39 2005-03-20 Borut Razem <borut.razem AT siol.net>
41 * support/scripts/inc2h.pl: WIN32 port
43 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>

47 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
49 * device/include/stdint.h: added
50 * device/lib/abs.c: added
51 * device/lib/labs.c: added
52 * device/include/stdlib.h: added abs() and labs() prototypes
53 * device/lib/libsdcc.lib: added abs and labs
54 * device/include/float.h,
55 * device/lib/_fsmul.c,
56 * device/lib/printf_fast.c,
57 * device/lib/printf_tiny.c: updated comments
59 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
61 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
64 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
66 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
67 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
69 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
71 * device/lib/printf_large.c: removed inline assembly for portability and
72 readability. Use printf_fast if speed or size are more important.
73 * src/pic16/gen.c: removed conditions around use of DEBUGpc
74 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
76 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
78 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
79 prevent compiler warning
81 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
83 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
84 moved to level 0 and declared as static. Also they are explicit
85 placed in access bank. This was necessery because some times they
86 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
87 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
88 optimizations. Currently only compare to unsigned char is implemented,
89 * src/pic16/gen.c: added fReturnIdx array,
90 * (struct resolvedIfx) is moved to gen.h and made public,
91 * (struct _G): added sregsAlloc and sregsAllocSet fields,
92 * (aopForSym): added an optimization to directly store in stack of
93 the operand of a SEND iCode,
94 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
95 but as registers instead (AOP_REG) using the fReturnIdx array,
96 * (pic16_freeAsmop): remove the freed register from the
98 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
100 * (pic16_popGetTempRegCond): changed function prototype, now
101 function takes also a bitVector argument v which holds the current
102 set of registers that are allocated for stack access by aopForSym,
103 registers allocated in aopForSym for accessing stack symbols are not
104 any more part of the functions usedRegs field,
105 * (genCall): some times aopOp is called for a stack variable to be
106 send, aopForSym might perform the push, if this is true make sure
107 that genCall doesn't push the variable twice by testing _G.resDirect,
108 * (genFunction): changed testing for unspecified interrupt number
109 from 256 to INTNO_UNSPEC,
110 * modified selection scheme of frame pointer generation. Previously
111 if function did use local registers a frame pointer was generated,
112 now a frame pointer is generated only if function has arguments
113 (that need PLUSW2 register access), or has stack arguments, or the
114 compiler is not instructed to omit the frame pointer,
115 * (genEndFunction): before restoring local registers that were saved
116 in the function preamble, also restore the registers that *might*
117 have been allocated for stack access,
118 * (genRet): removed some old comments,
119 * (genCmp, the active (RN's) version): added a call to the
120 pic16_genCmp_special function to perform the compare with a more
121 robust and optimized way,
122 * (genInline): a feature has been added in inline code generation,
123 which allows a wildcard variable substitution when writing inline
124 assembly. Code is incomplete and experimental therefore undocumented,
125 * (genCast): changed order of aopOp for result and right to allow
126 aopForSym to directly load the result if possible,
127 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
128 perform an optimized compare on some selected special occasions,
129 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
130 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
131 generate an IVT any more,
132 * src/pic16/main.c (pic16_optionsTable): added command line option
134 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
135 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
137 * src/pic16/NOTES: Raphael Neider added in list of active developers
138 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
139 jumptable_end to prevent bug #,
140 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
141 inCond and outCond fields,
142 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
143 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
144 turn off register spilling,
145 * (packRegsForOneUse): synced with other ports' versions although it
146 is not used currently,
147 * (pic16_packRegisters): added an optimization while reading
148 structure bitfields, some registers may be saved (malloc code is
149 decreased by 80 bytes)
151 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
153 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
154 left is a bitfield, if yes, then don't optimize assignment. Perhaps
155 this can be optimized more?
157 2005-03-10 Raphael Neider <rneider AT web.de>
159 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
160 genNearPointerGet): (hopefully) fixed access to bitfields via
161 pointers (p->bitN = x; and x = p->bitN; failed)

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

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

3881 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3882 loaded with the linker search paths (-L arguments) and the libraries
3883 to be linked with the current source (-l arguments). Changes
3884 currently will affect only the pic16 port.
3885 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3886 include path the port specific paths and port specific libraries,
3887 * gplink command now contains the $3 argument,
3888 * src/pic16/device.h,
3889 * src/pic16/device.c,: structure PIC_device is made public and

3905 Documenting changes from previous commits.
3906 * configure.in (version 1.56),
3907 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3908 when generating output files to configure the pic16 library,
3909 but now I've commented it out, since gputils aren't installed in the
3910 SF compile farm, so library won't compile
3912 * device/lib/Makefile.in (version 1.56): initially I've added in
3913 target 'all' the prerequestive 'model-pic16' so it compiled the
3914 pic16 library, but now I've commented it out for the same reasons
3916 * added targets 'model-pic16' and 'objects-pic16' to compile the
3918 * added target 'port-specific-objects-pic16' to handle the
3919 generated libraries and copy them into the build/ directory
3920 * added target 'clean-intermediate-pic16' to clean intermediate
3921 files into pic16 directory
3922 * in target 'installdirs' added line to create directory pic16 in

3926 added lines to copy all header files to installation path,
3927 * in target 'installdirs' added line create directory for pic16
3928 headers in the installation path

3944 option so that it actually works. Made it specific to the z80, since
3945 the gbz80 doesn't have these kinds of I/O ports.
3947 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4055 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
4056 UPPER for immediate operands,
4057 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4059 * src/pic16/peeph.def: all peepholes with movff are commented out,
4060 because there is a problem in the pcode peep optimizer,
4061 * src/pic16/ralloc.c: the register allocator can now reuse local
4062 function symbols for another function. This saves register usage.
4063 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4065 Added file src/pic16/NOTES with information about program writing on
4066 the current port version.

4154 include information about variables allocated to the overlay
4157 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4159 * as/mcs51/lkmain.c: Help about -Y option

4169 LEFT_OP (left shift)
4171 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4173 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4174 (default behaviour).
4176 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4178 A python script to validate compiler diagnostic messages. It can be
4179 used to verify that sdcc complains about bad c source code and
4180 gives a good location of the error.
4181 * support/valdiag/Makefile,
4182 * support/valdiag/valdiag.py,
4183 * support/valdiag/tests/*
4185 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4200 Bug reported from Jesus Calvino-Fraga
4202 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4204 * sdcc.spec: updated
4205 * device/include/Makefile.in: don't install CVS directories
4206 * device/lib/Makefile.in: added removal of CVS directories after install
4207 * doc/Makefile: fixed install, added local_icons
4208 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4209 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4210 * src/ds390/gen.c (genRightShift): fixed bug #870788
4211 * src/SDCCast.c (decorateType): fixed bug #870781
4213 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4215 PIC16 port related changes:
4216 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4217 added variable stackPos,
4219 * gen.c: genCall, assignResultValue: added support for
4220 pushing/retrieving function parameters to/from stack,
4221 genFunction,genEndFunction: setup stack frame for the
4223 genAddrOf: will be changed according to bug 863624
4225 * added files genutils.c and genutils.h which contain gen*
4226 debugged and optimised functions extracted from gen.c
4228 * glue.c: added variable 'externs' which holds extern symbols,
4229 pic16emitRegularMap: is modified to properly handle relocatable
4230 symbols under the new scheme,
4231 pic16createInterruptVect: is modified
4232 pic16printPublics: is modified to emit 'global' assembler directives,
4233 added pic16_printExterns to print extern symbols,
4234 pic16glue: initializes stack/frame pointer in the beginning of
4235 the assembly output. Temporary hack, will be corrected later,
4236 because gplink yet does not support stack and SDCC does not
4237 yet support a type of crt0.o object to create the final binary.
4239 * Removed many lines that contain 8051 legacy code.
4240 * The code is finally placed under a 'code' directive.
4241 * Added port specific options.
4243 * _process_pragma: simplified since now we do not need *special*
4244 include file to define SFR registers. But a separate header
4245 will be needed. This will be developed later.
4246 * _pic16_parseOptions: added, parses port specific options:
4247 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4248 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4249 --preplace-udata-with=
4251 * _pic16_setDefaultOptions: modified to initialize section names,
4252 but hack is temporarly out of order since it needs improvement.
4253 * _pic16_genAssemblerPreamble: configuration words are emitted by
4254 their address instead of their name. This part is incomplete and
4255 supports only the 18Fxx2 devices. Other devices will emit an error
4256 during assembly since they do not contain the same set of config
4258 * _pic16_genIVT: is modified,
4260 * pcode.c: added definitions for some hardware registers that are needed
4262 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4263 All PCI entries are updated. Now LFSR is supported.
4264 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4265 * added pic16_newpCodeOpLit2 to support instructions with
4266 two literal arguments
4267 * pic16_pCode2str: corrected code that emits assembler instructions
4268 with two literal operands and those that have an access bit modifier
4269 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4270 this fixes a bug which caused some labels to be lost, when an
4271 assembler directive was added, i.e. banksel,
4272 * pic16_FixRegisterBanking: improved logic that causes the insertion
4274 * InlineFunction: functions that are called once, are not any more
4275 inlined. This can be a port option in the future,
4277 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4279 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4280 hold the corresponding uninitialized symbols,
4281 * pic16_allocProcessorRegister: registers have explicit marked the
4283 * pic16_allocInternalRegister: registers are explicit marked as
4285 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4286 processing list, so bit registers were lost,
4289 * ralloc.h: added field 'accessBank' and original symbol operand
4290 in register definition,
4291 * removed the field isMapped from register definition,
4293 ** Several functions have been removed from various sources:
4294 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4295 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4296 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4297 pic16_assignRelocatableRegisters
4299 ** others have been introduced:
4300 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4301 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4303 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4305 * support/scripts/inc2h.pl: changed definition of BIT_AT
4306 to emit 'sbit at' instead of 'bit at'. This was a request.
4308 PIC16 port related preliminary changes:
4309 * gen.c: prefixed function popRegFromString with
4310 pic16_ and all references to it corrected
4311 * pcode.c: all pic16_pc_* hardware registers prefixed
4312 with underscore (_),
4313 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4314 * ralloc.c: newReg(): when register is REG_SFR then
4315 set address to rIdx,
4316 pic16_allocProcessorRegister(): marks register wasUsed=0
4317 pic16_writeUsedRegs(): added a call to assign processor
4318 registers via pic16_assignFixedRegisters
4320 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4322 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4323 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4324 variables in unused register banks. Also the SSEG is placed
4325 wherever there is enough space for it, and IDATA can be anywhere
4326 in internal RAM. For now compile using -Wl-Y[stack_size].
4327 The mem file is different for this option as well, since it
4328 makes no sense of talking about DSEG lenght.
4330 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4332 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4333 in certain cases, e.g. when ROM assignment, patch provided
4334 from Albert den Haan.
4336 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5222 support for standard C idiom of memory mapped variables; for
5223 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5224 to xdata int at 0x1234 tempvar = 1.
5225 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5226 provided by Akiya ISHIDA

5338 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5339 fetching of the pointer
5340 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5341 copied from genNearPointerSet()
5342 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5343 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5344 If they pop r0/r1 they must be called in the opposite order than aopOp().
5345 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"

5357 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5359 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5360 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5361 type for bits was changed. It resulted in bit variables becoming
5362 global, which is not permitted in PIC 14 assembly output.
5364 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5366 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5379 A few small changes that speed up the peephole optimizer.
5383 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5385 Try to make the peephole optimizer smarter by maintaining
5386 an association between the assembly source code and the
5387 iCodes that originated them. Put this information to use
5388 with a new peephole rule condition "notVolatile" so that
5389 the rules can be aggressive yet still safe.
5394 * src/mcs51/peeph.def
5396 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5400 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5401 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5402 if the left or right operand symbols have the accuse flag set.
5404 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5406 Changed the type of the result of the ! (NOT) operator to char;
5407 previously it returned the same type as the source. This allows
5408 us to eliminate all the genFloatNot functions (all of its target
5409 implementations were very buggy) since !float can use the same
5412 * src/SDCCicode.c (ast2iCode): ! returns char

5421 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5422 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5423 during interrupts. Ensure WSAVE is located at a shared bank address.
5424 2. Fixed page selection in some places
5425 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5426 the registers name strings.
5427 4. Fixed "signed / unsigned compare" compiler warnings.
5428 5. The PIC port manages its own allocation of the general purpose
5429 registers, but makes no attempt to reuse them. As a result when
5430 compiling it soon runs out of general purpose registers. Some
5431 additional code was added to the files pcode.c and device.c to walk
5432 through the function call tree and rename the registers so that they
5442 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5443 genPlus() & genMinus() when the result is the same as left or right

5449 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5451 Made bitfield a distinct type from bit so that bitfields
5452 convert as per ANSI C and bits retain their traditional
5453 boolean style behaviour. Implemented bitfield support in
5461 * src/ds390/gen.c: bit v bitfield split
5462 * src/z80/gen.c: New support for bitfields
5463 * support/regression/tests/bitfields.c: reenabled z80,
5466 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5468 Rules 246.x, 247.x relate to bitfields, the others speed up
5469 access to xdata mapped I/O devices.
5471 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5473 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5475 Cleaned up genPackBits and genUnpackBits and added two helper
5476 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5477 for literal assignments in genPackBits (thanks to Frieder for
5483 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5485 Fixed bug #748310 (pointer to function type mishandled when the
5486 function name is omitted). Also fixed a SIGSEGV when a function
5487 attribute (reentrant, etc) is used on a non-function or on a
5488 function but misplaced before the parameter list.
5490 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5492 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5493 * support/Util/SDCCerr.h,

5515 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5517 Made the constant following the "interrupt" keyword optional. If
5518 omitted, the function will not automatically be given an entry
5519 in the interrupt vector table (similar to #pragma NOIV, but
5520 less syntacticly kludgy). The interrupt number is also now
5521 range checked. Also fixed a bug in the high order bit example

5535 * src/SDCCicode.c (operandOperation): rewritten some ops
5536 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5537 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5539 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5540 be re-activated by defining REDUCE_LITERALS)
5541 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5542 unsigned, but are signed by default
5543 * src/SDCCval.c (constVal): rearranged
5544 * src/SDCCval.c (valMod): preliminary fix
5545 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6051 added if/endif conditional macros to remove options help
6052 messages from optionsTable when a port is not configured, added
6053 support for the PIc16 port in the ports table, when executing
6054 the compiler with no port specified on command line, a default
6055 port is selected with the new macro DEFAULT_PORT which is
6056 defined in port.h, in setDefaultOptions() linkOptions is removed
6057 from initialization assignment, since now it is a set,
6058 parseCmdLine uses setParseWithComma for linkOptions, in
6059 linkEdit() linkOptions are accessed with new function indexSet()
6060 which returns the i'th item of a set variable. See SDCCset.c, in
6061 linkEdit() when calling buildCmdLine(), added linkOptions as
6062 last argument. Now users can pass arguments to gplink via the
6063 -Wl option, main() uses pic16glue() to glue up pic16 programs

6076 * src/pic16/main.c: __config directives are commented out to stop
6077 gpasm complaining and test the linkage with gplink, _linkCmd and
6078 _asmCmd changed to be more gplink and gpasm friendly
6079 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6080 produced an error when parsed, peep rule 12 is added to utilize
6081 movff, but it is commented out since the pCode does not support
6082 yet a command with 2 address arguments
6084 2003-05-18 <johan AT balder>
6086 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6105 Fixed so you can set breakpoints prior to run, run does not stop
6106 on entry now. Add tbreak. Other enhancements and fixes for use
6109 2003-05-12 Borut Razem <borut.razem AT siol.net>
6111 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6113 2003-05-11 Borut Razem <borut.razem AT siol.net>
6115 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

7125 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7127 2003-01-04 <johan AT balder>
7129 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7131 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

7144 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7145 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7147 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7149 * in \sdcc\as\mcs51\ changed these files in order to create an
7150 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7151 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7152 following files to include the previous two files: aslink.dsp,
7153 Makefile.aslink, Makefile.bcc, and Makefile.in.
7155 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7156 .adb instead of .cdb
7158 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7160 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7161 value from option --iram-size.
7163 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7165 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7168 2002-09-18 <wiml AT hhhh.org>
7170 * SDCClrange.h: exposed setFromRange() and setToRange()
7171 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7172 packRegsForAccUse() (bug 542397)
7173 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7174 multiple times and emitting the fetch operations more than once
7175 added aopGetUsesAcc() function to allow binary operators to
7176 fetch their operands in the correct order; made genMinus() emit
7177 compact code for X = LITERAL - Y
7179 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7180 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7181 sprintf() in line 1267.
7183 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7184 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7187 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7188 Changes to aslink (All the changes are marked with 'JCF'):
7190 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7193 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7194 area BSEG. Also moves, if possible, the DATA area down into the internal
7195 ram so more space is available.
7197 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7200 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7201 not bytes. Function summary() which creates a memory usage summary
7202 file with extension .mem. Reports of overlaping stack and small stack
7203 size. If the space for the stack is less than 16 bytes aslink trows a
7206 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7207 the 8051. Option 'y' for memory summary output file.
7209 Changes to sdcc (All the changes are marked with 'JCF'):
7211 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7213 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7214 overlaying area for it (uses RegBankUsed[4]).
7216 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7217 bank zero as used by default. By default aslink locates the stack
7218 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7219 the creation of the .mem file. Delegates the allocation of data area
7220 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7221 the begining of the stack area to aslink.
7223 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7224 glue() in SDCCglue.c creates an area for it.
7226 2002-09-03 Borut Razem <borut.razem AT siol.net>
7227 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7228 sdcc/src/pic/glue.c:
7229 introduced atexit() handler for teporay files removal in case of
7230 errors, assertions, ...
7232 2002-08-29 Borut Razem <borut.razem AT siol.net>
7233 * sdcc/support/cpp2/auto-host_vc_in.h:
7234 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7235 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7236 Maybe there is a similar problem with BORLANDC? It should be checked!
7238 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7239 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7240 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7241 was not executed, and the compiler (cl) launched a warning:
7242 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7244 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7245 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7247 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7248 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7250 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7251 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7252 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7253 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7254 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7255 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7256 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7257 - added Release configuration in VS projects
7258 - review of compiler an linker options
7259 - VC .exe files are generated in bin_vc directory, not to interfere
7260 with binaries generated from other projects (cygwin, mingw, bcc ...)
7262 * sdcc/src/yacc.dsp: added
7264 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7265 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7266 and insert the version number definitions from .version
7268 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7270 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7271 added - genarate auto-host.h using auto-host_vc_in.h as template
7274 removed from CVS, generated automatically
7276 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7277 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7279 2002-08-11 Borut Razem <borut.razem AT siol.net>
7280 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7282 2002-08-10 Borut Razem <borut.razem AT siol.net>
7283 * src/SDCCmain.c (main):
7284 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7285 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7286 The consequence was that some temporary files were not removed.
7289 unification of code in functions tempfilename() and tempfile():
7290 function tempnam() is defined in Visual Studio 6.0 and .NET
7292 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7294 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7295 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7296 - removed compiler command line option /WX: Treats all warnings as errors
7297 - update a list of source files, included into the project
7299 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7300 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7301 changed project type to Generic Project so that can be correcly converted to VS.NET project
7303 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7305 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7307 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7309 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7310 added return 0 statements after assert() to make compiler happy
7312 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7313 added newline in the def file to keep MSC compiler satisfied
7315 * sdcc/src/z80/gen.c:
7316 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7317 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7318 - solved MSC error in function aopDump()
7320 * sdcc_vc.h: define PREFIX as "\\sdcc"
7322 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7323 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7325 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7326 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7327 - Rewrote the register banking algorithm.
7328 - Added pCode live-range analysis to registers (for now, only non-used and
7329 singly-used registers optimized away)
7331 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7333 * 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.

7362 2002-03-28 Johan Knol <johan AT balder>
7364 * src/SDCCval.c: fixed bug #532436
7366 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7368 Added "char *Processor" field to the port structure.
7371 Added -p option. Allows port dependent processor to be specified.
7374 Initialized the new field char *Processor field to NULL in all ports
7377 Compiler generated registers for interrupt context saving
7378 were not getting allocated.
7380 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7383 Fixed left shift. Will promote the left side of a left shift
7384 if a) left shifting more than size of operand or b) when assigned
7385 to something size > size of left side
7387 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7389 tons of changes. Register allocation has been
7390 rewritten. Added customization for the various PICs. Flow
7391 analysis is restructured. ...
7397 Added. device.c is a PIC port hack to accomodate variations

7498 Previous fix was not good. basic blocks that have "break" or "return" are
7499 not really partof a loop , but live ranges used in these blocks should
