27 * src/SDCCcflow.c (*),
29 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
30 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
31 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
32 immedDom() returning wrong block; probably fixes bug #1160833)
34 2005-03-20 Borut Razem <borut.razem AT siol.net>
36 * support/scripts/inc2h.pl: WIN32 port
38 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
40 * device/lib/makefile.in: added abs.c and labs.c
42 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
44 * device/include/stdint.h: added
45 * device/lib/abs.c: added
46 * device/lib/labs.c: added
47 * device/include/stdlib.h: added abs() and labs() prototypes
48 * device/lib/libsdcc.lib: added abs and labs
49 * device/include/float.h,
50 * device/lib/_fsmul.c,
51 * device/lib/printf_fast.c,

54 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
56 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
59 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
61 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
62 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
64 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
66 * device/lib/printf_large.c: removed inline assembly for portability and
67 readability. Use printf_fast if speed or size are more important.
68 * src/pic16/gen.c: removed conditions around use of DEBUGpc
69 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
71 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
73 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
74 prevent compiler warning
76 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
78 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
79 moved to level 0 and declared as static. Also they are explicit
80 placed in access bank. This was necessery because some times they
81 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
82 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
83 optimizations. Currently only compare to unsigned char is implemented,
84 * src/pic16/gen.c: added fReturnIdx array,
85 * (struct resolvedIfx) is moved to gen.h and made public,
86 * (struct _G): added sregsAlloc and sregsAllocSet fields,
87 * (aopForSym): added an optimization to directly store in stack of
88 the operand of a SEND iCode,
89 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
90 but as registers instead (AOP_REG) using the fReturnIdx array,
91 * (pic16_freeAsmop): remove the freed register from the
93 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
95 * (pic16_popGetTempRegCond): changed function prototype, now
96 function takes also a bitVector argument v which holds the current
97 set of registers that are allocated for stack access by aopForSym,
98 registers allocated in aopForSym for accessing stack symbols are not
99 any more part of the functions usedRegs field,
100 * (genCall): some times aopOp is called for a stack variable to be
101 send, aopForSym might perform the push, if this is true make sure
102 that genCall doesn't push the variable twice by testing _G.resDirect,
103 * (genFunction): changed testing for unspecified interrupt number
104 from 256 to INTNO_UNSPEC,
105 * modified selection scheme of frame pointer generation. Previously
106 if function did use local registers a frame pointer was generated,
107 now a frame pointer is generated only if function has arguments
108 (that need PLUSW2 register access), or has stack arguments, or the
109 compiler is not instructed to omit the frame pointer,
110 * (genEndFunction): before restoring local registers that were saved
111 in the function preamble, also restore the registers that *might*
112 have been allocated for stack access,
113 * (genRet): removed some old comments,
114 * (genCmp, the active (RN's) version): added a call to the
115 pic16_genCmp_special function to perform the compare with a more
116 robust and optimized way,
117 * (genInline): a feature has been added in inline code generation,
118 which allows a wildcard variable substitution when writing inline
119 assembly. Code is incomplete and experimental therefore undocumented,
120 * (genCast): changed order of aopOp for result and right to allow
121 aopForSym to directly load the result if possible,
122 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
123 perform an optimized compare on some selected special occasions,
124 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
125 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
126 generate an IVT any more,
127 * src/pic16/main.c (pic16_optionsTable): added command line option
129 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
130 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
132 * src/pic16/NOTES: Raphael Neider added in list of active developers
133 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
134 jumptable_end to prevent bug #,
135 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
136 inCond and outCond fields,
137 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
138 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
139 turn off register spilling,
140 * (packRegsForOneUse): synced with other ports' versions although it
141 is not used currently,
142 * (pic16_packRegisters): added an optimization while reading
143 structure bitfields, some registers may be saved (malloc code is
144 decreased by 80 bytes)
146 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
148 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
149 left is a bitfield, if yes, then don't optimize assignment. Perhaps
150 this can be optimized more?
152 2005-03-10 Raphael Neider <rneider AT web.de>
154 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
155 genNearPointerGet): (hopefully) fixed access to bitfields via
156 pointers (p->bitN = x; and x = p->bitN; failed)

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

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

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

3874 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
3876 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3877 loaded with the linker search paths (-L arguments) and the libraries
3878 to be linked with the current source (-l arguments). Changes
3879 currently will affect only the pic16 port.
3880 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3881 include path the port specific paths and port specific libraries,
3882 * gplink command now contains the $3 argument,
3883 * src/pic16/device.h,
3884 * src/pic16/device.c,: structure PIC_device is made public and
3885 renamed to PIC16_device, the same for variable Pics which is renamed

3900 Documenting changes from previous commits.
3901 * configure.in (version 1.56),
3902 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3903 when generating output files to configure the pic16 library,
3904 but now I've commented it out, since gputils aren't installed in the
3905 SF compile farm, so library won't compile
3907 * device/lib/Makefile.in (version 1.56): initially I've added in
3908 target 'all' the prerequestive 'model-pic16' so it compiled the
3909 pic16 library, but now I've commented it out for the same reasons
3911 * added targets 'model-pic16' and 'objects-pic16' to compile the
3913 * added target 'port-specific-objects-pic16' to handle the
3914 generated libraries and copy them into the build/ directory
3915 * added target 'clean-intermediate-pic16' to clean intermediate
3916 files into pic16 directory
3917 * in target 'installdirs' added line to create directory pic16 in
3918 the installation path

3921 added lines to copy all header files to installation path,
3922 * in target 'installdirs' added line create directory for pic16
3923 headers in the installation path

3939 option so that it actually works. Made it specific to the z80, since
3940 the gbz80 doesn't have these kinds of I/O ports.
3942 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3944 * device/include/z180.h,

3968 via literal number. The symbol is placed in the corresponding
3969 position of the data ram
3970 * (pic16_dump_section): relocatable and absolute uninitialized
3971 data are now emitted in sorted order to reduce section naming,
3972 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3973 weren't marked as being in the access bank,

4050 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
4051 UPPER for immediate operands,
4052 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
4054 * src/pic16/peeph.def: all peepholes with movff are commented out,
4055 because there is a problem in the pcode peep optimizer,
4056 * src/pic16/ralloc.c: the register allocator can now reuse local
4057 function symbols for another function. This saves register usage.
4058 * src/pic16/ralloc.h: added flag isLocal in structure regs,
4060 Added file src/pic16/NOTES with information about program writing on
4061 the current port version.

4149 include information about variables allocated to the overlay
4152 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4154 * as/mcs51/lkmain.c: Help about -Y option

4164 LEFT_OP (left shift)
4166 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4168 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4169 (default behaviour).
4171 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4173 A python script to validate compiler diagnostic messages. It can be
4174 used to verify that sdcc complains about bad c source code and
4175 gives a good location of the error.
4176 * support/valdiag/Makefile,
4177 * support/valdiag/valdiag.py,
4178 * support/valdiag/tests/*
4180 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4197 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4199 * sdcc.spec: updated
4200 * device/include/Makefile.in: don't install CVS directories
4201 * device/lib/Makefile.in: added removal of CVS directories after install
4202 * doc/Makefile: fixed install, added local_icons
4203 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4204 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4205 * src/ds390/gen.c (genRightShift): fixed bug #870788

4208 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4210 PIC16 port related changes:
4211 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4212 added variable stackPos,
4214 * gen.c: genCall, assignResultValue: added support for
4215 pushing/retrieving function parameters to/from stack,
4216 genFunction,genEndFunction: setup stack frame for the
4218 genAddrOf: will be changed according to bug 863624
4220 * added files genutils.c and genutils.h which contain gen*
4221 debugged and optimised functions extracted from gen.c
4223 * glue.c: added variable 'externs' which holds extern symbols,
4224 pic16emitRegularMap: is modified to properly handle relocatable
4225 symbols under the new scheme,
4226 pic16createInterruptVect: is modified
4227 pic16printPublics: is modified to emit 'global' assembler directives,
4228 added pic16_printExterns to print extern symbols,
4229 pic16glue: initializes stack/frame pointer in the beginning of
4230 the assembly output. Temporary hack, will be corrected later,
4231 because gplink yet does not support stack and SDCC does not
4232 yet support a type of crt0.o object to create the final binary.
4234 * Removed many lines that contain 8051 legacy code.
4235 * The code is finally placed under a 'code' directive.
4236 * Added port specific options.
4238 * _process_pragma: simplified since now we do not need *special*
4239 include file to define SFR registers. But a separate header
4240 will be needed. This will be developed later.
4241 * _pic16_parseOptions: added, parses port specific options:
4242 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4243 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4244 --preplace-udata-with=
4246 * _pic16_setDefaultOptions: modified to initialize section names,
4247 but hack is temporarly out of order since it needs improvement.
4248 * _pic16_genAssemblerPreamble: configuration words are emitted by
4249 their address instead of their name. This part is incomplete and
4250 supports only the 18Fxx2 devices. Other devices will emit an error
4251 during assembly since they do not contain the same set of config
4253 * _pic16_genIVT: is modified,
4255 * pcode.c: added definitions for some hardware registers that are needed
4257 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4258 All PCI entries are updated. Now LFSR is supported.
4259 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4260 * added pic16_newpCodeOpLit2 to support instructions with
4261 two literal arguments
4262 * pic16_pCode2str: corrected code that emits assembler instructions
4263 with two literal operands and those that have an access bit modifier
4264 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4265 this fixes a bug which caused some labels to be lost, when an
4266 assembler directive was added, i.e. banksel,
4267 * pic16_FixRegisterBanking: improved logic that causes the insertion
4269 * InlineFunction: functions that are called once, are not any more
4270 inlined. This can be a port option in the future,
4272 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4274 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4275 hold the corresponding uninitialized symbols,
4276 * pic16_allocProcessorRegister: registers have explicit marked the
4278 * pic16_allocInternalRegister: registers are explicit marked as
4280 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4281 processing list, so bit registers were lost,
4284 * ralloc.h: added field 'accessBank' and original symbol operand
4285 in register definition,
4286 * removed the field isMapped from register definition,
4288 ** Several functions have been removed from various sources:
4289 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4290 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4291 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4292 pic16_assignRelocatableRegisters
4294 ** others have been introduced:
4295 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4296 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4298 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4300 * support/scripts/inc2h.pl: changed definition of BIT_AT
4301 to emit 'sbit at' instead of 'bit at'. This was a request.
4303 PIC16 port related preliminary changes:
4304 * gen.c: prefixed function popRegFromString with
4305 pic16_ and all references to it corrected
4306 * pcode.c: all pic16_pc_* hardware registers prefixed
4307 with underscore (_),
4308 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4309 * ralloc.c: newReg(): when register is REG_SFR then
4310 set address to rIdx,
4311 pic16_allocProcessorRegister(): marks register wasUsed=0
4312 pic16_writeUsedRegs(): added a call to assign processor
4313 registers via pic16_assignFixedRegisters
4315 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4317 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4318 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4319 variables in unused register banks. Also the SSEG is placed
4320 wherever there is enough space for it, and IDATA can be anywhere
4321 in internal RAM. For now compile using -Wl-Y[stack_size].
4322 The mem file is different for this option as well, since it
4323 makes no sense of talking about DSEG lenght.
4325 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4327 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4328 in certain cases, e.g. when ROM assignment, patch provided
4329 from Albert den Haan.
4331 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5216 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
5217 support for standard C idiom of memory mapped variables; for
5218 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5219 to xdata int at 0x1234 tempvar = 1.
5220 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5221 provided by Akiya ISHIDA

5332 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
5333 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5334 fetching of the pointer
5335 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5336 copied from genNearPointerSet()
5337 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5338 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5339 If they pop r0/r1 they must be called in the opposite order than aopOp().

5350 these ports have their own __sdcc_external_start()
5352 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5354 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5355 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5356 type for bits was changed. It resulted in bit variables becoming
5357 global, which is not permitted in PIC 14 assembly output.
5359 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5361 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5374 A few small changes that speed up the peephole optimizer.
5378 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5380 Try to make the peephole optimizer smarter by maintaining
5381 an association between the assembly source code and the
5382 iCodes that originated them. Put this information to use
5383 with a new peephole rule condition "notVolatile" so that
5384 the rules can be aggressive yet still safe.
5389 * src/mcs51/peeph.def
5391 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5395 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5396 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5397 if the left or right operand symbols have the accuse flag set.
5399 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5401 Changed the type of the result of the ! (NOT) operator to char;
5402 previously it returned the same type as the source. This allows
5403 us to eliminate all the genFloatNot functions (all of its target
5404 implementations were very buggy) since !float can use the same
5407 * src/SDCCicode.c (ast2iCode): ! returns char

5414 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5416 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5417 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5418 during interrupts. Ensure WSAVE is located at a shared bank address.
5419 2. Fixed page selection in some places
5420 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5421 the registers name strings.
5422 4. Fixed "signed / unsigned compare" compiler warnings.
5423 5. The PIC port manages its own allocation of the general purpose
5424 registers, but makes no attempt to reuse them. As a result when
5425 compiling it soon runs out of general purpose registers. Some
5426 additional code was added to the files pcode.c and device.c to walk
5427 through the function call tree and rename the registers so that they
5437 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5438 genPlus() & genMinus() when the result is the same as left or right

5444 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5446 Made bitfield a distinct type from bit so that bitfields
5447 convert as per ANSI C and bits retain their traditional
5448 boolean style behaviour. Implemented bitfield support in
5456 * src/ds390/gen.c: bit v bitfield split
5457 * src/z80/gen.c: New support for bitfields
5458 * support/regression/tests/bitfields.c: reenabled z80,
5461 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5463 Rules 246.x, 247.x relate to bitfields, the others speed up
5464 access to xdata mapped I/O devices.
5466 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5468 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5470 Cleaned up genPackBits and genUnpackBits and added two helper
5471 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5472 for literal assignments in genPackBits (thanks to Frieder for
5478 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5480 Fixed bug #748310 (pointer to function type mishandled when the
5481 function name is omitted). Also fixed a SIGSEGV when a function
5482 attribute (reentrant, etc) is used on a non-function or on a
5483 function but misplaced before the parameter list.
5485 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5487 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5488 * support/Util/SDCCerr.h,
5489 * support/Util/SDCCerr.c: Added func attr misuse error msg

5510 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5512 Made the constant following the "interrupt" keyword optional. If
5513 omitted, the function will not automatically be given an entry
5514 in the interrupt vector table (similar to #pragma NOIV, but
5515 less syntacticly kludgy). The interrupt number is also now
5516 range checked. Also fixed a bug in the high order bit example

5530 * src/SDCCicode.c (operandOperation): rewritten some ops
5531 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5532 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5534 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5535 be re-activated by defining REDUCE_LITERALS)
5536 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5537 unsigned, but are signed by default
5538 * src/SDCCval.c (constVal): rearranged
5539 * src/SDCCval.c (valMod): preliminary fix
5540 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6046 added if/endif conditional macros to remove options help
6047 messages from optionsTable when a port is not configured, added
6048 support for the PIc16 port in the ports table, when executing
6049 the compiler with no port specified on command line, a default
6050 port is selected with the new macro DEFAULT_PORT which is
6051 defined in port.h, in setDefaultOptions() linkOptions is removed
6052 from initialization assignment, since now it is a set,
6053 parseCmdLine uses setParseWithComma for linkOptions, in
6054 linkEdit() linkOptions are accessed with new function indexSet()
6055 which returns the i'th item of a set variable. See SDCCset.c, in
6056 linkEdit() when calling buildCmdLine(), added linkOptions as
6057 last argument. Now users can pass arguments to gplink via the
6058 -Wl option, main() uses pic16glue() to glue up pic16 programs

6071 * src/pic16/main.c: __config directives are commented out to stop
6072 gpasm complaining and test the linkage with gplink, _linkCmd and
6073 _asmCmd changed to be more gplink and gpasm friendly
6074 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6075 produced an error when parsed, peep rule 12 is added to utilize
6076 movff, but it is commented out since the pCode does not support
6077 yet a command with 2 address arguments
6079 2003-05-18 <johan AT balder>
6081 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6100 Fixed so you can set breakpoints prior to run, run does not stop
6101 on entry now. Add tbreak. Other enhancements and fixes for use
6104 2003-05-12 Borut Razem <borut.razem AT siol.net>
6106 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6108 2003-05-11 Borut Razem <borut.razem AT siol.net>
6110 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

7116 * src/SDCCicode.c: fixed array add
7118 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7119 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7120 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7122 2003-01-04 <johan AT balder>
7124 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7126 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7127 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7129 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

7139 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7140 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7142 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7144 * in \sdcc\as\mcs51\ changed these files in order to create an
7145 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7146 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7147 following files to include the previous two files: aslink.dsp,
7148 Makefile.aslink, Makefile.bcc, and Makefile.in.
7150 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7151 .adb instead of .cdb
7153 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7155 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7156 value from option --iram-size.
7158 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7160 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7163 2002-09-18 <wiml AT hhhh.org>
7165 * SDCClrange.h: exposed setFromRange() and setToRange()
7166 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7167 packRegsForAccUse() (bug 542397)
7168 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7169 multiple times and emitting the fetch operations more than once
7170 added aopGetUsesAcc() function to allow binary operators to
7171 fetch their operands in the correct order; made genMinus() emit
7172 compact code for X = LITERAL - Y
7174 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7175 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7176 sprintf() in line 1267.
7178 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7179 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7182 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7183 Changes to aslink (All the changes are marked with 'JCF'):
7185 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7188 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7189 area BSEG. Also moves, if possible, the DATA area down into the internal
7190 ram so more space is available.
7192 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7195 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7196 not bytes. Function summary() which creates a memory usage summary
7197 file with extension .mem. Reports of overlaping stack and small stack
7198 size. If the space for the stack is less than 16 bytes aslink trows a
7201 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7202 the 8051. Option 'y' for memory summary output file.
7204 Changes to sdcc (All the changes are marked with 'JCF'):
7206 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7208 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7209 overlaying area for it (uses RegBankUsed[4]).
7211 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7212 bank zero as used by default. By default aslink locates the stack
7213 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7214 the creation of the .mem file. Delegates the allocation of data area
7215 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7216 the begining of the stack area to aslink.
7218 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7219 glue() in SDCCglue.c creates an area for it.
7221 2002-09-03 Borut Razem <borut.razem AT siol.net>
7222 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7223 sdcc/src/pic/glue.c:
7224 introduced atexit() handler for teporay files removal in case of
7225 errors, assertions, ...
7227 2002-08-29 Borut Razem <borut.razem AT siol.net>
7228 * sdcc/support/cpp2/auto-host_vc_in.h:
7229 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7230 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7231 Maybe there is a similar problem with BORLANDC? It should be checked!
7233 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7234 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7235 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7236 was not executed, and the compiler (cl) launched a warning:
7237 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7239 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7240 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7242 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7243 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7245 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7246 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7247 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7248 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7249 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7250 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7251 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7252 - added Release configuration in VS projects
7253 - review of compiler an linker options
7254 - VC .exe files are generated in bin_vc directory, not to interfere
7255 with binaries generated from other projects (cygwin, mingw, bcc ...)
7257 * sdcc/src/yacc.dsp: added
7259 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7260 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7261 and insert the version number definitions from .version
7263 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7265 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7266 added - genarate auto-host.h using auto-host_vc_in.h as template
7269 removed from CVS, generated automatically
7271 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7272 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7274 2002-08-11 Borut Razem <borut.razem AT siol.net>
7275 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7277 2002-08-10 Borut Razem <borut.razem AT siol.net>
7278 * src/SDCCmain.c (main):
7279 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7280 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7281 The consequence was that some temporary files were not removed.
7284 unification of code in functions tempfilename() and tempfile():
7285 function tempnam() is defined in Visual Studio 6.0 and .NET
7287 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7289 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7290 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7291 - removed compiler command line option /WX: Treats all warnings as errors
7292 - update a list of source files, included into the project
7294 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7295 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7296 changed project type to Generic Project so that can be correcly converted to VS.NET project
7298 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7300 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7302 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7304 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7305 added return 0 statements after assert() to make compiler happy
7307 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7308 added newline in the def file to keep MSC compiler satisfied
7310 * sdcc/src/z80/gen.c:
7311 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7312 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7313 - solved MSC error in function aopDump()
7315 * sdcc_vc.h: define PREFIX as "\\sdcc"
7317 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7318 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7320 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7321 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7322 - Rewrote the register banking algorithm.
7323 - Added pCode live-range analysis to registers (for now, only non-used and
7324 singly-used registers optimized away)
7326 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7328 * 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.

7357 2002-03-28 Johan Knol <johan AT balder>
7359 * src/SDCCval.c: fixed bug #532436
7361 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7363 Added "char *Processor" field to the port structure.
7366 Added -p option. Allows port dependent processor to be specified.
7369 Initialized the new field char *Processor field to NULL in all ports
7372 Compiler generated registers for interrupt context saving
7373 were not getting allocated.
7375 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7378 Fixed left shift. Will promote the left side of a left shift
7379 if a) left shifting more than size of operand or b) when assigned
7380 to something size > size of left side
7382 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7384 tons of changes. Register allocation has been
7385 rewritten. Added customization for the various PICs. Flow
7386 analysis is restructured. ...
7392 Added. device.c is a PIC port hack to accomodate variations

7492 * sdcc/src/SDCCloop.c:
7493 Previous fix was not good. basic blocks that have "break" or "return" are
7494 not really partof a loop , but live ranges used in these blocks should
7495 be live thru the entire loop, so set partOfLoop but don't add them to
