326 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
328 * device/lib/printf_large.c: removed inline assembly for portability and
329 readability. Use printf_fast if speed or size are more important.
330 * src/pic16/gen.c: removed conditions around use of DEBUGpc
331 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
333 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
335 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
336 prevent compiler warning
338 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
340 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
341 moved to level 0 and declared as static. Also they are explicit
342 placed in access bank. This was necessery because some times they
343 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
344 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
345 optimizations. Currently only compare to unsigned char is implemented,
346 * src/pic16/gen.c: added fReturnIdx array,
347 * (struct resolvedIfx) is moved to gen.h and made public,
348 * (struct _G): added sregsAlloc and sregsAllocSet fields,
349 * (aopForSym): added an optimization to directly store in stack of
350 the operand of a SEND iCode,
351 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
352 but as registers instead (AOP_REG) using the fReturnIdx array,
353 * (pic16_freeAsmop): remove the freed register from the
355 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
357 * (pic16_popGetTempRegCond): changed function prototype, now
358 function takes also a bitVector argument v which holds the current
359 set of registers that are allocated for stack access by aopForSym,
360 registers allocated in aopForSym for accessing stack symbols are not
361 any more part of the functions usedRegs field,
362 * (genCall): some times aopOp is called for a stack variable to be
363 send, aopForSym might perform the push, if this is true make sure
364 that genCall doesn't push the variable twice by testing _G.resDirect,
365 * (genFunction): changed testing for unspecified interrupt number
366 from 256 to INTNO_UNSPEC,
367 * modified selection scheme of frame pointer generation. Previously
368 if function did use local registers a frame pointer was generated,
369 now a frame pointer is generated only if function has arguments
370 (that need PLUSW2 register access), or has stack arguments, or the
371 compiler is not instructed to omit the frame pointer,
372 * (genEndFunction): before restoring local registers that were saved
373 in the function preamble, also restore the registers that *might*
374 have been allocated for stack access,
375 * (genRet): removed some old comments,
376 * (genCmp, the active (RN's) version): added a call to the
377 pic16_genCmp_special function to perform the compare with a more
378 robust and optimized way,
379 * (genInline): a feature has been added in inline code generation,
380 which allows a wildcard variable substitution when writing inline
381 assembly. Code is incomplete and experimental therefore undocumented,
382 * (genCast): changed order of aopOp for result and right to allow
383 aopForSym to directly load the result if possible,
384 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
385 perform an optimized compare on some selected special occasions,
386 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
387 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
388 generate an IVT any more,
389 * src/pic16/main.c (pic16_optionsTable): added command line option
391 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
392 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
394 * src/pic16/NOTES: Raphael Neider added in list of active developers
395 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
396 jumptable_end to prevent bug #,
397 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
398 inCond and outCond fields,
399 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
400 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
401 turn off register spilling,
402 * (packRegsForOneUse): synced with other ports' versions although it
403 is not used currently,
404 * (pic16_packRegisters): added an optimization while reading
405 structure bitfields, some registers may be saved (malloc code is
406 decreased by 80 bytes)
408 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
410 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
411 left is a bitfield, if yes, then don't optimize assignment. Perhaps
412 this can be optimized more?
414 2005-03-10 Raphael Neider <rneider AT web.de>
416 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
417 genNearPointerGet): (hopefully) fixed access to bitfields via
418 pointers (p->bitN = x; and x = p->bitN; failed)
420 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
422 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
424 2005-03-09 Raphael Neider <rneider AT web.de>
426 * src/SDCCopt.c (killDeadCode): fixed bug #1156016

1050 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1052 Adding support for replacing ljmps with sjmps in jumptables
1053 generated for switch statements. For now you need to set the
1054 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1055 Now 4 algorithms for mcs51 jumptable generation are used:
1056 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1057 addresses loaded pc-relative for up to 112 cases and stack-pushing
1058 target addresses loaded with offset from dptr for up to 256 cases.

1088 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1090 * added libc directory. The current version of LibC contains string
1091 functions, ctype functions and macros and some functions of the
1092 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1093 be extensively tested in the future. Standard disclaimer here.
1094 Library is not automatically build yet. But one can build it by
1095 invoking 'make' inside the libc directory.

1106 * (pic16_storeForReturn): optimized return of 0,
1107 * (genCmp): experimental code for new genCmp which uses PIC18's
1108 special compare&skip instructions. Initial tests fail some times
1109 with variables grater than 1 byte in size, so new code is disabled,
1110 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1112 * (genCast): began a fix to optimize the casting of a bit to another
1113 bit, now assigning a bitfield to another bitfield will fail, sorry,
1114 * src/pic16/main.c: disabled the use of lr-support feature,
1115 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

1118 bits with offset (case PO_GPR_BIT),
1119 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
1121 * (isBankInstruction): modified to return 0 for no banking instruction,
1122 and 1 for banking instruction,
1123 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1124 caused stop processing pCodes after a inline assembly block,
1125 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1126 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1127 registers when it shouldn't,
1128 * src/pic16/ralloc.c (allocReg): add preliminary support for
1129 supporting a limited set of temporary registers,
1131 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1133 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1134 genDataPointerSet): ensure assignments always copy in MSB to LSB
1136 (loadRegFromAop): recognize CLRH optimization,
1137 (genFunction): optimize RECEIVE iCodes in reentrant functions
1139 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1141 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4139 loaded with the linker search paths (-L arguments) and the libraries
4140 to be linked with the current source (-l arguments). Changes
4141 currently will affect only the pic16 port.
4142 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4143 include path the port specific paths and port specific libraries,
4144 * gplink command now contains the $3 argument,
4145 * src/pic16/device.h,

4162 Documenting changes from previous commits.
4163 * configure.in (version 1.56),
4164 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4165 when generating output files to configure the pic16 library,
4166 but now I've commented it out, since gputils aren't installed in the
4167 SF compile farm, so library won't compile
4169 * device/lib/Makefile.in (version 1.56): initially I've added in
4170 target 'all' the prerequestive 'model-pic16' so it compiled the
4171 pic16 library, but now I've commented it out for the same reasons
4173 * added targets 'model-pic16' and 'objects-pic16' to compile the
4175 * added target 'port-specific-objects-pic16' to handle the
4176 generated libraries and copy them into the build/ directory
4177 * added target 'clean-intermediate-pic16' to clean intermediate
4178 files into pic16 directory
4179 * in target 'installdirs' added line to create directory pic16 in

4488 pic16createInterruptVect: is modified
4489 pic16printPublics: is modified to emit 'global' assembler directives,
4490 added pic16_printExterns to print extern symbols,
4491 pic16glue: initializes stack/frame pointer in the beginning of
4492 the assembly output. Temporary hack, will be corrected later,
4493 because gplink yet does not support stack and SDCC does not
4494 yet support a type of crt0.o object to create the final binary.
4496 * Removed many lines that contain 8051 legacy code.
4497 * The code is finally placed under a 'code' directive.
4498 * Added port specific options.
4500 * _process_pragma: simplified since now we do not need *special*
4501 include file to define SFR registers. But a separate header
4502 will be needed. This will be developed later.
4503 * _pic16_parseOptions: added, parses port specific options:
4504 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4505 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4506 --preplace-udata-with=
4508 * _pic16_setDefaultOptions: modified to initialize section names,
4509 but hack is temporarly out of order since it needs improvement.
4510 * _pic16_genAssemblerPreamble: configuration words are emitted by
4511 their address instead of their name. This part is incomplete and
4512 supports only the 18Fxx2 devices. Other devices will emit an error
4513 during assembly since they do not contain the same set of config
4515 * _pic16_genIVT: is modified,
4517 * pcode.c: added definitions for some hardware registers that are needed
4519 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4520 All PCI entries are updated. Now LFSR is supported.
4521 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4522 * added pic16_newpCodeOpLit2 to support instructions with
4523 two literal arguments
4524 * pic16_pCode2str: corrected code that emits assembler instructions
4525 with two literal operands and those that have an access bit modifier
4526 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4527 this fixes a bug which caused some labels to be lost, when an
4528 assembler directive was added, i.e. banksel,
4529 * pic16_FixRegisterBanking: improved logic that causes the insertion
4531 * InlineFunction: functions that are called once, are not any more
4532 inlined. This can be a port option in the future,
4534 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4536 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4537 hold the corresponding uninitialized symbols,
4538 * pic16_allocProcessorRegister: registers have explicit marked the
4540 * pic16_allocInternalRegister: registers are explicit marked as
4542 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4543 processing list, so bit registers were lost,
4546 * ralloc.h: added field 'accessBank' and original symbol operand
4547 in register definition,
4548 * removed the field isMapped from register definition,
4550 ** Several functions have been removed from various sources:
4551 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4552 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4553 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4554 pic16_assignRelocatableRegisters
4556 ** others have been introduced:
4557 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4558 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4560 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4562 * support/scripts/inc2h.pl: changed definition of BIT_AT
4563 to emit 'sbit at' instead of 'bit at'. This was a request.
4565 PIC16 port related preliminary changes:
4566 * gen.c: prefixed function popRegFromString with
4567 pic16_ and all references to it corrected
4568 * pcode.c: all pic16_pc_* hardware registers prefixed
4569 with underscore (_),
4570 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4571 * ralloc.c: newReg(): when register is REG_SFR then
4572 set address to rIdx,
4573 pic16_allocProcessorRegister(): marks register wasUsed=0
4574 pic16_writeUsedRegs(): added a call to assign processor
4575 registers via pic16_assignFixedRegisters
4577 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4579 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4580 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4581 variables in unused register banks. Also the SSEG is placed
4582 wherever there is enough space for it, and IDATA can be anywhere
4583 in internal RAM. For now compile using -Wl-Y[stack_size].
4584 The mem file is different for this option as well, since it
4585 makes no sense of talking about DSEG lenght.
4587 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4589 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4590 in certain cases, e.g. when ROM assignment, patch provided
4591 from Albert den Haan.

4832 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4834 * src/SDCCast.c (decorateType): disabled a transformation I added in
4835 revision 1.188 (access to fields of a structure at an absolute address);
4836 it breaks with bitfields, extern declarations, and gcse analysis.
4837 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4838 could be assigned through a pointer, so don't complain.
4839 * src/SDCCast.c (astErrors),
4841 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

4943 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
4944 uninitialized variables) for the mcs51. Set environment variable
4945 SDCC_GENRAMCLEAR to test.
4946 xdata initialization slightly shorter
4948 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5595 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5596 fetching of the pointer
5597 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5598 copied from genNearPointerSet()
5599 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5600 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5616 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5617 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5618 type for bits was changed. It resulted in bit variables becoming
5619 global, which is not permitted in PIC 14 assembly output.
5621 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5623 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5636 A few small changes that speed up the peephole optimizer.
5640 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5642 Try to make the peephole optimizer smarter by maintaining
5643 an association between the assembly source code and the
5644 iCodes that originated them. Put this information to use
5645 with a new peephole rule condition "notVolatile" so that
5646 the rules can be aggressive yet still safe.
5651 * src/mcs51/peeph.def
5653 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5657 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5658 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5659 if the left or right operand symbols have the accuse flag set.
5661 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5663 Changed the type of the result of the ! (NOT) operator to char;
5664 previously it returned the same type as the source. This allows
5665 us to eliminate all the genFloatNot functions (all of its target
5666 implementations were very buggy) since !float can use the same

5678 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5679 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5680 during interrupts. Ensure WSAVE is located at a shared bank address.
5681 2. Fixed page selection in some places
5682 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5683 the registers name strings.
5684 4. Fixed "signed / unsigned compare" compiler warnings.
5685 5. The PIC port manages its own allocation of the general purpose
5686 registers, but makes no attempt to reuse them. As a result when
5687 compiling it soon runs out of general purpose registers. Some
5688 additional code was added to the files pcode.c and device.c to walk
5689 through the function call tree and rename the registers so that they
5699 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5700 genPlus() & genMinus() when the result is the same as left or right

5706 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5708 Made bitfield a distinct type from bit so that bitfields
5709 convert as per ANSI C and bits retain their traditional
5710 boolean style behaviour. Implemented bitfield support in
5718 * src/ds390/gen.c: bit v bitfield split
5719 * src/z80/gen.c: New support for bitfields
5720 * support/regression/tests/bitfields.c: reenabled z80,
5723 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5725 Rules 246.x, 247.x relate to bitfields, the others speed up
5726 access to xdata mapped I/O devices.
5728 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5730 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5732 Cleaned up genPackBits and genUnpackBits and added two helper
5733 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5734 for literal assignments in genPackBits (thanks to Frieder for
5740 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5742 Fixed bug #748310 (pointer to function type mishandled when the
5743 function name is omitted). Also fixed a SIGSEGV when a function
5744 attribute (reentrant, etc) is used on a non-function or on a
5745 function but misplaced before the parameter list.
5747 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5749 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5750 * support/Util/SDCCerr.h,
5751 * support/Util/SDCCerr.c: Added func attr misuse error msg

5772 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5774 Made the constant following the "interrupt" keyword optional. If
5775 omitted, the function will not automatically be given an entry
5776 in the interrupt vector table (similar to #pragma NOIV, but
5777 less syntacticly kludgy). The interrupt number is also now
5778 range checked. Also fixed a bug in the high order bit example

5789 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
5791 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
5792 * src/SDCCicode.c (operandOperation): rewritten some ops
5793 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5794 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5796 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5797 be re-activated by defining REDUCE_LITERALS)
5798 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5799 unsigned, but are signed by default
5800 * src/SDCCval.c (constVal): rearranged
5801 * src/SDCCval.c (valMod): preliminary fix
5802 * src/SDCCval.c (valCastLiteral): use TYPE_* types

5844 constants are unsigned; added recognition of "u" flag for unsigned
5845 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
5846 * src/SDCCval.c (valDiv, valMod): fixed signdness
5847 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
5848 signedness of modulo, left and right shift

6307 * src/SDCCmain.c: linkOptions is changed to set *,
6308 added if/endif conditional macros to remove options help
6309 messages from optionsTable when a port is not configured, added
6310 support for the PIc16 port in the ports table, when executing
6311 the compiler with no port specified on command line, a default
6312 port is selected with the new macro DEFAULT_PORT which is
6313 defined in port.h, in setDefaultOptions() linkOptions is removed
6314 from initialization assignment, since now it is a set,
6315 parseCmdLine uses setParseWithComma for linkOptions, in
6316 linkEdit() linkOptions are accessed with new function indexSet()
6317 which returns the i'th item of a set variable. See SDCCset.c, in
6318 linkEdit() when calling buildCmdLine(), added linkOptions as
6319 last argument. Now users can pass arguments to gplink via the
6320 -Wl option, main() uses pic16glue() to glue up pic16 programs

6332 * src/pic16/glue.c: commented out some error producing lines
6333 * src/pic16/main.c: __config directives are commented out to stop
6334 gpasm complaining and test the linkage with gplink, _linkCmd and
6335 _asmCmd changed to be more gplink and gpasm friendly
6336 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6337 produced an error when parsed, peep rule 12 is added to utilize
6338 movff, but it is commented out since the pCode does not support
6339 yet a command with 2 address arguments
6341 2003-05-18 <johan AT balder>
6343 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6370 2003-05-11 Borut Razem <borut.razem AT siol.net>
6372 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6373 the path of bin directory, so that PATH is the only env. variable, which has to be set
6374 in case of standard installation.
6375 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

7407 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7408 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7409 following files to include the previous two files: aslink.dsp,
7410 Makefile.aslink, Makefile.bcc, and Makefile.in.
7412 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7413 .adb instead of .cdb
7415 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7417 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7418 value from option --iram-size.
7420 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7422 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7425 2002-09-18 <wiml AT hhhh.org>
7427 * SDCClrange.h: exposed setFromRange() and setToRange()
7428 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7429 packRegsForAccUse() (bug 542397)
7430 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7431 multiple times and emitting the fetch operations more than once
7432 added aopGetUsesAcc() function to allow binary operators to
7433 fetch their operands in the correct order; made genMinus() emit
7434 compact code for X = LITERAL - Y
7436 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7437 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7438 sprintf() in line 1267.
7440 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7441 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7444 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7445 Changes to aslink (All the changes are marked with 'JCF'):
7447 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7450 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7451 area BSEG. Also moves, if possible, the DATA area down into the internal
7452 ram so more space is available.
7454 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7457 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7458 not bytes. Function summary() which creates a memory usage summary
7459 file with extension .mem. Reports of overlaping stack and small stack
7460 size. If the space for the stack is less than 16 bytes aslink trows a
7463 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7464 the 8051. Option 'y' for memory summary output file.
7466 Changes to sdcc (All the changes are marked with 'JCF'):
7468 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7470 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7471 overlaying area for it (uses RegBankUsed[4]).
7473 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7474 bank zero as used by default. By default aslink locates the stack
7475 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7476 the creation of the .mem file. Delegates the allocation of data area
7477 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7478 the begining of the stack area to aslink.
7480 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7481 glue() in SDCCglue.c creates an area for it.
7483 2002-09-03 Borut Razem <borut.razem AT siol.net>
7484 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7485 sdcc/src/pic/glue.c:
7486 introduced atexit() handler for teporay files removal in case of
7487 errors, assertions, ...
7489 2002-08-29 Borut Razem <borut.razem AT siol.net>
7490 * sdcc/support/cpp2/auto-host_vc_in.h:
7491 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7492 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7493 Maybe there is a similar problem with BORLANDC? It should be checked!
7495 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7496 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7497 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7498 was not executed, and the compiler (cl) launched a warning:
7499 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7501 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7502 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7504 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7505 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7507 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7508 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7509 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7510 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7511 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7512 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7513 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7514 - added Release configuration in VS projects
7515 - review of compiler an linker options
7516 - VC .exe files are generated in bin_vc directory, not to interfere
7517 with binaries generated from other projects (cygwin, mingw, bcc ...)
7519 * sdcc/src/yacc.dsp: added
7521 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7522 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7523 and insert the version number definitions from .version
7525 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7527 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7528 added - genarate auto-host.h using auto-host_vc_in.h as template
7531 removed from CVS, generated automatically
7533 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7534 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7536 2002-08-11 Borut Razem <borut.razem AT siol.net>
7537 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7539 2002-08-10 Borut Razem <borut.razem AT siol.net>
7540 * src/SDCCmain.c (main):
7541 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7542 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7543 The consequence was that some temporary files were not removed.
7546 unification of code in functions tempfilename() and tempfile():
7547 function tempnam() is defined in Visual Studio 6.0 and .NET
7549 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7551 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7552 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7553 - removed compiler command line option /WX: Treats all warnings as errors
7554 - update a list of source files, included into the project
7556 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7557 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7558 changed project type to Generic Project so that can be correcly converted to VS.NET project
7560 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7562 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7564 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7566 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7567 added return 0 statements after assert() to make compiler happy
7569 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7570 added newline in the def file to keep MSC compiler satisfied
7572 * sdcc/src/z80/gen.c:
7573 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7574 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7575 - solved MSC error in function aopDump()
7577 * sdcc_vc.h: define PREFIX as "\\sdcc"
7579 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7580 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7583 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7584 - Rewrote the register banking algorithm.
7585 - Added pCode live-range analysis to registers (for now, only non-used and
7586 singly-used registers optimized away)
7588 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

7619 2002-03-28 Johan Knol <johan AT balder>
7621 * src/SDCCval.c: fixed bug #532436
7623 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7625 Added "char *Processor" field to the port structure.
7628 Added -p option. Allows port dependent processor to be specified.
7631 Initialized the new field char *Processor field to NULL in all ports
7634 Compiler generated registers for interrupt context saving
7635 were not getting allocated.
7637 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7640 Fixed left shift. Will promote the left side of a left shift
7641 if a) left shifting more than size of operand or b) when assigned
7642 to something size > size of left side
7644 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7646 tons of changes. Register allocation has been
7647 rewritten. Added customization for the various PICs. Flow

7752 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7754 * sdcc/src/SDCCloop.c:
7755 Previous fix was not good. basic blocks that have "break" or "return" are
7756 not really partof a loop , but live ranges used in these blocks should
7757 be live thru the entire loop, so set partOfLoop but don't add them to
7760 2002-02-21 <johan AT FRIJA>
7762 * src/SDCCcse.c: fixed bug #514308
7764 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

7768 statement inside a loop, it was not being considered part of the loop.
7770 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7772 2002-02-10 Karl Bongers <karl AT turbobit.com>
7775 Fixed up SDCDB debugger somewhat. Updated debugger/README
7776 with lots of comments and notes.
7778 * device/examples/test2.c:
7779 Fix bug, "red" variable not being initialized(compiler complained).

7830 set preprocessor defines (depending on options)
7832 * src/SDCCicode.c, src/SDCCicode.h:
7833 changes made to handle multiple sends & receives
7836 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
