775 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
777 Enabled VPATH feature: changed nearly all Makefiles (149 files).
778 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
780 One basic decision: e.g. src/clean.mk includes further files. In order
781 to make this work there are two solutions:
782 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
783 run configure on them. This way they can use
784 'include $(srcdir)/port-clean.mk'
785 - always include clean.mk by the Makefile at the same level. To avoid
786 that `make clean` tries to include and build Makefile.dep the
787 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
788 implemented, because now even `make uninstall` doesn't create
789 Makefile.in. clean.mk could be eliminated by pasting it in
792 * debugger/mcs51/Makefile.in: build own objects from library sources
793 (SLIB, SDCC) in current directory
795 * configure, configure.in: renamed --disable-device-lib-build in
796 --disable-device-lib; added --enable-doc, the required tools are
797 searched by configure; added result message; the toolchain for the
798 belonging ports are now only built, if the port is enabled.
800 * support/regression/*: all output is written in directory gen, because
801 the fwk and ports directories don't livet in the build tree using vpath
803 * doc/sdccman.lyx: renamed --disable-device-lib-build to
804 --disable-device-lib, added --enable-doc, added section VPATH
806 * sim/ucsim/configure.in,
807 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
808 z80 are enabled by default
810 2006-04-24 Raphael Neider <rneider AT web.de>
812 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
813 to config word, "pic14_"-prefixed some extern functions
814 (pic14_emitConfigWord): emit __config directive(s) if assignment to
815 config word has been found
816 * src/pic/device.h: added prototypes
817 * src/pic/pcode.c: added "pic14_"-prefix where needed
818 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
820 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
822 (pic14emitRegularMap): ignore config words,
823 (pic14createInterruptVect): moved generating __config directives away
824 (picglue): have __config directives emitted

834 fixes #1469504 and #1474602,
835 (pCodeRegOptimizeRegUsage): fixed typo in comment

1081 implemented patch 1120823 Thanks to Willy De la Court (normal
1082 interrupts need an interrupt number now if they are made critical),
1083 and enabled nesting of critical functions though not for gbz80
1084 (genCritical, genEndCritical): added functions
1085 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1086 * src/z80/mappings.i: added "ei" to all mappings

1098 the left operand is shorter than the result (c* = lit-c* + int),
1100 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1103 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1105 * src/.version: increased version number to 2.5.5
1106 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1107 linking is done manually in pic16 port's _linkEdit,
1108 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1109 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1110 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1111 allocate asmop as AOP_ACC,
1112 (aopForRemat): added parameter 'bool result' in function declaration,
1113 (pic16_aopGet): return AOP_ACC when accessing WREG,
1114 (pic16_popGetTempReg): minor modification,
1115 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1116 'pic16_allocWithIdx',

1123 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1125 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1126 call to allocReg, not by manually allocating a new one,
1127 (pic16_assignRegisters): now before going through the register
1128 allocating functions mark all registers as free. This eliminates some
1129 side effects resulting from peephole parser done earlier in the backbone
1131 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1153 (aopForSym, aopOp): increment asmop.allocated if reused,
1154 (freeAsmop): decrement asmop.allocated and check for zero instead of
1156 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1157 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1158 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1181 2006-03-06 Borut Razem <borut.razem AT siol.net>
1183 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1184 made the linker quiet

1189 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1190 which dumps before the function entry point a data byte which represents
1191 the number of the local variables used by the specified function, added
1192 'xinst' for initial support for Extended Instruction Support,
1193 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1194 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1195 port->fun_prefix anymore (may change later),
1196 (genFunction, genEndFunction): do not store/restore local registers for
1197 _main (this should take care the --main-return command line option in
1199 (genOr): removed some legacy pic-port instructions,
1200 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1201 performing operations with SFR's causes data to be written more than
1202 once to each SFR. Perhaps SFRs should be handled in special cases...
1203 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1205 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1206 into account for stack starting position,

1208 --extended or -y for Extended Instruction Support,
1209 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1210 (deassignLRs): *** perhaps the most important change, old 'for' code
1211 (commented out for reference), didn't account for some registers which
1212 were left marked 'not free' after a pointer operation. The change
1213 reduces register usage a lot in some cases
1215 2006-03-04 Borut Razem <borut.razem AT siol.net>

3462 * device/lib/pic16/startup/{crt0i.c, crt0iz.c}: redesign of the
3463 _do_cinit function, because the previous failed when local variables
3464 where not placed in the same memory bank,
3465 * device/lib/pic16/libsdcc/char/: various modifications to improve
3466 library performance,
3467 * doc/sdccman.lyx: some reorganization of the PIC16 part, added many
3468 information on the new functions of the c library and more...
3470 2005-03-28 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3472 * src/SDCCBBlock.c (iCodeBreakDown): fixed bug #1170212

3477 if condition == CARRY)
3478 * (genCmp): adapted to new genSkipc semantics
3479 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
3480 on rIfx (genCmp was broken)
3482 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3484 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3485 * src/z80/main.c (_keywords[]),
3486 * src/SDCCglobal.h (struct options),
3488 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3489 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3490 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3491 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3492 always available in leading double underscore form. The C99 support is
3493 mostly missing, but it's a start.
3494 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3495 reserved identifier "__data".
3497 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3499 * src/mcs51/peeph.def: fixed bug 1170013

3507 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
3510 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3512 * src/port.h (struct PORT),

3541 immedDom() returning wrong block; probably fixes bug #1160833)
3543 2005-03-20 Borut Razem <borut.razem AT siol.net>
3545 * support/scripts/inc2h.pl: WIN32 port
3547 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3549 * device/lib/makefile.in: added abs.c and labs.c
3551 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3553 * device/include/stdint.h: added
3554 * device/lib/abs.c: added
3555 * device/lib/labs.c: added
3556 * device/include/stdlib.h: added abs() and labs() prototypes

3573 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3575 * device/lib/printf_large.c: removed inline assembly for portability and
3576 readability. Use printf_fast if speed or size are more important.
3577 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3578 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3580 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3582 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3583 prevent compiler warning
3585 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3587 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3588 moved to level 0 and declared as static. Also they are explicit
3589 placed in access bank. This was necessery because some times they
3590 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3591 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3592 optimizations. Currently only compare to unsigned char is implemented,
3593 * src/pic16/gen.c: added fReturnIdx array,
3594 * (struct resolvedIfx) is moved to gen.h and made public,
3595 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3596 * (aopForSym): added an optimization to directly store in stack of
3597 the operand of a SEND iCode,
3598 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3599 but as registers instead (AOP_REG) using the fReturnIdx array,
3600 * (pic16_freeAsmop): remove the freed register from the
3601 _G.sregsAlloc field,
3602 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3603 a compare of 'WREG',
3604 * (pic16_popGetTempRegCond): changed function prototype, now
3605 function takes also a bitVector argument v which holds the current
3606 set of registers that are allocated for stack access by aopForSym,
3607 registers allocated in aopForSym for accessing stack symbols are not
3608 any more part of the functions usedRegs field,
3609 * (genCall): some times aopOp is called for a stack variable to be
3610 send, aopForSym might perform the push, if this is true make sure
3611 that genCall doesn't push the variable twice by testing _G.resDirect,
3612 * (genFunction): changed testing for unspecified interrupt number
3613 from 256 to INTNO_UNSPEC,
3614 * modified selection scheme of frame pointer generation. Previously
3615 if function did use local registers a frame pointer was generated,
3616 now a frame pointer is generated only if function has arguments
3617 (that need PLUSW2 register access), or has stack arguments, or the
3618 compiler is not instructed to omit the frame pointer,
3619 * (genEndFunction): before restoring local registers that were saved
3620 in the function preamble, also restore the registers that *might*
3621 have been allocated for stack access,
3622 * (genRet): removed some old comments,
3623 * (genCmp, the active (RN's) version): added a call to the
3624 pic16_genCmp_special function to perform the compare with a more
3625 robust and optimized way,
3626 * (genInline): a feature has been added in inline code generation,
3627 which allows a wildcard variable substitution when writing inline
3628 assembly. Code is incomplete and experimental therefore undocumented,
3629 * (genCast): changed order of aopOp for result and right to allow
3630 aopForSym to directly load the result if possible,
3631 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3632 perform an optimized compare on some selected special occasions,
3633 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3634 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3635 generate an IVT any more,
3636 * src/pic16/main.c (pic16_optionsTable): added command line option
3638 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3639 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3641 * src/pic16/NOTES: Raphael Neider added in list of active developers
3642 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3643 jumptable_end to prevent bug #,
3644 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3645 inCond and outCond fields,
3646 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3647 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3648 turn off register spilling,
3649 * (packRegsForOneUse): synced with other ports' versions although it
3650 is not used currently,
3651 * (pic16_packRegisters): added an optimization while reading
3652 structure bitfields, some registers may be saved (malloc code is
3653 decreased by 80 bytes)
3655 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3657 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3658 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3659 this can be optimized more?
3661 2005-03-10 Raphael Neider <rneider AT web.de>
3663 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3664 genNearPointerGet): (hopefully) fixed access to bitfields via
3665 pointers (p->bitN = x; and x = p->bitN; failed)
3667 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3854 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3855 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3856 this might fix SIGSEGVs on MinGW...
3857 * src/SDCCopt.c (killDeadCode): restored original behaviour
3858 (volatile operands might get thrown away though)
3860 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

4299 Adding support for replacing ljmps with sjmps in jumptables
4300 generated for switch statements. For now you need to set the
4301 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4302 Now 4 algorithms for mcs51 jumptable generation are used:
4303 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4304 addresses loaded pc-relative for up to 112 cases and stack-pushing
4305 target addresses loaded with offset from dptr for up to 256 cases.

4331 Large cummulative patch for pic16 port.
4332 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4333 to call when a stack overflow occurs,
4334 * (malloc.h): added CVS Id tag,
4335 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4337 * added libc directory. The current version of LibC contains string
4338 functions, ctype functions and macros and some functions of the
4339 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4340 be extensively tested in the future. Standard disclaimer here.

7383 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7385 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7386 loaded with the linker search paths (-L arguments) and the libraries
7387 to be linked with the current source (-l arguments). Changes
7388 currently will affect only the pic16 port.
7389 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7390 include path the port specific paths and port specific libraries,
7391 * gplink command now contains the $3 argument,
7392 * src/pic16/device.h,
7393 * src/pic16/device.c,: structure PIC_device is made public and
7394 renamed to PIC16_device, the same for variable Pics which is renamed

7409 Documenting changes from previous commits.
7410 * configure.in (version 1.56),
7411 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7412 when generating output files to configure the pic16 library,
7413 but now I've commented it out, since gputils aren't installed in the
7414 SF compile farm, so library won't compile
7416 * device/lib/Makefile.in (version 1.56): initially I've added in
7417 target 'all' the prerequestive 'model-pic16' so it compiled the
7418 pic16 library, but now I've commented it out for the same reasons
7420 * added targets 'model-pic16' and 'objects-pic16' to compile the
7422 * added target 'port-specific-objects-pic16' to handle the
7423 generated libraries and copy them into the build/ directory
7424 * added target 'clean-intermediate-pic16' to clean intermediate
7425 files into pic16 directory
7426 * in target 'installdirs' added line to create directory pic16 in
7427 the installation path
7429 * device/include/Makefile.in (version 1.11): in target 'install'
7430 added lines to copy all header files to installation path,
7431 * in target 'installdirs' added line create directory for pic16
7432 headers in the installation path

7447 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7448 option so that it actually works. Made it specific to the z80, since
7449 the gbz80 doesn't have these kinds of I/O ports.

7477 via literal number. The symbol is placed in the corresponding
7478 position of the data ram
7479 * (pic16_dump_section): relocatable and absolute uninitialized
7480 data are now emitted in sorted order to reduce section naming,
7481 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7482 weren't marked as being in the access bank,
7484 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7486 Added portion of GNU PIC Library under the directory
7487 device/include/pic16 and device/lib/pic16. These files
7488 contain the declarations of SFRs for the PIC18Fxx2 devices.
7489 The directory is initialized via configure from toplevel.
7491 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

7519 all over. Telling LaTeX to be less strict with word spacing
7520 to better keep the right margin. Changed some notes about
7521 maintainance of the ports in section 3.2.1 - is it OK like this?
7523 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7561 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7563 * src/pic16/peeph.def: all peepholes with movff are commented out,
7564 because there is a problem in the pcode peep optimizer,
7565 * src/pic16/ralloc.c: the register allocator can now reuse local

7567 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7569 Added file src/pic16/NOTES with information about program writing on
7570 the current port version.

7602 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7605 * src/z80/main.c: added missed needLinkerScript flags (more than
7606 one port structure defined in these file)
7607 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7613 * src/port.h: added flag needLinkerScript in port->linker
7614 structure to inform whether to create a .lnk file or not,
7622 * src/z80/main.c: changed appropriately to configure
7623 needLinkerScript flag
7625 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7626 * src/pic/glue.c: added variable udata_section_name to
7627 override default uninitialized data segment definition for
7628 devices only with SHAREBANK memory (reported from Erik Epetrich)
7629 * (pic14emitOverlay): modified to emit a commented overlay segment
7630 directive when no overlay data exist
7631 * (picglue): modified to emit uninitialized data segment
7632 according to udata_section_name

7637 arguments via -W option
7638 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7639 object file from '.rel' to '.o' in port->linker structure,

7642 2004-01-07 Borut Razem <borut.razem AT siol.net>
7644 * support/scripts/sdcc.nsi: update PATH
7645 * support/scripts/sdcc.ico: craeted

7652 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7654 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
7656 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

7658 include information about variables allocated to the overlay
7661 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7663 * as/mcs51/lkmain.c: Help about -Y option

7675 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7677 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7678 (default behaviour).
7680 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7682 A python script to validate compiler diagnostic messages. It can be
7683 used to verify that sdcc complains about bad c source code and
7684 gives a good location of the error.
7685 * support/valdiag/Makefile,
7686 * support/valdiag/valdiag.py,
7687 * support/valdiag/tests/*
7689 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7691 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
7692 * src/SDCCsymt.c (newEnumType),

7702 * src/common.h: added ifndef/define/endif macros
7703 around the header file.
7704 Bug reported from Jesus Calvino-Fraga
7706 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7708 * sdcc.spec: updated
7709 * device/include/Makefile.in: don't install CVS directories
7710 * device/lib/Makefile.in: added removal of CVS directories after install
7711 * doc/Makefile: fixed install, added local_icons
7712 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7713 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7714 * src/ds390/gen.c (genRightShift): fixed bug #870788
7715 * src/SDCCast.c (decorateType): fixed bug #870781
7717 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7719 PIC16 port related changes:
7720 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7721 added variable stackPos,
7723 * gen.c: genCall, assignResultValue: added support for
7724 pushing/retrieving function parameters to/from stack,
7725 genFunction,genEndFunction: setup stack frame for the
7727 genAddrOf: will be changed according to bug 863624
7729 * added files genutils.c and genutils.h which contain gen*
7730 debugged and optimised functions extracted from gen.c
7732 * glue.c: added variable 'externs' which holds extern symbols,
7733 pic16emitRegularMap: is modified to properly handle relocatable
7734 symbols under the new scheme,
7735 pic16createInterruptVect: is modified
7736 pic16printPublics: is modified to emit 'global' assembler directives,
7737 added pic16_printExterns to print extern symbols,
7738 pic16glue: initializes stack/frame pointer in the beginning of
7739 the assembly output. Temporary hack, will be corrected later,
7740 because gplink yet does not support stack and SDCC does not
7741 yet support a type of crt0.o object to create the final binary.
7743 * Removed many lines that contain 8051 legacy code.
7744 * The code is finally placed under a 'code' directive.
7745 * Added port specific options.
7747 * _process_pragma: simplified since now we do not need *special*
7748 include file to define SFR registers. But a separate header
7749 will be needed. This will be developed later.
7750 * _pic16_parseOptions: added, parses port specific options:
7751 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7752 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7753 --preplace-udata-with=
7755 * _pic16_setDefaultOptions: modified to initialize section names,
7756 but hack is temporarly out of order since it needs improvement.
7757 * _pic16_genAssemblerPreamble: configuration words are emitted by
7758 their address instead of their name. This part is incomplete and
7759 supports only the 18Fxx2 devices. Other devices will emit an error
7760 during assembly since they do not contain the same set of config
7762 * _pic16_genIVT: is modified,
7764 * pcode.c: added definitions for some hardware registers that are needed
7766 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7767 All PCI entries are updated. Now LFSR is supported.
7768 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7769 * added pic16_newpCodeOpLit2 to support instructions with
7770 two literal arguments
7771 * pic16_pCode2str: corrected code that emits assembler instructions
7772 with two literal operands and those that have an access bit modifier
7773 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7774 this fixes a bug which caused some labels to be lost, when an
7775 assembler directive was added, i.e. banksel,
7776 * pic16_FixRegisterBanking: improved logic that causes the insertion
7778 * InlineFunction: functions that are called once, are not any more
7779 inlined. This can be a port option in the future,
7781 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7783 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7784 hold the corresponding uninitialized symbols,
7785 * pic16_allocProcessorRegister: registers have explicit marked the
7787 * pic16_allocInternalRegister: registers are explicit marked as
7789 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7790 processing list, so bit registers were lost,
7793 * ralloc.h: added field 'accessBank' and original symbol operand
7794 in register definition,
7795 * removed the field isMapped from register definition,
7797 ** Several functions have been removed from various sources:
7798 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7799 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7800 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7801 pic16_assignRelocatableRegisters
7803 ** others have been introduced:
7804 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7805 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7807 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7809 * support/scripts/inc2h.pl: changed definition of BIT_AT
7810 to emit 'sbit at' instead of 'bit at'. This was a request.
7812 PIC16 port related preliminary changes:
7813 * gen.c: prefixed function popRegFromString with
7814 pic16_ and all references to it corrected
7815 * pcode.c: all pic16_pc_* hardware registers prefixed
7816 with underscore (_),
7817 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7818 * ralloc.c: newReg(): when register is REG_SFR then
7819 set address to rIdx,
7820 pic16_allocProcessorRegister(): marks register wasUsed=0
7821 pic16_writeUsedRegs(): added a call to assign processor
7822 registers via pic16_assignFixedRegisters
7824 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7826 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7827 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7828 variables in unused register banks. Also the SSEG is placed
7829 wherever there is enough space for it, and IDATA can be anywhere
7830 in internal RAM. For now compile using -Wl-Y[stack_size].
7831 The mem file is different for this option as well, since it
7832 makes no sense of talking about DSEG lenght.
7834 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7836 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7837 in certain cases, e.g. when ROM assignment, patch provided
7838 from Albert den Haan.
7840 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8863 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8864 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8865 type for bits was changed. It resulted in bit variables becoming

8883 A few small changes that speed up the peephole optimizer.
8887 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8889 Try to make the peephole optimizer smarter by maintaining
8890 an association between the assembly source code and the
8891 iCodes that originated them. Put this information to use
8892 with a new peephole rule condition "notVolatile" so that
8893 the rules can be aggressive yet still safe.
8898 * src/mcs51/peeph.def
8900 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8904 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8905 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8906 if the left or right operand symbols have the accuse flag set.
8908 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8910 Changed the type of the result of the ! (NOT) operator to char;
8911 previously it returned the same type as the source. This allows
8912 us to eliminate all the genFloatNot functions (all of its target
8913 implementations were very buggy) since !float can use the same
8916 * src/SDCCicode.c (ast2iCode): ! returns char

8925 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8926 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8927 during interrupts. Ensure WSAVE is located at a shared bank address.
8928 2. Fixed page selection in some places
8929 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8930 the registers name strings.
8931 4. Fixed "signed / unsigned compare" compiler warnings.
8932 5. The PIC port manages its own allocation of the general purpose
8933 registers, but makes no attempt to reuse them. As a result when
8934 compiling it soon runs out of general purpose registers. Some
8935 additional code was added to the files pcode.c and device.c to walk

9022 omitted, the function will not automatically be given an entry
9023 in the interrupt vector table (similar to #pragma NOIV, but
9024 less syntacticly kludgy). The interrupt number is also now
9025 range checked. Also fixed a bug in the high order bit example

9528 * src/pic16/pcode.c: Cleaned warnings
9529 * src/pic16/pcodeflow.c: Cleaned warnings
9530 * src/pic16/pcoderegs.c: Cleaned warnings
9532 2003-05-19 Scott Dattalo <scott AT dattalo.com>
9534 * src/pic16/pcode.c: Cleaned warnings
9535 * src/pic16/pcodepeep.c: Cleaned warnings
9536 * src/pic16/ralloc.c: Cleaned warnings
9538 2003-05-19 Bernhard Held <bernhard AT bernhardheld.de>
9540 * doc/sdccman.lyx: fixed bug 739745
9541 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
9543 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9545 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9546 it can be defined with CFLAGS when running configure
9547 * src/SDCCmain.c: fixed compiling + linking with object files
9549 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9551 * configure.in: configure for pic16 port,
9552 added --disable-pic16-port
9553 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9554 * src/SDCCmain.c: linkOptions is changed to set *,
9555 added if/endif conditional macros to remove options help
9556 messages from optionsTable when a port is not configured, added
9557 support for the PIc16 port in the ports table, when executing
9558 the compiler with no port specified on command line, a default
9559 port is selected with the new macro DEFAULT_PORT which is
9560 defined in port.h, in setDefaultOptions() linkOptions is removed
9561 from initialization assignment, since now it is a set,
9562 parseCmdLine uses setParseWithComma for linkOptions, in
9563 linkEdit() linkOptions are accessed with new function indexSet()
9564 which returns the i'th item of a set variable. See SDCCset.c, in
9565 linkEdit() when calling buildCmdLine(), added linkOptions as
9566 last argument. Now users can pass arguments to gplink via the
9567 -Wl option, main() uses pic16glue() to glue up pic16 programs
9568 * src/SDCCpeeph.c: various changes to support pic16
9569 * src/SDCCset.c: added function void *indexSet(set *, int) to
9570 return the i'th item of the set

9572 * src/SDCCsymt.c: in checkSClass(), added support for PIC16
9573 * src/clean.mk: added pic16 in CLEANALLPORTS variable
9574 * src/port.h: added TARGET_ID_PIC16,TARGET_IS_PIC16 macro,
9575 added macro DEFAULT_PORT
9576 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
9577 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
9579 * src/pic16/glue.c: commented out some error producing lines
9580 * src/pic16/main.c: __config directives are commented out to stop
9581 gpasm complaining and test the linkage with gplink, _linkCmd and
9582 _asmCmd changed to be more gplink and gpasm friendly
9583 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9584 produced an error when parsed, peep rule 12 is added to utilize
9585 movff, but it is commented out since the pCode does not support
9586 yet a command with 2 address arguments
9588 2003-05-18 <johan AT balder>
9590 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9591 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9615 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9617 2003-05-11 Borut Razem <borut.razem AT siol.net>
9619 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9620 the path of bin directory, so that PATH is the only env. variable, which has to be set
9621 in case of standard installation.

10648 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10649 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10651 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10653 * in \sdcc\as\mcs51\ changed these files in order to create an
10654 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10655 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10656 following files to include the previous two files: aslink.dsp,
10657 Makefile.aslink, Makefile.bcc, and Makefile.in.
10659 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10660 .adb instead of .cdb
10662 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10664 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10665 value from option --iram-size.
10667 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10669 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10672 2002-09-18 <wiml AT hhhh.org>
10674 * SDCClrange.h: exposed setFromRange() and setToRange()
10675 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10676 packRegsForAccUse() (bug 542397)
10677 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10678 multiple times and emitting the fetch operations more than once
10679 added aopGetUsesAcc() function to allow binary operators to
10680 fetch their operands in the correct order; made genMinus() emit
10681 compact code for X = LITERAL - Y
10683 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10684 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10685 sprintf() in line 1267.
10687 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10688 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10691 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10692 Changes to aslink (All the changes are marked with 'JCF'):
10694 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10697 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10698 area BSEG. Also moves, if possible, the DATA area down into the internal
10699 ram so more space is available.
10701 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10704 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10705 not bytes. Function summary() which creates a memory usage summary
10706 file with extension .mem. Reports of overlaping stack and small stack
10707 size. If the space for the stack is less than 16 bytes aslink trows a
10710 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10711 the 8051. Option 'y' for memory summary output file.
10713 Changes to sdcc (All the changes are marked with 'JCF'):
10715 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10717 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10718 overlaying area for it (uses RegBankUsed[4]).
10720 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10721 bank zero as used by default. By default aslink locates the stack
10722 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10723 the creation of the .mem file. Delegates the allocation of data area
10724 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10725 the begining of the stack area to aslink.
10727 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10728 glue() in SDCCglue.c creates an area for it.
10730 2002-09-03 Borut Razem <borut.razem AT siol.net>
10731 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10732 sdcc/src/pic/glue.c:
10733 introduced atexit() handler for teporay files removal in case of
10734 errors, assertions, ...
10736 2002-08-29 Borut Razem <borut.razem AT siol.net>
10737 * sdcc/support/cpp2/auto-host_vc_in.h:
10738 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10739 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10740 Maybe there is a similar problem with BORLANDC? It should be checked!
10742 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10743 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10744 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10745 was not executed, and the compiler (cl) launched a warning:
10746 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10748 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10749 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10751 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10752 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10754 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10755 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10756 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10757 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10758 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10759 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10760 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10761 - added Release configuration in VS projects
10762 - review of compiler an linker options
10763 - VC .exe files are generated in bin_vc directory, not to interfere
10764 with binaries generated from other projects (cygwin, mingw, bcc ...)
10766 * sdcc/src/yacc.dsp: added
10768 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10769 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10770 and insert the version number definitions from .version
10772 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10774 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10775 added - genarate auto-host.h using auto-host_vc_in.h as template
10778 removed from CVS, generated automatically
10780 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10781 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10783 2002-08-11 Borut Razem <borut.razem AT siol.net>
10784 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10786 2002-08-10 Borut Razem <borut.razem AT siol.net>
10787 * src/SDCCmain.c (main):
10788 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10789 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10790 The consequence was that some temporary files were not removed.
10793 unification of code in functions tempfilename() and tempfile():
10794 function tempnam() is defined in Visual Studio 6.0 and .NET
10796 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10798 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10799 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10800 - removed compiler command line option /WX: Treats all warnings as errors
10801 - update a list of source files, included into the project
10803 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,

10820 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10821 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10822 - solved MSC error in function aopDump()

11002 Previous fix was not good. basic blocks that have "break" or "return" are
11003 not really partof a loop , but live ranges used in these blocks should
