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

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

775 2006-03-16 Raphael Neider <rneider AT web.de>
777 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
778 the left operand is shorter than the result (c* = lit-c* + int),
780 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
783 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
785 * src/.version: increased version number to 2.5.5
786 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
787 linking is done manually in pic16 port's _linkEdit,
788 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
789 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

805 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
806 call to allocReg, not by manually allocating a new one,
807 (pic16_assignRegisters): now before going through the register
808 allocating functions mark all registers as free. This eliminates some
809 side effects resulting from peephole parser done earlier in the backbone
811 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
813 * src/SDCCicode.c (geniCodeLogic),

861 2006-03-06 Borut Razem <borut.razem AT siol.net>
863 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
864 made the linker quiet
866 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
868 * src/pic16/gen.c (genPcall): fixed bug #1443644
869 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
870 which dumps before the function entry point a data byte which represents
871 the number of the local variables used by the specified function, added
872 'xinst' for initial support for Extended Instruction Support,
873 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
874 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
875 port->fun_prefix anymore (may change later),
876 (genFunction, genEndFunction): do not store/restore local registers for
877 _main (this should take care the --main-return command line option in
879 (genOr): removed some legacy pic-port instructions,
880 * src/pic16/genarith.c (genAddLit): re-enabled old code because
881 performing operations with SFR's causes data to be written more than
882 once to each SFR. Perhaps SFRs should be handled in special cases...
883 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
885 * src/pic16/main.c (_process_pragma): stack bound checking did not take
886 into account for stack starting position,
887 (struct OPTIONS pic16_optionsTable): added command line argument
888 --extended or -y for Extended Instruction Support,
889 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
890 (deassignLRs): *** perhaps the most important change, old 'for' code
891 (commented out for reference), didn't account for some registers which
892 were left marked 'not free' after a pointer operation. The change
893 reduces register usage a lot in some cases

3169 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3170 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3171 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3172 always available in leading double underscore form. The C99 support is
3173 mostly missing, but it's a start.
3174 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3175 reserved identifier "__data".

3253 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3255 * device/lib/printf_large.c: removed inline assembly for portability and
3256 readability. Use printf_fast if speed or size are more important.
3257 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3258 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3260 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3262 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3263 prevent compiler warning
3265 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3267 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3268 moved to level 0 and declared as static. Also they are explicit
3269 placed in access bank. This was necessery because some times they
3270 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3271 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3272 optimizations. Currently only compare to unsigned char is implemented,
3273 * src/pic16/gen.c: added fReturnIdx array,
3274 * (struct resolvedIfx) is moved to gen.h and made public,
3275 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3276 * (aopForSym): added an optimization to directly store in stack of
3277 the operand of a SEND iCode,
3278 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3279 but as registers instead (AOP_REG) using the fReturnIdx array,
3280 * (pic16_freeAsmop): remove the freed register from the
3281 _G.sregsAlloc field,
3282 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3283 a compare of 'WREG',
3284 * (pic16_popGetTempRegCond): changed function prototype, now
3285 function takes also a bitVector argument v which holds the current
3286 set of registers that are allocated for stack access by aopForSym,
3287 registers allocated in aopForSym for accessing stack symbols are not
3288 any more part of the functions usedRegs field,
3289 * (genCall): some times aopOp is called for a stack variable to be
3290 send, aopForSym might perform the push, if this is true make sure
3291 that genCall doesn't push the variable twice by testing _G.resDirect,
3292 * (genFunction): changed testing for unspecified interrupt number
3293 from 256 to INTNO_UNSPEC,
3294 * modified selection scheme of frame pointer generation. Previously
3295 if function did use local registers a frame pointer was generated,
3296 now a frame pointer is generated only if function has arguments
3297 (that need PLUSW2 register access), or has stack arguments, or the
3298 compiler is not instructed to omit the frame pointer,
3299 * (genEndFunction): before restoring local registers that were saved
3300 in the function preamble, also restore the registers that *might*
3301 have been allocated for stack access,
3302 * (genRet): removed some old comments,
3303 * (genCmp, the active (RN's) version): added a call to the
3304 pic16_genCmp_special function to perform the compare with a more
3305 robust and optimized way,
3306 * (genInline): a feature has been added in inline code generation,
3307 which allows a wildcard variable substitution when writing inline
3308 assembly. Code is incomplete and experimental therefore undocumented,
3309 * (genCast): changed order of aopOp for result and right to allow
3310 aopForSym to directly load the result if possible,
3311 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3312 perform an optimized compare on some selected special occasions,
3313 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3314 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3315 generate an IVT any more,
3316 * src/pic16/main.c (pic16_optionsTable): added command line option
3318 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3319 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3321 * src/pic16/NOTES: Raphael Neider added in list of active developers
3322 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3323 jumptable_end to prevent bug #,
3324 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3325 inCond and outCond fields,
3326 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3327 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3328 turn off register spilling,
3329 * (packRegsForOneUse): synced with other ports' versions although it
3330 is not used currently,
3331 * (pic16_packRegisters): added an optimization while reading
3332 structure bitfields, some registers may be saved (malloc code is
3333 decreased by 80 bytes)
3335 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3337 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3338 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3339 this can be optimized more?
3341 2005-03-10 Raphael Neider <rneider AT web.de>
3343 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3344 genNearPointerGet): (hopefully) fixed access to bitfields via
3345 pointers (p->bitN = x; and x = p->bitN; failed)
3347 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3349 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3979 Adding support for replacing ljmps with sjmps in jumptables
3980 generated for switch statements. For now you need to set the
3981 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3982 Now 4 algorithms for mcs51 jumptable generation are used:
3983 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3984 addresses loaded pc-relative for up to 112 cases and stack-pushing
3985 target addresses loaded with offset from dptr for up to 256 cases.

4012 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4013 to call when a stack overflow occurs,
4014 * (malloc.h): added CVS Id tag,
4015 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4017 * added libc directory. The current version of LibC contains string
4018 functions, ctype functions and macros and some functions of the
4019 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4020 be extensively tested in the future. Standard disclaimer here.
4021 Library is not automatically build yet. But one can build it by
4022 invoking 'make' inside the libc directory.
4023 * added ADC library under libio. Preliminary version yet.

4032 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4033 * (pic16_storeForReturn): optimized return of 0,
4034 * (genCmp): experimental code for new genCmp which uses PIC18's
4035 special compare&skip instructions. Initial tests fail some times
4036 with variables grater than 1 byte in size, so new code is disabled,
4037 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4039 * (genCast): began a fix to optimize the casting of a bit to another
4040 bit, now assigning a bitfield to another bitfield will fail, sorry,
4041 * src/pic16/main.c: disabled the use of lr-support feature,
4042 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4045 bits with offset (case PO_GPR_BIT),
4046 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4048 * (isBankInstruction): modified to return 0 for no banking instruction,
4049 and 1 for banking instruction,
4050 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4051 caused stop processing pCodes after a inline assembly block,
4052 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4053 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4054 registers when it shouldn't,
4055 * src/pic16/ralloc.c (allocReg): add preliminary support for
4056 supporting a limited set of temporary registers,
4058 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4060 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4061 genDataPointerSet): ensure assignments always copy in MSB to LSB
4063 (loadRegFromAop): recognize CLRH optimization,
4064 (genFunction): optimize RECEIVE iCodes in reentrant functions
4066 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4068 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6986 see feature request #877103
6987 * src/SDCCval.c: updated call of decorateType()
6988 (valBitwise): fixed bug #882876
6989 (valMinus): added promotion
6990 (valLogicAndOr): result is unsigned
6991 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
6992 * src/SDCCsymt.c (computeType),
6993 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
6994 must not cause an unsigned operation
6995 * src/pic/glue (pic14emitRegularMap),
6996 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
6998 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
7000 * src/pic/pcode.c (PCodeID): commented out left over debug code
7002 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
7004 * support/valdiag/tests/overflow.c: added shift tests
7012 * src/pic/pcodepeep.c,
7013 * src/pic/pcoderegs.c,
7015 * src/pic/ralloc.h: applied patch from Slade Rich;
7016 added support for multiple code pages and multiple RAM banks on the
7017 PIC 14 port. The ASM files now no longer simply assume all the
7018 code / RAM are in the same page / bank. This means the linker can
7019 safely allocate code/RAM of separate ASM files to different pages/banks.
7020 * doc/sdccman.lyx: added Slade's tips
7021 * src/mcs51/peeph.def: fixed bug #880768

7030 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
7033 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7034 strtof is not part of C89 and isn't included with Mac OS X.
7036 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7038 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7063 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7065 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7066 loaded with the linker search paths (-L arguments) and the libraries
7067 to be linked with the current source (-l arguments). Changes
7068 currently will affect only the pic16 port.
7069 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7070 include path the port specific paths and port specific libraries,
7071 * gplink command now contains the $3 argument,
7072 * src/pic16/device.h,
7073 * src/pic16/device.c,: structure PIC_device is made public and
7074 renamed to PIC16_device, the same for variable Pics which is renamed

7089 Documenting changes from previous commits.
7090 * configure.in (version 1.56),
7091 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7092 when generating output files to configure the pic16 library,
7093 but now I've commented it out, since gputils aren't installed in the
7094 SF compile farm, so library won't compile
7096 * device/lib/Makefile.in (version 1.56): initially I've added in
7097 target 'all' the prerequestive 'model-pic16' so it compiled the
7098 pic16 library, but now I've commented it out for the same reasons
7100 * added targets 'model-pic16' and 'objects-pic16' to compile the
7102 * added target 'port-specific-objects-pic16' to handle the
7103 generated libraries and copy them into the build/ directory
7104 * added target 'clean-intermediate-pic16' to clean intermediate
7105 files into pic16 directory
7106 * in target 'installdirs' added line to create directory pic16 in
7107 the installation path
7109 * device/include/Makefile.in (version 1.11): in target 'install'
7110 added lines to copy all header files to installation path,
7111 * in target 'installdirs' added line create directory for pic16
7112 headers in the installation path

7127 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7128 option so that it actually works. Made it specific to the z80, since
7129 the gbz80 doesn't have these kinds of I/O ports.
7131 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7133 * device/include/z180.h,

7155 Mainly changes to support compilation of the device libraries
7156 * src/pic16/device.c: stack is allocated via symbol and not
7157 via literal number. The symbol is placed in the corresponding
7158 position of the data ram
7159 * (pic16_dump_section): relocatable and absolute uninitialized
7160 data are now emitted in sorted order to reduce section naming,
7161 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7162 weren't marked as being in the access bank,
7164 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7166 Added portion of GNU PIC Library under the directory
7167 device/include/pic16 and device/lib/pic16. These files
7168 contain the declarations of SFRs for the PIC18Fxx2 devices.
7169 The directory is initialized via configure from toplevel.
7171 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7173 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

7199 all over. Telling LaTeX to be less strict with word spacing
7200 to better keep the right margin. Changed some notes about
7201 maintainance of the ports in section 3.2.1 - is it OK like this?
7203 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7241 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7243 * src/pic16/peeph.def: all peepholes with movff are commented out,
7244 because there is a problem in the pcode peep optimizer,
7245 * src/pic16/ralloc.c: the register allocator can now reuse local

7397 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7399 PIC16 port related changes:
7400 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7401 added variable stackPos,
7403 * gen.c: genCall, assignResultValue: added support for
7404 pushing/retrieving function parameters to/from stack,
7405 genFunction,genEndFunction: setup stack frame for the
7407 genAddrOf: will be changed according to bug 863624
7409 * added files genutils.c and genutils.h which contain gen*
7410 debugged and optimised functions extracted from gen.c
7412 * glue.c: added variable 'externs' which holds extern symbols,
7413 pic16emitRegularMap: is modified to properly handle relocatable
7414 symbols under the new scheme,
7415 pic16createInterruptVect: is modified
7416 pic16printPublics: is modified to emit 'global' assembler directives,
7417 added pic16_printExterns to print extern symbols,
7418 pic16glue: initializes stack/frame pointer in the beginning of
7419 the assembly output. Temporary hack, will be corrected later,
7420 because gplink yet does not support stack and SDCC does not
7421 yet support a type of crt0.o object to create the final binary.
7423 * Removed many lines that contain 8051 legacy code.
7424 * The code is finally placed under a 'code' directive.
7425 * Added port specific options.
7427 * _process_pragma: simplified since now we do not need *special*
7428 include file to define SFR registers. But a separate header
7429 will be needed. This will be developed later.
7430 * _pic16_parseOptions: added, parses port specific options:
7431 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7432 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7433 --preplace-udata-with=
7435 * _pic16_setDefaultOptions: modified to initialize section names,
7436 but hack is temporarly out of order since it needs improvement.
7437 * _pic16_genAssemblerPreamble: configuration words are emitted by
7438 their address instead of their name. This part is incomplete and
7439 supports only the 18Fxx2 devices. Other devices will emit an error
7440 during assembly since they do not contain the same set of config
7442 * _pic16_genIVT: is modified,
7444 * pcode.c: added definitions for some hardware registers that are needed
7446 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7447 All PCI entries are updated. Now LFSR is supported.
7448 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7449 * added pic16_newpCodeOpLit2 to support instructions with
7450 two literal arguments
7451 * pic16_pCode2str: corrected code that emits assembler instructions
7452 with two literal operands and those that have an access bit modifier
7453 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7454 this fixes a bug which caused some labels to be lost, when an
7455 assembler directive was added, i.e. banksel,
7456 * pic16_FixRegisterBanking: improved logic that causes the insertion
7458 * InlineFunction: functions that are called once, are not any more
7459 inlined. This can be a port option in the future,
7461 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7463 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7464 hold the corresponding uninitialized symbols,
7465 * pic16_allocProcessorRegister: registers have explicit marked the
7467 * pic16_allocInternalRegister: registers are explicit marked as
7469 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7470 processing list, so bit registers were lost,
7473 * ralloc.h: added field 'accessBank' and original symbol operand
7474 in register definition,
7475 * removed the field isMapped from register definition,
7477 ** Several functions have been removed from various sources:
7478 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7479 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7480 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7481 pic16_assignRelocatableRegisters
7483 ** others have been introduced:
7484 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7485 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7487 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7489 * support/scripts/inc2h.pl: changed definition of BIT_AT
7490 to emit 'sbit at' instead of 'bit at'. This was a request.
7492 PIC16 port related preliminary changes:
7493 * gen.c: prefixed function popRegFromString with
7494 pic16_ and all references to it corrected
7495 * pcode.c: all pic16_pc_* hardware registers prefixed
7496 with underscore (_),
7497 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7498 * ralloc.c: newReg(): when register is REG_SFR then
7499 set address to rIdx,
7500 pic16_allocProcessorRegister(): marks register wasUsed=0
7501 pic16_writeUsedRegs(): added a call to assign processor
7502 registers via pic16_assignFixedRegisters
7504 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7506 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7507 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7508 variables in unused register banks. Also the SSEG is placed
7509 wherever there is enough space for it, and IDATA can be anywhere
7510 in internal RAM. For now compile using -Wl-Y[stack_size].
7511 The mem file is different for this option as well, since it
7512 makes no sense of talking about DSEG lenght.
7514 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7516 * src/SDCClrange.c: fixed bug 869095 that caused segfault

7763 it breaks with bitfields, extern declarations, and gcse analysis.
7764 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7765 could be assigned through a pointer, so don't complain.

8507 and JUMPTABLE iCodes properly now (worked by accident before)
8508 * src/mcs51/gen.c (leftRightUseAcc),
8509 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
8510 iCode properly now. Use getSize instead of nRegs since a & b
8511 aren't part of the nRegs tally.
8513 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
8515 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

8521 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8522 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8523 fetching of the pointer
8524 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8525 copied from genNearPointerSet()
8526 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8527 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8528 If they pop r0/r1 they must be called in the opposite order than aopOp().
8529 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8530 (resp. --stack-auto), prepared for --xstack

8541 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8543 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8544 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8545 type for bits was changed. It resulted in bit variables becoming
8546 global, which is not permitted in PIC 14 assembly output.
8548 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8550 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8563 A few small changes that speed up the peephole optimizer.
8567 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8569 Try to make the peephole optimizer smarter by maintaining
8570 an association between the assembly source code and the
8571 iCodes that originated them. Put this information to use
8572 with a new peephole rule condition "notVolatile" so that
8573 the rules can be aggressive yet still safe.
8578 * src/mcs51/peeph.def
8580 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8584 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8585 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8586 if the left or right operand symbols have the accuse flag set.
8588 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8590 Changed the type of the result of the ! (NOT) operator to char;
8591 previously it returned the same type as the source. This allows
8592 us to eliminate all the genFloatNot functions (all of its target
8593 implementations were very buggy) since !float can use the same
8596 * src/SDCCicode.c (ast2iCode): ! returns char
8597 * src/mcs51/gen.c (genNot, genNotFloat),
8598 * src/ds390/gen.c (genNot, genNotFloat),
8599 * src/z80/gen.c (genNot, genNotFloat),
8600 * src/pic/gen.c (genNot, genNotFloat),
8601 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
8603 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8605 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8606 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8607 during interrupts. Ensure WSAVE is located at a shared bank address.
8608 2. Fixed page selection in some places
8609 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8610 the registers name strings.
8611 4. Fixed "signed / unsigned compare" compiler warnings.
8612 5. The PIC port manages its own allocation of the general purpose
8613 registers, but makes no attempt to reuse them. As a result when
8614 compiling it soon runs out of general purpose registers. Some
8615 additional code was added to the files pcode.c and device.c to walk
8616 through the function call tree and rename the registers so that they
8626 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8627 genPlus() & genMinus() when the result is the same as left or right

8633 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8635 Made bitfield a distinct type from bit so that bitfields
8636 convert as per ANSI C and bits retain their traditional
8637 boolean style behaviour. Implemented bitfield support in
8645 * src/ds390/gen.c: bit v bitfield split
8646 * src/z80/gen.c: New support for bitfields
8647 * support/regression/tests/bitfields.c: reenabled z80,
8650 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8652 Rules 246.x, 247.x relate to bitfields, the others speed up
8653 access to xdata mapped I/O devices.
8655 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8657 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8659 Cleaned up genPackBits and genUnpackBits and added two helper
8660 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8661 for literal assignments in genPackBits (thanks to Frieder for
8667 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8669 Fixed bug #748310 (pointer to function type mishandled when the
8670 function name is omitted). Also fixed a SIGSEGV when a function
8671 attribute (reentrant, etc) is used on a non-function or on a
8672 function but misplaced before the parameter list.
8674 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8676 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8699 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8701 Made the constant following the "interrupt" keyword optional. If
8702 omitted, the function will not automatically be given an entry
8703 in the interrupt vector table (similar to #pragma NOIV, but
8704 less syntacticly kludgy). The interrupt number is also now
8705 range checked. Also fixed a bug in the high order bit example

8719 * src/SDCCicode.c (operandOperation): rewritten some ops
8720 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8721 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8723 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8724 be re-activated by defining REDUCE_LITERALS)
8725 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8726 unsigned, but are signed by default
8727 * src/SDCCval.c (constVal): rearranged
8728 * src/SDCCval.c (valMod): preliminary fix
8729 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8772 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8773 * src/SDCCval.c (valDiv, valMod): fixed signdness
8774 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8775 signedness of modulo, left and right shift

9181 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9182 the regression tests I'm not brave enough to enable 245.b, 245.c
9183 * doc/sdccman.lyx: added latex preamble for hyperref package.
9184 Using pdflatex this will give you a hyperlinked pdf file with
9185 bookmarks. (prepend '%' before /usepackage if this breaks something)

9223 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9225 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9226 it can be defined with CFLAGS when running configure
9227 * src/SDCCmain.c: fixed compiling + linking with object files
9229 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9232 added --disable-pic16-port
9233 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9234 * src/SDCCmain.c: linkOptions is changed to set *,
9235 added if/endif conditional macros to remove options help
9236 messages from optionsTable when a port is not configured, added
9237 support for the PIc16 port in the ports table, when executing
9238 the compiler with no port specified on command line, a default
9239 port is selected with the new macro DEFAULT_PORT which is
9240 defined in port.h, in setDefaultOptions() linkOptions is removed
9241 from initialization assignment, since now it is a set,
9242 parseCmdLine uses setParseWithComma for linkOptions, in
9243 linkEdit() linkOptions are accessed with new function indexSet()
9244 which returns the i'th item of a set variable. See SDCCset.c, in
9245 linkEdit() when calling buildCmdLine(), added linkOptions as
9246 last argument. Now users can pass arguments to gplink via the
9247 -Wl option, main() uses pic16glue() to glue up pic16 programs

9259 * src/pic16/glue.c: commented out some error producing lines
9260 * src/pic16/main.c: __config directives are commented out to stop
9261 gpasm complaining and test the linkage with gplink, _linkCmd and
9262 _asmCmd changed to be more gplink and gpasm friendly
9263 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9264 produced an error when parsed, peep rule 12 is added to utilize
9265 movff, but it is commented out since the pCode does not support
9266 yet a command with 2 address arguments
9268 2003-05-18 <johan AT balder>
9270 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9297 2003-05-11 Borut Razem <borut.razem AT siol.net>
9299 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9300 the path of bin directory, so that PATH is the only env. variable, which has to be set
9301 in case of standard installation.

10379 ram so more space is available.
10381 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10384 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10385 not bytes. Function summary() which creates a memory usage summary
10386 file with extension .mem. Reports of overlaping stack and small stack
10387 size. If the space for the stack is less than 16 bytes aslink trows a
10390 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10391 the 8051. Option 'y' for memory summary output file.
10393 Changes to sdcc (All the changes are marked with 'JCF'):
10395 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10397 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10398 overlaying area for it (uses RegBankUsed[4]).
10400 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10401 bank zero as used by default. By default aslink locates the stack
10402 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10403 the creation of the .mem file. Delegates the allocation of data area
10404 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10405 the begining of the stack area to aslink.
10407 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10408 glue() in SDCCglue.c creates an area for it.
10410 2002-09-03 Borut Razem <borut.razem AT siol.net>
10411 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10412 sdcc/src/pic/glue.c:
10413 introduced atexit() handler for teporay files removal in case of
10414 errors, assertions, ...
10416 2002-08-29 Borut Razem <borut.razem AT siol.net>
10417 * sdcc/support/cpp2/auto-host_vc_in.h:
10418 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10419 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10420 Maybe there is a similar problem with BORLANDC? It should be checked!
10422 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10423 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10424 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10425 was not executed, and the compiler (cl) launched a warning:
10426 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10428 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10429 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10431 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10432 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10434 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10435 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10436 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10437 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10438 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10439 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10440 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10441 - added Release configuration in VS projects
10442 - review of compiler an linker options
10443 - VC .exe files are generated in bin_vc directory, not to interfere
10444 with binaries generated from other projects (cygwin, mingw, bcc ...)
10446 * sdcc/src/yacc.dsp: added
10448 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10449 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10450 and insert the version number definitions from .version
10452 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10454 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10455 added - genarate auto-host.h using auto-host_vc_in.h as template
10458 removed from CVS, generated automatically
10460 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10461 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10463 2002-08-11 Borut Razem <borut.razem AT siol.net>
10464 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10466 2002-08-10 Borut Razem <borut.razem AT siol.net>
10467 * src/SDCCmain.c (main):
10468 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10469 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10470 The consequence was that some temporary files were not removed.
10473 unification of code in functions tempfilename() and tempfile():
10474 function tempnam() is defined in Visual Studio 6.0 and .NET
10476 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10478 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10479 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10480 - removed compiler command line option /WX: Treats all warnings as errors
10481 - update a list of source files, included into the project
10483 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10484 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10485 changed project type to Generic Project so that can be correcly converted to VS.NET project
10487 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10489 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10491 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10493 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10494 added return 0 statements after assert() to make compiler happy
10496 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10497 added newline in the def file to keep MSC compiler satisfied
10499 * sdcc/src/z80/gen.c:
10500 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10501 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10502 - solved MSC error in function aopDump()
10504 * sdcc_vc.h: define PREFIX as "\\sdcc"
10506 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10507 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10555 Added -p option. Allows port dependent processor to be specified.
10558 Initialized the new field char *Processor field to NULL in all ports
10561 Compiler generated registers for interrupt context saving
10562 were not getting allocated.
10564 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10567 Fixed left shift. Will promote the left side of a left shift
10568 if a) left shifting more than size of operand or b) when assigned

10679 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10681 * sdcc/src/SDCCloop.c:
10682 Previous fix was not good. basic blocks that have "break" or "return" are
10683 not really partof a loop , but live ranges used in these blocks should
10684 be live thru the entire loop, so set partOfLoop but don't add them to
10687 2002-02-21 <johan AT FRIJA>
10689 * src/SDCCcse.c: fixed bug #514308
10691 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
