Hello,
Another thing on the TODO list is to work a bit more on cegcc patches
and especially because I think it's a bit too far from cygwin/mingw.
For instance I wanted to test Dw2 exception on wince platform and from
what I know
normally you only need to call configure with --with-dwarf2 and it will
define DWARF2_DEBUGGING_INFO but it doesn't work on cegcc.
When I compare with the first cegcc-4.4 version I made I can ses the
following differences :
gcc/config/arm/mingw32.h:
------------------------
/* This matches SHLIB_SONAME and SHLIB_SOVERSION in t-cygming. */
/* This matches SHLIB_SONAME and SHLIB_SOVERSION in t-cygwin. */
#if DWARF2_UNWIND_INFO
#define LIBGCC_EH_EXTN "_dw2"
#else
#define LIBGCC_EH_EXTN "_sjlj"
#endif
#define LIBGCC_SONAME "libgcc_s" LIBGCC_EH_EXTN "-1.dll"
gcc/config.gcc
------------------------
arm-*-mingw32*)
tm_file="${tm_file} arm/semi.h arm/aout.h arm/coff.h dbxcoff.h arm/pe.h
arm/wince-pe.h arm/mingw32.h"
xm_file=arm/xm-mingw32.h
# This has to match the logic for DWARF2_UNWIND_INFO in
gcc/config/arm/wince-pe.h
if test x$sjlj = x0; then
tmake_eh_file="i386/t-dw2-eh"
else
tmake_eh_file="i386/t-sjlj-eh"
fi
tmake_file="${tmake_file} ${tmake_eh_file} arm/t-arm arm/t-wince-pe
arm/t-cygming arm/t-mingw32"
gcc/config/arm/t-wince-pe (delete following lines)
-------------------------
# Version for mingw32ce
SHLIB_LC = -lmingw32 -lmingwex -lceoldname -lcoredll
# Version for cegcc
#SHLIB_LC = -lc -lcoredll
# This should go somewhere else.
# We are using SjLj EH.
EH_MODEL = sjlj
I tried to report my changes but it breaks cegcc so I hope that someone
with a good gcc knowledge will
have a look one day.
