1411 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1413 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1414 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1416 One basic decision: e.g. src/clean.mk includes further files. In order
1417 to make this work there are two solutions:
1418 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1419 run configure on them. This way they can use
1420 'include $(srcdir)/port-clean.mk'
1421 - always include clean.mk by the Makefile at the same level. To avoid
1422 that `make clean` tries to include and build Makefile.dep the
1423 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1424 implemented, because now even `make uninstall` doesn't create
1425 Makefile.in. clean.mk could be eliminated by pasting it in
1428 * debugger/mcs51/Makefile.in: build own objects from library sources
1429 (SLIB, SDCC) in current directory
1431 * configure, configure.in: renamed --disable-device-lib-build in
1432 --disable-device-lib; added --enable-doc, the required tools are
1433 searched by configure; added result message; the toolchain for the
1434 belonging ports are now only built, if the port is enabled.
1436 * support/regression/*: all output is written in directory gen, because
1437 the fwk and ports directories don't livet in the build tree using vpath
1439 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1440 --disable-device-lib, added --enable-doc, added section VPATH
1442 * sim/ucsim/configure.in,
1443 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1444 z80 are enabled by default
1446 2006-04-24 Raphael Neider <rneider AT web.de>
1448 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1449 to config word, "pic14_"-prefixed some extern functions
1450 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1451 config word has been found
1452 * src/pic/device.h: added prototypes
1453 * src/pic/pcode.c: added "pic14_"-prefix where needed

1470 fixes #1469504 and #1474602,
1471 (pCodeRegOptimizeRegUsage): fixed typo in comment

1744 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1745 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

1761 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1762 call to allocReg, not by manually allocating a new one,
1763 (pic16_assignRegisters): now before going through the register
1764 allocating functions mark all registers as free. This eliminates some
1765 side effects resulting from peephole parser done earlier in the backbone
1767 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1817 2006-03-06 Borut Razem <borut.razem AT siol.net>
1819 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1820 made the linker quiet
1822 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1824 * src/pic16/gen.c (genPcall): fixed bug #1443644
1825 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1826 which dumps before the function entry point a data byte which represents
1827 the number of the local variables used by the specified function, added
1828 'xinst' for initial support for Extended Instruction Support,
1829 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1830 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1831 port->fun_prefix anymore (may change later),

1844 --extended or -y for Extended Instruction Support,
1845 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1846 (deassignLRs): *** perhaps the most important change, old 'for' code
1847 (commented out for reference), didn't account for some registers which
1848 were left marked 'not free' after a pointer operation. The change
1849 reduces register usage a lot in some cases

4124 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4125 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4126 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4127 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4128 always available in leading double underscore form. The C99 support is
4129 mostly missing, but it's a start.
4130 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4131 reserved identifier "__data".
4133 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

4207 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4209 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4211 * device/lib/printf_large.c: removed inline assembly for portability and
4212 readability. Use printf_fast if speed or size are more important.
4213 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4214 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4216 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4218 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4219 prevent compiler warning
4221 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4223 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4224 moved to level 0 and declared as static. Also they are explicit
4225 placed in access bank. This was necessery because some times they
4226 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4227 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4228 optimizations. Currently only compare to unsigned char is implemented,
4229 * src/pic16/gen.c: added fReturnIdx array,
4230 * (struct resolvedIfx) is moved to gen.h and made public,
4231 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4232 * (aopForSym): added an optimization to directly store in stack of
4233 the operand of a SEND iCode,
4234 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4235 but as registers instead (AOP_REG) using the fReturnIdx array,
4236 * (pic16_freeAsmop): remove the freed register from the
4237 _G.sregsAlloc field,
4238 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4239 a compare of 'WREG',
4240 * (pic16_popGetTempRegCond): changed function prototype, now
4241 function takes also a bitVector argument v which holds the current
4242 set of registers that are allocated for stack access by aopForSym,
4243 registers allocated in aopForSym for accessing stack symbols are not
4244 any more part of the functions usedRegs field,
4245 * (genCall): some times aopOp is called for a stack variable to be
4246 send, aopForSym might perform the push, if this is true make sure
4247 that genCall doesn't push the variable twice by testing _G.resDirect,
4248 * (genFunction): changed testing for unspecified interrupt number
4249 from 256 to INTNO_UNSPEC,
4250 * modified selection scheme of frame pointer generation. Previously
4251 if function did use local registers a frame pointer was generated,
4252 now a frame pointer is generated only if function has arguments
4253 (that need PLUSW2 register access), or has stack arguments, or the
4254 compiler is not instructed to omit the frame pointer,
4255 * (genEndFunction): before restoring local registers that were saved
4256 in the function preamble, also restore the registers that *might*
4257 have been allocated for stack access,
4258 * (genRet): removed some old comments,
4259 * (genCmp, the active (RN's) version): added a call to the
4260 pic16_genCmp_special function to perform the compare with a more
4261 robust and optimized way,
4262 * (genInline): a feature has been added in inline code generation,
4263 which allows a wildcard variable substitution when writing inline
4264 assembly. Code is incomplete and experimental therefore undocumented,
4265 * (genCast): changed order of aopOp for result and right to allow
4266 aopForSym to directly load the result if possible,
4267 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4268 perform an optimized compare on some selected special occasions,
4269 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4270 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4271 generate an IVT any more,
4272 * src/pic16/main.c (pic16_optionsTable): added command line option
4274 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4275 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4277 * src/pic16/NOTES: Raphael Neider added in list of active developers
4278 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4279 jumptable_end to prevent bug #,
4280 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4281 inCond and outCond fields,
4282 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4283 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4284 turn off register spilling,
4285 * (packRegsForOneUse): synced with other ports' versions although it
4286 is not used currently,
4287 * (pic16_packRegisters): added an optimization while reading
4288 structure bitfields, some registers may be saved (malloc code is
4289 decreased by 80 bytes)
4291 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4293 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4294 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4295 this can be optimized more?
4297 2005-03-10 Raphael Neider <rneider AT web.de>
4299 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4300 genNearPointerGet): (hopefully) fixed access to bitfields via
4301 pointers (p->bitN = x; and x = p->bitN; failed)
4303 2005-03-09 Paul Stoffregen <paul AT pjrc.com>
4305 * device/lib/printf_fast.c: fix leading zero format, eg "%02d"
4307 2005-03-09 Raphael Neider <rneider AT web.de>
4309 * src/SDCCopt.c (killDeadCode): fixed bug #1156016
4311 2005-03-06 Maarten Brock <sourceforge.brock AT dse.nl>
4313 * src/SDCCicode.h: moved CRITICAL and ENDCRITICAL from SKIP_IC2 to SKIP_IC
4314 * src/mcs51/ralloc.c (willCauseSpill): added check for REG_BIT type,

4935 Adding support for replacing ljmps with sjmps in jumptables
4936 generated for switch statements. For now you need to set the
4937 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4938 Now 4 algorithms for mcs51 jumptable generation are used:
4939 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4940 addresses loaded pc-relative for up to 112 cases and stack-pushing
4941 target addresses loaded with offset from dptr for up to 256 cases.

4971 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4973 * added libc directory. The current version of LibC contains string
4974 functions, ctype functions and macros and some functions of the
4975 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4976 be extensively tested in the future. Standard disclaimer here.
4977 Library is not automatically build yet. But one can build it by
4978 invoking 'make' inside the libc directory.

4989 * (pic16_storeForReturn): optimized return of 0,
4990 * (genCmp): experimental code for new genCmp which uses PIC18's
4991 special compare&skip instructions. Initial tests fail some times
4992 with variables grater than 1 byte in size, so new code is disabled,
4993 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4995 * (genCast): began a fix to optimize the casting of a bit to another
4996 bit, now assigning a bitfield to another bitfield will fail, sorry,

5005 and 1 for banking instruction,
5006 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5007 caused stop processing pCodes after a inline assembly block,
5008 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5009 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5010 registers when it shouldn't,
5011 * src/pic16/ralloc.c (allocReg): add preliminary support for
5012 supporting a limited set of temporary registers,
5014 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5016 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,

5020 (genFunction): optimize RECEIVE iCodes in reentrant functions
5022 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5024 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8022 loaded with the linker search paths (-L arguments) and the libraries
8023 to be linked with the current source (-l arguments). Changes
8024 currently will affect only the pic16 port.
8025 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8026 include path the port specific paths and port specific libraries,
8027 * gplink command now contains the $3 argument,
8028 * src/pic16/device.h,
8029 * src/pic16/device.c,: structure PIC_device is made public and

8045 Documenting changes from previous commits.
8046 * configure.in (version 1.56),
8047 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8048 when generating output files to configure the pic16 library,
8049 but now I've commented it out, since gputils aren't installed in the
8050 SF compile farm, so library won't compile
8052 * device/lib/Makefile.in (version 1.56): initially I've added in
8053 target 'all' the prerequestive 'model-pic16' so it compiled the
8054 pic16 library, but now I've commented it out for the same reasons
8056 * added targets 'model-pic16' and 'objects-pic16' to compile the
8058 * added target 'port-specific-objects-pic16' to handle the
8059 generated libraries and copy them into the build/ directory
8060 * added target 'clean-intermediate-pic16' to clean intermediate
8061 files into pic16 directory
8062 * in target 'installdirs' added line to create directory pic16 in

8066 added lines to copy all header files to installation path,
8067 * in target 'installdirs' added line create directory for pic16
8068 headers in the installation path

8327 * src/SDCC.y (enum_specifier, enumerator_list, opt_assign_expr),
8328 * src/SDCCsymt.c (newEnumType),
8330 * support/Util/SDCCerr.c,
8331 * support/Util/SDCCerr.h: fixed bug #871258 and some other unreported
8333 * support/regression/tests/enum.c: added test for enum values that
8334 require at least 2 bytes of storage.
8336 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8338 * src/common.h: added ifndef/define/endif macros
8339 around the header file.
8340 Bug reported from Jesus Calvino-Fraga
8342 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8344 * sdcc.spec: updated
8345 * device/include/Makefile.in: don't install CVS directories
8346 * device/lib/Makefile.in: added removal of CVS directories after install
8347 * doc/Makefile: fixed install, added local_icons
8348 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8349 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8350 * src/ds390/gen.c (genRightShift): fixed bug #870788
8351 * src/SDCCast.c (decorateType): fixed bug #870781
8353 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8355 PIC16 port related changes:
8356 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8357 added variable stackPos,
8359 * gen.c: genCall, assignResultValue: added support for
8360 pushing/retrieving function parameters to/from stack,
8361 genFunction,genEndFunction: setup stack frame for the
8363 genAddrOf: will be changed according to bug 863624
8365 * added files genutils.c and genutils.h which contain gen*
8366 debugged and optimised functions extracted from gen.c
8368 * glue.c: added variable 'externs' which holds extern symbols,
8369 pic16emitRegularMap: is modified to properly handle relocatable
8370 symbols under the new scheme,
8371 pic16createInterruptVect: is modified
8372 pic16printPublics: is modified to emit 'global' assembler directives,
8373 added pic16_printExterns to print extern symbols,
8374 pic16glue: initializes stack/frame pointer in the beginning of
8375 the assembly output. Temporary hack, will be corrected later,
8376 because gplink yet does not support stack and SDCC does not
8377 yet support a type of crt0.o object to create the final binary.
8379 * Removed many lines that contain 8051 legacy code.
8380 * The code is finally placed under a 'code' directive.
8381 * Added port specific options.
8383 * _process_pragma: simplified since now we do not need *special*
8384 include file to define SFR registers. But a separate header
8385 will be needed. This will be developed later.
8386 * _pic16_parseOptions: added, parses port specific options:
8387 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8388 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8389 --preplace-udata-with=
8391 * _pic16_setDefaultOptions: modified to initialize section names,
8392 but hack is temporarly out of order since it needs improvement.
8393 * _pic16_genAssemblerPreamble: configuration words are emitted by
8394 their address instead of their name. This part is incomplete and
8395 supports only the 18Fxx2 devices. Other devices will emit an error
8396 during assembly since they do not contain the same set of config
8398 * _pic16_genIVT: is modified,
8400 * pcode.c: added definitions for some hardware registers that are needed
8402 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8403 All PCI entries are updated. Now LFSR is supported.
8404 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8405 * added pic16_newpCodeOpLit2 to support instructions with
8406 two literal arguments
8407 * pic16_pCode2str: corrected code that emits assembler instructions
8408 with two literal operands and those that have an access bit modifier
8409 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8410 this fixes a bug which caused some labels to be lost, when an
8411 assembler directive was added, i.e. banksel,
8412 * pic16_FixRegisterBanking: improved logic that causes the insertion
8414 * InlineFunction: functions that are called once, are not any more
8415 inlined. This can be a port option in the future,
8417 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8419 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8420 hold the corresponding uninitialized symbols,
8421 * pic16_allocProcessorRegister: registers have explicit marked the
8423 * pic16_allocInternalRegister: registers are explicit marked as
8425 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8426 processing list, so bit registers were lost,
8429 * ralloc.h: added field 'accessBank' and original symbol operand
8430 in register definition,
8431 * removed the field isMapped from register definition,
8433 ** Several functions have been removed from various sources:
8434 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8435 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8436 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8437 pic16_assignRelocatableRegisters
8439 ** others have been introduced:
8440 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8441 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8443 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8445 * support/scripts/inc2h.pl: changed definition of BIT_AT
8446 to emit 'sbit at' instead of 'bit at'. This was a request.
8448 PIC16 port related preliminary changes:
8449 * gen.c: prefixed function popRegFromString with
8450 pic16_ and all references to it corrected
8451 * pcode.c: all pic16_pc_* hardware registers prefixed
8452 with underscore (_),
8453 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8454 * ralloc.c: newReg(): when register is REG_SFR then
8455 set address to rIdx,
8456 pic16_allocProcessorRegister(): marks register wasUsed=0
8457 pic16_writeUsedRegs(): added a call to assign processor
8458 registers via pic16_assignFixedRegisters
8460 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8462 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8463 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8464 variables in unused register banks. Also the SSEG is placed
8465 wherever there is enough space for it, and IDATA can be anywhere
8466 in internal RAM. For now compile using -Wl-Y[stack_size].
8467 The mem file is different for this option as well, since it
8468 makes no sense of talking about DSEG lenght.
8470 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8472 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8473 in certain cases, e.g. when ROM assignment, patch provided
8474 from Albert den Haan.

8715 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8717 * src/SDCCast.c (decorateType): disabled a transformation I added in
8718 revision 1.188 (access to fields of a structure at an absolute address);
8719 it breaks with bitfields, extern declarations, and gcse analysis.
8720 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8721 could be assigned through a pointer, so don't complain.
8722 * src/SDCCast.c (astErrors),
8724 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

9362 support for standard C idiom of memory mapped variables; for
9363 example, *((xdata int*)0x1234) = 1 is now internally equivalent
9364 to xdata int at 0x1234 tempvar = 1.
9365 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
9366 provided by Akiya ISHIDA

9478 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9479 fetching of the pointer
9480 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9481 copied from genNearPointerSet()
9482 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9483 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9497 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9499 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9500 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9501 type for bits was changed. It resulted in bit variables becoming
9502 global, which is not permitted in PIC 14 assembly output.
9504 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9506 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9519 A few small changes that speed up the peephole optimizer.
9523 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9525 Try to make the peephole optimizer smarter by maintaining
9526 an association between the assembly source code and the
9527 iCodes that originated them. Put this information to use
9528 with a new peephole rule condition "notVolatile" so that
9529 the rules can be aggressive yet still safe.
9534 * src/mcs51/peeph.def
9536 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9540 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9541 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9542 if the left or right operand symbols have the accuse flag set.
9544 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9546 Changed the type of the result of the ! (NOT) operator to char;
9547 previously it returned the same type as the source. This allows
9548 us to eliminate all the genFloatNot functions (all of its target
9549 implementations were very buggy) since !float can use the same
9552 * src/SDCCicode.c (ast2iCode): ! returns char

9561 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9562 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9563 during interrupts. Ensure WSAVE is located at a shared bank address.
9564 2. Fixed page selection in some places
9565 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9566 the registers name strings.
9567 4. Fixed "signed / unsigned compare" compiler warnings.
9568 5. The PIC port manages its own allocation of the general purpose
9569 registers, but makes no attempt to reuse them. As a result when
9570 compiling it soon runs out of general purpose registers. Some
9571 additional code was added to the files pcode.c and device.c to walk
9572 through the function call tree and rename the registers so that they
9582 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9583 genPlus() & genMinus() when the result is the same as left or right
9585 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9589 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9591 Made bitfield a distinct type from bit so that bitfields
9592 convert as per ANSI C and bits retain their traditional
9593 boolean style behaviour. Implemented bitfield support in
9601 * src/ds390/gen.c: bit v bitfield split
9602 * src/z80/gen.c: New support for bitfields
9603 * support/regression/tests/bitfields.c: reenabled z80,
9606 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9608 Rules 246.x, 247.x relate to bitfields, the others speed up
9609 access to xdata mapped I/O devices.
9611 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9613 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9615 Cleaned up genPackBits and genUnpackBits and added two helper
9616 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9617 for literal assignments in genPackBits (thanks to Frieder for
9623 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9625 Fixed bug #748310 (pointer to function type mishandled when the
9626 function name is omitted). Also fixed a SIGSEGV when a function
9627 attribute (reentrant, etc) is used on a non-function or on a
9628 function but misplaced before the parameter list.
9630 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9632 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9633 * support/Util/SDCCerr.h,
9634 * support/Util/SDCCerr.c: Added func attr misuse error msg

9655 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9657 Made the constant following the "interrupt" keyword optional. If
9658 omitted, the function will not automatically be given an entry
9659 in the interrupt vector table (similar to #pragma NOIV, but
9660 less syntacticly kludgy). The interrupt number is also now
9661 range checked. Also fixed a bug in the high order bit example

9675 * src/SDCCicode.c (operandOperation): rewritten some ops
9676 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9677 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9679 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9680 be re-activated by defining REDUCE_LITERALS)
9681 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9682 unsigned, but are signed by default
9683 * src/SDCCval.c (constVal): rearranged
9684 * src/SDCCval.c (valMod): preliminary fix
9685 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10192 messages from optionsTable when a port is not configured, added
10193 support for the PIc16 port in the ports table, when executing
10194 the compiler with no port specified on command line, a default
10195 port is selected with the new macro DEFAULT_PORT which is
10196 defined in port.h, in setDefaultOptions() linkOptions is removed
10197 from initialization assignment, since now it is a set,
10198 parseCmdLine uses setParseWithComma for linkOptions, in
10199 linkEdit() linkOptions are accessed with new function indexSet()
10200 which returns the i'th item of a set variable. See SDCCset.c, in
10201 linkEdit() when calling buildCmdLine(), added linkOptions as
10202 last argument. Now users can pass arguments to gplink via the
10203 -Wl option, main() uses pic16glue() to glue up pic16 programs

10217 gpasm complaining and test the linkage with gplink, _linkCmd and
10218 _asmCmd changed to be more gplink and gpasm friendly
10219 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10220 produced an error when parsed, peep rule 12 is added to utilize
10221 movff, but it is commented out since the pCode does not support
10222 yet a command with 2 address arguments

11248 2003-01-07 Bernhard Held <bernhard AT bernhardheld.de>
11249 * as/mcs51/lkmem.c: added several l-modifiers to printf to remove warnings
11250 * as/mcs51/lkaomf51.c: #include <ctype.h> to remove warnings
11251 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings

11259 2003-01-06 <johan AT balder>
11261 * src/SDCCicode.c: fixed array add
11263 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11264 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
11265 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
11267 2003-01-04 <johan AT balder>
11269 * src/SDCCval.c (getNelements): fixed the initialized array of structures
11271 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11272 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
11274 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11275 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
11276 * support/regression/tests/bug-524697.c: fit mem usage into 8032
11278 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11279 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11281 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11282 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11284 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11285 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11287 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11289 * in /sdcc/as/mcs51/ changed these files in order to create an
11290 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11291 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11292 following files to include the previous two files: aslink.dsp,
11293 Makefile.aslink, Makefile.bcc, and Makefile.in.
11295 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11296 .adb instead of .cdb
11298 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11300 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11301 value from option --iram-size.
11303 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11305 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11308 2002-09-18 <wiml AT hhhh.org>
11310 * SDCClrange.h: exposed setFromRange() and setToRange()
11311 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11312 packRegsForAccUse() (bug 542397)
11313 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11314 multiple times and emitting the fetch operations more than once
11315 added aopGetUsesAcc() function to allow binary operators to
11316 fetch their operands in the correct order; made genMinus() emit
11317 compact code for X = LITERAL - Y
11319 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11320 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11321 sprintf() in line 1267.
11323 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11324 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11327 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11328 Changes to aslink (All the changes are marked with 'JCF'):
11330 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11333 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11334 area BSEG. Also moves, if possible, the DATA area down into the internal
11335 ram so more space is available.
11337 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11340 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11341 not bytes. Function summary() which creates a memory usage summary
11342 file with extension .mem. Reports of overlaping stack and small stack
11343 size. If the space for the stack is less than 16 bytes aslink trows a
11346 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11347 the 8051. Option 'y' for memory summary output file.
11349 Changes to sdcc (All the changes are marked with 'JCF'):
11351 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11353 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11354 overlaying area for it (uses RegBankUsed[4]).
11356 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11357 bank zero as used by default. By default aslink locates the stack
11358 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11359 the creation of the .mem file. Delegates the allocation of data area
11360 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11361 the begining of the stack area to aslink.
11363 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11364 glue() in SDCCglue.c creates an area for it.
11366 2002-09-03 Borut Razem <borut.razem AT siol.net>
11367 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11368 sdcc/src/pic/glue.c:
11369 introduced atexit() handler for teporay files removal in case of
11370 errors, assertions, ...
11372 2002-08-29 Borut Razem <borut.razem AT siol.net>
11373 * sdcc/support/cpp2/auto-host_vc_in.h:
11374 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11375 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11376 Maybe there is a similar problem with BORLANDC? It should be checked!
11378 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11379 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11380 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11381 was not executed, and the compiler (cl) launched a warning:
11382 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11384 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11385 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11387 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11388 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11390 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11391 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11392 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11393 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11394 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11395 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11396 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11397 - added Release configuration in VS projects
11398 - review of compiler an linker options
11399 - VC .exe files are generated in bin_vc directory, not to interfere
11400 with binaries generated from other projects (cygwin, mingw, bcc ...)
11402 * sdcc/src/yacc.dsp: added
11404 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11405 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11406 and insert the version number definitions from .version
11408 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11410 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11411 added - genarate auto-host.h using auto-host_vc_in.h as template
11414 removed from CVS, generated automatically
11416 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11417 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11419 2002-08-11 Borut Razem <borut.razem AT siol.net>
11420 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11422 2002-08-10 Borut Razem <borut.razem AT siol.net>
11423 * src/SDCCmain.c (main):
11424 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11425 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11426 The consequence was that some temporary files were not removed.
11429 unification of code in functions tempfilename() and tempfile():
11430 function tempnam() is defined in Visual Studio 6.0 and .NET
11432 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11434 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11435 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11436 - removed compiler command line option /WX: Treats all warnings as errors
11437 - update a list of source files, included into the project
11439 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11440 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11441 changed project type to Generic Project so that can be correcly converted to VS.NET project
11443 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11445 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11447 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11449 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11450 added return 0 statements after assert() to make compiler happy
11452 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11453 added newline in the def file to keep MSC compiler satisfied
11455 * sdcc/src/z80/gen.c:
11456 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11457 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11458 - solved MSC error in function aopDump()
11460 * sdcc_vc.h: define PREFIX as "\\sdcc"
11462 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11463 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11465 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11466 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11467 - Rewrote the register banking algorithm.
11468 - Added pCode live-range analysis to registers (for now, only non-used and
11469 singly-used registers optimized away)
11471 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11473 * 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.
11475 2002-05-10 Scott Dattalo <scott AT dattalo.com>

11488 2002-04-15 Michael Hope <michaelh AT vroom>
11490 * device/lib/z80/printf.c (sprintf): Added.
11492 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11494 * src/z80/peeph.def: Added transpose redundent load rule.
11496 * src/z80/main.c: Added force callee saves for jaune.
11498 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11500 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11502 2002-03-28 Johan Knol <johan AT balder>
11504 * src/SDCCval.c: fixed bug #532436
11506 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11508 Added "char *Processor" field to the port structure.
11511 Added -p option. Allows port dependent processor to be specified.
11514 Initialized the new field char *Processor field to NULL in all ports
11517 Compiler generated registers for interrupt context saving
11518 were not getting allocated.
11520 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11523 Fixed left shift. Will promote the left side of a left shift
11524 if a) left shifting more than size of operand or b) when assigned
11525 to something size > size of left side
11527 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11529 tons of changes. Register allocation has been
11530 rewritten. Added customization for the various PICs. Flow
11531 analysis is restructured. ...
11533 * src/pic/device.h:
11536 * src/pic/device.c:
11537 Added. device.c is a PIC port hack to accomodate variations
11540 2002-03-13 Michael Hope <michaelh AT vroom>
11542 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11544 2002-03-04 johanknol <johanknol AT manik>
11546 * /src/SDCCval.c: fixed
11548 const unsigned char arr[][2] = { { 0, 1 } };

11609 2002-03-01 <johan AT FRIJA>
11611 * src/SDCCglue.c (printIvalPtr): fixed bug #524211
11613 * src/SDCCast.c (decorateType): fixed bug #524209

11635 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11637 * sdcc/src/SDCCloop.c:
11638 Previous fix was not good. basic blocks that have "break" or "return" are
11639 not really partof a loop , but live ranges used in these blocks should
11640 be live thru the entire loop, so set partOfLoop but don't add them to
11643 2002-02-21 <johan AT FRIJA>
11645 * src/SDCCcse.c: fixed bug #514308
11647 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11650 Fixed BUG #519583. If a conditional block ended in a return/break
11651 statement inside a loop, it was not being considered part of the loop.
11653 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11655 2002-02-10 Karl Bongers <karl AT turbobit.com>
