For the last couple of days, I have struggled in vain to produce a "working" mips-elf toolchain with newlib.
Over the years I have managed to build GCC/binutil/newlib toolchains for several targets including ARM, PowerPC, 68K, H8, AVR and their variants. However, I am now in search of a big endian MIPS toolchain. No problem ... right? ;-)
At this point I have tried various combinations of binutils, GCC and newlib versions.
One constant that I have noticed is that I get errors that look like this as the xgcc cross compiler attempts to build libgcc and others:
This warning comes from mips-elf-as as executed by GCC. Apparently, it does not like the ".size" directives produced by GCC?
The GCC build finally dies with the following error while attempting to link libgcc.a :
mips-elf-ranlib: ./libgcc.a: Malformed archive make[2]: *** [libgcc.a] Error 1
After some investigation it seems that the following libgcc objects cause some object "code" to be produced that results in the "Malformed archive".
_m16fix_truncdfsi.o _m16fix_truncsfsi.o _enable_execute_stack.o
Using "_enable_execute_stack.o" as an example (from libgcc2.c), I can create and compile a C file with the "identical" function and the result produced no warning or Malformed archive error.
I compare the actual "text" sections of these object files and they look identical, so I *assume* the difference lies in one of the other sections of the object file (e.g. debug info).
