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

794 (genCritical, genEndCritical): added functions
795 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
796 * src/z80/mappings.i: added "ei" to all mappings

808 the left operand is shorter than the result (c* = lit-c* + int),
810 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
813 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
815 * src/.version: increased version number to 2.5.5

817 linking is done manually in pic16 port's _linkEdit,
818 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
819 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

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

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

921 (commented out for reference), didn't account for some registers which
922 were left marked 'not free' after a pointer operation. The change
923 reduces register usage a lot in some cases

3196 * src/SDCCglobal.h (struct options),
3198 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3199 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3200 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3201 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3202 always available in leading double underscore form. The C99 support is
3203 mostly missing, but it's a start.
3204 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3205 reserved identifier "__data".
3207 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3283 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3285 * device/lib/printf_large.c: removed inline assembly for portability and
3286 readability. Use printf_fast if speed or size are more important.
3287 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3288 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3290 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3292 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3293 prevent compiler warning
3295 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3297 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3298 moved to level 0 and declared as static. Also they are explicit
3299 placed in access bank. This was necessery because some times they
3300 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3301 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3302 optimizations. Currently only compare to unsigned char is implemented,
3303 * src/pic16/gen.c: added fReturnIdx array,
3304 * (struct resolvedIfx) is moved to gen.h and made public,
3305 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3306 * (aopForSym): added an optimization to directly store in stack of
3307 the operand of a SEND iCode,
3308 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3309 but as registers instead (AOP_REG) using the fReturnIdx array,
3310 * (pic16_freeAsmop): remove the freed register from the
3311 _G.sregsAlloc field,
3312 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3313 a compare of 'WREG',
3314 * (pic16_popGetTempRegCond): changed function prototype, now
3315 function takes also a bitVector argument v which holds the current
3316 set of registers that are allocated for stack access by aopForSym,
3317 registers allocated in aopForSym for accessing stack symbols are not
3318 any more part of the functions usedRegs field,
3319 * (genCall): some times aopOp is called for a stack variable to be
3320 send, aopForSym might perform the push, if this is true make sure
3321 that genCall doesn't push the variable twice by testing _G.resDirect,
3322 * (genFunction): changed testing for unspecified interrupt number
3323 from 256 to INTNO_UNSPEC,
3324 * modified selection scheme of frame pointer generation. Previously
3325 if function did use local registers a frame pointer was generated,
3326 now a frame pointer is generated only if function has arguments
3327 (that need PLUSW2 register access), or has stack arguments, or the
3328 compiler is not instructed to omit the frame pointer,
3329 * (genEndFunction): before restoring local registers that were saved
3330 in the function preamble, also restore the registers that *might*
3331 have been allocated for stack access,
3332 * (genRet): removed some old comments,
3333 * (genCmp, the active (RN's) version): added a call to the
3334 pic16_genCmp_special function to perform the compare with a more
3335 robust and optimized way,
3336 * (genInline): a feature has been added in inline code generation,
3337 which allows a wildcard variable substitution when writing inline
3338 assembly. Code is incomplete and experimental therefore undocumented,
3339 * (genCast): changed order of aopOp for result and right to allow
3340 aopForSym to directly load the result if possible,
3341 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3342 perform an optimized compare on some selected special occasions,
3343 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3344 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3345 generate an IVT any more,
3346 * src/pic16/main.c (pic16_optionsTable): added command line option
3348 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3349 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3351 * src/pic16/NOTES: Raphael Neider added in list of active developers
3352 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3353 jumptable_end to prevent bug #,
3354 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3355 inCond and outCond fields,
3356 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3357 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3358 turn off register spilling,
3359 * (packRegsForOneUse): synced with other ports' versions although it
3360 is not used currently,
3361 * (pic16_packRegisters): added an optimization while reading
3362 structure bitfields, some registers may be saved (malloc code is
3363 decreased by 80 bytes)
3365 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3367 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3368 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3369 this can be optimized more?
3371 2005-03-10 Raphael Neider <rneider AT web.de>
3373 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3374 genNearPointerGet): (hopefully) fixed access to bitfields via
3375 pointers (p->bitN = x; and x = p->bitN; failed)

3420 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3421 to keep the correct label reference count when adding/removing references
3422 to labels. A peephole file using this is appended to patch #1144962.

4009 Adding support for replacing ljmps with sjmps in jumptables
4010 generated for switch statements. For now you need to set the
4011 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4012 Now 4 algorithms for mcs51 jumptable generation are used:
4013 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4014 addresses loaded pc-relative for up to 112 cases and stack-pushing
4015 target addresses loaded with offset from dptr for up to 256 cases.

4045 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4047 * added libc directory. The current version of LibC contains string
4048 functions, ctype functions and macros and some functions of the
4049 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4050 be extensively tested in the future. Standard disclaimer here.
4051 Library is not automatically build yet. But one can build it by
4052 invoking 'make' inside the libc directory.

4063 * (pic16_storeForReturn): optimized return of 0,
4064 * (genCmp): experimental code for new genCmp which uses PIC18's
4065 special compare&skip instructions. Initial tests fail some times
4066 with variables grater than 1 byte in size, so new code is disabled,
4067 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4069 * (genCast): began a fix to optimize the casting of a bit to another
4070 bit, now assigning a bitfield to another bitfield will fail, sorry,

4081 caused stop processing pCodes after a inline assembly block,
4082 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4084 registers when it shouldn't,
4085 * src/pic16/ralloc.c (allocReg): add preliminary support for
4086 supporting a limited set of temporary registers,
4088 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6976 2004-01-27 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6978 * ChangeLog: changed "@" to " AT " in hopes of reducing spam and
6979 virus/worm forged address usage.
6981 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
6983 Fixed promotion, it should be done on AST level:
6984 * src/SDCCast.c (addCast): added promotion to int
6985 (decorateType): updated call to upCast()
6986 * src/SDCCicode.c (geniCodeLeftShift): removed call to
6987 usualUnaryConversions()
6989 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
6991 * support/regression/tests/literalop.c (mulWrapper): Added a
6992 wrapper to remove integer overflow warnings.

6996 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
6999 * support/regression/generate-cases.py (main): Changed from inline
7002 * doc/Makefile (install): Changed to depth first to get rid of
7003 missing directory install warning.
7005 * as/Makefile (install-doc): Made work on Mac.
7007 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
7009 * src/SDCCast.c: added an additional type flow in decorateType() of
7010 opposite direction, see feature request #860006; it's enabled at runtime
7011 by setting the environment variable SDCC_NEWTYPEFLOW
7012 * src/SDCCast.h: changed prototype of decorateType()
7013 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
7014 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
7015 'char' to 'int' can be omitted, if both operands are 'unsigned char';
7016 see feature request #877103
7017 * src/SDCCval.c: updated call of decorateType()
7018 (valBitwise): fixed bug #882876
7019 (valMinus): added promotion
7020 (valLogicAndOr): result is unsigned
7021 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
7022 * src/SDCCsymt.c (computeType),
7023 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
7024 must not cause an unsigned operation

7045 * src/pic/ralloc.h: applied patch from Slade Rich;
7046 added support for multiple code pages and multiple RAM banks on the
7047 PIC 14 port. The ASM files now no longer simply assume all the
7048 code / RAM are in the same page / bank. This means the linker can
7049 safely allocate code/RAM of separate ASM files to different pages/banks.
7050 * doc/sdccman.lyx: added Slade's tips
7051 * src/mcs51/peeph.def: fixed bug #880768

7063 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7064 strtof is not part of C89 and isn't included with Mac OS X.
7066 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7068 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7093 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7095 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7096 loaded with the linker search paths (-L arguments) and the libraries
7097 to be linked with the current source (-l arguments). Changes
7098 currently will affect only the pic16 port.
7099 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7100 include path the port specific paths and port specific libraries,
7101 * gplink command now contains the $3 argument,
7102 * src/pic16/device.h,
7103 * src/pic16/device.c,: structure PIC_device is made public and
7104 renamed to PIC16_device, the same for variable Pics which is renamed

7119 Documenting changes from previous commits.
7120 * configure.in (version 1.56),
7121 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7122 when generating output files to configure the pic16 library,
7123 but now I've commented it out, since gputils aren't installed in the
7124 SF compile farm, so library won't compile
7126 * device/lib/Makefile.in (version 1.56): initially I've added in
7127 target 'all' the prerequestive 'model-pic16' so it compiled the
7128 pic16 library, but now I've commented it out for the same reasons
7130 * added targets 'model-pic16' and 'objects-pic16' to compile the
7132 * added target 'port-specific-objects-pic16' to handle the
7133 generated libraries and copy them into the build/ directory
7134 * added target 'clean-intermediate-pic16' to clean intermediate
7135 files into pic16 directory
7136 * in target 'installdirs' added line to create directory pic16 in
7137 the installation path
7139 * device/include/Makefile.in (version 1.11): in target 'install'
7140 added lines to copy all header files to installation path,
7141 * in target 'installdirs' added line create directory for pic16
7142 headers in the installation path

7157 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7158 option so that it actually works. Made it specific to the z80, since
7159 the gbz80 doesn't have these kinds of I/O ports.
7161 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7163 * device/include/z180.h,

7185 Mainly changes to support compilation of the device libraries
7186 * src/pic16/device.c: stack is allocated via symbol and not
7187 via literal number. The symbol is placed in the corresponding
7188 position of the data ram
7189 * (pic16_dump_section): relocatable and absolute uninitialized
7190 data are now emitted in sorted order to reduce section naming,
7191 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7192 weren't marked as being in the access bank,
7194 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7196 Added portion of GNU PIC Library under the directory
7197 device/include/pic16 and device/lib/pic16. These files
7198 contain the declarations of SFRs for the PIC18Fxx2 devices.
7199 The directory is initialized via configure from toplevel.
7201 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7203 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

7229 all over. Telling LaTeX to be less strict with word spacing
7230 to better keep the right margin. Changed some notes about
7231 maintainance of the ports in section 3.2.1 - is it OK like this?
7233 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7271 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7273 * src/pic16/peeph.def: all peepholes with movff are commented out,
7274 because there is a problem in the pcode peep optimizer,
7275 * src/pic16/ralloc.c: the register allocator can now reuse local

7277 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7279 Added file src/pic16/NOTES with information about program writing on
7280 the current port version.

7340 directive when no overlay data exist
7341 * (picglue): modified to emit uninitialized data segment
7342 according to udata_section_name

7414 Bug reported from Jesus Calvino-Fraga
7416 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7418 * sdcc.spec: updated
7419 * device/include/Makefile.in: don't install CVS directories

7427 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7429 PIC16 port related changes:
7430 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7431 added variable stackPos,
7433 * gen.c: genCall, assignResultValue: added support for
7434 pushing/retrieving function parameters to/from stack,
7435 genFunction,genEndFunction: setup stack frame for the
7437 genAddrOf: will be changed according to bug 863624
7439 * added files genutils.c and genutils.h which contain gen*
7440 debugged and optimised functions extracted from gen.c
7442 * glue.c: added variable 'externs' which holds extern symbols,
7443 pic16emitRegularMap: is modified to properly handle relocatable
7444 symbols under the new scheme,
7445 pic16createInterruptVect: is modified
7446 pic16printPublics: is modified to emit 'global' assembler directives,
7447 added pic16_printExterns to print extern symbols,
7448 pic16glue: initializes stack/frame pointer in the beginning of
7449 the assembly output. Temporary hack, will be corrected later,
7450 because gplink yet does not support stack and SDCC does not
7451 yet support a type of crt0.o object to create the final binary.
7453 * Removed many lines that contain 8051 legacy code.
7454 * The code is finally placed under a 'code' directive.
7455 * Added port specific options.
7457 * _process_pragma: simplified since now we do not need *special*
7458 include file to define SFR registers. But a separate header
7459 will be needed. This will be developed later.
7460 * _pic16_parseOptions: added, parses port specific options:
7461 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7462 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7463 --preplace-udata-with=
7465 * _pic16_setDefaultOptions: modified to initialize section names,
7466 but hack is temporarly out of order since it needs improvement.
7467 * _pic16_genAssemblerPreamble: configuration words are emitted by
7468 their address instead of their name. This part is incomplete and
7469 supports only the 18Fxx2 devices. Other devices will emit an error
7470 during assembly since they do not contain the same set of config
7472 * _pic16_genIVT: is modified,
7474 * pcode.c: added definitions for some hardware registers that are needed
7476 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7477 All PCI entries are updated. Now LFSR is supported.
7478 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7479 * added pic16_newpCodeOpLit2 to support instructions with
7480 two literal arguments
7481 * pic16_pCode2str: corrected code that emits assembler instructions
7482 with two literal operands and those that have an access bit modifier
7483 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7484 this fixes a bug which caused some labels to be lost, when an
7485 assembler directive was added, i.e. banksel,
7486 * pic16_FixRegisterBanking: improved logic that causes the insertion
7488 * InlineFunction: functions that are called once, are not any more
7489 inlined. This can be a port option in the future,
7491 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7493 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7494 hold the corresponding uninitialized symbols,
7495 * pic16_allocProcessorRegister: registers have explicit marked the
7497 * pic16_allocInternalRegister: registers are explicit marked as
7499 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7500 processing list, so bit registers were lost,
7503 * ralloc.h: added field 'accessBank' and original symbol operand
7504 in register definition,
7505 * removed the field isMapped from register definition,
7507 ** Several functions have been removed from various sources:
7508 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7509 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7510 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7511 pic16_assignRelocatableRegisters
7513 ** others have been introduced:
7514 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7515 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7517 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7519 * support/scripts/inc2h.pl: changed definition of BIT_AT
7520 to emit 'sbit at' instead of 'bit at'. This was a request.
7522 PIC16 port related preliminary changes:
7523 * gen.c: prefixed function popRegFromString with
7524 pic16_ and all references to it corrected
7525 * pcode.c: all pic16_pc_* hardware registers prefixed
7526 with underscore (_),
7527 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7528 * ralloc.c: newReg(): when register is REG_SFR then
7529 set address to rIdx,
7530 pic16_allocProcessorRegister(): marks register wasUsed=0
7531 pic16_writeUsedRegs(): added a call to assign processor
7532 registers via pic16_assignFixedRegisters
7534 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7536 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7537 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7538 variables in unused register banks. Also the SSEG is placed
7539 wherever there is enough space for it, and IDATA can be anywhere
7540 in internal RAM. For now compile using -Wl-Y[stack_size].
7541 The mem file is different for this option as well, since it
7542 makes no sense of talking about DSEG lenght.
7544 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7546 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7547 in certain cases, e.g. when ROM assignment, patch provided
7548 from Albert den Haan.

7791 * src/SDCCast.c (decorateType): disabled a transformation I added in
7792 revision 1.188 (access to fields of a structure at an absolute address);
7793 it breaks with bitfields, extern declarations, and gcse analysis.
7794 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7795 could be assigned through a pointer, so don't complain.

7903 xdata initialization slightly shorter
7905 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8551 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8552 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8553 fetching of the pointer
8554 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8555 copied from genNearPointerSet()
8556 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8557 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8573 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8574 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8575 type for bits was changed. It resulted in bit variables becoming
8576 global, which is not permitted in PIC 14 assembly output.
8578 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8580 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8593 A few small changes that speed up the peephole optimizer.
8597 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8599 Try to make the peephole optimizer smarter by maintaining
8600 an association between the assembly source code and the
8601 iCodes that originated them. Put this information to use
8602 with a new peephole rule condition "notVolatile" so that
8603 the rules can be aggressive yet still safe.
8608 * src/mcs51/peeph.def
8610 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8614 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8615 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8616 if the left or right operand symbols have the accuse flag set.
8618 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8620 Changed the type of the result of the ! (NOT) operator to char;
8621 previously it returned the same type as the source. This allows
8622 us to eliminate all the genFloatNot functions (all of its target
8623 implementations were very buggy) since !float can use the same
8626 * src/SDCCicode.c (ast2iCode): ! returns char

8628 * src/ds390/gen.c (genNot, genNotFloat),
8629 * src/z80/gen.c (genNot, genNotFloat),
8630 * src/pic/gen.c (genNot, genNotFloat),

8635 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8636 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8637 during interrupts. Ensure WSAVE is located at a shared bank address.
8638 2. Fixed page selection in some places
8639 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8640 the registers name strings.
8641 4. Fixed "signed / unsigned compare" compiler warnings.
8642 5. The PIC port manages its own allocation of the general purpose
8643 registers, but makes no attempt to reuse them. As a result when
8644 compiling it soon runs out of general purpose registers. Some
8645 additional code was added to the files pcode.c and device.c to walk
8646 through the function call tree and rename the registers so that they
8656 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8657 genPlus() & genMinus() when the result is the same as left or right

8663 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8665 Made bitfield a distinct type from bit so that bitfields
8666 convert as per ANSI C and bits retain their traditional
8667 boolean style behaviour. Implemented bitfield support in
8675 * src/ds390/gen.c: bit v bitfield split
8676 * src/z80/gen.c: New support for bitfields
8677 * support/regression/tests/bitfields.c: reenabled z80,
8680 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8682 Rules 246.x, 247.x relate to bitfields, the others speed up
8683 access to xdata mapped I/O devices.
8685 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8687 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8689 Cleaned up genPackBits and genUnpackBits and added two helper
8690 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8691 for literal assignments in genPackBits (thanks to Frieder for
8697 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8699 Fixed bug #748310 (pointer to function type mishandled when the
8700 function name is omitted). Also fixed a SIGSEGV when a function
8701 attribute (reentrant, etc) is used on a non-function or on a
8702 function but misplaced before the parameter list.
8704 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8706 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8707 * support/Util/SDCCerr.h,
8708 * support/Util/SDCCerr.c: Added func attr misuse error msg

8729 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8731 Made the constant following the "interrupt" keyword optional. If
8732 omitted, the function will not automatically be given an entry
8733 in the interrupt vector table (similar to #pragma NOIV, but
8734 less syntacticly kludgy). The interrupt number is also now
8735 range checked. Also fixed a bug in the high order bit example
8742 * support/Util/SDCCerr.c
8743 * support/Util/SDCCerr.h
8746 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8748 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
8749 * src/SDCCicode.c (operandOperation): rewritten some ops
8750 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8751 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8753 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8754 be re-activated by defining REDUCE_LITERALS)
8755 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8756 unsigned, but are signed by default
8757 * src/SDCCval.c (constVal): rearranged
8758 * src/SDCCval.c (valMod): preliminary fix
8759 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8801 constants are unsigned; added recognition of "u" flag for unsigned
8802 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8803 * src/SDCCval.c (valDiv, valMod): fixed signdness
8804 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8805 signedness of modulo, left and right shift

9264 * src/SDCCmain.c: linkOptions is changed to set *,
9265 added if/endif conditional macros to remove options help
9266 messages from optionsTable when a port is not configured, added
9267 support for the PIc16 port in the ports table, when executing
9268 the compiler with no port specified on command line, a default
9269 port is selected with the new macro DEFAULT_PORT which is
9270 defined in port.h, in setDefaultOptions() linkOptions is removed
9271 from initialization assignment, since now it is a set,
9272 parseCmdLine uses setParseWithComma for linkOptions, in
9273 linkEdit() linkOptions are accessed with new function indexSet()
9274 which returns the i'th item of a set variable. See SDCCset.c, in
9275 linkEdit() when calling buildCmdLine(), added linkOptions as
9276 last argument. Now users can pass arguments to gplink via the
9277 -Wl option, main() uses pic16glue() to glue up pic16 programs

9289 * src/pic16/glue.c: commented out some error producing lines
9290 * src/pic16/main.c: __config directives are commented out to stop
9291 gpasm complaining and test the linkage with gplink, _linkCmd and
9292 _asmCmd changed to be more gplink and gpasm friendly
9293 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9294 produced an error when parsed, peep rule 12 is added to utilize
9295 movff, but it is commented out since the pCode does not support
9296 yet a command with 2 address arguments
9298 2003-05-18 <johan AT balder>
9300 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9327 2003-05-11 Borut Razem <borut.razem AT siol.net>
9329 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9330 the path of bin directory, so that PATH is the only env. variable, which has to be set
9331 in case of standard installation.
9332 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10372 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10374 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10375 value from option --iram-size.
10377 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10379 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10382 2002-09-18 <wiml AT hhhh.org>
10384 * SDCClrange.h: exposed setFromRange() and setToRange()
10385 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10386 packRegsForAccUse() (bug 542397)
10387 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10388 multiple times and emitting the fetch operations more than once
10389 added aopGetUsesAcc() function to allow binary operators to
10390 fetch their operands in the correct order; made genMinus() emit
10391 compact code for X = LITERAL - Y
10393 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10394 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10395 sprintf() in line 1267.
10397 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10398 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10401 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10402 Changes to aslink (All the changes are marked with 'JCF'):
10404 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10407 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10408 area BSEG. Also moves, if possible, the DATA area down into the internal
10409 ram so more space is available.
10411 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10414 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10415 not bytes. Function summary() which creates a memory usage summary
10416 file with extension .mem. Reports of overlaping stack and small stack
10417 size. If the space for the stack is less than 16 bytes aslink trows a
10420 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10421 the 8051. Option 'y' for memory summary output file.
10423 Changes to sdcc (All the changes are marked with 'JCF'):
10425 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10427 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10428 overlaying area for it (uses RegBankUsed[4]).
10430 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10431 bank zero as used by default. By default aslink locates the stack
10432 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10433 the creation of the .mem file. Delegates the allocation of data area
10434 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10435 the begining of the stack area to aslink.
10437 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10438 glue() in SDCCglue.c creates an area for it.
10440 2002-09-03 Borut Razem <borut.razem AT siol.net>
10441 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10442 sdcc/src/pic/glue.c:
10443 introduced atexit() handler for teporay files removal in case of
10444 errors, assertions, ...
10446 2002-08-29 Borut Razem <borut.razem AT siol.net>
10447 * sdcc/support/cpp2/auto-host_vc_in.h:
10448 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10449 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10450 Maybe there is a similar problem with BORLANDC? It should be checked!
10452 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10453 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10454 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10455 was not executed, and the compiler (cl) launched a warning:
10456 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10458 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10459 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10461 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10462 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10464 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10465 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10466 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10467 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10468 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10469 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10470 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10471 - added Release configuration in VS projects
10472 - review of compiler an linker options
10473 - VC .exe files are generated in bin_vc directory, not to interfere
10474 with binaries generated from other projects (cygwin, mingw, bcc ...)
10476 * sdcc/src/yacc.dsp: added
10478 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10479 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10480 and insert the version number definitions from .version
10482 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10484 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10485 added - genarate auto-host.h using auto-host_vc_in.h as template
10488 removed from CVS, generated automatically
10490 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10491 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10493 2002-08-11 Borut Razem <borut.razem AT siol.net>
10494 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10496 2002-08-10 Borut Razem <borut.razem AT siol.net>
10497 * src/SDCCmain.c (main):
10498 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10499 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10500 The consequence was that some temporary files were not removed.
10503 unification of code in functions tempfilename() and tempfile():
10504 function tempnam() is defined in Visual Studio 6.0 and .NET
10506 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10508 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10509 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10510 - removed compiler command line option /WX: Treats all warnings as errors
10511 - update a list of source files, included into the project
10513 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10514 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10515 changed project type to Generic Project so that can be correcly converted to VS.NET project
10517 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10519 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10521 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10523 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10524 added return 0 statements after assert() to make compiler happy
10526 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10527 added newline in the def file to keep MSC compiler satisfied
10529 * sdcc/src/z80/gen.c:
10530 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10531 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10532 - solved MSC error in function aopDump()
10534 * sdcc_vc.h: define PREFIX as "\\sdcc"
10536 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10537 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10540 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10541 - Rewrote the register banking algorithm.
10542 - Added pCode live-range analysis to registers (for now, only non-used and
10543 singly-used registers optimized away)
10545 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10547 * 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.

10572 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10574 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10576 2002-03-28 Johan Knol <johan AT balder>
10578 * src/SDCCval.c: fixed bug #532436
10580 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10582 Added "char *Processor" field to the port structure.
10585 Added -p option. Allows port dependent processor to be specified.
10588 Initialized the new field char *Processor field to NULL in all ports
10591 Compiler generated registers for interrupt context saving
10592 were not getting allocated.
10594 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10597 Fixed left shift. Will promote the left side of a left shift
10598 if a) left shifting more than size of operand or b) when assigned
10599 to something size > size of left side
10601 2002-03-14 Scott Dattalo <scott AT dattalo.com>

10605 analysis is restructured. ...
10607 * src/pic/device.h:
10610 * src/pic/device.c:
10611 Added. device.c is a PIC port hack to accomodate variations
10614 2002-03-13 Michael Hope <michaelh AT vroom>
10616 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10618 2002-03-04 johanknol <johanknol AT manik>
10620 * /src/SDCCval.c: fixed
10622 const unsigned char arr[][2] = { { 0, 1 } };

10709 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10711 * sdcc/src/SDCCloop.c:
10712 Previous fix was not good. basic blocks that have "break" or "return" are
10713 not really partof a loop , but live ranges used in these blocks should
10714 be live thru the entire loop, so set partOfLoop but don't add them to
10717 2002-02-21 <johan AT FRIJA>
10719 * src/SDCCcse.c: fixed bug #514308
10721 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10724 Fixed BUG #519583. If a conditional block ended in a return/break
10725 statement inside a loop, it was not being considered part of the loop.
10727 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10729 2002-02-10 Karl Bongers <karl AT turbobit.com>
