1720 2005-03-20 Borut Razem <borut.razem AT siol.net>
1722 * support/scripts/inc2h.pl: WIN32 port
1724 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1726 * device/lib/makefile.in: added abs.c and labs.c
1728 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1730 * device/include/stdint.h: added
1731 * device/lib/abs.c: added
1732 * device/lib/labs.c: added
1733 * device/include/stdlib.h: added abs() and labs() prototypes
1734 * device/lib/libsdcc.lib: added abs and labs
1735 * device/include/float.h,
1736 * device/lib/_fsmul.c,
1737 * device/lib/printf_fast.c,
1738 * device/lib/printf_tiny.c: updated comments
1740 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1742 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
1745 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1747 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
1748 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1750 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1752 * device/lib/printf_large.c: removed inline assembly for portability and
1753 readability. Use printf_fast if speed or size are more important.
1754 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1755 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1757 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1759 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1760 prevent compiler warning
1762 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1764 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1765 moved to level 0 and declared as static. Also they are explicit
1766 placed in access bank. This was necessery because some times they
1767 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1768 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1769 optimizations. Currently only compare to unsigned char is implemented,
1770 * src/pic16/gen.c: added fReturnIdx array,
1771 * (struct resolvedIfx) is moved to gen.h and made public,
1772 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1773 * (aopForSym): added an optimization to directly store in stack of
1774 the operand of a SEND iCode,
1775 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1776 but as registers instead (AOP_REG) using the fReturnIdx array,
1777 * (pic16_freeAsmop): remove the freed register from the
1778 _G.sregsAlloc field,
1779 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1780 a compare of 'WREG',
1781 * (pic16_popGetTempRegCond): changed function prototype, now
1782 function takes also a bitVector argument v which holds the current
1783 set of registers that are allocated for stack access by aopForSym,
1784 registers allocated in aopForSym for accessing stack symbols are not
1785 any more part of the functions usedRegs field,
1786 * (genCall): some times aopOp is called for a stack variable to be
1787 send, aopForSym might perform the push, if this is true make sure
1788 that genCall doesn't push the variable twice by testing _G.resDirect,
1789 * (genFunction): changed testing for unspecified interrupt number
1790 from 256 to INTNO_UNSPEC,
1791 * modified selection scheme of frame pointer generation. Previously
1792 if function did use local registers a frame pointer was generated,
1793 now a frame pointer is generated only if function has arguments
1794 (that need PLUSW2 register access), or has stack arguments, or the
1795 compiler is not instructed to omit the frame pointer,
1796 * (genEndFunction): before restoring local registers that were saved
1797 in the function preamble, also restore the registers that *might*
1798 have been allocated for stack access,
1799 * (genRet): removed some old comments,
1800 * (genCmp, the active (RN's) version): added a call to the
1801 pic16_genCmp_special function to perform the compare with a more
1802 robust and optimized way,
1803 * (genInline): a feature has been added in inline code generation,
1804 which allows a wildcard variable substitution when writing inline
1805 assembly. Code is incomplete and experimental therefore undocumented,
1806 * (genCast): changed order of aopOp for result and right to allow
1807 aopForSym to directly load the result if possible,
1808 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1809 perform an optimized compare on some selected special occasions,
1810 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1811 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1812 generate an IVT any more,
1813 * src/pic16/main.c (pic16_optionsTable): added command line option
1815 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1816 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1818 * src/pic16/NOTES: Raphael Neider added in list of active developers
1819 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1820 jumptable_end to prevent bug #,
1821 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1822 inCond and outCond fields,
1823 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1824 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1825 turn off register spilling,
1826 * (packRegsForOneUse): synced with other ports' versions although it
1827 is not used currently,
1828 * (pic16_packRegisters): added an optimization while reading
1829 structure bitfields, some registers may be saved (malloc code is
1830 decreased by 80 bytes)
1832 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1834 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1835 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1836 this can be optimized more?
1838 2005-03-10 Raphael Neider <rneider AT web.de>
1840 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1841 genNearPointerGet): (hopefully) fixed access to bitfields via
1842 pointers (p->bitN = x; and x = p->bitN; failed)
1844 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2477 generated for switch statements. For now you need to set the
2478 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2479 Now 4 algorithms for mcs51 jumptable generation are used:
2480 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

2514 * added libc directory. The current version of LibC contains string
2515 functions, ctype functions and macros and some functions of the
2516 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2517 be extensively tested in the future. Standard disclaimer here.
2518 Library is not automatically build yet. But one can build it by

2530 * (pic16_storeForReturn): optimized return of 0,
2531 * (genCmp): experimental code for new genCmp which uses PIC18's
2532 special compare&skip instructions. Initial tests fail some times
2533 with variables grater than 1 byte in size, so new code is disabled,
2534 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2536 * (genCast): began a fix to optimize the casting of a bit to another
2537 bit, now assigning a bitfield to another bitfield will fail, sorry,

2546 and 1 for banking instruction,
2547 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2548 caused stop processing pCodes after a inline assembly block,
2549 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2551 registers when it shouldn't,
2552 * src/pic16/ralloc.c (allocReg): add preliminary support for
2553 supporting a limited set of temporary registers,
2555 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2561 (genFunction): optimize RECEIVE iCodes in reentrant functions
2563 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2565 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

2579 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
2581 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

5560 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5562 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5563 loaded with the linker search paths (-L arguments) and the libraries
5564 to be linked with the current source (-l arguments). Changes
5565 currently will affect only the pic16 port.
5566 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5567 include path the port specific paths and port specific libraries,
5568 * gplink command now contains the $3 argument,
5569 * src/pic16/device.h,
5570 * src/pic16/device.c,: structure PIC_device is made public and

5586 Documenting changes from previous commits.
5587 * configure.in (version 1.56),
5588 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5589 when generating output files to configure the pic16 library,
5590 but now I've commented it out, since gputils aren't installed in the
5591 SF compile farm, so library won't compile
5593 * device/lib/Makefile.in (version 1.56): initially I've added in
5594 target 'all' the prerequestive 'model-pic16' so it compiled the
5595 pic16 library, but now I've commented it out for the same reasons
5597 * added targets 'model-pic16' and 'objects-pic16' to compile the
5599 * added target 'port-specific-objects-pic16' to handle the
5600 generated libraries and copy them into the build/ directory
5601 * added target 'clean-intermediate-pic16' to clean intermediate
5602 files into pic16 directory
5603 * in target 'installdirs' added line to create directory pic16 in

5607 added lines to copy all header files to installation path,
5608 * in target 'installdirs' added line create directory for pic16
5609 headers in the installation path

5625 option so that it actually works. Made it specific to the z80, since
5626 the gbz80 doesn't have these kinds of I/O ports.
5628 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5630 * device/include/z180.h,

5654 via literal number. The symbol is placed in the corresponding
5655 position of the data ram
5656 * (pic16_dump_section): relocatable and absolute uninitialized
5657 data are now emitted in sorted order to reduce section naming,
5658 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5659 weren't marked as being in the access bank,
5661 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5663 Added portion of GNU PIC Library under the directory
5664 device/include/pic16 and device/lib/pic16. These files
5665 contain the declarations of SFRs for the PIC18Fxx2 devices.
5666 The directory is initialized via configure from toplevel.

5696 all over. Telling LaTeX to be less strict with word spacing
5697 to better keep the right margin. Changed some notes about
5698 maintainance of the ports in section 3.2.1 - is it OK like this?

5709 processor registers declared internally by the port are emitted in
5710 the translation as equates,
5711 * src/pic16/gen.c: inline code is passed unprocessed to the
5713 * (pic16_popGetLit2): fnuction modified to take second operand as

5737 UPPER for immediate operands,
5738 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5740 * src/pic16/peeph.def: all peepholes with movff are commented out,
5741 because there is a problem in the pcode peep optimizer,
5742 * src/pic16/ralloc.c: the register allocator can now reuse local

5852 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5854 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5855 (default behaviour).
5857 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5859 A python script to validate compiler diagnostic messages. It can be
5860 used to verify that sdcc complains about bad c source code and
5861 gives a good location of the error.
5862 * support/valdiag/Makefile,
5863 * support/valdiag/valdiag.py,

5881 Bug reported from Jesus Calvino-Fraga
5883 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5885 * sdcc.spec: updated
5886 * device/include/Makefile.in: don't install CVS directories
5887 * device/lib/Makefile.in: added removal of CVS directories after install
5888 * doc/Makefile: fixed install, added local_icons
5889 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5890 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5891 * src/ds390/gen.c (genRightShift): fixed bug #870788
5892 * src/SDCCast.c (decorateType): fixed bug #870781
5894 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5896 PIC16 port related changes:
5897 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5898 added variable stackPos,
5900 * gen.c: genCall, assignResultValue: added support for
5901 pushing/retrieving function parameters to/from stack,
5902 genFunction,genEndFunction: setup stack frame for the
5904 genAddrOf: will be changed according to bug 863624
5906 * added files genutils.c and genutils.h which contain gen*
5907 debugged and optimised functions extracted from gen.c
5909 * glue.c: added variable 'externs' which holds extern symbols,
5910 pic16emitRegularMap: is modified to properly handle relocatable
5911 symbols under the new scheme,
5912 pic16createInterruptVect: is modified
5913 pic16printPublics: is modified to emit 'global' assembler directives,
5914 added pic16_printExterns to print extern symbols,
5915 pic16glue: initializes stack/frame pointer in the beginning of
5916 the assembly output. Temporary hack, will be corrected later,
5917 because gplink yet does not support stack and SDCC does not
5918 yet support a type of crt0.o object to create the final binary.
5920 * Removed many lines that contain 8051 legacy code.
5921 * The code is finally placed under a 'code' directive.
5922 * Added port specific options.
5924 * _process_pragma: simplified since now we do not need *special*
5925 include file to define SFR registers. But a separate header
5926 will be needed. This will be developed later.
5927 * _pic16_parseOptions: added, parses port specific options:
5928 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5929 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5930 --preplace-udata-with=
5932 * _pic16_setDefaultOptions: modified to initialize section names,
5933 but hack is temporarly out of order since it needs improvement.
5934 * _pic16_genAssemblerPreamble: configuration words are emitted by
5935 their address instead of their name. This part is incomplete and
5936 supports only the 18Fxx2 devices. Other devices will emit an error
5937 during assembly since they do not contain the same set of config
5939 * _pic16_genIVT: is modified,
5941 * pcode.c: added definitions for some hardware registers that are needed
5943 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5944 All PCI entries are updated. Now LFSR is supported.
5945 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5946 * added pic16_newpCodeOpLit2 to support instructions with
5947 two literal arguments
5948 * pic16_pCode2str: corrected code that emits assembler instructions
5949 with two literal operands and those that have an access bit modifier
5950 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5951 this fixes a bug which caused some labels to be lost, when an
5952 assembler directive was added, i.e. banksel,
5953 * pic16_FixRegisterBanking: improved logic that causes the insertion
5955 * InlineFunction: functions that are called once, are not any more
5956 inlined. This can be a port option in the future,
5958 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5960 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5961 hold the corresponding uninitialized symbols,
5962 * pic16_allocProcessorRegister: registers have explicit marked the
5964 * pic16_allocInternalRegister: registers are explicit marked as
5966 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5967 processing list, so bit registers were lost,
5970 * ralloc.h: added field 'accessBank' and original symbol operand
5971 in register definition,
5972 * removed the field isMapped from register definition,
5974 ** Several functions have been removed from various sources:
5975 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5976 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5977 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5978 pic16_assignRelocatableRegisters
5980 ** others have been introduced:
5981 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5982 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5984 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5986 * support/scripts/inc2h.pl: changed definition of BIT_AT
5987 to emit 'sbit at' instead of 'bit at'. This was a request.
5989 PIC16 port related preliminary changes:
5990 * gen.c: prefixed function popRegFromString with
5991 pic16_ and all references to it corrected
5992 * pcode.c: all pic16_pc_* hardware registers prefixed
5993 with underscore (_),
5994 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5995 * ralloc.c: newReg(): when register is REG_SFR then
5996 set address to rIdx,
5997 pic16_allocProcessorRegister(): marks register wasUsed=0
5998 pic16_writeUsedRegs(): added a call to assign processor
5999 registers via pic16_assignFixedRegisters
6001 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6003 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6004 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6005 variables in unused register banks. Also the SSEG is placed
6006 wherever there is enough space for it, and IDATA can be anywhere
6007 in internal RAM. For now compile using -Wl-Y[stack_size].
6008 The mem file is different for this option as well, since it
6009 makes no sense of talking about DSEG lenght.
6011 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6013 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6014 in certain cases, e.g. when ROM assignment, patch provided
6015 from Albert den Haan.
6017 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6158 xdata and data memory on startup. Set the environment variable
6159 SDCC_NOGENRAMCLEAR to disable this.
6160 * src/mcs51/peephole.def,
6161 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
6162 (allows non-interrupt and interrupt code to safely compete for a resource

7008 aren't part of the nRegs tally.
7010 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
7012 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

7018 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7019 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7020 fetching of the pointer
7021 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7022 copied from genNearPointerSet()
7023 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7024 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7025 If they pop r0/r1 they must be called in the opposite order than aopOp().
7026 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"

7038 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7040 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7041 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7042 type for bits was changed. It resulted in bit variables becoming
7043 global, which is not permitted in PIC 14 assembly output.
7045 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7060 A few small changes that speed up the peephole optimizer.
7064 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7066 Try to make the peephole optimizer smarter by maintaining
7067 an association between the assembly source code and the
7068 iCodes that originated them. Put this information to use
7069 with a new peephole rule condition "notVolatile" so that
7070 the rules can be aggressive yet still safe.
7075 * src/mcs51/peeph.def
7077 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7081 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7082 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7083 if the left or right operand symbols have the accuse flag set.
7085 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7087 Changed the type of the result of the ! (NOT) operator to char;
7088 previously it returned the same type as the source. This allows
7089 us to eliminate all the genFloatNot functions (all of its target
7090 implementations were very buggy) since !float can use the same
7093 * src/SDCCicode.c (ast2iCode): ! returns char

7100 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7102 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7103 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7104 during interrupts. Ensure WSAVE is located at a shared bank address.
7105 2. Fixed page selection in some places
7106 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7107 the registers name strings.
7108 4. Fixed "signed / unsigned compare" compiler warnings.
7109 5. The PIC port manages its own allocation of the general purpose
7110 registers, but makes no attempt to reuse them. As a result when
7111 compiling it soon runs out of general purpose registers. Some
7112 additional code was added to the files pcode.c and device.c to walk
7113 through the function call tree and rename the registers so that they
7123 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7124 genPlus() & genMinus() when the result is the same as left or right

7130 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7132 Made bitfield a distinct type from bit so that bitfields
7133 convert as per ANSI C and bits retain their traditional
7134 boolean style behaviour. Implemented bitfield support in
7142 * src/ds390/gen.c: bit v bitfield split
7143 * src/z80/gen.c: New support for bitfields
7144 * support/regression/tests/bitfields.c: reenabled z80,
7147 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7149 Rules 246.x, 247.x relate to bitfields, the others speed up
7150 access to xdata mapped I/O devices.
7152 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7154 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7156 Cleaned up genPackBits and genUnpackBits and added two helper
7157 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7158 for literal assignments in genPackBits (thanks to Frieder for
7164 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7166 Fixed bug #748310 (pointer to function type mishandled when the
7167 function name is omitted). Also fixed a SIGSEGV when a function
7168 attribute (reentrant, etc) is used on a non-function or on a
7169 function but misplaced before the parameter list.
7171 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7173 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7174 * support/Util/SDCCerr.h,
7175 * support/Util/SDCCerr.c: Added func attr misuse error msg
7177 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
7179 Fixed bug #787649 by anonymous
7180 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

7196 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7198 Made the constant following the "interrupt" keyword optional. If
7199 omitted, the function will not automatically be given an entry
7200 in the interrupt vector table (similar to #pragma NOIV, but
7201 less syntacticly kludgy). The interrupt number is also now
7202 range checked. Also fixed a bug in the high order bit example

7210 * support/Util/SDCCerr.h
7213 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
7215 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type

7731 * src/SDCCmain.c: linkOptions is changed to set *,
7732 added if/endif conditional macros to remove options help
7733 messages from optionsTable when a port is not configured, added
7734 support for the PIc16 port in the ports table, when executing
7735 the compiler with no port specified on command line, a default
7736 port is selected with the new macro DEFAULT_PORT which is
7737 defined in port.h, in setDefaultOptions() linkOptions is removed
7738 from initialization assignment, since now it is a set,
7739 parseCmdLine uses setParseWithComma for linkOptions, in
7740 linkEdit() linkOptions are accessed with new function indexSet()
7741 which returns the i'th item of a set variable. See SDCCset.c, in
7742 linkEdit() when calling buildCmdLine(), added linkOptions as
7743 last argument. Now users can pass arguments to gplink via the
7744 -Wl option, main() uses pic16glue() to glue up pic16 programs

7756 * src/pic16/glue.c: commented out some error producing lines
7757 * src/pic16/main.c: __config directives are commented out to stop
7758 gpasm complaining and test the linkage with gplink, _linkCmd and
7759 _asmCmd changed to be more gplink and gpasm friendly
7760 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7761 produced an error when parsed, peep rule 12 is added to utilize
7762 movff, but it is commented out since the pCode does not support
7763 yet a command with 2 address arguments
7765 2003-05-18 <johan AT balder>
7767 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8808 2003-01-04 <johan AT balder>
8810 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8812 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8813 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8815 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

8825 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8826 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8828 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8830 * in \sdcc\as\mcs51\ changed these files in order to create an
8831 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8832 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8833 following files to include the previous two files: aslink.dsp,
8834 Makefile.aslink, Makefile.bcc, and Makefile.in.
8836 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8837 .adb instead of .cdb
8839 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8841 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8842 value from option --iram-size.
8844 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8846 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8849 2002-09-18 <wiml AT hhhh.org>
8851 * SDCClrange.h: exposed setFromRange() and setToRange()
8852 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8853 packRegsForAccUse() (bug 542397)
8854 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8855 multiple times and emitting the fetch operations more than once
8856 added aopGetUsesAcc() function to allow binary operators to
8857 fetch their operands in the correct order; made genMinus() emit
8858 compact code for X = LITERAL - Y
8860 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8861 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8862 sprintf() in line 1267.
8864 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8865 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8868 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8869 Changes to aslink (All the changes are marked with 'JCF'):
8871 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8874 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8875 area BSEG. Also moves, if possible, the DATA area down into the internal
8876 ram so more space is available.
8878 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8881 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8882 not bytes. Function summary() which creates a memory usage summary
8883 file with extension .mem. Reports of overlaping stack and small stack
8884 size. If the space for the stack is less than 16 bytes aslink trows a
8887 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8888 the 8051. Option 'y' for memory summary output file.
8890 Changes to sdcc (All the changes are marked with 'JCF'):
8892 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8894 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8895 overlaying area for it (uses RegBankUsed[4]).
8897 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8898 bank zero as used by default. By default aslink locates the stack
8899 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8900 the creation of the .mem file. Delegates the allocation of data area
8901 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8902 the begining of the stack area to aslink.
8904 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8905 glue() in SDCCglue.c creates an area for it.
8907 2002-09-03 Borut Razem <borut.razem AT siol.net>
8908 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8909 sdcc/src/pic/glue.c:
8910 introduced atexit() handler for teporay files removal in case of
8911 errors, assertions, ...
8913 2002-08-29 Borut Razem <borut.razem AT siol.net>
8914 * sdcc/support/cpp2/auto-host_vc_in.h:
8915 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8916 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8917 Maybe there is a similar problem with BORLANDC? It should be checked!
8919 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8920 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8921 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8922 was not executed, and the compiler (cl) launched a warning:
8923 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8925 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8926 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8928 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8929 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8931 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8932 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8933 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8934 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8935 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8936 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8937 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8938 - added Release configuration in VS projects
8939 - review of compiler an linker options
8940 - VC .exe files are generated in bin_vc directory, not to interfere
8941 with binaries generated from other projects (cygwin, mingw, bcc ...)
8943 * sdcc/src/yacc.dsp: added
8945 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8946 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8947 and insert the version number definitions from .version
8949 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8951 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8952 added - genarate auto-host.h using auto-host_vc_in.h as template
8955 removed from CVS, generated automatically
8957 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8958 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8960 2002-08-11 Borut Razem <borut.razem AT siol.net>
8961 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8963 2002-08-10 Borut Razem <borut.razem AT siol.net>
8964 * src/SDCCmain.c (main):
8965 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8966 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8967 The consequence was that some temporary files were not removed.
8970 unification of code in functions tempfilename() and tempfile():
8971 function tempnam() is defined in Visual Studio 6.0 and .NET
8973 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8975 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8976 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8977 - removed compiler command line option /WX: Treats all warnings as errors
8978 - update a list of source files, included into the project
8980 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8981 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8982 changed project type to Generic Project so that can be correcly converted to VS.NET project
8984 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8986 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8988 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8990 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8991 added return 0 statements after assert() to make compiler happy
8993 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8994 added newline in the def file to keep MSC compiler satisfied
8996 * sdcc/src/z80/gen.c:
8997 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8998 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8999 - solved MSC error in function aopDump()
9001 * sdcc_vc.h: define PREFIX as "\\sdcc"
9003 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9004 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9010 singly-used registers optimized away)
9012 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9014 * 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.

9043 2002-03-28 Johan Knol <johan AT balder>
9045 * src/SDCCval.c: fixed bug #532436
9047 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9049 Added "char *Processor" field to the port structure.
9052 Added -p option. Allows port dependent processor to be specified.
9055 Initialized the new field char *Processor field to NULL in all ports
9058 Compiler generated registers for interrupt context saving
9059 were not getting allocated.
9061 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9064 Fixed left shift. Will promote the left side of a left shift
9065 if a) left shifting more than size of operand or b) when assigned
9066 to something size > size of left side
9068 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9070 tons of changes. Register allocation has been
9071 rewritten. Added customization for the various PICs. Flow
9072 analysis is restructured. ...
9078 Added. device.c is a PIC port hack to accomodate variations
9081 2002-03-13 Michael Hope <michaelh AT vroom>
9083 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9085 2002-03-04 johanknol <johanknol AT manik>
9087 * /src/SDCCval.c: fixed
9089 const unsigned char arr[][2] = { { 0, 1 } };

9092 2002-03-04 bela <bela AT manik>
9094 * /device/include/mcs51reg.h:
9095 ds89c420 register definition update
9097 2002-03-03 <johan AT FRIJA>
