1484 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1485 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1486 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1487 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1488 always available in leading double underscore form. The C99 support is
1489 mostly missing, but it's a start.

1569 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1571 * device/lib/printf_large.c: removed inline assembly for portability and
1572 readability. Use printf_fast if speed or size are more important.
1573 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1574 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1576 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1578 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1579 prevent compiler warning
1581 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1583 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1584 moved to level 0 and declared as static. Also they are explicit
1585 placed in access bank. This was necessery because some times they
1586 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1587 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1588 optimizations. Currently only compare to unsigned char is implemented,
1589 * src/pic16/gen.c: added fReturnIdx array,
1590 * (struct resolvedIfx) is moved to gen.h and made public,
1591 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1592 * (aopForSym): added an optimization to directly store in stack of
1593 the operand of a SEND iCode,
1594 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1595 but as registers instead (AOP_REG) using the fReturnIdx array,
1596 * (pic16_freeAsmop): remove the freed register from the
1597 _G.sregsAlloc field,
1598 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1599 a compare of 'WREG',
1600 * (pic16_popGetTempRegCond): changed function prototype, now
1601 function takes also a bitVector argument v which holds the current
1602 set of registers that are allocated for stack access by aopForSym,
1603 registers allocated in aopForSym for accessing stack symbols are not
1604 any more part of the functions usedRegs field,
1605 * (genCall): some times aopOp is called for a stack variable to be
1606 send, aopForSym might perform the push, if this is true make sure
1607 that genCall doesn't push the variable twice by testing _G.resDirect,
1608 * (genFunction): changed testing for unspecified interrupt number
1609 from 256 to INTNO_UNSPEC,
1610 * modified selection scheme of frame pointer generation. Previously
1611 if function did use local registers a frame pointer was generated,
1612 now a frame pointer is generated only if function has arguments
1613 (that need PLUSW2 register access), or has stack arguments, or the
1614 compiler is not instructed to omit the frame pointer,
1615 * (genEndFunction): before restoring local registers that were saved
1616 in the function preamble, also restore the registers that *might*
1617 have been allocated for stack access,
1618 * (genRet): removed some old comments,
1619 * (genCmp, the active (RN's) version): added a call to the
1620 pic16_genCmp_special function to perform the compare with a more
1621 robust and optimized way,
1622 * (genInline): a feature has been added in inline code generation,
1623 which allows a wildcard variable substitution when writing inline
1624 assembly. Code is incomplete and experimental therefore undocumented,
1625 * (genCast): changed order of aopOp for result and right to allow
1626 aopForSym to directly load the result if possible,
1627 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1628 perform an optimized compare on some selected special occasions,
1629 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1630 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1631 generate an IVT any more,
1632 * src/pic16/main.c (pic16_optionsTable): added command line option
1634 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1635 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1637 * src/pic16/NOTES: Raphael Neider added in list of active developers
1638 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1639 jumptable_end to prevent bug #,
1640 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1641 inCond and outCond fields,
1642 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1643 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1644 turn off register spilling,
1645 * (packRegsForOneUse): synced with other ports' versions although it
1646 is not used currently,
1647 * (pic16_packRegisters): added an optimization while reading
1648 structure bitfields, some registers may be saved (malloc code is
1649 decreased by 80 bytes)
1651 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1653 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1654 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1655 this can be optimized more?
1657 2005-03-10 Raphael Neider <rneider AT web.de>
1659 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1660 genNearPointerGet): (hopefully) fixed access to bitfields via
1661 pointers (p->bitN = x; and x = p->bitN; failed)

1706 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1707 to keep the correct label reference count when adding/removing references
1708 to labels. A peephole file using this is appended to patch #1144962.

2295 Adding support for replacing ljmps with sjmps in jumptables
2296 generated for switch statements. For now you need to set the
2297 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2298 Now 4 algorithms for mcs51 jumptable generation are used:
2299 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2300 addresses loaded pc-relative for up to 112 cases and stack-pushing
2301 target addresses loaded with offset from dptr for up to 256 cases.

2331 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2333 * added libc directory. The current version of LibC contains string
2334 functions, ctype functions and macros and some functions of the
2335 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2336 be extensively tested in the future. Standard disclaimer here.
2337 Library is not automatically build yet. But one can build it by
2338 invoking 'make' inside the libc directory.

2349 * (pic16_storeForReturn): optimized return of 0,
2350 * (genCmp): experimental code for new genCmp which uses PIC18's
2351 special compare&skip instructions. Initial tests fail some times
2352 with variables grater than 1 byte in size, so new code is disabled,
2353 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2355 * (genCast): began a fix to optimize the casting of a bit to another
2356 bit, now assigning a bitfield to another bitfield will fail, sorry,

2370 registers when it shouldn't,
2371 * src/pic16/ralloc.c (allocReg): add preliminary support for
2372 supporting a limited set of temporary registers,
2374 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2380 (genFunction): optimize RECEIVE iCodes in reentrant functions
2382 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5265 virus/worm forged address usage.
5267 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
5269 Fixed promotion, it should be done on AST level:

5293 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
5295 * src/SDCCast.c: added an additional type flow in decorateType() of
5296 opposite direction, see feature request #860006; it's enabled at runtime
5297 by setting the environment variable SDCC_NEWTYPEFLOW
5298 * src/SDCCast.h: changed prototype of decorateType()
5299 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
5300 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
5301 'char' to 'int' can be omitted, if both operands are 'unsigned char';
5302 see feature request #877103
5303 * src/SDCCval.c: updated call of decorateType()
5304 (valBitwise): fixed bug #882876

5331 * src/pic/ralloc.h: applied patch from Slade Rich;
5332 added support for multiple code pages and multiple RAM banks on the
5333 PIC 14 port. The ASM files now no longer simply assume all the
5334 code / RAM are in the same page / bank. This means the linker can
5335 safely allocate code/RAM of separate ASM files to different pages/banks.
5336 * doc/sdccman.lyx: added Slade's tips
5337 * src/mcs51/peeph.def: fixed bug #880768

5379 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5381 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5382 loaded with the linker search paths (-L arguments) and the libraries
5383 to be linked with the current source (-l arguments). Changes
5384 currently will affect only the pic16 port.
5385 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5386 include path the port specific paths and port specific libraries,
5387 * gplink command now contains the $3 argument,
5388 * src/pic16/device.h,
5389 * src/pic16/device.c,: structure PIC_device is made public and
5390 renamed to PIC16_device, the same for variable Pics which is renamed

5405 Documenting changes from previous commits.
5406 * configure.in (version 1.56),
5407 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5408 when generating output files to configure the pic16 library,
5409 but now I've commented it out, since gputils aren't installed in the
5410 SF compile farm, so library won't compile
5412 * device/lib/Makefile.in (version 1.56): initially I've added in
5413 target 'all' the prerequestive 'model-pic16' so it compiled the
5414 pic16 library, but now I've commented it out for the same reasons
5416 * added targets 'model-pic16' and 'objects-pic16' to compile the
5418 * added target 'port-specific-objects-pic16' to handle the
5419 generated libraries and copy them into the build/ directory
5420 * added target 'clean-intermediate-pic16' to clean intermediate
5421 files into pic16 directory
5422 * in target 'installdirs' added line to create directory pic16 in
5423 the installation path
5425 * device/include/Makefile.in (version 1.11): in target 'install'
5426 added lines to copy all header files to installation path,
5427 * in target 'installdirs' added line create directory for pic16
5428 headers in the installation path

5443 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5444 option so that it actually works. Made it specific to the z80, since
5445 the gbz80 doesn't have these kinds of I/O ports.
5447 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5449 * device/include/z180.h,

5473 via literal number. The symbol is placed in the corresponding
5474 position of the data ram
5475 * (pic16_dump_section): relocatable and absolute uninitialized
5476 data are now emitted in sorted order to reduce section naming,
5477 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5478 weren't marked as being in the access bank,
5480 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5482 Added portion of GNU PIC Library under the directory
5483 device/include/pic16 and device/lib/pic16. These files
5484 contain the declarations of SFRs for the PIC18Fxx2 devices.
5485 The directory is initialized via configure from toplevel.

5515 all over. Telling LaTeX to be less strict with word spacing
5516 to better keep the right margin. Changed some notes about
5517 maintainance of the ports in section 3.2.1 - is it OK like this?

5713 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5715 PIC16 port related changes:
5716 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5717 added variable stackPos,
5719 * gen.c: genCall, assignResultValue: added support for
5720 pushing/retrieving function parameters to/from stack,
5721 genFunction,genEndFunction: setup stack frame for the
5723 genAddrOf: will be changed according to bug 863624
5725 * added files genutils.c and genutils.h which contain gen*
5726 debugged and optimised functions extracted from gen.c
5728 * glue.c: added variable 'externs' which holds extern symbols,
5729 pic16emitRegularMap: is modified to properly handle relocatable
5730 symbols under the new scheme,
5731 pic16createInterruptVect: is modified
5732 pic16printPublics: is modified to emit 'global' assembler directives,
5733 added pic16_printExterns to print extern symbols,
5734 pic16glue: initializes stack/frame pointer in the beginning of
5735 the assembly output. Temporary hack, will be corrected later,
5736 because gplink yet does not support stack and SDCC does not
5737 yet support a type of crt0.o object to create the final binary.
5739 * Removed many lines that contain 8051 legacy code.
5740 * The code is finally placed under a 'code' directive.
5741 * Added port specific options.
5743 * _process_pragma: simplified since now we do not need *special*
5744 include file to define SFR registers. But a separate header
5745 will be needed. This will be developed later.
5746 * _pic16_parseOptions: added, parses port specific options:
5747 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5748 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5749 --preplace-udata-with=
5751 * _pic16_setDefaultOptions: modified to initialize section names,
5752 but hack is temporarly out of order since it needs improvement.
5753 * _pic16_genAssemblerPreamble: configuration words are emitted by
5754 their address instead of their name. This part is incomplete and
5755 supports only the 18Fxx2 devices. Other devices will emit an error
5756 during assembly since they do not contain the same set of config
5758 * _pic16_genIVT: is modified,
5760 * pcode.c: added definitions for some hardware registers that are needed
5762 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5763 All PCI entries are updated. Now LFSR is supported.
5764 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5765 * added pic16_newpCodeOpLit2 to support instructions with
5766 two literal arguments
5767 * pic16_pCode2str: corrected code that emits assembler instructions
5768 with two literal operands and those that have an access bit modifier
5769 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5770 this fixes a bug which caused some labels to be lost, when an
5771 assembler directive was added, i.e. banksel,
5772 * pic16_FixRegisterBanking: improved logic that causes the insertion
5774 * InlineFunction: functions that are called once, are not any more
5775 inlined. This can be a port option in the future,
5777 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5779 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5780 hold the corresponding uninitialized symbols,
5781 * pic16_allocProcessorRegister: registers have explicit marked the
5783 * pic16_allocInternalRegister: registers are explicit marked as
5785 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5786 processing list, so bit registers were lost,
5789 * ralloc.h: added field 'accessBank' and original symbol operand
5790 in register definition,
5791 * removed the field isMapped from register definition,
5793 ** Several functions have been removed from various sources:
5794 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5795 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5796 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5797 pic16_assignRelocatableRegisters
5799 ** others have been introduced:
5800 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5801 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5803 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5805 * support/scripts/inc2h.pl: changed definition of BIT_AT
5806 to emit 'sbit at' instead of 'bit at'. This was a request.
5808 PIC16 port related preliminary changes:
5809 * gen.c: prefixed function popRegFromString with
5810 pic16_ and all references to it corrected
5811 * pcode.c: all pic16_pc_* hardware registers prefixed
5812 with underscore (_),
5813 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5814 * ralloc.c: newReg(): when register is REG_SFR then
5815 set address to rIdx,
5816 pic16_allocProcessorRegister(): marks register wasUsed=0
5817 pic16_writeUsedRegs(): added a call to assign processor
5818 registers via pic16_assignFixedRegisters
5820 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5822 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5823 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5824 variables in unused register banks. Also the SSEG is placed
5825 wherever there is enough space for it, and IDATA can be anywhere
5826 in internal RAM. For now compile using -Wl-Y[stack_size].
5827 The mem file is different for this option as well, since it
5828 makes no sense of talking about DSEG lenght.
5830 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5832 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5833 in certain cases, e.g. when ROM assignment, patch provided
5834 from Albert den Haan.

6077 * src/SDCCast.c (decorateType): disabled a transformation I added in
6078 revision 1.188 (access to fields of a structure at an absolute address);
6079 it breaks with bitfields, extern declarations, and gcse analysis.
6080 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6081 could be assigned through a pointer, so don't complain.

6186 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
6187 uninitialized variables) for the mcs51. Set environment variable

6189 xdata initialization slightly shorter
6191 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6838 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6839 fetching of the pointer
6840 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6841 copied from genNearPointerSet()
6842 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6843 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6859 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6860 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6861 type for bits was changed. It resulted in bit variables becoming
6862 global, which is not permitted in PIC 14 assembly output.
6864 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6866 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6879 A few small changes that speed up the peephole optimizer.
6883 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6885 Try to make the peephole optimizer smarter by maintaining
6886 an association between the assembly source code and the
6887 iCodes that originated them. Put this information to use
6888 with a new peephole rule condition "notVolatile" so that
6889 the rules can be aggressive yet still safe.
6894 * src/mcs51/peeph.def
6896 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6900 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6901 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6902 if the left or right operand symbols have the accuse flag set.
6904 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6906 Changed the type of the result of the ! (NOT) operator to char;
6907 previously it returned the same type as the source. This allows
6908 us to eliminate all the genFloatNot functions (all of its target
6909 implementations were very buggy) since !float can use the same
6912 * src/SDCCicode.c (ast2iCode): ! returns char

6921 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6922 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6923 during interrupts. Ensure WSAVE is located at a shared bank address.
6924 2. Fixed page selection in some places
6925 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6926 the registers name strings.
6927 4. Fixed "signed / unsigned compare" compiler warnings.
6928 5. The PIC port manages its own allocation of the general purpose
6929 registers, but makes no attempt to reuse them. As a result when
6930 compiling it soon runs out of general purpose registers. Some
6931 additional code was added to the files pcode.c and device.c to walk
6932 through the function call tree and rename the registers so that they
6942 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6943 genPlus() & genMinus() when the result is the same as left or right

6949 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6951 Made bitfield a distinct type from bit so that bitfields
6952 convert as per ANSI C and bits retain their traditional
6953 boolean style behaviour. Implemented bitfield support in
6961 * src/ds390/gen.c: bit v bitfield split
6962 * src/z80/gen.c: New support for bitfields
6963 * support/regression/tests/bitfields.c: reenabled z80,
6966 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6968 Rules 246.x, 247.x relate to bitfields, the others speed up
6969 access to xdata mapped I/O devices.
6971 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6973 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6975 Cleaned up genPackBits and genUnpackBits and added two helper
6976 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6977 for literal assignments in genPackBits (thanks to Frieder for
6983 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6985 Fixed bug #748310 (pointer to function type mishandled when the
6986 function name is omitted). Also fixed a SIGSEGV when a function
6987 attribute (reentrant, etc) is used on a non-function or on a
6988 function but misplaced before the parameter list.
6990 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6992 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6993 * support/Util/SDCCerr.h,

7015 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7017 Made the constant following the "interrupt" keyword optional. If
7018 omitted, the function will not automatically be given an entry
7019 in the interrupt vector table (similar to #pragma NOIV, but
7020 less syntacticly kludgy). The interrupt number is also now
7021 range checked. Also fixed a bug in the high order bit example

7029 * support/Util/SDCCerr.h
7032 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7035 * src/SDCCicode.c (operandOperation): rewritten some ops
7036 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7037 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7039 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7040 be re-activated by defining REDUCE_LITERALS)
7041 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7042 unsigned, but are signed by default
7043 * src/SDCCval.c (constVal): rearranged
7044 * src/SDCCval.c (valMod): preliminary fix
7045 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7550 * src/SDCCmain.c: linkOptions is changed to set *,
7551 added if/endif conditional macros to remove options help
7552 messages from optionsTable when a port is not configured, added
7553 support for the PIc16 port in the ports table, when executing
7554 the compiler with no port specified on command line, a default
7555 port is selected with the new macro DEFAULT_PORT which is
7556 defined in port.h, in setDefaultOptions() linkOptions is removed
7557 from initialization assignment, since now it is a set,
7558 parseCmdLine uses setParseWithComma for linkOptions, in
7559 linkEdit() linkOptions are accessed with new function indexSet()
7560 which returns the i'th item of a set variable. See SDCCset.c, in
7561 linkEdit() when calling buildCmdLine(), added linkOptions as
7562 last argument. Now users can pass arguments to gplink via the
7563 -Wl option, main() uses pic16glue() to glue up pic16 programs

7575 * src/pic16/glue.c: commented out some error producing lines
7576 * src/pic16/main.c: __config directives are commented out to stop
7577 gpasm complaining and test the linkage with gplink, _linkCmd and
7578 _asmCmd changed to be more gplink and gpasm friendly
7579 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7580 produced an error when parsed, peep rule 12 is added to utilize
7581 movff, but it is commented out since the pCode does not support
7582 yet a command with 2 address arguments
7584 2003-05-18 <johan AT balder>
7586 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7613 2003-05-11 Borut Razem <borut.razem AT siol.net>
7615 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7616 the path of bin directory, so that PATH is the only env. variable, which has to be set
7617 in case of standard installation.
7618 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8670 * SDCClrange.h: exposed setFromRange() and setToRange()
8671 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8672 packRegsForAccUse() (bug 542397)
8673 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8674 multiple times and emitting the fetch operations more than once
8675 added aopGetUsesAcc() function to allow binary operators to
8676 fetch their operands in the correct order; made genMinus() emit
8677 compact code for X = LITERAL - Y
8679 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8680 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8681 sprintf() in line 1267.
8683 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8684 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8687 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8688 Changes to aslink (All the changes are marked with 'JCF'):
8690 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8693 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8694 area BSEG. Also moves, if possible, the DATA area down into the internal
8695 ram so more space is available.
8697 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8700 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8701 not bytes. Function summary() which creates a memory usage summary
8702 file with extension .mem. Reports of overlaping stack and small stack
8703 size. If the space for the stack is less than 16 bytes aslink trows a
8706 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8707 the 8051. Option 'y' for memory summary output file.
8709 Changes to sdcc (All the changes are marked with 'JCF'):
8711 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8713 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8714 overlaying area for it (uses RegBankUsed[4]).
8716 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8717 bank zero as used by default. By default aslink locates the stack
8718 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8719 the creation of the .mem file. Delegates the allocation of data area
8720 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8721 the begining of the stack area to aslink.
8723 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8724 glue() in SDCCglue.c creates an area for it.
8726 2002-09-03 Borut Razem <borut.razem AT siol.net>
8727 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8728 sdcc/src/pic/glue.c:
8729 introduced atexit() handler for teporay files removal in case of
8730 errors, assertions, ...
8732 2002-08-29 Borut Razem <borut.razem AT siol.net>
8733 * sdcc/support/cpp2/auto-host_vc_in.h:
8734 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8735 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8736 Maybe there is a similar problem with BORLANDC? It should be checked!
8738 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8739 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8740 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8741 was not executed, and the compiler (cl) launched a warning:
8742 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8744 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8745 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8747 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8748 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8750 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8751 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8752 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8753 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8754 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8755 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8756 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8757 - added Release configuration in VS projects
8758 - review of compiler an linker options
8759 - VC .exe files are generated in bin_vc directory, not to interfere
8760 with binaries generated from other projects (cygwin, mingw, bcc ...)
8762 * sdcc/src/yacc.dsp: added
8764 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8765 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8766 and insert the version number definitions from .version
8768 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8770 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8771 added - genarate auto-host.h using auto-host_vc_in.h as template
8774 removed from CVS, generated automatically
8776 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8777 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8779 2002-08-11 Borut Razem <borut.razem AT siol.net>
8780 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8782 2002-08-10 Borut Razem <borut.razem AT siol.net>
8783 * src/SDCCmain.c (main):
8784 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8785 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8786 The consequence was that some temporary files were not removed.
8789 unification of code in functions tempfilename() and tempfile():
8790 function tempnam() is defined in Visual Studio 6.0 and .NET
8792 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8794 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8795 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8796 - removed compiler command line option /WX: Treats all warnings as errors
8797 - update a list of source files, included into the project
8799 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8800 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8801 changed project type to Generic Project so that can be correcly converted to VS.NET project
8803 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8805 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8807 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8809 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8810 added return 0 statements after assert() to make compiler happy
8812 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8813 added newline in the def file to keep MSC compiler satisfied
8815 * sdcc/src/z80/gen.c:
8816 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8817 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8818 - solved MSC error in function aopDump()
8820 * sdcc_vc.h: define PREFIX as "\\sdcc"
8822 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8823 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8825 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8826 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8827 - Rewrote the register banking algorithm.
8828 - Added pCode live-range analysis to registers (for now, only non-used and
8829 singly-used registers optimized away)
8831 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8833 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

8862 2002-03-28 Johan Knol <johan AT balder>
8864 * src/SDCCval.c: fixed bug #532436
8866 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8868 Added "char *Processor" field to the port structure.
8871 Added -p option. Allows port dependent processor to be specified.
8874 Initialized the new field char *Processor field to NULL in all ports
8877 Compiler generated registers for interrupt context saving
8878 were not getting allocated.
8880 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8883 Fixed left shift. Will promote the left side of a left shift
8884 if a) left shifting more than size of operand or b) when assigned
8885 to something size > size of left side
8887 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8889 tons of changes. Register allocation has been
8890 rewritten. Added customization for the various PICs. Flow

8995 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8997 * sdcc/src/SDCCloop.c:
8998 Previous fix was not good. basic blocks that have "break" or "return" are
8999 not really partof a loop , but live ranges used in these blocks should
9000 be live thru the entire loop, so set partOfLoop but don't add them to
9003 2002-02-21 <johan AT FRIJA>
9005 * src/SDCCcse.c: fixed bug #514308
9007 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9010 Fixed BUG #519583. If a conditional block ended in a return/break
9011 statement inside a loop, it was not being considered part of the loop.
9013 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9015 2002-02-10 Karl Bongers <karl AT turbobit.com>
9018 Fixed up SDCDB debugger somewhat. Updated debugger/README
9019 with lots of comments and notes.
9021 * device/examples/test2.c:
9022 Fix bug, "red" variable not being initialized(compiler complained).
9024 * device/examples/Makefile, examples/test3.c:

9026 for use as a multiple module SDCDB test case.
9028 * sim/ucsim/cmd.src/cmdset.cc:
9029 Took out debug printfs in ucsim "next" command.
9032 Karl and Johan start ucsim XA support. Most dissassembly working,
9033 about 75% emulation done(plenty of work remaining).
9035 * sim/ucsim/z80.src:
9036 Add Z80 support to ucsim, add test-ucz80 regression test,
9037 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

9073 set preprocessor defines (depending on options)
9075 * src/SDCCicode.c, src/SDCCicode.h:
9076 changes made to handle multiple sends & receives
9079 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
