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

368 fixes #1469504 and #1474602,
369 (pCodeRegOptimizeRegUsage): fixed typo in comment

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

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

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

3025 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3026 always available in leading double underscore form. The C99 support is
3027 mostly missing, but it's a start.
3028 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3029 reserved identifier "__data".
3031 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3075 immedDom() returning wrong block; probably fixes bug #1160833)
3077 2005-03-20 Borut Razem <borut.razem AT siol.net>
3079 * support/scripts/inc2h.pl: WIN32 port
3081 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3083 * device/lib/makefile.in: added abs.c and labs.c
3085 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3087 * device/include/stdint.h: added
3088 * device/lib/abs.c: added
3089 * device/lib/labs.c: added
3090 * device/include/stdlib.h: added abs() and labs() prototypes

3097 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3099 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed

3105 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3107 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3109 * device/lib/printf_large.c: removed inline assembly for portability and
3110 readability. Use printf_fast if speed or size are more important.
3111 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3112 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3114 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3116 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3117 prevent compiler warning
3119 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3121 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3122 moved to level 0 and declared as static. Also they are explicit
3123 placed in access bank. This was necessery because some times they
3124 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3125 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3126 optimizations. Currently only compare to unsigned char is implemented,
3127 * src/pic16/gen.c: added fReturnIdx array,
3128 * (struct resolvedIfx) is moved to gen.h and made public,
3129 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3130 * (aopForSym): added an optimization to directly store in stack of
3131 the operand of a SEND iCode,
3132 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3133 but as registers instead (AOP_REG) using the fReturnIdx array,
3134 * (pic16_freeAsmop): remove the freed register from the
3135 _G.sregsAlloc field,
3136 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3137 a compare of 'WREG',
3138 * (pic16_popGetTempRegCond): changed function prototype, now
3139 function takes also a bitVector argument v which holds the current
3140 set of registers that are allocated for stack access by aopForSym,
3141 registers allocated in aopForSym for accessing stack symbols are not
3142 any more part of the functions usedRegs field,
3143 * (genCall): some times aopOp is called for a stack variable to be
3144 send, aopForSym might perform the push, if this is true make sure
3145 that genCall doesn't push the variable twice by testing _G.resDirect,
3146 * (genFunction): changed testing for unspecified interrupt number
3147 from 256 to INTNO_UNSPEC,
3148 * modified selection scheme of frame pointer generation. Previously
3149 if function did use local registers a frame pointer was generated,
3150 now a frame pointer is generated only if function has arguments
3151 (that need PLUSW2 register access), or has stack arguments, or the
3152 compiler is not instructed to omit the frame pointer,
3153 * (genEndFunction): before restoring local registers that were saved
3154 in the function preamble, also restore the registers that *might*
3155 have been allocated for stack access,
3156 * (genRet): removed some old comments,
3157 * (genCmp, the active (RN's) version): added a call to the
3158 pic16_genCmp_special function to perform the compare with a more
3159 robust and optimized way,
3160 * (genInline): a feature has been added in inline code generation,
3161 which allows a wildcard variable substitution when writing inline
3162 assembly. Code is incomplete and experimental therefore undocumented,
3163 * (genCast): changed order of aopOp for result and right to allow
3164 aopForSym to directly load the result if possible,
3165 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3166 perform an optimized compare on some selected special occasions,
3167 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3168 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3169 generate an IVT any more,
3170 * src/pic16/main.c (pic16_optionsTable): added command line option
3172 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3173 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3175 * src/pic16/NOTES: Raphael Neider added in list of active developers
3176 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3177 jumptable_end to prevent bug #,
3178 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3179 inCond and outCond fields,
3180 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3181 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3182 turn off register spilling,
3183 * (packRegsForOneUse): synced with other ports' versions although it
3184 is not used currently,
3185 * (pic16_packRegisters): added an optimization while reading
3186 structure bitfields, some registers may be saved (malloc code is
3187 decreased by 80 bytes)
3189 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3191 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3192 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3193 this can be optimized more?
3195 2005-03-10 Raphael Neider <rneider AT web.de>
3197 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3198 genNearPointerGet): (hopefully) fixed access to bitfields via
3199 pointers (p->bitN = x; and x = p->bitN; failed)

3388 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3389 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3390 this might fix SIGSEGVs on MinGW...
3391 * src/SDCCopt.c (killDeadCode): restored original behaviour
3392 (volatile operands might get thrown away though)
3394 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

3833 Adding support for replacing ljmps with sjmps in jumptables
3834 generated for switch statements. For now you need to set the
3835 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3836 Now 4 algorithms for mcs51 jumptable generation are used:
3837 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
3838 addresses loaded pc-relative for up to 112 cases and stack-pushing
3839 target addresses loaded with offset from dptr for up to 256 cases.

3867 to call when a stack overflow occurs,
3868 * (malloc.h): added CVS Id tag,
3869 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
3871 * added libc directory. The current version of LibC contains string
3872 functions, ctype functions and macros and some functions of the
3873 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3874 be extensively tested in the future. Standard disclaimer here.
3875 Library is not automatically build yet. But one can build it by
3876 invoking 'make' inside the libc directory.
3877 * added ADC library under libio. Preliminary version yet.

3883 temporary registers, its a buggy feature and will be removed,
3884 * (pic16_popGet): set register instance field in AOP_CRY,
3885 * (pic16_outBitC): fixed for results in size greater than 1,
3886 * (genUminusFloat): fixed for pic16, ported code from mcs51,
3887 * (pic16_storeForReturn): optimized return of 0,
3888 * (genCmp): experimental code for new genCmp which uses PIC18's
3889 special compare&skip instructions. Initial tests fail some times
3890 with variables grater than 1 byte in size, so new code is disabled,
3891 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3893 * (genCast): began a fix to optimize the casting of a bit to another
3894 bit, now assigning a bitfield to another bitfield will fail, sorry,
3895 * src/pic16/main.c: disabled the use of lr-support feature,
3896 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

6917 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6919 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6920 loaded with the linker search paths (-L arguments) and the libraries
6921 to be linked with the current source (-l arguments). Changes
6922 currently will affect only the pic16 port.
6923 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6924 include path the port specific paths and port specific libraries,
6925 * gplink command now contains the $3 argument,
6926 * src/pic16/device.h,
6927 * src/pic16/device.c,: structure PIC_device is made public and
6928 renamed to PIC16_device, the same for variable Pics which is renamed

6943 Documenting changes from previous commits.
6944 * configure.in (version 1.56),
6945 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6946 when generating output files to configure the pic16 library,
6947 but now I've commented it out, since gputils aren't installed in the
6948 SF compile farm, so library won't compile
6950 * device/lib/Makefile.in (version 1.56): initially I've added in
6951 target 'all' the prerequestive 'model-pic16' so it compiled the
6952 pic16 library, but now I've commented it out for the same reasons
6954 * added targets 'model-pic16' and 'objects-pic16' to compile the
6956 * added target 'port-specific-objects-pic16' to handle the
6957 generated libraries and copy them into the build/ directory
6958 * added target 'clean-intermediate-pic16' to clean intermediate
6959 files into pic16 directory
6960 * in target 'installdirs' added line to create directory pic16 in
6961 the installation path
6963 * device/include/Makefile.in (version 1.11): in target 'install'
6964 added lines to copy all header files to installation path,
6965 * in target 'installdirs' added line create directory for pic16
6966 headers in the installation path

6982 option so that it actually works. Made it specific to the z80, since
6983 the gbz80 doesn't have these kinds of I/O ports.
6985 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7016 weren't marked as being in the access bank,
7018 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7020 Added portion of GNU PIC Library under the directory
7021 device/include/pic16 and device/lib/pic16. These files
7022 contain the declarations of SFRs for the PIC18Fxx2 devices.
7023 The directory is initialized via configure from toplevel.
7025 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

7053 all over. Telling LaTeX to be less strict with word spacing
7054 to better keep the right margin. Changed some notes about
7055 maintainance of the ports in section 3.2.1 - is it OK like this?
7057 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7097 * src/pic16/peeph.def: all peepholes with movff are commented out,
7098 because there is a problem in the pcode peep optimizer,
7099 * src/pic16/ralloc.c: the register allocator can now reuse local

7176 2004-01-07 Borut Razem <borut.razem AT siol.net>
7178 * support/scripts/sdcc.nsi: update PATH
7179 * support/scripts/sdcc.ico: craeted

7192 include information about variables allocated to the overlay
7195 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7197 * as/mcs51/lkmain.c: Help about -Y option

7209 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7211 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7212 (default behaviour).
7214 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7216 A python script to validate compiler diagnostic messages. It can be
7217 used to verify that sdcc complains about bad c source code and
7218 gives a good location of the error.
7219 * support/valdiag/Makefile,
7220 * support/valdiag/valdiag.py,
7221 * support/valdiag/tests/*
7223 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7236 * src/common.h: added ifndef/define/endif macros
7237 around the header file.
7238 Bug reported from Jesus Calvino-Fraga
7240 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7242 * sdcc.spec: updated
7243 * device/include/Makefile.in: don't install CVS directories
7244 * device/lib/Makefile.in: added removal of CVS directories after install
7245 * doc/Makefile: fixed install, added local_icons
7246 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7247 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7248 * src/ds390/gen.c (genRightShift): fixed bug #870788
7249 * src/SDCCast.c (decorateType): fixed bug #870781
7251 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7253 PIC16 port related changes:
7254 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7255 added variable stackPos,
7257 * gen.c: genCall, assignResultValue: added support for
7258 pushing/retrieving function parameters to/from stack,
7259 genFunction,genEndFunction: setup stack frame for the
7261 genAddrOf: will be changed according to bug 863624
7263 * added files genutils.c and genutils.h which contain gen*
7264 debugged and optimised functions extracted from gen.c
7266 * glue.c: added variable 'externs' which holds extern symbols,
7267 pic16emitRegularMap: is modified to properly handle relocatable
7268 symbols under the new scheme,
7269 pic16createInterruptVect: is modified
7270 pic16printPublics: is modified to emit 'global' assembler directives,
7271 added pic16_printExterns to print extern symbols,
7272 pic16glue: initializes stack/frame pointer in the beginning of
7273 the assembly output. Temporary hack, will be corrected later,
7274 because gplink yet does not support stack and SDCC does not
7275 yet support a type of crt0.o object to create the final binary.
7277 * Removed many lines that contain 8051 legacy code.
7278 * The code is finally placed under a 'code' directive.
7279 * Added port specific options.
7281 * _process_pragma: simplified since now we do not need *special*
7282 include file to define SFR registers. But a separate header
7283 will be needed. This will be developed later.
7284 * _pic16_parseOptions: added, parses port specific options:
7285 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7286 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7287 --preplace-udata-with=
7289 * _pic16_setDefaultOptions: modified to initialize section names,
7290 but hack is temporarly out of order since it needs improvement.
7291 * _pic16_genAssemblerPreamble: configuration words are emitted by
7292 their address instead of their name. This part is incomplete and
7293 supports only the 18Fxx2 devices. Other devices will emit an error
7294 during assembly since they do not contain the same set of config
7296 * _pic16_genIVT: is modified,
7298 * pcode.c: added definitions for some hardware registers that are needed
7300 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7301 All PCI entries are updated. Now LFSR is supported.
7302 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7303 * added pic16_newpCodeOpLit2 to support instructions with
7304 two literal arguments
7305 * pic16_pCode2str: corrected code that emits assembler instructions
7306 with two literal operands and those that have an access bit modifier
7307 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7308 this fixes a bug which caused some labels to be lost, when an
7309 assembler directive was added, i.e. banksel,
7310 * pic16_FixRegisterBanking: improved logic that causes the insertion
7312 * InlineFunction: functions that are called once, are not any more
7313 inlined. This can be a port option in the future,
7315 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7317 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7318 hold the corresponding uninitialized symbols,
7319 * pic16_allocProcessorRegister: registers have explicit marked the
7321 * pic16_allocInternalRegister: registers are explicit marked as
7323 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7324 processing list, so bit registers were lost,
7327 * ralloc.h: added field 'accessBank' and original symbol operand
7328 in register definition,
7329 * removed the field isMapped from register definition,
7331 ** Several functions have been removed from various sources:
7332 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7333 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7334 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7335 pic16_assignRelocatableRegisters
7337 ** others have been introduced:
7338 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7339 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7341 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7343 * support/scripts/inc2h.pl: changed definition of BIT_AT
7344 to emit 'sbit at' instead of 'bit at'. This was a request.
7346 PIC16 port related preliminary changes:
7347 * gen.c: prefixed function popRegFromString with
7348 pic16_ and all references to it corrected
7349 * pcode.c: all pic16_pc_* hardware registers prefixed
7350 with underscore (_),
7351 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7352 * ralloc.c: newReg(): when register is REG_SFR then
7353 set address to rIdx,
7354 pic16_allocProcessorRegister(): marks register wasUsed=0
7355 pic16_writeUsedRegs(): added a call to assign processor
7356 registers via pic16_assignFixedRegisters
7358 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7360 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7361 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7362 variables in unused register banks. Also the SSEG is placed
7363 wherever there is enough space for it, and IDATA can be anywhere
7364 in internal RAM. For now compile using -Wl-Y[stack_size].
7365 The mem file is different for this option as well, since it
7366 makes no sense of talking about DSEG lenght.
7368 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7370 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7371 in certain cases, e.g. when ROM assignment, patch provided
7372 from Albert den Haan.
7374 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7516 SDCC_NOGENRAMCLEAR to disable this.
7517 * src/mcs51/peephole.def,
7518 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
7519 (allows non-interrupt and interrupt code to safely compete for a resource
7520 without the non-interrupt code having to disable interrupts)
7522 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7524 * src/SDCCicode.c (geniCodeAdd),

7544 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7546 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165
7548 2003-12-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7616 revision 1.188 (access to fields of a structure at an absolute address);
7617 it breaks with bitfields, extern declarations, and gcse analysis.
7618 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7619 could be assigned through a pointer, so don't complain.

8397 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8398 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8399 type for bits was changed. It resulted in bit variables becoming
8400 global, which is not permitted in PIC 14 assembly output.

8417 A few small changes that speed up the peephole optimizer.
8421 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8423 Try to make the peephole optimizer smarter by maintaining
8424 an association between the assembly source code and the
8425 iCodes that originated them. Put this information to use
8426 with a new peephole rule condition "notVolatile" so that
8427 the rules can be aggressive yet still safe.
8432 * src/mcs51/peeph.def
8434 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8438 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8439 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8440 if the left or right operand symbols have the accuse flag set.
8442 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8444 Changed the type of the result of the ! (NOT) operator to char;
8445 previously it returned the same type as the source. This allows
8446 us to eliminate all the genFloatNot functions (all of its target
8447 implementations were very buggy) since !float can use the same
8450 * src/SDCCicode.c (ast2iCode): ! returns char

8459 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8460 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8461 during interrupts. Ensure WSAVE is located at a shared bank address.
8462 2. Fixed page selection in some places
8463 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8464 the registers name strings.
8465 4. Fixed "signed / unsigned compare" compiler warnings.
8466 5. The PIC port manages its own allocation of the general purpose
8467 registers, but makes no attempt to reuse them. As a result when
8468 compiling it soon runs out of general purpose registers. Some
8469 additional code was added to the files pcode.c and device.c to walk
8470 through the function call tree and rename the registers so that they
8480 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8481 genPlus() & genMinus() when the result is the same as left or right

8487 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8489 Made bitfield a distinct type from bit so that bitfields
8490 convert as per ANSI C and bits retain their traditional
8491 boolean style behaviour. Implemented bitfield support in
8499 * src/ds390/gen.c: bit v bitfield split
8500 * src/z80/gen.c: New support for bitfields
8501 * support/regression/tests/bitfields.c: reenabled z80,
8504 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8506 Rules 246.x, 247.x relate to bitfields, the others speed up
8507 access to xdata mapped I/O devices.
8509 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8511 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8513 Cleaned up genPackBits and genUnpackBits and added two helper
8514 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8515 for literal assignments in genPackBits (thanks to Frieder for
8521 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8523 Fixed bug #748310 (pointer to function type mishandled when the
8524 function name is omitted). Also fixed a SIGSEGV when a function

9095 from initialization assignment, since now it is a set,
9096 parseCmdLine uses setParseWithComma for linkOptions, in
9097 linkEdit() linkOptions are accessed with new function indexSet()
9098 which returns the i'th item of a set variable. See SDCCset.c, in
9099 linkEdit() when calling buildCmdLine(), added linkOptions as
9100 last argument. Now users can pass arguments to gplink via the
9101 -Wl option, main() uses pic16glue() to glue up pic16 programs

9115 gpasm complaining and test the linkage with gplink, _linkCmd and
9116 _asmCmd changed to be more gplink and gpasm friendly
9117 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9118 produced an error when parsed, peep rule 12 is added to utilize
9119 movff, but it is commented out since the pCode does not support
9120 yet a command with 2 address arguments

10172 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10173 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

10179 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10180 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10182 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10183 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10185 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10187 * in \sdcc\as\mcs51\ changed these files in order to create an
10188 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10189 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10190 following files to include the previous two files: aslink.dsp,
10191 Makefile.aslink, Makefile.bcc, and Makefile.in.
10193 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10194 .adb instead of .cdb
10196 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10198 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10199 value from option --iram-size.
10201 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10203 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10206 2002-09-18 <wiml AT hhhh.org>
10208 * SDCClrange.h: exposed setFromRange() and setToRange()
10209 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10210 packRegsForAccUse() (bug 542397)
10211 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10212 multiple times and emitting the fetch operations more than once
10213 added aopGetUsesAcc() function to allow binary operators to
10214 fetch their operands in the correct order; made genMinus() emit
10215 compact code for X = LITERAL - Y
10217 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10218 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10219 sprintf() in line 1267.
10221 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10222 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10225 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10226 Changes to aslink (All the changes are marked with 'JCF'):
10228 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10231 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10232 area BSEG. Also moves, if possible, the DATA area down into the internal
10233 ram so more space is available.
10235 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10238 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10239 not bytes. Function summary() which creates a memory usage summary
10240 file with extension .mem. Reports of overlaping stack and small stack
10241 size. If the space for the stack is less than 16 bytes aslink trows a
10244 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10245 the 8051. Option 'y' for memory summary output file.
10247 Changes to sdcc (All the changes are marked with 'JCF'):
10249 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10251 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10252 overlaying area for it (uses RegBankUsed[4]).
10254 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10255 bank zero as used by default. By default aslink locates the stack
10256 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10257 the creation of the .mem file. Delegates the allocation of data area
10258 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10259 the begining of the stack area to aslink.
10261 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10262 glue() in SDCCglue.c creates an area for it.
10264 2002-09-03 Borut Razem <borut.razem AT siol.net>
10265 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10266 sdcc/src/pic/glue.c:
10267 introduced atexit() handler for teporay files removal in case of
10268 errors, assertions, ...
10270 2002-08-29 Borut Razem <borut.razem AT siol.net>
10271 * sdcc/support/cpp2/auto-host_vc_in.h:
10272 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10273 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10274 Maybe there is a similar problem with BORLANDC? It should be checked!
10276 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10277 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10278 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10279 was not executed, and the compiler (cl) launched a warning:
10280 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10282 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10283 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10285 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10286 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10288 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10289 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10290 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10291 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10292 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10293 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10294 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10295 - added Release configuration in VS projects
10296 - review of compiler an linker options
10297 - VC .exe files are generated in bin_vc directory, not to interfere
10298 with binaries generated from other projects (cygwin, mingw, bcc ...)
10300 * sdcc/src/yacc.dsp: added
10302 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10303 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10304 and insert the version number definitions from .version
10306 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10308 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10309 added - genarate auto-host.h using auto-host_vc_in.h as template
10312 removed from CVS, generated automatically
10314 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10315 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10317 2002-08-11 Borut Razem <borut.razem AT siol.net>
10318 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10320 2002-08-10 Borut Razem <borut.razem AT siol.net>
10321 * src/SDCCmain.c (main):
10322 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10323 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10324 The consequence was that some temporary files were not removed.
10327 unification of code in functions tempfilename() and tempfile():
10328 function tempnam() is defined in Visual Studio 6.0 and .NET
10330 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10332 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10333 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10334 - removed compiler command line option /WX: Treats all warnings as errors
10335 - update a list of source files, included into the project
10337 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10338 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10339 changed project type to Generic Project so that can be correcly converted to VS.NET project
10341 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10343 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10345 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10347 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10348 added return 0 statements after assert() to make compiler happy
10350 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10351 added newline in the def file to keep MSC compiler satisfied
10353 * sdcc/src/z80/gen.c:
10354 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10355 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10356 - solved MSC error in function aopDump()
10358 * sdcc_vc.h: define PREFIX as "\\sdcc"
10360 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10361 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
10363 2002-06-22 Scott Dattalo <scott AT dattalo.com>
10364 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10365 - Rewrote the register banking algorithm.
10366 - Added pCode live-range analysis to registers (for now, only non-used and
10367 singly-used registers optimized away)
10369 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10371 * 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.
10373 2002-05-10 Scott Dattalo <scott AT dattalo.com>
10374 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
10376 2002-04-22 Michael Hope <michaelh AT vroom>
