1312 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1314 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1315 prevent compiler warning
1317 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1319 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1320 moved to level 0 and declared as static. Also they are explicit
1321 placed in access bank. This was necessery because some times they
1322 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1323 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1324 optimizations. Currently only compare to unsigned char is implemented,
1325 * src/pic16/gen.c: added fReturnIdx array,
1326 * (struct resolvedIfx) is moved to gen.h and made public,
1327 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1328 * (aopForSym): added an optimization to directly store in stack of
1329 the operand of a SEND iCode,
1330 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1331 but as registers instead (AOP_REG) using the fReturnIdx array,
1332 * (pic16_freeAsmop): remove the freed register from the
1333 _G.sregsAlloc field,
1334 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1335 a compare of 'WREG',
1336 * (pic16_popGetTempRegCond): changed function prototype, now
1337 function takes also a bitVector argument v which holds the current
1338 set of registers that are allocated for stack access by aopForSym,
1339 registers allocated in aopForSym for accessing stack symbols are not
1340 any more part of the functions usedRegs field,
1341 * (genCall): some times aopOp is called for a stack variable to be
1342 send, aopForSym might perform the push, if this is true make sure
1343 that genCall doesn't push the variable twice by testing _G.resDirect,
1344 * (genFunction): changed testing for unspecified interrupt number
1345 from 256 to INTNO_UNSPEC,
1346 * modified selection scheme of frame pointer generation. Previously
1347 if function did use local registers a frame pointer was generated,
1348 now a frame pointer is generated only if function has arguments
1349 (that need PLUSW2 register access), or has stack arguments, or the
1350 compiler is not instructed to omit the frame pointer,
1351 * (genEndFunction): before restoring local registers that were saved
1352 in the function preamble, also restore the registers that *might*
1353 have been allocated for stack access,
1354 * (genRet): removed some old comments,
1355 * (genCmp, the active (RN's) version): added a call to the
1356 pic16_genCmp_special function to perform the compare with a more
1357 robust and optimized way,
1358 * (genInline): a feature has been added in inline code generation,
1359 which allows a wildcard variable substitution when writing inline
1360 assembly. Code is incomplete and experimental therefore undocumented,
1361 * (genCast): changed order of aopOp for result and right to allow
1362 aopForSym to directly load the result if possible,
1363 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1364 perform an optimized compare on some selected special occasions,
1365 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1366 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1367 generate an IVT any more,
1368 * src/pic16/main.c (pic16_optionsTable): added command line option
1370 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1371 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1373 * src/pic16/NOTES: Raphael Neider added in list of active developers
1374 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1375 jumptable_end to prevent bug #,
1376 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1377 inCond and outCond fields,
1378 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1379 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1380 turn off register spilling,
1381 * (packRegsForOneUse): synced with other ports' versions although it
1382 is not used currently,
1383 * (pic16_packRegisters): added an optimization while reading
1384 structure bitfields, some registers may be saved (malloc code is
1385 decreased by 80 bytes)
1387 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1389 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1390 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1391 this can be optimized more?
1393 2005-03-10 Raphael Neider <rneider AT web.de>
1395 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1396 genNearPointerGet): (hopefully) fixed access to bitfields via
1397 pointers (p->bitN = x; and x = p->bitN; failed)

1723 access stack and frame pointers. They are initially assigned to
1724 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
1725 accessing SFRs. Updated all occurences of modification of stack or
1726 frame pointer in gen.c and pcode.c,
1727 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
1728 assigning of a literal value to pointers,

1763 * src/pic16/pcode.c (pic16_OptimizeJumps): removed annoying statistics
1765 * (pic16_newpCodeOpLit): changed to cast to unsigned char (as e.g. -32766
1766 is an invalid literal too...)

2069 * added libc directory. The current version of LibC contains string
2070 functions, ctype functions and macros and some functions of the
2071 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2072 be extensively tested in the future. Standard disclaimer here.
2073 Library is not automatically build yet. But one can build it by

2086 * (genCmp): experimental code for new genCmp which uses PIC18's
2087 special compare&skip instructions. Initial tests fail some times
2088 with variables grater than 1 byte in size, so new code is disabled,
2089 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2091 * (genCast): began a fix to optimize the casting of a bit to another
2092 bit, now assigning a bitfield to another bitfield will fail, sorry,

2106 registers when it shouldn't,
2107 * src/pic16/ralloc.c (allocReg): add preliminary support for
2108 supporting a limited set of temporary registers,

5117 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5118 loaded with the linker search paths (-L arguments) and the libraries
5119 to be linked with the current source (-l arguments). Changes
5120 currently will affect only the pic16 port.
5121 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5122 include path the port specific paths and port specific libraries,
5123 * gplink command now contains the $3 argument,
5124 * src/pic16/device.h,
5125 * src/pic16/device.c,: structure PIC_device is made public and

5141 Documenting changes from previous commits.
5142 * configure.in (version 1.56),
5143 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5144 when generating output files to configure the pic16 library,
5145 but now I've commented it out, since gputils aren't installed in the
5146 SF compile farm, so library won't compile
5148 * device/lib/Makefile.in (version 1.56): initially I've added in
5149 target 'all' the prerequestive 'model-pic16' so it compiled the
5150 pic16 library, but now I've commented it out for the same reasons
5152 * added targets 'model-pic16' and 'objects-pic16' to compile the
5154 * added target 'port-specific-objects-pic16' to handle the
5155 generated libraries and copy them into the build/ directory
5156 * added target 'clean-intermediate-pic16' to clean intermediate
5157 files into pic16 directory
5158 * in target 'installdirs' added line to create directory pic16 in

5180 option so that it actually works. Made it specific to the z80, since
5181 the gbz80 doesn't have these kinds of I/O ports.
5183 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5185 * device/include/z180.h,

5209 via literal number. The symbol is placed in the corresponding
5210 position of the data ram
5211 * (pic16_dump_section): relocatable and absolute uninitialized
5212 data are now emitted in sorted order to reduce section naming,
5213 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5214 weren't marked as being in the access bank,
5216 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5218 Added portion of GNU PIC Library under the directory

5293 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5295 * src/pic16/peeph.def: all peepholes with movff are commented out,
5296 because there is a problem in the pcode peep optimizer,
5297 * src/pic16/ralloc.c: the register allocator can now reuse local
5298 function symbols for another function. This saves register usage.

5390 include information about variables allocated to the overlay
5393 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5395 * as/mcs51/lkmain.c: Help about -Y option

5405 LEFT_OP (left shift)
5407 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5409 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5410 (default behaviour).
5412 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5414 A python script to validate compiler diagnostic messages. It can be
5415 used to verify that sdcc complains about bad c source code and
5416 gives a good location of the error.
5417 * support/valdiag/Makefile,
5418 * support/valdiag/valdiag.py,
5419 * support/valdiag/tests/*

5436 Bug reported from Jesus Calvino-Fraga
5438 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5440 * sdcc.spec: updated
5441 * device/include/Makefile.in: don't install CVS directories
5442 * device/lib/Makefile.in: added removal of CVS directories after install
5443 * doc/Makefile: fixed install, added local_icons
5444 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5445 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5446 * src/ds390/gen.c (genRightShift): fixed bug #870788

5449 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5451 PIC16 port related changes:
5452 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5453 added variable stackPos,
5455 * gen.c: genCall, assignResultValue: added support for
5456 pushing/retrieving function parameters to/from stack,
5457 genFunction,genEndFunction: setup stack frame for the
5459 genAddrOf: will be changed according to bug 863624
5461 * added files genutils.c and genutils.h which contain gen*
5462 debugged and optimised functions extracted from gen.c
5464 * glue.c: added variable 'externs' which holds extern symbols,
5465 pic16emitRegularMap: is modified to properly handle relocatable
5466 symbols under the new scheme,
5467 pic16createInterruptVect: is modified
5468 pic16printPublics: is modified to emit 'global' assembler directives,
5469 added pic16_printExterns to print extern symbols,
5470 pic16glue: initializes stack/frame pointer in the beginning of
5471 the assembly output. Temporary hack, will be corrected later,
5472 because gplink yet does not support stack and SDCC does not
5473 yet support a type of crt0.o object to create the final binary.
5475 * Removed many lines that contain 8051 legacy code.
5476 * The code is finally placed under a 'code' directive.
5477 * Added port specific options.
5479 * _process_pragma: simplified since now we do not need *special*
5480 include file to define SFR registers. But a separate header
5481 will be needed. This will be developed later.
5482 * _pic16_parseOptions: added, parses port specific options:
5483 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5484 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5485 --preplace-udata-with=
5487 * _pic16_setDefaultOptions: modified to initialize section names,
5488 but hack is temporarly out of order since it needs improvement.
5489 * _pic16_genAssemblerPreamble: configuration words are emitted by
5490 their address instead of their name. This part is incomplete and
5491 supports only the 18Fxx2 devices. Other devices will emit an error
5492 during assembly since they do not contain the same set of config
5494 * _pic16_genIVT: is modified,
5496 * pcode.c: added definitions for some hardware registers that are needed
5498 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5499 All PCI entries are updated. Now LFSR is supported.
5500 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5501 * added pic16_newpCodeOpLit2 to support instructions with
5502 two literal arguments
5503 * pic16_pCode2str: corrected code that emits assembler instructions
5504 with two literal operands and those that have an access bit modifier
5505 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5506 this fixes a bug which caused some labels to be lost, when an
5507 assembler directive was added, i.e. banksel,
5508 * pic16_FixRegisterBanking: improved logic that causes the insertion
5510 * InlineFunction: functions that are called once, are not any more
5511 inlined. This can be a port option in the future,
5513 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5515 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5516 hold the corresponding uninitialized symbols,
5517 * pic16_allocProcessorRegister: registers have explicit marked the
5519 * pic16_allocInternalRegister: registers are explicit marked as
5521 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5522 processing list, so bit registers were lost,
5525 * ralloc.h: added field 'accessBank' and original symbol operand
5526 in register definition,
5527 * removed the field isMapped from register definition,
5529 ** Several functions have been removed from various sources:
5530 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5531 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5532 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5533 pic16_assignRelocatableRegisters
5535 ** others have been introduced:
5536 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5537 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5539 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5541 * support/scripts/inc2h.pl: changed definition of BIT_AT
5542 to emit 'sbit at' instead of 'bit at'. This was a request.
5544 PIC16 port related preliminary changes:
5545 * gen.c: prefixed function popRegFromString with
5546 pic16_ and all references to it corrected
5547 * pcode.c: all pic16_pc_* hardware registers prefixed
5548 with underscore (_),
5549 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5550 * ralloc.c: newReg(): when register is REG_SFR then
5551 set address to rIdx,
5552 pic16_allocProcessorRegister(): marks register wasUsed=0
5553 pic16_writeUsedRegs(): added a call to assign processor
5554 registers via pic16_assignFixedRegisters
5556 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5558 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5559 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5560 variables in unused register banks. Also the SSEG is placed
5561 wherever there is enough space for it, and IDATA can be anywhere
5562 in internal RAM. For now compile using -Wl-Y[stack_size].
5563 The mem file is different for this option as well, since it
5564 makes no sense of talking about DSEG lenght.
5566 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5568 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5569 in certain cases, e.g. when ROM assignment, patch provided
5570 from Albert den Haan.
5572 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6457 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
6458 support for standard C idiom of memory mapped variables; for
6459 example, *((xdata int*)0x1234) = 1 is now internally equivalent
6460 to xdata int at 0x1234 tempvar = 1.
6461 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
6462 provided by Akiya ISHIDA

6478 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6480 Fixed bug #621531 (const & volatile confusion in the type chain).
6481 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

6573 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
6574 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6575 fetching of the pointer
6576 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6577 copied from genNearPointerSet()
6578 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6579 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
6580 If they pop r0/r1 they must be called in the opposite order than aopOp().
6581 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"

6593 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6595 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6596 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6597 type for bits was changed. It resulted in bit variables becoming
6598 global, which is not permitted in PIC 14 assembly output.
6600 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6602 * doc/sdccman.lyx: various additions and updates. Rearranged sections

6615 A few small changes that speed up the peephole optimizer.
6619 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6621 Try to make the peephole optimizer smarter by maintaining
6622 an association between the assembly source code and the
6623 iCodes that originated them. Put this information to use
6624 with a new peephole rule condition "notVolatile" so that
6625 the rules can be aggressive yet still safe.
6630 * src/mcs51/peeph.def
6632 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6636 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6637 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6638 if the left or right operand symbols have the accuse flag set.
6640 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6642 Changed the type of the result of the ! (NOT) operator to char;
6643 previously it returned the same type as the source. This allows
6644 us to eliminate all the genFloatNot functions (all of its target
6645 implementations were very buggy) since !float can use the same
6648 * src/SDCCicode.c (ast2iCode): ! returns char

6655 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
6657 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6658 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6659 during interrupts. Ensure WSAVE is located at a shared bank address.
6660 2. Fixed page selection in some places
6661 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6662 the registers name strings.
6663 4. Fixed "signed / unsigned compare" compiler warnings.
6664 5. The PIC port manages its own allocation of the general purpose
6665 registers, but makes no attempt to reuse them. As a result when
6666 compiling it soon runs out of general purpose registers. Some
6667 additional code was added to the files pcode.c and device.c to walk
6668 through the function call tree and rename the registers so that they
6678 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
6679 genPlus() & genMinus() when the result is the same as left or right
6681 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6685 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6687 Made bitfield a distinct type from bit so that bitfields
6688 convert as per ANSI C and bits retain their traditional
6689 boolean style behaviour. Implemented bitfield support in
6697 * src/ds390/gen.c: bit v bitfield split
6698 * src/z80/gen.c: New support for bitfields
6699 * support/regression/tests/bitfields.c: reenabled z80,
6702 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6704 Rules 246.x, 247.x relate to bitfields, the others speed up
6705 access to xdata mapped I/O devices.
6707 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6709 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6711 Cleaned up genPackBits and genUnpackBits and added two helper
6712 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6713 for literal assignments in genPackBits (thanks to Frieder for
6719 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6721 Fixed bug #748310 (pointer to function type mishandled when the
6722 function name is omitted). Also fixed a SIGSEGV when a function
6723 attribute (reentrant, etc) is used on a non-function or on a
6724 function but misplaced before the parameter list.
6726 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6728 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6729 * support/Util/SDCCerr.h,
6730 * support/Util/SDCCerr.c: Added func attr misuse error msg

6751 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6753 Made the constant following the "interrupt" keyword optional. If
6754 omitted, the function will not automatically be given an entry
6755 in the interrupt vector table (similar to #pragma NOIV, but
6756 less syntacticly kludgy). The interrupt number is also now
6757 range checked. Also fixed a bug in the high order bit example

6771 * src/SDCCicode.c (operandOperation): rewritten some ops
6772 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6773 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6775 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
6776 be re-activated by defining REDUCE_LITERALS)
6777 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
6778 unsigned, but are signed by default
6779 * src/SDCCval.c (constVal): rearranged
6780 * src/SDCCval.c (valMod): preliminary fix
6781 * src/SDCCval.c (valCastLiteral): use TYPE_* types

7287 added if/endif conditional macros to remove options help
7288 messages from optionsTable when a port is not configured, added
7289 support for the PIc16 port in the ports table, when executing
7290 the compiler with no port specified on command line, a default
7291 port is selected with the new macro DEFAULT_PORT which is
7292 defined in port.h, in setDefaultOptions() linkOptions is removed
7293 from initialization assignment, since now it is a set,
7294 parseCmdLine uses setParseWithComma for linkOptions, in
7295 linkEdit() linkOptions are accessed with new function indexSet()
7296 which returns the i'th item of a set variable. See SDCCset.c, in
7297 linkEdit() when calling buildCmdLine(), added linkOptions as
7298 last argument. Now users can pass arguments to gplink via the
7299 -Wl option, main() uses pic16glue() to glue up pic16 programs

7313 gpasm complaining and test the linkage with gplink, _linkCmd and
7314 _asmCmd changed to be more gplink and gpasm friendly
7315 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7316 produced an error when parsed, peep rule 12 is added to utilize
7317 movff, but it is commented out since the pCode does not support
7318 yet a command with 2 address arguments
7320 2003-05-18 <johan AT balder>
7322 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7345 2003-05-12 Borut Razem <borut.razem AT siol.net>
7347 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
7349 2003-05-11 Borut Razem <borut.razem AT siol.net>
7351 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7352 the path of bin directory, so that PATH is the only env. variable, which has to be set
7353 in case of standard installation.

8357 * src/SDCCicode.c: fixed array add
8359 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8360 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8361 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8363 2003-01-04 <johan AT balder>
8365 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8367 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8368 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8370 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

8380 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8381 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8383 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8385 * in \sdcc\as\mcs51\ changed these files in order to create an
8386 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8387 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8388 following files to include the previous two files: aslink.dsp,
8389 Makefile.aslink, Makefile.bcc, and Makefile.in.
8391 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8392 .adb instead of .cdb
8394 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8396 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8397 value from option --iram-size.
8399 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8401 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8404 2002-09-18 <wiml AT hhhh.org>
8406 * SDCClrange.h: exposed setFromRange() and setToRange()
8407 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8408 packRegsForAccUse() (bug 542397)
8409 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8410 multiple times and emitting the fetch operations more than once
8411 added aopGetUsesAcc() function to allow binary operators to
8412 fetch their operands in the correct order; made genMinus() emit
8413 compact code for X = LITERAL - Y
8415 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8416 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8417 sprintf() in line 1267.
8419 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8420 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8423 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8424 Changes to aslink (All the changes are marked with 'JCF'):
8426 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8429 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8430 area BSEG. Also moves, if possible, the DATA area down into the internal
8431 ram so more space is available.
8433 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8436 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8437 not bytes. Function summary() which creates a memory usage summary
8438 file with extension .mem. Reports of overlaping stack and small stack
8439 size. If the space for the stack is less than 16 bytes aslink trows a
8442 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8443 the 8051. Option 'y' for memory summary output file.
8445 Changes to sdcc (All the changes are marked with 'JCF'):
8447 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8449 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8450 overlaying area for it (uses RegBankUsed[4]).
8452 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8453 bank zero as used by default. By default aslink locates the stack
8454 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8455 the creation of the .mem file. Delegates the allocation of data area
8456 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8457 the begining of the stack area to aslink.
8459 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8460 glue() in SDCCglue.c creates an area for it.
8462 2002-09-03 Borut Razem <borut.razem AT siol.net>
8463 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8464 sdcc/src/pic/glue.c:
8465 introduced atexit() handler for teporay files removal in case of
8466 errors, assertions, ...
8468 2002-08-29 Borut Razem <borut.razem AT siol.net>
8469 * sdcc/support/cpp2/auto-host_vc_in.h:
8470 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8471 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8472 Maybe there is a similar problem with BORLANDC? It should be checked!
8474 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8475 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8476 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8477 was not executed, and the compiler (cl) launched a warning:
8478 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8480 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8481 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8483 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8484 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8486 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8487 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8488 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8489 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8490 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8491 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8492 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8493 - added Release configuration in VS projects
8494 - review of compiler an linker options
8495 - VC .exe files are generated in bin_vc directory, not to interfere
8496 with binaries generated from other projects (cygwin, mingw, bcc ...)
8498 * sdcc/src/yacc.dsp: added
8500 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8501 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8502 and insert the version number definitions from .version
8504 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8506 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8507 added - genarate auto-host.h using auto-host_vc_in.h as template
8510 removed from CVS, generated automatically
8512 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8513 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8515 2002-08-11 Borut Razem <borut.razem AT siol.net>
8516 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8518 2002-08-10 Borut Razem <borut.razem AT siol.net>
8519 * src/SDCCmain.c (main):
8520 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8521 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8522 The consequence was that some temporary files were not removed.
8525 unification of code in functions tempfilename() and tempfile():
8526 function tempnam() is defined in Visual Studio 6.0 and .NET
8528 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8530 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8531 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8532 - removed compiler command line option /WX: Treats all warnings as errors
8533 - update a list of source files, included into the project
8535 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8536 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8537 changed project type to Generic Project so that can be correcly converted to VS.NET project
8539 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8541 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8543 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8545 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8546 added return 0 statements after assert() to make compiler happy
8548 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8549 added newline in the def file to keep MSC compiler satisfied
8551 * sdcc/src/z80/gen.c:
8552 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8553 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8554 - solved MSC error in function aopDump()
8556 * sdcc_vc.h: define PREFIX as "\\sdcc"
8558 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8559 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8562 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8563 - Rewrote the register banking algorithm.
8564 - Added pCode live-range analysis to registers (for now, only non-used and
8565 singly-used registers optimized away)
8567 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8569 * 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.

8598 2002-03-28 Johan Knol <johan AT balder>
8600 * src/SDCCval.c: fixed bug #532436
8602 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8604 Added "char *Processor" field to the port structure.
8607 Added -p option. Allows port dependent processor to be specified.
8610 Initialized the new field char *Processor field to NULL in all ports
8613 Compiler generated registers for interrupt context saving
8614 were not getting allocated.
8616 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8619 Fixed left shift. Will promote the left side of a left shift
8620 if a) left shifting more than size of operand or b) when assigned
8621 to something size > size of left side
8623 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8625 tons of changes. Register allocation has been
8626 rewritten. Added customization for the various PICs. Flow
8627 analysis is restructured. ...
8633 Added. device.c is a PIC port hack to accomodate variations

8733 * sdcc/src/SDCCloop.c:
8734 Previous fix was not good. basic blocks that have "break" or "return" are
8735 not really partof a loop , but live ranges used in these blocks should
8736 be live thru the entire loop, so set partOfLoop but don't add them to
