1701 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1703 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1704 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1706 One basic decision: e.g. src/clean.mk includes further files. In order
1707 to make this work there are two solutions:
1708 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1709 run configure on them. This way they can use
1710 'include $(srcdir)/port-clean.mk'
1711 - always include clean.mk by the Makefile at the same level. To avoid
1712 that `make clean` tries to include and build Makefile.dep the
1713 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1714 implemented, because now even `make uninstall` doesn't create
1715 Makefile.in. clean.mk could be eliminated by pasting it in
1718 * debugger/mcs51/Makefile.in: build own objects from library sources
1719 (SLIB, SDCC) in current directory
1721 * configure, configure.in: renamed --disable-device-lib-build in
1722 --disable-device-lib; added --enable-doc, the required tools are
1723 searched by configure; added result message; the toolchain for the
1724 belonging ports are now only built, if the port is enabled.
1726 * support/regression/*: all output is written in directory gen, because
1727 the fwk and ports directories don't livet in the build tree using vpath
1729 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1730 --disable-device-lib, added --enable-doc, added section VPATH
1732 * sim/ucsim/configure.in,
1733 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1734 z80 are enabled by default
1736 2006-04-24 Raphael Neider <rneider AT web.de>
1738 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1739 to config word, "pic14_"-prefixed some extern functions
1740 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1741 config word has been found
1742 * src/pic/device.h: added prototypes
1743 * src/pic/pcode.c: added "pic14_"-prefix where needed
1744 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1746 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
1748 (pic14emitRegularMap): ignore config words,
1749 (pic14createInterruptVect): moved generating __config directives away
1750 (picglue): have __config directives emitted
1752 2006-04-24 Borut Razem <borut.razem AT siol.net>
1754 * doc/Makefile: sync with nightly build makefile
1756 2006-04-24 Raphael Neider <rneider AT web.de>
1758 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
1759 registers that have not been assigned proper liveranges,
1760 fixes #1469504 and #1474602,
1761 (pCodeRegOptimizeRegUsage): fixed typo in comment
1763 2006-04-24 Borut Razem <borut.razem AT siol.net>
1765 * device/examples/main8051.c: deleted - it was removed from CVS
1766 24.mar.2000 and after that modified 18.feb.2001, so it reappered
1767 after the transition to Subversion
1768 * src/SDCCalloc.h: deleted - it was removed from CVS
1769 3.feb.2001 and after that modified 18.feb.2001, so it reappered
1770 after the transition to Subversion

2029 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2031 * src/.version: increased version number to 2.5.5
2032 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2033 linking is done manually in pic16 port's _linkEdit,
2034 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2035 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

2037 allocate asmop as AOP_ACC,
2038 (aopForRemat): added parameter 'bool result' in function declaration,
2039 (pic16_aopGet): return AOP_ACC when accessing WREG,

2052 call to allocReg, not by manually allocating a new one,
2053 (pic16_assignRegisters): now before going through the register
2054 allocating functions mark all registers as free. This eliminates some
2055 side effects resulting from peephole parser done earlier in the backbone

2117 the number of the local variables used by the specified function, added
2118 'xinst' for initial support for Extended Instruction Support,
2119 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2120 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2121 port->fun_prefix anymore (may change later),
2122 (genFunction, genEndFunction): do not store/restore local registers for
2123 _main (this should take care the --main-return command line option in
2125 (genOr): removed some legacy pic-port instructions,
2126 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2127 performing operations with SFR's causes data to be written more than
2128 once to each SFR. Perhaps SFRs should be handled in special cases...
2129 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2131 * src/pic16/main.c (_process_pragma): stack bound checking did not take

2137 (commented out for reference), didn't account for some registers which
2138 were left marked 'not free' after a pointer operation. The change
2139 reduces register usage a lot in some cases

4415 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4416 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4417 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4418 always available in leading double underscore form. The C99 support is
4419 mostly missing, but it's a start.
4420 * support/regression/tests/bug-227710.c: fixed nonconforming use of

4499 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4501 * device/lib/printf_large.c: removed inline assembly for portability and
4502 readability. Use printf_fast if speed or size are more important.
4503 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4504 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4506 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4508 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4509 prevent compiler warning
4511 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4513 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4514 moved to level 0 and declared as static. Also they are explicit
4515 placed in access bank. This was necessery because some times they
4516 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4517 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4518 optimizations. Currently only compare to unsigned char is implemented,
4519 * src/pic16/gen.c: added fReturnIdx array,
4520 * (struct resolvedIfx) is moved to gen.h and made public,
4521 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4522 * (aopForSym): added an optimization to directly store in stack of
4523 the operand of a SEND iCode,
4524 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4525 but as registers instead (AOP_REG) using the fReturnIdx array,
4526 * (pic16_freeAsmop): remove the freed register from the
4527 _G.sregsAlloc field,
4528 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4529 a compare of 'WREG',
4530 * (pic16_popGetTempRegCond): changed function prototype, now
4531 function takes also a bitVector argument v which holds the current
4532 set of registers that are allocated for stack access by aopForSym,
4533 registers allocated in aopForSym for accessing stack symbols are not
4534 any more part of the functions usedRegs field,
4535 * (genCall): some times aopOp is called for a stack variable to be
4536 send, aopForSym might perform the push, if this is true make sure
4537 that genCall doesn't push the variable twice by testing _G.resDirect,
4538 * (genFunction): changed testing for unspecified interrupt number
4539 from 256 to INTNO_UNSPEC,
4540 * modified selection scheme of frame pointer generation. Previously
4541 if function did use local registers a frame pointer was generated,
4542 now a frame pointer is generated only if function has arguments
4543 (that need PLUSW2 register access), or has stack arguments, or the
4544 compiler is not instructed to omit the frame pointer,
4545 * (genEndFunction): before restoring local registers that were saved
4546 in the function preamble, also restore the registers that *might*
4547 have been allocated for stack access,
4548 * (genRet): removed some old comments,
4549 * (genCmp, the active (RN's) version): added a call to the
4550 pic16_genCmp_special function to perform the compare with a more
4551 robust and optimized way,
4552 * (genInline): a feature has been added in inline code generation,
4553 which allows a wildcard variable substitution when writing inline
4554 assembly. Code is incomplete and experimental therefore undocumented,
4555 * (genCast): changed order of aopOp for result and right to allow
4556 aopForSym to directly load the result if possible,
4557 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4558 perform an optimized compare on some selected special occasions,
4559 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4560 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4561 generate an IVT any more,
4562 * src/pic16/main.c (pic16_optionsTable): added command line option
4564 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4565 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4567 * src/pic16/NOTES: Raphael Neider added in list of active developers
4568 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4569 jumptable_end to prevent bug #,
4570 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4571 inCond and outCond fields,
4572 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4573 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4574 turn off register spilling,
4575 * (packRegsForOneUse): synced with other ports' versions although it
4576 is not used currently,
4577 * (pic16_packRegisters): added an optimization while reading
4578 structure bitfields, some registers may be saved (malloc code is
4579 decreased by 80 bytes)
4581 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4583 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4584 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4585 this can be optimized more?
4587 2005-03-10 Raphael Neider <rneider AT web.de>
4589 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4590 genNearPointerGet): (hopefully) fixed access to bitfields via
4591 pointers (p->bitN = x; and x = p->bitN; failed)

5225 Adding support for replacing ljmps with sjmps in jumptables
5226 generated for switch statements. For now you need to set the
5227 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5228 Now 4 algorithms for mcs51 jumptable generation are used:
5229 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5230 addresses loaded pc-relative for up to 112 cases and stack-pushing
5231 target addresses loaded with offset from dptr for up to 256 cases.
5233 * src/SDCCpeeph.c: added peephole conditional labelJTInRange
5234 * src/mcs51/main.c: adapted constants for switch table generation

5258 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5259 to call when a stack overflow occurs,
5260 * (malloc.h): added CVS Id tag,
5261 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5263 * added libc directory. The current version of LibC contains string
5264 functions, ctype functions and macros and some functions of the
5265 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5266 be extensively tested in the future. Standard disclaimer here.
5267 Library is not automatically build yet. But one can build it by
5268 invoking 'make' inside the libc directory.
5269 * added ADC library under libio. Preliminary version yet.
5271 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

5278 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5279 * (pic16_storeForReturn): optimized return of 0,
5280 * (genCmp): experimental code for new genCmp which uses PIC18's
5281 special compare&skip instructions. Initial tests fail some times
5282 with variables grater than 1 byte in size, so new code is disabled,
5283 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5285 * (genCast): began a fix to optimize the casting of a bit to another
5286 bit, now assigning a bitfield to another bitfield will fail, sorry,
5287 * src/pic16/main.c: disabled the use of lr-support feature,
5288 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
5289 * added some function prototypes, added function _debugf prototype,

5291 bits with offset (case PO_GPR_BIT),
5292 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5294 * (isBankInstruction): modified to return 0 for no banking instruction,
5295 and 1 for banking instruction,
5296 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5297 caused stop processing pCodes after a inline assembly block,
5298 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5299 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5300 registers when it shouldn't,
5301 * src/pic16/ralloc.c (allocReg): add preliminary support for
5302 supporting a limited set of temporary registers,
5304 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5306 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5307 genDataPointerSet): ensure assignments always copy in MSB to LSB
5309 (loadRegFromAop): recognize CLRH optimization,
5310 (genFunction): optimize RECEIVE iCodes in reentrant functions
5312 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5314 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8309 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8311 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8312 loaded with the linker search paths (-L arguments) and the libraries
8313 to be linked with the current source (-l arguments). Changes
8314 currently will affect only the pic16 port.
8315 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8316 include path the port specific paths and port specific libraries,
8317 * gplink command now contains the $3 argument,
8318 * src/pic16/device.h,
8319 * src/pic16/device.c,: structure PIC_device is made public and
8320 renamed to PIC16_device, the same for variable Pics which is renamed
8321 to Pics16. Updated all references to them.

8333 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
8335 Documenting changes from previous commits.
8336 * configure.in (version 1.56),
8337 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8338 when generating output files to configure the pic16 library,
8339 but now I've commented it out, since gputils aren't installed in the
8340 SF compile farm, so library won't compile
8342 * device/lib/Makefile.in (version 1.56): initially I've added in
8343 target 'all' the prerequestive 'model-pic16' so it compiled the
8344 pic16 library, but now I've commented it out for the same reasons
8346 * added targets 'model-pic16' and 'objects-pic16' to compile the
8348 * added target 'port-specific-objects-pic16' to handle the
8349 generated libraries and copy them into the build/ directory
8350 * added target 'clean-intermediate-pic16' to clean intermediate
8351 files into pic16 directory
8352 * in target 'installdirs' added line to create directory pic16 in
8353 the installation path
8355 * device/include/Makefile.in (version 1.11): in target 'install'
8356 added lines to copy all header files to installation path,
8357 * in target 'installdirs' added line create directory for pic16
8358 headers in the installation path

8373 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8374 option so that it actually works. Made it specific to the z80, since
8375 the gbz80 doesn't have these kinds of I/O ports.
8377 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8379 * device/include/z180.h,

8392 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8394 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
8395 changed interrupt vector table generation to only emit declared vectors.
8396 * device/include/Makefile.in: added missing backslash
8397 * device/lib/pic16/Makefile.rules: add $(MODELFLAGS) to $(CFLAGS)
8399 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8401 Mainly changes to support compilation of the device libraries
8402 * src/pic16/device.c: stack is allocated via symbol and not
8403 via literal number. The symbol is placed in the corresponding
8404 position of the data ram
8405 * (pic16_dump_section): relocatable and absolute uninitialized
8406 data are now emitted in sorted order to reduce section naming,
8407 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8408 weren't marked as being in the access bank,
8410 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8412 Added portion of GNU PIC Library under the directory
8413 device/include/pic16 and device/lib/pic16. These files
8414 contain the declarations of SFRs for the PIC18Fxx2 devices.
8415 The directory is initialized via configure from toplevel.
8417 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8419 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
8420 the spilllocations to be compared correctly
8422 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8424 * src/SDCCast.c (decorateType): fixed bug introduced today
8426 2004-01-12 Borut Razem <borut.razem AT siol.net>
8428 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,

8431 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8433 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
8434 in simpler and even better code
8436 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
8438 * src/SDCCicode.c (operandOperation): fixed bug #874819

8444 * doc/sdccman.lyx: Moved and added some sections, small changes
8445 all over. Telling LaTeX to be less strict with word spacing
8446 to better keep the right margin. Changed some notes about
8447 maintainance of the ports in section 3.2.1 - is it OK like this?
8449 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8486 UPPER for immediate operands,
8487 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8489 * src/pic16/peeph.def: all peepholes with movff are commented out,
8490 because there is a problem in the pcode peep optimizer,
8491 * src/pic16/ralloc.c: the register allocator can now reuse local
8492 function symbols for another function. This saves register usage.
8493 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8495 Added file src/pic16/NOTES with information about program writing on
8496 the current port version.

8525 gen51Code): more efficient parameter receive for --model-large
8528 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8531 * src/z80/main.c: added missed needLinkerScript flags (more than
8532 one port structure defined in these file)
8533 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

8549 needLinkerScript flag
8551 * src/pic16/gen.c (genAddrOf): fixed bug #863624
8552 * src/pic/glue.c: added variable udata_section_name to
8553 override default uninitialized data segment definition for
8554 devices only with SHAREBANK memory (reported from Erik Epetrich)

8556 directive when no overlay data exist
8557 * (picglue): modified to emit uninitialized data segment
8558 according to udata_section_name

8564 * src/pic16/main.c: added $l in _asmCmd, changed extension for
8565 object file from '.rel' to '.o' in port->linker structure,
8566 changed size of fptr from 2 to 3 in port structure
8568 2004-01-07 Borut Razem <borut.razem AT siol.net>
8570 * support/scripts/sdcc.nsi: update PATH
8571 * support/scripts/sdcc.ico: craeted

8584 include information about variables allocated to the overlay
8587 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8589 * as/mcs51/lkmain.c: Help about -Y option

8601 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8603 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8604 (default behaviour).
8606 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8608 A python script to validate compiler diagnostic messages. It can be
8609 used to verify that sdcc complains about bad c source code and
8610 gives a good location of the error.
8611 * support/valdiag/Makefile,
8612 * support/valdiag/valdiag.py,
8613 * support/valdiag/tests/*
8615 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8628 * src/common.h: added ifndef/define/endif macros
8629 around the header file.
8630 Bug reported from Jesus Calvino-Fraga
8632 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8634 * sdcc.spec: updated
8635 * device/include/Makefile.in: don't install CVS directories
8636 * device/lib/Makefile.in: added removal of CVS directories after install
8637 * doc/Makefile: fixed install, added local_icons
8638 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8639 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8640 * src/ds390/gen.c (genRightShift): fixed bug #870788
8641 * src/SDCCast.c (decorateType): fixed bug #870781
8643 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8645 PIC16 port related changes:
8646 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8647 added variable stackPos,
8649 * gen.c: genCall, assignResultValue: added support for
8650 pushing/retrieving function parameters to/from stack,
8651 genFunction,genEndFunction: setup stack frame for the
8653 genAddrOf: will be changed according to bug 863624
8655 * added files genutils.c and genutils.h which contain gen*
8656 debugged and optimised functions extracted from gen.c
8658 * glue.c: added variable 'externs' which holds extern symbols,
8659 pic16emitRegularMap: is modified to properly handle relocatable
8660 symbols under the new scheme,
8661 pic16createInterruptVect: is modified
8662 pic16printPublics: is modified to emit 'global' assembler directives,
8663 added pic16_printExterns to print extern symbols,
8664 pic16glue: initializes stack/frame pointer in the beginning of
8665 the assembly output. Temporary hack, will be corrected later,
8666 because gplink yet does not support stack and SDCC does not
8667 yet support a type of crt0.o object to create the final binary.
8669 * Removed many lines that contain 8051 legacy code.
8670 * The code is finally placed under a 'code' directive.
8671 * Added port specific options.
8673 * _process_pragma: simplified since now we do not need *special*
8674 include file to define SFR registers. But a separate header
8675 will be needed. This will be developed later.
8676 * _pic16_parseOptions: added, parses port specific options:
8677 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8678 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8679 --preplace-udata-with=
8681 * _pic16_setDefaultOptions: modified to initialize section names,
8682 but hack is temporarly out of order since it needs improvement.
8683 * _pic16_genAssemblerPreamble: configuration words are emitted by
8684 their address instead of their name. This part is incomplete and
8685 supports only the 18Fxx2 devices. Other devices will emit an error
8686 during assembly since they do not contain the same set of config
8688 * _pic16_genIVT: is modified,
8690 * pcode.c: added definitions for some hardware registers that are needed
8692 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8693 All PCI entries are updated. Now LFSR is supported.
8694 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8695 * added pic16_newpCodeOpLit2 to support instructions with
8696 two literal arguments
8697 * pic16_pCode2str: corrected code that emits assembler instructions
8698 with two literal operands and those that have an access bit modifier
8699 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8700 this fixes a bug which caused some labels to be lost, when an
8701 assembler directive was added, i.e. banksel,
8702 * pic16_FixRegisterBanking: improved logic that causes the insertion
8704 * InlineFunction: functions that are called once, are not any more
8705 inlined. This can be a port option in the future,
8707 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8709 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8710 hold the corresponding uninitialized symbols,
8711 * pic16_allocProcessorRegister: registers have explicit marked the
8713 * pic16_allocInternalRegister: registers are explicit marked as
8715 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8716 processing list, so bit registers were lost,
8719 * ralloc.h: added field 'accessBank' and original symbol operand
8720 in register definition,
8721 * removed the field isMapped from register definition,
8723 ** Several functions have been removed from various sources:
8724 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8725 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8726 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8727 pic16_assignRelocatableRegisters
8729 ** others have been introduced:
8730 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8731 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8733 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8735 * support/scripts/inc2h.pl: changed definition of BIT_AT
8736 to emit 'sbit at' instead of 'bit at'. This was a request.
8738 PIC16 port related preliminary changes:
8739 * gen.c: prefixed function popRegFromString with
8740 pic16_ and all references to it corrected
8741 * pcode.c: all pic16_pc_* hardware registers prefixed
8742 with underscore (_),
8743 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8744 * ralloc.c: newReg(): when register is REG_SFR then
8745 set address to rIdx,
8746 pic16_allocProcessorRegister(): marks register wasUsed=0
8747 pic16_writeUsedRegs(): added a call to assign processor
8748 registers via pic16_assignFixedRegisters
8750 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8752 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8753 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8754 variables in unused register banks. Also the SSEG is placed
8755 wherever there is enough space for it, and IDATA can be anywhere
8756 in internal RAM. For now compile using -Wl-Y[stack_size].
8757 The mem file is different for this option as well, since it
8758 makes no sense of talking about DSEG lenght.

9753 and JUMPTABLE iCodes properly now (worked by accident before)
9754 * src/mcs51/gen.c (leftRightUseAcc),
9755 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
9756 iCode properly now. Use getSize instead of nRegs since a & b
9757 aren't part of the nRegs tally.
9759 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
9761 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
9762 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
9763 before instructions that use the _STATUS register
9765 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
9767 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9768 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9769 fetching of the pointer
9770 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9771 copied from genNearPointerSet()
9772 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9773 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9774 If they pop r0/r1 they must be called in the opposite order than aopOp().
9775 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9776 (resp. --stack-auto), prepared for --xstack
9778 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9780 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
9782 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9784 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
9785 these ports have their own __sdcc_external_start()
9787 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9789 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9790 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9791 type for bits was changed. It resulted in bit variables becoming
9792 global, which is not permitted in PIC 14 assembly output.
9794 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9796 * doc/sdccman.lyx: various additions and updates. Rearranged sections
9798 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9800 Z80 and MCS51 linkers complaint if a public symbol is defined
9801 in more than one library module:
9805 * as/mcs51/Makefile.in
9807 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9809 A few small changes that speed up the peephole optimizer.
9813 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9815 Try to make the peephole optimizer smarter by maintaining
9816 an association between the assembly source code and the
9817 iCodes that originated them. Put this information to use
9818 with a new peephole rule condition "notVolatile" so that
9819 the rules can be aggressive yet still safe.
9824 * src/mcs51/peeph.def
9826 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9830 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9831 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9832 if the left or right operand symbols have the accuse flag set.
9834 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9836 Changed the type of the result of the ! (NOT) operator to char;
9837 previously it returned the same type as the source. This allows
9838 us to eliminate all the genFloatNot functions (all of its target
9839 implementations were very buggy) since !float can use the same
9842 * src/SDCCicode.c (ast2iCode): ! returns char
9843 * src/mcs51/gen.c (genNot, genNotFloat),
9844 * src/ds390/gen.c (genNot, genNotFloat),
9845 * src/z80/gen.c (genNot, genNotFloat),
9846 * src/pic/gen.c (genNot, genNotFloat),
9847 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9849 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9851 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9852 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9853 during interrupts. Ensure WSAVE is located at a shared bank address.
9854 2. Fixed page selection in some places
9855 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9856 the registers name strings.
9857 4. Fixed "signed / unsigned compare" compiler warnings.
9858 5. The PIC port manages its own allocation of the general purpose
9859 registers, but makes no attempt to reuse them. As a result when
9860 compiling it soon runs out of general purpose registers. Some
9861 additional code was added to the files pcode.c and device.c to walk
9862 through the function call tree and rename the registers so that they
9872 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9873 genPlus() & genMinus() when the result is the same as left or right

9879 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9881 Made bitfield a distinct type from bit so that bitfields
9882 convert as per ANSI C and bits retain their traditional
9883 boolean style behaviour. Implemented bitfield support in
9891 * src/ds390/gen.c: bit v bitfield split
9892 * src/z80/gen.c: New support for bitfields
9893 * support/regression/tests/bitfields.c: reenabled z80,
9896 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9898 Rules 246.x, 247.x relate to bitfields, the others speed up
9899 access to xdata mapped I/O devices.
9901 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9903 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9905 Cleaned up genPackBits and genUnpackBits and added two helper
9906 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9907 for literal assignments in genPackBits (thanks to Frieder for
9913 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9915 Fixed bug #748310 (pointer to function type mishandled when the
9916 function name is omitted). Also fixed a SIGSEGV when a function
9917 attribute (reentrant, etc) is used on a non-function or on a
9918 function but misplaced before the parameter list.
9920 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9922 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9923 * support/Util/SDCCerr.h,
9924 * support/Util/SDCCerr.c: Added func attr misuse error msg
9926 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9928 Fixed bug #787649 by anonymous
9929 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
9930 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
9932 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9945 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9947 Made the constant following the "interrupt" keyword optional. If
9948 omitted, the function will not automatically be given an entry
9949 in the interrupt vector table (similar to #pragma NOIV, but
9950 less syntacticly kludgy). The interrupt number is also now
9951 range checked. Also fixed a bug in the high order bit example
9958 * support/Util/SDCCerr.c
9959 * support/Util/SDCCerr.h
9962 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9964 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
9965 * src/SDCCicode.c (operandOperation): rewritten some ops
9966 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9967 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9969 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9970 be re-activated by defining REDUCE_LITERALS)
9971 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9972 unsigned, but are signed by default
9973 * src/SDCCval.c (constVal): rearranged
9974 * src/SDCCval.c (valMod): preliminary fix
9975 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10017 constants are unsigned; added recognition of "u" flag for unsigned
10018 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10019 * src/SDCCval.c (valDiv, valMod): fixed signdness

10427 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10428 the regression tests I'm not brave enough to enable 245.b, 245.c
10429 * doc/sdccman.lyx: added latex preamble for hyperref package.
10430 Using pdflatex this will give you a hyperlinked pdf file with

10481 added if/endif conditional macros to remove options help
10482 messages from optionsTable when a port is not configured, added
10483 support for the PIc16 port in the ports table, when executing
10484 the compiler with no port specified on command line, a default
10485 port is selected with the new macro DEFAULT_PORT which is
10486 defined in port.h, in setDefaultOptions() linkOptions is removed
10487 from initialization assignment, since now it is a set,
10488 parseCmdLine uses setParseWithComma for linkOptions, in
10489 linkEdit() linkOptions are accessed with new function indexSet()
10490 which returns the i'th item of a set variable. See SDCCset.c, in
10491 linkEdit() when calling buildCmdLine(), added linkOptions as
10492 last argument. Now users can pass arguments to gplink via the
10493 -Wl option, main() uses pic16glue() to glue up pic16 programs

10506 * src/pic16/main.c: __config directives are commented out to stop
10507 gpasm complaining and test the linkage with gplink, _linkCmd and
10508 _asmCmd changed to be more gplink and gpasm friendly
10509 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10510 produced an error when parsed, peep rule 12 is added to utilize
10511 movff, but it is commented out since the pCode does not support
10512 yet a command with 2 address arguments
10514 2003-05-18 <johan AT balder>
10516 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11588 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11590 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11591 value from option --iram-size.
11593 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11595 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11598 2002-09-18 <wiml AT hhhh.org>
11600 * SDCClrange.h: exposed setFromRange() and setToRange()
11601 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11602 packRegsForAccUse() (bug 542397)
11603 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11604 multiple times and emitting the fetch operations more than once
11605 added aopGetUsesAcc() function to allow binary operators to
11606 fetch their operands in the correct order; made genMinus() emit
11607 compact code for X = LITERAL - Y
11609 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11610 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11611 sprintf() in line 1267.
11613 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11614 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11617 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11618 Changes to aslink (All the changes are marked with 'JCF'):
11620 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11623 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11624 area BSEG. Also moves, if possible, the DATA area down into the internal
11625 ram so more space is available.
11627 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11630 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11631 not bytes. Function summary() which creates a memory usage summary
11632 file with extension .mem. Reports of overlaping stack and small stack
11633 size. If the space for the stack is less than 16 bytes aslink trows a
11636 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11637 the 8051. Option 'y' for memory summary output file.
11639 Changes to sdcc (All the changes are marked with 'JCF'):
11641 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11643 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11644 overlaying area for it (uses RegBankUsed[4]).
11646 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11647 bank zero as used by default. By default aslink locates the stack
11648 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11649 the creation of the .mem file. Delegates the allocation of data area
11650 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11651 the begining of the stack area to aslink.
11653 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11654 glue() in SDCCglue.c creates an area for it.
11656 2002-09-03 Borut Razem <borut.razem AT siol.net>
11657 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11658 sdcc/src/pic/glue.c:
11659 introduced atexit() handler for teporay files removal in case of
11660 errors, assertions, ...
11662 2002-08-29 Borut Razem <borut.razem AT siol.net>
11663 * sdcc/support/cpp2/auto-host_vc_in.h:
11664 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11665 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11666 Maybe there is a similar problem with BORLANDC? It should be checked!
11668 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11669 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11670 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11671 was not executed, and the compiler (cl) launched a warning:
11672 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11674 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11675 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11677 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11678 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11680 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11681 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11682 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11683 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11684 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11685 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11686 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11687 - added Release configuration in VS projects
11688 - review of compiler an linker options
11689 - VC .exe files are generated in bin_vc directory, not to interfere
11690 with binaries generated from other projects (cygwin, mingw, bcc ...)
11692 * sdcc/src/yacc.dsp: added
11694 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11695 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11696 and insert the version number definitions from .version
11698 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11700 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11701 added - genarate auto-host.h using auto-host_vc_in.h as template
11704 removed from CVS, generated automatically
11706 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11707 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11709 2002-08-11 Borut Razem <borut.razem AT siol.net>
11710 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11712 2002-08-10 Borut Razem <borut.razem AT siol.net>
11713 * src/SDCCmain.c (main):
11714 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11715 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11716 The consequence was that some temporary files were not removed.
11719 unification of code in functions tempfilename() and tempfile():
11720 function tempnam() is defined in Visual Studio 6.0 and .NET
11722 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11724 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11725 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11726 - removed compiler command line option /WX: Treats all warnings as errors
11727 - update a list of source files, included into the project
11729 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11730 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11731 changed project type to Generic Project so that can be correcly converted to VS.NET project
11733 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11735 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11737 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11739 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11740 added return 0 statements after assert() to make compiler happy
11742 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11743 added newline in the def file to keep MSC compiler satisfied
11745 * sdcc/src/z80/gen.c:
11746 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11747 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11748 - solved MSC error in function aopDump()
11750 * sdcc_vc.h: define PREFIX as "\\sdcc"
11752 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11753 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11756 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11757 - Rewrote the register banking algorithm.
11758 - Added pCode live-range analysis to registers (for now, only non-used and
11759 singly-used registers optimized away)
11761 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11763 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

11790 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11792 2002-03-28 Johan Knol <johan AT balder>
11794 * src/SDCCval.c: fixed bug #532436
11796 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11798 Added "char *Processor" field to the port structure.
11801 Added -p option. Allows port dependent processor to be specified.
11804 Initialized the new field char *Processor field to NULL in all ports
11807 Compiler generated registers for interrupt context saving
11808 were not getting allocated.
11810 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11813 Fixed left shift. Will promote the left side of a left shift
11814 if a) left shifting more than size of operand or b) when assigned
11815 to something size > size of left side
11817 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11821 analysis is restructured. ...
11823 * src/pic/device.h:
11826 * src/pic/device.c:
11827 Added. device.c is a PIC port hack to accomodate variations
11830 2002-03-13 Michael Hope <michaelh AT vroom>
11832 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11834 2002-03-04 johanknol <johanknol AT manik>
11836 * /src/SDCCval.c: fixed
11838 const unsigned char arr[][2] = { { 0, 1 } };

11925 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11927 * sdcc/src/SDCCloop.c:
11928 Previous fix was not good. basic blocks that have "break" or "return" are
11929 not really partof a loop , but live ranges used in these blocks should
11930 be live thru the entire loop, so set partOfLoop but don't add them to
11933 2002-02-21 <johan AT FRIJA>
11935 * src/SDCCcse.c: fixed bug #514308
11937 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
