1824 2004-01-27 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1826 * ChangeLog: changed "@" to " AT " in hopes of reducing spam and
1827 virus/worm forged address usage.
1829 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
1831 Fixed promotion, it should be done on AST level:
1832 * src/SDCCast.c (addCast): added promotion to int
1833 (decorateType): updated call to upCast()
1834 * src/SDCCicode.c (geniCodeLeftShift): removed call to
1835 usualUnaryConversions()
1837 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
1839 * support/regression/tests/literalop.c (mulWrapper): Added a
1840 wrapper to remove integer overflow warnings.
1842 * support/regression/tests/float_trans.c: Made work on host.
1844 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
1847 * support/regression/generate-cases.py (main): Changed from inline
1850 * doc/Makefile (install): Changed to depth first to get rid of
1851 missing directory install warning.
1853 * as/Makefile (install-doc): Made work on Mac.
1855 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
1857 * src/SDCCast.c: added an additional type flow in decorateType() of
1858 opposite direction, see feature request #860006; it's enabled at runtime
1859 by setting the environment variable SDCC_NEWTYPEFLOW
1860 * src/SDCCast.h: changed prototype of decorateType()
1861 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
1862 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
1863 'char' to 'int' can be omitted, if both operands are 'unsigned char';
1864 see feature request #877103
1865 * src/SDCCval.c: updated call of decorateType()
1866 (valBitwise): fixed bug #882876
1867 (valMinus): added promotion
1868 (valLogicAndOr): result is unsigned
1869 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
1870 * src/SDCCsymt.c (computeType),
1871 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'

1893 * src/pic/ralloc.h: applied patch from Slade Rich;
1894 added support for multiple code pages and multiple RAM banks on the
1895 PIC 14 port. The ASM files now no longer simply assume all the
1896 code / RAM are in the same page / bank. This means the linker can
1897 safely allocate code/RAM of separate ASM files to different pages/banks.
1898 * doc/sdccman.lyx: added Slade's tips
1899 * src/mcs51/peeph.def: fixed bug #880768

1911 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
1912 strtof is not part of C89 and isn't included with Mac OS X.
1914 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1916 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

1941 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
1943 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
1944 loaded with the linker search paths (-L arguments) and the libraries
1945 to be linked with the current source (-l arguments). Changes
1946 currently will affect only the pic16 port.
1947 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1948 include path the port specific paths and port specific libraries,
1949 * gplink command now contains the $3 argument,
1950 * src/pic16/device.h,
1951 * src/pic16/device.c,: structure PIC_device is made public and
1952 renamed to PIC16_device, the same for variable Pics which is renamed

1967 Documenting changes from previous commits.
1968 * configure.in (version 1.56),
1969 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1970 when generating output files to configure the pic16 library,
1971 but now I've commented it out, since gputils aren't installed in the
1972 SF compile farm, so library won't compile
1974 * device/lib/Makefile.in (version 1.56): initially I've added in
1975 target 'all' the prerequestive 'model-pic16' so it compiled the
1976 pic16 library, but now I've commented it out for the same reasons
1978 * added targets 'model-pic16' and 'objects-pic16' to compile the
1980 * added target 'port-specific-objects-pic16' to handle the
1981 generated libraries and copy them into the build/ directory
1982 * added target 'clean-intermediate-pic16' to clean intermediate
1983 files into pic16 directory
1984 * in target 'installdirs' added line to create directory pic16 in
1985 the installation path

1988 added lines to copy all header files to installation path,
1989 * in target 'installdirs' added line create directory for pic16
1990 headers in the installation path

2005 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2006 option so that it actually works. Made it specific to the z80, since
2007 the gbz80 doesn't have these kinds of I/O ports.
2009 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2011 * device/include/z180.h,

2033 Mainly changes to support compilation of the device libraries
2034 * src/pic16/device.c: stack is allocated via symbol and not
2035 via literal number. The symbol is placed in the corresponding
2036 position of the data ram
2037 * (pic16_dump_section): relocatable and absolute uninitialized
2038 data are now emitted in sorted order to reduce section naming,
2039 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2040 weren't marked as being in the access bank,
2042 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2044 Added portion of GNU PIC Library under the directory
2045 device/include/pic16 and device/lib/pic16. These files
2046 contain the declarations of SFRs for the PIC18Fxx2 devices.
2047 The directory is initialized via configure from toplevel.

2077 all over. Telling LaTeX to be less strict with word spacing
2078 to better keep the right margin. Changed some notes about
2079 maintainance of the ports in section 3.2.1 - is it OK like this?
2081 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2121 * src/pic16/peeph.def: all peepholes with movff are commented out,
2122 because there is a problem in the pcode peep optimizer,
2123 * src/pic16/ralloc.c: the register allocator can now reuse local

2125 * src/pic16/ralloc.h: added flag isLocal in structure regs,
2127 Added file src/pic16/NOTES with information about program writing on
2128 the current port version.

2262 Bug reported from Jesus Calvino-Fraga
2264 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2266 * sdcc.spec: updated
2267 * device/include/Makefile.in: don't install CVS directories

2270 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2271 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2272 * src/ds390/gen.c (genRightShift): fixed bug #870788
2273 * src/SDCCast.c (decorateType): fixed bug #870781
2275 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2277 PIC16 port related changes:
2278 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2279 added variable stackPos,
2281 * gen.c: genCall, assignResultValue: added support for
2282 pushing/retrieving function parameters to/from stack,
2283 genFunction,genEndFunction: setup stack frame for the
2285 genAddrOf: will be changed according to bug 863624
2287 * added files genutils.c and genutils.h which contain gen*
2288 debugged and optimised functions extracted from gen.c
2290 * glue.c: added variable 'externs' which holds extern symbols,
2291 pic16emitRegularMap: is modified to properly handle relocatable
2292 symbols under the new scheme,
2293 pic16createInterruptVect: is modified
2294 pic16printPublics: is modified to emit 'global' assembler directives,
2295 added pic16_printExterns to print extern symbols,
2296 pic16glue: initializes stack/frame pointer in the beginning of
2297 the assembly output. Temporary hack, will be corrected later,
2298 because gplink yet does not support stack and SDCC does not
2299 yet support a type of crt0.o object to create the final binary.
2301 * Removed many lines that contain 8051 legacy code.
2302 * The code is finally placed under a 'code' directive.
2303 * Added port specific options.
2305 * _process_pragma: simplified since now we do not need *special*
2306 include file to define SFR registers. But a separate header
2307 will be needed. This will be developed later.
2308 * _pic16_parseOptions: added, parses port specific options:
2309 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2310 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2311 --preplace-udata-with=
2313 * _pic16_setDefaultOptions: modified to initialize section names,
2314 but hack is temporarly out of order since it needs improvement.
2315 * _pic16_genAssemblerPreamble: configuration words are emitted by
2316 their address instead of their name. This part is incomplete and
2317 supports only the 18Fxx2 devices. Other devices will emit an error
2318 during assembly since they do not contain the same set of config
2320 * _pic16_genIVT: is modified,
2322 * pcode.c: added definitions for some hardware registers that are needed
2324 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2325 All PCI entries are updated. Now LFSR is supported.
2326 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2327 * added pic16_newpCodeOpLit2 to support instructions with
2328 two literal arguments
2329 * pic16_pCode2str: corrected code that emits assembler instructions
2330 with two literal operands and those that have an access bit modifier
2331 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2332 this fixes a bug which caused some labels to be lost, when an
2333 assembler directive was added, i.e. banksel,
2334 * pic16_FixRegisterBanking: improved logic that causes the insertion
2336 * InlineFunction: functions that are called once, are not any more
2337 inlined. This can be a port option in the future,
2339 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2341 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2342 hold the corresponding uninitialized symbols,
2343 * pic16_allocProcessorRegister: registers have explicit marked the
2345 * pic16_allocInternalRegister: registers are explicit marked as
2347 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2348 processing list, so bit registers were lost,
2351 * ralloc.h: added field 'accessBank' and original symbol operand
2352 in register definition,
2353 * removed the field isMapped from register definition,
2355 ** Several functions have been removed from various sources:
2356 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2357 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2358 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2359 pic16_assignRelocatableRegisters
2361 ** others have been introduced:
2362 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2363 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2365 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2367 * support/scripts/inc2h.pl: changed definition of BIT_AT
2368 to emit 'sbit at' instead of 'bit at'. This was a request.
2370 PIC16 port related preliminary changes:
2371 * gen.c: prefixed function popRegFromString with
2372 pic16_ and all references to it corrected
2373 * pcode.c: all pic16_pc_* hardware registers prefixed
2374 with underscore (_),
2375 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2376 * ralloc.c: newReg(): when register is REG_SFR then
2377 set address to rIdx,
2378 pic16_allocProcessorRegister(): marks register wasUsed=0
2379 pic16_writeUsedRegs(): added a call to assign processor
2380 registers via pic16_assignFixedRegisters
2382 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2384 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2385 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2386 variables in unused register banks. Also the SSEG is placed
2387 wherever there is enough space for it, and IDATA can be anywhere
2388 in internal RAM. For now compile using -Wl-Y[stack_size].
2389 The mem file is different for this option as well, since it
2390 makes no sense of talking about DSEG lenght.
2392 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2394 * src/SDCClrange.c: fixed bug 869095 that caused segfault

2639 * src/SDCCast.c (decorateType): disabled a transformation I added in
2640 revision 1.188 (access to fields of a structure at an absolute address);
2641 it breaks with bitfields, extern declarations, and gcse analysis.
2642 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
2643 could be assigned through a pointer, so don't complain.

2751 xdata initialization slightly shorter
2753 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3400 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3401 fetching of the pointer
3402 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3403 copied from genNearPointerSet()
3404 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3405 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

3421 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3422 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3423 type for bits was changed. It resulted in bit variables becoming
3424 global, which is not permitted in PIC 14 assembly output.
3426 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3428 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3441 A few small changes that speed up the peephole optimizer.
3445 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3447 Try to make the peephole optimizer smarter by maintaining
3448 an association between the assembly source code and the
3449 iCodes that originated them. Put this information to use
3450 with a new peephole rule condition "notVolatile" so that
3451 the rules can be aggressive yet still safe.
3456 * src/mcs51/peeph.def
3458 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3462 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3463 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3464 if the left or right operand symbols have the accuse flag set.
3466 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3468 Changed the type of the result of the ! (NOT) operator to char;
3469 previously it returned the same type as the source. This allows
3470 us to eliminate all the genFloatNot functions (all of its target
3471 implementations were very buggy) since !float can use the same
3474 * src/SDCCicode.c (ast2iCode): ! returns char

3483 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3484 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3485 during interrupts. Ensure WSAVE is located at a shared bank address.
3486 2. Fixed page selection in some places
3487 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3488 the registers name strings.
3489 4. Fixed "signed / unsigned compare" compiler warnings.
3490 5. The PIC port manages its own allocation of the general purpose
3491 registers, but makes no attempt to reuse them. As a result when
3492 compiling it soon runs out of general purpose registers. Some
3493 additional code was added to the files pcode.c and device.c to walk
3494 through the function call tree and rename the registers so that they
3504 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3505 genPlus() & genMinus() when the result is the same as left or right

3511 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3513 Made bitfield a distinct type from bit so that bitfields
3514 convert as per ANSI C and bits retain their traditional
3515 boolean style behaviour. Implemented bitfield support in
3523 * src/ds390/gen.c: bit v bitfield split
3524 * src/z80/gen.c: New support for bitfields
3525 * support/regression/tests/bitfields.c: reenabled z80,
3528 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3530 Rules 246.x, 247.x relate to bitfields, the others speed up
3531 access to xdata mapped I/O devices.
3533 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3535 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3537 Cleaned up genPackBits and genUnpackBits and added two helper
3538 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3539 for literal assignments in genPackBits (thanks to Frieder for
3545 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3547 Fixed bug #748310 (pointer to function type mishandled when the
3548 function name is omitted). Also fixed a SIGSEGV when a function
3549 attribute (reentrant, etc) is used on a non-function or on a
3550 function but misplaced before the parameter list.
3552 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3554 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
3555 * support/Util/SDCCerr.h,
3556 * support/Util/SDCCerr.c: Added func attr misuse error msg

3577 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3579 Made the constant following the "interrupt" keyword optional. If
3580 omitted, the function will not automatically be given an entry
3581 in the interrupt vector table (similar to #pragma NOIV, but
3582 less syntacticly kludgy). The interrupt number is also now
3583 range checked. Also fixed a bug in the high order bit example
3590 * support/Util/SDCCerr.c
3591 * support/Util/SDCCerr.h
3594 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
3596 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
3597 * src/SDCCicode.c (operandOperation): rewritten some ops
3598 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
3599 * src/SDCCsymt.c (computeType): literals are handled the same way as any
3601 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
3602 be re-activated by defining REDUCE_LITERALS)
3603 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
3604 unsigned, but are signed by default
3605 * src/SDCCval.c (constVal): rearranged
3606 * src/SDCCval.c (valMod): preliminary fix
3607 * src/SDCCval.c (valCastLiteral): use TYPE_* types

3649 constants are unsigned; added recognition of "u" flag for unsigned
3650 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
3651 * src/SDCCval.c (valDiv, valMod): fixed signdness
3652 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
3653 signedness of modulo, left and right shift

4104 it can be defined with CFLAGS when running configure
4105 * src/SDCCmain.c: fixed compiling + linking with object files
4107 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

4110 added --disable-pic16-port
4111 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4112 * src/SDCCmain.c: linkOptions is changed to set *,
4113 added if/endif conditional macros to remove options help
4114 messages from optionsTable when a port is not configured, added
4115 support for the PIc16 port in the ports table, when executing
4116 the compiler with no port specified on command line, a default
4117 port is selected with the new macro DEFAULT_PORT which is
4118 defined in port.h, in setDefaultOptions() linkOptions is removed
4119 from initialization assignment, since now it is a set,
4120 parseCmdLine uses setParseWithComma for linkOptions, in
4121 linkEdit() linkOptions are accessed with new function indexSet()
4122 which returns the i'th item of a set variable. See SDCCset.c, in
4123 linkEdit() when calling buildCmdLine(), added linkOptions as
4124 last argument. Now users can pass arguments to gplink via the
4125 -Wl option, main() uses pic16glue() to glue up pic16 programs

4137 * src/pic16/glue.c: commented out some error producing lines
4138 * src/pic16/main.c: __config directives are commented out to stop
4139 gpasm complaining and test the linkage with gplink, _linkCmd and
4140 _asmCmd changed to be more gplink and gpasm friendly
4141 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4142 produced an error when parsed, peep rule 12 is added to utilize
4143 movff, but it is commented out since the pCode does not support
4144 yet a command with 2 address arguments
4146 2003-05-18 <johan AT balder>
4148 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4149 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4173 * src/SDCCmain.c: fixed the problem with searching the DATADIR as the last resort on *nix
4175 2003-05-11 Borut Razem <borut.razem AT siol.net>
4177 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4178 the path of bin directory, so that PATH is the only env. variable, which has to be set
4179 in case of standard installation.
4180 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5237 added aopGetUsesAcc() function to allow binary operators to
5238 fetch their operands in the correct order; made genMinus() emit
5239 compact code for X = LITERAL - Y
5241 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5242 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5243 sprintf() in line 1267.
5245 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5246 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5249 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5250 Changes to aslink (All the changes are marked with 'JCF'):
5252 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5255 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5256 area BSEG. Also moves, if possible, the DATA area down into the internal
5257 ram so more space is available.
5259 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5262 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5263 not bytes. Function summary() which creates a memory usage summary
5264 file with extension .mem. Reports of overlaping stack and small stack
5265 size. If the space for the stack is less than 16 bytes aslink trows a
5268 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5269 the 8051. Option 'y' for memory summary output file.
5271 Changes to sdcc (All the changes are marked with 'JCF'):
5273 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5275 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5276 overlaying area for it (uses RegBankUsed[4]).
5278 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5279 bank zero as used by default. By default aslink locates the stack
5280 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5281 the creation of the .mem file. Delegates the allocation of data area
5282 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5283 the begining of the stack area to aslink.
5285 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5286 glue() in SDCCglue.c creates an area for it.
5288 2002-09-03 Borut Razem <borut.razem AT siol.net>
5289 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5290 sdcc/src/pic/glue.c:
5291 introduced atexit() handler for teporay files removal in case of
5292 errors, assertions, ...
5294 2002-08-29 Borut Razem <borut.razem AT siol.net>
5295 * sdcc/support/cpp2/auto-host_vc_in.h:
5296 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5297 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5298 Maybe there is a similar problem with BORLANDC? It should be checked!
5300 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5301 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5302 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5303 was not executed, and the compiler (cl) launched a warning:
5304 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5306 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5307 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5309 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5310 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5312 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5313 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5314 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5315 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5316 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5317 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5318 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5319 - added Release configuration in VS projects
5320 - review of compiler an linker options
5321 - VC .exe files are generated in bin_vc directory, not to interfere
5322 with binaries generated from other projects (cygwin, mingw, bcc ...)
5324 * sdcc/src/yacc.dsp: added
5326 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5327 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5328 and insert the version number definitions from .version
5330 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5332 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5333 added - genarate auto-host.h using auto-host_vc_in.h as template
5336 removed from CVS, generated automatically
5338 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5339 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5341 2002-08-11 Borut Razem <borut.razem AT siol.net>
5342 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5344 2002-08-10 Borut Razem <borut.razem AT siol.net>
5345 * src/SDCCmain.c (main):
5346 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5347 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5348 The consequence was that some temporary files were not removed.
5351 unification of code in functions tempfilename() and tempfile():
5352 function tempnam() is defined in Visual Studio 6.0 and .NET
5354 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5356 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5357 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5358 - removed compiler command line option /WX: Treats all warnings as errors
5359 - update a list of source files, included into the project
5361 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5362 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5363 changed project type to Generic Project so that can be correcly converted to VS.NET project
5365 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5367 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5369 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5371 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5372 added return 0 statements after assert() to make compiler happy
5374 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5375 added newline in the def file to keep MSC compiler satisfied
5377 * sdcc/src/z80/gen.c:
5378 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5379 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5380 - solved MSC error in function aopDump()
5382 * sdcc_vc.h: define PREFIX as "\\sdcc"
5384 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5385 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5388 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
5389 - Rewrote the register banking algorithm.
5390 - Added pCode live-range analysis to registers (for now, only non-used and
5391 singly-used registers optimized away)
5393 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis

5424 2002-03-28 Johan Knol <johan AT balder>
5426 * src/SDCCval.c: fixed bug #532436
5428 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5430 Added "char *Processor" field to the port structure.
5433 Added -p option. Allows port dependent processor to be specified.
5436 Initialized the new field char *Processor field to NULL in all ports
5439 Compiler generated registers for interrupt context saving
5440 were not getting allocated.
5442 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5445 Fixed left shift. Will promote the left side of a left shift
5446 if a) left shifting more than size of operand or b) when assigned
5447 to something size > size of left side
5449 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5451 tons of changes. Register allocation has been
5452 rewritten. Added customization for the various PICs. Flow

5557 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
5559 * sdcc/src/SDCCloop.c:
5560 Previous fix was not good. basic blocks that have "break" or "return" are
5561 not really partof a loop , but live ranges used in these blocks should
5562 be live thru the entire loop, so set partOfLoop but don't add them to
5565 2002-02-21 <johan AT FRIJA>
5567 * src/SDCCcse.c: fixed bug #514308
5569 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
5572 Fixed BUG #519583. If a conditional block ended in a return/break
5573 statement inside a loop, it was not being considered part of the loop.
5575 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
5577 2002-02-10 Karl Bongers <karl AT turbobit.com>
5580 Fixed up SDCDB debugger somewhat. Updated debugger/README
5581 with lots of comments and notes.
5583 * device/examples/test2.c:
5584 Fix bug, "red" variable not being initialized(compiler complained).

5588 for use as a multiple module SDCDB test case.
5590 * sim/ucsim/cmd.src/cmdset.cc:
5591 Took out debug printfs in ucsim "next" command.
5594 Karl and Johan start ucsim XA support. Most dissassembly working,
