registers, but makes no attempt to reuse them. As a result when
6038 compiling it soon runs out of general purpose registers. Some
6039 additional code was added to the files pcode.c and device.c to walk
6040 through the function call tree and rename the registers so that they
6050 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6051 genPlus() & genMinus() when the result is the same as left or right

6057 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6059 Made bitfield a distinct type from bit so that bitfields
6060 convert as per ANSI C and bits retain their traditional
6061 boolean style behaviour. Implemented bitfield support in
6069 * src/ds390/gen.c: bit v bitfield split
6070 * src/z80/gen.c: New support for bitfields
6071 * support/regression/tests/bitfields.c: reenabled z80,
6074 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6076 Rules 246.x, 247.x relate to bitfields, the others speed up
6077 access to xdata mapped I/O devices.
6079 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6081 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6083 Cleaned up genPackBits and genUnpackBits and added two helper
6084 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6085 for literal assignments in genPackBits (thanks to Frieder for
6091 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6093 Fixed bug #748310 (pointer to function type mishandled when the
6094 function name is omitted). Also fixed a SIGSEGV when a function
6095 attribute (reentrant, etc) is used on a non-function or on a
6096 function but misplaced before the parameter list.
6098 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6100 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6123 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6125 Made the constant following the "interrupt" keyword optional. If
6126 omitted, the function will not automatically be given an entry
6127 in the interrupt vector table (similar to #pragma NOIV, but
6128 less syntacticly kludgy). The interrupt number is also now
6129 range checked. Also fixed a bug in the high order bit example

6150 unsigned, but are signed by default
6151 * src/SDCCval.c (constVal): rearranged
6152 * src/SDCCval.c (valMod): preliminary fix
6153 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6605 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6606 the regression tests I'm not brave enough to enable 245.b, 245.c
6607 * doc/sdccman.lyx: added latex preamble for hyperref package.
6608 Using pdflatex this will give you a hyperlinked pdf file with
6609 bookmarks. (prepend '%' before /usepackage if this breaks something)

6645 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
6647 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6649 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6650 it can be defined with CFLAGS when running configure
6651 * src/SDCCmain.c: fixed compiling + linking with object files
6653 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
6655 * configure.in: configure for pic16 port,
6656 added --disable-pic16-port
6657 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6658 * src/SDCCmain.c: linkOptions is changed to set *,
6659 added if/endif conditional macros to remove options help
6660 messages from optionsTable when a port is not configured, added
6661 support for the PIc16 port in the ports table, when executing
6662 the compiler with no port specified on command line, a default
6663 port is selected with the new macro DEFAULT_PORT which is
6664 defined in port.h, in setDefaultOptions() linkOptions is removed
6665 from initialization assignment, since now it is a set,
6666 parseCmdLine uses setParseWithComma for linkOptions, in
6667 linkEdit() linkOptions are accessed with new function indexSet()
6668 which returns the i'th item of a set variable. See SDCCset.c, in
6669 linkEdit() when calling buildCmdLine(), added linkOptions as
6670 last argument. Now users can pass arguments to gplink via the
6671 -Wl option, main() uses pic16glue() to glue up pic16 programs
6672 * src/SDCCpeeph.c: various changes to support pic16

6679 added macro DEFAULT_PORT
6680 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
6681 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
6683 * src/pic16/glue.c: commented out some error producing lines
6684 * src/pic16/main.c: __config directives are commented out to stop
6685 gpasm complaining and test the linkage with gplink, _linkCmd and
6686 _asmCmd changed to be more gplink and gpasm friendly
6687 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6688 produced an error when parsed, peep rule 12 is added to utilize
6689 movff, but it is commented out since the pCode does not support
6690 yet a command with 2 address arguments
6692 2003-05-18 <johan AT balder>
6694 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
6695 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6721 2003-05-11 Borut Razem <borut.razem AT siol.net>
6723 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6724 the path of bin directory, so that PATH is the only env. variable, which has to be set
6725 in case of standard installation.
6726 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7755 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7757 * in \sdcc\as\mcs51\ changed these files in order to create an
7758 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7759 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7760 following files to include the previous two files: aslink.dsp,
7761 Makefile.aslink, Makefile.bcc, and Makefile.in.
7763 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7764 .adb instead of .cdb
7766 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7768 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7769 value from option --iram-size.
7771 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7773 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7776 2002-09-18 <wiml AT hhhh.org>
7778 * SDCClrange.h: exposed setFromRange() and setToRange()
7779 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7780 packRegsForAccUse() (bug 542397)
7781 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7782 multiple times and emitting the fetch operations more than once
7783 added aopGetUsesAcc() function to allow binary operators to
7784 fetch their operands in the correct order; made genMinus() emit
7785 compact code for X = LITERAL - Y
7787 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7788 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7789 sprintf() in line 1267.
7791 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7792 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7795 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7796 Changes to aslink (All the changes are marked with 'JCF'):
7798 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7801 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7802 area BSEG. Also moves, if possible, the DATA area down into the internal
7803 ram so more space is available.
7805 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7808 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7809 not bytes. Function summary() which creates a memory usage summary
7810 file with extension .mem. Reports of overlaping stack and small stack
7811 size. If the space for the stack is less than 16 bytes aslink trows a
7814 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7815 the 8051. Option 'y' for memory summary output file.
7817 Changes to sdcc (All the changes are marked with 'JCF'):
7819 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7821 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7822 overlaying area for it (uses RegBankUsed[4]).
7824 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7825 bank zero as used by default. By default aslink locates the stack
7826 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7827 the creation of the .mem file. Delegates the allocation of data area
7828 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7829 the begining of the stack area to aslink.
7831 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7832 glue() in SDCCglue.c creates an area for it.
7834 2002-09-03 Borut Razem <borut.razem AT siol.net>
7835 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7836 sdcc/src/pic/glue.c:
7837 introduced atexit() handler for teporay files removal in case of
7838 errors, assertions, ...
7840 2002-08-29 Borut Razem <borut.razem AT siol.net>
7841 * sdcc/support/cpp2/auto-host_vc_in.h:
7842 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7843 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7844 Maybe there is a similar problem with BORLANDC? It should be checked!
7846 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7847 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7848 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7849 was not executed, and the compiler (cl) launched a warning:
7850 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7852 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7853 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7855 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7856 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7858 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7859 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7860 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7861 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7862 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7863 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7864 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7865 - added Release configuration in VS projects
7866 - review of compiler an linker options
7867 - VC .exe files are generated in bin_vc directory, not to interfere
7868 with binaries generated from other projects (cygwin, mingw, bcc ...)
7870 * sdcc/src/yacc.dsp: added
7872 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7873 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7874 and insert the version number definitions from .version
7876 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7878 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

7887 2002-08-11 Borut Razem <borut.razem AT siol.net>
7888 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7890 2002-08-10 Borut Razem <borut.razem AT siol.net>
7891 * src/SDCCmain.c (main):
7892 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7893 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7894 The consequence was that some temporary files were not removed.
7897 unification of code in functions tempfilename() and tempfile():
7898 function tempnam() is defined in Visual Studio 6.0 and .NET
7900 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7902 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7903 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7904 - removed compiler command line option /WX: Treats all warnings as errors
7905 - update a list of source files, included into the project
7907 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7908 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7909 changed project type to Generic Project so that can be correcly converted to VS.NET project
7911 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7913 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7915 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7917 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7918 added return 0 statements after assert() to make compiler happy
7920 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7921 added newline in the def file to keep MSC compiler satisfied
7923 * sdcc/src/z80/gen.c:
7924 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7925 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7926 - solved MSC error in function aopDump()
7928 * sdcc_vc.h: define PREFIX as "\\sdcc"
7930 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7931 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7979 Added -p option. Allows port dependent processor to be specified.
7982 Initialized the new field char *Processor field to NULL in all ports
7985 Compiler generated registers for interrupt context saving
7986 were not getting allocated.
7988 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7991 Fixed left shift. Will promote the left side of a left shift
7992 if a) left shifting more than size of operand or b) when assigned
7993 to something size > size of left side
7995 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7997 tons of changes. Register allocation has been

8103 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8105 * sdcc/src/SDCCloop.c:
8106 Previous fix was not good. basic blocks that have "break" or "return" are
8107 not really partof a loop , but live ranges used in these blocks should
8108 be live thru the entire loop, so set partOfLoop but don't add them to
8111 2002-02-21 <johan AT FRIJA>
8113 * src/SDCCcse.c: fixed bug #514308
8115 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

8121 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8123 2002-02-10 Karl Bongers <karl AT turbobit.com>

8134 for use as a multiple module SDCDB test case.
8136 * sim/ucsim/cmd.src/cmdset.cc:
8137 Took out debug printfs in ucsim "next" command.
8140 Karl and Johan start ucsim XA support. Most dissassembly working,
8141 about 75% emulation done(plenty of work remaining).
8143 * sim/ucsim/z80.src:
8144 Add Z80 support to ucsim, add test-ucz80 regression test,
8145 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
