1138 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1140 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1141 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1143 One basic decision: e.g. src/clean.mk includes further files. In order
1144 to make this work there are two solutions:
1145 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1146 run configure on them. This way they can use
1147 'include $(srcdir)/port-clean.mk'
1148 - always include clean.mk by the Makefile at the same level. To avoid
1149 that `make clean` tries to include and build Makefile.dep the
1150 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1151 implemented, because now even `make uninstall` doesn't create
1152 Makefile.in. clean.mk could be eliminated by pasting it in
1155 * debugger/mcs51/Makefile.in: build own objects from library sources
1156 (SLIB, SDCC) in current directory
1158 * configure, configure.in: renamed --disable-device-lib-build in
1159 --disable-device-lib; added --enable-doc, the required tools are
1160 searched by configure; added result message; the toolchain for the
1161 belonging ports are now only built, if the port is enabled.
1163 * support/regression/*: all output is written in directory gen, because
1164 the fwk and ports directories don't livet in the build tree using vpath
1166 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1167 --disable-device-lib, added --enable-doc, added section VPATH
1169 * sim/ucsim/configure.in,
1170 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1171 z80 are enabled by default
1173 2006-04-24 Raphael Neider <rneider AT web.de>
1175 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1176 to config word, "pic14_"-prefixed some extern functions
1177 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1178 config word has been found
1179 * src/pic/device.h: added prototypes
1180 * src/pic/pcode.c: added "pic14_"-prefix where needed
1181 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1183 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1197 fixes #1469504 and #1474602,
1198 (pCodeRegOptimizeRegUsage): fixed typo in comment

1421 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1423 * src/mcs51/gen.c (genCall): fixed bug 1457608
1425 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1430 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1432 * src/SDCCpeeph.c (operandsLiteral): new, added,

1444 implemented patch 1120823 Thanks to Willy De la Court (normal
1445 interrupts need an interrupt number now if they are made critical),
1446 and enabled nesting of critical functions though not for gbz80
1447 (genCritical, genEndCritical): added functions
1448 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1449 * src/z80/mappings.i: added "ei" to all mappings

1461 the left operand is shorter than the result (c* = lit-c* + int),
1463 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1466 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1468 * src/.version: increased version number to 2.5.5
1469 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1470 linking is done manually in pic16 port's _linkEdit,
1471 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1472 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1473 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1474 allocate asmop as AOP_ACC,
1475 (aopForRemat): added parameter 'bool result' in function declaration,
1476 (pic16_aopGet): return AOP_ACC when accessing WREG,
1477 (pic16_popGetTempReg): minor modification,
1478 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1479 'pic16_allocWithIdx',

1486 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1488 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1489 call to allocReg, not by manually allocating a new one,
1490 (pic16_assignRegisters): now before going through the register
1491 allocating functions mark all registers as free. This eliminates some
1492 side effects resulting from peephole parser done earlier in the backbone
1494 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1496 * src/SDCCicode.c (geniCodeLogic),

1516 (aopForSym, aopOp): increment asmop.allocated if reused,
1517 (freeAsmop): decrement asmop.allocated and check for zero instead of
1519 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1520 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1521 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1544 2006-03-06 Borut Razem <borut.razem AT siol.net>
1546 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1547 made the linker quiet
1549 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1551 * src/pic16/gen.c (genPcall): fixed bug #1443644
1552 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1553 which dumps before the function entry point a data byte which represents
1554 the number of the local variables used by the specified function, added
1555 'xinst' for initial support for Extended Instruction Support,
1556 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1557 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1558 port->fun_prefix anymore (may change later),
1559 (genFunction, genEndFunction): do not store/restore local registers for
1560 _main (this should take care the --main-return command line option in
1562 (genOr): removed some legacy pic-port instructions,
1563 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1564 performing operations with SFR's causes data to be written more than
1565 once to each SFR. Perhaps SFRs should be handled in special cases...
1566 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1568 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1569 into account for stack starting position,
1570 (struct OPTIONS pic16_optionsTable): added command line argument
1571 --extended or -y for Extended Instruction Support,
1572 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1573 (deassignLRs): *** perhaps the most important change, old 'for' code
1574 (commented out for reference), didn't account for some registers which
1575 were left marked 'not free' after a pointer operation. The change
1576 reduces register usage a lot in some cases
1578 2006-03-04 Borut Razem <borut.razem AT siol.net>
1580 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3851 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3852 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3853 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3854 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3855 always available in leading double underscore form. The C99 support is
3856 mostly missing, but it's a start.
3857 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3858 reserved identifier "__data".
3860 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3903 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3904 immedDom() returning wrong block; probably fixes bug #1160833)
3906 2005-03-20 Borut Razem <borut.razem AT siol.net>
3908 * support/scripts/inc2h.pl: WIN32 port
3910 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3912 * device/lib/makefile.in: added abs.c and labs.c
3914 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3916 * device/include/stdint.h: added
3917 * device/lib/abs.c: added
3918 * device/lib/labs.c: added
3919 * device/include/stdlib.h: added abs() and labs() prototypes
3920 * device/lib/libsdcc.lib: added abs and labs
3921 * device/include/float.h,

3926 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3928 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed

3934 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3936 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3938 * device/lib/printf_large.c: removed inline assembly for portability and
3939 readability. Use printf_fast if speed or size are more important.
3940 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3941 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3943 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3945 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3946 prevent compiler warning
3948 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3950 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3951 moved to level 0 and declared as static. Also they are explicit
3952 placed in access bank. This was necessery because some times they
3953 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3954 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3955 optimizations. Currently only compare to unsigned char is implemented,
3956 * src/pic16/gen.c: added fReturnIdx array,
3957 * (struct resolvedIfx) is moved to gen.h and made public,
3958 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3959 * (aopForSym): added an optimization to directly store in stack of
3960 the operand of a SEND iCode,
3961 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3962 but as registers instead (AOP_REG) using the fReturnIdx array,
3963 * (pic16_freeAsmop): remove the freed register from the
3964 _G.sregsAlloc field,
3965 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3966 a compare of 'WREG',
3967 * (pic16_popGetTempRegCond): changed function prototype, now
3968 function takes also a bitVector argument v which holds the current
3969 set of registers that are allocated for stack access by aopForSym,
3970 registers allocated in aopForSym for accessing stack symbols are not
3971 any more part of the functions usedRegs field,
3972 * (genCall): some times aopOp is called for a stack variable to be
3973 send, aopForSym might perform the push, if this is true make sure
3974 that genCall doesn't push the variable twice by testing _G.resDirect,
3975 * (genFunction): changed testing for unspecified interrupt number
3976 from 256 to INTNO_UNSPEC,
3977 * modified selection scheme of frame pointer generation. Previously
3978 if function did use local registers a frame pointer was generated,
3979 now a frame pointer is generated only if function has arguments
3980 (that need PLUSW2 register access), or has stack arguments, or the
3981 compiler is not instructed to omit the frame pointer,
3982 * (genEndFunction): before restoring local registers that were saved
3983 in the function preamble, also restore the registers that *might*
3984 have been allocated for stack access,
3985 * (genRet): removed some old comments,
3986 * (genCmp, the active (RN's) version): added a call to the
3987 pic16_genCmp_special function to perform the compare with a more
3988 robust and optimized way,
3989 * (genInline): a feature has been added in inline code generation,
3990 which allows a wildcard variable substitution when writing inline
3991 assembly. Code is incomplete and experimental therefore undocumented,
3992 * (genCast): changed order of aopOp for result and right to allow
3993 aopForSym to directly load the result if possible,
3994 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3995 perform an optimized compare on some selected special occasions,
3996 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3997 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3998 generate an IVT any more,
3999 * src/pic16/main.c (pic16_optionsTable): added command line option
4001 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4002 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4004 * src/pic16/NOTES: Raphael Neider added in list of active developers
4005 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4006 jumptable_end to prevent bug #,
4007 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4008 inCond and outCond fields,
4009 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4010 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4011 turn off register spilling,
4012 * (packRegsForOneUse): synced with other ports' versions although it
4013 is not used currently,
4014 * (pic16_packRegisters): added an optimization while reading
4015 structure bitfields, some registers may be saved (malloc code is
4016 decreased by 80 bytes)
4018 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4020 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4021 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4022 this can be optimized more?
4024 2005-03-10 Raphael Neider <rneider AT web.de>
4026 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4027 genNearPointerGet): (hopefully) fixed access to bitfields via
4028 pointers (p->bitN = x; and x = p->bitN; failed)
4030 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4218 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
4219 this might fix SIGSEGVs on MinGW...
4220 * src/SDCCopt.c (killDeadCode): restored original behaviour
4221 (volatile operands might get thrown away though)
4223 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

4311 copy the third byte from the int -- now assumes 0x80 (data memory)
4312 * src/pic16/genarith.c (pic16_genPlus): fixed bug when swapping
4313 operands (genAddLit expects the iCode's operands to swapped as
4314 well), fixed leftover bytes (crashed for short left operands)

4355 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
4356 accessing SFRs. Updated all occurences of modification of stack or
4357 frame pointer in gen.c and pcode.c,
4358 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
4359 assigning of a literal value to pointers,

4387 to hold the condition bit)
4388 * added new version of genCmp (old code available via #define)
4389 * added new version of genShiftLeft/genShiftRight in a generic
4390 way, now supports shifting by negative values

4662 Adding support for replacing ljmps with sjmps in jumptables
4663 generated for switch statements. For now you need to set the
4664 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4665 Now 4 algorithms for mcs51 jumptable generation are used:
4666 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4667 addresses loaded pc-relative for up to 112 cases and stack-pushing
4668 target addresses loaded with offset from dptr for up to 256 cases.

4695 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4696 to call when a stack overflow occurs,
4697 * (malloc.h): added CVS Id tag,
4698 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4700 * added libc directory. The current version of LibC contains string
4701 functions, ctype functions and macros and some functions of the
4702 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4703 be extensively tested in the future. Standard disclaimer here.
4704 Library is not automatically build yet. But one can build it by
4705 invoking 'make' inside the libc directory.
4706 * added ADC library under libio. Preliminary version yet.
4708 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4711 * (pic16_popGetTempReg): removed warning messgae when allocating
4712 temporary registers, its a buggy feature and will be removed,
4713 * (pic16_popGet): set register instance field in AOP_CRY,
4714 * (pic16_outBitC): fixed for results in size greater than 1,
4715 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4716 * (pic16_storeForReturn): optimized return of 0,
4717 * (genCmp): experimental code for new genCmp which uses PIC18's
4718 special compare&skip instructions. Initial tests fail some times
4719 with variables grater than 1 byte in size, so new code is disabled,
4720 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4722 * (genCast): began a fix to optimize the casting of a bit to another
4723 bit, now assigning a bitfield to another bitfield will fail, sorry,
4724 * src/pic16/main.c: disabled the use of lr-support feature,

7746 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7748 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7749 loaded with the linker search paths (-L arguments) and the libraries
7750 to be linked with the current source (-l arguments). Changes
7751 currently will affect only the pic16 port.
7752 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7753 include path the port specific paths and port specific libraries,
7754 * gplink command now contains the $3 argument,
7755 * src/pic16/device.h,
7756 * src/pic16/device.c,: structure PIC_device is made public and
7757 renamed to PIC16_device, the same for variable Pics which is renamed

7772 Documenting changes from previous commits.
7773 * configure.in (version 1.56),
7774 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7775 when generating output files to configure the pic16 library,
7776 but now I've commented it out, since gputils aren't installed in the
7777 SF compile farm, so library won't compile
7779 * device/lib/Makefile.in (version 1.56): initially I've added in
7780 target 'all' the prerequestive 'model-pic16' so it compiled the
7781 pic16 library, but now I've commented it out for the same reasons
7783 * added targets 'model-pic16' and 'objects-pic16' to compile the
7785 * added target 'port-specific-objects-pic16' to handle the
7786 generated libraries and copy them into the build/ directory
7787 * added target 'clean-intermediate-pic16' to clean intermediate
7788 files into pic16 directory
7789 * in target 'installdirs' added line to create directory pic16 in
7790 the installation path
7792 * device/include/Makefile.in (version 1.11): in target 'install'
7793 added lines to copy all header files to installation path,
7794 * in target 'installdirs' added line create directory for pic16
7795 headers in the installation path

7811 option so that it actually works. Made it specific to the z80, since
7812 the gbz80 doesn't have these kinds of I/O ports.
7814 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7840 via literal number. The symbol is placed in the corresponding
7841 position of the data ram
7842 * (pic16_dump_section): relocatable and absolute uninitialized
7843 data are now emitted in sorted order to reduce section naming,
7844 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7845 weren't marked as being in the access bank,
7847 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7849 Added portion of GNU PIC Library under the directory
7850 device/include/pic16 and device/lib/pic16. These files
7851 contain the declarations of SFRs for the PIC18Fxx2 devices.
7852 The directory is initialized via configure from toplevel.
7854 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

7881 * doc/sdccman.lyx: Moved and added some sections, small changes
7882 all over. Telling LaTeX to be less strict with word spacing
7883 to better keep the right margin. Changed some notes about
7884 maintainance of the ports in section 3.2.1 - is it OK like this?
7886 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7924 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7926 * src/pic16/peeph.def: all peepholes with movff are commented out,
7927 because there is a problem in the pcode peep optimizer,
7928 * src/pic16/ralloc.c: the register allocator can now reuse local

8005 2004-01-07 Borut Razem <borut.razem AT siol.net>
8007 * support/scripts/sdcc.nsi: update PATH
8008 * support/scripts/sdcc.ico: craeted

8021 include information about variables allocated to the overlay
8024 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8026 * as/mcs51/lkmain.c: Help about -Y option

8038 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8040 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8041 (default behaviour).
8043 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8045 A python script to validate compiler diagnostic messages. It can be
8046 used to verify that sdcc complains about bad c source code and
8047 gives a good location of the error.
8048 * support/valdiag/Makefile,
8049 * support/valdiag/valdiag.py,
8050 * support/valdiag/tests/*
8052 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8067 Bug reported from Jesus Calvino-Fraga
8069 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8071 * sdcc.spec: updated
8072 * device/include/Makefile.in: don't install CVS directories
8073 * device/lib/Makefile.in: added removal of CVS directories after install
8074 * doc/Makefile: fixed install, added local_icons
8075 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8076 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8077 * src/ds390/gen.c (genRightShift): fixed bug #870788
8078 * src/SDCCast.c (decorateType): fixed bug #870781
8080 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8082 PIC16 port related changes:
8083 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8084 added variable stackPos,
8086 * gen.c: genCall, assignResultValue: added support for
8087 pushing/retrieving function parameters to/from stack,
8088 genFunction,genEndFunction: setup stack frame for the
8090 genAddrOf: will be changed according to bug 863624
8092 * added files genutils.c and genutils.h which contain gen*
8093 debugged and optimised functions extracted from gen.c
8095 * glue.c: added variable 'externs' which holds extern symbols,
8096 pic16emitRegularMap: is modified to properly handle relocatable
8097 symbols under the new scheme,
8098 pic16createInterruptVect: is modified
8099 pic16printPublics: is modified to emit 'global' assembler directives,
8100 added pic16_printExterns to print extern symbols,
8101 pic16glue: initializes stack/frame pointer in the beginning of
8102 the assembly output. Temporary hack, will be corrected later,
8103 because gplink yet does not support stack and SDCC does not
8104 yet support a type of crt0.o object to create the final binary.
8106 * Removed many lines that contain 8051 legacy code.
8107 * The code is finally placed under a 'code' directive.
8108 * Added port specific options.
8110 * _process_pragma: simplified since now we do not need *special*
8111 include file to define SFR registers. But a separate header
8112 will be needed. This will be developed later.
8113 * _pic16_parseOptions: added, parses port specific options:
8114 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8115 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8116 --preplace-udata-with=
8118 * _pic16_setDefaultOptions: modified to initialize section names,
8119 but hack is temporarly out of order since it needs improvement.
8120 * _pic16_genAssemblerPreamble: configuration words are emitted by
8121 their address instead of their name. This part is incomplete and
8122 supports only the 18Fxx2 devices. Other devices will emit an error
8123 during assembly since they do not contain the same set of config
8125 * _pic16_genIVT: is modified,
8127 * pcode.c: added definitions for some hardware registers that are needed
8129 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8130 All PCI entries are updated. Now LFSR is supported.
8131 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8132 * added pic16_newpCodeOpLit2 to support instructions with
8133 two literal arguments
8134 * pic16_pCode2str: corrected code that emits assembler instructions
8135 with two literal operands and those that have an access bit modifier
8136 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8137 this fixes a bug which caused some labels to be lost, when an
8138 assembler directive was added, i.e. banksel,
8139 * pic16_FixRegisterBanking: improved logic that causes the insertion
8141 * InlineFunction: functions that are called once, are not any more
8142 inlined. This can be a port option in the future,
8144 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8146 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8147 hold the corresponding uninitialized symbols,
8148 * pic16_allocProcessorRegister: registers have explicit marked the
8150 * pic16_allocInternalRegister: registers are explicit marked as
8152 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8153 processing list, so bit registers were lost,
8156 * ralloc.h: added field 'accessBank' and original symbol operand
8157 in register definition,
8158 * removed the field isMapped from register definition,
8160 ** Several functions have been removed from various sources:
8161 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8162 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8163 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8164 pic16_assignRelocatableRegisters
8166 ** others have been introduced:
8167 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8168 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8170 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8172 * support/scripts/inc2h.pl: changed definition of BIT_AT
8173 to emit 'sbit at' instead of 'bit at'. This was a request.
8175 PIC16 port related preliminary changes:
8176 * gen.c: prefixed function popRegFromString with
8177 pic16_ and all references to it corrected
8178 * pcode.c: all pic16_pc_* hardware registers prefixed
8179 with underscore (_),
8180 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8181 * ralloc.c: newReg(): when register is REG_SFR then
8182 set address to rIdx,
8183 pic16_allocProcessorRegister(): marks register wasUsed=0
8184 pic16_writeUsedRegs(): added a call to assign processor
8185 registers via pic16_assignFixedRegisters
8187 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8189 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8190 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8191 variables in unused register banks. Also the SSEG is placed
8192 wherever there is enough space for it, and IDATA can be anywhere
8193 in internal RAM. For now compile using -Wl-Y[stack_size].
8194 The mem file is different for this option as well, since it
8195 makes no sense of talking about DSEG lenght.
8197 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8199 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8200 in certain cases, e.g. when ROM assignment, patch provided
8201 from Albert den Haan.
8203 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8343 * src/mcs51/main.c: fixed bug #737001 for the mcs51. SDCC clears
8344 xdata and data memory on startup. Set the environment variable
8345 SDCC_NOGENRAMCLEAR to disable this.
8346 * src/mcs51/peephole.def,
8347 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
8348 (allows non-interrupt and interrupt code to safely compete for a resource
8349 without the non-interrupt code having to disable interrupts)
8351 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8353 * src/SDCCicode.c (geniCodeAdd),
8354 * src/SDCCast.c (decorateType): fixed bug #857753 (need to be careful
8355 with valFromType if type might be a pointer and host is big endian).

8368 2003-12-12 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8370 * src/mcs51/main.c(_mcs51_genRAMCLEAR): using r0 instead of r1/r2.
8371 Apparently this did not see much testing (endless loop)
8373 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8375 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165
8377 2003-12-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8379 * src/SDCCdebug.c (outputDebugSymbols, outputDebugStackSymbols, dumpSymInfo):

8446 it breaks with bitfields, extern declarations, and gcse analysis.
8447 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8448 could be assigned through a pointer, so don't complain.

9226 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9227 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9228 type for bits was changed. It resulted in bit variables becoming
9229 global, which is not permitted in PIC 14 assembly output.

9246 A few small changes that speed up the peephole optimizer.
9250 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9252 Try to make the peephole optimizer smarter by maintaining
9253 an association between the assembly source code and the
9254 iCodes that originated them. Put this information to use
9255 with a new peephole rule condition "notVolatile" so that
9256 the rules can be aggressive yet still safe.
9261 * src/mcs51/peeph.def
9263 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9267 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9268 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9269 if the left or right operand symbols have the accuse flag set.
9271 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9273 Changed the type of the result of the ! (NOT) operator to char;
9274 previously it returned the same type as the source. This allows
9275 us to eliminate all the genFloatNot functions (all of its target
9276 implementations were very buggy) since !float can use the same
9279 * src/SDCCicode.c (ast2iCode): ! returns char

9288 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9289 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9290 during interrupts. Ensure WSAVE is located at a shared bank address.
9291 2. Fixed page selection in some places
9292 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9293 the registers name strings.
9294 4. Fixed "signed / unsigned compare" compiler warnings.
9295 5. The PIC port manages its own allocation of the general purpose
9296 registers, but makes no attempt to reuse them. As a result when
9297 compiling it soon runs out of general purpose registers. Some
9298 additional code was added to the files pcode.c and device.c to walk
9299 through the function call tree and rename the registers so that they
9309 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9310 genPlus() & genMinus() when the result is the same as left or right
9312 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9316 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9318 Made bitfield a distinct type from bit so that bitfields
9319 convert as per ANSI C and bits retain their traditional
9320 boolean style behaviour. Implemented bitfield support in
9328 * src/ds390/gen.c: bit v bitfield split
9329 * src/z80/gen.c: New support for bitfields
9330 * support/regression/tests/bitfields.c: reenabled z80,
9333 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9335 Rules 246.x, 247.x relate to bitfields, the others speed up
9336 access to xdata mapped I/O devices.

9384 Made the constant following the "interrupt" keyword optional. If
9385 omitted, the function will not automatically be given an entry
9386 in the interrupt vector table (similar to #pragma NOIV, but
9387 less syntacticly kludgy). The interrupt number is also now
9388 range checked. Also fixed a bug in the high order bit example

9914 * configure.in: configure for pic16 port,
9915 added --disable-pic16-port
9916 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9917 * src/SDCCmain.c: linkOptions is changed to set *,
9918 added if/endif conditional macros to remove options help
9919 messages from optionsTable when a port is not configured, added
9920 support for the PIc16 port in the ports table, when executing
9921 the compiler with no port specified on command line, a default
9922 port is selected with the new macro DEFAULT_PORT which is
9923 defined in port.h, in setDefaultOptions() linkOptions is removed
9924 from initialization assignment, since now it is a set,
9925 parseCmdLine uses setParseWithComma for linkOptions, in
9926 linkEdit() linkOptions are accessed with new function indexSet()
9927 which returns the i'th item of a set variable. See SDCCset.c, in
9928 linkEdit() when calling buildCmdLine(), added linkOptions as
9929 last argument. Now users can pass arguments to gplink via the
9930 -Wl option, main() uses pic16glue() to glue up pic16 programs
9931 * src/SDCCpeeph.c: various changes to support pic16
9932 * src/SDCCset.c: added function void *indexSet(set *, int) to
9933 return the i'th item of the set

9936 * src/clean.mk: added pic16 in CLEANALLPORTS variable
9937 * src/port.h: added TARGET_ID_PIC16,TARGET_IS_PIC16 macro,
9938 added macro DEFAULT_PORT
9939 * src/pic/main.c: corrected arguments of gplnk in _linkCmd
9940 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
9942 * src/pic16/glue.c: commented out some error producing lines
9943 * src/pic16/main.c: __config directives are commented out to stop
9944 gpasm complaining and test the linkage with gplink, _linkCmd and
9945 _asmCmd changed to be more gplink and gpasm friendly
9946 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9947 produced an error when parsed, peep rule 12 is added to utilize
9948 movff, but it is commented out since the pCode does not support
9949 yet a command with 2 address arguments
9951 2003-05-18 <johan AT balder>
9953 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9978 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9980 2003-05-11 Borut Razem <borut.razem AT siol.net>
9982 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9983 the path of bin directory, so that PATH is the only env. variable, which has to be set
9984 in case of standard installation.
9985 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

11011 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11012 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11014 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11016 * in /sdcc/as/mcs51/ changed these files in order to create an
11017 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11018 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11019 following files to include the previous two files: aslink.dsp,
11020 Makefile.aslink, Makefile.bcc, and Makefile.in.
11022 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11023 .adb instead of .cdb
11025 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11027 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11028 value from option --iram-size.
11030 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11032 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11035 2002-09-18 <wiml AT hhhh.org>
11037 * SDCClrange.h: exposed setFromRange() and setToRange()
11038 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11039 packRegsForAccUse() (bug 542397)
11040 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11041 multiple times and emitting the fetch operations more than once
11042 added aopGetUsesAcc() function to allow binary operators to
11043 fetch their operands in the correct order; made genMinus() emit
11044 compact code for X = LITERAL - Y
11046 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11047 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11048 sprintf() in line 1267.
11050 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11051 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11054 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11055 Changes to aslink (All the changes are marked with 'JCF'):
11057 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11060 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11061 area BSEG. Also moves, if possible, the DATA area down into the internal
11062 ram so more space is available.
11064 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11067 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11068 not bytes. Function summary() which creates a memory usage summary
11069 file with extension .mem. Reports of overlaping stack and small stack
11070 size. If the space for the stack is less than 16 bytes aslink trows a
11073 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11074 the 8051. Option 'y' for memory summary output file.
11076 Changes to sdcc (All the changes are marked with 'JCF'):
11078 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11080 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11081 overlaying area for it (uses RegBankUsed[4]).
11083 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11084 bank zero as used by default. By default aslink locates the stack
11085 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11086 the creation of the .mem file. Delegates the allocation of data area
11087 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11088 the begining of the stack area to aslink.
11090 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11091 glue() in SDCCglue.c creates an area for it.
11093 2002-09-03 Borut Razem <borut.razem AT siol.net>
11094 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11095 sdcc/src/pic/glue.c:
11096 introduced atexit() handler for teporay files removal in case of
11097 errors, assertions, ...
11099 2002-08-29 Borut Razem <borut.razem AT siol.net>
11100 * sdcc/support/cpp2/auto-host_vc_in.h:
11101 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11102 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11103 Maybe there is a similar problem with BORLANDC? It should be checked!
11105 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11106 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11107 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11108 was not executed, and the compiler (cl) launched a warning:
11109 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11111 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11112 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11114 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11115 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11117 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11118 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11119 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11120 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11121 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11122 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11123 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11124 - added Release configuration in VS projects
11125 - review of compiler an linker options
11126 - VC .exe files are generated in bin_vc directory, not to interfere
11127 with binaries generated from other projects (cygwin, mingw, bcc ...)
11129 * sdcc/src/yacc.dsp: added
11131 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11132 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11133 and insert the version number definitions from .version
11135 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11137 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11138 added - genarate auto-host.h using auto-host_vc_in.h as template
11141 removed from CVS, generated automatically
11143 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11144 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11146 2002-08-11 Borut Razem <borut.razem AT siol.net>
11147 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11149 2002-08-10 Borut Razem <borut.razem AT siol.net>
11150 * src/SDCCmain.c (main):
11151 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11152 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11153 The consequence was that some temporary files were not removed.
11156 unification of code in functions tempfilename() and tempfile():
11157 function tempnam() is defined in Visual Studio 6.0 and .NET
11159 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11161 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11162 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11163 - removed compiler command line option /WX: Treats all warnings as errors
11164 - update a list of source files, included into the project
11166 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11167 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11168 changed project type to Generic Project so that can be correcly converted to VS.NET project

11183 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11184 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11185 - solved MSC error in function aopDump()

11365 Previous fix was not good. basic blocks that have "break" or "return" are
11366 not really partof a loop , but live ranges used in these blocks should

12210 2001-09-03 Michael Hope <michaelh AT juju.net.nz>
12212 * link/z80/aslink.h: Fixed path for PATH_MAX
12214 2001-09-02 Michael Hope <michaelh AT juju.net.nz>
12216 * src/z80/gen.c (fetchLitPair): Changed so that it properly caches direct space references.
12218 * support/regression/tests/addsub.c: Added cases to cover all the +, - combinations.
12220 * support/regression/tests/uminus.c: Added a test for the unary minus operator.
12222 * 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.
12224 2001-09-01 Michael Hope <michaelh AT juju.net.nz>
12226 * src/z80/gen.c: Fixed up generator to pass the regresion tests, specifically fixing loads for longs, genCmp, and turned on the map file.
12227 (genCmp): Fixed up genCmp for the GB with longs.
12229 * device/lib/gbz80/Makefile: Fixed up all the libraries to pass the regression tests.
12231 * support/regression/ports/host/spec.mk: Updated to compile with the new type specifiers.
12233 * device/lib/Makefile.in (Z80SOURCES): Removed old _mululong, _mulslong, and unneeded _mulint.
12235 * device/lib/_mullong.c (_mulslong): Changed to actually return a value :)
12237 2001-08-30 Paul Stoffregen <paul AT pjrc.com>
12239 * added peepholes 223 to 231 to mcs51 port. These improve code when using large model.
12241 2001-08-30 Michael Hope <michaelh AT juju.net.nz>
12243 * 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.
12245 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
12247 2001-08-29 Michael Hope <michaelh AT juju.net.nz>
12249 * link/z80/aslink.h: Fixed long file name support. Is now based off PATH_MAX instead of a constant.
12251 * src/z80/gen.c: Fixed add and sub for the case where left or right are in static space.
