9 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
11 * device/include/stdint.h: added
12 * device/lib/abs.c: added
13 * device/lib/labs.c: added
14 * device/include/stdlib.h: added abs() and labs() prototypes
15 * device/lib/libsdcc.lib: added abs and labs
16 * device/include/float.h,
17 * device/lib/_fsmul.c,
18 * device/lib/printf_fast.c,
19 * device/lib/printf_tiny.c: updated comments
21 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
23 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
26 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
28 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
29 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
31 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
33 * device/lib/printf_large.c: removed inline assembly for portability and
34 readability. Use printf_fast if speed or size are more important.
35 * src/pic16/gen.c: removed conditions around use of DEBUGpc
36 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
38 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
40 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
41 prevent compiler warning
43 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
45 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
46 moved to level 0 and declared as static. Also they are explicit
47 placed in access bank. This was necessery because some times they
48 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
49 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
50 optimizations. Currently only compare to unsigned char is implemented,
51 * src/pic16/gen.c: added fReturnIdx array,
52 * (struct resolvedIfx) is moved to gen.h and made public,
53 * (struct _G): added sregsAlloc and sregsAllocSet fields,
54 * (aopForSym): added an optimization to directly store in stack of
55 the operand of a SEND iCode,
56 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
57 but as registers instead (AOP_REG) using the fReturnIdx array,
58 * (pic16_freeAsmop): remove the freed register from the
60 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
62 * (pic16_popGetTempRegCond): changed function prototype, now
63 function takes also a bitVector argument v which holds the current
64 set of registers that are allocated for stack access by aopForSym,
65 registers allocated in aopForSym for accessing stack symbols are not
66 any more part of the functions usedRegs field,
67 * (genCall): some times aopOp is called for a stack variable to be
68 send, aopForSym might perform the push, if this is true make sure
69 that genCall doesn't push the variable twice by testing _G.resDirect,
70 * (genFunction): changed testing for unspecified interrupt number
71 from 256 to INTNO_UNSPEC,
72 * modified selection scheme of frame pointer generation. Previously
73 if function did use local registers a frame pointer was generated,
74 now a frame pointer is generated only if function has arguments
75 (that need PLUSW2 register access), or has stack arguments, or the
76 compiler is not instructed to omit the frame pointer,
77 * (genEndFunction): before restoring local registers that were saved
78 in the function preamble, also restore the registers that *might*
79 have been allocated for stack access,
80 * (genRet): removed some old comments,
81 * (genCmp, the active (RN's) version): added a call to the
82 pic16_genCmp_special function to perform the compare with a more
83 robust and optimized way,
84 * (genInline): a feature has been added in inline code generation,
85 which allows a wildcard variable substitution when writing inline
86 assembly. Code is incomplete and experimental therefore undocumented,
87 * (genCast): changed order of aopOp for result and right to allow
88 aopForSym to directly load the result if possible,
89 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
90 perform an optimized compare on some selected special occasions,
91 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
92 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
93 generate an IVT any more,
94 * src/pic16/main.c (pic16_optionsTable): added command line option
96 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
97 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
99 * src/pic16/NOTES: Raphael Neider added in list of active developers
100 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
101 jumptable_end to prevent bug #,
102 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
103 inCond and outCond fields,
104 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
105 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
106 turn off register spilling,
107 * (packRegsForOneUse): synced with other ports' versions although it
108 is not used currently,
109 * (pic16_packRegisters): added an optimization while reading
110 structure bitfields, some registers may be saved (malloc code is
111 decreased by 80 bytes)
113 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
115 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
116 left is a bitfield, if yes, then don't optimize assignment. Perhaps
117 this can be optimized more?
119 2005-03-10 Raphael Neider <rneider AT web.de>
121 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
122 genNearPointerGet): (hopefully) fixed access to bitfields via
123 pointers (p->bitN = x; and x = p->bitN; failed)
125 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
127 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

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

3843 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3844 loaded with the linker search paths (-L arguments) and the libraries
3845 to be linked with the current source (-l arguments). Changes
3846 currently will affect only the pic16 port.
3847 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3848 include path the port specific paths and port specific libraries,
3849 * gplink command now contains the $3 argument,
3850 * src/pic16/device.h,
3851 * src/pic16/device.c,: structure PIC_device is made public and
3852 renamed to PIC16_device, the same for variable Pics which is renamed

3867 Documenting changes from previous commits.
3868 * configure.in (version 1.56),
3869 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3870 when generating output files to configure the pic16 library,
3871 but now I've commented it out, since gputils aren't installed in the
3872 SF compile farm, so library won't compile
3874 * device/lib/Makefile.in (version 1.56): initially I've added in
3875 target 'all' the prerequestive 'model-pic16' so it compiled the
3876 pic16 library, but now I've commented it out for the same reasons
3878 * added targets 'model-pic16' and 'objects-pic16' to compile the
3880 * added target 'port-specific-objects-pic16' to handle the
3881 generated libraries and copy them into the build/ directory
3882 * added target 'clean-intermediate-pic16' to clean intermediate
3883 files into pic16 directory
3884 * in target 'installdirs' added line to create directory pic16 in

3906 option so that it actually works. Made it specific to the z80, since
3907 the gbz80 doesn't have these kinds of I/O ports.
3909 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4133 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4135 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4136 (default behaviour).
4138 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4140 A python script to validate compiler diagnostic messages. It can be
4141 used to verify that sdcc complains about bad c source code and
4142 gives a good location of the error.
4143 * support/valdiag/Makefile,
4144 * support/valdiag/valdiag.py,
4145 * support/valdiag/tests/*
4147 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4162 Bug reported from Jesus Calvino-Fraga
4164 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4166 * sdcc.spec: updated
4167 * device/include/Makefile.in: don't install CVS directories
4168 * device/lib/Makefile.in: added removal of CVS directories after install
4169 * doc/Makefile: fixed install, added local_icons
4170 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4171 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4172 * src/ds390/gen.c (genRightShift): fixed bug #870788

4175 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4177 PIC16 port related changes:
4178 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4179 added variable stackPos,
4181 * gen.c: genCall, assignResultValue: added support for
4182 pushing/retrieving function parameters to/from stack,
4183 genFunction,genEndFunction: setup stack frame for the
4185 genAddrOf: will be changed according to bug 863624
4187 * added files genutils.c and genutils.h which contain gen*
4188 debugged and optimised functions extracted from gen.c
4190 * glue.c: added variable 'externs' which holds extern symbols,
4191 pic16emitRegularMap: is modified to properly handle relocatable
4192 symbols under the new scheme,
4193 pic16createInterruptVect: is modified
4194 pic16printPublics: is modified to emit 'global' assembler directives,
4195 added pic16_printExterns to print extern symbols,
4196 pic16glue: initializes stack/frame pointer in the beginning of
4197 the assembly output. Temporary hack, will be corrected later,
4198 because gplink yet does not support stack and SDCC does not
4199 yet support a type of crt0.o object to create the final binary.
4201 * Removed many lines that contain 8051 legacy code.
4202 * The code is finally placed under a 'code' directive.
4203 * Added port specific options.
4205 * _process_pragma: simplified since now we do not need *special*
4206 include file to define SFR registers. But a separate header
4207 will be needed. This will be developed later.
4208 * _pic16_parseOptions: added, parses port specific options:
4209 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4210 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4211 --preplace-udata-with=
4213 * _pic16_setDefaultOptions: modified to initialize section names,
4214 but hack is temporarly out of order since it needs improvement.
4215 * _pic16_genAssemblerPreamble: configuration words are emitted by
4216 their address instead of their name. This part is incomplete and
4217 supports only the 18Fxx2 devices. Other devices will emit an error
4218 during assembly since they do not contain the same set of config
4220 * _pic16_genIVT: is modified,
4222 * pcode.c: added definitions for some hardware registers that are needed
4224 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4225 All PCI entries are updated. Now LFSR is supported.
4226 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4227 * added pic16_newpCodeOpLit2 to support instructions with
4228 two literal arguments
4229 * pic16_pCode2str: corrected code that emits assembler instructions
4230 with two literal operands and those that have an access bit modifier
4231 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4232 this fixes a bug which caused some labels to be lost, when an
4233 assembler directive was added, i.e. banksel,
4234 * pic16_FixRegisterBanking: improved logic that causes the insertion
4236 * InlineFunction: functions that are called once, are not any more
4237 inlined. This can be a port option in the future,
4239 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4241 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4242 hold the corresponding uninitialized symbols,
4243 * pic16_allocProcessorRegister: registers have explicit marked the
4245 * pic16_allocInternalRegister: registers are explicit marked as
4247 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4248 processing list, so bit registers were lost,
4251 * ralloc.h: added field 'accessBank' and original symbol operand
4252 in register definition,
4253 * removed the field isMapped from register definition,
4255 ** Several functions have been removed from various sources:
4256 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4257 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4258 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4259 pic16_assignRelocatableRegisters
4261 ** others have been introduced:
4262 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4263 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4265 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4267 * support/scripts/inc2h.pl: changed definition of BIT_AT
4268 to emit 'sbit at' instead of 'bit at'. This was a request.
4270 PIC16 port related preliminary changes:
4271 * gen.c: prefixed function popRegFromString with
4272 pic16_ and all references to it corrected
4273 * pcode.c: all pic16_pc_* hardware registers prefixed
4274 with underscore (_),
4275 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4276 * ralloc.c: newReg(): when register is REG_SFR then
4277 set address to rIdx,
4278 pic16_allocProcessorRegister(): marks register wasUsed=0
4279 pic16_writeUsedRegs(): added a call to assign processor
4280 registers via pic16_assignFixedRegisters
4282 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4284 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4285 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4286 variables in unused register banks. Also the SSEG is placed
4287 wherever there is enough space for it, and IDATA can be anywhere
4288 in internal RAM. For now compile using -Wl-Y[stack_size].
4289 The mem file is different for this option as well, since it
4290 makes no sense of talking about DSEG lenght.
4292 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4294 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4295 in certain cases, e.g. when ROM assignment, patch provided
4296 from Albert den Haan.

5300 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5301 fetching of the pointer
5302 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5303 copied from genNearPointerSet()
5304 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5305 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5306 If they pop r0/r1 they must be called in the opposite order than aopOp().
5307 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5308 (resp. --stack-auto), prepared for --xstack

5319 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5321 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5322 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5323 type for bits was changed. It resulted in bit variables becoming
5324 global, which is not permitted in PIC 14 assembly output.
5326 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5328 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5341 A few small changes that speed up the peephole optimizer.
5345 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5347 Try to make the peephole optimizer smarter by maintaining
5348 an association between the assembly source code and the
5349 iCodes that originated them. Put this information to use
5350 with a new peephole rule condition "notVolatile" so that
5351 the rules can be aggressive yet still safe.
5356 * src/mcs51/peeph.def
5358 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5362 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5363 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5364 if the left or right operand symbols have the accuse flag set.
5366 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5368 Changed the type of the result of the ! (NOT) operator to char;
5369 previously it returned the same type as the source. This allows
5370 us to eliminate all the genFloatNot functions (all of its target
5371 implementations were very buggy) since !float can use the same
5374 * src/SDCCicode.c (ast2iCode): ! returns char

5381 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5383 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5384 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5385 during interrupts. Ensure WSAVE is located at a shared bank address.
5386 2. Fixed page selection in some places
5387 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5388 the registers name strings.
5389 4. Fixed "signed / unsigned compare" compiler warnings.
5390 5. The PIC port manages its own allocation of the general purpose
5391 registers, but makes no attempt to reuse them. As a result when
5392 compiling it soon runs out of general purpose registers. Some
5393 additional code was added to the files pcode.c and device.c to walk
5394 through the function call tree and rename the registers so that they
5404 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5405 genPlus() & genMinus() when the result is the same as left or right

5411 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5413 Made bitfield a distinct type from bit so that bitfields
5414 convert as per ANSI C and bits retain their traditional
5415 boolean style behaviour. Implemented bitfield support in
5423 * src/ds390/gen.c: bit v bitfield split
5424 * src/z80/gen.c: New support for bitfields
5425 * support/regression/tests/bitfields.c: reenabled z80,
5428 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5430 Rules 246.x, 247.x relate to bitfields, the others speed up
5431 access to xdata mapped I/O devices.
5433 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5435 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5437 Cleaned up genPackBits and genUnpackBits and added two helper
5438 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5439 for literal assignments in genPackBits (thanks to Frieder for
5445 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5447 Fixed bug #748310 (pointer to function type mishandled when the
5448 function name is omitted). Also fixed a SIGSEGV when a function
5449 attribute (reentrant, etc) is used on a non-function or on a
5450 function but misplaced before the parameter list.
5452 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5454 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5455 * support/Util/SDCCerr.h,
5456 * support/Util/SDCCerr.c: Added func attr misuse error msg

5477 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5479 Made the constant following the "interrupt" keyword optional. If
5480 omitted, the function will not automatically be given an entry
5481 in the interrupt vector table (similar to #pragma NOIV, but
5482 less syntacticly kludgy). The interrupt number is also now
5483 range checked. Also fixed a bug in the high order bit example

5497 * src/SDCCicode.c (operandOperation): rewritten some ops
5498 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5499 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5501 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5502 be re-activated by defining REDUCE_LITERALS)
5503 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5504 unsigned, but are signed by default
5505 * src/SDCCval.c (constVal): rearranged
5506 * src/SDCCval.c (valMod): preliminary fix
5507 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5549 constants are unsigned; added recognition of "u" flag for unsigned
5550 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5551 * src/SDCCval.c (valDiv, valMod): fixed signdness

6013 added if/endif conditional macros to remove options help
6014 messages from optionsTable when a port is not configured, added
6015 support for the PIc16 port in the ports table, when executing
6016 the compiler with no port specified on command line, a default
6017 port is selected with the new macro DEFAULT_PORT which is
6018 defined in port.h, in setDefaultOptions() linkOptions is removed
6019 from initialization assignment, since now it is a set,
6020 parseCmdLine uses setParseWithComma for linkOptions, in
6021 linkEdit() linkOptions are accessed with new function indexSet()
6022 which returns the i'th item of a set variable. See SDCCset.c, in
6023 linkEdit() when calling buildCmdLine(), added linkOptions as
6024 last argument. Now users can pass arguments to gplink via the
6025 -Wl option, main() uses pic16glue() to glue up pic16 programs

6039 gpasm complaining and test the linkage with gplink, _linkCmd and
6040 _asmCmd changed to be more gplink and gpasm friendly
6041 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6042 produced an error when parsed, peep rule 12 is added to utilize
6043 movff, but it is commented out since the pCode does not support
6044 yet a command with 2 address arguments
6046 2003-05-18 <johan AT balder>
6048 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6073 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6075 2003-05-11 Borut Razem <borut.razem AT siol.net>
6077 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6078 the path of bin directory, so that PATH is the only env. variable, which has to be set

7087 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7089 2003-01-04 <johan AT balder>
7091 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7093 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7094 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o

7106 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7107 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7109 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7111 * in \sdcc\as\mcs51\ changed these files in order to create an
7112 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7113 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7114 following files to include the previous two files: aslink.dsp,
7115 Makefile.aslink, Makefile.bcc, and Makefile.in.
7117 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7118 .adb instead of .cdb
7120 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7122 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7123 value from option --iram-size.
7125 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7127 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7130 2002-09-18 <wiml AT hhhh.org>
7132 * SDCClrange.h: exposed setFromRange() and setToRange()
7133 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7134 packRegsForAccUse() (bug 542397)
7135 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7136 multiple times and emitting the fetch operations more than once
7137 added aopGetUsesAcc() function to allow binary operators to
7138 fetch their operands in the correct order; made genMinus() emit
7139 compact code for X = LITERAL - Y
7141 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7142 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7143 sprintf() in line 1267.
7145 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7146 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7149 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7150 Changes to aslink (All the changes are marked with 'JCF'):
7152 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7155 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7156 area BSEG. Also moves, if possible, the DATA area down into the internal
7157 ram so more space is available.
7159 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7162 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7163 not bytes. Function summary() which creates a memory usage summary
7164 file with extension .mem. Reports of overlaping stack and small stack
7165 size. If the space for the stack is less than 16 bytes aslink trows a
7168 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7169 the 8051. Option 'y' for memory summary output file.
7171 Changes to sdcc (All the changes are marked with 'JCF'):
7173 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7175 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7176 overlaying area for it (uses RegBankUsed[4]).
7178 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7179 bank zero as used by default. By default aslink locates the stack
7180 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7181 the creation of the .mem file. Delegates the allocation of data area
7182 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7183 the begining of the stack area to aslink.
7185 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7186 glue() in SDCCglue.c creates an area for it.
7188 2002-09-03 Borut Razem <borut.razem AT siol.net>
7189 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7190 sdcc/src/pic/glue.c:
7191 introduced atexit() handler for teporay files removal in case of
7192 errors, assertions, ...
7194 2002-08-29 Borut Razem <borut.razem AT siol.net>
7195 * sdcc/support/cpp2/auto-host_vc_in.h:
7196 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7197 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7198 Maybe there is a similar problem with BORLANDC? It should be checked!
7200 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7201 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7202 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7203 was not executed, and the compiler (cl) launched a warning:
7204 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7206 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7207 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7209 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7210 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7212 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7213 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7214 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7215 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7216 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7217 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7218 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7219 - added Release configuration in VS projects
7220 - review of compiler an linker options
7221 - VC .exe files are generated in bin_vc directory, not to interfere
7222 with binaries generated from other projects (cygwin, mingw, bcc ...)
7224 * sdcc/src/yacc.dsp: added
7226 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7227 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7228 and insert the version number definitions from .version
7230 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7232 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7233 added - genarate auto-host.h using auto-host_vc_in.h as template
7236 removed from CVS, generated automatically
7238 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7239 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7241 2002-08-11 Borut Razem <borut.razem AT siol.net>
7242 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7244 2002-08-10 Borut Razem <borut.razem AT siol.net>
7245 * src/SDCCmain.c (main):
7246 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7247 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7248 The consequence was that some temporary files were not removed.
7251 unification of code in functions tempfilename() and tempfile():
7252 function tempnam() is defined in Visual Studio 6.0 and .NET
7254 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7256 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7257 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7258 - removed compiler command line option /WX: Treats all warnings as errors
7259 - update a list of source files, included into the project
7261 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7262 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7263 changed project type to Generic Project so that can be correcly converted to VS.NET project
7265 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7267 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7269 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7271 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7272 added return 0 statements after assert() to make compiler happy
7274 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7275 added newline in the def file to keep MSC compiler satisfied
7277 * sdcc/src/z80/gen.c:
7278 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7279 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7280 - solved MSC error in function aopDump()
7282 * sdcc_vc.h: define PREFIX as "\\sdcc"
7284 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7285 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7288 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7289 - Rewrote the register banking algorithm.
7290 - Added pCode live-range analysis to registers (for now, only non-used and
7291 singly-used registers optimized away)
7293 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7295 * 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.

7324 2002-03-28 Johan Knol <johan AT balder>
7326 * src/SDCCval.c: fixed bug #532436
7328 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7330 Added "char *Processor" field to the port structure.
7333 Added -p option. Allows port dependent processor to be specified.
7336 Initialized the new field char *Processor field to NULL in all ports
7339 Compiler generated registers for interrupt context saving
7340 were not getting allocated.
7342 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7345 Fixed left shift. Will promote the left side of a left shift
7346 if a) left shifting more than size of operand or b) when assigned
7347 to something size > size of left side
7349 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7351 tons of changes. Register allocation has been
7352 rewritten. Added customization for the various PICs. Flow
7353 analysis is restructured. ...
7359 Added. device.c is a PIC port hack to accomodate variations
7362 2002-03-13 Michael Hope <michaelh AT vroom>
7364 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

7461 not really partof a loop , but live ranges used in these blocks should
7462 be live thru the entire loop, so set partOfLoop but don't add them to
