Hi all,
I'm trying to collect the coverage of gcc compiler used to build zephyr SDK.
Here the source code of Zephyr SDK , .
I'm using Zephyr SDK 0.13.1

NOTE: I'm interested in the coverage of crossgcc itself, not in the coverage of the source code built using gcc.

So I'm building the gcc toolchain enabling the coverage flags then I'm expecting to have the .gcda files generated when I run the gcc executable.

These are the steps I'm following:

  1.  I modified the x86_64-zephyr-elf.config adding following flags
     *   CT_BINUTILS_CFLAGS="-fprofile-arcs -ftest-coverage"
     *   CT_BINUTILS_LDFLAGS="-fprofile-arcs -ftest-coverage"
     *   CT_LIBC_NEWLIB_TARGET_CFLAGS="-fprofile-arcs -ftest-coverage"
     *   CT_LIBC_NEWLIB_CFLAGS="-fprofile-arcs -ftest-coverage"
     *   CT_GCC_CFLAGS="-fprofile-arcs -ftest-coverage"
     *   CT_GCC_LDFLAGS="-fprofile-arcs"
     *   CT_GCC_CXXFLAGS="-fprofile-arcs -ftest-coverage"
     *   CT_CC_CFLAGS="-fprofile-arcs -ftest-coverage"
     *   CT_CC_LDFLAGS="-fprofile-arcs"
     *   CT_CC_CXXFLAGS="-fprofile-arcs -ftest-coverage"
     *   CT_NEWLIB_NANO_CFLAGS="-fprofile-arcs -ftest-coverage"
  2.  I successfully build the SDK
  3.  I run the cross compiled GCC "gcc -h"
  4.  I'm expecting to have the .gcda files generated but there are no .gcda files.

Can someone help me?
Do you know how to generate the gcc coverage of cross-compiled gcc?
