1897 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1898 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1900 One basic decision: e.g. src/clean.mk includes further files. In order
1901 to make this work there are two solutions:
1902 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1903 run configure on them. This way they can use
1904 'include $(srcdir)/port-clean.mk'
1905 - always include clean.mk by the Makefile at the same level. To avoid
1906 that `make clean` tries to include and build Makefile.dep the
1907 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1908 implemented, because now even `make uninstall` doesn't create
1909 Makefile.in. clean.mk could be eliminated by pasting it in
1912 * debugger/mcs51/Makefile.in: build own objects from library sources
1913 (SLIB, SDCC) in current directory
1915 * configure, configure.in: renamed --disable-device-lib-build in
1916 --disable-device-lib; added --enable-doc, the required tools are
1917 searched by configure; added result message; the toolchain for the
1918 belonging ports are now only built, if the port is enabled.
1920 * support/regression/*: all output is written in directory gen, because
1921 the fwk and ports directories don't livet in the build tree using vpath
1923 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1924 --disable-device-lib, added --enable-doc, added section VPATH
1926 * sim/ucsim/configure.in,
1927 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1928 z80 are enabled by default
1930 2006-04-24 Raphael Neider <rneider AT web.de>
1932 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1933 to config word, "pic14_"-prefixed some extern functions
1934 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1935 config word has been found
1936 * src/pic/device.h: added prototypes
1937 * src/pic/pcode.c: added "pic14_"-prefix where needed

2185 changes seem to cause (trigger?) problems with the build system.
2187 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
2189 * src/SDCCpeeph.c (operandsLiteral): new, added,

2198 2006-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
2200 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
2201 implemented patch 1120823 Thanks to Willy De la Court (normal
2202 interrupts need an interrupt number now if they are made critical),
2203 and enabled nesting of critical functions though not for gbz80
2204 (genCritical, genEndCritical): added functions
2205 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2206 * src/z80/mappings.i: added "ei" to all mappings
2208 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2210 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
2211 submitted by the Debian SDCC maintainer Aurelien Jarno:
2212 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
2213 archive with gcc 4.1 on mips and wrote the patch"
2215 2006-03-16 Raphael Neider <rneider AT web.de>
2217 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
2218 the left operand is shorter than the result (c* = lit-c* + int),
2220 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2223 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2225 * src/.version: increased version number to 2.5.5
2226 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2227 linking is done manually in pic16 port's _linkEdit,
2228 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2229 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2230 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2231 allocate asmop as AOP_ACC,
2232 (aopForRemat): added parameter 'bool result' in function declaration,
2233 (pic16_aopGet): return AOP_ACC when accessing WREG,
2234 (pic16_popGetTempReg): minor modification,
2235 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2236 'pic16_allocWithIdx',
2237 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
2238 calling function in absolute addresses,
2239 (genAssign): take into account AOP_ACC asmop,
2240 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
2241 * src/pic16/pcoderegs.c: some debug functions and lines added,
2242 * src/pic16/ralloc.c (decodeRegType): added but commented out,
2243 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2245 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2246 call to allocReg, not by manually allocating a new one,
2247 (pic16_assignRegisters): now before going through the register
2248 allocating functions mark all registers as free. This eliminates some
2249 side effects resulting from peephole parser done earlier in the backbone
2251 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
2253 * src/SDCCicode.c (geniCodeLogic),
2254 * src/SDCCast.c (decorateType): applied patch by Bernhard for rfe 1422617

2271 * src/mcs51/gen.h: changed asmop.freed:1 to asmop.allocated for tracking
2272 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
2273 (aopForSym, aopOp): increment asmop.allocated if reused,
2274 (freeAsmop): decrement asmop.allocated and check for zero instead of
2276 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2277 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
2278 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

2301 2006-03-06 Borut Razem <borut.razem AT siol.net>
2303 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2304 made the linker quiet
2306 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2308 * src/pic16/gen.c (genPcall): fixed bug #1443644
2309 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2310 which dumps before the function entry point a data byte which represents
2311 the number of the local variables used by the specified function, added
2312 'xinst' for initial support for Extended Instruction Support,
2313 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2314 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2315 port->fun_prefix anymore (may change later),
2316 (genFunction, genEndFunction): do not store/restore local registers for
2317 _main (this should take care the --main-return command line option in
2319 (genOr): removed some legacy pic-port instructions,
2320 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2321 performing operations with SFR's causes data to be written more than
2322 once to each SFR. Perhaps SFRs should be handled in special cases...
2323 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2325 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2326 into account for stack starting position,
2327 (struct OPTIONS pic16_optionsTable): added command line argument
2328 --extended or -y for Extended Instruction Support,
2329 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2330 (deassignLRs): *** perhaps the most important change, old 'for' code
2331 (commented out for reference), didn't account for some registers which
2332 were left marked 'not free' after a pointer operation. The change
2333 reduces register usage a lot in some cases
2335 2006-03-04 Borut Razem <borut.razem AT siol.net>

4719 but as registers instead (AOP_REG) using the fReturnIdx array,
4720 * (pic16_freeAsmop): remove the freed register from the
4721 _G.sregsAlloc field,
4722 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4723 a compare of 'WREG',
4724 * (pic16_popGetTempRegCond): changed function prototype, now
4725 function takes also a bitVector argument v which holds the current
4726 set of registers that are allocated for stack access by aopForSym,
4727 registers allocated in aopForSym for accessing stack symbols are not
4728 any more part of the functions usedRegs field,
4729 * (genCall): some times aopOp is called for a stack variable to be
4730 send, aopForSym might perform the push, if this is true make sure
4731 that genCall doesn't push the variable twice by testing _G.resDirect,
4732 * (genFunction): changed testing for unspecified interrupt number
4733 from 256 to INTNO_UNSPEC,
4734 * modified selection scheme of frame pointer generation. Previously
4735 if function did use local registers a frame pointer was generated,
4736 now a frame pointer is generated only if function has arguments
4737 (that need PLUSW2 register access), or has stack arguments, or the
4738 compiler is not instructed to omit the frame pointer,
4739 * (genEndFunction): before restoring local registers that were saved
4740 in the function preamble, also restore the registers that *might*
4741 have been allocated for stack access,
4742 * (genRet): removed some old comments,
4743 * (genCmp, the active (RN's) version): added a call to the
4744 pic16_genCmp_special function to perform the compare with a more
4745 robust and optimized way,
4746 * (genInline): a feature has been added in inline code generation,
4747 which allows a wildcard variable substitution when writing inline
4748 assembly. Code is incomplete and experimental therefore undocumented,
4749 * (genCast): changed order of aopOp for result and right to allow
4750 aopForSym to directly load the result if possible,
4751 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4752 perform an optimized compare on some selected special occasions,
4753 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4754 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4755 generate an IVT any more,
4756 * src/pic16/main.c (pic16_optionsTable): added command line option
4758 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4759 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4761 * src/pic16/NOTES: Raphael Neider added in list of active developers
4762 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4763 jumptable_end to prevent bug #,
4764 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4765 inCond and outCond fields,
4766 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4767 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4768 turn off register spilling,
4769 * (packRegsForOneUse): synced with other ports' versions although it
4770 is not used currently,
4771 * (pic16_packRegisters): added an optimization while reading
4772 structure bitfields, some registers may be saved (malloc code is
4773 decreased by 80 bytes)
4775 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4777 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4778 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4779 this can be optimized more?
4781 2005-03-10 Raphael Neider <rneider AT web.de>
4783 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4784 genNearPointerGet): (hopefully) fixed access to bitfields via
4785 pointers (p->bitN = x; and x = p->bitN; failed)

5111 access stack and frame pointers. They are initially assigned to
5112 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
5113 accessing SFRs. Updated all occurences of modification of stack or
5114 frame pointer in gen.c and pcode.c,
5115 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
5116 assigning of a literal value to pointers,

5420 generated for switch statements. For now you need to set the
5421 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5422 Now 4 algorithms for mcs51 jumptable generation are used:
5423 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5424 addresses loaded pc-relative for up to 112 cases and stack-pushing
5425 target addresses loaded with offset from dptr for up to 256 cases.

5457 * added libc directory. The current version of LibC contains string
5458 functions, ctype functions and macros and some functions of the
5459 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5460 be extensively tested in the future. Standard disclaimer here.

5474 * (genCmp): experimental code for new genCmp which uses PIC18's
5475 special compare&skip instructions. Initial tests fail some times
5476 with variables grater than 1 byte in size, so new code is disabled,
5477 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5479 * (genCast): began a fix to optimize the casting of a bit to another
5480 bit, now assigning a bitfield to another bitfield will fail, sorry,

5495 * src/pic16/ralloc.c (allocReg): add preliminary support for
5496 supporting a limited set of temporary registers,
5498 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8505 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8506 loaded with the linker search paths (-L arguments) and the libraries
8507 to be linked with the current source (-l arguments). Changes
8508 currently will affect only the pic16 port.
8509 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8510 include path the port specific paths and port specific libraries,
8511 * gplink command now contains the $3 argument,
8512 * src/pic16/device.h,
8513 * src/pic16/device.c,: structure PIC_device is made public and
8514 renamed to PIC16_device, the same for variable Pics which is renamed

8529 Documenting changes from previous commits.
8530 * configure.in (version 1.56),
8531 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8532 when generating output files to configure the pic16 library,
8533 but now I've commented it out, since gputils aren't installed in the
8534 SF compile farm, so library won't compile
8536 * device/lib/Makefile.in (version 1.56): initially I've added in
8537 target 'all' the prerequestive 'model-pic16' so it compiled the
8538 pic16 library, but now I've commented it out for the same reasons
8540 * added targets 'model-pic16' and 'objects-pic16' to compile the
8542 * added target 'port-specific-objects-pic16' to handle the
8543 generated libraries and copy them into the build/ directory
8544 * added target 'clean-intermediate-pic16' to clean intermediate
8545 files into pic16 directory
8546 * in target 'installdirs' added line to create directory pic16 in

8568 option so that it actually works. Made it specific to the z80, since
8569 the gbz80 doesn't have these kinds of I/O ports.
8571 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8795 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8797 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8798 (default behaviour).
8800 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8802 A python script to validate compiler diagnostic messages. It can be
8803 used to verify that sdcc complains about bad c source code and
8804 gives a good location of the error.
8805 * support/valdiag/Makefile,
8806 * support/valdiag/valdiag.py,
8807 * support/valdiag/tests/*

8824 Bug reported from Jesus Calvino-Fraga
8826 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8828 * sdcc.spec: updated
8829 * device/include/Makefile.in: don't install CVS directories
8830 * device/lib/Makefile.in: added removal of CVS directories after install
8831 * doc/Makefile: fixed install, added local_icons
8832 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8833 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8834 * src/ds390/gen.c (genRightShift): fixed bug #870788
8835 * src/SDCCast.c (decorateType): fixed bug #870781
8837 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8839 PIC16 port related changes:
8840 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8841 added variable stackPos,
8843 * gen.c: genCall, assignResultValue: added support for
8844 pushing/retrieving function parameters to/from stack,
8845 genFunction,genEndFunction: setup stack frame for the
8847 genAddrOf: will be changed according to bug 863624
8849 * added files genutils.c and genutils.h which contain gen*
8850 debugged and optimised functions extracted from gen.c
8852 * glue.c: added variable 'externs' which holds extern symbols,
8853 pic16emitRegularMap: is modified to properly handle relocatable
8854 symbols under the new scheme,
8855 pic16createInterruptVect: is modified
8856 pic16printPublics: is modified to emit 'global' assembler directives,
8857 added pic16_printExterns to print extern symbols,
8858 pic16glue: initializes stack/frame pointer in the beginning of
8859 the assembly output. Temporary hack, will be corrected later,
8860 because gplink yet does not support stack and SDCC does not
8861 yet support a type of crt0.o object to create the final binary.
8863 * Removed many lines that contain 8051 legacy code.
8864 * The code is finally placed under a 'code' directive.
8865 * Added port specific options.
8867 * _process_pragma: simplified since now we do not need *special*
8868 include file to define SFR registers. But a separate header
8869 will be needed. This will be developed later.
8870 * _pic16_parseOptions: added, parses port specific options:
8871 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8872 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8873 --preplace-udata-with=
8875 * _pic16_setDefaultOptions: modified to initialize section names,
8876 but hack is temporarly out of order since it needs improvement.
8877 * _pic16_genAssemblerPreamble: configuration words are emitted by
8878 their address instead of their name. This part is incomplete and
8879 supports only the 18Fxx2 devices. Other devices will emit an error
8880 during assembly since they do not contain the same set of config
8882 * _pic16_genIVT: is modified,
8884 * pcode.c: added definitions for some hardware registers that are needed
8886 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8887 All PCI entries are updated. Now LFSR is supported.
8888 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8889 * added pic16_newpCodeOpLit2 to support instructions with
8890 two literal arguments
8891 * pic16_pCode2str: corrected code that emits assembler instructions
8892 with two literal operands and those that have an access bit modifier
8893 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8894 this fixes a bug which caused some labels to be lost, when an
8895 assembler directive was added, i.e. banksel,
8896 * pic16_FixRegisterBanking: improved logic that causes the insertion
8898 * InlineFunction: functions that are called once, are not any more
8899 inlined. This can be a port option in the future,
8901 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8903 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8904 hold the corresponding uninitialized symbols,
8905 * pic16_allocProcessorRegister: registers have explicit marked the
8907 * pic16_allocInternalRegister: registers are explicit marked as
8909 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8910 processing list, so bit registers were lost,
8913 * ralloc.h: added field 'accessBank' and original symbol operand
8914 in register definition,
8915 * removed the field isMapped from register definition,
8917 ** Several functions have been removed from various sources:
8918 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8919 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8920 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8921 pic16_assignRelocatableRegisters
8923 ** others have been introduced:
8924 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8925 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8927 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8929 * support/scripts/inc2h.pl: changed definition of BIT_AT
8930 to emit 'sbit at' instead of 'bit at'. This was a request.
8932 PIC16 port related preliminary changes:
8933 * gen.c: prefixed function popRegFromString with
8934 pic16_ and all references to it corrected
8935 * pcode.c: all pic16_pc_* hardware registers prefixed
8936 with underscore (_),
8937 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8938 * ralloc.c: newReg(): when register is REG_SFR then
8939 set address to rIdx,
8940 pic16_allocProcessorRegister(): marks register wasUsed=0
8941 pic16_writeUsedRegs(): added a call to assign processor
8942 registers via pic16_assignFixedRegisters
8944 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8946 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8947 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8948 variables in unused register banks. Also the SSEG is placed
8949 wherever there is enough space for it, and IDATA can be anywhere
8950 in internal RAM. For now compile using -Wl-Y[stack_size].
8951 The mem file is different for this option as well, since it
8952 makes no sense of talking about DSEG lenght.
8954 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8956 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8957 in certain cases, e.g. when ROM assignment, patch provided
8958 from Albert den Haan.

9948 * src/mcs51/gen.c (leftRightUseAcc),
9949 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
9950 iCode properly now. Use getSize instead of nRegs since a & b

9964 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9965 copied from genNearPointerSet()
9966 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9967 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9968 If they pop r0/r1 they must be called in the opposite order than aopOp().
9969 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9970 (resp. --stack-auto), prepared for --xstack
9972 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9981 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9983 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9984 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9985 type for bits was changed. It resulted in bit variables becoming
9986 global, which is not permitted in PIC 14 assembly output.
9988 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9990 * doc/sdccman.lyx: various additions and updates. Rearranged sections

10003 A few small changes that speed up the peephole optimizer.
10007 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10009 Try to make the peephole optimizer smarter by maintaining
10010 an association between the assembly source code and the
10011 iCodes that originated them. Put this information to use
10012 with a new peephole rule condition "notVolatile" so that
10013 the rules can be aggressive yet still safe.
10018 * src/mcs51/peeph.def
10020 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10024 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
10025 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
10026 if the left or right operand symbols have the accuse flag set.
10028 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10030 Changed the type of the result of the ! (NOT) operator to char;
10031 previously it returned the same type as the source. This allows
10032 us to eliminate all the genFloatNot functions (all of its target
10033 implementations were very buggy) since !float can use the same
10036 * src/SDCCicode.c (ast2iCode): ! returns char

10045 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10046 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10047 during interrupts. Ensure WSAVE is located at a shared bank address.
10048 2. Fixed page selection in some places
10049 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10050 the registers name strings.
10051 4. Fixed "signed / unsigned compare" compiler warnings.
10052 5. The PIC port manages its own allocation of the general purpose
10053 registers, but makes no attempt to reuse them. As a result when
10054 compiling it soon runs out of general purpose registers. Some
10055 additional code was added to the files pcode.c and device.c to walk
10056 through the function call tree and rename the registers so that they
10066 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10067 genPlus() & genMinus() when the result is the same as left or right
10069 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10073 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10075 Made bitfield a distinct type from bit so that bitfields
10076 convert as per ANSI C and bits retain their traditional
10077 boolean style behaviour. Implemented bitfield support in
10085 * src/ds390/gen.c: bit v bitfield split
10086 * src/z80/gen.c: New support for bitfields
10087 * support/regression/tests/bitfields.c: reenabled z80,
10090 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10092 Rules 246.x, 247.x relate to bitfields, the others speed up
10093 access to xdata mapped I/O devices.
10095 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10097 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10099 Cleaned up genPackBits and genUnpackBits and added two helper
10100 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10101 for literal assignments in genPackBits (thanks to Frieder for
10107 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10109 Fixed bug #748310 (pointer to function type mishandled when the
10110 function name is omitted). Also fixed a SIGSEGV when a function
10111 attribute (reentrant, etc) is used on a non-function or on a
10112 function but misplaced before the parameter list.
10114 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10116 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10117 * support/Util/SDCCerr.h,
10118 * support/Util/SDCCerr.c: Added func attr misuse error msg
10120 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10122 Fixed bug #787649 by anonymous
10123 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10124 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10126 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10139 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10141 Made the constant following the "interrupt" keyword optional. If
10142 omitted, the function will not automatically be given an entry
10143 in the interrupt vector table (similar to #pragma NOIV, but
10144 less syntacticly kludgy). The interrupt number is also now
10145 range checked. Also fixed a bug in the high order bit example

10161 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10163 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10164 be re-activated by defining REDUCE_LITERALS)
10165 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10166 unsigned, but are signed by default
10167 * src/SDCCval.c (constVal): rearranged
10168 * src/SDCCval.c (valMod): preliminary fix
10169 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10209 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10210 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10211 constants are unsigned; added recognition of "u" flag for unsigned
10212 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10213 * src/SDCCval.c (valDiv, valMod): fixed signdness

10622 the regression tests I'm not brave enough to enable 245.b, 245.c
10623 * doc/sdccman.lyx: added latex preamble for hyperref package.
10624 Using pdflatex this will give you a hyperlinked pdf file with

10675 added if/endif conditional macros to remove options help
10676 messages from optionsTable when a port is not configured, added
10677 support for the PIc16 port in the ports table, when executing
10678 the compiler with no port specified on command line, a default
10679 port is selected with the new macro DEFAULT_PORT which is
10680 defined in port.h, in setDefaultOptions() linkOptions is removed
10681 from initialization assignment, since now it is a set,
10682 parseCmdLine uses setParseWithComma for linkOptions, in
10683 linkEdit() linkOptions are accessed with new function indexSet()
10684 which returns the i'th item of a set variable. See SDCCset.c, in
10685 linkEdit() when calling buildCmdLine(), added linkOptions as
10686 last argument. Now users can pass arguments to gplink via the
10687 -Wl option, main() uses pic16glue() to glue up pic16 programs

10700 * src/pic16/main.c: __config directives are commented out to stop
10701 gpasm complaining and test the linkage with gplink, _linkCmd and
10702 _asmCmd changed to be more gplink and gpasm friendly
10703 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10704 produced an error when parsed, peep rule 12 is added to utilize
10705 movff, but it is commented out since the pCode does not support
10706 yet a command with 2 address arguments
10708 2003-05-18 <johan AT balder>
10710 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11747 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11748 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests

11758 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11759 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11765 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11766 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11768 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11769 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11771 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11773 * in /sdcc/as/mcs51/ changed these files in order to create an
11774 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11775 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11776 following files to include the previous two files: aslink.dsp,
11777 Makefile.aslink, Makefile.bcc, and Makefile.in.
11779 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11780 .adb instead of .cdb
11782 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11784 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11785 value from option --iram-size.
11787 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11789 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11792 2002-09-18 <wiml AT hhhh.org>
11794 * SDCClrange.h: exposed setFromRange() and setToRange()
11795 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11796 packRegsForAccUse() (bug 542397)
11797 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11798 multiple times and emitting the fetch operations more than once
11799 added aopGetUsesAcc() function to allow binary operators to
11800 fetch their operands in the correct order; made genMinus() emit
11801 compact code for X = LITERAL - Y
11803 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11804 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11805 sprintf() in line 1267.
11807 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11808 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11811 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11812 Changes to aslink (All the changes are marked with 'JCF'):
11814 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11817 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11818 area BSEG. Also moves, if possible, the DATA area down into the internal
11819 ram so more space is available.
11821 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11824 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11825 not bytes. Function summary() which creates a memory usage summary
11826 file with extension .mem. Reports of overlaping stack and small stack
11827 size. If the space for the stack is less than 16 bytes aslink trows a
11830 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11831 the 8051. Option 'y' for memory summary output file.
11833 Changes to sdcc (All the changes are marked with 'JCF'):
11835 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11837 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11838 overlaying area for it (uses RegBankUsed[4]).
11840 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11841 bank zero as used by default. By default aslink locates the stack
11842 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11843 the creation of the .mem file. Delegates the allocation of data area
11844 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11845 the begining of the stack area to aslink.
11847 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11848 glue() in SDCCglue.c creates an area for it.
11850 2002-09-03 Borut Razem <borut.razem AT siol.net>
11851 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11852 sdcc/src/pic/glue.c:
11853 introduced atexit() handler for teporay files removal in case of
11854 errors, assertions, ...
11856 2002-08-29 Borut Razem <borut.razem AT siol.net>
11857 * sdcc/support/cpp2/auto-host_vc_in.h:
11858 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11859 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11860 Maybe there is a similar problem with BORLANDC? It should be checked!
11862 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11863 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11864 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11865 was not executed, and the compiler (cl) launched a warning:
11866 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11868 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11869 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11871 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11872 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11874 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11875 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11876 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11877 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11878 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11879 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11880 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11881 - added Release configuration in VS projects
11882 - review of compiler an linker options
11883 - VC .exe files are generated in bin_vc directory, not to interfere
11884 with binaries generated from other projects (cygwin, mingw, bcc ...)
11886 * sdcc/src/yacc.dsp: added
11888 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11889 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11890 and insert the version number definitions from .version
11892 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11894 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11895 added - genarate auto-host.h using auto-host_vc_in.h as template
11898 removed from CVS, generated automatically
11900 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11901 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11903 2002-08-11 Borut Razem <borut.razem AT siol.net>
11904 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11906 2002-08-10 Borut Razem <borut.razem AT siol.net>
11907 * src/SDCCmain.c (main):
11908 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11909 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11910 The consequence was that some temporary files were not removed.
11913 unification of code in functions tempfilename() and tempfile():
11914 function tempnam() is defined in Visual Studio 6.0 and .NET
11916 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11918 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11919 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11920 - removed compiler command line option /WX: Treats all warnings as errors
11921 - update a list of source files, included into the project
11923 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11924 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11925 changed project type to Generic Project so that can be correcly converted to VS.NET project
11927 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11929 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11931 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11933 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11934 added return 0 statements after assert() to make compiler happy
11936 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11937 added newline in the def file to keep MSC compiler satisfied
11939 * sdcc/src/z80/gen.c:
11940 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11941 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11942 - solved MSC error in function aopDump()
11944 * sdcc_vc.h: define PREFIX as "\\sdcc"
11946 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11947 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11949 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11950 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11951 - Rewrote the register banking algorithm.
11952 - Added pCode live-range analysis to registers (for now, only non-used and
11953 singly-used registers optimized away)
11955 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11957 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
11959 2002-05-10 Scott Dattalo <scott AT dattalo.com>
11960 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
11962 2002-04-22 Michael Hope <michaelh AT vroom>

11972 2002-04-15 Michael Hope <michaelh AT vroom>
11974 * device/lib/z80/printf.c (sprintf): Added.
11976 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11978 * src/z80/peeph.def: Added transpose redundent load rule.
