3 * src/pic16/gen.c (genPcall): fixed bug #1443644
4 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
5 which dumps before the function entry point a data byte which represents
6 the number of the local variables used by the specified function, added
7 'xinst' for initial support for Extended Instruction Support,
8 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
9 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
10 port->fun_prefix anymore (may change later),
11 (genFunction, genEndFunction): do not store/restore local registers for
12 _main (this should take care the --main-return command line option in
14 (genOr): removed some legacy pic-port instructions,
15 * src/pic16/genarith.c (genAddLit): re-enabled old code because
16 performing operations with SFR's causes data to be written more than
17 once to each SFR. Perhaps SFRs should be handled in special cases...
18 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
20 * src/pic16/main.c (_process_pragma): stack bound checking did not take
21 into account for stack starting position,
22 (struct OPTIONS pic16_optionsTable): added command line argument
23 --extended or -y for Extended Instruction Support,
24 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
25 (deassignLRs): *** perhaps the most important change, old 'for' code
26 (comented out for reference), didn't account for some registers which
27 were left marked 'not free' after a pointer operation. The change
28 reduces register usage a lot in some cases

2304 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2305 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2306 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2307 always available in leading double underscore form. The C99 support is
2308 mostly missing, but it's a start.
2309 * support/regression/tests/bug-227710.c: fixed nonconforming use of

2388 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2390 * device/lib/printf_large.c: removed inline assembly for portability and
2391 readability. Use printf_fast if speed or size are more important.
2392 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2393 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2395 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2397 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2398 prevent compiler warning
2400 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2402 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2403 moved to level 0 and declared as static. Also they are explicit
2404 placed in access bank. This was necessery because some times they
2405 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2406 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2407 optimizations. Currently only compare to unsigned char is implemented,
2408 * src/pic16/gen.c: added fReturnIdx array,
2409 * (struct resolvedIfx) is moved to gen.h and made public,
2410 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2411 * (aopForSym): added an optimization to directly store in stack of
2412 the operand of a SEND iCode,
2413 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2414 but as registers instead (AOP_REG) using the fReturnIdx array,
2415 * (pic16_freeAsmop): remove the freed register from the
2416 _G.sregsAlloc field,
2417 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2418 a compare of 'WREG',
2419 * (pic16_popGetTempRegCond): changed function prototype, now
2420 function takes also a bitVector argument v which holds the current
2421 set of registers that are allocated for stack access by aopForSym,
2422 registers allocated in aopForSym for accessing stack symbols are not
2423 any more part of the functions usedRegs field,
2424 * (genCall): some times aopOp is called for a stack variable to be
2425 send, aopForSym might perform the push, if this is true make sure
2426 that genCall doesn't push the variable twice by testing _G.resDirect,
2427 * (genFunction): changed testing for unspecified interrupt number
2428 from 256 to INTNO_UNSPEC,
2429 * modified selection scheme of frame pointer generation. Previously
2430 if function did use local registers a frame pointer was generated,
2431 now a frame pointer is generated only if function has arguments
2432 (that need PLUSW2 register access), or has stack arguments, or the
2433 compiler is not instructed to omit the frame pointer,
2434 * (genEndFunction): before restoring local registers that were saved
2435 in the function preamble, also restore the registers that *might*
2436 have been allocated for stack access,
2437 * (genRet): removed some old comments,
2438 * (genCmp, the active (RN's) version): added a call to the
2439 pic16_genCmp_special function to perform the compare with a more
2440 robust and optimized way,
2441 * (genInline): a feature has been added in inline code generation,
2442 which allows a wildcard variable substitution when writing inline
2443 assembly. Code is incomplete and experimental therefore undocumented,
2444 * (genCast): changed order of aopOp for result and right to allow
2445 aopForSym to directly load the result if possible,
2446 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2447 perform an optimized compare on some selected special occasions,
2448 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2449 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2450 generate an IVT any more,
2451 * src/pic16/main.c (pic16_optionsTable): added command line option
2453 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2454 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2456 * src/pic16/NOTES: Raphael Neider added in list of active developers
2457 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2458 jumptable_end to prevent bug #,
2459 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2460 inCond and outCond fields,
2461 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2462 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2463 turn off register spilling,
2464 * (packRegsForOneUse): synced with other ports' versions although it
2465 is not used currently,
2466 * (pic16_packRegisters): added an optimization while reading
2467 structure bitfields, some registers may be saved (malloc code is
2468 decreased by 80 bytes)
2470 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2472 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2473 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2474 this can be optimized more?
2476 2005-03-10 Raphael Neider <rneider AT web.de>
2478 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2479 genNearPointerGet): (hopefully) fixed access to bitfields via
2480 pointers (p->bitN = x; and x = p->bitN; failed)
2482 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3112 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3114 Adding support for replacing ljmps with sjmps in jumptables
3115 generated for switch statements. For now you need to set the
3116 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3117 Now 4 algorithms for mcs51 jumptable generation are used:
3118 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3119 addresses loaded pc-relative for up to 112 cases and stack-pushing
3120 target addresses loaded with offset from dptr for up to 256 cases.

3150 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3152 * added libc directory. The current version of LibC contains string
3153 functions, ctype functions and macros and some functions of the
3154 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3155 be extensively tested in the future. Standard disclaimer here.
3156 Library is not automatically build yet. But one can build it by
3157 invoking 'make' inside the libc directory.
3158 * added ADC library under libio. Preliminary version yet.
3160 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

3164 temporary registers, its a buggy feature and will be removed,
3165 * (pic16_popGet): set register instance field in AOP_CRY,
3166 * (pic16_outBitC): fixed for results in size greater than 1,
3167 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3168 * (pic16_storeForReturn): optimized return of 0,
3169 * (genCmp): experimental code for new genCmp which uses PIC18's
3170 special compare&skip instructions. Initial tests fail some times
3171 with variables grater than 1 byte in size, so new code is disabled,
3172 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3174 * (genCast): began a fix to optimize the casting of a bit to another
3175 bit, now assigning a bitfield to another bitfield will fail, sorry,
3176 * src/pic16/main.c: disabled the use of lr-support feature,
3177 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3180 bits with offset (case PO_GPR_BIT),
3181 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3183 * (isBankInstruction): modified to return 0 for no banking instruction,
3184 and 1 for banking instruction,
3185 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3186 caused stop processing pCodes after a inline assembly block,
3187 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3188 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3189 registers when it shouldn't,
3190 * src/pic16/ralloc.c (allocReg): add preliminary support for
3191 supporting a limited set of temporary registers,
3193 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3195 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3196 genDataPointerSet): ensure assignments always copy in MSB to LSB
3198 (loadRegFromAop): recognize CLRH optimization,
3199 (genFunction): optimize RECEIVE iCodes in reentrant functions
3201 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6118 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
6119 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
6120 'char' to 'int' can be omitted, if both operands are 'unsigned char';
6121 see feature request #877103
6122 * src/SDCCval.c: updated call of decorateType()
6123 (valBitwise): fixed bug #882876
6124 (valMinus): added promotion
6125 (valLogicAndOr): result is unsigned
6126 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
6127 * src/SDCCsymt.c (computeType),
6128 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
6129 must not cause an unsigned operation
6130 * src/pic/glue (pic14emitRegularMap),
6131 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
6133 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

6150 * src/pic/ralloc.h: applied patch from Slade Rich;
6151 added support for multiple code pages and multiple RAM banks on the
6152 PIC 14 port. The ASM files now no longer simply assume all the
6153 code / RAM are in the same page / bank. This means the linker can
6154 safely allocate code/RAM of separate ASM files to different pages/banks.
6155 * doc/sdccman.lyx: added Slade's tips
6156 * src/mcs51/peeph.def: fixed bug #880768

6198 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6200 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6201 loaded with the linker search paths (-L arguments) and the libraries
6202 to be linked with the current source (-l arguments). Changes
6203 currently will affect only the pic16 port.
6204 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6205 include path the port specific paths and port specific libraries,
6206 * gplink command now contains the $3 argument,
6207 * src/pic16/device.h,
6208 * src/pic16/device.c,: structure PIC_device is made public and
6209 renamed to PIC16_device, the same for variable Pics which is renamed

6222 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
6224 Documenting changes from previous commits.
6225 * configure.in (version 1.56),
6226 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6227 when generating output files to configure the pic16 library,
6228 but now I've commented it out, since gputils aren't installed in the
6229 SF compile farm, so library won't compile
6231 * device/lib/Makefile.in (version 1.56): initially I've added in
6232 target 'all' the prerequestive 'model-pic16' so it compiled the
6233 pic16 library, but now I've commented it out for the same reasons
6235 * added targets 'model-pic16' and 'objects-pic16' to compile the
6237 * added target 'port-specific-objects-pic16' to handle the
6238 generated libraries and copy them into the build/ directory
6239 * added target 'clean-intermediate-pic16' to clean intermediate
6240 files into pic16 directory
6241 * in target 'installdirs' added line to create directory pic16 in
6242 the installation path
6244 * device/include/Makefile.in (version 1.11): in target 'install'
6245 added lines to copy all header files to installation path,
6246 * in target 'installdirs' added line create directory for pic16
6247 headers in the installation path

6262 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6263 option so that it actually works. Made it specific to the z80, since
6264 the gbz80 doesn't have these kinds of I/O ports.
6266 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6268 * device/include/z180.h,

6290 Mainly changes to support compilation of the device libraries
6291 * src/pic16/device.c: stack is allocated via symbol and not
6292 via literal number. The symbol is placed in the corresponding
6293 position of the data ram
6294 * (pic16_dump_section): relocatable and absolute uninitialized
6295 data are now emitted in sorted order to reduce section naming,
6296 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6297 weren't marked as being in the access bank,
6299 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6301 Added portion of GNU PIC Library under the directory
6302 device/include/pic16 and device/lib/pic16. These files
6303 contain the declarations of SFRs for the PIC18Fxx2 devices.
6304 The directory is initialized via configure from toplevel.
6306 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6308 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6334 all over. Telling LaTeX to be less strict with word spacing
6335 to better keep the right margin. Changed some notes about
6336 maintainance of the ports in section 3.2.1 - is it OK like this?
6338 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6376 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6378 * src/pic16/peeph.def: all peepholes with movff are commented out,
6379 because there is a problem in the pcode peep optimizer,
6380 * src/pic16/ralloc.c: the register allocator can now reuse local

6519 Bug reported from Jesus Calvino-Fraga
6521 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6523 * sdcc.spec: updated
6524 * device/include/Makefile.in: don't install CVS directories

6532 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6534 PIC16 port related changes:
6535 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6536 added variable stackPos,
6538 * gen.c: genCall, assignResultValue: added support for
6539 pushing/retrieving function parameters to/from stack,
6540 genFunction,genEndFunction: setup stack frame for the
6542 genAddrOf: will be changed according to bug 863624
6544 * added files genutils.c and genutils.h which contain gen*
6545 debugged and optimised functions extracted from gen.c
6547 * glue.c: added variable 'externs' which holds extern symbols,
6548 pic16emitRegularMap: is modified to properly handle relocatable
6549 symbols under the new scheme,
6550 pic16createInterruptVect: is modified
6551 pic16printPublics: is modified to emit 'global' assembler directives,
6552 added pic16_printExterns to print extern symbols,
6553 pic16glue: initializes stack/frame pointer in the beginning of
6554 the assembly output. Temporary hack, will be corrected later,
6555 because gplink yet does not support stack and SDCC does not
6556 yet support a type of crt0.o object to create the final binary.
6558 * Removed many lines that contain 8051 legacy code.
6559 * The code is finally placed under a 'code' directive.
6560 * Added port specific options.
6562 * _process_pragma: simplified since now we do not need *special*
6563 include file to define SFR registers. But a separate header
6564 will be needed. This will be developed later.
6565 * _pic16_parseOptions: added, parses port specific options:
6566 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6567 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6568 --preplace-udata-with=
6570 * _pic16_setDefaultOptions: modified to initialize section names,
6571 but hack is temporarly out of order since it needs improvement.
6572 * _pic16_genAssemblerPreamble: configuration words are emitted by
6573 their address instead of their name. This part is incomplete and
6574 supports only the 18Fxx2 devices. Other devices will emit an error
6575 during assembly since they do not contain the same set of config
6577 * _pic16_genIVT: is modified,
6579 * pcode.c: added definitions for some hardware registers that are needed
6581 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6582 All PCI entries are updated. Now LFSR is supported.
6583 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6584 * added pic16_newpCodeOpLit2 to support instructions with
6585 two literal arguments
6586 * pic16_pCode2str: corrected code that emits assembler instructions
6587 with two literal operands and those that have an access bit modifier
6588 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6589 this fixes a bug which caused some labels to be lost, when an
6590 assembler directive was added, i.e. banksel,
6591 * pic16_FixRegisterBanking: improved logic that causes the insertion
6593 * InlineFunction: functions that are called once, are not any more
6594 inlined. This can be a port option in the future,
6596 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6598 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6599 hold the corresponding uninitialized symbols,
6600 * pic16_allocProcessorRegister: registers have explicit marked the
6602 * pic16_allocInternalRegister: registers are explicit marked as
6604 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6605 processing list, so bit registers were lost,
6608 * ralloc.h: added field 'accessBank' and original symbol operand
6609 in register definition,
6610 * removed the field isMapped from register definition,
6612 ** Several functions have been removed from various sources:
6613 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,

6622 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6624 * support/scripts/inc2h.pl: changed definition of BIT_AT
6625 to emit 'sbit at' instead of 'bit at'. This was a request.
6627 PIC16 port related preliminary changes:
6628 * gen.c: prefixed function popRegFromString with
6629 pic16_ and all references to it corrected
6630 * pcode.c: all pic16_pc_* hardware registers prefixed
6631 with underscore (_),
6632 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6633 * ralloc.c: newReg(): when register is REG_SFR then
6634 set address to rIdx,
6635 pic16_allocProcessorRegister(): marks register wasUsed=0
6636 pic16_writeUsedRegs(): added a call to assign processor
6637 registers via pic16_assignFixedRegisters
6639 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6641 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6642 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6643 variables in unused register banks. Also the SSEG is placed
6644 wherever there is enough space for it, and IDATA can be anywhere
6645 in internal RAM. For now compile using -Wl-Y[stack_size].
6646 The mem file is different for this option as well, since it
6647 makes no sense of talking about DSEG lenght.
6649 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6651 * src/SDCClrange.c: fixed bug 869095 that caused segfault

6898 it breaks with bitfields, extern declarations, and gcse analysis.
6899 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6900 could be assigned through a pointer, so don't complain.

7644 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
7645 iCode properly now. Use getSize instead of nRegs since a & b
7646 aren't part of the nRegs tally.
7648 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
7650 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

7656 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7657 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7658 fetching of the pointer
7659 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7660 copied from genNearPointerSet()
7661 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7662 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7663 If they pop r0/r1 they must be called in the opposite order than aopOp().
7664 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7665 (resp. --stack-auto), prepared for --xstack

7676 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7678 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7679 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7680 type for bits was changed. It resulted in bit variables becoming
7681 global, which is not permitted in PIC 14 assembly output.
7683 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7685 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7687 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7689 Z80 and MCS51 linkers complaint if a public symbol is defined
7690 in more than one library module:

7696 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7698 A few small changes that speed up the peephole optimizer.
7702 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7704 Try to make the peephole optimizer smarter by maintaining
7705 an association between the assembly source code and the
7706 iCodes that originated them. Put this information to use
7707 with a new peephole rule condition "notVolatile" so that
7708 the rules can be aggressive yet still safe.
7713 * src/mcs51/peeph.def
7715 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7719 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7720 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7721 if the left or right operand symbols have the accuse flag set.
7723 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7725 Changed the type of the result of the ! (NOT) operator to char;
7726 previously it returned the same type as the source. This allows
7727 us to eliminate all the genFloatNot functions (all of its target
7728 implementations were very buggy) since !float can use the same
7731 * src/SDCCicode.c (ast2iCode): ! returns char
7732 * src/mcs51/gen.c (genNot, genNotFloat),
7733 * src/ds390/gen.c (genNot, genNotFloat),
7734 * src/z80/gen.c (genNot, genNotFloat),
7735 * src/pic/gen.c (genNot, genNotFloat),
7736 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
7738 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7740 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7741 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7742 during interrupts. Ensure WSAVE is located at a shared bank address.
7743 2. Fixed page selection in some places
7744 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7745 the registers name strings.
7746 4. Fixed "signed / unsigned compare" compiler warnings.
7747 5. The PIC port manages its own allocation of the general purpose
7748 registers, but makes no attempt to reuse them. As a result when
7749 compiling it soon runs out of general purpose registers. Some
7750 additional code was added to the files pcode.c and device.c to walk
7751 through the function call tree and rename the registers so that they
7761 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7762 genPlus() & genMinus() when the result is the same as left or right

7768 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7770 Made bitfield a distinct type from bit so that bitfields
7771 convert as per ANSI C and bits retain their traditional
7772 boolean style behaviour. Implemented bitfield support in
7780 * src/ds390/gen.c: bit v bitfield split
7781 * src/z80/gen.c: New support for bitfields
7782 * support/regression/tests/bitfields.c: reenabled z80,
7785 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7787 Rules 246.x, 247.x relate to bitfields, the others speed up
7788 access to xdata mapped I/O devices.
7790 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7792 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7794 Cleaned up genPackBits and genUnpackBits and added two helper
7795 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7796 for literal assignments in genPackBits (thanks to Frieder for
7802 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7804 Fixed bug #748310 (pointer to function type mishandled when the
7805 function name is omitted). Also fixed a SIGSEGV when a function
7806 attribute (reentrant, etc) is used on a non-function or on a
7807 function but misplaced before the parameter list.
7809 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7811 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

7834 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7836 Made the constant following the "interrupt" keyword optional. If
7837 omitted, the function will not automatically be given an entry
7838 in the interrupt vector table (similar to #pragma NOIV, but
7839 less syntacticly kludgy). The interrupt number is also now
7840 range checked. Also fixed a bug in the high order bit example
7847 * support/Util/SDCCerr.c
7848 * support/Util/SDCCerr.h
7851 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7854 * src/SDCCicode.c (operandOperation): rewritten some ops
7855 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7856 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7858 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7859 be re-activated by defining REDUCE_LITERALS)
7860 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7861 unsigned, but are signed by default
7862 * src/SDCCval.c (constVal): rearranged
7863 * src/SDCCval.c (valMod): preliminary fix
7864 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8316 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8317 the regression tests I'm not brave enough to enable 245.b, 245.c
8318 * doc/sdccman.lyx: added latex preamble for hyperref package.
8319 Using pdflatex this will give you a hyperlinked pdf file with
8320 bookmarks. (prepend '%' before /usepackage if this breaks something)

8358 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8360 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8361 it can be defined with CFLAGS when running configure
8362 * src/SDCCmain.c: fixed compiling + linking with object files
8364 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

8367 added --disable-pic16-port
8368 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8369 * src/SDCCmain.c: linkOptions is changed to set *,
8370 added if/endif conditional macros to remove options help
8371 messages from optionsTable when a port is not configured, added
8372 support for the PIc16 port in the ports table, when executing
8373 the compiler with no port specified on command line, a default
8374 port is selected with the new macro DEFAULT_PORT which is
8375 defined in port.h, in setDefaultOptions() linkOptions is removed
8376 from initialization assignment, since now it is a set,
8377 parseCmdLine uses setParseWithComma for linkOptions, in
8378 linkEdit() linkOptions are accessed with new function indexSet()
8379 which returns the i'th item of a set variable. See SDCCset.c, in
8380 linkEdit() when calling buildCmdLine(), added linkOptions as
8381 last argument. Now users can pass arguments to gplink via the
8382 -Wl option, main() uses pic16glue() to glue up pic16 programs

8394 * src/pic16/glue.c: commented out some error producing lines
8395 * src/pic16/main.c: __config directives are commented out to stop
8396 gpasm complaining and test the linkage with gplink, _linkCmd and
8397 _asmCmd changed to be more gplink and gpasm friendly
8398 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8399 produced an error when parsed, peep rule 12 is added to utilize
8400 movff, but it is commented out since the pCode does not support
8401 yet a command with 2 address arguments
8403 2003-05-18 <johan AT balder>
8405 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8432 2003-05-11 Borut Razem <borut.razem AT siol.net>
8434 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8435 the path of bin directory, so that PATH is the only env. variable, which has to be set
8436 in case of standard installation.
8437 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9530 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9532 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9533 overlaying area for it (uses RegBankUsed[4]).
9535 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9536 bank zero as used by default. By default aslink locates the stack
9537 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9538 the creation of the .mem file. Delegates the allocation of data area
9539 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9540 the begining of the stack area to aslink.
9542 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9543 glue() in SDCCglue.c creates an area for it.
9545 2002-09-03 Borut Razem <borut.razem AT siol.net>
9546 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9547 sdcc/src/pic/glue.c:
9548 introduced atexit() handler for teporay files removal in case of
9549 errors, assertions, ...
9551 2002-08-29 Borut Razem <borut.razem AT siol.net>
9552 * sdcc/support/cpp2/auto-host_vc_in.h:
9553 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9554 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9555 Maybe there is a similar problem with BORLANDC? It should be checked!
9557 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9558 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9559 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9560 was not executed, and the compiler (cl) launched a warning:
9561 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9563 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9564 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9566 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9567 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9569 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9570 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9571 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9572 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9573 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9574 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9575 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9576 - added Release configuration in VS projects
9577 - review of compiler an linker options
9578 - VC .exe files are generated in bin_vc directory, not to interfere
9579 with binaries generated from other projects (cygwin, mingw, bcc ...)
9581 * sdcc/src/yacc.dsp: added
9583 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9584 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9585 and insert the version number definitions from .version
9587 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9589 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9590 added - genarate auto-host.h using auto-host_vc_in.h as template
9593 removed from CVS, generated automatically
9595 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9596 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9598 2002-08-11 Borut Razem <borut.razem AT siol.net>
9599 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9601 2002-08-10 Borut Razem <borut.razem AT siol.net>
9602 * src/SDCCmain.c (main):
9603 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9604 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9605 The consequence was that some temporary files were not removed.
9608 unification of code in functions tempfilename() and tempfile():
9609 function tempnam() is defined in Visual Studio 6.0 and .NET
9611 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9613 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9614 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9615 - removed compiler command line option /WX: Treats all warnings as errors
9616 - update a list of source files, included into the project
9618 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9619 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9620 changed project type to Generic Project so that can be correcly converted to VS.NET project
9622 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9624 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9626 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9628 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9629 added return 0 statements after assert() to make compiler happy
9631 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9632 added newline in the def file to keep MSC compiler satisfied
9634 * sdcc/src/z80/gen.c:
9635 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9636 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9637 - solved MSC error in function aopDump()
9639 * sdcc_vc.h: define PREFIX as "\\sdcc"
9641 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9642 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9690 Added -p option. Allows port dependent processor to be specified.
9693 Initialized the new field char *Processor field to NULL in all ports
9696 Compiler generated registers for interrupt context saving
9697 were not getting allocated.
9699 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9702 Fixed left shift. Will promote the left side of a left shift
9703 if a) left shifting more than size of operand or b) when assigned
9704 to something size > size of left side
9706 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9816 * sdcc/src/SDCCloop.c:
9817 Previous fix was not good. basic blocks that have "break" or "return" are
9818 not really partof a loop , but live ranges used in these blocks should
9819 be live thru the entire loop, so set partOfLoop but don't add them to
9822 2002-02-21 <johan AT FRIJA>
9824 * src/SDCCcse.c: fixed bug #514308
9826 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

9832 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9834 2002-02-10 Karl Bongers <karl AT turbobit.com>
