2159 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2160 moved to level 0 and declared as static. Also they are explicit
2161 placed in access bank. This was necessery because some times they
2162 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2163 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2164 optimizations. Currently only compare to unsigned char is implemented,
2165 * src/pic16/gen.c: added fReturnIdx array,
2166 * (struct resolvedIfx) is moved to gen.h and made public,
2167 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2168 * (aopForSym): added an optimization to directly store in stack of
2169 the operand of a SEND iCode,
2170 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2171 but as registers instead (AOP_REG) using the fReturnIdx array,
2172 * (pic16_freeAsmop): remove the freed register from the
2173 _G.sregsAlloc field,
2174 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2175 a compare of 'WREG',
2176 * (pic16_popGetTempRegCond): changed function prototype, now
2177 function takes also a bitVector argument v which holds the current
2178 set of registers that are allocated for stack access by aopForSym,
2179 registers allocated in aopForSym for accessing stack symbols are not
2180 any more part of the functions usedRegs field,
2181 * (genCall): some times aopOp is called for a stack variable to be
2182 send, aopForSym might perform the push, if this is true make sure
2183 that genCall doesn't push the variable twice by testing _G.resDirect,
2184 * (genFunction): changed testing for unspecified interrupt number
2185 from 256 to INTNO_UNSPEC,
2186 * modified selection scheme of frame pointer generation. Previously
2187 if function did use local registers a frame pointer was generated,
2188 now a frame pointer is generated only if function has arguments
2189 (that need PLUSW2 register access), or has stack arguments, or the
2190 compiler is not instructed to omit the frame pointer,
2191 * (genEndFunction): before restoring local registers that were saved
2192 in the function preamble, also restore the registers that *might*
2193 have been allocated for stack access,
2194 * (genRet): removed some old comments,
2195 * (genCmp, the active (RN's) version): added a call to the
2196 pic16_genCmp_special function to perform the compare with a more
2197 robust and optimized way,
2198 * (genInline): a feature has been added in inline code generation,
2199 which allows a wildcard variable substitution when writing inline
2200 assembly. Code is incomplete and experimental therefore undocumented,
2201 * (genCast): changed order of aopOp for result and right to allow
2202 aopForSym to directly load the result if possible,
2203 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2204 perform an optimized compare on some selected special occasions,
2205 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2206 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2207 generate an IVT any more,
2208 * src/pic16/main.c (pic16_optionsTable): added command line option
2210 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2211 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2213 * src/pic16/NOTES: Raphael Neider added in list of active developers
2214 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2215 jumptable_end to prevent bug #,
2216 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2217 inCond and outCond fields,
2218 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2219 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2220 turn off register spilling,
2221 * (packRegsForOneUse): synced with other ports' versions although it
2222 is not used currently,
2223 * (pic16_packRegisters): added an optimization while reading
2224 structure bitfields, some registers may be saved (malloc code is
2225 decreased by 80 bytes)
2227 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2229 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2230 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2231 this can be optimized more?
2233 2005-03-10 Raphael Neider <rneider AT web.de>
2235 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2236 genNearPointerGet): (hopefully) fixed access to bitfields via
2237 pointers (p->bitN = x; and x = p->bitN; failed)
2239 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2563 access stack and frame pointers. They are initially assigned to
2564 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
2565 accessing SFRs. Updated all occurences of modification of stack or
2566 frame pointer in gen.c and pcode.c,

2872 generated for switch statements. For now you need to set the
2873 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2874 Now 4 algorithms for mcs51 jumptable generation are used:
2875 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2876 addresses loaded pc-relative for up to 112 cases and stack-pushing
2877 target addresses loaded with offset from dptr for up to 256 cases.

2909 * added libc directory. The current version of LibC contains string
2910 functions, ctype functions and macros and some functions of the
2911 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2912 be extensively tested in the future. Standard disclaimer here.

2925 * (pic16_storeForReturn): optimized return of 0,
2926 * (genCmp): experimental code for new genCmp which uses PIC18's
2927 special compare&skip instructions. Initial tests fail some times
2928 with variables grater than 1 byte in size, so new code is disabled,
2929 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2931 * (genCast): began a fix to optimize the casting of a bit to another
2932 bit, now assigning a bitfield to another bitfield will fail, sorry,

2946 registers when it shouldn't,
2947 * src/pic16/ralloc.c (allocReg): add preliminary support for
2948 supporting a limited set of temporary registers,
2950 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5958 loaded with the linker search paths (-L arguments) and the libraries
5959 to be linked with the current source (-l arguments). Changes
5960 currently will affect only the pic16 port.
5961 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5962 include path the port specific paths and port specific libraries,
5963 * gplink command now contains the $3 argument,
5964 * src/pic16/device.h,
5965 * src/pic16/device.c,: structure PIC_device is made public and

5981 Documenting changes from previous commits.
5982 * configure.in (version 1.56),
5983 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5984 when generating output files to configure the pic16 library,
5985 but now I've commented it out, since gputils aren't installed in the
5986 SF compile farm, so library won't compile
5988 * device/lib/Makefile.in (version 1.56): initially I've added in
5989 target 'all' the prerequestive 'model-pic16' so it compiled the
5990 pic16 library, but now I've commented it out for the same reasons
5992 * added targets 'model-pic16' and 'objects-pic16' to compile the
5994 * added target 'port-specific-objects-pic16' to handle the
5995 generated libraries and copy them into the build/ directory
5996 * added target 'clean-intermediate-pic16' to clean intermediate
5997 files into pic16 directory
5998 * in target 'installdirs' added line to create directory pic16 in

6020 option so that it actually works. Made it specific to the z80, since
6021 the gbz80 doesn't have these kinds of I/O ports.
6023 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6245 LEFT_OP (left shift)
6247 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6249 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6250 (default behaviour).
6252 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6254 A python script to validate compiler diagnostic messages. It can be
6255 used to verify that sdcc complains about bad c source code and
6256 gives a good location of the error.
6257 * support/valdiag/Makefile,
6258 * support/valdiag/valdiag.py,
6259 * support/valdiag/tests/*
6261 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6276 Bug reported from Jesus Calvino-Fraga
6278 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6280 * sdcc.spec: updated
6281 * device/include/Makefile.in: don't install CVS directories
6282 * device/lib/Makefile.in: added removal of CVS directories after install
6283 * doc/Makefile: fixed install, added local_icons
6284 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6285 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6286 * src/ds390/gen.c (genRightShift): fixed bug #870788
6287 * src/SDCCast.c (decorateType): fixed bug #870781
6289 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6291 PIC16 port related changes:
6292 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6293 added variable stackPos,
6295 * gen.c: genCall, assignResultValue: added support for
6296 pushing/retrieving function parameters to/from stack,
6297 genFunction,genEndFunction: setup stack frame for the
6299 genAddrOf: will be changed according to bug 863624
6301 * added files genutils.c and genutils.h which contain gen*
6302 debugged and optimised functions extracted from gen.c
6304 * glue.c: added variable 'externs' which holds extern symbols,
6305 pic16emitRegularMap: is modified to properly handle relocatable
6306 symbols under the new scheme,
6307 pic16createInterruptVect: is modified
6308 pic16printPublics: is modified to emit 'global' assembler directives,
6309 added pic16_printExterns to print extern symbols,
6310 pic16glue: initializes stack/frame pointer in the beginning of
6311 the assembly output. Temporary hack, will be corrected later,
6312 because gplink yet does not support stack and SDCC does not
6313 yet support a type of crt0.o object to create the final binary.
6315 * Removed many lines that contain 8051 legacy code.
6316 * The code is finally placed under a 'code' directive.
6317 * Added port specific options.
6319 * _process_pragma: simplified since now we do not need *special*
6320 include file to define SFR registers. But a separate header
6321 will be needed. This will be developed later.
6322 * _pic16_parseOptions: added, parses port specific options:
6323 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6324 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6325 --preplace-udata-with=
6327 * _pic16_setDefaultOptions: modified to initialize section names,
6328 but hack is temporarly out of order since it needs improvement.
6329 * _pic16_genAssemblerPreamble: configuration words are emitted by
6330 their address instead of their name. This part is incomplete and
6331 supports only the 18Fxx2 devices. Other devices will emit an error
6332 during assembly since they do not contain the same set of config
6334 * _pic16_genIVT: is modified,
6336 * pcode.c: added definitions for some hardware registers that are needed
6338 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6339 All PCI entries are updated. Now LFSR is supported.
6340 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6341 * added pic16_newpCodeOpLit2 to support instructions with
6342 two literal arguments
6343 * pic16_pCode2str: corrected code that emits assembler instructions
6344 with two literal operands and those that have an access bit modifier
6345 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6346 this fixes a bug which caused some labels to be lost, when an
6347 assembler directive was added, i.e. banksel,
6348 * pic16_FixRegisterBanking: improved logic that causes the insertion
6350 * InlineFunction: functions that are called once, are not any more
6351 inlined. This can be a port option in the future,
6353 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6355 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6356 hold the corresponding uninitialized symbols,
6357 * pic16_allocProcessorRegister: registers have explicit marked the
6359 * pic16_allocInternalRegister: registers are explicit marked as
6361 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6362 processing list, so bit registers were lost,
6365 * ralloc.h: added field 'accessBank' and original symbol operand
6366 in register definition,
6367 * removed the field isMapped from register definition,
6369 ** Several functions have been removed from various sources:
6370 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6371 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6372 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6373 pic16_assignRelocatableRegisters
6375 ** others have been introduced:
6376 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6377 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6379 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6381 * support/scripts/inc2h.pl: changed definition of BIT_AT
6382 to emit 'sbit at' instead of 'bit at'. This was a request.
6384 PIC16 port related preliminary changes:
6385 * gen.c: prefixed function popRegFromString with
6386 pic16_ and all references to it corrected
6387 * pcode.c: all pic16_pc_* hardware registers prefixed
6388 with underscore (_),
6389 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6390 * ralloc.c: newReg(): when register is REG_SFR then
6391 set address to rIdx,
6392 pic16_allocProcessorRegister(): marks register wasUsed=0
6393 pic16_writeUsedRegs(): added a call to assign processor
6394 registers via pic16_assignFixedRegisters
6396 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6398 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6399 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6400 variables in unused register banks. Also the SSEG is placed
6401 wherever there is enough space for it, and IDATA can be anywhere
6402 in internal RAM. For now compile using -Wl-Y[stack_size].
6403 The mem file is different for this option as well, since it
6404 makes no sense of talking about DSEG lenght.
6406 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6408 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6409 in certain cases, e.g. when ROM assignment, patch provided
6410 from Albert den Haan.
6412 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7414 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7415 fetching of the pointer
7416 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7417 copied from genNearPointerSet()
7418 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7419 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7435 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7436 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7437 type for bits was changed. It resulted in bit variables becoming
7438 global, which is not permitted in PIC 14 assembly output.
7440 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7455 A few small changes that speed up the peephole optimizer.
7459 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7461 Try to make the peephole optimizer smarter by maintaining
7462 an association between the assembly source code and the
7463 iCodes that originated them. Put this information to use
7464 with a new peephole rule condition "notVolatile" so that
7465 the rules can be aggressive yet still safe.
7470 * src/mcs51/peeph.def
7472 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7476 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7477 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7478 if the left or right operand symbols have the accuse flag set.
7480 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7482 Changed the type of the result of the ! (NOT) operator to char;
7483 previously it returned the same type as the source. This allows
7484 us to eliminate all the genFloatNot functions (all of its target
7485 implementations were very buggy) since !float can use the same
7488 * src/SDCCicode.c (ast2iCode): ! returns char

7495 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7497 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7498 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7499 during interrupts. Ensure WSAVE is located at a shared bank address.
7500 2. Fixed page selection in some places
7501 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7502 the registers name strings.
7503 4. Fixed "signed / unsigned compare" compiler warnings.
7504 5. The PIC port manages its own allocation of the general purpose
7505 registers, but makes no attempt to reuse them. As a result when
7506 compiling it soon runs out of general purpose registers. Some
7507 additional code was added to the files pcode.c and device.c to walk
7508 through the function call tree and rename the registers so that they
7518 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7519 genPlus() & genMinus() when the result is the same as left or right

7525 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7527 Made bitfield a distinct type from bit so that bitfields
7528 convert as per ANSI C and bits retain their traditional
7529 boolean style behaviour. Implemented bitfield support in
7537 * src/ds390/gen.c: bit v bitfield split
7538 * src/z80/gen.c: New support for bitfields
7539 * support/regression/tests/bitfields.c: reenabled z80,
7542 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7544 Rules 246.x, 247.x relate to bitfields, the others speed up
7545 access to xdata mapped I/O devices.
7547 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7549 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7551 Cleaned up genPackBits and genUnpackBits and added two helper
7552 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7553 for literal assignments in genPackBits (thanks to Frieder for
7559 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7561 Fixed bug #748310 (pointer to function type mishandled when the
7562 function name is omitted). Also fixed a SIGSEGV when a function
7563 attribute (reentrant, etc) is used on a non-function or on a
7564 function but misplaced before the parameter list.
7566 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7568 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7569 * support/Util/SDCCerr.h,
7570 * support/Util/SDCCerr.c: Added func attr misuse error msg

7591 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7593 Made the constant following the "interrupt" keyword optional. If
7594 omitted, the function will not automatically be given an entry
7595 in the interrupt vector table (similar to #pragma NOIV, but
7596 less syntacticly kludgy). The interrupt number is also now
7597 range checked. Also fixed a bug in the high order bit example

7611 * src/SDCCicode.c (operandOperation): rewritten some ops
7612 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7613 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7615 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7616 be re-activated by defining REDUCE_LITERALS)
7617 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7618 unsigned, but are signed by default
7619 * src/SDCCval.c (constVal): rearranged
7620 * src/SDCCval.c (valMod): preliminary fix
7621 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8126 * src/SDCCmain.c: linkOptions is changed to set *,
8127 added if/endif conditional macros to remove options help
8128 messages from optionsTable when a port is not configured, added
8129 support for the PIc16 port in the ports table, when executing
8130 the compiler with no port specified on command line, a default
8131 port is selected with the new macro DEFAULT_PORT which is
8132 defined in port.h, in setDefaultOptions() linkOptions is removed
8133 from initialization assignment, since now it is a set,
8134 parseCmdLine uses setParseWithComma for linkOptions, in
8135 linkEdit() linkOptions are accessed with new function indexSet()
8136 which returns the i'th item of a set variable. See SDCCset.c, in
8137 linkEdit() when calling buildCmdLine(), added linkOptions as
8138 last argument. Now users can pass arguments to gplink via the
8139 -Wl option, main() uses pic16glue() to glue up pic16 programs

8152 * src/pic16/main.c: __config directives are commented out to stop
8153 gpasm complaining and test the linkage with gplink, _linkCmd and
8154 _asmCmd changed to be more gplink and gpasm friendly
8155 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8156 produced an error when parsed, peep rule 12 is added to utilize
8157 movff, but it is commented out since the pCode does not support
8158 yet a command with 2 address arguments
8160 2003-05-18 <johan AT balder>
8162 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8163 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8181 Fixed so you can set breakpoints prior to run, run does not stop
8182 on entry now. Add tbreak. Other enhancements and fixes for use
8185 2003-05-12 Borut Razem <borut.razem AT siol.net>
8187 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8189 2003-05-11 Borut Razem <borut.razem AT siol.net>
8191 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8192 the path of bin directory, so that PATH is the only env. variable, which has to be set
8193 in case of standard installation.
8194 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9199 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9200 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9201 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9203 2003-01-04 <johan AT balder>
9205 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9207 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9208 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9210 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

9220 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9221 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9223 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9225 * in \sdcc\as\mcs51\ changed these files in order to create an
9226 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9227 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9228 following files to include the previous two files: aslink.dsp,
9229 Makefile.aslink, Makefile.bcc, and Makefile.in.
9231 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9232 .adb instead of .cdb
9234 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9236 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9237 value from option --iram-size.
9239 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9241 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9244 2002-09-18 <wiml AT hhhh.org>
9246 * SDCClrange.h: exposed setFromRange() and setToRange()
9247 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9248 packRegsForAccUse() (bug 542397)
9249 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9250 multiple times and emitting the fetch operations more than once
9251 added aopGetUsesAcc() function to allow binary operators to
9252 fetch their operands in the correct order; made genMinus() emit
9253 compact code for X = LITERAL - Y
9255 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9256 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9257 sprintf() in line 1267.
9259 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9260 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9263 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9264 Changes to aslink (All the changes are marked with 'JCF'):
9266 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9269 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9270 area BSEG. Also moves, if possible, the DATA area down into the internal
9271 ram so more space is available.
9273 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9276 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9277 not bytes. Function summary() which creates a memory usage summary
9278 file with extension .mem. Reports of overlaping stack and small stack
9279 size. If the space for the stack is less than 16 bytes aslink trows a
9282 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9283 the 8051. Option 'y' for memory summary output file.
9285 Changes to sdcc (All the changes are marked with 'JCF'):
9287 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9289 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9290 overlaying area for it (uses RegBankUsed[4]).
9292 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9293 bank zero as used by default. By default aslink locates the stack
9294 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9295 the creation of the .mem file. Delegates the allocation of data area
9296 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9297 the begining of the stack area to aslink.
9299 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9300 glue() in SDCCglue.c creates an area for it.
9302 2002-09-03 Borut Razem <borut.razem AT siol.net>
9303 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9304 sdcc/src/pic/glue.c:
9305 introduced atexit() handler for teporay files removal in case of
9306 errors, assertions, ...
9308 2002-08-29 Borut Razem <borut.razem AT siol.net>
9309 * sdcc/support/cpp2/auto-host_vc_in.h:
9310 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9311 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9312 Maybe there is a similar problem with BORLANDC? It should be checked!
9314 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9315 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9316 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9317 was not executed, and the compiler (cl) launched a warning:
9318 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9320 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9321 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9323 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9324 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9326 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9327 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9328 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9329 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9330 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9331 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9332 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9333 - added Release configuration in VS projects
9334 - review of compiler an linker options
9335 - VC .exe files are generated in bin_vc directory, not to interfere
9336 with binaries generated from other projects (cygwin, mingw, bcc ...)
9338 * sdcc/src/yacc.dsp: added
9340 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9341 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9342 and insert the version number definitions from .version
9344 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9346 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9347 added - genarate auto-host.h using auto-host_vc_in.h as template
9350 removed from CVS, generated automatically
9352 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9353 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9355 2002-08-11 Borut Razem <borut.razem AT siol.net>
9356 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9358 2002-08-10 Borut Razem <borut.razem AT siol.net>
9359 * src/SDCCmain.c (main):
9360 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9361 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9362 The consequence was that some temporary files were not removed.
9365 unification of code in functions tempfilename() and tempfile():
9366 function tempnam() is defined in Visual Studio 6.0 and .NET
9368 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9370 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9371 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9372 - removed compiler command line option /WX: Treats all warnings as errors
9373 - update a list of source files, included into the project
9375 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9376 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9377 changed project type to Generic Project so that can be correcly converted to VS.NET project
9379 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9381 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9383 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9385 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9386 added return 0 statements after assert() to make compiler happy
9388 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9389 added newline in the def file to keep MSC compiler satisfied
9391 * sdcc/src/z80/gen.c:
9392 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9393 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9394 - solved MSC error in function aopDump()
9396 * sdcc_vc.h: define PREFIX as "\\sdcc"
9398 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9399 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9401 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9402 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9403 - Rewrote the register banking algorithm.
9404 - Added pCode live-range analysis to registers (for now, only non-used and
9405 singly-used registers optimized away)
9407 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9409 * 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.

9438 2002-03-28 Johan Knol <johan AT balder>
9440 * src/SDCCval.c: fixed bug #532436
9442 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9444 Added "char *Processor" field to the port structure.
9447 Added -p option. Allows port dependent processor to be specified.
9450 Initialized the new field char *Processor field to NULL in all ports
9453 Compiler generated registers for interrupt context saving
9454 were not getting allocated.
9456 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9459 Fixed left shift. Will promote the left side of a left shift
9460 if a) left shifting more than size of operand or b) when assigned
9461 to something size > size of left side
9463 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9465 tons of changes. Register allocation has been
9466 rewritten. Added customization for the various PICs. Flow
9467 analysis is restructured. ...
9473 Added. device.c is a PIC port hack to accomodate variations

9573 * sdcc/src/SDCCloop.c:
9574 Previous fix was not good. basic blocks that have "break" or "return" are
9575 not really partof a loop , but live ranges used in these blocks should
9576 be live thru the entire loop, so set partOfLoop but don't add them to
