1133 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1135 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1136 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1138 One basic decision: e.g. src/clean.mk includes further files. In order
1139 to make this work there are two solutions:
1140 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1141 run configure on them. This way they can use
1142 'include $(srcdir)/port-clean.mk'
1143 - always include clean.mk by the Makefile at the same level. To avoid
1144 that `make clean` tries to include and build Makefile.dep the
1145 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1146 implemented, because now even `make uninstall` doesn't create
1147 Makefile.in. clean.mk could be eliminated by pasting it in
1150 * debugger/mcs51/Makefile.in: build own objects from library sources
1151 (SLIB, SDCC) in current directory
1153 * configure, configure.in: renamed --disable-device-lib-build in
1154 --disable-device-lib; added --enable-doc, the required tools are
1155 searched by configure; added result message; the toolchain for the
1156 belonging ports are now only built, if the port is enabled.
1158 * support/regression/*: all output is written in directory gen, because
1159 the fwk and ports directories don't livet in the build tree using vpath
1161 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1162 --disable-device-lib, added --enable-doc, added section VPATH
1164 * sim/ucsim/configure.in,
1165 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1166 z80 are enabled by default
1168 2006-04-24 Raphael Neider <rneider AT web.de>
1170 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1171 to config word, "pic14_"-prefixed some extern functions
1172 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1173 config word has been found
1174 * src/pic/device.h: added prototypes
1175 * src/pic/pcode.c: added "pic14_"-prefix where needed
1176 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1178 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1181 (pic14createInterruptVect): moved generating __config directives away

1193 (pCodeRegOptimizeRegUsage): fixed typo in comment

1197 * device/examples/main8051.c: deleted - it was removed from CVS

1416 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1418 * src/mcs51/gen.c (genCall): fixed bug 1457608
1420 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1425 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1427 * src/SDCCpeeph.c (operandsLiteral): new, added,

1439 implemented patch 1120823 Thanks to Willy De la Court (normal
1440 interrupts need an interrupt number now if they are made critical),
1441 and enabled nesting of critical functions though not for gbz80
1442 (genCritical, genEndCritical): added functions
1443 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1444 * src/z80/mappings.i: added "ei" to all mappings

1453 2006-03-16 Raphael Neider <rneider AT web.de>
1455 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1456 the left operand is shorter than the result (c* = lit-c* + int),
1458 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1461 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1463 * src/.version: increased version number to 2.5.5
1464 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1465 linking is done manually in pic16 port's _linkEdit,
1466 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1467 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1468 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1469 allocate asmop as AOP_ACC,
1470 (aopForRemat): added parameter 'bool result' in function declaration,
1471 (pic16_aopGet): return AOP_ACC when accessing WREG,
1472 (pic16_popGetTempReg): minor modification,
1473 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1474 'pic16_allocWithIdx',

1476 calling function in absolute addresses,
1477 (genAssign): take into account AOP_ACC asmop,

1481 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1483 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1484 call to allocReg, not by manually allocating a new one,
1485 (pic16_assignRegisters): now before going through the register
1486 allocating functions mark all registers as free. This eliminates some
1487 side effects resulting from peephole parser done earlier in the backbone
1489 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1491 * src/SDCCicode.c (geniCodeLogic),

1511 (aopForSym, aopOp): increment asmop.allocated if reused,
1512 (freeAsmop): decrement asmop.allocated and check for zero instead of
1514 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1515 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1516 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1539 2006-03-06 Borut Razem <borut.razem AT siol.net>
1541 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1542 made the linker quiet
1544 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1546 * src/pic16/gen.c (genPcall): fixed bug #1443644
1547 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1548 which dumps before the function entry point a data byte which represents
1549 the number of the local variables used by the specified function, added
1550 'xinst' for initial support for Extended Instruction Support,
1551 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1552 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1553 port->fun_prefix anymore (may change later),
1554 (genFunction, genEndFunction): do not store/restore local registers for
1555 _main (this should take care the --main-return command line option in
1557 (genOr): removed some legacy pic-port instructions,
1558 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1559 performing operations with SFR's causes data to be written more than
1560 once to each SFR. Perhaps SFRs should be handled in special cases...
1561 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1563 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1564 into account for stack starting position,
1565 (struct OPTIONS pic16_optionsTable): added command line argument
1566 --extended or -y for Extended Instruction Support,
1567 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1568 (deassignLRs): *** perhaps the most important change, old 'for' code
1569 (commented out for reference), didn't account for some registers which
1570 were left marked 'not free' after a pointer operation. The change
1571 reduces register usage a lot in some cases
1573 2006-03-04 Borut Razem <borut.razem AT siol.net>
1575 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3852 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3853 reserved identifier "__data".
3855 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3901 2005-03-20 Borut Razem <borut.razem AT siol.net>
3903 * support/scripts/inc2h.pl: WIN32 port

3909 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3911 * device/include/stdint.h: added
3912 * device/lib/abs.c: added
3913 * device/lib/labs.c: added
3914 * device/include/stdlib.h: added abs() and labs() prototypes

3929 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3931 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3933 * device/lib/printf_large.c: removed inline assembly for portability and
3934 readability. Use printf_fast if speed or size are more important.
3935 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3936 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3938 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3940 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3941 prevent compiler warning
3943 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3945 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3946 moved to level 0 and declared as static. Also they are explicit
3947 placed in access bank. This was necessery because some times they
3948 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3949 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3950 optimizations. Currently only compare to unsigned char is implemented,
3951 * src/pic16/gen.c: added fReturnIdx array,
3952 * (struct resolvedIfx) is moved to gen.h and made public,
3953 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3954 * (aopForSym): added an optimization to directly store in stack of
3955 the operand of a SEND iCode,
3956 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3957 but as registers instead (AOP_REG) using the fReturnIdx array,
3958 * (pic16_freeAsmop): remove the freed register from the
3959 _G.sregsAlloc field,
3960 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3961 a compare of 'WREG',
3962 * (pic16_popGetTempRegCond): changed function prototype, now
3963 function takes also a bitVector argument v which holds the current
3964 set of registers that are allocated for stack access by aopForSym,
3965 registers allocated in aopForSym for accessing stack symbols are not
3966 any more part of the functions usedRegs field,
3967 * (genCall): some times aopOp is called for a stack variable to be
3968 send, aopForSym might perform the push, if this is true make sure
3969 that genCall doesn't push the variable twice by testing _G.resDirect,
3970 * (genFunction): changed testing for unspecified interrupt number
3971 from 256 to INTNO_UNSPEC,
3972 * modified selection scheme of frame pointer generation. Previously
3973 if function did use local registers a frame pointer was generated,
3974 now a frame pointer is generated only if function has arguments
3975 (that need PLUSW2 register access), or has stack arguments, or the
3976 compiler is not instructed to omit the frame pointer,
3977 * (genEndFunction): before restoring local registers that were saved
3978 in the function preamble, also restore the registers that *might*
3979 have been allocated for stack access,
3980 * (genRet): removed some old comments,
3981 * (genCmp, the active (RN's) version): added a call to the
3982 pic16_genCmp_special function to perform the compare with a more
3983 robust and optimized way,
3984 * (genInline): a feature has been added in inline code generation,
3985 which allows a wildcard variable substitution when writing inline
3986 assembly. Code is incomplete and experimental therefore undocumented,
3987 * (genCast): changed order of aopOp for result and right to allow
3988 aopForSym to directly load the result if possible,
3989 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3990 perform an optimized compare on some selected special occasions,
3991 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3992 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3993 generate an IVT any more,
3994 * src/pic16/main.c (pic16_optionsTable): added command line option
3996 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3997 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3999 * src/pic16/NOTES: Raphael Neider added in list of active developers
4000 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4001 jumptable_end to prevent bug #,
4002 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4003 inCond and outCond fields,
4004 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4005 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4006 turn off register spilling,
4007 * (packRegsForOneUse): synced with other ports' versions although it
4008 is not used currently,
4009 * (pic16_packRegisters): added an optimization while reading
4010 structure bitfields, some registers may be saved (malloc code is
4011 decreased by 80 bytes)
4013 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4015 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4016 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4017 this can be optimized more?
4019 2005-03-10 Raphael Neider <rneider AT web.de>
4021 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4022 genNearPointerGet): (hopefully) fixed access to bitfields via
4023 pointers (p->bitN = x; and x = p->bitN; failed)
4025 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4213 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4214 this might fix SIGSEGVs on MinGW...

4657 Adding support for replacing ljmps with sjmps in jumptables
4658 generated for switch statements. For now you need to set the
4659 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4660 Now 4 algorithms for mcs51 jumptable generation are used:
4661 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4662 addresses loaded pc-relative for up to 112 cases and stack-pushing
4663 target addresses loaded with offset from dptr for up to 256 cases.

4693 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4695 * added libc directory. The current version of LibC contains string
4696 functions, ctype functions and macros and some functions of the
4697 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4698 be extensively tested in the future. Standard disclaimer here.
4699 Library is not automatically build yet. But one can build it by
4700 invoking 'make' inside the libc directory.
4701 * added ADC library under libio. Preliminary version yet.

4710 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4711 * (pic16_storeForReturn): optimized return of 0,
4712 * (genCmp): experimental code for new genCmp which uses PIC18's
4713 special compare&skip instructions. Initial tests fail some times
4714 with variables grater than 1 byte in size, so new code is disabled,
4715 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4717 * (genCast): began a fix to optimize the casting of a bit to another
4718 bit, now assigning a bitfield to another bitfield will fail, sorry,

4723 bits with offset (case PO_GPR_BIT),
4724 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4726 * (isBankInstruction): modified to return 0 for no banking instruction,
4727 and 1 for banking instruction,
4728 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,

7741 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7743 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7744 loaded with the linker search paths (-L arguments) and the libraries
7745 to be linked with the current source (-l arguments). Changes
7746 currently will affect only the pic16 port.
7747 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7748 include path the port specific paths and port specific libraries,
7749 * gplink command now contains the $3 argument,
7750 * src/pic16/device.h,
7751 * src/pic16/device.c,: structure PIC_device is made public and
7752 renamed to PIC16_device, the same for variable Pics which is renamed

7767 Documenting changes from previous commits.
7768 * configure.in (version 1.56),
7769 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7770 when generating output files to configure the pic16 library,
7771 but now I've commented it out, since gputils aren't installed in the
7772 SF compile farm, so library won't compile
7774 * device/lib/Makefile.in (version 1.56): initially I've added in
7775 target 'all' the prerequestive 'model-pic16' so it compiled the
7776 pic16 library, but now I've commented it out for the same reasons
7778 * added targets 'model-pic16' and 'objects-pic16' to compile the
7780 * added target 'port-specific-objects-pic16' to handle the
7781 generated libraries and copy them into the build/ directory
7782 * added target 'clean-intermediate-pic16' to clean intermediate
7783 files into pic16 directory
7784 * in target 'installdirs' added line to create directory pic16 in
7785 the installation path
7787 * device/include/Makefile.in (version 1.11): in target 'install'
7788 added lines to copy all header files to installation path,
7789 * in target 'installdirs' added line create directory for pic16
7790 headers in the installation path

7805 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7806 option so that it actually works. Made it specific to the z80, since
7807 the gbz80 doesn't have these kinds of I/O ports.
7809 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7811 * device/include/z180.h,

7840 weren't marked as being in the access bank,
7842 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7844 Added portion of GNU PIC Library under the directory
7845 device/include/pic16 and device/lib/pic16. These files
7846 contain the declarations of SFRs for the PIC18Fxx2 devices.
7847 The directory is initialized via configure from toplevel.
7849 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

7877 all over. Telling LaTeX to be less strict with word spacing
7878 to better keep the right margin. Changed some notes about
7879 maintainance of the ports in section 3.2.1 - is it OK like this?
7881 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7921 * src/pic16/peeph.def: all peepholes with movff are commented out,
7922 because there is a problem in the pcode peep optimizer,
7923 * src/pic16/ralloc.c: the register allocator can now reuse local

8000 2004-01-07 Borut Razem <borut.razem AT siol.net>
8002 * support/scripts/sdcc.nsi: update PATH
8003 * support/scripts/sdcc.ico: craeted

8016 include information about variables allocated to the overlay
8019 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8021 * as/mcs51/lkmain.c: Help about -Y option

8033 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8035 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8036 (default behaviour).
8038 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8040 A python script to validate compiler diagnostic messages. It can be
8041 used to verify that sdcc complains about bad c source code and
8042 gives a good location of the error.
8043 * support/valdiag/Makefile,
8044 * support/valdiag/valdiag.py,
8045 * support/valdiag/tests/*
8047 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8060 * src/common.h: added ifndef/define/endif macros
8061 around the header file.
8062 Bug reported from Jesus Calvino-Fraga
8064 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8066 * sdcc.spec: updated
8067 * device/include/Makefile.in: don't install CVS directories
8068 * device/lib/Makefile.in: added removal of CVS directories after install
8069 * doc/Makefile: fixed install, added local_icons
8070 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8071 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8072 * src/ds390/gen.c (genRightShift): fixed bug #870788
8073 * src/SDCCast.c (decorateType): fixed bug #870781
8075 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8077 PIC16 port related changes:
8078 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8079 added variable stackPos,
8081 * gen.c: genCall, assignResultValue: added support for
8082 pushing/retrieving function parameters to/from stack,
8083 genFunction,genEndFunction: setup stack frame for the
8085 genAddrOf: will be changed according to bug 863624
8087 * added files genutils.c and genutils.h which contain gen*
8088 debugged and optimised functions extracted from gen.c
8090 * glue.c: added variable 'externs' which holds extern symbols,
8091 pic16emitRegularMap: is modified to properly handle relocatable
8092 symbols under the new scheme,
8093 pic16createInterruptVect: is modified
8094 pic16printPublics: is modified to emit 'global' assembler directives,
8095 added pic16_printExterns to print extern symbols,
8096 pic16glue: initializes stack/frame pointer in the beginning of
8097 the assembly output. Temporary hack, will be corrected later,
8098 because gplink yet does not support stack and SDCC does not
8099 yet support a type of crt0.o object to create the final binary.
8101 * Removed many lines that contain 8051 legacy code.
8102 * The code is finally placed under a 'code' directive.
8103 * Added port specific options.
8105 * _process_pragma: simplified since now we do not need *special*
8106 include file to define SFR registers. But a separate header
8107 will be needed. This will be developed later.
8108 * _pic16_parseOptions: added, parses port specific options:
8109 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8110 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8111 --preplace-udata-with=
8113 * _pic16_setDefaultOptions: modified to initialize section names,
8114 but hack is temporarly out of order since it needs improvement.
8115 * _pic16_genAssemblerPreamble: configuration words are emitted by
8116 their address instead of their name. This part is incomplete and
8117 supports only the 18Fxx2 devices. Other devices will emit an error
8118 during assembly since they do not contain the same set of config
8120 * _pic16_genIVT: is modified,
8122 * pcode.c: added definitions for some hardware registers that are needed
8124 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8125 All PCI entries are updated. Now LFSR is supported.
8126 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8127 * added pic16_newpCodeOpLit2 to support instructions with
8128 two literal arguments
8129 * pic16_pCode2str: corrected code that emits assembler instructions
8130 with two literal operands and those that have an access bit modifier
8131 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8132 this fixes a bug which caused some labels to be lost, when an
8133 assembler directive was added, i.e. banksel,
8134 * pic16_FixRegisterBanking: improved logic that causes the insertion
8136 * InlineFunction: functions that are called once, are not any more
8137 inlined. This can be a port option in the future,
8139 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8141 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8142 hold the corresponding uninitialized symbols,
8143 * pic16_allocProcessorRegister: registers have explicit marked the
8145 * pic16_allocInternalRegister: registers are explicit marked as
8147 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8148 processing list, so bit registers were lost,
8151 * ralloc.h: added field 'accessBank' and original symbol operand
8152 in register definition,
8153 * removed the field isMapped from register definition,
8155 ** Several functions have been removed from various sources:
8156 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8157 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8158 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8159 pic16_assignRelocatableRegisters
8161 ** others have been introduced:
8162 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8163 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8165 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8167 * support/scripts/inc2h.pl: changed definition of BIT_AT
8168 to emit 'sbit at' instead of 'bit at'. This was a request.
8170 PIC16 port related preliminary changes:
8171 * gen.c: prefixed function popRegFromString with
8172 pic16_ and all references to it corrected
8173 * pcode.c: all pic16_pc_* hardware registers prefixed
8174 with underscore (_),
8175 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8176 * ralloc.c: newReg(): when register is REG_SFR then
8177 set address to rIdx,
8178 pic16_allocProcessorRegister(): marks register wasUsed=0
8179 pic16_writeUsedRegs(): added a call to assign processor
8180 registers via pic16_assignFixedRegisters
8182 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8184 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8185 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8186 variables in unused register banks. Also the SSEG is placed
8187 wherever there is enough space for it, and IDATA can be anywhere
8188 in internal RAM. For now compile using -Wl-Y[stack_size].
8189 The mem file is different for this option as well, since it
8190 makes no sense of talking about DSEG lenght.
8192 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8194 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8195 in certain cases, e.g. when ROM assignment, patch provided
8196 from Albert den Haan.
8198 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8341 * src/mcs51/peephole.def,
8342 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
8343 (allows non-interrupt and interrupt code to safely compete for a resource
8344 without the non-interrupt code having to disable interrupts)
8346 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8348 * src/SDCCicode.c (geniCodeAdd),

8441 it breaks with bitfields, extern declarations, and gcse analysis.
8442 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8443 could be assigned through a pointer, so don't complain.

9221 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9222 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9223 type for bits was changed. It resulted in bit variables becoming
9224 global, which is not permitted in PIC 14 assembly output.

9241 A few small changes that speed up the peephole optimizer.
9245 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9247 Try to make the peephole optimizer smarter by maintaining
9248 an association between the assembly source code and the
9249 iCodes that originated them. Put this information to use
9250 with a new peephole rule condition "notVolatile" so that
9251 the rules can be aggressive yet still safe.
9256 * src/mcs51/peeph.def
9258 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9262 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9263 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9264 if the left or right operand symbols have the accuse flag set.
9266 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9268 Changed the type of the result of the ! (NOT) operator to char;
9269 previously it returned the same type as the source. This allows
9270 us to eliminate all the genFloatNot functions (all of its target
9271 implementations were very buggy) since !float can use the same
9274 * src/SDCCicode.c (ast2iCode): ! returns char

9283 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9284 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9285 during interrupts. Ensure WSAVE is located at a shared bank address.
9286 2. Fixed page selection in some places
9287 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9288 the registers name strings.
9289 4. Fixed "signed / unsigned compare" compiler warnings.
9290 5. The PIC port manages its own allocation of the general purpose
9291 registers, but makes no attempt to reuse them. As a result when
9292 compiling it soon runs out of general purpose registers. Some
9293 additional code was added to the files pcode.c and device.c to walk
9294 through the function call tree and rename the registers so that they
9304 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9305 genPlus() & genMinus() when the result is the same as left or right

9311 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9313 Made bitfield a distinct type from bit so that bitfields
9314 convert as per ANSI C and bits retain their traditional
9315 boolean style behaviour. Implemented bitfield support in
9323 * src/ds390/gen.c: bit v bitfield split
9324 * src/z80/gen.c: New support for bitfields
9325 * support/regression/tests/bitfields.c: reenabled z80,
9328 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9330 Rules 246.x, 247.x relate to bitfields, the others speed up
9331 access to xdata mapped I/O devices.
9333 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9335 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9337 Cleaned up genPackBits and genUnpackBits and added two helper
9338 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9339 for literal assignments in genPackBits (thanks to Frieder for
9345 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9347 Fixed bug #748310 (pointer to function type mishandled when the
9348 function name is omitted). Also fixed a SIGSEGV when a function
9349 attribute (reentrant, etc) is used on a non-function or on a

9380 omitted, the function will not automatically be given an entry
9381 in the interrupt vector table (similar to #pragma NOIV, but

9919 from initialization assignment, since now it is a set,
9920 parseCmdLine uses setParseWithComma for linkOptions, in
9921 linkEdit() linkOptions are accessed with new function indexSet()
9922 which returns the i'th item of a set variable. See SDCCset.c, in
9923 linkEdit() when calling buildCmdLine(), added linkOptions as
9924 last argument. Now users can pass arguments to gplink via the
9925 -Wl option, main() uses pic16glue() to glue up pic16 programs

9939 gpasm complaining and test the linkage with gplink, _linkCmd and
9940 _asmCmd changed to be more gplink and gpasm friendly
9941 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9942 produced an error when parsed, peep rule 12 is added to utilize
9943 movff, but it is commented out since the pCode does not support
9944 yet a command with 2 address arguments

11007 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11009 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11011 * in /sdcc/as/mcs51/ changed these files in order to create an
11012 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11013 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11014 following files to include the previous two files: aslink.dsp,
11015 Makefile.aslink, Makefile.bcc, and Makefile.in.
11017 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11018 .adb instead of .cdb
11020 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11022 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11023 value from option --iram-size.
11025 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11027 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11030 2002-09-18 <wiml AT hhhh.org>
11032 * SDCClrange.h: exposed setFromRange() and setToRange()
11033 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11034 packRegsForAccUse() (bug 542397)
11035 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11036 multiple times and emitting the fetch operations more than once
11037 added aopGetUsesAcc() function to allow binary operators to
11038 fetch their operands in the correct order; made genMinus() emit
11039 compact code for X = LITERAL - Y
11041 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11042 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11043 sprintf() in line 1267.
11045 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11046 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11049 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11050 Changes to aslink (All the changes are marked with 'JCF'):
11052 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11055 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11056 area BSEG. Also moves, if possible, the DATA area down into the internal
11057 ram so more space is available.
11059 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11062 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11063 not bytes. Function summary() which creates a memory usage summary
11064 file with extension .mem. Reports of overlaping stack and small stack
11065 size. If the space for the stack is less than 16 bytes aslink trows a
11068 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11069 the 8051. Option 'y' for memory summary output file.
11071 Changes to sdcc (All the changes are marked with 'JCF'):
11073 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11075 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11076 overlaying area for it (uses RegBankUsed[4]).
11078 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11079 bank zero as used by default. By default aslink locates the stack
11080 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11081 the creation of the .mem file. Delegates the allocation of data area
11082 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11083 the begining of the stack area to aslink.
11085 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11086 glue() in SDCCglue.c creates an area for it.
11088 2002-09-03 Borut Razem <borut.razem AT siol.net>
11089 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11090 sdcc/src/pic/glue.c:
11091 introduced atexit() handler for teporay files removal in case of
11092 errors, assertions, ...
11094 2002-08-29 Borut Razem <borut.razem AT siol.net>
11095 * sdcc/support/cpp2/auto-host_vc_in.h:
11096 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11097 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11098 Maybe there is a similar problem with BORLANDC? It should be checked!
11100 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11101 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11102 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11103 was not executed, and the compiler (cl) launched a warning:
11104 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11106 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11107 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11109 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11110 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects

11117 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11118 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11119 - added Release configuration in VS projects
11120 - review of compiler an linker options
11121 - VC .exe files are generated in bin_vc directory, not to interfere
11122 with binaries generated from other projects (cygwin, mingw, bcc ...)
11124 * sdcc/src/yacc.dsp: added
11126 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11127 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11128 and insert the version number definitions from .version

11132 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11133 added - genarate auto-host.h using auto-host_vc_in.h as template
11136 removed from CVS, generated automatically
11138 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11139 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11141 2002-08-11 Borut Razem <borut.razem AT siol.net>
11142 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11144 2002-08-10 Borut Razem <borut.razem AT siol.net>
11145 * src/SDCCmain.c (main):
11146 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11147 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11148 The consequence was that some temporary files were not removed.
11151 unification of code in functions tempfilename() and tempfile():
11152 function tempnam() is defined in Visual Studio 6.0 and .NET
11154 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11156 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11157 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11158 - removed compiler command line option /WX: Treats all warnings as errors
11159 - update a list of source files, included into the project
11161 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11162 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11163 changed project type to Generic Project so that can be correcly converted to VS.NET project
11165 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11167 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11169 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11171 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:

11178 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11179 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11180 - solved MSC error in function aopDump()

11360 Previous fix was not good. basic blocks that have "break" or "return" are
11361 not really partof a loop , but live ranges used in these blocks should
