1361 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1363 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1364 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1366 One basic decision: e.g. src/clean.mk includes further files. In order
1367 to make this work there are two solutions:
1368 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1369 run configure on them. This way they can use
1370 'include $(srcdir)/port-clean.mk'
1371 - always include clean.mk by the Makefile at the same level. To avoid
1372 that `make clean` tries to include and build Makefile.dep the
1373 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1374 implemented, because now even `make uninstall` doesn't create
1375 Makefile.in. clean.mk could be eliminated by pasting it in
1378 * debugger/mcs51/Makefile.in: build own objects from library sources
1379 (SLIB, SDCC) in current directory
1381 * configure, configure.in: renamed --disable-device-lib-build in
1382 --disable-device-lib; added --enable-doc, the required tools are
1383 searched by configure; added result message; the toolchain for the
1384 belonging ports are now only built, if the port is enabled.
1386 * support/regression/*: all output is written in directory gen, because
1387 the fwk and ports directories don't livet in the build tree using vpath
1389 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1390 --disable-device-lib, added --enable-doc, added section VPATH
1392 * sim/ucsim/configure.in,
1393 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1394 z80 are enabled by default
1396 2006-04-24 Raphael Neider <rneider AT web.de>
1398 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1399 to config word, "pic14_"-prefixed some extern functions
1400 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1401 config word has been found
1402 * src/pic/device.h: added prototypes

1712 call to allocReg, not by manually allocating a new one,
1713 (pic16_assignRegisters): now before going through the register
1714 allocating functions mark all registers as free. This eliminates some
1715 side effects resulting from peephole parser done earlier in the backbone

1782 (genFunction, genEndFunction): do not store/restore local registers for
1783 _main (this should take care the --main-return command line option in
1785 (genOr): removed some legacy pic-port instructions,
1786 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1787 performing operations with SFR's causes data to be written more than
1788 once to each SFR. Perhaps SFRs should be handled in special cases...
1789 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1791 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1792 into account for stack starting position,

1794 --extended or -y for Extended Instruction Support,
1795 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1796 (deassignLRs): *** perhaps the most important change, old 'for' code
1797 (commented out for reference), didn't account for some registers which
1798 were left marked 'not free' after a pointer operation. The change
1799 reduces register usage a lot in some cases

4072 * src/SDCCglobal.h (struct options),
4074 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4075 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4076 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4077 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4078 always available in leading double underscore form. The C99 support is
4079 mostly missing, but it's a start.
4080 * support/regression/tests/bug-227710.c: fixed nonconforming use of

4159 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4161 * device/lib/printf_large.c: removed inline assembly for portability and
4162 readability. Use printf_fast if speed or size are more important.
4163 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4164 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4166 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4168 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4169 prevent compiler warning
4171 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4173 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4174 moved to level 0 and declared as static. Also they are explicit
4175 placed in access bank. This was necessery because some times they
4176 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4177 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4178 optimizations. Currently only compare to unsigned char is implemented,
4179 * src/pic16/gen.c: added fReturnIdx array,
4180 * (struct resolvedIfx) is moved to gen.h and made public,
4181 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4182 * (aopForSym): added an optimization to directly store in stack of
4183 the operand of a SEND iCode,
4184 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4185 but as registers instead (AOP_REG) using the fReturnIdx array,
4186 * (pic16_freeAsmop): remove the freed register from the
4187 _G.sregsAlloc field,
4188 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4189 a compare of 'WREG',
4190 * (pic16_popGetTempRegCond): changed function prototype, now
4191 function takes also a bitVector argument v which holds the current
4192 set of registers that are allocated for stack access by aopForSym,
4193 registers allocated in aopForSym for accessing stack symbols are not
4194 any more part of the functions usedRegs field,
4195 * (genCall): some times aopOp is called for a stack variable to be
4196 send, aopForSym might perform the push, if this is true make sure
4197 that genCall doesn't push the variable twice by testing _G.resDirect,
4198 * (genFunction): changed testing for unspecified interrupt number
4199 from 256 to INTNO_UNSPEC,
4200 * modified selection scheme of frame pointer generation. Previously
4201 if function did use local registers a frame pointer was generated,
4202 now a frame pointer is generated only if function has arguments
4203 (that need PLUSW2 register access), or has stack arguments, or the
4204 compiler is not instructed to omit the frame pointer,
4205 * (genEndFunction): before restoring local registers that were saved
4206 in the function preamble, also restore the registers that *might*
4207 have been allocated for stack access,
4208 * (genRet): removed some old comments,
4209 * (genCmp, the active (RN's) version): added a call to the
4210 pic16_genCmp_special function to perform the compare with a more
4211 robust and optimized way,
4212 * (genInline): a feature has been added in inline code generation,
4213 which allows a wildcard variable substitution when writing inline
4214 assembly. Code is incomplete and experimental therefore undocumented,
4215 * (genCast): changed order of aopOp for result and right to allow
4216 aopForSym to directly load the result if possible,
4217 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4218 perform an optimized compare on some selected special occasions,
4219 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4220 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4221 generate an IVT any more,
4222 * src/pic16/main.c (pic16_optionsTable): added command line option
4224 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4225 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4227 * src/pic16/NOTES: Raphael Neider added in list of active developers
4228 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4229 jumptable_end to prevent bug #,
4230 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4231 inCond and outCond fields,
4232 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4233 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4234 turn off register spilling,
4235 * (packRegsForOneUse): synced with other ports' versions although it
4236 is not used currently,
4237 * (pic16_packRegisters): added an optimization while reading
4238 structure bitfields, some registers may be saved (malloc code is
4239 decreased by 80 bytes)
4241 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4243 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4244 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4245 this can be optimized more?
4247 2005-03-10 Raphael Neider <rneider AT web.de>
4249 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4250 genNearPointerGet): (hopefully) fixed access to bitfields via
4251 pointers (p->bitN = x; and x = p->bitN; failed)
4253 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4296 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4297 to keep the correct label reference count when adding/removing references
4298 to labels. A peephole file using this is appended to patch #1144962.
4300 2005-02-14 Raphael Neider <rneider AT web.de>

4885 Adding support for replacing ljmps with sjmps in jumptables
4886 generated for switch statements. For now you need to set the
4887 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4888 Now 4 algorithms for mcs51 jumptable generation are used:
4889 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4890 addresses loaded pc-relative for up to 112 cases and stack-pushing
4891 target addresses loaded with offset from dptr for up to 256 cases.

4921 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4923 * added libc directory. The current version of LibC contains string
4924 functions, ctype functions and macros and some functions of the
4925 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4926 be extensively tested in the future. Standard disclaimer here.
4927 Library is not automatically build yet. But one can build it by
4928 invoking 'make' inside the libc directory.

4939 * (pic16_storeForReturn): optimized return of 0,
4940 * (genCmp): experimental code for new genCmp which uses PIC18's
4941 special compare&skip instructions. Initial tests fail some times
4942 with variables grater than 1 byte in size, so new code is disabled,
4943 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4945 * (genCast): began a fix to optimize the casting of a bit to another
4946 bit, now assigning a bitfield to another bitfield will fail, sorry,

4955 and 1 for banking instruction,
4956 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
4957 caused stop processing pCodes after a inline assembly block,
4958 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4960 registers when it shouldn't,
4961 * src/pic16/ralloc.c (allocReg): add preliminary support for
4962 supporting a limited set of temporary registers,
4964 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4970 (genFunction): optimize RECEIVE iCodes in reentrant functions
4972 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7855 virus/worm forged address usage.
7857 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
7859 Fixed promotion, it should be done on AST level:

7883 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
7885 * src/SDCCast.c: added an additional type flow in decorateType() of
7886 opposite direction, see feature request #860006; it's enabled at runtime
7887 by setting the environment variable SDCC_NEWTYPEFLOW
7888 * src/SDCCast.h: changed prototype of decorateType()
7889 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
7890 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
7891 'char' to 'int' can be omitted, if both operands are 'unsigned char';
7892 see feature request #877103
7893 * src/SDCCval.c: updated call of decorateType()
7894 (valBitwise): fixed bug #882876

7922 added support for multiple code pages and multiple RAM banks on the
7923 PIC 14 port. The ASM files now no longer simply assume all the
7924 code / RAM are in the same page / bank. This means the linker can
7925 safely allocate code/RAM of separate ASM files to different pages/banks.
7926 * doc/sdccman.lyx: added Slade's tips
7927 * src/mcs51/peeph.def: fixed bug #880768

7969 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7971 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7972 loaded with the linker search paths (-L arguments) and the libraries
7973 to be linked with the current source (-l arguments). Changes
7974 currently will affect only the pic16 port.
7975 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7976 include path the port specific paths and port specific libraries,
7977 * gplink command now contains the $3 argument,
7978 * src/pic16/device.h,
7979 * src/pic16/device.c,: structure PIC_device is made public and
7980 renamed to PIC16_device, the same for variable Pics which is renamed

7995 Documenting changes from previous commits.
7996 * configure.in (version 1.56),
7997 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7998 when generating output files to configure the pic16 library,
7999 but now I've commented it out, since gputils aren't installed in the
8000 SF compile farm, so library won't compile
8002 * device/lib/Makefile.in (version 1.56): initially I've added in
8003 target 'all' the prerequestive 'model-pic16' so it compiled the
8004 pic16 library, but now I've commented it out for the same reasons
8006 * added targets 'model-pic16' and 'objects-pic16' to compile the
8008 * added target 'port-specific-objects-pic16' to handle the
8009 generated libraries and copy them into the build/ directory
8010 * added target 'clean-intermediate-pic16' to clean intermediate
8011 files into pic16 directory
8012 * in target 'installdirs' added line to create directory pic16 in
8013 the installation path
8015 * device/include/Makefile.in (version 1.11): in target 'install'
8016 added lines to copy all header files to installation path,
8017 * in target 'installdirs' added line create directory for pic16
8018 headers in the installation path

8033 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8034 option so that it actually works. Made it specific to the z80, since
8035 the gbz80 doesn't have these kinds of I/O ports.
8037 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8039 * device/include/z180.h,

8063 via literal number. The symbol is placed in the corresponding
8064 position of the data ram
8065 * (pic16_dump_section): relocatable and absolute uninitialized
8066 data are now emitted in sorted order to reduce section naming,
8067 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8068 weren't marked as being in the access bank,
8070 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8072 Added portion of GNU PIC Library under the directory
8073 device/include/pic16 and device/lib/pic16. These files
8074 contain the declarations of SFRs for the PIC18Fxx2 devices.
8075 The directory is initialized via configure from toplevel.

8105 all over. Telling LaTeX to be less strict with word spacing
8106 to better keep the right margin. Changed some notes about
8107 maintainance of the ports in section 3.2.1 - is it OK like this?

8303 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8305 PIC16 port related changes:
8306 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8307 added variable stackPos,
8309 * gen.c: genCall, assignResultValue: added support for
8310 pushing/retrieving function parameters to/from stack,
8311 genFunction,genEndFunction: setup stack frame for the
8313 genAddrOf: will be changed according to bug 863624
8315 * added files genutils.c and genutils.h which contain gen*
8316 debugged and optimised functions extracted from gen.c
8318 * glue.c: added variable 'externs' which holds extern symbols,
8319 pic16emitRegularMap: is modified to properly handle relocatable
8320 symbols under the new scheme,
8321 pic16createInterruptVect: is modified
8322 pic16printPublics: is modified to emit 'global' assembler directives,
8323 added pic16_printExterns to print extern symbols,
8324 pic16glue: initializes stack/frame pointer in the beginning of
8325 the assembly output. Temporary hack, will be corrected later,
8326 because gplink yet does not support stack and SDCC does not
8327 yet support a type of crt0.o object to create the final binary.
8329 * Removed many lines that contain 8051 legacy code.
8330 * The code is finally placed under a 'code' directive.
8331 * Added port specific options.
8333 * _process_pragma: simplified since now we do not need *special*
8334 include file to define SFR registers. But a separate header
8335 will be needed. This will be developed later.
8336 * _pic16_parseOptions: added, parses port specific options:
8337 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8338 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8339 --preplace-udata-with=
8341 * _pic16_setDefaultOptions: modified to initialize section names,
8342 but hack is temporarly out of order since it needs improvement.
8343 * _pic16_genAssemblerPreamble: configuration words are emitted by
8344 their address instead of their name. This part is incomplete and
8345 supports only the 18Fxx2 devices. Other devices will emit an error
8346 during assembly since they do not contain the same set of config
8348 * _pic16_genIVT: is modified,
8350 * pcode.c: added definitions for some hardware registers that are needed
8352 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8353 All PCI entries are updated. Now LFSR is supported.
8354 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8355 * added pic16_newpCodeOpLit2 to support instructions with
8356 two literal arguments
8357 * pic16_pCode2str: corrected code that emits assembler instructions
8358 with two literal operands and those that have an access bit modifier
8359 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8360 this fixes a bug which caused some labels to be lost, when an
8361 assembler directive was added, i.e. banksel,
8362 * pic16_FixRegisterBanking: improved logic that causes the insertion
8364 * InlineFunction: functions that are called once, are not any more
8365 inlined. This can be a port option in the future,
8367 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8369 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8370 hold the corresponding uninitialized symbols,
8371 * pic16_allocProcessorRegister: registers have explicit marked the
8373 * pic16_allocInternalRegister: registers are explicit marked as
8375 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8376 processing list, so bit registers were lost,
8379 * ralloc.h: added field 'accessBank' and original symbol operand
8380 in register definition,
8381 * removed the field isMapped from register definition,
8383 ** Several functions have been removed from various sources:
8384 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8385 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8386 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8387 pic16_assignRelocatableRegisters
8389 ** others have been introduced:
8390 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8391 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8393 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8395 * support/scripts/inc2h.pl: changed definition of BIT_AT
8396 to emit 'sbit at' instead of 'bit at'. This was a request.
8398 PIC16 port related preliminary changes:
8399 * gen.c: prefixed function popRegFromString with
8400 pic16_ and all references to it corrected
8401 * pcode.c: all pic16_pc_* hardware registers prefixed
8402 with underscore (_),
8403 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8404 * ralloc.c: newReg(): when register is REG_SFR then
8405 set address to rIdx,
8406 pic16_allocProcessorRegister(): marks register wasUsed=0
8407 pic16_writeUsedRegs(): added a call to assign processor
8408 registers via pic16_assignFixedRegisters
8410 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8412 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8413 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8414 variables in unused register banks. Also the SSEG is placed
8415 wherever there is enough space for it, and IDATA can be anywhere
8416 in internal RAM. For now compile using -Wl-Y[stack_size].
8417 The mem file is different for this option as well, since it
8418 makes no sense of talking about DSEG lenght.
8420 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8422 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8423 in certain cases, e.g. when ROM assignment, patch provided
8424 from Albert den Haan.

8665 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8667 * src/SDCCast.c (decorateType): disabled a transformation I added in
8668 revision 1.188 (access to fields of a structure at an absolute address);
8669 it breaks with bitfields, extern declarations, and gcse analysis.
8670 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8671 could be assigned through a pointer, so don't complain.
8672 * src/SDCCast.c (astErrors),

8776 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
8777 uninitialized variables) for the mcs51. Set environment variable
8778 SDCC_GENRAMCLEAR to test.
8779 xdata initialization slightly shorter
8781 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9431 copied from genNearPointerSet()
9432 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9433 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9449 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9450 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9451 type for bits was changed. It resulted in bit variables becoming
9452 global, which is not permitted in PIC 14 assembly output.
9454 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9456 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9469 A few small changes that speed up the peephole optimizer.
9473 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9475 Try to make the peephole optimizer smarter by maintaining
9476 an association between the assembly source code and the
9477 iCodes that originated them. Put this information to use
9478 with a new peephole rule condition "notVolatile" so that
9479 the rules can be aggressive yet still safe.
9484 * src/mcs51/peeph.def
9486 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9490 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9491 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9492 if the left or right operand symbols have the accuse flag set.
9494 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9496 Changed the type of the result of the ! (NOT) operator to char;
9497 previously it returned the same type as the source. This allows
9498 us to eliminate all the genFloatNot functions (all of its target
9499 implementations were very buggy) since !float can use the same
9502 * src/SDCCicode.c (ast2iCode): ! returns char

9511 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9512 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9513 during interrupts. Ensure WSAVE is located at a shared bank address.
9514 2. Fixed page selection in some places
9515 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9516 the registers name strings.
9517 4. Fixed "signed / unsigned compare" compiler warnings.
9518 5. The PIC port manages its own allocation of the general purpose
9519 registers, but makes no attempt to reuse them. As a result when
9520 compiling it soon runs out of general purpose registers. Some
9521 additional code was added to the files pcode.c and device.c to walk
9522 through the function call tree and rename the registers so that they
9532 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9533 genPlus() & genMinus() when the result is the same as left or right

9539 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9541 Made bitfield a distinct type from bit so that bitfields
9542 convert as per ANSI C and bits retain their traditional
9543 boolean style behaviour. Implemented bitfield support in
9551 * src/ds390/gen.c: bit v bitfield split
9552 * src/z80/gen.c: New support for bitfields
9553 * support/regression/tests/bitfields.c: reenabled z80,
9556 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9558 Rules 246.x, 247.x relate to bitfields, the others speed up
9559 access to xdata mapped I/O devices.
9561 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9563 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9565 Cleaned up genPackBits and genUnpackBits and added two helper
9566 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9567 for literal assignments in genPackBits (thanks to Frieder for
9573 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9575 Fixed bug #748310 (pointer to function type mishandled when the
9576 function name is omitted). Also fixed a SIGSEGV when a function
9577 attribute (reentrant, etc) is used on a non-function or on a
9578 function but misplaced before the parameter list.
9580 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9582 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9583 * support/Util/SDCCerr.h,

9605 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9607 Made the constant following the "interrupt" keyword optional. If
9608 omitted, the function will not automatically be given an entry
9609 in the interrupt vector table (similar to #pragma NOIV, but
9610 less syntacticly kludgy). The interrupt number is also now
9611 range checked. Also fixed a bug in the high order bit example

9619 * support/Util/SDCCerr.h
9622 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9624 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
9625 * src/SDCCicode.c (operandOperation): rewritten some ops
9626 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9627 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9629 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9630 be re-activated by defining REDUCE_LITERALS)
9631 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9632 unsigned, but are signed by default
9633 * src/SDCCval.c (constVal): rearranged
9634 * src/SDCCval.c (valMod): preliminary fix
9635 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9677 constants are unsigned; added recognition of "u" flag for unsigned
9678 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9679 * src/SDCCval.c (valDiv, valMod): fixed signdness
9680 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9681 signedness of modulo, left and right shift

10088 the regression tests I'm not brave enough to enable 245.b, 245.c
10089 * doc/sdccman.lyx: added latex preamble for hyperref package.
10090 Using pdflatex this will give you a hyperlinked pdf file with

10141 added if/endif conditional macros to remove options help
10142 messages from optionsTable when a port is not configured, added
10143 support for the PIc16 port in the ports table, when executing
10144 the compiler with no port specified on command line, a default
10145 port is selected with the new macro DEFAULT_PORT which is
10146 defined in port.h, in setDefaultOptions() linkOptions is removed
10147 from initialization assignment, since now it is a set,
10148 parseCmdLine uses setParseWithComma for linkOptions, in
10149 linkEdit() linkOptions are accessed with new function indexSet()
10150 which returns the i'th item of a set variable. See SDCCset.c, in
10151 linkEdit() when calling buildCmdLine(), added linkOptions as
10152 last argument. Now users can pass arguments to gplink via the
10153 -Wl option, main() uses pic16glue() to glue up pic16 programs

10166 * src/pic16/main.c: __config directives are commented out to stop
10167 gpasm complaining and test the linkage with gplink, _linkCmd and
10168 _asmCmd changed to be more gplink and gpasm friendly
10169 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10170 produced an error when parsed, peep rule 12 is added to utilize
10171 movff, but it is commented out since the pCode does not support
10172 yet a command with 2 address arguments
10174 2003-05-18 <johan AT balder>
10176 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11201 * src/pic/main.c (_hasNativeMulFor): outcommented unused variables to remove warnings
11202 * src/pic/pcode.c: outcommented unused variable to remove warnings
11203 * src/pic/ralloc.c: outcommented unused variable to remove warnings
11205 2003-01-06 <karl AT turbobit.com>
11206 * sim/ucsim/cmd.src/command.cc: fixed so "break xram r 0x7654" works again in
11209 2003-01-06 <johan AT balder>
11211 * src/SDCCicode.c: fixed array add
11213 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11214 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests
11215 * support/regression/ports/host/support.c: #include <stdarg.h> for gcc 3.2
11217 2003-01-04 <johan AT balder>
11219 * src/SDCCval.c (getNelements): fixed the initialized array of structures
11221 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11222 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
11224 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11225 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
11226 * support/regression/tests/bug-524697.c: fit mem usage into 8032
11228 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11229 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11231 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11232 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11234 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11235 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11237 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11239 * in /sdcc/as/mcs51/ changed these files in order to create an
11240 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11241 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11242 following files to include the previous two files: aslink.dsp,
11243 Makefile.aslink, Makefile.bcc, and Makefile.in.
11245 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11246 .adb instead of .cdb
11248 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11250 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11251 value from option --iram-size.
11253 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11255 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11258 2002-09-18 <wiml AT hhhh.org>
11260 * SDCClrange.h: exposed setFromRange() and setToRange()
11261 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11262 packRegsForAccUse() (bug 542397)
11263 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11264 multiple times and emitting the fetch operations more than once
11265 added aopGetUsesAcc() function to allow binary operators to
11266 fetch their operands in the correct order; made genMinus() emit
11267 compact code for X = LITERAL - Y
11269 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11270 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11271 sprintf() in line 1267.
11273 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11274 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11277 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11278 Changes to aslink (All the changes are marked with 'JCF'):
11280 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11283 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11284 area BSEG. Also moves, if possible, the DATA area down into the internal
11285 ram so more space is available.
11287 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11290 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11291 not bytes. Function summary() which creates a memory usage summary
11292 file with extension .mem. Reports of overlaping stack and small stack
11293 size. If the space for the stack is less than 16 bytes aslink trows a
11296 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11297 the 8051. Option 'y' for memory summary output file.
11299 Changes to sdcc (All the changes are marked with 'JCF'):
11301 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11303 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11304 overlaying area for it (uses RegBankUsed[4]).
11306 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11307 bank zero as used by default. By default aslink locates the stack
11308 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11309 the creation of the .mem file. Delegates the allocation of data area
11310 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11311 the begining of the stack area to aslink.
11313 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11314 glue() in SDCCglue.c creates an area for it.
11316 2002-09-03 Borut Razem <borut.razem AT siol.net>
11317 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11318 sdcc/src/pic/glue.c:
11319 introduced atexit() handler for teporay files removal in case of
11320 errors, assertions, ...
11322 2002-08-29 Borut Razem <borut.razem AT siol.net>
11323 * sdcc/support/cpp2/auto-host_vc_in.h:
11324 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11325 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11326 Maybe there is a similar problem with BORLANDC? It should be checked!
11328 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11329 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11330 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11331 was not executed, and the compiler (cl) launched a warning:
11332 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11334 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11335 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11337 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11338 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11340 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11341 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11342 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11343 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11344 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11345 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11346 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11347 - added Release configuration in VS projects
11348 - review of compiler an linker options
11349 - VC .exe files are generated in bin_vc directory, not to interfere
11350 with binaries generated from other projects (cygwin, mingw, bcc ...)
11352 * sdcc/src/yacc.dsp: added
11354 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11355 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11356 and insert the version number definitions from .version
11358 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11360 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11361 added - genarate auto-host.h using auto-host_vc_in.h as template
11364 removed from CVS, generated automatically
11366 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11367 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11369 2002-08-11 Borut Razem <borut.razem AT siol.net>
11370 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11372 2002-08-10 Borut Razem <borut.razem AT siol.net>
11373 * src/SDCCmain.c (main):
11374 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11375 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11376 The consequence was that some temporary files were not removed.
11379 unification of code in functions tempfilename() and tempfile():
11380 function tempnam() is defined in Visual Studio 6.0 and .NET
11382 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11384 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11385 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11386 - removed compiler command line option /WX: Treats all warnings as errors
11387 - update a list of source files, included into the project
11389 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11390 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11391 changed project type to Generic Project so that can be correcly converted to VS.NET project
11393 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11395 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11397 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11399 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11400 added return 0 statements after assert() to make compiler happy
11402 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11403 added newline in the def file to keep MSC compiler satisfied
11405 * sdcc/src/z80/gen.c:
11406 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11407 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11408 - solved MSC error in function aopDump()
11410 * sdcc_vc.h: define PREFIX as "\\sdcc"
11412 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11413 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11415 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11416 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11417 - Rewrote the register banking algorithm.
11418 - Added pCode live-range analysis to registers (for now, only non-used and
11419 singly-used registers optimized away)
11421 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11423 * 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.

11446 * src/z80/main.c: Added force callee saves for jaune.
11448 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11450 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11452 2002-03-28 Johan Knol <johan AT balder>
11454 * src/SDCCval.c: fixed bug #532436
11456 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11458 Added "char *Processor" field to the port structure.
11461 Added -p option. Allows port dependent processor to be specified.
11464 Initialized the new field char *Processor field to NULL in all ports
11467 Compiler generated registers for interrupt context saving
11468 were not getting allocated.
11470 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11473 Fixed left shift. Will promote the left side of a left shift
11474 if a) left shifting more than size of operand or b) when assigned
11475 to something size > size of left side
11477 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11479 tons of changes. Register allocation has been
11480 rewritten. Added customization for the various PICs. Flow
11481 analysis is restructured. ...
11483 * src/pic/device.h:
11486 * src/pic/device.c:
11487 Added. device.c is a PIC port hack to accomodate variations
11490 2002-03-13 Michael Hope <michaelh AT vroom>
11492 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11494 2002-03-04 johanknol <johanknol AT manik>
11496 * /src/SDCCval.c: fixed
11498 const unsigned char arr[][2] = { { 0, 1 } };
11499 t18.c:1: error: Initializer element is not constant

11585 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11587 * sdcc/src/SDCCloop.c:
11588 Previous fix was not good. basic blocks that have "break" or "return" are
11589 not really partof a loop , but live ranges used in these blocks should
11590 be live thru the entire loop, so set partOfLoop but don't add them to
11593 2002-02-21 <johan AT FRIJA>
11595 * src/SDCCcse.c: fixed bug #514308
11597 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11600 Fixed BUG #519583. If a conditional block ended in a return/break
11601 statement inside a loop, it was not being considered part of the loop.
11603 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
11605 2002-02-10 Karl Bongers <karl AT turbobit.com>

11611 * device/examples/test2.c:
11612 Fix bug, "red" variable not being initialized(compiler complained).
11614 * device/examples/Makefile, examples/test3.c:
11615 Add Makefile in device/examples folder, compiles test3.c
11616 for use as a multiple module SDCDB test case.
11618 * sim/ucsim/cmd.src/cmdset.cc:
11619 Took out debug printfs in ucsim "next" command.
11621 * sim/ucsim/xa.src:
11622 Karl and Johan start ucsim XA support. Most dissassembly working,
11623 about 75% emulation done(plenty of work remaining).
11625 * sim/ucsim/z80.src:
11626 Add Z80 support to ucsim, add test-ucz80 regression test,
11627 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
11628 Notice z80 compiler fails on examples/test3.c/crc code.
11630 2002-01-30 Sandeep Dutta <sandeep AT ddi.com>
11632 * src/mcs51/gen.c, src/mcs51/main.c, src/mcs51/ralloc.c:

11642 3) added __builtin_swapw swap bytes of a short
11644 * src/ds390/gen.c, src/ds390/gen.h, src/ds390/ralloc.c:
11645 1) handle multiple send & receives from register bank1
11646 2) ralloc can now allocate DPTR1 to some liveRanges
11648 * src/SDCCsymt.c, src/SDCCsymt.h:
11649 changes to handle multiple sends & receives
11651 * src/SDCCptropt.h:
11652 added some pointer arithmetic optimization
11654 * src/SDCCptropt.c:
11655 added some pointer arithmetic optimizations but not stable yet so not
11656 called from anywhere (will get this working shortly)
11658 * src/SDCCopt.c: fixed for multiple sends & receives
11661 1) added options --parms-in-bank1 (ds390/mcs51) & --protect-sp-update
11662 2) preprocessing done AFTER port->finalizeoptions . This allows ports to
11663 set preprocessor defines (depending on options)
11665 * src/SDCCicode.c, src/SDCCicode.h:
11666 changes made to handle multiple sends & receives
11669 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
