1452 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1454 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1455 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1457 One basic decision: e.g. src/clean.mk includes further files. In order
1458 to make this work there are two solutions:
1459 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1460 run configure on them. This way they can use
1461 'include $(srcdir)/port-clean.mk'
1462 - always include clean.mk by the Makefile at the same level. To avoid
1463 that `make clean` tries to include and build Makefile.dep the
1464 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1465 implemented, because now even `make uninstall` doesn't create
1466 Makefile.in. clean.mk could be eliminated by pasting it in
1469 * debugger/mcs51/Makefile.in: build own objects from library sources
1470 (SLIB, SDCC) in current directory
1472 * configure, configure.in: renamed --disable-device-lib-build in
1473 --disable-device-lib; added --enable-doc, the required tools are
1474 searched by configure; added result message; the toolchain for the
1475 belonging ports are now only built, if the port is enabled.
1477 * support/regression/*: all output is written in directory gen, because
1478 the fwk and ports directories don't livet in the build tree using vpath
1480 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1481 --disable-device-lib, added --enable-doc, added section VPATH
1483 * sim/ucsim/configure.in,
1484 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1485 z80 are enabled by default
1487 2006-04-24 Raphael Neider <rneider AT web.de>
1489 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1490 to config word, "pic14_"-prefixed some extern functions
1491 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1492 config word has been found
1493 * src/pic/device.h: added prototypes
1494 * src/pic/pcode.c: added "pic14_"-prefix where needed
1495 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1497 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1512 (pCodeRegOptimizeRegUsage): fixed typo in comment

1785 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1786 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1787 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1788 allocate asmop as AOP_ACC,
1789 (aopForRemat): added parameter 'bool result' in function declaration,
1790 (pic16_aopGet): return AOP_ACC when accessing WREG,
1791 (pic16_popGetTempReg): minor modification,
1792 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1793 'pic16_allocWithIdx',
1794 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1795 calling function in absolute addresses,
1796 (genAssign): take into account AOP_ACC asmop,
1797 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1798 * src/pic16/pcoderegs.c: some debug functions and lines added,
1799 * src/pic16/ralloc.c (decodeRegType): added but commented out,
1800 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1802 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1803 call to allocReg, not by manually allocating a new one,
1804 (pic16_assignRegisters): now before going through the register
1805 allocating functions mark all registers as free. This eliminates some
1806 side effects resulting from peephole parser done earlier in the backbone
1808 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1830 (aopForSym, aopOp): increment asmop.allocated if reused,
1831 (freeAsmop): decrement asmop.allocated and check for zero instead of
1833 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1834 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

1856 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1858 2006-03-06 Borut Razem <borut.razem AT siol.net>
1860 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1861 made the linker quiet
1863 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1865 * src/pic16/gen.c (genPcall): fixed bug #1443644
1866 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1867 which dumps before the function entry point a data byte which represents
1868 the number of the local variables used by the specified function, added
1869 'xinst' for initial support for Extended Instruction Support,
1870 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1871 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1872 port->fun_prefix anymore (may change later),
1873 (genFunction, genEndFunction): do not store/restore local registers for
1874 _main (this should take care the --main-return command line option in
1876 (genOr): removed some legacy pic-port instructions,
1877 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1878 performing operations with SFR's causes data to be written more than
1879 once to each SFR. Perhaps SFRs should be handled in special cases...
1880 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1882 * src/pic16/main.c (_process_pragma): stack bound checking did not take

1885 --extended or -y for Extended Instruction Support,
1886 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1887 (deassignLRs): *** perhaps the most important change, old 'for' code
1888 (commented out for reference), didn't account for some registers which
1889 were left marked 'not free' after a pointer operation. The change
1890 reduces register usage a lot in some cases

4248 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4250 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4252 * device/lib/printf_large.c: removed inline assembly for portability and
4253 readability. Use printf_fast if speed or size are more important.
4254 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4255 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4257 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4259 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4260 prevent compiler warning
4262 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4264 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4265 moved to level 0 and declared as static. Also they are explicit
4266 placed in access bank. This was necessery because some times they
4267 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4268 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4269 optimizations. Currently only compare to unsigned char is implemented,
4270 * src/pic16/gen.c: added fReturnIdx array,
4271 * (struct resolvedIfx) is moved to gen.h and made public,
4272 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4273 * (aopForSym): added an optimization to directly store in stack of
4274 the operand of a SEND iCode,
4275 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4276 but as registers instead (AOP_REG) using the fReturnIdx array,
4277 * (pic16_freeAsmop): remove the freed register from the
4278 _G.sregsAlloc field,
4279 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4280 a compare of 'WREG',
4281 * (pic16_popGetTempRegCond): changed function prototype, now
4282 function takes also a bitVector argument v which holds the current
4283 set of registers that are allocated for stack access by aopForSym,
4284 registers allocated in aopForSym for accessing stack symbols are not
4285 any more part of the functions usedRegs field,
4286 * (genCall): some times aopOp is called for a stack variable to be
4287 send, aopForSym might perform the push, if this is true make sure
4288 that genCall doesn't push the variable twice by testing _G.resDirect,
4289 * (genFunction): changed testing for unspecified interrupt number
4290 from 256 to INTNO_UNSPEC,
4291 * modified selection scheme of frame pointer generation. Previously
4292 if function did use local registers a frame pointer was generated,
4293 now a frame pointer is generated only if function has arguments
4294 (that need PLUSW2 register access), or has stack arguments, or the
4295 compiler is not instructed to omit the frame pointer,
4296 * (genEndFunction): before restoring local registers that were saved
4297 in the function preamble, also restore the registers that *might*
4298 have been allocated for stack access,
4299 * (genRet): removed some old comments,
4300 * (genCmp, the active (RN's) version): added a call to the
4301 pic16_genCmp_special function to perform the compare with a more
4302 robust and optimized way,
4303 * (genInline): a feature has been added in inline code generation,
4304 which allows a wildcard variable substitution when writing inline
4305 assembly. Code is incomplete and experimental therefore undocumented,
4306 * (genCast): changed order of aopOp for result and right to allow
4307 aopForSym to directly load the result if possible,
4308 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,

4976 Adding support for replacing ljmps with sjmps in jumptables
4977 generated for switch statements. For now you need to set the
4978 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4979 Now 4 algorithms for mcs51 jumptable generation are used:
4980 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4981 addresses loaded pc-relative for up to 112 cases and stack-pushing
4982 target addresses loaded with offset from dptr for up to 256 cases.

5014 * added libc directory. The current version of LibC contains string
5015 functions, ctype functions and macros and some functions of the
5016 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5017 be extensively tested in the future. Standard disclaimer here.
5018 Library is not automatically build yet. But one can build it by

5030 * (pic16_storeForReturn): optimized return of 0,
5031 * (genCmp): experimental code for new genCmp which uses PIC18's
5032 special compare&skip instructions. Initial tests fail some times
5033 with variables grater than 1 byte in size, so new code is disabled,
5034 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5036 * (genCast): began a fix to optimize the casting of a bit to another
5037 bit, now assigning a bitfield to another bitfield will fail, sorry,

5046 and 1 for banking instruction,
5047 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5048 caused stop processing pCodes after a inline assembly block,
5049 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5051 registers when it shouldn't,
5052 * src/pic16/ralloc.c (allocReg): add preliminary support for
5053 supporting a limited set of temporary registers,
5055 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5061 (genFunction): optimize RECEIVE iCodes in reentrant functions
5063 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8063 loaded with the linker search paths (-L arguments) and the libraries
8064 to be linked with the current source (-l arguments). Changes
8065 currently will affect only the pic16 port.
8066 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8067 include path the port specific paths and port specific libraries,
8068 * gplink command now contains the $3 argument,
8069 * src/pic16/device.h,
8070 * src/pic16/device.c,: structure PIC_device is made public and

8086 Documenting changes from previous commits.
8087 * configure.in (version 1.56),
8088 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8089 when generating output files to configure the pic16 library,
8090 but now I've commented it out, since gputils aren't installed in the
8091 SF compile farm, so library won't compile
8093 * device/lib/Makefile.in (version 1.56): initially I've added in
8094 target 'all' the prerequestive 'model-pic16' so it compiled the
8095 pic16 library, but now I've commented it out for the same reasons
8097 * added targets 'model-pic16' and 'objects-pic16' to compile the
8099 * added target 'port-specific-objects-pic16' to handle the
8100 generated libraries and copy them into the build/ directory
8101 * added target 'clean-intermediate-pic16' to clean intermediate
8102 files into pic16 directory
8103 * in target 'installdirs' added line to create directory pic16 in

8107 added lines to copy all header files to installation path,
8108 * in target 'installdirs' added line create directory for pic16
8109 headers in the installation path

8314 arguments via -W option
8315 * src/pic16/main.c: added $l in _asmCmd, changed extension for
8316 object file from '.rel' to '.o' in port->linker structure,
8317 changed size of fptr from 2 to 3 in port structure

8348 * src/SDCCast.c (decorateType),
8349 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
8350 LEFT_OP (left shift)
8352 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8354 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8355 (default behaviour).
8357 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8359 A python script to validate compiler diagnostic messages. It can be
8360 used to verify that sdcc complains about bad c source code and
8361 gives a good location of the error.
8362 * support/valdiag/Makefile,
8363 * support/valdiag/valdiag.py,
8364 * support/valdiag/tests/*
8366 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8377 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8379 * src/common.h: added ifndef/define/endif macros
8380 around the header file.
8381 Bug reported from Jesus Calvino-Fraga
8383 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8385 * sdcc.spec: updated
8386 * device/include/Makefile.in: don't install CVS directories
8387 * device/lib/Makefile.in: added removal of CVS directories after install
8388 * doc/Makefile: fixed install, added local_icons
8389 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8390 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8391 * src/ds390/gen.c (genRightShift): fixed bug #870788
8392 * src/SDCCast.c (decorateType): fixed bug #870781
8394 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8396 PIC16 port related changes:
8397 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8398 added variable stackPos,
8400 * gen.c: genCall, assignResultValue: added support for
8401 pushing/retrieving function parameters to/from stack,
8402 genFunction,genEndFunction: setup stack frame for the
8404 genAddrOf: will be changed according to bug 863624
8406 * added files genutils.c and genutils.h which contain gen*
8407 debugged and optimised functions extracted from gen.c
8409 * glue.c: added variable 'externs' which holds extern symbols,
8410 pic16emitRegularMap: is modified to properly handle relocatable
8411 symbols under the new scheme,
8412 pic16createInterruptVect: is modified
8413 pic16printPublics: is modified to emit 'global' assembler directives,
8414 added pic16_printExterns to print extern symbols,
8415 pic16glue: initializes stack/frame pointer in the beginning of
8416 the assembly output. Temporary hack, will be corrected later,
8417 because gplink yet does not support stack and SDCC does not
8418 yet support a type of crt0.o object to create the final binary.
8420 * Removed many lines that contain 8051 legacy code.
8421 * The code is finally placed under a 'code' directive.
8422 * Added port specific options.
8424 * _process_pragma: simplified since now we do not need *special*
8425 include file to define SFR registers. But a separate header
8426 will be needed. This will be developed later.
8427 * _pic16_parseOptions: added, parses port specific options:
8428 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8429 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8430 --preplace-udata-with=
8432 * _pic16_setDefaultOptions: modified to initialize section names,
8433 but hack is temporarly out of order since it needs improvement.
8434 * _pic16_genAssemblerPreamble: configuration words are emitted by
8435 their address instead of their name. This part is incomplete and
8436 supports only the 18Fxx2 devices. Other devices will emit an error
8437 during assembly since they do not contain the same set of config
8439 * _pic16_genIVT: is modified,
8441 * pcode.c: added definitions for some hardware registers that are needed
8443 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8444 All PCI entries are updated. Now LFSR is supported.
8445 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8446 * added pic16_newpCodeOpLit2 to support instructions with
8447 two literal arguments
8448 * pic16_pCode2str: corrected code that emits assembler instructions
8449 with two literal operands and those that have an access bit modifier
8450 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8451 this fixes a bug which caused some labels to be lost, when an
8452 assembler directive was added, i.e. banksel,
8453 * pic16_FixRegisterBanking: improved logic that causes the insertion
8455 * InlineFunction: functions that are called once, are not any more
8456 inlined. This can be a port option in the future,
8458 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8460 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8461 hold the corresponding uninitialized symbols,
8462 * pic16_allocProcessorRegister: registers have explicit marked the
8464 * pic16_allocInternalRegister: registers are explicit marked as
8466 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8467 processing list, so bit registers were lost,
8470 * ralloc.h: added field 'accessBank' and original symbol operand
8471 in register definition,
8472 * removed the field isMapped from register definition,
8474 ** Several functions have been removed from various sources:
8475 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8476 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8477 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8478 pic16_assignRelocatableRegisters
8480 ** others have been introduced:
8481 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8482 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8484 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8486 * support/scripts/inc2h.pl: changed definition of BIT_AT
8487 to emit 'sbit at' instead of 'bit at'. This was a request.
8489 PIC16 port related preliminary changes:
8490 * gen.c: prefixed function popRegFromString with
8491 pic16_ and all references to it corrected
8492 * pcode.c: all pic16_pc_* hardware registers prefixed
8493 with underscore (_),
8494 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8495 * ralloc.c: newReg(): when register is REG_SFR then
8496 set address to rIdx,
8497 pic16_allocProcessorRegister(): marks register wasUsed=0
8498 pic16_writeUsedRegs(): added a call to assign processor
8499 registers via pic16_assignFixedRegisters
8501 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8503 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8504 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8505 variables in unused register banks. Also the SSEG is placed
8506 wherever there is enough space for it, and IDATA can be anywhere
8507 in internal RAM. For now compile using -Wl-Y[stack_size].
8508 The mem file is different for this option as well, since it
8509 makes no sense of talking about DSEG lenght.
8511 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8513 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8514 in certain cases, e.g. when ROM assignment, patch provided
8515 from Albert den Haan.
8517 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8756 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8758 * src/SDCCast.c (decorateType): disabled a transformation I added in
8759 revision 1.188 (access to fields of a structure at an absolute address);
8760 it breaks with bitfields, extern declarations, and gcse analysis.
8761 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8762 could be assigned through a pointer, so don't complain.
8763 * src/SDCCast.c (astErrors),
8765 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
8767 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

8773 pre-processor macro, i.e. -DMCU=p18f452
8774 * src/pic16/ralloc.c: renamed packRegisters to pic16_packRegisters,
8775 and modified to handle 'cast' icode similarly to '=' icode

9518 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9519 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9520 fetching of the pointer
9521 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9522 copied from genNearPointerSet()
9523 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9524 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9525 If they pop r0/r1 they must be called in the opposite order than aopOp().
9526 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9527 (resp. --stack-auto), prepared for --xstack

9538 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9540 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9541 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9542 type for bits was changed. It resulted in bit variables becoming
9543 global, which is not permitted in PIC 14 assembly output.
9545 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9547 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9560 A few small changes that speed up the peephole optimizer.
9564 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9566 Try to make the peephole optimizer smarter by maintaining
9567 an association between the assembly source code and the
9568 iCodes that originated them. Put this information to use
9569 with a new peephole rule condition "notVolatile" so that
9570 the rules can be aggressive yet still safe.
9575 * src/mcs51/peeph.def
9577 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9581 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9582 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9583 if the left or right operand symbols have the accuse flag set.
9585 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9587 Changed the type of the result of the ! (NOT) operator to char;
9588 previously it returned the same type as the source. This allows
9589 us to eliminate all the genFloatNot functions (all of its target
9590 implementations were very buggy) since !float can use the same
9593 * src/SDCCicode.c (ast2iCode): ! returns char

9602 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9603 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9604 during interrupts. Ensure WSAVE is located at a shared bank address.
9605 2. Fixed page selection in some places
9606 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9607 the registers name strings.
9608 4. Fixed "signed / unsigned compare" compiler warnings.
9609 5. The PIC port manages its own allocation of the general purpose
9610 registers, but makes no attempt to reuse them. As a result when
9611 compiling it soon runs out of general purpose registers. Some
9612 additional code was added to the files pcode.c and device.c to walk
9613 through the function call tree and rename the registers so that they
9623 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9624 genPlus() & genMinus() when the result is the same as left or right

9630 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9632 Made bitfield a distinct type from bit so that bitfields
9633 convert as per ANSI C and bits retain their traditional
9634 boolean style behaviour. Implemented bitfield support in
9642 * src/ds390/gen.c: bit v bitfield split
9643 * src/z80/gen.c: New support for bitfields
9644 * support/regression/tests/bitfields.c: reenabled z80,
9647 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9649 Rules 246.x, 247.x relate to bitfields, the others speed up
9650 access to xdata mapped I/O devices.
9652 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9654 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9656 Cleaned up genPackBits and genUnpackBits and added two helper
9657 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9658 for literal assignments in genPackBits (thanks to Frieder for
9664 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9666 Fixed bug #748310 (pointer to function type mishandled when the
9667 function name is omitted). Also fixed a SIGSEGV when a function
9668 attribute (reentrant, etc) is used on a non-function or on a
9669 function but misplaced before the parameter list.
9671 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9673 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9674 * support/Util/SDCCerr.h,

9696 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9698 Made the constant following the "interrupt" keyword optional. If
9699 omitted, the function will not automatically be given an entry
9700 in the interrupt vector table (similar to #pragma NOIV, but
9701 less syntacticly kludgy). The interrupt number is also now
9702 range checked. Also fixed a bug in the high order bit example

9718 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9720 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9721 be re-activated by defining REDUCE_LITERALS)
9722 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9723 unsigned, but are signed by default
9724 * src/SDCCval.c (constVal): rearranged
9725 * src/SDCCval.c (valMod): preliminary fix
9726 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10233 messages from optionsTable when a port is not configured, added
10234 support for the PIc16 port in the ports table, when executing
10235 the compiler with no port specified on command line, a default
10236 port is selected with the new macro DEFAULT_PORT which is
10237 defined in port.h, in setDefaultOptions() linkOptions is removed
10238 from initialization assignment, since now it is a set,
10239 parseCmdLine uses setParseWithComma for linkOptions, in
10240 linkEdit() linkOptions are accessed with new function indexSet()
10241 which returns the i'th item of a set variable. See SDCCset.c, in
10242 linkEdit() when calling buildCmdLine(), added linkOptions as
10243 last argument. Now users can pass arguments to gplink via the
10244 -Wl option, main() uses pic16glue() to glue up pic16 programs

10258 gpasm complaining and test the linkage with gplink, _linkCmd and
10259 _asmCmd changed to be more gplink and gpasm friendly
10260 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10261 produced an error when parsed, peep rule 12 is added to utilize
10262 movff, but it is commented out since the pCode does not support
10263 yet a command with 2 address arguments

11328 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11330 * in /sdcc/as/mcs51/ changed these files in order to create an
11331 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11332 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11333 following files to include the previous two files: aslink.dsp,
11334 Makefile.aslink, Makefile.bcc, and Makefile.in.
11336 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11337 .adb instead of .cdb
11339 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11341 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11342 value from option --iram-size.
11344 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11346 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11349 2002-09-18 <wiml AT hhhh.org>
11351 * SDCClrange.h: exposed setFromRange() and setToRange()
11352 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11353 packRegsForAccUse() (bug 542397)
11354 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11355 multiple times and emitting the fetch operations more than once
11356 added aopGetUsesAcc() function to allow binary operators to
11357 fetch their operands in the correct order; made genMinus() emit
11358 compact code for X = LITERAL - Y
11360 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11361 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11362 sprintf() in line 1267.
11364 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11365 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11368 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11369 Changes to aslink (All the changes are marked with 'JCF'):
11371 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11374 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11375 area BSEG. Also moves, if possible, the DATA area down into the internal
11376 ram so more space is available.
11378 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11381 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11382 not bytes. Function summary() which creates a memory usage summary
11383 file with extension .mem. Reports of overlaping stack and small stack
11384 size. If the space for the stack is less than 16 bytes aslink trows a
11387 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11388 the 8051. Option 'y' for memory summary output file.
11390 Changes to sdcc (All the changes are marked with 'JCF'):
11392 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11394 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11395 overlaying area for it (uses RegBankUsed[4]).
11397 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11398 bank zero as used by default. By default aslink locates the stack
11399 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11400 the creation of the .mem file. Delegates the allocation of data area
11401 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11402 the begining of the stack area to aslink.
11404 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11405 glue() in SDCCglue.c creates an area for it.
11407 2002-09-03 Borut Razem <borut.razem AT siol.net>
11408 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11409 sdcc/src/pic/glue.c:
11410 introduced atexit() handler for teporay files removal in case of
11411 errors, assertions, ...
11413 2002-08-29 Borut Razem <borut.razem AT siol.net>
11414 * sdcc/support/cpp2/auto-host_vc_in.h:
11415 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11416 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11417 Maybe there is a similar problem with BORLANDC? It should be checked!
11419 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11420 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11421 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11422 was not executed, and the compiler (cl) launched a warning:
11423 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11425 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11426 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11428 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11429 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11431 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11432 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11433 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11434 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11435 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11436 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11437 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11438 - added Release configuration in VS projects
11439 - review of compiler an linker options
11440 - VC .exe files are generated in bin_vc directory, not to interfere
11441 with binaries generated from other projects (cygwin, mingw, bcc ...)
11443 * sdcc/src/yacc.dsp: added
11445 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11446 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11447 and insert the version number definitions from .version
11449 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11451 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11452 added - genarate auto-host.h using auto-host_vc_in.h as template
11455 removed from CVS, generated automatically
11457 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11458 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11460 2002-08-11 Borut Razem <borut.razem AT siol.net>
11461 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11463 2002-08-10 Borut Razem <borut.razem AT siol.net>
11464 * src/SDCCmain.c (main):
11465 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11466 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11467 The consequence was that some temporary files were not removed.
11470 unification of code in functions tempfilename() and tempfile():
11471 function tempnam() is defined in Visual Studio 6.0 and .NET
11473 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11475 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11476 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11477 - removed compiler command line option /WX: Treats all warnings as errors
11478 - update a list of source files, included into the project
11480 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11481 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11482 changed project type to Generic Project so that can be correcly converted to VS.NET project
11484 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11486 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11488 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11490 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11491 added return 0 statements after assert() to make compiler happy
11493 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11494 added newline in the def file to keep MSC compiler satisfied
11496 * sdcc/src/z80/gen.c:
11497 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11498 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11499 - solved MSC error in function aopDump()
11501 * sdcc_vc.h: define PREFIX as "\\sdcc"
11503 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>

11507 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11508 - Rewrote the register banking algorithm.
11509 - Added pCode live-range analysis to registers (for now, only non-used and
11510 singly-used registers optimized away)
11512 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11514 * 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.

11545 * src/SDCCval.c: fixed bug #532436
11547 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11549 Added "char *Processor" field to the port structure.
11552 Added -p option. Allows port dependent processor to be specified.
11555 Initialized the new field char *Processor field to NULL in all ports
11558 Compiler generated registers for interrupt context saving
11559 were not getting allocated.
11561 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11564 Fixed left shift. Will promote the left side of a left shift
11565 if a) left shifting more than size of operand or b) when assigned
11566 to something size > size of left side

11679 Previous fix was not good. basic blocks that have "break" or "return" are
11680 not really partof a loop , but live ranges used in these blocks should
11681 be live thru the entire loop, so set partOfLoop but don't add them to
