1389 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1391 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1392 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1394 One basic decision: e.g. src/clean.mk includes further files. In order
1395 to make this work there are two solutions:
1396 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1397 run configure on them. This way they can use
1398 'include $(srcdir)/port-clean.mk'
1399 - always include clean.mk by the Makefile at the same level. To avoid
1400 that `make clean` tries to include and build Makefile.dep the
1401 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1402 implemented, because now even `make uninstall` doesn't create
1403 Makefile.in. clean.mk could be eliminated by pasting it in
1406 * debugger/mcs51/Makefile.in: build own objects from library sources
1407 (SLIB, SDCC) in current directory
1409 * configure, configure.in: renamed --disable-device-lib-build in
1410 --disable-device-lib; added --enable-doc, the required tools are
1411 searched by configure; added result message; the toolchain for the
1412 belonging ports are now only built, if the port is enabled.
1414 * support/regression/*: all output is written in directory gen, because
1415 the fwk and ports directories don't livet in the build tree using vpath
1417 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1418 --disable-device-lib, added --enable-doc, added section VPATH
1420 * sim/ucsim/configure.in,
1421 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1422 z80 are enabled by default
1424 2006-04-24 Raphael Neider <rneider AT web.de>
1426 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1427 to config word, "pic14_"-prefixed some extern functions
1428 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1429 config word has been found
1430 * src/pic/device.h: added prototypes

1739 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1740 call to allocReg, not by manually allocating a new one,
1741 (pic16_assignRegisters): now before going through the register
1742 allocating functions mark all registers as free. This eliminates some
1743 side effects resulting from peephole parser done earlier in the backbone

1793 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1795 2006-03-06 Borut Razem <borut.razem AT siol.net>
1797 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1798 made the linker quiet
1800 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1802 * src/pic16/gen.c (genPcall): fixed bug #1443644
1803 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1804 which dumps before the function entry point a data byte which represents
1805 the number of the local variables used by the specified function, added
1806 'xinst' for initial support for Extended Instruction Support,
1807 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1808 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1809 port->fun_prefix anymore (may change later),
1810 (genFunction, genEndFunction): do not store/restore local registers for
1811 _main (this should take care the --main-return command line option in
1813 (genOr): removed some legacy pic-port instructions,
1814 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1815 performing operations with SFR's causes data to be written more than
1816 once to each SFR. Perhaps SFRs should be handled in special cases...
1817 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1819 * src/pic16/main.c (_process_pragma): stack bound checking did not take

1821 (struct OPTIONS pic16_optionsTable): added command line argument
1822 --extended or -y for Extended Instruction Support,
1823 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1824 (deassignLRs): *** perhaps the most important change, old 'for' code
1825 (commented out for reference), didn't account for some registers which
1826 were left marked 'not free' after a pointer operation. The change
1827 reduces register usage a lot in some cases

4100 * src/SDCCglobal.h (struct options),
4102 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4103 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4104 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4105 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4106 always available in leading double underscore form. The C99 support is
4107 mostly missing, but it's a start.
4108 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4109 reserved identifier "__data".

4187 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4189 * device/lib/printf_large.c: removed inline assembly for portability and
4190 readability. Use printf_fast if speed or size are more important.
4191 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4192 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4194 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4196 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4197 prevent compiler warning
4199 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4201 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4202 moved to level 0 and declared as static. Also they are explicit
4203 placed in access bank. This was necessery because some times they
4204 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4205 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4206 optimizations. Currently only compare to unsigned char is implemented,
4207 * src/pic16/gen.c: added fReturnIdx array,
4208 * (struct resolvedIfx) is moved to gen.h and made public,
4209 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4210 * (aopForSym): added an optimization to directly store in stack of
4211 the operand of a SEND iCode,
4212 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4213 but as registers instead (AOP_REG) using the fReturnIdx array,
4214 * (pic16_freeAsmop): remove the freed register from the
4215 _G.sregsAlloc field,
4216 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4217 a compare of 'WREG',
4218 * (pic16_popGetTempRegCond): changed function prototype, now
4219 function takes also a bitVector argument v which holds the current
4220 set of registers that are allocated for stack access by aopForSym,
4221 registers allocated in aopForSym for accessing stack symbols are not
4222 any more part of the functions usedRegs field,
4223 * (genCall): some times aopOp is called for a stack variable to be
4224 send, aopForSym might perform the push, if this is true make sure
4225 that genCall doesn't push the variable twice by testing _G.resDirect,
4226 * (genFunction): changed testing for unspecified interrupt number
4227 from 256 to INTNO_UNSPEC,
4228 * modified selection scheme of frame pointer generation. Previously
4229 if function did use local registers a frame pointer was generated,
4230 now a frame pointer is generated only if function has arguments
4231 (that need PLUSW2 register access), or has stack arguments, or the
4232 compiler is not instructed to omit the frame pointer,
4233 * (genEndFunction): before restoring local registers that were saved
4234 in the function preamble, also restore the registers that *might*
4235 have been allocated for stack access,
4236 * (genRet): removed some old comments,
4237 * (genCmp, the active (RN's) version): added a call to the
4238 pic16_genCmp_special function to perform the compare with a more
4239 robust and optimized way,
4240 * (genInline): a feature has been added in inline code generation,
4241 which allows a wildcard variable substitution when writing inline
4242 assembly. Code is incomplete and experimental therefore undocumented,
4243 * (genCast): changed order of aopOp for result and right to allow
4244 aopForSym to directly load the result if possible,
4245 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4246 perform an optimized compare on some selected special occasions,
4247 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4248 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4249 generate an IVT any more,
4250 * src/pic16/main.c (pic16_optionsTable): added command line option
4252 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4253 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4255 * src/pic16/NOTES: Raphael Neider added in list of active developers
4256 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4257 jumptable_end to prevent bug #,
4258 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4259 inCond and outCond fields,
4260 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4261 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4262 turn off register spilling,
4263 * (packRegsForOneUse): synced with other ports' versions although it
4264 is not used currently,
4265 * (pic16_packRegisters): added an optimization while reading
4266 structure bitfields, some registers may be saved (malloc code is
4267 decreased by 80 bytes)
4269 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4271 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4272 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4273 this can be optimized more?
4275 2005-03-10 Raphael Neider <rneider AT web.de>
4277 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4278 genNearPointerGet): (hopefully) fixed access to bitfields via
4279 pointers (p->bitN = x; and x = p->bitN; failed)
4281 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4283 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4913 Adding support for replacing ljmps with sjmps in jumptables
4914 generated for switch statements. For now you need to set the
4915 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4916 Now 4 algorithms for mcs51 jumptable generation are used:
4917 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4918 addresses loaded pc-relative for up to 112 cases and stack-pushing
4919 target addresses loaded with offset from dptr for up to 256 cases.

4949 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4951 * added libc directory. The current version of LibC contains string
4952 functions, ctype functions and macros and some functions of the
4953 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4954 be extensively tested in the future. Standard disclaimer here.
4955 Library is not automatically build yet. But one can build it by
4956 invoking 'make' inside the libc directory.

4967 * (pic16_storeForReturn): optimized return of 0,
4968 * (genCmp): experimental code for new genCmp which uses PIC18's
4969 special compare&skip instructions. Initial tests fail some times
4970 with variables grater than 1 byte in size, so new code is disabled,
4971 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4973 * (genCast): began a fix to optimize the casting of a bit to another
4974 bit, now assigning a bitfield to another bitfield will fail, sorry,
4975 * src/pic16/main.c: disabled the use of lr-support feature,
4976 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

4983 and 1 for banking instruction,
4984 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4985 caused stop processing pCodes after a inline assembly block,
4986 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4987 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4988 registers when it shouldn't,
4989 * src/pic16/ralloc.c (allocReg): add preliminary support for
4990 supporting a limited set of temporary registers,
4992 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4994 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
4995 genDataPointerSet): ensure assignments always copy in MSB to LSB
4997 (loadRegFromAop): recognize CLRH optimization,
4998 (genFunction): optimize RECEIVE iCodes in reentrant functions
5000 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5002 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8000 loaded with the linker search paths (-L arguments) and the libraries
8001 to be linked with the current source (-l arguments). Changes
8002 currently will affect only the pic16 port.
8003 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8004 include path the port specific paths and port specific libraries,
8005 * gplink command now contains the $3 argument,

8023 Documenting changes from previous commits.
8024 * configure.in (version 1.56),
8025 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8026 when generating output files to configure the pic16 library,
8027 but now I've commented it out, since gputils aren't installed in the
8028 SF compile farm, so library won't compile
8030 * device/lib/Makefile.in (version 1.56): initially I've added in
8031 target 'all' the prerequestive 'model-pic16' so it compiled the
8032 pic16 library, but now I've commented it out for the same reasons
8034 * added targets 'model-pic16' and 'objects-pic16' to compile the
8036 * added target 'port-specific-objects-pic16' to handle the
8037 generated libraries and copy them into the build/ directory
8038 * added target 'clean-intermediate-pic16' to clean intermediate
8039 files into pic16 directory
8040 * in target 'installdirs' added line to create directory pic16 in

8044 added lines to copy all header files to installation path,
8045 * in target 'installdirs' added line create directory for pic16
8046 headers in the installation path

8328 * src/ds390/gen.c (genRightShift): fixed bug #870788
8329 * src/SDCCast.c (decorateType): fixed bug #870781
8331 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8333 PIC16 port related changes:
8334 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8335 added variable stackPos,
8337 * gen.c: genCall, assignResultValue: added support for
8338 pushing/retrieving function parameters to/from stack,
8339 genFunction,genEndFunction: setup stack frame for the
8341 genAddrOf: will be changed according to bug 863624
8343 * added files genutils.c and genutils.h which contain gen*
8344 debugged and optimised functions extracted from gen.c
8346 * glue.c: added variable 'externs' which holds extern symbols,
8347 pic16emitRegularMap: is modified to properly handle relocatable
8348 symbols under the new scheme,
8349 pic16createInterruptVect: is modified
8350 pic16printPublics: is modified to emit 'global' assembler directives,
8351 added pic16_printExterns to print extern symbols,
8352 pic16glue: initializes stack/frame pointer in the beginning of
8353 the assembly output. Temporary hack, will be corrected later,
8354 because gplink yet does not support stack and SDCC does not
8355 yet support a type of crt0.o object to create the final binary.
8357 * Removed many lines that contain 8051 legacy code.
8358 * The code is finally placed under a 'code' directive.
8359 * Added port specific options.
8361 * _process_pragma: simplified since now we do not need *special*
8362 include file to define SFR registers. But a separate header
8363 will be needed. This will be developed later.
8364 * _pic16_parseOptions: added, parses port specific options:
8365 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8366 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8367 --preplace-udata-with=
8369 * _pic16_setDefaultOptions: modified to initialize section names,
8370 but hack is temporarly out of order since it needs improvement.
8371 * _pic16_genAssemblerPreamble: configuration words are emitted by
8372 their address instead of their name. This part is incomplete and
8373 supports only the 18Fxx2 devices. Other devices will emit an error
8374 during assembly since they do not contain the same set of config
8376 * _pic16_genIVT: is modified,
8378 * pcode.c: added definitions for some hardware registers that are needed
8380 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8381 All PCI entries are updated. Now LFSR is supported.
8382 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8383 * added pic16_newpCodeOpLit2 to support instructions with
8384 two literal arguments
8385 * pic16_pCode2str: corrected code that emits assembler instructions
8386 with two literal operands and those that have an access bit modifier
8387 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8388 this fixes a bug which caused some labels to be lost, when an
8389 assembler directive was added, i.e. banksel,
8390 * pic16_FixRegisterBanking: improved logic that causes the insertion
8392 * InlineFunction: functions that are called once, are not any more
8393 inlined. This can be a port option in the future,
8395 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8397 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8398 hold the corresponding uninitialized symbols,
8399 * pic16_allocProcessorRegister: registers have explicit marked the
8401 * pic16_allocInternalRegister: registers are explicit marked as
8403 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8404 processing list, so bit registers were lost,
8407 * ralloc.h: added field 'accessBank' and original symbol operand
8408 in register definition,
8409 * removed the field isMapped from register definition,
8411 ** Several functions have been removed from various sources:
8412 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8413 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8414 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8415 pic16_assignRelocatableRegisters
8417 ** others have been introduced:
8418 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8419 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8421 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8423 * support/scripts/inc2h.pl: changed definition of BIT_AT
8424 to emit 'sbit at' instead of 'bit at'. This was a request.
8426 PIC16 port related preliminary changes:
8427 * gen.c: prefixed function popRegFromString with
8428 pic16_ and all references to it corrected
8429 * pcode.c: all pic16_pc_* hardware registers prefixed
8430 with underscore (_),
8431 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8432 * ralloc.c: newReg(): when register is REG_SFR then
8433 set address to rIdx,
8434 pic16_allocProcessorRegister(): marks register wasUsed=0
8435 pic16_writeUsedRegs(): added a call to assign processor
8436 registers via pic16_assignFixedRegisters
8438 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8440 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8441 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8442 variables in unused register banks. Also the SSEG is placed
8443 wherever there is enough space for it, and IDATA can be anywhere
8444 in internal RAM. For now compile using -Wl-Y[stack_size].
8445 The mem file is different for this option as well, since it
8446 makes no sense of talking about DSEG lenght.
8448 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8450 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8451 in certain cases, e.g. when ROM assignment, patch provided
8452 from Albert den Haan.
8454 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8693 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8695 * src/SDCCast.c (decorateType): disabled a transformation I added in
8696 revision 1.188 (access to fields of a structure at an absolute address);
8697 it breaks with bitfields, extern declarations, and gcse analysis.
8698 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8699 could be assigned through a pointer, so don't complain.
8700 * src/SDCCast.c (astErrors),
8702 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

9340 support for standard C idiom of memory mapped variables; for
9341 example, *((xdata int*)0x1234) = 1 is now internally equivalent
9342 to xdata int at 0x1234 tempvar = 1.
9343 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
9344 provided by Akiya ISHIDA

9360 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9362 Fixed bug #621531 (const & volatile confusion in the type chain).
9363 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
9364 refer to the const or volatile state of the pointer itself.

9455 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9456 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9457 fetching of the pointer
9458 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9459 copied from genNearPointerSet()
9460 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9461 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9462 If they pop r0/r1 they must be called in the opposite order than aopOp().
9463 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"

9475 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9477 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9478 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9479 type for bits was changed. It resulted in bit variables becoming
9480 global, which is not permitted in PIC 14 assembly output.
9482 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9484 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9497 A few small changes that speed up the peephole optimizer.
9501 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9503 Try to make the peephole optimizer smarter by maintaining
9504 an association between the assembly source code and the
9505 iCodes that originated them. Put this information to use
9506 with a new peephole rule condition "notVolatile" so that
9507 the rules can be aggressive yet still safe.
9512 * src/mcs51/peeph.def
9514 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9518 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9519 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9520 if the left or right operand symbols have the accuse flag set.
9522 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9524 Changed the type of the result of the ! (NOT) operator to char;
9525 previously it returned the same type as the source. This allows
9526 us to eliminate all the genFloatNot functions (all of its target
9527 implementations were very buggy) since !float can use the same

9539 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9540 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9541 during interrupts. Ensure WSAVE is located at a shared bank address.
9542 2. Fixed page selection in some places
9543 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9544 the registers name strings.
9545 4. Fixed "signed / unsigned compare" compiler warnings.
9546 5. The PIC port manages its own allocation of the general purpose
9547 registers, but makes no attempt to reuse them. As a result when
9548 compiling it soon runs out of general purpose registers. Some
9549 additional code was added to the files pcode.c and device.c to walk
9550 through the function call tree and rename the registers so that they
9560 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9561 genPlus() & genMinus() when the result is the same as left or right

9567 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9569 Made bitfield a distinct type from bit so that bitfields
9570 convert as per ANSI C and bits retain their traditional
9571 boolean style behaviour. Implemented bitfield support in
9579 * src/ds390/gen.c: bit v bitfield split
9580 * src/z80/gen.c: New support for bitfields
9581 * support/regression/tests/bitfields.c: reenabled z80,
9584 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9586 Rules 246.x, 247.x relate to bitfields, the others speed up
9587 access to xdata mapped I/O devices.
9589 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9591 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9593 Cleaned up genPackBits and genUnpackBits and added two helper
9594 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9595 for literal assignments in genPackBits (thanks to Frieder for
9601 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9603 Fixed bug #748310 (pointer to function type mishandled when the
9604 function name is omitted). Also fixed a SIGSEGV when a function
9605 attribute (reentrant, etc) is used on a non-function or on a
9606 function but misplaced before the parameter list.
9608 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9610 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9611 * support/Util/SDCCerr.h,
9612 * support/Util/SDCCerr.c: Added func attr misuse error msg

9633 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9635 Made the constant following the "interrupt" keyword optional. If
9636 omitted, the function will not automatically be given an entry
9637 in the interrupt vector table (similar to #pragma NOIV, but
9638 less syntacticly kludgy). The interrupt number is also now
9639 range checked. Also fixed a bug in the high order bit example

9653 * src/SDCCicode.c (operandOperation): rewritten some ops
9654 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9655 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9657 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9658 be re-activated by defining REDUCE_LITERALS)
9659 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9660 unsigned, but are signed by default
9661 * src/SDCCval.c (constVal): rearranged
9662 * src/SDCCval.c (valMod): preliminary fix
9663 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10170 messages from optionsTable when a port is not configured, added
10171 support for the PIc16 port in the ports table, when executing
10172 the compiler with no port specified on command line, a default
10173 port is selected with the new macro DEFAULT_PORT which is
10174 defined in port.h, in setDefaultOptions() linkOptions is removed
10175 from initialization assignment, since now it is a set,
10176 parseCmdLine uses setParseWithComma for linkOptions, in
10177 linkEdit() linkOptions are accessed with new function indexSet()
10178 which returns the i'th item of a set variable. See SDCCset.c, in
10179 linkEdit() when calling buildCmdLine(), added linkOptions as
10180 last argument. Now users can pass arguments to gplink via the
10181 -Wl option, main() uses pic16glue() to glue up pic16 programs

10195 gpasm complaining and test the linkage with gplink, _linkCmd and
10196 _asmCmd changed to be more gplink and gpasm friendly
10197 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10198 produced an error when parsed, peep rule 12 is added to utilize
10199 movff, but it is commented out since the pCode does not support
10200 yet a command with 2 address arguments
10202 2003-05-18 <johan AT balder>
10204 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11222 2003-01-07 <johan AT balder>
11224 * src/SDCCast.c (decorateType): fixed bug #600035
11226 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
11227 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
11228 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
11229 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
11230 * src/pic/pcode.c: outcommented unused variable to remove warnings

11237 2003-01-06 <johan AT balder>
11239 * src/SDCCicode.c: fixed array add
11241 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11242 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
11243 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
11245 2003-01-04 <johan AT balder>
11247 * src/SDCCval.c (getNelements): fixed the initialized array of structures
11249 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11250 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
11252 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11253 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
11254 * support/regression/tests/bug-524697.c: fit mem usage into 8032
11256 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11257 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11259 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11260 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11262 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11263 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11265 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11267 * in /sdcc/as/mcs51/ changed these files in order to create an
11268 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11269 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11270 following files to include the previous two files: aslink.dsp,
11271 Makefile.aslink, Makefile.bcc, and Makefile.in.
11273 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11274 .adb instead of .cdb
11276 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11278 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11279 value from option --iram-size.
11281 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11283 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11286 2002-09-18 <wiml AT hhhh.org>
11288 * SDCClrange.h: exposed setFromRange() and setToRange()
11289 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11290 packRegsForAccUse() (bug 542397)
11291 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11292 multiple times and emitting the fetch operations more than once
11293 added aopGetUsesAcc() function to allow binary operators to
11294 fetch their operands in the correct order; made genMinus() emit
11295 compact code for X = LITERAL - Y
11297 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11298 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11299 sprintf() in line 1267.
11301 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11302 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11305 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11306 Changes to aslink (All the changes are marked with 'JCF'):
11308 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11311 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11312 area BSEG. Also moves, if possible, the DATA area down into the internal
11313 ram so more space is available.
11315 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11318 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11319 not bytes. Function summary() which creates a memory usage summary
11320 file with extension .mem. Reports of overlaping stack and small stack
11321 size. If the space for the stack is less than 16 bytes aslink trows a
11324 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11325 the 8051. Option 'y' for memory summary output file.
11327 Changes to sdcc (All the changes are marked with 'JCF'):
11329 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11331 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11332 overlaying area for it (uses RegBankUsed[4]).
11334 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11335 bank zero as used by default. By default aslink locates the stack
11336 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11337 the creation of the .mem file. Delegates the allocation of data area
11338 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11339 the begining of the stack area to aslink.
11341 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11342 glue() in SDCCglue.c creates an area for it.
11344 2002-09-03 Borut Razem <borut.razem AT siol.net>
11345 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11346 sdcc/src/pic/glue.c:
11347 introduced atexit() handler for teporay files removal in case of
11348 errors, assertions, ...
11350 2002-08-29 Borut Razem <borut.razem AT siol.net>
11351 * sdcc/support/cpp2/auto-host_vc_in.h:
11352 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11353 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11354 Maybe there is a similar problem with BORLANDC? It should be checked!
11356 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11357 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11358 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11359 was not executed, and the compiler (cl) launched a warning:
11360 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11362 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11363 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11365 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11366 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11368 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11369 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11370 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11371 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11372 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11373 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11374 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11375 - added Release configuration in VS projects
11376 - review of compiler an linker options
11377 - VC .exe files are generated in bin_vc directory, not to interfere
11378 with binaries generated from other projects (cygwin, mingw, bcc ...)
11380 * sdcc/src/yacc.dsp: added
11382 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11383 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11384 and insert the version number definitions from .version
11386 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11388 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11389 added - genarate auto-host.h using auto-host_vc_in.h as template
11392 removed from CVS, generated automatically
11394 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11395 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11397 2002-08-11 Borut Razem <borut.razem AT siol.net>
11398 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11400 2002-08-10 Borut Razem <borut.razem AT siol.net>
11401 * src/SDCCmain.c (main):
11402 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11403 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11404 The consequence was that some temporary files were not removed.
11407 unification of code in functions tempfilename() and tempfile():
11408 function tempnam() is defined in Visual Studio 6.0 and .NET
11410 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11412 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11413 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11414 - removed compiler command line option /WX: Treats all warnings as errors
11415 - update a list of source files, included into the project
11417 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11418 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11419 changed project type to Generic Project so that can be correcly converted to VS.NET project
11421 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11423 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11425 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11427 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11428 added return 0 statements after assert() to make compiler happy
11430 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11431 added newline in the def file to keep MSC compiler satisfied
11433 * sdcc/src/z80/gen.c:
11434 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11435 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11436 - solved MSC error in function aopDump()
11438 * sdcc_vc.h: define PREFIX as "\\sdcc"
11440 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11441 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11443 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11444 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11445 - Rewrote the register banking algorithm.
11446 - Added pCode live-range analysis to registers (for now, only non-used and
11447 singly-used registers optimized away)
11449 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11451 * 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.

11468 * device/lib/z80/printf.c (sprintf): Added.
11470 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11472 * src/z80/peeph.def: Added transpose redundent load rule.
11474 * src/z80/main.c: Added force callee saves for jaune.
11476 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11478 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11480 2002-03-28 Johan Knol <johan AT balder>
11482 * src/SDCCval.c: fixed bug #532436
11484 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11486 Added "char *Processor" field to the port structure.
11489 Added -p option. Allows port dependent processor to be specified.
11492 Initialized the new field char *Processor field to NULL in all ports
11495 Compiler generated registers for interrupt context saving
11496 were not getting allocated.
11498 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11501 Fixed left shift. Will promote the left side of a left shift
11502 if a) left shifting more than size of operand or b) when assigned
11503 to something size > size of left side
11505 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11507 tons of changes. Register allocation has been
11508 rewritten. Added customization for the various PICs. Flow
11509 analysis is restructured. ...
11511 * src/pic/device.h:
11514 * src/pic/device.c:
11515 Added. device.c is a PIC port hack to accomodate variations
11518 2002-03-13 Michael Hope <michaelh AT vroom>
11520 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11522 2002-03-04 johanknol <johanknol AT manik>
11524 * /src/SDCCval.c: fixed
11526 const unsigned char arr[][2] = { { 0, 1 } };
11527 t18.c:1: error: Initializer element is not constant

11587 2002-03-01 <johan AT FRIJA>
11589 * src/SDCCglue.c (printIvalPtr): fixed bug #524211
11591 * src/SDCCast.c (decorateType): fixed bug #524209

11613 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11615 * sdcc/src/SDCCloop.c:
11616 Previous fix was not good. basic blocks that have "break" or "return" are
11617 not really partof a loop , but live ranges used in these blocks should
11618 be live thru the entire loop, so set partOfLoop but don't add them to
11621 2002-02-21 <johan AT FRIJA>
11623 * src/SDCCcse.c: fixed bug #514308
11625 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11628 Fixed BUG #519583. If a conditional block ended in a return/break
11629 statement inside a loop, it was not being considered part of the loop.
11631 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11633 2002-02-10 Karl Bongers <karl AT turbobit.com>

11637 with lots of comments and notes.
11639 * device/examples/test2.c:
11640 Fix bug, "red" variable not being initialized(compiler complained).
11642 * device/examples/Makefile, examples/test3.c:
11643 Add Makefile in device/examples folder, compiles test3.c
11644 for use as a multiple module SDCDB test case.
11646 * sim/ucsim/cmd.src/cmdset.cc:
11647 Took out debug printfs in ucsim "next" command.
11649 * sim/ucsim/xa.src:
11650 Karl and Johan start ucsim XA support. Most dissassembly working,
11651 about 75% emulation done(plenty of work remaining).
11653 * sim/ucsim/z80.src:
11654 Add Z80 support to ucsim, add test-ucz80 regression test,
11655 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
11656 Notice z80 compiler fails on examples/test3.c/crc code.
11658 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
11660 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
11661 Added support for --parms-in-bank1
