2108 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2110 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2112 * device/lib/printf_large.c: removed inline assembly for portability and
2113 readability. Use printf_fast if speed or size are more important.
2114 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2115 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2117 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2119 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2120 prevent compiler warning
2122 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2124 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2125 moved to level 0 and declared as static. Also they are explicit
2126 placed in access bank. This was necessery because some times they
2127 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2128 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2129 optimizations. Currently only compare to unsigned char is implemented,
2130 * src/pic16/gen.c: added fReturnIdx array,
2131 * (struct resolvedIfx) is moved to gen.h and made public,
2132 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2133 * (aopForSym): added an optimization to directly store in stack of
2134 the operand of a SEND iCode,
2135 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2136 but as registers instead (AOP_REG) using the fReturnIdx array,
2137 * (pic16_freeAsmop): remove the freed register from the
2138 _G.sregsAlloc field,
2139 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2140 a compare of 'WREG',
2141 * (pic16_popGetTempRegCond): changed function prototype, now
2142 function takes also a bitVector argument v which holds the current
2143 set of registers that are allocated for stack access by aopForSym,
2144 registers allocated in aopForSym for accessing stack symbols are not
2145 any more part of the functions usedRegs field,
2146 * (genCall): some times aopOp is called for a stack variable to be
2147 send, aopForSym might perform the push, if this is true make sure
2148 that genCall doesn't push the variable twice by testing _G.resDirect,
2149 * (genFunction): changed testing for unspecified interrupt number
2150 from 256 to INTNO_UNSPEC,
2151 * modified selection scheme of frame pointer generation. Previously
2152 if function did use local registers a frame pointer was generated,
2153 now a frame pointer is generated only if function has arguments
2154 (that need PLUSW2 register access), or has stack arguments, or the
2155 compiler is not instructed to omit the frame pointer,
2156 * (genEndFunction): before restoring local registers that were saved
2157 in the function preamble, also restore the registers that *might*
2158 have been allocated for stack access,
2159 * (genRet): removed some old comments,
2160 * (genCmp, the active (RN's) version): added a call to the
2161 pic16_genCmp_special function to perform the compare with a more
2162 robust and optimized way,
2163 * (genInline): a feature has been added in inline code generation,
2164 which allows a wildcard variable substitution when writing inline
2165 assembly. Code is incomplete and experimental therefore undocumented,
2166 * (genCast): changed order of aopOp for result and right to allow
2167 aopForSym to directly load the result if possible,
2168 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,

2836 Adding support for replacing ljmps with sjmps in jumptables
2837 generated for switch statements. For now you need to set the
2838 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2839 Now 4 algorithms for mcs51 jumptable generation are used:
2840 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

2874 * added libc directory. The current version of LibC contains string
2875 functions, ctype functions and macros and some functions of the
2876 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2877 be extensively tested in the future. Standard disclaimer here.

2890 * (pic16_storeForReturn): optimized return of 0,
2891 * (genCmp): experimental code for new genCmp which uses PIC18's
2892 special compare&skip instructions. Initial tests fail some times
2893 with variables grater than 1 byte in size, so new code is disabled,
2894 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2896 * (genCast): began a fix to optimize the casting of a bit to another
2897 bit, now assigning a bitfield to another bitfield will fail, sorry,

2911 registers when it shouldn't,
2912 * src/pic16/ralloc.c (allocReg): add preliminary support for
2913 supporting a limited set of temporary registers,
2915 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2921 (genFunction): optimize RECEIVE iCodes in reentrant functions
2923 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5922 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5923 loaded with the linker search paths (-L arguments) and the libraries
5924 to be linked with the current source (-l arguments). Changes
5925 currently will affect only the pic16 port.
5926 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5927 include path the port specific paths and port specific libraries,
5928 * gplink command now contains the $3 argument,
5929 * src/pic16/device.h,
5930 * src/pic16/device.c,: structure PIC_device is made public and
5931 renamed to PIC16_device, the same for variable Pics which is renamed

5946 Documenting changes from previous commits.
5947 * configure.in (version 1.56),
5948 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5949 when generating output files to configure the pic16 library,
5950 but now I've commented it out, since gputils aren't installed in the
5951 SF compile farm, so library won't compile
5953 * device/lib/Makefile.in (version 1.56): initially I've added in
5954 target 'all' the prerequestive 'model-pic16' so it compiled the
5955 pic16 library, but now I've commented it out for the same reasons
5957 * added targets 'model-pic16' and 'objects-pic16' to compile the
5959 * added target 'port-specific-objects-pic16' to handle the
5960 generated libraries and copy them into the build/ directory
5961 * added target 'clean-intermediate-pic16' to clean intermediate
5962 files into pic16 directory
5963 * in target 'installdirs' added line to create directory pic16 in

6159 * src/z80/main.c: changed appropriately to configure
6160 needLinkerScript flag
6162 * src/pic16/gen.c (genAddrOf): fixed bug #863624
6163 * src/pic/glue.c: added variable udata_section_name to

6174 arguments via -W option
6175 * src/pic16/main.c: added $l in _asmCmd, changed extension for
6176 object file from '.rel' to '.o' in port->linker structure,
6177 changed size of fptr from 2 to 3 in port structure
6179 2004-01-07 Borut Razem <borut.razem AT siol.net>
6181 * support/scripts/sdcc.nsi: update PATH
6182 * support/scripts/sdcc.ico: craeted

6207 * support/valdiag/tests/overflow.c: added
6208 * src/SDCCast.c (decorateType),
6209 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
6210 LEFT_OP (left shift)
6212 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6214 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6215 (default behaviour).
6217 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6219 A python script to validate compiler diagnostic messages. It can be
6220 used to verify that sdcc complains about bad c source code and
6221 gives a good location of the error.
6222 * support/valdiag/Makefile,
6223 * support/valdiag/valdiag.py,
6224 * support/valdiag/tests/*
6226 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6228 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

6239 * src/common.h: added ifndef/define/endif macros
6240 around the header file.
6241 Bug reported from Jesus Calvino-Fraga
6243 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6245 * sdcc.spec: updated
6246 * device/include/Makefile.in: don't install CVS directories
6247 * device/lib/Makefile.in: added removal of CVS directories after install
6248 * doc/Makefile: fixed install, added local_icons
6249 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6250 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6251 * src/ds390/gen.c (genRightShift): fixed bug #870788
6252 * src/SDCCast.c (decorateType): fixed bug #870781
6254 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6256 PIC16 port related changes:
6257 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6258 added variable stackPos,
6260 * gen.c: genCall, assignResultValue: added support for
6261 pushing/retrieving function parameters to/from stack,
6262 genFunction,genEndFunction: setup stack frame for the
6264 genAddrOf: will be changed according to bug 863624
6266 * added files genutils.c and genutils.h which contain gen*
6267 debugged and optimised functions extracted from gen.c
6269 * glue.c: added variable 'externs' which holds extern symbols,
6270 pic16emitRegularMap: is modified to properly handle relocatable
6271 symbols under the new scheme,
6272 pic16createInterruptVect: is modified
6273 pic16printPublics: is modified to emit 'global' assembler directives,
6274 added pic16_printExterns to print extern symbols,
6275 pic16glue: initializes stack/frame pointer in the beginning of
6276 the assembly output. Temporary hack, will be corrected later,
6277 because gplink yet does not support stack and SDCC does not
6278 yet support a type of crt0.o object to create the final binary.
6280 * Removed many lines that contain 8051 legacy code.
6281 * The code is finally placed under a 'code' directive.
6282 * Added port specific options.
6284 * _process_pragma: simplified since now we do not need *special*
6285 include file to define SFR registers. But a separate header
6286 will be needed. This will be developed later.
6287 * _pic16_parseOptions: added, parses port specific options:
6288 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6289 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6290 --preplace-udata-with=
6292 * _pic16_setDefaultOptions: modified to initialize section names,
6293 but hack is temporarly out of order since it needs improvement.
6294 * _pic16_genAssemblerPreamble: configuration words are emitted by
6295 their address instead of their name. This part is incomplete and
6296 supports only the 18Fxx2 devices. Other devices will emit an error
6297 during assembly since they do not contain the same set of config
6299 * _pic16_genIVT: is modified,
6301 * pcode.c: added definitions for some hardware registers that are needed
6303 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6304 All PCI entries are updated. Now LFSR is supported.
6305 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6306 * added pic16_newpCodeOpLit2 to support instructions with
6307 two literal arguments
6308 * pic16_pCode2str: corrected code that emits assembler instructions
6309 with two literal operands and those that have an access bit modifier
6310 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6311 this fixes a bug which caused some labels to be lost, when an
6312 assembler directive was added, i.e. banksel,
6313 * pic16_FixRegisterBanking: improved logic that causes the insertion
6315 * InlineFunction: functions that are called once, are not any more
6316 inlined. This can be a port option in the future,
6318 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6320 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6321 hold the corresponding uninitialized symbols,
6322 * pic16_allocProcessorRegister: registers have explicit marked the
6324 * pic16_allocInternalRegister: registers are explicit marked as
6326 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6327 processing list, so bit registers were lost,
6330 * ralloc.h: added field 'accessBank' and original symbol operand
6331 in register definition,
6332 * removed the field isMapped from register definition,
6334 ** Several functions have been removed from various sources:
6335 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6336 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6337 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6338 pic16_assignRelocatableRegisters
6340 ** others have been introduced:
6341 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6342 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6344 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6346 * support/scripts/inc2h.pl: changed definition of BIT_AT
6347 to emit 'sbit at' instead of 'bit at'. This was a request.
6349 PIC16 port related preliminary changes:
6350 * gen.c: prefixed function popRegFromString with
6351 pic16_ and all references to it corrected
6352 * pcode.c: all pic16_pc_* hardware registers prefixed
6353 with underscore (_),
6354 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6355 * ralloc.c: newReg(): when register is REG_SFR then
6356 set address to rIdx,
6357 pic16_allocProcessorRegister(): marks register wasUsed=0
6358 pic16_writeUsedRegs(): added a call to assign processor
6359 registers via pic16_assignFixedRegisters
6361 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6363 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6364 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6365 variables in unused register banks. Also the SSEG is placed
6366 wherever there is enough space for it, and IDATA can be anywhere
6367 in internal RAM. For now compile using -Wl-Y[stack_size].
6368 The mem file is different for this option as well, since it
6369 makes no sense of talking about DSEG lenght.
6371 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6373 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6374 in certain cases, e.g. when ROM assignment, patch provided
6375 from Albert den Haan.
6377 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6616 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6618 * src/SDCCast.c (decorateType): disabled a transformation I added in
6619 revision 1.188 (access to fields of a structure at an absolute address);
6620 it breaks with bitfields, extern declarations, and gcse analysis.
6621 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6622 could be assigned through a pointer, so don't complain.

7283 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7285 Fixed bug #621531 (const & volatile confusion in the type chain).
7286 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

7379 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7380 fetching of the pointer
7381 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7382 copied from genNearPointerSet()
7383 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7384 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7385 If they pop r0/r1 they must be called in the opposite order than aopOp().

7400 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7401 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7402 type for bits was changed. It resulted in bit variables becoming
7403 global, which is not permitted in PIC 14 assembly output.
7405 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7420 A few small changes that speed up the peephole optimizer.
7424 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7426 Try to make the peephole optimizer smarter by maintaining
7427 an association between the assembly source code and the
7428 iCodes that originated them. Put this information to use
7429 with a new peephole rule condition "notVolatile" so that
7430 the rules can be aggressive yet still safe.
7435 * src/mcs51/peeph.def
7437 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7441 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7442 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7443 if the left or right operand symbols have the accuse flag set.
7445 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7447 Changed the type of the result of the ! (NOT) operator to char;
7448 previously it returned the same type as the source. This allows
7449 us to eliminate all the genFloatNot functions (all of its target
7450 implementations were very buggy) since !float can use the same
7453 * src/SDCCicode.c (ast2iCode): ! returns char

7462 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7463 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7464 during interrupts. Ensure WSAVE is located at a shared bank address.
7465 2. Fixed page selection in some places
7466 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7467 the registers name strings.
7468 4. Fixed "signed / unsigned compare" compiler warnings.
7469 5. The PIC port manages its own allocation of the general purpose
7470 registers, but makes no attempt to reuse them. As a result when
7471 compiling it soon runs out of general purpose registers. Some
7472 additional code was added to the files pcode.c and device.c to walk
7473 through the function call tree and rename the registers so that they
7483 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7484 genPlus() & genMinus() when the result is the same as left or right

7490 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7492 Made bitfield a distinct type from bit so that bitfields
7493 convert as per ANSI C and bits retain their traditional
7494 boolean style behaviour. Implemented bitfield support in
7502 * src/ds390/gen.c: bit v bitfield split
7503 * src/z80/gen.c: New support for bitfields
7504 * support/regression/tests/bitfields.c: reenabled z80,
7507 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7509 Rules 246.x, 247.x relate to bitfields, the others speed up
7510 access to xdata mapped I/O devices.
7512 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7514 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7516 Cleaned up genPackBits and genUnpackBits and added two helper
7517 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7518 for literal assignments in genPackBits (thanks to Frieder for
7524 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7526 Fixed bug #748310 (pointer to function type mishandled when the
7527 function name is omitted). Also fixed a SIGSEGV when a function
7528 attribute (reentrant, etc) is used on a non-function or on a
7529 function but misplaced before the parameter list.
7531 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7533 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7534 * support/Util/SDCCerr.h,

7556 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7558 Made the constant following the "interrupt" keyword optional. If
7559 omitted, the function will not automatically be given an entry
7560 in the interrupt vector table (similar to #pragma NOIV, but
7561 less syntacticly kludgy). The interrupt number is also now
7562 range checked. Also fixed a bug in the high order bit example

7628 constants are unsigned; added recognition of "u" flag for unsigned
7629 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7630 * src/SDCCval.c (valDiv, valMod): fixed signdness

8092 added if/endif conditional macros to remove options help
8093 messages from optionsTable when a port is not configured, added
8094 support for the PIc16 port in the ports table, when executing
8095 the compiler with no port specified on command line, a default
8096 port is selected with the new macro DEFAULT_PORT which is
8097 defined in port.h, in setDefaultOptions() linkOptions is removed
8098 from initialization assignment, since now it is a set,
8099 parseCmdLine uses setParseWithComma for linkOptions, in
8100 linkEdit() linkOptions are accessed with new function indexSet()
8101 which returns the i'th item of a set variable. See SDCCset.c, in
8102 linkEdit() when calling buildCmdLine(), added linkOptions as
8103 last argument. Now users can pass arguments to gplink via the
8104 -Wl option, main() uses pic16glue() to glue up pic16 programs

8118 gpasm complaining and test the linkage with gplink, _linkCmd and
8119 _asmCmd changed to be more gplink and gpasm friendly
8120 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8121 produced an error when parsed, peep rule 12 is added to utilize
8122 movff, but it is commented out since the pCode does not support
8123 yet a command with 2 address arguments
8125 2003-05-18 <johan AT balder>
8127 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8154 2003-05-11 Borut Razem <borut.razem AT siol.net>
8156 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9145 2003-01-07 <johan AT balder>
9147 * src/SDCCast.c (decorateType): fixed bug #600035
9149 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>

9160 2003-01-06 <johan AT balder>
9162 * src/SDCCicode.c: fixed array add
9164 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9165 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9166 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9168 2003-01-04 <johan AT balder>
9170 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9172 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9173 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9175 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9176 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9182 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9183 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9185 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9186 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9188 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9190 * in \sdcc\as\mcs51\ changed these files in order to create an
9191 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9192 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9193 following files to include the previous two files: aslink.dsp,
9194 Makefile.aslink, Makefile.bcc, and Makefile.in.
9196 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9197 .adb instead of .cdb
9199 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9201 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9202 value from option --iram-size.
9204 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9206 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9209 2002-09-18 <wiml AT hhhh.org>
9211 * SDCClrange.h: exposed setFromRange() and setToRange()
9212 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9213 packRegsForAccUse() (bug 542397)
9214 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9215 multiple times and emitting the fetch operations more than once
9216 added aopGetUsesAcc() function to allow binary operators to
9217 fetch their operands in the correct order; made genMinus() emit
9218 compact code for X = LITERAL - Y
9220 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9221 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9222 sprintf() in line 1267.
9224 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9225 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9228 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9229 Changes to aslink (All the changes are marked with 'JCF'):
9231 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9234 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9235 area BSEG. Also moves, if possible, the DATA area down into the internal
9236 ram so more space is available.
9238 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9241 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9242 not bytes. Function summary() which creates a memory usage summary
9243 file with extension .mem. Reports of overlaping stack and small stack
9244 size. If the space for the stack is less than 16 bytes aslink trows a
9247 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9248 the 8051. Option 'y' for memory summary output file.
9250 Changes to sdcc (All the changes are marked with 'JCF'):
9252 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9254 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9255 overlaying area for it (uses RegBankUsed[4]).
9257 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9258 bank zero as used by default. By default aslink locates the stack
9259 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9260 the creation of the .mem file. Delegates the allocation of data area
9261 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9262 the begining of the stack area to aslink.
9264 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9265 glue() in SDCCglue.c creates an area for it.
9267 2002-09-03 Borut Razem <borut.razem AT siol.net>
9268 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9269 sdcc/src/pic/glue.c:
9270 introduced atexit() handler for teporay files removal in case of
9271 errors, assertions, ...
9273 2002-08-29 Borut Razem <borut.razem AT siol.net>
9274 * sdcc/support/cpp2/auto-host_vc_in.h:
9275 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9276 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9277 Maybe there is a similar problem with BORLANDC? It should be checked!
9279 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9280 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9281 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9282 was not executed, and the compiler (cl) launched a warning:
9283 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9285 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9286 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9288 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9289 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9291 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9292 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9293 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9294 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9295 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9296 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9297 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9298 - added Release configuration in VS projects
9299 - review of compiler an linker options
9300 - VC .exe files are generated in bin_vc directory, not to interfere
9301 with binaries generated from other projects (cygwin, mingw, bcc ...)
9303 * sdcc/src/yacc.dsp: added
9305 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9306 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9307 and insert the version number definitions from .version
9309 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9311 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9312 added - genarate auto-host.h using auto-host_vc_in.h as template
9315 removed from CVS, generated automatically
9317 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9318 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9320 2002-08-11 Borut Razem <borut.razem AT siol.net>
9321 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9323 2002-08-10 Borut Razem <borut.razem AT siol.net>
9324 * src/SDCCmain.c (main):
9325 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9326 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9327 The consequence was that some temporary files were not removed.
9330 unification of code in functions tempfilename() and tempfile():
9331 function tempnam() is defined in Visual Studio 6.0 and .NET
9333 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9335 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9336 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9337 - removed compiler command line option /WX: Treats all warnings as errors
9338 - update a list of source files, included into the project
9340 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9341 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9342 changed project type to Generic Project so that can be correcly converted to VS.NET project
9344 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9346 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9348 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9350 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9351 added return 0 statements after assert() to make compiler happy
9353 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9354 added newline in the def file to keep MSC compiler satisfied
9356 * sdcc/src/z80/gen.c:
9357 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9358 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9359 - solved MSC error in function aopDump()
9361 * sdcc_vc.h: define PREFIX as "\\sdcc"
9363 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9364 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9403 2002-03-28 Johan Knol <johan AT balder>
9405 * src/SDCCval.c: fixed bug #532436
9407 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9409 Added "char *Processor" field to the port structure.
9412 Added -p option. Allows port dependent processor to be specified.
9415 Initialized the new field char *Processor field to NULL in all ports
9418 Compiler generated registers for interrupt context saving
9419 were not getting allocated.
9421 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9424 Fixed left shift. Will promote the left side of a left shift
9425 if a) left shifting more than size of operand or b) when assigned
9426 to something size > size of left side
9428 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9430 tons of changes. Register allocation has been
9431 rewritten. Added customization for the various PICs. Flow
9432 analysis is restructured. ...
9438 Added. device.c is a PIC port hack to accomodate variations
9441 2002-03-13 Michael Hope <michaelh AT vroom>
9443 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9445 2002-03-04 johanknol <johanknol AT manik>
9447 * /src/SDCCval.c: fixed
9449 const unsigned char arr[][2] = { { 0, 1 } };
9450 t18.c:1: error: Initializer element is not constant
9452 2002-03-04 bela <bela AT manik>
9454 * /device/include/mcs51reg.h:
9455 ds89c420 register definition update

9536 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9538 * sdcc/src/SDCCloop.c:
9539 Previous fix was not good. basic blocks that have "break" or "return" are
9540 not really partof a loop , but live ranges used in these blocks should
9541 be live thru the entire loop, so set partOfLoop but don't add them to
9544 2002-02-21 <johan AT FRIJA>
9546 * src/SDCCcse.c: fixed bug #514308
9548 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9551 Fixed BUG #519583. If a conditional block ended in a return/break
9552 statement inside a loop, it was not being considered part of the loop.
9554 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9556 2002-02-10 Karl Bongers <karl AT turbobit.com>
9559 Fixed up SDCDB debugger somewhat. Updated debugger/README
9560 with lots of comments and notes.
9562 * device/examples/test2.c:
9563 Fix bug, "red" variable not being initialized(compiler complained).
