759 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
761 Enabled VPATH feature: changed nearly all Makefiles (149 files).
762 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
764 One basic decision: e.g. src/clean.mk includes further files. In order
765 to make this work there are two solutions:
766 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
767 run configure on them. This way they can use
768 'include $(srcdir)/port-clean.mk'
769 - always include clean.mk by the Makefile at the same level. To avoid
770 that `make clean` tries to include and build Makefile.dep the
771 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
772 implemented, because now even `make uninstall` doesn't create
773 Makefile.in. clean.mk could be eliminated by pasting it in
776 * debugger/mcs51/Makefile.in: build own objects from library sources
777 (SLIB, SDCC) in current directory
779 * configure, configure.in: renamed --disable-device-lib-build in
780 --disable-device-lib; added --enable-doc, the required tools are
781 searched by configure; added result message; the toolchain for the
782 belonging ports are now only built, if the port is enabled.
784 * support/regression/*: all output is written in directory gen, because
785 the fwk and ports directories don't livet in the build tree using vpath
787 * doc/sdccman.lyx: renamed --disable-device-lib-build to
788 --disable-device-lib, added --enable-doc, added section VPATH
790 * sim/ucsim/configure.in,
791 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
792 z80 are enabled by default
794 2006-04-24 Raphael Neider <rneider AT web.de>
796 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
797 to config word, "pic14_"-prefixed some extern functions
798 (pic14_emitConfigWord): emit __config directive(s) if assignment to
799 config word has been found
800 * src/pic/device.h: added prototypes
801 * src/pic/pcode.c: added "pic14_"-prefix where needed
802 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
804 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
806 (pic14emitRegularMap): ignore config words,
807 (pic14createInterruptVect): moved generating __config directives away
808 (picglue): have __config directives emitted
810 2006-04-24 Borut Razem <borut.razem AT siol.net>

818 fixes #1469504 and #1474602,
819 (pCodeRegOptimizeRegUsage): fixed typo in comment

1065 implemented patch 1120823 Thanks to Willy De la Court (normal
1066 interrupts need an interrupt number now if they are made critical),
1067 and enabled nesting of critical functions though not for gbz80
1068 (genCritical, genEndCritical): added functions
1069 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1070 * src/z80/mappings.i: added "ei" to all mappings

1082 the left operand is shorter than the result (c* = lit-c* + int),
1084 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1087 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1089 * src/.version: increased version number to 2.5.5
1090 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1091 linking is done manually in pic16 port's _linkEdit,
1092 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1093 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1094 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1095 allocate asmop as AOP_ACC,
1096 (aopForRemat): added parameter 'bool result' in function declaration,
1097 (pic16_aopGet): return AOP_ACC when accessing WREG,
1098 (pic16_popGetTempReg): minor modification,

1109 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1110 call to allocReg, not by manually allocating a new one,
1111 (pic16_assignRegisters): now before going through the register
1112 allocating functions mark all registers as free. This eliminates some
1113 side effects resulting from peephole parser done earlier in the backbone
1115 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1165 2006-03-06 Borut Razem <borut.razem AT siol.net>
1167 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1168 made the linker quiet
1170 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1172 * src/pic16/gen.c (genPcall): fixed bug #1443644
1173 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1174 which dumps before the function entry point a data byte which represents
1175 the number of the local variables used by the specified function, added
1176 'xinst' for initial support for Extended Instruction Support,
1177 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1178 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1179 port->fun_prefix anymore (may change later),
1180 (genFunction, genEndFunction): do not store/restore local registers for
1181 _main (this should take care the --main-return command line option in
1183 (genOr): removed some legacy pic-port instructions,
1184 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1185 performing operations with SFR's causes data to be written more than
1186 once to each SFR. Perhaps SFRs should be handled in special cases...
1187 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1189 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1190 into account for stack starting position,

1192 --extended or -y for Extended Instruction Support,
1193 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1194 (deassignLRs): *** perhaps the most important change, old 'for' code
1195 (commented out for reference), didn't account for some registers which
1196 were left marked 'not free' after a pointer operation. The change
1197 reduces register usage a lot in some cases
1199 2006-03-04 Borut Razem <borut.razem AT siol.net>
1201 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3463 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
3464 on rIfx (genCmp was broken)
3466 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3468 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3469 * src/z80/main.c (_keywords[]),
3470 * src/SDCCglobal.h (struct options),
3472 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3473 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3474 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3475 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3476 always available in leading double underscore form. The C99 support is
3477 mostly missing, but it's a start.
3478 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3479 reserved identifier "__data".
3481 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3483 * src/mcs51/peeph.def: fixed bug 1170013
3485 2005-03-22 Maarten Brock <sourceforge.brock AT dse.nl>

3491 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
3494 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3496 * src/port.h (struct PORT),
3497 * src/avr/ralloc.c (avr_assignRegisters),
3499 * src/ds390/ralloc.c (ds390_assignRegisters),
3501 * src/hc08/ralloc.c (hc08_assignRegisters),

3523 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
3524 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3525 immedDom() returning wrong block; probably fixes bug #1160833)
3527 2005-03-20 Borut Razem <borut.razem AT siol.net>
3529 * support/scripts/inc2h.pl: WIN32 port
3531 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3533 * device/lib/makefile.in: added abs.c and labs.c
3535 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3537 * device/include/stdint.h: added
3538 * device/lib/abs.c: added
3539 * device/lib/labs.c: added
3540 * device/include/stdlib.h: added abs() and labs() prototypes

3555 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3557 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3559 * device/lib/printf_large.c: removed inline assembly for portability and
3560 readability. Use printf_fast if speed or size are more important.
3561 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3562 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3564 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3566 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3567 prevent compiler warning
3569 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3571 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3572 moved to level 0 and declared as static. Also they are explicit
3573 placed in access bank. This was necessery because some times they
3574 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3575 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3576 optimizations. Currently only compare to unsigned char is implemented,
3577 * src/pic16/gen.c: added fReturnIdx array,
3578 * (struct resolvedIfx) is moved to gen.h and made public,
3579 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3580 * (aopForSym): added an optimization to directly store in stack of
3581 the operand of a SEND iCode,
3582 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3583 but as registers instead (AOP_REG) using the fReturnIdx array,
3584 * (pic16_freeAsmop): remove the freed register from the
3585 _G.sregsAlloc field,
3586 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3587 a compare of 'WREG',
3588 * (pic16_popGetTempRegCond): changed function prototype, now
3589 function takes also a bitVector argument v which holds the current
3590 set of registers that are allocated for stack access by aopForSym,
3591 registers allocated in aopForSym for accessing stack symbols are not
3592 any more part of the functions usedRegs field,
3593 * (genCall): some times aopOp is called for a stack variable to be
3594 send, aopForSym might perform the push, if this is true make sure
3595 that genCall doesn't push the variable twice by testing _G.resDirect,
3596 * (genFunction): changed testing for unspecified interrupt number
3597 from 256 to INTNO_UNSPEC,
3598 * modified selection scheme of frame pointer generation. Previously
3599 if function did use local registers a frame pointer was generated,
3600 now a frame pointer is generated only if function has arguments
3601 (that need PLUSW2 register access), or has stack arguments, or the
3602 compiler is not instructed to omit the frame pointer,
3603 * (genEndFunction): before restoring local registers that were saved
3604 in the function preamble, also restore the registers that *might*
3605 have been allocated for stack access,
3606 * (genRet): removed some old comments,
3607 * (genCmp, the active (RN's) version): added a call to the
3608 pic16_genCmp_special function to perform the compare with a more
3609 robust and optimized way,
3610 * (genInline): a feature has been added in inline code generation,
3611 which allows a wildcard variable substitution when writing inline
3612 assembly. Code is incomplete and experimental therefore undocumented,
3613 * (genCast): changed order of aopOp for result and right to allow
3614 aopForSym to directly load the result if possible,
3615 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3616 perform an optimized compare on some selected special occasions,
3617 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3618 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3619 generate an IVT any more,
3620 * src/pic16/main.c (pic16_optionsTable): added command line option
3622 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3623 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3625 * src/pic16/NOTES: Raphael Neider added in list of active developers
3626 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3627 jumptable_end to prevent bug #,
3628 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3629 inCond and outCond fields,
3630 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3631 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3632 turn off register spilling,
3633 * (packRegsForOneUse): synced with other ports' versions although it
3634 is not used currently,
3635 * (pic16_packRegisters): added an optimization while reading
3636 structure bitfields, some registers may be saved (malloc code is
3637 decreased by 80 bytes)
3639 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3641 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3642 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3643 this can be optimized more?
3645 2005-03-10 Raphael Neider <rneider AT web.de>
3647 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3648 genNearPointerGet): (hopefully) fixed access to bitfields via
3649 pointers (p->bitN = x; and x = p->bitN; failed)
3651 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3838 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3839 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3840 this might fix SIGSEGVs on MinGW...
3841 * src/SDCCopt.c (killDeadCode): restored original behaviour
3842 (volatile operands might get thrown away though)
3844 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

4283 Adding support for replacing ljmps with sjmps in jumptables
4284 generated for switch statements. For now you need to set the
4285 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4286 Now 4 algorithms for mcs51 jumptable generation are used:
4287 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4288 addresses loaded pc-relative for up to 112 cases and stack-pushing
4289 target addresses loaded with offset from dptr for up to 256 cases.

4316 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4317 to call when a stack overflow occurs,
4318 * (malloc.h): added CVS Id tag,
4319 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4321 * added libc directory. The current version of LibC contains string
4322 functions, ctype functions and macros and some functions of the
4323 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4324 be extensively tested in the future. Standard disclaimer here.
4325 Library is not automatically build yet. But one can build it by
4326 invoking 'make' inside the libc directory.
4327 * added ADC library under libio. Preliminary version yet.
4329 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4332 * (pic16_popGetTempReg): removed warning messgae when allocating
4333 temporary registers, its a buggy feature and will be removed,
4334 * (pic16_popGet): set register instance field in AOP_CRY,
4335 * (pic16_outBitC): fixed for results in size greater than 1,
4336 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4337 * (pic16_storeForReturn): optimized return of 0,
4338 * (genCmp): experimental code for new genCmp which uses PIC18's

7367 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7369 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7370 loaded with the linker search paths (-L arguments) and the libraries
7371 to be linked with the current source (-l arguments). Changes
7372 currently will affect only the pic16 port.
7373 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7374 include path the port specific paths and port specific libraries,
7375 * gplink command now contains the $3 argument,
7376 * src/pic16/device.h,
7377 * src/pic16/device.c,: structure PIC_device is made public and
7378 renamed to PIC16_device, the same for variable Pics which is renamed

7393 Documenting changes from previous commits.
7394 * configure.in (version 1.56),
7395 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7396 when generating output files to configure the pic16 library,
7397 but now I've commented it out, since gputils aren't installed in the
7398 SF compile farm, so library won't compile
7400 * device/lib/Makefile.in (version 1.56): initially I've added in
7401 target 'all' the prerequestive 'model-pic16' so it compiled the
7402 pic16 library, but now I've commented it out for the same reasons
7404 * added targets 'model-pic16' and 'objects-pic16' to compile the
7406 * added target 'port-specific-objects-pic16' to handle the
7407 generated libraries and copy them into the build/ directory
7408 * added target 'clean-intermediate-pic16' to clean intermediate
7409 files into pic16 directory
7410 * in target 'installdirs' added line to create directory pic16 in
7411 the installation path
7413 * device/include/Makefile.in (version 1.11): in target 'install'
7414 added lines to copy all header files to installation path,
7415 * in target 'installdirs' added line create directory for pic16
7416 headers in the installation path

7431 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7432 option so that it actually works. Made it specific to the z80, since
7433 the gbz80 doesn't have these kinds of I/O ports.
7435 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7437 * device/include/z180.h,

7461 via literal number. The symbol is placed in the corresponding
7462 position of the data ram
7463 * (pic16_dump_section): relocatable and absolute uninitialized
7464 data are now emitted in sorted order to reduce section naming,
7465 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7466 weren't marked as being in the access bank,
7468 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7470 Added portion of GNU PIC Library under the directory
7471 device/include/pic16 and device/lib/pic16. These files
7472 contain the declarations of SFRs for the PIC18Fxx2 devices.
7473 The directory is initialized via configure from toplevel.
7475 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

7503 all over. Telling LaTeX to be less strict with word spacing
7504 to better keep the right margin. Changed some notes about
7505 maintainance of the ports in section 3.2.1 - is it OK like this?
7507 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7544 UPPER for immediate operands,
7545 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7547 * src/pic16/peeph.def: all peepholes with movff are commented out,
7548 because there is a problem in the pcode peep optimizer,
7549 * src/pic16/ralloc.c: the register allocator can now reuse local

7551 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7553 Added file src/pic16/NOTES with information about program writing on
7554 the current port version.

7586 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7589 * src/z80/main.c: added missed needLinkerScript flags (more than
7590 one port structure defined in these file)
7591 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7607 needLinkerScript flag
7609 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7610 * src/pic/glue.c: added variable udata_section_name to
7611 override default uninitialized data segment definition for

7613 * (pic14emitOverlay): modified to emit a commented overlay segment
7614 directive when no overlay data exist
7615 * (picglue): modified to emit uninitialized data segment
7616 according to udata_section_name

7621 arguments via -W option
7622 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7623 object file from '.rel' to '.o' in port->linker structure,

7626 2004-01-07 Borut Razem <borut.razem AT siol.net>
7628 * support/scripts/sdcc.nsi: update PATH
7629 * support/scripts/sdcc.ico: craeted

7636 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7638 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
7640 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

7642 include information about variables allocated to the overlay
7645 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7647 * as/mcs51/lkmain.c: Help about -Y option

7659 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7661 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7662 (default behaviour).
7664 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7666 A python script to validate compiler diagnostic messages. It can be
7667 used to verify that sdcc complains about bad c source code and
7668 gives a good location of the error.
7669 * support/valdiag/Makefile,
7670 * support/valdiag/valdiag.py,
7671 * support/valdiag/tests/*
7673 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7675 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

7686 * src/common.h: added ifndef/define/endif macros
7687 around the header file.
7688 Bug reported from Jesus Calvino-Fraga
7690 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7692 * sdcc.spec: updated
7693 * device/include/Makefile.in: don't install CVS directories
7694 * device/lib/Makefile.in: added removal of CVS directories after install
7695 * doc/Makefile: fixed install, added local_icons
7696 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7697 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7698 * src/ds390/gen.c (genRightShift): fixed bug #870788
7699 * src/SDCCast.c (decorateType): fixed bug #870781
7701 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7703 PIC16 port related changes:
7704 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7705 added variable stackPos,
7707 * gen.c: genCall, assignResultValue: added support for
7708 pushing/retrieving function parameters to/from stack,
7709 genFunction,genEndFunction: setup stack frame for the
7711 genAddrOf: will be changed according to bug 863624
7713 * added files genutils.c and genutils.h which contain gen*
7714 debugged and optimised functions extracted from gen.c
7716 * glue.c: added variable 'externs' which holds extern symbols,
7717 pic16emitRegularMap: is modified to properly handle relocatable
7718 symbols under the new scheme,
7719 pic16createInterruptVect: is modified
7720 pic16printPublics: is modified to emit 'global' assembler directives,
7721 added pic16_printExterns to print extern symbols,
7722 pic16glue: initializes stack/frame pointer in the beginning of
7723 the assembly output. Temporary hack, will be corrected later,
7724 because gplink yet does not support stack and SDCC does not
7725 yet support a type of crt0.o object to create the final binary.
7727 * Removed many lines that contain 8051 legacy code.
7728 * The code is finally placed under a 'code' directive.
7729 * Added port specific options.
7731 * _process_pragma: simplified since now we do not need *special*
7732 include file to define SFR registers. But a separate header
7733 will be needed. This will be developed later.
7734 * _pic16_parseOptions: added, parses port specific options:
7735 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7736 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7737 --preplace-udata-with=
7739 * _pic16_setDefaultOptions: modified to initialize section names,
7740 but hack is temporarly out of order since it needs improvement.
7741 * _pic16_genAssemblerPreamble: configuration words are emitted by
7742 their address instead of their name. This part is incomplete and
7743 supports only the 18Fxx2 devices. Other devices will emit an error
7744 during assembly since they do not contain the same set of config
7746 * _pic16_genIVT: is modified,
7748 * pcode.c: added definitions for some hardware registers that are needed
7750 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7751 All PCI entries are updated. Now LFSR is supported.
7752 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7753 * added pic16_newpCodeOpLit2 to support instructions with
7754 two literal arguments
7755 * pic16_pCode2str: corrected code that emits assembler instructions
7756 with two literal operands and those that have an access bit modifier
7757 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7758 this fixes a bug which caused some labels to be lost, when an
7759 assembler directive was added, i.e. banksel,
7760 * pic16_FixRegisterBanking: improved logic that causes the insertion
7762 * InlineFunction: functions that are called once, are not any more
7763 inlined. This can be a port option in the future,
7765 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7767 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7768 hold the corresponding uninitialized symbols,
7769 * pic16_allocProcessorRegister: registers have explicit marked the
7771 * pic16_allocInternalRegister: registers are explicit marked as
7773 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7774 processing list, so bit registers were lost,
7777 * ralloc.h: added field 'accessBank' and original symbol operand
7778 in register definition,
7779 * removed the field isMapped from register definition,
7781 ** Several functions have been removed from various sources:
7782 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7783 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7784 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7785 pic16_assignRelocatableRegisters
7787 ** others have been introduced:
7788 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7789 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7791 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7793 * support/scripts/inc2h.pl: changed definition of BIT_AT
7794 to emit 'sbit at' instead of 'bit at'. This was a request.
7796 PIC16 port related preliminary changes:
7797 * gen.c: prefixed function popRegFromString with
7798 pic16_ and all references to it corrected
7799 * pcode.c: all pic16_pc_* hardware registers prefixed
7800 with underscore (_),
7801 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7802 * ralloc.c: newReg(): when register is REG_SFR then
7803 set address to rIdx,
7804 pic16_allocProcessorRegister(): marks register wasUsed=0
7805 pic16_writeUsedRegs(): added a call to assign processor
7806 registers via pic16_assignFixedRegisters
7808 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7810 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7811 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7812 variables in unused register banks. Also the SSEG is placed
7813 wherever there is enough space for it, and IDATA can be anywhere
7814 in internal RAM. For now compile using -Wl-Y[stack_size].
7815 The mem file is different for this option as well, since it
7816 makes no sense of talking about DSEG lenght.
7818 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7820 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7821 in certain cases, e.g. when ROM assignment, patch provided
7822 from Albert den Haan.
7824 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7967 * src/mcs51/peephole.def,
7968 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
7969 (allows non-interrupt and interrupt code to safely compete for a resource
7970 without the non-interrupt code having to disable interrupts)
7972 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7974 * src/SDCCicode.c (geniCodeAdd),

7994 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7996 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165
7998 2003-12-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8067 it breaks with bitfields, extern declarations, and gcse analysis.
8068 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8069 could be assigned through a pointer, so don't complain.

8847 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8848 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8849 type for bits was changed. It resulted in bit variables becoming

8867 A few small changes that speed up the peephole optimizer.
8871 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8873 Try to make the peephole optimizer smarter by maintaining
8874 an association between the assembly source code and the
8875 iCodes that originated them. Put this information to use
8876 with a new peephole rule condition "notVolatile" so that
8877 the rules can be aggressive yet still safe.
8882 * src/mcs51/peeph.def
8884 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8888 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8889 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8890 if the left or right operand symbols have the accuse flag set.
8892 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8894 Changed the type of the result of the ! (NOT) operator to char;
8895 previously it returned the same type as the source. This allows
8896 us to eliminate all the genFloatNot functions (all of its target
8897 implementations were very buggy) since !float can use the same

8909 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8910 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8911 during interrupts. Ensure WSAVE is located at a shared bank address.
8912 2. Fixed page selection in some places
8913 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8914 the registers name strings.
8915 4. Fixed "signed / unsigned compare" compiler warnings.
8916 5. The PIC port manages its own allocation of the general purpose
8917 registers, but makes no attempt to reuse them. As a result when
8918 compiling it soon runs out of general purpose registers. Some
8919 additional code was added to the files pcode.c and device.c to walk
8920 through the function call tree and rename the registers so that they
8930 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8937 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8939 Made bitfield a distinct type from bit so that bitfields
8940 convert as per ANSI C and bits retain their traditional
8941 boolean style behaviour. Implemented bitfield support in
8949 * src/ds390/gen.c: bit v bitfield split
8950 * src/z80/gen.c: New support for bitfields
8951 * support/regression/tests/bitfields.c: reenabled z80,
8954 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9005 Made the constant following the "interrupt" keyword optional. If
9006 omitted, the function will not automatically be given an entry
9007 in the interrupt vector table (similar to #pragma NOIV, but
9008 less syntacticly kludgy). The interrupt number is also now
9009 range checked. Also fixed a bug in the high order bit example

9531 * src/SDCCmain.c: fixed compiling + linking with object files
9533 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9535 * configure.in: configure for pic16 port,
9536 added --disable-pic16-port
9537 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9538 * src/SDCCmain.c: linkOptions is changed to set *,
9539 added if/endif conditional macros to remove options help
9540 messages from optionsTable when a port is not configured, added
9541 support for the PIc16 port in the ports table, when executing
9542 the compiler with no port specified on command line, a default
9543 port is selected with the new macro DEFAULT_PORT which is
9544 defined in port.h, in setDefaultOptions() linkOptions is removed
9545 from initialization assignment, since now it is a set,
9546 parseCmdLine uses setParseWithComma for linkOptions, in
9547 linkEdit() linkOptions are accessed with new function indexSet()
9548 which returns the i'th item of a set variable. See SDCCset.c, in
9549 linkEdit() when calling buildCmdLine(), added linkOptions as
9550 last argument. Now users can pass arguments to gplink via the
9551 -Wl option, main() uses pic16glue() to glue up pic16 programs

9563 * src/pic16/glue.c: commented out some error producing lines
9564 * src/pic16/main.c: __config directives are commented out to stop
9565 gpasm complaining and test the linkage with gplink, _linkCmd and
9566 _asmCmd changed to be more gplink and gpasm friendly
9567 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9568 produced an error when parsed, peep rule 12 is added to utilize
9569 movff, but it is commented out since the pCode does not support
9570 yet a command with 2 address arguments
9572 2003-05-18 <johan AT balder>

9601 2003-05-11 Borut Razem <borut.razem AT siol.net>
9603 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

10632 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10633 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10635 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10637 * in \sdcc\as\mcs51\ changed these files in order to create an
10638 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10639 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10640 following files to include the previous two files: aslink.dsp,
10641 Makefile.aslink, Makefile.bcc, and Makefile.in.
10643 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10644 .adb instead of .cdb
10646 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10648 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10649 value from option --iram-size.
10651 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10653 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10656 2002-09-18 <wiml AT hhhh.org>
10658 * SDCClrange.h: exposed setFromRange() and setToRange()
10659 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10660 packRegsForAccUse() (bug 542397)
10661 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10662 multiple times and emitting the fetch operations more than once
10663 added aopGetUsesAcc() function to allow binary operators to
10664 fetch their operands in the correct order; made genMinus() emit
10665 compact code for X = LITERAL - Y
10667 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10668 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10669 sprintf() in line 1267.
10671 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10672 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10675 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10676 Changes to aslink (All the changes are marked with 'JCF'):
10678 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10681 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10682 area BSEG. Also moves, if possible, the DATA area down into the internal
10683 ram so more space is available.
10685 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10688 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10689 not bytes. Function summary() which creates a memory usage summary
10690 file with extension .mem. Reports of overlaping stack and small stack
10691 size. If the space for the stack is less than 16 bytes aslink trows a
10694 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10695 the 8051. Option 'y' for memory summary output file.
10697 Changes to sdcc (All the changes are marked with 'JCF'):
10699 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10701 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10702 overlaying area for it (uses RegBankUsed[4]).
10704 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10705 bank zero as used by default. By default aslink locates the stack
10706 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10707 the creation of the .mem file. Delegates the allocation of data area
10708 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10709 the begining of the stack area to aslink.
10711 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10712 glue() in SDCCglue.c creates an area for it.
10714 2002-09-03 Borut Razem <borut.razem AT siol.net>
10715 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10716 sdcc/src/pic/glue.c:
10717 introduced atexit() handler for teporay files removal in case of
10718 errors, assertions, ...
10720 2002-08-29 Borut Razem <borut.razem AT siol.net>
10721 * sdcc/support/cpp2/auto-host_vc_in.h:
10722 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10723 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10724 Maybe there is a similar problem with BORLANDC? It should be checked!
10726 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10727 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10728 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10729 was not executed, and the compiler (cl) launched a warning:
10730 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10732 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10733 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10735 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10736 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10738 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10739 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10740 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10741 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10742 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10743 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10744 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10745 - added Release configuration in VS projects
10746 - review of compiler an linker options
10747 - VC .exe files are generated in bin_vc directory, not to interfere
10748 with binaries generated from other projects (cygwin, mingw, bcc ...)
10750 * sdcc/src/yacc.dsp: added
10752 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10753 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10754 and insert the version number definitions from .version
10756 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10758 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10759 added - genarate auto-host.h using auto-host_vc_in.h as template
10762 removed from CVS, generated automatically
10764 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10765 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10767 2002-08-11 Borut Razem <borut.razem AT siol.net>
10768 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10770 2002-08-10 Borut Razem <borut.razem AT siol.net>
10771 * src/SDCCmain.c (main):
10772 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10773 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10774 The consequence was that some temporary files were not removed.
10777 unification of code in functions tempfilename() and tempfile():
10778 function tempnam() is defined in Visual Studio 6.0 and .NET
10780 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10782 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10783 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10784 - removed compiler command line option /WX: Treats all warnings as errors
10785 - update a list of source files, included into the project
10787 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10788 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10789 changed project type to Generic Project so that can be correcly converted to VS.NET project
10791 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10793 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10795 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10797 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10798 added return 0 statements after assert() to make compiler happy
10800 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10801 added newline in the def file to keep MSC compiler satisfied
10803 * sdcc/src/z80/gen.c:
10804 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
