1149 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1151 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1152 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1154 One basic decision: e.g. src/clean.mk includes further files. In order
1155 to make this work there are two solutions:
1156 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1157 run configure on them. This way they can use
1158 'include $(srcdir)/port-clean.mk'
1159 - always include clean.mk by the Makefile at the same level. To avoid
1160 that `make clean` tries to include and build Makefile.dep the
1161 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1162 implemented, because now even `make uninstall` doesn't create
1163 Makefile.in. clean.mk could be eliminated by pasting it in
1166 * debugger/mcs51/Makefile.in: build own objects from library sources
1167 (SLIB, SDCC) in current directory
1169 * configure, configure.in: renamed --disable-device-lib-build in
1170 --disable-device-lib; added --enable-doc, the required tools are
1171 searched by configure; added result message; the toolchain for the
1172 belonging ports are now only built, if the port is enabled.
1174 * support/regression/*: all output is written in directory gen, because
1175 the fwk and ports directories don't livet in the build tree using vpath
1177 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1178 --disable-device-lib, added --enable-doc, added section VPATH
1180 * sim/ucsim/configure.in,
1181 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1182 z80 are enabled by default
1184 2006-04-24 Raphael Neider <rneider AT web.de>
1186 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1187 to config word, "pic14_"-prefixed some extern functions
1188 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1189 config word has been found
1190 * src/pic/device.h: added prototypes
1191 * src/pic/pcode.c: added "pic14_"-prefix where needed
1192 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1194 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1197 (pic14createInterruptVect): moved generating __config directives away

1208 fixes #1469504 and #1474602,
1209 (pCodeRegOptimizeRegUsage): fixed typo in comment

1455 implemented patch 1120823 Thanks to Willy De la Court (normal
1456 interrupts need an interrupt number now if they are made critical),
1457 and enabled nesting of critical functions though not for gbz80
1458 (genCritical, genEndCritical): added functions
1459 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1460 * src/z80/mappings.i: added "ei" to all mappings

1472 the left operand is shorter than the result (c* = lit-c* + int),
1474 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1477 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1479 * src/.version: increased version number to 2.5.5
1480 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1481 linking is done manually in pic16 port's _linkEdit,
1482 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1483 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1484 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1485 allocate asmop as AOP_ACC,
1486 (aopForRemat): added parameter 'bool result' in function declaration,
1487 (pic16_aopGet): return AOP_ACC when accessing WREG,
1488 (pic16_popGetTempReg): minor modification,

1499 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1500 call to allocReg, not by manually allocating a new one,
1501 (pic16_assignRegisters): now before going through the register
1502 allocating functions mark all registers as free. This eliminates some
1503 side effects resulting from peephole parser done earlier in the backbone
1505 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1555 2006-03-06 Borut Razem <borut.razem AT siol.net>
1557 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1558 made the linker quiet

1563 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1564 which dumps before the function entry point a data byte which represents
1565 the number of the local variables used by the specified function, added
1566 'xinst' for initial support for Extended Instruction Support,
1567 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1568 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1569 port->fun_prefix anymore (may change later),
1570 (genFunction, genEndFunction): do not store/restore local registers for
1571 _main (this should take care the --main-return command line option in
1573 (genOr): removed some legacy pic-port instructions,
1574 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1575 performing operations with SFR's causes data to be written more than
1576 once to each SFR. Perhaps SFRs should be handled in special cases...
1577 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1579 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1580 into account for stack starting position,

1582 --extended or -y for Extended Instruction Support,
1583 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1584 (deassignLRs): *** perhaps the most important change, old 'for' code
1585 (commented out for reference), didn't account for some registers which
1586 were left marked 'not free' after a pointer operation. The change
1587 reduces register usage a lot in some cases

3848 2005-03-26 Raphael Neider <rneider AT web.de>
3850 * src/pic16/gen.c (genSkipc): fixed semantics (execute branch
3851 if condition == CARRY)
3852 * (genCmp): adapted to new genSkipc semantics
3853 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
3854 on rIfx (genCmp was broken)
3856 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3858 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3859 * src/z80/main.c (_keywords[]),
3860 * src/SDCCglobal.h (struct options),
3862 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3863 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3864 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3865 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3866 always available in leading double underscore form. The C99 support is
3867 mostly missing, but it's a start.
3868 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3869 reserved identifier "__data".
3871 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3873 * src/mcs51/peeph.def: fixed bug 1170013

3881 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
3884 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3886 * src/port.h (struct PORT),
3887 * src/avr/ralloc.c (avr_assignRegisters),
3889 * src/ds390/ralloc.c (ds390_assignRegisters),
3891 * src/hc08/ralloc.c (hc08_assignRegisters),

3913 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
3914 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3915 immedDom() returning wrong block; probably fixes bug #1160833)
3917 2005-03-20 Borut Razem <borut.razem AT siol.net>
3919 * support/scripts/inc2h.pl: WIN32 port
3921 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3923 * device/lib/makefile.in: added abs.c and labs.c
3925 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3927 * device/include/stdint.h: added
3928 * device/lib/abs.c: added
3929 * device/lib/labs.c: added
3930 * device/include/stdlib.h: added abs() and labs() prototypes
3931 * device/lib/libsdcc.lib: added abs and labs
3932 * device/include/float.h,

3945 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3947 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3949 * device/lib/printf_large.c: removed inline assembly for portability and
3950 readability. Use printf_fast if speed or size are more important.
3951 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3952 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3954 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3956 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3957 prevent compiler warning
3959 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3961 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3962 moved to level 0 and declared as static. Also they are explicit
3963 placed in access bank. This was necessery because some times they
3964 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3965 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3966 optimizations. Currently only compare to unsigned char is implemented,
3967 * src/pic16/gen.c: added fReturnIdx array,
3968 * (struct resolvedIfx) is moved to gen.h and made public,
3969 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3970 * (aopForSym): added an optimization to directly store in stack of
3971 the operand of a SEND iCode,
3972 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3973 but as registers instead (AOP_REG) using the fReturnIdx array,
3974 * (pic16_freeAsmop): remove the freed register from the
3975 _G.sregsAlloc field,
3976 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3977 a compare of 'WREG',
3978 * (pic16_popGetTempRegCond): changed function prototype, now
3979 function takes also a bitVector argument v which holds the current
3980 set of registers that are allocated for stack access by aopForSym,
3981 registers allocated in aopForSym for accessing stack symbols are not
3982 any more part of the functions usedRegs field,
3983 * (genCall): some times aopOp is called for a stack variable to be
3984 send, aopForSym might perform the push, if this is true make sure
3985 that genCall doesn't push the variable twice by testing _G.resDirect,
3986 * (genFunction): changed testing for unspecified interrupt number
3987 from 256 to INTNO_UNSPEC,
3988 * modified selection scheme of frame pointer generation. Previously
3989 if function did use local registers a frame pointer was generated,
3990 now a frame pointer is generated only if function has arguments
3991 (that need PLUSW2 register access), or has stack arguments, or the
3992 compiler is not instructed to omit the frame pointer,
3993 * (genEndFunction): before restoring local registers that were saved
3994 in the function preamble, also restore the registers that *might*
3995 have been allocated for stack access,
3996 * (genRet): removed some old comments,
3997 * (genCmp, the active (RN's) version): added a call to the
3998 pic16_genCmp_special function to perform the compare with a more
3999 robust and optimized way,
4000 * (genInline): a feature has been added in inline code generation,
4001 which allows a wildcard variable substitution when writing inline
4002 assembly. Code is incomplete and experimental therefore undocumented,
4003 * (genCast): changed order of aopOp for result and right to allow
4004 aopForSym to directly load the result if possible,
4005 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4006 perform an optimized compare on some selected special occasions,
4007 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4008 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4009 generate an IVT any more,
4010 * src/pic16/main.c (pic16_optionsTable): added command line option
4012 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4013 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4015 * src/pic16/NOTES: Raphael Neider added in list of active developers
4016 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4017 jumptable_end to prevent bug #,
4018 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4019 inCond and outCond fields,
4020 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4021 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4022 turn off register spilling,
4023 * (packRegsForOneUse): synced with other ports' versions although it
4024 is not used currently,
4025 * (pic16_packRegisters): added an optimization while reading
4026 structure bitfields, some registers may be saved (malloc code is
4027 decreased by 80 bytes)
4029 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4031 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4032 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4033 this can be optimized more?
4035 2005-03-10 Raphael Neider <rneider AT web.de>
4037 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4038 genNearPointerGet): (hopefully) fixed access to bitfields via
4039 pointers (p->bitN = x; and x = p->bitN; failed)
4041 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4228 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
4229 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4230 this might fix SIGSEGVs on MinGW...
4231 * src/SDCCopt.c (killDeadCode): restored original behaviour
4232 (volatile operands might get thrown away though)
4234 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

7757 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7759 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7760 loaded with the linker search paths (-L arguments) and the libraries
7761 to be linked with the current source (-l arguments). Changes
7762 currently will affect only the pic16 port.
7763 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7764 include path the port specific paths and port specific libraries,
7765 * gplink command now contains the $3 argument,
7766 * src/pic16/device.h,
7767 * src/pic16/device.c,: structure PIC_device is made public and
7768 renamed to PIC16_device, the same for variable Pics which is renamed

7783 Documenting changes from previous commits.
7784 * configure.in (version 1.56),
7785 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7786 when generating output files to configure the pic16 library,
7787 but now I've commented it out, since gputils aren't installed in the
7788 SF compile farm, so library won't compile
7790 * device/lib/Makefile.in (version 1.56): initially I've added in
7791 target 'all' the prerequestive 'model-pic16' so it compiled the
7792 pic16 library, but now I've commented it out for the same reasons
7794 * added targets 'model-pic16' and 'objects-pic16' to compile the
7796 * added target 'port-specific-objects-pic16' to handle the
7797 generated libraries and copy them into the build/ directory
7798 * added target 'clean-intermediate-pic16' to clean intermediate
7799 files into pic16 directory
7800 * in target 'installdirs' added line to create directory pic16 in
7801 the installation path
7803 * device/include/Makefile.in (version 1.11): in target 'install'
7804 added lines to copy all header files to installation path,
7805 * in target 'installdirs' added line create directory for pic16
7806 headers in the installation path

7821 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7822 option so that it actually works. Made it specific to the z80, since
7823 the gbz80 doesn't have these kinds of I/O ports.
7825 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7851 via literal number. The symbol is placed in the corresponding
7852 position of the data ram
7853 * (pic16_dump_section): relocatable and absolute uninitialized
7854 data are now emitted in sorted order to reduce section naming,
7855 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7856 weren't marked as being in the access bank,
7858 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>

7893 all over. Telling LaTeX to be less strict with word spacing
7894 to better keep the right margin. Changed some notes about
7895 maintainance of the ports in section 3.2.1 - is it OK like this?
7897 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7937 * src/pic16/peeph.def: all peepholes with movff are commented out,
7938 because there is a problem in the pcode peep optimizer,
7939 * src/pic16/ralloc.c: the register allocator can now reuse local

8016 2004-01-07 Borut Razem <borut.razem AT siol.net>
8018 * support/scripts/sdcc.nsi: update PATH
8019 * support/scripts/sdcc.ico: craeted

8032 include information about variables allocated to the overlay
8035 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8037 * as/mcs51/lkmain.c: Help about -Y option

8049 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8051 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8052 (default behaviour).
8054 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8056 A python script to validate compiler diagnostic messages. It can be
8057 used to verify that sdcc complains about bad c source code and
8058 gives a good location of the error.
8059 * support/valdiag/Makefile,
8060 * support/valdiag/valdiag.py,
8061 * support/valdiag/tests/*
8063 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8076 * src/common.h: added ifndef/define/endif macros
8077 around the header file.
8078 Bug reported from Jesus Calvino-Fraga
8080 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8082 * sdcc.spec: updated
8083 * device/include/Makefile.in: don't install CVS directories
8084 * device/lib/Makefile.in: added removal of CVS directories after install
8085 * doc/Makefile: fixed install, added local_icons
8086 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8087 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8088 * src/ds390/gen.c (genRightShift): fixed bug #870788
8089 * src/SDCCast.c (decorateType): fixed bug #870781
8091 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8093 PIC16 port related changes:
8094 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8095 added variable stackPos,
8097 * gen.c: genCall, assignResultValue: added support for
8098 pushing/retrieving function parameters to/from stack,
8099 genFunction,genEndFunction: setup stack frame for the
8101 genAddrOf: will be changed according to bug 863624
8103 * added files genutils.c and genutils.h which contain gen*
8104 debugged and optimised functions extracted from gen.c
8106 * glue.c: added variable 'externs' which holds extern symbols,
8107 pic16emitRegularMap: is modified to properly handle relocatable
8108 symbols under the new scheme,
8109 pic16createInterruptVect: is modified
8110 pic16printPublics: is modified to emit 'global' assembler directives,
8111 added pic16_printExterns to print extern symbols,
8112 pic16glue: initializes stack/frame pointer in the beginning of
8113 the assembly output. Temporary hack, will be corrected later,
8114 because gplink yet does not support stack and SDCC does not
8115 yet support a type of crt0.o object to create the final binary.
8117 * Removed many lines that contain 8051 legacy code.
8118 * The code is finally placed under a 'code' directive.
8119 * Added port specific options.
8121 * _process_pragma: simplified since now we do not need *special*
8122 include file to define SFR registers. But a separate header
8123 will be needed. This will be developed later.
8124 * _pic16_parseOptions: added, parses port specific options:
8125 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8126 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8127 --preplace-udata-with=
8129 * _pic16_setDefaultOptions: modified to initialize section names,
8130 but hack is temporarly out of order since it needs improvement.
8131 * _pic16_genAssemblerPreamble: configuration words are emitted by
8132 their address instead of their name. This part is incomplete and
8133 supports only the 18Fxx2 devices. Other devices will emit an error
8134 during assembly since they do not contain the same set of config
8136 * _pic16_genIVT: is modified,
8138 * pcode.c: added definitions for some hardware registers that are needed
8140 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8141 All PCI entries are updated. Now LFSR is supported.
8142 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8143 * added pic16_newpCodeOpLit2 to support instructions with
8144 two literal arguments
8145 * pic16_pCode2str: corrected code that emits assembler instructions
8146 with two literal operands and those that have an access bit modifier
8147 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8148 this fixes a bug which caused some labels to be lost, when an
8149 assembler directive was added, i.e. banksel,
8150 * pic16_FixRegisterBanking: improved logic that causes the insertion
8152 * InlineFunction: functions that are called once, are not any more
8153 inlined. This can be a port option in the future,
8155 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8157 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8158 hold the corresponding uninitialized symbols,
8159 * pic16_allocProcessorRegister: registers have explicit marked the
8161 * pic16_allocInternalRegister: registers are explicit marked as
8163 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8164 processing list, so bit registers were lost,
8167 * ralloc.h: added field 'accessBank' and original symbol operand
8168 in register definition,
8169 * removed the field isMapped from register definition,
8171 ** Several functions have been removed from various sources:
8172 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8173 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8174 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8175 pic16_assignRelocatableRegisters
8177 ** others have been introduced:
8178 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8179 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8181 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8183 * support/scripts/inc2h.pl: changed definition of BIT_AT
8184 to emit 'sbit at' instead of 'bit at'. This was a request.
8186 PIC16 port related preliminary changes:
8187 * gen.c: prefixed function popRegFromString with
8188 pic16_ and all references to it corrected
8189 * pcode.c: all pic16_pc_* hardware registers prefixed
8190 with underscore (_),
8191 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8192 * ralloc.c: newReg(): when register is REG_SFR then
8193 set address to rIdx,
8194 pic16_allocProcessorRegister(): marks register wasUsed=0
8195 pic16_writeUsedRegs(): added a call to assign processor
8196 registers via pic16_assignFixedRegisters
8198 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8200 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8201 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8202 variables in unused register banks. Also the SSEG is placed
8203 wherever there is enough space for it, and IDATA can be anywhere
8204 in internal RAM. For now compile using -Wl-Y[stack_size].
8205 The mem file is different for this option as well, since it
8206 makes no sense of talking about DSEG lenght.
8208 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8210 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8211 in certain cases, e.g. when ROM assignment, patch provided
8212 from Albert den Haan.
8214 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8384 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8386 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165

8457 it breaks with bitfields, extern declarations, and gcse analysis.
8458 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8459 could be assigned through a pointer, so don't complain.

9237 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9238 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9239 type for bits was changed. It resulted in bit variables becoming
9240 global, which is not permitted in PIC 14 assembly output.

9257 A few small changes that speed up the peephole optimizer.
9261 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9263 Try to make the peephole optimizer smarter by maintaining
9264 an association between the assembly source code and the
9265 iCodes that originated them. Put this information to use
9266 with a new peephole rule condition "notVolatile" so that
9267 the rules can be aggressive yet still safe.
9272 * src/mcs51/peeph.def
9274 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9278 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9279 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9280 if the left or right operand symbols have the accuse flag set.
9282 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9284 Changed the type of the result of the ! (NOT) operator to char;
9285 previously it returned the same type as the source. This allows
9286 us to eliminate all the genFloatNot functions (all of its target
9287 implementations were very buggy) since !float can use the same
9290 * src/SDCCicode.c (ast2iCode): ! returns char

9299 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9300 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9301 during interrupts. Ensure WSAVE is located at a shared bank address.
9302 2. Fixed page selection in some places
9303 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9304 the registers name strings.
9305 4. Fixed "signed / unsigned compare" compiler warnings.
9306 5. The PIC port manages its own allocation of the general purpose
9307 registers, but makes no attempt to reuse them. As a result when
9308 compiling it soon runs out of general purpose registers. Some
9309 additional code was added to the files pcode.c and device.c to walk
9310 through the function call tree and rename the registers so that they
9320 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9321 genPlus() & genMinus() when the result is the same as left or right

9327 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9329 Made bitfield a distinct type from bit so that bitfields
9330 convert as per ANSI C and bits retain their traditional
9331 boolean style behaviour. Implemented bitfield support in

9347 access to xdata mapped I/O devices.
9349 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9351 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9353 Cleaned up genPackBits and genUnpackBits and added two helper
9354 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9355 for literal assignments in genPackBits (thanks to Frieder for
9361 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9363 Fixed bug #748310 (pointer to function type mishandled when the
9364 function name is omitted). Also fixed a SIGSEGV when a function
9365 attribute (reentrant, etc) is used on a non-function or on a
9366 function but misplaced before the parameter list.

9395 Made the constant following the "interrupt" keyword optional. If
9396 omitted, the function will not automatically be given an entry
9397 in the interrupt vector table (similar to #pragma NOIV, but
9398 less syntacticly kludgy). The interrupt number is also now
9399 range checked. Also fixed a bug in the high order bit example

9420 unsigned, but are signed by default
9421 * src/SDCCval.c (constVal): rearranged
9422 * src/SDCCval.c (valMod): preliminary fix
9423 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9914 * doc/sdccman.lyx: fixed bug 739745
9915 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
9917 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9919 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9920 it can be defined with CFLAGS when running configure
9921 * src/SDCCmain.c: fixed compiling + linking with object files
9923 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9925 * configure.in: configure for pic16 port,
9926 added --disable-pic16-port
9927 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9928 * src/SDCCmain.c: linkOptions is changed to set *,
9929 added if/endif conditional macros to remove options help
9930 messages from optionsTable when a port is not configured, added
9931 support for the PIc16 port in the ports table, when executing
9932 the compiler with no port specified on command line, a default
9933 port is selected with the new macro DEFAULT_PORT which is
9934 defined in port.h, in setDefaultOptions() linkOptions is removed
9935 from initialization assignment, since now it is a set,
9936 parseCmdLine uses setParseWithComma for linkOptions, in
9937 linkEdit() linkOptions are accessed with new function indexSet()
9938 which returns the i'th item of a set variable. See SDCCset.c, in
9939 linkEdit() when calling buildCmdLine(), added linkOptions as
9940 last argument. Now users can pass arguments to gplink via the
9941 -Wl option, main() uses pic16glue() to glue up pic16 programs
9942 * src/SDCCpeeph.c: various changes to support pic16
9943 * src/SDCCset.c: added function void *indexSet(set *, int) to

9953 * src/pic16/glue.c: commented out some error producing lines
9954 * src/pic16/main.c: __config directives are commented out to stop
9955 gpasm complaining and test the linkage with gplink, _linkCmd and
9956 _asmCmd changed to be more gplink and gpasm friendly
9957 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9958 produced an error when parsed, peep rule 12 is added to utilize
9959 movff, but it is commented out since the pCode does not support
9960 yet a command with 2 address arguments
9962 2003-05-18 <johan AT balder>
9964 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9991 2003-05-11 Borut Razem <borut.razem AT siol.net>
9993 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9994 the path of bin directory, so that PATH is the only env. variable, which has to be set
9995 in case of standard installation.

11012 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11013 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11020 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11022 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11023 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11025 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11027 * in /sdcc/as/mcs51/ changed these files in order to create an
11028 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11029 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11030 following files to include the previous two files: aslink.dsp,
11031 Makefile.aslink, Makefile.bcc, and Makefile.in.
11033 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11034 .adb instead of .cdb
11036 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11038 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11039 value from option --iram-size.
11041 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11043 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11046 2002-09-18 <wiml AT hhhh.org>
11048 * SDCClrange.h: exposed setFromRange() and setToRange()
11049 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11050 packRegsForAccUse() (bug 542397)
11051 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11052 multiple times and emitting the fetch operations more than once
11053 added aopGetUsesAcc() function to allow binary operators to
11054 fetch their operands in the correct order; made genMinus() emit
11055 compact code for X = LITERAL - Y
11057 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11058 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11059 sprintf() in line 1267.
11061 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11062 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11065 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11066 Changes to aslink (All the changes are marked with 'JCF'):
11068 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11071 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11072 area BSEG. Also moves, if possible, the DATA area down into the internal
11073 ram so more space is available.
11075 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11078 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11079 not bytes. Function summary() which creates a memory usage summary
11080 file with extension .mem. Reports of overlaping stack and small stack
11081 size. If the space for the stack is less than 16 bytes aslink trows a
11084 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11085 the 8051. Option 'y' for memory summary output file.
11087 Changes to sdcc (All the changes are marked with 'JCF'):
11089 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11091 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11092 overlaying area for it (uses RegBankUsed[4]).
11094 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11095 bank zero as used by default. By default aslink locates the stack
11096 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11097 the creation of the .mem file. Delegates the allocation of data area
11098 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11099 the begining of the stack area to aslink.
11101 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11102 glue() in SDCCglue.c creates an area for it.
11104 2002-09-03 Borut Razem <borut.razem AT siol.net>
11105 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11106 sdcc/src/pic/glue.c:
11107 introduced atexit() handler for teporay files removal in case of
11108 errors, assertions, ...
11110 2002-08-29 Borut Razem <borut.razem AT siol.net>
11111 * sdcc/support/cpp2/auto-host_vc_in.h:
11112 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11113 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11114 Maybe there is a similar problem with BORLANDC? It should be checked!
11116 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11117 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11118 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11119 was not executed, and the compiler (cl) launched a warning:
11120 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11122 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11123 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11125 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11126 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11128 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11129 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11130 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11131 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11132 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11133 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11134 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11135 - added Release configuration in VS projects
11136 - review of compiler an linker options
11137 - VC .exe files are generated in bin_vc directory, not to interfere
11138 with binaries generated from other projects (cygwin, mingw, bcc ...)
11140 * sdcc/src/yacc.dsp: added
11142 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11143 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11144 and insert the version number definitions from .version
11146 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11148 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11149 added - genarate auto-host.h using auto-host_vc_in.h as template
11152 removed from CVS, generated automatically
11154 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11155 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11157 2002-08-11 Borut Razem <borut.razem AT siol.net>
11158 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11160 2002-08-10 Borut Razem <borut.razem AT siol.net>
11161 * src/SDCCmain.c (main):
11162 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11163 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11164 The consequence was that some temporary files were not removed.
11167 unification of code in functions tempfilename() and tempfile():
11168 function tempnam() is defined in Visual Studio 6.0 and .NET

11376 Previous fix was not good. basic blocks that have "break" or "return" are
11377 not really partof a loop , but live ranges used in these blocks should

12256 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
12258 2001-08-29 Michael Hope <michaelh AT juju.net.nz>
