1473 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1475 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1476 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1478 One basic decision: e.g. src/clean.mk includes further files. In order
1479 to make this work there are two solutions:
1480 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1481 run configure on them. This way they can use
1482 'include $(srcdir)/port-clean.mk'
1483 - always include clean.mk by the Makefile at the same level. To avoid
1484 that `make clean` tries to include and build Makefile.dep the
1485 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1486 implemented, because now even `make uninstall` doesn't create
1487 Makefile.in. clean.mk could be eliminated by pasting it in
1490 * debugger/mcs51/Makefile.in: build own objects from library sources
1491 (SLIB, SDCC) in current directory
1493 * configure, configure.in: renamed --disable-device-lib-build in
1494 --disable-device-lib; added --enable-doc, the required tools are
1495 searched by configure; added result message; the toolchain for the
1496 belonging ports are now only built, if the port is enabled.
1498 * support/regression/*: all output is written in directory gen, because
1499 the fwk and ports directories don't livet in the build tree using vpath
1501 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1502 --disable-device-lib, added --enable-doc, added section VPATH
1504 * sim/ucsim/configure.in,
1505 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1506 z80 are enabled by default
1508 2006-04-24 Raphael Neider <rneider AT web.de>
1510 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1511 to config word, "pic14_"-prefixed some extern functions
1512 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1513 config word has been found
1514 * src/pic/device.h: added prototypes
1515 * src/pic/pcode.c: added "pic14_"-prefix where needed

1790 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1791 archive with gcc 4.1 on mips and wrote the patch"
1793 2006-03-16 Raphael Neider <rneider AT web.de>
1795 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1796 the left operand is shorter than the result (c* = lit-c* + int),
1798 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1801 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1803 * src/.version: increased version number to 2.5.5
1804 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1805 linking is done manually in pic16 port's _linkEdit,
1806 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1807 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1808 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1809 allocate asmop as AOP_ACC,
1810 (aopForRemat): added parameter 'bool result' in function declaration,
1811 (pic16_aopGet): return AOP_ACC when accessing WREG,
1812 (pic16_popGetTempReg): minor modification,
1813 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1814 'pic16_allocWithIdx',
1815 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1816 calling function in absolute addresses,
1817 (genAssign): take into account AOP_ACC asmop,
1818 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1819 * src/pic16/pcoderegs.c: some debug functions and lines added,
1820 * src/pic16/ralloc.c (decodeRegType): added but commented out,
1821 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1823 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1824 call to allocReg, not by manually allocating a new one,
1825 (pic16_assignRegisters): now before going through the register
1826 allocating functions mark all registers as free. This eliminates some
1827 side effects resulting from peephole parser done earlier in the backbone
1829 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1831 * src/SDCCicode.c (geniCodeLogic),

1849 * src/mcs51/gen.h: changed asmop.freed:1 to asmop.allocated for tracking
1850 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1851 (aopForSym, aopOp): increment asmop.allocated if reused,
1852 (freeAsmop): decrement asmop.allocated and check for zero instead of
1854 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1855 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1856 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1879 2006-03-06 Borut Razem <borut.razem AT siol.net>
1881 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1882 made the linker quiet
1884 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1886 * src/pic16/gen.c (genPcall): fixed bug #1443644
1887 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1888 which dumps before the function entry point a data byte which represents
1889 the number of the local variables used by the specified function, added
1890 'xinst' for initial support for Extended Instruction Support,
1891 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1892 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1893 port->fun_prefix anymore (may change later),
1894 (genFunction, genEndFunction): do not store/restore local registers for
1895 _main (this should take care the --main-return command line option in
1897 (genOr): removed some legacy pic-port instructions,
1898 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1899 performing operations with SFR's causes data to be written more than
1900 once to each SFR. Perhaps SFRs should be handled in special cases...
1901 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1903 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1904 into account for stack starting position,
1905 (struct OPTIONS pic16_optionsTable): added command line argument
1906 --extended or -y for Extended Instruction Support,
1907 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1908 (deassignLRs): *** perhaps the most important change, old 'for' code
1909 (commented out for reference), didn't account for some registers which
1910 were left marked 'not free' after a pointer operation. The change
1911 reduces register usage a lot in some cases

4269 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4271 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4273 * device/lib/printf_large.c: removed inline assembly for portability and
4274 readability. Use printf_fast if speed or size are more important.
4275 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4276 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4278 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4280 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4281 prevent compiler warning
4283 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4285 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4286 moved to level 0 and declared as static. Also they are explicit
4287 placed in access bank. This was necessery because some times they
4288 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4289 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4290 optimizations. Currently only compare to unsigned char is implemented,
4291 * src/pic16/gen.c: added fReturnIdx array,
4292 * (struct resolvedIfx) is moved to gen.h and made public,
4293 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4294 * (aopForSym): added an optimization to directly store in stack of
4295 the operand of a SEND iCode,
4296 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4297 but as registers instead (AOP_REG) using the fReturnIdx array,
4298 * (pic16_freeAsmop): remove the freed register from the
4299 _G.sregsAlloc field,
4300 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4301 a compare of 'WREG',
4302 * (pic16_popGetTempRegCond): changed function prototype, now
4303 function takes also a bitVector argument v which holds the current
4304 set of registers that are allocated for stack access by aopForSym,
4305 registers allocated in aopForSym for accessing stack symbols are not
4306 any more part of the functions usedRegs field,
4307 * (genCall): some times aopOp is called for a stack variable to be
4308 send, aopForSym might perform the push, if this is true make sure
4309 that genCall doesn't push the variable twice by testing _G.resDirect,
4310 * (genFunction): changed testing for unspecified interrupt number
4311 from 256 to INTNO_UNSPEC,
4312 * modified selection scheme of frame pointer generation. Previously
4313 if function did use local registers a frame pointer was generated,
4314 now a frame pointer is generated only if function has arguments
4315 (that need PLUSW2 register access), or has stack arguments, or the
4316 compiler is not instructed to omit the frame pointer,
4317 * (genEndFunction): before restoring local registers that were saved
4318 in the function preamble, also restore the registers that *might*
4319 have been allocated for stack access,
4320 * (genRet): removed some old comments,

4322 pic16_genCmp_special function to perform the compare with a more
4323 robust and optimized way,
4324 * (genInline): a feature has been added in inline code generation,
4325 which allows a wildcard variable substitution when writing inline
4326 assembly. Code is incomplete and experimental therefore undocumented,
4327 * (genCast): changed order of aopOp for result and right to allow
4328 aopForSym to directly load the result if possible,

4997 Adding support for replacing ljmps with sjmps in jumptables
4998 generated for switch statements. For now you need to set the
4999 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5000 Now 4 algorithms for mcs51 jumptable generation are used:
5001 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5002 addresses loaded pc-relative for up to 112 cases and stack-pushing
5003 target addresses loaded with offset from dptr for up to 256 cases.

5035 * added libc directory. The current version of LibC contains string
5036 functions, ctype functions and macros and some functions of the
5037 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5038 be extensively tested in the future. Standard disclaimer here.
5039 Library is not automatically build yet. But one can build it by

5051 * (pic16_storeForReturn): optimized return of 0,
5052 * (genCmp): experimental code for new genCmp which uses PIC18's
5053 special compare&skip instructions. Initial tests fail some times
5054 with variables grater than 1 byte in size, so new code is disabled,
5055 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5057 * (genCast): began a fix to optimize the casting of a bit to another
5058 bit, now assigning a bitfield to another bitfield will fail, sorry,

5067 and 1 for banking instruction,
5068 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5069 caused stop processing pCodes after a inline assembly block,
5070 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5072 registers when it shouldn't,
5073 * src/pic16/ralloc.c (allocReg): add preliminary support for
5074 supporting a limited set of temporary registers,

8084 loaded with the linker search paths (-L arguments) and the libraries
8085 to be linked with the current source (-l arguments). Changes
8086 currently will affect only the pic16 port.
8087 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8088 include path the port specific paths and port specific libraries,
8089 * gplink command now contains the $3 argument,
8090 * src/pic16/device.h,

8107 Documenting changes from previous commits.
8108 * configure.in (version 1.56),
8109 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8110 when generating output files to configure the pic16 library,
8111 but now I've commented it out, since gputils aren't installed in the
8112 SF compile farm, so library won't compile
8114 * device/lib/Makefile.in (version 1.56): initially I've added in
8115 target 'all' the prerequestive 'model-pic16' so it compiled the
8116 pic16 library, but now I've commented it out for the same reasons
8118 * added targets 'model-pic16' and 'objects-pic16' to compile the
8120 * added target 'port-specific-objects-pic16' to handle the
8121 generated libraries and copy them into the build/ directory
8122 * added target 'clean-intermediate-pic16' to clean intermediate
8123 files into pic16 directory
8124 * in target 'installdirs' added line to create directory pic16 in

8369 * src/SDCCast.c (decorateType),
8370 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
8371 LEFT_OP (left shift)
8373 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8375 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8376 (default behaviour).
8378 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8380 A python script to validate compiler diagnostic messages. It can be
8381 used to verify that sdcc complains about bad c source code and
8382 gives a good location of the error.
8383 * support/valdiag/Makefile,
8384 * support/valdiag/valdiag.py,
8385 * support/valdiag/tests/*
8387 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8400 * src/common.h: added ifndef/define/endif macros
8401 around the header file.
8402 Bug reported from Jesus Calvino-Fraga
8404 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8406 * sdcc.spec: updated
8407 * device/include/Makefile.in: don't install CVS directories
8408 * device/lib/Makefile.in: added removal of CVS directories after install
8409 * doc/Makefile: fixed install, added local_icons
8410 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8411 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8412 * src/ds390/gen.c (genRightShift): fixed bug #870788
8413 * src/SDCCast.c (decorateType): fixed bug #870781
8415 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8417 PIC16 port related changes:
8418 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8419 added variable stackPos,
8421 * gen.c: genCall, assignResultValue: added support for
8422 pushing/retrieving function parameters to/from stack,
8423 genFunction,genEndFunction: setup stack frame for the
8425 genAddrOf: will be changed according to bug 863624
8427 * added files genutils.c and genutils.h which contain gen*
8428 debugged and optimised functions extracted from gen.c
8430 * glue.c: added variable 'externs' which holds extern symbols,
8431 pic16emitRegularMap: is modified to properly handle relocatable
8432 symbols under the new scheme,
8433 pic16createInterruptVect: is modified
8434 pic16printPublics: is modified to emit 'global' assembler directives,
8435 added pic16_printExterns to print extern symbols,
8436 pic16glue: initializes stack/frame pointer in the beginning of
8437 the assembly output. Temporary hack, will be corrected later,
8438 because gplink yet does not support stack and SDCC does not
8439 yet support a type of crt0.o object to create the final binary.
8441 * Removed many lines that contain 8051 legacy code.
8442 * The code is finally placed under a 'code' directive.
8443 * Added port specific options.
8445 * _process_pragma: simplified since now we do not need *special*
8446 include file to define SFR registers. But a separate header
8447 will be needed. This will be developed later.
8448 * _pic16_parseOptions: added, parses port specific options:
8449 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8450 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8451 --preplace-udata-with=
8453 * _pic16_setDefaultOptions: modified to initialize section names,
8454 but hack is temporarly out of order since it needs improvement.
8455 * _pic16_genAssemblerPreamble: configuration words are emitted by
8456 their address instead of their name. This part is incomplete and
8457 supports only the 18Fxx2 devices. Other devices will emit an error
8458 during assembly since they do not contain the same set of config
8460 * _pic16_genIVT: is modified,
8462 * pcode.c: added definitions for some hardware registers that are needed
8464 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8465 All PCI entries are updated. Now LFSR is supported.
8466 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8467 * added pic16_newpCodeOpLit2 to support instructions with
8468 two literal arguments
8469 * pic16_pCode2str: corrected code that emits assembler instructions
8470 with two literal operands and those that have an access bit modifier
8471 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8472 this fixes a bug which caused some labels to be lost, when an
8473 assembler directive was added, i.e. banksel,
8474 * pic16_FixRegisterBanking: improved logic that causes the insertion
8476 * InlineFunction: functions that are called once, are not any more
8477 inlined. This can be a port option in the future,
8479 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8481 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8482 hold the corresponding uninitialized symbols,
8483 * pic16_allocProcessorRegister: registers have explicit marked the
8485 * pic16_allocInternalRegister: registers are explicit marked as
8487 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8488 processing list, so bit registers were lost,
8491 * ralloc.h: added field 'accessBank' and original symbol operand
8492 in register definition,
8493 * removed the field isMapped from register definition,
8495 ** Several functions have been removed from various sources:
8496 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8497 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8498 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8499 pic16_assignRelocatableRegisters
8501 ** others have been introduced:
8502 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8503 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8505 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8507 * support/scripts/inc2h.pl: changed definition of BIT_AT
8508 to emit 'sbit at' instead of 'bit at'. This was a request.
8510 PIC16 port related preliminary changes:
8511 * gen.c: prefixed function popRegFromString with
8512 pic16_ and all references to it corrected
8513 * pcode.c: all pic16_pc_* hardware registers prefixed
8514 with underscore (_),
8515 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8516 * ralloc.c: newReg(): when register is REG_SFR then
8517 set address to rIdx,
8518 pic16_allocProcessorRegister(): marks register wasUsed=0
8519 pic16_writeUsedRegs(): added a call to assign processor
8520 registers via pic16_assignFixedRegisters
8522 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8524 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8525 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8526 variables in unused register banks. Also the SSEG is placed
8527 wherever there is enough space for it, and IDATA can be anywhere
8528 in internal RAM. For now compile using -Wl-Y[stack_size].
8529 The mem file is different for this option as well, since it
8530 makes no sense of talking about DSEG lenght.
8532 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8534 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8535 in certain cases, e.g. when ROM assignment, patch provided
8536 from Albert den Haan.
8538 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8777 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8779 * src/SDCCast.c (decorateType): disabled a transformation I added in
8780 revision 1.188 (access to fields of a structure at an absolute address);
8781 it breaks with bitfields, extern declarations, and gcse analysis.
8782 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8783 could be assigned through a pointer, so don't complain.
8784 * src/SDCCast.c (astErrors),
8786 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
8788 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

9540 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9541 fetching of the pointer
9542 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9543 copied from genNearPointerSet()
9544 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9545 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9546 If they pop r0/r1 they must be called in the opposite order than aopOp().
9547 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9548 (resp. --stack-auto), prepared for --xstack

9559 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9561 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9562 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9563 type for bits was changed. It resulted in bit variables becoming
9564 global, which is not permitted in PIC 14 assembly output.
9566 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9568 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9581 A few small changes that speed up the peephole optimizer.
9585 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9587 Try to make the peephole optimizer smarter by maintaining
9588 an association between the assembly source code and the
9589 iCodes that originated them. Put this information to use
9590 with a new peephole rule condition "notVolatile" so that
9591 the rules can be aggressive yet still safe.
9596 * src/mcs51/peeph.def
9598 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9602 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9603 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9604 if the left or right operand symbols have the accuse flag set.
9606 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9608 Changed the type of the result of the ! (NOT) operator to char;
9609 previously it returned the same type as the source. This allows
9610 us to eliminate all the genFloatNot functions (all of its target
9611 implementations were very buggy) since !float can use the same
9614 * src/SDCCicode.c (ast2iCode): ! returns char

9616 * src/ds390/gen.c (genNot, genNotFloat),
9617 * src/z80/gen.c (genNot, genNotFloat),
9618 * src/pic/gen.c (genNot, genNotFloat),

9623 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9624 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9625 during interrupts. Ensure WSAVE is located at a shared bank address.
9626 2. Fixed page selection in some places
9627 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9628 the registers name strings.
9629 4. Fixed "signed / unsigned compare" compiler warnings.
9630 5. The PIC port manages its own allocation of the general purpose
9631 registers, but makes no attempt to reuse them. As a result when
9632 compiling it soon runs out of general purpose registers. Some
9633 additional code was added to the files pcode.c and device.c to walk
9634 through the function call tree and rename the registers so that they
9644 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9645 genPlus() & genMinus() when the result is the same as left or right
9647 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9651 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9653 Made bitfield a distinct type from bit so that bitfields
9654 convert as per ANSI C and bits retain their traditional
9655 boolean style behaviour. Implemented bitfield support in
9663 * src/ds390/gen.c: bit v bitfield split
9664 * src/z80/gen.c: New support for bitfields
9665 * support/regression/tests/bitfields.c: reenabled z80,
9668 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9670 Rules 246.x, 247.x relate to bitfields, the others speed up
9671 access to xdata mapped I/O devices.
9673 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9675 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9677 Cleaned up genPackBits and genUnpackBits and added two helper
9678 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9679 for literal assignments in genPackBits (thanks to Frieder for
9685 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9687 Fixed bug #748310 (pointer to function type mishandled when the
9688 function name is omitted). Also fixed a SIGSEGV when a function
9689 attribute (reentrant, etc) is used on a non-function or on a
9690 function but misplaced before the parameter list.
9692 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9694 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9695 * support/Util/SDCCerr.h,
9696 * support/Util/SDCCerr.c: Added func attr misuse error msg

9717 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9719 Made the constant following the "interrupt" keyword optional. If
9720 omitted, the function will not automatically be given an entry
9721 in the interrupt vector table (similar to #pragma NOIV, but
9722 less syntacticly kludgy). The interrupt number is also now
9723 range checked. Also fixed a bug in the high order bit example

9739 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9741 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9742 be re-activated by defining REDUCE_LITERALS)
9743 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9744 unsigned, but are signed by default
9745 * src/SDCCval.c (constVal): rearranged
9746 * src/SDCCval.c (valMod): preliminary fix
9747 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10254 messages from optionsTable when a port is not configured, added
10255 support for the PIc16 port in the ports table, when executing
10256 the compiler with no port specified on command line, a default
10257 port is selected with the new macro DEFAULT_PORT which is
10258 defined in port.h, in setDefaultOptions() linkOptions is removed
10259 from initialization assignment, since now it is a set,
10260 parseCmdLine uses setParseWithComma for linkOptions, in
10261 linkEdit() linkOptions are accessed with new function indexSet()
10262 which returns the i'th item of a set variable. See SDCCset.c, in
10263 linkEdit() when calling buildCmdLine(), added linkOptions as
10264 last argument. Now users can pass arguments to gplink via the
10265 -Wl option, main() uses pic16glue() to glue up pic16 programs

10279 gpasm complaining and test the linkage with gplink, _linkCmd and
10280 _asmCmd changed to be more gplink and gpasm friendly
10281 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10282 produced an error when parsed, peep rule 12 is added to utilize
10283 movff, but it is commented out since the pCode does not support
10284 yet a command with 2 address arguments

11346 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11347 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11349 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11351 * in /sdcc/as/mcs51/ changed these files in order to create an
11352 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11353 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11354 following files to include the previous two files: aslink.dsp,
11355 Makefile.aslink, Makefile.bcc, and Makefile.in.
11357 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11358 .adb instead of .cdb
11360 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11362 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11363 value from option --iram-size.
11365 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11367 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11370 2002-09-18 <wiml AT hhhh.org>
11372 * SDCClrange.h: exposed setFromRange() and setToRange()
11373 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11374 packRegsForAccUse() (bug 542397)
11375 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11376 multiple times and emitting the fetch operations more than once
11377 added aopGetUsesAcc() function to allow binary operators to
11378 fetch their operands in the correct order; made genMinus() emit
11379 compact code for X = LITERAL - Y
11381 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11382 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11383 sprintf() in line 1267.
11385 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11386 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11389 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11390 Changes to aslink (All the changes are marked with 'JCF'):
11392 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11395 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11396 area BSEG. Also moves, if possible, the DATA area down into the internal
11397 ram so more space is available.
11399 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11402 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11403 not bytes. Function summary() which creates a memory usage summary
11404 file with extension .mem. Reports of overlaping stack and small stack
11405 size. If the space for the stack is less than 16 bytes aslink trows a
11408 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11409 the 8051. Option 'y' for memory summary output file.
11411 Changes to sdcc (All the changes are marked with 'JCF'):
11413 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11415 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11416 overlaying area for it (uses RegBankUsed[4]).
11418 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11419 bank zero as used by default. By default aslink locates the stack
11420 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11421 the creation of the .mem file. Delegates the allocation of data area
11422 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11423 the begining of the stack area to aslink.
11425 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11426 glue() in SDCCglue.c creates an area for it.
11428 2002-09-03 Borut Razem <borut.razem AT siol.net>
11429 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11430 sdcc/src/pic/glue.c:
11431 introduced atexit() handler for teporay files removal in case of
11432 errors, assertions, ...
11434 2002-08-29 Borut Razem <borut.razem AT siol.net>
11435 * sdcc/support/cpp2/auto-host_vc_in.h:
11436 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11437 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11438 Maybe there is a similar problem with BORLANDC? It should be checked!
11440 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11441 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11442 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11443 was not executed, and the compiler (cl) launched a warning:
11444 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11446 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11447 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11449 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11450 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11452 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11453 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11454 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11455 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11456 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11457 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11458 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11459 - added Release configuration in VS projects
11460 - review of compiler an linker options
11461 - VC .exe files are generated in bin_vc directory, not to interfere
11462 with binaries generated from other projects (cygwin, mingw, bcc ...)
11464 * sdcc/src/yacc.dsp: added
11466 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11467 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11468 and insert the version number definitions from .version
11470 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11472 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11473 added - genarate auto-host.h using auto-host_vc_in.h as template
11476 removed from CVS, generated automatically
11478 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11479 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11481 2002-08-11 Borut Razem <borut.razem AT siol.net>
11482 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11484 2002-08-10 Borut Razem <borut.razem AT siol.net>
11485 * src/SDCCmain.c (main):
11486 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11487 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11488 The consequence was that some temporary files were not removed.
11491 unification of code in functions tempfilename() and tempfile():
11492 function tempnam() is defined in Visual Studio 6.0 and .NET
11494 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11496 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11497 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11498 - removed compiler command line option /WX: Treats all warnings as errors
11499 - update a list of source files, included into the project
11501 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11502 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11503 changed project type to Generic Project so that can be correcly converted to VS.NET project
11505 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11507 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11509 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11511 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11512 added return 0 statements after assert() to make compiler happy
11514 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11515 added newline in the def file to keep MSC compiler satisfied
11517 * sdcc/src/z80/gen.c:
11518 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11519 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11520 - solved MSC error in function aopDump()
11522 * sdcc_vc.h: define PREFIX as "\\sdcc"
11524 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11525 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11528 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11529 - Rewrote the register banking algorithm.
11530 - Added pCode live-range analysis to registers (for now, only non-used and
11531 singly-used registers optimized away)
11533 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11535 * 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.

11564 2002-03-28 Johan Knol <johan AT balder>
11566 * src/SDCCval.c: fixed bug #532436
11568 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11570 Added "char *Processor" field to the port structure.
11573 Added -p option. Allows port dependent processor to be specified.
11576 Initialized the new field char *Processor field to NULL in all ports
11579 Compiler generated registers for interrupt context saving
11580 were not getting allocated.
11582 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11585 Fixed left shift. Will promote the left side of a left shift
11586 if a) left shifting more than size of operand or b) when assigned
11587 to something size > size of left side
11589 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11591 tons of changes. Register allocation has been
11592 rewritten. Added customization for the various PICs. Flow
11593 analysis is restructured. ...
11595 * src/pic/device.h:
11598 * src/pic/device.c:
11599 Added. device.c is a PIC port hack to accomodate variations
11602 2002-03-13 Michael Hope <michaelh AT vroom>
11604 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11606 2002-03-04 johanknol <johanknol AT manik>
11608 * /src/SDCCval.c: fixed
11610 const unsigned char arr[][2] = { { 0, 1 } };
11611 t18.c:1: error: Initializer element is not constant
