3 * device/lib/printf_large.c: removed inline assembly for portability and
4 readability. Use printf_fast if speed or size are more important.
5 * src/pic16/gen.c: removed conditions around use of DEBUGpc
6 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
8 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
10 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
11 prevent compiler warning
13 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
15 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
16 moved to level 0 and declared as static. Also they are explicit
17 placed in access bank. This was necessery because some times they
18 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
19 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
20 optimizations. Currently only compare to unsigned char is implemented,
21 * src/pic16/gen.c: added fReturnIdx array,
22 * (struct resolvedIfx) is moved to gen.h and made public,
23 * (struct _G): added sregsAlloc and sregsAllocSet fields,
24 * (aopForSym): added an optimization to directly store in stack of
25 the operand of a SEND iCode,
26 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
27 but as registers instead (AOP_REG) using the fReturnIdx array,
28 * (pic16_freeAsmop): remove the freed register from the
30 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
32 * (pic16_popGetTempRegCond): changed function prototype, now
33 function takes also a bitVector argument v which holds the current
34 set of registers that are allocated for stack access by aopForSym,
35 registers allocated in aopForSym for accessing stack symbols are not
36 any more part of the functions usedRegs field,
37 * (genCall): some times aopOp is called for a stack variable to be
38 send, aopForSym might perform the push, if this is true make sure
39 that genCall doesn't push the variable twice by testing _G.resDirect,
40 * (genFunction): changed testing for unspecified interrupt number
41 from 256 to INTNO_UNSPEC,
42 * modified selection scheme of frame pointer generation. Previously
43 if function did use local registers a frame pointer was generated,
44 now a frame pointer is generated only if function has arguments
45 (that need PLUSW2 register access), or has stack arguments, or the
46 compiler is not instructed to omit the frame pointer,
47 * (genEndFunction): before restoring local registers that were saved
48 in the function preamble, also restore the registers that *might*
49 have been allocated for stack access,
50 * (genRet): removed some old comments,
51 * (genCmp, the active (RN's) version): added a call to the
52 pic16_genCmp_special function to perform the compare with a more
53 robust and optimized way,
54 * (genInline): a feature has been added in inline code generation,
55 which allows a wildcard variable substitution when writing inline
56 assembly. Code is incomplete and experimental therefore undocumented,
57 * (genCast): changed order of aopOp for result and right to allow
58 aopForSym to directly load the result if possible,
59 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
60 perform an optimized compare on some selected special occasions,
61 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
62 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
63 generate an IVT any more,
64 * src/pic16/main.c (pic16_optionsTable): added command line option
66 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
67 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
69 * src/pic16/NOTES: Raphael Neider added in list of active developers
70 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
71 jumptable_end to prevent bug #,
72 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
73 inCond and outCond fields,
74 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
75 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
76 turn off register spilling,
77 * (packRegsForOneUse): synced with other ports' versions although it
78 is not used currently,
79 * (pic16_packRegisters): added an optimization while reading
80 structure bitfields, some registers may be saved (malloc code is
81 decreased by 80 bytes)
83 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
85 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
86 left is a bitfield, if yes, then don't optimize assignment. Perhaps
87 this can be optimized more?
89 2005-03-10 Raphael Neider <rneider AT web.de>
91 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
92 genNearPointerGet): (hopefully) fixed access to bitfields via
93 pointers (p->bitN = x; and x = p->bitN; failed)
95 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
97 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

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

3814 loaded with the linker search paths (-L arguments) and the libraries
3815 to be linked with the current source (-l arguments). Changes
3816 currently will affect only the pic16 port.
3817 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3818 include path the port specific paths and port specific libraries,
3819 * gplink command now contains the $3 argument,
3820 * src/pic16/device.h,
3821 * src/pic16/device.c,: structure PIC_device is made public and
3822 renamed to PIC16_device, the same for variable Pics which is renamed

3837 Documenting changes from previous commits.
3838 * configure.in (version 1.56),
3839 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3840 when generating output files to configure the pic16 library,
3841 but now I've commented it out, since gputils aren't installed in the
3842 SF compile farm, so library won't compile
3844 * device/lib/Makefile.in (version 1.56): initially I've added in
3845 target 'all' the prerequestive 'model-pic16' so it compiled the
3846 pic16 library, but now I've commented it out for the same reasons
3848 * added targets 'model-pic16' and 'objects-pic16' to compile the
3850 * added target 'port-specific-objects-pic16' to handle the
3851 generated libraries and copy them into the build/ directory
3852 * added target 'clean-intermediate-pic16' to clean intermediate
3853 files into pic16 directory
3854 * in target 'installdirs' added line to create directory pic16 in

4050 * src/z80/main.c: changed appropriately to configure
4051 needLinkerScript flag
4053 * src/pic16/gen.c (genAddrOf): fixed bug #863624
4054 * src/pic/glue.c: added variable udata_section_name to

4065 arguments via -W option
4066 * src/pic16/main.c: added $l in _asmCmd, changed extension for
4067 object file from '.rel' to '.o' in port->linker structure,
4068 changed size of fptr from 2 to 3 in port structure
4070 2004-01-07 Borut Razem <borut.razem AT siol.net>
4072 * support/scripts/sdcc.nsi: update PATH

4089 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4091 * as/mcs51/lkmain.c: Help about -Y option
4092 * as/mcs51/lkarea.c: Fixed gcc warnings
4094 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>

4098 * support/valdiag/tests/overflow.c: added
4099 * src/SDCCast.c (decorateType),
4100 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
4101 LEFT_OP (left shift)
4103 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4105 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4106 (default behaviour).
4108 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4110 A python script to validate compiler diagnostic messages. It can be
4111 used to verify that sdcc complains about bad c source code and
4112 gives a good location of the error.
4113 * support/valdiag/Makefile,
4114 * support/valdiag/valdiag.py,
4115 * support/valdiag/tests/*
4117 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4130 * src/common.h: added ifndef/define/endif macros
4131 around the header file.
4132 Bug reported from Jesus Calvino-Fraga
4134 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4136 * sdcc.spec: updated
4137 * device/include/Makefile.in: don't install CVS directories
4138 * device/lib/Makefile.in: added removal of CVS directories after install
4139 * doc/Makefile: fixed install, added local_icons
4140 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4141 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4142 * src/ds390/gen.c (genRightShift): fixed bug #870788
4143 * src/SDCCast.c (decorateType): fixed bug #870781
4145 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4147 PIC16 port related changes:
4148 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4149 added variable stackPos,
4151 * gen.c: genCall, assignResultValue: added support for
4152 pushing/retrieving function parameters to/from stack,
4153 genFunction,genEndFunction: setup stack frame for the
4155 genAddrOf: will be changed according to bug 863624
4157 * added files genutils.c and genutils.h which contain gen*
4158 debugged and optimised functions extracted from gen.c
4160 * glue.c: added variable 'externs' which holds extern symbols,
4161 pic16emitRegularMap: is modified to properly handle relocatable
4162 symbols under the new scheme,
4163 pic16createInterruptVect: is modified
4164 pic16printPublics: is modified to emit 'global' assembler directives,
4165 added pic16_printExterns to print extern symbols,
4166 pic16glue: initializes stack/frame pointer in the beginning of
4167 the assembly output. Temporary hack, will be corrected later,
4168 because gplink yet does not support stack and SDCC does not
4169 yet support a type of crt0.o object to create the final binary.
4171 * Removed many lines that contain 8051 legacy code.
4172 * The code is finally placed under a 'code' directive.
4173 * Added port specific options.
4175 * _process_pragma: simplified since now we do not need *special*
4176 include file to define SFR registers. But a separate header
4177 will be needed. This will be developed later.
4178 * _pic16_parseOptions: added, parses port specific options:
4179 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4180 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4181 --preplace-udata-with=
4183 * _pic16_setDefaultOptions: modified to initialize section names,
4184 but hack is temporarly out of order since it needs improvement.
4185 * _pic16_genAssemblerPreamble: configuration words are emitted by
4186 their address instead of their name. This part is incomplete and
4187 supports only the 18Fxx2 devices. Other devices will emit an error
4188 during assembly since they do not contain the same set of config
4190 * _pic16_genIVT: is modified,
4192 * pcode.c: added definitions for some hardware registers that are needed
4194 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4195 All PCI entries are updated. Now LFSR is supported.
4196 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4197 * added pic16_newpCodeOpLit2 to support instructions with
4198 two literal arguments
4199 * pic16_pCode2str: corrected code that emits assembler instructions
4200 with two literal operands and those that have an access bit modifier
4201 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4202 this fixes a bug which caused some labels to be lost, when an
4203 assembler directive was added, i.e. banksel,
4204 * pic16_FixRegisterBanking: improved logic that causes the insertion
4206 * InlineFunction: functions that are called once, are not any more
4207 inlined. This can be a port option in the future,
4209 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4211 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4212 hold the corresponding uninitialized symbols,
4213 * pic16_allocProcessorRegister: registers have explicit marked the
4215 * pic16_allocInternalRegister: registers are explicit marked as
4217 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4218 processing list, so bit registers were lost,
4221 * ralloc.h: added field 'accessBank' and original symbol operand
4222 in register definition,
4223 * removed the field isMapped from register definition,
4225 ** Several functions have been removed from various sources:
4226 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4227 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4228 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4229 pic16_assignRelocatableRegisters
4231 ** others have been introduced:
4232 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4233 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4235 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4237 * support/scripts/inc2h.pl: changed definition of BIT_AT
4238 to emit 'sbit at' instead of 'bit at'. This was a request.
4240 PIC16 port related preliminary changes:
4241 * gen.c: prefixed function popRegFromString with
4242 pic16_ and all references to it corrected
4243 * pcode.c: all pic16_pc_* hardware registers prefixed
4244 with underscore (_),
4245 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4246 * ralloc.c: newReg(): when register is REG_SFR then
4247 set address to rIdx,
4248 pic16_allocProcessorRegister(): marks register wasUsed=0
4249 pic16_writeUsedRegs(): added a call to assign processor
4250 registers via pic16_assignFixedRegisters
4252 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4254 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4255 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4256 variables in unused register banks. Also the SSEG is placed
4257 wherever there is enough space for it, and IDATA can be anywhere
4258 in internal RAM. For now compile using -Wl-Y[stack_size].
4259 The mem file is different for this option as well, since it
4260 makes no sense of talking about DSEG lenght.
4262 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4264 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4265 in certain cases, e.g. when ROM assignment, patch provided
4266 from Albert den Haan.
4268 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4507 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4509 * src/SDCCast.c (decorateType): disabled a transformation I added in
4510 revision 1.188 (access to fields of a structure at an absolute address);
4511 it breaks with bitfields, extern declarations, and gcse analysis.
4512 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4513 could be assigned through a pointer, so don't complain.

5153 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
5154 support for standard C idiom of memory mapped variables; for
5155 example, *((xdata int*)0x1234) = 1 is now internally equivalent
5156 to xdata int at 0x1234 tempvar = 1.
5157 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
5158 provided by Akiya ISHIDA

5174 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5176 Fixed bug #621531 (const & volatile confusion in the type chain).
5177 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

5270 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5271 fetching of the pointer
5272 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5273 copied from genNearPointerSet()
5274 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5275 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5276 If they pop r0/r1 they must be called in the opposite order than aopOp().
5277 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5278 (resp. --stack-auto), prepared for --xstack

5291 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5292 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5293 type for bits was changed. It resulted in bit variables becoming
5294 global, which is not permitted in PIC 14 assembly output.
5296 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

5311 A few small changes that speed up the peephole optimizer.
5315 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5317 Try to make the peephole optimizer smarter by maintaining
5318 an association between the assembly source code and the
5319 iCodes that originated them. Put this information to use
5320 with a new peephole rule condition "notVolatile" so that
5321 the rules can be aggressive yet still safe.
5326 * src/mcs51/peeph.def
5328 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5332 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5333 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5334 if the left or right operand symbols have the accuse flag set.
5336 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5338 Changed the type of the result of the ! (NOT) operator to char;
5339 previously it returned the same type as the source. This allows
5340 us to eliminate all the genFloatNot functions (all of its target
5341 implementations were very buggy) since !float can use the same
5344 * src/SDCCicode.c (ast2iCode): ! returns char

5353 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5354 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5355 during interrupts. Ensure WSAVE is located at a shared bank address.
5356 2. Fixed page selection in some places
5357 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5358 the registers name strings.
5359 4. Fixed "signed / unsigned compare" compiler warnings.
5360 5. The PIC port manages its own allocation of the general purpose
5361 registers, but makes no attempt to reuse them. As a result when
5362 compiling it soon runs out of general purpose registers. Some
5363 additional code was added to the files pcode.c and device.c to walk
5364 through the function call tree and rename the registers so that they
5374 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5375 genPlus() & genMinus() when the result is the same as left or right

5381 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5383 Made bitfield a distinct type from bit so that bitfields
5384 convert as per ANSI C and bits retain their traditional
5385 boolean style behaviour. Implemented bitfield support in
5393 * src/ds390/gen.c: bit v bitfield split
5394 * src/z80/gen.c: New support for bitfields
5395 * support/regression/tests/bitfields.c: reenabled z80,
5398 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5400 Rules 246.x, 247.x relate to bitfields, the others speed up
5401 access to xdata mapped I/O devices.
5403 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5405 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5407 Cleaned up genPackBits and genUnpackBits and added two helper
5408 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5409 for literal assignments in genPackBits (thanks to Frieder for
5415 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5417 Fixed bug #748310 (pointer to function type mishandled when the
5418 function name is omitted). Also fixed a SIGSEGV when a function
5419 attribute (reentrant, etc) is used on a non-function or on a
5420 function but misplaced before the parameter list.
5422 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5424 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5425 * support/Util/SDCCerr.h,

5447 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5449 Made the constant following the "interrupt" keyword optional. If
5450 omitted, the function will not automatically be given an entry
5451 in the interrupt vector table (similar to #pragma NOIV, but
5452 less syntacticly kludgy). The interrupt number is also now
5453 range checked. Also fixed a bug in the high order bit example

5474 unsigned, but are signed by default
5475 * src/SDCCval.c (constVal): rearranged
5476 * src/SDCCval.c (valMod): preliminary fix
5477 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5519 constants are unsigned; added recognition of "u" flag for unsigned
5520 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5521 * src/SDCCval.c (valDiv, valMod): fixed signdness
5522 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed

5566 * support\librarian\configure.in
5567 * support\librarian\config_in.h

5983 added if/endif conditional macros to remove options help
5984 messages from optionsTable when a port is not configured, added
5985 support for the PIc16 port in the ports table, when executing
5986 the compiler with no port specified on command line, a default
5987 port is selected with the new macro DEFAULT_PORT which is
5988 defined in port.h, in setDefaultOptions() linkOptions is removed
5989 from initialization assignment, since now it is a set,
5990 parseCmdLine uses setParseWithComma for linkOptions, in
5991 linkEdit() linkOptions are accessed with new function indexSet()
5992 which returns the i'th item of a set variable. See SDCCset.c, in
5993 linkEdit() when calling buildCmdLine(), added linkOptions as
5994 last argument. Now users can pass arguments to gplink via the
5995 -Wl option, main() uses pic16glue() to glue up pic16 programs

6009 gpasm complaining and test the linkage with gplink, _linkCmd and
6010 _asmCmd changed to be more gplink and gpasm friendly
6011 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6012 produced an error when parsed, peep rule 12 is added to utilize
6013 movff, but it is commented out since the pCode does not support
6014 yet a command with 2 address arguments
6016 2003-05-18 <johan AT balder>
6018 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7036 2003-01-07 <johan AT balder>
7038 * src/SDCCast.c (decorateType): fixed bug #600035
7040 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>

7051 2003-01-06 <johan AT balder>
7053 * src/SDCCicode.c: fixed array add
7055 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7056 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7057 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7059 2003-01-04 <johan AT balder>
7061 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7063 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7064 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7066 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7067 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

7073 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7074 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7076 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7077 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7079 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7081 * in \sdcc\as\mcs51\ changed these files in order to create an
7082 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7083 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7084 following files to include the previous two files: aslink.dsp,
7085 Makefile.aslink, Makefile.bcc, and Makefile.in.
7087 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7088 .adb instead of .cdb
7090 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7092 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7093 value from option --iram-size.
7095 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7097 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7100 2002-09-18 <wiml AT hhhh.org>
7102 * SDCClrange.h: exposed setFromRange() and setToRange()
7103 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7104 packRegsForAccUse() (bug 542397)
7105 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7106 multiple times and emitting the fetch operations more than once
7107 added aopGetUsesAcc() function to allow binary operators to
7108 fetch their operands in the correct order; made genMinus() emit
7109 compact code for X = LITERAL - Y
7111 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7112 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7113 sprintf() in line 1267.
7115 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7116 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7119 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7120 Changes to aslink (All the changes are marked with 'JCF'):
7122 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7125 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7126 area BSEG. Also moves, if possible, the DATA area down into the internal
7127 ram so more space is available.
7129 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7132 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7133 not bytes. Function summary() which creates a memory usage summary
7134 file with extension .mem. Reports of overlaping stack and small stack
7135 size. If the space for the stack is less than 16 bytes aslink trows a
7138 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7139 the 8051. Option 'y' for memory summary output file.
7141 Changes to sdcc (All the changes are marked with 'JCF'):
7143 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7145 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7146 overlaying area for it (uses RegBankUsed[4]).
7148 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7149 bank zero as used by default. By default aslink locates the stack
7150 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7151 the creation of the .mem file. Delegates the allocation of data area
7152 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7153 the begining of the stack area to aslink.
7155 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7156 glue() in SDCCglue.c creates an area for it.
7158 2002-09-03 Borut Razem <borut.razem AT siol.net>
7159 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7160 sdcc/src/pic/glue.c:
7161 introduced atexit() handler for teporay files removal in case of
7162 errors, assertions, ...
7164 2002-08-29 Borut Razem <borut.razem AT siol.net>
7165 * sdcc/support/cpp2/auto-host_vc_in.h:
7166 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7167 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7168 Maybe there is a similar problem with BORLANDC? It should be checked!
7170 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7171 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7172 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7173 was not executed, and the compiler (cl) launched a warning:
7174 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7176 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7177 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7179 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7180 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7182 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7183 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7184 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7185 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7186 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7187 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7188 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7189 - added Release configuration in VS projects
7190 - review of compiler an linker options
7191 - VC .exe files are generated in bin_vc directory, not to interfere
7192 with binaries generated from other projects (cygwin, mingw, bcc ...)
7194 * sdcc/src/yacc.dsp: added
7196 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7197 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7198 and insert the version number definitions from .version
7200 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7202 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7203 added - genarate auto-host.h using auto-host_vc_in.h as template
7206 removed from CVS, generated automatically
7208 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7209 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7211 2002-08-11 Borut Razem <borut.razem AT siol.net>
7212 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7214 2002-08-10 Borut Razem <borut.razem AT siol.net>
7215 * src/SDCCmain.c (main):
7216 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7217 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7218 The consequence was that some temporary files were not removed.
7221 unification of code in functions tempfilename() and tempfile():
7222 function tempnam() is defined in Visual Studio 6.0 and .NET
7224 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7226 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7227 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7228 - removed compiler command line option /WX: Treats all warnings as errors
7229 - update a list of source files, included into the project
7231 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7232 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7233 changed project type to Generic Project so that can be correcly converted to VS.NET project
7235 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7237 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7239 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7241 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7242 added return 0 statements after assert() to make compiler happy
7244 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7245 added newline in the def file to keep MSC compiler satisfied
7247 * sdcc/src/z80/gen.c:
7248 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7249 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7250 - solved MSC error in function aopDump()
7252 * sdcc_vc.h: define PREFIX as "\\sdcc"
7254 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7255 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
7257 2002-06-22 Scott Dattalo <scott AT dattalo.com>
7258 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7259 - Rewrote the register banking algorithm.
7260 - Added pCode live-range analysis to registers (for now, only non-used and
7261 singly-used registers optimized away)
7263 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7265 * 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.
7267 2002-05-10 Scott Dattalo <scott AT dattalo.com>
7268 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
7270 2002-04-22 Michael Hope <michaelh AT vroom>

7290 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
7292 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
7294 2002-03-28 Johan Knol <johan AT balder>
7296 * src/SDCCval.c: fixed bug #532436
7298 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7300 Added "char *Processor" field to the port structure.
7303 Added -p option. Allows port dependent processor to be specified.
7306 Initialized the new field char *Processor field to NULL in all ports
7309 Compiler generated registers for interrupt context saving
7310 were not getting allocated.
7312 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7315 Fixed left shift. Will promote the left side of a left shift
7316 if a) left shifting more than size of operand or b) when assigned
7317 to something size > size of left side
7319 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7321 tons of changes. Register allocation has been
7322 rewritten. Added customization for the various PICs. Flow
7323 analysis is restructured. ...
7329 Added. device.c is a PIC port hack to accomodate variations
7332 2002-03-13 Michael Hope <michaelh AT vroom>
7334 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
7336 2002-03-04 johanknol <johanknol AT manik>
7338 * /src/SDCCval.c: fixed
7340 const unsigned char arr[][2] = { { 0, 1 } };
7341 t18.c:1: error: Initializer element is not constant
7343 2002-03-04 bela <bela AT manik>
7345 * /device/include/mcs51reg.h:
7346 ds89c420 register definition update
7348 2002-03-03 <johan AT FRIJA>

7427 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7429 * sdcc/src/SDCCloop.c:
7430 Previous fix was not good. basic blocks that have "break" or "return" are
7431 not really partof a loop , but live ranges used in these blocks should
7432 be live thru the entire loop, so set partOfLoop but don't add them to
7435 2002-02-21 <johan AT FRIJA>
7437 * src/SDCCcse.c: fixed bug #514308
7439 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7442 Fixed BUG #519583. If a conditional block ended in a return/break
7443 statement inside a loop, it was not being considered part of the loop.
7445 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7447 2002-02-10 Karl Bongers <karl AT turbobit.com>
7450 Fixed up SDCDB debugger somewhat. Updated debugger/README
7451 with lots of comments and notes.
7453 * device/examples/test2.c:
7454 Fix bug, "red" variable not being initialized(compiler complained).
