2174 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2176 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
2179 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2181 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
2182 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
2184 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
2186 * device/lib/printf_large.c: removed inline assembly for portability and
2187 readability. Use printf_fast if speed or size are more important.
2188 * src/pic16/gen.c: removed conditions around use of DEBUGpc
2189 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
2191 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
2193 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
2194 prevent compiler warning
2196 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2198 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
2199 moved to level 0 and declared as static. Also they are explicit
2200 placed in access bank. This was necessery because some times they
2201 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
2202 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
2203 optimizations. Currently only compare to unsigned char is implemented,
2204 * src/pic16/gen.c: added fReturnIdx array,
2205 * (struct resolvedIfx) is moved to gen.h and made public,
2206 * (struct _G): added sregsAlloc and sregsAllocSet fields,
2207 * (aopForSym): added an optimization to directly store in stack of
2208 the operand of a SEND iCode,
2209 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
2210 but as registers instead (AOP_REG) using the fReturnIdx array,
2211 * (pic16_freeAsmop): remove the freed register from the
2212 _G.sregsAlloc field,
2213 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
2214 a compare of 'WREG',
2215 * (pic16_popGetTempRegCond): changed function prototype, now
2216 function takes also a bitVector argument v which holds the current
2217 set of registers that are allocated for stack access by aopForSym,
2218 registers allocated in aopForSym for accessing stack symbols are not
2219 any more part of the functions usedRegs field,
2220 * (genCall): some times aopOp is called for a stack variable to be
2221 send, aopForSym might perform the push, if this is true make sure
2222 that genCall doesn't push the variable twice by testing _G.resDirect,
2223 * (genFunction): changed testing for unspecified interrupt number
2224 from 256 to INTNO_UNSPEC,
2225 * modified selection scheme of frame pointer generation. Previously
2226 if function did use local registers a frame pointer was generated,
2227 now a frame pointer is generated only if function has arguments
2228 (that need PLUSW2 register access), or has stack arguments, or the
2229 compiler is not instructed to omit the frame pointer,
2230 * (genEndFunction): before restoring local registers that were saved
2231 in the function preamble, also restore the registers that *might*
2232 have been allocated for stack access,
2233 * (genRet): removed some old comments,
2234 * (genCmp, the active (RN's) version): added a call to the
2235 pic16_genCmp_special function to perform the compare with a more
2236 robust and optimized way,
2237 * (genInline): a feature has been added in inline code generation,
2238 which allows a wildcard variable substitution when writing inline
2239 assembly. Code is incomplete and experimental therefore undocumented,
2240 * (genCast): changed order of aopOp for result and right to allow
2241 aopForSym to directly load the result if possible,
2242 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
2243 perform an optimized compare on some selected special occasions,
2244 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
2245 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
2246 generate an IVT any more,
2247 * src/pic16/main.c (pic16_optionsTable): added command line option
2249 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
2250 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
2252 * src/pic16/NOTES: Raphael Neider added in list of active developers
2253 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
2254 jumptable_end to prevent bug #,
2255 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
2256 inCond and outCond fields,
2257 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
2258 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
2259 turn off register spilling,
2260 * (packRegsForOneUse): synced with other ports' versions although it
2261 is not used currently,
2262 * (pic16_packRegisters): added an optimization while reading
2263 structure bitfields, some registers may be saved (malloc code is
2264 decreased by 80 bytes)
2266 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
2268 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
2269 left is a bitfield, if yes, then don't optimize assignment. Perhaps
2270 this can be optimized more?
2272 2005-03-10 Raphael Neider <rneider AT web.de>
2274 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
2275 genNearPointerGet): (hopefully) fixed access to bitfields via
2276 pointers (p->bitN = x; and x = p->bitN; failed)
2278 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
2280 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

2321 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
2322 to keep the correct label reference count when adding/removing references
2323 to labels. A peephole file using this is appended to patch #1144962.

2602 access stack and frame pointers. They are initially assigned to
2603 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
2604 accessing SFRs. Updated all occurences of modification of stack or
2605 frame pointer in gen.c and pcode.c,
2606 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with

2911 generated for switch statements. For now you need to set the
2912 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2913 Now 4 algorithms for mcs51 jumptable generation are used:
2914 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

2949 functions, ctype functions and macros and some functions of the
2950 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2951 be extensively tested in the future. Standard disclaimer here.

2966 special compare&skip instructions. Initial tests fail some times
2967 with variables grater than 1 byte in size, so new code is disabled,
2968 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2970 * (genCast): began a fix to optimize the casting of a bit to another
2971 bit, now assigning a bitfield to another bitfield will fail, sorry,

2986 * src/pic16/ralloc.c (allocReg): add preliminary support for
2987 supporting a limited set of temporary registers,

5996 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5997 loaded with the linker search paths (-L arguments) and the libraries
5998 to be linked with the current source (-l arguments). Changes
5999 currently will affect only the pic16 port.
6000 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
6001 include path the port specific paths and port specific libraries,
6002 * gplink command now contains the $3 argument,
6003 * src/pic16/device.h,
6004 * src/pic16/device.c,: structure PIC_device is made public and
6005 renamed to PIC16_device, the same for variable Pics which is renamed

6020 Documenting changes from previous commits.
6021 * configure.in (version 1.56),
6022 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
6023 when generating output files to configure the pic16 library,
6024 but now I've commented it out, since gputils aren't installed in the
6025 SF compile farm, so library won't compile
6027 * device/lib/Makefile.in (version 1.56): initially I've added in
6028 target 'all' the prerequestive 'model-pic16' so it compiled the
6029 pic16 library, but now I've commented it out for the same reasons
6031 * added targets 'model-pic16' and 'objects-pic16' to compile the
6033 * added target 'port-specific-objects-pic16' to handle the
6034 generated libraries and copy them into the build/ directory
6035 * added target 'clean-intermediate-pic16' to clean intermediate
6036 files into pic16 directory
6037 * in target 'installdirs' added line to create directory pic16 in
6038 the installation path

6041 added lines to copy all header files to installation path,
6042 * in target 'installdirs' added line create directory for pic16
6043 headers in the installation path

6059 option so that it actually works. Made it specific to the z80, since
6060 the gbz80 doesn't have these kinds of I/O ports.
6062 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6064 * device/include/z180.h,

6088 via literal number. The symbol is placed in the corresponding
6089 position of the data ram
6090 * (pic16_dump_section): relocatable and absolute uninitialized
6091 data are now emitted in sorted order to reduce section naming,
6092 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
6093 weren't marked as being in the access bank,

6171 UPPER for immediate operands,
6172 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
6174 * src/pic16/peeph.def: all peepholes with movff are commented out,
6175 because there is a problem in the pcode peep optimizer,
6176 * src/pic16/ralloc.c: the register allocator can now reuse local
6177 function symbols for another function. This saves register usage.
6178 * src/pic16/ralloc.h: added flag isLocal in structure regs,
6180 Added file src/pic16/NOTES with information about program writing on

6286 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6288 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
6289 (default behaviour).
6291 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6293 A python script to validate compiler diagnostic messages. It can be
6294 used to verify that sdcc complains about bad c source code and
6295 gives a good location of the error.
6296 * support/valdiag/Makefile,
6297 * support/valdiag/valdiag.py,

6317 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
6319 * sdcc.spec: updated
6320 * device/include/Makefile.in: don't install CVS directories
6321 * device/lib/Makefile.in: added removal of CVS directories after install
6322 * doc/Makefile: fixed install, added local_icons
6323 * sim/ucsim/gui.src/Makefile.in: fixed an old typo

6328 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
6330 PIC16 port related changes:
6331 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
6332 added variable stackPos,
6334 * gen.c: genCall, assignResultValue: added support for
6335 pushing/retrieving function parameters to/from stack,
6336 genFunction,genEndFunction: setup stack frame for the
6338 genAddrOf: will be changed according to bug 863624
6340 * added files genutils.c and genutils.h which contain gen*
6341 debugged and optimised functions extracted from gen.c
6343 * glue.c: added variable 'externs' which holds extern symbols,
6344 pic16emitRegularMap: is modified to properly handle relocatable
6345 symbols under the new scheme,
6346 pic16createInterruptVect: is modified
6347 pic16printPublics: is modified to emit 'global' assembler directives,
6348 added pic16_printExterns to print extern symbols,
6349 pic16glue: initializes stack/frame pointer in the beginning of
6350 the assembly output. Temporary hack, will be corrected later,
6351 because gplink yet does not support stack and SDCC does not
6352 yet support a type of crt0.o object to create the final binary.
6354 * Removed many lines that contain 8051 legacy code.
6355 * The code is finally placed under a 'code' directive.
6356 * Added port specific options.
6358 * _process_pragma: simplified since now we do not need *special*
6359 include file to define SFR registers. But a separate header
6360 will be needed. This will be developed later.
6361 * _pic16_parseOptions: added, parses port specific options:
6362 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
6363 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
6364 --preplace-udata-with=
6366 * _pic16_setDefaultOptions: modified to initialize section names,
6367 but hack is temporarly out of order since it needs improvement.
6368 * _pic16_genAssemblerPreamble: configuration words are emitted by
6369 their address instead of their name. This part is incomplete and
6370 supports only the 18Fxx2 devices. Other devices will emit an error
6371 during assembly since they do not contain the same set of config
6373 * _pic16_genIVT: is modified,
6375 * pcode.c: added definitions for some hardware registers that are needed
6377 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
6378 All PCI entries are updated. Now LFSR is supported.
6379 * Removed pic16_pciTRIS is mentioned by mdubuc in source
6380 * added pic16_newpCodeOpLit2 to support instructions with
6381 two literal arguments
6382 * pic16_pCode2str: corrected code that emits assembler instructions
6383 with two literal operands and those that have an access bit modifier
6384 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
6385 this fixes a bug which caused some labels to be lost, when an
6386 assembler directive was added, i.e. banksel,
6387 * pic16_FixRegisterBanking: improved logic that causes the insertion
6389 * InlineFunction: functions that are called once, are not any more
6390 inlined. This can be a port option in the future,
6392 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
6394 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
6395 hold the corresponding uninitialized symbols,
6396 * pic16_allocProcessorRegister: registers have explicit marked the
6398 * pic16_allocInternalRegister: registers are explicit marked as
6400 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
6401 processing list, so bit registers were lost,
6404 * ralloc.h: added field 'accessBank' and original symbol operand
6405 in register definition,
6406 * removed the field isMapped from register definition,
6408 ** Several functions have been removed from various sources:
6409 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
6410 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
6411 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
6412 pic16_assignRelocatableRegisters
6414 ** others have been introduced:
6415 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
6416 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
6418 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
6420 * support/scripts/inc2h.pl: changed definition of BIT_AT
6421 to emit 'sbit at' instead of 'bit at'. This was a request.
6423 PIC16 port related preliminary changes:
6424 * gen.c: prefixed function popRegFromString with
6425 pic16_ and all references to it corrected
6426 * pcode.c: all pic16_pc_* hardware registers prefixed
6427 with underscore (_),
6428 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
6429 * ralloc.c: newReg(): when register is REG_SFR then
6430 set address to rIdx,
6431 pic16_allocProcessorRegister(): marks register wasUsed=0
6432 pic16_writeUsedRegs(): added a call to assign processor
6433 registers via pic16_assignFixedRegisters
6435 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
6437 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
6438 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
6439 variables in unused register banks. Also the SSEG is placed
6440 wherever there is enough space for it, and IDATA can be anywhere
6441 in internal RAM. For now compile using -Wl-Y[stack_size].
6442 The mem file is different for this option as well, since it
6443 makes no sense of talking about DSEG lenght.
6445 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
6447 * src/SDCClrange.c: fixed bug 869095 that caused segfault
6448 in certain cases, e.g. when ROM assignment, patch provided
6449 from Albert den Haan.
6451 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

6594 * src/mcs51/peephole.def,
6595 * src/ds390/peephole.def: using the atomic test and clear instruction jbc

7336 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
7337 support for standard C idiom of memory mapped variables; for
7338 example, *((xdata int*)0x1234) = 1 is now internally equivalent
7339 to xdata int at 0x1234 tempvar = 1.
7340 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
7341 provided by Akiya ISHIDA

7357 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7359 Fixed bug #621531 (const & volatile confusion in the type chain).
7360 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

7452 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
7453 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
7454 fetching of the pointer
7455 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
7456 copied from genNearPointerSet()
7457 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
7458 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
7459 If they pop r0/r1 they must be called in the opposite order than aopOp().
7460 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
7461 (resp. --stack-auto), prepared for --xstack

7470 these ports have their own __sdcc_external_start()
7472 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
7474 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7475 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
7476 type for bits was changed. It resulted in bit variables becoming
7477 global, which is not permitted in PIC 14 assembly output.
7479 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7481 * doc/sdccman.lyx: various additions and updates. Rearranged sections

7494 A few small changes that speed up the peephole optimizer.
7498 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7500 Try to make the peephole optimizer smarter by maintaining
7501 an association between the assembly source code and the
7502 iCodes that originated them. Put this information to use
7503 with a new peephole rule condition "notVolatile" so that
7504 the rules can be aggressive yet still safe.
7509 * src/mcs51/peeph.def
7511 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7515 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
7516 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
7517 if the left or right operand symbols have the accuse flag set.
7519 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7521 Changed the type of the result of the ! (NOT) operator to char;
7522 previously it returned the same type as the source. This allows
7523 us to eliminate all the genFloatNot functions (all of its target
7524 implementations were very buggy) since !float can use the same
7527 * src/SDCCicode.c (ast2iCode): ! returns char

7534 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
7536 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
7537 1. Interrupt would not compile properly. Ensure PCLATH register is saved
7538 during interrupts. Ensure WSAVE is located at a shared bank address.
7539 2. Fixed page selection in some places
7540 3. Fixed BTFSS/C to where necessary use registers directly and not simply
7541 the registers name strings.
7542 4. Fixed "signed / unsigned compare" compiler warnings.
7543 5. The PIC port manages its own allocation of the general purpose
7544 registers, but makes no attempt to reuse them. As a result when
7545 compiling it soon runs out of general purpose registers. Some
7546 additional code was added to the files pcode.c and device.c to walk
7547 through the function call tree and rename the registers so that they
7557 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
7558 genPlus() & genMinus() when the result is the same as left or right

7564 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7566 Made bitfield a distinct type from bit so that bitfields
7567 convert as per ANSI C and bits retain their traditional
7568 boolean style behaviour. Implemented bitfield support in
7576 * src/ds390/gen.c: bit v bitfield split
7577 * src/z80/gen.c: New support for bitfields
7578 * support/regression/tests/bitfields.c: reenabled z80,
7581 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
7583 Rules 246.x, 247.x relate to bitfields, the others speed up
7584 access to xdata mapped I/O devices.
7586 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
7588 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7590 Cleaned up genPackBits and genUnpackBits and added two helper
7591 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
7592 for literal assignments in genPackBits (thanks to Frieder for
7598 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7600 Fixed bug #748310 (pointer to function type mishandled when the
7601 function name is omitted). Also fixed a SIGSEGV when a function
7602 attribute (reentrant, etc) is used on a non-function or on a
7603 function but misplaced before the parameter list.
7605 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
7607 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
7608 * support/Util/SDCCerr.h,
7609 * support/Util/SDCCerr.c: Added func attr misuse error msg

7630 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7632 Made the constant following the "interrupt" keyword optional. If
7633 omitted, the function will not automatically be given an entry
7634 in the interrupt vector table (similar to #pragma NOIV, but
7635 less syntacticly kludgy). The interrupt number is also now
7636 range checked. Also fixed a bug in the high order bit example

7650 * src/SDCCicode.c (operandOperation): rewritten some ops
7651 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7652 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7654 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7655 be re-activated by defining REDUCE_LITERALS)
7656 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
7657 unsigned, but are signed by default
7658 * src/SDCCval.c (constVal): rearranged
7659 * src/SDCCval.c (valMod): preliminary fix
7660 * src/SDCCval.c (valCastLiteral): use TYPE_* types

8166 added if/endif conditional macros to remove options help
8167 messages from optionsTable when a port is not configured, added
8168 support for the PIc16 port in the ports table, when executing
8169 the compiler with no port specified on command line, a default
8170 port is selected with the new macro DEFAULT_PORT which is
8171 defined in port.h, in setDefaultOptions() linkOptions is removed
8172 from initialization assignment, since now it is a set,
8173 parseCmdLine uses setParseWithComma for linkOptions, in
8174 linkEdit() linkOptions are accessed with new function indexSet()
8175 which returns the i'th item of a set variable. See SDCCset.c, in
8176 linkEdit() when calling buildCmdLine(), added linkOptions as
8177 last argument. Now users can pass arguments to gplink via the
8178 -Wl option, main() uses pic16glue() to glue up pic16 programs

8191 * src/pic16/main.c: __config directives are commented out to stop
8192 gpasm complaining and test the linkage with gplink, _linkCmd and
8193 _asmCmd changed to be more gplink and gpasm friendly
8194 * src/pic16/peeph.def: peep rule 3 is commented out, since it
8195 produced an error when parsed, peep rule 12 is added to utilize
8196 movff, but it is commented out since the pCode does not support
8197 yet a command with 2 address arguments
8199 2003-05-18 <johan AT balder>
8201 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

9240 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
9242 2003-01-04 <johan AT balder>
9244 * src/SDCCval.c (getNelements): fixed the initialized array of structures
9246 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>

9259 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
9260 * src/mcs51/main.c: removed {bindir}{sep} from aslink
9262 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9264 * in \sdcc\as\mcs51\ changed these files in order to create an
9265 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
9266 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
9267 following files to include the previous two files: aslink.dsp,
9268 Makefile.aslink, Makefile.bcc, and Makefile.in.
9270 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
9271 .adb instead of .cdb
9273 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9275 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
9276 value from option --iram-size.
9278 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9280 * \sdcc\as\mcs51\lklist.c: added boundary check before using
9283 2002-09-18 <wiml AT hhhh.org>
9285 * SDCClrange.h: exposed setFromRange() and setToRange()
9286 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
9287 packRegsForAccUse() (bug 542397)
9288 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
9289 multiple times and emitting the fetch operations more than once
9290 added aopGetUsesAcc() function to allow binary operators to
9291 fetch their operands in the correct order; made genMinus() emit
9292 compact code for X = LITERAL - Y
9294 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9295 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
9296 sprintf() in line 1267.
9298 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9299 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
9302 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9303 Changes to aslink (All the changes are marked with 'JCF'):
9305 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
9308 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
9309 area BSEG. Also moves, if possible, the DATA area down into the internal
9310 ram so more space is available.
9312 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
9315 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
9316 not bytes. Function summary() which creates a memory usage summary
9317 file with extension .mem. Reports of overlaping stack and small stack
9318 size. If the space for the stack is less than 16 bytes aslink trows a
9321 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
9322 the 8051. Option 'y' for memory summary output file.
9324 Changes to sdcc (All the changes are marked with 'JCF'):
9326 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
9328 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
9329 overlaying area for it (uses RegBankUsed[4]).
9331 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
9332 bank zero as used by default. By default aslink locates the stack
9333 (equivalent to --stack-after-data). Pass option 'y' to aslink for
9334 the creation of the .mem file. Delegates the allocation of data area
9335 to aslink (it is not longer 0x30 by default). If --stack-loc passes
9336 the begining of the stack area to aslink.
9338 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
9339 glue() in SDCCglue.c creates an area for it.
9341 2002-09-03 Borut Razem <borut.razem AT siol.net>
9342 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
9343 sdcc/src/pic/glue.c:
9344 introduced atexit() handler for teporay files removal in case of
9345 errors, assertions, ...
9347 2002-08-29 Borut Razem <borut.razem AT siol.net>
9348 * sdcc/support/cpp2/auto-host_vc_in.h:
9349 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
9350 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
9351 Maybe there is a similar problem with BORLANDC? It should be checked!
9353 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
9354 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9355 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
9356 was not executed, and the compiler (cl) launched a warning:
9357 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
9359 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9360 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
9362 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
9363 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
9365 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9366 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
9367 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
9368 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9369 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
9370 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
9371 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
9372 - added Release configuration in VS projects
9373 - review of compiler an linker options
9374 - VC .exe files are generated in bin_vc directory, not to interfere
9375 with binaries generated from other projects (cygwin, mingw, bcc ...)
9377 * sdcc/src/yacc.dsp: added
9379 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
9380 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
9381 and insert the version number definitions from .version
9383 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
9385 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
9386 added - genarate auto-host.h using auto-host_vc_in.h as template
9389 removed from CVS, generated automatically
9391 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
9392 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
9394 2002-08-11 Borut Razem <borut.razem AT siol.net>
9395 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
9397 2002-08-10 Borut Razem <borut.razem AT siol.net>
9398 * src/SDCCmain.c (main):
9399 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
9400 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
9401 The consequence was that some temporary files were not removed.
9404 unification of code in functions tempfilename() and tempfile():
9405 function tempnam() is defined in Visual Studio 6.0 and .NET
9407 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
9409 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
9410 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
9411 - removed compiler command line option /WX: Treats all warnings as errors
9412 - update a list of source files, included into the project
9414 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
9415 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
9416 changed project type to Generic Project so that can be correcly converted to VS.NET project
9418 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
9420 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
9422 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
9424 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
9425 added return 0 statements after assert() to make compiler happy
9427 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
9428 added newline in the def file to keep MSC compiler satisfied
9430 * sdcc/src/z80/gen.c:
9431 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
9432 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
9433 - solved MSC error in function aopDump()
9435 * sdcc_vc.h: define PREFIX as "\\sdcc"
9437 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
9438 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
9440 2002-06-22 Scott Dattalo <scott AT dattalo.com>
9441 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
9442 - Rewrote the register banking algorithm.
9443 - Added pCode live-range analysis to registers (for now, only non-used and
9444 singly-used registers optimized away)
9446 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
9448 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba AT cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.

9477 2002-03-28 Johan Knol <johan AT balder>
9479 * src/SDCCval.c: fixed bug #532436
9481 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9483 Added "char *Processor" field to the port structure.
9486 Added -p option. Allows port dependent processor to be specified.
9489 Initialized the new field char *Processor field to NULL in all ports
9492 Compiler generated registers for interrupt context saving
9493 were not getting allocated.
9495 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
9498 Fixed left shift. Will promote the left side of a left shift
9499 if a) left shifting more than size of operand or b) when assigned
9500 to something size > size of left side
9502 2002-03-14 Scott Dattalo <scott AT dattalo.com>
9504 tons of changes. Register allocation has been
9505 rewritten. Added customization for the various PICs. Flow
9506 analysis is restructured. ...
9512 Added. device.c is a PIC port hack to accomodate variations
9515 2002-03-13 Michael Hope <michaelh AT vroom>
9517 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
9519 2002-03-04 johanknol <johanknol AT manik>
