542 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
544 Enabled VPATH feature: changed nearly all Makefiles (149 files).
545 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
547 One basic decision: e.g. src/clean.mk includes further files. In order
548 to make this work there are two solutions:
549 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
550 run configure on them. This way they can use
551 'include $(srcdir)/port-clean.mk'
552 - always include clean.mk by the Makefile at the same level. To avoid
553 that `make clean` tries to include and build Makefile.dep the
554 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
555 implemented, because now even `make uninstall` doesn't create
556 Makefile.in. clean.mk could be eliminated by pasting it in
559 * debugger/mcs51/Makefile.in: build own objects from library sources
560 (SLIB, SDCC) in current directory
562 * configure, configure.in: renamed --disable-device-lib-build in
563 --disable-device-lib; added --enable-doc, the required tools are
564 searched by configure; added result message; the toolchain for the
565 belonging ports are now only built, if the port is enabled.
567 * support/regression/*: all output is written in directory gen, because
568 the fwk and ports directories don't livet in the build tree using vpath
570 * doc/sdccman.lyx: renamed --disable-device-lib-build to
571 --disable-device-lib, added --enable-doc, added section VPATH
573 * sim/ucsim/configure.in,
574 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
575 z80 are enabled by default
577 2006-04-24 Raphael Neider <rneider AT web.de>
579 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
580 to config word, "pic14_"-prefixed some extern functions
581 (pic14_emitConfigWord): emit __config directive(s) if assignment to
582 config word has been found
583 * src/pic/device.h: added prototypes
584 * src/pic/pcode.c: added "pic14_"-prefix where needed

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

946 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
948 2006-03-06 Borut Razem <borut.razem AT siol.net>
950 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
951 made the linker quiet
953 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
955 * src/pic16/gen.c (genPcall): fixed bug #1443644
956 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
957 which dumps before the function entry point a data byte which represents
958 the number of the local variables used by the specified function, added
959 'xinst' for initial support for Extended Instruction Support,
960 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
961 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
962 port->fun_prefix anymore (may change later),
963 (genFunction, genEndFunction): do not store/restore local registers for
964 _main (this should take care the --main-return command line option in
966 (genOr): removed some legacy pic-port instructions,
967 * src/pic16/genarith.c (genAddLit): re-enabled old code because
968 performing operations with SFR's causes data to be written more than

970 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
972 * src/pic16/main.c (_process_pragma): stack bound checking did not take

975 --extended or -y for Extended Instruction Support,
976 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
977 (deassignLRs): *** perhaps the most important change, old 'for' code
978 (commented out for reference), didn't account for some registers which
979 were left marked 'not free' after a pointer operation. The change
980 reduces register usage a lot in some cases

3253 * src/SDCCglobal.h (struct options),
3255 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
3256 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
3257 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
3258 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
3259 always available in leading double underscore form. The C99 support is
3260 mostly missing, but it's a start.
3261 * support/regression/tests/bug-227710.c: fixed nonconforming use of
3262 reserved identifier "__data".

3340 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
3342 * device/lib/printf_large.c: removed inline assembly for portability and
3343 readability. Use printf_fast if speed or size are more important.
3344 * src/pic16/gen.c: removed conditions around use of DEBUGpc
3345 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
3347 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
3349 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
3350 prevent compiler warning
3352 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
3354 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
3355 moved to level 0 and declared as static. Also they are explicit
3356 placed in access bank. This was necessery because some times they
3357 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
3358 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
3359 optimizations. Currently only compare to unsigned char is implemented,
3360 * src/pic16/gen.c: added fReturnIdx array,
3361 * (struct resolvedIfx) is moved to gen.h and made public,
3362 * (struct _G): added sregsAlloc and sregsAllocSet fields,
3363 * (aopForSym): added an optimization to directly store in stack of
3364 the operand of a SEND iCode,
3365 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
3366 but as registers instead (AOP_REG) using the fReturnIdx array,
3367 * (pic16_freeAsmop): remove the freed register from the
3368 _G.sregsAlloc field,
3369 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
3370 a compare of 'WREG',
3371 * (pic16_popGetTempRegCond): changed function prototype, now
3372 function takes also a bitVector argument v which holds the current
3373 set of registers that are allocated for stack access by aopForSym,
3374 registers allocated in aopForSym for accessing stack symbols are not
3375 any more part of the functions usedRegs field,
3376 * (genCall): some times aopOp is called for a stack variable to be
3377 send, aopForSym might perform the push, if this is true make sure
3378 that genCall doesn't push the variable twice by testing _G.resDirect,
3379 * (genFunction): changed testing for unspecified interrupt number
3380 from 256 to INTNO_UNSPEC,
3381 * modified selection scheme of frame pointer generation. Previously
3382 if function did use local registers a frame pointer was generated,
3383 now a frame pointer is generated only if function has arguments
3384 (that need PLUSW2 register access), or has stack arguments, or the
3385 compiler is not instructed to omit the frame pointer,
3386 * (genEndFunction): before restoring local registers that were saved
3387 in the function preamble, also restore the registers that *might*
3388 have been allocated for stack access,
3389 * (genRet): removed some old comments,
3390 * (genCmp, the active (RN's) version): added a call to the
3391 pic16_genCmp_special function to perform the compare with a more
3392 robust and optimized way,
3393 * (genInline): a feature has been added in inline code generation,
3394 which allows a wildcard variable substitution when writing inline
3395 assembly. Code is incomplete and experimental therefore undocumented,
3396 * (genCast): changed order of aopOp for result and right to allow
3397 aopForSym to directly load the result if possible,
3398 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
3399 perform an optimized compare on some selected special occasions,
3400 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
3401 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
3402 generate an IVT any more,
3403 * src/pic16/main.c (pic16_optionsTable): added command line option
3405 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
3406 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
3408 * src/pic16/NOTES: Raphael Neider added in list of active developers
3409 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
3410 jumptable_end to prevent bug #,
3411 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
3412 inCond and outCond fields,
3413 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
3414 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
3415 turn off register spilling,
3416 * (packRegsForOneUse): synced with other ports' versions although it
3417 is not used currently,
3418 * (pic16_packRegisters): added an optimization while reading
3419 structure bitfields, some registers may be saved (malloc code is
3420 decreased by 80 bytes)
3422 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
3424 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
3425 left is a bitfield, if yes, then don't optimize assignment. Perhaps
3426 this can be optimized more?
3428 2005-03-10 Raphael Neider <rneider AT web.de>
3430 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
3431 genNearPointerGet): (hopefully) fixed access to bitfields via
3432 pointers (p->bitN = x; and x = p->bitN; failed)
3434 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
3436 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4066 Adding support for replacing ljmps with sjmps in jumptables
4067 generated for switch statements. For now you need to set the
4068 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4069 Now 4 algorithms for mcs51 jumptable generation are used:
4070 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4071 addresses loaded pc-relative for up to 112 cases and stack-pushing
4072 target addresses loaded with offset from dptr for up to 256 cases.

4102 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4104 * added libc directory. The current version of LibC contains string
4105 functions, ctype functions and macros and some functions of the
4106 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4107 be extensively tested in the future. Standard disclaimer here.
4108 Library is not automatically build yet. But one can build it by
4109 invoking 'make' inside the libc directory.
4110 * added ADC library under libio. Preliminary version yet.

4120 * (pic16_storeForReturn): optimized return of 0,
4121 * (genCmp): experimental code for new genCmp which uses PIC18's
4122 special compare&skip instructions. Initial tests fail some times
4123 with variables grater than 1 byte in size, so new code is disabled,
4124 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4126 * (genCast): began a fix to optimize the casting of a bit to another
4127 bit, now assigning a bitfield to another bitfield will fail, sorry,
4128 * src/pic16/main.c: disabled the use of lr-support feature,
4129 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4135 * (isBankInstruction): modified to return 0 for no banking instruction,
4136 and 1 for banking instruction,
4137 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4138 caused stop processing pCodes after a inline assembly block,
4139 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4140 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4141 registers when it shouldn't,
4142 * src/pic16/ralloc.c (allocReg): add preliminary support for
4143 supporting a limited set of temporary registers,
4145 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4147 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4148 genDataPointerSet): ensure assignments always copy in MSB to LSB
4150 (loadRegFromAop): recognize CLRH optimization,
4151 (genFunction): optimize RECEIVE iCodes in reentrant functions
4153 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4155 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

7153 loaded with the linker search paths (-L arguments) and the libraries
7154 to be linked with the current source (-l arguments). Changes
7155 currently will affect only the pic16 port.
7156 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7157 include path the port specific paths and port specific libraries,
7158 * gplink command now contains the $3 argument,

7176 Documenting changes from previous commits.
7177 * configure.in (version 1.56),
7178 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7179 when generating output files to configure the pic16 library,
7180 but now I've commented it out, since gputils aren't installed in the
7181 SF compile farm, so library won't compile
7183 * device/lib/Makefile.in (version 1.56): initially I've added in
7184 target 'all' the prerequestive 'model-pic16' so it compiled the
7185 pic16 library, but now I've commented it out for the same reasons
7187 * added targets 'model-pic16' and 'objects-pic16' to compile the
7189 * added target 'port-specific-objects-pic16' to handle the
7190 generated libraries and copy them into the build/ directory
7191 * added target 'clean-intermediate-pic16' to clean intermediate
7192 files into pic16 directory
7193 * in target 'installdirs' added line to create directory pic16 in

7197 added lines to copy all header files to installation path,
7198 * in target 'installdirs' added line create directory for pic16
7199 headers in the installation path

7481 * src/ds390/gen.c (genRightShift): fixed bug #870788
7482 * src/SDCCast.c (decorateType): fixed bug #870781
7484 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
7486 PIC16 port related changes:
7487 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
7488 added variable stackPos,
7490 * gen.c: genCall, assignResultValue: added support for
7491 pushing/retrieving function parameters to/from stack,
7492 genFunction,genEndFunction: setup stack frame for the
7494 genAddrOf: will be changed according to bug 863624
7496 * added files genutils.c and genutils.h which contain gen*
7497 debugged and optimised functions extracted from gen.c
7499 * glue.c: added variable 'externs' which holds extern symbols,
7500 pic16emitRegularMap: is modified to properly handle relocatable
7501 symbols under the new scheme,
7502 pic16createInterruptVect: is modified
7503 pic16printPublics: is modified to emit 'global' assembler directives,
7504 added pic16_printExterns to print extern symbols,
7505 pic16glue: initializes stack/frame pointer in the beginning of
7506 the assembly output. Temporary hack, will be corrected later,
7507 because gplink yet does not support stack and SDCC does not
7508 yet support a type of crt0.o object to create the final binary.
7510 * Removed many lines that contain 8051 legacy code.
7511 * The code is finally placed under a 'code' directive.
7512 * Added port specific options.
7514 * _process_pragma: simplified since now we do not need *special*
7515 include file to define SFR registers. But a separate header
7516 will be needed. This will be developed later.
7517 * _pic16_parseOptions: added, parses port specific options:
7518 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
7519 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
7520 --preplace-udata-with=
7522 * _pic16_setDefaultOptions: modified to initialize section names,
7523 but hack is temporarly out of order since it needs improvement.
7524 * _pic16_genAssemblerPreamble: configuration words are emitted by
7525 their address instead of their name. This part is incomplete and
7526 supports only the 18Fxx2 devices. Other devices will emit an error
7527 during assembly since they do not contain the same set of config
7529 * _pic16_genIVT: is modified,
7531 * pcode.c: added definitions for some hardware registers that are needed
7533 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
7534 All PCI entries are updated. Now LFSR is supported.
7535 * Removed pic16_pciTRIS is mentioned by mdubuc in source
7536 * added pic16_newpCodeOpLit2 to support instructions with
7537 two literal arguments
7538 * pic16_pCode2str: corrected code that emits assembler instructions
7539 with two literal operands and those that have an access bit modifier
7540 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
7541 this fixes a bug which caused some labels to be lost, when an
7542 assembler directive was added, i.e. banksel,
7543 * pic16_FixRegisterBanking: improved logic that causes the insertion
7545 * InlineFunction: functions that are called once, are not any more
7546 inlined. This can be a port option in the future,
7548 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
7550 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
7551 hold the corresponding uninitialized symbols,
7552 * pic16_allocProcessorRegister: registers have explicit marked the
7554 * pic16_allocInternalRegister: registers are explicit marked as
7556 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
7557 processing list, so bit registers were lost,
7560 * ralloc.h: added field 'accessBank' and original symbol operand
7561 in register definition,
7562 * removed the field isMapped from register definition,
7564 ** Several functions have been removed from various sources:
7565 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
7566 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
7567 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
7568 pic16_assignRelocatableRegisters
7570 ** others have been introduced:
7571 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
7572 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
7574 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
7576 * support/scripts/inc2h.pl: changed definition of BIT_AT
7577 to emit 'sbit at' instead of 'bit at'. This was a request.
7579 PIC16 port related preliminary changes:
7580 * gen.c: prefixed function popRegFromString with
7581 pic16_ and all references to it corrected
7582 * pcode.c: all pic16_pc_* hardware registers prefixed
7583 with underscore (_),
7584 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
7585 * ralloc.c: newReg(): when register is REG_SFR then
7586 set address to rIdx,
7587 pic16_allocProcessorRegister(): marks register wasUsed=0
7588 pic16_writeUsedRegs(): added a call to assign processor
7589 registers via pic16_assignFixedRegisters
7591 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
7593 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
7594 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
7595 variables in unused register banks. Also the SSEG is placed
7596 wherever there is enough space for it, and IDATA can be anywhere
7597 in internal RAM. For now compile using -Wl-Y[stack_size].
7598 The mem file is different for this option as well, since it
7599 makes no sense of talking about DSEG lenght.
7601 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
7603 * src/SDCClrange.c: fixed bug 869095 that caused segfault
7604 in certain cases, e.g. when ROM assignment, patch provided
7605 from Albert den Haan.
7607 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

7846 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7848 * src/SDCCast.c (decorateType): disabled a transformation I added in
7849 revision 1.188 (access to fields of a structure at an absolute address);
7850 it breaks with bitfields, extern declarations, and gcse analysis.
7851 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
7852 could be assigned through a pointer, so don't complain.
7853 * src/SDCCast.c (astErrors),
7855 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

8493 support for standard C idiom of memory mapped variables; for
8494 example, *((xdata int*)0x1234) = 1 is now internally equivalent
8495 to xdata int at 0x1234 tempvar = 1.
8496 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
8497 provided by Akiya ISHIDA

8513 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8515 Fixed bug #621531 (const & volatile confusion in the type chain).
8516 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
8517 refer to the const or volatile state of the pointer itself.

8608 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
8609 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
8610 fetching of the pointer
8611 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
8612 copied from genNearPointerSet()
8613 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
8614 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

8630 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8631 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
8632 type for bits was changed. It resulted in bit variables becoming
8633 global, which is not permitted in PIC 14 assembly output.
8635 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8637 * doc/sdccman.lyx: various additions and updates. Rearranged sections

8650 A few small changes that speed up the peephole optimizer.
8654 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8656 Try to make the peephole optimizer smarter by maintaining
8657 an association between the assembly source code and the
8658 iCodes that originated them. Put this information to use
8659 with a new peephole rule condition "notVolatile" so that
8660 the rules can be aggressive yet still safe.
8665 * src/mcs51/peeph.def
8667 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8671 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
8672 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
8673 if the left or right operand symbols have the accuse flag set.
8675 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8677 Changed the type of the result of the ! (NOT) operator to char;
8678 previously it returned the same type as the source. This allows
8679 us to eliminate all the genFloatNot functions (all of its target
8680 implementations were very buggy) since !float can use the same
8683 * src/SDCCicode.c (ast2iCode): ! returns char

8692 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
8693 1. Interrupt would not compile properly. Ensure PCLATH register is saved
8694 during interrupts. Ensure WSAVE is located at a shared bank address.
8695 2. Fixed page selection in some places
8696 3. Fixed BTFSS/C to where necessary use registers directly and not simply
8697 the registers name strings.
8698 4. Fixed "signed / unsigned compare" compiler warnings.
8699 5. The PIC port manages its own allocation of the general purpose
8700 registers, but makes no attempt to reuse them. As a result when
8701 compiling it soon runs out of general purpose registers. Some
8702 additional code was added to the files pcode.c and device.c to walk
8703 through the function call tree and rename the registers so that they
8713 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
8714 genPlus() & genMinus() when the result is the same as left or right

8720 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8722 Made bitfield a distinct type from bit so that bitfields
8723 convert as per ANSI C and bits retain their traditional
8724 boolean style behaviour. Implemented bitfield support in
8732 * src/ds390/gen.c: bit v bitfield split
8733 * src/z80/gen.c: New support for bitfields
8734 * support/regression/tests/bitfields.c: reenabled z80,
8737 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
8739 Rules 246.x, 247.x relate to bitfields, the others speed up
8740 access to xdata mapped I/O devices.
8742 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
8744 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8746 Cleaned up genPackBits and genUnpackBits and added two helper
8747 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
8748 for literal assignments in genPackBits (thanks to Frieder for
8754 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8756 Fixed bug #748310 (pointer to function type mishandled when the
8757 function name is omitted). Also fixed a SIGSEGV when a function
8758 attribute (reentrant, etc) is used on a non-function or on a
8759 function but misplaced before the parameter list.
8761 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
8763 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
8764 * support/Util/SDCCerr.h,
8765 * support/Util/SDCCerr.c: Added func attr misuse error msg

8786 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8788 Made the constant following the "interrupt" keyword optional. If
8789 omitted, the function will not automatically be given an entry
8790 in the interrupt vector table (similar to #pragma NOIV, but
8791 less syntacticly kludgy). The interrupt number is also now
8792 range checked. Also fixed a bug in the high order bit example

8806 * src/SDCCicode.c (operandOperation): rewritten some ops
8807 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
8808 * src/SDCCsymt.c (computeType): literals are handled the same way as any
8810 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
8811 be re-activated by defining REDUCE_LITERALS)
8812 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
8813 unsigned, but are signed by default
8814 * src/SDCCval.c (constVal): rearranged
8815 * src/SDCCval.c (valMod): preliminary fix
8816 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9321 * src/SDCCmain.c: linkOptions is changed to set *,
9322 added if/endif conditional macros to remove options help
9323 messages from optionsTable when a port is not configured, added
9324 support for the PIc16 port in the ports table, when executing
9325 the compiler with no port specified on command line, a default
9326 port is selected with the new macro DEFAULT_PORT which is
9327 defined in port.h, in setDefaultOptions() linkOptions is removed
9328 from initialization assignment, since now it is a set,
9329 parseCmdLine uses setParseWithComma for linkOptions, in
9330 linkEdit() linkOptions are accessed with new function indexSet()
9331 which returns the i'th item of a set variable. See SDCCset.c, in
9332 linkEdit() when calling buildCmdLine(), added linkOptions as
9333 last argument. Now users can pass arguments to gplink via the
9334 -Wl option, main() uses pic16glue() to glue up pic16 programs

9346 * src/pic16/glue.c: commented out some error producing lines
9347 * src/pic16/main.c: __config directives are commented out to stop
9348 gpasm complaining and test the linkage with gplink, _linkCmd and
9349 _asmCmd changed to be more gplink and gpasm friendly
9350 * src/pic16/peeph.def: peep rule 3 is commented out, since it
9351 produced an error when parsed, peep rule 12 is added to utilize
9352 movff, but it is commented out since the pCode does not support
9353 yet a command with 2 address arguments
9355 2003-05-18 <johan AT balder>
9357 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9382 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
9384 2003-05-11 Borut Razem <borut.razem AT siol.net>
9386 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
9387 the path of bin directory, so that PATH is the only env. variable, which has to be set

10390 2003-01-06 <johan AT balder>
10392 * src/SDCCicode.c: fixed array add
10394 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
10395 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
10396 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
10398 2003-01-04 <johan AT balder>
10400 * src/SDCCval.c (getNelements): fixed the initialized array of structures
10402 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10403 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
10405 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10406 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
10407 * support/regression/tests/bug-524697.c: fit mem usage into 8032
10409 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
10410 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
10412 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
10413 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
10415 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
10416 * src/mcs51/main.c: removed {bindir}{sep} from aslink
10418 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10420 * in \sdcc\as\mcs51\ changed these files in order to create an
10421 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
10422 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
10423 following files to include the previous two files: aslink.dsp,
10424 Makefile.aslink, Makefile.bcc, and Makefile.in.
10426 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
10427 .adb instead of .cdb
10429 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10431 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
10432 value from option --iram-size.
10434 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10436 * \sdcc\as\mcs51\lklist.c: added boundary check before using
10439 2002-09-18 <wiml AT hhhh.org>
10441 * SDCClrange.h: exposed setFromRange() and setToRange()
10442 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
10443 packRegsForAccUse() (bug 542397)
10444 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
10445 multiple times and emitting the fetch operations more than once
10446 added aopGetUsesAcc() function to allow binary operators to
10447 fetch their operands in the correct order; made genMinus() emit
10448 compact code for X = LITERAL - Y
10450 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10451 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
10452 sprintf() in line 1267.
10454 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10455 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
10458 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
10459 Changes to aslink (All the changes are marked with 'JCF'):
10461 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
10464 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
10465 area BSEG. Also moves, if possible, the DATA area down into the internal
10466 ram so more space is available.
10468 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
10471 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
10472 not bytes. Function summary() which creates a memory usage summary
10473 file with extension .mem. Reports of overlaping stack and small stack
10474 size. If the space for the stack is less than 16 bytes aslink trows a
10477 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
10478 the 8051. Option 'y' for memory summary output file.
10480 Changes to sdcc (All the changes are marked with 'JCF'):
10482 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
10484 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
10485 overlaying area for it (uses RegBankUsed[4]).
10487 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
10488 bank zero as used by default. By default aslink locates the stack
10489 (equivalent to --stack-after-data). Pass option 'y' to aslink for
10490 the creation of the .mem file. Delegates the allocation of data area
10491 to aslink (it is not longer 0x30 by default). If --stack-loc passes
10492 the begining of the stack area to aslink.
10494 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
10495 glue() in SDCCglue.c creates an area for it.
10497 2002-09-03 Borut Razem <borut.razem AT siol.net>
10498 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
10499 sdcc/src/pic/glue.c:
10500 introduced atexit() handler for teporay files removal in case of
10501 errors, assertions, ...
10503 2002-08-29 Borut Razem <borut.razem AT siol.net>
10504 * sdcc/support/cpp2/auto-host_vc_in.h:
10505 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
10506 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
10507 Maybe there is a similar problem with BORLANDC? It should be checked!
10509 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
10510 corrected improper use of assert: the assignment to clr variable was done inside the assert.
10511 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10512 was not executed, and the compiler (cl) launched a warning:
10513 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
10515 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
10516 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
10518 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
10519 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
10521 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10522 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
10523 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
10524 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10525 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
10526 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
10527 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
10528 - added Release configuration in VS projects
10529 - review of compiler an linker options
10530 - VC .exe files are generated in bin_vc directory, not to interfere
10531 with binaries generated from other projects (cygwin, mingw, bcc ...)
10533 * sdcc/src/yacc.dsp: added
10535 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
10536 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
10537 and insert the version number definitions from .version
10539 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
10541 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
10542 added - genarate auto-host.h using auto-host_vc_in.h as template
10545 removed from CVS, generated automatically
10547 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
10548 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
10550 2002-08-11 Borut Razem <borut.razem AT siol.net>
10551 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
10553 2002-08-10 Borut Razem <borut.razem AT siol.net>
10554 * src/SDCCmain.c (main):
10555 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
10556 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
10557 The consequence was that some temporary files were not removed.
10560 unification of code in functions tempfilename() and tempfile():
10561 function tempnam() is defined in Visual Studio 6.0 and .NET
10563 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
10565 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
10566 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
10567 - removed compiler command line option /WX: Treats all warnings as errors
10568 - update a list of source files, included into the project
10570 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
10571 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
10572 changed project type to Generic Project so that can be correcly converted to VS.NET project
10574 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
10576 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
10578 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
10580 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
10581 added return 0 statements after assert() to make compiler happy
10583 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
10584 added newline in the def file to keep MSC compiler satisfied
10586 * sdcc/src/z80/gen.c:
10587 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
10588 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
10589 - solved MSC error in function aopDump()
10591 * sdcc_vc.h: define PREFIX as "\\sdcc"
10593 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
10594 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

10597 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
10598 - Rewrote the register banking algorithm.
10599 - Added pCode live-range analysis to registers (for now, only non-used and
10600 singly-used registers optimized away)

10631 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
10633 2002-03-28 Johan Knol <johan AT balder>
10635 * src/SDCCval.c: fixed bug #532436
10637 2002-03-14 Scott Dattalo <scott AT dattalo.com>
10639 Added "char *Processor" field to the port structure.
10642 Added -p option. Allows port dependent processor to be specified.
10645 Initialized the new field char *Processor field to NULL in all ports
10648 Compiler generated registers for interrupt context saving
10649 were not getting allocated.
10651 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
10654 Fixed left shift. Will promote the left side of a left shift
10655 if a) left shifting more than size of operand or b) when assigned
10656 to something size > size of left side
10658 2002-03-14 Scott Dattalo <scott AT dattalo.com>

10662 analysis is restructured. ...
10664 * src/pic/device.h:
10667 * src/pic/device.c:
10668 Added. device.c is a PIC port hack to accomodate variations
10671 2002-03-13 Michael Hope <michaelh AT vroom>
10673 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
10675 2002-03-04 johanknol <johanknol AT manik>
10677 * /src/SDCCval.c: fixed

10766 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
10768 * sdcc/src/SDCCloop.c:
10769 Previous fix was not good. basic blocks that have "break" or "return" are
10770 not really partof a loop , but live ranges used in these blocks should
10771 be live thru the entire loop, so set partOfLoop but don't add them to
10774 2002-02-21 <johan AT FRIJA>
10776 * src/SDCCcse.c: fixed bug #514308
10778 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
10781 Fixed BUG #519583. If a conditional block ended in a return/break
10782 statement inside a loop, it was not being considered part of the loop.
10784 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
10786 2002-02-10 Karl Bongers <karl AT turbobit.com>

10803 Karl and Johan start ucsim XA support. Most dissassembly working,
10804 about 75% emulation done(plenty of work remaining).
10806 * sim/ucsim/z80.src:
10807 Add Z80 support to ucsim, add test-ucz80 regression test,
10808 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
10809 Notice z80 compiler fails on examples/test3.c/crc code.
10811 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>

10825 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
10826 1) handle multiple send & receives from register bank1
10827 2) ralloc can now allocate DPTR1 to some liveRanges
10829 * src/SDCCsymt.c, src/SDCCsymt.h:
10830 changes to handle multiple sends & receives
10832 * src/SDCCptropt.h:
10833 added some pointer arithmetic optimization
10835 * src/SDCCptropt.c:
