5 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
7 * device/include/stdint.h: added
8 * device/lib/abs.c: added
9 * device/lib/labs.c: added
10 * device/include/stdlib.h: added abs() and labs() prototypes
11 * device/lib/libsdcc.lib: added abs and labs
12 * device/include/float.h,
13 * device/lib/_fsmul.c,
14 * device/lib/printf_fast.c,
15 * device/lib/printf_tiny.c: updated comments
17 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
19 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
22 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
24 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
25 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
27 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
29 * device/lib/printf_large.c: removed inline assembly for portability and
30 readability. Use printf_fast if speed or size are more important.
31 * src/pic16/gen.c: removed conditions around use of DEBUGpc
32 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
34 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
36 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
37 prevent compiler warning
39 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
41 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
42 moved to level 0 and declared as static. Also they are explicit
43 placed in access bank. This was necessery because some times they
44 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
45 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
46 optimizations. Currently only compare to unsigned char is implemented,
47 * src/pic16/gen.c: added fReturnIdx array,
48 * (struct resolvedIfx) is moved to gen.h and made public,
49 * (struct _G): added sregsAlloc and sregsAllocSet fields,
50 * (aopForSym): added an optimization to directly store in stack of
51 the operand of a SEND iCode,
52 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
53 but as registers instead (AOP_REG) using the fReturnIdx array,
54 * (pic16_freeAsmop): remove the freed register from the
56 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
58 * (pic16_popGetTempRegCond): changed function prototype, now
59 function takes also a bitVector argument v which holds the current
60 set of registers that are allocated for stack access by aopForSym,
61 registers allocated in aopForSym for accessing stack symbols are not
62 any more part of the functions usedRegs field,
63 * (genCall): some times aopOp is called for a stack variable to be
64 send, aopForSym might perform the push, if this is true make sure
65 that genCall doesn't push the variable twice by testing _G.resDirect,
66 * (genFunction): changed testing for unspecified interrupt number
67 from 256 to INTNO_UNSPEC,
68 * modified selection scheme of frame pointer generation. Previously
69 if function did use local registers a frame pointer was generated,
70 now a frame pointer is generated only if function has arguments
71 (that need PLUSW2 register access), or has stack arguments, or the
72 compiler is not instructed to omit the frame pointer,
73 * (genEndFunction): before restoring local registers that were saved
74 in the function preamble, also restore the registers that *might*
75 have been allocated for stack access,
76 * (genRet): removed some old comments,
77 * (genCmp, the active (RN's) version): added a call to the
78 pic16_genCmp_special function to perform the compare with a more
79 robust and optimized way,
80 * (genInline): a feature has been added in inline code generation,
81 which allows a wildcard variable substitution when writing inline
82 assembly. Code is incomplete and experimental therefore undocumented,
83 * (genCast): changed order of aopOp for result and right to allow
84 aopForSym to directly load the result if possible,
85 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
86 perform an optimized compare on some selected special occasions,
87 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
88 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
89 generate an IVT any more,
90 * src/pic16/main.c (pic16_optionsTable): added command line option
92 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
93 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
95 * src/pic16/NOTES: Raphael Neider added in list of active developers
96 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
97 jumptable_end to prevent bug #,
98 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
99 inCond and outCond fields,
100 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
101 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
102 turn off register spilling,
103 * (packRegsForOneUse): synced with other ports' versions although it
104 is not used currently,
105 * (pic16_packRegisters): added an optimization while reading
106 structure bitfields, some registers may be saved (malloc code is
107 decreased by 80 bytes)
109 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
111 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
112 left is a bitfield, if yes, then don't optimize assignment. Perhaps
113 this can be optimized more?
115 2005-03-10 Raphael Neider <rneider AT web.de>
117 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
118 genNearPointerGet): (hopefully) fixed access to bitfields via
119 pointers (p->bitN = x; and x = p->bitN; failed)

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

3839 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
3840 loaded with the linker search paths (-L arguments) and the libraries
3841 to be linked with the current source (-l arguments). Changes
3842 currently will affect only the pic16 port.
3843 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
3844 include path the port specific paths and port specific libraries,
3845 * gplink command now contains the $3 argument,
3846 * src/pic16/device.h,
3847 * src/pic16/device.c,: structure PIC_device is made public and
3848 renamed to PIC16_device, the same for variable Pics which is renamed

3863 Documenting changes from previous commits.
3864 * configure.in (version 1.56),
3865 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
3866 when generating output files to configure the pic16 library,
3867 but now I've commented it out, since gputils aren't installed in the
3868 SF compile farm, so library won't compile
3870 * device/lib/Makefile.in (version 1.56): initially I've added in
3871 target 'all' the prerequestive 'model-pic16' so it compiled the
3872 pic16 library, but now I've commented it out for the same reasons
3874 * added targets 'model-pic16' and 'objects-pic16' to compile the
3876 * added target 'port-specific-objects-pic16' to handle the
3877 generated libraries and copy them into the build/ directory
3878 * added target 'clean-intermediate-pic16' to clean intermediate
3879 files into pic16 directory
3880 * in target 'installdirs' added line to create directory pic16 in

3934 data are now emitted in sorted order to reduce section naming,
3935 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
3936 weren't marked as being in the access bank,

4129 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4131 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
4132 (default behaviour).
4134 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4136 A python script to validate compiler diagnostic messages. It can be
4137 used to verify that sdcc complains about bad c source code and
4138 gives a good location of the error.
4139 * support/valdiag/Makefile,
4140 * support/valdiag/valdiag.py,
4141 * support/valdiag/tests/*

4158 Bug reported from Jesus Calvino-Fraga
4160 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
4162 * sdcc.spec: updated
4163 * device/include/Makefile.in: don't install CVS directories
4164 * device/lib/Makefile.in: added removal of CVS directories after install
4165 * doc/Makefile: fixed install, added local_icons
4166 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
4167 * src/mcs51/gen.c (genRightShift): fixed bug #870788
4168 * src/ds390/gen.c (genRightShift): fixed bug #870788
4169 * src/SDCCast.c (decorateType): fixed bug #870781
4171 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4173 PIC16 port related changes:
4174 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4175 added variable stackPos,
4177 * gen.c: genCall, assignResultValue: added support for
4178 pushing/retrieving function parameters to/from stack,
4179 genFunction,genEndFunction: setup stack frame for the
4181 genAddrOf: will be changed according to bug 863624
4183 * added files genutils.c and genutils.h which contain gen*
4184 debugged and optimised functions extracted from gen.c
4186 * glue.c: added variable 'externs' which holds extern symbols,
4187 pic16emitRegularMap: is modified to properly handle relocatable
4188 symbols under the new scheme,
4189 pic16createInterruptVect: is modified
4190 pic16printPublics: is modified to emit 'global' assembler directives,
4191 added pic16_printExterns to print extern symbols,
4192 pic16glue: initializes stack/frame pointer in the beginning of
4193 the assembly output. Temporary hack, will be corrected later,
4194 because gplink yet does not support stack and SDCC does not
4195 yet support a type of crt0.o object to create the final binary.
4197 * Removed many lines that contain 8051 legacy code.
4198 * The code is finally placed under a 'code' directive.
4199 * Added port specific options.
4201 * _process_pragma: simplified since now we do not need *special*
4202 include file to define SFR registers. But a separate header
4203 will be needed. This will be developed later.
4204 * _pic16_parseOptions: added, parses port specific options:
4205 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4206 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4207 --preplace-udata-with=
4209 * _pic16_setDefaultOptions: modified to initialize section names,
4210 but hack is temporarly out of order since it needs improvement.
4211 * _pic16_genAssemblerPreamble: configuration words are emitted by
4212 their address instead of their name. This part is incomplete and
4213 supports only the 18Fxx2 devices. Other devices will emit an error
4214 during assembly since they do not contain the same set of config
4216 * _pic16_genIVT: is modified,
4218 * pcode.c: added definitions for some hardware registers that are needed
4220 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4221 All PCI entries are updated. Now LFSR is supported.
4222 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4223 * added pic16_newpCodeOpLit2 to support instructions with
4224 two literal arguments
4225 * pic16_pCode2str: corrected code that emits assembler instructions
4226 with two literal operands and those that have an access bit modifier
4227 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4228 this fixes a bug which caused some labels to be lost, when an
4229 assembler directive was added, i.e. banksel,
4230 * pic16_FixRegisterBanking: improved logic that causes the insertion
4232 * InlineFunction: functions that are called once, are not any more
4233 inlined. This can be a port option in the future,
4235 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4237 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4238 hold the corresponding uninitialized symbols,
4239 * pic16_allocProcessorRegister: registers have explicit marked the
4241 * pic16_allocInternalRegister: registers are explicit marked as
4243 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4244 processing list, so bit registers were lost,
4247 * ralloc.h: added field 'accessBank' and original symbol operand
4248 in register definition,
4249 * removed the field isMapped from register definition,
4251 ** Several functions have been removed from various sources:
4252 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4253 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4254 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4255 pic16_assignRelocatableRegisters
4257 ** others have been introduced:
4258 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4259 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4261 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4263 * support/scripts/inc2h.pl: changed definition of BIT_AT
4264 to emit 'sbit at' instead of 'bit at'. This was a request.
4266 PIC16 port related preliminary changes:
4267 * gen.c: prefixed function popRegFromString with
4268 pic16_ and all references to it corrected
4269 * pcode.c: all pic16_pc_* hardware registers prefixed
4270 with underscore (_),
4271 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4272 * ralloc.c: newReg(): when register is REG_SFR then
4273 set address to rIdx,
4274 pic16_allocProcessorRegister(): marks register wasUsed=0
4275 pic16_writeUsedRegs(): added a call to assign processor
4276 registers via pic16_assignFixedRegisters
4278 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4280 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4281 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4282 variables in unused register banks. Also the SSEG is placed
4283 wherever there is enough space for it, and IDATA can be anywhere
4284 in internal RAM. For now compile using -Wl-Y[stack_size].
4285 The mem file is different for this option as well, since it
4286 makes no sense of talking about DSEG lenght.
4288 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4290 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4291 in certain cases, e.g. when ROM assignment, patch provided
4292 from Albert den Haan.
4294 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5296 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5297 fetching of the pointer
5298 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5299 copied from genNearPointerSet()
5300 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5301 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
5302 If they pop r0/r1 they must be called in the opposite order than aopOp().
5303 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
5304 (resp. --stack-auto), prepared for --xstack

5315 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
5317 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5318 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5319 type for bits was changed. It resulted in bit variables becoming
5320 global, which is not permitted in PIC 14 assembly output.
5322 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5324 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5337 A few small changes that speed up the peephole optimizer.
5341 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5343 Try to make the peephole optimizer smarter by maintaining
5344 an association between the assembly source code and the
5345 iCodes that originated them. Put this information to use
5346 with a new peephole rule condition "notVolatile" so that
5347 the rules can be aggressive yet still safe.
5352 * src/mcs51/peeph.def
5354 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5358 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5359 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5360 if the left or right operand symbols have the accuse flag set.
5362 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5364 Changed the type of the result of the ! (NOT) operator to char;
5365 previously it returned the same type as the source. This allows
5366 us to eliminate all the genFloatNot functions (all of its target
5367 implementations were very buggy) since !float can use the same
5370 * src/SDCCicode.c (ast2iCode): ! returns char
5371 * src/mcs51/gen.c (genNot, genNotFloat),
5372 * src/ds390/gen.c (genNot, genNotFloat),
5373 * src/z80/gen.c (genNot, genNotFloat),
5374 * src/pic/gen.c (genNot, genNotFloat),
5375 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
5377 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
5379 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5380 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5381 during interrupts. Ensure WSAVE is located at a shared bank address.
5382 2. Fixed page selection in some places
5383 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5384 the registers name strings.
5385 4. Fixed "signed / unsigned compare" compiler warnings.
5386 5. The PIC port manages its own allocation of the general purpose
5387 registers, but makes no attempt to reuse them. As a result when
5388 compiling it soon runs out of general purpose registers. Some
5389 additional code was added to the files pcode.c and device.c to walk
5390 through the function call tree and rename the registers so that they
5400 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5401 genPlus() & genMinus() when the result is the same as left or right
5403 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5407 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5409 Made bitfield a distinct type from bit so that bitfields
5410 convert as per ANSI C and bits retain their traditional
5411 boolean style behaviour. Implemented bitfield support in
5419 * src/ds390/gen.c: bit v bitfield split
5420 * src/z80/gen.c: New support for bitfields
5421 * support/regression/tests/bitfields.c: reenabled z80,
5424 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5426 Rules 246.x, 247.x relate to bitfields, the others speed up
5427 access to xdata mapped I/O devices.
5429 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5431 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5433 Cleaned up genPackBits and genUnpackBits and added two helper
5434 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5435 for literal assignments in genPackBits (thanks to Frieder for
5441 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5443 Fixed bug #748310 (pointer to function type mishandled when the
5444 function name is omitted). Also fixed a SIGSEGV when a function
5445 attribute (reentrant, etc) is used on a non-function or on a
5446 function but misplaced before the parameter list.
5448 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5450 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5451 * support/Util/SDCCerr.h,
5452 * support/Util/SDCCerr.c: Added func attr misuse error msg

5473 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5475 Made the constant following the "interrupt" keyword optional. If
5476 omitted, the function will not automatically be given an entry
5477 in the interrupt vector table (similar to #pragma NOIV, but
5478 less syntacticly kludgy). The interrupt number is also now
5479 range checked. Also fixed a bug in the high order bit example

5493 * src/SDCCicode.c (operandOperation): rewritten some ops
5494 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5495 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5497 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5498 be re-activated by defining REDUCE_LITERALS)
5499 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5500 unsigned, but are signed by default
5501 * src/SDCCval.c (constVal): rearranged
5502 * src/SDCCval.c (valMod): preliminary fix
5503 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6009 added if/endif conditional macros to remove options help
6010 messages from optionsTable when a port is not configured, added
6011 support for the PIc16 port in the ports table, when executing
6012 the compiler with no port specified on command line, a default
6013 port is selected with the new macro DEFAULT_PORT which is
6014 defined in port.h, in setDefaultOptions() linkOptions is removed
6015 from initialization assignment, since now it is a set,
6016 parseCmdLine uses setParseWithComma for linkOptions, in
6017 linkEdit() linkOptions are accessed with new function indexSet()
6018 which returns the i'th item of a set variable. See SDCCset.c, in
6019 linkEdit() when calling buildCmdLine(), added linkOptions as
6020 last argument. Now users can pass arguments to gplink via the
6021 -Wl option, main() uses pic16glue() to glue up pic16 programs

6035 gpasm complaining and test the linkage with gplink, _linkCmd and
6036 _asmCmd changed to be more gplink and gpasm friendly
6037 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6038 produced an error when parsed, peep rule 12 is added to utilize
6039 movff, but it is commented out since the pCode does not support
6040 yet a command with 2 address arguments
6042 2003-05-18 <johan AT balder>
6044 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6069 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
6071 2003-05-11 Borut Razem <borut.razem AT siol.net>
6073 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

7081 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
7082 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
7083 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
7085 2003-01-04 <johan AT balder>
7087 * src/SDCCval.c (getNelements): fixed the initialized array of structures
7089 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7090 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7092 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

7102 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7103 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7105 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7107 * in \sdcc\as\mcs51\ changed these files in order to create an
7108 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7109 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7110 following files to include the previous two files: aslink.dsp,
7111 Makefile.aslink, Makefile.bcc, and Makefile.in.
7113 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7114 .adb instead of .cdb
7116 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7118 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7119 value from option --iram-size.
7121 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7123 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7126 2002-09-18 <wiml AT hhhh.org>
7128 * SDCClrange.h: exposed setFromRange() and setToRange()
7129 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7130 packRegsForAccUse() (bug 542397)
7131 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7132 multiple times and emitting the fetch operations more than once
7133 added aopGetUsesAcc() function to allow binary operators to
7134 fetch their operands in the correct order; made genMinus() emit
7135 compact code for X = LITERAL - Y
7137 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7138 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7139 sprintf() in line 1267.
7141 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7142 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7145 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7146 Changes to aslink (All the changes are marked with 'JCF'):
7148 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7151 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7152 area BSEG. Also moves, if possible, the DATA area down into the internal
7153 ram so more space is available.
7155 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7158 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7159 not bytes. Function summary() which creates a memory usage summary
7160 file with extension .mem. Reports of overlaping stack and small stack
7161 size. If the space for the stack is less than 16 bytes aslink trows a
7164 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7165 the 8051. Option 'y' for memory summary output file.
7167 Changes to sdcc (All the changes are marked with 'JCF'):
7169 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7171 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7172 overlaying area for it (uses RegBankUsed[4]).
7174 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7175 bank zero as used by default. By default aslink locates the stack
7176 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7177 the creation of the .mem file. Delegates the allocation of data area
7178 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7179 the begining of the stack area to aslink.
7181 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7182 glue() in SDCCglue.c creates an area for it.
7184 2002-09-03 Borut Razem <borut.razem AT siol.net>
7185 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7186 sdcc/src/pic/glue.c:
7187 introduced atexit() handler for teporay files removal in case of
7188 errors, assertions, ...
7190 2002-08-29 Borut Razem <borut.razem AT siol.net>
7191 * sdcc/support/cpp2/auto-host_vc_in.h:
7192 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7193 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7194 Maybe there is a similar problem with BORLANDC? It should be checked!
7196 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7197 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7198 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7199 was not executed, and the compiler (cl) launched a warning:
7200 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7202 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7203 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7205 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7206 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7208 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7209 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7210 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7211 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7212 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7213 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7214 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7215 - added Release configuration in VS projects
7216 - review of compiler an linker options
7217 - VC .exe files are generated in bin_vc directory, not to interfere
7218 with binaries generated from other projects (cygwin, mingw, bcc ...)
7220 * sdcc/src/yacc.dsp: added
7222 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7223 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7224 and insert the version number definitions from .version
7226 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7228 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7229 added - genarate auto-host.h using auto-host_vc_in.h as template
7232 removed from CVS, generated automatically
7234 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7235 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7237 2002-08-11 Borut Razem <borut.razem AT siol.net>
7238 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7240 2002-08-10 Borut Razem <borut.razem AT siol.net>
7241 * src/SDCCmain.c (main):
7242 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7243 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7244 The consequence was that some temporary files were not removed.
7247 unification of code in functions tempfilename() and tempfile():
7248 function tempnam() is defined in Visual Studio 6.0 and .NET
7250 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7252 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7253 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7254 - removed compiler command line option /WX: Treats all warnings as errors
7255 - update a list of source files, included into the project
7257 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7258 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7259 changed project type to Generic Project so that can be correcly converted to VS.NET project
7261 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7263 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7265 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7267 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7268 added return 0 statements after assert() to make compiler happy
7270 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7271 added newline in the def file to keep MSC compiler satisfied
7273 * sdcc/src/z80/gen.c:
7274 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7275 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7276 - solved MSC error in function aopDump()
7278 * sdcc_vc.h: define PREFIX as "\\sdcc"
7280 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7281 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7284 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7285 - Rewrote the register banking algorithm.
7286 - Added pCode live-range analysis to registers (for now, only non-used and
7287 singly-used registers optimized away)
7289 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7291 * 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.

7320 2002-03-28 Johan Knol <johan AT balder>
7322 * src/SDCCval.c: fixed bug #532436
7324 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7326 Added "char *Processor" field to the port structure.
7329 Added -p option. Allows port dependent processor to be specified.
7332 Initialized the new field char *Processor field to NULL in all ports
7335 Compiler generated registers for interrupt context saving
7336 were not getting allocated.
7338 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7341 Fixed left shift. Will promote the left side of a left shift
7342 if a) left shifting more than size of operand or b) when assigned
7343 to something size > size of left side
7345 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7347 tons of changes. Register allocation has been
7348 rewritten. Added customization for the various PICs. Flow
7349 analysis is restructured. ...
7355 Added. device.c is a PIC port hack to accomodate variations
7358 2002-03-13 Michael Hope <michaelh AT vroom>
7360 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

7457 not really partof a loop , but live ranges used in these blocks should
7458 be live thru the entire loop, so set partOfLoop but don't add them to
