1311 * device/lib/_fsmul.c,
1312 * device/lib/printf_fast.c,
1313 * device/lib/printf_tiny.c: updated comments
1315 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1317 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
1320 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1322 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
1323 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
1325 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1327 * device/lib/printf_large.c: removed inline assembly for portability and
1328 readability. Use printf_fast if speed or size are more important.
1329 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1330 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1332 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1334 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1335 prevent compiler warning
1337 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1339 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1340 moved to level 0 and declared as static. Also they are explicit
1341 placed in access bank. This was necessery because some times they
1342 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1343 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1344 optimizations. Currently only compare to unsigned char is implemented,
1345 * src/pic16/gen.c: added fReturnIdx array,
1346 * (struct resolvedIfx) is moved to gen.h and made public,
1347 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1348 * (aopForSym): added an optimization to directly store in stack of
1349 the operand of a SEND iCode,
1350 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1351 but as registers instead (AOP_REG) using the fReturnIdx array,
1352 * (pic16_freeAsmop): remove the freed register from the
1353 _G.sregsAlloc field,
1354 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1355 a compare of 'WREG',
1356 * (pic16_popGetTempRegCond): changed function prototype, now
1357 function takes also a bitVector argument v which holds the current
1358 set of registers that are allocated for stack access by aopForSym,
1359 registers allocated in aopForSym for accessing stack symbols are not
1360 any more part of the functions usedRegs field,
1361 * (genCall): some times aopOp is called for a stack variable to be
1362 send, aopForSym might perform the push, if this is true make sure
1363 that genCall doesn't push the variable twice by testing _G.resDirect,
1364 * (genFunction): changed testing for unspecified interrupt number
1365 from 256 to INTNO_UNSPEC,
1366 * modified selection scheme of frame pointer generation. Previously
1367 if function did use local registers a frame pointer was generated,
1368 now a frame pointer is generated only if function has arguments
1369 (that need PLUSW2 register access), or has stack arguments, or the
1370 compiler is not instructed to omit the frame pointer,
1371 * (genEndFunction): before restoring local registers that were saved
1372 in the function preamble, also restore the registers that *might*
1373 have been allocated for stack access,
1374 * (genRet): removed some old comments,
1375 * (genCmp, the active (RN's) version): added a call to the
1376 pic16_genCmp_special function to perform the compare with a more
1377 robust and optimized way,
1378 * (genInline): a feature has been added in inline code generation,
1379 which allows a wildcard variable substitution when writing inline
1380 assembly. Code is incomplete and experimental therefore undocumented,
1381 * (genCast): changed order of aopOp for result and right to allow
1382 aopForSym to directly load the result if possible,
1383 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1384 perform an optimized compare on some selected special occasions,
1385 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1386 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1387 generate an IVT any more,
1388 * src/pic16/main.c (pic16_optionsTable): added command line option
1390 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1391 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1393 * src/pic16/NOTES: Raphael Neider added in list of active developers
1394 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1395 jumptable_end to prevent bug #,
1396 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1397 inCond and outCond fields,
1398 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1399 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1400 turn off register spilling,
1401 * (packRegsForOneUse): synced with other ports' versions although it
1402 is not used currently,
1403 * (pic16_packRegisters): added an optimization while reading
1404 structure bitfields, some registers may be saved (malloc code is
1405 decreased by 80 bytes)
1407 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1409 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1410 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1411 this can be optimized more?
1413 2005-03-10 Raphael Neider <rneider AT web.de>
1415 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1416 genNearPointerGet): (hopefully) fixed access to bitfields via
1417 pointers (p->bitN = x; and x = p->bitN; failed)
1419 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1462 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1463 to keep the correct label reference count when adding/removing references
1464 to labels. A peephole file using this is appended to patch #1144962.

1743 access stack and frame pointers. They are initially assigned to
1744 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
1745 accessing SFRs. Updated all occurences of modification of stack or

2089 * added libc directory. The current version of LibC contains string
2090 functions, ctype functions and macros and some functions of the
2091 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2092 be extensively tested in the future. Standard disclaimer here.

2107 special compare&skip instructions. Initial tests fail some times
2108 with variables grater than 1 byte in size, so new code is disabled,
2109 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2111 * (genCast): began a fix to optimize the casting of a bit to another
2112 bit, now assigning a bitfield to another bitfield will fail, sorry,

2127 * src/pic16/ralloc.c (allocReg): add preliminary support for
2128 supporting a limited set of temporary registers,
2130 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5137 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5138 loaded with the linker search paths (-L arguments) and the libraries
5139 to be linked with the current source (-l arguments). Changes
5140 currently will affect only the pic16 port.
5141 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5142 include path the port specific paths and port specific libraries,
5143 * gplink command now contains the $3 argument,
5144 * src/pic16/device.h,
5145 * src/pic16/device.c,: structure PIC_device is made public and

5161 Documenting changes from previous commits.
5162 * configure.in (version 1.56),
5163 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5164 when generating output files to configure the pic16 library,
5165 but now I've commented it out, since gputils aren't installed in the
5166 SF compile farm, so library won't compile
5168 * device/lib/Makefile.in (version 1.56): initially I've added in
5169 target 'all' the prerequestive 'model-pic16' so it compiled the
5170 pic16 library, but now I've commented it out for the same reasons
5172 * added targets 'model-pic16' and 'objects-pic16' to compile the
5174 * added target 'port-specific-objects-pic16' to handle the
5175 generated libraries and copy them into the build/ directory
5176 * added target 'clean-intermediate-pic16' to clean intermediate
5177 files into pic16 directory
5178 * in target 'installdirs' added line to create directory pic16 in

5182 added lines to copy all header files to installation path,
5183 * in target 'installdirs' added line create directory for pic16
5184 headers in the installation path

5200 option so that it actually works. Made it specific to the z80, since
5201 the gbz80 doesn't have these kinds of I/O ports.
5203 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5205 * device/include/z180.h,

5229 via literal number. The symbol is placed in the corresponding
5230 position of the data ram
5231 * (pic16_dump_section): relocatable and absolute uninitialized
5232 data are now emitted in sorted order to reduce section naming,
5233 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5234 weren't marked as being in the access bank,
5236 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5238 Added portion of GNU PIC Library under the directory
5239 device/include/pic16 and device/lib/pic16. These files
5240 contain the declarations of SFRs for the PIC18Fxx2 devices.
5241 The directory is initialized via configure from toplevel.

5271 all over. Telling LaTeX to be less strict with word spacing
5272 to better keep the right margin. Changed some notes about
5273 maintainance of the ports in section 3.2.1 - is it OK like this?
5275 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

5311 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
5312 UPPER for immediate operands,
5313 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
5315 * src/pic16/peeph.def: all peepholes with movff are commented out,
5316 because there is a problem in the pcode peep optimizer,
5317 * src/pic16/ralloc.c: the register allocator can now reuse local
5318 function symbols for another function. This saves register usage.

5427 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5429 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
5430 (default behaviour).
5432 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5434 A python script to validate compiler diagnostic messages. It can be
5435 used to verify that sdcc complains about bad c source code and
5436 gives a good location of the error.
5437 * support/valdiag/Makefile,
5438 * support/valdiag/valdiag.py,
5439 * support/valdiag/tests/*

5456 Bug reported from Jesus Calvino-Fraga
5458 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
5460 * sdcc.spec: updated
5461 * device/include/Makefile.in: don't install CVS directories
5462 * device/lib/Makefile.in: added removal of CVS directories after install
5463 * doc/Makefile: fixed install, added local_icons
5464 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
5465 * src/mcs51/gen.c (genRightShift): fixed bug #870788
5466 * src/ds390/gen.c (genRightShift): fixed bug #870788

5469 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
5471 PIC16 port related changes:
5472 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
5473 added variable stackPos,
5475 * gen.c: genCall, assignResultValue: added support for
5476 pushing/retrieving function parameters to/from stack,
5477 genFunction,genEndFunction: setup stack frame for the
5479 genAddrOf: will be changed according to bug 863624
5481 * added files genutils.c and genutils.h which contain gen*
5482 debugged and optimised functions extracted from gen.c
5484 * glue.c: added variable 'externs' which holds extern symbols,
5485 pic16emitRegularMap: is modified to properly handle relocatable
5486 symbols under the new scheme,
5487 pic16createInterruptVect: is modified
5488 pic16printPublics: is modified to emit 'global' assembler directives,
5489 added pic16_printExterns to print extern symbols,
5490 pic16glue: initializes stack/frame pointer in the beginning of
5491 the assembly output. Temporary hack, will be corrected later,
5492 because gplink yet does not support stack and SDCC does not
5493 yet support a type of crt0.o object to create the final binary.
5495 * Removed many lines that contain 8051 legacy code.
5496 * The code is finally placed under a 'code' directive.
5497 * Added port specific options.
5499 * _process_pragma: simplified since now we do not need *special*
5500 include file to define SFR registers. But a separate header
5501 will be needed. This will be developed later.
5502 * _pic16_parseOptions: added, parses port specific options:
5503 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5504 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5505 --preplace-udata-with=
5507 * _pic16_setDefaultOptions: modified to initialize section names,
5508 but hack is temporarly out of order since it needs improvement.
5509 * _pic16_genAssemblerPreamble: configuration words are emitted by
5510 their address instead of their name. This part is incomplete and
5511 supports only the 18Fxx2 devices. Other devices will emit an error
5512 during assembly since they do not contain the same set of config
5514 * _pic16_genIVT: is modified,
5516 * pcode.c: added definitions for some hardware registers that are needed
5518 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5519 All PCI entries are updated. Now LFSR is supported.
5520 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5521 * added pic16_newpCodeOpLit2 to support instructions with
5522 two literal arguments
5523 * pic16_pCode2str: corrected code that emits assembler instructions
5524 with two literal operands and those that have an access bit modifier
5525 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5526 this fixes a bug which caused some labels to be lost, when an
5527 assembler directive was added, i.e. banksel,
5528 * pic16_FixRegisterBanking: improved logic that causes the insertion
5530 * InlineFunction: functions that are called once, are not any more
5531 inlined. This can be a port option in the future,
5533 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5535 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5536 hold the corresponding uninitialized symbols,
5537 * pic16_allocProcessorRegister: registers have explicit marked the
5539 * pic16_allocInternalRegister: registers are explicit marked as
5541 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5542 processing list, so bit registers were lost,
5545 * ralloc.h: added field 'accessBank' and original symbol operand
5546 in register definition,
5547 * removed the field isMapped from register definition,
5549 ** Several functions have been removed from various sources:
5550 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5551 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5552 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5553 pic16_assignRelocatableRegisters
5555 ** others have been introduced:
5556 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5557 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5559 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5561 * support/scripts/inc2h.pl: changed definition of BIT_AT
5562 to emit 'sbit at' instead of 'bit at'. This was a request.
5564 PIC16 port related preliminary changes:
5565 * gen.c: prefixed function popRegFromString with
5566 pic16_ and all references to it corrected
5567 * pcode.c: all pic16_pc_* hardware registers prefixed
5568 with underscore (_),
5569 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5570 * ralloc.c: newReg(): when register is REG_SFR then
5571 set address to rIdx,
5572 pic16_allocProcessorRegister(): marks register wasUsed=0
5573 pic16_writeUsedRegs(): added a call to assign processor
5574 registers via pic16_assignFixedRegisters
5576 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5578 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5579 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5580 variables in unused register banks. Also the SSEG is placed
5581 wherever there is enough space for it, and IDATA can be anywhere
5582 in internal RAM. For now compile using -Wl-Y[stack_size].
5583 The mem file is different for this option as well, since it
5584 makes no sense of talking about DSEG lenght.
5586 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5588 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5589 in certain cases, e.g. when ROM assignment, patch provided
5590 from Albert den Haan.
5592 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

5735 * src/mcs51/peephole.def,
5736 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
5737 (allows non-interrupt and interrupt code to safely compete for a resource

6594 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6595 fetching of the pointer
6596 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6597 copied from genNearPointerSet()
6598 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6599 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
6600 If they pop r0/r1 they must be called in the opposite order than aopOp().

6613 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
6615 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6616 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6617 type for bits was changed. It resulted in bit variables becoming
6618 global, which is not permitted in PIC 14 assembly output.
6620 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

6635 A few small changes that speed up the peephole optimizer.
6639 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6641 Try to make the peephole optimizer smarter by maintaining
6642 an association between the assembly source code and the
6643 iCodes that originated them. Put this information to use
6644 with a new peephole rule condition "notVolatile" so that
6645 the rules can be aggressive yet still safe.
6650 * src/mcs51/peeph.def
6652 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6656 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6657 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6658 if the left or right operand symbols have the accuse flag set.
6660 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6662 Changed the type of the result of the ! (NOT) operator to char;
6663 previously it returned the same type as the source. This allows
6664 us to eliminate all the genFloatNot functions (all of its target
6665 implementations were very buggy) since !float can use the same

6677 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6678 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6679 during interrupts. Ensure WSAVE is located at a shared bank address.
6680 2. Fixed page selection in some places
6681 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6682 the registers name strings.
6683 4. Fixed "signed / unsigned compare" compiler warnings.
6684 5. The PIC port manages its own allocation of the general purpose
6685 registers, but makes no attempt to reuse them. As a result when
6686 compiling it soon runs out of general purpose registers. Some
6687 additional code was added to the files pcode.c and device.c to walk
6688 through the function call tree and rename the registers so that they
6698 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6705 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6707 Made bitfield a distinct type from bit so that bitfields
6708 convert as per ANSI C and bits retain their traditional
6709 boolean style behaviour. Implemented bitfield support in
6717 * src/ds390/gen.c: bit v bitfield split
6718 * src/z80/gen.c: New support for bitfields
6719 * support/regression/tests/bitfields.c: reenabled z80,
6722 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6724 Rules 246.x, 247.x relate to bitfields, the others speed up
6725 access to xdata mapped I/O devices.
6727 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6729 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6731 Cleaned up genPackBits and genUnpackBits and added two helper
6732 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6733 for literal assignments in genPackBits (thanks to Frieder for
6739 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6741 Fixed bug #748310 (pointer to function type mishandled when the
6742 function name is omitted). Also fixed a SIGSEGV when a function
6743 attribute (reentrant, etc) is used on a non-function or on a
6744 function but misplaced before the parameter list.
6746 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6748 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
6749 * support/Util/SDCCerr.h,

6771 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6773 Made the constant following the "interrupt" keyword optional. If
6774 omitted, the function will not automatically be given an entry
6775 in the interrupt vector table (similar to #pragma NOIV, but
6776 less syntacticly kludgy). The interrupt number is also now
6777 range checked. Also fixed a bug in the high order bit example

6791 * src/SDCCicode.c (operandOperation): rewritten some ops
6792 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
6793 * src/SDCCsymt.c (computeType): literals are handled the same way as any
6795 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can

6798 unsigned, but are signed by default

7253 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
7254 the regression tests I'm not brave enough to enable 245.b, 245.c
7255 * doc/sdccman.lyx: added latex preamble for hyperref package.
7256 Using pdflatex this will give you a hyperlinked pdf file with
7257 bookmarks. (prepend '%' before /usepackage if this breaks something)

7306 * src/SDCCmain.c: linkOptions is changed to set *,
7307 added if/endif conditional macros to remove options help
7308 messages from optionsTable when a port is not configured, added
7309 support for the PIc16 port in the ports table, when executing
7310 the compiler with no port specified on command line, a default
7311 port is selected with the new macro DEFAULT_PORT which is
7312 defined in port.h, in setDefaultOptions() linkOptions is removed
7313 from initialization assignment, since now it is a set,
7314 parseCmdLine uses setParseWithComma for linkOptions, in
7315 linkEdit() linkOptions are accessed with new function indexSet()
7316 which returns the i'th item of a set variable. See SDCCset.c, in
7317 linkEdit() when calling buildCmdLine(), added linkOptions as
7318 last argument. Now users can pass arguments to gplink via the
7319 -Wl option, main() uses pic16glue() to glue up pic16 programs

7331 * src/pic16/glue.c: commented out some error producing lines
7332 * src/pic16/main.c: __config directives are commented out to stop
7333 gpasm complaining and test the linkage with gplink, _linkCmd and
7334 _asmCmd changed to be more gplink and gpasm friendly
7335 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7336 produced an error when parsed, peep rule 12 is added to utilize
7337 movff, but it is commented out since the pCode does not support
7338 yet a command with 2 address arguments
7340 2003-05-18 <johan AT balder>
7342 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
7343 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

8377 * src/SDCCicode.c: fixed array add
8379 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
8380 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
8381 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
8383 2003-01-04 <johan AT balder>
8385 * src/SDCCval.c (getNelements): fixed the initialized array of structures
8387 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8388 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
8390 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>

8400 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
8401 * src/mcs51/main.c: removed {bindir}{sep} from aslink
8403 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8405 * in \sdcc\as\mcs51\ changed these files in order to create an
8406 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
8407 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
8408 following files to include the previous two files: aslink.dsp,
8409 Makefile.aslink, Makefile.bcc, and Makefile.in.
8411 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8412 .adb instead of .cdb
8414 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8416 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8417 value from option --iram-size.
8419 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8421 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8424 2002-09-18 <wiml AT hhhh.org>
8426 * SDCClrange.h: exposed setFromRange() and setToRange()
8427 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8428 packRegsForAccUse() (bug 542397)
8429 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8430 multiple times and emitting the fetch operations more than once
8431 added aopGetUsesAcc() function to allow binary operators to
8432 fetch their operands in the correct order; made genMinus() emit
8433 compact code for X = LITERAL - Y
8435 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8436 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8437 sprintf() in line 1267.
8439 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8440 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8443 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8444 Changes to aslink (All the changes are marked with 'JCF'):
8446 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8449 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8450 area BSEG. Also moves, if possible, the DATA area down into the internal
8451 ram so more space is available.
8453 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8456 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8457 not bytes. Function summary() which creates a memory usage summary
8458 file with extension .mem. Reports of overlaping stack and small stack
8459 size. If the space for the stack is less than 16 bytes aslink trows a
8462 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8463 the 8051. Option 'y' for memory summary output file.
8465 Changes to sdcc (All the changes are marked with 'JCF'):
8467 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8469 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8470 overlaying area for it (uses RegBankUsed[4]).
8472 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8473 bank zero as used by default. By default aslink locates the stack
8474 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8475 the creation of the .mem file. Delegates the allocation of data area
8476 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8477 the begining of the stack area to aslink.
8479 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8480 glue() in SDCCglue.c creates an area for it.
8482 2002-09-03 Borut Razem <borut.razem AT siol.net>
8483 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8484 sdcc/src/pic/glue.c:
8485 introduced atexit() handler for teporay files removal in case of
8486 errors, assertions, ...
8488 2002-08-29 Borut Razem <borut.razem AT siol.net>
8489 * sdcc/support/cpp2/auto-host_vc_in.h:
8490 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8491 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8492 Maybe there is a similar problem with BORLANDC? It should be checked!
8494 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8495 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8496 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8497 was not executed, and the compiler (cl) launched a warning:
8498 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8500 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8501 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8503 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8504 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8506 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8507 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8508 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8509 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8510 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8511 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8512 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8513 - added Release configuration in VS projects
8514 - review of compiler an linker options
8515 - VC .exe files are generated in bin_vc directory, not to interfere
8516 with binaries generated from other projects (cygwin, mingw, bcc ...)
8518 * sdcc/src/yacc.dsp: added
8520 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8521 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8522 and insert the version number definitions from .version
8524 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8526 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8527 added - genarate auto-host.h using auto-host_vc_in.h as template
8530 removed from CVS, generated automatically
8532 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8533 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8535 2002-08-11 Borut Razem <borut.razem AT siol.net>
8536 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8538 2002-08-10 Borut Razem <borut.razem AT siol.net>
8539 * src/SDCCmain.c (main):
8540 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8541 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8542 The consequence was that some temporary files were not removed.
8545 unification of code in functions tempfilename() and tempfile():
8546 function tempnam() is defined in Visual Studio 6.0 and .NET
8548 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8550 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8551 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8552 - removed compiler command line option /WX: Treats all warnings as errors
8553 - update a list of source files, included into the project
8555 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8556 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8557 changed project type to Generic Project so that can be correcly converted to VS.NET project
8559 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8561 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8563 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8565 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8566 added return 0 statements after assert() to make compiler happy
8568 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8569 added newline in the def file to keep MSC compiler satisfied
8571 * sdcc/src/z80/gen.c:
8572 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8573 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8574 - solved MSC error in function aopDump()
8576 * sdcc_vc.h: define PREFIX as "\\sdcc"
8578 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8579 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
8581 2002-06-22 Scott Dattalo <scott AT dattalo.com>
8582 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
8583 - Rewrote the register banking algorithm.
8584 - Added pCode live-range analysis to registers (for now, only non-used and
8585 singly-used registers optimized away)
8587 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
8589 * 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.

8618 2002-03-28 Johan Knol <johan AT balder>
8620 * src/SDCCval.c: fixed bug #532436
8622 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8624 Added "char *Processor" field to the port structure.
8627 Added -p option. Allows port dependent processor to be specified.
8630 Initialized the new field char *Processor field to NULL in all ports
8633 Compiler generated registers for interrupt context saving
8634 were not getting allocated.
8636 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8639 Fixed left shift. Will promote the left side of a left shift
8640 if a) left shifting more than size of operand or b) when assigned
8641 to something size > size of left side
8643 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8645 tons of changes. Register allocation has been
8646 rewritten. Added customization for the various PICs. Flow
8647 analysis is restructured. ...
8653 Added. device.c is a PIC port hack to accomodate variations
8656 2002-03-13 Michael Hope <michaelh AT vroom>
8658 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
8660 2002-03-04 johanknol <johanknol AT manik>
