1710 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1711 always available in leading double underscore form. The C99 support is
1712 mostly missing, but it's a start.
1713 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1714 reserved identifier "__data".
1716 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1759 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
1760 immedDom() returning wrong block; probably fixes bug #1160833)
1762 2005-03-20 Borut Razem <borut.razem AT siol.net>
1764 * support/scripts/inc2h.pl: WIN32 port
1766 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1768 * device/lib/makefile.in: added abs.c and labs.c
1770 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1772 * device/include/stdint.h: added
1773 * device/lib/abs.c: added
1774 * device/lib/labs.c: added
1775 * device/include/stdlib.h: added abs() and labs() prototypes

1782 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1784 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed

1790 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1792 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1794 * device/lib/printf_large.c: removed inline assembly for portability and
1795 readability. Use printf_fast if speed or size are more important.
1796 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1797 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1799 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1801 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1802 prevent compiler warning
1804 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1806 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1807 moved to level 0 and declared as static. Also they are explicit
1808 placed in access bank. This was necessery because some times they
1809 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1810 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1811 optimizations. Currently only compare to unsigned char is implemented,
1812 * src/pic16/gen.c: added fReturnIdx array,
1813 * (struct resolvedIfx) is moved to gen.h and made public,
1814 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1815 * (aopForSym): added an optimization to directly store in stack of
1816 the operand of a SEND iCode,
1817 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1818 but as registers instead (AOP_REG) using the fReturnIdx array,
1819 * (pic16_freeAsmop): remove the freed register from the
1820 _G.sregsAlloc field,
1821 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1822 a compare of 'WREG',
1823 * (pic16_popGetTempRegCond): changed function prototype, now
1824 function takes also a bitVector argument v which holds the current
1825 set of registers that are allocated for stack access by aopForSym,
1826 registers allocated in aopForSym for accessing stack symbols are not
1827 any more part of the functions usedRegs field,
1828 * (genCall): some times aopOp is called for a stack variable to be
1829 send, aopForSym might perform the push, if this is true make sure
1830 that genCall doesn't push the variable twice by testing _G.resDirect,
1831 * (genFunction): changed testing for unspecified interrupt number
1832 from 256 to INTNO_UNSPEC,
1833 * modified selection scheme of frame pointer generation. Previously
1834 if function did use local registers a frame pointer was generated,
1835 now a frame pointer is generated only if function has arguments
1836 (that need PLUSW2 register access), or has stack arguments, or the
1837 compiler is not instructed to omit the frame pointer,
1838 * (genEndFunction): before restoring local registers that were saved
1839 in the function preamble, also restore the registers that *might*
1840 have been allocated for stack access,
1841 * (genRet): removed some old comments,
1842 * (genCmp, the active (RN's) version): added a call to the
1843 pic16_genCmp_special function to perform the compare with a more
1844 robust and optimized way,
1845 * (genInline): a feature has been added in inline code generation,
1846 which allows a wildcard variable substitution when writing inline
1847 assembly. Code is incomplete and experimental therefore undocumented,
1848 * (genCast): changed order of aopOp for result and right to allow
1849 aopForSym to directly load the result if possible,
1850 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1851 perform an optimized compare on some selected special occasions,
1852 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1853 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1854 generate an IVT any more,
1855 * src/pic16/main.c (pic16_optionsTable): added command line option
1857 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1858 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1860 * src/pic16/NOTES: Raphael Neider added in list of active developers
1861 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1862 jumptable_end to prevent bug #,
1863 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1864 inCond and outCond fields,
1865 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1866 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1867 turn off register spilling,
1868 * (packRegsForOneUse): synced with other ports' versions although it
1869 is not used currently,
1870 * (pic16_packRegisters): added an optimization while reading
1871 structure bitfields, some registers may be saved (malloc code is
1872 decreased by 80 bytes)
1874 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1876 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1877 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1878 this can be optimized more?
1880 2005-03-10 Raphael Neider <rneider AT web.de>
1882 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1883 genNearPointerGet): (hopefully) fixed access to bitfields via
1884 pointers (p->bitN = x; and x = p->bitN; failed)

2074 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2075 this might fix SIGSEGVs on MinGW...
2076 * src/SDCCopt.c (killDeadCode): restored original behaviour
2077 (volatile operands might get thrown away though)
2079 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2518 Adding support for replacing ljmps with sjmps in jumptables
2519 generated for switch statements. For now you need to set the
2520 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2521 Now 4 algorithms for mcs51 jumptable generation are used:
2522 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2523 addresses loaded pc-relative for up to 112 cases and stack-pushing
2524 target addresses loaded with offset from dptr for up to 256 cases.

2552 to call when a stack overflow occurs,
2553 * (malloc.h): added CVS Id tag,
2554 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2556 * added libc directory. The current version of LibC contains string
2557 functions, ctype functions and macros and some functions of the
2558 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2559 be extensively tested in the future. Standard disclaimer here.
2560 Library is not automatically build yet. But one can build it by
2561 invoking 'make' inside the libc directory.

2571 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2572 * (pic16_storeForReturn): optimized return of 0,
2573 * (genCmp): experimental code for new genCmp which uses PIC18's
2574 special compare&skip instructions. Initial tests fail some times
2575 with variables grater than 1 byte in size, so new code is disabled,
2576 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2578 * (genCast): began a fix to optimize the casting of a bit to another
2579 bit, now assigning a bitfield to another bitfield will fail, sorry,
2580 * src/pic16/main.c: disabled the use of lr-support feature,
2581 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5602 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5604 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5605 loaded with the linker search paths (-L arguments) and the libraries
5606 to be linked with the current source (-l arguments). Changes
5607 currently will affect only the pic16 port.
5608 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5609 include path the port specific paths and port specific libraries,
5610 * gplink command now contains the $3 argument,
5611 * src/pic16/device.h,
5612 * src/pic16/device.c,: structure PIC_device is made public and
5613 renamed to PIC16_device, the same for variable Pics which is renamed

5628 Documenting changes from previous commits.
5629 * configure.in (version 1.56),
5630 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5631 when generating output files to configure the pic16 library,
5632 but now I've commented it out, since gputils aren't installed in the
5633 SF compile farm, so library won't compile
5635 * device/lib/Makefile.in (version 1.56): initially I've added in
5636 target 'all' the prerequestive 'model-pic16' so it compiled the
5637 pic16 library, but now I've commented it out for the same reasons
5639 * added targets 'model-pic16' and 'objects-pic16' to compile the
5641 * added target 'port-specific-objects-pic16' to handle the
5642 generated libraries and copy them into the build/ directory
5643 * added target 'clean-intermediate-pic16' to clean intermediate
5644 files into pic16 directory
5645 * in target 'installdirs' added line to create directory pic16 in
5646 the installation path
5648 * device/include/Makefile.in (version 1.11): in target 'install'
5649 added lines to copy all header files to installation path,
5650 * in target 'installdirs' added line create directory for pic16
5651 headers in the installation path

5667 option so that it actually works. Made it specific to the z80, since
5668 the gbz80 doesn't have these kinds of I/O ports.
5670 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5672 * device/include/z180.h,

5701 weren't marked as being in the access bank,
5703 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5705 Added portion of GNU PIC Library under the directory
5706 device/include/pic16 and device/lib/pic16. These files
5707 contain the declarations of SFRs for the PIC18Fxx2 devices.
5708 The directory is initialized via configure from toplevel.
5710 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

5738 all over. Telling LaTeX to be less strict with word spacing
5739 to better keep the right margin. Changed some notes about
5740 maintainance of the ports in section 3.2.1 - is it OK like this?
5742 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5782 * src/pic16/peeph.def: all peepholes with movff are commented out,
5783 because there is a problem in the pcode peep optimizer,
5784 * src/pic16/ralloc.c: the register allocator can now reuse local

5877 include information about variables allocated to the overlay
5880 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5882 * as/mcs51/lkmain.c: Help about -Y option

5894 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5896 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5897 (default behaviour).
5899 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5901 A python script to validate compiler diagnostic messages. It can be
5902 used to verify that sdcc complains about bad c source code and
5903 gives a good location of the error.
5904 * support/valdiag/Makefile,
5905 * support/valdiag/valdiag.py,
5906 * support/valdiag/tests/*
5908 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5921 * src/common.h: added ifndef/define/endif macros
5922 around the header file.
5923 Bug reported from Jesus Calvino-Fraga
5925 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5927 * sdcc.spec: updated
5928 * device/include/Makefile.in: don't install CVS directories
5929 * device/lib/Makefile.in: added removal of CVS directories after install
5930 * doc/Makefile: fixed install, added local_icons
5931 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5932 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5933 * src/ds390/gen.c (genRightShift): fixed bug #870788
5934 * src/SDCCast.c (decorateType): fixed bug #870781
5936 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5938 PIC16 port related changes:
5939 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5940 added variable stackPos,
5942 * gen.c: genCall, assignResultValue: added support for
5943 pushing/retrieving function parameters to/from stack,
5944 genFunction,genEndFunction: setup stack frame for the
5946 genAddrOf: will be changed according to bug 863624
5948 * added files genutils.c and genutils.h which contain gen*
5949 debugged and optimised functions extracted from gen.c
5951 * glue.c: added variable 'externs' which holds extern symbols,
5952 pic16emitRegularMap: is modified to properly handle relocatable
5953 symbols under the new scheme,
5954 pic16createInterruptVect: is modified
5955 pic16printPublics: is modified to emit 'global' assembler directives,
5956 added pic16_printExterns to print extern symbols,
5957 pic16glue: initializes stack/frame pointer in the beginning of
5958 the assembly output. Temporary hack, will be corrected later,
5959 because gplink yet does not support stack and SDCC does not
5960 yet support a type of crt0.o object to create the final binary.
5962 * Removed many lines that contain 8051 legacy code.
5963 * The code is finally placed under a 'code' directive.
5964 * Added port specific options.
5966 * _process_pragma: simplified since now we do not need *special*
5967 include file to define SFR registers. But a separate header
5968 will be needed. This will be developed later.
5969 * _pic16_parseOptions: added, parses port specific options:
5970 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5971 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5972 --preplace-udata-with=
5974 * _pic16_setDefaultOptions: modified to initialize section names,
5975 but hack is temporarly out of order since it needs improvement.
5976 * _pic16_genAssemblerPreamble: configuration words are emitted by
5977 their address instead of their name. This part is incomplete and
5978 supports only the 18Fxx2 devices. Other devices will emit an error
5979 during assembly since they do not contain the same set of config
5981 * _pic16_genIVT: is modified,
5983 * pcode.c: added definitions for some hardware registers that are needed
5985 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5986 All PCI entries are updated. Now LFSR is supported.
5987 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5988 * added pic16_newpCodeOpLit2 to support instructions with
5989 two literal arguments
5990 * pic16_pCode2str: corrected code that emits assembler instructions
5991 with two literal operands and those that have an access bit modifier
5992 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5993 this fixes a bug which caused some labels to be lost, when an
5994 assembler directive was added, i.e. banksel,
5995 * pic16_FixRegisterBanking: improved logic that causes the insertion
5997 * InlineFunction: functions that are called once, are not any more
5998 inlined. This can be a port option in the future,
6000 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6002 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6003 hold the corresponding uninitialized symbols,
6004 * pic16_allocProcessorRegister: registers have explicit marked the
6006 * pic16_allocInternalRegister: registers are explicit marked as
6008 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6009 processing list, so bit registers were lost,
6012 * ralloc.h: added field 'accessBank' and original symbol operand
6013 in register definition,
6014 * removed the field isMapped from register definition,
6016 ** Several functions have been removed from various sources:
6017 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6018 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6019 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6020 pic16_assignRelocatableRegisters
6022 ** others have been introduced:
6023 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6024 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6026 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6028 * support/scripts/inc2h.pl: changed definition of BIT_AT
6029 to emit 'sbit at' instead of 'bit at'. This was a request.
6031 PIC16 port related preliminary changes:
6032 * gen.c: prefixed function popRegFromString with
6033 pic16_ and all references to it corrected
6034 * pcode.c: all pic16_pc_* hardware registers prefixed
6035 with underscore (_),
6036 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6037 * ralloc.c: newReg(): when register is REG_SFR then
6038 set address to rIdx,
6039 pic16_allocProcessorRegister(): marks register wasUsed=0
6040 pic16_writeUsedRegs(): added a call to assign processor
6041 registers via pic16_assignFixedRegisters
6043 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6045 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6046 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6047 variables in unused register banks. Also the SSEG is placed
6048 wherever there is enough space for it, and IDATA can be anywhere
6049 in internal RAM. For now compile using -Wl-Y[stack_size].
6050 The mem file is different for this option as well, since it
6051 makes no sense of talking about DSEG lenght.
6053 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6055 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6056 in certain cases, e.g. when ROM assignment, patch provided
6057 from Albert den Haan.
6059 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6201 SDCC_NOGENRAMCLEAR to disable this.
6202 * src/mcs51/peephole.def,
6203 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
6204 (allows non-interrupt and interrupt code to safely compete for a resource
6205 without the non-interrupt code having to disable interrupts)
6207 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6209 * src/SDCCicode.c (geniCodeAdd),

6229 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6231 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165
6233 2003-12-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6301 revision 1.188 (access to fields of a structure at an absolute address);
6302 it breaks with bitfields, extern declarations, and gcse analysis.
6303 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6304 could be assigned through a pointer, so don't complain.

7082 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7083 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7084 type for bits was changed. It resulted in bit variables becoming
7085 global, which is not permitted in PIC 14 assembly output.

7102 A few small changes that speed up the peephole optimizer.
7106 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7108 Try to make the peephole optimizer smarter by maintaining
7109 an association between the assembly source code and the
7110 iCodes that originated them. Put this information to use
7111 with a new peephole rule condition "notVolatile" so that
7112 the rules can be aggressive yet still safe.
7117 * src/mcs51/peeph.def
7119 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7123 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7124 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7125 if the left or right operand symbols have the accuse flag set.
7127 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7129 Changed the type of the result of the ! (NOT) operator to char;
7130 previously it returned the same type as the source. This allows
7131 us to eliminate all the genFloatNot functions (all of its target
7132 implementations were very buggy) since !float can use the same
7135 * src/SDCCicode.c (ast2iCode): ! returns char

7144 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7145 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7146 during interrupts. Ensure WSAVE is located at a shared bank address.
7147 2. Fixed page selection in some places
7148 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7149 the registers name strings.
7150 4. Fixed "signed / unsigned compare" compiler warnings.
7151 5. The PIC port manages its own allocation of the general purpose
7152 registers, but makes no attempt to reuse them. As a result when
7153 compiling it soon runs out of general purpose registers. Some
7154 additional code was added to the files pcode.c and device.c to walk
7155 through the function call tree and rename the registers so that they
7165 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7166 genPlus() & genMinus() when the result is the same as left or right
7168 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7172 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7174 Made bitfield a distinct type from bit so that bitfields
7175 convert as per ANSI C and bits retain their traditional
7176 boolean style behaviour. Implemented bitfield support in
7184 * src/ds390/gen.c: bit v bitfield split
7185 * src/z80/gen.c: New support for bitfields
7186 * support/regression/tests/bitfields.c: reenabled z80,
7189 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7191 Rules 246.x, 247.x relate to bitfields, the others speed up
7192 access to xdata mapped I/O devices.
7194 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7196 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7198 Cleaned up genPackBits and genUnpackBits and added two helper
7199 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7200 for literal assignments in genPackBits (thanks to Frieder for
7206 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7208 Fixed bug #748310 (pointer to function type mishandled when the
7209 function name is omitted). Also fixed a SIGSEGV when a function
7210 attribute (reentrant, etc) is used on a non-function or on a

7241 omitted, the function will not automatically be given an entry
7242 in the interrupt vector table (similar to #pragma NOIV, but

7780 from initialization assignment, since now it is a set,
7781 parseCmdLine uses setParseWithComma for linkOptions, in
7782 linkEdit() linkOptions are accessed with new function indexSet()
7783 which returns the i'th item of a set variable. See SDCCset.c, in
7784 linkEdit() when calling buildCmdLine(), added linkOptions as
7785 last argument. Now users can pass arguments to gplink via the
7786 -Wl option, main() uses pic16glue() to glue up pic16 programs

7800 gpasm complaining and test the linkage with gplink, _linkCmd and
7801 _asmCmd changed to be more gplink and gpasm friendly
7802 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7803 produced an error when parsed, peep rule 12 is added to utilize
7804 movff, but it is commented out since the pCode does not support
7805 yet a command with 2 address arguments

8844 * src/SDCCicode.c: fixed array add
8846 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8847 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8848 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8850 2003-01-04 <johan AT balder>
8852 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8854 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8855 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8857 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8858 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8864 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
8865 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8867 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8868 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8870 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8872 * in \sdcc\as\mcs51\ changed these files in order to create an
8873 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8874 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8875 following files to include the previous two files: aslink.dsp,
8876 Makefile.aslink, Makefile.bcc, and Makefile.in.
8878 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8879 .adb instead of .cdb
8881 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8883 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8884 value from option --iram-size.
8886 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8888 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8891 2002-09-18 <wiml AT hhhh.org>
8893 * SDCClrange.h: exposed setFromRange() and setToRange()
8894 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8895 packRegsForAccUse() (bug 542397)
8896 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8897 multiple times and emitting the fetch operations more than once
8898 added aopGetUsesAcc() function to allow binary operators to
8899 fetch their operands in the correct order; made genMinus() emit
8900 compact code for X = LITERAL - Y
8902 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8903 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8904 sprintf() in line 1267.
8906 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8907 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8910 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8911 Changes to aslink (All the changes are marked with 'JCF'):
8913 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8916 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8917 area BSEG. Also moves, if possible, the DATA area down into the internal
8918 ram so more space is available.
8920 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8923 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8924 not bytes. Function summary() which creates a memory usage summary
8925 file with extension .mem. Reports of overlaping stack and small stack
8926 size. If the space for the stack is less than 16 bytes aslink trows a
8929 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8930 the 8051. Option 'y' for memory summary output file.
8932 Changes to sdcc (All the changes are marked with 'JCF'):
8934 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8936 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8937 overlaying area for it (uses RegBankUsed[4]).
8939 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8940 bank zero as used by default. By default aslink locates the stack
8941 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8942 the creation of the .mem file. Delegates the allocation of data area
8943 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8944 the begining of the stack area to aslink.
8946 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8947 glue() in SDCCglue.c creates an area for it.
8949 2002-09-03 Borut Razem <borut.razem AT siol.net>
8950 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8951 sdcc/src/pic/glue.c:
8952 introduced atexit() handler for teporay files removal in case of
8953 errors, assertions, ...
8955 2002-08-29 Borut Razem <borut.razem AT siol.net>
8956 * sdcc/support/cpp2/auto-host_vc_in.h:
8957 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8958 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8959 Maybe there is a similar problem with BORLANDC? It should be checked!
8961 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8962 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8963 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8964 was not executed, and the compiler (cl) launched a warning:
8965 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8967 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8968 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8970 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8971 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8973 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8974 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8975 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8976 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8977 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8978 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8979 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8980 - added Release configuration in VS projects
8981 - review of compiler an linker options
8982 - VC .exe files are generated in bin_vc directory, not to interfere
8983 with binaries generated from other projects (cygwin, mingw, bcc ...)
8985 * sdcc/src/yacc.dsp: added
8987 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8988 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8989 and insert the version number definitions from .version
8991 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8993 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8994 added - genarate auto-host.h using auto-host_vc_in.h as template
8997 removed from CVS, generated automatically
8999 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9000 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9002 2002-08-11 Borut Razem <borut.razem AT siol.net>
9003 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9005 2002-08-10 Borut Razem <borut.razem AT siol.net>
9006 * src/SDCCmain.c (main):
9007 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9008 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9009 The consequence was that some temporary files were not removed.
9012 unification of code in functions tempfilename() and tempfile():
9013 function tempnam() is defined in Visual Studio 6.0 and .NET
9015 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9017 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9018 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9019 - removed compiler command line option /WX: Treats all warnings as errors
9020 - update a list of source files, included into the project
9022 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9023 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9024 changed project type to Generic Project so that can be correcly converted to VS.NET project
9026 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9028 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9030 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9032 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9033 added return 0 statements after assert() to make compiler happy
9035 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9036 added newline in the def file to keep MSC compiler satisfied
9038 * sdcc/src/z80/gen.c:
9039 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9040 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9041 - solved MSC error in function aopDump()
9043 * sdcc_vc.h: define PREFIX as "\\sdcc"
9045 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9046 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9048 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9049 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9050 - Rewrote the register banking algorithm.
9051 - Added pCode live-range analysis to registers (for now, only non-used and
9052 singly-used registers optimized away)
9054 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9056 * 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.
9058 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9059 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9061 2002-04-22 Michael Hope <michaelh AT vroom>

9077 * src/z80/peeph.def: Added transpose redundent load rule.
9079 * src/z80/main.c: Added force callee saves for jaune.
9081 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9083 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9085 2002-03-28 Johan Knol <johan AT balder>
9087 * src/SDCCval.c: fixed bug #532436
9089 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9091 Added "char *Processor" field to the port structure.
