507 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
509 Enabled VPATH feature: changed nearly all Makefiles (149 files).
510 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
512 One basic decision: e.g. src/clean.mk includes further files. In order
513 to make this work there are two solutions:
514 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
515 run configure on them. This way they can use
516 'include $(srcdir)/port-clean.mk'
517 - always include clean.mk by the Makefile at the same level. To avoid
518 that `make clean` tries to include and build Makefile.dep the
519 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
520 implemented, because now even `make uninstall` doesn't create
521 Makefile.in. clean.mk could be eliminated by pasting it in
524 * debugger/mcs51/Makefile.in: build own objects from library sources
525 (SLIB, SDCC) in current directory
527 * configure, configure.in: renamed --disable-device-lib-build in
528 --disable-device-lib; added --enable-doc, the required tools are
529 searched by configure; added result message; the toolchain for the
530 belonging ports are now only built, if the port is enabled.
532 * support/regression/*: all output is written in directory gen, because
533 the fwk and ports directories don't livet in the build tree using vpath
535 * doc/sdccman.lyx: renamed --disable-device-lib-build to
536 --disable-device-lib, added --enable-doc, added section VPATH
538 * sim/ucsim/configure.in,
539 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
540 z80 are enabled by default
542 2006-04-24 Raphael Neider <rneider AT web.de>
544 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
545 to config word, "pic14_"-prefixed some extern functions

547 config word has been found
548 * src/pic/device.h: added prototypes

860 allocating functions mark all registers as free. This eliminates some
861 side effects resulting from peephole parser done earlier in the backbone

920 * src/pic16/gen.c (genPcall): fixed bug #1443644
921 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
922 which dumps before the function entry point a data byte which represents
923 the number of the local variables used by the specified function, added
924 'xinst' for initial support for Extended Instruction Support,
925 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
926 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
927 port->fun_prefix anymore (may change later),
928 (genFunction, genEndFunction): do not store/restore local registers for
929 _main (this should take care the --main-return command line option in
931 (genOr): removed some legacy pic-port instructions,
932 * src/pic16/genarith.c (genAddLit): re-enabled old code because
933 performing operations with SFR's causes data to be written more than
934 once to each SFR. Perhaps SFRs should be handled in special cases...
935 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
937 * src/pic16/main.c (_process_pragma): stack bound checking did not take
938 into account for stack starting position,
939 (struct OPTIONS pic16_optionsTable): added command line argument
940 --extended or -y for Extended Instruction Support,
941 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
942 (deassignLRs): *** perhaps the most important change, old 'for' code
943 (commented out for reference), didn't account for some registers which
944 were left marked 'not free' after a pointer operation. The change
945 reduces register usage a lot in some cases

3220 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3221 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3222 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3223 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3224 always available in leading double underscore form. The C99 support is
3225 mostly missing, but it's a start.
3226 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3227 reserved identifier "__data".

3305 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3307 * device/lib/printf_large.c: removed inline assembly for portability and
3308 readability. Use printf_fast if speed or size are more important.
3309 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3310 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3312 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3314 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3315 prevent compiler warning
3317 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3319 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3320 moved to level 0 and declared as static. Also they are explicit
3321 placed in access bank. This was necessery because some times they
3322 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3323 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3324 optimizations. Currently only compare to unsigned char is implemented,
3325 * src/pic16/gen.c: added fReturnIdx array,
3326 * (struct resolvedIfx) is moved to gen.h and made public,
3327 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3328 * (aopForSym): added an optimization to directly store in stack of
3329 the operand of a SEND iCode,
3330 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3331 but as registers instead (AOP_REG) using the fReturnIdx array,
3332 * (pic16_freeAsmop): remove the freed register from the
3333 _G.sregsAlloc field,
3334 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3335 a compare of 'WREG',
3336 * (pic16_popGetTempRegCond): changed function prototype, now
3337 function takes also a bitVector argument v which holds the current
3338 set of registers that are allocated for stack access by aopForSym,
3339 registers allocated in aopForSym for accessing stack symbols are not
3340 any more part of the functions usedRegs field,
3341 * (genCall): some times aopOp is called for a stack variable to be
3342 send, aopForSym might perform the push, if this is true make sure
3343 that genCall doesn't push the variable twice by testing _G.resDirect,
3344 * (genFunction): changed testing for unspecified interrupt number
3345 from 256 to INTNO_UNSPEC,
3346 * modified selection scheme of frame pointer generation. Previously
3347 if function did use local registers a frame pointer was generated,
3348 now a frame pointer is generated only if function has arguments
3349 (that need PLUSW2 register access), or has stack arguments, or the
3350 compiler is not instructed to omit the frame pointer,
3351 * (genEndFunction): before restoring local registers that were saved
3352 in the function preamble, also restore the registers that *might*
3353 have been allocated for stack access,
3354 * (genRet): removed some old comments,
3355 * (genCmp, the active (RN's) version): added a call to the
3356 pic16_genCmp_special function to perform the compare with a more
3357 robust and optimized way,
3358 * (genInline): a feature has been added in inline code generation,
3359 which allows a wildcard variable substitution when writing inline
3360 assembly. Code is incomplete and experimental therefore undocumented,
3361 * (genCast): changed order of aopOp for result and right to allow
3362 aopForSym to directly load the result if possible,
3363 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3364 perform an optimized compare on some selected special occasions,
3365 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3366 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3367 generate an IVT any more,
3368 * src/pic16/main.c (pic16_optionsTable): added command line option
3370 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3371 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3373 * src/pic16/NOTES: Raphael Neider added in list of active developers
3374 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3375 jumptable_end to prevent bug #,
3376 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3377 inCond and outCond fields,
3378 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3379 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3380 turn off register spilling,
3381 * (packRegsForOneUse): synced with other ports' versions although it
3382 is not used currently,
3383 * (pic16_packRegisters): added an optimization while reading
3384 structure bitfields, some registers may be saved (malloc code is
3385 decreased by 80 bytes)
3387 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3389 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3390 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3391 this can be optimized more?
3393 2005-03-10 Raphael Neider <rneider AT web.de>
3395 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3396 genNearPointerGet): (hopefully) fixed access to bitfields via
3397 pointers (p->bitN = x; and x = p->bitN; failed)
3399 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3440 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3442 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3443 to keep the correct label reference count when adding/removing references
3444 to labels. A peephole file using this is appended to patch #1144962.
3446 2005-02-14 Raphael Neider <rneider AT web.de>

4031 Adding support for replacing ljmps with sjmps in jumptables
4032 generated for switch statements. For now you need to set the
4033 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4034 Now 4 algorithms for mcs51 jumptable generation are used:
4035 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4036 addresses loaded pc-relative for up to 112 cases and stack-pushing
4037 target addresses loaded with offset from dptr for up to 256 cases.

4067 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4069 * added libc directory. The current version of LibC contains string
4070 functions, ctype functions and macros and some functions of the
4071 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4072 be extensively tested in the future. Standard disclaimer here.
4073 Library is not automatically build yet. But one can build it by
4074 invoking 'make' inside the libc directory.

4085 * (pic16_storeForReturn): optimized return of 0,
4086 * (genCmp): experimental code for new genCmp which uses PIC18's
4087 special compare&skip instructions. Initial tests fail some times
4088 with variables grater than 1 byte in size, so new code is disabled,
4089 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4091 * (genCast): began a fix to optimize the casting of a bit to another
4092 bit, now assigning a bitfield to another bitfield will fail, sorry,
4093 * src/pic16/main.c: disabled the use of lr-support feature,
4094 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4101 and 1 for banking instruction,
4102 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4103 caused stop processing pCodes after a inline assembly block,
4104 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4105 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4106 registers when it shouldn't,
4107 * src/pic16/ralloc.c (allocReg): add preliminary support for
4108 supporting a limited set of temporary registers,
4110 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4112 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4113 genDataPointerSet): ensure assignments always copy in MSB to LSB
4115 (loadRegFromAop): recognize CLRH optimization,
4116 (genFunction): optimize RECEIVE iCodes in reentrant functions
4118 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7118 loaded with the linker search paths (-L arguments) and the libraries
7119 to be linked with the current source (-l arguments). Changes
7120 currently will affect only the pic16 port.
7121 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7122 include path the port specific paths and port specific libraries,
7123 * gplink command now contains the $3 argument,
7124 * src/pic16/device.h,

7141 Documenting changes from previous commits.
7142 * configure.in (version 1.56),
7143 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7144 when generating output files to configure the pic16 library,
7145 but now I've commented it out, since gputils aren't installed in the
7146 SF compile farm, so library won't compile
7148 * device/lib/Makefile.in (version 1.56): initially I've added in
7149 target 'all' the prerequestive 'model-pic16' so it compiled the
7150 pic16 library, but now I've commented it out for the same reasons
7152 * added targets 'model-pic16' and 'objects-pic16' to compile the
7154 * added target 'port-specific-objects-pic16' to handle the
7155 generated libraries and copy them into the build/ directory
7156 * added target 'clean-intermediate-pic16' to clean intermediate
7157 files into pic16 directory
7158 * in target 'installdirs' added line to create directory pic16 in

7469 added pic16_printExterns to print extern symbols,
7470 pic16glue: initializes stack/frame pointer in the beginning of
7471 the assembly output. Temporary hack, will be corrected later,
7472 because gplink yet does not support stack and SDCC does not
7473 yet support a type of crt0.o object to create the final binary.
7475 * Removed many lines that contain 8051 legacy code.
7476 * The code is finally placed under a 'code' directive.
7477 * Added port specific options.
7479 * _process_pragma: simplified since now we do not need *special*
7480 include file to define SFR registers. But a separate header
7481 will be needed. This will be developed later.
7482 * _pic16_parseOptions: added, parses port specific options:
7483 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7484 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7485 --preplace-udata-with=
7487 * _pic16_setDefaultOptions: modified to initialize section names,
7488 but hack is temporarly out of order since it needs improvement.
7489 * _pic16_genAssemblerPreamble: configuration words are emitted by
7490 their address instead of their name. This part is incomplete and
7491 supports only the 18Fxx2 devices. Other devices will emit an error
7492 during assembly since they do not contain the same set of config
7494 * _pic16_genIVT: is modified,
7496 * pcode.c: added definitions for some hardware registers that are needed
7498 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7499 All PCI entries are updated. Now LFSR is supported.
7500 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7501 * added pic16_newpCodeOpLit2 to support instructions with
7502 two literal arguments
7503 * pic16_pCode2str: corrected code that emits assembler instructions
7504 with two literal operands and those that have an access bit modifier
7505 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7506 this fixes a bug which caused some labels to be lost, when an
7507 assembler directive was added, i.e. banksel,
7508 * pic16_FixRegisterBanking: improved logic that causes the insertion
7510 * InlineFunction: functions that are called once, are not any more
7511 inlined. This can be a port option in the future,
7513 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7515 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7516 hold the corresponding uninitialized symbols,
7517 * pic16_allocProcessorRegister: registers have explicit marked the
7519 * pic16_allocInternalRegister: registers are explicit marked as
7521 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7522 processing list, so bit registers were lost,
7525 * ralloc.h: added field 'accessBank' and original symbol operand
7526 in register definition,
7527 * removed the field isMapped from register definition,
7529 ** Several functions have been removed from various sources:
7530 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7531 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7532 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7533 pic16_assignRelocatableRegisters
7535 ** others have been introduced:
7536 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7537 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7539 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7541 * support/scripts/inc2h.pl: changed definition of BIT_AT
7542 to emit 'sbit at' instead of 'bit at'. This was a request.
7544 PIC16 port related preliminary changes:
7545 * gen.c: prefixed function popRegFromString with
7546 pic16_ and all references to it corrected
7547 * pcode.c: all pic16_pc_* hardware registers prefixed
7548 with underscore (_),
7549 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7550 * ralloc.c: newReg(): when register is REG_SFR then
7551 set address to rIdx,
7552 pic16_allocProcessorRegister(): marks register wasUsed=0
7553 pic16_writeUsedRegs(): added a call to assign processor
7554 registers via pic16_assignFixedRegisters
7556 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7558 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7559 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7560 variables in unused register banks. Also the SSEG is placed
7561 wherever there is enough space for it, and IDATA can be anywhere
7562 in internal RAM. For now compile using -Wl-Y[stack_size].
7563 The mem file is different for this option as well, since it
7564 makes no sense of talking about DSEG lenght.
7566 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7568 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7569 in certain cases, e.g. when ROM assignment, patch provided
7570 from Albert den Haan.

7811 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7813 * src/SDCCast.c (decorateType): disabled a transformation I added in
7814 revision 1.188 (access to fields of a structure at an absolute address);
7815 it breaks with bitfields, extern declarations, and gcse analysis.
7816 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7817 could be assigned through a pointer, so don't complain.
7818 * src/SDCCast.c (astErrors),
7820 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7922 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
7923 uninitialized variables) for the mcs51. Set environment variable
7924 SDCC_GENRAMCLEAR to test.
7925 xdata initialization slightly shorter
7927 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8575 fetching of the pointer
8576 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8577 copied from genNearPointerSet()
8578 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8579 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8595 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8596 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8597 type for bits was changed. It resulted in bit variables becoming
8598 global, which is not permitted in PIC 14 assembly output.
8600 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

8615 A few small changes that speed up the peephole optimizer.
8619 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8621 Try to make the peephole optimizer smarter by maintaining
8622 an association between the assembly source code and the
8623 iCodes that originated them. Put this information to use
8624 with a new peephole rule condition "notVolatile" so that
8625 the rules can be aggressive yet still safe.
8630 * src/mcs51/peeph.def
8632 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8636 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

8638 if the left or right operand symbols have the accuse flag set.
8640 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8642 Changed the type of the result of the ! (NOT) operator to char;
8643 previously it returned the same type as the source. This allows
8644 us to eliminate all the genFloatNot functions (all of its target
8645 implementations were very buggy) since !float can use the same

8658 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8659 during interrupts. Ensure WSAVE is located at a shared bank address.
8660 2. Fixed page selection in some places
8661 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8662 the registers name strings.
8663 4. Fixed "signed / unsigned compare" compiler warnings.
8664 5. The PIC port manages its own allocation of the general purpose
8665 registers, but makes no attempt to reuse them. As a result when
8666 compiling it soon runs out of general purpose registers. Some
8667 additional code was added to the files pcode.c and device.c to walk
8668 through the function call tree and rename the registers so that they
8678 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8685 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8687 Made bitfield a distinct type from bit so that bitfields
8688 convert as per ANSI C and bits retain their traditional
8689 boolean style behaviour. Implemented bitfield support in
8697 * src/ds390/gen.c: bit v bitfield split
8698 * src/z80/gen.c: New support for bitfields
8699 * support/regression/tests/bitfields.c: reenabled z80,
8702 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8704 Rules 246.x, 247.x relate to bitfields, the others speed up
8705 access to xdata mapped I/O devices.
8707 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8709 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8711 Cleaned up genPackBits and genUnpackBits and added two helper
8712 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8713 for literal assignments in genPackBits (thanks to Frieder for
8719 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8721 Fixed bug #748310 (pointer to function type mishandled when the
8722 function name is omitted). Also fixed a SIGSEGV when a function
8723 attribute (reentrant, etc) is used on a non-function or on a
8724 function but misplaced before the parameter list.
8726 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8728 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8729 * support/Util/SDCCerr.h,

8751 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8753 Made the constant following the "interrupt" keyword optional. If
8754 omitted, the function will not automatically be given an entry
8755 in the interrupt vector table (similar to #pragma NOIV, but
8756 less syntacticly kludgy). The interrupt number is also now
8757 range checked. Also fixed a bug in the high order bit example

8771 * src/SDCCicode.c (operandOperation): rewritten some ops
8772 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8773 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8775 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8776 be re-activated by defining REDUCE_LITERALS)
8777 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8778 unsigned, but are signed by default
8779 * src/SDCCval.c (constVal): rearranged
8780 * src/SDCCval.c (valMod): preliminary fix
8781 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9286 * src/SDCCmain.c: linkOptions is changed to set *,
9287 added if/endif conditional macros to remove options help
9288 messages from optionsTable when a port is not configured, added
9289 support for the PIc16 port in the ports table, when executing
9290 the compiler with no port specified on command line, a default
9291 port is selected with the new macro DEFAULT_PORT which is
9292 defined in port.h, in setDefaultOptions() linkOptions is removed
9293 from initialization assignment, since now it is a set,
9294 parseCmdLine uses setParseWithComma for linkOptions, in
9295 linkEdit() linkOptions are accessed with new function indexSet()
9296 which returns the i'th item of a set variable. See SDCCset.c, in
9297 linkEdit() when calling buildCmdLine(), added linkOptions as
9298 last argument. Now users can pass arguments to gplink via the
9299 -Wl option, main() uses pic16glue() to glue up pic16 programs

9311 * src/pic16/glue.c: commented out some error producing lines
9312 * src/pic16/main.c: __config directives are commented out to stop
9313 gpasm complaining and test the linkage with gplink, _linkCmd and
9314 _asmCmd changed to be more gplink and gpasm friendly
9315 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9316 produced an error when parsed, peep rule 12 is added to utilize
9317 movff, but it is commented out since the pCode does not support
9318 yet a command with 2 address arguments
9320 2003-05-18 <johan AT balder>
9322 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
9323 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9347 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9349 2003-05-11 Borut Razem <borut.razem AT siol.net>
9351 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9352 the path of bin directory, so that PATH is the only env. variable, which has to be set
9353 in case of standard installation.
9354 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10372 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10374 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10375 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10377 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10378 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10380 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10381 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10383 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10385 * in \sdcc\as\mcs51\ changed these files in order to create an
10386 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10387 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10388 following files to include the previous two files: aslink.dsp,
10389 Makefile.aslink, Makefile.bcc, and Makefile.in.
10391 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10392 .adb instead of .cdb
10394 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10396 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10397 value from option --iram-size.
10399 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10401 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10404 2002-09-18 <wiml AT hhhh.org>
10406 * SDCClrange.h: exposed setFromRange() and setToRange()
10407 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10408 packRegsForAccUse() (bug 542397)
10409 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10410 multiple times and emitting the fetch operations more than once
10411 added aopGetUsesAcc() function to allow binary operators to
10412 fetch their operands in the correct order; made genMinus() emit
10413 compact code for X = LITERAL - Y
10415 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10416 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10417 sprintf() in line 1267.
10419 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10420 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10423 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10424 Changes to aslink (All the changes are marked with 'JCF'):
10426 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10429 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10430 area BSEG. Also moves, if possible, the DATA area down into the internal
10431 ram so more space is available.
10433 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10436 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10437 not bytes. Function summary() which creates a memory usage summary
10438 file with extension .mem. Reports of overlaping stack and small stack
10439 size. If the space for the stack is less than 16 bytes aslink trows a
10442 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10443 the 8051. Option 'y' for memory summary output file.
10445 Changes to sdcc (All the changes are marked with 'JCF'):
10447 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10449 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10450 overlaying area for it (uses RegBankUsed[4]).
10452 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10453 bank zero as used by default. By default aslink locates the stack
10454 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10455 the creation of the .mem file. Delegates the allocation of data area
10456 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10457 the begining of the stack area to aslink.
10459 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10460 glue() in SDCCglue.c creates an area for it.
10462 2002-09-03 Borut Razem <borut.razem AT siol.net>
10463 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10464 sdcc/src/pic/glue.c:
10465 introduced atexit() handler for teporay files removal in case of
10466 errors, assertions, ...
10468 2002-08-29 Borut Razem <borut.razem AT siol.net>
10469 * sdcc/support/cpp2/auto-host_vc_in.h:
10470 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10471 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10472 Maybe there is a similar problem with BORLANDC? It should be checked!
10474 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10475 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10476 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10477 was not executed, and the compiler (cl) launched a warning:
10478 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10480 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10481 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10483 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10484 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10486 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10487 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10488 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10489 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10490 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10491 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10492 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10493 - added Release configuration in VS projects
10494 - review of compiler an linker options
10495 - VC .exe files are generated in bin_vc directory, not to interfere
10496 with binaries generated from other projects (cygwin, mingw, bcc ...)
10498 * sdcc/src/yacc.dsp: added
10500 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10501 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10502 and insert the version number definitions from .version
10504 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10506 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10507 added - genarate auto-host.h using auto-host_vc_in.h as template
10510 removed from CVS, generated automatically
10512 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10513 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10515 2002-08-11 Borut Razem <borut.razem AT siol.net>
10516 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10518 2002-08-10 Borut Razem <borut.razem AT siol.net>
10519 * src/SDCCmain.c (main):
10520 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10521 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10522 The consequence was that some temporary files were not removed.
10525 unification of code in functions tempfilename() and tempfile():
10526 function tempnam() is defined in Visual Studio 6.0 and .NET
10528 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10530 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10531 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10532 - removed compiler command line option /WX: Treats all warnings as errors
10533 - update a list of source files, included into the project
10535 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10536 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10537 changed project type to Generic Project so that can be correcly converted to VS.NET project
10539 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10541 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10543 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10545 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10546 added return 0 statements after assert() to make compiler happy
10548 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10549 added newline in the def file to keep MSC compiler satisfied
10551 * sdcc/src/z80/gen.c:
10552 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10553 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10554 - solved MSC error in function aopDump()
10556 * sdcc_vc.h: define PREFIX as "\\sdcc"
10558 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10559 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
10561 2002-06-22 Scott Dattalo <scott AT dattalo.com>
10562 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10563 - Rewrote the register banking algorithm.
10564 - Added pCode live-range analysis to registers (for now, only non-used and
10565 singly-used registers optimized away)
10567 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10569 * 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.

10594 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10596 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10598 2002-03-28 Johan Knol <johan AT balder>
10600 * src/SDCCval.c: fixed bug #532436
10602 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10604 Added "char *Processor" field to the port structure.
10607 Added -p option. Allows port dependent processor to be specified.
10610 Initialized the new field char *Processor field to NULL in all ports
10613 Compiler generated registers for interrupt context saving
10614 were not getting allocated.
10616 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10619 Fixed left shift. Will promote the left side of a left shift
10620 if a) left shifting more than size of operand or b) when assigned
10621 to something size > size of left side
10623 2002-03-14 Scott Dattalo <scott AT dattalo.com>

10627 analysis is restructured. ...
10629 * src/pic/device.h:
10632 * src/pic/device.c:
10633 Added. device.c is a PIC port hack to accomodate variations
10636 2002-03-13 Michael Hope <michaelh AT vroom>
10638 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10640 2002-03-04 johanknol <johanknol AT manik>
10642 * /src/SDCCval.c: fixed
10644 const unsigned char arr[][2] = { { 0, 1 } };

10731 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10733 * sdcc/src/SDCCloop.c:
10734 Previous fix was not good. basic blocks that have "break" or "return" are
10735 not really partof a loop , but live ranges used in these blocks should
10736 be live thru the entire loop, so set partOfLoop but don't add them to
10739 2002-02-21 <johan AT FRIJA>
10741 * src/SDCCcse.c: fixed bug #514308
10743 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10746 Fixed BUG #519583. If a conditional block ended in a return/break
10747 statement inside a loop, it was not being considered part of the loop.
10749 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10751 2002-02-10 Karl Bongers <karl AT turbobit.com>
