80 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
82 Enabled VPATH feature: changed nearly all Makefiles (149 files).
83 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
85 One basic decision: e.g. src/clean.mk includes further files. In order
86 to make this work there are two solutions:
87 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
88 run configure on them. This way they can use
89 'include $(srcdir)/port-clean.mk'
90 - always include clean.mk by the Makefile at the same level. To avoid
91 that `make clean` tries to include and build Makefile.dep the
92 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
93 implemented, because now even `make uninstall` doesn't create
94 Makefile.in. clean.mk could be eliminated by pasting it in
97 * debugger/mcs51/Makefile.in: build own objects from library sources
98 (SLIB, SDCC) in current directory
100 * configure, configure.in: renamed --disable-device-lib-build in
101 --disable-device-lib; added --enable-doc, the required tools are
102 searched by configure; added result message; the toolchain for the
103 belonging ports are now only built, if the port is enabled.
105 * support/regression/*: all output is written in directory gen, because
106 the fwk and ports directories don't livet in the build tree using vpath
108 * doc/sdccman.lyx: renamed --disable-device-lib-build to
109 --disable-device-lib, added --enable-doc, added section VPATH
111 * sim/ucsim/configure.in,
112 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
113 z80 are enabled by default
115 2006-04-24 Raphael Neider <rneider AT web.de>
117 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
118 to config word, "pic14_"-prefixed some extern functions

120 config word has been found
121 * src/pic/device.h: added prototypes
122 * src/pic/pcode.c: added "pic14_"-prefix where needed

431 call to allocReg, not by manually allocating a new one,
432 (pic16_assignRegisters): now before going through the register
433 allocating functions mark all registers as free. This eliminates some
434 side effects resulting from peephole parser done earlier in the backbone

484 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
486 2006-03-06 Borut Razem <borut.razem AT siol.net>
488 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
489 made the linker quiet
491 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
493 * src/pic16/gen.c (genPcall): fixed bug #1443644
494 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
495 which dumps before the function entry point a data byte which represents
496 the number of the local variables used by the specified function, added
497 'xinst' for initial support for Extended Instruction Support,
498 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
499 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
500 port->fun_prefix anymore (may change later),

504 (genOr): removed some legacy pic-port instructions,
505 * src/pic16/genarith.c (genAddLit): re-enabled old code because
506 performing operations with SFR's causes data to be written more than

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

2793 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2794 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2795 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2796 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2797 always available in leading double underscore form. The C99 support is
2798 mostly missing, but it's a start.
2799 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2800 reserved identifier "__data".

2878 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2880 * device/lib/printf_large.c: removed inline assembly for portability and
2881 readability. Use printf_fast if speed or size are more important.
2882 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2883 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2885 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2887 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2888 prevent compiler warning
2890 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2892 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2893 moved to level 0 and declared as static. Also they are explicit
2894 placed in access bank. This was necessery because some times they
2895 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2896 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2897 optimizations. Currently only compare to unsigned char is implemented,
2898 * src/pic16/gen.c: added fReturnIdx array,
2899 * (struct resolvedIfx) is moved to gen.h and made public,
2900 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2901 * (aopForSym): added an optimization to directly store in stack of
2902 the operand of a SEND iCode,
2903 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2904 but as registers instead (AOP_REG) using the fReturnIdx array,
2905 * (pic16_freeAsmop): remove the freed register from the
2906 _G.sregsAlloc field,
2907 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2908 a compare of 'WREG',
2909 * (pic16_popGetTempRegCond): changed function prototype, now
2910 function takes also a bitVector argument v which holds the current
2911 set of registers that are allocated for stack access by aopForSym,
2912 registers allocated in aopForSym for accessing stack symbols are not
2913 any more part of the functions usedRegs field,
2914 * (genCall): some times aopOp is called for a stack variable to be
2915 send, aopForSym might perform the push, if this is true make sure
2916 that genCall doesn't push the variable twice by testing _G.resDirect,
2917 * (genFunction): changed testing for unspecified interrupt number
2918 from 256 to INTNO_UNSPEC,
2919 * modified selection scheme of frame pointer generation. Previously
2920 if function did use local registers a frame pointer was generated,
2921 now a frame pointer is generated only if function has arguments
2922 (that need PLUSW2 register access), or has stack arguments, or the
2923 compiler is not instructed to omit the frame pointer,
2924 * (genEndFunction): before restoring local registers that were saved
2925 in the function preamble, also restore the registers that *might*
2926 have been allocated for stack access,
2927 * (genRet): removed some old comments,
2928 * (genCmp, the active (RN's) version): added a call to the
2929 pic16_genCmp_special function to perform the compare with a more
2930 robust and optimized way,
2931 * (genInline): a feature has been added in inline code generation,
2932 which allows a wildcard variable substitution when writing inline
2933 assembly. Code is incomplete and experimental therefore undocumented,
2934 * (genCast): changed order of aopOp for result and right to allow
2935 aopForSym to directly load the result if possible,
2936 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2937 perform an optimized compare on some selected special occasions,
2938 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2939 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2940 generate an IVT any more,
2941 * src/pic16/main.c (pic16_optionsTable): added command line option
2943 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2944 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2946 * src/pic16/NOTES: Raphael Neider added in list of active developers
2947 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2948 jumptable_end to prevent bug #,
2949 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2950 inCond and outCond fields,
2951 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2952 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2953 turn off register spilling,
2954 * (packRegsForOneUse): synced with other ports' versions although it
2955 is not used currently,
2956 * (pic16_packRegisters): added an optimization while reading
2957 structure bitfields, some registers may be saved (malloc code is
2958 decreased by 80 bytes)
2960 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2962 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2963 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2964 this can be optimized more?
2966 2005-03-10 Raphael Neider <rneider AT web.de>
2968 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2969 genNearPointerGet): (hopefully) fixed access to bitfields via
2970 pointers (p->bitN = x; and x = p->bitN; failed)
2972 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3604 Adding support for replacing ljmps with sjmps in jumptables
3605 generated for switch statements. For now you need to set the
3606 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3607 Now 4 algorithms for mcs51 jumptable generation are used:
3608 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3609 addresses loaded pc-relative for up to 112 cases and stack-pushing
3610 target addresses loaded with offset from dptr for up to 256 cases.

3640 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3642 * added libc directory. The current version of LibC contains string
3643 functions, ctype functions and macros and some functions of the
3644 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3645 be extensively tested in the future. Standard disclaimer here.
3646 Library is not automatically build yet. But one can build it by
3647 invoking 'make' inside the libc directory.

3658 * (pic16_storeForReturn): optimized return of 0,
3659 * (genCmp): experimental code for new genCmp which uses PIC18's
3660 special compare&skip instructions. Initial tests fail some times
3661 with variables grater than 1 byte in size, so new code is disabled,
3662 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3664 * (genCast): began a fix to optimize the casting of a bit to another
3665 bit, now assigning a bitfield to another bitfield will fail, sorry,
3666 * src/pic16/main.c: disabled the use of lr-support feature,
3667 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3674 and 1 for banking instruction,
3675 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3676 caused stop processing pCodes after a inline assembly block,
3677 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3678 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3679 registers when it shouldn't,
3680 * src/pic16/ralloc.c (allocReg): add preliminary support for
3681 supporting a limited set of temporary registers,
3683 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3685 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3686 genDataPointerSet): ensure assignments always copy in MSB to LSB
3688 (loadRegFromAop): recognize CLRH optimization,
3689 (genFunction): optimize RECEIVE iCodes in reentrant functions
3691 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3693 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6604 * src/SDCCast.c: added an additional type flow in decorateType() of
6605 opposite direction, see feature request #860006; it's enabled at runtime
6606 by setting the environment variable SDCC_NEWTYPEFLOW
6607 * src/SDCCast.h: changed prototype of decorateType()

6691 loaded with the linker search paths (-L arguments) and the libraries
6692 to be linked with the current source (-l arguments). Changes
6693 currently will affect only the pic16 port.
6694 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6695 include path the port specific paths and port specific libraries,
6696 * gplink command now contains the $3 argument,
6697 * src/pic16/device.h,
6698 * src/pic16/device.c,: structure PIC_device is made public and

6714 Documenting changes from previous commits.
6715 * configure.in (version 1.56),
6716 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6717 when generating output files to configure the pic16 library,
6718 but now I've commented it out, since gputils aren't installed in the
6719 SF compile farm, so library won't compile
6721 * device/lib/Makefile.in (version 1.56): initially I've added in
6722 target 'all' the prerequestive 'model-pic16' so it compiled the
6723 pic16 library, but now I've commented it out for the same reasons
6725 * added targets 'model-pic16' and 'objects-pic16' to compile the
6727 * added target 'port-specific-objects-pic16' to handle the
6728 generated libraries and copy them into the build/ directory
6729 * added target 'clean-intermediate-pic16' to clean intermediate
6730 files into pic16 directory
6731 * in target 'installdirs' added line to create directory pic16 in

7034 * added files genutils.c and genutils.h which contain gen*
7035 debugged and optimised functions extracted from gen.c
7037 * glue.c: added variable 'externs' which holds extern symbols,
7038 pic16emitRegularMap: is modified to properly handle relocatable
7039 symbols under the new scheme,
7040 pic16createInterruptVect: is modified
7041 pic16printPublics: is modified to emit 'global' assembler directives,
7042 added pic16_printExterns to print extern symbols,
7043 pic16glue: initializes stack/frame pointer in the beginning of
7044 the assembly output. Temporary hack, will be corrected later,
7045 because gplink yet does not support stack and SDCC does not
7046 yet support a type of crt0.o object to create the final binary.
7048 * Removed many lines that contain 8051 legacy code.
7049 * The code is finally placed under a 'code' directive.
7050 * Added port specific options.
7052 * _process_pragma: simplified since now we do not need *special*
7053 include file to define SFR registers. But a separate header
7054 will be needed. This will be developed later.
7055 * _pic16_parseOptions: added, parses port specific options:
7056 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7057 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7058 --preplace-udata-with=
7060 * _pic16_setDefaultOptions: modified to initialize section names,
7061 but hack is temporarly out of order since it needs improvement.
7062 * _pic16_genAssemblerPreamble: configuration words are emitted by
7063 their address instead of their name. This part is incomplete and
7064 supports only the 18Fxx2 devices. Other devices will emit an error
7065 during assembly since they do not contain the same set of config
7067 * _pic16_genIVT: is modified,
7069 * pcode.c: added definitions for some hardware registers that are needed
7071 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7072 All PCI entries are updated. Now LFSR is supported.
7073 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7074 * added pic16_newpCodeOpLit2 to support instructions with
7075 two literal arguments
7076 * pic16_pCode2str: corrected code that emits assembler instructions
7077 with two literal operands and those that have an access bit modifier
7078 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7079 this fixes a bug which caused some labels to be lost, when an
7080 assembler directive was added, i.e. banksel,
7081 * pic16_FixRegisterBanking: improved logic that causes the insertion
7083 * InlineFunction: functions that are called once, are not any more
7084 inlined. This can be a port option in the future,
7086 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7088 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7089 hold the corresponding uninitialized symbols,
7090 * pic16_allocProcessorRegister: registers have explicit marked the
7092 * pic16_allocInternalRegister: registers are explicit marked as
7094 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7095 processing list, so bit registers were lost,
7098 * ralloc.h: added field 'accessBank' and original symbol operand
7099 in register definition,
7100 * removed the field isMapped from register definition,
7102 ** Several functions have been removed from various sources:
7103 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7104 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7105 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7106 pic16_assignRelocatableRegisters
7108 ** others have been introduced:
7109 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7110 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7112 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7114 * support/scripts/inc2h.pl: changed definition of BIT_AT
7115 to emit 'sbit at' instead of 'bit at'. This was a request.
7117 PIC16 port related preliminary changes:
7118 * gen.c: prefixed function popRegFromString with
7119 pic16_ and all references to it corrected
7120 * pcode.c: all pic16_pc_* hardware registers prefixed
7121 with underscore (_),
7122 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7123 * ralloc.c: newReg(): when register is REG_SFR then
7124 set address to rIdx,
7125 pic16_allocProcessorRegister(): marks register wasUsed=0
7126 pic16_writeUsedRegs(): added a call to assign processor
7127 registers via pic16_assignFixedRegisters
7129 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7131 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7132 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7133 variables in unused register banks. Also the SSEG is placed
7134 wherever there is enough space for it, and IDATA can be anywhere
7135 in internal RAM. For now compile using -Wl-Y[stack_size].
7136 The mem file is different for this option as well, since it
7137 makes no sense of talking about DSEG lenght.
7139 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7141 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7142 in certain cases, e.g. when ROM assignment, patch provided
7143 from Albert den Haan.

7384 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7386 * src/SDCCast.c (decorateType): disabled a transformation I added in
7387 revision 1.188 (access to fields of a structure at an absolute address);
7388 it breaks with bitfields, extern declarations, and gcse analysis.
7389 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7390 could be assigned through a pointer, so don't complain.
7391 * src/SDCCast.c (astErrors),
7393 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7493 2003-11-13 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7495 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
7496 uninitialized variables) for the mcs51. Set environment variable

8147 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8148 fetching of the pointer
8149 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8150 copied from genNearPointerSet()
8151 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8152 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8168 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8169 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8170 type for bits was changed. It resulted in bit variables becoming
8171 global, which is not permitted in PIC 14 assembly output.
8173 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8175 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8188 A few small changes that speed up the peephole optimizer.
8192 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8194 Try to make the peephole optimizer smarter by maintaining
8195 an association between the assembly source code and the
8196 iCodes that originated them. Put this information to use
8197 with a new peephole rule condition "notVolatile" so that
8198 the rules can be aggressive yet still safe.
8203 * src/mcs51/peeph.def
8205 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8209 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8210 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8211 if the left or right operand symbols have the accuse flag set.
8213 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8215 Changed the type of the result of the ! (NOT) operator to char;
8216 previously it returned the same type as the source. This allows
8217 us to eliminate all the genFloatNot functions (all of its target
8218 implementations were very buggy) since !float can use the same
8221 * src/SDCCicode.c (ast2iCode): ! returns char

8230 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8231 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8232 during interrupts. Ensure WSAVE is located at a shared bank address.
8233 2. Fixed page selection in some places
8234 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8235 the registers name strings.
8236 4. Fixed "signed / unsigned compare" compiler warnings.
8237 5. The PIC port manages its own allocation of the general purpose
8238 registers, but makes no attempt to reuse them. As a result when
8239 compiling it soon runs out of general purpose registers. Some
8240 additional code was added to the files pcode.c and device.c to walk
8241 through the function call tree and rename the registers so that they
8251 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8252 genPlus() & genMinus() when the result is the same as left or right

8258 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8260 Made bitfield a distinct type from bit so that bitfields
8261 convert as per ANSI C and bits retain their traditional
8262 boolean style behaviour. Implemented bitfield support in
8270 * src/ds390/gen.c: bit v bitfield split
8271 * src/z80/gen.c: New support for bitfields
8272 * support/regression/tests/bitfields.c: reenabled z80,
8275 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8277 Rules 246.x, 247.x relate to bitfields, the others speed up
8278 access to xdata mapped I/O devices.
8280 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8282 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8284 Cleaned up genPackBits and genUnpackBits and added two helper
8285 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8286 for literal assignments in genPackBits (thanks to Frieder for
8292 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8294 Fixed bug #748310 (pointer to function type mishandled when the
8295 function name is omitted). Also fixed a SIGSEGV when a function
8296 attribute (reentrant, etc) is used on a non-function or on a
8297 function but misplaced before the parameter list.
8299 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8301 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8302 * support/Util/SDCCerr.h,
8303 * support/Util/SDCCerr.c: Added func attr misuse error msg

8324 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8326 Made the constant following the "interrupt" keyword optional. If
8327 omitted, the function will not automatically be given an entry
8328 in the interrupt vector table (similar to #pragma NOIV, but
8329 less syntacticly kludgy). The interrupt number is also now
8330 range checked. Also fixed a bug in the high order bit example

8338 * support/Util/SDCCerr.h
8341 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8343 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
8344 * src/SDCCicode.c (operandOperation): rewritten some ops
8345 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8346 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8348 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8349 be re-activated by defining REDUCE_LITERALS)
8350 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8351 unsigned, but are signed by default
8352 * src/SDCCval.c (constVal): rearranged
8353 * src/SDCCval.c (valMod): preliminary fix
8354 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8396 constants are unsigned; added recognition of "u" flag for unsigned
8397 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8398 * src/SDCCval.c (valDiv, valMod): fixed signdness
8399 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8400 signedness of modulo, left and right shift

8859 * src/SDCCmain.c: linkOptions is changed to set *,
8860 added if/endif conditional macros to remove options help
8861 messages from optionsTable when a port is not configured, added
8862 support for the PIc16 port in the ports table, when executing
8863 the compiler with no port specified on command line, a default
8864 port is selected with the new macro DEFAULT_PORT which is
8865 defined in port.h, in setDefaultOptions() linkOptions is removed
8866 from initialization assignment, since now it is a set,
8867 parseCmdLine uses setParseWithComma for linkOptions, in
8868 linkEdit() linkOptions are accessed with new function indexSet()
8869 which returns the i'th item of a set variable. See SDCCset.c, in
8870 linkEdit() when calling buildCmdLine(), added linkOptions as
8871 last argument. Now users can pass arguments to gplink via the
8872 -Wl option, main() uses pic16glue() to glue up pic16 programs

8885 * src/pic16/main.c: __config directives are commented out to stop
8886 gpasm complaining and test the linkage with gplink, _linkCmd and
8887 _asmCmd changed to be more gplink and gpasm friendly
8888 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8889 produced an error when parsed, peep rule 12 is added to utilize
8890 movff, but it is commented out since the pCode does not support
8891 yet a command with 2 address arguments
8893 2003-05-18 <johan AT balder>
8895 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8922 2003-05-11 Borut Razem <borut.razem AT siol.net>
8924 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8925 the path of bin directory, so that PATH is the only env. variable, which has to be set
8926 in case of standard installation.
8927 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9954 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9956 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9958 * in \sdcc\as\mcs51\ changed these files in order to create an
9959 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9960 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9961 following files to include the previous two files: aslink.dsp,
9962 Makefile.aslink, Makefile.bcc, and Makefile.in.
9964 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9965 .adb instead of .cdb
9967 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9969 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9970 value from option --iram-size.
9972 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9974 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9977 2002-09-18 <wiml AT hhhh.org>
9979 * SDCClrange.h: exposed setFromRange() and setToRange()
9980 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9981 packRegsForAccUse() (bug 542397)
9982 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9983 multiple times and emitting the fetch operations more than once
9984 added aopGetUsesAcc() function to allow binary operators to
9985 fetch their operands in the correct order; made genMinus() emit
9986 compact code for X = LITERAL - Y
9988 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9989 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9990 sprintf() in line 1267.
9992 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9993 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9996 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9997 Changes to aslink (All the changes are marked with 'JCF'):
9999 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10002 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10003 area BSEG. Also moves, if possible, the DATA area down into the internal
10004 ram so more space is available.
10006 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10009 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10010 not bytes. Function summary() which creates a memory usage summary
10011 file with extension .mem. Reports of overlaping stack and small stack
10012 size. If the space for the stack is less than 16 bytes aslink trows a
10015 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10016 the 8051. Option 'y' for memory summary output file.
10018 Changes to sdcc (All the changes are marked with 'JCF'):
10020 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10022 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10023 overlaying area for it (uses RegBankUsed[4]).
10025 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10026 bank zero as used by default. By default aslink locates the stack
10027 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10028 the creation of the .mem file. Delegates the allocation of data area
10029 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10030 the begining of the stack area to aslink.
10032 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10033 glue() in SDCCglue.c creates an area for it.
10035 2002-09-03 Borut Razem <borut.razem AT siol.net>
10036 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10037 sdcc/src/pic/glue.c:
10038 introduced atexit() handler for teporay files removal in case of
10039 errors, assertions, ...
10041 2002-08-29 Borut Razem <borut.razem AT siol.net>
10042 * sdcc/support/cpp2/auto-host_vc_in.h:
10043 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10044 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10045 Maybe there is a similar problem with BORLANDC? It should be checked!
10047 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10048 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10049 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10050 was not executed, and the compiler (cl) launched a warning:
10051 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10053 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10054 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10056 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10057 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10059 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10060 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10061 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10062 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10063 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10064 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10065 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10066 - added Release configuration in VS projects
10067 - review of compiler an linker options
10068 - VC .exe files are generated in bin_vc directory, not to interfere
10069 with binaries generated from other projects (cygwin, mingw, bcc ...)
10071 * sdcc/src/yacc.dsp: added
10073 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10074 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10075 and insert the version number definitions from .version
10077 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10079 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10080 added - genarate auto-host.h using auto-host_vc_in.h as template
10083 removed from CVS, generated automatically
10085 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10086 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10088 2002-08-11 Borut Razem <borut.razem AT siol.net>
10089 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10091 2002-08-10 Borut Razem <borut.razem AT siol.net>
10092 * src/SDCCmain.c (main):
10093 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10094 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10095 The consequence was that some temporary files were not removed.
10098 unification of code in functions tempfilename() and tempfile():
10099 function tempnam() is defined in Visual Studio 6.0 and .NET
10101 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10103 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10104 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10105 - removed compiler command line option /WX: Treats all warnings as errors
10106 - update a list of source files, included into the project
10108 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10109 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10110 changed project type to Generic Project so that can be correcly converted to VS.NET project
10112 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10114 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10116 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10118 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10119 added return 0 statements after assert() to make compiler happy
10121 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10122 added newline in the def file to keep MSC compiler satisfied
10124 * sdcc/src/z80/gen.c:
10125 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10126 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10127 - solved MSC error in function aopDump()
10129 * sdcc_vc.h: define PREFIX as "\\sdcc"
10131 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10132 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10135 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10136 - Rewrote the register banking algorithm.
10137 - Added pCode live-range analysis to registers (for now, only non-used and
10138 singly-used registers optimized away)
10140 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10142 * 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.

10169 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10171 2002-03-28 Johan Knol <johan AT balder>
10173 * src/SDCCval.c: fixed bug #532436
10175 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10177 Added "char *Processor" field to the port structure.
10180 Added -p option. Allows port dependent processor to be specified.
10183 Initialized the new field char *Processor field to NULL in all ports
10186 Compiler generated registers for interrupt context saving
10187 were not getting allocated.
10189 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10192 Fixed left shift. Will promote the left side of a left shift
10193 if a) left shifting more than size of operand or b) when assigned
10194 to something size > size of left side

10304 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10306 * sdcc/src/SDCCloop.c:
10307 Previous fix was not good. basic blocks that have "break" or "return" are
10308 not really partof a loop , but live ranges used in these blocks should
10309 be live thru the entire loop, so set partOfLoop but don't add them to
10312 2002-02-21 <johan AT FRIJA>
10314 * src/SDCCcse.c: fixed bug #514308
10316 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
