2161 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2163 * device/lib/printf_large.c: removed inline assembly for portability and
2164 readability. Use printf_fast if speed or size are more important.
2165 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2166 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2168 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2170 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2171 prevent compiler warning
2173 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2175 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2176 moved to level 0 and declared as static. Also they are explicit
2177 placed in access bank. This was necessery because some times they
2178 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2179 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2180 optimizations. Currently only compare to unsigned char is implemented,
2181 * src/pic16/gen.c: added fReturnIdx array,
2182 * (struct resolvedIfx) is moved to gen.h and made public,
2183 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2184 * (aopForSym): added an optimization to directly store in stack of
2185 the operand of a SEND iCode,
2186 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2187 but as registers instead (AOP_REG) using the fReturnIdx array,
2188 * (pic16_freeAsmop): remove the freed register from the
2189 _G.sregsAlloc field,
2190 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2191 a compare of 'WREG',
2192 * (pic16_popGetTempRegCond): changed function prototype, now
2193 function takes also a bitVector argument v which holds the current
2194 set of registers that are allocated for stack access by aopForSym,
2195 registers allocated in aopForSym for accessing stack symbols are not
2196 any more part of the functions usedRegs field,
2197 * (genCall): some times aopOp is called for a stack variable to be
2198 send, aopForSym might perform the push, if this is true make sure
2199 that genCall doesn't push the variable twice by testing _G.resDirect,
2200 * (genFunction): changed testing for unspecified interrupt number
2201 from 256 to INTNO_UNSPEC,
2202 * modified selection scheme of frame pointer generation. Previously
2203 if function did use local registers a frame pointer was generated,
2204 now a frame pointer is generated only if function has arguments
2205 (that need PLUSW2 register access), or has stack arguments, or the
2206 compiler is not instructed to omit the frame pointer,
2207 * (genEndFunction): before restoring local registers that were saved
2208 in the function preamble, also restore the registers that *might*
2209 have been allocated for stack access,
2210 * (genRet): removed some old comments,
2211 * (genCmp, the active (RN's) version): added a call to the
2212 pic16_genCmp_special function to perform the compare with a more
2213 robust and optimized way,
2214 * (genInline): a feature has been added in inline code generation,
2215 which allows a wildcard variable substitution when writing inline
2216 assembly. Code is incomplete and experimental therefore undocumented,
2217 * (genCast): changed order of aopOp for result and right to allow
2218 aopForSym to directly load the result if possible,
2219 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2220 perform an optimized compare on some selected special occasions,
2221 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2222 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2223 generate an IVT any more,
2224 * src/pic16/main.c (pic16_optionsTable): added command line option
2226 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2227 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2229 * src/pic16/NOTES: Raphael Neider added in list of active developers
2230 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2231 jumptable_end to prevent bug #,
2232 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2233 inCond and outCond fields,
2234 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2235 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2236 turn off register spilling,
2237 * (packRegsForOneUse): synced with other ports' versions although it
2238 is not used currently,
2239 * (pic16_packRegisters): added an optimization while reading
2240 structure bitfields, some registers may be saved (malloc code is
2241 decreased by 80 bytes)
2243 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2245 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2246 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2247 this can be optimized more?
2249 2005-03-10 Raphael Neider <rneider AT web.de>
2251 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2252 genNearPointerGet): (hopefully) fixed access to bitfields via
2253 pointers (p->bitN = x; and x = p->bitN; failed)
2255 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2579 access stack and frame pointers. They are initially assigned to
2580 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
2581 accessing SFRs. Updated all occurences of modification of stack or
2582 frame pointer in gen.c and pcode.c,
2583 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
2584 assigning of a literal value to pointers,

2888 generated for switch statements. For now you need to set the
2889 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2890 Now 4 algorithms for mcs51 jumptable generation are used:
2891 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

2925 * added libc directory. The current version of LibC contains string
2926 functions, ctype functions and macros and some functions of the
2927 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2928 be extensively tested in the future. Standard disclaimer here.
2929 Library is not automatically build yet. But one can build it by

2941 * (pic16_storeForReturn): optimized return of 0,
2942 * (genCmp): experimental code for new genCmp which uses PIC18's
2943 special compare&skip instructions. Initial tests fail some times
2944 with variables grater than 1 byte in size, so new code is disabled,
2945 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2947 * (genCast): began a fix to optimize the casting of a bit to another
2948 bit, now assigning a bitfield to another bitfield will fail, sorry,

2962 registers when it shouldn't,
2963 * src/pic16/ralloc.c (allocReg): add preliminary support for
2964 supporting a limited set of temporary registers,
2966 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2972 (genFunction): optimize RECEIVE iCodes in reentrant functions
2974 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5971 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5973 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5974 loaded with the linker search paths (-L arguments) and the libraries
5975 to be linked with the current source (-l arguments). Changes
5976 currently will affect only the pic16 port.
5977 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5978 include path the port specific paths and port specific libraries,
5979 * gplink command now contains the $3 argument,
5980 * src/pic16/device.h,
5981 * src/pic16/device.c,: structure PIC_device is made public and

5997 Documenting changes from previous commits.
5998 * configure.in (version 1.56),
5999 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6000 when generating output files to configure the pic16 library,
6001 but now I've commented it out, since gputils aren't installed in the
6002 SF compile farm, so library won't compile
6004 * device/lib/Makefile.in (version 1.56): initially I've added in
6005 target 'all' the prerequestive 'model-pic16' so it compiled the
6006 pic16 library, but now I've commented it out for the same reasons
6008 * added targets 'model-pic16' and 'objects-pic16' to compile the
6010 * added target 'port-specific-objects-pic16' to handle the
6011 generated libraries and copy them into the build/ directory
6012 * added target 'clean-intermediate-pic16' to clean intermediate
6013 files into pic16 directory
6014 * in target 'installdirs' added line to create directory pic16 in

6018 added lines to copy all header files to installation path,
6019 * in target 'installdirs' added line create directory for pic16
6020 headers in the installation path

6036 option so that it actually works. Made it specific to the z80, since
6037 the gbz80 doesn't have these kinds of I/O ports.
6039 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6041 * device/include/z180.h,

6068 data are now emitted in sorted order to reduce section naming,
6069 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6070 weren't marked as being in the access bank,

6147 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
6148 UPPER for immediate operands,
6149 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6151 * src/pic16/peeph.def: all peepholes with movff are commented out,
6152 because there is a problem in the pcode peep optimizer,
6153 * src/pic16/ralloc.c: the register allocator can now reuse local
6154 function symbols for another function. This saves register usage.
6155 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6157 Added file src/pic16/NOTES with information about program writing on
6158 the current port version.

6246 include information about variables allocated to the overlay
6249 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6251 * as/mcs51/lkmain.c: Help about -Y option

6261 LEFT_OP (left shift)
6263 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6265 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6266 (default behaviour).
6268 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6270 A python script to validate compiler diagnostic messages. It can be
6271 used to verify that sdcc complains about bad c source code and
6272 gives a good location of the error.
6273 * support/valdiag/Makefile,
6274 * support/valdiag/valdiag.py,
6275 * support/valdiag/tests/*
6277 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6290 * src/common.h: added ifndef/define/endif macros
6291 around the header file.
6292 Bug reported from Jesus Calvino-Fraga
6294 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6296 * sdcc.spec: updated
6297 * device/include/Makefile.in: don't install CVS directories
6298 * device/lib/Makefile.in: added removal of CVS directories after install
6299 * doc/Makefile: fixed install, added local_icons
6300 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6301 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6302 * src/ds390/gen.c (genRightShift): fixed bug #870788
6303 * src/SDCCast.c (decorateType): fixed bug #870781
6305 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6307 PIC16 port related changes:
6308 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6309 added variable stackPos,
6311 * gen.c: genCall, assignResultValue: added support for
6312 pushing/retrieving function parameters to/from stack,
6313 genFunction,genEndFunction: setup stack frame for the
6315 genAddrOf: will be changed according to bug 863624
6317 * added files genutils.c and genutils.h which contain gen*
6318 debugged and optimised functions extracted from gen.c
6320 * glue.c: added variable 'externs' which holds extern symbols,
6321 pic16emitRegularMap: is modified to properly handle relocatable
6322 symbols under the new scheme,
6323 pic16createInterruptVect: is modified
6324 pic16printPublics: is modified to emit 'global' assembler directives,
6325 added pic16_printExterns to print extern symbols,
6326 pic16glue: initializes stack/frame pointer in the beginning of
6327 the assembly output. Temporary hack, will be corrected later,
6328 because gplink yet does not support stack and SDCC does not
6329 yet support a type of crt0.o object to create the final binary.
6331 * Removed many lines that contain 8051 legacy code.
6332 * The code is finally placed under a 'code' directive.
6333 * Added port specific options.
6335 * _process_pragma: simplified since now we do not need *special*
6336 include file to define SFR registers. But a separate header
6337 will be needed. This will be developed later.
6338 * _pic16_parseOptions: added, parses port specific options:
6339 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6340 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6341 --preplace-udata-with=
6343 * _pic16_setDefaultOptions: modified to initialize section names,
6344 but hack is temporarly out of order since it needs improvement.
6345 * _pic16_genAssemblerPreamble: configuration words are emitted by
6346 their address instead of their name. This part is incomplete and
6347 supports only the 18Fxx2 devices. Other devices will emit an error
6348 during assembly since they do not contain the same set of config
6350 * _pic16_genIVT: is modified,
6352 * pcode.c: added definitions for some hardware registers that are needed
6354 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6355 All PCI entries are updated. Now LFSR is supported.
6356 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6357 * added pic16_newpCodeOpLit2 to support instructions with
6358 two literal arguments
6359 * pic16_pCode2str: corrected code that emits assembler instructions
6360 with two literal operands and those that have an access bit modifier
6361 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6362 this fixes a bug which caused some labels to be lost, when an
6363 assembler directive was added, i.e. banksel,
6364 * pic16_FixRegisterBanking: improved logic that causes the insertion
6366 * InlineFunction: functions that are called once, are not any more
6367 inlined. This can be a port option in the future,
6369 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6371 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6372 hold the corresponding uninitialized symbols,
6373 * pic16_allocProcessorRegister: registers have explicit marked the
6375 * pic16_allocInternalRegister: registers are explicit marked as
6377 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6378 processing list, so bit registers were lost,
6381 * ralloc.h: added field 'accessBank' and original symbol operand
6382 in register definition,
6383 * removed the field isMapped from register definition,
6385 ** Several functions have been removed from various sources:
6386 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6387 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6388 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6389 pic16_assignRelocatableRegisters
6391 ** others have been introduced:
6392 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6393 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6395 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6397 * support/scripts/inc2h.pl: changed definition of BIT_AT
6398 to emit 'sbit at' instead of 'bit at'. This was a request.
6400 PIC16 port related preliminary changes:
6401 * gen.c: prefixed function popRegFromString with
6402 pic16_ and all references to it corrected
6403 * pcode.c: all pic16_pc_* hardware registers prefixed
6404 with underscore (_),
6405 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6406 * ralloc.c: newReg(): when register is REG_SFR then
6407 set address to rIdx,
6408 pic16_allocProcessorRegister(): marks register wasUsed=0
6409 pic16_writeUsedRegs(): added a call to assign processor
6410 registers via pic16_assignFixedRegisters
6412 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6414 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6415 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6416 variables in unused register banks. Also the SSEG is placed
6417 wherever there is enough space for it, and IDATA can be anywhere
6418 in internal RAM. For now compile using -Wl-Y[stack_size].
6419 The mem file is different for this option as well, since it
6420 makes no sense of talking about DSEG lenght.
6422 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6424 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6425 in certain cases, e.g. when ROM assignment, patch provided
6426 from Albert den Haan.
6428 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7313 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
7314 support for standard C idiom of memory mapped variables; for
7315 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7316 to xdata int at 0x1234 tempvar = 1.

7430 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7431 fetching of the pointer
7432 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7433 copied from genNearPointerSet()
7434 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7435 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7449 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7451 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7452 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7453 type for bits was changed. It resulted in bit variables becoming
7454 global, which is not permitted in PIC 14 assembly output.
7456 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7458 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7471 A few small changes that speed up the peephole optimizer.
7475 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7477 Try to make the peephole optimizer smarter by maintaining
7478 an association between the assembly source code and the
7479 iCodes that originated them. Put this information to use
7480 with a new peephole rule condition "notVolatile" so that
7481 the rules can be aggressive yet still safe.
7486 * src/mcs51/peeph.def
7488 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7492 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7493 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7494 if the left or right operand symbols have the accuse flag set.
7496 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7498 Changed the type of the result of the ! (NOT) operator to char;
7499 previously it returned the same type as the source. This allows
7500 us to eliminate all the genFloatNot functions (all of its target
7501 implementations were very buggy) since !float can use the same
7504 * src/SDCCicode.c (ast2iCode): ! returns char

7513 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7514 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7515 during interrupts. Ensure WSAVE is located at a shared bank address.
7516 2. Fixed page selection in some places
7517 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7518 the registers name strings.
7519 4. Fixed "signed / unsigned compare" compiler warnings.
7520 5. The PIC port manages its own allocation of the general purpose
7521 registers, but makes no attempt to reuse them. As a result when
7522 compiling it soon runs out of general purpose registers. Some
7523 additional code was added to the files pcode.c and device.c to walk
7524 through the function call tree and rename the registers so that they
7534 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7535 genPlus() & genMinus() when the result is the same as left or right

7541 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7543 Made bitfield a distinct type from bit so that bitfields
7544 convert as per ANSI C and bits retain their traditional
7545 boolean style behaviour. Implemented bitfield support in
7553 * src/ds390/gen.c: bit v bitfield split
7554 * src/z80/gen.c: New support for bitfields
7555 * support/regression/tests/bitfields.c: reenabled z80,
7558 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7560 Rules 246.x, 247.x relate to bitfields, the others speed up
7561 access to xdata mapped I/O devices.
7563 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7565 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7567 Cleaned up genPackBits and genUnpackBits and added two helper
7568 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7569 for literal assignments in genPackBits (thanks to Frieder for
7575 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7577 Fixed bug #748310 (pointer to function type mishandled when the
7578 function name is omitted). Also fixed a SIGSEGV when a function
7579 attribute (reentrant, etc) is used on a non-function or on a
7580 function but misplaced before the parameter list.
7582 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7584 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7585 * support/Util/SDCCerr.h,

7607 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7609 Made the constant following the "interrupt" keyword optional. If
7610 omitted, the function will not automatically be given an entry
7611 in the interrupt vector table (similar to #pragma NOIV, but
7612 less syntacticly kludgy). The interrupt number is also now
7613 range checked. Also fixed a bug in the high order bit example

7627 * src/SDCCicode.c (operandOperation): rewritten some ops
7628 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7629 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7631 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7632 be re-activated by defining REDUCE_LITERALS)
7633 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7634 unsigned, but are signed by default
7635 * src/SDCCval.c (constVal): rearranged
7636 * src/SDCCval.c (valMod): preliminary fix
7637 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8143 added if/endif conditional macros to remove options help
8144 messages from optionsTable when a port is not configured, added
8145 support for the PIc16 port in the ports table, when executing
8146 the compiler with no port specified on command line, a default
8147 port is selected with the new macro DEFAULT_PORT which is
8148 defined in port.h, in setDefaultOptions() linkOptions is removed
8149 from initialization assignment, since now it is a set,
8150 parseCmdLine uses setParseWithComma for linkOptions, in
8151 linkEdit() linkOptions are accessed with new function indexSet()
8152 which returns the i'th item of a set variable. See SDCCset.c, in
8153 linkEdit() when calling buildCmdLine(), added linkOptions as
8154 last argument. Now users can pass arguments to gplink via the
8155 -Wl option, main() uses pic16glue() to glue up pic16 programs

8168 * src/pic16/main.c: __config directives are commented out to stop
8169 gpasm complaining and test the linkage with gplink, _linkCmd and
8170 _asmCmd changed to be more gplink and gpasm friendly
8171 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8172 produced an error when parsed, peep rule 12 is added to utilize
8173 movff, but it is commented out since the pCode does not support
8174 yet a command with 2 address arguments
8176 2003-05-18 <johan AT balder>
8178 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8197 Fixed so you can set breakpoints prior to run, run does not stop
8198 on entry now. Add tbreak. Other enhancements and fixes for use
8201 2003-05-12 Borut Razem <borut.razem AT siol.net>
8203 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8205 2003-05-11 Borut Razem <borut.razem AT siol.net>
8207 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9213 * src/SDCCicode.c: fixed array add
9215 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9216 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9217 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9219 2003-01-04 <johan AT balder>
9221 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9223 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9224 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9226 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9227 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9236 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9237 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9239 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9241 * in \sdcc\as\mcs51\ changed these files in order to create an
9242 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9243 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9244 following files to include the previous two files: aslink.dsp,
9245 Makefile.aslink, Makefile.bcc, and Makefile.in.
9247 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9248 .adb instead of .cdb
9250 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9252 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9253 value from option --iram-size.
9255 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9257 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9260 2002-09-18 <wiml AT hhhh.org>
9262 * SDCClrange.h: exposed setFromRange() and setToRange()
9263 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9264 packRegsForAccUse() (bug 542397)
9265 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9266 multiple times and emitting the fetch operations more than once
9267 added aopGetUsesAcc() function to allow binary operators to
9268 fetch their operands in the correct order; made genMinus() emit
9269 compact code for X = LITERAL - Y
9271 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9272 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9273 sprintf() in line 1267.
9275 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9276 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9279 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9280 Changes to aslink (All the changes are marked with 'JCF'):
9282 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9285 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9286 area BSEG. Also moves, if possible, the DATA area down into the internal
9287 ram so more space is available.
9289 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9292 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9293 not bytes. Function summary() which creates a memory usage summary
9294 file with extension .mem. Reports of overlaping stack and small stack
9295 size. If the space for the stack is less than 16 bytes aslink trows a
9298 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9299 the 8051. Option 'y' for memory summary output file.
9301 Changes to sdcc (All the changes are marked with 'JCF'):
9303 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9305 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9306 overlaying area for it (uses RegBankUsed[4]).
9308 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9309 bank zero as used by default. By default aslink locates the stack
9310 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9311 the creation of the .mem file. Delegates the allocation of data area
9312 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9313 the begining of the stack area to aslink.
9315 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9316 glue() in SDCCglue.c creates an area for it.
9318 2002-09-03 Borut Razem <borut.razem AT siol.net>
9319 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9320 sdcc/src/pic/glue.c:
9321 introduced atexit() handler for teporay files removal in case of
9322 errors, assertions, ...
9324 2002-08-29 Borut Razem <borut.razem AT siol.net>
9325 * sdcc/support/cpp2/auto-host_vc_in.h:
9326 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9327 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9328 Maybe there is a similar problem with BORLANDC? It should be checked!
9330 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9331 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9332 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9333 was not executed, and the compiler (cl) launched a warning:
9334 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9336 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9337 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9339 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9340 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9342 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9343 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9344 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9345 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9346 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9347 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9348 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9349 - added Release configuration in VS projects
9350 - review of compiler an linker options
9351 - VC .exe files are generated in bin_vc directory, not to interfere
9352 with binaries generated from other projects (cygwin, mingw, bcc ...)
9354 * sdcc/src/yacc.dsp: added
9356 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9357 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9358 and insert the version number definitions from .version
9360 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9362 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9363 added - genarate auto-host.h using auto-host_vc_in.h as template
9366 removed from CVS, generated automatically
9368 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9369 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9371 2002-08-11 Borut Razem <borut.razem AT siol.net>
9372 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9374 2002-08-10 Borut Razem <borut.razem AT siol.net>
9375 * src/SDCCmain.c (main):
9376 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9377 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9378 The consequence was that some temporary files were not removed.
9381 unification of code in functions tempfilename() and tempfile():
9382 function tempnam() is defined in Visual Studio 6.0 and .NET
9384 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9386 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9387 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9388 - removed compiler command line option /WX: Treats all warnings as errors
9389 - update a list of source files, included into the project
9391 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9392 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9393 changed project type to Generic Project so that can be correcly converted to VS.NET project
9395 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9397 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9399 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9401 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9402 added return 0 statements after assert() to make compiler happy
9404 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9405 added newline in the def file to keep MSC compiler satisfied
9407 * sdcc/src/z80/gen.c:
9408 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9409 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9410 - solved MSC error in function aopDump()
9412 * sdcc_vc.h: define PREFIX as "\\sdcc"
9414 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9415 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9417 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9418 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9419 - Rewrote the register banking algorithm.
9420 - Added pCode live-range analysis to registers (for now, only non-used and
9421 singly-used registers optimized away)
9423 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9425 * 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.

9454 2002-03-28 Johan Knol <johan AT balder>
9456 * src/SDCCval.c: fixed bug #532436
9458 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9460 Added "char *Processor" field to the port structure.
9463 Added -p option. Allows port dependent processor to be specified.
9466 Initialized the new field char *Processor field to NULL in all ports
9469 Compiler generated registers for interrupt context saving
9470 were not getting allocated.
9472 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9475 Fixed left shift. Will promote the left side of a left shift
9476 if a) left shifting more than size of operand or b) when assigned
9477 to something size > size of left side
9479 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9481 tons of changes. Register allocation has been
9482 rewritten. Added customization for the various PICs. Flow
9483 analysis is restructured. ...
9489 Added. device.c is a PIC port hack to accomodate variations
9492 2002-03-13 Michael Hope <michaelh AT vroom>
9494 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

9590 Previous fix was not good. basic blocks that have "break" or "return" are
9591 not really partof a loop , but live ranges used in these blocks should
9592 be live thru the entire loop, so set partOfLoop but don't add them to
