2237 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2239 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2240 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2242 One basic decision: e.g. src/clean.mk includes further files. In order
2243 to make this work there are two solutions:
2244 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2245 run configure on them. This way they can use
2246 'include $(srcdir)/port-clean.mk'
2247 - always include clean.mk by the Makefile at the same level. To avoid
2248 that `make clean` tries to include and build Makefile.dep the
2249 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2250 implemented, because now even `make uninstall` doesn't create
2251 Makefile.in. clean.mk could be eliminated by pasting it in
2254 * debugger/mcs51/Makefile.in: build own objects from library sources
2255 (SLIB, SDCC) in current directory
2257 * configure, configure.in: renamed --disable-device-lib-build in
2258 --disable-device-lib; added --enable-doc, the required tools are
2259 searched by configure; added result message; the toolchain for the
2260 belonging ports are now only built, if the port is enabled.
2262 * support/regression/*: all output is written in directory gen, because
2263 the fwk and ports directories don't livet in the build tree using vpath
2265 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2266 --disable-device-lib, added --enable-doc, added section VPATH
2268 * sim/ucsim/configure.in,
2269 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2270 z80 are enabled by default
2272 2006-04-24 Raphael Neider <rneider AT web.de>
2274 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2275 to config word, "pic14_"-prefixed some extern functions
2276 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2277 config word has been found
2278 * src/pic/device.h: added prototypes
2279 * src/pic/pcode.c: added "pic14_"-prefix where needed
2280 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
2282 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2296 fixes #1469504 and #1474602,
2297 (pCodeRegOptimizeRegUsage): fixed typo in comment

2565 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2567 * src/.version: increased version number to 2.5.5
2568 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2569 linking is done manually in pic16 port's _linkEdit,
2570 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2571 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

2587 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2588 call to allocReg, not by manually allocating a new one,
2589 (pic16_assignRegisters): now before going through the register
2590 allocating functions mark all registers as free. This eliminates some
2591 side effects resulting from peephole parser done earlier in the backbone
2593 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2653 the number of the local variables used by the specified function, added
2654 'xinst' for initial support for Extended Instruction Support,
2655 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2656 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2657 port->fun_prefix anymore (may change later),

2673 (commented out for reference), didn't account for some registers which
2674 were left marked 'not free' after a pointer operation. The change
2675 reduces register usage a lot in some cases

4952 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4953 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4954 always available in leading double underscore form. The C99 support is

5033 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
5035 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
5037 * device/lib/printf_large.c: removed inline assembly for portability and
5038 readability. Use printf_fast if speed or size are more important.
5039 * src/pic16/gen.c: removed conditions around use of DEBUGpc
5040 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
5042 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
5044 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
5045 prevent compiler warning
5047 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
5049 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
5050 moved to level 0 and declared as static. Also they are explicit
5051 placed in access bank. This was necessery because some times they
5052 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
5053 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
5054 optimizations. Currently only compare to unsigned char is implemented,
5055 * src/pic16/gen.c: added fReturnIdx array,
5056 * (struct resolvedIfx) is moved to gen.h and made public,
5057 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5058 * (aopForSym): added an optimization to directly store in stack of
5059 the operand of a SEND iCode,
5060 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5061 but as registers instead (AOP_REG) using the fReturnIdx array,
5062 * (pic16_freeAsmop): remove the freed register from the
5063 _G.sregsAlloc field,
5064 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5065 a compare of 'WREG',
5066 * (pic16_popGetTempRegCond): changed function prototype, now
5067 function takes also a bitVector argument v which holds the current
5068 set of registers that are allocated for stack access by aopForSym,
5069 registers allocated in aopForSym for accessing stack symbols are not
5070 any more part of the functions usedRegs field,
5071 * (genCall): some times aopOp is called for a stack variable to be
5072 send, aopForSym might perform the push, if this is true make sure
5073 that genCall doesn't push the variable twice by testing _G.resDirect,
5074 * (genFunction): changed testing for unspecified interrupt number
5075 from 256 to INTNO_UNSPEC,
5076 * modified selection scheme of frame pointer generation. Previously
5077 if function did use local registers a frame pointer was generated,
5078 now a frame pointer is generated only if function has arguments
5079 (that need PLUSW2 register access), or has stack arguments, or the
5080 compiler is not instructed to omit the frame pointer,
5081 * (genEndFunction): before restoring local registers that were saved
5082 in the function preamble, also restore the registers that *might*
5083 have been allocated for stack access,
5084 * (genRet): removed some old comments,
5085 * (genCmp, the active (RN's) version): added a call to the
5086 pic16_genCmp_special function to perform the compare with a more
5087 robust and optimized way,
5088 * (genInline): a feature has been added in inline code generation,
5089 which allows a wildcard variable substitution when writing inline
5090 assembly. Code is incomplete and experimental therefore undocumented,
5091 * (genCast): changed order of aopOp for result and right to allow
5092 aopForSym to directly load the result if possible,
5093 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5094 perform an optimized compare on some selected special occasions,
5095 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5096 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5097 generate an IVT any more,
5098 * src/pic16/main.c (pic16_optionsTable): added command line option
5100 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5101 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5103 * src/pic16/NOTES: Raphael Neider added in list of active developers
5104 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5105 jumptable_end to prevent bug #,
5106 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5107 inCond and outCond fields,
5108 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5109 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5110 turn off register spilling,
5111 * (packRegsForOneUse): synced with other ports' versions although it
5112 is not used currently,
5113 * (pic16_packRegisters): added an optimization while reading
5114 structure bitfields, some registers may be saved (malloc code is
5115 decreased by 80 bytes)
5117 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5119 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5120 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5121 this can be optimized more?
5123 2005-03-10 Raphael Neider <rneider AT web.de>
5125 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5126 genNearPointerGet): (hopefully) fixed access to bitfields via
5127 pointers (p->bitN = x; and x = p->bitN; failed)
5129 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
5131 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
5133 2005-03-09 Raphael Neider <rneider AT web.de>

5761 Adding support for replacing ljmps with sjmps in jumptables
5762 generated for switch statements. For now you need to set the
5763 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5764 Now 4 algorithms for mcs51 jumptable generation are used:
5765 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5766 addresses loaded pc-relative for up to 112 cases and stack-pushing
5767 target addresses loaded with offset from dptr for up to 256 cases.

5797 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5799 * added libc directory. The current version of LibC contains string
5800 functions, ctype functions and macros and some functions of the
5801 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5802 be extensively tested in the future. Standard disclaimer here.
5803 Library is not automatically build yet. But one can build it by
5804 invoking 'make' inside the libc directory.

5815 * (pic16_storeForReturn): optimized return of 0,
5816 * (genCmp): experimental code for new genCmp which uses PIC18's
5817 special compare&skip instructions. Initial tests fail some times
5818 with variables grater than 1 byte in size, so new code is disabled,
5819 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5821 * (genCast): began a fix to optimize the casting of a bit to another
5822 bit, now assigning a bitfield to another bitfield will fail, sorry,

5830 * (isBankInstruction): modified to return 0 for no banking instruction,
5831 and 1 for banking instruction,
5832 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5833 caused stop processing pCodes after a inline assembly block,
5834 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5835 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5836 registers when it shouldn't,
5837 * src/pic16/ralloc.c (allocReg): add preliminary support for
5838 supporting a limited set of temporary registers,
5840 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5842 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

5846 (genFunction): optimize RECEIVE iCodes in reentrant functions
5848 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8848 loaded with the linker search paths (-L arguments) and the libraries
8849 to be linked with the current source (-l arguments). Changes
8850 currently will affect only the pic16 port.
8851 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8852 include path the port specific paths and port specific libraries,
8853 * gplink command now contains the $3 argument,
8854 * src/pic16/device.h,

8871 Documenting changes from previous commits.
8872 * configure.in (version 1.56),
8873 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8874 when generating output files to configure the pic16 library,
8875 but now I've commented it out, since gputils aren't installed in the
8876 SF compile farm, so library won't compile
8878 * device/lib/Makefile.in (version 1.56): initially I've added in
8879 target 'all' the prerequestive 'model-pic16' so it compiled the
8880 pic16 library, but now I've commented it out for the same reasons
8882 * added targets 'model-pic16' and 'objects-pic16' to compile the
8884 * added target 'port-specific-objects-pic16' to handle the
8885 generated libraries and copy them into the build/ directory
8886 * added target 'clean-intermediate-pic16' to clean intermediate
8887 files into pic16 directory
8888 * in target 'installdirs' added line to create directory pic16 in

9142 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9144 A python script to validate compiler diagnostic messages. It can be
9145 used to verify that sdcc complains about bad c source code and
9146 gives a good location of the error.
9147 * support/valdiag/Makefile,
9148 * support/valdiag/valdiag.py,
9149 * support/valdiag/tests/*
9151 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9153 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
9154 * src/SDCCsymt.c (newEnumType),
9156 * support/Util/SDCCerr.c,
9157 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
9159 * support/regression/tests/enum.c: added test for enum values that
9160 require at least 2 bytes of storage.
9162 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9164 * src/common.h: added ifndef/define/endif macros
9165 around the header file.
9166 Bug reported from Jesus Calvino-Fraga
9168 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
9170 * sdcc.spec: updated
9171 * device/include/Makefile.in: don't install CVS directories
9172 * device/lib/Makefile.in: added removal of CVS directories after install
9173 * doc/Makefile: fixed install, added local_icons
9174 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
9175 * src/mcs51/gen.c (genRightShift): fixed bug #870788
9176 * src/ds390/gen.c (genRightShift): fixed bug #870788
9177 * src/SDCCast.c (decorateType): fixed bug #870781
9179 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9181 PIC16 port related changes:
9182 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9183 added variable stackPos,
9185 * gen.c: genCall, assignResultValue: added support for
9186 pushing/retrieving function parameters to/from stack,
9187 genFunction,genEndFunction: setup stack frame for the
9189 genAddrOf: will be changed according to bug 863624
9191 * added files genutils.c and genutils.h which contain gen*
9192 debugged and optimised functions extracted from gen.c
9194 * glue.c: added variable 'externs' which holds extern symbols,
9195 pic16emitRegularMap: is modified to properly handle relocatable
9196 symbols under the new scheme,
9197 pic16createInterruptVect: is modified
9198 pic16printPublics: is modified to emit 'global' assembler directives,
9199 added pic16_printExterns to print extern symbols,
9200 pic16glue: initializes stack/frame pointer in the beginning of
9201 the assembly output. Temporary hack, will be corrected later,
9202 because gplink yet does not support stack and SDCC does not
9203 yet support a type of crt0.o object to create the final binary.
9205 * Removed many lines that contain 8051 legacy code.
9206 * The code is finally placed under a 'code' directive.
9207 * Added port specific options.
9209 * _process_pragma: simplified since now we do not need *special*
9210 include file to define SFR registers. But a separate header
9211 will be needed. This will be developed later.
9212 * _pic16_parseOptions: added, parses port specific options:
9213 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9214 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9215 --preplace-udata-with=
9217 * _pic16_setDefaultOptions: modified to initialize section names,
9218 but hack is temporarly out of order since it needs improvement.
9219 * _pic16_genAssemblerPreamble: configuration words are emitted by
9220 their address instead of their name. This part is incomplete and
9221 supports only the 18Fxx2 devices. Other devices will emit an error
9222 during assembly since they do not contain the same set of config
9224 * _pic16_genIVT: is modified,
9226 * pcode.c: added definitions for some hardware registers that are needed
9228 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9229 All PCI entries are updated. Now LFSR is supported.
9230 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9231 * added pic16_newpCodeOpLit2 to support instructions with
9232 two literal arguments
9233 * pic16_pCode2str: corrected code that emits assembler instructions
9234 with two literal operands and those that have an access bit modifier
9235 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9236 this fixes a bug which caused some labels to be lost, when an
9237 assembler directive was added, i.e. banksel,
9238 * pic16_FixRegisterBanking: improved logic that causes the insertion
9240 * InlineFunction: functions that are called once, are not any more
9241 inlined. This can be a port option in the future,
9243 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9245 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9246 hold the corresponding uninitialized symbols,
9247 * pic16_allocProcessorRegister: registers have explicit marked the
9249 * pic16_allocInternalRegister: registers are explicit marked as
9251 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9252 processing list, so bit registers were lost,
9255 * ralloc.h: added field 'accessBank' and original symbol operand
9256 in register definition,
9257 * removed the field isMapped from register definition,
9259 ** Several functions have been removed from various sources:
9260 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9261 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9262 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9263 pic16_assignRelocatableRegisters
9265 ** others have been introduced:
9266 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9267 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9269 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9271 * support/scripts/inc2h.pl: changed definition of BIT_AT
9272 to emit 'sbit at' instead of 'bit at'. This was a request.
9274 PIC16 port related preliminary changes:
9275 * gen.c: prefixed function popRegFromString with
9276 pic16_ and all references to it corrected
9277 * pcode.c: all pic16_pc_* hardware registers prefixed
9278 with underscore (_),
9279 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9280 * ralloc.c: newReg(): when register is REG_SFR then
9281 set address to rIdx,
9282 pic16_allocProcessorRegister(): marks register wasUsed=0
9283 pic16_writeUsedRegs(): added a call to assign processor
9284 registers via pic16_assignFixedRegisters
9286 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9288 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9289 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9290 variables in unused register banks. Also the SSEG is placed
9291 wherever there is enough space for it, and IDATA can be anywhere
9292 in internal RAM. For now compile using -Wl-Y[stack_size].
9293 The mem file is different for this option as well, since it
9294 makes no sense of talking about DSEG lenght.
9296 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9298 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9299 in certain cases, e.g. when ROM assignment, patch provided
9300 from Albert den Haan.
9302 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9445 * src/mcs51/peephole.def,
9446 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
9447 (allows non-interrupt and interrupt code to safely compete for a resource

9458 multiply defined with mismatching "at" address.
9460 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9462 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

9541 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9543 * src/SDCCast.c (decorateType): disabled a transformation I added in
9544 revision 1.188 (access to fields of a structure at an absolute address);
9545 it breaks with bitfields, extern declarations, and gcse analysis.
9546 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9547 could be assigned through a pointer, so don't complain.
9548 * src/SDCCast.c (astErrors),
9550 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

10130 genCodePointerGet, genGenPointerGet, genFarPointerSet,
10131 genGenPointerSet): handle AOP_DPTR correctly when loading dptr
10132 (ralloc doesn't intentionally do this now, but perhaps later)
10133 * src/mcs51/ralloc.c (serialRegAssign, fillGaps),
10134 * src/ds390/ralloc.c (serialRegAssign, fillGaps): fixed some

10146 2003-09-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10148 * src/SDCCsymt.c (structElemType): fixed bug #808291 (members
10149 of const struct should be treated as if const themselves)
10151 2003-09-18 Bernhard Held <bernhard AT bernhardheld.de>
10153 * src/SDCCval.c (valPlus, valMinus): fixed bug #808337

10168 * src/ds390/gen.c (genFunction, genEndFunction): Moved save
10169 and restore of EA so that stack offsets to parameters are
10170 correct when using both critical and reentrant/stack-auto.
10171 * src/z80/gen.c (aopOp): removed erroneous assertion about sloc
10172 size (can be triggered in error if sloc is shared between
10173 different sized objects)
10174 * device/include/float.h: fixed macros to explicitly use
10175 unsigned long where needed
10177 2003-09-15 Bernhard Held <bernhard AT bernhardheld.de>

10185 * src/SDCCsymt.c (sclsFromPtr),
10187 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
10188 support for standard C idiom of memory mapped variables; for
10189 example, *((xdata int*)0x1234) = 1 is now internally equivalent
10190 to xdata int at 0x1234 tempvar = 1.
10191 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
10192 provided by Akiya ISHIDA

10208 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10210 Fixed bug #621531 (const & volatile confusion in the type chain).
10211 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
10212 refer to the const or volatile state of the pointer itself.

10282 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
10284 * device/lib/_mullong.c: replaced int by short for gcc
10286 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10288 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
10289 and JUMPTABLE iCodes properly now (worked by accident before)
10290 * src/mcs51/gen.c (leftRightUseAcc),
10291 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10292 iCode properly now. Use getSize instead of nRegs since a & b
10293 aren't part of the nRegs tally.
10295 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10297 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10303 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
10304 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
10305 fetching of the pointer
10306 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
10307 copied from genNearPointerSet()
10308 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10309 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10310 If they pop r0/r1 they must be called in the opposite order than aopOp().
10311 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10312 (resp. --stack-auto), prepared for --xstack
10314 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10316 * doc/sdccman.lyx: reverted tables to those in cvs 1.64
10318 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10320 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
10321 these ports have their own __sdcc_external_start()
10323 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10325 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10326 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10327 type for bits was changed. It resulted in bit variables becoming
10328 global, which is not permitted in PIC 14 assembly output.
10330 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10332 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10334 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10336 Z80 and MCS51 linkers complaint if a public symbol is defined
10337 in more than one library module:

10343 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10345 A few small changes that speed up the peephole optimizer.
10349 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10351 Try to make the peephole optimizer smarter by maintaining
10352 an association between the assembly source code and the
10353 iCodes that originated them. Put this information to use
10354 with a new peephole rule condition "notVolatile" so that
10355 the rules can be aggressive yet still safe.
10360 * src/mcs51/peeph.def
10362 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10366 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10367 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10368 if the left or right operand symbols have the accuse flag set.
10370 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10372 Changed the type of the result of the ! (NOT) operator to char;
10373 previously it returned the same type as the source. This allows
10374 us to eliminate all the genFloatNot functions (all of its target
10375 implementations were very buggy) since !float can use the same
10378 * src/SDCCicode.c (ast2iCode): ! returns char
10379 * src/mcs51/gen.c (genNot, genNotFloat),
10380 * src/ds390/gen.c (genNot, genNotFloat),
10381 * src/z80/gen.c (genNot, genNotFloat),
10382 * src/pic/gen.c (genNot, genNotFloat),
10383 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

10387 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10388 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10389 during interrupts. Ensure WSAVE is located at a shared bank address.
10390 2. Fixed page selection in some places
10391 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10392 the registers name strings.
10393 4. Fixed "signed / unsigned compare" compiler warnings.
10394 5. The PIC port manages its own allocation of the general purpose
10395 registers, but makes no attempt to reuse them. As a result when
10396 compiling it soon runs out of general purpose registers. Some
10397 additional code was added to the files pcode.c and device.c to walk
10398 through the function call tree and rename the registers so that they
10408 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10409 genPlus() & genMinus() when the result is the same as left or right
10411 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10415 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10417 Made bitfield a distinct type from bit so that bitfields
10418 convert as per ANSI C and bits retain their traditional
10419 boolean style behaviour. Implemented bitfield support in
10427 * src/ds390/gen.c: bit v bitfield split
10428 * src/z80/gen.c: New support for bitfields
10429 * support/regression/tests/bitfields.c: reenabled z80,
10432 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10434 Rules 246.x, 247.x relate to bitfields, the others speed up
10435 access to xdata mapped I/O devices.
10437 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10439 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10441 Cleaned up genPackBits and genUnpackBits and added two helper
10442 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10443 for literal assignments in genPackBits (thanks to Frieder for
10449 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10451 Fixed bug #748310 (pointer to function type mishandled when the
10452 function name is omitted). Also fixed a SIGSEGV when a function
10453 attribute (reentrant, etc) is used on a non-function or on a
10454 function but misplaced before the parameter list.
10456 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10458 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10459 * support/Util/SDCCerr.h,
10460 * support/Util/SDCCerr.c: Added func attr misuse error msg
10462 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10464 Fixed bug #787649 by anonymous
10465 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10466 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10468 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10470 Fixed numerous bitfield problems.
10472 * src/SDCC.y: More bitfield related error checking

10475 * support/Util/SDCCerr.h,
10476 * support/Util/SDCCerr.c: Added & edited some bitfield err msgs
10477 * src/mcs51/gen.c (genPackBits, genUnpackBits): fixed mask bugs
10478 * src/ds390/gen.c (genPackBits, genUnpackBits): fixed mask bugs
10479 * support/regression/tests/bitfields.c: tests added
10481 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10483 Made the constant following the "interrupt" keyword optional. If
10484 omitted, the function will not automatically be given an entry
10485 in the interrupt vector table (similar to #pragma NOIV, but
10486 less syntacticly kludgy). The interrupt number is also now
10487 range checked. Also fixed a bug in the high order bit example

10495 * support/Util/SDCCerr.h
10498 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10500 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
10501 * src/SDCCicode.c (operandOperation): rewritten some ops
10502 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
10503 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10505 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10506 be re-activated by defining REDUCE_LITERALS)
10507 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10508 unsigned, but are signed by default
10509 * src/SDCCval.c (constVal): rearranged
10510 * src/SDCCval.c (valMod): preliminary fix
10511 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10551 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10552 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10553 constants are unsigned; added recognition of "u" flag for unsigned
10554 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10555 * src/SDCCval.c (valDiv, valMod): fixed signdness

11019 support for the PIc16 port in the ports table, when executing
11020 the compiler with no port specified on command line, a default
11021 port is selected with the new macro DEFAULT_PORT which is
11022 defined in port.h, in setDefaultOptions() linkOptions is removed
11023 from initialization assignment, since now it is a set,
11024 parseCmdLine uses setParseWithComma for linkOptions, in
11025 linkEdit() linkOptions are accessed with new function indexSet()
11026 which returns the i'th item of a set variable. See SDCCset.c, in
11027 linkEdit() when calling buildCmdLine(), added linkOptions as
11028 last argument. Now users can pass arguments to gplink via the

11043 gpasm complaining and test the linkage with gplink, _linkCmd and
11044 _asmCmd changed to be more gplink and gpasm friendly
11045 * src/pic16/peeph.def: peep rule 3 is commented out, since it
11046 produced an error when parsed, peep rule 12 is added to utilize
11047 movff, but it is commented out since the pCode does not support
11048 yet a command with 2 address arguments

12110 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12111 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12113 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12115 * in /sdcc/as/mcs51/ changed these files in order to create an
12116 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12117 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12118 following files to include the previous two files: aslink.dsp,
12119 Makefile.aslink, Makefile.bcc, and Makefile.in.
12121 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12122 .adb instead of .cdb
12124 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12126 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12127 value from option --iram-size.
12129 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12131 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12134 2002-09-18 <wiml AT hhhh.org>
12136 * SDCClrange.h: exposed setFromRange() and setToRange()
12137 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12138 packRegsForAccUse() (bug 542397)
12139 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12140 multiple times and emitting the fetch operations more than once
12141 added aopGetUsesAcc() function to allow binary operators to
12142 fetch their operands in the correct order; made genMinus() emit
12143 compact code for X = LITERAL - Y
12145 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12146 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12147 sprintf() in line 1267.
12149 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12150 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12153 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12154 Changes to aslink (All the changes are marked with 'JCF'):
12156 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12159 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12160 area BSEG. Also moves, if possible, the DATA area down into the internal
12161 ram so more space is available.
12163 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12166 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12167 not bytes. Function summary() which creates a memory usage summary
12168 file with extension .mem. Reports of overlaping stack and small stack
12169 size. If the space for the stack is less than 16 bytes aslink trows a
12172 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12173 the 8051. Option 'y' for memory summary output file.
12175 Changes to sdcc (All the changes are marked with 'JCF'):
12177 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12179 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12180 overlaying area for it (uses RegBankUsed[4]).
12182 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12183 bank zero as used by default. By default aslink locates the stack
12184 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12185 the creation of the .mem file. Delegates the allocation of data area
12186 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12187 the begining of the stack area to aslink.
12189 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12190 glue() in SDCCglue.c creates an area for it.
12192 2002-09-03 Borut Razem <borut.razem AT siol.net>
12193 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12194 sdcc/src/pic/glue.c:
12195 introduced atexit() handler for teporay files removal in case of
12196 errors, assertions, ...
12198 2002-08-29 Borut Razem <borut.razem AT siol.net>
12199 * sdcc/support/cpp2/auto-host_vc_in.h:
12200 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12201 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12202 Maybe there is a similar problem with BORLANDC? It should be checked!
12204 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12205 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12206 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12207 was not executed, and the compiler (cl) launched a warning:
12208 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12210 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12211 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12213 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12214 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12216 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12217 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12218 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12219 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12220 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12221 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12222 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12223 - added Release configuration in VS projects
12224 - review of compiler an linker options
12225 - VC .exe files are generated in bin_vc directory, not to interfere
12226 with binaries generated from other projects (cygwin, mingw, bcc ...)
12228 * sdcc/src/yacc.dsp: added
12230 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12231 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12232 and insert the version number definitions from .version
12234 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12236 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12237 added - genarate auto-host.h using auto-host_vc_in.h as template
12240 removed from CVS, generated automatically
12242 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12243 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12245 2002-08-11 Borut Razem <borut.razem AT siol.net>
12246 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12248 2002-08-10 Borut Razem <borut.razem AT siol.net>
12249 * src/SDCCmain.c (main):
12250 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12251 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12252 The consequence was that some temporary files were not removed.
12255 unification of code in functions tempfilename() and tempfile():
12256 function tempnam() is defined in Visual Studio 6.0 and .NET
12258 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12260 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12261 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12262 - removed compiler command line option /WX: Treats all warnings as errors
12263 - update a list of source files, included into the project
12265 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12266 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12267 changed project type to Generic Project so that can be correcly converted to VS.NET project
12269 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12271 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12273 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12275 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12276 added return 0 statements after assert() to make compiler happy
12278 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12279 added newline in the def file to keep MSC compiler satisfied
12281 * sdcc/src/z80/gen.c:
12282 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12283 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12284 - solved MSC error in function aopDump()
12286 * sdcc_vc.h: define PREFIX as "\\sdcc"
12288 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12289 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

12292 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12293 - Rewrote the register banking algorithm.
12294 - Added pCode live-range analysis to registers (for now, only non-used and
12295 singly-used registers optimized away)
12297 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12299 * 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.

12326 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12328 2002-03-28 Johan Knol <johan AT balder>
12330 * src/SDCCval.c: fixed bug #532436
12332 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12334 Added "char *Processor" field to the port structure.
12337 Added -p option. Allows port dependent processor to be specified.
12340 Initialized the new field char *Processor field to NULL in all ports
12343 Compiler generated registers for interrupt context saving
12344 were not getting allocated.
12346 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12349 Fixed left shift. Will promote the left side of a left shift
12350 if a) left shifting more than size of operand or b) when assigned
12351 to something size > size of left side
12353 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12355 tons of changes. Register allocation has been
12356 rewritten. Added customization for the various PICs. Flow
12357 analysis is restructured. ...
12359 * src/pic/device.h:
12362 * src/pic/device.c:
12363 Added. device.c is a PIC port hack to accomodate variations
12366 2002-03-13 Michael Hope <michaelh AT vroom>
12368 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
12370 2002-03-04 johanknol <johanknol AT manik>
12372 * /src/SDCCval.c: fixed
12374 const unsigned char arr[][2] = { { 0, 1 } };
12375 t18.c:1: error: Initializer element is not constant
12377 2002-03-04 bela <bela AT manik>
