622 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
623 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
624 always available in leading double underscore form. The C99 support is
625 mostly missing, but it's a start.

705 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
707 * device/lib/printf_large.c: removed inline assembly for portability and
708 readability. Use printf_fast if speed or size are more important.
709 * src/pic16/gen.c: removed conditions around use of DEBUGpc
710 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
712 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
714 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
715 prevent compiler warning
717 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
719 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
720 moved to level 0 and declared as static. Also they are explicit
721 placed in access bank. This was necessery because some times they
722 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
723 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
724 optimizations. Currently only compare to unsigned char is implemented,
725 * src/pic16/gen.c: added fReturnIdx array,
726 * (struct resolvedIfx) is moved to gen.h and made public,
727 * (struct _G): added sregsAlloc and sregsAllocSet fields,
728 * (aopForSym): added an optimization to directly store in stack of
729 the operand of a SEND iCode,
730 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
731 but as registers instead (AOP_REG) using the fReturnIdx array,
732 * (pic16_freeAsmop): remove the freed register from the
734 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
736 * (pic16_popGetTempRegCond): changed function prototype, now
737 function takes also a bitVector argument v which holds the current
738 set of registers that are allocated for stack access by aopForSym,
739 registers allocated in aopForSym for accessing stack symbols are not
740 any more part of the functions usedRegs field,
741 * (genCall): some times aopOp is called for a stack variable to be
742 send, aopForSym might perform the push, if this is true make sure
743 that genCall doesn't push the variable twice by testing _G.resDirect,
744 * (genFunction): changed testing for unspecified interrupt number
745 from 256 to INTNO_UNSPEC,
746 * modified selection scheme of frame pointer generation. Previously
747 if function did use local registers a frame pointer was generated,
748 now a frame pointer is generated only if function has arguments
749 (that need PLUSW2 register access), or has stack arguments, or the
750 compiler is not instructed to omit the frame pointer,
751 * (genEndFunction): before restoring local registers that were saved
752 in the function preamble, also restore the registers that *might*
753 have been allocated for stack access,
754 * (genRet): removed some old comments,
755 * (genCmp, the active (RN's) version): added a call to the
756 pic16_genCmp_special function to perform the compare with a more
757 robust and optimized way,
758 * (genInline): a feature has been added in inline code generation,
759 which allows a wildcard variable substitution when writing inline
760 assembly. Code is incomplete and experimental therefore undocumented,
761 * (genCast): changed order of aopOp for result and right to allow
762 aopForSym to directly load the result if possible,
763 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
764 perform an optimized compare on some selected special occasions,
765 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
766 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
767 generate an IVT any more,
768 * src/pic16/main.c (pic16_optionsTable): added command line option
770 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
771 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
773 * src/pic16/NOTES: Raphael Neider added in list of active developers
774 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
775 jumptable_end to prevent bug #,
776 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
777 inCond and outCond fields,
778 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
779 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
780 turn off register spilling,
781 * (packRegsForOneUse): synced with other ports' versions although it
782 is not used currently,
783 * (pic16_packRegisters): added an optimization while reading
784 structure bitfields, some registers may be saved (malloc code is
785 decreased by 80 bytes)
787 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
789 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
790 left is a bitfield, if yes, then don't optimize assignment. Perhaps
791 this can be optimized more?
793 2005-03-10 Raphael Neider <rneider AT web.de>
795 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
796 genNearPointerGet): (hopefully) fixed access to bitfields via
797 pointers (p->bitN = x; and x = p->bitN; failed)
799 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
801 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

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

1431 Adding support for replacing ljmps with sjmps in jumptables
1432 generated for switch statements. For now you need to set the
1433 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1434 Now 4 algorithms for mcs51 jumptable generation are used:
1435 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1436 addresses loaded pc-relative for up to 112 cases and stack-pushing
1437 target addresses loaded with offset from dptr for up to 256 cases.

1464 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
1465 to call when a stack overflow occurs,
1466 * (malloc.h): added CVS Id tag,
1467 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1469 * added libc directory. The current version of LibC contains string
1470 functions, ctype functions and macros and some functions of the
1471 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1472 be extensively tested in the future. Standard disclaimer here.
1473 Library is not automatically build yet. But one can build it by
1474 invoking 'make' inside the libc directory.
1475 * added ADC library under libio. Preliminary version yet.
1477 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

1481 temporary registers, its a buggy feature and will be removed,
1482 * (pic16_popGet): set register instance field in AOP_CRY,
1483 * (pic16_outBitC): fixed for results in size greater than 1,
1484 * (genUminusFloat): fixed for pic16, ported code from mcs51,
1485 * (pic16_storeForReturn): optimized return of 0,
1486 * (genCmp): experimental code for new genCmp which uses PIC18's
1487 special compare&skip instructions. Initial tests fail some times
1488 with variables grater than 1 byte in size, so new code is disabled,
1489 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1491 * (genCast): began a fix to optimize the casting of a bit to another
1492 bit, now assigning a bitfield to another bitfield will fail, sorry,
1493 * src/pic16/main.c: disabled the use of lr-support feature,
1494 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

1497 bits with offset (case PO_GPR_BIT),
1498 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1500 * (isBankInstruction): modified to return 0 for no banking instruction,
1501 and 1 for banking instruction,
1502 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1503 caused stop processing pCodes after a inline assembly block,
1504 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1505 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1506 registers when it shouldn't,
1507 * src/pic16/ralloc.c (allocReg): add preliminary support for
1508 supporting a limited set of temporary registers,
1510 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1512 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1513 genDataPointerSet): ensure assignments always copy in MSB to LSB
1515 (loadRegFromAop): recognize CLRH optimization,
1516 (genFunction): optimize RECEIVE iCodes in reentrant functions
1518 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4435 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
4436 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
4437 'char' to 'int' can be omitted, if both operands are 'unsigned char';
4438 see feature request #877103
4439 * src/SDCCval.c: updated call of decorateType()
4440 (valBitwise): fixed bug #882876
4441 (valMinus): added promotion
4442 (valLogicAndOr): result is unsigned
4443 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
4444 * src/SDCCsymt.c (computeType),
4445 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
4446 must not cause an unsigned operation
4447 * src/pic/glue (pic14emitRegularMap),
4448 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
4450 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

4467 * src/pic/ralloc.h: applied patch from Slade Rich;
4468 added support for multiple code pages and multiple RAM banks on the
4469 PIC 14 port. The ASM files now no longer simply assume all the
4470 code / RAM are in the same page / bank. This means the linker can
4471 safely allocate code/RAM of separate ASM files to different pages/banks.
4472 * doc/sdccman.lyx: added Slade's tips
4473 * src/mcs51/peeph.def: fixed bug #880768

4482 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
4485 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
4486 strtof is not part of C89 and isn't included with Mac OS X.
4488 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4515 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
4517 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
4518 loaded with the linker search paths (-L arguments) and the libraries
4519 to be linked with the current source (-l arguments). Changes
4520 currently will affect only the pic16 port.
4521 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4522 include path the port specific paths and port specific libraries,
4523 * gplink command now contains the $3 argument,
4524 * src/pic16/device.h,
4525 * src/pic16/device.c,: structure PIC_device is made public and
4526 renamed to PIC16_device, the same for variable Pics which is renamed

4541 Documenting changes from previous commits.
4542 * configure.in (version 1.56),
4543 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4544 when generating output files to configure the pic16 library,
4545 but now I've commented it out, since gputils aren't installed in the
4546 SF compile farm, so library won't compile
4548 * device/lib/Makefile.in (version 1.56): initially I've added in
4549 target 'all' the prerequestive 'model-pic16' so it compiled the
4550 pic16 library, but now I've commented it out for the same reasons
4552 * added targets 'model-pic16' and 'objects-pic16' to compile the
4554 * added target 'port-specific-objects-pic16' to handle the
4555 generated libraries and copy them into the build/ directory
4556 * added target 'clean-intermediate-pic16' to clean intermediate
4557 files into pic16 directory
4558 * in target 'installdirs' added line to create directory pic16 in
4559 the installation path
4561 * device/include/Makefile.in (version 1.11): in target 'install'
4562 added lines to copy all header files to installation path,
4563 * in target 'installdirs' added line create directory for pic16
4564 headers in the installation path

4579 * src/z80/main.c (_parseOptions): fixed the portmode= command line
4580 option so that it actually works. Made it specific to the z80, since
4581 the gbz80 doesn't have these kinds of I/O ports.
4583 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4585 * device/include/z180.h,

4607 Mainly changes to support compilation of the device libraries
4608 * src/pic16/device.c: stack is allocated via symbol and not
4609 via literal number. The symbol is placed in the corresponding
4610 position of the data ram
4611 * (pic16_dump_section): relocatable and absolute uninitialized
4612 data are now emitted in sorted order to reduce section naming,
4613 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4614 weren't marked as being in the access bank,
4616 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4618 Added portion of GNU PIC Library under the directory
4619 device/include/pic16 and device/lib/pic16. These files
4620 contain the declarations of SFRs for the PIC18Fxx2 devices.
4621 The directory is initialized via configure from toplevel.
4623 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
4625 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

4651 all over. Telling LaTeX to be less strict with word spacing
4652 to better keep the right margin. Changed some notes about
4653 maintainance of the ports in section 3.2.1 - is it OK like this?
4655 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4695 * src/pic16/peeph.def: all peepholes with movff are commented out,
4696 because there is a problem in the pcode peep optimizer,
4697 * src/pic16/ralloc.c: the register allocator can now reuse local

4849 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4851 PIC16 port related changes:
4852 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4853 added variable stackPos,
4855 * gen.c: genCall, assignResultValue: added support for
4856 pushing/retrieving function parameters to/from stack,
4857 genFunction,genEndFunction: setup stack frame for the
4859 genAddrOf: will be changed according to bug 863624
4861 * added files genutils.c and genutils.h which contain gen*
4862 debugged and optimised functions extracted from gen.c
4864 * glue.c: added variable 'externs' which holds extern symbols,
4865 pic16emitRegularMap: is modified to properly handle relocatable
4866 symbols under the new scheme,
4867 pic16createInterruptVect: is modified
4868 pic16printPublics: is modified to emit 'global' assembler directives,
4869 added pic16_printExterns to print extern symbols,
4870 pic16glue: initializes stack/frame pointer in the beginning of
4871 the assembly output. Temporary hack, will be corrected later,
4872 because gplink yet does not support stack and SDCC does not
4873 yet support a type of crt0.o object to create the final binary.
4875 * Removed many lines that contain 8051 legacy code.
4876 * The code is finally placed under a 'code' directive.
4877 * Added port specific options.
4879 * _process_pragma: simplified since now we do not need *special*
4880 include file to define SFR registers. But a separate header
4881 will be needed. This will be developed later.
4882 * _pic16_parseOptions: added, parses port specific options:
4883 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4884 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4885 --preplace-udata-with=
4887 * _pic16_setDefaultOptions: modified to initialize section names,
4888 but hack is temporarly out of order since it needs improvement.
4889 * _pic16_genAssemblerPreamble: configuration words are emitted by
4890 their address instead of their name. This part is incomplete and
4891 supports only the 18Fxx2 devices. Other devices will emit an error
4892 during assembly since they do not contain the same set of config
4894 * _pic16_genIVT: is modified,
4896 * pcode.c: added definitions for some hardware registers that are needed
4898 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4899 All PCI entries are updated. Now LFSR is supported.
4900 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4901 * added pic16_newpCodeOpLit2 to support instructions with
4902 two literal arguments
4903 * pic16_pCode2str: corrected code that emits assembler instructions
4904 with two literal operands and those that have an access bit modifier
4905 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4906 this fixes a bug which caused some labels to be lost, when an
4907 assembler directive was added, i.e. banksel,
4908 * pic16_FixRegisterBanking: improved logic that causes the insertion
4910 * InlineFunction: functions that are called once, are not any more
4911 inlined. This can be a port option in the future,
4913 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4915 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4916 hold the corresponding uninitialized symbols,
4917 * pic16_allocProcessorRegister: registers have explicit marked the
4919 * pic16_allocInternalRegister: registers are explicit marked as
4921 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4922 processing list, so bit registers were lost,
4925 * ralloc.h: added field 'accessBank' and original symbol operand
4926 in register definition,
4927 * removed the field isMapped from register definition,
4929 ** Several functions have been removed from various sources:

4941 * support/scripts/inc2h.pl: changed definition of BIT_AT
4942 to emit 'sbit at' instead of 'bit at'. This was a request.
4944 PIC16 port related preliminary changes:
4945 * gen.c: prefixed function popRegFromString with
4946 pic16_ and all references to it corrected
4947 * pcode.c: all pic16_pc_* hardware registers prefixed
4948 with underscore (_),
4949 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4950 * ralloc.c: newReg(): when register is REG_SFR then
4951 set address to rIdx,
4952 pic16_allocProcessorRegister(): marks register wasUsed=0
4953 pic16_writeUsedRegs(): added a call to assign processor
4954 registers via pic16_assignFixedRegisters
4956 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4958 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4959 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4960 variables in unused register banks. Also the SSEG is placed
4961 wherever there is enough space for it, and IDATA can be anywhere
4962 in internal RAM. For now compile using -Wl-Y[stack_size].
4963 The mem file is different for this option as well, since it
4964 makes no sense of talking about DSEG lenght.
4966 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4968 * src/SDCClrange.c: fixed bug 869095 that caused segfault

5215 it breaks with bitfields, extern declarations, and gcse analysis.
5216 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5217 could be assigned through a pointer, so don't complain.

5974 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5975 fetching of the pointer
5976 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5977 copied from genNearPointerSet()
5978 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5979 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5993 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5995 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5996 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5997 type for bits was changed. It resulted in bit variables becoming
5998 global, which is not permitted in PIC 14 assembly output.
6000 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6002 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6015 A few small changes that speed up the peephole optimizer.
6019 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6021 Try to make the peephole optimizer smarter by maintaining
6022 an association between the assembly source code and the
6023 iCodes that originated them. Put this information to use
6024 with a new peephole rule condition "notVolatile" so that
6025 the rules can be aggressive yet still safe.
6030 * src/mcs51/peeph.def
6032 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6036 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6037 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6038 if the left or right operand symbols have the accuse flag set.
6040 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6042 Changed the type of the result of the ! (NOT) operator to char;
6043 previously it returned the same type as the source. This allows
6044 us to eliminate all the genFloatNot functions (all of its target
6045 implementations were very buggy) since !float can use the same
6048 * src/SDCCicode.c (ast2iCode): ! returns char

6057 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6058 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6059 during interrupts. Ensure WSAVE is located at a shared bank address.
6060 2. Fixed page selection in some places
6061 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6062 the registers name strings.
6063 4. Fixed "signed / unsigned compare" compiler warnings.
6064 5. The PIC port manages its own allocation of the general purpose
6065 registers, but makes no attempt to reuse them. As a result when
6066 compiling it soon runs out of general purpose registers. Some
6067 additional code was added to the files pcode.c and device.c to walk
6068 through the function call tree and rename the registers so that they
6078 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6085 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6087 Made bitfield a distinct type from bit so that bitfields
6088 convert as per ANSI C and bits retain their traditional
6089 boolean style behaviour. Implemented bitfield support in
6097 * src/ds390/gen.c: bit v bitfield split
6098 * src/z80/gen.c: New support for bitfields
6099 * support/regression/tests/bitfields.c: reenabled z80,
6102 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6104 Rules 246.x, 247.x relate to bitfields, the others speed up
6105 access to xdata mapped I/O devices.
6107 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6109 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6111 Cleaned up genPackBits and genUnpackBits and added two helper
6112 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6113 for literal assignments in genPackBits (thanks to Frieder for
6119 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6121 Fixed bug #748310 (pointer to function type mishandled when the
6122 function name is omitted). Also fixed a SIGSEGV when a function
6123 attribute (reentrant, etc) is used on a non-function or on a
6124 function but misplaced before the parameter list.
6126 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6128 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

6151 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6153 Made the constant following the "interrupt" keyword optional. If
6154 omitted, the function will not automatically be given an entry
6155 in the interrupt vector table (similar to #pragma NOIV, but
6156 less syntacticly kludgy). The interrupt number is also now
6157 range checked. Also fixed a bug in the high order bit example

6171 * src/SDCCicode.c (operandOperation): rewritten some ops
6172 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6173 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6175 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6176 be re-activated by defining REDUCE_LITERALS)
6177 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6178 unsigned, but are signed by default
6179 * src/SDCCval.c (constVal): rearranged
6180 * src/SDCCval.c (valMod): preliminary fix
6181 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6633 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
6634 the regression tests I'm not brave enough to enable 245.b, 245.c
6635 * doc/sdccman.lyx: added latex preamble for hyperref package.
6636 Using pdflatex this will give you a hyperlinked pdf file with
6637 bookmarks. (prepend '%' before /usepackage if this breaks something)

6675 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
6677 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
6678 it can be defined with CFLAGS when running configure
6679 * src/SDCCmain.c: fixed compiling + linking with object files
6681 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

6684 added --disable-pic16-port
6685 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
6686 * src/SDCCmain.c: linkOptions is changed to set *,
6687 added if/endif conditional macros to remove options help
6688 messages from optionsTable when a port is not configured, added
6689 support for the PIc16 port in the ports table, when executing
6690 the compiler with no port specified on command line, a default
6691 port is selected with the new macro DEFAULT_PORT which is
6692 defined in port.h, in setDefaultOptions() linkOptions is removed
6693 from initialization assignment, since now it is a set,
6694 parseCmdLine uses setParseWithComma for linkOptions, in
6695 linkEdit() linkOptions are accessed with new function indexSet()
6696 which returns the i'th item of a set variable. See SDCCset.c, in
6697 linkEdit() when calling buildCmdLine(), added linkOptions as
6698 last argument. Now users can pass arguments to gplink via the
6699 -Wl option, main() uses pic16glue() to glue up pic16 programs

6711 * src/pic16/glue.c: commented out some error producing lines
6712 * src/pic16/main.c: __config directives are commented out to stop
6713 gpasm complaining and test the linkage with gplink, _linkCmd and
6714 _asmCmd changed to be more gplink and gpasm friendly
6715 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6716 produced an error when parsed, peep rule 12 is added to utilize
6717 movff, but it is commented out since the pCode does not support
6718 yet a command with 2 address arguments
6720 2003-05-18 <johan AT balder>
6722 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6749 2003-05-11 Borut Razem <borut.razem AT siol.net>
6751 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6752 the path of bin directory, so that PATH is the only env. variable, which has to be set
6753 in case of standard installation.
6754 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7847 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7849 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7850 overlaying area for it (uses RegBankUsed[4]).
7852 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7853 bank zero as used by default. By default aslink locates the stack
7854 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7855 the creation of the .mem file. Delegates the allocation of data area
7856 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7857 the begining of the stack area to aslink.
7859 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7860 glue() in SDCCglue.c creates an area for it.
7862 2002-09-03 Borut Razem <borut.razem AT siol.net>
7863 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7864 sdcc/src/pic/glue.c:
7865 introduced atexit() handler for teporay files removal in case of
7866 errors, assertions, ...
7868 2002-08-29 Borut Razem <borut.razem AT siol.net>
7869 * sdcc/support/cpp2/auto-host_vc_in.h:
7870 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7871 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7872 Maybe there is a similar problem with BORLANDC? It should be checked!
7874 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7875 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7876 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7877 was not executed, and the compiler (cl) launched a warning:
7878 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7880 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7881 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7883 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7884 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7886 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7887 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7888 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7889 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7890 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7891 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7892 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7893 - added Release configuration in VS projects
7894 - review of compiler an linker options
7895 - VC .exe files are generated in bin_vc directory, not to interfere
7896 with binaries generated from other projects (cygwin, mingw, bcc ...)
7898 * sdcc/src/yacc.dsp: added
7900 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7901 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7902 and insert the version number definitions from .version
7904 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7906 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7907 added - genarate auto-host.h using auto-host_vc_in.h as template
7910 removed from CVS, generated automatically
7912 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7913 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7915 2002-08-11 Borut Razem <borut.razem AT siol.net>
7916 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7918 2002-08-10 Borut Razem <borut.razem AT siol.net>
7919 * src/SDCCmain.c (main):
7920 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7921 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7922 The consequence was that some temporary files were not removed.
7925 unification of code in functions tempfilename() and tempfile():
7926 function tempnam() is defined in Visual Studio 6.0 and .NET
7928 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7930 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7931 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7932 - removed compiler command line option /WX: Treats all warnings as errors
7933 - update a list of source files, included into the project
7935 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7936 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7937 changed project type to Generic Project so that can be correcly converted to VS.NET project
7939 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7941 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7943 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7945 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7946 added return 0 statements after assert() to make compiler happy
7948 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7949 added newline in the def file to keep MSC compiler satisfied
7951 * sdcc/src/z80/gen.c:
7952 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7953 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7954 - solved MSC error in function aopDump()
7956 * sdcc_vc.h: define PREFIX as "\\sdcc"
7958 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7959 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8007 Added -p option. Allows port dependent processor to be specified.
8010 Initialized the new field char *Processor field to NULL in all ports
8013 Compiler generated registers for interrupt context saving
8014 were not getting allocated.
8016 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8019 Fixed left shift. Will promote the left side of a left shift
8020 if a) left shifting more than size of operand or b) when assigned
8021 to something size > size of left side
8023 2002-03-14 Scott Dattalo <scott AT dattalo.com>

8133 * sdcc/src/SDCCloop.c:
8134 Previous fix was not good. basic blocks that have "break" or "return" are
8135 not really partof a loop , but live ranges used in these blocks should
8136 be live thru the entire loop, so set partOfLoop but don't add them to
8139 2002-02-21 <johan AT FRIJA>
8141 * src/SDCCcse.c: fixed bug #514308
8143 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

8149 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
8151 2002-02-10 Karl Bongers <karl AT turbobit.com>
