Hi all,
We're trying to use GCOV together with the ARM-ELF development
environment.
Our installation is:
arm-elf-gcc: 3.4.3
arm-elf-ld: 2.15
arm-elf-ar, binutils: 2.15
(1) First we've compiled with the following standard gcc command line
gcc -fprofile-arcs -ftest-coverage -o sample sample.c
Running the image works fine, the expected gcov data file sample.da
has been created.
(2) After them, we've tried it with the arm-elf-gcc
arm-elf-gcc -fprofile-arcs -ftest-coverage -o sample sample.c
Running the image in the arm emulation arm-elf-run, no gcov data
file sample.gda has been created.
(3) Next, we've puted debugging printf to the fuctions gcov_init
and gcov_flush, after rebuilding libgcov.a and building sample.c
we've seen, that the code of these functions isn't entered.
What do we do wrong ?
thank you,
Franz Kaufleitner
