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

110 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
111 archive with gcc 4.1 on mips and wrote the patch"
113 2006-03-16 Raphael Neider <rneider AT web.de>
115 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
116 the left operand is shorter than the result (c* = lit-c* + int),
118 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
121 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
123 * src/.version: increased version number to 2.5.5
124 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
125 linking is done manually in pic16 port's _linkEdit,
126 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
127 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
128 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
129 allocate asmop as AOP_ACC,
130 (aopForRemat): added parameter 'bool result' in function declaration,
131 (pic16_aopGet): return AOP_ACC when accessing WREG,

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

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

2581 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2583 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
2586 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2588 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
2589 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2591 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2593 * device/lib/printf_large.c: removed inline assembly for portability and
2594 readability. Use printf_fast if speed or size are more important.
2595 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2596 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2598 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2600 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2601 prevent compiler warning
2603 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2605 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2606 moved to level 0 and declared as static. Also they are explicit
2607 placed in access bank. This was necessery because some times they
2608 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2609 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2610 optimizations. Currently only compare to unsigned char is implemented,
2611 * src/pic16/gen.c: added fReturnIdx array,
2612 * (struct resolvedIfx) is moved to gen.h and made public,
2613 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2614 * (aopForSym): added an optimization to directly store in stack of
2615 the operand of a SEND iCode,
2616 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2617 but as registers instead (AOP_REG) using the fReturnIdx array,
2618 * (pic16_freeAsmop): remove the freed register from the
2619 _G.sregsAlloc field,
2620 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2621 a compare of 'WREG',
2622 * (pic16_popGetTempRegCond): changed function prototype, now
2623 function takes also a bitVector argument v which holds the current
2624 set of registers that are allocated for stack access by aopForSym,
2625 registers allocated in aopForSym for accessing stack symbols are not
2626 any more part of the functions usedRegs field,
2627 * (genCall): some times aopOp is called for a stack variable to be
2628 send, aopForSym might perform the push, if this is true make sure
2629 that genCall doesn't push the variable twice by testing _G.resDirect,
2630 * (genFunction): changed testing for unspecified interrupt number
2631 from 256 to INTNO_UNSPEC,
2632 * modified selection scheme of frame pointer generation. Previously
2633 if function did use local registers a frame pointer was generated,
2634 now a frame pointer is generated only if function has arguments
2635 (that need PLUSW2 register access), or has stack arguments, or the
2636 compiler is not instructed to omit the frame pointer,
2637 * (genEndFunction): before restoring local registers that were saved
2638 in the function preamble, also restore the registers that *might*
2639 have been allocated for stack access,
2640 * (genRet): removed some old comments,
2641 * (genCmp, the active (RN's) version): added a call to the
2642 pic16_genCmp_special function to perform the compare with a more
2643 robust and optimized way,
2644 * (genInline): a feature has been added in inline code generation,
2645 which allows a wildcard variable substitution when writing inline
2646 assembly. Code is incomplete and experimental therefore undocumented,
2647 * (genCast): changed order of aopOp for result and right to allow
2648 aopForSym to directly load the result if possible,
2649 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2650 perform an optimized compare on some selected special occasions,
2651 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2652 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2653 generate an IVT any more,
2654 * src/pic16/main.c (pic16_optionsTable): added command line option
2656 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2657 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2659 * src/pic16/NOTES: Raphael Neider added in list of active developers
2660 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2661 jumptable_end to prevent bug #,
2662 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2663 inCond and outCond fields,
2664 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2665 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2666 turn off register spilling,
2667 * (packRegsForOneUse): synced with other ports' versions although it
2668 is not used currently,
2669 * (pic16_packRegisters): added an optimization while reading
2670 structure bitfields, some registers may be saved (malloc code is
2671 decreased by 80 bytes)
2673 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2675 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2676 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2677 this can be optimized more?
2679 2005-03-10 Raphael Neider <rneider AT web.de>
2681 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2682 genNearPointerGet): (hopefully) fixed access to bitfields via
2683 pointers (p->bitN = x; and x = p->bitN; failed)
2685 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

2728 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
2729 to keep the correct label reference count when adding/removing references
2730 to labels. A peephole file using this is appended to patch #1144962.

3009 access stack and frame pointers. They are initially assigned to
3010 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
3011 accessing SFRs. Updated all occurences of modification of stack or
3012 frame pointer in gen.c and pcode.c,
3013 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with

3318 generated for switch statements. For now you need to set the
3319 environment variable SDCC_SJMP_JUMPTABLE to enable this.
3320 Now 4 algorithms for mcs51 jumptable generation are used:
3321 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

3355 * added libc directory. The current version of LibC contains string
3356 functions, ctype functions and macros and some functions of the
3357 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
3358 be extensively tested in the future. Standard disclaimer here.

3372 * (genCmp): experimental code for new genCmp which uses PIC18's
3373 special compare&skip instructions. Initial tests fail some times
3374 with variables grater than 1 byte in size, so new code is disabled,
3375 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
3377 * (genCast): began a fix to optimize the casting of a bit to another
3378 bit, now assigning a bitfield to another bitfield will fail, sorry,

3392 registers when it shouldn't,
3393 * src/pic16/ralloc.c (allocReg): add preliminary support for
3394 supporting a limited set of temporary registers,
3396 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6403 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
6404 loaded with the linker search paths (-L arguments) and the libraries
6405 to be linked with the current source (-l arguments). Changes
6406 currently will affect only the pic16 port.
6407 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6408 include path the port specific paths and port specific libraries,
6409 * gplink command now contains the $3 argument,
6410 * src/pic16/device.h,
6411 * src/pic16/device.c,: structure PIC_device is made public and

6427 Documenting changes from previous commits.
6428 * configure.in (version 1.56),
6429 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6430 when generating output files to configure the pic16 library,
6431 but now I've commented it out, since gputils aren't installed in the
6432 SF compile farm, so library won't compile
6434 * device/lib/Makefile.in (version 1.56): initially I've added in
6435 target 'all' the prerequestive 'model-pic16' so it compiled the
6436 pic16 library, but now I've commented it out for the same reasons
6438 * added targets 'model-pic16' and 'objects-pic16' to compile the
6440 * added target 'port-specific-objects-pic16' to handle the
6441 generated libraries and copy them into the build/ directory
6442 * added target 'clean-intermediate-pic16' to clean intermediate
6443 files into pic16 directory
6444 * in target 'installdirs' added line to create directory pic16 in
6445 the installation path

6448 added lines to copy all header files to installation path,
6449 * in target 'installdirs' added line create directory for pic16
6450 headers in the installation path

6466 option so that it actually works. Made it specific to the z80, since
6467 the gbz80 doesn't have these kinds of I/O ports.
6469 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6471 * device/include/z180.h,

6578 UPPER for immediate operands,
6579 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6581 * src/pic16/peeph.def: all peepholes with movff are commented out,
6582 because there is a problem in the pcode peep optimizer,
6583 * src/pic16/ralloc.c: the register allocator can now reuse local
6584 function symbols for another function. This saves register usage.
6585 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6587 Added file src/pic16/NOTES with information about program writing on

6693 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6695 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6696 (default behaviour).
6698 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6700 A python script to validate compiler diagnostic messages. It can be
6701 used to verify that sdcc complains about bad c source code and
6702 gives a good location of the error.
6703 * support/valdiag/Makefile,
6704 * support/valdiag/valdiag.py,

6724 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6726 * sdcc.spec: updated
6727 * device/include/Makefile.in: don't install CVS directories
6728 * device/lib/Makefile.in: added removal of CVS directories after install
6729 * doc/Makefile: fixed install, added local_icons
6730 * sim/ucsim/gui.src/Makefile.in: fixed an old typo

6735 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6737 PIC16 port related changes:
6738 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6739 added variable stackPos,
6741 * gen.c: genCall, assignResultValue: added support for
6742 pushing/retrieving function parameters to/from stack,
6743 genFunction,genEndFunction: setup stack frame for the
6745 genAddrOf: will be changed according to bug 863624
6747 * added files genutils.c and genutils.h which contain gen*
6748 debugged and optimised functions extracted from gen.c
6750 * glue.c: added variable 'externs' which holds extern symbols,
6751 pic16emitRegularMap: is modified to properly handle relocatable
6752 symbols under the new scheme,
6753 pic16createInterruptVect: is modified
6754 pic16printPublics: is modified to emit 'global' assembler directives,
6755 added pic16_printExterns to print extern symbols,
6756 pic16glue: initializes stack/frame pointer in the beginning of
6757 the assembly output. Temporary hack, will be corrected later,
6758 because gplink yet does not support stack and SDCC does not
6759 yet support a type of crt0.o object to create the final binary.
6761 * Removed many lines that contain 8051 legacy code.
6762 * The code is finally placed under a 'code' directive.
6763 * Added port specific options.
6765 * _process_pragma: simplified since now we do not need *special*
6766 include file to define SFR registers. But a separate header
6767 will be needed. This will be developed later.
6768 * _pic16_parseOptions: added, parses port specific options:
6769 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6770 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6771 --preplace-udata-with=
6773 * _pic16_setDefaultOptions: modified to initialize section names,
6774 but hack is temporarly out of order since it needs improvement.
6775 * _pic16_genAssemblerPreamble: configuration words are emitted by
6776 their address instead of their name. This part is incomplete and
6777 supports only the 18Fxx2 devices. Other devices will emit an error
6778 during assembly since they do not contain the same set of config
6780 * _pic16_genIVT: is modified,
6782 * pcode.c: added definitions for some hardware registers that are needed
6784 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6785 All PCI entries are updated. Now LFSR is supported.
6786 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6787 * added pic16_newpCodeOpLit2 to support instructions with
6788 two literal arguments
6789 * pic16_pCode2str: corrected code that emits assembler instructions
6790 with two literal operands and those that have an access bit modifier
6791 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6792 this fixes a bug which caused some labels to be lost, when an
6793 assembler directive was added, i.e. banksel,
6794 * pic16_FixRegisterBanking: improved logic that causes the insertion
6796 * InlineFunction: functions that are called once, are not any more
6797 inlined. This can be a port option in the future,
6799 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6801 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6802 hold the corresponding uninitialized symbols,
6803 * pic16_allocProcessorRegister: registers have explicit marked the
6805 * pic16_allocInternalRegister: registers are explicit marked as
6807 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6808 processing list, so bit registers were lost,
6811 * ralloc.h: added field 'accessBank' and original symbol operand
6812 in register definition,
6813 * removed the field isMapped from register definition,
6815 ** Several functions have been removed from various sources:
6816 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6817 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6818 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6819 pic16_assignRelocatableRegisters
6821 ** others have been introduced:
6822 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6823 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6825 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6827 * support/scripts/inc2h.pl: changed definition of BIT_AT
6828 to emit 'sbit at' instead of 'bit at'. This was a request.
6830 PIC16 port related preliminary changes:
6831 * gen.c: prefixed function popRegFromString with
6832 pic16_ and all references to it corrected
6833 * pcode.c: all pic16_pc_* hardware registers prefixed
6834 with underscore (_),
6835 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6836 * ralloc.c: newReg(): when register is REG_SFR then
6837 set address to rIdx,
6838 pic16_allocProcessorRegister(): marks register wasUsed=0
6839 pic16_writeUsedRegs(): added a call to assign processor
6840 registers via pic16_assignFixedRegisters
6842 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6844 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6845 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6846 variables in unused register banks. Also the SSEG is placed
6847 wherever there is enough space for it, and IDATA can be anywhere
6848 in internal RAM. For now compile using -Wl-Y[stack_size].
6849 The mem file is different for this option as well, since it
6850 makes no sense of talking about DSEG lenght.
6852 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6854 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6855 in certain cases, e.g. when ROM assignment, patch provided
6856 from Albert den Haan.
6858 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7744 support for standard C idiom of memory mapped variables; for
7745 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7746 to xdata int at 0x1234 tempvar = 1.
7747 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7748 provided by Akiya ISHIDA

7860 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7861 fetching of the pointer
7862 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7863 copied from genNearPointerSet()
7864 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7865 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

7879 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7881 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7882 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7883 type for bits was changed. It resulted in bit variables becoming
7884 global, which is not permitted in PIC 14 assembly output.
7886 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

7901 A few small changes that speed up the peephole optimizer.
7905 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7907 Try to make the peephole optimizer smarter by maintaining
7908 an association between the assembly source code and the
7909 iCodes that originated them. Put this information to use
7910 with a new peephole rule condition "notVolatile" so that
7911 the rules can be aggressive yet still safe.
7916 * src/mcs51/peeph.def
7918 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7922 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7923 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7924 if the left or right operand symbols have the accuse flag set.
7926 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7928 Changed the type of the result of the ! (NOT) operator to char;
7929 previously it returned the same type as the source. This allows
7930 us to eliminate all the genFloatNot functions (all of its target
7931 implementations were very buggy) since !float can use the same
7934 * src/SDCCicode.c (ast2iCode): ! returns char

7943 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7944 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7945 during interrupts. Ensure WSAVE is located at a shared bank address.
7946 2. Fixed page selection in some places
7947 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7948 the registers name strings.
7949 4. Fixed "signed / unsigned compare" compiler warnings.
7950 5. The PIC port manages its own allocation of the general purpose
7951 registers, but makes no attempt to reuse them. As a result when
7952 compiling it soon runs out of general purpose registers. Some
7953 additional code was added to the files pcode.c and device.c to walk
7954 through the function call tree and rename the registers so that they
7964 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7965 genPlus() & genMinus() when the result is the same as left or right

7971 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7973 Made bitfield a distinct type from bit so that bitfields
7974 convert as per ANSI C and bits retain their traditional
7975 boolean style behaviour. Implemented bitfield support in
7983 * src/ds390/gen.c: bit v bitfield split
7984 * src/z80/gen.c: New support for bitfields
7985 * support/regression/tests/bitfields.c: reenabled z80,
7988 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7990 Rules 246.x, 247.x relate to bitfields, the others speed up
7991 access to xdata mapped I/O devices.
7993 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7995 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7997 Cleaned up genPackBits and genUnpackBits and added two helper
7998 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7999 for literal assignments in genPackBits (thanks to Frieder for
8005 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8007 Fixed bug #748310 (pointer to function type mishandled when the
8008 function name is omitted). Also fixed a SIGSEGV when a function
8009 attribute (reentrant, etc) is used on a non-function or on a
8010 function but misplaced before the parameter list.
8012 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8014 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8015 * support/Util/SDCCerr.h,

8037 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8039 Made the constant following the "interrupt" keyword optional. If
8040 omitted, the function will not automatically be given an entry
8041 in the interrupt vector table (similar to #pragma NOIV, but
8042 less syntacticly kludgy). The interrupt number is also now
8043 range checked. Also fixed a bug in the high order bit example

8057 * src/SDCCicode.c (operandOperation): rewritten some ops
8058 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8059 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8061 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8062 be re-activated by defining REDUCE_LITERALS)

8064 unsigned, but are signed by default

8066 * src/SDCCval.c (valMod): preliminary fix
8067 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8573 added if/endif conditional macros to remove options help
8574 messages from optionsTable when a port is not configured, added
8575 support for the PIc16 port in the ports table, when executing
8576 the compiler with no port specified on command line, a default
8577 port is selected with the new macro DEFAULT_PORT which is
8578 defined in port.h, in setDefaultOptions() linkOptions is removed
8579 from initialization assignment, since now it is a set,
8580 parseCmdLine uses setParseWithComma for linkOptions, in
8581 linkEdit() linkOptions are accessed with new function indexSet()
8582 which returns the i'th item of a set variable. See SDCCset.c, in
8583 linkEdit() when calling buildCmdLine(), added linkOptions as
8584 last argument. Now users can pass arguments to gplink via the
8585 -Wl option, main() uses pic16glue() to glue up pic16 programs

8599 gpasm complaining and test the linkage with gplink, _linkCmd and
8600 _asmCmd changed to be more gplink and gpasm friendly
8601 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8602 produced an error when parsed, peep rule 12 is added to utilize
8603 movff, but it is commented out since the pCode does not support
8604 yet a command with 2 address arguments
8606 2003-05-18 <johan AT balder>
8608 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9647 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9649 2003-01-04 <johan AT balder>
9651 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9653 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9666 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9667 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9669 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9671 * in \sdcc\as\mcs51\ changed these files in order to create an
9672 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9673 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9674 following files to include the previous two files: aslink.dsp,
9675 Makefile.aslink, Makefile.bcc, and Makefile.in.
9677 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9678 .adb instead of .cdb
9680 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9682 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9683 value from option --iram-size.
9685 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9687 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9690 2002-09-18 <wiml AT hhhh.org>
9692 * SDCClrange.h: exposed setFromRange() and setToRange()
9693 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9694 packRegsForAccUse() (bug 542397)
9695 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9696 multiple times and emitting the fetch operations more than once
9697 added aopGetUsesAcc() function to allow binary operators to
9698 fetch their operands in the correct order; made genMinus() emit
9699 compact code for X = LITERAL - Y
9701 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9702 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9703 sprintf() in line 1267.
9705 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9706 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9709 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9710 Changes to aslink (All the changes are marked with 'JCF'):
9712 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9715 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9716 area BSEG. Also moves, if possible, the DATA area down into the internal
9717 ram so more space is available.
9719 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9722 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9723 not bytes. Function summary() which creates a memory usage summary
9724 file with extension .mem. Reports of overlaping stack and small stack
9725 size. If the space for the stack is less than 16 bytes aslink trows a
9728 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9729 the 8051. Option 'y' for memory summary output file.
9731 Changes to sdcc (All the changes are marked with 'JCF'):
9733 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9735 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9736 overlaying area for it (uses RegBankUsed[4]).
9738 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9739 bank zero as used by default. By default aslink locates the stack
9740 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9741 the creation of the .mem file. Delegates the allocation of data area
9742 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9743 the begining of the stack area to aslink.
9745 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9746 glue() in SDCCglue.c creates an area for it.
9748 2002-09-03 Borut Razem <borut.razem AT siol.net>
9749 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9750 sdcc/src/pic/glue.c:
9751 introduced atexit() handler for teporay files removal in case of
9752 errors, assertions, ...
9754 2002-08-29 Borut Razem <borut.razem AT siol.net>
9755 * sdcc/support/cpp2/auto-host_vc_in.h:
9756 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9757 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9758 Maybe there is a similar problem with BORLANDC? It should be checked!
9760 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9761 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9762 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9763 was not executed, and the compiler (cl) launched a warning:
9764 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9766 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9767 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9769 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9770 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9772 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9773 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9774 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9775 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9776 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9777 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9778 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9779 - added Release configuration in VS projects
9780 - review of compiler an linker options
9781 - VC .exe files are generated in bin_vc directory, not to interfere
9782 with binaries generated from other projects (cygwin, mingw, bcc ...)
9784 * sdcc/src/yacc.dsp: added
9786 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9787 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9788 and insert the version number definitions from .version
9790 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9792 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9793 added - genarate auto-host.h using auto-host_vc_in.h as template
9796 removed from CVS, generated automatically
9798 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9799 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9801 2002-08-11 Borut Razem <borut.razem AT siol.net>
9802 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9804 2002-08-10 Borut Razem <borut.razem AT siol.net>
9805 * src/SDCCmain.c (main):
9806 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9807 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9808 The consequence was that some temporary files were not removed.
9811 unification of code in functions tempfilename() and tempfile():
9812 function tempnam() is defined in Visual Studio 6.0 and .NET
9814 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9816 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9817 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9818 - removed compiler command line option /WX: Treats all warnings as errors
9819 - update a list of source files, included into the project
9821 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9822 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9823 changed project type to Generic Project so that can be correcly converted to VS.NET project
9825 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9827 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9829 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9831 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9832 added return 0 statements after assert() to make compiler happy
9834 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9835 added newline in the def file to keep MSC compiler satisfied
9837 * sdcc/src/z80/gen.c:
9838 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9839 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9840 - solved MSC error in function aopDump()
9842 * sdcc_vc.h: define PREFIX as "\\sdcc"
9844 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9845 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9847 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9848 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9849 - Rewrote the register banking algorithm.
9850 - Added pCode live-range analysis to registers (for now, only non-used and
9851 singly-used registers optimized away)
9853 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9855 * 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.

9884 2002-03-28 Johan Knol <johan AT balder>
9886 * src/SDCCval.c: fixed bug #532436
9888 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9890 Added "char *Processor" field to the port structure.
9893 Added -p option. Allows port dependent processor to be specified.
9896 Initialized the new field char *Processor field to NULL in all ports
9899 Compiler generated registers for interrupt context saving
9900 were not getting allocated.
9902 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9905 Fixed left shift. Will promote the left side of a left shift
9906 if a) left shifting more than size of operand or b) when assigned
9907 to something size > size of left side
9909 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9911 tons of changes. Register allocation has been
9912 rewritten. Added customization for the various PICs. Flow
9913 analysis is restructured. ...
9919 Added. device.c is a PIC port hack to accomodate variations
9922 2002-03-13 Michael Hope <michaelh AT vroom>
9924 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9926 2002-03-04 johanknol <johanknol AT manik>
