2239 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2241 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2242 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2244 One basic decision: e.g. src/clean.mk includes further files. In order
2245 to make this work there are two solutions:
2246 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2247 run configure on them. This way they can use
2248 'include $(srcdir)/port-clean.mk'
2249 - always include clean.mk by the Makefile at the same level. To avoid
2250 that `make clean` tries to include and build Makefile.dep the
2251 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2252 implemented, because now even `make uninstall` doesn't create
2253 Makefile.in. clean.mk could be eliminated by pasting it in
2256 * debugger/mcs51/Makefile.in: build own objects from library sources
2257 (SLIB, SDCC) in current directory
2259 * configure, configure.in: renamed --disable-device-lib-build in
2260 --disable-device-lib; added --enable-doc, the required tools are
2261 searched by configure; added result message; the toolchain for the
2262 belonging ports are now only built, if the port is enabled.
2264 * support/regression/*: all output is written in directory gen, because
2265 the fwk and ports directories don't livet in the build tree using vpath
2267 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2268 --disable-device-lib, added --enable-doc, added section VPATH
2270 * sim/ucsim/configure.in,
2271 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2272 z80 are enabled by default
2274 2006-04-24 Raphael Neider <rneider AT web.de>
2276 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2277 to config word, "pic14_"-prefixed some extern functions
2278 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2279 config word has been found
2280 * src/pic/device.h: added prototypes
2281 * src/pic/pcode.c: added "pic14_"-prefix where needed

2296 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
2297 registers that have not been assigned proper liveranges,
2298 fixes #1469504 and #1474602,
2299 (pCodeRegOptimizeRegUsage): fixed typo in comment

2548 (genCritical, genEndCritical): added functions
2549 (genZ80Code): added cases for CRITICAL and ENDCRITICAL

2567 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2569 * src/.version: increased version number to 2.5.5
2570 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2571 linking is done manually in pic16 port's _linkEdit,
2572 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2573 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2574 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2575 allocate asmop as AOP_ACC,
2576 (aopForRemat): added parameter 'bool result' in function declaration,

2589 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2590 call to allocReg, not by manually allocating a new one,
2591 (pic16_assignRegisters): now before going through the register
2592 allocating functions mark all registers as free. This eliminates some
2593 side effects resulting from peephole parser done earlier in the backbone
2595 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2648 made the linker quiet
2650 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2652 * src/pic16/gen.c (genPcall): fixed bug #1443644
2653 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2654 which dumps before the function entry point a data byte which represents
2655 the number of the local variables used by the specified function, added
2656 'xinst' for initial support for Extended Instruction Support,
2657 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2658 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2659 port->fun_prefix anymore (may change later),

2672 --extended or -y for Extended Instruction Support,
2673 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2674 (deassignLRs): *** perhaps the most important change, old 'for' code
2675 (commented out for reference), didn't account for some registers which
2676 were left marked 'not free' after a pointer operation. The change
2677 reduces register usage a lot in some cases

4953 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4954 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4955 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4956 always available in leading double underscore form. The C99 support is

5035 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5037 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5039 * device/lib/printf_large.c: removed inline assembly for portability and
5040 readability. Use printf_fast if speed or size are more important.
5041 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5042 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5044 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5046 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5047 prevent compiler warning
5049 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5051 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5052 moved to level 0 and declared as static. Also they are explicit
5053 placed in access bank. This was necessery because some times they
5054 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5055 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5056 optimizations. Currently only compare to unsigned char is implemented,
5057 * src/pic16/gen.c: added fReturnIdx array,
5058 * (struct resolvedIfx) is moved to gen.h and made public,
5059 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5060 * (aopForSym): added an optimization to directly store in stack of
5061 the operand of a SEND iCode,
5062 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5063 but as registers instead (AOP_REG) using the fReturnIdx array,
5064 * (pic16_freeAsmop): remove the freed register from the
5065 _G.sregsAlloc field,
5066 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5067 a compare of 'WREG',
5068 * (pic16_popGetTempRegCond): changed function prototype, now
5069 function takes also a bitVector argument v which holds the current
5070 set of registers that are allocated for stack access by aopForSym,
5071 registers allocated in aopForSym for accessing stack symbols are not
5072 any more part of the functions usedRegs field,
5073 * (genCall): some times aopOp is called for a stack variable to be
5074 send, aopForSym might perform the push, if this is true make sure
5075 that genCall doesn't push the variable twice by testing _G.resDirect,
5076 * (genFunction): changed testing for unspecified interrupt number
5077 from 256 to INTNO_UNSPEC,
5078 * modified selection scheme of frame pointer generation. Previously
5079 if function did use local registers a frame pointer was generated,
5080 now a frame pointer is generated only if function has arguments
5081 (that need PLUSW2 register access), or has stack arguments, or the
5082 compiler is not instructed to omit the frame pointer,
5083 * (genEndFunction): before restoring local registers that were saved
5084 in the function preamble, also restore the registers that *might*
5085 have been allocated for stack access,
5086 * (genRet): removed some old comments,
5087 * (genCmp, the active (RN's) version): added a call to the
5088 pic16_genCmp_special function to perform the compare with a more
5089 robust and optimized way,
5090 * (genInline): a feature has been added in inline code generation,
5091 which allows a wildcard variable substitution when writing inline
5092 assembly. Code is incomplete and experimental therefore undocumented,
5093 * (genCast): changed order of aopOp for result and right to allow
5094 aopForSym to directly load the result if possible,
5095 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5096 perform an optimized compare on some selected special occasions,
5097 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5098 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5099 generate an IVT any more,
5100 * src/pic16/main.c (pic16_optionsTable): added command line option
5102 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5103 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5105 * src/pic16/NOTES: Raphael Neider added in list of active developers
5106 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5107 jumptable_end to prevent bug #,
5108 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5109 inCond and outCond fields,
5110 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5111 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5112 turn off register spilling,
5113 * (packRegsForOneUse): synced with other ports' versions although it
5114 is not used currently,
5115 * (pic16_packRegisters): added an optimization while reading
5116 structure bitfields, some registers may be saved (malloc code is
5117 decreased by 80 bytes)
5119 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5121 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5122 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5123 this can be optimized more?
5125 2005-03-10 Raphael Neider <rneider AT web.de>
5127 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5128 genNearPointerGet): (hopefully) fixed access to bitfields via
5129 pointers (p->bitN = x; and x = p->bitN; failed)

5763 Adding support for replacing ljmps with sjmps in jumptables
5764 generated for switch statements. For now you need to set the
5765 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5766 Now 4 algorithms for mcs51 jumptable generation are used:
5767 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5768 addresses loaded pc-relative for up to 112 cases and stack-pushing
5769 target addresses loaded with offset from dptr for up to 256 cases.

5799 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5801 * added libc directory. The current version of LibC contains string
5802 functions, ctype functions and macros and some functions of the
5803 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5804 be extensively tested in the future. Standard disclaimer here.
5805 Library is not automatically build yet. But one can build it by
5806 invoking 'make' inside the libc directory.

5817 * (pic16_storeForReturn): optimized return of 0,
5818 * (genCmp): experimental code for new genCmp which uses PIC18's
5819 special compare&skip instructions. Initial tests fail some times
5820 with variables grater than 1 byte in size, so new code is disabled,
5821 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5823 * (genCast): began a fix to optimize the casting of a bit to another
5824 bit, now assigning a bitfield to another bitfield will fail, sorry,
5825 * src/pic16/main.c: disabled the use of lr-support feature,
5826 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5833 and 1 for banking instruction,
5834 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5835 caused stop processing pCodes after a inline assembly block,
5836 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5837 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5838 registers when it shouldn't,
5839 * src/pic16/ralloc.c (allocReg): add preliminary support for
5840 supporting a limited set of temporary registers,
5842 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5848 (genFunction): optimize RECEIVE iCodes in reentrant functions
5850 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5852 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8850 loaded with the linker search paths (-L arguments) and the libraries
8851 to be linked with the current source (-l arguments). Changes
8852 currently will affect only the pic16 port.
8853 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8854 include path the port specific paths and port specific libraries,
8855 * gplink command now contains the $3 argument,
8856 * src/pic16/device.h,

8873 Documenting changes from previous commits.
8874 * configure.in (version 1.56),
8875 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8876 when generating output files to configure the pic16 library,
8877 but now I've commented it out, since gputils aren't installed in the
8878 SF compile farm, so library won't compile
8880 * device/lib/Makefile.in (version 1.56): initially I've added in
8881 target 'all' the prerequestive 'model-pic16' so it compiled the
8882 pic16 library, but now I've commented it out for the same reasons
8884 * added targets 'model-pic16' and 'objects-pic16' to compile the
8886 * added target 'port-specific-objects-pic16' to handle the
8887 generated libraries and copy them into the build/ directory
8888 * added target 'clean-intermediate-pic16' to clean intermediate
8889 files into pic16 directory
8890 * in target 'installdirs' added line to create directory pic16 in

8894 added lines to copy all header files to installation path,
8895 * in target 'installdirs' added line create directory for pic16
8896 headers in the installation path

9144 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9146 A python script to validate compiler diagnostic messages. It can be
9147 used to verify that sdcc complains about bad c source code and
9148 gives a good location of the error.
9149 * support/valdiag/Makefile,
9150 * support/valdiag/valdiag.py,
9151 * support/valdiag/tests/*
9153 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9155 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
9156 * src/SDCCsymt.c (newEnumType),
9158 * support/Util/SDCCerr.c,
9159 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
9161 * support/regression/tests/enum.c: added test for enum values that
9162 require at least 2 bytes of storage.
9164 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9166 * src/common.h: added ifndef/define/endif macros
9167 around the header file.
9168 Bug reported from Jesus Calvino-Fraga
9170 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9172 * sdcc.spec: updated
9173 * device/include/Makefile.in: don't install CVS directories
9174 * device/lib/Makefile.in: added removal of CVS directories after install
9175 * doc/Makefile: fixed install, added local_icons
9176 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9177 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9178 * src/ds390/gen.c (genRightShift): fixed bug #870788
9179 * src/SDCCast.c (decorateType): fixed bug #870781
9181 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9183 PIC16 port related changes:
9184 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9185 added variable stackPos,
9187 * gen.c: genCall, assignResultValue: added support for
9188 pushing/retrieving function parameters to/from stack,
9189 genFunction,genEndFunction: setup stack frame for the
9191 genAddrOf: will be changed according to bug 863624
9193 * added files genutils.c and genutils.h which contain gen*
9194 debugged and optimised functions extracted from gen.c
9196 * glue.c: added variable 'externs' which holds extern symbols,
9197 pic16emitRegularMap: is modified to properly handle relocatable
9198 symbols under the new scheme,
9199 pic16createInterruptVect: is modified
9200 pic16printPublics: is modified to emit 'global' assembler directives,
9201 added pic16_printExterns to print extern symbols,
9202 pic16glue: initializes stack/frame pointer in the beginning of
9203 the assembly output. Temporary hack, will be corrected later,
9204 because gplink yet does not support stack and SDCC does not
9205 yet support a type of crt0.o object to create the final binary.
9207 * Removed many lines that contain 8051 legacy code.
9208 * The code is finally placed under a 'code' directive.
9209 * Added port specific options.
9211 * _process_pragma: simplified since now we do not need *special*
9212 include file to define SFR registers. But a separate header
9213 will be needed. This will be developed later.
9214 * _pic16_parseOptions: added, parses port specific options:
9215 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9216 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9217 --preplace-udata-with=
9219 * _pic16_setDefaultOptions: modified to initialize section names,
9220 but hack is temporarly out of order since it needs improvement.
9221 * _pic16_genAssemblerPreamble: configuration words are emitted by
9222 their address instead of their name. This part is incomplete and
9223 supports only the 18Fxx2 devices. Other devices will emit an error
9224 during assembly since they do not contain the same set of config
9226 * _pic16_genIVT: is modified,
9228 * pcode.c: added definitions for some hardware registers that are needed
9230 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9231 All PCI entries are updated. Now LFSR is supported.
9232 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9233 * added pic16_newpCodeOpLit2 to support instructions with
9234 two literal arguments
9235 * pic16_pCode2str: corrected code that emits assembler instructions
9236 with two literal operands and those that have an access bit modifier
9237 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9238 this fixes a bug which caused some labels to be lost, when an
9239 assembler directive was added, i.e. banksel,
9240 * pic16_FixRegisterBanking: improved logic that causes the insertion
9242 * InlineFunction: functions that are called once, are not any more
9243 inlined. This can be a port option in the future,
9245 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9247 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9248 hold the corresponding uninitialized symbols,
9249 * pic16_allocProcessorRegister: registers have explicit marked the
9251 * pic16_allocInternalRegister: registers are explicit marked as
9253 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9254 processing list, so bit registers were lost,
9257 * ralloc.h: added field 'accessBank' and original symbol operand
9258 in register definition,
9259 * removed the field isMapped from register definition,
9261 ** Several functions have been removed from various sources:
9262 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9263 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9264 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9265 pic16_assignRelocatableRegisters
9267 ** others have been introduced:
9268 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9269 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9271 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9273 * support/scripts/inc2h.pl: changed definition of BIT_AT
9274 to emit 'sbit at' instead of 'bit at'. This was a request.
9276 PIC16 port related preliminary changes:
9277 * gen.c: prefixed function popRegFromString with
9278 pic16_ and all references to it corrected
9279 * pcode.c: all pic16_pc_* hardware registers prefixed
9280 with underscore (_),
9281 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9282 * ralloc.c: newReg(): when register is REG_SFR then
9283 set address to rIdx,
9284 pic16_allocProcessorRegister(): marks register wasUsed=0
9285 pic16_writeUsedRegs(): added a call to assign processor
9286 registers via pic16_assignFixedRegisters
9288 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9290 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9291 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9292 variables in unused register banks. Also the SSEG is placed
9293 wherever there is enough space for it, and IDATA can be anywhere
9294 in internal RAM. For now compile using -Wl-Y[stack_size].
9295 The mem file is different for this option as well, since it
9296 makes no sense of talking about DSEG lenght.
9298 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9300 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9301 in certain cases, e.g. when ROM assignment, patch provided
9302 from Albert den Haan.
9304 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9447 * src/mcs51/peephole.def,
9448 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
9449 (allows non-interrupt and interrupt code to safely compete for a resource

9460 multiply defined with mismatching "at" address.
9462 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9543 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9545 * src/SDCCast.c (decorateType): disabled a transformation I added in
9546 revision 1.188 (access to fields of a structure at an absolute address);
9547 it breaks with bitfields, extern declarations, and gcse analysis.
9548 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9549 could be assigned through a pointer, so don't complain.
9550 * src/SDCCast.c (astErrors),
9552 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

10132 genCodePointerGet, genGenPointerGet, genFarPointerSet,
10133 genGenPointerSet): handle AOP_DPTR correctly when loading dptr
10134 (ralloc doesn't intentionally do this now, but perhaps later)
10135 * src/mcs51/ralloc.c (serialRegAssign, fillGaps),
10136 * src/ds390/ralloc.c (serialRegAssign, fillGaps): fixed some

10148 2003-09-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10150 * src/SDCCsymt.c (structElemType): fixed bug #808291 (members
10151 of const struct should be treated as if const themselves)
10153 2003-09-18 Bernhard Held <bernhard AT bernhardheld.de>
10155 * src/SDCCval.c (valPlus, valMinus): fixed bug #808337

10170 * src/ds390/gen.c (genFunction, genEndFunction): Moved save
10171 and restore of EA so that stack offsets to parameters are
10172 correct when using both critical and reentrant/stack-auto.
10173 * src/z80/gen.c (aopOp): removed erroneous assertion about sloc
10174 size (can be triggered in error if sloc is shared between
10175 different sized objects)
10176 * device/include/float.h: fixed macros to explicitly use
10177 unsigned long where needed
10179 2003-09-15 Bernhard Held <bernhard AT bernhardheld.de>

10185 2003-09-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10187 * src/SDCCsymt.c (sclsFromPtr),
10189 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10190 support for standard C idiom of memory mapped variables; for
10191 example, *((xdata int*)0x1234) = 1 is now internally equivalent
10192 to xdata int at 0x1234 tempvar = 1.
10193 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
10194 provided by Akiya ISHIDA

10210 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10212 Fixed bug #621531 (const & volatile confusion in the type chain).
10213 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10214 refer to the const or volatile state of the pointer itself.

10279 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
10280 pcoderegs.h, ralloc.c, ralloc.h
10281 * main.c: added top header and GPL license notice

10284 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
10286 * device/lib/_mullong.c: replaced int by short for gcc
10288 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10290 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
10291 and JUMPTABLE iCodes properly now (worked by accident before)
10292 * src/mcs51/gen.c (leftRightUseAcc),
10293 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10294 iCode properly now. Use getSize instead of nRegs since a & b
10295 aren't part of the nRegs tally.
10297 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10299 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10305 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
10306 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
10307 fetching of the pointer
10308 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
10309 copied from genNearPointerSet()
10310 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10311 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10312 If they pop r0/r1 they must be called in the opposite order than aopOp().
10313 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10314 (resp. --stack-auto), prepared for --xstack
10316 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10318 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10320 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10322 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
10323 these ports have their own __sdcc_external_start()
10325 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10327 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10328 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10329 type for bits was changed. It resulted in bit variables becoming
10330 global, which is not permitted in PIC 14 assembly output.
10332 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10334 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10336 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10338 Z80 and MCS51 linkers complaint if a public symbol is defined
10339 in more than one library module:

10345 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10347 A few small changes that speed up the peephole optimizer.
10351 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10353 Try to make the peephole optimizer smarter by maintaining
10354 an association between the assembly source code and the
10355 iCodes that originated them. Put this information to use
10356 with a new peephole rule condition "notVolatile" so that
10357 the rules can be aggressive yet still safe.
10362 * src/mcs51/peeph.def
10364 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10368 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10369 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10370 if the left or right operand symbols have the accuse flag set.
10372 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10374 Changed the type of the result of the ! (NOT) operator to char;
10375 previously it returned the same type as the source. This allows
10376 us to eliminate all the genFloatNot functions (all of its target
10377 implementations were very buggy) since !float can use the same
10380 * src/SDCCicode.c (ast2iCode): ! returns char
10381 * src/mcs51/gen.c (genNot, genNotFloat),
10382 * src/ds390/gen.c (genNot, genNotFloat),
10383 * src/z80/gen.c (genNot, genNotFloat),
10384 * src/pic/gen.c (genNot, genNotFloat),
10385 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

10389 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10390 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10391 during interrupts. Ensure WSAVE is located at a shared bank address.
10392 2. Fixed page selection in some places
10393 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10394 the registers name strings.
10395 4. Fixed "signed / unsigned compare" compiler warnings.
10396 5. The PIC port manages its own allocation of the general purpose
10397 registers, but makes no attempt to reuse them. As a result when
10398 compiling it soon runs out of general purpose registers. Some
10399 additional code was added to the files pcode.c and device.c to walk
10400 through the function call tree and rename the registers so that they
10410 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10411 genPlus() & genMinus() when the result is the same as left or right
10413 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10417 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10419 Made bitfield a distinct type from bit so that bitfields
10420 convert as per ANSI C and bits retain their traditional
10421 boolean style behaviour. Implemented bitfield support in
10429 * src/ds390/gen.c: bit v bitfield split
10430 * src/z80/gen.c: New support for bitfields
10431 * support/regression/tests/bitfields.c: reenabled z80,
10434 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10436 Rules 246.x, 247.x relate to bitfields, the others speed up
10437 access to xdata mapped I/O devices.
10439 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10441 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10443 Cleaned up genPackBits and genUnpackBits and added two helper
10444 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10445 for literal assignments in genPackBits (thanks to Frieder for
10451 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10453 Fixed bug #748310 (pointer to function type mishandled when the
10454 function name is omitted). Also fixed a SIGSEGV when a function
10455 attribute (reentrant, etc) is used on a non-function or on a
10456 function but misplaced before the parameter list.
10458 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10460 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10461 * support/Util/SDCCerr.h,
10462 * support/Util/SDCCerr.c: Added func attr misuse error msg
10464 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10466 Fixed bug #787649 by anonymous
10467 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10468 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10470 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10472 Fixed numerous bitfield problems.
10474 * src/SDCC.y: More bitfield related error checking

10477 * support/Util/SDCCerr.h,
10478 * support/Util/SDCCerr.c: Added & edited some bitfield err msgs
10479 * src/mcs51/gen.c (genPackBits, genUnpackBits): fixed mask bugs
10480 * src/ds390/gen.c (genPackBits, genUnpackBits): fixed mask bugs
10481 * support/regression/tests/bitfields.c: tests added
10483 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10485 Made the constant following the "interrupt" keyword optional. If
10486 omitted, the function will not automatically be given an entry
10487 in the interrupt vector table (similar to #pragma NOIV, but
10488 less syntacticly kludgy). The interrupt number is also now
10489 range checked. Also fixed a bug in the high order bit example

10497 * support/Util/SDCCerr.h
10500 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

10503 * src/SDCCicode.c (operandOperation): rewritten some ops
10504 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
10505 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10507 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10508 be re-activated by defining REDUCE_LITERALS)
10509 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10510 unsigned, but are signed by default
10511 * src/SDCCval.c (constVal): rearranged
10512 * src/SDCCval.c (valMod): preliminary fix
10513 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10553 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10554 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10555 constants are unsigned; added recognition of "u" flag for unsigned
10556 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10557 * src/SDCCval.c (valDiv, valMod): fixed signdness

11021 support for the PIc16 port in the ports table, when executing
11022 the compiler with no port specified on command line, a default
11023 port is selected with the new macro DEFAULT_PORT which is
11024 defined in port.h, in setDefaultOptions() linkOptions is removed
11025 from initialization assignment, since now it is a set,
11026 parseCmdLine uses setParseWithComma for linkOptions, in
11027 linkEdit() linkOptions are accessed with new function indexSet()
11028 which returns the i'th item of a set variable. See SDCCset.c, in
11029 linkEdit() when calling buildCmdLine(), added linkOptions as
11030 last argument. Now users can pass arguments to gplink via the

11045 gpasm complaining and test the linkage with gplink, _linkCmd and
11046 _asmCmd changed to be more gplink and gpasm friendly
11047 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11048 produced an error when parsed, peep rule 12 is added to utilize
11049 movff, but it is commented out since the pCode does not support
11050 yet a command with 2 address arguments

12102 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12103 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

12109 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
12110 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
12112 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12113 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12115 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12117 * in /sdcc/as/mcs51/ changed these files in order to create an
12118 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12119 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12120 following files to include the previous two files: aslink.dsp,
12121 Makefile.aslink, Makefile.bcc, and Makefile.in.
12123 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12124 .adb instead of .cdb
12126 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12128 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12129 value from option --iram-size.
12131 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12133 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12136 2002-09-18 <wiml AT hhhh.org>
12138 * SDCClrange.h: exposed setFromRange() and setToRange()
12139 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12140 packRegsForAccUse() (bug 542397)
12141 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12142 multiple times and emitting the fetch operations more than once
12143 added aopGetUsesAcc() function to allow binary operators to
12144 fetch their operands in the correct order; made genMinus() emit
12145 compact code for X = LITERAL - Y
12147 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12148 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12149 sprintf() in line 1267.
12151 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12152 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12155 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12156 Changes to aslink (All the changes are marked with 'JCF'):
12158 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12161 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12162 area BSEG. Also moves, if possible, the DATA area down into the internal
12163 ram so more space is available.
12165 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12168 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12169 not bytes. Function summary() which creates a memory usage summary
12170 file with extension .mem. Reports of overlaping stack and small stack
12171 size. If the space for the stack is less than 16 bytes aslink trows a
12174 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12175 the 8051. Option 'y' for memory summary output file.
12177 Changes to sdcc (All the changes are marked with 'JCF'):
12179 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12181 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12182 overlaying area for it (uses RegBankUsed[4]).
12184 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12185 bank zero as used by default. By default aslink locates the stack
12186 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12187 the creation of the .mem file. Delegates the allocation of data area
12188 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12189 the begining of the stack area to aslink.
12191 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12192 glue() in SDCCglue.c creates an area for it.
12194 2002-09-03 Borut Razem <borut.razem AT siol.net>
12195 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12196 sdcc/src/pic/glue.c:
12197 introduced atexit() handler for teporay files removal in case of
12198 errors, assertions, ...
12200 2002-08-29 Borut Razem <borut.razem AT siol.net>
12201 * sdcc/support/cpp2/auto-host_vc_in.h:
12202 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12203 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12204 Maybe there is a similar problem with BORLANDC? It should be checked!
12206 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12207 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12208 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12209 was not executed, and the compiler (cl) launched a warning:
12210 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12212 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12213 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12215 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12216 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12218 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12219 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12220 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12221 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12222 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12223 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12224 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12225 - added Release configuration in VS projects
12226 - review of compiler an linker options
12227 - VC .exe files are generated in bin_vc directory, not to interfere
12228 with binaries generated from other projects (cygwin, mingw, bcc ...)
12230 * sdcc/src/yacc.dsp: added
12232 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12233 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12234 and insert the version number definitions from .version
12236 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12238 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12239 added - genarate auto-host.h using auto-host_vc_in.h as template
12242 removed from CVS, generated automatically
12244 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12245 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12247 2002-08-11 Borut Razem <borut.razem AT siol.net>
12248 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12250 2002-08-10 Borut Razem <borut.razem AT siol.net>
12251 * src/SDCCmain.c (main):
12252 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12253 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12254 The consequence was that some temporary files were not removed.
12257 unification of code in functions tempfilename() and tempfile():
12258 function tempnam() is defined in Visual Studio 6.0 and .NET
12260 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12262 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12263 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12264 - removed compiler command line option /WX: Treats all warnings as errors
12265 - update a list of source files, included into the project
12267 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12268 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12269 changed project type to Generic Project so that can be correcly converted to VS.NET project
12271 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12273 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12275 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12277 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12278 added return 0 statements after assert() to make compiler happy
12280 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12281 added newline in the def file to keep MSC compiler satisfied
12283 * sdcc/src/z80/gen.c:
12284 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12285 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12286 - solved MSC error in function aopDump()
12288 * sdcc_vc.h: define PREFIX as "\\sdcc"
12290 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12291 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12294 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12295 - Rewrote the register banking algorithm.
12296 - Added pCode live-range analysis to registers (for now, only non-used and
12297 singly-used registers optimized away)
12299 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12301 * 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.

12328 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12330 2002-03-28 Johan Knol <johan AT balder>
12332 * src/SDCCval.c: fixed bug #532436
12334 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12336 Added "char *Processor" field to the port structure.
12339 Added -p option. Allows port dependent processor to be specified.
12342 Initialized the new field char *Processor field to NULL in all ports
12345 Compiler generated registers for interrupt context saving
12346 were not getting allocated.
12348 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12351 Fixed left shift. Will promote the left side of a left shift
12352 if a) left shifting more than size of operand or b) when assigned
12353 to something size > size of left side
12355 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12357 tons of changes. Register allocation has been
12358 rewritten. Added customization for the various PICs. Flow
12359 analysis is restructured. ...
12361 * src/pic/device.h:
12364 * src/pic/device.c:
12365 Added. device.c is a PIC port hack to accomodate variations
12368 2002-03-13 Michael Hope <michaelh AT vroom>
12370 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
12372 2002-03-04 johanknol <johanknol AT manik>
12374 * /src/SDCCval.c: fixed
12376 const unsigned char arr[][2] = { { 0, 1 } };
12377 t18.c:1: error: Initializer element is not constant
12379 2002-03-04 bela <bela AT manik>
