716 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
718 * device/lib/printf_large.c: removed inline assembly for portability and
719 readability. Use printf_fast if speed or size are more important.
720 * src/pic16/gen.c: removed conditions around use of DEBUGpc
721 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
723 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
725 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
726 prevent compiler warning
728 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
730 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
731 moved to level 0 and declared as static. Also they are explicit
732 placed in access bank. This was necessery because some times they
733 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
734 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
735 optimizations. Currently only compare to unsigned char is implemented,
736 * src/pic16/gen.c: added fReturnIdx array,
737 * (struct resolvedIfx) is moved to gen.h and made public,
738 * (struct _G): added sregsAlloc and sregsAllocSet fields,
739 * (aopForSym): added an optimization to directly store in stack of
740 the operand of a SEND iCode,
741 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
742 but as registers instead (AOP_REG) using the fReturnIdx array,
743 * (pic16_freeAsmop): remove the freed register from the
745 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
747 * (pic16_popGetTempRegCond): changed function prototype, now
748 function takes also a bitVector argument v which holds the current
749 set of registers that are allocated for stack access by aopForSym,
750 registers allocated in aopForSym for accessing stack symbols are not
751 any more part of the functions usedRegs field,
752 * (genCall): some times aopOp is called for a stack variable to be
753 send, aopForSym might perform the push, if this is true make sure
754 that genCall doesn't push the variable twice by testing _G.resDirect,
755 * (genFunction): changed testing for unspecified interrupt number
756 from 256 to INTNO_UNSPEC,
757 * modified selection scheme of frame pointer generation. Previously
758 if function did use local registers a frame pointer was generated,
759 now a frame pointer is generated only if function has arguments
760 (that need PLUSW2 register access), or has stack arguments, or the
761 compiler is not instructed to omit the frame pointer,
762 * (genEndFunction): before restoring local registers that were saved
763 in the function preamble, also restore the registers that *might*
764 have been allocated for stack access,
765 * (genRet): removed some old comments,
766 * (genCmp, the active (RN's) version): added a call to the
767 pic16_genCmp_special function to perform the compare with a more
768 robust and optimized way,
769 * (genInline): a feature has been added in inline code generation,
770 which allows a wildcard variable substitution when writing inline
771 assembly. Code is incomplete and experimental therefore undocumented,
772 * (genCast): changed order of aopOp for result and right to allow
773 aopForSym to directly load the result if possible,
774 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
775 perform an optimized compare on some selected special occasions,
776 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
777 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
778 generate an IVT any more,
779 * src/pic16/main.c (pic16_optionsTable): added command line option
781 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
782 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
784 * src/pic16/NOTES: Raphael Neider added in list of active developers
785 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
786 jumptable_end to prevent bug #,
787 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
788 inCond and outCond fields,
789 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
790 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
791 turn off register spilling,
792 * (packRegsForOneUse): synced with other ports' versions although it
793 is not used currently,
794 * (pic16_packRegisters): added an optimization while reading
795 structure bitfields, some registers may be saved (malloc code is
796 decreased by 80 bytes)
798 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
800 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
801 left is a bitfield, if yes, then don't optimize assignment. Perhaps
802 this can be optimized more?
804 2005-03-10 Raphael Neider <rneider AT web.de>
806 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
807 genNearPointerGet): (hopefully) fixed access to bitfields via
808 pointers (p->bitN = x; and x = p->bitN; failed)
810 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
812 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

853 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
854 to keep the correct label reference count when adding/removing references
855 to labels. A peephole file using this is appended to patch #1144962.

1442 Adding support for replacing ljmps with sjmps in jumptables
1443 generated for switch statements. For now you need to set the
1444 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1445 Now 4 algorithms for mcs51 jumptable generation are used:
1446 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1447 addresses loaded pc-relative for up to 112 cases and stack-pushing
1448 target addresses loaded with offset from dptr for up to 256 cases.

1478 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1480 * added libc directory. The current version of LibC contains string
1481 functions, ctype functions and macros and some functions of the
1482 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1483 be extensively tested in the future. Standard disclaimer here.
1484 Library is not automatically build yet. But one can build it by
1485 invoking 'make' inside the libc directory.
1486 * added ADC library under libio. Preliminary version yet.

1496 * (pic16_storeForReturn): optimized return of 0,
1497 * (genCmp): experimental code for new genCmp which uses PIC18's
1498 special compare&skip instructions. Initial tests fail some times
1499 with variables grater than 1 byte in size, so new code is disabled,
1500 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1502 * (genCast): began a fix to optimize the casting of a bit to another
1503 bit, now assigning a bitfield to another bitfield will fail, sorry,
1504 * src/pic16/main.c: disabled the use of lr-support feature,
1505 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

1508 bits with offset (case PO_GPR_BIT),
1509 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1511 * (isBankInstruction): modified to return 0 for no banking instruction,
1512 and 1 for banking instruction,
1513 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1514 caused stop processing pCodes after a inline assembly block,
1515 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1516 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1517 registers when it shouldn't,
1518 * src/pic16/ralloc.c (allocReg): add preliminary support for
1519 supporting a limited set of temporary registers,
1521 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1523 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1524 genDataPointerSet): ensure assignments always copy in MSB to LSB
1526 (loadRegFromAop): recognize CLRH optimization,
1527 (genFunction): optimize RECEIVE iCodes in reentrant functions
1529 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1531 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4432 * support/regression/generate-cases.py (main): Changed from inline
4435 * doc/Makefile (install): Changed to depth first to get rid of
4436 missing directory install warning.
4438 * as/Makefile (install-doc): Made work on Mac.
4440 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
4442 * src/SDCCast.c: added an additional type flow in decorateType() of
4443 opposite direction, see feature request #860006; it's enabled at runtime
4444 by setting the environment variable SDCC_NEWTYPEFLOW
4445 * src/SDCCast.h: changed prototype of decorateType()
4446 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
4447 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
4448 'char' to 'int' can be omitted, if both operands are 'unsigned char';
4449 see feature request #877103
4450 * src/SDCCval.c: updated call of decorateType()
4451 (valBitwise): fixed bug #882876
4452 (valMinus): added promotion
4453 (valLogicAndOr): result is unsigned
4454 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
4455 * src/SDCCsymt.c (computeType),
4456 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
4457 must not cause an unsigned operation
4458 * src/pic/glue (pic14emitRegularMap),
4459 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
4461 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

4478 * src/pic/ralloc.h: applied patch from Slade Rich;
4479 added support for multiple code pages and multiple RAM banks on the
4480 PIC 14 port. The ASM files now no longer simply assume all the
4481 code / RAM are in the same page / bank. This means the linker can
4482 safely allocate code/RAM of separate ASM files to different pages/banks.
4483 * doc/sdccman.lyx: added Slade's tips
4484 * src/mcs51/peeph.def: fixed bug #880768

4493 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
4496 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
4497 strtof is not part of C89 and isn't included with Mac OS X.
4499 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4501 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

4526 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4528 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4529 loaded with the linker search paths (-L arguments) and the libraries
4530 to be linked with the current source (-l arguments). Changes
4531 currently will affect only the pic16 port.
4532 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4533 include path the port specific paths and port specific libraries,
4534 * gplink command now contains the $3 argument,
4535 * src/pic16/device.h,
4536 * src/pic16/device.c,: structure PIC_device is made public and
4537 renamed to PIC16_device, the same for variable Pics which is renamed

4552 Documenting changes from previous commits.
4553 * configure.in (version 1.56),
4554 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4555 when generating output files to configure the pic16 library,
4556 but now I've commented it out, since gputils aren't installed in the
4557 SF compile farm, so library won't compile
4559 * device/lib/Makefile.in (version 1.56): initially I've added in
4560 target 'all' the prerequestive 'model-pic16' so it compiled the
4561 pic16 library, but now I've commented it out for the same reasons
4563 * added targets 'model-pic16' and 'objects-pic16' to compile the
4565 * added target 'port-specific-objects-pic16' to handle the
4566 generated libraries and copy them into the build/ directory
4567 * added target 'clean-intermediate-pic16' to clean intermediate
4568 files into pic16 directory
4569 * in target 'installdirs' added line to create directory pic16 in
4570 the installation path
4572 * device/include/Makefile.in (version 1.11): in target 'install'
4573 added lines to copy all header files to installation path,
4574 * in target 'installdirs' added line create directory for pic16
4575 headers in the installation path

4590 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4591 option so that it actually works. Made it specific to the z80, since
4592 the gbz80 doesn't have these kinds of I/O ports.
4594 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4596 * device/include/z180.h,

4618 Mainly changes to support compilation of the device libraries
4619 * src/pic16/device.c: stack is allocated via symbol and not
4620 via literal number. The symbol is placed in the corresponding
4621 position of the data ram
4622 * (pic16_dump_section): relocatable and absolute uninitialized
4623 data are now emitted in sorted order to reduce section naming,
4624 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4625 weren't marked as being in the access bank,
4627 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4629 Added portion of GNU PIC Library under the directory
4630 device/include/pic16 and device/lib/pic16. These files
4631 contain the declarations of SFRs for the PIC18Fxx2 devices.
4632 The directory is initialized via configure from toplevel.
4634 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

4662 all over. Telling LaTeX to be less strict with word spacing
4663 to better keep the right margin. Changed some notes about
4664 maintainance of the ports in section 3.2.1 - is it OK like this?
4666 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4706 * src/pic16/peeph.def: all peepholes with movff are commented out,
4707 because there is a problem in the pcode peep optimizer,
4708 * src/pic16/ralloc.c: the register allocator can now reuse local

4849 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4851 * sdcc.spec: updated
4852 * device/include/Makefile.in: don't install CVS directories

4860 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4862 PIC16 port related changes:
4863 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4864 added variable stackPos,
4866 * gen.c: genCall, assignResultValue: added support for
4867 pushing/retrieving function parameters to/from stack,
4868 genFunction,genEndFunction: setup stack frame for the
4870 genAddrOf: will be changed according to bug 863624
4872 * added files genutils.c and genutils.h which contain gen*
4873 debugged and optimised functions extracted from gen.c
4875 * glue.c: added variable 'externs' which holds extern symbols,
4876 pic16emitRegularMap: is modified to properly handle relocatable
4877 symbols under the new scheme,
4878 pic16createInterruptVect: is modified
4879 pic16printPublics: is modified to emit 'global' assembler directives,
4880 added pic16_printExterns to print extern symbols,
4881 pic16glue: initializes stack/frame pointer in the beginning of
4882 the assembly output. Temporary hack, will be corrected later,
4883 because gplink yet does not support stack and SDCC does not
4884 yet support a type of crt0.o object to create the final binary.
4886 * Removed many lines that contain 8051 legacy code.
4887 * The code is finally placed under a 'code' directive.
4888 * Added port specific options.
4890 * _process_pragma: simplified since now we do not need *special*
4891 include file to define SFR registers. But a separate header
4892 will be needed. This will be developed later.
4893 * _pic16_parseOptions: added, parses port specific options:
4894 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4895 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4896 --preplace-udata-with=
4898 * _pic16_setDefaultOptions: modified to initialize section names,
4899 but hack is temporarly out of order since it needs improvement.
4900 * _pic16_genAssemblerPreamble: configuration words are emitted by
4901 their address instead of their name. This part is incomplete and
4902 supports only the 18Fxx2 devices. Other devices will emit an error
4903 during assembly since they do not contain the same set of config
4905 * _pic16_genIVT: is modified,
4907 * pcode.c: added definitions for some hardware registers that are needed
4909 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4910 All PCI entries are updated. Now LFSR is supported.
4911 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4912 * added pic16_newpCodeOpLit2 to support instructions with
4913 two literal arguments
4914 * pic16_pCode2str: corrected code that emits assembler instructions
4915 with two literal operands and those that have an access bit modifier
4916 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4917 this fixes a bug which caused some labels to be lost, when an
4918 assembler directive was added, i.e. banksel,
4919 * pic16_FixRegisterBanking: improved logic that causes the insertion
4921 * InlineFunction: functions that are called once, are not any more
4922 inlined. This can be a port option in the future,
4924 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4926 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4927 hold the corresponding uninitialized symbols,
4928 * pic16_allocProcessorRegister: registers have explicit marked the
4930 * pic16_allocInternalRegister: registers are explicit marked as
4932 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4933 processing list, so bit registers were lost,
4936 * ralloc.h: added field 'accessBank' and original symbol operand
4937 in register definition,
4938 * removed the field isMapped from register definition,
4940 ** Several functions have been removed from various sources:
4941 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4942 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4943 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4944 pic16_assignRelocatableRegisters
4946 ** others have been introduced:
4947 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4948 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4950 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4952 * support/scripts/inc2h.pl: changed definition of BIT_AT
4953 to emit 'sbit at' instead of 'bit at'. This was a request.
4955 PIC16 port related preliminary changes:
4956 * gen.c: prefixed function popRegFromString with
4957 pic16_ and all references to it corrected
4958 * pcode.c: all pic16_pc_* hardware registers prefixed
4959 with underscore (_),
4960 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4961 * ralloc.c: newReg(): when register is REG_SFR then
4962 set address to rIdx,
4963 pic16_allocProcessorRegister(): marks register wasUsed=0
4964 pic16_writeUsedRegs(): added a call to assign processor
4965 registers via pic16_assignFixedRegisters
4967 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4969 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4970 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4971 variables in unused register banks. Also the SSEG is placed
4972 wherever there is enough space for it, and IDATA can be anywhere
4973 in internal RAM. For now compile using -Wl-Y[stack_size].
4974 The mem file is different for this option as well, since it
4975 makes no sense of talking about DSEG lenght.
4977 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4979 * src/SDCClrange.c: fixed bug 869095 that caused segfault

5224 * src/SDCCast.c (decorateType): disabled a transformation I added in
5225 revision 1.188 (access to fields of a structure at an absolute address);
5226 it breaks with bitfields, extern declarations, and gcse analysis.
5227 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5228 could be assigned through a pointer, so don't complain.

5985 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5986 fetching of the pointer
5987 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5988 copied from genNearPointerSet()
5989 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5990 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6004 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6006 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6007 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6008 type for bits was changed. It resulted in bit variables becoming
6009 global, which is not permitted in PIC 14 assembly output.
6011 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6013 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6024 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6026 A few small changes that speed up the peephole optimizer.
6030 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6032 Try to make the peephole optimizer smarter by maintaining
6033 an association between the assembly source code and the
6034 iCodes that originated them. Put this information to use
6035 with a new peephole rule condition "notVolatile" so that
6036 the rules can be aggressive yet still safe.
6041 * src/mcs51/peeph.def
6043 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6047 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6048 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6049 if the left or right operand symbols have the accuse flag set.
6051 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6053 Changed the type of the result of the ! (NOT) operator to char;
6054 previously it returned the same type as the source. This allows
6055 us to eliminate all the genFloatNot functions (all of its target
6056 implementations were very buggy) since !float can use the same
6059 * src/SDCCicode.c (ast2iCode): ! returns char

6061 * src/ds390/gen.c (genNot, genNotFloat),
6062 * src/z80/gen.c (genNot, genNotFloat),
6063 * src/pic/gen.c (genNot, genNotFloat),

6066 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
6068 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6069 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6070 during interrupts. Ensure WSAVE is located at a shared bank address.
6071 2. Fixed page selection in some places
6072 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6073 the registers name strings.
6074 4. Fixed "signed / unsigned compare" compiler warnings.
6075 5. The PIC port manages its own allocation of the general purpose
6076 registers, but makes no attempt to reuse them. As a result when
6077 compiling it soon runs out of general purpose registers. Some
6078 additional code was added to the files pcode.c and device.c to walk
6079 through the function call tree and rename the registers so that they
6089 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6096 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6098 Made bitfield a distinct type from bit so that bitfields
6099 convert as per ANSI C and bits retain their traditional
6100 boolean style behaviour. Implemented bitfield support in
6108 * src/ds390/gen.c: bit v bitfield split
6109 * src/z80/gen.c: New support for bitfields
6110 * support/regression/tests/bitfields.c: reenabled z80,
6113 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6115 Rules 246.x, 247.x relate to bitfields, the others speed up
6116 access to xdata mapped I/O devices.
6118 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6120 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6122 Cleaned up genPackBits and genUnpackBits and added two helper
6123 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6124 for literal assignments in genPackBits (thanks to Frieder for
6130 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6132 Fixed bug #748310 (pointer to function type mishandled when the
6133 function name is omitted). Also fixed a SIGSEGV when a function
6134 attribute (reentrant, etc) is used on a non-function or on a
6135 function but misplaced before the parameter list.
6137 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6139 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6162 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6164 Made the constant following the "interrupt" keyword optional. If
6165 omitted, the function will not automatically be given an entry
6166 in the interrupt vector table (similar to #pragma NOIV, but
6167 less syntacticly kludgy). The interrupt number is also now
6168 range checked. Also fixed a bug in the high order bit example
6175 * support/Util/SDCCerr.c
6176 * support/Util/SDCCerr.h
6179 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

6182 * src/SDCCicode.c (operandOperation): rewritten some ops
6183 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6184 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6186 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6187 be re-activated by defining REDUCE_LITERALS)
6188 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6189 unsigned, but are signed by default
6190 * src/SDCCval.c (constVal): rearranged
6191 * src/SDCCval.c (valMod): preliminary fix
6192 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6644 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6645 the regression tests I'm not brave enough to enable 245.b, 245.c
6646 * doc/sdccman.lyx: added latex preamble for hyperref package.
6647 Using pdflatex this will give you a hyperlinked pdf file with
6648 bookmarks. (prepend '%' before /usepackage if this breaks something)

6689 it can be defined with CFLAGS when running configure
6690 * src/SDCCmain.c: fixed compiling + linking with object files
6692 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

6695 added --disable-pic16-port
6696 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6697 * src/SDCCmain.c: linkOptions is changed to set *,
6698 added if/endif conditional macros to remove options help
6699 messages from optionsTable when a port is not configured, added
6700 support for the PIc16 port in the ports table, when executing
6701 the compiler with no port specified on command line, a default
6702 port is selected with the new macro DEFAULT_PORT which is
6703 defined in port.h, in setDefaultOptions() linkOptions is removed
6704 from initialization assignment, since now it is a set,
6705 parseCmdLine uses setParseWithComma for linkOptions, in
6706 linkEdit() linkOptions are accessed with new function indexSet()
6707 which returns the i'th item of a set variable. See SDCCset.c, in
6708 linkEdit() when calling buildCmdLine(), added linkOptions as
6709 last argument. Now users can pass arguments to gplink via the
6710 -Wl option, main() uses pic16glue() to glue up pic16 programs

6722 * src/pic16/glue.c: commented out some error producing lines
6723 * src/pic16/main.c: __config directives are commented out to stop
6724 gpasm complaining and test the linkage with gplink, _linkCmd and
6725 _asmCmd changed to be more gplink and gpasm friendly
6726 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6727 produced an error when parsed, peep rule 12 is added to utilize
6728 movff, but it is commented out since the pCode does not support
6729 yet a command with 2 address arguments
6731 2003-05-18 <johan AT balder>
6733 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6760 2003-05-11 Borut Razem <borut.razem AT siol.net>
6762 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6763 the path of bin directory, so that PATH is the only env. variable, which has to be set
6764 in case of standard installation.

7847 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7848 not bytes. Function summary() which creates a memory usage summary
7849 file with extension .mem. Reports of overlaping stack and small stack
7850 size. If the space for the stack is less than 16 bytes aslink trows a
7853 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7854 the 8051. Option 'y' for memory summary output file.
7856 Changes to sdcc (All the changes are marked with 'JCF'):
7858 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7860 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7861 overlaying area for it (uses RegBankUsed[4]).
7863 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7864 bank zero as used by default. By default aslink locates the stack
7865 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7866 the creation of the .mem file. Delegates the allocation of data area
7867 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7868 the begining of the stack area to aslink.
7870 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7871 glue() in SDCCglue.c creates an area for it.
7873 2002-09-03 Borut Razem <borut.razem AT siol.net>
7874 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7875 sdcc/src/pic/glue.c:
7876 introduced atexit() handler for teporay files removal in case of
7877 errors, assertions, ...
7879 2002-08-29 Borut Razem <borut.razem AT siol.net>
7880 * sdcc/support/cpp2/auto-host_vc_in.h:
7881 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7882 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7883 Maybe there is a similar problem with BORLANDC? It should be checked!
7885 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7886 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7887 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7888 was not executed, and the compiler (cl) launched a warning:
7889 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7891 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7892 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7894 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7895 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7897 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7898 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7899 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7900 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7901 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7902 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7903 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7904 - added Release configuration in VS projects
7905 - review of compiler an linker options
7906 - VC .exe files are generated in bin_vc directory, not to interfere
7907 with binaries generated from other projects (cygwin, mingw, bcc ...)
7909 * sdcc/src/yacc.dsp: added
7911 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7912 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7913 and insert the version number definitions from .version
7915 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7917 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7918 added - genarate auto-host.h using auto-host_vc_in.h as template
7921 removed from CVS, generated automatically
7923 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7924 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7926 2002-08-11 Borut Razem <borut.razem AT siol.net>
7927 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7929 2002-08-10 Borut Razem <borut.razem AT siol.net>
7930 * src/SDCCmain.c (main):
7931 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7932 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7933 The consequence was that some temporary files were not removed.
7936 unification of code in functions tempfilename() and tempfile():
7937 function tempnam() is defined in Visual Studio 6.0 and .NET
7939 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7941 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7942 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7943 - removed compiler command line option /WX: Treats all warnings as errors
7944 - update a list of source files, included into the project
7946 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7947 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7948 changed project type to Generic Project so that can be correcly converted to VS.NET project
7950 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7952 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7954 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7956 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7957 added return 0 statements after assert() to make compiler happy
7959 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7960 added newline in the def file to keep MSC compiler satisfied
7962 * sdcc/src/z80/gen.c:
7963 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7964 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7965 - solved MSC error in function aopDump()
7967 * sdcc_vc.h: define PREFIX as "\\sdcc"
7969 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7970 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8013 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8015 Added "char *Processor" field to the port structure.
8018 Added -p option. Allows port dependent processor to be specified.
8021 Initialized the new field char *Processor field to NULL in all ports
8024 Compiler generated registers for interrupt context saving
8025 were not getting allocated.
8027 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8030 Fixed left shift. Will promote the left side of a left shift
8031 if a) left shifting more than size of operand or b) when assigned
8032 to something size > size of left side
8034 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8142 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8144 * sdcc/src/SDCCloop.c:
8145 Previous fix was not good. basic blocks that have "break" or "return" are
8146 not really partof a loop , but live ranges used in these blocks should
8147 be live thru the entire loop, so set partOfLoop but don't add them to
8150 2002-02-21 <johan AT FRIJA>
8152 * src/SDCCcse.c: fixed bug #514308
8154 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

8158 statement inside a loop, it was not being considered part of the loop.
8160 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8162 2002-02-10 Karl Bongers <karl AT turbobit.com>
8165 Fixed up SDCDB debugger somewhat. Updated debugger/README
8166 with lots of comments and notes.
8168 * device/examples/test2.c:
8169 Fix bug, "red" variable not being initialized(compiler complained).
