251 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
253 Enabled VPATH feature: changed nearly all Makefiles (149 files).
254 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
256 One basic decision: e.g. src/clean.mk includes further files. In order
257 to make this work there are two solutions:
258 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
259 run configure on them. This way they can use
260 'include $(srcdir)/port-clean.mk'
261 - always include clean.mk by the Makefile at the same level. To avoid
262 that `make clean` tries to include and build Makefile.dep the
263 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
264 implemented, because now even `make uninstall` doesn't create
265 Makefile.in. clean.mk could be eliminated by pasting it in
268 * debugger/mcs51/Makefile.in: build own objects from library sources
269 (SLIB, SDCC) in current directory
271 * configure, configure.in: renamed --disable-device-lib-build in
272 --disable-device-lib; added --enable-doc, the required tools are
273 searched by configure; added result message; the toolchain for the
274 belonging ports are now only built, if the port is enabled.
276 * support/regression/*: all output is written in directory gen, because
277 the fwk and ports directories don't livet in the build tree using vpath
279 * doc/sdccman.lyx: renamed --disable-device-lib-build to
280 --disable-device-lib, added --enable-doc, added section VPATH
282 * sim/ucsim/configure.in,
283 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
284 z80 are enabled by default
286 2006-04-24 Raphael Neider <rneider AT web.de>
288 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
289 to config word, "pic14_"-prefixed some extern functions
290 (pic14_emitConfigWord): emit __config directive(s) if assignment to
291 config word has been found
292 * src/pic/device.h: added prototypes
293 * src/pic/pcode.c: added "pic14_"-prefix where needed
294 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
296 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
298 (pic14emitRegularMap): ignore config words,
299 (pic14createInterruptVect): moved generating __config directives away

557 implemented patch 1120823 Thanks to Willy De la Court (normal
558 interrupts need an interrupt number now if they are made critical),
559 and enabled nesting of critical functions though not for gbz80
560 (genCritical, genEndCritical): added functions
561 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
562 * src/z80/mappings.i: added "ei" to all mappings

567 submitted by the Debian SDCC maintainer Aurelien Jarno:
568 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
569 archive with gcc 4.1 on mips and wrote the patch"
571 2006-03-16 Raphael Neider <rneider AT web.de>
573 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
574 the left operand is shorter than the result (c* = lit-c* + int),
576 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
579 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
581 * src/.version: increased version number to 2.5.5
582 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
583 linking is done manually in pic16 port's _linkEdit,
584 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
585 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
586 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
587 allocate asmop as AOP_ACC,
588 (aopForRemat): added parameter 'bool result' in function declaration,
589 (pic16_aopGet): return AOP_ACC when accessing WREG,

601 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
602 call to allocReg, not by manually allocating a new one,
603 (pic16_assignRegisters): now before going through the register
604 allocating functions mark all registers as free. This eliminates some
605 side effects resulting from peephole parser done earlier in the backbone
607 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
609 * src/SDCCicode.c (geniCodeLogic),

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

3039 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3041 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
3044 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3046 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
3047 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3049 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3051 * device/lib/printf_large.c: removed inline assembly for portability and
3052 readability. Use printf_fast if speed or size are more important.
3053 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3054 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3056 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3058 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3059 prevent compiler warning
3061 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3063 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3064 moved to level 0 and declared as static. Also they are explicit
3065 placed in access bank. This was necessery because some times they
3066 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3067 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3068 optimizations. Currently only compare to unsigned char is implemented,
3069 * src/pic16/gen.c: added fReturnIdx array,
3070 * (struct resolvedIfx) is moved to gen.h and made public,
3071 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3072 * (aopForSym): added an optimization to directly store in stack of
3073 the operand of a SEND iCode,
3074 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3075 but as registers instead (AOP_REG) using the fReturnIdx array,
3076 * (pic16_freeAsmop): remove the freed register from the
3077 _G.sregsAlloc field,
3078 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3079 a compare of 'WREG',
3080 * (pic16_popGetTempRegCond): changed function prototype, now
3081 function takes also a bitVector argument v which holds the current
3082 set of registers that are allocated for stack access by aopForSym,
3083 registers allocated in aopForSym for accessing stack symbols are not
3084 any more part of the functions usedRegs field,
3085 * (genCall): some times aopOp is called for a stack variable to be
3086 send, aopForSym might perform the push, if this is true make sure
3087 that genCall doesn't push the variable twice by testing _G.resDirect,
3088 * (genFunction): changed testing for unspecified interrupt number
3089 from 256 to INTNO_UNSPEC,
3090 * modified selection scheme of frame pointer generation. Previously
3091 if function did use local registers a frame pointer was generated,
3092 now a frame pointer is generated only if function has arguments
3093 (that need PLUSW2 register access), or has stack arguments, or the
3094 compiler is not instructed to omit the frame pointer,
3095 * (genEndFunction): before restoring local registers that were saved
3096 in the function preamble, also restore the registers that *might*
3097 have been allocated for stack access,
3098 * (genRet): removed some old comments,
3099 * (genCmp, the active (RN's) version): added a call to the
3100 pic16_genCmp_special function to perform the compare with a more
3101 robust and optimized way,
3102 * (genInline): a feature has been added in inline code generation,
3103 which allows a wildcard variable substitution when writing inline
3104 assembly. Code is incomplete and experimental therefore undocumented,
3105 * (genCast): changed order of aopOp for result and right to allow
3106 aopForSym to directly load the result if possible,
3107 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3108 perform an optimized compare on some selected special occasions,
3109 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3110 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3111 generate an IVT any more,
3112 * src/pic16/main.c (pic16_optionsTable): added command line option
3114 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3115 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3117 * src/pic16/NOTES: Raphael Neider added in list of active developers
3118 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3119 jumptable_end to prevent bug #,
3120 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3121 inCond and outCond fields,
3122 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3123 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3124 turn off register spilling,
3125 * (packRegsForOneUse): synced with other ports' versions although it
3126 is not used currently,
3127 * (pic16_packRegisters): added an optimization while reading
3128 structure bitfields, some registers may be saved (malloc code is
3129 decreased by 80 bytes)
3131 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3133 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3134 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3135 this can be optimized more?
3137 2005-03-10 Raphael Neider <rneider AT web.de>
3139 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3140 genNearPointerGet): (hopefully) fixed access to bitfields via
3141 pointers (p->bitN = x; and x = p->bitN; failed)
3143 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3466 pic16_framepnt_*, pic16_stack_*, pic1_frame_* pointer variables to
3467 access stack and frame pointers. They are initially assigned to
3468 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
3469 accessing SFRs. Updated all occurences of modification of stack or
3470 frame pointer in gen.c and pcode.c,
3471 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with

3776 generated for switch statements. For now you need to set the
3777 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3778 Now 4 algorithms for mcs51 jumptable generation are used:
3779 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3813 * added libc directory. The current version of LibC contains string
3814 functions, ctype functions and macros and some functions of the
3815 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3816 be extensively tested in the future. Standard disclaimer here.

3830 * (genCmp): experimental code for new genCmp which uses PIC18's
3831 special compare&skip instructions. Initial tests fail some times
3832 with variables grater than 1 byte in size, so new code is disabled,
3833 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3835 * (genCast): began a fix to optimize the casting of a bit to another
3836 bit, now assigning a bitfield to another bitfield will fail, sorry,

3850 registers when it shouldn't,
3851 * src/pic16/ralloc.c (allocReg): add preliminary support for
3852 supporting a limited set of temporary registers,
3854 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6861 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6862 loaded with the linker search paths (-L arguments) and the libraries
6863 to be linked with the current source (-l arguments). Changes
6864 currently will affect only the pic16 port.
6865 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6866 include path the port specific paths and port specific libraries,
6867 * gplink command now contains the $3 argument,
6868 * src/pic16/device.h,
6869 * src/pic16/device.c,: structure PIC_device is made public and

6885 Documenting changes from previous commits.
6886 * configure.in (version 1.56),
6887 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6888 when generating output files to configure the pic16 library,
6889 but now I've commented it out, since gputils aren't installed in the
6890 SF compile farm, so library won't compile
6892 * device/lib/Makefile.in (version 1.56): initially I've added in
6893 target 'all' the prerequestive 'model-pic16' so it compiled the
6894 pic16 library, but now I've commented it out for the same reasons
6896 * added targets 'model-pic16' and 'objects-pic16' to compile the
6898 * added target 'port-specific-objects-pic16' to handle the
6899 generated libraries and copy them into the build/ directory
6900 * added target 'clean-intermediate-pic16' to clean intermediate
6901 files into pic16 directory
6902 * in target 'installdirs' added line to create directory pic16 in

6906 added lines to copy all header files to installation path,
6907 * in target 'installdirs' added line create directory for pic16
6908 headers in the installation path

6924 option so that it actually works. Made it specific to the z80, since
6925 the gbz80 doesn't have these kinds of I/O ports.
6927 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7036 UPPER for immediate operands,
7037 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7039 * src/pic16/peeph.def: all peepholes with movff are commented out,
7040 because there is a problem in the pcode peep optimizer,
7041 * src/pic16/ralloc.c: the register allocator can now reuse local
7042 function symbols for another function. This saves register usage.
7043 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7045 Added file src/pic16/NOTES with information about program writing on
7046 the current port version.

7151 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7153 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7154 (default behaviour).
7156 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7158 A python script to validate compiler diagnostic messages. It can be
7159 used to verify that sdcc complains about bad c source code and
7160 gives a good location of the error.
7161 * support/valdiag/Makefile,
7162 * support/valdiag/valdiag.py,
7163 * support/valdiag/tests/*

7180 Bug reported from Jesus Calvino-Fraga
7182 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7184 * sdcc.spec: updated
7185 * device/include/Makefile.in: don't install CVS directories
7186 * device/lib/Makefile.in: added removal of CVS directories after install
7187 * doc/Makefile: fixed install, added local_icons
7188 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7189 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7190 * src/ds390/gen.c (genRightShift): fixed bug #870788
7191 * src/SDCCast.c (decorateType): fixed bug #870781
7193 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7195 PIC16 port related changes:
7196 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7197 added variable stackPos,
7199 * gen.c: genCall, assignResultValue: added support for
7200 pushing/retrieving function parameters to/from stack,
7201 genFunction,genEndFunction: setup stack frame for the
7203 genAddrOf: will be changed according to bug 863624
7205 * added files genutils.c and genutils.h which contain gen*
7206 debugged and optimised functions extracted from gen.c
7208 * glue.c: added variable 'externs' which holds extern symbols,
7209 pic16emitRegularMap: is modified to properly handle relocatable
7210 symbols under the new scheme,
7211 pic16createInterruptVect: is modified
7212 pic16printPublics: is modified to emit 'global' assembler directives,
7213 added pic16_printExterns to print extern symbols,
7214 pic16glue: initializes stack/frame pointer in the beginning of
7215 the assembly output. Temporary hack, will be corrected later,
7216 because gplink yet does not support stack and SDCC does not
7217 yet support a type of crt0.o object to create the final binary.
7219 * Removed many lines that contain 8051 legacy code.
7220 * The code is finally placed under a 'code' directive.
7221 * Added port specific options.
7223 * _process_pragma: simplified since now we do not need *special*
7224 include file to define SFR registers. But a separate header
7225 will be needed. This will be developed later.
7226 * _pic16_parseOptions: added, parses port specific options:
7227 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7228 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7229 --preplace-udata-with=
7231 * _pic16_setDefaultOptions: modified to initialize section names,
7232 but hack is temporarly out of order since it needs improvement.
7233 * _pic16_genAssemblerPreamble: configuration words are emitted by
7234 their address instead of their name. This part is incomplete and
7235 supports only the 18Fxx2 devices. Other devices will emit an error
7236 during assembly since they do not contain the same set of config
7238 * _pic16_genIVT: is modified,
7240 * pcode.c: added definitions for some hardware registers that are needed
7242 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7243 All PCI entries are updated. Now LFSR is supported.
7244 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7245 * added pic16_newpCodeOpLit2 to support instructions with
7246 two literal arguments
7247 * pic16_pCode2str: corrected code that emits assembler instructions
7248 with two literal operands and those that have an access bit modifier
7249 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7250 this fixes a bug which caused some labels to be lost, when an
7251 assembler directive was added, i.e. banksel,
7252 * pic16_FixRegisterBanking: improved logic that causes the insertion
7254 * InlineFunction: functions that are called once, are not any more
7255 inlined. This can be a port option in the future,
7257 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7259 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7260 hold the corresponding uninitialized symbols,
7261 * pic16_allocProcessorRegister: registers have explicit marked the
7263 * pic16_allocInternalRegister: registers are explicit marked as
7265 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7266 processing list, so bit registers were lost,
7269 * ralloc.h: added field 'accessBank' and original symbol operand
7270 in register definition,
7271 * removed the field isMapped from register definition,
7273 ** Several functions have been removed from various sources:
7274 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7275 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7276 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7277 pic16_assignRelocatableRegisters
7279 ** others have been introduced:
7280 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7281 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7283 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7285 * support/scripts/inc2h.pl: changed definition of BIT_AT
7286 to emit 'sbit at' instead of 'bit at'. This was a request.
7288 PIC16 port related preliminary changes:
7289 * gen.c: prefixed function popRegFromString with
7290 pic16_ and all references to it corrected
7291 * pcode.c: all pic16_pc_* hardware registers prefixed
7292 with underscore (_),
7293 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7294 * ralloc.c: newReg(): when register is REG_SFR then
7295 set address to rIdx,
7296 pic16_allocProcessorRegister(): marks register wasUsed=0
7297 pic16_writeUsedRegs(): added a call to assign processor
7298 registers via pic16_assignFixedRegisters
7300 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7302 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7303 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7304 variables in unused register banks. Also the SSEG is placed
7305 wherever there is enough space for it, and IDATA can be anywhere
7306 in internal RAM. For now compile using -Wl-Y[stack_size].
7307 The mem file is different for this option as well, since it
7308 makes no sense of talking about DSEG lenght.
7310 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7312 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7313 in certain cases, e.g. when ROM assignment, patch provided
7314 from Albert den Haan.
7316 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7459 * src/mcs51/peephole.def,
7460 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

8202 support for standard C idiom of memory mapped variables; for
8203 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8204 to xdata int at 0x1234 tempvar = 1.
8205 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8206 provided by Akiya ISHIDA

8222 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8224 Fixed bug #621531 (const & volatile confusion in the type chain).
8225 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

8317 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8318 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8319 fetching of the pointer
8320 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8321 copied from genNearPointerSet()
8322 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8323 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8324 If they pop r0/r1 they must be called in the opposite order than aopOp().

8337 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8339 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8340 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8341 type for bits was changed. It resulted in bit variables becoming
8342 global, which is not permitted in PIC 14 assembly output.
8344 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8346 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8359 A few small changes that speed up the peephole optimizer.
8363 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8365 Try to make the peephole optimizer smarter by maintaining
8366 an association between the assembly source code and the
8367 iCodes that originated them. Put this information to use
8368 with a new peephole rule condition "notVolatile" so that
8369 the rules can be aggressive yet still safe.
8374 * src/mcs51/peeph.def
8376 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8380 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8381 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8382 if the left or right operand symbols have the accuse flag set.
8384 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8386 Changed the type of the result of the ! (NOT) operator to char;
8387 previously it returned the same type as the source. This allows
8388 us to eliminate all the genFloatNot functions (all of its target
8389 implementations were very buggy) since !float can use the same
8392 * src/SDCCicode.c (ast2iCode): ! returns char

8399 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8401 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8402 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8403 during interrupts. Ensure WSAVE is located at a shared bank address.
8404 2. Fixed page selection in some places
8405 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8406 the registers name strings.
8407 4. Fixed "signed / unsigned compare" compiler warnings.
8408 5. The PIC port manages its own allocation of the general purpose
8409 registers, but makes no attempt to reuse them. As a result when
8410 compiling it soon runs out of general purpose registers. Some
8411 additional code was added to the files pcode.c and device.c to walk
8412 through the function call tree and rename the registers so that they
8422 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8423 genPlus() & genMinus() when the result is the same as left or right

8429 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8431 Made bitfield a distinct type from bit so that bitfields
8432 convert as per ANSI C and bits retain their traditional
8433 boolean style behaviour. Implemented bitfield support in
8441 * src/ds390/gen.c: bit v bitfield split
8442 * src/z80/gen.c: New support for bitfields
8443 * support/regression/tests/bitfields.c: reenabled z80,
8446 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8448 Rules 246.x, 247.x relate to bitfields, the others speed up
8449 access to xdata mapped I/O devices.
8451 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8453 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8455 Cleaned up genPackBits and genUnpackBits and added two helper
8456 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8457 for literal assignments in genPackBits (thanks to Frieder for
8463 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8465 Fixed bug #748310 (pointer to function type mishandled when the
8466 function name is omitted). Also fixed a SIGSEGV when a function
8467 attribute (reentrant, etc) is used on a non-function or on a
8468 function but misplaced before the parameter list.
8470 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8472 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8473 * support/Util/SDCCerr.h,
8474 * support/Util/SDCCerr.c: Added func attr misuse error msg

8495 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8497 Made the constant following the "interrupt" keyword optional. If
8498 omitted, the function will not automatically be given an entry
8499 in the interrupt vector table (similar to #pragma NOIV, but
8500 less syntacticly kludgy). The interrupt number is also now
8501 range checked. Also fixed a bug in the high order bit example

8515 * src/SDCCicode.c (operandOperation): rewritten some ops
8516 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8517 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8519 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8520 be re-activated by defining REDUCE_LITERALS)
8521 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8522 unsigned, but are signed by default
8523 * src/SDCCval.c (constVal): rearranged
8524 * src/SDCCval.c (valMod): preliminary fix
8525 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9031 added if/endif conditional macros to remove options help
9032 messages from optionsTable when a port is not configured, added
9033 support for the PIc16 port in the ports table, when executing
9034 the compiler with no port specified on command line, a default
9035 port is selected with the new macro DEFAULT_PORT which is
9036 defined in port.h, in setDefaultOptions() linkOptions is removed
9037 from initialization assignment, since now it is a set,
9038 parseCmdLine uses setParseWithComma for linkOptions, in
9039 linkEdit() linkOptions are accessed with new function indexSet()
9040 which returns the i'th item of a set variable. See SDCCset.c, in
9041 linkEdit() when calling buildCmdLine(), added linkOptions as
9042 last argument. Now users can pass arguments to gplink via the
9043 -Wl option, main() uses pic16glue() to glue up pic16 programs

9057 gpasm complaining and test the linkage with gplink, _linkCmd and
9058 _asmCmd changed to be more gplink and gpasm friendly
9059 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9060 produced an error when parsed, peep rule 12 is added to utilize
9061 movff, but it is commented out since the pCode does not support
9062 yet a command with 2 address arguments
9064 2003-05-18 <johan AT balder>
9066 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10125 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10127 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10129 * in \sdcc\as\mcs51\ changed these files in order to create an
10130 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10131 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10132 following files to include the previous two files: aslink.dsp,
10133 Makefile.aslink, Makefile.bcc, and Makefile.in.
10135 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10136 .adb instead of .cdb
10138 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10140 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10141 value from option --iram-size.
10143 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10145 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10148 2002-09-18 <wiml AT hhhh.org>
10150 * SDCClrange.h: exposed setFromRange() and setToRange()
10151 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10152 packRegsForAccUse() (bug 542397)
10153 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10154 multiple times and emitting the fetch operations more than once
10155 added aopGetUsesAcc() function to allow binary operators to
10156 fetch their operands in the correct order; made genMinus() emit
10157 compact code for X = LITERAL - Y
10159 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10160 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10161 sprintf() in line 1267.
10163 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10164 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10167 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10168 Changes to aslink (All the changes are marked with 'JCF'):
10170 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10173 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10174 area BSEG. Also moves, if possible, the DATA area down into the internal
10175 ram so more space is available.
10177 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10180 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10181 not bytes. Function summary() which creates a memory usage summary
10182 file with extension .mem. Reports of overlaping stack and small stack
10183 size. If the space for the stack is less than 16 bytes aslink trows a
10186 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10187 the 8051. Option 'y' for memory summary output file.
10189 Changes to sdcc (All the changes are marked with 'JCF'):
10191 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10193 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10194 overlaying area for it (uses RegBankUsed[4]).
10196 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10197 bank zero as used by default. By default aslink locates the stack
10198 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10199 the creation of the .mem file. Delegates the allocation of data area
10200 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10201 the begining of the stack area to aslink.
10203 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10204 glue() in SDCCglue.c creates an area for it.
10206 2002-09-03 Borut Razem <borut.razem AT siol.net>
10207 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10208 sdcc/src/pic/glue.c:
10209 introduced atexit() handler for teporay files removal in case of
10210 errors, assertions, ...
10212 2002-08-29 Borut Razem <borut.razem AT siol.net>
10213 * sdcc/support/cpp2/auto-host_vc_in.h:
10214 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10215 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10216 Maybe there is a similar problem with BORLANDC? It should be checked!
10218 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10219 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10220 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10221 was not executed, and the compiler (cl) launched a warning:
10222 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10224 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10225 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10227 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10228 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10230 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10231 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10232 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10233 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10234 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10235 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10236 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10237 - added Release configuration in VS projects
10238 - review of compiler an linker options
10239 - VC .exe files are generated in bin_vc directory, not to interfere
10240 with binaries generated from other projects (cygwin, mingw, bcc ...)
10242 * sdcc/src/yacc.dsp: added
10244 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10245 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10246 and insert the version number definitions from .version
10248 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10250 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10251 added - genarate auto-host.h using auto-host_vc_in.h as template
10254 removed from CVS, generated automatically
10256 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10257 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10259 2002-08-11 Borut Razem <borut.razem AT siol.net>
10260 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10262 2002-08-10 Borut Razem <borut.razem AT siol.net>
10263 * src/SDCCmain.c (main):
10264 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10265 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10266 The consequence was that some temporary files were not removed.
10269 unification of code in functions tempfilename() and tempfile():
10270 function tempnam() is defined in Visual Studio 6.0 and .NET
10272 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10274 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10275 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10276 - removed compiler command line option /WX: Treats all warnings as errors
10277 - update a list of source files, included into the project
10279 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10280 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10281 changed project type to Generic Project so that can be correcly converted to VS.NET project
10283 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10285 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10287 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10289 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10290 added return 0 statements after assert() to make compiler happy
10292 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10293 added newline in the def file to keep MSC compiler satisfied
10295 * sdcc/src/z80/gen.c:
10296 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10297 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10298 - solved MSC error in function aopDump()
10300 * sdcc_vc.h: define PREFIX as "\\sdcc"
10302 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10303 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10306 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10307 - Rewrote the register banking algorithm.
10308 - Added pCode live-range analysis to registers (for now, only non-used and
10309 singly-used registers optimized away)
10311 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10313 * 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.

10338 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10340 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10342 2002-03-28 Johan Knol <johan AT balder>
10344 * src/SDCCval.c: fixed bug #532436
10346 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10348 Added "char *Processor" field to the port structure.
10351 Added -p option. Allows port dependent processor to be specified.
10354 Initialized the new field char *Processor field to NULL in all ports
10357 Compiler generated registers for interrupt context saving
10358 were not getting allocated.
10360 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10363 Fixed left shift. Will promote the left side of a left shift
10364 if a) left shifting more than size of operand or b) when assigned
10365 to something size > size of left side
10367 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10369 tons of changes. Register allocation has been
10370 rewritten. Added customization for the various PICs. Flow
10371 analysis is restructured. ...
10373 * src/pic/device.h:
10376 * src/pic/device.c:
10377 Added. device.c is a PIC port hack to accomodate variations
10380 2002-03-13 Michael Hope <michaelh AT vroom>
10382 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10384 2002-03-04 johanknol <johanknol AT manik>
10386 * /src/SDCCval.c: fixed
10388 const unsigned char arr[][2] = { { 0, 1 } };
10389 t18.c:1: error: Initializer element is not constant
10391 2002-03-04 bela <bela AT manik>
