[Introspector-developers] Build instructions for the cywin ssa branch

[James M. D. <mdu...@ya...>]

Here are the steps to build the cygwin gcc with the introspector
patches


0. Getting the sources 
cvs -d:pserver:an...@su...:/cvsroot/gcc login
# password is empty
cvs -d:pserver:an...@su...:/cvsroot/gcc co -r
tree-ssa-20020619-branch gcc

0.0.1 Patch :
http://introspector.sourceforge.net/cygwin/ssa-branch-patch.txt

0.1 Configure, make 

---------------------------------------------------------------------
1. hacking libjava configure 

In the libjava/configure : 
I hacked the test for the java thread model.

echo $ac_n "checking for thread model used by GCC""... $ac_c" 1>&6
echo "configure:3165: checking for thread model used by GCC" >&5
#THREADS=`$CC -v 2>&1 | sed -n 's/^Thread model: //p'`
THREADS=none
--------------------------------------------------------------------
2. Hacking libmudflap

For LibMudFlap 
I added this file for the libmudflap execinfo.h

#ifndef _EXECINFO_H
#define _EXECINFO_H

int backtrace(int, int);
int backtrace_symbols(int, int);

#endif

--------------------------------------------------------------------
3. The standard make did not build libgc or libjava
these need to be built separatly

4. you can debug by adding these commands to the compiler :
-fdump-translation-unit -g  -save-temps  --verbose
then you can extract the sources.

4.1 The dumper crashes on the following file
and will need to be debugged. 
/gcc/i686-pc-cygwin/libiberty/floatformat.c

To get the commands
rm floatformat.o 
make floatformat.o > command.sh
extract that, add -fdump-translation-unit -g  --verbose

BUT DONT ADD -save-temps, it you add this, the error does not happen

/cygdrive/c/development/testing/gcc/gcc/gcc/xgcc
-B/cygdrive/c/development/testing/gcc/gcc/gcc/
-B/usr/local/i686-pc-cygwin/bin/ -B/usr/local/i686-pc-cygwin/lib/
-isystem /usr/local/i686-pc-cygwin/include -c -DHAVE_CONFIG_H -O2 -g
-O2 -I. -I./../../include  -W -Wall -Wtraditional -pedantic
floatformat.c -fdump-translation-unit -g  --verbose -o floatformat.o

The command line that crashed this was  :
 /cygdrive/c/development/testing/gcc/gcc/gcc/cc1.exe -quiet -v -I.
-I./../../include -iprefix
/cygdrive/c/development/testing/gcc/gcc/gcc/../lib/gcc-lib/i686-pc-cygwin/3.4-tree-ssa/
-isystem /cygdrive/c/development/testing/gcc/gcc/gcc/include -isystem
/usr/local/i686-pc-cygwin/bin/include -isystem
/usr/local/i686-pc-cygwin/lib/include -D__GNUC__=3 -D__GNUC_MINOR__=4
-D__GNUC_PATCHLEVEL__=0 -D__CYGWIN32__ -D__CYGWIN__ -Dunix -D__unix__
-D__unix -isystem /usr/local/include -idirafter
/usr/local/i686-pc-cygwin/include -idirafter /usr/include -idirafter
/usr/local/i686-pc-cygwin/include/w32api -idirafter /usr/include/w32api
-DHAVE_CONFIG_H -isystem /usr/local/i686-pc-cygwin/include
floatformat.c -quiet -dumpbase floatformat.c -auxbase-strip
floatformat.o -g -g -O2 -O2 -W -Wall -Wtraditional -pedantic -version
-fdump-translation-unit -o
/cygdrive/d/DOCUME~1/mdupont/LOCALS~1/Temp/ccJGy9eG.s

Here are the versbose output of the command :
http://introspector.sourceforge.net/cygwin/floatformat.bug

4.2 the dumper crashed on the following files
/gcc/i686-pc-cygwin/libstdc++-v3/libsupc++/del_op.cc

this command reproduces the crash : 
/cygdrive/c/development/testing/gcc/gcc/gcc/cc1plus.exe -fpreprocessed
del_op.ii -quiet -dumpbase del_op.cc -auxbase-strip del_op.o -g -g -O2
-Wall -Wno-format -W -Wwrite-strings -Winline -version
-fno-implicit-templates -fdiagnostics-show-location=once
-ffunction-sections -fdata-sections -fdump-translation-unit -o del_op.s

The file is located here 
http://introspector.sourceforge.net/cygwin/del_op.ii

can someone else try compiling this,
With a standard gcc 3.2 and the -fdump-translation-unit
and the gcc saa branch?

Thanks,

mike
