1191 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1193 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1194 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1196 One basic decision: e.g. src/clean.mk includes further files. In order
1197 to make this work there are two solutions:
1198 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1199 run configure on them. This way they can use
1200 'include $(srcdir)/port-clean.mk'
1201 - always include clean.mk by the Makefile at the same level. To avoid
1202 that `make clean` tries to include and build Makefile.dep the
1203 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1204 implemented, because now even `make uninstall` doesn't create
1205 Makefile.in. clean.mk could be eliminated by pasting it in
1208 * debugger/mcs51/Makefile.in: build own objects from library sources
1209 (SLIB, SDCC) in current directory
1211 * configure, configure.in: renamed --disable-device-lib-build in
1212 --disable-device-lib; added --enable-doc, the required tools are
1213 searched by configure; added result message; the toolchain for the
1214 belonging ports are now only built, if the port is enabled.
1216 * support/regression/*: all output is written in directory gen, because
1217 the fwk and ports directories don't livet in the build tree using vpath
1219 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1220 --disable-device-lib, added --enable-doc, added section VPATH
1222 * sim/ucsim/configure.in,
1223 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1224 z80 are enabled by default
1226 2006-04-24 Raphael Neider <rneider AT web.de>
1228 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1229 to config word, "pic14_"-prefixed some extern functions
1230 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1231 config word has been found
1232 * src/pic/device.h: added prototypes
1233 * src/pic/pcode.c: added "pic14_"-prefix where needed
1234 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1236 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1239 (pic14createInterruptVect): moved generating __config directives away

1249 registers that have not been assigned proper liveranges,
1250 fixes #1469504 and #1474602,
1251 (pCodeRegOptimizeRegUsage): fixed typo in comment
1253 2006-04-24 Borut Razem <borut.razem AT siol.net>
1255 * device/examples/main8051.c: deleted - it was removed from CVS

1257 after the transition to Subversion

1497 implemented patch 1120823 Thanks to Willy De la Court (normal
1498 interrupts need an interrupt number now if they are made critical),
1499 and enabled nesting of critical functions though not for gbz80
1500 (genCritical, genEndCritical): added functions
1501 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1502 * src/z80/mappings.i: added "ei" to all mappings

1514 the left operand is shorter than the result (c* = lit-c* + int),
1516 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1519 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1521 * src/.version: increased version number to 2.5.5
1522 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1523 linking is done manually in pic16 port's _linkEdit,
1524 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1525 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1526 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1527 allocate asmop as AOP_ACC,
1528 (aopForRemat): added parameter 'bool result' in function declaration,
1529 (pic16_aopGet): return AOP_ACC when accessing WREG,
1530 (pic16_popGetTempReg): minor modification,

1541 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1542 call to allocReg, not by manually allocating a new one,
1543 (pic16_assignRegisters): now before going through the register
1544 allocating functions mark all registers as free. This eliminates some
1545 side effects resulting from peephole parser done earlier in the backbone
1547 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1605 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1606 which dumps before the function entry point a data byte which represents
1607 the number of the local variables used by the specified function, added
1608 'xinst' for initial support for Extended Instruction Support,
1609 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1610 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1611 port->fun_prefix anymore (may change later),
1612 (genFunction, genEndFunction): do not store/restore local registers for
1613 _main (this should take care the --main-return command line option in
1615 (genOr): removed some legacy pic-port instructions,
1616 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1617 performing operations with SFR's causes data to be written more than
1618 once to each SFR. Perhaps SFRs should be handled in special cases...
1619 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1621 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1622 into account for stack starting position,

1624 --extended or -y for Extended Instruction Support,
1625 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1626 (deassignLRs): *** perhaps the most important change, old 'for' code
1627 (commented out for reference), didn't account for some registers which
1628 were left marked 'not free' after a pointer operation. The change
1629 reduces register usage a lot in some cases
1631 2006-03-04 Borut Razem <borut.razem AT siol.net>

3898 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3900 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

3902 * src/SDCCglobal.h (struct options),
3904 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3905 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3906 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3907 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3908 always available in leading double underscore form. The C99 support is
3909 mostly missing, but it's a start.
3910 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3911 reserved identifier "__data".
3913 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3959 2005-03-20 Borut Razem <borut.razem AT siol.net>
3961 * support/scripts/inc2h.pl: WIN32 port

3989 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3991 * device/lib/printf_large.c: removed inline assembly for portability and
3992 readability. Use printf_fast if speed or size are more important.
3993 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3994 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3996 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3998 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3999 prevent compiler warning
4001 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4003 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4004 moved to level 0 and declared as static. Also they are explicit
4005 placed in access bank. This was necessery because some times they
4006 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4007 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4008 optimizations. Currently only compare to unsigned char is implemented,
4009 * src/pic16/gen.c: added fReturnIdx array,
4010 * (struct resolvedIfx) is moved to gen.h and made public,
4011 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4012 * (aopForSym): added an optimization to directly store in stack of
4013 the operand of a SEND iCode,
4014 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4015 but as registers instead (AOP_REG) using the fReturnIdx array,
4016 * (pic16_freeAsmop): remove the freed register from the
4017 _G.sregsAlloc field,
4018 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4019 a compare of 'WREG',
4020 * (pic16_popGetTempRegCond): changed function prototype, now
4021 function takes also a bitVector argument v which holds the current
4022 set of registers that are allocated for stack access by aopForSym,
4023 registers allocated in aopForSym for accessing stack symbols are not
4024 any more part of the functions usedRegs field,
4025 * (genCall): some times aopOp is called for a stack variable to be
4026 send, aopForSym might perform the push, if this is true make sure
4027 that genCall doesn't push the variable twice by testing _G.resDirect,
4028 * (genFunction): changed testing for unspecified interrupt number
4029 from 256 to INTNO_UNSPEC,
4030 * modified selection scheme of frame pointer generation. Previously
4031 if function did use local registers a frame pointer was generated,
4032 now a frame pointer is generated only if function has arguments
4033 (that need PLUSW2 register access), or has stack arguments, or the
4034 compiler is not instructed to omit the frame pointer,
4035 * (genEndFunction): before restoring local registers that were saved
4036 in the function preamble, also restore the registers that *might*
4037 have been allocated for stack access,
4038 * (genRet): removed some old comments,
4039 * (genCmp, the active (RN's) version): added a call to the
4040 pic16_genCmp_special function to perform the compare with a more
4041 robust and optimized way,
4042 * (genInline): a feature has been added in inline code generation,
4043 which allows a wildcard variable substitution when writing inline
4044 assembly. Code is incomplete and experimental therefore undocumented,
4045 * (genCast): changed order of aopOp for result and right to allow
4046 aopForSym to directly load the result if possible,
4047 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4048 perform an optimized compare on some selected special occasions,
4049 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4050 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4051 generate an IVT any more,
4052 * src/pic16/main.c (pic16_optionsTable): added command line option
4054 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4055 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4057 * src/pic16/NOTES: Raphael Neider added in list of active developers
4058 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4059 jumptable_end to prevent bug #,
4060 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4061 inCond and outCond fields,
4062 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4063 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4064 turn off register spilling,
4065 * (packRegsForOneUse): synced with other ports' versions although it
4066 is not used currently,
4067 * (pic16_packRegisters): added an optimization while reading
4068 structure bitfields, some registers may be saved (malloc code is
4069 decreased by 80 bytes)
4071 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4073 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4074 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4075 this can be optimized more?
4077 2005-03-10 Raphael Neider <rneider AT web.de>
4079 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4080 genNearPointerGet): (hopefully) fixed access to bitfields via
4081 pointers (p->bitN = x; and x = p->bitN; failed)
4083 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4260 * src/pic16/main.c (_process_pragma): fixed another malloc bug
4261 (sizeof(sectNames) changed to sizeof(sectName))
4262 Both patches fix segfaults under MinGW.

4269 of (byte sized) temporaries (assign them to WREG for now)
4270 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4271 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4272 this might fix SIGSEGVs on MinGW...
4273 * src/SDCCopt.c (killDeadCode): restored original behaviour
4274 (volatile operands might get thrown away though)
4276 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>
4278 * src/pic16/gen.c: fixed bug #1106975,

4283 * added function attribute 'shadowregs' to take advantage of shadow
4285 * added function attribute 'wparam' as an alternative to the wparam
4287 * support/Utils/SDCCerr.[ch]: added error E_SHADOWREGS_NO_ISR when
4288 user declares a non-ISR function as 'shadowregs',
4289 * doc/sdccman.lyx: updated to reflect recent changes of pic16 port

4730 * support/regression/tests/bug1057979.c: added test for bug 1073386
4732 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
4734 * src/pic16/pcode.c: fixed bug which may produce error in non-GNU
4737 2004-11-25 Vangelis Rokas <vrokas AT otenet.gr>
4739 * src/pic16/device.h,
4740 * src/pic16/genarith.c,
4743 * src/pic16/pcode.c: applied patches #1068154 and #1070213
4745 2004-11-24 Vangelis Rokas <vrokas AT otenet.gr>
4747 Large cummulative patch for pic16 port.
4748 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4749 to call when a stack overflow occurs,
4750 * (malloc.h): added CVS Id tag,
4751 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4753 * added libc directory. The current version of LibC contains string
4754 functions, ctype functions and macros and some functions of the
4755 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4756 be extensively tested in the future. Standard disclaimer here.
4757 Library is not automatically build yet. But one can build it by
4758 invoking 'make' inside the libc directory.
4759 * added ADC library under libio. Preliminary version yet.
4761 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,
4762 * src/pic16/gen.c (aopForRemat): asmop size is filled by
4763 aopForRemat() now and not by pic16_aopOp(),
4764 * (pic16_popGetTempReg): removed warning messgae when allocating
4765 temporary registers, its a buggy feature and will be removed,
4766 * (pic16_popGet): set register instance field in AOP_CRY,
4767 * (pic16_outBitC): fixed for results in size greater than 1,
4768 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4769 * (pic16_storeForReturn): optimized return of 0,
4770 * (genCmp): experimental code for new genCmp which uses PIC18's
4771 special compare&skip instructions. Initial tests fail some times
4772 with variables grater than 1 byte in size, so new code is disabled,
4773 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4775 * (genCast): began a fix to optimize the casting of a bit to another
4776 bit, now assigning a bitfield to another bitfield will fail, sorry,
4777 * src/pic16/main.c: disabled the use of lr-support feature,
4778 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4779 * added some function prototypes, added function _debugf prototype,
4780 * src/pic16/pcode.c: (pic16_get_op): fixed emitting operands of register
4781 bits with offset (case PO_GPR_BIT),
4782 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4784 * (isBankInstruction): modified to return 0 for no banking instruction,
4785 and 1 for banking instruction,
4786 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4787 caused stop processing pCodes after a inline assembly block,
4788 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4789 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4790 registers when it shouldn't,
4791 * src/pic16/ralloc.c (allocReg): add preliminary support for
4792 supporting a limited set of temporary registers,
4794 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4796 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4797 genDataPointerSet): ensure assignments always copy in MSB to LSB
4799 (loadRegFromAop): recognize CLRH optimization,
4800 (genFunction): optimize RECEIVE iCodes in reentrant functions
4802 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4804 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4805 --out-fmt-s19 turning into --out-fmt-elf if s19 was already
4807 * src/SDCCmain.c (linkEdit): don't define SSEG for HC08

4814 * device/lib/_gptrgetc.c (_gptrgetc),
4815 * device/lib/_gptrput.c (_gptrput): _naked allows to use ret
4816 instead of sjmp to ret

4818 by Hubert Sack <hsack2002 AT arcor.de> in RFE #1067986, thanks

7799 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7801 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7802 loaded with the linker search paths (-L arguments) and the libraries
7803 to be linked with the current source (-l arguments). Changes
7804 currently will affect only the pic16 port.
7805 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7806 include path the port specific paths and port specific libraries,
7807 * gplink command now contains the $3 argument,
7808 * src/pic16/device.h,
7809 * src/pic16/device.c,: structure PIC_device is made public and
7810 renamed to PIC16_device, the same for variable Pics which is renamed

7825 Documenting changes from previous commits.
7826 * configure.in (version 1.56),
7827 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7828 when generating output files to configure the pic16 library,
7829 but now I've commented it out, since gputils aren't installed in the
7830 SF compile farm, so library won't compile
7832 * device/lib/Makefile.in (version 1.56): initially I've added in
7833 target 'all' the prerequestive 'model-pic16' so it compiled the
7834 pic16 library, but now I've commented it out for the same reasons
7836 * added targets 'model-pic16' and 'objects-pic16' to compile the
7838 * added target 'port-specific-objects-pic16' to handle the
7839 generated libraries and copy them into the build/ directory
7840 * added target 'clean-intermediate-pic16' to clean intermediate
7841 files into pic16 directory
7842 * in target 'installdirs' added line to create directory pic16 in

7863 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7864 option so that it actually works. Made it specific to the z80, since
7865 the gbz80 doesn't have these kinds of I/O ports.

7893 via literal number. The symbol is placed in the corresponding
7894 position of the data ram
7895 * (pic16_dump_section): relocatable and absolute uninitialized
7896 data are now emitted in sorted order to reduce section naming,
7897 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7898 weren't marked as being in the access bank,
7900 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7902 Added portion of GNU PIC Library under the directory
7903 device/include/pic16 and device/lib/pic16. These files
7904 contain the declarations of SFRs for the PIC18Fxx2 devices.
7905 The directory is initialized via configure from toplevel.
7907 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7909 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

7935 all over. Telling LaTeX to be less strict with word spacing
7936 to better keep the right margin. Changed some notes about
7937 maintainance of the ports in section 3.2.1 - is it OK like this?
7939 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7977 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7979 * src/pic16/peeph.def: all peepholes with movff are commented out,
7980 because there is a problem in the pcode peep optimizer,
7981 * src/pic16/ralloc.c: the register allocator can now reuse local
7982 function symbols for another function. This saves register usage.
7983 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7985 Added file src/pic16/NOTES with information about program writing on
7986 the current port version.

8015 gen51Code): more efficient parameter receive for --model-large
8018 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8021 * src/z80/main.c: added missed needLinkerScript flags (more than
8022 one port structure defined in these file)
8023 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

8039 needLinkerScript flag
8041 * src/pic16/gen.c (genAddrOf): fixed bug #863624
8042 * src/pic/glue.c: added variable udata_section_name to
8043 override default uninitialized data segment definition for
8044 devices only with SHAREBANK memory (reported from Erik Epetrich)
8045 * (pic14emitOverlay): modified to emit a commented overlay segment
8046 directive when no overlay data exist
8047 * (picglue): modified to emit uninitialized data segment
8048 according to udata_section_name

8058 2004-01-07 Borut Razem <borut.razem AT siol.net>
8060 * support/scripts/sdcc.nsi: update PATH
8061 * support/scripts/sdcc.ico: craeted

8074 include information about variables allocated to the overlay
8077 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8079 * as/mcs51/lkmain.c: Help about -Y option

8091 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8093 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8094 (default behaviour).
8096 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8098 A python script to validate compiler diagnostic messages. It can be
8099 used to verify that sdcc complains about bad c source code and
8100 gives a good location of the error.
8101 * support/valdiag/Makefile,
8102 * support/valdiag/valdiag.py,
8103 * support/valdiag/tests/*
8105 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8107 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

8118 * src/common.h: added ifndef/define/endif macros
8119 around the header file.
8120 Bug reported from Jesus Calvino-Fraga
8122 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8124 * sdcc.spec: updated
8125 * device/include/Makefile.in: don't install CVS directories
8126 * device/lib/Makefile.in: added removal of CVS directories after install
8127 * doc/Makefile: fixed install, added local_icons
8128 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8129 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8130 * src/ds390/gen.c (genRightShift): fixed bug #870788
8131 * src/SDCCast.c (decorateType): fixed bug #870781
8133 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8135 PIC16 port related changes:
8136 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8137 added variable stackPos,
8139 * gen.c: genCall, assignResultValue: added support for
8140 pushing/retrieving function parameters to/from stack,
8141 genFunction,genEndFunction: setup stack frame for the
8143 genAddrOf: will be changed according to bug 863624
8145 * added files genutils.c and genutils.h which contain gen*
8146 debugged and optimised functions extracted from gen.c
8148 * glue.c: added variable 'externs' which holds extern symbols,
8149 pic16emitRegularMap: is modified to properly handle relocatable
8150 symbols under the new scheme,
8151 pic16createInterruptVect: is modified
8152 pic16printPublics: is modified to emit 'global' assembler directives,
8153 added pic16_printExterns to print extern symbols,
8154 pic16glue: initializes stack/frame pointer in the beginning of
8155 the assembly output. Temporary hack, will be corrected later,
8156 because gplink yet does not support stack and SDCC does not
8157 yet support a type of crt0.o object to create the final binary.
8159 * Removed many lines that contain 8051 legacy code.
8160 * The code is finally placed under a 'code' directive.
8161 * Added port specific options.
8163 * _process_pragma: simplified since now we do not need *special*
8164 include file to define SFR registers. But a separate header
8165 will be needed. This will be developed later.
8166 * _pic16_parseOptions: added, parses port specific options:
8167 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8168 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8169 --preplace-udata-with=
8171 * _pic16_setDefaultOptions: modified to initialize section names,
8172 but hack is temporarly out of order since it needs improvement.
8173 * _pic16_genAssemblerPreamble: configuration words are emitted by
8174 their address instead of their name. This part is incomplete and
8175 supports only the 18Fxx2 devices. Other devices will emit an error
8176 during assembly since they do not contain the same set of config
8178 * _pic16_genIVT: is modified,
8180 * pcode.c: added definitions for some hardware registers that are needed
8182 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8183 All PCI entries are updated. Now LFSR is supported.
8184 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8185 * added pic16_newpCodeOpLit2 to support instructions with
8186 two literal arguments
8187 * pic16_pCode2str: corrected code that emits assembler instructions
8188 with two literal operands and those that have an access bit modifier
8189 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8190 this fixes a bug which caused some labels to be lost, when an
8191 assembler directive was added, i.e. banksel,
8192 * pic16_FixRegisterBanking: improved logic that causes the insertion
8194 * InlineFunction: functions that are called once, are not any more
8195 inlined. This can be a port option in the future,
8197 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8199 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8200 hold the corresponding uninitialized symbols,
8201 * pic16_allocProcessorRegister: registers have explicit marked the
8203 * pic16_allocInternalRegister: registers are explicit marked as
8205 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8206 processing list, so bit registers were lost,
8209 * ralloc.h: added field 'accessBank' and original symbol operand
8210 in register definition,
8211 * removed the field isMapped from register definition,
8213 ** Several functions have been removed from various sources:
8214 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8215 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8216 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8217 pic16_assignRelocatableRegisters
8219 ** others have been introduced:
8220 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8221 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8223 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8225 * support/scripts/inc2h.pl: changed definition of BIT_AT
8226 to emit 'sbit at' instead of 'bit at'. This was a request.
8228 PIC16 port related preliminary changes:
8229 * gen.c: prefixed function popRegFromString with
8230 pic16_ and all references to it corrected
8231 * pcode.c: all pic16_pc_* hardware registers prefixed
8232 with underscore (_),
8233 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8234 * ralloc.c: newReg(): when register is REG_SFR then
8235 set address to rIdx,
8236 pic16_allocProcessorRegister(): marks register wasUsed=0
8237 pic16_writeUsedRegs(): added a call to assign processor
8238 registers via pic16_assignFixedRegisters
8240 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8242 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8243 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8244 variables in unused register banks. Also the SSEG is placed
8245 wherever there is enough space for it, and IDATA can be anywhere
8246 in internal RAM. For now compile using -Wl-Y[stack_size].
8247 The mem file is different for this option as well, since it
8248 makes no sense of talking about DSEG lenght.
8250 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8252 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8253 in certain cases, e.g. when ROM assignment, patch provided
8254 from Albert den Haan.
8256 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8801 2003-10-30 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8803 Fixed a number of problems revealed by bug #827883.
8804 * src/SDCCloop.c (loopInvariants): Spill location of the
8805 result operand should be recomputed if extracted from
8806 a loop. Also, don't extract assignments of an iTemp
8808 * src/SDCCast.c (isConformingBody): loop reversal should
8809 not occur if the control variable is involved with a
8810 relational operator.

9297 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9299 A few small changes that speed up the peephole optimizer.
9303 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9305 Try to make the peephole optimizer smarter by maintaining
9306 an association between the assembly source code and the
9307 iCodes that originated them. Put this information to use
9308 with a new peephole rule condition "notVolatile" so that
9309 the rules can be aggressive yet still safe.
9314 * src/mcs51/peeph.def
9316 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9326 Changed the type of the result of the ! (NOT) operator to char;
9327 previously it returned the same type as the source. This allows
9328 us to eliminate all the genFloatNot functions (all of its target
9329 implementations were very buggy) since !float can use the same

9341 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9342 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9343 during interrupts. Ensure WSAVE is located at a shared bank address.
9344 2. Fixed page selection in some places
9345 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9346 the registers name strings.
9347 4. Fixed "signed / unsigned compare" compiler warnings.
9348 5. The PIC port manages its own allocation of the general purpose
9349 registers, but makes no attempt to reuse them. As a result when
9350 compiling it soon runs out of general purpose registers. Some
9351 additional code was added to the files pcode.c and device.c to walk
9352 through the function call tree and rename the registers so that they
9362 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

9369 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9371 Made bitfield a distinct type from bit so that bitfields
9372 convert as per ANSI C and bits retain their traditional
9373 boolean style behaviour. Implemented bitfield support in
9381 * src/ds390/gen.c: bit v bitfield split
9382 * src/z80/gen.c: New support for bitfields
9383 * support/regression/tests/bitfields.c: reenabled z80,
9386 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9388 Rules 246.x, 247.x relate to bitfields, the others speed up
9389 access to xdata mapped I/O devices.
9391 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9393 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9395 Cleaned up genPackBits and genUnpackBits and added two helper
9396 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9397 for literal assignments in genPackBits (thanks to Frieder for
9403 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9405 Fixed bug #748310 (pointer to function type mishandled when the
9406 function name is omitted). Also fixed a SIGSEGV when a function
9407 attribute (reentrant, etc) is used on a non-function or on a
9408 function but misplaced before the parameter list.

9435 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9437 Made the constant following the "interrupt" keyword optional. If
9438 omitted, the function will not automatically be given an entry
9439 in the interrupt vector table (similar to #pragma NOIV, but
9440 less syntacticly kludgy). The interrupt number is also now
9441 range checked. Also fixed a bug in the high order bit example

9917 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9918 the regression tests I'm not brave enough to enable 245.b, 245.c
9919 * doc/sdccman.lyx: added latex preamble for hyperref package.
9920 Using pdflatex this will give you a hyperlinked pdf file with

9970 * src/SDCCmain.c: linkOptions is changed to set *,
9971 added if/endif conditional macros to remove options help
9972 messages from optionsTable when a port is not configured, added
9973 support for the PIc16 port in the ports table, when executing
9974 the compiler with no port specified on command line, a default
9975 port is selected with the new macro DEFAULT_PORT which is
9976 defined in port.h, in setDefaultOptions() linkOptions is removed
9977 from initialization assignment, since now it is a set,
9978 parseCmdLine uses setParseWithComma for linkOptions, in
9979 linkEdit() linkOptions are accessed with new function indexSet()
9980 which returns the i'th item of a set variable. See SDCCset.c, in
9981 linkEdit() when calling buildCmdLine(), added linkOptions as
9982 last argument. Now users can pass arguments to gplink via the
9983 -Wl option, main() uses pic16glue() to glue up pic16 programs

9995 * src/pic16/glue.c: commented out some error producing lines
9996 * src/pic16/main.c: __config directives are commented out to stop
9997 gpasm complaining and test the linkage with gplink, _linkCmd and
9998 _asmCmd changed to be more gplink and gpasm friendly
9999 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10000 produced an error when parsed, peep rule 12 is added to utilize
10001 movff, but it is commented out since the pCode does not support
10002 yet a command with 2 address arguments
10004 2003-05-18 <johan AT balder>
10006 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10033 2003-05-11 Borut Razem <borut.razem AT siol.net>
10035 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
10036 the path of bin directory, so that PATH is the only env. variable, which has to be set

11067 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11069 * in /sdcc/as/mcs51/ changed these files in order to create an
11070 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11071 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11072 following files to include the previous two files: aslink.dsp,
11073 Makefile.aslink, Makefile.bcc, and Makefile.in.
11075 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11076 .adb instead of .cdb
11078 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11080 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11081 value from option --iram-size.
11083 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11085 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11088 2002-09-18 <wiml AT hhhh.org>
11090 * SDCClrange.h: exposed setFromRange() and setToRange()
11091 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11092 packRegsForAccUse() (bug 542397)
11093 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11094 multiple times and emitting the fetch operations more than once
11095 added aopGetUsesAcc() function to allow binary operators to
11096 fetch their operands in the correct order; made genMinus() emit
11097 compact code for X = LITERAL - Y
11099 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11100 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11101 sprintf() in line 1267.
11103 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11104 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11107 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11108 Changes to aslink (All the changes are marked with 'JCF'):
11110 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11113 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11114 area BSEG. Also moves, if possible, the DATA area down into the internal
11115 ram so more space is available.
11117 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11120 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11121 not bytes. Function summary() which creates a memory usage summary
11122 file with extension .mem. Reports of overlaping stack and small stack
11123 size. If the space for the stack is less than 16 bytes aslink trows a
11126 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11127 the 8051. Option 'y' for memory summary output file.
11129 Changes to sdcc (All the changes are marked with 'JCF'):
11131 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11133 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11134 overlaying area for it (uses RegBankUsed[4]).
11136 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11137 bank zero as used by default. By default aslink locates the stack
11138 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11139 the creation of the .mem file. Delegates the allocation of data area
11140 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11141 the begining of the stack area to aslink.
11143 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11144 glue() in SDCCglue.c creates an area for it.
11146 2002-09-03 Borut Razem <borut.razem AT siol.net>
11147 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11148 sdcc/src/pic/glue.c:
11149 introduced atexit() handler for teporay files removal in case of
11150 errors, assertions, ...
11152 2002-08-29 Borut Razem <borut.razem AT siol.net>
11153 * sdcc/support/cpp2/auto-host_vc_in.h:
11154 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11155 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11156 Maybe there is a similar problem with BORLANDC? It should be checked!
11158 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11159 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11160 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11161 was not executed, and the compiler (cl) launched a warning:
11162 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11164 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11165 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11167 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

11175 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11176 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11177 - added Release configuration in VS projects
11178 - review of compiler an linker options
11179 - VC .exe files are generated in bin_vc directory, not to interfere
11180 with binaries generated from other projects (cygwin, mingw, bcc ...)
11182 * sdcc/src/yacc.dsp: added
11184 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11185 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11186 and insert the version number definitions from .version
11188 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11190 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11191 added - genarate auto-host.h using auto-host_vc_in.h as template
11194 removed from CVS, generated automatically
11196 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11197 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11199 2002-08-11 Borut Razem <borut.razem AT siol.net>
11200 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11202 2002-08-10 Borut Razem <borut.razem AT siol.net>
11203 * src/SDCCmain.c (main):
11204 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11205 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11206 The consequence was that some temporary files were not removed.
11209 unification of code in functions tempfilename() and tempfile():
11210 function tempnam() is defined in Visual Studio 6.0 and .NET
11212 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11214 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11215 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11216 - removed compiler command line option /WX: Treats all warnings as errors
11217 - update a list of source files, included into the project
11219 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11220 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11221 changed project type to Generic Project so that can be correcly converted to VS.NET project
11223 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11225 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11227 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11229 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11230 added return 0 statements after assert() to make compiler happy
11232 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11233 added newline in the def file to keep MSC compiler satisfied
11235 * sdcc/src/z80/gen.c:
11236 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11237 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11238 - solved MSC error in function aopDump()
11240 * sdcc_vc.h: define PREFIX as "\\sdcc"
11242 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11415 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11417 * sdcc/src/SDCCloop.c:
11418 Previous fix was not good. basic blocks that have "break" or "return" are
11419 not really partof a loop , but live ranges used in these blocks should
11420 be live thru the entire loop, so set partOfLoop but don't add them to
