174 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
176 Enabled VPATH feature: changed nearly all Makefiles (149 files).
177 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
179 One basic decision: e.g. src/clean.mk includes further files. In order
180 to make this work there are two solutions:
181 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
182 run configure on them. This way they can use
183 'include $(srcdir)/port-clean.mk'
184 - always include clean.mk by the Makefile at the same level. To avoid
185 that `make clean` tries to include and build Makefile.dep the
186 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
187 implemented, because now even `make uninstall` doesn't create
188 Makefile.in. clean.mk could be eliminated by pasting it in
191 * debugger/mcs51/Makefile.in: build own objects from library sources
192 (SLIB, SDCC) in current directory
194 * configure, configure.in: renamed --disable-device-lib-build in
195 --disable-device-lib; added --enable-doc, the required tools are
196 searched by configure; added result message; the toolchain for the
197 belonging ports are now only built, if the port is enabled.
199 * support/regression/*: all output is written in directory gen, because
200 the fwk and ports directories don't livet in the build tree using vpath
202 * doc/sdccman.lyx: renamed --disable-device-lib-build to
203 --disable-device-lib, added --enable-doc, added section VPATH
205 * sim/ucsim/configure.in,
206 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
207 z80 are enabled by default
209 2006-04-24 Raphael Neider <rneider AT web.de>
211 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
212 to config word, "pic14_"-prefixed some extern functions
213 (pic14_emitConfigWord): emit __config directive(s) if assignment to
214 config word has been found
215 * src/pic/device.h: added prototypes
216 * src/pic/pcode.c: added "pic14_"-prefix where needed

480 implemented patch 1120823 Thanks to Willy De la Court (normal
481 interrupts need an interrupt number now if they are made critical),
482 and enabled nesting of critical functions though not for gbz80
483 (genCritical, genEndCritical): added functions
484 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
485 * src/z80/mappings.i: added "ei" to all mappings
487 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
489 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
490 submitted by the Debian SDCC maintainer Aurelien Jarno:
491 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
492 archive with gcc 4.1 on mips and wrote the patch"
494 2006-03-16 Raphael Neider <rneider AT web.de>
496 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
497 the left operand is shorter than the result (c* = lit-c* + int),
499 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
502 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
504 * src/.version: increased version number to 2.5.5
505 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
506 linking is done manually in pic16 port's _linkEdit,
507 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
508 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
509 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
510 allocate asmop as AOP_ACC,
511 (aopForRemat): added parameter 'bool result' in function declaration,
512 (pic16_aopGet): return AOP_ACC when accessing WREG,
513 (pic16_popGetTempReg): minor modification,
514 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
515 'pic16_allocWithIdx',
516 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
517 calling function in absolute addresses,
518 (genAssign): take into account AOP_ACC asmop,
519 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
520 * src/pic16/pcoderegs.c: some debug functions and lines added,
521 * src/pic16/ralloc.c (decodeRegType): added but commented out,
522 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
524 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
525 call to allocReg, not by manually allocating a new one,
526 (pic16_assignRegisters): now before going through the register
527 allocating functions mark all registers as free. This eliminates some
528 side effects resulting from peephole parser done earlier in the backbone
530 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
532 * src/SDCCicode.c (geniCodeLogic),
533 * src/SDCCast.c (decorateType): applied patch by Bernhard for rfe 1422617

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

580 2006-03-06 Borut Razem <borut.razem AT siol.net>
582 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
583 made the linker quiet
585 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
587 * src/pic16/gen.c (genPcall): fixed bug #1443644
588 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
589 which dumps before the function entry point a data byte which represents
590 the number of the local variables used by the specified function, added
591 'xinst' for initial support for Extended Instruction Support,
592 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
593 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
594 port->fun_prefix anymore (may change later),
595 (genFunction, genEndFunction): do not store/restore local registers for
596 _main (this should take care the --main-return command line option in
598 (genOr): removed some legacy pic-port instructions,
599 * src/pic16/genarith.c (genAddLit): re-enabled old code because
600 performing operations with SFR's causes data to be written more than
601 once to each SFR. Perhaps SFRs should be handled in special cases...
602 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
604 * src/pic16/main.c (_process_pragma): stack bound checking did not take
605 into account for stack starting position,
606 (struct OPTIONS pic16_optionsTable): added command line argument
607 --extended or -y for Extended Instruction Support,
608 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
609 (deassignLRs): *** perhaps the most important change, old 'for' code
610 (commented out for reference), didn't account for some registers which
611 were left marked 'not free' after a pointer operation. The change
612 reduces register usage a lot in some cases

2970 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2972 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2974 * device/lib/printf_large.c: removed inline assembly for portability and
2975 readability. Use printf_fast if speed or size are more important.
2976 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2977 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2979 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2981 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2982 prevent compiler warning
2984 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2986 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2987 moved to level 0 and declared as static. Also they are explicit
2988 placed in access bank. This was necessery because some times they
2989 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2990 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2991 optimizations. Currently only compare to unsigned char is implemented,
2992 * src/pic16/gen.c: added fReturnIdx array,
2993 * (struct resolvedIfx) is moved to gen.h and made public,
2994 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2995 * (aopForSym): added an optimization to directly store in stack of
2996 the operand of a SEND iCode,
2997 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2998 but as registers instead (AOP_REG) using the fReturnIdx array,
2999 * (pic16_freeAsmop): remove the freed register from the
3000 _G.sregsAlloc field,
3001 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3002 a compare of 'WREG',
3003 * (pic16_popGetTempRegCond): changed function prototype, now
3004 function takes also a bitVector argument v which holds the current
3005 set of registers that are allocated for stack access by aopForSym,
3006 registers allocated in aopForSym for accessing stack symbols are not
3007 any more part of the functions usedRegs field,
3008 * (genCall): some times aopOp is called for a stack variable to be
3009 send, aopForSym might perform the push, if this is true make sure
3010 that genCall doesn't push the variable twice by testing _G.resDirect,
3011 * (genFunction): changed testing for unspecified interrupt number
3012 from 256 to INTNO_UNSPEC,
3013 * modified selection scheme of frame pointer generation. Previously
3014 if function did use local registers a frame pointer was generated,
3015 now a frame pointer is generated only if function has arguments
3016 (that need PLUSW2 register access), or has stack arguments, or the
3017 compiler is not instructed to omit the frame pointer,
3018 * (genEndFunction): before restoring local registers that were saved
3019 in the function preamble, also restore the registers that *might*
3020 have been allocated for stack access,
3021 * (genRet): removed some old comments,
3022 * (genCmp, the active (RN's) version): added a call to the
3023 pic16_genCmp_special function to perform the compare with a more
3024 robust and optimized way,
3025 * (genInline): a feature has been added in inline code generation,
3026 which allows a wildcard variable substitution when writing inline
3027 assembly. Code is incomplete and experimental therefore undocumented,
3028 * (genCast): changed order of aopOp for result and right to allow
3029 aopForSym to directly load the result if possible,
3030 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3031 perform an optimized compare on some selected special occasions,
3032 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,

3699 generated for switch statements. For now you need to set the
3700 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3701 Now 4 algorithms for mcs51 jumptable generation are used:
3702 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3736 * added libc directory. The current version of LibC contains string
3737 functions, ctype functions and macros and some functions of the
3738 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3739 be extensively tested in the future. Standard disclaimer here.
3740 Library is not automatically build yet. But one can build it by
3741 invoking 'make' inside the libc directory.

3752 * (pic16_storeForReturn): optimized return of 0,
3753 * (genCmp): experimental code for new genCmp which uses PIC18's
3754 special compare&skip instructions. Initial tests fail some times
3755 with variables grater than 1 byte in size, so new code is disabled,
3756 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3758 * (genCast): began a fix to optimize the casting of a bit to another
3759 bit, now assigning a bitfield to another bitfield will fail, sorry,

3768 and 1 for banking instruction,
3769 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3770 caused stop processing pCodes after a inline assembly block,
3771 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3773 registers when it shouldn't,
3774 * src/pic16/ralloc.c (allocReg): add preliminary support for
3775 supporting a limited set of temporary registers,

6785 loaded with the linker search paths (-L arguments) and the libraries
6786 to be linked with the current source (-l arguments). Changes
6787 currently will affect only the pic16 port.
6788 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6789 include path the port specific paths and port specific libraries,
6790 * gplink command now contains the $3 argument,
6791 * src/pic16/device.h,
6792 * src/pic16/device.c,: structure PIC_device is made public and
6793 renamed to PIC16_device, the same for variable Pics which is renamed

6808 Documenting changes from previous commits.
6809 * configure.in (version 1.56),
6810 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6811 when generating output files to configure the pic16 library,
6812 but now I've commented it out, since gputils aren't installed in the
6813 SF compile farm, so library won't compile
6815 * device/lib/Makefile.in (version 1.56): initially I've added in
6816 target 'all' the prerequestive 'model-pic16' so it compiled the
6817 pic16 library, but now I've commented it out for the same reasons
6819 * added targets 'model-pic16' and 'objects-pic16' to compile the
6821 * added target 'port-specific-objects-pic16' to handle the
6822 generated libraries and copy them into the build/ directory
6823 * added target 'clean-intermediate-pic16' to clean intermediate
6824 files into pic16 directory
6825 * in target 'installdirs' added line to create directory pic16 in

6829 added lines to copy all header files to installation path,
6830 * in target 'installdirs' added line create directory for pic16
6831 headers in the installation path

7036 arguments via -W option
7037 * src/pic16/main.c: added $l in _asmCmd, changed extension for
7038 object file from '.rel' to '.o' in port->linker structure,
7039 changed size of fptr from 2 to 3 in port structure

7070 * src/SDCCast.c (decorateType),
7071 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7072 LEFT_OP (left shift)
7074 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7076 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7077 (default behaviour).
7079 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7081 A python script to validate compiler diagnostic messages. It can be
7082 used to verify that sdcc complains about bad c source code and
7083 gives a good location of the error.
7084 * support/valdiag/Makefile,
7085 * support/valdiag/valdiag.py,
7086 * support/valdiag/tests/*
7088 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7099 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7101 * src/common.h: added ifndef/define/endif macros
7102 around the header file.
7103 Bug reported from Jesus Calvino-Fraga
7105 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7107 * sdcc.spec: updated
7108 * device/include/Makefile.in: don't install CVS directories
7109 * device/lib/Makefile.in: added removal of CVS directories after install
7110 * doc/Makefile: fixed install, added local_icons
7111 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7112 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7113 * src/ds390/gen.c (genRightShift): fixed bug #870788

7116 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7118 PIC16 port related changes:
7119 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7120 added variable stackPos,
7122 * gen.c: genCall, assignResultValue: added support for
7123 pushing/retrieving function parameters to/from stack,
7124 genFunction,genEndFunction: setup stack frame for the
7126 genAddrOf: will be changed according to bug 863624
7128 * added files genutils.c and genutils.h which contain gen*
7129 debugged and optimised functions extracted from gen.c
7131 * glue.c: added variable 'externs' which holds extern symbols,
7132 pic16emitRegularMap: is modified to properly handle relocatable
7133 symbols under the new scheme,
7134 pic16createInterruptVect: is modified
7135 pic16printPublics: is modified to emit 'global' assembler directives,
7136 added pic16_printExterns to print extern symbols,
7137 pic16glue: initializes stack/frame pointer in the beginning of
7138 the assembly output. Temporary hack, will be corrected later,
7139 because gplink yet does not support stack and SDCC does not
7140 yet support a type of crt0.o object to create the final binary.
7142 * Removed many lines that contain 8051 legacy code.
7143 * The code is finally placed under a 'code' directive.
7144 * Added port specific options.
7146 * _process_pragma: simplified since now we do not need *special*
7147 include file to define SFR registers. But a separate header
7148 will be needed. This will be developed later.
7149 * _pic16_parseOptions: added, parses port specific options:
7150 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7151 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7152 --preplace-udata-with=
7154 * _pic16_setDefaultOptions: modified to initialize section names,
7155 but hack is temporarly out of order since it needs improvement.
7156 * _pic16_genAssemblerPreamble: configuration words are emitted by
7157 their address instead of their name. This part is incomplete and
7158 supports only the 18Fxx2 devices. Other devices will emit an error
7159 during assembly since they do not contain the same set of config
7161 * _pic16_genIVT: is modified,
7163 * pcode.c: added definitions for some hardware registers that are needed
7165 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7166 All PCI entries are updated. Now LFSR is supported.
7167 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7168 * added pic16_newpCodeOpLit2 to support instructions with
7169 two literal arguments
7170 * pic16_pCode2str: corrected code that emits assembler instructions
7171 with two literal operands and those that have an access bit modifier
7172 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7173 this fixes a bug which caused some labels to be lost, when an
7174 assembler directive was added, i.e. banksel,
7175 * pic16_FixRegisterBanking: improved logic that causes the insertion
7177 * InlineFunction: functions that are called once, are not any more
7178 inlined. This can be a port option in the future,
7180 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7182 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7183 hold the corresponding uninitialized symbols,
7184 * pic16_allocProcessorRegister: registers have explicit marked the
7186 * pic16_allocInternalRegister: registers are explicit marked as
7188 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7189 processing list, so bit registers were lost,
7192 * ralloc.h: added field 'accessBank' and original symbol operand
7193 in register definition,
7194 * removed the field isMapped from register definition,
7196 ** Several functions have been removed from various sources:
7197 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7198 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7199 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7200 pic16_assignRelocatableRegisters
7202 ** others have been introduced:
7203 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7204 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7206 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7208 * support/scripts/inc2h.pl: changed definition of BIT_AT
7209 to emit 'sbit at' instead of 'bit at'. This was a request.
7211 PIC16 port related preliminary changes:
7212 * gen.c: prefixed function popRegFromString with
7213 pic16_ and all references to it corrected
7214 * pcode.c: all pic16_pc_* hardware registers prefixed
7215 with underscore (_),
7216 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7217 * ralloc.c: newReg(): when register is REG_SFR then
7218 set address to rIdx,
7219 pic16_allocProcessorRegister(): marks register wasUsed=0
7220 pic16_writeUsedRegs(): added a call to assign processor
7221 registers via pic16_assignFixedRegisters
7223 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7225 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7226 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7227 variables in unused register banks. Also the SSEG is placed
7228 wherever there is enough space for it, and IDATA can be anywhere
7229 in internal RAM. For now compile using -Wl-Y[stack_size].
7230 The mem file is different for this option as well, since it
7231 makes no sense of talking about DSEG lenght.
7233 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7235 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7236 in certain cases, e.g. when ROM assignment, patch provided
7237 from Albert den Haan.
7239 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7478 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7480 * src/SDCCast.c (decorateType): disabled a transformation I added in
7481 revision 1.188 (access to fields of a structure at an absolute address);
7482 it breaks with bitfields, extern declarations, and gcse analysis.
7483 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7484 could be assigned through a pointer, so don't complain.
7485 * src/SDCCast.c (astErrors),
7487 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
7489 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

7495 pre-processor macro, i.e. -DMCU=p18f452
7496 * src/pic16/ralloc.c: renamed packRegisters to pic16_packRegisters,
7497 and modified to handle 'cast' icode similarly to '=' icode

8124 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8125 support for standard C idiom of memory mapped variables; for
8126 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8127 to xdata int at 0x1234 tempvar = 1.

8145 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8147 Fixed bug #621531 (const & volatile confusion in the type chain).
8148 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

8240 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8241 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8242 fetching of the pointer
8243 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8244 copied from genNearPointerSet()
8245 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8246 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8247 If they pop r0/r1 they must be called in the opposite order than aopOp().
8248 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8249 (resp. --stack-auto), prepared for --xstack

8260 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8262 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8263 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8264 type for bits was changed. It resulted in bit variables becoming
8265 global, which is not permitted in PIC 14 assembly output.
8267 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8269 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8282 A few small changes that speed up the peephole optimizer.
8286 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8288 Try to make the peephole optimizer smarter by maintaining
8289 an association between the assembly source code and the
8290 iCodes that originated them. Put this information to use
8291 with a new peephole rule condition "notVolatile" so that
8292 the rules can be aggressive yet still safe.
8297 * src/mcs51/peeph.def
8299 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8303 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8304 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8305 if the left or right operand symbols have the accuse flag set.
8307 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8309 Changed the type of the result of the ! (NOT) operator to char;
8310 previously it returned the same type as the source. This allows
8311 us to eliminate all the genFloatNot functions (all of its target
8312 implementations were very buggy) since !float can use the same
8315 * src/SDCCicode.c (ast2iCode): ! returns char

8324 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8325 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8326 during interrupts. Ensure WSAVE is located at a shared bank address.
8327 2. Fixed page selection in some places
8328 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8329 the registers name strings.
8330 4. Fixed "signed / unsigned compare" compiler warnings.
8331 5. The PIC port manages its own allocation of the general purpose
8332 registers, but makes no attempt to reuse them. As a result when
8333 compiling it soon runs out of general purpose registers. Some
8334 additional code was added to the files pcode.c and device.c to walk
8335 through the function call tree and rename the registers so that they
8345 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8346 genPlus() & genMinus() when the result is the same as left or right

8352 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8354 Made bitfield a distinct type from bit so that bitfields
8355 convert as per ANSI C and bits retain their traditional
8356 boolean style behaviour. Implemented bitfield support in
8364 * src/ds390/gen.c: bit v bitfield split
8365 * src/z80/gen.c: New support for bitfields
8366 * support/regression/tests/bitfields.c: reenabled z80,
8369 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8371 Rules 246.x, 247.x relate to bitfields, the others speed up
8372 access to xdata mapped I/O devices.
8374 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8376 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8378 Cleaned up genPackBits and genUnpackBits and added two helper
8379 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8380 for literal assignments in genPackBits (thanks to Frieder for
8386 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8388 Fixed bug #748310 (pointer to function type mishandled when the
8389 function name is omitted). Also fixed a SIGSEGV when a function
8390 attribute (reentrant, etc) is used on a non-function or on a
8391 function but misplaced before the parameter list.
8393 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8395 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8396 * support/Util/SDCCerr.h,

8418 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8420 Made the constant following the "interrupt" keyword optional. If
8421 omitted, the function will not automatically be given an entry
8422 in the interrupt vector table (similar to #pragma NOIV, but
8423 less syntacticly kludgy). The interrupt number is also now
8424 range checked. Also fixed a bug in the high order bit example

8438 * src/SDCCicode.c (operandOperation): rewritten some ops
8439 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8440 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8442 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8443 be re-activated by defining REDUCE_LITERALS)
8444 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8445 unsigned, but are signed by default
8446 * src/SDCCval.c (constVal): rearranged
8447 * src/SDCCval.c (valMod): preliminary fix
8448 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8490 constants are unsigned; added recognition of "u" flag for unsigned
8491 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8492 * src/SDCCval.c (valDiv, valMod): fixed signdness
8493 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8494 signedness of modulo, left and right shift

8955 messages from optionsTable when a port is not configured, added
8956 support for the PIc16 port in the ports table, when executing
8957 the compiler with no port specified on command line, a default
8958 port is selected with the new macro DEFAULT_PORT which is
8959 defined in port.h, in setDefaultOptions() linkOptions is removed
8960 from initialization assignment, since now it is a set,
8961 parseCmdLine uses setParseWithComma for linkOptions, in
8962 linkEdit() linkOptions are accessed with new function indexSet()
8963 which returns the i'th item of a set variable. See SDCCset.c, in
8964 linkEdit() when calling buildCmdLine(), added linkOptions as
8965 last argument. Now users can pass arguments to gplink via the
8966 -Wl option, main() uses pic16glue() to glue up pic16 programs

8980 gpasm complaining and test the linkage with gplink, _linkCmd and
8981 _asmCmd changed to be more gplink and gpasm friendly
8982 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8983 produced an error when parsed, peep rule 12 is added to utilize
8984 movff, but it is commented out since the pCode does not support
8985 yet a command with 2 address arguments
8987 2003-05-18 <johan AT balder>
8989 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10034 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10035 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10037 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10038 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

10048 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10050 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10052 * in \sdcc\as\mcs51\ changed these files in order to create an
10053 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10054 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10055 following files to include the previous two files: aslink.dsp,
10056 Makefile.aslink, Makefile.bcc, and Makefile.in.
10058 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10059 .adb instead of .cdb
10061 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10063 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10064 value from option --iram-size.
10066 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10068 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10071 2002-09-18 <wiml AT hhhh.org>
10073 * SDCClrange.h: exposed setFromRange() and setToRange()
10074 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10075 packRegsForAccUse() (bug 542397)
10076 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10077 multiple times and emitting the fetch operations more than once
10078 added aopGetUsesAcc() function to allow binary operators to
10079 fetch their operands in the correct order; made genMinus() emit
10080 compact code for X = LITERAL - Y
10082 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10083 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10084 sprintf() in line 1267.
10086 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10087 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10090 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10091 Changes to aslink (All the changes are marked with 'JCF'):
10093 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10096 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10097 area BSEG. Also moves, if possible, the DATA area down into the internal
10098 ram so more space is available.
10100 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10103 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10104 not bytes. Function summary() which creates a memory usage summary
10105 file with extension .mem. Reports of overlaping stack and small stack
10106 size. If the space for the stack is less than 16 bytes aslink trows a
10109 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10110 the 8051. Option 'y' for memory summary output file.
10112 Changes to sdcc (All the changes are marked with 'JCF'):
10114 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10116 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10117 overlaying area for it (uses RegBankUsed[4]).
10119 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10120 bank zero as used by default. By default aslink locates the stack
10121 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10122 the creation of the .mem file. Delegates the allocation of data area
10123 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10124 the begining of the stack area to aslink.
10126 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10127 glue() in SDCCglue.c creates an area for it.
10129 2002-09-03 Borut Razem <borut.razem AT siol.net>
10130 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10131 sdcc/src/pic/glue.c:
10132 introduced atexit() handler for teporay files removal in case of
10133 errors, assertions, ...
10135 2002-08-29 Borut Razem <borut.razem AT siol.net>
10136 * sdcc/support/cpp2/auto-host_vc_in.h:
10137 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10138 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10139 Maybe there is a similar problem with BORLANDC? It should be checked!
10141 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10142 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10143 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10144 was not executed, and the compiler (cl) launched a warning:
10145 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10147 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10148 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10150 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10151 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10153 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10154 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10155 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10156 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10157 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10158 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10159 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10160 - added Release configuration in VS projects
10161 - review of compiler an linker options
10162 - VC .exe files are generated in bin_vc directory, not to interfere
10163 with binaries generated from other projects (cygwin, mingw, bcc ...)
10165 * sdcc/src/yacc.dsp: added
10167 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10168 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10169 and insert the version number definitions from .version
10171 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10173 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10174 added - genarate auto-host.h using auto-host_vc_in.h as template
10177 removed from CVS, generated automatically
10179 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10180 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10182 2002-08-11 Borut Razem <borut.razem AT siol.net>
10183 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10185 2002-08-10 Borut Razem <borut.razem AT siol.net>
10186 * src/SDCCmain.c (main):
10187 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10188 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10189 The consequence was that some temporary files were not removed.
10192 unification of code in functions tempfilename() and tempfile():
10193 function tempnam() is defined in Visual Studio 6.0 and .NET
10195 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10197 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10198 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10199 - removed compiler command line option /WX: Treats all warnings as errors
10200 - update a list of source files, included into the project
10202 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10203 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10204 changed project type to Generic Project so that can be correcly converted to VS.NET project
10206 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10208 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10210 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10212 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10213 added return 0 statements after assert() to make compiler happy
10215 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10216 added newline in the def file to keep MSC compiler satisfied
10218 * sdcc/src/z80/gen.c:
10219 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10220 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10221 - solved MSC error in function aopDump()
10223 * sdcc_vc.h: define PREFIX as "\\sdcc"
10225 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10226 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
10228 2002-06-22 Scott Dattalo <scott AT dattalo.com>
10229 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10230 - Rewrote the register banking algorithm.
10231 - Added pCode live-range analysis to registers (for now, only non-used and
10232 singly-used registers optimized away)
10234 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10236 * 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.

10253 * device/lib/z80/printf.c (sprintf): Added.
10255 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
10257 * src/z80/peeph.def: Added transpose redundent load rule.
10259 * src/z80/main.c: Added force callee saves for jaune.
10261 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10263 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10265 2002-03-28 Johan Knol <johan AT balder>
10267 * src/SDCCval.c: fixed bug #532436
10269 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10271 Added "char *Processor" field to the port structure.
10274 Added -p option. Allows port dependent processor to be specified.
10277 Initialized the new field char *Processor field to NULL in all ports
10280 Compiler generated registers for interrupt context saving
10281 were not getting allocated.
10283 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10286 Fixed left shift. Will promote the left side of a left shift
10287 if a) left shifting more than size of operand or b) when assigned
10288 to something size > size of left side
10290 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10292 tons of changes. Register allocation has been
10293 rewritten. Added customization for the various PICs. Flow
10294 analysis is restructured. ...
10296 * src/pic/device.h:
10299 * src/pic/device.c:
10300 Added. device.c is a PIC port hack to accomodate variations
10303 2002-03-13 Michael Hope <michaelh AT vroom>
10305 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10307 2002-03-04 johanknol <johanknol AT manik>
10309 * /src/SDCCval.c: fixed
10311 const unsigned char arr[][2] = { { 0, 1 } };

10398 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10400 * sdcc/src/SDCCloop.c:
10401 Previous fix was not good. basic blocks that have "break" or "return" are
10402 not really partof a loop , but live ranges used in these blocks should
10403 be live thru the entire loop, so set partOfLoop but don't add them to
10406 2002-02-21 <johan AT FRIJA>
10408 * src/SDCCcse.c: fixed bug #514308
10410 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10413 Fixed BUG #519583. If a conditional block ended in a return/break
10414 statement inside a loop, it was not being considered part of the loop.
10416 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10418 2002-02-10 Karl Bongers <karl AT turbobit.com>

10422 with lots of comments and notes.
10424 * device/examples/test2.c:
10425 Fix bug, "red" variable not being initialized(compiler complained).
10427 * device/examples/Makefile, examples/test3.c:
10428 Add Makefile in device/examples folder, compiles test3.c
10429 for use as a multiple module SDCDB test case.
10431 * sim/ucsim/cmd.src/cmdset.cc:
10432 Took out debug printfs in ucsim "next" command.
