1460 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1462 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1463 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1465 One basic decision: e.g. src/clean.mk includes further files. In order
1466 to make this work there are two solutions:
1467 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1468 run configure on them. This way they can use
1469 'include $(srcdir)/port-clean.mk'
1470 - always include clean.mk by the Makefile at the same level. To avoid
1471 that `make clean` tries to include and build Makefile.dep the
1472 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1473 implemented, because now even `make uninstall` doesn't create
1474 Makefile.in. clean.mk could be eliminated by pasting it in
1477 * debugger/mcs51/Makefile.in: build own objects from library sources
1478 (SLIB, SDCC) in current directory
1480 * configure, configure.in: renamed --disable-device-lib-build in
1481 --disable-device-lib; added --enable-doc, the required tools are
1482 searched by configure; added result message; the toolchain for the
1483 belonging ports are now only built, if the port is enabled.
1485 * support/regression/*: all output is written in directory gen, because
1486 the fwk and ports directories don't livet in the build tree using vpath
1488 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1489 --disable-device-lib, added --enable-doc, added section VPATH
1491 * sim/ucsim/configure.in,
1492 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1493 z80 are enabled by default
1495 2006-04-24 Raphael Neider <rneider AT web.de>
1497 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1498 to config word, "pic14_"-prefixed some extern functions
1499 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1500 config word has been found
1501 * src/pic/device.h: added prototypes
1502 * src/pic/pcode.c: added "pic14_"-prefix where needed

1505 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1520 (pCodeRegOptimizeRegUsage): fixed typo in comment

1524 * device/examples/main8051.c: deleted - it was removed from CVS

1785 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1788 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1790 * src/.version: increased version number to 2.5.5
1791 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1792 linking is done manually in pic16 port's _linkEdit,
1793 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1794 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1795 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1796 allocate asmop as AOP_ACC,
1797 (aopForRemat): added parameter 'bool result' in function declaration,
1798 (pic16_aopGet): return AOP_ACC when accessing WREG,
1799 (pic16_popGetTempReg): minor modification,
1800 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1801 'pic16_allocWithIdx',
1802 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1803 calling function in absolute addresses,
1804 (genAssign): take into account AOP_ACC asmop,
1805 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,
1806 * src/pic16/pcoderegs.c: some debug functions and lines added,
1807 * src/pic16/ralloc.c (decodeRegType): added but commented out,
1808 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1810 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1811 call to allocReg, not by manually allocating a new one,
1812 (pic16_assignRegisters): now before going through the register
1813 allocating functions mark all registers as free. This eliminates some
1814 side effects resulting from peephole parser done earlier in the backbone
1816 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

1837 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1838 (aopForSym, aopOp): increment asmop.allocated if reused,
1839 (freeAsmop): decrement asmop.allocated and check for zero instead of
1841 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1842 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,

1864 * support/regression/tests/array.c: added parenthesis, made arrays unsigned
1866 2006-03-06 Borut Razem <borut.razem AT siol.net>
1868 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1869 made the linker quiet
1871 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1873 * src/pic16/gen.c (genPcall): fixed bug #1443644
1874 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1875 which dumps before the function entry point a data byte which represents
1876 the number of the local variables used by the specified function, added
1877 'xinst' for initial support for Extended Instruction Support,
1878 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1879 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1880 port->fun_prefix anymore (may change later),
1881 (genFunction, genEndFunction): do not store/restore local registers for
1882 _main (this should take care the --main-return command line option in
1884 (genOr): removed some legacy pic-port instructions,
1885 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1886 performing operations with SFR's causes data to be written more than
1887 once to each SFR. Perhaps SFRs should be handled in special cases...
1888 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1890 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1891 into account for stack starting position,

1893 --extended or -y for Extended Instruction Support,
1894 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1895 (deassignLRs): *** perhaps the most important change, old 'for' code
1896 (commented out for reference), didn't account for some registers which
1897 were left marked 'not free' after a pointer operation. The change
1898 reduces register usage a lot in some cases

4175 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4176 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4177 always available in leading double underscore form. The C99 support is
4178 mostly missing, but it's a start.
4179 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4180 reserved identifier "__data".

4250 * src/SDCCicode.c (geniCodeSwitch, geniCodeJumpTable): fixed
4253 2005-03-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4255 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4256 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4258 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4260 * device/lib/printf_large.c: removed inline assembly for portability and
4261 readability. Use printf_fast if speed or size are more important.
4262 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4263 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4265 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4267 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4268 prevent compiler warning
4270 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4272 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4273 moved to level 0 and declared as static. Also they are explicit
4274 placed in access bank. This was necessery because some times they
4275 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4276 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4277 optimizations. Currently only compare to unsigned char is implemented,
4278 * src/pic16/gen.c: added fReturnIdx array,
4279 * (struct resolvedIfx) is moved to gen.h and made public,
4280 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4281 * (aopForSym): added an optimization to directly store in stack of
4282 the operand of a SEND iCode,
4283 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4284 but as registers instead (AOP_REG) using the fReturnIdx array,
4285 * (pic16_freeAsmop): remove the freed register from the
4286 _G.sregsAlloc field,
4287 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4288 a compare of 'WREG',
4289 * (pic16_popGetTempRegCond): changed function prototype, now
4290 function takes also a bitVector argument v which holds the current
4291 set of registers that are allocated for stack access by aopForSym,
4292 registers allocated in aopForSym for accessing stack symbols are not
4293 any more part of the functions usedRegs field,
4294 * (genCall): some times aopOp is called for a stack variable to be
4295 send, aopForSym might perform the push, if this is true make sure
4296 that genCall doesn't push the variable twice by testing _G.resDirect,
4297 * (genFunction): changed testing for unspecified interrupt number
4298 from 256 to INTNO_UNSPEC,
4299 * modified selection scheme of frame pointer generation. Previously
4300 if function did use local registers a frame pointer was generated,
4301 now a frame pointer is generated only if function has arguments
4302 (that need PLUSW2 register access), or has stack arguments, or the
4303 compiler is not instructed to omit the frame pointer,
4304 * (genEndFunction): before restoring local registers that were saved
4305 in the function preamble, also restore the registers that *might*
4306 have been allocated for stack access,
4307 * (genRet): removed some old comments,
4308 * (genCmp, the active (RN's) version): added a call to the
4309 pic16_genCmp_special function to perform the compare with a more
4310 robust and optimized way,
4311 * (genInline): a feature has been added in inline code generation,
4312 which allows a wildcard variable substitution when writing inline
4313 assembly. Code is incomplete and experimental therefore undocumented,
4314 * (genCast): changed order of aopOp for result and right to allow

4984 Adding support for replacing ljmps with sjmps in jumptables
4985 generated for switch statements. For now you need to set the
4986 environment variable SDCC_SJMP_JUMPTABLE to enable this.
4987 Now 4 algorithms for mcs51 jumptable generation are used:
4988 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target

5022 * added libc directory. The current version of LibC contains string
5023 functions, ctype functions and macros and some functions of the
5024 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5025 be extensively tested in the future. Standard disclaimer here.
5026 Library is not automatically build yet. But one can build it by

5038 * (pic16_storeForReturn): optimized return of 0,
5039 * (genCmp): experimental code for new genCmp which uses PIC18's
5040 special compare&skip instructions. Initial tests fail some times
5041 with variables grater than 1 byte in size, so new code is disabled,
5042 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5044 * (genCast): began a fix to optimize the casting of a bit to another
5045 bit, now assigning a bitfield to another bitfield will fail, sorry,

5054 and 1 for banking instruction,
5055 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5056 caused stop processing pCodes after a inline assembly block,
5057 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5059 registers when it shouldn't,
5060 * src/pic16/ralloc.c (allocReg): add preliminary support for
5061 supporting a limited set of temporary registers,
5063 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

5069 (genFunction): optimize RECEIVE iCodes in reentrant functions
5071 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8071 loaded with the linker search paths (-L arguments) and the libraries
8072 to be linked with the current source (-l arguments). Changes
8073 currently will affect only the pic16 port.
8074 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8075 include path the port specific paths and port specific libraries,
8076 * gplink command now contains the $3 argument,
8077 * src/pic16/device.h,
8078 * src/pic16/device.c,: structure PIC_device is made public and

8094 Documenting changes from previous commits.
8095 * configure.in (version 1.56),
8096 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8097 when generating output files to configure the pic16 library,
8098 but now I've commented it out, since gputils aren't installed in the
8099 SF compile farm, so library won't compile
8101 * device/lib/Makefile.in (version 1.56): initially I've added in
8102 target 'all' the prerequestive 'model-pic16' so it compiled the
8103 pic16 library, but now I've commented it out for the same reasons
8105 * added targets 'model-pic16' and 'objects-pic16' to compile the
8107 * added target 'port-specific-objects-pic16' to handle the
8108 generated libraries and copy them into the build/ directory
8109 * added target 'clean-intermediate-pic16' to clean intermediate
8110 files into pic16 directory
8111 * in target 'installdirs' added line to create directory pic16 in

8115 added lines to copy all header files to installation path,
8116 * in target 'installdirs' added line create directory for pic16
8117 headers in the installation path

8356 * src/SDCCast.c (decorateType),
8357 * src/SDCCicode.c (geniCodeLeftShift): added promotion to int for
8358 LEFT_OP (left shift)
8360 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8362 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8363 (default behaviour).
8365 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8367 A python script to validate compiler diagnostic messages. It can be
8368 used to verify that sdcc complains about bad c source code and
8369 gives a good location of the error.
8370 * support/valdiag/Makefile,
8371 * support/valdiag/valdiag.py,
8372 * support/valdiag/tests/*
8374 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8385 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8387 * src/common.h: added ifndef/define/endif macros
8388 around the header file.
8389 Bug reported from Jesus Calvino-Fraga
8391 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8393 * sdcc.spec: updated
8394 * device/include/Makefile.in: don't install CVS directories
8395 * device/lib/Makefile.in: added removal of CVS directories after install
8396 * doc/Makefile: fixed install, added local_icons
8397 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8398 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8399 * src/ds390/gen.c (genRightShift): fixed bug #870788
8400 * src/SDCCast.c (decorateType): fixed bug #870781
8402 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8404 PIC16 port related changes:
8405 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8406 added variable stackPos,
8408 * gen.c: genCall, assignResultValue: added support for
8409 pushing/retrieving function parameters to/from stack,
8410 genFunction,genEndFunction: setup stack frame for the
8412 genAddrOf: will be changed according to bug 863624
8414 * added files genutils.c and genutils.h which contain gen*
8415 debugged and optimised functions extracted from gen.c
8417 * glue.c: added variable 'externs' which holds extern symbols,
8418 pic16emitRegularMap: is modified to properly handle relocatable
8419 symbols under the new scheme,
8420 pic16createInterruptVect: is modified
8421 pic16printPublics: is modified to emit 'global' assembler directives,
8422 added pic16_printExterns to print extern symbols,
8423 pic16glue: initializes stack/frame pointer in the beginning of
8424 the assembly output. Temporary hack, will be corrected later,
8425 because gplink yet does not support stack and SDCC does not
8426 yet support a type of crt0.o object to create the final binary.
8428 * Removed many lines that contain 8051 legacy code.
8429 * The code is finally placed under a 'code' directive.
8430 * Added port specific options.
8432 * _process_pragma: simplified since now we do not need *special*
8433 include file to define SFR registers. But a separate header
8434 will be needed. This will be developed later.
8435 * _pic16_parseOptions: added, parses port specific options:
8436 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8437 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8438 --preplace-udata-with=
8440 * _pic16_setDefaultOptions: modified to initialize section names,
8441 but hack is temporarly out of order since it needs improvement.
8442 * _pic16_genAssemblerPreamble: configuration words are emitted by
8443 their address instead of their name. This part is incomplete and
8444 supports only the 18Fxx2 devices. Other devices will emit an error
8445 during assembly since they do not contain the same set of config
8447 * _pic16_genIVT: is modified,
8449 * pcode.c: added definitions for some hardware registers that are needed
8451 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8452 All PCI entries are updated. Now LFSR is supported.
8453 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8454 * added pic16_newpCodeOpLit2 to support instructions with
8455 two literal arguments
8456 * pic16_pCode2str: corrected code that emits assembler instructions
8457 with two literal operands and those that have an access bit modifier
8458 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8459 this fixes a bug which caused some labels to be lost, when an
8460 assembler directive was added, i.e. banksel,
8461 * pic16_FixRegisterBanking: improved logic that causes the insertion
8463 * InlineFunction: functions that are called once, are not any more
8464 inlined. This can be a port option in the future,
8466 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8468 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8469 hold the corresponding uninitialized symbols,
8470 * pic16_allocProcessorRegister: registers have explicit marked the
8472 * pic16_allocInternalRegister: registers are explicit marked as
8474 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8475 processing list, so bit registers were lost,
8478 * ralloc.h: added field 'accessBank' and original symbol operand
8479 in register definition,
8480 * removed the field isMapped from register definition,
8482 ** Several functions have been removed from various sources:
8483 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8484 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8485 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8486 pic16_assignRelocatableRegisters
8488 ** others have been introduced:
8489 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8490 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8492 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8494 * support/scripts/inc2h.pl: changed definition of BIT_AT
8495 to emit 'sbit at' instead of 'bit at'. This was a request.
8497 PIC16 port related preliminary changes:
8498 * gen.c: prefixed function popRegFromString with
8499 pic16_ and all references to it corrected
8500 * pcode.c: all pic16_pc_* hardware registers prefixed
8501 with underscore (_),
8502 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8503 * ralloc.c: newReg(): when register is REG_SFR then
8504 set address to rIdx,
8505 pic16_allocProcessorRegister(): marks register wasUsed=0
8506 pic16_writeUsedRegs(): added a call to assign processor
8507 registers via pic16_assignFixedRegisters
8509 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8511 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8512 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8513 variables in unused register banks. Also the SSEG is placed
8514 wherever there is enough space for it, and IDATA can be anywhere
8515 in internal RAM. For now compile using -Wl-Y[stack_size].
8516 The mem file is different for this option as well, since it
8517 makes no sense of talking about DSEG lenght.
8519 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8521 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8522 in certain cases, e.g. when ROM assignment, patch provided
8523 from Albert den Haan.

8764 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8766 * src/SDCCast.c (decorateType): disabled a transformation I added in
8767 revision 1.188 (access to fields of a structure at an absolute address);
8768 it breaks with bitfields, extern declarations, and gcse analysis.
8769 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
8770 could be assigned through a pointer, so don't complain.
8771 * src/SDCCast.c (astErrors),
8773 * src/SDCCglue.c (emitRegularMap): fixed bug #847813
8775 2003-11-26 Vangelis Rokas <vrokas AT otenet.gr>

9410 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
9411 support for standard C idiom of memory mapped variables; for
9412 example, *((xdata int*)0x1234) = 1 is now internally equivalent
9413 to xdata int at 0x1234 tempvar = 1.

9431 2003-09-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9433 Fixed bug #621531 (const & volatile confusion in the type chain).
9434 DCL_PTR_CONST, DCL_PTR_VOLATILE, & IS_PTR_CONST now exclusively

9526 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9527 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9528 fetching of the pointer
9529 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9530 copied from genNearPointerSet()
9531 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9532 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9533 If they pop r0/r1 they must be called in the opposite order than aopOp().
9534 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9535 (resp. --stack-auto), prepared for --xstack

9546 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9548 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9549 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9550 type for bits was changed. It resulted in bit variables becoming
9551 global, which is not permitted in PIC 14 assembly output.
9553 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9555 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9568 A few small changes that speed up the peephole optimizer.
9572 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9574 Try to make the peephole optimizer smarter by maintaining
9575 an association between the assembly source code and the
9576 iCodes that originated them. Put this information to use
9577 with a new peephole rule condition "notVolatile" so that
9578 the rules can be aggressive yet still safe.
9583 * src/mcs51/peeph.def
9585 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9589 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9590 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9591 if the left or right operand symbols have the accuse flag set.
9593 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9595 Changed the type of the result of the ! (NOT) operator to char;
9596 previously it returned the same type as the source. This allows
9597 us to eliminate all the genFloatNot functions (all of its target
9598 implementations were very buggy) since !float can use the same
9601 * src/SDCCicode.c (ast2iCode): ! returns char

9610 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9611 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9612 during interrupts. Ensure WSAVE is located at a shared bank address.
9613 2. Fixed page selection in some places
9614 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9615 the registers name strings.
9616 4. Fixed "signed / unsigned compare" compiler warnings.
9617 5. The PIC port manages its own allocation of the general purpose
9618 registers, but makes no attempt to reuse them. As a result when
9619 compiling it soon runs out of general purpose registers. Some
9620 additional code was added to the files pcode.c and device.c to walk
9621 through the function call tree and rename the registers so that they
9631 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9632 genPlus() & genMinus() when the result is the same as left or right

9638 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9640 Made bitfield a distinct type from bit so that bitfields
9641 convert as per ANSI C and bits retain their traditional
9642 boolean style behaviour. Implemented bitfield support in
9650 * src/ds390/gen.c: bit v bitfield split
9651 * src/z80/gen.c: New support for bitfields
9652 * support/regression/tests/bitfields.c: reenabled z80,
9655 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9657 Rules 246.x, 247.x relate to bitfields, the others speed up
9658 access to xdata mapped I/O devices.
9660 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9662 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9664 Cleaned up genPackBits and genUnpackBits and added two helper
9665 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9666 for literal assignments in genPackBits (thanks to Frieder for
9672 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9674 Fixed bug #748310 (pointer to function type mishandled when the
9675 function name is omitted). Also fixed a SIGSEGV when a function
9676 attribute (reentrant, etc) is used on a non-function or on a
9677 function but misplaced before the parameter list.
9679 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9681 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9682 * support/Util/SDCCerr.h,

9704 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9706 Made the constant following the "interrupt" keyword optional. If
9707 omitted, the function will not automatically be given an entry
9708 in the interrupt vector table (similar to #pragma NOIV, but
9709 less syntacticly kludgy). The interrupt number is also now
9710 range checked. Also fixed a bug in the high order bit example

9726 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9728 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9729 be re-activated by defining REDUCE_LITERALS)
9730 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9731 unsigned, but are signed by default
9732 * src/SDCCval.c (constVal): rearranged
9733 * src/SDCCval.c (valMod): preliminary fix
9734 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10240 added if/endif conditional macros to remove options help
10241 messages from optionsTable when a port is not configured, added
10242 support for the PIc16 port in the ports table, when executing
10243 the compiler with no port specified on command line, a default
10244 port is selected with the new macro DEFAULT_PORT which is
10245 defined in port.h, in setDefaultOptions() linkOptions is removed
10246 from initialization assignment, since now it is a set,
10247 parseCmdLine uses setParseWithComma for linkOptions, in
10248 linkEdit() linkOptions are accessed with new function indexSet()
10249 which returns the i'th item of a set variable. See SDCCset.c, in
10250 linkEdit() when calling buildCmdLine(), added linkOptions as
10251 last argument. Now users can pass arguments to gplink via the
10252 -Wl option, main() uses pic16glue() to glue up pic16 programs

10266 gpasm complaining and test the linkage with gplink, _linkCmd and
10267 _asmCmd changed to be more gplink and gpasm friendly
10268 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10269 produced an error when parsed, peep rule 12 is added to utilize
10270 movff, but it is commented out since the pCode does not support
10271 yet a command with 2 address arguments
10273 2003-05-18 <johan AT balder>
10275 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11330 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11331 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11333 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11334 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11336 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11338 * in /sdcc/as/mcs51/ changed these files in order to create an
11339 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11340 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11341 following files to include the previous two files: aslink.dsp,
11342 Makefile.aslink, Makefile.bcc, and Makefile.in.
11344 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11345 .adb instead of .cdb
11347 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11349 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11350 value from option --iram-size.
11352 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11354 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11357 2002-09-18 <wiml AT hhhh.org>
11359 * SDCClrange.h: exposed setFromRange() and setToRange()
11360 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11361 packRegsForAccUse() (bug 542397)
11362 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11363 multiple times and emitting the fetch operations more than once
11364 added aopGetUsesAcc() function to allow binary operators to
11365 fetch their operands in the correct order; made genMinus() emit
11366 compact code for X = LITERAL - Y
11368 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11369 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11370 sprintf() in line 1267.
11372 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11373 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11376 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11377 Changes to aslink (All the changes are marked with 'JCF'):
11379 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11382 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11383 area BSEG. Also moves, if possible, the DATA area down into the internal
11384 ram so more space is available.
11386 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11389 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11390 not bytes. Function summary() which creates a memory usage summary
11391 file with extension .mem. Reports of overlaping stack and small stack
11392 size. If the space for the stack is less than 16 bytes aslink trows a
11395 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11396 the 8051. Option 'y' for memory summary output file.
11398 Changes to sdcc (All the changes are marked with 'JCF'):
11400 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11402 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11403 overlaying area for it (uses RegBankUsed[4]).
11405 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11406 bank zero as used by default. By default aslink locates the stack
11407 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11408 the creation of the .mem file. Delegates the allocation of data area
11409 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11410 the begining of the stack area to aslink.
11412 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11413 glue() in SDCCglue.c creates an area for it.
11415 2002-09-03 Borut Razem <borut.razem AT siol.net>
11416 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11417 sdcc/src/pic/glue.c:
11418 introduced atexit() handler for teporay files removal in case of
11419 errors, assertions, ...
11421 2002-08-29 Borut Razem <borut.razem AT siol.net>
11422 * sdcc/support/cpp2/auto-host_vc_in.h:
11423 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11424 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11425 Maybe there is a similar problem with BORLANDC? It should be checked!
11427 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11428 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11429 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11430 was not executed, and the compiler (cl) launched a warning:
11431 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11433 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11434 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11436 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11437 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11439 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11440 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11441 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11442 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11443 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11444 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11445 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11446 - added Release configuration in VS projects
11447 - review of compiler an linker options
11448 - VC .exe files are generated in bin_vc directory, not to interfere
11449 with binaries generated from other projects (cygwin, mingw, bcc ...)
11451 * sdcc/src/yacc.dsp: added
11453 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11454 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11455 and insert the version number definitions from .version
11457 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11459 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11460 added - genarate auto-host.h using auto-host_vc_in.h as template
11463 removed from CVS, generated automatically
11465 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11466 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11468 2002-08-11 Borut Razem <borut.razem AT siol.net>
11469 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11471 2002-08-10 Borut Razem <borut.razem AT siol.net>
11472 * src/SDCCmain.c (main):
11473 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11474 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11475 The consequence was that some temporary files were not removed.
11478 unification of code in functions tempfilename() and tempfile():
11479 function tempnam() is defined in Visual Studio 6.0 and .NET
11481 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11483 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11484 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11485 - removed compiler command line option /WX: Treats all warnings as errors
11486 - update a list of source files, included into the project
11488 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11489 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11490 changed project type to Generic Project so that can be correcly converted to VS.NET project
11492 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11494 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11496 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11498 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11499 added return 0 statements after assert() to make compiler happy
11501 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11502 added newline in the def file to keep MSC compiler satisfied
11504 * sdcc/src/z80/gen.c:
11505 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11506 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11507 - solved MSC error in function aopDump()
11509 * sdcc_vc.h: define PREFIX as "\\sdcc"
11511 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11512 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11515 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11516 - Rewrote the register banking algorithm.
11517 - Added pCode live-range analysis to registers (for now, only non-used and
11518 singly-used registers optimized away)
11520 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11522 * 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.

11549 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11551 2002-03-28 Johan Knol <johan AT balder>
11553 * src/SDCCval.c: fixed bug #532436
11555 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11557 Added "char *Processor" field to the port structure.
11560 Added -p option. Allows port dependent processor to be specified.
11563 Initialized the new field char *Processor field to NULL in all ports
11566 Compiler generated registers for interrupt context saving
11567 were not getting allocated.
11569 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11572 Fixed left shift. Will promote the left side of a left shift
11573 if a) left shifting more than size of operand or b) when assigned
11574 to something size > size of left side
11576 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11578 tons of changes. Register allocation has been
11579 rewritten. Added customization for the various PICs. Flow
11580 analysis is restructured. ...
11582 * src/pic/device.h:
11585 * src/pic/device.c:
11586 Added. device.c is a PIC port hack to accomodate variations
11589 2002-03-13 Michael Hope <michaelh AT vroom>
11591 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11593 2002-03-04 johanknol <johanknol AT manik>
11595 * /src/SDCCval.c: fixed
11597 const unsigned char arr[][2] = { { 0, 1 } };
11598 t18.c:1: error: Initializer element is not constant
