1140 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1142 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1143 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1145 One basic decision: e.g. src/clean.mk includes further files. In order
1146 to make this work there are two solutions:
1147 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1148 run configure on them. This way they can use
1149 'include $(srcdir)/port-clean.mk'
1150 - always include clean.mk by the Makefile at the same level. To avoid
1151 that `make clean` tries to include and build Makefile.dep the
1152 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1153 implemented, because now even `make uninstall` doesn't create
1154 Makefile.in. clean.mk could be eliminated by pasting it in
1157 * debugger/mcs51/Makefile.in: build own objects from library sources
1158 (SLIB, SDCC) in current directory
1160 * configure, configure.in: renamed --disable-device-lib-build in
1161 --disable-device-lib; added --enable-doc, the required tools are
1162 searched by configure; added result message; the toolchain for the
1163 belonging ports are now only built, if the port is enabled.
1165 * support/regression/*: all output is written in directory gen, because
1166 the fwk and ports directories don't livet in the build tree using vpath
1168 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1169 --disable-device-lib, added --enable-doc, added section VPATH
1171 * sim/ucsim/configure.in,
1172 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1173 z80 are enabled by default
1175 2006-04-24 Raphael Neider <rneider AT web.de>
1177 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1178 to config word, "pic14_"-prefixed some extern functions
1179 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1180 config word has been found
1181 * src/pic/device.h: added prototypes
1182 * src/pic/pcode.c: added "pic14_"-prefix where needed
1183 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1185 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1188 (pic14createInterruptVect): moved generating __config directives away

1199 fixes #1469504 and #1474602,
1200 (pCodeRegOptimizeRegUsage): fixed typo in comment

1423 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1425 * src/mcs51/gen.c (genCall): fixed bug 1457608
1427 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1432 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1434 * src/SDCCpeeph.c (operandsLiteral): new, added,

1446 implemented patch 1120823 Thanks to Willy De la Court (normal
1447 interrupts need an interrupt number now if they are made critical),
1448 and enabled nesting of critical functions though not for gbz80
1449 (genCritical, genEndCritical): added functions
1450 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1451 * src/z80/mappings.i: added "ei" to all mappings

1460 2006-03-16 Raphael Neider <rneider AT web.de>
1462 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1463 the left operand is shorter than the result (c* = lit-c* + int),
1465 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1468 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1470 * src/.version: increased version number to 2.5.5
1471 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1472 linking is done manually in pic16 port's _linkEdit,
1473 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1474 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1475 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1476 allocate asmop as AOP_ACC,
1477 (aopForRemat): added parameter 'bool result' in function declaration,
1478 (pic16_aopGet): return AOP_ACC when accessing WREG,
1479 (pic16_popGetTempReg): minor modification,
1480 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1481 'pic16_allocWithIdx',

1488 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1490 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1491 call to allocReg, not by manually allocating a new one,
1492 (pic16_assignRegisters): now before going through the register
1493 allocating functions mark all registers as free. This eliminates some
1494 side effects resulting from peephole parser done earlier in the backbone
1496 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1498 * src/SDCCicode.c (geniCodeLogic),

1518 (aopForSym, aopOp): increment asmop.allocated if reused,
1519 (freeAsmop): decrement asmop.allocated and check for zero instead of
1521 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1522 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1523 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1546 2006-03-06 Borut Razem <borut.razem AT siol.net>
1548 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1549 made the linker quiet
1551 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1553 * src/pic16/gen.c (genPcall): fixed bug #1443644
1554 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1555 which dumps before the function entry point a data byte which represents
1556 the number of the local variables used by the specified function, added
1557 'xinst' for initial support for Extended Instruction Support,
1558 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1559 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1560 port->fun_prefix anymore (may change later),
1561 (genFunction, genEndFunction): do not store/restore local registers for
1562 _main (this should take care the --main-return command line option in
1564 (genOr): removed some legacy pic-port instructions,
1565 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1566 performing operations with SFR's causes data to be written more than
1567 once to each SFR. Perhaps SFRs should be handled in special cases...
1568 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1570 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1571 into account for stack starting position,
1572 (struct OPTIONS pic16_optionsTable): added command line argument
1573 --extended or -y for Extended Instruction Support,
1574 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1575 (deassignLRs): *** perhaps the most important change, old 'for' code
1576 (commented out for reference), didn't account for some registers which
1577 were left marked 'not free' after a pointer operation. The change
1578 reduces register usage a lot in some cases
1580 2006-03-04 Borut Razem <borut.razem AT siol.net>
1582 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3853 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3854 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3855 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3856 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3857 always available in leading double underscore form. The C99 support is
3858 mostly missing, but it's a start.
3859 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3860 reserved identifier "__data".
3862 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3905 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3906 immedDom() returning wrong block; probably fixes bug #1160833)
3908 2005-03-20 Borut Razem <borut.razem AT siol.net>
3910 * support/scripts/inc2h.pl: WIN32 port
3912 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3914 * device/lib/makefile.in: added abs.c and labs.c
3916 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3918 * device/include/stdint.h: added
3919 * device/lib/abs.c: added
3920 * device/lib/labs.c: added
3921 * device/include/stdlib.h: added abs() and labs() prototypes
3922 * device/lib/libsdcc.lib: added abs and labs
3923 * device/include/float.h,

3936 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3938 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3940 * device/lib/printf_large.c: removed inline assembly for portability and
3941 readability. Use printf_fast if speed or size are more important.
3942 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3943 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3945 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3947 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3948 prevent compiler warning
3950 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3952 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3953 moved to level 0 and declared as static. Also they are explicit
3954 placed in access bank. This was necessery because some times they
3955 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3956 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3957 optimizations. Currently only compare to unsigned char is implemented,
3958 * src/pic16/gen.c: added fReturnIdx array,
3959 * (struct resolvedIfx) is moved to gen.h and made public,
3960 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3961 * (aopForSym): added an optimization to directly store in stack of
3962 the operand of a SEND iCode,
3963 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3964 but as registers instead (AOP_REG) using the fReturnIdx array,
3965 * (pic16_freeAsmop): remove the freed register from the
3966 _G.sregsAlloc field,
3967 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3968 a compare of 'WREG',
3969 * (pic16_popGetTempRegCond): changed function prototype, now
3970 function takes also a bitVector argument v which holds the current
3971 set of registers that are allocated for stack access by aopForSym,
3972 registers allocated in aopForSym for accessing stack symbols are not
3973 any more part of the functions usedRegs field,
3974 * (genCall): some times aopOp is called for a stack variable to be
3975 send, aopForSym might perform the push, if this is true make sure
3976 that genCall doesn't push the variable twice by testing _G.resDirect,
3977 * (genFunction): changed testing for unspecified interrupt number
3978 from 256 to INTNO_UNSPEC,
3979 * modified selection scheme of frame pointer generation. Previously
3980 if function did use local registers a frame pointer was generated,
3981 now a frame pointer is generated only if function has arguments
3982 (that need PLUSW2 register access), or has stack arguments, or the
3983 compiler is not instructed to omit the frame pointer,
3984 * (genEndFunction): before restoring local registers that were saved
3985 in the function preamble, also restore the registers that *might*
3986 have been allocated for stack access,
3987 * (genRet): removed some old comments,
3988 * (genCmp, the active (RN's) version): added a call to the
3989 pic16_genCmp_special function to perform the compare with a more
3990 robust and optimized way,
3991 * (genInline): a feature has been added in inline code generation,
3992 which allows a wildcard variable substitution when writing inline
3993 assembly. Code is incomplete and experimental therefore undocumented,
3994 * (genCast): changed order of aopOp for result and right to allow
3995 aopForSym to directly load the result if possible,
3996 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3997 perform an optimized compare on some selected special occasions,
3998 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3999 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4000 generate an IVT any more,
4001 * src/pic16/main.c (pic16_optionsTable): added command line option
4003 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4004 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4006 * src/pic16/NOTES: Raphael Neider added in list of active developers
4007 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4008 jumptable_end to prevent bug #,
4009 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4010 inCond and outCond fields,
4011 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4012 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4013 turn off register spilling,
4014 * (packRegsForOneUse): synced with other ports' versions although it
4015 is not used currently,
4016 * (pic16_packRegisters): added an optimization while reading
4017 structure bitfields, some registers may be saved (malloc code is
4018 decreased by 80 bytes)
4020 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4022 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4023 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4024 this can be optimized more?
4026 2005-03-10 Raphael Neider <rneider AT web.de>
4028 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4029 genNearPointerGet): (hopefully) fixed access to bitfields via
4030 pointers (p->bitN = x; and x = p->bitN; failed)
4032 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4220 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4221 this might fix SIGSEGVs on MinGW...
4222 * src/SDCCopt.c (killDeadCode): restored original behaviour
4223 (volatile operands might get thrown away though)
4225 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

4357 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
4358 accessing SFRs. Updated all occurences of modification of stack or
4359 frame pointer in gen.c and pcode.c,

4664 Adding support for replacing ljmps with sjmps in jumptables
4665 generated for switch statements. For now you need to set the
4666 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4667 Now 4 algorithms for mcs51 jumptable generation are used:
4668 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4669 addresses loaded pc-relative for up to 112 cases and stack-pushing
4670 target addresses loaded with offset from dptr for up to 256 cases.

4697 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4698 to call when a stack overflow occurs,
4699 * (malloc.h): added CVS Id tag,
4700 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4702 * added libc directory. The current version of LibC contains string
4703 functions, ctype functions and macros and some functions of the
4704 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4705 be extensively tested in the future. Standard disclaimer here.
4706 Library is not automatically build yet. But one can build it by
4707 invoking 'make' inside the libc directory.
4708 * added ADC library under libio. Preliminary version yet.
4710 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4713 * (pic16_popGetTempReg): removed warning messgae when allocating
4714 temporary registers, its a buggy feature and will be removed,
4715 * (pic16_popGet): set register instance field in AOP_CRY,
4716 * (pic16_outBitC): fixed for results in size greater than 1,
4717 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4718 * (pic16_storeForReturn): optimized return of 0,
4719 * (genCmp): experimental code for new genCmp which uses PIC18's
4720 special compare&skip instructions. Initial tests fail some times
4721 with variables grater than 1 byte in size, so new code is disabled,
4722 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4724 * (genCast): began a fix to optimize the casting of a bit to another
4725 bit, now assigning a bitfield to another bitfield will fail, sorry,
4726 * src/pic16/main.c: disabled the use of lr-support feature,

7748 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7750 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7751 loaded with the linker search paths (-L arguments) and the libraries
7752 to be linked with the current source (-l arguments). Changes
7753 currently will affect only the pic16 port.
7754 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7755 include path the port specific paths and port specific libraries,
7756 * gplink command now contains the $3 argument,
7757 * src/pic16/device.h,
7758 * src/pic16/device.c,: structure PIC_device is made public and
7759 renamed to PIC16_device, the same for variable Pics which is renamed

7774 Documenting changes from previous commits.
7775 * configure.in (version 1.56),
7776 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7777 when generating output files to configure the pic16 library,
7778 but now I've commented it out, since gputils aren't installed in the
7779 SF compile farm, so library won't compile
7781 * device/lib/Makefile.in (version 1.56): initially I've added in
7782 target 'all' the prerequestive 'model-pic16' so it compiled the
7783 pic16 library, but now I've commented it out for the same reasons
7785 * added targets 'model-pic16' and 'objects-pic16' to compile the
7787 * added target 'port-specific-objects-pic16' to handle the
7788 generated libraries and copy them into the build/ directory
7789 * added target 'clean-intermediate-pic16' to clean intermediate
7790 files into pic16 directory
7791 * in target 'installdirs' added line to create directory pic16 in
7792 the installation path
7794 * device/include/Makefile.in (version 1.11): in target 'install'
7795 added lines to copy all header files to installation path,
7796 * in target 'installdirs' added line create directory for pic16
7797 headers in the installation path

7813 option so that it actually works. Made it specific to the z80, since
7814 the gbz80 doesn't have these kinds of I/O ports.
7816 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7840 Mainly changes to support compilation of the device libraries
7841 * src/pic16/device.c: stack is allocated via symbol and not
7842 via literal number. The symbol is placed in the corresponding
7843 position of the data ram
7844 * (pic16_dump_section): relocatable and absolute uninitialized
7845 data are now emitted in sorted order to reduce section naming,
7846 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7847 weren't marked as being in the access bank,
7849 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7851 Added portion of GNU PIC Library under the directory
7852 device/include/pic16 and device/lib/pic16. These files
7853 contain the declarations of SFRs for the PIC18Fxx2 devices.
7854 The directory is initialized via configure from toplevel.
7856 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

7883 * doc/sdccman.lyx: Moved and added some sections, small changes
7884 all over. Telling LaTeX to be less strict with word spacing
7885 to better keep the right margin. Changed some notes about
7886 maintainance of the ports in section 3.2.1 - is it OK like this?
7888 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7926 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7928 * src/pic16/peeph.def: all peepholes with movff are commented out,
7929 because there is a problem in the pcode peep optimizer,
7930 * src/pic16/ralloc.c: the register allocator can now reuse local
7931 function symbols for another function. This saves register usage.
7932 * src/pic16/ralloc.h: added flag isLocal in structure regs,
7934 Added file src/pic16/NOTES with information about program writing on
7935 the current port version.

7967 2004-01-09 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7970 * src/z80/main.c: added missed needLinkerScript flags (more than
7971 one port structure defined in these file)
7972 * src/ds390/gen.c (aopForSym, aopOp, operandsEqu, aopOp3): fixed

8007 2004-01-07 Borut Razem <borut.razem AT siol.net>
8009 * support/scripts/sdcc.nsi: update PATH
8010 * support/scripts/sdcc.ico: craeted

8023 include information about variables allocated to the overlay
8026 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8028 * as/mcs51/lkmain.c: Help about -Y option

8040 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8042 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8043 (default behaviour).
8045 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8047 A python script to validate compiler diagnostic messages. It can be
8048 used to verify that sdcc complains about bad c source code and
8049 gives a good location of the error.
8050 * support/valdiag/Makefile,
8051 * support/valdiag/valdiag.py,
8052 * support/valdiag/tests/*
8054 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8068 around the header file.
8069 Bug reported from Jesus Calvino-Fraga
8071 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8073 * sdcc.spec: updated
8074 * device/include/Makefile.in: don't install CVS directories
8075 * device/lib/Makefile.in: added removal of CVS directories after install
8076 * doc/Makefile: fixed install, added local_icons
8077 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8078 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8079 * src/ds390/gen.c (genRightShift): fixed bug #870788
8080 * src/SDCCast.c (decorateType): fixed bug #870781
8082 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8084 PIC16 port related changes:
8085 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8086 added variable stackPos,
8088 * gen.c: genCall, assignResultValue: added support for
8089 pushing/retrieving function parameters to/from stack,
8090 genFunction,genEndFunction: setup stack frame for the
8092 genAddrOf: will be changed according to bug 863624
8094 * added files genutils.c and genutils.h which contain gen*
8095 debugged and optimised functions extracted from gen.c
8097 * glue.c: added variable 'externs' which holds extern symbols,
8098 pic16emitRegularMap: is modified to properly handle relocatable
8099 symbols under the new scheme,
8100 pic16createInterruptVect: is modified
8101 pic16printPublics: is modified to emit 'global' assembler directives,
8102 added pic16_printExterns to print extern symbols,
8103 pic16glue: initializes stack/frame pointer in the beginning of
8104 the assembly output. Temporary hack, will be corrected later,
8105 because gplink yet does not support stack and SDCC does not
8106 yet support a type of crt0.o object to create the final binary.
8108 * Removed many lines that contain 8051 legacy code.
8109 * The code is finally placed under a 'code' directive.
8110 * Added port specific options.
8112 * _process_pragma: simplified since now we do not need *special*
8113 include file to define SFR registers. But a separate header
8114 will be needed. This will be developed later.
8115 * _pic16_parseOptions: added, parses port specific options:
8116 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8117 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8118 --preplace-udata-with=
8120 * _pic16_setDefaultOptions: modified to initialize section names,
8121 but hack is temporarly out of order since it needs improvement.
8122 * _pic16_genAssemblerPreamble: configuration words are emitted by
8123 their address instead of their name. This part is incomplete and
8124 supports only the 18Fxx2 devices. Other devices will emit an error
8125 during assembly since they do not contain the same set of config
8127 * _pic16_genIVT: is modified,
8129 * pcode.c: added definitions for some hardware registers that are needed
8131 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8132 All PCI entries are updated. Now LFSR is supported.
8133 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8134 * added pic16_newpCodeOpLit2 to support instructions with
8135 two literal arguments
8136 * pic16_pCode2str: corrected code that emits assembler instructions
8137 with two literal operands and those that have an access bit modifier
8138 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8139 this fixes a bug which caused some labels to be lost, when an
8140 assembler directive was added, i.e. banksel,
8141 * pic16_FixRegisterBanking: improved logic that causes the insertion
8143 * InlineFunction: functions that are called once, are not any more
8144 inlined. This can be a port option in the future,
8146 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8148 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8149 hold the corresponding uninitialized symbols,
8150 * pic16_allocProcessorRegister: registers have explicit marked the
8152 * pic16_allocInternalRegister: registers are explicit marked as
8154 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8155 processing list, so bit registers were lost,
8158 * ralloc.h: added field 'accessBank' and original symbol operand
8159 in register definition,
8160 * removed the field isMapped from register definition,
8162 ** Several functions have been removed from various sources:
8163 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8164 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8165 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8166 pic16_assignRelocatableRegisters
8168 ** others have been introduced:
8169 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8170 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8172 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8174 * support/scripts/inc2h.pl: changed definition of BIT_AT
8175 to emit 'sbit at' instead of 'bit at'. This was a request.
8177 PIC16 port related preliminary changes:
8178 * gen.c: prefixed function popRegFromString with
8179 pic16_ and all references to it corrected
8180 * pcode.c: all pic16_pc_* hardware registers prefixed
8181 with underscore (_),
8182 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8183 * ralloc.c: newReg(): when register is REG_SFR then
8184 set address to rIdx,
8185 pic16_allocProcessorRegister(): marks register wasUsed=0
8186 pic16_writeUsedRegs(): added a call to assign processor
8187 registers via pic16_assignFixedRegisters
8189 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8191 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8192 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8193 variables in unused register banks. Also the SSEG is placed
8194 wherever there is enough space for it, and IDATA can be anywhere
8195 in internal RAM. For now compile using -Wl-Y[stack_size].
8196 The mem file is different for this option as well, since it
8197 makes no sense of talking about DSEG lenght.
8199 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8201 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8202 in certain cases, e.g. when ROM assignment, patch provided
8203 from Albert den Haan.
8205 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8346 xdata and data memory on startup. Set the environment variable
8347 SDCC_NOGENRAMCLEAR to disable this.
8348 * src/mcs51/peephole.def,
8349 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
8350 (allows non-interrupt and interrupt code to safely compete for a resource
8351 without the non-interrupt code having to disable interrupts)
8353 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8355 * src/SDCCicode.c (geniCodeAdd),
8356 * src/SDCCast.c (decorateType): fixed bug #857753 (need to be careful

8370 2003-12-12 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8372 * src/mcs51/main.c(_mcs51_genRAMCLEAR): using r0 instead of r1/r2.
8373 Apparently this did not see much testing (endless loop)
8375 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8377 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165
8379 2003-12-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8448 it breaks with bitfields, extern declarations, and gcse analysis.
8449 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8450 could be assigned through a pointer, so don't complain.

9228 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9229 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9230 type for bits was changed. It resulted in bit variables becoming
9231 global, which is not permitted in PIC 14 assembly output.

9248 A few small changes that speed up the peephole optimizer.
9252 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9254 Try to make the peephole optimizer smarter by maintaining
9255 an association between the assembly source code and the
9256 iCodes that originated them. Put this information to use
9257 with a new peephole rule condition "notVolatile" so that
9258 the rules can be aggressive yet still safe.
9263 * src/mcs51/peeph.def
9265 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9269 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9270 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9271 if the left or right operand symbols have the accuse flag set.
9273 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9275 Changed the type of the result of the ! (NOT) operator to char;
9276 previously it returned the same type as the source. This allows
9277 us to eliminate all the genFloatNot functions (all of its target
9278 implementations were very buggy) since !float can use the same
9281 * src/SDCCicode.c (ast2iCode): ! returns char

9290 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9291 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9292 during interrupts. Ensure WSAVE is located at a shared bank address.
9293 2. Fixed page selection in some places
9294 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9295 the registers name strings.
9296 4. Fixed "signed / unsigned compare" compiler warnings.
9297 5. The PIC port manages its own allocation of the general purpose
9298 registers, but makes no attempt to reuse them. As a result when
9299 compiling it soon runs out of general purpose registers. Some
9300 additional code was added to the files pcode.c and device.c to walk
9301 through the function call tree and rename the registers so that they
9311 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9312 genPlus() & genMinus() when the result is the same as left or right

9318 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9320 Made bitfield a distinct type from bit so that bitfields
9321 convert as per ANSI C and bits retain their traditional
9322 boolean style behaviour. Implemented bitfield support in
9330 * src/ds390/gen.c: bit v bitfield split
9331 * src/z80/gen.c: New support for bitfields
9332 * support/regression/tests/bitfields.c: reenabled z80,
9335 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9337 Rules 246.x, 247.x relate to bitfields, the others speed up
9338 access to xdata mapped I/O devices.

9386 Made the constant following the "interrupt" keyword optional. If
9387 omitted, the function will not automatically be given an entry
9388 in the interrupt vector table (similar to #pragma NOIV, but
9389 less syntacticly kludgy). The interrupt number is also now
9390 range checked. Also fixed a bug in the high order bit example

9916 * configure.in: configure for pic16 port,
9917 added --disable-pic16-port
9918 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9919 * src/SDCCmain.c: linkOptions is changed to set *,
9920 added if/endif conditional macros to remove options help
9921 messages from optionsTable when a port is not configured, added
9922 support for the PIc16 port in the ports table, when executing
9923 the compiler with no port specified on command line, a default
9924 port is selected with the new macro DEFAULT_PORT which is
9925 defined in port.h, in setDefaultOptions() linkOptions is removed
9926 from initialization assignment, since now it is a set,
9927 parseCmdLine uses setParseWithComma for linkOptions, in
9928 linkEdit() linkOptions are accessed with new function indexSet()
9929 which returns the i'th item of a set variable. See SDCCset.c, in
9930 linkEdit() when calling buildCmdLine(), added linkOptions as
9931 last argument. Now users can pass arguments to gplink via the
9932 -Wl option, main() uses pic16glue() to glue up pic16 programs
9933 * src/SDCCpeeph.c: various changes to support pic16
9934 * src/SDCCset.c: added function void *indexSet(set *, int) to
9935 return the i'th item of the set

9938 * src/clean.mk: added pic16 in CLEANALLPORTS variable
9939 * src/port.h: added TARGET_ID_PIC16,TARGET_IS_PIC16 macro,
9940 added macro DEFAULT_PORT
9941 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
9942 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
9944 * src/pic16/glue.c: commented out some error producing lines
9945 * src/pic16/main.c: __config directives are commented out to stop
9946 gpasm complaining and test the linkage with gplink, _linkCmd and
9947 _asmCmd changed to be more gplink and gpasm friendly
9948 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9949 produced an error when parsed, peep rule 12 is added to utilize
9950 movff, but it is commented out since the pCode does not support
9951 yet a command with 2 address arguments
9953 2003-05-18 <johan AT balder>
9955 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9982 2003-05-11 Borut Razem <borut.razem AT siol.net>
9984 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9985 the path of bin directory, so that PATH is the only env. variable, which has to be set
9986 in case of standard installation.
9987 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

11014 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11016 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11018 * in /sdcc/as/mcs51/ changed these files in order to create an
11019 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11020 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11021 following files to include the previous two files: aslink.dsp,
11022 Makefile.aslink, Makefile.bcc, and Makefile.in.
11024 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11025 .adb instead of .cdb
11027 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11029 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11030 value from option --iram-size.
11032 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11034 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11037 2002-09-18 <wiml AT hhhh.org>
11039 * SDCClrange.h: exposed setFromRange() and setToRange()
11040 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11041 packRegsForAccUse() (bug 542397)
11042 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11043 multiple times and emitting the fetch operations more than once
11044 added aopGetUsesAcc() function to allow binary operators to
11045 fetch their operands in the correct order; made genMinus() emit
11046 compact code for X = LITERAL - Y
11048 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11049 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11050 sprintf() in line 1267.
11052 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11053 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11056 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11057 Changes to aslink (All the changes are marked with 'JCF'):
11059 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11062 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11063 area BSEG. Also moves, if possible, the DATA area down into the internal
11064 ram so more space is available.
11066 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11069 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11070 not bytes. Function summary() which creates a memory usage summary
11071 file with extension .mem. Reports of overlaping stack and small stack
11072 size. If the space for the stack is less than 16 bytes aslink trows a
11075 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11076 the 8051. Option 'y' for memory summary output file.
11078 Changes to sdcc (All the changes are marked with 'JCF'):
11080 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11082 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11083 overlaying area for it (uses RegBankUsed[4]).
11085 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11086 bank zero as used by default. By default aslink locates the stack
11087 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11088 the creation of the .mem file. Delegates the allocation of data area
11089 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11090 the begining of the stack area to aslink.
11092 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11093 glue() in SDCCglue.c creates an area for it.
11095 2002-09-03 Borut Razem <borut.razem AT siol.net>
11096 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11097 sdcc/src/pic/glue.c:
11098 introduced atexit() handler for teporay files removal in case of
11099 errors, assertions, ...
11101 2002-08-29 Borut Razem <borut.razem AT siol.net>
11102 * sdcc/support/cpp2/auto-host_vc_in.h:
11103 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11104 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11105 Maybe there is a similar problem with BORLANDC? It should be checked!
11107 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11108 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11109 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11110 was not executed, and the compiler (cl) launched a warning:
11111 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11113 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11114 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11116 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11117 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11119 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11120 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11121 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11122 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11123 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11124 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11125 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11126 - added Release configuration in VS projects
11127 - review of compiler an linker options
11128 - VC .exe files are generated in bin_vc directory, not to interfere
11129 with binaries generated from other projects (cygwin, mingw, bcc ...)
11131 * sdcc/src/yacc.dsp: added
11133 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11134 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11135 and insert the version number definitions from .version
11137 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11139 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11140 added - genarate auto-host.h using auto-host_vc_in.h as template
11143 removed from CVS, generated automatically
11145 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11146 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11148 2002-08-11 Borut Razem <borut.razem AT siol.net>
11149 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11151 2002-08-10 Borut Razem <borut.razem AT siol.net>
11152 * src/SDCCmain.c (main):
11153 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11154 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11155 The consequence was that some temporary files were not removed.
11158 unification of code in functions tempfilename() and tempfile():
11159 function tempnam() is defined in Visual Studio 6.0 and .NET
11161 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11163 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11164 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11165 - removed compiler command line option /WX: Treats all warnings as errors
11166 - update a list of source files, included into the project
11168 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11169 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11170 changed project type to Generic Project so that can be correcly converted to VS.NET project

11185 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11186 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11187 - solved MSC error in function aopDump()

11367 Previous fix was not good. basic blocks that have "break" or "return" are
11368 not really partof a loop , but live ranges used in these blocks should

12212 2001-09-03 Michael Hope <michaelh AT juju.net.nz>
12214 * link/z80/aslink.h: Fixed path for PATH_MAX
12216 2001-09-02 Michael Hope <michaelh AT juju.net.nz>
12218 * src/z80/gen.c (fetchLitPair): Changed so that it properly caches direct space references.
12220 * support/regression/tests/addsub.c: Added cases to cover all the +, - combinations.
12222 * support/regression/tests/uminus.c: Added a test for the unary minus operator.
12224 * src/z80/gen.c (genUminus): Fixed add, sub, and uminus on the gbz80 port for longs. Had to shift some functions about to do it.
12226 2001-09-01 Michael Hope <michaelh AT juju.net.nz>
12228 * src/z80/gen.c: Fixed up generator to pass the regresion tests, specifically fixing loads for longs, genCmp, and turned on the map file.
12229 (genCmp): Fixed up genCmp for the GB with longs.
12231 * device/lib/gbz80/Makefile: Fixed up all the libraries to pass the regression tests.
12233 * support/regression/ports/host/spec.mk: Updated to compile with the new type specifiers.
12235 * device/lib/Makefile.in (Z80SOURCES): Removed old _mululong, _mulslong, and unneeded _mulint.
12237 * device/lib/_mullong.c (_mulslong): Changed to actually return a value :)

12241 * added peepholes 223 to 231 to mcs51 port. These improve code when using large model.
12243 2001-08-30 Michael Hope <michaelh AT juju.net.nz>
12245 * device/lib/gbz80/crt0.s (init): Fixed up support for the gbz80 such that it will at least run (and fail badly) the regression tests.
12247 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
12249 2001-08-29 Michael Hope <michaelh AT juju.net.nz>
12251 * link/z80/aslink.h: Fixed long file name support. Is now based off PATH_MAX instead of a constant.
12253 * src/z80/gen.c: Fixed add and sub for the case where left or right are in static space.
