2215 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2217 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2218 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2220 One basic decision: e.g. src/clean.mk includes further files. In order
2221 to make this work there are two solutions:
2222 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2223 run configure on them. This way they can use
2224 'include $(srcdir)/port-clean.mk'
2225 - always include clean.mk by the Makefile at the same level. To avoid
2226 that `make clean` tries to include and build Makefile.dep the
2227 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2228 implemented, because now even `make uninstall` doesn't create
2229 Makefile.in. clean.mk could be eliminated by pasting it in
2232 * debugger/mcs51/Makefile.in: build own objects from library sources
2233 (SLIB, SDCC) in current directory
2235 * configure, configure.in: renamed --disable-device-lib-build in
2236 --disable-device-lib; added --enable-doc, the required tools are
2237 searched by configure; added result message; the toolchain for the
2238 belonging ports are now only built, if the port is enabled.
2240 * support/regression/*: all output is written in directory gen, because
2241 the fwk and ports directories don't livet in the build tree using vpath
2243 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2244 --disable-device-lib, added --enable-doc, added section VPATH
2246 * sim/ucsim/configure.in,
2247 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2248 z80 are enabled by default
2250 2006-04-24 Raphael Neider <rneider AT web.de>
2252 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2253 to config word, "pic14_"-prefixed some extern functions
2254 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2255 config word has been found
2256 * src/pic/device.h: added prototypes
2257 * src/pic/pcode.c: added "pic14_"-prefix where needed
2258 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2260 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2270 2006-04-24 Raphael Neider <rneider AT web.de>
2272 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
2273 registers that have not been assigned proper liveranges,
2274 fixes #1469504 and #1474602,
2275 (pCodeRegOptimizeRegUsage): fixed typo in comment
2277 2006-04-24 Borut Razem <borut.razem AT siol.net>
2279 * device/examples/main8051.c: deleted - it was removed from CVS

2548 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2549 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

2565 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2566 call to allocReg, not by manually allocating a new one,
2567 (pic16_assignRegisters): now before going through the register
2568 allocating functions mark all registers as free. This eliminates some
2569 side effects resulting from peephole parser done earlier in the backbone

2618 * src/ds390/peeph.def: disabled 186.d and 227.a as fix for #1434401
2619 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
2621 2006-03-06 Borut Razem <borut.razem AT siol.net>
2623 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2624 made the linker quiet
2626 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2628 * src/pic16/gen.c (genPcall): fixed bug #1443644
2629 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2630 which dumps before the function entry point a data byte which represents
2631 the number of the local variables used by the specified function, added
2632 'xinst' for initial support for Extended Instruction Support,
2633 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2634 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2635 port->fun_prefix anymore (may change later),
2636 (genFunction, genEndFunction): do not store/restore local registers for
2637 _main (this should take care the --main-return command line option in
2639 (genOr): removed some legacy pic-port instructions,
2640 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2641 performing operations with SFR's causes data to be written more than

2648 --extended or -y for Extended Instruction Support,
2649 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2650 (deassignLRs): *** perhaps the most important change, old 'for' code
2651 (commented out for reference), didn't account for some registers which
2652 were left marked 'not free' after a pointer operation. The change
2653 reduces register usage a lot in some cases

4926 * src/SDCCglobal.h (struct options),
4928 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4929 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4930 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4931 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4932 always available in leading double underscore form. The C99 support is
4933 mostly missing, but it's a start.
4934 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4935 reserved identifier "__data".

5013 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5015 * device/lib/printf_large.c: removed inline assembly for portability and
5016 readability. Use printf_fast if speed or size are more important.
5017 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5018 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5020 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5022 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5023 prevent compiler warning
5025 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5027 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5028 moved to level 0 and declared as static. Also they are explicit
5029 placed in access bank. This was necessery because some times they
5030 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5031 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5032 optimizations. Currently only compare to unsigned char is implemented,
5033 * src/pic16/gen.c: added fReturnIdx array,
5034 * (struct resolvedIfx) is moved to gen.h and made public,
5035 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5036 * (aopForSym): added an optimization to directly store in stack of
5037 the operand of a SEND iCode,
5038 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5039 but as registers instead (AOP_REG) using the fReturnIdx array,
5040 * (pic16_freeAsmop): remove the freed register from the
5041 _G.sregsAlloc field,
5042 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5043 a compare of 'WREG',
5044 * (pic16_popGetTempRegCond): changed function prototype, now
5045 function takes also a bitVector argument v which holds the current
5046 set of registers that are allocated for stack access by aopForSym,
5047 registers allocated in aopForSym for accessing stack symbols are not
5048 any more part of the functions usedRegs field,
5049 * (genCall): some times aopOp is called for a stack variable to be
5050 send, aopForSym might perform the push, if this is true make sure
5051 that genCall doesn't push the variable twice by testing _G.resDirect,
5052 * (genFunction): changed testing for unspecified interrupt number
5053 from 256 to INTNO_UNSPEC,
5054 * modified selection scheme of frame pointer generation. Previously
5055 if function did use local registers a frame pointer was generated,
5056 now a frame pointer is generated only if function has arguments
5057 (that need PLUSW2 register access), or has stack arguments, or the
5058 compiler is not instructed to omit the frame pointer,
5059 * (genEndFunction): before restoring local registers that were saved
5060 in the function preamble, also restore the registers that *might*
5061 have been allocated for stack access,
5062 * (genRet): removed some old comments,
5063 * (genCmp, the active (RN's) version): added a call to the
5064 pic16_genCmp_special function to perform the compare with a more
5065 robust and optimized way,
5066 * (genInline): a feature has been added in inline code generation,
5067 which allows a wildcard variable substitution when writing inline
5068 assembly. Code is incomplete and experimental therefore undocumented,
5069 * (genCast): changed order of aopOp for result and right to allow
5070 aopForSym to directly load the result if possible,
5071 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5072 perform an optimized compare on some selected special occasions,
5073 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5074 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5075 generate an IVT any more,
5076 * src/pic16/main.c (pic16_optionsTable): added command line option
5078 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5079 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5081 * src/pic16/NOTES: Raphael Neider added in list of active developers
5082 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5083 jumptable_end to prevent bug #,
5084 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5085 inCond and outCond fields,
5086 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5087 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5088 turn off register spilling,
5089 * (packRegsForOneUse): synced with other ports' versions although it
5090 is not used currently,
5091 * (pic16_packRegisters): added an optimization while reading
5092 structure bitfields, some registers may be saved (malloc code is
5093 decreased by 80 bytes)
5095 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5097 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5098 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5099 this can be optimized more?
5101 2005-03-10 Raphael Neider <rneider AT web.de>
5103 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5104 genNearPointerGet): (hopefully) fixed access to bitfields via
5105 pointers (p->bitN = x; and x = p->bitN; failed)
5107 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
5109 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

5739 Adding support for replacing ljmps with sjmps in jumptables
5740 generated for switch statements. For now you need to set the
5741 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5742 Now 4 algorithms for mcs51 jumptable generation are used:
5743 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5744 addresses loaded pc-relative for up to 112 cases and stack-pushing
5745 target addresses loaded with offset from dptr for up to 256 cases.

5775 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5777 * added libc directory. The current version of LibC contains string
5778 functions, ctype functions and macros and some functions of the
5779 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5780 be extensively tested in the future. Standard disclaimer here.
5781 Library is not automatically build yet. But one can build it by
5782 invoking 'make' inside the libc directory.

5793 * (pic16_storeForReturn): optimized return of 0,
5794 * (genCmp): experimental code for new genCmp which uses PIC18's
5795 special compare&skip instructions. Initial tests fail some times
5796 with variables grater than 1 byte in size, so new code is disabled,
5797 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5799 * (genCast): began a fix to optimize the casting of a bit to another
5800 bit, now assigning a bitfield to another bitfield will fail, sorry,
5801 * src/pic16/main.c: disabled the use of lr-support feature,
5802 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5809 and 1 for banking instruction,
5810 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5811 caused stop processing pCodes after a inline assembly block,
5812 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5813 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5814 registers when it shouldn't,
5815 * src/pic16/ralloc.c (allocReg): add preliminary support for
5816 supporting a limited set of temporary registers,
5818 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5820 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5821 genDataPointerSet): ensure assignments always copy in MSB to LSB
5823 (loadRegFromAop): recognize CLRH optimization,
5824 (genFunction): optimize RECEIVE iCodes in reentrant functions
5826 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5828 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8826 loaded with the linker search paths (-L arguments) and the libraries
8827 to be linked with the current source (-l arguments). Changes
8828 currently will affect only the pic16 port.
8829 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8830 include path the port specific paths and port specific libraries,
8831 * gplink command now contains the $3 argument,
8832 * src/pic16/device.h,

8849 Documenting changes from previous commits.
8850 * configure.in (version 1.56),
8851 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8852 when generating output files to configure the pic16 library,
8853 but now I've commented it out, since gputils aren't installed in the
8854 SF compile farm, so library won't compile
8856 * device/lib/Makefile.in (version 1.56): initially I've added in
8857 target 'all' the prerequestive 'model-pic16' so it compiled the
8858 pic16 library, but now I've commented it out for the same reasons
8860 * added targets 'model-pic16' and 'objects-pic16' to compile the
8862 * added target 'port-specific-objects-pic16' to handle the
8863 generated libraries and copy them into the build/ directory
8864 * added target 'clean-intermediate-pic16' to clean intermediate
8865 files into pic16 directory
8866 * in target 'installdirs' added line to create directory pic16 in

9149 * device/include/Makefile.in: don't install CVS directories
9150 * device/lib/Makefile.in: added removal of CVS directories after install
9151 * doc/Makefile: fixed install, added local_icons
9152 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9153 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9154 * src/ds390/gen.c (genRightShift): fixed bug #870788
9155 * src/SDCCast.c (decorateType): fixed bug #870781
9157 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9159 PIC16 port related changes:
9160 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9161 added variable stackPos,
9163 * gen.c: genCall, assignResultValue: added support for
9164 pushing/retrieving function parameters to/from stack,
9165 genFunction,genEndFunction: setup stack frame for the
9167 genAddrOf: will be changed according to bug 863624
9169 * added files genutils.c and genutils.h which contain gen*
9170 debugged and optimised functions extracted from gen.c
9172 * glue.c: added variable 'externs' which holds extern symbols,
9173 pic16emitRegularMap: is modified to properly handle relocatable
9174 symbols under the new scheme,
9175 pic16createInterruptVect: is modified
9176 pic16printPublics: is modified to emit 'global' assembler directives,
9177 added pic16_printExterns to print extern symbols,
9178 pic16glue: initializes stack/frame pointer in the beginning of
9179 the assembly output. Temporary hack, will be corrected later,
9180 because gplink yet does not support stack and SDCC does not
9181 yet support a type of crt0.o object to create the final binary.
9183 * Removed many lines that contain 8051 legacy code.
9184 * The code is finally placed under a 'code' directive.
9185 * Added port specific options.
9187 * _process_pragma: simplified since now we do not need *special*
9188 include file to define SFR registers. But a separate header
9189 will be needed. This will be developed later.
9190 * _pic16_parseOptions: added, parses port specific options:
9191 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9192 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9193 --preplace-udata-with=
9195 * _pic16_setDefaultOptions: modified to initialize section names,
9196 but hack is temporarly out of order since it needs improvement.
9197 * _pic16_genAssemblerPreamble: configuration words are emitted by
9198 their address instead of their name. This part is incomplete and
9199 supports only the 18Fxx2 devices. Other devices will emit an error
9200 during assembly since they do not contain the same set of config
9202 * _pic16_genIVT: is modified,
9204 * pcode.c: added definitions for some hardware registers that are needed
9206 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9207 All PCI entries are updated. Now LFSR is supported.
9208 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9209 * added pic16_newpCodeOpLit2 to support instructions with
9210 two literal arguments
9211 * pic16_pCode2str: corrected code that emits assembler instructions
9212 with two literal operands and those that have an access bit modifier
9213 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9214 this fixes a bug which caused some labels to be lost, when an
9215 assembler directive was added, i.e. banksel,
9216 * pic16_FixRegisterBanking: improved logic that causes the insertion
9218 * InlineFunction: functions that are called once, are not any more
9219 inlined. This can be a port option in the future,
9221 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9223 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9224 hold the corresponding uninitialized symbols,
9225 * pic16_allocProcessorRegister: registers have explicit marked the
9227 * pic16_allocInternalRegister: registers are explicit marked as
9229 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9230 processing list, so bit registers were lost,
9233 * ralloc.h: added field 'accessBank' and original symbol operand
9234 in register definition,
9235 * removed the field isMapped from register definition,
9237 ** Several functions have been removed from various sources:
9238 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9239 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9240 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9241 pic16_assignRelocatableRegisters
9243 ** others have been introduced:
9244 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9245 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9247 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9249 * support/scripts/inc2h.pl: changed definition of BIT_AT
9250 to emit 'sbit at' instead of 'bit at'. This was a request.
9252 PIC16 port related preliminary changes:
9253 * gen.c: prefixed function popRegFromString with
9254 pic16_ and all references to it corrected
9255 * pcode.c: all pic16_pc_* hardware registers prefixed
9256 with underscore (_),
9257 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9258 * ralloc.c: newReg(): when register is REG_SFR then
9259 set address to rIdx,
9260 pic16_allocProcessorRegister(): marks register wasUsed=0
9261 pic16_writeUsedRegs(): added a call to assign processor
9262 registers via pic16_assignFixedRegisters
9264 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9266 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9267 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9268 variables in unused register banks. Also the SSEG is placed
9269 wherever there is enough space for it, and IDATA can be anywhere
9270 in internal RAM. For now compile using -Wl-Y[stack_size].
9271 The mem file is different for this option as well, since it
9272 makes no sense of talking about DSEG lenght.
9274 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9276 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9277 in certain cases, e.g. when ROM assignment, patch provided
9278 from Albert den Haan.

9519 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9521 * src/SDCCast.c (decorateType): disabled a transformation I added in
9522 revision 1.188 (access to fields of a structure at an absolute address);
9523 it breaks with bitfields, extern declarations, and gcse analysis.
9524 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9525 could be assigned through a pointer, so don't complain.
9526 * src/SDCCast.c (astErrors),
9528 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

10126 * src/SDCCsymt.c (structElemType): fixed bug #808291 (members
10127 of const struct should be treated as if const themselves)
10129 2003-09-18 Bernhard Held <bernhard AT bernhardheld.de>
10131 * src/SDCCval.c (valPlus, valMinus): fixed bug #808337

10146 * src/ds390/gen.c (genFunction, genEndFunction): Moved save
10147 and restore of EA so that stack offsets to parameters are
10148 correct when using both critical and reentrant/stack-auto.

10163 * src/SDCCsymt.c (sclsFromPtr),
10165 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10166 support for standard C idiom of memory mapped variables; for
10167 example, *((xdata int*)0x1234) = 1 is now internally equivalent
10168 to xdata int at 0x1234 tempvar = 1.
10169 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch

10186 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10188 Fixed bug #621531 (const & volatile confusion in the type chain).
10189 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10190 refer to the const or volatile state of the pointer itself.

10255 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
10256 pcoderegs.h, ralloc.c, ralloc.h
10257 * main.c: added top header and GPL license notice
10258 * pcode.c: fixed the if-conditional warning
10260 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
10262 * device/lib/_mullong.c: replaced int by short for gcc
10264 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10266 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
10267 and JUMPTABLE iCodes properly now (worked by accident before)
10268 * src/mcs51/gen.c (leftRightUseAcc),
10269 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10270 iCode properly now. Use getSize instead of nRegs since a & b
10271 aren't part of the nRegs tally.
10273 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10275 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10281 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
10282 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
10283 fetching of the pointer
10284 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
10285 copied from genNearPointerSet()
10286 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10287 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10288 If they pop r0/r1 they must be called in the opposite order than aopOp().
10289 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10290 (resp. --stack-auto), prepared for --xstack
10292 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10294 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10296 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>

10299 these ports have their own __sdcc_external_start()
10301 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10303 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10304 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10305 type for bits was changed. It resulted in bit variables becoming
10306 global, which is not permitted in PIC 14 assembly output.
10308 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10310 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10312 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10314 Z80 and MCS51 linkers complaint if a public symbol is defined
10315 in more than one library module:

10321 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10323 A few small changes that speed up the peephole optimizer.
10327 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10329 Try to make the peephole optimizer smarter by maintaining
10330 an association between the assembly source code and the
10331 iCodes that originated them. Put this information to use
10332 with a new peephole rule condition "notVolatile" so that
10333 the rules can be aggressive yet still safe.
10338 * src/mcs51/peeph.def
10340 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10344 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10345 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10346 if the left or right operand symbols have the accuse flag set.
10348 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10350 Changed the type of the result of the ! (NOT) operator to char;
10351 previously it returned the same type as the source. This allows
10352 us to eliminate all the genFloatNot functions (all of its target
10353 implementations were very buggy) since !float can use the same
10356 * src/SDCCicode.c (ast2iCode): ! returns char
10357 * src/mcs51/gen.c (genNot, genNotFloat),
10358 * src/ds390/gen.c (genNot, genNotFloat),
10359 * src/z80/gen.c (genNot, genNotFloat),
10360 * src/pic/gen.c (genNot, genNotFloat),

10365 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10366 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10367 during interrupts. Ensure WSAVE is located at a shared bank address.
10368 2. Fixed page selection in some places
10369 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10370 the registers name strings.
10371 4. Fixed "signed / unsigned compare" compiler warnings.
10372 5. The PIC port manages its own allocation of the general purpose
10373 registers, but makes no attempt to reuse them. As a result when
10374 compiling it soon runs out of general purpose registers. Some
10375 additional code was added to the files pcode.c and device.c to walk
10376 through the function call tree and rename the registers so that they
10386 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10387 genPlus() & genMinus() when the result is the same as left or right
10389 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10393 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10395 Made bitfield a distinct type from bit so that bitfields
10396 convert as per ANSI C and bits retain their traditional
10397 boolean style behaviour. Implemented bitfield support in
10405 * src/ds390/gen.c: bit v bitfield split
10406 * src/z80/gen.c: New support for bitfields
10407 * support/regression/tests/bitfields.c: reenabled z80,
10410 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10412 Rules 246.x, 247.x relate to bitfields, the others speed up
10413 access to xdata mapped I/O devices.
10415 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10417 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10419 Cleaned up genPackBits and genUnpackBits and added two helper
10420 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10421 for literal assignments in genPackBits (thanks to Frieder for
10427 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10429 Fixed bug #748310 (pointer to function type mishandled when the
10430 function name is omitted). Also fixed a SIGSEGV when a function
10431 attribute (reentrant, etc) is used on a non-function or on a
10432 function but misplaced before the parameter list.
10434 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10436 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10437 * support/Util/SDCCerr.h,
10438 * support/Util/SDCCerr.c: Added func attr misuse error msg
10440 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10442 Fixed bug #787649 by anonymous
10443 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10444 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10446 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10448 Fixed numerous bitfield problems.
10450 * src/SDCC.y: More bitfield related error checking

10457 * support/regression/tests/bitfields.c: tests added
10459 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10461 Made the constant following the "interrupt" keyword optional. If
10462 omitted, the function will not automatically be given an entry
10463 in the interrupt vector table (similar to #pragma NOIV, but
10464 less syntacticly kludgy). The interrupt number is also now
10465 range checked. Also fixed a bug in the high order bit example

10473 * support/Util/SDCCerr.h
10476 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

10479 * src/SDCCicode.c (operandOperation): rewritten some ops
10480 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
10481 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10483 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10484 be re-activated by defining REDUCE_LITERALS)
10485 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10486 unsigned, but are signed by default
10487 * src/SDCCval.c (constVal): rearranged
10488 * src/SDCCval.c (valMod): preliminary fix
10489 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10529 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10530 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10531 constants are unsigned; added recognition of "u" flag for unsigned
10532 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10533 * src/SDCCval.c (valDiv, valMod): fixed signdness
10534 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
10535 signedness of modulo, left and right shift

10997 support for the PIc16 port in the ports table, when executing
10998 the compiler with no port specified on command line, a default
10999 port is selected with the new macro DEFAULT_PORT which is
11000 defined in port.h, in setDefaultOptions() linkOptions is removed
11001 from initialization assignment, since now it is a set,
11002 parseCmdLine uses setParseWithComma for linkOptions, in
11003 linkEdit() linkOptions are accessed with new function indexSet()
11004 which returns the i'th item of a set variable. See SDCCset.c, in
11005 linkEdit() when calling buildCmdLine(), added linkOptions as
11006 last argument. Now users can pass arguments to gplink via the
11007 -Wl option, main() uses pic16glue() to glue up pic16 programs

11021 gpasm complaining and test the linkage with gplink, _linkCmd and
11022 _asmCmd changed to be more gplink and gpasm friendly
11023 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11024 produced an error when parsed, peep rule 12 is added to utilize
11025 movff, but it is commented out since the pCode does not support
11026 yet a command with 2 address arguments

12088 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12089 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12091 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12093 * in /sdcc/as/mcs51/ changed these files in order to create an
12094 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12095 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12096 following files to include the previous two files: aslink.dsp,
12097 Makefile.aslink, Makefile.bcc, and Makefile.in.
12099 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12100 .adb instead of .cdb
12102 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12104 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12105 value from option --iram-size.
12107 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12109 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12112 2002-09-18 <wiml AT hhhh.org>
12114 * SDCClrange.h: exposed setFromRange() and setToRange()
12115 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12116 packRegsForAccUse() (bug 542397)
12117 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12118 multiple times and emitting the fetch operations more than once
12119 added aopGetUsesAcc() function to allow binary operators to
12120 fetch their operands in the correct order; made genMinus() emit
12121 compact code for X = LITERAL - Y
12123 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12124 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12125 sprintf() in line 1267.
12127 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12128 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12131 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12132 Changes to aslink (All the changes are marked with 'JCF'):
12134 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12137 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12138 area BSEG. Also moves, if possible, the DATA area down into the internal
12139 ram so more space is available.
12141 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12144 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12145 not bytes. Function summary() which creates a memory usage summary
12146 file with extension .mem. Reports of overlaping stack and small stack
12147 size. If the space for the stack is less than 16 bytes aslink trows a
12150 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12151 the 8051. Option 'y' for memory summary output file.
12153 Changes to sdcc (All the changes are marked with 'JCF'):
12155 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12157 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12158 overlaying area for it (uses RegBankUsed[4]).
12160 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12161 bank zero as used by default. By default aslink locates the stack
12162 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12163 the creation of the .mem file. Delegates the allocation of data area
12164 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12165 the begining of the stack area to aslink.
12167 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12168 glue() in SDCCglue.c creates an area for it.
12170 2002-09-03 Borut Razem <borut.razem AT siol.net>
12171 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12172 sdcc/src/pic/glue.c:
12173 introduced atexit() handler for teporay files removal in case of
12174 errors, assertions, ...
12176 2002-08-29 Borut Razem <borut.razem AT siol.net>
12177 * sdcc/support/cpp2/auto-host_vc_in.h:
12178 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12179 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12180 Maybe there is a similar problem with BORLANDC? It should be checked!
12182 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12183 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12184 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12185 was not executed, and the compiler (cl) launched a warning:
12186 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12188 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12189 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12191 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12192 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12194 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12195 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12196 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12197 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12198 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12199 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12200 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12201 - added Release configuration in VS projects
12202 - review of compiler an linker options
12203 - VC .exe files are generated in bin_vc directory, not to interfere
12204 with binaries generated from other projects (cygwin, mingw, bcc ...)
12206 * sdcc/src/yacc.dsp: added
12208 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12209 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12210 and insert the version number definitions from .version
12212 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12214 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12215 added - genarate auto-host.h using auto-host_vc_in.h as template
12218 removed from CVS, generated automatically
12220 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12221 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12223 2002-08-11 Borut Razem <borut.razem AT siol.net>
12224 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12226 2002-08-10 Borut Razem <borut.razem AT siol.net>
12227 * src/SDCCmain.c (main):
12228 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12229 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12230 The consequence was that some temporary files were not removed.
12233 unification of code in functions tempfilename() and tempfile():
12234 function tempnam() is defined in Visual Studio 6.0 and .NET
12236 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12238 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12239 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12240 - removed compiler command line option /WX: Treats all warnings as errors
12241 - update a list of source files, included into the project
12243 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12244 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12245 changed project type to Generic Project so that can be correcly converted to VS.NET project
12247 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12249 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12251 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12253 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12254 added return 0 statements after assert() to make compiler happy
12256 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12257 added newline in the def file to keep MSC compiler satisfied
12259 * sdcc/src/z80/gen.c:
12260 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12261 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12262 - solved MSC error in function aopDump()
12264 * sdcc_vc.h: define PREFIX as "\\sdcc"
12266 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12267 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12270 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12271 - Rewrote the register banking algorithm.
12272 - Added pCode live-range analysis to registers (for now, only non-used and
12273 singly-used registers optimized away)
12275 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12277 * 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.

12306 2002-03-28 Johan Knol <johan AT balder>
12308 * src/SDCCval.c: fixed bug #532436
12310 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12312 Added "char *Processor" field to the port structure.
12315 Added -p option. Allows port dependent processor to be specified.
12318 Initialized the new field char *Processor field to NULL in all ports
12321 Compiler generated registers for interrupt context saving
12322 were not getting allocated.
12324 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12327 Fixed left shift. Will promote the left side of a left shift
12328 if a) left shifting more than size of operand or b) when assigned
12329 to something size > size of left side
12331 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12333 tons of changes. Register allocation has been
12334 rewritten. Added customization for the various PICs. Flow
12335 analysis is restructured. ...
12337 * src/pic/device.h:
12340 * src/pic/device.c:
12341 Added. device.c is a PIC port hack to accomodate variations

12346 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
12348 2002-03-04 johanknol <johanknol AT manik>
12350 * /src/SDCCval.c: fixed
12352 const unsigned char arr[][2] = { { 0, 1 } };

12441 * sdcc/src/SDCCloop.c:
12442 Previous fix was not good. basic blocks that have "break" or "return" are
12443 not really partof a loop , but live ranges used in these blocks should
12444 be live thru the entire loop, so set partOfLoop but don't add them to
