HI !
GCC Version for compiling gcc 4.7.2 (Debian 4.7.2-5)
GCC Version being compiled 4.7.2
Distribution Debian wheezy
Host/Target amd64
For the qualification of GCC we wanted to compile gcc with code coverage
support so that we could get information about test-coverage of gcc itself
Unfortunately this did not work out yet. Just setting the CFLAGS in the
environment to include -fprofile-arcs -ftest-coverage does not work - the
build system removes them - looking at:
in src/Makefile.tpl:
...
# * Likewise, we force-disable coverage flags, since the installed
# compiler probably has never heard of them.
...
STAGE1_CONFIGURE_FLAGS = --disable-intermodule $(STAGE1_CHECKING) \
--disable-coverage --enable-languages="$(STAGE1_LANGUAGES)"
adding -fprofile-arcs -ftest-coverage and/or removing the --disable-coverage
did not resolve the issue either.
passing CFLAGS_FOR_TARGET=" -O2 -g -fprofile-arcs -ftest-coverage " on the
command-line also did not do it (even when --disable-coverage was removed) .
so I was just wondering if it is in principle possible to compile gcc with
gcc and enable coverage or if there is some principle problem with that ?
And if anyone has a hint how/where to enable coverage if it is possible I
would be thankful - have been trying to unravel the build but have not
been too succesful up to now...:)
thx!
