1501 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1502 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1504 One basic decision: e.g. src/clean.mk includes further files. In order
1505 to make this work there are two solutions:
1506 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1507 run configure on them. This way they can use
1508 'include $(srcdir)/port-clean.mk'
1509 - always include clean.mk by the Makefile at the same level. To avoid
1510 that `make clean` tries to include and build Makefile.dep the
1511 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1512 implemented, because now even `make uninstall` doesn't create
1513 Makefile.in. clean.mk could be eliminated by pasting it in
1516 * debugger/mcs51/Makefile.in: build own objects from library sources
1517 (SLIB, SDCC) in current directory
1519 * configure, configure.in: renamed --disable-device-lib-build in
1520 --disable-device-lib; added --enable-doc, the required tools are
1521 searched by configure; added result message; the toolchain for the
1522 belonging ports are now only built, if the port is enabled.
1524 * support/regression/*: all output is written in directory gen, because
1525 the fwk and ports directories don't livet in the build tree using vpath
1527 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1528 --disable-device-lib, added --enable-doc, added section VPATH
1530 * sim/ucsim/configure.in,
1531 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1532 z80 are enabled by default
1534 2006-04-24 Raphael Neider <rneider AT web.de>
1536 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1537 to config word, "pic14_"-prefixed some extern functions
1538 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1539 config word has been found
1540 * src/pic/device.h: added prototypes
1541 * src/pic/pcode.c: added "pic14_"-prefix where needed
1542 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1544 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1559 (pCodeRegOptimizeRegUsage): fixed typo in comment

1791 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1793 * src/SDCCpeeph.c (operandsLiteral): new, added,

1804 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
1805 implemented patch 1120823 Thanks to Willy De la Court (normal
1806 interrupts need an interrupt number now if they are made critical),
1807 and enabled nesting of critical functions though not for gbz80
1808 (genCritical, genEndCritical): added functions
1809 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1810 * src/z80/mappings.i: added "ei" to all mappings
1812 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1814 * sim/ucsim/cmd.src/newcmdcl.h: applied patch fixing GCC 4.1 build
1815 submitted by the Debian SDCC maintainer Aurelien Jarno:
1816 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1817 archive with gcc 4.1 on mips and wrote the patch"
1819 2006-03-16 Raphael Neider <rneider AT web.de>
1821 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1822 the left operand is shorter than the result (c* = lit-c* + int),
1824 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1827 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1829 * src/.version: increased version number to 2.5.5
1830 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1831 linking is done manually in pic16 port's _linkEdit,
1832 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1833 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1834 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1835 allocate asmop as AOP_ACC,
1836 (aopForRemat): added parameter 'bool result' in function declaration,
1837 (pic16_aopGet): return AOP_ACC when accessing WREG,
1838 (pic16_popGetTempReg): minor modification,
1839 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1840 'pic16_allocWithIdx',
1841 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1842 calling function in absolute addresses,
1843 (genAssign): take into account AOP_ACC asmop,
1844 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1845 * src/pic16/pcoderegs.c: some debug functions and lines added,
1846 * src/pic16/ralloc.c (decodeRegType): added but commented out,
1847 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1849 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1850 call to allocReg, not by manually allocating a new one,
1851 (pic16_assignRegisters): now before going through the register
1852 allocating functions mark all registers as free. This eliminates some
1853 side effects resulting from peephole parser done earlier in the backbone
1855 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1857 * src/SDCCicode.c (geniCodeLogic),

1876 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1877 (aopForSym, aopOp): increment asmop.allocated if reused,
1878 (freeAsmop): decrement asmop.allocated and check for zero instead of
1880 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1881 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1882 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1905 2006-03-06 Borut Razem <borut.razem AT siol.net>
1907 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1908 made the linker quiet
1910 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1912 * src/pic16/gen.c (genPcall): fixed bug #1443644
1913 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1914 which dumps before the function entry point a data byte which represents
1915 the number of the local variables used by the specified function, added
1916 'xinst' for initial support for Extended Instruction Support,
1917 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1918 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1919 port->fun_prefix anymore (may change later),
1920 (genFunction, genEndFunction): do not store/restore local registers for
1921 _main (this should take care the --main-return command line option in
1923 (genOr): removed some legacy pic-port instructions,
1924 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1925 performing operations with SFR's causes data to be written more than
1926 once to each SFR. Perhaps SFRs should be handled in special cases...
1927 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1929 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1930 into account for stack starting position,
1931 (struct OPTIONS pic16_optionsTable): added command line argument
1932 --extended or -y for Extended Instruction Support,
1933 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1934 (deassignLRs): *** perhaps the most important change, old 'for' code
1935 (commented out for reference), didn't account for some registers which
1936 were left marked 'not free' after a pointer operation. The change
1937 reduces register usage a lot in some cases

4323 but as registers instead (AOP_REG) using the fReturnIdx array,
4324 * (pic16_freeAsmop): remove the freed register from the
4325 _G.sregsAlloc field,
4326 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4327 a compare of 'WREG',
4328 * (pic16_popGetTempRegCond): changed function prototype, now
4329 function takes also a bitVector argument v which holds the current
4330 set of registers that are allocated for stack access by aopForSym,
4331 registers allocated in aopForSym for accessing stack symbols are not
4332 any more part of the functions usedRegs field,
4333 * (genCall): some times aopOp is called for a stack variable to be
4334 send, aopForSym might perform the push, if this is true make sure
4335 that genCall doesn't push the variable twice by testing _G.resDirect,
4336 * (genFunction): changed testing for unspecified interrupt number
4337 from 256 to INTNO_UNSPEC,
4338 * modified selection scheme of frame pointer generation. Previously
4339 if function did use local registers a frame pointer was generated,
4340 now a frame pointer is generated only if function has arguments
4341 (that need PLUSW2 register access), or has stack arguments, or the
4342 compiler is not instructed to omit the frame pointer,
4343 * (genEndFunction): before restoring local registers that were saved
4344 in the function preamble, also restore the registers that *might*
4345 have been allocated for stack access,
4346 * (genRet): removed some old comments,
4347 * (genCmp, the active (RN's) version): added a call to the
4348 pic16_genCmp_special function to perform the compare with a more
4349 robust and optimized way,
4350 * (genInline): a feature has been added in inline code generation,
4351 which allows a wildcard variable substitution when writing inline
4352 assembly. Code is incomplete and experimental therefore undocumented,
4353 * (genCast): changed order of aopOp for result and right to allow
4354 aopForSym to directly load the result if possible,
4355 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4356 perform an optimized compare on some selected special occasions,
4357 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4358 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4359 generate an IVT any more,
4360 * src/pic16/main.c (pic16_optionsTable): added command line option
4362 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4363 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4365 * src/pic16/NOTES: Raphael Neider added in list of active developers
4366 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4367 jumptable_end to prevent bug #,
4368 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4369 inCond and outCond fields,
4370 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4371 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4372 turn off register spilling,
4373 * (packRegsForOneUse): synced with other ports' versions although it
4374 is not used currently,
4375 * (pic16_packRegisters): added an optimization while reading
4376 structure bitfields, some registers may be saved (malloc code is
4377 decreased by 80 bytes)
4379 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4381 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4382 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4383 this can be optimized more?
4385 2005-03-10 Raphael Neider <rneider AT web.de>
4387 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4388 genNearPointerGet): (hopefully) fixed access to bitfields via
4389 pointers (p->bitN = x; and x = p->bitN; failed)
4391 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4715 access stack and frame pointers. They are initially assigned to
4716 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
4717 accessing SFRs. Updated all occurences of modification of stack or
4718 frame pointer in gen.c and pcode.c,
4719 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
4720 assigning of a literal value to pointers,

5024 generated for switch statements. For now you need to set the
5025 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5026 Now 4 algorithms for mcs51 jumptable generation are used:
5027 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5028 addresses loaded pc-relative for up to 112 cases and stack-pushing
5029 target addresses loaded with offset from dptr for up to 256 cases.

5061 * added libc directory. The current version of LibC contains string
5062 functions, ctype functions and macros and some functions of the
5063 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5064 be extensively tested in the future. Standard disclaimer here.

5078 * (genCmp): experimental code for new genCmp which uses PIC18's
5079 special compare&skip instructions. Initial tests fail some times
5080 with variables grater than 1 byte in size, so new code is disabled,
5081 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5083 * (genCast): began a fix to optimize the casting of a bit to another
5084 bit, now assigning a bitfield to another bitfield will fail, sorry,

5098 registers when it shouldn't,
5099 * src/pic16/ralloc.c (allocReg): add preliminary support for
5100 supporting a limited set of temporary registers,
5102 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8109 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8110 loaded with the linker search paths (-L arguments) and the libraries
8111 to be linked with the current source (-l arguments). Changes
8112 currently will affect only the pic16 port.
8113 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8114 include path the port specific paths and port specific libraries,
8115 * gplink command now contains the $3 argument,
8116 * src/pic16/device.h,
8117 * src/pic16/device.c,: structure PIC_device is made public and

8133 Documenting changes from previous commits.
8134 * configure.in (version 1.56),
8135 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8136 when generating output files to configure the pic16 library,
8137 but now I've commented it out, since gputils aren't installed in the
8138 SF compile farm, so library won't compile
8140 * device/lib/Makefile.in (version 1.56): initially I've added in
8141 target 'all' the prerequestive 'model-pic16' so it compiled the
8142 pic16 library, but now I've commented it out for the same reasons
8144 * added targets 'model-pic16' and 'objects-pic16' to compile the
8146 * added target 'port-specific-objects-pic16' to handle the
8147 generated libraries and copy them into the build/ directory
8148 * added target 'clean-intermediate-pic16' to clean intermediate
8149 files into pic16 directory
8150 * in target 'installdirs' added line to create directory pic16 in

8172 option so that it actually works. Made it specific to the z80, since
8173 the gbz80 doesn't have these kinds of I/O ports.
8175 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8177 * device/include/z180.h,

8204 data are now emitted in sorted order to reduce section naming,
8205 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8206 weren't marked as being in the access bank,

8399 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8401 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8402 (default behaviour).
8404 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8406 A python script to validate compiler diagnostic messages. It can be
8407 used to verify that sdcc complains about bad c source code and
8408 gives a good location of the error.
8409 * support/valdiag/Makefile,
8410 * support/valdiag/valdiag.py,
8411 * support/valdiag/tests/*

8428 Bug reported from Jesus Calvino-Fraga
8430 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8432 * sdcc.spec: updated
8433 * device/include/Makefile.in: don't install CVS directories
8434 * device/lib/Makefile.in: added removal of CVS directories after install
8435 * doc/Makefile: fixed install, added local_icons
8436 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8437 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8438 * src/ds390/gen.c (genRightShift): fixed bug #870788

8441 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8443 PIC16 port related changes:
8444 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8445 added variable stackPos,
8447 * gen.c: genCall, assignResultValue: added support for
8448 pushing/retrieving function parameters to/from stack,
8449 genFunction,genEndFunction: setup stack frame for the
8451 genAddrOf: will be changed according to bug 863624
8453 * added files genutils.c and genutils.h which contain gen*
8454 debugged and optimised functions extracted from gen.c
8456 * glue.c: added variable 'externs' which holds extern symbols,
8457 pic16emitRegularMap: is modified to properly handle relocatable
8458 symbols under the new scheme,
8459 pic16createInterruptVect: is modified
8460 pic16printPublics: is modified to emit 'global' assembler directives,
8461 added pic16_printExterns to print extern symbols,
8462 pic16glue: initializes stack/frame pointer in the beginning of
8463 the assembly output. Temporary hack, will be corrected later,
8464 because gplink yet does not support stack and SDCC does not
8465 yet support a type of crt0.o object to create the final binary.
8467 * Removed many lines that contain 8051 legacy code.
8468 * The code is finally placed under a 'code' directive.
8469 * Added port specific options.
8471 * _process_pragma: simplified since now we do not need *special*
8472 include file to define SFR registers. But a separate header
8473 will be needed. This will be developed later.
8474 * _pic16_parseOptions: added, parses port specific options:
8475 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8476 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8477 --preplace-udata-with=
8479 * _pic16_setDefaultOptions: modified to initialize section names,
8480 but hack is temporarly out of order since it needs improvement.
8481 * _pic16_genAssemblerPreamble: configuration words are emitted by
8482 their address instead of their name. This part is incomplete and
8483 supports only the 18Fxx2 devices. Other devices will emit an error
8484 during assembly since they do not contain the same set of config
8486 * _pic16_genIVT: is modified,
8488 * pcode.c: added definitions for some hardware registers that are needed
8490 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8491 All PCI entries are updated. Now LFSR is supported.
8492 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8493 * added pic16_newpCodeOpLit2 to support instructions with
8494 two literal arguments
8495 * pic16_pCode2str: corrected code that emits assembler instructions
8496 with two literal operands and those that have an access bit modifier
8497 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8498 this fixes a bug which caused some labels to be lost, when an
8499 assembler directive was added, i.e. banksel,
8500 * pic16_FixRegisterBanking: improved logic that causes the insertion
8502 * InlineFunction: functions that are called once, are not any more
8503 inlined. This can be a port option in the future,
8505 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8507 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8508 hold the corresponding uninitialized symbols,
8509 * pic16_allocProcessorRegister: registers have explicit marked the
8511 * pic16_allocInternalRegister: registers are explicit marked as
8513 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8514 processing list, so bit registers were lost,
8517 * ralloc.h: added field 'accessBank' and original symbol operand
8518 in register definition,
8519 * removed the field isMapped from register definition,
8521 ** Several functions have been removed from various sources:
8522 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8523 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8524 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8525 pic16_assignRelocatableRegisters
8527 ** others have been introduced:
8528 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8529 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8531 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8533 * support/scripts/inc2h.pl: changed definition of BIT_AT
8534 to emit 'sbit at' instead of 'bit at'. This was a request.
8536 PIC16 port related preliminary changes:
8537 * gen.c: prefixed function popRegFromString with
8538 pic16_ and all references to it corrected
8539 * pcode.c: all pic16_pc_* hardware registers prefixed
8540 with underscore (_),
8541 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8542 * ralloc.c: newReg(): when register is REG_SFR then
8543 set address to rIdx,
8544 pic16_allocProcessorRegister(): marks register wasUsed=0
8545 pic16_writeUsedRegs(): added a call to assign processor
8546 registers via pic16_assignFixedRegisters
8548 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8550 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8551 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8552 variables in unused register banks. Also the SSEG is placed
8553 wherever there is enough space for it, and IDATA can be anywhere
8554 in internal RAM. For now compile using -Wl-Y[stack_size].
8555 The mem file is different for this option as well, since it
8556 makes no sense of talking about DSEG lenght.
8558 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8560 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8561 in certain cases, e.g. when ROM assignment, patch provided
8562 from Albert den Haan.

9566 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9567 fetching of the pointer
9568 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9569 copied from genNearPointerSet()
9570 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9571 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9572 If they pop r0/r1 they must be called in the opposite order than aopOp().
9573 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9574 (resp. --stack-auto), prepared for --xstack

9585 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9587 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9588 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9589 type for bits was changed. It resulted in bit variables becoming
9590 global, which is not permitted in PIC 14 assembly output.
9592 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9594 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9607 A few small changes that speed up the peephole optimizer.
9611 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9613 Try to make the peephole optimizer smarter by maintaining
9614 an association between the assembly source code and the
9615 iCodes that originated them. Put this information to use
9616 with a new peephole rule condition "notVolatile" so that
9617 the rules can be aggressive yet still safe.
9622 * src/mcs51/peeph.def
9624 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9628 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9629 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9630 if the left or right operand symbols have the accuse flag set.
9632 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9634 Changed the type of the result of the ! (NOT) operator to char;
9635 previously it returned the same type as the source. This allows
9636 us to eliminate all the genFloatNot functions (all of its target
9637 implementations were very buggy) since !float can use the same
9640 * src/SDCCicode.c (ast2iCode): ! returns char
9641 * src/mcs51/gen.c (genNot, genNotFloat),
9642 * src/ds390/gen.c (genNot, genNotFloat),
9643 * src/z80/gen.c (genNot, genNotFloat),
9644 * src/pic/gen.c (genNot, genNotFloat),
9645 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9647 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9649 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9650 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9651 during interrupts. Ensure WSAVE is located at a shared bank address.
9652 2. Fixed page selection in some places
9653 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9654 the registers name strings.
9655 4. Fixed "signed / unsigned compare" compiler warnings.
9656 5. The PIC port manages its own allocation of the general purpose
9657 registers, but makes no attempt to reuse them. As a result when
9658 compiling it soon runs out of general purpose registers. Some
9659 additional code was added to the files pcode.c and device.c to walk
9660 through the function call tree and rename the registers so that they
9670 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9671 genPlus() & genMinus() when the result is the same as left or right

9677 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9679 Made bitfield a distinct type from bit so that bitfields
9680 convert as per ANSI C and bits retain their traditional
9681 boolean style behaviour. Implemented bitfield support in
9689 * src/ds390/gen.c: bit v bitfield split
9690 * src/z80/gen.c: New support for bitfields
9691 * support/regression/tests/bitfields.c: reenabled z80,
9694 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9696 Rules 246.x, 247.x relate to bitfields, the others speed up
9697 access to xdata mapped I/O devices.
9699 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9701 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9703 Cleaned up genPackBits and genUnpackBits and added two helper
9704 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9705 for literal assignments in genPackBits (thanks to Frieder for
9711 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9713 Fixed bug #748310 (pointer to function type mishandled when the
9714 function name is omitted). Also fixed a SIGSEGV when a function
9715 attribute (reentrant, etc) is used on a non-function or on a
9716 function but misplaced before the parameter list.
9718 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9720 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9721 * support/Util/SDCCerr.h,
9722 * support/Util/SDCCerr.c: Added func attr misuse error msg
9724 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9726 Fixed bug #787649 by anonymous
9727 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr

9743 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9745 Made the constant following the "interrupt" keyword optional. If
9746 omitted, the function will not automatically be given an entry
9747 in the interrupt vector table (similar to #pragma NOIV, but
9748 less syntacticly kludgy). The interrupt number is also now
9749 range checked. Also fixed a bug in the high order bit example

9763 * src/SDCCicode.c (operandOperation): rewritten some ops
9764 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9765 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9767 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9768 be re-activated by defining REDUCE_LITERALS)
9769 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9770 unsigned, but are signed by default
9771 * src/SDCCval.c (constVal): rearranged
9772 * src/SDCCval.c (valMod): preliminary fix
9773 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9815 constants are unsigned; added recognition of "u" flag for unsigned
9816 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9817 * src/SDCCval.c (valDiv, valMod): fixed signdness

10226 the regression tests I'm not brave enough to enable 245.b, 245.c
10227 * doc/sdccman.lyx: added latex preamble for hyperref package.
10228 Using pdflatex this will give you a hyperlinked pdf file with

10279 added if/endif conditional macros to remove options help
10280 messages from optionsTable when a port is not configured, added
10281 support for the PIc16 port in the ports table, when executing
10282 the compiler with no port specified on command line, a default
10283 port is selected with the new macro DEFAULT_PORT which is
10284 defined in port.h, in setDefaultOptions() linkOptions is removed
10285 from initialization assignment, since now it is a set,
10286 parseCmdLine uses setParseWithComma for linkOptions, in
10287 linkEdit() linkOptions are accessed with new function indexSet()
10288 which returns the i'th item of a set variable. See SDCCset.c, in
10289 linkEdit() when calling buildCmdLine(), added linkOptions as
10290 last argument. Now users can pass arguments to gplink via the
10291 -Wl option, main() uses pic16glue() to glue up pic16 programs

10305 gpasm complaining and test the linkage with gplink, _linkCmd and
10306 _asmCmd changed to be more gplink and gpasm friendly
10307 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10308 produced an error when parsed, peep rule 12 is added to utilize
10309 movff, but it is commented out since the pCode does not support
10310 yet a command with 2 address arguments
10312 2003-05-18 <johan AT balder>
10314 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10341 2003-05-11 Borut Razem <borut.razem AT siol.net>
10343 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine

11362 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11363 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11366 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11367 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11369 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11370 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11372 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11373 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11375 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11377 * in /sdcc/as/mcs51/ changed these files in order to create an
11378 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11379 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11380 following files to include the previous two files: aslink.dsp,
11381 Makefile.aslink, Makefile.bcc, and Makefile.in.
11383 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11384 .adb instead of .cdb
11386 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11388 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11389 value from option --iram-size.
11391 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11393 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11396 2002-09-18 <wiml AT hhhh.org>
11398 * SDCClrange.h: exposed setFromRange() and setToRange()
11399 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11400 packRegsForAccUse() (bug 542397)
11401 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11402 multiple times and emitting the fetch operations more than once
11403 added aopGetUsesAcc() function to allow binary operators to
11404 fetch their operands in the correct order; made genMinus() emit
11405 compact code for X = LITERAL - Y
11407 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11408 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11409 sprintf() in line 1267.
11411 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11412 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11415 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11416 Changes to aslink (All the changes are marked with 'JCF'):
11418 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11421 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11422 area BSEG. Also moves, if possible, the DATA area down into the internal
11423 ram so more space is available.
11425 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11428 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11429 not bytes. Function summary() which creates a memory usage summary
11430 file with extension .mem. Reports of overlaping stack and small stack
11431 size. If the space for the stack is less than 16 bytes aslink trows a
11434 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11435 the 8051. Option 'y' for memory summary output file.
11437 Changes to sdcc (All the changes are marked with 'JCF'):
11439 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11441 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11442 overlaying area for it (uses RegBankUsed[4]).
11444 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11445 bank zero as used by default. By default aslink locates the stack
11446 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11447 the creation of the .mem file. Delegates the allocation of data area
11448 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11449 the begining of the stack area to aslink.
11451 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11452 glue() in SDCCglue.c creates an area for it.
11454 2002-09-03 Borut Razem <borut.razem AT siol.net>
11455 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11456 sdcc/src/pic/glue.c:
11457 introduced atexit() handler for teporay files removal in case of
11458 errors, assertions, ...
11460 2002-08-29 Borut Razem <borut.razem AT siol.net>
11461 * sdcc/support/cpp2/auto-host_vc_in.h:
11462 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11463 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11464 Maybe there is a similar problem with BORLANDC? It should be checked!
11466 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11467 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11468 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11469 was not executed, and the compiler (cl) launched a warning:
11470 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11472 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11473 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11475 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11476 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11478 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11479 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11480 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11481 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11482 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11483 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11484 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11485 - added Release configuration in VS projects
11486 - review of compiler an linker options
11487 - VC .exe files are generated in bin_vc directory, not to interfere
11488 with binaries generated from other projects (cygwin, mingw, bcc ...)
11490 * sdcc/src/yacc.dsp: added
11492 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11493 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11494 and insert the version number definitions from .version
11496 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11498 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11499 added - genarate auto-host.h using auto-host_vc_in.h as template
11502 removed from CVS, generated automatically
11504 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11505 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11507 2002-08-11 Borut Razem <borut.razem AT siol.net>
11508 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11510 2002-08-10 Borut Razem <borut.razem AT siol.net>
11511 * src/SDCCmain.c (main):
11512 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11513 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11514 The consequence was that some temporary files were not removed.
11517 unification of code in functions tempfilename() and tempfile():
11518 function tempnam() is defined in Visual Studio 6.0 and .NET
11520 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11522 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11523 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11524 - removed compiler command line option /WX: Treats all warnings as errors
11525 - update a list of source files, included into the project
11527 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11528 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11529 changed project type to Generic Project so that can be correcly converted to VS.NET project
11531 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11533 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11535 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11537 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11538 added return 0 statements after assert() to make compiler happy
11540 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11541 added newline in the def file to keep MSC compiler satisfied
11543 * sdcc/src/z80/gen.c:
11544 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11545 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11546 - solved MSC error in function aopDump()
11548 * sdcc_vc.h: define PREFIX as "\\sdcc"
11550 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11551 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11553 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11554 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11555 - Rewrote the register banking algorithm.
11556 - Added pCode live-range analysis to registers (for now, only non-used and
11557 singly-used registers optimized away)
11559 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11561 * 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.
11563 2002-05-10 Scott Dattalo <scott AT dattalo.com>

11576 2002-04-15 Michael Hope <michaelh AT vroom>
11578 * device/lib/z80/printf.c (sprintf): Added.
11580 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11582 * src/z80/peeph.def: Added transpose redundent load rule.
11584 * src/z80/main.c: Added force callee saves for jaune.
11586 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11588 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11590 2002-03-28 Johan Knol <johan AT balder>
11592 * src/SDCCval.c: fixed bug #532436
11594 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11596 Added "char *Processor" field to the port structure.
11599 Added -p option. Allows port dependent processor to be specified.
11602 Initialized the new field char *Processor field to NULL in all ports
11605 Compiler generated registers for interrupt context saving
11606 were not getting allocated.
11608 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11611 Fixed left shift. Will promote the left side of a left shift
11612 if a) left shifting more than size of operand or b) when assigned
11613 to something size > size of left side
11615 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11617 tons of changes. Register allocation has been
11618 rewritten. Added customization for the various PICs. Flow
11619 analysis is restructured. ...
11621 * src/pic/device.h:
11624 * src/pic/device.c:
11625 Added. device.c is a PIC port hack to accomodate variations
11628 2002-03-13 Michael Hope <michaelh AT vroom>
