Bug ID: 96751
Summary: overwriting libstdc++ for a default target during
building libraries for armv5te/mthumb-interwork
Product: gcc
Version: 9.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org

GCC configuration patch to reduce arm targets
Dear GCC team,
I noticed that during building multilib for armv5te/mthumb-interwork, libstdc++
and libsup++ are generated in a folder for a default target (arm_none_eabi/lib)
instead of arm_none_eabi/lib/armv5te/le/interwork. I think just this part of
the log file will be sufficient for describing a bug:

It happens only for armv5te. For example armv7 doesn’t have this issue. I have
tried on Linux Debian 10 and MinGW 9.2.0 on Windows 10 and in both I have
noticed the same issue. If you need a full log, I can provide it to you.
The command line which I have used to configure GCC is :
$SRCDIR/configure --host=$host --build=$build --prefix=$prefix --target=$target
--disable-nls --enable-languages=c,c++ --enable-multilib --enable-interwork
--disable-lto --disable-shared --disable-threads --disable-libmudflap
--disable-libssp --disable-libgomp --disable-libstdcxx-pch --disable-libffi
--without-headers --enable-poison-system-directories --disable-decimal-float
--disable-win32-registry --with-newlib --with-gcc --with-gnu-as --with-gnu-ld
'--with-host-libstdcxx=-static-libgcc -Wl,-Bstatic,-lstdc++,-Bdynamic -lm'
--with-sysroot=$prefix --with-gmp=$prefixlocal --with-mpfr=$prefixlocal
--with-mpc=$prefixlocal --with-isl=$prefixlocal --with-zstd=$prefixlocal
Before this command I did some other configuration of the target, you can find
a patch in a attachment. It is just additional configuration in t-arm-elf file
to reduce number of the arm targets.
I have tried with releases gcc_9.2.0 and gcc_10.1.0. In both of the releases, I
noticed this problem. I tried to update the source file, but I couldn’t find
it.
Please let me know if I can assist any further.
With best regards,
M.Eng. Filip Bascarevic
