475 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
477 Enabled VPATH feature: changed nearly all Makefiles (149 files).
478 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
480 One basic decision: e.g. src/clean.mk includes further files. In order
481 to make this work there are two solutions:
482 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
483 run configure on them. This way they can use
484 'include $(srcdir)/port-clean.mk'
485 - always include clean.mk by the Makefile at the same level. To avoid
486 that `make clean` tries to include and build Makefile.dep the
487 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
488 implemented, because now even `make uninstall` doesn't create
489 Makefile.in. clean.mk could be eliminated by pasting it in
492 * debugger/mcs51/Makefile.in: build own objects from library sources
493 (SLIB, SDCC) in current directory
495 * configure, configure.in: renamed --disable-device-lib-build in
496 --disable-device-lib; added --enable-doc, the required tools are
497 searched by configure; added result message; the toolchain for the
498 belonging ports are now only built, if the port is enabled.
500 * support/regression/*: all output is written in directory gen, because
501 the fwk and ports directories don't livet in the build tree using vpath
503 * doc/sdccman.lyx: renamed --disable-device-lib-build to
504 --disable-device-lib, added --enable-doc, added section VPATH
506 * sim/ucsim/configure.in,
507 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
508 z80 are enabled by default
510 2006-04-24 Raphael Neider <rneider AT web.de>
512 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
513 to config word, "pic14_"-prefixed some extern functions

762 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
764 * doc/sdccman.lyx: reverted to version 1.129 of december as my latest

780 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
781 implemented patch 1120823 Thanks to Willy De la Court (normal
782 interrupts need an interrupt number now if they are made critical),
783 and enabled nesting of critical functions though not for gbz80
784 (genCritical, genEndCritical): added functions
785 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
786 * src/z80/mappings.i: added "ei" to all mappings

792 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
793 archive with gcc 4.1 on mips and wrote the patch"
795 2006-03-16 Raphael Neider <rneider AT web.de>
797 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
798 the left operand is shorter than the result (c* = lit-c* + int),
800 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
803 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
805 * src/.version: increased version number to 2.5.5
806 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
807 linking is done manually in pic16 port's _linkEdit,
808 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
809 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
810 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
811 allocate asmop as AOP_ACC,
812 (aopForRemat): added parameter 'bool result' in function declaration,

825 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
826 call to allocReg, not by manually allocating a new one,
827 (pic16_assignRegisters): now before going through the register
828 allocating functions mark all registers as free. This eliminates some
829 side effects resulting from peephole parser done earlier in the backbone
831 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
833 * src/SDCCicode.c (geniCodeLogic),

878 * src/ds390/peeph.def: disabled 186.d and 227.a as fix for #1434401
879 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
881 2006-03-06 Borut Razem <borut.razem AT siol.net>
883 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
884 made the linker quiet
886 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
888 * src/pic16/gen.c (genPcall): fixed bug #1443644
889 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
890 which dumps before the function entry point a data byte which represents
891 the number of the local variables used by the specified function, added
892 'xinst' for initial support for Extended Instruction Support,
893 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
894 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
895 port->fun_prefix anymore (may change later),
896 (genFunction, genEndFunction): do not store/restore local registers for
897 _main (this should take care the --main-return command line option in
899 (genOr): removed some legacy pic-port instructions,
900 * src/pic16/genarith.c (genAddLit): re-enabled old code because
901 performing operations with SFR's causes data to be written more than
902 once to each SFR. Perhaps SFRs should be handled in special cases...
903 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
905 * src/pic16/main.c (_process_pragma): stack bound checking did not take
906 into account for stack starting position,
907 (struct OPTIONS pic16_optionsTable): added command line argument
908 --extended or -y for Extended Instruction Support,
909 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
910 (deassignLRs): *** perhaps the most important change, old 'for' code
911 (commented out for reference), didn't account for some registers which
912 were left marked 'not free' after a pointer operation. The change

3188 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3189 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3190 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3191 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3192 always available in leading double underscore form. The C99 support is
3193 mostly missing, but it's a start.
3194 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3195 reserved identifier "__data".
3197 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3273 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3275 * device/lib/printf_large.c: removed inline assembly for portability and
3276 readability. Use printf_fast if speed or size are more important.
3277 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3278 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3280 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3282 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3283 prevent compiler warning
3285 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3287 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3288 moved to level 0 and declared as static. Also they are explicit
3289 placed in access bank. This was necessery because some times they
3290 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3291 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3292 optimizations. Currently only compare to unsigned char is implemented,
3293 * src/pic16/gen.c: added fReturnIdx array,
3294 * (struct resolvedIfx) is moved to gen.h and made public,
3295 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3296 * (aopForSym): added an optimization to directly store in stack of
3297 the operand of a SEND iCode,
3298 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3299 but as registers instead (AOP_REG) using the fReturnIdx array,
3300 * (pic16_freeAsmop): remove the freed register from the
3301 _G.sregsAlloc field,
3302 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3303 a compare of 'WREG',
3304 * (pic16_popGetTempRegCond): changed function prototype, now
3305 function takes also a bitVector argument v which holds the current
3306 set of registers that are allocated for stack access by aopForSym,
3307 registers allocated in aopForSym for accessing stack symbols are not
3308 any more part of the functions usedRegs field,
3309 * (genCall): some times aopOp is called for a stack variable to be
3310 send, aopForSym might perform the push, if this is true make sure
3311 that genCall doesn't push the variable twice by testing _G.resDirect,
3312 * (genFunction): changed testing for unspecified interrupt number
3313 from 256 to INTNO_UNSPEC,
3314 * modified selection scheme of frame pointer generation. Previously
3315 if function did use local registers a frame pointer was generated,
3316 now a frame pointer is generated only if function has arguments
3317 (that need PLUSW2 register access), or has stack arguments, or the
3318 compiler is not instructed to omit the frame pointer,
3319 * (genEndFunction): before restoring local registers that were saved
3320 in the function preamble, also restore the registers that *might*
3321 have been allocated for stack access,
3322 * (genRet): removed some old comments,
3323 * (genCmp, the active (RN's) version): added a call to the
3324 pic16_genCmp_special function to perform the compare with a more
3325 robust and optimized way,
3326 * (genInline): a feature has been added in inline code generation,
3327 which allows a wildcard variable substitution when writing inline
3328 assembly. Code is incomplete and experimental therefore undocumented,
3329 * (genCast): changed order of aopOp for result and right to allow
3330 aopForSym to directly load the result if possible,
3331 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3332 perform an optimized compare on some selected special occasions,
3333 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3334 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3335 generate an IVT any more,
3336 * src/pic16/main.c (pic16_optionsTable): added command line option
3338 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3339 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3341 * src/pic16/NOTES: Raphael Neider added in list of active developers
3342 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3343 jumptable_end to prevent bug #,
3344 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3345 inCond and outCond fields,
3346 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3347 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3348 turn off register spilling,
3349 * (packRegsForOneUse): synced with other ports' versions although it
3350 is not used currently,
3351 * (pic16_packRegisters): added an optimization while reading
3352 structure bitfields, some registers may be saved (malloc code is
3353 decreased by 80 bytes)
3355 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3357 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3358 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3359 this can be optimized more?
3361 2005-03-10 Raphael Neider <rneider AT web.de>
3363 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3364 genNearPointerGet): (hopefully) fixed access to bitfields via
3365 pointers (p->bitN = x; and x = p->bitN; failed)

3411 to keep the correct label reference count when adding/removing references
3412 to labels. A peephole file using this is appended to patch #1144962.

3999 Adding support for replacing ljmps with sjmps in jumptables
4000 generated for switch statements. For now you need to set the
4001 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4002 Now 4 algorithms for mcs51 jumptable generation are used:
4003 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4004 addresses loaded pc-relative for up to 112 cases and stack-pushing
4005 target addresses loaded with offset from dptr for up to 256 cases.

4035 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4037 * added libc directory. The current version of LibC contains string
4038 functions, ctype functions and macros and some functions of the
4039 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4040 be extensively tested in the future. Standard disclaimer here.
4041 Library is not automatically build yet. But one can build it by
4042 invoking 'make' inside the libc directory.
4043 * added ADC library under libio. Preliminary version yet.

4053 * (pic16_storeForReturn): optimized return of 0,
4054 * (genCmp): experimental code for new genCmp which uses PIC18's
4055 special compare&skip instructions. Initial tests fail some times
4056 with variables grater than 1 byte in size, so new code is disabled,
4057 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4059 * (genCast): began a fix to optimize the casting of a bit to another
4060 bit, now assigning a bitfield to another bitfield will fail, sorry,

4069 and 1 for banking instruction,
4070 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4071 caused stop processing pCodes after a inline assembly block,
4072 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4074 registers when it shouldn't,
4075 * src/pic16/ralloc.c (allocReg): add preliminary support for
4076 supporting a limited set of temporary registers,
4078 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6974 * src/SDCCast.c (addCast): added promotion to int
6975 (decorateType): updated call to upCast()
6976 * src/SDCCicode.c (geniCodeLeftShift): removed call to
6977 usualUnaryConversions()
6979 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
6981 * support/regression/tests/literalop.c (mulWrapper): Added a
6982 wrapper to remove integer overflow warnings.
6984 * support/regression/tests/float_trans.c: Made work on host.
6986 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
6989 * support/regression/generate-cases.py (main): Changed from inline
6992 * doc/Makefile (install): Changed to depth first to get rid of
6993 missing directory install warning.
6995 * as/Makefile (install-doc): Made work on Mac.
6997 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
6999 * src/SDCCast.c: added an additional type flow in decorateType() of
7000 opposite direction, see feature request #860006; it's enabled at runtime
7001 by setting the environment variable SDCC_NEWTYPEFLOW
7002 * src/SDCCast.h: changed prototype of decorateType()
7003 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
7004 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
7005 'char' to 'int' can be omitted, if both operands are 'unsigned char';
7006 see feature request #877103
7007 * src/SDCCval.c: updated call of decorateType()
7008 (valBitwise): fixed bug #882876
7009 (valMinus): added promotion
7010 (valLogicAndOr): result is unsigned
7011 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
7012 * src/SDCCsymt.c (computeType),
7013 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
7014 must not cause an unsigned operation
7015 * src/pic/glue (pic14emitRegularMap),

7035 * src/pic/ralloc.h: applied patch from Slade Rich;
7036 added support for multiple code pages and multiple RAM banks on the
7037 PIC 14 port. The ASM files now no longer simply assume all the
7038 code / RAM are in the same page / bank. This means the linker can
7039 safely allocate code/RAM of separate ASM files to different pages/banks.
7040 * doc/sdccman.lyx: added Slade's tips
7041 * src/mcs51/peeph.def: fixed bug #880768

7053 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7054 strtof is not part of C89 and isn't included with Mac OS X.
7056 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7058 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7083 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7085 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7086 loaded with the linker search paths (-L arguments) and the libraries
7087 to be linked with the current source (-l arguments). Changes
7088 currently will affect only the pic16 port.
7089 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7090 include path the port specific paths and port specific libraries,
7091 * gplink command now contains the $3 argument,
7092 * src/pic16/device.h,
7093 * src/pic16/device.c,: structure PIC_device is made public and
7094 renamed to PIC16_device, the same for variable Pics which is renamed

7109 Documenting changes from previous commits.
7110 * configure.in (version 1.56),
7111 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7112 when generating output files to configure the pic16 library,
7113 but now I've commented it out, since gputils aren't installed in the
7114 SF compile farm, so library won't compile
7116 * device/lib/Makefile.in (version 1.56): initially I've added in
7117 target 'all' the prerequestive 'model-pic16' so it compiled the
7118 pic16 library, but now I've commented it out for the same reasons
7120 * added targets 'model-pic16' and 'objects-pic16' to compile the
7122 * added target 'port-specific-objects-pic16' to handle the
7123 generated libraries and copy them into the build/ directory
7124 * added target 'clean-intermediate-pic16' to clean intermediate
7125 files into pic16 directory
7126 * in target 'installdirs' added line to create directory pic16 in
7127 the installation path
7129 * device/include/Makefile.in (version 1.11): in target 'install'
7130 added lines to copy all header files to installation path,
7131 * in target 'installdirs' added line create directory for pic16
7132 headers in the installation path

7147 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7148 option so that it actually works. Made it specific to the z80, since
7149 the gbz80 doesn't have these kinds of I/O ports.
7151 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7153 * device/include/z180.h,

7177 via literal number. The symbol is placed in the corresponding
7178 position of the data ram
7179 * (pic16_dump_section): relocatable and absolute uninitialized
7180 data are now emitted in sorted order to reduce section naming,
7181 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7182 weren't marked as being in the access bank,
7184 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7186 Added portion of GNU PIC Library under the directory
7187 device/include/pic16 and device/lib/pic16. These files
7188 contain the declarations of SFRs for the PIC18Fxx2 devices.
7189 The directory is initialized via configure from toplevel.

7219 all over. Telling LaTeX to be less strict with word spacing
7220 to better keep the right margin. Changed some notes about
7221 maintainance of the ports in section 3.2.1 - is it OK like this?
7223 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7263 * src/pic16/peeph.def: all peepholes with movff are commented out,
7264 because there is a problem in the pcode peep optimizer,
7265 * src/pic16/ralloc.c: the register allocator can now reuse local

7404 Bug reported from Jesus Calvino-Fraga
7406 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7408 * sdcc.spec: updated
7409 * device/include/Makefile.in: don't install CVS directories

7417 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7419 PIC16 port related changes:
7420 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7421 added variable stackPos,
7423 * gen.c: genCall, assignResultValue: added support for
7424 pushing/retrieving function parameters to/from stack,
7425 genFunction,genEndFunction: setup stack frame for the
7427 genAddrOf: will be changed according to bug 863624
7429 * added files genutils.c and genutils.h which contain gen*
7430 debugged and optimised functions extracted from gen.c
7432 * glue.c: added variable 'externs' which holds extern symbols,
7433 pic16emitRegularMap: is modified to properly handle relocatable
7434 symbols under the new scheme,
7435 pic16createInterruptVect: is modified
7436 pic16printPublics: is modified to emit 'global' assembler directives,
7437 added pic16_printExterns to print extern symbols,
7438 pic16glue: initializes stack/frame pointer in the beginning of
7439 the assembly output. Temporary hack, will be corrected later,
7440 because gplink yet does not support stack and SDCC does not
7441 yet support a type of crt0.o object to create the final binary.
7443 * Removed many lines that contain 8051 legacy code.
7444 * The code is finally placed under a 'code' directive.
7445 * Added port specific options.
7447 * _process_pragma: simplified since now we do not need *special*
7448 include file to define SFR registers. But a separate header
7449 will be needed. This will be developed later.
7450 * _pic16_parseOptions: added, parses port specific options:
7451 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7452 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7453 --preplace-udata-with=
7455 * _pic16_setDefaultOptions: modified to initialize section names,
7456 but hack is temporarly out of order since it needs improvement.
7457 * _pic16_genAssemblerPreamble: configuration words are emitted by
7458 their address instead of their name. This part is incomplete and
7459 supports only the 18Fxx2 devices. Other devices will emit an error
7460 during assembly since they do not contain the same set of config
7462 * _pic16_genIVT: is modified,
7464 * pcode.c: added definitions for some hardware registers that are needed
7466 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7467 All PCI entries are updated. Now LFSR is supported.
7468 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7469 * added pic16_newpCodeOpLit2 to support instructions with
7470 two literal arguments
7471 * pic16_pCode2str: corrected code that emits assembler instructions
7472 with two literal operands and those that have an access bit modifier
7473 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7474 this fixes a bug which caused some labels to be lost, when an
7475 assembler directive was added, i.e. banksel,
7476 * pic16_FixRegisterBanking: improved logic that causes the insertion
7478 * InlineFunction: functions that are called once, are not any more
7479 inlined. This can be a port option in the future,
7481 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7483 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7484 hold the corresponding uninitialized symbols,
7485 * pic16_allocProcessorRegister: registers have explicit marked the
7487 * pic16_allocInternalRegister: registers are explicit marked as
7489 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7490 processing list, so bit registers were lost,
7493 * ralloc.h: added field 'accessBank' and original symbol operand
7494 in register definition,
7495 * removed the field isMapped from register definition,
7497 ** Several functions have been removed from various sources:
7498 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7499 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7500 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7501 pic16_assignRelocatableRegisters
7503 ** others have been introduced:
7504 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7505 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7507 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7509 * support/scripts/inc2h.pl: changed definition of BIT_AT
7510 to emit 'sbit at' instead of 'bit at'. This was a request.
7512 PIC16 port related preliminary changes:
7513 * gen.c: prefixed function popRegFromString with
7514 pic16_ and all references to it corrected
7515 * pcode.c: all pic16_pc_* hardware registers prefixed
7516 with underscore (_),
7517 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7518 * ralloc.c: newReg(): when register is REG_SFR then
7519 set address to rIdx,
7520 pic16_allocProcessorRegister(): marks register wasUsed=0
7521 pic16_writeUsedRegs(): added a call to assign processor
7522 registers via pic16_assignFixedRegisters
7524 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7526 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7527 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7528 variables in unused register banks. Also the SSEG is placed
7529 wherever there is enough space for it, and IDATA can be anywhere
7530 in internal RAM. For now compile using -Wl-Y[stack_size].
7531 The mem file is different for this option as well, since it
7532 makes no sense of talking about DSEG lenght.
7534 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7536 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7537 in certain cases, e.g. when ROM assignment, patch provided
7538 from Albert den Haan.

7781 * src/SDCCast.c (decorateType): disabled a transformation I added in
7782 revision 1.188 (access to fields of a structure at an absolute address);
7783 it breaks with bitfields, extern declarations, and gcse analysis.
7784 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7785 could be assigned through a pointer, so don't complain.

7893 xdata initialization slightly shorter
7895 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8545 copied from genNearPointerSet()
8546 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8547 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8563 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8564 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8565 type for bits was changed. It resulted in bit variables becoming
8566 global, which is not permitted in PIC 14 assembly output.
8568 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8570 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8581 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8583 A few small changes that speed up the peephole optimizer.
8587 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8589 Try to make the peephole optimizer smarter by maintaining
8590 an association between the assembly source code and the
8591 iCodes that originated them. Put this information to use
8592 with a new peephole rule condition "notVolatile" so that
8593 the rules can be aggressive yet still safe.
8598 * src/mcs51/peeph.def
8600 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8604 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8605 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8606 if the left or right operand symbols have the accuse flag set.
8608 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8610 Changed the type of the result of the ! (NOT) operator to char;
8611 previously it returned the same type as the source. This allows
8612 us to eliminate all the genFloatNot functions (all of its target
8613 implementations were very buggy) since !float can use the same
8616 * src/SDCCicode.c (ast2iCode): ! returns char
8617 * src/mcs51/gen.c (genNot, genNotFloat),
8618 * src/ds390/gen.c (genNot, genNotFloat),
8619 * src/z80/gen.c (genNot, genNotFloat),
8620 * src/pic/gen.c (genNot, genNotFloat),
8621 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
8623 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
8625 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8626 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8627 during interrupts. Ensure WSAVE is located at a shared bank address.
8628 2. Fixed page selection in some places
8629 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8630 the registers name strings.
8631 4. Fixed "signed / unsigned compare" compiler warnings.
8632 5. The PIC port manages its own allocation of the general purpose
8633 registers, but makes no attempt to reuse them. As a result when
8634 compiling it soon runs out of general purpose registers. Some
8635 additional code was added to the files pcode.c and device.c to walk
8636 through the function call tree and rename the registers so that they
8646 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8647 genPlus() & genMinus() when the result is the same as left or right
8649 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8653 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8655 Made bitfield a distinct type from bit so that bitfields
8656 convert as per ANSI C and bits retain their traditional
8657 boolean style behaviour. Implemented bitfield support in
8665 * src/ds390/gen.c: bit v bitfield split
8666 * src/z80/gen.c: New support for bitfields
8667 * support/regression/tests/bitfields.c: reenabled z80,
8670 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8672 Rules 246.x, 247.x relate to bitfields, the others speed up
8673 access to xdata mapped I/O devices.
8675 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8677 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8679 Cleaned up genPackBits and genUnpackBits and added two helper
8680 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8681 for literal assignments in genPackBits (thanks to Frieder for
8687 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8689 Fixed bug #748310 (pointer to function type mishandled when the
8690 function name is omitted). Also fixed a SIGSEGV when a function
8691 attribute (reentrant, etc) is used on a non-function or on a
8692 function but misplaced before the parameter list.
8694 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8696 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8697 * support/Util/SDCCerr.h,
8698 * support/Util/SDCCerr.c: Added func attr misuse error msg

8719 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8721 Made the constant following the "interrupt" keyword optional. If
8722 omitted, the function will not automatically be given an entry
8723 in the interrupt vector table (similar to #pragma NOIV, but
8724 less syntacticly kludgy). The interrupt number is also now
8725 range checked. Also fixed a bug in the high order bit example
8732 * support/Util/SDCCerr.c
8733 * support/Util/SDCCerr.h
8736 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

8739 * src/SDCCicode.c (operandOperation): rewritten some ops
8740 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8741 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8743 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8744 be re-activated by defining REDUCE_LITERALS)
8745 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8746 unsigned, but are signed by default
8747 * src/SDCCval.c (constVal): rearranged
8748 * src/SDCCval.c (valMod): preliminary fix
8749 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8791 constants are unsigned; added recognition of "u" flag for unsigned
8792 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8793 * src/SDCCval.c (valDiv, valMod): fixed signdness
8794 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8795 signedness of modulo, left and right shift

9201 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9202 the regression tests I'm not brave enough to enable 245.b, 245.c
9203 * doc/sdccman.lyx: added latex preamble for hyperref package.
9204 Using pdflatex this will give you a hyperlinked pdf file with
9205 bookmarks. (prepend '%' before /usepackage if this breaks something)

9254 * src/SDCCmain.c: linkOptions is changed to set *,
9255 added if/endif conditional macros to remove options help
9256 messages from optionsTable when a port is not configured, added
9257 support for the PIc16 port in the ports table, when executing
9258 the compiler with no port specified on command line, a default
9259 port is selected with the new macro DEFAULT_PORT which is
9260 defined in port.h, in setDefaultOptions() linkOptions is removed
9261 from initialization assignment, since now it is a set,
9262 parseCmdLine uses setParseWithComma for linkOptions, in
9263 linkEdit() linkOptions are accessed with new function indexSet()
9264 which returns the i'th item of a set variable. See SDCCset.c, in
9265 linkEdit() when calling buildCmdLine(), added linkOptions as
9266 last argument. Now users can pass arguments to gplink via the
9267 -Wl option, main() uses pic16glue() to glue up pic16 programs

9279 * src/pic16/glue.c: commented out some error producing lines
9280 * src/pic16/main.c: __config directives are commented out to stop
9281 gpasm complaining and test the linkage with gplink, _linkCmd and
9282 _asmCmd changed to be more gplink and gpasm friendly
9283 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9284 produced an error when parsed, peep rule 12 is added to utilize
9285 movff, but it is commented out since the pCode does not support
9286 yet a command with 2 address arguments
9288 2003-05-18 <johan AT balder>
9290 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9317 2003-05-11 Borut Razem <borut.razem AT siol.net>
9319 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9320 the path of bin directory, so that PATH is the only env. variable, which has to be set
9321 in case of standard installation.
9322 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10377 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10378 multiple times and emitting the fetch operations more than once
10379 added aopGetUsesAcc() function to allow binary operators to
10380 fetch their operands in the correct order; made genMinus() emit
10381 compact code for X = LITERAL - Y
10383 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10384 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10385 sprintf() in line 1267.
10387 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10388 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10391 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10392 Changes to aslink (All the changes are marked with 'JCF'):
10394 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10397 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10398 area BSEG. Also moves, if possible, the DATA area down into the internal
10399 ram so more space is available.
10401 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10404 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10405 not bytes. Function summary() which creates a memory usage summary
10406 file with extension .mem. Reports of overlaping stack and small stack
10407 size. If the space for the stack is less than 16 bytes aslink trows a
10410 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10411 the 8051. Option 'y' for memory summary output file.
10413 Changes to sdcc (All the changes are marked with 'JCF'):
10415 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10417 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10418 overlaying area for it (uses RegBankUsed[4]).
10420 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10421 bank zero as used by default. By default aslink locates the stack
10422 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10423 the creation of the .mem file. Delegates the allocation of data area
10424 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10425 the begining of the stack area to aslink.
10427 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10428 glue() in SDCCglue.c creates an area for it.
10430 2002-09-03 Borut Razem <borut.razem AT siol.net>
10431 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10432 sdcc/src/pic/glue.c:
10433 introduced atexit() handler for teporay files removal in case of
10434 errors, assertions, ...
10436 2002-08-29 Borut Razem <borut.razem AT siol.net>
10437 * sdcc/support/cpp2/auto-host_vc_in.h:
10438 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10439 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10440 Maybe there is a similar problem with BORLANDC? It should be checked!
10442 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10443 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10444 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10445 was not executed, and the compiler (cl) launched a warning:
10446 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10448 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10449 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10451 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10452 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10454 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10455 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10456 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10457 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10458 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10459 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10460 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10461 - added Release configuration in VS projects
10462 - review of compiler an linker options
10463 - VC .exe files are generated in bin_vc directory, not to interfere
10464 with binaries generated from other projects (cygwin, mingw, bcc ...)
10466 * sdcc/src/yacc.dsp: added
10468 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10469 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10470 and insert the version number definitions from .version
10472 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10474 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10475 added - genarate auto-host.h using auto-host_vc_in.h as template
10478 removed from CVS, generated automatically
10480 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10481 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10483 2002-08-11 Borut Razem <borut.razem AT siol.net>
10484 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10486 2002-08-10 Borut Razem <borut.razem AT siol.net>
10487 * src/SDCCmain.c (main):
10488 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10489 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10490 The consequence was that some temporary files were not removed.
10493 unification of code in functions tempfilename() and tempfile():
10494 function tempnam() is defined in Visual Studio 6.0 and .NET
10496 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10498 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10499 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10500 - removed compiler command line option /WX: Treats all warnings as errors
10501 - update a list of source files, included into the project
10503 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10504 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10505 changed project type to Generic Project so that can be correcly converted to VS.NET project
10507 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10509 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10511 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10513 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10514 added return 0 statements after assert() to make compiler happy
10516 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10517 added newline in the def file to keep MSC compiler satisfied
10519 * sdcc/src/z80/gen.c:
10520 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10521 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10522 - solved MSC error in function aopDump()
10524 * sdcc_vc.h: define PREFIX as "\\sdcc"
10526 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10527 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10530 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10531 - Rewrote the register banking algorithm.
10532 - Added pCode live-range analysis to registers (for now, only non-used and
10533 singly-used registers optimized away)
10535 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10537 * 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.

10564 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10566 2002-03-28 Johan Knol <johan AT balder>
10568 * src/SDCCval.c: fixed bug #532436
10570 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10572 Added "char *Processor" field to the port structure.
10575 Added -p option. Allows port dependent processor to be specified.
10578 Initialized the new field char *Processor field to NULL in all ports
10581 Compiler generated registers for interrupt context saving
10582 were not getting allocated.
10584 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10587 Fixed left shift. Will promote the left side of a left shift
10588 if a) left shifting more than size of operand or b) when assigned
10589 to something size > size of left side
10591 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10593 tons of changes. Register allocation has been

10595 analysis is restructured. ...
10597 * src/pic/device.h:
10600 * src/pic/device.c:
10601 Added. device.c is a PIC port hack to accomodate variations
10604 2002-03-13 Michael Hope <michaelh AT vroom>
10606 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10608 2002-03-04 johanknol <johanknol AT manik>
10610 * /src/SDCCval.c: fixed
10612 const unsigned char arr[][2] = { { 0, 1 } };

10699 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10701 * sdcc/src/SDCCloop.c:
10702 Previous fix was not good. basic blocks that have "break" or "return" are
10703 not really partof a loop , but live ranges used in these blocks should
10704 be live thru the entire loop, so set partOfLoop but don't add them to
10707 2002-02-21 <johan AT FRIJA>
10709 * src/SDCCcse.c: fixed bug #514308
10711 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10714 Fixed BUG #519583. If a conditional block ended in a return/break
10715 statement inside a loop, it was not being considered part of the loop.
10717 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10719 2002-02-10 Karl Bongers <karl AT turbobit.com>
