1724 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1726 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1727 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1729 One basic decision: e.g. src/clean.mk includes further files. In order
1730 to make this work there are two solutions:
1731 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1732 run configure on them. This way they can use
1733 'include $(srcdir)/port-clean.mk'
1734 - always include clean.mk by the Makefile at the same level. To avoid
1735 that `make clean` tries to include and build Makefile.dep the
1736 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1737 implemented, because now even `make uninstall` doesn't create
1738 Makefile.in. clean.mk could be eliminated by pasting it in
1741 * debugger/mcs51/Makefile.in: build own objects from library sources
1742 (SLIB, SDCC) in current directory
1744 * configure, configure.in: renamed --disable-device-lib-build in
1745 --disable-device-lib; added --enable-doc, the required tools are
1746 searched by configure; added result message; the toolchain for the
1747 belonging ports are now only built, if the port is enabled.
1749 * support/regression/*: all output is written in directory gen, because
1750 the fwk and ports directories don't livet in the build tree using vpath
1752 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1753 --disable-device-lib, added --enable-doc, added section VPATH
1755 * sim/ucsim/configure.in,
1756 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1757 z80 are enabled by default
1759 2006-04-24 Raphael Neider <rneider AT web.de>
1761 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1762 to config word, "pic14_"-prefixed some extern functions
1763 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1764 config word has been found
1765 * src/pic/device.h: added prototypes
1766 * src/pic/pcode.c: added "pic14_"-prefix where needed
1767 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1769 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config
1771 (pic14emitRegularMap): ignore config words,
1772 (pic14createInterruptVect): moved generating __config directives away
1773 (picglue): have __config directives emitted
1775 2006-04-24 Borut Razem <borut.razem AT siol.net>
1777 * doc/Makefile: sync with nightly build makefile
1779 2006-04-24 Raphael Neider <rneider AT web.de>
1781 * src/pic/pcoderegs.c (OptimizeRegUsage): do not optimize
1782 registers that have not been assigned proper liveranges,
1783 fixes #1469504 and #1474602,

2033 (genCritical, genEndCritical): added functions
2034 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
2035 * src/z80/mappings.i: added "ei" to all mappings

2052 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
2054 * src/.version: increased version number to 2.5.5
2055 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
2056 linking is done manually in pic16 port's _linkEdit,
2057 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
2058 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
2059 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
2060 allocate asmop as AOP_ACC,
2061 (aopForRemat): added parameter 'bool result' in function declaration,
2062 (pic16_aopGet): return AOP_ACC when accessing WREG,

2074 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
2075 call to allocReg, not by manually allocating a new one,
2076 (pic16_assignRegisters): now before going through the register
2077 allocating functions mark all registers as free. This eliminates some
2078 side effects resulting from peephole parser done earlier in the backbone
2080 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>

2138 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
2139 which dumps before the function entry point a data byte which represents
2140 the number of the local variables used by the specified function, added
2141 'xinst' for initial support for Extended Instruction Support,
2142 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
2143 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
2144 port->fun_prefix anymore (may change later),
2145 (genFunction, genEndFunction): do not store/restore local registers for
2146 _main (this should take care the --main-return command line option in
2148 (genOr): removed some legacy pic-port instructions,
2149 * src/pic16/genarith.c (genAddLit): re-enabled old code because
2150 performing operations with SFR's causes data to be written more than
2151 once to each SFR. Perhaps SFRs should be handled in special cases...
2152 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
2154 * src/pic16/main.c (_process_pragma): stack bound checking did not take

2159 (deassignLRs): *** perhaps the most important change, old 'for' code
2160 (commented out for reference), didn't account for some registers which
2161 were left marked 'not free' after a pointer operation. The change
2162 reduces register usage a lot in some cases

4431 2005-03-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
4433 * src/SDCCmain.c (setDefaultOptions, optionsTable[], parseCmdLine),

4435 * src/SDCCglobal.h (struct options),
4437 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
4438 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
4439 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
4440 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
4441 always available in leading double underscore form. The C99 support is
4442 mostly missing, but it's a start.
4443 * support/regression/tests/bug-227710.c: fixed nonconforming use of
4444 reserved identifier "__data".
4446 2005-03-24 Maarten Brock <sourceforge.brock AT dse.nl>

4522 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4524 * device/lib/printf_large.c: removed inline assembly for portability and
4525 readability. Use printf_fast if speed or size are more important.
4526 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4527 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4529 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4531 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4532 prevent compiler warning
4534 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4536 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4537 moved to level 0 and declared as static. Also they are explicit
4538 placed in access bank. This was necessery because some times they
4539 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4540 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4541 optimizations. Currently only compare to unsigned char is implemented,
4542 * src/pic16/gen.c: added fReturnIdx array,
4543 * (struct resolvedIfx) is moved to gen.h and made public,
4544 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4545 * (aopForSym): added an optimization to directly store in stack of
4546 the operand of a SEND iCode,
4547 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4548 but as registers instead (AOP_REG) using the fReturnIdx array,
4549 * (pic16_freeAsmop): remove the freed register from the
4550 _G.sregsAlloc field,
4551 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4552 a compare of 'WREG',
4553 * (pic16_popGetTempRegCond): changed function prototype, now
4554 function takes also a bitVector argument v which holds the current
4555 set of registers that are allocated for stack access by aopForSym,
4556 registers allocated in aopForSym for accessing stack symbols are not
4557 any more part of the functions usedRegs field,
4558 * (genCall): some times aopOp is called for a stack variable to be
4559 send, aopForSym might perform the push, if this is true make sure
4560 that genCall doesn't push the variable twice by testing _G.resDirect,
4561 * (genFunction): changed testing for unspecified interrupt number
4562 from 256 to INTNO_UNSPEC,
4563 * modified selection scheme of frame pointer generation. Previously
4564 if function did use local registers a frame pointer was generated,
4565 now a frame pointer is generated only if function has arguments
4566 (that need PLUSW2 register access), or has stack arguments, or the
4567 compiler is not instructed to omit the frame pointer,
4568 * (genEndFunction): before restoring local registers that were saved
4569 in the function preamble, also restore the registers that *might*
4570 have been allocated for stack access,
4571 * (genRet): removed some old comments,
4572 * (genCmp, the active (RN's) version): added a call to the
4573 pic16_genCmp_special function to perform the compare with a more
4574 robust and optimized way,
4575 * (genInline): a feature has been added in inline code generation,
4576 which allows a wildcard variable substitution when writing inline
4577 assembly. Code is incomplete and experimental therefore undocumented,
4578 * (genCast): changed order of aopOp for result and right to allow
4579 aopForSym to directly load the result if possible,
4580 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4581 perform an optimized compare on some selected special occasions,
4582 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4583 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4584 generate an IVT any more,
4585 * src/pic16/main.c (pic16_optionsTable): added command line option
4587 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4588 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4590 * src/pic16/NOTES: Raphael Neider added in list of active developers
4591 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4592 jumptable_end to prevent bug #,
4593 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4594 inCond and outCond fields,
4595 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4596 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4597 turn off register spilling,
4598 * (packRegsForOneUse): synced with other ports' versions although it
4599 is not used currently,
4600 * (pic16_packRegisters): added an optimization while reading
4601 structure bitfields, some registers may be saved (malloc code is
4602 decreased by 80 bytes)
4604 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4606 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4607 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4608 this can be optimized more?
4610 2005-03-10 Raphael Neider <rneider AT web.de>
4612 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4613 genNearPointerGet): (hopefully) fixed access to bitfields via
4614 pointers (p->bitN = x; and x = p->bitN; failed)
4616 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4660 to keep the correct label reference count when adding/removing references
4661 to labels. A peephole file using this is appended to patch #1144962.

5248 Adding support for replacing ljmps with sjmps in jumptables
5249 generated for switch statements. For now you need to set the
5250 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5251 Now 4 algorithms for mcs51 jumptable generation are used:
5252 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5253 addresses loaded pc-relative for up to 112 cases and stack-pushing
5254 target addresses loaded with offset from dptr for up to 256 cases.

5281 * device/lib/pic16/gstack.h: NEW, user can specify its own handler
5282 to call when a stack overflow occurs,
5283 * (malloc.h): added CVS Id tag,
5284 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5286 * added libc directory. The current version of LibC contains string
5287 functions, ctype functions and macros and some functions of the
5288 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5289 be extensively tested in the future. Standard disclaimer here.
5290 Library is not automatically build yet. But one can build it by
5291 invoking 'make' inside the libc directory.
5292 * added ADC library under libio. Preliminary version yet.
5294 * src/pic16/gen.h: added emitTOGC macro, to toggle Carry flag,

5301 * (genUminusFloat): fixed for pic16, ported code from mcs51,
5302 * (pic16_storeForReturn): optimized return of 0,
5303 * (genCmp): experimental code for new genCmp which uses PIC18's
5304 special compare&skip instructions. Initial tests fail some times
5305 with variables grater than 1 byte in size, so new code is disabled,
5306 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5308 * (genCast): began a fix to optimize the casting of a bit to another
5309 bit, now assigning a bitfield to another bitfield will fail, sorry,
5310 * src/pic16/main.c: disabled the use of lr-support feature,
5311 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

5314 bits with offset (case PO_GPR_BIT),
5315 * (genericPrint): don't emit INFO pcode when --pcode-verbose not in
5317 * (isBankInstruction): modified to return 0 for no banking instruction,
5318 and 1 for banking instruction,
5319 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5320 caused stop processing pCodes after a inline assembly block,
5321 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
5322 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
5323 registers when it shouldn't,
5324 * src/pic16/ralloc.c (allocReg): add preliminary support for
5325 supporting a limited set of temporary registers,
5327 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5329 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
5330 genDataPointerSet): ensure assignments always copy in MSB to LSB
5332 (loadRegFromAop): recognize CLRH optimization,
5333 (genFunction): optimize RECEIVE iCodes in reentrant functions
5335 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5337 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

8264 * src/pic/glue (pic14emitRegularMap),
8265 * src/pic16/glue.c (pic16emitRegularMap): updated call of decorateType()
8267 2004-01-23 Bernhard Held <bernhard AT bernhardheld.de>
8269 * src/pic/pcode.c (PCodeID): commented out left over debug code
8271 2004-01-20 Bernhard Held <bernhard AT bernhardheld.de>
8273 * support/valdiag/tests/overflow.c: added shift tests
8281 * src/pic/pcodepeep.c,
8282 * src/pic/pcoderegs.c,
8284 * src/pic/ralloc.h: applied patch from Slade Rich;
8285 added support for multiple code pages and multiple RAM banks on the
8286 PIC 14 port. The ASM files now no longer simply assume all the
8287 code / RAM are in the same page / bank. This means the linker can
8288 safely allocate code/RAM of separate ASM files to different pages/banks.
8289 * doc/sdccman.lyx: added Slade's tips
8290 * src/mcs51/peeph.def: fixed bug #880768

8299 * sim/ucsim/gui.src/serio.src/main.cc: Fixed unconditional use of
8302 * debugger/mcs51/cmd.c (getValBasic): Changed strtof to strtod as
8303 strtof is not part of C89 and isn't included with Mac OS X.
8305 2004-01-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8307 * src/hc08/gen.c (genPlusIncr, genUminus, genMinusDec, genCmp,

8332 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8334 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8335 loaded with the linker search paths (-L arguments) and the libraries
8336 to be linked with the current source (-l arguments). Changes
8337 currently will affect only the pic16 port.
8338 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8339 include path the port specific paths and port specific libraries,
8340 * gplink command now contains the $3 argument,
8341 * src/pic16/device.h,
8342 * src/pic16/device.c,: structure PIC_device is made public and
8343 renamed to PIC16_device, the same for variable Pics which is renamed
8344 to Pics16. Updated all references to them.
8345 * src/pic16/glue.c (pic16glue): corrected bug with code
8346 initialization which bypassed the variable initializations block.
8348 * device/lib/pic16/Makefile.rules: removed --penable-stack from
8349 COMPILE_FLAGS and added the --nostdinc option
8351 2004-01-15 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8358 Documenting changes from previous commits.
8359 * configure.in (version 1.56),
8360 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8361 when generating output files to configure the pic16 library,
8362 but now I've commented it out, since gputils aren't installed in the
8363 SF compile farm, so library won't compile
8365 * device/lib/Makefile.in (version 1.56): initially I've added in
8366 target 'all' the prerequestive 'model-pic16' so it compiled the
8367 pic16 library, but now I've commented it out for the same reasons
8369 * added targets 'model-pic16' and 'objects-pic16' to compile the
8371 * added target 'port-specific-objects-pic16' to handle the
8372 generated libraries and copy them into the build/ directory
8373 * added target 'clean-intermediate-pic16' to clean intermediate
8374 files into pic16 directory
8375 * in target 'installdirs' added line to create directory pic16 in
8376 the installation path
8378 * device/include/Makefile.in (version 1.11): in target 'install'
8379 added lines to copy all header files to installation path,
8380 * in target 'installdirs' added line create directory for pic16
8381 headers in the installation path

8396 * src/z80/main.c (_parseOptions): fixed the portmode= command line
8397 option so that it actually works. Made it specific to the z80, since
8398 the gbz80 doesn't have these kinds of I/O ports.
8400 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8402 * device/include/z180.h,

8415 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8417 * src/hc08/main.c (_hc08_genAssemblerPreamble): fixed bug #875487. Also
8418 changed interrupt vector table generation to only emit declared vectors.

8424 Mainly changes to support compilation of the device libraries
8425 * src/pic16/device.c: stack is allocated via symbol and not
8426 via literal number. The symbol is placed in the corresponding
8427 position of the data ram
8428 * (pic16_dump_section): relocatable and absolute uninitialized
8429 data are now emitted in sorted order to reduce section naming,
8430 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8431 weren't marked as being in the access bank,
8433 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
8435 Added portion of GNU PIC Library under the directory
8436 device/include/pic16 and device/lib/pic16. These files
8437 contain the declarations of SFRs for the PIC18Fxx2 devices.
8438 The directory is initialized via configure from toplevel.
8440 2004-01-12 Klaus Flittner <klaus_flittner AT gmx.de>
8442 * src/ds390/gen.c (operandsEqu): fixed a little typo, that prevented

8468 all over. Telling LaTeX to be less strict with word spacing
8469 to better keep the right margin. Changed some notes about
8470 maintainance of the ports in section 3.2.1 - is it OK like this?
8472 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

8510 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8512 * src/pic16/peeph.def: all peepholes with movff are commented out,
8513 because there is a problem in the pcode peep optimizer,
8514 * src/pic16/ralloc.c: the register allocator can now reuse local

8666 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8668 PIC16 port related changes:
8669 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8670 added variable stackPos,
8672 * gen.c: genCall, assignResultValue: added support for
8673 pushing/retrieving function parameters to/from stack,
8674 genFunction,genEndFunction: setup stack frame for the
8676 genAddrOf: will be changed according to bug 863624
8678 * added files genutils.c and genutils.h which contain gen*
8679 debugged and optimised functions extracted from gen.c
8681 * glue.c: added variable 'externs' which holds extern symbols,
8682 pic16emitRegularMap: is modified to properly handle relocatable
8683 symbols under the new scheme,
8684 pic16createInterruptVect: is modified
8685 pic16printPublics: is modified to emit 'global' assembler directives,
8686 added pic16_printExterns to print extern symbols,
8687 pic16glue: initializes stack/frame pointer in the beginning of
8688 the assembly output. Temporary hack, will be corrected later,
8689 because gplink yet does not support stack and SDCC does not
8690 yet support a type of crt0.o object to create the final binary.
8692 * Removed many lines that contain 8051 legacy code.
8693 * The code is finally placed under a 'code' directive.
8694 * Added port specific options.
8696 * _process_pragma: simplified since now we do not need *special*
8697 include file to define SFR registers. But a separate header
8698 will be needed. This will be developed later.
8699 * _pic16_parseOptions: added, parses port specific options:
8700 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8701 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8702 --preplace-udata-with=
8704 * _pic16_setDefaultOptions: modified to initialize section names,
8705 but hack is temporarly out of order since it needs improvement.
8706 * _pic16_genAssemblerPreamble: configuration words are emitted by
8707 their address instead of their name. This part is incomplete and
8708 supports only the 18Fxx2 devices. Other devices will emit an error
8709 during assembly since they do not contain the same set of config
8711 * _pic16_genIVT: is modified,
8713 * pcode.c: added definitions for some hardware registers that are needed
8715 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8716 All PCI entries are updated. Now LFSR is supported.
8717 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8718 * added pic16_newpCodeOpLit2 to support instructions with
8719 two literal arguments
8720 * pic16_pCode2str: corrected code that emits assembler instructions
8721 with two literal operands and those that have an access bit modifier
8722 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8723 this fixes a bug which caused some labels to be lost, when an
8724 assembler directive was added, i.e. banksel,
8725 * pic16_FixRegisterBanking: improved logic that causes the insertion
8727 * InlineFunction: functions that are called once, are not any more
8728 inlined. This can be a port option in the future,
8730 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8732 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8733 hold the corresponding uninitialized symbols,
8734 * pic16_allocProcessorRegister: registers have explicit marked the
8736 * pic16_allocInternalRegister: registers are explicit marked as
8738 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8739 processing list, so bit registers were lost,
8742 * ralloc.h: added field 'accessBank' and original symbol operand
8743 in register definition,
8744 * removed the field isMapped from register definition,
8746 ** Several functions have been removed from various sources:
8747 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8748 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8749 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8750 pic16_assignRelocatableRegisters
8752 ** others have been introduced:
8753 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8754 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8756 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8758 * support/scripts/inc2h.pl: changed definition of BIT_AT
8759 to emit 'sbit at' instead of 'bit at'. This was a request.
8761 PIC16 port related preliminary changes:
8762 * gen.c: prefixed function popRegFromString with
8763 pic16_ and all references to it corrected
8764 * pcode.c: all pic16_pc_* hardware registers prefixed
8765 with underscore (_),
8766 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8767 * ralloc.c: newReg(): when register is REG_SFR then
8768 set address to rIdx,
8769 pic16_allocProcessorRegister(): marks register wasUsed=0
8770 pic16_writeUsedRegs(): added a call to assign processor
8771 registers via pic16_assignFixedRegisters
8773 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8775 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8776 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8777 variables in unused register banks. Also the SSEG is placed
8778 wherever there is enough space for it, and IDATA can be anywhere
8779 in internal RAM. For now compile using -Wl-Y[stack_size].
8780 The mem file is different for this option as well, since it
8781 makes no sense of talking about DSEG lenght.
8783 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8785 * src/SDCClrange.c: fixed bug 869095 that caused segfault

9032 it breaks with bitfields, extern declarations, and gcse analysis.
9033 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
9034 could be assigned through a pointer, so don't complain.

9758 reported in bug #800609
9760 2003-09-04 Vangelis Rokas <vrokas AT otenet.gr>
9762 * Top header beautifications in src/pic16 directory:
9763 device.c, device.h, gen.c, gen.h, genarith.c, glue.c, pcode.c,
9764 pcodeflow.c, pcodeflow.h, pcode.h, pcodepeep.c, pcoderegs.c,
9765 pcoderegs.h, ralloc.c, ralloc.h
9766 * main.c: added top header and GPL license notice
9767 * pcode.c: fixed the if-conditional warning
9769 2003-09-04 Bernhard Held <bernhard AT bernhardheld.de>
9771 * device/lib/_mullong.c: replaced int by short for gcc
9773 2003-08-31 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9775 * src/SDCCpeeph.c (notVolatile, notVolatileVariable): handle IFX
9776 and JUMPTABLE iCodes properly now (worked by accident before)
9777 * src/mcs51/gen.c (leftRightUseAcc),
9778 * src/ds390/gen.c (leftRightUseAcc): handle IFX and JUMPTABLE
9779 iCode properly now. Use getSize instead of nRegs since a & b
9780 aren't part of the nRegs tally.
9782 2003-08-31 Vangelis Rokas <vrokas AT otenet.gr>
9784 * src/pic16/main.c: corrected offsets of interrupt vectors in _pic16_genIVT()
9785 * src/pic16/pcode.c: fix to disable inserting BANKSEL directive
9786 before instructions that use the _STATUS register
9788 2003-08-31 Bernhard Held <bernhard AT bernhardheld.de>
9790 * src/mcs51/gen.c (freeAsmop): fixed off by one in stack offset (AOP_STK)
9791 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9792 fetching of the pointer
9793 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9794 copied from genNearPointerSet()
9795 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9796 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9797 If they pop r0/r1 they must be called in the opposite order than aopOp().
9798 * device/lib/_mullong.c: fixed for "--model-large --int-long-reent"
9799 (resp. --stack-auto), prepared for --xstack
9801 2003-08-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9805 2003-08-28 Bernhard Held <bernhard AT bernhardheld.de>
9807 * device/lib/_startup.c: quick & dirty fix for ds390/ds400;
9808 these ports have their own __sdcc_external_start()
9810 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9812 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9813 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9814 type for bits was changed. It resulted in bit variables becoming
9815 global, which is not permitted in PIC 14 assembly output.
9817 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9819 * doc/sdccman.lyx: various additions and updates. Rearranged sections
9821 2003-08-22 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
9823 Z80 and MCS51 linkers complaint if a public symbol is defined
9824 in more than one library module:
9828 * as/mcs51/Makefile.in
9830 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9832 A few small changes that speed up the peephole optimizer.
9836 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9838 Try to make the peephole optimizer smarter by maintaining
9839 an association between the assembly source code and the
9840 iCodes that originated them. Put this information to use
9841 with a new peephole rule condition "notVolatile" so that
9842 the rules can be aggressive yet still safe.
9847 * src/mcs51/peeph.def
9849 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9853 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9854 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9855 if the left or right operand symbols have the accuse flag set.
9857 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9859 Changed the type of the result of the ! (NOT) operator to char;
9860 previously it returned the same type as the source. This allows
9861 us to eliminate all the genFloatNot functions (all of its target
9862 implementations were very buggy) since !float can use the same
9865 * src/SDCCicode.c (ast2iCode): ! returns char
9866 * src/mcs51/gen.c (genNot, genNotFloat),
9867 * src/ds390/gen.c (genNot, genNotFloat),
9868 * src/z80/gen.c (genNot, genNotFloat),
9869 * src/pic/gen.c (genNot, genNotFloat),
9870 * src/pic16/gen.c (genNot, genNotFloat): eliminated genNotFloat
9872 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9874 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9875 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9876 during interrupts. Ensure WSAVE is located at a shared bank address.
9877 2. Fixed page selection in some places
9878 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9879 the registers name strings.
9880 4. Fixed "signed / unsigned compare" compiler warnings.
9881 5. The PIC port manages its own allocation of the general purpose
9882 registers, but makes no attempt to reuse them. As a result when
9883 compiling it soon runs out of general purpose registers. Some
9884 additional code was added to the files pcode.c and device.c to walk
9885 through the function call tree and rename the registers so that they
9895 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9896 genPlus() & genMinus() when the result is the same as left or right

9902 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9904 Made bitfield a distinct type from bit so that bitfields
9905 convert as per ANSI C and bits retain their traditional
9906 boolean style behaviour. Implemented bitfield support in
9914 * src/ds390/gen.c: bit v bitfield split
9915 * src/z80/gen.c: New support for bitfields
9916 * support/regression/tests/bitfields.c: reenabled z80,
9919 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9921 Rules 246.x, 247.x relate to bitfields, the others speed up
9922 access to xdata mapped I/O devices.
9924 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9926 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9928 Cleaned up genPackBits and genUnpackBits and added two helper
9929 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9930 for literal assignments in genPackBits (thanks to Frieder for
9936 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9938 Fixed bug #748310 (pointer to function type mishandled when the
9939 function name is omitted). Also fixed a SIGSEGV when a function
9940 attribute (reentrant, etc) is used on a non-function or on a
9941 function but misplaced before the parameter list.
9943 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9945 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9946 * support/Util/SDCCerr.h,
9947 * support/Util/SDCCerr.c: Added func attr misuse error msg
9949 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9951 Fixed bug #787649 by anonymous
9952 * src/SDCCglue.c (emitRegularMap): added emission of sloc for func ptr
9953 * src/ds390/gen.c (aopForSym): fixed func ptr in sloc
9955 2003-08-14 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

9968 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9970 Made the constant following the "interrupt" keyword optional. If
9971 omitted, the function will not automatically be given an entry
9972 in the interrupt vector table (similar to #pragma NOIV, but
9973 less syntacticly kludgy). The interrupt number is also now
9974 range checked. Also fixed a bug in the high order bit example
9981 * support/Util/SDCCerr.c
9982 * support/Util/SDCCerr.h
9985 2003-08-13 Bernhard Held <bernhard AT bernhardheld.de>
9987 * src/SDCCcse.c (algebraicOpts): fix bug converting op from value to type
9988 * src/SDCCicode.c (operandOperation): rewritten some ops
9989 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9990 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9992 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9993 be re-activated by defining REDUCE_LITERALS)
9994 * src/SDCCval.c (constVal): fixed; hex and octal constants can be
9995 unsigned, but are signed by default
9996 * src/SDCCval.c (constVal): rearranged
9997 * src/SDCCval.c (valMod): preliminary fix
9998 * src/SDCCval.c (valCastLiteral): use TYPE_* types

10040 constants are unsigned; added recognition of "u" flag for unsigned
10041 * src/SDCCval.c (valMult): fixed signdness, added warning for overflow
10042 * src/SDCCval.c (valDiv, valMod): fixed signdness

10451 the regression tests I'm not brave enough to enable 245.b, 245.c
10452 * doc/sdccman.lyx: added latex preamble for hyperref package.
10453 Using pdflatex this will give you a hyperlinked pdf file with

10495 it can be defined with CFLAGS when running configure
10496 * src/SDCCmain.c: fixed compiling + linking with object files
10498 2003-05-18 Vangelis Rokas (vrokas AT otenet.gr)

10503 * src/SDCCmain.c: linkOptions is changed to set *,
10504 added if/endif conditional macros to remove options help
10505 messages from optionsTable when a port is not configured, added
10506 support for the PIc16 port in the ports table, when executing
10507 the compiler with no port specified on command line, a default
10508 port is selected with the new macro DEFAULT_PORT which is
10509 defined in port.h, in setDefaultOptions() linkOptions is removed
10510 from initialization assignment, since now it is a set,
10511 parseCmdLine uses setParseWithComma for linkOptions, in
10512 linkEdit() linkOptions are accessed with new function indexSet()
10513 which returns the i'th item of a set variable. See SDCCset.c, in
10514 linkEdit() when calling buildCmdLine(), added linkOptions as
10515 last argument. Now users can pass arguments to gplink via the
10516 -Wl option, main() uses pic16glue() to glue up pic16 programs

10528 * src/pic16/glue.c: commented out some error producing lines
10529 * src/pic16/main.c: __config directives are commented out to stop
10530 gpasm complaining and test the linkage with gplink, _linkCmd and
10531 _asmCmd changed to be more gplink and gpasm friendly
10532 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10533 produced an error when parsed, peep rule 12 is added to utilize
10534 movff, but it is commented out since the pCode does not support
10535 yet a command with 2 address arguments
10537 2003-05-18 <johan AT balder>
10539 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11594 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11595 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11597 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11598 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11600 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11602 * in /sdcc/as/mcs51/ changed these files in order to create an
11603 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11604 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11605 following files to include the previous two files: aslink.dsp,
11606 Makefile.aslink, Makefile.bcc, and Makefile.in.
11608 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11609 .adb instead of .cdb
11611 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11613 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11614 value from option --iram-size.
11616 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11618 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11621 2002-09-18 <wiml AT hhhh.org>
11623 * SDCClrange.h: exposed setFromRange() and setToRange()
11624 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11625 packRegsForAccUse() (bug 542397)
11626 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11627 multiple times and emitting the fetch operations more than once
11628 added aopGetUsesAcc() function to allow binary operators to
11629 fetch their operands in the correct order; made genMinus() emit
11630 compact code for X = LITERAL - Y
11632 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11633 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11634 sprintf() in line 1267.
11636 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11637 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11640 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11641 Changes to aslink (All the changes are marked with 'JCF'):
11643 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11646 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11647 area BSEG. Also moves, if possible, the DATA area down into the internal
11648 ram so more space is available.
11650 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11653 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11654 not bytes. Function summary() which creates a memory usage summary
11655 file with extension .mem. Reports of overlaping stack and small stack
11656 size. If the space for the stack is less than 16 bytes aslink trows a
11659 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11660 the 8051. Option 'y' for memory summary output file.
11662 Changes to sdcc (All the changes are marked with 'JCF'):
11664 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11666 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11667 overlaying area for it (uses RegBankUsed[4]).
11669 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11670 bank zero as used by default. By default aslink locates the stack
11671 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11672 the creation of the .mem file. Delegates the allocation of data area
11673 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11674 the begining of the stack area to aslink.
11676 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11677 glue() in SDCCglue.c creates an area for it.
11679 2002-09-03 Borut Razem <borut.razem AT siol.net>
11680 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11681 sdcc/src/pic/glue.c:
11682 introduced atexit() handler for teporay files removal in case of
11683 errors, assertions, ...
11685 2002-08-29 Borut Razem <borut.razem AT siol.net>
11686 * sdcc/support/cpp2/auto-host_vc_in.h:
11687 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11688 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11689 Maybe there is a similar problem with BORLANDC? It should be checked!
11691 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11692 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11693 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11694 was not executed, and the compiler (cl) launched a warning:
11695 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11697 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11698 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11700 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11701 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11703 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11704 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11705 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11706 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11707 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11708 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11709 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11710 - added Release configuration in VS projects
11711 - review of compiler an linker options
11712 - VC .exe files are generated in bin_vc directory, not to interfere
11713 with binaries generated from other projects (cygwin, mingw, bcc ...)
11715 * sdcc/src/yacc.dsp: added
11717 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11718 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11719 and insert the version number definitions from .version
11721 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11723 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11724 added - genarate auto-host.h using auto-host_vc_in.h as template
11727 removed from CVS, generated automatically
11729 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11730 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11732 2002-08-11 Borut Razem <borut.razem AT siol.net>
11733 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11735 2002-08-10 Borut Razem <borut.razem AT siol.net>
11736 * src/SDCCmain.c (main):
11737 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11738 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11739 The consequence was that some temporary files were not removed.
11742 unification of code in functions tempfilename() and tempfile():
11743 function tempnam() is defined in Visual Studio 6.0 and .NET
11745 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11747 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11748 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11749 - removed compiler command line option /WX: Treats all warnings as errors
11750 - update a list of source files, included into the project
11752 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11753 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11754 changed project type to Generic Project so that can be correcly converted to VS.NET project
11756 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11758 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11760 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11762 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11763 added return 0 statements after assert() to make compiler happy
11765 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11766 added newline in the def file to keep MSC compiler satisfied
11768 * sdcc/src/z80/gen.c:
11769 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11770 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11771 - solved MSC error in function aopDump()
11773 * sdcc_vc.h: define PREFIX as "\\sdcc"
11775 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11776 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11778 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11779 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11780 - Rewrote the register banking algorithm.
11781 - Added pCode live-range analysis to registers (for now, only non-used and
11782 singly-used registers optimized away)
11784 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11786 * 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.

11809 * src/z80/main.c: Added force callee saves for jaune.
11811 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
11813 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
11815 2002-03-28 Johan Knol <johan AT balder>
11817 * src/SDCCval.c: fixed bug #532436
11819 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11821 Added "char *Processor" field to the port structure.
11824 Added -p option. Allows port dependent processor to be specified.
11827 Initialized the new field char *Processor field to NULL in all ports
11830 Compiler generated registers for interrupt context saving
11831 were not getting allocated.
11833 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
11836 Fixed left shift. Will promote the left side of a left shift
11837 if a) left shifting more than size of operand or b) when assigned
11838 to something size > size of left side
11840 2002-03-14 Scott Dattalo <scott AT dattalo.com>
11842 tons of changes. Register allocation has been

11844 analysis is restructured. ...
11846 * src/pic/device.h:
11849 * src/pic/device.c:
11850 Added. device.c is a PIC port hack to accomodate variations
11853 2002-03-13 Michael Hope <michaelh AT vroom>
11855 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
11857 2002-03-04 johanknol <johanknol AT manik>
11859 * /src/SDCCval.c: fixed
11861 const unsigned char arr[][2] = { { 0, 1 } };

11948 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
11950 * sdcc/src/SDCCloop.c:
11951 Previous fix was not good. basic blocks that have "break" or "return" are
11952 not really partof a loop , but live ranges used in these blocks should
11953 be live thru the entire loop, so set partOfLoop but don't add them to
11956 2002-02-21 <johan AT FRIJA>
11958 * src/SDCCcse.c: fixed bug #514308
11960 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
