1827 * src/pic/pcoderegs.c,
1829 * src/pic/ralloc.h: applied patch from Slade Rich;
1830 added support for multiple code pages and multiple RAM banks on the
1831 PIC 14 port. The ASM files now no longer simply assume all the
1832 code / RAM are in the same page / bank. This means the linker can
1833 safely allocate code/RAM of separate ASM files to different pages/banks.
1834 * doc/sdccman.lyx: added Slade's tips
1835 * src/mcs51/peeph.def: fixed bug #880768

1844 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
1847 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
1848 strtof is not part of C89 and isn't included with Mac OS X.
1850 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1852 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,
1853 shiftL2Left2Result): fixed bug #879326
1854 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY

1877 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
1879 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
1880 loaded with the linker search paths (-L arguments) and the libraries
1881 to be linked with the current source (-l arguments). Changes
1882 currently will affect only the pic16 port.
1883 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1884 include path the port specific paths and port specific libraries,
1885 * gplink command now contains the $3 argument,
1886 * src/pic16/device.h,
1887 * src/pic16/device.c,: structure PIC_device is made public and
1888 renamed to PIC16_device, the same for variable Pics which is renamed
1889 to Pics16. Updated all references to them.
1890 * src/pic16/glue.c (pic16glue): corrected bug with code
1891 initialization which bypassed the variable initializations block.
1893 * device/lib/pic16/Makefile.rules: removed --penable-stack from
1894 COMPILE_FLAGS and added the --nostdinc option
1896 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

1901 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
1903 Documenting changes from previous commits.
1904 * configure.in (version 1.56),
1905 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1906 when generating output files to configure the pic16 library,
1907 but now I've commented it out, since gputils aren't installed in the
1908 SF compile farm, so library won't compile
1910 * device/lib/Makefile.in (version 1.56): initially I've added in
1911 target 'all' the prerequestive 'model-pic16' so it compiled the
1912 pic16 library, but now I've commented it out for the same reasons
1914 * added targets 'model-pic16' and 'objects-pic16' to compile the
1916 * added target 'port-specific-objects-pic16' to handle the
1917 generated libraries and copy them into the build/ directory
1918 * added target 'clean-intermediate-pic16' to clean intermediate
1919 files into pic16 directory
1920 * in target 'installdirs' added line to create directory pic16 in
1921 the installation path

1924 added lines to copy all header files to installation path,
1925 * in target 'installdirs' added line create directory for pic16
1926 headers in the installation path

1941 * src/z80/main.c (_parseOptions): fixed the portmode= command line
1942 option so that it actually works. Made it specific to the z80, since
1943 the gbz80 doesn't have these kinds of I/O ports.
1945 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1947 * device/include/z180.h,

1969 Mainly changes to support compilation of the device libraries
1970 * src/pic16/device.c: stack is allocated via symbol and not
1971 via literal number. The symbol is placed in the corresponding
1972 position of the data ram
1973 * (pic16_dump_section): relocatable and absolute uninitialized
1974 data are now emitted in sorted order to reduce section naming,
1975 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
1976 weren't marked as being in the access bank,
1978 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
1980 Added portion of GNU PIC Library under the directory
1981 device/include/pic16 and device/lib/pic16. These files
1982 contain the declarations of SFRs for the PIC18Fxx2 devices.
1983 The directory is initialized via configure from toplevel.
1985 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
1987 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

2013 all over. Telling LaTeX to be less strict with word spacing
2014 to better keep the right margin. Changed some notes about
2015 maintainance of the ports in section 3.2.1 - is it OK like this?

2055 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
2057 * src/pic16/peeph.def: all peepholes with movff are commented out,
2058 because there is a problem in the pcode peep optimizer,
2059 * src/pic16/ralloc.c: the register allocator can now reuse local

2179 * support/valdiag/Makefile,
2180 * support/valdiag/valdiag.py,
2181 * support/valdiag/tests/*

2200 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2202 * sdcc.spec: updated

2211 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2213 PIC16 port related changes:
2214 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2215 added variable stackPos,
2217 * gen.c: genCall, assignResultValue: added support for
2218 pushing/retrieving function parameters to/from stack,
2219 genFunction,genEndFunction: setup stack frame for the
2221 genAddrOf: will be changed according to bug 863624
2223 * added files genutils.c and genutils.h which contain gen*
2224 debugged and optimised functions extracted from gen.c
2226 * glue.c: added variable 'externs' which holds extern symbols,
2227 pic16emitRegularMap: is modified to properly handle relocatable
2228 symbols under the new scheme,
2229 pic16createInterruptVect: is modified
2230 pic16printPublics: is modified to emit 'global' assembler directives,
2231 added pic16_printExterns to print extern symbols,
2232 pic16glue: initializes stack/frame pointer in the beginning of
2233 the assembly output. Temporary hack, will be corrected later,
2234 because gplink yet does not support stack and SDCC does not
2235 yet support a type of crt0.o object to create the final binary.
2237 * Removed many lines that contain 8051 legacy code.
2238 * The code is finally placed under a 'code' directive.
2239 * Added port specific options.
2241 * _process_pragma: simplified since now we do not need *special*
2242 include file to define SFR registers. But a separate header
2243 will be needed. This will be developed later.
2244 * _pic16_parseOptions: added, parses port specific options:
2245 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2246 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2247 --preplace-udata-with=
2249 * _pic16_setDefaultOptions: modified to initialize section names,
2250 but hack is temporarly out of order since it needs improvement.
2251 * _pic16_genAssemblerPreamble: configuration words are emitted by
2252 their address instead of their name. This part is incomplete and
2253 supports only the 18Fxx2 devices. Other devices will emit an error
2254 during assembly since they do not contain the same set of config
2256 * _pic16_genIVT: is modified,
2258 * pcode.c: added definitions for some hardware registers that are needed
2260 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2261 All PCI entries are updated. Now LFSR is supported.
2262 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2263 * added pic16_newpCodeOpLit2 to support instructions with
2264 two literal arguments
2265 * pic16_pCode2str: corrected code that emits assembler instructions
2266 with two literal operands and those that have an access bit modifier
2267 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2268 this fixes a bug which caused some labels to be lost, when an
2269 assembler directive was added, i.e. banksel,
2270 * pic16_FixRegisterBanking: improved logic that causes the insertion
2272 * InlineFunction: functions that are called once, are not any more
2273 inlined. This can be a port option in the future,
2275 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2277 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2278 hold the corresponding uninitialized symbols,
2279 * pic16_allocProcessorRegister: registers have explicit marked the
2281 * pic16_allocInternalRegister: registers are explicit marked as
2283 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2284 processing list, so bit registers were lost,
2287 * ralloc.h: added field 'accessBank' and original symbol operand
2288 in register definition,
2289 * removed the field isMapped from register definition,
2291 ** Several functions have been removed from various sources:
2292 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2293 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2294 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2295 pic16_assignRelocatableRegisters
2297 ** others have been introduced:
2298 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2299 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2301 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2303 * support/scripts/inc2h.pl: changed definition of BIT_AT
2304 to emit 'sbit at' instead of 'bit at'. This was a request.
2306 PIC16 port related preliminary changes:
2307 * gen.c: prefixed function popRegFromString with
2308 pic16_ and all references to it corrected
2309 * pcode.c: all pic16_pc_* hardware registers prefixed
2310 with underscore (_),
2311 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2312 * ralloc.c: newReg(): when register is REG_SFR then
2313 set address to rIdx,
2314 pic16_allocProcessorRegister(): marks register wasUsed=0
2315 pic16_writeUsedRegs(): added a call to assign processor
2316 registers via pic16_assignFixedRegisters
2318 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2320 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2321 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2322 variables in unused register banks. Also the SSEG is placed
2323 wherever there is enough space for it, and IDATA can be anywhere
2324 in internal RAM. For now compile using -Wl-Y[stack_size].
2325 The mem file is different for this option as well, since it
2326 makes no sense of talking about DSEG lenght.
2328 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>

3321 and JUMPTABLE iCodes properly now (worked by accident before)
3322 * src/mcs51/gen.c (leftRightUseAcc),
3323 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
3324 iCode properly now. Use getSize instead of nRegs since a & b
3325 aren't part of the nRegs tally.
3327 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
3329 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()

3335 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
3336 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
3337 fetching of the pointer
3338 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
3339 copied from genNearPointerSet()
3340 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
3341 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
3342 If they pop r0/r1 they must be called in the opposite order than aopOp().
3343 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
3344 (resp. --stack-auto), prepared for --xstack

3355 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
3357 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3358 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
3359 type for bits was changed. It resulted in bit variables becoming
3360 global, which is not permitted in PIC 14 assembly output.
3362 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3364 * doc/sdccman.lyx: various additions and updates. Rearranged sections

3377 A few small changes that speed up the peephole optimizer.
3381 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3383 Try to make the peephole optimizer smarter by maintaining
3384 an association between the assembly source code and the
3385 iCodes that originated them. Put this information to use
3386 with a new peephole rule condition "notVolatile" so that
3387 the rules can be aggressive yet still safe.
3392 * src/mcs51/peeph.def
3394 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3398 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3399 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3400 if the left or right operand symbols have the accuse flag set.
3402 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3404 Changed the type of the result of the ! (NOT) operator to char;
3405 previously it returned the same type as the source. This allows
3406 us to eliminate all the genFloatNot functions (all of its target
3407 implementations were very buggy) since !float can use the same
3410 * src/SDCCicode.c (ast2iCode): ! returns char

3412 * src/ds390/gen.c (genNot, genNotFloat),
3413 * src/z80/gen.c (genNot, genNotFloat),
3414 * src/pic/gen.c (genNot, genNotFloat),

3419 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3420 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3421 during interrupts. Ensure WSAVE is located at a shared bank address.
3422 2. Fixed page selection in some places
3423 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3424 the registers name strings.
3425 4. Fixed "signed / unsigned compare" compiler warnings.
3426 5. The PIC port manages its own allocation of the general purpose
3427 registers, but makes no attempt to reuse them. As a result when
3428 compiling it soon runs out of general purpose registers. Some
3429 additional code was added to the files pcode.c and device.c to walk
3430 through the function call tree and rename the registers so that they
3440 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

3447 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3449 Made bitfield a distinct type from bit so that bitfields
3450 convert as per ANSI C and bits retain their traditional
3451 boolean style behaviour. Implemented bitfield support in
3459 * src/ds390/gen.c: bit v bitfield split
3460 * src/z80/gen.c: New support for bitfields
3461 * support/regression/tests/bitfields.c: reenabled z80,
3464 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3466 Rules 246.x, 247.x relate to bitfields, the others speed up
3467 access to xdata mapped I/O devices.
3469 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3471 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3473 Cleaned up genPackBits and genUnpackBits and added two helper
3474 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
3475 for literal assignments in genPackBits (thanks to Frieder for
3481 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3483 Fixed bug #748310 (pointer to function type mishandled when the
3484 function name is omitted). Also fixed a SIGSEGV when a function
3485 attribute (reentrant, etc) is used on a non-function or on a
3486 function but misplaced before the parameter list.
3488 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
3490 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

3513 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3515 Made the constant following the "interrupt" keyword optional. If
3516 omitted, the function will not automatically be given an entry
3517 in the interrupt vector table (similar to #pragma NOIV, but
3518 less syntacticly kludgy). The interrupt number is also now
3519 range checked. Also fixed a bug in the high order bit example

3540 unsigned, but are signed by default
3541 * src/SDCCval.c (constVal): rearranged
3542 * src/SDCCval.c (valMod): preliminary fix
3543 * src/SDCCval.c (valCastLiteral): use TYPE_* types

3995 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
3996 the regression tests I'm not brave enough to enable 245.b, 245.c
3997 * doc/sdccman.lyx: added latex preamble for hyperref package.
3998 Using pdflatex this will give you a hyperlinked pdf file with
3999 bookmarks. (prepend '%' before /usepackage if this breaks something)

4015 Applied patch from bug 737905 (renamed yylineo to mylineno):
4022 * src/pic16/pcode.c: Cleaned warnings
4023 * src/pic16/pcodeflow.c: Cleaned warnings
4024 * src/pic16/pcoderegs.c: Cleaned warnings

4037 2003-05-18 Bernhard Held <bernhard AT bernhardheld.de>
4039 * src/port.h: removed DEFAULT_PORT, it's not yet pic16 ;-)
4040 it can be defined with CFLAGS when running configure
4041 * src/SDCCmain.c: fixed compiling + linking with object files
4043 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)
4045 * configure.in: configure for pic16 port,
4046 added --disable-pic16-port
4047 * sdccconf_in.h: added macro OPT_DISABLE_PIC16
4048 * src/SDCCmain.c: linkOptions is changed to set *,
4049 added if/endif conditional macros to remove options help
4050 messages from optionsTable when a port is not configured, added
4051 support for the PIc16 port in the ports table, when executing
4052 the compiler with no port specified on command line, a default
4053 port is selected with the new macro DEFAULT_PORT which is
4054 defined in port.h, in setDefaultOptions() linkOptions is removed
4055 from initialization assignment, since now it is a set,
4056 parseCmdLine uses setParseWithComma for linkOptions, in
4057 linkEdit() linkOptions are accessed with new function indexSet()
4058 which returns the i'th item of a set variable. See SDCCset.c, in
4059 linkEdit() when calling buildCmdLine(), added linkOptions as
4060 last argument. Now users can pass arguments to gplink via the
4061 -Wl option, main() uses pic16glue() to glue up pic16 programs
4062 * src/SDCCpeeph.c: various changes to support pic16

4071 * src/pic16/gen.c: bug fix in genCpl(), now the correct code is
4073 * src/pic16/glue.c: commented out some error producing lines
4074 * src/pic16/main.c: __config directives are commented out to stop
4075 gpasm complaining and test the linkage with gplink, _linkCmd and
4076 _asmCmd changed to be more gplink and gpasm friendly
4077 * src/pic16/peeph.def: peep rule 3 is commented out, since it
4078 produced an error when parsed, peep rule 12 is added to utilize
4079 movff, but it is commented out since the pCode does not support
4080 yet a command with 2 address arguments
4082 2003-05-18 <johan AT balder>
4084 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT
4085 * src/ds390/main.c (genArrayInit): removed obsolete and buggy ARRAYINIT

4111 2003-05-11 Borut Razem <borut.razem AT siol.net>
4113 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
4114 the path of bin directory, so that PATH is the only env. variable, which has to be set
4115 in case of standard installation.

5148 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
5149 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
5150 following files to include the previous two files: aslink.dsp,
5151 Makefile.aslink, Makefile.bcc, and Makefile.in.
5153 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5154 .adb instead of .cdb
5156 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5158 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5159 value from option --iram-size.
5161 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5163 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5166 2002-09-18 <wiml AT hhhh.org>
5168 * SDCClrange.h: exposed setFromRange() and setToRange()
5169 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5170 packRegsForAccUse() (bug 542397)
5171 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5172 multiple times and emitting the fetch operations more than once
5173 added aopGetUsesAcc() function to allow binary operators to
5174 fetch their operands in the correct order; made genMinus() emit
5175 compact code for X = LITERAL - Y
5177 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5178 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to

5181 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

5185 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5186 Changes to aslink (All the changes are marked with 'JCF'):
5188 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5191 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5192 area BSEG. Also moves, if possible, the DATA area down into the internal
5193 ram so more space is available.
5195 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5198 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5199 not bytes. Function summary() which creates a memory usage summary
5200 file with extension .mem. Reports of overlaping stack and small stack
5201 size. If the space for the stack is less than 16 bytes aslink trows a
5204 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5205 the 8051. Option 'y' for memory summary output file.
5207 Changes to sdcc (All the changes are marked with 'JCF'):
5209 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5211 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5212 overlaying area for it (uses RegBankUsed[4]).
5214 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5215 bank zero as used by default. By default aslink locates the stack
5216 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5217 the creation of the .mem file. Delegates the allocation of data area
5218 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5219 the begining of the stack area to aslink.
5221 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5222 glue() in SDCCglue.c creates an area for it.
5224 2002-09-03 Borut Razem <borut.razem AT siol.net>
5225 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,

5227 introduced atexit() handler for teporay files removal in case of
5228 errors, assertions, ...
5230 2002-08-29 Borut Razem <borut.razem AT siol.net>
5231 * sdcc/support/cpp2/auto-host_vc_in.h:
5232 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5233 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5234 Maybe there is a similar problem with BORLANDC? It should be checked!
5236 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5237 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5238 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5239 was not executed, and the compiler (cl) launched a warning:
5240 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5242 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5243 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5245 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>

5248 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5249 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5250 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5251 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5252 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5253 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5254 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5255 - added Release configuration in VS projects
5256 - review of compiler an linker options
5257 - VC .exe files are generated in bin_vc directory, not to interfere
5258 with binaries generated from other projects (cygwin, mingw, bcc ...)
5260 * sdcc/src/yacc.dsp: added
5262 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5263 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5264 and insert the version number definitions from .version
5266 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5268 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5269 added - genarate auto-host.h using auto-host_vc_in.h as template
5272 removed from CVS, generated automatically
5274 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>

5277 2002-08-11 Borut Razem <borut.razem AT siol.net>
5278 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5280 2002-08-10 Borut Razem <borut.razem AT siol.net>
5281 * src/SDCCmain.c (main):
5282 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5283 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5284 The consequence was that some temporary files were not removed.
5287 unification of code in functions tempfilename() and tempfile():
5288 function tempnam() is defined in Visual Studio 6.0 and .NET
5290 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5292 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5293 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5294 - removed compiler command line option /WX: Treats all warnings as errors
5295 - update a list of source files, included into the project
5297 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5298 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5299 changed project type to Generic Project so that can be correcly converted to VS.NET project
5301 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5303 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5305 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5307 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5308 added return 0 statements after assert() to make compiler happy
5310 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5311 added newline in the def file to keep MSC compiler satisfied
5313 * sdcc/src/z80/gen.c:
5314 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5315 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5316 - solved MSC error in function aopDump()
5318 * sdcc_vc.h: define PREFIX as "\\sdcc"
5320 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5321 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

5369 Added -p option. Allows port dependent processor to be specified.
5372 Initialized the new field char *Processor field to NULL in all ports
5375 Compiler generated registers for interrupt context saving
5376 were not getting allocated.
5378 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5381 Fixed left shift. Will promote the left side of a left shift
5382 if a) left shifting more than size of operand or b) when assigned
5383 to something size > size of left side
5385 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5387 tons of changes. Register allocation has been
5388 rewritten. Added customization for the various PICs. Flow

5493 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
5495 * sdcc/src/SDCCloop.c:
5496 Previous fix was not good. basic blocks that have "break" or "return" are
5497 not really partof a loop , but live ranges used in these blocks should
5498 be live thru the entire loop, so set partOfLoop but don't add them to
5501 2002-02-21 <johan AT FRIJA>
5503 * src/SDCCcse.c: fixed bug #514308
5505 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>

5509 statement inside a loop, it was not being considered part of the loop.
5511 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
5513 2002-02-10 Karl Bongers <karl AT turbobit.com>
5516 Fixed up SDCDB debugger somewhat. Updated debugger/README
5517 with lots of comments and notes.
5519 * device/examples/test2.c:
5520 Fix bug, "red" variable not being initialized(compiler complained).

5524 for use as a multiple module SDCDB test case.
5526 * sim/ucsim/cmd.src/cmdset.cc:
5527 Took out debug printfs in ucsim "next" command.
5530 Karl and Johan start ucsim XA support. Most dissassembly working,
5531 about 75% emulation done(plenty of work remaining).
5533 * sim/ucsim/z80.src:
5534 Add Z80 support to ucsim, add test-ucz80 regression test,
5535 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
