512 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
514 Enabled VPATH feature: changed nearly all Makefiles (149 files).
515 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
517 One basic decision: e.g. src/clean.mk includes further files. In order
518 to make this work there are two solutions:
519 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
520 run configure on them. This way they can use
521 'include $(srcdir)/port-clean.mk'
522 - always include clean.mk by the Makefile at the same level. To avoid
523 that `make clean` tries to include and build Makefile.dep the
524 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
525 implemented, because now even `make uninstall` doesn't create
526 Makefile.in. clean.mk could be eliminated by pasting it in
529 * debugger/mcs51/Makefile.in: build own objects from library sources
530 (SLIB, SDCC) in current directory
532 * configure, configure.in: renamed --disable-device-lib-build in
533 --disable-device-lib; added --enable-doc, the required tools are
534 searched by configure; added result message; the toolchain for the
535 belonging ports are now only built, if the port is enabled.
537 * support/regression/*: all output is written in directory gen, because
538 the fwk and ports directories don't livet in the build tree using vpath
540 * doc/sdccman.lyx: renamed --disable-device-lib-build to
541 --disable-device-lib, added --enable-doc, added section VPATH
543 * sim/ucsim/configure.in,
544 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
545 z80 are enabled by default
547 2006-04-24 Raphael Neider <rneider AT web.de>
549 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
550 to config word, "pic14_"-prefixed some extern functions
551 (pic14_emitConfigWord): emit __config directive(s) if assignment to
552 config word has been found
553 * src/pic/device.h: added prototypes
554 * src/pic/pcode.c: added "pic14_"-prefix where needed

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

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

3225 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3226 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3227 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3228 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3229 always available in leading double underscore form. The C99 support is
3230 mostly missing, but it's a start.
3231 * support/regression/tests/bug-227710.c: fixed nonconforming use of

3310 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3312 * device/lib/printf_large.c: removed inline assembly for portability and
3313 readability. Use printf_fast if speed or size are more important.
3314 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3315 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3317 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3319 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3320 prevent compiler warning
3322 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3324 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3325 moved to level 0 and declared as static. Also they are explicit
3326 placed in access bank. This was necessery because some times they
3327 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3328 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3329 optimizations. Currently only compare to unsigned char is implemented,
3330 * src/pic16/gen.c: added fReturnIdx array,
3331 * (struct resolvedIfx) is moved to gen.h and made public,
3332 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3333 * (aopForSym): added an optimization to directly store in stack of
3334 the operand of a SEND iCode,
3335 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3336 but as registers instead (AOP_REG) using the fReturnIdx array,
3337 * (pic16_freeAsmop): remove the freed register from the
3338 _G.sregsAlloc field,
3339 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3340 a compare of 'WREG',
3341 * (pic16_popGetTempRegCond): changed function prototype, now
3342 function takes also a bitVector argument v which holds the current
3343 set of registers that are allocated for stack access by aopForSym,
3344 registers allocated in aopForSym for accessing stack symbols are not
3345 any more part of the functions usedRegs field,
3346 * (genCall): some times aopOp is called for a stack variable to be
3347 send, aopForSym might perform the push, if this is true make sure
3348 that genCall doesn't push the variable twice by testing _G.resDirect,
3349 * (genFunction): changed testing for unspecified interrupt number
3350 from 256 to INTNO_UNSPEC,
3351 * modified selection scheme of frame pointer generation. Previously
3352 if function did use local registers a frame pointer was generated,
3353 now a frame pointer is generated only if function has arguments
3354 (that need PLUSW2 register access), or has stack arguments, or the
3355 compiler is not instructed to omit the frame pointer,
3356 * (genEndFunction): before restoring local registers that were saved
3357 in the function preamble, also restore the registers that *might*
3358 have been allocated for stack access,
3359 * (genRet): removed some old comments,
3360 * (genCmp, the active (RN's) version): added a call to the
3361 pic16_genCmp_special function to perform the compare with a more
3362 robust and optimized way,
3363 * (genInline): a feature has been added in inline code generation,
3364 which allows a wildcard variable substitution when writing inline
3365 assembly. Code is incomplete and experimental therefore undocumented,
3366 * (genCast): changed order of aopOp for result and right to allow
3367 aopForSym to directly load the result if possible,
3368 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3369 perform an optimized compare on some selected special occasions,
3370 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3371 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3372 generate an IVT any more,
3373 * src/pic16/main.c (pic16_optionsTable): added command line option
3375 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3376 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3378 * src/pic16/NOTES: Raphael Neider added in list of active developers
3379 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3380 jumptable_end to prevent bug #,
3381 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3382 inCond and outCond fields,
3383 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3384 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3385 turn off register spilling,
3386 * (packRegsForOneUse): synced with other ports' versions although it
3387 is not used currently,
3388 * (pic16_packRegisters): added an optimization while reading
3389 structure bitfields, some registers may be saved (malloc code is
3390 decreased by 80 bytes)
3392 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3394 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3395 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3396 this can be optimized more?
3398 2005-03-10 Raphael Neider <rneider AT web.de>
3400 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3401 genNearPointerGet): (hopefully) fixed access to bitfields via
3402 pointers (p->bitN = x; and x = p->bitN; failed)
3404 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

3445 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3447 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
3448 to keep the correct label reference count when adding/removing references
3449 to labels. A peephole file using this is appended to patch #1144962.
3451 2005-02-14 Raphael Neider <rneider AT web.de>

4036 Adding support for replacing ljmps with sjmps in jumptables
4037 generated for switch statements. For now you need to set the
4038 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4039 Now 4 algorithms for mcs51 jumptable generation are used:
4040 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4041 addresses loaded pc-relative for up to 112 cases and stack-pushing
4042 target addresses loaded with offset from dptr for up to 256 cases.

4072 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4074 * added libc directory. The current version of LibC contains string
4075 functions, ctype functions and macros and some functions of the
4076 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4077 be extensively tested in the future. Standard disclaimer here.
4078 Library is not automatically build yet. But one can build it by
4079 invoking 'make' inside the libc directory.
4080 * added ADC library under libio. Preliminary version yet.

4090 * (pic16_storeForReturn): optimized return of 0,
4091 * (genCmp): experimental code for new genCmp which uses PIC18's
4092 special compare&skip instructions. Initial tests fail some times
4093 with variables grater than 1 byte in size, so new code is disabled,
4094 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4096 * (genCast): began a fix to optimize the casting of a bit to another
4097 bit, now assigning a bitfield to another bitfield will fail, sorry,
4098 * src/pic16/main.c: disabled the use of lr-support feature,
4099 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4102 bits with offset (case PO_GPR_BIT),
4103 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
4105 * (isBankInstruction): modified to return 0 for no banking instruction,
4106 and 1 for banking instruction,
4107 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4108 caused stop processing pCodes after a inline assembly block,
4109 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4110 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4111 registers when it shouldn't,
4112 * src/pic16/ralloc.c (allocReg): add preliminary support for
4113 supporting a limited set of temporary registers,
4115 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4117 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4118 genDataPointerSet): ensure assignments always copy in MSB to LSB
4120 (loadRegFromAop): recognize CLRH optimization,
4121 (genFunction): optimize RECEIVE iCodes in reentrant functions
4123 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4125 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7123 loaded with the linker search paths (-L arguments) and the libraries
7124 to be linked with the current source (-l arguments). Changes
7125 currently will affect only the pic16 port.
7126 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7127 include path the port specific paths and port specific libraries,
7128 * gplink command now contains the $3 argument,
7129 * src/pic16/device.h,

7146 Documenting changes from previous commits.
7147 * configure.in (version 1.56),
7148 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7149 when generating output files to configure the pic16 library,
7150 but now I've commented it out, since gputils aren't installed in the
7151 SF compile farm, so library won't compile
7153 * device/lib/Makefile.in (version 1.56): initially I've added in
7154 target 'all' the prerequestive 'model-pic16' so it compiled the
7155 pic16 library, but now I've commented it out for the same reasons
7157 * added targets 'model-pic16' and 'objects-pic16' to compile the
7159 * added target 'port-specific-objects-pic16' to handle the
7160 generated libraries and copy them into the build/ directory
7161 * added target 'clean-intermediate-pic16' to clean intermediate
7162 files into pic16 directory
7163 * in target 'installdirs' added line to create directory pic16 in

7474 added pic16_printExterns to print extern symbols,
7475 pic16glue: initializes stack/frame pointer in the beginning of
7476 the assembly output. Temporary hack, will be corrected later,
7477 because gplink yet does not support stack and SDCC does not
7478 yet support a type of crt0.o object to create the final binary.
7480 * Removed many lines that contain 8051 legacy code.
7481 * The code is finally placed under a 'code' directive.
7482 * Added port specific options.
7484 * _process_pragma: simplified since now we do not need *special*
7485 include file to define SFR registers. But a separate header
7486 will be needed. This will be developed later.
7487 * _pic16_parseOptions: added, parses port specific options:
7488 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7489 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7490 --preplace-udata-with=
7492 * _pic16_setDefaultOptions: modified to initialize section names,
7493 but hack is temporarly out of order since it needs improvement.
7494 * _pic16_genAssemblerPreamble: configuration words are emitted by
7495 their address instead of their name. This part is incomplete and
7496 supports only the 18Fxx2 devices. Other devices will emit an error
7497 during assembly since they do not contain the same set of config
7499 * _pic16_genIVT: is modified,
7501 * pcode.c: added definitions for some hardware registers that are needed
7503 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7504 All PCI entries are updated. Now LFSR is supported.
7505 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7506 * added pic16_newpCodeOpLit2 to support instructions with
7507 two literal arguments
7508 * pic16_pCode2str: corrected code that emits assembler instructions
7509 with two literal operands and those that have an access bit modifier
7510 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7511 this fixes a bug which caused some labels to be lost, when an
7512 assembler directive was added, i.e. banksel,
7513 * pic16_FixRegisterBanking: improved logic that causes the insertion
7515 * InlineFunction: functions that are called once, are not any more
7516 inlined. This can be a port option in the future,
7518 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7520 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7521 hold the corresponding uninitialized symbols,
7522 * pic16_allocProcessorRegister: registers have explicit marked the
7524 * pic16_allocInternalRegister: registers are explicit marked as
7526 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7527 processing list, so bit registers were lost,
7530 * ralloc.h: added field 'accessBank' and original symbol operand
7531 in register definition,
7532 * removed the field isMapped from register definition,
7534 ** Several functions have been removed from various sources:
7535 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7536 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7537 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7538 pic16_assignRelocatableRegisters
7540 ** others have been introduced:
7541 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7542 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7544 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7546 * support/scripts/inc2h.pl: changed definition of BIT_AT
7547 to emit 'sbit at' instead of 'bit at'. This was a request.
7549 PIC16 port related preliminary changes:
7550 * gen.c: prefixed function popRegFromString with
7551 pic16_ and all references to it corrected
7552 * pcode.c: all pic16_pc_* hardware registers prefixed
7553 with underscore (_),
7554 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7555 * ralloc.c: newReg(): when register is REG_SFR then
7556 set address to rIdx,
7557 pic16_allocProcessorRegister(): marks register wasUsed=0
7558 pic16_writeUsedRegs(): added a call to assign processor
7559 registers via pic16_assignFixedRegisters
7561 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7563 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7564 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7565 variables in unused register banks. Also the SSEG is placed
7566 wherever there is enough space for it, and IDATA can be anywhere
7567 in internal RAM. For now compile using -Wl-Y[stack_size].
7568 The mem file is different for this option as well, since it
7569 makes no sense of talking about DSEG lenght.
7571 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7573 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7574 in certain cases, e.g. when ROM assignment, patch provided
7575 from Albert den Haan.

7818 * src/SDCCast.c (decorateType): disabled a transformation I added in
7819 revision 1.188 (access to fields of a structure at an absolute address);
7820 it breaks with bitfields, extern declarations, and gcse analysis.
7821 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7822 could be assigned through a pointer, so don't complain.
7823 * src/SDCCast.c (astErrors),
7825 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

7927 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
7928 uninitialized variables) for the mcs51. Set environment variable
7929 SDCC_GENRAMCLEAR to test.
7930 xdata initialization slightly shorter
7932 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8579 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8580 fetching of the pointer
8581 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8582 copied from genNearPointerSet()
8583 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8584 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8600 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8601 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8602 type for bits was changed. It resulted in bit variables becoming
8603 global, which is not permitted in PIC 14 assembly output.

8620 A few small changes that speed up the peephole optimizer.
8624 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8626 Try to make the peephole optimizer smarter by maintaining
8627 an association between the assembly source code and the
8628 iCodes that originated them. Put this information to use
8629 with a new peephole rule condition "notVolatile" so that
8630 the rules can be aggressive yet still safe.
8635 * src/mcs51/peeph.def
8637 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8641 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),

8643 if the left or right operand symbols have the accuse flag set.
8645 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8647 Changed the type of the result of the ! (NOT) operator to char;
8648 previously it returned the same type as the source. This allows
8649 us to eliminate all the genFloatNot functions (all of its target
8650 implementations were very buggy) since !float can use the same

8662 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8663 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8664 during interrupts. Ensure WSAVE is located at a shared bank address.
8665 2. Fixed page selection in some places
8666 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8667 the registers name strings.
8668 4. Fixed "signed / unsigned compare" compiler warnings.
8669 5. The PIC port manages its own allocation of the general purpose
8670 registers, but makes no attempt to reuse them. As a result when
8671 compiling it soon runs out of general purpose registers. Some
8672 additional code was added to the files pcode.c and device.c to walk
8673 through the function call tree and rename the registers so that they
8683 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

8690 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8692 Made bitfield a distinct type from bit so that bitfields
8693 convert as per ANSI C and bits retain their traditional
8694 boolean style behaviour. Implemented bitfield support in
8702 * src/ds390/gen.c: bit v bitfield split
8703 * src/z80/gen.c: New support for bitfields
8704 * support/regression/tests/bitfields.c: reenabled z80,
8707 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8709 Rules 246.x, 247.x relate to bitfields, the others speed up
8710 access to xdata mapped I/O devices.
8712 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8714 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8716 Cleaned up genPackBits and genUnpackBits and added two helper
8717 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8718 for literal assignments in genPackBits (thanks to Frieder for
8724 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8726 Fixed bug #748310 (pointer to function type mishandled when the
8727 function name is omitted). Also fixed a SIGSEGV when a function
8728 attribute (reentrant, etc) is used on a non-function or on a
8729 function but misplaced before the parameter list.
8731 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8733 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

8756 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8758 Made the constant following the "interrupt" keyword optional. If
8759 omitted, the function will not automatically be given an entry
8760 in the interrupt vector table (similar to #pragma NOIV, but
8761 less syntacticly kludgy). The interrupt number is also now
8762 range checked. Also fixed a bug in the high order bit example

8776 * src/SDCCicode.c (operandOperation): rewritten some ops
8777 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8778 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8780 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8781 be re-activated by defining REDUCE_LITERALS)
8782 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8783 unsigned, but are signed by default
8784 * src/SDCCval.c (constVal): rearranged
8785 * src/SDCCval.c (valMod): preliminary fix
8786 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9291 * src/SDCCmain.c: linkOptions is changed to set *,
9292 added if/endif conditional macros to remove options help
9293 messages from optionsTable when a port is not configured, added
9294 support for the PIc16 port in the ports table, when executing
9295 the compiler with no port specified on command line, a default
9296 port is selected with the new macro DEFAULT_PORT which is
9297 defined in port.h, in setDefaultOptions() linkOptions is removed
9298 from initialization assignment, since now it is a set,
9299 parseCmdLine uses setParseWithComma for linkOptions, in
9300 linkEdit() linkOptions are accessed with new function indexSet()
9301 which returns the i'th item of a set variable. See SDCCset.c, in
9302 linkEdit() when calling buildCmdLine(), added linkOptions as
9303 last argument. Now users can pass arguments to gplink via the
9304 -Wl option, main() uses pic16glue() to glue up pic16 programs

9317 * src/pic16/main.c: __config directives are commented out to stop
9318 gpasm complaining and test the linkage with gplink, _linkCmd and
9319 _asmCmd changed to be more gplink and gpasm friendly
9320 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9321 produced an error when parsed, peep rule 12 is added to utilize
9322 movff, but it is commented out since the pCode does not support
9323 yet a command with 2 address arguments
9325 2003-05-18 <johan AT balder>
9327 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9354 2003-05-11 Borut Razem <borut.razem AT siol.net>
9356 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9357 the path of bin directory, so that PATH is the only env. variable, which has to be set
9358 in case of standard installation.

10377 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10379 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10380 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10382 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10383 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10385 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10386 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10388 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10390 * in \sdcc\as\mcs51\ changed these files in order to create an
10391 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10392 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10393 following files to include the previous two files: aslink.dsp,
10394 Makefile.aslink, Makefile.bcc, and Makefile.in.
10396 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10397 .adb instead of .cdb
10399 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10401 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10402 value from option --iram-size.
10404 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10406 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10409 2002-09-18 <wiml AT hhhh.org>
10411 * SDCClrange.h: exposed setFromRange() and setToRange()
10412 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10413 packRegsForAccUse() (bug 542397)
10414 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10415 multiple times and emitting the fetch operations more than once
10416 added aopGetUsesAcc() function to allow binary operators to
10417 fetch their operands in the correct order; made genMinus() emit
10418 compact code for X = LITERAL - Y
10420 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10421 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10422 sprintf() in line 1267.
10424 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10425 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10428 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10429 Changes to aslink (All the changes are marked with 'JCF'):
10431 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10434 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10435 area BSEG. Also moves, if possible, the DATA area down into the internal
10436 ram so more space is available.
10438 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10441 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10442 not bytes. Function summary() which creates a memory usage summary
10443 file with extension .mem. Reports of overlaping stack and small stack
10444 size. If the space for the stack is less than 16 bytes aslink trows a
10447 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10448 the 8051. Option 'y' for memory summary output file.
10450 Changes to sdcc (All the changes are marked with 'JCF'):
10452 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10454 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10455 overlaying area for it (uses RegBankUsed[4]).
10457 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10458 bank zero as used by default. By default aslink locates the stack
10459 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10460 the creation of the .mem file. Delegates the allocation of data area
10461 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10462 the begining of the stack area to aslink.
10464 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10465 glue() in SDCCglue.c creates an area for it.
10467 2002-09-03 Borut Razem <borut.razem AT siol.net>
10468 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10469 sdcc/src/pic/glue.c:
10470 introduced atexit() handler for teporay files removal in case of
10471 errors, assertions, ...
10473 2002-08-29 Borut Razem <borut.razem AT siol.net>
10474 * sdcc/support/cpp2/auto-host_vc_in.h:
10475 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10476 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10477 Maybe there is a similar problem with BORLANDC? It should be checked!
10479 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10480 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10481 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10482 was not executed, and the compiler (cl) launched a warning:
10483 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10485 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10486 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10488 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10489 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10491 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10492 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10493 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10494 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10495 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10496 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10497 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10498 - added Release configuration in VS projects
10499 - review of compiler an linker options
10500 - VC .exe files are generated in bin_vc directory, not to interfere
10501 with binaries generated from other projects (cygwin, mingw, bcc ...)
10503 * sdcc/src/yacc.dsp: added
10505 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10506 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10507 and insert the version number definitions from .version
10509 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10511 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10512 added - genarate auto-host.h using auto-host_vc_in.h as template
10515 removed from CVS, generated automatically
10517 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10518 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10520 2002-08-11 Borut Razem <borut.razem AT siol.net>
10521 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10523 2002-08-10 Borut Razem <borut.razem AT siol.net>
10524 * src/SDCCmain.c (main):
10525 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10526 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10527 The consequence was that some temporary files were not removed.
10530 unification of code in functions tempfilename() and tempfile():
10531 function tempnam() is defined in Visual Studio 6.0 and .NET
10533 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10535 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10536 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10537 - removed compiler command line option /WX: Treats all warnings as errors
10538 - update a list of source files, included into the project
10540 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10541 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10542 changed project type to Generic Project so that can be correcly converted to VS.NET project
10544 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10546 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10548 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10550 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10551 added return 0 statements after assert() to make compiler happy
10553 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10554 added newline in the def file to keep MSC compiler satisfied
10556 * sdcc/src/z80/gen.c:
10557 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10558 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10559 - solved MSC error in function aopDump()
10561 * sdcc_vc.h: define PREFIX as "\\sdcc"
10563 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10564 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10567 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10568 - Rewrote the register banking algorithm.
10569 - Added pCode live-range analysis to registers (for now, only non-used and
10570 singly-used registers optimized away)
10572 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
10574 * 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.

10601 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10603 2002-03-28 Johan Knol <johan AT balder>
10605 * src/SDCCval.c: fixed bug #532436
10607 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10609 Added "char *Processor" field to the port structure.
10612 Added -p option. Allows port dependent processor to be specified.
10615 Initialized the new field char *Processor field to NULL in all ports
10618 Compiler generated registers for interrupt context saving
10619 were not getting allocated.
10621 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10624 Fixed left shift. Will promote the left side of a left shift
10625 if a) left shifting more than size of operand or b) when assigned
10626 to something size > size of left side
10628 2002-03-14 Scott Dattalo <scott AT dattalo.com>

10736 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10738 * sdcc/src/SDCCloop.c:
10739 Previous fix was not good. basic blocks that have "break" or "return" are
10740 not really partof a loop , but live ranges used in these blocks should
10741 be live thru the entire loop, so set partOfLoop but don't add them to
10744 2002-02-21 <johan AT FRIJA>
10746 * src/SDCCcse.c: fixed bug #514308
10748 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
