1491 * src/SDCC.lex (isTargetKeyword, doPragma, pragma_tbl[]): new pragmas
1492 to enable/disable SDCC and C99 extensions/keywords (std_c89, std_sdcc89,
1493 std_c99, std_sdcc99). Also, equivalent command line options (--std-c89,
1494 --std-sdcc89, --std-c99, --std-sdcc99). SDCC specific keywords are
1495 always available in leading double underscore form. The C99 support is
1496 mostly missing, but it's a start.

1576 2005-03-15 Maarten Brock <sourceforge.brock AT dse.nl>
1578 * device/lib/printf_large.c: removed inline assembly for portability and
1579 readability. Use printf_fast if speed or size are more important.
1580 * src/pic16/gen.c: removed conditions around use of DEBUGpc
1581 * src/pic16/genutils.h: added define for DEBUGpc for MSVC
1583 2005-03-15 Vangelis Rokas <vrokas AT users.sourceforge.net>
1585 * src/pic16/genutils.c (pic16_genCmp_special): initialized offs to
1586 prevent compiler warning
1588 2005-03-14 Vangelis Rokas <vrokas AT users.sourceforge.net>
1590 * device/lib/pic16/startup/crt0i.c (_cinit): local variables where
1591 moved to level 0 and declared as static. Also they are explicit
1592 placed in access bank. This was necessery because some times they
1593 might cross memory bank boundaries. crt0iz.c is *NOT* updated!!!
1594 * src/pic16/device.h: added flag OPTIMIZE_CMP to enable some compare
1595 optimizations. Currently only compare to unsigned char is implemented,
1596 * src/pic16/gen.c: added fReturnIdx array,
1597 * (struct resolvedIfx) is moved to gen.h and made public,
1598 * (struct _G): added sregsAlloc and sregsAllocSet fields,
1599 * (aopForSym): added an optimization to directly store in stack of
1600 the operand of a SEND iCode,
1601 * (pic16_aopOp): don't return return registers as strings (AOP_STR)
1602 but as registers instead (AOP_REG) using the fReturnIdx array,
1603 * (pic16_freeAsmop): remove the freed register from the
1604 _G.sregsAlloc field,
1605 * (pic16_aopGet): in case AOP_STR, the compare to 'a' is changed to
1606 a compare of 'WREG',
1607 * (pic16_popGetTempRegCond): changed function prototype, now
1608 function takes also a bitVector argument v which holds the current
1609 set of registers that are allocated for stack access by aopForSym,
1610 registers allocated in aopForSym for accessing stack symbols are not
1611 any more part of the functions usedRegs field,
1612 * (genCall): some times aopOp is called for a stack variable to be
1613 send, aopForSym might perform the push, if this is true make sure
1614 that genCall doesn't push the variable twice by testing _G.resDirect,
1615 * (genFunction): changed testing for unspecified interrupt number
1616 from 256 to INTNO_UNSPEC,
1617 * modified selection scheme of frame pointer generation. Previously
1618 if function did use local registers a frame pointer was generated,
1619 now a frame pointer is generated only if function has arguments
1620 (that need PLUSW2 register access), or has stack arguments, or the
1621 compiler is not instructed to omit the frame pointer,
1622 * (genEndFunction): before restoring local registers that were saved
1623 in the function preamble, also restore the registers that *might*
1624 have been allocated for stack access,
1625 * (genRet): removed some old comments,
1626 * (genCmp, the active (RN's) version): added a call to the
1627 pic16_genCmp_special function to perform the compare with a more
1628 robust and optimized way,
1629 * (genInline): a feature has been added in inline code generation,
1630 which allows a wildcard variable substitution when writing inline
1631 assembly. Code is incomplete and experimental therefore undocumented,
1632 * (genCast): changed order of aopOp for result and right to allow
1633 aopForSym to directly load the result if possible,
1634 * src/pic16/genutils.c (selectCompareOp, pic16_genCmp_special): NEW,
1635 perform an optimized compare on some selected special occasions,
1636 * src/pic16/genutils.h: declaration of resolvedIfx structure from gen.c,
1637 * src/pic16/glue.c (pic16createInterrupVect): make sure we never
1638 generate an IVT any more,
1639 * src/pic16/main.c (pic16_optionsTable): added command line option
1641 * (_pic16_initPaths): when calling C preprocessor define pic18fXXXX
1642 macro too, when calling assembler define pic18fXXXX *and* __18Fxxxx
1644 * src/pic16/NOTES: Raphael Neider added in list of active developers
1645 * src/pic16/pcode.c (OPT_TYPE_STR): added strings jumptable_begin and
1646 jumptable_end to prevent bug #,
1647 * (pic16_pciADDWFC, ADDFWC, COMF, CLRF): added some missing flags in
1648 inCond and outCond fields,
1649 * src/pic16/pcoderegs.c (pCodeOptime2pCodes): add a fix for bug #,
1650 * src/pic16/ralloc.c (serialRegAssign): explicit set willCS to 0 to
1651 turn off register spilling,
1652 * (packRegsForOneUse): synced with other ports' versions although it
1653 is not used currently,
1654 * (pic16_packRegisters): added an optimization while reading
1655 structure bitfields, some registers may be saved (malloc code is
1656 decreased by 80 bytes)
1658 2005-03-12 Vangelis Rokas <vrokas AT users.sourceforge.net>
1660 * src/SDCCcse.c (cseBBlock): inside 'do operand lookup' loop test if
1661 left is a bitfield, if yes, then don't optimize assignment. Perhaps
1662 this can be optimized more?
1664 2005-03-10 Raphael Neider <rneider AT web.de>
1666 * src/pic16/gen.c (pic16_loadFSR0, genPackBits, genUnpackBits,
1667 genNearPointerGet): (hopefully) fixed access to bitfields via
1668 pointers (p->bitN = x; and x = p->bitN; failed)
1670 2005-03-09 Paul Stoffregen <paul AT pjrc.com>

1711 2005-02-20 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
1713 * src/SDCCpeeph.def: new keyword "labelRefCountChange" which allows peepholes
1714 to keep the correct label reference count when adding/removing references
1715 to labels. A peephole file using this is appended to patch #1144962.
1717 2005-02-14 Raphael Neider <rneider AT web.de>

2300 2004-11-28 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
2302 Adding support for replacing ljmps with sjmps in jumptables
2303 generated for switch statements. For now you need to set the
2304 environment variable SDCC_SJMP_JUMPTABLE to enable this.
2305 Now 4 algorithms for mcs51 jumptable generation are used:
2306 ljmp or sjmp jumptables for up to 16 cases, stack-pushing target
2307 addresses loaded pc-relative for up to 112 cases and stack-pushing
2308 target addresses loaded with offset from dptr for up to 256 cases.

2338 * (pic18f{242,252,442,452}.h): added T0CONbits structure and
2340 * added libc directory. The current version of LibC contains string
2341 functions, ctype functions and macros and some functions of the
2342 stdlib set (like malloc/free/atof/atoi etc...). All functions are to
2343 be extensively tested in the future. Standard disclaimer here.
2344 Library is not automatically build yet. But one can build it by
2345 invoking 'make' inside the libc directory.
2346 * added ADC library under libio. Preliminary version yet.

2356 * (pic16_storeForReturn): optimized return of 0,
2357 * (genCmp): experimental code for new genCmp which uses PIC18's
2358 special compare&skip instructions. Initial tests fail some times
2359 with variables grater than 1 byte in size, so new code is disabled,
2360 * (genUnpackBits, genPackBits): more optimizations in reading/writing,
2362 * (genCast): began a fix to optimize the casting of a bit to another
2363 bit, now assigning a bitfield to another bitfield will fail, sorry,
2364 * src/pic16/main.c: disabled the use of lr-support feature,
2365 * src/pic16/pcode.h: renamed PCASMDIR to PCAD,

2371 * (isBankInstruction): modified to return 0 for no banking instruction,
2372 and 1 for banking instruction,
2373 * (pic16_isPCinFlow): check for PCAD (assembler directives) too,
2374 caused stop processing pCodes after a inline assembly block,
2375 * (pic16_popCopyGPR2Bit): updated to match bitfields with offset,
2376 * src/pic16/pcoderegs.c: fixed a bug with eliminating some temporary
2377 registers when it shouldn't,
2378 * src/pic16/ralloc.c (allocReg): add preliminary support for
2379 supporting a limited set of temporary registers,
2381 2004-11-23 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2383 * src/hc08/gen.c (genAssign, genPointerGetSetOfs, genDataPointerGet,
2384 genDataPointerSet): ensure assignments always copy in MSB to LSB
2386 (loadRegFromAop): recognize CLRH optimization,
2387 (genFunction): optimize RECEIVE iCodes in reentrant functions
2389 2004-11-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2391 * src/SDCCmain.c (parseCmdLine, optionsTable[]): fixed bug with

5300 2004-01-25 Bernhard Held <bernhard AT bernhardheld.de>
5302 * src/SDCCast.c: added an additional type flow in decorateType() of
5303 opposite direction, see feature request #860006; it's enabled at runtime
5304 by setting the environment variable SDCC_NEWTYPEFLOW
5305 * src/SDCCast.h: changed prototype of decorateType()
5306 * src/SDCCglue.c (emitRegularMap): updated call of decorateType()
5307 * src/SDCCicode.c (geniCodeDivision) (geniCodeModulus): promotion from

5341 code / RAM are in the same page / bank. This means the linker can
5342 safely allocate code/RAM of separate ASM files to different pages/banks.
5343 * doc/sdccman.lyx: added Slade's tips
5344 * src/mcs51/peeph.def: fixed bug #880768

5386 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
5388 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
5389 loaded with the linker search paths (-L arguments) and the libraries
5390 to be linked with the current source (-l arguments). Changes
5391 currently will affect only the pic16 port.
5392 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
5393 include path the port specific paths and port specific libraries,
5394 * gplink command now contains the $3 argument,
5395 * src/pic16/device.h,
5396 * src/pic16/device.c,: structure PIC_device is made public and
5397 renamed to PIC16_device, the same for variable Pics which is renamed

5412 Documenting changes from previous commits.
5413 * configure.in (version 1.56),
5414 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
5415 when generating output files to configure the pic16 library,
5416 but now I've commented it out, since gputils aren't installed in the
5417 SF compile farm, so library won't compile
5419 * device/lib/Makefile.in (version 1.56): initially I've added in
5420 target 'all' the prerequestive 'model-pic16' so it compiled the
5421 pic16 library, but now I've commented it out for the same reasons
5423 * added targets 'model-pic16' and 'objects-pic16' to compile the
5425 * added target 'port-specific-objects-pic16' to handle the
5426 generated libraries and copy them into the build/ directory
5427 * added target 'clean-intermediate-pic16' to clean intermediate
5428 files into pic16 directory
5429 * in target 'installdirs' added line to create directory pic16 in
5430 the installation path

5433 added lines to copy all header files to installation path,
5434 * in target 'installdirs' added line create directory for pic16
5435 headers in the installation path

5451 option so that it actually works. Made it specific to the z80, since
5452 the gbz80 doesn't have these kinds of I/O ports.
5454 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
5456 * device/include/z180.h,

5480 via literal number. The symbol is placed in the corresponding
5481 position of the data ram
5482 * (pic16_dump_section): relocatable and absolute uninitialized
5483 data are now emitted in sorted order to reduce section naming,
5484 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
5485 weren't marked as being in the access bank,
5487 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
5489 Added portion of GNU PIC Library under the directory
5490 device/include/pic16 and device/lib/pic16. These files
5491 contain the declarations of SFRs for the PIC18Fxx2 devices.
5492 The directory is initialized via configure from toplevel.

5724 added variable stackPos,
5726 * gen.c: genCall, assignResultValue: added support for
5727 pushing/retrieving function parameters to/from stack,

5736 pic16emitRegularMap: is modified to properly handle relocatable
5737 symbols under the new scheme,

5743 because gplink yet does not support stack and SDCC does not
5744 yet support a type of crt0.o object to create the final binary.
5746 * Removed many lines that contain 8051 legacy code.
5747 * The code is finally placed under a 'code' directive.
5748 * Added port specific options.
5750 * _process_pragma: simplified since now we do not need *special*
5751 include file to define SFR registers. But a separate header
5752 will be needed. This will be developed later.
5753 * _pic16_parseOptions: added, parses port specific options:
5754 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
5755 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
5756 --preplace-udata-with=
5758 * _pic16_setDefaultOptions: modified to initialize section names,
5759 but hack is temporarly out of order since it needs improvement.
5760 * _pic16_genAssemblerPreamble: configuration words are emitted by
5761 their address instead of their name. This part is incomplete and
5762 supports only the 18Fxx2 devices. Other devices will emit an error
5763 during assembly since they do not contain the same set of config
5765 * _pic16_genIVT: is modified,
5767 * pcode.c: added definitions for some hardware registers that are needed
5769 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
5770 All PCI entries are updated. Now LFSR is supported.
5771 * Removed pic16_pciTRIS is mentioned by mdubuc in source
5772 * added pic16_newpCodeOpLit2 to support instructions with
5773 two literal arguments
5774 * pic16_pCode2str: corrected code that emits assembler instructions
5775 with two literal operands and those that have an access bit modifier
5776 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
5777 this fixes a bug which caused some labels to be lost, when an
5778 assembler directive was added, i.e. banksel,
5779 * pic16_FixRegisterBanking: improved logic that causes the insertion
5781 * InlineFunction: functions that are called once, are not any more
5782 inlined. This can be a port option in the future,
5784 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
5786 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
5787 hold the corresponding uninitialized symbols,
5788 * pic16_allocProcessorRegister: registers have explicit marked the
5790 * pic16_allocInternalRegister: registers are explicit marked as
5792 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
5793 processing list, so bit registers were lost,
5796 * ralloc.h: added field 'accessBank' and original symbol operand
5797 in register definition,
5798 * removed the field isMapped from register definition,
5800 ** Several functions have been removed from various sources:
5801 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
5802 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
5803 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
5804 pic16_assignRelocatableRegisters
5806 ** others have been introduced:
5807 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
5808 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
5810 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
5812 * support/scripts/inc2h.pl: changed definition of BIT_AT
5813 to emit 'sbit at' instead of 'bit at'. This was a request.
5815 PIC16 port related preliminary changes:
5816 * gen.c: prefixed function popRegFromString with
5817 pic16_ and all references to it corrected
5818 * pcode.c: all pic16_pc_* hardware registers prefixed
5819 with underscore (_),
5820 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
5821 * ralloc.c: newReg(): when register is REG_SFR then
5822 set address to rIdx,
5823 pic16_allocProcessorRegister(): marks register wasUsed=0
5824 pic16_writeUsedRegs(): added a call to assign processor
5825 registers via pic16_assignFixedRegisters
5827 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5829 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
5830 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
5831 variables in unused register banks. Also the SSEG is placed
5832 wherever there is enough space for it, and IDATA can be anywhere
5833 in internal RAM. For now compile using -Wl-Y[stack_size].
5834 The mem file is different for this option as well, since it
5835 makes no sense of talking about DSEG lenght.
5837 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
5839 * src/SDCClrange.c: fixed bug 869095 that caused segfault
5840 in certain cases, e.g. when ROM assignment, patch provided
5841 from Albert den Haan.

6082 2003-11-26 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6084 * src/SDCCast.c (decorateType): disabled a transformation I added in
6085 revision 1.188 (access to fields of a structure at an absolute address);
6086 it breaks with bitfields, extern declarations, and gcse analysis.
6087 * src/SDCCopt.c (isLocalWithoutDef): if ADDRESS_OF applied to a symbol, it
6088 could be assigned through a pointer, so don't complain.
6089 * src/SDCCast.c (astErrors),
6091 * src/SDCCglue.c (emitRegularMap): fixed bug #847813

6193 * src/mcs51/main.c: started fixing bug #737001 (SDCC not clearing
6194 uninitialized variables) for the mcs51. Set environment variable

6196 xdata initialization slightly shorter
6198 2003-11-12 Erik Petrich <epetrich AT ivorytower.norman.ok.us>

6845 * src/mcs51/gen.c (genNearPointerSet): added missing opcode for
6846 fetching of the pointer
6847 * src/mcs51/gen.c (genNearPointerGet): added reuse of PREG,
6848 copied from genNearPointerSet()
6849 * src/mcs51/gen.c (genNearPointerGet): don't pop r0/r1, if RESULTONSTACK
6850 * src/mcs51/gen.c: changed order of freeAsmop(left/right/result)-calls.

6866 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
6867 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol
6868 type for bits was changed. It resulted in bit variables becoming
6869 global, which is not permitted in PIC 14 assembly output.

6886 A few small changes that speed up the peephole optimizer.
6890 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6892 Try to make the peephole optimizer smarter by maintaining
6893 an association between the assembly source code and the
6894 iCodes that originated them. Put this information to use
6895 with a new peephole rule condition "notVolatile" so that
6896 the rules can be aggressive yet still safe.
6901 * src/mcs51/peeph.def
6903 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6907 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
6908 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
6909 if the left or right operand symbols have the accuse flag set.
6911 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6913 Changed the type of the result of the ! (NOT) operator to char;
6914 previously it returned the same type as the source. This allows
6915 us to eliminate all the genFloatNot functions (all of its target
6916 implementations were very buggy) since !float can use the same

6929 1. Interrupt would not compile properly. Ensure PCLATH register is saved
6930 during interrupts. Ensure WSAVE is located at a shared bank address.
6931 2. Fixed page selection in some places
6932 3. Fixed BTFSS/C to where necessary use registers directly and not simply
6933 the registers name strings.
6934 4. Fixed "signed / unsigned compare" compiler warnings.
6935 5. The PIC port manages its own allocation of the general purpose
6936 registers, but makes no attempt to reuse them. As a result when
6937 compiling it soon runs out of general purpose registers. Some
6938 additional code was added to the files pcode.c and device.c to walk
6939 through the function call tree and rename the registers so that they
6949 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

6956 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6958 Made bitfield a distinct type from bit so that bitfields
6959 convert as per ANSI C and bits retain their traditional
6960 boolean style behaviour. Implemented bitfield support in
6968 * src/ds390/gen.c: bit v bitfield split
6969 * src/z80/gen.c: New support for bitfields
6970 * support/regression/tests/bitfields.c: reenabled z80,
6973 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
6975 Rules 246.x, 247.x relate to bitfields, the others speed up
6976 access to xdata mapped I/O devices.
6978 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
6980 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6982 Cleaned up genPackBits and genUnpackBits and added two helper
6983 functions, emitPtrByteGet & emitPtrByteSet. Added optimizations
6984 for literal assignments in genPackBits (thanks to Frieder for
6990 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
6992 Fixed bug #748310 (pointer to function type mishandled when the
6993 function name is omitted). Also fixed a SIGSEGV when a function
6994 attribute (reentrant, etc) is used on a non-function or on a
6995 function but misplaced before the parameter list.
6997 * src/SDCC.y (abstract_declarator, abstract_declaractor2): fixed
6999 * src/SDCC.y (declarator2_function_attributes): avoided SIGSEGV

7022 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
7024 Made the constant following the "interrupt" keyword optional. If
7025 omitted, the function will not automatically be given an entry
7026 in the interrupt vector table (similar to #pragma NOIV, but
7027 less syntacticly kludgy). The interrupt number is also now
7028 range checked. Also fixed a bug in the high order bit example

7042 * src/SDCCicode.c (operandOperation): rewritten some ops
7043 (*, ==, unary_minus) to fix possible overflows and to accord with ANSI
7044 * src/SDCCsymt.c (computeType): literals are handled the same way as any
7046 * src/SDCCval.c (cheapestVal): removed, it doesn't accord with ANSI (can
7047 be re-activated by defining REDUCE_LITERALS)

7557 * src/SDCCmain.c: linkOptions is changed to set *,
7558 added if/endif conditional macros to remove options help
7559 messages from optionsTable when a port is not configured, added
7560 support for the PIc16 port in the ports table, when executing
7561 the compiler with no port specified on command line, a default
7562 port is selected with the new macro DEFAULT_PORT which is
7563 defined in port.h, in setDefaultOptions() linkOptions is removed
7564 from initialization assignment, since now it is a set,
7565 parseCmdLine uses setParseWithComma for linkOptions, in
7566 linkEdit() linkOptions are accessed with new function indexSet()
7567 which returns the i'th item of a set variable. See SDCCset.c, in
7568 linkEdit() when calling buildCmdLine(), added linkOptions as
7569 last argument. Now users can pass arguments to gplink via the
7570 -Wl option, main() uses pic16glue() to glue up pic16 programs

7582 * src/pic16/glue.c: commented out some error producing lines
7583 * src/pic16/main.c: __config directives are commented out to stop
7584 gpasm complaining and test the linkage with gplink, _linkCmd and
7585 _asmCmd changed to be more gplink and gpasm friendly
7586 * src/pic16/peeph.def: peep rule 3 is commented out, since it
7587 produced an error when parsed, peep rule 12 is added to utilize
7588 movff, but it is commented out since the pCode does not support
7589 yet a command with 2 address arguments
7591 2003-05-18 <johan AT balder>
7593 * src/ds390/gen.c (genArrayInit): removed obsolete and buggy ARRAYINIT

7620 2003-05-11 Borut Razem <borut.razem AT siol.net>
7622 * src/SDCCutil.c: WIN32 version of getBinPath() calls GetModuleFileName() to determine
7623 the path of bin directory, so that PATH is the only env. variable, which has to be set
7624 in case of standard installation.

8662 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
8663 .adb instead of .cdb
8665 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8667 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
8668 value from option --iram-size.
8670 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8672 * \sdcc\as\mcs51\lklist.c: added boundary check before using
8675 2002-09-18 <wiml AT hhhh.org>
8677 * SDCClrange.h: exposed setFromRange() and setToRange()
8678 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
8679 packRegsForAccUse() (bug 542397)
8680 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
8681 multiple times and emitting the fetch operations more than once
8682 added aopGetUsesAcc() function to allow binary operators to
8683 fetch their operands in the correct order; made genMinus() emit
8684 compact code for X = LITERAL - Y
8686 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8687 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
8688 sprintf() in line 1267.
8690 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8691 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
8694 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
8695 Changes to aslink (All the changes are marked with 'JCF'):
8697 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
8700 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
8701 area BSEG. Also moves, if possible, the DATA area down into the internal
8702 ram so more space is available.
8704 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
8707 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
8708 not bytes. Function summary() which creates a memory usage summary
8709 file with extension .mem. Reports of overlaping stack and small stack
8710 size. If the space for the stack is less than 16 bytes aslink trows a
8713 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
8714 the 8051. Option 'y' for memory summary output file.
8716 Changes to sdcc (All the changes are marked with 'JCF'):
8718 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
8720 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
8721 overlaying area for it (uses RegBankUsed[4]).
8723 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
8724 bank zero as used by default. By default aslink locates the stack
8725 (equivalent to --stack-after-data). Pass option 'y' to aslink for
8726 the creation of the .mem file. Delegates the allocation of data area
8727 to aslink (it is not longer 0x30 by default). If --stack-loc passes
8728 the begining of the stack area to aslink.
8730 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
8731 glue() in SDCCglue.c creates an area for it.
8733 2002-09-03 Borut Razem <borut.razem AT siol.net>
8734 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
8735 sdcc/src/pic/glue.c:
8736 introduced atexit() handler for teporay files removal in case of
8737 errors, assertions, ...
8739 2002-08-29 Borut Razem <borut.razem AT siol.net>
8740 * sdcc/support/cpp2/auto-host_vc_in.h:
8741 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
8742 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
8743 Maybe there is a similar problem with BORLANDC? It should be checked!
8745 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8746 corrected improper use of assert: the assignment to clr variable was done inside the assert.
8747 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
8748 was not executed, and the compiler (cl) launched a warning:
8749 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8751 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
8752 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
8754 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
8755 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
8757 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8758 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
8759 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
8760 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8761 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
8762 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
8763 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
8764 - added Release configuration in VS projects
8765 - review of compiler an linker options
8766 - VC .exe files are generated in bin_vc directory, not to interfere
8767 with binaries generated from other projects (cygwin, mingw, bcc ...)
8769 * sdcc/src/yacc.dsp: added
8771 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
8772 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
8773 and insert the version number definitions from .version
8775 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
8777 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
8778 added - genarate auto-host.h using auto-host_vc_in.h as template
8781 removed from CVS, generated automatically
8783 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
8784 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
8786 2002-08-11 Borut Razem <borut.razem AT siol.net>
8787 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
8789 2002-08-10 Borut Razem <borut.razem AT siol.net>
8790 * src/SDCCmain.c (main):
8791 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
8792 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
8793 The consequence was that some temporary files were not removed.
8796 unification of code in functions tempfilename() and tempfile():
8797 function tempnam() is defined in Visual Studio 6.0 and .NET
8799 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
8801 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
8802 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
8803 - removed compiler command line option /WX: Treats all warnings as errors
8804 - update a list of source files, included into the project
8806 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
8807 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
8808 changed project type to Generic Project so that can be correcly converted to VS.NET project
8810 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
8812 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
8814 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
8816 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
8817 added return 0 statements after assert() to make compiler happy
8819 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
8820 added newline in the def file to keep MSC compiler satisfied
8822 * sdcc/src/z80/gen.c:
8823 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
8824 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
8825 - solved MSC error in function aopDump()
8827 * sdcc_vc.h: define PREFIX as "\\sdcc"
8829 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
8830 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107

8869 2002-03-28 Johan Knol <johan AT balder>
8871 * src/SDCCval.c: fixed bug #532436
8873 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8875 Added "char *Processor" field to the port structure.
8878 Added -p option. Allows port dependent processor to be specified.
8881 Initialized the new field char *Processor field to NULL in all ports
8884 Compiler generated registers for interrupt context saving
8885 were not getting allocated.
8887 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
8890 Fixed left shift. Will promote the left side of a left shift
8891 if a) left shifting more than size of operand or b) when assigned
8892 to something size > size of left side
8894 2002-03-14 Scott Dattalo <scott AT dattalo.com>
8896 tons of changes. Register allocation has been
8897 rewritten. Added customization for the various PICs. Flow

9002 2002-02-21 Sandeep Dutta <sandeep AT ddi.com>
9004 * sdcc/src/SDCCloop.c:
9005 Previous fix was not good. basic blocks that have "break" or "return" are
9006 not really partof a loop , but live ranges used in these blocks should
9007 be live thru the entire loop, so set partOfLoop but don't add them to
9010 2002-02-21 <johan AT FRIJA>
9012 * src/SDCCcse.c: fixed bug #514308
9014 2002-02-20 Sandeep Dutta <sandeep AT ddi.com>
9017 Fixed BUG #519583. If a conditional block ended in a return/break
9018 statement inside a loop, it was not being considered part of the loop.
9020 * src/SDCCcflow.c: Removed fix (Fixed in SDCCloop.c)
9022 2002-02-10 Karl Bongers <karl AT turbobit.com>
9025 Fixed up SDCDB debugger somewhat. Updated debugger/README
9026 with lots of comments and notes.
9028 * device/examples/test2.c:
9029 Fix bug, "red" variable not being initialized(compiler complained).
9031 * device/examples/Makefile, examples/test3.c:
9032 Add Makefile in device/examples folder, compiles test3.c
9033 for use as a multiple module SDCDB test case.
9035 * sim/ucsim/cmd.src/cmdset.cc:
9036 Took out debug printfs in ucsim "next" command.
9039 Karl and Johan start ucsim XA support. Most dissassembly working,
9040 about 75% emulation done(plenty of work remaining).
9042 * sim/ucsim/z80.src:
9043 Add Z80 support to ucsim, add test-ucz80 regression test,
9044 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.

9080 set preprocessor defines (depending on options)
9082 * src/SDCCicode.c, src/SDCCicode.h:
9083 changes made to handle multiple sends & receives
9086 Added options --protect-sp-update (ds390) and --parms-in-bank1 (ds390/mcs51)
