825 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
827 Enabled VPATH feature: changed nearly all Makefiles (149 files).
828 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
830 One basic decision: e.g. src/clean.mk includes further files. In order
831 to make this work there are two solutions:
832 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
833 run configure on them. This way they can use
834 'include $(srcdir)/port-clean.mk'
835 - always include clean.mk by the Makefile at the same level. To avoid
836 that `make clean` tries to include and build Makefile.dep the
837 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
838 implemented, because now even `make uninstall` doesn't create
839 Makefile.in. clean.mk could be eliminated by pasting it in
842 * debugger/mcs51/Makefile.in: build own objects from library sources
843 (SLIB, SDCC) in current directory
845 * configure, configure.in: renamed --disable-device-lib-build in
846 --disable-device-lib; added --enable-doc, the required tools are
847 searched by configure; added result message; the toolchain for the
848 belonging ports are now only built, if the port is enabled.
850 * support/regression/*: all output is written in directory gen, because
851 the fwk and ports directories don't livet in the build tree using vpath
853 * doc/sdccman.lyx: renamed --disable-device-lib-build to
854 --disable-device-lib, added --enable-doc, added section VPATH
856 * sim/ucsim/configure.in,
857 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
858 z80 are enabled by default
860 2006-04-24 Raphael Neider <rneider AT web.de>
862 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
863 to config word, "pic14_"-prefixed some extern functions
864 (pic14_emitConfigWord): emit __config directive(s) if assignment to
865 config word has been found
866 * src/pic/device.h: added prototypes
867 * src/pic/pcode.c: added "pic14_"-prefix where needed
868 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
870 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
872 (pic14emitRegularMap): ignore config words,
873 (pic14createInterruptVect): moved generating __config directives away
874 (picglue): have __config directives emitted
876 2006-04-24 Borut Razem <borut.razem AT siol.net>
878 * doc/Makefile: sync with nightly build makefile

883 registers that have not been assigned proper liveranges,
884 fixes #1469504 and #1474602,
885 (pCodeRegOptimizeRegUsage): fixed typo in comment
887 2006-04-24 Borut Razem <borut.razem AT siol.net>
889 * device/examples/main8051.c: deleted - it was removed from CVS
890 24.mar.2000 and after that modified 18.feb.2001, so it reappered
891 after the transition to Subversion
892 * src/SDCCalloc.h: deleted - it was removed from CVS
893 3.feb.2001 and after that modified 18.feb.2001, so it reappered
894 after the transition to Subversion

1131 implemented patch 1120823 Thanks to Willy De la Court (normal
1132 interrupts need an interrupt number now if they are made critical),
1133 and enabled nesting of critical functions though not for gbz80
1134 (genCritical, genEndCritical): added functions
1135 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1136 * src/z80/mappings.i: added "ei" to all mappings

1148 the left operand is shorter than the result (c* = lit-c* + int),
1150 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1153 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1155 * src/.version: increased version number to 2.5.5
1156 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1157 linking is done manually in pic16 port's _linkEdit,
1158 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1159 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1160 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1161 allocate asmop as AOP_ACC,
1162 (aopForRemat): added parameter 'bool result' in function declaration,
1163 (pic16_aopGet): return AOP_ACC when accessing WREG,
1164 (pic16_popGetTempReg): minor modification,

1175 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1176 call to allocReg, not by manually allocating a new one,
1177 (pic16_assignRegisters): now before going through the register
1178 allocating functions mark all registers as free. This eliminates some
1179 side effects resulting from peephole parser done earlier in the backbone
1181 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1239 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1240 which dumps before the function entry point a data byte which represents
1241 the number of the local variables used by the specified function, added
1242 'xinst' for initial support for Extended Instruction Support,
1243 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1244 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1245 port->fun_prefix anymore (may change later),
1246 (genFunction, genEndFunction): do not store/restore local registers for
1247 _main (this should take care the --main-return command line option in
1249 (genOr): removed some legacy pic-port instructions,
1250 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1251 performing operations with SFR's causes data to be written more than
1252 once to each SFR. Perhaps SFRs should be handled in special cases...
1253 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1255 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1256 into account for stack starting position,
1257 (struct OPTIONS pic16_optionsTable): added command line argument
1258 --extended or -y for Extended Instruction Support,
1259 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1260 (deassignLRs): *** perhaps the most important change, old 'for' code
1261 (commented out for reference), didn't account for some registers which
1262 were left marked 'not free' after a pointer operation. The change
1263 reduces register usage a lot in some cases
1265 2006-03-04 Borut Razem <borut.razem AT siol.net>
1267 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3532 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3534 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

3538 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3539 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3540 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3541 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3542 always available in leading double underscore form. The C99 support is
3543 mostly missing, but it's a start.
3544 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3545 reserved identifier "__data".
3547 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3593 2005-03-20 Borut Razem <borut.razem AT siol.net>
3595 * support/scripts/inc2h.pl: WIN32 port

3623 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3625 * device/lib/printf_large.c: removed inline assembly for portability and
3626 readability. Use printf_fast if speed or size are more important.
3627 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3628 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3630 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3632 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3633 prevent compiler warning
3635 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3637 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3638 moved to level 0 and declared as static. Also they are explicit
3639 placed in access bank. This was necessery because some times they
3640 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3641 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3642 optimizations. Currently only compare to unsigned char is implemented,
3643 * src/pic16/gen.c: added fReturnIdx array,
3644 * (struct resolvedIfx) is moved to gen.h and made public,
3645 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3646 * (aopForSym): added an optimization to directly store in stack of
3647 the operand of a SEND iCode,
3648 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3649 but as registers instead (AOP_REG) using the fReturnIdx array,
3650 * (pic16_freeAsmop): remove the freed register from the
3651 _G.sregsAlloc field,
3652 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3653 a compare of 'WREG',
3654 * (pic16_popGetTempRegCond): changed function prototype, now
3655 function takes also a bitVector argument v which holds the current
3656 set of registers that are allocated for stack access by aopForSym,
3657 registers allocated in aopForSym for accessing stack symbols are not
3658 any more part of the functions usedRegs field,
3659 * (genCall): some times aopOp is called for a stack variable to be
3660 send, aopForSym might perform the push, if this is true make sure
3661 that genCall doesn't push the variable twice by testing _G.resDirect,
3662 * (genFunction): changed testing for unspecified interrupt number
3663 from 256 to INTNO_UNSPEC,
3664 * modified selection scheme of frame pointer generation. Previously
3665 if function did use local registers a frame pointer was generated,
3666 now a frame pointer is generated only if function has arguments
3667 (that need PLUSW2 register access), or has stack arguments, or the
3668 compiler is not instructed to omit the frame pointer,
3669 * (genEndFunction): before restoring local registers that were saved
3670 in the function preamble, also restore the registers that *might*
3671 have been allocated for stack access,
3672 * (genRet): removed some old comments,
3673 * (genCmp, the active (RN's) version): added a call to the
3674 pic16_genCmp_special function to perform the compare with a more
3675 robust and optimized way,
3676 * (genInline): a feature has been added in inline code generation,
3677 which allows a wildcard variable substitution when writing inline
3678 assembly. Code is incomplete and experimental therefore undocumented,
3679 * (genCast): changed order of aopOp for result and right to allow
3680 aopForSym to directly load the result if possible,
3681 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3682 perform an optimized compare on some selected special occasions,
3683 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3684 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3685 generate an IVT any more,
3686 * src/pic16/main.c (pic16_optionsTable): added command line option
3688 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3689 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3691 * src/pic16/NOTES: Raphael Neider added in list of active developers
3692 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3693 jumptable_end to prevent bug #,
3694 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3695 inCond and outCond fields,
3696 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3697 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3698 turn off register spilling,
3699 * (packRegsForOneUse): synced with other ports' versions although it
3700 is not used currently,
3701 * (pic16_packRegisters): added an optimization while reading
3702 structure bitfields, some registers may be saved (malloc code is
3703 decreased by 80 bytes)
3705 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3707 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3708 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3709 this can be optimized more?
3711 2005-03-10 Raphael Neider <rneider AT web.de>
3713 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3714 genNearPointerGet): (hopefully) fixed access to bitfields via
3715 pointers (p->bitN = x; and x = p->bitN; failed)
3717 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3760 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3761 to keep the correct label reference count when adding/removing references
3762 to labels. A peephole file using this is appended to patch #1144962.

3894 * src/pic16/main.c (_process_pragma): fixed another malloc bug
3895 (sizeof(sectNames) changed to sizeof(sectName))
3896 Both patches fix segfaults under MinGW.

3902 * src/pic16/gen.c (pic16_aopOp,pic16_popGet): added handling
3903 of (byte sized) temporaries (assign them to WREG for now)
3904 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3905 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3906 this might fix SIGSEGVs on MinGW...
3907 * src/SDCCopt.c (killDeadCode): restored original behaviour
3908 (volatile operands might get thrown away though)

4336 comparisons, and supports quoted literals
4337 * src/mcs51/peeph.def: restored rule 177.d with an extra condition
4339 2004-12-02 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

4347 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
4349 Adding support for replacing ljmps with sjmps in jumptables
4350 generated for switch statements. For now you need to set the
4351 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4352 Now 4 algorithms for mcs51 jumptable generation are used:
4353 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4354 addresses loaded pc-relative for up to 112 cases and stack-pushing
4355 target addresses loaded with offset from dptr for up to 256 cases.
4357 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
4358 * src/mcs51/main.c: adapted constants for switch table generation
4359 * src/mcs51/peeph.def: added 260.x for replacing ljmp with sjmp

4381 Large cummulative patch for pic16 port.
4382 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4383 to call when a stack overflow occurs,
4384 * (malloc.h): added CVS Id tag,
4385 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4387 * added libc directory. The current version of LibC contains string
4388 functions, ctype functions and macros and some functions of the
4389 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4390 be extensively tested in the future. Standard disclaimer here.
4391 Library is not automatically build yet. But one can build it by
4392 invoking 'make' inside the libc directory.
4393 * added ADC library under libio. Preliminary version yet.
4395 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
4396 * src/pic16/gen.c (aopForRemat): asmop size is filled by
4397 aopForRemat() now and not by pic16_aopOp(),
4398 * (pic16_popGetTempReg): removed warning messgae when allocating
4399 temporary registers, its a buggy feature and will be removed,
4400 * (pic16_popGet): set register instance field in AOP_CRY,
4401 * (pic16_outBitC): fixed for results in size greater than 1,
4402 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4403 * (pic16_storeForReturn): optimized return of 0,
4404 * (genCmp): experimental code for new genCmp which uses PIC18's
4405 special compare&skip instructions. Initial tests fail some times
4406 with variables grater than 1 byte in size, so new code is disabled,
4407 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4409 * (genCast): began a fix to optimize the casting of a bit to another
4410 bit, now assigning a bitfield to another bitfield will fail, sorry,
4411 * src/pic16/main.c: disabled the use of lr-support feature,
4412 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4413 * added some function prototypes, added function _debugf prototype,
4414 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
4415 bits with offset (case PO_GPR_BIT),
4416 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4418 * (isBankInstruction): modified to return 0 for no banking instruction,
4419 and 1 for banking instruction,
4420 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4421 caused stop processing pCodes after a inline assembly block,
4422 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4423 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4424 registers when it shouldn't,
4425 * src/pic16/ralloc.c (allocReg): add preliminary support for
4426 supporting a limited set of temporary registers,
4428 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4430 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4431 genDataPointerSet): ensure assignments always copy in MSB to LSB
4433 (loadRegFromAop): recognize CLRH optimization,
4434 (genFunction): optimize RECEIVE iCodes in reentrant functions
4436 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4438 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4439 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

4448 * device/lib/_gptrgetc.c (_gptrgetc),
4449 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
4450 instead of sjmp to ret
4451 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
4452 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4454 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7436 loaded with the linker search paths (-L arguments) and the libraries
7437 to be linked with the current source (-l arguments). Changes
7438 currently will affect only the pic16 port.
7439 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7440 include path the port specific paths and port specific libraries,
7441 * gplink command now contains the $3 argument,
7442 * src/pic16/device.h,
7443 * src/pic16/device.c,: structure PIC_device is made public and
7444 renamed to PIC16_device, the same for variable Pics which is renamed
7445 to Pics16. Updated all references to them.
7446 * src/pic16/glue.c (pic16glue): corrected bug with code
7447 initialization which bypassed the variable initializations block.
7449 * device/lib/pic16/Makefile.rules: removed --penable-stack from
7450 COMPILE_FLAGS and added the --nostdinc option
7452 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7454 * device/include/mc68hc908jb8.h: Register defs for another member
7455 of the hc08 family. Contributed by Bjorn Bringert - thanks!
7457 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7459 Documenting changes from previous commits.
7460 * configure.in (version 1.56),
7461 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7462 when generating output files to configure the pic16 library,
7463 but now I've commented it out, since gputils aren't installed in the
7464 SF compile farm, so library won't compile
7466 * device/lib/Makefile.in (version 1.56): initially I've added in
7467 target 'all' the prerequestive 'model-pic16' so it compiled the
7468 pic16 library, but now I've commented it out for the same reasons
7470 * added targets 'model-pic16' and 'objects-pic16' to compile the
7472 * added target 'port-specific-objects-pic16' to handle the
7473 generated libraries and copy them into the build/ directory
7474 * added target 'clean-intermediate-pic16' to clean intermediate
7475 files into pic16 directory
7476 * in target 'installdirs' added line to create directory pic16 in
7477 the installation path
7479 * device/include/Makefile.in (version 1.11): in target 'install'
7480 added lines to copy all header files to installation path,
7481 * in target 'installdirs' added line create directory for pic16
7482 headers in the installation path

7497 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7498 option so that it actually works. Made it specific to the z80, since
7499 the gbz80 doesn't have these kinds of I/O ports.
7501 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7503 * device/include/z180.h,

7525 Mainly changes to support compilation of the device libraries
7526 * src/pic16/device.c: stack is allocated via symbol and not
7527 via literal number. The symbol is placed in the corresponding
7528 position of the data ram
7529 * (pic16_dump_section): relocatable and absolute uninitialized
7530 data are now emitted in sorted order to reduce section naming,
7531 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7532 weren't marked as being in the access bank,
7534 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7536 Added portion of GNU PIC Library under the directory
7537 device/include/pic16 and device/lib/pic16. These files
7538 contain the declarations of SFRs for the PIC18Fxx2 devices.
7539 The directory is initialized via configure from toplevel.
7541 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7543 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
7544 the spilllocations to be compared correctly
7546 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7548 * src/SDCCast.c (decorateType): fixed bug introduced today
7550 2004-01-12 Borut Razem <borut.razem AT siol.net>

7568 * doc/sdccman.lyx: Moved and added some sections, small changes
7569 all over. Telling LaTeX to be less strict with word spacing
7570 to better keep the right margin. Changed some notes about
7571 maintainance of the ports in section 3.2.1 - is it OK like this?
7573 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7610 UPPER for immediate operands,
7611 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7613 * src/pic16/peeph.def: all peepholes with movff are commented out,
7614 because there is a problem in the pcode peep optimizer,
7615 * src/pic16/ralloc.c: the register allocator can now reuse local

7617 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7619 Added file src/pic16/NOTES with information about program writing on
7620 the current port version.

7652 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7655 * src/z80/main.c: added missed needLinkerScript flags (more than
7656 one port structure defined in these file)
7657 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

7673 needLinkerScript flag
7675 * src/pic16/gen.c (genAddrOf): fixed bug #863624
7676 * src/pic/glue.c: added variable udata_section_name to
7677 override default uninitialized data segment definition for
7678 devices only with SHAREBANK memory (reported from Erik Epetrich)
7679 * (pic14emitOverlay): modified to emit a commented overlay segment
7680 directive when no overlay data exist
7681 * (picglue): modified to emit uninitialized data segment
7682 according to udata_section_name

7688 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7689 object file from '.rel' to '.o' in port->linker structure,
7690 changed size of fptr from 2 to 3 in port structure
7692 2004-01-07 Borut Razem <borut.razem AT siol.net>
7694 * support/scripts/sdcc.nsi: update PATH
7695 * support/scripts/sdcc.ico: craeted

7708 include information about variables allocated to the overlay
7711 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7713 * as/mcs51/lkmain.c: Help about -Y option

7725 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7727 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7728 (default behaviour).
7730 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7732 A python script to validate compiler diagnostic messages. It can be
7733 used to verify that sdcc complains about bad c source code and
7734 gives a good location of the error.
7735 * support/valdiag/Makefile,
7736 * support/valdiag/valdiag.py,
7737 * support/valdiag/tests/*
7739 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7754 Bug reported from Jesus Calvino-Fraga
7756 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7758 * sdcc.spec: updated
7759 * device/include/Makefile.in: don't install CVS directories
7760 * device/lib/Makefile.in: added removal of CVS directories after install
7761 * doc/Makefile: fixed install, added local_icons
7762 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7763 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7764 * src/ds390/gen.c (genRightShift): fixed bug #870788
7765 * src/SDCCast.c (decorateType): fixed bug #870781
7767 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7769 PIC16 port related changes:
7770 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7771 added variable stackPos,
7773 * gen.c: genCall, assignResultValue: added support for
7774 pushing/retrieving function parameters to/from stack,
7775 genFunction,genEndFunction: setup stack frame for the
7777 genAddrOf: will be changed according to bug 863624
7779 * added files genutils.c and genutils.h which contain gen*
7780 debugged and optimised functions extracted from gen.c
7782 * glue.c: added variable 'externs' which holds extern symbols,
7783 pic16emitRegularMap: is modified to properly handle relocatable
7784 symbols under the new scheme,
7785 pic16createInterruptVect: is modified
7786 pic16printPublics: is modified to emit 'global' assembler directives,
7787 added pic16_printExterns to print extern symbols,
7788 pic16glue: initializes stack/frame pointer in the beginning of
7789 the assembly output. Temporary hack, will be corrected later,
7790 because gplink yet does not support stack and SDCC does not
7791 yet support a type of crt0.o object to create the final binary.
7793 * Removed many lines that contain 8051 legacy code.
7794 * The code is finally placed under a 'code' directive.
7795 * Added port specific options.
7797 * _process_pragma: simplified since now we do not need *special*
7798 include file to define SFR registers. But a separate header
7799 will be needed. This will be developed later.
7800 * _pic16_parseOptions: added, parses port specific options:
7801 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7802 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7803 --preplace-udata-with=
7805 * _pic16_setDefaultOptions: modified to initialize section names,
7806 but hack is temporarly out of order since it needs improvement.
7807 * _pic16_genAssemblerPreamble: configuration words are emitted by
7808 their address instead of their name. This part is incomplete and
7809 supports only the 18Fxx2 devices. Other devices will emit an error
7810 during assembly since they do not contain the same set of config
7812 * _pic16_genIVT: is modified,
7814 * pcode.c: added definitions for some hardware registers that are needed
7816 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7817 All PCI entries are updated. Now LFSR is supported.
7818 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7819 * added pic16_newpCodeOpLit2 to support instructions with
7820 two literal arguments
7821 * pic16_pCode2str: corrected code that emits assembler instructions
7822 with two literal operands and those that have an access bit modifier
7823 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7824 this fixes a bug which caused some labels to be lost, when an
7825 assembler directive was added, i.e. banksel,
7826 * pic16_FixRegisterBanking: improved logic that causes the insertion
7828 * InlineFunction: functions that are called once, are not any more
7829 inlined. This can be a port option in the future,
7831 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7833 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7834 hold the corresponding uninitialized symbols,
7835 * pic16_allocProcessorRegister: registers have explicit marked the
7837 * pic16_allocInternalRegister: registers are explicit marked as
7839 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7840 processing list, so bit registers were lost,
7843 * ralloc.h: added field 'accessBank' and original symbol operand
7844 in register definition,
7845 * removed the field isMapped from register definition,
7847 ** Several functions have been removed from various sources:
7848 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7849 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7850 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7851 pic16_assignRelocatableRegisters
7853 ** others have been introduced:
7854 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7855 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7857 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7859 * support/scripts/inc2h.pl: changed definition of BIT_AT
7860 to emit 'sbit at' instead of 'bit at'. This was a request.
7862 PIC16 port related preliminary changes:
7863 * gen.c: prefixed function popRegFromString with
7864 pic16_ and all references to it corrected
7865 * pcode.c: all pic16_pc_* hardware registers prefixed
7866 with underscore (_),
7867 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7868 * ralloc.c: newReg(): when register is REG_SFR then
7869 set address to rIdx,
7870 pic16_allocProcessorRegister(): marks register wasUsed=0
7871 pic16_writeUsedRegs(): added a call to assign processor
7872 registers via pic16_assignFixedRegisters
7874 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7876 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7877 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7878 variables in unused register banks. Also the SSEG is placed
7879 wherever there is enough space for it, and IDATA can be anywhere
7880 in internal RAM. For now compile using -Wl-Y[stack_size].
7881 The mem file is different for this option as well, since it
7882 makes no sense of talking about DSEG lenght.
7884 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7886 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7887 in certain cases, e.g. when ROM assignment, patch provided
7888 from Albert den Haan.
7890 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8933 A few small changes that speed up the peephole optimizer.
8937 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8939 Try to make the peephole optimizer smarter by maintaining
8940 an association between the assembly source code and the
8941 iCodes that originated them. Put this information to use
8942 with a new peephole rule condition "notVolatile" so that
8943 the rules can be aggressive yet still safe.
8948 * src/mcs51/peeph.def
8950 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8954 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8955 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8956 if the left or right operand symbols have the accuse flag set.
8958 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8960 Changed the type of the result of the ! (NOT) operator to char;
8961 previously it returned the same type as the source. This allows
8962 us to eliminate all the genFloatNot functions (all of its target
8963 implementations were very buggy) since !float can use the same
8966 * src/SDCCicode.c (ast2iCode): ! returns char
8967 * src/mcs51/gen.c (genNot, genNotFloat),
8968 * src/ds390/gen.c (genNot, genNotFloat),
8969 * src/z80/gen.c (genNot, genNotFloat),

8975 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8976 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8977 during interrupts. Ensure WSAVE is located at a shared bank address.
8978 2. Fixed page selection in some places
8979 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8980 the registers name strings.
8981 4. Fixed "signed / unsigned compare" compiler warnings.
8982 5. The PIC port manages its own allocation of the general purpose
8983 registers, but makes no attempt to reuse them. As a result when
8984 compiling it soon runs out of general purpose registers. Some
8985 additional code was added to the files pcode.c and device.c to walk
8986 through the function call tree and rename the registers so that they
8996 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8997 genPlus() & genMinus() when the result is the same as left or right

9003 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9005 Made bitfield a distinct type from bit so that bitfields
9006 convert as per ANSI C and bits retain their traditional
9007 boolean style behaviour. Implemented bitfield support in
9015 * src/ds390/gen.c: bit v bitfield split
9016 * src/z80/gen.c: New support for bitfields
9017 * support/regression/tests/bitfields.c: reenabled z80,
9020 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9022 Rules 246.x, 247.x relate to bitfields, the others speed up
9023 access to xdata mapped I/O devices.
9025 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9027 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9029 Cleaned up genPackBits and genUnpackBits and added two helper
9030 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9031 for literal assignments in genPackBits (thanks to Frieder for
9037 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9039 Fixed bug #748310 (pointer to function type mishandled when the
9040 function name is omitted). Also fixed a SIGSEGV when a function
9041 attribute (reentrant, etc) is used on a non-function or on a
9042 function but misplaced before the parameter list.
9044 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9046 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9069 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9071 Made the constant following the "interrupt" keyword optional. If
9072 omitted, the function will not automatically be given an entry
9073 in the interrupt vector table (similar to #pragma NOIV, but
9074 less syntacticly kludgy). The interrupt number is also now
9075 range checked. Also fixed a bug in the high order bit example

9516 condition and ignore commands.
9518 2003-05-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9520 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
9521 is in parts still quite out of date, I did changes as far as I felt makes sense
9522 for a non-native english speaker.
9523 Please feel free to add to the manual or to correct my changes.
9524 * doc/Makefile: undid touching the date of intermediate tex files.
9526 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9541 2003-05-25 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9543 * as/mcs51/lkaomf51.c: Address space 'z' was missing.
9544 * src/avr/avr.dsp, src/ds390/ds390.dsp, src/mcs51/mcs51.dsp,
9545 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
9546 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used
9549 2003-05-25 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9551 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9552 the regression tests I'm not brave enough to enable 245.b, 245.c
9553 * doc/sdccman.lyx: added latex preamble for hyperref package.
9554 Using pdflatex this will give you a hyperlinked pdf file with
9555 bookmarks. (prepend '%' before /usepackage if this breaks something)
9557 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9571 Applied patch from bug 737905 (renamed yylineo to mylineno):
9578 * src/pic16/pcode.c: Cleaned warnings
9579 * src/pic16/pcodeflow.c: Cleaned warnings

9593 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9595 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9596 it can be defined with CFLAGS when running configure
9597 * src/SDCCmain.c: fixed compiling + linking with object files
9599 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9601 * configure.in: configure for pic16 port,
9602 added --disable-pic16-port
9603 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9604 * src/SDCCmain.c: linkOptions is changed to set *,
9605 added if/endif conditional macros to remove options help
9606 messages from optionsTable when a port is not configured, added
9607 support for the PIc16 port in the ports table, when executing
9608 the compiler with no port specified on command line, a default
9609 port is selected with the new macro DEFAULT_PORT which is
9610 defined in port.h, in setDefaultOptions() linkOptions is removed
9611 from initialization assignment, since now it is a set,
9612 parseCmdLine uses setParseWithComma for linkOptions, in
9613 linkEdit() linkOptions are accessed with new function indexSet()
9614 which returns the i'th item of a set variable. See SDCCset.c, in
9615 linkEdit() when calling buildCmdLine(), added linkOptions as
9616 last argument. Now users can pass arguments to gplink via the
9617 -Wl option, main() uses pic16glue() to glue up pic16 programs
9618 * src/SDCCpeeph.c: various changes to support pic16
9619 * src/SDCCset.c: added function void *indexSet(set *, int) to
9620 return the i'th item of the set

9623 * src/clean.mk: added pic16 in CLEANALLPORTS variable
9624 * src/port.h: added TARGET_ID_PIC16,TARGET_IS_PIC16 macro,
9625 added macro DEFAULT_PORT
9626 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
9627 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
9629 * src/pic16/glue.c: commented out some error producing lines
9630 * src/pic16/main.c: __config directives are commented out to stop
9631 gpasm complaining and test the linkage with gplink, _linkCmd and
9632 _asmCmd changed to be more gplink and gpasm friendly
9633 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9634 produced an error when parsed, peep rule 12 is added to utilize
9635 movff, but it is commented out since the pCode does not support
9636 yet a command with 2 address arguments
9638 2003-05-18 <johan AT balder>
9640 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9641 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9660 on entry now. Add tbreak. Other enhancements and fixes for use
9663 2003-05-12 Borut Razem <borut.razem AT siol.net>
9665 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9667 2003-05-11 Borut Razem <borut.razem AT siol.net>
9669 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9670 the path of bin directory, so that PATH is the only env. variable, which has to be set
9671 in case of standard installation.
9672 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10701 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10703 * in \sdcc\as\mcs51\ changed these files in order to create an
10704 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10705 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10706 following files to include the previous two files: aslink.dsp,
10707 Makefile.aslink, Makefile.bcc, and Makefile.in.
10709 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10710 .adb instead of .cdb
10712 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10714 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10715 value from option --iram-size.
10717 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10719 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10722 2002-09-18 <wiml AT hhhh.org>
10724 * SDCClrange.h: exposed setFromRange() and setToRange()
10725 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10726 packRegsForAccUse() (bug 542397)
10727 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10728 multiple times and emitting the fetch operations more than once
10729 added aopGetUsesAcc() function to allow binary operators to
10730 fetch their operands in the correct order; made genMinus() emit
10731 compact code for X = LITERAL - Y
10733 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10734 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10735 sprintf() in line 1267.
10737 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10738 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10741 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10742 Changes to aslink (All the changes are marked with 'JCF'):
10744 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10747 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10748 area BSEG. Also moves, if possible, the DATA area down into the internal
10749 ram so more space is available.
10751 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10754 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10755 not bytes. Function summary() which creates a memory usage summary
10756 file with extension .mem. Reports of overlaping stack and small stack
10757 size. If the space for the stack is less than 16 bytes aslink trows a
10760 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10761 the 8051. Option 'y' for memory summary output file.
10763 Changes to sdcc (All the changes are marked with 'JCF'):
10765 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10767 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10768 overlaying area for it (uses RegBankUsed[4]).
10770 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10771 bank zero as used by default. By default aslink locates the stack
10772 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10773 the creation of the .mem file. Delegates the allocation of data area
10774 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10775 the begining of the stack area to aslink.
10777 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10778 glue() in SDCCglue.c creates an area for it.
10780 2002-09-03 Borut Razem <borut.razem AT siol.net>
10781 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10782 sdcc/src/pic/glue.c:
10783 introduced atexit() handler for teporay files removal in case of
10784 errors, assertions, ...
10786 2002-08-29 Borut Razem <borut.razem AT siol.net>
10787 * sdcc/support/cpp2/auto-host_vc_in.h:
10788 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10789 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10790 Maybe there is a similar problem with BORLANDC? It should be checked!
10792 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10793 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10794 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10795 was not executed, and the compiler (cl) launched a warning:
10796 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10798 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10799 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10801 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

10805 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10806 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10807 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10808 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10809 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10810 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10811 - added Release configuration in VS projects
10812 - review of compiler an linker options
10813 - VC .exe files are generated in bin_vc directory, not to interfere
10814 with binaries generated from other projects (cygwin, mingw, bcc ...)
10816 * sdcc/src/yacc.dsp: added
10818 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10819 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10820 and insert the version number definitions from .version
10822 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10824 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

10834 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10836 2002-08-10 Borut Razem <borut.razem AT siol.net>
10837 * src/SDCCmain.c (main):
10838 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10839 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10840 The consequence was that some temporary files were not removed.
10843 unification of code in functions tempfilename() and tempfile():
10844 function tempnam() is defined in Visual Studio 6.0 and .NET
10846 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10848 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10849 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

10853 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10854 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10855 changed project type to Generic Project so that can be correcly converted to VS.NET project
10857 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10859 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

10863 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10864 added return 0 statements after assert() to make compiler happy
10866 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10867 added newline in the def file to keep MSC compiler satisfied
10869 * sdcc/src/z80/gen.c:
10870 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10871 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10872 - solved MSC error in function aopDump()
10874 * sdcc_vc.h: define PREFIX as "\\sdcc"
10876 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11049 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11051 * sdcc/src/SDCCloop.c:
11052 Previous fix was not good. basic blocks that have "break" or "return" are
11053 not really partof a loop , but live ranges used in these blocks should
11054 be live thru the entire loop, so set partOfLoop but don't add them to
