1165 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1167 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1168 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1170 One basic decision: e.g. src/clean.mk includes further files. In order
1171 to make this work there are two solutions:
1172 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1173 run configure on them. This way they can use
1174 'include $(srcdir)/port-clean.mk'
1175 - always include clean.mk by the Makefile at the same level. To avoid
1176 that `make clean` tries to include and build Makefile.dep the
1177 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1178 implemented, because now even `make uninstall` doesn't create
1179 Makefile.in. clean.mk could be eliminated by pasting it in
1182 * debugger/mcs51/Makefile.in: build own objects from library sources
1183 (SLIB, SDCC) in current directory
1185 * configure, configure.in: renamed --disable-device-lib-build in
1186 --disable-device-lib; added --enable-doc, the required tools are
1187 searched by configure; added result message; the toolchain for the
1188 belonging ports are now only built, if the port is enabled.
1190 * support/regression/*: all output is written in directory gen, because
1191 the fwk and ports directories don't livet in the build tree using vpath
1193 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1194 --disable-device-lib, added --enable-doc, added section VPATH
1196 * sim/ucsim/configure.in,
1197 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1198 z80 are enabled by default
1200 2006-04-24 Raphael Neider <rneider AT web.de>
1202 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1203 to config word, "pic14_"-prefixed some extern functions
1204 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1205 config word has been found
1206 * src/pic/device.h: added prototypes
1207 * src/pic/pcode.c: added "pic14_"-prefix where needed
1208 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1210 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
1212 (pic14emitRegularMap): ignore config words,
1213 (pic14createInterruptVect): moved generating __config directives away
1214 (picglue): have __config directives emitted
1216 2006-04-24 Borut Razem <borut.razem AT siol.net>

1222 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
1223 registers that have not been assigned proper liveranges,
1224 fixes #1469504 and #1474602,
1225 (pCodeRegOptimizeRegUsage): fixed typo in comment

1471 implemented patch 1120823 Thanks to Willy De la Court (normal
1472 interrupts need an interrupt number now if they are made critical),
1473 and enabled nesting of critical functions though not for gbz80
1474 (genCritical, genEndCritical): added functions
1475 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1476 * src/z80/mappings.i: added "ei" to all mappings

1488 the left operand is shorter than the result (c* = lit-c* + int),
1490 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1493 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1495 * src/.version: increased version number to 2.5.5
1496 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1497 linking is done manually in pic16 port's _linkEdit,
1498 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1499 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1500 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1501 allocate asmop as AOP_ACC,
1502 (aopForRemat): added parameter 'bool result' in function declaration,
1503 (pic16_aopGet): return AOP_ACC when accessing WREG,
1504 (pic16_popGetTempReg): minor modification,

1515 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1516 call to allocReg, not by manually allocating a new one,
1517 (pic16_assignRegisters): now before going through the register
1518 allocating functions mark all registers as free. This eliminates some
1519 side effects resulting from peephole parser done earlier in the backbone
1521 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1579 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1580 which dumps before the function entry point a data byte which represents
1581 the number of the local variables used by the specified function, added
1582 'xinst' for initial support for Extended Instruction Support,
1583 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1584 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1585 port->fun_prefix anymore (may change later),
1586 (genFunction, genEndFunction): do not store/restore local registers for
1587 _main (this should take care the --main-return command line option in
1589 (genOr): removed some legacy pic-port instructions,
1590 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1591 performing operations with SFR's causes data to be written more than
1592 once to each SFR. Perhaps SFRs should be handled in special cases...
1593 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1595 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1596 into account for stack starting position,

1598 --extended or -y for Extended Instruction Support,
1599 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1600 (deassignLRs): *** perhaps the most important change, old 'for' code
1601 (commented out for reference), didn't account for some registers which
1602 were left marked 'not free' after a pointer operation. The change
1603 reduces register usage a lot in some cases

3853 _do_cinit function, because the previous failed when local variables
3854 where not placed in the same memory bank,
3855 * device/lib/pic16/libsdcc/char/: various modifications to improve
3856 library performance,
3857 * doc/sdccman.lyx: some reorganization of the PIC16 part, added many
3858 information on the new functions of the c library and more...
3860 2005-03-28 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3862 * src/SDCCBBlock.c (iCodeBreakDown): fixed bug #1170212
3864 2005-03-26 Raphael Neider <rneider AT web.de>

3867 if condition == CARRY)
3868 * (genCmp): adapted to new genSkipc semantics
3869 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
3870 on rIfx (genCmp was broken)
3872 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3874 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3875 * src/z80/main.c (_keywords[]),
3876 * src/SDCCglobal.h (struct options),
3878 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3879 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3880 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3881 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3882 always available in leading double underscore form. The C99 support is
3883 mostly missing, but it's a start.
3884 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3885 reserved identifier "__data".
3887 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3889 * src/mcs51/peeph.def: fixed bug 1170013
3891 2005-03-22 Maarten Brock <sourceforge.brock AT dse.nl>

3897 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
3900 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3902 * src/port.h (struct PORT),

3930 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3931 immedDom() returning wrong block; probably fixes bug #1160833)
3933 2005-03-20 Borut Razem <borut.razem AT siol.net>
3935 * support/scripts/inc2h.pl: WIN32 port
3937 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3939 * device/lib/makefile.in: added abs.c and labs.c
3941 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3943 * device/include/stdint.h: added
3944 * device/lib/abs.c: added
3945 * device/lib/labs.c: added
3946 * device/include/stdlib.h: added abs() and labs() prototypes

3961 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3963 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3965 * device/lib/printf_large.c: removed inline assembly for portability and
3966 readability. Use printf_fast if speed or size are more important.
3967 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3968 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3970 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3972 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3973 prevent compiler warning
3975 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3977 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3978 moved to level 0 and declared as static. Also they are explicit
3979 placed in access bank. This was necessery because some times they
3980 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3981 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3982 optimizations. Currently only compare to unsigned char is implemented,
3983 * src/pic16/gen.c: added fReturnIdx array,
3984 * (struct resolvedIfx) is moved to gen.h and made public,
3985 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3986 * (aopForSym): added an optimization to directly store in stack of
3987 the operand of a SEND iCode,
3988 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3989 but as registers instead (AOP_REG) using the fReturnIdx array,
3990 * (pic16_freeAsmop): remove the freed register from the
3991 _G.sregsAlloc field,
3992 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3993 a compare of 'WREG',
3994 * (pic16_popGetTempRegCond): changed function prototype, now
3995 function takes also a bitVector argument v which holds the current
3996 set of registers that are allocated for stack access by aopForSym,
3997 registers allocated in aopForSym for accessing stack symbols are not
3998 any more part of the functions usedRegs field,
3999 * (genCall): some times aopOp is called for a stack variable to be
4000 send, aopForSym might perform the push, if this is true make sure
4001 that genCall doesn't push the variable twice by testing _G.resDirect,
4002 * (genFunction): changed testing for unspecified interrupt number
4003 from 256 to INTNO_UNSPEC,
4004 * modified selection scheme of frame pointer generation. Previously
4005 if function did use local registers a frame pointer was generated,
4006 now a frame pointer is generated only if function has arguments
4007 (that need PLUSW2 register access), or has stack arguments, or the
4008 compiler is not instructed to omit the frame pointer,
4009 * (genEndFunction): before restoring local registers that were saved
4010 in the function preamble, also restore the registers that *might*
4011 have been allocated for stack access,
4012 * (genRet): removed some old comments,
4013 * (genCmp, the active (RN's) version): added a call to the
4014 pic16_genCmp_special function to perform the compare with a more
4015 robust and optimized way,
4016 * (genInline): a feature has been added in inline code generation,
4017 which allows a wildcard variable substitution when writing inline
4018 assembly. Code is incomplete and experimental therefore undocumented,
4019 * (genCast): changed order of aopOp for result and right to allow
4020 aopForSym to directly load the result if possible,
4021 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4022 perform an optimized compare on some selected special occasions,
4023 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4024 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4025 generate an IVT any more,
4026 * src/pic16/main.c (pic16_optionsTable): added command line option
4028 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4029 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4031 * src/pic16/NOTES: Raphael Neider added in list of active developers
4032 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4033 jumptable_end to prevent bug #,
4034 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4035 inCond and outCond fields,
4036 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4037 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4038 turn off register spilling,
4039 * (packRegsForOneUse): synced with other ports' versions although it
4040 is not used currently,
4041 * (pic16_packRegisters): added an optimization while reading
4042 structure bitfields, some registers may be saved (malloc code is
4043 decreased by 80 bytes)
4045 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4047 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4048 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4049 this can be optimized more?
4051 2005-03-10 Raphael Neider <rneider AT web.de>
4053 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4054 genNearPointerGet): (hopefully) fixed access to bitfields via
4055 pointers (p->bitN = x; and x = p->bitN; failed)
4057 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4244 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4245 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4246 this might fix SIGSEGVs on MinGW...
4247 * src/SDCCopt.c (killDeadCode): restored original behaviour
4248 (volatile operands might get thrown away though)
4250 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

4290 macro STACK_MODEL_{SMALL/LARGE} when compiling and assembling to
4291 reflect stack model used,
4292 * src/pic16/ralloc.c (pic16_allocDirReg): when operand is allocated
4293 on stack return NULL,

4297 * src/SDCCopt.c (killDeadCode): do not throw iCodes away if one
4298 of the operands is volatile. Fixes #1020220
4300 2005-01-22 Daniel Winkler <post AT danielwinkler.de>

4730 be extensively tested in the future. Standard disclaimer here.
4731 Library is not automatically build yet. But one can build it by

7773 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7775 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7776 loaded with the linker search paths (-L arguments) and the libraries
7777 to be linked with the current source (-l arguments). Changes
7778 currently will affect only the pic16 port.
7779 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7780 include path the port specific paths and port specific libraries,
7781 * gplink command now contains the $3 argument,
7782 * src/pic16/device.h,
7783 * src/pic16/device.c,: structure PIC_device is made public and
7784 renamed to PIC16_device, the same for variable Pics which is renamed

7799 Documenting changes from previous commits.
7800 * configure.in (version 1.56),
7801 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7802 when generating output files to configure the pic16 library,
7803 but now I've commented it out, since gputils aren't installed in the
7804 SF compile farm, so library won't compile
7806 * device/lib/Makefile.in (version 1.56): initially I've added in
7807 target 'all' the prerequestive 'model-pic16' so it compiled the
7808 pic16 library, but now I've commented it out for the same reasons
7810 * added targets 'model-pic16' and 'objects-pic16' to compile the
7812 * added target 'port-specific-objects-pic16' to handle the
7813 generated libraries and copy them into the build/ directory
7814 * added target 'clean-intermediate-pic16' to clean intermediate
7815 files into pic16 directory
7816 * in target 'installdirs' added line to create directory pic16 in
7817 the installation path
7819 * device/include/Makefile.in (version 1.11): in target 'install'
7820 added lines to copy all header files to installation path,
7821 * in target 'installdirs' added line create directory for pic16
7822 headers in the installation path

7837 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7838 option so that it actually works. Made it specific to the z80, since
7839 the gbz80 doesn't have these kinds of I/O ports.

7867 via literal number. The symbol is placed in the corresponding
7868 position of the data ram
7869 * (pic16_dump_section): relocatable and absolute uninitialized
7870 data are now emitted in sorted order to reduce section naming,
7871 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7872 weren't marked as being in the access bank,
7874 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7876 Added portion of GNU PIC Library under the directory
7877 device/include/pic16 and device/lib/pic16. These files
7878 contain the declarations of SFRs for the PIC18Fxx2 devices.

7909 all over. Telling LaTeX to be less strict with word spacing
7910 to better keep the right margin. Changed some notes about
7911 maintainance of the ports in section 3.2.1 - is it OK like this?
7913 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7951 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7953 * src/pic16/peeph.def: all peepholes with movff are commented out,
7954 because there is a problem in the pcode peep optimizer,
7955 * src/pic16/ralloc.c: the register allocator can now reuse local

7957 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7959 Added file src/pic16/NOTES with information about program writing on
7960 the current port version.

7992 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7995 * src/z80/main.c: added missed needLinkerScript flags (more than
7996 one port structure defined in these file)
7997 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

8013 needLinkerScript flag
8015 * src/pic16/gen.c (genAddrOf): fixed bug #863624
8016 * src/pic/glue.c: added variable udata_section_name to
8017 override default uninitialized data segment definition for
8018 devices only with SHAREBANK memory (reported from Erik Epetrich)
8019 * (pic14emitOverlay): modified to emit a commented overlay segment
8020 directive when no overlay data exist
8021 * (picglue): modified to emit uninitialized data segment
8022 according to udata_section_name

8027 arguments via -W option
8028 * src/pic16/main.c: added $l in _asmCmd, changed extension for
8029 object file from '.rel' to '.o' in port->linker structure,

8032 2004-01-07 Borut Razem <borut.razem AT siol.net>
8034 * support/scripts/sdcc.nsi: update PATH
8035 * support/scripts/sdcc.ico: craeted

8042 2004-01-07 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8044 * src/SDCCsymt.c (processFuncArgs): fixed superflous allocation noted
8046 * src/SDCCmem.c (printAllocInfoSeg, printAllocInfo): minor changes to

8048 include information about variables allocated to the overlay
8051 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8053 * as/mcs51/lkmain.c: Help about -Y option

8065 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8067 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8068 (default behaviour).
8070 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8072 A python script to validate compiler diagnostic messages. It can be
8073 used to verify that sdcc complains about bad c source code and
8074 gives a good location of the error.
8075 * support/valdiag/Makefile,
8076 * support/valdiag/valdiag.py,
8077 * support/valdiag/tests/*
8079 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8081 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),

8092 * src/common.h: added ifndef/define/endif macros
8093 around the header file.
8094 Bug reported from Jesus Calvino-Fraga
8096 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8098 * sdcc.spec: updated
8099 * device/include/Makefile.in: don't install CVS directories
8100 * device/lib/Makefile.in: added removal of CVS directories after install
8101 * doc/Makefile: fixed install, added local_icons
8102 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8103 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8104 * src/ds390/gen.c (genRightShift): fixed bug #870788
8105 * src/SDCCast.c (decorateType): fixed bug #870781
8107 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8109 PIC16 port related changes:
8110 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8111 added variable stackPos,
8113 * gen.c: genCall, assignResultValue: added support for
8114 pushing/retrieving function parameters to/from stack,
8115 genFunction,genEndFunction: setup stack frame for the
8117 genAddrOf: will be changed according to bug 863624
8119 * added files genutils.c and genutils.h which contain gen*
8120 debugged and optimised functions extracted from gen.c
8122 * glue.c: added variable 'externs' which holds extern symbols,
8123 pic16emitRegularMap: is modified to properly handle relocatable
8124 symbols under the new scheme,
8125 pic16createInterruptVect: is modified
8126 pic16printPublics: is modified to emit 'global' assembler directives,
8127 added pic16_printExterns to print extern symbols,
8128 pic16glue: initializes stack/frame pointer in the beginning of
8129 the assembly output. Temporary hack, will be corrected later,
8130 because gplink yet does not support stack and SDCC does not
8131 yet support a type of crt0.o object to create the final binary.
8133 * Removed many lines that contain 8051 legacy code.
8134 * The code is finally placed under a 'code' directive.
8135 * Added port specific options.
8137 * _process_pragma: simplified since now we do not need *special*
8138 include file to define SFR registers. But a separate header
8139 will be needed. This will be developed later.
8140 * _pic16_parseOptions: added, parses port specific options:
8141 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8142 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8143 --preplace-udata-with=
8145 * _pic16_setDefaultOptions: modified to initialize section names,
8146 but hack is temporarly out of order since it needs improvement.
8147 * _pic16_genAssemblerPreamble: configuration words are emitted by
8148 their address instead of their name. This part is incomplete and
8149 supports only the 18Fxx2 devices. Other devices will emit an error
8150 during assembly since they do not contain the same set of config
8152 * _pic16_genIVT: is modified,
8154 * pcode.c: added definitions for some hardware registers that are needed
8156 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8157 All PCI entries are updated. Now LFSR is supported.
8158 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8159 * added pic16_newpCodeOpLit2 to support instructions with
8160 two literal arguments
8161 * pic16_pCode2str: corrected code that emits assembler instructions
8162 with two literal operands and those that have an access bit modifier
8163 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8164 this fixes a bug which caused some labels to be lost, when an
8165 assembler directive was added, i.e. banksel,
8166 * pic16_FixRegisterBanking: improved logic that causes the insertion
8168 * InlineFunction: functions that are called once, are not any more
8169 inlined. This can be a port option in the future,
8171 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8173 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8174 hold the corresponding uninitialized symbols,
8175 * pic16_allocProcessorRegister: registers have explicit marked the
8177 * pic16_allocInternalRegister: registers are explicit marked as
8179 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8180 processing list, so bit registers were lost,
8183 * ralloc.h: added field 'accessBank' and original symbol operand
8184 in register definition,
8185 * removed the field isMapped from register definition,
8187 ** Several functions have been removed from various sources:
8188 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8189 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8190 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8191 pic16_assignRelocatableRegisters
8193 ** others have been introduced:
8194 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8195 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8197 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8199 * support/scripts/inc2h.pl: changed definition of BIT_AT
8200 to emit 'sbit at' instead of 'bit at'. This was a request.
8202 PIC16 port related preliminary changes:
8203 * gen.c: prefixed function popRegFromString with
8204 pic16_ and all references to it corrected
8205 * pcode.c: all pic16_pc_* hardware registers prefixed
8206 with underscore (_),
8207 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8208 * ralloc.c: newReg(): when register is REG_SFR then
8209 set address to rIdx,
8210 pic16_allocProcessorRegister(): marks register wasUsed=0
8211 pic16_writeUsedRegs(): added a call to assign processor
8212 registers via pic16_assignFixedRegisters
8214 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8216 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8217 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8218 variables in unused register banks. Also the SSEG is placed
8219 wherever there is enough space for it, and IDATA can be anywhere
8220 in internal RAM. For now compile using -Wl-Y[stack_size].
8221 The mem file is different for this option as well, since it
8222 makes no sense of talking about DSEG lenght.
8224 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8226 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8227 in certain cases, e.g. when ROM assignment, patch provided
8228 from Albert den Haan.
8230 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9253 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9254 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9255 type for bits was changed. It resulted in bit variables becoming
9256 global, which is not permitted in PIC 14 assembly output.

9273 A few small changes that speed up the peephole optimizer.
9277 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9279 Try to make the peephole optimizer smarter by maintaining
9280 an association between the assembly source code and the
9281 iCodes that originated them. Put this information to use
9282 with a new peephole rule condition "notVolatile" so that
9283 the rules can be aggressive yet still safe.
9288 * src/mcs51/peeph.def
9290 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9294 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9295 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9296 if the left or right operand symbols have the accuse flag set.
9298 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9300 Changed the type of the result of the ! (NOT) operator to char;
9301 previously it returned the same type as the source. This allows
9302 us to eliminate all the genFloatNot functions (all of its target
9303 implementations were very buggy) since !float can use the same
9306 * src/SDCCicode.c (ast2iCode): ! returns char

9315 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9316 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9317 during interrupts. Ensure WSAVE is located at a shared bank address.
9318 2. Fixed page selection in some places
9319 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9320 the registers name strings.
9321 4. Fixed "signed / unsigned compare" compiler warnings.
9322 5. The PIC port manages its own allocation of the general purpose
9323 registers, but makes no attempt to reuse them. As a result when
9324 compiling it soon runs out of general purpose registers. Some
9325 additional code was added to the files pcode.c and device.c to walk

9412 omitted, the function will not automatically be given an entry
9413 in the interrupt vector table (similar to #pragma NOIV, but
9414 less syntacticly kludgy). The interrupt number is also now
9415 range checked. Also fixed a bug in the high order bit example

9918 * src/pic16/pcode.c: Cleaned warnings
9919 * src/pic16/pcodeflow.c: Cleaned warnings
9920 * src/pic16/pcoderegs.c: Cleaned warnings
9922 2003-05-19 Scott Dattalo <scott AT dattalo.com>
9924 * src/pic16/pcode.c: Cleaned warnings
9925 * src/pic16/pcodepeep.c: Cleaned warnings
9926 * src/pic16/ralloc.c: Cleaned warnings

9930 * doc/sdccman.lyx: fixed bug 739745
9931 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
9933 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9935 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9936 it can be defined with CFLAGS when running configure
9937 * src/SDCCmain.c: fixed compiling + linking with object files
9939 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9941 * configure.in: configure for pic16 port,
9942 added --disable-pic16-port
9943 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9944 * src/SDCCmain.c: linkOptions is changed to set *,
9945 added if/endif conditional macros to remove options help
9946 messages from optionsTable when a port is not configured, added
9947 support for the PIc16 port in the ports table, when executing
9948 the compiler with no port specified on command line, a default
9949 port is selected with the new macro DEFAULT_PORT which is
9950 defined in port.h, in setDefaultOptions() linkOptions is removed
9951 from initialization assignment, since now it is a set,
9952 parseCmdLine uses setParseWithComma for linkOptions, in
9953 linkEdit() linkOptions are accessed with new function indexSet()
9954 which returns the i'th item of a set variable. See SDCCset.c, in
9955 linkEdit() when calling buildCmdLine(), added linkOptions as
9956 last argument. Now users can pass arguments to gplink via the
9957 -Wl option, main() uses pic16glue() to glue up pic16 programs
9958 * src/SDCCpeeph.c: various changes to support pic16
9959 * src/SDCCset.c: added function void *indexSet(set *, int) to
9960 return the i'th item of the set

9962 * src/SDCCsymt.c: in checkSClass(), added support for PIC16
9963 * src/clean.mk: added pic16 in CLEANALLPORTS variable
9964 * src/port.h: added TARGET_ID_PIC16,TARGET_IS_PIC16 macro,
9965 added macro DEFAULT_PORT
9966 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
9967 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
9969 * src/pic16/glue.c: commented out some error producing lines
9970 * src/pic16/main.c: __config directives are commented out to stop
9971 gpasm complaining and test the linkage with gplink, _linkCmd and
9972 _asmCmd changed to be more gplink and gpasm friendly
9973 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9974 produced an error when parsed, peep rule 12 is added to utilize
9975 movff, but it is commented out since the pCode does not support
9976 yet a command with 2 address arguments
9978 2003-05-18 <johan AT balder>
9980 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10007 2003-05-11 Borut Razem <borut.razem AT siol.net>
10009 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
10010 the path of bin directory, so that PATH is the only env. variable, which has to be set
10011 in case of standard installation.

11041 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11043 * in /sdcc/as/mcs51/ changed these files in order to create an
11044 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11045 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11046 following files to include the previous two files: aslink.dsp,
11047 Makefile.aslink, Makefile.bcc, and Makefile.in.
11049 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11050 .adb instead of .cdb
11052 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11054 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11055 value from option --iram-size.
11057 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11059 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11062 2002-09-18 <wiml AT hhhh.org>
11064 * SDCClrange.h: exposed setFromRange() and setToRange()
11065 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11066 packRegsForAccUse() (bug 542397)
11067 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11068 multiple times and emitting the fetch operations more than once
11069 added aopGetUsesAcc() function to allow binary operators to
11070 fetch their operands in the correct order; made genMinus() emit
11071 compact code for X = LITERAL - Y
11073 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11074 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11075 sprintf() in line 1267.
11077 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11078 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11081 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11082 Changes to aslink (All the changes are marked with 'JCF'):
11084 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11087 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11088 area BSEG. Also moves, if possible, the DATA area down into the internal
11089 ram so more space is available.
11091 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11094 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11095 not bytes. Function summary() which creates a memory usage summary
11096 file with extension .mem. Reports of overlaping stack and small stack
11097 size. If the space for the stack is less than 16 bytes aslink trows a
11100 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11101 the 8051. Option 'y' for memory summary output file.
11103 Changes to sdcc (All the changes are marked with 'JCF'):
11105 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11107 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11108 overlaying area for it (uses RegBankUsed[4]).
11110 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11111 bank zero as used by default. By default aslink locates the stack
11112 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11113 the creation of the .mem file. Delegates the allocation of data area
11114 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11115 the begining of the stack area to aslink.
11117 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11118 glue() in SDCCglue.c creates an area for it.
11120 2002-09-03 Borut Razem <borut.razem AT siol.net>
11121 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11122 sdcc/src/pic/glue.c:
11123 introduced atexit() handler for teporay files removal in case of
11124 errors, assertions, ...
11126 2002-08-29 Borut Razem <borut.razem AT siol.net>
11127 * sdcc/support/cpp2/auto-host_vc_in.h:
11128 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11129 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11130 Maybe there is a similar problem with BORLANDC? It should be checked!
11132 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11133 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11134 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11135 was not executed, and the compiler (cl) launched a warning:
11136 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11138 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11139 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

11151 - added Release configuration in VS projects
11152 - review of compiler an linker options
11153 - VC .exe files are generated in bin_vc directory, not to interfere
11154 with binaries generated from other projects (cygwin, mingw, bcc ...)
11156 * sdcc/src/yacc.dsp: added
11158 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11159 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11160 and insert the version number definitions from .version

11164 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11165 added - genarate auto-host.h using auto-host_vc_in.h as template
11168 removed from CVS, generated automatically
11170 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11171 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11173 2002-08-11 Borut Razem <borut.razem AT siol.net>
11174 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11176 2002-08-10 Borut Razem <borut.razem AT siol.net>
11177 * src/SDCCmain.c (main):
11178 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11179 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11180 The consequence was that some temporary files were not removed.
11183 unification of code in functions tempfilename() and tempfile():
11184 function tempnam() is defined in Visual Studio 6.0 and .NET
11186 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11188 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11189 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11190 - removed compiler command line option /WX: Treats all warnings as errors
11191 - update a list of source files, included into the project
11193 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11194 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11195 changed project type to Generic Project so that can be correcly converted to VS.NET project
11197 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11199 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11201 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11203 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11204 added return 0 statements after assert() to make compiler happy
11206 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11207 added newline in the def file to keep MSC compiler satisfied
11209 * sdcc/src/z80/gen.c:
11210 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11211 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11212 - solved MSC error in function aopDump()
11214 * sdcc_vc.h: define PREFIX as "\\sdcc"
11216 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11272 were not getting allocated.
11274 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>

11389 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11391 * sdcc/src/SDCCloop.c:
11392 Previous fix was not good. basic blocks that have "break" or "return" are
11393 not really partof a loop , but live ranges used in these blocks should
