2260 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2262 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2263 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2265 One basic decision: e.g. src/clean.mk includes further files. In order
2266 to make this work there are two solutions:
2267 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2268 run configure on them. This way they can use
2269 'include $(srcdir)/port-clean.mk'
2270 - always include clean.mk by the Makefile at the same level. To avoid
2271 that `make clean` tries to include and build Makefile.dep the
2272 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2273 implemented, because now even `make uninstall` doesn't create
2274 Makefile.in. clean.mk could be eliminated by pasting it in
2277 * debugger/mcs51/Makefile.in: build own objects from library sources
2278 (SLIB, SDCC) in current directory
2280 * configure, configure.in: renamed --disable-device-lib-build in
2281 --disable-device-lib; added --enable-doc, the required tools are
2282 searched by configure; added result message; the toolchain for the
2283 belonging ports are now only built, if the port is enabled.
2285 * support/regression/*: all output is written in directory gen, because
2286 the fwk and ports directories don't livet in the build tree using vpath
2288 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2289 --disable-device-lib, added --enable-doc, added section VPATH
2291 * sim/ucsim/configure.in,
2292 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2293 z80 are enabled by default
2295 2006-04-24 Raphael Neider <rneider AT web.de>
2297 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2298 to config word, "pic14_"-prefixed some extern functions
2299 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2300 config word has been found
2301 * src/pic/device.h: added prototypes
2302 * src/pic/pcode.c: added "pic14_"-prefix where needed
2303 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2305 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2666 2006-03-06 Borut Razem <borut.razem AT siol.net>
2668 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2669 made the linker quiet
2671 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>

2675 which dumps before the function entry point a data byte which represents
2676 the number of the local variables used by the specified function, added
2677 'xinst' for initial support for Extended Instruction Support,
2678 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2679 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2680 port->fun_prefix anymore (may change later),
2681 (genFunction, genEndFunction): do not store/restore local registers for
2682 _main (this should take care the --main-return command line option in
2684 (genOr): removed some legacy pic-port instructions,
2685 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2686 performing operations with SFR's causes data to be written more than

2696 (commented out for reference), didn't account for some registers which
2697 were left marked 'not free' after a pointer operation. The change
2698 reduces register usage a lot in some cases

5056 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5058 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5060 * device/lib/printf_large.c: removed inline assembly for portability and
5061 readability. Use printf_fast if speed or size are more important.
5062 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5063 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5065 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5067 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5068 prevent compiler warning
5070 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5072 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5073 moved to level 0 and declared as static. Also they are explicit
5074 placed in access bank. This was necessery because some times they
5075 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5076 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5077 optimizations. Currently only compare to unsigned char is implemented,
5078 * src/pic16/gen.c: added fReturnIdx array,
5079 * (struct resolvedIfx) is moved to gen.h and made public,
5080 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5081 * (aopForSym): added an optimization to directly store in stack of
5082 the operand of a SEND iCode,
5083 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5084 but as registers instead (AOP_REG) using the fReturnIdx array,
5085 * (pic16_freeAsmop): remove the freed register from the
5086 _G.sregsAlloc field,
5087 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5088 a compare of 'WREG',
5089 * (pic16_popGetTempRegCond): changed function prototype, now
5090 function takes also a bitVector argument v which holds the current
5091 set of registers that are allocated for stack access by aopForSym,
5092 registers allocated in aopForSym for accessing stack symbols are not
5093 any more part of the functions usedRegs field,
5094 * (genCall): some times aopOp is called for a stack variable to be
5095 send, aopForSym might perform the push, if this is true make sure
5096 that genCall doesn't push the variable twice by testing _G.resDirect,
5097 * (genFunction): changed testing for unspecified interrupt number
5098 from 256 to INTNO_UNSPEC,
5099 * modified selection scheme of frame pointer generation. Previously
5100 if function did use local registers a frame pointer was generated,
5101 now a frame pointer is generated only if function has arguments
5102 (that need PLUSW2 register access), or has stack arguments, or the
5103 compiler is not instructed to omit the frame pointer,
5104 * (genEndFunction): before restoring local registers that were saved
5105 in the function preamble, also restore the registers that *might*
5106 have been allocated for stack access,
5107 * (genRet): removed some old comments,
5108 * (genCmp, the active (RN's) version): added a call to the
5109 pic16_genCmp_special function to perform the compare with a more
5110 robust and optimized way,
5111 * (genInline): a feature has been added in inline code generation,
5112 which allows a wildcard variable substitution when writing inline
5113 assembly. Code is incomplete and experimental therefore undocumented,
5114 * (genCast): changed order of aopOp for result and right to allow
5115 aopForSym to directly load the result if possible,
5116 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5117 perform an optimized compare on some selected special occasions,
5118 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5119 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5120 generate an IVT any more,
5121 * src/pic16/main.c (pic16_optionsTable): added command line option
5123 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5124 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5126 * src/pic16/NOTES: Raphael Neider added in list of active developers
5127 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5128 jumptable_end to prevent bug #,
5129 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5130 inCond and outCond fields,
5131 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5132 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5133 turn off register spilling,

5784 Adding support for replacing ljmps with sjmps in jumptables
5785 generated for switch statements. For now you need to set the
5786 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5787 Now 4 algorithms for mcs51 jumptable generation are used:
5788 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5789 addresses loaded pc-relative for up to 112 cases and stack-pushing
5790 target addresses loaded with offset from dptr for up to 256 cases.

5820 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5822 * added libc directory. The current version of LibC contains string
5823 functions, ctype functions and macros and some functions of the
5824 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5825 be extensively tested in the future. Standard disclaimer here.
5826 Library is not automatically build yet. But one can build it by
5827 invoking 'make' inside the libc directory.

5838 * (pic16_storeForReturn): optimized return of 0,
5839 * (genCmp): experimental code for new genCmp which uses PIC18's
5840 special compare&skip instructions. Initial tests fail some times
5841 with variables grater than 1 byte in size, so new code is disabled,
5842 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5844 * (genCast): began a fix to optimize the casting of a bit to another
5845 bit, now assigning a bitfield to another bitfield will fail, sorry,

5854 and 1 for banking instruction,
5855 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5856 caused stop processing pCodes after a inline assembly block,
5857 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5859 registers when it shouldn't,
5860 * src/pic16/ralloc.c (allocReg): add preliminary support for
5861 supporting a limited set of temporary registers,
5863 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8871 loaded with the linker search paths (-L arguments) and the libraries
8872 to be linked with the current source (-l arguments). Changes
8873 currently will affect only the pic16 port.
8874 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8875 include path the port specific paths and port specific libraries,
8876 * gplink command now contains the $3 argument,
8877 * src/pic16/device.h,
8878 * src/pic16/device.c,: structure PIC_device is made public and

8894 Documenting changes from previous commits.
8895 * configure.in (version 1.56),
8896 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8897 when generating output files to configure the pic16 library,
8898 but now I've commented it out, since gputils aren't installed in the
8899 SF compile farm, so library won't compile
8901 * device/lib/Makefile.in (version 1.56): initially I've added in
8902 target 'all' the prerequestive 'model-pic16' so it compiled the
8903 pic16 library, but now I've commented it out for the same reasons
8905 * added targets 'model-pic16' and 'objects-pic16' to compile the
8907 * added target 'port-specific-objects-pic16' to handle the
8908 generated libraries and copy them into the build/ directory
8909 * added target 'clean-intermediate-pic16' to clean intermediate
8910 files into pic16 directory
8911 * in target 'installdirs' added line to create directory pic16 in

8915 added lines to copy all header files to installation path,
8916 * in target 'installdirs' added line create directory for pic16
8917 headers in the installation path

9141 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
9142 how the function variable allocation summary is displayed; also
9143 include information about variables allocated to the overlay
9146 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9148 * as/mcs51/lkmain.c: Help about -Y option
9149 * as/mcs51/lkarea.c: Fixed gcc warnings
9151 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9153 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
9155 * support/valdiag/tests/overflow.c: added
9156 * src/SDCCast.c (decorateType),
9157 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
9158 LEFT_OP (left shift)
9160 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9162 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
9163 (default behaviour).
9165 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9167 A python script to validate compiler diagnostic messages. It can be
9168 used to verify that sdcc complains about bad c source code and
9169 gives a good location of the error.
9170 * support/valdiag/Makefile,
9171 * support/valdiag/valdiag.py,
9172 * support/valdiag/tests/*
9174 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9176 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
9177 * src/SDCCsymt.c (newEnumType),
9179 * support/Util/SDCCerr.c,
9180 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
9182 * support/regression/tests/enum.c: added test for enum values that
9183 require at least 2 bytes of storage.
9185 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9187 * src/common.h: added ifndef/define/endif macros
9188 around the header file.
9189 Bug reported from Jesus Calvino-Fraga
9191 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9193 * sdcc.spec: updated
9194 * device/include/Makefile.in: don't install CVS directories
9195 * device/lib/Makefile.in: added removal of CVS directories after install
9196 * doc/Makefile: fixed install, added local_icons
9197 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9198 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9199 * src/ds390/gen.c (genRightShift): fixed bug #870788
9200 * src/SDCCast.c (decorateType): fixed bug #870781
9202 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9204 PIC16 port related changes:
9205 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9206 added variable stackPos,
9208 * gen.c: genCall, assignResultValue: added support for
9209 pushing/retrieving function parameters to/from stack,
9210 genFunction,genEndFunction: setup stack frame for the
9212 genAddrOf: will be changed according to bug 863624
9214 * added files genutils.c and genutils.h which contain gen*
9215 debugged and optimised functions extracted from gen.c
9217 * glue.c: added variable 'externs' which holds extern symbols,
9218 pic16emitRegularMap: is modified to properly handle relocatable
9219 symbols under the new scheme,
9220 pic16createInterruptVect: is modified
9221 pic16printPublics: is modified to emit 'global' assembler directives,
9222 added pic16_printExterns to print extern symbols,
9223 pic16glue: initializes stack/frame pointer in the beginning of
9224 the assembly output. Temporary hack, will be corrected later,
9225 because gplink yet does not support stack and SDCC does not
9226 yet support a type of crt0.o object to create the final binary.
9228 * Removed many lines that contain 8051 legacy code.
9229 * The code is finally placed under a 'code' directive.
9230 * Added port specific options.
9232 * _process_pragma: simplified since now we do not need *special*
9233 include file to define SFR registers. But a separate header
9234 will be needed. This will be developed later.
9235 * _pic16_parseOptions: added, parses port specific options:
9236 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9237 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9238 --preplace-udata-with=
9240 * _pic16_setDefaultOptions: modified to initialize section names,
9241 but hack is temporarly out of order since it needs improvement.
9242 * _pic16_genAssemblerPreamble: configuration words are emitted by
9243 their address instead of their name. This part is incomplete and
9244 supports only the 18Fxx2 devices. Other devices will emit an error
9245 during assembly since they do not contain the same set of config
9247 * _pic16_genIVT: is modified,
9249 * pcode.c: added definitions for some hardware registers that are needed
9251 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9252 All PCI entries are updated. Now LFSR is supported.
9253 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9254 * added pic16_newpCodeOpLit2 to support instructions with
9255 two literal arguments
9256 * pic16_pCode2str: corrected code that emits assembler instructions
9257 with two literal operands and those that have an access bit modifier
9258 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9259 this fixes a bug which caused some labels to be lost, when an
9260 assembler directive was added, i.e. banksel,
9261 * pic16_FixRegisterBanking: improved logic that causes the insertion
9263 * InlineFunction: functions that are called once, are not any more
9264 inlined. This can be a port option in the future,
9266 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9268 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9269 hold the corresponding uninitialized symbols,
9270 * pic16_allocProcessorRegister: registers have explicit marked the
9272 * pic16_allocInternalRegister: registers are explicit marked as
9274 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9275 processing list, so bit registers were lost,
9278 * ralloc.h: added field 'accessBank' and original symbol operand
9279 in register definition,
9280 * removed the field isMapped from register definition,
9282 ** Several functions have been removed from various sources:
9283 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9284 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9285 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9286 pic16_assignRelocatableRegisters
9288 ** others have been introduced:
9289 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9290 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9292 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9294 * support/scripts/inc2h.pl: changed definition of BIT_AT
9295 to emit 'sbit at' instead of 'bit at'. This was a request.
9297 PIC16 port related preliminary changes:
9298 * gen.c: prefixed function popRegFromString with
9299 pic16_ and all references to it corrected
9300 * pcode.c: all pic16_pc_* hardware registers prefixed
9301 with underscore (_),
9302 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9303 * ralloc.c: newReg(): when register is REG_SFR then
9304 set address to rIdx,
9305 pic16_allocProcessorRegister(): marks register wasUsed=0
9306 pic16_writeUsedRegs(): added a call to assign processor
9307 registers via pic16_assignFixedRegisters
9309 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9311 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9312 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9313 variables in unused register banks. Also the SSEG is placed
9314 wherever there is enough space for it, and IDATA can be anywhere
9315 in internal RAM. For now compile using -Wl-Y[stack_size].
9316 The mem file is different for this option as well, since it
9317 makes no sense of talking about DSEG lenght.
9319 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9321 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9322 in certain cases, e.g. when ROM assignment, patch provided
9323 from Albert den Haan.
9325 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9468 * src/mcs51/peephole.def,
9469 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

9564 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9566 * src/SDCCast.c (decorateType): disabled a transformation I added in
9567 revision 1.188 (access to fields of a structure at an absolute address);
9568 it breaks with bitfields, extern declarations, and gcse analysis.
9569 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9570 could be assigned through a pointer, so don't complain.
9571 * src/SDCCast.c (astErrors),
9573 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

10153 genCodePointerGet, genGenPointerGet, genFarPointerSet,
10154 genGenPointerSet): handle AOP_DPTR correctly when loading dptr
10155 (ralloc doesn't intentionally do this now, but perhaps later)
10156 * src/mcs51/ralloc.c (serialRegAssign, fillGaps),
10157 * src/ds390/ralloc.c (serialRegAssign, fillGaps): fixed some

10208 * src/SDCCsymt.c (sclsFromPtr),
10210 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10211 support for standard C idiom of memory mapped variables; for
10212 example, *((xdata int*)0x1234) = 1 is now internally equivalent
10213 to xdata int at 0x1234 tempvar = 1.

10231 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10233 Fixed bug #621531 (const & volatile confusion in the type chain).
10234 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10235 refer to the const or volatile state of the pointer itself.

10305 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
10307 * device/lib/_mullong.c: replaced int by short for gcc
10309 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10311 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
10312 and JUMPTABLE iCodes properly now (worked by accident before)
10313 * src/mcs51/gen.c (leftRightUseAcc),
10314 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10315 iCode properly now. Use getSize instead of nRegs since a & b
10316 aren't part of the nRegs tally.
10318 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10320 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10329 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
10330 copied from genNearPointerSet()
10331 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10332 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10333 If they pop r0/r1 they must be called in the opposite order than aopOp().
10334 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10335 (resp. --stack-auto), prepared for --xstack
10337 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10339 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10341 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>

10344 these ports have their own __sdcc_external_start()
10346 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10348 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10349 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10350 type for bits was changed. It resulted in bit variables becoming
10351 global, which is not permitted in PIC 14 assembly output.
10353 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10355 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10357 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10359 Z80 and MCS51 linkers complaint if a public symbol is defined

10368 A few small changes that speed up the peephole optimizer.
10372 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10374 Try to make the peephole optimizer smarter by maintaining
10375 an association between the assembly source code and the
10376 iCodes that originated them. Put this information to use
10377 with a new peephole rule condition "notVolatile" so that
10378 the rules can be aggressive yet still safe.
10383 * src/mcs51/peeph.def
10385 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10389 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10390 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10391 if the left or right operand symbols have the accuse flag set.
10393 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10395 Changed the type of the result of the ! (NOT) operator to char;
10396 previously it returned the same type as the source. This allows
10397 us to eliminate all the genFloatNot functions (all of its target
10398 implementations were very buggy) since !float can use the same
10401 * src/SDCCicode.c (ast2iCode): ! returns char

10410 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10411 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10412 during interrupts. Ensure WSAVE is located at a shared bank address.
10413 2. Fixed page selection in some places
10414 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10415 the registers name strings.
10416 4. Fixed "signed / unsigned compare" compiler warnings.
10417 5. The PIC port manages its own allocation of the general purpose
10418 registers, but makes no attempt to reuse them. As a result when
10419 compiling it soon runs out of general purpose registers. Some
10420 additional code was added to the files pcode.c and device.c to walk
10421 through the function call tree and rename the registers so that they
10431 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10432 genPlus() & genMinus() when the result is the same as left or right
10434 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10438 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10440 Made bitfield a distinct type from bit so that bitfields
10441 convert as per ANSI C and bits retain their traditional
10442 boolean style behaviour. Implemented bitfield support in
10450 * src/ds390/gen.c: bit v bitfield split
10451 * src/z80/gen.c: New support for bitfields
10452 * support/regression/tests/bitfields.c: reenabled z80,
10455 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10457 Rules 246.x, 247.x relate to bitfields, the others speed up
10458 access to xdata mapped I/O devices.
10460 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10462 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10464 Cleaned up genPackBits and genUnpackBits and added two helper
10465 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10466 for literal assignments in genPackBits (thanks to Frieder for
10472 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10474 Fixed bug #748310 (pointer to function type mishandled when the
10475 function name is omitted). Also fixed a SIGSEGV when a function
10476 attribute (reentrant, etc) is used on a non-function or on a
10477 function but misplaced before the parameter list.
10479 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10481 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10482 * support/Util/SDCCerr.h,
10483 * support/Util/SDCCerr.c: Added func attr misuse error msg
10485 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10487 Fixed bug #787649 by anonymous
10488 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10489 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10491 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10493 Fixed numerous bitfield problems.

10504 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10506 Made the constant following the "interrupt" keyword optional. If
10507 omitted, the function will not automatically be given an entry
10508 in the interrupt vector table (similar to #pragma NOIV, but
10509 less syntacticly kludgy). The interrupt number is also now
10510 range checked. Also fixed a bug in the high order bit example

10526 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10528 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10529 be re-activated by defining REDUCE_LITERALS)
10530 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10531 unsigned, but are signed by default
10532 * src/SDCCval.c (constVal): rearranged
10533 * src/SDCCval.c (valMod): preliminary fix
10534 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10574 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10575 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10576 constants are unsigned; added recognition of "u" flag for unsigned
10577 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10578 * src/SDCCval.c (valDiv, valMod): fixed signdness

11041 messages from optionsTable when a port is not configured, added
11042 support for the PIc16 port in the ports table, when executing
11043 the compiler with no port specified on command line, a default
11044 port is selected with the new macro DEFAULT_PORT which is
11045 defined in port.h, in setDefaultOptions() linkOptions is removed
11046 from initialization assignment, since now it is a set,
11047 parseCmdLine uses setParseWithComma for linkOptions, in
11048 linkEdit() linkOptions are accessed with new function indexSet()
11049 which returns the i'th item of a set variable. See SDCCset.c, in
11050 linkEdit() when calling buildCmdLine(), added linkOptions as
11051 last argument. Now users can pass arguments to gplink via the

11066 gpasm complaining and test the linkage with gplink, _linkCmd and
11067 _asmCmd changed to be more gplink and gpasm friendly
11068 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11069 produced an error when parsed, peep rule 12 is added to utilize
11070 movff, but it is commented out since the pCode does not support
11071 yet a command with 2 address arguments

12123 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12124 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

12133 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12134 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12136 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12138 * in /sdcc/as/mcs51/ changed these files in order to create an
12139 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12140 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12141 following files to include the previous two files: aslink.dsp,
12142 Makefile.aslink, Makefile.bcc, and Makefile.in.
12144 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12145 .adb instead of .cdb
12147 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12149 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12150 value from option --iram-size.
12152 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12154 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12157 2002-09-18 <wiml AT hhhh.org>
12159 * SDCClrange.h: exposed setFromRange() and setToRange()
12160 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12161 packRegsForAccUse() (bug 542397)
12162 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12163 multiple times and emitting the fetch operations more than once
12164 added aopGetUsesAcc() function to allow binary operators to
12165 fetch their operands in the correct order; made genMinus() emit
12166 compact code for X = LITERAL - Y
12168 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12169 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12170 sprintf() in line 1267.
12172 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12173 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12176 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12177 Changes to aslink (All the changes are marked with 'JCF'):
12179 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12182 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12183 area BSEG. Also moves, if possible, the DATA area down into the internal
12184 ram so more space is available.
12186 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12189 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12190 not bytes. Function summary() which creates a memory usage summary
12191 file with extension .mem. Reports of overlaping stack and small stack
12192 size. If the space for the stack is less than 16 bytes aslink trows a
12195 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12196 the 8051. Option 'y' for memory summary output file.
12198 Changes to sdcc (All the changes are marked with 'JCF'):
12200 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12202 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12203 overlaying area for it (uses RegBankUsed[4]).
12205 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12206 bank zero as used by default. By default aslink locates the stack
12207 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12208 the creation of the .mem file. Delegates the allocation of data area
12209 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12210 the begining of the stack area to aslink.
12212 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12213 glue() in SDCCglue.c creates an area for it.
12215 2002-09-03 Borut Razem <borut.razem AT siol.net>
12216 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12217 sdcc/src/pic/glue.c:
12218 introduced atexit() handler for teporay files removal in case of
12219 errors, assertions, ...
12221 2002-08-29 Borut Razem <borut.razem AT siol.net>
12222 * sdcc/support/cpp2/auto-host_vc_in.h:
12223 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12224 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12225 Maybe there is a similar problem with BORLANDC? It should be checked!
12227 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12228 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12229 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12230 was not executed, and the compiler (cl) launched a warning:
12231 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12233 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12234 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12236 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12237 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12239 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12240 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12241 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12242 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12243 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12244 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12245 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12246 - added Release configuration in VS projects
12247 - review of compiler an linker options
12248 - VC .exe files are generated in bin_vc directory, not to interfere
12249 with binaries generated from other projects (cygwin, mingw, bcc ...)
12251 * sdcc/src/yacc.dsp: added
12253 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12254 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12255 and insert the version number definitions from .version
12257 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12259 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12260 added - genarate auto-host.h using auto-host_vc_in.h as template
12263 removed from CVS, generated automatically
12265 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12266 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12268 2002-08-11 Borut Razem <borut.razem AT siol.net>
12269 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12271 2002-08-10 Borut Razem <borut.razem AT siol.net>
12272 * src/SDCCmain.c (main):
12273 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12274 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12275 The consequence was that some temporary files were not removed.
12278 unification of code in functions tempfilename() and tempfile():
12279 function tempnam() is defined in Visual Studio 6.0 and .NET
12281 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12283 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12284 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12285 - removed compiler command line option /WX: Treats all warnings as errors
12286 - update a list of source files, included into the project
12288 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12289 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12290 changed project type to Generic Project so that can be correcly converted to VS.NET project
12292 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12294 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12296 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12298 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12299 added return 0 statements after assert() to make compiler happy
12301 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12302 added newline in the def file to keep MSC compiler satisfied
12304 * sdcc/src/z80/gen.c:
12305 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12306 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12307 - solved MSC error in function aopDump()
12309 * sdcc_vc.h: define PREFIX as "\\sdcc"
12311 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12312 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12315 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12316 - Rewrote the register banking algorithm.
12317 - Added pCode live-range analysis to registers (for now, only non-used and
12318 singly-used registers optimized away)
12320 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12322 * 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.

12347 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
12349 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12351 2002-03-28 Johan Knol <johan AT balder>
12353 * src/SDCCval.c: fixed bug #532436
12355 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12357 Added "char *Processor" field to the port structure.
12360 Added -p option. Allows port dependent processor to be specified.
12363 Initialized the new field char *Processor field to NULL in all ports
12366 Compiler generated registers for interrupt context saving
12367 were not getting allocated.
12369 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12372 Fixed left shift. Will promote the left side of a left shift
12373 if a) left shifting more than size of operand or b) when assigned
12374 to something size > size of left side
12376 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12378 tons of changes. Register allocation has been
12379 rewritten. Added customization for the various PICs. Flow
12380 analysis is restructured. ...
12382 * src/pic/device.h:
12385 * src/pic/device.c:
12386 Added. device.c is a PIC port hack to accomodate variations
12389 2002-03-13 Michael Hope <michaelh AT vroom>
12391 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
12393 2002-03-04 johanknol <johanknol AT manik>
12395 * /src/SDCCval.c: fixed
12397 const unsigned char arr[][2] = { { 0, 1 } };
12398 t18.c:1: error: Initializer element is not constant
12400 2002-03-04 bela <bela AT manik>
