1915 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1917 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1918 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1920 One basic decision: e.g. src/clean.mk includes further files. In order
1921 to make this work there are two solutions:
1922 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1923 run configure on them. This way they can use
1924 'include $(srcdir)/port-clean.mk'
1925 - always include clean.mk by the Makefile at the same level. To avoid
1926 that `make clean` tries to include and build Makefile.dep the
1927 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1928 implemented, because now even `make uninstall` doesn't create
1929 Makefile.in. clean.mk could be eliminated by pasting it in
1932 * debugger/mcs51/Makefile.in: build own objects from library sources
1933 (SLIB, SDCC) in current directory
1935 * configure, configure.in: renamed --disable-device-lib-build in
1936 --disable-device-lib; added --enable-doc, the required tools are
1937 searched by configure; added result message; the toolchain for the
1938 belonging ports are now only built, if the port is enabled.
1940 * support/regression/*: all output is written in directory gen, because
1941 the fwk and ports directories don't livet in the build tree using vpath
1943 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1944 --disable-device-lib, added --enable-doc, added section VPATH
1946 * sim/ucsim/configure.in,
1947 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1948 z80 are enabled by default
1950 2006-04-24 Raphael Neider <rneider AT web.de>
1952 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1953 to config word, "pic14_"-prefixed some extern functions
1954 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1955 config word has been found
1956 * src/pic/device.h: added prototypes
1957 * src/pic/pcode.c: added "pic14_"-prefix where needed
1958 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1960 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1975 (pCodeRegOptimizeRegUsage): fixed typo in comment

1979 * device/examples/main8051.c: deleted - it was removed from CVS

2207 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
2209 * src/SDCCpeeph.c (operandsLiteral): new, added,

2220 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
2221 implemented patch 1120823 Thanks to Willy De la Court (normal
2222 interrupts need an interrupt number now if they are made critical),
2223 and enabled nesting of critical functions though not for gbz80
2224 (genCritical, genEndCritical): added functions
2225 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2226 * src/z80/mappings.i: added "ei" to all mappings
2228 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2230 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
2231 submitted by the Debian SDCC maintainer Aurelien Jarno:
2232 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
2233 archive with gcc 4.1 on mips and wrote the patch"
2235 2006-03-16 Raphael Neider <rneider AT web.de>
2237 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
2238 the left operand is shorter than the result (c* = lit-c* + int),
2240 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2243 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2245 * src/.version: increased version number to 2.5.5
2246 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2247 linking is done manually in pic16 port's _linkEdit,
2248 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2249 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2250 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2251 allocate asmop as AOP_ACC,
2252 (aopForRemat): added parameter 'bool result' in function declaration,
2253 (pic16_aopGet): return AOP_ACC when accessing WREG,
2254 (pic16_popGetTempReg): minor modification,
2255 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2256 'pic16_allocWithIdx',
2257 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
2258 calling function in absolute addresses,
2259 (genAssign): take into account AOP_ACC asmop,
2260 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
2261 * src/pic16/pcoderegs.c: some debug functions and lines added,
2262 * src/pic16/ralloc.c (decodeRegType): added but commented out,
2263 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2265 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2266 call to allocReg, not by manually allocating a new one,
2267 (pic16_assignRegisters): now before going through the register
2268 allocating functions mark all registers as free. This eliminates some
2269 side effects resulting from peephole parser done earlier in the backbone
2271 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
2273 * src/SDCCicode.c (geniCodeLogic),

2292 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
2293 (aopForSym, aopOp): increment asmop.allocated if reused,
2294 (freeAsmop): decrement asmop.allocated and check for zero instead of
2296 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2297 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
2298 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

2321 2006-03-06 Borut Razem <borut.razem AT siol.net>
2323 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2324 made the linker quiet
2326 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2328 * src/pic16/gen.c (genPcall): fixed bug #1443644
2329 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2330 which dumps before the function entry point a data byte which represents
2331 the number of the local variables used by the specified function, added
2332 'xinst' for initial support for Extended Instruction Support,
2333 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2334 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2335 port->fun_prefix anymore (may change later),
2336 (genFunction, genEndFunction): do not store/restore local registers for
2337 _main (this should take care the --main-return command line option in
2339 (genOr): removed some legacy pic-port instructions,
2340 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2341 performing operations with SFR's causes data to be written more than
2342 once to each SFR. Perhaps SFRs should be handled in special cases...
2343 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2345 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2346 into account for stack starting position,
2347 (struct OPTIONS pic16_optionsTable): added command line argument
2348 --extended or -y for Extended Instruction Support,
2349 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2350 (deassignLRs): *** perhaps the most important change, old 'for' code
2351 (commented out for reference), didn't account for some registers which
2352 were left marked 'not free' after a pointer operation. The change
2353 reduces register usage a lot in some cases
2355 2006-03-04 Borut Razem <borut.razem AT siol.net>

4717 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4718 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4720 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4722 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4723 prevent compiler warning
4725 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4727 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4728 moved to level 0 and declared as static. Also they are explicit
4729 placed in access bank. This was necessery because some times they
4730 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4731 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4732 optimizations. Currently only compare to unsigned char is implemented,
4733 * src/pic16/gen.c: added fReturnIdx array,
4734 * (struct resolvedIfx) is moved to gen.h and made public,
4735 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4736 * (aopForSym): added an optimization to directly store in stack of
4737 the operand of a SEND iCode,
4738 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4739 but as registers instead (AOP_REG) using the fReturnIdx array,
4740 * (pic16_freeAsmop): remove the freed register from the
4741 _G.sregsAlloc field,
4742 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4743 a compare of 'WREG',
4744 * (pic16_popGetTempRegCond): changed function prototype, now
4745 function takes also a bitVector argument v which holds the current
4746 set of registers that are allocated for stack access by aopForSym,
4747 registers allocated in aopForSym for accessing stack symbols are not
4748 any more part of the functions usedRegs field,
4749 * (genCall): some times aopOp is called for a stack variable to be
4750 send, aopForSym might perform the push, if this is true make sure
4751 that genCall doesn't push the variable twice by testing _G.resDirect,
4752 * (genFunction): changed testing for unspecified interrupt number
4753 from 256 to INTNO_UNSPEC,
4754 * modified selection scheme of frame pointer generation. Previously
4755 if function did use local registers a frame pointer was generated,
4756 now a frame pointer is generated only if function has arguments
4757 (that need PLUSW2 register access), or has stack arguments, or the
4758 compiler is not instructed to omit the frame pointer,
4759 * (genEndFunction): before restoring local registers that were saved
4760 in the function preamble, also restore the registers that *might*
4761 have been allocated for stack access,
4762 * (genRet): removed some old comments,
4763 * (genCmp, the active (RN's) version): added a call to the
4764 pic16_genCmp_special function to perform the compare with a more
4765 robust and optimized way,
4766 * (genInline): a feature has been added in inline code generation,
4767 which allows a wildcard variable substitution when writing inline
4768 assembly. Code is incomplete and experimental therefore undocumented,
4769 * (genCast): changed order of aopOp for result and right to allow
4770 aopForSym to directly load the result if possible,
4771 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4772 perform an optimized compare on some selected special occasions,
4773 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4774 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4775 generate an IVT any more,
4776 * src/pic16/main.c (pic16_optionsTable): added command line option
4778 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4779 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4781 * src/pic16/NOTES: Raphael Neider added in list of active developers
4782 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4783 jumptable_end to prevent bug #,
4784 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4785 inCond and outCond fields,
4786 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4787 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4788 turn off register spilling,
4789 * (packRegsForOneUse): synced with other ports' versions although it
4790 is not used currently,
4791 * (pic16_packRegisters): added an optimization while reading
4792 structure bitfields, some registers may be saved (malloc code is
4793 decreased by 80 bytes)
4795 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4797 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4798 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4799 this can be optimized more?
4801 2005-03-10 Raphael Neider <rneider AT web.de>
4803 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4804 genNearPointerGet): (hopefully) fixed access to bitfields via
4805 pointers (p->bitN = x; and x = p->bitN; failed)

5131 access stack and frame pointers. They are initially assigned to
5132 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
5133 accessing SFRs. Updated all occurences of modification of stack or
5134 frame pointer in gen.c and pcode.c,
5135 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
5136 assigning of a literal value to pointers,

5439 Adding support for replacing ljmps with sjmps in jumptables
5440 generated for switch statements. For now you need to set the
5441 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5442 Now 4 algorithms for mcs51 jumptable generation are used:
5443 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5444 addresses loaded pc-relative for up to 112 cases and stack-pushing
5445 target addresses loaded with offset from dptr for up to 256 cases.

5477 * added libc directory. The current version of LibC contains string
5478 functions, ctype functions and macros and some functions of the
5479 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5480 be extensively tested in the future. Standard disclaimer here.

5493 * (pic16_storeForReturn): optimized return of 0,
5494 * (genCmp): experimental code for new genCmp which uses PIC18's
5495 special compare&skip instructions. Initial tests fail some times
5496 with variables grater than 1 byte in size, so new code is disabled,
5497 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5499 * (genCast): began a fix to optimize the casting of a bit to another
5500 bit, now assigning a bitfield to another bitfield will fail, sorry,

5515 * src/pic16/ralloc.c (allocReg): add preliminary support for
5516 supporting a limited set of temporary registers,
5518 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8525 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8526 loaded with the linker search paths (-L arguments) and the libraries
8527 to be linked with the current source (-l arguments). Changes
8528 currently will affect only the pic16 port.
8529 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8530 include path the port specific paths and port specific libraries,
8531 * gplink command now contains the $3 argument,
8532 * src/pic16/device.h,
8533 * src/pic16/device.c,: structure PIC_device is made public and

8549 Documenting changes from previous commits.
8550 * configure.in (version 1.56),
8551 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8552 when generating output files to configure the pic16 library,
8553 but now I've commented it out, since gputils aren't installed in the
8554 SF compile farm, so library won't compile
8556 * device/lib/Makefile.in (version 1.56): initially I've added in
8557 target 'all' the prerequestive 'model-pic16' so it compiled the
8558 pic16 library, but now I've commented it out for the same reasons
8560 * added targets 'model-pic16' and 'objects-pic16' to compile the
8562 * added target 'port-specific-objects-pic16' to handle the
8563 generated libraries and copy them into the build/ directory
8564 * added target 'clean-intermediate-pic16' to clean intermediate
8565 files into pic16 directory
8566 * in target 'installdirs' added line to create directory pic16 in

8588 option so that it actually works. Made it specific to the z80, since
8589 the gbz80 doesn't have these kinds of I/O ports.
8591 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8593 * device/include/z180.h,

8617 via literal number. The symbol is placed in the corresponding
8618 position of the data ram
8619 * (pic16_dump_section): relocatable and absolute uninitialized
8620 data are now emitted in sorted order to reduce section naming,
8621 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8622 weren't marked as being in the access bank,

8700 UPPER for immediate operands,
8701 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8703 * src/pic16/peeph.def: all peepholes with movff are commented out,
8704 because there is a problem in the pcode peep optimizer,
8705 * src/pic16/ralloc.c: the register allocator can now reuse local
8706 function symbols for another function. This saves register usage.
8707 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8709 Added file src/pic16/NOTES with information about program writing on
8710 the current port version.

8798 include information about variables allocated to the overlay
8801 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8803 * as/mcs51/lkmain.c: Help about -Y option

8815 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8817 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8818 (default behaviour).
8820 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8822 A python script to validate compiler diagnostic messages. It can be
8823 used to verify that sdcc complains about bad c source code and
8824 gives a good location of the error.
8825 * support/valdiag/Makefile,
8826 * support/valdiag/valdiag.py,
8827 * support/valdiag/tests/*

8844 Bug reported from Jesus Calvino-Fraga
8846 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8848 * sdcc.spec: updated
8849 * device/include/Makefile.in: don't install CVS directories
8850 * device/lib/Makefile.in: added removal of CVS directories after install
8851 * doc/Makefile: fixed install, added local_icons
8852 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8853 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8854 * src/ds390/gen.c (genRightShift): fixed bug #870788
8855 * src/SDCCast.c (decorateType): fixed bug #870781
8857 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8859 PIC16 port related changes:
8860 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8861 added variable stackPos,
8863 * gen.c: genCall, assignResultValue: added support for
8864 pushing/retrieving function parameters to/from stack,
8865 genFunction,genEndFunction: setup stack frame for the
8867 genAddrOf: will be changed according to bug 863624
8869 * added files genutils.c and genutils.h which contain gen*
8870 debugged and optimised functions extracted from gen.c
8872 * glue.c: added variable 'externs' which holds extern symbols,
8873 pic16emitRegularMap: is modified to properly handle relocatable
8874 symbols under the new scheme,
8875 pic16createInterruptVect: is modified
8876 pic16printPublics: is modified to emit 'global' assembler directives,
8877 added pic16_printExterns to print extern symbols,
8878 pic16glue: initializes stack/frame pointer in the beginning of
8879 the assembly output. Temporary hack, will be corrected later,
8880 because gplink yet does not support stack and SDCC does not
8881 yet support a type of crt0.o object to create the final binary.
8883 * Removed many lines that contain 8051 legacy code.
8884 * The code is finally placed under a 'code' directive.
8885 * Added port specific options.
8887 * _process_pragma: simplified since now we do not need *special*
8888 include file to define SFR registers. But a separate header
8889 will be needed. This will be developed later.
8890 * _pic16_parseOptions: added, parses port specific options:
8891 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8892 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8893 --preplace-udata-with=
8895 * _pic16_setDefaultOptions: modified to initialize section names,
8896 but hack is temporarly out of order since it needs improvement.
8897 * _pic16_genAssemblerPreamble: configuration words are emitted by
8898 their address instead of their name. This part is incomplete and
8899 supports only the 18Fxx2 devices. Other devices will emit an error
8900 during assembly since they do not contain the same set of config
8902 * _pic16_genIVT: is modified,
8904 * pcode.c: added definitions for some hardware registers that are needed
8906 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8907 All PCI entries are updated. Now LFSR is supported.
8908 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8909 * added pic16_newpCodeOpLit2 to support instructions with
8910 two literal arguments
8911 * pic16_pCode2str: corrected code that emits assembler instructions
8912 with two literal operands and those that have an access bit modifier
8913 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8914 this fixes a bug which caused some labels to be lost, when an
8915 assembler directive was added, i.e. banksel,
8916 * pic16_FixRegisterBanking: improved logic that causes the insertion
8918 * InlineFunction: functions that are called once, are not any more
8919 inlined. This can be a port option in the future,
8921 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8923 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8924 hold the corresponding uninitialized symbols,
8925 * pic16_allocProcessorRegister: registers have explicit marked the
8927 * pic16_allocInternalRegister: registers are explicit marked as
8929 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8930 processing list, so bit registers were lost,
8933 * ralloc.h: added field 'accessBank' and original symbol operand
8934 in register definition,
8935 * removed the field isMapped from register definition,
8937 ** Several functions have been removed from various sources:
8938 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8939 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8940 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8941 pic16_assignRelocatableRegisters
8943 ** others have been introduced:
8944 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8945 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8947 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8949 * support/scripts/inc2h.pl: changed definition of BIT_AT
8950 to emit 'sbit at' instead of 'bit at'. This was a request.
8952 PIC16 port related preliminary changes:
8953 * gen.c: prefixed function popRegFromString with
8954 pic16_ and all references to it corrected
8955 * pcode.c: all pic16_pc_* hardware registers prefixed
8956 with underscore (_),
8957 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8958 * ralloc.c: newReg(): when register is REG_SFR then
8959 set address to rIdx,
8960 pic16_allocProcessorRegister(): marks register wasUsed=0
8961 pic16_writeUsedRegs(): added a call to assign processor
8962 registers via pic16_assignFixedRegisters
8964 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8966 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8967 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8968 variables in unused register banks. Also the SSEG is placed
8969 wherever there is enough space for it, and IDATA can be anywhere
8970 in internal RAM. For now compile using -Wl-Y[stack_size].
8971 The mem file is different for this option as well, since it
8972 makes no sense of talking about DSEG lenght.
8974 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8976 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8977 in certain cases, e.g. when ROM assignment, patch provided
8978 from Albert den Haan.
8980 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9886 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9888 Fixed bug #621531 (const & volatile confusion in the type chain).
9889 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

9985 copied from genNearPointerSet()
9986 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9987 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9988 If they pop r0/r1 they must be called in the opposite order than aopOp().
9989 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9990 (resp. --stack-auto), prepared for --xstack

10003 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10004 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
10005 type for bits was changed. It resulted in bit variables becoming
10006 global, which is not permitted in PIC 14 assembly output.
10008 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

10023 A few small changes that speed up the peephole optimizer.
10027 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10029 Try to make the peephole optimizer smarter by maintaining
10030 an association between the assembly source code and the
10031 iCodes that originated them. Put this information to use
10032 with a new peephole rule condition "notVolatile" so that
10033 the rules can be aggressive yet still safe.
10038 * src/mcs51/peeph.def
10040 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10044 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10045 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10046 if the left or right operand symbols have the accuse flag set.
10048 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10050 Changed the type of the result of the ! (NOT) operator to char;
10051 previously it returned the same type as the source. This allows
10052 us to eliminate all the genFloatNot functions (all of its target
10053 implementations were very buggy) since !float can use the same

10065 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10066 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10067 during interrupts. Ensure WSAVE is located at a shared bank address.
10068 2. Fixed page selection in some places
10069 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10070 the registers name strings.
10071 4. Fixed "signed / unsigned compare" compiler warnings.
10072 5. The PIC port manages its own allocation of the general purpose
10073 registers, but makes no attempt to reuse them. As a result when
10074 compiling it soon runs out of general purpose registers. Some
10075 additional code was added to the files pcode.c and device.c to walk
10076 through the function call tree and rename the registers so that they
10086 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10087 genPlus() & genMinus() when the result is the same as left or right

10093 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10095 Made bitfield a distinct type from bit so that bitfields
10096 convert as per ANSI C and bits retain their traditional
10097 boolean style behaviour. Implemented bitfield support in
10105 * src/ds390/gen.c: bit v bitfield split
10106 * src/z80/gen.c: New support for bitfields
10107 * support/regression/tests/bitfields.c: reenabled z80,
10110 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10112 Rules 246.x, 247.x relate to bitfields, the others speed up
10113 access to xdata mapped I/O devices.
10115 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10117 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10119 Cleaned up genPackBits and genUnpackBits and added two helper
10120 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10121 for literal assignments in genPackBits (thanks to Frieder for
10127 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10129 Fixed bug #748310 (pointer to function type mishandled when the
10130 function name is omitted). Also fixed a SIGSEGV when a function
10131 attribute (reentrant, etc) is used on a non-function or on a
10132 function but misplaced before the parameter list.
10134 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10136 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10137 * support/Util/SDCCerr.h,

10159 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10161 Made the constant following the "interrupt" keyword optional. If
10162 omitted, the function will not automatically be given an entry
10163 in the interrupt vector table (similar to #pragma NOIV, but
10164 less syntacticly kludgy). The interrupt number is also now
10165 range checked. Also fixed a bug in the high order bit example

10181 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10183 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10184 be re-activated by defining REDUCE_LITERALS)
10185 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10186 unsigned, but are signed by default

10697 support for the PIc16 port in the ports table, when executing
10698 the compiler with no port specified on command line, a default
10699 port is selected with the new macro DEFAULT_PORT which is
10700 defined in port.h, in setDefaultOptions() linkOptions is removed
10701 from initialization assignment, since now it is a set,

11765 * src/SDCCicode.c: fixed array add
11767 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11768 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests

11775 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11776 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
11778 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11779 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
11780 * support/regression/tests/bug-524697.c: fit mem usage into 8032
11782 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11783 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11785 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11786 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11788 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11789 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11791 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11793 * in /sdcc/as/mcs51/ changed these files in order to create an
11794 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11795 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11796 following files to include the previous two files: aslink.dsp,
11797 Makefile.aslink, Makefile.bcc, and Makefile.in.
11799 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11800 .adb instead of .cdb
11802 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11804 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11805 value from option --iram-size.
11807 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11809 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11812 2002-09-18 <wiml AT hhhh.org>
11814 * SDCClrange.h: exposed setFromRange() and setToRange()
11815 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11816 packRegsForAccUse() (bug 542397)
11817 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11818 multiple times and emitting the fetch operations more than once
11819 added aopGetUsesAcc() function to allow binary operators to
11820 fetch their operands in the correct order; made genMinus() emit
11821 compact code for X = LITERAL - Y
11823 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11824 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11825 sprintf() in line 1267.
11827 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11828 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11831 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11832 Changes to aslink (All the changes are marked with 'JCF'):
11834 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11837 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11838 area BSEG. Also moves, if possible, the DATA area down into the internal
11839 ram so more space is available.
11841 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11844 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11845 not bytes. Function summary() which creates a memory usage summary
11846 file with extension .mem. Reports of overlaping stack and small stack
11847 size. If the space for the stack is less than 16 bytes aslink trows a
11850 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11851 the 8051. Option 'y' for memory summary output file.
11853 Changes to sdcc (All the changes are marked with 'JCF'):
11855 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11857 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11858 overlaying area for it (uses RegBankUsed[4]).
11860 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11861 bank zero as used by default. By default aslink locates the stack
11862 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11863 the creation of the .mem file. Delegates the allocation of data area
11864 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11865 the begining of the stack area to aslink.
11867 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11868 glue() in SDCCglue.c creates an area for it.
11870 2002-09-03 Borut Razem <borut.razem AT siol.net>
11871 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11872 sdcc/src/pic/glue.c:
11873 introduced atexit() handler for teporay files removal in case of
11874 errors, assertions, ...
11876 2002-08-29 Borut Razem <borut.razem AT siol.net>
11877 * sdcc/support/cpp2/auto-host_vc_in.h:
11878 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11879 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11880 Maybe there is a similar problem with BORLANDC? It should be checked!
11882 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11883 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11884 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11885 was not executed, and the compiler (cl) launched a warning:
11886 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11888 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11889 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11891 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11892 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11894 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11895 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11896 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11897 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11898 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11899 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11900 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11901 - added Release configuration in VS projects
11902 - review of compiler an linker options
11903 - VC .exe files are generated in bin_vc directory, not to interfere
11904 with binaries generated from other projects (cygwin, mingw, bcc ...)
11906 * sdcc/src/yacc.dsp: added
11908 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11909 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11910 and insert the version number definitions from .version
11912 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11914 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11915 added - genarate auto-host.h using auto-host_vc_in.h as template
11918 removed from CVS, generated automatically
11920 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11921 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11923 2002-08-11 Borut Razem <borut.razem AT siol.net>
11924 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11926 2002-08-10 Borut Razem <borut.razem AT siol.net>
11927 * src/SDCCmain.c (main):
11928 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11929 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11930 The consequence was that some temporary files were not removed.
11933 unification of code in functions tempfilename() and tempfile():
11934 function tempnam() is defined in Visual Studio 6.0 and .NET
11936 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11938 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11939 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11940 - removed compiler command line option /WX: Treats all warnings as errors
11941 - update a list of source files, included into the project
11943 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11944 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11945 changed project type to Generic Project so that can be correcly converted to VS.NET project
11947 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11949 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11951 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11953 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11954 added return 0 statements after assert() to make compiler happy
11956 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11957 added newline in the def file to keep MSC compiler satisfied
11959 * sdcc/src/z80/gen.c:
11960 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11961 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11962 - solved MSC error in function aopDump()
11964 * sdcc_vc.h: define PREFIX as "\\sdcc"
11966 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11967 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11969 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11970 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11971 - Rewrote the register banking algorithm.
