524 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
526 Enabled VPATH feature: changed nearly all Makefiles (149 files).
527 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
529 One basic decision: e.g. src/clean.mk includes further files. In order
530 to make this work there are two solutions:
531 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
532 run configure on them. This way they can use
533 'include $(srcdir)/port-clean.mk'
534 - always include clean.mk by the Makefile at the same level. To avoid
535 that `make clean` tries to include and build Makefile.dep the
536 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
537 implemented, because now even `make uninstall` doesn't create
538 Makefile.in. clean.mk could be eliminated by pasting it in
541 * debugger/mcs51/Makefile.in: build own objects from library sources
542 (SLIB, SDCC) in current directory
544 * configure, configure.in: renamed --disable-device-lib-build in
545 --disable-device-lib; added --enable-doc, the required tools are
546 searched by configure; added result message; the toolchain for the
547 belonging ports are now only built, if the port is enabled.
549 * support/regression/*: all output is written in directory gen, because
550 the fwk and ports directories don't livet in the build tree using vpath
552 * doc/sdccman.lyx: renamed --disable-device-lib-build to
553 --disable-device-lib, added --enable-doc, added section VPATH
555 * sim/ucsim/configure.in,
556 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
557 z80 are enabled by default
559 2006-04-24 Raphael Neider <rneider AT web.de>
561 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
562 to config word, "pic14_"-prefixed some extern functions
563 (pic14_emitConfigWord): emit __config directive(s) if assignment to
564 config word has been found
565 * src/pic/device.h: added prototypes
566 * src/pic/pcode.c: added "pic14_"-prefix where needed
567 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
569 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

875 call to allocReg, not by manually allocating a new one,
876 (pic16_assignRegisters): now before going through the register
877 allocating functions mark all registers as free. This eliminates some
878 side effects resulting from peephole parser done earlier in the backbone

926 * device/include/mcs51/c8051f410.h: new SiLabs mcu
927 * src/ds390/peeph.def: disabled 186.d and 227.a as fix for #1434401
928 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
930 2006-03-06 Borut Razem <borut.razem AT siol.net>
932 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
933 made the linker quiet
935 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
937 * src/pic16/gen.c (genPcall): fixed bug #1443644
938 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
939 which dumps before the function entry point a data byte which represents
940 the number of the local variables used by the specified function, added
941 'xinst' for initial support for Extended Instruction Support,
942 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
943 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
944 port->fun_prefix anymore (may change later),
945 (genFunction, genEndFunction): do not store/restore local registers for
946 _main (this should take care the --main-return command line option in
948 (genOr): removed some legacy pic-port instructions,
949 * src/pic16/genarith.c (genAddLit): re-enabled old code because
950 performing operations with SFR's causes data to be written more than
951 once to each SFR. Perhaps SFRs should be handled in special cases...
952 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
954 * src/pic16/main.c (_process_pragma): stack bound checking did not take
955 into account for stack starting position,
956 (struct OPTIONS pic16_optionsTable): added command line argument
957 --extended or -y for Extended Instruction Support,
958 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
959 (deassignLRs): *** perhaps the most important change, old 'for' code
960 (commented out for reference), didn't account for some registers which
961 were left marked 'not free' after a pointer operation. The change
962 reduces register usage a lot in some cases

3235 * src/SDCCglobal.h (struct options),
3237 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3238 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3239 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3240 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3241 always available in leading double underscore form. The C99 support is
3242 mostly missing, but it's a start.

3322 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3324 * device/lib/printf_large.c: removed inline assembly for portability and
3325 readability. Use printf_fast if speed or size are more important.
3326 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3327 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3329 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3331 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3332 prevent compiler warning
3334 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3336 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3337 moved to level 0 and declared as static. Also they are explicit
3338 placed in access bank. This was necessery because some times they
3339 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3340 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3341 optimizations. Currently only compare to unsigned char is implemented,
3342 * src/pic16/gen.c: added fReturnIdx array,
3343 * (struct resolvedIfx) is moved to gen.h and made public,
3344 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3345 * (aopForSym): added an optimization to directly store in stack of
3346 the operand of a SEND iCode,
3347 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3348 but as registers instead (AOP_REG) using the fReturnIdx array,
3349 * (pic16_freeAsmop): remove the freed register from the
3350 _G.sregsAlloc field,
3351 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3352 a compare of 'WREG',
3353 * (pic16_popGetTempRegCond): changed function prototype, now
3354 function takes also a bitVector argument v which holds the current
3355 set of registers that are allocated for stack access by aopForSym,
3356 registers allocated in aopForSym for accessing stack symbols are not
3357 any more part of the functions usedRegs field,
3358 * (genCall): some times aopOp is called for a stack variable to be
3359 send, aopForSym might perform the push, if this is true make sure
3360 that genCall doesn't push the variable twice by testing _G.resDirect,
3361 * (genFunction): changed testing for unspecified interrupt number
3362 from 256 to INTNO_UNSPEC,
3363 * modified selection scheme of frame pointer generation. Previously
3364 if function did use local registers a frame pointer was generated,
3365 now a frame pointer is generated only if function has arguments
3366 (that need PLUSW2 register access), or has stack arguments, or the
3367 compiler is not instructed to omit the frame pointer,
3368 * (genEndFunction): before restoring local registers that were saved
3369 in the function preamble, also restore the registers that *might*
3370 have been allocated for stack access,
3371 * (genRet): removed some old comments,
3372 * (genCmp, the active (RN's) version): added a call to the
3373 pic16_genCmp_special function to perform the compare with a more
3374 robust and optimized way,
3375 * (genInline): a feature has been added in inline code generation,
3376 which allows a wildcard variable substitution when writing inline
3377 assembly. Code is incomplete and experimental therefore undocumented,
3378 * (genCast): changed order of aopOp for result and right to allow
3379 aopForSym to directly load the result if possible,
3380 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3381 perform an optimized compare on some selected special occasions,
3382 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3383 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3384 generate an IVT any more,
3385 * src/pic16/main.c (pic16_optionsTable): added command line option
3387 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3388 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3390 * src/pic16/NOTES: Raphael Neider added in list of active developers
3391 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3392 jumptable_end to prevent bug #,
3393 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3394 inCond and outCond fields,
3395 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3396 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3397 turn off register spilling,
3398 * (packRegsForOneUse): synced with other ports' versions although it
3399 is not used currently,
3400 * (pic16_packRegisters): added an optimization while reading
3401 structure bitfields, some registers may be saved (malloc code is
3402 decreased by 80 bytes)
3404 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3406 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3407 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3408 this can be optimized more?
3410 2005-03-10 Raphael Neider <rneider AT web.de>
3412 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3413 genNearPointerGet): (hopefully) fixed access to bitfields via
3414 pointers (p->bitN = x; and x = p->bitN; failed)
3416 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3418 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4048 Adding support for replacing ljmps with sjmps in jumptables
4049 generated for switch statements. For now you need to set the
4050 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4051 Now 4 algorithms for mcs51 jumptable generation are used:
4052 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4053 addresses loaded pc-relative for up to 112 cases and stack-pushing
4054 target addresses loaded with offset from dptr for up to 256 cases.

4080 Large cummulative patch for pic16 port.
4081 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
4082 to call when a stack overflow occurs,
4083 * (malloc.h): added CVS Id tag,
4084 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4086 * added libc directory. The current version of LibC contains string
4087 functions, ctype functions and macros and some functions of the
4088 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4089 be extensively tested in the future. Standard disclaimer here.
4090 Library is not automatically build yet. But one can build it by
4091 invoking 'make' inside the libc directory.
4092 * added ADC library under libio. Preliminary version yet.

4098 temporary registers, its a buggy feature and will be removed,
4099 * (pic16_popGet): set register instance field in AOP_CRY,

4102 * (pic16_storeForReturn): optimized return of 0,
4103 * (genCmp): experimental code for new genCmp which uses PIC18's
4104 special compare&skip instructions. Initial tests fail some times
4105 with variables grater than 1 byte in size, so new code is disabled,
4106 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4108 * (genCast): began a fix to optimize the casting of a bit to another
4109 bit, now assigning a bitfield to another bitfield will fail, sorry,
4110 * src/pic16/main.c: disabled the use of lr-support feature,
4111 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,
4112 * added some function prototypes, added function _debugf prototype,

4114 bits with offset (case PO_GPR_BIT),
4115 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4117 * (isBankInstruction): modified to return 0 for no banking instruction,
4118 and 1 for banking instruction,
4119 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4120 caused stop processing pCodes after a inline assembly block,
4121 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4122 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4123 registers when it shouldn't,
4124 * src/pic16/ralloc.c (allocReg): add preliminary support for
4125 supporting a limited set of temporary registers,
4127 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4129 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4130 genDataPointerSet): ensure assignments always copy in MSB to LSB
4132 (loadRegFromAop): recognize CLRH optimization,
4133 (genFunction): optimize RECEIVE iCodes in reentrant functions
4135 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4137 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with
4138 --out-fmt-s19 turning into --out-fmt-elf if s19 was already

7134 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7135 loaded with the linker search paths (-L arguments) and the libraries
7136 to be linked with the current source (-l arguments). Changes
7137 currently will affect only the pic16 port.
7138 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7139 include path the port specific paths and port specific libraries,
7140 * gplink command now contains the $3 argument,
7141 * src/pic16/device.h,

7158 Documenting changes from previous commits.
7159 * configure.in (version 1.56),
7160 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7161 when generating output files to configure the pic16 library,
7162 but now I've commented it out, since gputils aren't installed in the
7163 SF compile farm, so library won't compile
7165 * device/lib/Makefile.in (version 1.56): initially I've added in
7166 target 'all' the prerequestive 'model-pic16' so it compiled the
7167 pic16 library, but now I've commented it out for the same reasons
7169 * added targets 'model-pic16' and 'objects-pic16' to compile the
7171 * added target 'port-specific-objects-pic16' to handle the
7172 generated libraries and copy them into the build/ directory
7173 * added target 'clean-intermediate-pic16' to clean intermediate
7174 files into pic16 directory
7175 * in target 'installdirs' added line to create directory pic16 in

7474 genFunction,genEndFunction: setup stack frame for the
7476 genAddrOf: will be changed according to bug 863624
7478 * added files genutils.c and genutils.h which contain gen*
7479 debugged and optimised functions extracted from gen.c
7481 * glue.c: added variable 'externs' which holds extern symbols,
7482 pic16emitRegularMap: is modified to properly handle relocatable
7483 symbols under the new scheme,
7484 pic16createInterruptVect: is modified
7485 pic16printPublics: is modified to emit 'global' assembler directives,
7486 added pic16_printExterns to print extern symbols,
7487 pic16glue: initializes stack/frame pointer in the beginning of
7488 the assembly output. Temporary hack, will be corrected later,
7489 because gplink yet does not support stack and SDCC does not
7490 yet support a type of crt0.o object to create the final binary.
7492 * Removed many lines that contain 8051 legacy code.
7493 * The code is finally placed under a 'code' directive.
7494 * Added port specific options.
7496 * _process_pragma: simplified since now we do not need *special*
7497 include file to define SFR registers. But a separate header
7498 will be needed. This will be developed later.
7499 * _pic16_parseOptions: added, parses port specific options:
7500 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7501 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7502 --preplace-udata-with=
7504 * _pic16_setDefaultOptions: modified to initialize section names,
7505 but hack is temporarly out of order since it needs improvement.
7506 * _pic16_genAssemblerPreamble: configuration words are emitted by
7507 their address instead of their name. This part is incomplete and
7508 supports only the 18Fxx2 devices. Other devices will emit an error
7509 during assembly since they do not contain the same set of config
7511 * _pic16_genIVT: is modified,
7513 * pcode.c: added definitions for some hardware registers that are needed
7515 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7516 All PCI entries are updated. Now LFSR is supported.
7517 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7518 * added pic16_newpCodeOpLit2 to support instructions with
7519 two literal arguments
7520 * pic16_pCode2str: corrected code that emits assembler instructions
7521 with two literal operands and those that have an access bit modifier
7522 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7523 this fixes a bug which caused some labels to be lost, when an
7524 assembler directive was added, i.e. banksel,
7525 * pic16_FixRegisterBanking: improved logic that causes the insertion
7527 * InlineFunction: functions that are called once, are not any more
7528 inlined. This can be a port option in the future,
7530 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7532 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7533 hold the corresponding uninitialized symbols,
7534 * pic16_allocProcessorRegister: registers have explicit marked the
7536 * pic16_allocInternalRegister: registers are explicit marked as
7538 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7539 processing list, so bit registers were lost,
7542 * ralloc.h: added field 'accessBank' and original symbol operand
7543 in register definition,
7544 * removed the field isMapped from register definition,
7546 ** Several functions have been removed from various sources:
7547 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7548 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7549 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7550 pic16_assignRelocatableRegisters
7552 ** others have been introduced:
7553 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7554 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7556 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7558 * support/scripts/inc2h.pl: changed definition of BIT_AT
7559 to emit 'sbit at' instead of 'bit at'. This was a request.
7561 PIC16 port related preliminary changes:
7562 * gen.c: prefixed function popRegFromString with
7563 pic16_ and all references to it corrected
7564 * pcode.c: all pic16_pc_* hardware registers prefixed
7565 with underscore (_),
7566 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7567 * ralloc.c: newReg(): when register is REG_SFR then
7568 set address to rIdx,
7569 pic16_allocProcessorRegister(): marks register wasUsed=0
7570 pic16_writeUsedRegs(): added a call to assign processor
7571 registers via pic16_assignFixedRegisters
7573 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7575 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7576 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7577 variables in unused register banks. Also the SSEG is placed
7578 wherever there is enough space for it, and IDATA can be anywhere
7579 in internal RAM. For now compile using -Wl-Y[stack_size].
7580 The mem file is different for this option as well, since it
7581 makes no sense of talking about DSEG lenght.
7583 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7585 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7586 in certain cases, e.g. when ROM assignment, patch provided
7587 from Albert den Haan.

7828 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7830 * src/SDCCast.c (decorateType): disabled a transformation I added in
7831 revision 1.188 (access to fields of a structure at an absolute address);
7832 it breaks with bitfields, extern declarations, and gcse analysis.
7833 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7834 could be assigned through a pointer, so don't complain.
7835 * src/SDCCast.c (astErrors),
7837 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8591 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8592 fetching of the pointer
8593 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8594 copied from genNearPointerSet()
8595 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8596 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8612 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8613 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8614 type for bits was changed. It resulted in bit variables becoming
8615 global, which is not permitted in PIC 14 assembly output.
8617 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8619 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8632 A few small changes that speed up the peephole optimizer.
8636 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8638 Try to make the peephole optimizer smarter by maintaining
8639 an association between the assembly source code and the
8640 iCodes that originated them. Put this information to use
8641 with a new peephole rule condition "notVolatile" so that
8642 the rules can be aggressive yet still safe.
8647 * src/mcs51/peeph.def
8649 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8653 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8654 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8655 if the left or right operand symbols have the accuse flag set.
8657 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8659 Changed the type of the result of the ! (NOT) operator to char;
8660 previously it returned the same type as the source. This allows
8661 us to eliminate all the genFloatNot functions (all of its target
8662 implementations were very buggy) since !float can use the same

8674 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8675 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8676 during interrupts. Ensure WSAVE is located at a shared bank address.
8677 2. Fixed page selection in some places
8678 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8679 the registers name strings.
8680 4. Fixed "signed / unsigned compare" compiler warnings.
8681 5. The PIC port manages its own allocation of the general purpose
8682 registers, but makes no attempt to reuse them. As a result when
8683 compiling it soon runs out of general purpose registers. Some
8684 additional code was added to the files pcode.c and device.c to walk
8685 through the function call tree and rename the registers so that they
8695 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8702 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8704 Made bitfield a distinct type from bit so that bitfields
8705 convert as per ANSI C and bits retain their traditional
8706 boolean style behaviour. Implemented bitfield support in
8714 * src/ds390/gen.c: bit v bitfield split
8715 * src/z80/gen.c: New support for bitfields
8716 * support/regression/tests/bitfields.c: reenabled z80,
8719 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8721 Rules 246.x, 247.x relate to bitfields, the others speed up
8722 access to xdata mapped I/O devices.
8724 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8726 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8728 Cleaned up genPackBits and genUnpackBits and added two helper
8729 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8730 for literal assignments in genPackBits (thanks to Frieder for
8736 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8738 Fixed bug #748310 (pointer to function type mishandled when the
8739 function name is omitted). Also fixed a SIGSEGV when a function
8740 attribute (reentrant, etc) is used on a non-function or on a
8741 function but misplaced before the parameter list.
8743 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8745 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8746 * support/Util/SDCCerr.h,
8747 * support/Util/SDCCerr.c: Added func attr misuse error msg

8768 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8770 Made the constant following the "interrupt" keyword optional. If
8771 omitted, the function will not automatically be given an entry
8772 in the interrupt vector table (similar to #pragma NOIV, but
8773 less syntacticly kludgy). The interrupt number is also now
8774 range checked. Also fixed a bug in the high order bit example

8788 * src/SDCCicode.c (operandOperation): rewritten some ops
8789 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8790 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8792 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8793 be re-activated by defining REDUCE_LITERALS)
8794 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8795 unsigned, but are signed by default
8796 * src/SDCCval.c (constVal): rearranged
8797 * src/SDCCval.c (valMod): preliminary fix
8798 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8840 constants are unsigned; added recognition of "u" flag for unsigned
8841 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8842 * src/SDCCval.c (valDiv, valMod): fixed signdness
8843 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8844 signedness of modulo, left and right shift

9303 * src/SDCCmain.c: linkOptions is changed to set *,
9304 added if/endif conditional macros to remove options help
9305 messages from optionsTable when a port is not configured, added
9306 support for the PIc16 port in the ports table, when executing
9307 the compiler with no port specified on command line, a default
9308 port is selected with the new macro DEFAULT_PORT which is
9309 defined in port.h, in setDefaultOptions() linkOptions is removed
9310 from initialization assignment, since now it is a set,
9311 parseCmdLine uses setParseWithComma for linkOptions, in
9312 linkEdit() linkOptions are accessed with new function indexSet()
9313 which returns the i'th item of a set variable. See SDCCset.c, in
9314 linkEdit() when calling buildCmdLine(), added linkOptions as
9315 last argument. Now users can pass arguments to gplink via the
9316 -Wl option, main() uses pic16glue() to glue up pic16 programs

9328 * src/pic16/glue.c: commented out some error producing lines
9329 * src/pic16/main.c: __config directives are commented out to stop
9330 gpasm complaining and test the linkage with gplink, _linkCmd and
9331 _asmCmd changed to be more gplink and gpasm friendly
9332 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9333 produced an error when parsed, peep rule 12 is added to utilize
9334 movff, but it is commented out since the pCode does not support
9335 yet a command with 2 address arguments
9337 2003-05-18 <johan AT balder>
9339 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9364 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9366 2003-05-11 Borut Razem <borut.razem AT siol.net>
9368 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9369 the path of bin directory, so that PATH is the only env. variable, which has to be set
9370 in case of standard installation.
9371 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10385 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10387 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10388 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10389 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10391 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10392 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10394 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10395 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10397 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10398 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10400 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10402 * in \sdcc\as\mcs51\ changed these files in order to create an
10403 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10404 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10405 following files to include the previous two files: aslink.dsp,
10406 Makefile.aslink, Makefile.bcc, and Makefile.in.
10408 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10409 .adb instead of .cdb
10411 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10413 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10414 value from option --iram-size.
10416 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10418 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10421 2002-09-18 <wiml AT hhhh.org>
10423 * SDCClrange.h: exposed setFromRange() and setToRange()
10424 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10425 packRegsForAccUse() (bug 542397)
10426 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10427 multiple times and emitting the fetch operations more than once
10428 added aopGetUsesAcc() function to allow binary operators to
10429 fetch their operands in the correct order; made genMinus() emit
10430 compact code for X = LITERAL - Y
10432 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10433 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10434 sprintf() in line 1267.
10436 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10437 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10440 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10441 Changes to aslink (All the changes are marked with 'JCF'):
10443 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10446 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10447 area BSEG. Also moves, if possible, the DATA area down into the internal
10448 ram so more space is available.
10450 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10453 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10454 not bytes. Function summary() which creates a memory usage summary
10455 file with extension .mem. Reports of overlaping stack and small stack
10456 size. If the space for the stack is less than 16 bytes aslink trows a
10459 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10460 the 8051. Option 'y' for memory summary output file.
10462 Changes to sdcc (All the changes are marked with 'JCF'):
10464 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10466 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10467 overlaying area for it (uses RegBankUsed[4]).
10469 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10470 bank zero as used by default. By default aslink locates the stack
10471 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10472 the creation of the .mem file. Delegates the allocation of data area
10473 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10474 the begining of the stack area to aslink.
10476 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10477 glue() in SDCCglue.c creates an area for it.
10479 2002-09-03 Borut Razem <borut.razem AT siol.net>
10480 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10481 sdcc/src/pic/glue.c:
10482 introduced atexit() handler for teporay files removal in case of
10483 errors, assertions, ...
10485 2002-08-29 Borut Razem <borut.razem AT siol.net>
10486 * sdcc/support/cpp2/auto-host_vc_in.h:
10487 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10488 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10489 Maybe there is a similar problem with BORLANDC? It should be checked!
10491 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10492 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10493 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10494 was not executed, and the compiler (cl) launched a warning:
10495 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10497 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10498 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10500 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10501 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10503 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10504 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10505 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10506 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10507 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10508 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10509 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10510 - added Release configuration in VS projects
10511 - review of compiler an linker options
10512 - VC .exe files are generated in bin_vc directory, not to interfere
10513 with binaries generated from other projects (cygwin, mingw, bcc ...)
10515 * sdcc/src/yacc.dsp: added
10517 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10518 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10519 and insert the version number definitions from .version
10521 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10523 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10524 added - genarate auto-host.h using auto-host_vc_in.h as template
10527 removed from CVS, generated automatically
10529 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10530 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10532 2002-08-11 Borut Razem <borut.razem AT siol.net>
10533 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10535 2002-08-10 Borut Razem <borut.razem AT siol.net>
10536 * src/SDCCmain.c (main):
10537 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10538 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10539 The consequence was that some temporary files were not removed.
10542 unification of code in functions tempfilename() and tempfile():
10543 function tempnam() is defined in Visual Studio 6.0 and .NET
10545 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10547 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10548 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10549 - removed compiler command line option /WX: Treats all warnings as errors
10550 - update a list of source files, included into the project
10552 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10553 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10554 changed project type to Generic Project so that can be correcly converted to VS.NET project
10556 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10558 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10560 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10562 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10563 added return 0 statements after assert() to make compiler happy
10565 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10566 added newline in the def file to keep MSC compiler satisfied
10568 * sdcc/src/z80/gen.c:
10569 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10570 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10571 - solved MSC error in function aopDump()
10573 * sdcc_vc.h: define PREFIX as "\\sdcc"
10575 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10576 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10579 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10580 - Rewrote the register banking algorithm.
10581 - Added pCode live-range analysis to registers (for now, only non-used and
10582 singly-used registers optimized away)
10584 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10586 * 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.

10611 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10613 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10615 2002-03-28 Johan Knol <johan AT balder>
10617 * src/SDCCval.c: fixed bug #532436
10619 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10621 Added "char *Processor" field to the port structure.
10624 Added -p option. Allows port dependent processor to be specified.
10627 Initialized the new field char *Processor field to NULL in all ports
10630 Compiler generated registers for interrupt context saving
10631 were not getting allocated.
10633 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10636 Fixed left shift. Will promote the left side of a left shift
10637 if a) left shifting more than size of operand or b) when assigned
10638 to something size > size of left side
10640 2002-03-14 Scott Dattalo <scott AT dattalo.com>

10644 analysis is restructured. ...
10646 * src/pic/device.h:
10649 * src/pic/device.c:
10650 Added. device.c is a PIC port hack to accomodate variations
10653 2002-03-13 Michael Hope <michaelh AT vroom>
10655 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10657 2002-03-04 johanknol <johanknol AT manik>
10659 * /src/SDCCval.c: fixed

10748 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10750 * sdcc/src/SDCCloop.c:
10751 Previous fix was not good. basic blocks that have "break" or "return" are
10752 not really partof a loop , but live ranges used in these blocks should
10753 be live thru the entire loop, so set partOfLoop but don't add them to
10756 2002-02-21 <johan AT FRIJA>
10758 * src/SDCCcse.c: fixed bug #514308
10760 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10763 Fixed BUG #519583. If a conditional block ended in a return/break
