I've built gcc 4.3.3 as a cross compiler for the psp (mips allegrex)
and out of the box it builds gcov. I can compile with -fprofile-arcs -
ftest-coverage and it instruments the code and links to the libgcov.a
without any erros, i put the generated elf into the psp and run it but
no .gcda file is generated. I looked into what libgcov.a contains and
used objdump to see what is the source of the _gcov.o file and this is
it:

it:
psp-objdump -S _gcov.o
_gcov.o: file format elf32-littlemips
Disassembly of section .text:
00000000 <__gcov_init>:
0: 03e00008 jr ra
4: 00000000 nop
00000008 <__gcov_flush>:
8: 03e00008 jr ra
c: 00000000 nop
How can i force libgcov.a to be build with valid code?

Were you able to generate the libgcov.a file ?
Can you pls tell how you were able to resolve this
problem ?
I am also looking for the same file to be generated,
but w.r.t MIPS environment.
Thx in advans,
