1708 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1709 reserved identifier "__data".
1711 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1755 immedDom() returning wrong block; probably fixes bug #1160833)
1757 2005-03-20 Borut Razem <borut.razem AT siol.net>
1759 * support/scripts/inc2h.pl: WIN32 port

1763 * device/lib/makefile.in: added abs.c and labs.c
1765 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1767 * device/include/stdint.h: added
1768 * device/lib/abs.c: added
1769 * device/lib/labs.c: added
1770 * device/include/stdlib.h: added abs() and labs() prototypes

1785 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1787 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1789 * device/lib/printf_large.c: removed inline assembly for portability and
1790 readability. Use printf_fast if speed or size are more important.
1791 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1792 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1794 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1796 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1797 prevent compiler warning
1799 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1801 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1802 moved to level 0 and declared as static. Also they are explicit
1803 placed in access bank. This was necessery because some times they
1804 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1805 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1806 optimizations. Currently only compare to unsigned char is implemented,
1807 * src/pic16/gen.c: added fReturnIdx array,
1808 * (struct resolvedIfx) is moved to gen.h and made public,
1809 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1810 * (aopForSym): added an optimization to directly store in stack of
1811 the operand of a SEND iCode,
1812 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1813 but as registers instead (AOP_REG) using the fReturnIdx array,
1814 * (pic16_freeAsmop): remove the freed register from the
1815 _G.sregsAlloc field,
1816 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1817 a compare of 'WREG',
1818 * (pic16_popGetTempRegCond): changed function prototype, now
1819 function takes also a bitVector argument v which holds the current
1820 set of registers that are allocated for stack access by aopForSym,
1821 registers allocated in aopForSym for accessing stack symbols are not
1822 any more part of the functions usedRegs field,
1823 * (genCall): some times aopOp is called for a stack variable to be
1824 send, aopForSym might perform the push, if this is true make sure
1825 that genCall doesn't push the variable twice by testing _G.resDirect,
1826 * (genFunction): changed testing for unspecified interrupt number
1827 from 256 to INTNO_UNSPEC,
1828 * modified selection scheme of frame pointer generation. Previously
1829 if function did use local registers a frame pointer was generated,
1830 now a frame pointer is generated only if function has arguments
1831 (that need PLUSW2 register access), or has stack arguments, or the
1832 compiler is not instructed to omit the frame pointer,
1833 * (genEndFunction): before restoring local registers that were saved
1834 in the function preamble, also restore the registers that *might*
1835 have been allocated for stack access,
1836 * (genRet): removed some old comments,
1837 * (genCmp, the active (RN's) version): added a call to the
1838 pic16_genCmp_special function to perform the compare with a more
1839 robust and optimized way,
1840 * (genInline): a feature has been added in inline code generation,
1841 which allows a wildcard variable substitution when writing inline
1842 assembly. Code is incomplete and experimental therefore undocumented,
1843 * (genCast): changed order of aopOp for result and right to allow
1844 aopForSym to directly load the result if possible,
1845 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1846 perform an optimized compare on some selected special occasions,
1847 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1848 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1849 generate an IVT any more,
1850 * src/pic16/main.c (pic16_optionsTable): added command line option
1852 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1853 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1855 * src/pic16/NOTES: Raphael Neider added in list of active developers
1856 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1857 jumptable_end to prevent bug #,
1858 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1859 inCond and outCond fields,
1860 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1861 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1862 turn off register spilling,
1863 * (packRegsForOneUse): synced with other ports' versions although it
1864 is not used currently,
1865 * (pic16_packRegisters): added an optimization while reading
1866 structure bitfields, some registers may be saved (malloc code is
1867 decreased by 80 bytes)
1869 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1871 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1872 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1873 this can be optimized more?
1875 2005-03-10 Raphael Neider <rneider AT web.de>
1877 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1878 genNearPointerGet): (hopefully) fixed access to bitfields via
1879 pointers (p->bitN = x; and x = p->bitN; failed)
1881 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2513 Adding support for replacing ljmps with sjmps in jumptables
2514 generated for switch statements. For now you need to set the
2515 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2516 Now 4 algorithms for mcs51 jumptable generation are used:
2517 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2518 addresses loaded pc-relative for up to 112 cases and stack-pushing
2519 target addresses loaded with offset from dptr for up to 256 cases.

2549 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2551 * added libc directory. The current version of LibC contains string
2552 functions, ctype functions and macros and some functions of the
2553 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2554 be extensively tested in the future. Standard disclaimer here.
2555 Library is not automatically build yet. But one can build it by
2556 invoking 'make' inside the libc directory.
2557 * added ADC library under libio. Preliminary version yet.

2566 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2567 * (pic16_storeForReturn): optimized return of 0,
2568 * (genCmp): experimental code for new genCmp which uses PIC18's
2569 special compare&skip instructions. Initial tests fail some times
2570 with variables grater than 1 byte in size, so new code is disabled,
2571 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2573 * (genCast): began a fix to optimize the casting of a bit to another
2574 bit, now assigning a bitfield to another bitfield will fail, sorry,
2575 * src/pic16/main.c: disabled the use of lr-support feature,
2576 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2579 bits with offset (case PO_GPR_BIT),
2580 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
2582 * (isBankInstruction): modified to return 0 for no banking instruction,
2583 and 1 for banking instruction,
2584 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,

5597 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5599 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5600 loaded with the linker search paths (-L arguments) and the libraries
5601 to be linked with the current source (-l arguments). Changes
5602 currently will affect only the pic16 port.
5603 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5604 include path the port specific paths and port specific libraries,
5605 * gplink command now contains the $3 argument,
5606 * src/pic16/device.h,
5607 * src/pic16/device.c,: structure PIC_device is made public and
5608 renamed to PIC16_device, the same for variable Pics which is renamed

5623 Documenting changes from previous commits.
5624 * configure.in (version 1.56),
5625 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5626 when generating output files to configure the pic16 library,
5627 but now I've commented it out, since gputils aren't installed in the
5628 SF compile farm, so library won't compile
5630 * device/lib/Makefile.in (version 1.56): initially I've added in
5631 target 'all' the prerequestive 'model-pic16' so it compiled the
5632 pic16 library, but now I've commented it out for the same reasons
5634 * added targets 'model-pic16' and 'objects-pic16' to compile the
5636 * added target 'port-specific-objects-pic16' to handle the
5637 generated libraries and copy them into the build/ directory
5638 * added target 'clean-intermediate-pic16' to clean intermediate
5639 files into pic16 directory
5640 * in target 'installdirs' added line to create directory pic16 in
5641 the installation path
5643 * device/include/Makefile.in (version 1.11): in target 'install'
5644 added lines to copy all header files to installation path,
5645 * in target 'installdirs' added line create directory for pic16
5646 headers in the installation path

5662 option so that it actually works. Made it specific to the z80, since
5663 the gbz80 doesn't have these kinds of I/O ports.
5665 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5667 * device/include/z180.h,

5696 weren't marked as being in the access bank,
5698 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5700 Added portion of GNU PIC Library under the directory
5701 device/include/pic16 and device/lib/pic16. These files
5702 contain the declarations of SFRs for the PIC18Fxx2 devices.
5703 The directory is initialized via configure from toplevel.
5705 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

5733 all over. Telling LaTeX to be less strict with word spacing
5734 to better keep the right margin. Changed some notes about
5735 maintainance of the ports in section 3.2.1 - is it OK like this?
5737 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5777 * src/pic16/peeph.def: all peepholes with movff are commented out,
5778 because there is a problem in the pcode peep optimizer,
5779 * src/pic16/ralloc.c: the register allocator can now reuse local

5856 2004-01-07 Borut Razem <borut.razem AT siol.net>
5858 * support/scripts/sdcc.nsi: update PATH
5859 * support/scripts/sdcc.ico: craeted

5872 include information about variables allocated to the overlay
5875 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5877 * as/mcs51/lkmain.c: Help about -Y option

5889 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5891 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5892 (default behaviour).
5894 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5896 A python script to validate compiler diagnostic messages. It can be
5897 used to verify that sdcc complains about bad c source code and
5898 gives a good location of the error.
5899 * support/valdiag/Makefile,
5900 * support/valdiag/valdiag.py,
5901 * support/valdiag/tests/*
5903 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5916 * src/common.h: added ifndef/define/endif macros
5917 around the header file.
5918 Bug reported from Jesus Calvino-Fraga
5920 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5922 * sdcc.spec: updated
5923 * device/include/Makefile.in: don't install CVS directories
5924 * device/lib/Makefile.in: added removal of CVS directories after install
5925 * doc/Makefile: fixed install, added local_icons
5926 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5927 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5928 * src/ds390/gen.c (genRightShift): fixed bug #870788
5929 * src/SDCCast.c (decorateType): fixed bug #870781
5931 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5933 PIC16 port related changes:
5934 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5935 added variable stackPos,
5937 * gen.c: genCall, assignResultValue: added support for
5938 pushing/retrieving function parameters to/from stack,
5939 genFunction,genEndFunction: setup stack frame for the
5941 genAddrOf: will be changed according to bug 863624
5943 * added files genutils.c and genutils.h which contain gen*
5944 debugged and optimised functions extracted from gen.c
5946 * glue.c: added variable 'externs' which holds extern symbols,
5947 pic16emitRegularMap: is modified to properly handle relocatable
5948 symbols under the new scheme,
5949 pic16createInterruptVect: is modified
5950 pic16printPublics: is modified to emit 'global' assembler directives,
5951 added pic16_printExterns to print extern symbols,
5952 pic16glue: initializes stack/frame pointer in the beginning of
5953 the assembly output. Temporary hack, will be corrected later,
5954 because gplink yet does not support stack and SDCC does not
5955 yet support a type of crt0.o object to create the final binary.
5957 * Removed many lines that contain 8051 legacy code.
5958 * The code is finally placed under a 'code' directive.
5959 * Added port specific options.
5961 * _process_pragma: simplified since now we do not need *special*
5962 include file to define SFR registers. But a separate header
5963 will be needed. This will be developed later.
5964 * _pic16_parseOptions: added, parses port specific options:
5965 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5966 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5967 --preplace-udata-with=
5969 * _pic16_setDefaultOptions: modified to initialize section names,
5970 but hack is temporarly out of order since it needs improvement.
5971 * _pic16_genAssemblerPreamble: configuration words are emitted by
5972 their address instead of their name. This part is incomplete and
5973 supports only the 18Fxx2 devices. Other devices will emit an error
5974 during assembly since they do not contain the same set of config
5976 * _pic16_genIVT: is modified,
5978 * pcode.c: added definitions for some hardware registers that are needed
5980 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5981 All PCI entries are updated. Now LFSR is supported.
5982 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5983 * added pic16_newpCodeOpLit2 to support instructions with
5984 two literal arguments
5985 * pic16_pCode2str: corrected code that emits assembler instructions
5986 with two literal operands and those that have an access bit modifier
5987 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5988 this fixes a bug which caused some labels to be lost, when an
5989 assembler directive was added, i.e. banksel,
5990 * pic16_FixRegisterBanking: improved logic that causes the insertion
5992 * InlineFunction: functions that are called once, are not any more
5993 inlined. This can be a port option in the future,
5995 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5997 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5998 hold the corresponding uninitialized symbols,
5999 * pic16_allocProcessorRegister: registers have explicit marked the
6001 * pic16_allocInternalRegister: registers are explicit marked as
6003 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6004 processing list, so bit registers were lost,
6007 * ralloc.h: added field 'accessBank' and original symbol operand
6008 in register definition,
6009 * removed the field isMapped from register definition,
6011 ** Several functions have been removed from various sources:
6012 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6013 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6014 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6015 pic16_assignRelocatableRegisters
6017 ** others have been introduced:
6018 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6019 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6021 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6023 * support/scripts/inc2h.pl: changed definition of BIT_AT
6024 to emit 'sbit at' instead of 'bit at'. This was a request.
6026 PIC16 port related preliminary changes:
6027 * gen.c: prefixed function popRegFromString with
6028 pic16_ and all references to it corrected
6029 * pcode.c: all pic16_pc_* hardware registers prefixed
6030 with underscore (_),
6031 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6032 * ralloc.c: newReg(): when register is REG_SFR then
6033 set address to rIdx,
6034 pic16_allocProcessorRegister(): marks register wasUsed=0
6035 pic16_writeUsedRegs(): added a call to assign processor
6036 registers via pic16_assignFixedRegisters
6038 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6040 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6041 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6042 variables in unused register banks. Also the SSEG is placed
6043 wherever there is enough space for it, and IDATA can be anywhere
6044 in internal RAM. For now compile using -Wl-Y[stack_size].
6045 The mem file is different for this option as well, since it
6046 makes no sense of talking about DSEG lenght.
6048 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6050 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6051 in certain cases, e.g. when ROM assignment, patch provided
6052 from Albert den Haan.
6054 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6196 SDCC_NOGENRAMCLEAR to disable this.
6197 * src/mcs51/peephole.def,
6198 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
6199 (allows non-interrupt and interrupt code to safely compete for a resource
6200 without the non-interrupt code having to disable interrupts)
6202 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6204 * src/SDCCicode.c (geniCodeAdd),

6224 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6226 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165
6228 2003-12-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6296 revision 1.188 (access to fields of a structure at an absolute address);
6297 it breaks with bitfields, extern declarations, and gcse analysis.
6298 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6299 could be assigned through a pointer, so don't complain.

7077 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7078 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7079 type for bits was changed. It resulted in bit variables becoming

7097 A few small changes that speed up the peephole optimizer.
7101 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7103 Try to make the peephole optimizer smarter by maintaining
7104 an association between the assembly source code and the
7105 iCodes that originated them. Put this information to use
7106 with a new peephole rule condition "notVolatile" so that
7107 the rules can be aggressive yet still safe.
7112 * src/mcs51/peeph.def
7114 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7118 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7119 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7120 if the left or right operand symbols have the accuse flag set.
7122 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7124 Changed the type of the result of the ! (NOT) operator to char;
7125 previously it returned the same type as the source. This allows
7126 us to eliminate all the genFloatNot functions (all of its target
7127 implementations were very buggy) since !float can use the same
7130 * src/SDCCicode.c (ast2iCode): ! returns char

7139 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7140 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7141 during interrupts. Ensure WSAVE is located at a shared bank address.
7142 2. Fixed page selection in some places
7143 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7144 the registers name strings.
7145 4. Fixed "signed / unsigned compare" compiler warnings.
7146 5. The PIC port manages its own allocation of the general purpose
7147 registers, but makes no attempt to reuse them. As a result when
7148 compiling it soon runs out of general purpose registers. Some
7149 additional code was added to the files pcode.c and device.c to walk
7150 through the function call tree and rename the registers so that they
7160 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7161 genPlus() & genMinus() when the result is the same as left or right

7167 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7169 Made bitfield a distinct type from bit so that bitfields
7170 convert as per ANSI C and bits retain their traditional
7171 boolean style behaviour. Implemented bitfield support in
7179 * src/ds390/gen.c: bit v bitfield split
7180 * src/z80/gen.c: New support for bitfields
7181 * support/regression/tests/bitfields.c: reenabled z80,
7184 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7186 Rules 246.x, 247.x relate to bitfields, the others speed up
7187 access to xdata mapped I/O devices.
7189 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7191 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7193 Cleaned up genPackBits and genUnpackBits and added two helper
7194 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7195 for literal assignments in genPackBits (thanks to Frieder for
7201 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7203 Fixed bug #748310 (pointer to function type mishandled when the
7204 function name is omitted). Also fixed a SIGSEGV when a function
7205 attribute (reentrant, etc) is used on a non-function or on a

7775 from initialization assignment, since now it is a set,
7776 parseCmdLine uses setParseWithComma for linkOptions, in
7777 linkEdit() linkOptions are accessed with new function indexSet()
7778 which returns the i'th item of a set variable. See SDCCset.c, in
7779 linkEdit() when calling buildCmdLine(), added linkOptions as
7780 last argument. Now users can pass arguments to gplink via the
7781 -Wl option, main() uses pic16glue() to glue up pic16 programs

7795 gpasm complaining and test the linkage with gplink, _linkCmd and
7796 _asmCmd changed to be more gplink and gpasm friendly
7797 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7798 produced an error when parsed, peep rule 12 is added to utilize
7799 movff, but it is commented out since the pCode does not support
7800 yet a command with 2 address arguments

8822 2003-01-07 <johan AT balder>
8824 * src/SDCCast.c (decorateType): fixed bug #600035

8839 * src/SDCCicode.c: fixed array add
8841 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8842 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8843 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8845 2003-01-04 <johan AT balder>
8847 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8849 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8850 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8852 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8853 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8862 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8863 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8865 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8867 * in \sdcc\as\mcs51\ changed these files in order to create an
8868 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8869 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8870 following files to include the previous two files: aslink.dsp,
8871 Makefile.aslink, Makefile.bcc, and Makefile.in.
8873 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8874 .adb instead of .cdb
8876 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8878 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8879 value from option --iram-size.
8881 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8883 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8886 2002-09-18 <wiml AT hhhh.org>
8888 * SDCClrange.h: exposed setFromRange() and setToRange()
8889 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8890 packRegsForAccUse() (bug 542397)
8891 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8892 multiple times and emitting the fetch operations more than once
8893 added aopGetUsesAcc() function to allow binary operators to
8894 fetch their operands in the correct order; made genMinus() emit
8895 compact code for X = LITERAL - Y
8897 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8898 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8899 sprintf() in line 1267.
8901 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8902 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8905 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8906 Changes to aslink (All the changes are marked with 'JCF'):
8908 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8911 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8912 area BSEG. Also moves, if possible, the DATA area down into the internal
8913 ram so more space is available.
8915 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8918 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8919 not bytes. Function summary() which creates a memory usage summary
8920 file with extension .mem. Reports of overlaping stack and small stack
8921 size. If the space for the stack is less than 16 bytes aslink trows a
8924 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8925 the 8051. Option 'y' for memory summary output file.
8927 Changes to sdcc (All the changes are marked with 'JCF'):
8929 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8931 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8932 overlaying area for it (uses RegBankUsed[4]).
8934 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8935 bank zero as used by default. By default aslink locates the stack
8936 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8937 the creation of the .mem file. Delegates the allocation of data area
8938 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8939 the begining of the stack area to aslink.
8941 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8942 glue() in SDCCglue.c creates an area for it.
8944 2002-09-03 Borut Razem <borut.razem AT siol.net>
8945 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8946 sdcc/src/pic/glue.c:
8947 introduced atexit() handler for teporay files removal in case of
8948 errors, assertions, ...
8950 2002-08-29 Borut Razem <borut.razem AT siol.net>
8951 * sdcc/support/cpp2/auto-host_vc_in.h:
8952 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8953 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8954 Maybe there is a similar problem with BORLANDC? It should be checked!
8956 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8957 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8958 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8959 was not executed, and the compiler (cl) launched a warning:
8960 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8962 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8963 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8965 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8966 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8968 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8969 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8970 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8971 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8972 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8973 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8974 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8975 - added Release configuration in VS projects
8976 - review of compiler an linker options
8977 - VC .exe files are generated in bin_vc directory, not to interfere
8978 with binaries generated from other projects (cygwin, mingw, bcc ...)
8980 * sdcc/src/yacc.dsp: added
8982 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8983 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8984 and insert the version number definitions from .version
8986 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8988 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8989 added - genarate auto-host.h using auto-host_vc_in.h as template
8992 removed from CVS, generated automatically
8994 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8995 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8997 2002-08-11 Borut Razem <borut.razem AT siol.net>
8998 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9000 2002-08-10 Borut Razem <borut.razem AT siol.net>
9001 * src/SDCCmain.c (main):
9002 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9003 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9004 The consequence was that some temporary files were not removed.
9007 unification of code in functions tempfilename() and tempfile():
9008 function tempnam() is defined in Visual Studio 6.0 and .NET
9010 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9012 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9013 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9014 - removed compiler command line option /WX: Treats all warnings as errors
9015 - update a list of source files, included into the project
9017 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9018 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9019 changed project type to Generic Project so that can be correcly converted to VS.NET project
9021 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9023 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9025 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9027 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9028 added return 0 statements after assert() to make compiler happy
9030 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9031 added newline in the def file to keep MSC compiler satisfied
9033 * sdcc/src/z80/gen.c:
9034 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9035 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9036 - solved MSC error in function aopDump()
9038 * sdcc_vc.h: define PREFIX as "\\sdcc"
9040 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9041 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9043 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9044 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9045 - Rewrote the register banking algorithm.
9046 - Added pCode live-range analysis to registers (for now, only non-used and
9047 singly-used registers optimized away)
9049 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9051 * 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.
9053 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9054 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9056 2002-04-22 Michael Hope <michaelh AT vroom>
9058 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.

9072 * src/z80/peeph.def: Added transpose redundent load rule.
9074 * src/z80/main.c: Added force callee saves for jaune.
9076 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9078 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9080 2002-03-28 Johan Knol <johan AT balder>
9082 * src/SDCCval.c: fixed bug #532436
9084 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9086 Added "char *Processor" field to the port structure.
