2224 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2226 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2227 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2229 One basic decision: e.g. src/clean.mk includes further files. In order
2230 to make this work there are two solutions:
2231 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2232 run configure on them. This way they can use
2233 'include $(srcdir)/port-clean.mk'
2234 - always include clean.mk by the Makefile at the same level. To avoid
2235 that `make clean` tries to include and build Makefile.dep the
2236 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2237 implemented, because now even `make uninstall` doesn't create
2238 Makefile.in. clean.mk could be eliminated by pasting it in
2241 * debugger/mcs51/Makefile.in: build own objects from library sources
2242 (SLIB, SDCC) in current directory
2244 * configure, configure.in: renamed --disable-device-lib-build in
2245 --disable-device-lib; added --enable-doc, the required tools are
2246 searched by configure; added result message; the toolchain for the
2247 belonging ports are now only built, if the port is enabled.
2249 * support/regression/*: all output is written in directory gen, because
2250 the fwk and ports directories don't livet in the build tree using vpath
2252 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2253 --disable-device-lib, added --enable-doc, added section VPATH
2255 * sim/ucsim/configure.in,
2256 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2257 z80 are enabled by default
2259 2006-04-24 Raphael Neider <rneider AT web.de>
2261 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2262 to config word, "pic14_"-prefixed some extern functions
2263 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2264 config word has been found
2265 * src/pic/device.h: added prototypes
2266 * src/pic/pcode.c: added "pic14_"-prefix where needed
2267 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2269 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2281 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
2282 registers that have not been assigned proper liveranges,
2283 fixes #1469504 and #1474602,
2284 (pCodeRegOptimizeRegUsage): fixed typo in comment

2288 * device/examples/main8051.c: deleted - it was removed from CVS

2557 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2558 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

2574 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2575 call to allocReg, not by manually allocating a new one,
2576 (pic16_assignRegisters): now before going through the register
2577 allocating functions mark all registers as free. This eliminates some
2578 side effects resulting from peephole parser done earlier in the backbone
2580 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2603 (freeAsmop): decrement asmop.allocated and check for zero instead of
2605 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2606 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

2628 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
2630 2006-03-06 Borut Razem <borut.razem AT siol.net>
2632 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2633 made the linker quiet
2635 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2637 * src/pic16/gen.c (genPcall): fixed bug #1443644
2638 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2639 which dumps before the function entry point a data byte which represents
2640 the number of the local variables used by the specified function, added
2641 'xinst' for initial support for Extended Instruction Support,
2642 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2643 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2644 port->fun_prefix anymore (may change later),
2645 (genFunction, genEndFunction): do not store/restore local registers for
2646 _main (this should take care the --main-return command line option in
2648 (genOr): removed some legacy pic-port instructions,
2649 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2650 performing operations with SFR's causes data to be written more than

2657 --extended or -y for Extended Instruction Support,
2658 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2659 (deassignLRs): *** perhaps the most important change, old 'for' code
2660 (commented out for reference), didn't account for some registers which
2661 were left marked 'not free' after a pointer operation. The change
2662 reduces register usage a lot in some cases

4937 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4938 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4939 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4940 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4941 always available in leading double underscore form. The C99 support is
4942 mostly missing, but it's a start.
4943 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4944 reserved identifier "__data".
4946 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

5020 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5022 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5024 * device/lib/printf_large.c: removed inline assembly for portability and
5025 readability. Use printf_fast if speed or size are more important.
5026 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5027 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5029 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5031 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5032 prevent compiler warning
5034 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5036 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5037 moved to level 0 and declared as static. Also they are explicit
5038 placed in access bank. This was necessery because some times they
5039 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5040 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5041 optimizations. Currently only compare to unsigned char is implemented,
5042 * src/pic16/gen.c: added fReturnIdx array,
5043 * (struct resolvedIfx) is moved to gen.h and made public,
5044 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5045 * (aopForSym): added an optimization to directly store in stack of
5046 the operand of a SEND iCode,
5047 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5048 but as registers instead (AOP_REG) using the fReturnIdx array,
5049 * (pic16_freeAsmop): remove the freed register from the
5050 _G.sregsAlloc field,
5051 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5052 a compare of 'WREG',
5053 * (pic16_popGetTempRegCond): changed function prototype, now
5054 function takes also a bitVector argument v which holds the current
5055 set of registers that are allocated for stack access by aopForSym,
5056 registers allocated in aopForSym for accessing stack symbols are not
5057 any more part of the functions usedRegs field,
5058 * (genCall): some times aopOp is called for a stack variable to be
5059 send, aopForSym might perform the push, if this is true make sure
5060 that genCall doesn't push the variable twice by testing _G.resDirect,
5061 * (genFunction): changed testing for unspecified interrupt number
5062 from 256 to INTNO_UNSPEC,
5063 * modified selection scheme of frame pointer generation. Previously
5064 if function did use local registers a frame pointer was generated,
5065 now a frame pointer is generated only if function has arguments
5066 (that need PLUSW2 register access), or has stack arguments, or the
5067 compiler is not instructed to omit the frame pointer,
5068 * (genEndFunction): before restoring local registers that were saved
5069 in the function preamble, also restore the registers that *might*
5070 have been allocated for stack access,
5071 * (genRet): removed some old comments,
5072 * (genCmp, the active (RN's) version): added a call to the
5073 pic16_genCmp_special function to perform the compare with a more
5074 robust and optimized way,
5075 * (genInline): a feature has been added in inline code generation,
5076 which allows a wildcard variable substitution when writing inline
5077 assembly. Code is incomplete and experimental therefore undocumented,
5078 * (genCast): changed order of aopOp for result and right to allow
5079 aopForSym to directly load the result if possible,
5080 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5081 perform an optimized compare on some selected special occasions,
5082 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5083 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5084 generate an IVT any more,
5085 * src/pic16/main.c (pic16_optionsTable): added command line option
5087 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5088 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5090 * src/pic16/NOTES: Raphael Neider added in list of active developers
5091 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5092 jumptable_end to prevent bug #,
5093 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5094 inCond and outCond fields,
5095 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5096 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5097 turn off register spilling,
5098 * (packRegsForOneUse): synced with other ports' versions although it
5099 is not used currently,
5100 * (pic16_packRegisters): added an optimization while reading
5101 structure bitfields, some registers may be saved (malloc code is
5102 decreased by 80 bytes)
5104 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5106 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5107 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5108 this can be optimized more?
5110 2005-03-10 Raphael Neider <rneider AT web.de>
5112 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5113 genNearPointerGet): (hopefully) fixed access to bitfields via
5114 pointers (p->bitN = x; and x = p->bitN; failed)
5116 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
5118 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
5120 2005-03-09 Raphael Neider <rneider AT web.de>

5124 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
5126 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC
5127 * src/mcs51/ralloc.c (willCauseSpill): added check for REG_BIT type,
5128 (regTypeNum): set REG_BIT type if necessary
5129 * src/mcs51/ralloc.h: added define REG_BIT, used to fix bug 1144613

5748 Adding support for replacing ljmps with sjmps in jumptables
5749 generated for switch statements. For now you need to set the
5750 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5751 Now 4 algorithms for mcs51 jumptable generation are used:
5752 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5753 addresses loaded pc-relative for up to 112 cases and stack-pushing
5754 target addresses loaded with offset from dptr for up to 256 cases.

5784 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5786 * added libc directory. The current version of LibC contains string
5787 functions, ctype functions and macros and some functions of the
5788 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5789 be extensively tested in the future. Standard disclaimer here.
5790 Library is not automatically build yet. But one can build it by
5791 invoking 'make' inside the libc directory.

5802 * (pic16_storeForReturn): optimized return of 0,
5803 * (genCmp): experimental code for new genCmp which uses PIC18's
5804 special compare&skip instructions. Initial tests fail some times
5805 with variables grater than 1 byte in size, so new code is disabled,
5806 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5808 * (genCast): began a fix to optimize the casting of a bit to another
5809 bit, now assigning a bitfield to another bitfield will fail, sorry,
5810 * src/pic16/main.c: disabled the use of lr-support feature,
5811 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5817 * (isBankInstruction): modified to return 0 for no banking instruction,
5818 and 1 for banking instruction,
5819 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5820 caused stop processing pCodes after a inline assembly block,
5821 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5822 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5823 registers when it shouldn't,
5824 * src/pic16/ralloc.c (allocReg): add preliminary support for
5825 supporting a limited set of temporary registers,
5827 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5829 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5830 genDataPointerSet): ensure assignments always copy in MSB to LSB
5832 (loadRegFromAop): recognize CLRH optimization,
5833 (genFunction): optimize RECEIVE iCodes in reentrant functions
5835 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5837 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8835 loaded with the linker search paths (-L arguments) and the libraries
8836 to be linked with the current source (-l arguments). Changes
8837 currently will affect only the pic16 port.
8838 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8839 include path the port specific paths and port specific libraries,
8840 * gplink command now contains the $3 argument,
8841 * src/pic16/device.h,
8842 * src/pic16/device.c,: structure PIC_device is made public and

8858 Documenting changes from previous commits.
8859 * configure.in (version 1.56),
8860 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8861 when generating output files to configure the pic16 library,
8862 but now I've commented it out, since gputils aren't installed in the
8863 SF compile farm, so library won't compile
8865 * device/lib/Makefile.in (version 1.56): initially I've added in
8866 target 'all' the prerequestive 'model-pic16' so it compiled the
8867 pic16 library, but now I've commented it out for the same reasons
8869 * added targets 'model-pic16' and 'objects-pic16' to compile the
8871 * added target 'port-specific-objects-pic16' to handle the
8872 generated libraries and copy them into the build/ directory
8873 * added target 'clean-intermediate-pic16' to clean intermediate
8874 files into pic16 directory
8875 * in target 'installdirs' added line to create directory pic16 in

9141 * src/SDCCsymt.c (newEnumType),
9143 * support/Util/SDCCerr.c,
9144 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
9146 * support/regression/tests/enum.c: added test for enum values that
9147 require at least 2 bytes of storage.
9149 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9151 * src/common.h: added ifndef/define/endif macros
9152 around the header file.
9153 Bug reported from Jesus Calvino-Fraga
9155 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9157 * sdcc.spec: updated
9158 * device/include/Makefile.in: don't install CVS directories
9159 * device/lib/Makefile.in: added removal of CVS directories after install
9160 * doc/Makefile: fixed install, added local_icons
9161 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9162 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9163 * src/ds390/gen.c (genRightShift): fixed bug #870788
9164 * src/SDCCast.c (decorateType): fixed bug #870781
9166 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9168 PIC16 port related changes:
9169 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9170 added variable stackPos,
9172 * gen.c: genCall, assignResultValue: added support for
9173 pushing/retrieving function parameters to/from stack,
9174 genFunction,genEndFunction: setup stack frame for the
9176 genAddrOf: will be changed according to bug 863624
9178 * added files genutils.c and genutils.h which contain gen*
9179 debugged and optimised functions extracted from gen.c
9181 * glue.c: added variable 'externs' which holds extern symbols,
9182 pic16emitRegularMap: is modified to properly handle relocatable
9183 symbols under the new scheme,
9184 pic16createInterruptVect: is modified
9185 pic16printPublics: is modified to emit 'global' assembler directives,
9186 added pic16_printExterns to print extern symbols,
9187 pic16glue: initializes stack/frame pointer in the beginning of
9188 the assembly output. Temporary hack, will be corrected later,
9189 because gplink yet does not support stack and SDCC does not
9190 yet support a type of crt0.o object to create the final binary.
9192 * Removed many lines that contain 8051 legacy code.
9193 * The code is finally placed under a 'code' directive.
9194 * Added port specific options.
9196 * _process_pragma: simplified since now we do not need *special*
9197 include file to define SFR registers. But a separate header
9198 will be needed. This will be developed later.
9199 * _pic16_parseOptions: added, parses port specific options:
9200 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9201 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9202 --preplace-udata-with=
9204 * _pic16_setDefaultOptions: modified to initialize section names,
9205 but hack is temporarly out of order since it needs improvement.
9206 * _pic16_genAssemblerPreamble: configuration words are emitted by
9207 their address instead of their name. This part is incomplete and
9208 supports only the 18Fxx2 devices. Other devices will emit an error
9209 during assembly since they do not contain the same set of config
9211 * _pic16_genIVT: is modified,
9213 * pcode.c: added definitions for some hardware registers that are needed
9215 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9216 All PCI entries are updated. Now LFSR is supported.
9217 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9218 * added pic16_newpCodeOpLit2 to support instructions with
9219 two literal arguments
9220 * pic16_pCode2str: corrected code that emits assembler instructions
9221 with two literal operands and those that have an access bit modifier
9222 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9223 this fixes a bug which caused some labels to be lost, when an
9224 assembler directive was added, i.e. banksel,
9225 * pic16_FixRegisterBanking: improved logic that causes the insertion
9227 * InlineFunction: functions that are called once, are not any more
9228 inlined. This can be a port option in the future,
9230 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9232 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9233 hold the corresponding uninitialized symbols,
9234 * pic16_allocProcessorRegister: registers have explicit marked the
9236 * pic16_allocInternalRegister: registers are explicit marked as
9238 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9239 processing list, so bit registers were lost,
9242 * ralloc.h: added field 'accessBank' and original symbol operand
9243 in register definition,
9244 * removed the field isMapped from register definition,
9246 ** Several functions have been removed from various sources:
9247 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9248 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9249 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9250 pic16_assignRelocatableRegisters
9252 ** others have been introduced:
9253 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9254 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9256 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9258 * support/scripts/inc2h.pl: changed definition of BIT_AT
9259 to emit 'sbit at' instead of 'bit at'. This was a request.
9261 PIC16 port related preliminary changes:
9262 * gen.c: prefixed function popRegFromString with
9263 pic16_ and all references to it corrected
9264 * pcode.c: all pic16_pc_* hardware registers prefixed
9265 with underscore (_),
9266 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9267 * ralloc.c: newReg(): when register is REG_SFR then
9268 set address to rIdx,
9269 pic16_allocProcessorRegister(): marks register wasUsed=0
9270 pic16_writeUsedRegs(): added a call to assign processor
9271 registers via pic16_assignFixedRegisters
9273 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9275 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9276 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9277 variables in unused register banks. Also the SSEG is placed
9278 wherever there is enough space for it, and IDATA can be anywhere
9279 in internal RAM. For now compile using -Wl-Y[stack_size].
9280 The mem file is different for this option as well, since it
9281 makes no sense of talking about DSEG lenght.
9283 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9285 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9286 in certain cases, e.g. when ROM assignment, patch provided
9287 from Albert den Haan.

9432 * src/mcs51/peephole.def,
9433 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

9528 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9530 * src/SDCCast.c (decorateType): disabled a transformation I added in
9531 revision 1.188 (access to fields of a structure at an absolute address);
9532 it breaks with bitfields, extern declarations, and gcse analysis.
9533 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9534 could be assigned through a pointer, so don't complain.
9535 * src/SDCCast.c (astErrors),
9537 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

10155 * src/ds390/gen.c (genFunction, genEndFunction): Moved save
10156 and restore of EA so that stack offsets to parameters are
10157 correct when using both critical and reentrant/stack-auto.

10172 * src/SDCCsymt.c (sclsFromPtr),
10174 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10175 support for standard C idiom of memory mapped variables; for
10176 example, *((xdata int*)0x1234) = 1 is now internally equivalent
10177 to xdata int at 0x1234 tempvar = 1.

10195 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10197 Fixed bug #621531 (const & volatile confusion in the type chain).
10198 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10199 refer to the const or volatile state of the pointer itself.

10269 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
10271 * device/lib/_mullong.c: replaced int by short for gcc
10273 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10275 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
10276 and JUMPTABLE iCodes properly now (worked by accident before)
10277 * src/mcs51/gen.c (leftRightUseAcc),
10278 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10279 iCode properly now. Use getSize instead of nRegs since a & b
10280 aren't part of the nRegs tally.
10282 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10284 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10294 copied from genNearPointerSet()
10295 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10296 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10297 If they pop r0/r1 they must be called in the opposite order than aopOp().
10298 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10299 (resp. --stack-auto), prepared for --xstack
10301 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10303 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10305 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>

10310 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10312 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10313 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10314 type for bits was changed. It resulted in bit variables becoming
10315 global, which is not permitted in PIC 14 assembly output.
10317 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10319 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10321 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10323 Z80 and MCS51 linkers complaint if a public symbol is defined
10324 in more than one library module:

10330 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10332 A few small changes that speed up the peephole optimizer.
10336 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10338 Try to make the peephole optimizer smarter by maintaining
10339 an association between the assembly source code and the
10340 iCodes that originated them. Put this information to use
10341 with a new peephole rule condition "notVolatile" so that
10342 the rules can be aggressive yet still safe.
10347 * src/mcs51/peeph.def
10349 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10353 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10354 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10355 if the left or right operand symbols have the accuse flag set.
10357 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10359 Changed the type of the result of the ! (NOT) operator to char;
10360 previously it returned the same type as the source. This allows
10361 us to eliminate all the genFloatNot functions (all of its target
10362 implementations were very buggy) since !float can use the same
10365 * src/SDCCicode.c (ast2iCode): ! returns char

10374 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10375 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10376 during interrupts. Ensure WSAVE is located at a shared bank address.
10377 2. Fixed page selection in some places
10378 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10379 the registers name strings.
10380 4. Fixed "signed / unsigned compare" compiler warnings.
10381 5. The PIC port manages its own allocation of the general purpose
10382 registers, but makes no attempt to reuse them. As a result when
10383 compiling it soon runs out of general purpose registers. Some
10384 additional code was added to the files pcode.c and device.c to walk
10385 through the function call tree and rename the registers so that they
10395 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10396 genPlus() & genMinus() when the result is the same as left or right
10398 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10402 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10404 Made bitfield a distinct type from bit so that bitfields
10405 convert as per ANSI C and bits retain their traditional
10406 boolean style behaviour. Implemented bitfield support in
10414 * src/ds390/gen.c: bit v bitfield split
10415 * src/z80/gen.c: New support for bitfields
10416 * support/regression/tests/bitfields.c: reenabled z80,
10419 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10421 Rules 246.x, 247.x relate to bitfields, the others speed up
10422 access to xdata mapped I/O devices.
10424 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10426 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10428 Cleaned up genPackBits and genUnpackBits and added two helper
10429 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10430 for literal assignments in genPackBits (thanks to Frieder for
10436 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10438 Fixed bug #748310 (pointer to function type mishandled when the
10439 function name is omitted). Also fixed a SIGSEGV when a function
10440 attribute (reentrant, etc) is used on a non-function or on a
10441 function but misplaced before the parameter list.
10443 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10445 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10446 * support/Util/SDCCerr.h,
10447 * support/Util/SDCCerr.c: Added func attr misuse error msg
10449 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10451 Fixed bug #787649 by anonymous
10452 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10453 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10455 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10457 Fixed numerous bitfield problems.
10459 * src/SDCC.y: More bitfield related error checking

10468 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10470 Made the constant following the "interrupt" keyword optional. If
10471 omitted, the function will not automatically be given an entry
10472 in the interrupt vector table (similar to #pragma NOIV, but
10473 less syntacticly kludgy). The interrupt number is also now
10474 range checked. Also fixed a bug in the high order bit example

10482 * support/Util/SDCCerr.h
10485 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

10488 * src/SDCCicode.c (operandOperation): rewritten some ops
10489 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
10490 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10492 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10493 be re-activated by defining REDUCE_LITERALS)
10494 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10495 unsigned, but are signed by default
10496 * src/SDCCval.c (constVal): rearranged
10497 * src/SDCCval.c (valMod): preliminary fix
10498 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10538 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10539 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10540 constants are unsigned; added recognition of "u" flag for unsigned
10541 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10542 * src/SDCCval.c (valDiv, valMod): fixed signdness

11006 support for the PIc16 port in the ports table, when executing
11007 the compiler with no port specified on command line, a default
11008 port is selected with the new macro DEFAULT_PORT which is
11009 defined in port.h, in setDefaultOptions() linkOptions is removed
11010 from initialization assignment, since now it is a set,
11011 parseCmdLine uses setParseWithComma for linkOptions, in
11012 linkEdit() linkOptions are accessed with new function indexSet()
11013 which returns the i'th item of a set variable. See SDCCset.c, in
11014 linkEdit() when calling buildCmdLine(), added linkOptions as
11015 last argument. Now users can pass arguments to gplink via the

11030 gpasm complaining and test the linkage with gplink, _linkCmd and
11031 _asmCmd changed to be more gplink and gpasm friendly
11032 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11033 produced an error when parsed, peep rule 12 is added to utilize
11034 movff, but it is commented out since the pCode does not support
11035 yet a command with 2 address arguments

12097 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12098 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12100 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12102 * in /sdcc/as/mcs51/ changed these files in order to create an
12103 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12104 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12105 following files to include the previous two files: aslink.dsp,
12106 Makefile.aslink, Makefile.bcc, and Makefile.in.
12108 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12109 .adb instead of .cdb
12111 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12113 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12114 value from option --iram-size.
12116 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12118 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12121 2002-09-18 <wiml AT hhhh.org>
12123 * SDCClrange.h: exposed setFromRange() and setToRange()
12124 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12125 packRegsForAccUse() (bug 542397)
12126 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12127 multiple times and emitting the fetch operations more than once
12128 added aopGetUsesAcc() function to allow binary operators to
12129 fetch their operands in the correct order; made genMinus() emit
12130 compact code for X = LITERAL - Y
12132 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12133 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12134 sprintf() in line 1267.
12136 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12137 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12140 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12141 Changes to aslink (All the changes are marked with 'JCF'):
12143 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12146 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12147 area BSEG. Also moves, if possible, the DATA area down into the internal
12148 ram so more space is available.
12150 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12153 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12154 not bytes. Function summary() which creates a memory usage summary
12155 file with extension .mem. Reports of overlaping stack and small stack
12156 size. If the space for the stack is less than 16 bytes aslink trows a
12159 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12160 the 8051. Option 'y' for memory summary output file.
12162 Changes to sdcc (All the changes are marked with 'JCF'):
12164 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12166 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12167 overlaying area for it (uses RegBankUsed[4]).
12169 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12170 bank zero as used by default. By default aslink locates the stack
12171 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12172 the creation of the .mem file. Delegates the allocation of data area
12173 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12174 the begining of the stack area to aslink.
12176 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12177 glue() in SDCCglue.c creates an area for it.
12179 2002-09-03 Borut Razem <borut.razem AT siol.net>
12180 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12181 sdcc/src/pic/glue.c:
12182 introduced atexit() handler for teporay files removal in case of
12183 errors, assertions, ...
12185 2002-08-29 Borut Razem <borut.razem AT siol.net>
12186 * sdcc/support/cpp2/auto-host_vc_in.h:
12187 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12188 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12189 Maybe there is a similar problem with BORLANDC? It should be checked!
12191 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12192 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12193 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12194 was not executed, and the compiler (cl) launched a warning:
12195 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12197 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12198 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12200 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12201 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12203 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12204 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12205 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12206 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12207 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12208 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12209 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12210 - added Release configuration in VS projects
12211 - review of compiler an linker options
12212 - VC .exe files are generated in bin_vc directory, not to interfere
12213 with binaries generated from other projects (cygwin, mingw, bcc ...)
12215 * sdcc/src/yacc.dsp: added
12217 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12218 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12219 and insert the version number definitions from .version
12221 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12223 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12224 added - genarate auto-host.h using auto-host_vc_in.h as template
12227 removed from CVS, generated automatically
12229 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12230 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12232 2002-08-11 Borut Razem <borut.razem AT siol.net>
12233 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12235 2002-08-10 Borut Razem <borut.razem AT siol.net>
12236 * src/SDCCmain.c (main):
12237 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12238 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12239 The consequence was that some temporary files were not removed.
12242 unification of code in functions tempfilename() and tempfile():
12243 function tempnam() is defined in Visual Studio 6.0 and .NET
12245 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12247 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12248 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12249 - removed compiler command line option /WX: Treats all warnings as errors
12250 - update a list of source files, included into the project
12252 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12253 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12254 changed project type to Generic Project so that can be correcly converted to VS.NET project
12256 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12258 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12260 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12262 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12263 added return 0 statements after assert() to make compiler happy
12265 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12266 added newline in the def file to keep MSC compiler satisfied
12268 * sdcc/src/z80/gen.c:
12269 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12270 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12271 - solved MSC error in function aopDump()
12273 * sdcc_vc.h: define PREFIX as "\\sdcc"
12275 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12276 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12279 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12280 - Rewrote the register banking algorithm.
12281 - Added pCode live-range analysis to registers (for now, only non-used and
12282 singly-used registers optimized away)
12284 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12286 * 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.

12317 * src/SDCCval.c: fixed bug #532436
12319 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12321 Added "char *Processor" field to the port structure.
12324 Added -p option. Allows port dependent processor to be specified.
12327 Initialized the new field char *Processor field to NULL in all ports
12330 Compiler generated registers for interrupt context saving
12331 were not getting allocated.
12333 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12336 Fixed left shift. Will promote the left side of a left shift
12337 if a) left shifting more than size of operand or b) when assigned
12338 to something size > size of left side
12340 2002-03-14 Scott Dattalo <scott AT dattalo.com>

12355 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
12357 2002-03-04 johanknol <johanknol AT manik>
12359 * /src/SDCCval.c: fixed
12361 const unsigned char arr[][2] = { { 0, 1 } };
