817 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
819 Enabled VPATH feature: changed nearly all Makefiles (149 files).
820 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
822 One basic decision: e.g. src/clean.mk includes further files. In order
823 to make this work there are two solutions:
824 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
825 run configure on them. This way they can use
826 'include $(srcdir)/port-clean.mk'
827 - always include clean.mk by the Makefile at the same level. To avoid
828 that `make clean` tries to include and build Makefile.dep the
829 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
830 implemented, because now even `make uninstall` doesn't create
831 Makefile.in. clean.mk could be eliminated by pasting it in
834 * debugger/mcs51/Makefile.in: build own objects from library sources
835 (SLIB, SDCC) in current directory
837 * configure, configure.in: renamed --disable-device-lib-build in
838 --disable-device-lib; added --enable-doc, the required tools are
839 searched by configure; added result message; the toolchain for the
840 belonging ports are now only built, if the port is enabled.
842 * support/regression/*: all output is written in directory gen, because
843 the fwk and ports directories don't livet in the build tree using vpath
845 * doc/sdccman.lyx: renamed --disable-device-lib-build to
846 --disable-device-lib, added --enable-doc, added section VPATH
848 * sim/ucsim/configure.in,
849 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
850 z80 are enabled by default
852 2006-04-24 Raphael Neider <rneider AT web.de>
854 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
855 to config word, "pic14_"-prefixed some extern functions
856 (pic14_emitConfigWord): emit __config directive(s) if assignment to
857 config word has been found
858 * src/pic/device.h: added prototypes
859 * src/pic/pcode.c: added "pic14_"-prefix where needed

862 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
864 (pic14emitRegularMap): ignore config words,
865 (pic14createInterruptVect): moved generating __config directives away

876 fixes #1469504 and #1474602,
877 (pCodeRegOptimizeRegUsage): fixed typo in comment
879 2006-04-24 Borut Razem <borut.razem AT siol.net>
881 * device/examples/main8051.c: deleted - it was removed from CVS
882 24.mar.2000 and after that modified 18.feb.2001, so it reappered

884 * src/SDCCalloc.h: deleted - it was removed from CVS
885 3.feb.2001 and after that modified 18.feb.2001, so it reappered

1123 implemented patch 1120823 Thanks to Willy De la Court (normal
1124 interrupts need an interrupt number now if they are made critical),
1125 and enabled nesting of critical functions though not for gbz80
1126 (genCritical, genEndCritical): added functions
1127 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1128 * src/z80/mappings.i: added "ei" to all mappings

1140 the left operand is shorter than the result (c* = lit-c* + int),
1142 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1145 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1147 * src/.version: increased version number to 2.5.5
1148 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1149 linking is done manually in pic16 port's _linkEdit,
1150 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1151 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1152 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1153 allocate asmop as AOP_ACC,
1154 (aopForRemat): added parameter 'bool result' in function declaration,
1155 (pic16_aopGet): return AOP_ACC when accessing WREG,
1156 (pic16_popGetTempReg): minor modification,

1167 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1168 call to allocReg, not by manually allocating a new one,
1169 (pic16_assignRegisters): now before going through the register
1170 allocating functions mark all registers as free. This eliminates some
1171 side effects resulting from peephole parser done earlier in the backbone
1173 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1231 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1232 which dumps before the function entry point a data byte which represents
1233 the number of the local variables used by the specified function, added
1234 'xinst' for initial support for Extended Instruction Support,
1235 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1236 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1237 port->fun_prefix anymore (may change later),
1238 (genFunction, genEndFunction): do not store/restore local registers for
1239 _main (this should take care the --main-return command line option in
1241 (genOr): removed some legacy pic-port instructions,
1242 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1243 performing operations with SFR's causes data to be written more than
1244 once to each SFR. Perhaps SFRs should be handled in special cases...
1245 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1247 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1248 into account for stack starting position,
1249 (struct OPTIONS pic16_optionsTable): added command line argument
1250 --extended or -y for Extended Instruction Support,
1251 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1252 (deassignLRs): *** perhaps the most important change, old 'for' code
1253 (commented out for reference), didn't account for some registers which
1254 were left marked 'not free' after a pointer operation. The change
1255 reduces register usage a lot in some cases
1257 2006-03-04 Borut Razem <borut.razem AT siol.net>
1259 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3532 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3533 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3534 always available in leading double underscore form. The C99 support is
3535 mostly missing, but it's a start.
3536 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3537 reserved identifier "__data".
3539 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3615 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3617 * device/lib/printf_large.c: removed inline assembly for portability and
3618 readability. Use printf_fast if speed or size are more important.
3619 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3620 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3622 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3624 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3625 prevent compiler warning
3627 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3629 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3630 moved to level 0 and declared as static. Also they are explicit
3631 placed in access bank. This was necessery because some times they
3632 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3633 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3634 optimizations. Currently only compare to unsigned char is implemented,
3635 * src/pic16/gen.c: added fReturnIdx array,
3636 * (struct resolvedIfx) is moved to gen.h and made public,
3637 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3638 * (aopForSym): added an optimization to directly store in stack of
3639 the operand of a SEND iCode,
3640 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3641 but as registers instead (AOP_REG) using the fReturnIdx array,
3642 * (pic16_freeAsmop): remove the freed register from the
3643 _G.sregsAlloc field,
3644 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3645 a compare of 'WREG',
3646 * (pic16_popGetTempRegCond): changed function prototype, now
3647 function takes also a bitVector argument v which holds the current
3648 set of registers that are allocated for stack access by aopForSym,
3649 registers allocated in aopForSym for accessing stack symbols are not
3650 any more part of the functions usedRegs field,
3651 * (genCall): some times aopOp is called for a stack variable to be
3652 send, aopForSym might perform the push, if this is true make sure
3653 that genCall doesn't push the variable twice by testing _G.resDirect,
3654 * (genFunction): changed testing for unspecified interrupt number
3655 from 256 to INTNO_UNSPEC,
3656 * modified selection scheme of frame pointer generation. Previously
3657 if function did use local registers a frame pointer was generated,
3658 now a frame pointer is generated only if function has arguments
3659 (that need PLUSW2 register access), or has stack arguments, or the
3660 compiler is not instructed to omit the frame pointer,
3661 * (genEndFunction): before restoring local registers that were saved
3662 in the function preamble, also restore the registers that *might*
3663 have been allocated for stack access,
3664 * (genRet): removed some old comments,
3665 * (genCmp, the active (RN's) version): added a call to the
3666 pic16_genCmp_special function to perform the compare with a more
3667 robust and optimized way,
3668 * (genInline): a feature has been added in inline code generation,
3669 which allows a wildcard variable substitution when writing inline
3670 assembly. Code is incomplete and experimental therefore undocumented,
3671 * (genCast): changed order of aopOp for result and right to allow
3672 aopForSym to directly load the result if possible,
3673 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3674 perform an optimized compare on some selected special occasions,
3675 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3676 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3677 generate an IVT any more,
3678 * src/pic16/main.c (pic16_optionsTable): added command line option
3680 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3681 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3683 * src/pic16/NOTES: Raphael Neider added in list of active developers
3684 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3685 jumptable_end to prevent bug #,
3686 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3687 inCond and outCond fields,
3688 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3689 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3690 turn off register spilling,
3691 * (packRegsForOneUse): synced with other ports' versions although it
3692 is not used currently,
3693 * (pic16_packRegisters): added an optimization while reading
3694 structure bitfields, some registers may be saved (malloc code is
3695 decreased by 80 bytes)
3697 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3699 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3700 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3701 this can be optimized more?
3703 2005-03-10 Raphael Neider <rneider AT web.de>
3705 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3706 genNearPointerGet): (hopefully) fixed access to bitfields via
3707 pointers (p->bitN = x; and x = p->bitN; failed)
3709 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3752 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3753 to keep the correct label reference count when adding/removing references
3754 to labels. A peephole file using this is appended to patch #1144962.

3886 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3887 (sizeof(sectNames) changed to sizeof(sectName))
3888 Both patches fix segfaults under MinGW.

3894 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
3895 of (byte sized) temporaries (assign them to WREG for now)
3896 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3897 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3898 this might fix SIGSEGVs on MinGW...
3899 * src/SDCCopt.c (killDeadCode): restored original behaviour
3900 (volatile operands might get thrown away though)
3902 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
3904 * src/pic16/gen.c: fixed bug #1106975,

4339 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4341 Adding support for replacing ljmps with sjmps in jumptables
4342 generated for switch statements. For now you need to set the
4343 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4344 Now 4 algorithms for mcs51 jumptable generation are used:
4345 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4346 addresses loaded pc-relative for up to 112 cases and stack-pushing
4347 target addresses loaded with offset from dptr for up to 256 cases.
4349 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
4350 * src/mcs51/main.c: adapted constants for switch table generation
4351 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

4371 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
4373 Large cummulative patch for pic16 port.
4374 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4375 to call when a stack overflow occurs,
4376 * (malloc.h): added CVS Id tag,
4377 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4379 * added libc directory. The current version of LibC contains string
4380 functions, ctype functions and macros and some functions of the
4381 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4382 be extensively tested in the future. Standard disclaimer here.
4383 Library is not automatically build yet. But one can build it by
4384 invoking 'make' inside the libc directory.
4385 * added ADC library under libio. Preliminary version yet.
4387 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4391 temporary registers, its a buggy feature and will be removed,
4392 * (pic16_popGet): set register instance field in AOP_CRY,
4393 * (pic16_outBitC): fixed for results in size greater than 1,
4394 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4395 * (pic16_storeForReturn): optimized return of 0,
4396 * (genCmp): experimental code for new genCmp which uses PIC18's
4397 special compare&skip instructions. Initial tests fail some times
4398 with variables grater than 1 byte in size, so new code is disabled,
4399 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4401 * (genCast): began a fix to optimize the casting of a bit to another
4402 bit, now assigning a bitfield to another bitfield will fail, sorry,
4403 * src/pic16/main.c: disabled the use of lr-support feature,
4404 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4405 * added some function prototypes, added function _debugf prototype,
4406 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
4407 bits with offset (case PO_GPR_BIT),
4408 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4410 * (isBankInstruction): modified to return 0 for no banking instruction,
4411 and 1 for banking instruction,
4412 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4413 caused stop processing pCodes after a inline assembly block,
4414 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4415 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4416 registers when it shouldn't,
4417 * src/pic16/ralloc.c (allocReg): add preliminary support for
4418 supporting a limited set of temporary registers,
4420 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4422 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4423 genDataPointerSet): ensure assignments always copy in MSB to LSB
4425 (loadRegFromAop): recognize CLRH optimization,
4426 (genFunction): optimize RECEIVE iCodes in reentrant functions
4428 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4430 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4431 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4433 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

4442 instead of sjmp to ret
4443 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
4444 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4446 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7428 loaded with the linker search paths (-L arguments) and the libraries
7429 to be linked with the current source (-l arguments). Changes
7430 currently will affect only the pic16 port.
7431 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7432 include path the port specific paths and port specific libraries,

7439 initialization which bypassed the variable initializations block.
7441 * device/lib/pic16/Makefile.rules: removed --penable-stack from
7442 COMPILE_FLAGS and added the --nostdinc option
7444 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7451 Documenting changes from previous commits.
7452 * configure.in (version 1.56),
7453 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7454 when generating output files to configure the pic16 library,
7455 but now I've commented it out, since gputils aren't installed in the
7456 SF compile farm, so library won't compile
7458 * device/lib/Makefile.in (version 1.56): initially I've added in
7459 target 'all' the prerequestive 'model-pic16' so it compiled the
7460 pic16 library, but now I've commented it out for the same reasons
7462 * added targets 'model-pic16' and 'objects-pic16' to compile the
7464 * added target 'port-specific-objects-pic16' to handle the
7465 generated libraries and copy them into the build/ directory
7466 * added target 'clean-intermediate-pic16' to clean intermediate
7467 files into pic16 directory
7468 * in target 'installdirs' added line to create directory pic16 in
7469 the installation path
7471 * device/include/Makefile.in (version 1.11): in target 'install'
7472 added lines to copy all header files to installation path,
7473 * in target 'installdirs' added line create directory for pic16
7474 headers in the installation path
7476 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7489 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7490 option so that it actually works. Made it specific to the z80, since
7491 the gbz80 doesn't have these kinds of I/O ports.
7493 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7495 * device/include/z180.h,

7517 Mainly changes to support compilation of the device libraries
7518 * src/pic16/device.c: stack is allocated via symbol and not
7519 via literal number. The symbol is placed in the corresponding
7520 position of the data ram
7521 * (pic16_dump_section): relocatable and absolute uninitialized
7522 data are now emitted in sorted order to reduce section naming,
7523 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7524 weren't marked as being in the access bank,
7526 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7528 Added portion of GNU PIC Library under the directory
7529 device/include/pic16 and device/lib/pic16. These files
7530 contain the declarations of SFRs for the PIC18Fxx2 devices.
7531 The directory is initialized via configure from toplevel.
7533 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7535 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7536 the spilllocations to be compared correctly
7538 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7540 * src/SDCCast.c (decorateType): fixed bug introduced today
7542 2004-01-12 Borut Razem <borut.razem AT siol.net>

7560 * doc/sdccman.lyx: Moved and added some sections, small changes
7561 all over. Telling LaTeX to be less strict with word spacing
7562 to better keep the right margin. Changed some notes about
7563 maintainance of the ports in section 3.2.1 - is it OK like this?
7565 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7602 UPPER for immediate operands,
7603 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7605 * src/pic16/peeph.def: all peepholes with movff are commented out,
7606 because there is a problem in the pcode peep optimizer,
7607 * src/pic16/ralloc.c: the register allocator can now reuse local

7609 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7611 Added file src/pic16/NOTES with information about program writing on
7612 the current port version.

7644 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7647 * src/z80/main.c: added missed needLinkerScript flags (more than
7648 one port structure defined in these file)
7649 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7684 2004-01-07 Borut Razem <borut.razem AT siol.net>
7686 * support/scripts/sdcc.nsi: update PATH
7687 * support/scripts/sdcc.ico: craeted

7700 include information about variables allocated to the overlay
7703 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7705 * as/mcs51/lkmain.c: Help about -Y option

7717 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7719 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7720 (default behaviour).
7722 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7724 A python script to validate compiler diagnostic messages. It can be
7725 used to verify that sdcc complains about bad c source code and
7726 gives a good location of the error.
7727 * support/valdiag/Makefile,
7728 * support/valdiag/valdiag.py,
7729 * support/valdiag/tests/*
7731 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7746 Bug reported from Jesus Calvino-Fraga
7748 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7750 * sdcc.spec: updated
7751 * device/include/Makefile.in: don't install CVS directories
7752 * device/lib/Makefile.in: added removal of CVS directories after install
7753 * doc/Makefile: fixed install, added local_icons
7754 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7755 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7756 * src/ds390/gen.c (genRightShift): fixed bug #870788
7757 * src/SDCCast.c (decorateType): fixed bug #870781
7759 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7761 PIC16 port related changes:
7762 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7763 added variable stackPos,
7765 * gen.c: genCall, assignResultValue: added support for
7766 pushing/retrieving function parameters to/from stack,
7767 genFunction,genEndFunction: setup stack frame for the
7769 genAddrOf: will be changed according to bug 863624
7771 * added files genutils.c and genutils.h which contain gen*
7772 debugged and optimised functions extracted from gen.c
7774 * glue.c: added variable 'externs' which holds extern symbols,
7775 pic16emitRegularMap: is modified to properly handle relocatable
7776 symbols under the new scheme,
7777 pic16createInterruptVect: is modified
7778 pic16printPublics: is modified to emit 'global' assembler directives,
7779 added pic16_printExterns to print extern symbols,
7780 pic16glue: initializes stack/frame pointer in the beginning of
7781 the assembly output. Temporary hack, will be corrected later,
7782 because gplink yet does not support stack and SDCC does not
7783 yet support a type of crt0.o object to create the final binary.
7785 * Removed many lines that contain 8051 legacy code.
7786 * The code is finally placed under a 'code' directive.
7787 * Added port specific options.
7789 * _process_pragma: simplified since now we do not need *special*
7790 include file to define SFR registers. But a separate header
7791 will be needed. This will be developed later.
7792 * _pic16_parseOptions: added, parses port specific options:
7793 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7794 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7795 --preplace-udata-with=
7797 * _pic16_setDefaultOptions: modified to initialize section names,
7798 but hack is temporarly out of order since it needs improvement.
7799 * _pic16_genAssemblerPreamble: configuration words are emitted by
7800 their address instead of their name. This part is incomplete and
7801 supports only the 18Fxx2 devices. Other devices will emit an error
7802 during assembly since they do not contain the same set of config
7804 * _pic16_genIVT: is modified,
7806 * pcode.c: added definitions for some hardware registers that are needed
7808 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7809 All PCI entries are updated. Now LFSR is supported.
7810 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7811 * added pic16_newpCodeOpLit2 to support instructions with
7812 two literal arguments
7813 * pic16_pCode2str: corrected code that emits assembler instructions
7814 with two literal operands and those that have an access bit modifier
7815 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7816 this fixes a bug which caused some labels to be lost, when an
7817 assembler directive was added, i.e. banksel,
7818 * pic16_FixRegisterBanking: improved logic that causes the insertion
7820 * InlineFunction: functions that are called once, are not any more
7821 inlined. This can be a port option in the future,
7823 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7825 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7826 hold the corresponding uninitialized symbols,
7827 * pic16_allocProcessorRegister: registers have explicit marked the
7829 * pic16_allocInternalRegister: registers are explicit marked as
7831 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7832 processing list, so bit registers were lost,
7835 * ralloc.h: added field 'accessBank' and original symbol operand
7836 in register definition,
7837 * removed the field isMapped from register definition,
7839 ** Several functions have been removed from various sources:
7840 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7841 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7842 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7843 pic16_assignRelocatableRegisters
7845 ** others have been introduced:
7846 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7847 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7849 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7851 * support/scripts/inc2h.pl: changed definition of BIT_AT
7852 to emit 'sbit at' instead of 'bit at'. This was a request.
7854 PIC16 port related preliminary changes:
7855 * gen.c: prefixed function popRegFromString with
7856 pic16_ and all references to it corrected
7857 * pcode.c: all pic16_pc_* hardware registers prefixed
7858 with underscore (_),
7859 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7860 * ralloc.c: newReg(): when register is REG_SFR then
7861 set address to rIdx,
7862 pic16_allocProcessorRegister(): marks register wasUsed=0
7863 pic16_writeUsedRegs(): added a call to assign processor
7864 registers via pic16_assignFixedRegisters
7866 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7868 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7869 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7870 variables in unused register banks. Also the SSEG is placed
7871 wherever there is enough space for it, and IDATA can be anywhere
7872 in internal RAM. For now compile using -Wl-Y[stack_size].
7873 The mem file is different for this option as well, since it
7874 makes no sense of talking about DSEG lenght.
7876 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7878 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7879 in certain cases, e.g. when ROM assignment, patch provided
7880 from Albert den Haan.
7882 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8435 not occur if the control variable is involved with a
8436 relational operator.

8925 A few small changes that speed up the peephole optimizer.
8929 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8931 Try to make the peephole optimizer smarter by maintaining
8932 an association between the assembly source code and the
8933 iCodes that originated them. Put this information to use
8934 with a new peephole rule condition "notVolatile" so that
8935 the rules can be aggressive yet still safe.
8940 * src/mcs51/peeph.def
8942 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8946 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8947 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8948 if the left or right operand symbols have the accuse flag set.
8950 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8952 Changed the type of the result of the ! (NOT) operator to char;
8953 previously it returned the same type as the source. This allows
8954 us to eliminate all the genFloatNot functions (all of its target
8955 implementations were very buggy) since !float can use the same
8958 * src/SDCCicode.c (ast2iCode): ! returns char
8959 * src/mcs51/gen.c (genNot, genNotFloat),
8960 * src/ds390/gen.c (genNot, genNotFloat),
8961 * src/z80/gen.c (genNot, genNotFloat),
8962 * src/pic/gen.c (genNot, genNotFloat),
8963 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

8967 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8968 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8969 during interrupts. Ensure WSAVE is located at a shared bank address.
8970 2. Fixed page selection in some places
8971 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8972 the registers name strings.
8973 4. Fixed "signed / unsigned compare" compiler warnings.
8974 5. The PIC port manages its own allocation of the general purpose
8975 registers, but makes no attempt to reuse them. As a result when
8976 compiling it soon runs out of general purpose registers. Some
8977 additional code was added to the files pcode.c and device.c to walk
8978 through the function call tree and rename the registers so that they
8988 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8989 genPlus() & genMinus() when the result is the same as left or right

8995 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8997 Made bitfield a distinct type from bit so that bitfields
8998 convert as per ANSI C and bits retain their traditional
8999 boolean style behaviour. Implemented bitfield support in
9007 * src/ds390/gen.c: bit v bitfield split
9008 * src/z80/gen.c: New support for bitfields
9009 * support/regression/tests/bitfields.c: reenabled z80,
9012 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9014 Rules 246.x, 247.x relate to bitfields, the others speed up
9015 access to xdata mapped I/O devices.
9017 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9019 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9021 Cleaned up genPackBits and genUnpackBits and added two helper
9022 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9023 for literal assignments in genPackBits (thanks to Frieder for
9029 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9031 Fixed bug #748310 (pointer to function type mishandled when the
9032 function name is omitted). Also fixed a SIGSEGV when a function
9033 attribute (reentrant, etc) is used on a non-function or on a
9034 function but misplaced before the parameter list.
9036 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9038 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9061 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9063 Made the constant following the "interrupt" keyword optional. If
9064 omitted, the function will not automatically be given an entry
9065 in the interrupt vector table (similar to #pragma NOIV, but
9066 less syntacticly kludgy). The interrupt number is also now
9067 range checked. Also fixed a bug in the high order bit example

9081 * src/SDCCicode.c (operandOperation): rewritten some ops
9082 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9083 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9085 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9086 be re-activated by defining REDUCE_LITERALS)
9087 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9088 unsigned, but are signed by default
9089 * src/SDCCval.c (constVal): rearranged
9090 * src/SDCCval.c (valMod): preliminary fix
9091 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9527 * device/lib/gbz80/mul.s
9528 * device/lib/gbz80/stubs.s
9529 * device/lib/z80/mul.s
9530 * device/lib/z80/stubs.s
9531 * src/SDCCsymt.c (initCSupport)
9533 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9535 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
9536 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
9537 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
9538 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
9541 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9543 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9544 the regression tests I'm not brave enough to enable 245.b, 245.c
9545 * doc/sdccman.lyx: added latex preamble for hyperref package.
9546 Using pdflatex this will give you a hyperlinked pdf file with
9547 bookmarks. (prepend '%' before /usepackage if this breaks something)
9549 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9559 * src/SDCCglue.c (printIval): fixed bug #739934
9561 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
9563 Applied patch from bug 737905 (renamed yylineo to mylineno):
9570 * src/pic16/pcode.c: Cleaned warnings
9571 * src/pic16/pcodeflow.c: Cleaned warnings
9572 * src/pic16/pcoderegs.c: Cleaned warnings

9585 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9587 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9588 it can be defined with CFLAGS when running configure
9589 * src/SDCCmain.c: fixed compiling + linking with object files
9591 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9593 * configure.in: configure for pic16 port,
9594 added --disable-pic16-port
9595 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9596 * src/SDCCmain.c: linkOptions is changed to set *,
9597 added if/endif conditional macros to remove options help
9598 messages from optionsTable when a port is not configured, added
9599 support for the PIc16 port in the ports table, when executing
9600 the compiler with no port specified on command line, a default
9601 port is selected with the new macro DEFAULT_PORT which is
9602 defined in port.h, in setDefaultOptions() linkOptions is removed
9603 from initialization assignment, since now it is a set,
9604 parseCmdLine uses setParseWithComma for linkOptions, in
9605 linkEdit() linkOptions are accessed with new function indexSet()
9606 which returns the i'th item of a set variable. See SDCCset.c, in
9607 linkEdit() when calling buildCmdLine(), added linkOptions as
9608 last argument. Now users can pass arguments to gplink via the
9609 -Wl option, main() uses pic16glue() to glue up pic16 programs
9610 * src/SDCCpeeph.c: various changes to support pic16
9611 * src/SDCCset.c: added function void *indexSet(set *, int) to

9619 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
9621 * src/pic16/glue.c: commented out some error producing lines
9622 * src/pic16/main.c: __config directives are commented out to stop
9623 gpasm complaining and test the linkage with gplink, _linkCmd and
9624 _asmCmd changed to be more gplink and gpasm friendly
9625 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9626 produced an error when parsed, peep rule 12 is added to utilize
9627 movff, but it is commented out since the pCode does not support
9628 yet a command with 2 address arguments
9630 2003-05-18 <johan AT balder>
9632 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9633 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9634 2003-05-17 Karl Bongers(apply patches from Martin Helmling)

9657 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9659 2003-05-11 Borut Razem <borut.razem AT siol.net>
9661 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9662 the path of bin directory, so that PATH is the only env. variable, which has to be set
9663 in case of standard installation.
9664 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10693 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10695 * in \sdcc\as\mcs51\ changed these files in order to create an
10696 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10697 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10698 following files to include the previous two files: aslink.dsp,
10699 Makefile.aslink, Makefile.bcc, and Makefile.in.
10701 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10702 .adb instead of .cdb
10704 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10706 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10707 value from option --iram-size.
10709 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10711 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10714 2002-09-18 <wiml AT hhhh.org>
10716 * SDCClrange.h: exposed setFromRange() and setToRange()
10717 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10718 packRegsForAccUse() (bug 542397)
10719 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10720 multiple times and emitting the fetch operations more than once
10721 added aopGetUsesAcc() function to allow binary operators to
10722 fetch their operands in the correct order; made genMinus() emit
10723 compact code for X = LITERAL - Y
10725 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10726 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10727 sprintf() in line 1267.
10729 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10730 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10733 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10734 Changes to aslink (All the changes are marked with 'JCF'):
10736 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10739 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10740 area BSEG. Also moves, if possible, the DATA area down into the internal
10741 ram so more space is available.
10743 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10746 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10747 not bytes. Function summary() which creates a memory usage summary
10748 file with extension .mem. Reports of overlaping stack and small stack
10749 size. If the space for the stack is less than 16 bytes aslink trows a
10752 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10753 the 8051. Option 'y' for memory summary output file.
10755 Changes to sdcc (All the changes are marked with 'JCF'):
10757 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10759 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10760 overlaying area for it (uses RegBankUsed[4]).
10762 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10763 bank zero as used by default. By default aslink locates the stack
10764 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10765 the creation of the .mem file. Delegates the allocation of data area
10766 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10767 the begining of the stack area to aslink.
10769 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10770 glue() in SDCCglue.c creates an area for it.
10772 2002-09-03 Borut Razem <borut.razem AT siol.net>
10773 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10774 sdcc/src/pic/glue.c:
10775 introduced atexit() handler for teporay files removal in case of
10776 errors, assertions, ...
10778 2002-08-29 Borut Razem <borut.razem AT siol.net>
10779 * sdcc/support/cpp2/auto-host_vc_in.h:
10780 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10781 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10782 Maybe there is a similar problem with BORLANDC? It should be checked!
10784 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10785 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10786 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10787 was not executed, and the compiler (cl) launched a warning:
10788 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10790 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10791 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10793 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

10801 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10802 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10803 - added Release configuration in VS projects
10804 - review of compiler an linker options
10805 - VC .exe files are generated in bin_vc directory, not to interfere
10806 with binaries generated from other projects (cygwin, mingw, bcc ...)
10808 * sdcc/src/yacc.dsp: added
10810 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10811 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10812 and insert the version number definitions from .version
10814 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10816 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10817 added - genarate auto-host.h using auto-host_vc_in.h as template
10820 removed from CVS, generated automatically
10822 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10823 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10825 2002-08-11 Borut Razem <borut.razem AT siol.net>
10826 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10828 2002-08-10 Borut Razem <borut.razem AT siol.net>
10829 * src/SDCCmain.c (main):
10830 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10831 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10832 The consequence was that some temporary files were not removed.
10835 unification of code in functions tempfilename() and tempfile():
10836 function tempnam() is defined in Visual Studio 6.0 and .NET
10838 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10840 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10841 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10842 - removed compiler command line option /WX: Treats all warnings as errors
10843 - update a list of source files, included into the project
10845 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10846 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10847 changed project type to Generic Project so that can be correcly converted to VS.NET project
10849 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10851 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

10855 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10856 added return 0 statements after assert() to make compiler happy
10858 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10859 added newline in the def file to keep MSC compiler satisfied
10861 * sdcc/src/z80/gen.c:
10862 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10863 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10864 - solved MSC error in function aopDump()
10866 * sdcc_vc.h: define PREFIX as "\\sdcc"
10868 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11041 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11043 * sdcc/src/SDCCloop.c:
11044 Previous fix was not good. basic blocks that have "break" or "return" are
11045 not really partof a loop , but live ranges used in these blocks should
11046 be live thru the entire loop, so set partOfLoop but don't add them to
