1394 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1396 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1397 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1399 One basic decision: e.g. src/clean.mk includes further files. In order
1400 to make this work there are two solutions:
1401 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1402 run configure on them. This way they can use
1403 'include $(srcdir)/port-clean.mk'
1404 - always include clean.mk by the Makefile at the same level. To avoid
1405 that `make clean` tries to include and build Makefile.dep the
1406 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1407 implemented, because now even `make uninstall` doesn't create
1408 Makefile.in. clean.mk could be eliminated by pasting it in
1411 * debugger/mcs51/Makefile.in: build own objects from library sources
1412 (SLIB, SDCC) in current directory
1414 * configure, configure.in: renamed --disable-device-lib-build in
1415 --disable-device-lib; added --enable-doc, the required tools are
1416 searched by configure; added result message; the toolchain for the
1417 belonging ports are now only built, if the port is enabled.
1419 * support/regression/*: all output is written in directory gen, because
1420 the fwk and ports directories don't livet in the build tree using vpath
1422 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1423 --disable-device-lib, added --enable-doc, added section VPATH
1425 * sim/ucsim/configure.in,
1426 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1427 z80 are enabled by default
1429 2006-04-24 Raphael Neider <rneider AT web.de>
1431 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1432 to config word, "pic14_"-prefixed some extern functions
1433 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1434 config word has been found
1435 * src/pic/device.h: added prototypes

1744 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1745 call to allocReg, not by manually allocating a new one,
1746 (pic16_assignRegisters): now before going through the register
1747 allocating functions mark all registers as free. This eliminates some
1748 side effects resulting from peephole parser done earlier in the backbone

1798 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1800 2006-03-06 Borut Razem <borut.razem AT siol.net>
1802 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1803 made the linker quiet
1805 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1807 * src/pic16/gen.c (genPcall): fixed bug #1443644
1808 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1809 which dumps before the function entry point a data byte which represents
1810 the number of the local variables used by the specified function, added
1811 'xinst' for initial support for Extended Instruction Support,
1812 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1813 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1814 port->fun_prefix anymore (may change later),
1815 (genFunction, genEndFunction): do not store/restore local registers for
1816 _main (this should take care the --main-return command line option in
1818 (genOr): removed some legacy pic-port instructions,

1820 performing operations with SFR's causes data to be written more than

1827 --extended or -y for Extended Instruction Support,
1828 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1829 (deassignLRs): *** perhaps the most important change, old 'for' code
1830 (commented out for reference), didn't account for some registers which
1831 were left marked 'not free' after a pointer operation. The change
1832 reduces register usage a lot in some cases

4105 * src/SDCCglobal.h (struct options),
4107 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4108 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4109 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4110 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4111 always available in leading double underscore form. The C99 support is
4112 mostly missing, but it's a start.
4113 * support/regression/tests/bug-227710.c: fixed nonconforming use of

4192 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4194 * device/lib/printf_large.c: removed inline assembly for portability and
4195 readability. Use printf_fast if speed or size are more important.
4196 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4197 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4199 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4201 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4202 prevent compiler warning
4204 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4206 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4207 moved to level 0 and declared as static. Also they are explicit
4208 placed in access bank. This was necessery because some times they
4209 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4210 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4211 optimizations. Currently only compare to unsigned char is implemented,
4212 * src/pic16/gen.c: added fReturnIdx array,
4213 * (struct resolvedIfx) is moved to gen.h and made public,
4214 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4215 * (aopForSym): added an optimization to directly store in stack of
4216 the operand of a SEND iCode,
4217 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4218 but as registers instead (AOP_REG) using the fReturnIdx array,
4219 * (pic16_freeAsmop): remove the freed register from the
4220 _G.sregsAlloc field,
4221 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4222 a compare of 'WREG',
4223 * (pic16_popGetTempRegCond): changed function prototype, now
4224 function takes also a bitVector argument v which holds the current
4225 set of registers that are allocated for stack access by aopForSym,
4226 registers allocated in aopForSym for accessing stack symbols are not
4227 any more part of the functions usedRegs field,
4228 * (genCall): some times aopOp is called for a stack variable to be
4229 send, aopForSym might perform the push, if this is true make sure
4230 that genCall doesn't push the variable twice by testing _G.resDirect,
4231 * (genFunction): changed testing for unspecified interrupt number
4232 from 256 to INTNO_UNSPEC,
4233 * modified selection scheme of frame pointer generation. Previously
4234 if function did use local registers a frame pointer was generated,
4235 now a frame pointer is generated only if function has arguments
4236 (that need PLUSW2 register access), or has stack arguments, or the
4237 compiler is not instructed to omit the frame pointer,
4238 * (genEndFunction): before restoring local registers that were saved
4239 in the function preamble, also restore the registers that *might*
4240 have been allocated for stack access,
4241 * (genRet): removed some old comments,
4242 * (genCmp, the active (RN's) version): added a call to the
4243 pic16_genCmp_special function to perform the compare with a more
4244 robust and optimized way,
4245 * (genInline): a feature has been added in inline code generation,
4246 which allows a wildcard variable substitution when writing inline
4247 assembly. Code is incomplete and experimental therefore undocumented,
4248 * (genCast): changed order of aopOp for result and right to allow
4249 aopForSym to directly load the result if possible,
4250 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4251 perform an optimized compare on some selected special occasions,
4252 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4253 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4254 generate an IVT any more,
4255 * src/pic16/main.c (pic16_optionsTable): added command line option
4257 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4258 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4260 * src/pic16/NOTES: Raphael Neider added in list of active developers
4261 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4262 jumptable_end to prevent bug #,
4263 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4264 inCond and outCond fields,
4265 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4266 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4267 turn off register spilling,
4268 * (packRegsForOneUse): synced with other ports' versions although it
4269 is not used currently,
4270 * (pic16_packRegisters): added an optimization while reading
4271 structure bitfields, some registers may be saved (malloc code is
4272 decreased by 80 bytes)
4274 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4276 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4277 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4278 this can be optimized more?
4280 2005-03-10 Raphael Neider <rneider AT web.de>
4282 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4283 genNearPointerGet): (hopefully) fixed access to bitfields via
4284 pointers (p->bitN = x; and x = p->bitN; failed)
4286 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4288 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"

4300 * support/regression/tests/critical.c: check bug 1144613
4302 2005-03-02 Raphael Neider <rneider AT web.de>

4918 Adding support for replacing ljmps with sjmps in jumptables
4919 generated for switch statements. For now you need to set the
4920 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4921 Now 4 algorithms for mcs51 jumptable generation are used:
4922 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4923 addresses loaded pc-relative for up to 112 cases and stack-pushing
4924 target addresses loaded with offset from dptr for up to 256 cases.

4954 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4956 * added libc directory. The current version of LibC contains string
4957 functions, ctype functions and macros and some functions of the
4958 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4959 be extensively tested in the future. Standard disclaimer here.
4960 Library is not automatically build yet. But one can build it by
4961 invoking 'make' inside the libc directory.

4972 * (pic16_storeForReturn): optimized return of 0,
4973 * (genCmp): experimental code for new genCmp which uses PIC18's
4974 special compare&skip instructions. Initial tests fail some times
4975 with variables grater than 1 byte in size, so new code is disabled,
4976 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4978 * (genCast): began a fix to optimize the casting of a bit to another
4979 bit, now assigning a bitfield to another bitfield will fail, sorry,

4988 and 1 for banking instruction,
4989 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4990 caused stop processing pCodes after a inline assembly block,
4991 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
4992 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
4993 registers when it shouldn't,
4994 * src/pic16/ralloc.c (allocReg): add preliminary support for
4995 supporting a limited set of temporary registers,
4997 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4999 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

5003 (genFunction): optimize RECEIVE iCodes in reentrant functions
5005 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5007 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8002 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8004 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8005 loaded with the linker search paths (-L arguments) and the libraries
8006 to be linked with the current source (-l arguments). Changes
8007 currently will affect only the pic16 port.
8008 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8009 include path the port specific paths and port specific libraries,
8010 * gplink command now contains the $3 argument,
8011 * src/pic16/device.h,
8012 * src/pic16/device.c,: structure PIC_device is made public and

8028 Documenting changes from previous commits.
8029 * configure.in (version 1.56),
8030 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8031 when generating output files to configure the pic16 library,
8032 but now I've commented it out, since gputils aren't installed in the
8033 SF compile farm, so library won't compile
8035 * device/lib/Makefile.in (version 1.56): initially I've added in
8036 target 'all' the prerequestive 'model-pic16' so it compiled the
8037 pic16 library, but now I've commented it out for the same reasons
8039 * added targets 'model-pic16' and 'objects-pic16' to compile the
8041 * added target 'port-specific-objects-pic16' to handle the
8042 generated libraries and copy them into the build/ directory
8043 * added target 'clean-intermediate-pic16' to clean intermediate
8044 files into pic16 directory
8045 * in target 'installdirs' added line to create directory pic16 in

8049 added lines to copy all header files to installation path,
8050 * in target 'installdirs' added line create directory for pic16
8051 headers in the installation path

8067 option so that it actually works. Made it specific to the z80, since
8068 the gbz80 doesn't have these kinds of I/O ports.
8070 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8333 * src/ds390/gen.c (genRightShift): fixed bug #870788
8334 * src/SDCCast.c (decorateType): fixed bug #870781
8336 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8338 PIC16 port related changes:
8339 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8340 added variable stackPos,
8342 * gen.c: genCall, assignResultValue: added support for
8343 pushing/retrieving function parameters to/from stack,
8344 genFunction,genEndFunction: setup stack frame for the
8346 genAddrOf: will be changed according to bug 863624
8348 * added files genutils.c and genutils.h which contain gen*
8349 debugged and optimised functions extracted from gen.c
8351 * glue.c: added variable 'externs' which holds extern symbols,
8352 pic16emitRegularMap: is modified to properly handle relocatable
8353 symbols under the new scheme,
8354 pic16createInterruptVect: is modified
8355 pic16printPublics: is modified to emit 'global' assembler directives,
8356 added pic16_printExterns to print extern symbols,
8357 pic16glue: initializes stack/frame pointer in the beginning of
8358 the assembly output. Temporary hack, will be corrected later,
8359 because gplink yet does not support stack and SDCC does not
8360 yet support a type of crt0.o object to create the final binary.
8362 * Removed many lines that contain 8051 legacy code.
8363 * The code is finally placed under a 'code' directive.
8364 * Added port specific options.
8366 * _process_pragma: simplified since now we do not need *special*
8367 include file to define SFR registers. But a separate header
8368 will be needed. This will be developed later.
8369 * _pic16_parseOptions: added, parses port specific options:
8370 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8371 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8372 --preplace-udata-with=
8374 * _pic16_setDefaultOptions: modified to initialize section names,
8375 but hack is temporarly out of order since it needs improvement.
8376 * _pic16_genAssemblerPreamble: configuration words are emitted by
8377 their address instead of their name. This part is incomplete and
8378 supports only the 18Fxx2 devices. Other devices will emit an error
8379 during assembly since they do not contain the same set of config
8381 * _pic16_genIVT: is modified,
8383 * pcode.c: added definitions for some hardware registers that are needed
8385 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8386 All PCI entries are updated. Now LFSR is supported.
8387 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8388 * added pic16_newpCodeOpLit2 to support instructions with
8389 two literal arguments
8390 * pic16_pCode2str: corrected code that emits assembler instructions
8391 with two literal operands and those that have an access bit modifier
8392 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8393 this fixes a bug which caused some labels to be lost, when an
8394 assembler directive was added, i.e. banksel,
8395 * pic16_FixRegisterBanking: improved logic that causes the insertion
8397 * InlineFunction: functions that are called once, are not any more
8398 inlined. This can be a port option in the future,
8400 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8402 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8403 hold the corresponding uninitialized symbols,
8404 * pic16_allocProcessorRegister: registers have explicit marked the
8406 * pic16_allocInternalRegister: registers are explicit marked as
8408 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8409 processing list, so bit registers were lost,
8412 * ralloc.h: added field 'accessBank' and original symbol operand
8413 in register definition,
8414 * removed the field isMapped from register definition,
8416 ** Several functions have been removed from various sources:
8417 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8418 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8419 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8420 pic16_assignRelocatableRegisters
8422 ** others have been introduced:
8423 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8424 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8426 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8428 * support/scripts/inc2h.pl: changed definition of BIT_AT
8429 to emit 'sbit at' instead of 'bit at'. This was a request.
8431 PIC16 port related preliminary changes:
8432 * gen.c: prefixed function popRegFromString with
8433 pic16_ and all references to it corrected
8434 * pcode.c: all pic16_pc_* hardware registers prefixed
8435 with underscore (_),
8436 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8437 * ralloc.c: newReg(): when register is REG_SFR then
8438 set address to rIdx,
8439 pic16_allocProcessorRegister(): marks register wasUsed=0
8440 pic16_writeUsedRegs(): added a call to assign processor
8441 registers via pic16_assignFixedRegisters
8443 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8445 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8446 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8447 variables in unused register banks. Also the SSEG is placed
8448 wherever there is enough space for it, and IDATA can be anywhere
8449 in internal RAM. For now compile using -Wl-Y[stack_size].
8450 The mem file is different for this option as well, since it
8451 makes no sense of talking about DSEG lenght.
8453 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8455 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8456 in certain cases, e.g. when ROM assignment, patch provided
8457 from Albert den Haan.
8459 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

8698 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8700 * src/SDCCast.c (decorateType): disabled a transformation I added in
8701 revision 1.188 (access to fields of a structure at an absolute address);
8702 it breaks with bitfields, extern declarations, and gcse analysis.
8703 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8704 could be assigned through a pointer, so don't complain.
8705 * src/SDCCast.c (astErrors),
8707 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

9345 support for standard C idiom of memory mapped variables; for
9346 example, *((xdata int*)0x1234) = 1 is now internally equivalent
9347 to xdata int at 0x1234 tempvar = 1.
9348 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
9349 provided by Akiya ISHIDA

9365 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9367 Fixed bug #621531 (const & volatile confusion in the type chain).
9368 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively
9369 refer to the const or volatile state of the pointer itself.

9461 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9462 fetching of the pointer
9463 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9464 copied from genNearPointerSet()
9465 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9466 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9467 If they pop r0/r1 they must be called in the opposite order than aopOp().
9468 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"

9480 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9482 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9483 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9484 type for bits was changed. It resulted in bit variables becoming
9485 global, which is not permitted in PIC 14 assembly output.
9487 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9489 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9502 A few small changes that speed up the peephole optimizer.
9506 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9508 Try to make the peephole optimizer smarter by maintaining
9509 an association between the assembly source code and the
9510 iCodes that originated them. Put this information to use
9511 with a new peephole rule condition "notVolatile" so that
9512 the rules can be aggressive yet still safe.
9517 * src/mcs51/peeph.def
9519 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9523 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9524 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9525 if the left or right operand symbols have the accuse flag set.
9527 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9529 Changed the type of the result of the ! (NOT) operator to char;
9530 previously it returned the same type as the source. This allows
9531 us to eliminate all the genFloatNot functions (all of its target
9532 implementations were very buggy) since !float can use the same
9535 * src/SDCCicode.c (ast2iCode): ! returns char

9544 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9545 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9546 during interrupts. Ensure WSAVE is located at a shared bank address.
9547 2. Fixed page selection in some places
9548 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9549 the registers name strings.
9550 4. Fixed "signed / unsigned compare" compiler warnings.
9551 5. The PIC port manages its own allocation of the general purpose
9552 registers, but makes no attempt to reuse them. As a result when
9553 compiling it soon runs out of general purpose registers. Some
9554 additional code was added to the files pcode.c and device.c to walk
9555 through the function call tree and rename the registers so that they
9565 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9566 genPlus() & genMinus() when the result is the same as left or right

9572 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9574 Made bitfield a distinct type from bit so that bitfields
9575 convert as per ANSI C and bits retain their traditional
9576 boolean style behaviour. Implemented bitfield support in
9584 * src/ds390/gen.c: bit v bitfield split
9585 * src/z80/gen.c: New support for bitfields
9586 * support/regression/tests/bitfields.c: reenabled z80,
9589 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9591 Rules 246.x, 247.x relate to bitfields, the others speed up
9592 access to xdata mapped I/O devices.
9594 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9596 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9598 Cleaned up genPackBits and genUnpackBits and added two helper
9599 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9600 for literal assignments in genPackBits (thanks to Frieder for
9606 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9608 Fixed bug #748310 (pointer to function type mishandled when the
9609 function name is omitted). Also fixed a SIGSEGV when a function
9610 attribute (reentrant, etc) is used on a non-function or on a
9611 function but misplaced before the parameter list.
9613 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9615 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9616 * support/Util/SDCCerr.h,
9617 * support/Util/SDCCerr.c: Added func attr misuse error msg

9638 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9640 Made the constant following the "interrupt" keyword optional. If
9641 omitted, the function will not automatically be given an entry
9642 in the interrupt vector table (similar to #pragma NOIV, but
9643 less syntacticly kludgy). The interrupt number is also now
9644 range checked. Also fixed a bug in the high order bit example

9658 * src/SDCCicode.c (operandOperation): rewritten some ops
9659 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9660 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9662 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9663 be re-activated by defining REDUCE_LITERALS)
9664 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9665 unsigned, but are signed by default
9666 * src/SDCCval.c (constVal): rearranged
9667 * src/SDCCval.c (valMod): preliminary fix
9668 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9710 constants are unsigned; added recognition of "u" flag for unsigned
9711 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9712 * src/SDCCval.c (valDiv, valMod): fixed signdness
9713 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9714 signedness of modulo, left and right shift

10174 added if/endif conditional macros to remove options help
10175 messages from optionsTable when a port is not configured, added
10176 support for the PIc16 port in the ports table, when executing
10177 the compiler with no port specified on command line, a default
10178 port is selected with the new macro DEFAULT_PORT which is
10179 defined in port.h, in setDefaultOptions() linkOptions is removed
10180 from initialization assignment, since now it is a set,
10181 parseCmdLine uses setParseWithComma for linkOptions, in
10182 linkEdit() linkOptions are accessed with new function indexSet()
10183 which returns the i'th item of a set variable. See SDCCset.c, in
10184 linkEdit() when calling buildCmdLine(), added linkOptions as
10185 last argument. Now users can pass arguments to gplink via the
10186 -Wl option, main() uses pic16glue() to glue up pic16 programs

10200 gpasm complaining and test the linkage with gplink, _linkCmd and
10201 _asmCmd changed to be more gplink and gpasm friendly
10202 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10203 produced an error when parsed, peep rule 12 is added to utilize
10204 movff, but it is commented out since the pCode does not support
10205 yet a command with 2 address arguments
10207 2003-05-18 <johan AT balder>
10209 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11227 2003-01-07 <johan AT balder>
11229 * src/SDCCast.c (decorateType): fixed bug #600035
11231 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
11232 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
11233 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
11234 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
11235 * src/pic/pcode.c: outcommented unused variable to remove warnings

11242 2003-01-06 <johan AT balder>
11244 * src/SDCCicode.c: fixed array add
11246 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11247 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
11248 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
11250 2003-01-04 <johan AT balder>
11252 * src/SDCCval.c (getNelements): fixed the initialized array of structures
11254 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11255 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
11257 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11258 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
11259 * support/regression/tests/bug-524697.c: fit mem usage into 8032
11261 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11262 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11264 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11265 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11267 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11268 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11270 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11272 * in /sdcc/as/mcs51/ changed these files in order to create an
11273 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11274 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11275 following files to include the previous two files: aslink.dsp,
11276 Makefile.aslink, Makefile.bcc, and Makefile.in.
11278 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11279 .adb instead of .cdb
11281 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11283 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11284 value from option --iram-size.
11286 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11288 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11291 2002-09-18 <wiml AT hhhh.org>
11293 * SDCClrange.h: exposed setFromRange() and setToRange()
11294 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11295 packRegsForAccUse() (bug 542397)
11296 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11297 multiple times and emitting the fetch operations more than once
11298 added aopGetUsesAcc() function to allow binary operators to
11299 fetch their operands in the correct order; made genMinus() emit
11300 compact code for X = LITERAL - Y
11302 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11303 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11304 sprintf() in line 1267.
11306 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11307 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11310 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11311 Changes to aslink (All the changes are marked with 'JCF'):
11313 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11316 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11317 area BSEG. Also moves, if possible, the DATA area down into the internal
11318 ram so more space is available.
11320 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11323 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11324 not bytes. Function summary() which creates a memory usage summary
11325 file with extension .mem. Reports of overlaping stack and small stack
11326 size. If the space for the stack is less than 16 bytes aslink trows a
11329 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11330 the 8051. Option 'y' for memory summary output file.
11332 Changes to sdcc (All the changes are marked with 'JCF'):
11334 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11336 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11337 overlaying area for it (uses RegBankUsed[4]).
11339 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11340 bank zero as used by default. By default aslink locates the stack
11341 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11342 the creation of the .mem file. Delegates the allocation of data area
11343 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11344 the begining of the stack area to aslink.
11346 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11347 glue() in SDCCglue.c creates an area for it.
11349 2002-09-03 Borut Razem <borut.razem AT siol.net>
11350 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11351 sdcc/src/pic/glue.c:
11352 introduced atexit() handler for teporay files removal in case of
11353 errors, assertions, ...
11355 2002-08-29 Borut Razem <borut.razem AT siol.net>
11356 * sdcc/support/cpp2/auto-host_vc_in.h:
11357 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11358 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11359 Maybe there is a similar problem with BORLANDC? It should be checked!
11361 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11362 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11363 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11364 was not executed, and the compiler (cl) launched a warning:
11365 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11367 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11368 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11370 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11371 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11373 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11374 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11375 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11376 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11377 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11378 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11379 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11380 - added Release configuration in VS projects
11381 - review of compiler an linker options
11382 - VC .exe files are generated in bin_vc directory, not to interfere
11383 with binaries generated from other projects (cygwin, mingw, bcc ...)
11385 * sdcc/src/yacc.dsp: added
11387 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11388 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11389 and insert the version number definitions from .version
11391 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11393 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11394 added - genarate auto-host.h using auto-host_vc_in.h as template
11397 removed from CVS, generated automatically
11399 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11400 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11402 2002-08-11 Borut Razem <borut.razem AT siol.net>
11403 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11405 2002-08-10 Borut Razem <borut.razem AT siol.net>
11406 * src/SDCCmain.c (main):
11407 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11408 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11409 The consequence was that some temporary files were not removed.
11412 unification of code in functions tempfilename() and tempfile():
11413 function tempnam() is defined in Visual Studio 6.0 and .NET
11415 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11417 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11418 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11419 - removed compiler command line option /WX: Treats all warnings as errors
11420 - update a list of source files, included into the project
11422 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11423 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11424 changed project type to Generic Project so that can be correcly converted to VS.NET project
11426 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11428 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11430 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11432 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11433 added return 0 statements after assert() to make compiler happy
11435 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11436 added newline in the def file to keep MSC compiler satisfied
11438 * sdcc/src/z80/gen.c:
11439 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11440 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11441 - solved MSC error in function aopDump()
11443 * sdcc_vc.h: define PREFIX as "\\sdcc"
11445 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11446 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11449 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11450 - Rewrote the register banking algorithm.
11451 - Added pCode live-range analysis to registers (for now, only non-used and
11452 singly-used registers optimized away)
11454 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11456 * 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.

11473 * device/lib/z80/printf.c (sprintf): Added.
11475 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11477 * src/z80/peeph.def: Added transpose redundent load rule.
11479 * src/z80/main.c: Added force callee saves for jaune.
11481 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11483 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11485 2002-03-28 Johan Knol <johan AT balder>
11487 * src/SDCCval.c: fixed bug #532436
11489 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11491 Added "char *Processor" field to the port structure.
11494 Added -p option. Allows port dependent processor to be specified.
11497 Initialized the new field char *Processor field to NULL in all ports
11500 Compiler generated registers for interrupt context saving
11501 were not getting allocated.
11503 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11506 Fixed left shift. Will promote the left side of a left shift
11507 if a) left shifting more than size of operand or b) when assigned
11508 to something size > size of left side
11510 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11512 tons of changes. Register allocation has been
11513 rewritten. Added customization for the various PICs. Flow
11514 analysis is restructured. ...
11516 * src/pic/device.h:
11519 * src/pic/device.c:
11520 Added. device.c is a PIC port hack to accomodate variations
11523 2002-03-13 Michael Hope <michaelh AT vroom>
11525 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11527 2002-03-04 johanknol <johanknol AT manik>
11529 * /src/SDCCval.c: fixed
11531 const unsigned char arr[][2] = { { 0, 1 } };

11618 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11620 * sdcc/src/SDCCloop.c:
11621 Previous fix was not good. basic blocks that have "break" or "return" are
11622 not really partof a loop , but live ranges used in these blocks should
11623 be live thru the entire loop, so set partOfLoop but don't add them to
11626 2002-02-21 <johan AT FRIJA>
11628 * src/SDCCcse.c: fixed bug #514308
11630 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11633 Fixed BUG #519583. If a conditional block ended in a return/break
11634 statement inside a loop, it was not being considered part of the loop.
11636 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11638 2002-02-10 Karl Bongers <karl AT turbobit.com>

11649 for use as a multiple module SDCDB test case.
11651 * sim/ucsim/cmd.src/cmdset.cc:
11652 Took out debug printfs in ucsim "next" command.
11654 * sim/ucsim/xa.src:
11655 Karl and Johan start ucsim XA support. Most dissassembly working,
11656 about 75% emulation done(plenty of work remaining).
11658 * sim/ucsim/z80.src:
11659 Add Z80 support to ucsim, add test-ucz80 regression test,
11660 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
11661 Notice z80 compiler fails on examples/test3.c/crc code.
11663 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
11665 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:
11666 Added support for --parms-in-bank1
