10 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
11 on rIfx (genCmp was broken)
13 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
15 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
16 * src/z80/main.c (_keywords[]),
17 * src/SDCCglobal.h (struct options),
19 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
20 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
21 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
22 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
23 always available in leading double underscore form. The C99 support is
24 mostly missing, but it's a start.
25 * support/regression/tests/bug-227710.c: fixed nonconforming use of
26 reserved identifier "__data".
28 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

72 immedDom() returning wrong block; probably fixes bug #1160833)
74 2005-03-20 Borut Razem <borut.razem AT siol.net>

104 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
106 * device/lib/printf_large.c: removed inline assembly for portability and
107 readability. Use printf_fast if speed or size are more important.
108 * src/pic16/gen.c: removed conditions around use of DEBUGpc
109 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
111 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
113 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
114 prevent compiler warning
116 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
118 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
119 moved to level 0 and declared as static. Also they are explicit
120 placed in access bank. This was necessery because some times they
121 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
122 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
123 optimizations. Currently only compare to unsigned char is implemented,
124 * src/pic16/gen.c: added fReturnIdx array,
125 * (struct resolvedIfx) is moved to gen.h and made public,
126 * (struct _G): added sregsAlloc and sregsAllocSet fields,
127 * (aopForSym): added an optimization to directly store in stack of
128 the operand of a SEND iCode,
129 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
130 but as registers instead (AOP_REG) using the fReturnIdx array,
131 * (pic16_freeAsmop): remove the freed register from the
133 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
135 * (pic16_popGetTempRegCond): changed function prototype, now
136 function takes also a bitVector argument v which holds the current
137 set of registers that are allocated for stack access by aopForSym,
138 registers allocated in aopForSym for accessing stack symbols are not
139 any more part of the functions usedRegs field,
140 * (genCall): some times aopOp is called for a stack variable to be
141 send, aopForSym might perform the push, if this is true make sure
142 that genCall doesn't push the variable twice by testing _G.resDirect,
143 * (genFunction): changed testing for unspecified interrupt number
144 from 256 to INTNO_UNSPEC,
145 * modified selection scheme of frame pointer generation. Previously
146 if function did use local registers a frame pointer was generated,
147 now a frame pointer is generated only if function has arguments
148 (that need PLUSW2 register access), or has stack arguments, or the
149 compiler is not instructed to omit the frame pointer,
150 * (genEndFunction): before restoring local registers that were saved
151 in the function preamble, also restore the registers that *might*
152 have been allocated for stack access,
153 * (genRet): removed some old comments,
154 * (genCmp, the active (RN's) version): added a call to the
155 pic16_genCmp_special function to perform the compare with a more
156 robust and optimized way,
157 * (genInline): a feature has been added in inline code generation,
158 which allows a wildcard variable substitution when writing inline
159 assembly. Code is incomplete and experimental therefore undocumented,
160 * (genCast): changed order of aopOp for result and right to allow
161 aopForSym to directly load the result if possible,
162 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
163 perform an optimized compare on some selected special occasions,
164 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
165 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
166 generate an IVT any more,
167 * src/pic16/main.c (pic16_optionsTable): added command line option
169 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
170 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
172 * src/pic16/NOTES: Raphael Neider added in list of active developers
173 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
174 jumptable_end to prevent bug #,
175 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
176 inCond and outCond fields,
177 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
178 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
179 turn off register spilling,
180 * (packRegsForOneUse): synced with other ports' versions although it
181 is not used currently,
182 * (pic16_packRegisters): added an optimization while reading
183 structure bitfields, some registers may be saved (malloc code is
184 decreased by 80 bytes)
186 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
188 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
189 left is a bitfield, if yes, then don't optimize assignment. Perhaps
190 this can be optimized more?
192 2005-03-10 Raphael Neider <rneider AT web.de>
194 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
195 genNearPointerGet): (hopefully) fixed access to bitfields via
196 pointers (p->bitN = x; and x = p->bitN; failed)

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

869 functions, ctype functions and macros and some functions of the
870 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
871 be extensively tested in the future. Standard disclaimer here.

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

3914 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3916 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3917 loaded with the linker search paths (-L arguments) and the libraries
3918 to be linked with the current source (-l arguments). Changes
3919 currently will affect only the pic16 port.
3920 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3921 include path the port specific paths and port specific libraries,
3922 * gplink command now contains the $3 argument,
3923 * src/pic16/device.h,
3924 * src/pic16/device.c,: structure PIC_device is made public and
3925 renamed to PIC16_device, the same for variable Pics which is renamed

3940 Documenting changes from previous commits.
3941 * configure.in (version 1.56),
3942 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3943 when generating output files to configure the pic16 library,
3944 but now I've commented it out, since gputils aren't installed in the
3945 SF compile farm, so library won't compile
3947 * device/lib/Makefile.in (version 1.56): initially I've added in
3948 target 'all' the prerequestive 'model-pic16' so it compiled the
3949 pic16 library, but now I've commented it out for the same reasons
3951 * added targets 'model-pic16' and 'objects-pic16' to compile the
3953 * added target 'port-specific-objects-pic16' to handle the
3954 generated libraries and copy them into the build/ directory
3955 * added target 'clean-intermediate-pic16' to clean intermediate
3956 files into pic16 directory
3957 * in target 'installdirs' added line to create directory pic16 in
3958 the installation path

3961 added lines to copy all header files to installation path,
3962 * in target 'installdirs' added line create directory for pic16
3963 headers in the installation path

3979 option so that it actually works. Made it specific to the z80, since
3980 the gbz80 doesn't have these kinds of I/O ports.
3982 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3984 * device/include/z180.h,

4008 via literal number. The symbol is placed in the corresponding
4009 position of the data ram
4010 * (pic16_dump_section): relocatable and absolute uninitialized
4011 data are now emitted in sorted order to reduce section naming,
4012 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
4013 weren't marked as being in the access bank,
4015 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
4017 Added portion of GNU PIC Library under the directory
4018 device/include/pic16 and device/lib/pic16. These files
4019 contain the declarations of SFRs for the PIC18Fxx2 devices.
4020 The directory is initialized via configure from toplevel.

4031 2004-01-12 Borut Razem <borut.razem AT siol.net>
4033 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
4034 doc/sdccman.lyx: upper case pragmas are deprecated
4036 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>

4049 * doc/sdccman.lyx: Moved and added some sections, small changes
4050 all over. Telling LaTeX to be less strict with word spacing
4051 to better keep the right margin. Changed some notes about
4052 maintainance of the ports in section 3.2.1 - is it OK like this?
4054 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
4056 SDCC source changes:
4057 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

4063 processor registers declared internally by the port are emitted in
4064 the translation as equates,
4065 * src/pic16/gen.c: inline code is passed unprocessed to the

4091 UPPER for immediate operands,
4092 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4094 * src/pic16/peeph.def: all peepholes with movff are commented out,
4095 because there is a problem in the pcode peep optimizer,
4096 * src/pic16/ralloc.c: the register allocator can now reuse local

4189 include information about variables allocated to the overlay
4192 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4194 * as/mcs51/lkmain.c: Help about -Y option

4206 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4208 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4209 (default behaviour).
4211 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4213 A python script to validate compiler diagnostic messages. It can be
4214 used to verify that sdcc complains about bad c source code and
4215 gives a good location of the error.
4216 * support/valdiag/Makefile,
4217 * support/valdiag/valdiag.py,
4218 * support/valdiag/tests/*
4220 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4233 * src/common.h: added ifndef/define/endif macros
4234 around the header file.
4235 Bug reported from Jesus Calvino-Fraga
4237 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4239 * sdcc.spec: updated
4240 * device/include/Makefile.in: don't install CVS directories
4241 * device/lib/Makefile.in: added removal of CVS directories after install
4242 * doc/Makefile: fixed install, added local_icons
4243 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4244 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4245 * src/ds390/gen.c (genRightShift): fixed bug #870788
4246 * src/SDCCast.c (decorateType): fixed bug #870781
4248 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4250 PIC16 port related changes:
4251 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4252 added variable stackPos,
4254 * gen.c: genCall, assignResultValue: added support for
4255 pushing/retrieving function parameters to/from stack,
4256 genFunction,genEndFunction: setup stack frame for the
4258 genAddrOf: will be changed according to bug 863624
4260 * added files genutils.c and genutils.h which contain gen*
4261 debugged and optimised functions extracted from gen.c
4263 * glue.c: added variable 'externs' which holds extern symbols,
4264 pic16emitRegularMap: is modified to properly handle relocatable
4265 symbols under the new scheme,
4266 pic16createInterruptVect: is modified
4267 pic16printPublics: is modified to emit 'global' assembler directives,
4268 added pic16_printExterns to print extern symbols,
4269 pic16glue: initializes stack/frame pointer in the beginning of
4270 the assembly output. Temporary hack, will be corrected later,
4271 because gplink yet does not support stack and SDCC does not
4272 yet support a type of crt0.o object to create the final binary.
4274 * Removed many lines that contain 8051 legacy code.
4275 * The code is finally placed under a 'code' directive.
4276 * Added port specific options.
4278 * _process_pragma: simplified since now we do not need *special*
4279 include file to define SFR registers. But a separate header
4280 will be needed. This will be developed later.
4281 * _pic16_parseOptions: added, parses port specific options:
4282 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4283 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4284 --preplace-udata-with=
4286 * _pic16_setDefaultOptions: modified to initialize section names,
4287 but hack is temporarly out of order since it needs improvement.
4288 * _pic16_genAssemblerPreamble: configuration words are emitted by
4289 their address instead of their name. This part is incomplete and
4290 supports only the 18Fxx2 devices. Other devices will emit an error
4291 during assembly since they do not contain the same set of config
4293 * _pic16_genIVT: is modified,
4295 * pcode.c: added definitions for some hardware registers that are needed
4297 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4298 All PCI entries are updated. Now LFSR is supported.
4299 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4300 * added pic16_newpCodeOpLit2 to support instructions with
4301 two literal arguments
4302 * pic16_pCode2str: corrected code that emits assembler instructions
4303 with two literal operands and those that have an access bit modifier
4304 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4305 this fixes a bug which caused some labels to be lost, when an
4306 assembler directive was added, i.e. banksel,
4307 * pic16_FixRegisterBanking: improved logic that causes the insertion
4309 * InlineFunction: functions that are called once, are not any more
4310 inlined. This can be a port option in the future,
4312 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4314 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4315 hold the corresponding uninitialized symbols,
4316 * pic16_allocProcessorRegister: registers have explicit marked the
4318 * pic16_allocInternalRegister: registers are explicit marked as
4320 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4321 processing list, so bit registers were lost,
4324 * ralloc.h: added field 'accessBank' and original symbol operand
4325 in register definition,
4326 * removed the field isMapped from register definition,
4328 ** Several functions have been removed from various sources:
4329 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4330 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4331 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4332 pic16_assignRelocatableRegisters
4334 ** others have been introduced:
4335 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4336 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4338 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4340 * support/scripts/inc2h.pl: changed definition of BIT_AT
4341 to emit 'sbit at' instead of 'bit at'. This was a request.
4343 PIC16 port related preliminary changes:
4344 * gen.c: prefixed function popRegFromString with
4345 pic16_ and all references to it corrected
4346 * pcode.c: all pic16_pc_* hardware registers prefixed
4347 with underscore (_),
4348 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4349 * ralloc.c: newReg(): when register is REG_SFR then
4350 set address to rIdx,
4351 pic16_allocProcessorRegister(): marks register wasUsed=0
4352 pic16_writeUsedRegs(): added a call to assign processor
4353 registers via pic16_assignFixedRegisters
4355 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4357 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4358 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4359 variables in unused register banks. Also the SSEG is placed
4360 wherever there is enough space for it, and IDATA can be anywhere
4361 in internal RAM. For now compile using -Wl-Y[stack_size].
4362 The mem file is different for this option as well, since it
4363 makes no sense of talking about DSEG lenght.
4365 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4367 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4368 in certain cases, e.g. when ROM assignment, patch provided
4369 from Albert den Haan.
4371 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4514 * src/mcs51/peephole.def,
4515 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
4516 (allows non-interrupt and interrupt code to safely compete for a resource

5394 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5395 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5396 type for bits was changed. It resulted in bit variables becoming

5414 A few small changes that speed up the peephole optimizer.
5418 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5420 Try to make the peephole optimizer smarter by maintaining
5421 an association between the assembly source code and the
5422 iCodes that originated them. Put this information to use
5423 with a new peephole rule condition "notVolatile" so that
5424 the rules can be aggressive yet still safe.
5429 * src/mcs51/peeph.def
5431 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5435 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5436 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5437 if the left or right operand symbols have the accuse flag set.
5439 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5441 Changed the type of the result of the ! (NOT) operator to char;
5442 previously it returned the same type as the source. This allows
5443 us to eliminate all the genFloatNot functions (all of its target
5444 implementations were very buggy) since !float can use the same
5447 * src/SDCCicode.c (ast2iCode): ! returns char

5456 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5457 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5458 during interrupts. Ensure WSAVE is located at a shared bank address.
5459 2. Fixed page selection in some places
5460 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5461 the registers name strings.
5462 4. Fixed "signed / unsigned compare" compiler warnings.
5463 5. The PIC port manages its own allocation of the general purpose
5464 registers, but makes no attempt to reuse them. As a result when
5465 compiling it soon runs out of general purpose registers. Some
5466 additional code was added to the files pcode.c and device.c to walk
5467 through the function call tree and rename the registers so that they
5477 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5478 genPlus() & genMinus() when the result is the same as left or right

5484 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5486 Made bitfield a distinct type from bit so that bitfields
5487 convert as per ANSI C and bits retain their traditional
5488 boolean style behaviour. Implemented bitfield support in
5496 * src/ds390/gen.c: bit v bitfield split
5497 * src/z80/gen.c: New support for bitfields
5498 * support/regression/tests/bitfields.c: reenabled z80,
5501 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5503 Rules 246.x, 247.x relate to bitfields, the others speed up
5504 access to xdata mapped I/O devices.
5506 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5508 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5510 Cleaned up genPackBits and genUnpackBits and added two helper

5520 Fixed bug #748310 (pointer to function type mishandled when the
5521 function name is omitted). Also fixed a SIGSEGV when a function
5522 attribute (reentrant, etc) is used on a non-function or on a
5523 function but misplaced before the parameter list.

5552 Made the constant following the "interrupt" keyword optional. If
5553 omitted, the function will not automatically be given an entry
5554 in the interrupt vector table (similar to #pragma NOIV, but
5555 less syntacticly kludgy). The interrupt number is also now
5556 range checked. Also fixed a bug in the high order bit example
5563 * support/Util/SDCCerr.c
5564 * support/Util/SDCCerr.h
5567 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

5577 unsigned, but are signed by default
5578 * src/SDCCval.c (constVal): rearranged
5579 * src/SDCCval.c (valMod): preliminary fix
5580 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5624 * src/SDCCval.c (valDiv, valMod): fixed signdness
5625 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5626 signedness of modulo, left and right shift

6089 the compiler with no port specified on command line, a default
6090 port is selected with the new macro DEFAULT_PORT which is
6091 defined in port.h, in setDefaultOptions() linkOptions is removed
6092 from initialization assignment, since now it is a set,
6093 parseCmdLine uses setParseWithComma for linkOptions, in
6094 linkEdit() linkOptions are accessed with new function indexSet()
6095 which returns the i'th item of a set variable. See SDCCset.c, in

7162 2003-01-04 <johan AT balder>
7164 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7166 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7167 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7169 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7170 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

7177 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7179 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7180 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7182 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7184 * in \sdcc\as\mcs51\ changed these files in order to create an
7185 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7186 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7187 following files to include the previous two files: aslink.dsp,
7188 Makefile.aslink, Makefile.bcc, and Makefile.in.
7190 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7191 .adb instead of .cdb
7193 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7195 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7196 value from option --iram-size.
7198 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7200 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7203 2002-09-18 <wiml AT hhhh.org>
7205 * SDCClrange.h: exposed setFromRange() and setToRange()
7206 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7207 packRegsForAccUse() (bug 542397)
7208 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7209 multiple times and emitting the fetch operations more than once
7210 added aopGetUsesAcc() function to allow binary operators to
7211 fetch their operands in the correct order; made genMinus() emit
7212 compact code for X = LITERAL - Y
7214 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7215 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7216 sprintf() in line 1267.
7218 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7219 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7222 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7223 Changes to aslink (All the changes are marked with 'JCF'):
7225 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7228 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7229 area BSEG. Also moves, if possible, the DATA area down into the internal
7230 ram so more space is available.
7232 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7235 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7236 not bytes. Function summary() which creates a memory usage summary
7237 file with extension .mem. Reports of overlaping stack and small stack
7238 size. If the space for the stack is less than 16 bytes aslink trows a
7241 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7242 the 8051. Option 'y' for memory summary output file.
7244 Changes to sdcc (All the changes are marked with 'JCF'):
7246 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7248 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7249 overlaying area for it (uses RegBankUsed[4]).
7251 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7252 bank zero as used by default. By default aslink locates the stack
7253 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7254 the creation of the .mem file. Delegates the allocation of data area
7255 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7256 the begining of the stack area to aslink.
7258 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7259 glue() in SDCCglue.c creates an area for it.
7261 2002-09-03 Borut Razem <borut.razem AT siol.net>
7262 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7263 sdcc/src/pic/glue.c:
7264 introduced atexit() handler for teporay files removal in case of
7265 errors, assertions, ...
7267 2002-08-29 Borut Razem <borut.razem AT siol.net>
7268 * sdcc/support/cpp2/auto-host_vc_in.h:
7269 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7270 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7271 Maybe there is a similar problem with BORLANDC? It should be checked!
7273 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7274 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7275 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7276 was not executed, and the compiler (cl) launched a warning:
7277 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7279 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7280 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7282 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7283 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7285 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7286 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7287 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7288 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7289 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7290 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7291 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7292 - added Release configuration in VS projects
7293 - review of compiler an linker options
7294 - VC .exe files are generated in bin_vc directory, not to interfere
7295 with binaries generated from other projects (cygwin, mingw, bcc ...)
7297 * sdcc/src/yacc.dsp: added
7299 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7300 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7301 and insert the version number definitions from .version
7303 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7305 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7306 added - genarate auto-host.h using auto-host_vc_in.h as template
7309 removed from CVS, generated automatically
7311 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7312 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7314 2002-08-11 Borut Razem <borut.razem AT siol.net>
7315 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7317 2002-08-10 Borut Razem <borut.razem AT siol.net>
7318 * src/SDCCmain.c (main):
7319 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7320 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7321 The consequence was that some temporary files were not removed.
7324 unification of code in functions tempfilename() and tempfile():
7325 function tempnam() is defined in Visual Studio 6.0 and .NET
7327 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7329 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7330 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7331 - removed compiler command line option /WX: Treats all warnings as errors
7332 - update a list of source files, included into the project
7334 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7335 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7336 changed project type to Generic Project so that can be correcly converted to VS.NET project
7338 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7340 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7342 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7344 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7345 added return 0 statements after assert() to make compiler happy
7347 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7348 added newline in the def file to keep MSC compiler satisfied
7350 * sdcc/src/z80/gen.c:
7351 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7352 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7353 - solved MSC error in function aopDump()
7355 * sdcc_vc.h: define PREFIX as "\\sdcc"
7357 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7358 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7360 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7361 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7362 - Rewrote the register banking algorithm.
7363 - Added pCode live-range analysis to registers (for now, only non-used and
7364 singly-used registers optimized away)
7366 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7368 * 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.
7370 2002-05-10 Scott Dattalo <scott AT dattalo.com>

7389 * src/z80/peeph.def: Added transpose redundent load rule.
7391 * src/z80/main.c: Added force callee saves for jaune.
7393 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7395 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7397 2002-03-28 Johan Knol <johan AT balder>
7399 * src/SDCCval.c: fixed bug #532436
7401 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7403 Added "char *Processor" field to the port structure.
7406 Added -p option. Allows port dependent processor to be specified.
7409 Initialized the new field char *Processor field to NULL in all ports
7412 Compiler generated registers for interrupt context saving
7413 were not getting allocated.
7415 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7418 Fixed left shift. Will promote the left side of a left shift
7419 if a) left shifting more than size of operand or b) when assigned
7420 to something size > size of left side
7422 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7424 tons of changes. Register allocation has been
7425 rewritten. Added customization for the various PICs. Flow
7426 analysis is restructured. ...
7432 Added. device.c is a PIC port hack to accomodate variations
7435 2002-03-13 Michael Hope <michaelh AT vroom>
7437 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7439 2002-03-04 johanknol <johanknol AT manik>
7441 * /src/SDCCval.c: fixed
7443 const unsigned char arr[][2] = { { 0, 1 } };
7444 t18.c:1: error: Initializer element is not constant
7446 2002-03-04 bela <bela AT manik>
7448 * /device/include/mcs51reg.h:
