1173 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1175 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1176 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1178 One basic decision: e.g. src/clean.mk includes further files. In order
1179 to make this work there are two solutions:
1180 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1181 run configure on them. This way they can use
1182 'include $(srcdir)/port-clean.mk'
1183 - always include clean.mk by the Makefile at the same level. To avoid
1184 that `make clean` tries to include and build Makefile.dep the
1185 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1186 implemented, because now even `make uninstall` doesn't create
1187 Makefile.in. clean.mk could be eliminated by pasting it in
1190 * debugger/mcs51/Makefile.in: build own objects from library sources
1191 (SLIB, SDCC) in current directory
1193 * configure, configure.in: renamed --disable-device-lib-build in
1194 --disable-device-lib; added --enable-doc, the required tools are
1195 searched by configure; added result message; the toolchain for the
1196 belonging ports are now only built, if the port is enabled.
1198 * support/regression/*: all output is written in directory gen, because
1199 the fwk and ports directories don't livet in the build tree using vpath
1201 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1202 --disable-device-lib, added --enable-doc, added section VPATH
1204 * sim/ucsim/configure.in,
1205 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1206 z80 are enabled by default
1208 2006-04-24 Raphael Neider <rneider AT web.de>
1210 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1211 to config word, "pic14_"-prefixed some extern functions
1212 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1213 config word has been found
1214 * src/pic/device.h: added prototypes
1215 * src/pic/pcode.c: added "pic14_"-prefix where needed
1216 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1218 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1221 (pic14createInterruptVect): moved generating __config directives away
1222 (picglue): have __config directives emitted

1233 (pCodeRegOptimizeRegUsage): fixed typo in comment

1479 implemented patch 1120823 Thanks to Willy De la Court (normal
1480 interrupts need an interrupt number now if they are made critical),
1481 and enabled nesting of critical functions though not for gbz80
1482 (genCritical, genEndCritical): added functions
1483 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1484 * src/z80/mappings.i: added "ei" to all mappings

1496 the left operand is shorter than the result (c* = lit-c* + int),
1498 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1501 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1503 * src/.version: increased version number to 2.5.5
1504 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1505 linking is done manually in pic16 port's _linkEdit,
1506 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1507 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1508 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1509 allocate asmop as AOP_ACC,
1510 (aopForRemat): added parameter 'bool result' in function declaration,
1511 (pic16_aopGet): return AOP_ACC when accessing WREG,
1512 (pic16_popGetTempReg): minor modification,

1523 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1524 call to allocReg, not by manually allocating a new one,
1525 (pic16_assignRegisters): now before going through the register
1526 allocating functions mark all registers as free. This eliminates some
1527 side effects resulting from peephole parser done earlier in the backbone
1529 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1587 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1588 which dumps before the function entry point a data byte which represents
1589 the number of the local variables used by the specified function, added
1590 'xinst' for initial support for Extended Instruction Support,
1591 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1592 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1593 port->fun_prefix anymore (may change later),
1594 (genFunction, genEndFunction): do not store/restore local registers for
1595 _main (this should take care the --main-return command line option in
1597 (genOr): removed some legacy pic-port instructions,
1598 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1599 performing operations with SFR's causes data to be written more than
1600 once to each SFR. Perhaps SFRs should be handled in special cases...
1601 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1603 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1604 into account for stack starting position,

1606 --extended or -y for Extended Instruction Support,
1607 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1608 (deassignLRs): *** perhaps the most important change, old 'for' code
1609 (commented out for reference), didn't account for some registers which
1610 were left marked 'not free' after a pointer operation. The change
1611 reduces register usage a lot in some cases
1613 2006-03-04 Borut Razem <borut.razem AT siol.net>

3858 * device/lib/pic16/libc/delay/: NEW, c sources for the delay functions,
3859 * device/lib/pic16/libc/utils/: minor modifications in the .S sources,
3860 * device/lib/pic16/startup/{crt0i.c, crt0iz.c}: redesign of the
3861 _do_cinit function, because the previous failed when local variables
3862 where not placed in the same memory bank,
3863 * device/lib/pic16/libsdcc/char/: various modifications to improve
3864 library performance,
3865 * doc/sdccman.lyx: some reorganization of the PIC16 part, added many
3866 information on the new functions of the c library and more...
3868 2005-03-28 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3876 * (genCmp): adapted to new genSkipc semantics
3877 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
3878 on rIfx (genCmp was broken)
3880 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3882 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3883 * src/z80/main.c (_keywords[]),
3884 * src/SDCCglobal.h (struct options),
3886 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3887 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3888 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3889 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3890 always available in leading double underscore form. The C99 support is
3891 mostly missing, but it's a start.
3892 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3893 reserved identifier "__data".
3895 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3897 * src/mcs51/peeph.def: fixed bug 1170013
3899 2005-03-22 Maarten Brock <sourceforge.brock AT dse.nl>

3939 immedDom() returning wrong block; probably fixes bug #1160833)
3941 2005-03-20 Borut Razem <borut.razem AT siol.net>
3943 * support/scripts/inc2h.pl: WIN32 port
3945 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3947 * device/lib/makefile.in: added abs.c and labs.c
3949 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3951 * device/include/stdint.h: added
3952 * device/lib/abs.c: added
3953 * device/lib/labs.c: added
3954 * device/include/stdlib.h: added abs() and labs() prototypes

3969 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3971 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3973 * device/lib/printf_large.c: removed inline assembly for portability and
3974 readability. Use printf_fast if speed or size are more important.
3975 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3976 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3978 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3980 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3981 prevent compiler warning
3983 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3985 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3986 moved to level 0 and declared as static. Also they are explicit
3987 placed in access bank. This was necessery because some times they
3988 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3989 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3990 optimizations. Currently only compare to unsigned char is implemented,
3991 * src/pic16/gen.c: added fReturnIdx array,
3992 * (struct resolvedIfx) is moved to gen.h and made public,
3993 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3994 * (aopForSym): added an optimization to directly store in stack of
3995 the operand of a SEND iCode,
3996 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3997 but as registers instead (AOP_REG) using the fReturnIdx array,
3998 * (pic16_freeAsmop): remove the freed register from the
3999 _G.sregsAlloc field,
4000 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4001 a compare of 'WREG',
4002 * (pic16_popGetTempRegCond): changed function prototype, now
4003 function takes also a bitVector argument v which holds the current
4004 set of registers that are allocated for stack access by aopForSym,
4005 registers allocated in aopForSym for accessing stack symbols are not
4006 any more part of the functions usedRegs field,
4007 * (genCall): some times aopOp is called for a stack variable to be
4008 send, aopForSym might perform the push, if this is true make sure
4009 that genCall doesn't push the variable twice by testing _G.resDirect,
4010 * (genFunction): changed testing for unspecified interrupt number
4011 from 256 to INTNO_UNSPEC,
4012 * modified selection scheme of frame pointer generation. Previously
4013 if function did use local registers a frame pointer was generated,
4014 now a frame pointer is generated only if function has arguments
4015 (that need PLUSW2 register access), or has stack arguments, or the
4016 compiler is not instructed to omit the frame pointer,
4017 * (genEndFunction): before restoring local registers that were saved
4018 in the function preamble, also restore the registers that *might*
4019 have been allocated for stack access,
4020 * (genRet): removed some old comments,
4021 * (genCmp, the active (RN's) version): added a call to the
4022 pic16_genCmp_special function to perform the compare with a more
4023 robust and optimized way,
4024 * (genInline): a feature has been added in inline code generation,
4025 which allows a wildcard variable substitution when writing inline
4026 assembly. Code is incomplete and experimental therefore undocumented,
4027 * (genCast): changed order of aopOp for result and right to allow
4028 aopForSym to directly load the result if possible,
4029 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4030 perform an optimized compare on some selected special occasions,
4031 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4032 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4033 generate an IVT any more,
4034 * src/pic16/main.c (pic16_optionsTable): added command line option
4036 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4037 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4039 * src/pic16/NOTES: Raphael Neider added in list of active developers
4040 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4041 jumptable_end to prevent bug #,
4042 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4043 inCond and outCond fields,
4044 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4045 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4046 turn off register spilling,
4047 * (packRegsForOneUse): synced with other ports' versions although it
4048 is not used currently,
4049 * (pic16_packRegisters): added an optimization while reading
4050 structure bitfields, some registers may be saved (malloc code is
4051 decreased by 80 bytes)
4053 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4055 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4056 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4057 this can be optimized more?
4059 2005-03-10 Raphael Neider <rneider AT web.de>
4061 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4062 genNearPointerGet): (hopefully) fixed access to bitfields via
4063 pointers (p->bitN = x; and x = p->bitN; failed)
4065 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4252 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4253 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4254 this might fix SIGSEGVs on MinGW...
4255 * src/SDCCopt.c (killDeadCode): restored original behaviour
4256 (volatile operands might get thrown away though)
4258 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

4284 enable global optimizations for entire library source, other
4285 Makefiles in the source tree are also modified to reflect this,
4286 * device/lib/pic16/libc/stdlib/putchar.c (putchar): dummy putchar()
4288 * doc/sdccman.lyx: updated to reflect new changes,

4295 --pleave-reset-vector,
4296 * (pic16_finaliseOptions): when define macro SDCC_MODEL_{SMALL/LARGE}
4297 when calling assembler to reflect memory model used, also define
4298 macro STACK_MODEL_{SMALL/LARGE} when compiling and assembling to
4299 reflect stack model used,
4300 * src/pic16/ralloc.c (pic16_allocDirReg): when operand is allocated
4301 on stack return NULL,

4738 be extensively tested in the future. Standard disclaimer here.
4739 Library is not automatically build yet. But one can build it by
4740 invoking 'make' inside the libc directory.

4755 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4757 * (genCast): began a fix to optimize the casting of a bit to another
4758 bit, now assigning a bitfield to another bitfield will fail, sorry,

7781 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7783 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7784 loaded with the linker search paths (-L arguments) and the libraries
7785 to be linked with the current source (-l arguments). Changes
7786 currently will affect only the pic16 port.
7787 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7788 include path the port specific paths and port specific libraries,
7789 * gplink command now contains the $3 argument,
7790 * src/pic16/device.h,
7791 * src/pic16/device.c,: structure PIC_device is made public and
7792 renamed to PIC16_device, the same for variable Pics which is renamed

7807 Documenting changes from previous commits.
7808 * configure.in (version 1.56),
7809 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7810 when generating output files to configure the pic16 library,
7811 but now I've commented it out, since gputils aren't installed in the
7812 SF compile farm, so library won't compile
7814 * device/lib/Makefile.in (version 1.56): initially I've added in
7815 target 'all' the prerequestive 'model-pic16' so it compiled the
7816 pic16 library, but now I've commented it out for the same reasons
7818 * added targets 'model-pic16' and 'objects-pic16' to compile the
7820 * added target 'port-specific-objects-pic16' to handle the
7821 generated libraries and copy them into the build/ directory
7822 * added target 'clean-intermediate-pic16' to clean intermediate
7823 files into pic16 directory
7824 * in target 'installdirs' added line to create directory pic16 in
7825 the installation path
7827 * device/include/Makefile.in (version 1.11): in target 'install'
7828 added lines to copy all header files to installation path,
7829 * in target 'installdirs' added line create directory for pic16
7830 headers in the installation path

7845 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7846 option so that it actually works. Made it specific to the z80, since
7847 the gbz80 doesn't have these kinds of I/O ports.
7849 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7851 * device/include/z180.h,

7875 via literal number. The symbol is placed in the corresponding
7876 position of the data ram
7877 * (pic16_dump_section): relocatable and absolute uninitialized
7878 data are now emitted in sorted order to reduce section naming,
7879 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7880 weren't marked as being in the access bank,
7882 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7884 Added portion of GNU PIC Library under the directory
7885 device/include/pic16 and device/lib/pic16. These files
7886 contain the declarations of SFRs for the PIC18Fxx2 devices.
7887 The directory is initialized via configure from toplevel.
7889 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7891 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

7917 all over. Telling LaTeX to be less strict with word spacing
7918 to better keep the right margin. Changed some notes about
7919 maintainance of the ports in section 3.2.1 - is it OK like this?
7921 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7959 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7961 * src/pic16/peeph.def: all peepholes with movff are commented out,
7962 because there is a problem in the pcode peep optimizer,
7963 * src/pic16/ralloc.c: the register allocator can now reuse local

7965 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7967 Added file src/pic16/NOTES with information about program writing on
7968 the current port version.

8000 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8003 * src/z80/main.c: added missed needLinkerScript flags (more than
8004 one port structure defined in these file)
8005 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

8027 * (pic14emitOverlay): modified to emit a commented overlay segment
8028 directive when no overlay data exist
8029 * (picglue): modified to emit uninitialized data segment
8030 according to udata_section_name

8040 2004-01-07 Borut Razem <borut.razem AT siol.net>
8042 * support/scripts/sdcc.nsi: update PATH
8043 * support/scripts/sdcc.ico: craeted

8050 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8052 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
8054 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

8056 include information about variables allocated to the overlay
8059 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8061 * as/mcs51/lkmain.c: Help about -Y option

8073 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8075 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8076 (default behaviour).
8078 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8080 A python script to validate compiler diagnostic messages. It can be
8081 used to verify that sdcc complains about bad c source code and
8082 gives a good location of the error.
8083 * support/valdiag/Makefile,
8084 * support/valdiag/valdiag.py,
8085 * support/valdiag/tests/*
8087 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8089 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

8100 * src/common.h: added ifndef/define/endif macros
8101 around the header file.
8102 Bug reported from Jesus Calvino-Fraga
8104 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8106 * sdcc.spec: updated
8107 * device/include/Makefile.in: don't install CVS directories
8108 * device/lib/Makefile.in: added removal of CVS directories after install
8109 * doc/Makefile: fixed install, added local_icons
8110 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8111 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8112 * src/ds390/gen.c (genRightShift): fixed bug #870788
8113 * src/SDCCast.c (decorateType): fixed bug #870781
8115 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8117 PIC16 port related changes:
8118 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8119 added variable stackPos,
8121 * gen.c: genCall, assignResultValue: added support for
8122 pushing/retrieving function parameters to/from stack,
8123 genFunction,genEndFunction: setup stack frame for the
8125 genAddrOf: will be changed according to bug 863624
8127 * added files genutils.c and genutils.h which contain gen*
8128 debugged and optimised functions extracted from gen.c
8130 * glue.c: added variable 'externs' which holds extern symbols,
8131 pic16emitRegularMap: is modified to properly handle relocatable
8132 symbols under the new scheme,
8133 pic16createInterruptVect: is modified
8134 pic16printPublics: is modified to emit 'global' assembler directives,
8135 added pic16_printExterns to print extern symbols,
8136 pic16glue: initializes stack/frame pointer in the beginning of
8137 the assembly output. Temporary hack, will be corrected later,
8138 because gplink yet does not support stack and SDCC does not
8139 yet support a type of crt0.o object to create the final binary.
8141 * Removed many lines that contain 8051 legacy code.
8142 * The code is finally placed under a 'code' directive.
8143 * Added port specific options.
8145 * _process_pragma: simplified since now we do not need *special*
8146 include file to define SFR registers. But a separate header
8147 will be needed. This will be developed later.
8148 * _pic16_parseOptions: added, parses port specific options:
8149 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8150 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8151 --preplace-udata-with=
8153 * _pic16_setDefaultOptions: modified to initialize section names,
8154 but hack is temporarly out of order since it needs improvement.
8155 * _pic16_genAssemblerPreamble: configuration words are emitted by
8156 their address instead of their name. This part is incomplete and
8157 supports only the 18Fxx2 devices. Other devices will emit an error
8158 during assembly since they do not contain the same set of config
8160 * _pic16_genIVT: is modified,
8162 * pcode.c: added definitions for some hardware registers that are needed
8164 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8165 All PCI entries are updated. Now LFSR is supported.
8166 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8167 * added pic16_newpCodeOpLit2 to support instructions with
8168 two literal arguments
8169 * pic16_pCode2str: corrected code that emits assembler instructions
8170 with two literal operands and those that have an access bit modifier
8171 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8172 this fixes a bug which caused some labels to be lost, when an
8173 assembler directive was added, i.e. banksel,
8174 * pic16_FixRegisterBanking: improved logic that causes the insertion
8176 * InlineFunction: functions that are called once, are not any more
8177 inlined. This can be a port option in the future,
8179 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8181 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8182 hold the corresponding uninitialized symbols,
8183 * pic16_allocProcessorRegister: registers have explicit marked the
8185 * pic16_allocInternalRegister: registers are explicit marked as
8187 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8188 processing list, so bit registers were lost,
8191 * ralloc.h: added field 'accessBank' and original symbol operand
8192 in register definition,
8193 * removed the field isMapped from register definition,
8195 ** Several functions have been removed from various sources:
8196 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8197 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8198 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8199 pic16_assignRelocatableRegisters
8201 ** others have been introduced:
8202 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8203 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8205 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8207 * support/scripts/inc2h.pl: changed definition of BIT_AT
8208 to emit 'sbit at' instead of 'bit at'. This was a request.
8210 PIC16 port related preliminary changes:
8211 * gen.c: prefixed function popRegFromString with
8212 pic16_ and all references to it corrected
8213 * pcode.c: all pic16_pc_* hardware registers prefixed
8214 with underscore (_),
8215 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8216 * ralloc.c: newReg(): when register is REG_SFR then
8217 set address to rIdx,
8218 pic16_allocProcessorRegister(): marks register wasUsed=0
8219 pic16_writeUsedRegs(): added a call to assign processor
8220 registers via pic16_assignFixedRegisters
8222 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8224 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8225 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8226 variables in unused register banks. Also the SSEG is placed
8227 wherever there is enough space for it, and IDATA can be anywhere
8228 in internal RAM. For now compile using -Wl-Y[stack_size].
8229 The mem file is different for this option as well, since it
8230 makes no sense of talking about DSEG lenght.
8232 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8234 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8235 in certain cases, e.g. when ROM assignment, patch provided
8236 from Albert den Haan.
8238 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9245 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9246 If they pop r0/r1 they must be called in the opposite order than aopOp().

9261 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9262 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9263 type for bits was changed. It resulted in bit variables becoming

9281 A few small changes that speed up the peephole optimizer.
9285 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9287 Try to make the peephole optimizer smarter by maintaining
9288 an association between the assembly source code and the
9289 iCodes that originated them. Put this information to use
9290 with a new peephole rule condition "notVolatile" so that
9291 the rules can be aggressive yet still safe.
9296 * src/mcs51/peeph.def
9298 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9302 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9303 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9304 if the left or right operand symbols have the accuse flag set.
9306 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9308 Changed the type of the result of the ! (NOT) operator to char;
9309 previously it returned the same type as the source. This allows
9310 us to eliminate all the genFloatNot functions (all of its target
9311 implementations were very buggy) since !float can use the same
9314 * src/SDCCicode.c (ast2iCode): ! returns char

9316 * src/ds390/gen.c (genNot, genNotFloat),
9317 * src/z80/gen.c (genNot, genNotFloat),
9318 * src/pic/gen.c (genNot, genNotFloat),

9321 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9323 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9324 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9325 during interrupts. Ensure WSAVE is located at a shared bank address.
9326 2. Fixed page selection in some places
9327 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9328 the registers name strings.
9329 4. Fixed "signed / unsigned compare" compiler warnings.
9330 5. The PIC port manages its own allocation of the general purpose
9331 registers, but makes no attempt to reuse them. As a result when
9332 compiling it soon runs out of general purpose registers. Some
9333 additional code was added to the files pcode.c and device.c to walk
9334 through the function call tree and rename the registers so that they
9344 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

9351 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9353 Made bitfield a distinct type from bit so that bitfields
9354 convert as per ANSI C and bits retain their traditional
9355 boolean style behaviour. Implemented bitfield support in
9363 * src/ds390/gen.c: bit v bitfield split
9364 * src/z80/gen.c: New support for bitfields
9365 * support/regression/tests/bitfields.c: reenabled z80,
9368 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9370 Rules 246.x, 247.x relate to bitfields, the others speed up
9371 access to xdata mapped I/O devices.
9373 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9375 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9377 Cleaned up genPackBits and genUnpackBits and added two helper
9378 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9379 for literal assignments in genPackBits (thanks to Frieder for
9385 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9387 Fixed bug #748310 (pointer to function type mishandled when the
9388 function name is omitted). Also fixed a SIGSEGV when a function
9389 attribute (reentrant, etc) is used on a non-function or on a
9390 function but misplaced before the parameter list.

9417 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9419 Made the constant following the "interrupt" keyword optional. If
9420 omitted, the function will not automatically be given an entry
9421 in the interrupt vector table (similar to #pragma NOIV, but
9422 less syntacticly kludgy). The interrupt number is also now
9423 range checked. Also fixed a bug in the high order bit example

9944 it can be defined with CFLAGS when running configure
9945 * src/SDCCmain.c: fixed compiling + linking with object files
9947 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9950 added --disable-pic16-port
9951 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9952 * src/SDCCmain.c: linkOptions is changed to set *,
9953 added if/endif conditional macros to remove options help
9954 messages from optionsTable when a port is not configured, added
9955 support for the PIc16 port in the ports table, when executing
9956 the compiler with no port specified on command line, a default
9957 port is selected with the new macro DEFAULT_PORT which is
9958 defined in port.h, in setDefaultOptions() linkOptions is removed
9959 from initialization assignment, since now it is a set,
9960 parseCmdLine uses setParseWithComma for linkOptions, in
9961 linkEdit() linkOptions are accessed with new function indexSet()
9962 which returns the i'th item of a set variable. See SDCCset.c, in
9963 linkEdit() when calling buildCmdLine(), added linkOptions as
9964 last argument. Now users can pass arguments to gplink via the
9965 -Wl option, main() uses pic16glue() to glue up pic16 programs

9977 * src/pic16/glue.c: commented out some error producing lines
9978 * src/pic16/main.c: __config directives are commented out to stop
9979 gpasm complaining and test the linkage with gplink, _linkCmd and
9980 _asmCmd changed to be more gplink and gpasm friendly
9981 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9982 produced an error when parsed, peep rule 12 is added to utilize
9983 movff, but it is commented out since the pCode does not support
9984 yet a command with 2 address arguments
9986 2003-05-18 <johan AT balder>
9988 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11049 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11051 * in /sdcc/as/mcs51/ changed these files in order to create an
11052 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11053 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11054 following files to include the previous two files: aslink.dsp,
11055 Makefile.aslink, Makefile.bcc, and Makefile.in.
11057 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11058 .adb instead of .cdb
11060 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11062 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11063 value from option --iram-size.
11065 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11067 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11070 2002-09-18 <wiml AT hhhh.org>
11072 * SDCClrange.h: exposed setFromRange() and setToRange()
11073 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11074 packRegsForAccUse() (bug 542397)
11075 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11076 multiple times and emitting the fetch operations more than once
11077 added aopGetUsesAcc() function to allow binary operators to
11078 fetch their operands in the correct order; made genMinus() emit
11079 compact code for X = LITERAL - Y
11081 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11082 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11083 sprintf() in line 1267.
11085 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11086 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11089 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11090 Changes to aslink (All the changes are marked with 'JCF'):
11092 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11095 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11096 area BSEG. Also moves, if possible, the DATA area down into the internal
11097 ram so more space is available.
11099 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11102 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11103 not bytes. Function summary() which creates a memory usage summary
11104 file with extension .mem. Reports of overlaping stack and small stack
11105 size. If the space for the stack is less than 16 bytes aslink trows a
11108 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11109 the 8051. Option 'y' for memory summary output file.
11111 Changes to sdcc (All the changes are marked with 'JCF'):
11113 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11115 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11116 overlaying area for it (uses RegBankUsed[4]).
11118 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11119 bank zero as used by default. By default aslink locates the stack
11120 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11121 the creation of the .mem file. Delegates the allocation of data area
11122 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11123 the begining of the stack area to aslink.
11125 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11126 glue() in SDCCglue.c creates an area for it.
11128 2002-09-03 Borut Razem <borut.razem AT siol.net>
11129 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11130 sdcc/src/pic/glue.c:
11131 introduced atexit() handler for teporay files removal in case of
11132 errors, assertions, ...
11134 2002-08-29 Borut Razem <borut.razem AT siol.net>
11135 * sdcc/support/cpp2/auto-host_vc_in.h:
11136 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11137 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11138 Maybe there is a similar problem with BORLANDC? It should be checked!
11140 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11141 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11142 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11143 was not executed, and the compiler (cl) launched a warning:
11144 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11146 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11147 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11149 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

11158 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11159 - added Release configuration in VS projects
11160 - review of compiler an linker options
11161 - VC .exe files are generated in bin_vc directory, not to interfere
11162 with binaries generated from other projects (cygwin, mingw, bcc ...)
11164 * sdcc/src/yacc.dsp: added
11166 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11167 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11168 and insert the version number definitions from .version
11170 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11172 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11173 added - genarate auto-host.h using auto-host_vc_in.h as template
11176 removed from CVS, generated automatically

11179 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11181 2002-08-11 Borut Razem <borut.razem AT siol.net>
11182 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11184 2002-08-10 Borut Razem <borut.razem AT siol.net>
11185 * src/SDCCmain.c (main):
11186 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11187 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11188 The consequence was that some temporary files were not removed.
11191 unification of code in functions tempfilename() and tempfile():
11192 function tempnam() is defined in Visual Studio 6.0 and .NET
11194 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11196 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11197 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11198 - removed compiler command line option /WX: Treats all warnings as errors
11199 - update a list of source files, included into the project
11201 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11202 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11203 changed project type to Generic Project so that can be correcly converted to VS.NET project
11205 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11207 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11209 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11211 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11212 added return 0 statements after assert() to make compiler happy
11214 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11215 added newline in the def file to keep MSC compiler satisfied
11217 * sdcc/src/z80/gen.c:
11218 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11219 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11220 - solved MSC error in function aopDump()
11222 * sdcc_vc.h: define PREFIX as "\\sdcc"
11224 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11400 Previous fix was not good. basic blocks that have "break" or "return" are
11401 not really partof a loop , but live ranges used in these blocks should
