631 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
633 Enabled VPATH feature: changed nearly all Makefiles (149 files).
634 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
636 One basic decision: e.g. src/clean.mk includes further files. In order
637 to make this work there are two solutions:
638 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
639 run configure on them. This way they can use
640 'include $(srcdir)/port-clean.mk'
641 - always include clean.mk by the Makefile at the same level. To avoid
642 that `make clean` tries to include and build Makefile.dep the
643 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
644 implemented, because now even `make uninstall` doesn't create
645 Makefile.in. clean.mk could be eliminated by pasting it in
648 * debugger/mcs51/Makefile.in: build own objects from library sources
649 (SLIB, SDCC) in current directory
651 * configure, configure.in: renamed --disable-device-lib-build in
652 --disable-device-lib; added --enable-doc, the required tools are
653 searched by configure; added result message; the toolchain for the
654 belonging ports are now only built, if the port is enabled.
656 * support/regression/*: all output is written in directory gen, because
657 the fwk and ports directories don't livet in the build tree using vpath
659 * doc/sdccman.lyx: renamed --disable-device-lib-build to
660 --disable-device-lib, added --enable-doc, added section VPATH
662 * sim/ucsim/configure.in,
663 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
664 z80 are enabled by default
666 2006-04-24 Raphael Neider <rneider AT web.de>
668 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
669 to config word, "pic14_"-prefixed some extern functions
670 (pic14_emitConfigWord): emit __config directive(s) if assignment to
671 config word has been found
672 * src/pic/device.h: added prototypes
673 * src/pic/pcode.c: added "pic14_"-prefix where needed

676 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

679 (pic14createInterruptVect): moved generating __config directives away

951 2006-03-16 Raphael Neider <rneider AT web.de>
953 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
954 the left operand is shorter than the result (c* = lit-c* + int),
956 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
959 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
961 * src/.version: increased version number to 2.5.5
962 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
963 linking is done manually in pic16 port's _linkEdit,
964 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
965 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
966 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
967 allocate asmop as AOP_ACC,
968 (aopForRemat): added parameter 'bool result' in function declaration,
969 (pic16_aopGet): return AOP_ACC when accessing WREG,
970 (pic16_popGetTempReg): minor modification,
971 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
972 'pic16_allocWithIdx',
973 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
974 calling function in absolute addresses,
975 (genAssign): take into account AOP_ACC asmop,
976 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
977 * src/pic16/pcoderegs.c: some debug functions and lines added,
978 * src/pic16/ralloc.c (decodeRegType): added but commented out,
979 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
981 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
982 call to allocReg, not by manually allocating a new one,
983 (pic16_assignRegisters): now before going through the register
984 allocating functions mark all registers as free. This eliminates some
985 side effects resulting from peephole parser done earlier in the backbone
987 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
989 * src/SDCCicode.c (geniCodeLogic),

1008 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1009 (aopForSym, aopOp): increment asmop.allocated if reused,
1010 (freeAsmop): decrement asmop.allocated and check for zero instead of
1012 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1013 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

1037 2006-03-06 Borut Razem <borut.razem AT siol.net>
1039 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1040 made the linker quiet
1042 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1044 * src/pic16/gen.c (genPcall): fixed bug #1443644
1045 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1046 which dumps before the function entry point a data byte which represents
1047 the number of the local variables used by the specified function, added
1048 'xinst' for initial support for Extended Instruction Support,
1049 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1050 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1051 port->fun_prefix anymore (may change later),
1052 (genFunction, genEndFunction): do not store/restore local registers for
1053 _main (this should take care the --main-return command line option in
1055 (genOr): removed some legacy pic-port instructions,
1056 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1057 performing operations with SFR's causes data to be written more than
1058 once to each SFR. Perhaps SFRs should be handled in special cases...
1059 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1061 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1062 into account for stack starting position,
1063 (struct OPTIONS pic16_optionsTable): added command line argument
1064 --extended or -y for Extended Instruction Support,
1065 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1066 (deassignLRs): *** perhaps the most important change, old 'for' code
1067 (commented out for reference), didn't account for some registers which
1068 were left marked 'not free' after a pointer operation. The change
1069 reduces register usage a lot in some cases

3427 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3429 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3431 * device/lib/printf_large.c: removed inline assembly for portability and
3432 readability. Use printf_fast if speed or size are more important.
3433 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3434 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3436 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3438 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3439 prevent compiler warning
3441 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3443 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3444 moved to level 0 and declared as static. Also they are explicit
3445 placed in access bank. This was necessery because some times they
3446 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3447 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3448 optimizations. Currently only compare to unsigned char is implemented,
3449 * src/pic16/gen.c: added fReturnIdx array,
3450 * (struct resolvedIfx) is moved to gen.h and made public,
3451 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3452 * (aopForSym): added an optimization to directly store in stack of
3453 the operand of a SEND iCode,
3454 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3455 but as registers instead (AOP_REG) using the fReturnIdx array,
3456 * (pic16_freeAsmop): remove the freed register from the
3457 _G.sregsAlloc field,
3458 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3459 a compare of 'WREG',
3460 * (pic16_popGetTempRegCond): changed function prototype, now
3461 function takes also a bitVector argument v which holds the current
3462 set of registers that are allocated for stack access by aopForSym,
3463 registers allocated in aopForSym for accessing stack symbols are not
3464 any more part of the functions usedRegs field,
3465 * (genCall): some times aopOp is called for a stack variable to be
3466 send, aopForSym might perform the push, if this is true make sure
3467 that genCall doesn't push the variable twice by testing _G.resDirect,
3468 * (genFunction): changed testing for unspecified interrupt number
3469 from 256 to INTNO_UNSPEC,
3470 * modified selection scheme of frame pointer generation. Previously
3471 if function did use local registers a frame pointer was generated,
3472 now a frame pointer is generated only if function has arguments
3473 (that need PLUSW2 register access), or has stack arguments, or the
3474 compiler is not instructed to omit the frame pointer,
3475 * (genEndFunction): before restoring local registers that were saved
3476 in the function preamble, also restore the registers that *might*
3477 have been allocated for stack access,
3478 * (genRet): removed some old comments,
3479 * (genCmp, the active (RN's) version): added a call to the
3480 pic16_genCmp_special function to perform the compare with a more
3481 robust and optimized way,
3482 * (genInline): a feature has been added in inline code generation,
3483 which allows a wildcard variable substitution when writing inline
3484 assembly. Code is incomplete and experimental therefore undocumented,

4155 Adding support for replacing ljmps with sjmps in jumptables
4156 generated for switch statements. For now you need to set the
4157 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4158 Now 4 algorithms for mcs51 jumptable generation are used:
4159 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4160 addresses loaded pc-relative for up to 112 cases and stack-pushing
4161 target addresses loaded with offset from dptr for up to 256 cases.

4191 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4193 * added libc directory. The current version of LibC contains string
4194 functions, ctype functions and macros and some functions of the
4195 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4196 be extensively tested in the future. Standard disclaimer here.
4197 Library is not automatically build yet. But one can build it by
4198 invoking 'make' inside the libc directory.

4209 * (pic16_storeForReturn): optimized return of 0,
4210 * (genCmp): experimental code for new genCmp which uses PIC18's
4211 special compare&skip instructions. Initial tests fail some times
4212 with variables grater than 1 byte in size, so new code is disabled,
4213 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4215 * (genCast): began a fix to optimize the casting of a bit to another
4216 bit, now assigning a bitfield to another bitfield will fail, sorry,
4217 * src/pic16/main.c: disabled the use of lr-support feature,
4218 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4224 * (isBankInstruction): modified to return 0 for no banking instruction,
4225 and 1 for banking instruction,
4226 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4227 caused stop processing pCodes after a inline assembly block,
4228 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4229 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4230 registers when it shouldn't,
4231 * src/pic16/ralloc.c (allocReg): add preliminary support for
4232 supporting a limited set of temporary registers,
4234 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4240 (genFunction): optimize RECEIVE iCodes in reentrant functions
4242 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7242 loaded with the linker search paths (-L arguments) and the libraries
7243 to be linked with the current source (-l arguments). Changes
7244 currently will affect only the pic16 port.
7245 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7246 include path the port specific paths and port specific libraries,
7247 * gplink command now contains the $3 argument,
7248 * src/pic16/device.h,
7249 * src/pic16/device.c,: structure PIC_device is made public and

7265 Documenting changes from previous commits.
7266 * configure.in (version 1.56),
7267 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7268 when generating output files to configure the pic16 library,
7269 but now I've commented it out, since gputils aren't installed in the
7270 SF compile farm, so library won't compile
7272 * device/lib/Makefile.in (version 1.56): initially I've added in
7273 target 'all' the prerequestive 'model-pic16' so it compiled the
7274 pic16 library, but now I've commented it out for the same reasons
7276 * added targets 'model-pic16' and 'objects-pic16' to compile the
7278 * added target 'port-specific-objects-pic16' to handle the
7279 generated libraries and copy them into the build/ directory
7280 * added target 'clean-intermediate-pic16' to clean intermediate
7281 files into pic16 directory
7282 * in target 'installdirs' added line to create directory pic16 in

7527 * src/SDCCast.c (decorateType),
7528 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7529 LEFT_OP (left shift)
7531 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7533 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7534 (default behaviour).
7536 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7538 A python script to validate compiler diagnostic messages. It can be
7539 used to verify that sdcc complains about bad c source code and
7540 gives a good location of the error.
7541 * support/valdiag/Makefile,
7542 * support/valdiag/valdiag.py,
7543 * support/valdiag/tests/*

7560 Bug reported from Jesus Calvino-Fraga
7562 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7564 * sdcc.spec: updated
7565 * device/include/Makefile.in: don't install CVS directories
7566 * device/lib/Makefile.in: added removal of CVS directories after install
7567 * doc/Makefile: fixed install, added local_icons
7568 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7569 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7570 * src/ds390/gen.c (genRightShift): fixed bug #870788

7573 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7575 PIC16 port related changes:
7576 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7577 added variable stackPos,
7579 * gen.c: genCall, assignResultValue: added support for
7580 pushing/retrieving function parameters to/from stack,
7581 genFunction,genEndFunction: setup stack frame for the
7583 genAddrOf: will be changed according to bug 863624
7585 * added files genutils.c and genutils.h which contain gen*
7586 debugged and optimised functions extracted from gen.c
7588 * glue.c: added variable 'externs' which holds extern symbols,
7589 pic16emitRegularMap: is modified to properly handle relocatable
7590 symbols under the new scheme,
7591 pic16createInterruptVect: is modified
7592 pic16printPublics: is modified to emit 'global' assembler directives,
7593 added pic16_printExterns to print extern symbols,
7594 pic16glue: initializes stack/frame pointer in the beginning of
7595 the assembly output. Temporary hack, will be corrected later,
7596 because gplink yet does not support stack and SDCC does not
7597 yet support a type of crt0.o object to create the final binary.
7599 * Removed many lines that contain 8051 legacy code.
7600 * The code is finally placed under a 'code' directive.
7601 * Added port specific options.
7603 * _process_pragma: simplified since now we do not need *special*
7604 include file to define SFR registers. But a separate header
7605 will be needed. This will be developed later.
7606 * _pic16_parseOptions: added, parses port specific options:
7607 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7608 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7609 --preplace-udata-with=
7611 * _pic16_setDefaultOptions: modified to initialize section names,
7612 but hack is temporarly out of order since it needs improvement.
7613 * _pic16_genAssemblerPreamble: configuration words are emitted by
7614 their address instead of their name. This part is incomplete and
7615 supports only the 18Fxx2 devices. Other devices will emit an error
7616 during assembly since they do not contain the same set of config
7618 * _pic16_genIVT: is modified,
7620 * pcode.c: added definitions for some hardware registers that are needed
7622 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7623 All PCI entries are updated. Now LFSR is supported.
7624 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7625 * added pic16_newpCodeOpLit2 to support instructions with
7626 two literal arguments
7627 * pic16_pCode2str: corrected code that emits assembler instructions
7628 with two literal operands and those that have an access bit modifier
7629 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7630 this fixes a bug which caused some labels to be lost, when an
7631 assembler directive was added, i.e. banksel,
7632 * pic16_FixRegisterBanking: improved logic that causes the insertion
7634 * InlineFunction: functions that are called once, are not any more
7635 inlined. This can be a port option in the future,
7637 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7639 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7640 hold the corresponding uninitialized symbols,
7641 * pic16_allocProcessorRegister: registers have explicit marked the
7643 * pic16_allocInternalRegister: registers are explicit marked as
7645 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7646 processing list, so bit registers were lost,
7649 * ralloc.h: added field 'accessBank' and original symbol operand
7650 in register definition,
7651 * removed the field isMapped from register definition,
7653 ** Several functions have been removed from various sources:
7654 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7655 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7656 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7657 pic16_assignRelocatableRegisters
7659 ** others have been introduced:
7660 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7661 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7663 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7665 * support/scripts/inc2h.pl: changed definition of BIT_AT
7666 to emit 'sbit at' instead of 'bit at'. This was a request.
7668 PIC16 port related preliminary changes:
7669 * gen.c: prefixed function popRegFromString with
7670 pic16_ and all references to it corrected
7671 * pcode.c: all pic16_pc_* hardware registers prefixed
7672 with underscore (_),
7673 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7674 * ralloc.c: newReg(): when register is REG_SFR then
7675 set address to rIdx,
7676 pic16_allocProcessorRegister(): marks register wasUsed=0
7677 pic16_writeUsedRegs(): added a call to assign processor
7678 registers via pic16_assignFixedRegisters
7680 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7682 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7683 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7684 variables in unused register banks. Also the SSEG is placed
7685 wherever there is enough space for it, and IDATA can be anywhere
7686 in internal RAM. For now compile using -Wl-Y[stack_size].
7687 The mem file is different for this option as well, since it
7688 makes no sense of talking about DSEG lenght.
7690 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7692 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7693 in certain cases, e.g. when ROM assignment, patch provided
7694 from Albert den Haan.
7696 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7935 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7937 * src/SDCCast.c (decorateType): disabled a transformation I added in
7938 revision 1.188 (access to fields of a structure at an absolute address);
7939 it breaks with bitfields, extern declarations, and gcse analysis.
7940 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7941 could be assigned through a pointer, so don't complain.
7942 * src/SDCCast.c (astErrors),
7944 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
7946 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

8698 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8699 fetching of the pointer
8700 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8701 copied from genNearPointerSet()
8702 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8703 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8719 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8720 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8721 type for bits was changed. It resulted in bit variables becoming
8722 global, which is not permitted in PIC 14 assembly output.
8724 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

8739 A few small changes that speed up the peephole optimizer.
8743 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8745 Try to make the peephole optimizer smarter by maintaining
8746 an association between the assembly source code and the
8747 iCodes that originated them. Put this information to use
8748 with a new peephole rule condition "notVolatile" so that
8749 the rules can be aggressive yet still safe.
8754 * src/mcs51/peeph.def
8756 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8760 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8761 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8762 if the left or right operand symbols have the accuse flag set.
8764 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8766 Changed the type of the result of the ! (NOT) operator to char;
8767 previously it returned the same type as the source. This allows
8768 us to eliminate all the genFloatNot functions (all of its target
8769 implementations were very buggy) since !float can use the same
8772 * src/SDCCicode.c (ast2iCode): ! returns char

8781 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8782 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8783 during interrupts. Ensure WSAVE is located at a shared bank address.
8784 2. Fixed page selection in some places
8785 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8786 the registers name strings.
8787 4. Fixed "signed / unsigned compare" compiler warnings.
8788 5. The PIC port manages its own allocation of the general purpose
8789 registers, but makes no attempt to reuse them. As a result when
8790 compiling it soon runs out of general purpose registers. Some
8791 additional code was added to the files pcode.c and device.c to walk
8792 through the function call tree and rename the registers so that they
8802 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8803 genPlus() & genMinus() when the result is the same as left or right

8809 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8811 Made bitfield a distinct type from bit so that bitfields
8812 convert as per ANSI C and bits retain their traditional
8813 boolean style behaviour. Implemented bitfield support in
8821 * src/ds390/gen.c: bit v bitfield split
8822 * src/z80/gen.c: New support for bitfields
8823 * support/regression/tests/bitfields.c: reenabled z80,
8826 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8828 Rules 246.x, 247.x relate to bitfields, the others speed up
8829 access to xdata mapped I/O devices.
8831 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8833 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8835 Cleaned up genPackBits and genUnpackBits and added two helper
8836 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8837 for literal assignments in genPackBits (thanks to Frieder for
8843 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8845 Fixed bug #748310 (pointer to function type mishandled when the
8846 function name is omitted). Also fixed a SIGSEGV when a function
8847 attribute (reentrant, etc) is used on a non-function or on a
8848 function but misplaced before the parameter list.
8850 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8852 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8853 * support/Util/SDCCerr.h,

8875 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8877 Made the constant following the "interrupt" keyword optional. If
8878 omitted, the function will not automatically be given an entry
8879 in the interrupt vector table (similar to #pragma NOIV, but
8880 less syntacticly kludgy). The interrupt number is also now
8881 range checked. Also fixed a bug in the high order bit example

9413 support for the PIc16 port in the ports table, when executing
9414 the compiler with no port specified on command line, a default
9415 port is selected with the new macro DEFAULT_PORT which is
9416 defined in port.h, in setDefaultOptions() linkOptions is removed
9417 from initialization assignment, since now it is a set,
9418 parseCmdLine uses setParseWithComma for linkOptions, in
9419 linkEdit() linkOptions are accessed with new function indexSet()
9420 which returns the i'th item of a set variable. See SDCCset.c, in
9421 linkEdit() when calling buildCmdLine(), added linkOptions as
9422 last argument. Now users can pass arguments to gplink via the
9423 -Wl option, main() uses pic16glue() to glue up pic16 programs

9437 gpasm complaining and test the linkage with gplink, _linkCmd and
9438 _asmCmd changed to be more gplink and gpasm friendly
9439 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9440 produced an error when parsed, peep rule 12 is added to utilize
9441 movff, but it is commented out since the pCode does not support
9442 yet a command with 2 address arguments
9444 2003-05-18 <johan AT balder>

10505 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10507 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10509 * in \sdcc\as\mcs51\ changed these files in order to create an
10510 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10511 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10512 following files to include the previous two files: aslink.dsp,
10513 Makefile.aslink, Makefile.bcc, and Makefile.in.
10515 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10516 .adb instead of .cdb
10518 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10520 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10521 value from option --iram-size.
10523 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10525 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10528 2002-09-18 <wiml AT hhhh.org>
10530 * SDCClrange.h: exposed setFromRange() and setToRange()
10531 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10532 packRegsForAccUse() (bug 542397)
10533 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10534 multiple times and emitting the fetch operations more than once
10535 added aopGetUsesAcc() function to allow binary operators to
10536 fetch their operands in the correct order; made genMinus() emit
10537 compact code for X = LITERAL - Y
10539 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10540 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10541 sprintf() in line 1267.
10543 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10544 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10547 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10548 Changes to aslink (All the changes are marked with 'JCF'):
10550 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10553 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10554 area BSEG. Also moves, if possible, the DATA area down into the internal
10555 ram so more space is available.
10557 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10560 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10561 not bytes. Function summary() which creates a memory usage summary
10562 file with extension .mem. Reports of overlaping stack and small stack
10563 size. If the space for the stack is less than 16 bytes aslink trows a
10566 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10567 the 8051. Option 'y' for memory summary output file.
10569 Changes to sdcc (All the changes are marked with 'JCF'):
10571 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10573 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10574 overlaying area for it (uses RegBankUsed[4]).
10576 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10577 bank zero as used by default. By default aslink locates the stack
10578 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10579 the creation of the .mem file. Delegates the allocation of data area
10580 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10581 the begining of the stack area to aslink.
10583 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10584 glue() in SDCCglue.c creates an area for it.
10586 2002-09-03 Borut Razem <borut.razem AT siol.net>
10587 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10588 sdcc/src/pic/glue.c:
10589 introduced atexit() handler for teporay files removal in case of
10590 errors, assertions, ...
10592 2002-08-29 Borut Razem <borut.razem AT siol.net>
10593 * sdcc/support/cpp2/auto-host_vc_in.h:
10594 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10595 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10596 Maybe there is a similar problem with BORLANDC? It should be checked!
10598 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10599 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10600 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10601 was not executed, and the compiler (cl) launched a warning:
10602 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10604 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10605 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10607 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10608 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10610 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10611 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10612 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10613 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10614 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10615 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10616 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10617 - added Release configuration in VS projects
10618 - review of compiler an linker options
10619 - VC .exe files are generated in bin_vc directory, not to interfere
10620 with binaries generated from other projects (cygwin, mingw, bcc ...)
10622 * sdcc/src/yacc.dsp: added
10624 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10625 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10626 and insert the version number definitions from .version
10628 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10630 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10631 added - genarate auto-host.h using auto-host_vc_in.h as template
10634 removed from CVS, generated automatically
10636 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10637 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10639 2002-08-11 Borut Razem <borut.razem AT siol.net>
10640 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10642 2002-08-10 Borut Razem <borut.razem AT siol.net>
10643 * src/SDCCmain.c (main):
10644 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10645 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10646 The consequence was that some temporary files were not removed.
10649 unification of code in functions tempfilename() and tempfile():
10650 function tempnam() is defined in Visual Studio 6.0 and .NET
10652 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10654 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10655 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10656 - removed compiler command line option /WX: Treats all warnings as errors
10657 - update a list of source files, included into the project
10659 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10660 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10661 changed project type to Generic Project so that can be correcly converted to VS.NET project
10663 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10665 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10667 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10669 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10670 added return 0 statements after assert() to make compiler happy
10672 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10673 added newline in the def file to keep MSC compiler satisfied
10675 * sdcc/src/z80/gen.c:
10676 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10677 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10678 - solved MSC error in function aopDump()
10680 * sdcc_vc.h: define PREFIX as "\\sdcc"
10682 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10683 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10686 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10687 - Rewrote the register banking algorithm.
10688 - Added pCode live-range analysis to registers (for now, only non-used and
10689 singly-used registers optimized away)
10691 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10693 * 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.

10722 2002-03-28 Johan Knol <johan AT balder>
10724 * src/SDCCval.c: fixed bug #532436
10726 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10728 Added "char *Processor" field to the port structure.
10731 Added -p option. Allows port dependent processor to be specified.
10734 Initialized the new field char *Processor field to NULL in all ports
10737 Compiler generated registers for interrupt context saving
10738 were not getting allocated.
10740 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10743 Fixed left shift. Will promote the left side of a left shift
10744 if a) left shifting more than size of operand or b) when assigned
10745 to something size > size of left side
10747 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10749 tons of changes. Register allocation has been
10750 rewritten. Added customization for the various PICs. Flow
10751 analysis is restructured. ...

10858 Previous fix was not good. basic blocks that have "break" or "return" are
10859 not really partof a loop , but live ranges used in these blocks should
10860 be live thru the entire loop, so set partOfLoop but don't add them to
