6 2006-11-30 Raphael Neider <rneider AT web.de>
8 * src/pic/device.c (create_pic,ram_map): add memRange entries to PIC
9 (pic14_getSharebankSize, pic14_getSharebankAddress): replaced with
10 (pic14_hasSharebank,pic14_isShared,pic14_allRAMShared,
11 pic14_getSharedStack): NEW, evaluate the memRange entries to locate
12 a sharebank, use a non-shared bank for the stack if none available
13 * src/pic/device.h (struct memRange): added linked list next field,
14 added prototypes for above functions
15 * src/pic/ralloc.c (initStack): handle shared and banked stacks,
16 (typeRegWithIdx): accept fixed and unfixed stack registers

20 (FixRegisterBanking): added optimization for devices with only one
21 possibly aliased bank of memory, like 16f84
22 * src/pic/glue.c (pic14_constructAbsMap): back to udata_ovr, as some
23 devices have no SHAREBANK in the linker script

31 genAnd, genOr, genXor, genLeftShiftLiteral, genRightShiftLiteral,
32 genhc08Code): switched most of the D (debug) macros to DD (detailed
33 debug) macros to better control clutter in the generated .asm file.
34 * src/hc08/gen.c: (forceStackedAop, genUminus, genLeftShift,
35 genRightShift): fixed bug with non-constant bit shift stored to
36 a volatile result (SF Open Discussion forum thread #1616749).
37 Single byte case is not yet optimized.

1940 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1942 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1943 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1945 One basic decision: e.g. src/clean.mk includes further files. In order
1946 to make this work there are two solutions:
1947 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1948 run configure on them. This way they can use
1949 'include $(srcdir)/port-clean.mk'
1950 - always include clean.mk by the Makefile at the same level. To avoid
1951 that `make clean` tries to include and build Makefile.dep the
1952 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1953 implemented, because now even `make uninstall` doesn't create
1954 Makefile.in. clean.mk could be eliminated by pasting it in
1957 * debugger/mcs51/Makefile.in: build own objects from library sources
1958 (SLIB, SDCC) in current directory
1960 * configure, configure.in: renamed --disable-device-lib-build in
1961 --disable-device-lib; added --enable-doc, the required tools are
1962 searched by configure; added result message; the toolchain for the
1963 belonging ports are now only built, if the port is enabled.
1965 * support/regression/*: all output is written in directory gen, because
1966 the fwk and ports directories don't livet in the build tree using vpath
1968 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1969 --disable-device-lib, added --enable-doc, added section VPATH
1971 * sim/ucsim/configure.in,
1972 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1973 z80 are enabled by default
1975 2006-04-24 Raphael Neider <rneider AT web.de>
1977 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1978 to config word, "pic14_"-prefixed some extern functions
1979 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1980 config word has been found
1981 * src/pic/device.h: added prototypes
1982 * src/pic/pcode.c: added "pic14_"-prefix where needed
1983 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1985 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1988 (pic14createInterruptVect): moved generating __config directives away

1999 fixes #1469504 and #1474602,
2000 (pCodeRegOptimizeRegUsage): fixed typo in comment

2223 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
2225 * src/mcs51/gen.c (genCall): fixed bug 1457608
2227 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

2232 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
2234 * src/SDCCpeeph.c (operandsLiteral): new, added,

2245 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
2246 implemented patch 1120823 Thanks to Willy De la Court (normal
2247 interrupts need an interrupt number now if they are made critical),
2248 and enabled nesting of critical functions though not for gbz80
2249 (genCritical, genEndCritical): added functions
2250 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2251 * src/z80/mappings.i: added "ei" to all mappings
2253 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

2256 submitted by the Debian SDCC maintainer Aurelien Jarno:
2257 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
2258 archive with gcc 4.1 on mips and wrote the patch"
2260 2006-03-16 Raphael Neider <rneider AT web.de>
2262 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
2263 the left operand is shorter than the result (c* = lit-c* + int),
2265 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2268 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2270 * src/.version: increased version number to 2.5.5
2271 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2272 linking is done manually in pic16 port's _linkEdit,
2273 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2274 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2275 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2276 allocate asmop as AOP_ACC,
2277 (aopForRemat): added parameter 'bool result' in function declaration,
2278 (pic16_aopGet): return AOP_ACC when accessing WREG,
2279 (pic16_popGetTempReg): minor modification,
2280 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2281 'pic16_allocWithIdx',
2282 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
2283 calling function in absolute addresses,
2284 (genAssign): take into account AOP_ACC asmop,
2285 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
2286 * src/pic16/pcoderegs.c: some debug functions and lines added,
2287 * src/pic16/ralloc.c (decodeRegType): added but commented out,
2288 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2290 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2291 call to allocReg, not by manually allocating a new one,
2292 (pic16_assignRegisters): now before going through the register
2293 allocating functions mark all registers as free. This eliminates some
2294 side effects resulting from peephole parser done earlier in the backbone
2296 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
2298 * src/SDCCicode.c (geniCodeLogic),

2317 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
2318 (aopForSym, aopOp): increment asmop.allocated if reused,
2319 (freeAsmop): decrement asmop.allocated and check for zero instead of
2321 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2322 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
2323 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

2346 2006-03-06 Borut Razem <borut.razem AT siol.net>
2348 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2349 made the linker quiet
2351 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2353 * src/pic16/gen.c (genPcall): fixed bug #1443644
2354 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2355 which dumps before the function entry point a data byte which represents
2356 the number of the local variables used by the specified function, added
2357 'xinst' for initial support for Extended Instruction Support,
2358 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2359 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2360 port->fun_prefix anymore (may change later),
2361 (genFunction, genEndFunction): do not store/restore local registers for
2362 _main (this should take care the --main-return command line option in
2364 (genOr): removed some legacy pic-port instructions,
2365 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2366 performing operations with SFR's causes data to be written more than
2367 once to each SFR. Perhaps SFRs should be handled in special cases...
2368 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2370 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2371 into account for stack starting position,
2372 (struct OPTIONS pic16_optionsTable): added command line argument
2373 --extended or -y for Extended Instruction Support,
2374 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2375 (deassignLRs): *** perhaps the most important change, old 'for' code
2376 (commented out for reference), didn't account for some registers which
2377 were left marked 'not free' after a pointer operation. The change
2378 reduces register usage a lot in some cases
2380 2006-03-04 Borut Razem <borut.razem AT siol.net>

4705 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
4706 immedDom() returning wrong block; probably fixes bug #1160833)
4708 2005-03-20 Borut Razem <borut.razem AT siol.net>
4710 * support/scripts/inc2h.pl: WIN32 port
4712 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4714 * device/lib/makefile.in: added abs.c and labs.c
4716 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4718 * device/include/stdint.h: added
4719 * device/lib/abs.c: added
4720 * device/lib/labs.c: added
4721 * device/include/stdlib.h: added abs() and labs() prototypes
4722 * device/lib/libsdcc.lib: added abs and labs
4723 * device/include/float.h,
4724 * device/lib/_fsmul.c,
4725 * device/lib/printf_fast.c,
4726 * device/lib/printf_tiny.c: updated comments
4728 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4730 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4733 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4735 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4736 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4738 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4740 * device/lib/printf_large.c: removed inline assembly for portability and
4741 readability. Use printf_fast if speed or size are more important.
4742 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4743 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4745 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4747 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4748 prevent compiler warning
4750 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4752 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4753 moved to level 0 and declared as static. Also they are explicit
4754 placed in access bank. This was necessery because some times they
4755 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4756 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4757 optimizations. Currently only compare to unsigned char is implemented,
4758 * src/pic16/gen.c: added fReturnIdx array,
4759 * (struct resolvedIfx) is moved to gen.h and made public,
4760 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4761 * (aopForSym): added an optimization to directly store in stack of
4762 the operand of a SEND iCode,
4763 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4764 but as registers instead (AOP_REG) using the fReturnIdx array,
4765 * (pic16_freeAsmop): remove the freed register from the
4766 _G.sregsAlloc field,
4767 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4768 a compare of 'WREG',
4769 * (pic16_popGetTempRegCond): changed function prototype, now
4770 function takes also a bitVector argument v which holds the current
4771 set of registers that are allocated for stack access by aopForSym,
4772 registers allocated in aopForSym for accessing stack symbols are not
4773 any more part of the functions usedRegs field,
4774 * (genCall): some times aopOp is called for a stack variable to be
4775 send, aopForSym might perform the push, if this is true make sure
4776 that genCall doesn't push the variable twice by testing _G.resDirect,
4777 * (genFunction): changed testing for unspecified interrupt number
4778 from 256 to INTNO_UNSPEC,
4779 * modified selection scheme of frame pointer generation. Previously
4780 if function did use local registers a frame pointer was generated,
4781 now a frame pointer is generated only if function has arguments
4782 (that need PLUSW2 register access), or has stack arguments, or the
4783 compiler is not instructed to omit the frame pointer,
4784 * (genEndFunction): before restoring local registers that were saved
4785 in the function preamble, also restore the registers that *might*
4786 have been allocated for stack access,
4787 * (genRet): removed some old comments,
4788 * (genCmp, the active (RN's) version): added a call to the
4789 pic16_genCmp_special function to perform the compare with a more
4790 robust and optimized way,
4791 * (genInline): a feature has been added in inline code generation,
4792 which allows a wildcard variable substitution when writing inline
4793 assembly. Code is incomplete and experimental therefore undocumented,
4794 * (genCast): changed order of aopOp for result and right to allow
4795 aopForSym to directly load the result if possible,
4796 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4797 perform an optimized compare on some selected special occasions,
4798 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4799 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4800 generate an IVT any more,
4801 * src/pic16/main.c (pic16_optionsTable): added command line option
4803 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4804 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4806 * src/pic16/NOTES: Raphael Neider added in list of active developers
4807 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4808 jumptable_end to prevent bug #,
4809 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4810 inCond and outCond fields,
4811 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4812 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4813 turn off register spilling,
4814 * (packRegsForOneUse): synced with other ports' versions although it
4815 is not used currently,
4816 * (pic16_packRegisters): added an optimization while reading
4817 structure bitfields, some registers may be saved (malloc code is
4818 decreased by 80 bytes)
4820 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4822 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4823 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4824 this can be optimized more?
4826 2005-03-10 Raphael Neider <rneider AT web.de>
4828 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4829 genNearPointerGet): (hopefully) fixed access to bitfields via
4830 pointers (p->bitN = x; and x = p->bitN; failed)
4832 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5465 generated for switch statements. For now you need to set the
5466 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5467 Now 4 algorithms for mcs51 jumptable generation are used:
5468 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

5502 * added libc directory. The current version of LibC contains string
5503 functions, ctype functions and macros and some functions of the
5504 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5505 be extensively tested in the future. Standard disclaimer here.
5506 Library is not automatically build yet. But one can build it by

5518 * (pic16_storeForReturn): optimized return of 0,
5519 * (genCmp): experimental code for new genCmp which uses PIC18's
5520 special compare&skip instructions. Initial tests fail some times
5521 with variables grater than 1 byte in size, so new code is disabled,
5522 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5524 * (genCast): began a fix to optimize the casting of a bit to another
5525 bit, now assigning a bitfield to another bitfield will fail, sorry,

5534 and 1 for banking instruction,
5535 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5536 caused stop processing pCodes after a inline assembly block,

5539 registers when it shouldn't,
5540 * src/pic16/ralloc.c (allocReg): add preliminary support for
5541 supporting a limited set of temporary registers,
5543 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5549 (genFunction): optimize RECEIVE iCodes in reentrant functions
5551 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5553 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5567 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
5569 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

8503 code / RAM are in the same page / bank. This means the linker can
8504 safely allocate code/RAM of separate ASM files to different pages/banks.
8505 * doc/sdccman.lyx: added Slade's tips
8506 * src/mcs51/peeph.def: fixed bug #880768

8548 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8550 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8551 loaded with the linker search paths (-L arguments) and the libraries
8552 to be linked with the current source (-l arguments). Changes
8553 currently will affect only the pic16 port.
8554 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8555 include path the port specific paths and port specific libraries,
8556 * gplink command now contains the $3 argument,
8557 * src/pic16/device.h,
8558 * src/pic16/device.c,: structure PIC_device is made public and
8559 renamed to PIC16_device, the same for variable Pics which is renamed

8574 Documenting changes from previous commits.
8575 * configure.in (version 1.56),
8576 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8577 when generating output files to configure the pic16 library,
8578 but now I've commented it out, since gputils aren't installed in the
8579 SF compile farm, so library won't compile
8581 * device/lib/Makefile.in (version 1.56): initially I've added in
8582 target 'all' the prerequestive 'model-pic16' so it compiled the
8583 pic16 library, but now I've commented it out for the same reasons
8585 * added targets 'model-pic16' and 'objects-pic16' to compile the
8587 * added target 'port-specific-objects-pic16' to handle the
8588 generated libraries and copy them into the build/ directory
8589 * added target 'clean-intermediate-pic16' to clean intermediate
8590 files into pic16 directory
8591 * in target 'installdirs' added line to create directory pic16 in
8592 the installation path
8594 * device/include/Makefile.in (version 1.11): in target 'install'
8595 added lines to copy all header files to installation path,
8596 * in target 'installdirs' added line create directory for pic16
8597 headers in the installation path

8612 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8613 option so that it actually works. Made it specific to the z80, since
8614 the gbz80 doesn't have these kinds of I/O ports.
8616 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8618 * device/include/z180.h,

8640 Mainly changes to support compilation of the device libraries
8641 * src/pic16/device.c: stack is allocated via symbol and not
8642 via literal number. The symbol is placed in the corresponding
8643 position of the data ram
8644 * (pic16_dump_section): relocatable and absolute uninitialized
8645 data are now emitted in sorted order to reduce section naming,
8646 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8647 weren't marked as being in the access bank,
8649 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8651 Added portion of GNU PIC Library under the directory
8652 device/include/pic16 and device/lib/pic16. These files
8653 contain the declarations of SFRs for the PIC18Fxx2 devices.
8654 The directory is initialized via configure from toplevel.
8656 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8658 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

8665 2004-01-12 Borut Razem <borut.razem AT siol.net>
8667 * src/SDCC.lex, support/Util/SDCCerr.h, support/Util/SDCCerr.c,
8668 doc/sdccman.lyx: upper case pragmas are deprecated
8670 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
8672 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results

8683 * doc/sdccman.lyx: Moved and added some sections, small changes
8684 all over. Telling LaTeX to be less strict with word spacing
8685 to better keep the right margin. Changed some notes about
8686 maintainance of the ports in section 3.2.1 - is it OK like this?
8688 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
8690 SDCC source changes:
8691 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

8697 processor registers declared internally by the port are emitted in
8698 the translation as equates,
8699 * src/pic16/gen.c: inline code is passed unprocessed to the

8840 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8842 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8843 (default behaviour).
8845 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8847 A python script to validate compiler diagnostic messages. It can be
8848 used to verify that sdcc complains about bad c source code and
8849 gives a good location of the error.
8850 * support/valdiag/Makefile,
8851 * support/valdiag/valdiag.py,

8869 Bug reported from Jesus Calvino-Fraga
8871 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8873 * sdcc.spec: updated
8874 * device/include/Makefile.in: don't install CVS directories
8875 * device/lib/Makefile.in: added removal of CVS directories after install
8876 * doc/Makefile: fixed install, added local_icons
8877 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8878 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8879 * src/ds390/gen.c (genRightShift): fixed bug #870788
8880 * src/SDCCast.c (decorateType): fixed bug #870781
8882 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8884 PIC16 port related changes:
8885 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8886 added variable stackPos,
8888 * gen.c: genCall, assignResultValue: added support for
8889 pushing/retrieving function parameters to/from stack,
8890 genFunction,genEndFunction: setup stack frame for the
8892 genAddrOf: will be changed according to bug 863624
8894 * added files genutils.c and genutils.h which contain gen*
8895 debugged and optimised functions extracted from gen.c
8897 * glue.c: added variable 'externs' which holds extern symbols,
8898 pic16emitRegularMap: is modified to properly handle relocatable
8899 symbols under the new scheme,
8900 pic16createInterruptVect: is modified
8901 pic16printPublics: is modified to emit 'global' assembler directives,
8902 added pic16_printExterns to print extern symbols,
8903 pic16glue: initializes stack/frame pointer in the beginning of
8904 the assembly output. Temporary hack, will be corrected later,
8905 because gplink yet does not support stack and SDCC does not
8906 yet support a type of crt0.o object to create the final binary.
8908 * Removed many lines that contain 8051 legacy code.
8909 * The code is finally placed under a 'code' directive.
8910 * Added port specific options.
8912 * _process_pragma: simplified since now we do not need *special*
8913 include file to define SFR registers. But a separate header
8914 will be needed. This will be developed later.
8915 * _pic16_parseOptions: added, parses port specific options:
8916 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8917 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8918 --preplace-udata-with=
8920 * _pic16_setDefaultOptions: modified to initialize section names,
8921 but hack is temporarly out of order since it needs improvement.
8922 * _pic16_genAssemblerPreamble: configuration words are emitted by
8923 their address instead of their name. This part is incomplete and
8924 supports only the 18Fxx2 devices. Other devices will emit an error
8925 during assembly since they do not contain the same set of config
8927 * _pic16_genIVT: is modified,
8929 * pcode.c: added definitions for some hardware registers that are needed
8931 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8932 All PCI entries are updated. Now LFSR is supported.
8933 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8934 * added pic16_newpCodeOpLit2 to support instructions with
8935 two literal arguments
8936 * pic16_pCode2str: corrected code that emits assembler instructions
8937 with two literal operands and those that have an access bit modifier
8938 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8939 this fixes a bug which caused some labels to be lost, when an
8940 assembler directive was added, i.e. banksel,
8941 * pic16_FixRegisterBanking: improved logic that causes the insertion
8943 * InlineFunction: functions that are called once, are not any more
8944 inlined. This can be a port option in the future,
8946 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8948 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8949 hold the corresponding uninitialized symbols,
8950 * pic16_allocProcessorRegister: registers have explicit marked the
8952 * pic16_allocInternalRegister: registers are explicit marked as
8954 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8955 processing list, so bit registers were lost,
8958 * ralloc.h: added field 'accessBank' and original symbol operand
8959 in register definition,
8960 * removed the field isMapped from register definition,
8962 ** Several functions have been removed from various sources:
8963 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8964 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8965 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8966 pic16_assignRelocatableRegisters
8968 ** others have been introduced:
8969 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8970 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8972 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8974 * support/scripts/inc2h.pl: changed definition of BIT_AT
8975 to emit 'sbit at' instead of 'bit at'. This was a request.
8977 PIC16 port related preliminary changes:
8978 * gen.c: prefixed function popRegFromString with
8979 pic16_ and all references to it corrected
8980 * pcode.c: all pic16_pc_* hardware registers prefixed
8981 with underscore (_),
8982 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8983 * ralloc.c: newReg(): when register is REG_SFR then
8984 set address to rIdx,
8985 pic16_allocProcessorRegister(): marks register wasUsed=0
8986 pic16_writeUsedRegs(): added a call to assign processor
8987 registers via pic16_assignFixedRegisters
8989 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8991 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8992 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8993 variables in unused register banks. Also the SSEG is placed
8994 wherever there is enough space for it, and IDATA can be anywhere
8995 in internal RAM. For now compile using -Wl-Y[stack_size].
8996 The mem file is different for this option as well, since it
8997 makes no sense of talking about DSEG lenght.
8999 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9001 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9002 in certain cases, e.g. when ROM assignment, patch provided
9003 from Albert den Haan.
9005 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9146 xdata and data memory on startup. Set the environment variable
9147 SDCC_NOGENRAMCLEAR to disable this.
9148 * src/mcs51/peephole.def,
9149 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
9150 (allows non-interrupt and interrupt code to safely compete for a resource
9151 without the non-interrupt code having to disable interrupts)
9153 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9911 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9913 Fixed bug #621531 (const & volatile confusion in the type chain).
9914 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
9915 refer to the const or volatile state of the pointer itself.

9992 and JUMPTABLE iCodes properly now (worked by accident before)
9993 * src/mcs51/gen.c (leftRightUseAcc),
9994 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
9995 iCode properly now. Use getSize instead of nRegs since a & b
9996 aren't part of the nRegs tally.
9998 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10000 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10002 before instructions that use the _STATUS register
10004 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
10006 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
10007 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for

10010 copied from genNearPointerSet()
10011 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10012 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10013 If they pop r0/r1 they must be called in the opposite order than aopOp().
10014 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10015 (resp. --stack-auto), prepared for --xstack
10017 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

10028 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10029 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10030 type for bits was changed. It resulted in bit variables becoming
10031 global, which is not permitted in PIC 14 assembly output.
10033 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10035 * doc/sdccman.lyx: various additions and updates. Rearranged sections

10046 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10048 A few small changes that speed up the peephole optimizer.
10052 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10054 Try to make the peephole optimizer smarter by maintaining
10055 an association between the assembly source code and the
10056 iCodes that originated them. Put this information to use
10057 with a new peephole rule condition "notVolatile" so that
10058 the rules can be aggressive yet still safe.
10063 * src/mcs51/peeph.def
10065 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10069 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10070 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10071 if the left or right operand symbols have the accuse flag set.
10073 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10075 Changed the type of the result of the ! (NOT) operator to char;
10076 previously it returned the same type as the source. This allows
10077 us to eliminate all the genFloatNot functions (all of its target
10078 implementations were very buggy) since !float can use the same
10081 * src/SDCCicode.c (ast2iCode): ! returns char

10090 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10091 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10092 during interrupts. Ensure WSAVE is located at a shared bank address.
10093 2. Fixed page selection in some places
10094 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10095 the registers name strings.
10096 4. Fixed "signed / unsigned compare" compiler warnings.
10097 5. The PIC port manages its own allocation of the general purpose
10098 registers, but makes no attempt to reuse them. As a result when
10099 compiling it soon runs out of general purpose registers. Some
10100 additional code was added to the files pcode.c and device.c to walk
10101 through the function call tree and rename the registers so that they
10111 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10112 genPlus() & genMinus() when the result is the same as left or right

10118 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10120 Made bitfield a distinct type from bit so that bitfields
10121 convert as per ANSI C and bits retain their traditional
10122 boolean style behaviour. Implemented bitfield support in
10130 * src/ds390/gen.c: bit v bitfield split
10131 * src/z80/gen.c: New support for bitfields
10132 * support/regression/tests/bitfields.c: reenabled z80,
10135 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10137 Rules 246.x, 247.x relate to bitfields, the others speed up
10138 access to xdata mapped I/O devices.
10140 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10142 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10144 Cleaned up genPackBits and genUnpackBits and added two helper
10145 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10146 for literal assignments in genPackBits (thanks to Frieder for
10152 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10154 Fixed bug #748310 (pointer to function type mishandled when the
10155 function name is omitted). Also fixed a SIGSEGV when a function
10156 attribute (reentrant, etc) is used on a non-function or on a
10157 function but misplaced before the parameter list.
10159 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10161 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10162 * support/Util/SDCCerr.h,
10163 * support/Util/SDCCerr.c: Added func attr misuse error msg
10165 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10167 Fixed bug #787649 by anonymous
10168 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10169 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10171 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10184 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10186 Made the constant following the "interrupt" keyword optional. If
10187 omitted, the function will not automatically be given an entry

10722 support for the PIc16 port in the ports table, when executing
10723 the compiler with no port specified on command line, a default
10724 port is selected with the new macro DEFAULT_PORT which is
10725 defined in port.h, in setDefaultOptions() linkOptions is removed
10726 from initialization assignment, since now it is a set,
10727 parseCmdLine uses setParseWithComma for linkOptions, in
10728 linkEdit() linkOptions are accessed with new function indexSet()
10729 which returns the i'th item of a set variable. See SDCCset.c, in
10730 linkEdit() when calling buildCmdLine(), added linkOptions as
10731 last argument. Now users can pass arguments to gplink via the
10732 -Wl option, main() uses pic16glue() to glue up pic16 programs
10733 * src/SDCCpeeph.c: various changes to support pic16

10746 gpasm complaining and test the linkage with gplink, _linkCmd and
10747 _asmCmd changed to be more gplink and gpasm friendly
10748 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10749 produced an error when parsed, peep rule 12 is added to utilize
10750 movff, but it is commented out since the pCode does not support
10751 yet a command with 2 address arguments

11813 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11814 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11816 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11818 * in /sdcc/as/mcs51/ changed these files in order to create an
11819 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11820 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11821 following files to include the previous two files: aslink.dsp,
11822 Makefile.aslink, Makefile.bcc, and Makefile.in.
11824 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11825 .adb instead of .cdb
11827 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11829 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11830 value from option --iram-size.
11832 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11834 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11837 2002-09-18 <wiml AT hhhh.org>
11839 * SDCClrange.h: exposed setFromRange() and setToRange()
11840 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11841 packRegsForAccUse() (bug 542397)
11842 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11843 multiple times and emitting the fetch operations more than once
11844 added aopGetUsesAcc() function to allow binary operators to
11845 fetch their operands in the correct order; made genMinus() emit
11846 compact code for X = LITERAL - Y
11848 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11849 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11850 sprintf() in line 1267.
11852 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11853 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11856 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11857 Changes to aslink (All the changes are marked with 'JCF'):
11859 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11862 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11863 area BSEG. Also moves, if possible, the DATA area down into the internal
11864 ram so more space is available.
11866 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11869 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11870 not bytes. Function summary() which creates a memory usage summary
11871 file with extension .mem. Reports of overlaping stack and small stack
11872 size. If the space for the stack is less than 16 bytes aslink trows a
11875 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11876 the 8051. Option 'y' for memory summary output file.
11878 Changes to sdcc (All the changes are marked with 'JCF'):
11880 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11882 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11883 overlaying area for it (uses RegBankUsed[4]).
11885 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11886 bank zero as used by default. By default aslink locates the stack
11887 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11888 the creation of the .mem file. Delegates the allocation of data area
11889 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11890 the begining of the stack area to aslink.
11892 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11893 glue() in SDCCglue.c creates an area for it.
11895 2002-09-03 Borut Razem <borut.razem AT siol.net>
11896 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11897 sdcc/src/pic/glue.c:
11898 introduced atexit() handler for teporay files removal in case of
11899 errors, assertions, ...
11901 2002-08-29 Borut Razem <borut.razem AT siol.net>
11902 * sdcc/support/cpp2/auto-host_vc_in.h:
11903 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11904 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11905 Maybe there is a similar problem with BORLANDC? It should be checked!
11907 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11908 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11909 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11910 was not executed, and the compiler (cl) launched a warning:
11911 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11913 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11914 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11916 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11917 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11919 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11920 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

11923 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11924 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11925 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11926 - added Release configuration in VS projects
11927 - review of compiler an linker options
11928 - VC .exe files are generated in bin_vc directory, not to interfere
11929 with binaries generated from other projects (cygwin, mingw, bcc ...)
11931 * sdcc/src/yacc.dsp: added
11933 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11934 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11935 and insert the version number definitions from .version
11937 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11939 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11940 added - genarate auto-host.h using auto-host_vc_in.h as template
11943 removed from CVS, generated automatically
11945 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11946 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11948 2002-08-11 Borut Razem <borut.razem AT siol.net>
11949 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11951 2002-08-10 Borut Razem <borut.razem AT siol.net>
11952 * src/SDCCmain.c (main):
11953 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11954 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11955 The consequence was that some temporary files were not removed.
11958 unification of code in functions tempfilename() and tempfile():
11959 function tempnam() is defined in Visual Studio 6.0 and .NET
11961 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11963 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11964 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11965 - removed compiler command line option /WX: Treats all warnings as errors
11966 - update a list of source files, included into the project
11968 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11969 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11970 changed project type to Generic Project so that can be correcly converted to VS.NET project

11985 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11986 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11987 - solved MSC error in function aopDump()

12167 Previous fix was not good. basic blocks that have "break" or "return" are
12168 not really partof a loop , but live ranges used in these blocks should

13045 * device/lib/gbz80/crt0.s (init): Fixed up support for the gbz80 such that it will at least run (and fail badly) the regression tests.
13047 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
13049 2001-08-29 Michael Hope <michaelh AT juju.net.nz>
