2177 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
2178 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
2179 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
2180 immedDom() returning wrong block; probably fixes bug #1160833)
2182 2005-03-20 Borut Razem <borut.razem AT siol.net>
2184 * support/scripts/inc2h.pl: WIN32 port
2186 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
2188 * device/lib/makefile.in: added abs.c and labs.c
2190 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
2192 * device/include/stdint.h: added
2193 * device/lib/abs.c: added
2194 * device/lib/labs.c: added
2195 * device/include/stdlib.h: added abs() and labs() prototypes
2196 * device/lib/libsdcc.lib: added abs and labs
2197 * device/include/float.h,
2198 * device/lib/_fsmul.c,
2199 * device/lib/printf_fast.c,
2200 * device/lib/printf_tiny.c: updated comments
2202 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2204 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
2207 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2209 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
2210 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2212 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2214 * device/lib/printf_large.c: removed inline assembly for portability and
2215 readability. Use printf_fast if speed or size are more important.
2216 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2217 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2219 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2221 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2222 prevent compiler warning
2224 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2226 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2227 moved to level 0 and declared as static. Also they are explicit
2228 placed in access bank. This was necessery because some times they
2229 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2230 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2231 optimizations. Currently only compare to unsigned char is implemented,
2232 * src/pic16/gen.c: added fReturnIdx array,
2233 * (struct resolvedIfx) is moved to gen.h and made public,
2234 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2235 * (aopForSym): added an optimization to directly store in stack of
2236 the operand of a SEND iCode,
2237 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2238 but as registers instead (AOP_REG) using the fReturnIdx array,
2239 * (pic16_freeAsmop): remove the freed register from the
2240 _G.sregsAlloc field,
2241 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2242 a compare of 'WREG',
2243 * (pic16_popGetTempRegCond): changed function prototype, now
2244 function takes also a bitVector argument v which holds the current
2245 set of registers that are allocated for stack access by aopForSym,
2246 registers allocated in aopForSym for accessing stack symbols are not
2247 any more part of the functions usedRegs field,
2248 * (genCall): some times aopOp is called for a stack variable to be
2249 send, aopForSym might perform the push, if this is true make sure
2250 that genCall doesn't push the variable twice by testing _G.resDirect,
2251 * (genFunction): changed testing for unspecified interrupt number
2252 from 256 to INTNO_UNSPEC,
2253 * modified selection scheme of frame pointer generation. Previously
2254 if function did use local registers a frame pointer was generated,
2255 now a frame pointer is generated only if function has arguments
2256 (that need PLUSW2 register access), or has stack arguments, or the
2257 compiler is not instructed to omit the frame pointer,
2258 * (genEndFunction): before restoring local registers that were saved
2259 in the function preamble, also restore the registers that *might*
2260 have been allocated for stack access,
2261 * (genRet): removed some old comments,
2262 * (genCmp, the active (RN's) version): added a call to the
2263 pic16_genCmp_special function to perform the compare with a more
2264 robust and optimized way,
2265 * (genInline): a feature has been added in inline code generation,
2266 which allows a wildcard variable substitution when writing inline
2267 assembly. Code is incomplete and experimental therefore undocumented,
2268 * (genCast): changed order of aopOp for result and right to allow
2269 aopForSym to directly load the result if possible,
2270 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2271 perform an optimized compare on some selected special occasions,
2272 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2273 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2274 generate an IVT any more,
2275 * src/pic16/main.c (pic16_optionsTable): added command line option
2277 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2278 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2280 * src/pic16/NOTES: Raphael Neider added in list of active developers
2281 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2282 jumptable_end to prevent bug #,
2283 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2284 inCond and outCond fields,
2285 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2286 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2287 turn off register spilling,
2288 * (packRegsForOneUse): synced with other ports' versions although it
2289 is not used currently,
2290 * (pic16_packRegisters): added an optimization while reading
2291 structure bitfields, some registers may be saved (malloc code is
2292 decreased by 80 bytes)
2294 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2296 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2297 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2298 this can be optimized more?
2300 2005-03-10 Raphael Neider <rneider AT web.de>
2302 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2303 genNearPointerGet): (hopefully) fixed access to bitfields via
2304 pointers (p->bitN = x; and x = p->bitN; failed)
2306 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2349 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
2350 to keep the correct label reference count when adding/removing references
2351 to labels. A peephole file using this is appended to patch #1144962.

2494 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
2495 this might fix SIGSEGVs on MinGW...
2496 * src/SDCCopt.c (killDeadCode): restored original behaviour
2497 (volatile operands might get thrown away though)
2499 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2977 functions, ctype functions and macros and some functions of the
2978 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2979 be extensively tested in the future. Standard disclaimer here.

2994 special compare&skip instructions. Initial tests fail some times
2995 with variables grater than 1 byte in size, so new code is disabled,
2996 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2998 * (genCast): began a fix to optimize the casting of a bit to another
2999 bit, now assigning a bitfield to another bitfield will fail, sorry,

3014 * src/pic16/ralloc.c (allocReg): add preliminary support for
3015 supporting a limited set of temporary registers,
3017 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3023 (genFunction): optimize RECEIVE iCodes in reentrant functions
3025 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3027 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6022 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6024 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6025 loaded with the linker search paths (-L arguments) and the libraries
6026 to be linked with the current source (-l arguments). Changes
6027 currently will affect only the pic16 port.
6028 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6029 include path the port specific paths and port specific libraries,
6030 * gplink command now contains the $3 argument,
6031 * src/pic16/device.h,
6032 * src/pic16/device.c,: structure PIC_device is made public and
6033 renamed to PIC16_device, the same for variable Pics which is renamed

6048 Documenting changes from previous commits.
6049 * configure.in (version 1.56),
6050 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6051 when generating output files to configure the pic16 library,
6052 but now I've commented it out, since gputils aren't installed in the
6053 SF compile farm, so library won't compile
6055 * device/lib/Makefile.in (version 1.56): initially I've added in
6056 target 'all' the prerequestive 'model-pic16' so it compiled the
6057 pic16 library, but now I've commented it out for the same reasons
6059 * added targets 'model-pic16' and 'objects-pic16' to compile the
6061 * added target 'port-specific-objects-pic16' to handle the
6062 generated libraries and copy them into the build/ directory
6063 * added target 'clean-intermediate-pic16' to clean intermediate
6064 files into pic16 directory
6065 * in target 'installdirs' added line to create directory pic16 in
6066 the installation path
6068 * device/include/Makefile.in (version 1.11): in target 'install'
6069 added lines to copy all header files to installation path,
6070 * in target 'installdirs' added line create directory for pic16
6071 headers in the installation path

6086 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6087 option so that it actually works. Made it specific to the z80, since
6088 the gbz80 doesn't have these kinds of I/O ports.
6090 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6092 * device/include/z180.h,

6116 via literal number. The symbol is placed in the corresponding
6117 position of the data ram
6118 * (pic16_dump_section): relocatable and absolute uninitialized
6119 data are now emitted in sorted order to reduce section naming,
6120 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6121 weren't marked as being in the access bank,
6123 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6125 Added portion of GNU PIC Library under the directory
6126 device/include/pic16 and device/lib/pic16. These files
6127 contain the declarations of SFRs for the PIC18Fxx2 devices.
6128 The directory is initialized via configure from toplevel.

6155 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6157 * doc/sdccman.lyx: Moved and added some sections, small changes
6158 all over. Telling LaTeX to be less strict with word spacing
6159 to better keep the right margin. Changed some notes about
6160 maintainance of the ports in section 3.2.1 - is it OK like this?
6162 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
6164 SDCC source changes:
6165 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

6199 UPPER for immediate operands,
6200 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6202 * src/pic16/peeph.def: all peepholes with movff are commented out,
6203 because there is a problem in the pcode peep optimizer,
6204 * src/pic16/ralloc.c: the register allocator can now reuse local

6314 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6316 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6317 (default behaviour).
6319 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6321 A python script to validate compiler diagnostic messages. It can be
6322 used to verify that sdcc complains about bad c source code and
6323 gives a good location of the error.
6324 * support/valdiag/Makefile,
6325 * support/valdiag/valdiag.py,
6326 * support/valdiag/tests/*

6341 * src/common.h: added ifndef/define/endif macros
6342 around the header file.
6343 Bug reported from Jesus Calvino-Fraga
6345 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6347 * sdcc.spec: updated
6348 * device/include/Makefile.in: don't install CVS directories
6349 * device/lib/Makefile.in: added removal of CVS directories after install
6350 * doc/Makefile: fixed install, added local_icons
6351 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6352 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6353 * src/ds390/gen.c (genRightShift): fixed bug #870788
6354 * src/SDCCast.c (decorateType): fixed bug #870781
6356 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6358 PIC16 port related changes:
6359 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6360 added variable stackPos,
6362 * gen.c: genCall, assignResultValue: added support for
6363 pushing/retrieving function parameters to/from stack,
6364 genFunction,genEndFunction: setup stack frame for the
6366 genAddrOf: will be changed according to bug 863624
6368 * added files genutils.c and genutils.h which contain gen*
6369 debugged and optimised functions extracted from gen.c
6371 * glue.c: added variable 'externs' which holds extern symbols,
6372 pic16emitRegularMap: is modified to properly handle relocatable
6373 symbols under the new scheme,
6374 pic16createInterruptVect: is modified
6375 pic16printPublics: is modified to emit 'global' assembler directives,
6376 added pic16_printExterns to print extern symbols,
6377 pic16glue: initializes stack/frame pointer in the beginning of
6378 the assembly output. Temporary hack, will be corrected later,
6379 because gplink yet does not support stack and SDCC does not
6380 yet support a type of crt0.o object to create the final binary.
6382 * Removed many lines that contain 8051 legacy code.
6383 * The code is finally placed under a 'code' directive.
6384 * Added port specific options.
6386 * _process_pragma: simplified since now we do not need *special*
6387 include file to define SFR registers. But a separate header
6388 will be needed. This will be developed later.
6389 * _pic16_parseOptions: added, parses port specific options:
6390 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6391 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6392 --preplace-udata-with=
6394 * _pic16_setDefaultOptions: modified to initialize section names,
6395 but hack is temporarly out of order since it needs improvement.
6396 * _pic16_genAssemblerPreamble: configuration words are emitted by
6397 their address instead of their name. This part is incomplete and
6398 supports only the 18Fxx2 devices. Other devices will emit an error
6399 during assembly since they do not contain the same set of config
6401 * _pic16_genIVT: is modified,
6403 * pcode.c: added definitions for some hardware registers that are needed
6405 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6406 All PCI entries are updated. Now LFSR is supported.
6407 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6408 * added pic16_newpCodeOpLit2 to support instructions with
6409 two literal arguments
6410 * pic16_pCode2str: corrected code that emits assembler instructions
6411 with two literal operands and those that have an access bit modifier
6412 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6413 this fixes a bug which caused some labels to be lost, when an
6414 assembler directive was added, i.e. banksel,
6415 * pic16_FixRegisterBanking: improved logic that causes the insertion
6417 * InlineFunction: functions that are called once, are not any more
6418 inlined. This can be a port option in the future,
6420 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6422 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6423 hold the corresponding uninitialized symbols,
6424 * pic16_allocProcessorRegister: registers have explicit marked the
6426 * pic16_allocInternalRegister: registers are explicit marked as
6428 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6429 processing list, so bit registers were lost,
6432 * ralloc.h: added field 'accessBank' and original symbol operand
6433 in register definition,
6434 * removed the field isMapped from register definition,
6436 ** Several functions have been removed from various sources:
6437 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6438 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6439 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6440 pic16_assignRelocatableRegisters
6442 ** others have been introduced:
6443 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6444 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6446 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6448 * support/scripts/inc2h.pl: changed definition of BIT_AT
6449 to emit 'sbit at' instead of 'bit at'. This was a request.
6451 PIC16 port related preliminary changes:
6452 * gen.c: prefixed function popRegFromString with
6453 pic16_ and all references to it corrected
6454 * pcode.c: all pic16_pc_* hardware registers prefixed
6455 with underscore (_),
6456 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6457 * ralloc.c: newReg(): when register is REG_SFR then
6458 set address to rIdx,
6459 pic16_allocProcessorRegister(): marks register wasUsed=0
6460 pic16_writeUsedRegs(): added a call to assign processor
6461 registers via pic16_assignFixedRegisters
6463 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6465 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6466 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6467 variables in unused register banks. Also the SSEG is placed
6468 wherever there is enough space for it, and IDATA can be anywhere
6469 in internal RAM. For now compile using -Wl-Y[stack_size].
6470 The mem file is different for this option as well, since it
6471 makes no sense of talking about DSEG lenght.
6473 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6475 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6476 in certain cases, e.g. when ROM assignment, patch provided
6477 from Albert den Haan.
6479 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6622 * src/mcs51/peephole.def,
6623 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
6624 (allows non-interrupt and interrupt code to safely compete for a resource

7502 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7503 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7504 type for bits was changed. It resulted in bit variables becoming

7522 A few small changes that speed up the peephole optimizer.
7526 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7528 Try to make the peephole optimizer smarter by maintaining
7529 an association between the assembly source code and the
7530 iCodes that originated them. Put this information to use
7531 with a new peephole rule condition "notVolatile" so that
7532 the rules can be aggressive yet still safe.
7537 * src/mcs51/peeph.def
7539 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7543 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7544 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7545 if the left or right operand symbols have the accuse flag set.
7547 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7549 Changed the type of the result of the ! (NOT) operator to char;
7550 previously it returned the same type as the source. This allows
7551 us to eliminate all the genFloatNot functions (all of its target
7552 implementations were very buggy) since !float can use the same
7555 * src/SDCCicode.c (ast2iCode): ! returns char

7564 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7565 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7566 during interrupts. Ensure WSAVE is located at a shared bank address.
7567 2. Fixed page selection in some places
7568 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7569 the registers name strings.
7570 4. Fixed "signed / unsigned compare" compiler warnings.
7571 5. The PIC port manages its own allocation of the general purpose
7572 registers, but makes no attempt to reuse them. As a result when
7573 compiling it soon runs out of general purpose registers. Some
7574 additional code was added to the files pcode.c and device.c to walk
7575 through the function call tree and rename the registers so that they
7585 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7592 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7594 Made bitfield a distinct type from bit so that bitfields
7595 convert as per ANSI C and bits retain their traditional
7596 boolean style behaviour. Implemented bitfield support in
7604 * src/ds390/gen.c: bit v bitfield split
7605 * src/z80/gen.c: New support for bitfields
7606 * support/regression/tests/bitfields.c: reenabled z80,
7609 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7611 Rules 246.x, 247.x relate to bitfields, the others speed up
7612 access to xdata mapped I/O devices.
7614 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7616 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7618 Cleaned up genPackBits and genUnpackBits and added two helper

7628 Fixed bug #748310 (pointer to function type mishandled when the
7629 function name is omitted). Also fixed a SIGSEGV when a function
7630 attribute (reentrant, etc) is used on a non-function or on a
7631 function but misplaced before the parameter list.

7658 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7660 Made the constant following the "interrupt" keyword optional. If
7661 omitted, the function will not automatically be given an entry
7662 in the interrupt vector table (similar to #pragma NOIV, but
7663 less syntacticly kludgy). The interrupt number is also now
7664 range checked. Also fixed a bug in the high order bit example
7671 * support/Util/SDCCerr.c
7672 * support/Util/SDCCerr.h

8194 added if/endif conditional macros to remove options help
8195 messages from optionsTable when a port is not configured, added
8196 support for the PIc16 port in the ports table, when executing
8197 the compiler with no port specified on command line, a default
8198 port is selected with the new macro DEFAULT_PORT which is
8199 defined in port.h, in setDefaultOptions() linkOptions is removed
8200 from initialization assignment, since now it is a set,
8201 parseCmdLine uses setParseWithComma for linkOptions, in
8202 linkEdit() linkOptions are accessed with new function indexSet()
8203 which returns the i'th item of a set variable. See SDCCset.c, in
8204 linkEdit() when calling buildCmdLine(), added linkOptions as
8205 last argument. Now users can pass arguments to gplink via the
8206 -Wl option, main() uses pic16glue() to glue up pic16 programs

9270 2003-01-04 <johan AT balder>
9272 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9274 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9275 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9277 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9278 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9284 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9285 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9287 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9288 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9290 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9292 * in \sdcc\as\mcs51\ changed these files in order to create an
9293 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9294 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9295 following files to include the previous two files: aslink.dsp,
9296 Makefile.aslink, Makefile.bcc, and Makefile.in.
9298 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9299 .adb instead of .cdb
9301 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9303 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9304 value from option --iram-size.
9306 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9308 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9311 2002-09-18 <wiml AT hhhh.org>
9313 * SDCClrange.h: exposed setFromRange() and setToRange()
9314 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9315 packRegsForAccUse() (bug 542397)
9316 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9317 multiple times and emitting the fetch operations more than once
9318 added aopGetUsesAcc() function to allow binary operators to
9319 fetch their operands in the correct order; made genMinus() emit
9320 compact code for X = LITERAL - Y
9322 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9323 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9324 sprintf() in line 1267.
9326 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9327 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9330 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9331 Changes to aslink (All the changes are marked with 'JCF'):
9333 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9336 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9337 area BSEG. Also moves, if possible, the DATA area down into the internal
9338 ram so more space is available.
9340 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9343 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9344 not bytes. Function summary() which creates a memory usage summary
9345 file with extension .mem. Reports of overlaping stack and small stack
9346 size. If the space for the stack is less than 16 bytes aslink trows a
9349 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9350 the 8051. Option 'y' for memory summary output file.
9352 Changes to sdcc (All the changes are marked with 'JCF'):
9354 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9356 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9357 overlaying area for it (uses RegBankUsed[4]).
9359 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9360 bank zero as used by default. By default aslink locates the stack
9361 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9362 the creation of the .mem file. Delegates the allocation of data area
9363 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9364 the begining of the stack area to aslink.
9366 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9367 glue() in SDCCglue.c creates an area for it.
9369 2002-09-03 Borut Razem <borut.razem AT siol.net>
9370 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9371 sdcc/src/pic/glue.c:
9372 introduced atexit() handler for teporay files removal in case of
9373 errors, assertions, ...
9375 2002-08-29 Borut Razem <borut.razem AT siol.net>
9376 * sdcc/support/cpp2/auto-host_vc_in.h:
9377 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9378 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9379 Maybe there is a similar problem with BORLANDC? It should be checked!
9381 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9382 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9383 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9384 was not executed, and the compiler (cl) launched a warning:
9385 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9387 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9388 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9390 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9391 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9393 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9394 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9395 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9396 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9397 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9398 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9399 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9400 - added Release configuration in VS projects
9401 - review of compiler an linker options
9402 - VC .exe files are generated in bin_vc directory, not to interfere
9403 with binaries generated from other projects (cygwin, mingw, bcc ...)
9405 * sdcc/src/yacc.dsp: added
9407 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9408 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9409 and insert the version number definitions from .version
9411 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9413 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9414 added - genarate auto-host.h using auto-host_vc_in.h as template
9417 removed from CVS, generated automatically
9419 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9420 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9422 2002-08-11 Borut Razem <borut.razem AT siol.net>
9423 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9425 2002-08-10 Borut Razem <borut.razem AT siol.net>
9426 * src/SDCCmain.c (main):
9427 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9428 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9429 The consequence was that some temporary files were not removed.
9432 unification of code in functions tempfilename() and tempfile():
9433 function tempnam() is defined in Visual Studio 6.0 and .NET
9435 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9437 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9438 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9439 - removed compiler command line option /WX: Treats all warnings as errors
9440 - update a list of source files, included into the project
9442 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9443 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9444 changed project type to Generic Project so that can be correcly converted to VS.NET project
9446 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9448 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9450 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9452 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9453 added return 0 statements after assert() to make compiler happy
9455 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9456 added newline in the def file to keep MSC compiler satisfied
9458 * sdcc/src/z80/gen.c:
9459 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9460 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9461 - solved MSC error in function aopDump()
9463 * sdcc_vc.h: define PREFIX as "\\sdcc"
9465 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9466 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9468 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9469 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9470 - Rewrote the register banking algorithm.
9471 - Added pCode live-range analysis to registers (for now, only non-used and
9472 singly-used registers optimized away)
9474 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9476 * 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.
9478 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9479 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9481 2002-04-22 Michael Hope <michaelh AT vroom>

9491 2002-04-15 Michael Hope <michaelh AT vroom>
9493 * device/lib/z80/printf.c (sprintf): Added.
9495 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
9497 * src/z80/peeph.def: Added transpose redundent load rule.
9499 * src/z80/main.c: Added force callee saves for jaune.
9501 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9503 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9505 2002-03-28 Johan Knol <johan AT balder>
9507 * src/SDCCval.c: fixed bug #532436
9509 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9511 Added "char *Processor" field to the port structure.
9514 Added -p option. Allows port dependent processor to be specified.
9517 Initialized the new field char *Processor field to NULL in all ports
9520 Compiler generated registers for interrupt context saving
9521 were not getting allocated.
9523 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9526 Fixed left shift. Will promote the left side of a left shift
9527 if a) left shifting more than size of operand or b) when assigned
9528 to something size > size of left side
9530 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9532 tons of changes. Register allocation has been
9533 rewritten. Added customization for the various PICs. Flow
9534 analysis is restructured. ...
9540 Added. device.c is a PIC port hack to accomodate variations
9543 2002-03-13 Michael Hope <michaelh AT vroom>
9545 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9547 2002-03-04 johanknol <johanknol AT manik>
9549 * /src/SDCCval.c: fixed
9551 const unsigned char arr[][2] = { { 0, 1 } };
