1473 * src/SDCCglobal.h (struct options),
1475 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1476 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1477 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1478 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1479 always available in leading double underscore form. The C99 support is

1560 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1562 * device/lib/printf_large.c: removed inline assembly for portability and
1563 readability. Use printf_fast if speed or size are more important.
1564 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1565 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1567 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1569 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1570 prevent compiler warning
1572 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1574 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1575 moved to level 0 and declared as static. Also they are explicit
1576 placed in access bank. This was necessery because some times they
1577 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1578 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1579 optimizations. Currently only compare to unsigned char is implemented,
1580 * src/pic16/gen.c: added fReturnIdx array,
1581 * (struct resolvedIfx) is moved to gen.h and made public,
1582 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1583 * (aopForSym): added an optimization to directly store in stack of
1584 the operand of a SEND iCode,
1585 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1586 but as registers instead (AOP_REG) using the fReturnIdx array,
1587 * (pic16_freeAsmop): remove the freed register from the
1588 _G.sregsAlloc field,
1589 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1590 a compare of 'WREG',
1591 * (pic16_popGetTempRegCond): changed function prototype, now
1592 function takes also a bitVector argument v which holds the current
1593 set of registers that are allocated for stack access by aopForSym,
1594 registers allocated in aopForSym for accessing stack symbols are not
1595 any more part of the functions usedRegs field,
1596 * (genCall): some times aopOp is called for a stack variable to be
1597 send, aopForSym might perform the push, if this is true make sure
1598 that genCall doesn't push the variable twice by testing _G.resDirect,
1599 * (genFunction): changed testing for unspecified interrupt number
1600 from 256 to INTNO_UNSPEC,
1601 * modified selection scheme of frame pointer generation. Previously
1602 if function did use local registers a frame pointer was generated,
1603 now a frame pointer is generated only if function has arguments
1604 (that need PLUSW2 register access), or has stack arguments, or the
1605 compiler is not instructed to omit the frame pointer,
1606 * (genEndFunction): before restoring local registers that were saved
1607 in the function preamble, also restore the registers that *might*
1608 have been allocated for stack access,
1609 * (genRet): removed some old comments,
1610 * (genCmp, the active (RN's) version): added a call to the
1611 pic16_genCmp_special function to perform the compare with a more
1612 robust and optimized way,
1613 * (genInline): a feature has been added in inline code generation,
1614 which allows a wildcard variable substitution when writing inline
1615 assembly. Code is incomplete and experimental therefore undocumented,
1616 * (genCast): changed order of aopOp for result and right to allow
1617 aopForSym to directly load the result if possible,
1618 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1619 perform an optimized compare on some selected special occasions,
1620 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1621 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1622 generate an IVT any more,
1623 * src/pic16/main.c (pic16_optionsTable): added command line option
1625 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1626 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1628 * src/pic16/NOTES: Raphael Neider added in list of active developers
1629 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1630 jumptable_end to prevent bug #,
1631 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1632 inCond and outCond fields,
1633 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1634 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1635 turn off register spilling,
1636 * (packRegsForOneUse): synced with other ports' versions although it
1637 is not used currently,
1638 * (pic16_packRegisters): added an optimization while reading
1639 structure bitfields, some registers may be saved (malloc code is
1640 decreased by 80 bytes)
1642 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1644 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1645 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1646 this can be optimized more?
1648 2005-03-10 Raphael Neider <rneider AT web.de>
1650 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1651 genNearPointerGet): (hopefully) fixed access to bitfields via
1652 pointers (p->bitN = x; and x = p->bitN; failed)

1697 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1698 to keep the correct label reference count when adding/removing references
1699 to labels. A peephole file using this is appended to patch #1144962.

2286 Adding support for replacing ljmps with sjmps in jumptables
2287 generated for switch statements. For now you need to set the
2288 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2289 Now 4 algorithms for mcs51 jumptable generation are used:
2290 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2291 addresses loaded pc-relative for up to 112 cases and stack-pushing
2292 target addresses loaded with offset from dptr for up to 256 cases.

2322 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2324 * added libc directory. The current version of LibC contains string
2325 functions, ctype functions and macros and some functions of the
2326 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2327 be extensively tested in the future. Standard disclaimer here.
2328 Library is not automatically build yet. But one can build it by
2329 invoking 'make' inside the libc directory.

2340 * (pic16_storeForReturn): optimized return of 0,
2341 * (genCmp): experimental code for new genCmp which uses PIC18's
2342 special compare&skip instructions. Initial tests fail some times
2343 with variables grater than 1 byte in size, so new code is disabled,
2344 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2346 * (genCast): began a fix to optimize the casting of a bit to another
2347 bit, now assigning a bitfield to another bitfield will fail, sorry,

2361 registers when it shouldn't,
2362 * src/pic16/ralloc.c (allocReg): add preliminary support for
2363 supporting a limited set of temporary registers,
2365 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2367 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

2371 (genFunction): optimize RECEIVE iCodes in reentrant functions
2373 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5253 2004-01-27 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5255 * ChangeLog: changed "@" to " AT " in hopes of reducing spam and
5256 virus/worm forged address usage.
5258 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
5260 Fixed promotion, it should be done on AST level:
5261 * src/SDCCast.c (addCast): added promotion to int

5276 * support/regression/generate-cases.py (main): Changed from inline
5279 * doc/Makefile (install): Changed to depth first to get rid of
5280 missing directory install warning.
5282 * as/Makefile (install-doc): Made work on Mac.
5284 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
5286 * src/SDCCast.c: added an additional type flow in decorateType() of
5287 opposite direction, see feature request #860006; it's enabled at runtime
5288 by setting the environment variable SDCC_NEWTYPEFLOW
5289 * src/SDCCast.h: changed prototype of decorateType()
5290 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
5291 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
5292 'char' to 'int' can be omitted, if both operands are 'unsigned char';
5293 see feature request #877103
5294 * src/SDCCval.c: updated call of decorateType()
5295 (valBitwise): fixed bug #882876
5296 (valMinus): added promotion
5297 (valLogicAndOr): result is unsigned
5298 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
5299 * src/SDCCsymt.c (computeType),
5300 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'

5322 * src/pic/ralloc.h: applied patch from Slade Rich;
5323 added support for multiple code pages and multiple RAM banks on the
5324 PIC 14 port. The ASM files now no longer simply assume all the
5325 code / RAM are in the same page / bank. This means the linker can
5326 safely allocate code/RAM of separate ASM files to different pages/banks.
5327 * doc/sdccman.lyx: added Slade's tips
5328 * src/mcs51/peeph.def: fixed bug #880768

5370 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5372 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5373 loaded with the linker search paths (-L arguments) and the libraries
5374 to be linked with the current source (-l arguments). Changes
5375 currently will affect only the pic16 port.
5376 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5377 include path the port specific paths and port specific libraries,
5378 * gplink command now contains the $3 argument,
5379 * src/pic16/device.h,
5380 * src/pic16/device.c,: structure PIC_device is made public and
5381 renamed to PIC16_device, the same for variable Pics which is renamed

5396 Documenting changes from previous commits.
5397 * configure.in (version 1.56),
5398 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5399 when generating output files to configure the pic16 library,
5400 but now I've commented it out, since gputils aren't installed in the
5401 SF compile farm, so library won't compile
5403 * device/lib/Makefile.in (version 1.56): initially I've added in
5404 target 'all' the prerequestive 'model-pic16' so it compiled the
5405 pic16 library, but now I've commented it out for the same reasons
5407 * added targets 'model-pic16' and 'objects-pic16' to compile the
5409 * added target 'port-specific-objects-pic16' to handle the
5410 generated libraries and copy them into the build/ directory
5411 * added target 'clean-intermediate-pic16' to clean intermediate
5412 files into pic16 directory
5413 * in target 'installdirs' added line to create directory pic16 in
5414 the installation path
5416 * device/include/Makefile.in (version 1.11): in target 'install'
5417 added lines to copy all header files to installation path,
5418 * in target 'installdirs' added line create directory for pic16
5419 headers in the installation path

5434 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5435 option so that it actually works. Made it specific to the z80, since
5436 the gbz80 doesn't have these kinds of I/O ports.
5438 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5440 * device/include/z180.h,

5462 Mainly changes to support compilation of the device libraries
5463 * src/pic16/device.c: stack is allocated via symbol and not
5464 via literal number. The symbol is placed in the corresponding
5465 position of the data ram
5466 * (pic16_dump_section): relocatable and absolute uninitialized
5467 data are now emitted in sorted order to reduce section naming,
5468 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5469 weren't marked as being in the access bank,
5471 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5473 Added portion of GNU PIC Library under the directory
5474 device/include/pic16 and device/lib/pic16. These files
5475 contain the declarations of SFRs for the PIC18Fxx2 devices.
5476 The directory is initialized via configure from toplevel.

5506 all over. Telling LaTeX to be less strict with word spacing
5507 to better keep the right margin. Changed some notes about
5508 maintainance of the ports in section 3.2.1 - is it OK like this?
5510 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5550 * src/pic16/peeph.def: all peepholes with movff are commented out,
5551 because there is a problem in the pcode peep optimizer,
5552 * src/pic16/ralloc.c: the register allocator can now reuse local

5691 Bug reported from Jesus Calvino-Fraga
5693 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5695 * sdcc.spec: updated

5704 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5706 PIC16 port related changes:
5707 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5708 added variable stackPos,
5710 * gen.c: genCall, assignResultValue: added support for
5711 pushing/retrieving function parameters to/from stack,
5712 genFunction,genEndFunction: setup stack frame for the
5714 genAddrOf: will be changed according to bug 863624
5716 * added files genutils.c and genutils.h which contain gen*
5717 debugged and optimised functions extracted from gen.c
5719 * glue.c: added variable 'externs' which holds extern symbols,
5720 pic16emitRegularMap: is modified to properly handle relocatable
5721 symbols under the new scheme,
5722 pic16createInterruptVect: is modified
5723 pic16printPublics: is modified to emit 'global' assembler directives,
5724 added pic16_printExterns to print extern symbols,
5725 pic16glue: initializes stack/frame pointer in the beginning of
5726 the assembly output. Temporary hack, will be corrected later,
5727 because gplink yet does not support stack and SDCC does not
5728 yet support a type of crt0.o object to create the final binary.
5730 * Removed many lines that contain 8051 legacy code.
5731 * The code is finally placed under a 'code' directive.
5732 * Added port specific options.
5734 * _process_pragma: simplified since now we do not need *special*
5735 include file to define SFR registers. But a separate header
5736 will be needed. This will be developed later.
5737 * _pic16_parseOptions: added, parses port specific options:
5738 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5739 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5740 --preplace-udata-with=
5742 * _pic16_setDefaultOptions: modified to initialize section names,
5743 but hack is temporarly out of order since it needs improvement.
5744 * _pic16_genAssemblerPreamble: configuration words are emitted by
5745 their address instead of their name. This part is incomplete and
5746 supports only the 18Fxx2 devices. Other devices will emit an error
5747 during assembly since they do not contain the same set of config
5749 * _pic16_genIVT: is modified,
5751 * pcode.c: added definitions for some hardware registers that are needed
5753 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5754 All PCI entries are updated. Now LFSR is supported.
5755 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5756 * added pic16_newpCodeOpLit2 to support instructions with
5757 two literal arguments
5758 * pic16_pCode2str: corrected code that emits assembler instructions
5759 with two literal operands and those that have an access bit modifier
5760 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5761 this fixes a bug which caused some labels to be lost, when an
5762 assembler directive was added, i.e. banksel,
5763 * pic16_FixRegisterBanking: improved logic that causes the insertion
5765 * InlineFunction: functions that are called once, are not any more
5766 inlined. This can be a port option in the future,
5768 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5770 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5771 hold the corresponding uninitialized symbols,
5772 * pic16_allocProcessorRegister: registers have explicit marked the
5774 * pic16_allocInternalRegister: registers are explicit marked as
5776 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5777 processing list, so bit registers were lost,
5780 * ralloc.h: added field 'accessBank' and original symbol operand
5781 in register definition,
5782 * removed the field isMapped from register definition,
5784 ** Several functions have been removed from various sources:
5785 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5786 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5787 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5788 pic16_assignRelocatableRegisters
5790 ** others have been introduced:
5791 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5792 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5794 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5796 * support/scripts/inc2h.pl: changed definition of BIT_AT
5797 to emit 'sbit at' instead of 'bit at'. This was a request.
5799 PIC16 port related preliminary changes:
5800 * gen.c: prefixed function popRegFromString with
5801 pic16_ and all references to it corrected
5802 * pcode.c: all pic16_pc_* hardware registers prefixed
5803 with underscore (_),
5804 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5805 * ralloc.c: newReg(): when register is REG_SFR then
5806 set address to rIdx,
5807 pic16_allocProcessorRegister(): marks register wasUsed=0
5808 pic16_writeUsedRegs(): added a call to assign processor
5809 registers via pic16_assignFixedRegisters
5811 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5813 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5814 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5815 variables in unused register banks. Also the SSEG is placed
5816 wherever there is enough space for it, and IDATA can be anywhere
5817 in internal RAM. For now compile using -Wl-Y[stack_size].
5818 The mem file is different for this option as well, since it
5819 makes no sense of talking about DSEG lenght.
5821 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5823 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5824 in certain cases, e.g. when ROM assignment, patch provided
5825 from Albert den Haan.

6068 * src/SDCCast.c (decorateType): disabled a transformation I added in
6069 revision 1.188 (access to fields of a structure at an absolute address);
6070 it breaks with bitfields, extern declarations, and gcse analysis.
6071 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6072 could be assigned through a pointer, so don't complain.

6180 xdata initialization slightly shorter
6182 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6829 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6830 fetching of the pointer
6831 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6832 copied from genNearPointerSet()
6833 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6834 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6850 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6851 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6852 type for bits was changed. It resulted in bit variables becoming
6853 global, which is not permitted in PIC 14 assembly output.
6855 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6857 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6870 A few small changes that speed up the peephole optimizer.
6874 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6876 Try to make the peephole optimizer smarter by maintaining
6877 an association between the assembly source code and the
6878 iCodes that originated them. Put this information to use
6879 with a new peephole rule condition "notVolatile" so that
6880 the rules can be aggressive yet still safe.
6885 * src/mcs51/peeph.def
6887 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6891 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6892 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6893 if the left or right operand symbols have the accuse flag set.
6895 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6897 Changed the type of the result of the ! (NOT) operator to char;
6898 previously it returned the same type as the source. This allows
6899 us to eliminate all the genFloatNot functions (all of its target
6900 implementations were very buggy) since !float can use the same
6903 * src/SDCCicode.c (ast2iCode): ! returns char

6912 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6913 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6914 during interrupts. Ensure WSAVE is located at a shared bank address.
6915 2. Fixed page selection in some places
6916 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6917 the registers name strings.
6918 4. Fixed "signed / unsigned compare" compiler warnings.
6919 5. The PIC port manages its own allocation of the general purpose
6920 registers, but makes no attempt to reuse them. As a result when
6921 compiling it soon runs out of general purpose registers. Some
6922 additional code was added to the files pcode.c and device.c to walk
6923 through the function call tree and rename the registers so that they
6933 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6934 genPlus() & genMinus() when the result is the same as left or right

6940 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6942 Made bitfield a distinct type from bit so that bitfields
6943 convert as per ANSI C and bits retain their traditional
6944 boolean style behaviour. Implemented bitfield support in
6952 * src/ds390/gen.c: bit v bitfield split
6953 * src/z80/gen.c: New support for bitfields
6954 * support/regression/tests/bitfields.c: reenabled z80,
6957 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6959 Rules 246.x, 247.x relate to bitfields, the others speed up
6960 access to xdata mapped I/O devices.
6962 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6964 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6966 Cleaned up genPackBits and genUnpackBits and added two helper
6967 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6968 for literal assignments in genPackBits (thanks to Frieder for
6974 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6976 Fixed bug #748310 (pointer to function type mishandled when the
6977 function name is omitted). Also fixed a SIGSEGV when a function
6978 attribute (reentrant, etc) is used on a non-function or on a
6979 function but misplaced before the parameter list.
6981 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6983 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6984 * support/Util/SDCCerr.h,

7006 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7008 Made the constant following the "interrupt" keyword optional. If
7009 omitted, the function will not automatically be given an entry
7010 in the interrupt vector table (similar to #pragma NOIV, but
7011 less syntacticly kludgy). The interrupt number is also now
7012 range checked. Also fixed a bug in the high order bit example
7019 * support/Util/SDCCerr.c
7020 * support/Util/SDCCerr.h
7023 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7026 * src/SDCCicode.c (operandOperation): rewritten some ops
7027 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7028 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7030 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7031 be re-activated by defining REDUCE_LITERALS)
7032 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7033 unsigned, but are signed by default
7034 * src/SDCCval.c (constVal): rearranged
7035 * src/SDCCval.c (valMod): preliminary fix
7036 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7078 constants are unsigned; added recognition of "u" flag for unsigned
7079 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7080 * src/SDCCval.c (valDiv, valMod): fixed signdness
7081 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7082 signedness of modulo, left and right shift

7539 added --disable-pic16-port
7540 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7541 * src/SDCCmain.c: linkOptions is changed to set *,
7542 added if/endif conditional macros to remove options help
7543 messages from optionsTable when a port is not configured, added
7544 support for the PIc16 port in the ports table, when executing
7545 the compiler with no port specified on command line, a default
7546 port is selected with the new macro DEFAULT_PORT which is
7547 defined in port.h, in setDefaultOptions() linkOptions is removed
7548 from initialization assignment, since now it is a set,
7549 parseCmdLine uses setParseWithComma for linkOptions, in
7550 linkEdit() linkOptions are accessed with new function indexSet()
7551 which returns the i'th item of a set variable. See SDCCset.c, in
7552 linkEdit() when calling buildCmdLine(), added linkOptions as
7553 last argument. Now users can pass arguments to gplink via the
7554 -Wl option, main() uses pic16glue() to glue up pic16 programs

7566 * src/pic16/glue.c: commented out some error producing lines
7567 * src/pic16/main.c: __config directives are commented out to stop
7568 gpasm complaining and test the linkage with gplink, _linkCmd and
7569 _asmCmd changed to be more gplink and gpasm friendly
7570 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7571 produced an error when parsed, peep rule 12 is added to utilize
7572 movff, but it is commented out since the pCode does not support
7573 yet a command with 2 address arguments
7575 2003-05-18 <johan AT balder>
7577 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7578 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7604 2003-05-11 Borut Razem <borut.razem AT siol.net>
7606 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7607 the path of bin directory, so that PATH is the only env. variable, which has to be set
7608 in case of standard installation.
7609 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

8666 added aopGetUsesAcc() function to allow binary operators to
8667 fetch their operands in the correct order; made genMinus() emit
8668 compact code for X = LITERAL - Y
8670 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8671 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8672 sprintf() in line 1267.
8674 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8675 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8678 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8679 Changes to aslink (All the changes are marked with 'JCF'):
8681 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8684 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8685 area BSEG. Also moves, if possible, the DATA area down into the internal
8686 ram so more space is available.
8688 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8691 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8692 not bytes. Function summary() which creates a memory usage summary
8693 file with extension .mem. Reports of overlaping stack and small stack
8694 size. If the space for the stack is less than 16 bytes aslink trows a
8697 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8698 the 8051. Option 'y' for memory summary output file.
8700 Changes to sdcc (All the changes are marked with 'JCF'):
8702 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8704 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8705 overlaying area for it (uses RegBankUsed[4]).
8707 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8708 bank zero as used by default. By default aslink locates the stack
8709 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8710 the creation of the .mem file. Delegates the allocation of data area
8711 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8712 the begining of the stack area to aslink.
8714 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8715 glue() in SDCCglue.c creates an area for it.
8717 2002-09-03 Borut Razem <borut.razem AT siol.net>
8718 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8719 sdcc/src/pic/glue.c:
8720 introduced atexit() handler for teporay files removal in case of
8721 errors, assertions, ...
8723 2002-08-29 Borut Razem <borut.razem AT siol.net>
8724 * sdcc/support/cpp2/auto-host_vc_in.h:
8725 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8726 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8727 Maybe there is a similar problem with BORLANDC? It should be checked!
8729 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8730 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8731 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8732 was not executed, and the compiler (cl) launched a warning:
8733 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8735 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8736 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8738 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8739 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8741 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8742 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8743 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8744 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8745 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8746 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8747 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8748 - added Release configuration in VS projects
8749 - review of compiler an linker options
8750 - VC .exe files are generated in bin_vc directory, not to interfere
8751 with binaries generated from other projects (cygwin, mingw, bcc ...)
8753 * sdcc/src/yacc.dsp: added
8755 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8756 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8757 and insert the version number definitions from .version
8759 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8761 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8762 added - genarate auto-host.h using auto-host_vc_in.h as template
8765 removed from CVS, generated automatically
8767 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8768 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8770 2002-08-11 Borut Razem <borut.razem AT siol.net>
8771 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8773 2002-08-10 Borut Razem <borut.razem AT siol.net>
8774 * src/SDCCmain.c (main):
8775 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8776 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8777 The consequence was that some temporary files were not removed.
8780 unification of code in functions tempfilename() and tempfile():
8781 function tempnam() is defined in Visual Studio 6.0 and .NET
8783 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8785 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8786 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8787 - removed compiler command line option /WX: Treats all warnings as errors
8788 - update a list of source files, included into the project
8790 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8791 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8792 changed project type to Generic Project so that can be correcly converted to VS.NET project
8794 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8796 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8798 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8800 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8801 added return 0 statements after assert() to make compiler happy
8803 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8804 added newline in the def file to keep MSC compiler satisfied
8806 * sdcc/src/z80/gen.c:
8807 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8808 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8809 - solved MSC error in function aopDump()
8811 * sdcc_vc.h: define PREFIX as "\\sdcc"
8813 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8814 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8857 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8859 Added "char *Processor" field to the port structure.
8862 Added -p option. Allows port dependent processor to be specified.
8865 Initialized the new field char *Processor field to NULL in all ports
8868 Compiler generated registers for interrupt context saving
8869 were not getting allocated.
8871 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8874 Fixed left shift. Will promote the left side of a left shift
8875 if a) left shifting more than size of operand or b) when assigned
8876 to something size > size of left side
8878 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8880 tons of changes. Register allocation has been
8881 rewritten. Added customization for the various PICs. Flow

8986 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
8988 * sdcc/src/SDCCloop.c:
8989 Previous fix was not good. basic blocks that have "break" or "return" are
8990 not really partof a loop , but live ranges used in these blocks should
8991 be live thru the entire loop, so set partOfLoop but don't add them to
8994 2002-02-21 <johan AT FRIJA>
8996 * src/SDCCcse.c: fixed bug #514308
8998 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9001 Fixed BUG #519583. If a conditional block ended in a return/break
9002 statement inside a loop, it was not being considered part of the loop.
9004 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9006 2002-02-10 Karl Bongers <karl AT turbobit.com>
9009 Fixed up SDCDB debugger somewhat. Updated debugger/README
9010 with lots of comments and notes.
9012 * device/examples/test2.c:
9013 Fix bug, "red" variable not being initialized(compiler complained).
