1860 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1862 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1863 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1865 One basic decision: e.g. src/clean.mk includes further files. In order
1866 to make this work there are two solutions:
1867 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1868 run configure on them. This way they can use
1869 'include $(srcdir)/port-clean.mk'
1870 - always include clean.mk by the Makefile at the same level. To avoid
1871 that `make clean` tries to include and build Makefile.dep the
1872 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1873 implemented, because now even `make uninstall` doesn't create
1874 Makefile.in. clean.mk could be eliminated by pasting it in
1877 * debugger/mcs51/Makefile.in: build own objects from library sources
1878 (SLIB, SDCC) in current directory
1880 * configure, configure.in: renamed --disable-device-lib-build in
1881 --disable-device-lib; added --enable-doc, the required tools are
1882 searched by configure; added result message; the toolchain for the
1883 belonging ports are now only built, if the port is enabled.
1885 * support/regression/*: all output is written in directory gen, because
1886 the fwk and ports directories don't livet in the build tree using vpath
1888 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1889 --disable-device-lib, added --enable-doc, added section VPATH
1891 * sim/ucsim/configure.in,
1892 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1893 z80 are enabled by default
1895 2006-04-24 Raphael Neider <rneider AT web.de>
1897 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1898 to config word, "pic14_"-prefixed some extern functions
1899 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1900 config word has been found
1901 * src/pic/device.h: added prototypes
1902 * src/pic/pcode.c: added "pic14_"-prefix where needed

2191 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2192 linking is done manually in pic16 port's _linkEdit,
2193 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2194 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2195 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2196 allocate asmop as AOP_ACC,
2197 (aopForRemat): added parameter 'bool result' in function declaration,
2198 (pic16_aopGet): return AOP_ACC when accessing WREG,
2199 (pic16_popGetTempReg): minor modification,
2200 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
2201 'pic16_allocWithIdx',
2202 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
2203 calling function in absolute addresses,
2204 (genAssign): take into account AOP_ACC asmop,
2205 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
2206 * src/pic16/pcoderegs.c: some debug functions and lines added,
2207 * src/pic16/ralloc.c (decodeRegType): added but commented out,
2208 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
2210 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2211 call to allocReg, not by manually allocating a new one,
2212 (pic16_assignRegisters): now before going through the register
2213 allocating functions mark all registers as free. This eliminates some
2214 side effects resulting from peephole parser done earlier in the backbone
2216 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
2218 * src/SDCCicode.c (geniCodeLogic),

2237 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
2238 (aopForSym, aopOp): increment asmop.allocated if reused,
2239 (freeAsmop): decrement asmop.allocated and check for zero instead of
2241 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
2242 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

2266 2006-03-06 Borut Razem <borut.razem AT siol.net>
2268 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
2269 made the linker quiet
2271 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
2273 * src/pic16/gen.c (genPcall): fixed bug #1443644
2274 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2275 which dumps before the function entry point a data byte which represents
2276 the number of the local variables used by the specified function, added
2277 'xinst' for initial support for Extended Instruction Support,
2278 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2279 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2280 port->fun_prefix anymore (may change later),
2281 (genFunction, genEndFunction): do not store/restore local registers for
2282 _main (this should take care the --main-return command line option in
2284 (genOr): removed some legacy pic-port instructions,
2285 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2286 performing operations with SFR's causes data to be written more than
2287 once to each SFR. Perhaps SFRs should be handled in special cases...
2288 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2290 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2291 into account for stack starting position,

2293 --extended or -y for Extended Instruction Support,
2294 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
2295 (deassignLRs): *** perhaps the most important change, old 'for' code
2296 (commented out for reference), didn't account for some registers which
2297 were left marked 'not free' after a pointer operation. The change
2298 reduces register usage a lot in some cases

4656 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4658 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4660 * device/lib/printf_large.c: removed inline assembly for portability and
4661 readability. Use printf_fast if speed or size are more important.
4662 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4663 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4665 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4667 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4668 prevent compiler warning
4670 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4672 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4673 moved to level 0 and declared as static. Also they are explicit
4674 placed in access bank. This was necessery because some times they
4675 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4676 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4677 optimizations. Currently only compare to unsigned char is implemented,
4678 * src/pic16/gen.c: added fReturnIdx array,
4679 * (struct resolvedIfx) is moved to gen.h and made public,
4680 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4681 * (aopForSym): added an optimization to directly store in stack of
4682 the operand of a SEND iCode,
4683 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4684 but as registers instead (AOP_REG) using the fReturnIdx array,
4685 * (pic16_freeAsmop): remove the freed register from the
4686 _G.sregsAlloc field,
4687 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4688 a compare of 'WREG',
4689 * (pic16_popGetTempRegCond): changed function prototype, now
4690 function takes also a bitVector argument v which holds the current
4691 set of registers that are allocated for stack access by aopForSym,
4692 registers allocated in aopForSym for accessing stack symbols are not
4693 any more part of the functions usedRegs field,
4694 * (genCall): some times aopOp is called for a stack variable to be
4695 send, aopForSym might perform the push, if this is true make sure
4696 that genCall doesn't push the variable twice by testing _G.resDirect,
4697 * (genFunction): changed testing for unspecified interrupt number
4698 from 256 to INTNO_UNSPEC,
4699 * modified selection scheme of frame pointer generation. Previously
4700 if function did use local registers a frame pointer was generated,
4701 now a frame pointer is generated only if function has arguments
4702 (that need PLUSW2 register access), or has stack arguments, or the
4703 compiler is not instructed to omit the frame pointer,
4704 * (genEndFunction): before restoring local registers that were saved
4705 in the function preamble, also restore the registers that *might*
4706 have been allocated for stack access,
4707 * (genRet): removed some old comments,
4708 * (genCmp, the active (RN's) version): added a call to the
4709 pic16_genCmp_special function to perform the compare with a more
4710 robust and optimized way,
4711 * (genInline): a feature has been added in inline code generation,
4712 which allows a wildcard variable substitution when writing inline
4713 assembly. Code is incomplete and experimental therefore undocumented,
4714 * (genCast): changed order of aopOp for result and right to allow
4715 aopForSym to directly load the result if possible,

5384 Adding support for replacing ljmps with sjmps in jumptables
5385 generated for switch statements. For now you need to set the
5386 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5387 Now 4 algorithms for mcs51 jumptable generation are used:
5388 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5389 addresses loaded pc-relative for up to 112 cases and stack-pushing
5390 target addresses loaded with offset from dptr for up to 256 cases.

5420 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5422 * added libc directory. The current version of LibC contains string
5423 functions, ctype functions and macros and some functions of the
5424 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5425 be extensively tested in the future. Standard disclaimer here.
5426 Library is not automatically build yet. But one can build it by
5427 invoking 'make' inside the libc directory.

5438 * (pic16_storeForReturn): optimized return of 0,
5439 * (genCmp): experimental code for new genCmp which uses PIC18's
5440 special compare&skip instructions. Initial tests fail some times
5441 with variables grater than 1 byte in size, so new code is disabled,
5442 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5444 * (genCast): began a fix to optimize the casting of a bit to another
5445 bit, now assigning a bitfield to another bitfield will fail, sorry,

5454 and 1 for banking instruction,
5455 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5456 caused stop processing pCodes after a inline assembly block,
5457 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5459 registers when it shouldn't,
5460 * src/pic16/ralloc.c (allocReg): add preliminary support for
5461 supporting a limited set of temporary registers,
5463 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5469 (genFunction): optimize RECEIVE iCodes in reentrant functions
5471 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8471 loaded with the linker search paths (-L arguments) and the libraries
8472 to be linked with the current source (-l arguments). Changes
8473 currently will affect only the pic16 port.
8474 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8475 include path the port specific paths and port specific libraries,
8476 * gplink command now contains the $3 argument,
8477 * src/pic16/device.h,
8478 * src/pic16/device.c,: structure PIC_device is made public and

8494 Documenting changes from previous commits.
8495 * configure.in (version 1.56),
8496 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8497 when generating output files to configure the pic16 library,
8498 but now I've commented it out, since gputils aren't installed in the
8499 SF compile farm, so library won't compile
8501 * device/lib/Makefile.in (version 1.56): initially I've added in
8502 target 'all' the prerequestive 'model-pic16' so it compiled the
8503 pic16 library, but now I've commented it out for the same reasons
8505 * added targets 'model-pic16' and 'objects-pic16' to compile the
8507 * added target 'port-specific-objects-pic16' to handle the
8508 generated libraries and copy them into the build/ directory
8509 * added target 'clean-intermediate-pic16' to clean intermediate
8510 files into pic16 directory
8511 * in target 'installdirs' added line to create directory pic16 in

8722 arguments via -W option
8723 * src/pic16/main.c: added $l in _asmCmd, changed extension for
8724 object file from '.rel' to '.o' in port->linker structure,

8757 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
8758 LEFT_OP (left shift)
8760 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8762 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8763 (default behaviour).
8765 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8767 A python script to validate compiler diagnostic messages. It can be
8768 used to verify that sdcc complains about bad c source code and
8769 gives a good location of the error.
8770 * support/valdiag/Makefile,
8771 * support/valdiag/valdiag.py,
8772 * support/valdiag/tests/*

8785 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8787 * src/common.h: added ifndef/define/endif macros
8788 around the header file.
8789 Bug reported from Jesus Calvino-Fraga
8791 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8793 * sdcc.spec: updated
8794 * device/include/Makefile.in: don't install CVS directories
8795 * device/lib/Makefile.in: added removal of CVS directories after install
8796 * doc/Makefile: fixed install, added local_icons
8797 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8798 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8799 * src/ds390/gen.c (genRightShift): fixed bug #870788

8802 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8804 PIC16 port related changes:
8805 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8806 added variable stackPos,
8808 * gen.c: genCall, assignResultValue: added support for
8809 pushing/retrieving function parameters to/from stack,
8810 genFunction,genEndFunction: setup stack frame for the
8812 genAddrOf: will be changed according to bug 863624
8814 * added files genutils.c and genutils.h which contain gen*
8815 debugged and optimised functions extracted from gen.c
8817 * glue.c: added variable 'externs' which holds extern symbols,
8818 pic16emitRegularMap: is modified to properly handle relocatable
8819 symbols under the new scheme,
8820 pic16createInterruptVect: is modified
8821 pic16printPublics: is modified to emit 'global' assembler directives,
8822 added pic16_printExterns to print extern symbols,
8823 pic16glue: initializes stack/frame pointer in the beginning of
8824 the assembly output. Temporary hack, will be corrected later,
8825 because gplink yet does not support stack and SDCC does not
8826 yet support a type of crt0.o object to create the final binary.
8828 * Removed many lines that contain 8051 legacy code.
8829 * The code is finally placed under a 'code' directive.
8830 * Added port specific options.
8832 * _process_pragma: simplified since now we do not need *special*
8833 include file to define SFR registers. But a separate header
8834 will be needed. This will be developed later.
8835 * _pic16_parseOptions: added, parses port specific options:
8836 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8837 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8838 --preplace-udata-with=
8840 * _pic16_setDefaultOptions: modified to initialize section names,
8841 but hack is temporarly out of order since it needs improvement.
8842 * _pic16_genAssemblerPreamble: configuration words are emitted by
8843 their address instead of their name. This part is incomplete and
8844 supports only the 18Fxx2 devices. Other devices will emit an error
8845 during assembly since they do not contain the same set of config
8847 * _pic16_genIVT: is modified,
8849 * pcode.c: added definitions for some hardware registers that are needed
8851 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8852 All PCI entries are updated. Now LFSR is supported.
8853 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8854 * added pic16_newpCodeOpLit2 to support instructions with
8855 two literal arguments
8856 * pic16_pCode2str: corrected code that emits assembler instructions
8857 with two literal operands and those that have an access bit modifier
8858 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8859 this fixes a bug which caused some labels to be lost, when an
8860 assembler directive was added, i.e. banksel,
8861 * pic16_FixRegisterBanking: improved logic that causes the insertion
8863 * InlineFunction: functions that are called once, are not any more
8864 inlined. This can be a port option in the future,
8866 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8868 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8869 hold the corresponding uninitialized symbols,
8870 * pic16_allocProcessorRegister: registers have explicit marked the
8872 * pic16_allocInternalRegister: registers are explicit marked as
8874 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8875 processing list, so bit registers were lost,
8878 * ralloc.h: added field 'accessBank' and original symbol operand
8879 in register definition,
8880 * removed the field isMapped from register definition,
8882 ** Several functions have been removed from various sources:
8883 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8884 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8885 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8886 pic16_assignRelocatableRegisters
8888 ** others have been introduced:
8889 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8890 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8892 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8894 * support/scripts/inc2h.pl: changed definition of BIT_AT
8895 to emit 'sbit at' instead of 'bit at'. This was a request.
8897 PIC16 port related preliminary changes:
8898 * gen.c: prefixed function popRegFromString with
8899 pic16_ and all references to it corrected
8900 * pcode.c: all pic16_pc_* hardware registers prefixed
8901 with underscore (_),
8902 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8903 * ralloc.c: newReg(): when register is REG_SFR then
8904 set address to rIdx,
8905 pic16_allocProcessorRegister(): marks register wasUsed=0
8906 pic16_writeUsedRegs(): added a call to assign processor
8907 registers via pic16_assignFixedRegisters
8909 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8911 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8912 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8913 variables in unused register banks. Also the SSEG is placed
8914 wherever there is enough space for it, and IDATA can be anywhere
8915 in internal RAM. For now compile using -Wl-Y[stack_size].
8916 The mem file is different for this option as well, since it
8917 makes no sense of talking about DSEG lenght.
8919 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8921 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8922 in certain cases, e.g. when ROM assignment, patch provided
8923 from Albert den Haan.

9164 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9166 * src/SDCCast.c (decorateType): disabled a transformation I added in
9167 revision 1.188 (access to fields of a structure at an absolute address);
9168 it breaks with bitfields, extern declarations, and gcse analysis.
9169 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9170 could be assigned through a pointer, so don't complain.
9171 * src/SDCCast.c (astErrors),
9173 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

9181 pre-processor macro, i.e. -DMCU=p18f452
9182 * src/pic16/ralloc.c: renamed packRegisters to pic16_packRegisters,
9183 and modified to handle 'cast' icode similarly to '=' icode

9912 and JUMPTABLE iCodes properly now (worked by accident before)
9913 * src/mcs51/gen.c (leftRightUseAcc),
9914 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
9915 iCode properly now. Use getSize instead of nRegs since a & b

9927 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9928 fetching of the pointer
9929 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9930 copied from genNearPointerSet()
9931 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9932 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9933 If they pop r0/r1 they must be called in the opposite order than aopOp().
9934 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9935 (resp. --stack-auto), prepared for --xstack

9946 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9948 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9949 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9950 type for bits was changed. It resulted in bit variables becoming
9951 global, which is not permitted in PIC 14 assembly output.
9953 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9955 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9968 A few small changes that speed up the peephole optimizer.
9972 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9974 Try to make the peephole optimizer smarter by maintaining
9975 an association between the assembly source code and the
9976 iCodes that originated them. Put this information to use
9977 with a new peephole rule condition "notVolatile" so that
9978 the rules can be aggressive yet still safe.
9983 * src/mcs51/peeph.def
9985 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9989 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9990 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9991 if the left or right operand symbols have the accuse flag set.
9993 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9995 Changed the type of the result of the ! (NOT) operator to char;
9996 previously it returned the same type as the source. This allows
9997 us to eliminate all the genFloatNot functions (all of its target
9998 implementations were very buggy) since !float can use the same
10001 * src/SDCCicode.c (ast2iCode): ! returns char

10010 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
10011 1. Interrupt would not compile properly. Ensure PCLATH register is saved
10012 during interrupts. Ensure WSAVE is located at a shared bank address.
10013 2. Fixed page selection in some places
10014 3. Fixed BTFSS/C to where necessary use registers directly and not simply
10015 the registers name strings.
10016 4. Fixed "signed / unsigned compare" compiler warnings.
10017 5. The PIC port manages its own allocation of the general purpose
10018 registers, but makes no attempt to reuse them. As a result when
10019 compiling it soon runs out of general purpose registers. Some
10020 additional code was added to the files pcode.c and device.c to walk
10021 through the function call tree and rename the registers so that they
10031 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
10032 genPlus() & genMinus() when the result is the same as left or right
10034 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10038 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10040 Made bitfield a distinct type from bit so that bitfields
10041 convert as per ANSI C and bits retain their traditional
10042 boolean style behaviour. Implemented bitfield support in
10050 * src/ds390/gen.c: bit v bitfield split
10051 * src/z80/gen.c: New support for bitfields
10052 * support/regression/tests/bitfields.c: reenabled z80,
10055 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10057 Rules 246.x, 247.x relate to bitfields, the others speed up
10058 access to xdata mapped I/O devices.
10060 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
10062 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10064 Cleaned up genPackBits and genUnpackBits and added two helper
10065 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
10066 for literal assignments in genPackBits (thanks to Frieder for
10072 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10074 Fixed bug #748310 (pointer to function type mishandled when the
10075 function name is omitted). Also fixed a SIGSEGV when a function
10076 attribute (reentrant, etc) is used on a non-function or on a
10077 function but misplaced before the parameter list.
10079 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
10081 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
10082 * support/Util/SDCCerr.h,
10083 * support/Util/SDCCerr.c: Added func attr misuse error msg
10085 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
10087 Fixed bug #787649 by anonymous
10088 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
10089 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
10091 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

10104 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10106 Made the constant following the "interrupt" keyword optional. If
10107 omitted, the function will not automatically be given an entry
10108 in the interrupt vector table (similar to #pragma NOIV, but
10109 less syntacticly kludgy). The interrupt number is also now
10110 range checked. Also fixed a bug in the high order bit example

10126 * src/SDCCsymt.c (computeType): literals are handled the same way as any
10128 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
10129 be re-activated by defining REDUCE_LITERALS)
10130 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
10131 unsigned, but are signed by default
10132 * src/SDCCval.c (constVal): rearranged
10133 * src/SDCCval.c (valMod): preliminary fix
10134 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10174 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
10175 * src/SDCCval.c (constVal): changed default to signed; hex and octal
10176 constants are unsigned; added recognition of "u" flag for unsigned
10177 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10178 * src/SDCCval.c (valDiv, valMod): fixed signdness

10641 messages from optionsTable when a port is not configured, added
10642 support for the PIc16 port in the ports table, when executing
10643 the compiler with no port specified on command line, a default
10644 port is selected with the new macro DEFAULT_PORT which is
10645 defined in port.h, in setDefaultOptions() linkOptions is removed
10646 from initialization assignment, since now it is a set,
10647 parseCmdLine uses setParseWithComma for linkOptions, in
10648 linkEdit() linkOptions are accessed with new function indexSet()
10649 which returns the i'th item of a set variable. See SDCCset.c, in
10650 linkEdit() when calling buildCmdLine(), added linkOptions as
10651 last argument. Now users can pass arguments to gplink via the
10652 -Wl option, main() uses pic16glue() to glue up pic16 programs

10666 gpasm complaining and test the linkage with gplink, _linkCmd and
10667 _asmCmd changed to be more gplink and gpasm friendly
10668 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10669 produced an error when parsed, peep rule 12 is added to utilize
10670 movff, but it is commented out since the pCode does not support
10671 yet a command with 2 address arguments

11730 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11731 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11733 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11734 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11736 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11738 * in /sdcc/as/mcs51/ changed these files in order to create an
11739 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11740 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11741 following files to include the previous two files: aslink.dsp,
11742 Makefile.aslink, Makefile.bcc, and Makefile.in.
11744 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11745 .adb instead of .cdb
11747 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11749 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11750 value from option --iram-size.
11752 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11754 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11757 2002-09-18 <wiml AT hhhh.org>
11759 * SDCClrange.h: exposed setFromRange() and setToRange()
11760 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11761 packRegsForAccUse() (bug 542397)
11762 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11763 multiple times and emitting the fetch operations more than once
11764 added aopGetUsesAcc() function to allow binary operators to
11765 fetch their operands in the correct order; made genMinus() emit
11766 compact code for X = LITERAL - Y
11768 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11769 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11770 sprintf() in line 1267.
11772 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11773 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11776 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11777 Changes to aslink (All the changes are marked with 'JCF'):
11779 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11782 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11783 area BSEG. Also moves, if possible, the DATA area down into the internal
11784 ram so more space is available.
11786 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11789 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11790 not bytes. Function summary() which creates a memory usage summary
11791 file with extension .mem. Reports of overlaping stack and small stack
11792 size. If the space for the stack is less than 16 bytes aslink trows a
11795 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11796 the 8051. Option 'y' for memory summary output file.
11798 Changes to sdcc (All the changes are marked with 'JCF'):
11800 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11802 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11803 overlaying area for it (uses RegBankUsed[4]).
11805 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11806 bank zero as used by default. By default aslink locates the stack
11807 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11808 the creation of the .mem file. Delegates the allocation of data area
11809 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11810 the begining of the stack area to aslink.
11812 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11813 glue() in SDCCglue.c creates an area for it.
11815 2002-09-03 Borut Razem <borut.razem AT siol.net>
11816 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11817 sdcc/src/pic/glue.c:
11818 introduced atexit() handler for teporay files removal in case of
11819 errors, assertions, ...
11821 2002-08-29 Borut Razem <borut.razem AT siol.net>
11822 * sdcc/support/cpp2/auto-host_vc_in.h:
11823 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11824 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11825 Maybe there is a similar problem with BORLANDC? It should be checked!
11827 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11828 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11829 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11830 was not executed, and the compiler (cl) launched a warning:
11831 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11833 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11834 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11836 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11837 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11839 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11840 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11841 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11842 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11843 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11844 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11845 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11846 - added Release configuration in VS projects
11847 - review of compiler an linker options
11848 - VC .exe files are generated in bin_vc directory, not to interfere
11849 with binaries generated from other projects (cygwin, mingw, bcc ...)
11851 * sdcc/src/yacc.dsp: added
11853 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11854 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11855 and insert the version number definitions from .version
11857 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11859 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11860 added - genarate auto-host.h using auto-host_vc_in.h as template
11863 removed from CVS, generated automatically
11865 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11866 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11868 2002-08-11 Borut Razem <borut.razem AT siol.net>
11869 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11871 2002-08-10 Borut Razem <borut.razem AT siol.net>
11872 * src/SDCCmain.c (main):
11873 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11874 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11875 The consequence was that some temporary files were not removed.
11878 unification of code in functions tempfilename() and tempfile():
11879 function tempnam() is defined in Visual Studio 6.0 and .NET
11881 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11883 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11884 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11885 - removed compiler command line option /WX: Treats all warnings as errors
11886 - update a list of source files, included into the project
11888 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11889 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11890 changed project type to Generic Project so that can be correcly converted to VS.NET project
11892 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11894 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11896 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11898 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11899 added return 0 statements after assert() to make compiler happy
11901 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11902 added newline in the def file to keep MSC compiler satisfied
11904 * sdcc/src/z80/gen.c:
11905 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11906 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11907 - solved MSC error in function aopDump()
11909 * sdcc_vc.h: define PREFIX as "\\sdcc"
11911 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11912 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11915 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11916 - Rewrote the register banking algorithm.
11917 - Added pCode live-range analysis to registers (for now, only non-used and
11918 singly-used registers optimized away)
11920 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11922 * 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.

11945 * src/z80/main.c: Added force callee saves for jaune.
11947 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11949 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11951 2002-03-28 Johan Knol <johan AT balder>
11953 * src/SDCCval.c: fixed bug #532436
11955 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11957 Added "char *Processor" field to the port structure.
11960 Added -p option. Allows port dependent processor to be specified.
11963 Initialized the new field char *Processor field to NULL in all ports
11966 Compiler generated registers for interrupt context saving
11967 were not getting allocated.
11969 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11972 Fixed left shift. Will promote the left side of a left shift
11973 if a) left shifting more than size of operand or b) when assigned
11974 to something size > size of left side
11976 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11978 tons of changes. Register allocation has been
11979 rewritten. Added customization for the various PICs. Flow
11980 analysis is restructured. ...
11982 * src/pic/device.h:
11985 * src/pic/device.c:
11986 Added. device.c is a PIC port hack to accomodate variations
11989 2002-03-13 Michael Hope <michaelh AT vroom>
11991 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11993 2002-03-04 johanknol <johanknol AT manik>
11995 * /src/SDCCval.c: fixed
11997 const unsigned char arr[][2] = { { 0, 1 } };
11998 t18.c:1: error: Initializer element is not constant
12000 2002-03-04 bela <bela AT manik>
12002 * /device/include/mcs51reg.h:
12003 ds89c420 register definition update
