1716 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1718 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1719 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1721 One basic decision: e.g. src/clean.mk includes further files. In order
1722 to make this work there are two solutions:
1723 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1724 run configure on them. This way they can use
1725 'include $(srcdir)/port-clean.mk'
1726 - always include clean.mk by the Makefile at the same level. To avoid
1727 that `make clean` tries to include and build Makefile.dep the
1728 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1729 implemented, because now even `make uninstall` doesn't create
1730 Makefile.in. clean.mk could be eliminated by pasting it in
1733 * debugger/mcs51/Makefile.in: build own objects from library sources
1734 (SLIB, SDCC) in current directory
1736 * configure, configure.in: renamed --disable-device-lib-build in
1737 --disable-device-lib; added --enable-doc, the required tools are
1738 searched by configure; added result message; the toolchain for the
1739 belonging ports are now only built, if the port is enabled.
1741 * support/regression/*: all output is written in directory gen, because
1742 the fwk and ports directories don't livet in the build tree using vpath
1744 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1745 --disable-device-lib, added --enable-doc, added section VPATH
1747 * sim/ucsim/configure.in,
1748 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1749 z80 are enabled by default
1751 2006-04-24 Raphael Neider <rneider AT web.de>
1753 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1754 to config word, "pic14_"-prefixed some extern functions
1755 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1756 config word has been found
1757 * src/pic/device.h: added prototypes
1758 * src/pic/pcode.c: added "pic14_"-prefix where needed
1759 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1761 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
1763 (pic14emitRegularMap): ignore config words,
1764 (pic14createInterruptVect): moved generating __config directives away
1765 (picglue): have __config directives emitted
1767 2006-04-24 Borut Razem <borut.razem AT siol.net>
1769 * doc/Makefile: sync with nightly build makefile
1771 2006-04-24 Raphael Neider <rneider AT web.de>
1773 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
1774 registers that have not been assigned proper liveranges,
1775 fixes #1469504 and #1474602,
1776 (pCodeRegOptimizeRegUsage): fixed typo in comment
1778 2006-04-24 Borut Razem <borut.razem AT siol.net>
1780 * device/examples/main8051.c: deleted - it was removed from CVS
1781 24.mar.2000 and after that modified 18.feb.2001, so it reappered
1782 after the transition to Subversion
1783 * src/SDCCalloc.h: deleted - it was removed from CVS

2024 and enabled nesting of critical functions though not for gbz80
2025 (genCritical, genEndCritical): added functions
2026 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2027 * src/z80/mappings.i: added "ei" to all mappings

2044 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2046 * src/.version: increased version number to 2.5.5
2047 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2048 linking is done manually in pic16 port's _linkEdit,
2049 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2050 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2051 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2052 allocate asmop as AOP_ACC,
2053 (aopForRemat): added parameter 'bool result' in function declaration,
2054 (pic16_aopGet): return AOP_ACC when accessing WREG,

2066 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2067 call to allocReg, not by manually allocating a new one,
2068 (pic16_assignRegisters): now before going through the register
2069 allocating functions mark all registers as free. This eliminates some
2070 side effects resulting from peephole parser done earlier in the backbone
2072 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2130 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2131 which dumps before the function entry point a data byte which represents
2132 the number of the local variables used by the specified function, added
2133 'xinst' for initial support for Extended Instruction Support,
2134 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2135 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2136 port->fun_prefix anymore (may change later),
2137 (genFunction, genEndFunction): do not store/restore local registers for
2138 _main (this should take care the --main-return command line option in
2140 (genOr): removed some legacy pic-port instructions,
2141 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2142 performing operations with SFR's causes data to be written more than
2143 once to each SFR. Perhaps SFRs should be handled in special cases...
2144 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2146 * src/pic16/main.c (_process_pragma): stack bound checking did not take
2147 into account for stack starting position,

2151 (deassignLRs): *** perhaps the most important change, old 'for' code
2152 (commented out for reference), didn't account for some registers which
2153 were left marked 'not free' after a pointer operation. The change
2154 reduces register usage a lot in some cases
2156 2006-03-04 Borut Razem <borut.razem AT siol.net>

4429 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4430 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4431 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4432 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4433 always available in leading double underscore form. The C99 support is
4434 mostly missing, but it's a start.
4435 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4436 reserved identifier "__data".
4438 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

4514 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4516 * device/lib/printf_large.c: removed inline assembly for portability and
4517 readability. Use printf_fast if speed or size are more important.
4518 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4519 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4521 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4523 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4524 prevent compiler warning
4526 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4528 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4529 moved to level 0 and declared as static. Also they are explicit
4530 placed in access bank. This was necessery because some times they
4531 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4532 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4533 optimizations. Currently only compare to unsigned char is implemented,
4534 * src/pic16/gen.c: added fReturnIdx array,
4535 * (struct resolvedIfx) is moved to gen.h and made public,
4536 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4537 * (aopForSym): added an optimization to directly store in stack of
4538 the operand of a SEND iCode,
4539 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4540 but as registers instead (AOP_REG) using the fReturnIdx array,
4541 * (pic16_freeAsmop): remove the freed register from the
4542 _G.sregsAlloc field,
4543 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4544 a compare of 'WREG',
4545 * (pic16_popGetTempRegCond): changed function prototype, now
4546 function takes also a bitVector argument v which holds the current
4547 set of registers that are allocated for stack access by aopForSym,
4548 registers allocated in aopForSym for accessing stack symbols are not
4549 any more part of the functions usedRegs field,
4550 * (genCall): some times aopOp is called for a stack variable to be
4551 send, aopForSym might perform the push, if this is true make sure
4552 that genCall doesn't push the variable twice by testing _G.resDirect,
4553 * (genFunction): changed testing for unspecified interrupt number
4554 from 256 to INTNO_UNSPEC,
4555 * modified selection scheme of frame pointer generation. Previously
4556 if function did use local registers a frame pointer was generated,
4557 now a frame pointer is generated only if function has arguments
4558 (that need PLUSW2 register access), or has stack arguments, or the
4559 compiler is not instructed to omit the frame pointer,
4560 * (genEndFunction): before restoring local registers that were saved
4561 in the function preamble, also restore the registers that *might*
4562 have been allocated for stack access,
4563 * (genRet): removed some old comments,
4564 * (genCmp, the active (RN's) version): added a call to the
4565 pic16_genCmp_special function to perform the compare with a more
4566 robust and optimized way,
4567 * (genInline): a feature has been added in inline code generation,
4568 which allows a wildcard variable substitution when writing inline
4569 assembly. Code is incomplete and experimental therefore undocumented,
4570 * (genCast): changed order of aopOp for result and right to allow
4571 aopForSym to directly load the result if possible,
4572 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4573 perform an optimized compare on some selected special occasions,
4574 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4575 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4576 generate an IVT any more,
4577 * src/pic16/main.c (pic16_optionsTable): added command line option
4579 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4580 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4582 * src/pic16/NOTES: Raphael Neider added in list of active developers
4583 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4584 jumptable_end to prevent bug #,
4585 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4586 inCond and outCond fields,
4587 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4588 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4589 turn off register spilling,
4590 * (packRegsForOneUse): synced with other ports' versions although it
4591 is not used currently,
4592 * (pic16_packRegisters): added an optimization while reading
4593 structure bitfields, some registers may be saved (malloc code is
4594 decreased by 80 bytes)
4596 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4598 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4599 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4600 this can be optimized more?
4602 2005-03-10 Raphael Neider <rneider AT web.de>
4604 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4605 genNearPointerGet): (hopefully) fixed access to bitfields via
4606 pointers (p->bitN = x; and x = p->bitN; failed)

5240 Adding support for replacing ljmps with sjmps in jumptables
5241 generated for switch statements. For now you need to set the
5242 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5243 Now 4 algorithms for mcs51 jumptable generation are used:
5244 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5245 addresses loaded pc-relative for up to 112 cases and stack-pushing
5246 target addresses loaded with offset from dptr for up to 256 cases.

5273 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5274 to call when a stack overflow occurs,
5275 * (malloc.h): added CVS Id tag,
5276 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5278 * added libc directory. The current version of LibC contains string
5279 functions, ctype functions and macros and some functions of the
5280 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5281 be extensively tested in the future. Standard disclaimer here.
5282 Library is not automatically build yet. But one can build it by
5283 invoking 'make' inside the libc directory.
5284 * added ADC library under libio. Preliminary version yet.
5286 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

5293 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5294 * (pic16_storeForReturn): optimized return of 0,
5295 * (genCmp): experimental code for new genCmp which uses PIC18's
5296 special compare&skip instructions. Initial tests fail some times
5297 with variables grater than 1 byte in size, so new code is disabled,
5298 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5300 * (genCast): began a fix to optimize the casting of a bit to another
5301 bit, now assigning a bitfield to another bitfield will fail, sorry,
5302 * src/pic16/main.c: disabled the use of lr-support feature,
5303 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5306 bits with offset (case PO_GPR_BIT),
5307 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5309 * (isBankInstruction): modified to return 0 for no banking instruction,
5310 and 1 for banking instruction,
5311 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5312 caused stop processing pCodes after a inline assembly block,
5313 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5314 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5315 registers when it shouldn't,
5316 * src/pic16/ralloc.c (allocReg): add preliminary support for
5317 supporting a limited set of temporary registers,
5319 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5321 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5322 genDataPointerSet): ensure assignments always copy in MSB to LSB
5324 (loadRegFromAop): recognize CLRH optimization,
5325 (genFunction): optimize RECEIVE iCodes in reentrant functions
5327 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5329 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8276 * src/pic/ralloc.h: applied patch from Slade Rich;
8277 added support for multiple code pages and multiple RAM banks on the
8278 PIC 14 port. The ASM files now no longer simply assume all the
8279 code / RAM are in the same page / bank. This means the linker can
8280 safely allocate code/RAM of separate ASM files to different pages/banks.
8281 * doc/sdccman.lyx: added Slade's tips
8282 * src/mcs51/peeph.def: fixed bug #880768

8291 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
8294 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
8295 strtof is not part of C89 and isn't included with Mac OS X.
8297 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8299 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,
8300 shiftL2Left2Result): fixed bug #879326
8301 (genAnd, genOr, genXor): fixed bug when result was of type AOP_CRY

8324 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8326 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8327 loaded with the linker search paths (-L arguments) and the libraries
8328 to be linked with the current source (-l arguments). Changes
8329 currently will affect only the pic16 port.
8330 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8331 include path the port specific paths and port specific libraries,
8332 * gplink command now contains the $3 argument,
8333 * src/pic16/device.h,
8334 * src/pic16/device.c,: structure PIC_device is made public and
8335 renamed to PIC16_device, the same for variable Pics which is renamed
8336 to Pics16. Updated all references to them.
8337 * src/pic16/glue.c (pic16glue): corrected bug with code
8338 initialization which bypassed the variable initializations block.
8340 * device/lib/pic16/Makefile.rules: removed --penable-stack from
8341 COMPILE_FLAGS and added the --nostdinc option
8343 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8348 2004-01-14 Vangelis Rokas <vrokas AT otenet.gr>
8350 Documenting changes from previous commits.
8351 * configure.in (version 1.56),
8352 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8353 when generating output files to configure the pic16 library,
8354 but now I've commented it out, since gputils aren't installed in the
8355 SF compile farm, so library won't compile
8357 * device/lib/Makefile.in (version 1.56): initially I've added in
8358 target 'all' the prerequestive 'model-pic16' so it compiled the
8359 pic16 library, but now I've commented it out for the same reasons
8361 * added targets 'model-pic16' and 'objects-pic16' to compile the
8363 * added target 'port-specific-objects-pic16' to handle the
8364 generated libraries and copy them into the build/ directory
8365 * added target 'clean-intermediate-pic16' to clean intermediate
8366 files into pic16 directory
8367 * in target 'installdirs' added line to create directory pic16 in
8368 the installation path
8370 * device/include/Makefile.in (version 1.11): in target 'install'
8371 added lines to copy all header files to installation path,
8372 * in target 'installdirs' added line create directory for pic16
8373 headers in the installation path

8388 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8389 option so that it actually works. Made it specific to the z80, since
8390 the gbz80 doesn't have these kinds of I/O ports.
8392 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8394 * device/include/z180.h,

8407 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8409 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
8410 changed interrupt vector table generation to only emit declared vectors.

8416 Mainly changes to support compilation of the device libraries
8417 * src/pic16/device.c: stack is allocated via symbol and not
8418 via literal number. The symbol is placed in the corresponding
8419 position of the data ram
8420 * (pic16_dump_section): relocatable and absolute uninitialized
8421 data are now emitted in sorted order to reduce section naming,
8422 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8423 weren't marked as being in the access bank,
8425 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8427 Added portion of GNU PIC Library under the directory
8428 device/include/pic16 and device/lib/pic16. These files
8429 contain the declarations of SFRs for the PIC18Fxx2 devices.
8430 The directory is initialized via configure from toplevel.
8432 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8434 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented
8435 the spilllocations to be compared correctly

8460 all over. Telling LaTeX to be less strict with word spacing
8461 to better keep the right margin. Changed some notes about
8462 maintainance of the ports in section 3.2.1 - is it OK like this?
8464 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8502 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8504 * src/pic16/peeph.def: all peepholes with movff are commented out,
8505 because there is a problem in the pcode peep optimizer,
8506 * src/pic16/ralloc.c: the register allocator can now reuse local

8621 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8623 A python script to validate compiler diagnostic messages. It can be
8624 used to verify that sdcc complains about bad c source code and
8625 gives a good location of the error.
8626 * support/valdiag/Makefile,
8627 * support/valdiag/valdiag.py,
8628 * support/valdiag/tests/*

8658 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8660 PIC16 port related changes:
8661 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8662 added variable stackPos,
8664 * gen.c: genCall, assignResultValue: added support for
8665 pushing/retrieving function parameters to/from stack,
8666 genFunction,genEndFunction: setup stack frame for the
8668 genAddrOf: will be changed according to bug 863624
8670 * added files genutils.c and genutils.h which contain gen*
8671 debugged and optimised functions extracted from gen.c
8673 * glue.c: added variable 'externs' which holds extern symbols,
8674 pic16emitRegularMap: is modified to properly handle relocatable
8675 symbols under the new scheme,
8676 pic16createInterruptVect: is modified
8677 pic16printPublics: is modified to emit 'global' assembler directives,
8678 added pic16_printExterns to print extern symbols,
8679 pic16glue: initializes stack/frame pointer in the beginning of
8680 the assembly output. Temporary hack, will be corrected later,
8681 because gplink yet does not support stack and SDCC does not
8682 yet support a type of crt0.o object to create the final binary.
8684 * Removed many lines that contain 8051 legacy code.
8685 * The code is finally placed under a 'code' directive.
8686 * Added port specific options.
8688 * _process_pragma: simplified since now we do not need *special*
8689 include file to define SFR registers. But a separate header
8690 will be needed. This will be developed later.
8691 * _pic16_parseOptions: added, parses port specific options:
8692 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8693 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8694 --preplace-udata-with=
8696 * _pic16_setDefaultOptions: modified to initialize section names,
8697 but hack is temporarly out of order since it needs improvement.
8698 * _pic16_genAssemblerPreamble: configuration words are emitted by
8699 their address instead of their name. This part is incomplete and
8700 supports only the 18Fxx2 devices. Other devices will emit an error
8701 during assembly since they do not contain the same set of config
8703 * _pic16_genIVT: is modified,
8705 * pcode.c: added definitions for some hardware registers that are needed
8707 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8708 All PCI entries are updated. Now LFSR is supported.
8709 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8710 * added pic16_newpCodeOpLit2 to support instructions with
8711 two literal arguments
8712 * pic16_pCode2str: corrected code that emits assembler instructions
8713 with two literal operands and those that have an access bit modifier
8714 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8715 this fixes a bug which caused some labels to be lost, when an
8716 assembler directive was added, i.e. banksel,
8717 * pic16_FixRegisterBanking: improved logic that causes the insertion
8719 * InlineFunction: functions that are called once, are not any more
8720 inlined. This can be a port option in the future,
8722 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8724 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8725 hold the corresponding uninitialized symbols,
8726 * pic16_allocProcessorRegister: registers have explicit marked the
8728 * pic16_allocInternalRegister: registers are explicit marked as
8730 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8731 processing list, so bit registers were lost,
8734 * ralloc.h: added field 'accessBank' and original symbol operand
8735 in register definition,
8736 * removed the field isMapped from register definition,
8738 ** Several functions have been removed from various sources:
8739 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8740 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8741 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8742 pic16_assignRelocatableRegisters
8744 ** others have been introduced:
8745 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8746 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8748 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8750 * support/scripts/inc2h.pl: changed definition of BIT_AT
8751 to emit 'sbit at' instead of 'bit at'. This was a request.
8753 PIC16 port related preliminary changes:
8754 * gen.c: prefixed function popRegFromString with
8755 pic16_ and all references to it corrected
8756 * pcode.c: all pic16_pc_* hardware registers prefixed
8757 with underscore (_),
8758 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8759 * ralloc.c: newReg(): when register is REG_SFR then
8760 set address to rIdx,
8761 pic16_allocProcessorRegister(): marks register wasUsed=0
8762 pic16_writeUsedRegs(): added a call to assign processor
8763 registers via pic16_assignFixedRegisters
8765 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8767 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8768 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8769 variables in unused register banks. Also the SSEG is placed
8770 wherever there is enough space for it, and IDATA can be anywhere
8771 in internal RAM. For now compile using -Wl-Y[stack_size].
8772 The mem file is different for this option as well, since it
8773 makes no sense of talking about DSEG lenght.
8775 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8777 * src/SDCClrange.c: fixed bug 869095 that caused segfault

9768 and JUMPTABLE iCodes properly now (worked by accident before)
9769 * src/mcs51/gen.c (leftRightUseAcc),
9770 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
9771 iCode properly now. Use getSize instead of nRegs since a & b
9772 aren't part of the nRegs tally.
9774 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
9776 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
9777 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
9778 before instructions that use the _STATUS register
9780 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
9782 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9783 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9784 fetching of the pointer
9785 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9786 copied from genNearPointerSet()
9787 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9788 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9789 If they pop r0/r1 they must be called in the opposite order than aopOp().
9790 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9791 (resp. --stack-auto), prepared for --xstack

9797 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9799 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
9800 these ports have their own __sdcc_external_start()
9802 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9804 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9805 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9806 type for bits was changed. It resulted in bit variables becoming
9807 global, which is not permitted in PIC 14 assembly output.
9809 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9811 * doc/sdccman.lyx: various additions and updates. Rearranged sections

9824 A few small changes that speed up the peephole optimizer.
9828 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9830 Try to make the peephole optimizer smarter by maintaining
9831 an association between the assembly source code and the
9832 iCodes that originated them. Put this information to use
9833 with a new peephole rule condition "notVolatile" so that
9834 the rules can be aggressive yet still safe.
9839 * src/mcs51/peeph.def
9841 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9845 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9846 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9847 if the left or right operand symbols have the accuse flag set.
9849 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9851 Changed the type of the result of the ! (NOT) operator to char;
9852 previously it returned the same type as the source. This allows
9853 us to eliminate all the genFloatNot functions (all of its target
9854 implementations were very buggy) since !float can use the same
9857 * src/SDCCicode.c (ast2iCode): ! returns char

9859 * src/ds390/gen.c (genNot, genNotFloat),
9860 * src/z80/gen.c (genNot, genNotFloat),
9861 * src/pic/gen.c (genNot, genNotFloat),

9864 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9866 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9867 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9868 during interrupts. Ensure WSAVE is located at a shared bank address.
9869 2. Fixed page selection in some places
9870 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9871 the registers name strings.
9872 4. Fixed "signed / unsigned compare" compiler warnings.
9873 5. The PIC port manages its own allocation of the general purpose
9874 registers, but makes no attempt to reuse them. As a result when
9875 compiling it soon runs out of general purpose registers. Some
9876 additional code was added to the files pcode.c and device.c to walk
9877 through the function call tree and rename the registers so that they
9887 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9888 genPlus() & genMinus() when the result is the same as left or right

9894 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9896 Made bitfield a distinct type from bit so that bitfields
9897 convert as per ANSI C and bits retain their traditional
9898 boolean style behaviour. Implemented bitfield support in
9906 * src/ds390/gen.c: bit v bitfield split
9907 * src/z80/gen.c: New support for bitfields
9908 * support/regression/tests/bitfields.c: reenabled z80,
9911 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9913 Rules 246.x, 247.x relate to bitfields, the others speed up
9914 access to xdata mapped I/O devices.
9916 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9918 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9920 Cleaned up genPackBits and genUnpackBits and added two helper
9921 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9922 for literal assignments in genPackBits (thanks to Frieder for
9928 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9930 Fixed bug #748310 (pointer to function type mishandled when the
9931 function name is omitted). Also fixed a SIGSEGV when a function
9932 attribute (reentrant, etc) is used on a non-function or on a
9933 function but misplaced before the parameter list.
9935 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9937 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9938 * support/Util/SDCCerr.h,
9939 * support/Util/SDCCerr.c: Added func attr misuse error msg

9960 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9962 Made the constant following the "interrupt" keyword optional. If
9963 omitted, the function will not automatically be given an entry
9964 in the interrupt vector table (similar to #pragma NOIV, but
9965 less syntacticly kludgy). The interrupt number is also now
9966 range checked. Also fixed a bug in the high order bit example

9980 * src/SDCCicode.c (operandOperation): rewritten some ops
9981 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9982 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9984 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9985 be re-activated by defining REDUCE_LITERALS)
9986 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9987 unsigned, but are signed by default
9988 * src/SDCCval.c (constVal): rearranged
9989 * src/SDCCval.c (valMod): preliminary fix
9990 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10032 constants are unsigned; added recognition of "u" flag for unsigned
10033 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10034 * src/SDCCval.c (valDiv, valMod): fixed signdness

10442 * src/mcs51/peeph.def: added rules 244.x, 245.x. Although they pass
10443 the regression tests I'm not brave enough to enable 245.b, 245.c
10444 * doc/sdccman.lyx: added latex preamble for hyperref package.
10445 Using pdflatex this will give you a hyperlinked pdf file with
10446 bookmarks. (prepend '%' before /usepackage if this breaks something)

10487 it can be defined with CFLAGS when running configure
10488 * src/SDCCmain.c: fixed compiling + linking with object files
10490 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

10495 * src/SDCCmain.c: linkOptions is changed to set *,
10496 added if/endif conditional macros to remove options help
10497 messages from optionsTable when a port is not configured, added
10498 support for the PIc16 port in the ports table, when executing
10499 the compiler with no port specified on command line, a default
10500 port is selected with the new macro DEFAULT_PORT which is
10501 defined in port.h, in setDefaultOptions() linkOptions is removed
10502 from initialization assignment, since now it is a set,
10503 parseCmdLine uses setParseWithComma for linkOptions, in
10504 linkEdit() linkOptions are accessed with new function indexSet()
10505 which returns the i'th item of a set variable. See SDCCset.c, in
10506 linkEdit() when calling buildCmdLine(), added linkOptions as
10507 last argument. Now users can pass arguments to gplink via the
10508 -Wl option, main() uses pic16glue() to glue up pic16 programs

10520 * src/pic16/glue.c: commented out some error producing lines
10521 * src/pic16/main.c: __config directives are commented out to stop
10522 gpasm complaining and test the linkage with gplink, _linkCmd and
10523 _asmCmd changed to be more gplink and gpasm friendly
10524 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10525 produced an error when parsed, peep rule 12 is added to utilize
10526 movff, but it is commented out since the pCode does not support
10527 yet a command with 2 address arguments
10529 2003-05-18 <johan AT balder>
10531 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11595 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11596 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11597 following files to include the previous two files: aslink.dsp,
11598 Makefile.aslink, Makefile.bcc, and Makefile.in.
11600 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11601 .adb instead of .cdb
11603 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11605 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11606 value from option --iram-size.
11608 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11610 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11613 2002-09-18 <wiml AT hhhh.org>
11615 * SDCClrange.h: exposed setFromRange() and setToRange()
11616 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11617 packRegsForAccUse() (bug 542397)
11618 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11619 multiple times and emitting the fetch operations more than once
11620 added aopGetUsesAcc() function to allow binary operators to
11621 fetch their operands in the correct order; made genMinus() emit
11622 compact code for X = LITERAL - Y
11624 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11625 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11626 sprintf() in line 1267.
11628 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11629 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11632 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11633 Changes to aslink (All the changes are marked with 'JCF'):
11635 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11638 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11639 area BSEG. Also moves, if possible, the DATA area down into the internal
11640 ram so more space is available.
11642 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11645 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11646 not bytes. Function summary() which creates a memory usage summary
11647 file with extension .mem. Reports of overlaping stack and small stack
11648 size. If the space for the stack is less than 16 bytes aslink trows a
11651 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11652 the 8051. Option 'y' for memory summary output file.
11654 Changes to sdcc (All the changes are marked with 'JCF'):
11656 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11658 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11659 overlaying area for it (uses RegBankUsed[4]).
11661 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11662 bank zero as used by default. By default aslink locates the stack
11663 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11664 the creation of the .mem file. Delegates the allocation of data area
11665 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11666 the begining of the stack area to aslink.
11668 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11669 glue() in SDCCglue.c creates an area for it.
11671 2002-09-03 Borut Razem <borut.razem AT siol.net>
11672 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11673 sdcc/src/pic/glue.c:
11674 introduced atexit() handler for teporay files removal in case of
11675 errors, assertions, ...
11677 2002-08-29 Borut Razem <borut.razem AT siol.net>
11678 * sdcc/support/cpp2/auto-host_vc_in.h:
11679 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11680 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11681 Maybe there is a similar problem with BORLANDC? It should be checked!
11683 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11684 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11685 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11686 was not executed, and the compiler (cl) launched a warning:
11687 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11689 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11690 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11692 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11693 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11695 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11696 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11697 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11698 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11699 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11700 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11701 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11702 - added Release configuration in VS projects
11703 - review of compiler an linker options
11704 - VC .exe files are generated in bin_vc directory, not to interfere
11705 with binaries generated from other projects (cygwin, mingw, bcc ...)
11707 * sdcc/src/yacc.dsp: added
11709 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11710 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11711 and insert the version number definitions from .version
11713 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11715 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11716 added - genarate auto-host.h using auto-host_vc_in.h as template
11719 removed from CVS, generated automatically
11721 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11722 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11724 2002-08-11 Borut Razem <borut.razem AT siol.net>
11725 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11727 2002-08-10 Borut Razem <borut.razem AT siol.net>
11728 * src/SDCCmain.c (main):
11729 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11730 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11731 The consequence was that some temporary files were not removed.
11734 unification of code in functions tempfilename() and tempfile():
11735 function tempnam() is defined in Visual Studio 6.0 and .NET
11737 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11739 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11740 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11741 - removed compiler command line option /WX: Treats all warnings as errors
11742 - update a list of source files, included into the project
11744 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11745 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11746 changed project type to Generic Project so that can be correcly converted to VS.NET project
11748 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11750 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11752 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11754 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11755 added return 0 statements after assert() to make compiler happy
11757 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11758 added newline in the def file to keep MSC compiler satisfied
11760 * sdcc/src/z80/gen.c:
11761 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11762 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11763 - solved MSC error in function aopDump()
11765 * sdcc_vc.h: define PREFIX as "\\sdcc"
11767 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11768 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

11771 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11772 - Rewrote the register banking algorithm.
11773 - Added pCode live-range analysis to registers (for now, only non-used and
11774 singly-used registers optimized away)
11776 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11778 * 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.

11803 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11805 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11807 2002-03-28 Johan Knol <johan AT balder>
11809 * src/SDCCval.c: fixed bug #532436
11811 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11813 Added "char *Processor" field to the port structure.
11816 Added -p option. Allows port dependent processor to be specified.
11819 Initialized the new field char *Processor field to NULL in all ports
11822 Compiler generated registers for interrupt context saving
11823 were not getting allocated.
11825 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11828 Fixed left shift. Will promote the left side of a left shift
11829 if a) left shifting more than size of operand or b) when assigned
11830 to something size > size of left side
11832 2002-03-14 Scott Dattalo <scott AT dattalo.com>

11836 analysis is restructured. ...
11838 * src/pic/device.h:
11841 * src/pic/device.c:
11842 Added. device.c is a PIC port hack to accomodate variations

11940 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11942 * sdcc/src/SDCCloop.c:
11943 Previous fix was not good. basic blocks that have "break" or "return" are
11944 not really partof a loop , but live ranges used in these blocks should
11945 be live thru the entire loop, so set partOfLoop but don't add them to
11948 2002-02-21 <johan AT FRIJA>
11950 * src/SDCCcse.c: fixed bug #514308
11952 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
