1820 2004-01-27 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1822 * ChangeLog: changed "@" to " AT " in hopes of reducing spam and
1823 virus/worm forged address usage.
1825 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
1827 Fixed promotion, it should be done on AST level:
1828 * src/SDCCast.c (addCast): added promotion to int
1829 (decorateType): updated call to upCast()
1830 * src/SDCCicode.c (geniCodeLeftShift): removed call to
1831 usualUnaryConversions()
1833 2004-01-26 Michael Hope <michaelh AT juju.net.nz>
1835 * support/regression/tests/literalop.c (mulWrapper): Added a
1836 wrapper to remove integer overflow warnings.
1838 * support/regression/tests/float_trans.c: Made work on host.
1840 * support/regression/ports/ucz80/spec.mk (UCZ80): Made detect the
1843 * support/regression/generate-cases.py (main): Changed from inline
1846 * doc/Makefile (install): Changed to depth first to get rid of
1847 missing directory install warning.
1849 * as/Makefile (install-doc): Made work on Mac.
1851 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
1853 * src/SDCCast.c: added an additional type flow in decorateType() of
1854 opposite direction, see feature request #860006; it's enabled at runtime
1855 by setting the environment variable SDCC_NEWTYPEFLOW
1856 * src/SDCCast.h: changed prototype of decorateType()
1857 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
1858 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
1859 'char' to 'int' can be omitted, if both operands are 'unsigned char';
1860 see feature request #877103
1861 * src/SDCCval.c: updated call of decorateType()
1862 (valBitwise): fixed bug #882876
1863 (valMinus): added promotion
1864 (valLogicAndOr): result is unsigned
1865 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
1866 * src/SDCCsymt.c (computeType),
1867 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'
1868 must not cause an unsigned operation

1889 * src/pic/ralloc.h: applied patch from Slade Rich;
1890 added support for multiple code pages and multiple RAM banks on the
1891 PIC 14 port. The ASM files now no longer simply assume all the
1892 code / RAM are in the same page / bank. This means the linker can
1893 safely allocate code/RAM of separate ASM files to different pages/banks.
1894 * doc/sdccman.lyx: added Slade's tips
1895 * src/mcs51/peeph.def: fixed bug #880768

1907 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
1908 strtof is not part of C89 and isn't included with Mac OS X.
1910 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1912 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

1937 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
1939 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
1940 loaded with the linker search paths (-L arguments) and the libraries
1941 to be linked with the current source (-l arguments). Changes
1942 currently will affect only the pic16 port.
1943 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1944 include path the port specific paths and port specific libraries,
1945 * gplink command now contains the $3 argument,
1946 * src/pic16/device.h,
1947 * src/pic16/device.c,: structure PIC_device is made public and
1948 renamed to PIC16_device, the same for variable Pics which is renamed

1963 Documenting changes from previous commits.
1964 * configure.in (version 1.56),
1965 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1966 when generating output files to configure the pic16 library,
1967 but now I've commented it out, since gputils aren't installed in the
1968 SF compile farm, so library won't compile
1970 * device/lib/Makefile.in (version 1.56): initially I've added in
1971 target 'all' the prerequestive 'model-pic16' so it compiled the
1972 pic16 library, but now I've commented it out for the same reasons
1974 * added targets 'model-pic16' and 'objects-pic16' to compile the
1976 * added target 'port-specific-objects-pic16' to handle the
1977 generated libraries and copy them into the build/ directory
1978 * added target 'clean-intermediate-pic16' to clean intermediate
1979 files into pic16 directory
1980 * in target 'installdirs' added line to create directory pic16 in
1981 the installation path
1983 * device/include/Makefile.in (version 1.11): in target 'install'
1984 added lines to copy all header files to installation path,
1985 * in target 'installdirs' added line create directory for pic16
1986 headers in the installation path

2001 * src/z80/main.c (_parseOptions): fixed the portmode= command line
2002 option so that it actually works. Made it specific to the z80, since
2003 the gbz80 doesn't have these kinds of I/O ports.
2005 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2007 * device/include/z180.h,

2029 Mainly changes to support compilation of the device libraries
2030 * src/pic16/device.c: stack is allocated via symbol and not
2031 via literal number. The symbol is placed in the corresponding
2032 position of the data ram
2033 * (pic16_dump_section): relocatable and absolute uninitialized
2034 data are now emitted in sorted order to reduce section naming,
2035 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
2036 weren't marked as being in the access bank,
2038 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
2040 Added portion of GNU PIC Library under the directory
2041 device/include/pic16 and device/lib/pic16. These files
2042 contain the declarations of SFRs for the PIC18Fxx2 devices.
2043 The directory is initialized via configure from toplevel.

2073 all over. Telling LaTeX to be less strict with word spacing
2074 to better keep the right margin. Changed some notes about
2075 maintainance of the ports in section 3.2.1 - is it OK like this?
2077 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2117 * src/pic16/peeph.def: all peepholes with movff are commented out,
2118 because there is a problem in the pcode peep optimizer,
2119 * src/pic16/ralloc.c: the register allocator can now reuse local

2258 Bug reported from Jesus Calvino-Fraga
2260 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2262 * sdcc.spec: updated
2263 * device/include/Makefile.in: don't install CVS directories
2264 * device/lib/Makefile.in: added removal of CVS directories after install
2265 * doc/Makefile: fixed install, added local_icons
2266 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2267 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2268 * src/ds390/gen.c (genRightShift): fixed bug #870788
2269 * src/SDCCast.c (decorateType): fixed bug #870781
2271 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2273 PIC16 port related changes:
2274 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2275 added variable stackPos,
2277 * gen.c: genCall, assignResultValue: added support for
2278 pushing/retrieving function parameters to/from stack,
2279 genFunction,genEndFunction: setup stack frame for the
2281 genAddrOf: will be changed according to bug 863624
2283 * added files genutils.c and genutils.h which contain gen*
2284 debugged and optimised functions extracted from gen.c
2286 * glue.c: added variable 'externs' which holds extern symbols,
2287 pic16emitRegularMap: is modified to properly handle relocatable
2288 symbols under the new scheme,
2289 pic16createInterruptVect: is modified
2290 pic16printPublics: is modified to emit 'global' assembler directives,
2291 added pic16_printExterns to print extern symbols,
2292 pic16glue: initializes stack/frame pointer in the beginning of
2293 the assembly output. Temporary hack, will be corrected later,
2294 because gplink yet does not support stack and SDCC does not
2295 yet support a type of crt0.o object to create the final binary.
2297 * Removed many lines that contain 8051 legacy code.
2298 * The code is finally placed under a 'code' directive.
2299 * Added port specific options.
2301 * _process_pragma: simplified since now we do not need *special*
2302 include file to define SFR registers. But a separate header
2303 will be needed. This will be developed later.
2304 * _pic16_parseOptions: added, parses port specific options:
2305 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2306 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2307 --preplace-udata-with=
2309 * _pic16_setDefaultOptions: modified to initialize section names,
2310 but hack is temporarly out of order since it needs improvement.
2311 * _pic16_genAssemblerPreamble: configuration words are emitted by
2312 their address instead of their name. This part is incomplete and
2313 supports only the 18Fxx2 devices. Other devices will emit an error
2314 during assembly since they do not contain the same set of config
2316 * _pic16_genIVT: is modified,
2318 * pcode.c: added definitions for some hardware registers that are needed
2320 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2321 All PCI entries are updated. Now LFSR is supported.
2322 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2323 * added pic16_newpCodeOpLit2 to support instructions with
2324 two literal arguments
2325 * pic16_pCode2str: corrected code that emits assembler instructions
2326 with two literal operands and those that have an access bit modifier
2327 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2328 this fixes a bug which caused some labels to be lost, when an
2329 assembler directive was added, i.e. banksel,
2330 * pic16_FixRegisterBanking: improved logic that causes the insertion
2332 * InlineFunction: functions that are called once, are not any more
2333 inlined. This can be a port option in the future,
2335 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2337 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2338 hold the corresponding uninitialized symbols,
2339 * pic16_allocProcessorRegister: registers have explicit marked the
2341 * pic16_allocInternalRegister: registers are explicit marked as
2343 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2344 processing list, so bit registers were lost,
2347 * ralloc.h: added field 'accessBank' and original symbol operand
2348 in register definition,
2349 * removed the field isMapped from register definition,
2351 ** Several functions have been removed from various sources:
2352 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2353 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2354 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2355 pic16_assignRelocatableRegisters
2357 ** others have been introduced:
2358 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2359 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2361 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2363 * support/scripts/inc2h.pl: changed definition of BIT_AT
2364 to emit 'sbit at' instead of 'bit at'. This was a request.
2366 PIC16 port related preliminary changes:
2367 * gen.c: prefixed function popRegFromString with
2368 pic16_ and all references to it corrected
2369 * pcode.c: all pic16_pc_* hardware registers prefixed
2370 with underscore (_),
2371 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2372 * ralloc.c: newReg(): when register is REG_SFR then
2373 set address to rIdx,
2374 pic16_allocProcessorRegister(): marks register wasUsed=0
2375 pic16_writeUsedRegs(): added a call to assign processor
2376 registers via pic16_assignFixedRegisters
2378 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2380 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2381 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2382 variables in unused register banks. Also the SSEG is placed
2383 wherever there is enough space for it, and IDATA can be anywhere
2384 in internal RAM. For now compile using -Wl-Y[stack_size].
2385 The mem file is different for this option as well, since it
2386 makes no sense of talking about DSEG lenght.
2388 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2390 * src/SDCClrange.c: fixed bug 869095 that caused segfault

2635 * src/SDCCast.c (decorateType): disabled a transformation I added in
2636 revision 1.188 (access to fields of a structure at an absolute address);
2637 it breaks with bitfields, extern declarations, and gcse analysis.
2638 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
2639 could be assigned through a pointer, so don't complain.

2747 xdata initialization slightly shorter
2749 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

3396 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3397 fetching of the pointer
3398 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3399 copied from genNearPointerSet()
3400 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3401 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

3417 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3418 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3419 type for bits was changed. It resulted in bit variables becoming
3420 global, which is not permitted in PIC 14 assembly output.
3422 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3424 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3437 A few small changes that speed up the peephole optimizer.
3441 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3443 Try to make the peephole optimizer smarter by maintaining
3444 an association between the assembly source code and the
3445 iCodes that originated them. Put this information to use
3446 with a new peephole rule condition "notVolatile" so that
3447 the rules can be aggressive yet still safe.
3452 * src/mcs51/peeph.def
3454 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3458 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3459 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3460 if the left or right operand symbols have the accuse flag set.
3462 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3464 Changed the type of the result of the ! (NOT) operator to char;
3465 previously it returned the same type as the source. This allows
3466 us to eliminate all the genFloatNot functions (all of its target
3467 implementations were very buggy) since !float can use the same

3479 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3480 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3481 during interrupts. Ensure WSAVE is located at a shared bank address.
3482 2. Fixed page selection in some places
3483 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3484 the registers name strings.
3485 4. Fixed "signed / unsigned compare" compiler warnings.
3486 5. The PIC port manages its own allocation of the general purpose
3487 registers, but makes no attempt to reuse them. As a result when
3488 compiling it soon runs out of general purpose registers. Some
3489 additional code was added to the files pcode.c and device.c to walk
3490 through the function call tree and rename the registers so that they
3500 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
3501 genPlus() & genMinus() when the result is the same as left or right

3507 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3509 Made bitfield a distinct type from bit so that bitfields
3510 convert as per ANSI C and bits retain their traditional
3511 boolean style behaviour. Implemented bitfield support in
3519 * src/ds390/gen.c: bit v bitfield split
3520 * src/z80/gen.c: New support for bitfields
3521 * support/regression/tests/bitfields.c: reenabled z80,
3524 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3526 Rules 246.x, 247.x relate to bitfields, the others speed up
3527 access to xdata mapped I/O devices.
3529 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3531 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3533 Cleaned up genPackBits and genUnpackBits and added two helper
3534 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3535 for literal assignments in genPackBits (thanks to Frieder for
3541 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3543 Fixed bug #748310 (pointer to function type mishandled when the
3544 function name is omitted). Also fixed a SIGSEGV when a function
3545 attribute (reentrant, etc) is used on a non-function or on a
3546 function but misplaced before the parameter list.
3548 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3550 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
3551 * support/Util/SDCCerr.h,
3552 * support/Util/SDCCerr.c: Added func attr misuse error msg

3573 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3575 Made the constant following the "interrupt" keyword optional. If
3576 omitted, the function will not automatically be given an entry
3577 in the interrupt vector table (similar to #pragma NOIV, but
3578 less syntacticly kludgy). The interrupt number is also now
3579 range checked. Also fixed a bug in the high order bit example

3593 * src/SDCCicode.c (operandOperation): rewritten some ops
3594 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
3595 * src/SDCCsymt.c (computeType): literals are handled the same way as any
3597 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
3598 be re-activated by defining REDUCE_LITERALS)
3599 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
3600 unsigned, but are signed by default
3601 * src/SDCCval.c (constVal): rearranged
3602 * src/SDCCval.c (valMod): preliminary fix
3603 * src/SDCCval.c (valCastLiteral): use TYPE_* types

3645 constants are unsigned; added recognition of "u" flag for unsigned
3646 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
3647 * src/SDCCval.c (valDiv, valMod): fixed signdness
3648 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
3649 signedness of modulo, left and right shift

4106 added --disable-pic16-port
4107 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4108 * src/SDCCmain.c: linkOptions is changed to set *,
4109 added if/endif conditional macros to remove options help
4110 messages from optionsTable when a port is not configured, added
4111 support for the PIc16 port in the ports table, when executing
4112 the compiler with no port specified on command line, a default
4113 port is selected with the new macro DEFAULT_PORT which is
4114 defined in port.h, in setDefaultOptions() linkOptions is removed
4115 from initialization assignment, since now it is a set,
4116 parseCmdLine uses setParseWithComma for linkOptions, in
4117 linkEdit() linkOptions are accessed with new function indexSet()
4118 which returns the i'th item of a set variable. See SDCCset.c, in
4119 linkEdit() when calling buildCmdLine(), added linkOptions as
4120 last argument. Now users can pass arguments to gplink via the
4121 -Wl option, main() uses pic16glue() to glue up pic16 programs

4133 * src/pic16/glue.c: commented out some error producing lines
4134 * src/pic16/main.c: __config directives are commented out to stop
4135 gpasm complaining and test the linkage with gplink, _linkCmd and
4136 _asmCmd changed to be more gplink and gpasm friendly
4137 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4138 produced an error when parsed, peep rule 12 is added to utilize
4139 movff, but it is commented out since the pCode does not support
4140 yet a command with 2 address arguments
4142 2003-05-18 <johan AT balder>
4144 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4171 2003-05-11 Borut Razem <borut.razem AT siol.net>
4173 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4174 the path of bin directory, so that PATH is the only env. variable, which has to be set
4175 in case of standard installation.
4176 * src/ds390/ds390.dsp: increased value of /Zm option to 1000

5233 added aopGetUsesAcc() function to allow binary operators to
5234 fetch their operands in the correct order; made genMinus() emit
5235 compact code for X = LITERAL - Y
5237 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5238 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5239 sprintf() in line 1267.
5241 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5242 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5245 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5246 Changes to aslink (All the changes are marked with 'JCF'):
5248 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5251 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5252 area BSEG. Also moves, if possible, the DATA area down into the internal
5253 ram so more space is available.
5255 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5258 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5259 not bytes. Function summary() which creates a memory usage summary
5260 file with extension .mem. Reports of overlaping stack and small stack
5261 size. If the space for the stack is less than 16 bytes aslink trows a
5264 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5265 the 8051. Option 'y' for memory summary output file.
5267 Changes to sdcc (All the changes are marked with 'JCF'):
5269 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5271 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5272 overlaying area for it (uses RegBankUsed[4]).
5274 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5275 bank zero as used by default. By default aslink locates the stack
5276 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5277 the creation of the .mem file. Delegates the allocation of data area
5278 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5279 the begining of the stack area to aslink.
5281 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5282 glue() in SDCCglue.c creates an area for it.
5284 2002-09-03 Borut Razem <borut.razem AT siol.net>
5285 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5286 sdcc/src/pic/glue.c:
5287 introduced atexit() handler for teporay files removal in case of
5288 errors, assertions, ...
5290 2002-08-29 Borut Razem <borut.razem AT siol.net>
5291 * sdcc/support/cpp2/auto-host_vc_in.h:
5292 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5293 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5294 Maybe there is a similar problem with BORLANDC? It should be checked!
5296 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5297 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5298 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5299 was not executed, and the compiler (cl) launched a warning:
5300 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5302 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5303 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5305 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5306 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5308 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5309 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5310 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5311 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5312 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5313 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5314 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5315 - added Release configuration in VS projects
5316 - review of compiler an linker options
5317 - VC .exe files are generated in bin_vc directory, not to interfere
5318 with binaries generated from other projects (cygwin, mingw, bcc ...)
5320 * sdcc/src/yacc.dsp: added
5322 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5323 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5324 and insert the version number definitions from .version
5326 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5328 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5329 added - genarate auto-host.h using auto-host_vc_in.h as template
5332 removed from CVS, generated automatically
5334 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5335 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5337 2002-08-11 Borut Razem <borut.razem AT siol.net>
5338 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5340 2002-08-10 Borut Razem <borut.razem AT siol.net>
5341 * src/SDCCmain.c (main):
5342 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5343 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5344 The consequence was that some temporary files were not removed.
5347 unification of code in functions tempfilename() and tempfile():
5348 function tempnam() is defined in Visual Studio 6.0 and .NET
5350 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5352 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5353 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5354 - removed compiler command line option /WX: Treats all warnings as errors
5355 - update a list of source files, included into the project
5357 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5358 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5359 changed project type to Generic Project so that can be correcly converted to VS.NET project
5361 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5363 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5365 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5367 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5368 added return 0 statements after assert() to make compiler happy
5370 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5371 added newline in the def file to keep MSC compiler satisfied
5373 * sdcc/src/z80/gen.c:
5374 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5375 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5376 - solved MSC error in function aopDump()
5378 * sdcc_vc.h: define PREFIX as "\\sdcc"
5380 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5381 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5420 2002-03-28 Johan Knol <johan AT balder>
5422 * src/SDCCval.c: fixed bug #532436
5424 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5426 Added "char *Processor" field to the port structure.
5429 Added -p option. Allows port dependent processor to be specified.
5432 Initialized the new field char *Processor field to NULL in all ports
5435 Compiler generated registers for interrupt context saving
5436 were not getting allocated.
5438 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5441 Fixed left shift. Will promote the left side of a left shift
5442 if a) left shifting more than size of operand or b) when assigned
5443 to something size > size of left side
5445 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5447 tons of changes. Register allocation has been
5448 rewritten. Added customization for the various PICs. Flow

5553 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
5555 * sdcc/src/SDCCloop.c:
5556 Previous fix was not good. basic blocks that have "break" or "return" are
5557 not really partof a loop , but live ranges used in these blocks should
5558 be live thru the entire loop, so set partOfLoop but don't add them to
5561 2002-02-21 <johan AT FRIJA>
5563 * src/SDCCcse.c: fixed bug #514308
5565 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
5568 Fixed BUG #519583. If a conditional block ended in a return/break
5569 statement inside a loop, it was not being considered part of the loop.
5571 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
5573 2002-02-10 Karl Bongers <karl AT turbobit.com>
5576 Fixed up SDCDB debugger somewhat. Updated debugger/README
5577 with lots of comments and notes.
5579 * device/examples/test2.c:
5580 Fix bug, "red" variable not being initialized(compiler complained).
