888 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
890 Enabled VPATH feature: changed nearly all Makefiles (149 files).
891 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
893 One basic decision: e.g. src/clean.mk includes further files. In order
894 to make this work there are two solutions:
895 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
896 run configure on them. This way they can use
897 'include $(srcdir)/port-clean.mk'
898 - always include clean.mk by the Makefile at the same level. To avoid
899 that `make clean` tries to include and build Makefile.dep the
900 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
901 implemented, because now even `make uninstall` doesn't create
902 Makefile.in. clean.mk could be eliminated by pasting it in
905 * debugger/mcs51/Makefile.in: build own objects from library sources
906 (SLIB, SDCC) in current directory
908 * configure, configure.in: renamed --disable-device-lib-build in
909 --disable-device-lib; added --enable-doc, the required tools are
910 searched by configure; added result message; the toolchain for the
911 belonging ports are now only built, if the port is enabled.
913 * support/regression/*: all output is written in directory gen, because
914 the fwk and ports directories don't livet in the build tree using vpath
916 * doc/sdccman.lyx: renamed --disable-device-lib-build to
917 --disable-device-lib, added --enable-doc, added section VPATH
919 * sim/ucsim/configure.in,
920 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
921 z80 are enabled by default
923 2006-04-24 Raphael Neider <rneider AT web.de>
925 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
926 to config word, "pic14_"-prefixed some extern functions
927 (pic14_emitConfigWord): emit __config directive(s) if assignment to
928 config word has been found
929 * src/pic/device.h: added prototypes
930 * src/pic/pcode.c: added "pic14_"-prefix where needed
931 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
933 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
935 (pic14emitRegularMap): ignore config words,

1171 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1173 * src/mcs51/gen.c (genCall): fixed bug 1457608
1175 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1194 implemented patch 1120823 Thanks to Willy De la Court (normal
1195 interrupts need an interrupt number now if they are made critical),
1196 and enabled nesting of critical functions though not for gbz80
1197 (genCritical, genEndCritical): added functions
1198 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1199 * src/z80/mappings.i: added "ei" to all mappings

1208 2006-03-16 Raphael Neider <rneider AT web.de>
1210 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1211 the left operand is shorter than the result (c* = lit-c* + int),
1213 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1216 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1218 * src/.version: increased version number to 2.5.5
1219 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1220 linking is done manually in pic16 port's _linkEdit,
1221 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1222 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1223 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1224 allocate asmop as AOP_ACC,
1225 (aopForRemat): added parameter 'bool result' in function declaration,
1226 (pic16_aopGet): return AOP_ACC when accessing WREG,
1227 (pic16_popGetTempReg): minor modification,

1238 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1239 call to allocReg, not by manually allocating a new one,
1240 (pic16_assignRegisters): now before going through the register
1241 allocating functions mark all registers as free. This eliminates some
1242 side effects resulting from peephole parser done earlier in the backbone
1244 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1294 2006-03-06 Borut Razem <borut.razem AT siol.net>
1296 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1297 made the linker quiet
1299 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1301 * src/pic16/gen.c (genPcall): fixed bug #1443644
1302 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1303 which dumps before the function entry point a data byte which represents
1304 the number of the local variables used by the specified function, added
1305 'xinst' for initial support for Extended Instruction Support,
1306 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1307 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1308 port->fun_prefix anymore (may change later),
1309 (genFunction, genEndFunction): do not store/restore local registers for
1310 _main (this should take care the --main-return command line option in
1312 (genOr): removed some legacy pic-port instructions,
1313 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1314 performing operations with SFR's causes data to be written more than
1315 once to each SFR. Perhaps SFRs should be handled in special cases...
1316 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1318 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1319 into account for stack starting position,

1321 --extended or -y for Extended Instruction Support,
1322 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1323 (deassignLRs): *** perhaps the most important change, old 'for' code
1324 (commented out for reference), didn't account for some registers which
1325 were left marked 'not free' after a pointer operation. The change
1326 reduces register usage a lot in some cases
1328 2006-03-04 Borut Razem <borut.razem AT siol.net>
1330 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3599 * src/SDCCglobal.h (struct options),
3601 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3602 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3603 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3604 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3605 always available in leading double underscore form. The C99 support is
3606 mostly missing, but it's a start.
3607 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3608 reserved identifier "__data".

3686 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3688 * device/lib/printf_large.c: removed inline assembly for portability and
3689 readability. Use printf_fast if speed or size are more important.
3690 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3691 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3693 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3695 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3696 prevent compiler warning
3698 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3700 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3701 moved to level 0 and declared as static. Also they are explicit
3702 placed in access bank. This was necessery because some times they
3703 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3704 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3705 optimizations. Currently only compare to unsigned char is implemented,
3706 * src/pic16/gen.c: added fReturnIdx array,
3707 * (struct resolvedIfx) is moved to gen.h and made public,
3708 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3709 * (aopForSym): added an optimization to directly store in stack of
3710 the operand of a SEND iCode,
3711 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3712 but as registers instead (AOP_REG) using the fReturnIdx array,
3713 * (pic16_freeAsmop): remove the freed register from the
3714 _G.sregsAlloc field,
3715 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3716 a compare of 'WREG',
3717 * (pic16_popGetTempRegCond): changed function prototype, now
3718 function takes also a bitVector argument v which holds the current
3719 set of registers that are allocated for stack access by aopForSym,
3720 registers allocated in aopForSym for accessing stack symbols are not
3721 any more part of the functions usedRegs field,
3722 * (genCall): some times aopOp is called for a stack variable to be
3723 send, aopForSym might perform the push, if this is true make sure
3724 that genCall doesn't push the variable twice by testing _G.resDirect,
3725 * (genFunction): changed testing for unspecified interrupt number
3726 from 256 to INTNO_UNSPEC,
3727 * modified selection scheme of frame pointer generation. Previously
3728 if function did use local registers a frame pointer was generated,
3729 now a frame pointer is generated only if function has arguments
3730 (that need PLUSW2 register access), or has stack arguments, or the
3731 compiler is not instructed to omit the frame pointer,
3732 * (genEndFunction): before restoring local registers that were saved
3733 in the function preamble, also restore the registers that *might*
3734 have been allocated for stack access,
3735 * (genRet): removed some old comments,
3736 * (genCmp, the active (RN's) version): added a call to the
3737 pic16_genCmp_special function to perform the compare with a more
3738 robust and optimized way,
3739 * (genInline): a feature has been added in inline code generation,
3740 which allows a wildcard variable substitution when writing inline
3741 assembly. Code is incomplete and experimental therefore undocumented,
3742 * (genCast): changed order of aopOp for result and right to allow
3743 aopForSym to directly load the result if possible,
3744 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3745 perform an optimized compare on some selected special occasions,
3746 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3747 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3748 generate an IVT any more,
3749 * src/pic16/main.c (pic16_optionsTable): added command line option
3751 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3752 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3754 * src/pic16/NOTES: Raphael Neider added in list of active developers
3755 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3756 jumptable_end to prevent bug #,
3757 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3758 inCond and outCond fields,
3759 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3760 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3761 turn off register spilling,
3762 * (packRegsForOneUse): synced with other ports' versions although it
3763 is not used currently,
3764 * (pic16_packRegisters): added an optimization while reading
3765 structure bitfields, some registers may be saved (malloc code is
3766 decreased by 80 bytes)
3768 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3770 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3771 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3772 this can be optimized more?
3774 2005-03-10 Raphael Neider <rneider AT web.de>
3776 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3777 genNearPointerGet): (hopefully) fixed access to bitfields via
3778 pointers (p->bitN = x; and x = p->bitN; failed)
3780 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4412 Adding support for replacing ljmps with sjmps in jumptables
4413 generated for switch statements. For now you need to set the
4414 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4415 Now 4 algorithms for mcs51 jumptable generation are used:
4416 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4417 addresses loaded pc-relative for up to 112 cases and stack-pushing
4418 target addresses loaded with offset from dptr for up to 256 cases.

4445 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4446 to call when a stack overflow occurs,
4447 * (malloc.h): added CVS Id tag,
4448 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4450 * added libc directory. The current version of LibC contains string
4451 functions, ctype functions and macros and some functions of the
4452 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4453 be extensively tested in the future. Standard disclaimer here.
4454 Library is not automatically build yet. But one can build it by
4455 invoking 'make' inside the libc directory.
4456 * added ADC library under libio. Preliminary version yet.

4462 temporary registers, its a buggy feature and will be removed,
4463 * (pic16_popGet): set register instance field in AOP_CRY,
4464 * (pic16_outBitC): fixed for results in size greater than 1,
4465 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4466 * (pic16_storeForReturn): optimized return of 0,
4467 * (genCmp): experimental code for new genCmp which uses PIC18's
4468 special compare&skip instructions. Initial tests fail some times
4469 with variables grater than 1 byte in size, so new code is disabled,
4470 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4472 * (genCast): began a fix to optimize the casting of a bit to another
4473 bit, now assigning a bitfield to another bitfield will fail, sorry,
4474 * src/pic16/main.c: disabled the use of lr-support feature,
4475 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4478 bits with offset (case PO_GPR_BIT),
4479 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4481 * (isBankInstruction): modified to return 0 for no banking instruction,
4482 and 1 for banking instruction,
4483 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4484 caused stop processing pCodes after a inline assembly block,
4485 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4486 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4487 registers when it shouldn't,
4488 * src/pic16/ralloc.c (allocReg): add preliminary support for
4489 supporting a limited set of temporary registers,
4491 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4493 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4494 genDataPointerSet): ensure assignments always copy in MSB to LSB
4496 (loadRegFromAop): recognize CLRH optimization,
4497 (genFunction): optimize RECEIVE iCodes in reentrant functions
4499 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4501 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7428 * src/pic/glue (pic14emitRegularMap),
7429 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
7431 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
7433 * src/pic/pcode.c (PCodeID): commented out left over debug code
7435 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
7437 * support/valdiag/tests/overflow.c: added shift tests
7445 * src/pic/pcodepeep.c,
7446 * src/pic/pcoderegs.c,
7448 * src/pic/ralloc.h: applied patch from Slade Rich;
7449 added support for multiple code pages and multiple RAM banks on the
7450 PIC 14 port. The ASM files now no longer simply assume all the
7451 code / RAM are in the same page / bank. This means the linker can
7452 safely allocate code/RAM of separate ASM files to different pages/banks.
7453 * doc/sdccman.lyx: added Slade's tips
7454 * src/mcs51/peeph.def: fixed bug #880768

7463 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
7466 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7467 strtof is not part of C89 and isn't included with Mac OS X.
7469 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7471 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7496 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7498 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7499 loaded with the linker search paths (-L arguments) and the libraries
7500 to be linked with the current source (-l arguments). Changes
7501 currently will affect only the pic16 port.
7502 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7503 include path the port specific paths and port specific libraries,
7504 * gplink command now contains the $3 argument,
7505 * src/pic16/device.h,
7506 * src/pic16/device.c,: structure PIC_device is made public and
7507 renamed to PIC16_device, the same for variable Pics which is renamed
7508 to Pics16. Updated all references to them.
7509 * src/pic16/glue.c (pic16glue): corrected bug with code
7510 initialization which bypassed the variable initializations block.

7522 Documenting changes from previous commits.
7523 * configure.in (version 1.56),
7524 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7525 when generating output files to configure the pic16 library,
7526 but now I've commented it out, since gputils aren't installed in the
7527 SF compile farm, so library won't compile
7529 * device/lib/Makefile.in (version 1.56): initially I've added in
7530 target 'all' the prerequestive 'model-pic16' so it compiled the
7531 pic16 library, but now I've commented it out for the same reasons
7533 * added targets 'model-pic16' and 'objects-pic16' to compile the
7535 * added target 'port-specific-objects-pic16' to handle the
7536 generated libraries and copy them into the build/ directory
7537 * added target 'clean-intermediate-pic16' to clean intermediate
7538 files into pic16 directory
7539 * in target 'installdirs' added line to create directory pic16 in
7540 the installation path
7542 * device/include/Makefile.in (version 1.11): in target 'install'
7543 added lines to copy all header files to installation path,
7544 * in target 'installdirs' added line create directory for pic16
7545 headers in the installation path

7560 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7561 option so that it actually works. Made it specific to the z80, since
7562 the gbz80 doesn't have these kinds of I/O ports.
7564 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7566 * device/include/z180.h,

7588 Mainly changes to support compilation of the device libraries
7589 * src/pic16/device.c: stack is allocated via symbol and not
7590 via literal number. The symbol is placed in the corresponding
7591 position of the data ram
7592 * (pic16_dump_section): relocatable and absolute uninitialized
7593 data are now emitted in sorted order to reduce section naming,
7594 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7595 weren't marked as being in the access bank,
7597 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7599 Added portion of GNU PIC Library under the directory
7600 device/include/pic16 and device/lib/pic16. These files
7601 contain the declarations of SFRs for the PIC18Fxx2 devices.
7602 The directory is initialized via configure from toplevel.
7604 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7606 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

7632 all over. Telling LaTeX to be less strict with word spacing
7633 to better keep the right margin. Changed some notes about
7634 maintainance of the ports in section 3.2.1 - is it OK like this?
7636 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7674 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7676 * src/pic16/peeph.def: all peepholes with movff are commented out,
7677 because there is a problem in the pcode peep optimizer,
7678 * src/pic16/ralloc.c: the register allocator can now reuse local

7830 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7832 PIC16 port related changes:
7833 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7834 added variable stackPos,
7836 * gen.c: genCall, assignResultValue: added support for
7837 pushing/retrieving function parameters to/from stack,
7838 genFunction,genEndFunction: setup stack frame for the
7840 genAddrOf: will be changed according to bug 863624
7842 * added files genutils.c and genutils.h which contain gen*
7843 debugged and optimised functions extracted from gen.c
7845 * glue.c: added variable 'externs' which holds extern symbols,
7846 pic16emitRegularMap: is modified to properly handle relocatable
7847 symbols under the new scheme,
7848 pic16createInterruptVect: is modified
7849 pic16printPublics: is modified to emit 'global' assembler directives,
7850 added pic16_printExterns to print extern symbols,
7851 pic16glue: initializes stack/frame pointer in the beginning of
7852 the assembly output. Temporary hack, will be corrected later,
7853 because gplink yet does not support stack and SDCC does not
7854 yet support a type of crt0.o object to create the final binary.
7856 * Removed many lines that contain 8051 legacy code.
7857 * The code is finally placed under a 'code' directive.
7858 * Added port specific options.
7860 * _process_pragma: simplified since now we do not need *special*
7861 include file to define SFR registers. But a separate header
7862 will be needed. This will be developed later.
7863 * _pic16_parseOptions: added, parses port specific options:
7864 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7865 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7866 --preplace-udata-with=
7868 * _pic16_setDefaultOptions: modified to initialize section names,
7869 but hack is temporarly out of order since it needs improvement.
7870 * _pic16_genAssemblerPreamble: configuration words are emitted by
7871 their address instead of their name. This part is incomplete and
7872 supports only the 18Fxx2 devices. Other devices will emit an error
7873 during assembly since they do not contain the same set of config
7875 * _pic16_genIVT: is modified,
7877 * pcode.c: added definitions for some hardware registers that are needed
7879 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7880 All PCI entries are updated. Now LFSR is supported.
7881 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7882 * added pic16_newpCodeOpLit2 to support instructions with
7883 two literal arguments
7884 * pic16_pCode2str: corrected code that emits assembler instructions
7885 with two literal operands and those that have an access bit modifier
7886 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7887 this fixes a bug which caused some labels to be lost, when an
7888 assembler directive was added, i.e. banksel,
7889 * pic16_FixRegisterBanking: improved logic that causes the insertion
7891 * InlineFunction: functions that are called once, are not any more
7892 inlined. This can be a port option in the future,
7894 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7896 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7897 hold the corresponding uninitialized symbols,
7898 * pic16_allocProcessorRegister: registers have explicit marked the
7900 * pic16_allocInternalRegister: registers are explicit marked as
7902 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7903 processing list, so bit registers were lost,
7906 * ralloc.h: added field 'accessBank' and original symbol operand
7907 in register definition,
7908 * removed the field isMapped from register definition,
7910 ** Several functions have been removed from various sources:
7911 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7912 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7913 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7914 pic16_assignRelocatableRegisters
7916 ** others have been introduced:
7917 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7918 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7920 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7922 * support/scripts/inc2h.pl: changed definition of BIT_AT
7923 to emit 'sbit at' instead of 'bit at'. This was a request.
7925 PIC16 port related preliminary changes:
7926 * gen.c: prefixed function popRegFromString with
7927 pic16_ and all references to it corrected
7928 * pcode.c: all pic16_pc_* hardware registers prefixed
7929 with underscore (_),
7930 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7931 * ralloc.c: newReg(): when register is REG_SFR then
7932 set address to rIdx,
7933 pic16_allocProcessorRegister(): marks register wasUsed=0
7934 pic16_writeUsedRegs(): added a call to assign processor
7935 registers via pic16_assignFixedRegisters
7937 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7939 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7940 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7941 variables in unused register banks. Also the SSEG is placed
7942 wherever there is enough space for it, and IDATA can be anywhere
7943 in internal RAM. For now compile using -Wl-Y[stack_size].
7944 The mem file is different for this option as well, since it
7945 makes no sense of talking about DSEG lenght.
7947 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7949 * src/SDCClrange.c: fixed bug 869095 that caused segfault

8194 * src/SDCCast.c (decorateType): disabled a transformation I added in
8195 revision 1.188 (access to fields of a structure at an absolute address);
8196 it breaks with bitfields, extern declarations, and gcse analysis.
8197 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8198 could be assigned through a pointer, so don't complain.

8922 reported in bug #800609
8924 2003-09-04 Vangelis Rokas <vrokas AT otenet.gr>
8926 * Top header beautifications in src/pic16 directory:
8927 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
8928 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
8929 pcoderegs.h, ralloc.c, ralloc.h
8930 * main.c: added top header and GPL license notice
8931 * pcode.c: fixed the if-conditional warning
8933 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
8935 * device/lib/_mullong.c: replaced int by short for gcc
8937 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8939 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
8940 and JUMPTABLE iCodes properly now (worked by accident before)
8941 * src/mcs51/gen.c (leftRightUseAcc),
8942 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
8943 iCode properly now. Use getSize instead of nRegs since a & b
8944 aren't part of the nRegs tally.
8946 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
8948 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
8949 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
8950 before instructions that use the _STATUS register
8952 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
8954 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8955 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8956 fetching of the pointer
8957 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8958 copied from genNearPointerSet()
8959 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8960 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8961 If they pop r0/r1 they must be called in the opposite order than aopOp().
8962 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8963 (resp. --stack-auto), prepared for --xstack
8965 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

8969 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8971 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
8972 these ports have their own __sdcc_external_start()
8974 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8976 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8977 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8978 type for bits was changed. It resulted in bit variables becoming
8979 global, which is not permitted in PIC 14 assembly output.
8981 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8983 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8985 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8987 Z80 and MCS51 linkers complaint if a public symbol is defined
8988 in more than one library module:
8992 * as/mcs51/Makefile.in
8994 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8996 A few small changes that speed up the peephole optimizer.
9000 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9002 Try to make the peephole optimizer smarter by maintaining
9003 an association between the assembly source code and the
9004 iCodes that originated them. Put this information to use
9005 with a new peephole rule condition "notVolatile" so that
9006 the rules can be aggressive yet still safe.
9011 * src/mcs51/peeph.def
9013 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9017 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9018 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9019 if the left or right operand symbols have the accuse flag set.
9021 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9023 Changed the type of the result of the ! (NOT) operator to char;
9024 previously it returned the same type as the source. This allows
9025 us to eliminate all the genFloatNot functions (all of its target
9026 implementations were very buggy) since !float can use the same
9029 * src/SDCCicode.c (ast2iCode): ! returns char
9030 * src/mcs51/gen.c (genNot, genNotFloat),
9031 * src/ds390/gen.c (genNot, genNotFloat),
9032 * src/z80/gen.c (genNot, genNotFloat),
9033 * src/pic/gen.c (genNot, genNotFloat),
9034 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9036 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9038 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9039 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9040 during interrupts. Ensure WSAVE is located at a shared bank address.
9041 2. Fixed page selection in some places
9042 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9043 the registers name strings.
9044 4. Fixed "signed / unsigned compare" compiler warnings.
9045 5. The PIC port manages its own allocation of the general purpose
9046 registers, but makes no attempt to reuse them. As a result when
9047 compiling it soon runs out of general purpose registers. Some
9048 additional code was added to the files pcode.c and device.c to walk
9049 through the function call tree and rename the registers so that they
9059 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9060 genPlus() & genMinus() when the result is the same as left or right
9062 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9066 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9068 Made bitfield a distinct type from bit so that bitfields
9069 convert as per ANSI C and bits retain their traditional
9070 boolean style behaviour. Implemented bitfield support in
9078 * src/ds390/gen.c: bit v bitfield split
9079 * src/z80/gen.c: New support for bitfields
9080 * support/regression/tests/bitfields.c: reenabled z80,
9083 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9085 Rules 246.x, 247.x relate to bitfields, the others speed up
9086 access to xdata mapped I/O devices.
9088 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9090 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9092 Cleaned up genPackBits and genUnpackBits and added two helper
9093 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9094 for literal assignments in genPackBits (thanks to Frieder for
9100 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9102 Fixed bug #748310 (pointer to function type mishandled when the
9103 function name is omitted). Also fixed a SIGSEGV when a function
9104 attribute (reentrant, etc) is used on a non-function or on a
9105 function but misplaced before the parameter list.
9107 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9109 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9110 * support/Util/SDCCerr.h,
9111 * support/Util/SDCCerr.c: Added func attr misuse error msg
9113 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9115 Fixed bug #787649 by anonymous
9116 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

9132 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9134 Made the constant following the "interrupt" keyword optional. If
9135 omitted, the function will not automatically be given an entry
9136 in the interrupt vector table (similar to #pragma NOIV, but
9137 less syntacticly kludgy). The interrupt number is also now
9138 range checked. Also fixed a bug in the high order bit example
9145 * support/Util/SDCCerr.c
9146 * support/Util/SDCCerr.h
9149 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9152 * src/SDCCicode.c (operandOperation): rewritten some ops
9153 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9154 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9156 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9157 be re-activated by defining REDUCE_LITERALS)
9158 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9159 unsigned, but are signed by default
9160 * src/SDCCval.c (constVal): rearranged
9161 * src/SDCCval.c (valMod): preliminary fix
9162 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9205 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9206 * src/SDCCval.c (valDiv, valMod): fixed signdness
9207 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9208 signedness of modulo, left and right shift

9614 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9615 the regression tests I'm not brave enough to enable 245.b, 245.c
9616 * doc/sdccman.lyx: added latex preamble for hyperref package.
9617 Using pdflatex this will give you a hyperlinked pdf file with
9618 bookmarks. (prepend '%' before /usepackage if this breaks something)

9656 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9658 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9659 it can be defined with CFLAGS when running configure
9660 * src/SDCCmain.c: fixed compiling + linking with object files
9662 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9665 added --disable-pic16-port
9666 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9667 * src/SDCCmain.c: linkOptions is changed to set *,
9668 added if/endif conditional macros to remove options help
9669 messages from optionsTable when a port is not configured, added
9670 support for the PIc16 port in the ports table, when executing
9671 the compiler with no port specified on command line, a default
9672 port is selected with the new macro DEFAULT_PORT which is
9673 defined in port.h, in setDefaultOptions() linkOptions is removed
9674 from initialization assignment, since now it is a set,
9675 parseCmdLine uses setParseWithComma for linkOptions, in
9676 linkEdit() linkOptions are accessed with new function indexSet()
9677 which returns the i'th item of a set variable. See SDCCset.c, in
9678 linkEdit() when calling buildCmdLine(), added linkOptions as
9679 last argument. Now users can pass arguments to gplink via the
9680 -Wl option, main() uses pic16glue() to glue up pic16 programs

9692 * src/pic16/glue.c: commented out some error producing lines
9693 * src/pic16/main.c: __config directives are commented out to stop
9694 gpasm complaining and test the linkage with gplink, _linkCmd and
9695 _asmCmd changed to be more gplink and gpasm friendly
9696 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9697 produced an error when parsed, peep rule 12 is added to utilize
9698 movff, but it is commented out since the pCode does not support
9699 yet a command with 2 address arguments
9701 2003-05-18 <johan AT balder>
9703 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9728 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9730 2003-05-11 Borut Razem <borut.razem AT siol.net>
9732 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9733 the path of bin directory, so that PATH is the only env. variable, which has to be set
9734 in case of standard installation.
9735 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10807 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10810 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10811 area BSEG. Also moves, if possible, the DATA area down into the internal
10812 ram so more space is available.
10814 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10817 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10818 not bytes. Function summary() which creates a memory usage summary
10819 file with extension .mem. Reports of overlaping stack and small stack
10820 size. If the space for the stack is less than 16 bytes aslink trows a
10823 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10824 the 8051. Option 'y' for memory summary output file.
10826 Changes to sdcc (All the changes are marked with 'JCF'):
10828 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10830 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10831 overlaying area for it (uses RegBankUsed[4]).
10833 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10834 bank zero as used by default. By default aslink locates the stack
10835 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10836 the creation of the .mem file. Delegates the allocation of data area
10837 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10838 the begining of the stack area to aslink.
10840 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10841 glue() in SDCCglue.c creates an area for it.
10843 2002-09-03 Borut Razem <borut.razem AT siol.net>
10844 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10845 sdcc/src/pic/glue.c:
10846 introduced atexit() handler for teporay files removal in case of
10847 errors, assertions, ...
10849 2002-08-29 Borut Razem <borut.razem AT siol.net>
10850 * sdcc/support/cpp2/auto-host_vc_in.h:
10851 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10852 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10853 Maybe there is a similar problem with BORLANDC? It should be checked!
10855 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10856 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10857 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10858 was not executed, and the compiler (cl) launched a warning:
10859 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10861 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10862 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10864 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10865 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10867 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10868 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10869 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10870 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10871 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10872 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10873 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10874 - added Release configuration in VS projects
10875 - review of compiler an linker options
10876 - VC .exe files are generated in bin_vc directory, not to interfere
10877 with binaries generated from other projects (cygwin, mingw, bcc ...)
10879 * sdcc/src/yacc.dsp: added
10881 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10882 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10883 and insert the version number definitions from .version
10885 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10887 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10888 added - genarate auto-host.h using auto-host_vc_in.h as template
10891 removed from CVS, generated automatically
10893 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10894 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10896 2002-08-11 Borut Razem <borut.razem AT siol.net>
10897 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10899 2002-08-10 Borut Razem <borut.razem AT siol.net>
10900 * src/SDCCmain.c (main):
10901 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10902 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10903 The consequence was that some temporary files were not removed.
10906 unification of code in functions tempfilename() and tempfile():
10907 function tempnam() is defined in Visual Studio 6.0 and .NET
10909 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10911 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10912 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10913 - removed compiler command line option /WX: Treats all warnings as errors
10914 - update a list of source files, included into the project
10916 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10917 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10918 changed project type to Generic Project so that can be correcly converted to VS.NET project
10920 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10922 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10924 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10926 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10927 added return 0 statements after assert() to make compiler happy
10929 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10930 added newline in the def file to keep MSC compiler satisfied
10932 * sdcc/src/z80/gen.c:
10933 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10934 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10935 - solved MSC error in function aopDump()
10937 * sdcc_vc.h: define PREFIX as "\\sdcc"
10939 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10940 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10977 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10979 2002-03-28 Johan Knol <johan AT balder>
10981 * src/SDCCval.c: fixed bug #532436
10983 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10985 Added "char *Processor" field to the port structure.
10988 Added -p option. Allows port dependent processor to be specified.
10991 Initialized the new field char *Processor field to NULL in all ports
10994 Compiler generated registers for interrupt context saving
10995 were not getting allocated.
10997 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11000 Fixed left shift. Will promote the left side of a left shift
11001 if a) left shifting more than size of operand or b) when assigned
11002 to something size > size of left side

11112 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11114 * sdcc/src/SDCCloop.c:
11115 Previous fix was not good. basic blocks that have "break" or "return" are
11116 not really partof a loop , but live ranges used in these blocks should
11117 be live thru the entire loop, so set partOfLoop but don't add them to
11120 2002-02-21 <johan AT FRIJA>
11122 * src/SDCCcse.c: fixed bug #514308
11124 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
