789 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
791 Enabled VPATH feature: changed nearly all Makefiles (149 files).
792 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
794 One basic decision: e.g. src/clean.mk includes further files. In order
795 to make this work there are two solutions:
796 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
797 run configure on them. This way they can use
798 'include $(srcdir)/port-clean.mk'
799 - always include clean.mk by the Makefile at the same level. To avoid
800 that `make clean` tries to include and build Makefile.dep the
801 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
802 implemented, because now even `make uninstall` doesn't create
803 Makefile.in. clean.mk could be eliminated by pasting it in
806 * debugger/mcs51/Makefile.in: build own objects from library sources
807 (SLIB, SDCC) in current directory
809 * configure, configure.in: renamed --disable-device-lib-build in
810 --disable-device-lib; added --enable-doc, the required tools are
811 searched by configure; added result message; the toolchain for the
812 belonging ports are now only built, if the port is enabled.
814 * support/regression/*: all output is written in directory gen, because
815 the fwk and ports directories don't livet in the build tree using vpath
817 * doc/sdccman.lyx: renamed --disable-device-lib-build to
818 --disable-device-lib, added --enable-doc, added section VPATH
820 * sim/ucsim/configure.in,
821 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
822 z80 are enabled by default
824 2006-04-24 Raphael Neider <rneider AT web.de>
826 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
827 to config word, "pic14_"-prefixed some extern functions
828 (pic14_emitConfigWord): emit __config directive(s) if assignment to
829 config word has been found
830 * src/pic/device.h: added prototypes
831 * src/pic/pcode.c: added "pic14_"-prefix where needed

834 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

837 (pic14createInterruptVect): moved generating __config directives away

1095 implemented patch 1120823 Thanks to Willy De la Court (normal
1096 interrupts need an interrupt number now if they are made critical),
1097 and enabled nesting of critical functions though not for gbz80
1098 (genCritical, genEndCritical): added functions
1099 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1100 * src/z80/mappings.i: added "ei" to all mappings

1112 the left operand is shorter than the result (c* = lit-c* + int),
1114 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1117 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1119 * src/.version: increased version number to 2.5.5
1120 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1121 linking is done manually in pic16 port's _linkEdit,
1122 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1123 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1124 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1125 allocate asmop as AOP_ACC,
1126 (aopForRemat): added parameter 'bool result' in function declaration,
1127 (pic16_aopGet): return AOP_ACC when accessing WREG,
1128 (pic16_popGetTempReg): minor modification,

1139 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1140 call to allocReg, not by manually allocating a new one,
1141 (pic16_assignRegisters): now before going through the register
1142 allocating functions mark all registers as free. This eliminates some
1143 side effects resulting from peephole parser done earlier in the backbone
1145 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1203 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1204 which dumps before the function entry point a data byte which represents
1205 the number of the local variables used by the specified function, added
1206 'xinst' for initial support for Extended Instruction Support,
1207 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1208 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1209 port->fun_prefix anymore (may change later),
1210 (genFunction, genEndFunction): do not store/restore local registers for
1211 _main (this should take care the --main-return command line option in
1213 (genOr): removed some legacy pic-port instructions,
1214 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1215 performing operations with SFR's causes data to be written more than
1216 once to each SFR. Perhaps SFRs should be handled in special cases...
1217 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1219 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1220 into account for stack starting position,
1221 (struct OPTIONS pic16_optionsTable): added command line argument
1222 --extended or -y for Extended Instruction Support,
1223 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1224 (deassignLRs): *** perhaps the most important change, old 'for' code
1225 (commented out for reference), didn't account for some registers which
1226 were left marked 'not free' after a pointer operation. The change
1227 reduces register usage a lot in some cases
1229 2006-03-04 Borut Razem <borut.razem AT siol.net>

3478 where not placed in the same memory bank,
3479 * device/lib/pic16/libsdcc/char/: various modifications to improve
3480 library performance,

3491 if condition == CARRY)
3492 * (genCmp): adapted to new genSkipc semantics
3493 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
3494 on rIfx (genCmp was broken)
3496 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3498 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3499 * src/z80/main.c (_keywords[]),
3500 * src/SDCCglobal.h (struct options),
3502 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3503 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3504 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3505 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3506 always available in leading double underscore form. The C99 support is
3507 mostly missing, but it's a start.
3508 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3509 reserved identifier "__data".
3511 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3513 * src/mcs51/peeph.def: fixed bug 1170013

3524 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3526 * src/port.h (struct PORT),

3555 immedDom() returning wrong block; probably fixes bug #1160833)
3557 2005-03-20 Borut Razem <borut.razem AT siol.net>
3559 * support/scripts/inc2h.pl: WIN32 port
3561 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3563 * device/lib/makefile.in: added abs.c and labs.c
3565 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3567 * device/include/stdint.h: added
3568 * device/lib/abs.c: added
3569 * device/lib/labs.c: added
3570 * device/include/stdlib.h: added abs() and labs() prototypes

3587 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3589 * device/lib/printf_large.c: removed inline assembly for portability and
3590 readability. Use printf_fast if speed or size are more important.
3591 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3592 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3594 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3596 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3597 prevent compiler warning
3599 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3601 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3602 moved to level 0 and declared as static. Also they are explicit
3603 placed in access bank. This was necessery because some times they
3604 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3605 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3606 optimizations. Currently only compare to unsigned char is implemented,
3607 * src/pic16/gen.c: added fReturnIdx array,
3608 * (struct resolvedIfx) is moved to gen.h and made public,
3609 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3610 * (aopForSym): added an optimization to directly store in stack of
3611 the operand of a SEND iCode,
3612 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3613 but as registers instead (AOP_REG) using the fReturnIdx array,
3614 * (pic16_freeAsmop): remove the freed register from the
3615 _G.sregsAlloc field,
3616 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3617 a compare of 'WREG',
3618 * (pic16_popGetTempRegCond): changed function prototype, now
3619 function takes also a bitVector argument v which holds the current
3620 set of registers that are allocated for stack access by aopForSym,
3621 registers allocated in aopForSym for accessing stack symbols are not
3622 any more part of the functions usedRegs field,
3623 * (genCall): some times aopOp is called for a stack variable to be
3624 send, aopForSym might perform the push, if this is true make sure
3625 that genCall doesn't push the variable twice by testing _G.resDirect,
3626 * (genFunction): changed testing for unspecified interrupt number
3627 from 256 to INTNO_UNSPEC,
3628 * modified selection scheme of frame pointer generation. Previously
3629 if function did use local registers a frame pointer was generated,
3630 now a frame pointer is generated only if function has arguments
3631 (that need PLUSW2 register access), or has stack arguments, or the
3632 compiler is not instructed to omit the frame pointer,
3633 * (genEndFunction): before restoring local registers that were saved
3634 in the function preamble, also restore the registers that *might*
3635 have been allocated for stack access,
3636 * (genRet): removed some old comments,
3637 * (genCmp, the active (RN's) version): added a call to the
3638 pic16_genCmp_special function to perform the compare with a more
3639 robust and optimized way,
3640 * (genInline): a feature has been added in inline code generation,
3641 which allows a wildcard variable substitution when writing inline
3642 assembly. Code is incomplete and experimental therefore undocumented,
3643 * (genCast): changed order of aopOp for result and right to allow
3644 aopForSym to directly load the result if possible,
3645 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3646 perform an optimized compare on some selected special occasions,
3647 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3648 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3649 generate an IVT any more,
3650 * src/pic16/main.c (pic16_optionsTable): added command line option
3652 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3653 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3655 * src/pic16/NOTES: Raphael Neider added in list of active developers
3656 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3657 jumptable_end to prevent bug #,
3658 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3659 inCond and outCond fields,
3660 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3661 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3662 turn off register spilling,
3663 * (packRegsForOneUse): synced with other ports' versions although it
3664 is not used currently,
3665 * (pic16_packRegisters): added an optimization while reading
3666 structure bitfields, some registers may be saved (malloc code is
3667 decreased by 80 bytes)
3669 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3671 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3672 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3673 this can be optimized more?
3675 2005-03-10 Raphael Neider <rneider AT web.de>
3677 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3678 genNearPointerGet): (hopefully) fixed access to bitfields via
3679 pointers (p->bitN = x; and x = p->bitN; failed)
3681 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3867 of (byte sized) temporaries (assign them to WREG for now)
3868 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3869 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3870 this might fix SIGSEGVs on MinGW...
3871 * src/SDCCopt.c (killDeadCode): restored original behaviour
3872 (volatile operands might get thrown away though)
3874 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
3876 * src/pic16/gen.c: fixed bug #1106975,

4343 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
4345 Large cummulative patch for pic16 port.
4346 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4347 to call when a stack overflow occurs,
4348 * (malloc.h): added CVS Id tag,
4349 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4351 * added libc directory. The current version of LibC contains string
4352 functions, ctype functions and macros and some functions of the
4353 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4354 be extensively tested in the future. Standard disclaimer here.
4355 Library is not automatically build yet. But one can build it by
4356 invoking 'make' inside the libc directory.
4357 * added ADC library under libio. Preliminary version yet.
4359 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
4360 * src/pic16/gen.c (aopForRemat): asmop size is filled by
4361 aopForRemat() now and not by pic16_aopOp(),
4362 * (pic16_popGetTempReg): removed warning messgae when allocating
4363 temporary registers, its a buggy feature and will be removed,
4364 * (pic16_popGet): set register instance field in AOP_CRY,
4365 * (pic16_outBitC): fixed for results in size greater than 1,
4366 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4367 * (pic16_storeForReturn): optimized return of 0,
4368 * (genCmp): experimental code for new genCmp which uses PIC18's
4369 special compare&skip instructions. Initial tests fail some times
4370 with variables grater than 1 byte in size, so new code is disabled,
4371 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4373 * (genCast): began a fix to optimize the casting of a bit to another
4374 bit, now assigning a bitfield to another bitfield will fail, sorry,
4375 * src/pic16/main.c: disabled the use of lr-support feature,
4376 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4377 * added some function prototypes, added function _debugf prototype,
4378 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
4379 bits with offset (case PO_GPR_BIT),
4380 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4382 * (isBankInstruction): modified to return 0 for no banking instruction,
4383 and 1 for banking instruction,
4384 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4385 caused stop processing pCodes after a inline assembly block,
4386 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4387 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4388 registers when it shouldn't,
4389 * src/pic16/ralloc.c (allocReg): add preliminary support for
4390 supporting a limited set of temporary registers,
4392 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4394 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4395 genDataPointerSet): ensure assignments always copy in MSB to LSB
4397 (loadRegFromAop): recognize CLRH optimization,
4398 (genFunction): optimize RECEIVE iCodes in reentrant functions
4400 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4402 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4403 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4405 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
4406 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
4407 contiguous with data

4411 * device/lib/_gptrget.c (_gptrget),
4412 * device/lib/_gptrgetc.c (_gptrgetc),
4413 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
4414 instead of sjmp to ret
4415 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
4416 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4418 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7397 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7399 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7400 loaded with the linker search paths (-L arguments) and the libraries
7401 to be linked with the current source (-l arguments). Changes
7402 currently will affect only the pic16 port.
7403 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7404 include path the port specific paths and port specific libraries,
7405 * gplink command now contains the $3 argument,
7406 * src/pic16/device.h,
7407 * src/pic16/device.c,: structure PIC_device is made public and
7408 renamed to PIC16_device, the same for variable Pics which is renamed

7423 Documenting changes from previous commits.
7424 * configure.in (version 1.56),
7425 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7426 when generating output files to configure the pic16 library,
7427 but now I've commented it out, since gputils aren't installed in the
7428 SF compile farm, so library won't compile
7430 * device/lib/Makefile.in (version 1.56): initially I've added in
7431 target 'all' the prerequestive 'model-pic16' so it compiled the
7432 pic16 library, but now I've commented it out for the same reasons
7434 * added targets 'model-pic16' and 'objects-pic16' to compile the
7436 * added target 'port-specific-objects-pic16' to handle the
7437 generated libraries and copy them into the build/ directory
7438 * added target 'clean-intermediate-pic16' to clean intermediate
7439 files into pic16 directory
7440 * in target 'installdirs' added line to create directory pic16 in

7491 via literal number. The symbol is placed in the corresponding
7492 position of the data ram
7493 * (pic16_dump_section): relocatable and absolute uninitialized
7494 data are now emitted in sorted order to reduce section naming,
7495 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7496 weren't marked as being in the access bank,
7498 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7500 Added portion of GNU PIC Library under the directory
7501 device/include/pic16 and device/lib/pic16. These files
7502 contain the declarations of SFRs for the PIC18Fxx2 devices.
7503 The directory is initialized via configure from toplevel.
7505 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7507 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

7533 all over. Telling LaTeX to be less strict with word spacing
7534 to better keep the right margin. Changed some notes about
7535 maintainance of the ports in section 3.2.1 - is it OK like this?
7537 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7577 * src/pic16/peeph.def: all peepholes with movff are commented out,
7578 because there is a problem in the pcode peep optimizer,
7579 * src/pic16/ralloc.c: the register allocator can now reuse local

7656 2004-01-07 Borut Razem <borut.razem AT siol.net>
7658 * support/scripts/sdcc.nsi: update PATH
7659 * support/scripts/sdcc.ico: craeted

7672 include information about variables allocated to the overlay
7675 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7677 * as/mcs51/lkmain.c: Help about -Y option

7689 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7691 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7692 (default behaviour).
7694 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7696 A python script to validate compiler diagnostic messages. It can be
7697 used to verify that sdcc complains about bad c source code and
7698 gives a good location of the error.
7699 * support/valdiag/Makefile,
7700 * support/valdiag/valdiag.py,
7701 * support/valdiag/tests/*
7703 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7705 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

7716 * src/common.h: added ifndef/define/endif macros
7717 around the header file.
7718 Bug reported from Jesus Calvino-Fraga
7720 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7722 * sdcc.spec: updated
7723 * device/include/Makefile.in: don't install CVS directories
7724 * device/lib/Makefile.in: added removal of CVS directories after install
7725 * doc/Makefile: fixed install, added local_icons
7726 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7727 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7728 * src/ds390/gen.c (genRightShift): fixed bug #870788
7729 * src/SDCCast.c (decorateType): fixed bug #870781
7731 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7733 PIC16 port related changes:
7734 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7735 added variable stackPos,
7737 * gen.c: genCall, assignResultValue: added support for
7738 pushing/retrieving function parameters to/from stack,
7739 genFunction,genEndFunction: setup stack frame for the
7741 genAddrOf: will be changed according to bug 863624
7743 * added files genutils.c and genutils.h which contain gen*
7744 debugged and optimised functions extracted from gen.c
7746 * glue.c: added variable 'externs' which holds extern symbols,
7747 pic16emitRegularMap: is modified to properly handle relocatable
7748 symbols under the new scheme,
7749 pic16createInterruptVect: is modified
7750 pic16printPublics: is modified to emit 'global' assembler directives,
7751 added pic16_printExterns to print extern symbols,
7752 pic16glue: initializes stack/frame pointer in the beginning of
7753 the assembly output. Temporary hack, will be corrected later,
7754 because gplink yet does not support stack and SDCC does not
7755 yet support a type of crt0.o object to create the final binary.
7757 * Removed many lines that contain 8051 legacy code.
7758 * The code is finally placed under a 'code' directive.
7759 * Added port specific options.
7761 * _process_pragma: simplified since now we do not need *special*
7762 include file to define SFR registers. But a separate header
7763 will be needed. This will be developed later.
7764 * _pic16_parseOptions: added, parses port specific options:
7765 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7766 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7767 --preplace-udata-with=
7769 * _pic16_setDefaultOptions: modified to initialize section names,
7770 but hack is temporarly out of order since it needs improvement.
7771 * _pic16_genAssemblerPreamble: configuration words are emitted by
7772 their address instead of their name. This part is incomplete and
7773 supports only the 18Fxx2 devices. Other devices will emit an error
7774 during assembly since they do not contain the same set of config
7776 * _pic16_genIVT: is modified,
7778 * pcode.c: added definitions for some hardware registers that are needed
7780 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7781 All PCI entries are updated. Now LFSR is supported.
7782 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7783 * added pic16_newpCodeOpLit2 to support instructions with
7784 two literal arguments
7785 * pic16_pCode2str: corrected code that emits assembler instructions
7786 with two literal operands and those that have an access bit modifier
7787 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7788 this fixes a bug which caused some labels to be lost, when an
7789 assembler directive was added, i.e. banksel,
7790 * pic16_FixRegisterBanking: improved logic that causes the insertion
7792 * InlineFunction: functions that are called once, are not any more
7793 inlined. This can be a port option in the future,
7795 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7797 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7798 hold the corresponding uninitialized symbols,
7799 * pic16_allocProcessorRegister: registers have explicit marked the
7801 * pic16_allocInternalRegister: registers are explicit marked as
7803 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7804 processing list, so bit registers were lost,
7807 * ralloc.h: added field 'accessBank' and original symbol operand
7808 in register definition,
7809 * removed the field isMapped from register definition,
7811 ** Several functions have been removed from various sources:
7812 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7813 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7814 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7815 pic16_assignRelocatableRegisters
7817 ** others have been introduced:
7818 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7819 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7821 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7823 * support/scripts/inc2h.pl: changed definition of BIT_AT
7824 to emit 'sbit at' instead of 'bit at'. This was a request.
7826 PIC16 port related preliminary changes:
7827 * gen.c: prefixed function popRegFromString with
7828 pic16_ and all references to it corrected
7829 * pcode.c: all pic16_pc_* hardware registers prefixed
7830 with underscore (_),
7831 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7832 * ralloc.c: newReg(): when register is REG_SFR then
7833 set address to rIdx,
7834 pic16_allocProcessorRegister(): marks register wasUsed=0
7835 pic16_writeUsedRegs(): added a call to assign processor
7836 registers via pic16_assignFixedRegisters
7838 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7840 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7841 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7842 variables in unused register banks. Also the SSEG is placed
7843 wherever there is enough space for it, and IDATA can be anywhere
7844 in internal RAM. For now compile using -Wl-Y[stack_size].
7845 The mem file is different for this option as well, since it
7846 makes no sense of talking about DSEG lenght.
7848 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7850 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7851 in certain cases, e.g. when ROM assignment, patch provided
7852 from Albert den Haan.
7854 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8877 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8878 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

8895 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8897 A few small changes that speed up the peephole optimizer.
8901 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8903 Try to make the peephole optimizer smarter by maintaining
8904 an association between the assembly source code and the
8905 iCodes that originated them. Put this information to use
8906 with a new peephole rule condition "notVolatile" so that
8907 the rules can be aggressive yet still safe.
8912 * src/mcs51/peeph.def
8914 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8918 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

8920 if the left or right operand symbols have the accuse flag set.
8922 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8924 Changed the type of the result of the ! (NOT) operator to char;
8925 previously it returned the same type as the source. This allows
8926 us to eliminate all the genFloatNot functions (all of its target
8927 implementations were very buggy) since !float can use the same
8930 * src/SDCCicode.c (ast2iCode): ! returns char
8931 * src/mcs51/gen.c (genNot, genNotFloat),
8932 * src/ds390/gen.c (genNot, genNotFloat),
8933 * src/z80/gen.c (genNot, genNotFloat),
8934 * src/pic/gen.c (genNot, genNotFloat),

8939 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8940 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8941 during interrupts. Ensure WSAVE is located at a shared bank address.
8942 2. Fixed page selection in some places
8943 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8944 the registers name strings.
8945 4. Fixed "signed / unsigned compare" compiler warnings.
8946 5. The PIC port manages its own allocation of the general purpose
8947 registers, but makes no attempt to reuse them. As a result when
8948 compiling it soon runs out of general purpose registers. Some
8949 additional code was added to the files pcode.c and device.c to walk
8950 through the function call tree and rename the registers so that they
8960 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8967 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8969 Made bitfield a distinct type from bit so that bitfields
8970 convert as per ANSI C and bits retain their traditional
8971 boolean style behaviour. Implemented bitfield support in
8979 * src/ds390/gen.c: bit v bitfield split
8980 * src/z80/gen.c: New support for bitfields
8981 * support/regression/tests/bitfields.c: reenabled z80,
8984 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8986 Rules 246.x, 247.x relate to bitfields, the others speed up
8987 access to xdata mapped I/O devices.
8989 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8991 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8993 Cleaned up genPackBits and genUnpackBits and added two helper
8994 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8995 for literal assignments in genPackBits (thanks to Frieder for
9001 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9003 Fixed bug #748310 (pointer to function type mishandled when the
9004 function name is omitted). Also fixed a SIGSEGV when a function
9005 attribute (reentrant, etc) is used on a non-function or on a
9006 function but misplaced before the parameter list.

9033 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9035 Made the constant following the "interrupt" keyword optional. If
9036 omitted, the function will not automatically be given an entry
9037 in the interrupt vector table (similar to #pragma NOIV, but
9038 less syntacticly kludgy). The interrupt number is also now
9039 range checked. Also fixed a bug in the high order bit example

9560 it can be defined with CFLAGS when running configure
9561 * src/SDCCmain.c: fixed compiling + linking with object files
9563 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9566 added --disable-pic16-port
9567 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9568 * src/SDCCmain.c: linkOptions is changed to set *,
9569 added if/endif conditional macros to remove options help
9570 messages from optionsTable when a port is not configured, added
9571 support for the PIc16 port in the ports table, when executing
9572 the compiler with no port specified on command line, a default
9573 port is selected with the new macro DEFAULT_PORT which is
9574 defined in port.h, in setDefaultOptions() linkOptions is removed
9575 from initialization assignment, since now it is a set,
9576 parseCmdLine uses setParseWithComma for linkOptions, in
9577 linkEdit() linkOptions are accessed with new function indexSet()
9578 which returns the i'th item of a set variable. See SDCCset.c, in
9579 linkEdit() when calling buildCmdLine(), added linkOptions as
9580 last argument. Now users can pass arguments to gplink via the
9581 -Wl option, main() uses pic16glue() to glue up pic16 programs

9593 * src/pic16/glue.c: commented out some error producing lines
9594 * src/pic16/main.c: __config directives are commented out to stop
9595 gpasm complaining and test the linkage with gplink, _linkCmd and
9596 _asmCmd changed to be more gplink and gpasm friendly
9597 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9598 produced an error when parsed, peep rule 12 is added to utilize
9599 movff, but it is commented out since the pCode does not support
9600 yet a command with 2 address arguments
9602 2003-05-18 <johan AT balder>
9604 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9631 2003-05-11 Borut Razem <borut.razem AT siol.net>
9633 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10665 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10667 * in \sdcc\as\mcs51\ changed these files in order to create an
10668 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10669 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10670 following files to include the previous two files: aslink.dsp,
10671 Makefile.aslink, Makefile.bcc, and Makefile.in.
10673 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10674 .adb instead of .cdb
10676 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10678 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10679 value from option --iram-size.
10681 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10683 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10686 2002-09-18 <wiml AT hhhh.org>
10688 * SDCClrange.h: exposed setFromRange() and setToRange()
10689 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10690 packRegsForAccUse() (bug 542397)
10691 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10692 multiple times and emitting the fetch operations more than once
10693 added aopGetUsesAcc() function to allow binary operators to
10694 fetch their operands in the correct order; made genMinus() emit
10695 compact code for X = LITERAL - Y
10697 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10698 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10699 sprintf() in line 1267.
10701 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10702 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10705 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10706 Changes to aslink (All the changes are marked with 'JCF'):
10708 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10711 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10712 area BSEG. Also moves, if possible, the DATA area down into the internal
10713 ram so more space is available.
10715 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10718 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10719 not bytes. Function summary() which creates a memory usage summary
10720 file with extension .mem. Reports of overlaping stack and small stack
10721 size. If the space for the stack is less than 16 bytes aslink trows a
10724 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10725 the 8051. Option 'y' for memory summary output file.
10727 Changes to sdcc (All the changes are marked with 'JCF'):
10729 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10731 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10732 overlaying area for it (uses RegBankUsed[4]).
10734 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10735 bank zero as used by default. By default aslink locates the stack
10736 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10737 the creation of the .mem file. Delegates the allocation of data area
10738 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10739 the begining of the stack area to aslink.
10741 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10742 glue() in SDCCglue.c creates an area for it.
10744 2002-09-03 Borut Razem <borut.razem AT siol.net>
10745 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10746 sdcc/src/pic/glue.c:
10747 introduced atexit() handler for teporay files removal in case of
10748 errors, assertions, ...
10750 2002-08-29 Borut Razem <borut.razem AT siol.net>
10751 * sdcc/support/cpp2/auto-host_vc_in.h:
10752 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10753 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10754 Maybe there is a similar problem with BORLANDC? It should be checked!
10756 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10757 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10758 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10759 was not executed, and the compiler (cl) launched a warning:
10760 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10762 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10763 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

10777 - VC .exe files are generated in bin_vc directory, not to interfere
10778 with binaries generated from other projects (cygwin, mingw, bcc ...)
10780 * sdcc/src/yacc.dsp: added
10782 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:

10792 removed from CVS, generated automatically
10794 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10795 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10797 2002-08-11 Borut Razem <borut.razem AT siol.net>
10798 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)

10801 * src/SDCCmain.c (main):
10802 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10803 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10804 The consequence was that some temporary files were not removed.
10807 unification of code in functions tempfilename() and tempfile():
10808 function tempnam() is defined in Visual Studio 6.0 and .NET
10810 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10812 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10813 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10814 - removed compiler command line option /WX: Treats all warnings as errors
10815 - update a list of source files, included into the project
10817 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10818 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10819 changed project type to Generic Project so that can be correcly converted to VS.NET project
10821 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10823 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10825 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10827 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10828 added return 0 statements after assert() to make compiler happy
10830 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10831 added newline in the def file to keep MSC compiler satisfied
10833 * sdcc/src/z80/gen.c:
10834 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10835 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10836 - solved MSC error in function aopDump()
10838 * sdcc_vc.h: define PREFIX as "\\sdcc"

11015 * sdcc/src/SDCCloop.c:
11016 Previous fix was not good. basic blocks that have "break" or "return" are
11017 not really partof a loop , but live ranges used in these blocks should
