1726 2004-01-16 Vangelis Rokas <vrokas AT otenet.gr>
1728 * src/SDCCmain.c (linkEdit): variable $3 of the linker command is
1729 loaded with the linker search paths (-L arguments) and the libraries
1730 to be linked with the current source (-l arguments). Changes
1731 currently will affect only the pic16 port.
1732 * src/pic16/main.c (_pic16_finaliseOptions): add to the linker
1733 include path the port specific paths and port specific libraries,
1734 * gplink command now contains the $3 argument,
1735 * src/pic16/device.h,
1736 * src/pic16/device.c,: structure PIC_device is made public and
1737 renamed to PIC16_device, the same for variable Pics which is renamed

1752 Documenting changes from previous commits.
1753 * configure.in (version 1.56),
1754 * configure: initially I've added AC_CONFIG_SUBDIRS(device/lib/pic16)
1755 when generating output files to configure the pic16 library,
1756 but now I've commented it out, since gputils aren't installed in the
1757 SF compile farm, so library won't compile
1759 * device/lib/Makefile.in (version 1.56): initially I've added in
1760 target 'all' the prerequestive 'model-pic16' so it compiled the
1761 pic16 library, but now I've commented it out for the same reasons
1763 * added targets 'model-pic16' and 'objects-pic16' to compile the
1765 * added target 'port-specific-objects-pic16' to handle the
1766 generated libraries and copy them into the build/ directory
1767 * added target 'clean-intermediate-pic16' to clean intermediate
1768 files into pic16 directory
1769 * in target 'installdirs' added line to create directory pic16 in
1770 the installation path
1772 * device/include/Makefile.in (version 1.11): in target 'install'
1773 added lines to copy all header files to installation path,
1774 * in target 'installdirs' added line create directory for pic16
1775 headers in the installation path

1790 * src/z80/main.c (_parseOptions): fixed the portmode= command line
1791 option so that it actually works. Made it specific to the z80, since
1792 the gbz80 doesn't have these kinds of I/O ports.
1794 2004-01-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
1796 * device/include/z180.h,

1820 via literal number. The symbol is placed in the corresponding
1821 position of the data ram
1822 * (pic16_dump_section): relocatable and absolute uninitialized
1823 data are now emitted in sorted order to reduce section naming,
1824 * src/pic16/ralloc.c (newReg): fixed bug with SFR's that
1825 weren't marked as being in the access bank,
1827 2004-01-13 Vangelis Rokas <vrokas AT otenet.gr>
1829 Added portion of GNU PIC Library under the directory
1830 device/include/pic16 and device/lib/pic16. These files
1831 contain the declarations of SFRs for the PIC18Fxx2 devices.
1832 The directory is initialized via configure from toplevel.

1861 * doc/sdccman.lyx: Moved and added some sections, small changes
1862 all over. Telling LaTeX to be less strict with word spacing
1863 to better keep the right margin. Changed some notes about
1864 maintainance of the ports in section 3.2.1 - is it OK like this?
1866 2004-01-11 Vangelis Rokas <vrokas AT otenet.gr>

2018 2004-01-06 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2020 * as/mcs51/lkmain.c: stack must be after data when option -Y is not used
2021 (default behaviour).
2023 2004-01-06 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
2025 A python script to validate compiler diagnostic messages. It can be
2026 used to verify that sdcc complains about bad c source code and
2027 gives a good location of the error.
2028 * support/valdiag/Makefile,
2029 * support/valdiag/valdiag.py,
2030 * support/valdiag/tests/*

2047 Bug reported from Jesus Calvino-Fraga
2049 2004-01-06 Bernhard Held <bernhard AT bernhardheld.de>
2051 * sdcc.spec: updated
2052 * device/include/Makefile.in: don't install CVS directories
2053 * device/lib/Makefile.in: added removal of CVS directories after install
2054 * doc/Makefile: fixed install, added local_icons
2055 * sim/ucsim/gui.src/Makefile.in: fixed an old typo
2056 * src/mcs51/gen.c (genRightShift): fixed bug #870788
2057 * src/ds390/gen.c (genRightShift): fixed bug #870788
2058 * src/SDCCast.c (decorateType): fixed bug #870781
2060 2004-01-06 Vangelis Rokas <vrokas AT otenet.gr>
2062 PIC16 port related changes:
2063 * device.c: removed pic16_finalMapping and pic16_finalMappingSize,
2064 added variable stackPos,
2066 * gen.c: genCall, assignResultValue: added support for
2067 pushing/retrieving function parameters to/from stack,
2068 genFunction,genEndFunction: setup stack frame for the
2070 genAddrOf: will be changed according to bug 863624
2072 * added files genutils.c and genutils.h which contain gen*
2073 debugged and optimised functions extracted from gen.c
2075 * glue.c: added variable 'externs' which holds extern symbols,
2076 pic16emitRegularMap: is modified to properly handle relocatable
2077 symbols under the new scheme,
2078 pic16createInterruptVect: is modified
2079 pic16printPublics: is modified to emit 'global' assembler directives,
2080 added pic16_printExterns to print extern symbols,
2081 pic16glue: initializes stack/frame pointer in the beginning of
2082 the assembly output. Temporary hack, will be corrected later,
2083 because gplink yet does not support stack and SDCC does not
2084 yet support a type of crt0.o object to create the final binary.
2086 * Removed many lines that contain 8051 legacy code.
2087 * The code is finally placed under a 'code' directive.
2088 * Added port specific options.
2090 * _process_pragma: simplified since now we do not need *special*
2091 include file to define SFR registers. But a separate header
2092 will be needed. This will be developed later.
2093 * _pic16_parseOptions: added, parses port specific options:
2094 --pgen-banksel, --obanksel=, --pomit-config-words, --pomit-ivt,
2095 --pleave-reset-vector, --penable-stack, --pstack-model, --debug-xtra
2096 --preplace-udata-with=
2098 * _pic16_setDefaultOptions: modified to initialize section names,
2099 but hack is temporarly out of order since it needs improvement.
2100 * _pic16_genAssemblerPreamble: configuration words are emitted by
2101 their address instead of their name. This part is incomplete and
2102 supports only the 18Fxx2 devices. Other devices will emit an error
2103 during assembly since they do not contain the same set of config
2105 * _pic16_genIVT: is modified,
2107 * pcode.c: added definitions for some hardware registers that are needed
2109 * added flag is2LitOp and variable pci_magic in pCodeInstruction.
2110 All PCI entries are updated. Now LFSR is supported.
2111 * Removed pic16_pciTRIS is mentioned by mdubuc in source
2112 * added pic16_newpCodeOpLit2 to support instructions with
2113 two literal arguments
2114 * pic16_pCode2str: corrected code that emits assembler instructions
2115 with two literal operands and those that have an access bit modifier
2116 * genericPrint: now PC_ASMDIR pCodes, can emit a label if it exists,
2117 this fixes a bug which caused some labels to be lost, when an
2118 assembler directive was added, i.e. banksel,
2119 * pic16_FixRegisterBanking: improved logic that causes the insertion
2121 * InlineFunction: functions that are called once, are not any more
2122 inlined. This can be a port option in the future,
2124 * pcode.h: added pCodeOpLit2 and added variable label in pCodeAsmDir
2126 * ralloc.c: added pic16_rel_udata and pic16_fix_udata variables which
2127 hold the corresponding uninitialized symbols,
2128 * pic16_allocProcessorRegister: registers have explicit marked the
2130 * pic16_allocInternalRegister: registers are explicit marked as
2132 * pic16_writeUsedRegs: pic16_dynDirectBitRegs was missing from the
2133 processing list, so bit registers were lost,
2136 * ralloc.h: added field 'accessBank' and original symbol operand
2137 in register definition,
2138 * removed the field isMapped from register definition,
2140 ** Several functions have been removed from various sources:
2141 BanksUsedFlow2,BanksUsedFlow,FixBankFlow,InstructionRegBank,
2142 pic16_addMemRange,pic16_isREGinBank,pic16_dump_map,pic16_dump_cblock
2143 isSFR,validAddress,mapRegister,assignRegister,pic16_assignFixedRegisters
2144 pic16_assignRelocatableRegisters
2146 ** others have been introduced:
2147 pic16_areRegsSame,pic16_dump_section,checkAddReg,pic16_groupRegistersInSection
2148 pic16_popGetLit2,pic16_popCombine2,pushw,pushaop
2150 2004-01-05 Vangelis Rokas <vrokas AT otenet.gr>
2152 * support/scripts/inc2h.pl: changed definition of BIT_AT
2153 to emit 'sbit at' instead of 'bit at'. This was a request.
2155 PIC16 port related preliminary changes:
2156 * gen.c: prefixed function popRegFromString with
2157 pic16_ and all references to it corrected
2158 * pcode.c: all pic16_pc_* hardware registers prefixed
2159 with underscore (_),
2160 pic16_popCopyGPR2Bit(): function sets register wasUsed=1
2161 * ralloc.c: newReg(): when register is REG_SFR then
2162 set address to rIdx,
2163 pic16_allocProcessorRegister(): marks register wasUsed=0
2164 pic16_writeUsedRegs(): added a call to assign processor
2165 registers via pic16_assignFixedRegisters
2167 2004-01-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
2169 * as/mcs51/aslink.h, as/mcs51/lkarea.c, as/mcs51/lkdata.c,
2170 as/mcs51/lkmain.c, as/mcs51/lkmem.c: 8051 linker can now pack
2171 variables in unused register banks. Also the SSEG is placed
2172 wherever there is enough space for it, and IDATA can be anywhere
2173 in internal RAM. For now compile using -Wl-Y[stack_size].
2174 The mem file is different for this option as well, since it
2175 makes no sense of talking about DSEG lenght.
2177 2004-01-02 Vangelis Rokas <vrokas AT otenet.gr>
2179 * src/SDCClrange.c: fixed bug 869095 that caused segfault
2180 in certain cases, e.g. when ROM assignment, patch provided
2181 from Albert den Haan.
2183 2004-01-01 Bernhard Held <bernhard AT bernhardheld.de>

2326 * src/mcs51/peephole.def,
2327 * src/ds390/peephole.def: using the atomic test and clear instruction jbc
2328 (allows non-interrupt and interrupt code to safely compete for a resource

3206 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3207 * src/pic/glue.c (pic14printPublics): fixed bug introduced when symbol

3226 A few small changes that speed up the peephole optimizer.
3230 2003-08-22 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3232 Try to make the peephole optimizer smarter by maintaining
3233 an association between the assembly source code and the
3234 iCodes that originated them. Put this information to use
3235 with a new peephole rule condition "notVolatile" so that
3236 the rules can be aggressive yet still safe.
3241 * src/mcs51/peeph.def
3243 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3247 * src/mcs51/gen.c (aopForSym, leftRightUseAcc),
3248 * src/ds390/gen.c (aopForSym, leftRightUseAcc): preserve A and B
3249 if the left or right operand symbols have the accuse flag set.
3251 2003-08-20 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3253 Changed the type of the result of the ! (NOT) operator to char;
3254 previously it returned the same type as the source. This allows
3255 us to eliminate all the genFloatNot functions (all of its target
3256 implementations were very buggy) since !float can use the same
3259 * src/SDCCicode.c (ast2iCode): ! returns char

3268 pic patch provided by Slade Rich <slade_rich AT yahoo.com>
3269 1. Interrupt would not compile properly. Ensure PCLATH register is saved
3270 during interrupts. Ensure WSAVE is located at a shared bank address.
3271 2. Fixed page selection in some places
3272 3. Fixed BTFSS/C to where necessary use registers directly and not simply
3273 the registers name strings.
3274 4. Fixed "signed / unsigned compare" compiler warnings.
3275 5. The PIC port manages its own allocation of the general purpose
3276 registers, but makes no attempt to reuse them. As a result when
3277 compiling it soon runs out of general purpose registers. Some
3278 additional code was added to the files pcode.c and device.c to walk
3279 through the function call tree and rename the registers so that they
3289 * src/pic/genarith.c: Fixed problems with PIC 14 port in functions

3296 2003-08-18 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3298 Made bitfield a distinct type from bit so that bitfields
3299 convert as per ANSI C and bits retain their traditional
3300 boolean style behaviour. Implemented bitfield support in
3308 * src/ds390/gen.c: bit v bitfield split
3309 * src/z80/gen.c: New support for bitfields
3310 * support/regression/tests/bitfields.c: reenabled z80,
3313 2003-08-17 Frieder Ferlemann <Frieder.Ferlemann AT web.de>
3315 Rules 246.x, 247.x relate to bitfields, the others speed up
3316 access to xdata mapped I/O devices.
3318 * src/mcs51/peeph.def: added 26 peepholes 246.x - 248.x, 180.x
3320 2003-08-16 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3322 Cleaned up genPackBits and genUnpackBits and added two helper

3332 Fixed bug #748310 (pointer to function type mishandled when the
3333 function name is omitted). Also fixed a SIGSEGV when a function
3334 attribute (reentrant, etc) is used on a non-function or on a
3335 function but misplaced before the parameter list.

3362 2003-08-13 Erik Petrich <epetrich AT ivorytower.norman.ok.us>
3364 Made the constant following the "interrupt" keyword optional. If
3365 omitted, the function will not automatically be given an entry
3366 in the interrupt vector table (similar to #pragma NOIV, but
3367 less syntacticly kludgy). The interrupt number is also now
3368 range checked. Also fixed a bug in the high order bit example
3375 * support/Util/SDCCerr.c
3376 * support/Util/SDCCerr.h

3900 support for the PIc16 port in the ports table, when executing
3901 the compiler with no port specified on command line, a default
3902 port is selected with the new macro DEFAULT_PORT which is
3903 defined in port.h, in setDefaultOptions() linkOptions is removed
3904 from initialization assignment, since now it is a set,
3905 parseCmdLine uses setParseWithComma for linkOptions, in
3906 linkEdit() linkOptions are accessed with new function indexSet()
3907 which returns the i'th item of a set variable. See SDCCset.c, in
3908 linkEdit() when calling buildCmdLine(), added linkOptions as
3909 last argument. Now users can pass arguments to gplink via the

4991 2002-12-26 Bernhard Held <bernhard AT bernhardheld.de>
4992 * src/mcs51/main.c: removed {bindir}{sep} from aslink
4994 2002-12-10 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
4996 * in \sdcc\as\mcs51\ changed these files in order to create an
4997 aomf51 file: aslink.h, lkdta.c, lklex.c, lklibr.c, lklist.c,
4998 lkmain.c. Also added: lkmem.c and lkaomf51.c. Changed the
4999 following files to include the previous two files: aslink.dsp,
5000 Makefile.aslink, Makefile.bcc, and Makefile.in.
5002 * Changed \sdcc\src\SDCCmain.c so it creates files with extension
5003 .adb instead of .cdb
5005 2002-11-09 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5007 * \sdcc\as\mcs51\lklist.c: Now reports memory usage using the
5008 value from option --iram-size.
5010 2002-09-20 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5012 * \sdcc\as\mcs51\lklist.c: added boundary check before using
5015 2002-09-18 <wiml AT hhhh.org>
5017 * SDCClrange.h: exposed setFromRange() and setToRange()
5018 * mcs51/ralloc.c: fixed over-eager packRegsForSupport() and
5019 packRegsForAccUse() (bug 542397)
5020 * mcs51/gen.c: MOVA() is now a function to avoid calling aopGet()
5021 multiple times and emitting the fetch operations more than once
5022 added aopGetUsesAcc() function to allow binary operators to
5023 fetch their operands in the correct order; made genMinus() emit
5024 compact code for X = LITERAL - Y
5026 2002-09-00 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5027 * \sdcc\as\mcs51\lklist.c: Fixed incorrect number of parameters to
5028 sprintf() in line 1267.
5030 2002-09-08 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5031 * \sdcc\src\SDCCglue.c: Generate areas REG_BANK_[0-3] only for 8051
5034 2002-09-04 Jesus Calvino-Fraga <jesusc AT ece.ubc.ca>
5035 Changes to aslink (All the changes are marked with 'JCF'):
5037 * \sdcc\as\mcs51\aslink.h: External definition of sflag and
5040 * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
5041 area BSEG. Also moves, if possible, the DATA area down into the internal
5042 ram so more space is available.
5044 * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
5047 * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
5048 not bytes. Function summary() which creates a memory usage summary
5049 file with extension .mem. Reports of overlaping stack and small stack
5050 size. If the space for the stack is less than 16 bytes aslink trows a
5053 * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
5054 the 8051. Option 'y' for memory summary output file.
5056 Changes to sdcc (All the changes are marked with 'JCF'):
5058 * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
5060 * \sdcc\src\SDCCglue.c: If a register bank is used, creates an
5061 overlaying area for it (uses RegBankUsed[4]).
5063 * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
5064 bank zero as used by default. By default aslink locates the stack
5065 (equivalent to --stack-after-data). Pass option 'y' to aslink for
5066 the creation of the .mem file. Delegates the allocation of data area
5067 to aslink (it is not longer 0x30 by default). If --stack-loc passes
5068 the begining of the stack area to aslink.
5070 * \sdcc\src\SDCCmem.c: If a register bank is used, marks it so
5071 glue() in SDCCglue.c creates an area for it.
5073 2002-09-03 Borut Razem <borut.razem AT siol.net>
5074 * sdcc/src/SDCCglue.c, sdcc/src/SDCCglue.h, sdcc/src/SDCCmain.c,
5075 sdcc/src/pic/glue.c:
5076 introduced atexit() handler for teporay files removal in case of
5077 errors, assertions, ...
5079 2002-08-29 Borut Razem <borut.razem AT siol.net>
5080 * sdcc/support/cpp2/auto-host_vc_in.h:
5081 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
5082 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5083 Maybe there is a similar problem with BORLANDC? It should be checked!
5085 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
5086 corrected improper use of assert: the assignment to clr variable was done inside the assert.
5087 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5088 was not executed, and the compiler (cl) launched a warning:
5089 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
5091 2002-08-28 Bernhard Held <bernhard AT bernhardheld.de>
5092 * src/SDCCglue.c (printIvalArray): iterative calculation of array length
5094 2002-08-28 Jesus Calvino-Fraga and Borut Razem <borut.razem AT siol.net>
5095 * sdcc/sdcc.dsw: added sdcpp, sdcppa, yacc, conf projects
5097 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5098 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
5099 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
5100 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5101 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
5102 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
5103 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
5104 - added Release configuration in VS projects
5105 - review of compiler an linker options
5106 - VC .exe files are generated in bin_vc directory, not to interfere
5107 with binaries generated from other projects (cygwin, mingw, bcc ...)
5109 * sdcc/src/yacc.dsp: added
5111 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
5112 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
5113 and insert the version number definitions from .version
5115 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
5117 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:
5118 added - genarate auto-host.h using auto-host_vc_in.h as template
5121 removed from CVS, generated automatically
5123 2002-08-25 Bernhard Held <bernhard AT bernhardheld.de>
5124 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
5126 2002-08-11 Borut Razem <borut.razem AT siol.net>
5127 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
5129 2002-08-10 Borut Razem <borut.razem AT siol.net>
5130 * src/SDCCmain.c (main):
5131 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
5132 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
5133 The consequence was that some temporary files were not removed.
5136 unification of code in functions tempfilename() and tempfile():
5137 function tempnam() is defined in Visual Studio 6.0 and .NET
5139 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
5141 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
5142 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:
5143 - removed compiler command line option /WX: Treats all warnings as errors
5144 - update a list of source files, included into the project
5146 * sdcc/src/avr/avra.dsp, sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
5147 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
5148 changed project type to Generic Project so that can be correcly converted to VS.NET project
5150 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
5152 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
5154 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
5156 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
5157 added return 0 statements after assert() to make compiler happy
5159 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
5160 added newline in the def file to keep MSC compiler satisfied
5162 * sdcc/src/z80/gen.c:
5163 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
5164 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
5165 - solved MSC error in function aopDump()
5167 * sdcc_vc.h: define PREFIX as "\\sdcc"
5169 2002-07-18 Bernhard Held <bernhard AT bernhardheld.de>
5170 * src/SDCCast.c (decorateType): fixed access to array of structures http://sourceforge.net/mailarchive/forum.php?thread_id=902690&forum_id=4107
5172 2002-06-22 Scott Dattalo <scott AT dattalo.com>
5173 * src/pic/*: Numerous bug fixes. Flow analysis has been enhanced.
5174 - Rewrote the register banking algorithm.
5175 - Added pCode live-range analysis to registers (for now, only non-used and
5176 singly-used registers optimized away)
5178 * src/pic/pcoderegs.[ch]: Added new files for pCode live-range analysis
5180 * 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.
5182 2002-05-10 Scott Dattalo <scott AT dattalo.com>

5205 * src/port.h: Removed the i186 and tlcs-900h ports as they weren't being being developed.
5207 * src/SDCCmain.c: Pulled the options definition out so that you can add port specific options without changing the main file.
5209 2002-03-28 Johan Knol <johan AT balder>
5211 * src/SDCCval.c: fixed bug #532436
5213 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5215 Added "char *Processor" field to the port structure.
5218 Added -p option. Allows port dependent processor to be specified.
5221 Initialized the new field char *Processor field to NULL in all ports
5224 Compiler generated registers for interrupt context saving
5225 were not getting allocated.
5227 2002-03-16 Sandeep Dutta <sandeep AT ddi.com>
5230 Fixed left shift. Will promote the left side of a left shift
5231 if a) left shifting more than size of operand or b) when assigned
5232 to something size > size of left side
5234 2002-03-14 Scott Dattalo <scott AT dattalo.com>
5236 tons of changes. Register allocation has been
5237 rewritten. Added customization for the various PICs. Flow
5238 analysis is restructured. ...
5244 Added. device.c is a PIC port hack to accomodate variations
5247 2002-03-13 Michael Hope <michaelh AT vroom>
5249 * src/z80/gen.c (genGenPointerGet): Fixed a bug where a pointer in HL is dereferenced into HL but HL is not spilled. Yeah.
5251 2002-03-04 johanknol <johanknol AT manik>
5253 * /src/SDCCval.c: fixed
5255 const unsigned char arr[][2] = { { 0, 1 } };
