767 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
769 Enabled VPATH feature: changed nearly all Makefiles (149 files).
770 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
772 One basic decision: e.g. src/clean.mk includes further files. In order
773 to make this work there are two solutions:
774 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
775 run configure on them. This way they can use
776 'include $(srcdir)/port-clean.mk'
777 - always include clean.mk by the Makefile at the same level. To avoid
778 that `make clean` tries to include and build Makefile.dep the
779 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
780 implemented, because now even `make uninstall` doesn't create
781 Makefile.in. clean.mk could be eliminated by pasting it in
784 * debugger/mcs51/Makefile.in: build own objects from library sources
785 (SLIB, SDCC) in current directory
787 * configure, configure.in: renamed --disable-device-lib-build in
788 --disable-device-lib; added --enable-doc, the required tools are
789 searched by configure; added result message; the toolchain for the
790 belonging ports are now only built, if the port is enabled.
792 * support/regression/*: all output is written in directory gen, because
793 the fwk and ports directories don't livet in the build tree using vpath
795 * doc/sdccman.lyx: renamed --disable-device-lib-build to
796 --disable-device-lib, added --enable-doc, added section VPATH
798 * sim/ucsim/configure.in,
799 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
800 z80 are enabled by default
802 2006-04-24 Raphael Neider <rneider AT web.de>
804 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
805 to config word, "pic14_"-prefixed some extern functions
806 (pic14_emitConfigWord): emit __config directive(s) if assignment to
807 config word has been found
808 * src/pic/device.h: added prototypes
809 * src/pic/pcode.c: added "pic14_"-prefix where needed
810 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
812 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
814 (pic14emitRegularMap): ignore config words,
815 (pic14createInterruptVect): moved generating __config directives away
816 (picglue): have __config directives emitted
818 2006-04-24 Borut Razem <borut.razem AT siol.net>

826 fixes #1469504 and #1474602,
827 (pCodeRegOptimizeRegUsage): fixed typo in comment

1073 implemented patch 1120823 Thanks to Willy De la Court (normal
1074 interrupts need an interrupt number now if they are made critical),
1075 and enabled nesting of critical functions though not for gbz80
1076 (genCritical, genEndCritical): added functions
1077 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1078 * src/z80/mappings.i: added "ei" to all mappings

1090 the left operand is shorter than the result (c* = lit-c* + int),
1092 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1095 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1097 * src/.version: increased version number to 2.5.5
1098 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1099 linking is done manually in pic16 port's _linkEdit,
1100 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1101 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1102 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1103 allocate asmop as AOP_ACC,
1104 (aopForRemat): added parameter 'bool result' in function declaration,
1105 (pic16_aopGet): return AOP_ACC when accessing WREG,
1106 (pic16_popGetTempReg): minor modification,

1117 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1118 call to allocReg, not by manually allocating a new one,
1119 (pic16_assignRegisters): now before going through the register
1120 allocating functions mark all registers as free. This eliminates some
1121 side effects resulting from peephole parser done earlier in the backbone
1123 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1181 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1182 which dumps before the function entry point a data byte which represents
1183 the number of the local variables used by the specified function, added
1184 'xinst' for initial support for Extended Instruction Support,
1185 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1186 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1187 port->fun_prefix anymore (may change later),
1188 (genFunction, genEndFunction): do not store/restore local registers for
1189 _main (this should take care the --main-return command line option in
1191 (genOr): removed some legacy pic-port instructions,
1192 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1193 performing operations with SFR's causes data to be written more than
1194 once to each SFR. Perhaps SFRs should be handled in special cases...
1195 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1197 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1198 into account for stack starting position,

1200 --extended or -y for Extended Instruction Support,
1201 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1202 (deassignLRs): *** perhaps the most important change, old 'for' code
1203 (commented out for reference), didn't account for some registers which
1204 were left marked 'not free' after a pointer operation. The change
1205 reduces register usage a lot in some cases
1207 2006-03-04 Borut Razem <borut.razem AT siol.net>

3466 2005-03-26 Raphael Neider <rneider AT web.de>
3468 * src/pic16/gen.c (genSkipc): fixed semantics (execute branch
3469 if condition == CARRY)
3470 * (genCmp): adapted to new genSkipc semantics
3471 * src/pic16/genutils.c (pic6_genCmp_special): removed side effect
3472 on rIfx (genCmp was broken)
3474 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3476 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),
3477 * src/z80/main.c (_keywords[]),
3478 * src/SDCCglobal.h (struct options),
3480 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3481 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3482 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3483 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3484 always available in leading double underscore form. The C99 support is
3485 mostly missing, but it's a start.
3486 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3487 reserved identifier "__data".
3489 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>
3491 * src/mcs51/peeph.def: fixed bug 1170013

3499 * src/SDCCcflow.c (dfNumCompare): committed the wrong version of this
3502 2005-03-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3504 * src/port.h (struct PORT),
3505 * src/avr/ralloc.c (avr_assignRegisters),
3507 * src/ds390/ralloc.c (ds390_assignRegisters),
3509 * src/hc08/ralloc.c (hc08_assignRegisters),

3531 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
3532 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
3533 immedDom() returning wrong block; probably fixes bug #1160833)
3535 2005-03-20 Borut Razem <borut.razem AT siol.net>
3537 * support/scripts/inc2h.pl: WIN32 port
3539 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
3541 * device/lib/makefile.in: added abs.c and labs.c
3543 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
3545 * device/include/stdint.h: added
3546 * device/lib/abs.c: added
3547 * device/lib/labs.c: added
3548 * device/include/stdlib.h: added abs() and labs() prototypes
3549 * device/lib/libsdcc.lib: added abs and labs
3550 * device/include/float.h,

3563 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3565 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3567 * device/lib/printf_large.c: removed inline assembly for portability and
3568 readability. Use printf_fast if speed or size are more important.
3569 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3570 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3572 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3574 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3575 prevent compiler warning
3577 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3579 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3580 moved to level 0 and declared as static. Also they are explicit
3581 placed in access bank. This was necessery because some times they
3582 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3583 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3584 optimizations. Currently only compare to unsigned char is implemented,
3585 * src/pic16/gen.c: added fReturnIdx array,
3586 * (struct resolvedIfx) is moved to gen.h and made public,
3587 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3588 * (aopForSym): added an optimization to directly store in stack of
3589 the operand of a SEND iCode,
3590 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3591 but as registers instead (AOP_REG) using the fReturnIdx array,
3592 * (pic16_freeAsmop): remove the freed register from the
3593 _G.sregsAlloc field,
3594 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3595 a compare of 'WREG',
3596 * (pic16_popGetTempRegCond): changed function prototype, now
3597 function takes also a bitVector argument v which holds the current
3598 set of registers that are allocated for stack access by aopForSym,
3599 registers allocated in aopForSym for accessing stack symbols are not
3600 any more part of the functions usedRegs field,
3601 * (genCall): some times aopOp is called for a stack variable to be
3602 send, aopForSym might perform the push, if this is true make sure
3603 that genCall doesn't push the variable twice by testing _G.resDirect,
3604 * (genFunction): changed testing for unspecified interrupt number
3605 from 256 to INTNO_UNSPEC,
3606 * modified selection scheme of frame pointer generation. Previously
3607 if function did use local registers a frame pointer was generated,
3608 now a frame pointer is generated only if function has arguments
3609 (that need PLUSW2 register access), or has stack arguments, or the
3610 compiler is not instructed to omit the frame pointer,
3611 * (genEndFunction): before restoring local registers that were saved
3612 in the function preamble, also restore the registers that *might*
3613 have been allocated for stack access,
3614 * (genRet): removed some old comments,
3615 * (genCmp, the active (RN's) version): added a call to the
3616 pic16_genCmp_special function to perform the compare with a more
3617 robust and optimized way,
3618 * (genInline): a feature has been added in inline code generation,
3619 which allows a wildcard variable substitution when writing inline
3620 assembly. Code is incomplete and experimental therefore undocumented,
3621 * (genCast): changed order of aopOp for result and right to allow
3622 aopForSym to directly load the result if possible,
3623 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3624 perform an optimized compare on some selected special occasions,
3625 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3626 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3627 generate an IVT any more,
3628 * src/pic16/main.c (pic16_optionsTable): added command line option
3630 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3631 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3633 * src/pic16/NOTES: Raphael Neider added in list of active developers
3634 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3635 jumptable_end to prevent bug #,
3636 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3637 inCond and outCond fields,
3638 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3639 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3640 turn off register spilling,
3641 * (packRegsForOneUse): synced with other ports' versions although it
3642 is not used currently,
3643 * (pic16_packRegisters): added an optimization while reading
3644 structure bitfields, some registers may be saved (malloc code is
3645 decreased by 80 bytes)
3647 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3649 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3650 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3651 this can be optimized more?
3653 2005-03-10 Raphael Neider <rneider AT web.de>
3655 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3656 genNearPointerGet): (hopefully) fixed access to bitfields via
3657 pointers (p->bitN = x; and x = p->bitN; failed)
3659 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3846 * src/pic16/main.c (_process_pragma): fixed nasty malloc bug
3847 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
3848 this might fix SIGSEGVs on MinGW...
3849 * src/SDCCopt.c (killDeadCode): restored original behaviour
3850 (volatile operands might get thrown away though)
3852 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

7375 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7377 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7378 loaded with the linker search paths (-L arguments) and the libraries
7379 to be linked with the current source (-l arguments). Changes
7380 currently will affect only the pic16 port.
7381 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7382 include path the port specific paths and port specific libraries,
7383 * gplink command now contains the $3 argument,
7384 * src/pic16/device.h,
7385 * src/pic16/device.c,: structure PIC_device is made public and
7386 renamed to PIC16_device, the same for variable Pics which is renamed

7401 Documenting changes from previous commits.
7402 * configure.in (version 1.56),
7403 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7404 when generating output files to configure the pic16 library,
7405 but now I've commented it out, since gputils aren't installed in the
7406 SF compile farm, so library won't compile
7408 * device/lib/Makefile.in (version 1.56): initially I've added in
7409 target 'all' the prerequestive 'model-pic16' so it compiled the
7410 pic16 library, but now I've commented it out for the same reasons
7412 * added targets 'model-pic16' and 'objects-pic16' to compile the
7414 * added target 'port-specific-objects-pic16' to handle the
7415 generated libraries and copy them into the build/ directory
7416 * added target 'clean-intermediate-pic16' to clean intermediate
7417 files into pic16 directory
7418 * in target 'installdirs' added line to create directory pic16 in
7419 the installation path
7421 * device/include/Makefile.in (version 1.11): in target 'install'
7422 added lines to copy all header files to installation path,
7423 * in target 'installdirs' added line create directory for pic16
7424 headers in the installation path

7439 * src/z80/main.c (_parseOptions): fixed the portmode= command line
7440 option so that it actually works. Made it specific to the z80, since
7441 the gbz80 doesn't have these kinds of I/O ports.
7443 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7469 via literal number. The symbol is placed in the corresponding
7470 position of the data ram
7471 * (pic16_dump_section): relocatable and absolute uninitialized
7472 data are now emitted in sorted order to reduce section naming,
7473 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
7474 weren't marked as being in the access bank,
7476 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
7478 Added portion of GNU PIC Library under the directory
7479 device/include/pic16 and device/lib/pic16. These files

7511 all over. Telling LaTeX to be less strict with word spacing
7512 to better keep the right margin. Changed some notes about
7513 maintainance of the ports in section 3.2.1 - is it OK like this?
7515 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

7555 * src/pic16/peeph.def: all peepholes with movff are commented out,
7556 because there is a problem in the pcode peep optimizer,
7557 * src/pic16/ralloc.c: the register allocator can now reuse local

7634 2004-01-07 Borut Razem <borut.razem AT siol.net>
7636 * support/scripts/sdcc.nsi: update PATH
7637 * support/scripts/sdcc.ico: craeted

7650 include information about variables allocated to the overlay
7653 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7655 * as/mcs51/lkmain.c: Help about -Y option

7667 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7669 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7670 (default behaviour).
7672 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7674 A python script to validate compiler diagnostic messages. It can be
7675 used to verify that sdcc complains about bad c source code and
7676 gives a good location of the error.
7677 * support/valdiag/Makefile,
7678 * support/valdiag/valdiag.py,
7679 * support/valdiag/tests/*
7681 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7695 around the header file.
7696 Bug reported from Jesus Calvino-Fraga
7698 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7700 * sdcc.spec: updated
7701 * device/include/Makefile.in: don't install CVS directories
7702 * device/lib/Makefile.in: added removal of CVS directories after install
7703 * doc/Makefile: fixed install, added local_icons
7704 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7705 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7706 * src/ds390/gen.c (genRightShift): fixed bug #870788
7707 * src/SDCCast.c (decorateType): fixed bug #870781
7709 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7711 PIC16 port related changes:
7712 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7713 added variable stackPos,
7715 * gen.c: genCall, assignResultValue: added support for
7716 pushing/retrieving function parameters to/from stack,
7717 genFunction,genEndFunction: setup stack frame for the
7719 genAddrOf: will be changed according to bug 863624
7721 * added files genutils.c and genutils.h which contain gen*
7722 debugged and optimised functions extracted from gen.c
7724 * glue.c: added variable 'externs' which holds extern symbols,
7725 pic16emitRegularMap: is modified to properly handle relocatable
7726 symbols under the new scheme,
7727 pic16createInterruptVect: is modified
7728 pic16printPublics: is modified to emit 'global' assembler directives,
7729 added pic16_printExterns to print extern symbols,
7730 pic16glue: initializes stack/frame pointer in the beginning of
7731 the assembly output. Temporary hack, will be corrected later,
7732 because gplink yet does not support stack and SDCC does not
7733 yet support a type of crt0.o object to create the final binary.
7735 * Removed many lines that contain 8051 legacy code.
7736 * The code is finally placed under a 'code' directive.
7737 * Added port specific options.
7739 * _process_pragma: simplified since now we do not need *special*
7740 include file to define SFR registers. But a separate header
7741 will be needed. This will be developed later.
7742 * _pic16_parseOptions: added, parses port specific options:
7743 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7744 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7745 --preplace-udata-with=
7747 * _pic16_setDefaultOptions: modified to initialize section names,
7748 but hack is temporarly out of order since it needs improvement.
7749 * _pic16_genAssemblerPreamble: configuration words are emitted by
7750 their address instead of their name. This part is incomplete and
7751 supports only the 18Fxx2 devices. Other devices will emit an error
7752 during assembly since they do not contain the same set of config
7754 * _pic16_genIVT: is modified,
7756 * pcode.c: added definitions for some hardware registers that are needed
7758 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7759 All PCI entries are updated. Now LFSR is supported.
7760 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7761 * added pic16_newpCodeOpLit2 to support instructions with
7762 two literal arguments
7763 * pic16_pCode2str: corrected code that emits assembler instructions
7764 with two literal operands and those that have an access bit modifier
7765 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7766 this fixes a bug which caused some labels to be lost, when an
7767 assembler directive was added, i.e. banksel,
7768 * pic16_FixRegisterBanking: improved logic that causes the insertion
7770 * InlineFunction: functions that are called once, are not any more
7771 inlined. This can be a port option in the future,
7773 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7775 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7776 hold the corresponding uninitialized symbols,
7777 * pic16_allocProcessorRegister: registers have explicit marked the
7779 * pic16_allocInternalRegister: registers are explicit marked as
7781 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7782 processing list, so bit registers were lost,
7785 * ralloc.h: added field 'accessBank' and original symbol operand
7786 in register definition,
7787 * removed the field isMapped from register definition,
7789 ** Several functions have been removed from various sources:
7790 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7791 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7792 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7793 pic16_assignRelocatableRegisters
7795 ** others have been introduced:
7796 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7797 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7799 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7801 * support/scripts/inc2h.pl: changed definition of BIT_AT
7802 to emit 'sbit at' instead of 'bit at'. This was a request.
7804 PIC16 port related preliminary changes:
7805 * gen.c: prefixed function popRegFromString with
7806 pic16_ and all references to it corrected
7807 * pcode.c: all pic16_pc_* hardware registers prefixed
7808 with underscore (_),
7809 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7810 * ralloc.c: newReg(): when register is REG_SFR then
7811 set address to rIdx,
7812 pic16_allocProcessorRegister(): marks register wasUsed=0
7813 pic16_writeUsedRegs(): added a call to assign processor
7814 registers via pic16_assignFixedRegisters
7816 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7818 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7819 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7820 variables in unused register banks. Also the SSEG is placed
7821 wherever there is enough space for it, and IDATA can be anywhere
7822 in internal RAM. For now compile using -Wl-Y[stack_size].
7823 The mem file is different for this option as well, since it
7824 makes no sense of talking about DSEG lenght.
7826 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7828 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7829 in certain cases, e.g. when ROM assignment, patch provided
7830 from Albert den Haan.
7832 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8855 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8856 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8857 type for bits was changed. It resulted in bit variables becoming

8875 A few small changes that speed up the peephole optimizer.
8879 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8881 Try to make the peephole optimizer smarter by maintaining
8882 an association between the assembly source code and the
8883 iCodes that originated them. Put this information to use
8884 with a new peephole rule condition "notVolatile" so that
8885 the rules can be aggressive yet still safe.
8890 * src/mcs51/peeph.def
8892 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8896 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8897 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8898 if the left or right operand symbols have the accuse flag set.
8900 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8902 Changed the type of the result of the ! (NOT) operator to char;
8903 previously it returned the same type as the source. This allows
8904 us to eliminate all the genFloatNot functions (all of its target
8905 implementations were very buggy) since !float can use the same

8917 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8918 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8919 during interrupts. Ensure WSAVE is located at a shared bank address.
8920 2. Fixed page selection in some places
8921 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8922 the registers name strings.
8923 4. Fixed "signed / unsigned compare" compiler warnings.
8924 5. The PIC port manages its own allocation of the general purpose
8925 registers, but makes no attempt to reuse them. As a result when
8926 compiling it soon runs out of general purpose registers. Some
8927 additional code was added to the files pcode.c and device.c to walk
8928 through the function call tree and rename the registers so that they
8938 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8939 genPlus() & genMinus() when the result is the same as left or right

8945 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8947 Made bitfield a distinct type from bit so that bitfields
8948 convert as per ANSI C and bits retain their traditional
8949 boolean style behaviour. Implemented bitfield support in

8965 access to xdata mapped I/O devices.
8967 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8969 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8971 Cleaned up genPackBits and genUnpackBits and added two helper
8972 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8973 for literal assignments in genPackBits (thanks to Frieder for
8979 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8981 Fixed bug #748310 (pointer to function type mishandled when the
8982 function name is omitted). Also fixed a SIGSEGV when a function
8983 attribute (reentrant, etc) is used on a non-function or on a
8984 function but misplaced before the parameter list.

9013 Made the constant following the "interrupt" keyword optional. If
9014 omitted, the function will not automatically be given an entry
9015 in the interrupt vector table (similar to #pragma NOIV, but
9016 less syntacticly kludgy). The interrupt number is also now
9017 range checked. Also fixed a bug in the high order bit example

9038 unsigned, but are signed by default
9039 * src/SDCCval.c (constVal): rearranged
9040 * src/SDCCval.c (valMod): preliminary fix
9041 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9532 * doc/sdccman.lyx: fixed bug 739745
9533 * src/pic16/pcode.c (pic16_get_op): fixed warning on alpha
9535 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
9537 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
9538 it can be defined with CFLAGS when running configure
9539 * src/SDCCmain.c: fixed compiling + linking with object files
9541 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
9543 * configure.in: configure for pic16 port,
9544 added --disable-pic16-port
9545 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
9546 * src/SDCCmain.c: linkOptions is changed to set *,
9547 added if/endif conditional macros to remove options help
9548 messages from optionsTable when a port is not configured, added
9549 support for the PIc16 port in the ports table, when executing
9550 the compiler with no port specified on command line, a default
9551 port is selected with the new macro DEFAULT_PORT which is
9552 defined in port.h, in setDefaultOptions() linkOptions is removed
9553 from initialization assignment, since now it is a set,
9554 parseCmdLine uses setParseWithComma for linkOptions, in
9555 linkEdit() linkOptions are accessed with new function indexSet()
9556 which returns the i'th item of a set variable. See SDCCset.c, in
9557 linkEdit() when calling buildCmdLine(), added linkOptions as
9558 last argument. Now users can pass arguments to gplink via the
9559 -Wl option, main() uses pic16glue() to glue up pic16 programs
9560 * src/SDCCpeeph.c: various changes to support pic16
9561 * src/SDCCset.c: added function void *indexSet(set *, int) to

9571 * src/pic16/glue.c: commented out some error producing lines
9572 * src/pic16/main.c: __config directives are commented out to stop
9573 gpasm complaining and test the linkage with gplink, _linkCmd and
9574 _asmCmd changed to be more gplink and gpasm friendly
9575 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9576 produced an error when parsed, peep rule 12 is added to utilize
9577 movff, but it is commented out since the pCode does not support
9578 yet a command with 2 address arguments
9580 2003-05-18 <johan AT balder>
9582 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9609 2003-05-11 Borut Razem <borut.razem AT siol.net>
9611 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9612 the path of bin directory, so that PATH is the only env. variable, which has to be set
9613 in case of standard installation.

10641 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10643 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10645 * in \sdcc\as\mcs51\ changed these files in order to create an
10646 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10647 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10648 following files to include the previous two files: aslink.dsp,
10649 Makefile.aslink, Makefile.bcc, and Makefile.in.
10651 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10652 .adb instead of .cdb
10654 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10656 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10657 value from option --iram-size.
10659 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10661 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10664 2002-09-18 <wiml AT hhhh.org>
10666 * SDCClrange.h: exposed setFromRange() and setToRange()
10667 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10668 packRegsForAccUse() (bug 542397)
10669 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10670 multiple times and emitting the fetch operations more than once
10671 added aopGetUsesAcc() function to allow binary operators to
10672 fetch their operands in the correct order; made genMinus() emit
10673 compact code for X = LITERAL - Y
10675 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10676 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10677 sprintf() in line 1267.
10679 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10680 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10683 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10684 Changes to aslink (All the changes are marked with 'JCF'):
10686 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10689 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10690 area BSEG. Also moves, if possible, the DATA area down into the internal
10691 ram so more space is available.
10693 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10696 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10697 not bytes. Function summary() which creates a memory usage summary
10698 file with extension .mem. Reports of overlaping stack and small stack
10699 size. If the space for the stack is less than 16 bytes aslink trows a
10702 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10703 the 8051. Option 'y' for memory summary output file.
10705 Changes to sdcc (All the changes are marked with 'JCF'):
10707 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10709 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10710 overlaying area for it (uses RegBankUsed[4]).
10712 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10713 bank zero as used by default. By default aslink locates the stack
10714 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10715 the creation of the .mem file. Delegates the allocation of data area
10716 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10717 the begining of the stack area to aslink.
10719 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10720 glue() in SDCCglue.c creates an area for it.
10722 2002-09-03 Borut Razem <borut.razem AT siol.net>
10723 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10724 sdcc/src/pic/glue.c:
10725 introduced atexit() handler for teporay files removal in case of
10726 errors, assertions, ...
10728 2002-08-29 Borut Razem <borut.razem AT siol.net>
10729 * sdcc/support/cpp2/auto-host_vc_in.h:
10730 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10731 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10732 Maybe there is a similar problem with BORLANDC? It should be checked!
10734 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10735 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10736 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10737 was not executed, and the compiler (cl) launched a warning:
10738 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10740 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10741 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10743 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10744 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10746 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10747 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,

10751 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10752 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10753 - added Release configuration in VS projects
10754 - review of compiler an linker options
10755 - VC .exe files are generated in bin_vc directory, not to interfere
10756 with binaries generated from other projects (cygwin, mingw, bcc ...)
10758 * sdcc/src/yacc.dsp: added
10760 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10761 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10762 and insert the version number definitions from .version
10764 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10766 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10767 added - genarate auto-host.h using auto-host_vc_in.h as template
10770 removed from CVS, generated automatically
10772 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10773 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10775 2002-08-11 Borut Razem <borut.razem AT siol.net>
10776 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10778 2002-08-10 Borut Razem <borut.razem AT siol.net>
10779 * src/SDCCmain.c (main):
10780 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10781 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10782 The consequence was that some temporary files were not removed.
10785 unification of code in functions tempfilename() and tempfile():
10786 function tempnam() is defined in Visual Studio 6.0 and .NET
10788 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10790 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10791 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10792 - removed compiler command line option /WX: Treats all warnings as errors
10793 - update a list of source files, included into the project
10795 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10796 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10797 changed project type to Generic Project so that can be correcly converted to VS.NET project
10799 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10801 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()

10994 Previous fix was not good. basic blocks that have "break" or "return" are
10995 not really partof a loop , but live ranges used in these blocks should
