34 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
35 implemented patch 1120823 Thanks to Willy De la Court (normal
36 interrupts need an interrupt number now if they are made critical),
37 and enabled nesting of critical functions though not for gbz80
38 (genCritical, genEndCritical): added functions
39 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
40 * src/z80/mappings.i: added "ei" to all mappings
42 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
44 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
45 submitted by the Debian SDCC maintainer Aurelien Jarno:
46 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
47 archive with gcc 4.1 on mips and wrote the patch"
49 2006-03-16 Raphael Neider <rneider AT web.de>
51 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
52 the left operand is shorter than the result (c* = lit-c* + int),
54 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
57 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
59 * src/.version: increased version number to 2.5.5
60 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
61 linking is done manually in pic16 port's _linkEdit,
62 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
63 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
64 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
65 allocate asmop as AOP_ACC,
66 (aopForRemat): added parameter 'bool result' in function declaration,

79 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
80 call to allocReg, not by manually allocating a new one,
81 (pic16_assignRegisters): now before going through the register
82 allocating functions mark all registers as free. This eliminates some
83 side effects resulting from peephole parser done earlier in the backbone
85 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
87 * src/SDCCicode.c (geniCodeLogic),

106 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
107 (aopForSym, aopOp): increment asmop.allocated if reused,
108 (freeAsmop): decrement asmop.allocated and check for zero instead of
110 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
111 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

143 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
144 which dumps before the function entry point a data byte which represents
145 the number of the local variables used by the specified function, added
146 'xinst' for initial support for Extended Instruction Support,
147 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
148 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
149 port->fun_prefix anymore (may change later),
150 (genFunction, genEndFunction): do not store/restore local registers for
151 _main (this should take care the --main-return command line option in
153 (genOr): removed some legacy pic-port instructions,
154 * src/pic16/genarith.c (genAddLit): re-enabled old code because
155 performing operations with SFR's causes data to be written more than
156 once to each SFR. Perhaps SFRs should be handled in special cases...
157 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
159 * src/pic16/main.c (_process_pragma): stack bound checking did not take
160 into account for stack starting position,
161 (struct OPTIONS pic16_optionsTable): added command line argument
162 --extended or -y for Extended Instruction Support,
163 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
164 (deassignLRs): *** perhaps the most important change, old 'for' code
165 (commented out for reference), didn't account for some registers which
166 were left marked 'not free' after a pointer operation. The change
167 reduces register usage a lot in some cases

2448 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2449 reserved identifier "__data".
2451 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

2525 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2527 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2529 * device/lib/printf_large.c: removed inline assembly for portability and
2530 readability. Use printf_fast if speed or size are more important.
2531 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2532 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2534 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2536 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2537 prevent compiler warning
2539 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2541 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2542 moved to level 0 and declared as static. Also they are explicit
2543 placed in access bank. This was necessery because some times they
2544 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2545 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2546 optimizations. Currently only compare to unsigned char is implemented,
2547 * src/pic16/gen.c: added fReturnIdx array,
2548 * (struct resolvedIfx) is moved to gen.h and made public,
2549 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2550 * (aopForSym): added an optimization to directly store in stack of
2551 the operand of a SEND iCode,
2552 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2553 but as registers instead (AOP_REG) using the fReturnIdx array,
2554 * (pic16_freeAsmop): remove the freed register from the
2555 _G.sregsAlloc field,
2556 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2557 a compare of 'WREG',
2558 * (pic16_popGetTempRegCond): changed function prototype, now
2559 function takes also a bitVector argument v which holds the current
2560 set of registers that are allocated for stack access by aopForSym,
2561 registers allocated in aopForSym for accessing stack symbols are not
2562 any more part of the functions usedRegs field,
2563 * (genCall): some times aopOp is called for a stack variable to be
2564 send, aopForSym might perform the push, if this is true make sure
2565 that genCall doesn't push the variable twice by testing _G.resDirect,
2566 * (genFunction): changed testing for unspecified interrupt number
2567 from 256 to INTNO_UNSPEC,
2568 * modified selection scheme of frame pointer generation. Previously
2569 if function did use local registers a frame pointer was generated,
2570 now a frame pointer is generated only if function has arguments
2571 (that need PLUSW2 register access), or has stack arguments, or the
2572 compiler is not instructed to omit the frame pointer,
2573 * (genEndFunction): before restoring local registers that were saved
2574 in the function preamble, also restore the registers that *might*
2575 have been allocated for stack access,
2576 * (genRet): removed some old comments,
2577 * (genCmp, the active (RN's) version): added a call to the
2578 pic16_genCmp_special function to perform the compare with a more
2579 robust and optimized way,
2580 * (genInline): a feature has been added in inline code generation,
2581 which allows a wildcard variable substitution when writing inline
2582 assembly. Code is incomplete and experimental therefore undocumented,
2583 * (genCast): changed order of aopOp for result and right to allow
2584 aopForSym to directly load the result if possible,

3253 Adding support for replacing ljmps with sjmps in jumptables
3254 generated for switch statements. For now you need to set the
3255 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3256 Now 4 algorithms for mcs51 jumptable generation are used:
3257 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3258 addresses loaded pc-relative for up to 112 cases and stack-pushing
3259 target addresses loaded with offset from dptr for up to 256 cases.

3289 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3291 * added libc directory. The current version of LibC contains string
3292 functions, ctype functions and macros and some functions of the
3293 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3294 be extensively tested in the future. Standard disclaimer here.
3295 Library is not automatically build yet. But one can build it by
3296 invoking 'make' inside the libc directory.

3307 * (pic16_storeForReturn): optimized return of 0,
3308 * (genCmp): experimental code for new genCmp which uses PIC18's
3309 special compare&skip instructions. Initial tests fail some times
3310 with variables grater than 1 byte in size, so new code is disabled,
3311 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3313 * (genCast): began a fix to optimize the casting of a bit to another
3314 bit, now assigning a bitfield to another bitfield will fail, sorry,

3323 and 1 for banking instruction,
3324 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3325 caused stop processing pCodes after a inline assembly block,
3326 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3328 registers when it shouldn't,
3329 * src/pic16/ralloc.c (allocReg): add preliminary support for
3330 supporting a limited set of temporary registers,
3332 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3338 (genFunction): optimize RECEIVE iCodes in reentrant functions
3340 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6340 loaded with the linker search paths (-L arguments) and the libraries
6341 to be linked with the current source (-l arguments). Changes
6342 currently will affect only the pic16 port.
6343 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6344 include path the port specific paths and port specific libraries,
6345 * gplink command now contains the $3 argument,
6346 * src/pic16/device.h,

6363 Documenting changes from previous commits.
6364 * configure.in (version 1.56),
6365 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6366 when generating output files to configure the pic16 library,
6367 but now I've commented it out, since gputils aren't installed in the
6368 SF compile farm, so library won't compile
6370 * device/lib/Makefile.in (version 1.56): initially I've added in
6371 target 'all' the prerequestive 'model-pic16' so it compiled the
6372 pic16 library, but now I've commented it out for the same reasons
6374 * added targets 'model-pic16' and 'objects-pic16' to compile the
6376 * added target 'port-specific-objects-pic16' to handle the
6377 generated libraries and copy them into the build/ directory
6378 * added target 'clean-intermediate-pic16' to clean intermediate
6379 files into pic16 directory
6380 * in target 'installdirs' added line to create directory pic16 in

6384 added lines to copy all header files to installation path,
6385 * in target 'installdirs' added line create directory for pic16
6386 headers in the installation path

6625 * src/SDCCast.c (decorateType),
6626 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
6627 LEFT_OP (left shift)
6629 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6631 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6632 (default behaviour).
6634 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6636 A python script to validate compiler diagnostic messages. It can be
6637 used to verify that sdcc complains about bad c source code and
6638 gives a good location of the error.
6639 * support/valdiag/Makefile,
6640 * support/valdiag/valdiag.py,
6641 * support/valdiag/tests/*

6656 * src/common.h: added ifndef/define/endif macros
6657 around the header file.
6658 Bug reported from Jesus Calvino-Fraga
6660 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6662 * sdcc.spec: updated
6663 * device/include/Makefile.in: don't install CVS directories
6664 * device/lib/Makefile.in: added removal of CVS directories after install
6665 * doc/Makefile: fixed install, added local_icons
6666 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6667 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6668 * src/ds390/gen.c (genRightShift): fixed bug #870788

6671 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6673 PIC16 port related changes:
6674 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6675 added variable stackPos,
6677 * gen.c: genCall, assignResultValue: added support for
6678 pushing/retrieving function parameters to/from stack,
6679 genFunction,genEndFunction: setup stack frame for the
6681 genAddrOf: will be changed according to bug 863624
6683 * added files genutils.c and genutils.h which contain gen*
6684 debugged and optimised functions extracted from gen.c
6686 * glue.c: added variable 'externs' which holds extern symbols,
6687 pic16emitRegularMap: is modified to properly handle relocatable
6688 symbols under the new scheme,
6689 pic16createInterruptVect: is modified
6690 pic16printPublics: is modified to emit 'global' assembler directives,
6691 added pic16_printExterns to print extern symbols,
6692 pic16glue: initializes stack/frame pointer in the beginning of
6693 the assembly output. Temporary hack, will be corrected later,
6694 because gplink yet does not support stack and SDCC does not
6695 yet support a type of crt0.o object to create the final binary.
6697 * Removed many lines that contain 8051 legacy code.
6698 * The code is finally placed under a 'code' directive.
6699 * Added port specific options.
6701 * _process_pragma: simplified since now we do not need *special*
6702 include file to define SFR registers. But a separate header
6703 will be needed. This will be developed later.
6704 * _pic16_parseOptions: added, parses port specific options:
6705 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6706 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6707 --preplace-udata-with=
6709 * _pic16_setDefaultOptions: modified to initialize section names,
6710 but hack is temporarly out of order since it needs improvement.
6711 * _pic16_genAssemblerPreamble: configuration words are emitted by
6712 their address instead of their name. This part is incomplete and
6713 supports only the 18Fxx2 devices. Other devices will emit an error
6714 during assembly since they do not contain the same set of config
6716 * _pic16_genIVT: is modified,
6718 * pcode.c: added definitions for some hardware registers that are needed
6720 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6721 All PCI entries are updated. Now LFSR is supported.
6722 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6723 * added pic16_newpCodeOpLit2 to support instructions with
6724 two literal arguments
6725 * pic16_pCode2str: corrected code that emits assembler instructions
6726 with two literal operands and those that have an access bit modifier
6727 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6728 this fixes a bug which caused some labels to be lost, when an
6729 assembler directive was added, i.e. banksel,
6730 * pic16_FixRegisterBanking: improved logic that causes the insertion
6732 * InlineFunction: functions that are called once, are not any more
6733 inlined. This can be a port option in the future,
6735 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6737 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6738 hold the corresponding uninitialized symbols,
6739 * pic16_allocProcessorRegister: registers have explicit marked the
6741 * pic16_allocInternalRegister: registers are explicit marked as
6743 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6744 processing list, so bit registers were lost,
6747 * ralloc.h: added field 'accessBank' and original symbol operand
6748 in register definition,
6749 * removed the field isMapped from register definition,
6751 ** Several functions have been removed from various sources:
6752 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6753 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6754 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6755 pic16_assignRelocatableRegisters
6757 ** others have been introduced:
6758 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6759 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6761 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6763 * support/scripts/inc2h.pl: changed definition of BIT_AT
6764 to emit 'sbit at' instead of 'bit at'. This was a request.
6766 PIC16 port related preliminary changes:
6767 * gen.c: prefixed function popRegFromString with
6768 pic16_ and all references to it corrected
6769 * pcode.c: all pic16_pc_* hardware registers prefixed
6770 with underscore (_),
6771 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6772 * ralloc.c: newReg(): when register is REG_SFR then
6773 set address to rIdx,
6774 pic16_allocProcessorRegister(): marks register wasUsed=0
6775 pic16_writeUsedRegs(): added a call to assign processor
6776 registers via pic16_assignFixedRegisters
6778 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6780 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6781 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6782 variables in unused register banks. Also the SSEG is placed
6783 wherever there is enough space for it, and IDATA can be anywhere
6784 in internal RAM. For now compile using -Wl-Y[stack_size].
6785 The mem file is different for this option as well, since it
6786 makes no sense of talking about DSEG lenght.
6788 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6790 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6791 in certain cases, e.g. when ROM assignment, patch provided
6792 from Albert den Haan.

7033 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7035 * src/SDCCast.c (decorateType): disabled a transformation I added in
7036 revision 1.188 (access to fields of a structure at an absolute address);
7037 it breaks with bitfields, extern declarations, and gcse analysis.
7038 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7039 could be assigned through a pointer, so don't complain.
7040 * src/SDCCast.c (astErrors),
7042 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
7044 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

7050 pre-processor macro, i.e. -DMCU=p18f452
7051 * src/pic16/ralloc.c: renamed packRegisters to pic16_packRegisters,
7052 and modified to handle 'cast' icode similarly to '=' icode

7680 support for standard C idiom of memory mapped variables; for
7681 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7682 to xdata int at 0x1234 tempvar = 1.

7795 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7796 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7797 fetching of the pointer
7798 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7799 copied from genNearPointerSet()
7800 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7801 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7802 If they pop r0/r1 they must be called in the opposite order than aopOp().
7803 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7804 (resp. --stack-auto), prepared for --xstack

7817 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7818 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7819 type for bits was changed. It resulted in bit variables becoming
7820 global, which is not permitted in PIC 14 assembly output.
7822 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7824 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7837 A few small changes that speed up the peephole optimizer.
7841 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7843 Try to make the peephole optimizer smarter by maintaining
7844 an association between the assembly source code and the
7845 iCodes that originated them. Put this information to use
7846 with a new peephole rule condition "notVolatile" so that
7847 the rules can be aggressive yet still safe.
7852 * src/mcs51/peeph.def
7854 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7858 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7859 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7860 if the left or right operand symbols have the accuse flag set.
7862 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7864 Changed the type of the result of the ! (NOT) operator to char;
7865 previously it returned the same type as the source. This allows
7866 us to eliminate all the genFloatNot functions (all of its target
7867 implementations were very buggy) since !float can use the same

7880 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7881 during interrupts. Ensure WSAVE is located at a shared bank address.
7882 2. Fixed page selection in some places
7883 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7884 the registers name strings.
7885 4. Fixed "signed / unsigned compare" compiler warnings.
7886 5. The PIC port manages its own allocation of the general purpose
7887 registers, but makes no attempt to reuse them. As a result when
7888 compiling it soon runs out of general purpose registers. Some
7889 additional code was added to the files pcode.c and device.c to walk
7890 through the function call tree and rename the registers so that they
7900 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7907 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7909 Made bitfield a distinct type from bit so that bitfields
7910 convert as per ANSI C and bits retain their traditional
7911 boolean style behaviour. Implemented bitfield support in
7919 * src/ds390/gen.c: bit v bitfield split
7920 * src/z80/gen.c: New support for bitfields
7921 * support/regression/tests/bitfields.c: reenabled z80,
7924 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7926 Rules 246.x, 247.x relate to bitfields, the others speed up
7927 access to xdata mapped I/O devices.
7929 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7931 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7933 Cleaned up genPackBits and genUnpackBits and added two helper
7934 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7935 for literal assignments in genPackBits (thanks to Frieder for
7941 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7943 Fixed bug #748310 (pointer to function type mishandled when the
7944 function name is omitted). Also fixed a SIGSEGV when a function
7945 attribute (reentrant, etc) is used on a non-function or on a
7946 function but misplaced before the parameter list.
7948 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7950 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7951 * support/Util/SDCCerr.h,

7973 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7975 Made the constant following the "interrupt" keyword optional. If
7976 omitted, the function will not automatically be given an entry
7977 in the interrupt vector table (similar to #pragma NOIV, but
7978 less syntacticly kludgy). The interrupt number is also now
7979 range checked. Also fixed a bug in the high order bit example

8510 messages from optionsTable when a port is not configured, added
8511 support for the PIc16 port in the ports table, when executing
8512 the compiler with no port specified on command line, a default
8513 port is selected with the new macro DEFAULT_PORT which is
8514 defined in port.h, in setDefaultOptions() linkOptions is removed
8515 from initialization assignment, since now it is a set,
8516 parseCmdLine uses setParseWithComma for linkOptions, in
8517 linkEdit() linkOptions are accessed with new function indexSet()
8518 which returns the i'th item of a set variable. See SDCCset.c, in
8519 linkEdit() when calling buildCmdLine(), added linkOptions as
8520 last argument. Now users can pass arguments to gplink via the
8521 -Wl option, main() uses pic16glue() to glue up pic16 programs

8535 gpasm complaining and test the linkage with gplink, _linkCmd and
8536 _asmCmd changed to be more gplink and gpasm friendly
8537 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8538 produced an error when parsed, peep rule 12 is added to utilize
8539 movff, but it is commented out since the pCode does not support
8540 yet a command with 2 address arguments
8542 2003-05-18 <johan AT balder>
8544 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9579 * src/SDCCicode.c: fixed array add
9581 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9582 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9583 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9585 2003-01-04 <johan AT balder>
9587 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9589 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9590 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9592 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9593 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9602 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9603 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9605 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9607 * in \sdcc\as\mcs51\ changed these files in order to create an
9608 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9609 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9610 following files to include the previous two files: aslink.dsp,
9611 Makefile.aslink, Makefile.bcc, and Makefile.in.
9613 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9614 .adb instead of .cdb
9616 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9618 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9619 value from option --iram-size.
9621 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9623 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9626 2002-09-18 <wiml AT hhhh.org>
9628 * SDCClrange.h: exposed setFromRange() and setToRange()
9629 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9630 packRegsForAccUse() (bug 542397)
9631 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9632 multiple times and emitting the fetch operations more than once
9633 added aopGetUsesAcc() function to allow binary operators to
9634 fetch their operands in the correct order; made genMinus() emit
9635 compact code for X = LITERAL - Y
9637 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9638 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9639 sprintf() in line 1267.
9641 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9642 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9645 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9646 Changes to aslink (All the changes are marked with 'JCF'):
9648 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9651 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9652 area BSEG. Also moves, if possible, the DATA area down into the internal
9653 ram so more space is available.
9655 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9658 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9659 not bytes. Function summary() which creates a memory usage summary
9660 file with extension .mem. Reports of overlaping stack and small stack
9661 size. If the space for the stack is less than 16 bytes aslink trows a
9664 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9665 the 8051. Option 'y' for memory summary output file.
9667 Changes to sdcc (All the changes are marked with 'JCF'):
9669 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9671 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9672 overlaying area for it (uses RegBankUsed[4]).
9674 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9675 bank zero as used by default. By default aslink locates the stack
9676 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9677 the creation of the .mem file. Delegates the allocation of data area
9678 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9679 the begining of the stack area to aslink.
9681 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9682 glue() in SDCCglue.c creates an area for it.
9684 2002-09-03 Borut Razem <borut.razem AT siol.net>
9685 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9686 sdcc/src/pic/glue.c:
9687 introduced atexit() handler for teporay files removal in case of
9688 errors, assertions, ...
9690 2002-08-29 Borut Razem <borut.razem AT siol.net>
9691 * sdcc/support/cpp2/auto-host_vc_in.h:
9692 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9693 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9694 Maybe there is a similar problem with BORLANDC? It should be checked!
9696 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9697 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9698 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9699 was not executed, and the compiler (cl) launched a warning:
9700 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9702 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9703 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9705 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9706 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9708 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9709 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9710 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9711 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9712 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9713 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9714 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9715 - added Release configuration in VS projects
9716 - review of compiler an linker options
9717 - VC .exe files are generated in bin_vc directory, not to interfere
9718 with binaries generated from other projects (cygwin, mingw, bcc ...)
9720 * sdcc/src/yacc.dsp: added
9722 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9723 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9724 and insert the version number definitions from .version
9726 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9728 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9729 added - genarate auto-host.h using auto-host_vc_in.h as template
9732 removed from CVS, generated automatically
9734 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9735 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9737 2002-08-11 Borut Razem <borut.razem AT siol.net>
9738 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9740 2002-08-10 Borut Razem <borut.razem AT siol.net>
9741 * src/SDCCmain.c (main):
9742 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9743 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9744 The consequence was that some temporary files were not removed.
9747 unification of code in functions tempfilename() and tempfile():
9748 function tempnam() is defined in Visual Studio 6.0 and .NET
9750 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9752 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9753 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9754 - removed compiler command line option /WX: Treats all warnings as errors
9755 - update a list of source files, included into the project
9757 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9758 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9759 changed project type to Generic Project so that can be correcly converted to VS.NET project
9761 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9763 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9765 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9767 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9768 added return 0 statements after assert() to make compiler happy
9770 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9771 added newline in the def file to keep MSC compiler satisfied
9773 * sdcc/src/z80/gen.c:
9774 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9775 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9776 - solved MSC error in function aopDump()
9778 * sdcc_vc.h: define PREFIX as "\\sdcc"
9780 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9781 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

9784 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9785 - Rewrote the register banking algorithm.
9786 - Added pCode live-range analysis to registers (for now, only non-used and
9787 singly-used registers optimized away)
9789 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9791 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
9793 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9794 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9796 2002-04-22 Michael Hope <michaelh AT vroom>

9818 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9820 2002-03-28 Johan Knol <johan AT balder>
9822 * src/SDCCval.c: fixed bug #532436
9824 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9826 Added "char *Processor" field to the port structure.
9829 Added -p option. Allows port dependent processor to be specified.
9832 Initialized the new field char *Processor field to NULL in all ports
9835 Compiler generated registers for interrupt context saving
9836 were not getting allocated.
9838 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9841 Fixed left shift. Will promote the left side of a left shift
9842 if a) left shifting more than size of operand or b) when assigned
9843 to something size > size of left side
9845 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9847 tons of changes. Register allocation has been
9848 rewritten. Added customization for the various PICs. Flow
9849 analysis is restructured. ...
9855 Added. device.c is a PIC port hack to accomodate variations
9858 2002-03-13 Michael Hope <michaelh AT vroom>
9860 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9862 2002-03-04 johanknol <johanknol AT manik>
9864 * /src/SDCCval.c: fixed
9866 const unsigned char arr[][2] = { { 0, 1 } };
9867 t18.c:1: error: Initializer element is not constant
9869 2002-03-04 bela <bela AT manik>
9871 * /device/include/mcs51reg.h:
9872 ds89c420 register definition update
9874 2002-03-03 <johan AT FRIJA>

9953 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9955 * sdcc/src/SDCCloop.c:
9956 Previous fix was not good. basic blocks that have "break" or "return" are
9957 not really partof a loop , but live ranges used in these blocks should
9958 be live thru the entire loop, so set partOfLoop but don't add them to
9961 2002-02-21 <johan AT FRIJA>
9963 * src/SDCCcse.c: fixed bug #514308
9965 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9968 Fixed BUG #519583. If a conditional block ended in a return/break
9969 statement inside a loop, it was not being considered part of the loop.
9971 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9973 2002-02-10 Karl Bongers <karl AT turbobit.com>
9976 Fixed up SDCDB debugger somewhat. Updated debugger/README
9977 with lots of comments and notes.
9979 * device/examples/test2.c:
9980 Fix bug, "red" variable not being initialized(compiler complained).
9982 * device/examples/Makefile, examples/test3.c:
9983 Add Makefile in device/examples folder, compiles test3.c
9984 for use as a multiple module SDCDB test case.
9986 * sim/ucsim/cmd.src/cmdset.cc:
9987 Took out debug printfs in ucsim "next" command.
9990 Karl and Johan start ucsim XA support. Most dissassembly working,
9991 about 75% emulation done(plenty of work remaining).
9993 * sim/ucsim/z80.src:
9994 Add Z80 support to ucsim, add test-ucz80 regression test,
9995 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
9996 Notice z80 compiler fails on examples/test3.c/crc code.
9998 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
