105 and enabled nesting of critical functions though not for gbz80
106 (genCritical, genEndCritical): added functions
107 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
108 * src/z80/mappings.i: added "ei" to all mappings

114 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
115 archive with gcc 4.1 on mips and wrote the patch"
117 2006-03-16 Raphael Neider <rneider AT web.de>
119 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
120 the left operand is shorter than the result (c* = lit-c* + int),
122 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
125 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
127 * src/.version: increased version number to 2.5.5
128 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
129 linking is done manually in pic16 port's _linkEdit,
130 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
131 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
132 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
133 allocate asmop as AOP_ACC,
134 (aopForRemat): added parameter 'bool result' in function declaration,
135 (pic16_aopGet): return AOP_ACC when accessing WREG,

147 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
148 call to allocReg, not by manually allocating a new one,
149 (pic16_assignRegisters): now before going through the register
150 allocating functions mark all registers as free. This eliminates some
151 side effects resulting from peephole parser done earlier in the backbone
153 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

211 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
212 which dumps before the function entry point a data byte which represents
213 the number of the local variables used by the specified function, added
214 'xinst' for initial support for Extended Instruction Support,
215 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
216 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
217 port->fun_prefix anymore (may change later),
218 (genFunction, genEndFunction): do not store/restore local registers for
219 _main (this should take care the --main-return command line option in
221 (genOr): removed some legacy pic-port instructions,
222 * src/pic16/genarith.c (genAddLit): re-enabled old code because
223 performing operations with SFR's causes data to be written more than
224 once to each SFR. Perhaps SFRs should be handled in special cases...
225 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
227 * src/pic16/main.c (_process_pragma): stack bound checking did not take
228 into account for stack starting position,
229 (struct OPTIONS pic16_optionsTable): added command line argument
230 --extended or -y for Extended Instruction Support,
231 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
232 (deassignLRs): *** perhaps the most important change, old 'for' code
233 (commented out for reference), didn't account for some registers which
234 were left marked 'not free' after a pointer operation. The change
235 reduces register usage a lot in some cases

2585 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2587 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
2590 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2592 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
2593 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2595 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2597 * device/lib/printf_large.c: removed inline assembly for portability and
2598 readability. Use printf_fast if speed or size are more important.
2599 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2600 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2602 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2604 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2605 prevent compiler warning
2607 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2609 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2610 moved to level 0 and declared as static. Also they are explicit
2611 placed in access bank. This was necessery because some times they
2612 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2613 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2614 optimizations. Currently only compare to unsigned char is implemented,
2615 * src/pic16/gen.c: added fReturnIdx array,
2616 * (struct resolvedIfx) is moved to gen.h and made public,
2617 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2618 * (aopForSym): added an optimization to directly store in stack of
2619 the operand of a SEND iCode,
2620 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2621 but as registers instead (AOP_REG) using the fReturnIdx array,
2622 * (pic16_freeAsmop): remove the freed register from the
2623 _G.sregsAlloc field,
2624 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2625 a compare of 'WREG',
2626 * (pic16_popGetTempRegCond): changed function prototype, now
2627 function takes also a bitVector argument v which holds the current
2628 set of registers that are allocated for stack access by aopForSym,
2629 registers allocated in aopForSym for accessing stack symbols are not
2630 any more part of the functions usedRegs field,
2631 * (genCall): some times aopOp is called for a stack variable to be
2632 send, aopForSym might perform the push, if this is true make sure
2633 that genCall doesn't push the variable twice by testing _G.resDirect,
2634 * (genFunction): changed testing for unspecified interrupt number
2635 from 256 to INTNO_UNSPEC,
2636 * modified selection scheme of frame pointer generation. Previously
2637 if function did use local registers a frame pointer was generated,
2638 now a frame pointer is generated only if function has arguments
2639 (that need PLUSW2 register access), or has stack arguments, or the
2640 compiler is not instructed to omit the frame pointer,
2641 * (genEndFunction): before restoring local registers that were saved
2642 in the function preamble, also restore the registers that *might*
2643 have been allocated for stack access,
2644 * (genRet): removed some old comments,
2645 * (genCmp, the active (RN's) version): added a call to the
2646 pic16_genCmp_special function to perform the compare with a more
2647 robust and optimized way,
2648 * (genInline): a feature has been added in inline code generation,
2649 which allows a wildcard variable substitution when writing inline
2650 assembly. Code is incomplete and experimental therefore undocumented,
2651 * (genCast): changed order of aopOp for result and right to allow
2652 aopForSym to directly load the result if possible,
2653 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2654 perform an optimized compare on some selected special occasions,
2655 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2656 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2657 generate an IVT any more,
2658 * src/pic16/main.c (pic16_optionsTable): added command line option
2660 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2661 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2663 * src/pic16/NOTES: Raphael Neider added in list of active developers
2664 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2665 jumptable_end to prevent bug #,
2666 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2667 inCond and outCond fields,
2668 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2669 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2670 turn off register spilling,
2671 * (packRegsForOneUse): synced with other ports' versions although it
2672 is not used currently,
2673 * (pic16_packRegisters): added an optimization while reading
2674 structure bitfields, some registers may be saved (malloc code is
2675 decreased by 80 bytes)
2677 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2679 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2680 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2681 this can be optimized more?
2683 2005-03-10 Raphael Neider <rneider AT web.de>
2685 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2686 genNearPointerGet): (hopefully) fixed access to bitfields via
2687 pointers (p->bitN = x; and x = p->bitN; failed)
2689 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2732 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
2733 to keep the correct label reference count when adding/removing references
2734 to labels. A peephole file using this is appended to patch #1144962.

3013 access stack and frame pointers. They are initially assigned to
3014 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
3015 accessing SFRs. Updated all occurences of modification of stack or
3016 frame pointer in gen.c and pcode.c,
3017 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with

3322 generated for switch statements. For now you need to set the
3323 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3324 Now 4 algorithms for mcs51 jumptable generation are used:
3325 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3359 * added libc directory. The current version of LibC contains string
3360 functions, ctype functions and macros and some functions of the
3361 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3362 be extensively tested in the future. Standard disclaimer here.

3375 * (pic16_storeForReturn): optimized return of 0,
3376 * (genCmp): experimental code for new genCmp which uses PIC18's
3377 special compare&skip instructions. Initial tests fail some times
3378 with variables grater than 1 byte in size, so new code is disabled,
3379 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3381 * (genCast): began a fix to optimize the casting of a bit to another
3382 bit, now assigning a bitfield to another bitfield will fail, sorry,

3396 registers when it shouldn't,
3397 * src/pic16/ralloc.c (allocReg): add preliminary support for
3398 supporting a limited set of temporary registers,
3400 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6407 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6408 loaded with the linker search paths (-L arguments) and the libraries
6409 to be linked with the current source (-l arguments). Changes
6410 currently will affect only the pic16 port.
6411 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6412 include path the port specific paths and port specific libraries,
6413 * gplink command now contains the $3 argument,
6414 * src/pic16/device.h,
6415 * src/pic16/device.c,: structure PIC_device is made public and

6431 Documenting changes from previous commits.
6432 * configure.in (version 1.56),
6433 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6434 when generating output files to configure the pic16 library,
6435 but now I've commented it out, since gputils aren't installed in the
6436 SF compile farm, so library won't compile
6438 * device/lib/Makefile.in (version 1.56): initially I've added in
6439 target 'all' the prerequestive 'model-pic16' so it compiled the
6440 pic16 library, but now I've commented it out for the same reasons
6442 * added targets 'model-pic16' and 'objects-pic16' to compile the
6444 * added target 'port-specific-objects-pic16' to handle the
6445 generated libraries and copy them into the build/ directory
6446 * added target 'clean-intermediate-pic16' to clean intermediate
6447 files into pic16 directory
6448 * in target 'installdirs' added line to create directory pic16 in

6452 added lines to copy all header files to installation path,
6453 * in target 'installdirs' added line create directory for pic16
6454 headers in the installation path

6470 option so that it actually works. Made it specific to the z80, since
6471 the gbz80 doesn't have these kinds of I/O ports.
6473 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6475 * device/include/z180.h,

6582 UPPER for immediate operands,
6583 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6585 * src/pic16/peeph.def: all peepholes with movff are commented out,
6586 because there is a problem in the pcode peep optimizer,
6587 * src/pic16/ralloc.c: the register allocator can now reuse local
6588 function symbols for another function. This saves register usage.
6589 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6591 Added file src/pic16/NOTES with information about program writing on
6592 the current port version.

6697 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6699 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6700 (default behaviour).
6702 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6704 A python script to validate compiler diagnostic messages. It can be
6705 used to verify that sdcc complains about bad c source code and
6706 gives a good location of the error.
6707 * support/valdiag/Makefile,
6708 * support/valdiag/valdiag.py,

6728 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6730 * sdcc.spec: updated
6731 * device/include/Makefile.in: don't install CVS directories
6732 * device/lib/Makefile.in: added removal of CVS directories after install
6733 * doc/Makefile: fixed install, added local_icons
6734 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
6735 * src/mcs51/gen.c (genRightShift): fixed bug #870788
6736 * src/ds390/gen.c (genRightShift): fixed bug #870788

6739 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6741 PIC16 port related changes:
6742 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6743 added variable stackPos,
6745 * gen.c: genCall, assignResultValue: added support for
6746 pushing/retrieving function parameters to/from stack,
6747 genFunction,genEndFunction: setup stack frame for the
6749 genAddrOf: will be changed according to bug 863624
6751 * added files genutils.c and genutils.h which contain gen*
6752 debugged and optimised functions extracted from gen.c
6754 * glue.c: added variable 'externs' which holds extern symbols,
6755 pic16emitRegularMap: is modified to properly handle relocatable
6756 symbols under the new scheme,
6757 pic16createInterruptVect: is modified
6758 pic16printPublics: is modified to emit 'global' assembler directives,
6759 added pic16_printExterns to print extern symbols,
6760 pic16glue: initializes stack/frame pointer in the beginning of
6761 the assembly output. Temporary hack, will be corrected later,
6762 because gplink yet does not support stack and SDCC does not
6763 yet support a type of crt0.o object to create the final binary.
6765 * Removed many lines that contain 8051 legacy code.
6766 * The code is finally placed under a 'code' directive.
6767 * Added port specific options.
6769 * _process_pragma: simplified since now we do not need *special*
6770 include file to define SFR registers. But a separate header
6771 will be needed. This will be developed later.
6772 * _pic16_parseOptions: added, parses port specific options:
6773 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6774 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6775 --preplace-udata-with=
6777 * _pic16_setDefaultOptions: modified to initialize section names,
6778 but hack is temporarly out of order since it needs improvement.
6779 * _pic16_genAssemblerPreamble: configuration words are emitted by
6780 their address instead of their name. This part is incomplete and
6781 supports only the 18Fxx2 devices. Other devices will emit an error
6782 during assembly since they do not contain the same set of config
6784 * _pic16_genIVT: is modified,
6786 * pcode.c: added definitions for some hardware registers that are needed
6788 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6789 All PCI entries are updated. Now LFSR is supported.
6790 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6791 * added pic16_newpCodeOpLit2 to support instructions with
6792 two literal arguments
6793 * pic16_pCode2str: corrected code that emits assembler instructions
6794 with two literal operands and those that have an access bit modifier
6795 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6796 this fixes a bug which caused some labels to be lost, when an
6797 assembler directive was added, i.e. banksel,
6798 * pic16_FixRegisterBanking: improved logic that causes the insertion
6800 * InlineFunction: functions that are called once, are not any more
6801 inlined. This can be a port option in the future,
6803 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6805 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6806 hold the corresponding uninitialized symbols,
6807 * pic16_allocProcessorRegister: registers have explicit marked the
6809 * pic16_allocInternalRegister: registers are explicit marked as
6811 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6812 processing list, so bit registers were lost,
6815 * ralloc.h: added field 'accessBank' and original symbol operand
6816 in register definition,
6817 * removed the field isMapped from register definition,
6819 ** Several functions have been removed from various sources:
6820 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6821 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6822 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6823 pic16_assignRelocatableRegisters
6825 ** others have been introduced:
6826 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6827 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6829 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6831 * support/scripts/inc2h.pl: changed definition of BIT_AT
6832 to emit 'sbit at' instead of 'bit at'. This was a request.
6834 PIC16 port related preliminary changes:
6835 * gen.c: prefixed function popRegFromString with
6836 pic16_ and all references to it corrected
6837 * pcode.c: all pic16_pc_* hardware registers prefixed
6838 with underscore (_),
6839 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6840 * ralloc.c: newReg(): when register is REG_SFR then
6841 set address to rIdx,
6842 pic16_allocProcessorRegister(): marks register wasUsed=0
6843 pic16_writeUsedRegs(): added a call to assign processor
6844 registers via pic16_assignFixedRegisters
6846 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6848 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6849 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6850 variables in unused register banks. Also the SSEG is placed
6851 wherever there is enough space for it, and IDATA can be anywhere
6852 in internal RAM. For now compile using -Wl-Y[stack_size].
6853 The mem file is different for this option as well, since it
6854 makes no sense of talking about DSEG lenght.
6856 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6858 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6859 in certain cases, e.g. when ROM assignment, patch provided
6860 from Albert den Haan.
6862 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7750 to xdata int at 0x1234 tempvar = 1.
7751 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7752 provided by Akiya ISHIDA

7863 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7864 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7865 fetching of the pointer
7866 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7867 copied from genNearPointerSet()
7868 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7869 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7870 If they pop r0/r1 they must be called in the opposite order than aopOp().

7881 these ports have their own __sdcc_external_start()
7883 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7885 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7886 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7887 type for bits was changed. It resulted in bit variables becoming
7888 global, which is not permitted in PIC 14 assembly output.
7890 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7905 A few small changes that speed up the peephole optimizer.
7909 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7911 Try to make the peephole optimizer smarter by maintaining
7912 an association between the assembly source code and the
7913 iCodes that originated them. Put this information to use
7914 with a new peephole rule condition "notVolatile" so that
7915 the rules can be aggressive yet still safe.
7920 * src/mcs51/peeph.def
7922 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7926 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7927 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7928 if the left or right operand symbols have the accuse flag set.
7930 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7932 Changed the type of the result of the ! (NOT) operator to char;
7933 previously it returned the same type as the source. This allows
7934 us to eliminate all the genFloatNot functions (all of its target
7935 implementations were very buggy) since !float can use the same
7938 * src/SDCCicode.c (ast2iCode): ! returns char

7947 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7948 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7949 during interrupts. Ensure WSAVE is located at a shared bank address.
7950 2. Fixed page selection in some places
7951 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7952 the registers name strings.
7953 4. Fixed "signed / unsigned compare" compiler warnings.
7954 5. The PIC port manages its own allocation of the general purpose
7955 registers, but makes no attempt to reuse them. As a result when
7956 compiling it soon runs out of general purpose registers. Some
7957 additional code was added to the files pcode.c and device.c to walk
7958 through the function call tree and rename the registers so that they
7968 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7969 genPlus() & genMinus() when the result is the same as left or right

7975 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7977 Made bitfield a distinct type from bit so that bitfields
7978 convert as per ANSI C and bits retain their traditional
7979 boolean style behaviour. Implemented bitfield support in
7987 * src/ds390/gen.c: bit v bitfield split
7988 * src/z80/gen.c: New support for bitfields
7989 * support/regression/tests/bitfields.c: reenabled z80,
7992 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7994 Rules 246.x, 247.x relate to bitfields, the others speed up
7995 access to xdata mapped I/O devices.
7997 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7999 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8001 Cleaned up genPackBits and genUnpackBits and added two helper
8002 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8003 for literal assignments in genPackBits (thanks to Frieder for
8009 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8011 Fixed bug #748310 (pointer to function type mishandled when the
8012 function name is omitted). Also fixed a SIGSEGV when a function
8013 attribute (reentrant, etc) is used on a non-function or on a
8014 function but misplaced before the parameter list.
8016 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8018 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8019 * support/Util/SDCCerr.h,

8041 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8043 Made the constant following the "interrupt" keyword optional. If
8044 omitted, the function will not automatically be given an entry
8045 in the interrupt vector table (similar to #pragma NOIV, but
8046 less syntacticly kludgy). The interrupt number is also now
8047 range checked. Also fixed a bug in the high order bit example

8061 * src/SDCCicode.c (operandOperation): rewritten some ops
8062 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8063 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8065 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8066 be re-activated by defining REDUCE_LITERALS)

8068 unsigned, but are signed by default
8069 * src/SDCCval.c (constVal): rearranged
8070 * src/SDCCval.c (valMod): preliminary fix
8071 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8577 added if/endif conditional macros to remove options help
8578 messages from optionsTable when a port is not configured, added
8579 support for the PIc16 port in the ports table, when executing
8580 the compiler with no port specified on command line, a default
8581 port is selected with the new macro DEFAULT_PORT which is
8582 defined in port.h, in setDefaultOptions() linkOptions is removed
8583 from initialization assignment, since now it is a set,
8584 parseCmdLine uses setParseWithComma for linkOptions, in
8585 linkEdit() linkOptions are accessed with new function indexSet()
8586 which returns the i'th item of a set variable. See SDCCset.c, in
8587 linkEdit() when calling buildCmdLine(), added linkOptions as
8588 last argument. Now users can pass arguments to gplink via the
8589 -Wl option, main() uses pic16glue() to glue up pic16 programs

8602 * src/pic16/main.c: __config directives are commented out to stop
8603 gpasm complaining and test the linkage with gplink, _linkCmd and
8604 _asmCmd changed to be more gplink and gpasm friendly
8605 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8606 produced an error when parsed, peep rule 12 is added to utilize
8607 movff, but it is commented out since the pCode does not support
8608 yet a command with 2 address arguments
8610 2003-05-18 <johan AT balder>
8612 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9653 2003-01-04 <johan AT balder>
9655 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9657 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9670 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9671 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9673 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9675 * in \sdcc\as\mcs51\ changed these files in order to create an
9676 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9677 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9678 following files to include the previous two files: aslink.dsp,
9679 Makefile.aslink, Makefile.bcc, and Makefile.in.
9681 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9682 .adb instead of .cdb
9684 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9686 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9687 value from option --iram-size.
9689 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9691 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9694 2002-09-18 <wiml AT hhhh.org>
9696 * SDCClrange.h: exposed setFromRange() and setToRange()
9697 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9698 packRegsForAccUse() (bug 542397)
9699 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9700 multiple times and emitting the fetch operations more than once
9701 added aopGetUsesAcc() function to allow binary operators to
9702 fetch their operands in the correct order; made genMinus() emit
9703 compact code for X = LITERAL - Y
9705 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9706 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9707 sprintf() in line 1267.
9709 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9710 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9713 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9714 Changes to aslink (All the changes are marked with 'JCF'):
9716 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9719 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9720 area BSEG. Also moves, if possible, the DATA area down into the internal
9721 ram so more space is available.
9723 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9726 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9727 not bytes. Function summary() which creates a memory usage summary
9728 file with extension .mem. Reports of overlaping stack and small stack
9729 size. If the space for the stack is less than 16 bytes aslink trows a
9732 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9733 the 8051. Option 'y' for memory summary output file.
9735 Changes to sdcc (All the changes are marked with 'JCF'):
9737 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9739 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9740 overlaying area for it (uses RegBankUsed[4]).
9742 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9743 bank zero as used by default. By default aslink locates the stack
9744 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9745 the creation of the .mem file. Delegates the allocation of data area
9746 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9747 the begining of the stack area to aslink.
9749 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9750 glue() in SDCCglue.c creates an area for it.
9752 2002-09-03 Borut Razem <borut.razem AT siol.net>
9753 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9754 sdcc/src/pic/glue.c:
9755 introduced atexit() handler for teporay files removal in case of
9756 errors, assertions, ...
9758 2002-08-29 Borut Razem <borut.razem AT siol.net>
9759 * sdcc/support/cpp2/auto-host_vc_in.h:
9760 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9761 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9762 Maybe there is a similar problem with BORLANDC? It should be checked!
9764 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9765 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9766 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9767 was not executed, and the compiler (cl) launched a warning:
9768 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9770 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9771 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9773 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9774 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9776 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9777 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9778 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9779 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9780 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9781 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9782 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9783 - added Release configuration in VS projects
9784 - review of compiler an linker options
9785 - VC .exe files are generated in bin_vc directory, not to interfere
9786 with binaries generated from other projects (cygwin, mingw, bcc ...)
9788 * sdcc/src/yacc.dsp: added
9790 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9791 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9792 and insert the version number definitions from .version
9794 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9796 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9797 added - genarate auto-host.h using auto-host_vc_in.h as template
9800 removed from CVS, generated automatically
9802 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9803 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9805 2002-08-11 Borut Razem <borut.razem AT siol.net>
9806 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9808 2002-08-10 Borut Razem <borut.razem AT siol.net>
9809 * src/SDCCmain.c (main):
9810 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9811 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9812 The consequence was that some temporary files were not removed.
9815 unification of code in functions tempfilename() and tempfile():
9816 function tempnam() is defined in Visual Studio 6.0 and .NET
9818 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9820 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9821 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9822 - removed compiler command line option /WX: Treats all warnings as errors
9823 - update a list of source files, included into the project
9825 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9826 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9827 changed project type to Generic Project so that can be correcly converted to VS.NET project
9829 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9831 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9833 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9835 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9836 added return 0 statements after assert() to make compiler happy
9838 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9839 added newline in the def file to keep MSC compiler satisfied
9841 * sdcc/src/z80/gen.c:
9842 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9843 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9844 - solved MSC error in function aopDump()
9846 * sdcc_vc.h: define PREFIX as "\\sdcc"
9848 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9849 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9851 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9852 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9853 - Rewrote the register banking algorithm.
9854 - Added pCode live-range analysis to registers (for now, only non-used and
9855 singly-used registers optimized away)
9857 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9859 * 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.

9888 2002-03-28 Johan Knol <johan AT balder>
9890 * src/SDCCval.c: fixed bug #532436
9892 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9894 Added "char *Processor" field to the port structure.
9897 Added -p option. Allows port dependent processor to be specified.
9900 Initialized the new field char *Processor field to NULL in all ports
9903 Compiler generated registers for interrupt context saving
9904 were not getting allocated.
9906 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9909 Fixed left shift. Will promote the left side of a left shift
9910 if a) left shifting more than size of operand or b) when assigned
9911 to something size > size of left side
9913 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9915 tons of changes. Register allocation has been
9916 rewritten. Added customization for the various PICs. Flow
9917 analysis is restructured. ...
9923 Added. device.c is a PIC port hack to accomodate variations
9926 2002-03-13 Michael Hope <michaelh AT vroom>
9928 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
