1527 2006-04-24 Bernhard Held <bernhard AT bernhardheld.de>
1529 Enabled VPATH feature: changed nearly all Makefiles (149 files).
1530 See sdccman.lyx '2.4.10 VPATH feature' about how to use it.
1532 One basic decision: e.g. src/clean.mk includes further files. In order
1533 to make this work there are two solutions:
1534 - rename another dozen clean.mk to clean_in.mk, add srcdir to them and
1535 run configure on them. This way they can use
1536 'include $(srcdir)/port-clean.mk'
1537 - always include clean.mk by the Makefile at the same level. To avoid
1538 that `make clean` tries to include and build Makefile.dep the
1539 MAKECMDGOALS are examined (see e.g. src/Makefile.in). This has been
1540 implemented, because now even `make uninstall` doesn't create
1541 Makefile.in. clean.mk could be eliminated by pasting it in
1544 * debugger/mcs51/Makefile.in: build own objects from library sources
1545 (SLIB, SDCC) in current directory
1547 * configure, configure.in: renamed --disable-device-lib-build in
1548 --disable-device-lib; added --enable-doc, the required tools are
1549 searched by configure; added result message; the toolchain for the
1550 belonging ports are now only built, if the port is enabled.
1552 * support/regression/*: all output is written in directory gen, because
1553 the fwk and ports directories don't livet in the build tree using vpath
1555 * doc/sdccman.lyx: renamed --disable-device-lib-build to
1556 --disable-device-lib, added --enable-doc, added section VPATH
1558 * sim/ucsim/configure.in,
1559 * sim/ucsim/configure.in: hc08 couldn't be disabled, now hc08 and
1560 z80 are enabled by default
1562 2006-04-24 Raphael Neider <rneider AT web.de>
1564 * src/pic/device.c (pic14_assignConfigWordValue): remember assignments
1565 to config word, "pic14_"-prefixed some extern functions
1566 (pic14_emitConfigWord): emit __config directive(s) if assignment to
1567 config word has been found
1568 * src/pic/device.h: added prototypes
1569 * src/pic/pcode.c: added "pic14_"-prefix where needed
1570 * src/pic/ralloc.c (IS_CONFIG_ADDRESS,pic14_assignRegisters): cosmetic
1572 * src/pic/glue.c (pic14_constructAbsMap): handle assignments to config

1810 2006-04-05 Maarten Brock <sourceforge.brock AT dse.nl>
1812 * src/mcs51/gen.c (genCall): fixed bug 1457608
1814 2006-03-30 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1819 2006-03-29 Maarten Brock <sourceforge.brock AT dse.nl>
1821 * src/SDCCpeeph.c (operandsLiteral): new, added,

1832 * src/z80/gen.c (genFunction, genEndFunction): fixed bug 1160666,
1833 implemented patch 1120823 Thanks to Willy De la Court (normal
1834 interrupts need an interrupt number now if they are made critical),
1835 and enabled nesting of critical functions though not for gbz80
1836 (genCritical, genEndCritical): added functions
1837 (genZ80Code): added cases for CRITICAL and ENDCRITICAL
1838 * src/z80/mappings.i: added "ei" to all mappings
1840 2006-03-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

1843 submitted by the Debian SDCC maintainer Aurelien Jarno:
1844 "Credits goes to Martin Michlmayr, who rebuilt the whole Debian
1845 archive with gcc 4.1 on mips and wrote the patch"
1847 2006-03-16 Raphael Neider <rneider AT web.de>
1849 * src/pic16/genarith.c (genAddLit): simplified and fixed case where
1850 the left operand is shorter than the result (c* = lit-c* + int),
1852 * src/pic16/gen.c (genRightShift): check IS_SYMOP before accessing
1855 2006-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1857 * src/.version: increased version number to 2.5.5
1858 * src/SDCCmain.c (linkEdit): do not test for PIC16 target since, PIC16
1859 linking is done manually in pic16 port's _linkEdit,
1860 * src/SDCCsymt.c (compStructSize): for target PIC16 and shell variable
1861 PIC16_PACKED_BITFIELDS, compact bitfield structures as much as possible,
1862 * src/pic16/gen.c (aopForSym): when direct register name is WREG then
1863 allocate asmop as AOP_ACC,
1864 (aopForRemat): added parameter 'bool result' in function declaration,
1865 (pic16_aopGet): return AOP_ACC when accessing WREG,
1866 (pic16_popGetTempReg): minor modification,
1867 (pic16_popRegFromIdx): first try with 'pic16_regWithIdx' then with
1868 'pic16_allocWithIdx',
1869 (genPcall): removed ftype, usage of OP_SYM_TYPE asserted error when
1870 calling function in absolute addresses,
1871 (genAssign): take into account AOP_ACC asmop,
1872 * src/pic16/pcode.c (pic16_newpCodeOpReg): minor modifications,

1875 * (pic16_typeRegWithIdx): search 'pic16_dynInternalRegs' for given
1877 * (pic16_findFreeReg, pic16_findFreeRegNext): allocate new register via
1878 call to allocReg, not by manually allocating a new one,
1879 (pic16_assignRegisters): now before going through the register
1880 allocating functions mark all registers as free. This eliminates some
1881 side effects resulting from peephole parser done earlier in the backbone
1883 2006-03-13 Maarten Brock <sourceforge.brock AT dse.nl>
1885 * src/SDCCicode.c (geniCodeLogic),

1904 * src/mcs51/gen.c (newAsmop): set asmop.allocated to 1,
1905 (aopForSym, aopOp): increment asmop.allocated if reused,
1906 (freeAsmop): decrement asmop.allocated and check for zero instead of
1908 (freeForBranchAsmop): use asmop.allocated instead of asmop.freed,
1909 (genNot, genCpl, genUminus, genMinus, genMult, genDiv, genMod, genCmpGt,
1910 genCmpLt, genAndOp, genOrOp, genAnd, genOr, genXor, genRRC, genRLC,

1933 2006-03-06 Borut Razem <borut.razem AT siol.net>
1935 * support/regression/ports/pic16/spec.mk: link with libm18f.lib,
1936 made the linker quiet
1938 2006-03-06 Vangelis Rokas <vrokas AT users.sourceforge.net>
1940 * src/pic16/gen.c (genPcall): fixed bug #1443644
1941 * src/pic16/device.h (struct pic16_options_t): added 'int CATregs' flag
1942 which dumps before the function entry point a data byte which represents
1943 the number of the local variables used by the specified function, added
1944 'xinst' for initial support for Extended Instruction Support,
1945 * src/pic16/gen.c (aopForSym, pic16_aopGet): beautifications,
1946 (pic16_testStackOverflow): do not prefix GSTACK_TEST_NAME with
1947 port->fun_prefix anymore (may change later),
1948 (genFunction, genEndFunction): do not store/restore local registers for
1949 _main (this should take care the --main-return command line option in
1951 (genOr): removed some legacy pic-port instructions,
1952 * src/pic16/genarith.c (genAddLit): re-enabled old code because
1953 performing operations with SFR's causes data to be written more than
1954 once to each SFR. Perhaps SFRs should be handled in special cases...
1955 * src/pic16/glue.c: macros BIG_ENDIAN and BYTE_IN_LONG are moved to
1957 * src/pic16/main.c (_process_pragma): stack bound checking did not take
1958 into account for stack starting position,
1959 (struct OPTIONS pic16_optionsTable): added command line argument
1960 --extended or -y for Extended Instruction Support,
1961 * src/pic16/ralloc.c (pic16_decodeOp): added case for FUNCTION,
1962 (deassignLRs): *** perhaps the most important change, old 'for' code
1963 (commented out for reference), didn't account for some registers which
1964 were left marked 'not free' after a pointer operation. The change
1965 reduces register usage a lot in some cases
1967 2006-03-04 Borut Razem <borut.razem AT siol.net>

4322 * src/SDCCcse.c (cseBBlock): retain assignment to self when volatile
4323 * src/SDCCast.c (isLoopCountable): fixed bug #1161985
4325 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
4327 * device/lib/printf_large.c: removed inline assembly for portability and
4328 readability. Use printf_fast if speed or size are more important.
4329 * src/pic16/gen.c: removed conditions around use of DEBUGpc
4330 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
4332 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
4334 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
4335 prevent compiler warning
4337 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
4339 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
4340 moved to level 0 and declared as static. Also they are explicit
4341 placed in access bank. This was necessery because some times they
4342 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
4343 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
4344 optimizations. Currently only compare to unsigned char is implemented,
4345 * src/pic16/gen.c: added fReturnIdx array,
4346 * (struct resolvedIfx) is moved to gen.h and made public,
4347 * (struct _G): added sregsAlloc and sregsAllocSet fields,
4348 * (aopForSym): added an optimization to directly store in stack of
4349 the operand of a SEND iCode,
4350 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
4351 but as registers instead (AOP_REG) using the fReturnIdx array,
4352 * (pic16_freeAsmop): remove the freed register from the
4353 _G.sregsAlloc field,
4354 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
4355 a compare of 'WREG',
4356 * (pic16_popGetTempRegCond): changed function prototype, now
4357 function takes also a bitVector argument v which holds the current
4358 set of registers that are allocated for stack access by aopForSym,
4359 registers allocated in aopForSym for accessing stack symbols are not
4360 any more part of the functions usedRegs field,
4361 * (genCall): some times aopOp is called for a stack variable to be
4362 send, aopForSym might perform the push, if this is true make sure
4363 that genCall doesn't push the variable twice by testing _G.resDirect,
4364 * (genFunction): changed testing for unspecified interrupt number
4365 from 256 to INTNO_UNSPEC,
4366 * modified selection scheme of frame pointer generation. Previously
4367 if function did use local registers a frame pointer was generated,
4368 now a frame pointer is generated only if function has arguments
4369 (that need PLUSW2 register access), or has stack arguments, or the
4370 compiler is not instructed to omit the frame pointer,
4371 * (genEndFunction): before restoring local registers that were saved
4372 in the function preamble, also restore the registers that *might*
4373 have been allocated for stack access,
4374 * (genRet): removed some old comments,
4375 * (genCmp, the active (RN's) version): added a call to the
4376 pic16_genCmp_special function to perform the compare with a more
4377 robust and optimized way,
4378 * (genInline): a feature has been added in inline code generation,
4379 which allows a wildcard variable substitution when writing inline
4380 assembly. Code is incomplete and experimental therefore undocumented,
4381 * (genCast): changed order of aopOp for result and right to allow
4382 aopForSym to directly load the result if possible,
4383 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
4384 perform an optimized compare on some selected special occasions,
4385 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
4386 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
4387 generate an IVT any more,
4388 * src/pic16/main.c (pic16_optionsTable): added command line option
4390 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
4391 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
4393 * src/pic16/NOTES: Raphael Neider added in list of active developers
4394 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
4395 jumptable_end to prevent bug #,
4396 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
4397 inCond and outCond fields,
4398 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
4399 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
4400 turn off register spilling,
4401 * (packRegsForOneUse): synced with other ports' versions although it
4402 is not used currently,
4403 * (pic16_packRegisters): added an optimization while reading
4404 structure bitfields, some registers may be saved (malloc code is
4405 decreased by 80 bytes)
4407 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
4409 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
4410 left is a bitfield, if yes, then don't optimize assignment. Perhaps
4411 this can be optimized more?
4413 2005-03-10 Raphael Neider <rneider AT web.de>
4415 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
4416 genNearPointerGet): (hopefully) fixed access to bitfields via
4417 pointers (p->bitN = x; and x = p->bitN; failed)
4419 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

4462 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
4463 to keep the correct label reference count when adding/removing references
4464 to labels. A peephole file using this is appended to patch #1144962.

4743 access stack and frame pointers. They are initially assigned to
4744 point at pic16_pc_fsr1[lh] and pic16_pc_fsr2[lh] variables and other
4745 accessing SFRs. Updated all occurences of modification of stack or
4746 frame pointer in gen.c and pcode.c,
4747 * src/pic16/ralloc.c (serialRegAssign): fixed two bugs with
4748 assigning of a literal value to pointers,

5051 Adding support for replacing ljmps with sjmps in jumptables
5052 generated for switch statements. For now you need to set the
5053 environment variable SDCC_SJMP_JUMPTABLE to enable this.
5054 Now 4 algorithms for mcs51 jumptable generation are used:
5055 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
5056 addresses loaded pc-relative for up to 112 cases and stack-pushing
5057 target addresses loaded with offset from dptr for up to 256 cases.

5087 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
5089 * added libc directory. The current version of LibC contains string
5090 functions, ctype functions and macros and some functions of the
5091 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
5092 be extensively tested in the future. Standard disclaimer here.
5093 Library is not automatically build yet. But one can build it by

5105 * (pic16_storeForReturn): optimized return of 0,
5106 * (genCmp): experimental code for new genCmp which uses PIC18's
5107 special compare&skip instructions. Initial tests fail some times
5108 with variables grater than 1 byte in size, so new code is disabled,
5109 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
5111 * (genCast): began a fix to optimize the casting of a bit to another
5112 bit, now assigning a bitfield to another bitfield will fail, sorry,

5121 and 1 for banking instruction,
5122 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
5123 caused stop processing pCodes after a inline assembly block,
5124 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,

5126 registers when it shouldn't,
5127 * src/pic16/ralloc.c (allocReg): add preliminary support for
5128 supporting a limited set of temporary registers,
5130 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8135 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
8137 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
8138 loaded with the linker search paths (-L arguments) and the libraries
8139 to be linked with the current source (-l arguments). Changes
8140 currently will affect only the pic16 port.
8141 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
8142 include path the port specific paths and port specific libraries,
8143 * gplink command now contains the $3 argument,
8144 * src/pic16/device.h,
8145 * src/pic16/device.c,: structure PIC_device is made public and

8161 Documenting changes from previous commits.
8162 * configure.in (version 1.56),
8163 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
8164 when generating output files to configure the pic16 library,
8165 but now I've commented it out, since gputils aren't installed in the
8166 SF compile farm, so library won't compile
8168 * device/lib/Makefile.in (version 1.56): initially I've added in
8169 target 'all' the prerequestive 'model-pic16' so it compiled the
8170 pic16 library, but now I've commented it out for the same reasons
8172 * added targets 'model-pic16' and 'objects-pic16' to compile the
8174 * added target 'port-specific-objects-pic16' to handle the
8175 generated libraries and copy them into the build/ directory
8176 * added target 'clean-intermediate-pic16' to clean intermediate
8177 files into pic16 directory
8178 * in target 'installdirs' added line to create directory pic16 in

8182 added lines to copy all header files to installation path,
8183 * in target 'installdirs' added line create directory for pic16
8184 headers in the installation path

8200 option so that it actually works. Made it specific to the z80, since
8201 the gbz80 doesn't have these kinds of I/O ports.
8203 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8205 * device/include/z180.h,

8229 via literal number. The symbol is placed in the corresponding
8230 position of the data ram
8231 * (pic16_dump_section): relocatable and absolute uninitialized
8232 data are now emitted in sorted order to reduce section naming,
8233 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
8234 weren't marked as being in the access bank,

8311 * (pic16_get_op): modified to use the gpasm modifiers LOW,HIGH and
8312 UPPER for immediate operands,
8313 * src/pic16/pcodepeeph.c: added peephole support for the LFSR
8315 * src/pic16/peeph.def: all peepholes with movff are commented out,
8316 because there is a problem in the pcode peep optimizer,
8317 * src/pic16/ralloc.c: the register allocator can now reuse local
8318 function symbols for another function. This saves register usage.
8319 * src/pic16/ralloc.h: added flag isLocal in structure regs,
8321 Added file src/pic16/NOTES with information about program writing on
8322 the current port version.

8410 include information about variables allocated to the overlay
8413 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8415 * as/mcs51/lkmain.c: Help about -Y option

8425 LEFT_OP (left shift)
8427 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8429 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
8430 (default behaviour).
8432 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
8434 A python script to validate compiler diagnostic messages. It can be
8435 used to verify that sdcc complains about bad c source code and
8436 gives a good location of the error.
8437 * support/valdiag/Makefile,
8438 * support/valdiag/valdiag.py,
8439 * support/valdiag/tests/*
8441 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

8456 Bug reported from Jesus Calvino-Fraga
8458 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
8460 * sdcc.spec: updated
8461 * device/include/Makefile.in: don't install CVS directories
8462 * device/lib/Makefile.in: added removal of CVS directories after install
8463 * doc/Makefile: fixed install, added local_icons
8464 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
8465 * src/mcs51/gen.c (genRightShift): fixed bug #870788
8466 * src/ds390/gen.c (genRightShift): fixed bug #870788
8467 * src/SDCCast.c (decorateType): fixed bug #870781
8469 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
8471 PIC16 port related changes:
8472 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
8473 added variable stackPos,
8475 * gen.c: genCall, assignResultValue: added support for
8476 pushing/retrieving function parameters to/from stack,
8477 genFunction,genEndFunction: setup stack frame for the
8479 genAddrOf: will be changed according to bug 863624
8481 * added files genutils.c and genutils.h which contain gen*
8482 debugged and optimised functions extracted from gen.c
8484 * glue.c: added variable 'externs' which holds extern symbols,
8485 pic16emitRegularMap: is modified to properly handle relocatable
8486 symbols under the new scheme,
8487 pic16createInterruptVect: is modified
8488 pic16printPublics: is modified to emit 'global' assembler directives,
8489 added pic16_printExterns to print extern symbols,
8490 pic16glue: initializes stack/frame pointer in the beginning of
8491 the assembly output. Temporary hack, will be corrected later,
8492 because gplink yet does not support stack and SDCC does not
8493 yet support a type of crt0.o object to create the final binary.
8495 * Removed many lines that contain 8051 legacy code.
8496 * The code is finally placed under a 'code' directive.
8497 * Added port specific options.
8499 * _process_pragma: simplified since now we do not need *special*
8500 include file to define SFR registers. But a separate header
8501 will be needed. This will be developed later.
8502 * _pic16_parseOptions: added, parses port specific options:
8503 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
8504 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
8505 --preplace-udata-with=
8507 * _pic16_setDefaultOptions: modified to initialize section names,
8508 but hack is temporarly out of order since it needs improvement.
8509 * _pic16_genAssemblerPreamble: configuration words are emitted by
8510 their address instead of their name. This part is incomplete and
8511 supports only the 18Fxx2 devices. Other devices will emit an error
8512 during assembly since they do not contain the same set of config
8514 * _pic16_genIVT: is modified,
8516 * pcode.c: added definitions for some hardware registers that are needed
8518 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
8519 All PCI entries are updated. Now LFSR is supported.
8520 * Removed pic16_pciTRIS is mentioned by mdubuc in source
8521 * added pic16_newpCodeOpLit2 to support instructions with
8522 two literal arguments
8523 * pic16_pCode2str: corrected code that emits assembler instructions
8524 with two literal operands and those that have an access bit modifier
8525 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
8526 this fixes a bug which caused some labels to be lost, when an
8527 assembler directive was added, i.e. banksel,
8528 * pic16_FixRegisterBanking: improved logic that causes the insertion
8530 * InlineFunction: functions that are called once, are not any more
8531 inlined. This can be a port option in the future,
8533 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
8535 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
8536 hold the corresponding uninitialized symbols,
8537 * pic16_allocProcessorRegister: registers have explicit marked the
8539 * pic16_allocInternalRegister: registers are explicit marked as
8541 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
8542 processing list, so bit registers were lost,
8545 * ralloc.h: added field 'accessBank' and original symbol operand
8546 in register definition,
8547 * removed the field isMapped from register definition,
8549 ** Several functions have been removed from various sources:
8550 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
8551 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
8552 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
8553 pic16_assignRelocatableRegisters
8555 ** others have been introduced:
8556 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
8557 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
8559 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
8561 * support/scripts/inc2h.pl: changed definition of BIT_AT
8562 to emit 'sbit at' instead of 'bit at'. This was a request.
8564 PIC16 port related preliminary changes:
8565 * gen.c: prefixed function popRegFromString with
8566 pic16_ and all references to it corrected
8567 * pcode.c: all pic16_pc_* hardware registers prefixed
8568 with underscore (_),
8569 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
8570 * ralloc.c: newReg(): when register is REG_SFR then
8571 set address to rIdx,
8572 pic16_allocProcessorRegister(): marks register wasUsed=0
8573 pic16_writeUsedRegs(): added a call to assign processor
8574 registers via pic16_assignFixedRegisters
8576 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8578 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
8579 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
8580 variables in unused register banks. Also the SSEG is placed
8581 wherever there is enough space for it, and IDATA can be anywhere
8582 in internal RAM. For now compile using -Wl-Y[stack_size].
8583 The mem file is different for this option as well, since it
8584 makes no sense of talking about DSEG lenght.
8586 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
8588 * src/SDCClrange.c: fixed bug 869095 that caused segfault
8589 in certain cases, e.g. when ROM assignment, patch provided
8590 from Albert den Haan.
8592 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

9477 * src/SDCCast.c (decorateType): fixed bug #462971. Also, better
9478 support for standard C idiom of memory mapped variables; for
9479 example, *((xdata int*)0x1234) = 1 is now internally equivalent
9480 to xdata int at 0x1234 tempvar = 1.
9481 * sim/ucsim/z80.src/inst_xd.cc: fixed bug #805483 with patch
9482 provided by Akiya ISHIDA

9594 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
9595 fetching of the pointer
9596 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
9597 copied from genNearPointerSet()
9598 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
9599 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.
9600 If they pop r0/r1 they must be called in the opposite order than aopOp().

9613 2003-08-26 Bernhard Held <bernhard AT bernhardheld.de>
9615 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9616 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
9617 type for bits was changed. It resulted in bit variables becoming
9618 global, which is not permitted in PIC 14 assembly output.
9620 2003-08-23 Frieder Ferlemann <Frieder.Ferlemann AT web.de>

9635 A few small changes that speed up the peephole optimizer.
9639 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9641 Try to make the peephole optimizer smarter by maintaining
9642 an association between the assembly source code and the
9643 iCodes that originated them. Put this information to use
9644 with a new peephole rule condition "notVolatile" so that
9645 the rules can be aggressive yet still safe.
9650 * src/mcs51/peeph.def
9652 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9656 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
9657 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
9658 if the left or right operand symbols have the accuse flag set.
9660 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9662 Changed the type of the result of the ! (NOT) operator to char;
9663 previously it returned the same type as the source. This allows
9664 us to eliminate all the genFloatNot functions (all of its target
9665 implementations were very buggy) since !float can use the same
9668 * src/SDCCicode.c (ast2iCode): ! returns char

9675 2003-08-19 Bernhard Held <bernhard AT bernhardheld.de>
9677 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
9678 1. Interrupt would not compile properly. Ensure PCLATH register is saved
9679 during interrupts. Ensure WSAVE is located at a shared bank address.
9680 2. Fixed page selection in some places
9681 3. Fixed BTFSS/C to where necessary use registers directly and not simply
9682 the registers name strings.
9683 4. Fixed "signed / unsigned compare" compiler warnings.
9684 5. The PIC port manages its own allocation of the general purpose
9685 registers, but makes no attempt to reuse them. As a result when
9686 compiling it soon runs out of general purpose registers. Some
9687 additional code was added to the files pcode.c and device.c to walk
9688 through the function call tree and rename the registers so that they
9698 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions
9699 genPlus() & genMinus() when the result is the same as left or right

9705 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9707 Made bitfield a distinct type from bit so that bitfields
9708 convert as per ANSI C and bits retain their traditional
9709 boolean style behaviour. Implemented bitfield support in
9717 * src/ds390/gen.c: bit v bitfield split
9718 * src/z80/gen.c: New support for bitfields
9719 * support/regression/tests/bitfields.c: reenabled z80,
9722 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
9724 Rules 246.x, 247.x relate to bitfields, the others speed up
9725 access to xdata mapped I/O devices.
9727 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
9729 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9731 Cleaned up genPackBits and genUnpackBits and added two helper
9732 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
9733 for literal assignments in genPackBits (thanks to Frieder for
9739 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9741 Fixed bug #748310 (pointer to function type mishandled when the
9742 function name is omitted). Also fixed a SIGSEGV when a function
9743 attribute (reentrant, etc) is used on a non-function or on a
9744 function but misplaced before the parameter list.
9746 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
9748 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV
9749 * support/Util/SDCCerr.h,
9750 * support/Util/SDCCerr.c: Added func attr misuse error msg

9771 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
9773 Made the constant following the "interrupt" keyword optional. If
9774 omitted, the function will not automatically be given an entry
9775 in the interrupt vector table (similar to #pragma NOIV, but
9776 less syntacticly kludgy). The interrupt number is also now
9777 range checked. Also fixed a bug in the high order bit example

9791 * src/SDCCicode.c (operandOperation): rewritten some ops
9792 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
9793 * src/SDCCsymt.c (computeType): literals are handled the same way as any
9795 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
9796 be re-activated by defining REDUCE_LITERALS)

9798 unsigned, but are signed by default

10254 the regression tests I'm not brave enough to enable 245.b, 245.c
10255 * doc/sdccman.lyx: added latex preamble for hyperref package.
10256 Using pdflatex this will give you a hyperlinked pdf file with

10307 added if/endif conditional macros to remove options help
10308 messages from optionsTable when a port is not configured, added
10309 support for the PIc16 port in the ports table, when executing
10310 the compiler with no port specified on command line, a default
10311 port is selected with the new macro DEFAULT_PORT which is
10312 defined in port.h, in setDefaultOptions() linkOptions is removed
10313 from initialization assignment, since now it is a set,
10314 parseCmdLine uses setParseWithComma for linkOptions, in
10315 linkEdit() linkOptions are accessed with new function indexSet()
10316 which returns the i'th item of a set variable. See SDCCset.c, in
10317 linkEdit() when calling buildCmdLine(), added linkOptions as
10318 last argument. Now users can pass arguments to gplink via the
10319 -Wl option, main() uses pic16glue() to glue up pic16 programs

10332 * src/pic16/main.c: __config directives are commented out to stop
10333 gpasm complaining and test the linkage with gplink, _linkCmd and
10334 _asmCmd changed to be more gplink and gpasm friendly
10335 * src/pic16/peeph.def: peep rule 3 is commented out, since it
10336 produced an error when parsed, peep rule 12 is added to utilize
10337 movff, but it is commented out since the pCode does not support
10338 yet a command with 2 address arguments
10340 2003-05-18 <johan AT balder>
10342 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

11379 2002-01-05 Bernhard Held <bernhard AT bernhardheld.de>
11380 * src/SDCCmacro.c: MAX_STRING_LENGTH increased to 2048; was too small for regression tests

11390 2002-12-28 Bernhard Held <bernhard AT bernhardheld.de>
11391 * src/mcs51/peeph.def: added rules 234 and 235 from Frieder Ferlemann <frieder.ferlemann AT web.de>

11397 2002-12-27 Bernhard Held <bernhard AT bernhardheld.de>
11398 * as/mcs51/Makefile.in: fixed typo lkomf51.o -> lkaomf51.o
11400 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
11401 * src/mcs51/main.c: removed {bindir}{sep} from aslink
11403 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11405 * in /sdcc/as/mcs51/ changed these files in order to create an
11406 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
11407 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
11408 following files to include the previous two files: aslink.dsp,
11409 Makefile.aslink, Makefile.bcc, and Makefile.in.
11411 * Changed /sdcc/src/SDCCmain.c so it creates files with extension
11412 .adb instead of .cdb
11414 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11416 * /sdcc/as/mcs51/lklist.c: Now reports memory usage using the
11417 value from option --iram-size.
11419 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11421 * /sdcc/as/mcs51/lklist.c: added boundary check before using
11424 2002-09-18 <wiml AT hhhh.org>
11426 * SDCClrange.h: exposed setFromRange() and setToRange()
11427 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
11428 packRegsForAccUse() (bug 542397)
11429 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
11430 multiple times and emitting the fetch operations more than once
11431 added aopGetUsesAcc() function to allow binary operators to
11432 fetch their operands in the correct order; made genMinus() emit
11433 compact code for X = LITERAL - Y
11435 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11436 * /sdcc/as/mcs51/lklist.c: Fixed incorrect number of parameters to
11437 sprintf() in line 1267.
11439 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11440 * /sdcc/src/SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
11443 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
11444 Changes to aslink (All the changes are marked with 'JCF'):
11446 * /sdcc/as/mcs51/aslink.h: External definition of sflag and
11449 * /sdcc/as/mcs51/lkarea.c: Computes the size of area BSEG_BYTES from
11450 area BSEG. Also moves, if possible, the DATA area down into the internal
11451 ram so more space is available.
11453 * /sdcc/as/mcs51/lkdata.c: Definition of memory summary output flag
11456 * /sdcc/as/mcs51/lklist.c: For the BSEG area report the size in bits,
11457 not bytes. Function summary() which creates a memory usage summary
11458 file with extension .mem. Reports of overlaping stack and small stack
11459 size. If the space for the stack is less than 16 bytes aslink trows a
11462 * /sdcc/as/mcs51/lkmain.c: Creation of some of the default areas for
11463 the 8051. Option 'y' for memory summary output file.
11465 Changes to sdcc (All the changes are marked with 'JCF'):
11467 * /sdcc/src/SDCCglobl.h: External definition of RegBankUsed[4].
11469 * /sdcc/src/SDCCglue.c: If a register bank is used, creates an
11470 overlaying area for it (uses RegBankUsed[4]).
11472 * /sdcc/src/SDCCmain.c: Definition RegBankUsed[4]; marks register
11473 bank zero as used by default. By default aslink locates the stack
11474 (equivalent to --stack-after-data). Pass option 'y' to aslink for
11475 the creation of the .mem file. Delegates the allocation of data area
11476 to aslink (it is not longer 0x30 by default). If --stack-loc passes
11477 the begining of the stack area to aslink.
11479 * /sdcc/src/SDCCmem.c: If a register bank is used, marks it so
11480 glue() in SDCCglue.c creates an area for it.
11482 2002-09-03 Borut Razem <borut.razem AT siol.net>
11483 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
11484 sdcc/src/pic/glue.c:
11485 introduced atexit() handler for teporay files removal in case of
11486 errors, assertions, ...
11488 2002-08-29 Borut Razem <borut.razem AT siol.net>
11489 * sdcc/support/cpp2/auto-host_vc_in.h:
11490 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
11491 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
11492 Maybe there is a similar problem with BORLANDC? It should be checked!
11494 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
11495 corrected improper use of assert: the assignment to clr variable was done inside the assert.
11496 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
11497 was not executed, and the compiler (cl) launched a warning:
11498 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
11500 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
11501 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
11503 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
11504 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
11506 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11507 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
11508 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
11509 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11510 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
11511 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
11512 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
11513 - added Release configuration in VS projects
11514 - review of compiler an linker options
11515 - VC .exe files are generated in bin_vc directory, not to interfere
11516 with binaries generated from other projects (cygwin, mingw, bcc ...)
11518 * sdcc/src/yacc.dsp: added
11520 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
11521 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
11522 and insert the version number definitions from .version
11524 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
11526 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
11527 added - genarate auto-host.h using auto-host_vc_in.h as template
11530 removed from CVS, generated automatically
11532 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
11533 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
11535 2002-08-11 Borut Razem <borut.razem AT siol.net>
11536 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
11538 2002-08-10 Borut Razem <borut.razem AT siol.net>
11539 * src/SDCCmain.c (main):
11540 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
11541 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
11542 The consequence was that some temporary files were not removed.
11545 unification of code in functions tempfilename() and tempfile():
11546 function tempnam() is defined in Visual Studio 6.0 and .NET
11548 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
11550 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
11551 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
11552 - removed compiler command line option /WX: Treats all warnings as errors
11553 - update a list of source files, included into the project
11555 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
11556 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
11557 changed project type to Generic Project so that can be correcly converted to VS.NET project
11559 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
11561 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
11563 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
11565 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
11566 added return 0 statements after assert() to make compiler happy
11568 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
11569 added newline in the def file to keep MSC compiler satisfied
11571 * sdcc/src/z80/gen.c:
11572 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
11573 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
11574 - solved MSC error in function aopDump()
11576 * sdcc_vc.h: define PREFIX as "\\sdcc"
11578 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
11579 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
11581 2002-06-22 Scott Dattalo <scott AT dattalo.com>
11582 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
11583 - Rewrote the register banking algorithm.
11584 - Added pCode live-range analysis to registers (for now, only non-used and
11585 singly-used registers optimized away)
11587 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
11589 * 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.
11591 2002-05-10 Scott Dattalo <scott AT dattalo.com>
11592 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

11604 2002-04-15 Michael Hope <michaelh AT vroom>
11606 * device/lib/z80/printf.c (sprintf): Added.
11608 * src/z80/ralloc.c (packRegisters): Disabled pack HL use for GB as it's broken.
11610 * src/z80/peeph.def: Added transpose redundent load rule.
