Hi,
I've created cross-gcc (solaris 11 -> aix 4.3), it's installed in
/opt/xgcc-aix-4.3.0.0-47jan31. GCC built using sources from svn,
revision 183510. I removed references to c++1 from
BUILD_DIR/rs6000-ibm-aix4.3/libstdc++-v3/src/Makefile and commented
out the following lines in BUILD_DIR/gcc/include/stdint.h:
//typedef __INT_FAST8_TYPE__ int_fast8_t;
//typedef __INT_FAST16_TYPE__ int_fast16_t;
//typedef __UINT_FAST8_TYPE__ uint_fast8_t;
//typedef __UINT_FAST16_TYPE__ uint_fast16_t;
After these changes, I were able to build the whole thing.
Now, gcc works fine, that is I were able to compile few programs with
it and they seem to work as expected.
But g++ is another story. I have file main.cc:
int main() { }
Now:
alias xg++='/opt/xgcc-aix-4.3.0.0-47jan31/bin/rs6000-ibm-aix4.3-g++'
root@sol11x86:~/xtest/c++/main# xg++ main.cc -c
root@sol11x86:~/xtest/c++/main# ls
main.cc main.o
So far so good. Link!
root@sol11x86:~/xtest/c++/main# xg++ main.o -o main

Rats! Running with '-v' yields:

My guess is that assembler, linker, ar and ld work fine, as C programs
work, so most probably g++ produces bad assembly code for C++. Am I
right? Is there anything I can do about it? What information should I
provide? Assembler code for pbase_type_info.o, result of objdump
-<something> pbase_type_info.o, command used for building it?

I really hate this damn machine, I wish that they would sell it.
It never does just what I want, but only what I tell it.
