2802 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2804 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2805 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2807 One basic decision: e.g. src/clean.mk includes further files. In order
2808 to make this work there are two solutions:
2809 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2810 run configure on them. This way they can use
2811 'include $(srcdir)/port-clean.mk'
2812 - always include clean.mk by the Makefile at the same level. To avoid
2813 that `make clean` tries to include and build Makefile.dep the
2814 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2815 implemented, because now even `make uninstall` doesn't create
2816 Makefile.in. clean.mk could be eliminated by pasting it in
2819 * debugger/mcs51/Makefile.in: build own objects from library sources
2820 (SLIB, SDCC) in current directory
2822 * configure, configure.in: renamed --disable-device-lib-build in
2823 --disable-device-lib; added --enable-doc, the required tools are
2824 searched by configure; added result message; the toolchain for the
2825 belonging ports are now only built, if the port is enabled.
2827 * support/regression/*: all output is written in directory gen, because
2828 the fwk and ports directories don't livet in the build tree using vpath
2830 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2831 --disable-device-lib, added --enable-doc, added section VPATH
2833 * sim/ucsim/configure.in,
2834 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2835 z80 are enabled by default
2837 2006-04-24 Raphael Neider <rneider AT web.de>
2839 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2840 to config word, "pic14_"-prefixed some extern functions
2841 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2842 config word has been found
2843 * src/pic/device.h: added prototypes
2844 * src/pic/pcode.c: added "pic14_"-prefix where needed
2845 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2847 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2861 fixes #1469504 and #1474602,
2862 (pCodeRegOptimizeRegUsage): fixed typo in comment

3085 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
3087 * src/mcs51/gen.c (genCall): fixed bug 1457608
3089 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

3094 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
3096 * src/SDCCpeeph.c (operandsLiteral): new, added,

3107 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
3108 implemented patch 1120823 Thanks to Willy De la Court (normal
3109 interrupts need an interrupt number now if they are made critical),
3110 and enabled nesting of critical functions though not for gbz80
3111 (genCritical, genEndCritical): added functions
3112 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3113 * src/z80/mappings.i: added "ei" to all mappings
3115 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3117 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
3118 submitted by the Debian SDCC maintainer Aurelien Jarno:
3119 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
3120 archive with gcc 4.1 on mips and wrote the patch"
3122 2006-03-16 Raphael Neider <rneider AT web.de>
3124 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
3125 the left operand is shorter than the result (c* = lit-c* + int),
3127 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3130 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3132 * src/.version: increased version number to 2.5.5
3133 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3134 linking is done manually in pic16 port's _linkEdit,
3135 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3136 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3137 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3138 allocate asmop as AOP_ACC,
3139 (aopForRemat): added parameter 'bool result' in function declaration,
3140 (pic16_aopGet): return AOP_ACC when accessing WREG,
3141 (pic16_popGetTempReg): minor modification,
3142 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
3143 'pic16_allocWithIdx',
3144 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
3145 calling function in absolute addresses,
3146 (genAssign): take into account AOP_ACC asmop,
3147 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
3148 * src/pic16/pcoderegs.c: some debug functions and lines added,
3149 * src/pic16/ralloc.c (decodeRegType): added but commented out,
3150 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
3152 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3153 call to allocReg, not by manually allocating a new one,
3154 (pic16_assignRegisters): now before going through the register
3155 allocating functions mark all registers as free. This eliminates some
3156 side effects resulting from peephole parser done earlier in the backbone
3158 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
3160 * src/SDCCicode.c (geniCodeLogic),

3179 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
3180 (aopForSym, aopOp): increment asmop.allocated if reused,
3181 (freeAsmop): decrement asmop.allocated and check for zero instead of
3183 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
3184 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
3185 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

3208 2006-03-06 Borut Razem <borut.razem AT siol.net>
3210 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3211 made the linker quiet
3213 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
3215 * src/pic16/gen.c (genPcall): fixed bug #1443644
3216 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3217 which dumps before the function entry point a data byte which represents
3218 the number of the local variables used by the specified function, added
3219 'xinst' for initial support for Extended Instruction Support,
3220 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3221 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3222 port->fun_prefix anymore (may change later),
3223 (genFunction, genEndFunction): do not store/restore local registers for
3224 _main (this should take care the --main-return command line option in
3226 (genOr): removed some legacy pic-port instructions,
3227 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3228 performing operations with SFR's causes data to be written more than
3229 once to each SFR. Perhaps SFRs should be handled in special cases...
3230 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3232 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3233 into account for stack starting position,
3234 (struct OPTIONS pic16_optionsTable): added command line argument
3235 --extended or -y for Extended Instruction Support,
3236 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3237 (deassignLRs): *** perhaps the most important change, old 'for' code
3238 (commented out for reference), didn't account for some registers which
3239 were left marked 'not free' after a pointer operation. The change
3240 reduces register usage a lot in some cases
3242 2006-03-04 Borut Razem <borut.razem AT siol.net>
3244 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

5566 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
5567 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
5568 immedDom() returning wrong block; probably fixes bug #1160833)
5570 2005-03-20 Borut Razem <borut.razem AT siol.net>
5572 * support/scripts/inc2h.pl: WIN32 port
5574 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
5576 * device/lib/makefile.in: added abs.c and labs.c
5578 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
5580 * device/include/stdint.h: added
5581 * device/lib/abs.c: added
5582 * device/lib/labs.c: added
5583 * device/include/stdlib.h: added abs() and labs() prototypes
5584 * device/lib/libsdcc.lib: added abs and labs
5585 * device/include/float.h,
5586 * device/lib/_fsmul.c,
5587 * device/lib/printf_fast.c,
5588 * device/lib/printf_tiny.c: updated comments
5590 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5592 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
5595 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5597 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
5598 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5600 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5602 * device/lib/printf_large.c: removed inline assembly for portability and
5603 readability. Use printf_fast if speed or size are more important.
5604 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5605 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5607 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5609 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5610 prevent compiler warning
5612 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5614 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5615 moved to level 0 and declared as static. Also they are explicit
5616 placed in access bank. This was necessery because some times they
5617 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5618 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5619 optimizations. Currently only compare to unsigned char is implemented,
5620 * src/pic16/gen.c: added fReturnIdx array,
5621 * (struct resolvedIfx) is moved to gen.h and made public,
5622 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5623 * (aopForSym): added an optimization to directly store in stack of
5624 the operand of a SEND iCode,
5625 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5626 but as registers instead (AOP_REG) using the fReturnIdx array,
5627 * (pic16_freeAsmop): remove the freed register from the
5628 _G.sregsAlloc field,
5629 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5630 a compare of 'WREG',
5631 * (pic16_popGetTempRegCond): changed function prototype, now
5632 function takes also a bitVector argument v which holds the current
5633 set of registers that are allocated for stack access by aopForSym,
5634 registers allocated in aopForSym for accessing stack symbols are not
5635 any more part of the functions usedRegs field,
5636 * (genCall): some times aopOp is called for a stack variable to be
5637 send, aopForSym might perform the push, if this is true make sure
5638 that genCall doesn't push the variable twice by testing _G.resDirect,
5639 * (genFunction): changed testing for unspecified interrupt number
5640 from 256 to INTNO_UNSPEC,
5641 * modified selection scheme of frame pointer generation. Previously
5642 if function did use local registers a frame pointer was generated,
5643 now a frame pointer is generated only if function has arguments
5644 (that need PLUSW2 register access), or has stack arguments, or the
5645 compiler is not instructed to omit the frame pointer,
5646 * (genEndFunction): before restoring local registers that were saved
5647 in the function preamble, also restore the registers that *might*
5648 have been allocated for stack access,
5649 * (genRet): removed some old comments,
5650 * (genCmp, the active (RN's) version): added a call to the
5651 pic16_genCmp_special function to perform the compare with a more
5652 robust and optimized way,
5653 * (genInline): a feature has been added in inline code generation,
5654 which allows a wildcard variable substitution when writing inline
5655 assembly. Code is incomplete and experimental therefore undocumented,
5656 * (genCast): changed order of aopOp for result and right to allow
5657 aopForSym to directly load the result if possible,
5658 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5659 perform an optimized compare on some selected special occasions,
5660 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5661 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5662 generate an IVT any more,
5663 * src/pic16/main.c (pic16_optionsTable): added command line option
5665 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5666 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5668 * src/pic16/NOTES: Raphael Neider added in list of active developers
5669 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5670 jumptable_end to prevent bug #,
5671 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5672 inCond and outCond fields,
5673 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5674 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5675 turn off register spilling,
5676 * (packRegsForOneUse): synced with other ports' versions although it
5677 is not used currently,
5678 * (pic16_packRegisters): added an optimization while reading
5679 structure bitfields, some registers may be saved (malloc code is
5680 decreased by 80 bytes)
5682 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5684 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5685 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5686 this can be optimized more?
5688 2005-03-10 Raphael Neider <rneider AT web.de>
5690 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5691 genNearPointerGet): (hopefully) fixed access to bitfields via
5692 pointers (p->bitN = x; and x = p->bitN; failed)
5694 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5735 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5737 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
5738 to keep the correct label reference count when adding/removing references
5739 to labels. A peephole file using this is appended to patch #1144962.

5881 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5882 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5883 this might fix SIGSEGVs on MinGW...
5884 * src/SDCCopt.c (killDeadCode): restored original behaviour
5885 (volatile operands might get thrown away though)
5887 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

5972 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
5973 used uninitialized in some cases)

5975 copy the third byte from the int -- now assumes 0x80 (data memory)
5976 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
5977 operands (genAddLit expects the iCode's operands to swapped as
5978 well), fixed leftover bytes (crashed for short left operands)

6327 generated for switch statements. For now you need to set the
6328 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6329 Now 4 algorithms for mcs51 jumptable generation are used:
6330 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

6362 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6364 * added libc directory. The current version of LibC contains string
6365 functions, ctype functions and macros and some functions of the
6366 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6367 be extensively tested in the future. Standard disclaimer here.
6368 Library is not automatically build yet. But one can build it by

6380 * (pic16_storeForReturn): optimized return of 0,
6381 * (genCmp): experimental code for new genCmp which uses PIC18's
6382 special compare&skip instructions. Initial tests fail some times
6383 with variables grater than 1 byte in size, so new code is disabled,
6384 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6386 * (genCast): began a fix to optimize the casting of a bit to another
6387 bit, now assigning a bitfield to another bitfield will fail, sorry,

6396 and 1 for banking instruction,
6397 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
6398 caused stop processing pCodes after a inline assembly block,
6399 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

6401 registers when it shouldn't,
6402 * src/pic16/ralloc.c (allocReg): add preliminary support for
6403 supporting a limited set of temporary registers,
6405 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6407 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
6408 genDataPointerSet): ensure assignments always copy in MSB to LSB
6410 (loadRegFromAop): recognize CLRH optimization,
6411 (genFunction): optimize RECEIVE iCodes in reentrant functions
6413 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6415 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

9410 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9412 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9413 loaded with the linker search paths (-L arguments) and the libraries
9414 to be linked with the current source (-l arguments). Changes
9415 currently will affect only the pic16 port.
9416 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9417 include path the port specific paths and port specific libraries,
9418 * gplink command now contains the $3 argument,
9419 * src/pic16/device.h,
9420 * src/pic16/device.c,: structure PIC_device is made public and
9421 renamed to PIC16_device, the same for variable Pics which is renamed

9436 Documenting changes from previous commits.
9437 * configure.in (version 1.56),
9438 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9439 when generating output files to configure the pic16 library,
9440 but now I've commented it out, since gputils aren't installed in the
9441 SF compile farm, so library won't compile
9443 * device/lib/Makefile.in (version 1.56): initially I've added in
9444 target 'all' the prerequestive 'model-pic16' so it compiled the
9445 pic16 library, but now I've commented it out for the same reasons
9447 * added targets 'model-pic16' and 'objects-pic16' to compile the
9449 * added target 'port-specific-objects-pic16' to handle the
9450 generated libraries and copy them into the build/ directory
9451 * added target 'clean-intermediate-pic16' to clean intermediate
9452 files into pic16 directory
9453 * in target 'installdirs' added line to create directory pic16 in
9454 the installation path
9456 * device/include/Makefile.in (version 1.11): in target 'install'
9457 added lines to copy all header files to installation path,
9458 * in target 'installdirs' added line create directory for pic16
9459 headers in the installation path

9474 * src/z80/main.c (_parseOptions): fixed the portmode= command line
9475 option so that it actually works. Made it specific to the z80, since
9476 the gbz80 doesn't have these kinds of I/O ports.
9478 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9480 * device/include/z180.h,

9504 via literal number. The symbol is placed in the corresponding
9505 position of the data ram
9506 * (pic16_dump_section): relocatable and absolute uninitialized
9507 data are now emitted in sorted order to reduce section naming,
9508 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
9509 weren't marked as being in the access bank,
9511 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
9513 Added portion of GNU PIC Library under the directory
9514 device/include/pic16 and device/lib/pic16. These files
9515 contain the declarations of SFRs for the PIC18Fxx2 devices.
9516 The directory is initialized via configure from toplevel.

9527 2004-01-12 Borut Razem <borut.razem AT siol.net>
9529 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
9530 doc/sdccman.lyx: upper case pragmas are deprecated
9532 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
9534 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
9535 in simpler and even better code
9537 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
9539 * src/SDCCicode.c (operandOperation): fixed bug #874819

9541 char foo (unsigned long ul) { return ul > 0; }
9543 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9545 * doc/sdccman.lyx: Moved and added some sections, small changes
9546 all over. Telling LaTeX to be less strict with word spacing
9547 to better keep the right margin. Changed some notes about
9548 maintainance of the ports in section 3.2.1 - is it OK like this?
9550 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
9552 SDCC source changes:
9553 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

9559 processor registers declared internally by the port are emitted in
9560 the translation as equates,
9561 * src/pic16/gen.c: inline code is passed unprocessed to the

9587 UPPER for immediate operands,
9588 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
9590 * src/pic16/peeph.def: all peepholes with movff are commented out,
9591 because there is a problem in the pcode peep optimizer,
9592 * src/pic16/ralloc.c: the register allocator can now reuse local

9702 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9704 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9705 (default behaviour).
9707 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9709 A python script to validate compiler diagnostic messages. It can be
9710 used to verify that sdcc complains about bad c source code and
9711 gives a good location of the error.
9712 * support/valdiag/Makefile,
9713 * support/valdiag/valdiag.py,
9714 * support/valdiag/tests/*

9729 * src/common.h: added ifndef/define/endif macros
9730 around the header file.
9731 Bug reported from Jesus Calvino-Fraga
9733 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9735 * sdcc.spec: updated
9736 * device/include/Makefile.in: don't install CVS directories
9737 * device/lib/Makefile.in: added removal of CVS directories after install
9738 * doc/Makefile: fixed install, added local_icons
9739 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9740 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9741 * src/ds390/gen.c (genRightShift): fixed bug #870788
9742 * src/SDCCast.c (decorateType): fixed bug #870781
9744 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9746 PIC16 port related changes:
9747 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9748 added variable stackPos,
9750 * gen.c: genCall, assignResultValue: added support for
9751 pushing/retrieving function parameters to/from stack,
9752 genFunction,genEndFunction: setup stack frame for the
9754 genAddrOf: will be changed according to bug 863624
9756 * added files genutils.c and genutils.h which contain gen*
9757 debugged and optimised functions extracted from gen.c
9759 * glue.c: added variable 'externs' which holds extern symbols,
9760 pic16emitRegularMap: is modified to properly handle relocatable
9761 symbols under the new scheme,
9762 pic16createInterruptVect: is modified
9763 pic16printPublics: is modified to emit 'global' assembler directives,
9764 added pic16_printExterns to print extern symbols,
9765 pic16glue: initializes stack/frame pointer in the beginning of
9766 the assembly output. Temporary hack, will be corrected later,
9767 because gplink yet does not support stack and SDCC does not
9768 yet support a type of crt0.o object to create the final binary.
9770 * Removed many lines that contain 8051 legacy code.
9771 * The code is finally placed under a 'code' directive.
9772 * Added port specific options.
9774 * _process_pragma: simplified since now we do not need *special*
9775 include file to define SFR registers. But a separate header
9776 will be needed. This will be developed later.
9777 * _pic16_parseOptions: added, parses port specific options:
9778 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9779 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9780 --preplace-udata-with=
9782 * _pic16_setDefaultOptions: modified to initialize section names,
9783 but hack is temporarly out of order since it needs improvement.
9784 * _pic16_genAssemblerPreamble: configuration words are emitted by
9785 their address instead of their name. This part is incomplete and
9786 supports only the 18Fxx2 devices. Other devices will emit an error
9787 during assembly since they do not contain the same set of config
9789 * _pic16_genIVT: is modified,
9791 * pcode.c: added definitions for some hardware registers that are needed
9793 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9794 All PCI entries are updated. Now LFSR is supported.
9795 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9796 * added pic16_newpCodeOpLit2 to support instructions with
9797 two literal arguments
9798 * pic16_pCode2str: corrected code that emits assembler instructions
9799 with two literal operands and those that have an access bit modifier
9800 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9801 this fixes a bug which caused some labels to be lost, when an
9802 assembler directive was added, i.e. banksel,
9803 * pic16_FixRegisterBanking: improved logic that causes the insertion
9805 * InlineFunction: functions that are called once, are not any more
9806 inlined. This can be a port option in the future,
9808 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9810 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9811 hold the corresponding uninitialized symbols,
9812 * pic16_allocProcessorRegister: registers have explicit marked the
9814 * pic16_allocInternalRegister: registers are explicit marked as
9816 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9817 processing list, so bit registers were lost,
9820 * ralloc.h: added field 'accessBank' and original symbol operand
9821 in register definition,
9822 * removed the field isMapped from register definition,
9824 ** Several functions have been removed from various sources:
9825 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9826 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9827 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9828 pic16_assignRelocatableRegisters
9830 ** others have been introduced:
9831 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9832 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9834 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9836 * support/scripts/inc2h.pl: changed definition of BIT_AT
9837 to emit 'sbit at' instead of 'bit at'. This was a request.
9839 PIC16 port related preliminary changes:
9840 * gen.c: prefixed function popRegFromString with
9841 pic16_ and all references to it corrected
9842 * pcode.c: all pic16_pc_* hardware registers prefixed
9843 with underscore (_),
9844 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9845 * ralloc.c: newReg(): when register is REG_SFR then
9846 set address to rIdx,
9847 pic16_allocProcessorRegister(): marks register wasUsed=0
9848 pic16_writeUsedRegs(): added a call to assign processor
9849 registers via pic16_assignFixedRegisters
9851 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9853 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9854 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9855 variables in unused register banks. Also the SSEG is placed
9856 wherever there is enough space for it, and IDATA can be anywhere
9857 in internal RAM. For now compile using -Wl-Y[stack_size].
9858 The mem file is different for this option as well, since it
9859 makes no sense of talking about DSEG lenght.
9861 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9863 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9864 in certain cases, e.g. when ROM assignment, patch provided
9865 from Albert den Haan.
9867 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10010 * src/mcs51/peephole.def,
10011 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
10012 (allows non-interrupt and interrupt code to safely compete for a resource

10752 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10753 support for standard C idiom of memory mapped variables; for
10754 example, *((xdata int*)0x1234) = 1 is now internally equivalent

10773 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10775 Fixed bug #621531 (const & volatile confusion in the type chain).
10776 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10777 refer to the const or volatile state of the pointer itself.
10789 * src/pic16/ralloc.c

10856 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10857 iCode properly now. Use getSize instead of nRegs since a & b
10858 aren't part of the nRegs tally.
10860 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10862 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10872 copied from genNearPointerSet()
10873 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10874 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10875 If they pop r0/r1 they must be called in the opposite order than aopOp().
10876 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10877 (resp. --stack-auto), prepared for --xstack
10879 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

10888 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10890 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10891 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10892 type for bits was changed. It resulted in bit variables becoming
10893 global, which is not permitted in PIC 14 assembly output.
10895 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10897 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10899 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10901 Z80 and MCS51 linkers complaint if a public symbol is defined
10902 in more than one library module:

10908 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10910 A few small changes that speed up the peephole optimizer.
10914 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10916 Try to make the peephole optimizer smarter by maintaining
10917 an association between the assembly source code and the
10918 iCodes that originated them. Put this information to use
10919 with a new peephole rule condition "notVolatile" so that
10920 the rules can be aggressive yet still safe.
10925 * src/mcs51/peeph.def
10927 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10931 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10932 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10933 if the left or right operand symbols have the accuse flag set.
10935 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10937 Changed the type of the result of the ! (NOT) operator to char;
10938 previously it returned the same type as the source. This allows
10939 us to eliminate all the genFloatNot functions (all of its target
10940 implementations were very buggy) since !float can use the same
10943 * src/SDCCicode.c (ast2iCode): ! returns char
10944 * src/mcs51/gen.c (genNot, genNotFloat),
10945 * src/ds390/gen.c (genNot, genNotFloat),
10946 * src/z80/gen.c (genNot, genNotFloat),

10952 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10953 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10954 during interrupts. Ensure WSAVE is located at a shared bank address.
10955 2. Fixed page selection in some places
10956 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10957 the registers name strings.
10958 4. Fixed "signed / unsigned compare" compiler warnings.
10959 5. The PIC port manages its own allocation of the general purpose
10960 registers, but makes no attempt to reuse them. As a result when
10961 compiling it soon runs out of general purpose registers. Some
10962 additional code was added to the files pcode.c and device.c to walk
10963 through the function call tree and rename the registers so that they
10973 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10974 genPlus() & genMinus() when the result is the same as left or right

10982 Made bitfield a distinct type from bit so that bitfields
10983 convert as per ANSI C and bits retain their traditional
10984 boolean style behaviour. Implemented bitfield support in
10992 * src/ds390/gen.c: bit v bitfield split
10993 * src/z80/gen.c: New support for bitfields
10994 * support/regression/tests/bitfields.c: reenabled z80,
10997 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10999 Rules 246.x, 247.x relate to bitfields, the others speed up
11000 access to xdata mapped I/O devices.

11004 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11006 Cleaned up genPackBits and genUnpackBits and added two helper
11007 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11008 for literal assignments in genPackBits (thanks to Frieder for
11014 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11016 Fixed bug #748310 (pointer to function type mishandled when the
11017 function name is omitted). Also fixed a SIGSEGV when a function
11018 attribute (reentrant, etc) is used on a non-function or on a
11019 function but misplaced before the parameter list.

11046 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11048 Made the constant following the "interrupt" keyword optional. If
11049 omitted, the function will not automatically be given an entry
11050 in the interrupt vector table (similar to #pragma NOIV, but
11051 less syntacticly kludgy). The interrupt number is also now
11052 range checked. Also fixed a bug in the high order bit example

11528 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
11529 the regression tests I'm not brave enough to enable 245.b, 245.c
11530 * doc/sdccman.lyx: added latex preamble for hyperref package.
11531 Using pdflatex this will give you a hyperlinked pdf file with

11582 added if/endif conditional macros to remove options help
11583 messages from optionsTable when a port is not configured, added
11584 support for the PIc16 port in the ports table, when executing
11585 the compiler with no port specified on command line, a default
11586 port is selected with the new macro DEFAULT_PORT which is
11587 defined in port.h, in setDefaultOptions() linkOptions is removed
11588 from initialization assignment, since now it is a set,
11589 parseCmdLine uses setParseWithComma for linkOptions, in
11590 linkEdit() linkOptions are accessed with new function indexSet()
11591 which returns the i'th item of a set variable. See SDCCset.c, in
11592 linkEdit() when calling buildCmdLine(), added linkOptions as
11593 last argument. Now users can pass arguments to gplink via the
11594 -Wl option, main() uses pic16glue() to glue up pic16 programs

11606 * src/pic16/glue.c: commented out some error producing lines
11607 * src/pic16/main.c: __config directives are commented out to stop
11608 gpasm complaining and test the linkage with gplink, _linkCmd and
11609 _asmCmd changed to be more gplink and gpasm friendly
11610 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11611 produced an error when parsed, peep rule 12 is added to utilize
11612 movff, but it is commented out since the pCode does not support
11613 yet a command with 2 address arguments
11615 2003-05-18 <johan AT balder>
11617 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12678 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12680 * in /sdcc/as/mcs51/ changed these files in order to create an
12681 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12682 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12683 following files to include the previous two files: aslink.dsp,
12684 Makefile.aslink, Makefile.bcc, and Makefile.in.
12686 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12687 .adb instead of .cdb
12689 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12691 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12692 value from option --iram-size.
12694 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12696 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12699 2002-09-18 <wiml AT hhhh.org>
12701 * SDCClrange.h: exposed setFromRange() and setToRange()
12702 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12703 packRegsForAccUse() (bug 542397)
12704 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12705 multiple times and emitting the fetch operations more than once
12706 added aopGetUsesAcc() function to allow binary operators to
12707 fetch their operands in the correct order; made genMinus() emit
12708 compact code for X = LITERAL - Y
12710 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12711 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12712 sprintf() in line 1267.
12714 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12715 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12718 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12719 Changes to aslink (All the changes are marked with 'JCF'):
12721 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12724 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12725 area BSEG. Also moves, if possible, the DATA area down into the internal
12726 ram so more space is available.
12728 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12731 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12732 not bytes. Function summary() which creates a memory usage summary
12733 file with extension .mem. Reports of overlaping stack and small stack
12734 size. If the space for the stack is less than 16 bytes aslink trows a
12737 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12738 the 8051. Option 'y' for memory summary output file.
12740 Changes to sdcc (All the changes are marked with 'JCF'):
12742 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12744 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12745 overlaying area for it (uses RegBankUsed[4]).
12747 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12748 bank zero as used by default. By default aslink locates the stack
12749 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12750 the creation of the .mem file. Delegates the allocation of data area
12751 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12752 the begining of the stack area to aslink.
12754 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12755 glue() in SDCCglue.c creates an area for it.
12757 2002-09-03 Borut Razem <borut.razem AT siol.net>
12758 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12759 sdcc/src/pic/glue.c:
12760 introduced atexit() handler for teporay files removal in case of
12761 errors, assertions, ...
12763 2002-08-29 Borut Razem <borut.razem AT siol.net>
12764 * sdcc/support/cpp2/auto-host_vc_in.h:
12765 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12766 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12767 Maybe there is a similar problem with BORLANDC? It should be checked!
12769 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12770 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12771 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12772 was not executed, and the compiler (cl) launched a warning:
12773 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12775 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12776 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12778 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12779 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects

12787 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12788 - added Release configuration in VS projects
12789 - review of compiler an linker options
12790 - VC .exe files are generated in bin_vc directory, not to interfere
12791 with binaries generated from other projects (cygwin, mingw, bcc ...)
12793 * sdcc/src/yacc.dsp: added
12795 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12796 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12797 and insert the version number definitions from .version
12799 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12801 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12802 added - genarate auto-host.h using auto-host_vc_in.h as template
12805 removed from CVS, generated automatically
12807 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12808 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12810 2002-08-11 Borut Razem <borut.razem AT siol.net>
12811 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12813 2002-08-10 Borut Razem <borut.razem AT siol.net>
12814 * src/SDCCmain.c (main):
12815 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12816 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12817 The consequence was that some temporary files were not removed.
12820 unification of code in functions tempfilename() and tempfile():
12821 function tempnam() is defined in Visual Studio 6.0 and .NET
12823 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12825 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12826 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12827 - removed compiler command line option /WX: Treats all warnings as errors
12828 - update a list of source files, included into the project
12830 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12831 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12832 changed project type to Generic Project so that can be correcly converted to VS.NET project
12834 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12836 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

12840 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12841 added return 0 statements after assert() to make compiler happy
12843 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12844 added newline in the def file to keep MSC compiler satisfied
12846 * sdcc/src/z80/gen.c:
12847 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12848 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12849 - solved MSC error in function aopDump()
12851 * sdcc_vc.h: define PREFIX as "\\sdcc"
12853 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

13026 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13028 * sdcc/src/SDCCloop.c:
13029 Previous fix was not good. basic blocks that have "break" or "return" are
13030 not really partof a loop , but live ranges used in these blocks should
13031 be live thru the entire loop, so set partOfLoop but don't add them to
