626 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
628 Enabled VPATH feature: changed nearly all Makefiles (149 files).
629 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
631 One basic decision: e.g. src/clean.mk includes further files. In order
632 to make this work there are two solutions:
633 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
634 run configure on them. This way they can use
635 'include $(srcdir)/port-clean.mk'
636 - always include clean.mk by the Makefile at the same level. To avoid
637 that `make clean` tries to include and build Makefile.dep the
638 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
639 implemented, because now even `make uninstall` doesn't create
640 Makefile.in. clean.mk could be eliminated by pasting it in
643 * debugger/mcs51/Makefile.in: build own objects from library sources
644 (SLIB, SDCC) in current directory
646 * configure, configure.in: renamed --disable-device-lib-build in
647 --disable-device-lib; added --enable-doc, the required tools are
648 searched by configure; added result message; the toolchain for the
649 belonging ports are now only built, if the port is enabled.
651 * support/regression/*: all output is written in directory gen, because
652 the fwk and ports directories don't livet in the build tree using vpath
654 * doc/sdccman.lyx: renamed --disable-device-lib-build to
655 --disable-device-lib, added --enable-doc, added section VPATH
657 * sim/ucsim/configure.in,
658 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
659 z80 are enabled by default
661 2006-04-24 Raphael Neider <rneider AT web.de>
663 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
664 to config word, "pic14_"-prefixed some extern functions
665 (pic14_emitConfigWord): emit __config directive(s) if assignment to
666 config word has been found
667 * src/pic/device.h: added prototypes
668 * src/pic/pcode.c: added "pic14_"-prefix where needed
669 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
671 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

674 (pic14createInterruptVect): moved generating __config directives away

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

1003 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1004 (aopForSym, aopOp): increment asmop.allocated if reused,
1005 (freeAsmop): decrement asmop.allocated and check for zero instead of
1007 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1008 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

1032 2006-03-06 Borut Razem <borut.razem AT siol.net>
1034 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1035 made the linker quiet
1037 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1039 * src/pic16/gen.c (genPcall): fixed bug #1443644
1040 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1041 which dumps before the function entry point a data byte which represents
1042 the number of the local variables used by the specified function, added
1043 'xinst' for initial support for Extended Instruction Support,
1044 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1045 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1046 port->fun_prefix anymore (may change later),
1047 (genFunction, genEndFunction): do not store/restore local registers for
1048 _main (this should take care the --main-return command line option in
1050 (genOr): removed some legacy pic-port instructions,
1051 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1052 performing operations with SFR's causes data to be written more than
1053 once to each SFR. Perhaps SFRs should be handled in special cases...
1054 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1056 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1057 into account for stack starting position,

1059 --extended or -y for Extended Instruction Support,
1060 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1061 (deassignLRs): *** perhaps the most important change, old 'for' code
1062 (commented out for reference), didn't account for some registers which
1063 were left marked 'not free' after a pointer operation. The change
1064 reduces register usage a lot in some cases

3422 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
3424 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3426 * device/lib/printf_large.c: removed inline assembly for portability and
3427 readability. Use printf_fast if speed or size are more important.
3428 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3429 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3431 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3433 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3434 prevent compiler warning
3436 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3438 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3439 moved to level 0 and declared as static. Also they are explicit
3440 placed in access bank. This was necessery because some times they
3441 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3442 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3443 optimizations. Currently only compare to unsigned char is implemented,
3444 * src/pic16/gen.c: added fReturnIdx array,
3445 * (struct resolvedIfx) is moved to gen.h and made public,
3446 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3447 * (aopForSym): added an optimization to directly store in stack of
3448 the operand of a SEND iCode,
3449 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3450 but as registers instead (AOP_REG) using the fReturnIdx array,
3451 * (pic16_freeAsmop): remove the freed register from the
3452 _G.sregsAlloc field,
3453 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3454 a compare of 'WREG',
3455 * (pic16_popGetTempRegCond): changed function prototype, now
3456 function takes also a bitVector argument v which holds the current
3457 set of registers that are allocated for stack access by aopForSym,
3458 registers allocated in aopForSym for accessing stack symbols are not
3459 any more part of the functions usedRegs field,
3460 * (genCall): some times aopOp is called for a stack variable to be
3461 send, aopForSym might perform the push, if this is true make sure
3462 that genCall doesn't push the variable twice by testing _G.resDirect,
3463 * (genFunction): changed testing for unspecified interrupt number
3464 from 256 to INTNO_UNSPEC,
3465 * modified selection scheme of frame pointer generation. Previously
3466 if function did use local registers a frame pointer was generated,
3467 now a frame pointer is generated only if function has arguments
3468 (that need PLUSW2 register access), or has stack arguments, or the
3469 compiler is not instructed to omit the frame pointer,
3470 * (genEndFunction): before restoring local registers that were saved
3471 in the function preamble, also restore the registers that *might*
3472 have been allocated for stack access,
3473 * (genRet): removed some old comments,
3474 * (genCmp, the active (RN's) version): added a call to the
3475 pic16_genCmp_special function to perform the compare with a more
3476 robust and optimized way,
3477 * (genInline): a feature has been added in inline code generation,
3478 which allows a wildcard variable substitution when writing inline
3479 assembly. Code is incomplete and experimental therefore undocumented,
3480 * (genCast): changed order of aopOp for result and right to allow

4150 Adding support for replacing ljmps with sjmps in jumptables
4151 generated for switch statements. For now you need to set the
4152 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4153 Now 4 algorithms for mcs51 jumptable generation are used:
4154 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4155 addresses loaded pc-relative for up to 112 cases and stack-pushing
4156 target addresses loaded with offset from dptr for up to 256 cases.

4186 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4188 * added libc directory. The current version of LibC contains string
4189 functions, ctype functions and macros and some functions of the
4190 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4191 be extensively tested in the future. Standard disclaimer here.
4192 Library is not automatically build yet. But one can build it by
4193 invoking 'make' inside the libc directory.

4204 * (pic16_storeForReturn): optimized return of 0,
4205 * (genCmp): experimental code for new genCmp which uses PIC18's
4206 special compare&skip instructions. Initial tests fail some times
4207 with variables grater than 1 byte in size, so new code is disabled,
4208 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4210 * (genCast): began a fix to optimize the casting of a bit to another
4211 bit, now assigning a bitfield to another bitfield will fail, sorry,

4220 and 1 for banking instruction,
4221 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4222 caused stop processing pCodes after a inline assembly block,
4223 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4225 registers when it shouldn't,
4226 * src/pic16/ralloc.c (allocReg): add preliminary support for
4227 supporting a limited set of temporary registers,
4229 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4235 (genFunction): optimize RECEIVE iCodes in reentrant functions
4237 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7237 loaded with the linker search paths (-L arguments) and the libraries
7238 to be linked with the current source (-l arguments). Changes
7239 currently will affect only the pic16 port.
7240 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7241 include path the port specific paths and port specific libraries,
7242 * gplink command now contains the $3 argument,
7243 * src/pic16/device.h,
7244 * src/pic16/device.c,: structure PIC_device is made public and
7245 renamed to PIC16_device, the same for variable Pics which is renamed

7260 Documenting changes from previous commits.
7261 * configure.in (version 1.56),
7262 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7263 when generating output files to configure the pic16 library,
7264 but now I've commented it out, since gputils aren't installed in the
7265 SF compile farm, so library won't compile
7267 * device/lib/Makefile.in (version 1.56): initially I've added in
7268 target 'all' the prerequestive 'model-pic16' so it compiled the
7269 pic16 library, but now I've commented it out for the same reasons
7271 * added targets 'model-pic16' and 'objects-pic16' to compile the
7273 * added target 'port-specific-objects-pic16' to handle the
7274 generated libraries and copy them into the build/ directory
7275 * added target 'clean-intermediate-pic16' to clean intermediate
7276 files into pic16 directory
7277 * in target 'installdirs' added line to create directory pic16 in

7281 added lines to copy all header files to installation path,
7282 * in target 'installdirs' added line create directory for pic16
7283 headers in the installation path

7522 * src/SDCCast.c (decorateType),
7523 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
7524 LEFT_OP (left shift)
7526 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7528 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
7529 (default behaviour).
7531 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7533 A python script to validate compiler diagnostic messages. It can be
7534 used to verify that sdcc complains about bad c source code and
7535 gives a good location of the error.
7536 * support/valdiag/Makefile,
7537 * support/valdiag/valdiag.py,
7538 * support/valdiag/tests/*
7540 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7555 Bug reported from Jesus Calvino-Fraga
7557 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
7559 * sdcc.spec: updated
7560 * device/include/Makefile.in: don't install CVS directories
7561 * device/lib/Makefile.in: added removal of CVS directories after install
7562 * doc/Makefile: fixed install, added local_icons
7563 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
7564 * src/mcs51/gen.c (genRightShift): fixed bug #870788
7565 * src/ds390/gen.c (genRightShift): fixed bug #870788

7568 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7570 PIC16 port related changes:
7571 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7572 added variable stackPos,
7574 * gen.c: genCall, assignResultValue: added support for
7575 pushing/retrieving function parameters to/from stack,
7576 genFunction,genEndFunction: setup stack frame for the
7578 genAddrOf: will be changed according to bug 863624
7580 * added files genutils.c and genutils.h which contain gen*
7581 debugged and optimised functions extracted from gen.c
7583 * glue.c: added variable 'externs' which holds extern symbols,
7584 pic16emitRegularMap: is modified to properly handle relocatable
7585 symbols under the new scheme,
7586 pic16createInterruptVect: is modified
7587 pic16printPublics: is modified to emit 'global' assembler directives,
7588 added pic16_printExterns to print extern symbols,
7589 pic16glue: initializes stack/frame pointer in the beginning of
7590 the assembly output. Temporary hack, will be corrected later,
7591 because gplink yet does not support stack and SDCC does not
7592 yet support a type of crt0.o object to create the final binary.
7594 * Removed many lines that contain 8051 legacy code.
7595 * The code is finally placed under a 'code' directive.
7596 * Added port specific options.
7598 * _process_pragma: simplified since now we do not need *special*
7599 include file to define SFR registers. But a separate header
7600 will be needed. This will be developed later.
7601 * _pic16_parseOptions: added, parses port specific options:
7602 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7603 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7604 --preplace-udata-with=
7606 * _pic16_setDefaultOptions: modified to initialize section names,
7607 but hack is temporarly out of order since it needs improvement.
7608 * _pic16_genAssemblerPreamble: configuration words are emitted by
7609 their address instead of their name. This part is incomplete and
7610 supports only the 18Fxx2 devices. Other devices will emit an error
7611 during assembly since they do not contain the same set of config
7613 * _pic16_genIVT: is modified,
7615 * pcode.c: added definitions for some hardware registers that are needed
7617 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7618 All PCI entries are updated. Now LFSR is supported.
7619 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7620 * added pic16_newpCodeOpLit2 to support instructions with
7621 two literal arguments
7622 * pic16_pCode2str: corrected code that emits assembler instructions
7623 with two literal operands and those that have an access bit modifier
7624 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7625 this fixes a bug which caused some labels to be lost, when an
7626 assembler directive was added, i.e. banksel,
7627 * pic16_FixRegisterBanking: improved logic that causes the insertion
7629 * InlineFunction: functions that are called once, are not any more
7630 inlined. This can be a port option in the future,
7632 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7634 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7635 hold the corresponding uninitialized symbols,
7636 * pic16_allocProcessorRegister: registers have explicit marked the
7638 * pic16_allocInternalRegister: registers are explicit marked as
7640 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7641 processing list, so bit registers were lost,
7644 * ralloc.h: added field 'accessBank' and original symbol operand
7645 in register definition,
7646 * removed the field isMapped from register definition,
7648 ** Several functions have been removed from various sources:
7649 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7650 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7651 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7652 pic16_assignRelocatableRegisters
7654 ** others have been introduced:
7655 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7656 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7658 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7660 * support/scripts/inc2h.pl: changed definition of BIT_AT
7661 to emit 'sbit at' instead of 'bit at'. This was a request.
7663 PIC16 port related preliminary changes:
7664 * gen.c: prefixed function popRegFromString with
7665 pic16_ and all references to it corrected
7666 * pcode.c: all pic16_pc_* hardware registers prefixed
7667 with underscore (_),
7668 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7669 * ralloc.c: newReg(): when register is REG_SFR then
7670 set address to rIdx,
7671 pic16_allocProcessorRegister(): marks register wasUsed=0
7672 pic16_writeUsedRegs(): added a call to assign processor
7673 registers via pic16_assignFixedRegisters
7675 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7677 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7678 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7679 variables in unused register banks. Also the SSEG is placed
7680 wherever there is enough space for it, and IDATA can be anywhere
7681 in internal RAM. For now compile using -Wl-Y[stack_size].
7682 The mem file is different for this option as well, since it
7683 makes no sense of talking about DSEG lenght.
7685 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7687 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7688 in certain cases, e.g. when ROM assignment, patch provided
7689 from Albert den Haan.
7691 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7930 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7932 * src/SDCCast.c (decorateType): disabled a transformation I added in
7933 revision 1.188 (access to fields of a structure at an absolute address);
7934 it breaks with bitfields, extern declarations, and gcse analysis.
7935 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7936 could be assigned through a pointer, so don't complain.
7937 * src/SDCCast.c (astErrors),
7939 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
7941 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

8692 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8693 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8694 fetching of the pointer
8695 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8696 copied from genNearPointerSet()
8697 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8698 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8714 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8715 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8716 type for bits was changed. It resulted in bit variables becoming
8717 global, which is not permitted in PIC 14 assembly output.
8719 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

8734 A few small changes that speed up the peephole optimizer.
8738 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8740 Try to make the peephole optimizer smarter by maintaining
8741 an association between the assembly source code and the
8742 iCodes that originated them. Put this information to use
8743 with a new peephole rule condition "notVolatile" so that
8744 the rules can be aggressive yet still safe.
8749 * src/mcs51/peeph.def
8751 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8755 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8756 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8757 if the left or right operand symbols have the accuse flag set.
8759 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8761 Changed the type of the result of the ! (NOT) operator to char;
8762 previously it returned the same type as the source. This allows
8763 us to eliminate all the genFloatNot functions (all of its target
8764 implementations were very buggy) since !float can use the same

8777 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8778 during interrupts. Ensure WSAVE is located at a shared bank address.
8779 2. Fixed page selection in some places
8780 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8781 the registers name strings.
8782 4. Fixed "signed / unsigned compare" compiler warnings.
8783 5. The PIC port manages its own allocation of the general purpose
8784 registers, but makes no attempt to reuse them. As a result when
8785 compiling it soon runs out of general purpose registers. Some
8786 additional code was added to the files pcode.c and device.c to walk
8787 through the function call tree and rename the registers so that they
8797 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8804 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8806 Made bitfield a distinct type from bit so that bitfields
8807 convert as per ANSI C and bits retain their traditional
8808 boolean style behaviour. Implemented bitfield support in
8816 * src/ds390/gen.c: bit v bitfield split
8817 * src/z80/gen.c: New support for bitfields
8818 * support/regression/tests/bitfields.c: reenabled z80,
8821 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8823 Rules 246.x, 247.x relate to bitfields, the others speed up
8824 access to xdata mapped I/O devices.
8826 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8828 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8830 Cleaned up genPackBits and genUnpackBits and added two helper
8831 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8832 for literal assignments in genPackBits (thanks to Frieder for
8838 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8840 Fixed bug #748310 (pointer to function type mishandled when the
8841 function name is omitted). Also fixed a SIGSEGV when a function
8842 attribute (reentrant, etc) is used on a non-function or on a
8843 function but misplaced before the parameter list.
8845 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8847 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8848 * support/Util/SDCCerr.h,

8870 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8872 Made the constant following the "interrupt" keyword optional. If
8873 omitted, the function will not automatically be given an entry
8874 in the interrupt vector table (similar to #pragma NOIV, but
8875 less syntacticly kludgy). The interrupt number is also now
8876 range checked. Also fixed a bug in the high order bit example

9406 added if/endif conditional macros to remove options help
9407 messages from optionsTable when a port is not configured, added
9408 support for the PIc16 port in the ports table, when executing
9409 the compiler with no port specified on command line, a default
9410 port is selected with the new macro DEFAULT_PORT which is
9411 defined in port.h, in setDefaultOptions() linkOptions is removed
9412 from initialization assignment, since now it is a set,
9413 parseCmdLine uses setParseWithComma for linkOptions, in
9414 linkEdit() linkOptions are accessed with new function indexSet()
9415 which returns the i'th item of a set variable. See SDCCset.c, in
9416 linkEdit() when calling buildCmdLine(), added linkOptions as
9417 last argument. Now users can pass arguments to gplink via the
9418 -Wl option, main() uses pic16glue() to glue up pic16 programs

9432 gpasm complaining and test the linkage with gplink, _linkCmd and
9433 _asmCmd changed to be more gplink and gpasm friendly
9434 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9435 produced an error when parsed, peep rule 12 is added to utilize
9436 movff, but it is commented out since the pCode does not support
9437 yet a command with 2 address arguments
9439 2003-05-18 <johan AT balder>
9441 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10500 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10502 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10504 * in \sdcc\as\mcs51\ changed these files in order to create an
10505 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10506 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10507 following files to include the previous two files: aslink.dsp,
10508 Makefile.aslink, Makefile.bcc, and Makefile.in.
10510 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10511 .adb instead of .cdb
10513 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10515 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10516 value from option --iram-size.
10518 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10520 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10523 2002-09-18 <wiml AT hhhh.org>
10525 * SDCClrange.h: exposed setFromRange() and setToRange()
10526 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10527 packRegsForAccUse() (bug 542397)
10528 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10529 multiple times and emitting the fetch operations more than once
10530 added aopGetUsesAcc() function to allow binary operators to
10531 fetch their operands in the correct order; made genMinus() emit
10532 compact code for X = LITERAL - Y
10534 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10535 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10536 sprintf() in line 1267.
10538 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10539 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10542 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10543 Changes to aslink (All the changes are marked with 'JCF'):
10545 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10548 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10549 area BSEG. Also moves, if possible, the DATA area down into the internal
10550 ram so more space is available.
10552 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10555 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10556 not bytes. Function summary() which creates a memory usage summary
10557 file with extension .mem. Reports of overlaping stack and small stack
10558 size. If the space for the stack is less than 16 bytes aslink trows a
10561 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10562 the 8051. Option 'y' for memory summary output file.
10564 Changes to sdcc (All the changes are marked with 'JCF'):
10566 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10568 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10569 overlaying area for it (uses RegBankUsed[4]).
10571 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10572 bank zero as used by default. By default aslink locates the stack
10573 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10574 the creation of the .mem file. Delegates the allocation of data area
10575 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10576 the begining of the stack area to aslink.
10578 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10579 glue() in SDCCglue.c creates an area for it.
10581 2002-09-03 Borut Razem <borut.razem AT siol.net>
10582 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10583 sdcc/src/pic/glue.c:
10584 introduced atexit() handler for teporay files removal in case of
10585 errors, assertions, ...
10587 2002-08-29 Borut Razem <borut.razem AT siol.net>
10588 * sdcc/support/cpp2/auto-host_vc_in.h:
10589 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10590 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10591 Maybe there is a similar problem with BORLANDC? It should be checked!
10593 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10594 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10595 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10596 was not executed, and the compiler (cl) launched a warning:
10597 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10599 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10600 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10602 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10603 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10605 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10606 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10607 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10608 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10609 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10610 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10611 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10612 - added Release configuration in VS projects
10613 - review of compiler an linker options
10614 - VC .exe files are generated in bin_vc directory, not to interfere
10615 with binaries generated from other projects (cygwin, mingw, bcc ...)
10617 * sdcc/src/yacc.dsp: added
10619 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10620 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10621 and insert the version number definitions from .version
10623 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10625 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10626 added - genarate auto-host.h using auto-host_vc_in.h as template
10629 removed from CVS, generated automatically
10631 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10632 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10634 2002-08-11 Borut Razem <borut.razem AT siol.net>
10635 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10637 2002-08-10 Borut Razem <borut.razem AT siol.net>
10638 * src/SDCCmain.c (main):
10639 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10640 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10641 The consequence was that some temporary files were not removed.
10644 unification of code in functions tempfilename() and tempfile():
10645 function tempnam() is defined in Visual Studio 6.0 and .NET
10647 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10649 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10650 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10651 - removed compiler command line option /WX: Treats all warnings as errors
10652 - update a list of source files, included into the project
10654 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10655 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10656 changed project type to Generic Project so that can be correcly converted to VS.NET project
10658 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10660 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10662 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10664 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10665 added return 0 statements after assert() to make compiler happy
10667 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10668 added newline in the def file to keep MSC compiler satisfied
10670 * sdcc/src/z80/gen.c:
10671 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10672 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10673 - solved MSC error in function aopDump()
10675 * sdcc_vc.h: define PREFIX as "\\sdcc"
10677 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10678 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10681 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10682 - Rewrote the register banking algorithm.
10683 - Added pCode live-range analysis to registers (for now, only non-used and
10684 singly-used registers optimized away)
10686 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10688 * 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.

10719 * src/SDCCval.c: fixed bug #532436
10721 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10723 Added "char *Processor" field to the port structure.
10726 Added -p option. Allows port dependent processor to be specified.
10729 Initialized the new field char *Processor field to NULL in all ports
10732 Compiler generated registers for interrupt context saving
10733 were not getting allocated.
10735 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10738 Fixed left shift. Will promote the left side of a left shift
10739 if a) left shifting more than size of operand or b) when assigned
10740 to something size > size of left side
10742 2002-03-14 Scott Dattalo <scott AT dattalo.com>

10853 Previous fix was not good. basic blocks that have "break" or "return" are
10854 not really partof a loop , but live ranges used in these blocks should
10855 be live thru the entire loop, so set partOfLoop but don't add them to
