2274 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2275 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2276 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2277 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2278 always available in leading double underscore form. The C99 support is
2279 mostly missing, but it's a start.
2280 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2281 reserved identifier "__data".
2283 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

2359 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2361 * device/lib/printf_large.c: removed inline assembly for portability and
2362 readability. Use printf_fast if speed or size are more important.
2363 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2364 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2366 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2368 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2369 prevent compiler warning
2371 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2373 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2374 moved to level 0 and declared as static. Also they are explicit
2375 placed in access bank. This was necessery because some times they
2376 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2377 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2378 optimizations. Currently only compare to unsigned char is implemented,
2379 * src/pic16/gen.c: added fReturnIdx array,
2380 * (struct resolvedIfx) is moved to gen.h and made public,
2381 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2382 * (aopForSym): added an optimization to directly store in stack of
2383 the operand of a SEND iCode,
2384 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2385 but as registers instead (AOP_REG) using the fReturnIdx array,
2386 * (pic16_freeAsmop): remove the freed register from the
2387 _G.sregsAlloc field,
2388 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2389 a compare of 'WREG',
2390 * (pic16_popGetTempRegCond): changed function prototype, now
2391 function takes also a bitVector argument v which holds the current
2392 set of registers that are allocated for stack access by aopForSym,
2393 registers allocated in aopForSym for accessing stack symbols are not
2394 any more part of the functions usedRegs field,
2395 * (genCall): some times aopOp is called for a stack variable to be
2396 send, aopForSym might perform the push, if this is true make sure
2397 that genCall doesn't push the variable twice by testing _G.resDirect,
2398 * (genFunction): changed testing for unspecified interrupt number
2399 from 256 to INTNO_UNSPEC,
2400 * modified selection scheme of frame pointer generation. Previously
2401 if function did use local registers a frame pointer was generated,
2402 now a frame pointer is generated only if function has arguments
2403 (that need PLUSW2 register access), or has stack arguments, or the
2404 compiler is not instructed to omit the frame pointer,
2405 * (genEndFunction): before restoring local registers that were saved
2406 in the function preamble, also restore the registers that *might*
2407 have been allocated for stack access,
2408 * (genRet): removed some old comments,
2409 * (genCmp, the active (RN's) version): added a call to the
2410 pic16_genCmp_special function to perform the compare with a more
2411 robust and optimized way,
2412 * (genInline): a feature has been added in inline code generation,
2413 which allows a wildcard variable substitution when writing inline
2414 assembly. Code is incomplete and experimental therefore undocumented,
2415 * (genCast): changed order of aopOp for result and right to allow
2416 aopForSym to directly load the result if possible,
2417 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2418 perform an optimized compare on some selected special occasions,
2419 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2420 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2421 generate an IVT any more,
2422 * src/pic16/main.c (pic16_optionsTable): added command line option
2424 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2425 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2427 * src/pic16/NOTES: Raphael Neider added in list of active developers
2428 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2429 jumptable_end to prevent bug #,
2430 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2431 inCond and outCond fields,
2432 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2433 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2434 turn off register spilling,
2435 * (packRegsForOneUse): synced with other ports' versions although it
2436 is not used currently,
2437 * (pic16_packRegisters): added an optimization while reading
2438 structure bitfields, some registers may be saved (malloc code is
2439 decreased by 80 bytes)
2441 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2443 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2444 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2445 this can be optimized more?
2447 2005-03-10 Raphael Neider <rneider AT web.de>
2449 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2450 genNearPointerGet): (hopefully) fixed access to bitfields via
2451 pointers (p->bitN = x; and x = p->bitN; failed)

3085 Adding support for replacing ljmps with sjmps in jumptables
3086 generated for switch statements. For now you need to set the
3087 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3088 Now 4 algorithms for mcs51 jumptable generation are used:
3089 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3090 addresses loaded pc-relative for up to 112 cases and stack-pushing
3091 target addresses loaded with offset from dptr for up to 256 cases.

3118 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
3119 to call when a stack overflow occurs,
3120 * (malloc.h): added CVS Id tag,
3121 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3123 * added libc directory. The current version of LibC contains string
3124 functions, ctype functions and macros and some functions of the
3125 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3126 be extensively tested in the future. Standard disclaimer here.
3127 Library is not automatically build yet. But one can build it by
3128 invoking 'make' inside the libc directory.
3129 * added ADC library under libio. Preliminary version yet.
3131 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

3138 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3139 * (pic16_storeForReturn): optimized return of 0,
3140 * (genCmp): experimental code for new genCmp which uses PIC18's
3141 special compare&skip instructions. Initial tests fail some times
3142 with variables grater than 1 byte in size, so new code is disabled,
3143 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3145 * (genCast): began a fix to optimize the casting of a bit to another
3146 bit, now assigning a bitfield to another bitfield will fail, sorry,
3147 * src/pic16/main.c: disabled the use of lr-support feature,
3148 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3151 bits with offset (case PO_GPR_BIT),
3152 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3154 * (isBankInstruction): modified to return 0 for no banking instruction,
3155 and 1 for banking instruction,
3156 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3157 caused stop processing pCodes after a inline assembly block,
3158 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3159 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3160 registers when it shouldn't,
3161 * src/pic16/ralloc.c (allocReg): add preliminary support for
3162 supporting a limited set of temporary registers,
3164 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3166 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3167 genDataPointerSet): ensure assignments always copy in MSB to LSB
3169 (loadRegFromAop): recognize CLRH optimization,
3170 (genFunction): optimize RECEIVE iCodes in reentrant functions
3172 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3174 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6124 code / RAM are in the same page / bank. This means the linker can
6125 safely allocate code/RAM of separate ASM files to different pages/banks.
6126 * doc/sdccman.lyx: added Slade's tips
6127 * src/mcs51/peeph.def: fixed bug #880768

6139 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
6140 strtof is not part of C89 and isn't included with Mac OS X.
6142 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6144 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,
6145 shiftL2Left2Result): fixed bug #879326
6146 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY

6169 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6171 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6172 loaded with the linker search paths (-L arguments) and the libraries
6173 to be linked with the current source (-l arguments). Changes
6174 currently will affect only the pic16 port.
6175 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6176 include path the port specific paths and port specific libraries,
6177 * gplink command now contains the $3 argument,
6178 * src/pic16/device.h,
6179 * src/pic16/device.c,: structure PIC_device is made public and
6180 renamed to PIC16_device, the same for variable Pics which is renamed
6181 to Pics16. Updated all references to them.

6193 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
6195 Documenting changes from previous commits.
6196 * configure.in (version 1.56),
6197 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6198 when generating output files to configure the pic16 library,
6199 but now I've commented it out, since gputils aren't installed in the
6200 SF compile farm, so library won't compile
6202 * device/lib/Makefile.in (version 1.56): initially I've added in
6203 target 'all' the prerequestive 'model-pic16' so it compiled the
6204 pic16 library, but now I've commented it out for the same reasons
6206 * added targets 'model-pic16' and 'objects-pic16' to compile the
6208 * added target 'port-specific-objects-pic16' to handle the
6209 generated libraries and copy them into the build/ directory
6210 * added target 'clean-intermediate-pic16' to clean intermediate
6211 files into pic16 directory
6212 * in target 'installdirs' added line to create directory pic16 in
6213 the installation path
6215 * device/include/Makefile.in (version 1.11): in target 'install'
6216 added lines to copy all header files to installation path,
6217 * in target 'installdirs' added line create directory for pic16
6218 headers in the installation path

6233 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6234 option so that it actually works. Made it specific to the z80, since
6235 the gbz80 doesn't have these kinds of I/O ports.
6237 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6239 * device/include/z180.h,

6252 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6254 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
6255 changed interrupt vector table generation to only emit declared vectors.

6261 Mainly changes to support compilation of the device libraries
6262 * src/pic16/device.c: stack is allocated via symbol and not
6263 via literal number. The symbol is placed in the corresponding
6264 position of the data ram
6265 * (pic16_dump_section): relocatable and absolute uninitialized
6266 data are now emitted in sorted order to reduce section naming,
6267 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6268 weren't marked as being in the access bank,
6270 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6272 Added portion of GNU PIC Library under the directory
6273 device/include/pic16 and device/lib/pic16. These files
6274 contain the declarations of SFRs for the PIC18Fxx2 devices.
6275 The directory is initialized via configure from toplevel.
6277 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6279 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
6280 the spilllocations to be compared correctly

6291 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
6293 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
6294 in simpler and even better code
6296 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
6298 * src/SDCCicode.c (operandOperation): fixed bug #874819

6304 * doc/sdccman.lyx: Moved and added some sections, small changes
6305 all over. Telling LaTeX to be less strict with word spacing
6306 to better keep the right margin. Changed some notes about
6307 maintainance of the ports in section 3.2.1 - is it OK like this?
6309 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6347 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6349 * src/pic16/peeph.def: all peepholes with movff are commented out,
6350 because there is a problem in the pcode peep optimizer,
6351 * src/pic16/ralloc.c: the register allocator can now reuse local

6466 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6468 A python script to validate compiler diagnostic messages. It can be
6469 used to verify that sdcc complains about bad c source code and
6470 gives a good location of the error.
6471 * support/valdiag/Makefile,
6472 * support/valdiag/valdiag.py,
6473 * support/valdiag/tests/*
6475 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6490 Bug reported from Jesus Calvino-Fraga
6492 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6494 * sdcc.spec: updated
6495 * device/include/Makefile.in: don't install CVS directories

6500 * src/ds390/gen.c (genRightShift): fixed bug #870788
6501 * src/SDCCast.c (decorateType): fixed bug #870781
6503 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6505 PIC16 port related changes:
6506 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6507 added variable stackPos,
6509 * gen.c: genCall, assignResultValue: added support for
6510 pushing/retrieving function parameters to/from stack,
6511 genFunction,genEndFunction: setup stack frame for the
6513 genAddrOf: will be changed according to bug 863624
6515 * added files genutils.c and genutils.h which contain gen*
6516 debugged and optimised functions extracted from gen.c
6518 * glue.c: added variable 'externs' which holds extern symbols,
6519 pic16emitRegularMap: is modified to properly handle relocatable
6520 symbols under the new scheme,
6521 pic16createInterruptVect: is modified
6522 pic16printPublics: is modified to emit 'global' assembler directives,
6523 added pic16_printExterns to print extern symbols,
6524 pic16glue: initializes stack/frame pointer in the beginning of
6525 the assembly output. Temporary hack, will be corrected later,
6526 because gplink yet does not support stack and SDCC does not
6527 yet support a type of crt0.o object to create the final binary.
6529 * Removed many lines that contain 8051 legacy code.
6530 * The code is finally placed under a 'code' directive.
6531 * Added port specific options.
6533 * _process_pragma: simplified since now we do not need *special*
6534 include file to define SFR registers. But a separate header
6535 will be needed. This will be developed later.
6536 * _pic16_parseOptions: added, parses port specific options:
6537 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6538 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6539 --preplace-udata-with=
6541 * _pic16_setDefaultOptions: modified to initialize section names,
6542 but hack is temporarly out of order since it needs improvement.
6543 * _pic16_genAssemblerPreamble: configuration words are emitted by
6544 their address instead of their name. This part is incomplete and
6545 supports only the 18Fxx2 devices. Other devices will emit an error
6546 during assembly since they do not contain the same set of config
6548 * _pic16_genIVT: is modified,
6550 * pcode.c: added definitions for some hardware registers that are needed
6552 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6553 All PCI entries are updated. Now LFSR is supported.
6554 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6555 * added pic16_newpCodeOpLit2 to support instructions with
6556 two literal arguments
6557 * pic16_pCode2str: corrected code that emits assembler instructions
6558 with two literal operands and those that have an access bit modifier
6559 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6560 this fixes a bug which caused some labels to be lost, when an
6561 assembler directive was added, i.e. banksel,
6562 * pic16_FixRegisterBanking: improved logic that causes the insertion
6564 * InlineFunction: functions that are called once, are not any more
6565 inlined. This can be a port option in the future,
6567 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6569 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6570 hold the corresponding uninitialized symbols,
6571 * pic16_allocProcessorRegister: registers have explicit marked the
6573 * pic16_allocInternalRegister: registers are explicit marked as
6575 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6576 processing list, so bit registers were lost,
6579 * ralloc.h: added field 'accessBank' and original symbol operand
6580 in register definition,
6581 * removed the field isMapped from register definition,
6583 ** Several functions have been removed from various sources:
6584 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6585 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6586 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6587 pic16_assignRelocatableRegisters
6589 ** others have been introduced:
6590 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6591 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6593 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6595 * support/scripts/inc2h.pl: changed definition of BIT_AT
6596 to emit 'sbit at' instead of 'bit at'. This was a request.
6598 PIC16 port related preliminary changes:
6599 * gen.c: prefixed function popRegFromString with
6600 pic16_ and all references to it corrected
6601 * pcode.c: all pic16_pc_* hardware registers prefixed
6602 with underscore (_),
6603 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6604 * ralloc.c: newReg(): when register is REG_SFR then
6605 set address to rIdx,
6606 pic16_allocProcessorRegister(): marks register wasUsed=0
6607 pic16_writeUsedRegs(): added a call to assign processor
6608 registers via pic16_assignFixedRegisters
6610 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6612 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6613 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6614 variables in unused register banks. Also the SSEG is placed
6615 wherever there is enough space for it, and IDATA can be anywhere
6616 in internal RAM. For now compile using -Wl-Y[stack_size].
6617 The mem file is different for this option as well, since it
6618 makes no sense of talking about DSEG lenght.

7606 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
7608 * device/lib/_mullong.c: replaced int by short for gcc
7610 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7612 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
7613 and JUMPTABLE iCodes properly now (worked by accident before)
7614 * src/mcs51/gen.c (leftRightUseAcc),
7615 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
7616 iCode properly now. Use getSize instead of nRegs since a & b
7617 aren't part of the nRegs tally.
7619 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
7621 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
7622 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
7623 before instructions that use the _STATUS register
7625 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
7627 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7628 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7629 fetching of the pointer
7630 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7631 copied from genNearPointerSet()
7632 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7633 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7634 If they pop r0/r1 they must be called in the opposite order than aopOp().
7635 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7636 (resp. --stack-auto), prepared for --xstack

7642 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7644 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
7645 these ports have their own __sdcc_external_start()
7647 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7649 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7650 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7651 type for bits was changed. It resulted in bit variables becoming
7652 global, which is not permitted in PIC 14 assembly output.
7654 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7656 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7658 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7660 Z80 and MCS51 linkers complaint if a public symbol is defined

7669 A few small changes that speed up the peephole optimizer.
7673 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7675 Try to make the peephole optimizer smarter by maintaining
7676 an association between the assembly source code and the
7677 iCodes that originated them. Put this information to use
7678 with a new peephole rule condition "notVolatile" so that
7679 the rules can be aggressive yet still safe.
7684 * src/mcs51/peeph.def
7686 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7690 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7691 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7692 if the left or right operand symbols have the accuse flag set.
7694 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7696 Changed the type of the result of the ! (NOT) operator to char;
7697 previously it returned the same type as the source. This allows
7698 us to eliminate all the genFloatNot functions (all of its target
7699 implementations were very buggy) since !float can use the same
7702 * src/SDCCicode.c (ast2iCode): ! returns char
7703 * src/mcs51/gen.c (genNot, genNotFloat),
7704 * src/ds390/gen.c (genNot, genNotFloat),
7705 * src/z80/gen.c (genNot, genNotFloat),
7706 * src/pic/gen.c (genNot, genNotFloat),
7707 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
7709 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7711 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7712 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7713 during interrupts. Ensure WSAVE is located at a shared bank address.
7714 2. Fixed page selection in some places
7715 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7716 the registers name strings.
7717 4. Fixed "signed / unsigned compare" compiler warnings.
7718 5. The PIC port manages its own allocation of the general purpose
7719 registers, but makes no attempt to reuse them. As a result when
7720 compiling it soon runs out of general purpose registers. Some
7721 additional code was added to the files pcode.c and device.c to walk
7722 through the function call tree and rename the registers so that they
7732 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7733 genPlus() & genMinus() when the result is the same as left or right
7735 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7739 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7741 Made bitfield a distinct type from bit so that bitfields
7742 convert as per ANSI C and bits retain their traditional
7743 boolean style behaviour. Implemented bitfield support in
7751 * src/ds390/gen.c: bit v bitfield split
7752 * src/z80/gen.c: New support for bitfields
7753 * support/regression/tests/bitfields.c: reenabled z80,
7756 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7758 Rules 246.x, 247.x relate to bitfields, the others speed up
7759 access to xdata mapped I/O devices.
7761 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7763 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7765 Cleaned up genPackBits and genUnpackBits and added two helper
7766 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7767 for literal assignments in genPackBits (thanks to Frieder for
7773 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7775 Fixed bug #748310 (pointer to function type mishandled when the
7776 function name is omitted). Also fixed a SIGSEGV when a function
7777 attribute (reentrant, etc) is used on a non-function or on a
7778 function but misplaced before the parameter list.
7780 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7782 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7783 * support/Util/SDCCerr.h,
7784 * support/Util/SDCCerr.c: Added func attr misuse error msg
7786 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
7788 Fixed bug #787649 by anonymous
7789 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

7805 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7807 Made the constant following the "interrupt" keyword optional. If
7808 omitted, the function will not automatically be given an entry
7809 in the interrupt vector table (similar to #pragma NOIV, but
7810 less syntacticly kludgy). The interrupt number is also now
7811 range checked. Also fixed a bug in the high order bit example
7818 * support/Util/SDCCerr.c
7819 * support/Util/SDCCerr.h
7822 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7825 * src/SDCCicode.c (operandOperation): rewritten some ops
7826 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7827 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7829 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7830 be re-activated by defining REDUCE_LITERALS)
7831 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7832 unsigned, but are signed by default
7833 * src/SDCCval.c (constVal): rearranged
7834 * src/SDCCval.c (valMod): preliminary fix
7835 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8287 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8288 the regression tests I'm not brave enough to enable 245.b, 245.c
8289 * doc/sdccman.lyx: added latex preamble for hyperref package.
8290 Using pdflatex this will give you a hyperlinked pdf file with
8291 bookmarks. (prepend '%' before /usepackage if this breaks something)

8327 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
8329 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8331 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8332 it can be defined with CFLAGS when running configure
8333 * src/SDCCmain.c: fixed compiling + linking with object files
8335 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
8337 * configure.in: configure for pic16 port,
8338 added --disable-pic16-port
8339 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8340 * src/SDCCmain.c: linkOptions is changed to set *,
8341 added if/endif conditional macros to remove options help
8342 messages from optionsTable when a port is not configured, added
8343 support for the PIc16 port in the ports table, when executing
8344 the compiler with no port specified on command line, a default
8345 port is selected with the new macro DEFAULT_PORT which is
8346 defined in port.h, in setDefaultOptions() linkOptions is removed
8347 from initialization assignment, since now it is a set,
8348 parseCmdLine uses setParseWithComma for linkOptions, in
8349 linkEdit() linkOptions are accessed with new function indexSet()
8350 which returns the i'th item of a set variable. See SDCCset.c, in
8351 linkEdit() when calling buildCmdLine(), added linkOptions as
8352 last argument. Now users can pass arguments to gplink via the
8353 -Wl option, main() uses pic16glue() to glue up pic16 programs
8354 * src/SDCCpeeph.c: various changes to support pic16

8363 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
8365 * src/pic16/glue.c: commented out some error producing lines
8366 * src/pic16/main.c: __config directives are commented out to stop
8367 gpasm complaining and test the linkage with gplink, _linkCmd and
8368 _asmCmd changed to be more gplink and gpasm friendly
8369 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8370 produced an error when parsed, peep rule 12 is added to utilize
8371 movff, but it is commented out since the pCode does not support
8372 yet a command with 2 address arguments
8374 2003-05-18 <johan AT balder>
8376 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8377 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8403 2003-05-11 Borut Razem <borut.razem AT siol.net>
8405 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8406 the path of bin directory, so that PATH is the only env. variable, which has to be set
8407 in case of standard installation.
8408 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9437 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9439 * in \sdcc\as\mcs51\ changed these files in order to create an
9440 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9441 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9442 following files to include the previous two files: aslink.dsp,
9443 Makefile.aslink, Makefile.bcc, and Makefile.in.
9445 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9446 .adb instead of .cdb
9448 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9450 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9451 value from option --iram-size.
9453 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9455 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9458 2002-09-18 <wiml AT hhhh.org>
9460 * SDCClrange.h: exposed setFromRange() and setToRange()
9461 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9462 packRegsForAccUse() (bug 542397)
9463 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9464 multiple times and emitting the fetch operations more than once
9465 added aopGetUsesAcc() function to allow binary operators to
9466 fetch their operands in the correct order; made genMinus() emit
9467 compact code for X = LITERAL - Y
9469 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9470 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9471 sprintf() in line 1267.
9473 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9474 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9477 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9478 Changes to aslink (All the changes are marked with 'JCF'):
9480 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9483 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9484 area BSEG. Also moves, if possible, the DATA area down into the internal
9485 ram so more space is available.
9487 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9490 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9491 not bytes. Function summary() which creates a memory usage summary
9492 file with extension .mem. Reports of overlaping stack and small stack
9493 size. If the space for the stack is less than 16 bytes aslink trows a
9496 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9497 the 8051. Option 'y' for memory summary output file.
9499 Changes to sdcc (All the changes are marked with 'JCF'):
9501 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9503 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9504 overlaying area for it (uses RegBankUsed[4]).
9506 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9507 bank zero as used by default. By default aslink locates the stack
9508 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9509 the creation of the .mem file. Delegates the allocation of data area
9510 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9511 the begining of the stack area to aslink.
9513 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9514 glue() in SDCCglue.c creates an area for it.
9516 2002-09-03 Borut Razem <borut.razem AT siol.net>
9517 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9518 sdcc/src/pic/glue.c:
9519 introduced atexit() handler for teporay files removal in case of
9520 errors, assertions, ...
9522 2002-08-29 Borut Razem <borut.razem AT siol.net>
9523 * sdcc/support/cpp2/auto-host_vc_in.h:
9524 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9525 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9526 Maybe there is a similar problem with BORLANDC? It should be checked!
9528 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9529 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9530 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9531 was not executed, and the compiler (cl) launched a warning:
9532 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9534 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9535 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9537 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9538 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9540 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9541 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9542 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9543 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9544 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9545 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9546 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9547 - added Release configuration in VS projects
9548 - review of compiler an linker options
9549 - VC .exe files are generated in bin_vc directory, not to interfere
9550 with binaries generated from other projects (cygwin, mingw, bcc ...)
9552 * sdcc/src/yacc.dsp: added
9554 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9555 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9556 and insert the version number definitions from .version
9558 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9560 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

9570 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9572 2002-08-10 Borut Razem <borut.razem AT siol.net>
9573 * src/SDCCmain.c (main):
9574 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9575 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9576 The consequence was that some temporary files were not removed.
9579 unification of code in functions tempfilename() and tempfile():
9580 function tempnam() is defined in Visual Studio 6.0 and .NET
9582 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9584 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9585 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

9590 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9591 changed project type to Generic Project so that can be correcly converted to VS.NET project
9593 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9595 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9597 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9599 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9600 added return 0 statements after assert() to make compiler happy
9602 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9603 added newline in the def file to keep MSC compiler satisfied
9605 * sdcc/src/z80/gen.c:
9606 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9607 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9608 - solved MSC error in function aopDump()
9610 * sdcc_vc.h: define PREFIX as "\\sdcc"
9612 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9613 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9664 Initialized the new field char *Processor field to NULL in all ports
9667 Compiler generated registers for interrupt context saving
9668 were not getting allocated.
9670 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9673 Fixed left shift. Will promote the left side of a left shift
9674 if a) left shifting more than size of operand or b) when assigned
9675 to something size > size of left side
9677 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9785 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9787 * sdcc/src/SDCCloop.c:
9788 Previous fix was not good. basic blocks that have "break" or "return" are
9789 not really partof a loop , but live ranges used in these blocks should
9790 be live thru the entire loop, so set partOfLoop but don't add them to
9793 2002-02-21 <johan AT FRIJA>
9795 * src/SDCCcse.c: fixed bug #514308
9797 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
