1155 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1157 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1158 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1160 One basic decision: e.g. src/clean.mk includes further files. In order
1161 to make this work there are two solutions:
1162 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1163 run configure on them. This way they can use
1164 'include $(srcdir)/port-clean.mk'
1165 - always include clean.mk by the Makefile at the same level. To avoid
1166 that `make clean` tries to include and build Makefile.dep the
1167 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1168 implemented, because now even `make uninstall` doesn't create
1169 Makefile.in. clean.mk could be eliminated by pasting it in
1172 * debugger/mcs51/Makefile.in: build own objects from library sources
1173 (SLIB, SDCC) in current directory
1175 * configure, configure.in: renamed --disable-device-lib-build in
1176 --disable-device-lib; added --enable-doc, the required tools are
1177 searched by configure; added result message; the toolchain for the
1178 belonging ports are now only built, if the port is enabled.
1180 * support/regression/*: all output is written in directory gen, because
1181 the fwk and ports directories don't livet in the build tree using vpath
1183 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1184 --disable-device-lib, added --enable-doc, added section VPATH
1186 * sim/ucsim/configure.in,
1187 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1188 z80 are enabled by default
1190 2006-04-24 Raphael Neider <rneider AT web.de>
1192 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1193 to config word, "pic14_"-prefixed some extern functions
1194 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1195 config word has been found
1196 * src/pic/device.h: added prototypes
1197 * src/pic/pcode.c: added "pic14_"-prefix where needed
1198 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1200 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
1202 (pic14emitRegularMap): ignore config words,
1203 (pic14createInterruptVect): moved generating __config directives away
1204 (picglue): have __config directives emitted

1214 fixes #1469504 and #1474602,
1215 (pCodeRegOptimizeRegUsage): fixed typo in comment

1462 interrupts need an interrupt number now if they are made critical),
1463 and enabled nesting of critical functions though not for gbz80
1464 (genCritical, genEndCritical): added functions
1465 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1466 * src/z80/mappings.i: added "ei" to all mappings

1478 the left operand is shorter than the result (c* = lit-c* + int),
1480 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1483 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1485 * src/.version: increased version number to 2.5.5
1486 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1487 linking is done manually in pic16 port's _linkEdit,
1488 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1489 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1490 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1491 allocate asmop as AOP_ACC,
1492 (aopForRemat): added parameter 'bool result' in function declaration,
1493 (pic16_aopGet): return AOP_ACC when accessing WREG,
1494 (pic16_popGetTempReg): minor modification,

1505 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1506 call to allocReg, not by manually allocating a new one,
1507 (pic16_assignRegisters): now before going through the register
1508 allocating functions mark all registers as free. This eliminates some
1509 side effects resulting from peephole parser done earlier in the backbone
1511 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1569 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1570 which dumps before the function entry point a data byte which represents
1571 the number of the local variables used by the specified function, added
1572 'xinst' for initial support for Extended Instruction Support,
1573 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1574 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1575 port->fun_prefix anymore (may change later),
1576 (genFunction, genEndFunction): do not store/restore local registers for
1577 _main (this should take care the --main-return command line option in
1579 (genOr): removed some legacy pic-port instructions,
1580 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1581 performing operations with SFR's causes data to be written more than
1582 once to each SFR. Perhaps SFRs should be handled in special cases...
1583 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1585 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1586 into account for stack starting position,

1588 --extended or -y for Extended Instruction Support,
1589 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1590 (deassignLRs): *** perhaps the most important change, old 'for' code
1591 (commented out for reference), didn't account for some registers which
1592 were left marked 'not free' after a pointer operation. The change
1593 reduces register usage a lot in some cases

3847 * doc/sdccman.lyx: some reorganization of the PIC16 part, added many
3848 information on the new functions of the c library and more...
3850 2005-03-28 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3852 * src/SDCCBBlock.c (iCodeBreakDown): fixed bug #1170212
3854 2005-03-26 Raphael Neider <rneider AT web.de>
3856 * src/pic16/gen.c (genSkipc): fixed semantics (execute branch
3857 if condition == CARRY)
3858 * (genCmp): adapted to new genSkipc semantics
3859 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
3860 on rIfx (genCmp was broken)
3862 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3864 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3865 * src/z80/main.c (_keywords[]),
3866 * src/SDCCglobal.h (struct options),
3868 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3869 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3870 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3871 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3872 always available in leading double underscore form. The C99 support is
3873 mostly missing, but it's a start.
3874 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3875 reserved identifier "__data".
3877 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3879 * src/mcs51/peeph.def: fixed bug 1170013

3920 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3921 immedDom() returning wrong block; probably fixes bug #1160833)
3923 2005-03-20 Borut Razem <borut.razem AT siol.net>
3925 * support/scripts/inc2h.pl: WIN32 port
3927 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3929 * device/lib/makefile.in: added abs.c and labs.c
3931 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3933 * device/include/stdint.h: added
3934 * device/lib/abs.c: added
3935 * device/lib/labs.c: added
3936 * device/include/stdlib.h: added abs() and labs() prototypes

3951 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3953 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3955 * device/lib/printf_large.c: removed inline assembly for portability and
3956 readability. Use printf_fast if speed or size are more important.
3957 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3958 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3960 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3962 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3963 prevent compiler warning
3965 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3967 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3968 moved to level 0 and declared as static. Also they are explicit
3969 placed in access bank. This was necessery because some times they
3970 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3971 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3972 optimizations. Currently only compare to unsigned char is implemented,
3973 * src/pic16/gen.c: added fReturnIdx array,
3974 * (struct resolvedIfx) is moved to gen.h and made public,
3975 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3976 * (aopForSym): added an optimization to directly store in stack of
3977 the operand of a SEND iCode,
3978 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3979 but as registers instead (AOP_REG) using the fReturnIdx array,
3980 * (pic16_freeAsmop): remove the freed register from the
3981 _G.sregsAlloc field,
3982 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3983 a compare of 'WREG',
3984 * (pic16_popGetTempRegCond): changed function prototype, now
3985 function takes also a bitVector argument v which holds the current
3986 set of registers that are allocated for stack access by aopForSym,
3987 registers allocated in aopForSym for accessing stack symbols are not
3988 any more part of the functions usedRegs field,
3989 * (genCall): some times aopOp is called for a stack variable to be
3990 send, aopForSym might perform the push, if this is true make sure
3991 that genCall doesn't push the variable twice by testing _G.resDirect,
3992 * (genFunction): changed testing for unspecified interrupt number
3993 from 256 to INTNO_UNSPEC,
3994 * modified selection scheme of frame pointer generation. Previously
3995 if function did use local registers a frame pointer was generated,
3996 now a frame pointer is generated only if function has arguments
3997 (that need PLUSW2 register access), or has stack arguments, or the
3998 compiler is not instructed to omit the frame pointer,
3999 * (genEndFunction): before restoring local registers that were saved
4000 in the function preamble, also restore the registers that *might*
4001 have been allocated for stack access,
4002 * (genRet): removed some old comments,
4003 * (genCmp, the active (RN's) version): added a call to the
4004 pic16_genCmp_special function to perform the compare with a more
4005 robust and optimized way,
4006 * (genInline): a feature has been added in inline code generation,
4007 which allows a wildcard variable substitution when writing inline
4008 assembly. Code is incomplete and experimental therefore undocumented,
4009 * (genCast): changed order of aopOp for result and right to allow
4010 aopForSym to directly load the result if possible,
4011 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4012 perform an optimized compare on some selected special occasions,
4013 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4014 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4015 generate an IVT any more,
4016 * src/pic16/main.c (pic16_optionsTable): added command line option
4018 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4019 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4021 * src/pic16/NOTES: Raphael Neider added in list of active developers
4022 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4023 jumptable_end to prevent bug #,
4024 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4025 inCond and outCond fields,
4026 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4027 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4028 turn off register spilling,
4029 * (packRegsForOneUse): synced with other ports' versions although it
4030 is not used currently,
4031 * (pic16_packRegisters): added an optimization while reading
4032 structure bitfields, some registers may be saved (malloc code is
4033 decreased by 80 bytes)
4035 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4037 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4038 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4039 this can be optimized more?
4041 2005-03-10 Raphael Neider <rneider AT web.de>
4043 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4044 genNearPointerGet): (hopefully) fixed access to bitfields via
4045 pointers (p->bitN = x; and x = p->bitN; failed)
4047 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4234 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4235 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4236 this might fix SIGSEGVs on MinGW...
4237 * src/SDCCopt.c (killDeadCode): restored original behaviour
4238 (volatile operands might get thrown away though)
4240 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

4280 macro STACK_MODEL_{SMALL/LARGE} when compiling and assembling to
4281 reflect stack model used,
4282 * src/pic16/ralloc.c (pic16_allocDirReg): when operand is allocated
4283 on stack return NULL,

4288 of the operands is volatile. Fixes #1020220
4290 2005-01-22 Daniel Winkler <post AT danielwinkler.de>

7763 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7765 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7766 loaded with the linker search paths (-L arguments) and the libraries
7767 to be linked with the current source (-l arguments). Changes
7768 currently will affect only the pic16 port.
7769 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7770 include path the port specific paths and port specific libraries,
7771 * gplink command now contains the $3 argument,
7772 * src/pic16/device.h,
7773 * src/pic16/device.c,: structure PIC_device is made public and
7774 renamed to PIC16_device, the same for variable Pics which is renamed

7789 Documenting changes from previous commits.
7790 * configure.in (version 1.56),
7791 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7792 when generating output files to configure the pic16 library,
7793 but now I've commented it out, since gputils aren't installed in the
7794 SF compile farm, so library won't compile
7796 * device/lib/Makefile.in (version 1.56): initially I've added in
7797 target 'all' the prerequestive 'model-pic16' so it compiled the
7798 pic16 library, but now I've commented it out for the same reasons
7800 * added targets 'model-pic16' and 'objects-pic16' to compile the
7802 * added target 'port-specific-objects-pic16' to handle the
7803 generated libraries and copy them into the build/ directory
7804 * added target 'clean-intermediate-pic16' to clean intermediate
7805 files into pic16 directory
7806 * in target 'installdirs' added line to create directory pic16 in
7807 the installation path
7809 * device/include/Makefile.in (version 1.11): in target 'install'
7810 added lines to copy all header files to installation path,
7811 * in target 'installdirs' added line create directory for pic16
7812 headers in the installation path
7814 2004-01-13 Klaus Flittner <klaus_flittner AT gmx.de>

7825 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7827 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7828 option so that it actually works. Made it specific to the z80, since
7829 the gbz80 doesn't have these kinds of I/O ports.
7831 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7833 * device/include/z180.h,

7899 all over. Telling LaTeX to be less strict with word spacing
7900 to better keep the right margin. Changed some notes about
7901 maintainance of the ports in section 3.2.1 - is it OK like this?
7903 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7941 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7943 * src/pic16/peeph.def: all peepholes with movff are commented out,
7944 because there is a problem in the pcode peep optimizer,
7945 * src/pic16/ralloc.c: the register allocator can now reuse local

8038 include information about variables allocated to the overlay
8041 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8043 * as/mcs51/lkmain.c: Help about -Y option

8055 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8057 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8058 (default behaviour).
8060 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8062 A python script to validate compiler diagnostic messages. It can be
8063 used to verify that sdcc complains about bad c source code and
8064 gives a good location of the error.
8065 * support/valdiag/Makefile,
8066 * support/valdiag/valdiag.py,
8067 * support/valdiag/tests/*
8069 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8082 * src/common.h: added ifndef/define/endif macros
8083 around the header file.
8084 Bug reported from Jesus Calvino-Fraga
8086 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8088 * sdcc.spec: updated
8089 * device/include/Makefile.in: don't install CVS directories
8090 * device/lib/Makefile.in: added removal of CVS directories after install
8091 * doc/Makefile: fixed install, added local_icons
8092 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8093 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8094 * src/ds390/gen.c (genRightShift): fixed bug #870788
8095 * src/SDCCast.c (decorateType): fixed bug #870781
8097 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8099 PIC16 port related changes:
8100 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8101 added variable stackPos,
8103 * gen.c: genCall, assignResultValue: added support for
8104 pushing/retrieving function parameters to/from stack,
8105 genFunction,genEndFunction: setup stack frame for the
8107 genAddrOf: will be changed according to bug 863624
8109 * added files genutils.c and genutils.h which contain gen*
8110 debugged and optimised functions extracted from gen.c
8112 * glue.c: added variable 'externs' which holds extern symbols,
8113 pic16emitRegularMap: is modified to properly handle relocatable
8114 symbols under the new scheme,
8115 pic16createInterruptVect: is modified
8116 pic16printPublics: is modified to emit 'global' assembler directives,
8117 added pic16_printExterns to print extern symbols,
8118 pic16glue: initializes stack/frame pointer in the beginning of
8119 the assembly output. Temporary hack, will be corrected later,
8120 because gplink yet does not support stack and SDCC does not
8121 yet support a type of crt0.o object to create the final binary.
8123 * Removed many lines that contain 8051 legacy code.
8124 * The code is finally placed under a 'code' directive.
8125 * Added port specific options.
8127 * _process_pragma: simplified since now we do not need *special*
8128 include file to define SFR registers. But a separate header
8129 will be needed. This will be developed later.
8130 * _pic16_parseOptions: added, parses port specific options:
8131 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8132 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8133 --preplace-udata-with=
8135 * _pic16_setDefaultOptions: modified to initialize section names,
8136 but hack is temporarly out of order since it needs improvement.
8137 * _pic16_genAssemblerPreamble: configuration words are emitted by
8138 their address instead of their name. This part is incomplete and
8139 supports only the 18Fxx2 devices. Other devices will emit an error
8140 during assembly since they do not contain the same set of config
8142 * _pic16_genIVT: is modified,
8144 * pcode.c: added definitions for some hardware registers that are needed
8146 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8147 All PCI entries are updated. Now LFSR is supported.
8148 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8149 * added pic16_newpCodeOpLit2 to support instructions with
8150 two literal arguments
8151 * pic16_pCode2str: corrected code that emits assembler instructions
8152 with two literal operands and those that have an access bit modifier
8153 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8154 this fixes a bug which caused some labels to be lost, when an
8155 assembler directive was added, i.e. banksel,
8156 * pic16_FixRegisterBanking: improved logic that causes the insertion
8158 * InlineFunction: functions that are called once, are not any more
8159 inlined. This can be a port option in the future,
8161 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8163 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8164 hold the corresponding uninitialized symbols,
8165 * pic16_allocProcessorRegister: registers have explicit marked the
8167 * pic16_allocInternalRegister: registers are explicit marked as
8169 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8170 processing list, so bit registers were lost,
8173 * ralloc.h: added field 'accessBank' and original symbol operand
8174 in register definition,
8175 * removed the field isMapped from register definition,
8177 ** Several functions have been removed from various sources:
8178 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8179 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8180 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8181 pic16_assignRelocatableRegisters
8183 ** others have been introduced:
8184 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8185 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8187 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8189 * support/scripts/inc2h.pl: changed definition of BIT_AT
8190 to emit 'sbit at' instead of 'bit at'. This was a request.
8192 PIC16 port related preliminary changes:
8193 * gen.c: prefixed function popRegFromString with
8194 pic16_ and all references to it corrected
8195 * pcode.c: all pic16_pc_* hardware registers prefixed
8196 with underscore (_),
8197 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8198 * ralloc.c: newReg(): when register is REG_SFR then
8199 set address to rIdx,
8200 pic16_allocProcessorRegister(): marks register wasUsed=0
8201 pic16_writeUsedRegs(): added a call to assign processor
8202 registers via pic16_assignFixedRegisters
8204 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8206 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8207 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8208 variables in unused register banks. Also the SSEG is placed
8209 wherever there is enough space for it, and IDATA can be anywhere
8210 in internal RAM. For now compile using -Wl-Y[stack_size].
8211 The mem file is different for this option as well, since it
8212 makes no sense of talking about DSEG lenght.
8214 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8216 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8217 in certain cases, e.g. when ROM assignment, patch provided
8218 from Albert den Haan.
8220 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9243 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9244 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

9263 A few small changes that speed up the peephole optimizer.
9267 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9269 Try to make the peephole optimizer smarter by maintaining
9270 an association between the assembly source code and the
9271 iCodes that originated them. Put this information to use
9272 with a new peephole rule condition "notVolatile" so that
9273 the rules can be aggressive yet still safe.
9278 * src/mcs51/peeph.def
9280 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9284 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9285 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9286 if the left or right operand symbols have the accuse flag set.
9288 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9290 Changed the type of the result of the ! (NOT) operator to char;
9291 previously it returned the same type as the source. This allows
9292 us to eliminate all the genFloatNot functions (all of its target
9293 implementations were very buggy) since !float can use the same

9305 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9306 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9307 during interrupts. Ensure WSAVE is located at a shared bank address.
9308 2. Fixed page selection in some places
9309 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9310 the registers name strings.
9311 4. Fixed "signed / unsigned compare" compiler warnings.
9312 5. The PIC port manages its own allocation of the general purpose
9313 registers, but makes no attempt to reuse them. As a result when
9314 compiling it soon runs out of general purpose registers. Some
9315 additional code was added to the files pcode.c and device.c to walk
9316 through the function call tree and rename the registers so that they
9326 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

9333 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9335 Made bitfield a distinct type from bit so that bitfields
9336 convert as per ANSI C and bits retain their traditional
9337 boolean style behaviour. Implemented bitfield support in
9345 * src/ds390/gen.c: bit v bitfield split
9346 * src/z80/gen.c: New support for bitfields
9347 * support/regression/tests/bitfields.c: reenabled z80,
9350 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9353 access to xdata mapped I/O devices.
9355 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9357 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9359 Cleaned up genPackBits and genUnpackBits and added two helper
9360 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9361 for literal assignments in genPackBits (thanks to Frieder for
9367 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9369 Fixed bug #748310 (pointer to function type mishandled when the
9370 function name is omitted). Also fixed a SIGSEGV when a function
9371 attribute (reentrant, etc) is used on a non-function or on a
9372 function but misplaced before the parameter list.
9374 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9376 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

9399 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9401 Made the constant following the "interrupt" keyword optional. If
9402 omitted, the function will not automatically be given an entry
9403 in the interrupt vector table (similar to #pragma NOIV, but
9404 less syntacticly kludgy). The interrupt number is also now
9405 range checked. Also fixed a bug in the high order bit example

9426 unsigned, but are signed by default
9427 * src/SDCCval.c (constVal): rearranged
9428 * src/SDCCval.c (valMod): preliminary fix
9429 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9923 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9925 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9926 it can be defined with CFLAGS when running configure
9927 * src/SDCCmain.c: fixed compiling + linking with object files
9929 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9931 * configure.in: configure for pic16 port,
9932 added --disable-pic16-port
9933 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9934 * src/SDCCmain.c: linkOptions is changed to set *,
9935 added if/endif conditional macros to remove options help
9936 messages from optionsTable when a port is not configured, added
9937 support for the PIc16 port in the ports table, when executing
9938 the compiler with no port specified on command line, a default
9939 port is selected with the new macro DEFAULT_PORT which is
9940 defined in port.h, in setDefaultOptions() linkOptions is removed
9941 from initialization assignment, since now it is a set,
9942 parseCmdLine uses setParseWithComma for linkOptions, in
9943 linkEdit() linkOptions are accessed with new function indexSet()
9944 which returns the i'th item of a set variable. See SDCCset.c, in
9945 linkEdit() when calling buildCmdLine(), added linkOptions as
9946 last argument. Now users can pass arguments to gplink via the
9947 -Wl option, main() uses pic16glue() to glue up pic16 programs

9959 * src/pic16/glue.c: commented out some error producing lines
9960 * src/pic16/main.c: __config directives are commented out to stop
9961 gpasm complaining and test the linkage with gplink, _linkCmd and
9962 _asmCmd changed to be more gplink and gpasm friendly
9963 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9964 produced an error when parsed, peep rule 12 is added to utilize
9965 movff, but it is commented out since the pCode does not support
9966 yet a command with 2 address arguments
9968 2003-05-18 <johan AT balder>

9995 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9997 2003-05-11 Borut Razem <borut.razem AT siol.net>
9999 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
10000 the path of bin directory, so that PATH is the only env. variable, which has to be set
10001 in case of standard installation.

11018 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11019 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11028 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11029 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11031 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11033 * in /sdcc/as/mcs51/ changed these files in order to create an
11034 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11035 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11036 following files to include the previous two files: aslink.dsp,
11037 Makefile.aslink, Makefile.bcc, and Makefile.in.
11039 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11040 .adb instead of .cdb
11042 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11044 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11045 value from option --iram-size.
11047 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11049 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11052 2002-09-18 <wiml AT hhhh.org>
11054 * SDCClrange.h: exposed setFromRange() and setToRange()
11055 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11056 packRegsForAccUse() (bug 542397)
11057 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11058 multiple times and emitting the fetch operations more than once
11059 added aopGetUsesAcc() function to allow binary operators to
11060 fetch their operands in the correct order; made genMinus() emit
11061 compact code for X = LITERAL - Y
11063 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11064 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11065 sprintf() in line 1267.
11067 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11068 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11071 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11072 Changes to aslink (All the changes are marked with 'JCF'):
11074 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11077 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11078 area BSEG. Also moves, if possible, the DATA area down into the internal
11079 ram so more space is available.
11081 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11084 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11085 not bytes. Function summary() which creates a memory usage summary
11086 file with extension .mem. Reports of overlaping stack and small stack
11087 size. If the space for the stack is less than 16 bytes aslink trows a
11090 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11091 the 8051. Option 'y' for memory summary output file.
11093 Changes to sdcc (All the changes are marked with 'JCF'):
11095 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11097 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11098 overlaying area for it (uses RegBankUsed[4]).
11100 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11101 bank zero as used by default. By default aslink locates the stack
11102 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11103 the creation of the .mem file. Delegates the allocation of data area
11104 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11105 the begining of the stack area to aslink.
11107 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11108 glue() in SDCCglue.c creates an area for it.
11110 2002-09-03 Borut Razem <borut.razem AT siol.net>
11111 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11112 sdcc/src/pic/glue.c:
11113 introduced atexit() handler for teporay files removal in case of
11114 errors, assertions, ...
11116 2002-08-29 Borut Razem <borut.razem AT siol.net>
11117 * sdcc/support/cpp2/auto-host_vc_in.h:
11118 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11119 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11120 Maybe there is a similar problem with BORLANDC? It should be checked!
11122 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11123 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11124 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11125 was not executed, and the compiler (cl) launched a warning:
11126 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11128 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11129 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11131 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11132 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11134 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11135 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11136 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11137 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11138 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11139 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11140 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11141 - added Release configuration in VS projects
11142 - review of compiler an linker options
11143 - VC .exe files are generated in bin_vc directory, not to interfere
11144 with binaries generated from other projects (cygwin, mingw, bcc ...)
11146 * sdcc/src/yacc.dsp: added
11148 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11149 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11150 and insert the version number definitions from .version
11152 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11154 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11155 added - genarate auto-host.h using auto-host_vc_in.h as template
11158 removed from CVS, generated automatically
11160 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11161 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11163 2002-08-11 Borut Razem <borut.razem AT siol.net>
11164 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11166 2002-08-10 Borut Razem <borut.razem AT siol.net>
11167 * src/SDCCmain.c (main):
11168 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11169 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11170 The consequence was that some temporary files were not removed.
11173 unification of code in functions tempfilename() and tempfile():
11174 function tempnam() is defined in Visual Studio 6.0 and .NET
11176 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11178 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11179 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11180 - removed compiler command line option /WX: Treats all warnings as errors
11181 - update a list of source files, included into the project
11183 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11184 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11185 changed project type to Generic Project so that can be correcly converted to VS.NET project

11194 added return 0 statements after assert() to make compiler happy
11196 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11197 added newline in the def file to keep MSC compiler satisfied
11199 * sdcc/src/z80/gen.c:
11200 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11201 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11202 - solved MSC error in function aopDump()
11204 * sdcc_vc.h: define PREFIX as "\\sdcc"

11382 Previous fix was not good. basic blocks that have "break" or "return" are
11383 not really partof a loop , but live ranges used in these blocks should
