806 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
808 Enabled VPATH feature: changed nearly all Makefiles (149 files).
809 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
811 One basic decision: e.g. src/clean.mk includes further files. In order
812 to make this work there are two solutions:
813 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
814 run configure on them. This way they can use
815 'include $(srcdir)/port-clean.mk'
816 - always include clean.mk by the Makefile at the same level. To avoid
817 that `make clean` tries to include and build Makefile.dep the
818 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
819 implemented, because now even `make uninstall` doesn't create
820 Makefile.in. clean.mk could be eliminated by pasting it in
823 * debugger/mcs51/Makefile.in: build own objects from library sources
824 (SLIB, SDCC) in current directory
826 * configure, configure.in: renamed --disable-device-lib-build in
827 --disable-device-lib; added --enable-doc, the required tools are
828 searched by configure; added result message; the toolchain for the
829 belonging ports are now only built, if the port is enabled.
831 * support/regression/*: all output is written in directory gen, because
832 the fwk and ports directories don't livet in the build tree using vpath
834 * doc/sdccman.lyx: renamed --disable-device-lib-build to
835 --disable-device-lib, added --enable-doc, added section VPATH
837 * sim/ucsim/configure.in,
838 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
839 z80 are enabled by default
841 2006-04-24 Raphael Neider <rneider AT web.de>
843 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
844 to config word, "pic14_"-prefixed some extern functions
845 (pic14_emitConfigWord): emit __config directive(s) if assignment to
846 config word has been found
847 * src/pic/device.h: added prototypes
848 * src/pic/pcode.c: added "pic14_"-prefix where needed
849 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
851 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
853 (pic14emitRegularMap): ignore config words,
854 (pic14createInterruptVect): moved generating __config directives away

865 fixes #1469504 and #1474602,
866 (pCodeRegOptimizeRegUsage): fixed typo in comment
868 2006-04-24 Borut Razem <borut.razem AT siol.net>
870 * device/examples/main8051.c: deleted - it was removed from CVS

873 * src/SDCCalloc.h: deleted - it was removed from CVS

1112 implemented patch 1120823 Thanks to Willy De la Court (normal
1113 interrupts need an interrupt number now if they are made critical),
1114 and enabled nesting of critical functions though not for gbz80
1115 (genCritical, genEndCritical): added functions
1116 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1117 * src/z80/mappings.i: added "ei" to all mappings

1129 the left operand is shorter than the result (c* = lit-c* + int),
1131 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1134 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1136 * src/.version: increased version number to 2.5.5
1137 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1138 linking is done manually in pic16 port's _linkEdit,
1139 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1140 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1141 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1142 allocate asmop as AOP_ACC,
1143 (aopForRemat): added parameter 'bool result' in function declaration,
1144 (pic16_aopGet): return AOP_ACC when accessing WREG,
1145 (pic16_popGetTempReg): minor modification,

1156 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1157 call to allocReg, not by manually allocating a new one,
1158 (pic16_assignRegisters): now before going through the register
1159 allocating functions mark all registers as free. This eliminates some
1160 side effects resulting from peephole parser done earlier in the backbone
1162 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1220 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1221 which dumps before the function entry point a data byte which represents
1222 the number of the local variables used by the specified function, added
1223 'xinst' for initial support for Extended Instruction Support,
1224 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1225 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1226 port->fun_prefix anymore (may change later),
1227 (genFunction, genEndFunction): do not store/restore local registers for
1228 _main (this should take care the --main-return command line option in
1230 (genOr): removed some legacy pic-port instructions,
1231 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1232 performing operations with SFR's causes data to be written more than
1233 once to each SFR. Perhaps SFRs should be handled in special cases...
1234 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1236 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1237 into account for stack starting position,

1239 --extended or -y for Extended Instruction Support,
1240 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1241 (deassignLRs): *** perhaps the most important change, old 'for' code
1242 (commented out for reference), didn't account for some registers which
1243 were left marked 'not free' after a pointer operation. The change
1244 reduces register usage a lot in some cases
1246 2006-03-04 Borut Razem <borut.razem AT siol.net>
1248 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3511 on rIfx (genCmp was broken)
3513 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3515 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3516 * src/z80/main.c (_keywords[]),
3517 * src/SDCCglobal.h (struct options),
3519 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3520 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3521 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3522 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3523 always available in leading double underscore form. The C99 support is
3524 mostly missing, but it's a start.
3525 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3526 reserved identifier "__data".
3528 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3530 * src/mcs51/peeph.def: fixed bug 1170013

3572 immedDom() returning wrong block; probably fixes bug #1160833)
3574 2005-03-20 Borut Razem <borut.razem AT siol.net>
3576 * support/scripts/inc2h.pl: WIN32 port

3580 * device/lib/makefile.in: added abs.c and labs.c
3582 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3584 * device/include/stdint.h: added
3585 * device/lib/abs.c: added

3604 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3606 * device/lib/printf_large.c: removed inline assembly for portability and
3607 readability. Use printf_fast if speed or size are more important.
3608 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3609 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3611 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3613 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3614 prevent compiler warning
3616 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3618 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3619 moved to level 0 and declared as static. Also they are explicit
3620 placed in access bank. This was necessery because some times they
3621 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3622 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3623 optimizations. Currently only compare to unsigned char is implemented,
3624 * src/pic16/gen.c: added fReturnIdx array,
3625 * (struct resolvedIfx) is moved to gen.h and made public,
3626 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3627 * (aopForSym): added an optimization to directly store in stack of
3628 the operand of a SEND iCode,
3629 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3630 but as registers instead (AOP_REG) using the fReturnIdx array,
3631 * (pic16_freeAsmop): remove the freed register from the
3632 _G.sregsAlloc field,
3633 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3634 a compare of 'WREG',
3635 * (pic16_popGetTempRegCond): changed function prototype, now
3636 function takes also a bitVector argument v which holds the current
3637 set of registers that are allocated for stack access by aopForSym,
3638 registers allocated in aopForSym for accessing stack symbols are not
3639 any more part of the functions usedRegs field,
3640 * (genCall): some times aopOp is called for a stack variable to be
3641 send, aopForSym might perform the push, if this is true make sure
3642 that genCall doesn't push the variable twice by testing _G.resDirect,
3643 * (genFunction): changed testing for unspecified interrupt number
3644 from 256 to INTNO_UNSPEC,
3645 * modified selection scheme of frame pointer generation. Previously
3646 if function did use local registers a frame pointer was generated,
3647 now a frame pointer is generated only if function has arguments
3648 (that need PLUSW2 register access), or has stack arguments, or the
3649 compiler is not instructed to omit the frame pointer,
3650 * (genEndFunction): before restoring local registers that were saved
3651 in the function preamble, also restore the registers that *might*
3652 have been allocated for stack access,
3653 * (genRet): removed some old comments,
3654 * (genCmp, the active (RN's) version): added a call to the
3655 pic16_genCmp_special function to perform the compare with a more
3656 robust and optimized way,
3657 * (genInline): a feature has been added in inline code generation,
3658 which allows a wildcard variable substitution when writing inline
3659 assembly. Code is incomplete and experimental therefore undocumented,
3660 * (genCast): changed order of aopOp for result and right to allow
3661 aopForSym to directly load the result if possible,
3662 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3663 perform an optimized compare on some selected special occasions,
3664 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3665 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3666 generate an IVT any more,
3667 * src/pic16/main.c (pic16_optionsTable): added command line option
3669 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3670 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3672 * src/pic16/NOTES: Raphael Neider added in list of active developers
3673 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3674 jumptable_end to prevent bug #,
3675 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3676 inCond and outCond fields,
3677 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3678 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3679 turn off register spilling,
3680 * (packRegsForOneUse): synced with other ports' versions although it
3681 is not used currently,
3682 * (pic16_packRegisters): added an optimization while reading
3683 structure bitfields, some registers may be saved (malloc code is
3684 decreased by 80 bytes)
3686 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3688 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3689 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3690 this can be optimized more?
3692 2005-03-10 Raphael Neider <rneider AT web.de>
3694 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3695 genNearPointerGet): (hopefully) fixed access to bitfields via
3696 pointers (p->bitN = x; and x = p->bitN; failed)
3698 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3741 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3742 to keep the correct label reference count when adding/removing references
3743 to labels. A peephole file using this is appended to patch #1144962.

3875 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3876 (sizeof(sectNames) changed to sizeof(sectName))

3883 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
3884 of (byte sized) temporaries (assign them to WREG for now)
3885 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3886 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3887 this might fix SIGSEGVs on MinGW...
3888 * src/SDCCopt.c (killDeadCode): restored original behaviour
3889 (volatile operands might get thrown away though)
3891 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
3893 * src/pic16/gen.c: fixed bug #1106975,

4330 Adding support for replacing ljmps with sjmps in jumptables
4331 generated for switch statements. For now you need to set the
4332 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4333 Now 4 algorithms for mcs51 jumptable generation are used:
4334 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

4360 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
4362 Large cummulative patch for pic16 port.
4363 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4364 to call when a stack overflow occurs,
4365 * (malloc.h): added CVS Id tag,
4366 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4368 * added libc directory. The current version of LibC contains string
4369 functions, ctype functions and macros and some functions of the
4370 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4371 be extensively tested in the future. Standard disclaimer here.
4372 Library is not automatically build yet. But one can build it by
4373 invoking 'make' inside the libc directory.
4374 * added ADC library under libio. Preliminary version yet.
4376 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
4377 * src/pic16/gen.c (aopForRemat): asmop size is filled by
4378 aopForRemat() now and not by pic16_aopOp(),

4380 temporary registers, its a buggy feature and will be removed,
4381 * (pic16_popGet): set register instance field in AOP_CRY,

4383 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4384 * (pic16_storeForReturn): optimized return of 0,
4385 * (genCmp): experimental code for new genCmp which uses PIC18's
4386 special compare&skip instructions. Initial tests fail some times
4387 with variables grater than 1 byte in size, so new code is disabled,
4388 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4390 * (genCast): began a fix to optimize the casting of a bit to another
4391 bit, now assigning a bitfield to another bitfield will fail, sorry,
4392 * src/pic16/main.c: disabled the use of lr-support feature,
4393 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4394 * added some function prototypes, added function _debugf prototype,
4395 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
4396 bits with offset (case PO_GPR_BIT),
4397 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4399 * (isBankInstruction): modified to return 0 for no banking instruction,
4400 and 1 for banking instruction,
4401 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4402 caused stop processing pCodes after a inline assembly block,
4403 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4404 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4405 registers when it shouldn't,
4406 * src/pic16/ralloc.c (allocReg): add preliminary support for
4407 supporting a limited set of temporary registers,
4409 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4411 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4412 genDataPointerSet): ensure assignments always copy in MSB to LSB
4414 (loadRegFromAop): recognize CLRH optimization,
4415 (genFunction): optimize RECEIVE iCodes in reentrant functions
4417 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4419 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4420 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4422 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

7417 loaded with the linker search paths (-L arguments) and the libraries
7418 to be linked with the current source (-l arguments). Changes
7419 currently will affect only the pic16 port.
7420 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7421 include path the port specific paths and port specific libraries,
7422 * gplink command now contains the $3 argument,

7440 Documenting changes from previous commits.
7441 * configure.in (version 1.56),
7442 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7443 when generating output files to configure the pic16 library,
7444 but now I've commented it out, since gputils aren't installed in the
7445 SF compile farm, so library won't compile
7447 * device/lib/Makefile.in (version 1.56): initially I've added in
7448 target 'all' the prerequestive 'model-pic16' so it compiled the
7449 pic16 library, but now I've commented it out for the same reasons
7451 * added targets 'model-pic16' and 'objects-pic16' to compile the
7453 * added target 'port-specific-objects-pic16' to handle the
7454 generated libraries and copy them into the build/ directory
7455 * added target 'clean-intermediate-pic16' to clean intermediate
7456 files into pic16 directory
7457 * in target 'installdirs' added line to create directory pic16 in
7458 the installation path
7460 * device/include/Makefile.in (version 1.11): in target 'install'
7461 added lines to copy all header files to installation path,
7462 * in target 'installdirs' added line create directory for pic16
7463 headers in the installation path
7465 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7478 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7479 option so that it actually works. Made it specific to the z80, since
7480 the gbz80 doesn't have these kinds of I/O ports.
7482 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7484 * device/include/z180.h,

7497 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7499 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
7500 changed interrupt vector table generation to only emit declared vectors.

7502 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
7504 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7506 Mainly changes to support compilation of the device libraries
7507 * src/pic16/device.c: stack is allocated via symbol and not
7508 via literal number. The symbol is placed in the corresponding
7509 position of the data ram
7510 * (pic16_dump_section): relocatable and absolute uninitialized
7511 data are now emitted in sorted order to reduce section naming,
7512 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7513 weren't marked as being in the access bank,
7515 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7517 Added portion of GNU PIC Library under the directory
7518 device/include/pic16 and device/lib/pic16. These files
7519 contain the declarations of SFRs for the PIC18Fxx2 devices.
7520 The directory is initialized via configure from toplevel.
7522 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7524 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7525 the spilllocations to be compared correctly
7527 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7529 * src/SDCCast.c (decorateType): fixed bug introduced today
7531 2004-01-12 Borut Razem <borut.razem AT siol.net>

7547 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7549 * doc/sdccman.lyx: Moved and added some sections, small changes
7550 all over. Telling LaTeX to be less strict with word spacing
7551 to better keep the right margin. Changed some notes about
7552 maintainance of the ports in section 3.2.1 - is it OK like this?
7554 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7591 UPPER for immediate operands,
7592 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7594 * src/pic16/peeph.def: all peepholes with movff are commented out,
7595 because there is a problem in the pcode peep optimizer,
7596 * src/pic16/ralloc.c: the register allocator can now reuse local

7598 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7600 Added file src/pic16/NOTES with information about program writing on
7601 the current port version.

7633 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7636 * src/z80/main.c: added missed needLinkerScript flags (more than
7637 one port structure defined in these file)
7638 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7654 needLinkerScript flag
7656 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7657 * src/pic/glue.c: added variable udata_section_name to

7661 directive when no overlay data exist
7662 * (picglue): modified to emit uninitialized data segment
7663 according to udata_section_name

7689 include information about variables allocated to the overlay
7692 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7694 * as/mcs51/lkmain.c: Help about -Y option

7706 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7708 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7709 (default behaviour).
7711 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7713 A python script to validate compiler diagnostic messages. It can be
7714 used to verify that sdcc complains about bad c source code and
7715 gives a good location of the error.
7716 * support/valdiag/Makefile,
7717 * support/valdiag/valdiag.py,
7718 * support/valdiag/tests/*

7735 Bug reported from Jesus Calvino-Fraga
7737 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7739 * sdcc.spec: updated
7740 * device/include/Makefile.in: don't install CVS directories
7741 * device/lib/Makefile.in: added removal of CVS directories after install
7742 * doc/Makefile: fixed install, added local_icons
7743 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7744 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7745 * src/ds390/gen.c (genRightShift): fixed bug #870788
7746 * src/SDCCast.c (decorateType): fixed bug #870781
7748 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7750 PIC16 port related changes:
7751 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7752 added variable stackPos,
7754 * gen.c: genCall, assignResultValue: added support for
7755 pushing/retrieving function parameters to/from stack,
7756 genFunction,genEndFunction: setup stack frame for the
7758 genAddrOf: will be changed according to bug 863624
7760 * added files genutils.c and genutils.h which contain gen*
7761 debugged and optimised functions extracted from gen.c
7763 * glue.c: added variable 'externs' which holds extern symbols,
7764 pic16emitRegularMap: is modified to properly handle relocatable
7765 symbols under the new scheme,
7766 pic16createInterruptVect: is modified
7767 pic16printPublics: is modified to emit 'global' assembler directives,
7768 added pic16_printExterns to print extern symbols,
7769 pic16glue: initializes stack/frame pointer in the beginning of
7770 the assembly output. Temporary hack, will be corrected later,
7771 because gplink yet does not support stack and SDCC does not
7772 yet support a type of crt0.o object to create the final binary.
7774 * Removed many lines that contain 8051 legacy code.
7775 * The code is finally placed under a 'code' directive.
7776 * Added port specific options.
7778 * _process_pragma: simplified since now we do not need *special*
7779 include file to define SFR registers. But a separate header
7780 will be needed. This will be developed later.
7781 * _pic16_parseOptions: added, parses port specific options:
7782 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7783 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7784 --preplace-udata-with=
7786 * _pic16_setDefaultOptions: modified to initialize section names,
7787 but hack is temporarly out of order since it needs improvement.
7788 * _pic16_genAssemblerPreamble: configuration words are emitted by
7789 their address instead of their name. This part is incomplete and
7790 supports only the 18Fxx2 devices. Other devices will emit an error
7791 during assembly since they do not contain the same set of config
7793 * _pic16_genIVT: is modified,
7795 * pcode.c: added definitions for some hardware registers that are needed
7797 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7798 All PCI entries are updated. Now LFSR is supported.
7799 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7800 * added pic16_newpCodeOpLit2 to support instructions with
7801 two literal arguments
7802 * pic16_pCode2str: corrected code that emits assembler instructions
7803 with two literal operands and those that have an access bit modifier
7804 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7805 this fixes a bug which caused some labels to be lost, when an
7806 assembler directive was added, i.e. banksel,
7807 * pic16_FixRegisterBanking: improved logic that causes the insertion
7809 * InlineFunction: functions that are called once, are not any more
7810 inlined. This can be a port option in the future,
7812 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7814 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7815 hold the corresponding uninitialized symbols,
7816 * pic16_allocProcessorRegister: registers have explicit marked the
7818 * pic16_allocInternalRegister: registers are explicit marked as
7820 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7821 processing list, so bit registers were lost,
7824 * ralloc.h: added field 'accessBank' and original symbol operand
7825 in register definition,
7826 * removed the field isMapped from register definition,
7828 ** Several functions have been removed from various sources:
7829 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7830 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7831 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7832 pic16_assignRelocatableRegisters
7834 ** others have been introduced:
7835 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7836 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7838 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7840 * support/scripts/inc2h.pl: changed definition of BIT_AT
7841 to emit 'sbit at' instead of 'bit at'. This was a request.
7843 PIC16 port related preliminary changes:
7844 * gen.c: prefixed function popRegFromString with
7845 pic16_ and all references to it corrected
7846 * pcode.c: all pic16_pc_* hardware registers prefixed
7847 with underscore (_),
7848 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7849 * ralloc.c: newReg(): when register is REG_SFR then
7850 set address to rIdx,
7851 pic16_allocProcessorRegister(): marks register wasUsed=0
7852 pic16_writeUsedRegs(): added a call to assign processor
7853 registers via pic16_assignFixedRegisters
7855 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7857 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7858 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7859 variables in unused register banks. Also the SSEG is placed
7860 wherever there is enough space for it, and IDATA can be anywhere
7861 in internal RAM. For now compile using -Wl-Y[stack_size].
7862 The mem file is different for this option as well, since it
7863 makes no sense of talking about DSEG lenght.
7865 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7867 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7868 in certain cases, e.g. when ROM assignment, patch provided
7869 from Albert den Haan.
7871 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8914 A few small changes that speed up the peephole optimizer.
8918 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8920 Try to make the peephole optimizer smarter by maintaining
8921 an association between the assembly source code and the
8922 iCodes that originated them. Put this information to use
8923 with a new peephole rule condition "notVolatile" so that
8924 the rules can be aggressive yet still safe.
8929 * src/mcs51/peeph.def
8931 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8935 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8936 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8937 if the left or right operand symbols have the accuse flag set.
8939 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8941 Changed the type of the result of the ! (NOT) operator to char;
8942 previously it returned the same type as the source. This allows
8943 us to eliminate all the genFloatNot functions (all of its target
8944 implementations were very buggy) since !float can use the same
8947 * src/SDCCicode.c (ast2iCode): ! returns char

8956 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8957 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8958 during interrupts. Ensure WSAVE is located at a shared bank address.
8959 2. Fixed page selection in some places
8960 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8961 the registers name strings.
8962 4. Fixed "signed / unsigned compare" compiler warnings.
8963 5. The PIC port manages its own allocation of the general purpose
8964 registers, but makes no attempt to reuse them. As a result when
8965 compiling it soon runs out of general purpose registers. Some
8966 additional code was added to the files pcode.c and device.c to walk
8967 through the function call tree and rename the registers so that they
8977 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8984 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8986 Made bitfield a distinct type from bit so that bitfields
8987 convert as per ANSI C and bits retain their traditional
8988 boolean style behaviour. Implemented bitfield support in
8996 * src/ds390/gen.c: bit v bitfield split
8997 * src/z80/gen.c: New support for bitfields
8998 * support/regression/tests/bitfields.c: reenabled z80,
9001 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9003 Rules 246.x, 247.x relate to bitfields, the others speed up
9004 access to xdata mapped I/O devices.
9006 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9008 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9010 Cleaned up genPackBits and genUnpackBits and added two helper
9011 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9012 for literal assignments in genPackBits (thanks to Frieder for
9018 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9020 Fixed bug #748310 (pointer to function type mishandled when the
9021 function name is omitted). Also fixed a SIGSEGV when a function
9022 attribute (reentrant, etc) is used on a non-function or on a
9023 function but misplaced before the parameter list.

9050 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9052 Made the constant following the "interrupt" keyword optional. If
9053 omitted, the function will not automatically be given an entry
9054 in the interrupt vector table (similar to #pragma NOIV, but
9055 less syntacticly kludgy). The interrupt number is also now
9056 range checked. Also fixed a bug in the high order bit example

9077 unsigned, but are signed by default
9078 * src/SDCCval.c (constVal): rearranged
9079 * src/SDCCval.c (valMod): preliminary fix
9080 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9532 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9533 the regression tests I'm not brave enough to enable 245.b, 245.c
9534 * doc/sdccman.lyx: added latex preamble for hyperref package.
9535 Using pdflatex this will give you a hyperlinked pdf file with
9536 bookmarks. (prepend '%' before /usepackage if this breaks something)

9577 it can be defined with CFLAGS when running configure
9578 * src/SDCCmain.c: fixed compiling + linking with object files
9580 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9583 added --disable-pic16-port
9584 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9585 * src/SDCCmain.c: linkOptions is changed to set *,
9586 added if/endif conditional macros to remove options help
9587 messages from optionsTable when a port is not configured, added
9588 support for the PIc16 port in the ports table, when executing
9589 the compiler with no port specified on command line, a default
9590 port is selected with the new macro DEFAULT_PORT which is
9591 defined in port.h, in setDefaultOptions() linkOptions is removed
9592 from initialization assignment, since now it is a set,
9593 parseCmdLine uses setParseWithComma for linkOptions, in
9594 linkEdit() linkOptions are accessed with new function indexSet()
9595 which returns the i'th item of a set variable. See SDCCset.c, in
9596 linkEdit() when calling buildCmdLine(), added linkOptions as
9597 last argument. Now users can pass arguments to gplink via the
9598 -Wl option, main() uses pic16glue() to glue up pic16 programs
9599 * src/SDCCpeeph.c: various changes to support pic16

9610 * src/pic16/glue.c: commented out some error producing lines
9611 * src/pic16/main.c: __config directives are commented out to stop
9612 gpasm complaining and test the linkage with gplink, _linkCmd and
9613 _asmCmd changed to be more gplink and gpasm friendly
9614 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9615 produced an error when parsed, peep rule 12 is added to utilize
9616 movff, but it is commented out since the pCode does not support
9617 yet a command with 2 address arguments
9619 2003-05-18 <johan AT balder>
9621 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9646 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9648 2003-05-11 Borut Razem <borut.razem AT siol.net>
9650 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9651 the path of bin directory, so that PATH is the only env. variable, which has to be set
9652 in case of standard installation.
9653 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10682 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10684 * in \sdcc\as\mcs51\ changed these files in order to create an
10685 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10686 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10687 following files to include the previous two files: aslink.dsp,
10688 Makefile.aslink, Makefile.bcc, and Makefile.in.
10690 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10691 .adb instead of .cdb
10693 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10695 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10696 value from option --iram-size.
10698 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10700 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10703 2002-09-18 <wiml AT hhhh.org>
10705 * SDCClrange.h: exposed setFromRange() and setToRange()
10706 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10707 packRegsForAccUse() (bug 542397)
10708 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10709 multiple times and emitting the fetch operations more than once
10710 added aopGetUsesAcc() function to allow binary operators to
10711 fetch their operands in the correct order; made genMinus() emit
10712 compact code for X = LITERAL - Y
10714 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10715 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10716 sprintf() in line 1267.
10718 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10719 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10722 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10723 Changes to aslink (All the changes are marked with 'JCF'):
10725 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10728 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10729 area BSEG. Also moves, if possible, the DATA area down into the internal
10730 ram so more space is available.
10732 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10735 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10736 not bytes. Function summary() which creates a memory usage summary
10737 file with extension .mem. Reports of overlaping stack and small stack
10738 size. If the space for the stack is less than 16 bytes aslink trows a
10741 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10742 the 8051. Option 'y' for memory summary output file.
10744 Changes to sdcc (All the changes are marked with 'JCF'):
10746 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10748 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10749 overlaying area for it (uses RegBankUsed[4]).
10751 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10752 bank zero as used by default. By default aslink locates the stack
10753 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10754 the creation of the .mem file. Delegates the allocation of data area
10755 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10756 the begining of the stack area to aslink.
10758 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10759 glue() in SDCCglue.c creates an area for it.
10761 2002-09-03 Borut Razem <borut.razem AT siol.net>
10762 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10763 sdcc/src/pic/glue.c:
10764 introduced atexit() handler for teporay files removal in case of
10765 errors, assertions, ...
10767 2002-08-29 Borut Razem <borut.razem AT siol.net>
10768 * sdcc/support/cpp2/auto-host_vc_in.h:
10769 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10770 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10771 Maybe there is a similar problem with BORLANDC? It should be checked!
10773 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10774 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10775 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10776 was not executed, and the compiler (cl) launched a warning:
10777 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10779 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10780 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10782 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

10791 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10792 - added Release configuration in VS projects
10793 - review of compiler an linker options
10794 - VC .exe files are generated in bin_vc directory, not to interfere
10795 with binaries generated from other projects (cygwin, mingw, bcc ...)
10797 * sdcc/src/yacc.dsp: added
10799 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10800 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10801 and insert the version number definitions from .version
10803 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10805 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10806 added - genarate auto-host.h using auto-host_vc_in.h as template
10809 removed from CVS, generated automatically
10811 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10812 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10814 2002-08-11 Borut Razem <borut.razem AT siol.net>
10815 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10817 2002-08-10 Borut Razem <borut.razem AT siol.net>
10818 * src/SDCCmain.c (main):
10819 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10820 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10821 The consequence was that some temporary files were not removed.
10824 unification of code in functions tempfilename() and tempfile():
10825 function tempnam() is defined in Visual Studio 6.0 and .NET
10827 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10829 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10830 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10831 - removed compiler command line option /WX: Treats all warnings as errors
10832 - update a list of source files, included into the project
10834 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10835 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10836 changed project type to Generic Project so that can be correcly converted to VS.NET project
10838 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10840 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10842 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10844 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10845 added return 0 statements after assert() to make compiler happy
10847 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10848 added newline in the def file to keep MSC compiler satisfied
10850 * sdcc/src/z80/gen.c:
10851 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10852 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10853 - solved MSC error in function aopDump()
10855 * sdcc_vc.h: define PREFIX as "\\sdcc"
10857 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11030 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11032 * sdcc/src/SDCCloop.c:
11033 Previous fix was not good. basic blocks that have "break" or "return" are
11034 not really partof a loop , but live ranges used in these blocks should
11035 be live thru the entire loop, so set partOfLoop but don't add them to
