2245 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2247 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2248 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2250 One basic decision: e.g. src/clean.mk includes further files. In order
2251 to make this work there are two solutions:
2252 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2253 run configure on them. This way they can use
2254 'include $(srcdir)/port-clean.mk'
2255 - always include clean.mk by the Makefile at the same level. To avoid
2256 that `make clean` tries to include and build Makefile.dep the
2257 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2258 implemented, because now even `make uninstall` doesn't create
2259 Makefile.in. clean.mk could be eliminated by pasting it in
2262 * debugger/mcs51/Makefile.in: build own objects from library sources
2263 (SLIB, SDCC) in current directory
2265 * configure, configure.in: renamed --disable-device-lib-build in
2266 --disable-device-lib; added --enable-doc, the required tools are
2267 searched by configure; added result message; the toolchain for the
2268 belonging ports are now only built, if the port is enabled.
2270 * support/regression/*: all output is written in directory gen, because
2271 the fwk and ports directories don't livet in the build tree using vpath
2273 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2274 --disable-device-lib, added --enable-doc, added section VPATH
2276 * sim/ucsim/configure.in,
2277 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2278 z80 are enabled by default
2280 2006-04-24 Raphael Neider <rneider AT web.de>
2282 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2283 to config word, "pic14_"-prefixed some extern functions
2284 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2285 config word has been found
2286 * src/pic/device.h: added prototypes
2287 * src/pic/pcode.c: added "pic14_"-prefix where needed
2288 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2290 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2302 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
2303 registers that have not been assigned proper liveranges,
2304 fixes #1469504 and #1474602,
2305 (pCodeRegOptimizeRegUsage): fixed typo in comment

2309 * device/examples/main8051.c: deleted - it was removed from CVS

2551 implemented patch 1120823 Thanks to Willy De la Court (normal
2552 interrupts need an interrupt number now if they are made critical),
2553 and enabled nesting of critical functions though not for gbz80
2554 (genCritical, genEndCritical): added functions
2555 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2556 * src/z80/mappings.i: added "ei" to all mappings

2565 2006-03-16 Raphael Neider <rneider AT web.de>
2567 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
2568 the left operand is shorter than the result (c* = lit-c* + int),
2570 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2573 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2575 * src/.version: increased version number to 2.5.5
2576 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2577 linking is done manually in pic16 port's _linkEdit,
2578 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2579 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2580 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2581 allocate asmop as AOP_ACC,
2582 (aopForRemat): added parameter 'bool result' in function declaration,
2583 (pic16_aopGet): return AOP_ACC when accessing WREG,
2584 (pic16_popGetTempReg): minor modification,
2585 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2586 'pic16_allocWithIdx',
2587 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
2588 calling function in absolute addresses,
2589 (genAssign): take into account AOP_ACC asmop,
2590 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
2591 * src/pic16/pcoderegs.c: some debug functions and lines added,

2593 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2595 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2596 call to allocReg, not by manually allocating a new one,
2597 (pic16_assignRegisters): now before going through the register

2626 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2627 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

2649 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
2651 2006-03-06 Borut Razem <borut.razem AT siol.net>
2653 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2654 made the linker quiet
2656 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2658 * src/pic16/gen.c (genPcall): fixed bug #1443644
2659 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2660 which dumps before the function entry point a data byte which represents
2661 the number of the local variables used by the specified function, added
2662 'xinst' for initial support for Extended Instruction Support,
2663 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2664 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2665 port->fun_prefix anymore (may change later),

2667 _main (this should take care the --main-return command line option in
2669 (genOr): removed some legacy pic-port instructions,
2670 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2671 performing operations with SFR's causes data to be written more than

2679 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2680 (deassignLRs): *** perhaps the most important change, old 'for' code
2681 (commented out for reference), didn't account for some registers which
2682 were left marked 'not free' after a pointer operation. The change
2683 reduces register usage a lot in some cases

4958 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4959 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4960 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4961 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4962 always available in leading double underscore form. The C99 support is
4963 mostly missing, but it's a start.
4964 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4965 reserved identifier "__data".
4967 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

5041 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5043 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5045 * device/lib/printf_large.c: removed inline assembly for portability and
5046 readability. Use printf_fast if speed or size are more important.
5047 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5048 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5050 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5052 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5053 prevent compiler warning
5055 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5057 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5058 moved to level 0 and declared as static. Also they are explicit
5059 placed in access bank. This was necessery because some times they
5060 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5061 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5062 optimizations. Currently only compare to unsigned char is implemented,
5063 * src/pic16/gen.c: added fReturnIdx array,
5064 * (struct resolvedIfx) is moved to gen.h and made public,
5065 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5066 * (aopForSym): added an optimization to directly store in stack of
5067 the operand of a SEND iCode,
5068 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5069 but as registers instead (AOP_REG) using the fReturnIdx array,
5070 * (pic16_freeAsmop): remove the freed register from the
5071 _G.sregsAlloc field,
5072 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5073 a compare of 'WREG',
5074 * (pic16_popGetTempRegCond): changed function prototype, now
5075 function takes also a bitVector argument v which holds the current
5076 set of registers that are allocated for stack access by aopForSym,
5077 registers allocated in aopForSym for accessing stack symbols are not
5078 any more part of the functions usedRegs field,
5079 * (genCall): some times aopOp is called for a stack variable to be
5080 send, aopForSym might perform the push, if this is true make sure
5081 that genCall doesn't push the variable twice by testing _G.resDirect,
5082 * (genFunction): changed testing for unspecified interrupt number
5083 from 256 to INTNO_UNSPEC,
5084 * modified selection scheme of frame pointer generation. Previously
5085 if function did use local registers a frame pointer was generated,
5086 now a frame pointer is generated only if function has arguments
5087 (that need PLUSW2 register access), or has stack arguments, or the
5088 compiler is not instructed to omit the frame pointer,
5089 * (genEndFunction): before restoring local registers that were saved
5090 in the function preamble, also restore the registers that *might*
5091 have been allocated for stack access,
5092 * (genRet): removed some old comments,
5093 * (genCmp, the active (RN's) version): added a call to the
5094 pic16_genCmp_special function to perform the compare with a more
5095 robust and optimized way,
5096 * (genInline): a feature has been added in inline code generation,
5097 which allows a wildcard variable substitution when writing inline
5098 assembly. Code is incomplete and experimental therefore undocumented,
5099 * (genCast): changed order of aopOp for result and right to allow
5100 aopForSym to directly load the result if possible,
5101 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5102 perform an optimized compare on some selected special occasions,
5103 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5104 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5105 generate an IVT any more,
5106 * src/pic16/main.c (pic16_optionsTable): added command line option
5108 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5109 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5111 * src/pic16/NOTES: Raphael Neider added in list of active developers
5112 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5113 jumptable_end to prevent bug #,
5114 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5115 inCond and outCond fields,
5116 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5117 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5118 turn off register spilling,
5119 * (packRegsForOneUse): synced with other ports' versions although it
5120 is not used currently,
5121 * (pic16_packRegisters): added an optimization while reading
5122 structure bitfields, some registers may be saved (malloc code is
5123 decreased by 80 bytes)
5125 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5127 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5128 left is a bitfield, if yes, then don't optimize assignment. Perhaps

5771 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5772 Now 4 algorithms for mcs51 jumptable generation are used:
5773 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

5807 * added libc directory. The current version of LibC contains string
5808 functions, ctype functions and macros and some functions of the
5809 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5810 be extensively tested in the future. Standard disclaimer here.
5811 Library is not automatically build yet. But one can build it by

5823 * (pic16_storeForReturn): optimized return of 0,
5824 * (genCmp): experimental code for new genCmp which uses PIC18's
5825 special compare&skip instructions. Initial tests fail some times
5826 with variables grater than 1 byte in size, so new code is disabled,
5827 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5829 * (genCast): began a fix to optimize the casting of a bit to another
5830 bit, now assigning a bitfield to another bitfield will fail, sorry,

8856 loaded with the linker search paths (-L arguments) and the libraries
8857 to be linked with the current source (-l arguments). Changes
8858 currently will affect only the pic16 port.
8859 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8860 include path the port specific paths and port specific libraries,
8861 * gplink command now contains the $3 argument,

8879 Documenting changes from previous commits.
8880 * configure.in (version 1.56),
8881 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8882 when generating output files to configure the pic16 library,
8883 but now I've commented it out, since gputils aren't installed in the
8884 SF compile farm, so library won't compile
8886 * device/lib/Makefile.in (version 1.56): initially I've added in
8887 target 'all' the prerequestive 'model-pic16' so it compiled the
8888 pic16 library, but now I've commented it out for the same reasons
8890 * added targets 'model-pic16' and 'objects-pic16' to compile the
8892 * added target 'port-specific-objects-pic16' to handle the
8893 generated libraries and copy them into the build/ directory
8894 * added target 'clean-intermediate-pic16' to clean intermediate
8895 files into pic16 directory
8896 * in target 'installdirs' added line to create directory pic16 in

9140 * support/valdiag/tests/overflow.c: added
9141 * src/SDCCast.c (decorateType),
9142 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
9143 LEFT_OP (left shift)
9145 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9147 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9148 (default behaviour).
9150 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9152 A python script to validate compiler diagnostic messages. It can be
9153 used to verify that sdcc complains about bad c source code and
9154 gives a good location of the error.
9155 * support/valdiag/Makefile,
9156 * support/valdiag/valdiag.py,
9157 * support/valdiag/tests/*
9159 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9161 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
9162 * src/SDCCsymt.c (newEnumType),
9164 * support/Util/SDCCerr.c,
9165 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
9167 * support/regression/tests/enum.c: added test for enum values that
9168 require at least 2 bytes of storage.
9170 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9172 * src/common.h: added ifndef/define/endif macros
9173 around the header file.
9174 Bug reported from Jesus Calvino-Fraga
9176 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9178 * sdcc.spec: updated
9179 * device/include/Makefile.in: don't install CVS directories
9180 * device/lib/Makefile.in: added removal of CVS directories after install
9181 * doc/Makefile: fixed install, added local_icons
9182 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9183 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9184 * src/ds390/gen.c (genRightShift): fixed bug #870788
9185 * src/SDCCast.c (decorateType): fixed bug #870781
9187 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9189 PIC16 port related changes:
9190 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9191 added variable stackPos,
9193 * gen.c: genCall, assignResultValue: added support for
9194 pushing/retrieving function parameters to/from stack,
9195 genFunction,genEndFunction: setup stack frame for the
9197 genAddrOf: will be changed according to bug 863624
9199 * added files genutils.c and genutils.h which contain gen*
9200 debugged and optimised functions extracted from gen.c
9202 * glue.c: added variable 'externs' which holds extern symbols,
9203 pic16emitRegularMap: is modified to properly handle relocatable
9204 symbols under the new scheme,
9205 pic16createInterruptVect: is modified
9206 pic16printPublics: is modified to emit 'global' assembler directives,
9207 added pic16_printExterns to print extern symbols,
9208 pic16glue: initializes stack/frame pointer in the beginning of
9209 the assembly output. Temporary hack, will be corrected later,
9210 because gplink yet does not support stack and SDCC does not
9211 yet support a type of crt0.o object to create the final binary.
9213 * Removed many lines that contain 8051 legacy code.
9214 * The code is finally placed under a 'code' directive.
9215 * Added port specific options.
9217 * _process_pragma: simplified since now we do not need *special*
9218 include file to define SFR registers. But a separate header
9219 will be needed. This will be developed later.
9220 * _pic16_parseOptions: added, parses port specific options:
9221 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9222 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9223 --preplace-udata-with=
9225 * _pic16_setDefaultOptions: modified to initialize section names,
9226 but hack is temporarly out of order since it needs improvement.
9227 * _pic16_genAssemblerPreamble: configuration words are emitted by
9228 their address instead of their name. This part is incomplete and
9229 supports only the 18Fxx2 devices. Other devices will emit an error
9230 during assembly since they do not contain the same set of config
9232 * _pic16_genIVT: is modified,
9234 * pcode.c: added definitions for some hardware registers that are needed
9236 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9237 All PCI entries are updated. Now LFSR is supported.
9238 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9239 * added pic16_newpCodeOpLit2 to support instructions with
9240 two literal arguments
9241 * pic16_pCode2str: corrected code that emits assembler instructions
9242 with two literal operands and those that have an access bit modifier
9243 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9244 this fixes a bug which caused some labels to be lost, when an
9245 assembler directive was added, i.e. banksel,
9246 * pic16_FixRegisterBanking: improved logic that causes the insertion
9248 * InlineFunction: functions that are called once, are not any more
9249 inlined. This can be a port option in the future,
9251 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9253 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9254 hold the corresponding uninitialized symbols,
9255 * pic16_allocProcessorRegister: registers have explicit marked the
9257 * pic16_allocInternalRegister: registers are explicit marked as
9259 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9260 processing list, so bit registers were lost,
9263 * ralloc.h: added field 'accessBank' and original symbol operand
9264 in register definition,
9265 * removed the field isMapped from register definition,
9267 ** Several functions have been removed from various sources:
9268 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9269 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9270 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9271 pic16_assignRelocatableRegisters
9273 ** others have been introduced:
9274 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9275 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9277 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9279 * support/scripts/inc2h.pl: changed definition of BIT_AT
9280 to emit 'sbit at' instead of 'bit at'. This was a request.
9282 PIC16 port related preliminary changes:
9283 * gen.c: prefixed function popRegFromString with
9284 pic16_ and all references to it corrected
9285 * pcode.c: all pic16_pc_* hardware registers prefixed
9286 with underscore (_),
9287 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9288 * ralloc.c: newReg(): when register is REG_SFR then
9289 set address to rIdx,
9290 pic16_allocProcessorRegister(): marks register wasUsed=0
9291 pic16_writeUsedRegs(): added a call to assign processor
9292 registers via pic16_assignFixedRegisters
9294 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9296 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9297 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9298 variables in unused register banks. Also the SSEG is placed
9299 wherever there is enough space for it, and IDATA can be anywhere
9300 in internal RAM. For now compile using -Wl-Y[stack_size].
9301 The mem file is different for this option as well, since it
9302 makes no sense of talking about DSEG lenght.
9304 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9306 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9307 in certain cases, e.g. when ROM assignment, patch provided
9308 from Albert den Haan.
9310 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9453 * src/mcs51/peephole.def,
9454 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
9455 (allows non-interrupt and interrupt code to safely compete for a resource

9466 multiply defined with mismatching "at" address.
9468 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9470 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

9549 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9551 * src/SDCCast.c (decorateType): disabled a transformation I added in
9552 revision 1.188 (access to fields of a structure at an absolute address);
9553 it breaks with bitfields, extern declarations, and gcse analysis.
9554 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9555 could be assigned through a pointer, so don't complain.
9556 * src/SDCCast.c (astErrors),
9558 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

10138 genCodePointerGet, genGenPointerGet, genFarPointerSet,
10139 genGenPointerSet): handle AOP_DPTR correctly when loading dptr
10140 (ralloc doesn't intentionally do this now, but perhaps later)
10141 * src/mcs51/ralloc.c (serialRegAssign, fillGaps),
10142 * src/ds390/ralloc.c (serialRegAssign, fillGaps): fixed some

10176 * src/ds390/gen.c (genFunction, genEndFunction): Moved save
10177 and restore of EA so that stack offsets to parameters are
10178 correct when using both critical and reentrant/stack-auto.
10179 * src/z80/gen.c (aopOp): removed erroneous assertion about sloc
10180 size (can be triggered in error if sloc is shared between
10181 different sized objects)
10182 * device/include/float.h: fixed macros to explicitly use
10183 unsigned long where needed
10185 2003-09-15 Bernhard Held <bernhard AT bernhardheld.de>

10193 * src/SDCCsymt.c (sclsFromPtr),
10195 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10196 support for standard C idiom of memory mapped variables; for
10197 example, *((xdata int*)0x1234) = 1 is now internally equivalent
10198 to xdata int at 0x1234 tempvar = 1.
10199 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
10200 provided by Akiya ISHIDA

10216 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10218 Fixed bug #621531 (const & volatile confusion in the type chain).
10219 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10220 refer to the const or volatile state of the pointer itself.
10232 * src/pic16/ralloc.c
10233 * support/regression/tests/const.c
10235 2003-09-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10237 When checking for duplicated modules, use absolute paths

10290 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
10292 * device/lib/_mullong.c: replaced int by short for gcc
10294 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10296 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
10297 and JUMPTABLE iCodes properly now (worked by accident before)
10298 * src/mcs51/gen.c (leftRightUseAcc),
10299 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10300 iCode properly now. Use getSize instead of nRegs since a & b
10301 aren't part of the nRegs tally.
10303 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10305 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10314 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
10315 copied from genNearPointerSet()
10316 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10317 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10318 If they pop r0/r1 they must be called in the opposite order than aopOp().
10319 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10320 (resp. --stack-auto), prepared for --xstack
10322 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10324 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10326 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10328 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
10329 these ports have their own __sdcc_external_start()
10331 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10333 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10334 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10335 type for bits was changed. It resulted in bit variables becoming
10336 global, which is not permitted in PIC 14 assembly output.
10338 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10340 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10342 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10344 Z80 and MCS51 linkers complaint if a public symbol is defined
10345 in more than one library module:

10351 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10353 A few small changes that speed up the peephole optimizer.
10357 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10359 Try to make the peephole optimizer smarter by maintaining
10360 an association between the assembly source code and the
10361 iCodes that originated them. Put this information to use
10362 with a new peephole rule condition "notVolatile" so that
10363 the rules can be aggressive yet still safe.
10368 * src/mcs51/peeph.def
10370 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10374 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10375 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10376 if the left or right operand symbols have the accuse flag set.
10378 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10380 Changed the type of the result of the ! (NOT) operator to char;
10381 previously it returned the same type as the source. This allows
10382 us to eliminate all the genFloatNot functions (all of its target
10383 implementations were very buggy) since !float can use the same
10386 * src/SDCCicode.c (ast2iCode): ! returns char
10387 * src/mcs51/gen.c (genNot, genNotFloat),
10388 * src/ds390/gen.c (genNot, genNotFloat),
10389 * src/z80/gen.c (genNot, genNotFloat),
10390 * src/pic/gen.c (genNot, genNotFloat),
10391 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

10395 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10396 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10397 during interrupts. Ensure WSAVE is located at a shared bank address.
10398 2. Fixed page selection in some places
10399 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10400 the registers name strings.
10401 4. Fixed "signed / unsigned compare" compiler warnings.
10402 5. The PIC port manages its own allocation of the general purpose
10403 registers, but makes no attempt to reuse them. As a result when
10404 compiling it soon runs out of general purpose registers. Some
10405 additional code was added to the files pcode.c and device.c to walk
10406 through the function call tree and rename the registers so that they
10416 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10417 genPlus() & genMinus() when the result is the same as left or right
10419 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10423 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10425 Made bitfield a distinct type from bit so that bitfields
10426 convert as per ANSI C and bits retain their traditional
10427 boolean style behaviour. Implemented bitfield support in
10435 * src/ds390/gen.c: bit v bitfield split
10436 * src/z80/gen.c: New support for bitfields
10437 * support/regression/tests/bitfields.c: reenabled z80,
10440 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10442 Rules 246.x, 247.x relate to bitfields, the others speed up
10443 access to xdata mapped I/O devices.
10445 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10447 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10449 Cleaned up genPackBits and genUnpackBits and added two helper
10450 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10451 for literal assignments in genPackBits (thanks to Frieder for
10457 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10459 Fixed bug #748310 (pointer to function type mishandled when the
10460 function name is omitted). Also fixed a SIGSEGV when a function
10461 attribute (reentrant, etc) is used on a non-function or on a
10462 function but misplaced before the parameter list.
10464 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10466 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10467 * support/Util/SDCCerr.h,
10468 * support/Util/SDCCerr.c: Added func attr misuse error msg
10470 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10472 Fixed bug #787649 by anonymous
10473 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10474 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10476 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10478 Fixed numerous bitfield problems.
10480 * src/SDCC.y: More bitfield related error checking

10487 * support/regression/tests/bitfields.c: tests added
10489 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10491 Made the constant following the "interrupt" keyword optional. If
10492 omitted, the function will not automatically be given an entry
10493 in the interrupt vector table (similar to #pragma NOIV, but
10494 less syntacticly kludgy). The interrupt number is also now
10495 range checked. Also fixed a bug in the high order bit example

10509 * src/SDCCicode.c (operandOperation): rewritten some ops
10510 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
10511 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10513 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10514 be re-activated by defining REDUCE_LITERALS)
10515 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10516 unsigned, but are signed by default
10517 * src/SDCCval.c (constVal): rearranged
10518 * src/SDCCval.c (valMod): preliminary fix
10519 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10559 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10560 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10561 constants are unsigned; added recognition of "u" flag for unsigned
10562 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10563 * src/SDCCval.c (valDiv, valMod): fixed signdness

11027 support for the PIc16 port in the ports table, when executing
11028 the compiler with no port specified on command line, a default
11029 port is selected with the new macro DEFAULT_PORT which is
11030 defined in port.h, in setDefaultOptions() linkOptions is removed
11031 from initialization assignment, since now it is a set,
11032 parseCmdLine uses setParseWithComma for linkOptions, in
11033 linkEdit() linkOptions are accessed with new function indexSet()
11034 which returns the i'th item of a set variable. See SDCCset.c, in
11035 linkEdit() when calling buildCmdLine(), added linkOptions as
11036 last argument. Now users can pass arguments to gplink via the

11051 gpasm complaining and test the linkage with gplink, _linkCmd and
11052 _asmCmd changed to be more gplink and gpasm friendly
11053 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11054 produced an error when parsed, peep rule 12 is added to utilize
11055 movff, but it is commented out since the pCode does not support
11056 yet a command with 2 address arguments

12118 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12119 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12121 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12123 * in /sdcc/as/mcs51/ changed these files in order to create an
12124 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12125 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12126 following files to include the previous two files: aslink.dsp,
12127 Makefile.aslink, Makefile.bcc, and Makefile.in.
12129 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12130 .adb instead of .cdb
12132 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12134 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12135 value from option --iram-size.
12137 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12139 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12142 2002-09-18 <wiml AT hhhh.org>
12144 * SDCClrange.h: exposed setFromRange() and setToRange()
12145 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12146 packRegsForAccUse() (bug 542397)
12147 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12148 multiple times and emitting the fetch operations more than once
12149 added aopGetUsesAcc() function to allow binary operators to
12150 fetch their operands in the correct order; made genMinus() emit
12151 compact code for X = LITERAL - Y
12153 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12154 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12155 sprintf() in line 1267.
12157 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12158 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12161 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12162 Changes to aslink (All the changes are marked with 'JCF'):
12164 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12167 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12168 area BSEG. Also moves, if possible, the DATA area down into the internal
12169 ram so more space is available.
12171 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12174 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12175 not bytes. Function summary() which creates a memory usage summary
12176 file with extension .mem. Reports of overlaping stack and small stack
12177 size. If the space for the stack is less than 16 bytes aslink trows a
12180 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12181 the 8051. Option 'y' for memory summary output file.
12183 Changes to sdcc (All the changes are marked with 'JCF'):
12185 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12187 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12188 overlaying area for it (uses RegBankUsed[4]).
12190 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12191 bank zero as used by default. By default aslink locates the stack
12192 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12193 the creation of the .mem file. Delegates the allocation of data area
12194 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12195 the begining of the stack area to aslink.
12197 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12198 glue() in SDCCglue.c creates an area for it.
12200 2002-09-03 Borut Razem <borut.razem AT siol.net>
12201 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12202 sdcc/src/pic/glue.c:
12203 introduced atexit() handler for teporay files removal in case of
12204 errors, assertions, ...
12206 2002-08-29 Borut Razem <borut.razem AT siol.net>
12207 * sdcc/support/cpp2/auto-host_vc_in.h:
12208 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12209 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12210 Maybe there is a similar problem with BORLANDC? It should be checked!
12212 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12213 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12214 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12215 was not executed, and the compiler (cl) launched a warning:
12216 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12218 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12219 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12221 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12222 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12224 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12225 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12226 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12227 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12228 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12229 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12230 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12231 - added Release configuration in VS projects
12232 - review of compiler an linker options
12233 - VC .exe files are generated in bin_vc directory, not to interfere
12234 with binaries generated from other projects (cygwin, mingw, bcc ...)
12236 * sdcc/src/yacc.dsp: added
12238 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12239 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12240 and insert the version number definitions from .version
12242 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12244 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12245 added - genarate auto-host.h using auto-host_vc_in.h as template
12248 removed from CVS, generated automatically
12250 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12251 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12253 2002-08-11 Borut Razem <borut.razem AT siol.net>
12254 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12256 2002-08-10 Borut Razem <borut.razem AT siol.net>
12257 * src/SDCCmain.c (main):
12258 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12259 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12260 The consequence was that some temporary files were not removed.
12263 unification of code in functions tempfilename() and tempfile():
12264 function tempnam() is defined in Visual Studio 6.0 and .NET
12266 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12268 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12269 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12270 - removed compiler command line option /WX: Treats all warnings as errors
12271 - update a list of source files, included into the project
12273 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12274 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12275 changed project type to Generic Project so that can be correcly converted to VS.NET project
12277 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12279 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12281 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12283 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12284 added return 0 statements after assert() to make compiler happy
12286 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12287 added newline in the def file to keep MSC compiler satisfied
12289 * sdcc/src/z80/gen.c:
12290 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12291 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12292 - solved MSC error in function aopDump()
12294 * sdcc_vc.h: define PREFIX as "\\sdcc"
12296 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12297 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12300 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12301 - Rewrote the register banking algorithm.
12302 - Added pCode live-range analysis to registers (for now, only non-used and
12303 singly-used registers optimized away)
12305 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12307 * 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.

12334 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12336 2002-03-28 Johan Knol <johan AT balder>
12338 * src/SDCCval.c: fixed bug #532436
12340 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12342 Added "char *Processor" field to the port structure.
12345 Added -p option. Allows port dependent processor to be specified.
12348 Initialized the new field char *Processor field to NULL in all ports
12351 Compiler generated registers for interrupt context saving
12352 were not getting allocated.
12354 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12357 Fixed left shift. Will promote the left side of a left shift
12358 if a) left shifting more than size of operand or b) when assigned
12359 to something size > size of left side
12361 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12363 tons of changes. Register allocation has been
12364 rewritten. Added customization for the various PICs. Flow
12365 analysis is restructured. ...
12367 * src/pic/device.h:
12370 * src/pic/device.c:
12371 Added. device.c is a PIC port hack to accomodate variations
12374 2002-03-13 Michael Hope <michaelh AT vroom>
12376 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
12378 2002-03-04 johanknol <johanknol AT manik>
12380 * /src/SDCCval.c: fixed
12382 const unsigned char arr[][2] = { { 0, 1 } };
12383 t18.c:1: error: Initializer element is not constant
12385 2002-03-04 bela <bela AT manik>
