3021 Enabled VPATH feature: changed nearly all Makefiles (149 files).
3022 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
3024 One basic decision: e.g. src/clean.mk includes further files. In order
3025 to make this work there are two solutions:
3026 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
3027 run configure on them. This way they can use
3028 'include $(srcdir)/port-clean.mk'
3029 - always include clean.mk by the Makefile at the same level. To avoid
3030 that `make clean` tries to include and build Makefile.dep the
3031 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
3032 implemented, because now even `make uninstall` doesn't create
3033 Makefile.in. clean.mk could be eliminated by pasting it in
3036 * debugger/mcs51/Makefile.in: build own objects from library sources
3037 (SLIB, SDCC) in current directory
3039 * configure, configure.in: renamed --disable-device-lib-build in

3302 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
3304 * src/mcs51/gen.c (genCall): fixed bug 1457608
3306 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3325 implemented patch 1120823 Thanks to Willy De la Court (normal
3326 interrupts need an interrupt number now if they are made critical),
3327 and enabled nesting of critical functions though not for gbz80
3328 (genCritical, genEndCritical): added functions
3329 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3330 * src/z80/mappings.i: added "ei" to all mappings

3339 2006-03-16 Raphael Neider <rneider AT web.de>
3341 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
3342 the left operand is shorter than the result (c* = lit-c* + int),
3344 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3347 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3349 * src/.version: increased version number to 2.5.5
3350 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3351 linking is done manually in pic16 port's _linkEdit,
3352 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3353 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3354 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3355 allocate asmop as AOP_ACC,
3356 (aopForRemat): added parameter 'bool result' in function declaration,
3357 (pic16_aopGet): return AOP_ACC when accessing WREG,
3358 (pic16_popGetTempReg): minor modification,

3369 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3370 call to allocReg, not by manually allocating a new one,
3371 (pic16_assignRegisters): now before going through the register
3372 allocating functions mark all registers as free. This eliminates some
3373 side effects resulting from peephole parser done earlier in the backbone
3375 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
3377 * src/SDCCicode.c (geniCodeLogic),

3423 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
3425 2006-03-06 Borut Razem <borut.razem AT siol.net>
3427 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3428 made the linker quiet
3430 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
3432 * src/pic16/gen.c (genPcall): fixed bug #1443644
3433 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3434 which dumps before the function entry point a data byte which represents
3435 the number of the local variables used by the specified function, added
3436 'xinst' for initial support for Extended Instruction Support,
3437 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3438 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3439 port->fun_prefix anymore (may change later),
3440 (genFunction, genEndFunction): do not store/restore local registers for
3441 _main (this should take care the --main-return command line option in
3443 (genOr): removed some legacy pic-port instructions,
3444 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3445 performing operations with SFR's causes data to be written more than
3446 once to each SFR. Perhaps SFRs should be handled in special cases...
3447 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3449 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3450 into account for stack starting position,
3451 (struct OPTIONS pic16_optionsTable): added command line argument
3452 --extended or -y for Extended Instruction Support,
3453 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3454 (deassignLRs): *** perhaps the most important change, old 'for' code
3455 (commented out for reference), didn't account for some registers which
3456 were left marked 'not free' after a pointer operation. The change
3457 reduces register usage a lot in some cases
3459 2006-03-04 Borut Razem <borut.razem AT siol.net>

5732 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5733 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5734 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5735 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5736 always available in leading double underscore form. The C99 support is
5737 mostly missing, but it's a start.
5738 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5739 reserved identifier "__data".

5817 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5819 * device/lib/printf_large.c: removed inline assembly for portability and
5820 readability. Use printf_fast if speed or size are more important.
5821 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5822 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5824 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5826 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5827 prevent compiler warning
5829 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5831 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5832 moved to level 0 and declared as static. Also they are explicit
5833 placed in access bank. This was necessery because some times they
5834 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5835 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5836 optimizations. Currently only compare to unsigned char is implemented,
5837 * src/pic16/gen.c: added fReturnIdx array,
5838 * (struct resolvedIfx) is moved to gen.h and made public,
5839 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5840 * (aopForSym): added an optimization to directly store in stack of
5841 the operand of a SEND iCode,
5842 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5843 but as registers instead (AOP_REG) using the fReturnIdx array,
5844 * (pic16_freeAsmop): remove the freed register from the
5845 _G.sregsAlloc field,
5846 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5847 a compare of 'WREG',
5848 * (pic16_popGetTempRegCond): changed function prototype, now
5849 function takes also a bitVector argument v which holds the current
5850 set of registers that are allocated for stack access by aopForSym,
5851 registers allocated in aopForSym for accessing stack symbols are not
5852 any more part of the functions usedRegs field,
5853 * (genCall): some times aopOp is called for a stack variable to be
5854 send, aopForSym might perform the push, if this is true make sure
5855 that genCall doesn't push the variable twice by testing _G.resDirect,
5856 * (genFunction): changed testing for unspecified interrupt number
5857 from 256 to INTNO_UNSPEC,
5858 * modified selection scheme of frame pointer generation. Previously
5859 if function did use local registers a frame pointer was generated,
5860 now a frame pointer is generated only if function has arguments
5861 (that need PLUSW2 register access), or has stack arguments, or the
5862 compiler is not instructed to omit the frame pointer,
5863 * (genEndFunction): before restoring local registers that were saved
5864 in the function preamble, also restore the registers that *might*
5865 have been allocated for stack access,
5866 * (genRet): removed some old comments,
5867 * (genCmp, the active (RN's) version): added a call to the
5868 pic16_genCmp_special function to perform the compare with a more
5869 robust and optimized way,
5870 * (genInline): a feature has been added in inline code generation,
5871 which allows a wildcard variable substitution when writing inline
5872 assembly. Code is incomplete and experimental therefore undocumented,
5873 * (genCast): changed order of aopOp for result and right to allow
5874 aopForSym to directly load the result if possible,
5875 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5876 perform an optimized compare on some selected special occasions,
5877 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5878 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5879 generate an IVT any more,
5880 * src/pic16/main.c (pic16_optionsTable): added command line option
5882 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5883 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5885 * src/pic16/NOTES: Raphael Neider added in list of active developers
5886 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5887 jumptable_end to prevent bug #,
5888 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5889 inCond and outCond fields,
5890 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5891 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5892 turn off register spilling,
5893 * (packRegsForOneUse): synced with other ports' versions although it
5894 is not used currently,
5895 * (pic16_packRegisters): added an optimization while reading
5896 structure bitfields, some registers may be saved (malloc code is
5897 decreased by 80 bytes)
5899 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5901 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5902 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5903 this can be optimized more?
5905 2005-03-10 Raphael Neider <rneider AT web.de>
5907 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5908 genNearPointerGet): (hopefully) fixed access to bitfields via
5909 pointers (p->bitN = x; and x = p->bitN; failed)

5955 to keep the correct label reference count when adding/removing references
5956 to labels. A peephole file using this is appended to patch #1144962.

6543 Adding support for replacing ljmps with sjmps in jumptables
6544 generated for switch statements. For now you need to set the
6545 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6546 Now 4 algorithms for mcs51 jumptable generation are used:
6547 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6548 addresses loaded pc-relative for up to 112 cases and stack-pushing
6549 target addresses loaded with offset from dptr for up to 256 cases.

6579 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6581 * added libc directory. The current version of LibC contains string
6582 functions, ctype functions and macros and some functions of the
6583 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6584 be extensively tested in the future. Standard disclaimer here.
6585 Library is not automatically build yet. But one can build it by
6586 invoking 'make' inside the libc directory.
6587 * added ADC library under libio. Preliminary version yet.

6597 * (pic16_storeForReturn): optimized return of 0,
6598 * (genCmp): experimental code for new genCmp which uses PIC18's
6599 special compare&skip instructions. Initial tests fail some times
6600 with variables grater than 1 byte in size, so new code is disabled,
6601 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6603 * (genCast): began a fix to optimize the casting of a bit to another
6604 bit, now assigning a bitfield to another bitfield will fail, sorry,
6605 * src/pic16/main.c: disabled the use of lr-support feature,
6606 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

6613 and 1 for banking instruction,
6614 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6615 caused stop processing pCodes after a inline assembly block,
6616 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

6618 registers when it shouldn't,
6619 * src/pic16/ralloc.c (allocReg): add preliminary support for
6620 supporting a limited set of temporary registers,
6622 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9518 * src/SDCCast.c (addCast): added promotion to int
9519 (decorateType): updated call to upCast()
9520 * src/SDCCicode.c (geniCodeLeftShift): removed call to
9521 usualUnaryConversions()
9523 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
9525 * support/regression/tests/literalop.c (mulWrapper): Added a
9526 wrapper to remove integer overflow warnings.
9528 * support/regression/tests/float_trans.c: Made work on host.
9530 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
9533 * support/regression/generate-cases.py (main): Changed from inline
9536 * doc/Makefile (install): Changed to depth first to get rid of
9537 missing directory install warning.
9539 * as/Makefile (install-doc): Made work on Mac.
9541 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
9543 * src/SDCCast.c: added an additional type flow in decorateType() of
9544 opposite direction, see feature request #860006; it's enabled at runtime
9545 by setting the environment variable SDCC_NEWTYPEFLOW
9546 * src/SDCCast.h: changed prototype of decorateType()
9547 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
9548 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
9549 'char' to 'int' can be omitted, if both operands are 'unsigned char';
9550 see feature request #877103
9551 * src/SDCCval.c: updated call of decorateType()
9552 (valBitwise): fixed bug #882876
9553 (valMinus): added promotion
9554 (valLogicAndOr): result is unsigned
9555 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
9556 * src/SDCCsymt.c (computeType),
9557 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
9558 must not cause an unsigned operation
9559 * src/pic/glue (pic14emitRegularMap),

9579 * src/pic/ralloc.h: applied patch from Slade Rich;
9580 added support for multiple code pages and multiple RAM banks on the
9581 PIC 14 port. The ASM files now no longer simply assume all the
9582 code / RAM are in the same page / bank. This means the linker can
9583 safely allocate code/RAM of separate ASM files to different pages/banks.
9584 * doc/sdccman.lyx: added Slade's tips
9585 * src/mcs51/peeph.def: fixed bug #880768

9597 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
9598 strtof is not part of C89 and isn't included with Mac OS X.
9600 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9602 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

9627 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9629 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9630 loaded with the linker search paths (-L arguments) and the libraries
9631 to be linked with the current source (-l arguments). Changes
9632 currently will affect only the pic16 port.
9633 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9634 include path the port specific paths and port specific libraries,
9635 * gplink command now contains the $3 argument,
9636 * src/pic16/device.h,
9637 * src/pic16/device.c,: structure PIC_device is made public and
9638 renamed to PIC16_device, the same for variable Pics which is renamed

9653 Documenting changes from previous commits.
9654 * configure.in (version 1.56),
9655 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9656 when generating output files to configure the pic16 library,
9657 but now I've commented it out, since gputils aren't installed in the
9658 SF compile farm, so library won't compile
9660 * device/lib/Makefile.in (version 1.56): initially I've added in
9661 target 'all' the prerequestive 'model-pic16' so it compiled the
9662 pic16 library, but now I've commented it out for the same reasons
9664 * added targets 'model-pic16' and 'objects-pic16' to compile the
9666 * added target 'port-specific-objects-pic16' to handle the
9667 generated libraries and copy them into the build/ directory
9668 * added target 'clean-intermediate-pic16' to clean intermediate
9669 files into pic16 directory
9670 * in target 'installdirs' added line to create directory pic16 in
9671 the installation path

9674 added lines to copy all header files to installation path,
9675 * in target 'installdirs' added line create directory for pic16
9676 headers in the installation path

9691 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9692 option so that it actually works. Made it specific to the z80, since
9693 the gbz80 doesn't have these kinds of I/O ports.
9695 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9697 * device/include/z180.h,

9719 Mainly changes to support compilation of the device libraries
9720 * src/pic16/device.c: stack is allocated via symbol and not
9721 via literal number. The symbol is placed in the corresponding
9722 position of the data ram
9723 * (pic16_dump_section): relocatable and absolute uninitialized
9724 data are now emitted in sorted order to reduce section naming,
9725 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9726 weren't marked as being in the access bank,
9728 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9730 Added portion of GNU PIC Library under the directory
9731 device/include/pic16 and device/lib/pic16. These files
9732 contain the declarations of SFRs for the PIC18Fxx2 devices.
9733 The directory is initialized via configure from toplevel.

9763 all over. Telling LaTeX to be less strict with word spacing
9764 to better keep the right margin. Changed some notes about
9765 maintainance of the ports in section 3.2.1 - is it OK like this?
9767 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9807 * src/pic16/peeph.def: all peepholes with movff are commented out,
9808 because there is a problem in the pcode peep optimizer,
9809 * src/pic16/ralloc.c: the register allocator can now reuse local

9948 Bug reported from Jesus Calvino-Fraga
9950 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9952 * sdcc.spec: updated
9953 * device/include/Makefile.in: don't install CVS directories
9954 * device/lib/Makefile.in: added removal of CVS directories after install
9955 * doc/Makefile: fixed install, added local_icons
9956 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9957 * src/mcs51/gen.c (genRightShift): fixed bug #870788

9961 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9963 PIC16 port related changes:
9964 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9965 added variable stackPos,
9967 * gen.c: genCall, assignResultValue: added support for
9968 pushing/retrieving function parameters to/from stack,
9969 genFunction,genEndFunction: setup stack frame for the
9971 genAddrOf: will be changed according to bug 863624
9973 * added files genutils.c and genutils.h which contain gen*
9974 debugged and optimised functions extracted from gen.c
9976 * glue.c: added variable 'externs' which holds extern symbols,
9977 pic16emitRegularMap: is modified to properly handle relocatable
9978 symbols under the new scheme,
9979 pic16createInterruptVect: is modified
9980 pic16printPublics: is modified to emit 'global' assembler directives,
9981 added pic16_printExterns to print extern symbols,
9982 pic16glue: initializes stack/frame pointer in the beginning of
9983 the assembly output. Temporary hack, will be corrected later,
9984 because gplink yet does not support stack and SDCC does not
9985 yet support a type of crt0.o object to create the final binary.
9987 * Removed many lines that contain 8051 legacy code.
9988 * The code is finally placed under a 'code' directive.
9989 * Added port specific options.
9991 * _process_pragma: simplified since now we do not need *special*
9992 include file to define SFR registers. But a separate header
9993 will be needed. This will be developed later.
9994 * _pic16_parseOptions: added, parses port specific options:
9995 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9996 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9997 --preplace-udata-with=
9999 * _pic16_setDefaultOptions: modified to initialize section names,
10000 but hack is temporarly out of order since it needs improvement.
10001 * _pic16_genAssemblerPreamble: configuration words are emitted by
10002 their address instead of their name. This part is incomplete and
10003 supports only the 18Fxx2 devices. Other devices will emit an error
10004 during assembly since they do not contain the same set of config
10006 * _pic16_genIVT: is modified,
10008 * pcode.c: added definitions for some hardware registers that are needed
10010 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
10011 All PCI entries are updated. Now LFSR is supported.
10012 * Removed pic16_pciTRIS is mentioned by mdubuc in source
10013 * added pic16_newpCodeOpLit2 to support instructions with
10014 two literal arguments
10015 * pic16_pCode2str: corrected code that emits assembler instructions
10016 with two literal operands and those that have an access bit modifier
10017 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
10018 this fixes a bug which caused some labels to be lost, when an
10019 assembler directive was added, i.e. banksel,
10020 * pic16_FixRegisterBanking: improved logic that causes the insertion
10022 * InlineFunction: functions that are called once, are not any more
10023 inlined. This can be a port option in the future,
10025 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
10027 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
10028 hold the corresponding uninitialized symbols,
10029 * pic16_allocProcessorRegister: registers have explicit marked the
10031 * pic16_allocInternalRegister: registers are explicit marked as
10033 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
10034 processing list, so bit registers were lost,
10037 * ralloc.h: added field 'accessBank' and original symbol operand
10038 in register definition,
10039 * removed the field isMapped from register definition,
10041 ** Several functions have been removed from various sources:
10042 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
10043 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
10044 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
10045 pic16_assignRelocatableRegisters
10047 ** others have been introduced:
10048 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
10049 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
10051 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10053 * support/scripts/inc2h.pl: changed definition of BIT_AT
10054 to emit 'sbit at' instead of 'bit at'. This was a request.
10056 PIC16 port related preliminary changes:
10057 * gen.c: prefixed function popRegFromString with
10058 pic16_ and all references to it corrected
10059 * pcode.c: all pic16_pc_* hardware registers prefixed
10060 with underscore (_),
10061 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10062 * ralloc.c: newReg(): when register is REG_SFR then
10063 set address to rIdx,
10064 pic16_allocProcessorRegister(): marks register wasUsed=0
10065 pic16_writeUsedRegs(): added a call to assign processor
10066 registers via pic16_assignFixedRegisters
10068 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10070 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10071 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10072 variables in unused register banks. Also the SSEG is placed
10073 wherever there is enough space for it, and IDATA can be anywhere
10074 in internal RAM. For now compile using -Wl-Y[stack_size].
10075 The mem file is different for this option as well, since it
10076 makes no sense of talking about DSEG lenght.
10078 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
10080 * src/SDCClrange.c: fixed bug 869095 that caused segfault
10081 in certain cases, e.g. when ROM assignment, patch provided
10082 from Albert den Haan.

10325 * src/SDCCast.c (decorateType): disabled a transformation I added in
10326 revision 1.188 (access to fields of a structure at an absolute address);
10327 it breaks with bitfields, extern declarations, and gcse analysis.
10328 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10329 could be assigned through a pointer, so don't complain.

10952 correct when using both critical and reentrant/stack-auto.
10953 * src/z80/gen.c (aopOp): removed erroneous assertion about sloc
10954 size (can be triggered in error if sloc is shared between
10955 different sized objects)
10956 * device/include/float.h: fixed macros to explicitly use
10957 unsigned long where needed
10959 2003-09-15 Bernhard Held <bernhard AT bernhardheld.de>

10967 * src/SDCCsymt.c (sclsFromPtr),
10969 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10970 support for standard C idiom of memory mapped variables; for
10971 example, *((xdata int*)0x1234) = 1 is now internally equivalent
10972 to xdata int at 0x1234 tempvar = 1.
10973 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch

10990 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10992 Fixed bug #621531 (const & volatile confusion in the type chain).
10993 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10994 refer to the const or volatile state of the pointer itself.

11064 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
11066 * device/lib/_mullong.c: replaced int by short for gcc
11068 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11070 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
11071 and JUMPTABLE iCodes properly now (worked by accident before)
11072 * src/mcs51/gen.c (leftRightUseAcc),
11073 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
11074 iCode properly now. Use getSize instead of nRegs since a & b
11075 aren't part of the nRegs tally.
11077 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
11079 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

11089 copied from genNearPointerSet()
11090 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
11091 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
11092 If they pop r0/r1 they must be called in the opposite order than aopOp().
11093 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
11094 (resp. --stack-auto), prepared for --xstack
11096 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11098 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
11100 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>

11105 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
11107 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11108 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
11109 type for bits was changed. It resulted in bit variables becoming
11110 global, which is not permitted in PIC 14 assembly output.
11112 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11114 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11116 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11118 Z80 and MCS51 linkers complaint if a public symbol is defined
11119 in more than one library module:

11125 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11127 A few small changes that speed up the peephole optimizer.
11131 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11133 Try to make the peephole optimizer smarter by maintaining
11134 an association between the assembly source code and the
11135 iCodes that originated them. Put this information to use
11136 with a new peephole rule condition "notVolatile" so that
11137 the rules can be aggressive yet still safe.
11142 * src/mcs51/peeph.def
11144 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11148 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11149 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11150 if the left or right operand symbols have the accuse flag set.
11152 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11154 Changed the type of the result of the ! (NOT) operator to char;
11155 previously it returned the same type as the source. This allows
11156 us to eliminate all the genFloatNot functions (all of its target
11157 implementations were very buggy) since !float can use the same
11160 * src/SDCCicode.c (ast2iCode): ! returns char
11161 * src/mcs51/gen.c (genNot, genNotFloat),
11162 * src/ds390/gen.c (genNot, genNotFloat),

11169 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11170 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11171 during interrupts. Ensure WSAVE is located at a shared bank address.
11172 2. Fixed page selection in some places
11173 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11174 the registers name strings.
11175 4. Fixed "signed / unsigned compare" compiler warnings.
11176 5. The PIC port manages its own allocation of the general purpose
11177 registers, but makes no attempt to reuse them. As a result when
11178 compiling it soon runs out of general purpose registers. Some
11179 additional code was added to the files pcode.c and device.c to walk
11180 through the function call tree and rename the registers so that they
11190 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11191 genPlus() & genMinus() when the result is the same as left or right
11193 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11197 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11199 Made bitfield a distinct type from bit so that bitfields
11200 convert as per ANSI C and bits retain their traditional
11201 boolean style behaviour. Implemented bitfield support in
11209 * src/ds390/gen.c: bit v bitfield split
11210 * src/z80/gen.c: New support for bitfields
11211 * support/regression/tests/bitfields.c: reenabled z80,
11214 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11216 Rules 246.x, 247.x relate to bitfields, the others speed up
11217 access to xdata mapped I/O devices.
11219 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11221 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11223 Cleaned up genPackBits and genUnpackBits and added two helper
11224 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11225 for literal assignments in genPackBits (thanks to Frieder for
11231 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11233 Fixed bug #748310 (pointer to function type mishandled when the
11234 function name is omitted). Also fixed a SIGSEGV when a function
11235 attribute (reentrant, etc) is used on a non-function or on a
11236 function but misplaced before the parameter list.
11238 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11240 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11241 * support/Util/SDCCerr.h,
11242 * support/Util/SDCCerr.c: Added func attr misuse error msg
11244 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11246 Fixed bug #787649 by anonymous
11247 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11248 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11250 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11252 Fixed numerous bitfield problems.
11254 * src/SDCC.y: More bitfield related error checking

11263 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11265 Made the constant following the "interrupt" keyword optional. If
11266 omitted, the function will not automatically be given an entry
11267 in the interrupt vector table (similar to #pragma NOIV, but
11268 less syntacticly kludgy). The interrupt number is also now
11269 range checked. Also fixed a bug in the high order bit example

11277 * support/Util/SDCCerr.h
11280 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11283 * src/SDCCicode.c (operandOperation): rewritten some ops
11284 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11285 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11287 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11288 be re-activated by defining REDUCE_LITERALS)
11289 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11290 unsigned, but are signed by default
11291 * src/SDCCval.c (constVal): rearranged
11292 * src/SDCCval.c (valMod): preliminary fix
11293 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11331 2003-08-05 Bernhard Held <bernhard AT bernhardheld.de>
11333 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11334 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11335 constants are unsigned; added recognition of "u" flag for unsigned
11336 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11337 * src/SDCCval.c (valDiv, valMod): fixed signdness

11800 messages from optionsTable when a port is not configured, added
11801 support for the PIc16 port in the ports table, when executing
11802 the compiler with no port specified on command line, a default
11803 port is selected with the new macro DEFAULT_PORT which is
11804 defined in port.h, in setDefaultOptions() linkOptions is removed
11805 from initialization assignment, since now it is a set,
11806 parseCmdLine uses setParseWithComma for linkOptions, in
11807 linkEdit() linkOptions are accessed with new function indexSet()
11808 which returns the i'th item of a set variable. See SDCCset.c, in
11809 linkEdit() when calling buildCmdLine(), added linkOptions as
11810 last argument. Now users can pass arguments to gplink via the
11811 -Wl option, main() uses pic16glue() to glue up pic16 programs

11825 gpasm complaining and test the linkage with gplink, _linkCmd and
11826 _asmCmd changed to be more gplink and gpasm friendly
11827 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11828 produced an error when parsed, peep rule 12 is added to utilize
11829 movff, but it is commented out since the pCode does not support
11830 yet a command with 2 address arguments
11832 2003-05-18 <johan AT balder>
11834 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12809 2003-01-12 Bernhard Held <bernhard AT bernhardheld.de>
12811 * src/SDCCmain.c (main): port->finaliseOptions() moved for z80 linking
12812 * src/SDCCutil.c (join): ugly bug: missing '\0'

12854 * src/SDCCast.c (decorateType): fixed bug #600035
12856 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
12857 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
12858 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
12859 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings

12867 2003-01-06 <johan AT balder>
12869 * src/SDCCicode.c: fixed array add
12871 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
12872 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
12873 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
12875 2003-01-04 <johan AT balder>

12879 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12880 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
12882 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12883 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
12884 * support/regression/tests/bug-524697.c: fit mem usage into 8032
12886 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12887 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
12889 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
12890 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12892 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12893 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12895 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12897 * in /sdcc/as/mcs51/ changed these files in order to create an
12898 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12899 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12900 following files to include the previous two files: aslink.dsp,
12901 Makefile.aslink, Makefile.bcc, and Makefile.in.
12903 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12904 .adb instead of .cdb
12906 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12908 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12909 value from option --iram-size.
12911 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12913 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12916 2002-09-18 <wiml AT hhhh.org>
12918 * SDCClrange.h: exposed setFromRange() and setToRange()
12919 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12920 packRegsForAccUse() (bug 542397)
12921 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12922 multiple times and emitting the fetch operations more than once
12923 added aopGetUsesAcc() function to allow binary operators to
12924 fetch their operands in the correct order; made genMinus() emit
12925 compact code for X = LITERAL - Y
12927 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12928 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12929 sprintf() in line 1267.
12931 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12932 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12935 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12936 Changes to aslink (All the changes are marked with 'JCF'):
12938 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12941 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12942 area BSEG. Also moves, if possible, the DATA area down into the internal
12943 ram so more space is available.
12945 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12948 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12949 not bytes. Function summary() which creates a memory usage summary
12950 file with extension .mem. Reports of overlaping stack and small stack
12951 size. If the space for the stack is less than 16 bytes aslink trows a
12954 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12955 the 8051. Option 'y' for memory summary output file.
12957 Changes to sdcc (All the changes are marked with 'JCF'):
12959 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12961 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12962 overlaying area for it (uses RegBankUsed[4]).
12964 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12965 bank zero as used by default. By default aslink locates the stack
12966 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12967 the creation of the .mem file. Delegates the allocation of data area
12968 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12969 the begining of the stack area to aslink.
12971 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12972 glue() in SDCCglue.c creates an area for it.
12974 2002-09-03 Borut Razem <borut.razem AT siol.net>
12975 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12976 sdcc/src/pic/glue.c:
12977 introduced atexit() handler for teporay files removal in case of
12978 errors, assertions, ...
12980 2002-08-29 Borut Razem <borut.razem AT siol.net>
12981 * sdcc/support/cpp2/auto-host_vc_in.h:
12982 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12983 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12984 Maybe there is a similar problem with BORLANDC? It should be checked!
12986 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12987 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12988 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12989 was not executed, and the compiler (cl) launched a warning:
12990 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12992 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12993 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12995 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12996 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12998 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12999 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
13000 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
13001 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13002 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
13003 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
13004 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
13005 - added Release configuration in VS projects
13006 - review of compiler an linker options
13007 - VC .exe files are generated in bin_vc directory, not to interfere
13008 with binaries generated from other projects (cygwin, mingw, bcc ...)
13010 * sdcc/src/yacc.dsp: added
13012 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
13013 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
13014 and insert the version number definitions from .version
13016 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
13018 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
13019 added - genarate auto-host.h using auto-host_vc_in.h as template
13022 removed from CVS, generated automatically
13024 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
13025 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
13027 2002-08-11 Borut Razem <borut.razem AT siol.net>
13028 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
13030 2002-08-10 Borut Razem <borut.razem AT siol.net>
13031 * src/SDCCmain.c (main):
13032 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
13033 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
13034 The consequence was that some temporary files were not removed.
13037 unification of code in functions tempfilename() and tempfile():
13038 function tempnam() is defined in Visual Studio 6.0 and .NET
13040 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
13042 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13043 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
13044 - removed compiler command line option /WX: Treats all warnings as errors
13045 - update a list of source files, included into the project
13047 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13048 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13049 changed project type to Generic Project so that can be correcly converted to VS.NET project
13051 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13053 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13055 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13057 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13058 added return 0 statements after assert() to make compiler happy
13060 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13061 added newline in the def file to keep MSC compiler satisfied
13063 * sdcc/src/z80/gen.c:
13064 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13065 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13066 - solved MSC error in function aopDump()
13068 * sdcc_vc.h: define PREFIX as "\\sdcc"
13070 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13071 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
13073 2002-06-22 Scott Dattalo <scott AT dattalo.com>
13074 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
13075 - Rewrote the register banking algorithm.
13076 - Added pCode live-range analysis to registers (for now, only non-used and
13077 singly-used registers optimized away)
13079 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
13081 * 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.

13096 2002-04-15 Michael Hope <michaelh AT vroom>
13098 * device/lib/z80/printf.c (sprintf): Added.
13100 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
13102 * src/z80/peeph.def: Added transpose redundent load rule.
13104 * src/z80/main.c: Added force callee saves for jaune.
13106 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
13108 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
13110 2002-03-28 Johan Knol <johan AT balder>
13112 * src/SDCCval.c: fixed bug #532436
13114 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13116 Added "char *Processor" field to the port structure.
13119 Added -p option. Allows port dependent processor to be specified.
13122 Initialized the new field char *Processor field to NULL in all ports
13125 Compiler generated registers for interrupt context saving
13126 were not getting allocated.
13128 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13131 Fixed left shift. Will promote the left side of a left shift
13132 if a) left shifting more than size of operand or b) when assigned
13133 to something size > size of left side
13135 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13137 tons of changes. Register allocation has been
13138 rewritten. Added customization for the various PICs. Flow
13139 analysis is restructured. ...
13141 * src/pic/device.h:
13144 * src/pic/device.c:
13145 Added. device.c is a PIC port hack to accomodate variations
13148 2002-03-13 Michael Hope <michaelh AT vroom>
13150 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
13152 2002-03-04 johanknol <johanknol AT manik>
13154 * /src/SDCCval.c: fixed
13156 const unsigned char arr[][2] = { { 0, 1 } };
13157 t18.c:1: error: Initializer element is not constant

13215 * src/z80/ralloc.c (packRegsForIYUse): Fixed fp bug where four byte operands were packed into IY.
13217 2002-03-01 <johan AT FRIJA>
13219 * src/SDCCglue.c (printIvalPtr): fixed bug #524211
13221 * src/SDCCast.c (decorateType): fixed bug #524209

13243 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13245 * sdcc/src/SDCCloop.c:
13246 Previous fix was not good. basic blocks that have "break" or "return" are
13247 not really partof a loop , but live ranges used in these blocks should
13248 be live thru the entire loop, so set partOfLoop but don't add them to
13251 2002-02-21 <johan AT FRIJA>
13253 * src/SDCCcse.c: fixed bug #514308
