917 Enabled VPATH feature: changed nearly all Makefiles (149 files).
918 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
920 One basic decision: e.g. src/clean.mk includes further files. In order
921 to make this work there are two solutions:
922 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
923 run configure on them. This way they can use
924 'include $(srcdir)/port-clean.mk'
925 - always include clean.mk by the Makefile at the same level. To avoid
926 that `make clean` tries to include and build Makefile.dep the
927 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
928 implemented, because now even `make uninstall` doesn't create
929 Makefile.in. clean.mk could be eliminated by pasting it in
932 * debugger/mcs51/Makefile.in: build own objects from library sources
933 (SLIB, SDCC) in current directory
935 * configure, configure.in: renamed --disable-device-lib-build in
936 --disable-device-lib; added --enable-doc, the required tools are
937 searched by configure; added result message; the toolchain for the

941 the fwk and ports directories don't livet in the build tree using vpath
943 * doc/sdccman.lyx: renamed --disable-device-lib-build to
944 --disable-device-lib, added --enable-doc, added section VPATH
946 * sim/ucsim/configure.in,
947 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
948 z80 are enabled by default

1195 --no-peep and --peep-file <file> are used don't use default rules but
1198 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1200 * src/mcs51/gen.c (genCall): fixed bug 1457608
1202 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1207 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1209 * src/SDCCpeeph.c (operandsLiteral): new, added,

1220 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
1221 implemented patch 1120823 Thanks to Willy De la Court (normal
1222 interrupts need an interrupt number now if they are made critical),
1223 and enabled nesting of critical functions though not for gbz80
1224 (genCritical, genEndCritical): added functions
1225 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1226 * src/z80/mappings.i: added "ei" to all mappings

1231 submitted by the Debian SDCC maintainer Aurelien Jarno:
1232 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1233 archive with gcc 4.1 on mips and wrote the patch"
1235 2006-03-16 Raphael Neider <rneider AT web.de>
1237 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1238 the left operand is shorter than the result (c* = lit-c* + int),
1240 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1243 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1245 * src/.version: increased version number to 2.5.5
1246 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1247 linking is done manually in pic16 port's _linkEdit,
1248 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1249 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1250 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1251 allocate asmop as AOP_ACC,
1252 (aopForRemat): added parameter 'bool result' in function declaration,
1253 (pic16_aopGet): return AOP_ACC when accessing WREG,
1254 (pic16_popGetTempReg): minor modification,

1265 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1266 call to allocReg, not by manually allocating a new one,
1267 (pic16_assignRegisters): now before going through the register
1268 allocating functions mark all registers as free. This eliminates some
1269 side effects resulting from peephole parser done earlier in the backbone
1271 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1273 * src/SDCCicode.c (geniCodeLogic),

1319 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1321 2006-03-06 Borut Razem <borut.razem AT siol.net>
1323 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1324 made the linker quiet
1326 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1328 * src/pic16/gen.c (genPcall): fixed bug #1443644
1329 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1330 which dumps before the function entry point a data byte which represents
1331 the number of the local variables used by the specified function, added
1332 'xinst' for initial support for Extended Instruction Support,
1333 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1334 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1335 port->fun_prefix anymore (may change later),
1336 (genFunction, genEndFunction): do not store/restore local registers for
1337 _main (this should take care the --main-return command line option in
1339 (genOr): removed some legacy pic-port instructions,
1340 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1341 performing operations with SFR's causes data to be written more than
1342 once to each SFR. Perhaps SFRs should be handled in special cases...
1343 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1345 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1346 into account for stack starting position,
1347 (struct OPTIONS pic16_optionsTable): added command line argument
1348 --extended or -y for Extended Instruction Support,
1349 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1350 (deassignLRs): *** perhaps the most important change, old 'for' code
1351 (commented out for reference), didn't account for some registers which

3628 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3629 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3630 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3631 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3632 always available in leading double underscore form. The C99 support is
3633 mostly missing, but it's a start.
3634 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3635 reserved identifier "__data".

3713 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3715 * device/lib/printf_large.c: removed inline assembly for portability and
3716 readability. Use printf_fast if speed or size are more important.
3717 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3718 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3720 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3722 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3723 prevent compiler warning
3725 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3727 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3728 moved to level 0 and declared as static. Also they are explicit
3729 placed in access bank. This was necessery because some times they
3730 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3731 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3732 optimizations. Currently only compare to unsigned char is implemented,
3733 * src/pic16/gen.c: added fReturnIdx array,
3734 * (struct resolvedIfx) is moved to gen.h and made public,
3735 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3736 * (aopForSym): added an optimization to directly store in stack of
3737 the operand of a SEND iCode,
3738 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3739 but as registers instead (AOP_REG) using the fReturnIdx array,
3740 * (pic16_freeAsmop): remove the freed register from the
3741 _G.sregsAlloc field,
3742 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3743 a compare of 'WREG',
3744 * (pic16_popGetTempRegCond): changed function prototype, now
3745 function takes also a bitVector argument v which holds the current
3746 set of registers that are allocated for stack access by aopForSym,
3747 registers allocated in aopForSym for accessing stack symbols are not
3748 any more part of the functions usedRegs field,
3749 * (genCall): some times aopOp is called for a stack variable to be
3750 send, aopForSym might perform the push, if this is true make sure
3751 that genCall doesn't push the variable twice by testing _G.resDirect,
3752 * (genFunction): changed testing for unspecified interrupt number
3753 from 256 to INTNO_UNSPEC,
3754 * modified selection scheme of frame pointer generation. Previously
3755 if function did use local registers a frame pointer was generated,
3756 now a frame pointer is generated only if function has arguments
3757 (that need PLUSW2 register access), or has stack arguments, or the
3758 compiler is not instructed to omit the frame pointer,
3759 * (genEndFunction): before restoring local registers that were saved
3760 in the function preamble, also restore the registers that *might*
3761 have been allocated for stack access,
3762 * (genRet): removed some old comments,
3763 * (genCmp, the active (RN's) version): added a call to the
3764 pic16_genCmp_special function to perform the compare with a more
3765 robust and optimized way,
3766 * (genInline): a feature has been added in inline code generation,
3767 which allows a wildcard variable substitution when writing inline
3768 assembly. Code is incomplete and experimental therefore undocumented,
3769 * (genCast): changed order of aopOp for result and right to allow
3770 aopForSym to directly load the result if possible,
3771 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3772 perform an optimized compare on some selected special occasions,
3773 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3774 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3775 generate an IVT any more,
3776 * src/pic16/main.c (pic16_optionsTable): added command line option
3778 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3779 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3781 * src/pic16/NOTES: Raphael Neider added in list of active developers
3782 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3783 jumptable_end to prevent bug #,
3784 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3785 inCond and outCond fields,
3786 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3787 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3788 turn off register spilling,
3789 * (packRegsForOneUse): synced with other ports' versions although it
3790 is not used currently,
3791 * (pic16_packRegisters): added an optimization while reading
3792 structure bitfields, some registers may be saved (malloc code is
3793 decreased by 80 bytes)
3795 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3797 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3798 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3799 this can be optimized more?
3801 2005-03-10 Raphael Neider <rneider AT web.de>
3803 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3804 genNearPointerGet): (hopefully) fixed access to bitfields via
3805 pointers (p->bitN = x; and x = p->bitN; failed)

3851 to keep the correct label reference count when adding/removing references
3852 to labels. A peephole file using this is appended to patch #1144962.

4439 Adding support for replacing ljmps with sjmps in jumptables
4440 generated for switch statements. For now you need to set the
4441 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4442 Now 4 algorithms for mcs51 jumptable generation are used:
4443 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4444 addresses loaded pc-relative for up to 112 cases and stack-pushing
4445 target addresses loaded with offset from dptr for up to 256 cases.

4475 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4477 * added libc directory. The current version of LibC contains string
4478 functions, ctype functions and macros and some functions of the
4479 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4480 be extensively tested in the future. Standard disclaimer here.
4481 Library is not automatically build yet. But one can build it by
4482 invoking 'make' inside the libc directory.
4483 * added ADC library under libio. Preliminary version yet.

4493 * (pic16_storeForReturn): optimized return of 0,
4494 * (genCmp): experimental code for new genCmp which uses PIC18's
4495 special compare&skip instructions. Initial tests fail some times
4496 with variables grater than 1 byte in size, so new code is disabled,
4497 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4499 * (genCast): began a fix to optimize the casting of a bit to another
4500 bit, now assigning a bitfield to another bitfield will fail, sorry,

4509 and 1 for banking instruction,
4510 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4511 caused stop processing pCodes after a inline assembly block,
4512 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4514 registers when it shouldn't,
4515 * src/pic16/ralloc.c (allocReg): add preliminary support for
4516 supporting a limited set of temporary registers,
4518 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7406 2004-01-27 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7408 * ChangeLog: changed "@" to " AT " in hopes of reducing spam and
7409 virus/worm forged address usage.
7411 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
7413 Fixed promotion, it should be done on AST level:
7414 * src/SDCCast.c (addCast): added promotion to int
7415 (decorateType): updated call to upCast()
7416 * src/SDCCicode.c (geniCodeLeftShift): removed call to
7417 usualUnaryConversions()
7419 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
7421 * support/regression/tests/literalop.c (mulWrapper): Added a
7422 wrapper to remove integer overflow warnings.
7424 * support/regression/tests/float_trans.c: Made work on host.
7426 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
7429 * support/regression/generate-cases.py (main): Changed from inline
7432 * doc/Makefile (install): Changed to depth first to get rid of
7433 missing directory install warning.
7435 * as/Makefile (install-doc): Made work on Mac.
7437 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
7439 * src/SDCCast.c: added an additional type flow in decorateType() of
7440 opposite direction, see feature request #860006; it's enabled at runtime
7441 by setting the environment variable SDCC_NEWTYPEFLOW
7442 * src/SDCCast.h: changed prototype of decorateType()
7443 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
7444 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
7445 'char' to 'int' can be omitted, if both operands are 'unsigned char';
7446 see feature request #877103
7447 * src/SDCCval.c: updated call of decorateType()
7448 (valBitwise): fixed bug #882876
7449 (valMinus): added promotion
7450 (valLogicAndOr): result is unsigned
7451 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
7452 * src/SDCCsymt.c (computeType),
7453 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
7454 must not cause an unsigned operation

7475 * src/pic/ralloc.h: applied patch from Slade Rich;
7476 added support for multiple code pages and multiple RAM banks on the
7477 PIC 14 port. The ASM files now no longer simply assume all the
7478 code / RAM are in the same page / bank. This means the linker can
7479 safely allocate code/RAM of separate ASM files to different pages/banks.
7480 * doc/sdccman.lyx: added Slade's tips
7481 * src/mcs51/peeph.def: fixed bug #880768

7493 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7494 strtof is not part of C89 and isn't included with Mac OS X.
7496 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7498 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7523 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7525 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7526 loaded with the linker search paths (-L arguments) and the libraries
7527 to be linked with the current source (-l arguments). Changes
7528 currently will affect only the pic16 port.
7529 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7530 include path the port specific paths and port specific libraries,
7531 * gplink command now contains the $3 argument,
7532 * src/pic16/device.h,
7533 * src/pic16/device.c,: structure PIC_device is made public and
7534 renamed to PIC16_device, the same for variable Pics which is renamed

7549 Documenting changes from previous commits.
7550 * configure.in (version 1.56),
7551 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7552 when generating output files to configure the pic16 library,
7553 but now I've commented it out, since gputils aren't installed in the
7554 SF compile farm, so library won't compile
7556 * device/lib/Makefile.in (version 1.56): initially I've added in
7557 target 'all' the prerequestive 'model-pic16' so it compiled the
7558 pic16 library, but now I've commented it out for the same reasons
7560 * added targets 'model-pic16' and 'objects-pic16' to compile the
7562 * added target 'port-specific-objects-pic16' to handle the
7563 generated libraries and copy them into the build/ directory
7564 * added target 'clean-intermediate-pic16' to clean intermediate
7565 files into pic16 directory
7566 * in target 'installdirs' added line to create directory pic16 in
7567 the installation path
7569 * device/include/Makefile.in (version 1.11): in target 'install'
7570 added lines to copy all header files to installation path,
7571 * in target 'installdirs' added line create directory for pic16
7572 headers in the installation path

7587 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7588 option so that it actually works. Made it specific to the z80, since
7589 the gbz80 doesn't have these kinds of I/O ports.
7591 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7593 * device/include/z180.h,

7615 Mainly changes to support compilation of the device libraries
7616 * src/pic16/device.c: stack is allocated via symbol and not
7617 via literal number. The symbol is placed in the corresponding
7618 position of the data ram
7619 * (pic16_dump_section): relocatable and absolute uninitialized
7620 data are now emitted in sorted order to reduce section naming,
7621 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7622 weren't marked as being in the access bank,
7624 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7626 Added portion of GNU PIC Library under the directory
7627 device/include/pic16 and device/lib/pic16. These files
7628 contain the declarations of SFRs for the PIC18Fxx2 devices.
7629 The directory is initialized via configure from toplevel.
7631 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7633 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

7659 all over. Telling LaTeX to be less strict with word spacing
7660 to better keep the right margin. Changed some notes about
7661 maintainance of the ports in section 3.2.1 - is it OK like this?
7663 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7703 * src/pic16/peeph.def: all peepholes with movff are commented out,
7704 because there is a problem in the pcode peep optimizer,
7705 * src/pic16/ralloc.c: the register allocator can now reuse local

7770 directive when no overlay data exist
7771 * (picglue): modified to emit uninitialized data segment
7772 according to udata_section_name

7844 Bug reported from Jesus Calvino-Fraga
7846 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7848 * sdcc.spec: updated
7849 * device/include/Makefile.in: don't install CVS directories

7857 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7859 PIC16 port related changes:
7860 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7861 added variable stackPos,
7863 * gen.c: genCall, assignResultValue: added support for
7864 pushing/retrieving function parameters to/from stack,
7865 genFunction,genEndFunction: setup stack frame for the
7867 genAddrOf: will be changed according to bug 863624
7869 * added files genutils.c and genutils.h which contain gen*
7870 debugged and optimised functions extracted from gen.c
7872 * glue.c: added variable 'externs' which holds extern symbols,
7873 pic16emitRegularMap: is modified to properly handle relocatable
7874 symbols under the new scheme,
7875 pic16createInterruptVect: is modified
7876 pic16printPublics: is modified to emit 'global' assembler directives,
7877 added pic16_printExterns to print extern symbols,
7878 pic16glue: initializes stack/frame pointer in the beginning of
7879 the assembly output. Temporary hack, will be corrected later,
7880 because gplink yet does not support stack and SDCC does not
7881 yet support a type of crt0.o object to create the final binary.
7883 * Removed many lines that contain 8051 legacy code.
7884 * The code is finally placed under a 'code' directive.
7885 * Added port specific options.
7887 * _process_pragma: simplified since now we do not need *special*
7888 include file to define SFR registers. But a separate header
7889 will be needed. This will be developed later.
7890 * _pic16_parseOptions: added, parses port specific options:
7891 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7892 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7893 --preplace-udata-with=
7895 * _pic16_setDefaultOptions: modified to initialize section names,
7896 but hack is temporarly out of order since it needs improvement.
7897 * _pic16_genAssemblerPreamble: configuration words are emitted by
7898 their address instead of their name. This part is incomplete and
7899 supports only the 18Fxx2 devices. Other devices will emit an error
7900 during assembly since they do not contain the same set of config
7902 * _pic16_genIVT: is modified,
7904 * pcode.c: added definitions for some hardware registers that are needed
7906 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7907 All PCI entries are updated. Now LFSR is supported.
7908 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7909 * added pic16_newpCodeOpLit2 to support instructions with
7910 two literal arguments
7911 * pic16_pCode2str: corrected code that emits assembler instructions
7912 with two literal operands and those that have an access bit modifier
7913 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7914 this fixes a bug which caused some labels to be lost, when an
7915 assembler directive was added, i.e. banksel,
7916 * pic16_FixRegisterBanking: improved logic that causes the insertion
7918 * InlineFunction: functions that are called once, are not any more
7919 inlined. This can be a port option in the future,
7921 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7923 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7924 hold the corresponding uninitialized symbols,
7925 * pic16_allocProcessorRegister: registers have explicit marked the
7927 * pic16_allocInternalRegister: registers are explicit marked as
7929 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7930 processing list, so bit registers were lost,
7933 * ralloc.h: added field 'accessBank' and original symbol operand
7934 in register definition,
7935 * removed the field isMapped from register definition,
7937 ** Several functions have been removed from various sources:
7938 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7939 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7940 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7941 pic16_assignRelocatableRegisters
7943 ** others have been introduced:
7944 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7945 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7947 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7949 * support/scripts/inc2h.pl: changed definition of BIT_AT
7950 to emit 'sbit at' instead of 'bit at'. This was a request.
7952 PIC16 port related preliminary changes:
7953 * gen.c: prefixed function popRegFromString with
7954 pic16_ and all references to it corrected
7955 * pcode.c: all pic16_pc_* hardware registers prefixed
7956 with underscore (_),
7957 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7958 * ralloc.c: newReg(): when register is REG_SFR then
7959 set address to rIdx,
7960 pic16_allocProcessorRegister(): marks register wasUsed=0
7961 pic16_writeUsedRegs(): added a call to assign processor
7962 registers via pic16_assignFixedRegisters
7964 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7966 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7967 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7968 variables in unused register banks. Also the SSEG is placed
7969 wherever there is enough space for it, and IDATA can be anywhere
7970 in internal RAM. For now compile using -Wl-Y[stack_size].
7971 The mem file is different for this option as well, since it
7972 makes no sense of talking about DSEG lenght.
7974 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7976 * src/SDCClrange.c: fixed bug 869095 that caused segfault

8221 * src/SDCCast.c (decorateType): disabled a transformation I added in
8222 revision 1.188 (access to fields of a structure at an absolute address);
8223 it breaks with bitfields, extern declarations, and gcse analysis.
8224 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8225 could be assigned through a pointer, so don't complain.

8333 xdata initialization slightly shorter
8335 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8889 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8890 refer to the const or volatile state of the pointer itself.

9003 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9004 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9005 type for bits was changed. It resulted in bit variables becoming
9006 global, which is not permitted in PIC 14 assembly output.

9023 A few small changes that speed up the peephole optimizer.
9027 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9029 Try to make the peephole optimizer smarter by maintaining
9030 an association between the assembly source code and the
9031 iCodes that originated them. Put this information to use
9032 with a new peephole rule condition "notVolatile" so that
9033 the rules can be aggressive yet still safe.
9038 * src/mcs51/peeph.def
9040 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9044 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

9046 if the left or right operand symbols have the accuse flag set.
9048 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9050 Changed the type of the result of the ! (NOT) operator to char;
9051 previously it returned the same type as the source. This allows
9052 us to eliminate all the genFloatNot functions (all of its target
9053 implementations were very buggy) since !float can use the same

9065 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9066 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9067 during interrupts. Ensure WSAVE is located at a shared bank address.
9068 2. Fixed page selection in some places
9069 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9070 the registers name strings.
9071 4. Fixed "signed / unsigned compare" compiler warnings.
9072 5. The PIC port manages its own allocation of the general purpose
9073 registers, but makes no attempt to reuse them. As a result when
9074 compiling it soon runs out of general purpose registers. Some
9075 additional code was added to the files pcode.c and device.c to walk
9076 through the function call tree and rename the registers so that they
9086 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

9093 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9095 Made bitfield a distinct type from bit so that bitfields
9096 convert as per ANSI C and bits retain their traditional
9097 boolean style behaviour. Implemented bitfield support in
9105 * src/ds390/gen.c: bit v bitfield split
9106 * src/z80/gen.c: New support for bitfields
9107 * support/regression/tests/bitfields.c: reenabled z80,
9110 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9112 Rules 246.x, 247.x relate to bitfields, the others speed up
9113 access to xdata mapped I/O devices.
9115 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9117 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9119 Cleaned up genPackBits and genUnpackBits and added two helper
9120 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9121 for literal assignments in genPackBits (thanks to Frieder for
9127 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9129 Fixed bug #748310 (pointer to function type mishandled when the
9130 function name is omitted). Also fixed a SIGSEGV when a function
9131 attribute (reentrant, etc) is used on a non-function or on a
9132 function but misplaced before the parameter list.
9134 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9136 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9137 * support/Util/SDCCerr.h,

9159 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9161 Made the constant following the "interrupt" keyword optional. If
9162 omitted, the function will not automatically be given an entry
9163 in the interrupt vector table (similar to #pragma NOIV, but
9164 less syntacticly kludgy). The interrupt number is also now
9165 range checked. Also fixed a bug in the high order bit example

9179 * src/SDCCicode.c (operandOperation): rewritten some ops
9180 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9181 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9183 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9184 be re-activated by defining REDUCE_LITERALS)
9185 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9186 unsigned, but are signed by default
9187 * src/SDCCval.c (constVal): rearranged
9188 * src/SDCCval.c (valMod): preliminary fix
9189 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9231 constants are unsigned; added recognition of "u" flag for unsigned
9232 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9233 * src/SDCCval.c (valDiv, valMod): fixed signdness
9234 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9235 signedness of modulo, left and right shift

9694 * src/SDCCmain.c: linkOptions is changed to set *,
9695 added if/endif conditional macros to remove options help
9696 messages from optionsTable when a port is not configured, added
9697 support for the PIc16 port in the ports table, when executing
9698 the compiler with no port specified on command line, a default
9699 port is selected with the new macro DEFAULT_PORT which is
9700 defined in port.h, in setDefaultOptions() linkOptions is removed
9701 from initialization assignment, since now it is a set,
9702 parseCmdLine uses setParseWithComma for linkOptions, in
9703 linkEdit() linkOptions are accessed with new function indexSet()
9704 which returns the i'th item of a set variable. See SDCCset.c, in
9705 linkEdit() when calling buildCmdLine(), added linkOptions as
9706 last argument. Now users can pass arguments to gplink via the
9707 -Wl option, main() uses pic16glue() to glue up pic16 programs

9719 * src/pic16/glue.c: commented out some error producing lines
9720 * src/pic16/main.c: __config directives are commented out to stop
9721 gpasm complaining and test the linkage with gplink, _linkCmd and
9722 _asmCmd changed to be more gplink and gpasm friendly
9723 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9724 produced an error when parsed, peep rule 12 is added to utilize
9725 movff, but it is commented out since the pCode does not support
9726 yet a command with 2 address arguments
9728 2003-05-18 <johan AT balder>
9730 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9757 2003-05-11 Borut Razem <borut.razem AT siol.net>
9759 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9760 the path of bin directory, so that PATH is the only env. variable, which has to be set
9761 in case of standard installation.

10788 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10789 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10791 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10793 * in /sdcc/as/mcs51/ changed these files in order to create an
10794 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10795 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10796 following files to include the previous two files: aslink.dsp,
10797 Makefile.aslink, Makefile.bcc, and Makefile.in.
10799 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
10800 .adb instead of .cdb
10802 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10804 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
10805 value from option --iram-size.
10807 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10809 * /sdcc/as/mcs51/lklist.c: added boundary check before using
10812 2002-09-18 <wiml AT hhhh.org>
10814 * SDCClrange.h: exposed setFromRange() and setToRange()
10815 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10816 packRegsForAccUse() (bug 542397)
10817 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10818 multiple times and emitting the fetch operations more than once
10819 added aopGetUsesAcc() function to allow binary operators to
10820 fetch their operands in the correct order; made genMinus() emit
10821 compact code for X = LITERAL - Y
10823 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10824 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
10825 sprintf() in line 1267.
10827 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10828 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10831 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10832 Changes to aslink (All the changes are marked with 'JCF'):
10834 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
10837 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
10838 area BSEG. Also moves, if possible, the DATA area down into the internal
10839 ram so more space is available.
10841 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
10844 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
10845 not bytes. Function summary() which creates a memory usage summary
10846 file with extension .mem. Reports of overlaping stack and small stack
10847 size. If the space for the stack is less than 16 bytes aslink trows a
10850 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
10851 the 8051. Option 'y' for memory summary output file.
10853 Changes to sdcc (All the changes are marked with 'JCF'):
10855 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
10857 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
10858 overlaying area for it (uses RegBankUsed[4]).
10860 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
10861 bank zero as used by default. By default aslink locates the stack
10862 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10863 the creation of the .mem file. Delegates the allocation of data area
10864 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10865 the begining of the stack area to aslink.
10867 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
10868 glue() in SDCCglue.c creates an area for it.
10870 2002-09-03 Borut Razem <borut.razem AT siol.net>
10871 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10872 sdcc/src/pic/glue.c:
10873 introduced atexit() handler for teporay files removal in case of
10874 errors, assertions, ...
10876 2002-08-29 Borut Razem <borut.razem AT siol.net>
10877 * sdcc/support/cpp2/auto-host_vc_in.h:
10878 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10879 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10880 Maybe there is a similar problem with BORLANDC? It should be checked!
10882 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10883 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10884 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10885 was not executed, and the compiler (cl) launched a warning:
10886 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10888 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10889 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10891 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10892 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10894 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10895 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10896 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10897 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10898 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10899 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10900 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10901 - added Release configuration in VS projects
10902 - review of compiler an linker options
10903 - VC .exe files are generated in bin_vc directory, not to interfere
10904 with binaries generated from other projects (cygwin, mingw, bcc ...)
10906 * sdcc/src/yacc.dsp: added
10908 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10909 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10910 and insert the version number definitions from .version
10912 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10914 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10915 added - genarate auto-host.h using auto-host_vc_in.h as template
10918 removed from CVS, generated automatically
10920 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10921 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10923 2002-08-11 Borut Razem <borut.razem AT siol.net>
10924 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10926 2002-08-10 Borut Razem <borut.razem AT siol.net>
10927 * src/SDCCmain.c (main):
10928 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10929 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10930 The consequence was that some temporary files were not removed.
10933 unification of code in functions tempfilename() and tempfile():
10934 function tempnam() is defined in Visual Studio 6.0 and .NET
10936 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10938 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10939 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10940 - removed compiler command line option /WX: Treats all warnings as errors
10941 - update a list of source files, included into the project
10943 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10944 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10945 changed project type to Generic Project so that can be correcly converted to VS.NET project
10947 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10949 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10951 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10953 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10954 added return 0 statements after assert() to make compiler happy
10956 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10957 added newline in the def file to keep MSC compiler satisfied
10959 * sdcc/src/z80/gen.c:
10960 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10961 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10962 - solved MSC error in function aopDump()
10964 * sdcc_vc.h: define PREFIX as "\\sdcc"
10966 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10967 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
10969 2002-06-22 Scott Dattalo <scott AT dattalo.com>
10970 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10971 - Rewrote the register banking algorithm.
10972 - Added pCode live-range analysis to registers (for now, only non-used and
10973 singly-used registers optimized away)
10975 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10977 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

11002 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11004 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11006 2002-03-28 Johan Knol <johan AT balder>
11008 * src/SDCCval.c: fixed bug #532436
11010 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11012 Added "char *Processor" field to the port structure.
11015 Added -p option. Allows port dependent processor to be specified.
11018 Initialized the new field char *Processor field to NULL in all ports
11021 Compiler generated registers for interrupt context saving
11022 were not getting allocated.
11024 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11027 Fixed left shift. Will promote the left side of a left shift
11028 if a) left shifting more than size of operand or b) when assigned
11029 to something size > size of left side
11031 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11035 analysis is restructured. ...
11037 * src/pic/device.h:
11040 * src/pic/device.c:
11041 Added. device.c is a PIC port hack to accomodate variations
11044 2002-03-13 Michael Hope <michaelh AT vroom>
11046 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11048 2002-03-04 johanknol <johanknol AT manik>
11050 * /src/SDCCval.c: fixed
11052 const unsigned char arr[][2] = { { 0, 1 } };

11139 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11141 * sdcc/src/SDCCloop.c:
11142 Previous fix was not good. basic blocks that have "break" or "return" are
11143 not really partof a loop , but live ranges used in these blocks should
11144 be live thru the entire loop, so set partOfLoop but don't add them to
11147 2002-02-21 <johan AT FRIJA>
11149 * src/SDCCcse.c: fixed bug #514308
11151 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11154 Fixed BUG #519583. If a conditional block ended in a return/break
