458 Enabled VPATH feature: changed nearly all Makefiles (149 files).
459 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
461 One basic decision: e.g. src/clean.mk includes further files. In order
462 to make this work there are two solutions:
463 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
464 run configure on them. This way they can use
465 'include $(srcdir)/port-clean.mk'
466 - always include clean.mk by the Makefile at the same level. To avoid
467 that `make clean` tries to include and build Makefile.dep the
468 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
469 implemented, because now even `make uninstall` doesn't create
470 Makefile.in. clean.mk could be eliminated by pasting it in
473 * debugger/mcs51/Makefile.in: build own objects from library sources
474 (SLIB, SDCC) in current directory
476 * configure, configure.in: renamed --disable-device-lib-build in
477 --disable-device-lib; added --enable-doc, the required tools are

764 and enabled nesting of critical functions though not for gbz80
765 (genCritical, genEndCritical): added functions
766 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
767 * src/z80/mappings.i: added "ei" to all mappings

776 2006-03-16 Raphael Neider <rneider AT web.de>
778 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
779 the left operand is shorter than the result (c* = lit-c* + int),
781 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
784 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
786 * src/.version: increased version number to 2.5.5
787 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
788 linking is done manually in pic16 port's _linkEdit,
789 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
790 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

806 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
807 call to allocReg, not by manually allocating a new one,
808 (pic16_assignRegisters): now before going through the register
809 allocating functions mark all registers as free. This eliminates some
810 side effects resulting from peephole parser done earlier in the backbone
812 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
814 * src/SDCCicode.c (geniCodeLogic),

862 2006-03-06 Borut Razem <borut.razem AT siol.net>
864 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
865 made the linker quiet
867 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
869 * src/pic16/gen.c (genPcall): fixed bug #1443644
870 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
871 which dumps before the function entry point a data byte which represents
872 the number of the local variables used by the specified function, added
873 'xinst' for initial support for Extended Instruction Support,
874 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
875 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
876 port->fun_prefix anymore (may change later),
877 (genFunction, genEndFunction): do not store/restore local registers for
878 _main (this should take care the --main-return command line option in
880 (genOr): removed some legacy pic-port instructions,
881 * src/pic16/genarith.c (genAddLit): re-enabled old code because
882 performing operations with SFR's causes data to be written more than
883 once to each SFR. Perhaps SFRs should be handled in special cases...
884 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
886 * src/pic16/main.c (_process_pragma): stack bound checking did not take
887 into account for stack starting position,
888 (struct OPTIONS pic16_optionsTable): added command line argument
889 --extended or -y for Extended Instruction Support,
890 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
891 (deassignLRs): *** perhaps the most important change, old 'for' code
892 (commented out for reference), didn't account for some registers which
893 were left marked 'not free' after a pointer operation. The change
894 reduces register usage a lot in some cases

3170 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3171 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3172 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3173 always available in leading double underscore form. The C99 support is
3174 mostly missing, but it's a start.
3175 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3176 reserved identifier "__data".

3254 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3256 * device/lib/printf_large.c: removed inline assembly for portability and
3257 readability. Use printf_fast if speed or size are more important.
3258 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3259 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3261 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3263 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3264 prevent compiler warning
3266 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3268 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3269 moved to level 0 and declared as static. Also they are explicit
3270 placed in access bank. This was necessery because some times they
3271 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3272 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3273 optimizations. Currently only compare to unsigned char is implemented,
3274 * src/pic16/gen.c: added fReturnIdx array,
3275 * (struct resolvedIfx) is moved to gen.h and made public,
3276 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3277 * (aopForSym): added an optimization to directly store in stack of
3278 the operand of a SEND iCode,
3279 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3280 but as registers instead (AOP_REG) using the fReturnIdx array,
3281 * (pic16_freeAsmop): remove the freed register from the
3282 _G.sregsAlloc field,
3283 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3284 a compare of 'WREG',
3285 * (pic16_popGetTempRegCond): changed function prototype, now
3286 function takes also a bitVector argument v which holds the current
3287 set of registers that are allocated for stack access by aopForSym,
3288 registers allocated in aopForSym for accessing stack symbols are not
3289 any more part of the functions usedRegs field,
3290 * (genCall): some times aopOp is called for a stack variable to be
3291 send, aopForSym might perform the push, if this is true make sure
3292 that genCall doesn't push the variable twice by testing _G.resDirect,
3293 * (genFunction): changed testing for unspecified interrupt number
3294 from 256 to INTNO_UNSPEC,
3295 * modified selection scheme of frame pointer generation. Previously
3296 if function did use local registers a frame pointer was generated,
3297 now a frame pointer is generated only if function has arguments
3298 (that need PLUSW2 register access), or has stack arguments, or the
3299 compiler is not instructed to omit the frame pointer,
3300 * (genEndFunction): before restoring local registers that were saved
3301 in the function preamble, also restore the registers that *might*
3302 have been allocated for stack access,
3303 * (genRet): removed some old comments,
3304 * (genCmp, the active (RN's) version): added a call to the
3305 pic16_genCmp_special function to perform the compare with a more
3306 robust and optimized way,
3307 * (genInline): a feature has been added in inline code generation,
3308 which allows a wildcard variable substitution when writing inline
3309 assembly. Code is incomplete and experimental therefore undocumented,
3310 * (genCast): changed order of aopOp for result and right to allow
3311 aopForSym to directly load the result if possible,
3312 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3313 perform an optimized compare on some selected special occasions,
3314 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3315 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3316 generate an IVT any more,
3317 * src/pic16/main.c (pic16_optionsTable): added command line option
3319 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3320 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3322 * src/pic16/NOTES: Raphael Neider added in list of active developers
3323 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3324 jumptable_end to prevent bug #,
3325 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3326 inCond and outCond fields,
3327 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3328 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3329 turn off register spilling,
3330 * (packRegsForOneUse): synced with other ports' versions although it
3331 is not used currently,
3332 * (pic16_packRegisters): added an optimization while reading
3333 structure bitfields, some registers may be saved (malloc code is
3334 decreased by 80 bytes)
3336 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3338 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3339 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3340 this can be optimized more?
3342 2005-03-10 Raphael Neider <rneider AT web.de>
3344 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3345 genNearPointerGet): (hopefully) fixed access to bitfields via
3346 pointers (p->bitN = x; and x = p->bitN; failed)
3348 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3350 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3980 Adding support for replacing ljmps with sjmps in jumptables
3981 generated for switch statements. For now you need to set the
3982 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3983 Now 4 algorithms for mcs51 jumptable generation are used:
3984 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3985 addresses loaded pc-relative for up to 112 cases and stack-pushing
3986 target addresses loaded with offset from dptr for up to 256 cases.
3988 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
3989 * src/mcs51/main.c: adapted constants for switch table generation

4013 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4014 to call when a stack overflow occurs,
4015 * (malloc.h): added CVS Id tag,
4016 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4018 * added libc directory. The current version of LibC contains string
4019 functions, ctype functions and macros and some functions of the
4020 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4021 be extensively tested in the future. Standard disclaimer here.
4022 Library is not automatically build yet. But one can build it by
4023 invoking 'make' inside the libc directory.
4024 * added ADC library under libio. Preliminary version yet.

4033 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4034 * (pic16_storeForReturn): optimized return of 0,
4035 * (genCmp): experimental code for new genCmp which uses PIC18's
4036 special compare&skip instructions. Initial tests fail some times
4037 with variables grater than 1 byte in size, so new code is disabled,
4038 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4040 * (genCast): began a fix to optimize the casting of a bit to another
4041 bit, now assigning a bitfield to another bitfield will fail, sorry,
4042 * src/pic16/main.c: disabled the use of lr-support feature,
4043 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4046 bits with offset (case PO_GPR_BIT),
4047 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4049 * (isBankInstruction): modified to return 0 for no banking instruction,
4050 and 1 for banking instruction,
4051 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4052 caused stop processing pCodes after a inline assembly block,
4053 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4054 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4055 registers when it shouldn't,
4056 * src/pic16/ralloc.c (allocReg): add preliminary support for
4057 supporting a limited set of temporary registers,
4059 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4061 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4062 genDataPointerSet): ensure assignments always copy in MSB to LSB
4064 (loadRegFromAop): recognize CLRH optimization,
4065 (genFunction): optimize RECEIVE iCodes in reentrant functions
4067 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4069 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6987 see feature request #877103
6988 * src/SDCCval.c: updated call of decorateType()
6989 (valBitwise): fixed bug #882876
6990 (valMinus): added promotion
6991 (valLogicAndOr): result is unsigned
6992 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
6993 * src/SDCCsymt.c (computeType),
6994 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
6995 must not cause an unsigned operation
6996 * src/pic/glue (pic14emitRegularMap),
6997 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
6999 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
7001 * src/pic/pcode.c (PCodeID): commented out left over debug code
7003 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
7005 * support/valdiag/tests/overflow.c: added shift tests
7013 * src/pic/pcodepeep.c,
7014 * src/pic/pcoderegs.c,
7016 * src/pic/ralloc.h: applied patch from Slade Rich;
7017 added support for multiple code pages and multiple RAM banks on the
7018 PIC 14 port. The ASM files now no longer simply assume all the
7019 code / RAM are in the same page / bank. This means the linker can
7020 safely allocate code/RAM of separate ASM files to different pages/banks.
7021 * doc/sdccman.lyx: added Slade's tips
7022 * src/mcs51/peeph.def: fixed bug #880768

7031 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
7034 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7035 strtof is not part of C89 and isn't included with Mac OS X.
7037 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7039 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7064 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7066 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7067 loaded with the linker search paths (-L arguments) and the libraries
7068 to be linked with the current source (-l arguments). Changes
7069 currently will affect only the pic16 port.
7070 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7071 include path the port specific paths and port specific libraries,
7072 * gplink command now contains the $3 argument,
7073 * src/pic16/device.h,
7074 * src/pic16/device.c,: structure PIC_device is made public and
7075 renamed to PIC16_device, the same for variable Pics which is renamed

7090 Documenting changes from previous commits.
7091 * configure.in (version 1.56),
7092 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7093 when generating output files to configure the pic16 library,
7094 but now I've commented it out, since gputils aren't installed in the
7095 SF compile farm, so library won't compile
7097 * device/lib/Makefile.in (version 1.56): initially I've added in
7098 target 'all' the prerequestive 'model-pic16' so it compiled the
7099 pic16 library, but now I've commented it out for the same reasons
7101 * added targets 'model-pic16' and 'objects-pic16' to compile the
7103 * added target 'port-specific-objects-pic16' to handle the
7104 generated libraries and copy them into the build/ directory
7105 * added target 'clean-intermediate-pic16' to clean intermediate
7106 files into pic16 directory
7107 * in target 'installdirs' added line to create directory pic16 in
7108 the installation path
7110 * device/include/Makefile.in (version 1.11): in target 'install'
7111 added lines to copy all header files to installation path,
7112 * in target 'installdirs' added line create directory for pic16
7113 headers in the installation path

7128 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7129 option so that it actually works. Made it specific to the z80, since
7130 the gbz80 doesn't have these kinds of I/O ports.
7132 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7134 * device/include/z180.h,

7156 Mainly changes to support compilation of the device libraries
7157 * src/pic16/device.c: stack is allocated via symbol and not
7158 via literal number. The symbol is placed in the corresponding
7159 position of the data ram
7160 * (pic16_dump_section): relocatable and absolute uninitialized
7161 data are now emitted in sorted order to reduce section naming,
7162 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7163 weren't marked as being in the access bank,
7165 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7167 Added portion of GNU PIC Library under the directory
7168 device/include/pic16 and device/lib/pic16. These files
7169 contain the declarations of SFRs for the PIC18Fxx2 devices.
7170 The directory is initialized via configure from toplevel.
7172 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7174 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

7200 all over. Telling LaTeX to be less strict with word spacing
7201 to better keep the right margin. Changed some notes about
7202 maintainance of the ports in section 3.2.1 - is it OK like this?
7204 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7242 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7244 * src/pic16/peeph.def: all peepholes with movff are commented out,
7245 because there is a problem in the pcode peep optimizer,
7246 * src/pic16/ralloc.c: the register allocator can now reuse local

7398 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7400 PIC16 port related changes:
7401 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7402 added variable stackPos,
7404 * gen.c: genCall, assignResultValue: added support for
7405 pushing/retrieving function parameters to/from stack,
7406 genFunction,genEndFunction: setup stack frame for the
7408 genAddrOf: will be changed according to bug 863624
7410 * added files genutils.c and genutils.h which contain gen*
7411 debugged and optimised functions extracted from gen.c
7413 * glue.c: added variable 'externs' which holds extern symbols,
7414 pic16emitRegularMap: is modified to properly handle relocatable
7415 symbols under the new scheme,
7416 pic16createInterruptVect: is modified
7417 pic16printPublics: is modified to emit 'global' assembler directives,
7418 added pic16_printExterns to print extern symbols,
7419 pic16glue: initializes stack/frame pointer in the beginning of
7420 the assembly output. Temporary hack, will be corrected later,
7421 because gplink yet does not support stack and SDCC does not
7422 yet support a type of crt0.o object to create the final binary.
7424 * Removed many lines that contain 8051 legacy code.
7425 * The code is finally placed under a 'code' directive.
7426 * Added port specific options.
7428 * _process_pragma: simplified since now we do not need *special*
7429 include file to define SFR registers. But a separate header
7430 will be needed. This will be developed later.
7431 * _pic16_parseOptions: added, parses port specific options:
7432 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7433 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7434 --preplace-udata-with=
7436 * _pic16_setDefaultOptions: modified to initialize section names,
7437 but hack is temporarly out of order since it needs improvement.
7438 * _pic16_genAssemblerPreamble: configuration words are emitted by
7439 their address instead of their name. This part is incomplete and
7440 supports only the 18Fxx2 devices. Other devices will emit an error
7441 during assembly since they do not contain the same set of config
7443 * _pic16_genIVT: is modified,
7445 * pcode.c: added definitions for some hardware registers that are needed
7447 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7448 All PCI entries are updated. Now LFSR is supported.
7449 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7450 * added pic16_newpCodeOpLit2 to support instructions with
7451 two literal arguments
7452 * pic16_pCode2str: corrected code that emits assembler instructions
7453 with two literal operands and those that have an access bit modifier
7454 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7455 this fixes a bug which caused some labels to be lost, when an
7456 assembler directive was added, i.e. banksel,
7457 * pic16_FixRegisterBanking: improved logic that causes the insertion
7459 * InlineFunction: functions that are called once, are not any more
7460 inlined. This can be a port option in the future,
7462 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7464 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7465 hold the corresponding uninitialized symbols,
7466 * pic16_allocProcessorRegister: registers have explicit marked the
7468 * pic16_allocInternalRegister: registers are explicit marked as
7470 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7471 processing list, so bit registers were lost,
7474 * ralloc.h: added field 'accessBank' and original symbol operand
7475 in register definition,
7476 * removed the field isMapped from register definition,
7478 ** Several functions have been removed from various sources:
7479 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7480 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7481 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7482 pic16_assignRelocatableRegisters
7484 ** others have been introduced:
7485 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7486 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7488 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7490 * support/scripts/inc2h.pl: changed definition of BIT_AT
7491 to emit 'sbit at' instead of 'bit at'. This was a request.
7493 PIC16 port related preliminary changes:
7494 * gen.c: prefixed function popRegFromString with
7495 pic16_ and all references to it corrected
7496 * pcode.c: all pic16_pc_* hardware registers prefixed
7497 with underscore (_),
7498 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7499 * ralloc.c: newReg(): when register is REG_SFR then
7500 set address to rIdx,
7501 pic16_allocProcessorRegister(): marks register wasUsed=0
7502 pic16_writeUsedRegs(): added a call to assign processor
7503 registers via pic16_assignFixedRegisters
7505 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7507 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7508 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7509 variables in unused register banks. Also the SSEG is placed
7510 wherever there is enough space for it, and IDATA can be anywhere
7511 in internal RAM. For now compile using -Wl-Y[stack_size].
7512 The mem file is different for this option as well, since it
7513 makes no sense of talking about DSEG lenght.
7515 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7517 * src/SDCClrange.c: fixed bug 869095 that caused segfault

7764 it breaks with bitfields, extern declarations, and gcse analysis.

8508 and JUMPTABLE iCodes properly now (worked by accident before)
8509 * src/mcs51/gen.c (leftRightUseAcc),
8510 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
8511 iCode properly now. Use getSize instead of nRegs since a & b
8512 aren't part of the nRegs tally.
8514 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
8516 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

8522 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8523 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8524 fetching of the pointer
8525 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8526 copied from genNearPointerSet()
8527 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8528 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8529 If they pop r0/r1 they must be called in the opposite order than aopOp().
8530 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8531 (resp. --stack-auto), prepared for --xstack

8542 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8544 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8545 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8546 type for bits was changed. It resulted in bit variables becoming
8547 global, which is not permitted in PIC 14 assembly output.
8549 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8551 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8564 A few small changes that speed up the peephole optimizer.
8568 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8570 Try to make the peephole optimizer smarter by maintaining
8571 an association between the assembly source code and the
8572 iCodes that originated them. Put this information to use
8573 with a new peephole rule condition "notVolatile" so that
8574 the rules can be aggressive yet still safe.
8579 * src/mcs51/peeph.def
8581 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8585 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8586 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8587 if the left or right operand symbols have the accuse flag set.
8589 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8591 Changed the type of the result of the ! (NOT) operator to char;
8592 previously it returned the same type as the source. This allows
8593 us to eliminate all the genFloatNot functions (all of its target
8594 implementations were very buggy) since !float can use the same
8597 * src/SDCCicode.c (ast2iCode): ! returns char
8598 * src/mcs51/gen.c (genNot, genNotFloat),
8599 * src/ds390/gen.c (genNot, genNotFloat),
8600 * src/z80/gen.c (genNot, genNotFloat),
8601 * src/pic/gen.c (genNot, genNotFloat),
8602 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
8604 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8606 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8607 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8608 during interrupts. Ensure WSAVE is located at a shared bank address.
8609 2. Fixed page selection in some places
8610 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8611 the registers name strings.
8612 4. Fixed "signed / unsigned compare" compiler warnings.
8613 5. The PIC port manages its own allocation of the general purpose
8614 registers, but makes no attempt to reuse them. As a result when
8615 compiling it soon runs out of general purpose registers. Some
8616 additional code was added to the files pcode.c and device.c to walk
8617 through the function call tree and rename the registers so that they
8627 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8628 genPlus() & genMinus() when the result is the same as left or right

8634 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8636 Made bitfield a distinct type from bit so that bitfields
8637 convert as per ANSI C and bits retain their traditional
8638 boolean style behaviour. Implemented bitfield support in
8646 * src/ds390/gen.c: bit v bitfield split
8647 * src/z80/gen.c: New support for bitfields
8648 * support/regression/tests/bitfields.c: reenabled z80,
8651 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8653 Rules 246.x, 247.x relate to bitfields, the others speed up
8654 access to xdata mapped I/O devices.
8656 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8658 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8660 Cleaned up genPackBits and genUnpackBits and added two helper
8661 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8662 for literal assignments in genPackBits (thanks to Frieder for
8668 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8670 Fixed bug #748310 (pointer to function type mishandled when the
8671 function name is omitted). Also fixed a SIGSEGV when a function
8672 attribute (reentrant, etc) is used on a non-function or on a
8673 function but misplaced before the parameter list.
8675 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8677 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8700 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8702 Made the constant following the "interrupt" keyword optional. If
8703 omitted, the function will not automatically be given an entry
8704 in the interrupt vector table (similar to #pragma NOIV, but
8705 less syntacticly kludgy). The interrupt number is also now
8706 range checked. Also fixed a bug in the high order bit example

8720 * src/SDCCicode.c (operandOperation): rewritten some ops
8721 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8722 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8724 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8725 be re-activated by defining REDUCE_LITERALS)
8726 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8727 unsigned, but are signed by default
8728 * src/SDCCval.c (constVal): rearranged
8729 * src/SDCCval.c (valMod): preliminary fix
8730 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8773 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8774 * src/SDCCval.c (valDiv, valMod): fixed signdness
8775 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8776 signedness of modulo, left and right shift

9182 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9183 the regression tests I'm not brave enough to enable 245.b, 245.c
9184 * doc/sdccman.lyx: added latex preamble for hyperref package.
9185 Using pdflatex this will give you a hyperlinked pdf file with
9186 bookmarks. (prepend '%' before /usepackage if this breaks something)

9224 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9226 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9227 it can be defined with CFLAGS when running configure
9228 * src/SDCCmain.c: fixed compiling + linking with object files
9230 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9232 * configure.in: configure for pic16 port,
9233 added --disable-pic16-port
9234 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9235 * src/SDCCmain.c: linkOptions is changed to set *,
9236 added if/endif conditional macros to remove options help
9237 messages from optionsTable when a port is not configured, added
9238 support for the PIc16 port in the ports table, when executing
9239 the compiler with no port specified on command line, a default
9240 port is selected with the new macro DEFAULT_PORT which is
9241 defined in port.h, in setDefaultOptions() linkOptions is removed
9242 from initialization assignment, since now it is a set,
9243 parseCmdLine uses setParseWithComma for linkOptions, in
9244 linkEdit() linkOptions are accessed with new function indexSet()
9245 which returns the i'th item of a set variable. See SDCCset.c, in
9246 linkEdit() when calling buildCmdLine(), added linkOptions as
9247 last argument. Now users can pass arguments to gplink via the
9248 -Wl option, main() uses pic16glue() to glue up pic16 programs

9260 * src/pic16/glue.c: commented out some error producing lines
9261 * src/pic16/main.c: __config directives are commented out to stop
9262 gpasm complaining and test the linkage with gplink, _linkCmd and
9263 _asmCmd changed to be more gplink and gpasm friendly
9264 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9265 produced an error when parsed, peep rule 12 is added to utilize
9266 movff, but it is commented out since the pCode does not support
9267 yet a command with 2 address arguments
9269 2003-05-18 <johan AT balder>
9271 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9272 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9298 2003-05-11 Borut Razem <borut.razem AT siol.net>
9300 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9301 the path of bin directory, so that PATH is the only env. variable, which has to be set
9302 in case of standard installation.
9303 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10380 ram so more space is available.
10382 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10385 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10386 not bytes. Function summary() which creates a memory usage summary
10387 file with extension .mem. Reports of overlaping stack and small stack
10388 size. If the space for the stack is less than 16 bytes aslink trows a
10391 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10392 the 8051. Option 'y' for memory summary output file.
10394 Changes to sdcc (All the changes are marked with 'JCF'):
10396 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10398 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10399 overlaying area for it (uses RegBankUsed[4]).
10401 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10402 bank zero as used by default. By default aslink locates the stack
10403 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10404 the creation of the .mem file. Delegates the allocation of data area
10405 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10406 the begining of the stack area to aslink.
10408 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10409 glue() in SDCCglue.c creates an area for it.
10411 2002-09-03 Borut Razem <borut.razem AT siol.net>
10412 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10413 sdcc/src/pic/glue.c:
10414 introduced atexit() handler for teporay files removal in case of
10415 errors, assertions, ...
10417 2002-08-29 Borut Razem <borut.razem AT siol.net>
10418 * sdcc/support/cpp2/auto-host_vc_in.h:
10419 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10420 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10421 Maybe there is a similar problem with BORLANDC? It should be checked!
10423 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10424 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10425 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10426 was not executed, and the compiler (cl) launched a warning:
10427 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10429 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10430 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10432 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10433 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10435 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10436 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10437 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10438 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10439 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10440 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10441 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10442 - added Release configuration in VS projects
10443 - review of compiler an linker options
10444 - VC .exe files are generated in bin_vc directory, not to interfere
10445 with binaries generated from other projects (cygwin, mingw, bcc ...)
10447 * sdcc/src/yacc.dsp: added
10449 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10450 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10451 and insert the version number definitions from .version
10453 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10455 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10456 added - genarate auto-host.h using auto-host_vc_in.h as template
10459 removed from CVS, generated automatically
10461 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10462 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10464 2002-08-11 Borut Razem <borut.razem AT siol.net>
10465 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10467 2002-08-10 Borut Razem <borut.razem AT siol.net>
10468 * src/SDCCmain.c (main):
10469 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10470 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10471 The consequence was that some temporary files were not removed.
10474 unification of code in functions tempfilename() and tempfile():
10475 function tempnam() is defined in Visual Studio 6.0 and .NET
10477 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10479 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10480 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10481 - removed compiler command line option /WX: Treats all warnings as errors
10482 - update a list of source files, included into the project
10484 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10485 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10486 changed project type to Generic Project so that can be correcly converted to VS.NET project
10488 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10490 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10492 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10494 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10495 added return 0 statements after assert() to make compiler happy
10497 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10498 added newline in the def file to keep MSC compiler satisfied
10500 * sdcc/src/z80/gen.c:
10501 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10502 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10503 - solved MSC error in function aopDump()
10505 * sdcc_vc.h: define PREFIX as "\\sdcc"
10507 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10508 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10556 Added -p option. Allows port dependent processor to be specified.
10559 Initialized the new field char *Processor field to NULL in all ports
10562 Compiler generated registers for interrupt context saving
10563 were not getting allocated.
10565 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10568 Fixed left shift. Will promote the left side of a left shift
10569 if a) left shifting more than size of operand or b) when assigned

10680 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10682 * sdcc/src/SDCCloop.c:
10683 Previous fix was not good. basic blocks that have "break" or "return" are
10684 not really partof a loop , but live ranges used in these blocks should
10685 be live thru the entire loop, so set partOfLoop but don't add them to
10688 2002-02-21 <johan AT FRIJA>
10690 * src/SDCCcse.c: fixed bug #514308
10692 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
