3 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4 prevent compiler warning
6 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
8 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
9 moved to level 0 and declared as static. Also they are explicit
10 placed in access bank. This was necessery because some times they
11 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
12 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
13 optimizations. Currently only compare to unsigned char is implemented,
14 * src/pic16/gen.c: added fReturnIdx array,
15 * (struct resolvedIfx) is moved to gen.h and made public,
16 * (struct _G): added sregsAlloc and sregsAllocSet fields,
17 * (aopForSym): added an optimization to directly store in stack of
18 the operand of a SEND iCode,
19 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
20 but as registers instead (AOP_REG) using the fReturnIdx array,
21 * (pic16_freeAsmop): remove the freed register from the
23 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
25 * (pic16_popGetTempRegCond): changed function prototype, now
26 function takes also a bitVector argument v which holds the current
27 set of registers that are allocated for stack access by aopForSym,
28 registers allocated in aopForSym for accessing stack symbols are not
29 any more part of the functions usedRegs field,
30 * (genCall): some times aopOp is called for a stack variable to be
31 send, aopForSym might perform the push, if this is true make sure
32 that genCall doesn't push the variable twice by testing _G.resDirect,
33 * (genFunction): changed testing for unspecified interrupt number
34 from 256 to INTNO_UNSPEC,
35 * modified selection scheme of frame pointer generation. Previously
36 if function did use local registers a frame pointer was generated,
37 now a frame pointer is generated only if function has arguments
38 (that need PLUSW2 register access), or has stack arguments, or the
39 compiler is not instructed to omit the frame pointer,
40 * (genEndFunction): before restoring local registers that were saved
41 in the function preamble, also restore the registers that *might*
42 have been allocated for stack access,
43 * (genRet): removed some old comments,
44 * (genCmp, the active (RN's) version): added a call to the
45 pic16_genCmp_special function to perform the compare with a more
46 robust and optimized way,
47 * (genInline): a feature has been added in inline code generation,
48 which allows a wildcard variable substitution when writing inline
49 assembly. Code is incomplete and experimental therefore undocumented,
50 * (genCast): changed order of aopOp for result and right to allow
51 aopForSym to directly load the result if possible,
52 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
53 perform an optimized compare on some selected special occasions,
54 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
55 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
56 generate an IVT any more,
57 * src/pic16/main.c (pic16_optionsTable): added command line option
59 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
60 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
62 * src/pic16/NOTES: Raphael Neider added in list of active developers
63 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
64 jumptable_end to prevent bug #,
65 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
66 inCond and outCond fields,
67 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
68 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
69 turn off register spilling,
70 * (packRegsForOneUse): synced with other ports' versions although it
71 is not used currently,
72 * (pic16_packRegisters): added an optimization while reading
73 structure bitfields, some registers may be saved (malloc code is
74 decreased by 80 bytes)
76 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
78 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
79 left is a bitfield, if yes, then don't optimize assignment. Perhaps
80 this can be optimized more?
82 2005-03-10 Raphael Neider <rneider AT web.de>
84 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
85 genNearPointerGet): (hopefully) fixed access to bitfields via
86 pointers (p->bitN = x; and x = p->bitN; failed)
88 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
90 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

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

3807 loaded with the linker search paths (-L arguments) and the libraries
3808 to be linked with the current source (-l arguments). Changes
3809 currently will affect only the pic16 port.
3810 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3811 include path the port specific paths and port specific libraries,
3812 * gplink command now contains the $3 argument,
3813 * src/pic16/device.h,
3814 * src/pic16/device.c,: structure PIC_device is made public and
3815 renamed to PIC16_device, the same for variable Pics which is renamed

3830 Documenting changes from previous commits.
3831 * configure.in (version 1.56),
3832 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3833 when generating output files to configure the pic16 library,
3834 but now I've commented it out, since gputils aren't installed in the
3835 SF compile farm, so library won't compile
3837 * device/lib/Makefile.in (version 1.56): initially I've added in
3838 target 'all' the prerequestive 'model-pic16' so it compiled the
3839 pic16 library, but now I've commented it out for the same reasons
3841 * added targets 'model-pic16' and 'objects-pic16' to compile the
3843 * added target 'port-specific-objects-pic16' to handle the
3844 generated libraries and copy them into the build/ directory
3845 * added target 'clean-intermediate-pic16' to clean intermediate
3846 files into pic16 directory
3847 * in target 'installdirs' added line to create directory pic16 in

4092 * src/SDCCast.c (decorateType),
4093 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
4094 LEFT_OP (left shift)
4096 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4098 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4099 (default behaviour).
4101 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4103 A python script to validate compiler diagnostic messages. It can be
4104 used to verify that sdcc complains about bad c source code and
4105 gives a good location of the error.
4106 * support/valdiag/Makefile,
4107 * support/valdiag/valdiag.py,
4108 * support/valdiag/tests/*
4110 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4125 Bug reported from Jesus Calvino-Fraga
4127 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4129 * sdcc.spec: updated
4130 * device/include/Makefile.in: don't install CVS directories
4131 * device/lib/Makefile.in: added removal of CVS directories after install
4132 * doc/Makefile: fixed install, added local_icons
4133 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4134 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4135 * src/ds390/gen.c (genRightShift): fixed bug #870788

4138 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4140 PIC16 port related changes:
4141 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4142 added variable stackPos,
4144 * gen.c: genCall, assignResultValue: added support for
4145 pushing/retrieving function parameters to/from stack,
4146 genFunction,genEndFunction: setup stack frame for the
4148 genAddrOf: will be changed according to bug 863624
4150 * added files genutils.c and genutils.h which contain gen*
4151 debugged and optimised functions extracted from gen.c
4153 * glue.c: added variable 'externs' which holds extern symbols,
4154 pic16emitRegularMap: is modified to properly handle relocatable
4155 symbols under the new scheme,
4156 pic16createInterruptVect: is modified
4157 pic16printPublics: is modified to emit 'global' assembler directives,
4158 added pic16_printExterns to print extern symbols,
4159 pic16glue: initializes stack/frame pointer in the beginning of
4160 the assembly output. Temporary hack, will be corrected later,
4161 because gplink yet does not support stack and SDCC does not
4162 yet support a type of crt0.o object to create the final binary.
4164 * Removed many lines that contain 8051 legacy code.
4165 * The code is finally placed under a 'code' directive.
4166 * Added port specific options.
4168 * _process_pragma: simplified since now we do not need *special*
4169 include file to define SFR registers. But a separate header
4170 will be needed. This will be developed later.
4171 * _pic16_parseOptions: added, parses port specific options:
4172 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4173 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4174 --preplace-udata-with=
4176 * _pic16_setDefaultOptions: modified to initialize section names,
4177 but hack is temporarly out of order since it needs improvement.
4178 * _pic16_genAssemblerPreamble: configuration words are emitted by
4179 their address instead of their name. This part is incomplete and
4180 supports only the 18Fxx2 devices. Other devices will emit an error
4181 during assembly since they do not contain the same set of config
4183 * _pic16_genIVT: is modified,
4185 * pcode.c: added definitions for some hardware registers that are needed
4187 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4188 All PCI entries are updated. Now LFSR is supported.
4189 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4190 * added pic16_newpCodeOpLit2 to support instructions with
4191 two literal arguments
4192 * pic16_pCode2str: corrected code that emits assembler instructions
4193 with two literal operands and those that have an access bit modifier
4194 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4195 this fixes a bug which caused some labels to be lost, when an
4196 assembler directive was added, i.e. banksel,
4197 * pic16_FixRegisterBanking: improved logic that causes the insertion
4199 * InlineFunction: functions that are called once, are not any more
4200 inlined. This can be a port option in the future,
4202 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4204 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4205 hold the corresponding uninitialized symbols,
4206 * pic16_allocProcessorRegister: registers have explicit marked the
4208 * pic16_allocInternalRegister: registers are explicit marked as
4210 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4211 processing list, so bit registers were lost,
4214 * ralloc.h: added field 'accessBank' and original symbol operand
4215 in register definition,
4216 * removed the field isMapped from register definition,
4218 ** Several functions have been removed from various sources:
4219 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4220 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4221 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4222 pic16_assignRelocatableRegisters
4224 ** others have been introduced:
4225 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4226 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4228 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4230 * support/scripts/inc2h.pl: changed definition of BIT_AT
4231 to emit 'sbit at' instead of 'bit at'. This was a request.
4233 PIC16 port related preliminary changes:
4234 * gen.c: prefixed function popRegFromString with
4235 pic16_ and all references to it corrected
4236 * pcode.c: all pic16_pc_* hardware registers prefixed
4237 with underscore (_),
4238 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4239 * ralloc.c: newReg(): when register is REG_SFR then
4240 set address to rIdx,
4241 pic16_allocProcessorRegister(): marks register wasUsed=0
4242 pic16_writeUsedRegs(): added a call to assign processor
4243 registers via pic16_assignFixedRegisters
4245 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4247 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4248 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4249 variables in unused register banks. Also the SSEG is placed
4250 wherever there is enough space for it, and IDATA can be anywhere
4251 in internal RAM. For now compile using -Wl-Y[stack_size].
4252 The mem file is different for this option as well, since it
4253 makes no sense of talking about DSEG lenght.
4255 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4257 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4258 in certain cases, e.g. when ROM assignment, patch provided
4259 from Albert den Haan.
4261 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4500 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4502 * src/SDCCast.c (decorateType): disabled a transformation I added in
4503 revision 1.188 (access to fields of a structure at an absolute address);
4504 it breaks with bitfields, extern declarations, and gcse analysis.
4505 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4506 could be assigned through a pointer, so don't complain.
4507 * src/SDCCast.c (astErrors),
4509 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
4511 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

5263 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5264 fetching of the pointer
5265 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5266 copied from genNearPointerSet()
5267 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5268 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5284 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5285 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5286 type for bits was changed. It resulted in bit variables becoming
5287 global, which is not permitted in PIC 14 assembly output.

5304 A few small changes that speed up the peephole optimizer.
5308 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5310 Try to make the peephole optimizer smarter by maintaining
5311 an association between the assembly source code and the
5312 iCodes that originated them. Put this information to use
5313 with a new peephole rule condition "notVolatile" so that
5314 the rules can be aggressive yet still safe.
5319 * src/mcs51/peeph.def
5321 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5325 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5326 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5327 if the left or right operand symbols have the accuse flag set.
5329 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5331 Changed the type of the result of the ! (NOT) operator to char;
5332 previously it returned the same type as the source. This allows
5333 us to eliminate all the genFloatNot functions (all of its target
5334 implementations were very buggy) since !float can use the same
5337 * src/SDCCicode.c (ast2iCode): ! returns char

5346 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5347 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5348 during interrupts. Ensure WSAVE is located at a shared bank address.
5349 2. Fixed page selection in some places
5350 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5351 the registers name strings.
5352 4. Fixed "signed / unsigned compare" compiler warnings.
5353 5. The PIC port manages its own allocation of the general purpose
5354 registers, but makes no attempt to reuse them. As a result when
5355 compiling it soon runs out of general purpose registers. Some
5356 additional code was added to the files pcode.c and device.c to walk
5357 through the function call tree and rename the registers so that they
5367 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5368 genPlus() & genMinus() when the result is the same as left or right

5374 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5376 Made bitfield a distinct type from bit so that bitfields
5377 convert as per ANSI C and bits retain their traditional
5378 boolean style behaviour. Implemented bitfield support in
5386 * src/ds390/gen.c: bit v bitfield split
5387 * src/z80/gen.c: New support for bitfields
5388 * support/regression/tests/bitfields.c: reenabled z80,
5391 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5393 Rules 246.x, 247.x relate to bitfields, the others speed up
5394 access to xdata mapped I/O devices.
5396 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5398 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5400 Cleaned up genPackBits and genUnpackBits and added two helper
5401 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5402 for literal assignments in genPackBits (thanks to Frieder for
5408 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5410 Fixed bug #748310 (pointer to function type mishandled when the
5411 function name is omitted). Also fixed a SIGSEGV when a function
5412 attribute (reentrant, etc) is used on a non-function or on a
5413 function but misplaced before the parameter list.
5415 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5417 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5418 * support/Util/SDCCerr.h,

5440 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5442 Made the constant following the "interrupt" keyword optional. If
5443 omitted, the function will not automatically be given an entry
5444 in the interrupt vector table (similar to #pragma NOIV, but
5445 less syntacticly kludgy). The interrupt number is also now
5446 range checked. Also fixed a bug in the high order bit example

5512 constants are unsigned; added recognition of "u" flag for unsigned
5513 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5514 * src/SDCCval.c (valDiv, valMod): fixed signdness
5515 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed

5978 support for the PIc16 port in the ports table, when executing
5979 the compiler with no port specified on command line, a default
5980 port is selected with the new macro DEFAULT_PORT which is
5981 defined in port.h, in setDefaultOptions() linkOptions is removed
5982 from initialization assignment, since now it is a set,
5983 parseCmdLine uses setParseWithComma for linkOptions, in
5984 linkEdit() linkOptions are accessed with new function indexSet()
5985 which returns the i'th item of a set variable. See SDCCset.c, in
5986 linkEdit() when calling buildCmdLine(), added linkOptions as
5987 last argument. Now users can pass arguments to gplink via the
5988 -Wl option, main() uses pic16glue() to glue up pic16 programs

6002 gpasm complaining and test the linkage with gplink, _linkCmd and
6003 _asmCmd changed to be more gplink and gpasm friendly
6004 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6005 produced an error when parsed, peep rule 12 is added to utilize
6006 movff, but it is commented out since the pCode does not support
6007 yet a command with 2 address arguments
6009 2003-05-18 <johan AT balder>

7044 2003-01-06 <johan AT balder>
7046 * src/SDCCicode.c: fixed array add
7048 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7049 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7050 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7052 2003-01-04 <johan AT balder>
7054 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7056 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7057 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7059 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

7069 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7070 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7072 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7074 * in \sdcc\as\mcs51\ changed these files in order to create an
7075 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7076 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7077 following files to include the previous two files: aslink.dsp,
7078 Makefile.aslink, Makefile.bcc, and Makefile.in.
7080 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7081 .adb instead of .cdb
7083 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7085 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7086 value from option --iram-size.
7088 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7090 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7093 2002-09-18 <wiml AT hhhh.org>
7095 * SDCClrange.h: exposed setFromRange() and setToRange()
7096 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7097 packRegsForAccUse() (bug 542397)
7098 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7099 multiple times and emitting the fetch operations more than once
7100 added aopGetUsesAcc() function to allow binary operators to
7101 fetch their operands in the correct order; made genMinus() emit
7102 compact code for X = LITERAL - Y
7104 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7105 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7106 sprintf() in line 1267.
7108 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7109 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7112 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7113 Changes to aslink (All the changes are marked with 'JCF'):
7115 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7118 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7119 area BSEG. Also moves, if possible, the DATA area down into the internal
7120 ram so more space is available.
7122 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7125 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7126 not bytes. Function summary() which creates a memory usage summary
7127 file with extension .mem. Reports of overlaping stack and small stack
7128 size. If the space for the stack is less than 16 bytes aslink trows a
7131 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7132 the 8051. Option 'y' for memory summary output file.
7134 Changes to sdcc (All the changes are marked with 'JCF'):
7136 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7138 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7139 overlaying area for it (uses RegBankUsed[4]).
7141 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7142 bank zero as used by default. By default aslink locates the stack
7143 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7144 the creation of the .mem file. Delegates the allocation of data area
7145 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7146 the begining of the stack area to aslink.
7148 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7149 glue() in SDCCglue.c creates an area for it.
7151 2002-09-03 Borut Razem <borut.razem AT siol.net>
7152 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7153 sdcc/src/pic/glue.c:
7154 introduced atexit() handler for teporay files removal in case of
7155 errors, assertions, ...
7157 2002-08-29 Borut Razem <borut.razem AT siol.net>
7158 * sdcc/support/cpp2/auto-host_vc_in.h:
7159 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7160 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7161 Maybe there is a similar problem with BORLANDC? It should be checked!
7163 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7164 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7165 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7166 was not executed, and the compiler (cl) launched a warning:
7167 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7169 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7170 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7172 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7173 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7175 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7176 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7177 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7178 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7179 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7180 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7181 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7182 - added Release configuration in VS projects
7183 - review of compiler an linker options
7184 - VC .exe files are generated in bin_vc directory, not to interfere
7185 with binaries generated from other projects (cygwin, mingw, bcc ...)
7187 * sdcc/src/yacc.dsp: added
7189 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7190 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7191 and insert the version number definitions from .version
7193 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7195 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7196 added - genarate auto-host.h using auto-host_vc_in.h as template
7199 removed from CVS, generated automatically
7201 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7202 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7204 2002-08-11 Borut Razem <borut.razem AT siol.net>
7205 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7207 2002-08-10 Borut Razem <borut.razem AT siol.net>
7208 * src/SDCCmain.c (main):
7209 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7210 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7211 The consequence was that some temporary files were not removed.
7214 unification of code in functions tempfilename() and tempfile():
7215 function tempnam() is defined in Visual Studio 6.0 and .NET
7217 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7219 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7220 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7221 - removed compiler command line option /WX: Treats all warnings as errors
7222 - update a list of source files, included into the project
7224 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7225 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7226 changed project type to Generic Project so that can be correcly converted to VS.NET project
7228 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7230 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7232 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7234 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7235 added return 0 statements after assert() to make compiler happy
7237 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7238 added newline in the def file to keep MSC compiler satisfied
7240 * sdcc/src/z80/gen.c:
7241 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7242 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7243 - solved MSC error in function aopDump()
7245 * sdcc_vc.h: define PREFIX as "\\sdcc"
7247 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7248 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7251 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7252 - Rewrote the register banking algorithm.
7253 - Added pCode live-range analysis to registers (for now, only non-used and
7254 singly-used registers optimized away)
7256 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7258 * 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.

7283 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7285 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7287 2002-03-28 Johan Knol <johan AT balder>
7289 * src/SDCCval.c: fixed bug #532436
7291 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7293 Added "char *Processor" field to the port structure.
7296 Added -p option. Allows port dependent processor to be specified.
7299 Initialized the new field char *Processor field to NULL in all ports
7302 Compiler generated registers for interrupt context saving
7303 were not getting allocated.
7305 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7308 Fixed left shift. Will promote the left side of a left shift
7309 if a) left shifting more than size of operand or b) when assigned
7310 to something size > size of left side
7312 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7314 tons of changes. Register allocation has been
7315 rewritten. Added customization for the various PICs. Flow
7316 analysis is restructured. ...
7322 Added. device.c is a PIC port hack to accomodate variations
7325 2002-03-13 Michael Hope <michaelh AT vroom>
7327 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7329 2002-03-04 johanknol <johanknol AT manik>
7331 * /src/SDCCval.c: fixed
7333 const unsigned char arr[][2] = { { 0, 1 } };

7336 2002-03-04 bela <bela AT manik>
7338 * /device/include/mcs51reg.h:
7339 ds89c420 register definition update
7341 2002-03-03 <johan AT FRIJA>

7420 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7422 * sdcc/src/SDCCloop.c:
7423 Previous fix was not good. basic blocks that have "break" or "return" are
7424 not really partof a loop , but live ranges used in these blocks should
7425 be live thru the entire loop, so set partOfLoop but don't add them to
7428 2002-02-21 <johan AT FRIJA>
7430 * src/SDCCcse.c: fixed bug #514308
7432 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7435 Fixed BUG #519583. If a conditional block ended in a return/break
7436 statement inside a loop, it was not being considered part of the loop.
7438 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7440 2002-02-10 Karl Bongers <karl AT turbobit.com>
7443 Fixed up SDCDB debugger somewhat. Updated debugger/README
7444 with lots of comments and notes.
7446 * device/examples/test2.c:
7447 Fix bug, "red" variable not being initialized(compiler complained).
7449 * device/examples/Makefile, examples/test3.c:
7450 Add Makefile in device/examples folder, compiles test3.c
7451 for use as a multiple module SDCDB test case.
7453 * sim/ucsim/cmd.src/cmdset.cc:
7454 Took out debug printfs in ucsim "next" command.
7457 Karl and Johan start ucsim XA support. Most dissassembly working,
7458 about 75% emulation done(plenty of work remaining).
7460 * sim/ucsim/z80.src:
7461 Add Z80 support to ucsim, add test-ucz80 regression test,
7462 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
7463 Notice z80 compiler fails on examples/test3.c/crc code.
7465 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
