36 * src/SDCCcflow.c (*),
38 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
39 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
40 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
41 immedDom() returning wrong block; probably fixes bug #1160833)
43 2005-03-20 Borut Razem <borut.razem AT siol.net>
45 * support/scripts/inc2h.pl: WIN32 port

68 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
70 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
71 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
73 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
75 * device/lib/printf_large.c: removed inline assembly for portability and
76 readability. Use printf_fast if speed or size are more important.
77 * src/pic16/gen.c: removed conditions around use of DEBUGpc
78 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
80 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
82 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
83 prevent compiler warning
85 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
87 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
88 moved to level 0 and declared as static. Also they are explicit
89 placed in access bank. This was necessery because some times they
90 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
91 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
92 optimizations. Currently only compare to unsigned char is implemented,
93 * src/pic16/gen.c: added fReturnIdx array,
94 * (struct resolvedIfx) is moved to gen.h and made public,
95 * (struct _G): added sregsAlloc and sregsAllocSet fields,
96 * (aopForSym): added an optimization to directly store in stack of
97 the operand of a SEND iCode,
98 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
99 but as registers instead (AOP_REG) using the fReturnIdx array,
100 * (pic16_freeAsmop): remove the freed register from the
102 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
104 * (pic16_popGetTempRegCond): changed function prototype, now
105 function takes also a bitVector argument v which holds the current
106 set of registers that are allocated for stack access by aopForSym,
107 registers allocated in aopForSym for accessing stack symbols are not
108 any more part of the functions usedRegs field,
109 * (genCall): some times aopOp is called for a stack variable to be
110 send, aopForSym might perform the push, if this is true make sure
111 that genCall doesn't push the variable twice by testing _G.resDirect,
112 * (genFunction): changed testing for unspecified interrupt number
113 from 256 to INTNO_UNSPEC,
114 * modified selection scheme of frame pointer generation. Previously
115 if function did use local registers a frame pointer was generated,
116 now a frame pointer is generated only if function has arguments
117 (that need PLUSW2 register access), or has stack arguments, or the
118 compiler is not instructed to omit the frame pointer,
119 * (genEndFunction): before restoring local registers that were saved
120 in the function preamble, also restore the registers that *might*
121 have been allocated for stack access,
122 * (genRet): removed some old comments,
123 * (genCmp, the active (RN's) version): added a call to the
124 pic16_genCmp_special function to perform the compare with a more
125 robust and optimized way,
126 * (genInline): a feature has been added in inline code generation,
127 which allows a wildcard variable substitution when writing inline
128 assembly. Code is incomplete and experimental therefore undocumented,
129 * (genCast): changed order of aopOp for result and right to allow
130 aopForSym to directly load the result if possible,
131 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
132 perform an optimized compare on some selected special occasions,
133 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
134 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
135 generate an IVT any more,
136 * src/pic16/main.c (pic16_optionsTable): added command line option
138 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
139 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
141 * src/pic16/NOTES: Raphael Neider added in list of active developers
142 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
143 jumptable_end to prevent bug #,
144 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
145 inCond and outCond fields,
146 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
147 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
148 turn off register spilling,
149 * (packRegsForOneUse): synced with other ports' versions although it
150 is not used currently,
151 * (pic16_packRegisters): added an optimization while reading
152 structure bitfields, some registers may be saved (malloc code is
153 decreased by 80 bytes)
155 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
157 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
158 left is a bitfield, if yes, then don't optimize assignment. Perhaps
159 this can be optimized more?
161 2005-03-10 Raphael Neider <rneider AT web.de>
163 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
164 genNearPointerGet): (hopefully) fixed access to bitfields via
165 pointers (p->bitN = x; and x = p->bitN; failed)

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

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

3885 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3886 loaded with the linker search paths (-L arguments) and the libraries
3887 to be linked with the current source (-l arguments). Changes
3888 currently will affect only the pic16 port.
3889 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3890 include path the port specific paths and port specific libraries,
3891 * gplink command now contains the $3 argument,
3892 * src/pic16/device.h,
3893 * src/pic16/device.c,: structure PIC_device is made public and

3909 Documenting changes from previous commits.
3910 * configure.in (version 1.56),
3911 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3912 when generating output files to configure the pic16 library,
3913 but now I've commented it out, since gputils aren't installed in the
3914 SF compile farm, so library won't compile
3916 * device/lib/Makefile.in (version 1.56): initially I've added in
3917 target 'all' the prerequestive 'model-pic16' so it compiled the
3918 pic16 library, but now I've commented it out for the same reasons
3920 * added targets 'model-pic16' and 'objects-pic16' to compile the
3922 * added target 'port-specific-objects-pic16' to handle the
3923 generated libraries and copy them into the build/ directory
3924 * added target 'clean-intermediate-pic16' to clean intermediate
3925 files into pic16 directory
3926 * in target 'installdirs' added line to create directory pic16 in

3930 added lines to copy all header files to installation path,
3931 * in target 'installdirs' added line create directory for pic16
3932 headers in the installation path

3948 option so that it actually works. Made it specific to the z80, since
3949 the gbz80 doesn't have these kinds of I/O ports.
3951 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4060 UPPER for immediate operands,
4061 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4063 * src/pic16/peeph.def: all peepholes with movff are commented out,
4064 because there is a problem in the pcode peep optimizer,
4065 * src/pic16/ralloc.c: the register allocator can now reuse local
4066 function symbols for another function. This saves register usage.
4067 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4069 Added file src/pic16/NOTES with information about program writing on

4175 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4177 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4178 (default behaviour).
4180 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4182 A python script to validate compiler diagnostic messages. It can be
4183 used to verify that sdcc complains about bad c source code and
4184 gives a good location of the error.
4185 * support/valdiag/Makefile,
4186 * support/valdiag/valdiag.py,

4206 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4208 * sdcc.spec: updated
4209 * device/include/Makefile.in: don't install CVS directories
4210 * device/lib/Makefile.in: added removal of CVS directories after install
4211 * doc/Makefile: fixed install, added local_icons
4212 * sim/ucsim/gui.src/Makefile.in: fixed an old typo

4217 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4219 PIC16 port related changes:
4220 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4221 added variable stackPos,
4223 * gen.c: genCall, assignResultValue: added support for
4224 pushing/retrieving function parameters to/from stack,
4225 genFunction,genEndFunction: setup stack frame for the
4227 genAddrOf: will be changed according to bug 863624
4229 * added files genutils.c and genutils.h which contain gen*
4230 debugged and optimised functions extracted from gen.c
4232 * glue.c: added variable 'externs' which holds extern symbols,
4233 pic16emitRegularMap: is modified to properly handle relocatable
4234 symbols under the new scheme,
4235 pic16createInterruptVect: is modified
4236 pic16printPublics: is modified to emit 'global' assembler directives,
4237 added pic16_printExterns to print extern symbols,
4238 pic16glue: initializes stack/frame pointer in the beginning of
4239 the assembly output. Temporary hack, will be corrected later,
4240 because gplink yet does not support stack and SDCC does not
4241 yet support a type of crt0.o object to create the final binary.
4243 * Removed many lines that contain 8051 legacy code.
4244 * The code is finally placed under a 'code' directive.
4245 * Added port specific options.
4247 * _process_pragma: simplified since now we do not need *special*
4248 include file to define SFR registers. But a separate header
4249 will be needed. This will be developed later.
4250 * _pic16_parseOptions: added, parses port specific options:
4251 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4252 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4253 --preplace-udata-with=
4255 * _pic16_setDefaultOptions: modified to initialize section names,
4256 but hack is temporarly out of order since it needs improvement.
4257 * _pic16_genAssemblerPreamble: configuration words are emitted by
4258 their address instead of their name. This part is incomplete and
4259 supports only the 18Fxx2 devices. Other devices will emit an error
4260 during assembly since they do not contain the same set of config
4262 * _pic16_genIVT: is modified,
4264 * pcode.c: added definitions for some hardware registers that are needed
4266 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4267 All PCI entries are updated. Now LFSR is supported.
4268 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4269 * added pic16_newpCodeOpLit2 to support instructions with
4270 two literal arguments
4271 * pic16_pCode2str: corrected code that emits assembler instructions
4272 with two literal operands and those that have an access bit modifier
4273 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4274 this fixes a bug which caused some labels to be lost, when an
4275 assembler directive was added, i.e. banksel,
4276 * pic16_FixRegisterBanking: improved logic that causes the insertion
4278 * InlineFunction: functions that are called once, are not any more
4279 inlined. This can be a port option in the future,
4281 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4283 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4284 hold the corresponding uninitialized symbols,
4285 * pic16_allocProcessorRegister: registers have explicit marked the
4287 * pic16_allocInternalRegister: registers are explicit marked as
4289 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4290 processing list, so bit registers were lost,
4293 * ralloc.h: added field 'accessBank' and original symbol operand
4294 in register definition,
4295 * removed the field isMapped from register definition,
4297 ** Several functions have been removed from various sources:
4298 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4299 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4300 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4301 pic16_assignRelocatableRegisters
4303 ** others have been introduced:
4304 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4305 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4307 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4309 * support/scripts/inc2h.pl: changed definition of BIT_AT
4310 to emit 'sbit at' instead of 'bit at'. This was a request.
4312 PIC16 port related preliminary changes:
4313 * gen.c: prefixed function popRegFromString with
4314 pic16_ and all references to it corrected
4315 * pcode.c: all pic16_pc_* hardware registers prefixed
4316 with underscore (_),
4317 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4318 * ralloc.c: newReg(): when register is REG_SFR then
4319 set address to rIdx,
4320 pic16_allocProcessorRegister(): marks register wasUsed=0
4321 pic16_writeUsedRegs(): added a call to assign processor
4322 registers via pic16_assignFixedRegisters
4324 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4326 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4327 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4328 variables in unused register banks. Also the SSEG is placed
4329 wherever there is enough space for it, and IDATA can be anywhere
4330 in internal RAM. For now compile using -Wl-Y[stack_size].
4331 The mem file is different for this option as well, since it
4332 makes no sense of talking about DSEG lenght.
4334 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4336 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4337 in certain cases, e.g. when ROM assignment, patch provided
4338 from Albert den Haan.
4340 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4483 * src/mcs51/peephole.def,
4484 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

5225 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
5226 support for standard C idiom of memory mapped variables; for
5227 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5228 to xdata int at 0x1234 tempvar = 1.
5229 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5230 provided by Akiya ISHIDA

5246 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5248 Fixed bug #621531 (const & volatile confusion in the type chain).
5249 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

5341 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5342 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5343 fetching of the pointer
5344 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5345 copied from genNearPointerSet()
5346 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5347 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5348 If they pop r0/r1 they must be called in the opposite order than aopOp().

5361 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5363 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5364 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5365 type for bits was changed. It resulted in bit variables becoming
5366 global, which is not permitted in PIC 14 assembly output.
5368 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5383 A few small changes that speed up the peephole optimizer.
5387 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5389 Try to make the peephole optimizer smarter by maintaining
5390 an association between the assembly source code and the
5391 iCodes that originated them. Put this information to use
5392 with a new peephole rule condition "notVolatile" so that
5393 the rules can be aggressive yet still safe.
5398 * src/mcs51/peeph.def
5400 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5404 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5405 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5406 if the left or right operand symbols have the accuse flag set.
5408 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5410 Changed the type of the result of the ! (NOT) operator to char;
5411 previously it returned the same type as the source. This allows
5412 us to eliminate all the genFloatNot functions (all of its target
5413 implementations were very buggy) since !float can use the same
5416 * src/SDCCicode.c (ast2iCode): ! returns char

5425 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5426 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5427 during interrupts. Ensure WSAVE is located at a shared bank address.
5428 2. Fixed page selection in some places
5429 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5430 the registers name strings.
5431 4. Fixed "signed / unsigned compare" compiler warnings.
5432 5. The PIC port manages its own allocation of the general purpose
5433 registers, but makes no attempt to reuse them. As a result when
5434 compiling it soon runs out of general purpose registers. Some
5435 additional code was added to the files pcode.c and device.c to walk
5436 through the function call tree and rename the registers so that they
5446 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5447 genPlus() & genMinus() when the result is the same as left or right

5453 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5455 Made bitfield a distinct type from bit so that bitfields
5456 convert as per ANSI C and bits retain their traditional
5457 boolean style behaviour. Implemented bitfield support in
5465 * src/ds390/gen.c: bit v bitfield split
5466 * src/z80/gen.c: New support for bitfields
5467 * support/regression/tests/bitfields.c: reenabled z80,
5470 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5472 Rules 246.x, 247.x relate to bitfields, the others speed up
5473 access to xdata mapped I/O devices.
5475 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5477 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5479 Cleaned up genPackBits and genUnpackBits and added two helper
5480 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5481 for literal assignments in genPackBits (thanks to Frieder for
5487 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5489 Fixed bug #748310 (pointer to function type mishandled when the
5490 function name is omitted). Also fixed a SIGSEGV when a function
5491 attribute (reentrant, etc) is used on a non-function or on a
5492 function but misplaced before the parameter list.
5494 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5496 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5497 * support/Util/SDCCerr.h,

5519 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5521 Made the constant following the "interrupt" keyword optional. If
5522 omitted, the function will not automatically be given an entry
5523 in the interrupt vector table (similar to #pragma NOIV, but
5524 less syntacticly kludgy). The interrupt number is also now
5525 range checked. Also fixed a bug in the high order bit example

5539 * src/SDCCicode.c (operandOperation): rewritten some ops
5540 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5541 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5543 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can

6055 added if/endif conditional macros to remove options help
6056 messages from optionsTable when a port is not configured, added
6057 support for the PIc16 port in the ports table, when executing
6058 the compiler with no port specified on command line, a default
6059 port is selected with the new macro DEFAULT_PORT which is
6060 defined in port.h, in setDefaultOptions() linkOptions is removed
6061 from initialization assignment, since now it is a set,
6062 parseCmdLine uses setParseWithComma for linkOptions, in
6063 linkEdit() linkOptions are accessed with new function indexSet()
6064 which returns the i'th item of a set variable. See SDCCset.c, in
6065 linkEdit() when calling buildCmdLine(), added linkOptions as
6066 last argument. Now users can pass arguments to gplink via the
6067 -Wl option, main() uses pic16glue() to glue up pic16 programs

6081 gpasm complaining and test the linkage with gplink, _linkCmd and
6082 _asmCmd changed to be more gplink and gpasm friendly
6083 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6084 produced an error when parsed, peep rule 12 is added to utilize
6085 movff, but it is commented out since the pCode does not support
6086 yet a command with 2 address arguments
6088 2003-05-18 <johan AT balder>
6090 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7129 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7131 2003-01-04 <johan AT balder>
7133 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7135 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

7148 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7149 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7151 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7153 * in \sdcc\as\mcs51\ changed these files in order to create an
7154 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7155 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7156 following files to include the previous two files: aslink.dsp,
7157 Makefile.aslink, Makefile.bcc, and Makefile.in.
7159 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7160 .adb instead of .cdb
7162 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7164 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7165 value from option --iram-size.
7167 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7169 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7172 2002-09-18 <wiml AT hhhh.org>
7174 * SDCClrange.h: exposed setFromRange() and setToRange()
7175 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7176 packRegsForAccUse() (bug 542397)
7177 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7178 multiple times and emitting the fetch operations more than once
7179 added aopGetUsesAcc() function to allow binary operators to
7180 fetch their operands in the correct order; made genMinus() emit
7181 compact code for X = LITERAL - Y
7183 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7184 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7185 sprintf() in line 1267.
7187 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7188 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7191 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7192 Changes to aslink (All the changes are marked with 'JCF'):
7194 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7197 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7198 area BSEG. Also moves, if possible, the DATA area down into the internal
7199 ram so more space is available.
7201 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7204 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7205 not bytes. Function summary() which creates a memory usage summary
7206 file with extension .mem. Reports of overlaping stack and small stack
7207 size. If the space for the stack is less than 16 bytes aslink trows a
7210 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7211 the 8051. Option 'y' for memory summary output file.
7213 Changes to sdcc (All the changes are marked with 'JCF'):
7215 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7217 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7218 overlaying area for it (uses RegBankUsed[4]).
7220 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7221 bank zero as used by default. By default aslink locates the stack
7222 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7223 the creation of the .mem file. Delegates the allocation of data area
7224 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7225 the begining of the stack area to aslink.
7227 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7228 glue() in SDCCglue.c creates an area for it.
7230 2002-09-03 Borut Razem <borut.razem AT siol.net>
7231 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7232 sdcc/src/pic/glue.c:
7233 introduced atexit() handler for teporay files removal in case of
7234 errors, assertions, ...
7236 2002-08-29 Borut Razem <borut.razem AT siol.net>
7237 * sdcc/support/cpp2/auto-host_vc_in.h:
7238 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7239 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7240 Maybe there is a similar problem with BORLANDC? It should be checked!
7242 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7243 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7244 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7245 was not executed, and the compiler (cl) launched a warning:
7246 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7248 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7249 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7251 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7252 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7254 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7255 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7256 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7257 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7258 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7259 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7260 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7261 - added Release configuration in VS projects
7262 - review of compiler an linker options
7263 - VC .exe files are generated in bin_vc directory, not to interfere
7264 with binaries generated from other projects (cygwin, mingw, bcc ...)
7266 * sdcc/src/yacc.dsp: added
7268 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7269 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7270 and insert the version number definitions from .version
7272 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7274 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7275 added - genarate auto-host.h using auto-host_vc_in.h as template
7278 removed from CVS, generated automatically
7280 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7281 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7283 2002-08-11 Borut Razem <borut.razem AT siol.net>
7284 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7286 2002-08-10 Borut Razem <borut.razem AT siol.net>
7287 * src/SDCCmain.c (main):
7288 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7289 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7290 The consequence was that some temporary files were not removed.
7293 unification of code in functions tempfilename() and tempfile():
7294 function tempnam() is defined in Visual Studio 6.0 and .NET
7296 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7298 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7299 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7300 - removed compiler command line option /WX: Treats all warnings as errors
7301 - update a list of source files, included into the project
7303 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7304 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7305 changed project type to Generic Project so that can be correcly converted to VS.NET project
7307 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7309 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7311 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7313 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7314 added return 0 statements after assert() to make compiler happy
7316 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7317 added newline in the def file to keep MSC compiler satisfied
7319 * sdcc/src/z80/gen.c:
7320 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7321 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7322 - solved MSC error in function aopDump()
7324 * sdcc_vc.h: define PREFIX as "\\sdcc"
7326 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7327 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7329 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7330 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7331 - Rewrote the register banking algorithm.
7332 - Added pCode live-range analysis to registers (for now, only non-used and
7333 singly-used registers optimized away)
7335 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7337 * 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 2002-03-28 Johan Knol <johan AT balder>
7368 * src/SDCCval.c: fixed bug #532436
7370 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7372 Added "char *Processor" field to the port structure.
7375 Added -p option. Allows port dependent processor to be specified.
7378 Initialized the new field char *Processor field to NULL in all ports
7381 Compiler generated registers for interrupt context saving
7382 were not getting allocated.
7384 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7387 Fixed left shift. Will promote the left side of a left shift
7388 if a) left shifting more than size of operand or b) when assigned
7389 to something size > size of left side
7391 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7393 tons of changes. Register allocation has been
7394 rewritten. Added customization for the various PICs. Flow
7395 analysis is restructured. ...
7401 Added. device.c is a PIC port hack to accomodate variations
7404 2002-03-13 Michael Hope <michaelh AT vroom>
7406 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7408 2002-03-04 johanknol <johanknol AT manik>
