1478 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1480 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1481 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1483 One basic decision: e.g. src/clean.mk includes further files. In order
1484 to make this work there are two solutions:
1485 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1486 run configure on them. This way they can use
1487 'include $(srcdir)/port-clean.mk'
1488 - always include clean.mk by the Makefile at the same level. To avoid
1489 that `make clean` tries to include and build Makefile.dep the
1490 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1491 implemented, because now even `make uninstall` doesn't create
1492 Makefile.in. clean.mk could be eliminated by pasting it in
1495 * debugger/mcs51/Makefile.in: build own objects from library sources
1496 (SLIB, SDCC) in current directory
1498 * configure, configure.in: renamed --disable-device-lib-build in
1499 --disable-device-lib; added --enable-doc, the required tools are
1500 searched by configure; added result message; the toolchain for the
1501 belonging ports are now only built, if the port is enabled.
1503 * support/regression/*: all output is written in directory gen, because
1504 the fwk and ports directories don't livet in the build tree using vpath
1506 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1507 --disable-device-lib, added --enable-doc, added section VPATH
1509 * sim/ucsim/configure.in,
1510 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1511 z80 are enabled by default
1513 2006-04-24 Raphael Neider <rneider AT web.de>
1515 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1516 to config word, "pic14_"-prefixed some extern functions
1517 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1518 config word has been found
1519 * src/pic/device.h: added prototypes
1520 * src/pic/pcode.c: added "pic14_"-prefix where needed
1521 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1523 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1538 (pCodeRegOptimizeRegUsage): fixed typo in comment

1796 archive with gcc 4.1 on mips and wrote the patch"
1798 2006-03-16 Raphael Neider <rneider AT web.de>
1800 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1801 the left operand is shorter than the result (c* = lit-c* + int),
1803 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1806 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1808 * src/.version: increased version number to 2.5.5
1809 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1810 linking is done manually in pic16 port's _linkEdit,
1811 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1812 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1813 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1814 allocate asmop as AOP_ACC,
1815 (aopForRemat): added parameter 'bool result' in function declaration,
1816 (pic16_aopGet): return AOP_ACC when accessing WREG,
1817 (pic16_popGetTempReg): minor modification,
1818 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1819 'pic16_allocWithIdx',

1826 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1828 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1829 call to allocReg, not by manually allocating a new one,
1830 (pic16_assignRegisters): now before going through the register
1831 allocating functions mark all registers as free. This eliminates some
1832 side effects resulting from peephole parser done earlier in the backbone
1834 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1855 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1856 (aopForSym, aopOp): increment asmop.allocated if reused,
1857 (freeAsmop): decrement asmop.allocated and check for zero instead of
1859 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,

1887 made the linker quiet
1889 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>

1892 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1893 which dumps before the function entry point a data byte which represents
1894 the number of the local variables used by the specified function, added
1895 'xinst' for initial support for Extended Instruction Support,
1896 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1897 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1898 port->fun_prefix anymore (may change later),
1899 (genFunction, genEndFunction): do not store/restore local registers for
1900 _main (this should take care the --main-return command line option in
1902 (genOr): removed some legacy pic-port instructions,
1903 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1904 performing operations with SFR's causes data to be written more than
1905 once to each SFR. Perhaps SFRs should be handled in special cases...
1906 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1908 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1909 into account for stack starting position,

1911 --extended or -y for Extended Instruction Support,
1912 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1913 (deassignLRs): *** perhaps the most important change, old 'for' code
1914 (commented out for reference), didn't account for some registers which
1915 were left marked 'not free' after a pointer operation. The change
1916 reduces register usage a lot in some cases

4274 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4276 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4278 * device/lib/printf_large.c: removed inline assembly for portability and
4279 readability. Use printf_fast if speed or size are more important.
4280 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4281 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4283 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4285 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4286 prevent compiler warning
4288 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4290 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4291 moved to level 0 and declared as static. Also they are explicit
4292 placed in access bank. This was necessery because some times they
4293 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4294 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4295 optimizations. Currently only compare to unsigned char is implemented,
4296 * src/pic16/gen.c: added fReturnIdx array,
4297 * (struct resolvedIfx) is moved to gen.h and made public,
4298 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4299 * (aopForSym): added an optimization to directly store in stack of
4300 the operand of a SEND iCode,
4301 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4302 but as registers instead (AOP_REG) using the fReturnIdx array,
4303 * (pic16_freeAsmop): remove the freed register from the
4304 _G.sregsAlloc field,
4305 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4306 a compare of 'WREG',
4307 * (pic16_popGetTempRegCond): changed function prototype, now
4308 function takes also a bitVector argument v which holds the current
4309 set of registers that are allocated for stack access by aopForSym,
4310 registers allocated in aopForSym for accessing stack symbols are not
4311 any more part of the functions usedRegs field,
4312 * (genCall): some times aopOp is called for a stack variable to be
4313 send, aopForSym might perform the push, if this is true make sure
4314 that genCall doesn't push the variable twice by testing _G.resDirect,
4315 * (genFunction): changed testing for unspecified interrupt number
4316 from 256 to INTNO_UNSPEC,
4317 * modified selection scheme of frame pointer generation. Previously
4318 if function did use local registers a frame pointer was generated,
4319 now a frame pointer is generated only if function has arguments
4320 (that need PLUSW2 register access), or has stack arguments, or the
4321 compiler is not instructed to omit the frame pointer,
4322 * (genEndFunction): before restoring local registers that were saved
4323 in the function preamble, also restore the registers that *might*
4324 have been allocated for stack access,
4325 * (genRet): removed some old comments,
4326 * (genCmp, the active (RN's) version): added a call to the
4327 pic16_genCmp_special function to perform the compare with a more
4328 robust and optimized way,
4329 * (genInline): a feature has been added in inline code generation,
4330 which allows a wildcard variable substitution when writing inline
4331 assembly. Code is incomplete and experimental therefore undocumented,
4332 * (genCast): changed order of aopOp for result and right to allow
4333 aopForSym to directly load the result if possible,
4334 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4335 perform an optimized compare on some selected special occasions,

4353 is not used currently,
4354 * (pic16_packRegisters): added an optimization while reading
4355 structure bitfields, some registers may be saved (malloc code is
4356 decreased by 80 bytes)

5000 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
5002 Adding support for replacing ljmps with sjmps in jumptables
5003 generated for switch statements. For now you need to set the
5004 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5005 Now 4 algorithms for mcs51 jumptable generation are used:
5006 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5007 addresses loaded pc-relative for up to 112 cases and stack-pushing
5008 target addresses loaded with offset from dptr for up to 256 cases.

5040 * added libc directory. The current version of LibC contains string
5041 functions, ctype functions and macros and some functions of the
5042 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5043 be extensively tested in the future. Standard disclaimer here.

5056 * (pic16_storeForReturn): optimized return of 0,
5057 * (genCmp): experimental code for new genCmp which uses PIC18's
5058 special compare&skip instructions. Initial tests fail some times
5059 with variables grater than 1 byte in size, so new code is disabled,
5060 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5062 * (genCast): began a fix to optimize the casting of a bit to another
5063 bit, now assigning a bitfield to another bitfield will fail, sorry,

5072 and 1 for banking instruction,
5073 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5074 caused stop processing pCodes after a inline assembly block,
5075 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5077 registers when it shouldn't,
5078 * src/pic16/ralloc.c (allocReg): add preliminary support for
5079 supporting a limited set of temporary registers,
5081 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5087 (genFunction): optimize RECEIVE iCodes in reentrant functions
5089 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8089 loaded with the linker search paths (-L arguments) and the libraries
8090 to be linked with the current source (-l arguments). Changes
8091 currently will affect only the pic16 port.
8092 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8093 include path the port specific paths and port specific libraries,
8094 * gplink command now contains the $3 argument,
8095 * src/pic16/device.h,
8096 * src/pic16/device.c,: structure PIC_device is made public and

8112 Documenting changes from previous commits.
8113 * configure.in (version 1.56),
8114 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8115 when generating output files to configure the pic16 library,
8116 but now I've commented it out, since gputils aren't installed in the
8117 SF compile farm, so library won't compile
8119 * device/lib/Makefile.in (version 1.56): initially I've added in
8120 target 'all' the prerequestive 'model-pic16' so it compiled the
8121 pic16 library, but now I've commented it out for the same reasons
8123 * added targets 'model-pic16' and 'objects-pic16' to compile the
8125 * added target 'port-specific-objects-pic16' to handle the
8126 generated libraries and copy them into the build/ directory
8127 * added target 'clean-intermediate-pic16' to clean intermediate
8128 files into pic16 directory
8129 * in target 'installdirs' added line to create directory pic16 in

8340 arguments via -W option
8341 * src/pic16/main.c: added $l in _asmCmd, changed extension for
8342 object file from '.rel' to '.o' in port->linker structure,
8343 changed size of fptr from 2 to 3 in port structure
8345 2004-01-07 Borut Razem <borut.razem AT siol.net>
8347 * support/scripts/sdcc.nsi: update PATH

8374 * src/SDCCast.c (decorateType),
8375 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
8376 LEFT_OP (left shift)
8378 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8380 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8381 (default behaviour).
8383 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8385 A python script to validate compiler diagnostic messages. It can be
8386 used to verify that sdcc complains about bad c source code and
8387 gives a good location of the error.
8388 * support/valdiag/Makefile,
8389 * support/valdiag/valdiag.py,
8390 * support/valdiag/tests/*
8392 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8405 * src/common.h: added ifndef/define/endif macros
8406 around the header file.
8407 Bug reported from Jesus Calvino-Fraga
8409 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8411 * sdcc.spec: updated
8412 * device/include/Makefile.in: don't install CVS directories
8413 * device/lib/Makefile.in: added removal of CVS directories after install
8414 * doc/Makefile: fixed install, added local_icons
8415 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8416 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8417 * src/ds390/gen.c (genRightShift): fixed bug #870788
8418 * src/SDCCast.c (decorateType): fixed bug #870781
8420 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8422 PIC16 port related changes:
8423 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8424 added variable stackPos,
8426 * gen.c: genCall, assignResultValue: added support for
8427 pushing/retrieving function parameters to/from stack,
8428 genFunction,genEndFunction: setup stack frame for the
8430 genAddrOf: will be changed according to bug 863624
8432 * added files genutils.c and genutils.h which contain gen*
8433 debugged and optimised functions extracted from gen.c
8435 * glue.c: added variable 'externs' which holds extern symbols,
8436 pic16emitRegularMap: is modified to properly handle relocatable
8437 symbols under the new scheme,
8438 pic16createInterruptVect: is modified
8439 pic16printPublics: is modified to emit 'global' assembler directives,
8440 added pic16_printExterns to print extern symbols,
8441 pic16glue: initializes stack/frame pointer in the beginning of
8442 the assembly output. Temporary hack, will be corrected later,
8443 because gplink yet does not support stack and SDCC does not
8444 yet support a type of crt0.o object to create the final binary.
8446 * Removed many lines that contain 8051 legacy code.
8447 * The code is finally placed under a 'code' directive.
8448 * Added port specific options.
8450 * _process_pragma: simplified since now we do not need *special*
8451 include file to define SFR registers. But a separate header
8452 will be needed. This will be developed later.
8453 * _pic16_parseOptions: added, parses port specific options:
8454 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8455 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8456 --preplace-udata-with=
8458 * _pic16_setDefaultOptions: modified to initialize section names,
8459 but hack is temporarly out of order since it needs improvement.
8460 * _pic16_genAssemblerPreamble: configuration words are emitted by
8461 their address instead of their name. This part is incomplete and
8462 supports only the 18Fxx2 devices. Other devices will emit an error
8463 during assembly since they do not contain the same set of config
8465 * _pic16_genIVT: is modified,
8467 * pcode.c: added definitions for some hardware registers that are needed
8469 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8470 All PCI entries are updated. Now LFSR is supported.
8471 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8472 * added pic16_newpCodeOpLit2 to support instructions with
8473 two literal arguments
8474 * pic16_pCode2str: corrected code that emits assembler instructions
8475 with two literal operands and those that have an access bit modifier
8476 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8477 this fixes a bug which caused some labels to be lost, when an
8478 assembler directive was added, i.e. banksel,
8479 * pic16_FixRegisterBanking: improved logic that causes the insertion
8481 * InlineFunction: functions that are called once, are not any more
8482 inlined. This can be a port option in the future,
8484 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8486 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8487 hold the corresponding uninitialized symbols,
8488 * pic16_allocProcessorRegister: registers have explicit marked the
8490 * pic16_allocInternalRegister: registers are explicit marked as
8492 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8493 processing list, so bit registers were lost,
8496 * ralloc.h: added field 'accessBank' and original symbol operand
8497 in register definition,
8498 * removed the field isMapped from register definition,
8500 ** Several functions have been removed from various sources:
8501 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8502 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8503 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8504 pic16_assignRelocatableRegisters
8506 ** others have been introduced:
8507 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8508 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8510 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8512 * support/scripts/inc2h.pl: changed definition of BIT_AT
8513 to emit 'sbit at' instead of 'bit at'. This was a request.
8515 PIC16 port related preliminary changes:
8516 * gen.c: prefixed function popRegFromString with
8517 pic16_ and all references to it corrected
8518 * pcode.c: all pic16_pc_* hardware registers prefixed
8519 with underscore (_),
8520 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8521 * ralloc.c: newReg(): when register is REG_SFR then
8522 set address to rIdx,
8523 pic16_allocProcessorRegister(): marks register wasUsed=0
8524 pic16_writeUsedRegs(): added a call to assign processor
8525 registers via pic16_assignFixedRegisters
8527 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8529 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8530 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8531 variables in unused register banks. Also the SSEG is placed
8532 wherever there is enough space for it, and IDATA can be anywhere
8533 in internal RAM. For now compile using -Wl-Y[stack_size].
8534 The mem file is different for this option as well, since it
8535 makes no sense of talking about DSEG lenght.
8537 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8539 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8540 in certain cases, e.g. when ROM assignment, patch provided
8541 from Albert den Haan.

8782 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8784 * src/SDCCast.c (decorateType): disabled a transformation I added in
8785 revision 1.188 (access to fields of a structure at an absolute address);
8786 it breaks with bitfields, extern declarations, and gcse analysis.
8787 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8788 could be assigned through a pointer, so don't complain.

9428 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
9429 support for standard C idiom of memory mapped variables; for
9430 example, *((xdata int*)0x1234) = 1 is now internally equivalent
9431 to xdata int at 0x1234 tempvar = 1.
9432 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
9433 provided by Akiya ISHIDA

9449 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9451 Fixed bug #621531 (const & volatile confusion in the type chain).
9452 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

9544 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9545 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9546 fetching of the pointer
9547 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9548 copied from genNearPointerSet()
9549 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9550 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9551 If they pop r0/r1 they must be called in the opposite order than aopOp().
9552 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9553 (resp. --stack-auto), prepared for --xstack

9564 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9566 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9567 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9568 type for bits was changed. It resulted in bit variables becoming
9569 global, which is not permitted in PIC 14 assembly output.
9571 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9586 A few small changes that speed up the peephole optimizer.
9590 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9592 Try to make the peephole optimizer smarter by maintaining
9593 an association between the assembly source code and the
9594 iCodes that originated them. Put this information to use
9595 with a new peephole rule condition "notVolatile" so that
9596 the rules can be aggressive yet still safe.
9601 * src/mcs51/peeph.def
9603 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9607 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9608 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9609 if the left or right operand symbols have the accuse flag set.
9611 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9613 Changed the type of the result of the ! (NOT) operator to char;
9614 previously it returned the same type as the source. This allows
9615 us to eliminate all the genFloatNot functions (all of its target
9616 implementations were very buggy) since !float can use the same
9619 * src/SDCCicode.c (ast2iCode): ! returns char

9628 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9629 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9630 during interrupts. Ensure WSAVE is located at a shared bank address.
9631 2. Fixed page selection in some places
9632 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9633 the registers name strings.
9634 4. Fixed "signed / unsigned compare" compiler warnings.
9635 5. The PIC port manages its own allocation of the general purpose
9636 registers, but makes no attempt to reuse them. As a result when
9637 compiling it soon runs out of general purpose registers. Some
9638 additional code was added to the files pcode.c and device.c to walk
9639 through the function call tree and rename the registers so that they
9649 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9650 genPlus() & genMinus() when the result is the same as left or right
9652 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9656 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9658 Made bitfield a distinct type from bit so that bitfields
9659 convert as per ANSI C and bits retain their traditional
9660 boolean style behaviour. Implemented bitfield support in
9668 * src/ds390/gen.c: bit v bitfield split
9669 * src/z80/gen.c: New support for bitfields
9670 * support/regression/tests/bitfields.c: reenabled z80,
9673 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9675 Rules 246.x, 247.x relate to bitfields, the others speed up
9676 access to xdata mapped I/O devices.
9678 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9680 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9682 Cleaned up genPackBits and genUnpackBits and added two helper
9683 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9684 for literal assignments in genPackBits (thanks to Frieder for
9690 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9692 Fixed bug #748310 (pointer to function type mishandled when the
9693 function name is omitted). Also fixed a SIGSEGV when a function
9694 attribute (reentrant, etc) is used on a non-function or on a
9695 function but misplaced before the parameter list.
9697 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9699 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9700 * support/Util/SDCCerr.h,

9722 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9724 Made the constant following the "interrupt" keyword optional. If
9725 omitted, the function will not automatically be given an entry
9726 in the interrupt vector table (similar to #pragma NOIV, but
9727 less syntacticly kludgy). The interrupt number is also now
9728 range checked. Also fixed a bug in the high order bit example

9744 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9746 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9747 be re-activated by defining REDUCE_LITERALS)
9748 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9749 unsigned, but are signed by default
9750 * src/SDCCval.c (constVal): rearranged
9751 * src/SDCCval.c (valMod): preliminary fix
9752 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9794 constants are unsigned; added recognition of "u" flag for unsigned
9795 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9796 * src/SDCCval.c (valDiv, valMod): fixed signdness
9797 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed

10259 messages from optionsTable when a port is not configured, added
10260 support for the PIc16 port in the ports table, when executing
10261 the compiler with no port specified on command line, a default
10262 port is selected with the new macro DEFAULT_PORT which is
10263 defined in port.h, in setDefaultOptions() linkOptions is removed
10264 from initialization assignment, since now it is a set,
10265 parseCmdLine uses setParseWithComma for linkOptions, in
10266 linkEdit() linkOptions are accessed with new function indexSet()
10267 which returns the i'th item of a set variable. See SDCCset.c, in
10268 linkEdit() when calling buildCmdLine(), added linkOptions as
10269 last argument. Now users can pass arguments to gplink via the
10270 -Wl option, main() uses pic16glue() to glue up pic16 programs

10284 gpasm complaining and test the linkage with gplink, _linkCmd and
10285 _asmCmd changed to be more gplink and gpasm friendly
10286 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10287 produced an error when parsed, peep rule 12 is added to utilize
10288 movff, but it is commented out since the pCode does not support
10289 yet a command with 2 address arguments
10291 2003-05-18 <johan AT balder>
10293 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11341 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11342 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11348 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11349 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11351 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11352 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11354 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11356 * in /sdcc/as/mcs51/ changed these files in order to create an
11357 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11358 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11359 following files to include the previous two files: aslink.dsp,
11360 Makefile.aslink, Makefile.bcc, and Makefile.in.
11362 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11363 .adb instead of .cdb
11365 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11367 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11368 value from option --iram-size.
11370 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11372 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11375 2002-09-18 <wiml AT hhhh.org>
11377 * SDCClrange.h: exposed setFromRange() and setToRange()
11378 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11379 packRegsForAccUse() (bug 542397)
11380 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11381 multiple times and emitting the fetch operations more than once
11382 added aopGetUsesAcc() function to allow binary operators to
11383 fetch their operands in the correct order; made genMinus() emit
11384 compact code for X = LITERAL - Y
11386 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11387 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11388 sprintf() in line 1267.
11390 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11391 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11394 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11395 Changes to aslink (All the changes are marked with 'JCF'):
11397 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11400 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11401 area BSEG. Also moves, if possible, the DATA area down into the internal
11402 ram so more space is available.
11404 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11407 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11408 not bytes. Function summary() which creates a memory usage summary
11409 file with extension .mem. Reports of overlaping stack and small stack
11410 size. If the space for the stack is less than 16 bytes aslink trows a
11413 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11414 the 8051. Option 'y' for memory summary output file.
11416 Changes to sdcc (All the changes are marked with 'JCF'):
11418 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11420 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11421 overlaying area for it (uses RegBankUsed[4]).
11423 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11424 bank zero as used by default. By default aslink locates the stack
11425 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11426 the creation of the .mem file. Delegates the allocation of data area
11427 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11428 the begining of the stack area to aslink.
11430 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11431 glue() in SDCCglue.c creates an area for it.
11433 2002-09-03 Borut Razem <borut.razem AT siol.net>
11434 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11435 sdcc/src/pic/glue.c:
11436 introduced atexit() handler for teporay files removal in case of
11437 errors, assertions, ...
11439 2002-08-29 Borut Razem <borut.razem AT siol.net>
11440 * sdcc/support/cpp2/auto-host_vc_in.h:
11441 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11442 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11443 Maybe there is a similar problem with BORLANDC? It should be checked!
11445 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11446 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11447 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11448 was not executed, and the compiler (cl) launched a warning:
11449 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11451 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11452 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11454 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11455 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11457 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11458 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11459 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11460 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11461 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11462 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11463 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11464 - added Release configuration in VS projects
11465 - review of compiler an linker options
11466 - VC .exe files are generated in bin_vc directory, not to interfere
11467 with binaries generated from other projects (cygwin, mingw, bcc ...)
11469 * sdcc/src/yacc.dsp: added
11471 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11472 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11473 and insert the version number definitions from .version
11475 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11477 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11478 added - genarate auto-host.h using auto-host_vc_in.h as template
11481 removed from CVS, generated automatically
11483 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11484 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11486 2002-08-11 Borut Razem <borut.razem AT siol.net>
11487 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11489 2002-08-10 Borut Razem <borut.razem AT siol.net>
11490 * src/SDCCmain.c (main):
11491 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11492 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11493 The consequence was that some temporary files were not removed.
11496 unification of code in functions tempfilename() and tempfile():
11497 function tempnam() is defined in Visual Studio 6.0 and .NET
11499 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11501 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11502 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11503 - removed compiler command line option /WX: Treats all warnings as errors
11504 - update a list of source files, included into the project
11506 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11507 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11508 changed project type to Generic Project so that can be correcly converted to VS.NET project
11510 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11512 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11514 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11516 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11517 added return 0 statements after assert() to make compiler happy
11519 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11520 added newline in the def file to keep MSC compiler satisfied
11522 * sdcc/src/z80/gen.c:
11523 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11524 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11525 - solved MSC error in function aopDump()
11527 * sdcc_vc.h: define PREFIX as "\\sdcc"
11529 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11530 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11533 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11534 - Rewrote the register banking algorithm.
11535 - Added pCode live-range analysis to registers (for now, only non-used and
11536 singly-used registers optimized away)
11538 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11540 * 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.

11567 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11569 2002-03-28 Johan Knol <johan AT balder>
11571 * src/SDCCval.c: fixed bug #532436
11573 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11575 Added "char *Processor" field to the port structure.
11578 Added -p option. Allows port dependent processor to be specified.
11581 Initialized the new field char *Processor field to NULL in all ports
11584 Compiler generated registers for interrupt context saving
11585 were not getting allocated.
11587 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11590 Fixed left shift. Will promote the left side of a left shift
11591 if a) left shifting more than size of operand or b) when assigned
11592 to something size > size of left side
11594 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11596 tons of changes. Register allocation has been
11597 rewritten. Added customization for the various PICs. Flow
11598 analysis is restructured. ...
11600 * src/pic/device.h:
11603 * src/pic/device.c:
11604 Added. device.c is a PIC port hack to accomodate variations
11607 2002-03-13 Michael Hope <michaelh AT vroom>
11609 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11611 2002-03-04 johanknol <johanknol AT manik>
11613 * /src/SDCCval.c: fixed
11615 const unsigned char arr[][2] = { { 0, 1 } };
11616 t18.c:1: error: Initializer element is not constant
11618 2002-03-04 bela <bela AT manik>
