161 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
163 Enabled VPATH feature: changed nearly all Makefiles (149 files).
164 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
166 One basic decision: e.g. src/clean.mk includes further files. In order
167 to make this work there are two solutions:
168 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
169 run configure on them. This way they can use
170 'include $(srcdir)/port-clean.mk'
171 - always include clean.mk by the Makefile at the same level. To avoid
172 that `make clean` tries to include and build Makefile.dep the
173 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
174 implemented, because now even `make uninstall` doesn't create
175 Makefile.in. clean.mk could be eliminated by pasting it in
178 * debugger/mcs51/Makefile.in: build own objects from library sources
179 (SLIB, SDCC) in current directory
181 * configure, configure.in: renamed --disable-device-lib-build in
182 --disable-device-lib; added --enable-doc, the required tools are
183 searched by configure; added result message; the toolchain for the
184 belonging ports are now only built, if the port is enabled.
186 * support/regression/*: all output is written in directory gen, because
187 the fwk and ports directories don't livet in the build tree using vpath
189 * doc/sdccman.lyx: renamed --disable-device-lib-build to
190 --disable-device-lib, added --enable-doc, added section VPATH
192 * sim/ucsim/configure.in,
193 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
194 z80 are enabled by default
196 2006-04-24 Raphael Neider <rneider AT web.de>
198 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
199 to config word, "pic14_"-prefixed some extern functions
200 (pic14_emitConfigWord): emit __config directive(s) if assignment to
201 config word has been found
202 * src/pic/device.h: added prototypes
203 * src/pic/pcode.c: added "pic14_"-prefix where needed

206 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

479 archive with gcc 4.1 on mips and wrote the patch"
481 2006-03-16 Raphael Neider <rneider AT web.de>
483 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
484 the left operand is shorter than the result (c* = lit-c* + int),
486 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
489 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
491 * src/.version: increased version number to 2.5.5
492 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
493 linking is done manually in pic16 port's _linkEdit,
494 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
495 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
496 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
497 allocate asmop as AOP_ACC,
498 (aopForRemat): added parameter 'bool result' in function declaration,
499 (pic16_aopGet): return AOP_ACC when accessing WREG,

511 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
512 call to allocReg, not by manually allocating a new one,
513 (pic16_assignRegisters): now before going through the register
514 allocating functions mark all registers as free. This eliminates some
515 side effects resulting from peephole parser done earlier in the backbone

575 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
576 which dumps before the function entry point a data byte which represents
577 the number of the local variables used by the specified function, added
578 'xinst' for initial support for Extended Instruction Support,
579 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
580 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
581 port->fun_prefix anymore (may change later),
582 (genFunction, genEndFunction): do not store/restore local registers for
583 _main (this should take care the --main-return command line option in
585 (genOr): removed some legacy pic-port instructions,
586 * src/pic16/genarith.c (genAddLit): re-enabled old code because
587 performing operations with SFR's causes data to be written more than
588 once to each SFR. Perhaps SFRs should be handled in special cases...
589 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
591 * src/pic16/main.c (_process_pragma): stack bound checking did not take
592 into account for stack starting position,
593 (struct OPTIONS pic16_optionsTable): added command line argument
594 --extended or -y for Extended Instruction Support,
595 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
596 (deassignLRs): *** perhaps the most important change, old 'for' code
597 (commented out for reference), didn't account for some registers which
598 were left marked 'not free' after a pointer operation. The change
599 reduces register usage a lot in some cases

2957 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2959 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2961 * device/lib/printf_large.c: removed inline assembly for portability and
2962 readability. Use printf_fast if speed or size are more important.
2963 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2964 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2966 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2968 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2969 prevent compiler warning
2971 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2973 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2974 moved to level 0 and declared as static. Also they are explicit
2975 placed in access bank. This was necessery because some times they
2976 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2977 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2978 optimizations. Currently only compare to unsigned char is implemented,
2979 * src/pic16/gen.c: added fReturnIdx array,
2980 * (struct resolvedIfx) is moved to gen.h and made public,
2981 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2982 * (aopForSym): added an optimization to directly store in stack of
2983 the operand of a SEND iCode,
2984 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2985 but as registers instead (AOP_REG) using the fReturnIdx array,
2986 * (pic16_freeAsmop): remove the freed register from the
2987 _G.sregsAlloc field,
2988 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2989 a compare of 'WREG',
2990 * (pic16_popGetTempRegCond): changed function prototype, now
2991 function takes also a bitVector argument v which holds the current
2992 set of registers that are allocated for stack access by aopForSym,
2993 registers allocated in aopForSym for accessing stack symbols are not
2994 any more part of the functions usedRegs field,
2995 * (genCall): some times aopOp is called for a stack variable to be
2996 send, aopForSym might perform the push, if this is true make sure
2997 that genCall doesn't push the variable twice by testing _G.resDirect,
2998 * (genFunction): changed testing for unspecified interrupt number
2999 from 256 to INTNO_UNSPEC,
3000 * modified selection scheme of frame pointer generation. Previously
3001 if function did use local registers a frame pointer was generated,
3002 now a frame pointer is generated only if function has arguments
3003 (that need PLUSW2 register access), or has stack arguments, or the
3004 compiler is not instructed to omit the frame pointer,
3005 * (genEndFunction): before restoring local registers that were saved
3006 in the function preamble, also restore the registers that *might*
3007 have been allocated for stack access,
3008 * (genRet): removed some old comments,
3009 * (genCmp, the active (RN's) version): added a call to the
3010 pic16_genCmp_special function to perform the compare with a more
3011 robust and optimized way,
3012 * (genInline): a feature has been added in inline code generation,
3013 which allows a wildcard variable substitution when writing inline
3014 assembly. Code is incomplete and experimental therefore undocumented,
3015 * (genCast): changed order of aopOp for result and right to allow
3016 aopForSym to directly load the result if possible,
3017 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3018 perform an optimized compare on some selected special occasions,
3019 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3020 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3021 generate an IVT any more,
3022 * src/pic16/main.c (pic16_optionsTable): added command line option
3024 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3025 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3027 * src/pic16/NOTES: Raphael Neider added in list of active developers
3028 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and

3685 Adding support for replacing ljmps with sjmps in jumptables
3686 generated for switch statements. For now you need to set the
3687 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3688 Now 4 algorithms for mcs51 jumptable generation are used:
3689 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3721 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3723 * added libc directory. The current version of LibC contains string
3724 functions, ctype functions and macros and some functions of the
3725 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3726 be extensively tested in the future. Standard disclaimer here.
3727 Library is not automatically build yet. But one can build it by
3728 invoking 'make' inside the libc directory.

3739 * (pic16_storeForReturn): optimized return of 0,
3740 * (genCmp): experimental code for new genCmp which uses PIC18's
3741 special compare&skip instructions. Initial tests fail some times
3742 with variables grater than 1 byte in size, so new code is disabled,
3743 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3745 * (genCast): began a fix to optimize the casting of a bit to another
3746 bit, now assigning a bitfield to another bitfield will fail, sorry,

3755 and 1 for banking instruction,
3756 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3757 caused stop processing pCodes after a inline assembly block,
3758 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3760 registers when it shouldn't,
3761 * src/pic16/ralloc.c (allocReg): add preliminary support for
3762 supporting a limited set of temporary registers,
3764 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3770 (genFunction): optimize RECEIVE iCodes in reentrant functions
3772 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6772 loaded with the linker search paths (-L arguments) and the libraries
6773 to be linked with the current source (-l arguments). Changes
6774 currently will affect only the pic16 port.
6775 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6776 include path the port specific paths and port specific libraries,
6777 * gplink command now contains the $3 argument,
6778 * src/pic16/device.h,

6795 Documenting changes from previous commits.
6796 * configure.in (version 1.56),
6797 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6798 when generating output files to configure the pic16 library,
6799 but now I've commented it out, since gputils aren't installed in the
6800 SF compile farm, so library won't compile
6802 * device/lib/Makefile.in (version 1.56): initially I've added in
6803 target 'all' the prerequestive 'model-pic16' so it compiled the
6804 pic16 library, but now I've commented it out for the same reasons
6806 * added targets 'model-pic16' and 'objects-pic16' to compile the
6808 * added target 'port-specific-objects-pic16' to handle the
6809 generated libraries and copy them into the build/ directory
6810 * added target 'clean-intermediate-pic16' to clean intermediate
6811 files into pic16 directory
6812 * in target 'installdirs' added line to create directory pic16 in

6816 added lines to copy all header files to installation path,
6817 * in target 'installdirs' added line create directory for pic16
6818 headers in the installation path

7057 * src/SDCCast.c (decorateType),
7058 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7059 LEFT_OP (left shift)
7061 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7063 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7064 (default behaviour).
7066 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7068 A python script to validate compiler diagnostic messages. It can be
7069 used to verify that sdcc complains about bad c source code and
7070 gives a good location of the error.
7071 * support/valdiag/Makefile,
7072 * support/valdiag/valdiag.py,
7073 * support/valdiag/tests/*
7075 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7086 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7088 * src/common.h: added ifndef/define/endif macros
7089 around the header file.
7090 Bug reported from Jesus Calvino-Fraga
7092 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7094 * sdcc.spec: updated
7095 * device/include/Makefile.in: don't install CVS directories
7096 * device/lib/Makefile.in: added removal of CVS directories after install
7097 * doc/Makefile: fixed install, added local_icons
7098 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7099 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7100 * src/ds390/gen.c (genRightShift): fixed bug #870788
7101 * src/SDCCast.c (decorateType): fixed bug #870781
7103 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7105 PIC16 port related changes:
7106 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7107 added variable stackPos,
7109 * gen.c: genCall, assignResultValue: added support for
7110 pushing/retrieving function parameters to/from stack,
7111 genFunction,genEndFunction: setup stack frame for the
7113 genAddrOf: will be changed according to bug 863624
7115 * added files genutils.c and genutils.h which contain gen*
7116 debugged and optimised functions extracted from gen.c
7118 * glue.c: added variable 'externs' which holds extern symbols,
7119 pic16emitRegularMap: is modified to properly handle relocatable
7120 symbols under the new scheme,
7121 pic16createInterruptVect: is modified
7122 pic16printPublics: is modified to emit 'global' assembler directives,
7123 added pic16_printExterns to print extern symbols,
7124 pic16glue: initializes stack/frame pointer in the beginning of
7125 the assembly output. Temporary hack, will be corrected later,
7126 because gplink yet does not support stack and SDCC does not
7127 yet support a type of crt0.o object to create the final binary.
7129 * Removed many lines that contain 8051 legacy code.
7130 * The code is finally placed under a 'code' directive.
7131 * Added port specific options.
7133 * _process_pragma: simplified since now we do not need *special*
7134 include file to define SFR registers. But a separate header
7135 will be needed. This will be developed later.
7136 * _pic16_parseOptions: added, parses port specific options:
7137 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7138 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7139 --preplace-udata-with=
7141 * _pic16_setDefaultOptions: modified to initialize section names,
7142 but hack is temporarly out of order since it needs improvement.
7143 * _pic16_genAssemblerPreamble: configuration words are emitted by
7144 their address instead of their name. This part is incomplete and
7145 supports only the 18Fxx2 devices. Other devices will emit an error
7146 during assembly since they do not contain the same set of config
7148 * _pic16_genIVT: is modified,
7150 * pcode.c: added definitions for some hardware registers that are needed
7152 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7153 All PCI entries are updated. Now LFSR is supported.
7154 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7155 * added pic16_newpCodeOpLit2 to support instructions with
7156 two literal arguments
7157 * pic16_pCode2str: corrected code that emits assembler instructions
7158 with two literal operands and those that have an access bit modifier
7159 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7160 this fixes a bug which caused some labels to be lost, when an
7161 assembler directive was added, i.e. banksel,
7162 * pic16_FixRegisterBanking: improved logic that causes the insertion
7164 * InlineFunction: functions that are called once, are not any more
7165 inlined. This can be a port option in the future,
7167 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7169 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7170 hold the corresponding uninitialized symbols,
7171 * pic16_allocProcessorRegister: registers have explicit marked the
7173 * pic16_allocInternalRegister: registers are explicit marked as
7175 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7176 processing list, so bit registers were lost,
7179 * ralloc.h: added field 'accessBank' and original symbol operand
7180 in register definition,
7181 * removed the field isMapped from register definition,
7183 ** Several functions have been removed from various sources:
7184 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7185 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7186 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7187 pic16_assignRelocatableRegisters
7189 ** others have been introduced:
7190 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7191 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7193 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7195 * support/scripts/inc2h.pl: changed definition of BIT_AT
7196 to emit 'sbit at' instead of 'bit at'. This was a request.
7198 PIC16 port related preliminary changes:
7199 * gen.c: prefixed function popRegFromString with
7200 pic16_ and all references to it corrected
7201 * pcode.c: all pic16_pc_* hardware registers prefixed
7202 with underscore (_),
7203 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7204 * ralloc.c: newReg(): when register is REG_SFR then
7205 set address to rIdx,
7206 pic16_allocProcessorRegister(): marks register wasUsed=0
7207 pic16_writeUsedRegs(): added a call to assign processor
7208 registers via pic16_assignFixedRegisters
7210 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7212 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7213 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7214 variables in unused register banks. Also the SSEG is placed
7215 wherever there is enough space for it, and IDATA can be anywhere
7216 in internal RAM. For now compile using -Wl-Y[stack_size].
7217 The mem file is different for this option as well, since it
7218 makes no sense of talking about DSEG lenght.
7220 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7222 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7223 in certain cases, e.g. when ROM assignment, patch provided
7224 from Albert den Haan.
7226 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7465 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7467 * src/SDCCast.c (decorateType): disabled a transformation I added in
7468 revision 1.188 (access to fields of a structure at an absolute address);
7469 it breaks with bitfields, extern declarations, and gcse analysis.
7470 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7471 could be assigned through a pointer, so don't complain.
7472 * src/SDCCast.c (astErrors),
7474 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8111 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8112 support for standard C idiom of memory mapped variables; for
8113 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8114 to xdata int at 0x1234 tempvar = 1.
8115 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8116 provided by Akiya ISHIDA

8132 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8134 Fixed bug #621531 (const & volatile confusion in the type chain).
8135 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

8227 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8228 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8229 fetching of the pointer
8230 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8231 copied from genNearPointerSet()
8232 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8233 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8234 If they pop r0/r1 they must be called in the opposite order than aopOp().
8235 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8236 (resp. --stack-auto), prepared for --xstack

8247 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8249 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8250 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8251 type for bits was changed. It resulted in bit variables becoming
8252 global, which is not permitted in PIC 14 assembly output.
8254 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8256 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8269 A few small changes that speed up the peephole optimizer.
8273 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8275 Try to make the peephole optimizer smarter by maintaining
8276 an association between the assembly source code and the
8277 iCodes that originated them. Put this information to use
8278 with a new peephole rule condition "notVolatile" so that
8279 the rules can be aggressive yet still safe.
8284 * src/mcs51/peeph.def
8286 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8290 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8291 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8292 if the left or right operand symbols have the accuse flag set.
8294 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8296 Changed the type of the result of the ! (NOT) operator to char;
8297 previously it returned the same type as the source. This allows
8298 us to eliminate all the genFloatNot functions (all of its target
8299 implementations were very buggy) since !float can use the same
8302 * src/SDCCicode.c (ast2iCode): ! returns char

8311 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8312 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8313 during interrupts. Ensure WSAVE is located at a shared bank address.
8314 2. Fixed page selection in some places
8315 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8316 the registers name strings.
8317 4. Fixed "signed / unsigned compare" compiler warnings.
8318 5. The PIC port manages its own allocation of the general purpose
8319 registers, but makes no attempt to reuse them. As a result when
8320 compiling it soon runs out of general purpose registers. Some
8321 additional code was added to the files pcode.c and device.c to walk
8322 through the function call tree and rename the registers so that they
8332 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8333 genPlus() & genMinus() when the result is the same as left or right
8335 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8339 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8341 Made bitfield a distinct type from bit so that bitfields
8342 convert as per ANSI C and bits retain their traditional
8343 boolean style behaviour. Implemented bitfield support in
8351 * src/ds390/gen.c: bit v bitfield split
8352 * src/z80/gen.c: New support for bitfields
8353 * support/regression/tests/bitfields.c: reenabled z80,
8356 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8358 Rules 246.x, 247.x relate to bitfields, the others speed up
8359 access to xdata mapped I/O devices.
8361 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8363 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8365 Cleaned up genPackBits and genUnpackBits and added two helper
8366 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8367 for literal assignments in genPackBits (thanks to Frieder for
8373 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8375 Fixed bug #748310 (pointer to function type mishandled when the
8376 function name is omitted). Also fixed a SIGSEGV when a function
8377 attribute (reentrant, etc) is used on a non-function or on a
8378 function but misplaced before the parameter list.
8380 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8382 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8383 * support/Util/SDCCerr.h,
8384 * support/Util/SDCCerr.c: Added func attr misuse error msg
8386 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8388 Fixed bug #787649 by anonymous
8389 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

8405 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8407 Made the constant following the "interrupt" keyword optional. If
8408 omitted, the function will not automatically be given an entry
8409 in the interrupt vector table (similar to #pragma NOIV, but
8410 less syntacticly kludgy). The interrupt number is also now
8411 range checked. Also fixed a bug in the high order bit example

8425 * src/SDCCicode.c (operandOperation): rewritten some ops
8426 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8427 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8429 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8430 be re-activated by defining REDUCE_LITERALS)
8431 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8432 unsigned, but are signed by default
8433 * src/SDCCval.c (constVal): rearranged
8434 * src/SDCCval.c (valMod): preliminary fix
8435 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8477 constants are unsigned; added recognition of "u" flag for unsigned
8478 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8479 * src/SDCCval.c (valDiv, valMod): fixed signdness
8480 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8481 signedness of modulo, left and right shift

8524 * support\librarian\configure.in
8525 * support\librarian\config_in.h
8526 * support\librarian\Makefile.in

8532 Messed up 'configure', so revert to previous version:
8536 2003-07-31 Bernhard Held <bernhard AT bernhardheld.de>
8538 * src/SDCCicode.c (operandOperation): 3. fix, this time for Alpha; ULONG has 64 bits
8539 there, while the mantissa of a double is "only" 53 bits wide.
8541 2003-07-31 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

8942 messages from optionsTable when a port is not configured, added
8943 support for the PIc16 port in the ports table, when executing
8944 the compiler with no port specified on command line, a default
8945 port is selected with the new macro DEFAULT_PORT which is
8946 defined in port.h, in setDefaultOptions() linkOptions is removed
8947 from initialization assignment, since now it is a set,
8948 parseCmdLine uses setParseWithComma for linkOptions, in
8949 linkEdit() linkOptions are accessed with new function indexSet()
8950 which returns the i'th item of a set variable. See SDCCset.c, in
8951 linkEdit() when calling buildCmdLine(), added linkOptions as
8952 last argument. Now users can pass arguments to gplink via the
8953 -Wl option, main() uses pic16glue() to glue up pic16 programs

8967 gpasm complaining and test the linkage with gplink, _linkCmd and
8968 _asmCmd changed to be more gplink and gpasm friendly
8969 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8970 produced an error when parsed, peep rule 12 is added to utilize
8971 movff, but it is commented out since the pCode does not support
8972 yet a command with 2 address arguments
8974 2003-05-18 <johan AT balder>
8976 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9996 * src/SDCCast.c (decorateType): fixed bug #600035
9998 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
9999 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
10000 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
10001 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
10002 * src/pic/pcode.c: outcommented unused variable to remove warnings

10009 2003-01-06 <johan AT balder>
10011 * src/SDCCicode.c: fixed array add
10013 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10014 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10015 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10017 2003-01-04 <johan AT balder>
10019 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10021 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10022 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10024 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10025 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10026 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10028 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10029 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10031 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10032 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10034 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10035 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10037 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10039 * in \sdcc\as\mcs51\ changed these files in order to create an
10040 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10041 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10042 following files to include the previous two files: aslink.dsp,
10043 Makefile.aslink, Makefile.bcc, and Makefile.in.
10045 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10046 .adb instead of .cdb
10048 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10050 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10051 value from option --iram-size.
10053 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10055 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10058 2002-09-18 <wiml AT hhhh.org>
10060 * SDCClrange.h: exposed setFromRange() and setToRange()
10061 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10062 packRegsForAccUse() (bug 542397)
10063 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10064 multiple times and emitting the fetch operations more than once
10065 added aopGetUsesAcc() function to allow binary operators to
10066 fetch their operands in the correct order; made genMinus() emit
10067 compact code for X = LITERAL - Y
10069 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10070 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10071 sprintf() in line 1267.
10073 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10074 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10077 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10078 Changes to aslink (All the changes are marked with 'JCF'):
10080 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10083 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10084 area BSEG. Also moves, if possible, the DATA area down into the internal
10085 ram so more space is available.
10087 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10090 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10091 not bytes. Function summary() which creates a memory usage summary
10092 file with extension .mem. Reports of overlaping stack and small stack
10093 size. If the space for the stack is less than 16 bytes aslink trows a
10096 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10097 the 8051. Option 'y' for memory summary output file.
10099 Changes to sdcc (All the changes are marked with 'JCF'):
10101 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10103 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10104 overlaying area for it (uses RegBankUsed[4]).
10106 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10107 bank zero as used by default. By default aslink locates the stack
10108 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10109 the creation of the .mem file. Delegates the allocation of data area
10110 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10111 the begining of the stack area to aslink.
10113 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10114 glue() in SDCCglue.c creates an area for it.
10116 2002-09-03 Borut Razem <borut.razem AT siol.net>
10117 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10118 sdcc/src/pic/glue.c:
10119 introduced atexit() handler for teporay files removal in case of
10120 errors, assertions, ...
10122 2002-08-29 Borut Razem <borut.razem AT siol.net>
10123 * sdcc/support/cpp2/auto-host_vc_in.h:
10124 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10125 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10126 Maybe there is a similar problem with BORLANDC? It should be checked!
10128 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10129 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10130 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10131 was not executed, and the compiler (cl) launched a warning:
10132 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10134 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10135 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10137 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10138 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10140 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10141 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10142 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10143 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10144 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10145 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10146 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10147 - added Release configuration in VS projects
10148 - review of compiler an linker options
10149 - VC .exe files are generated in bin_vc directory, not to interfere
10150 with binaries generated from other projects (cygwin, mingw, bcc ...)
10152 * sdcc/src/yacc.dsp: added
10154 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10155 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10156 and insert the version number definitions from .version
10158 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10160 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10161 added - genarate auto-host.h using auto-host_vc_in.h as template
10164 removed from CVS, generated automatically
10166 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10167 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10169 2002-08-11 Borut Razem <borut.razem AT siol.net>
10170 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10172 2002-08-10 Borut Razem <borut.razem AT siol.net>
10173 * src/SDCCmain.c (main):
10174 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10175 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10176 The consequence was that some temporary files were not removed.
10179 unification of code in functions tempfilename() and tempfile():
10180 function tempnam() is defined in Visual Studio 6.0 and .NET
10182 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10184 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10185 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10186 - removed compiler command line option /WX: Treats all warnings as errors
10187 - update a list of source files, included into the project
10189 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10190 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10191 changed project type to Generic Project so that can be correcly converted to VS.NET project
10193 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10195 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10197 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10199 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10200 added return 0 statements after assert() to make compiler happy
10202 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10203 added newline in the def file to keep MSC compiler satisfied
10205 * sdcc/src/z80/gen.c:
10206 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10207 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10208 - solved MSC error in function aopDump()
10210 * sdcc_vc.h: define PREFIX as "\\sdcc"
10212 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10213 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10216 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10217 - Rewrote the register banking algorithm.
10218 - Added pCode live-range analysis to registers (for now, only non-used and
10219 singly-used registers optimized away)
10221 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10223 * 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.

10240 * device/lib/z80/printf.c (sprintf): Added.
10242 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
10244 * src/z80/peeph.def: Added transpose redundent load rule.
10246 * src/z80/main.c: Added force callee saves for jaune.
10248 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10250 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10252 2002-03-28 Johan Knol <johan AT balder>
10254 * src/SDCCval.c: fixed bug #532436
10256 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10258 Added "char *Processor" field to the port structure.
10261 Added -p option. Allows port dependent processor to be specified.
10264 Initialized the new field char *Processor field to NULL in all ports
10267 Compiler generated registers for interrupt context saving
10268 were not getting allocated.
10270 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10273 Fixed left shift. Will promote the left side of a left shift
10274 if a) left shifting more than size of operand or b) when assigned
10275 to something size > size of left side
10277 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10279 tons of changes. Register allocation has been
10280 rewritten. Added customization for the various PICs. Flow
10281 analysis is restructured. ...
10283 * src/pic/device.h:
10286 * src/pic/device.c:
10287 Added. device.c is a PIC port hack to accomodate variations
10290 2002-03-13 Michael Hope <michaelh AT vroom>
10292 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10294 2002-03-04 johanknol <johanknol AT manik>
10296 * /src/SDCCval.c: fixed
10298 const unsigned char arr[][2] = { { 0, 1 } };
10299 t18.c:1: error: Initializer element is not constant

10385 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10387 * sdcc/src/SDCCloop.c:
10388 Previous fix was not good. basic blocks that have "break" or "return" are
10389 not really partof a loop , but live ranges used in these blocks should
10390 be live thru the entire loop, so set partOfLoop but don't add them to
10393 2002-02-21 <johan AT FRIJA>
10395 * src/SDCCcse.c: fixed bug #514308
10397 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10400 Fixed BUG #519583. If a conditional block ended in a return/break
10401 statement inside a loop, it was not being considered part of the loop.
10403 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10405 2002-02-10 Karl Bongers <karl AT turbobit.com>

10414 * device/examples/Makefile, examples/test3.c:
10415 Add Makefile in device/examples folder, compiles test3.c
10416 for use as a multiple module SDCDB test case.
10418 * sim/ucsim/cmd.src/cmdset.cc:
10419 Took out debug printfs in ucsim "next" command.
10421 * sim/ucsim/xa.src:
10422 Karl and Johan start ucsim XA support. Most dissassembly working,
10423 about 75% emulation done(plenty of work remaining).
10425 * sim/ucsim/z80.src:
10426 Add Z80 support to ucsim, add test-ucz80 regression test,
10427 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10428 Notice z80 compiler fails on examples/test3.c/crc code.
10430 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
10432 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
10433 Added support for --parms-in-bank1
10435 * src/ds390/peeph.def:
10436 added a few more peephole optimzations
10438 * src/ds390/main.c:
10439 1) added __builtin_inp & __builtin_outp used to read in data of given length
