2066 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2068 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2070 * device/lib/printf_large.c: removed inline assembly for portability and
2071 readability. Use printf_fast if speed or size are more important.
2072 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2073 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2075 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2077 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2078 prevent compiler warning
2080 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2082 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2083 moved to level 0 and declared as static. Also they are explicit
2084 placed in access bank. This was necessery because some times they
2085 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2086 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2087 optimizations. Currently only compare to unsigned char is implemented,
2088 * src/pic16/gen.c: added fReturnIdx array,
2089 * (struct resolvedIfx) is moved to gen.h and made public,
2090 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2091 * (aopForSym): added an optimization to directly store in stack of
2092 the operand of a SEND iCode,
2093 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2094 but as registers instead (AOP_REG) using the fReturnIdx array,
2095 * (pic16_freeAsmop): remove the freed register from the
2096 _G.sregsAlloc field,
2097 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2098 a compare of 'WREG',
2099 * (pic16_popGetTempRegCond): changed function prototype, now
2100 function takes also a bitVector argument v which holds the current
2101 set of registers that are allocated for stack access by aopForSym,
2102 registers allocated in aopForSym for accessing stack symbols are not
2103 any more part of the functions usedRegs field,
2104 * (genCall): some times aopOp is called for a stack variable to be
2105 send, aopForSym might perform the push, if this is true make sure
2106 that genCall doesn't push the variable twice by testing _G.resDirect,
2107 * (genFunction): changed testing for unspecified interrupt number
2108 from 256 to INTNO_UNSPEC,
2109 * modified selection scheme of frame pointer generation. Previously
2110 if function did use local registers a frame pointer was generated,
2111 now a frame pointer is generated only if function has arguments
2112 (that need PLUSW2 register access), or has stack arguments, or the
2113 compiler is not instructed to omit the frame pointer,
2114 * (genEndFunction): before restoring local registers that were saved
2115 in the function preamble, also restore the registers that *might*
2116 have been allocated for stack access,
2117 * (genRet): removed some old comments,
2118 * (genCmp, the active (RN's) version): added a call to the
2119 pic16_genCmp_special function to perform the compare with a more
2120 robust and optimized way,
2121 * (genInline): a feature has been added in inline code generation,
2122 which allows a wildcard variable substitution when writing inline
2123 assembly. Code is incomplete and experimental therefore undocumented,
2124 * (genCast): changed order of aopOp for result and right to allow
2125 aopForSym to directly load the result if possible,
2126 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2127 perform an optimized compare on some selected special occasions,
2128 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2129 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2130 generate an IVT any more,
2131 * src/pic16/main.c (pic16_optionsTable): added command line option
2133 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2134 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2136 * src/pic16/NOTES: Raphael Neider added in list of active developers
2137 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2138 jumptable_end to prevent bug #,
2139 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2140 inCond and outCond fields,
2141 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2142 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2143 turn off register spilling,
2144 * (packRegsForOneUse): synced with other ports' versions although it
2145 is not used currently,
2146 * (pic16_packRegisters): added an optimization while reading
2147 structure bitfields, some registers may be saved (malloc code is
2148 decreased by 80 bytes)
2150 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2152 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2153 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2154 this can be optimized more?

2794 Adding support for replacing ljmps with sjmps in jumptables
2795 generated for switch statements. For now you need to set the
2796 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2797 Now 4 algorithms for mcs51 jumptable generation are used:
2798 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2799 addresses loaded pc-relative for up to 112 cases and stack-pushing
2800 target addresses loaded with offset from dptr for up to 256 cases.

2830 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2832 * added libc directory. The current version of LibC contains string
2833 functions, ctype functions and macros and some functions of the
2834 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2835 be extensively tested in the future. Standard disclaimer here.
2836 Library is not automatically build yet. But one can build it by
2837 invoking 'make' inside the libc directory.

2848 * (pic16_storeForReturn): optimized return of 0,
2849 * (genCmp): experimental code for new genCmp which uses PIC18's
2850 special compare&skip instructions. Initial tests fail some times
2851 with variables grater than 1 byte in size, so new code is disabled,
2852 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2854 * (genCast): began a fix to optimize the casting of a bit to another
2855 bit, now assigning a bitfield to another bitfield will fail, sorry,

2864 and 1 for banking instruction,
2865 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2866 caused stop processing pCodes after a inline assembly block,
2867 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

2869 registers when it shouldn't,
2870 * src/pic16/ralloc.c (allocReg): add preliminary support for
2871 supporting a limited set of temporary registers,
2873 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

2879 (genFunction): optimize RECEIVE iCodes in reentrant functions
2881 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5881 loaded with the linker search paths (-L arguments) and the libraries
5882 to be linked with the current source (-l arguments). Changes
5883 currently will affect only the pic16 port.
5884 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5885 include path the port specific paths and port specific libraries,
5886 * gplink command now contains the $3 argument,

5904 Documenting changes from previous commits.
5905 * configure.in (version 1.56),
5906 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5907 when generating output files to configure the pic16 library,
5908 but now I've commented it out, since gputils aren't installed in the
5909 SF compile farm, so library won't compile
5911 * device/lib/Makefile.in (version 1.56): initially I've added in
5912 target 'all' the prerequestive 'model-pic16' so it compiled the
5913 pic16 library, but now I've commented it out for the same reasons
5915 * added targets 'model-pic16' and 'objects-pic16' to compile the
5917 * added target 'port-specific-objects-pic16' to handle the
5918 generated libraries and copy them into the build/ directory
5919 * added target 'clean-intermediate-pic16' to clean intermediate
5920 files into pic16 directory
5921 * in target 'installdirs' added line to create directory pic16 in
5922 the installation path

5925 added lines to copy all header files to installation path,
5926 * in target 'installdirs' added line create directory for pic16
5927 headers in the installation path

6161 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6163 * src/SDCCval.c (valShift): changed from 16 to 32 bit shift count,
6165 * support/valdiag/tests/overflow.c: added
6166 * src/SDCCast.c (decorateType),
6167 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
6168 LEFT_OP (left shift)
6170 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6172 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6173 (default behaviour).
6175 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6177 A python script to validate compiler diagnostic messages. It can be
6178 used to verify that sdcc complains about bad c source code and
6179 gives a good location of the error.
6180 * support/valdiag/Makefile,
6181 * support/valdiag/valdiag.py,
6182 * support/valdiag/tests/*
6184 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6186 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
6187 * src/SDCCsymt.c (newEnumType),
6189 * support/Util/SDCCerr.c,
6190 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
6192 * support/regression/tests/enum.c: added test for enum values that
6193 require at least 2 bytes of storage.
6195 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6197 * src/common.h: added ifndef/define/endif macros
6198 around the header file.
6199 Bug reported from Jesus Calvino-Fraga
6201 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6203 * sdcc.spec: updated
6204 * device/include/Makefile.in: don't install CVS directories
6205 * device/lib/Makefile.in: added removal of CVS directories after install
6206 * doc/Makefile: fixed install, added local_icons
6207 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6208 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6209 * src/ds390/gen.c (genRightShift): fixed bug #870788
6210 * src/SDCCast.c (decorateType): fixed bug #870781
6212 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6214 PIC16 port related changes:
6215 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6216 added variable stackPos,
6218 * gen.c: genCall, assignResultValue: added support for
6219 pushing/retrieving function parameters to/from stack,
6220 genFunction,genEndFunction: setup stack frame for the
6222 genAddrOf: will be changed according to bug 863624
6224 * added files genutils.c and genutils.h which contain gen*
6225 debugged and optimised functions extracted from gen.c
6227 * glue.c: added variable 'externs' which holds extern symbols,
6228 pic16emitRegularMap: is modified to properly handle relocatable
6229 symbols under the new scheme,
6230 pic16createInterruptVect: is modified
6231 pic16printPublics: is modified to emit 'global' assembler directives,
6232 added pic16_printExterns to print extern symbols,
6233 pic16glue: initializes stack/frame pointer in the beginning of
6234 the assembly output. Temporary hack, will be corrected later,
6235 because gplink yet does not support stack and SDCC does not
6236 yet support a type of crt0.o object to create the final binary.
6238 * Removed many lines that contain 8051 legacy code.
6239 * The code is finally placed under a 'code' directive.
6240 * Added port specific options.
6242 * _process_pragma: simplified since now we do not need *special*
6243 include file to define SFR registers. But a separate header
6244 will be needed. This will be developed later.
6245 * _pic16_parseOptions: added, parses port specific options:
6246 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6247 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6248 --preplace-udata-with=
6250 * _pic16_setDefaultOptions: modified to initialize section names,
6251 but hack is temporarly out of order since it needs improvement.
6252 * _pic16_genAssemblerPreamble: configuration words are emitted by
6253 their address instead of their name. This part is incomplete and
6254 supports only the 18Fxx2 devices. Other devices will emit an error
6255 during assembly since they do not contain the same set of config
6257 * _pic16_genIVT: is modified,
6259 * pcode.c: added definitions for some hardware registers that are needed
6261 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6262 All PCI entries are updated. Now LFSR is supported.
6263 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6264 * added pic16_newpCodeOpLit2 to support instructions with
6265 two literal arguments
6266 * pic16_pCode2str: corrected code that emits assembler instructions
6267 with two literal operands and those that have an access bit modifier
6268 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6269 this fixes a bug which caused some labels to be lost, when an
6270 assembler directive was added, i.e. banksel,
6271 * pic16_FixRegisterBanking: improved logic that causes the insertion
6273 * InlineFunction: functions that are called once, are not any more
6274 inlined. This can be a port option in the future,
6276 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6278 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6279 hold the corresponding uninitialized symbols,
6280 * pic16_allocProcessorRegister: registers have explicit marked the
6282 * pic16_allocInternalRegister: registers are explicit marked as
6284 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6285 processing list, so bit registers were lost,
6288 * ralloc.h: added field 'accessBank' and original symbol operand
6289 in register definition,
6290 * removed the field isMapped from register definition,
6292 ** Several functions have been removed from various sources:
6293 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6294 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6295 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6296 pic16_assignRelocatableRegisters
6298 ** others have been introduced:
6299 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6300 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6302 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6304 * support/scripts/inc2h.pl: changed definition of BIT_AT
6305 to emit 'sbit at' instead of 'bit at'. This was a request.
6307 PIC16 port related preliminary changes:
6308 * gen.c: prefixed function popRegFromString with
6309 pic16_ and all references to it corrected
6310 * pcode.c: all pic16_pc_* hardware registers prefixed
6311 with underscore (_),
6312 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6313 * ralloc.c: newReg(): when register is REG_SFR then
6314 set address to rIdx,
6315 pic16_allocProcessorRegister(): marks register wasUsed=0
6316 pic16_writeUsedRegs(): added a call to assign processor
6317 registers via pic16_assignFixedRegisters
6319 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6321 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6322 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6323 variables in unused register banks. Also the SSEG is placed
6324 wherever there is enough space for it, and IDATA can be anywhere
6325 in internal RAM. For now compile using -Wl-Y[stack_size].
6326 The mem file is different for this option as well, since it
6327 makes no sense of talking about DSEG lenght.
6329 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6331 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6332 in certain cases, e.g. when ROM assignment, patch provided
6333 from Albert den Haan.
6335 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6478 * src/mcs51/peephole.def,
6479 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
6480 (allows non-interrupt and interrupt code to safely compete for a resource

6491 multiply defined with mismatching "at" address.
6493 2003-12-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6495 * src/ds390/main.c (PORT tininative_port): fixed bug #858416

6574 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6576 * src/SDCCast.c (decorateType): disabled a transformation I added in
6577 revision 1.188 (access to fields of a structure at an absolute address);
6578 it breaks with bitfields, extern declarations, and gcse analysis.
6579 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6580 could be assigned through a pointer, so don't complain.
6581 * src/SDCCast.c (astErrors),
6583 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7218 * src/SDCCsymt.c (sclsFromPtr),
7220 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
7221 support for standard C idiom of memory mapped variables; for
7222 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7223 to xdata int at 0x1234 tempvar = 1.
7224 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7225 provided by Akiya ISHIDA

7241 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7243 Fixed bug #621531 (const & volatile confusion in the type chain).
7244 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
7245 refer to the const or volatile state of the pointer itself.

7310 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
7311 pcoderegs.h, ralloc.c, ralloc.h
7312 * main.c: added top header and GPL license notice
7313 * pcode.c: fixed the if-conditional warning
7315 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
7317 * device/lib/_mullong.c: replaced int by short for gcc
7319 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7336 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7337 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7338 fetching of the pointer
7339 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7340 copied from genNearPointerSet()
7341 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7342 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7343 If they pop r0/r1 they must be called in the opposite order than aopOp().
7344 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7345 (resp. --stack-auto), prepared for --xstack

7356 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7358 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7359 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7360 type for bits was changed. It resulted in bit variables becoming
7361 global, which is not permitted in PIC 14 assembly output.
7363 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7365 * doc/sdccman.lyx: various additions and updates. Rearranged sections
7367 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7369 Z80 and MCS51 linkers complaint if a public symbol is defined

7376 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7378 A few small changes that speed up the peephole optimizer.
7382 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7384 Try to make the peephole optimizer smarter by maintaining
7385 an association between the assembly source code and the
7386 iCodes that originated them. Put this information to use
7387 with a new peephole rule condition "notVolatile" so that
7388 the rules can be aggressive yet still safe.
7393 * src/mcs51/peeph.def
7395 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7399 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7400 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7401 if the left or right operand symbols have the accuse flag set.
7403 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7405 Changed the type of the result of the ! (NOT) operator to char;
7406 previously it returned the same type as the source. This allows
7407 us to eliminate all the genFloatNot functions (all of its target
7408 implementations were very buggy) since !float can use the same
7411 * src/SDCCicode.c (ast2iCode): ! returns char
7412 * src/mcs51/gen.c (genNot, genNotFloat),
7413 * src/ds390/gen.c (genNot, genNotFloat),
7414 * src/z80/gen.c (genNot, genNotFloat),
7415 * src/pic/gen.c (genNot, genNotFloat),

7418 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7420 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7421 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7422 during interrupts. Ensure WSAVE is located at a shared bank address.
7423 2. Fixed page selection in some places
7424 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7425 the registers name strings.
7426 4. Fixed "signed / unsigned compare" compiler warnings.
7427 5. The PIC port manages its own allocation of the general purpose
7428 registers, but makes no attempt to reuse them. As a result when
7429 compiling it soon runs out of general purpose registers. Some
7430 additional code was added to the files pcode.c and device.c to walk
7431 through the function call tree and rename the registers so that they
7441 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7442 genPlus() & genMinus() when the result is the same as left or right
7444 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7448 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7450 Made bitfield a distinct type from bit so that bitfields
7451 convert as per ANSI C and bits retain their traditional
7452 boolean style behaviour. Implemented bitfield support in
7460 * src/ds390/gen.c: bit v bitfield split
7461 * src/z80/gen.c: New support for bitfields
7462 * support/regression/tests/bitfields.c: reenabled z80,
7465 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7467 Rules 246.x, 247.x relate to bitfields, the others speed up
7468 access to xdata mapped I/O devices.
7470 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7472 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7474 Cleaned up genPackBits and genUnpackBits and added two helper
7475 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7476 for literal assignments in genPackBits (thanks to Frieder for
7482 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7484 Fixed bug #748310 (pointer to function type mishandled when the
7485 function name is omitted). Also fixed a SIGSEGV when a function
7486 attribute (reentrant, etc) is used on a non-function or on a
7487 function but misplaced before the parameter list.
7489 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7491 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7492 * support/Util/SDCCerr.h,
7493 * support/Util/SDCCerr.c: Added func attr misuse error msg
7495 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
7497 Fixed bug #787649 by anonymous
7498 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

7514 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7516 Made the constant following the "interrupt" keyword optional. If
7517 omitted, the function will not automatically be given an entry
7518 in the interrupt vector table (similar to #pragma NOIV, but
7519 less syntacticly kludgy). The interrupt number is also now
7520 range checked. Also fixed a bug in the high order bit example

7534 * src/SDCCicode.c (operandOperation): rewritten some ops
7535 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7536 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7538 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7539 be re-activated by defining REDUCE_LITERALS)
7540 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7541 unsigned, but are signed by default
7542 * src/SDCCval.c (constVal): rearranged
7543 * src/SDCCval.c (valMod): preliminary fix
7544 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7586 constants are unsigned; added recognition of "u" flag for unsigned
7587 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
7588 * src/SDCCval.c (valDiv, valMod): fixed signdness
7589 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
7590 signedness of modulo, left and right shift

8050 added if/endif conditional macros to remove options help
8051 messages from optionsTable when a port is not configured, added
8052 support for the PIc16 port in the ports table, when executing
8053 the compiler with no port specified on command line, a default
8054 port is selected with the new macro DEFAULT_PORT which is
8055 defined in port.h, in setDefaultOptions() linkOptions is removed
8056 from initialization assignment, since now it is a set,
8057 parseCmdLine uses setParseWithComma for linkOptions, in
8058 linkEdit() linkOptions are accessed with new function indexSet()
8059 which returns the i'th item of a set variable. See SDCCset.c, in
8060 linkEdit() when calling buildCmdLine(), added linkOptions as
8061 last argument. Now users can pass arguments to gplink via the
8062 -Wl option, main() uses pic16glue() to glue up pic16 programs

8076 gpasm complaining and test the linkage with gplink, _linkCmd and
8077 _asmCmd changed to be more gplink and gpasm friendly
8078 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8079 produced an error when parsed, peep rule 12 is added to utilize
8080 movff, but it is commented out since the pCode does not support
8081 yet a command with 2 address arguments
8083 2003-05-18 <johan AT balder>
8085 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8112 2003-05-11 Borut Razem <borut.razem AT siol.net>
8114 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

9100 2003-01-09 Bernhard Held <bernhard AT bernhardheld.de>
9101 * src/mcs51/gen.c (genPlus): replaced "mov b,acc" by "mov b,a" Fiorenzo D. Ramaglia <fd.ramaglia AT tin.it>
9103 2003-01-07 <johan AT balder>
9105 * src/SDCCast.c (decorateType): fixed bug #600035
9107 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
9108 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings

9118 2003-01-06 <johan AT balder>
9120 * src/SDCCicode.c: fixed array add
9122 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
9123 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
9124 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9126 2003-01-04 <johan AT balder>
9128 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9130 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9131 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
9133 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9134 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
9135 * support/regression/tests/bug-524697.c: fit mem usage into 8032
9137 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
9138 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
9140 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
9141 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
9143 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9144 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9146 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9148 * in \sdcc\as\mcs51\ changed these files in order to create an
9149 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9150 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9151 following files to include the previous two files: aslink.dsp,
9152 Makefile.aslink, Makefile.bcc, and Makefile.in.
9154 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9155 .adb instead of .cdb
9157 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9159 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9160 value from option --iram-size.
9162 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9164 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9167 2002-09-18 <wiml AT hhhh.org>
9169 * SDCClrange.h: exposed setFromRange() and setToRange()
9170 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9171 packRegsForAccUse() (bug 542397)
9172 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9173 multiple times and emitting the fetch operations more than once
9174 added aopGetUsesAcc() function to allow binary operators to
9175 fetch their operands in the correct order; made genMinus() emit
9176 compact code for X = LITERAL - Y
9178 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9179 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9180 sprintf() in line 1267.
9182 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9183 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9186 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9187 Changes to aslink (All the changes are marked with 'JCF'):
9189 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9192 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9193 area BSEG. Also moves, if possible, the DATA area down into the internal
9194 ram so more space is available.
9196 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9199 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9200 not bytes. Function summary() which creates a memory usage summary
9201 file with extension .mem. Reports of overlaping stack and small stack
9202 size. If the space for the stack is less than 16 bytes aslink trows a
9205 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9206 the 8051. Option 'y' for memory summary output file.
9208 Changes to sdcc (All the changes are marked with 'JCF'):
9210 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9212 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9213 overlaying area for it (uses RegBankUsed[4]).
9215 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9216 bank zero as used by default. By default aslink locates the stack
9217 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9218 the creation of the .mem file. Delegates the allocation of data area
9219 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9220 the begining of the stack area to aslink.
9222 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9223 glue() in SDCCglue.c creates an area for it.
9225 2002-09-03 Borut Razem <borut.razem AT siol.net>
9226 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9227 sdcc/src/pic/glue.c:
9228 introduced atexit() handler for teporay files removal in case of
9229 errors, assertions, ...
9231 2002-08-29 Borut Razem <borut.razem AT siol.net>
9232 * sdcc/support/cpp2/auto-host_vc_in.h:
9233 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9234 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9235 Maybe there is a similar problem with BORLANDC? It should be checked!
9237 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9238 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9239 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9240 was not executed, and the compiler (cl) launched a warning:
9241 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9243 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9244 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9246 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9247 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9249 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9250 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9251 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9252 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9253 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9254 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9255 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9256 - added Release configuration in VS projects
9257 - review of compiler an linker options
9258 - VC .exe files are generated in bin_vc directory, not to interfere
9259 with binaries generated from other projects (cygwin, mingw, bcc ...)
9261 * sdcc/src/yacc.dsp: added
9263 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9264 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9265 and insert the version number definitions from .version
9267 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9269 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9270 added - genarate auto-host.h using auto-host_vc_in.h as template
9273 removed from CVS, generated automatically
9275 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9276 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9278 2002-08-11 Borut Razem <borut.razem AT siol.net>
9279 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9281 2002-08-10 Borut Razem <borut.razem AT siol.net>
9282 * src/SDCCmain.c (main):
9283 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9284 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9285 The consequence was that some temporary files were not removed.
9288 unification of code in functions tempfilename() and tempfile():
9289 function tempnam() is defined in Visual Studio 6.0 and .NET
9291 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9293 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9294 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9295 - removed compiler command line option /WX: Treats all warnings as errors
9296 - update a list of source files, included into the project
9298 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9299 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9300 changed project type to Generic Project so that can be correcly converted to VS.NET project
9302 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9304 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9306 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9308 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9309 added return 0 statements after assert() to make compiler happy
9311 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9312 added newline in the def file to keep MSC compiler satisfied
9314 * sdcc/src/z80/gen.c:
9315 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9316 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9317 - solved MSC error in function aopDump()
9319 * sdcc_vc.h: define PREFIX as "\\sdcc"
9321 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9322 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9324 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9325 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9326 - Rewrote the register banking algorithm.
9327 - Added pCode live-range analysis to registers (for now, only non-used and
9328 singly-used registers optimized away)
9330 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9332 * 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.
9334 2002-05-10 Scott Dattalo <scott AT dattalo.com>
9335 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
9337 2002-04-22 Michael Hope <michaelh AT vroom>

9357 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
9359 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
9361 2002-03-28 Johan Knol <johan AT balder>
9363 * src/SDCCval.c: fixed bug #532436
9365 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9367 Added "char *Processor" field to the port structure.
9370 Added -p option. Allows port dependent processor to be specified.
9373 Initialized the new field char *Processor field to NULL in all ports
9376 Compiler generated registers for interrupt context saving
9377 were not getting allocated.
9379 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9382 Fixed left shift. Will promote the left side of a left shift
9383 if a) left shifting more than size of operand or b) when assigned
9384 to something size > size of left side
9386 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9388 tons of changes. Register allocation has been
9389 rewritten. Added customization for the various PICs. Flow
9390 analysis is restructured. ...
9396 Added. device.c is a PIC port hack to accomodate variations
9399 2002-03-13 Michael Hope <michaelh AT vroom>
9401 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9403 2002-03-04 johanknol <johanknol AT manik>
9405 * /src/SDCCval.c: fixed
9407 const unsigned char arr[][2] = { { 0, 1 } };
9408 t18.c:1: error: Initializer element is not constant
9410 2002-03-04 bela <bela AT manik>
9412 * /device/include/mcs51reg.h:
9413 ds89c420 register definition update
9415 2002-03-03 <johan AT FRIJA>

9494 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9496 * sdcc/src/SDCCloop.c:
9497 Previous fix was not good. basic blocks that have "break" or "return" are
9498 not really partof a loop , but live ranges used in these blocks should
9499 be live thru the entire loop, so set partOfLoop but don't add them to
9502 2002-02-21 <johan AT FRIJA>
9504 * src/SDCCcse.c: fixed bug #514308
9506 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9509 Fixed BUG #519583. If a conditional block ended in a return/break
9510 statement inside a loop, it was not being considered part of the loop.
9512 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9514 2002-02-10 Karl Bongers <karl AT turbobit.com>
9517 Fixed up SDCDB debugger somewhat. Updated debugger/README
9518 with lots of comments and notes.
9520 * device/examples/test2.c:
9521 Fix bug, "red" variable not being initialized(compiler complained).
9523 * device/examples/Makefile, examples/test3.c:
9524 Add Makefile in device/examples folder, compiles test3.c
9525 for use as a multiple module SDCDB test case.
9527 * sim/ucsim/cmd.src/cmdset.cc:
9528 Took out debug printfs in ucsim "next" command.
9531 Karl and Johan start ucsim XA support. Most dissassembly working,
9532 about 75% emulation done(plenty of work remaining).
9534 * sim/ucsim/z80.src:
9535 Add Z80 support to ucsim, add test-ucz80 regression test,
9536 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
9537 Notice z80 compiler fails on examples/test3.c/crc code.
9539 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
9541 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
9542 Added support for --parms-in-bank1
9544 * src/ds390/peeph.def:
9545 added a few more peephole optimzations
9548 1) added __builtin_inp & __builtin_outp used to read in data of given length
9549 from a memory mapped port
9550 2) added __builtin_memcmp
9551 3) added __builtin_swapw swap bytes of a short
9553 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
9554 1) handle multiple send & receives from register bank1
9555 2) ralloc can now allocate DPTR1 to some liveRanges
9557 * src/SDCCsymt.c, src/SDCCsymt.h:
9558 changes to handle multiple sends & receives
9561 added some pointer arithmetic optimization
9564 added some pointer arithmetic optimizations but not stable yet so not
9565 called from anywhere (will get this working shortly)
9567 * src/SDCCopt.c: fixed for multiple sends & receives
9570 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
9571 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
9572 set preprocessor defines (depending on options)
9574 * src/SDCCicode.c, src/SDCCicode.h:
9575 changes made to handle multiple sends & receives
9578 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
