73 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
75 Enabled VPATH feature: changed nearly all Makefiles (149 files).
76 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
78 One basic decision: e.g. src/clean.mk includes further files. In order
79 to make this work there are two solutions:
80 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
81 run configure on them. This way they can use
82 'include $(srcdir)/port-clean.mk'
83 - always include clean.mk by the Makefile at the same level. To avoid
84 that `make clean` tries to include and build Makefile.dep the
85 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
86 implemented, because now even `make uninstall` doesn't create
87 Makefile.in. clean.mk could be eliminated by pasting it in
90 * debugger/mcs51/Makefile.in: build own objects from library sources
91 (SLIB, SDCC) in current directory
93 * configure, configure.in: renamed --disable-device-lib-build in
94 --disable-device-lib; added --enable-doc, the required tools are
95 searched by configure; added result message; the toolchain for the
96 belonging ports are now only built, if the port is enabled.
98 * support/regression/*: all output is written in directory gen, because
99 the fwk and ports directories don't livet in the build tree using vpath
101 * doc/sdccman.lyx: renamed --disable-device-lib-build to
102 --disable-device-lib, added --enable-doc, added section VPATH
104 * sim/ucsim/configure.in,
105 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
106 z80 are enabled by default
108 2006-04-24 Raphael Neider <rneider AT web.de>
110 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
111 to config word, "pic14_"-prefixed some extern functions
112 (pic14_emitConfigWord): emit __config directive(s) if assignment to
113 config word has been found
114 * src/pic/device.h: added prototypes
115 * src/pic/pcode.c: added "pic14_"-prefix where needed

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

484 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
486 * src/pic16/gen.c (genPcall): fixed bug #1443644
487 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
488 which dumps before the function entry point a data byte which represents
489 the number of the local variables used by the specified function, added
490 'xinst' for initial support for Extended Instruction Support,
491 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
492 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
493 port->fun_prefix anymore (may change later),
494 (genFunction, genEndFunction): do not store/restore local registers for
495 _main (this should take care the --main-return command line option in
497 (genOr): removed some legacy pic-port instructions,
498 * src/pic16/genarith.c (genAddLit): re-enabled old code because
499 performing operations with SFR's causes data to be written more than

501 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
503 * src/pic16/main.c (_process_pragma): stack bound checking did not take

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

2786 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2787 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2788 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2789 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2790 always available in leading double underscore form. The C99 support is
2791 mostly missing, but it's a start.
2792 * support/regression/tests/bug-227710.c: fixed nonconforming use of
2793 reserved identifier "__data".

2871 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2873 * device/lib/printf_large.c: removed inline assembly for portability and
2874 readability. Use printf_fast if speed or size are more important.
2875 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2876 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2878 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2880 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2881 prevent compiler warning
2883 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2885 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2886 moved to level 0 and declared as static. Also they are explicit
2887 placed in access bank. This was necessery because some times they
2888 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2889 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2890 optimizations. Currently only compare to unsigned char is implemented,
2891 * src/pic16/gen.c: added fReturnIdx array,
2892 * (struct resolvedIfx) is moved to gen.h and made public,
2893 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2894 * (aopForSym): added an optimization to directly store in stack of
2895 the operand of a SEND iCode,
2896 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2897 but as registers instead (AOP_REG) using the fReturnIdx array,
2898 * (pic16_freeAsmop): remove the freed register from the
2899 _G.sregsAlloc field,
2900 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2901 a compare of 'WREG',
2902 * (pic16_popGetTempRegCond): changed function prototype, now
2903 function takes also a bitVector argument v which holds the current
2904 set of registers that are allocated for stack access by aopForSym,
2905 registers allocated in aopForSym for accessing stack symbols are not
2906 any more part of the functions usedRegs field,
2907 * (genCall): some times aopOp is called for a stack variable to be
2908 send, aopForSym might perform the push, if this is true make sure
2909 that genCall doesn't push the variable twice by testing _G.resDirect,
2910 * (genFunction): changed testing for unspecified interrupt number
2911 from 256 to INTNO_UNSPEC,
2912 * modified selection scheme of frame pointer generation. Previously
2913 if function did use local registers a frame pointer was generated,
2914 now a frame pointer is generated only if function has arguments
2915 (that need PLUSW2 register access), or has stack arguments, or the
2916 compiler is not instructed to omit the frame pointer,
2917 * (genEndFunction): before restoring local registers that were saved
2918 in the function preamble, also restore the registers that *might*
2919 have been allocated for stack access,
2920 * (genRet): removed some old comments,
2921 * (genCmp, the active (RN's) version): added a call to the
2922 pic16_genCmp_special function to perform the compare with a more
2923 robust and optimized way,
2924 * (genInline): a feature has been added in inline code generation,
2925 which allows a wildcard variable substitution when writing inline
2926 assembly. Code is incomplete and experimental therefore undocumented,
2927 * (genCast): changed order of aopOp for result and right to allow
2928 aopForSym to directly load the result if possible,
2929 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2930 perform an optimized compare on some selected special occasions,
2931 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2932 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2933 generate an IVT any more,
2934 * src/pic16/main.c (pic16_optionsTable): added command line option
2936 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2937 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2939 * src/pic16/NOTES: Raphael Neider added in list of active developers
2940 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2941 jumptable_end to prevent bug #,
2942 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2943 inCond and outCond fields,
2944 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2945 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2946 turn off register spilling,
2947 * (packRegsForOneUse): synced with other ports' versions although it
2948 is not used currently,
2949 * (pic16_packRegisters): added an optimization while reading
2950 structure bitfields, some registers may be saved (malloc code is
2951 decreased by 80 bytes)
2953 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2955 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2956 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2957 this can be optimized more?
2959 2005-03-10 Raphael Neider <rneider AT web.de>
2961 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2962 genNearPointerGet): (hopefully) fixed access to bitfields via
2963 pointers (p->bitN = x; and x = p->bitN; failed)
2965 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3008 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3009 to keep the correct label reference count when adding/removing references
3010 to labels. A peephole file using this is appended to patch #1144962.
3012 2005-02-14 Raphael Neider <rneider AT web.de>

3597 Adding support for replacing ljmps with sjmps in jumptables
3598 generated for switch statements. For now you need to set the
3599 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3600 Now 4 algorithms for mcs51 jumptable generation are used:
3601 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3602 addresses loaded pc-relative for up to 112 cases and stack-pushing
3603 target addresses loaded with offset from dptr for up to 256 cases.

3633 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3635 * added libc directory. The current version of LibC contains string
3636 functions, ctype functions and macros and some functions of the
3637 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3638 be extensively tested in the future. Standard disclaimer here.
3639 Library is not automatically build yet. But one can build it by
3640 invoking 'make' inside the libc directory.

3651 * (pic16_storeForReturn): optimized return of 0,
3652 * (genCmp): experimental code for new genCmp which uses PIC18's
3653 special compare&skip instructions. Initial tests fail some times
3654 with variables grater than 1 byte in size, so new code is disabled,
3655 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3657 * (genCast): began a fix to optimize the casting of a bit to another
3658 bit, now assigning a bitfield to another bitfield will fail, sorry,
3659 * src/pic16/main.c: disabled the use of lr-support feature,
3660 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3667 and 1 for banking instruction,
3668 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3669 caused stop processing pCodes after a inline assembly block,
3670 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

3672 registers when it shouldn't,
3673 * src/pic16/ralloc.c (allocReg): add preliminary support for
3674 supporting a limited set of temporary registers,
3676 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3678 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

3682 (genFunction): optimize RECEIVE iCodes in reentrant functions
3684 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6595 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
6597 * src/SDCCast.c: added an additional type flow in decorateType() of
6598 opposite direction, see feature request #860006; it's enabled at runtime
6599 by setting the environment variable SDCC_NEWTYPEFLOW
6600 * src/SDCCast.h: changed prototype of decorateType()
6601 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()

6681 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6683 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6684 loaded with the linker search paths (-L arguments) and the libraries
6685 to be linked with the current source (-l arguments). Changes
6686 currently will affect only the pic16 port.
6687 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6688 include path the port specific paths and port specific libraries,
6689 * gplink command now contains the $3 argument,
6690 * src/pic16/device.h,
6691 * src/pic16/device.c,: structure PIC_device is made public and
6692 renamed to PIC16_device, the same for variable Pics which is renamed

6707 Documenting changes from previous commits.
6708 * configure.in (version 1.56),
6709 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6710 when generating output files to configure the pic16 library,
6711 but now I've commented it out, since gputils aren't installed in the
6712 SF compile farm, so library won't compile
6714 * device/lib/Makefile.in (version 1.56): initially I've added in
6715 target 'all' the prerequestive 'model-pic16' so it compiled the
6716 pic16 library, but now I've commented it out for the same reasons
6718 * added targets 'model-pic16' and 'objects-pic16' to compile the
6720 * added target 'port-specific-objects-pic16' to handle the
6721 generated libraries and copy them into the build/ directory
6722 * added target 'clean-intermediate-pic16' to clean intermediate
6723 files into pic16 directory
6724 * in target 'installdirs' added line to create directory pic16 in

7037 the assembly output. Temporary hack, will be corrected later,
7038 because gplink yet does not support stack and SDCC does not
7039 yet support a type of crt0.o object to create the final binary.
7041 * Removed many lines that contain 8051 legacy code.
7042 * The code is finally placed under a 'code' directive.
7043 * Added port specific options.
7045 * _process_pragma: simplified since now we do not need *special*
7046 include file to define SFR registers. But a separate header
7047 will be needed. This will be developed later.
7048 * _pic16_parseOptions: added, parses port specific options:
7049 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7050 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7051 --preplace-udata-with=
7053 * _pic16_setDefaultOptions: modified to initialize section names,
7054 but hack is temporarly out of order since it needs improvement.
7055 * _pic16_genAssemblerPreamble: configuration words are emitted by
7056 their address instead of their name. This part is incomplete and
7057 supports only the 18Fxx2 devices. Other devices will emit an error
7058 during assembly since they do not contain the same set of config
7060 * _pic16_genIVT: is modified,
7062 * pcode.c: added definitions for some hardware registers that are needed
7064 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7065 All PCI entries are updated. Now LFSR is supported.
7066 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7067 * added pic16_newpCodeOpLit2 to support instructions with
7068 two literal arguments
7069 * pic16_pCode2str: corrected code that emits assembler instructions
7070 with two literal operands and those that have an access bit modifier
7071 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7072 this fixes a bug which caused some labels to be lost, when an
7073 assembler directive was added, i.e. banksel,
7074 * pic16_FixRegisterBanking: improved logic that causes the insertion
7076 * InlineFunction: functions that are called once, are not any more
7077 inlined. This can be a port option in the future,
7079 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7081 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7082 hold the corresponding uninitialized symbols,
7083 * pic16_allocProcessorRegister: registers have explicit marked the
7085 * pic16_allocInternalRegister: registers are explicit marked as
7087 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7088 processing list, so bit registers were lost,
7091 * ralloc.h: added field 'accessBank' and original symbol operand
7092 in register definition,
7093 * removed the field isMapped from register definition,
7095 ** Several functions have been removed from various sources:
7096 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7097 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7098 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7099 pic16_assignRelocatableRegisters
7101 ** others have been introduced:
7102 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7103 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7105 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7107 * support/scripts/inc2h.pl: changed definition of BIT_AT
7108 to emit 'sbit at' instead of 'bit at'. This was a request.
7110 PIC16 port related preliminary changes:
7111 * gen.c: prefixed function popRegFromString with
7112 pic16_ and all references to it corrected
7113 * pcode.c: all pic16_pc_* hardware registers prefixed
7114 with underscore (_),
7115 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7116 * ralloc.c: newReg(): when register is REG_SFR then
7117 set address to rIdx,
7118 pic16_allocProcessorRegister(): marks register wasUsed=0
7119 pic16_writeUsedRegs(): added a call to assign processor
7120 registers via pic16_assignFixedRegisters
7122 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7124 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7125 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7126 variables in unused register banks. Also the SSEG is placed
7127 wherever there is enough space for it, and IDATA can be anywhere
7128 in internal RAM. For now compile using -Wl-Y[stack_size].
7129 The mem file is different for this option as well, since it
7130 makes no sense of talking about DSEG lenght.
7132 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7134 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7135 in certain cases, e.g. when ROM assignment, patch provided
7136 from Albert den Haan.

7379 * src/SDCCast.c (decorateType): disabled a transformation I added in
7380 revision 1.188 (access to fields of a structure at an absolute address);
7381 it breaks with bitfields, extern declarations, and gcse analysis.
7382 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7383 could be assigned through a pointer, so don't complain.
7384 * src/SDCCast.c (astErrors),
7386 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7488 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
7489 uninitialized variables) for the mcs51. Set environment variable

7491 xdata initialization slightly shorter
7493 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8023 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8024 support for standard C idiom of memory mapped variables; for
8025 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8026 to xdata int at 0x1234 tempvar = 1.

8044 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8046 Fixed bug #621531 (const & volatile confusion in the type chain).
8047 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8048 refer to the const or volatile state of the pointer itself.

8140 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8141 fetching of the pointer
8142 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8143 copied from genNearPointerSet()
8144 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8145 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8159 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8161 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8162 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8163 type for bits was changed. It resulted in bit variables becoming
8164 global, which is not permitted in PIC 14 assembly output.
8166 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8168 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8181 A few small changes that speed up the peephole optimizer.
8185 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8187 Try to make the peephole optimizer smarter by maintaining
8188 an association between the assembly source code and the
8189 iCodes that originated them. Put this information to use
8190 with a new peephole rule condition "notVolatile" so that
8191 the rules can be aggressive yet still safe.
8196 * src/mcs51/peeph.def
8198 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8202 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8203 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8204 if the left or right operand symbols have the accuse flag set.
8206 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8208 Changed the type of the result of the ! (NOT) operator to char;
8209 previously it returned the same type as the source. This allows
8210 us to eliminate all the genFloatNot functions (all of its target
8211 implementations were very buggy) since !float can use the same
8214 * src/SDCCicode.c (ast2iCode): ! returns char

8223 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8224 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8225 during interrupts. Ensure WSAVE is located at a shared bank address.
8226 2. Fixed page selection in some places
8227 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8228 the registers name strings.
8229 4. Fixed "signed / unsigned compare" compiler warnings.
8230 5. The PIC port manages its own allocation of the general purpose
8231 registers, but makes no attempt to reuse them. As a result when
8232 compiling it soon runs out of general purpose registers. Some
8233 additional code was added to the files pcode.c and device.c to walk
8234 through the function call tree and rename the registers so that they
8244 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8245 genPlus() & genMinus() when the result is the same as left or right

8251 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8253 Made bitfield a distinct type from bit so that bitfields
8254 convert as per ANSI C and bits retain their traditional
8255 boolean style behaviour. Implemented bitfield support in
8263 * src/ds390/gen.c: bit v bitfield split
8264 * src/z80/gen.c: New support for bitfields
8265 * support/regression/tests/bitfields.c: reenabled z80,
8268 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8270 Rules 246.x, 247.x relate to bitfields, the others speed up
8271 access to xdata mapped I/O devices.
8273 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8275 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8277 Cleaned up genPackBits and genUnpackBits and added two helper
8278 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8279 for literal assignments in genPackBits (thanks to Frieder for
8285 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8287 Fixed bug #748310 (pointer to function type mishandled when the
8288 function name is omitted). Also fixed a SIGSEGV when a function
8289 attribute (reentrant, etc) is used on a non-function or on a
8290 function but misplaced before the parameter list.
8292 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8294 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8295 * support/Util/SDCCerr.h,
8296 * support/Util/SDCCerr.c: Added func attr misuse error msg

8317 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8319 Made the constant following the "interrupt" keyword optional. If
8320 omitted, the function will not automatically be given an entry
8321 in the interrupt vector table (similar to #pragma NOIV, but
8322 less syntacticly kludgy). The interrupt number is also now
8323 range checked. Also fixed a bug in the high order bit example

8337 * src/SDCCicode.c (operandOperation): rewritten some ops
8338 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8339 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8341 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8342 be re-activated by defining REDUCE_LITERALS)
8343 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8344 unsigned, but are signed by default
8345 * src/SDCCval.c (constVal): rearranged
8346 * src/SDCCval.c (valMod): preliminary fix
8347 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8389 constants are unsigned; added recognition of "u" flag for unsigned
8390 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8391 * src/SDCCval.c (valDiv, valMod): fixed signdness
8392 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8393 signedness of modulo, left and right shift

8852 * src/SDCCmain.c: linkOptions is changed to set *,
8853 added if/endif conditional macros to remove options help
8854 messages from optionsTable when a port is not configured, added
8855 support for the PIc16 port in the ports table, when executing
8856 the compiler with no port specified on command line, a default
8857 port is selected with the new macro DEFAULT_PORT which is
8858 defined in port.h, in setDefaultOptions() linkOptions is removed
8859 from initialization assignment, since now it is a set,
8860 parseCmdLine uses setParseWithComma for linkOptions, in
8861 linkEdit() linkOptions are accessed with new function indexSet()
8862 which returns the i'th item of a set variable. See SDCCset.c, in
8863 linkEdit() when calling buildCmdLine(), added linkOptions as
8864 last argument. Now users can pass arguments to gplink via the
8865 -Wl option, main() uses pic16glue() to glue up pic16 programs

8878 * src/pic16/main.c: __config directives are commented out to stop
8879 gpasm complaining and test the linkage with gplink, _linkCmd and
8880 _asmCmd changed to be more gplink and gpasm friendly
8881 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8882 produced an error when parsed, peep rule 12 is added to utilize
8883 movff, but it is commented out since the pCode does not support
8884 yet a command with 2 address arguments
8886 2003-05-18 <johan AT balder>
8888 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8915 2003-05-11 Borut Razem <borut.razem AT siol.net>
8917 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8918 the path of bin directory, so that PATH is the only env. variable, which has to be set
8919 in case of standard installation.

9954 following files to include the previous two files: aslink.dsp,
9955 Makefile.aslink, Makefile.bcc, and Makefile.in.
9957 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9958 .adb instead of .cdb
9960 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9962 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9963 value from option --iram-size.
9965 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9967 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9970 2002-09-18 <wiml AT hhhh.org>
9972 * SDCClrange.h: exposed setFromRange() and setToRange()
9973 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9974 packRegsForAccUse() (bug 542397)
9975 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9976 multiple times and emitting the fetch operations more than once
9977 added aopGetUsesAcc() function to allow binary operators to
9978 fetch their operands in the correct order; made genMinus() emit
9979 compact code for X = LITERAL - Y
9981 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9982 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9983 sprintf() in line 1267.
9985 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9986 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9989 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9990 Changes to aslink (All the changes are marked with 'JCF'):
9992 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9995 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9996 area BSEG. Also moves, if possible, the DATA area down into the internal
9997 ram so more space is available.
9999 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10002 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10003 not bytes. Function summary() which creates a memory usage summary
10004 file with extension .mem. Reports of overlaping stack and small stack
10005 size. If the space for the stack is less than 16 bytes aslink trows a
10008 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10009 the 8051. Option 'y' for memory summary output file.
10011 Changes to sdcc (All the changes are marked with 'JCF'):
10013 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10015 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10016 overlaying area for it (uses RegBankUsed[4]).
10018 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10019 bank zero as used by default. By default aslink locates the stack
10020 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10021 the creation of the .mem file. Delegates the allocation of data area
10022 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10023 the begining of the stack area to aslink.
10025 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10026 glue() in SDCCglue.c creates an area for it.
10028 2002-09-03 Borut Razem <borut.razem AT siol.net>
10029 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10030 sdcc/src/pic/glue.c:
10031 introduced atexit() handler for teporay files removal in case of
10032 errors, assertions, ...
10034 2002-08-29 Borut Razem <borut.razem AT siol.net>
10035 * sdcc/support/cpp2/auto-host_vc_in.h:
10036 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10037 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10038 Maybe there is a similar problem with BORLANDC? It should be checked!
10040 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10041 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10042 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10043 was not executed, and the compiler (cl) launched a warning:
10044 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10046 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10047 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10049 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10050 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10052 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10053 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10054 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10055 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10056 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10057 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10058 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10059 - added Release configuration in VS projects
10060 - review of compiler an linker options
10061 - VC .exe files are generated in bin_vc directory, not to interfere
10062 with binaries generated from other projects (cygwin, mingw, bcc ...)
10064 * sdcc/src/yacc.dsp: added
10066 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10067 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10068 and insert the version number definitions from .version
10070 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10072 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10073 added - genarate auto-host.h using auto-host_vc_in.h as template
10076 removed from CVS, generated automatically
10078 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10079 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10081 2002-08-11 Borut Razem <borut.razem AT siol.net>
10082 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10084 2002-08-10 Borut Razem <borut.razem AT siol.net>
10085 * src/SDCCmain.c (main):
10086 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10087 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10088 The consequence was that some temporary files were not removed.
10091 unification of code in functions tempfilename() and tempfile():
10092 function tempnam() is defined in Visual Studio 6.0 and .NET
10094 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10096 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10097 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10098 - removed compiler command line option /WX: Treats all warnings as errors
10099 - update a list of source files, included into the project
10101 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10102 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10103 changed project type to Generic Project so that can be correcly converted to VS.NET project
10105 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10107 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10109 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10111 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10112 added return 0 statements after assert() to make compiler happy
10114 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10115 added newline in the def file to keep MSC compiler satisfied
10117 * sdcc/src/z80/gen.c:
10118 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10119 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10120 - solved MSC error in function aopDump()
10122 * sdcc_vc.h: define PREFIX as "\\sdcc"
10124 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10125 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10162 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10164 2002-03-28 Johan Knol <johan AT balder>
10166 * src/SDCCval.c: fixed bug #532436
10168 2002-03-14 Scott Dattalo <scott AT dattalo.com>

10173 Added -p option. Allows port dependent processor to be specified.
10176 Initialized the new field char *Processor field to NULL in all ports
10179 Compiler generated registers for interrupt context saving
10180 were not getting allocated.
10182 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10185 Fixed left shift. Will promote the left side of a left shift
10186 if a) left shifting more than size of operand or b) when assigned
10187 to something size > size of left side

10297 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10299 * sdcc/src/SDCCloop.c:
10300 Previous fix was not good. basic blocks that have "break" or "return" are
10301 not really partof a loop , but live ranges used in these blocks should
10302 be live thru the entire loop, so set partOfLoop but don't add them to
10305 2002-02-21 <johan AT FRIJA>
10307 * src/SDCCcse.c: fixed bug #514308
10309 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
