15 (pic14_hasSharebank,pic14_isShared,pic14_allRAMShared,
16 pic14_getSharedStack): NEW, evaluate the memRange entries to locate
17 a sharebank, use a non-shared bank for the stack if none available
18 * src/pic/device.h (struct memRange): added linked list next field,
19 added prototypes for above functions
20 * src/pic/ralloc.c (initStack): handle shared and banked stacks,

25 (FixRegisterBanking): added optimization for devices with only one
26 possibly aliased bank of memory, like 16f84
27 * src/pic/glue.c (pic14_constructAbsMap): back to udata_ovr, as some

40 genRightShift): fixed bug with non-constant bit shift stored to
41 a volatile result (SF Open Discussion forum thread #1616749).

1945 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1947 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1948 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1950 One basic decision: e.g. src/clean.mk includes further files. In order
1951 to make this work there are two solutions:
1952 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1953 run configure on them. This way they can use
1954 'include $(srcdir)/port-clean.mk'
1955 - always include clean.mk by the Makefile at the same level. To avoid
1956 that `make clean` tries to include and build Makefile.dep the
1957 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1958 implemented, because now even `make uninstall` doesn't create
1959 Makefile.in. clean.mk could be eliminated by pasting it in
1962 * debugger/mcs51/Makefile.in: build own objects from library sources
1963 (SLIB, SDCC) in current directory
1965 * configure, configure.in: renamed --disable-device-lib-build in
1966 --disable-device-lib; added --enable-doc, the required tools are
1967 searched by configure; added result message; the toolchain for the
1968 belonging ports are now only built, if the port is enabled.
1970 * support/regression/*: all output is written in directory gen, because
1971 the fwk and ports directories don't livet in the build tree using vpath
1973 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1974 --disable-device-lib, added --enable-doc, added section VPATH
1976 * sim/ucsim/configure.in,
1977 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1978 z80 are enabled by default
1980 2006-04-24 Raphael Neider <rneider AT web.de>
1982 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1983 to config word, "pic14_"-prefixed some extern functions
1984 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1985 config word has been found
1986 * src/pic/device.h: added prototypes
1987 * src/pic/pcode.c: added "pic14_"-prefix where needed
1988 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1990 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2005 (pCodeRegOptimizeRegUsage): fixed typo in comment

2228 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
2230 * src/mcs51/gen.c (genCall): fixed bug 1457608
2232 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

2237 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
2239 * src/SDCCpeeph.c (operandsLiteral): new, added,

2250 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
2251 implemented patch 1120823 Thanks to Willy De la Court (normal
2252 interrupts need an interrupt number now if they are made critical),
2253 and enabled nesting of critical functions though not for gbz80
2254 (genCritical, genEndCritical): added functions
2255 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2256 * src/z80/mappings.i: added "ei" to all mappings
2258 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2260 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
2261 submitted by the Debian SDCC maintainer Aurelien Jarno:
2262 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
2263 archive with gcc 4.1 on mips and wrote the patch"
2265 2006-03-16 Raphael Neider <rneider AT web.de>
2267 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
2268 the left operand is shorter than the result (c* = lit-c* + int),
2270 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2273 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2275 * src/.version: increased version number to 2.5.5
2276 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2277 linking is done manually in pic16 port's _linkEdit,
2278 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2279 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2280 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2281 allocate asmop as AOP_ACC,
2282 (aopForRemat): added parameter 'bool result' in function declaration,
2283 (pic16_aopGet): return AOP_ACC when accessing WREG,
2284 (pic16_popGetTempReg): minor modification,
2285 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2286 'pic16_allocWithIdx',
2287 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
2288 calling function in absolute addresses,
2289 (genAssign): take into account AOP_ACC asmop,
2290 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,

2293 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2295 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2296 call to allocReg, not by manually allocating a new one,
2297 (pic16_assignRegisters): now before going through the register
2298 allocating functions mark all registers as free. This eliminates some
2299 side effects resulting from peephole parser done earlier in the backbone
2301 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
2303 * src/SDCCicode.c (geniCodeLogic),

2322 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
2323 (aopForSym, aopOp): increment asmop.allocated if reused,
2324 (freeAsmop): decrement asmop.allocated and check for zero instead of
2326 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2327 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
2328 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

2351 2006-03-06 Borut Razem <borut.razem AT siol.net>
2353 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2354 made the linker quiet
2356 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2358 * src/pic16/gen.c (genPcall): fixed bug #1443644
2359 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2360 which dumps before the function entry point a data byte which represents
2361 the number of the local variables used by the specified function, added
2362 'xinst' for initial support for Extended Instruction Support,
2363 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2364 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2365 port->fun_prefix anymore (may change later),
2366 (genFunction, genEndFunction): do not store/restore local registers for
2367 _main (this should take care the --main-return command line option in
2369 (genOr): removed some legacy pic-port instructions,
2370 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2371 performing operations with SFR's causes data to be written more than
2372 once to each SFR. Perhaps SFRs should be handled in special cases...
2373 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2375 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2376 into account for stack starting position,
2377 (struct OPTIONS pic16_optionsTable): added command line argument
2378 --extended or -y for Extended Instruction Support,
2379 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2380 (deassignLRs): *** perhaps the most important change, old 'for' code
2381 (commented out for reference), didn't account for some registers which
2382 were left marked 'not free' after a pointer operation. The change
2383 reduces register usage a lot in some cases
2385 2006-03-04 Borut Razem <borut.razem AT siol.net>

4709 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
4710 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
4711 immedDom() returning wrong block; probably fixes bug #1160833)
4713 2005-03-20 Borut Razem <borut.razem AT siol.net>
4715 * support/scripts/inc2h.pl: WIN32 port
4717 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4719 * device/lib/makefile.in: added abs.c and labs.c
4721 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4723 * device/include/stdint.h: added
4724 * device/lib/abs.c: added
4725 * device/lib/labs.c: added
4726 * device/include/stdlib.h: added abs() and labs() prototypes
4727 * device/lib/libsdcc.lib: added abs and labs
4728 * device/include/float.h,
4729 * device/lib/_fsmul.c,
4730 * device/lib/printf_fast.c,
4731 * device/lib/printf_tiny.c: updated comments
4733 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4735 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4738 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4740 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4741 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4743 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4745 * device/lib/printf_large.c: removed inline assembly for portability and
4746 readability. Use printf_fast if speed or size are more important.
4747 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4748 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4750 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4752 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4753 prevent compiler warning
4755 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4757 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4758 moved to level 0 and declared as static. Also they are explicit
4759 placed in access bank. This was necessery because some times they
4760 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4761 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4762 optimizations. Currently only compare to unsigned char is implemented,
4763 * src/pic16/gen.c: added fReturnIdx array,
4764 * (struct resolvedIfx) is moved to gen.h and made public,
4765 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4766 * (aopForSym): added an optimization to directly store in stack of
4767 the operand of a SEND iCode,
4768 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4769 but as registers instead (AOP_REG) using the fReturnIdx array,
4770 * (pic16_freeAsmop): remove the freed register from the
4771 _G.sregsAlloc field,
4772 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4773 a compare of 'WREG',
4774 * (pic16_popGetTempRegCond): changed function prototype, now
4775 function takes also a bitVector argument v which holds the current
4776 set of registers that are allocated for stack access by aopForSym,
4777 registers allocated in aopForSym for accessing stack symbols are not
4778 any more part of the functions usedRegs field,
4779 * (genCall): some times aopOp is called for a stack variable to be
4780 send, aopForSym might perform the push, if this is true make sure
4781 that genCall doesn't push the variable twice by testing _G.resDirect,
4782 * (genFunction): changed testing for unspecified interrupt number
4783 from 256 to INTNO_UNSPEC,
4784 * modified selection scheme of frame pointer generation. Previously
4785 if function did use local registers a frame pointer was generated,
4786 now a frame pointer is generated only if function has arguments
4787 (that need PLUSW2 register access), or has stack arguments, or the
4788 compiler is not instructed to omit the frame pointer,
4789 * (genEndFunction): before restoring local registers that were saved
4790 in the function preamble, also restore the registers that *might*
4791 have been allocated for stack access,
4792 * (genRet): removed some old comments,
4793 * (genCmp, the active (RN's) version): added a call to the
4794 pic16_genCmp_special function to perform the compare with a more
4795 robust and optimized way,
4796 * (genInline): a feature has been added in inline code generation,
4797 which allows a wildcard variable substitution when writing inline
4798 assembly. Code is incomplete and experimental therefore undocumented,
4799 * (genCast): changed order of aopOp for result and right to allow
4800 aopForSym to directly load the result if possible,
4801 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4802 perform an optimized compare on some selected special occasions,
4803 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4804 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4805 generate an IVT any more,
4806 * src/pic16/main.c (pic16_optionsTable): added command line option
4808 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4809 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4811 * src/pic16/NOTES: Raphael Neider added in list of active developers
4812 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4813 jumptable_end to prevent bug #,
4814 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4815 inCond and outCond fields,
4816 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4817 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4818 turn off register spilling,
4819 * (packRegsForOneUse): synced with other ports' versions although it
4820 is not used currently,
4821 * (pic16_packRegisters): added an optimization while reading
4822 structure bitfields, some registers may be saved (malloc code is
4823 decreased by 80 bytes)
4825 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4827 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4828 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4829 this can be optimized more?
4831 2005-03-10 Raphael Neider <rneider AT web.de>
4833 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4834 genNearPointerGet): (hopefully) fixed access to bitfields via
4835 pointers (p->bitN = x; and x = p->bitN; failed)
4837 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5025 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5026 this might fix SIGSEGVs on MinGW...

5471 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5472 Now 4 algorithms for mcs51 jumptable generation are used:
5473 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

5507 * added libc directory. The current version of LibC contains string
5508 functions, ctype functions and macros and some functions of the
5509 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5510 be extensively tested in the future. Standard disclaimer here.
5511 Library is not automatically build yet. But one can build it by

5524 * (genCmp): experimental code for new genCmp which uses PIC18's
5525 special compare&skip instructions. Initial tests fail some times
5526 with variables grater than 1 byte in size, so new code is disabled,
5527 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5529 * (genCast): began a fix to optimize the casting of a bit to another
5530 bit, now assigning a bitfield to another bitfield will fail, sorry,

5545 * src/pic16/ralloc.c (allocReg): add preliminary support for
5546 supporting a limited set of temporary registers,
5548 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5572 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
5574 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

8508 code / RAM are in the same page / bank. This means the linker can
8509 safely allocate code/RAM of separate ASM files to different pages/banks.
8510 * doc/sdccman.lyx: added Slade's tips

8553 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8555 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8556 loaded with the linker search paths (-L arguments) and the libraries
8557 to be linked with the current source (-l arguments). Changes
8558 currently will affect only the pic16 port.
8559 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8560 include path the port specific paths and port specific libraries,
8561 * gplink command now contains the $3 argument,
8562 * src/pic16/device.h,
8563 * src/pic16/device.c,: structure PIC_device is made public and
8564 renamed to PIC16_device, the same for variable Pics which is renamed

8579 Documenting changes from previous commits.
8580 * configure.in (version 1.56),
8581 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8582 when generating output files to configure the pic16 library,
8583 but now I've commented it out, since gputils aren't installed in the
8584 SF compile farm, so library won't compile
8586 * device/lib/Makefile.in (version 1.56): initially I've added in
8587 target 'all' the prerequestive 'model-pic16' so it compiled the
8588 pic16 library, but now I've commented it out for the same reasons
8590 * added targets 'model-pic16' and 'objects-pic16' to compile the
8592 * added target 'port-specific-objects-pic16' to handle the
8593 generated libraries and copy them into the build/ directory
8594 * added target 'clean-intermediate-pic16' to clean intermediate
8595 files into pic16 directory
8596 * in target 'installdirs' added line to create directory pic16 in
8597 the installation path
8599 * device/include/Makefile.in (version 1.11): in target 'install'
8600 added lines to copy all header files to installation path,
8601 * in target 'installdirs' added line create directory for pic16
8602 headers in the installation path

8617 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8618 option so that it actually works. Made it specific to the z80, since
8619 the gbz80 doesn't have these kinds of I/O ports.
8621 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8623 * device/include/z180.h,

8645 Mainly changes to support compilation of the device libraries
8646 * src/pic16/device.c: stack is allocated via symbol and not
8647 via literal number. The symbol is placed in the corresponding
8648 position of the data ram
8649 * (pic16_dump_section): relocatable and absolute uninitialized
8650 data are now emitted in sorted order to reduce section naming,
8651 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8652 weren't marked as being in the access bank,
8654 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8656 Added portion of GNU PIC Library under the directory
8657 device/include/pic16 and device/lib/pic16. These files
8658 contain the declarations of SFRs for the PIC18Fxx2 devices.
8659 The directory is initialized via configure from toplevel.
8661 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8663 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

8688 * doc/sdccman.lyx: Moved and added some sections, small changes
8689 all over. Telling LaTeX to be less strict with word spacing
8690 to better keep the right margin. Changed some notes about
8691 maintainance of the ports in section 3.2.1 - is it OK like this?
8693 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
8695 SDCC source changes:
8696 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

8702 processor registers declared internally by the port are emitted in
8703 the translation as equates,
8704 * src/pic16/gen.c: inline code is passed unprocessed to the

8845 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8847 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8848 (default behaviour).
8850 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8852 A python script to validate compiler diagnostic messages. It can be
8853 used to verify that sdcc complains about bad c source code and
8854 gives a good location of the error.
8855 * support/valdiag/Makefile,
8856 * support/valdiag/valdiag.py,
8857 * support/valdiag/tests/*

8872 * src/common.h: added ifndef/define/endif macros
8873 around the header file.
8874 Bug reported from Jesus Calvino-Fraga
8876 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8878 * sdcc.spec: updated
8879 * device/include/Makefile.in: don't install CVS directories
8880 * device/lib/Makefile.in: added removal of CVS directories after install
8881 * doc/Makefile: fixed install, added local_icons
8882 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8883 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8884 * src/ds390/gen.c (genRightShift): fixed bug #870788
8885 * src/SDCCast.c (decorateType): fixed bug #870781
8887 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8889 PIC16 port related changes:
8890 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8891 added variable stackPos,
8893 * gen.c: genCall, assignResultValue: added support for
8894 pushing/retrieving function parameters to/from stack,
8895 genFunction,genEndFunction: setup stack frame for the
8897 genAddrOf: will be changed according to bug 863624
8899 * added files genutils.c and genutils.h which contain gen*
8900 debugged and optimised functions extracted from gen.c
8902 * glue.c: added variable 'externs' which holds extern symbols,
8903 pic16emitRegularMap: is modified to properly handle relocatable
8904 symbols under the new scheme,
8905 pic16createInterruptVect: is modified
8906 pic16printPublics: is modified to emit 'global' assembler directives,
8907 added pic16_printExterns to print extern symbols,
8908 pic16glue: initializes stack/frame pointer in the beginning of
8909 the assembly output. Temporary hack, will be corrected later,
8910 because gplink yet does not support stack and SDCC does not
8911 yet support a type of crt0.o object to create the final binary.
8913 * Removed many lines that contain 8051 legacy code.
8914 * The code is finally placed under a 'code' directive.
8915 * Added port specific options.
8917 * _process_pragma: simplified since now we do not need *special*
8918 include file to define SFR registers. But a separate header
8919 will be needed. This will be developed later.
8920 * _pic16_parseOptions: added, parses port specific options:
8921 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8922 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8923 --preplace-udata-with=
8925 * _pic16_setDefaultOptions: modified to initialize section names,
8926 but hack is temporarly out of order since it needs improvement.
8927 * _pic16_genAssemblerPreamble: configuration words are emitted by
8928 their address instead of their name. This part is incomplete and
8929 supports only the 18Fxx2 devices. Other devices will emit an error
8930 during assembly since they do not contain the same set of config
8932 * _pic16_genIVT: is modified,
8934 * pcode.c: added definitions for some hardware registers that are needed
8936 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8937 All PCI entries are updated. Now LFSR is supported.
8938 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8939 * added pic16_newpCodeOpLit2 to support instructions with
8940 two literal arguments
8941 * pic16_pCode2str: corrected code that emits assembler instructions
8942 with two literal operands and those that have an access bit modifier
8943 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8944 this fixes a bug which caused some labels to be lost, when an
8945 assembler directive was added, i.e. banksel,
8946 * pic16_FixRegisterBanking: improved logic that causes the insertion
8948 * InlineFunction: functions that are called once, are not any more
8949 inlined. This can be a port option in the future,
8951 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8953 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8954 hold the corresponding uninitialized symbols,
8955 * pic16_allocProcessorRegister: registers have explicit marked the
8957 * pic16_allocInternalRegister: registers are explicit marked as
8959 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8960 processing list, so bit registers were lost,
8963 * ralloc.h: added field 'accessBank' and original symbol operand
8964 in register definition,
8965 * removed the field isMapped from register definition,
8967 ** Several functions have been removed from various sources:
8968 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8969 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8970 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8971 pic16_assignRelocatableRegisters
8973 ** others have been introduced:
8974 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8975 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8977 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8979 * support/scripts/inc2h.pl: changed definition of BIT_AT
8980 to emit 'sbit at' instead of 'bit at'. This was a request.
8982 PIC16 port related preliminary changes:
8983 * gen.c: prefixed function popRegFromString with
8984 pic16_ and all references to it corrected
8985 * pcode.c: all pic16_pc_* hardware registers prefixed
8986 with underscore (_),
8987 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8988 * ralloc.c: newReg(): when register is REG_SFR then
8989 set address to rIdx,
8990 pic16_allocProcessorRegister(): marks register wasUsed=0
8991 pic16_writeUsedRegs(): added a call to assign processor
8992 registers via pic16_assignFixedRegisters
8994 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8996 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8997 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8998 variables in unused register banks. Also the SSEG is placed
8999 wherever there is enough space for it, and IDATA can be anywhere
9000 in internal RAM. For now compile using -Wl-Y[stack_size].
9001 The mem file is different for this option as well, since it
9002 makes no sense of talking about DSEG lenght.
9004 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9006 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9007 in certain cases, e.g. when ROM assignment, patch provided
9008 from Albert den Haan.
9010 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9151 xdata and data memory on startup. Set the environment variable
9152 SDCC_NOGENRAMCLEAR to disable this.
9153 * src/mcs51/peephole.def,
9154 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
9155 (allows non-interrupt and interrupt code to safely compete for a resource

9916 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9918 Fixed bug #621531 (const & volatile confusion in the type chain).
9919 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
9920 refer to the const or volatile state of the pointer itself.

9997 and JUMPTABLE iCodes properly now (worked by accident before)
9998 * src/mcs51/gen.c (leftRightUseAcc),
9999 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10000 iCode properly now. Use getSize instead of nRegs since a & b
10001 aren't part of the nRegs tally.
10003 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10005 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10015 copied from genNearPointerSet()
10016 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10017 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10018 If they pop r0/r1 they must be called in the opposite order than aopOp().
10019 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10020 (resp. --stack-auto), prepared for --xstack
10022 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

10033 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10034 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10035 type for bits was changed. It resulted in bit variables becoming
10036 global, which is not permitted in PIC 14 assembly output.
10038 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10040 * doc/sdccman.lyx: various additions and updates. Rearranged sections

10053 A few small changes that speed up the peephole optimizer.
10057 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10059 Try to make the peephole optimizer smarter by maintaining
10060 an association between the assembly source code and the
10061 iCodes that originated them. Put this information to use
10062 with a new peephole rule condition "notVolatile" so that
10063 the rules can be aggressive yet still safe.
10068 * src/mcs51/peeph.def
10070 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10074 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10075 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10076 if the left or right operand symbols have the accuse flag set.
10078 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10080 Changed the type of the result of the ! (NOT) operator to char;
10081 previously it returned the same type as the source. This allows
10082 us to eliminate all the genFloatNot functions (all of its target
10083 implementations were very buggy) since !float can use the same
10086 * src/SDCCicode.c (ast2iCode): ! returns char

10095 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10096 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10097 during interrupts. Ensure WSAVE is located at a shared bank address.
10098 2. Fixed page selection in some places
10099 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10100 the registers name strings.
10101 4. Fixed "signed / unsigned compare" compiler warnings.
10102 5. The PIC port manages its own allocation of the general purpose
10103 registers, but makes no attempt to reuse them. As a result when
10104 compiling it soon runs out of general purpose registers. Some
10105 additional code was added to the files pcode.c and device.c to walk
10106 through the function call tree and rename the registers so that they
10116 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10117 genPlus() & genMinus() when the result is the same as left or right
10119 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10123 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10125 Made bitfield a distinct type from bit so that bitfields
10126 convert as per ANSI C and bits retain their traditional
10127 boolean style behaviour. Implemented bitfield support in
10135 * src/ds390/gen.c: bit v bitfield split
10136 * src/z80/gen.c: New support for bitfields
10137 * support/regression/tests/bitfields.c: reenabled z80,
10140 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10142 Rules 246.x, 247.x relate to bitfields, the others speed up
10143 access to xdata mapped I/O devices.
10145 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10147 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10149 Cleaned up genPackBits and genUnpackBits and added two helper
10150 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10151 for literal assignments in genPackBits (thanks to Frieder for
10157 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10159 Fixed bug #748310 (pointer to function type mishandled when the
10160 function name is omitted). Also fixed a SIGSEGV when a function
10161 attribute (reentrant, etc) is used on a non-function or on a
10162 function but misplaced before the parameter list.
10164 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10166 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10167 * support/Util/SDCCerr.h,
10168 * support/Util/SDCCerr.c: Added func attr misuse error msg
10170 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10172 Fixed bug #787649 by anonymous
10173 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10174 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10176 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10189 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10191 Made the constant following the "interrupt" keyword optional. If
10192 omitted, the function will not automatically be given an entry

10727 support for the PIc16 port in the ports table, when executing
10728 the compiler with no port specified on command line, a default
10729 port is selected with the new macro DEFAULT_PORT which is
10730 defined in port.h, in setDefaultOptions() linkOptions is removed
10731 from initialization assignment, since now it is a set,
10732 parseCmdLine uses setParseWithComma for linkOptions, in
10733 linkEdit() linkOptions are accessed with new function indexSet()
10734 which returns the i'th item of a set variable. See SDCCset.c, in
10735 linkEdit() when calling buildCmdLine(), added linkOptions as
10736 last argument. Now users can pass arguments to gplink via the
10737 -Wl option, main() uses pic16glue() to glue up pic16 programs
10738 * src/SDCCpeeph.c: various changes to support pic16

10751 gpasm complaining and test the linkage with gplink, _linkCmd and
10752 _asmCmd changed to be more gplink and gpasm friendly
10753 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10754 produced an error when parsed, peep rule 12 is added to utilize
10755 movff, but it is commented out since the pCode does not support
10756 yet a command with 2 address arguments

11818 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11819 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11821 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11823 * in /sdcc/as/mcs51/ changed these files in order to create an
11824 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11825 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11826 following files to include the previous two files: aslink.dsp,
11827 Makefile.aslink, Makefile.bcc, and Makefile.in.
11829 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11830 .adb instead of .cdb
11832 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11834 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11835 value from option --iram-size.
11837 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11839 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11842 2002-09-18 <wiml AT hhhh.org>
11844 * SDCClrange.h: exposed setFromRange() and setToRange()
11845 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11846 packRegsForAccUse() (bug 542397)
11847 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11848 multiple times and emitting the fetch operations more than once
11849 added aopGetUsesAcc() function to allow binary operators to
11850 fetch their operands in the correct order; made genMinus() emit
11851 compact code for X = LITERAL - Y
11853 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11854 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11855 sprintf() in line 1267.
11857 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11858 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11861 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11862 Changes to aslink (All the changes are marked with 'JCF'):
11864 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11867 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11868 area BSEG. Also moves, if possible, the DATA area down into the internal
11869 ram so more space is available.
11871 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11874 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11875 not bytes. Function summary() which creates a memory usage summary
11876 file with extension .mem. Reports of overlaping stack and small stack
11877 size. If the space for the stack is less than 16 bytes aslink trows a
11880 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11881 the 8051. Option 'y' for memory summary output file.
11883 Changes to sdcc (All the changes are marked with 'JCF'):
11885 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11887 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11888 overlaying area for it (uses RegBankUsed[4]).
11890 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11891 bank zero as used by default. By default aslink locates the stack
11892 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11893 the creation of the .mem file. Delegates the allocation of data area
11894 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11895 the begining of the stack area to aslink.
11897 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11898 glue() in SDCCglue.c creates an area for it.
11900 2002-09-03 Borut Razem <borut.razem AT siol.net>
11901 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11902 sdcc/src/pic/glue.c:
11903 introduced atexit() handler for teporay files removal in case of
11904 errors, assertions, ...
11906 2002-08-29 Borut Razem <borut.razem AT siol.net>
11907 * sdcc/support/cpp2/auto-host_vc_in.h:
11908 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11909 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11910 Maybe there is a similar problem with BORLANDC? It should be checked!
11912 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11913 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11914 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11915 was not executed, and the compiler (cl) launched a warning:
11916 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11918 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11919 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11921 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11922 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11924 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11925 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

11927 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11928 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11929 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11930 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11931 - added Release configuration in VS projects
11932 - review of compiler an linker options
11933 - VC .exe files are generated in bin_vc directory, not to interfere
11934 with binaries generated from other projects (cygwin, mingw, bcc ...)
11936 * sdcc/src/yacc.dsp: added
11938 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11939 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11940 and insert the version number definitions from .version
11942 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11944 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11945 added - genarate auto-host.h using auto-host_vc_in.h as template
11948 removed from CVS, generated automatically
11950 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11951 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11953 2002-08-11 Borut Razem <borut.razem AT siol.net>
11954 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11956 2002-08-10 Borut Razem <borut.razem AT siol.net>
11957 * src/SDCCmain.c (main):
11958 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11959 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11960 The consequence was that some temporary files were not removed.
11963 unification of code in functions tempfilename() and tempfile():
11964 function tempnam() is defined in Visual Studio 6.0 and .NET
11966 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11968 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11969 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11970 - removed compiler command line option /WX: Treats all warnings as errors
11971 - update a list of source files, included into the project
11973 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11974 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11975 changed project type to Generic Project so that can be correcly converted to VS.NET project

11990 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11991 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11992 - solved MSC error in function aopDump()

12172 Previous fix was not good. basic blocks that have "break" or "return" are
12173 not really partof a loop , but live ranges used in these blocks should

13027 * support/regression/tests/uminus.c: Added a test for the unary minus operator.
13029 * src/z80/gen.c (genUminus): Fixed add, sub, and uminus on the gbz80 port for longs. Had to shift some functions about to do it.

13050 * 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.
13052 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
13054 2001-08-29 Michael Hope <michaelh AT juju.net.nz>
