2907 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2909 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2910 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2912 One basic decision: e.g. src/clean.mk includes further files. In order
2913 to make this work there are two solutions:
2914 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2915 run configure on them. This way they can use
2916 'include $(srcdir)/port-clean.mk'
2917 - always include clean.mk by the Makefile at the same level. To avoid
2918 that `make clean` tries to include and build Makefile.dep the
2919 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2920 implemented, because now even `make uninstall` doesn't create
2921 Makefile.in. clean.mk could be eliminated by pasting it in
2924 * debugger/mcs51/Makefile.in: build own objects from library sources
2925 (SLIB, SDCC) in current directory
2927 * configure, configure.in: renamed --disable-device-lib-build in
2928 --disable-device-lib; added --enable-doc, the required tools are
2929 searched by configure; added result message; the toolchain for the
2930 belonging ports are now only built, if the port is enabled.
2932 * support/regression/*: all output is written in directory gen, because
2933 the fwk and ports directories don't livet in the build tree using vpath
2935 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2936 --disable-device-lib, added --enable-doc, added section VPATH
2938 * sim/ucsim/configure.in,
2939 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2940 z80 are enabled by default
2942 2006-04-24 Raphael Neider <rneider AT web.de>
2944 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2945 to config word, "pic14_"-prefixed some extern functions
2946 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2947 config word has been found
2948 * src/pic/device.h: added prototypes
2949 * src/pic/pcode.c: added "pic14_"-prefix where needed
2950 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2952 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2955 (pic14createInterruptVect): moved generating __config directives away

2966 fixes #1469504 and #1474602,
2967 (pCodeRegOptimizeRegUsage): fixed typo in comment
2969 2006-04-24 Borut Razem <borut.razem AT siol.net>
2971 * device/examples/main8051.c: deleted - it was removed from CVS
2972 24.mar.2000 and after that modified 18.feb.2001, so it reappered
2973 after the transition to Subversion
2974 * src/SDCCalloc.h: deleted - it was removed from CVS
2975 3.feb.2001 and after that modified 18.feb.2001, so it reappered

3213 implemented patch 1120823 Thanks to Willy De la Court (normal
3214 interrupts need an interrupt number now if they are made critical),
3215 and enabled nesting of critical functions though not for gbz80
3216 (genCritical, genEndCritical): added functions
3217 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3218 * src/z80/mappings.i: added "ei" to all mappings

3230 the left operand is shorter than the result (c* = lit-c* + int),
3232 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3235 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3237 * src/.version: increased version number to 2.5.5
3238 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3239 linking is done manually in pic16 port's _linkEdit,
3240 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3241 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3242 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3243 allocate asmop as AOP_ACC,
3244 (aopForRemat): added parameter 'bool result' in function declaration,
3245 (pic16_aopGet): return AOP_ACC when accessing WREG,
3246 (pic16_popGetTempReg): minor modification,

3257 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3258 call to allocReg, not by manually allocating a new one,
3259 (pic16_assignRegisters): now before going through the register
3260 allocating functions mark all registers as free. This eliminates some
3261 side effects resulting from peephole parser done earlier in the backbone
3263 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

3321 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3322 which dumps before the function entry point a data byte which represents
3323 the number of the local variables used by the specified function, added
3324 'xinst' for initial support for Extended Instruction Support,
3325 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3326 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3327 port->fun_prefix anymore (may change later),
3328 (genFunction, genEndFunction): do not store/restore local registers for
3329 _main (this should take care the --main-return command line option in
3331 (genOr): removed some legacy pic-port instructions,
3332 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3333 performing operations with SFR's causes data to be written more than
3334 once to each SFR. Perhaps SFRs should be handled in special cases...
3335 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3337 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3338 into account for stack starting position,
3339 (struct OPTIONS pic16_optionsTable): added command line argument
3340 --extended or -y for Extended Instruction Support,
3341 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3342 (deassignLRs): *** perhaps the most important change, old 'for' code
3343 (commented out for reference), didn't account for some registers which
3344 were left marked 'not free' after a pointer operation. The change
3345 reduces register usage a lot in some cases
3347 2006-03-04 Borut Razem <borut.razem AT siol.net>

5614 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5616 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

5620 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
5621 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
5622 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
5623 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
5624 always available in leading double underscore form. The C99 support is
5625 mostly missing, but it's a start.
5626 * support/regression/tests/bug-227710.c: fixed nonconforming use of
5627 reserved identifier "__data".
5629 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

5673 immedDom() returning wrong block; probably fixes bug #1160833)
5675 2005-03-20 Borut Razem <borut.razem AT siol.net>
5677 * support/scripts/inc2h.pl: WIN32 port

5681 * device/lib/makefile.in: added abs.c and labs.c
5683 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
5685 * device/include/stdint.h: added
5686 * device/lib/abs.c: added

5705 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5707 * device/lib/printf_large.c: removed inline assembly for portability and
5708 readability. Use printf_fast if speed or size are more important.
5709 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5710 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5712 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5714 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5715 prevent compiler warning
5717 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5719 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5720 moved to level 0 and declared as static. Also they are explicit
5721 placed in access bank. This was necessery because some times they
5722 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5723 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5724 optimizations. Currently only compare to unsigned char is implemented,
5725 * src/pic16/gen.c: added fReturnIdx array,
5726 * (struct resolvedIfx) is moved to gen.h and made public,
5727 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5728 * (aopForSym): added an optimization to directly store in stack of
5729 the operand of a SEND iCode,
5730 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5731 but as registers instead (AOP_REG) using the fReturnIdx array,
5732 * (pic16_freeAsmop): remove the freed register from the
5733 _G.sregsAlloc field,
5734 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5735 a compare of 'WREG',
5736 * (pic16_popGetTempRegCond): changed function prototype, now
5737 function takes also a bitVector argument v which holds the current
5738 set of registers that are allocated for stack access by aopForSym,
5739 registers allocated in aopForSym for accessing stack symbols are not
5740 any more part of the functions usedRegs field,
5741 * (genCall): some times aopOp is called for a stack variable to be
5742 send, aopForSym might perform the push, if this is true make sure
5743 that genCall doesn't push the variable twice by testing _G.resDirect,
5744 * (genFunction): changed testing for unspecified interrupt number
5745 from 256 to INTNO_UNSPEC,
5746 * modified selection scheme of frame pointer generation. Previously
5747 if function did use local registers a frame pointer was generated,
5748 now a frame pointer is generated only if function has arguments
5749 (that need PLUSW2 register access), or has stack arguments, or the
5750 compiler is not instructed to omit the frame pointer,
5751 * (genEndFunction): before restoring local registers that were saved
5752 in the function preamble, also restore the registers that *might*
5753 have been allocated for stack access,
5754 * (genRet): removed some old comments,
5755 * (genCmp, the active (RN's) version): added a call to the
5756 pic16_genCmp_special function to perform the compare with a more
5757 robust and optimized way,
5758 * (genInline): a feature has been added in inline code generation,
5759 which allows a wildcard variable substitution when writing inline
5760 assembly. Code is incomplete and experimental therefore undocumented,
5761 * (genCast): changed order of aopOp for result and right to allow
5762 aopForSym to directly load the result if possible,
5763 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5764 perform an optimized compare on some selected special occasions,
5765 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5766 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5767 generate an IVT any more,
5768 * src/pic16/main.c (pic16_optionsTable): added command line option
5770 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5771 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5773 * src/pic16/NOTES: Raphael Neider added in list of active developers
5774 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5775 jumptable_end to prevent bug #,
5776 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5777 inCond and outCond fields,
5778 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5779 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5780 turn off register spilling,
5781 * (packRegsForOneUse): synced with other ports' versions although it
5782 is not used currently,
5783 * (pic16_packRegisters): added an optimization while reading
5784 structure bitfields, some registers may be saved (malloc code is
5785 decreased by 80 bytes)
5787 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5789 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5790 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5791 this can be optimized more?
5793 2005-03-10 Raphael Neider <rneider AT web.de>
5795 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5796 genNearPointerGet): (hopefully) fixed access to bitfields via
5797 pointers (p->bitN = x; and x = p->bitN; failed)
5799 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5842 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
5843 to keep the correct label reference count when adding/removing references
5844 to labels. A peephole file using this is appended to patch #1144962.

5976 * src/pic16/main.c (_process_pragma): fixed another malloc bug
5977 (sizeof(sectNames) changed to sizeof(sectName))
5978 Both patches fix segfaults under MinGW.

5984 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
5985 of (byte sized) temporaries (assign them to WREG for now)
5986 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5987 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5988 this might fix SIGSEGVs on MinGW...
5989 * src/SDCCopt.c (killDeadCode): restored original behaviour
5990 (volatile operands might get thrown away though)
5992 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

6429 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6431 Adding support for replacing ljmps with sjmps in jumptables
6432 generated for switch statements. For now you need to set the
6433 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6434 Now 4 algorithms for mcs51 jumptable generation are used:
6435 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6436 addresses loaded pc-relative for up to 112 cases and stack-pushing
6437 target addresses loaded with offset from dptr for up to 256 cases.
6439 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
6440 * src/mcs51/main.c: adapted constants for switch table generation
6441 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

6461 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
6463 Large cummulative patch for pic16 port.
6464 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6465 to call when a stack overflow occurs,
6466 * (malloc.h): added CVS Id tag,
6467 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6469 * added libc directory. The current version of LibC contains string
6470 functions, ctype functions and macros and some functions of the
6471 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6472 be extensively tested in the future. Standard disclaimer here.
6473 Library is not automatically build yet. But one can build it by
6474 invoking 'make' inside the libc directory.
6475 * added ADC library under libio. Preliminary version yet.
6477 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
6478 * src/pic16/gen.c (aopForRemat): asmop size is filled by
6479 aopForRemat() now and not by pic16_aopOp(),
6480 * (pic16_popGetTempReg): removed warning messgae when allocating
6481 temporary registers, its a buggy feature and will be removed,
6482 * (pic16_popGet): set register instance field in AOP_CRY,
6483 * (pic16_outBitC): fixed for results in size greater than 1,
6484 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6485 * (pic16_storeForReturn): optimized return of 0,
6486 * (genCmp): experimental code for new genCmp which uses PIC18's
6487 special compare&skip instructions. Initial tests fail some times
6488 with variables grater than 1 byte in size, so new code is disabled,
6489 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6491 * (genCast): began a fix to optimize the casting of a bit to another
6492 bit, now assigning a bitfield to another bitfield will fail, sorry,
6493 * src/pic16/main.c: disabled the use of lr-support feature,
6494 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
6495 * added some function prototypes, added function _debugf prototype,
6496 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
6497 bits with offset (case PO_GPR_BIT),
6498 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
6500 * (isBankInstruction): modified to return 0 for no banking instruction,
6501 and 1 for banking instruction,
6502 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6503 caused stop processing pCodes after a inline assembly block,
6504 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
6505 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
6506 registers when it shouldn't,
6507 * src/pic16/ralloc.c (allocReg): add preliminary support for
6508 supporting a limited set of temporary registers,
6510 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6512 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6513 genDataPointerSet): ensure assignments always copy in MSB to LSB
6515 (loadRegFromAop): recognize CLRH optimization,
6516 (genFunction): optimize RECEIVE iCodes in reentrant functions
6518 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6520 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
6521 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

6530 * device/lib/_gptrgetc.c (_gptrgetc),
6531 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
6532 instead of sjmp to ret
6533 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
6534 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
6536 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

9518 loaded with the linker search paths (-L arguments) and the libraries
9519 to be linked with the current source (-l arguments). Changes
9520 currently will affect only the pic16 port.
9521 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9522 include path the port specific paths and port specific libraries,
9523 * gplink command now contains the $3 argument,
9524 * src/pic16/device.h,
9525 * src/pic16/device.c,: structure PIC_device is made public and
9526 renamed to PIC16_device, the same for variable Pics which is renamed
9527 to Pics16. Updated all references to them.
9528 * src/pic16/glue.c (pic16glue): corrected bug with code
9529 initialization which bypassed the variable initializations block.
9531 * device/lib/pic16/Makefile.rules: removed --penable-stack from
9532 COMPILE_FLAGS and added the --nostdinc option
9534 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9536 * device/include/mc68hc908jb8.h: Register defs for another member
9537 of the hc08 family. Contributed by Bjorn Bringert - thanks!
9539 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
9541 Documenting changes from previous commits.
9542 * configure.in (version 1.56),
9543 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9544 when generating output files to configure the pic16 library,
9545 but now I've commented it out, since gputils aren't installed in the
9546 SF compile farm, so library won't compile
9548 * device/lib/Makefile.in (version 1.56): initially I've added in
9549 target 'all' the prerequestive 'model-pic16' so it compiled the
9550 pic16 library, but now I've commented it out for the same reasons
9552 * added targets 'model-pic16' and 'objects-pic16' to compile the
9554 * added target 'port-specific-objects-pic16' to handle the
9555 generated libraries and copy them into the build/ directory
9556 * added target 'clean-intermediate-pic16' to clean intermediate
9557 files into pic16 directory
9558 * in target 'installdirs' added line to create directory pic16 in
9559 the installation path
9561 * device/include/Makefile.in (version 1.11): in target 'install'
9562 added lines to copy all header files to installation path,
9563 * in target 'installdirs' added line create directory for pic16
9564 headers in the installation path

9579 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9580 option so that it actually works. Made it specific to the z80, since
9581 the gbz80 doesn't have these kinds of I/O ports.
9583 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9585 * device/include/z180.h,

9607 Mainly changes to support compilation of the device libraries
9608 * src/pic16/device.c: stack is allocated via symbol and not
9609 via literal number. The symbol is placed in the corresponding
9610 position of the data ram
9611 * (pic16_dump_section): relocatable and absolute uninitialized
9612 data are now emitted in sorted order to reduce section naming,
9613 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9614 weren't marked as being in the access bank,
9616 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9618 Added portion of GNU PIC Library under the directory
9619 device/include/pic16 and device/lib/pic16. These files
9620 contain the declarations of SFRs for the PIC18Fxx2 devices.
9621 The directory is initialized via configure from toplevel.
9623 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
9625 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
9626 the spilllocations to be compared correctly
9628 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9630 * src/SDCCast.c (decorateType): fixed bug introduced today
9632 2004-01-12 Borut Razem <borut.razem AT siol.net>

9650 * doc/sdccman.lyx: Moved and added some sections, small changes
9651 all over. Telling LaTeX to be less strict with word spacing
9652 to better keep the right margin. Changed some notes about
9653 maintainance of the ports in section 3.2.1 - is it OK like this?
9655 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

9692 UPPER for immediate operands,
9693 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9695 * src/pic16/peeph.def: all peepholes with movff are commented out,
9696 because there is a problem in the pcode peep optimizer,
9697 * src/pic16/ralloc.c: the register allocator can now reuse local

9699 * src/pic16/ralloc.h: added flag isLocal in structure regs,
9701 Added file src/pic16/NOTES with information about program writing on
9702 the current port version.

9734 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9737 * src/z80/main.c: added missed needLinkerScript flags (more than
9738 one port structure defined in these file)
9739 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

9762 directive when no overlay data exist
9763 * (picglue): modified to emit uninitialized data segment
9764 according to udata_section_name

9774 2004-01-07 Borut Razem <borut.razem AT siol.net>
9776 * support/scripts/sdcc.nsi: update PATH
9777 * support/scripts/sdcc.ico: craeted

9790 include information about variables allocated to the overlay
9793 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9795 * as/mcs51/lkmain.c: Help about -Y option

9807 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9809 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9810 (default behaviour).
9812 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9814 A python script to validate compiler diagnostic messages. It can be
9815 used to verify that sdcc complains about bad c source code and
9816 gives a good location of the error.
9817 * support/valdiag/Makefile,
9818 * support/valdiag/valdiag.py,
9819 * support/valdiag/tests/*
9821 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9836 Bug reported from Jesus Calvino-Fraga
9838 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9840 * sdcc.spec: updated
9841 * device/include/Makefile.in: don't install CVS directories
9842 * device/lib/Makefile.in: added removal of CVS directories after install
9843 * doc/Makefile: fixed install, added local_icons
9844 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9845 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9846 * src/ds390/gen.c (genRightShift): fixed bug #870788
9847 * src/SDCCast.c (decorateType): fixed bug #870781
9849 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9851 PIC16 port related changes:
9852 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9853 added variable stackPos,
9855 * gen.c: genCall, assignResultValue: added support for
9856 pushing/retrieving function parameters to/from stack,
9857 genFunction,genEndFunction: setup stack frame for the
9859 genAddrOf: will be changed according to bug 863624
9861 * added files genutils.c and genutils.h which contain gen*
9862 debugged and optimised functions extracted from gen.c
9864 * glue.c: added variable 'externs' which holds extern symbols,
9865 pic16emitRegularMap: is modified to properly handle relocatable
9866 symbols under the new scheme,
9867 pic16createInterruptVect: is modified
9868 pic16printPublics: is modified to emit 'global' assembler directives,
9869 added pic16_printExterns to print extern symbols,
9870 pic16glue: initializes stack/frame pointer in the beginning of
9871 the assembly output. Temporary hack, will be corrected later,
9872 because gplink yet does not support stack and SDCC does not
9873 yet support a type of crt0.o object to create the final binary.
9875 * Removed many lines that contain 8051 legacy code.
9876 * The code is finally placed under a 'code' directive.
9877 * Added port specific options.
9879 * _process_pragma: simplified since now we do not need *special*
9880 include file to define SFR registers. But a separate header
9881 will be needed. This will be developed later.
9882 * _pic16_parseOptions: added, parses port specific options:
9883 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9884 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9885 --preplace-udata-with=
9887 * _pic16_setDefaultOptions: modified to initialize section names,
9888 but hack is temporarly out of order since it needs improvement.
9889 * _pic16_genAssemblerPreamble: configuration words are emitted by
9890 their address instead of their name. This part is incomplete and
9891 supports only the 18Fxx2 devices. Other devices will emit an error
9892 during assembly since they do not contain the same set of config
9894 * _pic16_genIVT: is modified,
9896 * pcode.c: added definitions for some hardware registers that are needed
9898 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9899 All PCI entries are updated. Now LFSR is supported.
9900 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9901 * added pic16_newpCodeOpLit2 to support instructions with
9902 two literal arguments
9903 * pic16_pCode2str: corrected code that emits assembler instructions
9904 with two literal operands and those that have an access bit modifier
9905 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9906 this fixes a bug which caused some labels to be lost, when an
9907 assembler directive was added, i.e. banksel,
9908 * pic16_FixRegisterBanking: improved logic that causes the insertion
9910 * InlineFunction: functions that are called once, are not any more
9911 inlined. This can be a port option in the future,
9913 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9915 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9916 hold the corresponding uninitialized symbols,
9917 * pic16_allocProcessorRegister: registers have explicit marked the
9919 * pic16_allocInternalRegister: registers are explicit marked as
9921 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9922 processing list, so bit registers were lost,
9925 * ralloc.h: added field 'accessBank' and original symbol operand
9926 in register definition,
9927 * removed the field isMapped from register definition,
9929 ** Several functions have been removed from various sources:
9930 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9931 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9932 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9933 pic16_assignRelocatableRegisters
9935 ** others have been introduced:
9936 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9937 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9939 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9941 * support/scripts/inc2h.pl: changed definition of BIT_AT
9942 to emit 'sbit at' instead of 'bit at'. This was a request.
9944 PIC16 port related preliminary changes:
9945 * gen.c: prefixed function popRegFromString with
9946 pic16_ and all references to it corrected
9947 * pcode.c: all pic16_pc_* hardware registers prefixed
9948 with underscore (_),
9949 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9950 * ralloc.c: newReg(): when register is REG_SFR then
9951 set address to rIdx,
9952 pic16_allocProcessorRegister(): marks register wasUsed=0
9953 pic16_writeUsedRegs(): added a call to assign processor
9954 registers via pic16_assignFixedRegisters
9956 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9958 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9959 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9960 variables in unused register banks. Also the SSEG is placed
9961 wherever there is enough space for it, and IDATA can be anywhere
9962 in internal RAM. For now compile using -Wl-Y[stack_size].
9963 The mem file is different for this option as well, since it
9964 makes no sense of talking about DSEG lenght.
9966 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9968 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9969 in certain cases, e.g. when ROM assignment, patch provided
9970 from Albert den Haan.
9972 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10959 and JUMPTABLE iCodes properly now (worked by accident before)
10960 * src/mcs51/gen.c (leftRightUseAcc),
10961 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10962 iCode properly now. Use getSize instead of nRegs since a & b
10963 aren't part of the nRegs tally.
10965 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10967 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
10968 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
10969 before instructions that use the _STATUS register
10971 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
10973 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
10974 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
10975 fetching of the pointer
10976 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
10977 copied from genNearPointerSet()
10978 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10979 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10980 If they pop r0/r1 they must be called in the opposite order than aopOp().
10981 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10982 (resp. --stack-auto), prepared for --xstack
10984 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10986 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10988 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10990 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
10991 these ports have their own __sdcc_external_start()
10993 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10995 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10996 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10997 type for bits was changed. It resulted in bit variables becoming
10998 global, which is not permitted in PIC 14 assembly output.
11000 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11002 * doc/sdccman.lyx: various additions and updates. Rearranged sections
11004 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11006 Z80 and MCS51 linkers complaint if a public symbol is defined
11007 in more than one library module:
11011 * as/mcs51/Makefile.in
11013 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11015 A few small changes that speed up the peephole optimizer.
11019 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11021 Try to make the peephole optimizer smarter by maintaining
11022 an association between the assembly source code and the
11023 iCodes that originated them. Put this information to use
11024 with a new peephole rule condition "notVolatile" so that
11025 the rules can be aggressive yet still safe.
11030 * src/mcs51/peeph.def
11032 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11036 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11037 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11038 if the left or right operand symbols have the accuse flag set.
11040 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11042 Changed the type of the result of the ! (NOT) operator to char;
11043 previously it returned the same type as the source. This allows
11044 us to eliminate all the genFloatNot functions (all of its target
11045 implementations were very buggy) since !float can use the same
11048 * src/SDCCicode.c (ast2iCode): ! returns char
11049 * src/mcs51/gen.c (genNot, genNotFloat),
11050 * src/ds390/gen.c (genNot, genNotFloat),
11051 * src/z80/gen.c (genNot, genNotFloat),
11052 * src/pic/gen.c (genNot, genNotFloat),
11053 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
11055 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
11057 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11058 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11059 during interrupts. Ensure WSAVE is located at a shared bank address.
11060 2. Fixed page selection in some places
11061 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11062 the registers name strings.
11063 4. Fixed "signed / unsigned compare" compiler warnings.
11064 5. The PIC port manages its own allocation of the general purpose
11065 registers, but makes no attempt to reuse them. As a result when
11066 compiling it soon runs out of general purpose registers. Some
11067 additional code was added to the files pcode.c and device.c to walk
11068 through the function call tree and rename the registers so that they
11078 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11079 genPlus() & genMinus() when the result is the same as left or right
11081 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11085 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11087 Made bitfield a distinct type from bit so that bitfields
11088 convert as per ANSI C and bits retain their traditional
11089 boolean style behaviour. Implemented bitfield support in
11097 * src/ds390/gen.c: bit v bitfield split
11098 * src/z80/gen.c: New support for bitfields
11099 * support/regression/tests/bitfields.c: reenabled z80,
11102 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11104 Rules 246.x, 247.x relate to bitfields, the others speed up
11105 access to xdata mapped I/O devices.
11107 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11109 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11111 Cleaned up genPackBits and genUnpackBits and added two helper
11112 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11113 for literal assignments in genPackBits (thanks to Frieder for
11119 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11121 Fixed bug #748310 (pointer to function type mishandled when the
11122 function name is omitted). Also fixed a SIGSEGV when a function
11123 attribute (reentrant, etc) is used on a non-function or on a
11124 function but misplaced before the parameter list.
11126 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11128 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11129 * support/Util/SDCCerr.h,
11130 * support/Util/SDCCerr.c: Added func attr misuse error msg
11132 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11134 Fixed bug #787649 by anonymous
11135 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11136 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11138 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11140 Fixed numerous bitfield problems.
11142 * src/SDCC.y: More bitfield related error checking

11149 * support/regression/tests/bitfields.c: tests added
11151 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11153 Made the constant following the "interrupt" keyword optional. If
11154 omitted, the function will not automatically be given an entry
11155 in the interrupt vector table (similar to #pragma NOIV, but
11156 less syntacticly kludgy). The interrupt number is also now
11157 range checked. Also fixed a bug in the high order bit example
11164 * support/Util/SDCCerr.c
11165 * support/Util/SDCCerr.h
11168 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11171 * src/SDCCicode.c (operandOperation): rewritten some ops
11172 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11173 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11175 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11176 be re-activated by defining REDUCE_LITERALS)
11177 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11178 unsigned, but are signed by default
11179 * src/SDCCval.c (constVal): rearranged
11180 * src/SDCCval.c (valMod): preliminary fix
11181 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11221 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11222 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11223 constants are unsigned; added recognition of "u" flag for unsigned
11224 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11225 * src/SDCCval.c (valDiv, valMod): fixed signdness
11226 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
11227 signedness of modulo, left and right shift

11633 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
11634 the regression tests I'm not brave enough to enable 245.b, 245.c
11635 * doc/sdccman.lyx: added latex preamble for hyperref package.
11636 Using pdflatex this will give you a hyperlinked pdf file with
11637 bookmarks. (prepend '%' before /usepackage if this breaks something)

11677 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
11678 it can be defined with CFLAGS when running configure
11679 * src/SDCCmain.c: fixed compiling + linking with object files
11681 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

11686 * src/SDCCmain.c: linkOptions is changed to set *,
11687 added if/endif conditional macros to remove options help
11688 messages from optionsTable when a port is not configured, added
11689 support for the PIc16 port in the ports table, when executing
11690 the compiler with no port specified on command line, a default
11691 port is selected with the new macro DEFAULT_PORT which is
11692 defined in port.h, in setDefaultOptions() linkOptions is removed
11693 from initialization assignment, since now it is a set,
11694 parseCmdLine uses setParseWithComma for linkOptions, in
11695 linkEdit() linkOptions are accessed with new function indexSet()
11696 which returns the i'th item of a set variable. See SDCCset.c, in
11697 linkEdit() when calling buildCmdLine(), added linkOptions as
11698 last argument. Now users can pass arguments to gplink via the
11699 -Wl option, main() uses pic16glue() to glue up pic16 programs
11700 * src/SDCCpeeph.c: various changes to support pic16
11701 * src/SDCCset.c: added function void *indexSet(set *, int) to

11711 * src/pic16/glue.c: commented out some error producing lines
11712 * src/pic16/main.c: __config directives are commented out to stop
11713 gpasm complaining and test the linkage with gplink, _linkCmd and
11714 _asmCmd changed to be more gplink and gpasm friendly
11715 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11716 produced an error when parsed, peep rule 12 is added to utilize
11717 movff, but it is commented out since the pCode does not support
11718 yet a command with 2 address arguments
11720 2003-05-18 <johan AT balder>
11722 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12786 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12787 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12788 following files to include the previous two files: aslink.dsp,
12789 Makefile.aslink, Makefile.bcc, and Makefile.in.
12791 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12792 .adb instead of .cdb
12794 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12796 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12797 value from option --iram-size.
12799 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12801 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12804 2002-09-18 <wiml AT hhhh.org>
12806 * SDCClrange.h: exposed setFromRange() and setToRange()
12807 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12808 packRegsForAccUse() (bug 542397)
12809 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12810 multiple times and emitting the fetch operations more than once
12811 added aopGetUsesAcc() function to allow binary operators to
12812 fetch their operands in the correct order; made genMinus() emit
12813 compact code for X = LITERAL - Y
12815 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12816 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12817 sprintf() in line 1267.
12819 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12820 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12823 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12824 Changes to aslink (All the changes are marked with 'JCF'):
12826 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12829 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12830 area BSEG. Also moves, if possible, the DATA area down into the internal
12831 ram so more space is available.
12833 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12836 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12837 not bytes. Function summary() which creates a memory usage summary
12838 file with extension .mem. Reports of overlaping stack and small stack
12839 size. If the space for the stack is less than 16 bytes aslink trows a
12842 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12843 the 8051. Option 'y' for memory summary output file.
12845 Changes to sdcc (All the changes are marked with 'JCF'):
12847 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12849 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12850 overlaying area for it (uses RegBankUsed[4]).
12852 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12853 bank zero as used by default. By default aslink locates the stack
12854 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12855 the creation of the .mem file. Delegates the allocation of data area
12856 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12857 the begining of the stack area to aslink.
12859 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12860 glue() in SDCCglue.c creates an area for it.
12862 2002-09-03 Borut Razem <borut.razem AT siol.net>
12863 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12864 sdcc/src/pic/glue.c:
12865 introduced atexit() handler for teporay files removal in case of
12866 errors, assertions, ...
12868 2002-08-29 Borut Razem <borut.razem AT siol.net>
12869 * sdcc/support/cpp2/auto-host_vc_in.h:
12870 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12871 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12872 Maybe there is a similar problem with BORLANDC? It should be checked!
12874 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12875 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12876 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12877 was not executed, and the compiler (cl) launched a warning:
12878 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12880 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12881 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12883 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12884 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12886 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12887 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12888 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12889 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12890 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12891 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12892 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12893 - added Release configuration in VS projects
12894 - review of compiler an linker options
12895 - VC .exe files are generated in bin_vc directory, not to interfere
12896 with binaries generated from other projects (cygwin, mingw, bcc ...)
12898 * sdcc/src/yacc.dsp: added
12900 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12901 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12902 and insert the version number definitions from .version
12904 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12906 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12907 added - genarate auto-host.h using auto-host_vc_in.h as template
12910 removed from CVS, generated automatically
12912 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12913 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12915 2002-08-11 Borut Razem <borut.razem AT siol.net>
12916 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12918 2002-08-10 Borut Razem <borut.razem AT siol.net>
12919 * src/SDCCmain.c (main):
12920 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12921 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12922 The consequence was that some temporary files were not removed.
12925 unification of code in functions tempfilename() and tempfile():
12926 function tempnam() is defined in Visual Studio 6.0 and .NET
12928 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12930 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12931 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12932 - removed compiler command line option /WX: Treats all warnings as errors
12933 - update a list of source files, included into the project
12935 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12936 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12937 changed project type to Generic Project so that can be correcly converted to VS.NET project
12939 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12941 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12943 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12945 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12946 added return 0 statements after assert() to make compiler happy
12948 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12949 added newline in the def file to keep MSC compiler satisfied
12951 * sdcc/src/z80/gen.c:
12952 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12953 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12954 - solved MSC error in function aopDump()
12956 * sdcc_vc.h: define PREFIX as "\\sdcc"
12958 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12959 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12962 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12963 - Rewrote the register banking algorithm.
12964 - Added pCode live-range analysis to registers (for now, only non-used and
12965 singly-used registers optimized away)
12967 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12969 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

12992 * src/z80/main.c: Added force callee saves for jaune.
12994 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
12996 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12998 2002-03-28 Johan Knol <johan AT balder>
13000 * src/SDCCval.c: fixed bug #532436
13002 2002-03-14 Scott Dattalo <scott AT dattalo.com>
13004 Added "char *Processor" field to the port structure.
13007 Added -p option. Allows port dependent processor to be specified.
13010 Initialized the new field char *Processor field to NULL in all ports
13013 Compiler generated registers for interrupt context saving
13014 were not getting allocated.
13016 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
13019 Fixed left shift. Will promote the left side of a left shift
13020 if a) left shifting more than size of operand or b) when assigned
13021 to something size > size of left side
13023 2002-03-14 Scott Dattalo <scott AT dattalo.com>

13027 analysis is restructured. ...
13029 * src/pic/device.h:
13032 * src/pic/device.c:
13033 Added. device.c is a PIC port hack to accomodate variations

13131 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13133 * sdcc/src/SDCCloop.c:
13134 Previous fix was not good. basic blocks that have "break" or "return" are
13135 not really partof a loop , but live ranges used in these blocks should
13136 be live thru the entire loop, so set partOfLoop but don't add them to
13139 2002-02-21 <johan AT FRIJA>
13141 * src/SDCCcse.c: fixed bug #514308
13143 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
13146 Fixed BUG #519583. If a conditional block ended in a return/break
