45 immedDom() returning wrong block; probably fixes bug #1160833)
47 2005-03-20 Borut Razem <borut.razem AT siol.net>
49 * support/scripts/inc2h.pl: WIN32 port

72 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
74 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
75 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
77 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
79 * device/lib/printf_large.c: removed inline assembly for portability and
80 readability. Use printf_fast if speed or size are more important.
81 * src/pic16/gen.c: removed conditions around use of DEBUGpc
82 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
84 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
86 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
87 prevent compiler warning
89 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
91 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
92 moved to level 0 and declared as static. Also they are explicit
93 placed in access bank. This was necessery because some times they
94 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
95 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
96 optimizations. Currently only compare to unsigned char is implemented,
97 * src/pic16/gen.c: added fReturnIdx array,
98 * (struct resolvedIfx) is moved to gen.h and made public,
99 * (struct _G): added sregsAlloc and sregsAllocSet fields,
100 * (aopForSym): added an optimization to directly store in stack of
101 the operand of a SEND iCode,
102 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
103 but as registers instead (AOP_REG) using the fReturnIdx array,
104 * (pic16_freeAsmop): remove the freed register from the
106 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
108 * (pic16_popGetTempRegCond): changed function prototype, now
109 function takes also a bitVector argument v which holds the current
110 set of registers that are allocated for stack access by aopForSym,
111 registers allocated in aopForSym for accessing stack symbols are not
112 any more part of the functions usedRegs field,
113 * (genCall): some times aopOp is called for a stack variable to be
114 send, aopForSym might perform the push, if this is true make sure
115 that genCall doesn't push the variable twice by testing _G.resDirect,
116 * (genFunction): changed testing for unspecified interrupt number
117 from 256 to INTNO_UNSPEC,
118 * modified selection scheme of frame pointer generation. Previously
119 if function did use local registers a frame pointer was generated,
120 now a frame pointer is generated only if function has arguments
121 (that need PLUSW2 register access), or has stack arguments, or the
122 compiler is not instructed to omit the frame pointer,
123 * (genEndFunction): before restoring local registers that were saved
124 in the function preamble, also restore the registers that *might*
125 have been allocated for stack access,
126 * (genRet): removed some old comments,
127 * (genCmp, the active (RN's) version): added a call to the
128 pic16_genCmp_special function to perform the compare with a more
129 robust and optimized way,
130 * (genInline): a feature has been added in inline code generation,
131 which allows a wildcard variable substitution when writing inline
132 assembly. Code is incomplete and experimental therefore undocumented,
133 * (genCast): changed order of aopOp for result and right to allow
134 aopForSym to directly load the result if possible,
135 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
136 perform an optimized compare on some selected special occasions,
137 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
138 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
139 generate an IVT any more,
140 * src/pic16/main.c (pic16_optionsTable): added command line option
142 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
143 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
145 * src/pic16/NOTES: Raphael Neider added in list of active developers
146 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
147 jumptable_end to prevent bug #,
148 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
149 inCond and outCond fields,
150 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
151 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
152 turn off register spilling,
153 * (packRegsForOneUse): synced with other ports' versions although it
154 is not used currently,
155 * (pic16_packRegisters): added an optimization while reading
156 structure bitfields, some registers may be saved (malloc code is
157 decreased by 80 bytes)
159 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
161 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
162 left is a bitfield, if yes, then don't optimize assignment. Perhaps
163 this can be optimized more?
165 2005-03-10 Raphael Neider <rneider AT web.de>
167 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
168 genNearPointerGet): (hopefully) fixed access to bitfields via
169 pointers (p->bitN = x; and x = p->bitN; failed)

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

454 operands (genAddLit expects the iCode's operands to swapped as
455 well), fixed leftover bytes (crashed for short left operands)

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

3889 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3890 loaded with the linker search paths (-L arguments) and the libraries
3891 to be linked with the current source (-l arguments). Changes
3892 currently will affect only the pic16 port.
3893 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3894 include path the port specific paths and port specific libraries,
3895 * gplink command now contains the $3 argument,
3896 * src/pic16/device.h,
3897 * src/pic16/device.c,: structure PIC_device is made public and
3898 renamed to PIC16_device, the same for variable Pics which is renamed

3913 Documenting changes from previous commits.
3914 * configure.in (version 1.56),
3915 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3916 when generating output files to configure the pic16 library,
3917 but now I've commented it out, since gputils aren't installed in the
3918 SF compile farm, so library won't compile
3920 * device/lib/Makefile.in (version 1.56): initially I've added in
3921 target 'all' the prerequestive 'model-pic16' so it compiled the
3922 pic16 library, but now I've commented it out for the same reasons
3924 * added targets 'model-pic16' and 'objects-pic16' to compile the
3926 * added target 'port-specific-objects-pic16' to handle the
3927 generated libraries and copy them into the build/ directory
3928 * added target 'clean-intermediate-pic16' to clean intermediate
3929 files into pic16 directory
3930 * in target 'installdirs' added line to create directory pic16 in
3931 the installation path

3934 added lines to copy all header files to installation path,
3935 * in target 'installdirs' added line create directory for pic16
3936 headers in the installation path

3952 option so that it actually works. Made it specific to the z80, since
3953 the gbz80 doesn't have these kinds of I/O ports.
3955 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3957 * device/include/z180.h,

3981 via literal number. The symbol is placed in the corresponding
3982 position of the data ram
3983 * (pic16_dump_section): relocatable and absolute uninitialized
3984 data are now emitted in sorted order to reduce section naming,
3985 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3986 weren't marked as being in the access bank,
3988 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
3990 Added portion of GNU PIC Library under the directory
3991 device/include/pic16 and device/lib/pic16. These files
3992 contain the declarations of SFRs for the PIC18Fxx2 devices.
3993 The directory is initialized via configure from toplevel.
3995 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

4023 all over. Telling LaTeX to be less strict with word spacing
4024 to better keep the right margin. Changed some notes about
4025 maintainance of the ports in section 3.2.1 - is it OK like this?
4027 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

4063 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
4064 UPPER for immediate operands,
4065 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4067 * src/pic16/peeph.def: all peepholes with movff are commented out,
4068 because there is a problem in the pcode peep optimizer,
4069 * src/pic16/ralloc.c: the register allocator can now reuse local
4070 function symbols for another function. This saves register usage.

4162 include information about variables allocated to the overlay
4165 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4167 * as/mcs51/lkmain.c: Help about -Y option

4179 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4181 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4182 (default behaviour).
4184 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4186 A python script to validate compiler diagnostic messages. It can be
4187 used to verify that sdcc complains about bad c source code and
4188 gives a good location of the error.
4189 * support/valdiag/Makefile,
4190 * support/valdiag/valdiag.py,
4191 * support/valdiag/tests/*

4208 Bug reported from Jesus Calvino-Fraga
4210 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4212 * sdcc.spec: updated
4213 * device/include/Makefile.in: don't install CVS directories
4214 * device/lib/Makefile.in: added removal of CVS directories after install
4215 * doc/Makefile: fixed install, added local_icons
4216 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4217 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4218 * src/ds390/gen.c (genRightShift): fixed bug #870788
4219 * src/SDCCast.c (decorateType): fixed bug #870781
4221 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4223 PIC16 port related changes:
4224 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4225 added variable stackPos,
4227 * gen.c: genCall, assignResultValue: added support for
4228 pushing/retrieving function parameters to/from stack,
4229 genFunction,genEndFunction: setup stack frame for the
4231 genAddrOf: will be changed according to bug 863624
4233 * added files genutils.c and genutils.h which contain gen*
4234 debugged and optimised functions extracted from gen.c
4236 * glue.c: added variable 'externs' which holds extern symbols,
4237 pic16emitRegularMap: is modified to properly handle relocatable
4238 symbols under the new scheme,
4239 pic16createInterruptVect: is modified
4240 pic16printPublics: is modified to emit 'global' assembler directives,
4241 added pic16_printExterns to print extern symbols,
4242 pic16glue: initializes stack/frame pointer in the beginning of
4243 the assembly output. Temporary hack, will be corrected later,
4244 because gplink yet does not support stack and SDCC does not
4245 yet support a type of crt0.o object to create the final binary.
4247 * Removed many lines that contain 8051 legacy code.
4248 * The code is finally placed under a 'code' directive.
4249 * Added port specific options.
4251 * _process_pragma: simplified since now we do not need *special*
4252 include file to define SFR registers. But a separate header
4253 will be needed. This will be developed later.
4254 * _pic16_parseOptions: added, parses port specific options:
4255 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4256 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4257 --preplace-udata-with=
4259 * _pic16_setDefaultOptions: modified to initialize section names,
4260 but hack is temporarly out of order since it needs improvement.
4261 * _pic16_genAssemblerPreamble: configuration words are emitted by
4262 their address instead of their name. This part is incomplete and
4263 supports only the 18Fxx2 devices. Other devices will emit an error
4264 during assembly since they do not contain the same set of config
4266 * _pic16_genIVT: is modified,
4268 * pcode.c: added definitions for some hardware registers that are needed
4270 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4271 All PCI entries are updated. Now LFSR is supported.
4272 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4273 * added pic16_newpCodeOpLit2 to support instructions with
4274 two literal arguments
4275 * pic16_pCode2str: corrected code that emits assembler instructions
4276 with two literal operands and those that have an access bit modifier
4277 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4278 this fixes a bug which caused some labels to be lost, when an
4279 assembler directive was added, i.e. banksel,
4280 * pic16_FixRegisterBanking: improved logic that causes the insertion
4282 * InlineFunction: functions that are called once, are not any more
4283 inlined. This can be a port option in the future,
4285 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4287 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4288 hold the corresponding uninitialized symbols,
4289 * pic16_allocProcessorRegister: registers have explicit marked the
4291 * pic16_allocInternalRegister: registers are explicit marked as
4293 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4294 processing list, so bit registers were lost,
4297 * ralloc.h: added field 'accessBank' and original symbol operand
4298 in register definition,
4299 * removed the field isMapped from register definition,
4301 ** Several functions have been removed from various sources:
4302 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4303 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4304 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4305 pic16_assignRelocatableRegisters
4307 ** others have been introduced:
4308 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4309 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4311 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4313 * support/scripts/inc2h.pl: changed definition of BIT_AT
4314 to emit 'sbit at' instead of 'bit at'. This was a request.
4316 PIC16 port related preliminary changes:
4317 * gen.c: prefixed function popRegFromString with
4318 pic16_ and all references to it corrected
4319 * pcode.c: all pic16_pc_* hardware registers prefixed
4320 with underscore (_),
4321 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4322 * ralloc.c: newReg(): when register is REG_SFR then
4323 set address to rIdx,
4324 pic16_allocProcessorRegister(): marks register wasUsed=0
4325 pic16_writeUsedRegs(): added a call to assign processor
4326 registers via pic16_assignFixedRegisters
4328 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4330 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4331 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4332 variables in unused register banks. Also the SSEG is placed
4333 wherever there is enough space for it, and IDATA can be anywhere
4334 in internal RAM. For now compile using -Wl-Y[stack_size].
4335 The mem file is different for this option as well, since it
4336 makes no sense of talking about DSEG lenght.
4338 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4340 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4341 in certain cases, e.g. when ROM assignment, patch provided
4342 from Albert den Haan.
4344 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4487 * src/mcs51/peephole.def,
4488 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
4489 (allows non-interrupt and interrupt code to safely compete for a resource

5346 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5347 fetching of the pointer
5348 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5349 copied from genNearPointerSet()
5350 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5351 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5352 If they pop r0/r1 they must be called in the opposite order than aopOp().

5367 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5368 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5369 type for bits was changed. It resulted in bit variables becoming
5370 global, which is not permitted in PIC 14 assembly output.
5372 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5387 A few small changes that speed up the peephole optimizer.
5391 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5393 Try to make the peephole optimizer smarter by maintaining
5394 an association between the assembly source code and the
5395 iCodes that originated them. Put this information to use
5396 with a new peephole rule condition "notVolatile" so that
5397 the rules can be aggressive yet still safe.
5402 * src/mcs51/peeph.def
5404 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5408 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5409 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5410 if the left or right operand symbols have the accuse flag set.
5412 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5414 Changed the type of the result of the ! (NOT) operator to char;
5415 previously it returned the same type as the source. This allows
5416 us to eliminate all the genFloatNot functions (all of its target
5417 implementations were very buggy) since !float can use the same

5429 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5430 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5431 during interrupts. Ensure WSAVE is located at a shared bank address.
5432 2. Fixed page selection in some places
5433 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5434 the registers name strings.
5435 4. Fixed "signed / unsigned compare" compiler warnings.
5436 5. The PIC port manages its own allocation of the general purpose
5437 registers, but makes no attempt to reuse them. As a result when
5438 compiling it soon runs out of general purpose registers. Some
5439 additional code was added to the files pcode.c and device.c to walk
5440 through the function call tree and rename the registers so that they
5450 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

5457 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5459 Made bitfield a distinct type from bit so that bitfields
5460 convert as per ANSI C and bits retain their traditional
5461 boolean style behaviour. Implemented bitfield support in
5469 * src/ds390/gen.c: bit v bitfield split
5470 * src/z80/gen.c: New support for bitfields
5471 * support/regression/tests/bitfields.c: reenabled z80,
5474 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5476 Rules 246.x, 247.x relate to bitfields, the others speed up
5477 access to xdata mapped I/O devices.
5479 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5481 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5483 Cleaned up genPackBits and genUnpackBits and added two helper
5484 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5485 for literal assignments in genPackBits (thanks to Frieder for
5491 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5493 Fixed bug #748310 (pointer to function type mishandled when the
5494 function name is omitted). Also fixed a SIGSEGV when a function
5495 attribute (reentrant, etc) is used on a non-function or on a
5496 function but misplaced before the parameter list.
5498 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5500 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

5523 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5525 Made the constant following the "interrupt" keyword optional. If
5526 omitted, the function will not automatically be given an entry
5527 in the interrupt vector table (similar to #pragma NOIV, but
5528 less syntacticly kludgy). The interrupt number is also now
5529 range checked. Also fixed a bug in the high order bit example

6059 added if/endif conditional macros to remove options help
6060 messages from optionsTable when a port is not configured, added
6061 support for the PIc16 port in the ports table, when executing
6062 the compiler with no port specified on command line, a default
6063 port is selected with the new macro DEFAULT_PORT which is
6064 defined in port.h, in setDefaultOptions() linkOptions is removed
6065 from initialization assignment, since now it is a set,
6066 parseCmdLine uses setParseWithComma for linkOptions, in
6067 linkEdit() linkOptions are accessed with new function indexSet()
6068 which returns the i'th item of a set variable. See SDCCset.c, in
6069 linkEdit() when calling buildCmdLine(), added linkOptions as
6070 last argument. Now users can pass arguments to gplink via the
6071 -Wl option, main() uses pic16glue() to glue up pic16 programs

6084 * src/pic16/main.c: __config directives are commented out to stop
6085 gpasm complaining and test the linkage with gplink, _linkCmd and
6086 _asmCmd changed to be more gplink and gpasm friendly
6087 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6088 produced an error when parsed, peep rule 12 is added to utilize
6089 movff, but it is commented out since the pCode does not support
6090 yet a command with 2 address arguments
6092 2003-05-18 <johan AT balder>
6094 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7135 2003-01-04 <johan AT balder>
7137 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7139 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

7152 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7153 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7155 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7157 * in \sdcc\as\mcs51\ changed these files in order to create an
7158 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7159 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7160 following files to include the previous two files: aslink.dsp,
7161 Makefile.aslink, Makefile.bcc, and Makefile.in.
7163 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7164 .adb instead of .cdb
7166 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7168 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7169 value from option --iram-size.
7171 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7173 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7176 2002-09-18 <wiml AT hhhh.org>
7178 * SDCClrange.h: exposed setFromRange() and setToRange()
7179 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7180 packRegsForAccUse() (bug 542397)
7181 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7182 multiple times and emitting the fetch operations more than once
7183 added aopGetUsesAcc() function to allow binary operators to
7184 fetch their operands in the correct order; made genMinus() emit
7185 compact code for X = LITERAL - Y
7187 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7188 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7189 sprintf() in line 1267.
7191 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7192 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7195 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7196 Changes to aslink (All the changes are marked with 'JCF'):
7198 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7201 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7202 area BSEG. Also moves, if possible, the DATA area down into the internal
7203 ram so more space is available.
7205 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7208 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7209 not bytes. Function summary() which creates a memory usage summary
7210 file with extension .mem. Reports of overlaping stack and small stack
7211 size. If the space for the stack is less than 16 bytes aslink trows a
7214 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7215 the 8051. Option 'y' for memory summary output file.
7217 Changes to sdcc (All the changes are marked with 'JCF'):
7219 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7221 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7222 overlaying area for it (uses RegBankUsed[4]).
7224 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7225 bank zero as used by default. By default aslink locates the stack
7226 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7227 the creation of the .mem file. Delegates the allocation of data area
7228 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7229 the begining of the stack area to aslink.
7231 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7232 glue() in SDCCglue.c creates an area for it.
7234 2002-09-03 Borut Razem <borut.razem AT siol.net>
7235 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7236 sdcc/src/pic/glue.c:
7237 introduced atexit() handler for teporay files removal in case of
7238 errors, assertions, ...
7240 2002-08-29 Borut Razem <borut.razem AT siol.net>
7241 * sdcc/support/cpp2/auto-host_vc_in.h:
7242 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7243 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7244 Maybe there is a similar problem with BORLANDC? It should be checked!
7246 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7247 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7248 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7249 was not executed, and the compiler (cl) launched a warning:
7250 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7252 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7253 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7255 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7256 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7258 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7259 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7260 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7261 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7262 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7263 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7264 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7265 - added Release configuration in VS projects
7266 - review of compiler an linker options
7267 - VC .exe files are generated in bin_vc directory, not to interfere
7268 with binaries generated from other projects (cygwin, mingw, bcc ...)
7270 * sdcc/src/yacc.dsp: added
7272 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7273 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7274 and insert the version number definitions from .version
7276 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7278 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7279 added - genarate auto-host.h using auto-host_vc_in.h as template
7282 removed from CVS, generated automatically
7284 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7285 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7287 2002-08-11 Borut Razem <borut.razem AT siol.net>
7288 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7290 2002-08-10 Borut Razem <borut.razem AT siol.net>
7291 * src/SDCCmain.c (main):
7292 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7293 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7294 The consequence was that some temporary files were not removed.
7297 unification of code in functions tempfilename() and tempfile():
7298 function tempnam() is defined in Visual Studio 6.0 and .NET
7300 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7302 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7303 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7304 - removed compiler command line option /WX: Treats all warnings as errors
7305 - update a list of source files, included into the project
7307 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7308 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7309 changed project type to Generic Project so that can be correcly converted to VS.NET project
7311 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7313 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7315 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7317 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7318 added return 0 statements after assert() to make compiler happy
7320 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7321 added newline in the def file to keep MSC compiler satisfied
7323 * sdcc/src/z80/gen.c:
7324 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7325 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7326 - solved MSC error in function aopDump()
7328 * sdcc_vc.h: define PREFIX as "\\sdcc"
7330 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7331 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7334 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7335 - Rewrote the register banking algorithm.
7336 - Added pCode live-range analysis to registers (for now, only non-used and
7337 singly-used registers optimized away)
7339 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7341 * 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 2002-03-28 Johan Knol <johan AT balder>
7372 * src/SDCCval.c: fixed bug #532436
7374 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7376 Added "char *Processor" field to the port structure.
7379 Added -p option. Allows port dependent processor to be specified.
7382 Initialized the new field char *Processor field to NULL in all ports
7385 Compiler generated registers for interrupt context saving
7386 were not getting allocated.
7388 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7391 Fixed left shift. Will promote the left side of a left shift
7392 if a) left shifting more than size of operand or b) when assigned
7393 to something size > size of left side
7395 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7397 tons of changes. Register allocation has been
7398 rewritten. Added customization for the various PICs. Flow
7399 analysis is restructured. ...
7405 Added. device.c is a PIC port hack to accomodate variations
7408 2002-03-13 Michael Hope <michaelh AT vroom>
7410 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7412 2002-03-04 johanknol <johanknol AT manik>
