156 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
158 Enabled VPATH feature: changed nearly all Makefiles (149 files).
159 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
161 One basic decision: e.g. src/clean.mk includes further files. In order
162 to make this work there are two solutions:
163 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
164 run configure on them. This way they can use
165 'include $(srcdir)/port-clean.mk'
166 - always include clean.mk by the Makefile at the same level. To avoid
167 that `make clean` tries to include and build Makefile.dep the
168 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
169 implemented, because now even `make uninstall` doesn't create
170 Makefile.in. clean.mk could be eliminated by pasting it in
173 * debugger/mcs51/Makefile.in: build own objects from library sources
174 (SLIB, SDCC) in current directory
176 * configure, configure.in: renamed --disable-device-lib-build in
177 --disable-device-lib; added --enable-doc, the required tools are
178 searched by configure; added result message; the toolchain for the
179 belonging ports are now only built, if the port is enabled.
181 * support/regression/*: all output is written in directory gen, because
182 the fwk and ports directories don't livet in the build tree using vpath
184 * doc/sdccman.lyx: renamed --disable-device-lib-build to
185 --disable-device-lib, added --enable-doc, added section VPATH
187 * sim/ucsim/configure.in,
188 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
189 z80 are enabled by default
191 2006-04-24 Raphael Neider <rneider AT web.de>
193 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
194 to config word, "pic14_"-prefixed some extern functions
195 (pic14_emitConfigWord): emit __config directive(s) if assignment to
196 config word has been found
197 * src/pic/device.h: added prototypes
198 * src/pic/pcode.c: added "pic14_"-prefix where needed
199 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
201 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

204 (pic14createInterruptVect): moved generating __config directives away

215 fixes #1469504 and #1474602,
216 (pCodeRegOptimizeRegUsage): fixed typo in comment

472 submitted by the Debian SDCC maintainer Aurelien Jarno:
473 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
474 archive with gcc 4.1 on mips and wrote the patch"
476 2006-03-16 Raphael Neider <rneider AT web.de>
478 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
479 the left operand is shorter than the result (c* = lit-c* + int),
481 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
484 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
486 * src/.version: increased version number to 2.5.5
487 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
488 linking is done manually in pic16 port's _linkEdit,
489 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
490 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
491 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
492 allocate asmop as AOP_ACC,
493 (aopForRemat): added parameter 'bool result' in function declaration,
494 (pic16_aopGet): return AOP_ACC when accessing WREG,
495 (pic16_popGetTempReg): minor modification,
496 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
497 'pic16_allocWithIdx',
498 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
499 calling function in absolute addresses,
500 (genAssign): take into account AOP_ACC asmop,
501 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
502 * src/pic16/pcoderegs.c: some debug functions and lines added,
503 * src/pic16/ralloc.c (decodeRegType): added but commented out,
504 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
506 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
507 call to allocReg, not by manually allocating a new one,
508 (pic16_assignRegisters): now before going through the register
509 allocating functions mark all registers as free. This eliminates some
510 side effects resulting from peephole parser done earlier in the backbone
512 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

533 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
534 (aopForSym, aopOp): increment asmop.allocated if reused,
535 (freeAsmop): decrement asmop.allocated and check for zero instead of
537 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
538 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

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

2952 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2954 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2956 * device/lib/printf_large.c: removed inline assembly for portability and
2957 readability. Use printf_fast if speed or size are more important.
2958 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2959 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2961 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2963 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2964 prevent compiler warning
2966 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2968 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2969 moved to level 0 and declared as static. Also they are explicit
2970 placed in access bank. This was necessery because some times they
2971 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2972 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2973 optimizations. Currently only compare to unsigned char is implemented,
2974 * src/pic16/gen.c: added fReturnIdx array,
2975 * (struct resolvedIfx) is moved to gen.h and made public,
2976 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2977 * (aopForSym): added an optimization to directly store in stack of
2978 the operand of a SEND iCode,
2979 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2980 but as registers instead (AOP_REG) using the fReturnIdx array,
2981 * (pic16_freeAsmop): remove the freed register from the
2982 _G.sregsAlloc field,
2983 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2984 a compare of 'WREG',
2985 * (pic16_popGetTempRegCond): changed function prototype, now
2986 function takes also a bitVector argument v which holds the current
2987 set of registers that are allocated for stack access by aopForSym,
2988 registers allocated in aopForSym for accessing stack symbols are not
2989 any more part of the functions usedRegs field,
2990 * (genCall): some times aopOp is called for a stack variable to be
2991 send, aopForSym might perform the push, if this is true make sure
2992 that genCall doesn't push the variable twice by testing _G.resDirect,
2993 * (genFunction): changed testing for unspecified interrupt number
2994 from 256 to INTNO_UNSPEC,
2995 * modified selection scheme of frame pointer generation. Previously
2996 if function did use local registers a frame pointer was generated,
2997 now a frame pointer is generated only if function has arguments
2998 (that need PLUSW2 register access), or has stack arguments, or the
2999 compiler is not instructed to omit the frame pointer,
3000 * (genEndFunction): before restoring local registers that were saved
3001 in the function preamble, also restore the registers that *might*
3002 have been allocated for stack access,
3003 * (genRet): removed some old comments,
3004 * (genCmp, the active (RN's) version): added a call to the
3005 pic16_genCmp_special function to perform the compare with a more
3006 robust and optimized way,
3007 * (genInline): a feature has been added in inline code generation,
3008 which allows a wildcard variable substitution when writing inline
3009 assembly. Code is incomplete and experimental therefore undocumented,
3010 * (genCast): changed order of aopOp for result and right to allow
3011 aopForSym to directly load the result if possible,
3012 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3013 perform an optimized compare on some selected special occasions,
3014 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3015 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3016 generate an IVT any more,
3017 * src/pic16/main.c (pic16_optionsTable): added command line option
3019 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3020 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3022 * src/pic16/NOTES: Raphael Neider added in list of active developers
3023 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3024 jumptable_end to prevent bug #,
3025 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in

3680 Adding support for replacing ljmps with sjmps in jumptables
3681 generated for switch statements. For now you need to set the
3682 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3683 Now 4 algorithms for mcs51 jumptable generation are used:
3684 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3685 addresses loaded pc-relative for up to 112 cases and stack-pushing
3686 target addresses loaded with offset from dptr for up to 256 cases.

3716 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3718 * added libc directory. The current version of LibC contains string
3719 functions, ctype functions and macros and some functions of the
3720 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3721 be extensively tested in the future. Standard disclaimer here.
3722 Library is not automatically build yet. But one can build it by
3723 invoking 'make' inside the libc directory.

3734 * (pic16_storeForReturn): optimized return of 0,
3735 * (genCmp): experimental code for new genCmp which uses PIC18's
3736 special compare&skip instructions. Initial tests fail some times
3737 with variables grater than 1 byte in size, so new code is disabled,
3738 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3740 * (genCast): began a fix to optimize the casting of a bit to another
3741 bit, now assigning a bitfield to another bitfield will fail, sorry,

3750 and 1 for banking instruction,
3751 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3752 caused stop processing pCodes after a inline assembly block,
3753 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3755 registers when it shouldn't,
3756 * src/pic16/ralloc.c (allocReg): add preliminary support for
3757 supporting a limited set of temporary registers,
3759 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6767 loaded with the linker search paths (-L arguments) and the libraries
6768 to be linked with the current source (-l arguments). Changes
6769 currently will affect only the pic16 port.
6770 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6771 include path the port specific paths and port specific libraries,
6772 * gplink command now contains the $3 argument,
6773 * src/pic16/device.h,

6790 Documenting changes from previous commits.
6791 * configure.in (version 1.56),
6792 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6793 when generating output files to configure the pic16 library,
6794 but now I've commented it out, since gputils aren't installed in the
6795 SF compile farm, so library won't compile
6797 * device/lib/Makefile.in (version 1.56): initially I've added in
6798 target 'all' the prerequestive 'model-pic16' so it compiled the
6799 pic16 library, but now I've commented it out for the same reasons
6801 * added targets 'model-pic16' and 'objects-pic16' to compile the
6803 * added target 'port-specific-objects-pic16' to handle the
6804 generated libraries and copy them into the build/ directory
6805 * added target 'clean-intermediate-pic16' to clean intermediate
6806 files into pic16 directory
6807 * in target 'installdirs' added line to create directory pic16 in

6811 added lines to copy all header files to installation path,
6812 * in target 'installdirs' added line create directory for pic16
6813 headers in the installation path

7054 LEFT_OP (left shift)
7056 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7058 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7059 (default behaviour).
7061 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7063 A python script to validate compiler diagnostic messages. It can be
7064 used to verify that sdcc complains about bad c source code and
7065 gives a good location of the error.
7066 * support/valdiag/Makefile,
7067 * support/valdiag/valdiag.py,

7085 Bug reported from Jesus Calvino-Fraga
7087 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7089 * sdcc.spec: updated
7090 * device/include/Makefile.in: don't install CVS directories
7091 * device/lib/Makefile.in: added removal of CVS directories after install
7092 * doc/Makefile: fixed install, added local_icons
7093 * sim/ucsim/gui.src/Makefile.in: fixed an old typo

7098 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7100 PIC16 port related changes:
7101 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7102 added variable stackPos,
7104 * gen.c: genCall, assignResultValue: added support for
7105 pushing/retrieving function parameters to/from stack,
7106 genFunction,genEndFunction: setup stack frame for the
7108 genAddrOf: will be changed according to bug 863624
7110 * added files genutils.c and genutils.h which contain gen*
7111 debugged and optimised functions extracted from gen.c
7113 * glue.c: added variable 'externs' which holds extern symbols,
7114 pic16emitRegularMap: is modified to properly handle relocatable
7115 symbols under the new scheme,
7116 pic16createInterruptVect: is modified
7117 pic16printPublics: is modified to emit 'global' assembler directives,
7118 added pic16_printExterns to print extern symbols,
7119 pic16glue: initializes stack/frame pointer in the beginning of
7120 the assembly output. Temporary hack, will be corrected later,
7121 because gplink yet does not support stack and SDCC does not
7122 yet support a type of crt0.o object to create the final binary.
7124 * Removed many lines that contain 8051 legacy code.
7125 * The code is finally placed under a 'code' directive.
7126 * Added port specific options.
7128 * _process_pragma: simplified since now we do not need *special*
7129 include file to define SFR registers. But a separate header
7130 will be needed. This will be developed later.
7131 * _pic16_parseOptions: added, parses port specific options:
7132 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7133 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7134 --preplace-udata-with=
7136 * _pic16_setDefaultOptions: modified to initialize section names,
7137 but hack is temporarly out of order since it needs improvement.
7138 * _pic16_genAssemblerPreamble: configuration words are emitted by
7139 their address instead of their name. This part is incomplete and
7140 supports only the 18Fxx2 devices. Other devices will emit an error
7141 during assembly since they do not contain the same set of config
7143 * _pic16_genIVT: is modified,
7145 * pcode.c: added definitions for some hardware registers that are needed
7147 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7148 All PCI entries are updated. Now LFSR is supported.
7149 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7150 * added pic16_newpCodeOpLit2 to support instructions with
7151 two literal arguments
7152 * pic16_pCode2str: corrected code that emits assembler instructions
7153 with two literal operands and those that have an access bit modifier
7154 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7155 this fixes a bug which caused some labels to be lost, when an
7156 assembler directive was added, i.e. banksel,
7157 * pic16_FixRegisterBanking: improved logic that causes the insertion
7159 * InlineFunction: functions that are called once, are not any more
7160 inlined. This can be a port option in the future,
7162 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7164 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7165 hold the corresponding uninitialized symbols,
7166 * pic16_allocProcessorRegister: registers have explicit marked the
7168 * pic16_allocInternalRegister: registers are explicit marked as
7170 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7171 processing list, so bit registers were lost,
7174 * ralloc.h: added field 'accessBank' and original symbol operand
7175 in register definition,
7176 * removed the field isMapped from register definition,
7178 ** Several functions have been removed from various sources:
7179 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7180 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7181 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7182 pic16_assignRelocatableRegisters
7184 ** others have been introduced:
7185 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7186 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7188 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7190 * support/scripts/inc2h.pl: changed definition of BIT_AT
7191 to emit 'sbit at' instead of 'bit at'. This was a request.
7193 PIC16 port related preliminary changes:
7194 * gen.c: prefixed function popRegFromString with
7195 pic16_ and all references to it corrected
7196 * pcode.c: all pic16_pc_* hardware registers prefixed
7197 with underscore (_),
7198 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7199 * ralloc.c: newReg(): when register is REG_SFR then
7200 set address to rIdx,
7201 pic16_allocProcessorRegister(): marks register wasUsed=0
7202 pic16_writeUsedRegs(): added a call to assign processor
7203 registers via pic16_assignFixedRegisters
7205 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7207 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7208 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7209 variables in unused register banks. Also the SSEG is placed
7210 wherever there is enough space for it, and IDATA can be anywhere
7211 in internal RAM. For now compile using -Wl-Y[stack_size].
7212 The mem file is different for this option as well, since it
7213 makes no sense of talking about DSEG lenght.
7215 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7217 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7218 in certain cases, e.g. when ROM assignment, patch provided
7219 from Albert den Haan.
7221 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7460 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7462 * src/SDCCast.c (decorateType): disabled a transformation I added in
7463 revision 1.188 (access to fields of a structure at an absolute address);
7464 it breaks with bitfields, extern declarations, and gcse analysis.
7465 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7466 could be assigned through a pointer, so don't complain.
7467 * src/SDCCast.c (astErrors),
7469 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8106 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8107 support for standard C idiom of memory mapped variables; for
8108 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8109 to xdata int at 0x1234 tempvar = 1.
8110 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8111 provided by Akiya ISHIDA

8127 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8129 Fixed bug #621531 (const & volatile confusion in the type chain).
8130 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

8222 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8223 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8224 fetching of the pointer
8225 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8226 copied from genNearPointerSet()
8227 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8228 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8229 If they pop r0/r1 they must be called in the opposite order than aopOp().
8230 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8231 (resp. --stack-auto), prepared for --xstack

8242 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8244 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8245 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8246 type for bits was changed. It resulted in bit variables becoming
8247 global, which is not permitted in PIC 14 assembly output.
8249 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8251 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8264 A few small changes that speed up the peephole optimizer.
8268 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8270 Try to make the peephole optimizer smarter by maintaining
8271 an association between the assembly source code and the
8272 iCodes that originated them. Put this information to use
8273 with a new peephole rule condition "notVolatile" so that
8274 the rules can be aggressive yet still safe.
8279 * src/mcs51/peeph.def
8281 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8285 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8286 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8287 if the left or right operand symbols have the accuse flag set.
8289 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8291 Changed the type of the result of the ! (NOT) operator to char;
8292 previously it returned the same type as the source. This allows
8293 us to eliminate all the genFloatNot functions (all of its target
8294 implementations were very buggy) since !float can use the same
8297 * src/SDCCicode.c (ast2iCode): ! returns char

8306 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8307 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8308 during interrupts. Ensure WSAVE is located at a shared bank address.
8309 2. Fixed page selection in some places
8310 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8311 the registers name strings.
8312 4. Fixed "signed / unsigned compare" compiler warnings.
8313 5. The PIC port manages its own allocation of the general purpose
8314 registers, but makes no attempt to reuse them. As a result when
8315 compiling it soon runs out of general purpose registers. Some
8316 additional code was added to the files pcode.c and device.c to walk
8317 through the function call tree and rename the registers so that they
8327 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8328 genPlus() & genMinus() when the result is the same as left or right
8330 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8334 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8336 Made bitfield a distinct type from bit so that bitfields
8337 convert as per ANSI C and bits retain their traditional
8338 boolean style behaviour. Implemented bitfield support in
8346 * src/ds390/gen.c: bit v bitfield split
8347 * src/z80/gen.c: New support for bitfields
8348 * support/regression/tests/bitfields.c: reenabled z80,
8351 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8353 Rules 246.x, 247.x relate to bitfields, the others speed up
8354 access to xdata mapped I/O devices.
8356 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8358 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8360 Cleaned up genPackBits and genUnpackBits and added two helper
8361 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8362 for literal assignments in genPackBits (thanks to Frieder for
8368 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8370 Fixed bug #748310 (pointer to function type mishandled when the
8371 function name is omitted). Also fixed a SIGSEGV when a function
8372 attribute (reentrant, etc) is used on a non-function or on a
8373 function but misplaced before the parameter list.
8375 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8377 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8378 * support/Util/SDCCerr.h,
8379 * support/Util/SDCCerr.c: Added func attr misuse error msg

8400 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8402 Made the constant following the "interrupt" keyword optional. If
8403 omitted, the function will not automatically be given an entry
8404 in the interrupt vector table (similar to #pragma NOIV, but
8405 less syntacticly kludgy). The interrupt number is also now
8406 range checked. Also fixed a bug in the high order bit example

8420 * src/SDCCicode.c (operandOperation): rewritten some ops
8421 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8422 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8424 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8425 be re-activated by defining REDUCE_LITERALS)
8426 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8427 unsigned, but are signed by default
8428 * src/SDCCval.c (constVal): rearranged
8429 * src/SDCCval.c (valMod): preliminary fix
8430 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8472 constants are unsigned; added recognition of "u" flag for unsigned
8473 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8474 * src/SDCCval.c (valDiv, valMod): fixed signdness
8475 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8476 signedness of modulo, left and right shift

8936 added if/endif conditional macros to remove options help
8937 messages from optionsTable when a port is not configured, added
8938 support for the PIc16 port in the ports table, when executing
8939 the compiler with no port specified on command line, a default
8940 port is selected with the new macro DEFAULT_PORT which is
8941 defined in port.h, in setDefaultOptions() linkOptions is removed
8942 from initialization assignment, since now it is a set,
8943 parseCmdLine uses setParseWithComma for linkOptions, in
8944 linkEdit() linkOptions are accessed with new function indexSet()
8945 which returns the i'th item of a set variable. See SDCCset.c, in
8946 linkEdit() when calling buildCmdLine(), added linkOptions as
8947 last argument. Now users can pass arguments to gplink via the
8948 -Wl option, main() uses pic16glue() to glue up pic16 programs

8962 gpasm complaining and test the linkage with gplink, _linkCmd and
8963 _asmCmd changed to be more gplink and gpasm friendly
8964 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8965 produced an error when parsed, peep rule 12 is added to utilize
8966 movff, but it is commented out since the pCode does not support
8967 yet a command with 2 address arguments
8969 2003-05-18 <johan AT balder>
8971 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9993 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
9994 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
9995 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
9996 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings

10004 2003-01-06 <johan AT balder>
10006 * src/SDCCicode.c: fixed array add
10008 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10009 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10010 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10012 2003-01-04 <johan AT balder>
10014 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10016 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10017 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10019 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10020 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10021 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10023 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10024 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10026 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10027 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10029 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10030 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10032 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10034 * in \sdcc\as\mcs51\ changed these files in order to create an
10035 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10036 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10037 following files to include the previous two files: aslink.dsp,
10038 Makefile.aslink, Makefile.bcc, and Makefile.in.
10040 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10041 .adb instead of .cdb
10043 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10045 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10046 value from option --iram-size.
10048 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10050 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10053 2002-09-18 <wiml AT hhhh.org>
10055 * SDCClrange.h: exposed setFromRange() and setToRange()
10056 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10057 packRegsForAccUse() (bug 542397)
10058 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10059 multiple times and emitting the fetch operations more than once
10060 added aopGetUsesAcc() function to allow binary operators to
10061 fetch their operands in the correct order; made genMinus() emit
10062 compact code for X = LITERAL - Y
10064 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10065 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10066 sprintf() in line 1267.
10068 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10069 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10072 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10073 Changes to aslink (All the changes are marked with 'JCF'):
10075 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10078 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10079 area BSEG. Also moves, if possible, the DATA area down into the internal
10080 ram so more space is available.
10082 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10085 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10086 not bytes. Function summary() which creates a memory usage summary
10087 file with extension .mem. Reports of overlaping stack and small stack
10088 size. If the space for the stack is less than 16 bytes aslink trows a
10091 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10092 the 8051. Option 'y' for memory summary output file.
10094 Changes to sdcc (All the changes are marked with 'JCF'):
10096 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10098 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10099 overlaying area for it (uses RegBankUsed[4]).
10101 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10102 bank zero as used by default. By default aslink locates the stack
10103 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10104 the creation of the .mem file. Delegates the allocation of data area
10105 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10106 the begining of the stack area to aslink.
10108 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10109 glue() in SDCCglue.c creates an area for it.
10111 2002-09-03 Borut Razem <borut.razem AT siol.net>
10112 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10113 sdcc/src/pic/glue.c:
10114 introduced atexit() handler for teporay files removal in case of
10115 errors, assertions, ...
10117 2002-08-29 Borut Razem <borut.razem AT siol.net>
10118 * sdcc/support/cpp2/auto-host_vc_in.h:
10119 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10120 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10121 Maybe there is a similar problem with BORLANDC? It should be checked!
10123 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10124 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10125 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10126 was not executed, and the compiler (cl) launched a warning:
10127 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10129 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10130 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10132 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10133 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10135 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10136 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10137 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10138 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10139 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10140 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10141 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10142 - added Release configuration in VS projects
10143 - review of compiler an linker options
10144 - VC .exe files are generated in bin_vc directory, not to interfere
10145 with binaries generated from other projects (cygwin, mingw, bcc ...)
10147 * sdcc/src/yacc.dsp: added
10149 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10150 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10151 and insert the version number definitions from .version
10153 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10155 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10156 added - genarate auto-host.h using auto-host_vc_in.h as template
10159 removed from CVS, generated automatically
10161 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10162 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10164 2002-08-11 Borut Razem <borut.razem AT siol.net>
10165 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10167 2002-08-10 Borut Razem <borut.razem AT siol.net>
10168 * src/SDCCmain.c (main):
10169 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10170 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10171 The consequence was that some temporary files were not removed.
10174 unification of code in functions tempfilename() and tempfile():
10175 function tempnam() is defined in Visual Studio 6.0 and .NET
10177 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10179 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10180 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10181 - removed compiler command line option /WX: Treats all warnings as errors
10182 - update a list of source files, included into the project
10184 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10185 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10186 changed project type to Generic Project so that can be correcly converted to VS.NET project
10188 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10190 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10192 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10194 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10195 added return 0 statements after assert() to make compiler happy
10197 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10198 added newline in the def file to keep MSC compiler satisfied
10200 * sdcc/src/z80/gen.c:
10201 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10202 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10203 - solved MSC error in function aopDump()
10205 * sdcc_vc.h: define PREFIX as "\\sdcc"
10207 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10208 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10211 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10212 - Rewrote the register banking algorithm.
10213 - Added pCode live-range analysis to registers (for now, only non-used and
10214 singly-used registers optimized away)
10216 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10218 * 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.

10235 * device/lib/z80/printf.c (sprintf): Added.
10237 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
10239 * src/z80/peeph.def: Added transpose redundent load rule.
10241 * src/z80/main.c: Added force callee saves for jaune.
10243 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10245 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10247 2002-03-28 Johan Knol <johan AT balder>
10249 * src/SDCCval.c: fixed bug #532436
10251 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10253 Added "char *Processor" field to the port structure.
10256 Added -p option. Allows port dependent processor to be specified.
10259 Initialized the new field char *Processor field to NULL in all ports
10262 Compiler generated registers for interrupt context saving
10263 were not getting allocated.
10265 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10268 Fixed left shift. Will promote the left side of a left shift
10269 if a) left shifting more than size of operand or b) when assigned
10270 to something size > size of left side
10272 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10274 tons of changes. Register allocation has been
10275 rewritten. Added customization for the various PICs. Flow
10276 analysis is restructured. ...
10278 * src/pic/device.h:
10281 * src/pic/device.c:
10282 Added. device.c is a PIC port hack to accomodate variations
10285 2002-03-13 Michael Hope <michaelh AT vroom>
10287 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10289 2002-03-04 johanknol <johanknol AT manik>
10291 * /src/SDCCval.c: fixed
10293 const unsigned char arr[][2] = { { 0, 1 } };
10294 t18.c:1: error: Initializer element is not constant

10380 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10382 * sdcc/src/SDCCloop.c:
10383 Previous fix was not good. basic blocks that have "break" or "return" are
10384 not really partof a loop , but live ranges used in these blocks should
10385 be live thru the entire loop, so set partOfLoop but don't add them to
10388 2002-02-21 <johan AT FRIJA>
10390 * src/SDCCcse.c: fixed bug #514308
10392 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10395 Fixed BUG #519583. If a conditional block ended in a return/break
10396 statement inside a loop, it was not being considered part of the loop.
10398 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10400 2002-02-10 Karl Bongers <karl AT turbobit.com>

10404 with lots of comments and notes.
10406 * device/examples/test2.c:
10407 Fix bug, "red" variable not being initialized(compiler complained).
10409 * device/examples/Makefile, examples/test3.c:
10410 Add Makefile in device/examples folder, compiles test3.c
10411 for use as a multiple module SDCDB test case.
10413 * sim/ucsim/cmd.src/cmdset.cc:
10414 Took out debug printfs in ucsim "next" command.
10416 * sim/ucsim/xa.src:
10417 Karl and Johan start ucsim XA support. Most dissassembly working,
10418 about 75% emulation done(plenty of work remaining).
10420 * sim/ucsim/z80.src:
10421 Add Z80 support to ucsim, add test-ucz80 regression test,
10422 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10423 Notice z80 compiler fails on examples/test3.c/crc code.
10425 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
10427 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
10428 Added support for --parms-in-bank1
10430 * src/ds390/peeph.def:
10431 added a few more peephole optimzations
10433 * src/ds390/main.c:
10434 1) added __builtin_inp & __builtin_outp used to read in data of given length
