304 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
306 Enabled VPATH feature: changed nearly all Makefiles (149 files).
307 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
309 One basic decision: e.g. src/clean.mk includes further files. In order
310 to make this work there are two solutions:
311 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
312 run configure on them. This way they can use
313 'include $(srcdir)/port-clean.mk'
314 - always include clean.mk by the Makefile at the same level. To avoid
315 that `make clean` tries to include and build Makefile.dep the
316 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
317 implemented, because now even `make uninstall` doesn't create
318 Makefile.in. clean.mk could be eliminated by pasting it in
321 * debugger/mcs51/Makefile.in: build own objects from library sources
322 (SLIB, SDCC) in current directory
324 * configure, configure.in: renamed --disable-device-lib-build in
325 --disable-device-lib; added --enable-doc, the required tools are
326 searched by configure; added result message; the toolchain for the
327 belonging ports are now only built, if the port is enabled.
329 * support/regression/*: all output is written in directory gen, because
330 the fwk and ports directories don't livet in the build tree using vpath
332 * doc/sdccman.lyx: renamed --disable-device-lib-build to
333 --disable-device-lib, added --enable-doc, added section VPATH
335 * sim/ucsim/configure.in,
336 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
337 z80 are enabled by default
339 2006-04-24 Raphael Neider <rneider AT web.de>
341 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
342 to config word, "pic14_"-prefixed some extern functions
343 (pic14_emitConfigWord): emit __config directive(s) if assignment to
344 config word has been found
345 * src/pic/device.h: added prototypes
346 * src/pic/pcode.c: added "pic14_"-prefix where needed
347 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
349 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
351 (pic14emitRegularMap): ignore config words,
352 (pic14createInterruptVect): moved generating __config directives away
353 (picglue): have __config directives emitted

363 fixes #1469504 and #1474602,
364 (pCodeRegOptimizeRegUsage): fixed typo in comment

627 the left operand is shorter than the result (c* = lit-c* + int),
629 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
632 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
634 * src/.version: increased version number to 2.5.5
635 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
636 linking is done manually in pic16 port's _linkEdit,
637 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
638 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
639 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
640 allocate asmop as AOP_ACC,
641 (aopForRemat): added parameter 'bool result' in function declaration,
642 (pic16_aopGet): return AOP_ACC when accessing WREG,

654 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
655 call to allocReg, not by manually allocating a new one,
656 (pic16_assignRegisters): now before going through the register
657 allocating functions mark all registers as free. This eliminates some
658 side effects resulting from peephole parser done earlier in the backbone

718 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
719 which dumps before the function entry point a data byte which represents
720 the number of the local variables used by the specified function, added
721 'xinst' for initial support for Extended Instruction Support,
722 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
723 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
724 port->fun_prefix anymore (may change later),
725 (genFunction, genEndFunction): do not store/restore local registers for
726 _main (this should take care the --main-return command line option in
728 (genOr): removed some legacy pic-port instructions,
729 * src/pic16/genarith.c (genAddLit): re-enabled old code because
730 performing operations with SFR's causes data to be written more than
731 once to each SFR. Perhaps SFRs should be handled in special cases...
732 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
734 * src/pic16/main.c (_process_pragma): stack bound checking did not take
735 into account for stack starting position,
736 (struct OPTIONS pic16_optionsTable): added command line argument
737 --extended or -y for Extended Instruction Support,
738 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
739 (deassignLRs): *** perhaps the most important change, old 'for' code
740 (commented out for reference), didn't account for some registers which
741 were left marked 'not free' after a pointer operation. The change
742 reduces register usage a lot in some cases

3072 2005-03-20 Borut Razem <borut.razem AT siol.net>
3074 * support/scripts/inc2h.pl: WIN32 port
3076 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3078 * device/lib/makefile.in: added abs.c and labs.c
3080 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3082 * device/include/stdint.h: added
3083 * device/lib/abs.c: added
3084 * device/lib/labs.c: added
3085 * device/include/stdlib.h: added abs() and labs() prototypes
3086 * device/lib/libsdcc.lib: added abs and labs
3087 * device/include/float.h,

3092 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3094 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed

3100 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3102 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3104 * device/lib/printf_large.c: removed inline assembly for portability and
3105 readability. Use printf_fast if speed or size are more important.
3106 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3107 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3109 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3111 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3112 prevent compiler warning
3114 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3116 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3117 moved to level 0 and declared as static. Also they are explicit
3118 placed in access bank. This was necessery because some times they
3119 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3120 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3121 optimizations. Currently only compare to unsigned char is implemented,
3122 * src/pic16/gen.c: added fReturnIdx array,
3123 * (struct resolvedIfx) is moved to gen.h and made public,
3124 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3125 * (aopForSym): added an optimization to directly store in stack of
3126 the operand of a SEND iCode,
3127 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3128 but as registers instead (AOP_REG) using the fReturnIdx array,
3129 * (pic16_freeAsmop): remove the freed register from the
3130 _G.sregsAlloc field,
3131 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3132 a compare of 'WREG',
3133 * (pic16_popGetTempRegCond): changed function prototype, now
3134 function takes also a bitVector argument v which holds the current
3135 set of registers that are allocated for stack access by aopForSym,
3136 registers allocated in aopForSym for accessing stack symbols are not
3137 any more part of the functions usedRegs field,
3138 * (genCall): some times aopOp is called for a stack variable to be
3139 send, aopForSym might perform the push, if this is true make sure
3140 that genCall doesn't push the variable twice by testing _G.resDirect,
3141 * (genFunction): changed testing for unspecified interrupt number
3142 from 256 to INTNO_UNSPEC,
3143 * modified selection scheme of frame pointer generation. Previously
3144 if function did use local registers a frame pointer was generated,
3145 now a frame pointer is generated only if function has arguments
3146 (that need PLUSW2 register access), or has stack arguments, or the
3147 compiler is not instructed to omit the frame pointer,
3148 * (genEndFunction): before restoring local registers that were saved
3149 in the function preamble, also restore the registers that *might*
3150 have been allocated for stack access,
3151 * (genRet): removed some old comments,
3152 * (genCmp, the active (RN's) version): added a call to the
3153 pic16_genCmp_special function to perform the compare with a more
3154 robust and optimized way,
3155 * (genInline): a feature has been added in inline code generation,
3156 which allows a wildcard variable substitution when writing inline
3157 assembly. Code is incomplete and experimental therefore undocumented,
3158 * (genCast): changed order of aopOp for result and right to allow
3159 aopForSym to directly load the result if possible,
3160 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3161 perform an optimized compare on some selected special occasions,
3162 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3163 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3164 generate an IVT any more,
3165 * src/pic16/main.c (pic16_optionsTable): added command line option
3167 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3168 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3170 * src/pic16/NOTES: Raphael Neider added in list of active developers
3171 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3172 jumptable_end to prevent bug #,
3173 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3174 inCond and outCond fields,
3175 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3176 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3177 turn off register spilling,
3178 * (packRegsForOneUse): synced with other ports' versions although it
3179 is not used currently,
3180 * (pic16_packRegisters): added an optimization while reading
3181 structure bitfields, some registers may be saved (malloc code is
3182 decreased by 80 bytes)
3184 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3186 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3187 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3188 this can be optimized more?
3190 2005-03-10 Raphael Neider <rneider AT web.de>
3192 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3193 genNearPointerGet): (hopefully) fixed access to bitfields via
3194 pointers (p->bitN = x; and x = p->bitN; failed)
3196 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3198 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3237 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3239 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3240 to keep the correct label reference count when adding/removing references
3241 to labels. A peephole file using this is appended to patch #1144962.

3383 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3384 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3385 this might fix SIGSEGVs on MinGW...
3386 * src/SDCCopt.c (killDeadCode): restored original behaviour
3387 (volatile operands might get thrown away though)
3389 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

3474 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
3475 used uninitialized in some cases)

3829 generated for switch statements. For now you need to set the
3830 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3831 Now 4 algorithms for mcs51 jumptable generation are used:
3832 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3833 addresses loaded pc-relative for up to 112 cases and stack-pushing
3834 target addresses loaded with offset from dptr for up to 256 cases.

3864 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3866 * added libc directory. The current version of LibC contains string
3867 functions, ctype functions and macros and some functions of the
3868 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3869 be extensively tested in the future. Standard disclaimer here.
3870 Library is not automatically build yet. But one can build it by
3871 invoking 'make' inside the libc directory.

3881 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3882 * (pic16_storeForReturn): optimized return of 0,
3883 * (genCmp): experimental code for new genCmp which uses PIC18's
3884 special compare&skip instructions. Initial tests fail some times
3885 with variables grater than 1 byte in size, so new code is disabled,
3886 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3888 * (genCast): began a fix to optimize the casting of a bit to another
3889 bit, now assigning a bitfield to another bitfield will fail, sorry,

3894 bits with offset (case PO_GPR_BIT),
3895 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
3897 * (isBankInstruction): modified to return 0 for no banking instruction,
3898 and 1 for banking instruction,
3899 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,

6912 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6914 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6915 loaded with the linker search paths (-L arguments) and the libraries
6916 to be linked with the current source (-l arguments). Changes
6917 currently will affect only the pic16 port.
6918 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6919 include path the port specific paths and port specific libraries,
6920 * gplink command now contains the $3 argument,
6921 * src/pic16/device.h,
6922 * src/pic16/device.c,: structure PIC_device is made public and
6923 renamed to PIC16_device, the same for variable Pics which is renamed

6938 Documenting changes from previous commits.
6939 * configure.in (version 1.56),
6940 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6941 when generating output files to configure the pic16 library,
6942 but now I've commented it out, since gputils aren't installed in the
6943 SF compile farm, so library won't compile
6945 * device/lib/Makefile.in (version 1.56): initially I've added in
6946 target 'all' the prerequestive 'model-pic16' so it compiled the
6947 pic16 library, but now I've commented it out for the same reasons
6949 * added targets 'model-pic16' and 'objects-pic16' to compile the
6951 * added target 'port-specific-objects-pic16' to handle the
6952 generated libraries and copy them into the build/ directory
6953 * added target 'clean-intermediate-pic16' to clean intermediate
6954 files into pic16 directory
6955 * in target 'installdirs' added line to create directory pic16 in
6956 the installation path
6958 * device/include/Makefile.in (version 1.11): in target 'install'
6959 added lines to copy all header files to installation path,
6960 * in target 'installdirs' added line create directory for pic16
6961 headers in the installation path

6977 option so that it actually works. Made it specific to the z80, since
6978 the gbz80 doesn't have these kinds of I/O ports.
6980 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7011 weren't marked as being in the access bank,
7013 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7015 Added portion of GNU PIC Library under the directory
7016 device/include/pic16 and device/lib/pic16. These files
7017 contain the declarations of SFRs for the PIC18Fxx2 devices.
7018 The directory is initialized via configure from toplevel.
7020 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

7048 all over. Telling LaTeX to be less strict with word spacing
7049 to better keep the right margin. Changed some notes about
7050 maintainance of the ports in section 3.2.1 - is it OK like this?
7052 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7092 * src/pic16/peeph.def: all peepholes with movff are commented out,
7093 because there is a problem in the pcode peep optimizer,
7094 * src/pic16/ralloc.c: the register allocator can now reuse local

7187 include information about variables allocated to the overlay
7190 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7192 * as/mcs51/lkmain.c: Help about -Y option

7204 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7206 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7207 (default behaviour).
7209 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7211 A python script to validate compiler diagnostic messages. It can be
7212 used to verify that sdcc complains about bad c source code and
7213 gives a good location of the error.
7214 * support/valdiag/Makefile,
7215 * support/valdiag/valdiag.py,
7216 * support/valdiag/tests/*
7218 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7231 * src/common.h: added ifndef/define/endif macros
7232 around the header file.
7233 Bug reported from Jesus Calvino-Fraga
7235 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7237 * sdcc.spec: updated
7238 * device/include/Makefile.in: don't install CVS directories
7239 * device/lib/Makefile.in: added removal of CVS directories after install
7240 * doc/Makefile: fixed install, added local_icons
7241 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7242 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7243 * src/ds390/gen.c (genRightShift): fixed bug #870788
7244 * src/SDCCast.c (decorateType): fixed bug #870781
7246 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7248 PIC16 port related changes:
7249 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7250 added variable stackPos,
7252 * gen.c: genCall, assignResultValue: added support for
7253 pushing/retrieving function parameters to/from stack,
7254 genFunction,genEndFunction: setup stack frame for the
7256 genAddrOf: will be changed according to bug 863624
7258 * added files genutils.c and genutils.h which contain gen*
7259 debugged and optimised functions extracted from gen.c
7261 * glue.c: added variable 'externs' which holds extern symbols,
7262 pic16emitRegularMap: is modified to properly handle relocatable
7263 symbols under the new scheme,
7264 pic16createInterruptVect: is modified
7265 pic16printPublics: is modified to emit 'global' assembler directives,
7266 added pic16_printExterns to print extern symbols,
7267 pic16glue: initializes stack/frame pointer in the beginning of
7268 the assembly output. Temporary hack, will be corrected later,
7269 because gplink yet does not support stack and SDCC does not
7270 yet support a type of crt0.o object to create the final binary.
7272 * Removed many lines that contain 8051 legacy code.
7273 * The code is finally placed under a 'code' directive.
7274 * Added port specific options.
7276 * _process_pragma: simplified since now we do not need *special*
7277 include file to define SFR registers. But a separate header
7278 will be needed. This will be developed later.
7279 * _pic16_parseOptions: added, parses port specific options:
7280 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7281 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7282 --preplace-udata-with=
7284 * _pic16_setDefaultOptions: modified to initialize section names,
7285 but hack is temporarly out of order since it needs improvement.
7286 * _pic16_genAssemblerPreamble: configuration words are emitted by
7287 their address instead of their name. This part is incomplete and
7288 supports only the 18Fxx2 devices. Other devices will emit an error
7289 during assembly since they do not contain the same set of config
7291 * _pic16_genIVT: is modified,
7293 * pcode.c: added definitions for some hardware registers that are needed
7295 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7296 All PCI entries are updated. Now LFSR is supported.
7297 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7298 * added pic16_newpCodeOpLit2 to support instructions with
7299 two literal arguments
7300 * pic16_pCode2str: corrected code that emits assembler instructions
7301 with two literal operands and those that have an access bit modifier
7302 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7303 this fixes a bug which caused some labels to be lost, when an
7304 assembler directive was added, i.e. banksel,
7305 * pic16_FixRegisterBanking: improved logic that causes the insertion
7307 * InlineFunction: functions that are called once, are not any more
7308 inlined. This can be a port option in the future,
7310 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7312 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7313 hold the corresponding uninitialized symbols,
7314 * pic16_allocProcessorRegister: registers have explicit marked the
7316 * pic16_allocInternalRegister: registers are explicit marked as
7318 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7319 processing list, so bit registers were lost,
7322 * ralloc.h: added field 'accessBank' and original symbol operand
7323 in register definition,
7324 * removed the field isMapped from register definition,
7326 ** Several functions have been removed from various sources:
7327 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7328 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7329 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7330 pic16_assignRelocatableRegisters
7332 ** others have been introduced:
7333 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7334 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7336 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7338 * support/scripts/inc2h.pl: changed definition of BIT_AT
7339 to emit 'sbit at' instead of 'bit at'. This was a request.
7341 PIC16 port related preliminary changes:
7342 * gen.c: prefixed function popRegFromString with
7343 pic16_ and all references to it corrected
7344 * pcode.c: all pic16_pc_* hardware registers prefixed
7345 with underscore (_),
7346 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7347 * ralloc.c: newReg(): when register is REG_SFR then
7348 set address to rIdx,
7349 pic16_allocProcessorRegister(): marks register wasUsed=0
7350 pic16_writeUsedRegs(): added a call to assign processor
7351 registers via pic16_assignFixedRegisters
7353 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7355 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7356 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7357 variables in unused register banks. Also the SSEG is placed
7358 wherever there is enough space for it, and IDATA can be anywhere
7359 in internal RAM. For now compile using -Wl-Y[stack_size].
7360 The mem file is different for this option as well, since it
7361 makes no sense of talking about DSEG lenght.
7363 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7365 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7366 in certain cases, e.g. when ROM assignment, patch provided
7367 from Albert den Haan.
7369 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7511 SDCC_NOGENRAMCLEAR to disable this.
7512 * src/mcs51/peephole.def,
7513 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
7514 (allows non-interrupt and interrupt code to safely compete for a resource
7515 without the non-interrupt code having to disable interrupts)
7517 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7519 * src/SDCCicode.c (geniCodeAdd),

7539 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7541 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165
7543 2003-12-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7612 it breaks with bitfields, extern declarations, and gcse analysis.
7613 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7614 could be assigned through a pointer, so don't complain.

8390 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8392 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8393 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8394 type for bits was changed. It resulted in bit variables becoming
8395 global, which is not permitted in PIC 14 assembly output.

8412 A few small changes that speed up the peephole optimizer.
8416 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8418 Try to make the peephole optimizer smarter by maintaining
8419 an association between the assembly source code and the
8420 iCodes that originated them. Put this information to use
8421 with a new peephole rule condition "notVolatile" so that
8422 the rules can be aggressive yet still safe.
8427 * src/mcs51/peeph.def
8429 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8433 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8434 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8435 if the left or right operand symbols have the accuse flag set.
8437 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8439 Changed the type of the result of the ! (NOT) operator to char;
8440 previously it returned the same type as the source. This allows
8441 us to eliminate all the genFloatNot functions (all of its target
8442 implementations were very buggy) since !float can use the same
8445 * src/SDCCicode.c (ast2iCode): ! returns char

8454 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8455 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8456 during interrupts. Ensure WSAVE is located at a shared bank address.
8457 2. Fixed page selection in some places
8458 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8459 the registers name strings.
8460 4. Fixed "signed / unsigned compare" compiler warnings.
8461 5. The PIC port manages its own allocation of the general purpose
8462 registers, but makes no attempt to reuse them. As a result when
8463 compiling it soon runs out of general purpose registers. Some
8464 additional code was added to the files pcode.c and device.c to walk
8465 through the function call tree and rename the registers so that they
8475 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8476 genPlus() & genMinus() when the result is the same as left or right

8482 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8484 Made bitfield a distinct type from bit so that bitfields
8485 convert as per ANSI C and bits retain their traditional
8486 boolean style behaviour. Implemented bitfield support in
8494 * src/ds390/gen.c: bit v bitfield split
8495 * src/z80/gen.c: New support for bitfields
8496 * support/regression/tests/bitfields.c: reenabled z80,
8499 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8501 Rules 246.x, 247.x relate to bitfields, the others speed up
8502 access to xdata mapped I/O devices.
8504 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8506 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8508 Cleaned up genPackBits and genUnpackBits and added two helper
8509 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8510 for literal assignments in genPackBits (thanks to Frieder for
8516 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8518 Fixed bug #748310 (pointer to function type mishandled when the
8519 function name is omitted). Also fixed a SIGSEGV when a function
8520 attribute (reentrant, etc) is used on a non-function or on a

8551 omitted, the function will not automatically be given an entry
8552 in the interrupt vector table (similar to #pragma NOIV, but

9090 from initialization assignment, since now it is a set,
9091 parseCmdLine uses setParseWithComma for linkOptions, in
9092 linkEdit() linkOptions are accessed with new function indexSet()
9093 which returns the i'th item of a set variable. See SDCCset.c, in
9094 linkEdit() when calling buildCmdLine(), added linkOptions as
9095 last argument. Now users can pass arguments to gplink via the
9096 -Wl option, main() uses pic16glue() to glue up pic16 programs

9110 gpasm complaining and test the linkage with gplink, _linkCmd and
9111 _asmCmd changed to be more gplink and gpasm friendly
9112 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9113 produced an error when parsed, peep rule 12 is added to utilize
9114 movff, but it is commented out since the pCode does not support
9115 yet a command with 2 address arguments

10167 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10168 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

10174 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10175 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10177 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10178 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10180 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10182 * in \sdcc\as\mcs51\ changed these files in order to create an
10183 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10184 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10185 following files to include the previous two files: aslink.dsp,
10186 Makefile.aslink, Makefile.bcc, and Makefile.in.
10188 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10189 .adb instead of .cdb
10191 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10193 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10194 value from option --iram-size.
10196 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10198 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10201 2002-09-18 <wiml AT hhhh.org>
10203 * SDCClrange.h: exposed setFromRange() and setToRange()
10204 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10205 packRegsForAccUse() (bug 542397)
10206 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10207 multiple times and emitting the fetch operations more than once
10208 added aopGetUsesAcc() function to allow binary operators to
10209 fetch their operands in the correct order; made genMinus() emit
10210 compact code for X = LITERAL - Y
10212 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10213 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10214 sprintf() in line 1267.
10216 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10217 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10220 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10221 Changes to aslink (All the changes are marked with 'JCF'):
10223 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10226 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10227 area BSEG. Also moves, if possible, the DATA area down into the internal
10228 ram so more space is available.
10230 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10233 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10234 not bytes. Function summary() which creates a memory usage summary
10235 file with extension .mem. Reports of overlaping stack and small stack
10236 size. If the space for the stack is less than 16 bytes aslink trows a
10239 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10240 the 8051. Option 'y' for memory summary output file.
10242 Changes to sdcc (All the changes are marked with 'JCF'):
10244 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10246 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10247 overlaying area for it (uses RegBankUsed[4]).
10249 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10250 bank zero as used by default. By default aslink locates the stack
10251 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10252 the creation of the .mem file. Delegates the allocation of data area
10253 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10254 the begining of the stack area to aslink.
10256 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10257 glue() in SDCCglue.c creates an area for it.
10259 2002-09-03 Borut Razem <borut.razem AT siol.net>
10260 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10261 sdcc/src/pic/glue.c:
10262 introduced atexit() handler for teporay files removal in case of
10263 errors, assertions, ...
10265 2002-08-29 Borut Razem <borut.razem AT siol.net>
10266 * sdcc/support/cpp2/auto-host_vc_in.h:
10267 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10268 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10269 Maybe there is a similar problem with BORLANDC? It should be checked!
10271 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10272 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10273 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10274 was not executed, and the compiler (cl) launched a warning:
10275 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10277 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10278 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10280 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10281 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10283 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10284 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10285 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10286 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10287 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10288 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10289 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10290 - added Release configuration in VS projects
10291 - review of compiler an linker options
10292 - VC .exe files are generated in bin_vc directory, not to interfere
10293 with binaries generated from other projects (cygwin, mingw, bcc ...)
10295 * sdcc/src/yacc.dsp: added
10297 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10298 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10299 and insert the version number definitions from .version
10301 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10303 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10304 added - genarate auto-host.h using auto-host_vc_in.h as template
10307 removed from CVS, generated automatically
10309 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10310 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10312 2002-08-11 Borut Razem <borut.razem AT siol.net>
10313 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10315 2002-08-10 Borut Razem <borut.razem AT siol.net>
10316 * src/SDCCmain.c (main):
10317 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10318 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10319 The consequence was that some temporary files were not removed.
10322 unification of code in functions tempfilename() and tempfile():
10323 function tempnam() is defined in Visual Studio 6.0 and .NET
10325 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10327 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10328 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10329 - removed compiler command line option /WX: Treats all warnings as errors
10330 - update a list of source files, included into the project
10332 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10333 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10334 changed project type to Generic Project so that can be correcly converted to VS.NET project
10336 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10338 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10340 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10342 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10343 added return 0 statements after assert() to make compiler happy
10345 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10346 added newline in the def file to keep MSC compiler satisfied
10348 * sdcc/src/z80/gen.c:
10349 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10350 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10351 - solved MSC error in function aopDump()
10353 * sdcc_vc.h: define PREFIX as "\\sdcc"
10355 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10356 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
10358 2002-06-22 Scott Dattalo <scott AT dattalo.com>
10359 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10360 - Rewrote the register banking algorithm.
10361 - Added pCode live-range analysis to registers (for now, only non-used and
10362 singly-used registers optimized away)
10364 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10366 * 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.
10368 2002-05-10 Scott Dattalo <scott AT dattalo.com>
10369 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
10371 2002-04-22 Michael Hope <michaelh AT vroom>
