1187 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1189 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1190 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1192 One basic decision: e.g. src/clean.mk includes further files. In order
1193 to make this work there are two solutions:
1194 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1195 run configure on them. This way they can use
1196 'include $(srcdir)/port-clean.mk'
1197 - always include clean.mk by the Makefile at the same level. To avoid
1198 that `make clean` tries to include and build Makefile.dep the
1199 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1200 implemented, because now even `make uninstall` doesn't create
1201 Makefile.in. clean.mk could be eliminated by pasting it in
1204 * debugger/mcs51/Makefile.in: build own objects from library sources
1205 (SLIB, SDCC) in current directory
1207 * configure, configure.in: renamed --disable-device-lib-build in
1208 --disable-device-lib; added --enable-doc, the required tools are
1209 searched by configure; added result message; the toolchain for the
1210 belonging ports are now only built, if the port is enabled.
1212 * support/regression/*: all output is written in directory gen, because
1213 the fwk and ports directories don't livet in the build tree using vpath
1215 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1216 --disable-device-lib, added --enable-doc, added section VPATH
1218 * sim/ucsim/configure.in,
1219 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1220 z80 are enabled by default
1222 2006-04-24 Raphael Neider <rneider AT web.de>
1224 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1225 to config word, "pic14_"-prefixed some extern functions
1226 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1227 config word has been found
1228 * src/pic/device.h: added prototypes
1229 * src/pic/pcode.c: added "pic14_"-prefix where needed

1232 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1470 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1472 * src/mcs51/gen.c (genCall): fixed bug 1457608
1474 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1493 implemented patch 1120823 Thanks to Willy De la Court (normal
1494 interrupts need an interrupt number now if they are made critical),
1495 and enabled nesting of critical functions though not for gbz80
1496 (genCritical, genEndCritical): added functions
1497 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1498 * src/z80/mappings.i: added "ei" to all mappings

1510 the left operand is shorter than the result (c* = lit-c* + int),
1512 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1515 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1517 * src/.version: increased version number to 2.5.5
1518 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1519 linking is done manually in pic16 port's _linkEdit,
1520 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1521 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1522 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1523 allocate asmop as AOP_ACC,
1524 (aopForRemat): added parameter 'bool result' in function declaration,
1525 (pic16_aopGet): return AOP_ACC when accessing WREG,
1526 (pic16_popGetTempReg): minor modification,

1537 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1538 call to allocReg, not by manually allocating a new one,
1539 (pic16_assignRegisters): now before going through the register
1540 allocating functions mark all registers as free. This eliminates some
1541 side effects resulting from peephole parser done earlier in the backbone
1543 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1601 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1602 which dumps before the function entry point a data byte which represents
1603 the number of the local variables used by the specified function, added
1604 'xinst' for initial support for Extended Instruction Support,
1605 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1606 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1607 port->fun_prefix anymore (may change later),
1608 (genFunction, genEndFunction): do not store/restore local registers for
1609 _main (this should take care the --main-return command line option in
1611 (genOr): removed some legacy pic-port instructions,
1612 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1613 performing operations with SFR's causes data to be written more than
1614 once to each SFR. Perhaps SFRs should be handled in special cases...
1615 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1617 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1618 into account for stack starting position,

1620 --extended or -y for Extended Instruction Support,
1621 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1622 (deassignLRs): *** perhaps the most important change, old 'for' code
1623 (commented out for reference), didn't account for some registers which
1624 were left marked 'not free' after a pointer operation. The change
1625 reduces register usage a lot in some cases

3876 where not placed in the same memory bank,
3877 * device/lib/pic16/libsdcc/char/: various modifications to improve
3878 library performance,

3889 if condition == CARRY)
3890 * (genCmp): adapted to new genSkipc semantics
3891 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
3892 on rIfx (genCmp was broken)
3894 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3896 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3897 * src/z80/main.c (_keywords[]),
3898 * src/SDCCglobal.h (struct options),
3900 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3901 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3902 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3903 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3904 always available in leading double underscore form. The C99 support is
3905 mostly missing, but it's a start.
3906 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3907 reserved identifier "__data".
3909 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3911 * src/mcs51/peeph.def: fixed bug 1170013
3913 2005-03-22 Maarten Brock <sourceforge.brock AT dse.nl>

3919 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
3922 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3924 * src/port.h (struct PORT),

3952 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3953 immedDom() returning wrong block; probably fixes bug #1160833)
3955 2005-03-20 Borut Razem <borut.razem AT siol.net>
3957 * support/scripts/inc2h.pl: WIN32 port
3959 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3961 * device/lib/makefile.in: added abs.c and labs.c
3963 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3965 * device/include/stdint.h: added
3966 * device/lib/abs.c: added
3967 * device/lib/labs.c: added
3968 * device/include/stdlib.h: added abs() and labs() prototypes

3985 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3987 * device/lib/printf_large.c: removed inline assembly for portability and
3988 readability. Use printf_fast if speed or size are more important.
3989 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3990 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3992 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3994 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3995 prevent compiler warning
3997 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3999 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4000 moved to level 0 and declared as static. Also they are explicit
4001 placed in access bank. This was necessery because some times they
4002 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4003 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4004 optimizations. Currently only compare to unsigned char is implemented,
4005 * src/pic16/gen.c: added fReturnIdx array,
4006 * (struct resolvedIfx) is moved to gen.h and made public,
4007 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4008 * (aopForSym): added an optimization to directly store in stack of
4009 the operand of a SEND iCode,
4010 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4011 but as registers instead (AOP_REG) using the fReturnIdx array,
4012 * (pic16_freeAsmop): remove the freed register from the
4013 _G.sregsAlloc field,
4014 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4015 a compare of 'WREG',
4016 * (pic16_popGetTempRegCond): changed function prototype, now
4017 function takes also a bitVector argument v which holds the current
4018 set of registers that are allocated for stack access by aopForSym,
4019 registers allocated in aopForSym for accessing stack symbols are not
4020 any more part of the functions usedRegs field,
4021 * (genCall): some times aopOp is called for a stack variable to be
4022 send, aopForSym might perform the push, if this is true make sure
4023 that genCall doesn't push the variable twice by testing _G.resDirect,
4024 * (genFunction): changed testing for unspecified interrupt number
4025 from 256 to INTNO_UNSPEC,
4026 * modified selection scheme of frame pointer generation. Previously
4027 if function did use local registers a frame pointer was generated,
4028 now a frame pointer is generated only if function has arguments
4029 (that need PLUSW2 register access), or has stack arguments, or the
4030 compiler is not instructed to omit the frame pointer,
4031 * (genEndFunction): before restoring local registers that were saved
4032 in the function preamble, also restore the registers that *might*
4033 have been allocated for stack access,
4034 * (genRet): removed some old comments,
4035 * (genCmp, the active (RN's) version): added a call to the
4036 pic16_genCmp_special function to perform the compare with a more
4037 robust and optimized way,
4038 * (genInline): a feature has been added in inline code generation,
4039 which allows a wildcard variable substitution when writing inline
4040 assembly. Code is incomplete and experimental therefore undocumented,
4041 * (genCast): changed order of aopOp for result and right to allow
4042 aopForSym to directly load the result if possible,
4043 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4044 perform an optimized compare on some selected special occasions,
4045 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4046 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4047 generate an IVT any more,
4048 * src/pic16/main.c (pic16_optionsTable): added command line option
4050 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4051 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4053 * src/pic16/NOTES: Raphael Neider added in list of active developers
4054 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4055 jumptable_end to prevent bug #,
4056 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4057 inCond and outCond fields,
4058 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4059 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4060 turn off register spilling,
4061 * (packRegsForOneUse): synced with other ports' versions although it
4062 is not used currently,
4063 * (pic16_packRegisters): added an optimization while reading
4064 structure bitfields, some registers may be saved (malloc code is
4065 decreased by 80 bytes)
4067 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4069 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4070 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4071 this can be optimized more?
4073 2005-03-10 Raphael Neider <rneider AT web.de>
4075 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4076 genNearPointerGet): (hopefully) fixed access to bitfields via
4077 pointers (p->bitN = x; and x = p->bitN; failed)
4079 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4265 of (byte sized) temporaries (assign them to WREG for now)
4266 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4267 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4268 this might fix SIGSEGVs on MinGW...
4269 * src/SDCCopt.c (killDeadCode): restored original behaviour
4270 (volatile operands might get thrown away though)
4272 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
4274 * src/pic16/gen.c: fixed bug #1106975,

4741 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
4743 Large cummulative patch for pic16 port.
4744 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4745 to call when a stack overflow occurs,
4746 * (malloc.h): added CVS Id tag,
4747 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4749 * added libc directory. The current version of LibC contains string
4750 functions, ctype functions and macros and some functions of the
4751 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4752 be extensively tested in the future. Standard disclaimer here.
4753 Library is not automatically build yet. But one can build it by
4754 invoking 'make' inside the libc directory.
4755 * added ADC library under libio. Preliminary version yet.
4757 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
4758 * src/pic16/gen.c (aopForRemat): asmop size is filled by
4759 aopForRemat() now and not by pic16_aopOp(),
4760 * (pic16_popGetTempReg): removed warning messgae when allocating
4761 temporary registers, its a buggy feature and will be removed,
4762 * (pic16_popGet): set register instance field in AOP_CRY,
4763 * (pic16_outBitC): fixed for results in size greater than 1,
4764 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4765 * (pic16_storeForReturn): optimized return of 0,
4766 * (genCmp): experimental code for new genCmp which uses PIC18's
4767 special compare&skip instructions. Initial tests fail some times
4768 with variables grater than 1 byte in size, so new code is disabled,
4769 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4771 * (genCast): began a fix to optimize the casting of a bit to another
4772 bit, now assigning a bitfield to another bitfield will fail, sorry,
4773 * src/pic16/main.c: disabled the use of lr-support feature,
4774 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4775 * added some function prototypes, added function _debugf prototype,
4776 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
4777 bits with offset (case PO_GPR_BIT),
4778 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4780 * (isBankInstruction): modified to return 0 for no banking instruction,
4781 and 1 for banking instruction,
4782 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4783 caused stop processing pCodes after a inline assembly block,
4784 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4785 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4786 registers when it shouldn't,
4787 * src/pic16/ralloc.c (allocReg): add preliminary support for
4788 supporting a limited set of temporary registers,
4790 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4792 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4793 genDataPointerSet): ensure assignments always copy in MSB to LSB
4795 (loadRegFromAop): recognize CLRH optimization,
4796 (genFunction): optimize RECEIVE iCodes in reentrant functions
4798 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4800 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4801 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4803 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08
4804 * src/hc08/main.c (_hc08_setDefaultOptions): default xdata to be
4805 contiguous with data

4809 * device/lib/_gptrget.c (_gptrget),
4810 * device/lib/_gptrgetc.c (_gptrgetc),
4811 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
4812 instead of sjmp to ret
4813 * src/mcs51/peeph.def: added peepholes 3.d-g and 177.g,h provided
4814 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks
4816 2004-11-18 Maarten Brock <sourceforge.brock AT dse.nl>

7795 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7797 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7798 loaded with the linker search paths (-L arguments) and the libraries
7799 to be linked with the current source (-l arguments). Changes
7800 currently will affect only the pic16 port.
7801 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7802 include path the port specific paths and port specific libraries,
7803 * gplink command now contains the $3 argument,
7804 * src/pic16/device.h,
7805 * src/pic16/device.c,: structure PIC_device is made public and
7806 renamed to PIC16_device, the same for variable Pics which is renamed

7821 Documenting changes from previous commits.
7822 * configure.in (version 1.56),
7823 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7824 when generating output files to configure the pic16 library,
7825 but now I've commented it out, since gputils aren't installed in the
7826 SF compile farm, so library won't compile
7828 * device/lib/Makefile.in (version 1.56): initially I've added in
7829 target 'all' the prerequestive 'model-pic16' so it compiled the
7830 pic16 library, but now I've commented it out for the same reasons
7832 * added targets 'model-pic16' and 'objects-pic16' to compile the
7834 * added target 'port-specific-objects-pic16' to handle the
7835 generated libraries and copy them into the build/ directory
7836 * added target 'clean-intermediate-pic16' to clean intermediate
7837 files into pic16 directory
7838 * in target 'installdirs' added line to create directory pic16 in

7889 via literal number. The symbol is placed in the corresponding
7890 position of the data ram
7891 * (pic16_dump_section): relocatable and absolute uninitialized
7892 data are now emitted in sorted order to reduce section naming,
7893 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7894 weren't marked as being in the access bank,
7896 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7898 Added portion of GNU PIC Library under the directory
7899 device/include/pic16 and device/lib/pic16. These files
7900 contain the declarations of SFRs for the PIC18Fxx2 devices.

7931 all over. Telling LaTeX to be less strict with word spacing
7932 to better keep the right margin. Changed some notes about
7933 maintainance of the ports in section 3.2.1 - is it OK like this?
7935 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7975 * src/pic16/peeph.def: all peepholes with movff are commented out,
7976 because there is a problem in the pcode peep optimizer,
7977 * src/pic16/ralloc.c: the register allocator can now reuse local

8014 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8017 * src/z80/main.c: added missed needLinkerScript flags (more than
8018 one port structure defined in these file)
8019 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

8054 2004-01-07 Borut Razem <borut.razem AT siol.net>
8056 * support/scripts/sdcc.nsi: update PATH
8057 * support/scripts/sdcc.ico: craeted

8070 include information about variables allocated to the overlay
8073 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8075 * as/mcs51/lkmain.c: Help about -Y option

8087 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8089 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8090 (default behaviour).
8092 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8094 A python script to validate compiler diagnostic messages. It can be
8095 used to verify that sdcc complains about bad c source code and
8096 gives a good location of the error.
8097 * support/valdiag/Makefile,
8098 * support/valdiag/valdiag.py,
8099 * support/valdiag/tests/*
8101 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8114 * src/common.h: added ifndef/define/endif macros
8115 around the header file.
8116 Bug reported from Jesus Calvino-Fraga
8118 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8120 * sdcc.spec: updated
8121 * device/include/Makefile.in: don't install CVS directories
8122 * device/lib/Makefile.in: added removal of CVS directories after install
8123 * doc/Makefile: fixed install, added local_icons
8124 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8125 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8126 * src/ds390/gen.c (genRightShift): fixed bug #870788
8127 * src/SDCCast.c (decorateType): fixed bug #870781
8129 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8131 PIC16 port related changes:
8132 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8133 added variable stackPos,
8135 * gen.c: genCall, assignResultValue: added support for
8136 pushing/retrieving function parameters to/from stack,
8137 genFunction,genEndFunction: setup stack frame for the
8139 genAddrOf: will be changed according to bug 863624
8141 * added files genutils.c and genutils.h which contain gen*
8142 debugged and optimised functions extracted from gen.c
8144 * glue.c: added variable 'externs' which holds extern symbols,
8145 pic16emitRegularMap: is modified to properly handle relocatable
8146 symbols under the new scheme,
8147 pic16createInterruptVect: is modified
8148 pic16printPublics: is modified to emit 'global' assembler directives,
8149 added pic16_printExterns to print extern symbols,
8150 pic16glue: initializes stack/frame pointer in the beginning of
8151 the assembly output. Temporary hack, will be corrected later,
8152 because gplink yet does not support stack and SDCC does not
8153 yet support a type of crt0.o object to create the final binary.
8155 * Removed many lines that contain 8051 legacy code.
8156 * The code is finally placed under a 'code' directive.
8157 * Added port specific options.
8159 * _process_pragma: simplified since now we do not need *special*
8160 include file to define SFR registers. But a separate header
8161 will be needed. This will be developed later.
8162 * _pic16_parseOptions: added, parses port specific options:
8163 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8164 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8165 --preplace-udata-with=
8167 * _pic16_setDefaultOptions: modified to initialize section names,
8168 but hack is temporarly out of order since it needs improvement.
8169 * _pic16_genAssemblerPreamble: configuration words are emitted by
8170 their address instead of their name. This part is incomplete and
8171 supports only the 18Fxx2 devices. Other devices will emit an error
8172 during assembly since they do not contain the same set of config
8174 * _pic16_genIVT: is modified,
8176 * pcode.c: added definitions for some hardware registers that are needed
8178 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8179 All PCI entries are updated. Now LFSR is supported.
8180 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8181 * added pic16_newpCodeOpLit2 to support instructions with
8182 two literal arguments
8183 * pic16_pCode2str: corrected code that emits assembler instructions
8184 with two literal operands and those that have an access bit modifier
8185 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8186 this fixes a bug which caused some labels to be lost, when an
8187 assembler directive was added, i.e. banksel,
8188 * pic16_FixRegisterBanking: improved logic that causes the insertion
8190 * InlineFunction: functions that are called once, are not any more
8191 inlined. This can be a port option in the future,
8193 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8195 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8196 hold the corresponding uninitialized symbols,
8197 * pic16_allocProcessorRegister: registers have explicit marked the
8199 * pic16_allocInternalRegister: registers are explicit marked as
8201 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8202 processing list, so bit registers were lost,
8205 * ralloc.h: added field 'accessBank' and original symbol operand
8206 in register definition,
8207 * removed the field isMapped from register definition,
8209 ** Several functions have been removed from various sources:
8210 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8211 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8212 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8213 pic16_assignRelocatableRegisters
8215 ** others have been introduced:
8216 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8217 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8219 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8221 * support/scripts/inc2h.pl: changed definition of BIT_AT
8222 to emit 'sbit at' instead of 'bit at'. This was a request.
8224 PIC16 port related preliminary changes:
8225 * gen.c: prefixed function popRegFromString with
8226 pic16_ and all references to it corrected
8227 * pcode.c: all pic16_pc_* hardware registers prefixed
8228 with underscore (_),
8229 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8230 * ralloc.c: newReg(): when register is REG_SFR then
8231 set address to rIdx,
8232 pic16_allocProcessorRegister(): marks register wasUsed=0
8233 pic16_writeUsedRegs(): added a call to assign processor
8234 registers via pic16_assignFixedRegisters
8236 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8238 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8239 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8240 variables in unused register banks. Also the SSEG is placed
8241 wherever there is enough space for it, and IDATA can be anywhere
8242 in internal RAM. For now compile using -Wl-Y[stack_size].
8243 The mem file is different for this option as well, since it
8244 makes no sense of talking about DSEG lenght.
8246 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8248 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8249 in certain cases, e.g. when ROM assignment, patch provided
8250 from Albert den Haan.
8252 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9259 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9260 If they pop r0/r1 they must be called in the opposite order than aopOp().
9261 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9262 (resp. --stack-auto), prepared for --xstack

9273 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9275 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9276 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9277 type for bits was changed. It resulted in bit variables becoming

9293 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9295 A few small changes that speed up the peephole optimizer.
9299 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9301 Try to make the peephole optimizer smarter by maintaining
9302 an association between the assembly source code and the
9303 iCodes that originated them. Put this information to use
9304 with a new peephole rule condition "notVolatile" so that
9305 the rules can be aggressive yet still safe.
9310 * src/mcs51/peeph.def
9312 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9316 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9317 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9318 if the left or right operand symbols have the accuse flag set.
9320 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9322 Changed the type of the result of the ! (NOT) operator to char;
9323 previously it returned the same type as the source. This allows
9324 us to eliminate all the genFloatNot functions (all of its target
9325 implementations were very buggy) since !float can use the same
9328 * src/SDCCicode.c (ast2iCode): ! returns char
9329 * src/mcs51/gen.c (genNot, genNotFloat),
9330 * src/ds390/gen.c (genNot, genNotFloat),
9331 * src/z80/gen.c (genNot, genNotFloat),
9332 * src/pic/gen.c (genNot, genNotFloat),

9337 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9338 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9339 during interrupts. Ensure WSAVE is located at a shared bank address.
9340 2. Fixed page selection in some places
9341 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9342 the registers name strings.
9343 4. Fixed "signed / unsigned compare" compiler warnings.
9344 5. The PIC port manages its own allocation of the general purpose
9345 registers, but makes no attempt to reuse them. As a result when
9346 compiling it soon runs out of general purpose registers. Some
9347 additional code was added to the files pcode.c and device.c to walk
9348 through the function call tree and rename the registers so that they
9358 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9359 genPlus() & genMinus() when the result is the same as left or right

9365 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9367 Made bitfield a distinct type from bit so that bitfields
9368 convert as per ANSI C and bits retain their traditional
9369 boolean style behaviour. Implemented bitfield support in
9377 * src/ds390/gen.c: bit v bitfield split
9378 * src/z80/gen.c: New support for bitfields
9379 * support/regression/tests/bitfields.c: reenabled z80,
9382 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9384 Rules 246.x, 247.x relate to bitfields, the others speed up
9385 access to xdata mapped I/O devices.
9387 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9389 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9391 Cleaned up genPackBits and genUnpackBits and added two helper
9392 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9393 for literal assignments in genPackBits (thanks to Frieder for
9399 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9401 Fixed bug #748310 (pointer to function type mishandled when the
9402 function name is omitted). Also fixed a SIGSEGV when a function
9403 attribute (reentrant, etc) is used on a non-function or on a
9404 function but misplaced before the parameter list.

9431 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9433 Made the constant following the "interrupt" keyword optional. If
9434 omitted, the function will not automatically be given an entry
9435 in the interrupt vector table (similar to #pragma NOIV, but
9436 less syntacticly kludgy). The interrupt number is also now
9437 range checked. Also fixed a bug in the high order bit example

9966 * src/SDCCmain.c: linkOptions is changed to set *,
9967 added if/endif conditional macros to remove options help
9968 messages from optionsTable when a port is not configured, added
9969 support for the PIc16 port in the ports table, when executing
9970 the compiler with no port specified on command line, a default
9971 port is selected with the new macro DEFAULT_PORT which is
9972 defined in port.h, in setDefaultOptions() linkOptions is removed
9973 from initialization assignment, since now it is a set,
9974 parseCmdLine uses setParseWithComma for linkOptions, in
9975 linkEdit() linkOptions are accessed with new function indexSet()
9976 which returns the i'th item of a set variable. See SDCCset.c, in
9977 linkEdit() when calling buildCmdLine(), added linkOptions as
9978 last argument. Now users can pass arguments to gplink via the
9979 -Wl option, main() uses pic16glue() to glue up pic16 programs

9991 * src/pic16/glue.c: commented out some error producing lines
9992 * src/pic16/main.c: __config directives are commented out to stop
9993 gpasm complaining and test the linkage with gplink, _linkCmd and
9994 _asmCmd changed to be more gplink and gpasm friendly
9995 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9996 produced an error when parsed, peep rule 12 is added to utilize
9997 movff, but it is commented out since the pCode does not support
9998 yet a command with 2 address arguments

11063 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11065 * in /sdcc/as/mcs51/ changed these files in order to create an
11066 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11067 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11068 following files to include the previous two files: aslink.dsp,
11069 Makefile.aslink, Makefile.bcc, and Makefile.in.
11071 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11072 .adb instead of .cdb
11074 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11076 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11077 value from option --iram-size.
11079 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11081 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11084 2002-09-18 <wiml AT hhhh.org>
11086 * SDCClrange.h: exposed setFromRange() and setToRange()
11087 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11088 packRegsForAccUse() (bug 542397)
11089 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11090 multiple times and emitting the fetch operations more than once
11091 added aopGetUsesAcc() function to allow binary operators to
11092 fetch their operands in the correct order; made genMinus() emit
11093 compact code for X = LITERAL - Y
11095 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11096 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11097 sprintf() in line 1267.
11099 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11100 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11103 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11104 Changes to aslink (All the changes are marked with 'JCF'):
11106 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11109 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11110 area BSEG. Also moves, if possible, the DATA area down into the internal
11111 ram so more space is available.
11113 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11116 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11117 not bytes. Function summary() which creates a memory usage summary
11118 file with extension .mem. Reports of overlaping stack and small stack
11119 size. If the space for the stack is less than 16 bytes aslink trows a
11122 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11123 the 8051. Option 'y' for memory summary output file.
11125 Changes to sdcc (All the changes are marked with 'JCF'):
11127 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11129 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11130 overlaying area for it (uses RegBankUsed[4]).
11132 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11133 bank zero as used by default. By default aslink locates the stack
11134 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11135 the creation of the .mem file. Delegates the allocation of data area
11136 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11137 the begining of the stack area to aslink.
11139 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11140 glue() in SDCCglue.c creates an area for it.
11142 2002-09-03 Borut Razem <borut.razem AT siol.net>
11143 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11144 sdcc/src/pic/glue.c:
11145 introduced atexit() handler for teporay files removal in case of
11146 errors, assertions, ...
11148 2002-08-29 Borut Razem <borut.razem AT siol.net>
11149 * sdcc/support/cpp2/auto-host_vc_in.h:
11150 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11151 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11152 Maybe there is a similar problem with BORLANDC? It should be checked!
11154 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11155 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11156 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11157 was not executed, and the compiler (cl) launched a warning:
11158 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11160 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11161 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

11175 - VC .exe files are generated in bin_vc directory, not to interfere
11176 with binaries generated from other projects (cygwin, mingw, bcc ...)
11178 * sdcc/src/yacc.dsp: added
11180 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11181 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11182 and insert the version number definitions from .version
11184 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11186 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

11193 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11195 2002-08-11 Borut Razem <borut.razem AT siol.net>
11196 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11198 2002-08-10 Borut Razem <borut.razem AT siol.net>
11199 * src/SDCCmain.c (main):
11200 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11201 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11202 The consequence was that some temporary files were not removed.
11205 unification of code in functions tempfilename() and tempfile():
11206 function tempnam() is defined in Visual Studio 6.0 and .NET
11208 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11210 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11211 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11212 - removed compiler command line option /WX: Treats all warnings as errors
11213 - update a list of source files, included into the project
11215 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11216 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11217 changed project type to Generic Project so that can be correcly converted to VS.NET project
11219 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11221 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11223 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11225 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11226 added return 0 statements after assert() to make compiler happy
11228 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11229 added newline in the def file to keep MSC compiler satisfied
11231 * sdcc/src/z80/gen.c:
11232 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11233 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11234 - solved MSC error in function aopDump()
11236 * sdcc_vc.h: define PREFIX as "\\sdcc"
11238 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11239 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11411 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11413 * sdcc/src/SDCCloop.c:
11414 Previous fix was not good. basic blocks that have "break" or "return" are
11415 not really partof a loop , but live ranges used in these blocks should
11416 be live thru the entire loop, so set partOfLoop but don't add them to
