2106 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2108 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2110 * device/lib/printf_large.c: removed inline assembly for portability and
2111 readability. Use printf_fast if speed or size are more important.
2112 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2113 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2115 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2117 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2118 prevent compiler warning
2120 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2122 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2123 moved to level 0 and declared as static. Also they are explicit
2124 placed in access bank. This was necessery because some times they
2125 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2126 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2127 optimizations. Currently only compare to unsigned char is implemented,
2128 * src/pic16/gen.c: added fReturnIdx array,
2129 * (struct resolvedIfx) is moved to gen.h and made public,
2130 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2131 * (aopForSym): added an optimization to directly store in stack of
2132 the operand of a SEND iCode,
2133 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2134 but as registers instead (AOP_REG) using the fReturnIdx array,
2135 * (pic16_freeAsmop): remove the freed register from the
2136 _G.sregsAlloc field,
2137 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2138 a compare of 'WREG',
2139 * (pic16_popGetTempRegCond): changed function prototype, now
2140 function takes also a bitVector argument v which holds the current
2141 set of registers that are allocated for stack access by aopForSym,
2142 registers allocated in aopForSym for accessing stack symbols are not
2143 any more part of the functions usedRegs field,
2144 * (genCall): some times aopOp is called for a stack variable to be
2145 send, aopForSym might perform the push, if this is true make sure
2146 that genCall doesn't push the variable twice by testing _G.resDirect,
2147 * (genFunction): changed testing for unspecified interrupt number
2148 from 256 to INTNO_UNSPEC,
2149 * modified selection scheme of frame pointer generation. Previously
2150 if function did use local registers a frame pointer was generated,
2151 now a frame pointer is generated only if function has arguments
2152 (that need PLUSW2 register access), or has stack arguments, or the
2153 compiler is not instructed to omit the frame pointer,
2154 * (genEndFunction): before restoring local registers that were saved
2155 in the function preamble, also restore the registers that *might*
2156 have been allocated for stack access,
2157 * (genRet): removed some old comments,

2159 pic16_genCmp_special function to perform the compare with a more
2160 robust and optimized way,
2161 * (genInline): a feature has been added in inline code generation,
2162 which allows a wildcard variable substitution when writing inline
2163 assembly. Code is incomplete and experimental therefore undocumented,
2164 * (genCast): changed order of aopOp for result and right to allow
2165 aopForSym to directly load the result if possible,

2834 Adding support for replacing ljmps with sjmps in jumptables
2835 generated for switch statements. For now you need to set the
2836 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2837 Now 4 algorithms for mcs51 jumptable generation are used:
2838 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

2872 * added libc directory. The current version of LibC contains string
2873 functions, ctype functions and macros and some functions of the
2874 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2875 be extensively tested in the future. Standard disclaimer here.

2888 * (pic16_storeForReturn): optimized return of 0,
2889 * (genCmp): experimental code for new genCmp which uses PIC18's
2890 special compare&skip instructions. Initial tests fail some times
2891 with variables grater than 1 byte in size, so new code is disabled,
2892 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2894 * (genCast): began a fix to optimize the casting of a bit to another
2895 bit, now assigning a bitfield to another bitfield will fail, sorry,

2904 and 1 for banking instruction,
2905 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2906 caused stop processing pCodes after a inline assembly block,
2907 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2909 registers when it shouldn't,
2910 * src/pic16/ralloc.c (allocReg): add preliminary support for
2911 supporting a limited set of temporary registers,
2913 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2919 (genFunction): optimize RECEIVE iCodes in reentrant functions
2921 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5921 loaded with the linker search paths (-L arguments) and the libraries
5922 to be linked with the current source (-l arguments). Changes
5923 currently will affect only the pic16 port.
5924 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5925 include path the port specific paths and port specific libraries,
5926 * gplink command now contains the $3 argument,
5927 * src/pic16/device.h,
5928 * src/pic16/device.c,: structure PIC_device is made public and

5944 Documenting changes from previous commits.
5945 * configure.in (version 1.56),
5946 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5947 when generating output files to configure the pic16 library,
5948 but now I've commented it out, since gputils aren't installed in the
5949 SF compile farm, so library won't compile
5951 * device/lib/Makefile.in (version 1.56): initially I've added in
5952 target 'all' the prerequestive 'model-pic16' so it compiled the
5953 pic16 library, but now I've commented it out for the same reasons
5955 * added targets 'model-pic16' and 'objects-pic16' to compile the
5957 * added target 'port-specific-objects-pic16' to handle the
5958 generated libraries and copy them into the build/ directory
5959 * added target 'clean-intermediate-pic16' to clean intermediate
5960 files into pic16 directory
5961 * in target 'installdirs' added line to create directory pic16 in

6172 arguments via -W option
6173 * src/pic16/main.c: added $l in _asmCmd, changed extension for
6174 object file from '.rel' to '.o' in port->linker structure,
6175 changed size of fptr from 2 to 3 in port structure
6177 2004-01-07 Borut Razem <borut.razem AT siol.net>
6179 * support/scripts/sdcc.nsi: update PATH

6205 * support/valdiag/tests/overflow.c: added
6206 * src/SDCCast.c (decorateType),
6207 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
6208 LEFT_OP (left shift)
6210 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6212 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6213 (default behaviour).
6215 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6217 A python script to validate compiler diagnostic messages. It can be
6218 used to verify that sdcc complains about bad c source code and
6219 gives a good location of the error.
6220 * support/valdiag/Makefile,
6221 * support/valdiag/valdiag.py,
6222 * support/valdiag/tests/*
6224 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6237 * src/common.h: added ifndef/define/endif macros
6238 around the header file.
6239 Bug reported from Jesus Calvino-Fraga
6241 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6243 * sdcc.spec: updated
6244 * device/include/Makefile.in: don't install CVS directories
6245 * device/lib/Makefile.in: added removal of CVS directories after install
6246 * doc/Makefile: fixed install, added local_icons
6247 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6248 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6249 * src/ds390/gen.c (genRightShift): fixed bug #870788
6250 * src/SDCCast.c (decorateType): fixed bug #870781
6252 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6254 PIC16 port related changes:
6255 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6256 added variable stackPos,
6258 * gen.c: genCall, assignResultValue: added support for
6259 pushing/retrieving function parameters to/from stack,
6260 genFunction,genEndFunction: setup stack frame for the
6262 genAddrOf: will be changed according to bug 863624
6264 * added files genutils.c and genutils.h which contain gen*
6265 debugged and optimised functions extracted from gen.c
6267 * glue.c: added variable 'externs' which holds extern symbols,
6268 pic16emitRegularMap: is modified to properly handle relocatable
6269 symbols under the new scheme,
6270 pic16createInterruptVect: is modified
6271 pic16printPublics: is modified to emit 'global' assembler directives,
6272 added pic16_printExterns to print extern symbols,
6273 pic16glue: initializes stack/frame pointer in the beginning of
6274 the assembly output. Temporary hack, will be corrected later,
6275 because gplink yet does not support stack and SDCC does not
6276 yet support a type of crt0.o object to create the final binary.
6278 * Removed many lines that contain 8051 legacy code.
6279 * The code is finally placed under a 'code' directive.
6280 * Added port specific options.
6282 * _process_pragma: simplified since now we do not need *special*
6283 include file to define SFR registers. But a separate header
6284 will be needed. This will be developed later.
6285 * _pic16_parseOptions: added, parses port specific options:
6286 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6287 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6288 --preplace-udata-with=
6290 * _pic16_setDefaultOptions: modified to initialize section names,
6291 but hack is temporarly out of order since it needs improvement.
6292 * _pic16_genAssemblerPreamble: configuration words are emitted by
6293 their address instead of their name. This part is incomplete and
6294 supports only the 18Fxx2 devices. Other devices will emit an error
6295 during assembly since they do not contain the same set of config
6297 * _pic16_genIVT: is modified,
6299 * pcode.c: added definitions for some hardware registers that are needed
6301 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6302 All PCI entries are updated. Now LFSR is supported.
6303 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6304 * added pic16_newpCodeOpLit2 to support instructions with
6305 two literal arguments
6306 * pic16_pCode2str: corrected code that emits assembler instructions
6307 with two literal operands and those that have an access bit modifier
6308 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6309 this fixes a bug which caused some labels to be lost, when an
6310 assembler directive was added, i.e. banksel,
6311 * pic16_FixRegisterBanking: improved logic that causes the insertion
6313 * InlineFunction: functions that are called once, are not any more
6314 inlined. This can be a port option in the future,
6316 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6318 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6319 hold the corresponding uninitialized symbols,
6320 * pic16_allocProcessorRegister: registers have explicit marked the
6322 * pic16_allocInternalRegister: registers are explicit marked as
6324 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6325 processing list, so bit registers were lost,
6328 * ralloc.h: added field 'accessBank' and original symbol operand
6329 in register definition,
6330 * removed the field isMapped from register definition,
6332 ** Several functions have been removed from various sources:
6333 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6334 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6335 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6336 pic16_assignRelocatableRegisters
6338 ** others have been introduced:
6339 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6340 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6342 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6344 * support/scripts/inc2h.pl: changed definition of BIT_AT
6345 to emit 'sbit at' instead of 'bit at'. This was a request.
6347 PIC16 port related preliminary changes:
6348 * gen.c: prefixed function popRegFromString with
6349 pic16_ and all references to it corrected
6350 * pcode.c: all pic16_pc_* hardware registers prefixed
6351 with underscore (_),
6352 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6353 * ralloc.c: newReg(): when register is REG_SFR then
6354 set address to rIdx,
6355 pic16_allocProcessorRegister(): marks register wasUsed=0
6356 pic16_writeUsedRegs(): added a call to assign processor
6357 registers via pic16_assignFixedRegisters
6359 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6361 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6362 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6363 variables in unused register banks. Also the SSEG is placed
6364 wherever there is enough space for it, and IDATA can be anywhere
6365 in internal RAM. For now compile using -Wl-Y[stack_size].
6366 The mem file is different for this option as well, since it
6367 makes no sense of talking about DSEG lenght.
6369 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6371 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6372 in certain cases, e.g. when ROM assignment, patch provided
6373 from Albert den Haan.

6614 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6616 * src/SDCCast.c (decorateType): disabled a transformation I added in
6617 revision 1.188 (access to fields of a structure at an absolute address);
6618 it breaks with bitfields, extern declarations, and gcse analysis.
6619 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6620 could be assigned through a pointer, so don't complain.

7261 support for standard C idiom of memory mapped variables; for
7262 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7263 to xdata int at 0x1234 tempvar = 1.
7264 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch

7281 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7283 Fixed bug #621531 (const & volatile confusion in the type chain).
7284 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

7376 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7377 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7378 fetching of the pointer
7379 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7380 copied from genNearPointerSet()
7381 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7382 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7383 If they pop r0/r1 they must be called in the opposite order than aopOp().
7384 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7385 (resp. --stack-auto), prepared for --xstack

7398 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7399 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7400 type for bits was changed. It resulted in bit variables becoming
7401 global, which is not permitted in PIC 14 assembly output.
7403 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7418 A few small changes that speed up the peephole optimizer.
7422 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7424 Try to make the peephole optimizer smarter by maintaining
7425 an association between the assembly source code and the
7426 iCodes that originated them. Put this information to use
7427 with a new peephole rule condition "notVolatile" so that
7428 the rules can be aggressive yet still safe.
7433 * src/mcs51/peeph.def
7435 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7439 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7440 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7441 if the left or right operand symbols have the accuse flag set.
7443 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7445 Changed the type of the result of the ! (NOT) operator to char;
7446 previously it returned the same type as the source. This allows
7447 us to eliminate all the genFloatNot functions (all of its target
7448 implementations were very buggy) since !float can use the same
7451 * src/SDCCicode.c (ast2iCode): ! returns char

7460 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7461 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7462 during interrupts. Ensure WSAVE is located at a shared bank address.
7463 2. Fixed page selection in some places
7464 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7465 the registers name strings.
7466 4. Fixed "signed / unsigned compare" compiler warnings.
7467 5. The PIC port manages its own allocation of the general purpose
7468 registers, but makes no attempt to reuse them. As a result when
7469 compiling it soon runs out of general purpose registers. Some
7470 additional code was added to the files pcode.c and device.c to walk
7471 through the function call tree and rename the registers so that they
7481 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7482 genPlus() & genMinus() when the result is the same as left or right

7488 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7490 Made bitfield a distinct type from bit so that bitfields
7491 convert as per ANSI C and bits retain their traditional
7492 boolean style behaviour. Implemented bitfield support in
7500 * src/ds390/gen.c: bit v bitfield split
7501 * src/z80/gen.c: New support for bitfields
7502 * support/regression/tests/bitfields.c: reenabled z80,
7505 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7507 Rules 246.x, 247.x relate to bitfields, the others speed up
7508 access to xdata mapped I/O devices.
7510 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7512 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7514 Cleaned up genPackBits and genUnpackBits and added two helper
7515 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7516 for literal assignments in genPackBits (thanks to Frieder for
7522 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7524 Fixed bug #748310 (pointer to function type mishandled when the
7525 function name is omitted). Also fixed a SIGSEGV when a function
7526 attribute (reentrant, etc) is used on a non-function or on a
7527 function but misplaced before the parameter list.
7529 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7531 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7532 * support/Util/SDCCerr.h,

7554 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7556 Made the constant following the "interrupt" keyword optional. If
7557 omitted, the function will not automatically be given an entry
7558 in the interrupt vector table (similar to #pragma NOIV, but
7559 less syntacticly kludgy). The interrupt number is also now
7560 range checked. Also fixed a bug in the high order bit example

7581 unsigned, but are signed by default
7582 * src/SDCCval.c (constVal): rearranged
7583 * src/SDCCval.c (valMod): preliminary fix
7584 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7626 constants are unsigned; added recognition of "u" flag for unsigned
7627 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7628 * src/SDCCval.c (valDiv, valMod): fixed signdness
7629 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed

8090 added if/endif conditional macros to remove options help
8091 messages from optionsTable when a port is not configured, added
8092 support for the PIc16 port in the ports table, when executing
8093 the compiler with no port specified on command line, a default
8094 port is selected with the new macro DEFAULT_PORT which is
8095 defined in port.h, in setDefaultOptions() linkOptions is removed
8096 from initialization assignment, since now it is a set,
8097 parseCmdLine uses setParseWithComma for linkOptions, in
8098 linkEdit() linkOptions are accessed with new function indexSet()
8099 which returns the i'th item of a set variable. See SDCCset.c, in
8100 linkEdit() when calling buildCmdLine(), added linkOptions as
8101 last argument. Now users can pass arguments to gplink via the
8102 -Wl option, main() uses pic16glue() to glue up pic16 programs

8116 gpasm complaining and test the linkage with gplink, _linkCmd and
8117 _asmCmd changed to be more gplink and gpasm friendly
8118 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8119 produced an error when parsed, peep rule 12 is added to utilize
8120 movff, but it is commented out since the pCode does not support
8121 yet a command with 2 address arguments
8123 2003-05-18 <johan AT balder>
8125 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8152 2003-05-11 Borut Razem <borut.razem AT siol.net>
8154 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9143 2003-01-07 <johan AT balder>
9145 * src/SDCCast.c (decorateType): fixed bug #600035
9147 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>

9158 2003-01-06 <johan AT balder>
9160 * src/SDCCicode.c: fixed array add
9162 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9163 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9164 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9166 2003-01-04 <johan AT balder>
9168 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9170 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9171 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9173 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9174 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9180 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9181 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9183 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9184 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9186 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9188 * in \sdcc\as\mcs51\ changed these files in order to create an
9189 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9190 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9191 following files to include the previous two files: aslink.dsp,
9192 Makefile.aslink, Makefile.bcc, and Makefile.in.
9194 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9195 .adb instead of .cdb
9197 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9199 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9200 value from option --iram-size.
9202 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9204 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9207 2002-09-18 <wiml AT hhhh.org>
9209 * SDCClrange.h: exposed setFromRange() and setToRange()
9210 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9211 packRegsForAccUse() (bug 542397)
9212 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9213 multiple times and emitting the fetch operations more than once
9214 added aopGetUsesAcc() function to allow binary operators to
9215 fetch their operands in the correct order; made genMinus() emit
9216 compact code for X = LITERAL - Y
9218 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9219 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9220 sprintf() in line 1267.
9222 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9223 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9226 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9227 Changes to aslink (All the changes are marked with 'JCF'):
9229 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9232 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9233 area BSEG. Also moves, if possible, the DATA area down into the internal
9234 ram so more space is available.
9236 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9239 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9240 not bytes. Function summary() which creates a memory usage summary
9241 file with extension .mem. Reports of overlaping stack and small stack
9242 size. If the space for the stack is less than 16 bytes aslink trows a
9245 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9246 the 8051. Option 'y' for memory summary output file.
9248 Changes to sdcc (All the changes are marked with 'JCF'):
9250 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9252 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9253 overlaying area for it (uses RegBankUsed[4]).
9255 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9256 bank zero as used by default. By default aslink locates the stack
9257 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9258 the creation of the .mem file. Delegates the allocation of data area
9259 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9260 the begining of the stack area to aslink.
9262 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9263 glue() in SDCCglue.c creates an area for it.
9265 2002-09-03 Borut Razem <borut.razem AT siol.net>
9266 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9267 sdcc/src/pic/glue.c:
9268 introduced atexit() handler for teporay files removal in case of
9269 errors, assertions, ...
9271 2002-08-29 Borut Razem <borut.razem AT siol.net>
9272 * sdcc/support/cpp2/auto-host_vc_in.h:
9273 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9274 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9275 Maybe there is a similar problem with BORLANDC? It should be checked!
9277 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9278 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9279 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9280 was not executed, and the compiler (cl) launched a warning:
9281 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9283 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9284 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9286 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9287 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9289 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9290 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9291 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9292 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9293 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9294 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9295 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9296 - added Release configuration in VS projects
9297 - review of compiler an linker options
9298 - VC .exe files are generated in bin_vc directory, not to interfere
9299 with binaries generated from other projects (cygwin, mingw, bcc ...)
9301 * sdcc/src/yacc.dsp: added
9303 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9304 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9305 and insert the version number definitions from .version
9307 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9309 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9310 added - genarate auto-host.h using auto-host_vc_in.h as template
9313 removed from CVS, generated automatically
9315 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9316 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9318 2002-08-11 Borut Razem <borut.razem AT siol.net>
9319 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9321 2002-08-10 Borut Razem <borut.razem AT siol.net>
9322 * src/SDCCmain.c (main):
9323 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9324 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9325 The consequence was that some temporary files were not removed.
9328 unification of code in functions tempfilename() and tempfile():
9329 function tempnam() is defined in Visual Studio 6.0 and .NET
9331 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9333 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9334 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9335 - removed compiler command line option /WX: Treats all warnings as errors
9336 - update a list of source files, included into the project
9338 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9339 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9340 changed project type to Generic Project so that can be correcly converted to VS.NET project
9342 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9344 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9346 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9348 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9349 added return 0 statements after assert() to make compiler happy
9351 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9352 added newline in the def file to keep MSC compiler satisfied
9354 * sdcc/src/z80/gen.c:
9355 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9356 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9357 - solved MSC error in function aopDump()
9359 * sdcc_vc.h: define PREFIX as "\\sdcc"
9361 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9362 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9364 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9365 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9366 - Rewrote the register banking algorithm.
9367 - Added pCode live-range analysis to registers (for now, only non-used and
9368 singly-used registers optimized away)
9370 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9372 * 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.

9399 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9401 2002-03-28 Johan Knol <johan AT balder>
9403 * src/SDCCval.c: fixed bug #532436
9405 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9407 Added "char *Processor" field to the port structure.
9410 Added -p option. Allows port dependent processor to be specified.
9413 Initialized the new field char *Processor field to NULL in all ports
9416 Compiler generated registers for interrupt context saving
9417 were not getting allocated.
9419 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9422 Fixed left shift. Will promote the left side of a left shift
9423 if a) left shifting more than size of operand or b) when assigned
9424 to something size > size of left side
9426 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9428 tons of changes. Register allocation has been
9429 rewritten. Added customization for the various PICs. Flow
9430 analysis is restructured. ...
9436 Added. device.c is a PIC port hack to accomodate variations
9439 2002-03-13 Michael Hope <michaelh AT vroom>
9441 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9443 2002-03-04 johanknol <johanknol AT manik>
9445 * /src/SDCCval.c: fixed
9447 const unsigned char arr[][2] = { { 0, 1 } };
9448 t18.c:1: error: Initializer element is not constant
9450 2002-03-04 bela <bela AT manik>
9452 * /device/include/mcs51reg.h:
9453 ds89c420 register definition update
9455 2002-03-03 <johan AT FRIJA>

9534 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9536 * sdcc/src/SDCCloop.c:
9537 Previous fix was not good. basic blocks that have "break" or "return" are
9538 not really partof a loop , but live ranges used in these blocks should
9539 be live thru the entire loop, so set partOfLoop but don't add them to
9542 2002-02-21 <johan AT FRIJA>
9544 * src/SDCCcse.c: fixed bug #514308
9546 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9549 Fixed BUG #519583. If a conditional block ended in a return/break
9550 statement inside a loop, it was not being considered part of the loop.
9552 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9554 2002-02-10 Karl Bongers <karl AT turbobit.com>
9557 Fixed up SDCDB debugger somewhat. Updated debugger/README
9558 with lots of comments and notes.
9560 * device/examples/test2.c:
9561 Fix bug, "red" variable not being initialized(compiler complained).
