1902 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1904 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1905 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1907 One basic decision: e.g. src/clean.mk includes further files. In order
1908 to make this work there are two solutions:
1909 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1910 run configure on them. This way they can use
1911 'include $(srcdir)/port-clean.mk'
1912 - always include clean.mk by the Makefile at the same level. To avoid
1913 that `make clean` tries to include and build Makefile.dep the
1914 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1915 implemented, because now even `make uninstall` doesn't create
1916 Makefile.in. clean.mk could be eliminated by pasting it in
1919 * debugger/mcs51/Makefile.in: build own objects from library sources
1920 (SLIB, SDCC) in current directory
1922 * configure, configure.in: renamed --disable-device-lib-build in
1923 --disable-device-lib; added --enable-doc, the required tools are
1924 searched by configure; added result message; the toolchain for the
1925 belonging ports are now only built, if the port is enabled.
1927 * support/regression/*: all output is written in directory gen, because
1928 the fwk and ports directories don't livet in the build tree using vpath
1930 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1931 --disable-device-lib, added --enable-doc, added section VPATH
1933 * sim/ucsim/configure.in,
1934 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1935 z80 are enabled by default
1937 2006-04-24 Raphael Neider <rneider AT web.de>
1939 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1940 to config word, "pic14_"-prefixed some extern functions
1941 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1942 config word has been found
1943 * src/pic/device.h: added prototypes
1944 * src/pic/pcode.c: added "pic14_"-prefix where needed

2185 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
2187 * src/mcs51/gen.c (genCall): fixed bug 1457608
2189 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2191 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest
2192 changes seem to cause (trigger?) problems with the build system.
2194 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
2196 * src/SDCCpeeph.c (operandsLiteral): new, added,
2197 (callFuncByName): inserted operandsLiteral

2207 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
2208 implemented patch 1120823 Thanks to Willy De la Court (normal
2209 interrupts need an interrupt number now if they are made critical),
2210 and enabled nesting of critical functions though not for gbz80
2211 (genCritical, genEndCritical): added functions
2212 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2213 * src/z80/mappings.i: added "ei" to all mappings
2215 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2217 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
2218 submitted by the Debian SDCC maintainer Aurelien Jarno:
2219 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
2220 archive with gcc 4.1 on mips and wrote the patch"
2222 2006-03-16 Raphael Neider <rneider AT web.de>
2224 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
2225 the left operand is shorter than the result (c* = lit-c* + int),
2227 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2230 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2232 * src/.version: increased version number to 2.5.5
2233 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2234 linking is done manually in pic16 port's _linkEdit,
2235 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2236 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2237 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2238 allocate asmop as AOP_ACC,
2239 (aopForRemat): added parameter 'bool result' in function declaration,
2240 (pic16_aopGet): return AOP_ACC when accessing WREG,
2241 (pic16_popGetTempReg): minor modification,
2242 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2243 'pic16_allocWithIdx',
2244 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
2245 calling function in absolute addresses,
2246 (genAssign): take into account AOP_ACC asmop,
2247 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
2248 * src/pic16/pcoderegs.c: some debug functions and lines added,
2249 * src/pic16/ralloc.c (decodeRegType): added but commented out,
2250 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2252 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2253 call to allocReg, not by manually allocating a new one,
2254 (pic16_assignRegisters): now before going through the register
2255 allocating functions mark all registers as free. This eliminates some
2256 side effects resulting from peephole parser done earlier in the backbone
2258 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
2260 * src/SDCCicode.c (geniCodeLogic),

2279 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
2280 (aopForSym, aopOp): increment asmop.allocated if reused,
2281 (freeAsmop): decrement asmop.allocated and check for zero instead of
2283 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2284 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
2285 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

2308 2006-03-06 Borut Razem <borut.razem AT siol.net>
2310 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2311 made the linker quiet
2313 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2315 * src/pic16/gen.c (genPcall): fixed bug #1443644
2316 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2317 which dumps before the function entry point a data byte which represents
2318 the number of the local variables used by the specified function, added
2319 'xinst' for initial support for Extended Instruction Support,
2320 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2321 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2322 port->fun_prefix anymore (may change later),
2323 (genFunction, genEndFunction): do not store/restore local registers for
2324 _main (this should take care the --main-return command line option in
2326 (genOr): removed some legacy pic-port instructions,
2327 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2328 performing operations with SFR's causes data to be written more than
2329 once to each SFR. Perhaps SFRs should be handled in special cases...
2330 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2332 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2333 into account for stack starting position,
2334 (struct OPTIONS pic16_optionsTable): added command line argument
2335 --extended or -y for Extended Instruction Support,
2336 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2337 (deassignLRs): *** perhaps the most important change, old 'for' code
2338 (commented out for reference), didn't account for some registers which
2339 were left marked 'not free' after a pointer operation. The change
2340 reduces register usage a lot in some cases
2342 2006-03-04 Borut Razem <borut.razem AT siol.net>

4721 * (struct resolvedIfx) is moved to gen.h and made public,
4722 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4723 * (aopForSym): added an optimization to directly store in stack of
4724 the operand of a SEND iCode,
4725 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4726 but as registers instead (AOP_REG) using the fReturnIdx array,
4727 * (pic16_freeAsmop): remove the freed register from the
4728 _G.sregsAlloc field,
4729 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4730 a compare of 'WREG',
4731 * (pic16_popGetTempRegCond): changed function prototype, now
4732 function takes also a bitVector argument v which holds the current
4733 set of registers that are allocated for stack access by aopForSym,
4734 registers allocated in aopForSym for accessing stack symbols are not
4735 any more part of the functions usedRegs field,
4736 * (genCall): some times aopOp is called for a stack variable to be
4737 send, aopForSym might perform the push, if this is true make sure
4738 that genCall doesn't push the variable twice by testing _G.resDirect,
4739 * (genFunction): changed testing for unspecified interrupt number
4740 from 256 to INTNO_UNSPEC,
4741 * modified selection scheme of frame pointer generation. Previously
4742 if function did use local registers a frame pointer was generated,
4743 now a frame pointer is generated only if function has arguments
4744 (that need PLUSW2 register access), or has stack arguments, or the
4745 compiler is not instructed to omit the frame pointer,
4746 * (genEndFunction): before restoring local registers that were saved
4747 in the function preamble, also restore the registers that *might*
4748 have been allocated for stack access,
4749 * (genRet): removed some old comments,
4750 * (genCmp, the active (RN's) version): added a call to the
4751 pic16_genCmp_special function to perform the compare with a more
4752 robust and optimized way,
4753 * (genInline): a feature has been added in inline code generation,
4754 which allows a wildcard variable substitution when writing inline
4755 assembly. Code is incomplete and experimental therefore undocumented,
4756 * (genCast): changed order of aopOp for result and right to allow
4757 aopForSym to directly load the result if possible,
4758 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4759 perform an optimized compare on some selected special occasions,
4760 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4761 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4762 generate an IVT any more,
4763 * src/pic16/main.c (pic16_optionsTable): added command line option
4765 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4766 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4768 * src/pic16/NOTES: Raphael Neider added in list of active developers
4769 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4770 jumptable_end to prevent bug #,
4771 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4772 inCond and outCond fields,
4773 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4774 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4775 turn off register spilling,
4776 * (packRegsForOneUse): synced with other ports' versions although it
4777 is not used currently,
4778 * (pic16_packRegisters): added an optimization while reading
4779 structure bitfields, some registers may be saved (malloc code is
4780 decreased by 80 bytes)
4782 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4784 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4785 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4786 this can be optimized more?
4788 2005-03-10 Raphael Neider <rneider AT web.de>
4790 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4791 genNearPointerGet): (hopefully) fixed access to bitfields via
4792 pointers (p->bitN = x; and x = p->bitN; failed)

5118 access stack and frame pointers. They are initially assigned to
5119 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
5120 accessing SFRs. Updated all occurences of modification of stack or
5121 frame pointer in gen.c and pcode.c,

5426 Adding support for replacing ljmps with sjmps in jumptables
5427 generated for switch statements. For now you need to set the
5428 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5429 Now 4 algorithms for mcs51 jumptable generation are used:
5430 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5431 addresses loaded pc-relative for up to 112 cases and stack-pushing

5464 * added libc directory. The current version of LibC contains string
5465 functions, ctype functions and macros and some functions of the
5466 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5467 be extensively tested in the future. Standard disclaimer here.

5481 * (genCmp): experimental code for new genCmp which uses PIC18's
5482 special compare&skip instructions. Initial tests fail some times
5483 with variables grater than 1 byte in size, so new code is disabled,
5484 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5486 * (genCast): began a fix to optimize the casting of a bit to another
5487 bit, now assigning a bitfield to another bitfield will fail, sorry,

8513 loaded with the linker search paths (-L arguments) and the libraries
8514 to be linked with the current source (-l arguments). Changes
8515 currently will affect only the pic16 port.
8516 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8517 include path the port specific paths and port specific libraries,
8518 * gplink command now contains the $3 argument,
8519 * src/pic16/device.h,
8520 * src/pic16/device.c,: structure PIC_device is made public and
8521 renamed to PIC16_device, the same for variable Pics which is renamed

8536 Documenting changes from previous commits.
8537 * configure.in (version 1.56),
8538 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8539 when generating output files to configure the pic16 library,
8540 but now I've commented it out, since gputils aren't installed in the
8541 SF compile farm, so library won't compile
8543 * device/lib/Makefile.in (version 1.56): initially I've added in
8544 target 'all' the prerequestive 'model-pic16' so it compiled the
8545 pic16 library, but now I've commented it out for the same reasons
8547 * added targets 'model-pic16' and 'objects-pic16' to compile the
8549 * added target 'port-specific-objects-pic16' to handle the
8550 generated libraries and copy them into the build/ directory
8551 * added target 'clean-intermediate-pic16' to clean intermediate
8552 files into pic16 directory
8553 * in target 'installdirs' added line to create directory pic16 in

8802 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8804 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8805 (default behaviour).
8807 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8809 A python script to validate compiler diagnostic messages. It can be
8810 used to verify that sdcc complains about bad c source code and
8811 gives a good location of the error.
8812 * support/valdiag/Makefile,
8813 * support/valdiag/valdiag.py,
8814 * support/valdiag/tests/*

8831 Bug reported from Jesus Calvino-Fraga
8833 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8835 * sdcc.spec: updated
8836 * device/include/Makefile.in: don't install CVS directories
8837 * device/lib/Makefile.in: added removal of CVS directories after install
8838 * doc/Makefile: fixed install, added local_icons
8839 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8840 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8841 * src/ds390/gen.c (genRightShift): fixed bug #870788
8842 * src/SDCCast.c (decorateType): fixed bug #870781
8844 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8846 PIC16 port related changes:
8847 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8848 added variable stackPos,
8850 * gen.c: genCall, assignResultValue: added support for
8851 pushing/retrieving function parameters to/from stack,
8852 genFunction,genEndFunction: setup stack frame for the
8854 genAddrOf: will be changed according to bug 863624
8856 * added files genutils.c and genutils.h which contain gen*
8857 debugged and optimised functions extracted from gen.c
8859 * glue.c: added variable 'externs' which holds extern symbols,
8860 pic16emitRegularMap: is modified to properly handle relocatable
8861 symbols under the new scheme,
8862 pic16createInterruptVect: is modified
8863 pic16printPublics: is modified to emit 'global' assembler directives,
8864 added pic16_printExterns to print extern symbols,
8865 pic16glue: initializes stack/frame pointer in the beginning of
8866 the assembly output. Temporary hack, will be corrected later,
8867 because gplink yet does not support stack and SDCC does not
8868 yet support a type of crt0.o object to create the final binary.
8870 * Removed many lines that contain 8051 legacy code.
8871 * The code is finally placed under a 'code' directive.
8872 * Added port specific options.
8874 * _process_pragma: simplified since now we do not need *special*
8875 include file to define SFR registers. But a separate header
8876 will be needed. This will be developed later.
8877 * _pic16_parseOptions: added, parses port specific options:
8878 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8879 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8880 --preplace-udata-with=
8882 * _pic16_setDefaultOptions: modified to initialize section names,
8883 but hack is temporarly out of order since it needs improvement.
8884 * _pic16_genAssemblerPreamble: configuration words are emitted by
8885 their address instead of their name. This part is incomplete and
8886 supports only the 18Fxx2 devices. Other devices will emit an error
8887 during assembly since they do not contain the same set of config
8889 * _pic16_genIVT: is modified,
8891 * pcode.c: added definitions for some hardware registers that are needed
8893 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8894 All PCI entries are updated. Now LFSR is supported.
8895 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8896 * added pic16_newpCodeOpLit2 to support instructions with
8897 two literal arguments
8898 * pic16_pCode2str: corrected code that emits assembler instructions
8899 with two literal operands and those that have an access bit modifier
8900 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8901 this fixes a bug which caused some labels to be lost, when an
8902 assembler directive was added, i.e. banksel,
8903 * pic16_FixRegisterBanking: improved logic that causes the insertion
8905 * InlineFunction: functions that are called once, are not any more
8906 inlined. This can be a port option in the future,
8908 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8910 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8911 hold the corresponding uninitialized symbols,
8912 * pic16_allocProcessorRegister: registers have explicit marked the
8914 * pic16_allocInternalRegister: registers are explicit marked as
8916 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8917 processing list, so bit registers were lost,
8920 * ralloc.h: added field 'accessBank' and original symbol operand
8921 in register definition,
8922 * removed the field isMapped from register definition,
8924 ** Several functions have been removed from various sources:
8925 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8926 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8927 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8928 pic16_assignRelocatableRegisters
8930 ** others have been introduced:
8931 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8932 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8934 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8936 * support/scripts/inc2h.pl: changed definition of BIT_AT
8937 to emit 'sbit at' instead of 'bit at'. This was a request.
8939 PIC16 port related preliminary changes:
8940 * gen.c: prefixed function popRegFromString with
8941 pic16_ and all references to it corrected
8942 * pcode.c: all pic16_pc_* hardware registers prefixed
8943 with underscore (_),
8944 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8945 * ralloc.c: newReg(): when register is REG_SFR then
8946 set address to rIdx,
8947 pic16_allocProcessorRegister(): marks register wasUsed=0
8948 pic16_writeUsedRegs(): added a call to assign processor
8949 registers via pic16_assignFixedRegisters
8951 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8953 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8954 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8955 variables in unused register banks. Also the SSEG is placed
8956 wherever there is enough space for it, and IDATA can be anywhere
8957 in internal RAM. For now compile using -Wl-Y[stack_size].
8958 The mem file is different for this option as well, since it
8959 makes no sense of talking about DSEG lenght.
8961 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8963 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8964 in certain cases, e.g. when ROM assignment, patch provided
8965 from Albert den Haan.
8967 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9873 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9875 Fixed bug #621531 (const & volatile confusion in the type chain).
9876 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
9877 refer to the const or volatile state of the pointer itself.

9955 * src/mcs51/gen.c (leftRightUseAcc),
9956 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
9957 iCode properly now. Use getSize instead of nRegs since a & b
9958 aren't part of the nRegs tally.

9972 copied from genNearPointerSet()
9973 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9974 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9975 If they pop r0/r1 they must be called in the opposite order than aopOp().
9976 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9977 (resp. --stack-auto), prepared for --xstack
9979 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9988 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9990 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9991 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9992 type for bits was changed. It resulted in bit variables becoming
9993 global, which is not permitted in PIC 14 assembly output.
9995 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9997 * doc/sdccman.lyx: various additions and updates. Rearranged sections

10008 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10010 A few small changes that speed up the peephole optimizer.
10014 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10016 Try to make the peephole optimizer smarter by maintaining
10017 an association between the assembly source code and the
10018 iCodes that originated them. Put this information to use
10019 with a new peephole rule condition "notVolatile" so that
10020 the rules can be aggressive yet still safe.
10025 * src/mcs51/peeph.def
10027 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10031 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10032 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10033 if the left or right operand symbols have the accuse flag set.
10035 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10037 Changed the type of the result of the ! (NOT) operator to char;
10038 previously it returned the same type as the source. This allows
10039 us to eliminate all the genFloatNot functions (all of its target
10040 implementations were very buggy) since !float can use the same
10043 * src/SDCCicode.c (ast2iCode): ! returns char
10044 * src/mcs51/gen.c (genNot, genNotFloat),
10045 * src/ds390/gen.c (genNot, genNotFloat),

10052 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10053 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10054 during interrupts. Ensure WSAVE is located at a shared bank address.
10055 2. Fixed page selection in some places
10056 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10057 the registers name strings.
10058 4. Fixed "signed / unsigned compare" compiler warnings.
10059 5. The PIC port manages its own allocation of the general purpose
10060 registers, but makes no attempt to reuse them. As a result when
10061 compiling it soon runs out of general purpose registers. Some
10062 additional code was added to the files pcode.c and device.c to walk
10063 through the function call tree and rename the registers so that they
10073 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10074 genPlus() & genMinus() when the result is the same as left or right
10076 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10080 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10082 Made bitfield a distinct type from bit so that bitfields
10083 convert as per ANSI C and bits retain their traditional
10084 boolean style behaviour. Implemented bitfield support in
10092 * src/ds390/gen.c: bit v bitfield split
10093 * src/z80/gen.c: New support for bitfields
10094 * support/regression/tests/bitfields.c: reenabled z80,
10097 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10099 Rules 246.x, 247.x relate to bitfields, the others speed up
10100 access to xdata mapped I/O devices.
10102 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10104 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10106 Cleaned up genPackBits and genUnpackBits and added two helper
10107 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10108 for literal assignments in genPackBits (thanks to Frieder for
10114 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10116 Fixed bug #748310 (pointer to function type mishandled when the
10117 function name is omitted). Also fixed a SIGSEGV when a function
10118 attribute (reentrant, etc) is used on a non-function or on a
10119 function but misplaced before the parameter list.
10121 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10123 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10124 * support/Util/SDCCerr.h,
10125 * support/Util/SDCCerr.c: Added func attr misuse error msg
10127 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10129 Fixed bug #787649 by anonymous
10130 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10131 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10133 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10146 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10148 Made the constant following the "interrupt" keyword optional. If
10149 omitted, the function will not automatically be given an entry
10150 in the interrupt vector table (similar to #pragma NOIV, but
10151 less syntacticly kludgy). The interrupt number is also now
10152 range checked. Also fixed a bug in the high order bit example

10168 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10170 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10171 be re-activated by defining REDUCE_LITERALS)
10172 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10173 unsigned, but are signed by default
10174 * src/SDCCval.c (constVal): rearranged
10175 * src/SDCCval.c (valMod): preliminary fix
10176 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10216 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10217 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10218 constants are unsigned; added recognition of "u" flag for unsigned
10219 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10220 * src/SDCCval.c (valDiv, valMod): fixed signdness

10682 added if/endif conditional macros to remove options help
10683 messages from optionsTable when a port is not configured, added
10684 support for the PIc16 port in the ports table, when executing
10685 the compiler with no port specified on command line, a default
10686 port is selected with the new macro DEFAULT_PORT which is
10687 defined in port.h, in setDefaultOptions() linkOptions is removed
10688 from initialization assignment, since now it is a set,
10689 parseCmdLine uses setParseWithComma for linkOptions, in
10690 linkEdit() linkOptions are accessed with new function indexSet()
10691 which returns the i'th item of a set variable. See SDCCset.c, in
10692 linkEdit() when calling buildCmdLine(), added linkOptions as
10693 last argument. Now users can pass arguments to gplink via the
10694 -Wl option, main() uses pic16glue() to glue up pic16 programs

10708 gpasm complaining and test the linkage with gplink, _linkCmd and
10709 _asmCmd changed to be more gplink and gpasm friendly
10710 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10711 produced an error when parsed, peep rule 12 is added to utilize
10712 movff, but it is commented out since the pCode does not support
10713 yet a command with 2 address arguments
10715 2003-05-18 <johan AT balder>
10717 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11765 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11766 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11772 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11773 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11775 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11776 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11778 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11780 * in /sdcc/as/mcs51/ changed these files in order to create an
11781 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11782 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11783 following files to include the previous two files: aslink.dsp,
11784 Makefile.aslink, Makefile.bcc, and Makefile.in.
11786 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11787 .adb instead of .cdb
11789 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11791 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11792 value from option --iram-size.
11794 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11796 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11799 2002-09-18 <wiml AT hhhh.org>
11801 * SDCClrange.h: exposed setFromRange() and setToRange()
11802 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11803 packRegsForAccUse() (bug 542397)
11804 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11805 multiple times and emitting the fetch operations more than once
11806 added aopGetUsesAcc() function to allow binary operators to
11807 fetch their operands in the correct order; made genMinus() emit
11808 compact code for X = LITERAL - Y
11810 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11811 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11812 sprintf() in line 1267.
11814 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11815 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11818 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11819 Changes to aslink (All the changes are marked with 'JCF'):
11821 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11824 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11825 area BSEG. Also moves, if possible, the DATA area down into the internal
11826 ram so more space is available.
11828 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11831 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11832 not bytes. Function summary() which creates a memory usage summary
11833 file with extension .mem. Reports of overlaping stack and small stack
11834 size. If the space for the stack is less than 16 bytes aslink trows a
11837 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11838 the 8051. Option 'y' for memory summary output file.
11840 Changes to sdcc (All the changes are marked with 'JCF'):
11842 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11844 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11845 overlaying area for it (uses RegBankUsed[4]).
11847 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11848 bank zero as used by default. By default aslink locates the stack
11849 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11850 the creation of the .mem file. Delegates the allocation of data area
11851 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11852 the begining of the stack area to aslink.
11854 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11855 glue() in SDCCglue.c creates an area for it.
11857 2002-09-03 Borut Razem <borut.razem AT siol.net>
11858 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11859 sdcc/src/pic/glue.c:
11860 introduced atexit() handler for teporay files removal in case of
11861 errors, assertions, ...
11863 2002-08-29 Borut Razem <borut.razem AT siol.net>
11864 * sdcc/support/cpp2/auto-host_vc_in.h:
11865 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11866 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11867 Maybe there is a similar problem with BORLANDC? It should be checked!
11869 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11870 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11871 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11872 was not executed, and the compiler (cl) launched a warning:
11873 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11875 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11876 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11878 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11879 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11881 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11882 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11883 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11884 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11885 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11886 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11887 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11888 - added Release configuration in VS projects
11889 - review of compiler an linker options
11890 - VC .exe files are generated in bin_vc directory, not to interfere
11891 with binaries generated from other projects (cygwin, mingw, bcc ...)
11893 * sdcc/src/yacc.dsp: added
11895 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11896 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11897 and insert the version number definitions from .version
11899 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11901 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11902 added - genarate auto-host.h using auto-host_vc_in.h as template
11905 removed from CVS, generated automatically
11907 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11908 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11910 2002-08-11 Borut Razem <borut.razem AT siol.net>
11911 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11913 2002-08-10 Borut Razem <borut.razem AT siol.net>
11914 * src/SDCCmain.c (main):
11915 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11916 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11917 The consequence was that some temporary files were not removed.
11920 unification of code in functions tempfilename() and tempfile():
11921 function tempnam() is defined in Visual Studio 6.0 and .NET
11923 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11925 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11926 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11927 - removed compiler command line option /WX: Treats all warnings as errors
11928 - update a list of source files, included into the project
11930 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11931 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11932 changed project type to Generic Project so that can be correcly converted to VS.NET project
11934 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11936 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11938 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11940 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11941 added return 0 statements after assert() to make compiler happy
11943 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11944 added newline in the def file to keep MSC compiler satisfied
11946 * sdcc/src/z80/gen.c:
11947 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11948 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11949 - solved MSC error in function aopDump()
11951 * sdcc_vc.h: define PREFIX as "\\sdcc"
11953 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11954 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11956 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11957 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11958 - Rewrote the register banking algorithm.
11959 - Added pCode live-range analysis to registers (for now, only non-used and
11960 singly-used registers optimized away)
11962 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11964 * 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.
11966 2002-05-10 Scott Dattalo <scott AT dattalo.com>
11967 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
