1 2002-08-29 Borut Razem <borut.razem@siol.net>
2 * sdcc/src/ds390/ralloc.c, sdcc/src/mcs51/ralloc.c, sdcc/src/z80/ralloc.c:
3 corrected improper use of assert: the assignment to clr variable was done inside the assert.
4 In case that NDEBUG was defined, the assert macro was substituted with no-op, so the assignment
5 was not executed, and the compiler (cl) launched a warning:
6 ralloc.c(1442) : warning C4700: local variable 'clr' used without having been initialized
8 2002-08-28 Bernhard Held <bernhard@bernhardheld.de>
9 * src/SDCCglue.c (printIvalArray): iterative calculation of array length

14 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
15 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp,
16 sdcc/src/xa51/xa51.dsp, sdcc/src/avr/avra.dsp,
17 sdcc/src/ds390/ds390a.dsp, sdcc/src/mcs51/mcs51a.dsp,
18 sdcc/src/pic/pica.dsp, sdcc/src/z80/z80a.dsp,
19 sdcc/src/xa51/xa51a.dsp, sdcc/as/as_z80.dsp,
20 sdcc/as/aslink.dsp, sdcc/as/asx8051.dsp, sdcc/packihx/packihx.dsp:
21 - added Release configuration in VS projects
22 - review of compiler an linker options
23 - VC .exe files are generated in bin_vc directory, not to interfere
24 with binaries generated from other projects (cygwin, mingw, bcc ...)
26 * sdcc/src/yacc.dsp: added
28 * sdcc/config.dsp, sdcc/configure_vc.awk, sdcc/sdcc_vc_in.h:
29 added - genarate sdcc_vc.h using sdcc_vc_in.h as template
30 and insert the version number definitions from .version
32 * sdcc/support/cpp2/sdcpp.dsp: added - VC project for sdcpp
34 * sdcc/support/cpp2/sdcppa.dsp, sdcc/support/cpp2/auto-host_vc_in.h:

40 2002-08-25 Bernhard Held <bernhard@bernhardheld.de>
41 * support/scripts/inc2h.pl: use gputils or gpasm (from Nathan Hurst)
43 2002-08-11 Borut Razem <borut.razem@siol.net>
44 * support/Util/NewAlloc.c: removed unneeded #include "sdccconf.h" (suggested by Jesus Calvino-Fraga)
46 2002-08-10 Borut Razem <borut.razem@siol.net>
47 * src/SDCCmain.c (main):
48 file preOutName was unlinked before closed. This seems to be OK on UNIX and cygwin
49 platforms, but it doesn't work with Visual Studio: the opened file can not be removed.
50 The consequence was that some temporary files were not removed.
53 unification of code in functions tempfilename() and tempfile():
54 function tempnam() is defined in Visual Studio 6.0 and .NET
56 * sdcc/sdcc.dsw: removed project sdcpp, added project xa51a
58 * sdcc/src/src.dsp, sdcc/src/avr/avr.dsp, sdcc/src/ds390/ds390.dsp,
59 sdcc/src/mcs51/mcs51.dsp, sdcc/src/pic/pic.dsp, sdcc/src/z80/z80.dsp:

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

97 * support/scripts/inc2h.pl Kevin L. Pauba <klpauba@cox.net> submitted this perl script for converting MicroChip include files into SDCC Pic include files.
99 2002-05-10 Scott Dattalo <scott@dattalo.com>
100 * src/pic/*: Added support for multiplication. Fixed many,many bugs.

138 Initialized the new field char *Processor field to NULL in all ports
141 Compiler generated registers for interrupt context saving
142 were not getting allocated.
144 2002-03-16 Sandeep Dutta <sandeep@ddi.com>
147 Fixed left shift. Will promote the left side of a left shift
148 if a) left shifting more than size of operand or b) when assigned
149 to something size > size of left side
151 2002-03-14 Scott Dattalo <scott@dattalo.com>
153 tons of changes. Register allocation has been
154 rewritten. Added customization for the various PICs. Flow
155 analysis is restructured. ...
161 Added. device.c is a PIC port hack to accomodate variations

259 2002-02-21 Sandeep Dutta <sandeep@ddi.com>
261 * sdcc/src/SDCCloop.c:
262 Previous fix was not good. basic blocks that have "break" or "return" are
263 not really partof a loop , but live ranges used in these blocks should
264 be live thru the entire loop, so set partOfLoop but don't add them to
267 2002-02-21 <johan@FRIJA>
269 * src/SDCCcse.c: fixed bug #514308
271 2002-02-20 Sandeep Dutta <sandeep@ddi.com>

292 * sim/ucsim/cmd.src/cmdset.cc:
293 Took out debug printfs in ucsim "next" command.
296 Karl and Johan start ucsim XA support. Most dissassembly working,
297 about 75% emulation done(plenty of work remaining).
300 Add Z80 support to ucsim, add test-ucz80 regression test,
301 notice ucsim/z80 emulation fails on examples/test3.c/itoa code.
302 Notice z80 compiler fails on examples/test3.c/crc code.
304 2002-01-30 Sandeep Dutta <sandeep@ddi.com>

1105 * pragma noinduction broke memcpy on mcs51 large model. Moved it inside z80 optimization
1107 2001-09-03 Michael Hope <michaelh@juju.net.nz>
1109 * link/z80/aslink.h: Fixed path for PATH_MAX
1111 2001-09-02 Michael Hope <michaelh@juju.net.nz>
1113 * src/z80/gen.c (fetchLitPair): Changed so that it properly caches direct space references.
1115 * support/regression/tests/addsub.c: Added cases to cover all the +, - combinations.
1117 * support/regression/tests/uminus.c: Added a test for the unary minus operator.
1119 * 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.
1121 2001-09-01 Michael Hope <michaelh@juju.net.nz>
1123 * src/z80/gen.c: Fixed up generator to pass the regresion tests, specifically fixing loads for longs, genCmp, and turned on the map file.
1124 (genCmp): Fixed up genCmp for the GB with longs.
1126 * device/lib/gbz80/Makefile: Fixed up all the libraries to pass the regression tests.
1128 * support/regression/ports/host/spec.mk: Updated to compile with the new type specifiers.
1130 * device/lib/Makefile.in (Z80SOURCES): Removed old _mululong, _mulslong, and unneeded _mulint.
1132 * device/lib/_mullong.c (_mulslong): Changed to actually return a value :)
1134 2001-08-30 Paul Stoffregen <paul@pjrc.com>
1136 * added peepholes 223 to 231 to mcs51 port. These improve code when using large model.
1138 2001-08-30 Michael Hope <michaelh@juju.net.nz>
1140 * 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.
1142 * src/z80/gen.c (genPlus): Changed bad long add for gb to a fall through.
1144 2001-08-29 Michael Hope <michaelh@juju.net.nz>
1146 * link/z80/aslink.h: Fixed long file name support. Is now based off PATH_MAX instead of a constant.
1148 * src/z80/gen.c: Fixed add and sub for the case where left or right are in static space.

1152 * sim/ucsim/configure: little improvement of Cygwin-detection
1153 * sim/ucsim/configure.in: little improvement of Cygwin-detection
1154 * sim/ucsim/cmd.src/newcmdcl.h: include <sys/types.h> to define fd_set automated build
