3 * src/pic16/main.c (_hasNativeMulFor): fixed bug #1444425
5 2006-03-07 Maarten Brock <sourceforge.brock AT dse.nl>
7 * device/include/mcs51/c8051f410.h: new SiLabs mcu
8 * src/ds390/peeph.def: disabled 186.d and 227.a as fix for #1434401
9 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
11 2006-03-06 Borut Razem <borut.razem AT siol.net>
13 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
16 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
18 * src/pic16/gen.c (genPcall): fixed bug #1443644
19 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
20 which dumps before the function entry point a data byte which represents
21 the number of the local variables used by the specified function, added
22 'xinst' for initial support for Extended Instruction Support,
23 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
24 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
25 port->fun_prefix anymore (may change later),
26 (genFunction, genEndFunction): do not store/restore local registers for
27 _main (this should take care the --main-return command line option in
29 (genOr): removed some legacy pic-port instructions,
30 * src/pic16/genarith.c (genAddLit): re-enabled old code because
31 performing operations with SFR's causes data to be written more than
32 once to each SFR. Perhaps SFRs should be handled in special cases...
33 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
35 * src/pic16/main.c (_process_pragma): stack bound checking did not take
36 into account for stack starting position,
37 (struct OPTIONS pic16_optionsTable): added command line argument
38 --extended or -y for Extended Instruction Support,
39 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
40 (deassignLRs): *** perhaps the most important change, old 'for' code
41 (commented out for reference), didn't account for some registers which
42 were left marked 'not free' after a pointer operation. The change
43 reduces register usage a lot in some cases

2318 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2319 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2320 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2321 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2322 always available in leading double underscore form. The C99 support is
2323 mostly missing, but it's a start.
2324 * support/regression/tests/bug-227710.c: fixed nonconforming use of

2403 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2405 * device/lib/printf_large.c: removed inline assembly for portability and
2406 readability. Use printf_fast if speed or size are more important.
2407 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2408 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2410 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2412 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2413 prevent compiler warning
2415 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2417 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2418 moved to level 0 and declared as static. Also they are explicit
2419 placed in access bank. This was necessery because some times they
2420 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2421 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2422 optimizations. Currently only compare to unsigned char is implemented,
2423 * src/pic16/gen.c: added fReturnIdx array,
2424 * (struct resolvedIfx) is moved to gen.h and made public,
2425 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2426 * (aopForSym): added an optimization to directly store in stack of
2427 the operand of a SEND iCode,
2428 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2429 but as registers instead (AOP_REG) using the fReturnIdx array,
2430 * (pic16_freeAsmop): remove the freed register from the
2431 _G.sregsAlloc field,
2432 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2433 a compare of 'WREG',
2434 * (pic16_popGetTempRegCond): changed function prototype, now
2435 function takes also a bitVector argument v which holds the current
2436 set of registers that are allocated for stack access by aopForSym,
2437 registers allocated in aopForSym for accessing stack symbols are not
2438 any more part of the functions usedRegs field,
2439 * (genCall): some times aopOp is called for a stack variable to be
2440 send, aopForSym might perform the push, if this is true make sure
2441 that genCall doesn't push the variable twice by testing _G.resDirect,
2442 * (genFunction): changed testing for unspecified interrupt number
2443 from 256 to INTNO_UNSPEC,
2444 * modified selection scheme of frame pointer generation. Previously
2445 if function did use local registers a frame pointer was generated,
2446 now a frame pointer is generated only if function has arguments
2447 (that need PLUSW2 register access), or has stack arguments, or the
2448 compiler is not instructed to omit the frame pointer,
2449 * (genEndFunction): before restoring local registers that were saved
2450 in the function preamble, also restore the registers that *might*
2451 have been allocated for stack access,
2452 * (genRet): removed some old comments,
2453 * (genCmp, the active (RN's) version): added a call to the
2454 pic16_genCmp_special function to perform the compare with a more
2455 robust and optimized way,
2456 * (genInline): a feature has been added in inline code generation,
2457 which allows a wildcard variable substitution when writing inline
2458 assembly. Code is incomplete and experimental therefore undocumented,
2459 * (genCast): changed order of aopOp for result and right to allow
2460 aopForSym to directly load the result if possible,
2461 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2462 perform an optimized compare on some selected special occasions,
2463 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2464 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2465 generate an IVT any more,
2466 * src/pic16/main.c (pic16_optionsTable): added command line option
2468 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2469 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2471 * src/pic16/NOTES: Raphael Neider added in list of active developers
2472 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2473 jumptable_end to prevent bug #,
2474 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2475 inCond and outCond fields,
2476 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2477 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2478 turn off register spilling,
2479 * (packRegsForOneUse): synced with other ports' versions although it
2480 is not used currently,
2481 * (pic16_packRegisters): added an optimization while reading
2482 structure bitfields, some registers may be saved (malloc code is
2483 decreased by 80 bytes)
2485 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2487 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2488 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2489 this can be optimized more?
2491 2005-03-10 Raphael Neider <rneider AT web.de>
2493 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2494 genNearPointerGet): (hopefully) fixed access to bitfields via
2495 pointers (p->bitN = x; and x = p->bitN; failed)
2497 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3129 Adding support for replacing ljmps with sjmps in jumptables
3130 generated for switch statements. For now you need to set the
3131 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3132 Now 4 algorithms for mcs51 jumptable generation are used:
3133 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3134 addresses loaded pc-relative for up to 112 cases and stack-pushing
3135 target addresses loaded with offset from dptr for up to 256 cases.

3165 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3167 * added libc directory. The current version of LibC contains string
3168 functions, ctype functions and macros and some functions of the
3169 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3170 be extensively tested in the future. Standard disclaimer here.
3171 Library is not automatically build yet. But one can build it by
3172 invoking 'make' inside the libc directory.
3173 * added ADC library under libio. Preliminary version yet.

3183 * (pic16_storeForReturn): optimized return of 0,
3184 * (genCmp): experimental code for new genCmp which uses PIC18's
3185 special compare&skip instructions. Initial tests fail some times
3186 with variables grater than 1 byte in size, so new code is disabled,
3187 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3189 * (genCast): began a fix to optimize the casting of a bit to another
3190 bit, now assigning a bitfield to another bitfield will fail, sorry,
3191 * src/pic16/main.c: disabled the use of lr-support feature,
3192 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3199 and 1 for banking instruction,
3200 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3201 caused stop processing pCodes after a inline assembly block,
3202 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3204 registers when it shouldn't,
3205 * src/pic16/ralloc.c (allocReg): add preliminary support for
3206 supporting a limited set of temporary registers,
3208 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6116 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
6119 * support/regression/generate-cases.py (main): Changed from inline
6122 * doc/Makefile (install): Changed to depth first to get rid of
6123 missing directory install warning.
6125 * as/Makefile (install-doc): Made work on Mac.
6127 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
6129 * src/SDCCast.c: added an additional type flow in decorateType() of
6130 opposite direction, see feature request #860006; it's enabled at runtime
6131 by setting the environment variable SDCC_NEWTYPEFLOW
6132 * src/SDCCast.h: changed prototype of decorateType()
6133 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
6134 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
6135 'char' to 'int' can be omitted, if both operands are 'unsigned char';
6136 see feature request #877103
6137 * src/SDCCval.c: updated call of decorateType()
6138 (valBitwise): fixed bug #882876
6139 (valMinus): added promotion
6140 (valLogicAndOr): result is unsigned
6141 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
6142 * src/SDCCsymt.c (computeType),
6143 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
6144 must not cause an unsigned operation
6145 * src/pic/glue (pic14emitRegularMap),
6146 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
6148 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>

6165 * src/pic/ralloc.h: applied patch from Slade Rich;
6166 added support for multiple code pages and multiple RAM banks on the
6167 PIC 14 port. The ASM files now no longer simply assume all the
6168 code / RAM are in the same page / bank. This means the linker can
6169 safely allocate code/RAM of separate ASM files to different pages/banks.
6170 * doc/sdccman.lyx: added Slade's tips
6171 * src/mcs51/peeph.def: fixed bug #880768

6183 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
6184 strtof is not part of C89 and isn't included with Mac OS X.
6186 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6188 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

6213 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6215 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6216 loaded with the linker search paths (-L arguments) and the libraries
6217 to be linked with the current source (-l arguments). Changes
6218 currently will affect only the pic16 port.
6219 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6220 include path the port specific paths and port specific libraries,
6221 * gplink command now contains the $3 argument,
6222 * src/pic16/device.h,
6223 * src/pic16/device.c,: structure PIC_device is made public and
6224 renamed to PIC16_device, the same for variable Pics which is renamed

6239 Documenting changes from previous commits.
6240 * configure.in (version 1.56),
6241 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6242 when generating output files to configure the pic16 library,
6243 but now I've commented it out, since gputils aren't installed in the
6244 SF compile farm, so library won't compile
6246 * device/lib/Makefile.in (version 1.56): initially I've added in
6247 target 'all' the prerequestive 'model-pic16' so it compiled the
6248 pic16 library, but now I've commented it out for the same reasons
6250 * added targets 'model-pic16' and 'objects-pic16' to compile the
6252 * added target 'port-specific-objects-pic16' to handle the
6253 generated libraries and copy them into the build/ directory
6254 * added target 'clean-intermediate-pic16' to clean intermediate
6255 files into pic16 directory
6256 * in target 'installdirs' added line to create directory pic16 in
6257 the installation path
6259 * device/include/Makefile.in (version 1.11): in target 'install'
6260 added lines to copy all header files to installation path,
6261 * in target 'installdirs' added line create directory for pic16
6262 headers in the installation path

6277 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6278 option so that it actually works. Made it specific to the z80, since
6279 the gbz80 doesn't have these kinds of I/O ports.
6281 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6283 * device/include/z180.h,

6305 Mainly changes to support compilation of the device libraries
6306 * src/pic16/device.c: stack is allocated via symbol and not
6307 via literal number. The symbol is placed in the corresponding
6308 position of the data ram
6309 * (pic16_dump_section): relocatable and absolute uninitialized
6310 data are now emitted in sorted order to reduce section naming,
6311 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6312 weren't marked as being in the access bank,
6314 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6316 Added portion of GNU PIC Library under the directory
6317 device/include/pic16 and device/lib/pic16. These files
6318 contain the declarations of SFRs for the PIC18Fxx2 devices.
6319 The directory is initialized via configure from toplevel.
6321 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
6323 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

6349 all over. Telling LaTeX to be less strict with word spacing
6350 to better keep the right margin. Changed some notes about
6351 maintainance of the ports in section 3.2.1 - is it OK like this?
6353 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

6393 * src/pic16/peeph.def: all peepholes with movff are commented out,
6394 because there is a problem in the pcode peep optimizer,
6395 * src/pic16/ralloc.c: the register allocator can now reuse local

6547 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6549 PIC16 port related changes:
6550 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6551 added variable stackPos,
6553 * gen.c: genCall, assignResultValue: added support for
6554 pushing/retrieving function parameters to/from stack,
6555 genFunction,genEndFunction: setup stack frame for the
6557 genAddrOf: will be changed according to bug 863624
6559 * added files genutils.c and genutils.h which contain gen*
6560 debugged and optimised functions extracted from gen.c
6562 * glue.c: added variable 'externs' which holds extern symbols,
6563 pic16emitRegularMap: is modified to properly handle relocatable
6564 symbols under the new scheme,
6565 pic16createInterruptVect: is modified
6566 pic16printPublics: is modified to emit 'global' assembler directives,
6567 added pic16_printExterns to print extern symbols,
6568 pic16glue: initializes stack/frame pointer in the beginning of
6569 the assembly output. Temporary hack, will be corrected later,
6570 because gplink yet does not support stack and SDCC does not
6571 yet support a type of crt0.o object to create the final binary.
6573 * Removed many lines that contain 8051 legacy code.
6574 * The code is finally placed under a 'code' directive.
6575 * Added port specific options.
6577 * _process_pragma: simplified since now we do not need *special*
6578 include file to define SFR registers. But a separate header
6579 will be needed. This will be developed later.
6580 * _pic16_parseOptions: added, parses port specific options:
6581 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6582 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6583 --preplace-udata-with=
6585 * _pic16_setDefaultOptions: modified to initialize section names,
6586 but hack is temporarly out of order since it needs improvement.
6587 * _pic16_genAssemblerPreamble: configuration words are emitted by
6588 their address instead of their name. This part is incomplete and
6589 supports only the 18Fxx2 devices. Other devices will emit an error
6590 during assembly since they do not contain the same set of config
6592 * _pic16_genIVT: is modified,
6594 * pcode.c: added definitions for some hardware registers that are needed
6596 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6597 All PCI entries are updated. Now LFSR is supported.
6598 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6599 * added pic16_newpCodeOpLit2 to support instructions with
6600 two literal arguments
6601 * pic16_pCode2str: corrected code that emits assembler instructions
6602 with two literal operands and those that have an access bit modifier
6603 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6604 this fixes a bug which caused some labels to be lost, when an
6605 assembler directive was added, i.e. banksel,
6606 * pic16_FixRegisterBanking: improved logic that causes the insertion
6608 * InlineFunction: functions that are called once, are not any more
6609 inlined. This can be a port option in the future,
6611 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6613 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6614 hold the corresponding uninitialized symbols,
6615 * pic16_allocProcessorRegister: registers have explicit marked the
6617 * pic16_allocInternalRegister: registers are explicit marked as
6619 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6620 processing list, so bit registers were lost,
6623 * ralloc.h: added field 'accessBank' and original symbol operand
6624 in register definition,
6625 * removed the field isMapped from register definition,
6627 ** Several functions have been removed from various sources:
6628 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6629 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6630 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6631 pic16_assignRelocatableRegisters
6633 ** others have been introduced:
6634 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6635 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6637 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6639 * support/scripts/inc2h.pl: changed definition of BIT_AT
6640 to emit 'sbit at' instead of 'bit at'. This was a request.
6642 PIC16 port related preliminary changes:
6643 * gen.c: prefixed function popRegFromString with
6644 pic16_ and all references to it corrected
6645 * pcode.c: all pic16_pc_* hardware registers prefixed
6646 with underscore (_),
6647 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6648 * ralloc.c: newReg(): when register is REG_SFR then
6649 set address to rIdx,
6650 pic16_allocProcessorRegister(): marks register wasUsed=0
6651 pic16_writeUsedRegs(): added a call to assign processor
6652 registers via pic16_assignFixedRegisters
6654 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6656 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6657 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6658 variables in unused register banks. Also the SSEG is placed
6659 wherever there is enough space for it, and IDATA can be anywhere
6660 in internal RAM. For now compile using -Wl-Y[stack_size].
6661 The mem file is different for this option as well, since it
6662 makes no sense of talking about DSEG lenght.
6664 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6666 * src/SDCClrange.c: fixed bug 869095 that caused segfault

6911 * src/SDCCast.c (decorateType): disabled a transformation I added in
6912 revision 1.188 (access to fields of a structure at an absolute address);
6913 it breaks with bitfields, extern declarations, and gcse analysis.
6914 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6915 could be assigned through a pointer, so don't complain.

7023 xdata initialization slightly shorter
7025 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7659 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
7660 iCode properly now. Use getSize instead of nRegs since a & b
7661 aren't part of the nRegs tally.
7663 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
7665 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

7672 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7673 fetching of the pointer
7674 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7675 copied from genNearPointerSet()
7676 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7677 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7678 If they pop r0/r1 they must be called in the opposite order than aopOp().
7679 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7680 (resp. --stack-auto), prepared for --xstack

7691 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7693 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7694 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7695 type for bits was changed. It resulted in bit variables becoming
7696 global, which is not permitted in PIC 14 assembly output.
7698 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7700 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7702 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7704 Z80 and MCS51 linkers complaint if a public symbol is defined
7705 in more than one library module:

7711 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7713 A few small changes that speed up the peephole optimizer.
7717 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7719 Try to make the peephole optimizer smarter by maintaining
7720 an association between the assembly source code and the
7721 iCodes that originated them. Put this information to use
7722 with a new peephole rule condition "notVolatile" so that
7723 the rules can be aggressive yet still safe.
7728 * src/mcs51/peeph.def
7730 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7734 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7735 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7736 if the left or right operand symbols have the accuse flag set.
7738 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7740 Changed the type of the result of the ! (NOT) operator to char;
7741 previously it returned the same type as the source. This allows
7742 us to eliminate all the genFloatNot functions (all of its target
7743 implementations were very buggy) since !float can use the same
7746 * src/SDCCicode.c (ast2iCode): ! returns char
7747 * src/mcs51/gen.c (genNot, genNotFloat),
7748 * src/ds390/gen.c (genNot, genNotFloat),
7749 * src/z80/gen.c (genNot, genNotFloat),
7750 * src/pic/gen.c (genNot, genNotFloat),
7751 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
7753 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7755 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7756 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7757 during interrupts. Ensure WSAVE is located at a shared bank address.
7758 2. Fixed page selection in some places
7759 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7760 the registers name strings.
7761 4. Fixed "signed / unsigned compare" compiler warnings.
7762 5. The PIC port manages its own allocation of the general purpose
7763 registers, but makes no attempt to reuse them. As a result when
7764 compiling it soon runs out of general purpose registers. Some
7765 additional code was added to the files pcode.c and device.c to walk
7766 through the function call tree and rename the registers so that they
7776 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7777 genPlus() & genMinus() when the result is the same as left or right

7783 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7785 Made bitfield a distinct type from bit so that bitfields
7786 convert as per ANSI C and bits retain their traditional
7787 boolean style behaviour. Implemented bitfield support in
7795 * src/ds390/gen.c: bit v bitfield split
7796 * src/z80/gen.c: New support for bitfields
7797 * support/regression/tests/bitfields.c: reenabled z80,
7800 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7802 Rules 246.x, 247.x relate to bitfields, the others speed up
7803 access to xdata mapped I/O devices.
7805 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7807 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7809 Cleaned up genPackBits and genUnpackBits and added two helper
7810 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7811 for literal assignments in genPackBits (thanks to Frieder for
7817 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7819 Fixed bug #748310 (pointer to function type mishandled when the
7820 function name is omitted). Also fixed a SIGSEGV when a function
7821 attribute (reentrant, etc) is used on a non-function or on a
7822 function but misplaced before the parameter list.
7824 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7826 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7827 * support/Util/SDCCerr.h,
7828 * support/Util/SDCCerr.c: Added func attr misuse error msg

7849 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7851 Made the constant following the "interrupt" keyword optional. If
7852 omitted, the function will not automatically be given an entry
7853 in the interrupt vector table (similar to #pragma NOIV, but
7854 less syntacticly kludgy). The interrupt number is also now
7855 range checked. Also fixed a bug in the high order bit example
7862 * support/Util/SDCCerr.c
7863 * support/Util/SDCCerr.h
7866 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
7868 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
7869 * src/SDCCicode.c (operandOperation): rewritten some ops
7870 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7871 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7873 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7874 be re-activated by defining REDUCE_LITERALS)
7875 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7876 unsigned, but are signed by default
7877 * src/SDCCval.c (constVal): rearranged
7878 * src/SDCCval.c (valMod): preliminary fix
7879 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7922 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7923 * src/SDCCval.c (valDiv, valMod): fixed signdness
7924 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7925 signedness of modulo, left and right shift

8331 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
8332 the regression tests I'm not brave enough to enable 245.b, 245.c
8333 * doc/sdccman.lyx: added latex preamble for hyperref package.
8334 Using pdflatex this will give you a hyperlinked pdf file with
8335 bookmarks. (prepend '%' before /usepackage if this breaks something)

8384 * src/SDCCmain.c: linkOptions is changed to set *,
8385 added if/endif conditional macros to remove options help
8386 messages from optionsTable when a port is not configured, added
8387 support for the PIc16 port in the ports table, when executing
8388 the compiler with no port specified on command line, a default
8389 port is selected with the new macro DEFAULT_PORT which is
8390 defined in port.h, in setDefaultOptions() linkOptions is removed
8391 from initialization assignment, since now it is a set,
8392 parseCmdLine uses setParseWithComma for linkOptions, in
8393 linkEdit() linkOptions are accessed with new function indexSet()
8394 which returns the i'th item of a set variable. See SDCCset.c, in
8395 linkEdit() when calling buildCmdLine(), added linkOptions as
8396 last argument. Now users can pass arguments to gplink via the
8397 -Wl option, main() uses pic16glue() to glue up pic16 programs

8409 * src/pic16/glue.c: commented out some error producing lines
8410 * src/pic16/main.c: __config directives are commented out to stop
8411 gpasm complaining and test the linkage with gplink, _linkCmd and
8412 _asmCmd changed to be more gplink and gpasm friendly
8413 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8414 produced an error when parsed, peep rule 12 is added to utilize
8415 movff, but it is commented out since the pCode does not support
8416 yet a command with 2 address arguments
8418 2003-05-18 <johan AT balder>
8420 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8447 2003-05-11 Borut Razem <borut.razem AT siol.net>
8449 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8450 the path of bin directory, so that PATH is the only env. variable, which has to be set
8451 in case of standard installation.
8452 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9534 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9535 not bytes. Function summary() which creates a memory usage summary
9536 file with extension .mem. Reports of overlaping stack and small stack
9537 size. If the space for the stack is less than 16 bytes aslink trows a
9540 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9541 the 8051. Option 'y' for memory summary output file.
9543 Changes to sdcc (All the changes are marked with 'JCF'):
9545 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9547 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9548 overlaying area for it (uses RegBankUsed[4]).
9550 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9551 bank zero as used by default. By default aslink locates the stack
9552 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9553 the creation of the .mem file. Delegates the allocation of data area
9554 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9555 the begining of the stack area to aslink.
9557 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9558 glue() in SDCCglue.c creates an area for it.
9560 2002-09-03 Borut Razem <borut.razem AT siol.net>
9561 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9562 sdcc/src/pic/glue.c:
9563 introduced atexit() handler for teporay files removal in case of
9564 errors, assertions, ...
9566 2002-08-29 Borut Razem <borut.razem AT siol.net>
9567 * sdcc/support/cpp2/auto-host_vc_in.h:
9568 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9569 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9570 Maybe there is a similar problem with BORLANDC? It should be checked!
9572 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9573 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9574 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9575 was not executed, and the compiler (cl) launched a warning:
9576 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9578 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9579 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9581 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9582 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
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,
9586 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9587 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9588 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9589 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9590 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9591 - added Release configuration in VS projects
9592 - review of compiler an linker options
9593 - VC .exe files are generated in bin_vc directory, not to interfere
9594 with binaries generated from other projects (cygwin, mingw, bcc ...)
9596 * sdcc/src/yacc.dsp: added
9598 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9599 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9600 and insert the version number definitions from .version
9602 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9604 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9605 added - genarate auto-host.h using auto-host_vc_in.h as template
9608 removed from CVS, generated automatically
9610 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9611 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9613 2002-08-11 Borut Razem <borut.razem AT siol.net>
9614 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9616 2002-08-10 Borut Razem <borut.razem AT siol.net>
9617 * src/SDCCmain.c (main):
9618 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9619 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9620 The consequence was that some temporary files were not removed.
9623 unification of code in functions tempfilename() and tempfile():
9624 function tempnam() is defined in Visual Studio 6.0 and .NET
9626 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9628 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9629 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9630 - removed compiler command line option /WX: Treats all warnings as errors
9631 - update a list of source files, included into the project
9633 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9634 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9635 changed project type to Generic Project so that can be correcly converted to VS.NET project
9637 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9639 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9641 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9643 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9644 added return 0 statements after assert() to make compiler happy
9646 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9647 added newline in the def file to keep MSC compiler satisfied
9649 * sdcc/src/z80/gen.c:
9650 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9651 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9652 - solved MSC error in function aopDump()
9654 * sdcc_vc.h: define PREFIX as "\\sdcc"
9656 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9657 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9705 Added -p option. Allows port dependent processor to be specified.
9708 Initialized the new field char *Processor field to NULL in all ports
9711 Compiler generated registers for interrupt context saving
9712 were not getting allocated.
9714 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9717 Fixed left shift. Will promote the left side of a left shift
9718 if a) left shifting more than size of operand or b) when assigned
9719 to something size > size of left side
9721 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9723 tons of changes. Register allocation has been

9829 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9831 * sdcc/src/SDCCloop.c:
9832 Previous fix was not good. basic blocks that have "break" or "return" are
9833 not really partof a loop , but live ranges used in these blocks should
9834 be live thru the entire loop, so set partOfLoop but don't add them to
9837 2002-02-21 <johan AT FRIJA>
9839 * src/SDCCcse.c: fixed bug #514308
9841 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

9845 statement inside a loop, it was not being considered part of the loop.
9847 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9849 2002-02-10 Karl Bongers <karl AT turbobit.com>
9852 Fixed up SDCDB debugger somewhat. Updated debugger/README
9853 with lots of comments and notes.
9855 * device/examples/test2.c:
