45 implemented patch 1120823 Thanks to Willy De la Court (normal
46 interrupts need an interrupt number now if they are made critical),
47 and enabled nesting of critical functions though not for gbz80

57 archive with gcc 4.1 on mips and wrote the patch"
59 2006-03-16 Raphael Neider <rneider AT web.de>
61 * src/pic16/genarith.c (genAddLit): simplified and fixed case where

64 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
67 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
69 * src/.version: increased version number to 2.5.5
70 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
71 linking is done manually in pic16 port's _linkEdit,
72 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
73 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

90 call to allocReg, not by manually allocating a new one,
91 (pic16_assignRegisters): now before going through the register
92 allocating functions mark all registers as free. This eliminates some
93 side effects resulting from peephole parser done earlier in the backbone

153 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
154 which dumps before the function entry point a data byte which represents
155 the number of the local variables used by the specified function, added
156 'xinst' for initial support for Extended Instruction Support,
157 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,

159 port->fun_prefix anymore (may change later),
160 (genFunction, genEndFunction): do not store/restore local registers for
161 _main (this should take care the --main-return command line option in
163 (genOr): removed some legacy pic-port instructions,
164 * src/pic16/genarith.c (genAddLit): re-enabled old code because
165 performing operations with SFR's causes data to be written more than
166 once to each SFR. Perhaps SFRs should be handled in special cases...
167 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
169 * src/pic16/main.c (_process_pragma): stack bound checking did not take
170 into account for stack starting position,
171 (struct OPTIONS pic16_optionsTable): added command line argument
172 --extended or -y for Extended Instruction Support,
173 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
174 (deassignLRs): *** perhaps the most important change, old 'for' code
175 (commented out for reference), didn't account for some registers which
176 were left marked 'not free' after a pointer operation. The change
177 reduces register usage a lot in some cases

2535 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2537 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2539 * device/lib/printf_large.c: removed inline assembly for portability and
2540 readability. Use printf_fast if speed or size are more important.
2541 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2542 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2544 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2546 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2547 prevent compiler warning
2549 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2551 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2552 moved to level 0 and declared as static. Also they are explicit
2553 placed in access bank. This was necessery because some times they
2554 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2555 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2556 optimizations. Currently only compare to unsigned char is implemented,
2557 * src/pic16/gen.c: added fReturnIdx array,
2558 * (struct resolvedIfx) is moved to gen.h and made public,
2559 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2560 * (aopForSym): added an optimization to directly store in stack of
2561 the operand of a SEND iCode,
2562 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2563 but as registers instead (AOP_REG) using the fReturnIdx array,
2564 * (pic16_freeAsmop): remove the freed register from the
2565 _G.sregsAlloc field,
2566 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2567 a compare of 'WREG',
2568 * (pic16_popGetTempRegCond): changed function prototype, now
2569 function takes also a bitVector argument v which holds the current
2570 set of registers that are allocated for stack access by aopForSym,
2571 registers allocated in aopForSym for accessing stack symbols are not
2572 any more part of the functions usedRegs field,
2573 * (genCall): some times aopOp is called for a stack variable to be
2574 send, aopForSym might perform the push, if this is true make sure
2575 that genCall doesn't push the variable twice by testing _G.resDirect,
2576 * (genFunction): changed testing for unspecified interrupt number
2577 from 256 to INTNO_UNSPEC,
2578 * modified selection scheme of frame pointer generation. Previously
2579 if function did use local registers a frame pointer was generated,
2580 now a frame pointer is generated only if function has arguments
2581 (that need PLUSW2 register access), or has stack arguments, or the
2582 compiler is not instructed to omit the frame pointer,
2583 * (genEndFunction): before restoring local registers that were saved
2584 in the function preamble, also restore the registers that *might*
2585 have been allocated for stack access,
2586 * (genRet): removed some old comments,
2587 * (genCmp, the active (RN's) version): added a call to the
2588 pic16_genCmp_special function to perform the compare with a more
2589 robust and optimized way,
2590 * (genInline): a feature has been added in inline code generation,
2591 which allows a wildcard variable substitution when writing inline
2592 assembly. Code is incomplete and experimental therefore undocumented,

3263 Adding support for replacing ljmps with sjmps in jumptables
3264 generated for switch statements. For now you need to set the
3265 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3266 Now 4 algorithms for mcs51 jumptable generation are used:
3267 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3268 addresses loaded pc-relative for up to 112 cases and stack-pushing
3269 target addresses loaded with offset from dptr for up to 256 cases.

3299 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3301 * added libc directory. The current version of LibC contains string
3302 functions, ctype functions and macros and some functions of the
3303 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3304 be extensively tested in the future. Standard disclaimer here.
3305 Library is not automatically build yet. But one can build it by
3306 invoking 'make' inside the libc directory.

3317 * (pic16_storeForReturn): optimized return of 0,
3318 * (genCmp): experimental code for new genCmp which uses PIC18's
3319 special compare&skip instructions. Initial tests fail some times
3320 with variables grater than 1 byte in size, so new code is disabled,
3321 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3323 * (genCast): began a fix to optimize the casting of a bit to another
3324 bit, now assigning a bitfield to another bitfield will fail, sorry,

3333 and 1 for banking instruction,
3334 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3335 caused stop processing pCodes after a inline assembly block,
3336 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3337 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3338 registers when it shouldn't,
3339 * src/pic16/ralloc.c (allocReg): add preliminary support for
3340 supporting a limited set of temporary registers,
3342 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3348 (genFunction): optimize RECEIVE iCodes in reentrant functions
3350 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6350 loaded with the linker search paths (-L arguments) and the libraries
6351 to be linked with the current source (-l arguments). Changes
6352 currently will affect only the pic16 port.
6353 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6354 include path the port specific paths and port specific libraries,
6355 * gplink command now contains the $3 argument,
6356 * src/pic16/device.h,

6373 Documenting changes from previous commits.
6374 * configure.in (version 1.56),
6375 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6376 when generating output files to configure the pic16 library,
6377 but now I've commented it out, since gputils aren't installed in the
6378 SF compile farm, so library won't compile
6380 * device/lib/Makefile.in (version 1.56): initially I've added in
6381 target 'all' the prerequestive 'model-pic16' so it compiled the
6382 pic16 library, but now I've commented it out for the same reasons
6384 * added targets 'model-pic16' and 'objects-pic16' to compile the
6386 * added target 'port-specific-objects-pic16' to handle the
6387 generated libraries and copy them into the build/ directory
6388 * added target 'clean-intermediate-pic16' to clean intermediate
6389 files into pic16 directory
6390 * in target 'installdirs' added line to create directory pic16 in

6635 * src/SDCCast.c (decorateType),
6636 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
6637 LEFT_OP (left shift)
6639 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6641 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6642 (default behaviour).
6644 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6646 A python script to validate compiler diagnostic messages. It can be
6647 used to verify that sdcc complains about bad c source code and
6648 gives a good location of the error.
6649 * support/valdiag/Makefile,
6650 * support/valdiag/valdiag.py,
6651 * support/valdiag/tests/*
6653 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6668 Bug reported from Jesus Calvino-Fraga
6670 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6672 * sdcc.spec: updated
6673 * device/include/Makefile.in: don't install CVS directories
6674 * device/lib/Makefile.in: added removal of CVS directories after install
6675 * doc/Makefile: fixed install, added local_icons
6676 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6677 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6678 * src/ds390/gen.c (genRightShift): fixed bug #870788

6681 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6683 PIC16 port related changes:
6684 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6685 added variable stackPos,
6687 * gen.c: genCall, assignResultValue: added support for
6688 pushing/retrieving function parameters to/from stack,
6689 genFunction,genEndFunction: setup stack frame for the
6691 genAddrOf: will be changed according to bug 863624
6693 * added files genutils.c and genutils.h which contain gen*
6694 debugged and optimised functions extracted from gen.c
6696 * glue.c: added variable 'externs' which holds extern symbols,
6697 pic16emitRegularMap: is modified to properly handle relocatable
6698 symbols under the new scheme,
6699 pic16createInterruptVect: is modified
6700 pic16printPublics: is modified to emit 'global' assembler directives,
6701 added pic16_printExterns to print extern symbols,
6702 pic16glue: initializes stack/frame pointer in the beginning of
6703 the assembly output. Temporary hack, will be corrected later,
6704 because gplink yet does not support stack and SDCC does not
6705 yet support a type of crt0.o object to create the final binary.
6707 * Removed many lines that contain 8051 legacy code.
6708 * The code is finally placed under a 'code' directive.
6709 * Added port specific options.
6711 * _process_pragma: simplified since now we do not need *special*
6712 include file to define SFR registers. But a separate header
6713 will be needed. This will be developed later.
6714 * _pic16_parseOptions: added, parses port specific options:
6715 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6716 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6717 --preplace-udata-with=
6719 * _pic16_setDefaultOptions: modified to initialize section names,
6720 but hack is temporarly out of order since it needs improvement.
6721 * _pic16_genAssemblerPreamble: configuration words are emitted by
6722 their address instead of their name. This part is incomplete and
6723 supports only the 18Fxx2 devices. Other devices will emit an error
6724 during assembly since they do not contain the same set of config
6726 * _pic16_genIVT: is modified,
6728 * pcode.c: added definitions for some hardware registers that are needed
6730 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6731 All PCI entries are updated. Now LFSR is supported.
6732 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6733 * added pic16_newpCodeOpLit2 to support instructions with
6734 two literal arguments
6735 * pic16_pCode2str: corrected code that emits assembler instructions
6736 with two literal operands and those that have an access bit modifier
6737 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6738 this fixes a bug which caused some labels to be lost, when an
6739 assembler directive was added, i.e. banksel,
6740 * pic16_FixRegisterBanking: improved logic that causes the insertion
6742 * InlineFunction: functions that are called once, are not any more
6743 inlined. This can be a port option in the future,
6745 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6747 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6748 hold the corresponding uninitialized symbols,
6749 * pic16_allocProcessorRegister: registers have explicit marked the
6751 * pic16_allocInternalRegister: registers are explicit marked as
6753 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6754 processing list, so bit registers were lost,
6757 * ralloc.h: added field 'accessBank' and original symbol operand
6758 in register definition,
6759 * removed the field isMapped from register definition,
6761 ** Several functions have been removed from various sources:
6762 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6763 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6764 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6765 pic16_assignRelocatableRegisters
6767 ** others have been introduced:
6768 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6769 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6771 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6773 * support/scripts/inc2h.pl: changed definition of BIT_AT
6774 to emit 'sbit at' instead of 'bit at'. This was a request.
6776 PIC16 port related preliminary changes:
6777 * gen.c: prefixed function popRegFromString with
6778 pic16_ and all references to it corrected
6779 * pcode.c: all pic16_pc_* hardware registers prefixed
6780 with underscore (_),
6781 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6782 * ralloc.c: newReg(): when register is REG_SFR then
6783 set address to rIdx,
6784 pic16_allocProcessorRegister(): marks register wasUsed=0
6785 pic16_writeUsedRegs(): added a call to assign processor
6786 registers via pic16_assignFixedRegisters
6788 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6790 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6791 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6792 variables in unused register banks. Also the SSEG is placed
6793 wherever there is enough space for it, and IDATA can be anywhere
6794 in internal RAM. For now compile using -Wl-Y[stack_size].
6795 The mem file is different for this option as well, since it
6796 makes no sense of talking about DSEG lenght.
6798 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6800 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6801 in certain cases, e.g. when ROM assignment, patch provided
6802 from Albert den Haan.

7043 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7045 * src/SDCCast.c (decorateType): disabled a transformation I added in
7046 revision 1.188 (access to fields of a structure at an absolute address);
7047 it breaks with bitfields, extern declarations, and gcse analysis.
7048 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7049 could be assigned through a pointer, so don't complain.
7050 * src/SDCCast.c (astErrors),
7052 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
7054 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

7806 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7807 fetching of the pointer
7808 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7809 copied from genNearPointerSet()
7810 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7811 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7827 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7828 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7829 type for bits was changed. It resulted in bit variables becoming
7830 global, which is not permitted in PIC 14 assembly output.
7832 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7847 A few small changes that speed up the peephole optimizer.
7851 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7853 Try to make the peephole optimizer smarter by maintaining
7854 an association between the assembly source code and the
7855 iCodes that originated them. Put this information to use
7856 with a new peephole rule condition "notVolatile" so that
7857 the rules can be aggressive yet still safe.
7862 * src/mcs51/peeph.def
7864 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7868 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7869 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7870 if the left or right operand symbols have the accuse flag set.
7872 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7874 Changed the type of the result of the ! (NOT) operator to char;
7875 previously it returned the same type as the source. This allows
7876 us to eliminate all the genFloatNot functions (all of its target
7877 implementations were very buggy) since !float can use the same
7880 * src/SDCCicode.c (ast2iCode): ! returns char

7889 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7890 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7891 during interrupts. Ensure WSAVE is located at a shared bank address.
7892 2. Fixed page selection in some places
7893 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7894 the registers name strings.
7895 4. Fixed "signed / unsigned compare" compiler warnings.
7896 5. The PIC port manages its own allocation of the general purpose
7897 registers, but makes no attempt to reuse them. As a result when
7898 compiling it soon runs out of general purpose registers. Some
7899 additional code was added to the files pcode.c and device.c to walk
7900 through the function call tree and rename the registers so that they
7910 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7911 genPlus() & genMinus() when the result is the same as left or right

7917 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7919 Made bitfield a distinct type from bit so that bitfields
7920 convert as per ANSI C and bits retain their traditional
7921 boolean style behaviour. Implemented bitfield support in
7929 * src/ds390/gen.c: bit v bitfield split
7930 * src/z80/gen.c: New support for bitfields
7931 * support/regression/tests/bitfields.c: reenabled z80,
7934 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7936 Rules 246.x, 247.x relate to bitfields, the others speed up
7937 access to xdata mapped I/O devices.
7939 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7941 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7943 Cleaned up genPackBits and genUnpackBits and added two helper
7944 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7945 for literal assignments in genPackBits (thanks to Frieder for
7951 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7953 Fixed bug #748310 (pointer to function type mishandled when the
7954 function name is omitted). Also fixed a SIGSEGV when a function
7955 attribute (reentrant, etc) is used on a non-function or on a
7956 function but misplaced before the parameter list.
7958 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7960 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

7983 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7985 Made the constant following the "interrupt" keyword optional. If
7986 omitted, the function will not automatically be given an entry
7987 in the interrupt vector table (similar to #pragma NOIV, but
7988 less syntacticly kludgy). The interrupt number is also now
7989 range checked. Also fixed a bug in the high order bit example

8520 messages from optionsTable when a port is not configured, added
8521 support for the PIc16 port in the ports table, when executing
8522 the compiler with no port specified on command line, a default
8523 port is selected with the new macro DEFAULT_PORT which is
8524 defined in port.h, in setDefaultOptions() linkOptions is removed
8525 from initialization assignment, since now it is a set,
8526 parseCmdLine uses setParseWithComma for linkOptions, in
8527 linkEdit() linkOptions are accessed with new function indexSet()
8528 which returns the i'th item of a set variable. See SDCCset.c, in
8529 linkEdit() when calling buildCmdLine(), added linkOptions as
8530 last argument. Now users can pass arguments to gplink via the
8531 -Wl option, main() uses pic16glue() to glue up pic16 programs

8545 gpasm complaining and test the linkage with gplink, _linkCmd and
8546 _asmCmd changed to be more gplink and gpasm friendly
8547 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8548 produced an error when parsed, peep rule 12 is added to utilize
8549 movff, but it is commented out since the pCode does not support
8550 yet a command with 2 address arguments
8552 2003-05-18 <johan AT balder>
8554 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9572 2003-01-07 <johan AT balder>
9574 * src/SDCCast.c (decorateType): fixed bug #600035
9576 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>

9587 2003-01-06 <johan AT balder>
9589 * src/SDCCicode.c: fixed array add
9591 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9592 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9593 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9595 2003-01-04 <johan AT balder>
9597 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9599 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9600 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9602 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9603 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

9612 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9613 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9615 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9617 * in \sdcc\as\mcs51\ changed these files in order to create an
9618 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9619 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9620 following files to include the previous two files: aslink.dsp,
9621 Makefile.aslink, Makefile.bcc, and Makefile.in.
9623 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9624 .adb instead of .cdb
9626 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9628 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9629 value from option --iram-size.
9631 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9633 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9636 2002-09-18 <wiml AT hhhh.org>
9638 * SDCClrange.h: exposed setFromRange() and setToRange()
9639 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9640 packRegsForAccUse() (bug 542397)
9641 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9642 multiple times and emitting the fetch operations more than once
9643 added aopGetUsesAcc() function to allow binary operators to
9644 fetch their operands in the correct order; made genMinus() emit
9645 compact code for X = LITERAL - Y
9647 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9648 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9649 sprintf() in line 1267.
9651 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9652 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9655 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9656 Changes to aslink (All the changes are marked with 'JCF'):
9658 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9661 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9662 area BSEG. Also moves, if possible, the DATA area down into the internal
9663 ram so more space is available.
9665 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9668 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9669 not bytes. Function summary() which creates a memory usage summary
9670 file with extension .mem. Reports of overlaping stack and small stack
9671 size. If the space for the stack is less than 16 bytes aslink trows a
9674 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9675 the 8051. Option 'y' for memory summary output file.
9677 Changes to sdcc (All the changes are marked with 'JCF'):
9679 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9681 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9682 overlaying area for it (uses RegBankUsed[4]).
9684 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9685 bank zero as used by default. By default aslink locates the stack
9686 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9687 the creation of the .mem file. Delegates the allocation of data area
9688 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9689 the begining of the stack area to aslink.
9691 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9692 glue() in SDCCglue.c creates an area for it.
9694 2002-09-03 Borut Razem <borut.razem AT siol.net>
9695 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9696 sdcc/src/pic/glue.c:
9697 introduced atexit() handler for teporay files removal in case of
9698 errors, assertions, ...
9700 2002-08-29 Borut Razem <borut.razem AT siol.net>
9701 * sdcc/support/cpp2/auto-host_vc_in.h:
9702 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9703 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9704 Maybe there is a similar problem with BORLANDC? It should be checked!
9706 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9707 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9708 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9709 was not executed, and the compiler (cl) launched a warning:
9710 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9712 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9713 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9715 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9716 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9718 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9719 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9720 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9721 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9722 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9723 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9724 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9725 - added Release configuration in VS projects
9726 - review of compiler an linker options
9727 - VC .exe files are generated in bin_vc directory, not to interfere
9728 with binaries generated from other projects (cygwin, mingw, bcc ...)
9730 * sdcc/src/yacc.dsp: added
9732 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9733 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9734 and insert the version number definitions from .version
9736 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9738 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9739 added - genarate auto-host.h using auto-host_vc_in.h as template
9742 removed from CVS, generated automatically
9744 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9745 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9747 2002-08-11 Borut Razem <borut.razem AT siol.net>
9748 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9750 2002-08-10 Borut Razem <borut.razem AT siol.net>
9751 * src/SDCCmain.c (main):
9752 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9753 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9754 The consequence was that some temporary files were not removed.
9757 unification of code in functions tempfilename() and tempfile():
9758 function tempnam() is defined in Visual Studio 6.0 and .NET
9760 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9762 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9763 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9764 - removed compiler command line option /WX: Treats all warnings as errors
9765 - update a list of source files, included into the project
9767 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9768 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9769 changed project type to Generic Project so that can be correcly converted to VS.NET project
9771 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9773 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9775 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9777 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9778 added return 0 statements after assert() to make compiler happy
9780 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9781 added newline in the def file to keep MSC compiler satisfied
9783 * sdcc/src/z80/gen.c:
9784 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9785 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9786 - solved MSC error in function aopDump()
9788 * sdcc_vc.h: define PREFIX as "\\sdcc"
9790 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9791 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9793 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9794 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9795 - Rewrote the register banking algorithm.
9796 - Added pCode live-range analysis to registers (for now, only non-used and
9797 singly-used registers optimized away)
9799 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9801 * 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.
9803 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9804 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9806 2002-04-22 Michael Hope <michaelh AT vroom>

9826 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9828 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9830 2002-03-28 Johan Knol <johan AT balder>
9832 * src/SDCCval.c: fixed bug #532436
9834 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9836 Added "char *Processor" field to the port structure.
9839 Added -p option. Allows port dependent processor to be specified.
9842 Initialized the new field char *Processor field to NULL in all ports
9845 Compiler generated registers for interrupt context saving
9846 were not getting allocated.
9848 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9851 Fixed left shift. Will promote the left side of a left shift
9852 if a) left shifting more than size of operand or b) when assigned
9853 to something size > size of left side
9855 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9857 tons of changes. Register allocation has been
9858 rewritten. Added customization for the various PICs. Flow
9859 analysis is restructured. ...
9865 Added. device.c is a PIC port hack to accomodate variations
9868 2002-03-13 Michael Hope <michaelh AT vroom>
9870 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9872 2002-03-04 johanknol <johanknol AT manik>
9874 * /src/SDCCval.c: fixed
9876 const unsigned char arr[][2] = { { 0, 1 } };

9879 2002-03-04 bela <bela AT manik>
9881 * /device/include/mcs51reg.h:
9882 ds89c420 register definition update

9963 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9965 * sdcc/src/SDCCloop.c:
9966 Previous fix was not good. basic blocks that have "break" or "return" are
9967 not really partof a loop , but live ranges used in these blocks should
9968 be live thru the entire loop, so set partOfLoop but don't add them to
9971 2002-02-21 <johan AT FRIJA>
9973 * src/SDCCcse.c: fixed bug #514308
9975 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9978 Fixed BUG #519583. If a conditional block ended in a return/break
9979 statement inside a loop, it was not being considered part of the loop.
9981 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9983 2002-02-10 Karl Bongers <karl AT turbobit.com>
9986 Fixed up SDCDB debugger somewhat. Updated debugger/README
9987 with lots of comments and notes.
9989 * device/examples/test2.c:
9990 Fix bug, "red" variable not being initialized(compiler complained).
9992 * device/examples/Makefile, examples/test3.c:
9993 Add Makefile in device/examples folder, compiles test3.c
9994 for use as a multiple module SDCDB test case.
9996 * sim/ucsim/cmd.src/cmdset.cc:
9997 Took out debug printfs in ucsim "next" command.
10000 Karl and Johan start ucsim XA support. Most dissassembly working,
10001 about 75% emulation done(plenty of work remaining).
10003 * sim/ucsim/z80.src:
10004 Add Z80 support to ucsim, add test-ucz80 regression test,
10005 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10006 Notice z80 compiler fails on examples/test3.c/crc code.
