520 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
522 Enabled VPATH feature: changed nearly all Makefiles (149 files).
523 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
525 One basic decision: e.g. src/clean.mk includes further files. In order
526 to make this work there are two solutions:
527 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
528 run configure on them. This way they can use
529 'include $(srcdir)/port-clean.mk'
530 - always include clean.mk by the Makefile at the same level. To avoid
531 that `make clean` tries to include and build Makefile.dep the
532 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
533 implemented, because now even `make uninstall` doesn't create
534 Makefile.in. clean.mk could be eliminated by pasting it in
537 * debugger/mcs51/Makefile.in: build own objects from library sources
538 (SLIB, SDCC) in current directory
540 * configure, configure.in: renamed --disable-device-lib-build in
541 --disable-device-lib; added --enable-doc, the required tools are
542 searched by configure; added result message; the toolchain for the
543 belonging ports are now only built, if the port is enabled.
545 * support/regression/*: all output is written in directory gen, because
546 the fwk and ports directories don't livet in the build tree using vpath
548 * doc/sdccman.lyx: renamed --disable-device-lib-build to
549 --disable-device-lib, added --enable-doc, added section VPATH
551 * sim/ucsim/configure.in,
552 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
553 z80 are enabled by default
555 2006-04-24 Raphael Neider <rneider AT web.de>
557 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
558 to config word, "pic14_"-prefixed some extern functions
559 (pic14_emitConfigWord): emit __config directive(s) if assignment to
560 config word has been found
561 * src/pic/device.h: added prototypes
562 * src/pic/pcode.c: added "pic14_"-prefix where needed

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

922 * device/include/mcs51/c8051f410.h: new SiLabs mcu
923 * src/ds390/peeph.def: disabled 186.d and 227.a as fix for #1434401
924 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
926 2006-03-06 Borut Razem <borut.razem AT siol.net>
928 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
929 made the linker quiet
931 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
933 * src/pic16/gen.c (genPcall): fixed bug #1443644
934 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
935 which dumps before the function entry point a data byte which represents
936 the number of the local variables used by the specified function, added
937 'xinst' for initial support for Extended Instruction Support,
938 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
939 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
940 port->fun_prefix anymore (may change later),
941 (genFunction, genEndFunction): do not store/restore local registers for
942 _main (this should take care the --main-return command line option in
944 (genOr): removed some legacy pic-port instructions,
945 * src/pic16/genarith.c (genAddLit): re-enabled old code because
946 performing operations with SFR's causes data to be written more than
947 once to each SFR. Perhaps SFRs should be handled in special cases...
948 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
950 * src/pic16/main.c (_process_pragma): stack bound checking did not take
951 into account for stack starting position,
952 (struct OPTIONS pic16_optionsTable): added command line argument
953 --extended or -y for Extended Instruction Support,
954 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
955 (deassignLRs): *** perhaps the most important change, old 'for' code
956 (commented out for reference), didn't account for some registers which
957 were left marked 'not free' after a pointer operation. The change
958 reduces register usage a lot in some cases

3231 * src/SDCCglobal.h (struct options),
3233 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3234 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3235 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3236 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3237 always available in leading double underscore form. The C99 support is
3238 mostly missing, but it's a start.

3318 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3320 * device/lib/printf_large.c: removed inline assembly for portability and
3321 readability. Use printf_fast if speed or size are more important.
3322 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3323 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3325 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3327 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3328 prevent compiler warning
3330 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3332 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3333 moved to level 0 and declared as static. Also they are explicit
3334 placed in access bank. This was necessery because some times they
3335 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3336 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3337 optimizations. Currently only compare to unsigned char is implemented,
3338 * src/pic16/gen.c: added fReturnIdx array,
3339 * (struct resolvedIfx) is moved to gen.h and made public,
3340 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3341 * (aopForSym): added an optimization to directly store in stack of
3342 the operand of a SEND iCode,
3343 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3344 but as registers instead (AOP_REG) using the fReturnIdx array,
3345 * (pic16_freeAsmop): remove the freed register from the
3346 _G.sregsAlloc field,
3347 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3348 a compare of 'WREG',
3349 * (pic16_popGetTempRegCond): changed function prototype, now
3350 function takes also a bitVector argument v which holds the current
3351 set of registers that are allocated for stack access by aopForSym,
3352 registers allocated in aopForSym for accessing stack symbols are not
3353 any more part of the functions usedRegs field,
3354 * (genCall): some times aopOp is called for a stack variable to be
3355 send, aopForSym might perform the push, if this is true make sure
3356 that genCall doesn't push the variable twice by testing _G.resDirect,
3357 * (genFunction): changed testing for unspecified interrupt number
3358 from 256 to INTNO_UNSPEC,
3359 * modified selection scheme of frame pointer generation. Previously
3360 if function did use local registers a frame pointer was generated,
3361 now a frame pointer is generated only if function has arguments
3362 (that need PLUSW2 register access), or has stack arguments, or the
3363 compiler is not instructed to omit the frame pointer,
3364 * (genEndFunction): before restoring local registers that were saved
3365 in the function preamble, also restore the registers that *might*
3366 have been allocated for stack access,
3367 * (genRet): removed some old comments,
3368 * (genCmp, the active (RN's) version): added a call to the
3369 pic16_genCmp_special function to perform the compare with a more
3370 robust and optimized way,
3371 * (genInline): a feature has been added in inline code generation,
3372 which allows a wildcard variable substitution when writing inline
3373 assembly. Code is incomplete and experimental therefore undocumented,
3374 * (genCast): changed order of aopOp for result and right to allow
3375 aopForSym to directly load the result if possible,
3376 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3377 perform an optimized compare on some selected special occasions,
3378 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3379 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3380 generate an IVT any more,
3381 * src/pic16/main.c (pic16_optionsTable): added command line option
3383 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3384 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3386 * src/pic16/NOTES: Raphael Neider added in list of active developers
3387 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3388 jumptable_end to prevent bug #,
3389 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3390 inCond and outCond fields,
3391 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3392 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3393 turn off register spilling,
3394 * (packRegsForOneUse): synced with other ports' versions although it
3395 is not used currently,
3396 * (pic16_packRegisters): added an optimization while reading
3397 structure bitfields, some registers may be saved (malloc code is
3398 decreased by 80 bytes)
3400 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3402 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3403 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3404 this can be optimized more?
3406 2005-03-10 Raphael Neider <rneider AT web.de>
3408 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3409 genNearPointerGet): (hopefully) fixed access to bitfields via
3410 pointers (p->bitN = x; and x = p->bitN; failed)
3412 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3414 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

3455 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3456 to keep the correct label reference count when adding/removing references

4044 Adding support for replacing ljmps with sjmps in jumptables
4045 generated for switch statements. For now you need to set the
4046 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4047 Now 4 algorithms for mcs51 jumptable generation are used:
4048 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4049 addresses loaded pc-relative for up to 112 cases and stack-pushing
4050 target addresses loaded with offset from dptr for up to 256 cases.

4080 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4082 * added libc directory. The current version of LibC contains string
4083 functions, ctype functions and macros and some functions of the
4084 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4085 be extensively tested in the future. Standard disclaimer here.
4086 Library is not automatically build yet. But one can build it by
4087 invoking 'make' inside the libc directory.

4098 * (pic16_storeForReturn): optimized return of 0,
4099 * (genCmp): experimental code for new genCmp which uses PIC18's
4100 special compare&skip instructions. Initial tests fail some times
4101 with variables grater than 1 byte in size, so new code is disabled,
4102 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4104 * (genCast): began a fix to optimize the casting of a bit to another
4105 bit, now assigning a bitfield to another bitfield will fail, sorry,
4106 * src/pic16/main.c: disabled the use of lr-support feature,
4107 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4113 * (isBankInstruction): modified to return 0 for no banking instruction,
4114 and 1 for banking instruction,
4115 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4116 caused stop processing pCodes after a inline assembly block,
4117 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4118 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4119 registers when it shouldn't,
4120 * src/pic16/ralloc.c (allocReg): add preliminary support for
4121 supporting a limited set of temporary registers,
4123 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4125 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4126 genDataPointerSet): ensure assignments always copy in MSB to LSB
4128 (loadRegFromAop): recognize CLRH optimization,
4129 (genFunction): optimize RECEIVE iCodes in reentrant functions
4131 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4133 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7131 loaded with the linker search paths (-L arguments) and the libraries
7132 to be linked with the current source (-l arguments). Changes
7133 currently will affect only the pic16 port.
7134 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7135 include path the port specific paths and port specific libraries,
7136 * gplink command now contains the $3 argument,
7137 * src/pic16/device.h,

7154 Documenting changes from previous commits.
7155 * configure.in (version 1.56),
7156 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7157 when generating output files to configure the pic16 library,
7158 but now I've commented it out, since gputils aren't installed in the
7159 SF compile farm, so library won't compile
7161 * device/lib/Makefile.in (version 1.56): initially I've added in
7162 target 'all' the prerequestive 'model-pic16' so it compiled the
7163 pic16 library, but now I've commented it out for the same reasons
7165 * added targets 'model-pic16' and 'objects-pic16' to compile the
7167 * added target 'port-specific-objects-pic16' to handle the
7168 generated libraries and copy them into the build/ directory
7169 * added target 'clean-intermediate-pic16' to clean intermediate
7170 files into pic16 directory
7171 * in target 'installdirs' added line to create directory pic16 in

7474 * added files genutils.c and genutils.h which contain gen*
7475 debugged and optimised functions extracted from gen.c
7477 * glue.c: added variable 'externs' which holds extern symbols,
7478 pic16emitRegularMap: is modified to properly handle relocatable
7479 symbols under the new scheme,
7480 pic16createInterruptVect: is modified
7481 pic16printPublics: is modified to emit 'global' assembler directives,
7482 added pic16_printExterns to print extern symbols,
7483 pic16glue: initializes stack/frame pointer in the beginning of
7484 the assembly output. Temporary hack, will be corrected later,
7485 because gplink yet does not support stack and SDCC does not
7486 yet support a type of crt0.o object to create the final binary.
7488 * Removed many lines that contain 8051 legacy code.
7489 * The code is finally placed under a 'code' directive.
7490 * Added port specific options.
7492 * _process_pragma: simplified since now we do not need *special*
7493 include file to define SFR registers. But a separate header
7494 will be needed. This will be developed later.
7495 * _pic16_parseOptions: added, parses port specific options:
7496 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7497 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7498 --preplace-udata-with=
7500 * _pic16_setDefaultOptions: modified to initialize section names,
7501 but hack is temporarly out of order since it needs improvement.
7502 * _pic16_genAssemblerPreamble: configuration words are emitted by
7503 their address instead of their name. This part is incomplete and
7504 supports only the 18Fxx2 devices. Other devices will emit an error
7505 during assembly since they do not contain the same set of config
7507 * _pic16_genIVT: is modified,
7509 * pcode.c: added definitions for some hardware registers that are needed
7511 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7512 All PCI entries are updated. Now LFSR is supported.
7513 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7514 * added pic16_newpCodeOpLit2 to support instructions with
7515 two literal arguments
7516 * pic16_pCode2str: corrected code that emits assembler instructions
7517 with two literal operands and those that have an access bit modifier
7518 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7519 this fixes a bug which caused some labels to be lost, when an
7520 assembler directive was added, i.e. banksel,
7521 * pic16_FixRegisterBanking: improved logic that causes the insertion
7523 * InlineFunction: functions that are called once, are not any more
7524 inlined. This can be a port option in the future,
7526 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7528 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7529 hold the corresponding uninitialized symbols,
7530 * pic16_allocProcessorRegister: registers have explicit marked the
7532 * pic16_allocInternalRegister: registers are explicit marked as
7534 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7535 processing list, so bit registers were lost,
7538 * ralloc.h: added field 'accessBank' and original symbol operand
7539 in register definition,
7540 * removed the field isMapped from register definition,
7542 ** Several functions have been removed from various sources:
7543 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7544 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7545 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7546 pic16_assignRelocatableRegisters
7548 ** others have been introduced:
7549 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7550 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7552 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7554 * support/scripts/inc2h.pl: changed definition of BIT_AT
7555 to emit 'sbit at' instead of 'bit at'. This was a request.
7557 PIC16 port related preliminary changes:
7558 * gen.c: prefixed function popRegFromString with
7559 pic16_ and all references to it corrected
7560 * pcode.c: all pic16_pc_* hardware registers prefixed
7561 with underscore (_),
7562 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7563 * ralloc.c: newReg(): when register is REG_SFR then
7564 set address to rIdx,
7565 pic16_allocProcessorRegister(): marks register wasUsed=0
7566 pic16_writeUsedRegs(): added a call to assign processor
7567 registers via pic16_assignFixedRegisters
7569 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7571 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7572 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7573 variables in unused register banks. Also the SSEG is placed
7574 wherever there is enough space for it, and IDATA can be anywhere
7575 in internal RAM. For now compile using -Wl-Y[stack_size].
7576 The mem file is different for this option as well, since it
7577 makes no sense of talking about DSEG lenght.
7579 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7581 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7582 in certain cases, e.g. when ROM assignment, patch provided
7583 from Albert den Haan.

7824 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7826 * src/SDCCast.c (decorateType): disabled a transformation I added in
7827 revision 1.188 (access to fields of a structure at an absolute address);
7828 it breaks with bitfields, extern declarations, and gcse analysis.
7829 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7830 could be assigned through a pointer, so don't complain.
7831 * src/SDCCast.c (astErrors),
7833 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7931 unlink new file before rename if new and old filenames are the same)
7933 2003-11-13 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7935 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
7936 uninitialized variables) for the mcs51. Set environment variable

8587 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8588 fetching of the pointer
8589 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8590 copied from genNearPointerSet()
8591 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8592 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8608 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8609 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8610 type for bits was changed. It resulted in bit variables becoming
8611 global, which is not permitted in PIC 14 assembly output.
8613 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8615 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8628 A few small changes that speed up the peephole optimizer.
8632 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8634 Try to make the peephole optimizer smarter by maintaining
8635 an association between the assembly source code and the
8636 iCodes that originated them. Put this information to use
8637 with a new peephole rule condition "notVolatile" so that
8638 the rules can be aggressive yet still safe.
8643 * src/mcs51/peeph.def
8645 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8649 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8650 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8651 if the left or right operand symbols have the accuse flag set.
8653 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8655 Changed the type of the result of the ! (NOT) operator to char;
8656 previously it returned the same type as the source. This allows
8657 us to eliminate all the genFloatNot functions (all of its target
8658 implementations were very buggy) since !float can use the same
8661 * src/SDCCicode.c (ast2iCode): ! returns char

8670 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8671 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8672 during interrupts. Ensure WSAVE is located at a shared bank address.
8673 2. Fixed page selection in some places
8674 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8675 the registers name strings.
8676 4. Fixed "signed / unsigned compare" compiler warnings.
8677 5. The PIC port manages its own allocation of the general purpose
8678 registers, but makes no attempt to reuse them. As a result when
8679 compiling it soon runs out of general purpose registers. Some
8680 additional code was added to the files pcode.c and device.c to walk
8681 through the function call tree and rename the registers so that they
8691 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8698 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8700 Made bitfield a distinct type from bit so that bitfields
8701 convert as per ANSI C and bits retain their traditional
8702 boolean style behaviour. Implemented bitfield support in
8710 * src/ds390/gen.c: bit v bitfield split
8711 * src/z80/gen.c: New support for bitfields
8712 * support/regression/tests/bitfields.c: reenabled z80,
8715 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8717 Rules 246.x, 247.x relate to bitfields, the others speed up
8718 access to xdata mapped I/O devices.
8720 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8722 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8724 Cleaned up genPackBits and genUnpackBits and added two helper
8725 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8726 for literal assignments in genPackBits (thanks to Frieder for
8732 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8734 Fixed bug #748310 (pointer to function type mishandled when the
8735 function name is omitted). Also fixed a SIGSEGV when a function
8736 attribute (reentrant, etc) is used on a non-function or on a
8737 function but misplaced before the parameter list.
8739 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8741 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8742 * support/Util/SDCCerr.h,
8743 * support/Util/SDCCerr.c: Added func attr misuse error msg

8764 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8766 Made the constant following the "interrupt" keyword optional. If
8767 omitted, the function will not automatically be given an entry
8768 in the interrupt vector table (similar to #pragma NOIV, but
8769 less syntacticly kludgy). The interrupt number is also now
8770 range checked. Also fixed a bug in the high order bit example

8781 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
8783 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
8784 * src/SDCCicode.c (operandOperation): rewritten some ops
8785 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8786 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8788 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8789 be re-activated by defining REDUCE_LITERALS)
8790 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8791 unsigned, but are signed by default
8792 * src/SDCCval.c (constVal): rearranged
8793 * src/SDCCval.c (valMod): preliminary fix
8794 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8836 constants are unsigned; added recognition of "u" flag for unsigned
8837 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
8838 * src/SDCCval.c (valDiv, valMod): fixed signdness
8839 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
8840 signedness of modulo, left and right shift

9299 * src/SDCCmain.c: linkOptions is changed to set *,
9300 added if/endif conditional macros to remove options help
9301 messages from optionsTable when a port is not configured, added
9302 support for the PIc16 port in the ports table, when executing
9303 the compiler with no port specified on command line, a default
9304 port is selected with the new macro DEFAULT_PORT which is
9305 defined in port.h, in setDefaultOptions() linkOptions is removed
9306 from initialization assignment, since now it is a set,
9307 parseCmdLine uses setParseWithComma for linkOptions, in
9308 linkEdit() linkOptions are accessed with new function indexSet()
9309 which returns the i'th item of a set variable. See SDCCset.c, in
9310 linkEdit() when calling buildCmdLine(), added linkOptions as
9311 last argument. Now users can pass arguments to gplink via the
9312 -Wl option, main() uses pic16glue() to glue up pic16 programs

9324 * src/pic16/glue.c: commented out some error producing lines
9325 * src/pic16/main.c: __config directives are commented out to stop
9326 gpasm complaining and test the linkage with gplink, _linkCmd and
9327 _asmCmd changed to be more gplink and gpasm friendly
9328 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9329 produced an error when parsed, peep rule 12 is added to utilize
9330 movff, but it is commented out since the pCode does not support
9331 yet a command with 2 address arguments
9333 2003-05-18 <johan AT balder>
9335 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9360 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9362 2003-05-11 Borut Razem <borut.razem AT siol.net>
9364 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9365 the path of bin directory, so that PATH is the only env. variable, which has to be set
9366 in case of standard installation.
9367 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

10383 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10384 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10385 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10387 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10388 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10390 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10391 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10393 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10394 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10396 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10398 * in \sdcc\as\mcs51\ changed these files in order to create an
10399 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10400 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10401 following files to include the previous two files: aslink.dsp,
10402 Makefile.aslink, Makefile.bcc, and Makefile.in.
10404 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10405 .adb instead of .cdb
10407 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10409 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10410 value from option --iram-size.
10412 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10414 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10417 2002-09-18 <wiml AT hhhh.org>
10419 * SDCClrange.h: exposed setFromRange() and setToRange()
10420 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10421 packRegsForAccUse() (bug 542397)
10422 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10423 multiple times and emitting the fetch operations more than once
10424 added aopGetUsesAcc() function to allow binary operators to
10425 fetch their operands in the correct order; made genMinus() emit
10426 compact code for X = LITERAL - Y
10428 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10429 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10430 sprintf() in line 1267.
10432 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10433 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10436 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10437 Changes to aslink (All the changes are marked with 'JCF'):
10439 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10442 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10443 area BSEG. Also moves, if possible, the DATA area down into the internal
10444 ram so more space is available.
10446 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10449 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10450 not bytes. Function summary() which creates a memory usage summary
10451 file with extension .mem. Reports of overlaping stack and small stack
10452 size. If the space for the stack is less than 16 bytes aslink trows a
10455 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10456 the 8051. Option 'y' for memory summary output file.
10458 Changes to sdcc (All the changes are marked with 'JCF'):
10460 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10462 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10463 overlaying area for it (uses RegBankUsed[4]).
10465 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10466 bank zero as used by default. By default aslink locates the stack
10467 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10468 the creation of the .mem file. Delegates the allocation of data area
10469 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10470 the begining of the stack area to aslink.
10472 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10473 glue() in SDCCglue.c creates an area for it.
10475 2002-09-03 Borut Razem <borut.razem AT siol.net>
10476 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10477 sdcc/src/pic/glue.c:
10478 introduced atexit() handler for teporay files removal in case of
10479 errors, assertions, ...
10481 2002-08-29 Borut Razem <borut.razem AT siol.net>
10482 * sdcc/support/cpp2/auto-host_vc_in.h:
10483 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10484 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10485 Maybe there is a similar problem with BORLANDC? It should be checked!
10487 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10488 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10489 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10490 was not executed, and the compiler (cl) launched a warning:
10491 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10493 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10494 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10496 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10497 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10499 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10500 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10501 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10502 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10503 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10504 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10505 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10506 - added Release configuration in VS projects
10507 - review of compiler an linker options
10508 - VC .exe files are generated in bin_vc directory, not to interfere
10509 with binaries generated from other projects (cygwin, mingw, bcc ...)
10511 * sdcc/src/yacc.dsp: added
10513 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10514 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10515 and insert the version number definitions from .version
10517 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10519 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10520 added - genarate auto-host.h using auto-host_vc_in.h as template
10523 removed from CVS, generated automatically
10525 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10526 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10528 2002-08-11 Borut Razem <borut.razem AT siol.net>
10529 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10531 2002-08-10 Borut Razem <borut.razem AT siol.net>
10532 * src/SDCCmain.c (main):
10533 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10534 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10535 The consequence was that some temporary files were not removed.
10538 unification of code in functions tempfilename() and tempfile():
10539 function tempnam() is defined in Visual Studio 6.0 and .NET
10541 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10543 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10544 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10545 - removed compiler command line option /WX: Treats all warnings as errors
10546 - update a list of source files, included into the project
10548 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10549 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10550 changed project type to Generic Project so that can be correcly converted to VS.NET project
10552 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10554 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10556 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10558 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10559 added return 0 statements after assert() to make compiler happy
10561 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10562 added newline in the def file to keep MSC compiler satisfied
10564 * sdcc/src/z80/gen.c:
10565 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10566 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10567 - solved MSC error in function aopDump()
10569 * sdcc_vc.h: define PREFIX as "\\sdcc"
10571 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10572 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10575 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10576 - Rewrote the register banking algorithm.
10577 - Added pCode live-range analysis to registers (for now, only non-used and
10578 singly-used registers optimized away)
10580 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10582 * 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.

10607 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
10609 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10611 2002-03-28 Johan Knol <johan AT balder>
10613 * src/SDCCval.c: fixed bug #532436
10615 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10617 Added "char *Processor" field to the port structure.
10620 Added -p option. Allows port dependent processor to be specified.
10623 Initialized the new field char *Processor field to NULL in all ports
10626 Compiler generated registers for interrupt context saving
10627 were not getting allocated.
10629 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10632 Fixed left shift. Will promote the left side of a left shift
10633 if a) left shifting more than size of operand or b) when assigned
10634 to something size > size of left side
10636 2002-03-14 Scott Dattalo <scott AT dattalo.com>

10640 analysis is restructured. ...
10642 * src/pic/device.h:
10645 * src/pic/device.c:
10646 Added. device.c is a PIC port hack to accomodate variations

10744 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10746 * sdcc/src/SDCCloop.c:
10747 Previous fix was not good. basic blocks that have "break" or "return" are
10748 not really partof a loop , but live ranges used in these blocks should
10749 be live thru the entire loop, so set partOfLoop but don't add them to
10752 2002-02-21 <johan AT FRIJA>
10754 * src/SDCCcse.c: fixed bug #514308
10756 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10759 Fixed BUG #519583. If a conditional block ended in a return/break
