1 2002-08-29 Borut Razem <borut.razem@siol.net>
2 * sdcc/support/cpp2/auto-host_vc_in.h:
3 re-definition of O_BINARY and other O_XXX as _O_BINARY and _O_XXX, so the problem
4 with the returned value from read() in sdcc/support/cpp2/cppfiles.c is solved for MSC.
5 Maybe there is a similar problem with BORLANDC? It should be checked!
7 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
8 corrected improper use of assert: the assignment to clr variable was done inside the assert.
9 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
10 was not executed, and the compiler (cl) launched a warning:
11 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
13 2002-08-28 Bernhard Held <bernhard@bernhardheld.de>

19 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
20 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
21 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
22 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
23 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
24 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
25 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
26 - added Release configuration in VS projects
27 - review of compiler an linker options
28 - VC .exe files are generated in bin_vc directory, not to interfere
29 with binaries generated from other projects (cygwin, mingw, bcc ...)
31 * sdcc/src/yacc.dsp: added
33 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
34 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
35 and insert the version number definitions from .version

43 removed from CVS, generated automatically
45 2002-08-25 Bernhard Held <bernhard@bernhardheld.de>
46 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
48 2002-08-11 Borut Razem <borut.razem@siol.net>
49 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
51 2002-08-10 Borut Razem <borut.razem@siol.net>
52 * src/SDCCmain.c (main):
53 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
54 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
55 The consequence was that some temporary files were not removed.
58 unification of code in functions tempfilename() and tempfile():
59 function tempnam() is defined in Visual Studio 6.0 and .NET
61 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
63 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,

69 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp:
70 changed project type to Generic Project so that can be correcly converted to VS.NET project
72 * sdcc/as/mcs51/asm.h: definition of PATH_MAX for MSC
74 * sdcc/src/SDCCast.c: solved MSC error in function decorateType()
76 * sdcc/src/SDCC.y: added missing ending ';' to rules to get rid of bison warnings
78 * dcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c:
79 added return 0 statements after assert() to make compiler happy
81 * sdcc/src/xa51/peeph.rul, sdcc/src/xa51/peeph.def, sdcc/src/z80/ralloc.c:
82 added newline in the def file to keep MSC compiler satisfied
85 - function strcasecmp() is not defined in MSC (and probably also in BORLANDC),
86 so it is replaced with STRCASECMP, which is defined as stricmp in case of MSC and BORLANDC
87 - solved MSC error in function aopDump()
89 * sdcc_vc.h: define PREFIX as "\\sdcc"
91 2002-07-18 Bernhard Held <bernhard@bernhardheld.de>

102 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba@cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
104 2002-05-10 Scott Dattalo <scott@dattalo.com>
105 * src/pic/*: Added support for multiplication. Fixed many,many bugs.
107 2002-04-22 Michael Hope <michaelh@vroom>

140 Added -p option. Allows port dependent processor to be specified.
143 Initialized the new field char *Processor field to NULL in all ports
146 Compiler generated registers for interrupt context saving
147 were not getting allocated.
149 2002-03-16 Sandeep Dutta <sandeep@ddi.com>
152 Fixed left shift. Will promote the left side of a left shift
153 if a) left shifting more than size of operand or b) when assigned
154 to something size > size of left side
156 2002-03-14 Scott Dattalo <scott@dattalo.com>
158 tons of changes. Register allocation has been
159 rewritten. Added customization for the various PICs. Flow
160 analysis is restructured. ...
166 Added. device.c is a PIC port hack to accomodate variations

264 2002-02-21 Sandeep Dutta <sandeep@ddi.com>
266 * sdcc/src/SDCCloop.c:
267 Previous fix was not good. basic blocks that have "break" or "return" are
268 not really partof a loop , but live ranges used in these blocks should
269 be live thru the entire loop, so set partOfLoop but don't add them to
272 2002-02-21 <johan@FRIJA>
274 * src/SDCCcse.c: fixed bug #514308
276 2002-02-20 Sandeep Dutta <sandeep@ddi.com>

298 Took out debug printfs in ucsim "next" command.
301 Karl and Johan start ucsim XA support. Most dissassembly working,
302 about 75% emulation done(plenty of work remaining).
305 Add Z80 support to ucsim, add test-ucz80 regression test,
306 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
307 Notice z80 compiler fails on examples/test3.c/crc code.
309 2002-01-30 Sandeep Dutta <sandeep@ddi.com>

1112 2001-09-03 Michael Hope <michaelh@juju.net.nz>
1114 * link/z80/aslink.h: Fixed path for PATH_MAX
1116 2001-09-02 Michael Hope <michaelh@juju.net.nz>
1118 * src/z80/gen.c (fetchLitPair): Changed so that it properly caches direct space references.
1120 * support/regression/tests/addsub.c: Added cases to cover all the +, - combinations.
1122 * support/regression/tests/uminus.c: Added a test for the unary minus operator.
1124 * src/z80/gen.c (genUminus): Fixed add, sub, and uminus on the gbz80 port for longs. Had to shift some functions about to do it.
1126 2001-09-01 Michael Hope <michaelh@juju.net.nz>
1128 * src/z80/gen.c: Fixed up generator to pass the regresion tests, specifically fixing loads for longs, genCmp, and turned on the map file.
1129 (genCmp): Fixed up genCmp for the GB with longs.
1131 * device/lib/gbz80/Makefile: Fixed up all the libraries to pass the regression tests.
1133 * support/regression/ports/host/spec.mk: Updated to compile with the new type specifiers.
1135 * device/lib/Makefile.in (Z80SOURCES): Removed old _mululong, _mulslong, and unneeded _mulint.
1137 * device/lib/_mullong.c (_mulslong): Changed to actually return a value :)
1139 2001-08-30 Paul Stoffregen <paul@pjrc.com>
1141 * added peepholes 223 to 231 to mcs51 port. These improve code when using large model.
1143 2001-08-30 Michael Hope <michaelh@juju.net.nz>
1145 * device/lib/gbz80/crt0.s (init): Fixed up support for the gbz80 such that it will at least run (and fail badly) the regression tests.
1147 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
1149 2001-08-29 Michael Hope <michaelh@juju.net.nz>
1151 * link/z80/aslink.h: Fixed long file name support. Is now based off PATH_MAX instead of a constant.
1153 * src/z80/gen.c: Fixed add and sub for the case where left or right are in static space.
