3 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4 moved to level 0 and declared as static. Also they are explicit
5 placed in access bank. This was necessery because some times they
6 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
7 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
8 optimizations. Currently only compare to unsigned char is implemented,
9 * src/pic16/gen.c: added fReturnIdx array,
10 * (struct resolvedIfx) is moved to gen.h and made public,
11 * (struct _G): added sregsAlloc and sregsAllocSet fields,
12 * (aopForSym): added an optimization to directly store in stack of
13 the operand of a SEND iCode,
14 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
15 but as registers instead (AOP_REG) using the fReturnIdx array,
16 * (pic16_freeAsmop): remove the freed register from the
18 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
20 * (pic16_popGetTempRegCond): changed function prototype, now
21 function takes also a bitVector argument v which holds the current
22 set of registers that are allocated for stack access by aopForSym,
23 registers allocated in aopForSym for accessing stack symbols are not
24 any more part of the functions usedRegs field,
25 * (genCall): some times aopOp is called for a stack variable to be
26 send, aopForSym might perform the push, if this is true make sure
27 that genCall doesn't push the variable twice by testing _G.resDirect,
28 * (genFunction): changed testing for unspecified interrupt number
29 from 256 to INTNO_UNSPEC,
30 * modified selection scheme of frame pointer generation. Previously
31 if function did use local registers a frame pointer was generated,
32 now a frame pointer is generated only if function has arguments
33 (that need PLUSW2 register access), or has stack arguments, or the
34 compiler is not instructed to omit the frame pointer,
35 * (genEndFunction): before restoring local registers that were saved
36 in the function preamble, also restore the registers that *might*
37 have been allocated for stack access,
38 * (genRet): removed some old comments,
39 * (genCmp, the active (RN's) version): added a call to the
40 pic16_genCmp_special function to perform the compare with a more
41 robust and optimized way,
42 * (genInline): a feature has been added in inline code generation,
43 which allows a wildcard variable substitution when writing inline
44 assembly. Code is incomplete and experimental therefore undocumented,
45 * (genCast): changed order of aopOp for result and right to allow
46 aopForSym to directly load the result if possible,
47 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
48 perform an optimized compare on some selected special occasions,
49 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
50 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
51 generate an IVT any more,
52 * src/pic16/main.c (pic16_optionsTable): added command line option
54 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
55 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
57 * src/pic16/NOTES: Raphael Neider added in list of active developers
58 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
59 jumptable_end to prevent bug #,
60 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
61 inCond and outCond fields,
62 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
63 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
64 turn off register spilling,
65 * (packRegsForOneUse): synced with other ports' versions although it
66 is not used currently,
67 * (pic16_packRegisters): added an optimization while reading
68 structure bitfields, some registers may be saved (malloc code is
69 decreased by 80 bytes)
71 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
73 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
74 left is a bitfield, if yes, then don't optimize assignment. Perhaps
75 this can be optimized more?
77 2005-03-10 Raphael Neider <rneider AT web.de>
79 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
80 genNearPointerGet): (hopefully) fixed access to bitfields via
81 pointers (p->bitN = x; and x = p->bitN; failed)
83 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

773 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
775 * (genCast): began a fix to optimize the casting of a bit to another
776 bit, now assigning a bitfield to another bitfield will fail, sorry,

3802 loaded with the linker search paths (-L arguments) and the libraries
3803 to be linked with the current source (-l arguments). Changes
3804 currently will affect only the pic16 port.
3805 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3806 include path the port specific paths and port specific libraries,
3807 * gplink command now contains the $3 argument,
3808 * src/pic16/device.h,
3809 * src/pic16/device.c,: structure PIC_device is made public and

3825 Documenting changes from previous commits.
3826 * configure.in (version 1.56),
3827 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3828 when generating output files to configure the pic16 library,
3829 but now I've commented it out, since gputils aren't installed in the
3830 SF compile farm, so library won't compile
3832 * device/lib/Makefile.in (version 1.56): initially I've added in
3833 target 'all' the prerequestive 'model-pic16' so it compiled the
3834 pic16 library, but now I've commented it out for the same reasons
3836 * added targets 'model-pic16' and 'objects-pic16' to compile the
3838 * added target 'port-specific-objects-pic16' to handle the
3839 generated libraries and copy them into the build/ directory
3840 * added target 'clean-intermediate-pic16' to clean intermediate
3841 files into pic16 directory
3842 * in target 'installdirs' added line to create directory pic16 in

4087 * src/SDCCast.c (decorateType),
4088 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
4089 LEFT_OP (left shift)
4091 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4093 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4094 (default behaviour).
4096 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4098 A python script to validate compiler diagnostic messages. It can be
4099 used to verify that sdcc complains about bad c source code and
4100 gives a good location of the error.
4101 * support/valdiag/Makefile,
4102 * support/valdiag/valdiag.py,
4103 * support/valdiag/tests/*
4105 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4116 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4118 * src/common.h: added ifndef/define/endif macros
4119 around the header file.
4120 Bug reported from Jesus Calvino-Fraga
4122 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4124 * sdcc.spec: updated
4125 * device/include/Makefile.in: don't install CVS directories
4126 * device/lib/Makefile.in: added removal of CVS directories after install
4127 * doc/Makefile: fixed install, added local_icons
4128 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4129 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4130 * src/ds390/gen.c (genRightShift): fixed bug #870788
4131 * src/SDCCast.c (decorateType): fixed bug #870781
4133 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4135 PIC16 port related changes:
4136 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4137 added variable stackPos,
4139 * gen.c: genCall, assignResultValue: added support for
4140 pushing/retrieving function parameters to/from stack,
4141 genFunction,genEndFunction: setup stack frame for the
4143 genAddrOf: will be changed according to bug 863624
4145 * added files genutils.c and genutils.h which contain gen*
4146 debugged and optimised functions extracted from gen.c
4148 * glue.c: added variable 'externs' which holds extern symbols,
4149 pic16emitRegularMap: is modified to properly handle relocatable
4150 symbols under the new scheme,
4151 pic16createInterruptVect: is modified
4152 pic16printPublics: is modified to emit 'global' assembler directives,
4153 added pic16_printExterns to print extern symbols,
4154 pic16glue: initializes stack/frame pointer in the beginning of
4155 the assembly output. Temporary hack, will be corrected later,
4156 because gplink yet does not support stack and SDCC does not
4157 yet support a type of crt0.o object to create the final binary.
4159 * Removed many lines that contain 8051 legacy code.
4160 * The code is finally placed under a 'code' directive.
4161 * Added port specific options.
4163 * _process_pragma: simplified since now we do not need *special*
4164 include file to define SFR registers. But a separate header
4165 will be needed. This will be developed later.
4166 * _pic16_parseOptions: added, parses port specific options:
4167 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4168 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4169 --preplace-udata-with=
4171 * _pic16_setDefaultOptions: modified to initialize section names,
4172 but hack is temporarly out of order since it needs improvement.
4173 * _pic16_genAssemblerPreamble: configuration words are emitted by
4174 their address instead of their name. This part is incomplete and
4175 supports only the 18Fxx2 devices. Other devices will emit an error
4176 during assembly since they do not contain the same set of config
4178 * _pic16_genIVT: is modified,
4180 * pcode.c: added definitions for some hardware registers that are needed
4182 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4183 All PCI entries are updated. Now LFSR is supported.
4184 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4185 * added pic16_newpCodeOpLit2 to support instructions with
4186 two literal arguments
4187 * pic16_pCode2str: corrected code that emits assembler instructions
4188 with two literal operands and those that have an access bit modifier
4189 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4190 this fixes a bug which caused some labels to be lost, when an
4191 assembler directive was added, i.e. banksel,
4192 * pic16_FixRegisterBanking: improved logic that causes the insertion
4194 * InlineFunction: functions that are called once, are not any more
4195 inlined. This can be a port option in the future,
4197 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4199 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4200 hold the corresponding uninitialized symbols,
4201 * pic16_allocProcessorRegister: registers have explicit marked the
4203 * pic16_allocInternalRegister: registers are explicit marked as
4205 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4206 processing list, so bit registers were lost,
4209 * ralloc.h: added field 'accessBank' and original symbol operand
4210 in register definition,
4211 * removed the field isMapped from register definition,
4213 ** Several functions have been removed from various sources:
4214 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4215 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4216 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4217 pic16_assignRelocatableRegisters
4219 ** others have been introduced:
4220 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4221 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4223 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4225 * support/scripts/inc2h.pl: changed definition of BIT_AT
4226 to emit 'sbit at' instead of 'bit at'. This was a request.
4228 PIC16 port related preliminary changes:
4229 * gen.c: prefixed function popRegFromString with
4230 pic16_ and all references to it corrected
4231 * pcode.c: all pic16_pc_* hardware registers prefixed
4232 with underscore (_),
4233 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4234 * ralloc.c: newReg(): when register is REG_SFR then
4235 set address to rIdx,
4236 pic16_allocProcessorRegister(): marks register wasUsed=0
4237 pic16_writeUsedRegs(): added a call to assign processor
4238 registers via pic16_assignFixedRegisters
4240 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4242 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4243 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4244 variables in unused register banks. Also the SSEG is placed
4245 wherever there is enough space for it, and IDATA can be anywhere
4246 in internal RAM. For now compile using -Wl-Y[stack_size].
4247 The mem file is different for this option as well, since it
4248 makes no sense of talking about DSEG lenght.
4250 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4252 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4253 in certain cases, e.g. when ROM assignment, patch provided
4254 from Albert den Haan.

4495 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4497 * src/SDCCast.c (decorateType): disabled a transformation I added in
4498 revision 1.188 (access to fields of a structure at an absolute address);
4499 it breaks with bitfields, extern declarations, and gcse analysis.
4500 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4501 could be assigned through a pointer, so don't complain.
4502 * src/SDCCast.c (astErrors),
4504 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
4506 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

5142 support for standard C idiom of memory mapped variables; for
5143 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5144 to xdata int at 0x1234 tempvar = 1.

5257 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5258 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5259 fetching of the pointer
5260 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5261 copied from genNearPointerSet()
5262 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5263 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5264 If they pop r0/r1 they must be called in the opposite order than aopOp().
5265 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5266 (resp. --stack-auto), prepared for --xstack

5277 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5279 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5280 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5281 type for bits was changed. It resulted in bit variables becoming
5282 global, which is not permitted in PIC 14 assembly output.
5284 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5286 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5299 A few small changes that speed up the peephole optimizer.
5303 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5305 Try to make the peephole optimizer smarter by maintaining
5306 an association between the assembly source code and the
5307 iCodes that originated them. Put this information to use
5308 with a new peephole rule condition "notVolatile" so that
5309 the rules can be aggressive yet still safe.
5314 * src/mcs51/peeph.def
5316 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5320 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5321 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5322 if the left or right operand symbols have the accuse flag set.
5324 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5326 Changed the type of the result of the ! (NOT) operator to char;
5327 previously it returned the same type as the source. This allows
5328 us to eliminate all the genFloatNot functions (all of its target
5329 implementations were very buggy) since !float can use the same
5332 * src/SDCCicode.c (ast2iCode): ! returns char

5341 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5342 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5343 during interrupts. Ensure WSAVE is located at a shared bank address.
5344 2. Fixed page selection in some places
5345 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5346 the registers name strings.
5347 4. Fixed "signed / unsigned compare" compiler warnings.
5348 5. The PIC port manages its own allocation of the general purpose
5349 registers, but makes no attempt to reuse them. As a result when
5350 compiling it soon runs out of general purpose registers. Some
5351 additional code was added to the files pcode.c and device.c to walk
5352 through the function call tree and rename the registers so that they
5362 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5363 genPlus() & genMinus() when the result is the same as left or right

5369 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5371 Made bitfield a distinct type from bit so that bitfields
5372 convert as per ANSI C and bits retain their traditional
5373 boolean style behaviour. Implemented bitfield support in
5381 * src/ds390/gen.c: bit v bitfield split
5382 * src/z80/gen.c: New support for bitfields
5383 * support/regression/tests/bitfields.c: reenabled z80,
5386 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5388 Rules 246.x, 247.x relate to bitfields, the others speed up
5389 access to xdata mapped I/O devices.
5391 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5393 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5395 Cleaned up genPackBits and genUnpackBits and added two helper
5396 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5397 for literal assignments in genPackBits (thanks to Frieder for
5403 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5405 Fixed bug #748310 (pointer to function type mishandled when the
5406 function name is omitted). Also fixed a SIGSEGV when a function
5407 attribute (reentrant, etc) is used on a non-function or on a
5408 function but misplaced before the parameter list.
5410 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5412 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5413 * support/Util/SDCCerr.h,

5435 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5437 Made the constant following the "interrupt" keyword optional. If
5438 omitted, the function will not automatically be given an entry
5439 in the interrupt vector table (similar to #pragma NOIV, but
5440 less syntacticly kludgy). The interrupt number is also now
5441 range checked. Also fixed a bug in the high order bit example

5457 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5459 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5460 be re-activated by defining REDUCE_LITERALS)

5973 support for the PIc16 port in the ports table, when executing
5974 the compiler with no port specified on command line, a default
5975 port is selected with the new macro DEFAULT_PORT which is
5976 defined in port.h, in setDefaultOptions() linkOptions is removed
5977 from initialization assignment, since now it is a set,
5978 parseCmdLine uses setParseWithComma for linkOptions, in
5979 linkEdit() linkOptions are accessed with new function indexSet()
5980 which returns the i'th item of a set variable. See SDCCset.c, in
5981 linkEdit() when calling buildCmdLine(), added linkOptions as
5982 last argument. Now users can pass arguments to gplink via the
5983 -Wl option, main() uses pic16glue() to glue up pic16 programs

5997 gpasm complaining and test the linkage with gplink, _linkCmd and
5998 _asmCmd changed to be more gplink and gpasm friendly
5999 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6000 produced an error when parsed, peep rule 12 is added to utilize
6001 movff, but it is commented out since the pCode does not support
6002 yet a command with 2 address arguments
6004 2003-05-18 <johan AT balder>
6006 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7039 2003-01-06 <johan AT balder>
7041 * src/SDCCicode.c: fixed array add
7043 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7044 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7045 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7047 2003-01-04 <johan AT balder>
7049 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7051 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7052 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7054 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

7064 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7065 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7067 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7069 * in \sdcc\as\mcs51\ changed these files in order to create an
7070 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7071 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7072 following files to include the previous two files: aslink.dsp,
7073 Makefile.aslink, Makefile.bcc, and Makefile.in.
7075 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7076 .adb instead of .cdb
7078 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7080 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7081 value from option --iram-size.
7083 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7085 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7088 2002-09-18 <wiml AT hhhh.org>
7090 * SDCClrange.h: exposed setFromRange() and setToRange()
7091 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7092 packRegsForAccUse() (bug 542397)
7093 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7094 multiple times and emitting the fetch operations more than once
7095 added aopGetUsesAcc() function to allow binary operators to
7096 fetch their operands in the correct order; made genMinus() emit
7097 compact code for X = LITERAL - Y
7099 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7100 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7101 sprintf() in line 1267.
7103 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7104 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7107 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7108 Changes to aslink (All the changes are marked with 'JCF'):
7110 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7113 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7114 area BSEG. Also moves, if possible, the DATA area down into the internal
7115 ram so more space is available.
7117 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7120 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7121 not bytes. Function summary() which creates a memory usage summary
7122 file with extension .mem. Reports of overlaping stack and small stack
7123 size. If the space for the stack is less than 16 bytes aslink trows a
7126 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7127 the 8051. Option 'y' for memory summary output file.
7129 Changes to sdcc (All the changes are marked with 'JCF'):
7131 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7133 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7134 overlaying area for it (uses RegBankUsed[4]).
7136 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7137 bank zero as used by default. By default aslink locates the stack
7138 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7139 the creation of the .mem file. Delegates the allocation of data area
7140 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7141 the begining of the stack area to aslink.
7143 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7144 glue() in SDCCglue.c creates an area for it.
7146 2002-09-03 Borut Razem <borut.razem AT siol.net>
7147 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7148 sdcc/src/pic/glue.c:
7149 introduced atexit() handler for teporay files removal in case of
7150 errors, assertions, ...
7152 2002-08-29 Borut Razem <borut.razem AT siol.net>
7153 * sdcc/support/cpp2/auto-host_vc_in.h:
7154 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7155 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7156 Maybe there is a similar problem with BORLANDC? It should be checked!
7158 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7159 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7160 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7161 was not executed, and the compiler (cl) launched a warning:
7162 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7164 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7165 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7167 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7168 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7170 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7171 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7172 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7173 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7174 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7175 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7176 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7177 - added Release configuration in VS projects
7178 - review of compiler an linker options
7179 - VC .exe files are generated in bin_vc directory, not to interfere
7180 with binaries generated from other projects (cygwin, mingw, bcc ...)
7182 * sdcc/src/yacc.dsp: added
7184 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7185 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7186 and insert the version number definitions from .version
7188 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7190 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7191 added - genarate auto-host.h using auto-host_vc_in.h as template
7194 removed from CVS, generated automatically
7196 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7197 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7199 2002-08-11 Borut Razem <borut.razem AT siol.net>
7200 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7202 2002-08-10 Borut Razem <borut.razem AT siol.net>
7203 * src/SDCCmain.c (main):
7204 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7205 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7206 The consequence was that some temporary files were not removed.
7209 unification of code in functions tempfilename() and tempfile():
7210 function tempnam() is defined in Visual Studio 6.0 and .NET
7212 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7214 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7215 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7216 - removed compiler command line option /WX: Treats all warnings as errors
7217 - update a list of source files, included into the project
7219 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7220 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7221 changed project type to Generic Project so that can be correcly converted to VS.NET project
7223 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7225 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7227 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7229 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7230 added return 0 statements after assert() to make compiler happy
7232 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7233 added newline in the def file to keep MSC compiler satisfied
7235 * sdcc/src/z80/gen.c:
7236 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7237 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7238 - solved MSC error in function aopDump()
7240 * sdcc_vc.h: define PREFIX as "\\sdcc"
7242 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7243 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7245 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7246 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7247 - Rewrote the register banking algorithm.
7248 - Added pCode live-range analysis to registers (for now, only non-used and
7249 singly-used registers optimized away)
7251 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7253 * 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.
7255 2002-05-10 Scott Dattalo <scott AT dattalo.com>
7256 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
7258 2002-04-22 Michael Hope <michaelh AT vroom>

7278 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7280 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7282 2002-03-28 Johan Knol <johan AT balder>
7284 * src/SDCCval.c: fixed bug #532436
7286 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7288 Added "char *Processor" field to the port structure.
7291 Added -p option. Allows port dependent processor to be specified.
7294 Initialized the new field char *Processor field to NULL in all ports
7297 Compiler generated registers for interrupt context saving
7298 were not getting allocated.
7300 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7303 Fixed left shift. Will promote the left side of a left shift
7304 if a) left shifting more than size of operand or b) when assigned
7305 to something size > size of left side
7307 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7309 tons of changes. Register allocation has been
7310 rewritten. Added customization for the various PICs. Flow
7311 analysis is restructured. ...
7317 Added. device.c is a PIC port hack to accomodate variations
7320 2002-03-13 Michael Hope <michaelh AT vroom>
7322 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7324 2002-03-04 johanknol <johanknol AT manik>
7326 * /src/SDCCval.c: fixed
7328 const unsigned char arr[][2] = { { 0, 1 } };

7331 2002-03-04 bela <bela AT manik>
7333 * /device/include/mcs51reg.h:
7334 ds89c420 register definition update

7415 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7417 * sdcc/src/SDCCloop.c:
7418 Previous fix was not good. basic blocks that have "break" or "return" are
7419 not really partof a loop , but live ranges used in these blocks should
7420 be live thru the entire loop, so set partOfLoop but don't add them to
7423 2002-02-21 <johan AT FRIJA>
7425 * src/SDCCcse.c: fixed bug #514308
7427 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7430 Fixed BUG #519583. If a conditional block ended in a return/break
7431 statement inside a loop, it was not being considered part of the loop.
7433 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7435 2002-02-10 Karl Bongers <karl AT turbobit.com>
7438 Fixed up SDCDB debugger somewhat. Updated debugger/README
7439 with lots of comments and notes.
7441 * device/examples/test2.c:
7442 Fix bug, "red" variable not being initialized(compiler complained).
7444 * device/examples/Makefile, examples/test3.c:
7445 Add Makefile in device/examples folder, compiles test3.c
7446 for use as a multiple module SDCDB test case.
7448 * sim/ucsim/cmd.src/cmdset.cc:
7449 Took out debug printfs in ucsim "next" command.
7452 Karl and Johan start ucsim XA support. Most dissassembly working,
7453 about 75% emulation done(plenty of work remaining).
7455 * sim/ucsim/z80.src:
7456 Add Z80 support to ucsim, add test-ucz80 regression test,
7457 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
7458 Notice z80 compiler fails on examples/test3.c/crc code.
7460 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
