873 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
875 Enabled VPATH feature: changed nearly all Makefiles (149 files).
876 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
878 One basic decision: e.g. src/clean.mk includes further files. In order
879 to make this work there are two solutions:
880 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
881 run configure on them. This way they can use
882 'include $(srcdir)/port-clean.mk'
883 - always include clean.mk by the Makefile at the same level. To avoid
884 that `make clean` tries to include and build Makefile.dep the
885 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
886 implemented, because now even `make uninstall` doesn't create
887 Makefile.in. clean.mk could be eliminated by pasting it in
890 * debugger/mcs51/Makefile.in: build own objects from library sources
891 (SLIB, SDCC) in current directory
893 * configure, configure.in: renamed --disable-device-lib-build in
894 --disable-device-lib; added --enable-doc, the required tools are
895 searched by configure; added result message; the toolchain for the
896 belonging ports are now only built, if the port is enabled.
898 * support/regression/*: all output is written in directory gen, because
899 the fwk and ports directories don't livet in the build tree using vpath
901 * doc/sdccman.lyx: renamed --disable-device-lib-build to
902 --disable-device-lib, added --enable-doc, added section VPATH
904 * sim/ucsim/configure.in,
905 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
906 z80 are enabled by default
908 2006-04-24 Raphael Neider <rneider AT web.de>
910 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
911 to config word, "pic14_"-prefixed some extern functions
912 (pic14_emitConfigWord): emit __config directive(s) if assignment to
913 config word has been found
914 * src/pic/device.h: added prototypes
915 * src/pic/pcode.c: added "pic14_"-prefix where needed
916 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
918 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
920 (pic14emitRegularMap): ignore config words,
921 (pic14createInterruptVect): moved generating __config directives away
922 (picglue): have __config directives emitted
924 2006-04-24 Borut Razem <borut.razem AT siol.net>
926 * doc/Makefile: sync with nightly build makefile
928 2006-04-24 Raphael Neider <rneider AT web.de>

931 registers that have not been assigned proper liveranges,
932 fixes #1469504 and #1474602,
933 (pCodeRegOptimizeRegUsage): fixed typo in comment
935 2006-04-24 Borut Razem <borut.razem AT siol.net>
937 * device/examples/main8051.c: deleted - it was removed from CVS
938 24.mar.2000 and after that modified 18.feb.2001, so it reappered
939 after the transition to Subversion
940 * src/SDCCalloc.h: deleted - it was removed from CVS

1180 interrupts need an interrupt number now if they are made critical),
1181 and enabled nesting of critical functions though not for gbz80
1182 (genCritical, genEndCritical): added functions
1183 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1184 * src/z80/mappings.i: added "ei" to all mappings

1196 the left operand is shorter than the result (c* = lit-c* + int),
1198 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1201 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1203 * src/.version: increased version number to 2.5.5
1204 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1205 linking is done manually in pic16 port's _linkEdit,
1206 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1207 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1208 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1209 allocate asmop as AOP_ACC,
1210 (aopForRemat): added parameter 'bool result' in function declaration,
1211 (pic16_aopGet): return AOP_ACC when accessing WREG,
1212 (pic16_popGetTempReg): minor modification,

1223 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1224 call to allocReg, not by manually allocating a new one,
1225 (pic16_assignRegisters): now before going through the register
1226 allocating functions mark all registers as free. This eliminates some
1227 side effects resulting from peephole parser done earlier in the backbone
1229 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1279 2006-03-06 Borut Razem <borut.razem AT siol.net>
1281 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1282 made the linker quiet
1284 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>

1287 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1288 which dumps before the function entry point a data byte which represents
1289 the number of the local variables used by the specified function, added
1290 'xinst' for initial support for Extended Instruction Support,
1291 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1292 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1293 port->fun_prefix anymore (may change later),
1294 (genFunction, genEndFunction): do not store/restore local registers for
1295 _main (this should take care the --main-return command line option in
1297 (genOr): removed some legacy pic-port instructions,
1298 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1299 performing operations with SFR's causes data to be written more than
1300 once to each SFR. Perhaps SFRs should be handled in special cases...
1301 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1303 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1304 into account for stack starting position,
1305 (struct OPTIONS pic16_optionsTable): added command line argument
1306 --extended or -y for Extended Instruction Support,
1307 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1308 (deassignLRs): *** perhaps the most important change, old 'for' code
1309 (commented out for reference), didn't account for some registers which
1310 were left marked 'not free' after a pointer operation. The change
1311 reduces register usage a lot in some cases
1313 2006-03-04 Borut Razem <borut.razem AT siol.net>
1315 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3586 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3587 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3588 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3589 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3590 always available in leading double underscore form. The C99 support is
3591 mostly missing, but it's a start.
3592 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3593 reserved identifier "__data".
3595 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3671 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3673 * device/lib/printf_large.c: removed inline assembly for portability and
3674 readability. Use printf_fast if speed or size are more important.
3675 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3676 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3678 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3680 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3681 prevent compiler warning
3683 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3685 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3686 moved to level 0 and declared as static. Also they are explicit
3687 placed in access bank. This was necessery because some times they
3688 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3689 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3690 optimizations. Currently only compare to unsigned char is implemented,
3691 * src/pic16/gen.c: added fReturnIdx array,
3692 * (struct resolvedIfx) is moved to gen.h and made public,
3693 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3694 * (aopForSym): added an optimization to directly store in stack of
3695 the operand of a SEND iCode,
3696 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3697 but as registers instead (AOP_REG) using the fReturnIdx array,
3698 * (pic16_freeAsmop): remove the freed register from the
3699 _G.sregsAlloc field,
3700 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3701 a compare of 'WREG',
3702 * (pic16_popGetTempRegCond): changed function prototype, now
3703 function takes also a bitVector argument v which holds the current
3704 set of registers that are allocated for stack access by aopForSym,
3705 registers allocated in aopForSym for accessing stack symbols are not
3706 any more part of the functions usedRegs field,
3707 * (genCall): some times aopOp is called for a stack variable to be
3708 send, aopForSym might perform the push, if this is true make sure
3709 that genCall doesn't push the variable twice by testing _G.resDirect,
3710 * (genFunction): changed testing for unspecified interrupt number
3711 from 256 to INTNO_UNSPEC,
3712 * modified selection scheme of frame pointer generation. Previously
3713 if function did use local registers a frame pointer was generated,
3714 now a frame pointer is generated only if function has arguments
3715 (that need PLUSW2 register access), or has stack arguments, or the
3716 compiler is not instructed to omit the frame pointer,
3717 * (genEndFunction): before restoring local registers that were saved
3718 in the function preamble, also restore the registers that *might*
3719 have been allocated for stack access,
3720 * (genRet): removed some old comments,
3721 * (genCmp, the active (RN's) version): added a call to the
3722 pic16_genCmp_special function to perform the compare with a more
3723 robust and optimized way,
3724 * (genInline): a feature has been added in inline code generation,
3725 which allows a wildcard variable substitution when writing inline
3726 assembly. Code is incomplete and experimental therefore undocumented,
3727 * (genCast): changed order of aopOp for result and right to allow
3728 aopForSym to directly load the result if possible,
3729 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3730 perform an optimized compare on some selected special occasions,
3731 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3732 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3733 generate an IVT any more,
3734 * src/pic16/main.c (pic16_optionsTable): added command line option
3736 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3737 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3739 * src/pic16/NOTES: Raphael Neider added in list of active developers
3740 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3741 jumptable_end to prevent bug #,
3742 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3743 inCond and outCond fields,
3744 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3745 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3746 turn off register spilling,
3747 * (packRegsForOneUse): synced with other ports' versions although it
3748 is not used currently,
3749 * (pic16_packRegisters): added an optimization while reading
3750 structure bitfields, some registers may be saved (malloc code is
3751 decreased by 80 bytes)
3753 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3755 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3756 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3757 this can be optimized more?
3759 2005-03-10 Raphael Neider <rneider AT web.de>
3761 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3762 genNearPointerGet): (hopefully) fixed access to bitfields via
3763 pointers (p->bitN = x; and x = p->bitN; failed)

4397 Adding support for replacing ljmps with sjmps in jumptables
4398 generated for switch statements. For now you need to set the
4399 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4400 Now 4 algorithms for mcs51 jumptable generation are used:
4401 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4402 addresses loaded pc-relative for up to 112 cases and stack-pushing
4403 target addresses loaded with offset from dptr for up to 256 cases.

4429 Large cummulative patch for pic16 port.
4430 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4431 to call when a stack overflow occurs,
4432 * (malloc.h): added CVS Id tag,
4433 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4435 * added libc directory. The current version of LibC contains string
4436 functions, ctype functions and macros and some functions of the
4437 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4438 be extensively tested in the future. Standard disclaimer here.
4439 Library is not automatically build yet. But one can build it by
4440 invoking 'make' inside the libc directory.
4441 * added ADC library under libio. Preliminary version yet.
4443 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4450 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4451 * (pic16_storeForReturn): optimized return of 0,
4452 * (genCmp): experimental code for new genCmp which uses PIC18's
4453 special compare&skip instructions. Initial tests fail some times
4454 with variables grater than 1 byte in size, so new code is disabled,
4455 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4457 * (genCast): began a fix to optimize the casting of a bit to another
4458 bit, now assigning a bitfield to another bitfield will fail, sorry,
4459 * src/pic16/main.c: disabled the use of lr-support feature,
4460 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4461 * added some function prototypes, added function _debugf prototype,

4463 bits with offset (case PO_GPR_BIT),
4464 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4466 * (isBankInstruction): modified to return 0 for no banking instruction,
4467 and 1 for banking instruction,
4468 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4469 caused stop processing pCodes after a inline assembly block,
4470 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4471 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4472 registers when it shouldn't,
4473 * src/pic16/ralloc.c (allocReg): add preliminary support for
4474 supporting a limited set of temporary registers,
4476 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4478 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4479 genDataPointerSet): ensure assignments always copy in MSB to LSB
4481 (loadRegFromAop): recognize CLRH optimization,
4482 (genFunction): optimize RECEIVE iCodes in reentrant functions
4484 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4486 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4487 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

4500 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4502 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7436 code / RAM are in the same page / bank. This means the linker can
7437 safely allocate code/RAM of separate ASM files to different pages/banks.
7438 * doc/sdccman.lyx: added Slade's tips
7439 * src/mcs51/peeph.def: fixed bug #880768

7448 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
7451 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7452 strtof is not part of C89 and isn't included with Mac OS X.
7454 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7456 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,
7457 shiftL2Left2Result): fixed bug #879326
7458 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY

7481 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7483 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7484 loaded with the linker search paths (-L arguments) and the libraries
7485 to be linked with the current source (-l arguments). Changes
7486 currently will affect only the pic16 port.
7487 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7488 include path the port specific paths and port specific libraries,
7489 * gplink command now contains the $3 argument,
7490 * src/pic16/device.h,
7491 * src/pic16/device.c,: structure PIC_device is made public and
7492 renamed to PIC16_device, the same for variable Pics which is renamed
7493 to Pics16. Updated all references to them.
7494 * src/pic16/glue.c (pic16glue): corrected bug with code
7495 initialization which bypassed the variable initializations block.

7505 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7507 Documenting changes from previous commits.
7508 * configure.in (version 1.56),
7509 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7510 when generating output files to configure the pic16 library,
7511 but now I've commented it out, since gputils aren't installed in the
7512 SF compile farm, so library won't compile
7514 * device/lib/Makefile.in (version 1.56): initially I've added in
7515 target 'all' the prerequestive 'model-pic16' so it compiled the
7516 pic16 library, but now I've commented it out for the same reasons
7518 * added targets 'model-pic16' and 'objects-pic16' to compile the
7520 * added target 'port-specific-objects-pic16' to handle the
7521 generated libraries and copy them into the build/ directory
7522 * added target 'clean-intermediate-pic16' to clean intermediate
7523 files into pic16 directory
7524 * in target 'installdirs' added line to create directory pic16 in
7525 the installation path
7527 * device/include/Makefile.in (version 1.11): in target 'install'
7528 added lines to copy all header files to installation path,
7529 * in target 'installdirs' added line create directory for pic16
7530 headers in the installation path

7545 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7546 option so that it actually works. Made it specific to the z80, since
7547 the gbz80 doesn't have these kinds of I/O ports.
7549 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7551 * device/include/z180.h,

7564 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7566 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7567 changed interrupt vector table generation to only emit declared vectors.

7573 Mainly changes to support compilation of the device libraries
7574 * src/pic16/device.c: stack is allocated via symbol and not
7575 via literal number. The symbol is placed in the corresponding
7576 position of the data ram
7577 * (pic16_dump_section): relocatable and absolute uninitialized
7578 data are now emitted in sorted order to reduce section naming,
7579 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7580 weren't marked as being in the access bank,
7582 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7584 Added portion of GNU PIC Library under the directory
7585 device/include/pic16 and device/lib/pic16. These files
7586 contain the declarations of SFRs for the PIC18Fxx2 devices.
7587 The directory is initialized via configure from toplevel.
7589 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7591 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7592 the spilllocations to be compared correctly

7617 all over. Telling LaTeX to be less strict with word spacing
7618 to better keep the right margin. Changed some notes about
7619 maintainance of the ports in section 3.2.1 - is it OK like this?
7621 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7659 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7661 * src/pic16/peeph.def: all peepholes with movff are commented out,
7662 because there is a problem in the pcode peep optimizer,
7663 * src/pic16/ralloc.c: the register allocator can now reuse local

7728 directive when no overlay data exist
7729 * (picglue): modified to emit uninitialized data segment
7730 according to udata_section_name

7778 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7780 A python script to validate compiler diagnostic messages. It can be
7781 used to verify that sdcc complains about bad c source code and
7782 gives a good location of the error.
7783 * support/valdiag/Makefile,
7784 * support/valdiag/valdiag.py,
7785 * support/valdiag/tests/*

7802 Bug reported from Jesus Calvino-Fraga
7804 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7806 * sdcc.spec: updated
7807 * device/include/Makefile.in: don't install CVS directories

7811 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7812 * src/ds390/gen.c (genRightShift): fixed bug #870788
7813 * src/SDCCast.c (decorateType): fixed bug #870781
7815 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7817 PIC16 port related changes:
7818 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7819 added variable stackPos,
7821 * gen.c: genCall, assignResultValue: added support for
7822 pushing/retrieving function parameters to/from stack,
7823 genFunction,genEndFunction: setup stack frame for the
7825 genAddrOf: will be changed according to bug 863624
7827 * added files genutils.c and genutils.h which contain gen*
7828 debugged and optimised functions extracted from gen.c
7830 * glue.c: added variable 'externs' which holds extern symbols,
7831 pic16emitRegularMap: is modified to properly handle relocatable
7832 symbols under the new scheme,
7833 pic16createInterruptVect: is modified
7834 pic16printPublics: is modified to emit 'global' assembler directives,
7835 added pic16_printExterns to print extern symbols,
7836 pic16glue: initializes stack/frame pointer in the beginning of
7837 the assembly output. Temporary hack, will be corrected later,
7838 because gplink yet does not support stack and SDCC does not
7839 yet support a type of crt0.o object to create the final binary.
7841 * Removed many lines that contain 8051 legacy code.
7842 * The code is finally placed under a 'code' directive.
7843 * Added port specific options.
7845 * _process_pragma: simplified since now we do not need *special*
7846 include file to define SFR registers. But a separate header
7847 will be needed. This will be developed later.
7848 * _pic16_parseOptions: added, parses port specific options:
7849 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7850 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7851 --preplace-udata-with=
7853 * _pic16_setDefaultOptions: modified to initialize section names,
7854 but hack is temporarly out of order since it needs improvement.
7855 * _pic16_genAssemblerPreamble: configuration words are emitted by
7856 their address instead of their name. This part is incomplete and
7857 supports only the 18Fxx2 devices. Other devices will emit an error
7858 during assembly since they do not contain the same set of config
7860 * _pic16_genIVT: is modified,
7862 * pcode.c: added definitions for some hardware registers that are needed
7864 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7865 All PCI entries are updated. Now LFSR is supported.
7866 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7867 * added pic16_newpCodeOpLit2 to support instructions with
7868 two literal arguments
7869 * pic16_pCode2str: corrected code that emits assembler instructions
7870 with two literal operands and those that have an access bit modifier
7871 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7872 this fixes a bug which caused some labels to be lost, when an
7873 assembler directive was added, i.e. banksel,
7874 * pic16_FixRegisterBanking: improved logic that causes the insertion
7876 * InlineFunction: functions that are called once, are not any more
7877 inlined. This can be a port option in the future,
7879 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7881 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7882 hold the corresponding uninitialized symbols,
7883 * pic16_allocProcessorRegister: registers have explicit marked the
7885 * pic16_allocInternalRegister: registers are explicit marked as
7887 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7888 processing list, so bit registers were lost,
7891 * ralloc.h: added field 'accessBank' and original symbol operand
7892 in register definition,
7893 * removed the field isMapped from register definition,
7895 ** Several functions have been removed from various sources:
7896 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7897 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7898 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7899 pic16_assignRelocatableRegisters
7901 ** others have been introduced:
7902 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7903 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7905 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7907 * support/scripts/inc2h.pl: changed definition of BIT_AT
7908 to emit 'sbit at' instead of 'bit at'. This was a request.
7910 PIC16 port related preliminary changes:
7911 * gen.c: prefixed function popRegFromString with
7912 pic16_ and all references to it corrected
7913 * pcode.c: all pic16_pc_* hardware registers prefixed
7914 with underscore (_),
7915 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7916 * ralloc.c: newReg(): when register is REG_SFR then
7917 set address to rIdx,
7918 pic16_allocProcessorRegister(): marks register wasUsed=0
7919 pic16_writeUsedRegs(): added a call to assign processor
7920 registers via pic16_assignFixedRegisters
7922 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7924 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7925 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7926 variables in unused register banks. Also the SSEG is placed
7927 wherever there is enough space for it, and IDATA can be anywhere
7928 in internal RAM. For now compile using -Wl-Y[stack_size].
7929 The mem file is different for this option as well, since it
7930 makes no sense of talking about DSEG lenght.

8918 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
8920 * device/lib/_mullong.c: replaced int by short for gcc
8922 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8924 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
8925 and JUMPTABLE iCodes properly now (worked by accident before)
8926 * src/mcs51/gen.c (leftRightUseAcc),
8927 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
8928 iCode properly now. Use getSize instead of nRegs since a & b
8929 aren't part of the nRegs tally.
8931 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
8933 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
8934 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive

8939 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8940 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8941 fetching of the pointer
8942 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8943 copied from genNearPointerSet()
8944 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8945 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8946 If they pop r0/r1 they must be called in the opposite order than aopOp().
8947 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8948 (resp. --stack-auto), prepared for --xstack

8954 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8956 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
8957 these ports have their own __sdcc_external_start()
8959 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8961 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8962 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8963 type for bits was changed. It resulted in bit variables becoming
8964 global, which is not permitted in PIC 14 assembly output.
8966 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8968 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8981 A few small changes that speed up the peephole optimizer.
8985 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8987 Try to make the peephole optimizer smarter by maintaining
8988 an association between the assembly source code and the
8989 iCodes that originated them. Put this information to use
8990 with a new peephole rule condition "notVolatile" so that
8991 the rules can be aggressive yet still safe.
8996 * src/mcs51/peeph.def
8998 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9002 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9003 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9004 if the left or right operand symbols have the accuse flag set.
9006 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9008 Changed the type of the result of the ! (NOT) operator to char;
9009 previously it returned the same type as the source. This allows
9010 us to eliminate all the genFloatNot functions (all of its target
9011 implementations were very buggy) since !float can use the same
9014 * src/SDCCicode.c (ast2iCode): ! returns char
9015 * src/mcs51/gen.c (genNot, genNotFloat),
9016 * src/ds390/gen.c (genNot, genNotFloat),
9017 * src/z80/gen.c (genNot, genNotFloat),
9018 * src/pic/gen.c (genNot, genNotFloat),
9019 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

9023 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9024 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9025 during interrupts. Ensure WSAVE is located at a shared bank address.
9026 2. Fixed page selection in some places
9027 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9028 the registers name strings.
9029 4. Fixed "signed / unsigned compare" compiler warnings.
9030 5. The PIC port manages its own allocation of the general purpose
9031 registers, but makes no attempt to reuse them. As a result when
9032 compiling it soon runs out of general purpose registers. Some
9033 additional code was added to the files pcode.c and device.c to walk
9034 through the function call tree and rename the registers so that they
9044 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9045 genPlus() & genMinus() when the result is the same as left or right

9051 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9053 Made bitfield a distinct type from bit so that bitfields
9054 convert as per ANSI C and bits retain their traditional
9055 boolean style behaviour. Implemented bitfield support in
9063 * src/ds390/gen.c: bit v bitfield split
9064 * src/z80/gen.c: New support for bitfields
9065 * support/regression/tests/bitfields.c: reenabled z80,
9068 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9070 Rules 246.x, 247.x relate to bitfields, the others speed up
9071 access to xdata mapped I/O devices.
9073 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9075 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9077 Cleaned up genPackBits and genUnpackBits and added two helper
9078 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9079 for literal assignments in genPackBits (thanks to Frieder for
9085 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9087 Fixed bug #748310 (pointer to function type mishandled when the
9088 function name is omitted). Also fixed a SIGSEGV when a function
9089 attribute (reentrant, etc) is used on a non-function or on a
9090 function but misplaced before the parameter list.
9092 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9094 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9095 * support/Util/SDCCerr.h,
9096 * support/Util/SDCCerr.c: Added func attr misuse error msg

9117 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9119 Made the constant following the "interrupt" keyword optional. If
9120 omitted, the function will not automatically be given an entry
9121 in the interrupt vector table (similar to #pragma NOIV, but
9122 less syntacticly kludgy). The interrupt number is also now
9123 range checked. Also fixed a bug in the high order bit example
9130 * support/Util/SDCCerr.c
9131 * support/Util/SDCCerr.h
9134 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9139 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9141 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9142 be re-activated by defining REDUCE_LITERALS)
9143 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9144 unsigned, but are signed by default
9145 * src/SDCCval.c (constVal): rearranged
9146 * src/SDCCval.c (valMod): preliminary fix
9147 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9599 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9600 the regression tests I'm not brave enough to enable 245.b, 245.c
9601 * doc/sdccman.lyx: added latex preamble for hyperref package.
9602 Using pdflatex this will give you a hyperlinked pdf file with
9603 bookmarks. (prepend '%' before /usepackage if this breaks something)

9641 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9643 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9644 it can be defined with CFLAGS when running configure
9645 * src/SDCCmain.c: fixed compiling + linking with object files
9647 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9650 added --disable-pic16-port
9651 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9652 * src/SDCCmain.c: linkOptions is changed to set *,
9653 added if/endif conditional macros to remove options help
9654 messages from optionsTable when a port is not configured, added
9655 support for the PIc16 port in the ports table, when executing
9656 the compiler with no port specified on command line, a default
9657 port is selected with the new macro DEFAULT_PORT which is
9658 defined in port.h, in setDefaultOptions() linkOptions is removed
9659 from initialization assignment, since now it is a set,
9660 parseCmdLine uses setParseWithComma for linkOptions, in
9661 linkEdit() linkOptions are accessed with new function indexSet()
9662 which returns the i'th item of a set variable. See SDCCset.c, in
9663 linkEdit() when calling buildCmdLine(), added linkOptions as
9664 last argument. Now users can pass arguments to gplink via the
9665 -Wl option, main() uses pic16glue() to glue up pic16 programs

9675 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
9677 * src/pic16/glue.c: commented out some error producing lines
9678 * src/pic16/main.c: __config directives are commented out to stop
9679 gpasm complaining and test the linkage with gplink, _linkCmd and
9680 _asmCmd changed to be more gplink and gpasm friendly
9681 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9682 produced an error when parsed, peep rule 12 is added to utilize
9683 movff, but it is commented out since the pCode does not support
9684 yet a command with 2 address arguments
9686 2003-05-18 <johan AT balder>
9688 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9715 2003-05-11 Borut Razem <borut.razem AT siol.net>
9717 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9718 the path of bin directory, so that PATH is the only env. variable, which has to be set
9719 in case of standard installation.

10805 size. If the space for the stack is less than 16 bytes aslink trows a
10808 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10809 the 8051. Option 'y' for memory summary output file.
10811 Changes to sdcc (All the changes are marked with 'JCF'):
10813 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10815 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10816 overlaying area for it (uses RegBankUsed[4]).
10818 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10819 bank zero as used by default. By default aslink locates the stack
10820 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10821 the creation of the .mem file. Delegates the allocation of data area
10822 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10823 the begining of the stack area to aslink.
10825 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10826 glue() in SDCCglue.c creates an area for it.
10828 2002-09-03 Borut Razem <borut.razem AT siol.net>
10829 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10830 sdcc/src/pic/glue.c:
10831 introduced atexit() handler for teporay files removal in case of
10832 errors, assertions, ...
10834 2002-08-29 Borut Razem <borut.razem AT siol.net>
10835 * sdcc/support/cpp2/auto-host_vc_in.h:
10836 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10837 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10838 Maybe there is a similar problem with BORLANDC? It should be checked!
10840 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10841 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10842 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10843 was not executed, and the compiler (cl) launched a warning:
10844 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10846 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10847 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10849 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10850 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10852 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10853 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10854 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10855 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10856 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10857 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10858 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10859 - added Release configuration in VS projects
10860 - review of compiler an linker options
10861 - VC .exe files are generated in bin_vc directory, not to interfere
10862 with binaries generated from other projects (cygwin, mingw, bcc ...)
10864 * sdcc/src/yacc.dsp: added
10866 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10867 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10868 and insert the version number definitions from .version
10870 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10872 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10873 added - genarate auto-host.h using auto-host_vc_in.h as template
10876 removed from CVS, generated automatically
10878 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10879 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10881 2002-08-11 Borut Razem <borut.razem AT siol.net>
10882 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10884 2002-08-10 Borut Razem <borut.razem AT siol.net>
10885 * src/SDCCmain.c (main):
10886 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10887 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10888 The consequence was that some temporary files were not removed.
10891 unification of code in functions tempfilename() and tempfile():
10892 function tempnam() is defined in Visual Studio 6.0 and .NET
10894 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10896 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10897 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10898 - removed compiler command line option /WX: Treats all warnings as errors
10899 - update a list of source files, included into the project
10901 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10902 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10903 changed project type to Generic Project so that can be correcly converted to VS.NET project
10905 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10907 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10909 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10911 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10912 added return 0 statements after assert() to make compiler happy
10914 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10915 added newline in the def file to keep MSC compiler satisfied
10917 * sdcc/src/z80/gen.c:
10918 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10919 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10920 - solved MSC error in function aopDump()
10922 * sdcc_vc.h: define PREFIX as "\\sdcc"
10924 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10925 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10973 Added -p option. Allows port dependent processor to be specified.
10976 Initialized the new field char *Processor field to NULL in all ports
10979 Compiler generated registers for interrupt context saving
10980 were not getting allocated.
10982 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10985 Fixed left shift. Will promote the left side of a left shift
10986 if a) left shifting more than size of operand or b) when assigned
10987 to something size > size of left side

11097 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11099 * sdcc/src/SDCCloop.c:
11100 Previous fix was not good. basic blocks that have "break" or "return" are
11101 not really partof a loop , but live ranges used in these blocks should
11102 be live thru the entire loop, so set partOfLoop but don't add them to
11105 2002-02-21 <johan AT FRIJA>
11107 * src/SDCCcse.c: fixed bug #514308
11109 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
