2267 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2268 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2269 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2270 always available in leading double underscore form. The C99 support is
2271 mostly missing, but it's a start.
2272 * support/regression/tests/bug-227710.c: fixed nonconforming use of

2353 * device/lib/printf_large.c: removed inline assembly for portability and
2354 readability. Use printf_fast if speed or size are more important.
2355 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2356 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2358 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2360 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2361 prevent compiler warning
2363 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2365 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2366 moved to level 0 and declared as static. Also they are explicit
2367 placed in access bank. This was necessery because some times they
2368 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2369 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2370 optimizations. Currently only compare to unsigned char is implemented,
2371 * src/pic16/gen.c: added fReturnIdx array,
2372 * (struct resolvedIfx) is moved to gen.h and made public,
2373 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2374 * (aopForSym): added an optimization to directly store in stack of
2375 the operand of a SEND iCode,
2376 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2377 but as registers instead (AOP_REG) using the fReturnIdx array,
2378 * (pic16_freeAsmop): remove the freed register from the
2379 _G.sregsAlloc field,
2380 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2381 a compare of 'WREG',
2382 * (pic16_popGetTempRegCond): changed function prototype, now
2383 function takes also a bitVector argument v which holds the current
2384 set of registers that are allocated for stack access by aopForSym,
2385 registers allocated in aopForSym for accessing stack symbols are not
2386 any more part of the functions usedRegs field,
2387 * (genCall): some times aopOp is called for a stack variable to be
2388 send, aopForSym might perform the push, if this is true make sure
2389 that genCall doesn't push the variable twice by testing _G.resDirect,
2390 * (genFunction): changed testing for unspecified interrupt number
2391 from 256 to INTNO_UNSPEC,
2392 * modified selection scheme of frame pointer generation. Previously
2393 if function did use local registers a frame pointer was generated,
2394 now a frame pointer is generated only if function has arguments
2395 (that need PLUSW2 register access), or has stack arguments, or the
2396 compiler is not instructed to omit the frame pointer,
2397 * (genEndFunction): before restoring local registers that were saved
2398 in the function preamble, also restore the registers that *might*
2399 have been allocated for stack access,
2400 * (genRet): removed some old comments,
2401 * (genCmp, the active (RN's) version): added a call to the
2402 pic16_genCmp_special function to perform the compare with a more
2403 robust and optimized way,
2404 * (genInline): a feature has been added in inline code generation,
2405 which allows a wildcard variable substitution when writing inline
2406 assembly. Code is incomplete and experimental therefore undocumented,
2407 * (genCast): changed order of aopOp for result and right to allow
2408 aopForSym to directly load the result if possible,
2409 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2410 perform an optimized compare on some selected special occasions,
2411 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2412 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2413 generate an IVT any more,
2414 * src/pic16/main.c (pic16_optionsTable): added command line option
2416 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2417 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2419 * src/pic16/NOTES: Raphael Neider added in list of active developers
2420 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2421 jumptable_end to prevent bug #,
2422 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2423 inCond and outCond fields,
2424 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2425 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2426 turn off register spilling,
2427 * (packRegsForOneUse): synced with other ports' versions although it
2428 is not used currently,
2429 * (pic16_packRegisters): added an optimization while reading
2430 structure bitfields, some registers may be saved (malloc code is
2431 decreased by 80 bytes)
2433 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2435 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2436 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2437 this can be optimized more?
2439 2005-03-10 Raphael Neider <rneider AT web.de>
2441 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2442 genNearPointerGet): (hopefully) fixed access to bitfields via
2443 pointers (p->bitN = x; and x = p->bitN; failed)

3077 Adding support for replacing ljmps with sjmps in jumptables
3078 generated for switch statements. For now you need to set the
3079 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3080 Now 4 algorithms for mcs51 jumptable generation are used:
3081 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3082 addresses loaded pc-relative for up to 112 cases and stack-pushing
3083 target addresses loaded with offset from dptr for up to 256 cases.

3110 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3111 to call when a stack overflow occurs,
3112 * (malloc.h): added CVS Id tag,
3113 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3115 * added libc directory. The current version of LibC contains string
3116 functions, ctype functions and macros and some functions of the
3117 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3118 be extensively tested in the future. Standard disclaimer here.
3119 Library is not automatically build yet. But one can build it by
3120 invoking 'make' inside the libc directory.
3121 * added ADC library under libio. Preliminary version yet.
3123 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

3130 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3131 * (pic16_storeForReturn): optimized return of 0,
3132 * (genCmp): experimental code for new genCmp which uses PIC18's
3133 special compare&skip instructions. Initial tests fail some times
3134 with variables grater than 1 byte in size, so new code is disabled,
3135 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3137 * (genCast): began a fix to optimize the casting of a bit to another
3138 bit, now assigning a bitfield to another bitfield will fail, sorry,
3139 * src/pic16/main.c: disabled the use of lr-support feature,
3140 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
3141 * added some function prototypes, added function _debugf prototype,

3143 bits with offset (case PO_GPR_BIT),
3144 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3146 * (isBankInstruction): modified to return 0 for no banking instruction,
3147 and 1 for banking instruction,
3148 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3149 caused stop processing pCodes after a inline assembly block,
3150 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3151 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3152 registers when it shouldn't,
3153 * src/pic16/ralloc.c (allocReg): add preliminary support for
3154 supporting a limited set of temporary registers,
3156 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3158 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3159 genDataPointerSet): ensure assignments always copy in MSB to LSB
3161 (loadRegFromAop): recognize CLRH optimization,
3162 (genFunction): optimize RECEIVE iCodes in reentrant functions
3164 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3166 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6161 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6163 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6164 loaded with the linker search paths (-L arguments) and the libraries
6165 to be linked with the current source (-l arguments). Changes
6166 currently will affect only the pic16 port.
6167 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6168 include path the port specific paths and port specific libraries,
6169 * gplink command now contains the $3 argument,
6170 * src/pic16/device.h,
6171 * src/pic16/device.c,: structure PIC_device is made public and
6172 renamed to PIC16_device, the same for variable Pics which is renamed
6173 to Pics16. Updated all references to them.
6174 * src/pic16/glue.c (pic16glue): corrected bug with code
6175 initialization which bypassed the variable initializations block.

6185 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
6187 Documenting changes from previous commits.
6188 * configure.in (version 1.56),
6189 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6190 when generating output files to configure the pic16 library,
6191 but now I've commented it out, since gputils aren't installed in the
6192 SF compile farm, so library won't compile
6194 * device/lib/Makefile.in (version 1.56): initially I've added in
6195 target 'all' the prerequestive 'model-pic16' so it compiled the
6196 pic16 library, but now I've commented it out for the same reasons
6198 * added targets 'model-pic16' and 'objects-pic16' to compile the
6200 * added target 'port-specific-objects-pic16' to handle the
6201 generated libraries and copy them into the build/ directory
6202 * added target 'clean-intermediate-pic16' to clean intermediate
6203 files into pic16 directory
6204 * in target 'installdirs' added line to create directory pic16 in
6205 the installation path
6207 * device/include/Makefile.in (version 1.11): in target 'install'
6208 added lines to copy all header files to installation path,
6209 * in target 'installdirs' added line create directory for pic16
6210 headers in the installation path

6225 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6226 option so that it actually works. Made it specific to the z80, since
6227 the gbz80 doesn't have these kinds of I/O ports.
6229 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6231 * device/include/z180.h,

6244 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6246 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
6247 changed interrupt vector table generation to only emit declared vectors.
6248 * device/include/Makefile.in: added missing backslash
6249 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
6251 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6253 Mainly changes to support compilation of the device libraries
6254 * src/pic16/device.c: stack is allocated via symbol and not
6255 via literal number. The symbol is placed in the corresponding
6256 position of the data ram
6257 * (pic16_dump_section): relocatable and absolute uninitialized
6258 data are now emitted in sorted order to reduce section naming,
6259 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6260 weren't marked as being in the access bank,
6262 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6264 Added portion of GNU PIC Library under the directory
6265 device/include/pic16 and device/lib/pic16. These files
6266 contain the declarations of SFRs for the PIC18Fxx2 devices.
6267 The directory is initialized via configure from toplevel.
6269 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6271 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
6272 the spilllocations to be compared correctly
6274 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
6276 * src/SDCCast.c (decorateType): fixed bug introduced today
6278 2004-01-12 Borut Razem <borut.razem AT siol.net>
6280 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

6283 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
6285 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
6286 in simpler and even better code
6288 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
6290 * src/SDCCicode.c (operandOperation): fixed bug #874819

6294 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6296 * doc/sdccman.lyx: Moved and added some sections, small changes
6297 all over. Telling LaTeX to be less strict with word spacing
6298 to better keep the right margin. Changed some notes about
6299 maintainance of the ports in section 3.2.1 - is it OK like this?
6301 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
6303 SDCC source changes:
6304 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

6337 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
6338 UPPER for immediate operands,
6339 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6341 * src/pic16/peeph.def: all peepholes with movff are commented out,
6342 because there is a problem in the pcode peep optimizer,
6343 * src/pic16/ralloc.c: the register allocator can now reuse local
6344 function symbols for another function. This saves register usage.
6345 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6347 Added file src/pic16/NOTES with information about program writing on
6348 the current port version.

6357 * src/SDCCmain.c : fixed #872250: -l command line defined library
6358 files are scanned before standard library files
6360 2004-01-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6377 gen51Code): more efficient parameter receive for --model-large
6380 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6383 * src/z80/main.c: added missed needLinkerScript flags (more than
6384 one port structure defined in these file)
6385 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

6401 needLinkerScript flag
6403 * src/pic16/gen.c (genAddrOf): fixed bug #863624
6404 * src/pic/glue.c: added variable udata_section_name to
6405 override default uninitialized data segment definition for
6406 devices only with SHAREBANK memory (reported from Erik Epetrich)
6407 * (pic14emitOverlay): modified to emit a commented overlay segment
6408 directive when no overlay data exist
6409 * (picglue): modified to emit uninitialized data segment
6410 according to udata_section_name

6415 arguments via -W option
6416 * src/pic16/main.c: added $l in _asmCmd, changed extension for
6417 object file from '.rel' to '.o' in port->linker structure,
6418 changed size of fptr from 2 to 3 in port structure
6420 2004-01-07 Borut Razem <borut.razem AT siol.net>
6422 * support/scripts/sdcc.nsi: update PATH
6423 * support/scripts/sdcc.ico: craeted
6425 2004-01-07 Bernhard Held <bernhard AT bernhardheld.de>
6427 * device/include/Makefile.in: fix install
6428 * doc/Makefile: fix install
6430 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6432 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
6434 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
6435 how the function variable allocation summary is displayed; also
6436 include information about variables allocated to the overlay
6439 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6441 * as/mcs51/lkmain.c: Help about -Y option

6453 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6455 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6456 (default behaviour).
6458 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6460 A python script to validate compiler diagnostic messages. It can be
6461 used to verify that sdcc complains about bad c source code and
6462 gives a good location of the error.
6463 * support/valdiag/Makefile,
6464 * support/valdiag/valdiag.py,
6465 * support/valdiag/tests/*
6467 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6469 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

6478 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6480 * src/common.h: added ifndef/define/endif macros
6481 around the header file.
6482 Bug reported from Jesus Calvino-Fraga
6484 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6486 * sdcc.spec: updated
6487 * device/include/Makefile.in: don't install CVS directories
6488 * device/lib/Makefile.in: added removal of CVS directories after install
6489 * doc/Makefile: fixed install, added local_icons
6490 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6491 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6492 * src/ds390/gen.c (genRightShift): fixed bug #870788
6493 * src/SDCCast.c (decorateType): fixed bug #870781
6495 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6497 PIC16 port related changes:
6498 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6499 added variable stackPos,
6501 * gen.c: genCall, assignResultValue: added support for
6502 pushing/retrieving function parameters to/from stack,
6503 genFunction,genEndFunction: setup stack frame for the
6505 genAddrOf: will be changed according to bug 863624
6507 * added files genutils.c and genutils.h which contain gen*
6508 debugged and optimised functions extracted from gen.c
6510 * glue.c: added variable 'externs' which holds extern symbols,
6511 pic16emitRegularMap: is modified to properly handle relocatable
6512 symbols under the new scheme,
6513 pic16createInterruptVect: is modified
6514 pic16printPublics: is modified to emit 'global' assembler directives,
6515 added pic16_printExterns to print extern symbols,
6516 pic16glue: initializes stack/frame pointer in the beginning of
6517 the assembly output. Temporary hack, will be corrected later,
6518 because gplink yet does not support stack and SDCC does not
6519 yet support a type of crt0.o object to create the final binary.
6521 * Removed many lines that contain 8051 legacy code.
6522 * The code is finally placed under a 'code' directive.
6523 * Added port specific options.
6525 * _process_pragma: simplified since now we do not need *special*
6526 include file to define SFR registers. But a separate header
6527 will be needed. This will be developed later.
6528 * _pic16_parseOptions: added, parses port specific options:
6529 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6530 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6531 --preplace-udata-with=
6533 * _pic16_setDefaultOptions: modified to initialize section names,
6534 but hack is temporarly out of order since it needs improvement.
6535 * _pic16_genAssemblerPreamble: configuration words are emitted by
6536 their address instead of their name. This part is incomplete and
6537 supports only the 18Fxx2 devices. Other devices will emit an error
6538 during assembly since they do not contain the same set of config
6540 * _pic16_genIVT: is modified,
6542 * pcode.c: added definitions for some hardware registers that are needed
6544 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6545 All PCI entries are updated. Now LFSR is supported.
6546 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6547 * added pic16_newpCodeOpLit2 to support instructions with
6548 two literal arguments
6549 * pic16_pCode2str: corrected code that emits assembler instructions
6550 with two literal operands and those that have an access bit modifier
6551 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6552 this fixes a bug which caused some labels to be lost, when an
6553 assembler directive was added, i.e. banksel,
6554 * pic16_FixRegisterBanking: improved logic that causes the insertion
6556 * InlineFunction: functions that are called once, are not any more
6557 inlined. This can be a port option in the future,
6559 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6561 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6562 hold the corresponding uninitialized symbols,
6563 * pic16_allocProcessorRegister: registers have explicit marked the
6565 * pic16_allocInternalRegister: registers are explicit marked as
6567 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6568 processing list, so bit registers were lost,
6571 * ralloc.h: added field 'accessBank' and original symbol operand
6572 in register definition,
6573 * removed the field isMapped from register definition,
6575 ** Several functions have been removed from various sources:
6576 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6577 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6578 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6579 pic16_assignRelocatableRegisters
6581 ** others have been introduced:
6582 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6583 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6585 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6587 * support/scripts/inc2h.pl: changed definition of BIT_AT
6588 to emit 'sbit at' instead of 'bit at'. This was a request.
6590 PIC16 port related preliminary changes:
6591 * gen.c: prefixed function popRegFromString with
6592 pic16_ and all references to it corrected
6593 * pcode.c: all pic16_pc_* hardware registers prefixed
6594 with underscore (_),
6595 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6596 * ralloc.c: newReg(): when register is REG_SFR then
6597 set address to rIdx,
6598 pic16_allocProcessorRegister(): marks register wasUsed=0
6599 pic16_writeUsedRegs(): added a call to assign processor
6600 registers via pic16_assignFixedRegisters
6602 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6604 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6605 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6606 variables in unused register banks. Also the SSEG is placed
6607 wherever there is enough space for it, and IDATA can be anywhere
6608 in internal RAM. For now compile using -Wl-Y[stack_size].
6609 The mem file is different for this option as well, since it

7608 iCode properly now. Use getSize instead of nRegs since a & b
7609 aren't part of the nRegs tally.
7611 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
7613 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
7614 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
7615 before instructions that use the _STATUS register
7617 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
7619 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7620 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7621 fetching of the pointer
7622 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7623 copied from genNearPointerSet()
7624 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7625 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7626 If they pop r0/r1 they must be called in the opposite order than aopOp().
7627 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7628 (resp. --stack-auto), prepared for --xstack

7639 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7641 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7642 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7643 type for bits was changed. It resulted in bit variables becoming
7644 global, which is not permitted in PIC 14 assembly output.
7646 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7648 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7650 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7652 Z80 and MCS51 linkers complaint if a public symbol is defined

7661 A few small changes that speed up the peephole optimizer.
7665 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7667 Try to make the peephole optimizer smarter by maintaining
7668 an association between the assembly source code and the
7669 iCodes that originated them. Put this information to use
7670 with a new peephole rule condition "notVolatile" so that
7671 the rules can be aggressive yet still safe.
7676 * src/mcs51/peeph.def
7678 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7682 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7683 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7684 if the left or right operand symbols have the accuse flag set.
7686 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7688 Changed the type of the result of the ! (NOT) operator to char;
7689 previously it returned the same type as the source. This allows
7690 us to eliminate all the genFloatNot functions (all of its target
7691 implementations were very buggy) since !float can use the same
7694 * src/SDCCicode.c (ast2iCode): ! returns char

7703 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7704 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7705 during interrupts. Ensure WSAVE is located at a shared bank address.
7706 2. Fixed page selection in some places
7707 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7708 the registers name strings.
7709 4. Fixed "signed / unsigned compare" compiler warnings.
7710 5. The PIC port manages its own allocation of the general purpose
7711 registers, but makes no attempt to reuse them. As a result when
7712 compiling it soon runs out of general purpose registers. Some
7713 additional code was added to the files pcode.c and device.c to walk
7714 through the function call tree and rename the registers so that they
7724 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7725 genPlus() & genMinus() when the result is the same as left or right

7731 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7733 Made bitfield a distinct type from bit so that bitfields
7734 convert as per ANSI C and bits retain their traditional
7735 boolean style behaviour. Implemented bitfield support in
7743 * src/ds390/gen.c: bit v bitfield split
7744 * src/z80/gen.c: New support for bitfields
7745 * support/regression/tests/bitfields.c: reenabled z80,
7748 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7750 Rules 246.x, 247.x relate to bitfields, the others speed up
7751 access to xdata mapped I/O devices.
7753 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7755 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7757 Cleaned up genPackBits and genUnpackBits and added two helper
7758 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7759 for literal assignments in genPackBits (thanks to Frieder for
7765 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7767 Fixed bug #748310 (pointer to function type mishandled when the
7768 function name is omitted). Also fixed a SIGSEGV when a function
7769 attribute (reentrant, etc) is used on a non-function or on a
7770 function but misplaced before the parameter list.
7772 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7774 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7775 * support/Util/SDCCerr.h,

7797 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7799 Made the constant following the "interrupt" keyword optional. If
7800 omitted, the function will not automatically be given an entry
7801 in the interrupt vector table (similar to #pragma NOIV, but
7802 less syntacticly kludgy). The interrupt number is also now
7803 range checked. Also fixed a bug in the high order bit example

7817 * src/SDCCicode.c (operandOperation): rewritten some ops
7818 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7819 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7821 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7822 be re-activated by defining REDUCE_LITERALS)
7823 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7824 unsigned, but are signed by default
7825 * src/SDCCval.c (constVal): rearranged
7826 * src/SDCCval.c (valMod): preliminary fix
7827 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8279 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8280 the regression tests I'm not brave enough to enable 245.b, 245.c
8281 * doc/sdccman.lyx: added latex preamble for hyperref package.
8282 Using pdflatex this will give you a hyperlinked pdf file with
8283 bookmarks. (prepend '%' before /usepackage if this breaks something)

8297 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
8299 Applied patch from bug 737905 (renamed yylineo to mylineno):
8306 * src/pic16/pcode.c: Cleaned warnings
8307 * src/pic16/pcodeflow.c: Cleaned warnings
8308 * src/pic16/pcoderegs.c: Cleaned warnings

8321 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8323 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8324 it can be defined with CFLAGS when running configure
8325 * src/SDCCmain.c: fixed compiling + linking with object files
8327 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

8330 added --disable-pic16-port
8331 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8332 * src/SDCCmain.c: linkOptions is changed to set *,
8333 added if/endif conditional macros to remove options help
8334 messages from optionsTable when a port is not configured, added
8335 support for the PIc16 port in the ports table, when executing
8336 the compiler with no port specified on command line, a default
8337 port is selected with the new macro DEFAULT_PORT which is
8338 defined in port.h, in setDefaultOptions() linkOptions is removed
8339 from initialization assignment, since now it is a set,
8340 parseCmdLine uses setParseWithComma for linkOptions, in
8341 linkEdit() linkOptions are accessed with new function indexSet()
8342 which returns the i'th item of a set variable. See SDCCset.c, in
8343 linkEdit() when calling buildCmdLine(), added linkOptions as
8344 last argument. Now users can pass arguments to gplink via the
8345 -Wl option, main() uses pic16glue() to glue up pic16 programs

8357 * src/pic16/glue.c: commented out some error producing lines
8358 * src/pic16/main.c: __config directives are commented out to stop
8359 gpasm complaining and test the linkage with gplink, _linkCmd and
8360 _asmCmd changed to be more gplink and gpasm friendly
8361 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8362 produced an error when parsed, peep rule 12 is added to utilize
8363 movff, but it is commented out since the pCode does not support
8364 yet a command with 2 address arguments
8366 2003-05-18 <johan AT balder>
8368 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8369 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8370 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

8393 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
8395 2003-05-11 Borut Razem <borut.razem AT siol.net>
8397 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8398 the path of bin directory, so that PATH is the only env. variable, which has to be set
8399 in case of standard installation.
8400 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9429 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9431 * in \sdcc\as\mcs51\ changed these files in order to create an
9432 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9433 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9434 following files to include the previous two files: aslink.dsp,
9435 Makefile.aslink, Makefile.bcc, and Makefile.in.
9437 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9438 .adb instead of .cdb
9440 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9442 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9443 value from option --iram-size.
9445 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9447 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9450 2002-09-18 <wiml AT hhhh.org>
9452 * SDCClrange.h: exposed setFromRange() and setToRange()
9453 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9454 packRegsForAccUse() (bug 542397)
9455 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9456 multiple times and emitting the fetch operations more than once
9457 added aopGetUsesAcc() function to allow binary operators to
9458 fetch their operands in the correct order; made genMinus() emit
9459 compact code for X = LITERAL - Y
9461 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9462 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9463 sprintf() in line 1267.
9465 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9466 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9469 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9470 Changes to aslink (All the changes are marked with 'JCF'):
9472 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9475 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9476 area BSEG. Also moves, if possible, the DATA area down into the internal
9477 ram so more space is available.
9479 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9482 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9483 not bytes. Function summary() which creates a memory usage summary
9484 file with extension .mem. Reports of overlaping stack and small stack
9485 size. If the space for the stack is less than 16 bytes aslink trows a
9488 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9489 the 8051. Option 'y' for memory summary output file.
9491 Changes to sdcc (All the changes are marked with 'JCF'):
9493 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9495 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9496 overlaying area for it (uses RegBankUsed[4]).
9498 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9499 bank zero as used by default. By default aslink locates the stack
9500 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9501 the creation of the .mem file. Delegates the allocation of data area
9502 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9503 the begining of the stack area to aslink.
9505 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9506 glue() in SDCCglue.c creates an area for it.
9508 2002-09-03 Borut Razem <borut.razem AT siol.net>
9509 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9510 sdcc/src/pic/glue.c:
9511 introduced atexit() handler for teporay files removal in case of
9512 errors, assertions, ...
9514 2002-08-29 Borut Razem <borut.razem AT siol.net>
9515 * sdcc/support/cpp2/auto-host_vc_in.h:
9516 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9517 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9518 Maybe there is a similar problem with BORLANDC? It should be checked!
9520 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9521 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9522 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9523 was not executed, and the compiler (cl) launched a warning:
9524 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9526 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

9530 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9532 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9533 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9534 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9535 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9536 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9537 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9538 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9539 - added Release configuration in VS projects
9540 - review of compiler an linker options
9541 - VC .exe files are generated in bin_vc directory, not to interfere
9542 with binaries generated from other projects (cygwin, mingw, bcc ...)
9544 * sdcc/src/yacc.dsp: added
9546 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9547 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9548 and insert the version number definitions from .version
9550 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9552 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

9561 2002-08-11 Borut Razem <borut.razem AT siol.net>
9562 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9564 2002-08-10 Borut Razem <borut.razem AT siol.net>
9565 * src/SDCCmain.c (main):
9566 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9567 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9568 The consequence was that some temporary files were not removed.
9571 unification of code in functions tempfilename() and tempfile():
9572 function tempnam() is defined in Visual Studio 6.0 and .NET
9574 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9576 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9577 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9578 - removed compiler command line option /WX: Treats all warnings as errors
9579 - update a list of source files, included into the project
9581 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9582 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9583 changed project type to Generic Project so that can be correcly converted to VS.NET project
9585 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9587 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

9591 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9592 added return 0 statements after assert() to make compiler happy
9594 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9595 added newline in the def file to keep MSC compiler satisfied
9597 * sdcc/src/z80/gen.c:
9598 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9599 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9600 - solved MSC error in function aopDump()
9602 * sdcc_vc.h: define PREFIX as "\\sdcc"
9604 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

9653 Added -p option. Allows port dependent processor to be specified.
9656 Initialized the new field char *Processor field to NULL in all ports
9659 Compiler generated registers for interrupt context saving
9660 were not getting allocated.
9662 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9665 Fixed left shift. Will promote the left side of a left shift
9666 if a) left shifting more than size of operand or b) when assigned
9667 to something size > size of left side
9669 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9671 tons of changes. Register allocation has been
9672 rewritten. Added customization for the various PICs. Flow

9777 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9779 * sdcc/src/SDCCloop.c:
9780 Previous fix was not good. basic blocks that have "break" or "return" are
9781 not really partof a loop , but live ranges used in these blocks should
9782 be live thru the entire loop, so set partOfLoop but don't add them to
9785 2002-02-21 <johan AT FRIJA>
