91 Enabled VPATH feature: changed nearly all Makefiles (149 files).
92 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
94 One basic decision: e.g. src/clean.mk includes further files. In order
95 to make this work there are two solutions:
96 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
97 run configure on them. This way they can use
98 'include $(srcdir)/port-clean.mk'
99 - always include clean.mk by the Makefile at the same level. To avoid
100 that `make clean` tries to include and build Makefile.dep the
101 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
102 implemented, because now even `make uninstall` doesn't create
103 Makefile.in. clean.mk could be eliminated by pasting it in
106 * debugger/mcs51/Makefile.in: build own objects from library sources
107 (SLIB, SDCC) in current directory
109 * configure, configure.in: renamed --disable-device-lib-build in
110 --disable-device-lib; added --enable-doc, the required tools are
111 searched by configure; added result message; the toolchain for the
112 belonging ports are now only built, if the port is enabled.
114 * support/regression/*: all output is written in directory gen, because
115 the fwk and ports directories don't livet in the build tree using vpath
117 * doc/sdccman.lyx: renamed --disable-device-lib-build to
118 --disable-device-lib, added --enable-doc, added section VPATH
120 * sim/ucsim/configure.in,
121 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
122 z80 are enabled by default
124 2006-04-24 Raphael Neider <rneider AT web.de>
126 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
127 to config word, "pic14_"-prefixed some extern functions
128 (pic14_emitConfigWord): emit __config directive(s) if assignment to
129 config word has been found
130 * src/pic/device.h: added prototypes
131 * src/pic/pcode.c: added "pic14_"-prefix where needed
132 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
134 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

148 fixes #1469504 and #1474602,
149 (pCodeRegOptimizeRegUsage): fixed typo in comment

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

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

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

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

2802 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
2803 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
2804 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
2805 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
2806 always available in leading double underscore form. The C99 support is

2887 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2889 * device/lib/printf_large.c: removed inline assembly for portability and
2890 readability. Use printf_fast if speed or size are more important.
2891 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2892 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2894 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2896 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2897 prevent compiler warning
2899 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2901 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2902 moved to level 0 and declared as static. Also they are explicit
2903 placed in access bank. This was necessery because some times they
2904 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2905 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2906 optimizations. Currently only compare to unsigned char is implemented,
2907 * src/pic16/gen.c: added fReturnIdx array,
2908 * (struct resolvedIfx) is moved to gen.h and made public,
2909 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2910 * (aopForSym): added an optimization to directly store in stack of
2911 the operand of a SEND iCode,
2912 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2913 but as registers instead (AOP_REG) using the fReturnIdx array,
2914 * (pic16_freeAsmop): remove the freed register from the
2915 _G.sregsAlloc field,
2916 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2917 a compare of 'WREG',
2918 * (pic16_popGetTempRegCond): changed function prototype, now
2919 function takes also a bitVector argument v which holds the current
2920 set of registers that are allocated for stack access by aopForSym,
2921 registers allocated in aopForSym for accessing stack symbols are not
2922 any more part of the functions usedRegs field,
2923 * (genCall): some times aopOp is called for a stack variable to be
2924 send, aopForSym might perform the push, if this is true make sure
2925 that genCall doesn't push the variable twice by testing _G.resDirect,
2926 * (genFunction): changed testing for unspecified interrupt number
2927 from 256 to INTNO_UNSPEC,
2928 * modified selection scheme of frame pointer generation. Previously
2929 if function did use local registers a frame pointer was generated,
2930 now a frame pointer is generated only if function has arguments
2931 (that need PLUSW2 register access), or has stack arguments, or the
2932 compiler is not instructed to omit the frame pointer,
2933 * (genEndFunction): before restoring local registers that were saved
2934 in the function preamble, also restore the registers that *might*
2935 have been allocated for stack access,
2936 * (genRet): removed some old comments,
2937 * (genCmp, the active (RN's) version): added a call to the
2938 pic16_genCmp_special function to perform the compare with a more
2939 robust and optimized way,
2940 * (genInline): a feature has been added in inline code generation,
2941 which allows a wildcard variable substitution when writing inline
2942 assembly. Code is incomplete and experimental therefore undocumented,
2943 * (genCast): changed order of aopOp for result and right to allow
2944 aopForSym to directly load the result if possible,
2945 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2946 perform an optimized compare on some selected special occasions,
2947 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2948 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2949 generate an IVT any more,
2950 * src/pic16/main.c (pic16_optionsTable): added command line option
2952 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2953 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2955 * src/pic16/NOTES: Raphael Neider added in list of active developers
2956 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2957 jumptable_end to prevent bug #,
2958 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2959 inCond and outCond fields,
2960 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2961 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2962 turn off register spilling,
2963 * (packRegsForOneUse): synced with other ports' versions although it
2964 is not used currently,
2965 * (pic16_packRegisters): added an optimization while reading
2966 structure bitfields, some registers may be saved (malloc code is
2967 decreased by 80 bytes)
2969 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2971 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2972 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2973 this can be optimized more?
2975 2005-03-10 Raphael Neider <rneider AT web.de>
2977 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2978 genNearPointerGet): (hopefully) fixed access to bitfields via
2979 pointers (p->bitN = x; and x = p->bitN; failed)
2981 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
2983 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3022 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3024 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes

3613 Adding support for replacing ljmps with sjmps in jumptables
3614 generated for switch statements. For now you need to set the
3615 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3616 Now 4 algorithms for mcs51 jumptable generation are used:
3617 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3618 addresses loaded pc-relative for up to 112 cases and stack-pushing
3619 target addresses loaded with offset from dptr for up to 256 cases.

3649 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3651 * added libc directory. The current version of LibC contains string
3652 functions, ctype functions and macros and some functions of the
3653 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3654 be extensively tested in the future. Standard disclaimer here.
3655 Library is not automatically build yet. But one can build it by
3656 invoking 'make' inside the libc directory.

3667 * (pic16_storeForReturn): optimized return of 0,
3668 * (genCmp): experimental code for new genCmp which uses PIC18's
3669 special compare&skip instructions. Initial tests fail some times
3670 with variables grater than 1 byte in size, so new code is disabled,
3671 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3673 * (genCast): began a fix to optimize the casting of a bit to another
3674 bit, now assigning a bitfield to another bitfield will fail, sorry,
3675 * src/pic16/main.c: disabled the use of lr-support feature,
3676 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

3683 and 1 for banking instruction,
3684 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
3685 caused stop processing pCodes after a inline assembly block,
3686 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
3687 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
3688 registers when it shouldn't,
3689 * src/pic16/ralloc.c (allocReg): add preliminary support for
3690 supporting a limited set of temporary registers,
3692 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3694 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
3695 genDataPointerSet): ensure assignments always copy in MSB to LSB
3697 (loadRegFromAop): recognize CLRH optimization,
3698 (genFunction): optimize RECEIVE iCodes in reentrant functions
3700 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3702 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

6613 * src/SDCCast.c: added an additional type flow in decorateType() of
6614 opposite direction, see feature request #860006; it's enabled at runtime
6615 by setting the environment variable SDCC_NEWTYPEFLOW

6700 loaded with the linker search paths (-L arguments) and the libraries
6701 to be linked with the current source (-l arguments). Changes
6702 currently will affect only the pic16 port.
6703 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6704 include path the port specific paths and port specific libraries,
6705 * gplink command now contains the $3 argument,
6706 * src/pic16/device.h,
6707 * src/pic16/device.c,: structure PIC_device is made public and

6723 Documenting changes from previous commits.
6724 * configure.in (version 1.56),
6725 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6726 when generating output files to configure the pic16 library,
6727 but now I've commented it out, since gputils aren't installed in the
6728 SF compile farm, so library won't compile
6730 * device/lib/Makefile.in (version 1.56): initially I've added in
6731 target 'all' the prerequestive 'model-pic16' so it compiled the
6732 pic16 library, but now I've commented it out for the same reasons
6734 * added targets 'model-pic16' and 'objects-pic16' to compile the
6736 * added target 'port-specific-objects-pic16' to handle the
6737 generated libraries and copy them into the build/ directory
6738 * added target 'clean-intermediate-pic16' to clean intermediate
6739 files into pic16 directory
6740 * in target 'installdirs' added line to create directory pic16 in

7043 * added files genutils.c and genutils.h which contain gen*
7044 debugged and optimised functions extracted from gen.c
7046 * glue.c: added variable 'externs' which holds extern symbols,
7047 pic16emitRegularMap: is modified to properly handle relocatable
7048 symbols under the new scheme,
7049 pic16createInterruptVect: is modified
7050 pic16printPublics: is modified to emit 'global' assembler directives,
7051 added pic16_printExterns to print extern symbols,
7052 pic16glue: initializes stack/frame pointer in the beginning of
7053 the assembly output. Temporary hack, will be corrected later,
7054 because gplink yet does not support stack and SDCC does not
7055 yet support a type of crt0.o object to create the final binary.
7057 * Removed many lines that contain 8051 legacy code.
7058 * The code is finally placed under a 'code' directive.
7059 * Added port specific options.
7061 * _process_pragma: simplified since now we do not need *special*
7062 include file to define SFR registers. But a separate header
7063 will be needed. This will be developed later.
7064 * _pic16_parseOptions: added, parses port specific options:
7065 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7066 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7067 --preplace-udata-with=
7069 * _pic16_setDefaultOptions: modified to initialize section names,
7070 but hack is temporarly out of order since it needs improvement.
7071 * _pic16_genAssemblerPreamble: configuration words are emitted by
7072 their address instead of their name. This part is incomplete and
7073 supports only the 18Fxx2 devices. Other devices will emit an error
7074 during assembly since they do not contain the same set of config
7076 * _pic16_genIVT: is modified,
7078 * pcode.c: added definitions for some hardware registers that are needed
7080 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7081 All PCI entries are updated. Now LFSR is supported.
7082 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7083 * added pic16_newpCodeOpLit2 to support instructions with
7084 two literal arguments
7085 * pic16_pCode2str: corrected code that emits assembler instructions
7086 with two literal operands and those that have an access bit modifier
7087 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7088 this fixes a bug which caused some labels to be lost, when an
7089 assembler directive was added, i.e. banksel,
7090 * pic16_FixRegisterBanking: improved logic that causes the insertion
7092 * InlineFunction: functions that are called once, are not any more
7093 inlined. This can be a port option in the future,
7095 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7097 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7098 hold the corresponding uninitialized symbols,
7099 * pic16_allocProcessorRegister: registers have explicit marked the
7101 * pic16_allocInternalRegister: registers are explicit marked as
7103 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7104 processing list, so bit registers were lost,
7107 * ralloc.h: added field 'accessBank' and original symbol operand
7108 in register definition,
7109 * removed the field isMapped from register definition,
7111 ** Several functions have been removed from various sources:
7112 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7113 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7114 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7115 pic16_assignRelocatableRegisters
7117 ** others have been introduced:
7118 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7119 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7121 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7123 * support/scripts/inc2h.pl: changed definition of BIT_AT
7124 to emit 'sbit at' instead of 'bit at'. This was a request.
7126 PIC16 port related preliminary changes:
7127 * gen.c: prefixed function popRegFromString with
7128 pic16_ and all references to it corrected
7129 * pcode.c: all pic16_pc_* hardware registers prefixed
7130 with underscore (_),
7131 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7132 * ralloc.c: newReg(): when register is REG_SFR then
7133 set address to rIdx,
7134 pic16_allocProcessorRegister(): marks register wasUsed=0
7135 pic16_writeUsedRegs(): added a call to assign processor
7136 registers via pic16_assignFixedRegisters
7138 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7140 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7141 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7142 variables in unused register banks. Also the SSEG is placed
7143 wherever there is enough space for it, and IDATA can be anywhere
7144 in internal RAM. For now compile using -Wl-Y[stack_size].
7145 The mem file is different for this option as well, since it
7146 makes no sense of talking about DSEG lenght.
7148 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7150 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7151 in certain cases, e.g. when ROM assignment, patch provided
7152 from Albert den Haan.

7297 * src/mcs51/peephole.def,
7298 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

7393 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7395 * src/SDCCast.c (decorateType): disabled a transformation I added in
7396 revision 1.188 (access to fields of a structure at an absolute address);
7397 it breaks with bitfields, extern declarations, and gcse analysis.
7398 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7399 could be assigned through a pointer, so don't complain.
7400 * src/SDCCast.c (astErrors),
7402 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7502 2003-11-13 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7504 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
7505 uninitialized variables) for the mcs51. Set environment variable

8156 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8157 fetching of the pointer
8158 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8159 copied from genNearPointerSet()
8160 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8161 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8177 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8178 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8179 type for bits was changed. It resulted in bit variables becoming
8180 global, which is not permitted in PIC 14 assembly output.
8182 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8184 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8197 A few small changes that speed up the peephole optimizer.
8201 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8203 Try to make the peephole optimizer smarter by maintaining
8204 an association between the assembly source code and the
8205 iCodes that originated them. Put this information to use
8206 with a new peephole rule condition "notVolatile" so that
8207 the rules can be aggressive yet still safe.
8212 * src/mcs51/peeph.def
8214 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8218 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8219 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8220 if the left or right operand symbols have the accuse flag set.
8222 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8224 Changed the type of the result of the ! (NOT) operator to char;
8225 previously it returned the same type as the source. This allows
8226 us to eliminate all the genFloatNot functions (all of its target
8227 implementations were very buggy) since !float can use the same
8230 * src/SDCCicode.c (ast2iCode): ! returns char

8239 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8240 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8241 during interrupts. Ensure WSAVE is located at a shared bank address.
8242 2. Fixed page selection in some places
8243 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8244 the registers name strings.
8245 4. Fixed "signed / unsigned compare" compiler warnings.
8246 5. The PIC port manages its own allocation of the general purpose
8247 registers, but makes no attempt to reuse them. As a result when
8248 compiling it soon runs out of general purpose registers. Some
8249 additional code was added to the files pcode.c and device.c to walk
8250 through the function call tree and rename the registers so that they
8260 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8261 genPlus() & genMinus() when the result is the same as left or right

8267 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8269 Made bitfield a distinct type from bit so that bitfields
8270 convert as per ANSI C and bits retain their traditional
8271 boolean style behaviour. Implemented bitfield support in
8279 * src/ds390/gen.c: bit v bitfield split
8280 * src/z80/gen.c: New support for bitfields
8281 * support/regression/tests/bitfields.c: reenabled z80,
8284 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8286 Rules 246.x, 247.x relate to bitfields, the others speed up
8287 access to xdata mapped I/O devices.
8289 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8291 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8293 Cleaned up genPackBits and genUnpackBits and added two helper
8294 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8295 for literal assignments in genPackBits (thanks to Frieder for
8301 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8303 Fixed bug #748310 (pointer to function type mishandled when the
8304 function name is omitted). Also fixed a SIGSEGV when a function
8305 attribute (reentrant, etc) is used on a non-function or on a
8306 function but misplaced before the parameter list.
8308 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8310 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8311 * support/Util/SDCCerr.h,
8312 * support/Util/SDCCerr.c: Added func attr misuse error msg

8333 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8335 Made the constant following the "interrupt" keyword optional. If
8336 omitted, the function will not automatically be given an entry
8337 in the interrupt vector table (similar to #pragma NOIV, but
8338 less syntacticly kludgy). The interrupt number is also now
8339 range checked. Also fixed a bug in the high order bit example

8353 * src/SDCCicode.c (operandOperation): rewritten some ops
8354 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8355 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8357 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8358 be re-activated by defining REDUCE_LITERALS)
8359 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8360 unsigned, but are signed by default
8361 * src/SDCCval.c (constVal): rearranged
8362 * src/SDCCval.c (valMod): preliminary fix
8363 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8405 constants are unsigned; added recognition of "u" flag for unsigned
8406 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8407 * src/SDCCval.c (valDiv, valMod): fixed signdness
8408 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8409 signedness of modulo, left and right shift

8868 * src/SDCCmain.c: linkOptions is changed to set *,
8869 added if/endif conditional macros to remove options help
8870 messages from optionsTable when a port is not configured, added
8871 support for the PIc16 port in the ports table, when executing
8872 the compiler with no port specified on command line, a default
8873 port is selected with the new macro DEFAULT_PORT which is
8874 defined in port.h, in setDefaultOptions() linkOptions is removed
8875 from initialization assignment, since now it is a set,
8876 parseCmdLine uses setParseWithComma for linkOptions, in
8877 linkEdit() linkOptions are accessed with new function indexSet()
8878 which returns the i'th item of a set variable. See SDCCset.c, in
8879 linkEdit() when calling buildCmdLine(), added linkOptions as
8880 last argument. Now users can pass arguments to gplink via the
8881 -Wl option, main() uses pic16glue() to glue up pic16 programs

8894 * src/pic16/main.c: __config directives are commented out to stop
8895 gpasm complaining and test the linkage with gplink, _linkCmd and
8896 _asmCmd changed to be more gplink and gpasm friendly
8897 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8898 produced an error when parsed, peep rule 12 is added to utilize
8899 movff, but it is commented out since the pCode does not support
8900 yet a command with 2 address arguments
8902 2003-05-18 <johan AT balder>
8904 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8931 2003-05-11 Borut Razem <borut.razem AT siol.net>
8933 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
8934 the path of bin directory, so that PATH is the only env. variable, which has to be set
8935 in case of standard installation.
8936 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

9963 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9965 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9967 * in \sdcc\as\mcs51\ changed these files in order to create an
9968 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9969 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9970 following files to include the previous two files: aslink.dsp,
9971 Makefile.aslink, Makefile.bcc, and Makefile.in.
9973 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9974 .adb instead of .cdb
9976 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9978 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9979 value from option --iram-size.
9981 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9983 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9986 2002-09-18 <wiml AT hhhh.org>
9988 * SDCClrange.h: exposed setFromRange() and setToRange()
9989 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9990 packRegsForAccUse() (bug 542397)
9991 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9992 multiple times and emitting the fetch operations more than once
9993 added aopGetUsesAcc() function to allow binary operators to
9994 fetch their operands in the correct order; made genMinus() emit
9995 compact code for X = LITERAL - Y
9997 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9998 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9999 sprintf() in line 1267.
10001 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10002 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10005 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10006 Changes to aslink (All the changes are marked with 'JCF'):
10008 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10011 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10012 area BSEG. Also moves, if possible, the DATA area down into the internal
10013 ram so more space is available.
10015 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10018 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10019 not bytes. Function summary() which creates a memory usage summary
10020 file with extension .mem. Reports of overlaping stack and small stack
10021 size. If the space for the stack is less than 16 bytes aslink trows a
10024 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10025 the 8051. Option 'y' for memory summary output file.
10027 Changes to sdcc (All the changes are marked with 'JCF'):
10029 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10031 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10032 overlaying area for it (uses RegBankUsed[4]).
10034 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10035 bank zero as used by default. By default aslink locates the stack
10036 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10037 the creation of the .mem file. Delegates the allocation of data area
10038 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10039 the begining of the stack area to aslink.
10041 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10042 glue() in SDCCglue.c creates an area for it.
10044 2002-09-03 Borut Razem <borut.razem AT siol.net>
10045 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10046 sdcc/src/pic/glue.c:
10047 introduced atexit() handler for teporay files removal in case of
10048 errors, assertions, ...
10050 2002-08-29 Borut Razem <borut.razem AT siol.net>
10051 * sdcc/support/cpp2/auto-host_vc_in.h:
10052 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10053 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10054 Maybe there is a similar problem with BORLANDC? It should be checked!
10056 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10057 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10058 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10059 was not executed, and the compiler (cl) launched a warning:
10060 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10062 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10063 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10065 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10066 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10068 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10069 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10070 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10071 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10072 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10073 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10074 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10075 - added Release configuration in VS projects
10076 - review of compiler an linker options
10077 - VC .exe files are generated in bin_vc directory, not to interfere
10078 with binaries generated from other projects (cygwin, mingw, bcc ...)
10080 * sdcc/src/yacc.dsp: added
10082 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10083 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10084 and insert the version number definitions from .version
10086 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10088 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10089 added - genarate auto-host.h using auto-host_vc_in.h as template
10092 removed from CVS, generated automatically
10094 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10095 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10097 2002-08-11 Borut Razem <borut.razem AT siol.net>
10098 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10100 2002-08-10 Borut Razem <borut.razem AT siol.net>
10101 * src/SDCCmain.c (main):
10102 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10103 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10104 The consequence was that some temporary files were not removed.
10107 unification of code in functions tempfilename() and tempfile():
10108 function tempnam() is defined in Visual Studio 6.0 and .NET
10110 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10112 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10113 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10114 - removed compiler command line option /WX: Treats all warnings as errors
10115 - update a list of source files, included into the project
10117 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10118 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10119 changed project type to Generic Project so that can be correcly converted to VS.NET project
10121 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10123 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10125 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10127 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10128 added return 0 statements after assert() to make compiler happy
10130 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10131 added newline in the def file to keep MSC compiler satisfied
10133 * sdcc/src/z80/gen.c:
10134 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10135 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10136 - solved MSC error in function aopDump()
10138 * sdcc_vc.h: define PREFIX as "\\sdcc"
10140 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10141 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10144 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10145 - Rewrote the register banking algorithm.
10146 - Added pCode live-range analysis to registers (for now, only non-used and
10147 singly-used registers optimized away)
10149 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10151 * 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.

10176 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10178 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10180 2002-03-28 Johan Knol <johan AT balder>
10182 * src/SDCCval.c: fixed bug #532436
10184 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10186 Added "char *Processor" field to the port structure.
10189 Added -p option. Allows port dependent processor to be specified.
10192 Initialized the new field char *Processor field to NULL in all ports
10195 Compiler generated registers for interrupt context saving
10196 were not getting allocated.
10198 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10201 Fixed left shift. Will promote the left side of a left shift
10202 if a) left shifting more than size of operand or b) when assigned
10203 to something size > size of left side
10205 2002-03-14 Scott Dattalo <scott AT dattalo.com>

10209 analysis is restructured. ...
10211 * src/pic/device.h:
10214 * src/pic/device.c:
10215 Added. device.c is a PIC port hack to accomodate variations
10218 2002-03-13 Michael Hope <michaelh AT vroom>
10220 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10222 2002-03-04 johanknol <johanknol AT manik>
10224 * /src/SDCCval.c: fixed

10313 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10315 * sdcc/src/SDCCloop.c:
10316 Previous fix was not good. basic blocks that have "break" or "return" are
10317 not really partof a loop , but live ranges used in these blocks should
10318 be live thru the entire loop, so set partOfLoop but don't add them to
10321 2002-02-21 <johan AT FRIJA>
10323 * src/SDCCcse.c: fixed bug #514308
10325 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10328 Fixed BUG #519583. If a conditional block ended in a return/break
10329 statement inside a loop, it was not being considered part of the loop.
10331 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10333 2002-02-10 Karl Bongers <karl AT turbobit.com>
