1364 pic14_getSharedStack): NEW, evaluate the memRange entries to locate
1365 a sharebank, use a non-shared bank for the stack if none available

1367 added prototypes for above functions
1368 * src/pic/ralloc.c (initStack): handle shared and banked stacks,
1369 (typeRegWithIdx): accept fixed and unfixed stack registers

1374 possibly aliased bank of memory, like 16f84
1375 * src/pic/glue.c (pic14_constructAbsMap): back to udata_ovr, as some

1388 genRightShift): fixed bug with non-constant bit shift stored to
1389 a volatile result (SF Open Discussion forum thread #1616749).
1390 Single byte case is not yet optimized.

3293 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
3295 Enabled VPATH feature: changed nearly all Makefiles (149 files).
3296 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
3298 One basic decision: e.g. src/clean.mk includes further files. In order
3299 to make this work there are two solutions:
3300 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
3301 run configure on them. This way they can use
3302 'include $(srcdir)/port-clean.mk'
3303 - always include clean.mk by the Makefile at the same level. To avoid
3304 that `make clean` tries to include and build Makefile.dep the
3305 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
3306 implemented, because now even `make uninstall` doesn't create
3307 Makefile.in. clean.mk could be eliminated by pasting it in
3310 * debugger/mcs51/Makefile.in: build own objects from library sources
3311 (SLIB, SDCC) in current directory
3313 * configure, configure.in: renamed --disable-device-lib-build in
3314 --disable-device-lib; added --enable-doc, the required tools are
3315 searched by configure; added result message; the toolchain for the
3316 belonging ports are now only built, if the port is enabled.
3318 * support/regression/*: all output is written in directory gen, because
3319 the fwk and ports directories don't livet in the build tree using vpath
3321 * doc/sdccman.lyx: renamed --disable-device-lib-build to
3322 --disable-device-lib, added --enable-doc, added section VPATH
3324 * sim/ucsim/configure.in,
3325 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
3326 z80 are enabled by default
3328 2006-04-24 Raphael Neider <rneider AT web.de>
3330 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
3331 to config word, "pic14_"-prefixed some extern functions
3332 (pic14_emitConfigWord): emit __config directive(s) if assignment to
3333 config word has been found
3334 * src/pic/device.h: added prototypes
3335 * src/pic/pcode.c: added "pic14_"-prefix where needed
3336 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
3338 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

3341 (pic14createInterruptVect): moved generating __config directives away

3599 implemented patch 1120823 Thanks to Willy De la Court (normal
3600 interrupts need an interrupt number now if they are made critical),
3601 and enabled nesting of critical functions though not for gbz80
3602 (genCritical, genEndCritical): added functions
3603 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
3604 * src/z80/mappings.i: added "ei" to all mappings

3613 2006-03-16 Raphael Neider <rneider AT web.de>
3615 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
3616 the left operand is shorter than the result (c* = lit-c* + int),
3618 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
3621 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3623 * src/.version: increased version number to 2.5.5
3624 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
3625 linking is done manually in pic16 port's _linkEdit,
3626 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
3627 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
3628 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
3629 allocate asmop as AOP_ACC,
3630 (aopForRemat): added parameter 'bool result' in function declaration,
3631 (pic16_aopGet): return AOP_ACC when accessing WREG,
3632 (pic16_popGetTempReg): minor modification,
3633 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
3634 'pic16_allocWithIdx',

3641 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
3643 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
3644 call to allocReg, not by manually allocating a new one,
3645 (pic16_assignRegisters): now before going through the register
3646 allocating functions mark all registers as free. This eliminates some
3647 side effects resulting from peephole parser done earlier in the backbone
3649 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
3651 * src/SDCCicode.c (geniCodeLogic),

3671 (aopForSym, aopOp): increment asmop.allocated if reused,
3672 (freeAsmop): decrement asmop.allocated and check for zero instead of
3674 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
3675 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
3676 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

3699 2006-03-06 Borut Razem <borut.razem AT siol.net>
3701 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
3702 made the linker quiet
3704 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
3706 * src/pic16/gen.c (genPcall): fixed bug #1443644
3707 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
3708 which dumps before the function entry point a data byte which represents
3709 the number of the local variables used by the specified function, added
3710 'xinst' for initial support for Extended Instruction Support,
3711 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
3712 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
3713 port->fun_prefix anymore (may change later),
3714 (genFunction, genEndFunction): do not store/restore local registers for
3715 _main (this should take care the --main-return command line option in
3717 (genOr): removed some legacy pic-port instructions,
3718 * src/pic16/genarith.c (genAddLit): re-enabled old code because
3719 performing operations with SFR's causes data to be written more than
3720 once to each SFR. Perhaps SFRs should be handled in special cases...
3721 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
3723 * src/pic16/main.c (_process_pragma): stack bound checking did not take
3724 into account for stack starting position,
3725 (struct OPTIONS pic16_optionsTable): added command line argument
3726 --extended or -y for Extended Instruction Support,
3727 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
3728 (deassignLRs): *** perhaps the most important change, old 'for' code
3729 (commented out for reference), didn't account for some registers which
3730 were left marked 'not free' after a pointer operation. The change
3731 reduces register usage a lot in some cases
3733 2006-03-04 Borut Razem <borut.razem AT siol.net>

6004 * src/SDCCglobal.h (struct options),
6006 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
6007 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
6008 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
6009 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
6010 always available in leading double underscore form. The C99 support is
6011 mostly missing, but it's a start.
6012 * support/regression/tests/bug-227710.c: fixed nonconforming use of
6013 reserved identifier "__data".
6015 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

6059 immedDom() returning wrong block; probably fixes bug #1160833)
6061 2005-03-20 Borut Razem <borut.razem AT siol.net>
6063 * support/scripts/inc2h.pl: WIN32 port
6065 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
6067 * device/lib/makefile.in: added abs.c and labs.c
6069 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
6071 * device/include/stdint.h: added
6072 * device/lib/abs.c: added
6073 * device/lib/labs.c: added
6074 * device/include/stdlib.h: added abs() and labs() prototypes

6089 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
6091 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
6093 * device/lib/printf_large.c: removed inline assembly for portability and
6094 readability. Use printf_fast if speed or size are more important.
6095 * src/pic16/gen.c: removed conditions around use of DEBUGpc
6096 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
6098 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
6100 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
6101 prevent compiler warning
6103 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
6105 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
6106 moved to level 0 and declared as static. Also they are explicit
6107 placed in access bank. This was necessery because some times they
6108 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
6109 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
6110 optimizations. Currently only compare to unsigned char is implemented,
6111 * src/pic16/gen.c: added fReturnIdx array,
6112 * (struct resolvedIfx) is moved to gen.h and made public,
6113 * (struct _G): added sregsAlloc and sregsAllocSet fields,
6114 * (aopForSym): added an optimization to directly store in stack of
6115 the operand of a SEND iCode,
6116 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
6117 but as registers instead (AOP_REG) using the fReturnIdx array,
6118 * (pic16_freeAsmop): remove the freed register from the
6119 _G.sregsAlloc field,
6120 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
6121 a compare of 'WREG',
6122 * (pic16_popGetTempRegCond): changed function prototype, now
6123 function takes also a bitVector argument v which holds the current
6124 set of registers that are allocated for stack access by aopForSym,
6125 registers allocated in aopForSym for accessing stack symbols are not
6126 any more part of the functions usedRegs field,
6127 * (genCall): some times aopOp is called for a stack variable to be
6128 send, aopForSym might perform the push, if this is true make sure
6129 that genCall doesn't push the variable twice by testing _G.resDirect,
6130 * (genFunction): changed testing for unspecified interrupt number
6131 from 256 to INTNO_UNSPEC,
6132 * modified selection scheme of frame pointer generation. Previously
6133 if function did use local registers a frame pointer was generated,
6134 now a frame pointer is generated only if function has arguments
6135 (that need PLUSW2 register access), or has stack arguments, or the
6136 compiler is not instructed to omit the frame pointer,
6137 * (genEndFunction): before restoring local registers that were saved
6138 in the function preamble, also restore the registers that *might*
6139 have been allocated for stack access,
6140 * (genRet): removed some old comments,
6141 * (genCmp, the active (RN's) version): added a call to the
6142 pic16_genCmp_special function to perform the compare with a more
6143 robust and optimized way,
6144 * (genInline): a feature has been added in inline code generation,
6145 which allows a wildcard variable substitution when writing inline
6146 assembly. Code is incomplete and experimental therefore undocumented,
6147 * (genCast): changed order of aopOp for result and right to allow
6148 aopForSym to directly load the result if possible,
6149 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
6150 perform an optimized compare on some selected special occasions,
6151 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
6152 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
6153 generate an IVT any more,
6154 * src/pic16/main.c (pic16_optionsTable): added command line option
6156 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
6157 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
6159 * src/pic16/NOTES: Raphael Neider added in list of active developers
6160 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
6161 jumptable_end to prevent bug #,
6162 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
6163 inCond and outCond fields,
6164 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
6165 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
6166 turn off register spilling,
6167 * (packRegsForOneUse): synced with other ports' versions although it
6168 is not used currently,
6169 * (pic16_packRegisters): added an optimization while reading
6170 structure bitfields, some registers may be saved (malloc code is
6171 decreased by 80 bytes)
6173 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
6175 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
6176 left is a bitfield, if yes, then don't optimize assignment. Perhaps
6177 this can be optimized more?
6179 2005-03-10 Raphael Neider <rneider AT web.de>
6181 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
6182 genNearPointerGet): (hopefully) fixed access to bitfields via
6183 pointers (p->bitN = x; and x = p->bitN; failed)
6185 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

6373 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
6374 this might fix SIGSEGVs on MinGW...
6375 * src/SDCCopt.c (killDeadCode): restored original behaviour
6376 (volatile operands might get thrown away though)
6378 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

6457 * src/SDCCglobl.h: ensure that PATH_MAX >= 2048 to guarantee
6458 cmdLine buffers (used when calling sdcpp...) are large enough
6459 (MAX_PATH=256 truncates arguments leading to system halts when
6461 * src/pic16/gen.c (pic16_sameRegs): relaxed size criterion
6462 * (genUminus): rewritten to for efficiency
6463 * (genNearPointer[GS]et): enforce reloading of FSR0 (was still
6464 used uninitialized in some cases)
6465 * (genCast): upcasting a 16bit int to a 24bit GPOINTER may not
6466 copy the third byte from the int -- now assumes 0x80 (data memory)
6467 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
6468 operands (genAddLit expects the iCode's operands to swapped as
6469 well), fixed leftover bytes (crashed for short left operands)
6470 * (pic16_genMinusDec): performance improvements, removed false
6472 * (pic16_genMinus): fixed to cope with differently sized operands
6473 * src/pic16/glue.c (pic16_glue): added new banksel optimization
6475 * src/pic16/pcode.c: implemented (first phase of) banksel optimization
6476 * src/pic16/graph.[ch]: implementation of directed graphs, used by
6477 new banksel optimization

6479 analysis for temporary registers (segfaults...)
6480 * src/pic16/peeph.def: added rule
6482 2005-01-18 Vangelis Rokas <vrokas AT otenet.gr>

6485 which converts a float number to its ASCII representation
6486 * device/lib/pic16/libc/utils/cnvfrac.S,cnvint.S: support
6487 functions to convert the fractional and integer part of a float to ASCII,
6488 * device/lib/pic16/libc/stdlib/(calloc.c,free.c, malloc.c,

6500 * src/pic16/ralloc.c (decodeOp): removed static declaration and
6501 renamed to pic16_decodeOp,

6503 sequences that test a single bit for 1/0
6505 2005-01-12 Vangelis Rokas <vrokas AT otenet.gr>
6507 * src/pic16/pcode.[ch]: introduced pic16_stackpnt_*,
6508 pic16_framepnt_*, pic16_stack_*, pic1_frame_* pointer variables to
6509 access stack and frame pointers. They are initially assigned to
6510 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
6511 accessing SFRs. Updated all occurences of modification of stack or
6512 frame pointer in gen.c and pcode.c,
6513 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
6514 assigning of a literal value to pointers,
6515 * src/pic16/main.c (pic16_finiliseOptions): set pre-processor define
6516 flag STACK_MODEL_SMALL or STACK_MODEL_LARGE according to the model

6538 2005-01-04 Raphael Neider <rneider AT web.de>
6540 * src/pic16/gen.c (genIfxJump): fixed inverted skips on CARRY
6541 * (genIfx): fixed (?) read from uninitialized SPIL_LOC (now assumes CARRY
6542 to hold the condition bit)
6543 * added new version of genCmp (old code available via #define)
6544 * added new version of genShiftLeft/genShiftRight in a generic
6545 way, now supports shifting by negative values

6557 from Raphael Neider,
6558 * src/pic16/pcode.c (pic16_newpCodeOpLit): removed casting to char
6559 for 8-bit literals. This fixes some literal operands which are sign
6560 extended to 16-bits ints when instruction needs only 8-bits.

6817 Adding support for replacing ljmps with sjmps in jumptables
6818 generated for switch statements. For now you need to set the
6819 environment variable SDCC_SJMP_JUMPTABLE to enable this.
6820 Now 4 algorithms for mcs51 jumptable generation are used:
6821 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
6822 addresses loaded pc-relative for up to 112 cases and stack-pushing
6823 target addresses loaded with offset from dptr for up to 256 cases.
6825 * src/SDCCpeeph.c: added peephole conditional labelJTInRange

6849 Large cummulative patch for pic16 port.
6850 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
6851 to call when a stack overflow occurs,
6852 * (malloc.h): added CVS Id tag,
6853 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
6855 * added libc directory. The current version of LibC contains string
6856 functions, ctype functions and macros and some functions of the
6857 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
6858 be extensively tested in the future. Standard disclaimer here.
6859 Library is not automatically build yet. But one can build it by
6860 invoking 'make' inside the libc directory.
6861 * added ADC library under libio. Preliminary version yet.
6863 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
6864 * src/pic16/gen.c (aopForRemat): asmop size is filled by
6865 aopForRemat() now and not by pic16_aopOp(),
6866 * (pic16_popGetTempReg): removed warning messgae when allocating
6867 temporary registers, its a buggy feature and will be removed,
6868 * (pic16_popGet): set register instance field in AOP_CRY,
6869 * (pic16_outBitC): fixed for results in size greater than 1,
6870 * (genUminusFloat): fixed for pic16, ported code from mcs51,
6871 * (pic16_storeForReturn): optimized return of 0,
6872 * (genCmp): experimental code for new genCmp which uses PIC18's
6873 special compare&skip instructions. Initial tests fail some times
6874 with variables grater than 1 byte in size, so new code is disabled,
6875 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
6877 * (genCast): began a fix to optimize the casting of a bit to another
6878 bit, now assigning a bitfield to another bitfield will fail, sorry,

9901 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
9903 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
9904 loaded with the linker search paths (-L arguments) and the libraries
9905 to be linked with the current source (-l arguments). Changes
9906 currently will affect only the pic16 port.
9907 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
9908 include path the port specific paths and port specific libraries,
9909 * gplink command now contains the $3 argument,
9910 * src/pic16/device.h,
9911 * src/pic16/device.c,: structure PIC_device is made public and
9912 renamed to PIC16_device, the same for variable Pics which is renamed

9927 Documenting changes from previous commits.
9928 * configure.in (version 1.56),
9929 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
9930 when generating output files to configure the pic16 library,
9931 but now I've commented it out, since gputils aren't installed in the
9932 SF compile farm, so library won't compile
9934 * device/lib/Makefile.in (version 1.56): initially I've added in
9935 target 'all' the prerequestive 'model-pic16' so it compiled the
9936 pic16 library, but now I've commented it out for the same reasons
9938 * added targets 'model-pic16' and 'objects-pic16' to compile the
9940 * added target 'port-specific-objects-pic16' to handle the
9941 generated libraries and copy them into the build/ directory
9942 * added target 'clean-intermediate-pic16' to clean intermediate
9943 files into pic16 directory
9944 * in target 'installdirs' added line to create directory pic16 in
9945 the installation path
9947 * device/include/Makefile.in (version 1.11): in target 'install'
9948 added lines to copy all header files to installation path,
9949 * in target 'installdirs' added line create directory for pic16
9950 headers in the installation path

9966 option so that it actually works. Made it specific to the z80, since
9967 the gbz80 doesn't have these kinds of I/O ports.
9969 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9993 Mainly changes to support compilation of the device libraries
9994 * src/pic16/device.c: stack is allocated via symbol and not
9995 via literal number. The symbol is placed in the corresponding
9996 position of the data ram
9997 * (pic16_dump_section): relocatable and absolute uninitialized
9998 data are now emitted in sorted order to reduce section naming,
9999 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
10000 weren't marked as being in the access bank,
10002 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
10004 Added portion of GNU PIC Library under the directory
10005 device/include/pic16 and device/lib/pic16. These files
10006 contain the declarations of SFRs for the PIC18Fxx2 devices.
10007 The directory is initialized via configure from toplevel.
10009 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

10034 2004-01-11 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
10036 * doc/sdccman.lyx: Moved and added some sections, small changes
10037 all over. Telling LaTeX to be less strict with word spacing
10038 to better keep the right margin. Changed some notes about
10039 maintainance of the ports in section 3.2.1 - is it OK like this?
10041 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>
10043 SDCC source changes:
10044 * src/SDCCopt.c (cntToFcall, cnvToFloatCast, cnvFromFloatCast,

10048 PIC16 PORT specific changes:
10049 * src/pic16/device.c pic16_dump_equates() added,
10050 processor registers declared internally by the port are emitted in
10051 the translation as equates,

10078 UPPER for immediate operands,
10079 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
10081 * src/pic16/peeph.def: all peepholes with movff are commented out,
10082 because there is a problem in the pcode peep optimizer,
10083 * src/pic16/ralloc.c: the register allocator can now reuse local
10084 function symbols for another function. This saves register usage.
10085 * src/pic16/ralloc.h: added flag isLocal in structure regs,
10087 Added file src/pic16/NOTES with information about program writing on
10088 the current port version.

10117 gen51Code): more efficient parameter receive for --model-large
10120 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10122 * src/ds390/main.c,

10146 devices only with SHAREBANK memory (reported from Erik Epetrich)
10147 * (pic14emitOverlay): modified to emit a commented overlay segment
10148 directive when no overlay data exist
10149 * (picglue): modified to emit uninitialized data segment
10150 according to udata_section_name
10151 * src/pic/main.c (_pic14_parseOptions): added command line
10152 options --udata-section-name=[name] to override default

10168 * doc/Makefile: fix install
10170 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10172 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
10174 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to
10175 how the function variable allocation summary is displayed; also
10176 include information about variables allocated to the overlay
10179 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10181 * as/mcs51/lkmain.c: Help about -Y option

10193 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10195 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
10196 (default behaviour).
10198 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10200 A python script to validate compiler diagnostic messages. It can be
10201 used to verify that sdcc complains about bad c source code and
10202 gives a good location of the error.
10203 * support/valdiag/Makefile,
10204 * support/valdiag/valdiag.py,
10205 * support/valdiag/tests/*
10207 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
10209 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
10210 * src/SDCCsymt.c (newEnumType),

10218 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10220 * src/common.h: added ifndef/define/endif macros
10221 around the header file.
10222 Bug reported from Jesus Calvino-Fraga
10224 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
10226 * sdcc.spec: updated

10232 * src/ds390/gen.c (genRightShift): fixed bug #870788
10233 * src/SDCCast.c (decorateType): fixed bug #870781
10235 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
10237 PIC16 port related changes:
10238 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
10239 added variable stackPos,
10241 * gen.c: genCall, assignResultValue: added support for
10242 pushing/retrieving function parameters to/from stack,
10243 genFunction,genEndFunction: setup stack frame for the
10244 generated function,
10245 genAddrOf: will be changed according to bug 863624
10247 * added files genutils.c and genutils.h which contain gen*
10248 debugged and optimised functions extracted from gen.c
10250 * glue.c: added variable 'externs' which holds extern symbols,
10251 pic16emitRegularMap: is modified to properly handle relocatable
10252 symbols under the new scheme,
10253 pic16createInterruptVect: is modified
10254 pic16printPublics: is modified to emit 'global' assembler directives,
10255 added pic16_printExterns to print extern symbols,
10256 pic16glue: initializes stack/frame pointer in the beginning of
10257 the assembly output. Temporary hack, will be corrected later,
10258 because gplink yet does not support stack and SDCC does not
10259 yet support a type of crt0.o object to create the final binary.
10261 * Removed many lines that contain 8051 legacy code.
10262 * The code is finally placed under a 'code' directive.
10263 * Added port specific options.
10265 * _process_pragma: simplified since now we do not need *special*
10266 include file to define SFR registers. But a separate header
10267 will be needed. This will be developed later.
10268 * _pic16_parseOptions: added, parses port specific options:
10269 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
10270 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
10271 --preplace-udata-with=
10273 * _pic16_setDefaultOptions: modified to initialize section names,
10274 but hack is temporarly out of order since it needs improvement.
10275 * _pic16_genAssemblerPreamble: configuration words are emitted by
10276 their address instead of their name. This part is incomplete and
10277 supports only the 18Fxx2 devices. Other devices will emit an error
10278 during assembly since they do not contain the same set of config
10280 * _pic16_genIVT: is modified,
10282 * pcode.c: added definitions for some hardware registers that are needed
10284 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
10285 All PCI entries are updated. Now LFSR is supported.
10286 * Removed pic16_pciTRIS is mentioned by mdubuc in source
10287 * added pic16_newpCodeOpLit2 to support instructions with
10288 two literal arguments
10289 * pic16_pCode2str: corrected code that emits assembler instructions
10290 with two literal operands and those that have an access bit modifier
10291 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
10292 this fixes a bug which caused some labels to be lost, when an
10293 assembler directive was added, i.e. banksel,
10294 * pic16_FixRegisterBanking: improved logic that causes the insertion
10296 * InlineFunction: functions that are called once, are not any more
10297 inlined. This can be a port option in the future,
10299 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
10301 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
10302 hold the corresponding uninitialized symbols,
10303 * pic16_allocProcessorRegister: registers have explicit marked the
10305 * pic16_allocInternalRegister: registers are explicit marked as
10307 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
10308 processing list, so bit registers were lost,
10311 * ralloc.h: added field 'accessBank' and original symbol operand
10312 in register definition,
10313 * removed the field isMapped from register definition,
10315 ** Several functions have been removed from various sources:
10316 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
10317 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
10318 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
10319 pic16_assignRelocatableRegisters
10321 ** others have been introduced:
10322 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
10323 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
10325 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
10327 * support/scripts/inc2h.pl: changed definition of BIT_AT
10328 to emit 'sbit at' instead of 'bit at'. This was a request.
10330 PIC16 port related preliminary changes:
10331 * gen.c: prefixed function popRegFromString with
10332 pic16_ and all references to it corrected
10333 * pcode.c: all pic16_pc_* hardware registers prefixed
10334 with underscore (_),
10335 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
10336 * ralloc.c: newReg(): when register is REG_SFR then
10337 set address to rIdx,
10338 pic16_allocProcessorRegister(): marks register wasUsed=0
10339 pic16_writeUsedRegs(): added a call to assign processor
10340 registers via pic16_assignFixedRegisters
10342 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10344 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
10345 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
10346 variables in unused register banks. Also the SSEG is placed
10347 wherever there is enough space for it, and IDATA can be anywhere
10348 in internal RAM. For now compile using -Wl-Y[stack_size].
10349 The mem file is different for this option as well, since it
10350 makes no sense of talking about DSEG lenght.
10352 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
10354 * src/SDCClrange.c: fixed bug 869095 that caused segfault
10355 in certain cases, e.g. when ROM assignment, patch provided
10356 from Albert den Haan.
10358 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

10601 it breaks with bitfields, extern declarations, and gcse analysis.
10602 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
10603 could be assigned through a pointer, so don't complain.

10911 not occur if the control variable is involved with a
10912 relational operator.

11405 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11407 Try to make the peephole optimizer smarter by maintaining
11408 an association between the assembly source code and the
11409 iCodes that originated them. Put this information to use
11410 with a new peephole rule condition "notVolatile" so that
11411 the rules can be aggressive yet still safe.
11416 * src/mcs51/peeph.def
11418 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11422 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
11423 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
11424 if the left or right operand symbols have the accuse flag set.
11426 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11428 Changed the type of the result of the ! (NOT) operator to char;
11429 previously it returned the same type as the source. This allows
11430 us to eliminate all the genFloatNot functions (all of its target
11431 implementations were very buggy) since !float can use the same
11434 * src/SDCCicode.c (ast2iCode): ! returns char
11435 * src/mcs51/gen.c (genNot, genNotFloat),
11436 * src/ds390/gen.c (genNot, genNotFloat),
11437 * src/z80/gen.c (genNot, genNotFloat),
11438 * src/pic/gen.c (genNot, genNotFloat),
11439 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat

11443 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
11444 1. Interrupt would not compile properly. Ensure PCLATH register is saved
11445 during interrupts. Ensure WSAVE is located at a shared bank address.
11446 2. Fixed page selection in some places
11447 3. Fixed BTFSS/C to where necessary use registers directly and not simply
11448 the registers name strings.
11449 4. Fixed "signed / unsigned compare" compiler warnings.
11450 5. The PIC port manages its own allocation of the general purpose
11451 registers, but makes no attempt to reuse them. As a result when
11452 compiling it soon runs out of general purpose registers. Some
11453 additional code was added to the files pcode.c and device.c to walk
11454 through the function call tree and rename the registers so that they
11464 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
11465 genPlus() & genMinus() when the result is the same as left or right
11467 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11469 * src/z80/gen.c (isUnsplitable, fetchPairLong): fixed bug #770454
11471 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11473 Made bitfield a distinct type from bit so that bitfields
11474 convert as per ANSI C and bits retain their traditional
11475 boolean style behaviour. Implemented bitfield support in
11483 * src/ds390/gen.c: bit v bitfield split
11484 * src/z80/gen.c: New support for bitfields
11485 * support/regression/tests/bitfields.c: reenabled z80,
11488 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
11490 Rules 246.x, 247.x relate to bitfields, the others speed up
11491 access to xdata mapped I/O devices.
11493 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
11495 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11497 Cleaned up genPackBits and genUnpackBits and added two helper
11498 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
11499 for literal assignments in genPackBits (thanks to Frieder for
11505 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11507 Fixed bug #748310 (pointer to function type mishandled when the
11508 function name is omitted). Also fixed a SIGSEGV when a function
11509 attribute (reentrant, etc) is used on a non-function or on a
11510 function but misplaced before the parameter list.
11512 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
11514 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
11515 * support/Util/SDCCerr.h,
11516 * support/Util/SDCCerr.c: Added func attr misuse error msg
11518 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
11520 Fixed bug #787649 by anonymous
11521 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
11522 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
11524 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

11537 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
11539 Made the constant following the "interrupt" keyword optional. If
11540 omitted, the function will not automatically be given an entry
11541 in the interrupt vector table (similar to #pragma NOIV, but
11542 less syntacticly kludgy). The interrupt number is also now
11543 range checked. Also fixed a bug in the high order bit example
11550 * support/Util/SDCCerr.c
11551 * support/Util/SDCCerr.h
11554 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

11557 * src/SDCCicode.c (operandOperation): rewritten some ops
11558 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
11559 * src/SDCCsymt.c (computeType): literals are handled the same way as any
11561 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
11562 be re-activated by defining REDUCE_LITERALS)
11563 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
11564 unsigned, but are signed by default
11565 * src/SDCCval.c (constVal): rearranged
11566 * src/SDCCval.c (valMod): preliminary fix
11567 * src/SDCCval.c (valCastLiteral): use TYPE_* types

11607 * src/SDCCval.c (cheapestVal, valueFromLit): use TYPE_* types
11608 * src/SDCCval.c (constVal): changed default to signed; hex and octal
11609 constants are unsigned; added recognition of "u" flag for unsigned
11610 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
11611 * src/SDCCval.c (valDiv, valMod): fixed signdness

12019 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
12020 the regression tests I'm not brave enough to enable 245.b, 245.c
12021 * doc/sdccman.lyx: added latex preamble for hyperref package.
12022 Using pdflatex this will give you a hyperlinked pdf file with

12073 added if/endif conditional macros to remove options help
12074 messages from optionsTable when a port is not configured, added
12075 support for the PIc16 port in the ports table, when executing
12076 the compiler with no port specified on command line, a default
12077 port is selected with the new macro DEFAULT_PORT which is
12078 defined in port.h, in setDefaultOptions() linkOptions is removed
12079 from initialization assignment, since now it is a set,
12080 parseCmdLine uses setParseWithComma for linkOptions, in
12081 linkEdit() linkOptions are accessed with new function indexSet()
12082 which returns the i'th item of a set variable. See SDCCset.c, in
12083 linkEdit() when calling buildCmdLine(), added linkOptions as
12084 last argument. Now users can pass arguments to gplink via the
12085 -Wl option, main() uses pic16glue() to glue up pic16 programs

12098 * src/pic16/main.c: __config directives are commented out to stop
12099 gpasm complaining and test the linkage with gplink, _linkCmd and
12100 _asmCmd changed to be more gplink and gpasm friendly
12101 * src/pic16/peeph.def: peep rule 3 is commented out, since it
12102 produced an error when parsed, peep rule 12 is added to utilize
12103 movff, but it is commented out since the pCode does not support
12104 yet a command with 2 address arguments
12106 2003-05-18 <johan AT balder>
12108 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

13233 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
13235 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
13236 overlaying area for it (uses RegBankUsed[4]).
13238 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
13239 bank zero as used by default. By default aslink locates the stack
13240 (equivalent to --stack-after-data). Pass option 'y' to aslink for
13241 the creation of the .mem file. Delegates the allocation of data area
13242 to aslink (it is not longer 0x30 by default). If --stack-loc passes
13243 the begining of the stack area to aslink.
13245 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
13246 glue() in SDCCglue.c creates an area for it.
13248 2002-09-03 Borut Razem <borut.razem AT siol.net>
13249 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
13250 sdcc/src/pic/glue.c:
13251 introduced atexit() handler for teporay files removal in case of
13252 errors, assertions, ...
13254 2002-08-29 Borut Razem <borut.razem AT siol.net>
13255 * sdcc/support/cpp2/auto-host_vc_in.h:
13256 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
13257 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
13258 Maybe there is a similar problem with BORLANDC? It should be checked!
13260 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
13261 corrected improper use of assert: the assignment to clr variable was done inside the assert.
13262 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
13263 was not executed, and the compiler (cl) launched a warning:
13264 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
13266 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
13267 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
13269 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
13270 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
13272 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13273 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
13274 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
13275 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13276 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
13277 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
13278 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
13279 - added Release configuration in VS projects
13280 - review of compiler an linker options
13281 - VC .exe files are generated in bin_vc directory, not to interfere
13282 with binaries generated from other projects (cygwin, mingw, bcc ...)
13284 * sdcc/src/yacc.dsp: added
13286 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
13287 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
13288 and insert the version number definitions from .version
13290 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
13292 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
13293 added - genarate auto-host.h using auto-host_vc_in.h as template
13296 removed from CVS, generated automatically
13298 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
13299 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
13301 2002-08-11 Borut Razem <borut.razem AT siol.net>
13302 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
13304 2002-08-10 Borut Razem <borut.razem AT siol.net>
13305 * src/SDCCmain.c (main):
13306 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
13307 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
13308 The consequence was that some temporary files were not removed.
13311 unification of code in functions tempfilename() and tempfile():
13312 function tempnam() is defined in Visual Studio 6.0 and .NET
13314 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
13316 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
13317 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
13318 - removed compiler command line option /WX: Treats all warnings as errors
13319 - update a list of source files, included into the project
13321 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
13322 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
13323 changed project type to Generic Project so that can be correcly converted to VS.NET project
13325 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
13327 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
13329 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
13331 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
13332 added return 0 statements after assert() to make compiler happy
13334 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
13335 added newline in the def file to keep MSC compiler satisfied
13337 * sdcc/src/z80/gen.c:
13338 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
13339 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
13340 - solved MSC error in function aopDump()
13342 * sdcc_vc.h: define PREFIX as "\\sdcc"
13344 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
13345 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

13393 Added -p option. Allows port dependent processor to be specified.
13396 Initialized the new field char *Processor field to NULL in all ports
13399 Compiler generated registers for interrupt context saving
13400 were not getting allocated.
13402 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>

13517 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
13519 * sdcc/src/SDCCloop.c:
13520 Previous fix was not good. basic blocks that have "break" or "return" are
13521 not really partof a loop , but live ranges used in these blocks should
13522 be live thru the entire loop, so set partOfLoop but don't add them to
13525 2002-02-21 <johan AT FRIJA>
13527 * src/SDCCcse.c: fixed bug #514308
13529 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
