480 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
482 Enabled VPATH feature: changed nearly all Makefiles (149 files).
483 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
485 One basic decision: e.g. src/clean.mk includes further files. In order
486 to make this work there are two solutions:
487 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
488 run configure on them. This way they can use
489 'include $(srcdir)/port-clean.mk'
490 - always include clean.mk by the Makefile at the same level. To avoid
491 that `make clean` tries to include and build Makefile.dep the
492 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
493 implemented, because now even `make uninstall` doesn't create
494 Makefile.in. clean.mk could be eliminated by pasting it in
497 * debugger/mcs51/Makefile.in: build own objects from library sources
498 (SLIB, SDCC) in current directory
500 * configure, configure.in: renamed --disable-device-lib-build in
501 --disable-device-lib; added --enable-doc, the required tools are
502 searched by configure; added result message; the toolchain for the
503 belonging ports are now only built, if the port is enabled.
505 * support/regression/*: all output is written in directory gen, because
506 the fwk and ports directories don't livet in the build tree using vpath
508 * doc/sdccman.lyx: renamed --disable-device-lib-build to
509 --disable-device-lib, added --enable-doc, added section VPATH
511 * sim/ucsim/configure.in,
512 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
513 z80 are enabled by default
515 2006-04-24 Raphael Neider <rneider AT web.de>
517 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
518 to config word, "pic14_"-prefixed some extern functions
519 (pic14_emitConfigWord): emit __config directive(s) if assignment to
520 config word has been found
521 * src/pic/device.h: added prototypes
522 * src/pic/pcode.c: added "pic14_"-prefix where needed

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

900 port->fun_prefix anymore (may change later),
901 (genFunction, genEndFunction): do not store/restore local registers for
902 _main (this should take care the --main-return command line option in
904 (genOr): removed some legacy pic-port instructions,
905 * src/pic16/genarith.c (genAddLit): re-enabled old code because
906 performing operations with SFR's causes data to be written more than
907 once to each SFR. Perhaps SFRs should be handled in special cases...
908 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
910 * src/pic16/main.c (_process_pragma): stack bound checking did not take

3193 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3194 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3195 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3196 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3197 always available in leading double underscore form. The C99 support is
3198 mostly missing, but it's a start.
3199 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3200 reserved identifier "__data".

3278 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3280 * device/lib/printf_large.c: removed inline assembly for portability and
3281 readability. Use printf_fast if speed or size are more important.
3282 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3283 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3285 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3287 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3288 prevent compiler warning
3290 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3292 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3293 moved to level 0 and declared as static. Also they are explicit
3294 placed in access bank. This was necessery because some times they
3295 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3296 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3297 optimizations. Currently only compare to unsigned char is implemented,
3298 * src/pic16/gen.c: added fReturnIdx array,
3299 * (struct resolvedIfx) is moved to gen.h and made public,
3300 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3301 * (aopForSym): added an optimization to directly store in stack of
3302 the operand of a SEND iCode,
3303 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3304 but as registers instead (AOP_REG) using the fReturnIdx array,
3305 * (pic16_freeAsmop): remove the freed register from the
3306 _G.sregsAlloc field,
3307 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3308 a compare of 'WREG',
3309 * (pic16_popGetTempRegCond): changed function prototype, now
3310 function takes also a bitVector argument v which holds the current
3311 set of registers that are allocated for stack access by aopForSym,
3312 registers allocated in aopForSym for accessing stack symbols are not
3313 any more part of the functions usedRegs field,
3314 * (genCall): some times aopOp is called for a stack variable to be
3315 send, aopForSym might perform the push, if this is true make sure
3316 that genCall doesn't push the variable twice by testing _G.resDirect,
3317 * (genFunction): changed testing for unspecified interrupt number
3318 from 256 to INTNO_UNSPEC,
3319 * modified selection scheme of frame pointer generation. Previously
3320 if function did use local registers a frame pointer was generated,
3321 now a frame pointer is generated only if function has arguments
3322 (that need PLUSW2 register access), or has stack arguments, or the
3323 compiler is not instructed to omit the frame pointer,
3324 * (genEndFunction): before restoring local registers that were saved
3325 in the function preamble, also restore the registers that *might*
3326 have been allocated for stack access,
3327 * (genRet): removed some old comments,
3328 * (genCmp, the active (RN's) version): added a call to the
3329 pic16_genCmp_special function to perform the compare with a more
3330 robust and optimized way,
3331 * (genInline): a feature has been added in inline code generation,
3332 which allows a wildcard variable substitution when writing inline
3333 assembly. Code is incomplete and experimental therefore undocumented,
3334 * (genCast): changed order of aopOp for result and right to allow
3335 aopForSym to directly load the result if possible,
3336 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3337 perform an optimized compare on some selected special occasions,
3338 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3339 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3340 generate an IVT any more,
3341 * src/pic16/main.c (pic16_optionsTable): added command line option
3343 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3344 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3346 * src/pic16/NOTES: Raphael Neider added in list of active developers
3347 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3348 jumptable_end to prevent bug #,
3349 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3350 inCond and outCond fields,
3351 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3352 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3353 turn off register spilling,
3354 * (packRegsForOneUse): synced with other ports' versions although it
3355 is not used currently,
3356 * (pic16_packRegisters): added an optimization while reading
3357 structure bitfields, some registers may be saved (malloc code is
3358 decreased by 80 bytes)
3360 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3362 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3363 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3364 this can be optimized more?
3366 2005-03-10 Raphael Neider <rneider AT web.de>
3368 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3369 genNearPointerGet): (hopefully) fixed access to bitfields via
3370 pointers (p->bitN = x; and x = p->bitN; failed)

3415 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3416 to keep the correct label reference count when adding/removing references
3417 to labels. A peephole file using this is appended to patch #1144962.

4004 Adding support for replacing ljmps with sjmps in jumptables
4005 generated for switch statements. For now you need to set the
4006 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4007 Now 4 algorithms for mcs51 jumptable generation are used:
4008 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4009 addresses loaded pc-relative for up to 112 cases and stack-pushing
4010 target addresses loaded with offset from dptr for up to 256 cases.

4040 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4042 * added libc directory. The current version of LibC contains string
4043 functions, ctype functions and macros and some functions of the
4044 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4045 be extensively tested in the future. Standard disclaimer here.
4046 Library is not automatically build yet. But one can build it by
4047 invoking 'make' inside the libc directory.
4048 * added ADC library under libio. Preliminary version yet.

4058 * (pic16_storeForReturn): optimized return of 0,
4059 * (genCmp): experimental code for new genCmp which uses PIC18's
4060 special compare&skip instructions. Initial tests fail some times
4061 with variables grater than 1 byte in size, so new code is disabled,
4062 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4064 * (genCast): began a fix to optimize the casting of a bit to another
4065 bit, now assigning a bitfield to another bitfield will fail, sorry,

4074 and 1 for banking instruction,
4075 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4076 caused stop processing pCodes after a inline assembly block,
4077 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4079 registers when it shouldn't,
4080 * src/pic16/ralloc.c (allocReg): add preliminary support for
4081 supporting a limited set of temporary registers,
4083 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4085 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

4088 (loadRegFromAop): recognize CLRH optimization,
4089 (genFunction): optimize RECEIVE iCodes in reentrant functions
4091 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6971 2004-01-27 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6973 * ChangeLog: changed "@" to " AT " in hopes of reducing spam and
6974 virus/worm forged address usage.
6976 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
6978 Fixed promotion, it should be done on AST level:
6979 * src/SDCCast.c (addCast): added promotion to int
6980 (decorateType): updated call to upCast()
6981 * src/SDCCicode.c (geniCodeLeftShift): removed call to
6982 usualUnaryConversions()
6984 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
6986 * support/regression/tests/literalop.c (mulWrapper): Added a
6987 wrapper to remove integer overflow warnings.

6991 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
6994 * support/regression/generate-cases.py (main): Changed from inline
6997 * doc/Makefile (install): Changed to depth first to get rid of
6998 missing directory install warning.
7000 * as/Makefile (install-doc): Made work on Mac.
7002 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
7004 * src/SDCCast.c: added an additional type flow in decorateType() of
7005 opposite direction, see feature request #860006; it's enabled at runtime
7006 by setting the environment variable SDCC_NEWTYPEFLOW
7007 * src/SDCCast.h: changed prototype of decorateType()
7008 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
7009 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
7010 'char' to 'int' can be omitted, if both operands are 'unsigned char';
7011 see feature request #877103
7012 * src/SDCCval.c: updated call of decorateType()
7013 (valBitwise): fixed bug #882876
7014 (valMinus): added promotion
7015 (valLogicAndOr): result is unsigned
7016 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
7017 * src/SDCCsymt.c (computeType),
7018 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
7019 must not cause an unsigned operation

7040 * src/pic/ralloc.h: applied patch from Slade Rich;
7041 added support for multiple code pages and multiple RAM banks on the
7042 PIC 14 port. The ASM files now no longer simply assume all the
7043 code / RAM are in the same page / bank. This means the linker can
7044 safely allocate code/RAM of separate ASM files to different pages/banks.
7045 * doc/sdccman.lyx: added Slade's tips
7046 * src/mcs51/peeph.def: fixed bug #880768

7058 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7059 strtof is not part of C89 and isn't included with Mac OS X.
7061 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7063 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7088 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7090 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7091 loaded with the linker search paths (-L arguments) and the libraries
7092 to be linked with the current source (-l arguments). Changes
7093 currently will affect only the pic16 port.
7094 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7095 include path the port specific paths and port specific libraries,
7096 * gplink command now contains the $3 argument,
7097 * src/pic16/device.h,
7098 * src/pic16/device.c,: structure PIC_device is made public and
7099 renamed to PIC16_device, the same for variable Pics which is renamed

7112 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
7114 Documenting changes from previous commits.
7115 * configure.in (version 1.56),
7116 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7117 when generating output files to configure the pic16 library,
7118 but now I've commented it out, since gputils aren't installed in the
7119 SF compile farm, so library won't compile
7121 * device/lib/Makefile.in (version 1.56): initially I've added in
7122 target 'all' the prerequestive 'model-pic16' so it compiled the
7123 pic16 library, but now I've commented it out for the same reasons
7125 * added targets 'model-pic16' and 'objects-pic16' to compile the
7127 * added target 'port-specific-objects-pic16' to handle the
7128 generated libraries and copy them into the build/ directory
7129 * added target 'clean-intermediate-pic16' to clean intermediate
7130 files into pic16 directory
7131 * in target 'installdirs' added line to create directory pic16 in
7132 the installation path
7134 * device/include/Makefile.in (version 1.11): in target 'install'
7135 added lines to copy all header files to installation path,
7136 * in target 'installdirs' added line create directory for pic16
7137 headers in the installation path

7152 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7153 option so that it actually works. Made it specific to the z80, since
7154 the gbz80 doesn't have these kinds of I/O ports.
7156 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7158 * device/include/z180.h,

7180 Mainly changes to support compilation of the device libraries
7181 * src/pic16/device.c: stack is allocated via symbol and not
7182 via literal number. The symbol is placed in the corresponding
7183 position of the data ram
7184 * (pic16_dump_section): relocatable and absolute uninitialized
7185 data are now emitted in sorted order to reduce section naming,
7186 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7187 weren't marked as being in the access bank,
7189 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7191 Added portion of GNU PIC Library under the directory
7192 device/include/pic16 and device/lib/pic16. These files
7193 contain the declarations of SFRs for the PIC18Fxx2 devices.
7194 The directory is initialized via configure from toplevel.
7196 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7198 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

7210 2004-01-12 Bernhard Held <bernhard AT bernhardheld.de>
7212 * src/SDCCast.c (decorateType): replacing 'ul > 0' by '!ul' results
7213 in simpler and even better code
7215 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
7217 * src/SDCCicode.c (operandOperation): fixed bug #874819

7223 * doc/sdccman.lyx: Moved and added some sections, small changes
7224 all over. Telling LaTeX to be less strict with word spacing
7225 to better keep the right margin. Changed some notes about
7226 maintainance of the ports in section 3.2.1 - is it OK like this?
7228 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7266 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7268 * src/pic16/peeph.def: all peepholes with movff are commented out,
7269 because there is a problem in the pcode peep optimizer,
7270 * src/pic16/ralloc.c: the register allocator can now reuse local

7335 directive when no overlay data exist
7336 * (picglue): modified to emit uninitialized data segment
7337 according to udata_section_name

7409 Bug reported from Jesus Calvino-Fraga
7411 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7413 * sdcc.spec: updated
7414 * device/include/Makefile.in: don't install CVS directories
7415 * device/lib/Makefile.in: added removal of CVS directories after install
7416 * doc/Makefile: fixed install, added local_icons
7417 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7418 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7419 * src/ds390/gen.c (genRightShift): fixed bug #870788

7422 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7424 PIC16 port related changes:
7425 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7426 added variable stackPos,
7428 * gen.c: genCall, assignResultValue: added support for
7429 pushing/retrieving function parameters to/from stack,
7430 genFunction,genEndFunction: setup stack frame for the
7432 genAddrOf: will be changed according to bug 863624
7434 * added files genutils.c and genutils.h which contain gen*
7435 debugged and optimised functions extracted from gen.c
7437 * glue.c: added variable 'externs' which holds extern symbols,
7438 pic16emitRegularMap: is modified to properly handle relocatable
7439 symbols under the new scheme,
7440 pic16createInterruptVect: is modified
7441 pic16printPublics: is modified to emit 'global' assembler directives,
7442 added pic16_printExterns to print extern symbols,
7443 pic16glue: initializes stack/frame pointer in the beginning of
7444 the assembly output. Temporary hack, will be corrected later,
7445 because gplink yet does not support stack and SDCC does not
7446 yet support a type of crt0.o object to create the final binary.
7448 * Removed many lines that contain 8051 legacy code.
7449 * The code is finally placed under a 'code' directive.
7450 * Added port specific options.
7452 * _process_pragma: simplified since now we do not need *special*
7453 include file to define SFR registers. But a separate header
7454 will be needed. This will be developed later.
7455 * _pic16_parseOptions: added, parses port specific options:
7456 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7457 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7458 --preplace-udata-with=
7460 * _pic16_setDefaultOptions: modified to initialize section names,
7461 but hack is temporarly out of order since it needs improvement.
7462 * _pic16_genAssemblerPreamble: configuration words are emitted by
7463 their address instead of their name. This part is incomplete and
7464 supports only the 18Fxx2 devices. Other devices will emit an error
7465 during assembly since they do not contain the same set of config
7467 * _pic16_genIVT: is modified,
7469 * pcode.c: added definitions for some hardware registers that are needed
7471 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7472 All PCI entries are updated. Now LFSR is supported.
7473 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7474 * added pic16_newpCodeOpLit2 to support instructions with
7475 two literal arguments
7476 * pic16_pCode2str: corrected code that emits assembler instructions
7477 with two literal operands and those that have an access bit modifier
7478 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7479 this fixes a bug which caused some labels to be lost, when an
7480 assembler directive was added, i.e. banksel,
7481 * pic16_FixRegisterBanking: improved logic that causes the insertion
7483 * InlineFunction: functions that are called once, are not any more
7484 inlined. This can be a port option in the future,
7486 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7488 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7489 hold the corresponding uninitialized symbols,
7490 * pic16_allocProcessorRegister: registers have explicit marked the
7492 * pic16_allocInternalRegister: registers are explicit marked as
7494 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7495 processing list, so bit registers were lost,
7498 * ralloc.h: added field 'accessBank' and original symbol operand
7499 in register definition,
7500 * removed the field isMapped from register definition,
7502 ** Several functions have been removed from various sources:
7503 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7504 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7505 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7506 pic16_assignRelocatableRegisters
7508 ** others have been introduced:
7509 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7510 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7512 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7514 * support/scripts/inc2h.pl: changed definition of BIT_AT
7515 to emit 'sbit at' instead of 'bit at'. This was a request.
7517 PIC16 port related preliminary changes:
7518 * gen.c: prefixed function popRegFromString with
7519 pic16_ and all references to it corrected
7520 * pcode.c: all pic16_pc_* hardware registers prefixed
7521 with underscore (_),
7522 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7523 * ralloc.c: newReg(): when register is REG_SFR then
7524 set address to rIdx,
7525 pic16_allocProcessorRegister(): marks register wasUsed=0
7526 pic16_writeUsedRegs(): added a call to assign processor
7527 registers via pic16_assignFixedRegisters
7529 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7531 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7532 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7533 variables in unused register banks. Also the SSEG is placed
7534 wherever there is enough space for it, and IDATA can be anywhere
7535 in internal RAM. For now compile using -Wl-Y[stack_size].
7536 The mem file is different for this option as well, since it
7537 makes no sense of talking about DSEG lenght.
7539 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7541 * src/SDCClrange.c: fixed bug 869095 that caused segfault

7786 * src/SDCCast.c (decorateType): disabled a transformation I added in
7787 revision 1.188 (access to fields of a structure at an absolute address);
7788 it breaks with bitfields, extern declarations, and gcse analysis.
7789 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7790 could be assigned through a pointer, so don't complain.

7898 xdata initialization slightly shorter
7900 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8454 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8455 refer to the const or volatile state of the pointer itself.

8549 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8550 copied from genNearPointerSet()
8551 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8552 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8568 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8569 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8570 type for bits was changed. It resulted in bit variables becoming
8571 global, which is not permitted in PIC 14 assembly output.

8588 A few small changes that speed up the peephole optimizer.
8592 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8594 Try to make the peephole optimizer smarter by maintaining
8595 an association between the assembly source code and the
8596 iCodes that originated them. Put this information to use
8597 with a new peephole rule condition "notVolatile" so that
8598 the rules can be aggressive yet still safe.
8603 * src/mcs51/peeph.def
8605 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8609 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8610 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8611 if the left or right operand symbols have the accuse flag set.
8613 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8615 Changed the type of the result of the ! (NOT) operator to char;
8616 previously it returned the same type as the source. This allows
8617 us to eliminate all the genFloatNot functions (all of its target
8618 implementations were very buggy) since !float can use the same

8630 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8631 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8632 during interrupts. Ensure WSAVE is located at a shared bank address.
8633 2. Fixed page selection in some places
8634 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8635 the registers name strings.
8636 4. Fixed "signed / unsigned compare" compiler warnings.
8637 5. The PIC port manages its own allocation of the general purpose
8638 registers, but makes no attempt to reuse them. As a result when
8639 compiling it soon runs out of general purpose registers. Some
8640 additional code was added to the files pcode.c and device.c to walk
8641 through the function call tree and rename the registers so that they
8651 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8652 genPlus() & genMinus() when the result is the same as left or right

8658 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8660 Made bitfield a distinct type from bit so that bitfields
8661 convert as per ANSI C and bits retain their traditional
8662 boolean style behaviour. Implemented bitfield support in
8670 * src/ds390/gen.c: bit v bitfield split
8671 * src/z80/gen.c: New support for bitfields
8672 * support/regression/tests/bitfields.c: reenabled z80,
8675 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8677 Rules 246.x, 247.x relate to bitfields, the others speed up
8678 access to xdata mapped I/O devices.
8680 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8682 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8684 Cleaned up genPackBits and genUnpackBits and added two helper
8685 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8686 for literal assignments in genPackBits (thanks to Frieder for
8692 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8694 Fixed bug #748310 (pointer to function type mishandled when the
8695 function name is omitted). Also fixed a SIGSEGV when a function
8696 attribute (reentrant, etc) is used on a non-function or on a
8697 function but misplaced before the parameter list.
8699 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8701 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8702 * support/Util/SDCCerr.h,

8724 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8726 Made the constant following the "interrupt" keyword optional. If
8727 omitted, the function will not automatically be given an entry
8728 in the interrupt vector table (similar to #pragma NOIV, but
8729 less syntacticly kludgy). The interrupt number is also now
8730 range checked. Also fixed a bug in the high order bit example

8744 * src/SDCCicode.c (operandOperation): rewritten some ops
8745 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8746 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8748 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8749 be re-activated by defining REDUCE_LITERALS)
8750 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8751 unsigned, but are signed by default
8752 * src/SDCCval.c (constVal): rearranged
8753 * src/SDCCval.c (valMod): preliminary fix
8754 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8796 constants are unsigned; added recognition of "u" flag for unsigned
8797 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8798 * src/SDCCval.c (valDiv, valMod): fixed signdness
8799 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8800 signedness of modulo, left and right shift

9252 * src/SDCCmain.c: fixed compiling + linking with object files
9254 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9257 added --disable-pic16-port
9258 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9259 * src/SDCCmain.c: linkOptions is changed to set *,
9260 added if/endif conditional macros to remove options help
9261 messages from optionsTable when a port is not configured, added
9262 support for the PIc16 port in the ports table, when executing
9263 the compiler with no port specified on command line, a default
9264 port is selected with the new macro DEFAULT_PORT which is
9265 defined in port.h, in setDefaultOptions() linkOptions is removed
9266 from initialization assignment, since now it is a set,
9267 parseCmdLine uses setParseWithComma for linkOptions, in
9268 linkEdit() linkOptions are accessed with new function indexSet()
9269 which returns the i'th item of a set variable. See SDCCset.c, in
9270 linkEdit() when calling buildCmdLine(), added linkOptions as
9271 last argument. Now users can pass arguments to gplink via the
9272 -Wl option, main() uses pic16glue() to glue up pic16 programs

9284 * src/pic16/glue.c: commented out some error producing lines
9285 * src/pic16/main.c: __config directives are commented out to stop
9286 gpasm complaining and test the linkage with gplink, _linkCmd and
9287 _asmCmd changed to be more gplink and gpasm friendly
9288 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9289 produced an error when parsed, peep rule 12 is added to utilize
9290 movff, but it is commented out since the pCode does not support
9291 yet a command with 2 address arguments
9293 2003-05-18 <johan AT balder>
9295 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9296 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9320 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9322 2003-05-11 Borut Razem <borut.razem AT siol.net>
9324 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9325 the path of bin directory, so that PATH is the only env. variable, which has to be set
9326 in case of standard installation.
9327 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10370 value from option --iram-size.
10372 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10374 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10377 2002-09-18 <wiml AT hhhh.org>
10379 * SDCClrange.h: exposed setFromRange() and setToRange()
10380 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10381 packRegsForAccUse() (bug 542397)
10382 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10383 multiple times and emitting the fetch operations more than once
10384 added aopGetUsesAcc() function to allow binary operators to
10385 fetch their operands in the correct order; made genMinus() emit
10386 compact code for X = LITERAL - Y
10388 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10389 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10390 sprintf() in line 1267.
10392 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10393 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10396 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10397 Changes to aslink (All the changes are marked with 'JCF'):
10399 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10402 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10403 area BSEG. Also moves, if possible, the DATA area down into the internal
10404 ram so more space is available.
10406 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10409 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10410 not bytes. Function summary() which creates a memory usage summary
10411 file with extension .mem. Reports of overlaping stack and small stack
10412 size. If the space for the stack is less than 16 bytes aslink trows a
10415 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10416 the 8051. Option 'y' for memory summary output file.
10418 Changes to sdcc (All the changes are marked with 'JCF'):
10420 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10422 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10423 overlaying area for it (uses RegBankUsed[4]).
10425 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10426 bank zero as used by default. By default aslink locates the stack
10427 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10428 the creation of the .mem file. Delegates the allocation of data area
10429 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10430 the begining of the stack area to aslink.
10432 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10433 glue() in SDCCglue.c creates an area for it.
10435 2002-09-03 Borut Razem <borut.razem AT siol.net>
10436 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10437 sdcc/src/pic/glue.c:
10438 introduced atexit() handler for teporay files removal in case of
10439 errors, assertions, ...
10441 2002-08-29 Borut Razem <borut.razem AT siol.net>
10442 * sdcc/support/cpp2/auto-host_vc_in.h:
10443 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10444 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10445 Maybe there is a similar problem with BORLANDC? It should be checked!
10447 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10448 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10449 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10450 was not executed, and the compiler (cl) launched a warning:
10451 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10453 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10454 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10456 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10457 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10459 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10460 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10461 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10462 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10463 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10464 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10465 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10466 - added Release configuration in VS projects
10467 - review of compiler an linker options
10468 - VC .exe files are generated in bin_vc directory, not to interfere
10469 with binaries generated from other projects (cygwin, mingw, bcc ...)
10471 * sdcc/src/yacc.dsp: added
10473 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10474 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10475 and insert the version number definitions from .version
10477 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10479 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10480 added - genarate auto-host.h using auto-host_vc_in.h as template
10483 removed from CVS, generated automatically
10485 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10486 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10488 2002-08-11 Borut Razem <borut.razem AT siol.net>
10489 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10491 2002-08-10 Borut Razem <borut.razem AT siol.net>
10492 * src/SDCCmain.c (main):
10493 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10494 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10495 The consequence was that some temporary files were not removed.
10498 unification of code in functions tempfilename() and tempfile():
10499 function tempnam() is defined in Visual Studio 6.0 and .NET
10501 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10503 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10504 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10505 - removed compiler command line option /WX: Treats all warnings as errors
10506 - update a list of source files, included into the project
10508 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10509 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10510 changed project type to Generic Project so that can be correcly converted to VS.NET project
10512 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10514 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10516 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10518 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10519 added return 0 statements after assert() to make compiler happy
10521 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10522 added newline in the def file to keep MSC compiler satisfied
10524 * sdcc/src/z80/gen.c:
10525 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10526 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10527 - solved MSC error in function aopDump()
10529 * sdcc_vc.h: define PREFIX as "\\sdcc"
10531 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10532 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10569 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10571 2002-03-28 Johan Knol <johan AT balder>
10573 * src/SDCCval.c: fixed bug #532436
10575 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10577 Added "char *Processor" field to the port structure.
10580 Added -p option. Allows port dependent processor to be specified.
10583 Initialized the new field char *Processor field to NULL in all ports
10586 Compiler generated registers for interrupt context saving
10587 were not getting allocated.
10589 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10592 Fixed left shift. Will promote the left side of a left shift
10593 if a) left shifting more than size of operand or b) when assigned
10594 to something size > size of left side

10704 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10706 * sdcc/src/SDCCloop.c:
10707 Previous fix was not good. basic blocks that have "break" or "return" are
10708 not really partof a loop , but live ranges used in these blocks should
10709 be live thru the entire loop, so set partOfLoop but don't add them to
10712 2002-02-21 <johan AT FRIJA>
10714 * src/SDCCcse.c: fixed bug #514308
10716 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
