264 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
266 Enabled VPATH feature: changed nearly all Makefiles (149 files).
267 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
269 One basic decision: e.g. src/clean.mk includes further files. In order
270 to make this work there are two solutions:
271 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
272 run configure on them. This way they can use
273 'include $(srcdir)/port-clean.mk'
274 - always include clean.mk by the Makefile at the same level. To avoid
275 that `make clean` tries to include and build Makefile.dep the
276 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
277 implemented, because now even `make uninstall` doesn't create
278 Makefile.in. clean.mk could be eliminated by pasting it in
281 * debugger/mcs51/Makefile.in: build own objects from library sources
282 (SLIB, SDCC) in current directory
284 * configure, configure.in: renamed --disable-device-lib-build in
285 --disable-device-lib; added --enable-doc, the required tools are
286 searched by configure; added result message; the toolchain for the
287 belonging ports are now only built, if the port is enabled.
289 * support/regression/*: all output is written in directory gen, because
290 the fwk and ports directories don't livet in the build tree using vpath
292 * doc/sdccman.lyx: renamed --disable-device-lib-build to
293 --disable-device-lib, added --enable-doc, added section VPATH
295 * sim/ucsim/configure.in,
296 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
297 z80 are enabled by default
299 2006-04-24 Raphael Neider <rneider AT web.de>
301 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
302 to config word, "pic14_"-prefixed some extern functions
303 (pic14_emitConfigWord): emit __config directive(s) if assignment to
304 config word has been found
305 * src/pic/device.h: added prototypes
306 * src/pic/pcode.c: added "pic14_"-prefix where needed

309 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

572 and enabled nesting of critical functions though not for gbz80
573 (genCritical, genEndCritical): added functions
574 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
575 * src/z80/mappings.i: added "ei" to all mappings

581 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
582 archive with gcc 4.1 on mips and wrote the patch"
584 2006-03-16 Raphael Neider <rneider AT web.de>
586 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
587 the left operand is shorter than the result (c* = lit-c* + int),
589 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
592 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
594 * src/.version: increased version number to 2.5.5
595 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
596 linking is done manually in pic16 port's _linkEdit,
597 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
598 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
599 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
600 allocate asmop as AOP_ACC,
601 (aopForRemat): added parameter 'bool result' in function declaration,
602 (pic16_aopGet): return AOP_ACC when accessing WREG,

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

678 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
679 which dumps before the function entry point a data byte which represents
680 the number of the local variables used by the specified function, added
681 'xinst' for initial support for Extended Instruction Support,
682 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
683 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
684 port->fun_prefix anymore (may change later),
685 (genFunction, genEndFunction): do not store/restore local registers for
686 _main (this should take care the --main-return command line option in
688 (genOr): removed some legacy pic-port instructions,
689 * src/pic16/genarith.c (genAddLit): re-enabled old code because
690 performing operations with SFR's causes data to be written more than
691 once to each SFR. Perhaps SFRs should be handled in special cases...
692 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
694 * src/pic16/main.c (_process_pragma): stack bound checking did not take
695 into account for stack starting position,
696 (struct OPTIONS pic16_optionsTable): added command line argument
697 --extended or -y for Extended Instruction Support,
698 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
699 (deassignLRs): *** perhaps the most important change, old 'for' code
700 (commented out for reference), didn't account for some registers which
701 were left marked 'not free' after a pointer operation. The change
702 reduces register usage a lot in some cases

3042 * device/include/stdint.h: added
3043 * device/lib/abs.c: added
3044 * device/lib/labs.c: added
3045 * device/include/stdlib.h: added abs() and labs() prototypes
3046 * device/lib/libsdcc.lib: added abs and labs
3047 * device/include/float.h,
3048 * device/lib/_fsmul.c,
3049 * device/lib/printf_fast.c,
3050 * device/lib/printf_tiny.c: updated comments
3052 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3054 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
3057 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3059 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
3060 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3062 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3064 * device/lib/printf_large.c: removed inline assembly for portability and
3065 readability. Use printf_fast if speed or size are more important.
3066 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3067 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3069 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3071 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3072 prevent compiler warning
3074 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3076 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3077 moved to level 0 and declared as static. Also they are explicit
3078 placed in access bank. This was necessery because some times they
3079 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3080 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3081 optimizations. Currently only compare to unsigned char is implemented,
3082 * src/pic16/gen.c: added fReturnIdx array,
3083 * (struct resolvedIfx) is moved to gen.h and made public,
3084 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3085 * (aopForSym): added an optimization to directly store in stack of
3086 the operand of a SEND iCode,
3087 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3088 but as registers instead (AOP_REG) using the fReturnIdx array,
3089 * (pic16_freeAsmop): remove the freed register from the
3090 _G.sregsAlloc field,
3091 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3092 a compare of 'WREG',
3093 * (pic16_popGetTempRegCond): changed function prototype, now
3094 function takes also a bitVector argument v which holds the current
3095 set of registers that are allocated for stack access by aopForSym,
3096 registers allocated in aopForSym for accessing stack symbols are not
3097 any more part of the functions usedRegs field,
3098 * (genCall): some times aopOp is called for a stack variable to be
3099 send, aopForSym might perform the push, if this is true make sure
3100 that genCall doesn't push the variable twice by testing _G.resDirect,
3101 * (genFunction): changed testing for unspecified interrupt number
3102 from 256 to INTNO_UNSPEC,
3103 * modified selection scheme of frame pointer generation. Previously
3104 if function did use local registers a frame pointer was generated,
3105 now a frame pointer is generated only if function has arguments
3106 (that need PLUSW2 register access), or has stack arguments, or the
3107 compiler is not instructed to omit the frame pointer,
3108 * (genEndFunction): before restoring local registers that were saved
3109 in the function preamble, also restore the registers that *might*
3110 have been allocated for stack access,
3111 * (genRet): removed some old comments,
3112 * (genCmp, the active (RN's) version): added a call to the
3113 pic16_genCmp_special function to perform the compare with a more
3114 robust and optimized way,
3115 * (genInline): a feature has been added in inline code generation,
3116 which allows a wildcard variable substitution when writing inline
3117 assembly. Code is incomplete and experimental therefore undocumented,
3118 * (genCast): changed order of aopOp for result and right to allow
3119 aopForSym to directly load the result if possible,
3120 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3121 perform an optimized compare on some selected special occasions,
3122 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3123 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3124 generate an IVT any more,
3125 * src/pic16/main.c (pic16_optionsTable): added command line option
3127 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3128 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3130 * src/pic16/NOTES: Raphael Neider added in list of active developers
3131 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3132 jumptable_end to prevent bug #,
3133 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3134 inCond and outCond fields,
3135 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3136 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3137 turn off register spilling,
3138 * (packRegsForOneUse): synced with other ports' versions although it
3139 is not used currently,
3140 * (pic16_packRegisters): added an optimization while reading
3141 structure bitfields, some registers may be saved (malloc code is
3142 decreased by 80 bytes)
3144 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3146 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3147 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3148 this can be optimized more?
3150 2005-03-10 Raphael Neider <rneider AT web.de>
3152 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3153 genNearPointerGet): (hopefully) fixed access to bitfields via
3154 pointers (p->bitN = x; and x = p->bitN; failed)
3156 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3789 generated for switch statements. For now you need to set the
3790 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3791 Now 4 algorithms for mcs51 jumptable generation are used:
3792 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3826 * added libc directory. The current version of LibC contains string
3827 functions, ctype functions and macros and some functions of the
3828 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3829 be extensively tested in the future. Standard disclaimer here.

3843 * (genCmp): experimental code for new genCmp which uses PIC18's
3844 special compare&skip instructions. Initial tests fail some times
3845 with variables grater than 1 byte in size, so new code is disabled,
3846 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3848 * (genCast): began a fix to optimize the casting of a bit to another
3849 bit, now assigning a bitfield to another bitfield will fail, sorry,

3863 registers when it shouldn't,
3864 * src/pic16/ralloc.c (allocReg): add preliminary support for
3865 supporting a limited set of temporary registers,
3867 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6872 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
6874 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6875 loaded with the linker search paths (-L arguments) and the libraries
6876 to be linked with the current source (-l arguments). Changes
6877 currently will affect only the pic16 port.
6878 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6879 include path the port specific paths and port specific libraries,
6880 * gplink command now contains the $3 argument,
6881 * src/pic16/device.h,
6882 * src/pic16/device.c,: structure PIC_device is made public and
6883 renamed to PIC16_device, the same for variable Pics which is renamed

6898 Documenting changes from previous commits.
6899 * configure.in (version 1.56),
6900 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6901 when generating output files to configure the pic16 library,
6902 but now I've commented it out, since gputils aren't installed in the
6903 SF compile farm, so library won't compile
6905 * device/lib/Makefile.in (version 1.56): initially I've added in
6906 target 'all' the prerequestive 'model-pic16' so it compiled the
6907 pic16 library, but now I've commented it out for the same reasons
6909 * added targets 'model-pic16' and 'objects-pic16' to compile the
6911 * added target 'port-specific-objects-pic16' to handle the
6912 generated libraries and copy them into the build/ directory
6913 * added target 'clean-intermediate-pic16' to clean intermediate
6914 files into pic16 directory
6915 * in target 'installdirs' added line to create directory pic16 in
6916 the installation path

6919 added lines to copy all header files to installation path,
6920 * in target 'installdirs' added line create directory for pic16
6921 headers in the installation path

6937 option so that it actually works. Made it specific to the z80, since
6938 the gbz80 doesn't have these kinds of I/O ports.
6940 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6942 * device/include/z180.h,

6966 via literal number. The symbol is placed in the corresponding
6967 position of the data ram
6968 * (pic16_dump_section): relocatable and absolute uninitialized
6969 data are now emitted in sorted order to reduce section naming,
6970 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6971 weren't marked as being in the access bank,
6973 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
6975 Added portion of GNU PIC Library under the directory
6976 device/include/pic16 and device/lib/pic16. These files
6977 contain the declarations of SFRs for the PIC18Fxx2 devices.
6978 The directory is initialized via configure from toplevel.
6980 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

7008 all over. Telling LaTeX to be less strict with word spacing
7009 to better keep the right margin. Changed some notes about
7010 maintainance of the ports in section 3.2.1 - is it OK like this?
7012 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7049 UPPER for immediate operands,
7050 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7052 * src/pic16/peeph.def: all peepholes with movff are commented out,
7053 because there is a problem in the pcode peep optimizer,
7054 * src/pic16/ralloc.c: the register allocator can now reuse local

7164 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7166 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7167 (default behaviour).
7169 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7171 A python script to validate compiler diagnostic messages. It can be
7172 used to verify that sdcc complains about bad c source code and
7173 gives a good location of the error.
7174 * support/valdiag/Makefile,
7175 * support/valdiag/valdiag.py,

7195 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7197 * sdcc.spec: updated
7198 * device/include/Makefile.in: don't install CVS directories
7199 * device/lib/Makefile.in: added removal of CVS directories after install
7200 * doc/Makefile: fixed install, added local_icons
7201 * sim/ucsim/gui.src/Makefile.in: fixed an old typo

7206 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7208 PIC16 port related changes:
7209 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7210 added variable stackPos,
7212 * gen.c: genCall, assignResultValue: added support for
7213 pushing/retrieving function parameters to/from stack,
7214 genFunction,genEndFunction: setup stack frame for the
7216 genAddrOf: will be changed according to bug 863624
7218 * added files genutils.c and genutils.h which contain gen*
7219 debugged and optimised functions extracted from gen.c
7221 * glue.c: added variable 'externs' which holds extern symbols,
7222 pic16emitRegularMap: is modified to properly handle relocatable
7223 symbols under the new scheme,
7224 pic16createInterruptVect: is modified
7225 pic16printPublics: is modified to emit 'global' assembler directives,
7226 added pic16_printExterns to print extern symbols,
7227 pic16glue: initializes stack/frame pointer in the beginning of
7228 the assembly output. Temporary hack, will be corrected later,
7229 because gplink yet does not support stack and SDCC does not
7230 yet support a type of crt0.o object to create the final binary.
7232 * Removed many lines that contain 8051 legacy code.
7233 * The code is finally placed under a 'code' directive.
7234 * Added port specific options.
7236 * _process_pragma: simplified since now we do not need *special*
7237 include file to define SFR registers. But a separate header
7238 will be needed. This will be developed later.
7239 * _pic16_parseOptions: added, parses port specific options:
7240 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7241 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7242 --preplace-udata-with=
7244 * _pic16_setDefaultOptions: modified to initialize section names,
7245 but hack is temporarly out of order since it needs improvement.
7246 * _pic16_genAssemblerPreamble: configuration words are emitted by
7247 their address instead of their name. This part is incomplete and
7248 supports only the 18Fxx2 devices. Other devices will emit an error
7249 during assembly since they do not contain the same set of config
7251 * _pic16_genIVT: is modified,
7253 * pcode.c: added definitions for some hardware registers that are needed
7255 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7256 All PCI entries are updated. Now LFSR is supported.
7257 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7258 * added pic16_newpCodeOpLit2 to support instructions with
7259 two literal arguments
7260 * pic16_pCode2str: corrected code that emits assembler instructions
7261 with two literal operands and those that have an access bit modifier
7262 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7263 this fixes a bug which caused some labels to be lost, when an
7264 assembler directive was added, i.e. banksel,
7265 * pic16_FixRegisterBanking: improved logic that causes the insertion
7267 * InlineFunction: functions that are called once, are not any more
7268 inlined. This can be a port option in the future,
7270 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7272 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7273 hold the corresponding uninitialized symbols,
7274 * pic16_allocProcessorRegister: registers have explicit marked the
7276 * pic16_allocInternalRegister: registers are explicit marked as
7278 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7279 processing list, so bit registers were lost,
7282 * ralloc.h: added field 'accessBank' and original symbol operand
7283 in register definition,
7284 * removed the field isMapped from register definition,
7286 ** Several functions have been removed from various sources:
7287 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7288 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7289 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7290 pic16_assignRelocatableRegisters
7292 ** others have been introduced:
7293 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7294 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7296 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7298 * support/scripts/inc2h.pl: changed definition of BIT_AT
7299 to emit 'sbit at' instead of 'bit at'. This was a request.
7301 PIC16 port related preliminary changes:
7302 * gen.c: prefixed function popRegFromString with
7303 pic16_ and all references to it corrected
7304 * pcode.c: all pic16_pc_* hardware registers prefixed
7305 with underscore (_),
7306 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7307 * ralloc.c: newReg(): when register is REG_SFR then
7308 set address to rIdx,
7309 pic16_allocProcessorRegister(): marks register wasUsed=0
7310 pic16_writeUsedRegs(): added a call to assign processor
7311 registers via pic16_assignFixedRegisters
7313 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7315 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7316 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7317 variables in unused register banks. Also the SSEG is placed
7318 wherever there is enough space for it, and IDATA can be anywhere
7319 in internal RAM. For now compile using -Wl-Y[stack_size].
7320 The mem file is different for this option as well, since it
7321 makes no sense of talking about DSEG lenght.
7323 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7325 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7326 in certain cases, e.g. when ROM assignment, patch provided
7327 from Albert den Haan.
7329 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7472 * src/mcs51/peephole.def,
7473 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
7474 (allows non-interrupt and interrupt code to safely compete for a resource

8214 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
8215 support for standard C idiom of memory mapped variables; for
8216 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8217 to xdata int at 0x1234 tempvar = 1.
8218 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8219 provided by Akiya ISHIDA

8235 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8237 Fixed bug #621531 (const & volatile confusion in the type chain).
8238 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

8330 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8331 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8332 fetching of the pointer
8333 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8334 copied from genNearPointerSet()
8335 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8336 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8337 If they pop r0/r1 they must be called in the opposite order than aopOp().
8338 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8339 (resp. --stack-auto), prepared for --xstack

8348 these ports have their own __sdcc_external_start()
8350 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8352 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8353 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8354 type for bits was changed. It resulted in bit variables becoming
8355 global, which is not permitted in PIC 14 assembly output.
8357 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8359 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8372 A few small changes that speed up the peephole optimizer.
8376 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8378 Try to make the peephole optimizer smarter by maintaining
8379 an association between the assembly source code and the
8380 iCodes that originated them. Put this information to use
8381 with a new peephole rule condition "notVolatile" so that
8382 the rules can be aggressive yet still safe.
8387 * src/mcs51/peeph.def
8389 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8393 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8394 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8395 if the left or right operand symbols have the accuse flag set.
8397 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8399 Changed the type of the result of the ! (NOT) operator to char;
8400 previously it returned the same type as the source. This allows
8401 us to eliminate all the genFloatNot functions (all of its target
8402 implementations were very buggy) since !float can use the same
8405 * src/SDCCicode.c (ast2iCode): ! returns char
8406 * src/mcs51/gen.c (genNot, genNotFloat),
8407 * src/ds390/gen.c (genNot, genNotFloat),
8408 * src/z80/gen.c (genNot, genNotFloat),
8409 * src/pic/gen.c (genNot, genNotFloat),

8412 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8414 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8415 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8416 during interrupts. Ensure WSAVE is located at a shared bank address.
8417 2. Fixed page selection in some places
8418 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8419 the registers name strings.
8420 4. Fixed "signed / unsigned compare" compiler warnings.
8421 5. The PIC port manages its own allocation of the general purpose
8422 registers, but makes no attempt to reuse them. As a result when
8423 compiling it soon runs out of general purpose registers. Some
8424 additional code was added to the files pcode.c and device.c to walk
8425 through the function call tree and rename the registers so that they
8435 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8436 genPlus() & genMinus() when the result is the same as left or right
8438 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8442 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8444 Made bitfield a distinct type from bit so that bitfields
8445 convert as per ANSI C and bits retain their traditional
8446 boolean style behaviour. Implemented bitfield support in
8454 * src/ds390/gen.c: bit v bitfield split
8455 * src/z80/gen.c: New support for bitfields
8456 * support/regression/tests/bitfields.c: reenabled z80,
8459 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8461 Rules 246.x, 247.x relate to bitfields, the others speed up
8462 access to xdata mapped I/O devices.
8464 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8466 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8468 Cleaned up genPackBits and genUnpackBits and added two helper
8469 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8470 for literal assignments in genPackBits (thanks to Frieder for
8476 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8478 Fixed bug #748310 (pointer to function type mishandled when the
8479 function name is omitted). Also fixed a SIGSEGV when a function
8480 attribute (reentrant, etc) is used on a non-function or on a
8481 function but misplaced before the parameter list.
8483 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8485 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8486 * support/Util/SDCCerr.h,
8487 * support/Util/SDCCerr.c: Added func attr misuse error msg
8489 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8491 Fixed bug #787649 by anonymous
8492 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
8493 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
8495 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8508 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8510 Made the constant following the "interrupt" keyword optional. If
8511 omitted, the function will not automatically be given an entry
8512 in the interrupt vector table (similar to #pragma NOIV, but
8513 less syntacticly kludgy). The interrupt number is also now
8514 range checked. Also fixed a bug in the high order bit example

8522 * support/Util/SDCCerr.h
8525 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8527 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
8528 * src/SDCCicode.c (operandOperation): rewritten some ops
8529 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8530 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8532 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8533 be re-activated by defining REDUCE_LITERALS)
8534 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8535 unsigned, but are signed by default

9044 added if/endif conditional macros to remove options help
9045 messages from optionsTable when a port is not configured, added
9046 support for the PIc16 port in the ports table, when executing
9047 the compiler with no port specified on command line, a default
9048 port is selected with the new macro DEFAULT_PORT which is
9049 defined in port.h, in setDefaultOptions() linkOptions is removed
9050 from initialization assignment, since now it is a set,
9051 parseCmdLine uses setParseWithComma for linkOptions, in
9052 linkEdit() linkOptions are accessed with new function indexSet()
9053 which returns the i'th item of a set variable. See SDCCset.c, in
9054 linkEdit() when calling buildCmdLine(), added linkOptions as
9055 last argument. Now users can pass arguments to gplink via the
9056 -Wl option, main() uses pic16glue() to glue up pic16 programs

9070 gpasm complaining and test the linkage with gplink, _linkCmd and
9071 _asmCmd changed to be more gplink and gpasm friendly
9072 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9073 produced an error when parsed, peep rule 12 is added to utilize
9074 movff, but it is commented out since the pCode does not support
9075 yet a command with 2 address arguments
9077 2003-05-18 <johan AT balder>
9079 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10137 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10138 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10140 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10142 * in \sdcc\as\mcs51\ changed these files in order to create an
10143 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10144 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10145 following files to include the previous two files: aslink.dsp,
10146 Makefile.aslink, Makefile.bcc, and Makefile.in.
10148 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10149 .adb instead of .cdb
10151 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10153 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10154 value from option --iram-size.
10156 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10158 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10161 2002-09-18 <wiml AT hhhh.org>
10163 * SDCClrange.h: exposed setFromRange() and setToRange()
10164 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10165 packRegsForAccUse() (bug 542397)
10166 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10167 multiple times and emitting the fetch operations more than once
10168 added aopGetUsesAcc() function to allow binary operators to
10169 fetch their operands in the correct order; made genMinus() emit
10170 compact code for X = LITERAL - Y
10172 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10173 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10174 sprintf() in line 1267.
10176 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10177 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10180 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10181 Changes to aslink (All the changes are marked with 'JCF'):
10183 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10186 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10187 area BSEG. Also moves, if possible, the DATA area down into the internal
10188 ram so more space is available.
10190 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10193 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10194 not bytes. Function summary() which creates a memory usage summary
10195 file with extension .mem. Reports of overlaping stack and small stack
10196 size. If the space for the stack is less than 16 bytes aslink trows a
10199 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10200 the 8051. Option 'y' for memory summary output file.
10202 Changes to sdcc (All the changes are marked with 'JCF'):
10204 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10206 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10207 overlaying area for it (uses RegBankUsed[4]).
10209 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10210 bank zero as used by default. By default aslink locates the stack
10211 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10212 the creation of the .mem file. Delegates the allocation of data area
10213 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10214 the begining of the stack area to aslink.
10216 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10217 glue() in SDCCglue.c creates an area for it.
10219 2002-09-03 Borut Razem <borut.razem AT siol.net>
10220 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10221 sdcc/src/pic/glue.c:
10222 introduced atexit() handler for teporay files removal in case of
10223 errors, assertions, ...
10225 2002-08-29 Borut Razem <borut.razem AT siol.net>
10226 * sdcc/support/cpp2/auto-host_vc_in.h:
10227 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10228 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10229 Maybe there is a similar problem with BORLANDC? It should be checked!
10231 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10232 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10233 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10234 was not executed, and the compiler (cl) launched a warning:
10235 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10237 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10238 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10240 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10241 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10243 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10244 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10245 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10246 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10247 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10248 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10249 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10250 - added Release configuration in VS projects
10251 - review of compiler an linker options
10252 - VC .exe files are generated in bin_vc directory, not to interfere
10253 with binaries generated from other projects (cygwin, mingw, bcc ...)
10255 * sdcc/src/yacc.dsp: added
10257 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10258 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10259 and insert the version number definitions from .version
10261 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10263 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10264 added - genarate auto-host.h using auto-host_vc_in.h as template
10267 removed from CVS, generated automatically
10269 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10270 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10272 2002-08-11 Borut Razem <borut.razem AT siol.net>
10273 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10275 2002-08-10 Borut Razem <borut.razem AT siol.net>
10276 * src/SDCCmain.c (main):
10277 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10278 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10279 The consequence was that some temporary files were not removed.
10282 unification of code in functions tempfilename() and tempfile():
10283 function tempnam() is defined in Visual Studio 6.0 and .NET
10285 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10287 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10288 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10289 - removed compiler command line option /WX: Treats all warnings as errors
10290 - update a list of source files, included into the project
10292 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10293 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10294 changed project type to Generic Project so that can be correcly converted to VS.NET project
10296 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10298 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10300 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10302 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10303 added return 0 statements after assert() to make compiler happy
10305 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10306 added newline in the def file to keep MSC compiler satisfied
10308 * sdcc/src/z80/gen.c:
10309 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10310 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10311 - solved MSC error in function aopDump()
10313 * sdcc_vc.h: define PREFIX as "\\sdcc"
10315 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10316 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
10318 2002-06-22 Scott Dattalo <scott AT dattalo.com>
10319 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10320 - Rewrote the register banking algorithm.
10321 - Added pCode live-range analysis to registers (for now, only non-used and
10322 singly-used registers optimized away)
10324 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10326 * 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.

10351 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10353 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10355 2002-03-28 Johan Knol <johan AT balder>
10357 * src/SDCCval.c: fixed bug #532436
10359 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10361 Added "char *Processor" field to the port structure.
10364 Added -p option. Allows port dependent processor to be specified.
10367 Initialized the new field char *Processor field to NULL in all ports
10370 Compiler generated registers for interrupt context saving
10371 were not getting allocated.
10373 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10376 Fixed left shift. Will promote the left side of a left shift
10377 if a) left shifting more than size of operand or b) when assigned
10378 to something size > size of left side
10380 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10382 tons of changes. Register allocation has been
10383 rewritten. Added customization for the various PICs. Flow
10384 analysis is restructured. ...
10386 * src/pic/device.h:
10389 * src/pic/device.c:
10390 Added. device.c is a PIC port hack to accomodate variations
10393 2002-03-13 Michael Hope <michaelh AT vroom>
10395 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10397 2002-03-04 johanknol <johanknol AT manik>
10399 * /src/SDCCval.c: fixed
10401 const unsigned char arr[][2] = { { 0, 1 } };
10402 t18.c:1: error: Initializer element is not constant
10404 2002-03-04 bela <bela AT manik>
