344 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
346 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
348 * device/lib/printf_large.c: removed inline assembly for portability and
349 readability. Use printf_fast if speed or size are more important.
350 * src/pic16/gen.c: removed conditions around use of DEBUGpc
351 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
353 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
355 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
356 prevent compiler warning
358 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
360 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
361 moved to level 0 and declared as static. Also they are explicit
362 placed in access bank. This was necessery because some times they
363 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
364 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
365 optimizations. Currently only compare to unsigned char is implemented,
366 * src/pic16/gen.c: added fReturnIdx array,
367 * (struct resolvedIfx) is moved to gen.h and made public,
368 * (struct _G): added sregsAlloc and sregsAllocSet fields,
369 * (aopForSym): added an optimization to directly store in stack of
370 the operand of a SEND iCode,
371 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
372 but as registers instead (AOP_REG) using the fReturnIdx array,
373 * (pic16_freeAsmop): remove the freed register from the
375 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
377 * (pic16_popGetTempRegCond): changed function prototype, now
378 function takes also a bitVector argument v which holds the current
379 set of registers that are allocated for stack access by aopForSym,
380 registers allocated in aopForSym for accessing stack symbols are not
381 any more part of the functions usedRegs field,
382 * (genCall): some times aopOp is called for a stack variable to be
383 send, aopForSym might perform the push, if this is true make sure
384 that genCall doesn't push the variable twice by testing _G.resDirect,
385 * (genFunction): changed testing for unspecified interrupt number
386 from 256 to INTNO_UNSPEC,
387 * modified selection scheme of frame pointer generation. Previously
388 if function did use local registers a frame pointer was generated,
389 now a frame pointer is generated only if function has arguments
390 (that need PLUSW2 register access), or has stack arguments, or the
391 compiler is not instructed to omit the frame pointer,
392 * (genEndFunction): before restoring local registers that were saved
393 in the function preamble, also restore the registers that *might*
394 have been allocated for stack access,
395 * (genRet): removed some old comments,
396 * (genCmp, the active (RN's) version): added a call to the
397 pic16_genCmp_special function to perform the compare with a more
398 robust and optimized way,
399 * (genInline): a feature has been added in inline code generation,
400 which allows a wildcard variable substitution when writing inline
401 assembly. Code is incomplete and experimental therefore undocumented,
402 * (genCast): changed order of aopOp for result and right to allow
403 aopForSym to directly load the result if possible,
404 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
405 perform an optimized compare on some selected special occasions,
406 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
407 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
408 generate an IVT any more,
409 * src/pic16/main.c (pic16_optionsTable): added command line option
411 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
412 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
414 * src/pic16/NOTES: Raphael Neider added in list of active developers
415 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
416 jumptable_end to prevent bug #,
417 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
418 inCond and outCond fields,
419 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
420 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
421 turn off register spilling,
422 * (packRegsForOneUse): synced with other ports' versions although it
423 is not used currently,
424 * (pic16_packRegisters): added an optimization while reading
425 structure bitfields, some registers may be saved (malloc code is
426 decreased by 80 bytes)
428 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
430 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
431 left is a bitfield, if yes, then don't optimize assignment. Perhaps
432 this can be optimized more?
434 2005-03-10 Raphael Neider <rneider AT web.de>
436 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
437 genNearPointerGet): (hopefully) fixed access to bitfields via
438 pointers (p->bitN = x; and x = p->bitN; failed)
440 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
442 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
444 2005-03-09 Raphael Neider <rneider AT web.de>

1072 Adding support for replacing ljmps with sjmps in jumptables
1073 generated for switch statements. For now you need to set the
1074 environment variable SDCC_SJMP_JUMPTABLE to enable this.
1075 Now 4 algorithms for mcs51 jumptable generation are used:
1076 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
1077 addresses loaded pc-relative for up to 112 cases and stack-pushing
1078 target addresses loaded with offset from dptr for up to 256 cases.

1108 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
1110 * added libc directory. The current version of LibC contains string
1111 functions, ctype functions and macros and some functions of the
1112 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
1113 be extensively tested in the future. Standard disclaimer here.
1114 Library is not automatically build yet. But one can build it by
1115 invoking 'make' inside the libc directory.

1126 * (pic16_storeForReturn): optimized return of 0,
1127 * (genCmp): experimental code for new genCmp which uses PIC18's
1128 special compare&skip instructions. Initial tests fail some times
1129 with variables grater than 1 byte in size, so new code is disabled,
1130 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
1132 * (genCast): began a fix to optimize the casting of a bit to another
1133 bit, now assigning a bitfield to another bitfield will fail, sorry,
1134 * src/pic16/main.c: disabled the use of lr-support feature,
1135 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

1142 and 1 for banking instruction,
1143 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
1144 caused stop processing pCodes after a inline assembly block,
1145 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
1146 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
1147 registers when it shouldn't,
1148 * src/pic16/ralloc.c (allocReg): add preliminary support for
1149 supporting a limited set of temporary registers,
1151 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1153 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
1154 genDataPointerSet): ensure assignments always copy in MSB to LSB
1156 (loadRegFromAop): recognize CLRH optimization,
1157 (genFunction): optimize RECEIVE iCodes in reentrant functions
1159 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1161 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

4159 loaded with the linker search paths (-L arguments) and the libraries
4160 to be linked with the current source (-l arguments). Changes
4161 currently will affect only the pic16 port.
4162 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
4163 include path the port specific paths and port specific libraries,
4164 * gplink command now contains the $3 argument,
4165 * src/pic16/device.h,

4182 Documenting changes from previous commits.
4183 * configure.in (version 1.56),
4184 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
4185 when generating output files to configure the pic16 library,
4186 but now I've commented it out, since gputils aren't installed in the
4187 SF compile farm, so library won't compile
4189 * device/lib/Makefile.in (version 1.56): initially I've added in
4190 target 'all' the prerequestive 'model-pic16' so it compiled the
4191 pic16 library, but now I've commented it out for the same reasons
4193 * added targets 'model-pic16' and 'objects-pic16' to compile the
4195 * added target 'port-specific-objects-pic16' to handle the
4196 generated libraries and copy them into the build/ directory
4197 * added target 'clean-intermediate-pic16' to clean intermediate
4198 files into pic16 directory
4199 * in target 'installdirs' added line to create directory pic16 in

4203 added lines to copy all header files to installation path,
4204 * in target 'installdirs' added line create directory for pic16
4205 headers in the installation path

4487 * src/ds390/gen.c (genRightShift): fixed bug #870788
4488 * src/SDCCast.c (decorateType): fixed bug #870781
4490 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
4492 PIC16 port related changes:
4493 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
4494 added variable stackPos,
4496 * gen.c: genCall, assignResultValue: added support for
4497 pushing/retrieving function parameters to/from stack,
4498 genFunction,genEndFunction: setup stack frame for the
4500 genAddrOf: will be changed according to bug 863624
4502 * added files genutils.c and genutils.h which contain gen*
4503 debugged and optimised functions extracted from gen.c
4505 * glue.c: added variable 'externs' which holds extern symbols,
4506 pic16emitRegularMap: is modified to properly handle relocatable
4507 symbols under the new scheme,
4508 pic16createInterruptVect: is modified
4509 pic16printPublics: is modified to emit 'global' assembler directives,
4510 added pic16_printExterns to print extern symbols,
4511 pic16glue: initializes stack/frame pointer in the beginning of
4512 the assembly output. Temporary hack, will be corrected later,
4513 because gplink yet does not support stack and SDCC does not
4514 yet support a type of crt0.o object to create the final binary.
4516 * Removed many lines that contain 8051 legacy code.
4517 * The code is finally placed under a 'code' directive.
4518 * Added port specific options.
4520 * _process_pragma: simplified since now we do not need *special*
4521 include file to define SFR registers. But a separate header
4522 will be needed. This will be developed later.
4523 * _pic16_parseOptions: added, parses port specific options:
4524 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
4525 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
4526 --preplace-udata-with=
4528 * _pic16_setDefaultOptions: modified to initialize section names,
4529 but hack is temporarly out of order since it needs improvement.
4530 * _pic16_genAssemblerPreamble: configuration words are emitted by
4531 their address instead of their name. This part is incomplete and
4532 supports only the 18Fxx2 devices. Other devices will emit an error
4533 during assembly since they do not contain the same set of config
4535 * _pic16_genIVT: is modified,
4537 * pcode.c: added definitions for some hardware registers that are needed
4539 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
4540 All PCI entries are updated. Now LFSR is supported.
4541 * Removed pic16_pciTRIS is mentioned by mdubuc in source
4542 * added pic16_newpCodeOpLit2 to support instructions with
4543 two literal arguments
4544 * pic16_pCode2str: corrected code that emits assembler instructions
4545 with two literal operands and those that have an access bit modifier
4546 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
4547 this fixes a bug which caused some labels to be lost, when an
4548 assembler directive was added, i.e. banksel,
4549 * pic16_FixRegisterBanking: improved logic that causes the insertion
4551 * InlineFunction: functions that are called once, are not any more
4552 inlined. This can be a port option in the future,
4554 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
4556 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
4557 hold the corresponding uninitialized symbols,
4558 * pic16_allocProcessorRegister: registers have explicit marked the
4560 * pic16_allocInternalRegister: registers are explicit marked as
4562 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
4563 processing list, so bit registers were lost,
4566 * ralloc.h: added field 'accessBank' and original symbol operand
4567 in register definition,
4568 * removed the field isMapped from register definition,
4570 ** Several functions have been removed from various sources:
4571 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
4572 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
4573 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
4574 pic16_assignRelocatableRegisters
4576 ** others have been introduced:
4577 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
4578 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
4580 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
4582 * support/scripts/inc2h.pl: changed definition of BIT_AT
4583 to emit 'sbit at' instead of 'bit at'. This was a request.
4585 PIC16 port related preliminary changes:
4586 * gen.c: prefixed function popRegFromString with
4587 pic16_ and all references to it corrected
4588 * pcode.c: all pic16_pc_* hardware registers prefixed
4589 with underscore (_),
4590 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
4591 * ralloc.c: newReg(): when register is REG_SFR then
4592 set address to rIdx,
4593 pic16_allocProcessorRegister(): marks register wasUsed=0
4594 pic16_writeUsedRegs(): added a call to assign processor
4595 registers via pic16_assignFixedRegisters
4597 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4599 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
4600 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
4601 variables in unused register banks. Also the SSEG is placed
4602 wherever there is enough space for it, and IDATA can be anywhere
4603 in internal RAM. For now compile using -Wl-Y[stack_size].
4604 The mem file is different for this option as well, since it
4605 makes no sense of talking about DSEG lenght.
4607 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
4609 * src/SDCClrange.c: fixed bug 869095 that caused segfault
4610 in certain cases, e.g. when ROM assignment, patch provided
4611 from Albert den Haan.
4613 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

4852 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4854 * src/SDCCast.c (decorateType): disabled a transformation I added in
4855 revision 1.188 (access to fields of a structure at an absolute address);
4856 it breaks with bitfields, extern declarations, and gcse analysis.
4857 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
4858 could be assigned through a pointer, so don't complain.
4859 * src/SDCCast.c (astErrors),
4861 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

5519 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5521 Fixed bug #621531 (const & volatile confusion in the type chain).
5522 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

5615 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
5616 fetching of the pointer
5617 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
5618 copied from genNearPointerSet()
5619 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
5620 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

5636 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5637 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
5638 type for bits was changed. It resulted in bit variables becoming
5639 global, which is not permitted in PIC 14 assembly output.
5641 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5643 * doc/sdccman.lyx: various additions and updates. Rearranged sections

5656 A few small changes that speed up the peephole optimizer.
5660 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5662 Try to make the peephole optimizer smarter by maintaining
5663 an association between the assembly source code and the
5664 iCodes that originated them. Put this information to use
5665 with a new peephole rule condition "notVolatile" so that
5666 the rules can be aggressive yet still safe.
5671 * src/mcs51/peeph.def
5673 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5677 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
5678 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
5679 if the left or right operand symbols have the accuse flag set.
5681 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5683 Changed the type of the result of the ! (NOT) operator to char;
5684 previously it returned the same type as the source. This allows
5685 us to eliminate all the genFloatNot functions (all of its target
5686 implementations were very buggy) since !float can use the same

5698 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
5699 1. Interrupt would not compile properly. Ensure PCLATH register is saved
5700 during interrupts. Ensure WSAVE is located at a shared bank address.
5701 2. Fixed page selection in some places
5702 3. Fixed BTFSS/C to where necessary use registers directly and not simply
5703 the registers name strings.
5704 4. Fixed "signed / unsigned compare" compiler warnings.
5705 5. The PIC port manages its own allocation of the general purpose
5706 registers, but makes no attempt to reuse them. As a result when
5707 compiling it soon runs out of general purpose registers. Some
5708 additional code was added to the files pcode.c and device.c to walk
5709 through the function call tree and rename the registers so that they
5719 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
5720 genPlus() & genMinus() when the result is the same as left or right

5726 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5728 Made bitfield a distinct type from bit so that bitfields
5729 convert as per ANSI C and bits retain their traditional
5730 boolean style behaviour. Implemented bitfield support in
5738 * src/ds390/gen.c: bit v bitfield split
5739 * src/z80/gen.c: New support for bitfields
5740 * support/regression/tests/bitfields.c: reenabled z80,
5743 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5745 Rules 246.x, 247.x relate to bitfields, the others speed up
5746 access to xdata mapped I/O devices.
5748 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
5750 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5752 Cleaned up genPackBits and genUnpackBits and added two helper
5753 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
5754 for literal assignments in genPackBits (thanks to Frieder for
5760 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5762 Fixed bug #748310 (pointer to function type mishandled when the
5763 function name is omitted). Also fixed a SIGSEGV when a function
5764 attribute (reentrant, etc) is used on a non-function or on a
5765 function but misplaced before the parameter list.
5767 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
5769 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
5770 * support/Util/SDCCerr.h,

5792 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5794 Made the constant following the "interrupt" keyword optional. If
5795 omitted, the function will not automatically be given an entry
5796 in the interrupt vector table (similar to #pragma NOIV, but
5797 less syntacticly kludgy). The interrupt number is also now
5798 range checked. Also fixed a bug in the high order bit example

5812 * src/SDCCicode.c (operandOperation): rewritten some ops
5813 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
5814 * src/SDCCsymt.c (computeType): literals are handled the same way as any
5816 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
5817 be re-activated by defining REDUCE_LITERALS)
5818 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
5819 unsigned, but are signed by default
5820 * src/SDCCval.c (constVal): rearranged
5821 * src/SDCCval.c (valMod): preliminary fix
5822 * src/SDCCval.c (valCastLiteral): use TYPE_* types

6327 * src/SDCCmain.c: linkOptions is changed to set *,
6328 added if/endif conditional macros to remove options help
6329 messages from optionsTable when a port is not configured, added
6330 support for the PIc16 port in the ports table, when executing
6331 the compiler with no port specified on command line, a default
6332 port is selected with the new macro DEFAULT_PORT which is
6333 defined in port.h, in setDefaultOptions() linkOptions is removed
6334 from initialization assignment, since now it is a set,
6335 parseCmdLine uses setParseWithComma for linkOptions, in
6336 linkEdit() linkOptions are accessed with new function indexSet()
6337 which returns the i'th item of a set variable. See SDCCset.c, in
6338 linkEdit() when calling buildCmdLine(), added linkOptions as
6339 last argument. Now users can pass arguments to gplink via the
6340 -Wl option, main() uses pic16glue() to glue up pic16 programs

6352 * src/pic16/glue.c: commented out some error producing lines
6353 * src/pic16/main.c: __config directives are commented out to stop
6354 gpasm complaining and test the linkage with gplink, _linkCmd and
6355 _asmCmd changed to be more gplink and gpasm friendly
6356 * src/pic16/peeph.def: peep rule 3 is commented out, since it
6357 produced an error when parsed, peep rule 12 is added to utilize
6358 movff, but it is commented out since the pCode does not support
6359 yet a command with 2 address arguments
6361 2003-05-18 <johan AT balder>
6363 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

6390 2003-05-11 Borut Razem <borut.razem AT siol.net>
6392 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
6393 the path of bin directory, so that PATH is the only env. variable, which has to be set
6394 in case of standard installation.

7409 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
7411 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7412 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
7413 * support/regression/tests/bug-524697.c: fit mem usage into 8032
7415 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
7416 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
7418 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
7419 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
7421 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
7422 * src/mcs51/main.c: removed {bindir}{sep} from aslink
7424 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7426 * in \sdcc\as\mcs51\ changed these files in order to create an
7427 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
7428 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
7429 following files to include the previous two files: aslink.dsp,
7430 Makefile.aslink, Makefile.bcc, and Makefile.in.
7432 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
7433 .adb instead of .cdb
7435 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7437 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
7438 value from option --iram-size.
7440 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7442 * \sdcc\as\mcs51\lklist.c: added boundary check before using
7445 2002-09-18 <wiml AT hhhh.org>
7447 * SDCClrange.h: exposed setFromRange() and setToRange()
7448 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
7449 packRegsForAccUse() (bug 542397)
7450 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
7451 multiple times and emitting the fetch operations more than once
7452 added aopGetUsesAcc() function to allow binary operators to
7453 fetch their operands in the correct order; made genMinus() emit
7454 compact code for X = LITERAL - Y
7456 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7457 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
7458 sprintf() in line 1267.
7460 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7461 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
7464 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7465 Changes to aslink (All the changes are marked with 'JCF'):
7467 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
7470 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
7471 area BSEG. Also moves, if possible, the DATA area down into the internal
7472 ram so more space is available.
7474 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
7477 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
7478 not bytes. Function summary() which creates a memory usage summary
7479 file with extension .mem. Reports of overlaping stack and small stack
7480 size. If the space for the stack is less than 16 bytes aslink trows a
7483 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
7484 the 8051. Option 'y' for memory summary output file.
7486 Changes to sdcc (All the changes are marked with 'JCF'):
7488 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
7490 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
7491 overlaying area for it (uses RegBankUsed[4]).
7493 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
7494 bank zero as used by default. By default aslink locates the stack
7495 (equivalent to --stack-after-data). Pass option 'y' to aslink for
7496 the creation of the .mem file. Delegates the allocation of data area
7497 to aslink (it is not longer 0x30 by default). If --stack-loc passes
7498 the begining of the stack area to aslink.
7500 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
7501 glue() in SDCCglue.c creates an area for it.
7503 2002-09-03 Borut Razem <borut.razem AT siol.net>
7504 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
7505 sdcc/src/pic/glue.c:
7506 introduced atexit() handler for teporay files removal in case of
7507 errors, assertions, ...
7509 2002-08-29 Borut Razem <borut.razem AT siol.net>
7510 * sdcc/support/cpp2/auto-host_vc_in.h:
7511 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
7512 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
7513 Maybe there is a similar problem with BORLANDC? It should be checked!
7515 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
7516 corrected improper use of assert: the assignment to clr variable was done inside the assert.
7517 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
7518 was not executed, and the compiler (cl) launched a warning:
7519 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
7521 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
7522 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
7524 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
7525 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
7527 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7528 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
7529 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
7530 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7531 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
7532 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
7533 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
7534 - added Release configuration in VS projects
7535 - review of compiler an linker options
7536 - VC .exe files are generated in bin_vc directory, not to interfere
7537 with binaries generated from other projects (cygwin, mingw, bcc ...)
7539 * sdcc/src/yacc.dsp: added
7541 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
7542 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
7543 and insert the version number definitions from .version
7545 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
7547 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
7548 added - genarate auto-host.h using auto-host_vc_in.h as template
7551 removed from CVS, generated automatically
7553 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
7554 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
7556 2002-08-11 Borut Razem <borut.razem AT siol.net>
7557 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
7559 2002-08-10 Borut Razem <borut.razem AT siol.net>
7560 * src/SDCCmain.c (main):
7561 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
7562 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
7563 The consequence was that some temporary files were not removed.
7566 unification of code in functions tempfilename() and tempfile():
7567 function tempnam() is defined in Visual Studio 6.0 and .NET
7569 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
7571 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
7572 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
7573 - removed compiler command line option /WX: Treats all warnings as errors
7574 - update a list of source files, included into the project
7576 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
7577 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
7578 changed project type to Generic Project so that can be correcly converted to VS.NET project
7580 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
7582 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
7584 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
7586 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
7587 added return 0 statements after assert() to make compiler happy
7589 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
7590 added newline in the def file to keep MSC compiler satisfied
7592 * sdcc/src/z80/gen.c:
7593 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
7594 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
7595 - solved MSC error in function aopDump()
7597 * sdcc_vc.h: define PREFIX as "\\sdcc"
7599 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
7600 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

7603 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
7604 - Rewrote the register banking algorithm.
7605 - Added pCode live-range analysis to registers (for now, only non-used and
7606 singly-used registers optimized away)
7608 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
7610 * 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.

7639 2002-03-28 Johan Knol <johan AT balder>
7641 * src/SDCCval.c: fixed bug #532436
7643 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7645 Added "char *Processor" field to the port structure.
7648 Added -p option. Allows port dependent processor to be specified.
7651 Initialized the new field char *Processor field to NULL in all ports
7654 Compiler generated registers for interrupt context saving
7655 were not getting allocated.
7657 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
7660 Fixed left shift. Will promote the left side of a left shift
7661 if a) left shifting more than size of operand or b) when assigned
7662 to something size > size of left side
7664 2002-03-14 Scott Dattalo <scott AT dattalo.com>
7666 tons of changes. Register allocation has been
7667 rewritten. Added customization for the various PICs. Flow
7668 analysis is restructured. ...
7674 Added. device.c is a PIC port hack to accomodate variations
7677 2002-03-13 Michael Hope <michaelh AT vroom>
7679 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.

7772 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
7774 * sdcc/src/SDCCloop.c:
7775 Previous fix was not good. basic blocks that have "break" or "return" are
7776 not really partof a loop , but live ranges used in these blocks should
7777 be live thru the entire loop, so set partOfLoop but don't add them to
7780 2002-02-21 <johan AT FRIJA>
7782 * src/SDCCcse.c: fixed bug #514308
7784 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
7787 Fixed BUG #519583. If a conditional block ended in a return/break
7788 statement inside a loop, it was not being considered part of the loop.
7790 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
7792 2002-02-10 Karl Bongers <karl AT turbobit.com>
7795 Fixed up SDCDB debugger somewhat. Updated debugger/README
7796 with lots of comments and notes.
7798 * device/examples/test2.c:
7799 Fix bug, "red" variable not being initialized(compiler complained).
7801 * device/examples/Makefile, examples/test3.c:
7802 Add Makefile in device/examples folder, compiles test3.c
7803 for use as a multiple module SDCDB test case.
7805 * sim/ucsim/cmd.src/cmdset.cc:
7806 Took out debug printfs in ucsim "next" command.
7809 Karl and Johan start ucsim XA support. Most dissassembly working,
7810 about 75% emulation done(plenty of work remaining).
7812 * sim/ucsim/z80.src:
7813 Add Z80 support to ucsim, add test-ucz80 regression test,
7814 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

7850 set preprocessor defines (depending on options)
7852 * src/SDCCicode.c, src/SDCCicode.h:
7853 changes made to handle multiple sends & receives
7856 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
