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

2303 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2304 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2305 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2306 always available in leading double underscore form. The C99 support is
2307 mostly missing, but it's a start.
2308 * support/regression/tests/bug-227710.c: fixed nonconforming use of

2387 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2389 * device/lib/printf_large.c: removed inline assembly for portability and
2390 readability. Use printf_fast if speed or size are more important.
2391 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2392 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2394 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2396 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2397 prevent compiler warning
2399 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2401 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2402 moved to level 0 and declared as static. Also they are explicit
2403 placed in access bank. This was necessery because some times they
2404 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2405 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2406 optimizations. Currently only compare to unsigned char is implemented,
2407 * src/pic16/gen.c: added fReturnIdx array,
2408 * (struct resolvedIfx) is moved to gen.h and made public,
2409 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2410 * (aopForSym): added an optimization to directly store in stack of
2411 the operand of a SEND iCode,
2412 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2413 but as registers instead (AOP_REG) using the fReturnIdx array,
2414 * (pic16_freeAsmop): remove the freed register from the
2415 _G.sregsAlloc field,
2416 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2417 a compare of 'WREG',
2418 * (pic16_popGetTempRegCond): changed function prototype, now
2419 function takes also a bitVector argument v which holds the current
2420 set of registers that are allocated for stack access by aopForSym,
2421 registers allocated in aopForSym for accessing stack symbols are not
2422 any more part of the functions usedRegs field,
2423 * (genCall): some times aopOp is called for a stack variable to be
2424 send, aopForSym might perform the push, if this is true make sure
2425 that genCall doesn't push the variable twice by testing _G.resDirect,
2426 * (genFunction): changed testing for unspecified interrupt number
2427 from 256 to INTNO_UNSPEC,
2428 * modified selection scheme of frame pointer generation. Previously
2429 if function did use local registers a frame pointer was generated,
2430 now a frame pointer is generated only if function has arguments
2431 (that need PLUSW2 register access), or has stack arguments, or the
2432 compiler is not instructed to omit the frame pointer,
2433 * (genEndFunction): before restoring local registers that were saved
2434 in the function preamble, also restore the registers that *might*
2435 have been allocated for stack access,
2436 * (genRet): removed some old comments,
2437 * (genCmp, the active (RN's) version): added a call to the
2438 pic16_genCmp_special function to perform the compare with a more
2439 robust and optimized way,
2440 * (genInline): a feature has been added in inline code generation,
2441 which allows a wildcard variable substitution when writing inline
2442 assembly. Code is incomplete and experimental therefore undocumented,
2443 * (genCast): changed order of aopOp for result and right to allow
2444 aopForSym to directly load the result if possible,
2445 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2446 perform an optimized compare on some selected special occasions,
2447 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2448 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2449 generate an IVT any more,
2450 * src/pic16/main.c (pic16_optionsTable): added command line option
2452 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2453 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2455 * src/pic16/NOTES: Raphael Neider added in list of active developers
2456 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2457 jumptable_end to prevent bug #,
2458 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2459 inCond and outCond fields,
2460 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2461 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2462 turn off register spilling,
2463 * (packRegsForOneUse): synced with other ports' versions although it
2464 is not used currently,
2465 * (pic16_packRegisters): added an optimization while reading
2466 structure bitfields, some registers may be saved (malloc code is
2467 decreased by 80 bytes)
2469 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2471 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2472 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2473 this can be optimized more?
2475 2005-03-10 Raphael Neider <rneider AT web.de>
2477 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2478 genNearPointerGet): (hopefully) fixed access to bitfields via
2479 pointers (p->bitN = x; and x = p->bitN; failed)

3111 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3113 Adding support for replacing ljmps with sjmps in jumptables
3114 generated for switch statements. For now you need to set the
3115 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3116 Now 4 algorithms for mcs51 jumptable generation are used:
3117 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3118 addresses loaded pc-relative for up to 112 cases and stack-pushing
3119 target addresses loaded with offset from dptr for up to 256 cases.

3149 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3151 * added libc directory. The current version of LibC contains string
3152 functions, ctype functions and macros and some functions of the
3153 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3154 be extensively tested in the future. Standard disclaimer here.
3155 Library is not automatically build yet. But one can build it by
3156 invoking 'make' inside the libc directory.
3157 * added ADC library under libio. Preliminary version yet.

3163 temporary registers, its a buggy feature and will be removed,
3164 * (pic16_popGet): set register instance field in AOP_CRY,
3165 * (pic16_outBitC): fixed for results in size greater than 1,
3166 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3167 * (pic16_storeForReturn): optimized return of 0,
3168 * (genCmp): experimental code for new genCmp which uses PIC18's
3169 special compare&skip instructions. Initial tests fail some times
3170 with variables grater than 1 byte in size, so new code is disabled,
3171 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3173 * (genCast): began a fix to optimize the casting of a bit to another
3174 bit, now assigning a bitfield to another bitfield will fail, sorry,
3175 * src/pic16/main.c: disabled the use of lr-support feature,
3176 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3179 bits with offset (case PO_GPR_BIT),
3180 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3182 * (isBankInstruction): modified to return 0 for no banking instruction,
3183 and 1 for banking instruction,
3184 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3185 caused stop processing pCodes after a inline assembly block,
3186 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3187 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3188 registers when it shouldn't,
3189 * src/pic16/ralloc.c (allocReg): add preliminary support for
3190 supporting a limited set of temporary registers,
3192 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3194 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3195 genDataPointerSet): ensure assignments always copy in MSB to LSB
3197 (loadRegFromAop): recognize CLRH optimization,
3198 (genFunction): optimize RECEIVE iCodes in reentrant functions
3200 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6118 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
6119 'char' to 'int' can be omitted, if both operands are 'unsigned char';
6120 see feature request #877103
6121 * src/SDCCval.c: updated call of decorateType()
6122 (valBitwise): fixed bug #882876
6123 (valMinus): added promotion
6124 (valLogicAndOr): result is unsigned
6125 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
6126 * src/SDCCsymt.c (computeType),
6127 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
6128 must not cause an unsigned operation
6129 * src/pic/glue (pic14emitRegularMap),
6130 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
6132 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

6136 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
6138 * support/valdiag/tests/overflow.c: added shift tests
6146 * src/pic/pcodepeep.c,
6147 * src/pic/pcoderegs.c,
6149 * src/pic/ralloc.h: applied patch from Slade Rich;
6150 added support for multiple code pages and multiple RAM banks on the
6151 PIC 14 port. The ASM files now no longer simply assume all the
6152 code / RAM are in the same page / bank. This means the linker can
6153 safely allocate code/RAM of separate ASM files to different pages/banks.
6154 * doc/sdccman.lyx: added Slade's tips
6155 * src/mcs51/peeph.def: fixed bug #880768

6164 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
6167 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
6168 strtof is not part of C89 and isn't included with Mac OS X.
6170 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6172 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

6197 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6199 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6200 loaded with the linker search paths (-L arguments) and the libraries
6201 to be linked with the current source (-l arguments). Changes
6202 currently will affect only the pic16 port.
6203 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6204 include path the port specific paths and port specific libraries,
6205 * gplink command now contains the $3 argument,
6206 * src/pic16/device.h,
6207 * src/pic16/device.c,: structure PIC_device is made public and
6208 renamed to PIC16_device, the same for variable Pics which is renamed

6221 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
6223 Documenting changes from previous commits.
6224 * configure.in (version 1.56),
6225 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6226 when generating output files to configure the pic16 library,
6227 but now I've commented it out, since gputils aren't installed in the
6228 SF compile farm, so library won't compile
6230 * device/lib/Makefile.in (version 1.56): initially I've added in
6231 target 'all' the prerequestive 'model-pic16' so it compiled the
6232 pic16 library, but now I've commented it out for the same reasons
6234 * added targets 'model-pic16' and 'objects-pic16' to compile the
6236 * added target 'port-specific-objects-pic16' to handle the
6237 generated libraries and copy them into the build/ directory
6238 * added target 'clean-intermediate-pic16' to clean intermediate
6239 files into pic16 directory
6240 * in target 'installdirs' added line to create directory pic16 in
6241 the installation path
6243 * device/include/Makefile.in (version 1.11): in target 'install'
6244 added lines to copy all header files to installation path,
6245 * in target 'installdirs' added line create directory for pic16
6246 headers in the installation path

6261 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6262 option so that it actually works. Made it specific to the z80, since
6263 the gbz80 doesn't have these kinds of I/O ports.
6265 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6267 * device/include/z180.h,

6289 Mainly changes to support compilation of the device libraries
6290 * src/pic16/device.c: stack is allocated via symbol and not
6291 via literal number. The symbol is placed in the corresponding
6292 position of the data ram
6293 * (pic16_dump_section): relocatable and absolute uninitialized
6294 data are now emitted in sorted order to reduce section naming,
6295 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6296 weren't marked as being in the access bank,
6298 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6300 Added portion of GNU PIC Library under the directory
6301 device/include/pic16 and device/lib/pic16. These files
6302 contain the declarations of SFRs for the PIC18Fxx2 devices.
6303 The directory is initialized via configure from toplevel.
6305 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6307 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6333 all over. Telling LaTeX to be less strict with word spacing
6334 to better keep the right margin. Changed some notes about
6335 maintainance of the ports in section 3.2.1 - is it OK like this?
6337 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6375 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6377 * src/pic16/peeph.def: all peepholes with movff are commented out,
6378 because there is a problem in the pcode peep optimizer,
6379 * src/pic16/ralloc.c: the register allocator can now reuse local

6531 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6533 PIC16 port related changes:
6534 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6535 added variable stackPos,
6537 * gen.c: genCall, assignResultValue: added support for
6538 pushing/retrieving function parameters to/from stack,
6539 genFunction,genEndFunction: setup stack frame for the
6541 genAddrOf: will be changed according to bug 863624
6543 * added files genutils.c and genutils.h which contain gen*
6544 debugged and optimised functions extracted from gen.c
6546 * glue.c: added variable 'externs' which holds extern symbols,
6547 pic16emitRegularMap: is modified to properly handle relocatable
6548 symbols under the new scheme,
6549 pic16createInterruptVect: is modified
6550 pic16printPublics: is modified to emit 'global' assembler directives,
6551 added pic16_printExterns to print extern symbols,
6552 pic16glue: initializes stack/frame pointer in the beginning of
6553 the assembly output. Temporary hack, will be corrected later,
6554 because gplink yet does not support stack and SDCC does not
6555 yet support a type of crt0.o object to create the final binary.
6557 * Removed many lines that contain 8051 legacy code.
6558 * The code is finally placed under a 'code' directive.
6559 * Added port specific options.
6561 * _process_pragma: simplified since now we do not need *special*
6562 include file to define SFR registers. But a separate header
6563 will be needed. This will be developed later.
6564 * _pic16_parseOptions: added, parses port specific options:
6565 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6566 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6567 --preplace-udata-with=
6569 * _pic16_setDefaultOptions: modified to initialize section names,
6570 but hack is temporarly out of order since it needs improvement.
6571 * _pic16_genAssemblerPreamble: configuration words are emitted by
6572 their address instead of their name. This part is incomplete and
6573 supports only the 18Fxx2 devices. Other devices will emit an error
6574 during assembly since they do not contain the same set of config
6576 * _pic16_genIVT: is modified,
6578 * pcode.c: added definitions for some hardware registers that are needed
6580 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6581 All PCI entries are updated. Now LFSR is supported.
6582 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6583 * added pic16_newpCodeOpLit2 to support instructions with
6584 two literal arguments
6585 * pic16_pCode2str: corrected code that emits assembler instructions
6586 with two literal operands and those that have an access bit modifier
6587 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6588 this fixes a bug which caused some labels to be lost, when an
6589 assembler directive was added, i.e. banksel,
6590 * pic16_FixRegisterBanking: improved logic that causes the insertion
6592 * InlineFunction: functions that are called once, are not any more
6593 inlined. This can be a port option in the future,
6595 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6597 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6598 hold the corresponding uninitialized symbols,
6599 * pic16_allocProcessorRegister: registers have explicit marked the
6601 * pic16_allocInternalRegister: registers are explicit marked as
6603 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6604 processing list, so bit registers were lost,
6607 * ralloc.h: added field 'accessBank' and original symbol operand
6608 in register definition,
6609 * removed the field isMapped from register definition,
6611 ** Several functions have been removed from various sources:

6623 * support/scripts/inc2h.pl: changed definition of BIT_AT
6624 to emit 'sbit at' instead of 'bit at'. This was a request.
6626 PIC16 port related preliminary changes:
6627 * gen.c: prefixed function popRegFromString with
6628 pic16_ and all references to it corrected
6629 * pcode.c: all pic16_pc_* hardware registers prefixed
6630 with underscore (_),
6631 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6632 * ralloc.c: newReg(): when register is REG_SFR then
6633 set address to rIdx,
6634 pic16_allocProcessorRegister(): marks register wasUsed=0
6635 pic16_writeUsedRegs(): added a call to assign processor
6636 registers via pic16_assignFixedRegisters
6638 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6640 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6641 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6642 variables in unused register banks. Also the SSEG is placed
6643 wherever there is enough space for it, and IDATA can be anywhere
6644 in internal RAM. For now compile using -Wl-Y[stack_size].
6645 The mem file is different for this option as well, since it
6646 makes no sense of talking about DSEG lenght.
6648 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6650 * src/SDCClrange.c: fixed bug 869095 that caused segfault

6895 * src/SDCCast.c (decorateType): disabled a transformation I added in
6896 revision 1.188 (access to fields of a structure at an absolute address);
6897 it breaks with bitfields, extern declarations, and gcse analysis.
6898 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6899 could be assigned through a pointer, so don't complain.

7643 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
7644 iCode properly now. Use getSize instead of nRegs since a & b
7645 aren't part of the nRegs tally.
7647 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
7649 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

7655 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7656 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7657 fetching of the pointer
7658 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7659 copied from genNearPointerSet()
7660 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7661 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7662 If they pop r0/r1 they must be called in the opposite order than aopOp().
7663 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7664 (resp. --stack-auto), prepared for --xstack

7675 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7677 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7678 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7679 type for bits was changed. It resulted in bit variables becoming
7680 global, which is not permitted in PIC 14 assembly output.
7682 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7684 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7686 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7688 Z80 and MCS51 linkers complaint if a public symbol is defined
7689 in more than one library module:

7695 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7697 A few small changes that speed up the peephole optimizer.
7701 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7703 Try to make the peephole optimizer smarter by maintaining
7704 an association between the assembly source code and the
7705 iCodes that originated them. Put this information to use
7706 with a new peephole rule condition "notVolatile" so that
7707 the rules can be aggressive yet still safe.
7712 * src/mcs51/peeph.def
7714 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7718 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7719 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7720 if the left or right operand symbols have the accuse flag set.
7722 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7724 Changed the type of the result of the ! (NOT) operator to char;
7725 previously it returned the same type as the source. This allows
7726 us to eliminate all the genFloatNot functions (all of its target
7727 implementations were very buggy) since !float can use the same
7730 * src/SDCCicode.c (ast2iCode): ! returns char
7731 * src/mcs51/gen.c (genNot, genNotFloat),
7732 * src/ds390/gen.c (genNot, genNotFloat),
7733 * src/z80/gen.c (genNot, genNotFloat),
7734 * src/pic/gen.c (genNot, genNotFloat),
7735 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
7737 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7739 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7740 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7741 during interrupts. Ensure WSAVE is located at a shared bank address.
7742 2. Fixed page selection in some places
7743 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7744 the registers name strings.
7745 4. Fixed "signed / unsigned compare" compiler warnings.
7746 5. The PIC port manages its own allocation of the general purpose
7747 registers, but makes no attempt to reuse them. As a result when
7748 compiling it soon runs out of general purpose registers. Some
7749 additional code was added to the files pcode.c and device.c to walk
7750 through the function call tree and rename the registers so that they
7760 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7761 genPlus() & genMinus() when the result is the same as left or right

7767 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7769 Made bitfield a distinct type from bit so that bitfields
7770 convert as per ANSI C and bits retain their traditional
7771 boolean style behaviour. Implemented bitfield support in
7779 * src/ds390/gen.c: bit v bitfield split
7780 * src/z80/gen.c: New support for bitfields
7781 * support/regression/tests/bitfields.c: reenabled z80,
7784 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7786 Rules 246.x, 247.x relate to bitfields, the others speed up
7787 access to xdata mapped I/O devices.
7789 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7791 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7793 Cleaned up genPackBits and genUnpackBits and added two helper
7794 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7795 for literal assignments in genPackBits (thanks to Frieder for
7801 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7803 Fixed bug #748310 (pointer to function type mishandled when the
7804 function name is omitted). Also fixed a SIGSEGV when a function
7805 attribute (reentrant, etc) is used on a non-function or on a
7806 function but misplaced before the parameter list.
7808 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7810 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

7833 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7835 Made the constant following the "interrupt" keyword optional. If
7836 omitted, the function will not automatically be given an entry
7837 in the interrupt vector table (similar to #pragma NOIV, but
7838 less syntacticly kludgy). The interrupt number is also now
7839 range checked. Also fixed a bug in the high order bit example
7846 * support/Util/SDCCerr.c
7847 * support/Util/SDCCerr.h
7850 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

7853 * src/SDCCicode.c (operandOperation): rewritten some ops
7854 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7855 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7857 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7858 be re-activated by defining REDUCE_LITERALS)
7859 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7860 unsigned, but are signed by default
7861 * src/SDCCval.c (constVal): rearranged
7862 * src/SDCCval.c (valMod): preliminary fix
7863 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8315 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8316 the regression tests I'm not brave enough to enable 245.b, 245.c
8317 * doc/sdccman.lyx: added latex preamble for hyperref package.
8318 Using pdflatex this will give you a hyperlinked pdf file with
8319 bookmarks. (prepend '%' before /usepackage if this breaks something)

8357 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
8359 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
8360 it can be defined with CFLAGS when running configure
8361 * src/SDCCmain.c: fixed compiling + linking with object files
8363 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

8366 added --disable-pic16-port
8367 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
8368 * src/SDCCmain.c: linkOptions is changed to set *,
8369 added if/endif conditional macros to remove options help
8370 messages from optionsTable when a port is not configured, added
8371 support for the PIc16 port in the ports table, when executing
8372 the compiler with no port specified on command line, a default
8373 port is selected with the new macro DEFAULT_PORT which is
8374 defined in port.h, in setDefaultOptions() linkOptions is removed
8375 from initialization assignment, since now it is a set,
8376 parseCmdLine uses setParseWithComma for linkOptions, in
8377 linkEdit() linkOptions are accessed with new function indexSet()
8378 which returns the i'th item of a set variable. See SDCCset.c, in
8379 linkEdit() when calling buildCmdLine(), added linkOptions as
8380 last argument. Now users can pass arguments to gplink via the
8381 -Wl option, main() uses pic16glue() to glue up pic16 programs

8393 * src/pic16/glue.c: commented out some error producing lines
8394 * src/pic16/main.c: __config directives are commented out to stop
8395 gpasm complaining and test the linkage with gplink, _linkCmd and
8396 _asmCmd changed to be more gplink and gpasm friendly
8397 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8398 produced an error when parsed, peep rule 12 is added to utilize
8399 movff, but it is commented out since the pCode does not support
8400 yet a command with 2 address arguments
8402 2003-05-18 <johan AT balder>
8404 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8431 2003-05-11 Borut Razem <borut.razem AT siol.net>
8433 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8434 the path of bin directory, so that PATH is the only env. variable, which has to be set
8435 in case of standard installation.
8436 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9529 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9531 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9532 overlaying area for it (uses RegBankUsed[4]).
9534 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9535 bank zero as used by default. By default aslink locates the stack
9536 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9537 the creation of the .mem file. Delegates the allocation of data area
9538 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9539 the begining of the stack area to aslink.
9541 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9542 glue() in SDCCglue.c creates an area for it.
9544 2002-09-03 Borut Razem <borut.razem AT siol.net>
9545 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9546 sdcc/src/pic/glue.c:
9547 introduced atexit() handler for teporay files removal in case of
9548 errors, assertions, ...
9550 2002-08-29 Borut Razem <borut.razem AT siol.net>
9551 * sdcc/support/cpp2/auto-host_vc_in.h:
9552 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9553 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9554 Maybe there is a similar problem with BORLANDC? It should be checked!
9556 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9557 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9558 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9559 was not executed, and the compiler (cl) launched a warning:
9560 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9562 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9563 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9565 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9566 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9568 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9569 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9570 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9571 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9572 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9573 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9574 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9575 - added Release configuration in VS projects
9576 - review of compiler an linker options
9577 - VC .exe files are generated in bin_vc directory, not to interfere
9578 with binaries generated from other projects (cygwin, mingw, bcc ...)
9580 * sdcc/src/yacc.dsp: added
9582 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9583 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9584 and insert the version number definitions from .version
9586 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9588 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9589 added - genarate auto-host.h using auto-host_vc_in.h as template
9592 removed from CVS, generated automatically
9594 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9595 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9597 2002-08-11 Borut Razem <borut.razem AT siol.net>
9598 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9600 2002-08-10 Borut Razem <borut.razem AT siol.net>
9601 * src/SDCCmain.c (main):
9602 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9603 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9604 The consequence was that some temporary files were not removed.
9607 unification of code in functions tempfilename() and tempfile():
9608 function tempnam() is defined in Visual Studio 6.0 and .NET
9610 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9612 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9613 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9614 - removed compiler command line option /WX: Treats all warnings as errors
9615 - update a list of source files, included into the project
9617 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9618 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9619 changed project type to Generic Project so that can be correcly converted to VS.NET project
9621 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9623 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9625 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9627 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9628 added return 0 statements after assert() to make compiler happy
9630 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9631 added newline in the def file to keep MSC compiler satisfied
9633 * sdcc/src/z80/gen.c:
9634 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9635 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9636 - solved MSC error in function aopDump()
9638 * sdcc_vc.h: define PREFIX as "\\sdcc"
9640 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9641 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9689 Added -p option. Allows port dependent processor to be specified.
9692 Initialized the new field char *Processor field to NULL in all ports
9695 Compiler generated registers for interrupt context saving
9696 were not getting allocated.
9698 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9701 Fixed left shift. Will promote the left side of a left shift
9702 if a) left shifting more than size of operand or b) when assigned
9703 to something size > size of left side
9705 2002-03-14 Scott Dattalo <scott AT dattalo.com>

9813 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9815 * sdcc/src/SDCCloop.c:
9816 Previous fix was not good. basic blocks that have "break" or "return" are
9817 not really partof a loop , but live ranges used in these blocks should
9818 be live thru the entire loop, so set partOfLoop but don't add them to
9821 2002-02-21 <johan AT FRIJA>
9823 * src/SDCCcse.c: fixed bug #514308
9825 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

9831 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9833 2002-02-10 Karl Bongers <karl AT turbobit.com>
