1816 (decorateType): updated call to upCast()
1817 * src/SDCCicode.c (geniCodeLeftShift): removed call to
1818 usualUnaryConversions()
1820 2004-01-26 Michael Hope <michaelh AT juju.net.nz>

1827 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
1830 * support/regression/generate-cases.py (main): Changed from inline
1833 * doc/Makefile (install): Changed to depth first to get rid of
1834 missing directory install warning.
1836 * as/Makefile (install-doc): Made work on Mac.
1838 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
1840 * src/SDCCast.c: added an additional type flow in decorateType() of
1841 opposite direction, see feature request #860006; it's enabled at runtime
1842 by setting the environment variable SDCC_NEWTYPEFLOW
1843 * src/SDCCast.h: changed prototype of decorateType()
1844 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
1845 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
1846 'char' to 'int' can be omitted, if both operands are 'unsigned char';
1847 see feature request #877103
1848 * src/SDCCval.c: updated call of decorateType()
1849 (valBitwise): fixed bug #882876
1850 (valMinus): added promotion
1851 (valLogicAndOr): result is unsigned
1852 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
1853 * src/SDCCsymt.c (computeType),
1854 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
1855 must not cause an unsigned operation

1876 * src/pic/ralloc.h: applied patch from Slade Rich;
1877 added support for multiple code pages and multiple RAM banks on the
1878 PIC 14 port. The ASM files now no longer simply assume all the
1879 code / RAM are in the same page / bank. This means the linker can
1880 safely allocate code/RAM of separate ASM files to different pages/banks.
1881 * doc/sdccman.lyx: added Slade's tips
1882 * src/mcs51/peeph.def: fixed bug #880768

1924 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
1926 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
1927 loaded with the linker search paths (-L arguments) and the libraries
1928 to be linked with the current source (-l arguments). Changes
1929 currently will affect only the pic16 port.
1930 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1931 include path the port specific paths and port specific libraries,
1932 * gplink command now contains the $3 argument,
1933 * src/pic16/device.h,
1934 * src/pic16/device.c,: structure PIC_device is made public and
1935 renamed to PIC16_device, the same for variable Pics which is renamed

1950 Documenting changes from previous commits.
1951 * configure.in (version 1.56),
1952 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1953 when generating output files to configure the pic16 library,
1954 but now I've commented it out, since gputils aren't installed in the
1955 SF compile farm, so library won't compile
1957 * device/lib/Makefile.in (version 1.56): initially I've added in
1958 target 'all' the prerequestive 'model-pic16' so it compiled the
1959 pic16 library, but now I've commented it out for the same reasons
1961 * added targets 'model-pic16' and 'objects-pic16' to compile the
1963 * added target 'port-specific-objects-pic16' to handle the
1964 generated libraries and copy them into the build/ directory
1965 * added target 'clean-intermediate-pic16' to clean intermediate
1966 files into pic16 directory
1967 * in target 'installdirs' added line to create directory pic16 in
1968 the installation path

1988 * src/z80/main.c (_parseOptions): fixed the portmode= command line
1989 option so that it actually works. Made it specific to the z80, since
1990 the gbz80 doesn't have these kinds of I/O ports.
1992 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1994 * device/include/z180.h,

2021 data are now emitted in sorted order to reduce section naming,
2022 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2023 weren't marked as being in the access bank,
2025 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2027 Added portion of GNU PIC Library under the directory

2060 all over. Telling LaTeX to be less strict with word spacing
2061 to better keep the right margin. Changed some notes about
2062 maintainance of the ports in section 3.2.1 - is it OK like this?
2064 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2104 * src/pic16/peeph.def: all peepholes with movff are commented out,
2105 because there is a problem in the pcode peep optimizer,
2106 * src/pic16/ralloc.c: the register allocator can now reuse local

2258 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2260 PIC16 port related changes:
2261 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2262 added variable stackPos,
2264 * gen.c: genCall, assignResultValue: added support for
2265 pushing/retrieving function parameters to/from stack,
2266 genFunction,genEndFunction: setup stack frame for the
2268 genAddrOf: will be changed according to bug 863624
2270 * added files genutils.c and genutils.h which contain gen*
2271 debugged and optimised functions extracted from gen.c
2273 * glue.c: added variable 'externs' which holds extern symbols,
2274 pic16emitRegularMap: is modified to properly handle relocatable
2275 symbols under the new scheme,
2276 pic16createInterruptVect: is modified
2277 pic16printPublics: is modified to emit 'global' assembler directives,
2278 added pic16_printExterns to print extern symbols,
2279 pic16glue: initializes stack/frame pointer in the beginning of
2280 the assembly output. Temporary hack, will be corrected later,
2281 because gplink yet does not support stack and SDCC does not
2282 yet support a type of crt0.o object to create the final binary.
2284 * Removed many lines that contain 8051 legacy code.
2285 * The code is finally placed under a 'code' directive.
2286 * Added port specific options.
2288 * _process_pragma: simplified since now we do not need *special*
2289 include file to define SFR registers. But a separate header
2290 will be needed. This will be developed later.
2291 * _pic16_parseOptions: added, parses port specific options:
2292 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2293 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2294 --preplace-udata-with=
2296 * _pic16_setDefaultOptions: modified to initialize section names,
2297 but hack is temporarly out of order since it needs improvement.
2298 * _pic16_genAssemblerPreamble: configuration words are emitted by
2299 their address instead of their name. This part is incomplete and
2300 supports only the 18Fxx2 devices. Other devices will emit an error
2301 during assembly since they do not contain the same set of config
2303 * _pic16_genIVT: is modified,
2305 * pcode.c: added definitions for some hardware registers that are needed
2307 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2308 All PCI entries are updated. Now LFSR is supported.
2309 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2310 * added pic16_newpCodeOpLit2 to support instructions with
2311 two literal arguments
2312 * pic16_pCode2str: corrected code that emits assembler instructions
2313 with two literal operands and those that have an access bit modifier
2314 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2315 this fixes a bug which caused some labels to be lost, when an
2316 assembler directive was added, i.e. banksel,
2317 * pic16_FixRegisterBanking: improved logic that causes the insertion
2319 * InlineFunction: functions that are called once, are not any more
2320 inlined. This can be a port option in the future,
2322 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2324 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2325 hold the corresponding uninitialized symbols,
2326 * pic16_allocProcessorRegister: registers have explicit marked the
2328 * pic16_allocInternalRegister: registers are explicit marked as
2330 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2331 processing list, so bit registers were lost,
2334 * ralloc.h: added field 'accessBank' and original symbol operand
2335 in register definition,
2336 * removed the field isMapped from register definition,
2338 ** Several functions have been removed from various sources:
2339 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2340 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2341 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2342 pic16_assignRelocatableRegisters
2344 ** others have been introduced:
2345 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2346 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2348 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2350 * support/scripts/inc2h.pl: changed definition of BIT_AT
2351 to emit 'sbit at' instead of 'bit at'. This was a request.
2353 PIC16 port related preliminary changes:
2354 * gen.c: prefixed function popRegFromString with
2355 pic16_ and all references to it corrected
2356 * pcode.c: all pic16_pc_* hardware registers prefixed
2357 with underscore (_),
2358 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2359 * ralloc.c: newReg(): when register is REG_SFR then
2360 set address to rIdx,
2361 pic16_allocProcessorRegister(): marks register wasUsed=0
2362 pic16_writeUsedRegs(): added a call to assign processor
2363 registers via pic16_assignFixedRegisters
2365 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2367 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2368 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2369 variables in unused register banks. Also the SSEG is placed
2370 wherever there is enough space for it, and IDATA can be anywhere
2371 in internal RAM. For now compile using -Wl-Y[stack_size].
2372 The mem file is different for this option as well, since it
2373 makes no sense of talking about DSEG lenght.
2375 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2377 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2378 in certain cases, e.g. when ROM assignment, patch provided
2379 from Albert den Haan.

2620 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2622 * src/SDCCast.c (decorateType): disabled a transformation I added in
2623 revision 1.188 (access to fields of a structure at an absolute address);
2624 it breaks with bitfields, extern declarations, and gcse analysis.
2625 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
2626 could be assigned through a pointer, so don't complain.
2627 * src/SDCCast.c (astErrors),

3386 copied from genNearPointerSet()
3387 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3388 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

3404 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3405 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3406 type for bits was changed. It resulted in bit variables becoming
3407 global, which is not permitted in PIC 14 assembly output.
3409 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3411 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3415 Z80 and MCS51 linkers complaint if a public symbol is defined
3416 in more than one library module:
3420 * as/mcs51/Makefile.in
3422 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3424 A few small changes that speed up the peephole optimizer.
3428 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3430 Try to make the peephole optimizer smarter by maintaining
3431 an association between the assembly source code and the
3432 iCodes that originated them. Put this information to use
3433 with a new peephole rule condition "notVolatile" so that
3434 the rules can be aggressive yet still safe.
3439 * src/mcs51/peeph.def
3441 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3445 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3446 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3447 if the left or right operand symbols have the accuse flag set.
3449 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3451 Changed the type of the result of the ! (NOT) operator to char;
3452 previously it returned the same type as the source. This allows
3453 us to eliminate all the genFloatNot functions (all of its target
3454 implementations were very buggy) since !float can use the same
3457 * src/SDCCicode.c (ast2iCode): ! returns char
3458 * src/mcs51/gen.c (genNot, genNotFloat),
3459 * src/ds390/gen.c (genNot, genNotFloat),
3460 * src/z80/gen.c (genNot, genNotFloat),
3461 * src/pic/gen.c (genNot, genNotFloat),
3462 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
3464 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
3466 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3467 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3468 during interrupts. Ensure WSAVE is located at a shared bank address.
3469 2. Fixed page selection in some places
3470 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3471 the registers name strings.
3472 4. Fixed "signed / unsigned compare" compiler warnings.
3473 5. The PIC port manages its own allocation of the general purpose
3474 registers, but makes no attempt to reuse them. As a result when
3475 compiling it soon runs out of general purpose registers. Some
3476 additional code was added to the files pcode.c and device.c to walk
3477 through the function call tree and rename the registers so that they
3487 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3488 genPlus() & genMinus() when the result is the same as left or right

3494 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3496 Made bitfield a distinct type from bit so that bitfields
3497 convert as per ANSI C and bits retain their traditional
3498 boolean style behaviour. Implemented bitfield support in
3506 * src/ds390/gen.c: bit v bitfield split
3507 * src/z80/gen.c: New support for bitfields
3508 * support/regression/tests/bitfields.c: reenabled z80,
3511 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3513 Rules 246.x, 247.x relate to bitfields, the others speed up
3514 access to xdata mapped I/O devices.
3516 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3518 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3520 Cleaned up genPackBits and genUnpackBits and added two helper
3521 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3522 for literal assignments in genPackBits (thanks to Frieder for
3528 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3530 Fixed bug #748310 (pointer to function type mishandled when the
3531 function name is omitted). Also fixed a SIGSEGV when a function
3532 attribute (reentrant, etc) is used on a non-function or on a
3533 function but misplaced before the parameter list.
3535 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3537 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
3538 * support/Util/SDCCerr.h,
3539 * support/Util/SDCCerr.c: Added func attr misuse error msg

3560 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3562 Made the constant following the "interrupt" keyword optional. If
3563 omitted, the function will not automatically be given an entry
3564 in the interrupt vector table (similar to #pragma NOIV, but
3565 less syntacticly kludgy). The interrupt number is also now
3566 range checked. Also fixed a bug in the high order bit example
3573 * support/Util/SDCCerr.c
3574 * support/Util/SDCCerr.h
3577 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

3580 * src/SDCCicode.c (operandOperation): rewritten some ops
3581 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
3582 * src/SDCCsymt.c (computeType): literals are handled the same way as any
3584 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
3585 be re-activated by defining REDUCE_LITERALS)
3586 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
3587 unsigned, but are signed by default
3588 * src/SDCCval.c (constVal): rearranged
3589 * src/SDCCval.c (valMod): preliminary fix
3590 * src/SDCCval.c (valCastLiteral): use TYPE_* types

3632 constants are unsigned; added recognition of "u" flag for unsigned
3633 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
3634 * src/SDCCval.c (valDiv, valMod): fixed signdness
3635 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
3636 signedness of modulo, left and right shift

4042 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4043 the regression tests I'm not brave enough to enable 245.b, 245.c
4044 * doc/sdccman.lyx: added latex preamble for hyperref package.
4045 Using pdflatex this will give you a hyperlinked pdf file with
4046 bookmarks. (prepend '%' before /usepackage if this breaks something)

4084 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
4086 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
4087 it can be defined with CFLAGS when running configure
4088 * src/SDCCmain.c: fixed compiling + linking with object files
4090 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

4093 added --disable-pic16-port
4094 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4095 * src/SDCCmain.c: linkOptions is changed to set *,
4096 added if/endif conditional macros to remove options help
4097 messages from optionsTable when a port is not configured, added
4098 support for the PIc16 port in the ports table, when executing
4099 the compiler with no port specified on command line, a default
4100 port is selected with the new macro DEFAULT_PORT which is
4101 defined in port.h, in setDefaultOptions() linkOptions is removed
4102 from initialization assignment, since now it is a set,
4103 parseCmdLine uses setParseWithComma for linkOptions, in
4104 linkEdit() linkOptions are accessed with new function indexSet()
4105 which returns the i'th item of a set variable. See SDCCset.c, in
4106 linkEdit() when calling buildCmdLine(), added linkOptions as
4107 last argument. Now users can pass arguments to gplink via the
4108 -Wl option, main() uses pic16glue() to glue up pic16 programs
4109 * src/SDCCpeeph.c: various changes to support pic16

4120 * src/pic16/glue.c: commented out some error producing lines
4121 * src/pic16/main.c: __config directives are commented out to stop
4122 gpasm complaining and test the linkage with gplink, _linkCmd and
4123 _asmCmd changed to be more gplink and gpasm friendly
4124 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4125 produced an error when parsed, peep rule 12 is added to utilize
4126 movff, but it is commented out since the pCode does not support
4127 yet a command with 2 address arguments
4129 2003-05-18 <johan AT balder>
4131 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4132 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4158 2003-05-11 Borut Razem <borut.razem AT siol.net>
4160 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4161 the path of bin directory, so that PATH is the only env. variable, which has to be set
4162 in case of standard installation.
4163 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5233 Changes to aslink (All the changes are marked with 'JCF'):
5235 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5238 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5239 area BSEG. Also moves, if possible, the DATA area down into the internal
5240 ram so more space is available.
5242 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5245 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5246 not bytes. Function summary() which creates a memory usage summary
5247 file with extension .mem. Reports of overlaping stack and small stack
5248 size. If the space for the stack is less than 16 bytes aslink trows a
5251 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5252 the 8051. Option 'y' for memory summary output file.
5254 Changes to sdcc (All the changes are marked with 'JCF'):
5256 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5258 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5259 overlaying area for it (uses RegBankUsed[4]).
5261 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5262 bank zero as used by default. By default aslink locates the stack
5263 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5264 the creation of the .mem file. Delegates the allocation of data area
5265 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5266 the begining of the stack area to aslink.
5268 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5269 glue() in SDCCglue.c creates an area for it.
5271 2002-09-03 Borut Razem <borut.razem AT siol.net>
5272 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5273 sdcc/src/pic/glue.c:
5274 introduced atexit() handler for teporay files removal in case of
5275 errors, assertions, ...
5277 2002-08-29 Borut Razem <borut.razem AT siol.net>
5278 * sdcc/support/cpp2/auto-host_vc_in.h:
5279 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5280 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5281 Maybe there is a similar problem with BORLANDC? It should be checked!
5283 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5284 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5285 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5286 was not executed, and the compiler (cl) launched a warning:
5287 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5289 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5290 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5292 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5293 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5295 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5296 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5297 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5298 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5299 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5300 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5301 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5302 - added Release configuration in VS projects
5303 - review of compiler an linker options
5304 - VC .exe files are generated in bin_vc directory, not to interfere
5305 with binaries generated from other projects (cygwin, mingw, bcc ...)
5307 * sdcc/src/yacc.dsp: added
5309 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5310 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5311 and insert the version number definitions from .version
5313 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5315 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5316 added - genarate auto-host.h using auto-host_vc_in.h as template
5319 removed from CVS, generated automatically
5321 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5322 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5324 2002-08-11 Borut Razem <borut.razem AT siol.net>
5325 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5327 2002-08-10 Borut Razem <borut.razem AT siol.net>
5328 * src/SDCCmain.c (main):
5329 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5330 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5331 The consequence was that some temporary files were not removed.
5334 unification of code in functions tempfilename() and tempfile():
5335 function tempnam() is defined in Visual Studio 6.0 and .NET
5337 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5339 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5340 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5341 - removed compiler command line option /WX: Treats all warnings as errors
5342 - update a list of source files, included into the project
5344 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5345 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5346 changed project type to Generic Project so that can be correcly converted to VS.NET project
5348 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5350 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5352 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5354 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5355 added return 0 statements after assert() to make compiler happy
5357 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5358 added newline in the def file to keep MSC compiler satisfied
5360 * sdcc/src/z80/gen.c:
5361 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5362 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5363 - solved MSC error in function aopDump()
5365 * sdcc_vc.h: define PREFIX as "\\sdcc"
5367 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5368 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5411 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5413 Added "char *Processor" field to the port structure.
5416 Added -p option. Allows port dependent processor to be specified.
5419 Initialized the new field char *Processor field to NULL in all ports
5422 Compiler generated registers for interrupt context saving
5423 were not getting allocated.
5425 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5428 Fixed left shift. Will promote the left side of a left shift
5429 if a) left shifting more than size of operand or b) when assigned
5430 to something size > size of left side
5432 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5434 tons of changes. Register allocation has been
5435 rewritten. Added customization for the various PICs. Flow

5540 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
5542 * sdcc/src/SDCCloop.c:
5543 Previous fix was not good. basic blocks that have "break" or "return" are
5544 not really partof a loop , but live ranges used in these blocks should
5545 be live thru the entire loop, so set partOfLoop but don't add them to
5548 2002-02-21 <johan AT FRIJA>
5550 * src/SDCCcse.c: fixed bug #514308
5552 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

5556 statement inside a loop, it was not being considered part of the loop.
5558 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
5560 2002-02-10 Karl Bongers <karl AT turbobit.com>
5563 Fixed up SDCDB debugger somewhat. Updated debugger/README
5564 with lots of comments and notes.
5566 * device/examples/test2.c:
5567 Fix bug, "red" variable not being initialized(compiler complained).
