780 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
782 Enabled VPATH feature: changed nearly all Makefiles (149 files).
783 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
785 One basic decision: e.g. src/clean.mk includes further files. In order
786 to make this work there are two solutions:
787 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
788 run configure on them. This way they can use
789 'include $(srcdir)/port-clean.mk'
790 - always include clean.mk by the Makefile at the same level. To avoid
791 that `make clean` tries to include and build Makefile.dep the
792 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
793 implemented, because now even `make uninstall` doesn't create
794 Makefile.in. clean.mk could be eliminated by pasting it in
797 * debugger/mcs51/Makefile.in: build own objects from library sources
798 (SLIB, SDCC) in current directory
800 * configure, configure.in: renamed --disable-device-lib-build in
801 --disable-device-lib; added --enable-doc, the required tools are
802 searched by configure; added result message; the toolchain for the
803 belonging ports are now only built, if the port is enabled.
805 * support/regression/*: all output is written in directory gen, because
806 the fwk and ports directories don't livet in the build tree using vpath
808 * doc/sdccman.lyx: renamed --disable-device-lib-build to
809 --disable-device-lib, added --enable-doc, added section VPATH
811 * sim/ucsim/configure.in,
812 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
813 z80 are enabled by default
815 2006-04-24 Raphael Neider <rneider AT web.de>
817 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
818 to config word, "pic14_"-prefixed some extern functions
819 (pic14_emitConfigWord): emit __config directive(s) if assignment to
820 config word has been found
821 * src/pic/device.h: added prototypes
822 * src/pic/pcode.c: added "pic14_"-prefix where needed
823 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
825 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
827 (pic14emitRegularMap): ignore config words,
828 (pic14createInterruptVect): moved generating __config directives away
829 (picglue): have __config directives emitted
831 2006-04-24 Borut Razem <borut.razem AT siol.net>
833 * doc/Makefile: sync with nightly build makefile

838 registers that have not been assigned proper liveranges,
839 fixes #1469504 and #1474602,
840 (pCodeRegOptimizeRegUsage): fixed typo in comment
842 2006-04-24 Borut Razem <borut.razem AT siol.net>
844 * device/examples/main8051.c: deleted - it was removed from CVS

1086 implemented patch 1120823 Thanks to Willy De la Court (normal
1087 interrupts need an interrupt number now if they are made critical),
1088 and enabled nesting of critical functions though not for gbz80
1089 (genCritical, genEndCritical): added functions
1090 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1091 * src/z80/mappings.i: added "ei" to all mappings

1103 the left operand is shorter than the result (c* = lit-c* + int),
1105 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1108 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1110 * src/.version: increased version number to 2.5.5
1111 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1112 linking is done manually in pic16 port's _linkEdit,
1113 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1114 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1115 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1116 allocate asmop as AOP_ACC,
1117 (aopForRemat): added parameter 'bool result' in function declaration,
1118 (pic16_aopGet): return AOP_ACC when accessing WREG,
1119 (pic16_popGetTempReg): minor modification,

1130 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1131 call to allocReg, not by manually allocating a new one,
1132 (pic16_assignRegisters): now before going through the register
1133 allocating functions mark all registers as free. This eliminates some
1134 side effects resulting from peephole parser done earlier in the backbone
1136 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1194 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1195 which dumps before the function entry point a data byte which represents
1196 the number of the local variables used by the specified function, added
1197 'xinst' for initial support for Extended Instruction Support,
1198 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1199 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1200 port->fun_prefix anymore (may change later),
1201 (genFunction, genEndFunction): do not store/restore local registers for
1202 _main (this should take care the --main-return command line option in
1204 (genOr): removed some legacy pic-port instructions,
1205 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1206 performing operations with SFR's causes data to be written more than
1207 once to each SFR. Perhaps SFRs should be handled in special cases...
1208 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1210 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1211 into account for stack starting position,

1213 --extended or -y for Extended Instruction Support,
1214 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1215 (deassignLRs): *** perhaps the most important change, old 'for' code
1216 (commented out for reference), didn't account for some registers which
1217 were left marked 'not free' after a pointer operation. The change
1218 reduces register usage a lot in some cases

3482 if condition == CARRY)
3483 * (genCmp): adapted to new genSkipc semantics
3484 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
3485 on rIfx (genCmp was broken)
3487 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3489 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3490 * src/z80/main.c (_keywords[]),
3491 * src/SDCCglobal.h (struct options),
3493 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3494 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3495 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3496 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3497 always available in leading double underscore form. The C99 support is
3498 mostly missing, but it's a start.
3499 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3500 reserved identifier "__data".
3502 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3504 * src/mcs51/peeph.def: fixed bug 1170013

3512 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
3515 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3517 * src/port.h (struct PORT),

3546 immedDom() returning wrong block; probably fixes bug #1160833)
3548 2005-03-20 Borut Razem <borut.razem AT siol.net>
3550 * support/scripts/inc2h.pl: WIN32 port
3552 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3554 * device/lib/makefile.in: added abs.c and labs.c
3556 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3558 * device/include/stdint.h: added
3559 * device/lib/abs.c: added
3560 * device/lib/labs.c: added
3561 * device/include/stdlib.h: added abs() and labs() prototypes

3578 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3580 * device/lib/printf_large.c: removed inline assembly for portability and
3581 readability. Use printf_fast if speed or size are more important.
3582 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3583 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3585 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3587 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3588 prevent compiler warning
3590 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3592 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3593 moved to level 0 and declared as static. Also they are explicit
3594 placed in access bank. This was necessery because some times they
3595 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3596 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3597 optimizations. Currently only compare to unsigned char is implemented,
3598 * src/pic16/gen.c: added fReturnIdx array,
3599 * (struct resolvedIfx) is moved to gen.h and made public,
3600 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3601 * (aopForSym): added an optimization to directly store in stack of
3602 the operand of a SEND iCode,
3603 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3604 but as registers instead (AOP_REG) using the fReturnIdx array,
3605 * (pic16_freeAsmop): remove the freed register from the
3606 _G.sregsAlloc field,
3607 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3608 a compare of 'WREG',
3609 * (pic16_popGetTempRegCond): changed function prototype, now
3610 function takes also a bitVector argument v which holds the current
3611 set of registers that are allocated for stack access by aopForSym,
3612 registers allocated in aopForSym for accessing stack symbols are not
3613 any more part of the functions usedRegs field,
3614 * (genCall): some times aopOp is called for a stack variable to be
3615 send, aopForSym might perform the push, if this is true make sure
3616 that genCall doesn't push the variable twice by testing _G.resDirect,
3617 * (genFunction): changed testing for unspecified interrupt number
3618 from 256 to INTNO_UNSPEC,
3619 * modified selection scheme of frame pointer generation. Previously
3620 if function did use local registers a frame pointer was generated,
3621 now a frame pointer is generated only if function has arguments
3622 (that need PLUSW2 register access), or has stack arguments, or the
3623 compiler is not instructed to omit the frame pointer,
3624 * (genEndFunction): before restoring local registers that were saved
3625 in the function preamble, also restore the registers that *might*
3626 have been allocated for stack access,
3627 * (genRet): removed some old comments,
3628 * (genCmp, the active (RN's) version): added a call to the
3629 pic16_genCmp_special function to perform the compare with a more
3630 robust and optimized way,
3631 * (genInline): a feature has been added in inline code generation,
3632 which allows a wildcard variable substitution when writing inline
3633 assembly. Code is incomplete and experimental therefore undocumented,
3634 * (genCast): changed order of aopOp for result and right to allow
3635 aopForSym to directly load the result if possible,
3636 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3637 perform an optimized compare on some selected special occasions,
3638 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3639 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3640 generate an IVT any more,
3641 * src/pic16/main.c (pic16_optionsTable): added command line option
3643 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3644 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3646 * src/pic16/NOTES: Raphael Neider added in list of active developers
3647 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3648 jumptable_end to prevent bug #,
3649 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3650 inCond and outCond fields,
3651 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3652 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3653 turn off register spilling,
3654 * (packRegsForOneUse): synced with other ports' versions although it
3655 is not used currently,
3656 * (pic16_packRegisters): added an optimization while reading
3657 structure bitfields, some registers may be saved (malloc code is
3658 decreased by 80 bytes)
3660 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3662 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3663 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3664 this can be optimized more?
3666 2005-03-10 Raphael Neider <rneider AT web.de>
3668 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3669 genNearPointerGet): (hopefully) fixed access to bitfields via
3670 pointers (p->bitN = x; and x = p->bitN; failed)
3672 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3859 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3860 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3861 this might fix SIGSEGVs on MinGW...
3862 * src/SDCCopt.c (killDeadCode): restored original behaviour
3863 (volatile operands might get thrown away though)
3865 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

4342 * added libc directory. The current version of LibC contains string
4343 functions, ctype functions and macros and some functions of the
4344 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4345 be extensively tested in the future. Standard disclaimer here.
4346 Library is not automatically build yet. But one can build it by
4347 invoking 'make' inside the libc directory.
4348 * added ADC library under libio. Preliminary version yet.
4350 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4358 * (pic16_storeForReturn): optimized return of 0,
4359 * (genCmp): experimental code for new genCmp which uses PIC18's
4360 special compare&skip instructions. Initial tests fail some times
4361 with variables grater than 1 byte in size, so new code is disabled,
4362 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4364 * (genCast): began a fix to optimize the casting of a bit to another
4365 bit, now assigning a bitfield to another bitfield will fail, sorry,
4366 * src/pic16/main.c: disabled the use of lr-support feature,
4367 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4368 * added some function prototypes, added function _debugf prototype,

4370 bits with offset (case PO_GPR_BIT),
4371 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4373 * (isBankInstruction): modified to return 0 for no banking instruction,
4374 and 1 for banking instruction,
4375 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4376 caused stop processing pCodes after a inline assembly block,
4377 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4378 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4379 registers when it shouldn't,
4380 * src/pic16/ralloc.c (allocReg): add preliminary support for
4381 supporting a limited set of temporary registers,
4383 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4389 (genFunction): optimize RECEIVE iCodes in reentrant functions
4391 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7388 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7390 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7391 loaded with the linker search paths (-L arguments) and the libraries
7392 to be linked with the current source (-l arguments). Changes
7393 currently will affect only the pic16 port.
7394 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7395 include path the port specific paths and port specific libraries,
7396 * gplink command now contains the $3 argument,
7397 * src/pic16/device.h,
7398 * src/pic16/device.c,: structure PIC_device is made public and
7399 renamed to PIC16_device, the same for variable Pics which is renamed

7414 Documenting changes from previous commits.
7415 * configure.in (version 1.56),
7416 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7417 when generating output files to configure the pic16 library,
7418 but now I've commented it out, since gputils aren't installed in the
7419 SF compile farm, so library won't compile
7421 * device/lib/Makefile.in (version 1.56): initially I've added in
7422 target 'all' the prerequestive 'model-pic16' so it compiled the
7423 pic16 library, but now I've commented it out for the same reasons
7425 * added targets 'model-pic16' and 'objects-pic16' to compile the
7427 * added target 'port-specific-objects-pic16' to handle the
7428 generated libraries and copy them into the build/ directory
7429 * added target 'clean-intermediate-pic16' to clean intermediate
7430 files into pic16 directory
7431 * in target 'installdirs' added line to create directory pic16 in
7432 the installation path
7434 * device/include/Makefile.in (version 1.11): in target 'install'
7435 added lines to copy all header files to installation path,

7482 via literal number. The symbol is placed in the corresponding
7483 position of the data ram
7484 * (pic16_dump_section): relocatable and absolute uninitialized
7485 data are now emitted in sorted order to reduce section naming,
7486 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7487 weren't marked as being in the access bank,
7489 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7491 Added portion of GNU PIC Library under the directory
7492 device/include/pic16 and device/lib/pic16. These files
7493 contain the declarations of SFRs for the PIC18Fxx2 devices.

7524 all over. Telling LaTeX to be less strict with word spacing
7525 to better keep the right margin. Changed some notes about
7526 maintainance of the ports in section 3.2.1 - is it OK like this?
7528 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7568 * src/pic16/peeph.def: all peepholes with movff are commented out,
7569 because there is a problem in the pcode peep optimizer,
7570 * src/pic16/ralloc.c: the register allocator can now reuse local

7663 include information about variables allocated to the overlay
7666 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7668 * as/mcs51/lkmain.c: Help about -Y option

7678 LEFT_OP (left shift)
7680 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7682 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7683 (default behaviour).
7685 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7687 A python script to validate compiler diagnostic messages. It can be
7688 used to verify that sdcc complains about bad c source code and
7689 gives a good location of the error.
7690 * support/valdiag/Makefile,
7691 * support/valdiag/valdiag.py,
7692 * support/valdiag/tests/*
7694 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7696 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

7707 * src/common.h: added ifndef/define/endif macros
7708 around the header file.
7709 Bug reported from Jesus Calvino-Fraga
7711 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7713 * sdcc.spec: updated
7714 * device/include/Makefile.in: don't install CVS directories
7715 * device/lib/Makefile.in: added removal of CVS directories after install
7716 * doc/Makefile: fixed install, added local_icons
7717 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7718 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7719 * src/ds390/gen.c (genRightShift): fixed bug #870788
7720 * src/SDCCast.c (decorateType): fixed bug #870781
7722 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7724 PIC16 port related changes:
7725 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7726 added variable stackPos,
7728 * gen.c: genCall, assignResultValue: added support for
7729 pushing/retrieving function parameters to/from stack,
7730 genFunction,genEndFunction: setup stack frame for the
7732 genAddrOf: will be changed according to bug 863624
7734 * added files genutils.c and genutils.h which contain gen*
7735 debugged and optimised functions extracted from gen.c
7737 * glue.c: added variable 'externs' which holds extern symbols,
7738 pic16emitRegularMap: is modified to properly handle relocatable
7739 symbols under the new scheme,
7740 pic16createInterruptVect: is modified
7741 pic16printPublics: is modified to emit 'global' assembler directives,
7742 added pic16_printExterns to print extern symbols,
7743 pic16glue: initializes stack/frame pointer in the beginning of
7744 the assembly output. Temporary hack, will be corrected later,
7745 because gplink yet does not support stack and SDCC does not
7746 yet support a type of crt0.o object to create the final binary.
7748 * Removed many lines that contain 8051 legacy code.
7749 * The code is finally placed under a 'code' directive.
7750 * Added port specific options.
7752 * _process_pragma: simplified since now we do not need *special*
7753 include file to define SFR registers. But a separate header
7754 will be needed. This will be developed later.
7755 * _pic16_parseOptions: added, parses port specific options:
7756 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7757 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7758 --preplace-udata-with=
7760 * _pic16_setDefaultOptions: modified to initialize section names,
7761 but hack is temporarly out of order since it needs improvement.
7762 * _pic16_genAssemblerPreamble: configuration words are emitted by
7763 their address instead of their name. This part is incomplete and
7764 supports only the 18Fxx2 devices. Other devices will emit an error
7765 during assembly since they do not contain the same set of config
7767 * _pic16_genIVT: is modified,
7769 * pcode.c: added definitions for some hardware registers that are needed
7771 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7772 All PCI entries are updated. Now LFSR is supported.
7773 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7774 * added pic16_newpCodeOpLit2 to support instructions with
7775 two literal arguments
7776 * pic16_pCode2str: corrected code that emits assembler instructions
7777 with two literal operands and those that have an access bit modifier
7778 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7779 this fixes a bug which caused some labels to be lost, when an
7780 assembler directive was added, i.e. banksel,
7781 * pic16_FixRegisterBanking: improved logic that causes the insertion
7783 * InlineFunction: functions that are called once, are not any more
7784 inlined. This can be a port option in the future,
7786 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7788 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7789 hold the corresponding uninitialized symbols,
7790 * pic16_allocProcessorRegister: registers have explicit marked the
7792 * pic16_allocInternalRegister: registers are explicit marked as
7794 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7795 processing list, so bit registers were lost,
7798 * ralloc.h: added field 'accessBank' and original symbol operand
7799 in register definition,
7800 * removed the field isMapped from register definition,
7802 ** Several functions have been removed from various sources:
7803 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7804 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7805 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7806 pic16_assignRelocatableRegisters
7808 ** others have been introduced:
7809 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7810 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7812 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7814 * support/scripts/inc2h.pl: changed definition of BIT_AT
7815 to emit 'sbit at' instead of 'bit at'. This was a request.
7817 PIC16 port related preliminary changes:
7818 * gen.c: prefixed function popRegFromString with
7819 pic16_ and all references to it corrected
7820 * pcode.c: all pic16_pc_* hardware registers prefixed
7821 with underscore (_),
7822 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7823 * ralloc.c: newReg(): when register is REG_SFR then
7824 set address to rIdx,
7825 pic16_allocProcessorRegister(): marks register wasUsed=0
7826 pic16_writeUsedRegs(): added a call to assign processor
7827 registers via pic16_assignFixedRegisters
7829 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7831 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7832 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7833 variables in unused register banks. Also the SSEG is placed
7834 wherever there is enough space for it, and IDATA can be anywhere
7835 in internal RAM. For now compile using -Wl-Y[stack_size].
7836 The mem file is different for this option as well, since it
7837 makes no sense of talking about DSEG lenght.
7839 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7841 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7842 in certain cases, e.g. when ROM assignment, patch provided
7843 from Albert den Haan.
7845 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8868 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8869 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

8888 A few small changes that speed up the peephole optimizer.
8892 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8894 Try to make the peephole optimizer smarter by maintaining
8895 an association between the assembly source code and the
8896 iCodes that originated them. Put this information to use
8897 with a new peephole rule condition "notVolatile" so that
8898 the rules can be aggressive yet still safe.
8903 * src/mcs51/peeph.def
8905 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8909 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

8911 if the left or right operand symbols have the accuse flag set.
8913 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8915 Changed the type of the result of the ! (NOT) operator to char;
8916 previously it returned the same type as the source. This allows
8917 us to eliminate all the genFloatNot functions (all of its target
8918 implementations were very buggy) since !float can use the same
8921 * src/SDCCicode.c (ast2iCode): ! returns char
8922 * src/mcs51/gen.c (genNot, genNotFloat),
8923 * src/ds390/gen.c (genNot, genNotFloat),
8924 * src/z80/gen.c (genNot, genNotFloat),
8925 * src/pic/gen.c (genNot, genNotFloat),

8933 2. Fixed page selection in some places
8934 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8935 the registers name strings.
8936 4. Fixed "signed / unsigned compare" compiler warnings.
8937 5. The PIC port manages its own allocation of the general purpose
8938 registers, but makes no attempt to reuse them. As a result when
8939 compiling it soon runs out of general purpose registers. Some
8940 additional code was added to the files pcode.c and device.c to walk
8941 through the function call tree and rename the registers so that they
8951 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8958 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8960 Made bitfield a distinct type from bit so that bitfields
8961 convert as per ANSI C and bits retain their traditional
8962 boolean style behaviour. Implemented bitfield support in
8970 * src/ds390/gen.c: bit v bitfield split
8971 * src/z80/gen.c: New support for bitfields
8972 * support/regression/tests/bitfields.c: reenabled z80,
8975 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8977 Rules 246.x, 247.x relate to bitfields, the others speed up
8978 access to xdata mapped I/O devices.
8980 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8982 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8984 Cleaned up genPackBits and genUnpackBits and added two helper
8985 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8986 for literal assignments in genPackBits (thanks to Frieder for
8992 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8994 Fixed bug #748310 (pointer to function type mishandled when the
8995 function name is omitted). Also fixed a SIGSEGV when a function
8996 attribute (reentrant, etc) is used on a non-function or on a
8997 function but misplaced before the parameter list.

9024 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9026 Made the constant following the "interrupt" keyword optional. If
9027 omitted, the function will not automatically be given an entry
9028 in the interrupt vector table (similar to #pragma NOIV, but
9029 less syntacticly kludgy). The interrupt number is also now
9030 range checked. Also fixed a bug in the high order bit example

9533 * src/pic16/pcode.c: Cleaned warnings
9534 * src/pic16/pcodeflow.c: Cleaned warnings
9535 * src/pic16/pcoderegs.c: Cleaned warnings

9548 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9550 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9551 it can be defined with CFLAGS when running configure
9552 * src/SDCCmain.c: fixed compiling + linking with object files
9554 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9556 * configure.in: configure for pic16 port,
9557 added --disable-pic16-port
9558 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9559 * src/SDCCmain.c: linkOptions is changed to set *,
9560 added if/endif conditional macros to remove options help
9561 messages from optionsTable when a port is not configured, added
9562 support for the PIc16 port in the ports table, when executing
9563 the compiler with no port specified on command line, a default
9564 port is selected with the new macro DEFAULT_PORT which is
9565 defined in port.h, in setDefaultOptions() linkOptions is removed
9566 from initialization assignment, since now it is a set,
9567 parseCmdLine uses setParseWithComma for linkOptions, in
9568 linkEdit() linkOptions are accessed with new function indexSet()
9569 which returns the i'th item of a set variable. See SDCCset.c, in
9570 linkEdit() when calling buildCmdLine(), added linkOptions as
9571 last argument. Now users can pass arguments to gplink via the
9572 -Wl option, main() uses pic16glue() to glue up pic16 programs

9584 * src/pic16/glue.c: commented out some error producing lines
9585 * src/pic16/main.c: __config directives are commented out to stop
9586 gpasm complaining and test the linkage with gplink, _linkCmd and
9587 _asmCmd changed to be more gplink and gpasm friendly
9588 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9589 produced an error when parsed, peep rule 12 is added to utilize
9590 movff, but it is commented out since the pCode does not support
9591 yet a command with 2 address arguments
9593 2003-05-18 <johan AT balder>
9595 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9622 2003-05-11 Borut Razem <borut.razem AT siol.net>
9624 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9625 the path of bin directory, so that PATH is the only env. variable, which has to be set

10653 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10654 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10656 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10658 * in \sdcc\as\mcs51\ changed these files in order to create an
10659 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10660 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10661 following files to include the previous two files: aslink.dsp,
10662 Makefile.aslink, Makefile.bcc, and Makefile.in.
10664 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10665 .adb instead of .cdb
10667 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10669 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10670 value from option --iram-size.
10672 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10674 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10677 2002-09-18 <wiml AT hhhh.org>
10679 * SDCClrange.h: exposed setFromRange() and setToRange()
10680 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10681 packRegsForAccUse() (bug 542397)
10682 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10683 multiple times and emitting the fetch operations more than once
10684 added aopGetUsesAcc() function to allow binary operators to
10685 fetch their operands in the correct order; made genMinus() emit
10686 compact code for X = LITERAL - Y
10688 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10689 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10690 sprintf() in line 1267.
10692 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10693 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10696 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10697 Changes to aslink (All the changes are marked with 'JCF'):
10699 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10702 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10703 area BSEG. Also moves, if possible, the DATA area down into the internal
10704 ram so more space is available.
10706 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10709 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10710 not bytes. Function summary() which creates a memory usage summary
10711 file with extension .mem. Reports of overlaping stack and small stack
10712 size. If the space for the stack is less than 16 bytes aslink trows a
10715 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10716 the 8051. Option 'y' for memory summary output file.
10718 Changes to sdcc (All the changes are marked with 'JCF'):
10720 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10722 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10723 overlaying area for it (uses RegBankUsed[4]).
10725 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10726 bank zero as used by default. By default aslink locates the stack
10727 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10728 the creation of the .mem file. Delegates the allocation of data area
10729 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10730 the begining of the stack area to aslink.
10732 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10733 glue() in SDCCglue.c creates an area for it.
10735 2002-09-03 Borut Razem <borut.razem AT siol.net>
10736 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10737 sdcc/src/pic/glue.c:
10738 introduced atexit() handler for teporay files removal in case of
10739 errors, assertions, ...
10741 2002-08-29 Borut Razem <borut.razem AT siol.net>
10742 * sdcc/support/cpp2/auto-host_vc_in.h:
10743 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10744 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10745 Maybe there is a similar problem with BORLANDC? It should be checked!
10747 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10748 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10749 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10750 was not executed, and the compiler (cl) launched a warning:
10751 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10753 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10754 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10756 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10757 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10759 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10760 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10761 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10762 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10763 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10764 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10765 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10766 - added Release configuration in VS projects
10767 - review of compiler an linker options
10768 - VC .exe files are generated in bin_vc directory, not to interfere
10769 with binaries generated from other projects (cygwin, mingw, bcc ...)
10771 * sdcc/src/yacc.dsp: added
10773 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10774 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10775 and insert the version number definitions from .version
10777 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10779 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10780 added - genarate auto-host.h using auto-host_vc_in.h as template
10783 removed from CVS, generated automatically
10785 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10786 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10788 2002-08-11 Borut Razem <borut.razem AT siol.net>
10789 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10791 2002-08-10 Borut Razem <borut.razem AT siol.net>
10792 * src/SDCCmain.c (main):
10793 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10794 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10795 The consequence was that some temporary files were not removed.
