2179 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2181 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2182 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2184 One basic decision: e.g. src/clean.mk includes further files. In order
2185 to make this work there are two solutions:
2186 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2187 run configure on them. This way they can use
2188 'include $(srcdir)/port-clean.mk'
2189 - always include clean.mk by the Makefile at the same level. To avoid
2190 that `make clean` tries to include and build Makefile.dep the
2191 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2192 implemented, because now even `make uninstall` doesn't create
2193 Makefile.in. clean.mk could be eliminated by pasting it in
2196 * debugger/mcs51/Makefile.in: build own objects from library sources
2197 (SLIB, SDCC) in current directory
2199 * configure, configure.in: renamed --disable-device-lib-build in
2200 --disable-device-lib; added --enable-doc, the required tools are
2201 searched by configure; added result message; the toolchain for the
2202 belonging ports are now only built, if the port is enabled.
2204 * support/regression/*: all output is written in directory gen, because
2205 the fwk and ports directories don't livet in the build tree using vpath
2207 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2208 --disable-device-lib, added --enable-doc, added section VPATH
2210 * sim/ucsim/configure.in,
2211 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2212 z80 are enabled by default
2214 2006-04-24 Raphael Neider <rneider AT web.de>
2216 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2217 to config word, "pic14_"-prefixed some extern functions
2218 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2219 config word has been found
2220 * src/pic/device.h: added prototypes
2221 * src/pic/pcode.c: added "pic14_"-prefix where needed
2222 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic

2234 2006-04-24 Raphael Neider <rneider AT web.de>
2236 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
2237 registers that have not been assigned proper liveranges,
2238 fixes #1469504 and #1474602,
2239 (pCodeRegOptimizeRegUsage): fixed typo in comment

2529 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2530 call to allocReg, not by manually allocating a new one,
2531 (pic16_assignRegisters): now before going through the register
2532 allocating functions mark all registers as free. This eliminates some
2533 side effects resulting from peephole parser done earlier in the backbone

2601 _main (this should take care the --main-return command line option in
2603 (genOr): removed some legacy pic-port instructions,
2604 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2605 performing operations with SFR's causes data to be written more than
2606 once to each SFR. Perhaps SFRs should be handled in special cases...
2607 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2609 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2610 into account for stack starting position,
2611 (struct OPTIONS pic16_optionsTable): added command line argument
2612 --extended or -y for Extended Instruction Support,
2613 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2614 (deassignLRs): *** perhaps the most important change, old 'for' code
2615 (commented out for reference), didn't account for some registers which
2616 were left marked 'not free' after a pointer operation. The change
2617 reduces register usage a lot in some cases

4892 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4893 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4894 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4895 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4896 always available in leading double underscore form. The C99 support is
4897 mostly missing, but it's a start.

4977 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4979 * device/lib/printf_large.c: removed inline assembly for portability and
4980 readability. Use printf_fast if speed or size are more important.
4981 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4982 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4984 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4986 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4987 prevent compiler warning
4989 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4991 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4992 moved to level 0 and declared as static. Also they are explicit
4993 placed in access bank. This was necessery because some times they
4994 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4995 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4996 optimizations. Currently only compare to unsigned char is implemented,
4997 * src/pic16/gen.c: added fReturnIdx array,
4998 * (struct resolvedIfx) is moved to gen.h and made public,
4999 * (struct _G): added sregsAlloc and sregsAllocSet fields,
5000 * (aopForSym): added an optimization to directly store in stack of
5001 the operand of a SEND iCode,
5002 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
5003 but as registers instead (AOP_REG) using the fReturnIdx array,
5004 * (pic16_freeAsmop): remove the freed register from the
5005 _G.sregsAlloc field,
5006 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
5007 a compare of 'WREG',
5008 * (pic16_popGetTempRegCond): changed function prototype, now
5009 function takes also a bitVector argument v which holds the current
5010 set of registers that are allocated for stack access by aopForSym,
5011 registers allocated in aopForSym for accessing stack symbols are not
5012 any more part of the functions usedRegs field,
5013 * (genCall): some times aopOp is called for a stack variable to be
5014 send, aopForSym might perform the push, if this is true make sure
5015 that genCall doesn't push the variable twice by testing _G.resDirect,
5016 * (genFunction): changed testing for unspecified interrupt number
5017 from 256 to INTNO_UNSPEC,
5018 * modified selection scheme of frame pointer generation. Previously
5019 if function did use local registers a frame pointer was generated,
5020 now a frame pointer is generated only if function has arguments
5021 (that need PLUSW2 register access), or has stack arguments, or the
5022 compiler is not instructed to omit the frame pointer,
5023 * (genEndFunction): before restoring local registers that were saved
5024 in the function preamble, also restore the registers that *might*
5025 have been allocated for stack access,
5026 * (genRet): removed some old comments,
5027 * (genCmp, the active (RN's) version): added a call to the
5028 pic16_genCmp_special function to perform the compare with a more
5029 robust and optimized way,
5030 * (genInline): a feature has been added in inline code generation,
5031 which allows a wildcard variable substitution when writing inline
5032 assembly. Code is incomplete and experimental therefore undocumented,
5033 * (genCast): changed order of aopOp for result and right to allow
5034 aopForSym to directly load the result if possible,
5035 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
5036 perform an optimized compare on some selected special occasions,
5037 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
5038 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
5039 generate an IVT any more,
5040 * src/pic16/main.c (pic16_optionsTable): added command line option
5042 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
5043 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
5045 * src/pic16/NOTES: Raphael Neider added in list of active developers
5046 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
5047 jumptable_end to prevent bug #,
5048 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
5049 inCond and outCond fields,
5050 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
5051 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
5052 turn off register spilling,
5053 * (packRegsForOneUse): synced with other ports' versions although it
5054 is not used currently,
5055 * (pic16_packRegisters): added an optimization while reading
5056 structure bitfields, some registers may be saved (malloc code is
5057 decreased by 80 bytes)
5059 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
5061 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
5062 left is a bitfield, if yes, then don't optimize assignment. Perhaps
5063 this can be optimized more?
5065 2005-03-10 Raphael Neider <rneider AT web.de>
5067 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
5068 genNearPointerGet): (hopefully) fixed access to bitfields via
5069 pointers (p->bitN = x; and x = p->bitN; failed)

5115 to keep the correct label reference count when adding/removing references
5116 to labels. A peephole file using this is appended to patch #1144962.

5701 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5703 Adding support for replacing ljmps with sjmps in jumptables
5704 generated for switch statements. For now you need to set the
5705 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5706 Now 4 algorithms for mcs51 jumptable generation are used:
5707 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5708 addresses loaded pc-relative for up to 112 cases and stack-pushing
5709 target addresses loaded with offset from dptr for up to 256 cases.

5739 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5741 * added libc directory. The current version of LibC contains string
5742 functions, ctype functions and macros and some functions of the
5743 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5744 be extensively tested in the future. Standard disclaimer here.
5745 Library is not automatically build yet. But one can build it by
5746 invoking 'make' inside the libc directory.

5757 * (pic16_storeForReturn): optimized return of 0,
5758 * (genCmp): experimental code for new genCmp which uses PIC18's
5759 special compare&skip instructions. Initial tests fail some times
5760 with variables grater than 1 byte in size, so new code is disabled,
5761 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5763 * (genCast): began a fix to optimize the casting of a bit to another
5764 bit, now assigning a bitfield to another bitfield will fail, sorry,

5775 caused stop processing pCodes after a inline assembly block,
5776 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5778 registers when it shouldn't,
5779 * src/pic16/ralloc.c (allocReg): add preliminary support for
5780 supporting a limited set of temporary registers,
5782 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5784 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

8673 virus/worm forged address usage.
8675 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
8677 Fixed promotion, it should be done on AST level:

8701 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
8703 * src/SDCCast.c: added an additional type flow in decorateType() of
8704 opposite direction, see feature request #860006; it's enabled at runtime
8705 by setting the environment variable SDCC_NEWTYPEFLOW
8706 * src/SDCCast.h: changed prototype of decorateType()
8707 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
8708 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
8709 'char' to 'int' can be omitted, if both operands are 'unsigned char';
8710 see feature request #877103

8739 * src/pic/ralloc.h: applied patch from Slade Rich;
8740 added support for multiple code pages and multiple RAM banks on the
8741 PIC 14 port. The ASM files now no longer simply assume all the
8742 code / RAM are in the same page / bank. This means the linker can
8743 safely allocate code/RAM of separate ASM files to different pages/banks.
8744 * doc/sdccman.lyx: added Slade's tips
8745 * src/mcs51/peeph.def: fixed bug #880768

8787 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8789 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8790 loaded with the linker search paths (-L arguments) and the libraries
8791 to be linked with the current source (-l arguments). Changes
8792 currently will affect only the pic16 port.
8793 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8794 include path the port specific paths and port specific libraries,
8795 * gplink command now contains the $3 argument,
8796 * src/pic16/device.h,
8797 * src/pic16/device.c,: structure PIC_device is made public and
8798 renamed to PIC16_device, the same for variable Pics which is renamed

8813 Documenting changes from previous commits.
8814 * configure.in (version 1.56),
8815 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8816 when generating output files to configure the pic16 library,
8817 but now I've commented it out, since gputils aren't installed in the
8818 SF compile farm, so library won't compile
8820 * device/lib/Makefile.in (version 1.56): initially I've added in
8821 target 'all' the prerequestive 'model-pic16' so it compiled the
8822 pic16 library, but now I've commented it out for the same reasons
8824 * added targets 'model-pic16' and 'objects-pic16' to compile the
8826 * added target 'port-specific-objects-pic16' to handle the
8827 generated libraries and copy them into the build/ directory
8828 * added target 'clean-intermediate-pic16' to clean intermediate
8829 files into pic16 directory
8830 * in target 'installdirs' added line to create directory pic16 in
8831 the installation path
8833 * device/include/Makefile.in (version 1.11): in target 'install'
8834 added lines to copy all header files to installation path,
8835 * in target 'installdirs' added line create directory for pic16
8836 headers in the installation path

8851 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8852 option so that it actually works. Made it specific to the z80, since
8853 the gbz80 doesn't have these kinds of I/O ports.
8855 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8857 * device/include/z180.h,

8881 via literal number. The symbol is placed in the corresponding
8882 position of the data ram
8883 * (pic16_dump_section): relocatable and absolute uninitialized
8884 data are now emitted in sorted order to reduce section naming,
8885 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8886 weren't marked as being in the access bank,
8888 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8890 Added portion of GNU PIC Library under the directory
8891 device/include/pic16 and device/lib/pic16. These files
8892 contain the declarations of SFRs for the PIC18Fxx2 devices.
8893 The directory is initialized via configure from toplevel.

8923 all over. Telling LaTeX to be less strict with word spacing
8924 to better keep the right margin. Changed some notes about
8925 maintainance of the ports in section 3.2.1 - is it OK like this?

9121 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
9123 PIC16 port related changes:
9124 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
9125 added variable stackPos,
9127 * gen.c: genCall, assignResultValue: added support for
9128 pushing/retrieving function parameters to/from stack,
9129 genFunction,genEndFunction: setup stack frame for the
9131 genAddrOf: will be changed according to bug 863624
9133 * added files genutils.c and genutils.h which contain gen*
9134 debugged and optimised functions extracted from gen.c
9136 * glue.c: added variable 'externs' which holds extern symbols,
9137 pic16emitRegularMap: is modified to properly handle relocatable
9138 symbols under the new scheme,
9139 pic16createInterruptVect: is modified
9140 pic16printPublics: is modified to emit 'global' assembler directives,
9141 added pic16_printExterns to print extern symbols,
9142 pic16glue: initializes stack/frame pointer in the beginning of
9143 the assembly output. Temporary hack, will be corrected later,
9144 because gplink yet does not support stack and SDCC does not
9145 yet support a type of crt0.o object to create the final binary.
9147 * Removed many lines that contain 8051 legacy code.
9148 * The code is finally placed under a 'code' directive.
9149 * Added port specific options.
9151 * _process_pragma: simplified since now we do not need *special*
9152 include file to define SFR registers. But a separate header
9153 will be needed. This will be developed later.
9154 * _pic16_parseOptions: added, parses port specific options:
9155 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9156 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9157 --preplace-udata-with=
9159 * _pic16_setDefaultOptions: modified to initialize section names,
9160 but hack is temporarly out of order since it needs improvement.
9161 * _pic16_genAssemblerPreamble: configuration words are emitted by
9162 their address instead of their name. This part is incomplete and
9163 supports only the 18Fxx2 devices. Other devices will emit an error
9164 during assembly since they do not contain the same set of config
9166 * _pic16_genIVT: is modified,
9168 * pcode.c: added definitions for some hardware registers that are needed
9170 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9171 All PCI entries are updated. Now LFSR is supported.
9172 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9173 * added pic16_newpCodeOpLit2 to support instructions with
9174 two literal arguments
9175 * pic16_pCode2str: corrected code that emits assembler instructions
9176 with two literal operands and those that have an access bit modifier
9177 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9178 this fixes a bug which caused some labels to be lost, when an
9179 assembler directive was added, i.e. banksel,
9180 * pic16_FixRegisterBanking: improved logic that causes the insertion
9182 * InlineFunction: functions that are called once, are not any more
9183 inlined. This can be a port option in the future,
9185 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9187 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9188 hold the corresponding uninitialized symbols,
9189 * pic16_allocProcessorRegister: registers have explicit marked the
9191 * pic16_allocInternalRegister: registers are explicit marked as
9193 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9194 processing list, so bit registers were lost,
9197 * ralloc.h: added field 'accessBank' and original symbol operand
9198 in register definition,
9199 * removed the field isMapped from register definition,
9201 ** Several functions have been removed from various sources:
9202 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9203 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9204 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9205 pic16_assignRelocatableRegisters
9207 ** others have been introduced:
9208 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9209 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9211 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9213 * support/scripts/inc2h.pl: changed definition of BIT_AT
9214 to emit 'sbit at' instead of 'bit at'. This was a request.
9216 PIC16 port related preliminary changes:
9217 * gen.c: prefixed function popRegFromString with
9218 pic16_ and all references to it corrected
9219 * pcode.c: all pic16_pc_* hardware registers prefixed
9220 with underscore (_),
9221 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9222 * ralloc.c: newReg(): when register is REG_SFR then
9223 set address to rIdx,
9224 pic16_allocProcessorRegister(): marks register wasUsed=0
9225 pic16_writeUsedRegs(): added a call to assign processor
9226 registers via pic16_assignFixedRegisters
9228 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9230 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9231 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9232 variables in unused register banks. Also the SSEG is placed
9233 wherever there is enough space for it, and IDATA can be anywhere
9234 in internal RAM. For now compile using -Wl-Y[stack_size].
9235 The mem file is different for this option as well, since it
9236 makes no sense of talking about DSEG lenght.
9238 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9240 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9241 in certain cases, e.g. when ROM assignment, patch provided
9242 from Albert den Haan.

9483 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9485 * src/SDCCast.c (decorateType): disabled a transformation I added in
9486 revision 1.188 (access to fields of a structure at an absolute address);
9487 it breaks with bitfields, extern declarations, and gcse analysis.
9488 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9489 could be assigned through a pointer, so don't complain.
9490 * src/SDCCast.c (astErrors),

9594 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
9595 uninitialized variables) for the mcs51. Set environment variable

9597 xdata initialization slightly shorter
9599 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10231 and JUMPTABLE iCodes properly now (worked by accident before)
10232 * src/mcs51/gen.c (leftRightUseAcc),
10233 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
10234 iCode properly now. Use getSize instead of nRegs since a & b
10235 aren't part of the nRegs tally.
10237 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
10239 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

10249 copied from genNearPointerSet()
10250 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10251 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10252 If they pop r0/r1 they must be called in the opposite order than aopOp().
10253 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10254 (resp. --stack-auto), prepared for --xstack
10256 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

10265 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10267 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10268 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10269 type for bits was changed. It resulted in bit variables becoming
10270 global, which is not permitted in PIC 14 assembly output.
10272 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10274 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10276 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10278 Z80 and MCS51 linkers complaint if a public symbol is defined

10285 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10287 A few small changes that speed up the peephole optimizer.
10291 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10293 Try to make the peephole optimizer smarter by maintaining
10294 an association between the assembly source code and the
10295 iCodes that originated them. Put this information to use
10296 with a new peephole rule condition "notVolatile" so that
10297 the rules can be aggressive yet still safe.
10302 * src/mcs51/peeph.def
10304 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10308 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10309 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10310 if the left or right operand symbols have the accuse flag set.
10312 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10314 Changed the type of the result of the ! (NOT) operator to char;
10315 previously it returned the same type as the source. This allows
10316 us to eliminate all the genFloatNot functions (all of its target
10317 implementations were very buggy) since !float can use the same
10320 * src/SDCCicode.c (ast2iCode): ! returns char

10329 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10330 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10331 during interrupts. Ensure WSAVE is located at a shared bank address.
10332 2. Fixed page selection in some places
10333 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10334 the registers name strings.
10335 4. Fixed "signed / unsigned compare" compiler warnings.
10336 5. The PIC port manages its own allocation of the general purpose
10337 registers, but makes no attempt to reuse them. As a result when
10338 compiling it soon runs out of general purpose registers. Some
10339 additional code was added to the files pcode.c and device.c to walk
10340 through the function call tree and rename the registers so that they
10350 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10351 genPlus() & genMinus() when the result is the same as left or right
10353 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10357 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10359 Made bitfield a distinct type from bit so that bitfields
10360 convert as per ANSI C and bits retain their traditional
10361 boolean style behaviour. Implemented bitfield support in
10369 * src/ds390/gen.c: bit v bitfield split
10370 * src/z80/gen.c: New support for bitfields
10371 * support/regression/tests/bitfields.c: reenabled z80,
10374 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10376 Rules 246.x, 247.x relate to bitfields, the others speed up
10377 access to xdata mapped I/O devices.
10379 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10381 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10383 Cleaned up genPackBits and genUnpackBits and added two helper
10384 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10385 for literal assignments in genPackBits (thanks to Frieder for
10391 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10393 Fixed bug #748310 (pointer to function type mishandled when the
10394 function name is omitted). Also fixed a SIGSEGV when a function
10395 attribute (reentrant, etc) is used on a non-function or on a
10396 function but misplaced before the parameter list.
10398 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10400 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10401 * support/Util/SDCCerr.h,
10402 * support/Util/SDCCerr.c: Added func attr misuse error msg
10404 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10406 Fixed bug #787649 by anonymous
10407 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10408 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10410 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10423 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10425 Made the constant following the "interrupt" keyword optional. If
10426 omitted, the function will not automatically be given an entry
10427 in the interrupt vector table (similar to #pragma NOIV, but
10428 less syntacticly kludgy). The interrupt number is also now
10429 range checked. Also fixed a bug in the high order bit example

10443 * src/SDCCicode.c (operandOperation): rewritten some ops
10444 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
10445 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10447 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10448 be re-activated by defining REDUCE_LITERALS)
10449 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10450 unsigned, but are signed by default
10451 * src/SDCCval.c (constVal): rearranged
10452 * src/SDCCval.c (valMod): preliminary fix
10453 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10493 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10494 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10495 constants are unsigned; added recognition of "u" flag for unsigned
10496 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10497 * src/SDCCval.c (valDiv, valMod): fixed signdness

10959 added if/endif conditional macros to remove options help
10960 messages from optionsTable when a port is not configured, added
10961 support for the PIc16 port in the ports table, when executing
10962 the compiler with no port specified on command line, a default
10963 port is selected with the new macro DEFAULT_PORT which is
10964 defined in port.h, in setDefaultOptions() linkOptions is removed
10965 from initialization assignment, since now it is a set,
10966 parseCmdLine uses setParseWithComma for linkOptions, in
10967 linkEdit() linkOptions are accessed with new function indexSet()
10968 which returns the i'th item of a set variable. See SDCCset.c, in
10969 linkEdit() when calling buildCmdLine(), added linkOptions as
10970 last argument. Now users can pass arguments to gplink via the
10971 -Wl option, main() uses pic16glue() to glue up pic16 programs

10985 gpasm complaining and test the linkage with gplink, _linkCmd and
10986 _asmCmd changed to be more gplink and gpasm friendly
10987 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10988 produced an error when parsed, peep rule 12 is added to utilize
10989 movff, but it is commented out since the pCode does not support
10990 yet a command with 2 address arguments
10992 2003-05-18 <johan AT balder>
10994 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

12042 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12043 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

12046 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
12047 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
12049 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>

12052 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
12053 * src/mcs51/main.c: removed {bindir}{sep} from aslink
12055 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12057 * in /sdcc/as/mcs51/ changed these files in order to create an
12058 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
12059 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
12060 following files to include the previous two files: aslink.dsp,
12061 Makefile.aslink, Makefile.bcc, and Makefile.in.
12063 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
12064 .adb instead of .cdb
12066 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12068 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
12069 value from option --iram-size.
12071 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12073 * /sdcc/as/mcs51/lklist.c: added boundary check before using
12076 2002-09-18 <wiml AT hhhh.org>
12078 * SDCClrange.h: exposed setFromRange() and setToRange()
12079 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
12080 packRegsForAccUse() (bug 542397)
12081 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
12082 multiple times and emitting the fetch operations more than once
12083 added aopGetUsesAcc() function to allow binary operators to
12084 fetch their operands in the correct order; made genMinus() emit
12085 compact code for X = LITERAL - Y
12087 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12088 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
12089 sprintf() in line 1267.
12091 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12092 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
12095 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
12096 Changes to aslink (All the changes are marked with 'JCF'):
12098 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
12101 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
12102 area BSEG. Also moves, if possible, the DATA area down into the internal
12103 ram so more space is available.
12105 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
12108 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
12109 not bytes. Function summary() which creates a memory usage summary
12110 file with extension .mem. Reports of overlaping stack and small stack
12111 size. If the space for the stack is less than 16 bytes aslink trows a
12114 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
12115 the 8051. Option 'y' for memory summary output file.
12117 Changes to sdcc (All the changes are marked with 'JCF'):
12119 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
12121 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
12122 overlaying area for it (uses RegBankUsed[4]).
12124 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
12125 bank zero as used by default. By default aslink locates the stack
12126 (equivalent to --stack-after-data). Pass option 'y' to aslink for
12127 the creation of the .mem file. Delegates the allocation of data area
12128 to aslink (it is not longer 0x30 by default). If --stack-loc passes
12129 the begining of the stack area to aslink.
12131 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
12132 glue() in SDCCglue.c creates an area for it.
12134 2002-09-03 Borut Razem <borut.razem AT siol.net>
12135 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
12136 sdcc/src/pic/glue.c:
12137 introduced atexit() handler for teporay files removal in case of
12138 errors, assertions, ...
12140 2002-08-29 Borut Razem <borut.razem AT siol.net>
12141 * sdcc/support/cpp2/auto-host_vc_in.h:
12142 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
12143 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
12144 Maybe there is a similar problem with BORLANDC? It should be checked!
12146 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
12147 corrected improper use of assert: the assignment to clr variable was done inside the assert.
12148 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
12149 was not executed, and the compiler (cl) launched a warning:
12150 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
12152 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
12153 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
12155 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
12156 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
12158 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12159 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12160 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12161 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12162 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12163 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12164 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12165 - added Release configuration in VS projects
12166 - review of compiler an linker options
12167 - VC .exe files are generated in bin_vc directory, not to interfere
12168 with binaries generated from other projects (cygwin, mingw, bcc ...)
12170 * sdcc/src/yacc.dsp: added
12172 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12173 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12174 and insert the version number definitions from .version
12176 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12178 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
12179 added - genarate auto-host.h using auto-host_vc_in.h as template
12182 removed from CVS, generated automatically
12184 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
12185 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12187 2002-08-11 Borut Razem <borut.razem AT siol.net>
12188 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12190 2002-08-10 Borut Razem <borut.razem AT siol.net>
12191 * src/SDCCmain.c (main):
12192 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12193 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12194 The consequence was that some temporary files were not removed.
12197 unification of code in functions tempfilename() and tempfile():
12198 function tempnam() is defined in Visual Studio 6.0 and .NET
12200 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12202 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12203 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
12204 - removed compiler command line option /WX: Treats all warnings as errors
12205 - update a list of source files, included into the project
12207 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12208 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12209 changed project type to Generic Project so that can be correcly converted to VS.NET project
12211 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12213 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12215 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12217 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12218 added return 0 statements after assert() to make compiler happy
12220 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12221 added newline in the def file to keep MSC compiler satisfied
12223 * sdcc/src/z80/gen.c:
12224 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12225 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12226 - solved MSC error in function aopDump()
12228 * sdcc_vc.h: define PREFIX as "\\sdcc"
12230 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
12231 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
12233 2002-06-22 Scott Dattalo <scott AT dattalo.com>
12234 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
12235 - Rewrote the register banking algorithm.
12236 - Added pCode live-range analysis to registers (for now, only non-used and
12237 singly-used registers optimized away)
12239 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
12241 * 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.
12243 2002-05-10 Scott Dattalo <scott AT dattalo.com>

12256 2002-04-15 Michael Hope <michaelh AT vroom>
12258 * device/lib/z80/printf.c (sprintf): Added.
12260 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
12262 * src/z80/peeph.def: Added transpose redundent load rule.
12264 * src/z80/main.c: Added force callee saves for jaune.
12266 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
12268 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
12270 2002-03-28 Johan Knol <johan AT balder>
12272 * src/SDCCval.c: fixed bug #532436
12274 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12276 Added "char *Processor" field to the port structure.
12279 Added -p option. Allows port dependent processor to be specified.
12282 Initialized the new field char *Processor field to NULL in all ports
12285 Compiler generated registers for interrupt context saving
12286 were not getting allocated.
12288 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
12291 Fixed left shift. Will promote the left side of a left shift
12292 if a) left shifting more than size of operand or b) when assigned
12293 to something size > size of left side
12295 2002-03-14 Scott Dattalo <scott AT dattalo.com>
12297 tons of changes. Register allocation has been
12298 rewritten. Added customization for the various PICs. Flow
12299 analysis is restructured. ...
12301 * src/pic/device.h:
12304 * src/pic/device.c:
12305 Added. device.c is a PIC port hack to accomodate variations
12308 2002-03-13 Michael Hope <michaelh AT vroom>
12310 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
12312 2002-03-04 johanknol <johanknol AT manik>
12314 * /src/SDCCval.c: fixed
12316 const unsigned char arr[][2] = { { 0, 1 } };
12317 t18.c:1: error: Initializer element is not constant

12403 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12405 * sdcc/src/SDCCloop.c:
12406 Previous fix was not good. basic blocks that have "break" or "return" are
12407 not really partof a loop , but live ranges used in these blocks should
12408 be live thru the entire loop, so set partOfLoop but don't add them to
12411 2002-02-21 <johan AT FRIJA>
12413 * src/SDCCcse.c: fixed bug #514308
12415 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
12418 Fixed BUG #519583. If a conditional block ended in a return/break
12419 statement inside a loop, it was not being considered part of the loop.
12421 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
12423 2002-02-10 Karl Bongers <karl AT turbobit.com>

12427 with lots of comments and notes.
12429 * device/examples/test2.c:
12430 Fix bug, "red" variable not being initialized(compiler complained).
12432 * device/examples/Makefile, examples/test3.c:
12433 Add Makefile in device/examples folder, compiles test3.c
12434 for use as a multiple module SDCDB test case.
12436 * sim/ucsim/cmd.src/cmdset.cc:
12437 Took out debug printfs in ucsim "next" command.
12439 * sim/ucsim/xa.src:
12440 Karl and Johan start ucsim XA support. Most dissassembly working,
12441 about 75% emulation done(plenty of work remaining).
12443 * sim/ucsim/z80.src:
