598 Adding support for replacing ljmps with sjmps in jumptables
599 generated for switch statements. For now you need to set the
600 environment variable SDCC_SJMP_JUMPTABLE to enable this.
601 Now 4 algorithms for mcs51 jumptable generation are used:
602 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

634 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
636 * added libc directory. The current version of LibC contains string
637 functions, ctype functions and macros and some functions of the
638 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
639 be extensively tested in the future. Standard disclaimer here.
640 Library is not automatically build yet. But one can build it by
641 invoking 'make' inside the libc directory.

654 special compare&skip instructions. Initial tests fail some times
655 with variables grater than 1 byte in size, so new code is disabled,
656 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
658 * (genCast): began a fix to optimize the casting of a bit to another
659 bit, now assigning a bitfield to another bitfield will fail, sorry,

3570 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
3572 Fixed promotion, it should be done on AST level:
3573 * src/SDCCast.c (addCast): added promotion to int
3574 (decorateType): updated call to upCast()
3575 * src/SDCCicode.c (geniCodeLeftShift): removed call to
3576 usualUnaryConversions()
3578 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
3580 * support/regression/tests/literalop.c (mulWrapper): Added a
3581 wrapper to remove integer overflow warnings.

3585 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
3588 * support/regression/generate-cases.py (main): Changed from inline
3591 * doc/Makefile (install): Changed to depth first to get rid of
3592 missing directory install warning.
3594 * as/Makefile (install-doc): Made work on Mac.
3596 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
3598 * src/SDCCast.c: added an additional type flow in decorateType() of
3599 opposite direction, see feature request #860006; it's enabled at runtime
3600 by setting the environment variable SDCC_NEWTYPEFLOW
3601 * src/SDCCast.h: changed prototype of decorateType()
3602 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
3603 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
3604 'char' to 'int' can be omitted, if both operands are 'unsigned char';
3605 see feature request #877103
3606 * src/SDCCval.c: updated call of decorateType()
3607 (valBitwise): fixed bug #882876
3608 (valMinus): added promotion
3609 (valLogicAndOr): result is unsigned
3610 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
3611 * src/SDCCsymt.c (computeType),
3612 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
3613 must not cause an unsigned operation

3634 * src/pic/ralloc.h: applied patch from Slade Rich;
3635 added support for multiple code pages and multiple RAM banks on the
3636 PIC 14 port. The ASM files now no longer simply assume all the
3637 code / RAM are in the same page / bank. This means the linker can
3638 safely allocate code/RAM of separate ASM files to different pages/banks.
3639 * doc/sdccman.lyx: added Slade's tips
3640 * src/mcs51/peeph.def: fixed bug #880768

3652 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
3653 strtof is not part of C89 and isn't included with Mac OS X.
3655 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3657 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

3682 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3684 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3685 loaded with the linker search paths (-L arguments) and the libraries
3686 to be linked with the current source (-l arguments). Changes
3687 currently will affect only the pic16 port.
3688 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3689 include path the port specific paths and port specific libraries,
3690 * gplink command now contains the $3 argument,
3691 * src/pic16/device.h,
3692 * src/pic16/device.c,: structure PIC_device is made public and
3693 renamed to PIC16_device, the same for variable Pics which is renamed

3708 Documenting changes from previous commits.
3709 * configure.in (version 1.56),
3710 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3711 when generating output files to configure the pic16 library,
3712 but now I've commented it out, since gputils aren't installed in the
3713 SF compile farm, so library won't compile
3715 * device/lib/Makefile.in (version 1.56): initially I've added in
3716 target 'all' the prerequestive 'model-pic16' so it compiled the
3717 pic16 library, but now I've commented it out for the same reasons
3719 * added targets 'model-pic16' and 'objects-pic16' to compile the
3721 * added target 'port-specific-objects-pic16' to handle the
3722 generated libraries and copy them into the build/ directory
3723 * added target 'clean-intermediate-pic16' to clean intermediate
3724 files into pic16 directory
3725 * in target 'installdirs' added line to create directory pic16 in
3726 the installation path
3728 * device/include/Makefile.in (version 1.11): in target 'install'
3729 added lines to copy all header files to installation path,
3730 * in target 'installdirs' added line create directory for pic16
3731 headers in the installation path

3746 * src/z80/main.c (_parseOptions): fixed the portmode= command line
3747 option so that it actually works. Made it specific to the z80, since
3748 the gbz80 doesn't have these kinds of I/O ports.
3750 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3752 * device/include/z180.h,

3776 via literal number. The symbol is placed in the corresponding
3777 position of the data ram
3778 * (pic16_dump_section): relocatable and absolute uninitialized
3779 data are now emitted in sorted order to reduce section naming,
3780 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3781 weren't marked as being in the access bank,
3783 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3785 Added portion of GNU PIC Library under the directory
3786 device/include/pic16 and device/lib/pic16. These files
3787 contain the declarations of SFRs for the PIC18Fxx2 devices.
3788 The directory is initialized via configure from toplevel.

3818 all over. Telling LaTeX to be less strict with word spacing
3819 to better keep the right margin. Changed some notes about
3820 maintainance of the ports in section 3.2.1 - is it OK like this?
3822 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

3862 * src/pic16/peeph.def: all peepholes with movff are commented out,
3863 because there is a problem in the pcode peep optimizer,
3864 * src/pic16/ralloc.c: the register allocator can now reuse local

4003 Bug reported from Jesus Calvino-Fraga
4005 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4007 * sdcc.spec: updated
4008 * device/include/Makefile.in: don't install CVS directories

4016 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4018 PIC16 port related changes:
4019 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4020 added variable stackPos,
4022 * gen.c: genCall, assignResultValue: added support for
4023 pushing/retrieving function parameters to/from stack,
4024 genFunction,genEndFunction: setup stack frame for the
4026 genAddrOf: will be changed according to bug 863624
4028 * added files genutils.c and genutils.h which contain gen*
4029 debugged and optimised functions extracted from gen.c
4031 * glue.c: added variable 'externs' which holds extern symbols,
4032 pic16emitRegularMap: is modified to properly handle relocatable
4033 symbols under the new scheme,
4034 pic16createInterruptVect: is modified
4035 pic16printPublics: is modified to emit 'global' assembler directives,
4036 added pic16_printExterns to print extern symbols,
4037 pic16glue: initializes stack/frame pointer in the beginning of
4038 the assembly output. Temporary hack, will be corrected later,
4039 because gplink yet does not support stack and SDCC does not
4040 yet support a type of crt0.o object to create the final binary.
4042 * Removed many lines that contain 8051 legacy code.
4043 * The code is finally placed under a 'code' directive.
4044 * Added port specific options.
4046 * _process_pragma: simplified since now we do not need *special*
4047 include file to define SFR registers. But a separate header
4048 will be needed. This will be developed later.
4049 * _pic16_parseOptions: added, parses port specific options:
4050 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4051 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4052 --preplace-udata-with=
4054 * _pic16_setDefaultOptions: modified to initialize section names,
4055 but hack is temporarly out of order since it needs improvement.
4056 * _pic16_genAssemblerPreamble: configuration words are emitted by
4057 their address instead of their name. This part is incomplete and
4058 supports only the 18Fxx2 devices. Other devices will emit an error
4059 during assembly since they do not contain the same set of config
4061 * _pic16_genIVT: is modified,
4063 * pcode.c: added definitions for some hardware registers that are needed
4065 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4066 All PCI entries are updated. Now LFSR is supported.
4067 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4068 * added pic16_newpCodeOpLit2 to support instructions with
4069 two literal arguments
4070 * pic16_pCode2str: corrected code that emits assembler instructions
4071 with two literal operands and those that have an access bit modifier
4072 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4073 this fixes a bug which caused some labels to be lost, when an
4074 assembler directive was added, i.e. banksel,
4075 * pic16_FixRegisterBanking: improved logic that causes the insertion
4077 * InlineFunction: functions that are called once, are not any more
4078 inlined. This can be a port option in the future,
4080 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4082 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4083 hold the corresponding uninitialized symbols,
4084 * pic16_allocProcessorRegister: registers have explicit marked the
4086 * pic16_allocInternalRegister: registers are explicit marked as
4088 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4089 processing list, so bit registers were lost,
4092 * ralloc.h: added field 'accessBank' and original symbol operand
4093 in register definition,
4094 * removed the field isMapped from register definition,
4096 ** Several functions have been removed from various sources:
4097 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4098 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4099 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4100 pic16_assignRelocatableRegisters
4102 ** others have been introduced:
4103 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4104 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4106 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4108 * support/scripts/inc2h.pl: changed definition of BIT_AT
4109 to emit 'sbit at' instead of 'bit at'. This was a request.
4111 PIC16 port related preliminary changes:
4112 * gen.c: prefixed function popRegFromString with
4113 pic16_ and all references to it corrected
4114 * pcode.c: all pic16_pc_* hardware registers prefixed
4115 with underscore (_),
4116 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4117 * ralloc.c: newReg(): when register is REG_SFR then
4118 set address to rIdx,
4119 pic16_allocProcessorRegister(): marks register wasUsed=0
4120 pic16_writeUsedRegs(): added a call to assign processor
4121 registers via pic16_assignFixedRegisters
4123 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4125 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4126 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4127 variables in unused register banks. Also the SSEG is placed
4128 wherever there is enough space for it, and IDATA can be anywhere
4129 in internal RAM. For now compile using -Wl-Y[stack_size].
4130 The mem file is different for this option as well, since it
4131 makes no sense of talking about DSEG lenght.
4133 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4135 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4136 in certain cases, e.g. when ROM assignment, patch provided
4137 from Albert den Haan.

4380 * src/SDCCast.c (decorateType): disabled a transformation I added in
4381 revision 1.188 (access to fields of a structure at an absolute address);
4382 it breaks with bitfields, extern declarations, and gcse analysis.
4383 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4384 could be assigned through a pointer, so don't complain.

4492 xdata initialization slightly shorter
4494 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5143 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5144 copied from genNearPointerSet()
5145 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5146 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5147 If they pop r0/r1 they must be called in the opposite order than aopOp().
5148 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"

5162 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5163 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5164 type for bits was changed. It resulted in bit variables becoming
5165 global, which is not permitted in PIC 14 assembly output.
5167 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5169 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5182 A few small changes that speed up the peephole optimizer.
5186 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5188 Try to make the peephole optimizer smarter by maintaining
5189 an association between the assembly source code and the
5190 iCodes that originated them. Put this information to use
5191 with a new peephole rule condition "notVolatile" so that
5192 the rules can be aggressive yet still safe.
5197 * src/mcs51/peeph.def
5199 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5203 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5204 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5205 if the left or right operand symbols have the accuse flag set.
5207 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5209 Changed the type of the result of the ! (NOT) operator to char;
5210 previously it returned the same type as the source. This allows
5211 us to eliminate all the genFloatNot functions (all of its target
5212 implementations were very buggy) since !float can use the same
5215 * src/SDCCicode.c (ast2iCode): ! returns char

5217 * src/ds390/gen.c (genNot, genNotFloat),
5218 * src/z80/gen.c (genNot, genNotFloat),
5219 * src/pic/gen.c (genNot, genNotFloat),

5224 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5225 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5226 during interrupts. Ensure WSAVE is located at a shared bank address.
5227 2. Fixed page selection in some places
5228 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5229 the registers name strings.
5230 4. Fixed "signed / unsigned compare" compiler warnings.
5231 5. The PIC port manages its own allocation of the general purpose
5232 registers, but makes no attempt to reuse them. As a result when
5233 compiling it soon runs out of general purpose registers. Some
5234 additional code was added to the files pcode.c and device.c to walk
5235 through the function call tree and rename the registers so that they
5245 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5246 genPlus() & genMinus() when the result is the same as left or right
5248 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5252 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5254 Made bitfield a distinct type from bit so that bitfields
5255 convert as per ANSI C and bits retain their traditional
5256 boolean style behaviour. Implemented bitfield support in
5264 * src/ds390/gen.c: bit v bitfield split
5265 * src/z80/gen.c: New support for bitfields
5266 * support/regression/tests/bitfields.c: reenabled z80,
5269 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5271 Rules 246.x, 247.x relate to bitfields, the others speed up
5272 access to xdata mapped I/O devices.
5274 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5276 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5278 Cleaned up genPackBits and genUnpackBits and added two helper
5279 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5280 for literal assignments in genPackBits (thanks to Frieder for
5286 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5288 Fixed bug #748310 (pointer to function type mishandled when the
5289 function name is omitted). Also fixed a SIGSEGV when a function
5290 attribute (reentrant, etc) is used on a non-function or on a
5291 function but misplaced before the parameter list.
5293 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5295 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5296 * support/Util/SDCCerr.h,
5297 * support/Util/SDCCerr.c: Added func attr misuse error msg

5318 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5320 Made the constant following the "interrupt" keyword optional. If
5321 omitted, the function will not automatically be given an entry
5322 in the interrupt vector table (similar to #pragma NOIV, but
5323 less syntacticly kludgy). The interrupt number is also now
5324 range checked. Also fixed a bug in the high order bit example
5331 * support/Util/SDCCerr.c
5332 * support/Util/SDCCerr.h
5335 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

5338 * src/SDCCicode.c (operandOperation): rewritten some ops
5339 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5340 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5342 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5343 be re-activated by defining REDUCE_LITERALS)
5344 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5345 unsigned, but are signed by default
5346 * src/SDCCval.c (constVal): rearranged
5347 * src/SDCCval.c (valMod): preliminary fix
5348 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5390 constants are unsigned; added recognition of "u" flag for unsigned
5391 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5392 * src/SDCCval.c (valDiv, valMod): fixed signdness
5393 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5394 signedness of modulo, left and right shift

5445 Messed up 'configure', so revert to previous version:
5449 2003-07-31 Bernhard Held <bernhard AT bernhardheld.de>
5451 * src/SDCCicode.c (operandOperation): 3. fix, this time for Alpha; ULONG has 64 bits

5803 Using pdflatex this will give you a hyperlinked pdf file with
5804 bookmarks. (prepend '%' before /usepackage if this breaks something)

5853 * src/SDCCmain.c: linkOptions is changed to set *,
5854 added if/endif conditional macros to remove options help
5855 messages from optionsTable when a port is not configured, added
5856 support for the PIc16 port in the ports table, when executing
5857 the compiler with no port specified on command line, a default
5858 port is selected with the new macro DEFAULT_PORT which is
5859 defined in port.h, in setDefaultOptions() linkOptions is removed
5860 from initialization assignment, since now it is a set,
5861 parseCmdLine uses setParseWithComma for linkOptions, in
5862 linkEdit() linkOptions are accessed with new function indexSet()
5863 which returns the i'th item of a set variable. See SDCCset.c, in
5864 linkEdit() when calling buildCmdLine(), added linkOptions as
5865 last argument. Now users can pass arguments to gplink via the
5866 -Wl option, main() uses pic16glue() to glue up pic16 programs

5878 * src/pic16/glue.c: commented out some error producing lines
5879 * src/pic16/main.c: __config directives are commented out to stop
5880 gpasm complaining and test the linkage with gplink, _linkCmd and
5881 _asmCmd changed to be more gplink and gpasm friendly
5882 * src/pic16/peeph.def: peep rule 3 is commented out, since it
5883 produced an error when parsed, peep rule 12 is added to utilize
5884 movff, but it is commented out since the pCode does not support
5885 yet a command with 2 address arguments
5887 2003-05-18 <johan AT balder>
5889 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

5916 2003-05-11 Borut Razem <borut.razem AT siol.net>
5918 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
5919 the path of bin directory, so that PATH is the only env. variable, which has to be set
5920 in case of standard installation.

6987 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
6990 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6991 Changes to aslink (All the changes are marked with 'JCF'):
6993 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
6996 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
6997 area BSEG. Also moves, if possible, the DATA area down into the internal
6998 ram so more space is available.
7000 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7003 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7004 not bytes. Function summary() which creates a memory usage summary
7005 file with extension .mem. Reports of overlaping stack and small stack
7006 size. If the space for the stack is less than 16 bytes aslink trows a
7009 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7010 the 8051. Option 'y' for memory summary output file.
7012 Changes to sdcc (All the changes are marked with 'JCF'):
7014 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7016 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7017 overlaying area for it (uses RegBankUsed[4]).
7019 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7020 bank zero as used by default. By default aslink locates the stack
7021 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7022 the creation of the .mem file. Delegates the allocation of data area
7023 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7024 the begining of the stack area to aslink.
7026 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7027 glue() in SDCCglue.c creates an area for it.
7029 2002-09-03 Borut Razem <borut.razem AT siol.net>
7030 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7031 sdcc/src/pic/glue.c:
7032 introduced atexit() handler for teporay files removal in case of
7033 errors, assertions, ...
7035 2002-08-29 Borut Razem <borut.razem AT siol.net>
7036 * sdcc/support/cpp2/auto-host_vc_in.h:
7037 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7038 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7039 Maybe there is a similar problem with BORLANDC? It should be checked!
7041 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7042 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7043 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7044 was not executed, and the compiler (cl) launched a warning:
7045 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7047 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7048 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7050 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7051 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7053 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7054 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7055 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7056 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7057 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7058 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7059 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7060 - added Release configuration in VS projects
7061 - review of compiler an linker options
7062 - VC .exe files are generated in bin_vc directory, not to interfere
7063 with binaries generated from other projects (cygwin, mingw, bcc ...)
7065 * sdcc/src/yacc.dsp: added
7067 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7068 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7069 and insert the version number definitions from .version
7071 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7073 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7074 added - genarate auto-host.h using auto-host_vc_in.h as template
7077 removed from CVS, generated automatically
7079 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7080 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7082 2002-08-11 Borut Razem <borut.razem AT siol.net>
7083 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7085 2002-08-10 Borut Razem <borut.razem AT siol.net>
7086 * src/SDCCmain.c (main):
7087 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7088 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7089 The consequence was that some temporary files were not removed.
7092 unification of code in functions tempfilename() and tempfile():
7093 function tempnam() is defined in Visual Studio 6.0 and .NET
7095 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7097 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7098 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7099 - removed compiler command line option /WX: Treats all warnings as errors
7100 - update a list of source files, included into the project
7102 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7103 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7104 changed project type to Generic Project so that can be correcly converted to VS.NET project
7106 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7108 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7110 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7112 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7113 added return 0 statements after assert() to make compiler happy
7115 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7116 added newline in the def file to keep MSC compiler satisfied
7118 * sdcc/src/z80/gen.c:
7119 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7120 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7121 - solved MSC error in function aopDump()
7123 * sdcc_vc.h: define PREFIX as "\\sdcc"
7125 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7126 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7174 Added -p option. Allows port dependent processor to be specified.
7177 Initialized the new field char *Processor field to NULL in all ports
7180 Compiler generated registers for interrupt context saving
7181 were not getting allocated.
7183 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7186 Fixed left shift. Will promote the left side of a left shift
7187 if a) left shifting more than size of operand or b) when assigned
7188 to something size > size of left side
7190 2002-03-14 Scott Dattalo <scott AT dattalo.com>

7298 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7300 * sdcc/src/SDCCloop.c:
7301 Previous fix was not good. basic blocks that have "break" or "return" are
7302 not really partof a loop , but live ranges used in these blocks should
7303 be live thru the entire loop, so set partOfLoop but don't add them to
7306 2002-02-21 <johan AT FRIJA>
7308 * src/SDCCcse.c: fixed bug #514308
7310 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

7314 statement inside a loop, it was not being considered part of the loop.
7316 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7318 2002-02-10 Karl Bongers <karl AT turbobit.com>
7321 Fixed up SDCDB debugger somewhat. Updated debugger/README
7322 with lots of comments and notes.
7324 * device/examples/test2.c:
7325 Fix bug, "red" variable not being initialized(compiler complained).
