2297 * ChangeLog: changed "@" to " AT " in hopes of reducing spam and
2298 virus/worm forged address usage.
2300 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
2302 Fixed promotion, it should be done on AST level:

2318 * support/regression/generate-cases.py (main): Changed from inline
2321 * doc/Makefile (install): Changed to depth first to get rid of
2322 missing directory install warning.
2324 * as/Makefile (install-doc): Made work on Mac.
2326 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
2328 * src/SDCCast.c: added an additional type flow in decorateType() of
2329 opposite direction, see feature request #860006; it's enabled at runtime
2330 by setting the environment variable SDCC_NEWTYPEFLOW
2331 * src/SDCCast.h: changed prototype of decorateType()
2332 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
2333 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
2334 'char' to 'int' can be omitted, if both operands are 'unsigned char';
2335 see feature request #877103
2336 * src/SDCCval.c: updated call of decorateType()
2337 (valBitwise): fixed bug #882876
2338 (valMinus): added promotion
2339 (valLogicAndOr): result is unsigned

2364 * src/pic/ralloc.h: applied patch from Slade Rich;
2365 added support for multiple code pages and multiple RAM banks on the
2366 PIC 14 port. The ASM files now no longer simply assume all the
2367 code / RAM are in the same page / bank. This means the linker can
2368 safely allocate code/RAM of separate ASM files to different pages/banks.
2369 * doc/sdccman.lyx: added Slade's tips
2370 * src/mcs51/peeph.def: fixed bug #880768

2412 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
2414 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
2415 loaded with the linker search paths (-L arguments) and the libraries
2416 to be linked with the current source (-l arguments). Changes
2417 currently will affect only the pic16 port.
2418 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
2419 include path the port specific paths and port specific libraries,
2420 * gplink command now contains the $3 argument,
2421 * src/pic16/device.h,
2422 * src/pic16/device.c,: structure PIC_device is made public and
2423 renamed to PIC16_device, the same for variable Pics which is renamed

2438 Documenting changes from previous commits.
2439 * configure.in (version 1.56),
2440 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
2441 when generating output files to configure the pic16 library,
2442 but now I've commented it out, since gputils aren't installed in the
2443 SF compile farm, so library won't compile
2445 * device/lib/Makefile.in (version 1.56): initially I've added in
2446 target 'all' the prerequestive 'model-pic16' so it compiled the
2447 pic16 library, but now I've commented it out for the same reasons
2449 * added targets 'model-pic16' and 'objects-pic16' to compile the
2451 * added target 'port-specific-objects-pic16' to handle the
2452 generated libraries and copy them into the build/ directory
2453 * added target 'clean-intermediate-pic16' to clean intermediate
2454 files into pic16 directory
2455 * in target 'installdirs' added line to create directory pic16 in
2456 the installation path
2458 * device/include/Makefile.in (version 1.11): in target 'install'
2459 added lines to copy all header files to installation path,
2460 * in target 'installdirs' added line create directory for pic16
2461 headers in the installation path

2476 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2477 option so that it actually works. Made it specific to the z80, since
2478 the gbz80 doesn't have these kinds of I/O ports.
2480 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2482 * device/include/z180.h,

2504 Mainly changes to support compilation of the device libraries
2505 * src/pic16/device.c: stack is allocated via symbol and not
2506 via literal number. The symbol is placed in the corresponding
2507 position of the data ram
2508 * (pic16_dump_section): relocatable and absolute uninitialized
2509 data are now emitted in sorted order to reduce section naming,
2510 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2511 weren't marked as being in the access bank,
2513 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2515 Added portion of GNU PIC Library under the directory
2516 device/include/pic16 and device/lib/pic16. These files
2517 contain the declarations of SFRs for the PIC18Fxx2 devices.
2518 The directory is initialized via configure from toplevel.

2548 all over. Telling LaTeX to be less strict with word spacing
2549 to better keep the right margin. Changed some notes about
2550 maintainance of the ports in section 3.2.1 - is it OK like this?
2552 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2733 Bug reported from Jesus Calvino-Fraga
2735 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2737 * sdcc.spec: updated
2738 * device/include/Makefile.in: don't install CVS directories

2746 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2748 PIC16 port related changes:
2749 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2750 added variable stackPos,
2752 * gen.c: genCall, assignResultValue: added support for
2753 pushing/retrieving function parameters to/from stack,
2754 genFunction,genEndFunction: setup stack frame for the
2756 genAddrOf: will be changed according to bug 863624
2758 * added files genutils.c and genutils.h which contain gen*
2759 debugged and optimised functions extracted from gen.c
2761 * glue.c: added variable 'externs' which holds extern symbols,
2762 pic16emitRegularMap: is modified to properly handle relocatable
2763 symbols under the new scheme,
2764 pic16createInterruptVect: is modified
2765 pic16printPublics: is modified to emit 'global' assembler directives,
2766 added pic16_printExterns to print extern symbols,
2767 pic16glue: initializes stack/frame pointer in the beginning of
2768 the assembly output. Temporary hack, will be corrected later,
2769 because gplink yet does not support stack and SDCC does not
2770 yet support a type of crt0.o object to create the final binary.
2772 * Removed many lines that contain 8051 legacy code.
2773 * The code is finally placed under a 'code' directive.
2774 * Added port specific options.
2776 * _process_pragma: simplified since now we do not need *special*
2777 include file to define SFR registers. But a separate header
2778 will be needed. This will be developed later.
2779 * _pic16_parseOptions: added, parses port specific options:
2780 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2781 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2782 --preplace-udata-with=
2784 * _pic16_setDefaultOptions: modified to initialize section names,
2785 but hack is temporarly out of order since it needs improvement.
2786 * _pic16_genAssemblerPreamble: configuration words are emitted by
2787 their address instead of their name. This part is incomplete and
2788 supports only the 18Fxx2 devices. Other devices will emit an error
2789 during assembly since they do not contain the same set of config
2791 * _pic16_genIVT: is modified,
2793 * pcode.c: added definitions for some hardware registers that are needed
2795 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2796 All PCI entries are updated. Now LFSR is supported.
2797 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2798 * added pic16_newpCodeOpLit2 to support instructions with
2799 two literal arguments
2800 * pic16_pCode2str: corrected code that emits assembler instructions
2801 with two literal operands and those that have an access bit modifier
2802 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2803 this fixes a bug which caused some labels to be lost, when an
2804 assembler directive was added, i.e. banksel,
2805 * pic16_FixRegisterBanking: improved logic that causes the insertion
2807 * InlineFunction: functions that are called once, are not any more
2808 inlined. This can be a port option in the future,
2810 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2812 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2813 hold the corresponding uninitialized symbols,
2814 * pic16_allocProcessorRegister: registers have explicit marked the
2816 * pic16_allocInternalRegister: registers are explicit marked as
2818 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2819 processing list, so bit registers were lost,
2822 * ralloc.h: added field 'accessBank' and original symbol operand
2823 in register definition,
2824 * removed the field isMapped from register definition,
2826 ** Several functions have been removed from various sources:
2827 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2828 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2829 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2830 pic16_assignRelocatableRegisters
2832 ** others have been introduced:
2833 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2834 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2836 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2838 * support/scripts/inc2h.pl: changed definition of BIT_AT
2839 to emit 'sbit at' instead of 'bit at'. This was a request.
2841 PIC16 port related preliminary changes:
2842 * gen.c: prefixed function popRegFromString with
2843 pic16_ and all references to it corrected
2844 * pcode.c: all pic16_pc_* hardware registers prefixed
2845 with underscore (_),
2846 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2847 * ralloc.c: newReg(): when register is REG_SFR then
2848 set address to rIdx,
2849 pic16_allocProcessorRegister(): marks register wasUsed=0
2850 pic16_writeUsedRegs(): added a call to assign processor
2851 registers via pic16_assignFixedRegisters
2853 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2855 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2856 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2857 variables in unused register banks. Also the SSEG is placed
2858 wherever there is enough space for it, and IDATA can be anywhere
2859 in internal RAM. For now compile using -Wl-Y[stack_size].
2860 The mem file is different for this option as well, since it
2861 makes no sense of talking about DSEG lenght.
2863 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2865 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2866 in certain cases, e.g. when ROM assignment, patch provided
2867 from Albert den Haan.

3110 * src/SDCCast.c (decorateType): disabled a transformation I added in
3111 revision 1.188 (access to fields of a structure at an absolute address);
3112 it breaks with bitfields, extern declarations, and gcse analysis.
3113 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
3114 could be assigned through a pointer, so don't complain.

3222 xdata initialization slightly shorter
3224 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3871 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3872 fetching of the pointer
3873 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3874 copied from genNearPointerSet()
3875 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3876 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

3892 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3893 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3894 type for bits was changed. It resulted in bit variables becoming
3895 global, which is not permitted in PIC 14 assembly output.
3897 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3899 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3912 A few small changes that speed up the peephole optimizer.
3916 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3918 Try to make the peephole optimizer smarter by maintaining
3919 an association between the assembly source code and the
3920 iCodes that originated them. Put this information to use
3921 with a new peephole rule condition "notVolatile" so that
3922 the rules can be aggressive yet still safe.
3927 * src/mcs51/peeph.def
3929 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3933 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3934 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3935 if the left or right operand symbols have the accuse flag set.
3937 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3939 Changed the type of the result of the ! (NOT) operator to char;
3940 previously it returned the same type as the source. This allows
3941 us to eliminate all the genFloatNot functions (all of its target
3942 implementations were very buggy) since !float can use the same
3945 * src/SDCCicode.c (ast2iCode): ! returns char

3954 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3955 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3956 during interrupts. Ensure WSAVE is located at a shared bank address.
3957 2. Fixed page selection in some places
3958 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3959 the registers name strings.
3960 4. Fixed "signed / unsigned compare" compiler warnings.
3961 5. The PIC port manages its own allocation of the general purpose
3962 registers, but makes no attempt to reuse them. As a result when
3963 compiling it soon runs out of general purpose registers. Some
3964 additional code was added to the files pcode.c and device.c to walk
3965 through the function call tree and rename the registers so that they
3975 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

3982 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3984 Made bitfield a distinct type from bit so that bitfields
3985 convert as per ANSI C and bits retain their traditional
3986 boolean style behaviour. Implemented bitfield support in
3994 * src/ds390/gen.c: bit v bitfield split
3995 * src/z80/gen.c: New support for bitfields
3996 * support/regression/tests/bitfields.c: reenabled z80,
3999 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4001 Rules 246.x, 247.x relate to bitfields, the others speed up
4002 access to xdata mapped I/O devices.
4004 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
4006 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4008 Cleaned up genPackBits and genUnpackBits and added two helper
4009 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
4010 for literal assignments in genPackBits (thanks to Frieder for
4016 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4018 Fixed bug #748310 (pointer to function type mishandled when the
4019 function name is omitted). Also fixed a SIGSEGV when a function
4020 attribute (reentrant, etc) is used on a non-function or on a
4021 function but misplaced before the parameter list.
4023 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
4025 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
4026 * support/Util/SDCCerr.h,

4048 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4050 Made the constant following the "interrupt" keyword optional. If
4051 omitted, the function will not automatically be given an entry
4052 in the interrupt vector table (similar to #pragma NOIV, but
4053 less syntacticly kludgy). The interrupt number is also now
4054 range checked. Also fixed a bug in the high order bit example

4068 * src/SDCCicode.c (operandOperation): rewritten some ops
4069 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
4070 * src/SDCCsymt.c (computeType): literals are handled the same way as any
4072 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
4073 be re-activated by defining REDUCE_LITERALS)
4074 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
4075 unsigned, but are signed by default
4076 * src/SDCCval.c (constVal): rearranged
4077 * src/SDCCval.c (valMod): preliminary fix
4078 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4120 constants are unsigned; added recognition of "u" flag for unsigned
4121 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
4122 * src/SDCCval.c (valDiv, valMod): fixed signdness
4123 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
4124 signedness of modulo, left and right shift

4583 * src/SDCCmain.c: linkOptions is changed to set *,
4584 added if/endif conditional macros to remove options help
4585 messages from optionsTable when a port is not configured, added
4586 support for the PIc16 port in the ports table, when executing
4587 the compiler with no port specified on command line, a default
4588 port is selected with the new macro DEFAULT_PORT which is
4589 defined in port.h, in setDefaultOptions() linkOptions is removed
4590 from initialization assignment, since now it is a set,
4591 parseCmdLine uses setParseWithComma for linkOptions, in
4592 linkEdit() linkOptions are accessed with new function indexSet()
4593 which returns the i'th item of a set variable. See SDCCset.c, in
4594 linkEdit() when calling buildCmdLine(), added linkOptions as
4595 last argument. Now users can pass arguments to gplink via the
4596 -Wl option, main() uses pic16glue() to glue up pic16 programs

4608 * src/pic16/glue.c: commented out some error producing lines
4609 * src/pic16/main.c: __config directives are commented out to stop
4610 gpasm complaining and test the linkage with gplink, _linkCmd and
4611 _asmCmd changed to be more gplink and gpasm friendly
4612 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4613 produced an error when parsed, peep rule 12 is added to utilize
4614 movff, but it is commented out since the pCode does not support
4615 yet a command with 2 address arguments
4617 2003-05-18 <johan AT balder>
4619 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4646 2003-05-11 Borut Razem <borut.razem AT siol.net>
4648 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4649 the path of bin directory, so that PATH is the only env. variable, which has to be set
4650 in case of standard installation.
4651 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5708 added aopGetUsesAcc() function to allow binary operators to
5709 fetch their operands in the correct order; made genMinus() emit
5710 compact code for X = LITERAL - Y
5712 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5713 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5714 sprintf() in line 1267.
5716 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5717 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5720 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5721 Changes to aslink (All the changes are marked with 'JCF'):
5723 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5726 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5727 area BSEG. Also moves, if possible, the DATA area down into the internal
5728 ram so more space is available.
5730 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5733 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5734 not bytes. Function summary() which creates a memory usage summary
5735 file with extension .mem. Reports of overlaping stack and small stack
5736 size. If the space for the stack is less than 16 bytes aslink trows a
5739 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5740 the 8051. Option 'y' for memory summary output file.
5742 Changes to sdcc (All the changes are marked with 'JCF'):
5744 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5746 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5747 overlaying area for it (uses RegBankUsed[4]).
5749 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5750 bank zero as used by default. By default aslink locates the stack
5751 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5752 the creation of the .mem file. Delegates the allocation of data area
5753 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5754 the begining of the stack area to aslink.
5756 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5757 glue() in SDCCglue.c creates an area for it.
5759 2002-09-03 Borut Razem <borut.razem AT siol.net>
5760 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5761 sdcc/src/pic/glue.c:
5762 introduced atexit() handler for teporay files removal in case of
5763 errors, assertions, ...
5765 2002-08-29 Borut Razem <borut.razem AT siol.net>
5766 * sdcc/support/cpp2/auto-host_vc_in.h:
5767 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5768 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5769 Maybe there is a similar problem with BORLANDC? It should be checked!
5771 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5772 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5773 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5774 was not executed, and the compiler (cl) launched a warning:
5775 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5777 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5778 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5780 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5781 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5783 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5784 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5785 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5786 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5787 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5788 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5789 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5790 - added Release configuration in VS projects
5791 - review of compiler an linker options
5792 - VC .exe files are generated in bin_vc directory, not to interfere
5793 with binaries generated from other projects (cygwin, mingw, bcc ...)
5795 * sdcc/src/yacc.dsp: added
5797 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5798 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5799 and insert the version number definitions from .version
5801 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5803 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5804 added - genarate auto-host.h using auto-host_vc_in.h as template
5807 removed from CVS, generated automatically
5809 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5810 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5812 2002-08-11 Borut Razem <borut.razem AT siol.net>
5813 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5815 2002-08-10 Borut Razem <borut.razem AT siol.net>
5816 * src/SDCCmain.c (main):
5817 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5818 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5819 The consequence was that some temporary files were not removed.
5822 unification of code in functions tempfilename() and tempfile():
5823 function tempnam() is defined in Visual Studio 6.0 and .NET
5825 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5827 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5828 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5829 - removed compiler command line option /WX: Treats all warnings as errors
5830 - update a list of source files, included into the project
5832 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5833 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5834 changed project type to Generic Project so that can be correcly converted to VS.NET project
5836 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5838 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5840 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5842 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5843 added return 0 statements after assert() to make compiler happy
5845 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5846 added newline in the def file to keep MSC compiler satisfied
5848 * sdcc/src/z80/gen.c:
5849 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5850 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5851 - solved MSC error in function aopDump()
5853 * sdcc_vc.h: define PREFIX as "\\sdcc"
5855 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5856 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5859 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
5860 - Rewrote the register banking algorithm.
5861 - Added pCode live-range analysis to registers (for now, only non-used and
5862 singly-used registers optimized away)
5864 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

5895 2002-03-28 Johan Knol <johan AT balder>
5897 * src/SDCCval.c: fixed bug #532436
5899 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5901 Added "char *Processor" field to the port structure.
5904 Added -p option. Allows port dependent processor to be specified.
5907 Initialized the new field char *Processor field to NULL in all ports
5910 Compiler generated registers for interrupt context saving
5911 were not getting allocated.
5913 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5916 Fixed left shift. Will promote the left side of a left shift
5917 if a) left shifting more than size of operand or b) when assigned
5918 to something size > size of left side
5920 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5922 tons of changes. Register allocation has been
5923 rewritten. Added customization for the various PICs. Flow

6028 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
6030 * sdcc/src/SDCCloop.c:
6031 Previous fix was not good. basic blocks that have "break" or "return" are
6032 not really partof a loop , but live ranges used in these blocks should
6033 be live thru the entire loop, so set partOfLoop but don't add them to
6036 2002-02-21 <johan AT FRIJA>
6038 * src/SDCCcse.c: fixed bug #514308
6040 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
6043 Fixed BUG #519583. If a conditional block ended in a return/break
6044 statement inside a loop, it was not being considered part of the loop.
6046 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
6048 2002-02-10 Karl Bongers <karl AT turbobit.com>
6051 Fixed up SDCDB debugger somewhat. Updated debugger/README
6052 with lots of comments and notes.
6054 * device/examples/test2.c:
6055 Fix bug, "red" variable not being initialized(compiler complained).
