1712 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
1715 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1717 * src/port.h (struct PORT),

1743 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
1744 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
1745 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
1746 immedDom() returning wrong block; probably fixes bug #1160833)
1748 2005-03-20 Borut Razem <borut.razem AT siol.net>
1750 * support/scripts/inc2h.pl: WIN32 port
1752 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1754 * device/lib/makefile.in: added abs.c and labs.c
1756 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1758 * device/include/stdint.h: added
1759 * device/lib/abs.c: added
1760 * device/lib/labs.c: added
1761 * device/include/stdlib.h: added abs() and labs() prototypes
1762 * device/lib/libsdcc.lib: added abs and labs
1763 * device/include/float.h,

1768 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1770 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
1773 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1775 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
1776 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1778 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1780 * device/lib/printf_large.c: removed inline assembly for portability and
1781 readability. Use printf_fast if speed or size are more important.
1782 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1783 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1785 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1787 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1788 prevent compiler warning
1790 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1792 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1793 moved to level 0 and declared as static. Also they are explicit
1794 placed in access bank. This was necessery because some times they
1795 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1796 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1797 optimizations. Currently only compare to unsigned char is implemented,
1798 * src/pic16/gen.c: added fReturnIdx array,
1799 * (struct resolvedIfx) is moved to gen.h and made public,
1800 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1801 * (aopForSym): added an optimization to directly store in stack of
1802 the operand of a SEND iCode,
1803 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1804 but as registers instead (AOP_REG) using the fReturnIdx array,
1805 * (pic16_freeAsmop): remove the freed register from the
1806 _G.sregsAlloc field,
1807 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1808 a compare of 'WREG',
1809 * (pic16_popGetTempRegCond): changed function prototype, now
1810 function takes also a bitVector argument v which holds the current
1811 set of registers that are allocated for stack access by aopForSym,
1812 registers allocated in aopForSym for accessing stack symbols are not
1813 any more part of the functions usedRegs field,
1814 * (genCall): some times aopOp is called for a stack variable to be
1815 send, aopForSym might perform the push, if this is true make sure
1816 that genCall doesn't push the variable twice by testing _G.resDirect,
1817 * (genFunction): changed testing for unspecified interrupt number
1818 from 256 to INTNO_UNSPEC,
1819 * modified selection scheme of frame pointer generation. Previously
1820 if function did use local registers a frame pointer was generated,
1821 now a frame pointer is generated only if function has arguments
1822 (that need PLUSW2 register access), or has stack arguments, or the
1823 compiler is not instructed to omit the frame pointer,
1824 * (genEndFunction): before restoring local registers that were saved
1825 in the function preamble, also restore the registers that *might*
1826 have been allocated for stack access,
1827 * (genRet): removed some old comments,
1828 * (genCmp, the active (RN's) version): added a call to the
1829 pic16_genCmp_special function to perform the compare with a more
1830 robust and optimized way,
1831 * (genInline): a feature has been added in inline code generation,
1832 which allows a wildcard variable substitution when writing inline
1833 assembly. Code is incomplete and experimental therefore undocumented,
1834 * (genCast): changed order of aopOp for result and right to allow
1835 aopForSym to directly load the result if possible,
1836 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1837 perform an optimized compare on some selected special occasions,
1838 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1839 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1840 generate an IVT any more,
1841 * src/pic16/main.c (pic16_optionsTable): added command line option
1843 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1844 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1846 * src/pic16/NOTES: Raphael Neider added in list of active developers
1847 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1848 jumptable_end to prevent bug #,
1849 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1850 inCond and outCond fields,
1851 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1852 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1853 turn off register spilling,
1854 * (packRegsForOneUse): synced with other ports' versions although it
1855 is not used currently,
1856 * (pic16_packRegisters): added an optimization while reading
1857 structure bitfields, some registers may be saved (malloc code is
1858 decreased by 80 bytes)
1860 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1862 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1863 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1864 this can be optimized more?
1866 2005-03-10 Raphael Neider <rneider AT web.de>
1868 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1869 genNearPointerGet): (hopefully) fixed access to bitfields via
1870 pointers (p->bitN = x; and x = p->bitN; failed)
1872 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
1874 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

2505 generated for switch statements. For now you need to set the
2506 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2507 Now 4 algorithms for mcs51 jumptable generation are used:
2508 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

2540 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2542 * added libc directory. The current version of LibC contains string
2543 functions, ctype functions and macros and some functions of the
2544 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2545 be extensively tested in the future. Standard disclaimer here.
2546 Library is not automatically build yet. But one can build it by

2558 * (pic16_storeForReturn): optimized return of 0,
2559 * (genCmp): experimental code for new genCmp which uses PIC18's
2560 special compare&skip instructions. Initial tests fail some times
2561 with variables grater than 1 byte in size, so new code is disabled,
2562 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2564 * (genCast): began a fix to optimize the casting of a bit to another
2565 bit, now assigning a bitfield to another bitfield will fail, sorry,

2573 * (isBankInstruction): modified to return 0 for no banking instruction,
2574 and 1 for banking instruction,
2575 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2576 caused stop processing pCodes after a inline assembly block,
2577 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2579 registers when it shouldn't,
2580 * src/pic16/ralloc.c (allocReg): add preliminary support for
2581 supporting a limited set of temporary registers,

5588 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5590 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5591 loaded with the linker search paths (-L arguments) and the libraries
5592 to be linked with the current source (-l arguments). Changes
5593 currently will affect only the pic16 port.
5594 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5595 include path the port specific paths and port specific libraries,
5596 * gplink command now contains the $3 argument,
5597 * src/pic16/device.h,
5598 * src/pic16/device.c,: structure PIC_device is made public and
5599 renamed to PIC16_device, the same for variable Pics which is renamed

5614 Documenting changes from previous commits.
5615 * configure.in (version 1.56),
5616 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5617 when generating output files to configure the pic16 library,
5618 but now I've commented it out, since gputils aren't installed in the
5619 SF compile farm, so library won't compile
5621 * device/lib/Makefile.in (version 1.56): initially I've added in
5622 target 'all' the prerequestive 'model-pic16' so it compiled the
5623 pic16 library, but now I've commented it out for the same reasons
5625 * added targets 'model-pic16' and 'objects-pic16' to compile the
5627 * added target 'port-specific-objects-pic16' to handle the
5628 generated libraries and copy them into the build/ directory
5629 * added target 'clean-intermediate-pic16' to clean intermediate
5630 files into pic16 directory
5631 * in target 'installdirs' added line to create directory pic16 in
5632 the installation path
5634 * device/include/Makefile.in (version 1.11): in target 'install'
5635 added lines to copy all header files to installation path,
5636 * in target 'installdirs' added line create directory for pic16
5637 headers in the installation path

5652 * src/z80/main.c (_parseOptions): fixed the portmode= command line
5653 option so that it actually works. Made it specific to the z80, since
5654 the gbz80 doesn't have these kinds of I/O ports.
5656 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5658 * device/include/z180.h,

5682 via literal number. The symbol is placed in the corresponding
5683 position of the data ram
5684 * (pic16_dump_section): relocatable and absolute uninitialized
5685 data are now emitted in sorted order to reduce section naming,
5686 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5687 weren't marked as being in the access bank,
5689 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5691 Added portion of GNU PIC Library under the directory
5692 device/include/pic16 and device/lib/pic16. These files
5693 contain the declarations of SFRs for the PIC18Fxx2 devices.
5694 The directory is initialized via configure from toplevel.

5724 all over. Telling LaTeX to be less strict with word spacing
5725 to better keep the right margin. Changed some notes about
5726 maintainance of the ports in section 3.2.1 - is it OK like this?
5728 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5768 * src/pic16/peeph.def: all peepholes with movff are commented out,
5769 because there is a problem in the pcode peep optimizer,
5770 * src/pic16/ralloc.c: the register allocator can now reuse local

5880 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5882 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5883 (default behaviour).
5885 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5887 A python script to validate compiler diagnostic messages. It can be
5888 used to verify that sdcc complains about bad c source code and
5889 gives a good location of the error.
5890 * support/valdiag/Makefile,
5891 * support/valdiag/valdiag.py,
5892 * support/valdiag/tests/*
5894 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5908 around the header file.
5909 Bug reported from Jesus Calvino-Fraga
5911 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5913 * sdcc.spec: updated
5914 * device/include/Makefile.in: don't install CVS directories
5915 * device/lib/Makefile.in: added removal of CVS directories after install
5916 * doc/Makefile: fixed install, added local_icons
5917 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5918 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5919 * src/ds390/gen.c (genRightShift): fixed bug #870788
5920 * src/SDCCast.c (decorateType): fixed bug #870781
5922 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5924 PIC16 port related changes:
5925 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5926 added variable stackPos,
5928 * gen.c: genCall, assignResultValue: added support for
5929 pushing/retrieving function parameters to/from stack,
5930 genFunction,genEndFunction: setup stack frame for the
5932 genAddrOf: will be changed according to bug 863624
5934 * added files genutils.c and genutils.h which contain gen*
5935 debugged and optimised functions extracted from gen.c
5937 * glue.c: added variable 'externs' which holds extern symbols,
5938 pic16emitRegularMap: is modified to properly handle relocatable
5939 symbols under the new scheme,
5940 pic16createInterruptVect: is modified
5941 pic16printPublics: is modified to emit 'global' assembler directives,
5942 added pic16_printExterns to print extern symbols,
5943 pic16glue: initializes stack/frame pointer in the beginning of
5944 the assembly output. Temporary hack, will be corrected later,
5945 because gplink yet does not support stack and SDCC does not
5946 yet support a type of crt0.o object to create the final binary.
5948 * Removed many lines that contain 8051 legacy code.
5949 * The code is finally placed under a 'code' directive.
5950 * Added port specific options.
5952 * _process_pragma: simplified since now we do not need *special*
5953 include file to define SFR registers. But a separate header
5954 will be needed. This will be developed later.
5955 * _pic16_parseOptions: added, parses port specific options:
5956 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5957 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5958 --preplace-udata-with=
5960 * _pic16_setDefaultOptions: modified to initialize section names,
5961 but hack is temporarly out of order since it needs improvement.
5962 * _pic16_genAssemblerPreamble: configuration words are emitted by
5963 their address instead of their name. This part is incomplete and
5964 supports only the 18Fxx2 devices. Other devices will emit an error
5965 during assembly since they do not contain the same set of config
5967 * _pic16_genIVT: is modified,
5969 * pcode.c: added definitions for some hardware registers that are needed
5971 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5972 All PCI entries are updated. Now LFSR is supported.
5973 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5974 * added pic16_newpCodeOpLit2 to support instructions with
5975 two literal arguments
5976 * pic16_pCode2str: corrected code that emits assembler instructions
5977 with two literal operands and those that have an access bit modifier
5978 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5979 this fixes a bug which caused some labels to be lost, when an
5980 assembler directive was added, i.e. banksel,
5981 * pic16_FixRegisterBanking: improved logic that causes the insertion
5983 * InlineFunction: functions that are called once, are not any more
5984 inlined. This can be a port option in the future,
5986 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5988 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5989 hold the corresponding uninitialized symbols,
5990 * pic16_allocProcessorRegister: registers have explicit marked the
5992 * pic16_allocInternalRegister: registers are explicit marked as
5994 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5995 processing list, so bit registers were lost,
5998 * ralloc.h: added field 'accessBank' and original symbol operand
5999 in register definition,
6000 * removed the field isMapped from register definition,
6002 ** Several functions have been removed from various sources:
6003 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6004 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6005 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6006 pic16_assignRelocatableRegisters
6008 ** others have been introduced:
6009 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6010 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6012 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6014 * support/scripts/inc2h.pl: changed definition of BIT_AT
6015 to emit 'sbit at' instead of 'bit at'. This was a request.
6017 PIC16 port related preliminary changes:
6018 * gen.c: prefixed function popRegFromString with
6019 pic16_ and all references to it corrected
6020 * pcode.c: all pic16_pc_* hardware registers prefixed
6021 with underscore (_),
6022 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6023 * ralloc.c: newReg(): when register is REG_SFR then
6024 set address to rIdx,
6025 pic16_allocProcessorRegister(): marks register wasUsed=0
6026 pic16_writeUsedRegs(): added a call to assign processor
6027 registers via pic16_assignFixedRegisters
6029 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6031 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6032 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6033 variables in unused register banks. Also the SSEG is placed
6034 wherever there is enough space for it, and IDATA can be anywhere
6035 in internal RAM. For now compile using -Wl-Y[stack_size].
6036 The mem file is different for this option as well, since it
6037 makes no sense of talking about DSEG lenght.
6039 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6041 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6042 in certain cases, e.g. when ROM assignment, patch provided
6043 from Albert den Haan.
6045 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6187 SDCC_NOGENRAMCLEAR to disable this.
6188 * src/mcs51/peephole.def,
6189 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
6190 (allows non-interrupt and interrupt code to safely compete for a resource
6191 without the non-interrupt code having to disable interrupts)
6193 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6195 * src/SDCCicode.c (geniCodeAdd),

6215 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6217 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165

7068 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7069 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7070 type for bits was changed. It resulted in bit variables becoming
7071 global, which is not permitted in PIC 14 assembly output.

7088 A few small changes that speed up the peephole optimizer.
7092 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7094 Try to make the peephole optimizer smarter by maintaining
7095 an association between the assembly source code and the
7096 iCodes that originated them. Put this information to use
7097 with a new peephole rule condition "notVolatile" so that
7098 the rules can be aggressive yet still safe.
7103 * src/mcs51/peeph.def
7105 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7109 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7110 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7111 if the left or right operand symbols have the accuse flag set.
7113 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7115 Changed the type of the result of the ! (NOT) operator to char;
7116 previously it returned the same type as the source. This allows
7117 us to eliminate all the genFloatNot functions (all of its target
7118 implementations were very buggy) since !float can use the same
7121 * src/SDCCicode.c (ast2iCode): ! returns char

7130 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7131 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7132 during interrupts. Ensure WSAVE is located at a shared bank address.
7133 2. Fixed page selection in some places
7134 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7135 the registers name strings.
7136 4. Fixed "signed / unsigned compare" compiler warnings.
7137 5. The PIC port manages its own allocation of the general purpose
7138 registers, but makes no attempt to reuse them. As a result when
7139 compiling it soon runs out of general purpose registers. Some
7140 additional code was added to the files pcode.c and device.c to walk
7141 through the function call tree and rename the registers so that they
7151 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7152 genPlus() & genMinus() when the result is the same as left or right

7158 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7160 Made bitfield a distinct type from bit so that bitfields
7161 convert as per ANSI C and bits retain their traditional
7162 boolean style behaviour. Implemented bitfield support in
7170 * src/ds390/gen.c: bit v bitfield split
7171 * src/z80/gen.c: New support for bitfields
7172 * support/regression/tests/bitfields.c: reenabled z80,
7175 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7177 Rules 246.x, 247.x relate to bitfields, the others speed up
7178 access to xdata mapped I/O devices.
7180 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7182 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7184 Cleaned up genPackBits and genUnpackBits and added two helper
7185 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7186 for literal assignments in genPackBits (thanks to Frieder for
7192 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7194 Fixed bug #748310 (pointer to function type mishandled when the
7195 function name is omitted). Also fixed a SIGSEGV when a function
7196 attribute (reentrant, etc) is used on a non-function or on a
7197 function but misplaced before the parameter list.
7199 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7201 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7202 * support/Util/SDCCerr.h,

7226 Made the constant following the "interrupt" keyword optional. If
7227 omitted, the function will not automatically be given an entry
7228 in the interrupt vector table (similar to #pragma NOIV, but
7229 less syntacticly kludgy). The interrupt number is also now
7230 range checked. Also fixed a bug in the high order bit example
7237 * support/Util/SDCCerr.c

7761 messages from optionsTable when a port is not configured, added
7762 support for the PIc16 port in the ports table, when executing
7763 the compiler with no port specified on command line, a default
7764 port is selected with the new macro DEFAULT_PORT which is
7765 defined in port.h, in setDefaultOptions() linkOptions is removed
7766 from initialization assignment, since now it is a set,
7767 parseCmdLine uses setParseWithComma for linkOptions, in
7768 linkEdit() linkOptions are accessed with new function indexSet()
7769 which returns the i'th item of a set variable. See SDCCset.c, in

8830 * src/SDCCicode.c: fixed array add
8832 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8833 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8834 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8836 2003-01-04 <johan AT balder>
8838 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8840 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8841 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8843 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

8853 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8854 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8856 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8858 * in \sdcc\as\mcs51\ changed these files in order to create an
8859 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8860 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8861 following files to include the previous two files: aslink.dsp,
8862 Makefile.aslink, Makefile.bcc, and Makefile.in.
8864 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8865 .adb instead of .cdb
8867 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8869 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8870 value from option --iram-size.
8872 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8874 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8877 2002-09-18 <wiml AT hhhh.org>
8879 * SDCClrange.h: exposed setFromRange() and setToRange()
8880 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8881 packRegsForAccUse() (bug 542397)
8882 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8883 multiple times and emitting the fetch operations more than once
8884 added aopGetUsesAcc() function to allow binary operators to
8885 fetch their operands in the correct order; made genMinus() emit
8886 compact code for X = LITERAL - Y
8888 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8889 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8890 sprintf() in line 1267.
8892 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8893 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8896 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8897 Changes to aslink (All the changes are marked with 'JCF'):
8899 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8902 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8903 area BSEG. Also moves, if possible, the DATA area down into the internal
8904 ram so more space is available.
8906 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8909 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8910 not bytes. Function summary() which creates a memory usage summary
8911 file with extension .mem. Reports of overlaping stack and small stack
8912 size. If the space for the stack is less than 16 bytes aslink trows a
8915 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8916 the 8051. Option 'y' for memory summary output file.
8918 Changes to sdcc (All the changes are marked with 'JCF'):
8920 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8922 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8923 overlaying area for it (uses RegBankUsed[4]).
8925 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8926 bank zero as used by default. By default aslink locates the stack
8927 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8928 the creation of the .mem file. Delegates the allocation of data area
8929 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8930 the begining of the stack area to aslink.
8932 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8933 glue() in SDCCglue.c creates an area for it.
8935 2002-09-03 Borut Razem <borut.razem AT siol.net>
8936 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8937 sdcc/src/pic/glue.c:
8938 introduced atexit() handler for teporay files removal in case of
8939 errors, assertions, ...
8941 2002-08-29 Borut Razem <borut.razem AT siol.net>
8942 * sdcc/support/cpp2/auto-host_vc_in.h:
8943 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8944 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8945 Maybe there is a similar problem with BORLANDC? It should be checked!
8947 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8948 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8949 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8950 was not executed, and the compiler (cl) launched a warning:
8951 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8953 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8954 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8956 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8957 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8959 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8960 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8961 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8962 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8963 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8964 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8965 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8966 - added Release configuration in VS projects
8967 - review of compiler an linker options
8968 - VC .exe files are generated in bin_vc directory, not to interfere
8969 with binaries generated from other projects (cygwin, mingw, bcc ...)
8971 * sdcc/src/yacc.dsp: added
8973 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8974 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8975 and insert the version number definitions from .version
8977 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8979 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8980 added - genarate auto-host.h using auto-host_vc_in.h as template
8983 removed from CVS, generated automatically
8985 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8986 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8988 2002-08-11 Borut Razem <borut.razem AT siol.net>
8989 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8991 2002-08-10 Borut Razem <borut.razem AT siol.net>
8992 * src/SDCCmain.c (main):
8993 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8994 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8995 The consequence was that some temporary files were not removed.
8998 unification of code in functions tempfilename() and tempfile():
8999 function tempnam() is defined in Visual Studio 6.0 and .NET
9001 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9003 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9004 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9005 - removed compiler command line option /WX: Treats all warnings as errors
9006 - update a list of source files, included into the project
9008 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9009 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9010 changed project type to Generic Project so that can be correcly converted to VS.NET project
9012 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9014 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9016 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9018 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9019 added return 0 statements after assert() to make compiler happy
9021 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9022 added newline in the def file to keep MSC compiler satisfied
9024 * sdcc/src/z80/gen.c:
9025 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9026 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9027 - solved MSC error in function aopDump()
9029 * sdcc_vc.h: define PREFIX as "\\sdcc"
9031 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9032 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9035 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9036 - Rewrote the register banking algorithm.
9037 - Added pCode live-range analysis to registers (for now, only non-used and
9038 singly-used registers optimized away)
9040 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9042 * 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.
9044 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9045 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9047 2002-04-22 Michael Hope <michaelh AT vroom>

9067 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9069 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9071 2002-03-28 Johan Knol <johan AT balder>
9073 * src/SDCCval.c: fixed bug #532436
9075 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9077 Added "char *Processor" field to the port structure.
9080 Added -p option. Allows port dependent processor to be specified.
9083 Initialized the new field char *Processor field to NULL in all ports
9086 Compiler generated registers for interrupt context saving
9087 were not getting allocated.
9089 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9092 Fixed left shift. Will promote the left side of a left shift
9093 if a) left shifting more than size of operand or b) when assigned
