1303 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1304 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1305 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1306 always available in leading double underscore form. The C99 support is
1307 mostly missing, but it's a start.
1308 * support/regression/tests/bug-227710.c: fixed nonconforming use of
1309 reserved identifier "__data".
1311 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

1353 * src/SDCCBBlock.h (struct ebbIndex): new struct that keeps two copies
1354 of the eBBlock list, sorted by both bbnum and dfnum. (fixes bug with
1355 immedDom() returning wrong block; probably fixes bug #1160833)
1357 2005-03-20 Borut Razem <borut.razem AT siol.net>
1359 * support/scripts/inc2h.pl: WIN32 port
1361 2005-03-19 Maarten Brock <sourceforge.brock AT dse.nl>
1363 * device/lib/makefile.in: added abs.c and labs.c
1365 2005-03-17 Maarten Brock <sourceforge.brock AT dse.nl>
1367 * device/include/stdint.h: added
1368 * device/lib/abs.c: added
1369 * device/lib/labs.c: added
1370 * device/include/stdlib.h: added abs() and labs() prototypes
1371 * device/lib/libsdcc.lib: added abs and labs
1372 * device/include/float.h,

1385 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1387 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1389 * device/lib/printf_large.c: removed inline assembly for portability and
1390 readability. Use printf_fast if speed or size are more important.
1391 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1392 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1394 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1396 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1397 prevent compiler warning
1399 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1401 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1402 moved to level 0 and declared as static. Also they are explicit
1403 placed in access bank. This was necessery because some times they
1404 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1405 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1406 optimizations. Currently only compare to unsigned char is implemented,
1407 * src/pic16/gen.c: added fReturnIdx array,
1408 * (struct resolvedIfx) is moved to gen.h and made public,
1409 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1410 * (aopForSym): added an optimization to directly store in stack of
1411 the operand of a SEND iCode,
1412 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1413 but as registers instead (AOP_REG) using the fReturnIdx array,
1414 * (pic16_freeAsmop): remove the freed register from the
1415 _G.sregsAlloc field,
1416 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1417 a compare of 'WREG',
1418 * (pic16_popGetTempRegCond): changed function prototype, now
1419 function takes also a bitVector argument v which holds the current
1420 set of registers that are allocated for stack access by aopForSym,
1421 registers allocated in aopForSym for accessing stack symbols are not
1422 any more part of the functions usedRegs field,
1423 * (genCall): some times aopOp is called for a stack variable to be
1424 send, aopForSym might perform the push, if this is true make sure
1425 that genCall doesn't push the variable twice by testing _G.resDirect,
1426 * (genFunction): changed testing for unspecified interrupt number
1427 from 256 to INTNO_UNSPEC,
1428 * modified selection scheme of frame pointer generation. Previously
1429 if function did use local registers a frame pointer was generated,
1430 now a frame pointer is generated only if function has arguments
1431 (that need PLUSW2 register access), or has stack arguments, or the
1432 compiler is not instructed to omit the frame pointer,
1433 * (genEndFunction): before restoring local registers that were saved
1434 in the function preamble, also restore the registers that *might*
1435 have been allocated for stack access,
1436 * (genRet): removed some old comments,
1437 * (genCmp, the active (RN's) version): added a call to the
1438 pic16_genCmp_special function to perform the compare with a more
1439 robust and optimized way,
1440 * (genInline): a feature has been added in inline code generation,
1441 which allows a wildcard variable substitution when writing inline
1442 assembly. Code is incomplete and experimental therefore undocumented,
1443 * (genCast): changed order of aopOp for result and right to allow
1444 aopForSym to directly load the result if possible,
1445 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1446 perform an optimized compare on some selected special occasions,
1447 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1448 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1449 generate an IVT any more,
1450 * src/pic16/main.c (pic16_optionsTable): added command line option
1452 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1453 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1455 * src/pic16/NOTES: Raphael Neider added in list of active developers
1456 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1457 jumptable_end to prevent bug #,
1458 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1459 inCond and outCond fields,
1460 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1461 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1462 turn off register spilling,
1463 * (packRegsForOneUse): synced with other ports' versions although it
1464 is not used currently,
1465 * (pic16_packRegisters): added an optimization while reading
1466 structure bitfields, some registers may be saved (malloc code is
1467 decreased by 80 bytes)
1469 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1471 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1472 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1473 this can be optimized more?
1475 2005-03-10 Raphael Neider <rneider AT web.de>
1477 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1478 genNearPointerGet): (hopefully) fixed access to bitfields via
1479 pointers (p->bitN = x; and x = p->bitN; failed)
1481 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1669 (used sizeof(set *sectSyms) instead of sizeof(struct sectSym)),
1670 this might fix SIGSEGVs on MinGW...
1671 * src/SDCCopt.c (killDeadCode): restored original behaviour
1672 (volatile operands might get thrown away though)
1674 2005-01-23 Vangelis Rokas <vrokas AT otenet.gr>

2114 generated for switch statements. For now you need to set the
2115 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2116 Now 4 algorithms for mcs51 jumptable generation are used:
2117 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2118 addresses loaded pc-relative for up to 112 cases and stack-pushing
2119 target addresses loaded with offset from dptr for up to 256 cases.

2149 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2151 * added libc directory. The current version of LibC contains string
2152 functions, ctype functions and macros and some functions of the
2153 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2154 be extensively tested in the future. Standard disclaimer here.
2155 Library is not automatically build yet. But one can build it by
2156 invoking 'make' inside the libc directory.

2166 * (genUminusFloat): fixed for pic16, ported code from mcs51,
2167 * (pic16_storeForReturn): optimized return of 0,
2168 * (genCmp): experimental code for new genCmp which uses PIC18's
2169 special compare&skip instructions. Initial tests fail some times
2170 with variables grater than 1 byte in size, so new code is disabled,
2171 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2173 * (genCast): began a fix to optimize the casting of a bit to another
2174 bit, now assigning a bitfield to another bitfield will fail, sorry,
2175 * src/pic16/main.c: disabled the use of lr-support feature,
2176 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5197 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5199 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5200 loaded with the linker search paths (-L arguments) and the libraries
5201 to be linked with the current source (-l arguments). Changes
5202 currently will affect only the pic16 port.
5203 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5204 include path the port specific paths and port specific libraries,
5205 * gplink command now contains the $3 argument,
5206 * src/pic16/device.h,
5207 * src/pic16/device.c,: structure PIC_device is made public and
5208 renamed to PIC16_device, the same for variable Pics which is renamed

5223 Documenting changes from previous commits.
5224 * configure.in (version 1.56),
5225 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5226 when generating output files to configure the pic16 library,
5227 but now I've commented it out, since gputils aren't installed in the
5228 SF compile farm, so library won't compile
5230 * device/lib/Makefile.in (version 1.56): initially I've added in
5231 target 'all' the prerequestive 'model-pic16' so it compiled the
5232 pic16 library, but now I've commented it out for the same reasons
5234 * added targets 'model-pic16' and 'objects-pic16' to compile the
5236 * added target 'port-specific-objects-pic16' to handle the
5237 generated libraries and copy them into the build/ directory
5238 * added target 'clean-intermediate-pic16' to clean intermediate
5239 files into pic16 directory
5240 * in target 'installdirs' added line to create directory pic16 in
5241 the installation path
5243 * device/include/Makefile.in (version 1.11): in target 'install'
5244 added lines to copy all header files to installation path,
5245 * in target 'installdirs' added line create directory for pic16
5246 headers in the installation path

5262 option so that it actually works. Made it specific to the z80, since
5263 the gbz80 doesn't have these kinds of I/O ports.
5265 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5290 * src/pic16/device.c: stack is allocated via symbol and not
5291 via literal number. The symbol is placed in the corresponding
5292 position of the data ram
5293 * (pic16_dump_section): relocatable and absolute uninitialized
5294 data are now emitted in sorted order to reduce section naming,
5295 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5296 weren't marked as being in the access bank,
5298 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5300 Added portion of GNU PIC Library under the directory
5301 device/include/pic16 and device/lib/pic16. These files
5302 contain the declarations of SFRs for the PIC18Fxx2 devices.
5303 The directory is initialized via configure from toplevel.
5305 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>

5322 in simpler and even better code
5324 2004-01-11 Bernhard Held <bernhard AT bernhardheld.de>
5326 * src/SDCCicode.c (operandOperation): fixed bug #874819

5332 * doc/sdccman.lyx: Moved and added some sections, small changes
5333 all over. Telling LaTeX to be less strict with word spacing
5334 to better keep the right margin. Changed some notes about
5335 maintainance of the ports in section 3.2.1 - is it OK like this?
5337 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5374 UPPER for immediate operands,
5375 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5377 * src/pic16/peeph.def: all peepholes with movff are commented out,
5378 because there is a problem in the pcode peep optimizer,
5379 * src/pic16/ralloc.c: the register allocator can now reuse local
5380 function symbols for another function. This saves register usage.
5381 * src/pic16/ralloc.h: added flag isLocal in structure regs,
5383 Added file src/pic16/NOTES with information about program writing on
5384 the current port version.

5443 * (pic14emitOverlay): modified to emit a commented overlay segment
5444 directive when no overlay data exist
5445 * (picglue): modified to emit uninitialized data segment
5446 according to udata_section_name

5489 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5491 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5492 (default behaviour).
5494 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5496 A python script to validate compiler diagnostic messages. It can be
5497 used to verify that sdcc complains about bad c source code and
5498 gives a good location of the error.
5499 * support/valdiag/Makefile,
5500 * support/valdiag/valdiag.py,
5501 * support/valdiag/tests/*

5518 Bug reported from Jesus Calvino-Fraga
5520 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5522 * sdcc.spec: updated
5523 * device/include/Makefile.in: don't install CVS directories
5524 * device/lib/Makefile.in: added removal of CVS directories after install
5525 * doc/Makefile: fixed install, added local_icons
5526 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5527 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5528 * src/ds390/gen.c (genRightShift): fixed bug #870788
5529 * src/SDCCast.c (decorateType): fixed bug #870781
5531 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5533 PIC16 port related changes:
5534 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5535 added variable stackPos,
5537 * gen.c: genCall, assignResultValue: added support for
5538 pushing/retrieving function parameters to/from stack,
5539 genFunction,genEndFunction: setup stack frame for the
5541 genAddrOf: will be changed according to bug 863624
5543 * added files genutils.c and genutils.h which contain gen*
5544 debugged and optimised functions extracted from gen.c
5546 * glue.c: added variable 'externs' which holds extern symbols,
5547 pic16emitRegularMap: is modified to properly handle relocatable
5548 symbols under the new scheme,
5549 pic16createInterruptVect: is modified
5550 pic16printPublics: is modified to emit 'global' assembler directives,
5551 added pic16_printExterns to print extern symbols,
5552 pic16glue: initializes stack/frame pointer in the beginning of
5553 the assembly output. Temporary hack, will be corrected later,
5554 because gplink yet does not support stack and SDCC does not
5555 yet support a type of crt0.o object to create the final binary.
5557 * Removed many lines that contain 8051 legacy code.
5558 * The code is finally placed under a 'code' directive.
5559 * Added port specific options.
5561 * _process_pragma: simplified since now we do not need *special*
5562 include file to define SFR registers. But a separate header
5563 will be needed. This will be developed later.
5564 * _pic16_parseOptions: added, parses port specific options:
5565 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5566 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5567 --preplace-udata-with=
5569 * _pic16_setDefaultOptions: modified to initialize section names,
5570 but hack is temporarly out of order since it needs improvement.
5571 * _pic16_genAssemblerPreamble: configuration words are emitted by
5572 their address instead of their name. This part is incomplete and
5573 supports only the 18Fxx2 devices. Other devices will emit an error
5574 during assembly since they do not contain the same set of config
5576 * _pic16_genIVT: is modified,
5578 * pcode.c: added definitions for some hardware registers that are needed
5580 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5581 All PCI entries are updated. Now LFSR is supported.
5582 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5583 * added pic16_newpCodeOpLit2 to support instructions with
5584 two literal arguments
5585 * pic16_pCode2str: corrected code that emits assembler instructions
5586 with two literal operands and those that have an access bit modifier
5587 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5588 this fixes a bug which caused some labels to be lost, when an
5589 assembler directive was added, i.e. banksel,
5590 * pic16_FixRegisterBanking: improved logic that causes the insertion
5592 * InlineFunction: functions that are called once, are not any more
5593 inlined. This can be a port option in the future,
5595 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5597 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5598 hold the corresponding uninitialized symbols,
5599 * pic16_allocProcessorRegister: registers have explicit marked the
5601 * pic16_allocInternalRegister: registers are explicit marked as
5603 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5604 processing list, so bit registers were lost,
5607 * ralloc.h: added field 'accessBank' and original symbol operand
5608 in register definition,
5609 * removed the field isMapped from register definition,
5611 ** Several functions have been removed from various sources:
5612 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5613 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5614 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5615 pic16_assignRelocatableRegisters
5617 ** others have been introduced:
5618 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5619 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5621 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5623 * support/scripts/inc2h.pl: changed definition of BIT_AT
5624 to emit 'sbit at' instead of 'bit at'. This was a request.
5626 PIC16 port related preliminary changes:
5627 * gen.c: prefixed function popRegFromString with
5628 pic16_ and all references to it corrected
5629 * pcode.c: all pic16_pc_* hardware registers prefixed
5630 with underscore (_),
5631 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5632 * ralloc.c: newReg(): when register is REG_SFR then
5633 set address to rIdx,
5634 pic16_allocProcessorRegister(): marks register wasUsed=0
5635 pic16_writeUsedRegs(): added a call to assign processor
5636 registers via pic16_assignFixedRegisters
5638 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5640 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5641 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5642 variables in unused register banks. Also the SSEG is placed
5643 wherever there is enough space for it, and IDATA can be anywhere
5644 in internal RAM. For now compile using -Wl-Y[stack_size].
5645 The mem file is different for this option as well, since it
5646 makes no sense of talking about DSEG lenght.
5648 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5650 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5651 in certain cases, e.g. when ROM assignment, patch provided
5652 from Albert den Haan.
5654 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5794 * src/mcs51/main.c: fixed bug #737001 for the mcs51. SDCC clears
5795 xdata and data memory on startup. Set the environment variable
5796 SDCC_NOGENRAMCLEAR to disable this.
5797 * src/mcs51/peephole.def,
5798 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
5799 (allows non-interrupt and interrupt code to safely compete for a resource
5800 without the non-interrupt code having to disable interrupts)
5802 2003-12-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5804 * src/SDCCicode.c (geniCodeAdd),
5805 * src/SDCCast.c (decorateType): fixed bug #857753 (need to be careful
5806 with valFromType if type might be a pointer and host is big endian).

5819 2003-12-12 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5821 * src/mcs51/main.c(_mcs51_genRAMCLEAR): using r0 instead of r1/r2.
5822 Apparently this did not see much testing (endless loop)
5824 2003-12-11 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5826 * src/z80/ralloc.c: set DISABLE_PACK_HL = 1 as a temporary fix to bug #855165
5828 2003-12-10 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5897 it breaks with bitfields, extern declarations, and gcse analysis.
5898 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
5899 could be assigned through a pointer, so don't complain.

6677 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6678 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6679 type for bits was changed. It resulted in bit variables becoming
6680 global, which is not permitted in PIC 14 assembly output.

6697 A few small changes that speed up the peephole optimizer.
6701 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6703 Try to make the peephole optimizer smarter by maintaining
6704 an association between the assembly source code and the
6705 iCodes that originated them. Put this information to use
6706 with a new peephole rule condition "notVolatile" so that
6707 the rules can be aggressive yet still safe.
6712 * src/mcs51/peeph.def
6714 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6718 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6719 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6720 if the left or right operand symbols have the accuse flag set.
6722 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6724 Changed the type of the result of the ! (NOT) operator to char;
6725 previously it returned the same type as the source. This allows
6726 us to eliminate all the genFloatNot functions (all of its target
6727 implementations were very buggy) since !float can use the same
6730 * src/SDCCicode.c (ast2iCode): ! returns char

6739 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6740 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6741 during interrupts. Ensure WSAVE is located at a shared bank address.
6742 2. Fixed page selection in some places
6743 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6744 the registers name strings.
6745 4. Fixed "signed / unsigned compare" compiler warnings.
6746 5. The PIC port manages its own allocation of the general purpose
6747 registers, but makes no attempt to reuse them. As a result when
6748 compiling it soon runs out of general purpose registers. Some
6749 additional code was added to the files pcode.c and device.c to walk
6750 through the function call tree and rename the registers so that they
6760 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6761 genPlus() & genMinus() when the result is the same as left or right

6767 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6769 Made bitfield a distinct type from bit so that bitfields
6770 convert as per ANSI C and bits retain their traditional
6771 boolean style behaviour. Implemented bitfield support in
6779 * src/ds390/gen.c: bit v bitfield split
6780 * src/z80/gen.c: New support for bitfields
6781 * support/regression/tests/bitfields.c: reenabled z80,
6784 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6786 Rules 246.x, 247.x relate to bitfields, the others speed up
6787 access to xdata mapped I/O devices.
6789 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x

6793 Cleaned up genPackBits and genUnpackBits and added two helper
6794 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6795 for literal assignments in genPackBits (thanks to Frieder for
6801 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6803 Fixed bug #748310 (pointer to function type mishandled when the
6804 function name is omitted). Also fixed a SIGSEGV when a function
6805 attribute (reentrant, etc) is used on a non-function or on a
6806 function but misplaced before the parameter list.
6808 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed

6835 Made the constant following the "interrupt" keyword optional. If
6836 omitted, the function will not automatically be given an entry
6837 in the interrupt vector table (similar to #pragma NOIV, but
6838 less syntacticly kludgy). The interrupt number is also now
6839 range checked. Also fixed a bug in the high order bit example

6860 unsigned, but are signed by default
6861 * src/SDCCval.c (constVal): rearranged
6862 * src/SDCCval.c (valMod): preliminary fix
6863 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7367 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
7368 * src/SDCCmain.c: linkOptions is changed to set *,
7369 added if/endif conditional macros to remove options help
7370 messages from optionsTable when a port is not configured, added
7371 support for the PIc16 port in the ports table, when executing
7372 the compiler with no port specified on command line, a default
7373 port is selected with the new macro DEFAULT_PORT which is
7374 defined in port.h, in setDefaultOptions() linkOptions is removed
7375 from initialization assignment, since now it is a set,
7376 parseCmdLine uses setParseWithComma for linkOptions, in
7377 linkEdit() linkOptions are accessed with new function indexSet()
7378 which returns the i'th item of a set variable. See SDCCset.c, in
7379 linkEdit() when calling buildCmdLine(), added linkOptions as
7380 last argument. Now users can pass arguments to gplink via the
7381 -Wl option, main() uses pic16glue() to glue up pic16 programs

7394 * src/pic16/main.c: __config directives are commented out to stop
7395 gpasm complaining and test the linkage with gplink, _linkCmd and
7396 _asmCmd changed to be more gplink and gpasm friendly
7397 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7398 produced an error when parsed, peep rule 12 is added to utilize
7399 movff, but it is commented out since the pCode does not support
7400 yet a command with 2 address arguments

8439 * src/SDCCicode.c: fixed array add
8441 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8442 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8443 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8445 2003-01-04 <johan AT balder>
8447 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8449 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8450 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8452 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
8453 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

8460 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
8462 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8463 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8465 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8467 * in \sdcc\as\mcs51\ changed these files in order to create an
8468 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8469 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8470 following files to include the previous two files: aslink.dsp,
8471 Makefile.aslink, Makefile.bcc, and Makefile.in.
8473 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8474 .adb instead of .cdb
8476 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8478 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8479 value from option --iram-size.
8481 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8483 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8486 2002-09-18 <wiml AT hhhh.org>
8488 * SDCClrange.h: exposed setFromRange() and setToRange()
8489 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8490 packRegsForAccUse() (bug 542397)
8491 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8492 multiple times and emitting the fetch operations more than once
8493 added aopGetUsesAcc() function to allow binary operators to
8494 fetch their operands in the correct order; made genMinus() emit
8495 compact code for X = LITERAL - Y
8497 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8498 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8499 sprintf() in line 1267.
8501 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8502 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8505 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8506 Changes to aslink (All the changes are marked with 'JCF'):
8508 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8511 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8512 area BSEG. Also moves, if possible, the DATA area down into the internal
8513 ram so more space is available.
8515 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8518 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8519 not bytes. Function summary() which creates a memory usage summary
8520 file with extension .mem. Reports of overlaping stack and small stack
8521 size. If the space for the stack is less than 16 bytes aslink trows a
8524 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8525 the 8051. Option 'y' for memory summary output file.
8527 Changes to sdcc (All the changes are marked with 'JCF'):
8529 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8531 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8532 overlaying area for it (uses RegBankUsed[4]).
8534 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8535 bank zero as used by default. By default aslink locates the stack
8536 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8537 the creation of the .mem file. Delegates the allocation of data area
8538 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8539 the begining of the stack area to aslink.
8541 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8542 glue() in SDCCglue.c creates an area for it.
8544 2002-09-03 Borut Razem <borut.razem AT siol.net>
8545 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8546 sdcc/src/pic/glue.c:
8547 introduced atexit() handler for teporay files removal in case of
8548 errors, assertions, ...
8550 2002-08-29 Borut Razem <borut.razem AT siol.net>
8551 * sdcc/support/cpp2/auto-host_vc_in.h:
8552 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8553 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8554 Maybe there is a similar problem with BORLANDC? It should be checked!
8556 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8557 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8558 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8559 was not executed, and the compiler (cl) launched a warning:
8560 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8562 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8563 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8565 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8566 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8568 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8569 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8570 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8571 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8572 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8573 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8574 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8575 - added Release configuration in VS projects
8576 - review of compiler an linker options
8577 - VC .exe files are generated in bin_vc directory, not to interfere
8578 with binaries generated from other projects (cygwin, mingw, bcc ...)
8580 * sdcc/src/yacc.dsp: added
8582 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8583 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8584 and insert the version number definitions from .version
8586 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8588 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8589 added - genarate auto-host.h using auto-host_vc_in.h as template
8592 removed from CVS, generated automatically
8594 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8595 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8597 2002-08-11 Borut Razem <borut.razem AT siol.net>
8598 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8600 2002-08-10 Borut Razem <borut.razem AT siol.net>
8601 * src/SDCCmain.c (main):
8602 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8603 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8604 The consequence was that some temporary files were not removed.
8607 unification of code in functions tempfilename() and tempfile():
8608 function tempnam() is defined in Visual Studio 6.0 and .NET
8610 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8612 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8613 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8614 - removed compiler command line option /WX: Treats all warnings as errors
8615 - update a list of source files, included into the project
8617 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8618 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8619 changed project type to Generic Project so that can be correcly converted to VS.NET project
8621 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8623 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8625 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8627 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8628 added return 0 statements after assert() to make compiler happy
8630 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8631 added newline in the def file to keep MSC compiler satisfied
8633 * sdcc/src/z80/gen.c:
8634 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8635 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8636 - solved MSC error in function aopDump()
8638 * sdcc_vc.h: define PREFIX as "\\sdcc"
8640 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8641 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8643 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8644 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8645 - Rewrote the register banking algorithm.
8646 - Added pCode live-range analysis to registers (for now, only non-used and
8647 singly-used registers optimized away)
8649 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8651 * 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.
8653 2002-05-10 Scott Dattalo <scott AT dattalo.com>
8654 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
8656 2002-04-22 Michael Hope <michaelh AT vroom>
8658 * device/lib/z80/printf.c: Changed emitter to volatile to work around a pcall bug.
8660 * configure.in (DD_COPT): Added include support required for gbdk.
