31 * src/ds390/peeph.def: disabled 186.d and 227.a as fix for #1434401
32 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
34 2006-03-06 Borut Razem <borut.razem AT siol.net>
36 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
39 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
41 * src/pic16/gen.c (genPcall): fixed bug #1443644
42 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
43 which dumps before the function entry point a data byte which represents
44 the number of the local variables used by the specified function, added
45 'xinst' for initial support for Extended Instruction Support,
46 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
47 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
48 port->fun_prefix anymore (may change later),

50 _main (this should take care the --main-return command line option in
52 (genOr): removed some legacy pic-port instructions,
53 * src/pic16/genarith.c (genAddLit): re-enabled old code because
54 performing operations with SFR's causes data to be written more than
55 once to each SFR. Perhaps SFRs should be handled in special cases...
56 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
58 * src/pic16/main.c (_process_pragma): stack bound checking did not take
59 into account for stack starting position,

61 --extended or -y for Extended Instruction Support,
62 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
63 (deassignLRs): *** perhaps the most important change, old 'for' code
64 (commented out for reference), didn't account for some registers which
65 were left marked 'not free' after a pointer operation. The change
66 reduces register usage a lot in some cases

2341 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2342 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2343 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2344 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2345 always available in leading double underscore form. The C99 support is
2346 mostly missing, but it's a start.
2347 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2348 reserved identifier "__data".

2426 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2428 * device/lib/printf_large.c: removed inline assembly for portability and
2429 readability. Use printf_fast if speed or size are more important.
2430 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2431 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2433 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2435 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2436 prevent compiler warning
2438 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2440 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2441 moved to level 0 and declared as static. Also they are explicit
2442 placed in access bank. This was necessery because some times they
2443 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2444 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2445 optimizations. Currently only compare to unsigned char is implemented,
2446 * src/pic16/gen.c: added fReturnIdx array,
2447 * (struct resolvedIfx) is moved to gen.h and made public,
2448 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2449 * (aopForSym): added an optimization to directly store in stack of
2450 the operand of a SEND iCode,
2451 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2452 but as registers instead (AOP_REG) using the fReturnIdx array,
2453 * (pic16_freeAsmop): remove the freed register from the
2454 _G.sregsAlloc field,
2455 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2456 a compare of 'WREG',
2457 * (pic16_popGetTempRegCond): changed function prototype, now
2458 function takes also a bitVector argument v which holds the current
2459 set of registers that are allocated for stack access by aopForSym,
2460 registers allocated in aopForSym for accessing stack symbols are not
2461 any more part of the functions usedRegs field,
2462 * (genCall): some times aopOp is called for a stack variable to be
2463 send, aopForSym might perform the push, if this is true make sure
2464 that genCall doesn't push the variable twice by testing _G.resDirect,
2465 * (genFunction): changed testing for unspecified interrupt number
2466 from 256 to INTNO_UNSPEC,
2467 * modified selection scheme of frame pointer generation. Previously
2468 if function did use local registers a frame pointer was generated,
2469 now a frame pointer is generated only if function has arguments
2470 (that need PLUSW2 register access), or has stack arguments, or the
2471 compiler is not instructed to omit the frame pointer,
2472 * (genEndFunction): before restoring local registers that were saved
2473 in the function preamble, also restore the registers that *might*
2474 have been allocated for stack access,
2475 * (genRet): removed some old comments,
2476 * (genCmp, the active (RN's) version): added a call to the
2477 pic16_genCmp_special function to perform the compare with a more
2478 robust and optimized way,
2479 * (genInline): a feature has been added in inline code generation,
2480 which allows a wildcard variable substitution when writing inline
2481 assembly. Code is incomplete and experimental therefore undocumented,
2482 * (genCast): changed order of aopOp for result and right to allow
2483 aopForSym to directly load the result if possible,
2484 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2485 perform an optimized compare on some selected special occasions,
2486 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2487 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2488 generate an IVT any more,
2489 * src/pic16/main.c (pic16_optionsTable): added command line option
2491 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2492 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2494 * src/pic16/NOTES: Raphael Neider added in list of active developers
2495 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2496 jumptable_end to prevent bug #,
2497 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2498 inCond and outCond fields,
2499 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2500 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2501 turn off register spilling,
2502 * (packRegsForOneUse): synced with other ports' versions although it
2503 is not used currently,
2504 * (pic16_packRegisters): added an optimization while reading
2505 structure bitfields, some registers may be saved (malloc code is
2506 decreased by 80 bytes)
2508 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2510 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2511 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2512 this can be optimized more?
2514 2005-03-10 Raphael Neider <rneider AT web.de>
2516 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2517 genNearPointerGet): (hopefully) fixed access to bitfields via
2518 pointers (p->bitN = x; and x = p->bitN; failed)
2520 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2563 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
2564 to keep the correct label reference count when adding/removing references
2565 to labels. A peephole file using this is appended to patch #1144962.

3152 Adding support for replacing ljmps with sjmps in jumptables
3153 generated for switch statements. For now you need to set the
3154 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3155 Now 4 algorithms for mcs51 jumptable generation are used:
3156 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3157 addresses loaded pc-relative for up to 112 cases and stack-pushing
3158 target addresses loaded with offset from dptr for up to 256 cases.

3188 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3190 * added libc directory. The current version of LibC contains string
3191 functions, ctype functions and macros and some functions of the
3192 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3193 be extensively tested in the future. Standard disclaimer here.
3194 Library is not automatically build yet. But one can build it by
3195 invoking 'make' inside the libc directory.

3206 * (pic16_storeForReturn): optimized return of 0,
3207 * (genCmp): experimental code for new genCmp which uses PIC18's
3208 special compare&skip instructions. Initial tests fail some times
3209 with variables grater than 1 byte in size, so new code is disabled,
3210 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3212 * (genCast): began a fix to optimize the casting of a bit to another
3213 bit, now assigning a bitfield to another bitfield will fail, sorry,

3222 and 1 for banking instruction,
3223 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3224 caused stop processing pCodes after a inline assembly block,
3225 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3227 registers when it shouldn't,
3228 * src/pic16/ralloc.c (allocReg): add preliminary support for
3229 supporting a limited set of temporary registers,
3231 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3233 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

3237 (genFunction): optimize RECEIVE iCodes in reentrant functions
3239 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6122 virus/worm forged address usage.
6124 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
6126 Fixed promotion, it should be done on AST level:

6150 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
6152 * src/SDCCast.c: added an additional type flow in decorateType() of
6153 opposite direction, see feature request #860006; it's enabled at runtime
6154 by setting the environment variable SDCC_NEWTYPEFLOW
6155 * src/SDCCast.h: changed prototype of decorateType()
6156 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
6157 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
6158 'char' to 'int' can be omitted, if both operands are 'unsigned char';

6189 added support for multiple code pages and multiple RAM banks on the
6190 PIC 14 port. The ASM files now no longer simply assume all the
6191 code / RAM are in the same page / bank. This means the linker can
6192 safely allocate code/RAM of separate ASM files to different pages/banks.
6193 * doc/sdccman.lyx: added Slade's tips
6194 * src/mcs51/peeph.def: fixed bug #880768

6236 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6238 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6239 loaded with the linker search paths (-L arguments) and the libraries
6240 to be linked with the current source (-l arguments). Changes
6241 currently will affect only the pic16 port.
6242 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6243 include path the port specific paths and port specific libraries,
6244 * gplink command now contains the $3 argument,
6245 * src/pic16/device.h,
6246 * src/pic16/device.c,: structure PIC_device is made public and
6247 renamed to PIC16_device, the same for variable Pics which is renamed

6262 Documenting changes from previous commits.
6263 * configure.in (version 1.56),
6264 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6265 when generating output files to configure the pic16 library,
6266 but now I've commented it out, since gputils aren't installed in the
6267 SF compile farm, so library won't compile
6269 * device/lib/Makefile.in (version 1.56): initially I've added in
6270 target 'all' the prerequestive 'model-pic16' so it compiled the
6271 pic16 library, but now I've commented it out for the same reasons
6273 * added targets 'model-pic16' and 'objects-pic16' to compile the
6275 * added target 'port-specific-objects-pic16' to handle the
6276 generated libraries and copy them into the build/ directory
6277 * added target 'clean-intermediate-pic16' to clean intermediate
6278 files into pic16 directory
6279 * in target 'installdirs' added line to create directory pic16 in
6280 the installation path
6282 * device/include/Makefile.in (version 1.11): in target 'install'
6283 added lines to copy all header files to installation path,
6284 * in target 'installdirs' added line create directory for pic16
6285 headers in the installation path

6300 * src/z80/main.c (_parseOptions): fixed the portmode= command line
6301 option so that it actually works. Made it specific to the z80, since
6302 the gbz80 doesn't have these kinds of I/O ports.
6304 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6306 * device/include/z180.h,

6330 via literal number. The symbol is placed in the corresponding
6331 position of the data ram
6332 * (pic16_dump_section): relocatable and absolute uninitialized
6333 data are now emitted in sorted order to reduce section naming,
6334 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6335 weren't marked as being in the access bank,
6337 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6339 Added portion of GNU PIC Library under the directory
6340 device/include/pic16 and device/lib/pic16. These files
6341 contain the declarations of SFRs for the PIC18Fxx2 devices.
6342 The directory is initialized via configure from toplevel.

6372 all over. Telling LaTeX to be less strict with word spacing
6373 to better keep the right margin. Changed some notes about
6374 maintainance of the ports in section 3.2.1 - is it OK like this?

6570 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6572 PIC16 port related changes:
6573 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6574 added variable stackPos,
6576 * gen.c: genCall, assignResultValue: added support for
6577 pushing/retrieving function parameters to/from stack,
6578 genFunction,genEndFunction: setup stack frame for the
6580 genAddrOf: will be changed according to bug 863624
6582 * added files genutils.c and genutils.h which contain gen*
6583 debugged and optimised functions extracted from gen.c
6585 * glue.c: added variable 'externs' which holds extern symbols,
6586 pic16emitRegularMap: is modified to properly handle relocatable
6587 symbols under the new scheme,
6588 pic16createInterruptVect: is modified
6589 pic16printPublics: is modified to emit 'global' assembler directives,
6590 added pic16_printExterns to print extern symbols,
6591 pic16glue: initializes stack/frame pointer in the beginning of
6592 the assembly output. Temporary hack, will be corrected later,
6593 because gplink yet does not support stack and SDCC does not
6594 yet support a type of crt0.o object to create the final binary.
6596 * Removed many lines that contain 8051 legacy code.
6597 * The code is finally placed under a 'code' directive.
6598 * Added port specific options.
6600 * _process_pragma: simplified since now we do not need *special*
6601 include file to define SFR registers. But a separate header
6602 will be needed. This will be developed later.
6603 * _pic16_parseOptions: added, parses port specific options:
6604 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6605 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6606 --preplace-udata-with=
6608 * _pic16_setDefaultOptions: modified to initialize section names,
6609 but hack is temporarly out of order since it needs improvement.
6610 * _pic16_genAssemblerPreamble: configuration words are emitted by
6611 their address instead of their name. This part is incomplete and
6612 supports only the 18Fxx2 devices. Other devices will emit an error
6613 during assembly since they do not contain the same set of config
6615 * _pic16_genIVT: is modified,
6617 * pcode.c: added definitions for some hardware registers that are needed
6619 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6620 All PCI entries are updated. Now LFSR is supported.
6621 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6622 * added pic16_newpCodeOpLit2 to support instructions with
6623 two literal arguments
6624 * pic16_pCode2str: corrected code that emits assembler instructions
6625 with two literal operands and those that have an access bit modifier
6626 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6627 this fixes a bug which caused some labels to be lost, when an
6628 assembler directive was added, i.e. banksel,
6629 * pic16_FixRegisterBanking: improved logic that causes the insertion
6631 * InlineFunction: functions that are called once, are not any more
6632 inlined. This can be a port option in the future,
6634 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6636 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6637 hold the corresponding uninitialized symbols,
6638 * pic16_allocProcessorRegister: registers have explicit marked the
6640 * pic16_allocInternalRegister: registers are explicit marked as
6642 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6643 processing list, so bit registers were lost,
6646 * ralloc.h: added field 'accessBank' and original symbol operand
6647 in register definition,
6648 * removed the field isMapped from register definition,
6650 ** Several functions have been removed from various sources:
6651 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6652 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6653 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6654 pic16_assignRelocatableRegisters
6656 ** others have been introduced:
6657 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6658 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6660 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6662 * support/scripts/inc2h.pl: changed definition of BIT_AT
6663 to emit 'sbit at' instead of 'bit at'. This was a request.
6665 PIC16 port related preliminary changes:
6666 * gen.c: prefixed function popRegFromString with
6667 pic16_ and all references to it corrected
6668 * pcode.c: all pic16_pc_* hardware registers prefixed
6669 with underscore (_),
6670 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6671 * ralloc.c: newReg(): when register is REG_SFR then
6672 set address to rIdx,
6673 pic16_allocProcessorRegister(): marks register wasUsed=0
6674 pic16_writeUsedRegs(): added a call to assign processor
6675 registers via pic16_assignFixedRegisters
6677 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6679 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6680 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6681 variables in unused register banks. Also the SSEG is placed
6682 wherever there is enough space for it, and IDATA can be anywhere
6683 in internal RAM. For now compile using -Wl-Y[stack_size].
6684 The mem file is different for this option as well, since it
6685 makes no sense of talking about DSEG lenght.
6687 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6689 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6690 in certain cases, e.g. when ROM assignment, patch provided
6691 from Albert den Haan.

6932 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6934 * src/SDCCast.c (decorateType): disabled a transformation I added in
6935 revision 1.188 (access to fields of a structure at an absolute address);
6936 it breaks with bitfields, extern declarations, and gcse analysis.
6937 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6938 could be assigned through a pointer, so don't complain.
6939 * src/SDCCast.c (astErrors),

7043 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
7044 uninitialized variables) for the mcs51. Set environment variable
7045 SDCC_GENRAMCLEAR to test.
7046 xdata initialization slightly shorter
7048 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7697 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7698 copied from genNearPointerSet()
7699 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7700 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7716 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7717 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7718 type for bits was changed. It resulted in bit variables becoming

7736 A few small changes that speed up the peephole optimizer.
7740 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7742 Try to make the peephole optimizer smarter by maintaining
7743 an association between the assembly source code and the
7744 iCodes that originated them. Put this information to use
7745 with a new peephole rule condition "notVolatile" so that
7746 the rules can be aggressive yet still safe.
7751 * src/mcs51/peeph.def
7753 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7757 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7758 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7759 if the left or right operand symbols have the accuse flag set.
7761 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7763 Changed the type of the result of the ! (NOT) operator to char;
7764 previously it returned the same type as the source. This allows
7765 us to eliminate all the genFloatNot functions (all of its target
7766 implementations were very buggy) since !float can use the same

7778 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7779 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7780 during interrupts. Ensure WSAVE is located at a shared bank address.
7781 2. Fixed page selection in some places
7782 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7783 the registers name strings.
7784 4. Fixed "signed / unsigned compare" compiler warnings.
7785 5. The PIC port manages its own allocation of the general purpose
7786 registers, but makes no attempt to reuse them. As a result when
7787 compiling it soon runs out of general purpose registers. Some
7788 additional code was added to the files pcode.c and device.c to walk
7789 through the function call tree and rename the registers so that they
7799 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7806 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7808 Made bitfield a distinct type from bit so that bitfields
7809 convert as per ANSI C and bits retain their traditional
7810 boolean style behaviour. Implemented bitfield support in
7818 * src/ds390/gen.c: bit v bitfield split
7819 * src/z80/gen.c: New support for bitfields
7820 * support/regression/tests/bitfields.c: reenabled z80,
7823 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7825 Rules 246.x, 247.x relate to bitfields, the others speed up
7826 access to xdata mapped I/O devices.
7828 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7830 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7832 Cleaned up genPackBits and genUnpackBits and added two helper
7833 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7834 for literal assignments in genPackBits (thanks to Frieder for
7840 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7842 Fixed bug #748310 (pointer to function type mishandled when the
7843 function name is omitted). Also fixed a SIGSEGV when a function
7844 attribute (reentrant, etc) is used on a non-function or on a
7845 function but misplaced before the parameter list.
7847 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7849 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7850 * support/Util/SDCCerr.h,

7872 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7874 Made the constant following the "interrupt" keyword optional. If
7875 omitted, the function will not automatically be given an entry
7876 in the interrupt vector table (similar to #pragma NOIV, but
7877 less syntacticly kludgy). The interrupt number is also now
7878 range checked. Also fixed a bug in the high order bit example

7892 * src/SDCCicode.c (operandOperation): rewritten some ops
7893 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7894 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7896 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7897 be re-activated by defining REDUCE_LITERALS)
7898 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7899 unsigned, but are signed by default
7900 * src/SDCCval.c (constVal): rearranged
7901 * src/SDCCval.c (valMod): preliminary fix
7902 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8357 Using pdflatex this will give you a hyperlinked pdf file with
8358 bookmarks. (prepend '%' before /usepackage if this breaks something)

8407 * src/SDCCmain.c: linkOptions is changed to set *,
8408 added if/endif conditional macros to remove options help
8409 messages from optionsTable when a port is not configured, added
8410 support for the PIc16 port in the ports table, when executing
8411 the compiler with no port specified on command line, a default
8412 port is selected with the new macro DEFAULT_PORT which is
8413 defined in port.h, in setDefaultOptions() linkOptions is removed
8414 from initialization assignment, since now it is a set,
8415 parseCmdLine uses setParseWithComma for linkOptions, in
8416 linkEdit() linkOptions are accessed with new function indexSet()
8417 which returns the i'th item of a set variable. See SDCCset.c, in
8418 linkEdit() when calling buildCmdLine(), added linkOptions as
8419 last argument. Now users can pass arguments to gplink via the
8420 -Wl option, main() uses pic16glue() to glue up pic16 programs

8432 * src/pic16/glue.c: commented out some error producing lines
8433 * src/pic16/main.c: __config directives are commented out to stop
8434 gpasm complaining and test the linkage with gplink, _linkCmd and
8435 _asmCmd changed to be more gplink and gpasm friendly
8436 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8437 produced an error when parsed, peep rule 12 is added to utilize
8438 movff, but it is commented out since the pCode does not support
8439 yet a command with 2 address arguments
8441 2003-05-18 <johan AT balder>
8443 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
8444 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8470 2003-05-11 Borut Razem <borut.razem AT siol.net>
8472 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8473 the path of bin directory, so that PATH is the only env. variable, which has to be set
8474 in case of standard installation.
8475 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9522 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9525 2002-09-18 <wiml AT hhhh.org>
9527 * SDCClrange.h: exposed setFromRange() and setToRange()
9528 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9529 packRegsForAccUse() (bug 542397)
9530 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9531 multiple times and emitting the fetch operations more than once
9532 added aopGetUsesAcc() function to allow binary operators to
9533 fetch their operands in the correct order; made genMinus() emit
9534 compact code for X = LITERAL - Y
9536 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9537 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9538 sprintf() in line 1267.
9540 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9541 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9544 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9545 Changes to aslink (All the changes are marked with 'JCF'):
9547 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9550 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9551 area BSEG. Also moves, if possible, the DATA area down into the internal
9552 ram so more space is available.
9554 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9557 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9558 not bytes. Function summary() which creates a memory usage summary
9559 file with extension .mem. Reports of overlaping stack and small stack
9560 size. If the space for the stack is less than 16 bytes aslink trows a
9563 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9564 the 8051. Option 'y' for memory summary output file.
9566 Changes to sdcc (All the changes are marked with 'JCF'):
9568 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9570 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9571 overlaying area for it (uses RegBankUsed[4]).
9573 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9574 bank zero as used by default. By default aslink locates the stack
9575 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9576 the creation of the .mem file. Delegates the allocation of data area
9577 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9578 the begining of the stack area to aslink.
9580 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9581 glue() in SDCCglue.c creates an area for it.
9583 2002-09-03 Borut Razem <borut.razem AT siol.net>
9584 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9585 sdcc/src/pic/glue.c:
9586 introduced atexit() handler for teporay files removal in case of
9587 errors, assertions, ...
9589 2002-08-29 Borut Razem <borut.razem AT siol.net>
9590 * sdcc/support/cpp2/auto-host_vc_in.h:
9591 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9592 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9593 Maybe there is a similar problem with BORLANDC? It should be checked!
9595 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9596 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9597 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9598 was not executed, and the compiler (cl) launched a warning:
9599 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9601 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9602 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9604 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9605 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9607 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9608 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9609 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9610 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9611 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9612 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9613 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9614 - added Release configuration in VS projects
9615 - review of compiler an linker options
9616 - VC .exe files are generated in bin_vc directory, not to interfere
9617 with binaries generated from other projects (cygwin, mingw, bcc ...)
9619 * sdcc/src/yacc.dsp: added
9621 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9622 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9623 and insert the version number definitions from .version
9625 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9627 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9628 added - genarate auto-host.h using auto-host_vc_in.h as template
9631 removed from CVS, generated automatically
9633 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9634 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9636 2002-08-11 Borut Razem <borut.razem AT siol.net>
9637 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9639 2002-08-10 Borut Razem <borut.razem AT siol.net>
9640 * src/SDCCmain.c (main):
9641 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9642 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9643 The consequence was that some temporary files were not removed.
9646 unification of code in functions tempfilename() and tempfile():
9647 function tempnam() is defined in Visual Studio 6.0 and .NET
9649 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9651 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9652 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9653 - removed compiler command line option /WX: Treats all warnings as errors
9654 - update a list of source files, included into the project
9656 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9657 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9658 changed project type to Generic Project so that can be correcly converted to VS.NET project
9660 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9662 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9664 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9666 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9667 added return 0 statements after assert() to make compiler happy
9669 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9670 added newline in the def file to keep MSC compiler satisfied
9672 * sdcc/src/z80/gen.c:
9673 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9674 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9675 - solved MSC error in function aopDump()
9677 * sdcc_vc.h: define PREFIX as "\\sdcc"
9679 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9680 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9683 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9684 - Rewrote the register banking algorithm.
9685 - Added pCode live-range analysis to registers (for now, only non-used and
9686 singly-used registers optimized away)
9688 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

9719 2002-03-28 Johan Knol <johan AT balder>
9721 * src/SDCCval.c: fixed bug #532436
9723 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9725 Added "char *Processor" field to the port structure.
9728 Added -p option. Allows port dependent processor to be specified.
9731 Initialized the new field char *Processor field to NULL in all ports
9734 Compiler generated registers for interrupt context saving
9735 were not getting allocated.
9737 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9740 Fixed left shift. Will promote the left side of a left shift
9741 if a) left shifting more than size of operand or b) when assigned
9742 to something size > size of left side
9744 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9746 tons of changes. Register allocation has been
9747 rewritten. Added customization for the various PICs. Flow

9852 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9854 * sdcc/src/SDCCloop.c:
9855 Previous fix was not good. basic blocks that have "break" or "return" are
9856 not really partof a loop , but live ranges used in these blocks should
9857 be live thru the entire loop, so set partOfLoop but don't add them to
9860 2002-02-21 <johan AT FRIJA>
9862 * src/SDCCcse.c: fixed bug #514308
9864 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9867 Fixed BUG #519583. If a conditional block ended in a return/break
9868 statement inside a loop, it was not being considered part of the loop.
9870 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9872 2002-02-10 Karl Bongers <karl AT turbobit.com>
9875 Fixed up SDCDB debugger somewhat. Updated debugger/README
9876 with lots of comments and notes.
9878 * device/examples/test2.c:
9879 Fix bug, "red" variable not being initialized(compiler complained).
9881 * device/examples/Makefile, examples/test3.c:

9883 for use as a multiple module SDCDB test case.
9885 * sim/ucsim/cmd.src/cmdset.cc:
9886 Took out debug printfs in ucsim "next" command.
9889 Karl and Johan start ucsim XA support. Most dissassembly working,

9930 set preprocessor defines (depending on options)
9932 * src/SDCCicode.c, src/SDCCicode.h:
9933 changes made to handle multiple sends & receives
9936 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
