1705 * doc/sdccman.lyx: some reorganization of the PIC16 part, added many
1706 information on the new functions of the c library and more...
1708 2005-03-28 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1710 * src/SDCCBBlock.c (iCodeBreakDown): fixed bug #1170212
1712 2005-03-26 Raphael Neider <rneider AT web.de>
1714 * src/pic16/gen.c (genSkipc): fixed semantics (execute branch
1715 if condition == CARRY)
1716 * (genCmp): adapted to new genSkipc semantics
1717 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
1718 on rIfx (genCmp was broken)
1720 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1722 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
1723 * src/z80/main.c (_keywords[]),
1724 * src/SDCCglobal.h (struct options),
1726 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1727 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1728 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1729 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1730 always available in leading double underscore form. The C99 support is
1731 mostly missing, but it's a start.
1732 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1733 reserved identifier "__data".
1735 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
1737 * src/mcs51/peeph.def: fixed bug 1170013

1779 immedDom() returning wrong block; probably fixes bug #1160833)
1781 2005-03-20 Borut Razem <borut.razem AT siol.net>
1783 * support/scripts/inc2h.pl: WIN32 port

1787 * device/lib/makefile.in: added abs.c and labs.c
1789 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1791 * device/include/stdint.h: added
1792 * device/lib/abs.c: added
1793 * device/lib/labs.c: added
1794 * device/include/stdlib.h: added abs() and labs() prototypes

1809 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1811 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1813 * device/lib/printf_large.c: removed inline assembly for portability and
1814 readability. Use printf_fast if speed or size are more important.
1815 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1816 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1818 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1820 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1821 prevent compiler warning
1823 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1825 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1826 moved to level 0 and declared as static. Also they are explicit
1827 placed in access bank. This was necessery because some times they
1828 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1829 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1830 optimizations. Currently only compare to unsigned char is implemented,
1831 * src/pic16/gen.c: added fReturnIdx array,
1832 * (struct resolvedIfx) is moved to gen.h and made public,
1833 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1834 * (aopForSym): added an optimization to directly store in stack of
1835 the operand of a SEND iCode,
1836 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1837 but as registers instead (AOP_REG) using the fReturnIdx array,
1838 * (pic16_freeAsmop): remove the freed register from the
1839 _G.sregsAlloc field,
1840 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1841 a compare of 'WREG',
1842 * (pic16_popGetTempRegCond): changed function prototype, now
1843 function takes also a bitVector argument v which holds the current
1844 set of registers that are allocated for stack access by aopForSym,
1845 registers allocated in aopForSym for accessing stack symbols are not
1846 any more part of the functions usedRegs field,
1847 * (genCall): some times aopOp is called for a stack variable to be
1848 send, aopForSym might perform the push, if this is true make sure
1849 that genCall doesn't push the variable twice by testing _G.resDirect,
1850 * (genFunction): changed testing for unspecified interrupt number
1851 from 256 to INTNO_UNSPEC,
1852 * modified selection scheme of frame pointer generation. Previously
1853 if function did use local registers a frame pointer was generated,
1854 now a frame pointer is generated only if function has arguments
1855 (that need PLUSW2 register access), or has stack arguments, or the
1856 compiler is not instructed to omit the frame pointer,
1857 * (genEndFunction): before restoring local registers that were saved
1858 in the function preamble, also restore the registers that *might*
1859 have been allocated for stack access,
1860 * (genRet): removed some old comments,
1861 * (genCmp, the active (RN's) version): added a call to the
1862 pic16_genCmp_special function to perform the compare with a more
1863 robust and optimized way,
1864 * (genInline): a feature has been added in inline code generation,
1865 which allows a wildcard variable substitution when writing inline
1866 assembly. Code is incomplete and experimental therefore undocumented,
1867 * (genCast): changed order of aopOp for result and right to allow
1868 aopForSym to directly load the result if possible,
1869 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1870 perform an optimized compare on some selected special occasions,
1871 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1872 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1873 generate an IVT any more,
1874 * src/pic16/main.c (pic16_optionsTable): added command line option
1876 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1877 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1879 * src/pic16/NOTES: Raphael Neider added in list of active developers
1880 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1881 jumptable_end to prevent bug #,
1882 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1883 inCond and outCond fields,
1884 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1885 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1886 turn off register spilling,
1887 * (packRegsForOneUse): synced with other ports' versions although it
1888 is not used currently,
1889 * (pic16_packRegisters): added an optimization while reading
1890 structure bitfields, some registers may be saved (malloc code is
1891 decreased by 80 bytes)
1893 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1895 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1896 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1897 this can be optimized more?
1899 2005-03-10 Raphael Neider <rneider AT web.de>
1901 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1902 genNearPointerGet): (hopefully) fixed access to bitfields via
1903 pointers (p->bitN = x; and x = p->bitN; failed)

2092 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
2093 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2094 this might fix SIGSEGVs on MinGW...
2095 * src/SDCCopt.c (killDeadCode): restored original behaviour
2096 (volatile operands might get thrown away though)
2098 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2538 generated for switch statements. For now you need to set the
2539 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2540 Now 4 algorithms for mcs51 jumptable generation are used:
2541 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2542 addresses loaded pc-relative for up to 112 cases and stack-pushing
2543 target addresses loaded with offset from dptr for up to 256 cases.

5621 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5623 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5624 loaded with the linker search paths (-L arguments) and the libraries
5625 to be linked with the current source (-l arguments). Changes
5626 currently will affect only the pic16 port.
5627 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5628 include path the port specific paths and port specific libraries,
5629 * gplink command now contains the $3 argument,
5630 * src/pic16/device.h,
5631 * src/pic16/device.c,: structure PIC_device is made public and
5632 renamed to PIC16_device, the same for variable Pics which is renamed

5647 Documenting changes from previous commits.
5648 * configure.in (version 1.56),
5649 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5650 when generating output files to configure the pic16 library,
5651 but now I've commented it out, since gputils aren't installed in the
5652 SF compile farm, so library won't compile
5654 * device/lib/Makefile.in (version 1.56): initially I've added in
5655 target 'all' the prerequestive 'model-pic16' so it compiled the
5656 pic16 library, but now I've commented it out for the same reasons
5658 * added targets 'model-pic16' and 'objects-pic16' to compile the
5660 * added target 'port-specific-objects-pic16' to handle the
5661 generated libraries and copy them into the build/ directory
5662 * added target 'clean-intermediate-pic16' to clean intermediate
5663 files into pic16 directory
5664 * in target 'installdirs' added line to create directory pic16 in
5665 the installation path
5667 * device/include/Makefile.in (version 1.11): in target 'install'
5668 added lines to copy all header files to installation path,
5669 * in target 'installdirs' added line create directory for pic16
5670 headers in the installation path
5672 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

5685 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5686 option so that it actually works. Made it specific to the z80, since
5687 the gbz80 doesn't have these kinds of I/O ports.
5689 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5691 * device/include/z180.h,

5757 all over. Telling LaTeX to be less strict with word spacing
5758 to better keep the right margin. Changed some notes about
5759 maintainance of the ports in section 3.2.1 - is it OK like this?
5761 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5801 * src/pic16/peeph.def: all peepholes with movff are commented out,
5802 because there is a problem in the pcode peep optimizer,
5803 * src/pic16/ralloc.c: the register allocator can now reuse local

5896 include information about variables allocated to the overlay
5899 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5901 * as/mcs51/lkmain.c: Help about -Y option

5913 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5915 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5916 (default behaviour).
5918 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5920 A python script to validate compiler diagnostic messages. It can be
5921 used to verify that sdcc complains about bad c source code and
5922 gives a good location of the error.
5923 * support/valdiag/Makefile,
5924 * support/valdiag/valdiag.py,
5925 * support/valdiag/tests/*
5927 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5940 * src/common.h: added ifndef/define/endif macros
5941 around the header file.
5942 Bug reported from Jesus Calvino-Fraga
5944 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5946 * sdcc.spec: updated
5947 * device/include/Makefile.in: don't install CVS directories
5948 * device/lib/Makefile.in: added removal of CVS directories after install
5949 * doc/Makefile: fixed install, added local_icons
5950 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5951 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5952 * src/ds390/gen.c (genRightShift): fixed bug #870788
5953 * src/SDCCast.c (decorateType): fixed bug #870781
5955 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5957 PIC16 port related changes:
5958 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5959 added variable stackPos,
5961 * gen.c: genCall, assignResultValue: added support for
5962 pushing/retrieving function parameters to/from stack,
5963 genFunction,genEndFunction: setup stack frame for the
5965 genAddrOf: will be changed according to bug 863624
5967 * added files genutils.c and genutils.h which contain gen*
5968 debugged and optimised functions extracted from gen.c
5970 * glue.c: added variable 'externs' which holds extern symbols,
5971 pic16emitRegularMap: is modified to properly handle relocatable
5972 symbols under the new scheme,
5973 pic16createInterruptVect: is modified
5974 pic16printPublics: is modified to emit 'global' assembler directives,
5975 added pic16_printExterns to print extern symbols,
5976 pic16glue: initializes stack/frame pointer in the beginning of
5977 the assembly output. Temporary hack, will be corrected later,
5978 because gplink yet does not support stack and SDCC does not
5979 yet support a type of crt0.o object to create the final binary.
5981 * Removed many lines that contain 8051 legacy code.
5982 * The code is finally placed under a 'code' directive.
5983 * Added port specific options.
5985 * _process_pragma: simplified since now we do not need *special*
5986 include file to define SFR registers. But a separate header
5987 will be needed. This will be developed later.
5988 * _pic16_parseOptions: added, parses port specific options:
5989 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5990 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5991 --preplace-udata-with=
5993 * _pic16_setDefaultOptions: modified to initialize section names,
5994 but hack is temporarly out of order since it needs improvement.
5995 * _pic16_genAssemblerPreamble: configuration words are emitted by
5996 their address instead of their name. This part is incomplete and
5997 supports only the 18Fxx2 devices. Other devices will emit an error
5998 during assembly since they do not contain the same set of config
6000 * _pic16_genIVT: is modified,
6002 * pcode.c: added definitions for some hardware registers that are needed
6004 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6005 All PCI entries are updated. Now LFSR is supported.
6006 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6007 * added pic16_newpCodeOpLit2 to support instructions with
6008 two literal arguments
6009 * pic16_pCode2str: corrected code that emits assembler instructions
6010 with two literal operands and those that have an access bit modifier
6011 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6012 this fixes a bug which caused some labels to be lost, when an
6013 assembler directive was added, i.e. banksel,
6014 * pic16_FixRegisterBanking: improved logic that causes the insertion
6016 * InlineFunction: functions that are called once, are not any more
6017 inlined. This can be a port option in the future,
6019 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6021 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6022 hold the corresponding uninitialized symbols,
6023 * pic16_allocProcessorRegister: registers have explicit marked the
6025 * pic16_allocInternalRegister: registers are explicit marked as
6027 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6028 processing list, so bit registers were lost,
6031 * ralloc.h: added field 'accessBank' and original symbol operand
6032 in register definition,
6033 * removed the field isMapped from register definition,
6035 ** Several functions have been removed from various sources:
6036 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6037 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6038 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6039 pic16_assignRelocatableRegisters
6041 ** others have been introduced:
6042 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6043 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6045 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6047 * support/scripts/inc2h.pl: changed definition of BIT_AT
6048 to emit 'sbit at' instead of 'bit at'. This was a request.
6050 PIC16 port related preliminary changes:
6051 * gen.c: prefixed function popRegFromString with
6052 pic16_ and all references to it corrected
6053 * pcode.c: all pic16_pc_* hardware registers prefixed
6054 with underscore (_),
6055 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6056 * ralloc.c: newReg(): when register is REG_SFR then
6057 set address to rIdx,
6058 pic16_allocProcessorRegister(): marks register wasUsed=0
6059 pic16_writeUsedRegs(): added a call to assign processor
6060 registers via pic16_assignFixedRegisters
6062 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6064 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6065 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6066 variables in unused register banks. Also the SSEG is placed
6067 wherever there is enough space for it, and IDATA can be anywhere
6068 in internal RAM. For now compile using -Wl-Y[stack_size].
6069 The mem file is different for this option as well, since it
6070 makes no sense of talking about DSEG lenght.
6072 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6074 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6075 in certain cases, e.g. when ROM assignment, patch provided
6076 from Albert den Haan.
6078 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6248 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6250 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165

7101 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7102 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

7121 A few small changes that speed up the peephole optimizer.
7125 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7127 Try to make the peephole optimizer smarter by maintaining
7128 an association between the assembly source code and the
7129 iCodes that originated them. Put this information to use
7130 with a new peephole rule condition "notVolatile" so that
7131 the rules can be aggressive yet still safe.
7136 * src/mcs51/peeph.def
7138 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7142 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7143 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7144 if the left or right operand symbols have the accuse flag set.
7146 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7148 Changed the type of the result of the ! (NOT) operator to char;
7149 previously it returned the same type as the source. This allows
7150 us to eliminate all the genFloatNot functions (all of its target
7151 implementations were very buggy) since !float can use the same

7163 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7164 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7165 during interrupts. Ensure WSAVE is located at a shared bank address.
7166 2. Fixed page selection in some places
7167 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7168 the registers name strings.
7169 4. Fixed "signed / unsigned compare" compiler warnings.
7170 5. The PIC port manages its own allocation of the general purpose
7171 registers, but makes no attempt to reuse them. As a result when
7172 compiling it soon runs out of general purpose registers. Some
7173 additional code was added to the files pcode.c and device.c to walk
7174 through the function call tree and rename the registers so that they
7184 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7191 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7193 Made bitfield a distinct type from bit so that bitfields
7194 convert as per ANSI C and bits retain their traditional
7195 boolean style behaviour. Implemented bitfield support in
7203 * src/ds390/gen.c: bit v bitfield split
7204 * src/z80/gen.c: New support for bitfields
7205 * support/regression/tests/bitfields.c: reenabled z80,
7208 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7211 access to xdata mapped I/O devices.
7213 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7215 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7217 Cleaned up genPackBits and genUnpackBits and added two helper
7218 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7219 for literal assignments in genPackBits (thanks to Frieder for
7225 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7227 Fixed bug #748310 (pointer to function type mishandled when the
7228 function name is omitted). Also fixed a SIGSEGV when a function
7229 attribute (reentrant, etc) is used on a non-function or on a
7230 function but misplaced before the parameter list.
7232 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7234 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

7257 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7259 Made the constant following the "interrupt" keyword optional. If
7260 omitted, the function will not automatically be given an entry
7261 in the interrupt vector table (similar to #pragma NOIV, but
7262 less syntacticly kludgy). The interrupt number is also now
7263 range checked. Also fixed a bug in the high order bit example

7284 unsigned, but are signed by default
7285 * src/SDCCval.c (constVal): rearranged
7286 * src/SDCCval.c (valMod): preliminary fix
7287 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7781 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
7783 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
7784 it can be defined with CFLAGS when running configure
7785 * src/SDCCmain.c: fixed compiling + linking with object files
7787 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
7789 * configure.in: configure for pic16 port,
7790 added --disable-pic16-port
7791 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7792 * src/SDCCmain.c: linkOptions is changed to set *,
7793 added if/endif conditional macros to remove options help
7794 messages from optionsTable when a port is not configured, added
7795 support for the PIc16 port in the ports table, when executing
7796 the compiler with no port specified on command line, a default
7797 port is selected with the new macro DEFAULT_PORT which is
7798 defined in port.h, in setDefaultOptions() linkOptions is removed
7799 from initialization assignment, since now it is a set,
7800 parseCmdLine uses setParseWithComma for linkOptions, in
7801 linkEdit() linkOptions are accessed with new function indexSet()
7802 which returns the i'th item of a set variable. See SDCCset.c, in
7803 linkEdit() when calling buildCmdLine(), added linkOptions as
7804 last argument. Now users can pass arguments to gplink via the
7805 -Wl option, main() uses pic16glue() to glue up pic16 programs
7806 * src/SDCCpeeph.c: various changes to support pic16

7817 * src/pic16/glue.c: commented out some error producing lines
7818 * src/pic16/main.c: __config directives are commented out to stop
7819 gpasm complaining and test the linkage with gplink, _linkCmd and
7820 _asmCmd changed to be more gplink and gpasm friendly
7821 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7822 produced an error when parsed, peep rule 12 is added to utilize
7823 movff, but it is commented out since the pCode does not support
7824 yet a command with 2 address arguments
7826 2003-05-18 <johan AT balder>
7828 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7855 2003-05-11 Borut Razem <borut.razem AT siol.net>
7857 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7858 the path of bin directory, so that PATH is the only env. variable, which has to be set
7859 in case of standard installation.

8863 * src/SDCCicode.c: fixed array add
8865 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8866 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8867 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8869 2003-01-04 <johan AT balder>
8871 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8873 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8874 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8876 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

8886 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8887 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8889 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8891 * in \sdcc\as\mcs51\ changed these files in order to create an
8892 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8893 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8894 following files to include the previous two files: aslink.dsp,
8895 Makefile.aslink, Makefile.bcc, and Makefile.in.
8897 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8898 .adb instead of .cdb
8900 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8902 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8903 value from option --iram-size.
8905 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8907 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8910 2002-09-18 <wiml AT hhhh.org>
8912 * SDCClrange.h: exposed setFromRange() and setToRange()
8913 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8914 packRegsForAccUse() (bug 542397)
8915 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8916 multiple times and emitting the fetch operations more than once
8917 added aopGetUsesAcc() function to allow binary operators to
8918 fetch their operands in the correct order; made genMinus() emit
8919 compact code for X = LITERAL - Y
8921 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8922 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8923 sprintf() in line 1267.
8925 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8926 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8929 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8930 Changes to aslink (All the changes are marked with 'JCF'):
8932 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8935 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8936 area BSEG. Also moves, if possible, the DATA area down into the internal
8937 ram so more space is available.
8939 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8942 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8943 not bytes. Function summary() which creates a memory usage summary
8944 file with extension .mem. Reports of overlaping stack and small stack
8945 size. If the space for the stack is less than 16 bytes aslink trows a
8948 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8949 the 8051. Option 'y' for memory summary output file.
8951 Changes to sdcc (All the changes are marked with 'JCF'):
8953 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8955 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8956 overlaying area for it (uses RegBankUsed[4]).
8958 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8959 bank zero as used by default. By default aslink locates the stack
8960 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8961 the creation of the .mem file. Delegates the allocation of data area
8962 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8963 the begining of the stack area to aslink.
8965 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8966 glue() in SDCCglue.c creates an area for it.
8968 2002-09-03 Borut Razem <borut.razem AT siol.net>
8969 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8970 sdcc/src/pic/glue.c:
8971 introduced atexit() handler for teporay files removal in case of
8972 errors, assertions, ...
8974 2002-08-29 Borut Razem <borut.razem AT siol.net>
8975 * sdcc/support/cpp2/auto-host_vc_in.h:
8976 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8977 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8978 Maybe there is a similar problem with BORLANDC? It should be checked!
8980 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8981 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8982 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8983 was not executed, and the compiler (cl) launched a warning:
8984 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8986 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8987 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8989 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8990 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8992 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8993 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8994 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8995 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8996 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8997 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8998 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8999 - added Release configuration in VS projects
9000 - review of compiler an linker options
9001 - VC .exe files are generated in bin_vc directory, not to interfere
9002 with binaries generated from other projects (cygwin, mingw, bcc ...)
9004 * sdcc/src/yacc.dsp: added
9006 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9007 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9008 and insert the version number definitions from .version
9010 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9012 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9013 added - genarate auto-host.h using auto-host_vc_in.h as template
9016 removed from CVS, generated automatically
9018 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9019 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9021 2002-08-11 Borut Razem <borut.razem AT siol.net>
9022 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9024 2002-08-10 Borut Razem <borut.razem AT siol.net>
9025 * src/SDCCmain.c (main):
9026 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9027 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9028 The consequence was that some temporary files were not removed.
9031 unification of code in functions tempfilename() and tempfile():
9032 function tempnam() is defined in Visual Studio 6.0 and .NET
9034 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9036 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9037 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9038 - removed compiler command line option /WX: Treats all warnings as errors
9039 - update a list of source files, included into the project
9041 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9042 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9043 changed project type to Generic Project so that can be correcly converted to VS.NET project
9045 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9047 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9049 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9051 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9052 added return 0 statements after assert() to make compiler happy
9054 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9055 added newline in the def file to keep MSC compiler satisfied
9057 * sdcc/src/z80/gen.c:
9058 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9059 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9060 - solved MSC error in function aopDump()
9062 * sdcc_vc.h: define PREFIX as "\\sdcc"
9064 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9065 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9067 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9068 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9069 - Rewrote the register banking algorithm.
9070 - Added pCode live-range analysis to registers (for now, only non-used and
9071 singly-used registers optimized away)
9073 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
