1818 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
1821 * support/regression/generate-cases.py (main): Changed from inline
1824 * doc/Makefile (install): Changed to depth first to get rid of
1825 missing directory install warning.
1827 * as/Makefile (install-doc): Made work on Mac.
1829 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
1831 * src/SDCCast.c: added an additional type flow in decorateType() of
1832 opposite direction, see feature request #860006; it's enabled at runtime
1833 by setting the environment variable SDCC_NEWTYPEFLOW
1834 * src/SDCCast.h: changed prototype of decorateType()
1835 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
1836 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
1837 'char' to 'int' can be omitted, if both operands are 'unsigned char';
1838 see feature request #877103
1839 * src/SDCCval.c: updated call of decorateType()
1840 (valBitwise): fixed bug #882876
1841 (valMinus): added promotion
1842 (valLogicAndOr): result is unsigned
1843 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
1844 * src/SDCCsymt.c (computeType),
1845 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
1846 must not cause an unsigned operation
1847 * src/pic/glue (pic14emitRegularMap),

1867 * src/pic/ralloc.h: applied patch from Slade Rich;
1868 added support for multiple code pages and multiple RAM banks on the
1869 PIC 14 port. The ASM files now no longer simply assume all the
1870 code / RAM are in the same page / bank. This means the linker can
1871 safely allocate code/RAM of separate ASM files to different pages/banks.
1872 * doc/sdccman.lyx: added Slade's tips
1873 * src/mcs51/peeph.def: fixed bug #880768

1885 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
1886 strtof is not part of C89 and isn't included with Mac OS X.
1888 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1890 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

1915 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
1917 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
1918 loaded with the linker search paths (-L arguments) and the libraries
1919 to be linked with the current source (-l arguments). Changes
1920 currently will affect only the pic16 port.
1921 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1922 include path the port specific paths and port specific libraries,
1923 * gplink command now contains the $3 argument,
1924 * src/pic16/device.h,
1925 * src/pic16/device.c,: structure PIC_device is made public and
1926 renamed to PIC16_device, the same for variable Pics which is renamed

1941 Documenting changes from previous commits.
1942 * configure.in (version 1.56),
1943 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1944 when generating output files to configure the pic16 library,
1945 but now I've commented it out, since gputils aren't installed in the
1946 SF compile farm, so library won't compile
1948 * device/lib/Makefile.in (version 1.56): initially I've added in
1949 target 'all' the prerequestive 'model-pic16' so it compiled the
1950 pic16 library, but now I've commented it out for the same reasons
1952 * added targets 'model-pic16' and 'objects-pic16' to compile the
1954 * added target 'port-specific-objects-pic16' to handle the
1955 generated libraries and copy them into the build/ directory
1956 * added target 'clean-intermediate-pic16' to clean intermediate
1957 files into pic16 directory
1958 * in target 'installdirs' added line to create directory pic16 in
1959 the installation path

1962 added lines to copy all header files to installation path,
1963 * in target 'installdirs' added line create directory for pic16
1964 headers in the installation path

1979 * src/z80/main.c (_parseOptions): fixed the portmode= command line
1980 option so that it actually works. Made it specific to the z80, since
1981 the gbz80 doesn't have these kinds of I/O ports.
1983 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1985 * device/include/z180.h,

2012 data are now emitted in sorted order to reduce section naming,
2013 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2014 weren't marked as being in the access bank,
2016 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2018 Added portion of GNU PIC Library under the directory
2019 device/include/pic16 and device/lib/pic16. These files
2020 contain the declarations of SFRs for the PIC18Fxx2 devices.

2051 all over. Telling LaTeX to be less strict with word spacing
2052 to better keep the right margin. Changed some notes about
2053 maintainance of the ports in section 3.2.1 - is it OK like this?
2055 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2095 * src/pic16/peeph.def: all peepholes with movff are commented out,
2096 because there is a problem in the pcode peep optimizer,
2097 * src/pic16/ralloc.c: the register allocator can now reuse local

2249 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2251 PIC16 port related changes:
2252 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2253 added variable stackPos,
2255 * gen.c: genCall, assignResultValue: added support for
2256 pushing/retrieving function parameters to/from stack,
2257 genFunction,genEndFunction: setup stack frame for the
2259 genAddrOf: will be changed according to bug 863624
2261 * added files genutils.c and genutils.h which contain gen*
2262 debugged and optimised functions extracted from gen.c
2264 * glue.c: added variable 'externs' which holds extern symbols,
2265 pic16emitRegularMap: is modified to properly handle relocatable
2266 symbols under the new scheme,
2267 pic16createInterruptVect: is modified
2268 pic16printPublics: is modified to emit 'global' assembler directives,
2269 added pic16_printExterns to print extern symbols,
2270 pic16glue: initializes stack/frame pointer in the beginning of
2271 the assembly output. Temporary hack, will be corrected later,
2272 because gplink yet does not support stack and SDCC does not
2273 yet support a type of crt0.o object to create the final binary.
2275 * Removed many lines that contain 8051 legacy code.
2276 * The code is finally placed under a 'code' directive.
2277 * Added port specific options.
2279 * _process_pragma: simplified since now we do not need *special*
2280 include file to define SFR registers. But a separate header
2281 will be needed. This will be developed later.
2282 * _pic16_parseOptions: added, parses port specific options:
2283 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2284 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2285 --preplace-udata-with=
2287 * _pic16_setDefaultOptions: modified to initialize section names,
2288 but hack is temporarly out of order since it needs improvement.
2289 * _pic16_genAssemblerPreamble: configuration words are emitted by
2290 their address instead of their name. This part is incomplete and
2291 supports only the 18Fxx2 devices. Other devices will emit an error
2292 during assembly since they do not contain the same set of config
2294 * _pic16_genIVT: is modified,
2296 * pcode.c: added definitions for some hardware registers that are needed
2298 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2299 All PCI entries are updated. Now LFSR is supported.
2300 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2301 * added pic16_newpCodeOpLit2 to support instructions with
2302 two literal arguments
2303 * pic16_pCode2str: corrected code that emits assembler instructions
2304 with two literal operands and those that have an access bit modifier
2305 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2306 this fixes a bug which caused some labels to be lost, when an
2307 assembler directive was added, i.e. banksel,
2308 * pic16_FixRegisterBanking: improved logic that causes the insertion
2310 * InlineFunction: functions that are called once, are not any more
2311 inlined. This can be a port option in the future,
2313 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2315 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2316 hold the corresponding uninitialized symbols,
2317 * pic16_allocProcessorRegister: registers have explicit marked the
2319 * pic16_allocInternalRegister: registers are explicit marked as
2321 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2322 processing list, so bit registers were lost,
2325 * ralloc.h: added field 'accessBank' and original symbol operand
2326 in register definition,
2327 * removed the field isMapped from register definition,
2329 ** Several functions have been removed from various sources:
2330 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2331 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2332 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2333 pic16_assignRelocatableRegisters
2335 ** others have been introduced:
2336 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2337 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2339 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2341 * support/scripts/inc2h.pl: changed definition of BIT_AT
2342 to emit 'sbit at' instead of 'bit at'. This was a request.
2344 PIC16 port related preliminary changes:
2345 * gen.c: prefixed function popRegFromString with
2346 pic16_ and all references to it corrected
2347 * pcode.c: all pic16_pc_* hardware registers prefixed
2348 with underscore (_),
2349 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2350 * ralloc.c: newReg(): when register is REG_SFR then
2351 set address to rIdx,
2352 pic16_allocProcessorRegister(): marks register wasUsed=0
2353 pic16_writeUsedRegs(): added a call to assign processor
2354 registers via pic16_assignFixedRegisters
2356 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2358 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2359 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2360 variables in unused register banks. Also the SSEG is placed
2361 wherever there is enough space for it, and IDATA can be anywhere
2362 in internal RAM. For now compile using -Wl-Y[stack_size].
2363 The mem file is different for this option as well, since it
2364 makes no sense of talking about DSEG lenght.
2366 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2368 * src/SDCClrange.c: fixed bug 869095 that caused segfault

2613 * src/SDCCast.c (decorateType): disabled a transformation I added in
2614 revision 1.188 (access to fields of a structure at an absolute address);
2615 it breaks with bitfields, extern declarations, and gcse analysis.
2616 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
2617 could be assigned through a pointer, so don't complain.

2725 xdata initialization slightly shorter
2727 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3374 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3375 fetching of the pointer
3376 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3377 copied from genNearPointerSet()
3378 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3379 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

3393 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
3395 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3396 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3397 type for bits was changed. It resulted in bit variables becoming
3398 global, which is not permitted in PIC 14 assembly output.
3400 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3402 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3413 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3415 A few small changes that speed up the peephole optimizer.
3419 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3421 Try to make the peephole optimizer smarter by maintaining
3422 an association between the assembly source code and the
3423 iCodes that originated them. Put this information to use
3424 with a new peephole rule condition "notVolatile" so that
3425 the rules can be aggressive yet still safe.
3430 * src/mcs51/peeph.def
3432 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3436 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3437 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3438 if the left or right operand symbols have the accuse flag set.
3440 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3442 Changed the type of the result of the ! (NOT) operator to char;
3443 previously it returned the same type as the source. This allows
3444 us to eliminate all the genFloatNot functions (all of its target
3445 implementations were very buggy) since !float can use the same
3448 * src/SDCCicode.c (ast2iCode): ! returns char
3449 * src/mcs51/gen.c (genNot, genNotFloat),
3450 * src/ds390/gen.c (genNot, genNotFloat),
3451 * src/z80/gen.c (genNot, genNotFloat),
3452 * src/pic/gen.c (genNot, genNotFloat),
3453 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
3455 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
3457 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3458 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3459 during interrupts. Ensure WSAVE is located at a shared bank address.
3460 2. Fixed page selection in some places
3461 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3462 the registers name strings.
3463 4. Fixed "signed / unsigned compare" compiler warnings.
3464 5. The PIC port manages its own allocation of the general purpose
3465 registers, but makes no attempt to reuse them. As a result when
3466 compiling it soon runs out of general purpose registers. Some
3467 additional code was added to the files pcode.c and device.c to walk
3468 through the function call tree and rename the registers so that they
3478 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3479 genPlus() & genMinus() when the result is the same as left or right

3485 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3487 Made bitfield a distinct type from bit so that bitfields
3488 convert as per ANSI C and bits retain their traditional
3489 boolean style behaviour. Implemented bitfield support in
3497 * src/ds390/gen.c: bit v bitfield split
3498 * src/z80/gen.c: New support for bitfields
3499 * support/regression/tests/bitfields.c: reenabled z80,
3502 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3504 Rules 246.x, 247.x relate to bitfields, the others speed up
3505 access to xdata mapped I/O devices.
3507 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3509 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3511 Cleaned up genPackBits and genUnpackBits and added two helper
3512 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3513 for literal assignments in genPackBits (thanks to Frieder for
3519 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3521 Fixed bug #748310 (pointer to function type mishandled when the
3522 function name is omitted). Also fixed a SIGSEGV when a function
3523 attribute (reentrant, etc) is used on a non-function or on a
3524 function but misplaced before the parameter list.
3526 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3528 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

3551 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3553 Made the constant following the "interrupt" keyword optional. If
3554 omitted, the function will not automatically be given an entry
3555 in the interrupt vector table (similar to #pragma NOIV, but
3556 less syntacticly kludgy). The interrupt number is also now
3557 range checked. Also fixed a bug in the high order bit example
3564 * support/Util/SDCCerr.c
3565 * support/Util/SDCCerr.h
3568 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>

3571 * src/SDCCicode.c (operandOperation): rewritten some ops
3572 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
3573 * src/SDCCsymt.c (computeType): literals are handled the same way as any
3575 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
3576 be re-activated by defining REDUCE_LITERALS)
3577 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
3578 unsigned, but are signed by default
3579 * src/SDCCval.c (constVal): rearranged
3580 * src/SDCCval.c (valMod): preliminary fix
3581 * src/SDCCval.c (valCastLiteral): use TYPE_* types

4033 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
4034 the regression tests I'm not brave enough to enable 245.b, 245.c
4035 * doc/sdccman.lyx: added latex preamble for hyperref package.
4036 Using pdflatex this will give you a hyperlinked pdf file with
4037 bookmarks. (prepend '%' before /usepackage if this breaks something)

4075 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
4077 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
4078 it can be defined with CFLAGS when running configure
4079 * src/SDCCmain.c: fixed compiling + linking with object files
4081 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

4084 added --disable-pic16-port
4085 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4086 * src/SDCCmain.c: linkOptions is changed to set *,
4087 added if/endif conditional macros to remove options help
4088 messages from optionsTable when a port is not configured, added
4089 support for the PIc16 port in the ports table, when executing
4090 the compiler with no port specified on command line, a default
4091 port is selected with the new macro DEFAULT_PORT which is
4092 defined in port.h, in setDefaultOptions() linkOptions is removed
4093 from initialization assignment, since now it is a set,
4094 parseCmdLine uses setParseWithComma for linkOptions, in
4095 linkEdit() linkOptions are accessed with new function indexSet()
4096 which returns the i'th item of a set variable. See SDCCset.c, in
4097 linkEdit() when calling buildCmdLine(), added linkOptions as
4098 last argument. Now users can pass arguments to gplink via the
4099 -Wl option, main() uses pic16glue() to glue up pic16 programs

4111 * src/pic16/glue.c: commented out some error producing lines
4112 * src/pic16/main.c: __config directives are commented out to stop
4113 gpasm complaining and test the linkage with gplink, _linkCmd and
4114 _asmCmd changed to be more gplink and gpasm friendly
4115 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4116 produced an error when parsed, peep rule 12 is added to utilize
4117 movff, but it is commented out since the pCode does not support
4118 yet a command with 2 address arguments
4120 2003-05-18 <johan AT balder>
4122 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4149 2003-05-11 Borut Razem <borut.razem AT siol.net>
4151 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4152 the path of bin directory, so that PATH is the only env. variable, which has to be set
4153 in case of standard installation.
4154 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5236 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5237 not bytes. Function summary() which creates a memory usage summary
5238 file with extension .mem. Reports of overlaping stack and small stack
5239 size. If the space for the stack is less than 16 bytes aslink trows a
5242 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5243 the 8051. Option 'y' for memory summary output file.
5245 Changes to sdcc (All the changes are marked with 'JCF'):
5247 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5249 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5250 overlaying area for it (uses RegBankUsed[4]).
5252 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5253 bank zero as used by default. By default aslink locates the stack
5254 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5255 the creation of the .mem file. Delegates the allocation of data area
5256 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5257 the begining of the stack area to aslink.
5259 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5260 glue() in SDCCglue.c creates an area for it.
5262 2002-09-03 Borut Razem <borut.razem AT siol.net>
5263 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5264 sdcc/src/pic/glue.c:
5265 introduced atexit() handler for teporay files removal in case of
5266 errors, assertions, ...
5268 2002-08-29 Borut Razem <borut.razem AT siol.net>
5269 * sdcc/support/cpp2/auto-host_vc_in.h:
5270 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5271 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5272 Maybe there is a similar problem with BORLANDC? It should be checked!
5274 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5275 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5276 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5277 was not executed, and the compiler (cl) launched a warning:
5278 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5280 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5281 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5283 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5284 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5286 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5287 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5288 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5289 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5290 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5291 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5292 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5293 - added Release configuration in VS projects
5294 - review of compiler an linker options
5295 - VC .exe files are generated in bin_vc directory, not to interfere
5296 with binaries generated from other projects (cygwin, mingw, bcc ...)
5298 * sdcc/src/yacc.dsp: added
5300 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5301 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5302 and insert the version number definitions from .version
5304 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5306 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5307 added - genarate auto-host.h using auto-host_vc_in.h as template
5310 removed from CVS, generated automatically
5312 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5313 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5315 2002-08-11 Borut Razem <borut.razem AT siol.net>
5316 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5318 2002-08-10 Borut Razem <borut.razem AT siol.net>
5319 * src/SDCCmain.c (main):
5320 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5321 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5322 The consequence was that some temporary files were not removed.
5325 unification of code in functions tempfilename() and tempfile():
5326 function tempnam() is defined in Visual Studio 6.0 and .NET
5328 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5330 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5331 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5332 - removed compiler command line option /WX: Treats all warnings as errors
5333 - update a list of source files, included into the project
5335 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5336 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5337 changed project type to Generic Project so that can be correcly converted to VS.NET project
5339 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5341 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5343 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5345 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5346 added return 0 statements after assert() to make compiler happy
5348 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5349 added newline in the def file to keep MSC compiler satisfied
5351 * sdcc/src/z80/gen.c:
5352 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5353 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5354 - solved MSC error in function aopDump()
5356 * sdcc_vc.h: define PREFIX as "\\sdcc"
5358 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5359 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5407 Added -p option. Allows port dependent processor to be specified.
5410 Initialized the new field char *Processor field to NULL in all ports
5413 Compiler generated registers for interrupt context saving
5414 were not getting allocated.
5416 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5419 Fixed left shift. Will promote the left side of a left shift
5420 if a) left shifting more than size of operand or b) when assigned
5421 to something size > size of left side
5423 2002-03-14 Scott Dattalo <scott AT dattalo.com>

5531 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
5533 * sdcc/src/SDCCloop.c:
5534 Previous fix was not good. basic blocks that have "break" or "return" are
5535 not really partof a loop , but live ranges used in these blocks should
5536 be live thru the entire loop, so set partOfLoop but don't add them to
5539 2002-02-21 <johan AT FRIJA>
5541 * src/SDCCcse.c: fixed bug #514308
5543 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

5547 statement inside a loop, it was not being considered part of the loop.
5549 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
5551 2002-02-10 Karl Bongers <karl AT turbobit.com>
