781 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
783 Enabled VPATH feature: changed nearly all Makefiles (149 files).
784 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
786 One basic decision: e.g. src/clean.mk includes further files. In order
787 to make this work there are two solutions:
788 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
789 run configure on them. This way they can use
790 'include $(srcdir)/port-clean.mk'
791 - always include clean.mk by the Makefile at the same level. To avoid
792 that `make clean` tries to include and build Makefile.dep the
793 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
794 implemented, because now even `make uninstall` doesn't create
795 Makefile.in. clean.mk could be eliminated by pasting it in
798 * debugger/mcs51/Makefile.in: build own objects from library sources
799 (SLIB, SDCC) in current directory
801 * configure, configure.in: renamed --disable-device-lib-build in
802 --disable-device-lib; added --enable-doc, the required tools are
803 searched by configure; added result message; the toolchain for the
804 belonging ports are now only built, if the port is enabled.
806 * support/regression/*: all output is written in directory gen, because
807 the fwk and ports directories don't livet in the build tree using vpath
809 * doc/sdccman.lyx: renamed --disable-device-lib-build to
810 --disable-device-lib, added --enable-doc, added section VPATH
812 * sim/ucsim/configure.in,
813 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
814 z80 are enabled by default
816 2006-04-24 Raphael Neider <rneider AT web.de>
818 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
819 to config word, "pic14_"-prefixed some extern functions
820 (pic14_emitConfigWord): emit __config directive(s) if assignment to
821 config word has been found
822 * src/pic/device.h: added prototypes
823 * src/pic/pcode.c: added "pic14_"-prefix where needed
824 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
826 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
828 (pic14emitRegularMap): ignore config words,
829 (pic14createInterruptVect): moved generating __config directives away
830 (picglue): have __config directives emitted
832 2006-04-24 Borut Razem <borut.razem AT siol.net>
834 * doc/Makefile: sync with nightly build makefile

840 fixes #1469504 and #1474602,
841 (pCodeRegOptimizeRegUsage): fixed typo in comment
843 2006-04-24 Borut Razem <borut.razem AT siol.net>
845 * device/examples/main8051.c: deleted - it was removed from CVS

1087 implemented patch 1120823 Thanks to Willy De la Court (normal
1088 interrupts need an interrupt number now if they are made critical),
1089 and enabled nesting of critical functions though not for gbz80
1090 (genCritical, genEndCritical): added functions
1091 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1092 * src/z80/mappings.i: added "ei" to all mappings

1104 the left operand is shorter than the result (c* = lit-c* + int),
1106 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1109 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1111 * src/.version: increased version number to 2.5.5
1112 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1113 linking is done manually in pic16 port's _linkEdit,
1114 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1115 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1116 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1117 allocate asmop as AOP_ACC,
1118 (aopForRemat): added parameter 'bool result' in function declaration,
1119 (pic16_aopGet): return AOP_ACC when accessing WREG,
1120 (pic16_popGetTempReg): minor modification,

1131 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1132 call to allocReg, not by manually allocating a new one,
1133 (pic16_assignRegisters): now before going through the register
1134 allocating functions mark all registers as free. This eliminates some
1135 side effects resulting from peephole parser done earlier in the backbone
1137 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1195 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1196 which dumps before the function entry point a data byte which represents
1197 the number of the local variables used by the specified function, added
1198 'xinst' for initial support for Extended Instruction Support,
1199 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1200 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1201 port->fun_prefix anymore (may change later),
1202 (genFunction, genEndFunction): do not store/restore local registers for
1203 _main (this should take care the --main-return command line option in
1205 (genOr): removed some legacy pic-port instructions,
1206 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1207 performing operations with SFR's causes data to be written more than
1208 once to each SFR. Perhaps SFRs should be handled in special cases...
1209 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1211 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1212 into account for stack starting position,

1214 --extended or -y for Extended Instruction Support,
1215 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1216 (deassignLRs): *** perhaps the most important change, old 'for' code
1217 (commented out for reference), didn't account for some registers which
1218 were left marked 'not free' after a pointer operation. The change
1219 reduces register usage a lot in some cases

3483 if condition == CARRY)
3484 * (genCmp): adapted to new genSkipc semantics
3485 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
3486 on rIfx (genCmp was broken)
3488 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3490 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3491 * src/z80/main.c (_keywords[]),
3492 * src/SDCCglobal.h (struct options),
3494 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3495 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3496 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3497 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3498 always available in leading double underscore form. The C99 support is
3499 mostly missing, but it's a start.
3500 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3501 reserved identifier "__data".
3503 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3505 * src/mcs51/peeph.def: fixed bug 1170013

3513 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
3516 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3518 * src/port.h (struct PORT),

3549 2005-03-20 Borut Razem <borut.razem AT siol.net>
3551 * support/scripts/inc2h.pl: WIN32 port
3553 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3555 * device/lib/makefile.in: added abs.c and labs.c
3557 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3559 * device/include/stdint.h: added
3560 * device/lib/abs.c: added
3561 * device/lib/labs.c: added
3562 * device/include/stdlib.h: added abs() and labs() prototypes

3577 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3579 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3581 * device/lib/printf_large.c: removed inline assembly for portability and
3582 readability. Use printf_fast if speed or size are more important.
3583 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3584 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3586 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3588 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3589 prevent compiler warning
3591 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3593 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3594 moved to level 0 and declared as static. Also they are explicit
3595 placed in access bank. This was necessery because some times they
3596 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3597 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3598 optimizations. Currently only compare to unsigned char is implemented,
3599 * src/pic16/gen.c: added fReturnIdx array,
3600 * (struct resolvedIfx) is moved to gen.h and made public,
3601 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3602 * (aopForSym): added an optimization to directly store in stack of
3603 the operand of a SEND iCode,
3604 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3605 but as registers instead (AOP_REG) using the fReturnIdx array,
3606 * (pic16_freeAsmop): remove the freed register from the
3607 _G.sregsAlloc field,
3608 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3609 a compare of 'WREG',
3610 * (pic16_popGetTempRegCond): changed function prototype, now
3611 function takes also a bitVector argument v which holds the current
3612 set of registers that are allocated for stack access by aopForSym,
3613 registers allocated in aopForSym for accessing stack symbols are not
3614 any more part of the functions usedRegs field,
3615 * (genCall): some times aopOp is called for a stack variable to be
3616 send, aopForSym might perform the push, if this is true make sure
3617 that genCall doesn't push the variable twice by testing _G.resDirect,
3618 * (genFunction): changed testing for unspecified interrupt number
3619 from 256 to INTNO_UNSPEC,
3620 * modified selection scheme of frame pointer generation. Previously
3621 if function did use local registers a frame pointer was generated,
3622 now a frame pointer is generated only if function has arguments
3623 (that need PLUSW2 register access), or has stack arguments, or the
3624 compiler is not instructed to omit the frame pointer,
3625 * (genEndFunction): before restoring local registers that were saved
3626 in the function preamble, also restore the registers that *might*
3627 have been allocated for stack access,
3628 * (genRet): removed some old comments,
3629 * (genCmp, the active (RN's) version): added a call to the
3630 pic16_genCmp_special function to perform the compare with a more
3631 robust and optimized way,
3632 * (genInline): a feature has been added in inline code generation,
3633 which allows a wildcard variable substitution when writing inline
3634 assembly. Code is incomplete and experimental therefore undocumented,
3635 * (genCast): changed order of aopOp for result and right to allow
3636 aopForSym to directly load the result if possible,
3637 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3638 perform an optimized compare on some selected special occasions,
3639 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3640 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3641 generate an IVT any more,
3642 * src/pic16/main.c (pic16_optionsTable): added command line option
3644 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3645 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3647 * src/pic16/NOTES: Raphael Neider added in list of active developers
3648 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3649 jumptable_end to prevent bug #,
3650 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3651 inCond and outCond fields,
3652 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3653 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3654 turn off register spilling,
3655 * (packRegsForOneUse): synced with other ports' versions although it
3656 is not used currently,
3657 * (pic16_packRegisters): added an optimization while reading
3658 structure bitfields, some registers may be saved (malloc code is
3659 decreased by 80 bytes)
3661 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3663 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3664 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3665 this can be optimized more?
3667 2005-03-10 Raphael Neider <rneider AT web.de>
3669 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3670 genNearPointerGet): (hopefully) fixed access to bitfields via
3671 pointers (p->bitN = x; and x = p->bitN; failed)
3673 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3860 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3861 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3862 this might fix SIGSEGVs on MinGW...
3863 * src/SDCCopt.c (killDeadCode): restored original behaviour
3864 (volatile operands might get thrown away though)
3866 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

3905 when calling assembler to reflect memory model used, also define
3906 macro STACK_MODEL_{SMALL/LARGE} when compiling and assembling to
3907 reflect stack model used,

4343 * added libc directory. The current version of LibC contains string
4344 functions, ctype functions and macros and some functions of the
4345 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4346 be extensively tested in the future. Standard disclaimer here.
4347 Library is not automatically build yet. But one can build it by
4348 invoking 'make' inside the libc directory.
4349 * added ADC library under libio. Preliminary version yet.
4351 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4359 * (pic16_storeForReturn): optimized return of 0,
4360 * (genCmp): experimental code for new genCmp which uses PIC18's
4361 special compare&skip instructions. Initial tests fail some times
4362 with variables grater than 1 byte in size, so new code is disabled,
4363 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4365 * (genCast): began a fix to optimize the casting of a bit to another
4366 bit, now assigning a bitfield to another bitfield will fail, sorry,
4367 * src/pic16/main.c: disabled the use of lr-support feature,
4368 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4371 bits with offset (case PO_GPR_BIT),
4372 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4374 * (isBankInstruction): modified to return 0 for no banking instruction,
4375 and 1 for banking instruction,
4376 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4377 caused stop processing pCodes after a inline assembly block,
4378 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4379 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4380 registers when it shouldn't,
4381 * src/pic16/ralloc.c (allocReg): add preliminary support for
4382 supporting a limited set of temporary registers,
4384 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4390 (genFunction): optimize RECEIVE iCodes in reentrant functions
4392 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7389 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7391 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7392 loaded with the linker search paths (-L arguments) and the libraries
7393 to be linked with the current source (-l arguments). Changes
7394 currently will affect only the pic16 port.
7395 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7396 include path the port specific paths and port specific libraries,
7397 * gplink command now contains the $3 argument,
7398 * src/pic16/device.h,
7399 * src/pic16/device.c,: structure PIC_device is made public and
7400 renamed to PIC16_device, the same for variable Pics which is renamed

7415 Documenting changes from previous commits.
7416 * configure.in (version 1.56),
7417 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7418 when generating output files to configure the pic16 library,
7419 but now I've commented it out, since gputils aren't installed in the
7420 SF compile farm, so library won't compile
7422 * device/lib/Makefile.in (version 1.56): initially I've added in
7423 target 'all' the prerequestive 'model-pic16' so it compiled the
7424 pic16 library, but now I've commented it out for the same reasons
7426 * added targets 'model-pic16' and 'objects-pic16' to compile the
7428 * added target 'port-specific-objects-pic16' to handle the
7429 generated libraries and copy them into the build/ directory
7430 * added target 'clean-intermediate-pic16' to clean intermediate
7431 files into pic16 directory
7432 * in target 'installdirs' added line to create directory pic16 in
7433 the installation path
7435 * device/include/Makefile.in (version 1.11): in target 'install'
7436 added lines to copy all header files to installation path,

7486 data are now emitted in sorted order to reduce section naming,
7487 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7488 weren't marked as being in the access bank,
7490 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>

7525 all over. Telling LaTeX to be less strict with word spacing
7526 to better keep the right margin. Changed some notes about
7527 maintainance of the ports in section 3.2.1 - is it OK like this?
7529 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7569 * src/pic16/peeph.def: all peepholes with movff are commented out,
7570 because there is a problem in the pcode peep optimizer,
7571 * src/pic16/ralloc.c: the register allocator can now reuse local

7608 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7611 * src/z80/main.c: added missed needLinkerScript flags (more than
7612 one port structure defined in these file)
7613 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7664 include information about variables allocated to the overlay
7667 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7669 * as/mcs51/lkmain.c: Help about -Y option

7679 LEFT_OP (left shift)
7681 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7683 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7684 (default behaviour).
7686 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7688 A python script to validate compiler diagnostic messages. It can be
7689 used to verify that sdcc complains about bad c source code and
7690 gives a good location of the error.
7691 * support/valdiag/Makefile,
7692 * support/valdiag/valdiag.py,
7693 * support/valdiag/tests/*
7695 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7697 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

7708 * src/common.h: added ifndef/define/endif macros
7709 around the header file.
7710 Bug reported from Jesus Calvino-Fraga
7712 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7714 * sdcc.spec: updated
7715 * device/include/Makefile.in: don't install CVS directories
7716 * device/lib/Makefile.in: added removal of CVS directories after install
7717 * doc/Makefile: fixed install, added local_icons
7718 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7719 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7720 * src/ds390/gen.c (genRightShift): fixed bug #870788
7721 * src/SDCCast.c (decorateType): fixed bug #870781
7723 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7725 PIC16 port related changes:
7726 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7727 added variable stackPos,
7729 * gen.c: genCall, assignResultValue: added support for
7730 pushing/retrieving function parameters to/from stack,
7731 genFunction,genEndFunction: setup stack frame for the
7733 genAddrOf: will be changed according to bug 863624
7735 * added files genutils.c and genutils.h which contain gen*
7736 debugged and optimised functions extracted from gen.c
7738 * glue.c: added variable 'externs' which holds extern symbols,
7739 pic16emitRegularMap: is modified to properly handle relocatable
7740 symbols under the new scheme,
7741 pic16createInterruptVect: is modified
7742 pic16printPublics: is modified to emit 'global' assembler directives,
7743 added pic16_printExterns to print extern symbols,
7744 pic16glue: initializes stack/frame pointer in the beginning of
7745 the assembly output. Temporary hack, will be corrected later,
7746 because gplink yet does not support stack and SDCC does not
7747 yet support a type of crt0.o object to create the final binary.
7749 * Removed many lines that contain 8051 legacy code.
7750 * The code is finally placed under a 'code' directive.
7751 * Added port specific options.
7753 * _process_pragma: simplified since now we do not need *special*
7754 include file to define SFR registers. But a separate header
7755 will be needed. This will be developed later.
7756 * _pic16_parseOptions: added, parses port specific options:
7757 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7758 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7759 --preplace-udata-with=
7761 * _pic16_setDefaultOptions: modified to initialize section names,
7762 but hack is temporarly out of order since it needs improvement.
7763 * _pic16_genAssemblerPreamble: configuration words are emitted by
7764 their address instead of their name. This part is incomplete and
7765 supports only the 18Fxx2 devices. Other devices will emit an error
7766 during assembly since they do not contain the same set of config
7768 * _pic16_genIVT: is modified,
7770 * pcode.c: added definitions for some hardware registers that are needed
7772 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7773 All PCI entries are updated. Now LFSR is supported.
7774 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7775 * added pic16_newpCodeOpLit2 to support instructions with
7776 two literal arguments
7777 * pic16_pCode2str: corrected code that emits assembler instructions
7778 with two literal operands and those that have an access bit modifier
7779 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7780 this fixes a bug which caused some labels to be lost, when an
7781 assembler directive was added, i.e. banksel,
7782 * pic16_FixRegisterBanking: improved logic that causes the insertion
7784 * InlineFunction: functions that are called once, are not any more
7785 inlined. This can be a port option in the future,
7787 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7789 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7790 hold the corresponding uninitialized symbols,
7791 * pic16_allocProcessorRegister: registers have explicit marked the
7793 * pic16_allocInternalRegister: registers are explicit marked as
7795 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7796 processing list, so bit registers were lost,
7799 * ralloc.h: added field 'accessBank' and original symbol operand
7800 in register definition,
7801 * removed the field isMapped from register definition,
7803 ** Several functions have been removed from various sources:
7804 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7805 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7806 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7807 pic16_assignRelocatableRegisters
7809 ** others have been introduced:
7810 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7811 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7813 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7815 * support/scripts/inc2h.pl: changed definition of BIT_AT
7816 to emit 'sbit at' instead of 'bit at'. This was a request.
7818 PIC16 port related preliminary changes:
7819 * gen.c: prefixed function popRegFromString with
7820 pic16_ and all references to it corrected
7821 * pcode.c: all pic16_pc_* hardware registers prefixed
7822 with underscore (_),
7823 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7824 * ralloc.c: newReg(): when register is REG_SFR then
7825 set address to rIdx,
7826 pic16_allocProcessorRegister(): marks register wasUsed=0
7827 pic16_writeUsedRegs(): added a call to assign processor
7828 registers via pic16_assignFixedRegisters
7830 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7832 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7833 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7834 variables in unused register banks. Also the SSEG is placed
7835 wherever there is enough space for it, and IDATA can be anywhere
7836 in internal RAM. For now compile using -Wl-Y[stack_size].
7837 The mem file is different for this option as well, since it
7838 makes no sense of talking about DSEG lenght.
7840 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7842 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7843 in certain cases, e.g. when ROM assignment, patch provided
7844 from Albert den Haan.
7846 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8869 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8870 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

8889 A few small changes that speed up the peephole optimizer.
8893 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8895 Try to make the peephole optimizer smarter by maintaining
8896 an association between the assembly source code and the
8897 iCodes that originated them. Put this information to use
8898 with a new peephole rule condition "notVolatile" so that
8899 the rules can be aggressive yet still safe.
8904 * src/mcs51/peeph.def
8906 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8910 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

8912 if the left or right operand symbols have the accuse flag set.
8914 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8916 Changed the type of the result of the ! (NOT) operator to char;
8917 previously it returned the same type as the source. This allows
8918 us to eliminate all the genFloatNot functions (all of its target
8919 implementations were very buggy) since !float can use the same
8922 * src/SDCCicode.c (ast2iCode): ! returns char
8923 * src/mcs51/gen.c (genNot, genNotFloat),
8924 * src/ds390/gen.c (genNot, genNotFloat),
8925 * src/z80/gen.c (genNot, genNotFloat),
8926 * src/pic/gen.c (genNot, genNotFloat),

8934 2. Fixed page selection in some places
8935 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8936 the registers name strings.
8937 4. Fixed "signed / unsigned compare" compiler warnings.
8938 5. The PIC port manages its own allocation of the general purpose
8939 registers, but makes no attempt to reuse them. As a result when
8940 compiling it soon runs out of general purpose registers. Some
8941 additional code was added to the files pcode.c and device.c to walk
8942 through the function call tree and rename the registers so that they
8952 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8959 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8961 Made bitfield a distinct type from bit so that bitfields
8962 convert as per ANSI C and bits retain their traditional
8963 boolean style behaviour. Implemented bitfield support in
8971 * src/ds390/gen.c: bit v bitfield split
8972 * src/z80/gen.c: New support for bitfields
8973 * support/regression/tests/bitfields.c: reenabled z80,
8976 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8978 Rules 246.x, 247.x relate to bitfields, the others speed up
8979 access to xdata mapped I/O devices.
8981 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8983 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8985 Cleaned up genPackBits and genUnpackBits and added two helper
8986 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8987 for literal assignments in genPackBits (thanks to Frieder for
8993 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8995 Fixed bug #748310 (pointer to function type mishandled when the
8996 function name is omitted). Also fixed a SIGSEGV when a function
8997 attribute (reentrant, etc) is used on a non-function or on a
8998 function but misplaced before the parameter list.

9025 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9027 Made the constant following the "interrupt" keyword optional. If
9028 omitted, the function will not automatically be given an entry
9029 in the interrupt vector table (similar to #pragma NOIV, but
9030 less syntacticly kludgy). The interrupt number is also now
9031 range checked. Also fixed a bug in the high order bit example

9534 * src/pic16/pcode.c: Cleaned warnings
9535 * src/pic16/pcodeflow.c: Cleaned warnings
9536 * src/pic16/pcoderegs.c: Cleaned warnings

9552 it can be defined with CFLAGS when running configure
9553 * src/SDCCmain.c: fixed compiling + linking with object files
9555 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9557 * configure.in: configure for pic16 port,
9558 added --disable-pic16-port
9559 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9560 * src/SDCCmain.c: linkOptions is changed to set *,
9561 added if/endif conditional macros to remove options help
9562 messages from optionsTable when a port is not configured, added
9563 support for the PIc16 port in the ports table, when executing
9564 the compiler with no port specified on command line, a default
9565 port is selected with the new macro DEFAULT_PORT which is
9566 defined in port.h, in setDefaultOptions() linkOptions is removed
9567 from initialization assignment, since now it is a set,
9568 parseCmdLine uses setParseWithComma for linkOptions, in
9569 linkEdit() linkOptions are accessed with new function indexSet()
9570 which returns the i'th item of a set variable. See SDCCset.c, in
9571 linkEdit() when calling buildCmdLine(), added linkOptions as
9572 last argument. Now users can pass arguments to gplink via the
9573 -Wl option, main() uses pic16glue() to glue up pic16 programs

9585 * src/pic16/glue.c: commented out some error producing lines
9586 * src/pic16/main.c: __config directives are commented out to stop
9587 gpasm complaining and test the linkage with gplink, _linkCmd and
9588 _asmCmd changed to be more gplink and gpasm friendly
9589 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9590 produced an error when parsed, peep rule 12 is added to utilize
9591 movff, but it is commented out since the pCode does not support
9592 yet a command with 2 address arguments
9594 2003-05-18 <johan AT balder>
9596 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9623 2003-05-11 Borut Razem <borut.razem AT siol.net>
9625 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9626 the path of bin directory, so that PATH is the only env. variable, which has to be set

10654 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10655 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10657 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10659 * in \sdcc\as\mcs51\ changed these files in order to create an
10660 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10661 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10662 following files to include the previous two files: aslink.dsp,
10663 Makefile.aslink, Makefile.bcc, and Makefile.in.
10665 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10666 .adb instead of .cdb
10668 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10670 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10671 value from option --iram-size.
10673 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10675 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10678 2002-09-18 <wiml AT hhhh.org>
10680 * SDCClrange.h: exposed setFromRange() and setToRange()
10681 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10682 packRegsForAccUse() (bug 542397)
10683 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10684 multiple times and emitting the fetch operations more than once
10685 added aopGetUsesAcc() function to allow binary operators to
10686 fetch their operands in the correct order; made genMinus() emit
10687 compact code for X = LITERAL - Y
10689 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10690 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10691 sprintf() in line 1267.
10693 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10694 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10697 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10698 Changes to aslink (All the changes are marked with 'JCF'):
10700 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10703 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10704 area BSEG. Also moves, if possible, the DATA area down into the internal
10705 ram so more space is available.
10707 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10710 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10711 not bytes. Function summary() which creates a memory usage summary
10712 file with extension .mem. Reports of overlaping stack and small stack
10713 size. If the space for the stack is less than 16 bytes aslink trows a
10716 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10717 the 8051. Option 'y' for memory summary output file.
10719 Changes to sdcc (All the changes are marked with 'JCF'):
10721 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10723 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10724 overlaying area for it (uses RegBankUsed[4]).
10726 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10727 bank zero as used by default. By default aslink locates the stack
10728 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10729 the creation of the .mem file. Delegates the allocation of data area
10730 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10731 the begining of the stack area to aslink.
10733 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10734 glue() in SDCCglue.c creates an area for it.
10736 2002-09-03 Borut Razem <borut.razem AT siol.net>
10737 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10738 sdcc/src/pic/glue.c:
10739 introduced atexit() handler for teporay files removal in case of
10740 errors, assertions, ...
10742 2002-08-29 Borut Razem <borut.razem AT siol.net>
10743 * sdcc/support/cpp2/auto-host_vc_in.h:
10744 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10745 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10746 Maybe there is a similar problem with BORLANDC? It should be checked!
10748 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10749 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10750 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10751 was not executed, and the compiler (cl) launched a warning:
10752 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10754 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10755 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10757 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10758 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10760 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10761 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10762 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10763 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10764 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10765 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10766 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10767 - added Release configuration in VS projects
10768 - review of compiler an linker options
10769 - VC .exe files are generated in bin_vc directory, not to interfere
10770 with binaries generated from other projects (cygwin, mingw, bcc ...)
10772 * sdcc/src/yacc.dsp: added
10774 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10775 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10776 and insert the version number definitions from .version
10778 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10780 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10781 added - genarate auto-host.h using auto-host_vc_in.h as template
10784 removed from CVS, generated automatically
10786 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10787 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10789 2002-08-11 Borut Razem <borut.razem AT siol.net>
10790 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10792 2002-08-10 Borut Razem <borut.razem AT siol.net>
10793 * src/SDCCmain.c (main):
10794 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10795 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10796 The consequence was that some temporary files were not removed.

11008 Previous fix was not good. basic blocks that have "break" or "return" are
11009 not really partof a loop , but live ranges used in these blocks should
