1501 * src/SDCCglobal.h (struct options),
1503 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1504 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1505 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1506 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1507 always available in leading double underscore form. The C99 support is
1508 mostly missing, but it's a start.
1509 * support/regression/tests/bug-227710.c: fixed nonconforming use of

1588 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1590 * device/lib/printf_large.c: removed inline assembly for portability and
1591 readability. Use printf_fast if speed or size are more important.
1592 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1593 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1595 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1597 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1598 prevent compiler warning
1600 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1602 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1603 moved to level 0 and declared as static. Also they are explicit
1604 placed in access bank. This was necessery because some times they
1605 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1606 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1607 optimizations. Currently only compare to unsigned char is implemented,
1608 * src/pic16/gen.c: added fReturnIdx array,
1609 * (struct resolvedIfx) is moved to gen.h and made public,
1610 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1611 * (aopForSym): added an optimization to directly store in stack of
1612 the operand of a SEND iCode,
1613 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1614 but as registers instead (AOP_REG) using the fReturnIdx array,
1615 * (pic16_freeAsmop): remove the freed register from the
1616 _G.sregsAlloc field,
1617 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1618 a compare of 'WREG',
1619 * (pic16_popGetTempRegCond): changed function prototype, now
1620 function takes also a bitVector argument v which holds the current
1621 set of registers that are allocated for stack access by aopForSym,
1622 registers allocated in aopForSym for accessing stack symbols are not
1623 any more part of the functions usedRegs field,
1624 * (genCall): some times aopOp is called for a stack variable to be
1625 send, aopForSym might perform the push, if this is true make sure
1626 that genCall doesn't push the variable twice by testing _G.resDirect,
1627 * (genFunction): changed testing for unspecified interrupt number
1628 from 256 to INTNO_UNSPEC,
1629 * modified selection scheme of frame pointer generation. Previously
1630 if function did use local registers a frame pointer was generated,
1631 now a frame pointer is generated only if function has arguments
1632 (that need PLUSW2 register access), or has stack arguments, or the
1633 compiler is not instructed to omit the frame pointer,
1634 * (genEndFunction): before restoring local registers that were saved
1635 in the function preamble, also restore the registers that *might*
1636 have been allocated for stack access,
1637 * (genRet): removed some old comments,
1638 * (genCmp, the active (RN's) version): added a call to the
1639 pic16_genCmp_special function to perform the compare with a more
1640 robust and optimized way,
1641 * (genInline): a feature has been added in inline code generation,
1642 which allows a wildcard variable substitution when writing inline
1643 assembly. Code is incomplete and experimental therefore undocumented,
1644 * (genCast): changed order of aopOp for result and right to allow
1645 aopForSym to directly load the result if possible,
1646 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1647 perform an optimized compare on some selected special occasions,
1648 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1649 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1650 generate an IVT any more,
1651 * src/pic16/main.c (pic16_optionsTable): added command line option
1653 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1654 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1656 * src/pic16/NOTES: Raphael Neider added in list of active developers
1657 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1658 jumptable_end to prevent bug #,
1659 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1660 inCond and outCond fields,
1661 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1662 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1663 turn off register spilling,
1664 * (packRegsForOneUse): synced with other ports' versions although it
1665 is not used currently,
1666 * (pic16_packRegisters): added an optimization while reading
1667 structure bitfields, some registers may be saved (malloc code is
1668 decreased by 80 bytes)
1670 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1672 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1673 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1674 this can be optimized more?
1676 2005-03-10 Raphael Neider <rneider AT web.de>
1678 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1679 genNearPointerGet): (hopefully) fixed access to bitfields via
1680 pointers (p->bitN = x; and x = p->bitN; failed)
1682 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1725 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1726 to keep the correct label reference count when adding/removing references
1727 to labels. A peephole file using this is appended to patch #1144962.
1729 2005-02-14 Raphael Neider <rneider AT web.de>

2314 Adding support for replacing ljmps with sjmps in jumptables
2315 generated for switch statements. For now you need to set the
2316 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2317 Now 4 algorithms for mcs51 jumptable generation are used:
2318 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2319 addresses loaded pc-relative for up to 112 cases and stack-pushing
2320 target addresses loaded with offset from dptr for up to 256 cases.

2350 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2352 * added libc directory. The current version of LibC contains string
2353 functions, ctype functions and macros and some functions of the
2354 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2355 be extensively tested in the future. Standard disclaimer here.
2356 Library is not automatically build yet. But one can build it by
2357 invoking 'make' inside the libc directory.

2368 * (pic16_storeForReturn): optimized return of 0,
2369 * (genCmp): experimental code for new genCmp which uses PIC18's
2370 special compare&skip instructions. Initial tests fail some times
2371 with variables grater than 1 byte in size, so new code is disabled,
2372 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2374 * (genCast): began a fix to optimize the casting of a bit to another
2375 bit, now assigning a bitfield to another bitfield will fail, sorry,
2376 * src/pic16/main.c: disabled the use of lr-support feature,
2377 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2384 and 1 for banking instruction,
2385 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2386 caused stop processing pCodes after a inline assembly block,
2387 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2388 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2389 registers when it shouldn't,
2390 * src/pic16/ralloc.c (allocReg): add preliminary support for
2391 supporting a limited set of temporary registers,
2393 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2395 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2396 genDataPointerSet): ensure assignments always copy in MSB to LSB
2398 (loadRegFromAop): recognize CLRH optimization,
2399 (genFunction): optimize RECEIVE iCodes in reentrant functions
2401 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2403 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5312 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
5314 * src/SDCCast.c: added an additional type flow in decorateType() of
5315 opposite direction, see feature request #860006; it's enabled at runtime
5316 by setting the environment variable SDCC_NEWTYPEFLOW
5317 * src/SDCCast.h: changed prototype of decorateType()
5318 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()

5400 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5401 loaded with the linker search paths (-L arguments) and the libraries
5402 to be linked with the current source (-l arguments). Changes
5403 currently will affect only the pic16 port.
5404 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5405 include path the port specific paths and port specific libraries,
5406 * gplink command now contains the $3 argument,
5407 * src/pic16/device.h,
5408 * src/pic16/device.c,: structure PIC_device is made public and
5409 renamed to PIC16_device, the same for variable Pics which is renamed

5424 Documenting changes from previous commits.
5425 * configure.in (version 1.56),
5426 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5427 when generating output files to configure the pic16 library,
5428 but now I've commented it out, since gputils aren't installed in the
5429 SF compile farm, so library won't compile
5431 * device/lib/Makefile.in (version 1.56): initially I've added in
5432 target 'all' the prerequestive 'model-pic16' so it compiled the
5433 pic16 library, but now I've commented it out for the same reasons
5435 * added targets 'model-pic16' and 'objects-pic16' to compile the
5437 * added target 'port-specific-objects-pic16' to handle the
5438 generated libraries and copy them into the build/ directory
5439 * added target 'clean-intermediate-pic16' to clean intermediate
5440 files into pic16 directory
5441 * in target 'installdirs' added line to create directory pic16 in

5463 option so that it actually works. Made it specific to the z80, since
5464 the gbz80 doesn't have these kinds of I/O ports.
5466 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5468 * device/include/z180.h,

5745 debugged and optimised functions extracted from gen.c
5747 * glue.c: added variable 'externs' which holds extern symbols,
5748 pic16emitRegularMap: is modified to properly handle relocatable
5749 symbols under the new scheme,
5750 pic16createInterruptVect: is modified
5751 pic16printPublics: is modified to emit 'global' assembler directives,
5752 added pic16_printExterns to print extern symbols,
5753 pic16glue: initializes stack/frame pointer in the beginning of
5754 the assembly output. Temporary hack, will be corrected later,
5755 because gplink yet does not support stack and SDCC does not
5756 yet support a type of crt0.o object to create the final binary.
5758 * Removed many lines that contain 8051 legacy code.
5759 * The code is finally placed under a 'code' directive.
5760 * Added port specific options.
5762 * _process_pragma: simplified since now we do not need *special*
5763 include file to define SFR registers. But a separate header
5764 will be needed. This will be developed later.
5765 * _pic16_parseOptions: added, parses port specific options:
5766 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5767 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5768 --preplace-udata-with=
5770 * _pic16_setDefaultOptions: modified to initialize section names,
5771 but hack is temporarly out of order since it needs improvement.
5772 * _pic16_genAssemblerPreamble: configuration words are emitted by
5773 their address instead of their name. This part is incomplete and
5774 supports only the 18Fxx2 devices. Other devices will emit an error
5775 during assembly since they do not contain the same set of config
5777 * _pic16_genIVT: is modified,
5779 * pcode.c: added definitions for some hardware registers that are needed
5781 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5782 All PCI entries are updated. Now LFSR is supported.
5783 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5784 * added pic16_newpCodeOpLit2 to support instructions with
5785 two literal arguments
5786 * pic16_pCode2str: corrected code that emits assembler instructions
5787 with two literal operands and those that have an access bit modifier
5788 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5789 this fixes a bug which caused some labels to be lost, when an
5790 assembler directive was added, i.e. banksel,
5791 * pic16_FixRegisterBanking: improved logic that causes the insertion
5793 * InlineFunction: functions that are called once, are not any more
5794 inlined. This can be a port option in the future,
5796 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5798 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5799 hold the corresponding uninitialized symbols,
5800 * pic16_allocProcessorRegister: registers have explicit marked the
5802 * pic16_allocInternalRegister: registers are explicit marked as
5804 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5805 processing list, so bit registers were lost,
5808 * ralloc.h: added field 'accessBank' and original symbol operand
5809 in register definition,
5810 * removed the field isMapped from register definition,
5812 ** Several functions have been removed from various sources:
5813 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5814 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5815 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5816 pic16_assignRelocatableRegisters
5818 ** others have been introduced:
5819 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5820 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5822 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5824 * support/scripts/inc2h.pl: changed definition of BIT_AT
5825 to emit 'sbit at' instead of 'bit at'. This was a request.
5827 PIC16 port related preliminary changes:
5828 * gen.c: prefixed function popRegFromString with
5829 pic16_ and all references to it corrected
5830 * pcode.c: all pic16_pc_* hardware registers prefixed
5831 with underscore (_),
5832 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5833 * ralloc.c: newReg(): when register is REG_SFR then
5834 set address to rIdx,
5835 pic16_allocProcessorRegister(): marks register wasUsed=0
5836 pic16_writeUsedRegs(): added a call to assign processor
5837 registers via pic16_assignFixedRegisters
5839 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5841 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5842 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5843 variables in unused register banks. Also the SSEG is placed
5844 wherever there is enough space for it, and IDATA can be anywhere
5845 in internal RAM. For now compile using -Wl-Y[stack_size].
5846 The mem file is different for this option as well, since it
5847 makes no sense of talking about DSEG lenght.
5849 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5851 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5852 in certain cases, e.g. when ROM assignment, patch provided
5853 from Albert den Haan.

6094 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6096 * src/SDCCast.c (decorateType): disabled a transformation I added in
6097 revision 1.188 (access to fields of a structure at an absolute address);
6098 it breaks with bitfields, extern declarations, and gcse analysis.
6099 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6100 could be assigned through a pointer, so don't complain.
6101 * src/SDCCast.c (astErrors),
6103 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

6203 2003-11-13 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6205 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
6206 uninitialized variables) for the mcs51. Set environment variable

6857 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6858 fetching of the pointer
6859 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6860 copied from genNearPointerSet()
6861 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6862 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6878 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6879 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6880 type for bits was changed. It resulted in bit variables becoming
6881 global, which is not permitted in PIC 14 assembly output.
6883 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6885 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6898 A few small changes that speed up the peephole optimizer.
6902 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6904 Try to make the peephole optimizer smarter by maintaining
6905 an association between the assembly source code and the
6906 iCodes that originated them. Put this information to use
6907 with a new peephole rule condition "notVolatile" so that
6908 the rules can be aggressive yet still safe.
6913 * src/mcs51/peeph.def
6915 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6919 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6920 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6921 if the left or right operand symbols have the accuse flag set.
6923 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6925 Changed the type of the result of the ! (NOT) operator to char;
6926 previously it returned the same type as the source. This allows
6927 us to eliminate all the genFloatNot functions (all of its target
6928 implementations were very buggy) since !float can use the same
6931 * src/SDCCicode.c (ast2iCode): ! returns char

6940 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6941 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6942 during interrupts. Ensure WSAVE is located at a shared bank address.
6943 2. Fixed page selection in some places
6944 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6945 the registers name strings.
6946 4. Fixed "signed / unsigned compare" compiler warnings.
6947 5. The PIC port manages its own allocation of the general purpose
6948 registers, but makes no attempt to reuse them. As a result when
6949 compiling it soon runs out of general purpose registers. Some
6950 additional code was added to the files pcode.c and device.c to walk
6951 through the function call tree and rename the registers so that they
6961 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6962 genPlus() & genMinus() when the result is the same as left or right

6968 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6970 Made bitfield a distinct type from bit so that bitfields
6971 convert as per ANSI C and bits retain their traditional
6972 boolean style behaviour. Implemented bitfield support in
6980 * src/ds390/gen.c: bit v bitfield split
6981 * src/z80/gen.c: New support for bitfields
6982 * support/regression/tests/bitfields.c: reenabled z80,
6985 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6987 Rules 246.x, 247.x relate to bitfields, the others speed up
6988 access to xdata mapped I/O devices.
6990 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6992 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6994 Cleaned up genPackBits and genUnpackBits and added two helper
6995 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6996 for literal assignments in genPackBits (thanks to Frieder for
7002 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7004 Fixed bug #748310 (pointer to function type mishandled when the
7005 function name is omitted). Also fixed a SIGSEGV when a function
7006 attribute (reentrant, etc) is used on a non-function or on a
7007 function but misplaced before the parameter list.
7009 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7011 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7012 * support/Util/SDCCerr.h,
7013 * support/Util/SDCCerr.c: Added func attr misuse error msg

7034 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7036 Made the constant following the "interrupt" keyword optional. If
7037 omitted, the function will not automatically be given an entry
7038 in the interrupt vector table (similar to #pragma NOIV, but
7039 less syntacticly kludgy). The interrupt number is also now
7040 range checked. Also fixed a bug in the high order bit example

7048 * support/Util/SDCCerr.h
7051 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
7053 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
7054 * src/SDCCicode.c (operandOperation): rewritten some ops
7055 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7056 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7058 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7059 be re-activated by defining REDUCE_LITERALS)
7060 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7061 unsigned, but are signed by default
7062 * src/SDCCval.c (constVal): rearranged
7063 * src/SDCCval.c (valMod): preliminary fix
7064 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7106 constants are unsigned; added recognition of "u" flag for unsigned
7107 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7108 * src/SDCCval.c (valDiv, valMod): fixed signdness
7109 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7110 signedness of modulo, left and right shift

7569 * src/SDCCmain.c: linkOptions is changed to set *,
7570 added if/endif conditional macros to remove options help
7571 messages from optionsTable when a port is not configured, added
7572 support for the PIc16 port in the ports table, when executing
7573 the compiler with no port specified on command line, a default
7574 port is selected with the new macro DEFAULT_PORT which is
7575 defined in port.h, in setDefaultOptions() linkOptions is removed
7576 from initialization assignment, since now it is a set,
7577 parseCmdLine uses setParseWithComma for linkOptions, in
7578 linkEdit() linkOptions are accessed with new function indexSet()
7579 which returns the i'th item of a set variable. See SDCCset.c, in
7580 linkEdit() when calling buildCmdLine(), added linkOptions as
7581 last argument. Now users can pass arguments to gplink via the
7582 -Wl option, main() uses pic16glue() to glue up pic16 programs

7594 * src/pic16/glue.c: commented out some error producing lines
7595 * src/pic16/main.c: __config directives are commented out to stop
7596 gpasm complaining and test the linkage with gplink, _linkCmd and
7597 _asmCmd changed to be more gplink and gpasm friendly
7598 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7599 produced an error when parsed, peep rule 12 is added to utilize
7600 movff, but it is commented out since the pCode does not support
7601 yet a command with 2 address arguments
7603 2003-05-18 <johan AT balder>
7605 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7632 2003-05-11 Borut Razem <borut.razem AT siol.net>
7634 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7635 the path of bin directory, so that PATH is the only env. variable, which has to be set
7636 in case of standard installation.
7637 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8664 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8666 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8668 * in \sdcc\as\mcs51\ changed these files in order to create an
8669 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8670 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8671 following files to include the previous two files: aslink.dsp,
8672 Makefile.aslink, Makefile.bcc, and Makefile.in.
8674 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8675 .adb instead of .cdb
8677 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8679 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8680 value from option --iram-size.
8682 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8684 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8687 2002-09-18 <wiml AT hhhh.org>
8689 * SDCClrange.h: exposed setFromRange() and setToRange()
8690 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8691 packRegsForAccUse() (bug 542397)
8692 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8693 multiple times and emitting the fetch operations more than once
8694 added aopGetUsesAcc() function to allow binary operators to
8695 fetch their operands in the correct order; made genMinus() emit
8696 compact code for X = LITERAL - Y
8698 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8699 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8700 sprintf() in line 1267.
8702 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8703 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8706 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8707 Changes to aslink (All the changes are marked with 'JCF'):
8709 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8712 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8713 area BSEG. Also moves, if possible, the DATA area down into the internal
8714 ram so more space is available.
8716 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8719 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8720 not bytes. Function summary() which creates a memory usage summary
8721 file with extension .mem. Reports of overlaping stack and small stack
8722 size. If the space for the stack is less than 16 bytes aslink trows a
8725 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8726 the 8051. Option 'y' for memory summary output file.
8728 Changes to sdcc (All the changes are marked with 'JCF'):
8730 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8732 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8733 overlaying area for it (uses RegBankUsed[4]).
8735 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8736 bank zero as used by default. By default aslink locates the stack
8737 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8738 the creation of the .mem file. Delegates the allocation of data area
8739 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8740 the begining of the stack area to aslink.
8742 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8743 glue() in SDCCglue.c creates an area for it.
8745 2002-09-03 Borut Razem <borut.razem AT siol.net>
8746 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8747 sdcc/src/pic/glue.c:
8748 introduced atexit() handler for teporay files removal in case of
8749 errors, assertions, ...
8751 2002-08-29 Borut Razem <borut.razem AT siol.net>
8752 * sdcc/support/cpp2/auto-host_vc_in.h:
8753 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8754 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8755 Maybe there is a similar problem with BORLANDC? It should be checked!
8757 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8758 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8759 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8760 was not executed, and the compiler (cl) launched a warning:
8761 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8763 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8764 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8766 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8767 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8769 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8770 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8771 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8772 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8773 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8774 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8775 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8776 - added Release configuration in VS projects
8777 - review of compiler an linker options
8778 - VC .exe files are generated in bin_vc directory, not to interfere
8779 with binaries generated from other projects (cygwin, mingw, bcc ...)
8781 * sdcc/src/yacc.dsp: added
8783 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8784 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8785 and insert the version number definitions from .version
8787 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8789 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8790 added - genarate auto-host.h using auto-host_vc_in.h as template
8793 removed from CVS, generated automatically
8795 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8796 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8798 2002-08-11 Borut Razem <borut.razem AT siol.net>
8799 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8801 2002-08-10 Borut Razem <borut.razem AT siol.net>
8802 * src/SDCCmain.c (main):
8803 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8804 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8805 The consequence was that some temporary files were not removed.
8808 unification of code in functions tempfilename() and tempfile():
8809 function tempnam() is defined in Visual Studio 6.0 and .NET
8811 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8813 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8814 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8815 - removed compiler command line option /WX: Treats all warnings as errors
8816 - update a list of source files, included into the project
8818 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8819 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8820 changed project type to Generic Project so that can be correcly converted to VS.NET project
8822 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8824 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8826 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8828 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8829 added return 0 statements after assert() to make compiler happy
8831 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8832 added newline in the def file to keep MSC compiler satisfied
8834 * sdcc/src/z80/gen.c:
8835 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8836 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8837 - solved MSC error in function aopDump()
8839 * sdcc_vc.h: define PREFIX as "\\sdcc"
8841 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8842 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8844 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8845 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8846 - Rewrote the register banking algorithm.
8847 - Added pCode live-range analysis to registers (for now, only non-used and
8848 singly-used registers optimized away)
8850 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8852 * 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.
8854 2002-05-10 Scott Dattalo <scott AT dattalo.com>
8855 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

8877 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
8879 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
8881 2002-03-28 Johan Knol <johan AT balder>
8883 * src/SDCCval.c: fixed bug #532436
8885 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8887 Added "char *Processor" field to the port structure.
8890 Added -p option. Allows port dependent processor to be specified.
8893 Initialized the new field char *Processor field to NULL in all ports
8896 Compiler generated registers for interrupt context saving
8897 were not getting allocated.
8899 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8902 Fixed left shift. Will promote the left side of a left shift
8903 if a) left shifting more than size of operand or b) when assigned
8904 to something size > size of left side
8906 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8908 tons of changes. Register allocation has been
8909 rewritten. Added customization for the various PICs. Flow
8910 analysis is restructured. ...
8916 Added. device.c is a PIC port hack to accomodate variations
8919 2002-03-13 Michael Hope <michaelh AT vroom>
8921 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

9014 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9016 * sdcc/src/SDCCloop.c:
9017 Previous fix was not good. basic blocks that have "break" or "return" are
9018 not really partof a loop , but live ranges used in these blocks should
9019 be live thru the entire loop, so set partOfLoop but don't add them to
9022 2002-02-21 <johan AT FRIJA>
9024 * src/SDCCcse.c: fixed bug #514308
9026 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9029 Fixed BUG #519583. If a conditional block ended in a return/break
9030 statement inside a loop, it was not being considered part of the loop.
9032 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9034 2002-02-10 Karl Bongers <karl AT turbobit.com>
9037 Fixed up SDCDB debugger somewhat. Updated debugger/README
9038 with lots of comments and notes.
9040 * device/examples/test2.c:
9041 Fix bug, "red" variable not being initialized(compiler complained).
9043 * device/examples/Makefile, examples/test3.c:

9045 for use as a multiple module SDCDB test case.
9047 * sim/ucsim/cmd.src/cmdset.cc:
9048 Took out debug printfs in ucsim "next" command.
9051 Karl and Johan start ucsim XA support. Most dissassembly working,
9052 about 75% emulation done(plenty of work remaining).
9054 * sim/ucsim/z80.src:
9055 Add Z80 support to ucsim, add test-ucz80 regression test,
9056 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

9092 set preprocessor defines (depending on options)
9094 * src/SDCCicode.c, src/SDCCicode.h:
9095 changes made to handle multiple sends & receives
9098 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
