3 * src/pic16/gen.c (genSkipc): fixed semantics (execute branch
5 * (genCmp): adapted to new genSkipc semantics
6 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
7 on rIfx (genCmp was broken)
9 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
12 * src/z80/main.c (_keywords[]),
13 * src/SDCCglobal.h (struct options),
15 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
16 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
17 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
18 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
19 always available in leading double underscore form. The C99 support is
20 mostly missing, but it's a start.
21 * support/regression/tests/bug-227710.c: fixed nonconforming use of
22 reserved identifier "__data".
24 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

66 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
67 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
68 immedDom() returning wrong block; probably fixes bug #1160833)
70 2005-03-20 Borut Razem <borut.razem AT siol.net>
72 * support/scripts/inc2h.pl: WIN32 port
74 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>

100 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
102 * device/lib/printf_large.c: removed inline assembly for portability and
103 readability. Use printf_fast if speed or size are more important.
104 * src/pic16/gen.c: removed conditions around use of DEBUGpc
105 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
107 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
109 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
110 prevent compiler warning
112 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
114 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
115 moved to level 0 and declared as static. Also they are explicit
116 placed in access bank. This was necessery because some times they
117 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
118 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
119 optimizations. Currently only compare to unsigned char is implemented,
120 * src/pic16/gen.c: added fReturnIdx array,
121 * (struct resolvedIfx) is moved to gen.h and made public,
122 * (struct _G): added sregsAlloc and sregsAllocSet fields,
123 * (aopForSym): added an optimization to directly store in stack of
124 the operand of a SEND iCode,
125 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
126 but as registers instead (AOP_REG) using the fReturnIdx array,
127 * (pic16_freeAsmop): remove the freed register from the
129 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
131 * (pic16_popGetTempRegCond): changed function prototype, now
132 function takes also a bitVector argument v which holds the current
133 set of registers that are allocated for stack access by aopForSym,
134 registers allocated in aopForSym for accessing stack symbols are not
135 any more part of the functions usedRegs field,
136 * (genCall): some times aopOp is called for a stack variable to be
137 send, aopForSym might perform the push, if this is true make sure
138 that genCall doesn't push the variable twice by testing _G.resDirect,
139 * (genFunction): changed testing for unspecified interrupt number
140 from 256 to INTNO_UNSPEC,
141 * modified selection scheme of frame pointer generation. Previously
142 if function did use local registers a frame pointer was generated,
143 now a frame pointer is generated only if function has arguments
144 (that need PLUSW2 register access), or has stack arguments, or the
145 compiler is not instructed to omit the frame pointer,
146 * (genEndFunction): before restoring local registers that were saved
147 in the function preamble, also restore the registers that *might*
148 have been allocated for stack access,
149 * (genRet): removed some old comments,
150 * (genCmp, the active (RN's) version): added a call to the
151 pic16_genCmp_special function to perform the compare with a more
152 robust and optimized way,
153 * (genInline): a feature has been added in inline code generation,
154 which allows a wildcard variable substitution when writing inline
155 assembly. Code is incomplete and experimental therefore undocumented,
156 * (genCast): changed order of aopOp for result and right to allow
157 aopForSym to directly load the result if possible,
158 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
159 perform an optimized compare on some selected special occasions,
160 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
161 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
162 generate an IVT any more,
163 * src/pic16/main.c (pic16_optionsTable): added command line option
165 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
166 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
168 * src/pic16/NOTES: Raphael Neider added in list of active developers
169 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
170 jumptable_end to prevent bug #,
171 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
172 inCond and outCond fields,
173 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
174 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
175 turn off register spilling,
176 * (packRegsForOneUse): synced with other ports' versions although it
177 is not used currently,
178 * (pic16_packRegisters): added an optimization while reading
179 structure bitfields, some registers may be saved (malloc code is
180 decreased by 80 bytes)
182 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
184 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
185 left is a bitfield, if yes, then don't optimize assignment. Perhaps
186 this can be optimized more?
188 2005-03-10 Raphael Neider <rneider AT web.de>
190 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
191 genNearPointerGet): (hopefully) fixed access to bitfields via
192 pointers (p->bitN = x; and x = p->bitN; failed)
194 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
196 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

238 to keep the correct label reference count when adding/removing references
239 to labels. A peephole file using this is appended to patch #1144962.

884 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
886 * (genCast): began a fix to optimize the casting of a bit to another

3910 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3912 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3913 loaded with the linker search paths (-L arguments) and the libraries
3914 to be linked with the current source (-l arguments). Changes
3915 currently will affect only the pic16 port.
3916 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3917 include path the port specific paths and port specific libraries,
3918 * gplink command now contains the $3 argument,
3919 * src/pic16/device.h,
3920 * src/pic16/device.c,: structure PIC_device is made public and
3921 renamed to PIC16_device, the same for variable Pics which is renamed

3936 Documenting changes from previous commits.
3937 * configure.in (version 1.56),
3938 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3939 when generating output files to configure the pic16 library,
3940 but now I've commented it out, since gputils aren't installed in the
3941 SF compile farm, so library won't compile
3943 * device/lib/Makefile.in (version 1.56): initially I've added in
3944 target 'all' the prerequestive 'model-pic16' so it compiled the
3945 pic16 library, but now I've commented it out for the same reasons
3947 * added targets 'model-pic16' and 'objects-pic16' to compile the
3949 * added target 'port-specific-objects-pic16' to handle the
3950 generated libraries and copy them into the build/ directory
3951 * added target 'clean-intermediate-pic16' to clean intermediate
3952 files into pic16 directory
3953 * in target 'installdirs' added line to create directory pic16 in
3954 the installation path

3957 added lines to copy all header files to installation path,
3958 * in target 'installdirs' added line create directory for pic16
3959 headers in the installation path

3975 option so that it actually works. Made it specific to the z80, since
3976 the gbz80 doesn't have these kinds of I/O ports.
3978 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3980 * device/include/z180.h,

4004 via literal number. The symbol is placed in the corresponding
4005 position of the data ram
4006 * (pic16_dump_section): relocatable and absolute uninitialized
4007 data are now emitted in sorted order to reduce section naming,
4008 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4009 weren't marked as being in the access bank,
4011 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4013 Added portion of GNU PIC Library under the directory
4014 device/include/pic16 and device/lib/pic16. These files
4015 contain the declarations of SFRs for the PIC18Fxx2 devices.
4016 The directory is initialized via configure from toplevel.

4027 2004-01-12 Borut Razem <borut.razem AT siol.net>
4029 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
4030 doc/sdccman.lyx: upper case pragmas are deprecated
4032 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

4045 * doc/sdccman.lyx: Moved and added some sections, small changes
4046 all over. Telling LaTeX to be less strict with word spacing
4047 to better keep the right margin. Changed some notes about
4048 maintainance of the ports in section 3.2.1 - is it OK like this?
4050 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4052 SDCC source changes:
4053 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

4087 UPPER for immediate operands,
4088 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4090 * src/pic16/peeph.def: all peepholes with movff are commented out,
4091 because there is a problem in the pcode peep optimizer,
4092 * src/pic16/ralloc.c: the register allocator can now reuse local

4185 include information about variables allocated to the overlay
4188 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4190 * as/mcs51/lkmain.c: Help about -Y option

4202 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4204 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4205 (default behaviour).
4207 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4209 A python script to validate compiler diagnostic messages. It can be
4210 used to verify that sdcc complains about bad c source code and
4211 gives a good location of the error.
4212 * support/valdiag/Makefile,
4213 * support/valdiag/valdiag.py,
4214 * support/valdiag/tests/*

4230 around the header file.
4231 Bug reported from Jesus Calvino-Fraga
4233 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4235 * sdcc.spec: updated
4236 * device/include/Makefile.in: don't install CVS directories
4237 * device/lib/Makefile.in: added removal of CVS directories after install
4238 * doc/Makefile: fixed install, added local_icons
4239 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4240 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4241 * src/ds390/gen.c (genRightShift): fixed bug #870788
4242 * src/SDCCast.c (decorateType): fixed bug #870781
4244 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4246 PIC16 port related changes:
4247 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4248 added variable stackPos,
4250 * gen.c: genCall, assignResultValue: added support for
4251 pushing/retrieving function parameters to/from stack,
4252 genFunction,genEndFunction: setup stack frame for the
4254 genAddrOf: will be changed according to bug 863624
4256 * added files genutils.c and genutils.h which contain gen*
4257 debugged and optimised functions extracted from gen.c
4259 * glue.c: added variable 'externs' which holds extern symbols,
4260 pic16emitRegularMap: is modified to properly handle relocatable
4261 symbols under the new scheme,
4262 pic16createInterruptVect: is modified
4263 pic16printPublics: is modified to emit 'global' assembler directives,
4264 added pic16_printExterns to print extern symbols,
4265 pic16glue: initializes stack/frame pointer in the beginning of
4266 the assembly output. Temporary hack, will be corrected later,
4267 because gplink yet does not support stack and SDCC does not
4268 yet support a type of crt0.o object to create the final binary.
4270 * Removed many lines that contain 8051 legacy code.
4271 * The code is finally placed under a 'code' directive.
4272 * Added port specific options.
4274 * _process_pragma: simplified since now we do not need *special*
4275 include file to define SFR registers. But a separate header
4276 will be needed. This will be developed later.
4277 * _pic16_parseOptions: added, parses port specific options:
4278 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4279 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4280 --preplace-udata-with=
4282 * _pic16_setDefaultOptions: modified to initialize section names,
4283 but hack is temporarly out of order since it needs improvement.
4284 * _pic16_genAssemblerPreamble: configuration words are emitted by
4285 their address instead of their name. This part is incomplete and
4286 supports only the 18Fxx2 devices. Other devices will emit an error
4287 during assembly since they do not contain the same set of config
4289 * _pic16_genIVT: is modified,
4291 * pcode.c: added definitions for some hardware registers that are needed
4293 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4294 All PCI entries are updated. Now LFSR is supported.
4295 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4296 * added pic16_newpCodeOpLit2 to support instructions with
4297 two literal arguments
4298 * pic16_pCode2str: corrected code that emits assembler instructions
4299 with two literal operands and those that have an access bit modifier
4300 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4301 this fixes a bug which caused some labels to be lost, when an
4302 assembler directive was added, i.e. banksel,
4303 * pic16_FixRegisterBanking: improved logic that causes the insertion
4305 * InlineFunction: functions that are called once, are not any more
4306 inlined. This can be a port option in the future,
4308 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4310 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4311 hold the corresponding uninitialized symbols,
4312 * pic16_allocProcessorRegister: registers have explicit marked the
4314 * pic16_allocInternalRegister: registers are explicit marked as
4316 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4317 processing list, so bit registers were lost,
4320 * ralloc.h: added field 'accessBank' and original symbol operand
4321 in register definition,
4322 * removed the field isMapped from register definition,
4324 ** Several functions have been removed from various sources:
4325 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4326 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4327 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4328 pic16_assignRelocatableRegisters
4330 ** others have been introduced:
4331 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4332 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4334 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4336 * support/scripts/inc2h.pl: changed definition of BIT_AT
4337 to emit 'sbit at' instead of 'bit at'. This was a request.
4339 PIC16 port related preliminary changes:
4340 * gen.c: prefixed function popRegFromString with
4341 pic16_ and all references to it corrected
4342 * pcode.c: all pic16_pc_* hardware registers prefixed
4343 with underscore (_),
4344 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4345 * ralloc.c: newReg(): when register is REG_SFR then
4346 set address to rIdx,
4347 pic16_allocProcessorRegister(): marks register wasUsed=0
4348 pic16_writeUsedRegs(): added a call to assign processor
4349 registers via pic16_assignFixedRegisters
4351 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4353 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4354 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4355 variables in unused register banks. Also the SSEG is placed
4356 wherever there is enough space for it, and IDATA can be anywhere
4357 in internal RAM. For now compile using -Wl-Y[stack_size].
4358 The mem file is different for this option as well, since it
4359 makes no sense of talking about DSEG lenght.
4361 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4363 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4364 in certain cases, e.g. when ROM assignment, patch provided
4365 from Albert den Haan.
4367 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4510 * src/mcs51/peephole.def,
4511 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
4512 (allows non-interrupt and interrupt code to safely compete for a resource

5390 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5391 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5392 type for bits was changed. It resulted in bit variables becoming

5410 A few small changes that speed up the peephole optimizer.
5414 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5416 Try to make the peephole optimizer smarter by maintaining
5417 an association between the assembly source code and the
5418 iCodes that originated them. Put this information to use
5419 with a new peephole rule condition "notVolatile" so that
5420 the rules can be aggressive yet still safe.
5425 * src/mcs51/peeph.def
5427 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5431 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5432 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5433 if the left or right operand symbols have the accuse flag set.
5435 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5437 Changed the type of the result of the ! (NOT) operator to char;
5438 previously it returned the same type as the source. This allows
5439 us to eliminate all the genFloatNot functions (all of its target
5440 implementations were very buggy) since !float can use the same
5443 * src/SDCCicode.c (ast2iCode): ! returns char

5452 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5453 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5454 during interrupts. Ensure WSAVE is located at a shared bank address.
5455 2. Fixed page selection in some places
5456 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5457 the registers name strings.
5458 4. Fixed "signed / unsigned compare" compiler warnings.
5459 5. The PIC port manages its own allocation of the general purpose
5460 registers, but makes no attempt to reuse them. As a result when
5461 compiling it soon runs out of general purpose registers. Some
5462 additional code was added to the files pcode.c and device.c to walk
5463 through the function call tree and rename the registers so that they
5473 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5480 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5482 Made bitfield a distinct type from bit so that bitfields
5483 convert as per ANSI C and bits retain their traditional
5484 boolean style behaviour. Implemented bitfield support in
5492 * src/ds390/gen.c: bit v bitfield split
5493 * src/z80/gen.c: New support for bitfields
5494 * support/regression/tests/bitfields.c: reenabled z80,
5497 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5499 Rules 246.x, 247.x relate to bitfields, the others speed up
5500 access to xdata mapped I/O devices.
5502 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5504 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5506 Cleaned up genPackBits and genUnpackBits and added two helper

5516 Fixed bug #748310 (pointer to function type mishandled when the
5517 function name is omitted). Also fixed a SIGSEGV when a function
5518 attribute (reentrant, etc) is used on a non-function or on a
5519 function but misplaced before the parameter list.

5548 Made the constant following the "interrupt" keyword optional. If
5549 omitted, the function will not automatically be given an entry
5550 in the interrupt vector table (similar to #pragma NOIV, but
5551 less syntacticly kludgy). The interrupt number is also now
5552 range checked. Also fixed a bug in the high order bit example
5559 * support/Util/SDCCerr.c
5560 * support/Util/SDCCerr.h

5573 unsigned, but are signed by default
5574 * src/SDCCval.c (constVal): rearranged
5575 * src/SDCCval.c (valMod): preliminary fix
5576 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5620 * src/SDCCval.c (valDiv, valMod): fixed signdness
5621 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5622 signedness of modulo, left and right shift

6085 the compiler with no port specified on command line, a default
6086 port is selected with the new macro DEFAULT_PORT which is
6087 defined in port.h, in setDefaultOptions() linkOptions is removed
6088 from initialization assignment, since now it is a set,
6089 parseCmdLine uses setParseWithComma for linkOptions, in

7158 2003-01-04 <johan AT balder>
7160 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7162 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7163 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7165 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

7175 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7176 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7178 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7180 * in \sdcc\as\mcs51\ changed these files in order to create an
7181 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7182 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7183 following files to include the previous two files: aslink.dsp,
7184 Makefile.aslink, Makefile.bcc, and Makefile.in.
7186 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7187 .adb instead of .cdb
7189 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7191 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7192 value from option --iram-size.
7194 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7196 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7199 2002-09-18 <wiml AT hhhh.org>
7201 * SDCClrange.h: exposed setFromRange() and setToRange()
7202 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7203 packRegsForAccUse() (bug 542397)
7204 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7205 multiple times and emitting the fetch operations more than once
7206 added aopGetUsesAcc() function to allow binary operators to
7207 fetch their operands in the correct order; made genMinus() emit
7208 compact code for X = LITERAL - Y
7210 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7211 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7212 sprintf() in line 1267.
7214 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7215 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7218 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7219 Changes to aslink (All the changes are marked with 'JCF'):
7221 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7224 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7225 area BSEG. Also moves, if possible, the DATA area down into the internal
7226 ram so more space is available.
7228 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7231 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7232 not bytes. Function summary() which creates a memory usage summary
7233 file with extension .mem. Reports of overlaping stack and small stack
7234 size. If the space for the stack is less than 16 bytes aslink trows a
7237 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7238 the 8051. Option 'y' for memory summary output file.
7240 Changes to sdcc (All the changes are marked with 'JCF'):
7242 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7244 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7245 overlaying area for it (uses RegBankUsed[4]).
7247 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7248 bank zero as used by default. By default aslink locates the stack
7249 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7250 the creation of the .mem file. Delegates the allocation of data area
7251 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7252 the begining of the stack area to aslink.
7254 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7255 glue() in SDCCglue.c creates an area for it.
7257 2002-09-03 Borut Razem <borut.razem AT siol.net>
7258 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7259 sdcc/src/pic/glue.c:
7260 introduced atexit() handler for teporay files removal in case of
7261 errors, assertions, ...
7263 2002-08-29 Borut Razem <borut.razem AT siol.net>
7264 * sdcc/support/cpp2/auto-host_vc_in.h:
7265 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7266 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7267 Maybe there is a similar problem with BORLANDC? It should be checked!
7269 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7270 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7271 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7272 was not executed, and the compiler (cl) launched a warning:
7273 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7275 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7276 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7278 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7279 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7281 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7282 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7283 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7284 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7285 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7286 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7287 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7288 - added Release configuration in VS projects
7289 - review of compiler an linker options
7290 - VC .exe files are generated in bin_vc directory, not to interfere
7291 with binaries generated from other projects (cygwin, mingw, bcc ...)
7293 * sdcc/src/yacc.dsp: added
7295 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7296 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7297 and insert the version number definitions from .version
7299 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7301 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7302 added - genarate auto-host.h using auto-host_vc_in.h as template
7305 removed from CVS, generated automatically
7307 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7308 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7310 2002-08-11 Borut Razem <borut.razem AT siol.net>
7311 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7313 2002-08-10 Borut Razem <borut.razem AT siol.net>
7314 * src/SDCCmain.c (main):
7315 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7316 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7317 The consequence was that some temporary files were not removed.
7320 unification of code in functions tempfilename() and tempfile():
7321 function tempnam() is defined in Visual Studio 6.0 and .NET
7323 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7325 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7326 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7327 - removed compiler command line option /WX: Treats all warnings as errors
7328 - update a list of source files, included into the project
7330 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7331 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7332 changed project type to Generic Project so that can be correcly converted to VS.NET project
7334 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7336 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7338 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7340 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7341 added return 0 statements after assert() to make compiler happy
7343 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7344 added newline in the def file to keep MSC compiler satisfied
7346 * sdcc/src/z80/gen.c:
7347 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7348 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7349 - solved MSC error in function aopDump()
7351 * sdcc_vc.h: define PREFIX as "\\sdcc"
7353 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7354 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7356 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7357 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7358 - Rewrote the register banking algorithm.
7359 - Added pCode live-range analysis to registers (for now, only non-used and
7360 singly-used registers optimized away)
7362 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7364 * 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.
7366 2002-05-10 Scott Dattalo <scott AT dattalo.com>

7389 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7391 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7393 2002-03-28 Johan Knol <johan AT balder>
7395 * src/SDCCval.c: fixed bug #532436
7397 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7399 Added "char *Processor" field to the port structure.
7402 Added -p option. Allows port dependent processor to be specified.
7405 Initialized the new field char *Processor field to NULL in all ports
7408 Compiler generated registers for interrupt context saving
7409 were not getting allocated.
7411 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7414 Fixed left shift. Will promote the left side of a left shift
7415 if a) left shifting more than size of operand or b) when assigned
7416 to something size > size of left side
7418 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7420 tons of changes. Register allocation has been
7421 rewritten. Added customization for the various PICs. Flow
7422 analysis is restructured. ...
7428 Added. device.c is a PIC port hack to accomodate variations
7431 2002-03-13 Michael Hope <michaelh AT vroom>
7433 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7435 2002-03-04 johanknol <johanknol AT manik>
7437 * /src/SDCCval.c: fixed
7439 const unsigned char arr[][2] = { { 0, 1 } };
7440 t18.c:1: error: Initializer element is not constant
7442 2002-03-04 bela <bela AT manik>
7444 * /device/include/mcs51reg.h:
