2023 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
2025 Enabled VPATH feature: changed nearly all Makefiles (149 files).
2026 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
2028 One basic decision: e.g. src/clean.mk includes further files. In order
2029 to make this work there are two solutions:
2030 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
2031 run configure on them. This way they can use
2032 'include $(srcdir)/port-clean.mk'
2033 - always include clean.mk by the Makefile at the same level. To avoid
2034 that `make clean` tries to include and build Makefile.dep the
2035 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
2036 implemented, because now even `make uninstall` doesn't create
2037 Makefile.in. clean.mk could be eliminated by pasting it in
2040 * debugger/mcs51/Makefile.in: build own objects from library sources
2041 (SLIB, SDCC) in current directory
2043 * configure, configure.in: renamed --disable-device-lib-build in
2044 --disable-device-lib; added --enable-doc, the required tools are
2045 searched by configure; added result message; the toolchain for the
2046 belonging ports are now only built, if the port is enabled.
2048 * support/regression/*: all output is written in directory gen, because
2049 the fwk and ports directories don't livet in the build tree using vpath
2051 * doc/sdccman.lyx: renamed --disable-device-lib-build to
2052 --disable-device-lib, added --enable-doc, added section VPATH
2054 * sim/ucsim/configure.in,
2055 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
2056 z80 are enabled by default
2058 2006-04-24 Raphael Neider <rneider AT web.de>
2060 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
2061 to config word, "pic14_"-prefixed some extern functions
2062 (pic14_emitConfigWord): emit __config directive(s) if assignment to
2063 config word has been found
2064 * src/pic/device.h: added prototypes
2065 * src/pic/pcode.c: added "pic14_"-prefix where needed

2068 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2071 (pic14createInterruptVect): moved generating __config directives away

2329 implemented patch 1120823 Thanks to Willy De la Court (normal
2330 interrupts need an interrupt number now if they are made critical),
2331 and enabled nesting of critical functions though not for gbz80
2332 (genCritical, genEndCritical): added functions
2333 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2334 * src/z80/mappings.i: added "ei" to all mappings

2346 the left operand is shorter than the result (c* = lit-c* + int),
2348 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2351 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2353 * src/.version: increased version number to 2.5.5
2354 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2355 linking is done manually in pic16 port's _linkEdit,
2356 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2357 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2358 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2359 allocate asmop as AOP_ACC,
2360 (aopForRemat): added parameter 'bool result' in function declaration,
2361 (pic16_aopGet): return AOP_ACC when accessing WREG,
2362 (pic16_popGetTempReg): minor modification,

2373 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2374 call to allocReg, not by manually allocating a new one,
2375 (pic16_assignRegisters): now before going through the register
2376 allocating functions mark all registers as free. This eliminates some
2377 side effects resulting from peephole parser done earlier in the backbone
2379 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2437 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2438 which dumps before the function entry point a data byte which represents
2439 the number of the local variables used by the specified function, added
2440 'xinst' for initial support for Extended Instruction Support,
2441 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2442 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2443 port->fun_prefix anymore (may change later),
2444 (genFunction, genEndFunction): do not store/restore local registers for
2445 _main (this should take care the --main-return command line option in
2447 (genOr): removed some legacy pic-port instructions,
2448 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2449 performing operations with SFR's causes data to be written more than
2450 once to each SFR. Perhaps SFRs should be handled in special cases...
2451 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2453 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2454 into account for stack starting position,

2456 --extended or -y for Extended Instruction Support,
2457 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2458 (deassignLRs): *** perhaps the most important change, old 'for' code
2459 (commented out for reference), didn't account for some registers which
2460 were left marked 'not free' after a pointer operation. The change
2461 reduces register usage a lot in some cases

4712 where not placed in the same memory bank,
4713 * device/lib/pic16/libsdcc/char/: various modifications to improve
4714 library performance,

4725 if condition == CARRY)
4726 * (genCmp): adapted to new genSkipc semantics
4727 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
4728 on rIfx (genCmp was broken)
4730 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4732 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
4733 * src/z80/main.c (_keywords[]),
4734 * src/SDCCglobal.h (struct options),
4736 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4737 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4738 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4739 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4740 always available in leading double underscore form. The C99 support is
4741 mostly missing, but it's a start.
4742 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4743 reserved identifier "__data".
4745 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
4747 * src/mcs51/peeph.def: fixed bug 1170013
4749 2005-03-22 Maarten Brock <sourceforge.brock AT dse.nl>

4755 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
4758 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4760 * src/port.h (struct PORT),

4789 immedDom() returning wrong block; probably fixes bug #1160833)
4791 2005-03-20 Borut Razem <borut.razem AT siol.net>
4793 * support/scripts/inc2h.pl: WIN32 port
4795 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4797 * device/lib/makefile.in: added abs.c and labs.c
4799 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4801 * device/include/stdint.h: added
4802 * device/lib/abs.c: added
4803 * device/lib/labs.c: added
4804 * device/include/stdlib.h: added abs() and labs() prototypes

4821 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4823 * device/lib/printf_large.c: removed inline assembly for portability and
4824 readability. Use printf_fast if speed or size are more important.
4825 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4826 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4828 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4830 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4831 prevent compiler warning
4833 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4835 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4836 moved to level 0 and declared as static. Also they are explicit
4837 placed in access bank. This was necessery because some times they
4838 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4839 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4840 optimizations. Currently only compare to unsigned char is implemented,
4841 * src/pic16/gen.c: added fReturnIdx array,
4842 * (struct resolvedIfx) is moved to gen.h and made public,
4843 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4844 * (aopForSym): added an optimization to directly store in stack of
4845 the operand of a SEND iCode,
4846 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4847 but as registers instead (AOP_REG) using the fReturnIdx array,
4848 * (pic16_freeAsmop): remove the freed register from the
4849 _G.sregsAlloc field,
4850 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4851 a compare of 'WREG',
4852 * (pic16_popGetTempRegCond): changed function prototype, now
4853 function takes also a bitVector argument v which holds the current
4854 set of registers that are allocated for stack access by aopForSym,
4855 registers allocated in aopForSym for accessing stack symbols are not
4856 any more part of the functions usedRegs field,
4857 * (genCall): some times aopOp is called for a stack variable to be
4858 send, aopForSym might perform the push, if this is true make sure
4859 that genCall doesn't push the variable twice by testing _G.resDirect,
4860 * (genFunction): changed testing for unspecified interrupt number
4861 from 256 to INTNO_UNSPEC,
4862 * modified selection scheme of frame pointer generation. Previously
4863 if function did use local registers a frame pointer was generated,
4864 now a frame pointer is generated only if function has arguments
4865 (that need PLUSW2 register access), or has stack arguments, or the
4866 compiler is not instructed to omit the frame pointer,
4867 * (genEndFunction): before restoring local registers that were saved
4868 in the function preamble, also restore the registers that *might*
4869 have been allocated for stack access,
4870 * (genRet): removed some old comments,
4871 * (genCmp, the active (RN's) version): added a call to the
4872 pic16_genCmp_special function to perform the compare with a more
4873 robust and optimized way,
4874 * (genInline): a feature has been added in inline code generation,
4875 which allows a wildcard variable substitution when writing inline
4876 assembly. Code is incomplete and experimental therefore undocumented,
4877 * (genCast): changed order of aopOp for result and right to allow
4878 aopForSym to directly load the result if possible,
4879 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4880 perform an optimized compare on some selected special occasions,
4881 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4882 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4883 generate an IVT any more,
4884 * src/pic16/main.c (pic16_optionsTable): added command line option
4886 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4887 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4889 * src/pic16/NOTES: Raphael Neider added in list of active developers
4890 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4891 jumptable_end to prevent bug #,
4892 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4893 inCond and outCond fields,
4894 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4895 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4896 turn off register spilling,
4897 * (packRegsForOneUse): synced with other ports' versions although it
4898 is not used currently,
4899 * (pic16_packRegisters): added an optimization while reading
4900 structure bitfields, some registers may be saved (malloc code is
4901 decreased by 80 bytes)
4903 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4905 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4906 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4907 this can be optimized more?
4909 2005-03-10 Raphael Neider <rneider AT web.de>
4911 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4912 genNearPointerGet): (hopefully) fixed access to bitfields via
4913 pointers (p->bitN = x; and x = p->bitN; failed)
4915 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

5102 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
5103 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5104 this might fix SIGSEGVs on MinGW...
5105 * src/SDCCopt.c (killDeadCode): restored original behaviour
5106 (volatile operands might get thrown away though)
5108 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

5147 when calling assembler to reflect memory model used, also define
5148 macro STACK_MODEL_{SMALL/LARGE} when compiling and assembling to
5149 reflect stack model used,

5585 * added libc directory. The current version of LibC contains string
5586 functions, ctype functions and macros and some functions of the
5587 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5588 be extensively tested in the future. Standard disclaimer here.
5589 Library is not automatically build yet. But one can build it by
5590 invoking 'make' inside the libc directory.
5591 * added ADC library under libio. Preliminary version yet.
5593 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

5601 * (pic16_storeForReturn): optimized return of 0,
5602 * (genCmp): experimental code for new genCmp which uses PIC18's
5603 special compare&skip instructions. Initial tests fail some times
5604 with variables grater than 1 byte in size, so new code is disabled,
5605 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5607 * (genCast): began a fix to optimize the casting of a bit to another
5608 bit, now assigning a bitfield to another bitfield will fail, sorry,
5609 * src/pic16/main.c: disabled the use of lr-support feature,
5610 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5613 bits with offset (case PO_GPR_BIT),
5614 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5616 * (isBankInstruction): modified to return 0 for no banking instruction,
5617 and 1 for banking instruction,
5618 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5619 caused stop processing pCodes after a inline assembly block,
5620 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5621 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5622 registers when it shouldn't,
5623 * src/pic16/ralloc.c (allocReg): add preliminary support for
5624 supporting a limited set of temporary registers,
5626 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5632 (genFunction): optimize RECEIVE iCodes in reentrant functions
5634 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8631 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8633 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8634 loaded with the linker search paths (-L arguments) and the libraries
8635 to be linked with the current source (-l arguments). Changes
8636 currently will affect only the pic16 port.
8637 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8638 include path the port specific paths and port specific libraries,
8639 * gplink command now contains the $3 argument,
8640 * src/pic16/device.h,
8641 * src/pic16/device.c,: structure PIC_device is made public and
8642 renamed to PIC16_device, the same for variable Pics which is renamed

8657 Documenting changes from previous commits.
8658 * configure.in (version 1.56),
8659 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8660 when generating output files to configure the pic16 library,
8661 but now I've commented it out, since gputils aren't installed in the
8662 SF compile farm, so library won't compile
8664 * device/lib/Makefile.in (version 1.56): initially I've added in
8665 target 'all' the prerequestive 'model-pic16' so it compiled the
8666 pic16 library, but now I've commented it out for the same reasons
8668 * added targets 'model-pic16' and 'objects-pic16' to compile the
8670 * added target 'port-specific-objects-pic16' to handle the
8671 generated libraries and copy them into the build/ directory
8672 * added target 'clean-intermediate-pic16' to clean intermediate
8673 files into pic16 directory
8674 * in target 'installdirs' added line to create directory pic16 in
8675 the installation path
8677 * device/include/Makefile.in (version 1.11): in target 'install'
8678 added lines to copy all header files to installation path,

8728 data are now emitted in sorted order to reduce section naming,
8729 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8730 weren't marked as being in the access bank,
8732 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8734 Added portion of GNU PIC Library under the directory
8735 device/include/pic16 and device/lib/pic16. These files
8736 contain the declarations of SFRs for the PIC18Fxx2 devices.

8767 all over. Telling LaTeX to be less strict with word spacing
8768 to better keep the right margin. Changed some notes about
8769 maintainance of the ports in section 3.2.1 - is it OK like this?
8771 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8811 * src/pic16/peeph.def: all peepholes with movff are commented out,
8812 because there is a problem in the pcode peep optimizer,
8813 * src/pic16/ralloc.c: the register allocator can now reuse local

8906 include information about variables allocated to the overlay
8909 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8911 * as/mcs51/lkmain.c: Help about -Y option

8923 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8925 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8926 (default behaviour).
8928 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8930 A python script to validate compiler diagnostic messages. It can be
8931 used to verify that sdcc complains about bad c source code and
8932 gives a good location of the error.
8933 * support/valdiag/Makefile,
8934 * support/valdiag/valdiag.py,
8935 * support/valdiag/tests/*
8937 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8950 * src/common.h: added ifndef/define/endif macros
8951 around the header file.
8952 Bug reported from Jesus Calvino-Fraga
8954 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8956 * sdcc.spec: updated
8957 * device/include/Makefile.in: don't install CVS directories
8958 * device/lib/Makefile.in: added removal of CVS directories after install
8959 * doc/Makefile: fixed install, added local_icons
8960 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8961 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8962 * src/ds390/gen.c (genRightShift): fixed bug #870788
8963 * src/SDCCast.c (decorateType): fixed bug #870781
8965 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8967 PIC16 port related changes:
8968 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8969 added variable stackPos,
8971 * gen.c: genCall, assignResultValue: added support for
8972 pushing/retrieving function parameters to/from stack,
8973 genFunction,genEndFunction: setup stack frame for the
8975 genAddrOf: will be changed according to bug 863624
8977 * added files genutils.c and genutils.h which contain gen*
8978 debugged and optimised functions extracted from gen.c
8980 * glue.c: added variable 'externs' which holds extern symbols,
8981 pic16emitRegularMap: is modified to properly handle relocatable
8982 symbols under the new scheme,
8983 pic16createInterruptVect: is modified
8984 pic16printPublics: is modified to emit 'global' assembler directives,
8985 added pic16_printExterns to print extern symbols,
8986 pic16glue: initializes stack/frame pointer in the beginning of
8987 the assembly output. Temporary hack, will be corrected later,
8988 because gplink yet does not support stack and SDCC does not
8989 yet support a type of crt0.o object to create the final binary.
8991 * Removed many lines that contain 8051 legacy code.
8992 * The code is finally placed under a 'code' directive.
8993 * Added port specific options.
8995 * _process_pragma: simplified since now we do not need *special*
8996 include file to define SFR registers. But a separate header
8997 will be needed. This will be developed later.
8998 * _pic16_parseOptions: added, parses port specific options:
8999 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
9000 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
9001 --preplace-udata-with=
9003 * _pic16_setDefaultOptions: modified to initialize section names,
9004 but hack is temporarly out of order since it needs improvement.
9005 * _pic16_genAssemblerPreamble: configuration words are emitted by
9006 their address instead of their name. This part is incomplete and
9007 supports only the 18Fxx2 devices. Other devices will emit an error
9008 during assembly since they do not contain the same set of config
9010 * _pic16_genIVT: is modified,
9012 * pcode.c: added definitions for some hardware registers that are needed
9014 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
9015 All PCI entries are updated. Now LFSR is supported.
9016 * Removed pic16_pciTRIS is mentioned by mdubuc in source
9017 * added pic16_newpCodeOpLit2 to support instructions with
9018 two literal arguments
9019 * pic16_pCode2str: corrected code that emits assembler instructions
9020 with two literal operands and those that have an access bit modifier
9021 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
9022 this fixes a bug which caused some labels to be lost, when an
9023 assembler directive was added, i.e. banksel,
9024 * pic16_FixRegisterBanking: improved logic that causes the insertion
9026 * InlineFunction: functions that are called once, are not any more
9027 inlined. This can be a port option in the future,
9029 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
9031 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
9032 hold the corresponding uninitialized symbols,
9033 * pic16_allocProcessorRegister: registers have explicit marked the
9035 * pic16_allocInternalRegister: registers are explicit marked as
9037 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
9038 processing list, so bit registers were lost,
9041 * ralloc.h: added field 'accessBank' and original symbol operand
9042 in register definition,
9043 * removed the field isMapped from register definition,
9045 ** Several functions have been removed from various sources:
9046 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
9047 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
9048 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
9049 pic16_assignRelocatableRegisters
9051 ** others have been introduced:
9052 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
9053 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
9055 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
9057 * support/scripts/inc2h.pl: changed definition of BIT_AT
9058 to emit 'sbit at' instead of 'bit at'. This was a request.
9060 PIC16 port related preliminary changes:
9061 * gen.c: prefixed function popRegFromString with
9062 pic16_ and all references to it corrected
9063 * pcode.c: all pic16_pc_* hardware registers prefixed
9064 with underscore (_),
9065 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
9066 * ralloc.c: newReg(): when register is REG_SFR then
9067 set address to rIdx,
9068 pic16_allocProcessorRegister(): marks register wasUsed=0
9069 pic16_writeUsedRegs(): added a call to assign processor
9070 registers via pic16_assignFixedRegisters
9072 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9074 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9075 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9076 variables in unused register banks. Also the SSEG is placed
9077 wherever there is enough space for it, and IDATA can be anywhere
9078 in internal RAM. For now compile using -Wl-Y[stack_size].
9079 The mem file is different for this option as well, since it
9080 makes no sense of talking about DSEG lenght.
9082 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9084 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9085 in certain cases, e.g. when ROM assignment, patch provided
9086 from Albert den Haan.
9088 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10111 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10112 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10113 type for bits was changed. It resulted in bit variables becoming
10114 global, which is not permitted in PIC 14 assembly output.
10116 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10118 * doc/sdccman.lyx: various additions and updates. Rearranged sections

10129 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10131 A few small changes that speed up the peephole optimizer.
10135 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10137 Try to make the peephole optimizer smarter by maintaining
10138 an association between the assembly source code and the
10139 iCodes that originated them. Put this information to use
10140 with a new peephole rule condition "notVolatile" so that
10141 the rules can be aggressive yet still safe.
10146 * src/mcs51/peeph.def
10148 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10152 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10153 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10154 if the left or right operand symbols have the accuse flag set.
10156 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10158 Changed the type of the result of the ! (NOT) operator to char;
10159 previously it returned the same type as the source. This allows
10160 us to eliminate all the genFloatNot functions (all of its target
10161 implementations were very buggy) since !float can use the same
10164 * src/SDCCicode.c (ast2iCode): ! returns char

10171 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
10173 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10174 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10175 during interrupts. Ensure WSAVE is located at a shared bank address.
10176 2. Fixed page selection in some places
10177 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10178 the registers name strings.
10179 4. Fixed "signed / unsigned compare" compiler warnings.
10180 5. The PIC port manages its own allocation of the general purpose
10181 registers, but makes no attempt to reuse them. As a result when
10182 compiling it soon runs out of general purpose registers. Some
10183 additional code was added to the files pcode.c and device.c to walk
10184 through the function call tree and rename the registers so that they
10194 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10195 genPlus() & genMinus() when the result is the same as left or right

10201 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10203 Made bitfield a distinct type from bit so that bitfields
10204 convert as per ANSI C and bits retain their traditional
10205 boolean style behaviour. Implemented bitfield support in
10213 * src/ds390/gen.c: bit v bitfield split
10214 * src/z80/gen.c: New support for bitfields
10215 * support/regression/tests/bitfields.c: reenabled z80,
10218 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10220 Rules 246.x, 247.x relate to bitfields, the others speed up
10221 access to xdata mapped I/O devices.
10223 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10225 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10227 Cleaned up genPackBits and genUnpackBits and added two helper
10228 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10229 for literal assignments in genPackBits (thanks to Frieder for
10235 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10237 Fixed bug #748310 (pointer to function type mishandled when the
10238 function name is omitted). Also fixed a SIGSEGV when a function
10239 attribute (reentrant, etc) is used on a non-function or on a
10240 function but misplaced before the parameter list.
10242 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed

10267 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10269 Made the constant following the "interrupt" keyword optional. If
10270 omitted, the function will not automatically be given an entry
10271 in the interrupt vector table (similar to #pragma NOIV, but
10272 less syntacticly kludgy). The interrupt number is also now
10273 range checked. Also fixed a bug in the high order bit example

10718 * doc/sdccman.lyx: Changes all over, index improved, smaller margins. The manual
10719 is in parts still quite out of date, I did changes as far as I felt makes sense
10720 for a non-native english speaker.
10721 Please feel free to add to the manual or to correct my changes.
10722 * doc/Makefile: undid touching the date of intermediate tex files.
10724 2003-05-26 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

10743 src/pic/pic.dsp, src/pic16/pic16.dsp, src/xa51/xa51.dsp,
10744 src/x80/z80.dsp: peep.rul is bigger now, so /Zm1000 is used

10749 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10750 the regression tests I'm not brave enough to enable 245.b, 245.c
10751 * doc/sdccman.lyx: added latex preamble for hyperref package.
10752 Using pdflatex this will give you a hyperlinked pdf file with
10753 bookmarks. (prepend '%' before /usepackage if this breaks something)
10755 2003-05-24 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

10802 * src/SDCCmain.c: linkOptions is changed to set *,
10803 added if/endif conditional macros to remove options help
10804 messages from optionsTable when a port is not configured, added
10805 support for the PIc16 port in the ports table, when executing
10806 the compiler with no port specified on command line, a default
10807 port is selected with the new macro DEFAULT_PORT which is
10808 defined in port.h, in setDefaultOptions() linkOptions is removed
10809 from initialization assignment, since now it is a set,
10810 parseCmdLine uses setParseWithComma for linkOptions, in
10811 linkEdit() linkOptions are accessed with new function indexSet()
10812 which returns the i'th item of a set variable. See SDCCset.c, in
10813 linkEdit() when calling buildCmdLine(), added linkOptions as
10814 last argument. Now users can pass arguments to gplink via the
10815 -Wl option, main() uses pic16glue() to glue up pic16 programs
10816 * src/SDCCpeeph.c: various changes to support pic16
10817 * src/SDCCset.c: added function void *indexSet(set *, int) to

10827 * src/pic16/glue.c: commented out some error producing lines
10828 * src/pic16/main.c: __config directives are commented out to stop
10829 gpasm complaining and test the linkage with gplink, _linkCmd and
10830 _asmCmd changed to be more gplink and gpasm friendly
10831 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10832 produced an error when parsed, peep rule 12 is added to utilize
10833 movff, but it is commented out since the pCode does not support
10834 yet a command with 2 address arguments
10836 2003-05-18 <johan AT balder>
10838 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11902 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11903 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11904 following files to include the previous two files: aslink.dsp,
11905 Makefile.aslink, Makefile.bcc, and Makefile.in.
11907 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11908 .adb instead of .cdb
11910 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11912 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11913 value from option --iram-size.
11915 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11917 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11920 2002-09-18 <wiml AT hhhh.org>
11922 * SDCClrange.h: exposed setFromRange() and setToRange()
11923 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11924 packRegsForAccUse() (bug 542397)
11925 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11926 multiple times and emitting the fetch operations more than once
11927 added aopGetUsesAcc() function to allow binary operators to
11928 fetch their operands in the correct order; made genMinus() emit
11929 compact code for X = LITERAL - Y
11931 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11932 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11933 sprintf() in line 1267.
11935 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11936 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11939 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11940 Changes to aslink (All the changes are marked with 'JCF'):
11942 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11945 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11946 area BSEG. Also moves, if possible, the DATA area down into the internal
11947 ram so more space is available.
11949 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11952 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11953 not bytes. Function summary() which creates a memory usage summary
11954 file with extension .mem. Reports of overlaping stack and small stack
11955 size. If the space for the stack is less than 16 bytes aslink trows a
11958 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11959 the 8051. Option 'y' for memory summary output file.
11961 Changes to sdcc (All the changes are marked with 'JCF'):
11963 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11965 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11966 overlaying area for it (uses RegBankUsed[4]).
11968 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11969 bank zero as used by default. By default aslink locates the stack
11970 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11971 the creation of the .mem file. Delegates the allocation of data area
11972 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11973 the begining of the stack area to aslink.
11975 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11976 glue() in SDCCglue.c creates an area for it.
11978 2002-09-03 Borut Razem <borut.razem AT siol.net>
11979 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11980 sdcc/src/pic/glue.c:
11981 introduced atexit() handler for teporay files removal in case of
11982 errors, assertions, ...
11984 2002-08-29 Borut Razem <borut.razem AT siol.net>
11985 * sdcc/support/cpp2/auto-host_vc_in.h:
11986 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11987 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11988 Maybe there is a similar problem with BORLANDC? It should be checked!
11990 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11991 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11992 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11993 was not executed, and the compiler (cl) launched a warning:
11994 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11996 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>

12003 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
12004 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
12005 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12006 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
12007 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
12008 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
12009 - added Release configuration in VS projects
12010 - review of compiler an linker options
12011 - VC .exe files are generated in bin_vc directory, not to interfere
12012 with binaries generated from other projects (cygwin, mingw, bcc ...)
12014 * sdcc/src/yacc.dsp: added
12016 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
12017 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
12018 and insert the version number definitions from .version
12020 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
12022 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

12029 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
12031 2002-08-11 Borut Razem <borut.razem AT siol.net>
12032 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
12034 2002-08-10 Borut Razem <borut.razem AT siol.net>
12035 * src/SDCCmain.c (main):
12036 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
12037 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
12038 The consequence was that some temporary files were not removed.
12041 unification of code in functions tempfilename() and tempfile():
12042 function tempnam() is defined in Visual Studio 6.0 and .NET
12044 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
12046 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
12047 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

12049 - update a list of source files, included into the project
12051 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
12052 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
12053 changed project type to Generic Project so that can be correcly converted to VS.NET project
12055 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
12057 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
12059 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
12061 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
12062 added return 0 statements after assert() to make compiler happy
12064 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
12065 added newline in the def file to keep MSC compiler satisfied
12067 * sdcc/src/z80/gen.c:
12068 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
12069 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
12070 - solved MSC error in function aopDump()
12072 * sdcc_vc.h: define PREFIX as "\\sdcc"
12074 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

12247 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
12249 * sdcc/src/SDCCloop.c:
12250 Previous fix was not good. basic blocks that have "break" or "return" are
12251 not really partof a loop , but live ranges used in these blocks should
12252 be live thru the entire loop, so set partOfLoop but don't add them to
12255 2002-02-21 <johan AT FRIJA>
12257 * src/SDCCcse.c: fixed bug #514308
12259 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
