2005 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2007 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2008 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2010 One basic decision: e.g. src/clean.mk includes further files. In order
2011 to make this work there are two solutions:
2012 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2013 run configure on them. This way they can use
2014 'include $(srcdir)/port-clean.mk'
2015 - always include clean.mk by the Makefile at the same level. To avoid
2016 that `make clean` tries to include and build Makefile.dep the
2017 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2018 implemented, because now even `make uninstall` doesn't create
2019 Makefile.in. clean.mk could be eliminated by pasting it in
2022 * debugger/mcs51/Makefile.in: build own objects from library sources
2023 (SLIB, SDCC) in current directory
2025 * configure, configure.in: renamed --disable-device-lib-build in
2026 --disable-device-lib; added --enable-doc, the required tools are
2027 searched by configure; added result message; the toolchain for the
2028 belonging ports are now only built, if the port is enabled.
2030 * support/regression/*: all output is written in directory gen, because
2031 the fwk and ports directories don't livet in the build tree using vpath
2033 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2034 --disable-device-lib, added --enable-doc, added section VPATH
2036 * sim/ucsim/configure.in,
2037 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2038 z80 are enabled by default
2040 2006-04-24 Raphael Neider <rneider AT web.de>
2042 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2043 to config word, "pic14_"-prefixed some extern functions

2045 config word has been found
2046 * src/pic/device.h: added prototypes
2047 * src/pic/pcode.c: added "pic14_"-prefix where needed

2311 implemented patch 1120823 Thanks to Willy De la Court (normal
2312 interrupts need an interrupt number now if they are made critical),
2313 and enabled nesting of critical functions though not for gbz80
2314 (genCritical, genEndCritical): added functions
2315 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2316 * src/z80/mappings.i: added "ei" to all mappings

2328 the left operand is shorter than the result (c* = lit-c* + int),
2330 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2333 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2335 * src/.version: increased version number to 2.5.5
2336 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2337 linking is done manually in pic16 port's _linkEdit,
2338 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2339 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2340 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2341 allocate asmop as AOP_ACC,
2342 (aopForRemat): added parameter 'bool result' in function declaration,
2343 (pic16_aopGet): return AOP_ACC when accessing WREG,
2344 (pic16_popGetTempReg): minor modification,

2355 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2356 call to allocReg, not by manually allocating a new one,
2357 (pic16_assignRegisters): now before going through the register
2358 allocating functions mark all registers as free. This eliminates some
2359 side effects resulting from peephole parser done earlier in the backbone
2361 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2411 2006-03-06 Borut Razem <borut.razem AT siol.net>
2413 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2414 made the linker quiet

2419 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2420 which dumps before the function entry point a data byte which represents
2421 the number of the local variables used by the specified function, added
2422 'xinst' for initial support for Extended Instruction Support,
2423 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2424 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2425 port->fun_prefix anymore (may change later),
2426 (genFunction, genEndFunction): do not store/restore local registers for
2427 _main (this should take care the --main-return command line option in
2429 (genOr): removed some legacy pic-port instructions,
2430 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2431 performing operations with SFR's causes data to be written more than
2432 once to each SFR. Perhaps SFRs should be handled in special cases...
2433 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2435 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2436 into account for stack starting position,

2438 --extended or -y for Extended Instruction Support,
2439 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2440 (deassignLRs): *** perhaps the most important change, old 'for' code
2441 (commented out for reference), didn't account for some registers which
2442 were left marked 'not free' after a pointer operation. The change
2443 reduces register usage a lot in some cases
2445 2006-03-04 Borut Razem <borut.razem AT siol.net>

4704 2005-03-26 Raphael Neider <rneider AT web.de>
4706 * src/pic16/gen.c (genSkipc): fixed semantics (execute branch
4707 if condition == CARRY)
4708 * (genCmp): adapted to new genSkipc semantics
4709 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
4710 on rIfx (genCmp was broken)
4712 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4714 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
4715 * src/z80/main.c (_keywords[]),
4716 * src/SDCCglobal.h (struct options),
4718 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4719 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4720 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4721 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4722 always available in leading double underscore form. The C99 support is
4723 mostly missing, but it's a start.
4724 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4725 reserved identifier "__data".
4727 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
4729 * src/mcs51/peeph.def: fixed bug 1170013

4737 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
4740 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4742 * src/port.h (struct PORT),
4743 * src/avr/ralloc.c (avr_assignRegisters),
4745 * src/ds390/ralloc.c (ds390_assignRegisters),
4747 * src/hc08/ralloc.c (hc08_assignRegisters),

4769 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
4770 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
4771 immedDom() returning wrong block; probably fixes bug #1160833)
4773 2005-03-20 Borut Razem <borut.razem AT siol.net>
4775 * support/scripts/inc2h.pl: WIN32 port
4777 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4779 * device/lib/makefile.in: added abs.c and labs.c
4781 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4783 * device/include/stdint.h: added
4784 * device/lib/abs.c: added
4785 * device/lib/labs.c: added
4786 * device/include/stdlib.h: added abs() and labs() prototypes

4801 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4803 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4805 * device/lib/printf_large.c: removed inline assembly for portability and
4806 readability. Use printf_fast if speed or size are more important.
4807 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4808 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4810 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4812 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4813 prevent compiler warning
4815 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4817 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4818 moved to level 0 and declared as static. Also they are explicit
4819 placed in access bank. This was necessery because some times they
4820 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4821 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4822 optimizations. Currently only compare to unsigned char is implemented,
4823 * src/pic16/gen.c: added fReturnIdx array,
4824 * (struct resolvedIfx) is moved to gen.h and made public,
4825 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4826 * (aopForSym): added an optimization to directly store in stack of
4827 the operand of a SEND iCode,
4828 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4829 but as registers instead (AOP_REG) using the fReturnIdx array,
4830 * (pic16_freeAsmop): remove the freed register from the
4831 _G.sregsAlloc field,
4832 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4833 a compare of 'WREG',
4834 * (pic16_popGetTempRegCond): changed function prototype, now
4835 function takes also a bitVector argument v which holds the current
4836 set of registers that are allocated for stack access by aopForSym,
4837 registers allocated in aopForSym for accessing stack symbols are not
4838 any more part of the functions usedRegs field,
4839 * (genCall): some times aopOp is called for a stack variable to be
4840 send, aopForSym might perform the push, if this is true make sure
4841 that genCall doesn't push the variable twice by testing _G.resDirect,
4842 * (genFunction): changed testing for unspecified interrupt number
4843 from 256 to INTNO_UNSPEC,
4844 * modified selection scheme of frame pointer generation. Previously
4845 if function did use local registers a frame pointer was generated,
4846 now a frame pointer is generated only if function has arguments
4847 (that need PLUSW2 register access), or has stack arguments, or the
4848 compiler is not instructed to omit the frame pointer,
4849 * (genEndFunction): before restoring local registers that were saved
4850 in the function preamble, also restore the registers that *might*
4851 have been allocated for stack access,
4852 * (genRet): removed some old comments,
4853 * (genCmp, the active (RN's) version): added a call to the
4854 pic16_genCmp_special function to perform the compare with a more
4855 robust and optimized way,
4856 * (genInline): a feature has been added in inline code generation,
4857 which allows a wildcard variable substitution when writing inline
4858 assembly. Code is incomplete and experimental therefore undocumented,
4859 * (genCast): changed order of aopOp for result and right to allow
4860 aopForSym to directly load the result if possible,
4861 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4862 perform an optimized compare on some selected special occasions,
4863 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4864 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4865 generate an IVT any more,
4866 * src/pic16/main.c (pic16_optionsTable): added command line option
4868 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4869 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4871 * src/pic16/NOTES: Raphael Neider added in list of active developers
4872 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4873 jumptable_end to prevent bug #,
4874 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4875 inCond and outCond fields,
4876 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4877 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4878 turn off register spilling,
4879 * (packRegsForOneUse): synced with other ports' versions although it
4880 is not used currently,
4881 * (pic16_packRegisters): added an optimization while reading
4882 structure bitfields, some registers may be saved (malloc code is
4883 decreased by 80 bytes)
4885 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4887 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4888 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4889 this can be optimized more?
4891 2005-03-10 Raphael Neider <rneider AT web.de>
4893 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4894 genNearPointerGet): (hopefully) fixed access to bitfields via
4895 pointers (p->bitN = x; and x = p->bitN; failed)
4897 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5084 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5085 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5086 this might fix SIGSEGVs on MinGW...
5087 * src/SDCCopt.c (killDeadCode): restored original behaviour
5088 (volatile operands might get thrown away though)
5090 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

8613 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8615 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8616 loaded with the linker search paths (-L arguments) and the libraries
8617 to be linked with the current source (-l arguments). Changes
8618 currently will affect only the pic16 port.
8619 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8620 include path the port specific paths and port specific libraries,
8621 * gplink command now contains the $3 argument,
8622 * src/pic16/device.h,
8623 * src/pic16/device.c,: structure PIC_device is made public and
8624 renamed to PIC16_device, the same for variable Pics which is renamed

8639 Documenting changes from previous commits.
8640 * configure.in (version 1.56),
8641 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8642 when generating output files to configure the pic16 library,
8643 but now I've commented it out, since gputils aren't installed in the
8644 SF compile farm, so library won't compile
8646 * device/lib/Makefile.in (version 1.56): initially I've added in
8647 target 'all' the prerequestive 'model-pic16' so it compiled the
8648 pic16 library, but now I've commented it out for the same reasons
8650 * added targets 'model-pic16' and 'objects-pic16' to compile the
8652 * added target 'port-specific-objects-pic16' to handle the
8653 generated libraries and copy them into the build/ directory
8654 * added target 'clean-intermediate-pic16' to clean intermediate
8655 files into pic16 directory
8656 * in target 'installdirs' added line to create directory pic16 in
8657 the installation path
8659 * device/include/Makefile.in (version 1.11): in target 'install'
8660 added lines to copy all header files to installation path,
8661 * in target 'installdirs' added line create directory for pic16
8662 headers in the installation path

8677 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8678 option so that it actually works. Made it specific to the z80, since
8679 the gbz80 doesn't have these kinds of I/O ports.
8681 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8707 via literal number. The symbol is placed in the corresponding
8708 position of the data ram
8709 * (pic16_dump_section): relocatable and absolute uninitialized
8710 data are now emitted in sorted order to reduce section naming,
8711 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8712 weren't marked as being in the access bank,
8714 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>

8749 all over. Telling LaTeX to be less strict with word spacing
8750 to better keep the right margin. Changed some notes about
8751 maintainance of the ports in section 3.2.1 - is it OK like this?
8753 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8793 * src/pic16/peeph.def: all peepholes with movff are commented out,
8794 because there is a problem in the pcode peep optimizer,
8795 * src/pic16/ralloc.c: the register allocator can now reuse local

8888 include information about variables allocated to the overlay
8891 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8893 * as/mcs51/lkmain.c: Help about -Y option

8905 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8907 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8908 (default behaviour).
8910 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8912 A python script to validate compiler diagnostic messages. It can be
8913 used to verify that sdcc complains about bad c source code and
8914 gives a good location of the error.
8915 * support/valdiag/Makefile,
8916 * support/valdiag/valdiag.py,
8917 * support/valdiag/tests/*
8919 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8933 around the header file.
8934 Bug reported from Jesus Calvino-Fraga
8936 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8938 * sdcc.spec: updated
8939 * device/include/Makefile.in: don't install CVS directories
8940 * device/lib/Makefile.in: added removal of CVS directories after install
8941 * doc/Makefile: fixed install, added local_icons
8942 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8943 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8944 * src/ds390/gen.c (genRightShift): fixed bug #870788
8945 * src/SDCCast.c (decorateType): fixed bug #870781
8947 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8949 PIC16 port related changes:
8950 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8951 added variable stackPos,
8953 * gen.c: genCall, assignResultValue: added support for
8954 pushing/retrieving function parameters to/from stack,
8955 genFunction,genEndFunction: setup stack frame for the
8957 genAddrOf: will be changed according to bug 863624
8959 * added files genutils.c and genutils.h which contain gen*
8960 debugged and optimised functions extracted from gen.c
8962 * glue.c: added variable 'externs' which holds extern symbols,
8963 pic16emitRegularMap: is modified to properly handle relocatable
8964 symbols under the new scheme,
8965 pic16createInterruptVect: is modified
8966 pic16printPublics: is modified to emit 'global' assembler directives,
8967 added pic16_printExterns to print extern symbols,
8968 pic16glue: initializes stack/frame pointer in the beginning of
8969 the assembly output. Temporary hack, will be corrected later,
8970 because gplink yet does not support stack and SDCC does not
8971 yet support a type of crt0.o object to create the final binary.
8973 * Removed many lines that contain 8051 legacy code.
8974 * The code is finally placed under a 'code' directive.
8975 * Added port specific options.
8977 * _process_pragma: simplified since now we do not need *special*
8978 include file to define SFR registers. But a separate header
8979 will be needed. This will be developed later.
8980 * _pic16_parseOptions: added, parses port specific options:
8981 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8982 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8983 --preplace-udata-with=
8985 * _pic16_setDefaultOptions: modified to initialize section names,
8986 but hack is temporarly out of order since it needs improvement.
8987 * _pic16_genAssemblerPreamble: configuration words are emitted by
8988 their address instead of their name. This part is incomplete and
8989 supports only the 18Fxx2 devices. Other devices will emit an error
8990 during assembly since they do not contain the same set of config
8992 * _pic16_genIVT: is modified,
8994 * pcode.c: added definitions for some hardware registers that are needed
8996 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8997 All PCI entries are updated. Now LFSR is supported.
8998 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8999 * added pic16_newpCodeOpLit2 to support instructions with
9000 two literal arguments
9001 * pic16_pCode2str: corrected code that emits assembler instructions
9002 with two literal operands and those that have an access bit modifier
9003 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9004 this fixes a bug which caused some labels to be lost, when an
9005 assembler directive was added, i.e. banksel,
9006 * pic16_FixRegisterBanking: improved logic that causes the insertion
9008 * InlineFunction: functions that are called once, are not any more
9009 inlined. This can be a port option in the future,
9011 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9013 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9014 hold the corresponding uninitialized symbols,
9015 * pic16_allocProcessorRegister: registers have explicit marked the
9017 * pic16_allocInternalRegister: registers are explicit marked as
9019 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9020 processing list, so bit registers were lost,
9023 * ralloc.h: added field 'accessBank' and original symbol operand
9024 in register definition,
9025 * removed the field isMapped from register definition,
9027 ** Several functions have been removed from various sources:
9028 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9029 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9030 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9031 pic16_assignRelocatableRegisters
9033 ** others have been introduced:
9034 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9035 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9037 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9039 * support/scripts/inc2h.pl: changed definition of BIT_AT
9040 to emit 'sbit at' instead of 'bit at'. This was a request.
9042 PIC16 port related preliminary changes:
9043 * gen.c: prefixed function popRegFromString with
9044 pic16_ and all references to it corrected
9045 * pcode.c: all pic16_pc_* hardware registers prefixed
9046 with underscore (_),
9047 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9048 * ralloc.c: newReg(): when register is REG_SFR then
9049 set address to rIdx,
9050 pic16_allocProcessorRegister(): marks register wasUsed=0
9051 pic16_writeUsedRegs(): added a call to assign processor
9052 registers via pic16_assignFixedRegisters
9054 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9056 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9057 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9058 variables in unused register banks. Also the SSEG is placed
9059 wherever there is enough space for it, and IDATA can be anywhere
9060 in internal RAM. For now compile using -Wl-Y[stack_size].
9061 The mem file is different for this option as well, since it
9062 makes no sense of talking about DSEG lenght.
9064 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9066 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9067 in certain cases, e.g. when ROM assignment, patch provided
9068 from Albert den Haan.
9070 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9240 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9242 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165

9313 it breaks with bitfields, extern declarations, and gcse analysis.
9314 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9315 could be assigned through a pointer, so don't complain.

10075 copied from genNearPointerSet()
10076 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
10077 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
10078 If they pop r0/r1 they must be called in the opposite order than aopOp().
10079 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
10080 (resp. --stack-auto), prepared for --xstack

10091 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
10093 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10094 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10095 type for bits was changed. It resulted in bit variables becoming
10096 global, which is not permitted in PIC 14 assembly output.
10098 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10100 * doc/sdccman.lyx: various additions and updates. Rearranged sections
10102 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10104 Z80 and MCS51 linkers complaint if a public symbol is defined

10113 A few small changes that speed up the peephole optimizer.
10117 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10119 Try to make the peephole optimizer smarter by maintaining
10120 an association between the assembly source code and the
10121 iCodes that originated them. Put this information to use
10122 with a new peephole rule condition "notVolatile" so that
10123 the rules can be aggressive yet still safe.
10128 * src/mcs51/peeph.def
10130 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10134 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10135 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10136 if the left or right operand symbols have the accuse flag set.
10138 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10140 Changed the type of the result of the ! (NOT) operator to char;
10141 previously it returned the same type as the source. This allows
10142 us to eliminate all the genFloatNot functions (all of its target
10143 implementations were very buggy) since !float can use the same
10146 * src/SDCCicode.c (ast2iCode): ! returns char

10155 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10156 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10157 during interrupts. Ensure WSAVE is located at a shared bank address.
10158 2. Fixed page selection in some places
10159 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10160 the registers name strings.
10161 4. Fixed "signed / unsigned compare" compiler warnings.
10162 5. The PIC port manages its own allocation of the general purpose
10163 registers, but makes no attempt to reuse them. As a result when
10164 compiling it soon runs out of general purpose registers. Some
10165 additional code was added to the files pcode.c and device.c to walk
10166 through the function call tree and rename the registers so that they
10176 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

10185 Made bitfield a distinct type from bit so that bitfields
10186 convert as per ANSI C and bits retain their traditional
10187 boolean style behaviour. Implemented bitfield support in
10195 * src/ds390/gen.c: bit v bitfield split
10196 * src/z80/gen.c: New support for bitfields
10197 * support/regression/tests/bitfields.c: reenabled z80,
10200 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

10211 for literal assignments in genPackBits (thanks to Frieder for
10217 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10219 Fixed bug #748310 (pointer to function type mishandled when the

10249 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10251 Made the constant following the "interrupt" keyword optional. If
10252 omitted, the function will not automatically be given an entry
10253 in the interrupt vector table (similar to #pragma NOIV, but
10254 less syntacticly kludgy). The interrupt number is also now
10255 range checked. Also fixed a bug in the high order bit example

10731 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10732 the regression tests I'm not brave enough to enable 245.b, 245.c
10733 * doc/sdccman.lyx: added latex preamble for hyperref package.
10734 Using pdflatex this will give you a hyperlinked pdf file with

10785 added if/endif conditional macros to remove options help
10786 messages from optionsTable when a port is not configured, added
10787 support for the PIc16 port in the ports table, when executing
10788 the compiler with no port specified on command line, a default
10789 port is selected with the new macro DEFAULT_PORT which is
10790 defined in port.h, in setDefaultOptions() linkOptions is removed
10791 from initialization assignment, since now it is a set,
10792 parseCmdLine uses setParseWithComma for linkOptions, in
10793 linkEdit() linkOptions are accessed with new function indexSet()
10794 which returns the i'th item of a set variable. See SDCCset.c, in
10795 linkEdit() when calling buildCmdLine(), added linkOptions as
10796 last argument. Now users can pass arguments to gplink via the
10797 -Wl option, main() uses pic16glue() to glue up pic16 programs

10809 * src/pic16/glue.c: commented out some error producing lines
10810 * src/pic16/main.c: __config directives are commented out to stop
10811 gpasm complaining and test the linkage with gplink, _linkCmd and
10812 _asmCmd changed to be more gplink and gpasm friendly
10813 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10814 produced an error when parsed, peep rule 12 is added to utilize
10815 movff, but it is commented out since the pCode does not support
10816 yet a command with 2 address arguments
10818 2003-05-18 <johan AT balder>
10820 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11881 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11883 * in /sdcc/as/mcs51/ changed these files in order to create an
11884 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11885 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11886 following files to include the previous two files: aslink.dsp,
11887 Makefile.aslink, Makefile.bcc, and Makefile.in.
11889 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11890 .adb instead of .cdb
11892 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11894 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11895 value from option --iram-size.
11897 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11899 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11902 2002-09-18 <wiml AT hhhh.org>
11904 * SDCClrange.h: exposed setFromRange() and setToRange()
11905 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11906 packRegsForAccUse() (bug 542397)
11907 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11908 multiple times and emitting the fetch operations more than once
11909 added aopGetUsesAcc() function to allow binary operators to
11910 fetch their operands in the correct order; made genMinus() emit
11911 compact code for X = LITERAL - Y
11913 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11914 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11915 sprintf() in line 1267.
11917 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11918 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11921 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11922 Changes to aslink (All the changes are marked with 'JCF'):
11924 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11927 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11928 area BSEG. Also moves, if possible, the DATA area down into the internal
11929 ram so more space is available.
11931 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11934 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11935 not bytes. Function summary() which creates a memory usage summary
11936 file with extension .mem. Reports of overlaping stack and small stack
11937 size. If the space for the stack is less than 16 bytes aslink trows a
11940 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11941 the 8051. Option 'y' for memory summary output file.
11943 Changes to sdcc (All the changes are marked with 'JCF'):
11945 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11947 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11948 overlaying area for it (uses RegBankUsed[4]).
11950 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11951 bank zero as used by default. By default aslink locates the stack
11952 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11953 the creation of the .mem file. Delegates the allocation of data area
11954 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11955 the begining of the stack area to aslink.
11957 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11958 glue() in SDCCglue.c creates an area for it.
11960 2002-09-03 Borut Razem <borut.razem AT siol.net>
11961 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11962 sdcc/src/pic/glue.c:
11963 introduced atexit() handler for teporay files removal in case of
11964 errors, assertions, ...
11966 2002-08-29 Borut Razem <borut.razem AT siol.net>
11967 * sdcc/support/cpp2/auto-host_vc_in.h:
11968 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11969 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11970 Maybe there is a similar problem with BORLANDC? It should be checked!
11972 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11973 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11974 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11975 was not executed, and the compiler (cl) launched a warning:
11976 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11978 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11979 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11981 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11982 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects

11990 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11991 - added Release configuration in VS projects
11992 - review of compiler an linker options
11993 - VC .exe files are generated in bin_vc directory, not to interfere
11994 with binaries generated from other projects (cygwin, mingw, bcc ...)
11996 * sdcc/src/yacc.dsp: added
11998 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11999 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12000 and insert the version number definitions from .version
12002 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp

12016 2002-08-10 Borut Razem <borut.razem AT siol.net>
12017 * src/SDCCmain.c (main):
12018 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12019 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12020 The consequence was that some temporary files were not removed.
12023 unification of code in functions tempfilename() and tempfile():
12024 function tempnam() is defined in Visual Studio 6.0 and .NET
12026 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12028 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12029 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

12031 - update a list of source files, included into the project
12033 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12034 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12035 changed project type to Generic Project so that can be correcly converted to VS.NET project
12037 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12039 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

12043 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12044 added return 0 statements after assert() to make compiler happy
12046 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12047 added newline in the def file to keep MSC compiler satisfied
12049 * sdcc/src/z80/gen.c:
12050 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12051 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12052 - solved MSC error in function aopDump()
12054 * sdcc_vc.h: define PREFIX as "\\sdcc"
12056 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

12229 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12231 * sdcc/src/SDCCloop.c:
12232 Previous fix was not good. basic blocks that have "break" or "return" are
12233 not really partof a loop , but live ranges used in these blocks should
12234 be live thru the entire loop, so set partOfLoop but don't add them to
