1467 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1469 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1470 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1472 One basic decision: e.g. src/clean.mk includes further files. In order
1473 to make this work there are two solutions:
1474 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1475 run configure on them. This way they can use
1476 'include $(srcdir)/port-clean.mk'
1477 - always include clean.mk by the Makefile at the same level. To avoid
1478 that `make clean` tries to include and build Makefile.dep the
1479 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1480 implemented, because now even `make uninstall` doesn't create
1481 Makefile.in. clean.mk could be eliminated by pasting it in
1484 * debugger/mcs51/Makefile.in: build own objects from library sources
1485 (SLIB, SDCC) in current directory
1487 * configure, configure.in: renamed --disable-device-lib-build in
1488 --disable-device-lib; added --enable-doc, the required tools are
1489 searched by configure; added result message; the toolchain for the
1490 belonging ports are now only built, if the port is enabled.
1492 * support/regression/*: all output is written in directory gen, because
1493 the fwk and ports directories don't livet in the build tree using vpath
1495 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1496 --disable-device-lib, added --enable-doc, added section VPATH
1498 * sim/ucsim/configure.in,
1499 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1500 z80 are enabled by default
1502 2006-04-24 Raphael Neider <rneider AT web.de>
1504 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1505 to config word, "pic14_"-prefixed some extern functions
1506 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1507 config word has been found
1508 * src/pic/device.h: added prototypes
1509 * src/pic/pcode.c: added "pic14_"-prefix where needed
1510 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1512 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1527 (pCodeRegOptimizeRegUsage): fixed typo in comment

1785 archive with gcc 4.1 on mips and wrote the patch"
1787 2006-03-16 Raphael Neider <rneider AT web.de>
1789 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1790 the left operand is shorter than the result (c* = lit-c* + int),
1792 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1795 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1797 * src/.version: increased version number to 2.5.5
1798 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1799 linking is done manually in pic16 port's _linkEdit,
1800 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1801 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1802 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1803 allocate asmop as AOP_ACC,
1804 (aopForRemat): added parameter 'bool result' in function declaration,
1805 (pic16_aopGet): return AOP_ACC when accessing WREG,
1806 (pic16_popGetTempReg): minor modification,
1807 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1808 'pic16_allocWithIdx',
1809 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1810 calling function in absolute addresses,
1811 (genAssign): take into account AOP_ACC asmop,
1812 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1813 * src/pic16/pcoderegs.c: some debug functions and lines added,
1814 * src/pic16/ralloc.c (decodeRegType): added but commented out,
1815 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1817 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1818 call to allocReg, not by manually allocating a new one,
1819 (pic16_assignRegisters): now before going through the register
1820 allocating functions mark all registers as free. This eliminates some
1821 side effects resulting from peephole parser done earlier in the backbone
1823 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1825 * src/SDCCicode.c (geniCodeLogic),

1843 * src/mcs51/gen.h: changed asmop.freed:1 to asmop.allocated for tracking
1844 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1845 (aopForSym, aopOp): increment asmop.allocated if reused,
1846 (freeAsmop): decrement asmop.allocated and check for zero instead of
1848 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1849 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

1873 2006-03-06 Borut Razem <borut.razem AT siol.net>
1875 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1876 made the linker quiet
1878 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1880 * src/pic16/gen.c (genPcall): fixed bug #1443644
1881 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1882 which dumps before the function entry point a data byte which represents
1883 the number of the local variables used by the specified function, added
1884 'xinst' for initial support for Extended Instruction Support,
1885 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1886 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1887 port->fun_prefix anymore (may change later),
1888 (genFunction, genEndFunction): do not store/restore local registers for
1889 _main (this should take care the --main-return command line option in
1891 (genOr): removed some legacy pic-port instructions,
1892 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1893 performing operations with SFR's causes data to be written more than
1894 once to each SFR. Perhaps SFRs should be handled in special cases...
1895 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1897 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1898 into account for stack starting position,
1899 (struct OPTIONS pic16_optionsTable): added command line argument
1900 --extended or -y for Extended Instruction Support,
1901 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1902 (deassignLRs): *** perhaps the most important change, old 'for' code
1903 (commented out for reference), didn't account for some registers which
1904 were left marked 'not free' after a pointer operation. The change
1905 reduces register usage a lot in some cases

4263 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4265 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4267 * device/lib/printf_large.c: removed inline assembly for portability and
4268 readability. Use printf_fast if speed or size are more important.
4269 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4270 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4272 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4274 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4275 prevent compiler warning
4277 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4279 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4280 moved to level 0 and declared as static. Also they are explicit
4281 placed in access bank. This was necessery because some times they
4282 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4283 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4284 optimizations. Currently only compare to unsigned char is implemented,
4285 * src/pic16/gen.c: added fReturnIdx array,
4286 * (struct resolvedIfx) is moved to gen.h and made public,
4287 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4288 * (aopForSym): added an optimization to directly store in stack of
4289 the operand of a SEND iCode,
4290 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4291 but as registers instead (AOP_REG) using the fReturnIdx array,
4292 * (pic16_freeAsmop): remove the freed register from the
4293 _G.sregsAlloc field,
4294 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4295 a compare of 'WREG',
4296 * (pic16_popGetTempRegCond): changed function prototype, now
4297 function takes also a bitVector argument v which holds the current
4298 set of registers that are allocated for stack access by aopForSym,
4299 registers allocated in aopForSym for accessing stack symbols are not
4300 any more part of the functions usedRegs field,
4301 * (genCall): some times aopOp is called for a stack variable to be
4302 send, aopForSym might perform the push, if this is true make sure
4303 that genCall doesn't push the variable twice by testing _G.resDirect,
4304 * (genFunction): changed testing for unspecified interrupt number
4305 from 256 to INTNO_UNSPEC,
4306 * modified selection scheme of frame pointer generation. Previously
4307 if function did use local registers a frame pointer was generated,
4308 now a frame pointer is generated only if function has arguments
4309 (that need PLUSW2 register access), or has stack arguments, or the
4310 compiler is not instructed to omit the frame pointer,
4311 * (genEndFunction): before restoring local registers that were saved
4312 in the function preamble, also restore the registers that *might*
4313 have been allocated for stack access,
4314 * (genRet): removed some old comments,
4315 * (genCmp, the active (RN's) version): added a call to the
4316 pic16_genCmp_special function to perform the compare with a more
4317 robust and optimized way,
4318 * (genInline): a feature has been added in inline code generation,
4319 which allows a wildcard variable substitution when writing inline
4320 assembly. Code is incomplete and experimental therefore undocumented,
4321 * (genCast): changed order of aopOp for result and right to allow
4322 aopForSym to directly load the result if possible,
4323 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,

4991 Adding support for replacing ljmps with sjmps in jumptables
4992 generated for switch statements. For now you need to set the
4993 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4994 Now 4 algorithms for mcs51 jumptable generation are used:
4995 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
4996 addresses loaded pc-relative for up to 112 cases and stack-pushing
4997 target addresses loaded with offset from dptr for up to 256 cases.

5027 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5029 * added libc directory. The current version of LibC contains string
5030 functions, ctype functions and macros and some functions of the
5031 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5032 be extensively tested in the future. Standard disclaimer here.
5033 Library is not automatically build yet. But one can build it by
5034 invoking 'make' inside the libc directory.

5045 * (pic16_storeForReturn): optimized return of 0,
5046 * (genCmp): experimental code for new genCmp which uses PIC18's
5047 special compare&skip instructions. Initial tests fail some times
5048 with variables grater than 1 byte in size, so new code is disabled,
5049 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5051 * (genCast): began a fix to optimize the casting of a bit to another
5052 bit, now assigning a bitfield to another bitfield will fail, sorry,

5061 and 1 for banking instruction,
5062 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5063 caused stop processing pCodes after a inline assembly block,
5064 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5066 registers when it shouldn't,
5067 * src/pic16/ralloc.c (allocReg): add preliminary support for
5068 supporting a limited set of temporary registers,
5070 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5076 (genFunction): optimize RECEIVE iCodes in reentrant functions
5078 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8078 loaded with the linker search paths (-L arguments) and the libraries
8079 to be linked with the current source (-l arguments). Changes
8080 currently will affect only the pic16 port.
8081 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8082 include path the port specific paths and port specific libraries,
8083 * gplink command now contains the $3 argument,
8084 * src/pic16/device.h,
8085 * src/pic16/device.c,: structure PIC_device is made public and

8101 Documenting changes from previous commits.
8102 * configure.in (version 1.56),
8103 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8104 when generating output files to configure the pic16 library,
8105 but now I've commented it out, since gputils aren't installed in the
8106 SF compile farm, so library won't compile
8108 * device/lib/Makefile.in (version 1.56): initially I've added in
8109 target 'all' the prerequestive 'model-pic16' so it compiled the
8110 pic16 library, but now I've commented it out for the same reasons
8112 * added targets 'model-pic16' and 'objects-pic16' to compile the
8114 * added target 'port-specific-objects-pic16' to handle the
8115 generated libraries and copy them into the build/ directory
8116 * added target 'clean-intermediate-pic16' to clean intermediate
8117 files into pic16 directory
8118 * in target 'installdirs' added line to create directory pic16 in

8322 directive when no overlay data exist
8323 * (picglue): modified to emit uninitialized data segment
8324 according to udata_section_name

8329 arguments via -W option
8330 * src/pic16/main.c: added $l in _asmCmd, changed extension for
8331 object file from '.rel' to '.o' in port->linker structure,

8363 * src/SDCCast.c (decorateType),
8364 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
8365 LEFT_OP (left shift)
8367 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8369 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8370 (default behaviour).
8372 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8374 A python script to validate compiler diagnostic messages. It can be
8375 used to verify that sdcc complains about bad c source code and
8376 gives a good location of the error.
8377 * support/valdiag/Makefile,
8378 * support/valdiag/valdiag.py,
8379 * support/valdiag/tests/*
8381 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8394 * src/common.h: added ifndef/define/endif macros
8395 around the header file.
8396 Bug reported from Jesus Calvino-Fraga
8398 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8400 * sdcc.spec: updated
8401 * device/include/Makefile.in: don't install CVS directories
8402 * device/lib/Makefile.in: added removal of CVS directories after install
8403 * doc/Makefile: fixed install, added local_icons
8404 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8405 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8406 * src/ds390/gen.c (genRightShift): fixed bug #870788
8407 * src/SDCCast.c (decorateType): fixed bug #870781
8409 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8411 PIC16 port related changes:
8412 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8413 added variable stackPos,
8415 * gen.c: genCall, assignResultValue: added support for
8416 pushing/retrieving function parameters to/from stack,
8417 genFunction,genEndFunction: setup stack frame for the
8419 genAddrOf: will be changed according to bug 863624
8421 * added files genutils.c and genutils.h which contain gen*
8422 debugged and optimised functions extracted from gen.c
8424 * glue.c: added variable 'externs' which holds extern symbols,
8425 pic16emitRegularMap: is modified to properly handle relocatable
8426 symbols under the new scheme,
8427 pic16createInterruptVect: is modified
8428 pic16printPublics: is modified to emit 'global' assembler directives,
8429 added pic16_printExterns to print extern symbols,
8430 pic16glue: initializes stack/frame pointer in the beginning of
8431 the assembly output. Temporary hack, will be corrected later,
8432 because gplink yet does not support stack and SDCC does not
8433 yet support a type of crt0.o object to create the final binary.
8435 * Removed many lines that contain 8051 legacy code.
8436 * The code is finally placed under a 'code' directive.
8437 * Added port specific options.
8439 * _process_pragma: simplified since now we do not need *special*
8440 include file to define SFR registers. But a separate header
8441 will be needed. This will be developed later.
8442 * _pic16_parseOptions: added, parses port specific options:
8443 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8444 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8445 --preplace-udata-with=
8447 * _pic16_setDefaultOptions: modified to initialize section names,
8448 but hack is temporarly out of order since it needs improvement.
8449 * _pic16_genAssemblerPreamble: configuration words are emitted by
8450 their address instead of their name. This part is incomplete and
8451 supports only the 18Fxx2 devices. Other devices will emit an error
8452 during assembly since they do not contain the same set of config
8454 * _pic16_genIVT: is modified,
8456 * pcode.c: added definitions for some hardware registers that are needed
8458 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8459 All PCI entries are updated. Now LFSR is supported.
8460 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8461 * added pic16_newpCodeOpLit2 to support instructions with
8462 two literal arguments
8463 * pic16_pCode2str: corrected code that emits assembler instructions
8464 with two literal operands and those that have an access bit modifier
8465 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8466 this fixes a bug which caused some labels to be lost, when an
8467 assembler directive was added, i.e. banksel,
8468 * pic16_FixRegisterBanking: improved logic that causes the insertion
8470 * InlineFunction: functions that are called once, are not any more
8471 inlined. This can be a port option in the future,
8473 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8475 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8476 hold the corresponding uninitialized symbols,
8477 * pic16_allocProcessorRegister: registers have explicit marked the
8479 * pic16_allocInternalRegister: registers are explicit marked as
8481 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8482 processing list, so bit registers were lost,
8485 * ralloc.h: added field 'accessBank' and original symbol operand
8486 in register definition,
8487 * removed the field isMapped from register definition,
8489 ** Several functions have been removed from various sources:
8490 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8491 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8492 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8493 pic16_assignRelocatableRegisters
8495 ** others have been introduced:
8496 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8497 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8499 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8501 * support/scripts/inc2h.pl: changed definition of BIT_AT
8502 to emit 'sbit at' instead of 'bit at'. This was a request.
8504 PIC16 port related preliminary changes:
8505 * gen.c: prefixed function popRegFromString with
8506 pic16_ and all references to it corrected
8507 * pcode.c: all pic16_pc_* hardware registers prefixed
8508 with underscore (_),
8509 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8510 * ralloc.c: newReg(): when register is REG_SFR then
8511 set address to rIdx,
8512 pic16_allocProcessorRegister(): marks register wasUsed=0
8513 pic16_writeUsedRegs(): added a call to assign processor
8514 registers via pic16_assignFixedRegisters
8516 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8518 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8519 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8520 variables in unused register banks. Also the SSEG is placed
8521 wherever there is enough space for it, and IDATA can be anywhere
8522 in internal RAM. For now compile using -Wl-Y[stack_size].
8523 The mem file is different for this option as well, since it
8524 makes no sense of talking about DSEG lenght.
8526 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8528 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8529 in certain cases, e.g. when ROM assignment, patch provided
8530 from Albert den Haan.

8771 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8773 * src/SDCCast.c (decorateType): disabled a transformation I added in
8774 revision 1.188 (access to fields of a structure at an absolute address);
8775 it breaks with bitfields, extern declarations, and gcse analysis.
8776 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8777 could be assigned through a pointer, so don't complain.
8778 * src/SDCCast.c (astErrors),
8780 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
8782 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

9534 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9535 fetching of the pointer
9536 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9537 copied from genNearPointerSet()
9538 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9539 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9540 If they pop r0/r1 they must be called in the opposite order than aopOp().
9541 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9542 (resp. --stack-auto), prepared for --xstack

9553 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9555 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9556 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9557 type for bits was changed. It resulted in bit variables becoming
9558 global, which is not permitted in PIC 14 assembly output.
9560 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9562 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9575 A few small changes that speed up the peephole optimizer.
9579 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9581 Try to make the peephole optimizer smarter by maintaining
9582 an association between the assembly source code and the
9583 iCodes that originated them. Put this information to use
9584 with a new peephole rule condition "notVolatile" so that
9585 the rules can be aggressive yet still safe.
9590 * src/mcs51/peeph.def
9592 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9596 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9597 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9598 if the left or right operand symbols have the accuse flag set.
9600 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9602 Changed the type of the result of the ! (NOT) operator to char;
9603 previously it returned the same type as the source. This allows
9604 us to eliminate all the genFloatNot functions (all of its target
9605 implementations were very buggy) since !float can use the same
9608 * src/SDCCicode.c (ast2iCode): ! returns char
9609 * src/mcs51/gen.c (genNot, genNotFloat),
9610 * src/ds390/gen.c (genNot, genNotFloat),
9611 * src/z80/gen.c (genNot, genNotFloat),
9612 * src/pic/gen.c (genNot, genNotFloat),

9617 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9618 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9619 during interrupts. Ensure WSAVE is located at a shared bank address.
9620 2. Fixed page selection in some places
9621 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9622 the registers name strings.
9623 4. Fixed "signed / unsigned compare" compiler warnings.
9624 5. The PIC port manages its own allocation of the general purpose
9625 registers, but makes no attempt to reuse them. As a result when
9626 compiling it soon runs out of general purpose registers. Some
9627 additional code was added to the files pcode.c and device.c to walk
9628 through the function call tree and rename the registers so that they
9638 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9639 genPlus() & genMinus() when the result is the same as left or right
9641 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9645 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9647 Made bitfield a distinct type from bit so that bitfields
9648 convert as per ANSI C and bits retain their traditional
9649 boolean style behaviour. Implemented bitfield support in
9657 * src/ds390/gen.c: bit v bitfield split
9658 * src/z80/gen.c: New support for bitfields
9659 * support/regression/tests/bitfields.c: reenabled z80,
9662 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9664 Rules 246.x, 247.x relate to bitfields, the others speed up
9665 access to xdata mapped I/O devices.
9667 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9669 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9671 Cleaned up genPackBits and genUnpackBits and added two helper
9672 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9673 for literal assignments in genPackBits (thanks to Frieder for
9679 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9681 Fixed bug #748310 (pointer to function type mishandled when the
9682 function name is omitted). Also fixed a SIGSEGV when a function
9683 attribute (reentrant, etc) is used on a non-function or on a
9684 function but misplaced before the parameter list.
9686 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9688 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9689 * support/Util/SDCCerr.h,
9690 * support/Util/SDCCerr.c: Added func attr misuse error msg

9711 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9713 Made the constant following the "interrupt" keyword optional. If
9714 omitted, the function will not automatically be given an entry
9715 in the interrupt vector table (similar to #pragma NOIV, but
9716 less syntacticly kludgy). The interrupt number is also now
9717 range checked. Also fixed a bug in the high order bit example

9733 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9735 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9736 be re-activated by defining REDUCE_LITERALS)

9783 constants are unsigned; added recognition of "u" flag for unsigned
9784 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
9785 * src/SDCCval.c (valDiv, valMod): fixed signdness
9786 * src/SDCCicode.c (operandOperation): fixed critical typo; fixed

10248 messages from optionsTable when a port is not configured, added
10249 support for the PIc16 port in the ports table, when executing
10250 the compiler with no port specified on command line, a default
10251 port is selected with the new macro DEFAULT_PORT which is
10252 defined in port.h, in setDefaultOptions() linkOptions is removed
10253 from initialization assignment, since now it is a set,
10254 parseCmdLine uses setParseWithComma for linkOptions, in
10255 linkEdit() linkOptions are accessed with new function indexSet()
10256 which returns the i'th item of a set variable. See SDCCset.c, in
10257 linkEdit() when calling buildCmdLine(), added linkOptions as
10258 last argument. Now users can pass arguments to gplink via the
10259 -Wl option, main() uses pic16glue() to glue up pic16 programs

10273 gpasm complaining and test the linkage with gplink, _linkCmd and
10274 _asmCmd changed to be more gplink and gpasm friendly
10275 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10276 produced an error when parsed, peep rule 12 is added to utilize
10277 movff, but it is commented out since the pCode does not support
10278 yet a command with 2 address arguments
10280 2003-05-18 <johan AT balder>

11340 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11341 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11343 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11345 * in /sdcc/as/mcs51/ changed these files in order to create an
11346 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11347 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11348 following files to include the previous two files: aslink.dsp,
11349 Makefile.aslink, Makefile.bcc, and Makefile.in.
11351 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11352 .adb instead of .cdb
11354 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11356 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11357 value from option --iram-size.
11359 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11361 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11364 2002-09-18 <wiml AT hhhh.org>
11366 * SDCClrange.h: exposed setFromRange() and setToRange()
11367 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11368 packRegsForAccUse() (bug 542397)
11369 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11370 multiple times and emitting the fetch operations more than once
11371 added aopGetUsesAcc() function to allow binary operators to
11372 fetch their operands in the correct order; made genMinus() emit
11373 compact code for X = LITERAL - Y
11375 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11376 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11377 sprintf() in line 1267.
11379 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11380 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11383 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11384 Changes to aslink (All the changes are marked with 'JCF'):
11386 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11389 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11390 area BSEG. Also moves, if possible, the DATA area down into the internal
11391 ram so more space is available.
11393 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11396 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11397 not bytes. Function summary() which creates a memory usage summary
11398 file with extension .mem. Reports of overlaping stack and small stack
11399 size. If the space for the stack is less than 16 bytes aslink trows a
11402 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11403 the 8051. Option 'y' for memory summary output file.
11405 Changes to sdcc (All the changes are marked with 'JCF'):
11407 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11409 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11410 overlaying area for it (uses RegBankUsed[4]).
11412 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11413 bank zero as used by default. By default aslink locates the stack
11414 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11415 the creation of the .mem file. Delegates the allocation of data area
11416 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11417 the begining of the stack area to aslink.
11419 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11420 glue() in SDCCglue.c creates an area for it.
11422 2002-09-03 Borut Razem <borut.razem AT siol.net>
11423 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11424 sdcc/src/pic/glue.c:
11425 introduced atexit() handler for teporay files removal in case of
11426 errors, assertions, ...
11428 2002-08-29 Borut Razem <borut.razem AT siol.net>
11429 * sdcc/support/cpp2/auto-host_vc_in.h:
11430 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11431 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11432 Maybe there is a similar problem with BORLANDC? It should be checked!
11434 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11435 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11436 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11437 was not executed, and the compiler (cl) launched a warning:
11438 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11440 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11441 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11443 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11444 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11446 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11447 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11448 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11449 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11450 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11451 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11452 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11453 - added Release configuration in VS projects
11454 - review of compiler an linker options
11455 - VC .exe files are generated in bin_vc directory, not to interfere
11456 with binaries generated from other projects (cygwin, mingw, bcc ...)
11458 * sdcc/src/yacc.dsp: added
11460 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11461 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11462 and insert the version number definitions from .version
11464 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11466 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11467 added - genarate auto-host.h using auto-host_vc_in.h as template
11470 removed from CVS, generated automatically
11472 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11473 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11475 2002-08-11 Borut Razem <borut.razem AT siol.net>
11476 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11478 2002-08-10 Borut Razem <borut.razem AT siol.net>
11479 * src/SDCCmain.c (main):
11480 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11481 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11482 The consequence was that some temporary files were not removed.
11485 unification of code in functions tempfilename() and tempfile():
11486 function tempnam() is defined in Visual Studio 6.0 and .NET
11488 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11490 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11491 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11492 - removed compiler command line option /WX: Treats all warnings as errors
11493 - update a list of source files, included into the project
11495 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11496 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11497 changed project type to Generic Project so that can be correcly converted to VS.NET project
11499 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11501 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11503 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11505 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11506 added return 0 statements after assert() to make compiler happy
11508 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11509 added newline in the def file to keep MSC compiler satisfied
11511 * sdcc/src/z80/gen.c:
11512 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11513 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11514 - solved MSC error in function aopDump()
11516 * sdcc_vc.h: define PREFIX as "\\sdcc"
11518 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11519 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11522 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11523 - Rewrote the register banking algorithm.
11524 - Added pCode live-range analysis to registers (for now, only non-used and
11525 singly-used registers optimized away)
11527 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11529 * 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.

11558 2002-03-28 Johan Knol <johan AT balder>
11560 * src/SDCCval.c: fixed bug #532436
11562 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11564 Added "char *Processor" field to the port structure.
11567 Added -p option. Allows port dependent processor to be specified.
11570 Initialized the new field char *Processor field to NULL in all ports
11573 Compiler generated registers for interrupt context saving
11574 were not getting allocated.
11576 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11579 Fixed left shift. Will promote the left side of a left shift
11580 if a) left shifting more than size of operand or b) when assigned
11581 to something size > size of left side
11583 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11585 tons of changes. Register allocation has been
11586 rewritten. Added customization for the various PICs. Flow
11587 analysis is restructured. ...
11589 * src/pic/device.h:
11592 * src/pic/device.c:
11593 Added. device.c is a PIC port hack to accomodate variations
11596 2002-03-13 Michael Hope <michaelh AT vroom>
11598 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11600 2002-03-04 johanknol <johanknol AT manik>
11602 * /src/SDCCval.c: fixed
11604 const unsigned char arr[][2] = { { 0, 1 } };
11605 t18.c:1: error: Initializer element is not constant
