22 a sharebank, use a non-shared bank for the stack if none available
23 * src/pic/device.h (struct memRange): added linked list next field,
24 added prototypes for above functions

30 (FixRegisterBanking): added optimization for devices with only one
31 possibly aliased bank of memory, like 16f84
32 * src/pic/glue.c (pic14_constructAbsMap): back to udata_ovr, as some

1950 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1952 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1953 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1955 One basic decision: e.g. src/clean.mk includes further files. In order
1956 to make this work there are two solutions:
1957 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1958 run configure on them. This way they can use
1959 'include $(srcdir)/port-clean.mk'
1960 - always include clean.mk by the Makefile at the same level. To avoid
1961 that `make clean` tries to include and build Makefile.dep the
1962 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1963 implemented, because now even `make uninstall` doesn't create
1964 Makefile.in. clean.mk could be eliminated by pasting it in
1967 * debugger/mcs51/Makefile.in: build own objects from library sources
1968 (SLIB, SDCC) in current directory
1970 * configure, configure.in: renamed --disable-device-lib-build in
1971 --disable-device-lib; added --enable-doc, the required tools are
1972 searched by configure; added result message; the toolchain for the
1973 belonging ports are now only built, if the port is enabled.
1975 * support/regression/*: all output is written in directory gen, because
1976 the fwk and ports directories don't livet in the build tree using vpath
1978 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1979 --disable-device-lib, added --enable-doc, added section VPATH
1981 * sim/ucsim/configure.in,
1982 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1983 z80 are enabled by default
1985 2006-04-24 Raphael Neider <rneider AT web.de>
1987 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1988 to config word, "pic14_"-prefixed some extern functions
1989 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1990 config word has been found
1991 * src/pic/device.h: added prototypes
1992 * src/pic/pcode.c: added "pic14_"-prefix where needed
1993 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1995 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

2010 (pCodeRegOptimizeRegUsage): fixed typo in comment

2233 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
2235 * src/mcs51/gen.c (genCall): fixed bug 1457608
2237 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

2242 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
2244 * src/SDCCpeeph.c (operandsLiteral): new, added,

2256 implemented patch 1120823 Thanks to Willy De la Court (normal
2257 interrupts need an interrupt number now if they are made critical),
2258 and enabled nesting of critical functions though not for gbz80
2259 (genCritical, genEndCritical): added functions
2260 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2261 * src/z80/mappings.i: added "ei" to all mappings

2270 2006-03-16 Raphael Neider <rneider AT web.de>
2272 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
2273 the left operand is shorter than the result (c* = lit-c* + int),
2275 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2278 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2280 * src/.version: increased version number to 2.5.5
2281 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2282 linking is done manually in pic16 port's _linkEdit,
2283 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2284 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2285 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2286 allocate asmop as AOP_ACC,
2287 (aopForRemat): added parameter 'bool result' in function declaration,
2288 (pic16_aopGet): return AOP_ACC when accessing WREG,
2289 (pic16_popGetTempReg): minor modification,
2290 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2291 'pic16_allocWithIdx',

2298 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2300 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2301 call to allocReg, not by manually allocating a new one,
2302 (pic16_assignRegisters): now before going through the register
2303 allocating functions mark all registers as free. This eliminates some
2304 side effects resulting from peephole parser done earlier in the backbone
2306 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
2308 * src/SDCCicode.c (geniCodeLogic),

2327 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
2328 (aopForSym, aopOp): increment asmop.allocated if reused,
2329 (freeAsmop): decrement asmop.allocated and check for zero instead of
2331 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2332 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
2333 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

2364 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2365 which dumps before the function entry point a data byte which represents
2366 the number of the local variables used by the specified function, added
2367 'xinst' for initial support for Extended Instruction Support,
2368 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2369 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2370 port->fun_prefix anymore (may change later),
2371 (genFunction, genEndFunction): do not store/restore local registers for
2372 _main (this should take care the --main-return command line option in
2374 (genOr): removed some legacy pic-port instructions,
2375 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2376 performing operations with SFR's causes data to be written more than
2377 once to each SFR. Perhaps SFRs should be handled in special cases...
2378 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2380 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2381 into account for stack starting position,

2383 --extended or -y for Extended Instruction Support,
2384 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2385 (deassignLRs): *** perhaps the most important change, old 'for' code
2386 (commented out for reference), didn't account for some registers which
2387 were left marked 'not free' after a pointer operation. The change
2388 reduces register usage a lot in some cases
2390 2006-03-04 Borut Razem <borut.razem AT siol.net>

4707 * src/SDCCdflow.c (computeDataFlow),
4709 * src/SDCCloop.c (addDefInExprs, loopInvariants, loopOptimizations),
4711 * src/SDCCcflow.c (*),
4713 * src/SDCCBBlock.c (iCodeBreakDown, dumpEbbsToFileExt, eBBWithEntryLabel),
4714 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
4715 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
4716 immedDom() returning wrong block; probably fixes bug #1160833)
4718 2005-03-20 Borut Razem <borut.razem AT siol.net>
4720 * support/scripts/inc2h.pl: WIN32 port
4722 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
4724 * device/lib/makefile.in: added abs.c and labs.c
4726 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
4728 * device/include/stdint.h: added
4729 * device/lib/abs.c: added
4730 * device/lib/labs.c: added
4731 * device/include/stdlib.h: added abs() and labs() prototypes
4732 * device/lib/libsdcc.lib: added abs and labs
4733 * device/include/float.h,
4734 * device/lib/_fsmul.c,
4735 * device/lib/printf_fast.c,
4736 * device/lib/printf_tiny.c: updated comments
4738 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4740 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4743 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4745 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4746 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4748 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4750 * device/lib/printf_large.c: removed inline assembly for portability and
4751 readability. Use printf_fast if speed or size are more important.
4752 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4753 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4755 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4757 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4758 prevent compiler warning
4760 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4762 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4763 moved to level 0 and declared as static. Also they are explicit
4764 placed in access bank. This was necessery because some times they
4765 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4766 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4767 optimizations. Currently only compare to unsigned char is implemented,
4768 * src/pic16/gen.c: added fReturnIdx array,
4769 * (struct resolvedIfx) is moved to gen.h and made public,
4770 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4771 * (aopForSym): added an optimization to directly store in stack of
4772 the operand of a SEND iCode,
4773 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4774 but as registers instead (AOP_REG) using the fReturnIdx array,
4775 * (pic16_freeAsmop): remove the freed register from the
4776 _G.sregsAlloc field,
4777 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4778 a compare of 'WREG',
4779 * (pic16_popGetTempRegCond): changed function prototype, now
4780 function takes also a bitVector argument v which holds the current
4781 set of registers that are allocated for stack access by aopForSym,
4782 registers allocated in aopForSym for accessing stack symbols are not
4783 any more part of the functions usedRegs field,
4784 * (genCall): some times aopOp is called for a stack variable to be
4785 send, aopForSym might perform the push, if this is true make sure
4786 that genCall doesn't push the variable twice by testing _G.resDirect,
4787 * (genFunction): changed testing for unspecified interrupt number
4788 from 256 to INTNO_UNSPEC,
4789 * modified selection scheme of frame pointer generation. Previously
4790 if function did use local registers a frame pointer was generated,
4791 now a frame pointer is generated only if function has arguments
4792 (that need PLUSW2 register access), or has stack arguments, or the
4793 compiler is not instructed to omit the frame pointer,
4794 * (genEndFunction): before restoring local registers that were saved
4795 in the function preamble, also restore the registers that *might*
4796 have been allocated for stack access,
4797 * (genRet): removed some old comments,
4798 * (genCmp, the active (RN's) version): added a call to the
4799 pic16_genCmp_special function to perform the compare with a more
4800 robust and optimized way,
4801 * (genInline): a feature has been added in inline code generation,
4802 which allows a wildcard variable substitution when writing inline
4803 assembly. Code is incomplete and experimental therefore undocumented,
4804 * (genCast): changed order of aopOp for result and right to allow
4805 aopForSym to directly load the result if possible,
4806 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4807 perform an optimized compare on some selected special occasions,
4808 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4809 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4810 generate an IVT any more,
4811 * src/pic16/main.c (pic16_optionsTable): added command line option
4813 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4814 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4816 * src/pic16/NOTES: Raphael Neider added in list of active developers
4817 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4818 jumptable_end to prevent bug #,
4819 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4820 inCond and outCond fields,
4821 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4822 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4823 turn off register spilling,
4824 * (packRegsForOneUse): synced with other ports' versions although it
4825 is not used currently,
4826 * (pic16_packRegisters): added an optimization while reading
4827 structure bitfields, some registers may be saved (malloc code is
4828 decreased by 80 bytes)
4830 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4832 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4833 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4834 this can be optimized more?
4836 2005-03-10 Raphael Neider <rneider AT web.de>
4838 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4839 genNearPointerGet): (hopefully) fixed access to bitfields via
4840 pointers (p->bitN = x; and x = p->bitN; failed)
4842 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4885 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4886 to keep the correct label reference count when adding/removing references
4887 to labels. A peephole file using this is appended to patch #1144962.

5030 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
5031 this might fix SIGSEGVs on MinGW...

5123 copy the third byte from the int -- now assumes 0x80 (data memory)
5124 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
5125 operands (genAddLit expects the iCode's operands to swapped as

5475 generated for switch statements. For now you need to set the
5476 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5477 Now 4 algorithms for mcs51 jumptable generation are used:
5478 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

5510 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5512 * added libc directory. The current version of LibC contains string
5513 functions, ctype functions and macros and some functions of the
5514 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5515 be extensively tested in the future. Standard disclaimer here.
5516 Library is not automatically build yet. But one can build it by

5528 * (pic16_storeForReturn): optimized return of 0,
5529 * (genCmp): experimental code for new genCmp which uses PIC18's
5530 special compare&skip instructions. Initial tests fail some times
5531 with variables grater than 1 byte in size, so new code is disabled,
5532 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5534 * (genCast): began a fix to optimize the casting of a bit to another
5535 bit, now assigning a bitfield to another bitfield will fail, sorry,

5544 and 1 for banking instruction,
5545 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5546 caused stop processing pCodes after a inline assembly block,
5547 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5549 registers when it shouldn't,
5550 * src/pic16/ralloc.c (allocReg): add preliminary support for
5551 supporting a limited set of temporary registers,
5553 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5559 (genFunction): optimize RECEIVE iCodes in reentrant functions
5561 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5563 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5572 * device/lib/_gptrget.c (_gptrget),
5573 * device/lib/_gptrgetc.c (_gptrgetc),

8558 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8560 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8561 loaded with the linker search paths (-L arguments) and the libraries
8562 to be linked with the current source (-l arguments). Changes
8563 currently will affect only the pic16 port.
8564 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8565 include path the port specific paths and port specific libraries,
8566 * gplink command now contains the $3 argument,
8567 * src/pic16/device.h,
8568 * src/pic16/device.c,: structure PIC_device is made public and
8569 renamed to PIC16_device, the same for variable Pics which is renamed

8584 Documenting changes from previous commits.
8585 * configure.in (version 1.56),
8586 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8587 when generating output files to configure the pic16 library,
8588 but now I've commented it out, since gputils aren't installed in the
8589 SF compile farm, so library won't compile
8591 * device/lib/Makefile.in (version 1.56): initially I've added in
8592 target 'all' the prerequestive 'model-pic16' so it compiled the
8593 pic16 library, but now I've commented it out for the same reasons
8595 * added targets 'model-pic16' and 'objects-pic16' to compile the
8597 * added target 'port-specific-objects-pic16' to handle the
8598 generated libraries and copy them into the build/ directory
8599 * added target 'clean-intermediate-pic16' to clean intermediate
8600 files into pic16 directory
8601 * in target 'installdirs' added line to create directory pic16 in
8602 the installation path

8605 added lines to copy all header files to installation path,
8606 * in target 'installdirs' added line create directory for pic16
8607 headers in the installation path

8623 option so that it actually works. Made it specific to the z80, since
8624 the gbz80 doesn't have these kinds of I/O ports.
8626 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8628 * device/include/z180.h,

8652 via literal number. The symbol is placed in the corresponding
8653 position of the data ram
8654 * (pic16_dump_section): relocatable and absolute uninitialized
8655 data are now emitted in sorted order to reduce section naming,
8656 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8657 weren't marked as being in the access bank,
8659 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8661 Added portion of GNU PIC Library under the directory
8662 device/include/pic16 and device/lib/pic16. These files
8663 contain the declarations of SFRs for the PIC18Fxx2 devices.
8664 The directory is initialized via configure from toplevel.

8693 * doc/sdccman.lyx: Moved and added some sections, small changes
8694 all over. Telling LaTeX to be less strict with word spacing
8695 to better keep the right margin. Changed some notes about
8696 maintainance of the ports in section 3.2.1 - is it OK like this?
8698 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8736 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8738 * src/pic16/peeph.def: all peepholes with movff are commented out,
8739 because there is a problem in the pcode peep optimizer,
8740 * src/pic16/ralloc.c: the register allocator can now reuse local

8850 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8852 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8853 (default behaviour).
8855 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8857 A python script to validate compiler diagnostic messages. It can be
8858 used to verify that sdcc complains about bad c source code and
8859 gives a good location of the error.
8860 * support/valdiag/Makefile,
8861 * support/valdiag/valdiag.py,
8862 * support/valdiag/tests/*

8878 around the header file.
8879 Bug reported from Jesus Calvino-Fraga
8881 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8883 * sdcc.spec: updated
8884 * device/include/Makefile.in: don't install CVS directories
8885 * device/lib/Makefile.in: added removal of CVS directories after install
8886 * doc/Makefile: fixed install, added local_icons
8887 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8888 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8889 * src/ds390/gen.c (genRightShift): fixed bug #870788
8890 * src/SDCCast.c (decorateType): fixed bug #870781
8892 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8894 PIC16 port related changes:
8895 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8896 added variable stackPos,
8898 * gen.c: genCall, assignResultValue: added support for
8899 pushing/retrieving function parameters to/from stack,
8900 genFunction,genEndFunction: setup stack frame for the
8902 genAddrOf: will be changed according to bug 863624
8904 * added files genutils.c and genutils.h which contain gen*
8905 debugged and optimised functions extracted from gen.c
8907 * glue.c: added variable 'externs' which holds extern symbols,
8908 pic16emitRegularMap: is modified to properly handle relocatable
8909 symbols under the new scheme,
8910 pic16createInterruptVect: is modified
8911 pic16printPublics: is modified to emit 'global' assembler directives,
8912 added pic16_printExterns to print extern symbols,
8913 pic16glue: initializes stack/frame pointer in the beginning of
8914 the assembly output. Temporary hack, will be corrected later,
8915 because gplink yet does not support stack and SDCC does not
8916 yet support a type of crt0.o object to create the final binary.
8918 * Removed many lines that contain 8051 legacy code.
8919 * The code is finally placed under a 'code' directive.
8920 * Added port specific options.
8922 * _process_pragma: simplified since now we do not need *special*
8923 include file to define SFR registers. But a separate header
8924 will be needed. This will be developed later.
8925 * _pic16_parseOptions: added, parses port specific options:
8926 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8927 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8928 --preplace-udata-with=
8930 * _pic16_setDefaultOptions: modified to initialize section names,
8931 but hack is temporarly out of order since it needs improvement.
8932 * _pic16_genAssemblerPreamble: configuration words are emitted by
8933 their address instead of their name. This part is incomplete and
8934 supports only the 18Fxx2 devices. Other devices will emit an error
8935 during assembly since they do not contain the same set of config
8937 * _pic16_genIVT: is modified,
8939 * pcode.c: added definitions for some hardware registers that are needed
8941 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8942 All PCI entries are updated. Now LFSR is supported.
8943 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8944 * added pic16_newpCodeOpLit2 to support instructions with
8945 two literal arguments
8946 * pic16_pCode2str: corrected code that emits assembler instructions
8947 with two literal operands and those that have an access bit modifier
8948 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8949 this fixes a bug which caused some labels to be lost, when an
8950 assembler directive was added, i.e. banksel,
8951 * pic16_FixRegisterBanking: improved logic that causes the insertion
8953 * InlineFunction: functions that are called once, are not any more
8954 inlined. This can be a port option in the future,
8956 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8958 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8959 hold the corresponding uninitialized symbols,
8960 * pic16_allocProcessorRegister: registers have explicit marked the
8962 * pic16_allocInternalRegister: registers are explicit marked as
8964 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8965 processing list, so bit registers were lost,
8968 * ralloc.h: added field 'accessBank' and original symbol operand
8969 in register definition,
8970 * removed the field isMapped from register definition,
8972 ** Several functions have been removed from various sources:
8973 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8974 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8975 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8976 pic16_assignRelocatableRegisters
8978 ** others have been introduced:
8979 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8980 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8982 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8984 * support/scripts/inc2h.pl: changed definition of BIT_AT
8985 to emit 'sbit at' instead of 'bit at'. This was a request.
8987 PIC16 port related preliminary changes:
8988 * gen.c: prefixed function popRegFromString with
8989 pic16_ and all references to it corrected
8990 * pcode.c: all pic16_pc_* hardware registers prefixed
8991 with underscore (_),
8992 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8993 * ralloc.c: newReg(): when register is REG_SFR then
8994 set address to rIdx,
8995 pic16_allocProcessorRegister(): marks register wasUsed=0
8996 pic16_writeUsedRegs(): added a call to assign processor
8997 registers via pic16_assignFixedRegisters
8999 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9001 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
9002 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
9003 variables in unused register banks. Also the SSEG is placed
9004 wherever there is enough space for it, and IDATA can be anywhere
9005 in internal RAM. For now compile using -Wl-Y[stack_size].
9006 The mem file is different for this option as well, since it
9007 makes no sense of talking about DSEG lenght.
9009 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
9011 * src/SDCClrange.c: fixed bug 869095 that caused segfault
9012 in certain cases, e.g. when ROM assignment, patch provided
9013 from Albert den Haan.
9015 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9158 * src/mcs51/peephole.def,
9159 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

9921 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9923 Fixed bug #621531 (const & volatile confusion in the type chain).
9924 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

10038 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10039 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10040 type for bits was changed. It resulted in bit variables becoming
10041 global, which is not permitted in PIC 14 assembly output.
10043 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10045 * doc/sdccman.lyx: various additions and updates. Rearranged sections

10058 A few small changes that speed up the peephole optimizer.
10062 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10064 Try to make the peephole optimizer smarter by maintaining
10065 an association between the assembly source code and the
10066 iCodes that originated them. Put this information to use
10067 with a new peephole rule condition "notVolatile" so that
10068 the rules can be aggressive yet still safe.
10073 * src/mcs51/peeph.def
10075 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10079 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10080 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10081 if the left or right operand symbols have the accuse flag set.
10083 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10085 Changed the type of the result of the ! (NOT) operator to char;
10086 previously it returned the same type as the source. This allows
10087 us to eliminate all the genFloatNot functions (all of its target
10088 implementations were very buggy) since !float can use the same
10091 * src/SDCCicode.c (ast2iCode): ! returns char

10100 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10101 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10102 during interrupts. Ensure WSAVE is located at a shared bank address.
10103 2. Fixed page selection in some places
10104 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10105 the registers name strings.
10106 4. Fixed "signed / unsigned compare" compiler warnings.
10107 5. The PIC port manages its own allocation of the general purpose
10108 registers, but makes no attempt to reuse them. As a result when
10109 compiling it soon runs out of general purpose registers. Some
10110 additional code was added to the files pcode.c and device.c to walk
10111 through the function call tree and rename the registers so that they
10121 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10122 genPlus() & genMinus() when the result is the same as left or right

10128 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10130 Made bitfield a distinct type from bit so that bitfields
10131 convert as per ANSI C and bits retain their traditional
10132 boolean style behaviour. Implemented bitfield support in
10140 * src/ds390/gen.c: bit v bitfield split
10141 * src/z80/gen.c: New support for bitfields
10142 * support/regression/tests/bitfields.c: reenabled z80,
10145 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10147 Rules 246.x, 247.x relate to bitfields, the others speed up
10148 access to xdata mapped I/O devices.
10150 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10152 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10154 Cleaned up genPackBits and genUnpackBits and added two helper

10164 Fixed bug #748310 (pointer to function type mishandled when the
10165 function name is omitted). Also fixed a SIGSEGV when a function
10166 attribute (reentrant, etc) is used on a non-function or on a
10167 function but misplaced before the parameter list.
10169 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed

10196 Made the constant following the "interrupt" keyword optional. If
10197 omitted, the function will not automatically be given an entry
10198 in the interrupt vector table (similar to #pragma NOIV, but
10199 less syntacticly kludgy). The interrupt number is also now
10200 range checked. Also fixed a bug in the high order bit example

10221 unsigned, but are signed by default
10222 * src/SDCCval.c (constVal): rearranged
10223 * src/SDCCval.c (valMod): preliminary fix

10720 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
10721 it can be defined with CFLAGS when running configure
10722 * src/SDCCmain.c: fixed compiling + linking with object files
10724 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
10726 * configure.in: configure for pic16 port,
10727 added --disable-pic16-port
10728 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
10729 * src/SDCCmain.c: linkOptions is changed to set *,
10730 added if/endif conditional macros to remove options help
10731 messages from optionsTable when a port is not configured, added
10732 support for the PIc16 port in the ports table, when executing
10733 the compiler with no port specified on command line, a default
10734 port is selected with the new macro DEFAULT_PORT which is
10735 defined in port.h, in setDefaultOptions() linkOptions is removed
10736 from initialization assignment, since now it is a set,
10737 parseCmdLine uses setParseWithComma for linkOptions, in
10738 linkEdit() linkOptions are accessed with new function indexSet()
10739 which returns the i'th item of a set variable. See SDCCset.c, in
10740 linkEdit() when calling buildCmdLine(), added linkOptions as
10741 last argument. Now users can pass arguments to gplink via the
10742 -Wl option, main() uses pic16glue() to glue up pic16 programs
10743 * src/SDCCpeeph.c: various changes to support pic16
10744 * src/SDCCset.c: added function void *indexSet(set *, int) to
10745 return the i'th item of the set
10746 * src/SDCCset.h: added function prototype for indexSet()
10747 * src/SDCCsymt.c: in checkSClass(), added support for PIC16
10748 * src/clean.mk: added pic16 in CLEANALLPORTS variable

10750 added macro DEFAULT_PORT
10751 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
10752 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
10754 * src/pic16/glue.c: commented out some error producing lines
10755 * src/pic16/main.c: __config directives are commented out to stop
10756 gpasm complaining and test the linkage with gplink, _linkCmd and
10757 _asmCmd changed to be more gplink and gpasm friendly
10758 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10759 produced an error when parsed, peep rule 12 is added to utilize
10760 movff, but it is commented out since the pCode does not support
10761 yet a command with 2 address arguments
10763 2003-05-18 <johan AT balder>
10765 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10792 2003-05-11 Borut Razem <borut.razem AT siol.net>
10794 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
10795 the path of bin directory, so that PATH is the only env. variable, which has to be set
10796 in case of standard installation.

11813 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11814 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11821 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11823 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11824 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11826 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11828 * in /sdcc/as/mcs51/ changed these files in order to create an
11829 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11830 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11831 following files to include the previous two files: aslink.dsp,
11832 Makefile.aslink, Makefile.bcc, and Makefile.in.
11834 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11835 .adb instead of .cdb
11837 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11839 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11840 value from option --iram-size.
11842 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11844 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11847 2002-09-18 <wiml AT hhhh.org>
11849 * SDCClrange.h: exposed setFromRange() and setToRange()
11850 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11851 packRegsForAccUse() (bug 542397)
11852 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11853 multiple times and emitting the fetch operations more than once
11854 added aopGetUsesAcc() function to allow binary operators to
11855 fetch their operands in the correct order; made genMinus() emit
11856 compact code for X = LITERAL - Y
11858 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11859 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11860 sprintf() in line 1267.
11862 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11863 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11866 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11867 Changes to aslink (All the changes are marked with 'JCF'):
11869 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11872 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11873 area BSEG. Also moves, if possible, the DATA area down into the internal
11874 ram so more space is available.
11876 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11879 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11880 not bytes. Function summary() which creates a memory usage summary
11881 file with extension .mem. Reports of overlaping stack and small stack
11882 size. If the space for the stack is less than 16 bytes aslink trows a
11885 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11886 the 8051. Option 'y' for memory summary output file.
11888 Changes to sdcc (All the changes are marked with 'JCF'):
11890 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11892 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11893 overlaying area for it (uses RegBankUsed[4]).
11895 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11896 bank zero as used by default. By default aslink locates the stack
11897 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11898 the creation of the .mem file. Delegates the allocation of data area
11899 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11900 the begining of the stack area to aslink.
11902 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11903 glue() in SDCCglue.c creates an area for it.
11905 2002-09-03 Borut Razem <borut.razem AT siol.net>
11906 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11907 sdcc/src/pic/glue.c:
11908 introduced atexit() handler for teporay files removal in case of
11909 errors, assertions, ...
11911 2002-08-29 Borut Razem <borut.razem AT siol.net>
11912 * sdcc/support/cpp2/auto-host_vc_in.h:
11913 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11914 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11915 Maybe there is a similar problem with BORLANDC? It should be checked!
11917 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11918 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11919 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11920 was not executed, and the compiler (cl) launched a warning:
11921 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11923 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11924 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11926 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11927 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11929 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11930 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11931 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11932 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11933 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11934 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11935 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11936 - added Release configuration in VS projects
11937 - review of compiler an linker options
11938 - VC .exe files are generated in bin_vc directory, not to interfere
11939 with binaries generated from other projects (cygwin, mingw, bcc ...)
11941 * sdcc/src/yacc.dsp: added
11943 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11944 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11945 and insert the version number definitions from .version
11947 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11949 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11950 added - genarate auto-host.h using auto-host_vc_in.h as template
11953 removed from CVS, generated automatically
11955 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11956 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11958 2002-08-11 Borut Razem <borut.razem AT siol.net>
11959 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11961 2002-08-10 Borut Razem <borut.razem AT siol.net>
11962 * src/SDCCmain.c (main):
11963 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11964 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11965 The consequence was that some temporary files were not removed.
11968 unification of code in functions tempfilename() and tempfile():
11969 function tempnam() is defined in Visual Studio 6.0 and .NET

12177 Previous fix was not good. basic blocks that have "break" or "return" are
12178 not really partof a loop , but live ranges used in these blocks should

13057 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
13059 2001-08-29 Michael Hope <michaelh AT juju.net.nz>
