882 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
884 Enabled VPATH feature: changed nearly all Makefiles (149 files).
885 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
887 One basic decision: e.g. src/clean.mk includes further files. In order
888 to make this work there are two solutions:
889 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
890 run configure on them. This way they can use
891 'include $(srcdir)/port-clean.mk'
892 - always include clean.mk by the Makefile at the same level. To avoid
893 that `make clean` tries to include and build Makefile.dep the
894 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
895 implemented, because now even `make uninstall` doesn't create
896 Makefile.in. clean.mk could be eliminated by pasting it in
899 * debugger/mcs51/Makefile.in: build own objects from library sources
900 (SLIB, SDCC) in current directory
902 * configure, configure.in: renamed --disable-device-lib-build in
903 --disable-device-lib; added --enable-doc, the required tools are
904 searched by configure; added result message; the toolchain for the
905 belonging ports are now only built, if the port is enabled.
907 * support/regression/*: all output is written in directory gen, because
908 the fwk and ports directories don't livet in the build tree using vpath
910 * doc/sdccman.lyx: renamed --disable-device-lib-build to
911 --disable-device-lib, added --enable-doc, added section VPATH
913 * sim/ucsim/configure.in,
914 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
915 z80 are enabled by default
917 2006-04-24 Raphael Neider <rneider AT web.de>
919 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
920 to config word, "pic14_"-prefixed some extern functions
921 (pic14_emitConfigWord): emit __config directive(s) if assignment to
922 config word has been found
923 * src/pic/device.h: added prototypes
924 * src/pic/pcode.c: added "pic14_"-prefix where needed
925 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
927 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
929 (pic14emitRegularMap): ignore config words,
930 (pic14createInterruptVect): moved generating __config directives away
931 (picglue): have __config directives emitted
933 2006-04-24 Borut Razem <borut.razem AT siol.net>
935 * doc/Makefile: sync with nightly build makefile
937 2006-04-24 Raphael Neider <rneider AT web.de>

1189 interrupts need an interrupt number now if they are made critical),
1190 and enabled nesting of critical functions though not for gbz80
1191 (genCritical, genEndCritical): added functions
1192 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1193 * src/z80/mappings.i: added "ei" to all mappings

1205 the left operand is shorter than the result (c* = lit-c* + int),
1207 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1210 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1212 * src/.version: increased version number to 2.5.5
1213 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1214 linking is done manually in pic16 port's _linkEdit,
1215 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1216 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1217 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1218 allocate asmop as AOP_ACC,
1219 (aopForRemat): added parameter 'bool result' in function declaration,
1220 (pic16_aopGet): return AOP_ACC when accessing WREG,
1221 (pic16_popGetTempReg): minor modification,

1232 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1233 call to allocReg, not by manually allocating a new one,
1234 (pic16_assignRegisters): now before going through the register
1235 allocating functions mark all registers as free. This eliminates some
1236 side effects resulting from peephole parser done earlier in the backbone
1238 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1296 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1297 which dumps before the function entry point a data byte which represents
1298 the number of the local variables used by the specified function, added
1299 'xinst' for initial support for Extended Instruction Support,
1300 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1301 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1302 port->fun_prefix anymore (may change later),
1303 (genFunction, genEndFunction): do not store/restore local registers for
1304 _main (this should take care the --main-return command line option in
1306 (genOr): removed some legacy pic-port instructions,
1307 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1308 performing operations with SFR's causes data to be written more than
1309 once to each SFR. Perhaps SFRs should be handled in special cases...
1310 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1312 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1313 into account for stack starting position,

1315 --extended or -y for Extended Instruction Support,
1316 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1317 (deassignLRs): *** perhaps the most important change, old 'for' code
1318 (commented out for reference), didn't account for some registers which
1319 were left marked 'not free' after a pointer operation. The change
1320 reduces register usage a lot in some cases
1322 2006-03-04 Borut Razem <borut.razem AT siol.net>
1324 * support/regression/ports/hc08/spec.mk: remove *.asm in traget

3593 * src/SDCCglobal.h (struct options),
3595 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3596 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3597 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3598 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3599 always available in leading double underscore form. The C99 support is
3600 mostly missing, but it's a start.
3601 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3602 reserved identifier "__data".
3604 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

3680 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3682 * device/lib/printf_large.c: removed inline assembly for portability and
3683 readability. Use printf_fast if speed or size are more important.
3684 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3685 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3687 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3689 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3690 prevent compiler warning
3692 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3694 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3695 moved to level 0 and declared as static. Also they are explicit
3696 placed in access bank. This was necessery because some times they
3697 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3698 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3699 optimizations. Currently only compare to unsigned char is implemented,
3700 * src/pic16/gen.c: added fReturnIdx array,
3701 * (struct resolvedIfx) is moved to gen.h and made public,
3702 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3703 * (aopForSym): added an optimization to directly store in stack of
3704 the operand of a SEND iCode,
3705 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3706 but as registers instead (AOP_REG) using the fReturnIdx array,
3707 * (pic16_freeAsmop): remove the freed register from the
3708 _G.sregsAlloc field,
3709 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3710 a compare of 'WREG',
3711 * (pic16_popGetTempRegCond): changed function prototype, now
3712 function takes also a bitVector argument v which holds the current
3713 set of registers that are allocated for stack access by aopForSym,
3714 registers allocated in aopForSym for accessing stack symbols are not
3715 any more part of the functions usedRegs field,
3716 * (genCall): some times aopOp is called for a stack variable to be
3717 send, aopForSym might perform the push, if this is true make sure
3718 that genCall doesn't push the variable twice by testing _G.resDirect,
3719 * (genFunction): changed testing for unspecified interrupt number
3720 from 256 to INTNO_UNSPEC,
3721 * modified selection scheme of frame pointer generation. Previously
3722 if function did use local registers a frame pointer was generated,
3723 now a frame pointer is generated only if function has arguments
3724 (that need PLUSW2 register access), or has stack arguments, or the
3725 compiler is not instructed to omit the frame pointer,
3726 * (genEndFunction): before restoring local registers that were saved
3727 in the function preamble, also restore the registers that *might*
3728 have been allocated for stack access,
3729 * (genRet): removed some old comments,
3730 * (genCmp, the active (RN's) version): added a call to the
3731 pic16_genCmp_special function to perform the compare with a more
3732 robust and optimized way,
3733 * (genInline): a feature has been added in inline code generation,
3734 which allows a wildcard variable substitution when writing inline
3735 assembly. Code is incomplete and experimental therefore undocumented,
3736 * (genCast): changed order of aopOp for result and right to allow
3737 aopForSym to directly load the result if possible,
3738 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3739 perform an optimized compare on some selected special occasions,
3740 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3741 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3742 generate an IVT any more,
3743 * src/pic16/main.c (pic16_optionsTable): added command line option
3745 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3746 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3748 * src/pic16/NOTES: Raphael Neider added in list of active developers
3749 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3750 jumptable_end to prevent bug #,
3751 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3752 inCond and outCond fields,
3753 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3754 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3755 turn off register spilling,
3756 * (packRegsForOneUse): synced with other ports' versions although it
3757 is not used currently,
3758 * (pic16_packRegisters): added an optimization while reading
3759 structure bitfields, some registers may be saved (malloc code is
3760 decreased by 80 bytes)
3762 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3764 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3765 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3766 this can be optimized more?
3768 2005-03-10 Raphael Neider <rneider AT web.de>
3770 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3771 genNearPointerGet): (hopefully) fixed access to bitfields via
3772 pointers (p->bitN = x; and x = p->bitN; failed)
3774 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3818 to keep the correct label reference count when adding/removing references
3819 to labels. A peephole file using this is appended to patch #1144962.

4406 Adding support for replacing ljmps with sjmps in jumptables
4407 generated for switch statements. For now you need to set the
4408 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4409 Now 4 algorithms for mcs51 jumptable generation are used:
4410 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4411 addresses loaded pc-relative for up to 112 cases and stack-pushing
4412 target addresses loaded with offset from dptr for up to 256 cases.

4439 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4440 to call when a stack overflow occurs,
4441 * (malloc.h): added CVS Id tag,
4442 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4444 * added libc directory. The current version of LibC contains string
4445 functions, ctype functions and macros and some functions of the
4446 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4447 be extensively tested in the future. Standard disclaimer here.
4448 Library is not automatically build yet. But one can build it by
4449 invoking 'make' inside the libc directory.
4450 * added ADC library under libio. Preliminary version yet.
4452 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

4459 * (genUminusFloat): fixed for pic16, ported code from mcs51,
4460 * (pic16_storeForReturn): optimized return of 0,
4461 * (genCmp): experimental code for new genCmp which uses PIC18's
4462 special compare&skip instructions. Initial tests fail some times
4463 with variables grater than 1 byte in size, so new code is disabled,
4464 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4466 * (genCast): began a fix to optimize the casting of a bit to another
4467 bit, now assigning a bitfield to another bitfield will fail, sorry,
4468 * src/pic16/main.c: disabled the use of lr-support feature,
4469 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4472 bits with offset (case PO_GPR_BIT),
4473 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4475 * (isBankInstruction): modified to return 0 for no banking instruction,
4476 and 1 for banking instruction,
4477 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4478 caused stop processing pCodes after a inline assembly block,
4479 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4480 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4481 registers when it shouldn't,
4482 * src/pic16/ralloc.c (allocReg): add preliminary support for
4483 supporting a limited set of temporary registers,
4485 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4487 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4488 genDataPointerSet): ensure assignments always copy in MSB to LSB
4490 (loadRegFromAop): recognize CLRH optimization,
4491 (genFunction): optimize RECEIVE iCodes in reentrant functions
4493 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4495 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7422 * src/pic/glue (pic14emitRegularMap),
7423 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
7425 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
7427 * src/pic/pcode.c (PCodeID): commented out left over debug code
7429 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
7431 * support/valdiag/tests/overflow.c: added shift tests
7439 * src/pic/pcodepeep.c,
7440 * src/pic/pcoderegs.c,
7442 * src/pic/ralloc.h: applied patch from Slade Rich;
7443 added support for multiple code pages and multiple RAM banks on the
7444 PIC 14 port. The ASM files now no longer simply assume all the
7445 code / RAM are in the same page / bank. This means the linker can
7446 safely allocate code/RAM of separate ASM files to different pages/banks.
7447 * doc/sdccman.lyx: added Slade's tips
7448 * src/mcs51/peeph.def: fixed bug #880768

7457 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
7460 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
7461 strtof is not part of C89 and isn't included with Mac OS X.
7463 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7465 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

7490 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7492 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7493 loaded with the linker search paths (-L arguments) and the libraries
7494 to be linked with the current source (-l arguments). Changes
7495 currently will affect only the pic16 port.
7496 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7497 include path the port specific paths and port specific libraries,
7498 * gplink command now contains the $3 argument,
7499 * src/pic16/device.h,
7500 * src/pic16/device.c,: structure PIC_device is made public and
7501 renamed to PIC16_device, the same for variable Pics which is renamed
7502 to Pics16. Updated all references to them.
7503 * src/pic16/glue.c (pic16glue): corrected bug with code
7504 initialization which bypassed the variable initializations block.

7516 Documenting changes from previous commits.
7517 * configure.in (version 1.56),
7518 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7519 when generating output files to configure the pic16 library,
7520 but now I've commented it out, since gputils aren't installed in the
7521 SF compile farm, so library won't compile
7523 * device/lib/Makefile.in (version 1.56): initially I've added in
7524 target 'all' the prerequestive 'model-pic16' so it compiled the
7525 pic16 library, but now I've commented it out for the same reasons
7527 * added targets 'model-pic16' and 'objects-pic16' to compile the
7529 * added target 'port-specific-objects-pic16' to handle the
7530 generated libraries and copy them into the build/ directory
7531 * added target 'clean-intermediate-pic16' to clean intermediate
7532 files into pic16 directory
7533 * in target 'installdirs' added line to create directory pic16 in
7534 the installation path

7537 added lines to copy all header files to installation path,
7538 * in target 'installdirs' added line create directory for pic16
7539 headers in the installation path

7554 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7555 option so that it actually works. Made it specific to the z80, since
7556 the gbz80 doesn't have these kinds of I/O ports.
7558 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7560 * device/include/z180.h,

7582 Mainly changes to support compilation of the device libraries
7583 * src/pic16/device.c: stack is allocated via symbol and not
7584 via literal number. The symbol is placed in the corresponding
7585 position of the data ram
7586 * (pic16_dump_section): relocatable and absolute uninitialized
7587 data are now emitted in sorted order to reduce section naming,
7588 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7589 weren't marked as being in the access bank,
7591 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7593 Added portion of GNU PIC Library under the directory
7594 device/include/pic16 and device/lib/pic16. These files
7595 contain the declarations of SFRs for the PIC18Fxx2 devices.
7596 The directory is initialized via configure from toplevel.
7598 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
7600 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

7626 all over. Telling LaTeX to be less strict with word spacing
7627 to better keep the right margin. Changed some notes about
7628 maintainance of the ports in section 3.2.1 - is it OK like this?
7630 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7668 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
7670 * src/pic16/peeph.def: all peepholes with movff are commented out,
7671 because there is a problem in the pcode peep optimizer,
7672 * src/pic16/ralloc.c: the register allocator can now reuse local

7824 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7826 PIC16 port related changes:
7827 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7828 added variable stackPos,
7830 * gen.c: genCall, assignResultValue: added support for
7831 pushing/retrieving function parameters to/from stack,
7832 genFunction,genEndFunction: setup stack frame for the
7834 genAddrOf: will be changed according to bug 863624
7836 * added files genutils.c and genutils.h which contain gen*
7837 debugged and optimised functions extracted from gen.c
7839 * glue.c: added variable 'externs' which holds extern symbols,
7840 pic16emitRegularMap: is modified to properly handle relocatable
7841 symbols under the new scheme,
7842 pic16createInterruptVect: is modified
7843 pic16printPublics: is modified to emit 'global' assembler directives,
7844 added pic16_printExterns to print extern symbols,
7845 pic16glue: initializes stack/frame pointer in the beginning of
7846 the assembly output. Temporary hack, will be corrected later,
7847 because gplink yet does not support stack and SDCC does not
7848 yet support a type of crt0.o object to create the final binary.
7850 * Removed many lines that contain 8051 legacy code.
7851 * The code is finally placed under a 'code' directive.
7852 * Added port specific options.
7854 * _process_pragma: simplified since now we do not need *special*
7855 include file to define SFR registers. But a separate header
7856 will be needed. This will be developed later.
7857 * _pic16_parseOptions: added, parses port specific options:
7858 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7859 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7860 --preplace-udata-with=
7862 * _pic16_setDefaultOptions: modified to initialize section names,
7863 but hack is temporarly out of order since it needs improvement.
7864 * _pic16_genAssemblerPreamble: configuration words are emitted by
7865 their address instead of their name. This part is incomplete and
7866 supports only the 18Fxx2 devices. Other devices will emit an error
7867 during assembly since they do not contain the same set of config
7869 * _pic16_genIVT: is modified,
7871 * pcode.c: added definitions for some hardware registers that are needed
7873 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7874 All PCI entries are updated. Now LFSR is supported.
7875 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7876 * added pic16_newpCodeOpLit2 to support instructions with
7877 two literal arguments
7878 * pic16_pCode2str: corrected code that emits assembler instructions
7879 with two literal operands and those that have an access bit modifier
7880 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7881 this fixes a bug which caused some labels to be lost, when an
7882 assembler directive was added, i.e. banksel,
7883 * pic16_FixRegisterBanking: improved logic that causes the insertion
7885 * InlineFunction: functions that are called once, are not any more
7886 inlined. This can be a port option in the future,
7888 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7890 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7891 hold the corresponding uninitialized symbols,
7892 * pic16_allocProcessorRegister: registers have explicit marked the
7894 * pic16_allocInternalRegister: registers are explicit marked as
7896 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7897 processing list, so bit registers were lost,
7900 * ralloc.h: added field 'accessBank' and original symbol operand
7901 in register definition,
7902 * removed the field isMapped from register definition,
7904 ** Several functions have been removed from various sources:
7905 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7906 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7907 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7908 pic16_assignRelocatableRegisters
7910 ** others have been introduced:
7911 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7912 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7914 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7916 * support/scripts/inc2h.pl: changed definition of BIT_AT
7917 to emit 'sbit at' instead of 'bit at'. This was a request.
7919 PIC16 port related preliminary changes:
7920 * gen.c: prefixed function popRegFromString with
7921 pic16_ and all references to it corrected
7922 * pcode.c: all pic16_pc_* hardware registers prefixed
7923 with underscore (_),
7924 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7925 * ralloc.c: newReg(): when register is REG_SFR then
7926 set address to rIdx,
7927 pic16_allocProcessorRegister(): marks register wasUsed=0
7928 pic16_writeUsedRegs(): added a call to assign processor
7929 registers via pic16_assignFixedRegisters
7931 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7933 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7934 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7935 variables in unused register banks. Also the SSEG is placed
7936 wherever there is enough space for it, and IDATA can be anywhere
7937 in internal RAM. For now compile using -Wl-Y[stack_size].
7938 The mem file is different for this option as well, since it
7939 makes no sense of talking about DSEG lenght.
7941 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7943 * src/SDCClrange.c: fixed bug 869095 that caused segfault

8188 * src/SDCCast.c (decorateType): disabled a transformation I added in
8189 revision 1.188 (access to fields of a structure at an absolute address);
8190 it breaks with bitfields, extern declarations, and gcse analysis.
8191 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8192 could be assigned through a pointer, so don't complain.

8916 reported in bug #800609
8918 2003-09-04 Vangelis Rokas <vrokas AT otenet.gr>
8920 * Top header beautifications in src/pic16 directory:
8921 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
8922 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
8923 pcoderegs.h, ralloc.c, ralloc.h
8924 * main.c: added top header and GPL license notice
8925 * pcode.c: fixed the if-conditional warning
8927 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
8929 * device/lib/_mullong.c: replaced int by short for gcc
8931 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8933 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
8934 and JUMPTABLE iCodes properly now (worked by accident before)
8935 * src/mcs51/gen.c (leftRightUseAcc),
8936 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
8937 iCode properly now. Use getSize instead of nRegs since a & b
8938 aren't part of the nRegs tally.
8940 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
8942 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
8943 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
8944 before instructions that use the _STATUS register
8946 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
8948 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8949 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8950 fetching of the pointer
8951 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8952 copied from genNearPointerSet()
8953 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8954 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
8955 If they pop r0/r1 they must be called in the opposite order than aopOp().
8956 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
8957 (resp. --stack-auto), prepared for --xstack
8959 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

8963 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8965 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
8966 these ports have their own __sdcc_external_start()
8968 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
8970 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8971 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8972 type for bits was changed. It resulted in bit variables becoming
8973 global, which is not permitted in PIC 14 assembly output.
8975 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8977 * doc/sdccman.lyx: various additions and updates. Rearranged sections
8979 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8981 Z80 and MCS51 linkers complaint if a public symbol is defined
8982 in more than one library module:
8986 * as/mcs51/Makefile.in
8988 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8990 A few small changes that speed up the peephole optimizer.
8994 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8996 Try to make the peephole optimizer smarter by maintaining
8997 an association between the assembly source code and the
8998 iCodes that originated them. Put this information to use
8999 with a new peephole rule condition "notVolatile" so that
9000 the rules can be aggressive yet still safe.
9005 * src/mcs51/peeph.def
9007 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9011 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9012 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9013 if the left or right operand symbols have the accuse flag set.
9015 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9017 Changed the type of the result of the ! (NOT) operator to char;
9018 previously it returned the same type as the source. This allows
9019 us to eliminate all the genFloatNot functions (all of its target
9020 implementations were very buggy) since !float can use the same
9023 * src/SDCCicode.c (ast2iCode): ! returns char
9024 * src/mcs51/gen.c (genNot, genNotFloat),
9025 * src/ds390/gen.c (genNot, genNotFloat),
9026 * src/z80/gen.c (genNot, genNotFloat),
9027 * src/pic/gen.c (genNot, genNotFloat),
9028 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9030 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9032 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9033 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9034 during interrupts. Ensure WSAVE is located at a shared bank address.
9035 2. Fixed page selection in some places
9036 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9037 the registers name strings.
9038 4. Fixed "signed / unsigned compare" compiler warnings.
9039 5. The PIC port manages its own allocation of the general purpose
9040 registers, but makes no attempt to reuse them. As a result when
9041 compiling it soon runs out of general purpose registers. Some
9042 additional code was added to the files pcode.c and device.c to walk
9043 through the function call tree and rename the registers so that they
9053 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9054 genPlus() & genMinus() when the result is the same as left or right

9060 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9062 Made bitfield a distinct type from bit so that bitfields
9063 convert as per ANSI C and bits retain their traditional
9064 boolean style behaviour. Implemented bitfield support in
9072 * src/ds390/gen.c: bit v bitfield split
9073 * src/z80/gen.c: New support for bitfields
9074 * support/regression/tests/bitfields.c: reenabled z80,
9077 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9079 Rules 246.x, 247.x relate to bitfields, the others speed up
9080 access to xdata mapped I/O devices.
9082 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9084 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9086 Cleaned up genPackBits and genUnpackBits and added two helper
9087 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9088 for literal assignments in genPackBits (thanks to Frieder for
9094 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9096 Fixed bug #748310 (pointer to function type mishandled when the
9097 function name is omitted). Also fixed a SIGSEGV when a function
9098 attribute (reentrant, etc) is used on a non-function or on a
9099 function but misplaced before the parameter list.
9101 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9103 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9104 * support/Util/SDCCerr.h,

9126 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9128 Made the constant following the "interrupt" keyword optional. If
9129 omitted, the function will not automatically be given an entry
9130 in the interrupt vector table (similar to #pragma NOIV, but
9131 less syntacticly kludgy). The interrupt number is also now
9132 range checked. Also fixed a bug in the high order bit example
9139 * support/Util/SDCCerr.c
9140 * support/Util/SDCCerr.h
9143 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

9146 * src/SDCCicode.c (operandOperation): rewritten some ops
9147 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9148 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9150 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9151 be re-activated by defining REDUCE_LITERALS)
9152 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9153 unsigned, but are signed by default
9154 * src/SDCCval.c (constVal): rearranged
9155 * src/SDCCval.c (valMod): preliminary fix
9156 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9199 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9200 * src/SDCCval.c (valDiv, valMod): fixed signdness
9201 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9202 signedness of modulo, left and right shift

9608 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
9609 the regression tests I'm not brave enough to enable 245.b, 245.c
9610 * doc/sdccman.lyx: added latex preamble for hyperref package.
9611 Using pdflatex this will give you a hyperlinked pdf file with
9612 bookmarks. (prepend '%' before /usepackage if this breaks something)

9650 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9652 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9653 it can be defined with CFLAGS when running configure
9654 * src/SDCCmain.c: fixed compiling + linking with object files
9656 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

9659 added --disable-pic16-port
9660 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9661 * src/SDCCmain.c: linkOptions is changed to set *,
9662 added if/endif conditional macros to remove options help
9663 messages from optionsTable when a port is not configured, added
9664 support for the PIc16 port in the ports table, when executing
9665 the compiler with no port specified on command line, a default
9666 port is selected with the new macro DEFAULT_PORT which is
9667 defined in port.h, in setDefaultOptions() linkOptions is removed
9668 from initialization assignment, since now it is a set,
9669 parseCmdLine uses setParseWithComma for linkOptions, in
9670 linkEdit() linkOptions are accessed with new function indexSet()
9671 which returns the i'th item of a set variable. See SDCCset.c, in
9672 linkEdit() when calling buildCmdLine(), added linkOptions as
9673 last argument. Now users can pass arguments to gplink via the
9674 -Wl option, main() uses pic16glue() to glue up pic16 programs

9686 * src/pic16/glue.c: commented out some error producing lines
9687 * src/pic16/main.c: __config directives are commented out to stop
9688 gpasm complaining and test the linkage with gplink, _linkCmd and
9689 _asmCmd changed to be more gplink and gpasm friendly
9690 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9691 produced an error when parsed, peep rule 12 is added to utilize
9692 movff, but it is commented out since the pCode does not support
9693 yet a command with 2 address arguments
9695 2003-05-18 <johan AT balder>
9697 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9698 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9724 2003-05-11 Borut Razem <borut.razem AT siol.net>
9726 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9727 the path of bin directory, so that PATH is the only env. variable, which has to be set
9728 in case of standard installation.

10801 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10804 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10805 area BSEG. Also moves, if possible, the DATA area down into the internal
10806 ram so more space is available.
10808 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10811 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10812 not bytes. Function summary() which creates a memory usage summary
10813 file with extension .mem. Reports of overlaping stack and small stack
10814 size. If the space for the stack is less than 16 bytes aslink trows a
10817 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10818 the 8051. Option 'y' for memory summary output file.
10820 Changes to sdcc (All the changes are marked with 'JCF'):
10822 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10824 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10825 overlaying area for it (uses RegBankUsed[4]).
10827 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10828 bank zero as used by default. By default aslink locates the stack
10829 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10830 the creation of the .mem file. Delegates the allocation of data area
10831 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10832 the begining of the stack area to aslink.
10834 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10835 glue() in SDCCglue.c creates an area for it.
10837 2002-09-03 Borut Razem <borut.razem AT siol.net>
10838 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10839 sdcc/src/pic/glue.c:
10840 introduced atexit() handler for teporay files removal in case of
10841 errors, assertions, ...
10843 2002-08-29 Borut Razem <borut.razem AT siol.net>
10844 * sdcc/support/cpp2/auto-host_vc_in.h:
10845 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10846 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10847 Maybe there is a similar problem with BORLANDC? It should be checked!
10849 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10850 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10851 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10852 was not executed, and the compiler (cl) launched a warning:
10853 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10855 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10856 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10858 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10859 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10861 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10862 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10863 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10864 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10865 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10866 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10867 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10868 - added Release configuration in VS projects
10869 - review of compiler an linker options
10870 - VC .exe files are generated in bin_vc directory, not to interfere
10871 with binaries generated from other projects (cygwin, mingw, bcc ...)
10873 * sdcc/src/yacc.dsp: added
10875 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10876 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10877 and insert the version number definitions from .version
10879 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10881 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10882 added - genarate auto-host.h using auto-host_vc_in.h as template
10885 removed from CVS, generated automatically
10887 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10888 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10890 2002-08-11 Borut Razem <borut.razem AT siol.net>
10891 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10893 2002-08-10 Borut Razem <borut.razem AT siol.net>
10894 * src/SDCCmain.c (main):
10895 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10896 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10897 The consequence was that some temporary files were not removed.
10900 unification of code in functions tempfilename() and tempfile():
10901 function tempnam() is defined in Visual Studio 6.0 and .NET
10903 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10905 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10906 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10907 - removed compiler command line option /WX: Treats all warnings as errors
10908 - update a list of source files, included into the project
10910 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10911 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10912 changed project type to Generic Project so that can be correcly converted to VS.NET project
10914 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10916 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10918 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10920 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10921 added return 0 statements after assert() to make compiler happy
10923 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10924 added newline in the def file to keep MSC compiler satisfied
10926 * sdcc/src/z80/gen.c:
10927 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10928 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10929 - solved MSC error in function aopDump()
10931 * sdcc_vc.h: define PREFIX as "\\sdcc"
10933 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

10982 Added -p option. Allows port dependent processor to be specified.
10985 Initialized the new field char *Processor field to NULL in all ports
10988 Compiler generated registers for interrupt context saving
10989 were not getting allocated.
10991 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>

11106 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11108 * sdcc/src/SDCCloop.c:
11109 Previous fix was not good. basic blocks that have "break" or "return" are
11110 not really partof a loop , but live ranges used in these blocks should
11111 be live thru the entire loop, so set partOfLoop but don't add them to
11114 2002-02-21 <johan AT FRIJA>
11116 * src/SDCCcse.c: fixed bug #514308
11118 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
