Error compiling gcc for fr30

Error compiling gcc for fr30

[Lars Poeschel]

Hi all!
I want to build a cross compiler for fr30 architecture (including c++) and 
configure in a separate build dir as follows:
../gcc-4.1.1/configure --prefix=/usr/cross --target=fr30-unknown-elf --with-gnu-as --with-gnu-ld --enable-languages=c --disable-libssp

Then is make and make install, which runs fine without any error.
Then I build newlib with my fresh fr30-unknown-elf-gcc and install it which 
also runs fine.

Then I configure gcc to build a c++ compiler:
../gcc-4.1.1/configure --prefix=/usr/cross --target=fr30-unknown-elf --with-gnu-as --with-gnu-ld --enable-languages=c,c++ --disable-libssp --with-newlib
The following make aborts with this error:

Can somebody please explain this a little bit more ? Is there something wrong 
with fr30's machine description ? Or did I something wrong compiling ? A 
similar error appears in all gcc versions since 4.0.0.
Is it really a bug in gcc ? Should I file a bug report ?

Thanks,

Lars

 All this should work in two steps, the latter configure first with the 
generic newlib headers
being preinstalled by copying them (with a single 'cp -r' command) and 
then producing newlib...
And so the error you got :

would have appeared in the first "build the C and C++ compilers with 
libiberty and libstdc++-v3
for the target"-step.  But then you maybe hadn't tried producing newlib 
with the "broken" GCC :-(

The earlier GCC I had tried to produce for 'fr30-elf' was the gcc-3.3.3 
in 2004 and also it crashed
somewhere in the 'libstdc++-v3' build, just like the gcc-4.1.1 here too :

/data1/home/src/gcc-4.1.1/build/fr30-elf/libstdc++-v3/include/bits/fstream.tcc:753: 
error: insn does not satisfy its constraints:
(insn 191 190 23 0 
/data1/home/src/gcc-4.1.1/build/fr30-elf/libstdc++-v3/include/bits/postypes.h:117 
(set (mem/s/c:SI (plus:SI (reg/f:SI 14 fp [42])
                (const_int 4 [0x4])) [27 <result>._M_state+4 S4 A32])
        (reg:SI 2 r2 [orig:1+4 ] [1])) 6 {movsi_internal} (nil)
    (expr_list:REG_DEAD (reg:SI 2 r2 [orig:1+4 ] [1])
        (nil)))
/data1/home/src/gcc-4.1.1/build/fr30-elf/libstdc++-v3/include/bits/fstream.tcc:753: 
internal compiler error: in copyprop_hardreg_forward_1, at regrename.c:1592

So, if it helps in any way, someone else got just the same crash just in 
the same place :-)

Most probbably there is something wrong....

  Your "optimization level" in compiling libstdc++-v3 was just the same 
'-Os' I had here, so it must
come from somewhere and be 'fr30' dependent.  Maybe changing it to '-O2' 
or to '-O' could help, I
will check that...  Anyway the '-Os' seems to cause a crash in 
libstdc++-v3 with 'fr30-elf' !

 Been there, seen that...  Only switching to '-O0' enabled the compile 
to succeed!  So I produced
this single module with -O0 and switching back to '-Os' with the next in 
turn helped only a while,
then it crashed again with:

internal compiler error: in copyprop_hardreg_forward_1, at regrename.c:1592

Compiling this too with '-O0' could help and then compiling again with 
'-Os' could get it forwards
to the next crash... Then the same thing again and again and finally the 
build could succeed... But
"What is broken, that is broken until being fixed!" :-(

Looking at the function 'copyprop_hardreg_forward_1()'  at 'regrename.c' 
and the line 1592 there
didn't help much. So making a bug report could help... BTW, the fr30 
port maintainer was told to
be Nick Clifton, nickc@redhat.com, so if you don't get any response, 
trying to contact him could
be one way, but maybe these crashes could have given enough info for 
some other to fix the
problem.  I myself have thought to learn the RTL "Really Soon Now" but 
let's see...

Only this and the last 'c++locale' seemed to require compiling them 
using '-O0'...  And the I had :

Dell:/data1/home/src/gcc-4.1.1/build # ls -l fr30-elf/libstdc++-v3/src/.libs
total 1152
drwxr-xr-x  2 root root    4096 2006-10-12 21:35 ./

A 'libstdc++.a' which required "cruntches" during its walk to the goal...
