1344 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1345 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1347 One basic decision: e.g. src/clean.mk includes further files. In order
1348 to make this work there are two solutions:
1349 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1350 run configure on them. This way they can use
1351 'include $(srcdir)/port-clean.mk'
1352 - always include clean.mk by the Makefile at the same level. To avoid
1353 that `make clean` tries to include and build Makefile.dep the
1354 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1355 implemented, because now even `make uninstall` doesn't create
1356 Makefile.in. clean.mk could be eliminated by pasting it in
1359 * debugger/mcs51/Makefile.in: build own objects from library sources
1360 (SLIB, SDCC) in current directory
1362 * configure, configure.in: renamed --disable-device-lib-build in
1363 --disable-device-lib; added --enable-doc, the required tools are
1364 searched by configure; added result message; the toolchain for the
1365 belonging ports are now only built, if the port is enabled.
1367 * support/regression/*: all output is written in directory gen, because
1368 the fwk and ports directories don't livet in the build tree using vpath
1370 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1371 --disable-device-lib, added --enable-doc, added section VPATH
1373 * sim/ucsim/configure.in,
1374 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1375 z80 are enabled by default
1377 2006-04-24 Raphael Neider <rneider AT web.de>
1379 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1380 to config word, "pic14_"-prefixed some extern functions
1381 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1382 config word has been found
1383 * src/pic/device.h: added prototypes
1384 * src/pic/pcode.c: added "pic14_"-prefix where needed
1385 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1387 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1662 2006-03-16 Raphael Neider <rneider AT web.de>
1664 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1665 the left operand is shorter than the result (c* = lit-c* + int),
1667 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1670 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1672 * src/.version: increased version number to 2.5.5
1673 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16

1675 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1676 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,

1678 allocate asmop as AOP_ACC,
1679 (aopForRemat): added parameter 'bool result' in function declaration,

1692 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1693 call to allocReg, not by manually allocating a new one,
1694 (pic16_assignRegisters): now before going through the register
1695 allocating functions mark all registers as free. This eliminates some
1696 side effects resulting from peephole parser done earlier in the backbone
1698 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1758 the number of the local variables used by the specified function, added
1759 'xinst' for initial support for Extended Instruction Support,
1760 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1761 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1762 port->fun_prefix anymore (may change later),
1763 (genFunction, genEndFunction): do not store/restore local registers for
1764 _main (this should take care the --main-return command line option in
1766 (genOr): removed some legacy pic-port instructions,
1767 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1768 performing operations with SFR's causes data to be written more than
1769 once to each SFR. Perhaps SFRs should be handled in special cases...
1770 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1772 * src/pic16/main.c (_process_pragma): stack bound checking did not take

4055 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4056 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4057 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4058 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4059 always available in leading double underscore form. The C99 support is

4140 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4142 * device/lib/printf_large.c: removed inline assembly for portability and
4143 readability. Use printf_fast if speed or size are more important.
4144 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4145 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4147 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4149 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4150 prevent compiler warning
4152 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4154 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4155 moved to level 0 and declared as static. Also they are explicit
4156 placed in access bank. This was necessery because some times they
4157 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4158 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4159 optimizations. Currently only compare to unsigned char is implemented,
4160 * src/pic16/gen.c: added fReturnIdx array,
4161 * (struct resolvedIfx) is moved to gen.h and made public,
4162 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4163 * (aopForSym): added an optimization to directly store in stack of
4164 the operand of a SEND iCode,
4165 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4166 but as registers instead (AOP_REG) using the fReturnIdx array,
4167 * (pic16_freeAsmop): remove the freed register from the
4168 _G.sregsAlloc field,
4169 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4170 a compare of 'WREG',
4171 * (pic16_popGetTempRegCond): changed function prototype, now
4172 function takes also a bitVector argument v which holds the current
4173 set of registers that are allocated for stack access by aopForSym,
4174 registers allocated in aopForSym for accessing stack symbols are not
4175 any more part of the functions usedRegs field,
4176 * (genCall): some times aopOp is called for a stack variable to be
4177 send, aopForSym might perform the push, if this is true make sure
4178 that genCall doesn't push the variable twice by testing _G.resDirect,
4179 * (genFunction): changed testing for unspecified interrupt number
4180 from 256 to INTNO_UNSPEC,
4181 * modified selection scheme of frame pointer generation. Previously
4182 if function did use local registers a frame pointer was generated,
4183 now a frame pointer is generated only if function has arguments
4184 (that need PLUSW2 register access), or has stack arguments, or the
4185 compiler is not instructed to omit the frame pointer,
4186 * (genEndFunction): before restoring local registers that were saved
4187 in the function preamble, also restore the registers that *might*
4188 have been allocated for stack access,
4189 * (genRet): removed some old comments,
4190 * (genCmp, the active (RN's) version): added a call to the
4191 pic16_genCmp_special function to perform the compare with a more
4192 robust and optimized way,
4193 * (genInline): a feature has been added in inline code generation,
4194 which allows a wildcard variable substitution when writing inline
4195 assembly. Code is incomplete and experimental therefore undocumented,
4196 * (genCast): changed order of aopOp for result and right to allow
4197 aopForSym to directly load the result if possible,
4198 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4199 perform an optimized compare on some selected special occasions,
4200 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4201 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4202 generate an IVT any more,
4203 * src/pic16/main.c (pic16_optionsTable): added command line option
4205 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4206 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4208 * src/pic16/NOTES: Raphael Neider added in list of active developers
4209 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4210 jumptable_end to prevent bug #,
4211 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4212 inCond and outCond fields,
4213 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4214 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4215 turn off register spilling,
4216 * (packRegsForOneUse): synced with other ports' versions although it
4217 is not used currently,
4218 * (pic16_packRegisters): added an optimization while reading
4219 structure bitfields, some registers may be saved (malloc code is
4220 decreased by 80 bytes)
4222 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4224 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4225 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4226 this can be optimized more?
4228 2005-03-10 Raphael Neider <rneider AT web.de>
4230 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4231 genNearPointerGet): (hopefully) fixed access to bitfields via
4232 pointers (p->bitN = x; and x = p->bitN; failed)

4277 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4278 to keep the correct label reference count when adding/removing references
4279 to labels. A peephole file using this is appended to patch #1144962.

4866 Adding support for replacing ljmps with sjmps in jumptables
4867 generated for switch statements. For now you need to set the
4868 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4869 Now 4 algorithms for mcs51 jumptable generation are used:
4870 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4871 addresses loaded pc-relative for up to 112 cases and stack-pushing
4872 target addresses loaded with offset from dptr for up to 256 cases.

4902 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
4904 * added libc directory. The current version of LibC contains string
4905 functions, ctype functions and macros and some functions of the
4906 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
4907 be extensively tested in the future. Standard disclaimer here.
4908 Library is not automatically build yet. But one can build it by
4909 invoking 'make' inside the libc directory.

4920 * (pic16_storeForReturn): optimized return of 0,
4921 * (genCmp): experimental code for new genCmp which uses PIC18's
4922 special compare&skip instructions. Initial tests fail some times
4923 with variables grater than 1 byte in size, so new code is disabled,
4924 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
4926 * (genCast): began a fix to optimize the casting of a bit to another
4927 bit, now assigning a bitfield to another bitfield will fail, sorry,

4938 caused stop processing pCodes after a inline assembly block,
4939 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

4941 registers when it shouldn't,
4942 * src/pic16/ralloc.c (allocReg): add preliminary support for
4943 supporting a limited set of temporary registers,
4945 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

4951 (genFunction): optimize RECEIVE iCodes in reentrant functions
4953 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

7833 2004-01-27 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7835 * ChangeLog: changed "@" to " AT " in hopes of reducing spam and
7836 virus/worm forged address usage.
7838 2004-01-27 Bernhard Held <bernhard AT bernhardheld.de>
7840 Fixed promotion, it should be done on AST level:
7841 * src/SDCCast.c (addCast): added promotion to int

7856 * support/regression/generate-cases.py (main): Changed from inline
7859 * doc/Makefile (install): Changed to depth first to get rid of
7860 missing directory install warning.
7862 * as/Makefile (install-doc): Made work on Mac.
7864 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
7866 * src/SDCCast.c: added an additional type flow in decorateType() of
7867 opposite direction, see feature request #860006; it's enabled at runtime
7868 by setting the environment variable SDCC_NEWTYPEFLOW
7869 * src/SDCCast.h: changed prototype of decorateType()
7870 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
7871 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from
7872 'char' to 'int' can be omitted, if both operands are 'unsigned char';
7873 see feature request #877103
7874 * src/SDCCval.c: updated call of decorateType()
7875 (valBitwise): fixed bug #882876
7876 (valMinus): added promotion
7877 (valLogicAndOr): result is unsigned
7878 (cheapestVal) (constVal): literals from 0...255 are 'unsigned char' now
7879 * src/SDCCsymt.c (computeType),
7880 * src/mcs51/gen.c (genCmpGt) (genCmpLt): literal 'unsigned char'

7902 * src/pic/ralloc.h: applied patch from Slade Rich;
7903 added support for multiple code pages and multiple RAM banks on the
7904 PIC 14 port. The ASM files now no longer simply assume all the
7905 code / RAM are in the same page / bank. This means the linker can
7906 safely allocate code/RAM of separate ASM files to different pages/banks.
7907 * doc/sdccman.lyx: added Slade's tips
7908 * src/mcs51/peeph.def: fixed bug #880768

7950 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
7952 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
7953 loaded with the linker search paths (-L arguments) and the libraries
7954 to be linked with the current source (-l arguments). Changes
7955 currently will affect only the pic16 port.
7956 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
7957 include path the port specific paths and port specific libraries,
7958 * gplink command now contains the $3 argument,
7959 * src/pic16/device.h,
7960 * src/pic16/device.c,: structure PIC_device is made public and
7961 renamed to PIC16_device, the same for variable Pics which is renamed

7976 Documenting changes from previous commits.
7977 * configure.in (version 1.56),
7978 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
7979 when generating output files to configure the pic16 library,
7980 but now I've commented it out, since gputils aren't installed in the
7981 SF compile farm, so library won't compile
7983 * device/lib/Makefile.in (version 1.56): initially I've added in
7984 target 'all' the prerequestive 'model-pic16' so it compiled the
7985 pic16 library, but now I've commented it out for the same reasons
7987 * added targets 'model-pic16' and 'objects-pic16' to compile the
7989 * added target 'port-specific-objects-pic16' to handle the
7990 generated libraries and copy them into the build/ directory
7991 * added target 'clean-intermediate-pic16' to clean intermediate
7992 files into pic16 directory
7993 * in target 'installdirs' added line to create directory pic16 in
7994 the installation path
7996 * device/include/Makefile.in (version 1.11): in target 'install'
7997 added lines to copy all header files to installation path,
7998 * in target 'installdirs' added line create directory for pic16
7999 headers in the installation path

8014 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8015 option so that it actually works. Made it specific to the z80, since
8016 the gbz80 doesn't have these kinds of I/O ports.
8018 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8020 * device/include/z180.h,

8044 via literal number. The symbol is placed in the corresponding
8045 position of the data ram
8046 * (pic16_dump_section): relocatable and absolute uninitialized
8047 data are now emitted in sorted order to reduce section naming,
8048 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8049 weren't marked as being in the access bank,
8051 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8053 Added portion of GNU PIC Library under the directory
8054 device/include/pic16 and device/lib/pic16. These files
8055 contain the declarations of SFRs for the PIC18Fxx2 devices.
8056 The directory is initialized via configure from toplevel.

8086 all over. Telling LaTeX to be less strict with word spacing
8087 to better keep the right margin. Changed some notes about
8088 maintainance of the ports in section 3.2.1 - is it OK like this?
8090 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8130 * src/pic16/peeph.def: all peepholes with movff are commented out,
8131 because there is a problem in the pcode peep optimizer,
8132 * src/pic16/ralloc.c: the register allocator can now reuse local

8284 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8286 PIC16 port related changes:
8287 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8288 added variable stackPos,
8290 * gen.c: genCall, assignResultValue: added support for
8291 pushing/retrieving function parameters to/from stack,
8292 genFunction,genEndFunction: setup stack frame for the
8294 genAddrOf: will be changed according to bug 863624
8296 * added files genutils.c and genutils.h which contain gen*
8297 debugged and optimised functions extracted from gen.c
8299 * glue.c: added variable 'externs' which holds extern symbols,
8300 pic16emitRegularMap: is modified to properly handle relocatable
8301 symbols under the new scheme,
8302 pic16createInterruptVect: is modified
8303 pic16printPublics: is modified to emit 'global' assembler directives,
8304 added pic16_printExterns to print extern symbols,
8305 pic16glue: initializes stack/frame pointer in the beginning of
8306 the assembly output. Temporary hack, will be corrected later,
8307 because gplink yet does not support stack and SDCC does not
8308 yet support a type of crt0.o object to create the final binary.
8310 * Removed many lines that contain 8051 legacy code.
8311 * The code is finally placed under a 'code' directive.
8312 * Added port specific options.
8314 * _process_pragma: simplified since now we do not need *special*
8315 include file to define SFR registers. But a separate header
8316 will be needed. This will be developed later.
8317 * _pic16_parseOptions: added, parses port specific options:
8318 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8319 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8320 --preplace-udata-with=
8322 * _pic16_setDefaultOptions: modified to initialize section names,
8323 but hack is temporarly out of order since it needs improvement.
8324 * _pic16_genAssemblerPreamble: configuration words are emitted by
8325 their address instead of their name. This part is incomplete and
8326 supports only the 18Fxx2 devices. Other devices will emit an error
8327 during assembly since they do not contain the same set of config
8329 * _pic16_genIVT: is modified,
8331 * pcode.c: added definitions for some hardware registers that are needed
8333 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8334 All PCI entries are updated. Now LFSR is supported.
8335 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8336 * added pic16_newpCodeOpLit2 to support instructions with
8337 two literal arguments
8338 * pic16_pCode2str: corrected code that emits assembler instructions
8339 with two literal operands and those that have an access bit modifier
8340 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8341 this fixes a bug which caused some labels to be lost, when an
8342 assembler directive was added, i.e. banksel,
8343 * pic16_FixRegisterBanking: improved logic that causes the insertion
8345 * InlineFunction: functions that are called once, are not any more
8346 inlined. This can be a port option in the future,
8348 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8350 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8351 hold the corresponding uninitialized symbols,
8352 * pic16_allocProcessorRegister: registers have explicit marked the
8354 * pic16_allocInternalRegister: registers are explicit marked as
8356 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8357 processing list, so bit registers were lost,
8360 * ralloc.h: added field 'accessBank' and original symbol operand
8361 in register definition,
8362 * removed the field isMapped from register definition,
8364 ** Several functions have been removed from various sources:
8365 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8366 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8367 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8368 pic16_assignRelocatableRegisters
8370 ** others have been introduced:
8371 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8372 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8374 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8376 * support/scripts/inc2h.pl: changed definition of BIT_AT
8377 to emit 'sbit at' instead of 'bit at'. This was a request.
8379 PIC16 port related preliminary changes:
8380 * gen.c: prefixed function popRegFromString with
8381 pic16_ and all references to it corrected
8382 * pcode.c: all pic16_pc_* hardware registers prefixed
8383 with underscore (_),
8384 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8385 * ralloc.c: newReg(): when register is REG_SFR then
8386 set address to rIdx,
8387 pic16_allocProcessorRegister(): marks register wasUsed=0
8388 pic16_writeUsedRegs(): added a call to assign processor
8389 registers via pic16_assignFixedRegisters
8391 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8393 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8394 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8395 variables in unused register banks. Also the SSEG is placed
8396 wherever there is enough space for it, and IDATA can be anywhere
8397 in internal RAM. For now compile using -Wl-Y[stack_size].
8398 The mem file is different for this option as well, since it
8399 makes no sense of talking about DSEG lenght.
8401 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8403 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8404 in certain cases, e.g. when ROM assignment, patch provided
8405 from Albert den Haan.

8648 * src/SDCCast.c (decorateType): disabled a transformation I added in
8649 revision 1.188 (access to fields of a structure at an absolute address);
8650 it breaks with bitfields, extern declarations, and gcse analysis.
8651 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8652 could be assigned through a pointer, so don't complain.

8760 xdata initialization slightly shorter
8762 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9409 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9410 fetching of the pointer
9411 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9412 copied from genNearPointerSet()
9413 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9414 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

9430 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9431 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9432 type for bits was changed. It resulted in bit variables becoming
9433 global, which is not permitted in PIC 14 assembly output.
9435 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9437 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9450 A few small changes that speed up the peephole optimizer.
9454 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9456 Try to make the peephole optimizer smarter by maintaining
9457 an association between the assembly source code and the
9458 iCodes that originated them. Put this information to use
9459 with a new peephole rule condition "notVolatile" so that
9460 the rules can be aggressive yet still safe.
9465 * src/mcs51/peeph.def
9467 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9471 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9472 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9473 if the left or right operand symbols have the accuse flag set.
9475 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9477 Changed the type of the result of the ! (NOT) operator to char;
9478 previously it returned the same type as the source. This allows
9479 us to eliminate all the genFloatNot functions (all of its target
9480 implementations were very buggy) since !float can use the same
9483 * src/SDCCicode.c (ast2iCode): ! returns char

9492 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9493 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9494 during interrupts. Ensure WSAVE is located at a shared bank address.
9495 2. Fixed page selection in some places
9496 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9497 the registers name strings.
9498 4. Fixed "signed / unsigned compare" compiler warnings.
9499 5. The PIC port manages its own allocation of the general purpose
9500 registers, but makes no attempt to reuse them. As a result when
9501 compiling it soon runs out of general purpose registers. Some
9502 additional code was added to the files pcode.c and device.c to walk
9503 through the function call tree and rename the registers so that they
9513 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9514 genPlus() & genMinus() when the result is the same as left or right

9520 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9522 Made bitfield a distinct type from bit so that bitfields
9523 convert as per ANSI C and bits retain their traditional
9524 boolean style behaviour. Implemented bitfield support in
9532 * src/ds390/gen.c: bit v bitfield split
9533 * src/z80/gen.c: New support for bitfields
9534 * support/regression/tests/bitfields.c: reenabled z80,
9537 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9539 Rules 246.x, 247.x relate to bitfields, the others speed up
9540 access to xdata mapped I/O devices.
9542 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9544 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9546 Cleaned up genPackBits and genUnpackBits and added two helper
9547 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9548 for literal assignments in genPackBits (thanks to Frieder for
9554 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9556 Fixed bug #748310 (pointer to function type mishandled when the
9557 function name is omitted). Also fixed a SIGSEGV when a function
9558 attribute (reentrant, etc) is used on a non-function or on a
9559 function but misplaced before the parameter list.
9561 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9563 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9564 * support/Util/SDCCerr.h,
9565 * support/Util/SDCCerr.c: Added func attr misuse error msg

9586 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9588 Made the constant following the "interrupt" keyword optional. If
9589 omitted, the function will not automatically be given an entry
9590 in the interrupt vector table (similar to #pragma NOIV, but
9591 less syntacticly kludgy). The interrupt number is also now
9592 range checked. Also fixed a bug in the high order bit example
9599 * support/Util/SDCCerr.c
9600 * support/Util/SDCCerr.h
9603 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9605 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
9606 * src/SDCCicode.c (operandOperation): rewritten some ops
9607 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9608 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9610 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9611 be re-activated by defining REDUCE_LITERALS)
9612 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9613 unsigned, but are signed by default
9614 * src/SDCCval.c (constVal): rearranged
9615 * src/SDCCval.c (valMod): preliminary fix
9616 * src/SDCCval.c (valCastLiteral): use TYPE_* types

9658 constants are unsigned; added recognition of "u" flag for unsigned
9659 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9660 * src/SDCCval.c (valDiv, valMod): fixed signdness
9661 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed
9662 signedness of modulo, left and right shift

10122 added if/endif conditional macros to remove options help
10123 messages from optionsTable when a port is not configured, added
10124 support for the PIc16 port in the ports table, when executing
10125 the compiler with no port specified on command line, a default
10126 port is selected with the new macro DEFAULT_PORT which is
10127 defined in port.h, in setDefaultOptions() linkOptions is removed
10128 from initialization assignment, since now it is a set,
10129 parseCmdLine uses setParseWithComma for linkOptions, in
10130 linkEdit() linkOptions are accessed with new function indexSet()
10131 which returns the i'th item of a set variable. See SDCCset.c, in
10132 linkEdit() when calling buildCmdLine(), added linkOptions as
10133 last argument. Now users can pass arguments to gplink via the
10134 -Wl option, main() uses pic16glue() to glue up pic16 programs

10146 * src/pic16/glue.c: commented out some error producing lines
10147 * src/pic16/main.c: __config directives are commented out to stop
10148 gpasm complaining and test the linkage with gplink, _linkCmd and
10149 _asmCmd changed to be more gplink and gpasm friendly
10150 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10151 produced an error when parsed, peep rule 12 is added to utilize
10152 movff, but it is commented out since the pCode does not support
10153 yet a command with 2 address arguments
10155 2003-05-18 <johan AT balder>
10157 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

10184 2003-05-11 Borut Razem <borut.razem AT siol.net>
10186 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
10187 the path of bin directory, so that PATH is the only env. variable, which has to be set

11198 2003-01-04 <johan AT balder>
11200 * src/SDCCval.c (getNelements): fixed the initialized array of structures
11202 2002-12-29 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11203 * as/mcs51/Makefile.bcc: fixed typo lkomf51.o -> lkaomf51.o
11205 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11206 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>
11207 * support/regression/tests/bug-524697.c: fit mem usage into 8032
11209 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11210 * src/mcs51/gen.c (aopGetUsesAcc): inserted missing "return FALSE"
11212 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11213 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11215 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11216 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11218 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11220 * in /sdcc/as/mcs51/ changed these files in order to create an
11221 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11222 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11223 following files to include the previous two files: aslink.dsp,
11224 Makefile.aslink, Makefile.bcc, and Makefile.in.
11226 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11227 .adb instead of .cdb
11229 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11231 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11232 value from option --iram-size.
11234 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11236 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11239 2002-09-18 <wiml AT hhhh.org>
11241 * SDCClrange.h: exposed setFromRange() and setToRange()
11242 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11243 packRegsForAccUse() (bug 542397)
11244 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11245 multiple times and emitting the fetch operations more than once
11246 added aopGetUsesAcc() function to allow binary operators to
11247 fetch their operands in the correct order; made genMinus() emit
11248 compact code for X = LITERAL - Y
11250 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11251 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11252 sprintf() in line 1267.
11254 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11255 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11258 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11259 Changes to aslink (All the changes are marked with 'JCF'):
11261 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11264 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11265 area BSEG. Also moves, if possible, the DATA area down into the internal
11266 ram so more space is available.
11268 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11271 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11272 not bytes. Function summary() which creates a memory usage summary
11273 file with extension .mem. Reports of overlaping stack and small stack
11274 size. If the space for the stack is less than 16 bytes aslink trows a
11277 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11278 the 8051. Option 'y' for memory summary output file.
11280 Changes to sdcc (All the changes are marked with 'JCF'):
11282 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11284 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11285 overlaying area for it (uses RegBankUsed[4]).
11287 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11288 bank zero as used by default. By default aslink locates the stack
11289 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11290 the creation of the .mem file. Delegates the allocation of data area
11291 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11292 the begining of the stack area to aslink.
11294 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11295 glue() in SDCCglue.c creates an area for it.
11297 2002-09-03 Borut Razem <borut.razem AT siol.net>
11298 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11299 sdcc/src/pic/glue.c:
11300 introduced atexit() handler for teporay files removal in case of
11301 errors, assertions, ...
11303 2002-08-29 Borut Razem <borut.razem AT siol.net>
11304 * sdcc/support/cpp2/auto-host_vc_in.h:
11305 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11306 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11307 Maybe there is a similar problem with BORLANDC? It should be checked!
11309 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11310 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11311 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11312 was not executed, and the compiler (cl) launched a warning:
11313 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11315 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11316 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11318 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11319 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11321 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11322 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11323 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11324 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11325 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11326 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11327 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11328 - added Release configuration in VS projects
11329 - review of compiler an linker options
11330 - VC .exe files are generated in bin_vc directory, not to interfere
11331 with binaries generated from other projects (cygwin, mingw, bcc ...)
11333 * sdcc/src/yacc.dsp: added
11335 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11336 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11337 and insert the version number definitions from .version
11339 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11341 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11342 added - genarate auto-host.h using auto-host_vc_in.h as template
11345 removed from CVS, generated automatically
11347 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11348 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11350 2002-08-11 Borut Razem <borut.razem AT siol.net>
11351 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11353 2002-08-10 Borut Razem <borut.razem AT siol.net>
11354 * src/SDCCmain.c (main):
11355 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11356 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11357 The consequence was that some temporary files were not removed.
11360 unification of code in functions tempfilename() and tempfile():
11361 function tempnam() is defined in Visual Studio 6.0 and .NET
11363 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11365 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11366 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11367 - removed compiler command line option /WX: Treats all warnings as errors
11368 - update a list of source files, included into the project
11370 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11371 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11372 changed project type to Generic Project so that can be correcly converted to VS.NET project
11374 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11376 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11378 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11380 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11381 added return 0 statements after assert() to make compiler happy
11383 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11384 added newline in the def file to keep MSC compiler satisfied
11386 * sdcc/src/z80/gen.c:
11387 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11388 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11389 - solved MSC error in function aopDump()
11391 * sdcc_vc.h: define PREFIX as "\\sdcc"
11393 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11394 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11397 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11398 - Rewrote the register banking algorithm.
11399 - Added pCode live-range analysis to registers (for now, only non-used and
11400 singly-used registers optimized away)
11402 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11404 * 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.

11431 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11433 2002-03-28 Johan Knol <johan AT balder>
11435 * src/SDCCval.c: fixed bug #532436
11437 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11439 Added "char *Processor" field to the port structure.
11442 Added -p option. Allows port dependent processor to be specified.
11445 Initialized the new field char *Processor field to NULL in all ports
11448 Compiler generated registers for interrupt context saving
11449 were not getting allocated.
11451 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11454 Fixed left shift. Will promote the left side of a left shift
11455 if a) left shifting more than size of operand or b) when assigned
11456 to something size > size of left side
11458 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11566 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11568 * sdcc/src/SDCCloop.c:
11569 Previous fix was not good. basic blocks that have "break" or "return" are
11570 not really partof a loop , but live ranges used in these blocks should
11571 be live thru the entire loop, so set partOfLoop but don't add them to
11574 2002-02-21 <johan AT FRIJA>
11576 * src/SDCCcse.c: fixed bug #514308
11578 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
11581 Fixed BUG #519583. If a conditional block ended in a return/break
