1865 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1867 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1868 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1870 One basic decision: e.g. src/clean.mk includes further files. In order
1871 to make this work there are two solutions:
1872 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1873 run configure on them. This way they can use
1874 'include $(srcdir)/port-clean.mk'
1875 - always include clean.mk by the Makefile at the same level. To avoid
1876 that `make clean` tries to include and build Makefile.dep the
1877 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1878 implemented, because now even `make uninstall` doesn't create
1879 Makefile.in. clean.mk could be eliminated by pasting it in
1882 * debugger/mcs51/Makefile.in: build own objects from library sources
1883 (SLIB, SDCC) in current directory
1885 * configure, configure.in: renamed --disable-device-lib-build in
1886 --disable-device-lib; added --enable-doc, the required tools are
1887 searched by configure; added result message; the toolchain for the
1888 belonging ports are now only built, if the port is enabled.
1890 * support/regression/*: all output is written in directory gen, because
1891 the fwk and ports directories don't livet in the build tree using vpath
1893 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1894 --disable-device-lib, added --enable-doc, added section VPATH
1896 * sim/ucsim/configure.in,
1897 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1898 z80 are enabled by default
1900 2006-04-24 Raphael Neider <rneider AT web.de>
1902 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1903 to config word, "pic14_"-prefixed some extern functions
1904 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1905 config word has been found
1906 * src/pic/device.h: added prototypes
1907 * src/pic/pcode.c: added "pic14_"-prefix where needed

2188 the left operand is shorter than the result (c* = lit-c* + int),
2190 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
2193 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2195 * src/.version: increased version number to 2.5.5
2196 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2197 linking is done manually in pic16 port's _linkEdit,
2198 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2199 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2200 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2201 allocate asmop as AOP_ACC,
2202 (aopForRemat): added parameter 'bool result' in function declaration,
2203 (pic16_aopGet): return AOP_ACC when accessing WREG,
2204 (pic16_popGetTempReg): minor modification,
2205 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2206 'pic16_allocWithIdx',
2207 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
2208 calling function in absolute addresses,
2209 (genAssign): take into account AOP_ACC asmop,
2210 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
2211 * src/pic16/pcoderegs.c: some debug functions and lines added,
2212 * src/pic16/ralloc.c (decodeRegType): added but commented out,
2213 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2215 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2216 call to allocReg, not by manually allocating a new one,
2217 (pic16_assignRegisters): now before going through the register
2218 allocating functions mark all registers as free. This eliminates some
2219 side effects resulting from peephole parser done earlier in the backbone
2221 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2241 * src/mcs51/gen.h: changed asmop.freed:1 to asmop.allocated for tracking
2242 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
2243 (aopForSym, aopOp): increment asmop.allocated if reused,
2244 (freeAsmop): decrement asmop.allocated and check for zero instead of
2246 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2247 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

2269 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
2271 2006-03-06 Borut Razem <borut.razem AT siol.net>
2273 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2274 made the linker quiet
2276 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2278 * src/pic16/gen.c (genPcall): fixed bug #1443644
2279 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2280 which dumps before the function entry point a data byte which represents
2281 the number of the local variables used by the specified function, added
2282 'xinst' for initial support for Extended Instruction Support,
2283 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2284 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2285 port->fun_prefix anymore (may change later),
2286 (genFunction, genEndFunction): do not store/restore local registers for
2287 _main (this should take care the --main-return command line option in
2289 (genOr): removed some legacy pic-port instructions,
2290 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2291 performing operations with SFR's causes data to be written more than
2292 once to each SFR. Perhaps SFRs should be handled in special cases...
2293 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2295 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2296 into account for stack starting position,
2297 (struct OPTIONS pic16_optionsTable): added command line argument
2298 --extended or -y for Extended Instruction Support,
2299 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2300 (deassignLRs): *** perhaps the most important change, old 'for' code
2301 (commented out for reference), didn't account for some registers which
2302 were left marked 'not free' after a pointer operation. The change
2303 reduces register usage a lot in some cases

4580 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4581 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4582 always available in leading double underscore form. The C99 support is
4583 mostly missing, but it's a start.
4584 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4585 reserved identifier "__data".

4655 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4658 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4660 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4661 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4663 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4665 * device/lib/printf_large.c: removed inline assembly for portability and
4666 readability. Use printf_fast if speed or size are more important.
4667 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4668 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4670 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4672 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4673 prevent compiler warning
4675 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4677 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4678 moved to level 0 and declared as static. Also they are explicit
4679 placed in access bank. This was necessery because some times they
4680 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4681 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4682 optimizations. Currently only compare to unsigned char is implemented,
4683 * src/pic16/gen.c: added fReturnIdx array,
4684 * (struct resolvedIfx) is moved to gen.h and made public,
4685 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4686 * (aopForSym): added an optimization to directly store in stack of
4687 the operand of a SEND iCode,
4688 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4689 but as registers instead (AOP_REG) using the fReturnIdx array,
4690 * (pic16_freeAsmop): remove the freed register from the
4691 _G.sregsAlloc field,
4692 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4693 a compare of 'WREG',
4694 * (pic16_popGetTempRegCond): changed function prototype, now
4695 function takes also a bitVector argument v which holds the current
4696 set of registers that are allocated for stack access by aopForSym,
4697 registers allocated in aopForSym for accessing stack symbols are not
4698 any more part of the functions usedRegs field,
4699 * (genCall): some times aopOp is called for a stack variable to be
4700 send, aopForSym might perform the push, if this is true make sure
4701 that genCall doesn't push the variable twice by testing _G.resDirect,
4702 * (genFunction): changed testing for unspecified interrupt number
4703 from 256 to INTNO_UNSPEC,
4704 * modified selection scheme of frame pointer generation. Previously
4705 if function did use local registers a frame pointer was generated,
4706 now a frame pointer is generated only if function has arguments
4707 (that need PLUSW2 register access), or has stack arguments, or the
4708 compiler is not instructed to omit the frame pointer,
4709 * (genEndFunction): before restoring local registers that were saved
4710 in the function preamble, also restore the registers that *might*
4711 have been allocated for stack access,
4712 * (genRet): removed some old comments,
4713 * (genCmp, the active (RN's) version): added a call to the
4714 pic16_genCmp_special function to perform the compare with a more
4715 robust and optimized way,
4716 * (genInline): a feature has been added in inline code generation,
4717 which allows a wildcard variable substitution when writing inline
4718 assembly. Code is incomplete and experimental therefore undocumented,
4719 * (genCast): changed order of aopOp for result and right to allow

5389 Adding support for replacing ljmps with sjmps in jumptables
5390 generated for switch statements. For now you need to set the
5391 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5392 Now 4 algorithms for mcs51 jumptable generation are used:
5393 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

5427 * added libc directory. The current version of LibC contains string
5428 functions, ctype functions and macros and some functions of the
5429 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5430 be extensively tested in the future. Standard disclaimer here.
5431 Library is not automatically build yet. But one can build it by

5443 * (pic16_storeForReturn): optimized return of 0,
5444 * (genCmp): experimental code for new genCmp which uses PIC18's
5445 special compare&skip instructions. Initial tests fail some times
5446 with variables grater than 1 byte in size, so new code is disabled,
5447 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5449 * (genCast): began a fix to optimize the casting of a bit to another
5450 bit, now assigning a bitfield to another bitfield will fail, sorry,

5459 and 1 for banking instruction,
5460 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5461 caused stop processing pCodes after a inline assembly block,
5462 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5464 registers when it shouldn't,
5465 * src/pic16/ralloc.c (allocReg): add preliminary support for
5466 supporting a limited set of temporary registers,
5468 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8476 loaded with the linker search paths (-L arguments) and the libraries
8477 to be linked with the current source (-l arguments). Changes
8478 currently will affect only the pic16 port.
8479 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8480 include path the port specific paths and port specific libraries,
8481 * gplink command now contains the $3 argument,
8482 * src/pic16/device.h,
8483 * src/pic16/device.c,: structure PIC_device is made public and
8484 renamed to PIC16_device, the same for variable Pics which is renamed

8499 Documenting changes from previous commits.
8500 * configure.in (version 1.56),
8501 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8502 when generating output files to configure the pic16 library,
8503 but now I've commented it out, since gputils aren't installed in the
8504 SF compile farm, so library won't compile
8506 * device/lib/Makefile.in (version 1.56): initially I've added in
8507 target 'all' the prerequestive 'model-pic16' so it compiled the
8508 pic16 library, but now I've commented it out for the same reasons
8510 * added targets 'model-pic16' and 'objects-pic16' to compile the
8512 * added target 'port-specific-objects-pic16' to handle the
8513 generated libraries and copy them into the build/ directory
8514 * added target 'clean-intermediate-pic16' to clean intermediate
8515 files into pic16 directory
8516 * in target 'installdirs' added line to create directory pic16 in

8720 directive when no overlay data exist
8721 * (picglue): modified to emit uninitialized data segment
8722 according to udata_section_name

8761 * src/SDCCast.c (decorateType),
8762 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
8763 LEFT_OP (left shift)
8765 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8767 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8768 (default behaviour).
8770 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8772 A python script to validate compiler diagnostic messages. It can be
8773 used to verify that sdcc complains about bad c source code and
8774 gives a good location of the error.
8775 * support/valdiag/Makefile,
8776 * support/valdiag/valdiag.py,
8777 * support/valdiag/tests/*
8779 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8790 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8792 * src/common.h: added ifndef/define/endif macros
8793 around the header file.
8794 Bug reported from Jesus Calvino-Fraga
8796 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8798 * sdcc.spec: updated
8799 * device/include/Makefile.in: don't install CVS directories
8800 * device/lib/Makefile.in: added removal of CVS directories after install
8801 * doc/Makefile: fixed install, added local_icons
8802 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8803 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8804 * src/ds390/gen.c (genRightShift): fixed bug #870788
8805 * src/SDCCast.c (decorateType): fixed bug #870781
8807 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8809 PIC16 port related changes:
8810 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8811 added variable stackPos,
8813 * gen.c: genCall, assignResultValue: added support for
8814 pushing/retrieving function parameters to/from stack,
8815 genFunction,genEndFunction: setup stack frame for the
8817 genAddrOf: will be changed according to bug 863624
8819 * added files genutils.c and genutils.h which contain gen*
8820 debugged and optimised functions extracted from gen.c
8822 * glue.c: added variable 'externs' which holds extern symbols,
8823 pic16emitRegularMap: is modified to properly handle relocatable
8824 symbols under the new scheme,
8825 pic16createInterruptVect: is modified
8826 pic16printPublics: is modified to emit 'global' assembler directives,
8827 added pic16_printExterns to print extern symbols,
8828 pic16glue: initializes stack/frame pointer in the beginning of
8829 the assembly output. Temporary hack, will be corrected later,
8830 because gplink yet does not support stack and SDCC does not
8831 yet support a type of crt0.o object to create the final binary.
8833 * Removed many lines that contain 8051 legacy code.
8834 * The code is finally placed under a 'code' directive.
8835 * Added port specific options.
8837 * _process_pragma: simplified since now we do not need *special*
8838 include file to define SFR registers. But a separate header
8839 will be needed. This will be developed later.
8840 * _pic16_parseOptions: added, parses port specific options:
8841 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8842 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8843 --preplace-udata-with=
8845 * _pic16_setDefaultOptions: modified to initialize section names,
8846 but hack is temporarly out of order since it needs improvement.
8847 * _pic16_genAssemblerPreamble: configuration words are emitted by
8848 their address instead of their name. This part is incomplete and
8849 supports only the 18Fxx2 devices. Other devices will emit an error
8850 during assembly since they do not contain the same set of config
8852 * _pic16_genIVT: is modified,
8854 * pcode.c: added definitions for some hardware registers that are needed
8856 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8857 All PCI entries are updated. Now LFSR is supported.
8858 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8859 * added pic16_newpCodeOpLit2 to support instructions with
8860 two literal arguments
8861 * pic16_pCode2str: corrected code that emits assembler instructions
8862 with two literal operands and those that have an access bit modifier
8863 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8864 this fixes a bug which caused some labels to be lost, when an
8865 assembler directive was added, i.e. banksel,
8866 * pic16_FixRegisterBanking: improved logic that causes the insertion
8868 * InlineFunction: functions that are called once, are not any more
8869 inlined. This can be a port option in the future,
8871 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8873 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8874 hold the corresponding uninitialized symbols,
8875 * pic16_allocProcessorRegister: registers have explicit marked the
8877 * pic16_allocInternalRegister: registers are explicit marked as
8879 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8880 processing list, so bit registers were lost,
8883 * ralloc.h: added field 'accessBank' and original symbol operand
8884 in register definition,
8885 * removed the field isMapped from register definition,
8887 ** Several functions have been removed from various sources:
8888 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8889 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8890 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8891 pic16_assignRelocatableRegisters
8893 ** others have been introduced:
8894 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8895 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8897 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8899 * support/scripts/inc2h.pl: changed definition of BIT_AT
8900 to emit 'sbit at' instead of 'bit at'. This was a request.
8902 PIC16 port related preliminary changes:
8903 * gen.c: prefixed function popRegFromString with
8904 pic16_ and all references to it corrected
8905 * pcode.c: all pic16_pc_* hardware registers prefixed
8906 with underscore (_),
8907 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8908 * ralloc.c: newReg(): when register is REG_SFR then
8909 set address to rIdx,
8910 pic16_allocProcessorRegister(): marks register wasUsed=0
8911 pic16_writeUsedRegs(): added a call to assign processor
8912 registers via pic16_assignFixedRegisters
8914 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8916 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8917 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8918 variables in unused register banks. Also the SSEG is placed
8919 wherever there is enough space for it, and IDATA can be anywhere
8920 in internal RAM. For now compile using -Wl-Y[stack_size].
8921 The mem file is different for this option as well, since it
8922 makes no sense of talking about DSEG lenght.
8924 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8926 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8927 in certain cases, e.g. when ROM assignment, patch provided
8928 from Albert den Haan.

9169 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9171 * src/SDCCast.c (decorateType): disabled a transformation I added in
9172 revision 1.188 (access to fields of a structure at an absolute address);
9173 it breaks with bitfields, extern declarations, and gcse analysis.
9174 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9175 could be assigned through a pointer, so don't complain.
9176 * src/SDCCast.c (astErrors),
9178 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
9180 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

9836 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9838 Fixed bug #621531 (const & volatile confusion in the type chain).
9839 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
9840 refer to the const or volatile state of the pointer itself.

9917 and JUMPTABLE iCodes properly now (worked by accident before)
9918 * src/mcs51/gen.c (leftRightUseAcc),
9919 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
9920 iCode properly now. Use getSize instead of nRegs since a & b

9933 fetching of the pointer
9934 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9935 copied from genNearPointerSet()
9936 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9937 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9938 If they pop r0/r1 they must be called in the opposite order than aopOp().
9939 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9940 (resp. --stack-auto), prepared for --xstack
9942 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9951 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9953 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9954 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9955 type for bits was changed. It resulted in bit variables becoming
9956 global, which is not permitted in PIC 14 assembly output.
9958 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9960 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9973 A few small changes that speed up the peephole optimizer.
9977 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9979 Try to make the peephole optimizer smarter by maintaining
9980 an association between the assembly source code and the
9981 iCodes that originated them. Put this information to use
9982 with a new peephole rule condition "notVolatile" so that
9983 the rules can be aggressive yet still safe.
9988 * src/mcs51/peeph.def
9990 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9994 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9995 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9996 if the left or right operand symbols have the accuse flag set.
9998 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10000 Changed the type of the result of the ! (NOT) operator to char;
10001 previously it returned the same type as the source. This allows
10002 us to eliminate all the genFloatNot functions (all of its target
10003 implementations were very buggy) since !float can use the same
10006 * src/SDCCicode.c (ast2iCode): ! returns char

10015 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10016 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10017 during interrupts. Ensure WSAVE is located at a shared bank address.
10018 2. Fixed page selection in some places
10019 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10020 the registers name strings.
10021 4. Fixed "signed / unsigned compare" compiler warnings.
10022 5. The PIC port manages its own allocation of the general purpose
10023 registers, but makes no attempt to reuse them. As a result when
10024 compiling it soon runs out of general purpose registers. Some
10025 additional code was added to the files pcode.c and device.c to walk
10026 through the function call tree and rename the registers so that they
10036 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10037 genPlus() & genMinus() when the result is the same as left or right

10043 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10045 Made bitfield a distinct type from bit so that bitfields
10046 convert as per ANSI C and bits retain their traditional
10047 boolean style behaviour. Implemented bitfield support in
10055 * src/ds390/gen.c: bit v bitfield split
10056 * src/z80/gen.c: New support for bitfields
10057 * support/regression/tests/bitfields.c: reenabled z80,
10060 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10062 Rules 246.x, 247.x relate to bitfields, the others speed up
10063 access to xdata mapped I/O devices.
10065 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10067 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10069 Cleaned up genPackBits and genUnpackBits and added two helper
10070 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10071 for literal assignments in genPackBits (thanks to Frieder for
10077 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10079 Fixed bug #748310 (pointer to function type mishandled when the
10080 function name is omitted). Also fixed a SIGSEGV when a function
10081 attribute (reentrant, etc) is used on a non-function or on a
10082 function but misplaced before the parameter list.
10084 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10086 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10087 * support/Util/SDCCerr.h,

10090 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10092 Fixed bug #787649 by anonymous
10093 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10094 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10096 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10109 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10111 Made the constant following the "interrupt" keyword optional. If
10112 omitted, the function will not automatically be given an entry
10113 in the interrupt vector table (similar to #pragma NOIV, but
10114 less syntacticly kludgy). The interrupt number is also now
10115 range checked. Also fixed a bug in the high order bit example

10131 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10133 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10134 be re-activated by defining REDUCE_LITERALS)
10135 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10136 unsigned, but are signed by default
10137 * src/SDCCval.c (constVal): rearranged
10138 * src/SDCCval.c (valMod): preliminary fix
10139 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10179 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10180 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10181 constants are unsigned; added recognition of "u" flag for unsigned
10182 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10183 * src/SDCCval.c (valDiv, valMod): fixed signdness

10646 messages from optionsTable when a port is not configured, added
10647 support for the PIc16 port in the ports table, when executing
10648 the compiler with no port specified on command line, a default
10649 port is selected with the new macro DEFAULT_PORT which is
10650 defined in port.h, in setDefaultOptions() linkOptions is removed
10651 from initialization assignment, since now it is a set,
10652 parseCmdLine uses setParseWithComma for linkOptions, in
10653 linkEdit() linkOptions are accessed with new function indexSet()
10654 which returns the i'th item of a set variable. See SDCCset.c, in
10655 linkEdit() when calling buildCmdLine(), added linkOptions as
10656 last argument. Now users can pass arguments to gplink via the
10657 -Wl option, main() uses pic16glue() to glue up pic16 programs

10671 gpasm complaining and test the linkage with gplink, _linkCmd and
10672 _asmCmd changed to be more gplink and gpasm friendly
10673 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10674 produced an error when parsed, peep rule 12 is added to utilize
10675 movff, but it is commented out since the pCode does not support
10676 yet a command with 2 address arguments
10678 2003-05-18 <johan AT balder>
10680 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11715 * src/SDCCicode.c: fixed array add
11717 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11718 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests

11728 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11729 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11732 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11733 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11735 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11736 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11738 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11739 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11741 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11743 * in /sdcc/as/mcs51/ changed these files in order to create an
11744 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11745 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11746 following files to include the previous two files: aslink.dsp,
11747 Makefile.aslink, Makefile.bcc, and Makefile.in.
11749 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11750 .adb instead of .cdb
11752 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11754 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11755 value from option --iram-size.
11757 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11759 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11762 2002-09-18 <wiml AT hhhh.org>
11764 * SDCClrange.h: exposed setFromRange() and setToRange()
11765 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11766 packRegsForAccUse() (bug 542397)
11767 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11768 multiple times and emitting the fetch operations more than once
11769 added aopGetUsesAcc() function to allow binary operators to
11770 fetch their operands in the correct order; made genMinus() emit
11771 compact code for X = LITERAL - Y
11773 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11774 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11775 sprintf() in line 1267.
11777 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11778 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11781 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11782 Changes to aslink (All the changes are marked with 'JCF'):
11784 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11787 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11788 area BSEG. Also moves, if possible, the DATA area down into the internal
11789 ram so more space is available.
11791 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11794 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11795 not bytes. Function summary() which creates a memory usage summary
11796 file with extension .mem. Reports of overlaping stack and small stack
11797 size. If the space for the stack is less than 16 bytes aslink trows a
11800 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11801 the 8051. Option 'y' for memory summary output file.
11803 Changes to sdcc (All the changes are marked with 'JCF'):
11805 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11807 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11808 overlaying area for it (uses RegBankUsed[4]).
11810 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11811 bank zero as used by default. By default aslink locates the stack
11812 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11813 the creation of the .mem file. Delegates the allocation of data area
11814 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11815 the begining of the stack area to aslink.
11817 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11818 glue() in SDCCglue.c creates an area for it.
11820 2002-09-03 Borut Razem <borut.razem AT siol.net>
11821 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11822 sdcc/src/pic/glue.c:
11823 introduced atexit() handler for teporay files removal in case of
11824 errors, assertions, ...
11826 2002-08-29 Borut Razem <borut.razem AT siol.net>
11827 * sdcc/support/cpp2/auto-host_vc_in.h:
11828 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11829 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11830 Maybe there is a similar problem with BORLANDC? It should be checked!
11832 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11833 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11834 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11835 was not executed, and the compiler (cl) launched a warning:
11836 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11838 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11839 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11841 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11842 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11844 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11845 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11846 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11847 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11848 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11849 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11850 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11851 - added Release configuration in VS projects
11852 - review of compiler an linker options
11853 - VC .exe files are generated in bin_vc directory, not to interfere
11854 with binaries generated from other projects (cygwin, mingw, bcc ...)
11856 * sdcc/src/yacc.dsp: added
11858 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11859 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11860 and insert the version number definitions from .version
11862 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11864 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11865 added - genarate auto-host.h using auto-host_vc_in.h as template
11868 removed from CVS, generated automatically
11870 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11871 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11873 2002-08-11 Borut Razem <borut.razem AT siol.net>
11874 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11876 2002-08-10 Borut Razem <borut.razem AT siol.net>
11877 * src/SDCCmain.c (main):
11878 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11879 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11880 The consequence was that some temporary files were not removed.
11883 unification of code in functions tempfilename() and tempfile():
11884 function tempnam() is defined in Visual Studio 6.0 and .NET
11886 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11888 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11889 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11890 - removed compiler command line option /WX: Treats all warnings as errors
11891 - update a list of source files, included into the project
11893 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11894 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11895 changed project type to Generic Project so that can be correcly converted to VS.NET project
11897 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11899 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11901 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11903 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11904 added return 0 statements after assert() to make compiler happy
11906 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11907 added newline in the def file to keep MSC compiler satisfied
11909 * sdcc/src/z80/gen.c:
11910 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11911 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11912 - solved MSC error in function aopDump()
11914 * sdcc_vc.h: define PREFIX as "\\sdcc"
11916 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11917 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11919 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11920 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11921 - Rewrote the register banking algorithm.
11922 - Added pCode live-range analysis to registers (for now, only non-used and
11923 singly-used registers optimized away)
11925 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11927 * 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.

11950 * src/z80/main.c: Added force callee saves for jaune.
11952 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11954 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11956 2002-03-28 Johan Knol <johan AT balder>
11958 * src/SDCCval.c: fixed bug #532436
11960 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11962 Added "char *Processor" field to the port structure.
11965 Added -p option. Allows port dependent processor to be specified.
11968 Initialized the new field char *Processor field to NULL in all ports
11971 Compiler generated registers for interrupt context saving
11972 were not getting allocated.
11974 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11977 Fixed left shift. Will promote the left side of a left shift
11978 if a) left shifting more than size of operand or b) when assigned
11979 to something size > size of left side
11981 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11983 tons of changes. Register allocation has been
11984 rewritten. Added customization for the various PICs. Flow
11985 analysis is restructured. ...
11987 * src/pic/device.h:
11990 * src/pic/device.c:
11991 Added. device.c is a PIC port hack to accomodate variations
11994 2002-03-13 Michael Hope <michaelh AT vroom>
11996 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11998 2002-03-04 johanknol <johanknol AT manik>
12000 * /src/SDCCval.c: fixed
12002 const unsigned char arr[][2] = { { 0, 1 } };
12003 t18.c:1: error: Initializer element is not constant
12005 2002-03-04 bela <bela AT manik>
12007 * /device/include/mcs51reg.h:
