1481 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1482 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1483 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1484 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1485 always available in leading double underscore form. The C99 support is
1486 mostly missing, but it's a start.
1487 * support/regression/tests/bug-227710.c: fixed nonconforming use of

1566 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1568 * device/lib/printf_large.c: removed inline assembly for portability and
1569 readability. Use printf_fast if speed or size are more important.
1570 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1571 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1573 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1575 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1576 prevent compiler warning
1578 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1580 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1581 moved to level 0 and declared as static. Also they are explicit
1582 placed in access bank. This was necessery because some times they
1583 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1584 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1585 optimizations. Currently only compare to unsigned char is implemented,
1586 * src/pic16/gen.c: added fReturnIdx array,
1587 * (struct resolvedIfx) is moved to gen.h and made public,
1588 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1589 * (aopForSym): added an optimization to directly store in stack of
1590 the operand of a SEND iCode,
1591 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1592 but as registers instead (AOP_REG) using the fReturnIdx array,
1593 * (pic16_freeAsmop): remove the freed register from the
1594 _G.sregsAlloc field,
1595 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1596 a compare of 'WREG',
1597 * (pic16_popGetTempRegCond): changed function prototype, now
1598 function takes also a bitVector argument v which holds the current
1599 set of registers that are allocated for stack access by aopForSym,
1600 registers allocated in aopForSym for accessing stack symbols are not
1601 any more part of the functions usedRegs field,
1602 * (genCall): some times aopOp is called for a stack variable to be
1603 send, aopForSym might perform the push, if this is true make sure
1604 that genCall doesn't push the variable twice by testing _G.resDirect,
1605 * (genFunction): changed testing for unspecified interrupt number
1606 from 256 to INTNO_UNSPEC,
1607 * modified selection scheme of frame pointer generation. Previously
1608 if function did use local registers a frame pointer was generated,
1609 now a frame pointer is generated only if function has arguments
1610 (that need PLUSW2 register access), or has stack arguments, or the
1611 compiler is not instructed to omit the frame pointer,
1612 * (genEndFunction): before restoring local registers that were saved
1613 in the function preamble, also restore the registers that *might*
1614 have been allocated for stack access,
1615 * (genRet): removed some old comments,
1616 * (genCmp, the active (RN's) version): added a call to the
1617 pic16_genCmp_special function to perform the compare with a more
1618 robust and optimized way,
1619 * (genInline): a feature has been added in inline code generation,
1620 which allows a wildcard variable substitution when writing inline
1621 assembly. Code is incomplete and experimental therefore undocumented,
1622 * (genCast): changed order of aopOp for result and right to allow
1623 aopForSym to directly load the result if possible,
1624 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1625 perform an optimized compare on some selected special occasions,
1626 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1627 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1628 generate an IVT any more,
1629 * src/pic16/main.c (pic16_optionsTable): added command line option
1631 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1632 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1634 * src/pic16/NOTES: Raphael Neider added in list of active developers
1635 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1636 jumptable_end to prevent bug #,
1637 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1638 inCond and outCond fields,
1639 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1640 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1641 turn off register spilling,
1642 * (packRegsForOneUse): synced with other ports' versions although it
1643 is not used currently,
1644 * (pic16_packRegisters): added an optimization while reading
1645 structure bitfields, some registers may be saved (malloc code is
1646 decreased by 80 bytes)
1648 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1650 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1651 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1652 this can be optimized more?
1654 2005-03-10 Raphael Neider <rneider AT web.de>
1656 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1657 genNearPointerGet): (hopefully) fixed access to bitfields via
1658 pointers (p->bitN = x; and x = p->bitN; failed)

1703 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1704 to keep the correct label reference count when adding/removing references
1705 to labels. A peephole file using this is appended to patch #1144962.
1707 2005-02-14 Raphael Neider <rneider AT web.de>

2292 Adding support for replacing ljmps with sjmps in jumptables
2293 generated for switch statements. For now you need to set the
2294 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2295 Now 4 algorithms for mcs51 jumptable generation are used:
2296 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2297 addresses loaded pc-relative for up to 112 cases and stack-pushing
2298 target addresses loaded with offset from dptr for up to 256 cases.

2328 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2330 * added libc directory. The current version of LibC contains string
2331 functions, ctype functions and macros and some functions of the
2332 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2333 be extensively tested in the future. Standard disclaimer here.
2334 Library is not automatically build yet. But one can build it by
2335 invoking 'make' inside the libc directory.

2346 * (pic16_storeForReturn): optimized return of 0,
2347 * (genCmp): experimental code for new genCmp which uses PIC18's
2348 special compare&skip instructions. Initial tests fail some times
2349 with variables grater than 1 byte in size, so new code is disabled,
2350 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2352 * (genCast): began a fix to optimize the casting of a bit to another
2353 bit, now assigning a bitfield to another bitfield will fail, sorry,

2362 and 1 for banking instruction,
2363 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2364 caused stop processing pCodes after a inline assembly block,
2365 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2367 registers when it shouldn't,
2368 * src/pic16/ralloc.c (allocReg): add preliminary support for
2369 supporting a limited set of temporary registers,
2371 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2373 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

2377 (genFunction): optimize RECEIVE iCodes in reentrant functions
2379 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2381 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5259 2004-01-27 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5261 * ChangeLog: changed "@" to " AT " in hopes of reducing spam and
5262 virus/worm forged address usage.
5264 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
5266 Fixed promotion, it should be done on AST level:
5267 * src/SDCCast.c (addCast): added promotion to int

5282 * support/regression/generate-cases.py (main): Changed from inline
5285 * doc/Makefile (install): Changed to depth first to get rid of
5286 missing directory install warning.
5288 * as/Makefile (install-doc): Made work on Mac.
5290 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
5292 * src/SDCCast.c: added an additional type flow in decorateType() of
5293 opposite direction, see feature request #860006; it's enabled at runtime
5294 by setting the environment variable SDCC_NEWTYPEFLOW
5295 * src/SDCCast.h: changed prototype of decorateType()
5296 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
5297 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
5298 'char' to 'int' can be omitted, if both operands are 'unsigned char';
5299 see feature request #877103
5300 * src/SDCCval.c: updated call of decorateType()
5301 (valBitwise): fixed bug #882876
5302 (valMinus): added promotion
5303 (valLogicAndOr): result is unsigned
5304 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
5305 * src/SDCCsymt.c (computeType),

5328 * src/pic/ralloc.h: applied patch from Slade Rich;
5329 added support for multiple code pages and multiple RAM banks on the
5330 PIC 14 port. The ASM files now no longer simply assume all the
5331 code / RAM are in the same page / bank. This means the linker can
5332 safely allocate code/RAM of separate ASM files to different pages/banks.
5333 * doc/sdccman.lyx: added Slade's tips
5334 * src/mcs51/peeph.def: fixed bug #880768

5376 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5378 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5379 loaded with the linker search paths (-L arguments) and the libraries
5380 to be linked with the current source (-l arguments). Changes
5381 currently will affect only the pic16 port.
5382 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5383 include path the port specific paths and port specific libraries,
5384 * gplink command now contains the $3 argument,
5385 * src/pic16/device.h,
5386 * src/pic16/device.c,: structure PIC_device is made public and
5387 renamed to PIC16_device, the same for variable Pics which is renamed

5402 Documenting changes from previous commits.
5403 * configure.in (version 1.56),
5404 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5405 when generating output files to configure the pic16 library,
5406 but now I've commented it out, since gputils aren't installed in the
5407 SF compile farm, so library won't compile
5409 * device/lib/Makefile.in (version 1.56): initially I've added in
5410 target 'all' the prerequestive 'model-pic16' so it compiled the
5411 pic16 library, but now I've commented it out for the same reasons
5413 * added targets 'model-pic16' and 'objects-pic16' to compile the
5415 * added target 'port-specific-objects-pic16' to handle the
5416 generated libraries and copy them into the build/ directory
5417 * added target 'clean-intermediate-pic16' to clean intermediate
5418 files into pic16 directory
5419 * in target 'installdirs' added line to create directory pic16 in
5420 the installation path
5422 * device/include/Makefile.in (version 1.11): in target 'install'
5423 added lines to copy all header files to installation path,
5424 * in target 'installdirs' added line create directory for pic16
5425 headers in the installation path

5440 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5441 option so that it actually works. Made it specific to the z80, since
5442 the gbz80 doesn't have these kinds of I/O ports.
5444 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5446 * device/include/z180.h,

5468 Mainly changes to support compilation of the device libraries
5469 * src/pic16/device.c: stack is allocated via symbol and not
5470 via literal number. The symbol is placed in the corresponding
5471 position of the data ram
5472 * (pic16_dump_section): relocatable and absolute uninitialized
5473 data are now emitted in sorted order to reduce section naming,
5474 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5475 weren't marked as being in the access bank,
5477 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5479 Added portion of GNU PIC Library under the directory
5480 device/include/pic16 and device/lib/pic16. These files
5481 contain the declarations of SFRs for the PIC18Fxx2 devices.
5482 The directory is initialized via configure from toplevel.

5512 all over. Telling LaTeX to be less strict with word spacing
5513 to better keep the right margin. Changed some notes about
5514 maintainance of the ports in section 3.2.1 - is it OK like this?
5516 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5556 * src/pic16/peeph.def: all peepholes with movff are commented out,
5557 because there is a problem in the pcode peep optimizer,
5558 * src/pic16/ralloc.c: the register allocator can now reuse local

5697 Bug reported from Jesus Calvino-Fraga
5699 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5701 * sdcc.spec: updated
5702 * device/include/Makefile.in: don't install CVS directories

5710 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5712 PIC16 port related changes:
5713 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5714 added variable stackPos,
5716 * gen.c: genCall, assignResultValue: added support for
5717 pushing/retrieving function parameters to/from stack,
5718 genFunction,genEndFunction: setup stack frame for the
5720 genAddrOf: will be changed according to bug 863624
5722 * added files genutils.c and genutils.h which contain gen*
5723 debugged and optimised functions extracted from gen.c
5725 * glue.c: added variable 'externs' which holds extern symbols,
5726 pic16emitRegularMap: is modified to properly handle relocatable
5727 symbols under the new scheme,
5728 pic16createInterruptVect: is modified
5729 pic16printPublics: is modified to emit 'global' assembler directives,
5730 added pic16_printExterns to print extern symbols,
5731 pic16glue: initializes stack/frame pointer in the beginning of
5732 the assembly output. Temporary hack, will be corrected later,
5733 because gplink yet does not support stack and SDCC does not
5734 yet support a type of crt0.o object to create the final binary.
5736 * Removed many lines that contain 8051 legacy code.
5737 * The code is finally placed under a 'code' directive.
5738 * Added port specific options.
5740 * _process_pragma: simplified since now we do not need *special*
5741 include file to define SFR registers. But a separate header
5742 will be needed. This will be developed later.
5743 * _pic16_parseOptions: added, parses port specific options:
5744 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5745 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5746 --preplace-udata-with=
5748 * _pic16_setDefaultOptions: modified to initialize section names,
5749 but hack is temporarly out of order since it needs improvement.
5750 * _pic16_genAssemblerPreamble: configuration words are emitted by
5751 their address instead of their name. This part is incomplete and
5752 supports only the 18Fxx2 devices. Other devices will emit an error
5753 during assembly since they do not contain the same set of config
5755 * _pic16_genIVT: is modified,
5757 * pcode.c: added definitions for some hardware registers that are needed
5759 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5760 All PCI entries are updated. Now LFSR is supported.
5761 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5762 * added pic16_newpCodeOpLit2 to support instructions with
5763 two literal arguments
5764 * pic16_pCode2str: corrected code that emits assembler instructions
5765 with two literal operands and those that have an access bit modifier
5766 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5767 this fixes a bug which caused some labels to be lost, when an
5768 assembler directive was added, i.e. banksel,
5769 * pic16_FixRegisterBanking: improved logic that causes the insertion
5771 * InlineFunction: functions that are called once, are not any more
5772 inlined. This can be a port option in the future,
5774 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5776 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5777 hold the corresponding uninitialized symbols,
5778 * pic16_allocProcessorRegister: registers have explicit marked the
5780 * pic16_allocInternalRegister: registers are explicit marked as
5782 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5783 processing list, so bit registers were lost,
5786 * ralloc.h: added field 'accessBank' and original symbol operand
5787 in register definition,
5788 * removed the field isMapped from register definition,
5790 ** Several functions have been removed from various sources:
5791 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5792 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5793 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5794 pic16_assignRelocatableRegisters
5796 ** others have been introduced:
5797 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5798 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5800 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5802 * support/scripts/inc2h.pl: changed definition of BIT_AT
5803 to emit 'sbit at' instead of 'bit at'. This was a request.
5805 PIC16 port related preliminary changes:
5806 * gen.c: prefixed function popRegFromString with
5807 pic16_ and all references to it corrected
5808 * pcode.c: all pic16_pc_* hardware registers prefixed
5809 with underscore (_),
5810 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5811 * ralloc.c: newReg(): when register is REG_SFR then
5812 set address to rIdx,
5813 pic16_allocProcessorRegister(): marks register wasUsed=0
5814 pic16_writeUsedRegs(): added a call to assign processor
5815 registers via pic16_assignFixedRegisters
5817 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5819 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5820 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5821 variables in unused register banks. Also the SSEG is placed
5822 wherever there is enough space for it, and IDATA can be anywhere
5823 in internal RAM. For now compile using -Wl-Y[stack_size].
5824 The mem file is different for this option as well, since it
5825 makes no sense of talking about DSEG lenght.
5827 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5829 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5830 in certain cases, e.g. when ROM assignment, patch provided
5831 from Albert den Haan.

6074 * src/SDCCast.c (decorateType): disabled a transformation I added in
6075 revision 1.188 (access to fields of a structure at an absolute address);
6076 it breaks with bitfields, extern declarations, and gcse analysis.
6077 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6078 could be assigned through a pointer, so don't complain.

6186 xdata initialization slightly shorter
6188 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6835 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6836 fetching of the pointer
6837 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6838 copied from genNearPointerSet()
6839 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6840 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6856 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6857 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6858 type for bits was changed. It resulted in bit variables becoming
6859 global, which is not permitted in PIC 14 assembly output.
6861 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6863 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6876 A few small changes that speed up the peephole optimizer.
6880 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6882 Try to make the peephole optimizer smarter by maintaining
6883 an association between the assembly source code and the
6884 iCodes that originated them. Put this information to use
6885 with a new peephole rule condition "notVolatile" so that
6886 the rules can be aggressive yet still safe.
6891 * src/mcs51/peeph.def
6893 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6897 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6898 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6899 if the left or right operand symbols have the accuse flag set.
6901 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6903 Changed the type of the result of the ! (NOT) operator to char;
6904 previously it returned the same type as the source. This allows
6905 us to eliminate all the genFloatNot functions (all of its target
6906 implementations were very buggy) since !float can use the same

6918 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6919 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6920 during interrupts. Ensure WSAVE is located at a shared bank address.
6921 2. Fixed page selection in some places
6922 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6923 the registers name strings.
6924 4. Fixed "signed / unsigned compare" compiler warnings.
6925 5. The PIC port manages its own allocation of the general purpose
6926 registers, but makes no attempt to reuse them. As a result when
6927 compiling it soon runs out of general purpose registers. Some
6928 additional code was added to the files pcode.c and device.c to walk
6929 through the function call tree and rename the registers so that they
6939 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6940 genPlus() & genMinus() when the result is the same as left or right

6946 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6948 Made bitfield a distinct type from bit so that bitfields
6949 convert as per ANSI C and bits retain their traditional
6950 boolean style behaviour. Implemented bitfield support in
6958 * src/ds390/gen.c: bit v bitfield split
6959 * src/z80/gen.c: New support for bitfields
6960 * support/regression/tests/bitfields.c: reenabled z80,
6963 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6965 Rules 246.x, 247.x relate to bitfields, the others speed up
6966 access to xdata mapped I/O devices.
6968 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6970 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6972 Cleaned up genPackBits and genUnpackBits and added two helper
6973 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6974 for literal assignments in genPackBits (thanks to Frieder for
6980 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6982 Fixed bug #748310 (pointer to function type mishandled when the
6983 function name is omitted). Also fixed a SIGSEGV when a function
6984 attribute (reentrant, etc) is used on a non-function or on a
6985 function but misplaced before the parameter list.
6987 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6989 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6990 * support/Util/SDCCerr.h,
6991 * support/Util/SDCCerr.c: Added func attr misuse error msg

7012 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7014 Made the constant following the "interrupt" keyword optional. If
7015 omitted, the function will not automatically be given an entry
7016 in the interrupt vector table (similar to #pragma NOIV, but
7017 less syntacticly kludgy). The interrupt number is also now
7018 range checked. Also fixed a bug in the high order bit example

7032 * src/SDCCicode.c (operandOperation): rewritten some ops
7033 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7034 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7036 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7037 be re-activated by defining REDUCE_LITERALS)
7038 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7039 unsigned, but are signed by default
7040 * src/SDCCval.c (constVal): rearranged
7041 * src/SDCCval.c (valMod): preliminary fix
7042 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7084 constants are unsigned; added recognition of "u" flag for unsigned
7085 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7086 * src/SDCCval.c (valDiv, valMod): fixed signdness
7087 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7088 signedness of modulo, left and right shift

7539 it can be defined with CFLAGS when running configure
7540 * src/SDCCmain.c: fixed compiling + linking with object files
7542 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

7545 added --disable-pic16-port
7546 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7547 * src/SDCCmain.c: linkOptions is changed to set *,
7548 added if/endif conditional macros to remove options help
7549 messages from optionsTable when a port is not configured, added
7550 support for the PIc16 port in the ports table, when executing
7551 the compiler with no port specified on command line, a default
7552 port is selected with the new macro DEFAULT_PORT which is
7553 defined in port.h, in setDefaultOptions() linkOptions is removed
7554 from initialization assignment, since now it is a set,
7555 parseCmdLine uses setParseWithComma for linkOptions, in
7556 linkEdit() linkOptions are accessed with new function indexSet()
7557 which returns the i'th item of a set variable. See SDCCset.c, in
7558 linkEdit() when calling buildCmdLine(), added linkOptions as
7559 last argument. Now users can pass arguments to gplink via the
7560 -Wl option, main() uses pic16glue() to glue up pic16 programs

7572 * src/pic16/glue.c: commented out some error producing lines
7573 * src/pic16/main.c: __config directives are commented out to stop
7574 gpasm complaining and test the linkage with gplink, _linkCmd and
7575 _asmCmd changed to be more gplink and gpasm friendly
7576 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7577 produced an error when parsed, peep rule 12 is added to utilize
7578 movff, but it is commented out since the pCode does not support
7579 yet a command with 2 address arguments
7581 2003-05-18 <johan AT balder>
7583 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7584 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7610 2003-05-11 Borut Razem <borut.razem AT siol.net>
7612 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7613 the path of bin directory, so that PATH is the only env. variable, which has to be set
7614 in case of standard installation.
7615 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8672 added aopGetUsesAcc() function to allow binary operators to
8673 fetch their operands in the correct order; made genMinus() emit
8674 compact code for X = LITERAL - Y
8676 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8677 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8678 sprintf() in line 1267.
8680 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8681 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8684 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8685 Changes to aslink (All the changes are marked with 'JCF'):
8687 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8690 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8691 area BSEG. Also moves, if possible, the DATA area down into the internal
8692 ram so more space is available.
8694 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8697 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8698 not bytes. Function summary() which creates a memory usage summary
8699 file with extension .mem. Reports of overlaping stack and small stack
8700 size. If the space for the stack is less than 16 bytes aslink trows a
8703 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8704 the 8051. Option 'y' for memory summary output file.
8706 Changes to sdcc (All the changes are marked with 'JCF'):
8708 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8710 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8711 overlaying area for it (uses RegBankUsed[4]).
8713 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8714 bank zero as used by default. By default aslink locates the stack
8715 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8716 the creation of the .mem file. Delegates the allocation of data area
8717 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8718 the begining of the stack area to aslink.
8720 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8721 glue() in SDCCglue.c creates an area for it.
8723 2002-09-03 Borut Razem <borut.razem AT siol.net>
8724 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8725 sdcc/src/pic/glue.c:
8726 introduced atexit() handler for teporay files removal in case of
8727 errors, assertions, ...
8729 2002-08-29 Borut Razem <borut.razem AT siol.net>
8730 * sdcc/support/cpp2/auto-host_vc_in.h:
8731 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8732 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8733 Maybe there is a similar problem with BORLANDC? It should be checked!
8735 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8736 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8737 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8738 was not executed, and the compiler (cl) launched a warning:
8739 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8741 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8742 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8744 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8745 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8747 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8748 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8749 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8750 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8751 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8752 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8753 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8754 - added Release configuration in VS projects
8755 - review of compiler an linker options
8756 - VC .exe files are generated in bin_vc directory, not to interfere
8757 with binaries generated from other projects (cygwin, mingw, bcc ...)
8759 * sdcc/src/yacc.dsp: added
8761 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8762 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8763 and insert the version number definitions from .version
8765 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8767 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8768 added - genarate auto-host.h using auto-host_vc_in.h as template
8771 removed from CVS, generated automatically
8773 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8774 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8776 2002-08-11 Borut Razem <borut.razem AT siol.net>
8777 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8779 2002-08-10 Borut Razem <borut.razem AT siol.net>
8780 * src/SDCCmain.c (main):
8781 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8782 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8783 The consequence was that some temporary files were not removed.
8786 unification of code in functions tempfilename() and tempfile():
8787 function tempnam() is defined in Visual Studio 6.0 and .NET
8789 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8791 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8792 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8793 - removed compiler command line option /WX: Treats all warnings as errors
8794 - update a list of source files, included into the project
8796 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8797 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8798 changed project type to Generic Project so that can be correcly converted to VS.NET project
8800 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8802 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8804 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8806 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8807 added return 0 statements after assert() to make compiler happy
8809 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8810 added newline in the def file to keep MSC compiler satisfied
8812 * sdcc/src/z80/gen.c:
8813 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8814 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8815 - solved MSC error in function aopDump()
8817 * sdcc_vc.h: define PREFIX as "\\sdcc"
8819 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8820 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8823 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8824 - Rewrote the register banking algorithm.
8825 - Added pCode live-range analysis to registers (for now, only non-used and
8826 singly-used registers optimized away)
8828 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8830 * 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.

8859 2002-03-28 Johan Knol <johan AT balder>
8861 * src/SDCCval.c: fixed bug #532436
8863 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8865 Added "char *Processor" field to the port structure.
8868 Added -p option. Allows port dependent processor to be specified.
8871 Initialized the new field char *Processor field to NULL in all ports
8874 Compiler generated registers for interrupt context saving
8875 were not getting allocated.
8877 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8880 Fixed left shift. Will promote the left side of a left shift
8881 if a) left shifting more than size of operand or b) when assigned
8882 to something size > size of left side
8884 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8886 tons of changes. Register allocation has been
8887 rewritten. Added customization for the various PICs. Flow
8888 analysis is restructured. ...
8894 Added. device.c is a PIC port hack to accomodate variations
8897 2002-03-13 Michael Hope <michaelh AT vroom>
8899 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
8901 2002-03-04 johanknol <johanknol AT manik>

8992 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8994 * sdcc/src/SDCCloop.c:
8995 Previous fix was not good. basic blocks that have "break" or "return" are
8996 not really partof a loop , but live ranges used in these blocks should
8997 be live thru the entire loop, so set partOfLoop but don't add them to
9000 2002-02-21 <johan AT FRIJA>
9002 * src/SDCCcse.c: fixed bug #514308
9004 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9007 Fixed BUG #519583. If a conditional block ended in a return/break
9008 statement inside a loop, it was not being considered part of the loop.
9010 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9012 2002-02-10 Karl Bongers <karl AT turbobit.com>
9015 Fixed up SDCDB debugger somewhat. Updated debugger/README
9016 with lots of comments and notes.
9018 * device/examples/test2.c:
9019 Fix bug, "red" variable not being initialized(compiler complained).
9021 * device/examples/Makefile, examples/test3.c:
9022 Add Makefile in device/examples folder, compiles test3.c
9023 for use as a multiple module SDCDB test case.
9025 * sim/ucsim/cmd.src/cmdset.cc:
9026 Took out debug printfs in ucsim "next" command.
9029 Karl and Johan start ucsim XA support. Most dissassembly working,
9030 about 75% emulation done(plenty of work remaining).
9032 * sim/ucsim/z80.src:
9033 Add Z80 support to ucsim, add test-ucz80 regression test,
9034 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

9070 set preprocessor defines (depending on options)
9072 * src/SDCCicode.c, src/SDCCicode.h:
9073 changes made to handle multiple sends & receives
9076 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
