41 implemented patch 1120823 Thanks to Willy De la Court (normal
42 interrupts need an interrupt number now if they are made critical),
43 and enabled nesting of critical functions though not for gbz80
44 (genCritical, genEndCritical): added functions
45 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
46 * src/z80/mappings.i: added "ei" to all mappings

50 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
51 submitted by the Debian SDCC maintainer Aurelien Jarno:
52 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
53 archive with gcc 4.1 on mips and wrote the patch"
55 2006-03-16 Raphael Neider <rneider AT web.de>
57 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
58 the left operand is shorter than the result (c* = lit-c* + int),
60 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
63 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
65 * src/.version: increased version number to 2.5.5
66 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
67 linking is done manually in pic16 port's _linkEdit,
68 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
69 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
70 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
71 allocate asmop as AOP_ACC,
72 (aopForRemat): added parameter 'bool result' in function declaration,

85 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
86 call to allocReg, not by manually allocating a new one,
87 (pic16_assignRegisters): now before going through the register
88 allocating functions mark all registers as free. This eliminates some
89 side effects resulting from peephole parser done earlier in the backbone
91 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
93 * src/SDCCicode.c (geniCodeLogic),

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

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

2450 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2451 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2452 always available in leading double underscore form. The C99 support is
2453 mostly missing, but it's a start.
2454 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2455 reserved identifier "__data".

2525 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
2528 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2530 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
2531 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2533 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2535 * device/lib/printf_large.c: removed inline assembly for portability and
2536 readability. Use printf_fast if speed or size are more important.
2537 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2538 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2540 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2542 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2543 prevent compiler warning
2545 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2547 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2548 moved to level 0 and declared as static. Also they are explicit
2549 placed in access bank. This was necessery because some times they
2550 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2551 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2552 optimizations. Currently only compare to unsigned char is implemented,
2553 * src/pic16/gen.c: added fReturnIdx array,
2554 * (struct resolvedIfx) is moved to gen.h and made public,
2555 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2556 * (aopForSym): added an optimization to directly store in stack of
2557 the operand of a SEND iCode,
2558 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2559 but as registers instead (AOP_REG) using the fReturnIdx array,
2560 * (pic16_freeAsmop): remove the freed register from the
2561 _G.sregsAlloc field,
2562 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2563 a compare of 'WREG',
2564 * (pic16_popGetTempRegCond): changed function prototype, now
2565 function takes also a bitVector argument v which holds the current
2566 set of registers that are allocated for stack access by aopForSym,
2567 registers allocated in aopForSym for accessing stack symbols are not
2568 any more part of the functions usedRegs field,
2569 * (genCall): some times aopOp is called for a stack variable to be
2570 send, aopForSym might perform the push, if this is true make sure
2571 that genCall doesn't push the variable twice by testing _G.resDirect,
2572 * (genFunction): changed testing for unspecified interrupt number
2573 from 256 to INTNO_UNSPEC,
2574 * modified selection scheme of frame pointer generation. Previously
2575 if function did use local registers a frame pointer was generated,
2576 now a frame pointer is generated only if function has arguments
2577 (that need PLUSW2 register access), or has stack arguments, or the
2578 compiler is not instructed to omit the frame pointer,
2579 * (genEndFunction): before restoring local registers that were saved
2580 in the function preamble, also restore the registers that *might*
2581 have been allocated for stack access,
2582 * (genRet): removed some old comments,
2583 * (genCmp, the active (RN's) version): added a call to the
2584 pic16_genCmp_special function to perform the compare with a more
2585 robust and optimized way,
2586 * (genInline): a feature has been added in inline code generation,
2587 which allows a wildcard variable substitution when writing inline
2588 assembly. Code is incomplete and experimental therefore undocumented,

3259 Adding support for replacing ljmps with sjmps in jumptables
3260 generated for switch statements. For now you need to set the
3261 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3262 Now 4 algorithms for mcs51 jumptable generation are used:
3263 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3264 addresses loaded pc-relative for up to 112 cases and stack-pushing
3265 target addresses loaded with offset from dptr for up to 256 cases.

3297 * added libc directory. The current version of LibC contains string
3298 functions, ctype functions and macros and some functions of the
3299 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3300 be extensively tested in the future. Standard disclaimer here.

3313 * (pic16_storeForReturn): optimized return of 0,
3314 * (genCmp): experimental code for new genCmp which uses PIC18's
3315 special compare&skip instructions. Initial tests fail some times
3316 with variables grater than 1 byte in size, so new code is disabled,
3317 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3319 * (genCast): began a fix to optimize the casting of a bit to another
3320 bit, now assigning a bitfield to another bitfield will fail, sorry,

3331 caused stop processing pCodes after a inline assembly block,
3332 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3334 registers when it shouldn't,
3335 * src/pic16/ralloc.c (allocReg): add preliminary support for
3336 supporting a limited set of temporary registers,
3338 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6346 loaded with the linker search paths (-L arguments) and the libraries
6347 to be linked with the current source (-l arguments). Changes
6348 currently will affect only the pic16 port.
6349 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6350 include path the port specific paths and port specific libraries,
6351 * gplink command now contains the $3 argument,
6352 * src/pic16/device.h,
6353 * src/pic16/device.c,: structure PIC_device is made public and

6369 Documenting changes from previous commits.
6370 * configure.in (version 1.56),
6371 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6372 when generating output files to configure the pic16 library,
6373 but now I've commented it out, since gputils aren't installed in the
6374 SF compile farm, so library won't compile
6376 * device/lib/Makefile.in (version 1.56): initially I've added in
6377 target 'all' the prerequestive 'model-pic16' so it compiled the
6378 pic16 library, but now I've commented it out for the same reasons
6380 * added targets 'model-pic16' and 'objects-pic16' to compile the
6382 * added target 'port-specific-objects-pic16' to handle the
6383 generated libraries and copy them into the build/ directory
6384 * added target 'clean-intermediate-pic16' to clean intermediate
6385 files into pic16 directory
6386 * in target 'installdirs' added line to create directory pic16 in

6631 * src/SDCCast.c (decorateType),
6632 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
6633 LEFT_OP (left shift)
6635 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6637 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6638 (default behaviour).
6640 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6642 A python script to validate compiler diagnostic messages. It can be
6643 used to verify that sdcc complains about bad c source code and
6644 gives a good location of the error.
6645 * support/valdiag/Makefile,
6646 * support/valdiag/valdiag.py,
6647 * support/valdiag/tests/*
6649 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6662 * src/common.h: added ifndef/define/endif macros
6663 around the header file.
6664 Bug reported from Jesus Calvino-Fraga
6666 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6668 * sdcc.spec: updated
6669 * device/include/Makefile.in: don't install CVS directories
6670 * device/lib/Makefile.in: added removal of CVS directories after install
6671 * doc/Makefile: fixed install, added local_icons
6672 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6673 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6674 * src/ds390/gen.c (genRightShift): fixed bug #870788

6677 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6679 PIC16 port related changes:
6680 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6681 added variable stackPos,
6683 * gen.c: genCall, assignResultValue: added support for
6684 pushing/retrieving function parameters to/from stack,
6685 genFunction,genEndFunction: setup stack frame for the
6687 genAddrOf: will be changed according to bug 863624
6689 * added files genutils.c and genutils.h which contain gen*
6690 debugged and optimised functions extracted from gen.c
6692 * glue.c: added variable 'externs' which holds extern symbols,
6693 pic16emitRegularMap: is modified to properly handle relocatable
6694 symbols under the new scheme,
6695 pic16createInterruptVect: is modified
6696 pic16printPublics: is modified to emit 'global' assembler directives,
6697 added pic16_printExterns to print extern symbols,
6698 pic16glue: initializes stack/frame pointer in the beginning of
6699 the assembly output. Temporary hack, will be corrected later,
6700 because gplink yet does not support stack and SDCC does not
6701 yet support a type of crt0.o object to create the final binary.
6703 * Removed many lines that contain 8051 legacy code.
6704 * The code is finally placed under a 'code' directive.
6705 * Added port specific options.
6707 * _process_pragma: simplified since now we do not need *special*
6708 include file to define SFR registers. But a separate header
6709 will be needed. This will be developed later.
6710 * _pic16_parseOptions: added, parses port specific options:
6711 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6712 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6713 --preplace-udata-with=
6715 * _pic16_setDefaultOptions: modified to initialize section names,
6716 but hack is temporarly out of order since it needs improvement.
6717 * _pic16_genAssemblerPreamble: configuration words are emitted by
6718 their address instead of their name. This part is incomplete and
6719 supports only the 18Fxx2 devices. Other devices will emit an error
6720 during assembly since they do not contain the same set of config
6722 * _pic16_genIVT: is modified,
6724 * pcode.c: added definitions for some hardware registers that are needed
6726 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6727 All PCI entries are updated. Now LFSR is supported.
6728 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6729 * added pic16_newpCodeOpLit2 to support instructions with
6730 two literal arguments
6731 * pic16_pCode2str: corrected code that emits assembler instructions
6732 with two literal operands and those that have an access bit modifier
6733 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6734 this fixes a bug which caused some labels to be lost, when an
6735 assembler directive was added, i.e. banksel,
6736 * pic16_FixRegisterBanking: improved logic that causes the insertion
6738 * InlineFunction: functions that are called once, are not any more
6739 inlined. This can be a port option in the future,
6741 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6743 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6744 hold the corresponding uninitialized symbols,
6745 * pic16_allocProcessorRegister: registers have explicit marked the
6747 * pic16_allocInternalRegister: registers are explicit marked as
6749 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6750 processing list, so bit registers were lost,
6753 * ralloc.h: added field 'accessBank' and original symbol operand
6754 in register definition,
6755 * removed the field isMapped from register definition,
6757 ** Several functions have been removed from various sources:
6758 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6759 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6760 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6761 pic16_assignRelocatableRegisters
6763 ** others have been introduced:
6764 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6765 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6767 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6769 * support/scripts/inc2h.pl: changed definition of BIT_AT
6770 to emit 'sbit at' instead of 'bit at'. This was a request.
6772 PIC16 port related preliminary changes:
6773 * gen.c: prefixed function popRegFromString with
6774 pic16_ and all references to it corrected
6775 * pcode.c: all pic16_pc_* hardware registers prefixed
6776 with underscore (_),
6777 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6778 * ralloc.c: newReg(): when register is REG_SFR then
6779 set address to rIdx,
6780 pic16_allocProcessorRegister(): marks register wasUsed=0
6781 pic16_writeUsedRegs(): added a call to assign processor
6782 registers via pic16_assignFixedRegisters
6784 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6786 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6787 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6788 variables in unused register banks. Also the SSEG is placed
6789 wherever there is enough space for it, and IDATA can be anywhere
6790 in internal RAM. For now compile using -Wl-Y[stack_size].
6791 The mem file is different for this option as well, since it
6792 makes no sense of talking about DSEG lenght.
6794 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6796 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6797 in certain cases, e.g. when ROM assignment, patch provided
6798 from Albert den Haan.

7039 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7041 * src/SDCCast.c (decorateType): disabled a transformation I added in
7042 revision 1.188 (access to fields of a structure at an absolute address);
7043 it breaks with bitfields, extern declarations, and gcse analysis.
7044 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7045 could be assigned through a pointer, so don't complain.
7046 * src/SDCCast.c (astErrors),
7048 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
7050 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

7801 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7802 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7803 fetching of the pointer
7804 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7805 copied from genNearPointerSet()
7806 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7807 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7808 If they pop r0/r1 they must be called in the opposite order than aopOp().
7809 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7810 (resp. --stack-auto), prepared for --xstack

7823 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7824 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7825 type for bits was changed. It resulted in bit variables becoming
7826 global, which is not permitted in PIC 14 assembly output.
7828 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7830 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7843 A few small changes that speed up the peephole optimizer.
7847 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7849 Try to make the peephole optimizer smarter by maintaining
7850 an association between the assembly source code and the
7851 iCodes that originated them. Put this information to use
7852 with a new peephole rule condition "notVolatile" so that
7853 the rules can be aggressive yet still safe.
7858 * src/mcs51/peeph.def
7860 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7864 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7865 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7866 if the left or right operand symbols have the accuse flag set.
7868 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7870 Changed the type of the result of the ! (NOT) operator to char;
7871 previously it returned the same type as the source. This allows
7872 us to eliminate all the genFloatNot functions (all of its target
7873 implementations were very buggy) since !float can use the same

7885 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7886 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7887 during interrupts. Ensure WSAVE is located at a shared bank address.
7888 2. Fixed page selection in some places
7889 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7890 the registers name strings.
7891 4. Fixed "signed / unsigned compare" compiler warnings.
7892 5. The PIC port manages its own allocation of the general purpose
7893 registers, but makes no attempt to reuse them. As a result when
7894 compiling it soon runs out of general purpose registers. Some
7895 additional code was added to the files pcode.c and device.c to walk
7896 through the function call tree and rename the registers so that they
7906 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

7913 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7915 Made bitfield a distinct type from bit so that bitfields
7916 convert as per ANSI C and bits retain their traditional
7917 boolean style behaviour. Implemented bitfield support in
7925 * src/ds390/gen.c: bit v bitfield split
7926 * src/z80/gen.c: New support for bitfields
7927 * support/regression/tests/bitfields.c: reenabled z80,
7930 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7932 Rules 246.x, 247.x relate to bitfields, the others speed up
7933 access to xdata mapped I/O devices.
7935 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7937 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7939 Cleaned up genPackBits and genUnpackBits and added two helper
7940 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7941 for literal assignments in genPackBits (thanks to Frieder for
7947 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7949 Fixed bug #748310 (pointer to function type mishandled when the
7950 function name is omitted). Also fixed a SIGSEGV when a function
7951 attribute (reentrant, etc) is used on a non-function or on a
7952 function but misplaced before the parameter list.
7954 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7956 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

7979 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7981 Made the constant following the "interrupt" keyword optional. If
7982 omitted, the function will not automatically be given an entry
7983 in the interrupt vector table (similar to #pragma NOIV, but
7984 less syntacticly kludgy). The interrupt number is also now
7985 range checked. Also fixed a bug in the high order bit example

8515 added if/endif conditional macros to remove options help
8516 messages from optionsTable when a port is not configured, added
8517 support for the PIc16 port in the ports table, when executing
8518 the compiler with no port specified on command line, a default
8519 port is selected with the new macro DEFAULT_PORT which is
8520 defined in port.h, in setDefaultOptions() linkOptions is removed
8521 from initialization assignment, since now it is a set,
8522 parseCmdLine uses setParseWithComma for linkOptions, in
8523 linkEdit() linkOptions are accessed with new function indexSet()
8524 which returns the i'th item of a set variable. See SDCCset.c, in
8525 linkEdit() when calling buildCmdLine(), added linkOptions as
8526 last argument. Now users can pass arguments to gplink via the
8527 -Wl option, main() uses pic16glue() to glue up pic16 programs

8541 gpasm complaining and test the linkage with gplink, _linkCmd and
8542 _asmCmd changed to be more gplink and gpasm friendly
8543 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8544 produced an error when parsed, peep rule 12 is added to utilize
8545 movff, but it is commented out since the pCode does not support
8546 yet a command with 2 address arguments
8548 2003-05-18 <johan AT balder>
8550 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9568 2003-01-07 <johan AT balder>
9570 * src/SDCCast.c (decorateType): fixed bug #600035
9572 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>

9583 2003-01-06 <johan AT balder>
9585 * src/SDCCicode.c: fixed array add
9587 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9588 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9589 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9591 2003-01-04 <johan AT balder>
9593 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9595 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9596 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9598 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

9608 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9609 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9611 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9613 * in \sdcc\as\mcs51\ changed these files in order to create an
9614 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9615 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9616 following files to include the previous two files: aslink.dsp,
9617 Makefile.aslink, Makefile.bcc, and Makefile.in.
9619 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9620 .adb instead of .cdb
9622 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9624 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9625 value from option --iram-size.
9627 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9629 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9632 2002-09-18 <wiml AT hhhh.org>
9634 * SDCClrange.h: exposed setFromRange() and setToRange()
9635 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9636 packRegsForAccUse() (bug 542397)
9637 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9638 multiple times and emitting the fetch operations more than once
9639 added aopGetUsesAcc() function to allow binary operators to
9640 fetch their operands in the correct order; made genMinus() emit
9641 compact code for X = LITERAL - Y
9643 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9644 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9645 sprintf() in line 1267.
9647 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9648 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9651 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9652 Changes to aslink (All the changes are marked with 'JCF'):
9654 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9657 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9658 area BSEG. Also moves, if possible, the DATA area down into the internal
9659 ram so more space is available.
9661 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9664 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9665 not bytes. Function summary() which creates a memory usage summary
9666 file with extension .mem. Reports of overlaping stack and small stack
9667 size. If the space for the stack is less than 16 bytes aslink trows a
9670 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9671 the 8051. Option 'y' for memory summary output file.
9673 Changes to sdcc (All the changes are marked with 'JCF'):
9675 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9677 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9678 overlaying area for it (uses RegBankUsed[4]).
9680 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9681 bank zero as used by default. By default aslink locates the stack
9682 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9683 the creation of the .mem file. Delegates the allocation of data area
9684 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9685 the begining of the stack area to aslink.
9687 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9688 glue() in SDCCglue.c creates an area for it.
9690 2002-09-03 Borut Razem <borut.razem AT siol.net>
9691 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9692 sdcc/src/pic/glue.c:
9693 introduced atexit() handler for teporay files removal in case of
9694 errors, assertions, ...
9696 2002-08-29 Borut Razem <borut.razem AT siol.net>
9697 * sdcc/support/cpp2/auto-host_vc_in.h:
9698 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9699 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9700 Maybe there is a similar problem with BORLANDC? It should be checked!
9702 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9703 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9704 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9705 was not executed, and the compiler (cl) launched a warning:
9706 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9708 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9709 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9711 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9712 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9714 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9715 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9716 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9717 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9718 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9719 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9720 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9721 - added Release configuration in VS projects
9722 - review of compiler an linker options
9723 - VC .exe files are generated in bin_vc directory, not to interfere
9724 with binaries generated from other projects (cygwin, mingw, bcc ...)
9726 * sdcc/src/yacc.dsp: added
9728 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9729 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9730 and insert the version number definitions from .version
9732 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9734 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9735 added - genarate auto-host.h using auto-host_vc_in.h as template
9738 removed from CVS, generated automatically
9740 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9741 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9743 2002-08-11 Borut Razem <borut.razem AT siol.net>
9744 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9746 2002-08-10 Borut Razem <borut.razem AT siol.net>
9747 * src/SDCCmain.c (main):
9748 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9749 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9750 The consequence was that some temporary files were not removed.
9753 unification of code in functions tempfilename() and tempfile():
9754 function tempnam() is defined in Visual Studio 6.0 and .NET
9756 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9758 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9759 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9760 - removed compiler command line option /WX: Treats all warnings as errors
9761 - update a list of source files, included into the project
9763 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9764 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9765 changed project type to Generic Project so that can be correcly converted to VS.NET project
9767 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9769 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9771 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9773 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9774 added return 0 statements after assert() to make compiler happy
9776 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9777 added newline in the def file to keep MSC compiler satisfied
9779 * sdcc/src/z80/gen.c:
9780 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9781 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9782 - solved MSC error in function aopDump()
9784 * sdcc_vc.h: define PREFIX as "\\sdcc"
9786 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9787 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9789 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9790 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9791 - Rewrote the register banking algorithm.
9792 - Added pCode live-range analysis to registers (for now, only non-used and
9793 singly-used registers optimized away)
9795 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9797 * 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.
9799 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9800 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9802 2002-04-22 Michael Hope <michaelh AT vroom>

9822 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9824 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9826 2002-03-28 Johan Knol <johan AT balder>
9828 * src/SDCCval.c: fixed bug #532436
9830 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9832 Added "char *Processor" field to the port structure.
9835 Added -p option. Allows port dependent processor to be specified.
9838 Initialized the new field char *Processor field to NULL in all ports
9841 Compiler generated registers for interrupt context saving
9842 were not getting allocated.
9844 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9847 Fixed left shift. Will promote the left side of a left shift
9848 if a) left shifting more than size of operand or b) when assigned
9849 to something size > size of left side
9851 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9853 tons of changes. Register allocation has been
9854 rewritten. Added customization for the various PICs. Flow
9855 analysis is restructured. ...
9861 Added. device.c is a PIC port hack to accomodate variations
9864 2002-03-13 Michael Hope <michaelh AT vroom>
9866 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9868 2002-03-04 johanknol <johanknol AT manik>
9870 * /src/SDCCval.c: fixed
9872 const unsigned char arr[][2] = { { 0, 1 } };
9873 t18.c:1: error: Initializer element is not constant
9875 2002-03-04 bela <bela AT manik>
9877 * /device/include/mcs51reg.h:
9878 ds89c420 register definition update
9880 2002-03-03 <johan AT FRIJA>

9959 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9961 * sdcc/src/SDCCloop.c:
9962 Previous fix was not good. basic blocks that have "break" or "return" are
9963 not really partof a loop , but live ranges used in these blocks should
9964 be live thru the entire loop, so set partOfLoop but don't add them to
9967 2002-02-21 <johan AT FRIJA>
9969 * src/SDCCcse.c: fixed bug #514308
9971 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9974 Fixed BUG #519583. If a conditional block ended in a return/break
9975 statement inside a loop, it was not being considered part of the loop.
9977 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9979 2002-02-10 Karl Bongers <karl AT turbobit.com>
9982 Fixed up SDCDB debugger somewhat. Updated debugger/README
9983 with lots of comments and notes.
9985 * device/examples/test2.c:
9986 Fix bug, "red" variable not being initialized(compiler complained).
9988 * device/examples/Makefile, examples/test3.c:
9989 Add Makefile in device/examples folder, compiles test3.c
9990 for use as a multiple module SDCDB test case.
9992 * sim/ucsim/cmd.src/cmdset.cc:
9993 Took out debug printfs in ucsim "next" command.
9996 Karl and Johan start ucsim XA support. Most dissassembly working,
9997 about 75% emulation done(plenty of work remaining).
9999 * sim/ucsim/z80.src:
10000 Add Z80 support to ucsim, add test-ucz80 regression test,
10001 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10002 Notice z80 compiler fails on examples/test3.c/crc code.
10004 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
